Have the Architects of the Covid-19 Pandemic Lost Touch with Reality?

 

Richard Gale & Gary Null PhD

Progressive Radio Network, May 28, 2021

 

As the pandemic wages into its second year, two diametrically opposing movements have consolidated in defiance against each other. The dominant contingent, represented by Biden, Congress, Anthony Fauci, Bill Gates and the mainstream media, has decided that any citizen who refuses a Covid-19 vaccine is a de facto enemy of the state. “Ultimately,” Joe Biden declared during another gaff remark about the status of the government’s vaccination campaign, “those who are not vaccinated will pay – end up paying the price.” Despite the dubious claims that the mRNA vaccines are approximately 95 percent effective, the unvaccinated therefore mysteriously pose a health risk to the vaccinated. Consequently, any punitive actions the federal and state governments undertake, including encouraging the social media to publicly shame and censor voices of caution and reason, are justified. 

 

In an effort to marginalize and socially victimize Israeli citizens who have postponed or refused vaccination, Netanyahu and his right-wing Knesset supporters passed a bill permitting personal information and data about unvaccinated citizens to be shared across government agencies and civil institutions.  Israel was named by Pfizer’s CEO Albert Bourla as the “world’s lab” for the company’s Covid-19 vaccine roll out. Contrary to the government’s response to criticisms, the unvaccinated are theoretically second-class citizens, branded with a “scarlet letter” depriving them of full engagement with Israeli society, including going to a restaurant, attending a movie, concert or athletic event. Many are unable to shop or go to work.  Even the staunch pro-Zionist New York Times indicated the government’s policies are “moving in the direction of a two-tier system for the vaccinated and unvaccinated.” 

 

An analysis comparing Israeli Covid-19 infection and vaccine-related deaths conducted by Dr. Herve Seligmann, an Israeli-national at Aix-Marseille University of Medicine’s Faculty of Emerging Infectious and Tropical Diseases, concluded that the Pfizer vaccine has caused “mortality hundreds of times greater in young people compare[d] to the mortality from coronavirus without the vaccine, and dozens of times more in the elderly, when the documented mortality from coronavirus is in the vicinity of the vaccine, thus adding greater mortality from heart attack, stroke, etc.”  Seligmann and his co-author Haim Yativ have referred to Netanyahu’s draconian policies with unsafe experimental vaccines as a “new Holocaust.”  A civilian organization, the Israeli People Committee, which includes many health professionals, released a devastating report on the number of injuries and deaths resulting from Pfizer’s vaccine.  It was during the peak of the government’s vaccination campaign that Israel experienced its highest mortality rate, especially among those between 20 and 29 years of age. The Committee reported, “26 percent of all cardiac events occurred in young people up to the age of 40, with the most common diagnosis in these cases being myositis and pericarditis.” Other adverse vaccine reactions included infarction, stroke, miscarriage, impaired blood circulation and pulmonary embolisms.

 

Nevertheless, Israel has become the poster child for far more than serving as Pfizer’s experimental laboratory for human ferrets. It also models a caste society of haves and have nots, the rewarded and the repressed, the vaccine-anointed and the untouchables, as strategized by the World Economic Forum’s future technological proposals in its Great Reset. Netanyahu is has seemingly fully bought into Schwab’s Fourth Industrial Revolution and it’s re-visioning of the very definition of the human species. Last October, during the WEF’s “Great Reset” virtual session, Netanyahu appeared with Colombia’s far-right president Ivan Dugue – polled as the least popular president during that nation’s history -- and Rwanda’s war criminal Paul Kagame, along with executives in the biotech and financial industries, to advocate on behalf of the Forum’s mantra that the pandemic is an “opportunity” to further mobilize global digital infrastructure systems, including Covid-19 vaccination verification via microchip technology.

 

Now we are witnessing Canada, the UK and the US aggressively mimicking Israel’s heavy-handed policies to establish full-spectrum social control and make efforts to implement a post-modern, technologically driven caste system. Although Biden stated he does not support a federal mandate on vaccination passports, it has been left to the individual states to decide. Democrat-controlled states, notably New York, are issuing vaccine passports as a ticket to allow the vaccinated to return to a new normal. Republican governors on the other hand have been quick to denounce them, and in the case of Arizona, Florida, Idaho, Montana and Texas to executively ban them altogether. Hopefully some of the bans will challenge many of the over one hundred private colleges and universities that decided to require students to be vaccinated before returning in Fall.

 

The mainstream corporate-Democrat media, led by the New York TimesWashington Post, the Daily BeastUS News & World Report, CNN, NPR and MSNBC spew volleys of baseless propaganda that the vaccines are effective and wholly safe. However, thousands of medical school professors, physicians and researchers worldwide are challenging this non-consensual assumption. They regularly point out that there is no reliable science to justify any such claims. This raises the question: what are the vaccines effective against? Surely not contracting SARS-CoV-2; thousands of fully-vaccinated people are testing positive with the infection. The CDC has reported “seven percent of those [vaccinated] who have been infected have been hospitalized and 74 have died.”

 

Government efforts to reach a fictitious herd immunity threshold will inevitably come at a great cost to human life. More recent studies suggest that an exceedingly large percentage of Americans should technically be exempt from Covid-19 vaccines.  The University of Michigan published a recent analysis in JAMA Network Open suggesting that three percent of vaccinated Americans taking immune-weakening drugs have an increased risk of hospitalization. The study is grossly conservative and undermines the breadth of the problem. The researchers only analyzed patients with private insurance, under the age of 65, and who were only prescribed immunosuppressive steroids, such as corticosteroids and prednisone. Other immunosuppressive drugs such “selective immunosuppressants” and calcineurin and interleukin inhibitors were seemingly excluded from the Michigan analysis. Thirty-three percent of the American population was therefore excluded from the study because, according to the CDC, only 66.8 percent of the population has private health insurance. New York University researchers reported in the British Medical Journal that a third of patients receiving methotrexate and TNF-inhibitors for immune-mediated inflammatory illnesses such as rheumatoid arthritis and psoriasis fail to achieve sufficient antibodies from the Pfizer vaccine. We are certain this will be found equally true for many other medications if or when studies are conducted. 

 

The CDC’s belief that only 4 percent of Americans are immune-compromised is a misleading under-estimation. The agency’s defining criteria is narrow and limited to HIV/AIDS and cancer patients, inherited genetic diseases, and patients who have undergone organ transplants and are prescribed immunosuppressive drugs. On the other hand, there are over 100 different autoimmune conditions, including type-1 diabetes, multiple sclerosis, blood cancers, lupus, fibromyalgia, rheumatoid and other types of arthritis, psoriasis, IgG4 disease, Hashimoto’s and Addison’s diseases, celiac disease, etc. These additional individuals, who account for over 50 million Americans, have malfunctioning immune systems that increase their susceptibility to both severe SARS-CoV-2 infections (if left untreated during its early stage) and a higher probability of vaccine adverse reactions. 

 

Consequently, a very conservative 17 percent of Americans are at greater risk from either viral infection or vaccine injury or death. This also excludes tens of millions of adults (30 percent) and children (40 percent) with chronic allergies and many of the over 89,000 cancer patients diagnosed annually and prescribed chemotherapeutic drugs. Every year, nearly two-thirds of all Americans require emergency medical care from allergic reactions alone.  Furthermore, those with certain immune weaknesses are less likely to generate sufficient vaccine-induced antibodies thereby making Covid-19 vaccination ineffective. 

 

Especially disturbing is that the clinical trials the FDA relied upon for Emergency Use Authorization for the past five months of the vaccination campaign were based upon enrollment of healthy participants. Only recently are clinical trials either underway or in recruitment to test the vaccines on participants with weakened immune systems, including small children and infants, and on pregnant women. In the meantime, millions of immunosuppressed people diagnosed with autoimmune conditions or pre-existing comorbidities, from young to old, are being indiscriminately injected. Given the CDC’s previous track record of reckless vaccination policies, upon these trials’ completion, we will surely see vaccination forced upon every infant carelessly. This has been a policy enacted so far on the elderly, the sickly, the immune-compromised, pregnant moms, and the rest of the nation. It is not irrational, therefore, to suspect that past and present Covid-19 trials have been conducted with malice of forethought and with the unconditional approval of our federal health officials. 

 

During the pandemic, the rapid ascent of our vaccine-addicted culture’s mantra of “vaccination at any cost” truly borders on medical malfeasance and criminal negligence. The overriding emphasis on vaccination and near total disregard for implementing very simple preventative measures to inhibit infections from progressing in severity. If our health policymakers were wise men and women, alternative treatments such as ivermectin, hydroxycholoroquine, and more recent inexpensive off-patent drugs, which have been shown to be highly effective for early stage treatment and being widely prescribed elsewhere in the world, would be permitted and encouraged without reservation. There would be no reason to wait for a novel drug costing thousands of dollars per patient to arrive.  And we still await that magic bullet drug because the previous one, remdesivir, was faulty blank. This is just another example of the institutionalized pathology that infects our health agencies. 

 

There is no convincing science to support our federal officials belief that a previously infected person requires a Covid-19 vaccine to acquire immunity. In fact, more recent research indicates the opposite and goes directly against the intellectually fetid arguments of the now disgraced financier Bill Gates that every person on the planet should be vaccinated without exception. Johns Hopkins University professor Dr. Marty Makary has put forth the evidence that “natural immunity works.” Makary notes that it is only the rare instance when a person is being re-infected. Washington University School of Medicine reported this month that even mild Covid-19 infections induce long lasting antibody protection. The study’s lead researcher Dr. Ali Ellebedy stated,

 

"Last fall, there were reports that antibodies wane quickly after infection with the virus that causes COVID-19, and mainstream media interpreted that to mean that immunity was not long-lived… But that's a misinterpretation of the data. It's normal for antibody levels to go down after acute infection, but they don't go down to zero; they plateau. Here, we found antibody-producing cells in people 11 months after first symptoms. These cells will live and produce antibodies for the rest of people's lives. That's strong evidence for long-lasting immunity."

 

The information we were fed to downplay natural immunity was wrong at best, and more likely a lie, in order to further persuade the public into the importance of the vaccines to return their lives to normal. Another study appearing in this month’s Journal of Infectious Diseases found that “SARS-CoV-2 specific immune memory response [following infection] persists in most patients nearly one year after infection.” The Covid-19 vaccines can’t make the same promise. In fact, more reports show that  fully vaccinated persons are becoming infected. 

 

But it gets worse.  

 

The pro-vaccine argument wrongly assumes that anyone who refuses the Covid-19 vaccines is therefore anti-vaxxer. We would argue it is rational caution in the face of a national healthcare system indebted to the pharmaceutical industry and that is rapidly losing public trust. Likewise, if a doctor is successfully treating hundreds of patients without a reported death with cheap, effective drugs, she or he is canceled and ridiculed as a quack. Instead of open dialogue and debate, those who challenge the Medical Church Scientific are censored by Google and from all social platforms, such as Facebook, Twitter and Wikipedia. This is despite the impeccable credentials of many medical professionals abiding by the precautionary principle and who dare to challenge Anthony Fauci and the global vaccine czar Bill Gates, whose faux philanthropy is nothing less than another profitmaking enterprise like Microsoft. 

 

Conflicts of interests, both financial and non-financial, are endemic in our medical system. Therefore it becomes increasingly more difficult to trust any clinical study or government policy that is based upon flawed evidence submitted by a drug maker that fails to undergo a thorough independent and impartial review by qualified medical experts. There is a clear psychological reason for this. Many psychologists have pointed out over the years that “cognitive bias,” “motivated reasoning” and the heuristics driving the evaluation of clinical trial data and the subsequent institutional regulatory review and decision-making are deeply contrary and undermine the entire evidence-based criteria that should oversee what drugs, vaccines, medical devices, therapeutic protocols should be recommended or approved for use upon the public.  

 

The late Scott Lilienfeld, a professor of psychology at Emory University, writes, “Clinicians are subject to the same errors in thinking that affect virtually all people. In particular, practitioners must be wary of (a) the misuse of certain heuristics (e.g., availability, representativeness) and (b) cognitive biases (e.g., confirmation bias, hindsight bias) in their everyday work.” Although Lilienfeld is singling out clinical physicians, it applies more rigorously and accurately to the pharmaceutical presidents, CEOs and chief science officers overseeing vaccine development who have stock prices to reach and shareholders to please.  Cognitive bias equally plagues the entire executive hierarchy at the CDC, NIAID, FDA and HHS who are beholden to the gaping revolving door between these agencies and private industry and their revenues. Writing about the deep ethical concerns behind bias in our medical institutions, Dr. Thomas Murray, President of the Hastings Center, states, “For scientists on a panel of the Food and Drug Administration, for example, it isn’t immediately clear to whom they owe their primary loyalty.”  Such biases, Murray believes, have completely destroyed the credibility of the World Health Organization.  

 

The fact that rates to reproduce medical clinical trials are so poor, according to behavioral economist Susann Fielder at the Max Planck Institute, is that “cognitive biases may be a reason for that.”  It also explains why Stanford University Medical School professor John Ioannidis argues, “most published research findings are false,” and “an estimated 85 percent of research resources are wasted.” Junk science based upon bias should also include every vaccine application submitted to the FDA for regulatory approval, since the vaccine companies are privileged to cherry-pick whichever trials they want to submit to create the most promising portfolio. 

 

One could review all of the official decisions made during the past 17 months – by Anthony Fauci, Trump and Biden and the naïve stances in both political parties – and should easily observe the frailties of cognitive bias and repeated contradictions throughout. None whatsoever are reliably truthful. And of course, cognitive bias leads to cognitive dissonance, such as denying that one has a bias or resorting to flagrant rejection and disparagement in order to avoid any scientific data that conflicts with one’s unfounded beliefs.

 

We now live in a nation of medicine by bureaucratic decree rather than by immunological science. This is postmodern cultism at its worst because it hides behind the veneer of being scientific. And it has the full support of a political technocracy that can ordain authoritarian laws. There is a dire need for a collective epiphany. All of us are experiencing the pandemic as a failed experiment orchestrated by institutions that have lost touch with reality. And it has been a very deadly experiment due to the extraordinary incompetence of our medical-degreed bureaucrats. Sadly the decades of institutional ineptitude has had to reach national and perhaps global awareness at this time when the powers that possess every technological tool at their disposal to conduct wide surveillance, pass undemocratic and draconian laws with full impunity, and control the fenced sheep within the mainstream media.

I Never Trusted Bill Gates, Nor Should You

While leading a Senate investigation, I tracked a corrupt pharmaceutical executive right into the lobby of the much-vaunted Bill and Melinda Gates Foundation—Bill Gates did nothing.

 

The DisInformation Chronicle,

 

https://disinformationchronicle.substack.com/p/i-never-trusted-bill-gates-nor-should

 

The last year has not been kind to Bill Gates. 

For two decades, Gates has shoveled out buckets of cash through the Bill and Melinda Gates Foundation to transform himself from despised 1990’s software monopolist to a present-day public health intellectual—a miraculous, money-fueled metamorphosis. But that reputational makeover has stumbled, as a series of critical articles have tarnished Gates’ paid-for golden image and cast doubt on his credibility. However, long before these articles came to light, I already knew that Gates could not to be trusted. 

A decade ago, I led a Senate investigation into a multi-billion-dollar diabetes drug sold by GlaxoSmithKline (GSK) that government scientists found to have caused around 83,000 heart attacks. During this federal investigation, I uncovered multiple examples of GSK officials intimidating medical experts who decried the drug’s dangers. A leader in this campaign was GSK’s chairman of research and development, Dr. Tadataka (Tachi) Yamada. 

By the time our committee uncovered GSK’s coercion campaign, Yamada had left the company to run Gates’ global health program. And yet, as the media outlets reported on Yamada’s prior role bullying physicians who tried to warn about the drug’s dangers, the Gates Foundation ignored this public outcry and allowed Yamada to maintain his pulpit as global health protector.

Twenty years back, journalists scrutinized Gates’ foundation as a vehicle to enrich himself and polish his appearance. But over the years, reporters began to forget Gates’ past and provide him a platform to puff himself up as scientific expert, despite his having no medical or scientific credentials. Bill Gates’ sculpted persona as health policy guru began to wobble last summer, however, precisely because of revelations showing the tools he had used to improve his media cachet.

In August 2020, Tim Schwab published an article in the Columbia Journalism Review exposing around $250 million in grants that Gates was throwing at journalism outlets including the BBC, NBC, Al Jazeera, ProPublica, National Journal, The Guardian, Univision, Medium, the Financial Times, The Atlantic, the Texas Tribune, Gannett, Washington Monthly, Le Monde, and the Center for Investigative Reporting. 

A later article in The Nation spotlighted Gates’ potential to profit from investments in companies situated to reap a windfall from the COVID pandemic. And another report in The Nation found that Gates’ funding has stifled debate in public health—described as “the Bill chill”—as organizations are reluctant to bite the hand that feeds them.

These revelations came as little surprise to me. Back in 2007, I was working as an investigator for the Senate Finance Committee and learned first-hand that Bill Gates does not put the public first. That year, I wrote the Senate Finance Committee’s report showing that, shortly after the GSK diabetes drug Avandia came on the market in 1999, the company attacked and silenced several scientists including Dr. John Buse, a professor of medicine at the University of North Carolina. 

GSK began to bully Dr. Buse after he gave talks stating that Avandia might increase cardiovascular problems such as heart attacks. By the time we released the 2007 report, FDA scientists estimated that Avandia had caused approximately 83,000 heart attacks.

When Dr. Buse began warning physicians about the drug, Dr. Yamada was at GSK and contacted Dr. Buse’s department chairman to complain. In an email discussing Dr. Buse with GSK’s CEO and other executives, Dr. Yamada wrote: 

In any case, I plan to speak to Fred Sparling, his former chairman as soon as possible. I think there are two courses of action. One is to sue him for knowingly defaming our product even after we have set him straight as to the facts—the other is to launch a well planned offensive on behalf of Avandia....

In our report, we released a private email that Dr. Buse later sent a colleague detailing this encounter with GSK:

[T]he company’s leadership contact[ed] my chairman and a short and ugly set of interchanges occurred over a period of about a week ending in my having to sign some legal document in which I agreed not to discuss this issue further in public.

Dr. Buse ended the email, “I was certainly intimidated by them.... It makes me embarrassed to have caved in several years ago.”

Multiple media outlets covered Yamada’s actions, including The Guardian (GSK accused of trying to intimidate critic), NBC News (Diabetes drug probe leads to Gates Foundation), and even Bill Gates hometown newspaper, the Seattle Times (Senate committee turns attention to Gates Foundation official).

Months prior to the report’s release, The New York Times also detailed Dr. Yamada’s behavior (Doctor Says He Was Assailed for Challenging Drug’s Safety), as some initial evidence came to light during a hearing in the House. 

In response to all this outcry, Bill Gates did... nothing.

To put this matter directly under Bill Gates’ nose, I then wrote the Senate Committee’s letter demanding that Dr. Yamada come and brief Senate investigators. Just in case Gates was too distracted with saving the world and playing public health saviour to have noticed the bad press, I had the letter sent directly to the Gates Foundation.

When Dr. Yamada showed up for his appointment in Senate Hart, we started with some brief niceties and formalities—typical DC nonsense such as shaking hands, passing out business cards, asking how the plane flight was—before getting down to business. Dr. Yamada’s lawyer then pulled from his briefcase a marked-up copy of a Committee report I had written titled: The Intimidation of Dr. John Buse and the Diabetes Drug Avandia.  

We spent about twenty minutes going over the report, as the lawyer explained what Dr. Yamada had done. He then turned the matter over to Dr. Yamada to detail why, many years prior, he had called Dr. Buse's superiors at the University of North Carolina.

As Dr. Yamada explained, he wasn't trying to intimidate anyone. Ironically, he even offered up the idea that he had called Dr. Buse's dean at North Carolina, because he was concerned that Avandia might actually be harmful. And if the drug was harmful, Dr. Yamada said, he wanted to know.

I almost giggled when he said that.

I then asked, "So this is the only time that you can remember calling a university about one of their faculty?"

"Yes," he replied.

I let him drone on some more, explaining medical research, before I asked him again if he had ever called a university to complain about a professor. Again, he denied doing so, and then started explaining drug development and the regulatory process at the FDA. 

I then asked again, "So during all your time at GSK, this is the only incident you can remember where you placed a call to a university about a researcher who raised concerns about one of your products, correct?” I asked. “It was a singular incident in your time at the company?”

"Yes," he said.

This was the third time that Dr. Yamada had denied making calls to other universities to intimidate academics speaking up about Avandia. I then pulled out copies of GSK emails, showing that Dr. Yamada had called the University of Pennsylvania about physicians there who were worried about drug’s dangers.

“Would you like to explain to us about the call you made to the University of Pennsylvania?” I asked. “One of the physicians involved told me, 'It left a really bad taste in my mouth. After that happened, I said that I would never work for a drug company.’ Another physician who was involved told me, 'It’s the kind of thing you imagine happening on TV.'’’

I then slid the emails across the table to him. Dr. Yamada’s attorney jumped up and grabbed the emails saying, “These emails weren't in the report!”

“No shit, Counselor,” I thought. “I left these ones out, to see if your client might lie to us. Calm down. Everything's going to be A-O-K....”

We then exchanged some more niceties as Yamada “reexplained himself.” Oddly enough, it seems there may have been more than just that one incident at North Carolina, Dr. Yamada said. But I really wasn't interested in listening and started checking my Blackberry.

It took a couple more years to go through hundreds of thousands of GSK’s internal documents before we released our final 342-page report in 2010 titled: Staff Report on GlaxoSmithKline and the Diabetes Drug Avandia. But we redacted the names of the scientists at the University of Pennsylvania who Dr. Yamada had harassed for speaking up, because they were still scared about possible retaliation from the drug industry. 

After reading the report, Yale cardiologist Harlan Krumholz wrote that it "read like a spy novel.” Analysts at UBS predicted that GlaxoSmithKline could face legal liability of up to $6 billion. The New York Times covered the report on its front page and the CBS News put Yamada in its story’s headline: Meet Glaxo's Fixer -- The Man Who Scuttles Drug Critics With One Phone Call.

And still, Bill Gates did nothing.

Five months after the 2010 Senate Finance report, GSK agreed to a $460 million settlement with 10,000 Americans who sued the company for withholding Avandia’s heart attack risks. The New York Times editorialized that GSK and its leaders “can’t be trusted to report adverse clinical results fairly.” 

Nothing at all happened to Yamada. He remained in his role as global health expert at the Gates Foundation, until he left the following year, in June 2011

Keeping someone like Yamada to run a global health program has always made me doubt Bill Gates’ commitment to public health. How could anyone have faith in Gates’ judgement after watching him stand idly by as a stream of evidence proved that one of his top lieutenants had a history of corrupt behavior?

Since that time, I have never trusted Bill Gates. And neither should you.

A natural food supplement may relieve anxiety

Weizmann Institute of Science, May 24, 2021

A natural food supplement reduces anxiety in mice, according to a new Weizmann Institute of Science study. The plant-derived substance, beta-sitosterol, was found to produce this effect both on its own and in synergic combination with an antidepressant known under the brand name Prozac. If these findings, published today in Cell Reports Medicine, are confirmed in clinical trials, they could point the way toward the use of beta-sitosterol as a treatment for relieving anxiety in humans.

Anxiety is not always a bad thing. In fact, in evolutionary terms, feeling anxious about potential threats is critical for survival because it helps us mount an appropriate response. That's precisely why developing antianxiety drugs is so challenging. The circuits for anxiety in the brain are closely related to those responsible for memory, awareness and other functions vital for handling danger, so scientists are on the lookout for compounds that can selectively suppress anxiety without causing unwanted side effects.

The starting point for the present study was research conducted several years ago in the lab of Prof. Mike Fainzilber in Weizmann's Biomolecular Sciences Department. Dr. Nicolas Panayotis and other lab members studied the roles of proteins that shuttle cargoes into the nuclei of nerve cells, and they discovered that in stressful situationsmice lacking a shuttling protein known as importin alpha-five showed less anxiety than the control mice. The researchers then checked how these 'calmer' mice differed from regular ones in terms of gene expression, and they identified a genetic signature of their calmness: about 120 genes with a characteristic pattern of expression in the hippocampus, one of the brain regions that regulate anxiety.

In the new study, Panayotis, now a senior intern in Fainzilber's lab, together with colleagues, searched an international genomic database for existing drugs or other compounds that might mimic the same gene expression signature. He identified five candidates and tested their effects on behavior in mice. That was how the researchers zeroed in on beta-sitosterol, a plant substance sold as a dietary supplement intended mainly to reduce cholesterol levels.

In a series of behavioral experiments, mice given beta-sitosterol showed much less anxiety than the controls. They were, for example, less fearful than the controls when placed in an illuminated enclosure, daring to walk into its brightly lit center, whereas regular mice were careful to stay on the darker periphery, avoiding the stress of the bright light. Moreover, the mice receiving beta-sitosterol did not exhibit any of the side effects that might be expected from antianxiety medications—their locomotion was not impaired, and they did not refrain from exploring novel stimuli.

Next, the researchers tested the effects of beta-sitosterol on mice when given in combination with fluoxetine, a drug belonging to the class of selective serotonin reuptake inhibitors, or SSRIs, and sold under the brand name Prozac, among others. The combination had a synergistic effect: Both beta-sitosterol and fluoxetine reduced the anxiety of mice at lower doses when given together, compared with the doses needed to produce the same effect when they were administered separately.

"One of the major problems with existing antianxiety medications is that they produce side effects, so if beta-sitosterol could help cut down the dosage of such medications, it might potentially also reduce the unwanted side effects," Panayotis says.

A great advantage of beta-sitosterol is that it is naturally present in a variety of edible plants, and it is thought to be safe, as it has been marketed for years as a nutraceutical. It is found in particularly large concentrations in avocados, but also in pistachios, almonds and other nuts, in canola oil, in various grains and cereals and more.

However, this does not mean that eating avocado can induce a calming effect, since it doesn't contain enough beta-sitosterol. "You'd need to eat avocado day and night to get the right dose—and you would be more likely to develop digestive problems than relieve your anxiety," Panayotis says.

The precise mechanism of beta-sitosterol's effect on anxiety remains to be revealed, but the scientists did find that the expression of several genes known to be activated in stressful situations was reduced in mice given the supplement. They also found that these mice had changes in the levels of certain metabolites and neurotransmitters in brain areas involved in anxiety.

Since the study focused on brain regions and neural pathways that are involved in regulating anxiety in both mice and humans, it is likely that the findings will apply to humans as well. This will, however, require further clinical testing.

As Fainzilber points out: "There's a need for a clinical trial to test the use of beta-sitosterol for reducing anxiety in humans. Until then, we recommend that people consult their physicians before taking the supplement for this purpose."

 

Benfotiamine, vitamin B derivative, intake associated with reduced progression of cognitive decline

Weil Cornell Medicine, May 20, 2021

A randomized phase II trial reported in 2020 in the Journal of Alzheimer’s Disease resulted in positive effects among individuals with amnestic mild cognitive impairment or mild Alzheimer’s dementia who were given capsules that contained benfotiamine, a derivative of thiamine (vitamin B1). 

The trial included 70 cognitively impaired men and women who received physical examinations and completed the Mini-Mental Status Exam (MMSE) prior to enrollment. Prospective candidates received positron emission tomography (PET)/CT scans of the brain to confirm the presence of amyloid plaques that are characteristic of Alzheimer disease) and other general blood tests, an electrocardiogram and neurological exam prior to enrollment. Screening tests commonly used to test for diabetes were also performed prior to enrollment, and participants were required to have a hemoglobin A1c (HbA1c) of less than 8% and/or a fasting glucose of less than 200 milligrams per deciliter to be enrolled in the trial.

APOE genotype was determined upon enrollment in the trial. The presence of one or two copies of the APOE4 variant of the APOE gene is associated with a greater risk of Alzheimer disease in comparison with APOE2 or APOE3.

Blood testing conducted at the beginning and end of the trial measured levels of vitamin B1 and advanced glycation end-products (AGEs), which are formed when fats or proteins react with sugar in the blood. (Research suggests that AGEs are predictive of long-term decline in cognition-related daily living performance in Alzheimer disease patients.) Participants also underwent fluorodeoxyglucose positron-emission tomography (FDG PET) at these time points to assess brain glucose utilization which, when reduced, is associated with cognitive decline. Cognitive tests, including the Alzheimer Disease Assessment Scale-Cognitive Subscale, Clinical Dementia Rating and others were administered at the beginning of the study and at varying time points thereafter. Participants received capsules containing 300 milligrams benfotiamine or a placebo twice daily for one year. 

At the end of the treatment period, thiamine levels were significantly elevated in the benfotiamine-intake group. The 12 month increase in Alzheimer Disease Assessment Scale-Cognitive Subscale scores (indicating increased cognitive dysfunction) was lower among those who received benfotiamine compared to the placebo group. Benfotiamine intake participants additionally experienced 77% less deterioration in Clinical Dementia Rating scores compared to the placebo group; however, the effect seen with benfotiamine was stronger among participants who did not have the APOE4 variant. Benfotiamine was also associated with a significant reduction in the increase in AGEs compared to the placebo, which again was stronger in noncarriers of APOE4. FDG PET data suggested that participants without APOE4 were more responsive to benfotiamine intake.

“Benfotiamine is safe and cost effective, and the results of this pilot study are encouraging, providing preliminary evidence of efficacy,” authors Gary E. Gibson of Weil Cornell Medicine and colleagues concluded. “Our next step is to propose a larger clinical trial appropriately powered to replicate our findings. We believe that further studies would be very valuable to determine whether benfotiamine may be helpful in delaying onset or treating Alzheimer disease.”

 

'45 is the new 50' as age for colorectal cancer screening is lowered

Dana Farber Cancer Institute, May 21, 2021

BOSTON - Prompted by a recent alarming rise in cases of colorectal cancer in people younger than 50, an independent expert panel has recommended that individuals of average risk for the disease begin screening exams at 45 years of age instead of the traditional 50. 

The guideline changes by the U.S. Preventive Services Task Force (USPSTF), published in the current issue of JAMA, updates its 2016 recommendations and aligns them with those of the American Cancer Society, which lowered the age for initiation of screening to 45 years in 2018.

Colorectal cancer (CRC) is one of the most preventable malignancies, owing to its long natural history of progression and the availability of screening tests that can intercept and detect the disease early. Overall incidence of CRC in individuals 50 years of age and older has declined steadily since the mid-1980s, largely because of increased screening and changing patterns of modifiable risk factors.

"A concerning increase in colorectal cancer incidence among younger individuals (ie, younger than 50 years; defined as young-onset colorectal cancer) has been documented since the mid-1990s, with 11% of colon cancers and 15% of rectal cancers in 2020 occurring among patients younger than 50 years, compared with 5% and 9%, respectively, in 2010," said Kimmie Ng, MD, MPH, first author of an editorial in JAMA accompanying the article about the guideline change of the USPSTF. Ng is the director of the Young-Onset Colorectal Cancer Center at Dana-Farber Cancer Institute. 

The causes of the increase in young-onset CRC aren't currently known. 

Lowering the recommended age to initiate screening "will make colorectal cancer screening, which is so important, available to millions more people in the United States, and hopefully many more lives will be saved by catching colorectal cancer earlier, as well as by preventing colorectal cancer," said Ng.

The USPSTF is an independent panel of experts funded by the U.S. Department of Health and Human Services. It systematically reviews the evidence of effectiveness of preventive services and develops recommendations. American health insurance groups are required to cover, at no charge to the patient, any service that the USPSTF recommends with a grade A or B level of evidence, regardless of how much it costs.

The task force recommendation means that insurers will be required to cover preventive procedures such as colonoscopies and stool tests designed to detect colon cancer in early stages.

The task force selected age 45 based on research showing that initiating screening at that age averted more early deaths than starting at age 50, with a relatively small increase in the number of colonoscopy complications. There is no change to the USPSTF 2016 recommendation to only selectively screen individuals aged 76 to 85, as research shows only small increases in life-years gained.

The accompanying JAMA editorial asked rhetorically whether the age of screening should be lowered even younger than age 45. While the majority of young-onset CRC diagnoses and deaths occurs in persons 45 to 49, the rate of increase in young-onset CRC is actually steepest in the very youngest patients. Colon cancer incidence is increasing by 2% per year in 20 to 29-year-olds, compared with 1.3% in 40 to 49-year-olds. Rectal cancer incidence is increasing by 3.2% per year in 20 to 29-year-olds and 30 to 39-year-olds, versus 2.3% in 40 to 49-year-olds.

"We are now seeing patients even younger than 45 - in their 20s and 30s - who are being diagnosed with this cancer and often at very late stages," said Ng. "Clearly the USPSTF recommendation to start screening at age 45 will not be enough to catch those young people who are being diagnosed."

Ultimately, optimal prevention and early detection of CRC in people younger than 45 will require further research into the underlying causes and risk factors of young-onset CRC, which have thus far remained elusive, said the editorial authors. 

The authors also called for "bold steps" to translate the lowered age of beginning screening into meaningful decreases in CRC incidence and mortality, noting that despite the preventive benefits of colorectal cancer screening, only 68.8 percent of eligible individuals in the United States undergo screening. The rate is lower among the uninsured and underinsured, those with low incomes, and racial and ethnic minorities. Barriers include lack of knowledge of the importance of screening, concerns about the invasive nature of colonoscopy, and lack of access to and provider recommendations for screening.

The editorial lists examples including public awareness campaigns, including those aimed at gaps in CRC incidence and mortality between Black and white Americans, and specific actions. Employers could provide 45-year-old employees with a paid "wellness day" to undergo CRC screening, or offer day care or transportation vouchers to overcome the logistical hurdles of colonoscopies. Health systems could offer weekend or after-hours appointments for colonoscopies.

The new recommendation "represents an important policy change," the authors wrote, "to drive progress toward reducing colorectal cancer incidence and mortality."

 

 

Study Finds New and Effective Treatment for Vitamin D Deficiency

Boston University School of Medicine, May 20, 2021

There are several million people worldwide with various fat malabsorption syndromes including those who have undergone gastric bypass surgery and those with obesity. These patients often have a difficult time absorbing vitamin D and both groups of patients are at an increased risk for vitamin D deficiency and therefore at higher risk for osteoporosis and osteomalacia (softening of the bones). Patients with obesity are also susceptible to vitamin D deficiency as vitamin D derived from intestinal absorption and cutaneous synthesis is diluted in a larger body pool of fat. Now a new study demonstrates 25-hydroxyvitamin D3 is an effective treatment for vitamin D deficiency for these specific patients.

According to the researchers, approximately one third of adults are obese and require much larger doses of vitamin D to satisfy their requirement. "This vitamin D metabolite is better absorbed in patients with fat malabsorption syndromes and since it is not as fat soluble, it does not gets diluted in the body fat and is effective in raising and maintaining blood levels of 25-hydroxyvitamin D in obese people," explained corresponding author Michael F. Holick, PhD, MD, professor of medicine, physiology and biophysics and molecular medicine at Boston University School of Medicine.

Healthy adults, adults with a fat malabsorption syndrome and obese adults were compared to evaluate if a more water-soluble form of vitamin D3 known as 25-hydroxyvitamin D3 was more effective than the same dose of vitamin D3 in improving their vitamin D status. The researchers observed that compared to healthy adults only about 36 percent of orally ingested vitamin D3 was found in the blood of patients with fat malabsorption syndromes including patients who had gastric bypass surgery. When the same adults ingested 25-hydroxyvitamin D3 the patients with fat malabsorption syndromes were able to absorb it as well as the healthy adults thereby raising their vitamin D status to the same degree. A similar observation was made in the obese subjects compared to the healthy controls. "Therefore using 25-hydroxyvitamin D3 could be a novel approach for treating vitamin D deficiency in patients with fat malabsorption syndromes and obese adults," added Holick.

Vitamin D deficiency not only results in bone loss increasing risk for fracture but causes the painful bone disease osteomalacia. Patients who are vitamin D deficient with osteomalacia have unrelenting achiness in their bones and muscles. Vitamin D deficiency has been associated with an increased risk of many chronic illnesses including multiple sclerosis, type 1 diabetes, heart disease, type 2 diabetes, depression, neurocognitive dysfunction and Alzheimer's disease as well as infectious diseases including COVID.

These findings appear online in the American Journal of Clinical Nutrition.

 

Young teens should only use recreational internet and video games one hour daily

Rutgers University, May 24, 2021

Middle-school aged children who use the internet, social media or video games recreationally for more than an hour each day during the school week have significantly lower grades and test scores, according to a study from the Center for Gambling Studies at Rutgers University-New Brunswick.

The findings appear in the journal Computers in Human Behavior

Researchers say the findings give parents and children a moderate threshold for using entertainment-related technology -- no more than one hour daily on school days and four hours a day on weekends. 

"Interactive technology is widely used to promote children's educational access and achievement," said lead author Vivien (Wen Li) Anthony, an assistant professor at the School of Social Work and research associate at the Rutgers Center for Gambling Studies. "During the COVID-19 pandemic, technology has been essential to facilitating remote learning. At the same time, there is a growing concern that excessive technology use, particularly for entertainment, may adversely affect children's educational development by facilitating undesirable study habits and detracting from time spent on learning activities." 

The researchers, which include Professor Lia Nower of the Rutgers Center for Gambling Studies and a researcher from Renmin University of China, analyzed the China Education Panel Survey data, a national survey of educational needs and outcomes of children in China. Approximately 10,000 first-year middle school students were surveyed and followed. Their average age was 13.5 years.

The results showed that children who used the internet, social media or video games for entertainment four or more hours daily were four times more likely to skip school than those who did not. Boys used interactive technology for entertainment significantly more than girls. Boys also performed worse and showed lower school engagement levels than girls.

"Such findings are critical, particularly in light of the recent movement toward online learning in countries throughout the world," said Anthony. "In a learning environment that integrates the internet, it is easy for children to move across educational and entertainment platforms during learning without alerting teachers or adults to alternate activities."

Anthony said children in the study who used technology in moderation (i.e., less than one hour per day on weekends) experienced less boredom at school, potentially due to the positive effects of participation in social media, video games and video streaming such as peer bonding and relationship building. Using interactive technology for entertainment in moderation advanced children's cognitive development. 

The findings suggest that parents place time limits on their children's interactive technology use, and that parents and teachers should help children to develop effective time management and self-regulation skills to reduce their reliance on technology.

 

Do people aged 105 and over live longer because they have more efficient DNA repair?

University of Bologna (Italy),  May 19, 2021

Researchers have found that people who live beyond 105 years tend to have a unique genetic background that makes their bodies more efficient at repairing DNA, according to a study published in eLife.

This is the first time that people with ‘extreme longevity’ have had their genomes decoded in such detail, providing clues as to why they live so long and manage to avoid age-related diseases.

“Aging is a common risk factor for several chronic diseases and conditions,” explains Paolo Garagnani, Associate Professor at the Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Italy, and a first author of the study. “We chose to study the genetics of a group of people who lived beyond 105 years old and compare them with a group of younger adults from the same area in Italy, as people in this younger age group tend to avoid many age-related diseases and therefore represent the best example of healthy aging.”

Garagnani and colleagues, in collaboration with several research groups in Italy and a research team led by Patrick Descombes at Nestle Research in Lausanne, Switzerland, recruited 81 semi-supercentenarians (those aged 105 years or older) and supercentenarians (those aged 110 years or older) from across the Italian peninsula. They compared these with 36 healthy people matched from the same region who were an average age of 68 years old.

They took blood samples from all the participants and conducted whole-genome sequencing to look for differences in the genes between the older and younger group. They then cross-checked their new results with genetic data from another previously published study which analysed 333 Italian people aged over 100 years old and 358 people aged around 60 years old.

They identified five common genetic changes that were more frequent in the 105+/110+ age groups, between two genes called COA1 and STK17A. When they cross-checked this against the published data, they found the same variants in the people aged over 100. Data acquired from computational analyses predicted that this genetic variability likely modulates the expression of three different genes.

The most frequently seen genetic changes were linked to increased activity of the STK17A gene in some tissues. This gene is involved in three areas important to the health of cells: coordinating the cell’s response to DNA damage, encouraging damaged cells to undergo programmed cell death and managing the amount of dangerous reactive oxygen species within a cell. These are important processes involved in the initiation and growth of many diseases such as cancer.

The most frequent genetic changes are also linked to reduced activity of the COA1 gene in some tissues. This gene is known to be important for the proper crosstalk between the cell nucleus and mitochondria - the energy-production factories in our cells whose dysfunction is a key factor in aging.

Additionally, the same region of the genome is linked to an increased expression of BLVRA in some tissues - a gene that is important to the health of cells due to its role in eliminating dangerous reactive oxygen species.

“Previous studies showed that DNA repair is one of the mechanisms allowing an extended lifespan across species,” says Cristina Giuliani, Senior Assistant Professor at the Laboratory of Molecular Anthropology, Department of Biological, Geological and Environmental Sciences, University of Bologna, and a senior author of the study. “We showed that this is true also within humans, and data suggest that the natural diversity in people reaching the last decades of life are, in part, linked to genetic variability that gives semi-supercentenarians the peculiar capability of efficiently managing cellular damage during their life course.”

The team also measured the number of naturally occurring mutations that people in each age group had accumulated throughout their life. They found that people aged 105+ or 110+ had a much lower burden of mutations in six out of seven genes tested. These individuals appeared to avoid the age-related increase in disruptive mutations, and this may have contributed in protecting them against diseases such as heart disease.

“This study constitutes the first whole-genome sequencing of extreme longevity at high coverage that allowed us to look at both inherited and naturally occurring genetic changes in older people,” says Massimo Delledonne, Full Professor at the University of Verona and a first author of the study.

“Our results suggest that DNA repair mechanisms and a low burden of mutations in specific genes are two central mechanisms that have protected people who have reached extreme longevity from age-related diseases,” concludes senior author Claudio Franceschi, Professor Emeritus of Immunology at the University of Bologna.

 

 

 

Your Risk of Dying Hinges on Well-Being Not Diseases

 

 

University of Chicago, May 18, 2021

A new study has yielded a radically different picture of aging in America, finding that how old you are plays little or no role in determining differences in health and well-being.

The researchers say the results suggest the medical community is focusing on the wrong set of factors to determine risk of dying. Rather than rely on a checklist of infirmities—heart disease, cancer, diabetes, high blood pressure, and cholesterol levels—perhaps it’s time to consider a new “comprehensive model” that looks at factors such as psychological well-being, sensory function, and mobility.

“The new comprehensive model of health identifies constellations of health completely hidden by the medical model and reclassifies about half of the people seen as healthy as having significant vulnerabilities that affect the chances that they may die or become incapacitated within five years,” says Professor Martha McClintock, a biopsychologist and lead author of the study in the Proceedings of the National Academy of Sciences.

“At the same time, some people with chronic disease are revealed as having many strengths that lead to their reclassification as quite healthy, with low risks of death and incapacity,” adds Professor Linda Waite, a demographer and study coauthor.

The study is a major longitudinal survey of a representative sample of 3,000 people between the ages of 57 to 85 conducted by the independent research organization NORC at the University of Chicago.

SOME OF THE FINDINGS INCLUDE:
  • Cancer itself is not related to other conditions that undermine health.
  • Poor mental health, which afflicts one in eight older adults, undermines healthin ways not previously recognized.
  • Obesity seems to pose little risk to older adults with excellent physical and mental health.
  • Sensory function and social participation play critical roles in sustaining or undermining health.
  • Breaking a bone after age 45 is a major marker for future healthissues.
  • Older men and women have different patterns of healthand well-being during aging.
  • Mobility is one of the best markers of well-being.

The comprehensive model reflects a definition of health long advanced, but little studied, by the World Health Organization, which considers health to include psychological, social, and physical factors in addition to the diseases that are the basis for the current medical model of health.

THE HEALTHIEST 22%

Twenty-two percent of older Americans were in the model’s healthiest category. This group was typified by higher obesity and blood pressure, but had fewer organ system diseases, better mobility, sensory function, and psychological health. They had the lowest prevalence of dying or becoming incapacitated (six percent) five years into the study.

A second category had normal weight, low prevalence of cardiovascular disease and diabetes, but had one minor disease such as thyroid disease, peptic ulcers, or anemia. They were twice as likely to have died or become incapacitated within five years.

Two emerging vulnerable classes of health traits, completely overlooked by the medical model, included 28 percent of the older population. One group included people who had broken a bone after age 45. A second new class had mental health problems, in addition to poor sleep patterns, engaged in heavy drinking, had a poor sense of smell, and walked slowly, all of which correlate with depression.

The most vulnerable older people were in two classes—one characterized by immobility and uncontrolled diabetes and hypertension. A majority of people in each of these categories were women, who tend to outlive men.

“From a health system perspective, a shift of attention is needed from disease-focused management, such as medications for hypertension or high cholesterol, to overall well-being across many areas,” says William Dale, associate professor of medicine and a member of the research team.

“Instead of policies focused on reducing obesity as a much lamented health condition, greater support for reducing loneliness among isolated older adults or restoring sensory functions would be more effective in enhancing health and well-being in the older population,” says Edward Laumann, also a collaborator and sociology professor.

Western diet may increase risk of gut inflammation, infection

Diet rich in sugar, fat damages immune cells in digestive tracts of mice

Washington University School of Medicine in St. Louis and Cleveland Clinic

Eating a Western diet impairs the immune system in the gut in ways that could increase risk of infection and inflammatory bowel disease, according to a study from researchers at Washington University School of Medicine in St. Louis and Cleveland Clinic.

The study, in mice and people, showed that a diet high in sugar and fat causes damage to Paneth cells, immune cells in the gut that help keep inflammation in check. When Paneth cells aren't functioning properly, the gut immune system is excessively prone to inflammation, putting people at risk of inflammatory bowel disease and undermining effective control of disease-causing microbes. The findings, published May 18 in Cell Host & Microbe, open up new approaches to regulating gut immunity by restoring normal Paneth cell function.

"Inflammatory bowel disease has historically been a problem primarily in Western countries such as the U.S., but it's becoming more common globally as more and more people adopt Western lifestyles," said lead author Ta-Chiang Liu, MD, PhD, an associate professor of pathology & immunology at Washington University. "Our research showed that long-term consumption of a Western-style diet high in fat and sugar impairs the function of immune cells in the gut in ways that could promote inflammatory bowel disease or increase the risk of intestinal infections."

Paneth cell impairment is a key feature of inflammatory bowel disease. For example, people with Crohn's disease, a kind of inflammatory bowel disease characterized by abdominal pain, diarrhea, anemia and fatigue, often have Paneth cells that have stopped working.

Liu and senior author Thaddeus Stappenbeck, MD, PhD, chair of the Department of Inflammation and Immunity at Cleveland Clinic, set out to find the cause of Paneth cell dysfunction in people. They analyzed a database containing demographic and clinical data on 400 people, including an assessment of each person's Paneth cells. The researchers found that high body mass index (BMI) was associated with Paneth cells that looked abnormal and unhealthy under a microscope. The higher a person's BMI, the worse his or her Paneth cells looked. The association held for healthy adults and people with Crohn's disease.

To better understand this connection, the researchers studied two strains of mice that are genetically predisposed to obesity. Such mice chronically overeat because they carry mutations that prevent them from feeling full even when fed a regular diet. To the researchers' surprise, the obese mice had Paneth cells that looked normal.

In people, obesity is frequently the result of eating a diet rich in fat and sugar. So the scientists fed normal mice a diet in which 40% of the calories came from fat or sugar, similar to the typical Western diet. After two months on this chow, the mice had become obese and their Paneth cells looked decidedly abnormal.

"Obesity wasn't the problem per se," Liu said. "Eating too much of a healthy diet didn't affect the Paneth cells. It was the high-fat, high-sugar diet that was the problem."

The Paneth cells returned to normal when the mice were put back on a healthy mouse diet for four weeks. Whether people who habitually eat a Western diet can improve their gut immunity by changing their diet remains to be seen, Liu said.

"This was a short-term experiment, just eight weeks," Liu said. "In people, obesity doesn't occur overnight or even in eight weeks. People have a suboptimal lifestyle for 20, 30 years before they become obese. It's possible that if you have Western diet for so long, you cross a point of no return and your Paneth cells don't recover even if you change your diet. We'd need to do more research before we can say whether this process is reversible in people."

Further experiments showed that a molecule known as deoxycholic acid, a secondary bile acid formed as a byproduct of the metabolism of gut bacteria, forms the link between a Western diet and Paneth cell dysfunction. The bile acid increases the activity of two immune molecules -- farnesoid X receptor and type 1 interferon -- that inhibit Paneth cell function.

Liu and colleagues now are investigating whether fat or sugar plays the primary role in impairing Paneth cells. They also have begun studying ways to restore normal Paneth cell function and improve gut immunity by targeting the bile acid or the two immune molecules.

 

Glutathione precursor gamma-glutamylcysteine may represent novel strategy for treatment and/or prevention of cognitive impairment

University of New South Wales(Australia), May 12, 2021

According to news originating from Sydney, Australia, research stated, “The accumulation of oxidative stress, neuroinflammation and abnormal aggregation of amyloid beta-peptide (A beta) have been shown to induce synaptic dysfunction and memory deficits in Alzheimer’s disease (AD). Cellular depletion of the major endogenous antioxidant Glutathione (GSH) has been linked to cognitive decline and the development of AD pathology.”

Our news journalists obtained a quote from the research from the University of New South Wales, “Supplementation with gamma-glutamylcysteine (gamma-GC), the immediate precursor and the limiting substrate for GSH biosynthesis, can transiently augment cellular GSH levels by bypassing the regulation of GSH homeostasis. In the present study, we investigated the effect of dietary supplementation of gamma-GC on oxidative stress and A beta pathology in the brains of APP/PS1 mice. The APP/PS1 mice were fed gamma-GC from 3 months of age with biomarkers of apoptosis and cell death, oxidative stress, neuroinflammation and A beta load being assessed at 6 months of age. Our data showed that supplementation with gamma-GC lowered the levels of brain lipid peroxidation, protein carbonyls and apoptosis, increased both total GSH and the glutathione/glutathione disulphide (GSH/GSSG) ratio and replenished ATP and the activities of the antioxidant enzymes (superoxide dismutase (SOD), catalase, glutamine synthetase and glutathione peroxidase (GPX)), the latter being a key regulator of ferroptosis. Brain A beta load was lower and acetylcholinesterase (AChE) activity was markedly improved compared to APP/PS1 mice fed a standard chow diet. Alteration in brain cytokine levels and matrix metalloproteinase enzymes MMP-2 and MMP-9 suggested that gamma-GC may lower inflammation and enhance A beta plaque clearance in vivo. Spatial memory was also improved by gamma-GC as determined using the Morris water maze.”

According to the news editors, the research concluded: “Our data collectively suggested that supplementation with gamma-GC may represent a novel strategy for the treatment and/or prevention of cognitive impairment and neurodegeneration.”

This research has been peer-reviewed.

 

 

Study led by NTU Singapore finds that microbes work as a network in causing lung infection

Nanyang Technological University (Singapore) May 21, 201

Traditionally, an infection is thought to happen when microbes - bacteria, fungi, or viruses - enter and multiply in the body, and its severity is associated with how prevalent the microbes are in the body.

Now, an international research team led by Nanyang Technological University, Singapore (NTU Singapore) has proposed a new way of understanding infections. Their study of close to 400 respiratory samples from patients with bronchiectasis, a chronic lung condition, has shown that microbes in the body exist as a network, and that an infection's severity could be a result of interactions between these microbes.

Through statistical modelling of data from these respiratory samples, the scientists found that flare-ups of coughs and breathlessness (known as exacerbations) occurred more often when there were 'negative interactions' between communities of bacteria, viruses and fungi in the airways. A negative interaction occurs when the microbes compete rather than cooperate with one another.

These findings, published in one of the world's leading scientific journals Nature Medicine in April, bring the scientists one step closer to developing a new way of tackling infections, by targeting microbial interactions rather than the specific microbes.

Assistant Professor Sanjay Haresh Chotirmall from the NTU Lee Kong Chian School of Medicine, who led the study, said: "Our current understanding of infections is that they occur when harmful microbes enter our bodies. This model of understanding, however, fails to account for resident microbes or explain why some patients with infection respond to antibiotics to which the microbe is resistant in laboratory testing. We are therefore proposing that microbes exist as networks, where interactions happen and that the resistant antibiotic in this case targets another microbe with which the culprit is interacting. We therefore can potentially improve clinical outcomes by breaking such crosstalk. 

"The findings of our study are the first steps in providing a more holistic view of how infections occur. While our study looked at patients with bronchiectasis, we believe this concept applies to all forms of infection - whether skin, lung, or a gastrointestinal infection. This way of looking at infections potentially changes our understanding of infection and may offer fresh ways of treating them." 

Associate Professor John Abisheganaden, co-author of the study and Head of Department of Respiratory & Critical Care Medicine at Tan Tock Seng Hospital, said: "By applying an integrated and holistic method, this study provides a new and fresh approach to our understanding of respiratory infection. Applying this precision-medicine approach can help the managing physician better understand and choose the most appropriate antibiotic or other therapy to confer clinical benefit - in short, to guide us to the right treatment at the right time, and for the best outcome."

Microbial interactions and infection 

For their study, the scientists looked at patients with bronchiectasis, a disease of high Asian prevalence, where airways dilate irreversibly and, where infection promotes progression. Targeting bacteria with antibiotics reduces bacterial load and accompanying inflammation, which in turn alleviates symptoms and improves clinical outcomes.

To investigate interactions between microbes in the airways of patients with bronchiectasis, the team collected respiratory (sputum) samples from 383 patients from Singapore, Malaysia, Italy, and Scotland, including samples before, during and after bronchiectasis flare-ups.

After analysing the genetic material from bacteria, fungi and viruses in the samples, the scientists assessed for possible microbial interactions and found that patients with frequent flare-ups had more negative interactions, where microbes compete rather than cooperate, and that the number of such negative interactions increased even further during a flare-up. While changes to interactions between microbes during flare-ups was detected, there was surprisingly minimal change to the type and quantity of microbes present during a flare-up, and even after antibiotics were administered. 

New treatment possibilities

The scientists believe that these findings suggest that microbial interactions potentially drive frequent flare-ups in patients.

Using these findings, the scientists have developed an online tool to help other researchers and physicians analyse microbial interactions in their own patient samples through the microbes' genetic sequences. 

Asst Prof Chotirmall, who is also NTU Provost's Chair in Molecular Medicine, said: "We are proposing a fresh way to view infection, as networks rather than individual microbes. Targeting microbial interactions within an established network may promote more judicious antibiotic use and help curb rising antimicrobial resistance."

The team is currently exploring the use of probiotics to treat bronchiectasis by regulating microbiomes within the air passages.

 

 

Pea flour helps malnourished children regain weight and restores gut flora

Imperial College London, May 21, 201

Adding pea flour to foods for severely malnourished children helps them gain weight and restores the balance of microbes in their gut.

In a small study of severely malnourished children in Uganda, researchers found that providing them with a mix containing cowpea flour improved their ability to absorb nutrients and gain weight, while maintaining their gut microbiome comparable to healthy children.

According to the researchers, the findings, published today in the journal Cell Reports Medicine, lay the foundations for larger trials with cowpea-based supplements and highlight the critical role of gut health in restoring nutrition in children with severe acute malnutrition.

Acute malnutrition is a major contributor to child mortality around the world. It remains a leading cause of death in children under five years of age and increases their risk of life-threatening events such as pneumonia, diarrheal disease or infections. Children with severe acute malnutrition can be treated with nutrient-rich, milk-based formulas to restore weight and nutrition, but despite treatment many will later go on to die.

Professor Gary Frost, head of the Center for Translational Nutrition and Food Research at Imperial College London, said: "These are children who have been admitted to hospital and often have other disease, such as bacterial sepsis, which complicates the picture—so they are very fragile.

"High quality feeds are lifesaving for many thousands of children. But sadly, when children are severely malnourished they can struggle to absorb nutrients and despite initial improvements in hospital, many remain very weak and will later go on to die."

"We have been able to show that legume-enriched feeds are well tolerated by these very sick children, and they may also protect their 'good' gut microbes, compared to traditional feeds. Our hope is that this kind of intervention will help them to grow stronger by enabling their bodies to absorb more of the nutrients from the feed."

More than 'calories in'

Researchers at Imperial College London have been exploring the links between gut health and nutrition, with the aim of improving outcomes for severely malnourished children. Growing evidence suggests that gut microbes feed on carbohydrates from our diet, releasing nutrients which maintain the lining of the gut. Without this regular supply of nutrients, the gut lining deteriorates and becomes 'leaky," reducing our ability to absorb nutrients and increasing the risk of bugs entering the bloodstream where they can cause infection.

Previous research by the Imperial team has shown that increasing dietary fiber can help to overcome this 'leaky gut' syndrome and improve the absorption of nutrients, so they designed and tested a new feed fortified with cowpea—which contains a source of easily fermentable carbohydrates and fiber, both known to be key in maintaining gut health.

In a small proof of concept trial, researchers recruited 58 hospitalized children in Uganda with severe acute malnutrition to receive one of three feeds: a conventional feed; a feed containing the plant compound inulin; and a feed fortified with cowpea flour. Children in all three groups received antibiotics and other medical treatments, as needed, in addition to the feed.

Led by Ph.D. candidates Nuala Calder and Kevin Walsh, the team measured changes to weight after seven days of treatment, along with fecal sampling to look at changes to the makeup of their gut microbiome. The children were also followed up at 28 days.

The researchers found that overall, all feeds resulted in comparable weight gain after one week, and duration of hospital stay did not vary between groups. However, the cowpea feed limited the damage to gut microbes associated with antibiotic treatment—which can reduce the richness of the microbiome by killing off key groups of bugs. The same effect was not seen in conventional feeds or those enriched with inulin—a compound derived from plants—highlighting the role of fiber and other elements in the legume feed.

Following 28 days, there was limited difference in mortality between the groups, and sadly, despite treatment 12 children died (3, 6 and 3 from the respective groups). But analysis suggested that across the groups, children that died had higher levels of gut dysfunction and altered levels of short chain fatty acids, indicating reduced diversity of gut microbes.

Protecting gut bugs

Professor Frost said: "Our major finding was that the cowpea enriched feeds actually protect the gut bugs when these children are given antibiotics, so we know that the feed is actually helping the microbiota to survive some of the concurrent medical therapy these children are receiving.

"We also found that the children that died tended to have a worse gut problem than those who survived, so it has highlighted that the gut is very important in rescuing children from severe malnutrition. These legume enriched feeds may be a small step towards improving outcomes for those children."

Professor Kathryn Maitland, Professor of Tropical Pediatric Infectious Disease at Imperial and based in Kenya, said: "This is a very small study, but it's an important first step. The role the gut actively plays in the pathology of severe malnutrition has not been fully appreciated, and there are multiple parameters that need fixing. Fortifying feeds with legumes can go some way towards that. Many of these children may receive multiple antibiotics, which kills the microbiota, leaving only the microbes that are bad for human health, and these legume enriched feeds may actually help to resist that."

Future trials are now planned to test the legume-enriched feeds in larger numbers of children with severe acute malnutrition in more regions. The team believes that if the feeds could be produced regionally, using legumes such as cowpea which can be grown and milled in East Africa, it could help to reduce the dependency on internationally produced feeds which may be more expensive and less effective.

Professor Maitland added: "Many feeds which are imported to East Africa are based on cow's milk, or a dried form of it. They can contain a lot of sugars, such as sucrose and lactose, and these children can't absorb this. In fact, quite a lot of these malnourished children may develop severe diarrhea from these feeds as they are lacking the enzymes to properly digest and absorb them, so our next steps are to tackle that as well.

"We think that the next iterations of our feed will include legumes, but will also not include any aspect of cow's milk, replacing the sucrose with other carbohydrate sources. This also means that they can be produced locally."

Professor Frost added: "We know that we can reverse the malnutrition, but this isn't really fixing the whole problem. This approach is a radical change for these children. It's taking a very different view of feeding. It's not just about the nutrients flowing in, it's about how compounds in plants are metabolized, and underlying gut health."

 

 

Why blueberries are an effective weapon in the war against Alzheimer’s disease

 

University of Cincinnati,  May 21, 2021 

 

Could a plump, little blueberry really hold colossal promise in the fight against Alzheimer’s disease?  New research adds to the growing evidence that blueberries, bursting with antioxidants, could help diminish the devastating defects of dementia.

Blueberries are already known as a “super fruit,” thanks to their documented contribution to lowering the risk of heart disease and cancer. But now, newly released study findings show that certain flavonoids found in blueberries could also hold the key to lessening the effects of Alzheimer’s disease.

 

Over 5 million Americans suffer from Alzheimer’s disease, a number that is expected to continue to rise as the population ages. The Alzheimer’s Association estimates that as many as 7 million could fall prey to the disease by 2025, and that the number could triple by 2050.  In fact, Alzheimer’s has become the sixth leading cause of death in the United States, with one out of every three elderly persons dying of complications from Alzheimer’s or some other form of dementia.

 

But Alzheimer’s takes a toll on more than just human life. It is an extremely costly disease as well. Experts estimate that Alzheimer’s will cost the nation $236 million and that caregivers will spend more than $5,000 a year trying to care for their loved one.

Hope for Alzheimer’s disease patients: Blueberries found to improve cognition and memory

As scientists work to slow this alarming trend, researchers out of the University of Cincinnati Academic Health Center have released promising results of two human studies conducted in follow up to their earlier clinical trials. Lead author Robert Krikorian, Ph.D., stated that the new findings corroborate those from previous human and animal research.

 

The researchers, led by Krikorian, believe that blueberries’ beneficial effects against Alzheimer’s could be due to certain flavonoids found in the berries. Known as anthocyanins, they have been shown to improve cognition in tests with animals.

 

In one study, 47 adults, aged 68 and older, exhibiting mild cognitive impairment – a risk factor for Alzheimer’s disease – were given either freeze-dried blueberry powder or a placebo powder once a day for 16 weeks. The blueberry powder was equivalent to one cup of fresh blueberries.

 

Those receiving the blueberry powder were found to exhibit improved brain function and cognitive performance compared to those in the control group, with better memory and improved access to words and concepts.  In another study, 94 people, aged 62 to 80, were divided into four groups. The subjects did not have diagnosed early-onset Alzheimer’s, but did report feelings of having their memory decline.

In the trial, stated above (with 94 people), cognition was somewhat better for those consuming powder or fish oil only, but there was little improvement with memory. Also, researchers report that the MRI results were not as definitive for those receiving blueberry powder.

Even with somewhat less striking results from the second study, the scientists believe the two studies show that blueberries may be more effective in treating patients with cognitive impairments. Next up, the researchers want to conduct a study involving younger subjects, all with risk factors for Alzheimer’s.

 

Reaping the benefits of blueberries from your regular diet can be easy. Blueberries are an extremely popular berry and can be found in many stores (and farmers’ markets) throughout the world.  Naturally, to avoid excess consumption of chemicals, it’s best to eat organic varieties only.

 

As a matter of convenience and potency, the best way to incorporate blueberries into your diet is through a powder of pure (organic) blueberry extract or by eating whole, organic berries.  Baking or cooking blueberries will diminish the nutritional value of this powerful fruit.

 

 

 

Oxidative Stress, Vitamin D Deficiency and Male Infertility: An Under-Looked Aspect

 

Aga Khan University (Pakistan), May 21, 2021

Infertility is a known source of distress among couples worldwide. This agony significantly stems from the concern of not having an identifiable cause leading to infertility. With male factors accounting for 20-30% of the total causes of infertility (1), a thorough evaluation of both the partners is done.

Upon evaluation, Vitamin D deficiency was noticed significantly in males coming to infertility centres. However, its functions and how it impacted reproduction was not known until the research led to the discovery of Vitamin D Receptor (VDR) in many organs of the male reproductive tract. It is now known that vitamin D deficiency decreases male fertility by contributing to oxidative stress and gonadal insufficiency, disrupting spermatogenesis, affecting sperm morphology and normal calcium haemostasis. (2)

Oxidative stress, caused by an imbalance between oxidative and antioxidative mechanisms, is believed to be a well-known mechanism underlying idiopathic male infertility. Reproductive health professionals and researchers fittingly started searching for antioxidants to combat this imbalance. A study concluded that adding vitamin D to a cryopreserved semen sample reduced oxidative stress and resulted in better fertility outcomes (3). Animal trials have shown that Vitamin D supplementation reduced oxidative stress and improved semen DNA integrity (4).

As Vitamin D exerts its effects by binding to Vitamin D receptors, it was noted that vitamin D receptor null mutant mice had a significant reduction in successful reproductive outcomes due to gonadal insufficiencies. Reduced levels of oestrogen and testosterone were seen along with low sperm count, reduced motility, abnormal spermatogenesis and histological abnormalities in testes of mutant mice. These insufficiencies were attributed to a decreased CYP2R1, CYP27B1 and CYP24A1 expression, lower aromatase activity, secondary to suppression of CYP19 gene and calcium supplementation improved fertility in such cases. (5)

There is limited human data available on how Vitamin D deficiency causes gonadal insufficiency, which is important to maintain normal reproductive physiology. More studied are needed to clarify the role of vitamin D in gonadal physiology. Considering the importance of Vitamin D on reproductive functions, its role in causing Oxidative stress and gonadal dysfunction, we suggest randomized control trials in pre-pubertal phase.

 

 

Want to escape Alzheimer's disease? Run for your life and exercise

Tel Aviv Sourasky Medical Center (Israel), May 20, 2021



Exercise slows down aging of the brain and can reduce risks of Alzheimer's disease and other dementias by about half.







There is a growing amount of medical evidence that exercise slows down the aging of the brain and can reduce the risk of Alzheimer's disease and other dementias by about half, according to Prof. Nir Giladi, chief of neurology at Tel Aviv Sourasky Medical Center.


He said that the modern sedentary way of life reduces the amount of body movement. Long-term epidemiological and physical studies show that exercise can improve memory, concentration and mood and minimize pain, as well as reduce the risk of cognitive damage, stroke, Parkinson's disease and depression.


The connection between exercise and brain function was first disclosed from animal studies two decades ago, said Giladi. Brains of rats that ran on a wheel for three months at a time had many more neurons and synapses through which electric signals connect. Exercise causes these to multiply, said Giladi.


"These findings flew in the face of the belief that over the age of 30, the neurons decline irreversibly. Today we know that the adult brain has many stem cells that when stimulated can differentiate and turn into ripe neurons that know how to create synapses." The neurologist added that for some unknown reason, the best potential for differentiation exists in brain regions responsible for memory.


Exercise promotes the secretion of trophic factors -- including brain-derived neurotrophic factor that encourage the growth of stem cells that turn into adult nerve cells. he added. These factors activate genes responsible for the development of stem cells in the hippocampus and other brain regions involved in memory, storage and processing of data. They are available in large quantities during a baby's first years when the brain develops at a rapid pace, but the amounts decline during adolescence and aging.


The greater the amount, the more the brain grows and holds more nerve cells, especially in the hippocampus, he said. Exerting the muscles activates unique genes that encourage the muscle cells and apparently others to create proteins that increase the synthesis of trophic factors. "This is why those who exercise regularly look and have younger brain function -- and their cells are more protected from diseases, trauma and natural aging."


Giladi said it was best to do aerobic exercise (causing the heart and lungs to exert themselves) along with non-aerobic exercise (strengthening the muscles on the skeleton) at least three times a week. Even if you exercise just as an adult and the cognitive decline has begun, your physical activity will slow down the rate of decline.


A study published in the journal PNAS  using MRI to see the effect of regular exercise on the brain showed that the brains of healthy 75-year-olds who performed physical activity at least three times a week declined slower in the regions of memory, concentration, planning, initiative and management abilities. The same thing was noted in studies of teenagers, Giladi said. Exercise influences the brain cell in deciding which genes will function and contribute to this and which will be neutralized. This is thus epigenetics, in which the environment actually affects the genes, the neurologist said.


Exercise also increases the supply of blood to the organs, including the brain, he continued, and encourages the growth of alternate blood vessels to take over functions from clogged vessels.


He bemoaned the fact that many Israelis don't exercise regularly. An average of 150 to 300 minutes per week -- half aerobic and half non-aerobic -- can improve the abilities of the brain and protect it from disease, Giladi concluded.

Diabetics who received 1 g of vitamin C daily showed improvements in blood pressure, oxidative stress

Khon Kaen University (Thailand), May 21, 2021

Findings from a randomized, double-blind, cross-over trial reported on February 25, 2021 in the Chinese Journal of Physiology revealed an association between intake of vitamin C and a reduction in blood pressure before and after exercise among men and women with type 2 diabetes. “During exercise, mechanical stress on the arterial wall is increased, leading to an increased release of vasodilators by the endothelium (e.g., nitric oxide, bradykinin, etc.),” explained authors C. Boonthongkaew and colleagues at Khon Kaen University in Thailand. “This response can attenuate blood pressure (BP) after acute exercise at low, moderate, and high intensity in normotensive individuals. However, the magnitude of this effect seems to decline in type 2 diabetes patients because of endothelial dysfunction.”

The trial included 24 type 2 diabetics with poorly controlled disease who received 1,000 milligrams vitamin C or a placebo daily for six weeks, followed by a six-week washout period, followed by six weeks of the alternate intervention. For inclusion in the study, participants were required to have a blood pressure of ≤140/90 mmHg or less, maintained if necessary with antihypertensive treatment. 

Twenty-minute low-intensity exercise sessions were conducted on the day before and the last day of each treatment period. Blood pressure was measured before, immediately after and 60 minutes after the exercise sessions. Blood samples collected before and after exercise were analyzed for plasma vitamin C levels, markers of lipid peroxidation and nitric oxide concentration. 

Compared to pre-intake, participants who received vitamin C experienced an average 12.8 mmHg reduction in systolic BP and an 8.9 mmHg reduction in diastolic BP when at rest before exercise. Immediately after exercise, systolic and diastolic BP were lower by 11.4 mmHg and 6.8 mmHg, and an hour after exercise, systolic and diastolic BP were lower by 12.5 mmHg and 8.9 mmHg in the vitamin C group compared to baseline values. No significant differences between pre- and post-treatment measurements occurred in the placebo group. When compared to the placebo, participants who received vitamin C also had lower systolic and diastolic BP before and after the post-supplementation exercise sessions. 

Post-intake, plasma vitamin C and nitric oxide levels were higher, and markers of lipid peroxidation were lower among vitamin C patients before and immediately after exercise compared to baseline, while the placebo group experienced no significant changes. And when compared to the placebo, vitamin C and nitric oxide were higher and lipid peroxidation markers were lower before and after the exercise session among participants who had received the vitamin.

In their discussion of the findings, the authors remarked that vitamin C’s ability to decrease oxidative stress helps prevent nitric oxide from being degraded by free radicals, which results in higher nitric oxide levels that benefit endothelial function and BP. They announced that the study is the first to report the effect of vitamin C compared to a placebo on BP before and within an hour after exercise. “This study suggests that 6‑week vitamin C [intake] decreased pre-exercise and postexercise blood pressures, possibly due to improved oxidative stress and nitric oxide release,” they concluded.

 
 
 

Making mindfulness meditation more helpful starts with understanding how it can be harmful

Brown University, May 18, 2021

Mindfulness-based meditation programs have emerged as a promising treatment for conditions ranging from stress to sleeplessness to depression. In some cases, they're even offered to people—schoolkids or employees, for example—who aren't actively seeking help or who haven't been screened for suitability. Yet most research and discourse about these programs focuses only on their benefits, with little investigation of the risks or the potential for adverse effects.

A recent review of nearly 7,000 studies of meditation practices found that less than 1% of them measured adverse effects. Willoughby Britton, an associate professor of psychiatry and human behavior at Brown University, said that this is largely because assessing adverse effects (a process known as "harms monitoring") in non-pharmacological treatments like mindfulness-based meditation programs is difficult to do well.

To address that gap, Britton conducted a new study on adverse effects in mindfulness-based programs that identified common obstacles to harms monitoring and, importantly, showed how to address them. The study also found that the rates of adverse effects from mindfulness were similar to those found in other psychological treatments.

The study was published on May 18 in Clinical Psychological Science.

"Our ultimate goal is to maximize the efficacy of mindfulness-based meditation while minimizing harms," said Britton, who directs the Clinical and Affective Neuroscience Laboratory at Brown. "In order to address risks and modify treatment accordingly, you need thorough and detailed knowledge about potential harms. Our study, the most comprehensive of its kind, provides a blueprint for how to accurately assess the risks of mindfulness-based meditation programs."

Why no one wants to talk about meditation's adverse effects

The adverse effects of mindfulness-based meditation programs are often an unpleasant topic for providers and participants alike, Britton said. For the study, she and her colleagues reviewed the most current harms monitoring best practices from regulatory agencies like the World Health Organization, the National Institutes of Health and the U.S. Food and Drug Administration. In the paper, they outlined the key considerations around assessing adverse effects, including hesitancy of participants to report negative reactions to treatment because of feelings of shame or a desire to please the researcher or instructor.

Researchers and mindfulness teachers (Britton is both) are understandably more focused on the help they can provide than any harm they could cause. As a result, a lack of negative feedback from participants is often interpreted as evidence of absence of harm. "It's very easy for our enthusiasm and desire to help to become a kind of blindness," Britton explained.

Another complicating factor, she said, is the lack of knowledge of proper harms assessment.

"Often the mindfulness teacher will ask the class, 'Did anyone have any challenges with your meditation practice this week?'" Britton said. "But participants, in general, tend to avoid answering open-ended questions asked by the teacher in a public setting. Research has shown that having someone other than the teacher ask specific questions in a private setting will increase the likelihood of honest reporting."

Finally, she highlighted the fact that term "adverse" is a highly subjective judgment that can vary across people and even across the same person in different contexts.

"The re-living of a previous trauma may be healing for some and destabilizing for others, in the same way that the drowsiness caused by cold medicine—or meditation—may be undesirable or 'adverse' in the morning but highly desirable before bed," she said. What's more, Britton added, the literature shows that mental health treatment providers (like therapists or doctors) may dismiss patient complaints or reframe them as a sign that the therapy is working.

Designing a model assessment

Britton's research team followed 24 current harms monitoring guidelines to assess the nature and frequency of meditation-related adverse effects in mindfulness-based programs. The study participants were representative of typical meditators in the U.S.: predominantly middle-age women seeking methods to self-manage mild to severe levels of anxiety, depression and stress. After completing one of three versions of an eight-week mindfulness meditation program, participants were interviewed by a researcher unaffiliated with the treatment about their experiences, with 44 questions based on previous research of meditation-related challenges.

To more accurately and thoroughly capture patient perspectives, this study allowed each participant to evaluate the emotional tone or "valence" of each of 44 meditation-related experiences as well as the impact it had on their life and functioning. By asking participants specific questions about duration and impact, researchers were able to differentiate temporary distress, negative-impact side effects and "lasting bad effects." In this way, the researchers sought to clarify which effects were experienced as "adverse" on a case-by-case basis.

To accommodate the varying definitions of harm, results were reported in tiers of severity ranging from "transient distress during meditation" (i.e., temporary) to "enduring impairment in functioning"—or "lasting bad effects."

The "what" is as important as the "how"

The significance of the study, Britton said, has as much to do with what it found as how it found it.

"The fact that meditation can cause altered states, for example, isn't news: It's something that people have been talking about for centuries," Britton said. "What we haven't been very good about is measuring the impact and significance of these states on individual participants."

Of the 96 participants, 58% reported at least one meditation-related adverse effect, which ranged from perpetual hypersensitivity to nightmares to traumatic re-experiencing. Meditation-related adverse effects with negative impacts on functioning occurred in 37% of the sample. Six percent of the sample had "lasting bad effects," or impairments in functioning lasting more than one month. Notably, the researchers say, this rate is similar to those of other psychological treatments.

In the study, meditation-related effects with negative impacts tended to be associated with signs of what's called dysregulated arousal—for example, the participants reported feeling anxious, hyper-stimulated or emotionally flat or disconnected after meditating.

This is important for instructors and participants to note, Britton said, because unlike the experiences of anxiety or insomnia, a feeling of being dissociated or emotionally checked-out is not always experienced as unpleasant and can provide some relief, especially for a person suffering from intense anxiety. Yet in the study, this feeling of dissociation tended to predict more significant and lasting impairment in functioning.

"This is where the differentiation between valence and impact becomes important, because the valence, or emotional tone, of an experience might be not particularly distressing at the time," Britton said. "Meditators are often taught to reappraise their experience as not being problematic, and to accept it for what it is. Our results are basically saying that when it comes to dissociation, this approach isn't going to work."

Britton and colleagues also found that the open-ended question "Have you had any unexpected, unpleasant, adverse or challenging experiences as a result of mindfulness meditation practice during or following the program?" underestimated the true rate by 70%, confirming the inadequacy of open-ended questions compared to specific ones.

The study concludes that the active ingredient of these therapeutic programs, which is mindfulness meditation practice, can be associated with both transient distress and enduring negative impacts on life and functioning. Britton said that it is important to note that adverse effects and benefits are not mutually exclusive: many of the same participants who reported adverse effects also reported improvements in depression.

Britton noted that the intent of the study, as well as of her broader research, is not to discourage mindfulness-based meditation programs—rather, it is to generate findings on both the positive and negative effects so that providers and meditators can make informed decisions.

She compared mindfulness to aspirin, as an example. This medicine-cabinet staple can cause nausea, heartburn and stomach cramps—and taking a daily aspirin can cause gastrointestinal bleeding in some people. But these potential adverse effects do not take away from aspirin's many benefits. Instead, detailed knowledge about the benefits and risks allows practitioners to make educated, effective and safe recommendations to specific patients.

"That's where we need to get with mindfulness, too," Britton said. "Our study is an attempt to bring harms monitoring up to the standards of other treatments so that providers can identify events that require monitoring and intervention in order to maximize the safety and efficacy of mindfulness-based meditation."

 

Vitamin B6, vitamin D and green tea compound could improve uterine fibroids

Sandro Pertini Hospital (Italy), May 19, 2021

In an article whose title asks the question, “Uterine fibroids treatment: do we have new valid alternative?” findings from researchers from Sandro Pertini Hospital in Rome suggest the answer may be “yes.”

The article, published in the April 2021 issue of the European Review for Medical and Pharmacological Sciences reported a benefit for intake of vitamin B6, vitamin D and epigallocatechin gallate (EGCG, a flavonoid that occurs in green tea) in women with uterine fibroids (myomas), benign tumors of the uterus that affect a significant percentage of reproductive-aged women. Uterine fibroids adversely impact fertility, and unfortunately, there are few treatment options for women who desire to become pregnant.

The study included 95 women who had between one and five fibroids. Forty-one participants received 5 milligrams (mg) vitamin B6, 25 micrograms (1,000 international units) vitamin D and 150 mg EGCG twice daily for four months, while a control group of 54 women were monitored without receiving the vitamin B6, vitamin D and EGCG. The number and volume of fibroids was measured using ultrasound before and after the treatment period. Fibroid vascularization was measured by color flow Doppler ultrasound, which color codes blood flow to indicate the direction of flow and/or the presence of high blood turbulence. Other factors assessed at these time points included the presence of heavy bleeding, pelvic pain and health/quality of life. Overall improvement was assessed by a questionnaire, the Patient Global Impression of Improvement (PGI-I), administered to participants who completed the four-month study.

After four months, total fibroid volume significantly decreased by 37.9% among participants who received vitamins B6 and D, plus ECGC, while increasing by 5.5% among women who did not receive the nutrients. Similar results were observed in a subgroup of participants who were smokers – fibroid volume was significantly reduced with the supplement combination. 

Doppler visualization of blood flow to the myomas suggested reduced vascularization in the intervention group and increased vascularization in the control group. Pelvic pain and health, including the participants’ all-over impressions of improvement, significantly improved in comparison with pretreatment levels in the group that received the nutrients while no change occurred in the control group. Specifically, 85.4% of women taking the supplement reported improvements in their PGI-I score, with 73.2% reporting their symptoms were “very much better”.  No side effects were reported. 

Authors Donatella Miriello and colleagues concluded that the study’s findings “showed the effectiveness and safety of a 4-month oral [intake of] a combination of vitamin D, EGCG and vitamin B6 in reducing uterine fibroids’ volume and improving the quality of life of childbearing women. Thus, this…may represent a valid alternative to the classic ‘wait and see’ approach and, at the same time, an adjuvant treatment that could be administered along with pharmacological therapies, even before surgery to reduce the occurrence of possible complications.”

 

 

 

Nitrate-Rich Vegetables Increase Plasma Nitrate and Nitrite Concentrations and Lower Blood Pressure in Healthy Adults

Maastricht University (Netherlands), May 21, 2021

 

Background: Dietary nitrate is receiving increased attention due to its reported ergogenic and cardioprotective properties. The extent to which ingestion of various nitrate-rich vegetables increases postprandial plasma nitrate and nitrite concentrations and lowers blood pressure is currently unknown.

 

Objective: We aimed to assess the impact of ingesting different nitrate-rich vegetables on subsequent plasma nitrate and nitrite concentrations and resting blood pressure in healthy normotensive individuals.

 

Methods: With the use of a semirandomized crossover design, 11 men and 7 women [mean ± SEM age: 28 ± 1 y; mean ± SEM body mass index (BMI, in kg/m2): 23 ± 1; exercise: 1–10 h/wk] ingested 4 different beverages, each containing 800 mg (∼12.9 mmol) nitrate: sodium nitrate (NaNO3), concentrated beetroot juice, a rocket salad beverage, and a spinach beverage. Plasma nitrate and nitrite concentrations and blood pressure were determined before and up to 300 min after beverage ingestion. Data were analyzed using repeated-measures ANOVA.

Results: Plasma nitrate and nitrite concentrations increased after ingestion of all 4 beverages (P < 0.001). Peak plasma nitrate concentrations were similar for all treatments (all values presented as means ± SEMs: NaNO3: 583 ± 29 μmol/L; beetroot juice: 597 ± 23 μmol/L; rocket salad beverage: 584 ± 24 μmol/L; spinach beverage: 584 ± 23 μmol/L). Peak plasma nitrite concentrations were different between treatments (NaNO3: 580 ± 58 nmol/L; beetroot juice: 557 ± 57 nmol/L; rocket salad beverage: 643 ± 63 nmol/L; spinach beverage: 980 ± 160 nmol/L; P = 0.016). When compared with baseline, systolic blood pressure declined 150 min after ingestion of beetroot juice (from 118 ± 2 to 113 ± 2 mm Hg; P < 0.001) and rocket salad beverage (from 122 ± 3 to 116 ± 2 mm Hg; P = 0.007) and 300 min after ingestion of spinach beverage (from 118 ± 2 to 111 ± 3 mm Hg; P < 0.001), but did not change with NaNO3. Diastolic blood pressure declined 150 min after ingestion of all beverages (P < 0.05) and remained lower at 300 min after ingestion of rocket salad (P = 0.045) and spinach (P = 0.001) beverages.

 

Conclusions: Ingestion of nitrate-rich beetroot juice, rocket salad beverage, and spinach beverage effectively increases plasma nitrate and nitrite concentrations and lowers blood pressure to a greater extent than sodium nitrate. These findings show that nitrate-rich vegetables can be used as dietary nitrate supplements.

 
 
 

High-intensity interval training improves spatial memory in rats

 

University of Tsukuba (Japan), May 17, 2021

Researchers at the University of Tsukuba have found that, despite only covering about one-third of the distance in HIIT compared with that covered in endurance training, similar improvements in exercise capacity and brain function were observed for both forms of exercise.

"We investigated how rats' muscles and brains—specifically, the region of the brain involved in spatial learning called the hippocampus—adapted to these types of exercise, and how the rats consequently learned and remembered navigating mazes," explains Professor Hideaki Soya, the principal investigator.

In the experiment, rats were assigned to one of three groups—resting, endurance running, or alternating intervals (short sprints and rest)—during training sessions on treadmills five days/week for four weeks.

Both endurance running and HIIT resulted in weight loss, greater muscle mass, and the ability to exercise longer compared with controls; however, increased cellular aerobic capacity was found in the soleus (a muscle with predominantly slow-twitch fibers that makes it functionally well suited to endurance) and in the plantaris (a muscle with predominantly fast-twitch fibers for meeting high-energy functional demands) in the endurance-running and HIIT groups, respectively.

Rats in both groups demonstrated better memory of spatial learning trials in searching for an escape platform in a water maze. In the hippocampus, increased cell development—neurogenesis—was also observed for both forms of exercise; however, levels of a signaling protein that promotes neurogenesis (BDNF) were increased by HIIT but not by endurance running, whereas the levels of its receptor (TrkB) were increased by both.

Given that BDNF expression is known to be affected by exercise, why didn't endurance running increase BDNF expression? The answer may lie in the mediating role of stress on BDNF expression; exercise is a type of stress. While stress indicators in both exercise groups were found to be similar, this line of enquiry may lead to future studies:

"In this study, we showed that an HIIT exercise regimen with a low exercise volume nevertheless improves spatial memory, and we demonstrated that these improvements are supported by changes in neuronal plasticity in the hippocampus. In a previous study, we found that continuous light-intensity training had a similar beneficial effect, whereas continuous high-intensity training did not," Professor Soya summarizes. "Thus, it seems that the benefits yielded by exercise may actually depend on optimization, that is, a trade-off between exercise time and intensity."

A future where exercise regimens can be tailored to improve both physical and cognitive features may be on the horizon.

 

Hygiene rules are also effective against new coronavirus variants

Ruhr-University Bochum (Germany), May 21, 2021

The researchers found that the variants have a similar surface stability as the wild type virus under laboratory conditions, but can be effectively eliminated by disinfection and thorough hand washing, heat or alcohol treatment. They report their results in the Journal of Infectious Diseases from 16 May 2021.

For this study, the team from the Department for Molecular and Medical Virology and the Chair of Materials Discovery and Interfaces at Ruhr-Universität Bochum (RUB) cooperated with the European Virus Bioinformatics Center Jena, the University Hospital Duisburg-Essen and Paracelsus Medical University Nuremberg.

The fact that viruses change genetically over time is well known. Variants of concern are those that give the virus an advantage, for example by allowing it to replicate faster, become more infectious or enable it to evade the immune response. The British and South African variants have accumulated several mutations which result in an increased transmission and, in some cases, lead to more severe courses of disease. "Therefore, the question arose whether they also differ from the original variant in terms of their sensitivity to hygiene measures," explains Toni Meister from Ruhr-Universität Bochum.

Heat, soap, alcohol

For this reason, the team analysed how long the variants remain infectious on surfaces made of steel, silver, copper and on face masks and how they can be rendered harmless by means of soap, heat or alcohol.

It turned out that both variants, as well as the wild type virus, could be inactivated when treated with at least 30 percent alcohol for at least 30 seconds. "Common disinfectants are therefore effective against all these variants," says Stephanie Pfänder from RUB. Thorough hand washing with soap could also lower the risk of infection. Heat also works against the virus: after 30 minutes at 56 degrees Celsius, all variants were rendered harmless.

To find out whether the stability of the different mutant variants on surfaces differs from each other, they analyzed the amount of infectious virus particles on surfaces made of steel, copper, silver and on surgical and FFP2 masks over 48 hours. "The surface stability did not differ between the virus variants," points out Eike Steinmann from the Department for Molecular and Medical Virology at RUB. "As described several times before, copper in particular has a very strong antiviral effect". In conclusion, the team did not detect any differences between the different mutants in terms of their sensitivity to different hygiene measures.

 
 

Pink drinks can help you run faster and further, study finds

University of Westminster, May 12, 2021

 
 
 
 

A new study led by the Centre for Nutraceuticals in the University of Westminster shows that pink drinks can help to make you run faster and further compared to clear drinks.

The researchers found that a pink drink can increase exercise performance by 4.4 per cent and can also increase a 'feel good' effect which can make exercise seem easier. 

The study, published in the journal Frontiers in Nutrition, is the first investigation to assess the effect of drink colour on exercise performance and provides the potential to open a new avenue of future research in the field of sports drinks and exercise.

During the study participants were asked to run on a treadmill for 30 minutes at a self-selected speed ensuring their rate of exertion remained consistent. Throughout the exercise they rinsed their mouths with either a pink artificially sweetened drink that was low in calories or a clear drink which was also artificially sweetened and low in calories.

Both drinks were exactly the same and only differed in appearance - the researchers added food dye to the pink drink to change the colour. 

The researchers chose pink as it is associated with perceived sweetness and therefore increases expectations of sugar and carbohydrate intake.

Previous studies have also shown that rinsing the mouth with carbohydrates can improve exercise performance by reducing the perceived intensity of the exercise, so the researchers wanted to assess whether rinsing with a pink drink that had no carbohydrate stimulus could elicit similar benefits through a potential placebo effect. 

The results show that the participants ran an average 212 metres further with the pink drink while their mean speed during the exercise test also increased by 4.4 per cent. Feelings of pleasure were also enhanced meaning participants found running more enjoyable.

Future exploratory research is necessary to find out whether the proposed placebo effect causes a similar activation to the reward areas of the brain that are commonly reported when rinsing the mouth with carbohydrates. 

Talking about the study, Dr Sanjoy Deb, corresponding author on the paper from the University of Westminster, said: "The influence of colour on athletic performance has received interest previously, from its effect on a sportsperson's kit to its impact on testosterone and muscular power. Similarly, the role of colour in gastronomy has received widespread interest, with research published on how visual cues or colour can affect subsequent flavour perception when eating and drinking. 

"The findings from our study combine the art of gastronomy with performance nutrition, as adding a pink colourant to an artificially sweetened solution not only enhanced the perception of sweetness, but also enhanced feelings of pleasure, self-selected running speed and distance covered during a run."

Vegan and omnivorous diets promote equivalent muscle mass gain, study shows

University of São Paulo (Brazil), May 19, 2021

Protein intake is more important than protein source if the goal is to gain muscle strength and mass. This is the key finding of a study that compared the effects of strength training in volunteers with a vegan or omnivorous diet, both with protein content considered adequate. 

In the study, which was conducted by researchers at the University of São Paulo (USP) in Brazil, 38 healthy young adults, half of whom were vegans and half omnivores, were monitored for 12 weeks. In addition to performing exercises to increase muscle strength and mass, the volunteers followed either a mixed diet with both animal and plant protein, or an entirely plant-based diet, both with the recommended protein content (1.6 gram of protein per kilogram of body weight per day). At the end of three months, there was no difference between vegans and omnivores in terms of muscle strength and mass increase. 

“Like any other protein in our organism, such as the proteins in our skin and hair cells, which die and are renewed, our muscles undergo synthesis and breakdown every day. Diet [protein intake] and exercise are the main protein balance regulators, favoring synthesis over breakdown,” said Hamilton Roschel, last author of the published study. Roschel is a University of São Paulo professor affiliated with both USP’s Sports and Physical Education School (EEEE) and Medical School (FM). He also heads the Applied Physiology and Nutrition Research Group jointly run by EEEE-USP and FM-USP.

Protein sources are characterized primarily on the basis of essential amino acids, especially leukin, which plays a key role in anabolic stimulation of skeletal muscles. “Animal protein has more leukin than plant protein. Leukin is an essential amino acid in the anabolic stimulus signaling process. A plant-based diet is often thought to contain less leukin and hence trigger less anabolic stimulation, potentially affecting vegans’ capacity for muscle mass gain,” Roschel said.

The study is published in Sports Medicine and resulted from the master’s research of Victoria Hevia-Larraín, with support from FAPESP

The study innovated by including a clinical analysis of the effects of protein source quality on muscle adaptation in vegans as compared with omnivores, since most research on the topic to date has focused on the acute anabolic response of muscles to protein intake under laboratory conditions and not on muscle mass as such. “Our findings show that there is no impairment of muscle mass gain for young adult vegans if they ingest the right amount of protein. In fact, the outcome of both diets was the same in this respect,” Roschel said. 

However, the researchers stress that, for the purposes of experimental control, protein intake was made the same in both diets by means of protein supplements. Omnivores and vegans were given milk serum protein isolate or soy protein respectively in accordance with individual dietary needs in order to attain the targeted protein intake. 

“In clinical practice, we know foods of animal origin generally have a higher protein content,” Roschel said. “Meat, milk and eggs contain more protein per gram than rice and beans, for example. In a clinical application with plant-based foods as the sole protein source, vegans would need to ingest a large amount of food to obtain the same amount of protein. In some specific cases, this could be a major challenge.”

The protein source (mixed or plant-based diet) made no difference, provided each subject received an adequate amount of protein. “This result corroborates other data in the literature showing that a vegan diet can absolutely be complete if it is properly planned and executed,” Roschel said. “Previous studies suggest it can even be healthier than an omnivorous diet. For this to be the case, however, it requires appropriate nutritional counseling and education regarding people’s choices in restricting their intake to plant-based sources.” 

Another point noted by Roschel is that the subjects were healthy young adults, and the results might be different for older people or subjects with health problems. “Aging entails a phenomenon known as anabolic resistance, meaning a suboptimal anabolic response to the stimuli provided by diet and exercise compared with young people. Optimal response is possible in older people only if their protein intake is higher than that of the average healthy youngster. So we should be cautious about generalizing our findings for the entire population.”

 

Yoga and breathing exercises aid children with ADHD to focus

Ural Federal University, May 17, 2021

Yoga and breathing exercises have a positive effect on children with attention deficit hyperactivity disorder (ADHD). After special classes, children improve their attention, decrease hyperactivity, they do not get tired longer, they can engage in complex activities longer. This is the conclusion reached by psychologists at Ural Federal University who studied the effect of exercise on functions associated with voluntary regulation and control in 16 children with ADHD aged six to seven years. The results of the study are published in the journal Biological Psychiatry.

"For children with ADHD, as a rule, the part of the brain that is responsible for the regulation of brain activity - the reticular formation - is deficient," said Sergey Kiselev, head of the Laboratory of Brain and Neurocognitive Development at UrFU, head of the study. "This leads to the fact that they often experience states of inadequate hyperactivity, increased distraction and exhaustion, and their functions of regulation and control suffer a second time. We used a special breathing exercise based on the development of diaphragmatic rhythmic deep breathing - belly breathing. Such breathing helps to better supply the brain with oxygen and helps the reticular formation to better cope with its role. When the reticular formation receives enough oxygen, it begins to better regulate the child's state of activity".

In addition to breathing exercises, psychologists used body-oriented techniques, in particular, exercises with polar states "tension-relaxation". The trainings took place three times a week for two to three months (depending on the program).

"Exercise has an immediate effect that appears immediately, but there is also a delayed effect. We found that exercise has a positive effect on regulation and control functions in children with ADHD and one year after the end of the exercise. This happens because the child's correct breathing is automated, it becomes a kind of assistant that allows better supply of oxygen to the brain, which, in turn, has a beneficial effect on the behavior and psyche of a child with ADHD," says Sergey Kiselev.

This technique was developed by the Russian neuropsychologist Anna Semenovich as part of a neuropsychological correction technique. UrFU psychologists tested how well this approach helps children with ADHD. But the study is pilot, says Kiselev. It showed that these exercises have a positive effect. However, more work needs to be done, involving more children with ADHD. This will also take into account factors such as gender, age, severity of the disease, concomitant problems in children (speech, regulatory, etc.).

 

 

Study findings suggest vitamin D deficiency may be associated with reduced arterial elasticity

Guizhou Medical University (China), May 17, 2021

 

According to news reporting out of Guizhou, People’s Republic of China, research stated, “There is evidence that serum 25-hydroxyvitamin D [25-(OH) D] levels may be associated with cardiovascular disease and its risk factors. This study aimed to investigate the relationship between 25-(OH) D levels and blood pressure (BP), blood lipids, and arterial elasticity in middle-aged and elderly cadres in China.In this retrospective study, we included 401 civil servants and cadres aged >42 years who underwent medical examinations at Guiyang Municipal First People’s Hospital, China in 2018.”

Our news journalists obtained a quote from the research from Guizhou Medical University, “The participants were assigned to deficiency ( 20 ng/mL), insufficiency (20-30 ng/mL), and sufficiency ( 30 ng/mL) groups according to 25-(OH) D levels in their blood. Demographics, brachial-ankle pulse wave velocity (baPWV), BP, ankle-brachial index (ABI), and blood lipids were compared among groups. The associations between 25-(OH) D and other parameters were evaluated using linear regression analysis.Median (range) 25-(OH) D levels in the deficiency (n = 162), insufficiency (n = 162), and sufficiency (n = 77) groups were 15.32 (2.93-19.88), 25.12 (20.07-29.91), and 33.91 (30.23-82.42) ng/mL, respectively. There were significant differences in systolic BP, pulse pressure, baPWV (left and right sides), ABI (left side), high-density lipoprotein-cholesterol, and triglycerides (TGs; all P< .05) among groups.”

According to the news editors, the research concluded: “Multivariate linear regression revealed that TG, left baPWV, and right baPWV were significantly negatively correlated with 25-(OH) D levels (all P< .05).In this study, 25-(OH) D levels were found to be associated with TG, left baPWV, and right baPWV values. 25-(OH) D deficiency may be associated with reduced arterial elasticity.”

 

 

Icing muscle injuries may delay recovery

Kobe University and Chiba Institute of Technology (Japan), May 19, 2021

A study using a mouse model of eccentric contraction (*1) has revealed that icing injured muscles delays muscle regeneration. The discovery was made by a research group including Associate Professor ARAKAWA Takamitsu and then PhD. Student KAWASHIMA Masato from Kobe University's Graduate School of Health Sciences, and Chiba Institute of Technology's Associate Professor KAWANISHI Noriaki et al. In addition, the researchers illuminated that this phenomenon may be related to pro-inflammatory macrophages' (*2, 3, 4) ability to infiltrate damaged cells. This research raises questions as to whether or not severe muscle injuries (such as torn muscles) should be iced.

These research results were published online as one of the Journal of Applied Physiology's Articles in Press on March 25, 2021.

Main points

  • The research results revealed that applying an ice pack to a severe muscle injury resulting from eccentric contraction may prolong the time it takes to heal.
  • The cause of this phenomenon is that icing delays the arrival of pro-inflammatory macrophages, which are responsible for the phagocytosis (*5), or removal, of damaged tissue. Furthermore, this makes difficult for the macrophages to sufficiently infiltrate the damaged muscle cells.

Research Background

Skeletal muscle injuries encompass a range of damage to muscles; from a microcellular level to a severe level. These injuries include not only those that happen during sports or schools' physical education lessons but also external injuries that occur as a result of accidents and disasters.

'RICE treatment' is a common approach for skeletal muscle injuries, regardless of the extent of the injury. This acronym stands for Rest, Ice, Compression and Elevation and is often used in physical education, sports and even medicine. Ice is commonly applied regardless of the type of muscle injury, yet little is known about the long-term effects of icing.

Ice is used to suppress inflammation, however, inflammation in response to tissue injury is one of the body's healing mechanisms. This has come to be understood as a vital response for tissue regeneration. In other words, suppressing inflammation with ice may also inhibit the body's attempt to repair itself.

Experiments investigating the effect of icing muscles after injury have produced conflicting results. Some have reported that it delays muscle regeneration while others have stated that it doesn't inhibit this process. However, none of the research up until now has investigated the effects of icing using an injury model that mimics common sports injuries caused by muscle contraction.

Using a mouse model of eccentric contraction injury, the current research team decided to observe the effects of post-injury icing. In this mouse model, injuries were induced to resemble severe torn muscles.

Research Methodology and Results

Eccentric contraction was induced by electrically stimulating the leg muscles of the mice and then exerting a stronger force during this stimulation to make the leg muscles move in the opposite direction. After this, the muscles were harvested. Icing was performed by placing polyurethane bags of ice on top of the skin over three 30 minute sessions per day, with each session being 2 hours apart. This was continued until two days after the injury. The icing was based on the usual clinically recommended method.

The researchers investigated the regenerated skeletal muscle two weeks after injury, comparing the icing group with the non-icing group. A significantly higher percentage of smaller regenerated muscle fibers were found in cross-sections from the icing group, with a greater number of medium to large fibers in the non-icing group (Figure 1). In other words, this revealed that skeletal muscle regeneration may be delayed as a result of icing.

Next, the researchers periodically took samples of muscle from the icing and non-icing groups of animals in order to investigate what was happening in the regeneration process up until this point.

In the regeneration process, inflammatory cells gather at the site of the injury, remove the debris from the damaged muscle and then begin to build new muscle. However, the results revealed that it is harder for inflammatory cells to enter the injured muscle cells if ice is applied (Figure 2).

Macrophages are typical of the inflammatory cells that enter the injured muscle. These consist of pro-inflammatory macrophages, which phagocyte damaged tissue thus causing inflammation, and anti-inflammatory macrophages (*6), which suppress the inflammatory reaction and promote repair. It is thought that pro-inflammatory macrophages change their characteristics, becoming anti-inflammatory. The results of this research team's experiments showed that icing delays the arrival of pro-inflammatory macrophages at the site of the injury (Figure 3).

These results indicate the possibility that macrophages are unable to sufficiently phagocyte the damaged muscle when ice is applied after severe muscle injuries caused by eccentric contraction, consequently delaying the formation of new muscle cells.

Comment from Associate Professor Arakawa

In sports, the mantra of immediately applying ice to an injury is commonplace, regardless of the injury's severity. However, the mechanism that we illuminated through this research suggests that not icing a severe muscle injury may lead to faster recovery. The idea of immediately cooling any type of injury is also entrenched in schools' physical education classes. I hope that in the future, the alternative option of speeding up recovery by not cooling severe muscle injuries will become known.

However, even though icing may disrupt the recovery process for severe muscle injuries, there is no denying the possibility that there are degrees of mild muscle injuries that can be iced. The next issue is to work out where to draw the line. We are now in the middle of investigating what effect icing has on slight muscle injuries.

Next, we will continue to investigate how icing should be carried out according to the extent of the muscle injury. We aim to contribute guidelines that will enable people in sports and clinical rehabilitation to make accurate judgements about whether or not to ice an injury.

 

 

Probiotics associated with fewer respiratory symptoms in overweight and older people

Findings provide further evidence of relationship between the gut and lungs

Imperial College London, May 14, 2021

Daily probiotic use was associated with fewer upper respiratory symptoms in overweight and older people, according to a study that suggests a potential role for probiotics in preventing respiratory infections. The study was selected for presentation at Digestive Disease Week® (DDW) 2021. 

"This is not necessarily the most intuitive idea, that putting bacteria into your gut might reduce your risk of respiratory infection," said Benjamin Mullish, MD, a lead researcher on the study and clinical lecturer in the Division of Digestive Diseases, Imperial College London, England, "but it's further evidence that the gut microbiome has a complex relationship with our various organ systems. It doesn't just affect how our gut works or how our liver works, it affects aspects of how our whole body works."

Researchers re-analyzed detailed daily diaries of 220 patients who participated in an earlier double-blind placebo-controlled study on probiotics and weight loss. Reviewing the entries for common symptoms of upper respiratory infection, including cough, sore throat and wheezing, researchers found that participants who took probiotics during the six-month study had a 27 percent lower overall incidence of upper respiratory tract symptoms compared to the placebo group. The effect was largest among participants who were aged 45 years or older, as well as those with obesity.

People with obesity are at higher risk for respiratory infections. Previous research has shown that probiotics reduce upper respiratory infections in healthy adults and children, but little data exists on this vulnerable population of older, overweight and people with obesity.

"These findings add to growing interest in the gut-lung axis -- how the gut and the lungs communicate with each other," Dr. Mullish said. "It's not just the gut sending out signals that affect how the lungs work. It works in both directions. It adds to the story that changes in the gut microbiome can affect large aspects of our health."

The researchers did not measure immune response, only respiratory symptoms. Future randomized clinical trials could help identify the mechanisms related to the reduction in respiratory symptoms and explore the possible impact of probiotics on the immune system, Dr. Mullish said.

 

 

Fruit discovery could provide new treatments for obesity, type 2 diabetes and cardiovascular disease

University of Warwick (UK), May 11, 2021 

 

A combination of two compounds found in red grapes and oranges could be used to improve the health of people with diabetes, and reduce cases of obesity and heart disease. The find has been made by University of Warwick researchers who now hope that their discovery will be developed to provide a treatment for patients.

 

Professor Thornalley who led research said: "This is an incredibly exciting development and could have a massive impact on our ability to treat these diseases. As well as helping to treat diabetes and heart disease it could defuse the obesity time bomb."

 

The research 'Improved glycemic control and vascular function in overweight and obese subjects by glyoxalase 1 inducer formulation' has been published in the journal Diabetes, and received funding from the UK's innovation agency, Innovate UK. The project was a collaboration between the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW) NHS Trust.

 

A team led by Paul Thornalley, Professor in Systems Biology at Warwick Medical School, studied two compounds found in fruits but not usually found together. The compounds are trans-resveratrol (tRES) - found in red grapes, and hesperetin (HESP) - found in oranges. When given jointly at pharmaceutical doses the compounds acted in tandem to decrease blood glucose, improve the action of insulin and improve thehealth of arteries.

 

The compounds act by increasing a protein called glyoxalase 1 (Glo1) in the body which neutralises a damaging sugar-derived compound called methylglyoxal (MG). MG is a major contributor to the damaging effects of sugar. Increased MG accumulation with a high energy diet intake is a driver of insulin resistance leading to type 2 diabetes, and also damages blood vessels and impairs handling of cholesterol associated with increased risk of cardiovascular diseases. Blocking MG improved health in overweight and obese people and will likely help patients with diabetes and high risk of cardiovascular disease too. It has already been proven experimentally that blocking MG improves health impairment in obesity and type 1 and type 2 diabetes.

 

Although the same compounds are found naturally in some fruits, the amounts and type required for health improvement cannot be obtained from increased fruit consumption. The compounds that increase Glo1 and are called a 'Glo1 inducer'. Pharmaceutical doses for patients with obesity, diabetes and high risk of heart disease could be given to patients in capsule form.

 

Professor Thornalley increased Glo1 expression in cell culture. He then tested the formulation in a randomised, placebo-controlled crossover clinical trial.

Thirty-two overweight and obese people within the 18-80 age range who had a BMI between 25-40 took part in the trial. They were given the supplement in capsule form once a day for eight weeks. They were asked to maintain their usual diet and their food intake was monitored via a dietary questionnaire and they were also asked not to alter their daily physical activity. Changes to their sugar levels were assessed by blood samples, artery health measured by artery wall flexibility and other assessments by analysis of blood markers.

 

The team found that the highly overweight subjects who had BMIs of over 27.5 with treatment displayed increased Glo1 activity, decreased glucose levels, improved working of insulin, improved artery function and decreased blood vessel inflammation. There was no effect of placebo.

 

Professor Thornalley said: "Obesity, type 2 diabetes and cardiovascular disease are at epidemic levels in Westernised countries. Glo1 deficiency has been identified as a driver of health problems in obesity, diabetes and cardiovascular disease."

 

"Diabetic kidney disease will be the initial target to prove effective treatment for which we are currently seeking commercial investors and partners. Our new pharmaceutical is safe and expected to be an effective add-on treatment taken with current therapy.

 

"The key steps to discovery were to focus on increasing Glo1 and then to combine tRES and HESP together in the formulation for effective treatment.

"As exciting as our breakthrough is it is important to stress that physical activity, diet, other lifestyle factors and current treatments should be adhered to."

 

Professor Martin O Weickert, Consultant in Diabetes and Endocrinology at UHCW NHS Trust, and co-applicant for the grant, said: "We were really excited to participate in this study with Warwick Medical School, as taking part in world-leading research makes a real difference to our patients both now and in the future.

"As well as the positive effects for the UHCW patients who took part in the trial, we hope this study will lead to new treatments to help patients with diabetes and cardiovascular diseases all over the world."

 

Prof. Thornalley and his team are now hoping manufacturers will want to explore the use of the compound as pharmaceutical products.

 

 

 

Vitamin D supplementation associated with less time spent in ICU among critically ill patients

Lishui People’s Hospital (China), May 18, 2021

According to news originating from Lishui, People’s Republic of China, research stated, “Vitamin D deficiency is a common scenario in critically ill patients and has been proven to be associated with poor outcomes. However, the effect of vitamin D supplementation for critically ill patients remains controversial.”

Our news correspondents obtained a quote from the research from Lishui People’s Hospital: “Thus, we conducted a meta-analysis to evaluate the effect of vitamin D supplementation among critically ill patients. Electronic databases PubMed, Embase, Scopus, and the Cochrane Library were searched for eligible randomized controlled trials between 2000 and January 2021. The primary outcome was overall mortality, and the secondary ones were the length of intensive care unit stay, the length of hospital stay, as well as the duration of mechanical ventilation. Subgroup analyses were performed to explore the treatment effect by type of admission, route of administration, dose of supplemented vitamin D, and the degree of vitamin D deficiency. A total of 14 studies involving 2,324 patients were finally included. No effect on overall mortality was found between vitamin D supplementation and control group [odds ratio (OR), 0.73; 95% CI, 0.52-1.03; I2 = 28%]. The vitamin D supplementation reduced the length of intensive care unit stay [mean difference (MD), -2.25; 95% CI, -4.07 to -0.44, I2 = 71%] and duration of mechanical ventilation (MD, -3.47; 95% CI, -6.37 to -0.57, I2 = 88%). In the subgroup analyses, the vitamin D supplementation for surgical patients (OR, 0.67; 95% CI, 0.47-0.94; I2 = 0%) or through parenteral way (OR, 0.42; 95% CI, 0.22-0.82, I2 = 0%) was associated with reduced mortality.”

According to the news reporters, the research concluded: “In critically ill patients, the supplementation of vitamin D has no effect on overall mortality compared to placebo but may decrease the length of intensive care unit stay and mechanical ventilation. Further trials are necessary to confirm our findings.”

Western diet found to impair function of immune cells in the gut

Cleveland Clinic, May 18, 2021

According to new study results, a team of researchers led by Cleveland Clinic's Thaddeus Stappenbeck, M.D., Ph.D., have found that a diet high in fat and sugar is associated with impaired intestinal immune cell function in mice. The findings, published in Cell Host & Microbe, provide novel insights into pathways linking obesity and disease-driving gut inflammation, and have implications for developing targets to treat inflammatory bowel diseases (IBD) in patients.

Using data from more than 900 patients, the researchers found that elevated body mass index is associated with abnormal Paneth cells among patients with Crohn's disease and non-IBD patients.

Paneth cells are a type of anti-inflammatory immune cell found in the intestines that helps to protect against microbial imbalances and infectious pathogens. Dysfunction of these cells is driven by a combination of genetic mutations and environmental factors. Dr. Stappenbeck and others have previously linked Paneth cell dysfunction to gut changes indicative of IBD in preclinical models and a subset of Crohn's disease patients from multiple cohorts around the world.

"With this understanding, we set out to investigate whether diet-induced obesity--specifically caused by a diet high in fat and sugar, or a 'western diet'--is one of the environmental factors that can lead to impaired Paneth cell function," said Dr. Stappenbeck, chair of Lerner Research Institute's Department of Inflammation & Immunity.

The researchers compared the effects of a western diet versus a standard diet. The team's western diet contained about 40 percent fat and an elevated level of simple carbohydrates, which better resembles the diet of an average U.S. adult than regimens prescribed in other preclinical studies.

After eight weeks, the group that ate the western diet had more abnormal Paneth cells than the group that ate a standard diet. In the western diet group, other changes become apparent two months after the Paneth cell defects, including increased gut permeability, where bacteria and toxins can enter the gut and which is well-linked with chronic inflammation. Notably, however, switching to a standard diet from the western diet completely reversed the Paneth cell dysfunction.

"When we started to look into large-scale datasets for the specific mechanisms that might connect the high-fat, high-sugar diet with the Paneth cell dysfunction, a secondary bile acid called deoxycholic acid caught our attention," said Dr. Stappenbeck. 

Deoxycholic acid is a metabolic byproduct of intestinal bacteria. Researchers found that consuming a western diet increased the bile acid in a region of the intestines called the ileum and, as a result, increased the expression of two downstream molecules, farnesoid X receptor (FXR) and type I interferon (IFN).

"For the first time, we showed how coordinated elevation of FXR and type I IFN signals in multiple cell types contribute to Paneth cell defects in response to a diet high in fat and sugar. In previous research, stimulating FXR has shown to help treat other diseases, including fatty liver disease, so we are hopeful that with additional research we can interrogate how the combination of elevated FXR and IFN signals can be targeted to help treat diet-induced gut infections and chronic inflammation."

Dr. Stappenbeck also explained that while the team was interested to learn that changing the diet regimen reversed the pathological changes, more research would be needed to determine if these changes also occur in patients.

 

 

Count your blessings: Short gratitude intervention can increase academic motivation

Ritsumeikan University (Japan), May 17, 2021
 
Because of the ongoing pandemic, lifestyles have been subjected to drastic and dynamic changes, and many work- and study-related activities are now carried out online exclusively. This, among other complex factors, has made it difficult for some people to stay focused and motivated, and psychology researchers are trying to find effective and widely applicable solutions to address such problems.

In a recent study published in BMC Psychology, researchers from Ritsumeikan University and the National Institute of Information and Communications Technology (NICT), Japan, have explored a simple strategy to increase motivation in college students by nurturing a positive emotion: gratitude. Many studies have shown that even short "gratitude interventions," which are activities that increase an individual's awareness of feelings of gratitude, can have a lasting positive effect on that person's mood, satisfaction and well-being. However, based on previous studies, the available evidence on the effect of such interventions on academic motivation is inconclusive. This prompted the researchers to test the effects of a different type of gratitude intervention: daily gratitude journaling.

"Our main hypothesis was that engaging in an online gratitude journal by writing down up to five things one felt grateful for each day could make students be more aware of their academic opportunities—their 'blessings'—and help them re-evaluate their motives and goals, ultimately improving their motivation," explains Dr. Norberto Eiji Nawa from NICT, first author of the study. They recruited 84 participants, all Japanese college students, and divided them into a control group and an intervention group. Over the course of two weeks, students in both groups had to evaluate aspects of their daily life through online questionnaires each day, but only the intervention group had to keep the online daily gratitude journal. At the start of the intervention and after one and two weeks, and one and three months, the participants had to complete the Academic Motivation Scale (AMS), a tried-and-tested tool for measuring different aspects of academic motivation.

The results were promising; through statistical analyses, the researchers found that the gratitude intervention through daily journaling significantly increased the students' academic motivation. Most notably, this robust positive effect was not restricted only to the two-week period of the intervention, as the increased level of academic motivation was maintained even after three months. In addition, through an exploratory analysis, the researchers established that the enhancement in academic motivation was mostly driven by a decrease in "amotivation scores." Amotivation, in this context, refers to the state in which a person perceives that their own actions are irrelevant to the resulting outcomes, leading to feelings of helplessness and incompetence.

Academic motivation can be one of the primary determinants of both academic achievements and satisfaction with school life, and developing widely applicable intervention strategies is critical to foster student growth. "Online interventions have the advantage of being more accessible, scalable and affordable to large portions of the population. Gathering solid evidence to support their deployment will be essential to unleash their true potential in the future," concludes Professor Noriko Yamagishi from Ritsumeikan University. It appears that the positive impact of gratitude interventions extends well beyond the already documented effects on individual well-being.

This study was partly supported by a research grant from the Ritsumeikan Inamori Philosophy Research Center. This Center aims to promote multidisciplinary research on the management philosophy advocated by Dr. Kazuo Inamori, a prominent Japanese entrepreneur and renowned philanthropist. With this major goal in mind, Professor Yamagishi, alongside Dr. Nawa, have been working on the scientific elucidation of the emotions of "altruism" and "gratitude" from the perspective of cognitive psychology and neuroscience. This particular study was conducted as part of this more overarching research. Until the day these human emotions become clearer, we can safely give this piece of advice: remember to count your blessings.

 

How Quickly Do We Become Unfit?

 

Anglia Ruskin University, May 14, 2021

Getting in shape isn’t easy. But after all that hard work, how long do we actually maintain it? Turns out that even the great effort we put into training, taking a bit of time off can mean that we become “unfit” much faster than it took us to actually get in shape.

To understand how the body becomes “unfit”, we first need to understand how we become fit. The key to becoming fitter – whether that’s improving cardiovascular fitness or muscular strength – is to exceed “habitual load”. This means doing more than our body is used to. The stress that this has on our body makes us adapt and become more tolerant, leading to higher fitness levels.

The time it takes to get fit depends on a number of factors, including fitness levels, age, how hard you work, and even environment. But some studies do indicate that even just six sessions of interval trainingcan lead to increases in maximal oxygen uptake (V02 max) – a measure of overall fitness — and improve how efficiently our body is able to fuel itself using the sugar stored in our cells during exercise.

For strength training, some gains in muscle force can be shown in as little as two weeks, but changes in muscle size won’t be seen until around 8-12 weeks.

Cardiovascular fitness

When we stop training, how quickly we lose fitness also depends on many factors – including the type of fitness we’re talking about (such as strength or cardiovascular fitness).

As an example, let’s look at a marathon runner, who is in peak athletic fitness and can run a marathon in two hours and 30 minutes. This person spends five to six days a week training, running a total of 90km. They’ve also spent the last 15 years developing this level of fitness.

Now let’s say they stopped training completely. Because the body no longer has the stresses of training forcing it to stay fit, the runner will start to lose fitness within a few weeks.

Cardiorespiratory fitness – indicated by a person’s V02 max (the amount of oxygen a person can use during exericse) – will decrease around 10% in the first four weeksafter a person stops training. This rate of decline continues, but at a slower rate over longer periods.

Intriguingly, though highly trained athletes (like our marathon runner) see a sharp decline in V02 max in the first four weeks, this decline eventually evens out, and they actually maintain a V02 higher than the average person’s. But for the average person, V02 max falls sharply, back to pre-training levels, in less than eight weeks.

 

The reason V02 max declines is due to reductions in blood and plasma volumes – which decrease by as much as 12% in the first four weeks after a person stops training. Plasma and blood volume decrease due to the lack of stress being put on our heart and muscles.

Plasma volume may even decrease by around 5% within the first 48 hours of stopping training. The effect of decreased blood and plasma volume leads to less blood being pumped around the body each heart beat. But these levels only drop to where we started – meaning we won’t get worse.

Of course, most of us aren’t marathon runners – but we’re also not immune to these effects. As soon as we stop exercising the body will start to lose these key cardiovascular adaptations at a very similar rate as highly trained athletes.

Strength training

When it comes to strength, evidence shows that in the average person, 12 weeks without training causes a significant decrease in the amount of weight we can lift. Thankfully, research shows that you maintain some of the strength you gained before you stopped training. What is intriguing is that despite the significant decrease in strength, there’s only a minimal decrease in the size of the muscle fibres.

The reason we lose muscle strength largely has to do with the fact that we’re no longer putting our muscles under stress. So when we’re no longer working our muscles hard, the muscles become “lazy”, leading the number of our muscle fibres to decrease, and fewer muscles being recruited during an activity – making us less able to lift the heavy loads we used to.

The number of muscle fibres used during exercise decreases by around 13% after just two weeks of no training – though this appears not to be accompanied by a decline in muscular force. This implies that the losses observed across the longer periods of detraining are a combination of both this initial decline in the number of muscle fibres we use, but also the slower decline in muscle mass.

For the average gym goer who lifts weights, they would experience a drop in the size of their muscles – over time finding it harder to lift heavy loads as they have less muscle fibres being recruited.

So even after all that effort to get fit, we start losing cardiovascular fitness and strength within 48 hours of stopping. But we don’t start to feel these effects for at least two to three weeks for cardiovascular fitness and around 6-10 weeks for strength. Rates of “de-training” are similar for men and women, and even for older athletes. But the fitter you are, the slower you’ll lose your gains.The Conversation

 

Non-drug therapies as good as or better than drugs for treating depression in people with dementia

St Michael’s Hospital, 

University of Toronto, University of Calgary May 17, 2021

 

Doctors should consider more "social" prescribing of non-drug approaches for depression and loneliness, say researchers

Non-drug therapies, such as exercise, appear to be as, or more, effective than drugs for reducing symptoms of depression in people with dementia, suggests research published online in The BMJ.

The findings suggest that people with dementia will derive a clinically meaningful benefit from non-drug interventions, and the researchers say doctors should consider more "social" prescribing of non-drug approaches to treat symptoms of depression and loneliness.

Fifty million people worldwide have a diagnosis of dementia. About 16% of these people also have a diagnosed major depressive disorder, and 32% will experience symptoms of depression without a formal diagnosis.

Previous trials have shown that non-drug approaches, such as exercise, alleviate symptoms of depression in people with dementia, but it's not clear how effective they are compared with drugs to reduce symptoms of depression.

To address this uncertainty, researchers analysed the results of existing trials to compare the effectiveness of drug and non-drug interventions with usual care or any other intervention targeting symptoms of depression in people with dementia.

After screening 22,138 records, they focused on and reviewed 256 studies involving 28,483 people with dementia, with or without a diagnosed major depressive disorder.

Drug approaches alone were no more effective than usual care, but they found 10 interventions associated with a greater reduction in symptoms of depression compared with usual care.

These were cognitive stimulation, exercise, reminiscence therapy (a treatment to help people with dementia remember events, people and places from their lives), cognitive stimulation with a cholinesterase inhibitor (a drug used to treat dementia), massage and touch therapy, multidisciplinary care, psychotherapy combined with reminiscence therapy and environmental modification, occupational therapy, exercise combined with social interaction and cognitive stimulation, and animal therapy.

Three interventions -- massage and touch therapy, cognitive stimulation with a cholinesterase inhibitor, and cognitive stimulation combined with exercise and social interaction -- were found to be more effective than some drugs.

The authors acknowledge some study limitations, such as being unable to explore severity of depression symptoms or effects on different types of dementia. Nor did they look at the potential costs or harms of implementing drug and non-drug interventions.

However, notable strengths included the large number of articles reviewed and use of a recognised clinical scale for capturing symptoms of depression.

As such, they say in this systematic review, "non-drug approaches were associated with a meaningful reduction in symptoms of depression in people with dementia and without a diagnosis of a major depressive disorder.

And they add that everyone -- patients, caregivers, clinicians and policy makers -- have a role in translating these findings into practice

 

 

Omega-3 lowers childhood aggression in short term, Penn research shows

University of Pennsylvania, May 13, 2021

Incorporating omega-3, vitamins and mineral supplements into the diets of children with extreme aggression can reduce this problem behavior in the short term, especially its more impulsive, emotional form, according to University of Pennsylvania researchers who published their findings in the Journal of Child Psychology and Psychiatry.

Adrian Raine, the Richard Perry University Professor of Criminology, Psychology and Psychiatry, has spent his career looking at how the brain's biological functioning affects antisocial behavior. He focuses specifically on understanding these actions and learning how to modify them, whether with something benign like a child acting out or with something extreme, in the case of a homicidal killer.

"How do you change the brain to make people better?" he asked. "How can we improve brain functioning to improve behavior?"

These questions formed the foundation for work Raine had previously done with adolescents on the African island of Mauritius. In a randomized control trial, one group received omega-3 supplements for six months, the other didn't. Those taking the fish oil saw a reduction in aggressive and antisocial behavior.

"That was my starting point," he said. "I was really excited about the results we published there."

Mauritius, however, is a tropical climate and a different culture from the United States, so Raine, a Penn Integrates Knowledge Professor, decided to test a new version of the study in Philadelphia, to aim for more broadly applicable outcomes. He partnered with Therese Richmond, the Andrea B. Laporte Professor of Nursing and associate dean for research and innovation, and several other Penn faculty, including Rose Cheney of the Perelman School of Medicine and Jill Portnoy of the Criminology Department in the School of Arts & Sciences.

The Philadelphia randomized control study placed 290 11- and 12-year-olds with a history of violence into four groups: The first received omega-3 in the form of juice, as well as multivitamins and calcium for three months. For that same duration, a second group participated in cognitive behavioral therapy, or CBT, which included meeting weekly for an hour, with time split between the child, the parent and with both together.

"Sessions focused on the links between thoughts, feelings and behaviors and also practicing alternative actions the children could take to deal with difficult situations rather than to emotionally react to something," said Richmond, who supervised the clinical trial. "It's helping the child build a toolbox of ways to interact with others. For example, if I'm angry, how might I cope with anger other than physically striking out?"All participants got homework, too.

A third group in the study took the supplements and participated in CBT, and a fourth received resources and information targeted at reducing aggressive behavior. Blood samples at the experiment's start and conclusion measured omega-3 levels in each child.

"Immediately after three months of the nutritional intervention rich in omega-3s, we found a decrease in the children's reporting of their aggressive behavior," Richmond said. The team also followed up three and six months later.

At the first check-in, participants getting the combination of CBT and omega-3s reported less aggression than the control group and the therapy-only group. By the final check-in, however, any positive effects had dissipated. What remains unknown is whether continued use of omega-3s would lead to a long-term reduction in antisocial behavior.

There were other minor limitations to the research. For one, self-reporting completed by parents and children didn't line up. The 11- and 12-year-olds in the omega-3 and CBT-supplement groups noted fewer aggressive behaviors; their parents said such tendencies hadn't changed. Also, some participants dropped out before the study had finished.

Despite these challenges, Raine, Richmond and their colleagues said the findings provide some important insight.

"No matter what program you use, could adding omega-3s to your treatment help?" Raine asked. "This suggests it could."

And though the work answers some questions, it also creates new ones, which returns to a larger point regarding the mind-action connection: It's complicated.

"We can't oversimplify the complexity of antisocial behavior. There are many causes," Raine said. "It's not just the brain. Is it a piece of the jigsaw puzzle? I think it is."

 

 

Lockdown led to positive lifestyle changes in older people

University of Stirling (Scotland), May 17, 2021

The COVID-19 lockdown was a catalyst for many older people to embrace technology, reconnect with friends and build new relationships with neighbours, according to University of Stirling research.

Understanding the coping mechanisms adopted by some over 60s during the pandemic will play a key role in developing interventions to help tackle loneliness, isolation and wellbeing in the future.

The study, led by the Faculty of Health Sciences and Sport, surveyed 1,429 participants - 84 percent (1,198) of whom were over 60 - and found many had adapted to video conferencing technology to increase online contact with existing social networks, while others reconnected with previous networks. Participants reported that lockdown had led them to engage with neighbours and other members of their communities for the first time, while several said social distancing had brought an additional meaning to life, by highlighting what was important to them.

Published in the International Journal of Environmental Research and Public Health, the paper comes six months after the study - funded under the Scottish Government Chief Scientist Office's Rapid Research in COVID-19 programme - reported in its preliminary findings that social distancing had increased feelings of loneliness in older people.

Professor of Behavioural Medicine, Anna Whittaker, who led the study, said: "Our research found that the COVID-19 lockdown triggered feelings of loneliness in older people - with many experiencing less social contact and support. However, the study also highlighted positive outcomes, for example, lockdown encouraged some older people to embrace and engage with technology - such as Zoom, Whatsapp or FaceTime - to stay in touch with loved-ones or participate in exercise classes or religious groups. Those who engaged in such activity were able to prevent high levels of loneliness, therefore, helping older adults to increase their digital literacy and use of remote social interactions could be a really important tool for addressing loneliness.

"Participants also reported actively looking for new social contact while restrictions were in place - such as contacting friends who they had not spoken to in years and increasing interactions with neighbours and other members of their communities. Significantly, many of our participants reported that social distancing has actually led them to find new sources of satisfaction in life.

"Our study also highlighted that encouraging safe social contact through physical activity and engaging with people in the community may be an effective way to reduce loneliness, improve wellbeing, increase social activity, and improve social support."

The study - which involved a survey conducted between May and July 2020 - examined the impact of social distancing during the pandemic on loneliness, wellbeing and social activity, including social support, in Scottish older adults.

Participants were asked about the strategies they adopted to increase social interaction during this time and reported that the way they interacted with their friends and family, faith, chosen group activities and, to a lesser extent, their employer and colleagues, had changed. More than 300 participants mentioned 'Zoom' - the video conferencing tool - in their answers.

More than 150 participants reported that their religious gatherings had moved online - replacing face-to-face gatherings - while 91 said that social gatherings with family and friends had changed in favour of online 'games nights'. New activities included bingo and quiz nights, while other activities moved online - such as bridge nights, book clubs, choir rehearsals, and dance and exercise classes.

The role of community - particularly neighbours - was mentioned by more than 300 participants and some reported the common experience of getting to know previously unknown neighbours and increase interaction with others in the community at local shops or parks. A pleasant Scottish summer also supported such interactions, several said.

At least 100 people said social interactions were linked to their physical activities - such as time spent outdoors while walking for exercise, walking the dogs or active commuting.

Professor Whittaker added: "Our research underlines the importance of addressing loneliness and social support in older adults - but particularly during situations where risk of isolation is high. Although specific to the pandemic, this study has wider implications of helping us to understand the impact of social distancing and social isolation on older people.

"The findings may be applicable in the future - both in and outwith pandemic situations. In Scotland, the recommendations for improvement may be through encouraging older adults to get to know their neighbours better, getting involved with local buddying systems and community initiatives, including via digital means, and engaging in physical activity, such as daily walks in the community."

Brian Sloan, Chief Executive of Age Scotland, said: "While it may prove difficult to consider any aspect of the pandemic positive as such, it is important and worthwhile to reflect on what it has taught us, both about ourselves and society and about the necessary tools to tackle Scotland's increased levels of loneliness and isolation.

"For example, we've seen first-hand how important the community response has been in terms of supporting older people throughout lockdown and it has been inspiring to witness how people across the country stepped in and stepped forward to help those in need around them. Even as restrictions ease, we hope to see this sense of community spirit continue. 

"The ongoing impact of COVID-19 has also demonstrated just how important increased digital inclusion is and how easily those without access to technology can feel out of the loop. It's reassuring to see so many older people reporting that they have been able to embrace and engage with technology to stay connected and active. 

"However, it's equally important to ensure those who are unable or do not wish to use the internet have alternative ways to stay connected to their communities and support networks.

"As we take steps towards recovery together, it is vital that no one is left behind and those most impacted are supported to play a full part in society again. 

"We know we will be living with the ongoing effects of lockdown loneliness for a long time to come, and this research will be incredibly valuable when considering how best to tackle loneliness and isolation and to improve the wellbeing of older people going forward."

 

 

Signs of Vitamin B12 Deficiency

World Health Net,  May 1, 2021

Modern nutritional research offers much more information about which nutrients are required for optimal health than in years past. The general opinion of most health care providers has been that patients should eat a balanced diet in order to make sure their nutritional needs are being met. Until the past few decades this was good advice, but the nutrients contained in most foods sold in grocery stores has been depleted, due to the way they were grown and processed. This means the nutrients most important to the proper functioning of the human body are best ingested through supplementation. Those who have a deficiency of vitamin B12 may be experiencing some serious health problems that they are not even aware of.


Food Sources of Vitamin B12
Food products that come from animals are the only sources of the vitamin, so someone who follows a vegetarian or vegan diet would most likely need to supplement B12. It is also good to supplement if one has a diet that restricts the consumption of meat, dairy, eggs because of the relatively high levels of cholesterol and fat. 

Health Problems Caused by a Vitamin B12 Deficiency
Some of these health issues are easily mistaken as symptoms of other diseases, such as diabetes. Others may be confused with common aging problems.

  • Weakness
  • Fatigue
  • Tingling and/or numbness in the extremeties
  • Memory loss and cognitive difficulties
  • Difficulty in walking, because of staggering or balance problems

Health care providers may not be able to identify these problems as a deficiency of Vitamin B12, so a blood test may be needed, in order to reach a correct diagnosis. There are a few other less common symptoms that indicate a deficiency of the vitamin.

  • Paranoia and hallucinations
  • Anemia
  • Jaundiced skin
  • An inflamed and swollen tongue

Many people are not very well educated about their nutritional needs and the problems they may experience from various deficiencies. Most people have too much stress in their lives and struggle to find enough time in the day to get everything done. People often naturally think whatever fatigue or weakness they feel is the result of not enough time and rest, but symptoms could well be due to a Vitamin B12 deficiency. 

Although seniors are most at risk for nutritional deficiencies due to dietary restrictions, a depressed appetite and medications, younger women also experience anemia due to monthly menstruation. The average person is often surprised how much better they feel once they begin a regime of Vitamin B12 supplementation. It is important to note that not all B12 supplements are the same, so if adding the vitamin to a diet it would be wise to research all the options available. One common B12 supplement actually contains arsenic and should be avoided.

Since the best source of B12 is found in foods, eating more meat, eggs, dairy and especially poultry is a good choice. Poultry is relatively low in fat and cholesterol, so it is safer for those who are at risk for heart disease.

The FDA, Shock Troops for the Pharmaceutical Industrial Complex

 

Richard Gale and Gary Null PhD

Progressive Radio Network, May 17, 2021

 

 

As of this week, over 194 million doses of the Covid-19 vaccines have been administered in the US. Consequently, a growing majority of Americans are delighted that life may return to normal because most believe they are now protected from infection. Clearly that is not the case. Bill Maher tested positive for Covid last week and had to cancel his television show for his first time since 1993. This was despite Maher having been fully vaccinated. Moreover the vaccines’ serious adverse effects are being downplayed by health officials and the media. Who will experience an adverse effect appears to be arbitrary; therefore, it is a game of Russian Roulette as to whether a person will be critically injured or be protected from the virus. One of the world’s most accomplished rock guitar musicians Eric Clapton received both doses of AstraZeneca’s Covid vaccine and had such severe reactions he feared he might never play the guitar again.  Clapton posted a message:

 

“About six weeks later [after receiving the first shot] I was offered and took the second AZ shot, but with a little more knowledge of the dangers. Needless to say the reactions were disastrous, my hands and feet were either frozen, numb or burning, and pretty much useless for two weeks, I feared I would never play again, (I suffer with peripheral neuropathy and should never have gone near the needle.) But the propaganda said the vaccine was safe for everyone.”

 

However it is not simply a miniscule few who are suffering undesirable Covid-vaccine events such as blood clots and other cardiovascular complications, anaphylaxis, severe allergic reactions, various neuropathies, abnormal menstrual bleeding and suspected miscarriages, extreme muscle weakness, fatigue, etc.  If this were the case, an argument could be made for siding with benefits over risks. Covid vaccines have only been administered for less than six months, and it is becoming increasingly clear that the risks may outweigh the benefits. Suspected numbers of miscarriages following Covid vaccines is especially worrisome. A government study published in the New England Journal of Medicine attempted to analyze and downplay the risk. Yet at the same time, the study observed a trend of 11.6% of spontaneous abortions occurring less than 13 weeks after the mRNA vaccination.  It is becoming increasingly obvious that these vaccines’ safety profiles is far less than Anthony Fauci, the FDA and the CDC are touting

 

More younger adults are experiencing adverse vaccine symptoms than from the risks due to acquiring a wild coronavirus. Worldwide reported adverse effects and deaths are escalating dramatically. In the CDC’s Vaccine Adverse Events Reporting System (VAERS), reported Covid-19 vaccine deaths have now reached 4.434 as of May 13th 2021 which is more vaccine-related deaths from conventional vaccines recorded in VAERS during the past 21 years.  Since VAERS is a passive reporting system, the actual serious adverse effect rate may be as high as 1in 10 shots. No other vaccine on the CDC’s vaccination schedule has such a poor record of safety.

 

As with Bill Maher, fully vaccinated people are still being infected and testing positive. Younger healthy adults, who earlier had an insignificant chance of becoming sick or dying from the SARS-CoV-2 virus, are now being injured and in some cases dying from the vaccines. 

 

A recent study published in JAMA observed delayed hypersensitivity vaccine reactions well after injections. The University of Pennsylvania estimates that between 5 to 10 percent of recipients of the mRNA vaccines have “severe adverse reactions” – an inordinately high percent compared to every other non-Covid vaccine. And a group of medical institutions including the University of Greifswald School of Medicine, and the Medical University of Vienna are proposing a new medical condition, “vaccine-induced prothrombotic immune thrombocytopenia,” now be associated with the AstraZeneca and Johnson and Johnson vaccines.

A recent paper warns about the dangers of vaccine-induced prion disease. The list of adverse effects continues to mount.  Pfizer document refers to the possibility of Covid vaccine shedding to the unvaccinated.  Doctors are coming forward and accusing the CDC of scrubbing the statistics of actual vaccine-related deaths. The risks were quite obvious in the vaccine makers’ own clinical trial documents before the FDA awarded Covid vaccines with emergency use approval to launch a nation-wide vaccination program. Whether or not health officials at the CDC or FDA thoroughly deliberated on the many warnings or simply ignored them is open to debate.  But the evidence strongly leans towards the latter.

 

Earlier, we presented the historical evidence of widespread corruption at the CDC; however, the FDA is far more influential because it is the final watchdog that determines a drug’s efficacy and safety profile. In the most perverse scenario, the FDA relies upon outside experts to sit on its advisory committees to review a drug’s or a vaccine’s safety. Many of these experts have a gross conflict of interests with the pharmaceutical industry.  This institutional dilemma is steeped into the FDA’s very DNA. As far back as 2006, Public Citizen discovered that 1 out of 3 of outside consultants and advisory members to the FDA had financial conflicts. The situation has only worsened over the years.

 

A Pogo investigation in October last year, uncovered several advisers on the FDA’s Vaccines and Related Biological Products Advisory Committee who had direct ties with the Covid-vaccine companies, including direct payments for consulting fees. Dr. Archana Chatterjee, for example, has received over $200,000 from agreements with these companies. The same is true for the Committee’s chairman, University of Michigan Dr. Arnold Monto who received fees from the largest vaccine firms including  Pfizer, Sanofi, GlaxoSmithKline and Novartis. The previous chair, Dr. Hana El Sahly from Baylor University, had to recuse herself due to her role in supervising Moderna’s Covid-19 vaccine clinical trials. Earlier, Monto was the principal investigator for Sanofi’s influenza vaccine. Another is the president of Meharry Medical College where coronavirus clinical trials were conducted. Three other Committee members likewise held close conflict-of-interest relationships with vaccine makers.  Shortly before issuing emergency use approval, a second Pogo analysis concluded that the FDA Committee whitewashed the warnings indicated by the Covid-19 vaccine trials. The meeting was adjourned by the FDA director for the Office of Vaccines Research and Review in favor of green-lighting the vaccines before Committee members suspicious of the clinical results could weigh-in. Prof. Carl Elliott, a medical ethicist at the University of Minnesota, summarized the problem of corporate bias now plaguing the FDA. “You do something positive for a company that you feel confident is going to pay you back for it later on,” Elliot stated. “And they do.”  The FDA‘s current rules regarding conflict of interest is strictly limited to the honor system.  In Europe, on the other hand, the European Medicines Agency strictly prohibits experts with ties to private industry from sitting on its advisory committees. 

 

Even with FDA efforts to crack down on conflicts of interests due to Congressional pressure, the industry has found other means to get their representatives onto advisory panels. And the heads of the agency willingly turn a blind eye.  A Science exposé reported on the growing strategy of “pay after” conflicts of interests. Outside advisors will declare no conflicts but then rule in favor of a drug or vaccine only to be reimbursed afterwards. The journal’s review of compensation records uncovered “pay after” schemes for the approval of 28 psychopharmacologic, arthritis, cardiac and renal drugs.” The investigation also uncovered:

 

“Of the more than $24 million in personal payments or research support from industry to the 16 top-earning advisers—who received more than $300,000 each—93% came from the makers of drugs those advisers previously reviewed or from competitors.”

 

Probing still deeper, the Pacific Legal Foundation released an analytical review of 2,952 rules issued by the Department of Health and Human Services over a 17-year period. The Foundation determined that 75 percent of these rules were unconstitutional and “issued by low-level officials and employees with no authority to issue rules.” With respect to the FDA dozens had no democratic controls and involved tens of millions of dollars ruled over by career bureaucrats.  

 

Every American who is prescribed a drug by a physician has the belief that the pill has undergone rigorous trials to scrutinize its safety and will be effective. And when there are known potential adverse effects, we blindly assume the attending physician knows these dangers. However, this is a myth perpetuated not only by drug makers but also by our own federal health agencies.

 

As we have reported on many occasions, iatrogenic deaths, deaths caused by medical error and prescribed medications is now the third leading cause of mortality in the US. The Institute of Medicine has warned about “the nation’s epidemic of medical errors.” A large percent of these errors are related to adverse drug events (ADEs). The FDA states, “ADRs are one of the leading causes of morbidity and mortality in healthcare.” Dr. Curt Furburg published an article in the Archives of Internal Medicine proposing sweeping changes throughout the FDA.  Furburg and his colleagues wrote, “We see eight major problems with the current system of assessment and assurance of drug safety at the FDA.” A fundamental problem is the FDA’s initial review for drug approval that often fails to detect serious ADRs: “A study by the US General Accountability Office (GAO) concluded that 51% of all approved drugs had at least one serious ADR that was not recognized during the approval process.”

 

A 2003 investigation published in The Independent in the UK reported “under pressure from the pharmaceutical industry, the FDA routinely conceals information it considers commercially sensitive, leaving medical specialists unable to assess the true risks [of approved drugs].” One case involved a very popular over-the-counter drug, the painkiller ibuprofen. The investigators’ search uncovered concealed data showing that ibuprofen increased heart attack risks by 25 percent. Even Freedom of Information (FOI) filings to the FDA do not produce all the information being requested. For example, a group of Swiss investigators filed an FOI to procure trial data about the musculoskeletal pain drug Celecoxib and received back only 16 of the 27 trials conducted on it. A separate FOI concerning a similar drug, Valdecoxib, had pages and paragraphs deleted because sections of the document were marked as “trade secrets.” An even worse case involving a leaked report concerning internal memos and secret FDA reports provided detailed evidence that the FDA approved 9 different antidepressants, representing a total of 22 studies enrolling 4,250 children, while knowing full well that the risk of “suicide-related events” was twice as high as children taking a placebo. These are just several examples among numerous others, which may best be summarized by a Forbes article entitled “The FDA is Basically Approving Everything.”

 

Isn't it time for real truth telling? The FDA, which was budgeted for $5.9 billion in FY 2019, is ruled and governed by a small group of political scientists who have abdicated their ethical responsibilities as physicians and medical professionals. With all the controversy and debate over the efficacy and safety of new mRNA vaccines and the aggressive emergency approval of the ineffective anti-Covid drug remdesivir, we may consider a Harvard University article published in the Journal of Law, Medicine and Ethics entitled “Institutional Corruption of Pharmaceuticals and the Myth of Safe and Effective Drugs.”  For the past four decades, the paper states, 

 

“patients have suffered from a largely hidden epidemic of side effects from drugs that usually have few offsetting benefits. The pharmaceutical industry has corrupted the practice of medicine through its influence over what drugs are developed, how they are tested, and how medical knowledge is created. Since 1906, heavy commercial influence has compromised Congressional legislation to protect the public from unsafe drugs. The authorization of user fees in 1992 has turned drug companies into the FDA’s prime clients, deepening the regulatory and cultural capture of the agency.”  

 

We are witnessing the pharmaceutical industry increasing its demands for shorter than average times for the FDA to review new drug submissions; alternatively they have an option to pay the FDA costly fees to have these drugs fast-tracked under its Accelerated Approval Program, thereby jumping over many regulatory hurdles to bring their products to market more quickly. According to a 2019 review of the Program, conducted by the University of Nebraska’s Institute for Operations Research, “from 1992 to 2008, 36% of post-market studies had not been completed, and 50% of the uncompleted studies took on average of 5 years to even begin.”  Yet throughout the duration of years, these drugs continued to be prescribed and reap enormous profits for the companies benefiting from the FDA’s loopholes. 

 

As a consequence, the FDA’s entire regulatory protocol has consistently deteriorated with each passing year. From a system originally mandated to function as a guardian to protect patients from dubious industry commercial interests, it has been transformed into an anti-preventative pipeline favoring drug companies’ bottom line and their shareholders. 

 

In 2013, the Union of Concerned Scientists released its investigative report, four years after the Obama administration launched a process to increase transparency in the federal sciences agencies --- another well-meaning Obama initiative that failed to make any fundamental change. The Union concluded that the  FDA had created a culture lacking scientific integrity, including no formal procedures for investigating scientific misconduct. 

 

The FDA’s serious failures to carry out its duties to monitor and regulate drug companies are well exemplified in the case of the North Carolina outsourcing firm Cetero.  After several years of gross negligence to thoroughly review pharmaceutical drugs, mostly generic knock-offs submitted for licensure, the agency finally uncovered Cetero’s five-year history of faking documents and data or early clinical trials and bioanalytics.  While we expect contractors who carry out clinical trials for large drug companies to be busy at work conducting research on the recorded trial data, on over 1,900 occasions there were no personnel in the Cetero facilities. Approximately 1,400 trials for roughly 100 drugs were faked. Whereas the FDA did little to conduct a thorough investigation, the European Medicines Agency on the other hand discovered that Cetero and its Big Pharm partners, including Roche and Genentech, failed to submit 80,000 reports on American approved drugs that killed over 15,000 Europeans. We need to consider that the Mayo Clinic is on record stating that the last ten years of cancer research are utterly useless due to systemic fraud, 

 

To understand the systemic rot eating away the FDA, we may take note of the research of Dr. Charles Seife and his students at New York University. Seife and his team undertook the task to investigate and analyze the extent to which the FDA covers up evidence of fraud and corruption in medical drug trials. They reviewed FDA documents for about 600 clinical trials. One of Seife’s primary questions was the frequency that FDA officials discover flagrant and intentional misconduct and subsequently decide to bury the evidence and prevent it from becoming public to the medical community.  He discovered such actions to be an official pattern within the agency. Given the high rate of content deleted or blacked out from the documents the FDA provided, the investigators could only determine which pharmaceutical company or drug was involved in 1 of 6 of the reviewed trials. For one trial alone, where FDA inspectors found significant fraud and misconduct, 78 different medical publications printed articles based upon that single study.  In an article for Slate, Seife writes, 

 

"Nobody ever finds out which data is bogus, which experiments are tainted, and which drugs might be on the market under false pretenses. The FDA has repeatedly hidden evidence of scientific fraud not just from the public, but also from its most trusted scientific advisers, even as they were deciding whether or not a new drug should be allowed on the market. Even a congressional panel investigating a case of fraud regarding a dangerous drug couldn't get forthright answers."

 

In one case, a new anti-blood clotting drug, rivaroxaban, involved four large trials recruiting thousands of patients in clinical sites in over a dozen countries. According to Seife, one of the trials "was a fiasco."  In half of the sixteen clinical sites, the FDA discovered "misconduct, fraud, fishy behavior or other practices so objectionable that the data had to be thrown out." One Colorado site falsified data. At the Mexican site, there was "systematic discarding of medical records." Despite these overwhelming problems, the drug trial was published favorably in the prestigious British journal The Lancet. The FDA found similar problems in the three other trials; in one the data was ruled "worthless." The FDA advisory committee of "expert" reviewers were only informed that inspectors discovered only "significant issues" at two sites in one of the trials. Rivaroxaban was nevertheless approved in 2011. Since then lawsuits for wrongful death from the drug continue to increase. 

 

One of the deeper flaws within the FDA’s mode of operations is that it solely relies on the studies and clinical trials conducted by drug makers without conducting any studies of its own. Consequently these private firms have complete control over the clinical data and can provide such data or not at their own discretion. For example, if a company conducts 20 clinical trials on a potential new drug and15 trials conclude it is absolutely useless or results in serious reactions and deaths, the company is only required to submit documentation for the 5 trials that are favorable. 

 

Over the years, Congressional subcommittees have voiced warnings to FDA officials to clean up their act. A House Government Reform Committee reported that both the CDC’s and FDA’s advisory committees for vaccines were thoroughly compromised with pharmaceutical conflicts of interest.  

 

One of the most glaring examples of FDA misconduct, deceit and cover-up to protect pharmaceutical interests in the agency’s history was the federal case against Merck and its anti-inflammatory drug Vioxx. Dr. David Graham, a former Associate Director for Science and Medicine in the FDA’s Office of Drug Safety, testified before the US Senate. Dr. Graham has impeccable credentials qualifying him as an expert on the failures of pharmaceutical drugs. He graduated from the Johns Hopkins University School of Medicine, and trained in Internal Medicine at Yale and in adult Neurology at the University of Pennsylvania. 

 

Dr. Graham told the Senate:

 

“During my career, I believe I have made a real difference for the cause of patient safety. My research and efforts within the FDA led to the withdrawal from the US market of Omniflox, an antibiotic that caused hemolytic anemia; Rezulin, a diabetes drug that caused acute liver failure; Fen-Phen and Redux, weight loss drugs that caused heart valve injury; and PPA (phenylpropanolamine), an over- the-counter decongestant and weight loss product that caused hemorrhagic stroke in young women.

 

“My research also led to the withdrawal from outpatient use of Trovan, an antibiotic that caused acute liver failure and death. I also contributed to the team effort that led to the withdrawal of Lotronex, a drug for irritable bowel syndrome that causes ischemic colitis; Baycol, a cholesterol-lowering drug that caused severe muscle injury, kidney failure and death; Seldane, an antihistamine that caused heart arrhythmias and death; and Propulsid, a drug for night-time heartburn that caused heart arrhythmias and death. . . .

 

“I have done extensive work concerning the issue of pregnancy exposure to Accutane, a drug that is used to treat acne but can cause birth defects in some children who are exposed in utero if their mothers take the drug during the first trimester. During my career, I have recommended the market withdrawal of twelve drugs. Only two of these remain on the market today—Accutane and Arava, a drug for the treatment of rheumatoid arthritis that I and a co-worker believe causes an unacceptably high risk of acute liver failure and death.”

 

The Los Angeles Times reported that witnesses told the Senate panel that Merck and the FDA knowingly had data well before the approval and licensure of Merck’s Vioxx painkiller that proved the drug’s serious cardiovascular health risks. Nevertheless, the FDA granted it approval without resolving the risks, and Vioxx was aggressively marketed.

 

Testifying about Merck’s Vioxx, Dr. Graham states:

 

"Today . . . you, we, are faced with what may be the single greatest drug safety catastrophe in the history of this country or the history of the world. We are talking about a catastrophe that I strongly believe could have, should have been largely or completely avoided. But it wasn’t, and over 100,000 Americans have paid dearly for this failure. In my opinion, the FDA has let the American people down, and sadly, betrayed a public trust."

 

According to Dr. Graham. “Not only did the FDA ignore known risks from Vioxx and related drugs but . . . it tried to prevent Graham and others from publicizing their own research that proved the extent of these risks.”

 

Members of Congress have echoed Graham’s concerns. Charles Grassley (R–Iowa) said he was concerned that the FDA “has a relationship with drug companies that is too cozy.”  Sen. Jeff Bingaman (D–New Mexico) said the problem was within the FDA’s own culture.“ This culture is one whereby the pharmaceutical industry, which the FDA is mandated to regulate, is the FDA’s most favored and lucrative client.

 

Sixteen years have passed since Dr. Graham’s public statements exposing the life-threatening policies and corruption that infest the FDA. It’s difficult to comprehend why the agency has been unable to clean up its act. Instead the FDA’s culture of deceit has only worsened. Nevertheless, the evidence clearly shows that our government health officials would rather support pharmaceutical profiteering than the health and safety and American citizens. In fact, 45 percent or $2.7 billion of its budget derives from private pharmaceutical “user fees.”

 

The disturbing data suggest that the FDA’s evaluation of pharmaceuticals for safety and efficacy may be so flawed that only 4% of all trial results are identified as such. As a result, FDA scientists and officials responsible for approving drugs to the market are kept largely uninformed about the egregious scientific misconduct involved in obtaining study data. Further, these erroneous and fraudulent studies are published in peer-reviewed scientific literature and accepted as valid science. The American public is ‘virtually defenseless’ if another medication proves to be unsafe after it is approved.

 

But it gets worse.  The agency has been warning against highly effective off-patent drugs to treat early SARS-CoV-2 infections such as hydroxychloroquine (HCQ) and ivermectin.  Shortly after the pandemic was formally announced, and with no promising treatment in sight, the FDA recommended HCQ but then reversed its decision in June after Anthony Fauci publicly announced the coming arrival of Gilead’s novel drug remdesivir. The FDA’s approval of remdesivir baffled many scientists, according to the journal Science, who were keeping a close watch on the drug’s clinical reports, which showed a “disproportionally high number of reports of liver and kidney problems”Nor did remdesivir lessen hospital stays or lower mortality rates.

 

Two months ago the agency issued a warning statement against the use of ivermectin. “The very next day,” reported the Alliance for Natural Health, “Merck announced positive results from a clinical trial on a new drug called molnupiravir in eliminating the virus in infected patients.”  Again, the FDA had been working in concert with the pharmaceutical industry to advance expensive experimental drugs rather than cheaper and proven drugs with decades of research to back their safety records. 

 

In addition, the FDA has waged a war against alternative medical systems for many decades, including natural supplements. Last September, the agency attempted to ban N-acetylcysteine (NAC) after it showed promise to reduce cytokine storms associated with SARS-CoV-2 infection. The supplement had already been shown to improve lung problems due to respiratory infections such as pneumonia and acute respiratory distress symptom. Three years ago, an FDA advisory committee met to consider banning five supplements made by specialized compounding pharmacies: alpha lipoic acid, CoQ10, pyridoxal-5-phosphate, creatine monohydrate  and quercetin dehydrate. Earlier the FDA had banned curcumin, boswellia and aloe vera from pharmacologic compounding. One of the key executors of the agency’s revitalized assault against supplements and the natural health industry was Trump’s appointment of Scott Gottlieb as FDA Commissioner. Following his two years at the FDA’s helm, Gottlieb quit and joined Pfizer’s Board of Directors.

 

The FDA’s argument is rather straightforward, albeit dubious; since supplements, including Vitamin C and D, Omega-3 fatty acids, and even minerals such as magnesium and zinc have not been formally submitted to the FDA for evaluation to be registered as “approved drugs,” it is against the law to make any health claims about their health benefits.  This is despite the thousands of peer-reviewed studies in the National Library of Medicine to support their efficacy. The average median cost to conduct clinical trials to meet FDA standards for approval, according to a Johns Hopkins University evaluation, is $19 million and upwards to $2-3 billion. In other words to get Vitamin D officially recommended as a viable preventative defense against Covid-19 would require a minimum of $19 million in addition to numerous fees and other legal costs prior to and after submission. And that doesn’t even address the problem of ownership since Vitamin D is a natural substance and excluded from patenting. In the meantime, supplement manufacturers are prohibited from stating the vitamin’s benefit to the public thereby contributing to a gross disservice. 

 

“Clearly these are the actions of an agency looking to restrict the supplement market,” according to the Alliance for Natural Health, “and remove as many products as possible in as many ways as possible.”  One reason is that if a vitamin or supplement were to go through the FDA licensure treadmill, the agency could potentially require a supplement’s access by prescription only. It would no longer be available over the counter. And this in turn would be another boon for the drug industry, which is already developing synthetic supplemental knock-offs that are patentable. 

 

Much of the blame lies on the shoulders of politicians on both sides of the aisle and the mainstream media who have enabled the FDA and CDC to run amok and then propagate the pharmaceutical industry’s nonsense. A recent Harvard University and Robert Wood Johnson Foundation survey reported that public trust in America’s health care system has rapidly fallen during the pandemic to 34 percent. Only 37 percent stated they had much trust in the FDA. 

 

This trend may very likely continue as a growing number of physicians and medical experts are sounding alarms over the flagrant incompetence of our federal officials leading the national efforts against Covid-19 and the approval vaccines with highly questionable safety records and expensive novel drugs that fail to warrant use. Worldwide, tens of thousands of otherwise orthodox medical professionals are charging Anthony Fauci, the CDC, FDA and the World Health Organization with gross mishandling of the pandemic.  Lawsuits are underway against national health ministries around the world for deceiving their populations with fraudulent PCR testing, fake mortality rates and unwarranted public health policies that have produced extreme harm and suffering.  As the situation deteriorates more suits will be anticipated. 

 

Sadly there is no reason to expect the FDA to undergo a structural change. For decades Congressional committees have warned the agency about it’s ignoring the public health of Americans and its revolving door policies with drug makers. Yet matters continue to worsen. A complete overhaul by adopting policies similar to the European Medicines Agency such as independent leadership divorced from the pharmaceutical complex and full public funding, would be a decent start. Another  solution could be the creation of separate and independent National Drug Safety Board without ties to private industry or overlapping conflicts of interest with the existing health agencies in dire need of reform. However that tipping point has not been reached to expect any of our politicians to switch sides and for once serve the public’s health interests

Effects of saffron extract on sleep quality: a randomized, double-blind clinical trial

 

Catholic University Louvain (Belgium). May 10. 2021

According to news reporting from Louvain la Neuve, Belgium, research stated, “A saffron extract has been found to be effective in the context of depression and anxiety, but its effect on sleep quality has not been investigating yet using objective approaches.”

The news reporters obtained a quote from the research from Catholic University Louvain (UCLouvain): “For this purpose, a randomized double-blind controlled study was conducted in subjects presenting mild to moderate sleep disorder associated with anxiety. Sixty-six subjects were randomized and supplemented with a placebo (maltodextrin) or a saffron extract (15.5 mg per day) for 6 weeks. Actigraphy was used to collect objective data related to sleep quality at baseline, at the middle and at the end of the intervention. Sleep quality was also assessed by completion of the LSEQ and PSQI questionnaires and quality of life by completion of the SF-36 questionnaire. Six weeks of saffron supplementation led to an increased time in bed assessed by actigraphy, to an improved ease of getting to sleep evaluated by the LSEQ questionnaire and to an improved sleep quality, sleep latency, sleep duration, and global scores evaluated by the PSQI questionnaire, whereas those parameters were not modified by the placebo.”

According to the news editors, the research concluded: “In conclusion, those results suggest that a saffron extract could be a natural and safe nutritional strategy to improve sleep duration and quality.”

 

 

 

 

New evidence links gut bacteria and neurodegenerative conditions

University of Florida, May 6, 2021

Neurodegenerative diseases such as Alzheimer's, Parkinson's and ALS affect millions of adults, but scientists still do not know what causes these diseases, which poses a significant roadblock to developing treatments or preventative measures.

Recent research suggests that people with these conditions exhibit changes in the bacterial composition of their digestive tract. However, given the vast diversity of microbes found in the human body, identifying which bacteria may be associated with neurodegeneration is like finding a needle in a haystack.

Seeking that proverbial needle, scientists at the University of Florida are looking in an unexpected place: the digestive tract of a tiny, translucent worm called Caenorhabditis elegans.

New research published in PLOS Pathogens establishes, for the first time, a link between specific bacteria species and physical manifestations of neurodegenerative diseases. The study's lead author is Alyssa Walker, a microbiology and cell science doctoral candidate in the UF/IFAS College of Agricultural and Life Sciences.

"Looking at the microbiome is a relatively new approach to investigating what causes neurodegenerative diseases. In this study, we were able to show that specific species of bacteria play a role in the development of these conditions," said Daniel Czyz, Walker's dissertation advisor.

Czyz is the senior author of the study and an assistant professor in the UF/IFAS department of microbiology and cell science.

"We also showed that some other bacteria produce compounds that counteract these 'bad' bacteria. Recent studies have shown that patients with Parkinson's and Alzheimer's disease are deficient in these 'good' bacteria, so our findings may help explain that connection and open up an area of future study," he added.

All neurodegenerative diseases can be traced to problems with the way proteins are handled in the body. If proteins are misfolded, they build up and accumulate in tissues. These protein aggregates, as scientists call them, interfere with cell functioning and lead to neurodegenerative disorders.

Czyz and his co-authors wanted to know if introducing certain bacteria into the C. elegans worms would be followed by protein aggregation in the worms' tissues.

"That is, in fact, what we observed. We have a way of marking the aggregates so they glow green under the microscope. We saw that worms colonized by certain bacteria species were lit up with aggregates that were toxic to tissues, while those colonized by the control bacteria were not," Czyz said. "This occurred not just in the intestinal tissues, where the bacteria are, but all over the worms' bodies, in their muscles, nerves and even reproductive organs."

Surprisingly, the offspring of affected worms also showed increased protein aggregation—even though these offspring never encountered the bacteria originally associated with the condition.

"This is very interesting because it suggests that these bacteria generate some sort of a signal that can be passed along to the next generation," Czyz said.

Worms colonized by the "bad" bacteria also lost mobility, a common symptom of neurodegenerative diseases.

"A healthy worm moves around by rolling and thrashing. When you pick up a healthy worm, it will roll off the pick, a simple device that we use to handle these tiny animals. But worms with the bad bacteria couldn't do that because of the appearance of toxic protein aggregates," explained Walker, who developed this assessment method.

"You could compare the pick to an obstacle course: just as a person with a neurodegenerative disease will have trouble getting across, the same is true with these worms, just at a much smaller scale," Czyz added.

Fun fact: Human eyebrow hairs or eyelashes make for very good picks.

"The worms are very delicate, so you need a tool that won't damage them. They are also transparent and have a simple body plan. Studies like ours are possible because these worms normally feed on bacteria," Czyz said.

"The worms are only one millimeter long, and they each have exactly 959 cells," Czyz said. "But in many ways, they are a lot like us humans—they have intestines and muscles and nerves, but instead of being composed of billions of cells, each organ is just a handful of cells. They are like living test tubes. Their small size allows us to do experiments in a much more controlled way and answer important questions we can apply in future experiments with higher organisms and, eventually, people."

Currently the Czyz lab is testing hundreds of strains of bacteria found in the human gut to see how they affect protein aggregation in C. elegans. The group is also investigating how bacteria associated with neurodegeneration cause protein misfolding at the molecular level.

Czyz is also interested in possible connections between antibiotic-resistant bacteriaand protein misfolding.

"Almost all of the bacteria we found associated with protein misfolding are also associated with antibiotic-resistant infections in people. However, it will take many more years of research before we can understand what, if any, connection there is between antibiotic resistance and neurodegenerative diseases," Czyz said.

 

Meditative practice and spiritual wellbeing may preserve cognitive function in aging

Alzheimer's Research and Prevention Foundation &Thomas Jefferson University, May 11, 2021

It is projected that up to 152 million people worldwide will be living with Alzheimer's disease (AD) by 2050. To date there are no drugs that have a substantial positive impact on either the prevention or reversal of cognitive decline. A growing body of evidence finds that targeting lifestyle and vascular risk factors have a beneficial effect on overall cognitive performance. A new review in the Journal of Alzheimer's Disease, published by IOS Press, examines research that finds spiritual fitness, a new concept in medicine that centers on psychological and spiritual wellbeing, and Kirtan Kriya, a simple 12-minute meditative practice, may reduce multiple risk factors for AD.

"The key point of this review is that making a commitment to a brain longevity lifestyle, including spiritual fitness, is a critically important way for aging Alzheimer's disease free," explain authors Dharma Singh Khalsa, MD, Alzheimer's Research and Prevention Foundation, Tucson, AZ, USA, and Andrew B. Newberg, MD, Department of Integrative Medicine and Nutritional Sciences, Department of Radiology, Marcus Institute of Integrative Health, Thomas Jefferson University, Philadelphia, PA, USA. "We hope this article will inspire scientists, clinicians, and patients to embrace this new concept of spiritual fitness and make it a part of every multidomain program for the prevention of cognitive disability."

Research reveals that religious and spiritual involvement can preserve cognitive function as we age. The authors observe that today, spirituality is often experienced outside the context of an organized religion and may be part of every religion or separate to it. Spiritual fitness is a new dimension in AD prevention, interweaving basic, psychological and spiritual wellbeing. The authors discuss the research on how these factors affect brain function and cognition. For example, psychological wellbeing may reduce inflammation, cardiovascular disease, and disability. Significantly, individuals who have a high score on a "purpose in life" (PIL) measure, a component of psychological wellbeing, were 2.4 times more likely to remain free of AD than individuals with low PIL. In another study, participants who reported higher levels of PIL exhibited better cognitive function, and further, PIL protected those with already existing pathological conditions, thus slowing their decline.

Stress and stress management are under-discussed topics in AD prevention, yet the authors point out that there is ample evidence that physical, psychological, and emotional effects of stress may elevate AD risk. Kirtan Kriya (KK) is a 12-minute singing meditation that involves four sounds, breathing, and repetitive finger movements. It has multiple documented effects on stress, such as improving sleep, decreasing depression, and increasing wellbeing. It has also been found to increase blood flow to areas of the brain involved in cognition and emotional regulation and increases gray matter volume and decreases ventricular size in long-term practitioners, which may slow brain aging. Research in healthy individuals, caregivers, and those with cognitive decline found that the practice improves cognition, slows memory loss, and improves mood.

The overall relationship between spiritual fitness and a person's complete physical and mental health is a topic of investigation in the emerging field of study called neurotheology. Early work has focused on the development of models regarding which brain areas are affected through spiritual practices such as meditation or prayer. Over the last 20 years, there has been an extensive growth in neuroimaging and other physiological studies evaluating the effect of meditation, spiritual practices, and mystical experiences. A neuroimaging study of KK found long term brain effects, during meditation and afterwards. Neurotheological studies can help understanding of how a practice such as KK can lead to more permanent effects in brain function that support spiritual fitness, according to Dr. Khalsa and Dr. Newberg.

"Mitigating the extensive negative biochemical effects of stress with meditation practices, in tandem with the creation of heightened levels of spiritual fitness, may help lower the risk of AD. Small shifts in one's daily routine can make all the difference in AD prevention," Dr. Khalsa and Dr. Newberg conclude. "We are optimistic this article will inspire future research on the topic of spiritual fitness and AD."

 

Type 2 Diabetes: Sitting can Cause Problems with Blood Sugar Levels, So Get Up and Move

Glasgow Caledonian University, May 11, 2021
 

Many people spend large portions of their day sitting, which can cause a range of health problems. But many may not realise that sitting too much can also worsen certain health conditions, such as type 2 diabetes. Research shows that spending too much time sitting can cause problems with blood sugar levels – making it even more important for those with type 2 diabetes to get plenty of physical activity into their day.

Type 2 diabetes causes the level of sugar (glucose) in the blood to become too high. For someone with diabetes, high sugar levels in the blood can cause serious damage to your body, including the heart, kidneys, eyes, feet and nerves. Controlling blood sugar levels is important for avoiding the risk of serious health problems.

Lifestyle changes, such as adjusting diet and physical activity, and diabetes medications, such as metformin or gliptin, are used to lower blood sugar levels. Yet following recommended diets and taking diabetes medications aren’t always effective at controlling blood sugar levels, as our research found. This shows us there’s a need to re-think diabetes care and management.

As type 2 diabetes can be different for everyone, how well a person controls their blood sugar levels can be influenced by different factors, such as age, gender, activity levels, diet and weight. This makes it important to target new, modifiable lifestyle factors – such as how much time is spent sitting.

Research we’ve done, which looked at 37 adults with type 2 diabetes, found that over two weeks, prolonged sitting was associated with high blood sugar levels. But we also found that when people stood up or walked around between periods of sitting, they had lower blood sugar levels. Other studies have also had similar results.

Our research has also shown that sitting less or breaking up periods of sitting with bouts of activity could be a simple way to manage blood sugar levels – including high sugar levels before and after breakfast, which is a common problem for people with type 2 diabetes. We found that simply walking more often could be beneficial to blood sugar control throughout the day.

In fact, walking every 15 minutes for as little as three minutes each time at a person’s usual pace could be enough to help them control their blood sugar – and could even be as effective as standard diabetes medications. Other research has shown that keeping bouts of sitting shorter than 15 minutes is better for blood sugar levels.

 

The reason walking – and other types of exercise – are so good for regulating blood sugar is because they make the body’s muscles work. Movement causes muscles to contract, which subsequently starts the mechanisms that allow the sugar in the blood to enter cells and fuel the body. This reduces blood sugar levels as a result.

With many people continuing to spend large portions of their days sitting while working from home, it’s important for people with type 2 diabetes to stand and walk often. Of course, that is sometimes easier said than done. But even small changes in sitting patterns throughout the day may be beneficial to a person’s blood sugar control. For example, going to the kitchen to get water or make tea can be a great opportunity to walk around for a few minutes. Even standing or walking while taking calls or during meetings can be a good idea.

It’s still important for people with type 2 diabetes to follow the advice of their doctor and stick to any special diets or take any medications they’ve been prescribed. But adding extra movement into their day will not only improve blood sugar control, it may also improve other aspects of health – including heart health and bone density.The Conversation

 

 

Grapeseed compound has senolytic activity

 

Chinese Academy of Sciences, May 10, 2021

According to news reporting based on a preprint abstract, our journalists obtained the following quote sourced from biorxiv.org:

“Aging causes functional decline of multiple organs and increases the risk of age-related pathologies.

“In advanced lives, accumulation of senescent cells, which develop the senescence-associated secretory phenotype (SASP), promotes chronic inflammation and causes diverse conditions.

“Here we report the frontline outcome of screening a natural product library with human primary stromal cells as an experimental model. Multiple candidate compounds were assayed, and grape seed extract (GSE) was selected for further investigation due to its leading capacity in targeting senescent cells.

“We found procyanidin C1 (PCC1), a polyphenolic component, plays a critical role in mediating the antiaging effects of GSE. PCC1 blocks the SASP expression when used at low concentrations. Importantly, it selectively kills senescent cells upon application at higher concentrations, mainly by enhancing production of reactive oxygen species (ROS) and disturbing mitochondrial membrane potential, processes accompanied by upregulation of Bcl-2 family pro-apoptotic factors Puma and Noxa in senescent cells. PCC1 depletes senescent cells in treatment-damaged tumor microenvironment (TME) and enhances therapeutic efficacy when combined with chemotherapy in preclinical assays. Intermittent administration of PCC1 to both senescent cell-implanted mice and naturally aged animals alleviated physical dysfunction and prolonged post-treatment survival, thus providing substantial benefits in late life stage. Together, our study identifies PCC1 as a distinct natural senolytic agent, which may be exploited to delay aging and control age-related pathologies in future medicine.”

This preprint has not been peer-reviewed.

 

 

 

 

Team Links Leaky Epithelial Barriers to 2 Billion Chronic Diseases

University of Zurich, May 7, 2021

Epithelial cells form the covering of most internal and external surfaces of the human body. This protective layer acts as a defense against invaders—including bacteria, viruses, environmental toxins, pollutants and allergens.

If the skin and mucosal barriers are damaged or leaky, foreign agents such as bacteria can enter into the tissue and cause local, often chronic inflammation with both direct and indirect consequences.

“The epithelial barrier hypothesis proposes that damages to the epithelial barrier are responsible for up to two billion chronic, non-infectious diseases,” says Cezmi Akdis, director of the Swiss Institute of Allergy and Asthma Research (SIAF), which is associated with the University of Zurich.

In the past 20 years, researchers at the SIAF alone have published more than 60 articles on how various substances damage the epithelial cells of a number of organs.

The epithelial barrier hypothesis provides an explanation as to why allergies and autoimmune diseases have been increasing for decades—they are linked to industrialization, urbanization, and westernized lifestyle.

Today many people are exposed to a wide range of toxins, such as ozone, nanoparticles, microplastics, household cleaning agents, pesticides, enzymes, emulsifiers, fine dust, exhaust fumes, cigarette smoke, and countless chemicals in the air, food, and water.

“Next to global warming and viral pandemics such as COVID-19, these harmful substances represent one of the greatest threats to humankind,” Akdis says.

Local epithelial damage to the skin and mucosal barriers lead to allergic conditions, inflammatory bowel disorders, and celiac disease. But disruptions to the epithelial barrier can also be linked to many other diseases that are characterized by changes in the microbiome.

Either the immune system erroneously attacks “good” bacteria in healthy bodies or it targets pathogenic—i.e., “bad”—invaders.

In the gut, leaky epithelial barriers and microbial imbalance contribute to the onset or development of chronic autoimmune and metabolic diseases such as diabetes, obesity, rheumatoid arthritis, multiple sclerosis, or ankylosing spondylitis.

Moreover, defective epithelial barriers have also been linked to neurodegenerative and psychiatric diseases such as Parkinson’s disease, Alzheimer’s disease, autism spectrum disorders, and chronic depression, which may be triggered or aggravated by distant inflammatory responses and changes in the gut’s microbiome.

“There is a great need to continue research into the epithelial barrier to advance our understanding of molecular mechanisms and develop new approaches for prevention, early intervention and therapy,” says Akdis.

Novel therapeutic approaches could focus on strengthening tissue-specific barriers, blocking bacteria or avoiding colonization by pathogens. Other strategies to reduce diseases may involve the microbiome, for example through targeted dietary measures. Last but not least, the focus must also be on avoiding and reducing exposure to harmful substances and developing fewer toxic products.

Study supports heart health benefits of mushroom powders

Tufts University, May 11, 2021

Adding Portobello or shiitake powder to a high-fat diet may protect arteries from the detrimental effects of a high fat diet, according to findings presented at the recent Experimental Biology event.

Scientists from Jean Mayer USDA Human Nutrition Research on Aging at Tufts University report that supplementing the diets of lab mice with the mushroom powders had lower body weight gains, compared to animals fed an unsupplemented high-fat diet.

“Despite the low body weight gains, EchoMRI analysis of body composition revealed that the overall lean mass was not affected as significantly as fat mass, indicating a plausible positive effect of mushrooms on fat metabolism and lipid profiles,” wrote the researchers in their abstract, published in the FASEB Journal .

Mushrooms

Consumer interest in mushrooms and their potential health benefits has been growing in recent years, with demand for Reishi, Chaga, Shiitake, Maitake, and the rest has never been higher and the global market was pegged at $18 billion in 2014 (up from $6 billion in 1999).

SPINS data shows surging sales of products with various types of mushrooms as primary ingredients across the natural, specialty and conventional multi-outlet retail channels. Reishi was up 91% for the 52 weeks ending September 4, 2016 versus the previous 52 weeks. Impressive growth is also being posted for Chaga (up 46%), Cordycep (up 19%) and Shiitake (up 26%),

“While several types of mushrooms have been studied for their effects on serum lipid profiles, few studies have demonstrated edible mushrooms’ effects on atherogenesis,” explained the Tufts researchers in their abstract.

Study details

L-ergothioneine facts

L-ergothioneine was first isolated as a natural compound from rye ergot (Claviceps purpurea) in 1909. It is naturally present in small amounts in food sources like mushrooms, some varieties of black and red beans (Phaseolus vulgaris) and cereals.

The human body has a dedicated transporter for the molecule, which is a potent antioxidant. 

Lab mice were divided into one of five groups: A low-fat control group (4% fat); a high fat control group (8% fat); a high-fat diet supplemented with Portobello mushroom powder; a high fat diet supplemented with shiitake mushroom powder; or a “control mixture”, which matched to the average nutrient levels of the mushroom powders.

After 16 weeks of feeding, the results showed that animals from both mushroom groups had reduced body weight gains, compared to the other dietary groups, with the weight gain lower in the shiitake group compared to the Portobello group.

Additional analyses showed that only mice fed the shiitake powder had significantly fewer aortic lesions compared to the high fat control mice and the control mixture.

“These results further support the potential role of high levels of bioactive compounds such as ergothioneine, a strong antioxidant in [shiitake mushroom], on suppression of dietary fat induced atherosclerosis, an inflammatory disease of arteries,” wrote the researchers.

The study was funded by the USDA and the Mushroom Council.

 

MIT Study Suggests Six Foot Social Distancing, Limited Occupancy Rules Are Completely Pointless

After over a year, scientists have determined that social distancing and limited occupancy rules may be totally useless

National File, April 26, 2021
 

A new study conducted by MIT scientists and released this week reveals that the six foot social distancing and limited occupancy guidelines made law in most of the civilized world have done little to slow the spread of COVID-19, and suggests the only way to reduce the spread of COVID-19 is to limit exposure to highly populated areas and areas where people are physically exerting themselves, such as gyms, or areas where people are singing or speaking, such as churches.

The study reveals that the social distancing guidelines employed throughout much of the world for over a year have done nothing to limit the spread of COVID-19, suggesting that the adaption of the guidelines did not stop the spread of the of the China-originated virus, and it can only be slowed with the employment of severe lockdowns. Paradoxically, states and cities that have engaged in severe lockdowns have seen the largest spikes of COVID-19.

“We argue there really isn’t much of a benefit to the 6-foot rule, especially when people are wearing masks,” MIT professor Martin Z. Bazant said, as reported by NBC. “It really has no physical basis because the air a person is breathing while wearing a mask tends to rise and comes down elsewhere in the room so you’re more exposed to the average background than you are to a person at a distance.” In other words, widespread mask wearing may simply change the physical vectors of transmission within a given room rather than stop it, effectively making six foot distancing rules pointless.

In their study, Bazant and the other researchers declare, “Adherence to the Six-Foot Rule would limit large-drop transmission, and adherence to our guideline, [of limiting time spent in densely populated areas], would limit long-range airborne transmission.” In the guideline, the researchers write, “To minimize risk of infection, one should avoid spending extended periods in highly populated areas. One is safer in rooms with large volume and high ventilation rates. One is at greater risk in rooms where people are exerting themselves in such a way as to increase their respiration rate and pathogen output, for example, by exercising, singing, or shouting.”

Bazant also told the media, “What our analysis continues to show is that many spaces that have been shut down in fact don’t need to be. Often times the space is large enough, the ventilation is good enough, the amount of time people spend together is such that those spaces can be safely operated even at full capacity and the scientific support for reduced capacity in those spaces is really not very good.” He added, “I think if you run the numbers, even right now for many types of spaces you’d find that there is not a need for occupancy restrictions.”

This comes on the heels of a study that suggests the Pfizer vaccine could cause severe neurodegenerative diseasescaused by brain prions created by the mRNA-style vaccine. National File reported, “‘The current RNA based SARSCoV-2 vaccines were approved in the US using an emergency order without extensive long term safety testing,’ the report declares. ‘In this paper the Pfizer COVID-19 vaccine was evaluated for the potential to induce prion-based disease in vaccine recipients.’ Prion-based diseases are, according to the CDC, a form of neurodegenerative diseases, meaning that the Pfizer vaccine is potentially likely to cause long term damage and negative health effects with regards to the brain.”

Study presents evidence supporting the use of curcumin as alternative treatment for kidney fibrosis

Zhejiang University (China), May 7, 2021

In a recent study, Chinese researchers explored the anti-fibrotic effects of curcumin, the active component of turmeric. Specifically, they looked at how curcumin affects epithelial-mesenchymal transition (EMT) and the activation of the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. EMT refers to epithelial cells undergoing molecular changes and gaining new characteristics, such as an enhanced ability to produce ECM components. Meanwhile, the PI3K/Akt pathway is one of the major cell signaling pathways that regulate fibrosis.

The researchers reported their findings in an article published in the journal Biological and Pharmaceutical Bulletin.

Curcumin is an effective alternative treatment for renal fibrosis

According to several animal studies, curcumin can protect the kidneys by preventing the development of renal fibrosis. However, the mechanisms underlying this activity are still unknown.

To explore these mechanisms and the anti-fibrotic activities of curcumin, the researchers treated human kidney tubular epithelial cells (HKCs) with transforming growth factor-B1 (TGF-B1), curcumin and a combination of both. TGF-B1 is a protein that’s involved in many cellular functions, including cell growth, proliferation, differentiation and death, as well as the induction of EMT.

The researchers used 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to assess the effect of curcumin on cell proliferation. They also used immunocytochemistry, real-time PCR and Western blot to analyze the expression of epithelial cell markers (E-cadherin and cytokeratin), mesenchymal cell markers (vimentin, alpha smooth muscle actin (a-SMA) and fibroblast-specific protein 1 (FSP1)) and key proteins involved in the Akt/mammalian target of rapamycin (mTOR) pathway.

The researchers found that low-dose curcumin (3.125 and 25?micromol/L) effectively promoted HKC proliferation. After 72 hours of incubating HKCs with TGF-B1 and curcumin, curcumin caused the cells to maintain epithelial morphology in a dose-dependent manner. It also decreased the expression of EMT-related proteins, such as vimentin, a-SMA and FSP1, and increased the expression of E-cadherin and cytokeratin. In addition, the researchers noted that curcumin reduced Akt, mTOR and P70S6K phosphorylation, which effectively suppressed the activation of the Akt/mTOR pathway in HKCs.

Based on these findings, the researchers concluded that curcumin is an effective alternative treatment for renal fibrosis because it can promote HKC proliferation and stop EMT by inhibiting the activation of the Akt/mTOR pathway activity.

 

 

Research reveals new approach to understanding our wellbeing

Swansea University, May 12, 2021

The ability to connect and feel a sense of belonging are basic human needs but new Swansea University research has examined how these are determined by more than just our personal relationships.

Research led by psychologist Professor Andrew Kemp, of the College of Human and Health Sciences, highlights the importance of taking a wider approach to wellbeing and how it can be influenced by issues such as inequality and anthropogenic climate change.

Professor Kemp worked with Ph.D. student Jess Mead and consultant clinical psychologist Dr. Zoe Fisher, of the University's Health and Wellbeing Academy, on the study which presents a transdisciplinary framework to help understand and improve wellbeing.

Professor Kemp said: "We define wellbeing as positive psychological experience, promoted by connections to self, community and environment, supported by healthy vagal function, all of which are impacted by socio-contextual factors that lie beyond the control of the individual."

The researchers say their latest findings, which have just been published in Frontiers in Psychology, are particularly topical as society looks to recover and learn from COVID-19.

He said: "Our framework has already contributed to a better understanding of how to protect wellbeing during the pandemic and has led to the development of an innovative wellbeing science intervention, targeting university students and people living with acquired brain injury."

Professor Kemp added: "We feel our invited paper is timely as it not only aligns with a post-pandemic future that requires societal transformation, but it also picks up on global efforts to promote planetary wellbeing.

"Globalization, urbanization and technological advancements have meant that humans have become increasingly disconnected from nature. This continues despite research showing that contact with nature improves wellbeing."

The research reveals the advantages to health and wellbeing derived from connecting to oneself, others and nature and emphasizes a need for focused efforts to tackle major societal issues that affect our capacity for connection.

He added: "The poorest are disproportionally impacted by major societal challenges including increasing burden of chronic disease, societal loneliness and anthropogenic climate change.

"Economic inequality has adverse impacts on the entire population, not just the poor, so improving economic inequality is fundamental to improving population wellbeing."

Taking a transdisciplinary approach to the topic of wellbeing is something currently reflected across Swansea University, particularly since the opening of the Morgan Advanced Studies Institute (MASI) which is dedicated to supporting transformative interdisciplinary research.

 

Taurine’s neuroprotective effect on cells under oxidative stress

 

University of Vale do Paraiba (Brazil), May 10, 2021

According to news reporting based on a preprint abstract, our journalists obtained the following quote sourced from biorxiv.org:

“Alzheimer’s disease (AD) is a type of dementia that affects millions of people. Although there is no cure, several study strategies seek to elucidate the mechanisms of the disease. Recent studies address the benefits of taurine. Thus, the present study aims to analyze the neuroprotective effect of taurine on human neuroblastoma, using an in vitro experimental model of oxidative stress induced by hydrocortisone in the SH-SY5Y cell line as a characteristic model of AD.

“The violet crystal assay was used for cell viability and the evaluation of cell morphology was performed by scanning electron microscopy (SEM). After pretreatment with taurine, the SH-SY5Y cell showed an improvement in cell viability in the face of oxidative stress and improved cell morphology. Thus, the treatment presented a neuroprotective effect.”

Efficacy of magnesium oxide and sodium valproate in prevention of migraine headache: a randomized, controlled, double-blind, crossover study

Mazandaran University of Medical Sciences (Iran), May 4, 2021

According to news originating from Sari, Iran, by NewsRx correspondents, research stated, “Migraine is a disabling disorder that affects the quality of life of patients. Different medications have been used in prevention of migraine headache.”

Our news journalists obtained a quote from the research from the Mazandaran University of Medical Sciences, “In this study, we evaluated the effectiveness of magnesium oxide in comparison with valproate sodium in preventing migraine headache attacks. This is a single-center, randomized, controlled, crossover trial which is double-blind, 24-week, 2-sequence, 2-period, 2-treatment. After patient randomization into two sequences, the intervention group received magnesium oxide 500 mg and the control group received valproate sodium 400 mg two tablets each day (every 12 h) for 8 weeks. The primary efficacy variable was reduction in the number of migraine attacks and number of days with moderate or severe headache and hours with headache (duration) per month in the final of 8 weeks in comparison with baseline. Seventy patients were randomized and seven dropped out, leaving 63 for analysis. In an intention-to-treat analysis, 31 patients were in group 1 (magnesium oxide-valproate) and 32 patients were in group 2 (valproate-magnesium oxide). The mean number of migraine attacks and days per month was 1.72 +/- 1.18 and 2.09 +/- 1.70, with a mean duration of 15.50 +/- 21.80 h in magnesium group and 1.27 +/- 1.27 and 2.22 +/- 1.96, with a mean duration 13.38 +/- 14.10 in valproate group.”

According to the news editors, the research concluded: “This study has shown that 500 mg magnesium oxide appears to be effective in migraine prophylaxis similar to valproate sodium without significant adverse effect.”

Vitamin D and calcium from food is associated with lower risk of early menopause

University of Massachusetts, May 10, 2021

A new study led by epidemiologists at the University of Massachusetts Amherst's School of Public Health and Health Sciences suggests that high intake of dietary vitamin D and calcium may be modestly associated with lower risk of early menopause, the cessation of ovarian function before age 45. Early menopause affects about 10 percent of women and is associated with higher risk of cardiovascular disease, osteoporosis and early cognitive decline.

Epidemiology doctoral candidate Alexandra Purdue-Smithe and her advisor Elizabeth Bertone-Johnson, with colleagues at Brigham and Women's Hospital, Boston, and Harvard Medical School, evaluated how vitamin D and calcium intake is associated with incidence of early menopause in the prospective Nurses' Health Study II. The study population includes 116,430 female U.S. registered nurses who were 25-42 years old when they responded to a baseline questionnaire.

Diet was assessed five times over the 20-year study, allowing the researchers to capture changes in food and nutrient intake over time, Purdue-Smithe notes. Participants in the study contributed more than 1 million person-years of follow-up, during which 2,041 women experienced early menopause.

The authors report the hazard ratio for early menopause comparing the highest vs. lowest dietary vitamin D intake groups was 0.83 (95% confidence interval = 0.72-0.95) and for dietary calcium 0.87 (95% CI=0.76-1.00). Details of the study, supported by the National Institutes of Health, appear in the current early online edition of the American Journal of Clinical Nutrition.

Purdue-Smithe says, "Laboratory evidence relating vitamin D to some of the hormonal mechanisms involved in ovarian aging provided the foundation for our hypothesis. However, to our knowledge, no prior epidemiologic studies have explicitly evaluated how vitamin D and calcium intake may be related to risk of early menopause. We found that after adjusting for a variety of different factors, vitamin D from food sources, such as fortified dairy and fatty fish, was associated with a 17 percent lower risk of early menopause when comparing the highest intake group to the lowest intake group."

Because higher intake of vitamin D and calcium from foods may simply act as a marker for better nutrition and overall health, Purdue-Smithe says, the researchers took into account other factors such as intake of vegetable protein and alcohol, as well as body mass index and smoking. She adds, "The large size of this study allowed us to consider a variety of potential correlates of a healthy lifestyle that might explain our findings; however, adjusting for these factors made almost no difference in our estimates."

The nutritional and reproductive epidemiologist notes that "in addition to placing women at higher risk of adverse future health outcomes, early menopause is also problematic as women are increasingly delaying childbearing into their later reproductive years. Fertility declines drastically during the 10 years leading up to menopause, so early menopause can have profound psychological and financial implications for couples who are unable to conceive as they wish. As such, it is important to identify modifiable risk factors for early menopause, such as diet."

Because associations were stronger for vitamin D and calcium from dairy sources than from non-dairy food sources in the study, and Purdue-Smithe plans further analyses investigating individual dairy foods and other components of dairy and how they may be associated with early menopause.

 

 

High levels of exercise linked to 9 years of less aging at the cellular level

Brigham Young University, May 10, 2021

\Despite their best efforts, no scientist has ever come close to stopping humans from aging. Even anti-aging creams can't stop Old Father Time.

But new research from Brigham Young University reveals you may be able to slow one type of aging--the kind that happens inside your cells. As long as you're willing to sweat.

"Just because you're 40, doesn't mean you're 40 years old biologically," Tucker said. "We all know people that seem younger than their actual age. The more physically active we are, the less biological aging takes place in our bodies."

The study, published in the medical journal Preventive Medicine, finds that people who have consistently high levels of physical activity have significantly longer telomeres than those who have sedentary lifestyles, as well as those who are moderately active.

Telomeres are the protein endcaps of our chromosomes. They're like our biological clock and they're extremely correlated with age; each time a cell replicates, we lose a tiny bit of the endcaps. Therefore, the older we get, the shorter our telomeres.

Exercise science professor Larry Tucker found adults with high physical activity levels have telomeres with a biological aging advantage of nine years over those who are sedentary, and a seven-year advantage compared to those who are moderately active. To be highly active, women had to engage in 30 minutes of jogging per day (40 minutes for men), five days a week.

"If you want to see a real difference in slowing your biological aging, it appears that a little exercise won't cut it," Tucker said. "You have to work out regularly at high levels."

Tucker analyzed data from 5,823 adults who participated in the CDC's National Health and Nutrition Examination Survey, one of the few indexes that includes telomere length values for study subjects. The index also includes data for 62 activities participants might have engaged in over a 30-day window, which Tucker analyzed to calculate levels of physical activity.

His study found the shortest telomeres came from sedentary people--they had 140 base pairs of DNA less at the end of their telomeres than highly active folks. Surprisingly, he also found there was no significant difference in telomere length between those with low or moderate physical activity and the sedentary people.

Although the exact mechanism for how exercise preserves telomeres is unknown, Tucker said it may be tied to inflammation and oxidative stress. Previous studies have shown telomere length is closely related to those two factors and it is known that exercise can suppress inflammation and oxidative stress over time.

"We know that regular physical activity helps to reduce mortality and prolong life, and now we know part of that advantage may be due to the preservation of telomeres," Tucker said.

 

 

 

How isolation affects memory and thinking skills

Harvard University, May 2021

We've all been isolated from many family members and friends during the pandemic. If you've been having a harder time remembering things or processing information since the pandemic began, it could be an isolation side effect.

"It's something I'm seeing clinically. Some people were okay before the pandemic and now they're having faster cognitive decline," says Dr. Joel Salinas, a behavioral neurologist and faculty member of the Harvard Center for Population and Development Studies.

Dr. Salinas says we don't have a lot of evidence yet to back up a clear association between pandemic lockdowns and a change in memory or thinking skills. One small 2020 study found that 60% of people with mild cognitive impairment or Alzheimer's disease experienced worsening cognition and delirium during the lockdown.

But the link between isolation and cognitive decline is more than speculation.

Isolation risks

Isolation (being cut off from social contact) was a problem for older adults long before the pandemic began. Life circumstances — such as living far from friends and family, losing a partner, or being unable to drive — often create unanticipated situations in which we find ourselves isolated. That sometimes puts health in jeopardy.

"In studies of people, isolation is associated with an increased risk for dementia, although it's unclear how high the risk is," Dr. Salinas says. "In lab animals, isolation has been shown to cause brain shrinkage and the kind of brain changes you'd see in Alzheimer's disease — reduced brain cell connections and reduced levels of brain-derived neurotrophic factor, which is important for the formation, connection, and repair of brain cells."

Isolation is also associated with elevated risks for heart attack, stroke, chronic inflammation, depression, anxiety, perceived stress, and loneliness.

People who feel lonely (disconnected from others) have been shown to have faster rates of cognitive decline than people who don't feel lonely. Loneliness is also tied to risks of losing the ability to take care of yourself and early death.

What's the link?

We don't exactly know why being isolated sometimes leads to cognitive decline. Possibilities include

  • a lack of access to crucial resources or help with daily needs
  • a decrease in stimulating mental activity that can come from social interaction
  • a reduction in social support.

"Having access to others for emotional support or listening to you seems to have a protective brain health effect — increased levels of brain-derived neurotrophic factor, and reduced risks for dementia or stroke," Dr. Salinas says.

In the pandemic, you may also be experiencing high stress levels, which can affect your brain's processing skills. "We're not good at being focused when there's danger," Dr. Salinas says. "It's the 'fight or flight' mode all the time."

If family members are noticing that you seem to be experiencing cognitive changes, Dr. Salinas says it could be a new problem — or it could be that you're spending more time together and they're picking up on changes that were already occurring before the pandemic.

Vegetarians have healthier levels of disease markers than meat-eaters

University of Glasgow (Scotland), May 10. 2021

Vegetarians appear to have a healthier biomarker profile than meat-eaters, and this applies to adults of any age and weight, and is also unaffected by smoking and alcohol consumption, according to a new study in over 166,000 UK adults, being presented at this week's European Congress on Obesity (ECO), held online this year. 

Biomarkers can have bad and good health effects, promoting or preventing cancer, cardiovascular and age-related diseases, and other chronic conditions, and have been widely used to assess the effect of diets on health. However, evidence of the metabolic benefits associated with being vegetarian is unclear. 

To understand whether dietary choice can make a difference to the levels of disease markers in blood and urine, researchers from the University of Glasgow did a cross-sectional study analysing data from 177,723 healthy participants (aged 37-73 years) in the UK Biobank study, who reported no major changes in diet over the last five years. 

Participants were categorised as either vegetarian (do not eat red meat, poultry or fish; 4,111 participants) or meat-eaters (166,516 participants) according to their self-reported diet. The researchers examined the association with 19 blood and urine biomarkers related to diabetes, cardiovascular diseases, cancer, liver, bone and joint health, and kidney function. 

Even after accounting for potentially influential factors including age, sex, education, ethnicity, obesity, smoking, and alcohol intake, the analysis found that compared to meat-eaters, vegetarians had significantly lower levels of 13 biomarkers, including: total cholesterol; low-density lipoprotein (LDL) cholesterol--the so-called 'bad cholesterol; apolipoprotein A (linked to cardiovascular disease), apolipoprotein B (linked to cardiovascular disease); gamma-glutamyl transferase (GGT) and alanine aminotransferase (AST)--liver function markers indicating inflammation or damage to cells; insulin-like growth factor (IGF-1; a hormone that encourages the growth and proliferation of cancer cells); urate; total protein; and creatinine (marker of worsening kidney function).

However, vegetarians also had lower levels of beneficial biomarkers including high-density lipoprotein 'good' (HDL) cholesterol, and vitamin D and calcium (linked to bone and joint health). In addition, they had significantly higher level of fats (triglycerides) in the blood and cystatin-C (suggesting a poorer kidney condition). 

No link was found for blood sugar levels (HbA1c), systolic blood pressure, aspartate aminotransferase (AST; a marker of damage to liver cells) or C-reactive protein (CRP; inflammatory marker). 

"Our findings offer real food for thought", says Dr Carlos Celis-Morales from the University of Glasgow, UK, who led the research. "As well as not eating red and processed meat which have been linked to heart diseases and some cancers, people who follow a vegetarian diet tend to consume more vegetables, fruits, and nuts which contain more nutrients, fibre, and other potentially beneficial compounds. These nutritional differences may help explain why vegetarians appear to have lower levels of disease biomarkers that can lead to cell damage and chronic disease."

The authors point out that although their study was large, it was observational, so no conclusions can be drawn about direct cause and effect. They also note several limitations including that they only tested biomarker samples once for each participant, and it is possible that biomarkers might fluctuate depending on factors unrelated to diet, such as existing diseases and unmeasured lifestyle factors. They also note that were reliant on participants to report their dietary intake using food frequency questionnaires, which is not always reliable.

 

 

Alzheimer's study: A Mediterranean diet might protect against memory loss and dementia

German Center for Neurodegenerative Diseases, May 6, 2021

In Alzheimer's disease, neurons in the brain die. Largely responsible for the death of neurons are certain protein deposits in the brains of affected individuals: So-called beta-amyloid proteins, which form clumps (plaques) between neurons, and tau proteins, which stick together the inside of neurons. The causes of these deposits are as yet unclear. In addition, a rapidly progressive atrophy, i.e. a shrinking of the brain volume, can be observed in affected persons. Alzheimer's symptoms such as memory loss, disorientation, agitation and challenging behavior are the consequences.

Scientists at the DZNE led by Prof. Michael Wagner, head of a research group at the DZNE and senior psychologist at the memory clinic of the University Hospital Bonn, have now found in a study that a regular Mediterranean-like dietary pattern with relatively more intake of vegetables, legumes, fruit, cereals, fish and monounsaturated fatty acids, such as from olive oil, may protect against protein deposits in the brain and brain atrophy. This diet has a low intake of dairy products, red meat and saturated fatty acids.

A nationwide study

A total of 512 subjects with an average age of around seventy years took part in the study. 169 of them were cognitively healthy, while 343 were identified as having a higher risk of developing Alzheimer's disease - due to subjective memory impairment, mild cognitive impairment that is the precursor to dementia, or first-degree relationship with patients diagnosed with Alzheimer's disease. The nutrition study was funded by the Diet-Body-Brain competence cluster of the German Federal Ministry of Education and Research (BMBF) and took place as part of the so-called DELCODE study of the DZNE, which does nationwide research on the early phase of Alzheimer's disease - that period before pronounced symptoms appear.

"People in the second half of life have constant eating habits. We analyzed whether the study participants regularly eat a Mediterranean diet - and whether this might have an impact on brain health ", said Prof. Michael Wagner. The participants first filled out a questionnaire in which they indicated which portions of 148 different foods they had eaten in the past months. Those who frequently ate healthy foods typical of the Mediterranean diet, such as fish, vegetables and fruit, and only occasionally consumed foods such as red meat, scored highly on a scale.

An extensive test series

The scientists then investigated brain atrophy: they performed brain scans with magnetic resonance imaging (MRI) scanners to determine brain volume. In addition, all subjects underwent various neuropsychological tests in which cognitive abilities such as memory functions were examined. The research team also looked at biomarker levels (measured values) for amyloid beta proteins and tau proteins in the so-called cerebrospinal fluid (CSF) of 226 subjects.

The researchers, led by Michael Wagner, found that those who ate an unhealthy diet had more pathological levels of these biomarkers in the cerebrospinal fluid than those who regularly ate a Mediterranean-like diet. In the memory tests, the participants who did not adhere to the Mediterranean diet also performed worse than those who regularly ate fish and vegetables. "There was also a significant positive correlation between a closer adherence to a Mediterranean-like diet and a higher volume of the hippocampus. The hippocampus is an area of the brain that is considered the control center of memory. It shrinks early and severely in Alzheimer's disease," explained Tommaso Ballarini, PhD, postdoctoral fellow in Michael Wagner's research group and lead author of the study.

Continuation of nutrition study is planned

"It is possible that the Mediterranean diet protects the brain from protein deposits and brain atrophy that can cause memory loss and dementia. Our study hints at this," Ballarini said. "But the biological mechanism underlying this will have to be clarified in future studies." As a next step, Ballarini and Wagner now plan to re-examine the same study participants in four to five years to explore how their nutrition - Mediterranean-like or unhealthy - affects brain aging over time.

 

 

 

Social isolation has a profound and increasingly negative impact on physical functioning in older adults

 
 
 
 

University of Southern Denmark, May 11, 2021

Social isolation among older adults is associated with poor health and premature mortality, but the connection between social isolation and physical functioning is poorly understood. New research generates more robust evidence about the associations between social isolation and physical functioning and how this accelerates over time, reports the American Journal of Preventive Medicine, published by Elsevier. It also highlights the importance of incorporating strategies to reduce social isolation and promote successful aging.

"Physical functioning is understood to influence the health of individuals. And social isolation is prevalent among older adults," explained lead investigator Borja del Pozo Cruz, PhD, Centre for Active and Healthy Ageing, Department of Sports Science and Clinical Biomechanics, University of Southern Denmark, Odense, Denmark. "However, the true extent of the relationship between social isolation and physical functioning was not fully understood. We needed to shed some more light on this relationship, as it plays an important role in individual aging."

As individuals age, physical functioning declines, which can result in a loss of functional independence, onset of disability, and increased mortality, with significant personal, community, and economic costs. Older adults who are socially integrated may be more likely to engage in physical activity, which would in turn elicit improvements in their physical functioning.

Social isolation is a significant problem facing the health and well-being of individuals across the life course. Individuals who are socially isolated are more likely to experience mental health problems, develop dementia, and have increased risk of premature mortality. Social isolation is particularly worrisome among older adults, with data from the United States indicating that one in four older adults is isolated or severely isolated. Given the worldwide trends in population aging, social isolation among older adults is likely to become an increasing burden in years to come.

To examine the longitudinal associations between social isolation and physical functioning, investigators used nine waves of panel data from 2011 to 2019 from the National Health and Aging Trends Study (NHATS), a large US-representative sample of adults 65 or older. This means that the results can be generalized to the US population of older adults. The study analyzed observations from 12,427 NHATS participants to measure how individual changes in social isolation were associated with individual changes in objectively assessed physical functioning. Social isolation was captured through the Social Isolation Index (SII). Physical functioning was assessed using the NHATS version of the Short Physical Performance Battery (SPPB). The analytic sample encompassed 54,860 observations, meaning that respondents were observed 4.41 times on average.

These findings add to a growing evidence base demonstrating the negative consequences of social isolation, specifically the acceleration of aging decline trajectories in physical functioning. Investigators were able to identify with a high degree of granularity how the association between social isolation and physical functioning shifts over old age and exacerbates the decline in physical functioning associated with aging. The results showed that the older individuals are, the greater the extent to which social isolation impacts their health.

A small but growing number of observational studies in the UK, Japan, and China have identified negative associations between social isolation and physical functioning in samples of older adults. The current study resonates with and complements those results. However, the robust data generated by this national rather than community-based study enable findings to be generalized to a national population.

"Physical functioning is a well-established marker of general health and it has been previously correlated with morbidity and mortality," noted Dr. del Pozo Cruz. "We demonstrate in this study that social isolation has a profound impact on the physical functioning in older adults. Mandated social contact restrictions and lockdowns due to COVID-19, coupled with more severe consequences of contagion among older adults, have likely exacerbated this trend.

Study findings suggest that public health interventions should turn their attention to the social environments in which older people are embedded, in particular for those at risk of isolation.

"Social isolation is one of the biggest challenges that societies face in the 21st century. We have to start thinking about this issue now to avoid more serious consequences down the track," added Dr. del Pozo Cruz.

 

 

 

How bullying and obesity can affect girls' and boys' mental health

Uppsala University (Sweden), May 7, 2021

Depressive symptoms are more common in teenage girls than in their male peers. However, boys' mental health appears to be affected more if they suffer from obesity. Irrespective of gender, bullying is a considerably greater risk factor than being overweight for developing depressive symptoms. These conclusions are drawn by researchers at Uppsala University who monitored adolescents for six years in a questionnaire study, now published in the Journal of Public Health.

"The purpose of our study was to investigate the connection between body mass index (BMI) and depressive symptoms, and to take a close look at whether being subjected to bullying affects this relationship over time. We also wanted to investigate whether any gender differences existed," says Sofia Kanders, a Ph.D. student at Uppsala University's Department of Neuroscience.

In the study, young people born in Västmanland County, replied to questions about their height, weight and depressive symptoms on three separate occasions (2012, 2015 and 2018). The respondents' mean age was 14.4 years on the first occasion and 19.9 years on the last.

Based on BMI, the adolescents were divided into three groups: Those with normal weight, those who were overweight and those with obesity respectively. They were also grouped according to the extent of their depressive symptoms.

Overall, regardless of their weight, the girls stated more frequently that they had depressive symptoms. In 2012, 17 percent of the girls and 6 percent of the boys did so. By 2015, the proportions of adolescents with these symptoms had risen to 32 percent for the girls and 13 percent for the boys. The corresponding figures for 2018 were 34 and 19 percent respectively.

A higher BMI did not, as far as the researchers could see, affect the girls' mental well-being to any great extent. Among the boys, however, the pattern observed was entirely different.

"When we analyzed girls and boys separately, we saw that for boys with obesity in 2012, the risk for having depressive symptoms in 2015 was, statistically, five times higher than for normal-weight boys. In the girls we found no such connection," Kanders says.

The study has been unable to answer the question of what causes this gender difference, and the researchers think more research is needed in this area.

The young respondents were also asked about bullying—for example, to state whether, in the past year, they had been physically exposed to blows and kicks, teased or excluded, subjected to cyberbullying (abusive texting or other electronic or web bullying), or bullied by an adult at school.

In every analysis, exposure to bullying was associated with a higher risk of depressive symptoms. This connection was also evident six years later, especially in overweight boys. The researchers believe that these results seem to indicate a gender difference in how BMI and bullying together drive development of future depressive symptoms.

"One key conclusion and take-home message from our study is that bullying can affect mental illness for a long time to come, which therefore makes preventive measures against bullying in schools extremely important," Kanders says.

 

 

Efficacy of magnesium oxide and sodium valproate in prevention of migraine headache: a randomized, controlled, double-blind, crossover study

Mazandaran University of Medical Sciences (Iran), May 4, 2021

According to news originating from Sari, Iran, by NewsRx correspondents, research stated, “Migraine is a disabling disorder that affects the quality of life of patients. Different medications have been used in prevention of migraine headache.”

Our news journalists obtained a quote from the research from the Mazandaran University of Medical Sciences, “In this study, we evaluated the effectiveness of magnesium oxide in comparison with valproate sodium in preventing migraine headache attacks. This is a single-center, randomized, controlled, crossover trial which is double-blind, 24-week, 2-sequence, 2-period, 2-treatment. After patient randomization into two sequences, the intervention group received magnesium oxide 500 mg and the control group received valproate sodium 400 mg two tablets each day (every 12 h) for 8 weeks. The primary efficacy variable was reduction in the number of migraine attacks and number of days with moderate or severe headache and hours with headache (duration) per month in the final of 8 weeks in comparison with baseline. Seventy patients were randomized and seven dropped out, leaving 63 for analysis. In an intention-to-treat analysis, 31 patients were in group 1 (magnesium oxide-valproate) and 32 patients were in group 2 (valproate-magnesium oxide). The mean number of migraine attacks and days per month was 1.72 +/- 1.18 and 2.09 +/- 1.70, with a mean duration of 15.50 +/- 21.80 h in magnesium group and 1.27 +/- 1.27 and 2.22 +/- 1.96, with a mean duration 13.38 +/- 14.10 in valproate group.”

According to the news editors, the research concluded: “This study has shown that 500 mg magnesium oxide appears to be effective in migraine prophylaxis similar to valproate sodium without significant adverse effect.”

Vitamin D and calcium from food is associated with lower risk of early menopause

University of Massachusetts, May 10, 2021

A new study led by epidemiologists at the University of Massachusetts Amherst's School of Public Health and Health Sciences suggests that high intake of dietary vitamin D and calcium may be modestly associated with lower risk of early menopause, the cessation of ovarian function before age 45. Early menopause affects about 10 percent of women and is associated with higher risk of cardiovascular disease, osteoporosis and early cognitive decline.

Epidemiology doctoral candidate Alexandra Purdue-Smithe and her advisor Elizabeth Bertone-Johnson, with colleagues at Brigham and Women's Hospital, Boston, and Harvard Medical School, evaluated how vitamin D and calcium intake is associated with incidence of early menopause in the prospective Nurses' Health Study II. The study population includes 116,430 female U.S. registered nurses who were 25-42 years old when they responded to a baseline questionnaire.

Diet was assessed five times over the 20-year study, allowing the researchers to capture changes in food and nutrient intake over time, Purdue-Smithe notes. Participants in the study contributed more than 1 million person-years of follow-up, during which 2,041 women experienced early menopause.

The authors report the hazard ratio for early menopause comparing the highest vs. lowest dietary vitamin D intake groups was 0.83 (95% confidence interval = 0.72-0.95) and for dietary calcium 0.87 (95% CI=0.76-1.00). Details of the study, supported by the National Institutes of Health, appear in the current early online edition of the American Journal of Clinical Nutrition.

Purdue-Smithe says, "Laboratory evidence relating vitamin D to some of the hormonal mechanisms involved in ovarian aging provided the foundation for our hypothesis. However, to our knowledge, no prior epidemiologic studies have explicitly evaluated how vitamin D and calcium intake may be related to risk of early menopause. We found that after adjusting for a variety of different factors, vitamin D from food sources, such as fortified dairy and fatty fish, was associated with a 17 percent lower risk of early menopause when comparing the highest intake group to the lowest intake group."

Because higher intake of vitamin D and calcium from foods may simply act as a marker for better nutrition and overall health, Purdue-Smithe says, the researchers took into account other factors such as intake of vegetable protein and alcohol, as well as body mass index and smoking. She adds, "The large size of this study allowed us to consider a variety of potential correlates of a healthy lifestyle that might explain our findings; however, adjusting for these factors made almost no difference in our estimates."

The nutritional and reproductive epidemiologist notes that "in addition to placing women at higher risk of adverse future health outcomes, early menopause is also problematic as women are increasingly delaying childbearing into their later reproductive years. Fertility declines drastically during the 10 years leading up to menopause, so early menopause can have profound psychological and financial implications for couples who are unable to conceive as they wish. As such, it is important to identify modifiable risk factors for early menopause, such as diet."

Because associations were stronger for vitamin D and calcium from dairy sources than from non-dairy food sources in the study, and Purdue-Smithe plans further analyses investigating individual dairy foods and other components of dairy and how they may be associated with early menopause.

 

 

High levels of exercise linked to 9 years of less aging at the cellular level

Brigham Young University, May 10, 2021

\Despite their best efforts, no scientist has ever come close to stopping humans from aging. Even anti-aging creams can't stop Old Father Time.

But new research from Brigham Young University reveals you may be able to slow one type of aging--the kind that happens inside your cells. As long as you're willing to sweat.

"Just because you're 40, doesn't mean you're 40 years old biologically," Tucker said. "We all know people that seem younger than their actual age. The more physically active we are, the less biological aging takes place in our bodies."

The study, published in the medical journal Preventive Medicine, finds that people who have consistently high levels of physical activity have significantly longer telomeres than those who have sedentary lifestyles, as well as those who are moderately active.

Telomeres are the protein endcaps of our chromosomes. They're like our biological clock and they're extremely correlated with age; each time a cell replicates, we lose a tiny bit of the endcaps. Therefore, the older we get, the shorter our telomeres.

Exercise science professor Larry Tucker found adults with high physical activity levels have telomeres with a biological aging advantage of nine years over those who are sedentary, and a seven-year advantage compared to those who are moderately active. To be highly active, women had to engage in 30 minutes of jogging per day (40 minutes for men), five days a week.

"If you want to see a real difference in slowing your biological aging, it appears that a little exercise won't cut it," Tucker said. "You have to work out regularly at high levels."

Tucker analyzed data from 5,823 adults who participated in the CDC's National Health and Nutrition Examination Survey, one of the few indexes that includes telomere length values for study subjects. The index also includes data for 62 activities participants might have engaged in over a 30-day window, which Tucker analyzed to calculate levels of physical activity.

His study found the shortest telomeres came from sedentary people--they had 140 base pairs of DNA less at the end of their telomeres than highly active folks. Surprisingly, he also found there was no significant difference in telomere length between those with low or moderate physical activity and the sedentary people.

Although the exact mechanism for how exercise preserves telomeres is unknown, Tucker said it may be tied to inflammation and oxidative stress. Previous studies have shown telomere length is closely related to those two factors and it is known that exercise can suppress inflammation and oxidative stress over time.

"We know that regular physical activity helps to reduce mortality and prolong life, and now we know part of that advantage may be due to the preservation of telomeres," Tucker said.

Why are Hydroxychloroquine and Ivermectin Being Officially Suppressed

 Richard Gale and Gary Null PhD

Had the FDA and Anthony Fauci’s National Institute for Allergies and Infectious Disease (NIAID) started approving existing clinically-proven and inexpensive drugs for treating malaria, parasites and other pathogens at the start of the pandemic, millions of people would have been saved from experiencing serious infections or dying from the SARS-CoV-2 virus. Why federal health officials never followed this strategy is a question the mainstream media refuses to ask.

Why are Hydroxychloroquine and Ivermectin Being Officially Suppressed

 

Richard Gale and Gary Null PhD

Progressive Radio Network, May 10, 2021

 

 

Had the FDA and Anthony Fauci’s National Institute for Allergies and Infectious Disease (NIAID) started approving existing clinically-proven and inexpensive drugs for treating malaria, parasites and other pathogens at the start of the pandemic, millions of people would have been saved from experiencing serious infections or dying from the SARS-CoV-2 virus. Why federal health officials never followed this strategy is a question the mainstream media refuses to ask. 

 

Another question that the medical establishment, let alone our compliant media, is why have they failed to ask whether there are reliable studies in the peer-reviewed literature and testimonies from thousands of day-to-day clinical physicians worldwide who treat Covid-19 patients with these drugs, in particular hydroxychloroquine (HCQ) and Ivermectin. In most nations, there has been enormous success in treating Covid patients at the early and moderate stages of infection. However, in the US, Anthony Fauci, Bill Gates, the FDA and our institutional medical leaders have categorically denied their use.  In fact they are quick to erect obstacles to prevent them from being prescribed.

 

When these questions are posited as a general argument for advocating expedient measures to protect public health during this pandemic, would it not have been wise to have prioritized HCQ, Ivermectin, and other remedies with a record of curtailing Covid, such as the antibiotic azirthromicin, zinc, selenium, Vitamins C and D, and melatonin as a first line of defense?  There was absolutely no need to have waited for experimental vaccines or experimental drugs such as Remdesivir before the pandemic became uncontrollable.  But this is what Fauci and Trump permitted to happen.

 

If this strategy of medical intervention had been followed, would it have been successful?  The answer is likely an unequivocal “yes”.  Both HCQ and, even better, Ivermectin have been prophylactically prescribed by physicians working on pandemic’s front lines with enormous success.  Yet those American physicians struggling to get this urgent message out to federal health officials are being marginalized and ridiculed en masse. Only in the US, the UK, France, South Africa and several other developed nations has there been a stubborn hubris to deny their effectiveness, and where there have been concerted efforts to undermine these cheaper alternative remedies. The World Health Organization recommends Ivermectin for Covid-19 so why not the US and these other nations? Under oath, multiple physicians and professors at American medical schools have testified before Congress to present the scientific evidence supporting HCQ and Ivermectin.  These are otherwise medical professionals at the very heart of treating Covid-19 patients. 

 

Today, American journalism is in shambles. In fact, it is a disgrace.  The American public is losing its trust the media. Whether it is CNN, the New York Times, the Washington Post, NPR or PBS, they each have unlimited resources to properly investigate the federal and institutional machinery behind the government health policies being thrust upon us.  Yet no mainstream journalist has found the moral compass to bring this truth to the public. 

 

In the meantime, we are allowing millions to die, and countless others to be seriously affected from a severe infection because of professional medical neglect and a healthcare system favoring the pharmaceutical industry’s frantic rush to develop expensive novel drugs and experimental vaccines. The incentive by the drug makers is to take every advantage available within the FDA’s emergency use loopholes to get their products approved as quickly as possible.  The primary advantage is that these novel drugs and vaccines can then leap over regulatory hurdles, which otherwise would require them to conduct lengthy and thorough clinical trials to prove their efficacy and safety. The consequence is that none of the new pharmaceutical Covid-19 interventions have been adequately reviewed.

 

On the other hand, HCQ and Ivermectin have an established legacy of prior research and have been on the market for decades. Worldwide, it is not unreasonable to claim that billions of people have been treated with these drugs.  

 

Below is a breakdown of the studies conducted so far for HCQ, Ivermectin and Vitamin D specifically for combatting the SARS-CoV-2 virus

 

Hydroxychloroquine

 

291 studies, 218 peer-reviewed have been conducted specifically for Covid-19

241 have been clinical trials that involved 3,875 scientists and over 366,000 patients

33 were randomize controlled trials

65% improvement in 26 early treatment trials

72% improvement in 11 early stage infection treatment mortality results

22% improvement in 164 late stage infection treatment trials (patients in serious condition)

Ivermectin 

 

92 studies, 52 peer-reviewed have been conducted specifically for Covid-19

54 have been clinical trials that involved 442 scientists and over 17,600 patients

27 were randomized controlled trials 

85% improvement in 14 prophylaxis trials

80% improvement in 20 early stage infection treatment trials

47% improvement in 20 late stage infection treatment trials

74% improvement in 20 mortality results

Vitamin D

 

74 studies conducted by over 650 scientists

52 sufficiency studies with 12,000 patients

23 treatment trials with 23,000 patients

53% improvement in 23 treatment trials

53% improvement in 52 sufficiency studies

63% improvement in 14 treatment mortality results

Full list of Vitamin D studies and details:  https://c19vitamind.com

 

Please share this information. The inept policies and measures being taken by our federal health officials and by both the former Trump and present Biden administrations are unparalleled in American healthcare history. And never before has the media been so willing to self-censor and been so grossly irresponsible to hide the published science and the truth.

Higher omega-3 levels linked with lower risk of death during 16-year period

The Fatty Acids and Outcomes Research Consortium, April 28 2021. 

 

An analysis of prospective studies published on April 22, 2021 in Nature Communications uncovered a decreased risk of mortality during an average of 16 years among men and women who had higher red blood cell or plasma levels of omega-3 fatty acids. 

The analysis was conducted by William S. Harris and The Fatty Acids and Outcomes Research Consortium (FORCE). Dr Harris is a codeveloper of the Omega-3 Index, which measures omega 3 levels in red blood cell membranes. The team examined 17 prospective studies that evaluated associations between the risk of death from all causes and levels of the omega-3 fatty acids alpha linolenic acid (ALA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), and EPA plus DHA. 

During the studies’ follow-up periods, 15,720 deaths occurred among a total of 42,466 men and women. Subjects whose EPA, DPA, DHA, and EPA plus DHA levels were among the top 10% of participants experienced a 9% to 13% reduction in mortality from all causes during follow-up compared to men and women whose levels were among the lowest 10%. When cause-specific mortality was examined, having EPA, DPA, DHA, or EPA plus DHA levels among the highest 10% was associated with a lower risk of cardiovascular mortality, cancer mortality and mortality from all other causes combined (with the exception of the association between DHA and reduced cancer mortality, which was not considered significant). 

"Since all of these analyses were statistically adjusted for multiple personal and medical factors (i.e., age, sex, weight, smoking, diabetes, blood pressure, etc., plus blood omega-6 fatty acid levels), we believe that these are the strongest data published to date supporting the view that over the long-term, having higher blood omega-3 levels can help maintain better overall health," Dr Harris concluded.

 

 

New study shows tree nuts may play a role in both weight loss and weight maintenance

 

University of California at Los Angeles, May 4, 2021 

In a randomized, controlled study* published online in the journal, Nutrients, researchers found that including mixed tree nuts in a weight management program resulted in significant weight loss and improved satiety.

Researchers at UCLA compared 95 overweight/obese men and women (BMI 27.0-35.0 kg/m2) ages 30-68 years who consumed either 1.5 ounces of mixed tree nuts or a pretzel snack. Both snacks provided the same number of calories, as part of a hypocaloric weight loss diet (500 calories less than resting metabolic rate) over 12 weeks. This was followed by an isocaloric weight maintenance program for an additional 12 weeks. 

Participants experienced significant weight loss (12 weeks: -1.6 kg and -1.9 kg and 24 weeks: -1.5 kg and -1.4 kg) in the tree nut and pretzel snack groups, respectively. Both groups also showed a significant decrease in BMI at 12 weeks, compared to baseline. However, satiety was significantly higher at the end of week 24 in the mixed tree nut group, and there was a trend toward greater weight maintenance compared to the pretzel group. Moreover, the dropout rate was significantly lower in the mixed tree nut group (16.4%) compared to the pretzel (35.9%) group. And, heart rate was decreased significantly, compared to baseline, in those consuming tree nuts, but not pretzels. 

"Tree nuts (almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts) are a great source of protein, healthy fats and fiber," explained lead researcher, Zhaoping Li, MD, PhD, Professor of Medicine and Chief of the Division of Clinical Nutrition at UCLA. "This makes them so satiating and may be a major reason why we saw less weight gain in the tree nut group during weight maintenance, and a significantly lower dropout rate compared to the pretzel group." 

Recent research has shown that more than 40 percent of Americans are overweight or obese.** During the past year many Americans have gained weight while sheltering in place, partly due to less exercise and more snacking. One study estimates a weight gain of 1.5 pounds per month.*** "We know most people get about 25% of their calories each day from snacks and a large proportion come from desserts, sugar-sweetened beverages, sweets and salty snacks," states Dr. Li. "By replacing just one of those snacks with 1.5 ounces of tree nuts may result in a positive impact on weight and overall health."

According to Maureen Ternus, M.S., R.D.N, Executive Director of the International Tree Nut Council Nutrition Research & Education Foundation (INC NREF), "This latest study adds to a growing body of evidence showing that nut consumption may be a useful tool in weight management."

 

 

Green tea compound and coconut oil may help improve depression in multiple sclerosis patients

Catholic University of Valencia (Spain), April 30. 2021

 

According to news reporting originating from Valencia, Spain, research stated, “Multiple sclerosis (MS) is pathogenically characterized by high oxidative stress and symptomatically by progressive muscle loss and increased body fat associated with the presence of depression. Epigallocatechin gallate (EGCG) (particularly present in green tea) and ketone bodies (in particular beta-hydroxybutyrate (BHB)), whose main source is coconut oil, have shown emotional benefits and body fat loss.”

The news journalists obtained a quote from the research from Catholic University of Valencia: “The aim of this study was to assess the impact of EGCG and coconut oil on cortisol activity related to fat loss and depression in MS patients. The study involved 51 MS patients who were randomly divided into an intervention group or a control group. The intervention group received 800 mg of EGCG and 60 mL of coconut oil, which were included in their daily diet for four months. The control group received placebo and all patients followed an isocaloric diet. A blood sample was collected before and after the four-month period, and levels of cortisol, albumin and BHB were measured in serum. In addition, immediately before and after the intervention, anthropometric variables were measured: waist-to-hip ratio (WHR), body fat mass percentage, fat weight, total weight, and muscle mass percentage. Depression was assessed with the Beck Depression Inventory II (BDI-II). No significant changes were obtained in cortisol levels in any of the groups, and there was a significant increase in albumin in the blood of the intervention group only that could lead to a decrease in serum free cortisol. In addition, it was observed a significant decrease in levels of depression and abdominal fat.”

According to the news reporters, the research concluded: “EGCG combined with coconut oil increase the concentration of albumin in blood and produce less depression in MS patients.”

 

 

 

Vulnerable older people at greater risk of depression and anxiety during pandemic

 

University of Manchester (UK), May 5, 2021

Older people who are clinically vulnerable to COVID-19 are at greater risk of deterioration in health and social well-being during the pandemic, according to a new study.

The research, published in the Journal of Epidemiology and Community Health, found that older people were more likely to report worse health outcomes than those with no clinical vulnerabilities, including greater depression and anxiety and lower quality of life, even when taking into account pre-pandemic levels of health and social well-being.

The findings highlight the need for policymakers to consider the mental and physical health consequences of the pandemic for those at higher risk from coronavirus, particularly for those asked to shield.

Professor Debora Price from The University of Manchester and Dr. Giorgio Di Gessa from UCL compared data from 2020's English Longitudinal Study of Aging with data from the previous year. They analyzed responses from over 5000 people aged 52 and over in private households in England.

The study revealed that during the pandemic, respondents classified as clinically vulnerable were more likely to report poor self-rated health, lower levels of physical activity, depression, anxiety, lower quality of life as well as loneliness and receipt of care, compared to those without clinical vulnerabilities.

This was true within each age group. Among people in their 70s, the odds of being depressed and anxious for those clinically vulnerable were around 50% higher than for those without clinical vulnerabilities. Those in their 80s—regardless of clinical vulnerability—were much more likely to have unmet care needs and to have little contact with friends and family by text, email, or videocall.

Although older adults' health and social well-being have been impacted by shielding, the researchers found that it was those who were clinically vulnerable and shielding who reported the most substantial rises in anxiety, depression, poor self-rated health and receipt of formal care, as well as decreases in well-being and physical activity.

"Older people with underlying health conditions, even before the pandemic, faced challenges in terms of access to healthcare services and social contact," said Professor Debora Price. "They also experienced greater emotional distress, higher risk of loneliness and poorer quality of life than non-vulnerable individuals."

"While policies focusing on shielding clinically vulnerable older people reduce rates of hospitalization and death from COVID-19, policymakers need to acknowledge that there may be adverse consequences of this measure and address the wider needs of these vulnerable groups," added Dr. Giorgio Di Gessa.

"It's vital that policymakers are aware that when advised to stay at home, a host of health and social risks for this group, already poor, are likely to be exacerbated."

 

Researchers find obesity linked to reduced blood flow to the brain

Trinity College Dublin (Ireland), May 5, 2021

A new study from scientists at The Irish Longitudinal Study on Aging (TILDA) at Trinity College Dublin reveals important findings, indicating that being overweight or obese significantly reduces blood flow in the brain. The study also shows that increased physical activity can positively modify, or even negate, this reduction in brain blood flow.

The study contains relevant information which is of great interest to the general public; since reduced blood flow in the brain, or 'cerebral hypoperfusion," is an early mechanism in vascular dementia and Alzheimer's disease.

Obesity and health challenges

According to the World Health Organization (WHO), obesity is a worsening health crisis that has reached epidemic proportions globally, with over 1 billion adults overweight—and at least 300 million clinically obese. It continues to be a major contributor to global rates of chronic disease and disability, affecting overall quality of life, while placing increased strain on the immune system which is of the upmost importance given the current COVID-19 situation. Obesity is also a significant public health concern given its negative impact on physiological function, especially as we age. Finding easily implemented and cost-effective ways to tackle the impact of obesity is particularly important to help protect against negative health outcomes in later life.

What are the findings of the TILDA study?

The study investigates three different measures of obesity—body mass index (BMI), waist-to-hip ratio and waist circumference, as well as physical activity, in adults over 50 years.

Brain blood flow was measured using cutting-edge MRI scanning and analysis techniques. The findings reveal that being overweight or obese is associated with reduced blood supply to the brain. Whereas brain blood flow is known to decline with age, in this study the negative influence of obesity on brain blood flow was shown to be greater than that of age. However, being physically active helps to cancel out the negative effects of obesity on brain blood flow.

Key Findings

  • ncreased BMI, waist-to-hip ratio, and waist size are associated with less blood supply to the brain.
  • A waist size increase of +1cm is associated with the same reduction in brain blood flow as +1 year of age.
  • Higher levels of physical activity modify the associations between reduced brain blood flow and obesity.

Recommendations

The study recommends at least 1.5 to two hours of 'being active' throughout the day, engaging in activities that require moderate effort. These include activities that cause one to breathe harder than normal, such as fast walking or cycling. However, any increase in physical activity, particularly if integrated into daily or weekly habits, such as gardening, should help maintain and potentially improve brain blood flow.

Dr. Silvin Knight, Research Fellow at TILDA and lead author, said:

Consistent, healthy blood supply to the brain is critical, as it ensures that the brain is provided with enough oxygen and nutrients to function correctly. If brain blood flow becomes impaired, it can lead to serious health issues as we age, such as increasing the risk of dementia and Alzheimer's disease. We know that obesity can predispose a person to age-related conditions, illness, and disease, and even reduce life expectancy by up to six years in men and seven years in women, after the age of forty. Our study reveals clear associations between obesity and reduced blood supply to the brain in an older population. The study also shows the importance of being physically active for older overweight or obese individuals, as this may help to protect against reduced brain blood flow and the poor health outcomes that can arise from this.

Professor Rose Anne Kenny, Principal Investigator of TILDA, and co-author of the study, said: "Many experts have shown that obesity and aging have very similar effects on the biology of aging; diseases associated with obesity are similar to those of aging and age-related diseases—heart disease, diabetes, high blood pressure, kidney failure, arthritis, susceptibility to infections- including COVID-19."

Our study not only shows that there is a link between obesity and reduced brainblood flow, but also that it is possible to protect against the negative consequences of obesity through regular physical exercise. Whereas these findings are of relevance in the global context, because of the rapidly evolving global burden of obesity, the research is especially important to Irish adults because obesity and being overweight is a considerable health issue in Ireland.

Previous TILDA research has shown that over one-third of Irish adults aged 50 and older are obese and a further 43% overweight. As we prepare our society for a growing aging population, we can use this evidence to prepare meaningful public health policies that will promote impactful and positive lifestyle habits, such as regular physical activity, to mitigate against some of the negative consequences of the growing obesity crisis.

 

 

 

 

 

In silico screening of Chinese herbal medicines with the potential to directly inhibit 2019 novel coronavirus

Shanghai Health Commission Key Lab of Artificial Intelligence (AI)-Based Management of Inflammation and Chronic Diseases, May 2, 2021

Objective

In this study we execute a rational screen to identify Chinese medical herbs that are commonly used in treating viral respiratory infections and also contain compounds that might directly inhibit 2019 novel coronavirus (2019-nCoV), an ongoing novel coronavirus that causes pneumonia.

Methods

There were two main steps in the screening process. In the first step we conducted a literature search for natural compounds that had been biologically confirmed as against sever acute respiratory syndrome coronavirus or Middle East respiratory syndrome coronavirus. Resulting compounds were cross-checked for listing in the Traditional Chinese Medicine Systems Pharmacology Database. Compounds meeting both requirements were subjected to absorption, distribution, metabolism and excretion (ADME) evaluation to verify that oral administration would be effective. Next, a docking analysis was used to test whether the compound had the potential for direct 2019-nCoV protein interaction. In the second step we searched Chinese herbal databases to identify plants containing the selected compounds. Plants containing 2 or more of the compounds identified in our screen were then checked against the catalogue for classic herbal usage. Finally, network pharmacology analysis was used to predict the general in vivo effects of each selected herb.

Results

Of the natural compounds screened, 13 that exist in traditional Chinese medicines were also found to have potential anti-2019-nCoV activity. Further, 125 Chinese herbs were found to contain 2 or more of these 13 compounds. Of these 125 herbs, 26 are classically catalogued as treating viral respiratory infections. Network pharmacology analysis predicted that the general in vivo roles of these 26 herbal plants were related to regulating viral infection, immune/inflammation reactions and hypoxia response.

Conclusion

Of course, it should be pointed out that Chinese herbs that have not been identified through this screening process may still have beneficial effects. Further, considering that the biologically validated natural compounds reported in the literature cannot cover all antiviral natural compounds, and the natural compounds included in the Chinese medicine database are not complete, the process that we have followed may have excluded herbs that would be well suited to this treatment. Nevertheless, the purpose of this screening was to provide a rational approach for selecting Chinese herbal medicines with a high potential efficacy in treating 2019-nCoV and related viruses. The specific dosage and usage of each herb should be determined based on patients’ manifestations. Finally, the key step in this screening was molecular docking. The 3D structures of the proteins used here are based on reported gene sequences. If the virus mutates during transmission, a new screening is recommended.

In conclusion, this work has identified several Chinese medicinal plants classified as antiviral/pneumonia-effective that might directly inhibit the novel coronavirus, 2019-nCoV. Additionally, we propose screening principles and methods which may provide guidance in screening antiviral drugs from other natural drug databases.

 

 

Ginkgolide B monotherapy reverses osteoporosis by regulating oxidative stress-mediated bone homeostasis

 

Chinese University of Hong Kong, May 4, 2021

According to news reporting from Hong Kong, People’s Republic of China, research stated, “Osteoporosis is characterized by reductions in bone mass, which could be attributed to the dysregulation of bone homeostasis, such as the loss of balance between bone-resorbing osteoclasts and bone-forming osteoblasts. Elevated levels of oxidative stress increase bone resorption by promoting osteoclastogenesis and inhibiting the osteogenesis.”

The news correspondents obtained a quote from the research from the Chinese University of Hong Kong, “Ginkgolide B (GB), a small natural molecule from Ginkgo biloba, has been reported to possess pharmacological activities by regulating reactive oxygen species (ROS) in aging-related degenerative diseases. Herein, we assessed the therapeutic effects of GB on the bone phenotypes of mice with osteoporosis induced by (I) aging, (II) ovariectomy, and (III) glucocorticoids. In all three animal models, oral gavage of GB significantly improved bone mass consistent with the increase in the OPG-to-RANKL ratio. In the in vitro experiments, GB promoted osteogenesis in aged mesenchymal stem cells (MSCs) and repressed osteoclastogenesis in aged macrophages by reducing ROS. The serum protein profile in GB-treated aged mice revealed moderate rejuvenating effects; signaling pathways associated with ROS were also regulated. The anabolic and anti-catabolic effects of GB were illustrated by the reduction in ROS. Our results indicate that GB is effective in treating osteoporosis.”

According to the news reporters, the research concluded: “The use of GB in patients with osteoporosis is worthy of further clinical investigation.”

This research has been peer-reviewed.

Treatment with Rhodiola mimics exercise to resist high-fat diet-induced muscle dysfunction

Central South University (China), April 30, 2021

 

According to news reporting out of Changsha, People’s Republic of China, research stated, “Muscle dysfunction is a complication of high-fat diet (HFD)-induced obesity that could be prevented by exercise, but patients did not get enough therapeutic efficacy from exercise due to multiple reasons.”

The news reporters obtained a quote from the research from Xiangya Hospital of Central South University: “To explore alternative or supplementary approaches to prevent or treat muscle dysfunction in individuals with obesity, we investigated the effects of Rhodiola on muscle dysfunction as exercise pills. SIRT1 might suppress atrogenes expression and improve mitochondrial quality control, which could be a therapeutic target stimulated by exercise and Rhodiola, but further mechanisms remain unclear. We verified the lipid metabolism disorders and skeletal muscle dysfunction in HFD feeding mice. Moreover, exercise and Rhodiola were used to intervene mice with a HFD. Our results showed that exercise and Rhodiola prevented muscle atrophy and dysfunction in obese mice and activating the SIRT1 pathway, while atrogenes were suppressed and mitochondrial quality control was improved. EX-527, SIRT1 inhibitor, was used to validate the essential role of SIRT1 in salidroside benefit.”

According to the news editors, the research concluded: “Results of cell culture experiment showed that salidroside alleviated high palmitate-induced atrophy and mitochondrial quality control impairments, but these improvements of salidroside were inhibited by EX-527 in C2C12 myotubes. Overall, Rhodiola mimics exercise that activates SIRT1 signaling leading to improvement of HFD-induced muscle dysfunction.”

 
 

Prenatal exposure to pesticides increases the risk of obesity in adolescence

First study to analyse the long-term effects of persistent organic pollutants on cardiometabolic risk in adolescents

Barcelona Institute for Global Health (Spain), May 3, 2021

Exposure before birth to persistent organic pollutants (POPs)-- organochlorine pesticides, industrial chemicals, etc.--may increase the risk in adolescence of metabolic disorders, such as obesity and high blood pressure. This was the main conclusion of a study by the Barcelona Institute for Global Health (ISGlobal), a research centre supported by the "la Caixa" Foundation. The study was based on data from nearly 400 children living in Menorca, who were followed from before birth until they reached 18 years of age. 

POPs are toxic, degradation-resistant chemicals that persist in the environment. Examples of such compounds are pesticides and organochlorine insecticides (DDT, etc.). POPs have adverse effects on both human health and the environment and their use is regulated globally.

Prenatal exposure to these substances has been associated with cardiometabolic risk factors in childhood, but there were previously no studies assessing whether such associations continue into adolescence, a developmental stage characterised by significant changes in the endocrine system and rapid increases in body mass.

The aim of this investigation, carried out within the framework of the INMA Project-Environment and Childhood, was to study the associations between prenatal exposure to POPs and body mass index (BMI) as well as other markers of cardiovascular risk in adolescence. Data from 379 children in Menorca was analysed. POP levels were measured in umbilical cord blood samples and the children were then seen periodically between the ages of 4 and 18 years. At these visits, BMI, body fat percentage and blood pressure were recorded as they grew. When the child reached 14 years of age, the scientists measured blood biomarkers of cardiometabolic risk (cholesterol, triglycerides, glucose, etc.).

The results of this study, published in the journal Environment International, suggest an association between prenatal POP exposure and a higher BMI in adolescence, particularly in the case of the fungicide hexachlorobenzene (HCB) and the insecticide compound dichloro-diphenyl-trichloroethane (DDT). 

Exposure to these two organochlorides--HCB and DDT¬--was also associated with higher blood pressure in childhood and adolescence and increased cardiometabolic risk at 14 years of age. 

ISGlobal researcher Núria Güil-Oumrait, the first author of the study, explains that "this is the first longitudinal study to analyse the relationship between persistent organic pollutants and cardiometabolic risk throughout childhood and adolescence. Our findings show that the association between these substances and infant BMI does persist into adolescence and that prenatal exposures are associated with the main risk factors for metabolic syndrome in adults, a condition that today affects one in four people worldwide.

With respect to the mechanisms that might explain this association, Güil-Oumrait points out that "it is thought that POPs may interact with hormone receptors or with the generation of free radicals, and the chief problem is that these pollutants accumulate in the fatty tissues of living organisms, where they can persist for years, even decades". 

Martine Vrijheid, study coordinator and head of the Childhood and Environment Programme at ISGlobal, highlights the fact that "some of these substances could be considered endocrine disruptors, that is, chemicals that interfere with hormonal regulation". In her view "more studies are needed in this field, especially focussing on childhood and adolescence, which are critical developmental stages characterised by particular vulnerability".

 

 

One cup of leafy green vegetables a day lowers risk of heart disease

Research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.

Edith Cowan University (Australia), May 4, 2021

New Edith Cowan University (ECU) research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.

The study investigated whether people who regularly ate higher quantities of nitrate-rich vegetables, such as leafy greens and beetroot, had lower blood pressure, and it also examined whether these same people were less likely to be diagnosed with heart disease many years later.

Cardiovascular diseases are the number one cause of death globally, taking around 17.9 million lives each year.

Researchers examined data from over 50,000 people residing in Denmark taking part in the Danish Diet, Cancer, and Health Study over a 23-year period. They found that people who consumed the most nitrate-rich vegetables had about a 2.5 mmHg lower systolic blood pressure and between 12 to 26 percent lower risk of heart disease.

Lead researcher Dr Catherine Bondonno from ECU's Institute for Nutrition Research said identifying diets to prevent heart disease was a priority.

"Our results have shown that by simply eating one cup of raw (or half a cup of cooked) nitrate-rich vegetables each day, people may be able to significantly reduce their risk of cardiovascular disease," Dr Bondonno said.

"The greatest reduction in risk was for peripheral artery disease (26 percent), a type of heart disease characterised by the narrowing of blood vessels of the legs, however we also found people had a lower risk of heart attacks, strokes and heart failure." 

Forget the supplements

The study found that the optimum amount of nitrate-rich vegetables was one cup a day and eating more than that didn't seem to give any additional benefits.

"People don't need to be taking supplements to boost their nitrate levels because the study showed that one cup of leafy green vegetables each day is enough to reap the benefits for heart disease," Dr Bondonno said.

"We did not see further benefits in people who ate higher levels of nitrate rich vegetables."

Smoothies are ok

Dr Bondonno said hacks such as including a cup of spinach in a banana or berry smoothie might be an easy way to top up our daily leafy greens.

"Blending leafy greens is fine, but don't juice them. Juicing vegetables removes the pulp and fibre," Dr Bondonno said.

The paper "Vegetable nitrate intake, blood pressure and incident cardiovascular disease: Danish Diet, Cancer, and Health Study" is published in the European Journal of Epidemiology. It is a collaboration between Edith Cowan University, the Danish Cancer Society and The University of Western Australia.

The research adds to growing evidence linking vegetables generally and leafy greens specifically with improved cardiovascular health and muscle strength. This evidence includes two recent ECU studies exploring cruciferous vegetables and blood vessel health and green leafy vegetables and muscle strength.

 

 

Mindfulness programs can boost children's mental health

 

University of Derby (UK), May 4, 2021

Mindfulness programs can improve the mental health of school-age children and help them to feel more optimistic, according to new research from the University of Derby and Derbyshire Educational Psychology Service.

More than 1,000 pupils aged between 9-12 years old across 25 schools in Derbyshire, received one 45-minute mindfulness session per week for nine weeks during the year-long project, which involved a collaboration between Dr. William Van Gordon, Associate Professor in Contemplative Psychology at the University, and Derbyshire Educational Psychology Service.

Mindfulness is an ancient meditation technique that involves focussing awareness on the present moment, as a means of fostering calm, wellbeing and insight. The weekly sessions involved activities such as practicing mindful breathing and paying attention to bodily sensations, as well as exercises intended to help cultivate attention skills and a greater awareness of emotions.

The impact of the sessions, which were delivered by teachers in a traditional classroom environment, was evaluated by comparing psychological assessments that the children completed before the classes began, with assessments undertaken after the program had concluded. Part of the evaluation measured children's emotional resiliency using The Resiliency Scale for Children, while wellbeing was rated using the Stirling Children's Wellbeing Scale.

Overall, the study found a significant improvement in positive emotional state, outlook and resiliency. There was also an increase in the different dimensions of resilience: optimism increased by 10%, tolerance was improved by 8% and self-efficacy, how a child feels they can cope with a situation based on the skills they have and the circumstances they face, improved by 11%.

Professor Van Gordon said: "Findings from the study indicate that mindfulness delivered by school teachers can improve wellbeing and resiliency in children and young people.

"This is consistent with wider evidence demonstrating the positive impact of mindfulness on school children's levels of emotional resiliency, emotional stability, wellbeing and stress.

"These findings are also in line with the view that preventative interventions given at a young age can help to reduce the incidence of mental health problems in young people."

 

Vitamin D levels higher in exercisers

Johns Hopkins University, May 01 2021 

The issue of the Journal of Clinical Endocrinology & Metabolism published the finding of researchers at Johns Hopkins University of a correlation between increased physical activity and higher levels of vitamin D. Higher levels of vitamin D and exercise was also associated with a lower risk of cardiovascular disease.

The study included 10,342 men and women who were free of coronary heart disease and heart failure upon enrollment in the Atherosclerosis Risk in Communities study. Physical activity levels were assessed during follow-up visits that took place over a 19.3-year period. Stored serum samples obtained at the second visit were analyzed for 25-hydroxyvitamin D3.

Subjects who achieved American Heart Association recommended physical activity levels had average levels of vitamin D that were higher than those who had intermediate and poor levels of activity. Following adjustment for lifestyle and other factors, those who met the recommended levels had a 31% lower risk of being deficient in vitamin D than those with poor activity levels. Subjects in the recommended activity group with levels of vitamin D of 30 ng/mL or more had a 24% lower risk of cardiovascular disease.

The association between exercise and vitamin D was stronger in subjects of European ethnicity than among African Americans. The authors noted that European-Americans as well as those who engage in exercise are likelier to be supplement users. “We did find that vitamin D supplement use was higher among those with increased physical activity,” they observed.

"In our study, both failure to meet the recommended physical activity levels and having vitamin D deficiency were very common" stated coauthor Erin Michos, MD, MS, of Johns Hopkins University School of Medicine. "The bottom line is we need to encourage people to move more in the name of heart health."

 

 

One teaspoon daily of trehalose can help maintain glucose homeostasis: a double-blind, randomized controlled trial 

Hayashibara Co. Ltd (Japan), April 24, 2021

Background

Trehalose is a natural disaccharide that is widely distributed. A previous study has shown that daily consumption of 10 g of trehalose improves glucose tolerance in individuals with signs of metabolic syndrome. In the present study, we determined whether a lower dose (3.3 g/day) of trehalose improves glucose tolerance in healthy Japanese volunteers.

Methods

This was a randomized, double-blind, placebo-controlled study of healthy Japanese participants (n = 50). Each consumed 3.3 g of trehalose (n = 25) or sucrose (n = 25) daily for 78 days. Their body compositions were assessed following 0, 4, 8, and 12 weeks; and serum biochemical parameters were assayed and oral 75-g glucose tolerance tests were performed at baseline and after 12 weeks.

Results

There were similar changes in body composition and serum biochemistry consistent with established seasonal variations in both groups, but there were no differences in any of these parameters between the two groups. However, whereas after 12 weeks of sucrose consumption, the plasma glucose concentration 2 h after a 75-g glucose load was significantly higher than the fasting concentration, after 12 weeks of trehalose consumption the fasting and 2-h plasma glucose concentrations were similar. Furthermore, an analysis of the participants with relatively high postprandial blood glucose showed that the plasma glucose concentration 2 h after a 75-g glucose load was significantly lower in the trehalose group than in the sucrose group.

Conclusions

Our findings suggest that trehalose helps lower postprandial blood glucose in healthy humans with higher postprandial glucose levels within the normal range, and may therefore contribute to the prevention of pathologies that are predisposed to by postprandial hyperglycemia,, even if the daily intake of trehalose is only 3.3 g, an amount that is easily incorporated into a meal.

 

 

Coffee compound enhances autophagy to protect against cell injury

Chengdu University of Traditional Chinese Medicine (China), April 30, 2021

According to news reporting originating from Sichuan, People’s Republic of China, research stated, “Autophagy serves an important role in amyloid-beta (A beta) metabolism and tau processing and clearance in Alzheimer’s disease. The progression of A beta plaque accumulation and hyperphosphorylation of tau proteins are enhanced by oxidative stress.”

Our news editors obtained a quote from the research from the Chengdu University of Traditional Chinese Medicine, “A hydrogen peroxide (H2O2) injury cell model was established using SH-SY5Y cells. Cells were randomly divided into normal, H2O2 and chlorogenic acid (5-caffeoylquinic acid; CGA) groups. The influence of CGA on cell viability was evaluated using a Cell Counting Kit-8 assay and cell death was assessed using Hoechst 33342 nuclear staining. Autophagy induction and fusion of autophagic vacuoles assays were performed using monodansylcadaverine staining. Additionally, SH-SY5Y cells expressing Ad-mCherry-green fluorescent protein-LC3B were established to detect autophagic flow. LysoTracker Red staining was used to evaluate lysosome function and LysoSensor ™ Green staining assays were used to assess lysosomal acidification. The results demonstrated that CGA decreased the apoptosis rate, increased cell viability and improved cell morphology in H2O2-treated SH-SY5Y cells. Furthermore, CGA alleviated the accumulation of autophagic vacuoles, reduced the LC3BII/I ratio and decreased P62 levels, resulting in increased autophagic flux. Additionally, CGA upregulated lysosome acidity and increased the expression levels of cathepsin D. Importantly, these effects of CGA on H2O2-treated SH-SY5Y cells were mediated via the mTOR-transcription factor EB signaling pathway.”

According to the news editors, the research concluded: “These results indicated that CGA protected cells against H2O2-induced oxidative damage via the upregulation of autophagosomes, which promoted autophagocytic degradation and increased autophagic flux.”

This research has been peer-reviewed.

Lycopene is a promising nutrient that can prevent gastric diseases associated with H. pylori

Yonsei University (Japan), April 30, 2021

Helicobacter pylori is a spiral-shaped bacterium that grows in your digestive tract. An opportunistic pathogen, it is considered to be the most successful colonizer of the human gastrointestinal tract, infecting the stomachs of roughly 60 percent of the world’s adult population.

In a recent study, researchers at Yonsei University in South Korea found that lycopene, a bioactive pigment with powerful antioxidant properties, can help prevent gastric diseases associated with H. pylori infection. Lycopene is a non-provitamin A carotenoid commonly found in bright red and orange produce, such as tomatoes, watermelons, papaya and pink grapefruit. This beneficial compound is extensively studied for its remarkable ability to scavenge free radicals, the unstable byproducts of cellular metabolism responsible for causing oxidative stress.

How lycopene prevents H. pylori-induced gastric cancer

According to studies, H. pylori infection promotes the hyperproliferation of gastric epithelial cells — the very cells that make up the stomach lining — by increasing the production of free radicals called reactive oxygen species (ROS). ROS then activates two signaling pathways — Wnt/B-catenin and JAK1/Stat3 — that influence cell fate decisions. While Wnt/B-catenin signaling is involved in the regulation of the self-renewal processes of cells, JAK1/Stat3 signaling is said to play a role in conferring malignant properties to cancer cells.

Due to the involvement of ROS, the South Korean researchers hypothesized that lycopene, which has antioxidant and anti-cancer properties, may be able to suppress H. pylori-induced hyperproliferation by inhibiting the activation of Jak1/Stat3 and Wnt/B-catenin signaling, as well as the expression of B-catenin target genes. B-catenin is a protein that accumulates due to the aberrant activation of Wnt/B-catenin signaling. The buildup of this protein promotes the expression of cancer genes (oncogenes) and the progression of tumors.

In an earlier study published in The American Journal of Clinical Nutrition, German researchers reported that lycopene is the most effective scavenger of singlet oxygen, a very strong oxidant and one of the major ROS produced by cells. To determine if it can prevent ROS-mediated hyperproliferation, South Korean researchers treated H. pylori-infected gastric epithelial cells with lycopene.  They measured the cells’ ROS levels and viability before and after treatment.

The researchers found that lycopene effectively reduced ROS levels and inhibited not only the activation of Jak1/Stat3 and Wnt/B-catenin signaling but also the expression of B-catenin target oncogenes and the proliferation of H. pylori-infected gastric epithelial cells. In addition, lycopene inhibited the increase in Wnt-1 (an oncogenic protein) and lipoprotein-related protein 5 (a protein involved in cancer progression) expression caused by H. pylori infection.

Based on these findings, the researchers concluded that lycopene can be used to prevent H. pylori-associated gastric cancer, thanks to its inhibitory effects on gastric cell hyperproliferation.

 

Too much salt suppresses phagocytes

Max Delbrück Center for Molecular Medicine (Germany), May 4, 2021

For many of us, adding salt to a meal is a perfectly normal thing to do. We don't really think about it. But actually, we should. As well as raising our blood pressure, too much salt can severely disrupt the energy balance in immune cells and stop them from working properly.

Back in 2015, the research group led by Professor Dominik Müller of the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) and the Experimental and Clinical Research Center (ECRC) found that elevated sodium concentrations in the blood affect both the activation and the function of patrolling monocytes, which are the precursors to macrophages. "But we didn't know exactly what was happening in the cells," says Dr. Sabrina Geisberger of the Berlin Institute for Medical Systems Biology (BIMSB) at the MDC. She is lead author of the study of an international research team led by MDC scientists together with colleagues from University of Regensburg and from Flanders Institute for Biotechnology (VIB) /Hasselt University in Belgium. It was funded by the German Center for Cardiovascular Research (DZHK) and has now been published in the journal Circulation

Salt disrupts the respiratory chain in cells

Working with biochemist and metabolomics expert Dr. Stefan Kempa of BIMSB, the researchers began in the lab by looking at the metabolism of immune cells that had been exposed to high salt concentrations. Changes appeared after just three hours. "It disrupts the respiratory chain, causing the cells to produce less ATP and consume less oxygen," explains Geisberger. ATP (adenosine triphosphate) is the universal fuel that powers all cells. It provides energy for the "chemical work" - synthesizing proteins and other molecules - required for muscle power and metabolic regulation. ATP is produced in the mitochondria, the cell's "power plant," using a complex series of biochemical reactions known as the respiratory chain. "Salt very specifically inhibits complex II in the respiratory chain."

This has consequences: The lack of energy causes the monocytes to mature differently. "The phagocytes, whose task is to identify and eliminate pathogens in the body, were able to fight off infections more effectively. But this could also promote inflammation, which might increase cardiovascular risk," explains Müller. 

Effects of salt are reversible

Professor Markus Kleinewietfeld of Hasselt University and VIB, and Professor Jonathan Jantsch of Universität Regensburg, were heavily involved in the work investigating human monocytes and macrophages. They were able to show that salt affects the functioning of human phagocytes in the same way.

Researchers at the ECRC, which is run jointly by the MDC and Charité - Universitätsmedizin Berlin, then conducted a study in which healthy male participants supplemented their usual diets with six grams of salt in tablet form every day for 14 days. In another clinical study, the researchers investigated a familiar scenario: eating a pizza delivered by an Italian restaurant. They then analyzed the monocytes in the participants' blood. The findings showed that the dampening effect on mitochondria doesn't just occur after an extended period of increased salt intake - it also happens after a single pizza. Data from the pizza experiment showed how long the effect lasted: Blood was taken from the participants after three and eight hours, and the effect was barely measurable in the second sample.

"That's a good thing. If it had been a prolonged disturbance, we'd be worried about the cells not getting enough energy for a long time," says Müller. The mitochondrial activity is therefore not permanently inhibited. That said, the continuous risk of sodium on mitochondrial function if a person eats very salty food several times a day cannot be ruled out, but needs to be tested in the future. The pizza, incidentally, contained ten grams of salt. Nutrition experts recommend that adults limit their daily intake to five or six grams at most. The calculation includes the salt that is hidden in processed foods.

Small ion, big effect

"The fundamental finding of our study is that a molecule as small as the sodium ion can be extremely efficient at inhibiting an enzyme that plays a crucial role in the respiratory chain," says Kempa. "When these ions flood into the mitochondria - and they do this under a variety of physiological conditions - they regulate the central part of the electron transport chain." It therefore appears to be a very fundamental regulatory mechanism in cells.

Now the task is to investigate whether salt can also influence this mechanism in other types of cells. Kleinewietfeld believes that this is extremely likely because mitochondria aren't just present in immune cells; with the exception of red blood cells, they exist in every cell of the body. They can be found in particularly high numbers wherever a lot of energy is consumed - in muscle cells, neurons, receptors, and egg cells. 

It is still not fully elucidated how different cell types regulate the influx of sodium into the mitochondria. Nevertheless, the study confirms that consuming too much salt can be bad for our health. "Of course the first thing you think of is the cardiovascular risk. But multiple studies have shown that salt can affect immune cells in a variety of ways. If such an important cellular mechanism is disrupted for a long period, it could have a negative impact - and could potentially drive inflammatory diseases of the blood vessels or joints, or autoimmune diseases," says Kleinewietfeld.

 

 

Ginkgo biloba extract improves cognitive function and increases neurogenesis by reducing amyloid beta pathology 

Xuzhou Medical University (China), May 1, 2021

According to news reporting from Jiangsu, People’s Republic of China, research stated, “Previous studies have indicated that the generation of newborn hippocampal neurons is impaired in the early phase of Alzheimer’s disease (AD). A potential therapeutic strategy being pursued for the treatment of AD is increasing the number of newborn neurons in the adult hippocampus.”

The news correspondents obtained a quote from the research from Xuzhou Medical University, “Recent studies have demonstrated that ginkgo biloba extract (EGb 761) plays a neuroprotective role by preventing memory loss in many neurodegenerative diseases. However, the extent of EGb 761’s protective role in the AD process is unclear. In this study, different doses of EGb 761 (0, 10, 20, and 30 mg/kg; intraperitoneal injections once every day for four months) were tested on 5xFAD mice. After consecutive 4-month injections, mice were tested in learning memory tasks, A beta, and neurogenesis in the dentate gyrus (DG) of hippocampus and morphological characteristics of neurons in DG of hippocampus. Results indicated that EGb 761 (20 and 30 mg/kg) ameliorated memory deficits. Further analysis indicated that EGb 761 can reduce the number of A beta positive signals in 5xFAD mice, increase the number of newborn neurons, and increase dendritic branching and density of dendritic spines in 5xFAD mice compared to nontreated 5xFAD mice.”

According to the news reporters, the research concluded: “It was concluded that EGb 761 plays a protective role in the memory deficit of 5xFAD mice.”

This research has been peer-reviewed.

 

 

Fasting lowers blood pressure by reshaping the gut microbiota

Baylor College of Medicine, April 30 2021

Nearly half of adults in the United States have hypertension, a condition that raises the risk for heart disease and stroke, which are leading causes of death in the U. S.

At Baylor College of Medicine, Dr. David J. Durgan and his colleagues are dedicated to better understand hypertension, in particular the emerging evidence suggesting that disruption of the gut microbiota, known as gut dysbiosis, can have adverse effects on blood pressure.

"Previous studies from our lab have shown that the composition of the gut microbiota in animal models of hypertension, such as the SHRSP (spontaneously hypertensive stroke-prone rat) model, is different from that in animals with normal blood pressure," said Durgan, assistant professor of anesthesiology at Baylor.

The researchers also have shown that transplanting dysbiotic gut microbiota from a hypertensive animal into a normotensive (having a healthy blood pressure) one results in the recipient developing high blood pressure.

"This result told us that gut dysbiosis is not just a consequence of hypertension, but is actually involved in causing it," Durgan said. "This ground work led to the current study in which we proposed to answer two questions. First, can we manipulate the dysbiotic microbiota to either prevent or relieve hypertension? Second, how are the gut microbes influencing the animal's blood pressure?"

Can manipulating the gut microbiota regulate blood pressure?

To answer the first question, Durgan and his colleagues drew on previous research showing that fasting was both one of the major drivers of the composition of the gut microbiota and a promoter of beneficial cardiovascular effects. These studies, however, had not provided evidence connecting the microbiota and blood pressure.

Working with the SHRSP model of spontaneous hypertension and normal rats, the researchers set up two groups. One group had SHRSP and normal rats that were fed every other day, while the other group, called control, had SHRSP and normal rats with unrestricted food availability.

Nine weeks after the experiment began, the researchers observed that, as expected, the rats in the SHRSP control had higher blood pressure when compared to the normal control rats. Interestingly, in the group that fasted every other day, the SHRSP rats had significantly reduced blood pressure when compared with the SHRSP rats that had not fasted.

"Next, we investigated whether the microbiota was involved in the reduction of blood pressure we observed in the SHRSP rats that had fasted," Durgan said.

The researchers transplanted the microbiota of the rats that had either fasted or fed without restrictions into germ-free rats, which have no microbiota of their own.

Durgan and his colleagues were excited to see that the germ-free rats that received the microbiota of normally fed SHRSP rats had higher blood pressure than the germ-free rats receiving microbiota from normal control rats, just like their corresponding microbiota donors.

"It was particularly interesting to see that the germ-free rats that received microbiota from the fasting SHRSP rats had significantly lower the blood pressure than the rats that had received microbiota from SHRSP control rats," Durgan said. "These results demonstrated that the alterations to the microbiota induced by fasting were sufficient to mediate the blood pressure-lowering effect of intermitting fasting."

How the microbiota regulates blood pressure

The team proceeded to investigate the second question of their project. How does the gut microbiota regulate blood pressure?

"We applied whole genome shotgun sequence analysis of the microbiota as well as untargeted metabolomics analysis of plasma and gastrointestinal luminal content. Among the changes we observed, alterations in products of bile acid metabolism stood out as potential mediators of blood pressure regulation," Durgan said.

The team discovered that the SHRSP hypertensive animals that were fed normally had lower bile acids in circulation than normotensive animals. On the other hand, SHRSP animals that followed an intermittent feeding schedule had more bile acids in the circulation.

"Supporting this finding, we found that supplementing animals with cholic acid, a primary bile acid, also significantly reduced blood pressure in the SHRSP model of hypertension," Durgan said.

Taken together, the study shows for the first time that intermittent fasting can be beneficial in terms of reducing hypertension by reshaping the composition of gut microbiota in an animal model. The work also provides evidence that gut dysbiosis contributes to hypertension by altering bile acid signaling.

"This study is important to understand that fasting can have its effects on the host through microbiota manipulation," Durgan said. "This is an attractive idea because it can potentially have clinical applications. Many of the bacteria in the gut microbiotaare involved in the production of compounds that have been shown to have beneficial effects as they make it into the circulation and contribute to the regulation of the host's physiology. Fasting schedules could one day help regulate the activity of gut microbial populations to naturally provide health benefits.

 

Study: Following healthy diets found to reduce the risk of acquired hearing loss by 30%

Brigham and Women's Hospital, April 30, 2021

A study published in the American Journal of Epidemiology suggests that following a healthy diet may help ward off acquired hearing loss. A team led by Brigham and Women’s Hospital researchers examined middle-aged women and found that the odds of developing hearing loss is 30 percent lower in those who adhere to a healthy diet.

Adherence to a healthy diet linked to lower risk of hearing loss

Acquired hearing loss refers to the total or partial inability to hear sounds that develop after birth. It occurs for various reasons, including ear infection, meningitis, measles, head injury, exposure to loud noise and aging.

Past studies linked higher intake of certain nutrients such as beta-carotene (found in carrots, legumes and other foods) and omega-3 fatty acids (found in fatty fish) to a lower risk of self-reported hearing loss. The researchers wished to learn more about this connection by tracking people’s diets and measuring changes in their hearing sensitivity over a long period of time.

To do so, the researchers studied 20 years of dietary intake information from over 3,000 women with a median age of 59 who were included in the Nurses’ Health Study II. Using this information, they examined how closely the women’s long-term diets resembled the Alternate Mediterranean diet (AMED), Dietary Approaches to Stop Hypertension (DASH diet) and Alternate Healthy Index-2010 (AHEI-2010). 

AMED is a version of the Mediterranean diet adapted to reflect eating patterns that are linked to a lower risk of chronic disease, while the DASH diet is intended to control and prevent high blood pressure. On the other hand, AHEI-2010 is based on the 2010 U.S. Department of Agriculture’s Dietary Guidelines for Americans and shares similar components with AMED and the DASH diet.

Past studies linked adherence to these diets to a lower risk of heart disease, stroke, diabetes, hypertension and premature death.

To measure the participants’ hearing sensitivity over the course of three years, the team put up 19 testing sites across the country and trained audiologists to measure changes in the participants’ pure-tone hearing thresholds – the lowest and highest pitch (frequency of a sound) that a person can detect in one ear.

The researchers found that the odds of hearing loss in the mid-frequencies were nearly 30 percent lower in the women whose dietary patterns resembled the three diets, compared to those whose diets least resembled them. Meanwhile, the odds of hearing loss in higher frequencies were up to 25 percent lower. The frequencies encompassed in these associations, according to the researchers, are critical for speech understanding.

“We were surprised that so many women demonstrated hearing decline over such a relatively short period of time,” said Sharon Curhan, a professor of medicine at Harvard Medical School and the lead researcher of the study.

After only three years, nineteen percent of the participants had low-frequency hearing loss, 38 percent had mid-frequency hearing loss, while nearly half had high-frequency hearing loss. (Related: Age-related hearing loss halted with folate nutrient.)

“The mean age of the women in our study was 59 years; most of our participants were in their 50s and early 60s. This is a younger age than when many people think about having their hearing checked,” she added.

The researchers plan to continue tracking the participants with repeated hearing tests and are currently investigating ways to collect high-quality information for future studies across diverse populations.

 

Thai ginseng found to improve erectile function in men

Life Extension Foundation, April 28, 2021

American researchers examined the effects of an ethanol extract derived from Kaempferia parviflora, also known as Thai ginseng, on erectile function in healthy middle-aged and older men. Their findings were published in the Journal of Integrative Medicine.

  • Sexual health positively correlates with overall well-being.
  • Current strategies that are meant to enhance male sexual health are limited by many factors, such as responsiveness, adherence and adverse effects.
  • Researchers understand the need for safe and effective interventions that could help preserve male sexual function.
  • K. parviflora, a plant from the Zingiberaceae (ginger) family, has been found to support cardiovascular health and has shown signs that it could ameliorate erectile dysfunction.
  • To investigate this, the researchers conducted an open-label, one-arm study involving 14 generally healthy males aged 50 to 68 years with self-reported mild erectile dysfunction.
  • The participants received 100 mg of an extract obtained from the rhizome of K. parviflora daily for 30 days.
  • Primary efficacy analyses included the International Index of Erectile Function (IIEF), while secondary efficacy analyses included the Global Assessment Question about erectile function.
  • The researchers reported that 13 of the 14 participants completed the study. Supplementation of the K. parviflora ethanol extract induced statistically significant improvements in erectile function, intercourse satisfaction and total scores on IIEF questionnaire.
  • The extract was well-tolerated by the participants and exhibited an excellent safety profile.

Based on these findings, the researchers concluded that K. parviflora can improve erectile function in healthy middle-aged and older men.

 

 

Curcumin Reduces Anxiety and Depression Even In People With Major Depression


Texas Christian University and University of Arkansas, May 1, 2021

 

Dietary supplements formulated with highly bioavailable curcumin may allow for faster recovery after competition-level training, and blunt training-related decreases in performance , says new data presented at Experimental Biology.

 

Powdered turmeric has been used for centuries to treat a host of illnesses. It inhibits inflammatory reactions, has anti-diabetic effects, reduces cholesterol among other powerful healtheffects. A recent study led by a research team in Munich showed that it can also inhibit formation of metastases

Dietary supplements formulated with highly bioavailable curcumin may allow for faster recovery after competition-level training, and blunt training-related decreases in performance , says new data presented at Experimental Biology.

Using OmniActive's supplement ingredient, scientists reported that supplementation for eight weeks resulted in significant reductions in levels of creatine kinase, a marker of muscle damage, while self-reported pain scores were also significantly lower 24 hours post-exercise.

A daily 200 mg dose of curcuminoids (in the form of 1,000 mg supplement) was also associated with a decrease in performance declines observed during

"These data suggest that high dose bioavailable curcumin (200 mg curcuminoids) attenuates performance decrements following downhill running, eccentric loading, which may improve subsequent adaptations to chronic training," wrote the researchers in the FASEB Journal .

Dr Ralf Jager from Wisconsin-based Increnovo and co-author on the study reports, explained that curcumin's sports nutrition benefits were linked to its antioxidant and anti-inflammatory potential.

Muscle Damage Study

The researchers recruited 59 moderately trained men and 29 women with an average age of 21 to participate in their double-blind, randomized, placebo controlled parallel design study. The participants were randomly assigned to receive 250 mg or 1,000 mg of supplement or placebo per day for eight weeks.

The data indicated that, following muscle-damaging exercise, the high dose curcumin group experienced significantly lower pain scores, while increases in creatine kinase (CK) levels were also significantly reduced compared to placebo, when the baseline CK value is held constant at the mean.

"These data demonstrate curcuminoids reduce muscle damage and improve muscle soreness in healthy young subjects following a bout of muscle damaging exercise. Faster recovery allows for consistent training at competition intensity and might lead to enhanced adaptation rate and performance," they wrote in the FASEB Journal .

Performance

A separate analysis was done with 62 men and women randomly assigned to 250 mg or 1,000 mg of supplement per day or placebo. After eight weeks the subjects performced downhill running, which promotes muscle damage.

The results showed that performance declined significantly in both the placebo and low-dose curcumin group, but such declined were attenuated in the high-dose curcumin group.

"Further study is warranted in other exercise types (i.e. resistance training) and chronically," wrote the researchers.

  1. Avocado discovery may point to leukemia treatment

    University of Guelph (Canada), May 1, 2021

    A compound in avocados may ultimately offer a route to better leukemia treatment, says a new University of Guelph study.

    The compound targets an enzyme that scientists have identified for the first time as being critical to cancer cell growth, said Dr. Paul Spagnuolo, Department of Food Science.

    Published recently in the journal Blood, the study focused on acute myeloid leukemia (AML), which is the most devastating form of leukemia. Most cases occur in people over age 65, and fewer than 10 per cent of patients survive five years after diagnosis.

    Leukemia cells have higher amounts of an enzyme called VLCAD involved in their metabolism, said Spagnuolo.

    “The cell relies on that pathway to survive,” he said, explaining that the compound is a likely candidate for drug therapy. “This is the first time VLCAD has been identified as a target in any cancer.”

    His team screened nutraceutical compounds among numerous compounds, looking for any substance that might inhibit the enzyme. “Lo and behold, the best one was derived from avocado,” said Spagnuolo.

    Earlier, his lab looked at avocatin B, a fat molecule found only in avocados, for potential use in preventing diabetes and managing obesity. Now he’s eager to see it used in leukemia patients.

    “VLCAD can be a good marker to identify patients suitable for this type of therapy. It can also be a marker to measure the activity of the drug,” said Spagnuolo. “That sets the stage for eventual use of this molecule in human clinical trials.”

    Currently, about half of patients over 65 diagnosed with AML enter palliative care. Others undergo chemotherapy, but drug treatments are toxic and can end up killing patients.

    “There’s been a drive to find less toxic drugs that can be used.”

    Referring to earlier work using avocatin B for diabetes, Spagnuolo said, “We completed a human study with this as an oral supplement and have been able to show that appreciable amounts are fairly well tolerated.”

    Supplement betaine treats schizophrenia in mice, restores healthy “dance” and structure of neurons

    University of Tokyo Graduate School of Medicine, April 19, 2021

    A simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia. After additional experiments, including visualizing the fluorescently stained dancing edge of immature brain cells, researchers concluded that the supplement likely protects proteins that build neurons’ cellular skeletons.

    The supplement betaine was first isolated from sugar beets and is often associated with sweetness or umami flavor. Healthy levels of betaine come from both external food sources and internal synthesis in the body. Betaine supplements are already used clinically to treat the metabolic disease homocystinuria. 

    “I don’t encourage anyone to take betaine for no reason, if a doctor has not recommended it. But, we know this drug is already used clinically, so repurposing it to treat schizophrenia should be safe,” said Project Professor Nobutaka Hirokawa, M.D., Ph.D., from the University of Tokyo Graduate School of Medicine who led the recent research project. Hirokawa has been a member of the Japan Academy, a national honorary organization recognizing scientific achievement, since 2004 and received a Person of Cultural Merit award from the Japanese government in 2013.

    Schizophrenia is estimated to affect about 1 in 100 people globally and is one of the top 15 leading causes of disability worldwide. 

    “There are treatments for schizophrenia, but they have side effects and unfortunately there is still no effective drug for patients to take that we can explain biochemically why it works,” explained Hirokawa.

    Genetic studies of people diagnosed with schizophrenia have found possible links between the disease and variations in the kinesin family 3b (kif3b) gene as well as another gene involved in the body’s internal synthesis of betaine.

    Hirokawa and his lab members have categorized all 45 members of the kinesin superfamily of genes in mammals, most of which encode motor proteins that move materials throughout the cell. Normally, the KIF3B protein links together with another kinesin superfamily protein and transports cargo throughout a neuron by traveling up and down the cell’s skeleton. 

    Mice used in the recent research had only one functional copy of the kif3b gene and are often used as an animal model of schizophrenia. These mice avoid social interactions and show the same weak response as human patients with schizophrenia in a test called prepulse inhibition, which measures how startled they are by a sudden, loud sound preceded by a quieter sound.

    Kif3b mutant mice raised on a diet supplemented with three times the normal amount of betaine had normal behavior, indicating that betaine supplements could treat schizophrenia symptoms. 

    To figure out why betaine had this effect on mice, researchers grew nerve cells with the kif3b mutation in the laboratory and added fluorescent labels so they could watch the cellular skeleton take shape.

    The shape of a healthy neuron is reminiscent of a tree: a cell body surrounded by branches, the dendrites, attached to a long trunk, the axon. Kif3b mutant neurons grown in the lab have an unusual, hyperbranched structure with too many dendrites. Similar hyperbranched neurons are also seen in brain samples donated by people with schizophrenia, regardless of what treatments or medications they took while they were alive. 

    During healthy neuron development, the main body of the cell fills with a skeleton component called tubulin. Meanwhile, the front growth cone of the cell builds outwards in a spiky, erratic dance due to the movements of another skeleton component called filamentous actin. In kif3b mutants, this dancing movement, which experts refer to as lamellipodial dynamics, is noticeably reduced and the division between tubulin and actin is blurred. 

    The actin in a neuron’s cellular skeleton is assembled in part by another protein called CRMP2. Chemical analyses of the brains of kif3b mutant mice and human schizophrenia patients reveal significant chemical damage to CRMP2, which causes the proteins to clump together.

    Betaine is known to prevent the type of chemical damage, carbonyl stress, that causes this CRMP2 dysfunction. 

    “In postmortem brains of schizophrenia patients, CRMP2 is the protein in the brain with the most carbonyl stress. Betaine likely eliminates the carbonyl stress portion of the schizophrenia equation,” said Hirokawa. 

    By protecting CRMP2 from damage, betaine treatment allows kif3b mutant neurons to build proper structures. With a structurally sound skeleton to navigate, the remaining functional KIF3B protein can shuttle cargo around the cell. Other test tube experiments revealed that KIF3B and CRMP2 can bind together, but their exact relationship remains unclear. 

    “We know that the amount of betaine decreases in schizophrenia patients’ brains, so this study strongly suggests betaine could be therapeutic for at least some kinds of schizophrenia,” said Hirokawa. 

    The UTokyo research team is planning future collaborations with pharmaceutical companies and clinical studies of betaine supplements as a treatment for schizophrenia.

    Study reveals your neighbourhood may affect your brain health

    University of Wisconsin School of Medicine, April 20, 2021

    Middle-aged and older people living in more disadvantaged neighbourhoods — areas with higher poverty levels and fewer educational and employment opportunities–had more brain shrinkage on brain scans and showed a faster decline on cognitive tests than people living in neighbourhoods with fewer disadvantages, according to a new study.

    The study published in the online issue of Neurology, the medical journal of the American Academy of Neurology. Researchers say such brain ageing may be a sign of the earliest stages of dementia.

    “Worldwide, dementia is a major cause of illness and a devastating diagnosis,” said study author Amy J. H. Kind M.D., PhD, of the University of Wisconsin School of Medicine and Public Health in Madison.

    “There are currently no treatments to cure the disease, so identifying possible modifiable risk factors is important. Compelling evidence exists that the social, economic, cultural and physical conditions in which humans live may affect health. We wanted to determine if these neighbourhood conditions increase the risk for the neurodegeneration and cognitive decline associated with the earliest stages of Alzheimer’s disease and dementia.”

    For the study, researchers identified 601 people from two larger studies of Wisconsin residents. Participants had an average age of 59 and no thinking or memory problems at the start of the study, although 69% had a family history of dementia. They were followed for 10 years.

    Participants had an initial MRI brain scan and then additional scans every three to five years. With each scan, researchers measured brain volume in areas of the brain linked to the development of Alzheimer’s dementia. Participants also took thinking and memory tests every two years, including tests that measured processing speed, mental flexibility and executive function.

    Researchers used the residential address of each participant and a measure called the Area Deprivation Index to determine if each participant lived in an advantaged or disadvantaged neighbourhood. Neighbourhoods in the index are determined by census areas of 1,500 residents. The index incorporates information on the socio-economic conditions of each neighbourhood and its residents, ranking neighbourhoods based on 17 indicators including income, employment, education and housing quality.

    Of all participants, 19 people lived in the 20% of most disadvantaged neighbourhoods in their state and 582 people lived in 80% of all other neighbourhoods in their state. People in the first group were then matched one to four to people in the second group for race, sex, age and education and compared.

    At the start of the study, there was no difference in brain volume between people living in the most disadvantaged neighbourhoods and those in other neighbourhoods. But in the end, researchers found brain shrinkage in areas of the brain associated with dementia in people in the most disadvantaged neighbourhoods, while there was no shrinkage in the other group. Researchers also found a higher rate of decline on tests that measure the risk of Alzheimer’s disease.

    “Our findings suggest that increased vigilance by healthcare providers for early signs of dementia may be particularly important in this vulnerable population,” said Kind. “Some possible causes of these brain changes may include air pollution, lack of access to healthy food and healthcare and stressful life events. Further research into possible social and biological pathways may help physicians, researchers and policymakers identify effective avenues for prevention and intervention in Alzheimer’s disease and related dementia.”

    Limitations of the study included a small number of participants from highly disadvantaged neighbourhoods and a limited geographic setting. Future studies should involve larger and more diverse groups of people over longer periods of time.

    Alpha-lipoic acid increases collagen synthesis and deposition in nondiabetic and diabetic kidneys

    University of Belgrade (Serbia), April 21, 2021

    According to news originating from Belgrade, Serbia, research stated, “Alpha-Lipoic acid (ALA) is widely used as a nutritional supplement and therapeutic agent in diabetes management. Well-established antioxidant and hypoglycemic effects of ALA were considered to be particularly important in combating diabetic complications including renal injury.”

    Our news journalists obtained a quote from the research from the University of Belgrade, “The present study evaluated the potential of ALA to affect profibrotic events in kidney that could alter its structure and functioning. ALA was administered intraperitoneally (10 mg/kg) to nondiabetic and streptozotocin-induced diabetic male Wistar rats for 4 and 8 weeks. The effects of ALA were assessed starting from structural/morphological alterations through changes that characterize profibrotic processes, to regulation of collagen gene expression in kidney. Here, we demonstrated that ALA improved systemic glucose and urea level, reduced formation of renal advanced glycation end products (AGEs), and maintained renal structural integrity in diabetic rats. However, profibrotic events provoked in diabetes were not alleviated by ALA since collagen synthesis/deposition and expression of transforming growth factor-beta 1 (TGF-beta 1) and alpha-smooth muscle actin (alpha-SMA) remained elevated in ALA-treated diabetic rats, especially after 8 weeks of diabetes onset. Moreover, 8 weeks treatment of nondiabetic rats with ALA led to the development of profibrotic features reflected in increased collagen synthesis/deposition. Besides the TGF-beta 1 downstream signaling, the additional mechanism underlying the upregulation of collagen IV in nondiabetic rats treated with ALA involves decreased DNA methylation of its promoter that could arise from increased Tet1 expression.”

    According to the news editors, the research concluded: “These findings emphasize the therapeutic caution in the use of ALA, especially in patients with renal diabetic complication.”

    Obesity, high-salt diet pose different cardiovascular risks in females, males

    Medical College of Georgia at Augusta University, April 30, 2021

    Obesity and a high-salt diet are both bad for our hearts but they are bigger, seemingly synergistic risks for females, scientists report.

    “We see younger and younger women having cardiovascular disease and the question is: What is the cause?” says Dr. Eric Belin de Chantemele, physiologist in the Vascular Biology Center and Department of Medicine at the Medical College of Georgia at Augusta University. “We think the fact that females are more salt sensitive and more sensitive to obesity are among the reasons they have lost the natural protection youth and estrogen are thought to provide.” 

    His message to women based on the sex differences they are finding: “First reduce your consumption of salt, a message the American Heart Association has been pushing for years, which should also result in a reduction in your intake of highly processed, high-calorie food and drink.”

    Belin de Chantemele, whose research team has been exploring why so many young women are now getting cardiovascular disease, is presenting their findings during the Henry Pickering Bowditch Award Lectureship at the American Physiological Society Annual Meeting at Experimental Biology 2021 this week. The award, which honors the scientist who created the first physiology lab in the country and was the American Physiological Society’s first president, recognizes original and outstanding accomplishments in the field of physiology by a young investigator. 

    The sex hormone estrogen, which has some protective powers like keeping blood vessels more flexible, is considered a natural protection for premenopausal women yet, along with soaring rates of severe obesity in young women, heart disease is now the third leading cause of death in females between the ages 20-44 — fourth for males in that age group — then moves up to second place for the next 20 years in both sexes, and is the number one killer for both men and women looking at all ages, according to the National Vital Statistics Reports. 

    While he refers to bad nutrition as the “world’s biggest killer” and obesity as a major risk factor for hypertension in both sexes, his lab has mounting evidence that obesity and high salt intake are even bigger risks for females, who have naturally higher levels of two additional hormones, leptin and aldosterone, setting the stage for the potentially deadly cardiovascular disparities. 

    Many of us likely think of leptin as the “satiety hormone” that sends our brain cues to stop eating when our stomach is full, but in obesity, the brain typically stops listening to the full message but the cardiovascular system of women starts getting unhealthy cues. 

    Belin de Chantemele has shown that in females leptin prompts the adrenal glands, which make aldosterone, to make even more of this powerful blood vessel constrictor. Like leptin, females, regardless of their weight, already have naturally higher levels of aldosterone and actually bigger adrenal glands as well. 

    A result: Obesity actually produces larger blood pressure increases in females, and studies indicate that females also are more prone to obesity associated vascular dysfunction — things like more rigid blood vessels that are not as adept as dilating. On the other hand, leptin actually increases production of the vasodilator nitric oxide — which reduces blood pressure — in the male mice, one of many cardiovascular differences they are finding between males and females. 

    Here’s another. “The major role of aldosterone is to regulate your blood volume,” Belin de Chantemele says. Increased salt intake should suppress aldosterone, and it does work that way in males, Belin de Chantemele says. But in females it appears to set them up for more trouble. 

    Aldosterone is the main mineralocorticoid, a class of hormones that helps maintain salt balance, and Belin de Chantemele and his team reported in 2019 in the journal Hypertension that the hormone progesterone, which enables pregnancy, also enables high levels of these mineralocorticoid receptors for aldosterone in the endothelial cells that line blood vessels in both female lab animals and human blood vessels. 

    When they removed the ovaries, which make estrogen and progesterone, from the female lab animals it equalized the mineralocorticoid receptor number, helping confirm that progesterone regulates the expression of the receptor in the females’ blood vessels. When they deleted either the mineralocorticoid or progesterone receptor in the females, it prevented the blood vessel dysfunction that typically follows, and just knocking out the progesterone receptor also suppressed the aldosterone receptor.

    The bottom line is that progesterone is key to the sex difference in aldosterone receptor expression on endothelial cells, which predisposes females to obesity associated, high-leptin driven endothelial dysfunction and likely high blood pressure, Belin de Chantemele says. 

    They reported a few years before in the same journal that higher leptin levels produced by more fat prompts the adrenal glands to make more aldosterone in females. “If you have higher aldosterone levels you will retain sodium and your blood volume will be higher,” he says. 

    They’ve also reported, as have others, that females are more salt sensitive than males. High sodium intake is known to raise blood pressure, by increasing fluid retention, and both pre- and postmenopausal females are more salt sensitive than males, Black females even more so, he says. 

    They’ve shown, for example, that in just seven days on a high-salt diet, the ability of female mice to relax blood vessels decreased as blood pressure increased. Treatment with the aldosterone agonist eplerenone helped correct both. 

    Because females already make more aldosterone, and the normal response of the body when you eat a lot of salt is to make even more aldosterone to help eliminate some of it, his team now proposes that females appear to have an impaired ability to reduce both the levels of the enzyme that makes aldosterone and the hormone itself, which makes them more salt sensitive. 

    One thing that means is that salt raises females’ blood pressure without them actually retaining more salt than the males. It also means that they think that blood vessels are more important in blood pressure regulation in females than males, which means they may need different treatment than males. To further compound the scenario, high salt increases the adrenal leptin receptor in the females, providing more points of action for leptin, which probably helps explain why aldosterone levels don’t decrease in females like they do in males. 

    A new $2.6 million grant (1R01HL155265-01) from the National Heart, Lung and Blood Institute is enabling them to further investigate, in both lab animals and human tissue, the female’s unique responses to a high-salt diet, include the specific contributions of the failure of aldosterone levels to drop, along with the increased expression of aldosterone and leptin receptors. 

    While trends in being overweight in about the last 50 years have held pretty steady for men and women, with decreases for men in the last handful of years, rates of severe obesity have been climbing, with women far outpacing men. 

    “We want to continue to put the puzzle together with the goal of helping restore protection from cardiovascular disease to young women, when a healthy diet and increased physical activity do not,” Belin de Chantemele says. 

    His research team includes Galina Antonova, research assistant; Dr. Reem Atawia, postdoctoral fellow; Simone Kennard, research associate; Taylor Kress and Candee Barris, graduate students; Vinay Mehta, undergraduate student at AU, Laszlo Kovacs, assistant research scientist; and Dr. Jessica Faulkner, postdoctoral fellow.

    Just 10 minutes of meditation helps anxious people have better focus

    University of Waterloo (Canada) May 1, 2021 

    Just 10 minutes of daily mindful meditation can help prevent your mind from wandering and is particularly effective if you tend to have repetitive, anxious thoughts, according to a study from the University of Waterloo.

    The study, which assessed the impact of meditation with 82 participants who experience anxiety, found that developing an awareness of the present moment reduced incidents of repetitive, off-task thinking, a hallmark of anxiety.

    “Our results indicate that mindfulness training may have protective effects on mind wandering for anxious individuals,” said Mengran Xu, a researcher and PhD candidate at Waterloo. “We also found that meditation practice appears to help anxious people to shift their attention from their own internal worries to the present-moment external world, which enables better focus on a task at hand.”

    The term mindfulness is commonly defined as paying attention on purpose, in the present moment, and without judgement.

    As part of the study, participants were asked to perform a task on a computer while experiencing interruptions to gauge their ability to stay focused on the task. Researchers then put the participants into two groups at random, with the control group given an audio story to listen to and the other group asked to engage in a short meditation exercise prior to being reassessed.

    “Mind wandering accounts for nearly half of any person’s daily stream of consciousness,” said Xu. “For people with anxiety, repetitive off-task thoughts can negatively affect their ability to learn, to complete tasks, or even function safely.

    “It would be interesting to see what the impacts would be if mindful meditation was practiced by anxious populations more widely.”

    The study, co-authored by Waterloo psychology professors Christine Purdon and Daniel Smilek and Harvard University’s Paul Seli, was published in Consciousness and Cognition.

    Researchers find breastfeeding linked to higher neurocognitive testing scores

    University of Rochester Medical Center, April 27, 2021

    New research finds that children who were breastfed scored higher on neurocognitive tests. Researchers in the Del Monte Institute for Neuroscience at the University of Rochester Medical Center (URMC) analyzed thousands of cognitive tests taken by nine and ten-year-olds whose mothers reported they were breastfed, and compared those results to scores of children who were not.

    “Our findings suggest that any amount of breastfeeding has a positive cognitive impact, even after just a few months.” Daniel Adan Lopez, Ph.D. candidate in the Epidemiology program who is first author on the study recently published in the journal Frontiers in Public Health. “That’s what’s exciting about these results. Hopefully from a policy standpoint, this can help improve the motivation to breastfeed.”

    Hayley Martin, Ph.D., a fourth year medical student in the Medical Scientist Training Program and co-author of the study, focuses her research on breastfeeding. “There’s already established research showing the numerous benefits breastfeeding has for both mother and child. This study’s findings are important for families particularly before and soon after birth when breastfeeding decisions are made. It may encourage breastfeeding goals of one year or more. It also highlights the critical importance of continued work to provide equity focused access to breastfeeding support, prenatal education, and practices to eliminate structural barriers to breastfeeding.”

    Researchers reviewed the test results of more than 9,000 nine and ten-year-old participants in the Adolescent Brain Cognitive Development (ABCD) study. Variations were found in the cumulative cognitive test scores of breastfed and non-breastfed children. There was also evidence that the longer a child was breastfed, the higher they scored. 

    “The strongest association was in children who were breastfed more than 12 months,” said Lopez. “The scores of children breastfed until they were seven to 12 months were slightly less, and then the one to six month-old scores dips a little more. But all scores were higher when compared to children who didn’t breastfeed at all.” Previous studies found breastfeeding does not impact executive function or memory, findings in this study made similar findings.

    “This supports the foundation of work already being done around lactation and breastfeeding and its impact on a child’s health,” said Ed Freedman, Ph.D., the principal investigator of the ABCD study in Rochester and lead author of the study. “These are findings that would have not been possible without the ABCD Study and the expansive data set it provides.”

The Gary Null Show - 05.03.21

The Gary Null Show - 05.03.21

May 3, 2021

The day the world ended began like any other day. People woke up, had their coffee, checked their social media, kissed their loved ones, went to work.

Nobody knew it was coming. The news reporters and pundits hadn’t been informing them that the US and its allies had been simultaneously ramping up aggressions against two nuclear-armed nations in a way that could easily lead to something going catastrophically wrong, or explained to them what this could mean for them and their loved ones. The mass media had never let the truth interfere with the military agendas of their government before, and, as it turns out, they never would.

Nobody knew it was coming, so nobody opposed the dangerous acts of brinkmanship that led up to it. Nobody resisted as the Democrats manufactured consent for escalation after escalation against Russia. Nobody resisted as the Republicans manufactured consent for escalation after escalation against China. Nobody objected as war ships were moved, as troops were deployed, as Nuclear Posture Reviews became more and more hawkish and aggressive, as new armageddon weapons were manufactured and fielded, as proxy conflicts were backed, as war planes encroached upon sovereign airspace, as missiles were readied for swift deployment.

So it simply did not feature in anyone’s mind that this could be the day they and their loved ones die in a nuclear holocaust.

They just went about their day, like it was any other day. Working, texting, thinking pointless thoughts, arguing about nonsense with strangers on the internet.

Then it happened. A nuclear weapon was deployed by one side, setting off a chain reaction that had been set in place ready to be triggered long ago, from which there was no coming back.

And the funny thing is, it was an accident. Just a stupid, innocent mistake. One of the thousands of people responsible for the operation of those horrific weapons got a little careless with their part in the day-to-day management of the imperfect technology used in an international nuclear standoff that had become increasingly tense and confusing amid rapidly rising cold war chaos.

That’s all it took. Nothing grand or dramatic. Just a bad decision, made at the wrong time.

One minute it seemed fine. The next minute it was the end. The end of everything.

Nothing rearranges your mental priorities like looking outside and seeing a mushroom cloud growing on the horizon. Suddenly your particular political ideology doesn’t feel so significant anymore. Your personal beef with your coworker loses its importance. That heated argument you were having online slips forgotten from your mind. In fact, nearly everything you’d spent your mental mental energy on that day up until that point feels like a ridiculous, pathetic joke.

There was fear of course. Panic of course. People ran. People hid. But the realization spread very quickly that there was no escaping this one. That this was the end.

And, in that brief moment of helpless surrender to the inevitable, humanity was the most awake it’s ever been. The most tuned in. The most compassionate. The most loving. The most united. If there’d been anyone outside of it to witness it, the beauty of our species in that moment would have taken their breath away.

The earth shook. The flames spread. Black carbon was hurled into the stratosphere for decades. All the earth’s creatures perished in the darkness and radiation.

And then it was all still. Still and silent.

It was a mistake. A stupid, silly mistake, just like all the other stupid silly mistakes we’ve made since the moment we first stood upright. It’s just that this mistake was our last one.

The only difference between our final mistake and all the innumerable others which preceded it was that there was nobody left to fix this one. To try and course correct. To say “Ah, I see where you went wrong there, let’s make some adjustments and try a different approach.”

No one left to recognize the mistake, to grow as a result of that recognition, and to rise above it. No one left to realize how staggeringly insane it was to flirt with the end of the world for the sake of power, how arrogant it was to think that we could remain in perfect control of all those weapons for decades on end without something going wrong amid our reckless games of nuclear chicken.

No one left to realize there’s no good reason we need to live in a world where governments brandish such weapons at each other just because a few sociopaths decided that US unipolar domination needs to be preserved at all cost. No one left to realize we could all just lay down our weapons and get along with each other, and begin collaborating with each other toward a peaceful and harmonious world.

It would be so, so wonderful if that had happened. But it didn’t. And now it’s all gone.

And it’s too late to fix our mistake.
