It is Time to Dismantle the World Health Organization

Progressive Radio Network, April 19, 2021

The ultimate international authority for infectious diseases is the World Health Organization (WHO). Due to its widespread acceptance by the world's national governments, it has been extremely successful in assuming the helm to monitor regional and global infectious diseases and dictate medical intervention policies to international health agencies. The organization has become the final word to rule whether the spread of a serious pathogen is a pandemic or not. For the majority of the medical community, the media and the average person, the WHO is the front line command post for medical prevention (i.e., vaccination) and treatment.  Consequently its rulings are often regarded as the gold standard.  On matters of global health, the WHO holds dominance. 

For approximately a year the WHO has propagated the belief that the first line of defense for curtailing the COVID-19 pandemic is self-isolation, distancing, masks and, ultimately, vaccination. Although it approved Ivermectin as a cost-effective treatment against SARS-CoV-2 infections, it disapproved hydroxychloroquine in favor of Gilead Bioscience’s and the National Institute of Allergy and Infectious Disease’s (NIAID) Anthony Fauci’s novel and costly drug Remdesivir.  Much of it’s funding efforts have been reserved for mass-vaccination with the new generation of experimental vaccines. Throughout these efforts, the WHO has allied itself with the US's and UK’s national health systems, and the Bill and Melinda Gates Foundation and his Global Alliance for Vaccines and Immunization (GAVI) initiative. 

Most people wrongly assume the WHO acts independently from private commercial and national government interests for the welfare of the world's population. The legitimacy of the WHO as a gold standard of health is dubious. The organization has frequently been accused of conflicts of interests with private pharmaceutical companies and mega-philanthropic organizations such as the Gates’ Foundation, as well as being riddled with political alliances, ideologies, and profiteering motives. Despite it’s mega-pharmaceutical interests and consultants representing private vaccine interests, in the past the WHO has had the audacity to ridicule the pharmaceutical industry of corruption.

“Corruption in the pharmaceutical sector occurs throughout all stages of the medicine chain, from research and development to dispensing and promotion…. A lack of transparency and accountability within the medicines chain can also contribute to unethical practices and corruption.”

These are similar charges that have been leveled against the WHO. An article in the National Review called the WHO "scandal plagued" with "wasteful spending, utter disregard for transparency, pervasive incompetence, and failure to adhere to even basic democratic standards." In his book, Immunization: How Vaccines Became Controversial, University of Amsterdam professor emeritus Dr. Stuart Blume raises the serious problem of the WHO’s most influential advisors on emergency health conditions, such as the current Covid-19 pandemic and earlier the 2009 H1N1 swine flu scare that never was, serve as consultants for the vaccine industry. During times of global emergencies and crises, the WHO confers with a separate group of advisors outside its formal sitting Strategic Advisory Group of Experts or SAGE; the names of this group’s members are not made public. 

We would add that the WHO’s level of incompetence has resulted in serious misinformation about pandemics, medical risks of vaccines and other health-threatening chemicals.  For example, during the early stage of the COVID-19 outbreak in Wuhan, the organization reported it could not find any evidence of human transmission. However, the WHO has repeatedly kowtowed to China’s demands and unscrupulously accepts whatever statistics and statements the Chinese Communist Party (CCP) provides. Responding to a petition signed by over 700,000 signatories demanding the resignation of the current WHO Director General Tedros Adhanom, Japan’s Deputy Prime Minister Taro Aso told the Japanese parliament that the organization “should be renamed the Chinese Health Organization” for favoring China’s policy to stall and obstruct international investigations and for lauding unsubstantiated praise on the country’s transparency and handling of the pandemic. Back on December 31, 2019, Taiwan – which has been barred from WHO membership due to China’s political maneuvering – had been warning of a possible human-to-human transmission contrary to the wet-market narrative, but this was largely ignored in order to avoid upsetting the CCP.

The UK’s Sunday Times reported that Chinese scientists were forced to destroy their proof of the virus shortly after its discovery. In the province of Hubei, authorities ordered the cessation of further testing and the destruction of existing samples. Other researchers who made efforts to warn the public were punished.  Writing for The Hill, University of Texas at San Antonio professor Bradley Thayer wrote, “Tedros apparently turned a blind eye to what happened in Wuhan and the rest of China and… has helped play down the severity, prevalence and scope of the Covid-19 outbreak.” Thayer concludes, “Tedros is not fit to lead the WHO.” He has no formal medical training as a physician or any international management experience in global health. Many others have voiced similar criticisms pointing out Tedro’s unsuitable background.  Moreover, the Director General’s conflicts of interest with China abound. Immediately before and after his tenure as the Health Minister for Ethiopia’s ruling Communist party, the Tigray People’s Liberation Front, China had donated an estimated $60 million to the terrorist government and its social programs. Now heading the WHO, Tedros appears to continue lobbying on China’s behalf. In 2017, the Washington Post noted the fundamental problem: 

“[China] worked tirelessly behind the scenes to help Tedros defeat the United Kingdom candidate for the WHO job, David Nabarro. Tedros’s victory was also a victory for Beijing, whose leader Xi Jinping has made public his goal of flexing China’s muscle in the world.”

Upon assuming his new position at the WHO, Tedros had left Ethiopia’s healthcare system in ruin.  As one young healthcare worker reported, there was no “bare necessities of a health care office…. Sterile gloves, paper exam gowns and covers, cotton swabs, gauze, tongue depressors, alcohol prep pads, chemical test strips, suturing equipment, syringes, stethoscopes… were non-existent. This is a fact in most health care centers in Ethiopia.” 

During the more recent re-investigation of SARS-CoV-2 origins, the Chinese authorities refused to provide raw case data and created repressive conditions to curtail reliable analysis and disclosure. The WHO’s final report concluded that the virus had an animal origin and did not escape Wuhan’s high security pathogen laboratory. But there are viable reasons to discredit the report as untrustworthy at best and perhaps intentionally deceptive. 

First, the entire agenda of the investigation was staged theater rather than a deep investigation to uncover empirical evidence. The team simply inspected seafood and open-air markets. Consequently, the WHO team returned empty handed and without laboratory records for a proper forensic examination. To call the entire WHO effort gross incompetence would be an understatement. Based upon all the evidence that has emerged, a large number of professional medical voices are calling the entire investigation a farce.

Most problematic is the appointment of Peter Daszak on the WHO’s group to carry out the investigation. Daszak, the founding president of the shadowy non-profit organization EcoHealth Alliance, has headed many hunting adventures worldwide to identify the emergence of potential pathogens that could become pandemics. With the intention to divert attention away from an escaped laboratory virus, Daszak stated on a Going Viral podcast there was no evidential reason to visit and inspect the Wuhan laboratory. According to Independent Science News, despite Daszak’s denial of a lab origin, “EcoHealth Alliance funded bat coronavirus research, including virus collection, at the Wuhan Institute of Virology and thus could themselves be directly implicated in the outbreak.” The research at the Wuhan lab included ‘gain of function” efforts on coronaviruses, and received funds directly approved by Anthony Fauci. Newsweek reports the NIH had given a total of $7.4 million to the Chinese lab for the research. The organization has received over $100 million from a variety of sources, including the Department of Defense, Homeland Security, the NIH and undisclosed amounts from the Chinese government. Daszak himself has authored 25 studies funded by the Chinese Academy of Medical Sciences, think tanks, universities, military institutions, and ministries directly connected with the Chinese Communist Party. 

Given the halls of power within the WHO, we are outlining some of the more salient reasons why the organization's declarations about infectious diseases, pandemics and vaccination should not be trusted. 

Vaccine Promotional Misconduct

For many years the WHO's recommendations for certain vaccines were kept secret. Writing in a 2006 issue of the Journal of American Physicians and Surgeons, Dr. Marc Girard uncovered "scientific incompetence, misconduct or even criminal malfeasance" over the intentional inflation of vaccines' benefits while undermining toxicity and adverse effects. Dr. Girard testified as a medical expert for a French court in a criminal trial against the WHO after French health officials obliged the organization to launch its universal Hepatitis B vaccine campaign. The campaign resulted in the deaths of French children. Girard gained access to confidential WHO documents. He noted that the WHO's "French figures about chronic liver diseases were simply extrapolated from the U.S. reports." He further accused the WHO serving "merely as a screen for commercial promotion, in particular via the Viral Hepatitis Prevention Board (VHPB), which was created, sponsored, and infiltrated by the manufacturers."

Now during the Covid-19 pandemic, as early as last July, the WHO approved of China’s first vaccine for emergency use, long before it had undergone proper clinical trials and much earlier than Moderna’s and Pfizer’s mRNA vaccines’ approval.

Orchestration of Pandemic Panics

Before the current COVID-19 pandemic, there was the H1N1 swine flu scare in 2009. However, at the very start the WHO's fear mongering of a global contagion that could exceed the death counts of the 1918 Spanish flu pandemic was solely based on false rhetoric rather than empirical evidence.  The fabrications are believed to have originated from the WHO's senior consultant on viral outbreaks who happens to carry the reputation of being one of the world's leading pandemic alarmists: Dr. Albert Osterhaus, nicknamed "Dr. Flu." At the time, Osterhaus was head of the Department of Virology at Erasmus University in the Netherlands. When the swine flu scare appeared, he was also the president of the European Scientific Working Group on Influenza (ESWI), an organization funded by the major vaccine manufacturers including Baxter, MedImmune, Glaxo, Sanofi Pasteur and others. It was also Osterhaus who transformed an otherwise potentially bad flu season into a global pandemic. The WHO has been criticized harshly in the media for changing the definition of a "pandemic" and in doing so has been charged with benefitting the pharmaceutical industry. The British Medical Journal reported that the WHO failed to report conflicts of interest in its H1N1 advisory group. The journal's Editor-in-Chief Fiona Godlee wrote, "WHO must act now to restore its credibility, and Europe should legislate." The former head of the prestigious Cochrane Database Collaboration’s vaccine studies, Dr. Tom Jefferson, told a Der Spiegel interviewer, “the WHO and public health officials, virologists and the pharmaceutical companies... built this machine around the impending [H1N1] pandemic. And there’s a lot of money involved, and influence and careers, and entire institutions.”

When the 2009 H1N1 influenza strain appeared, the WHO rushed forward to mangle its earlier criteria that would realistically define a pandemic. The organization intentionally removed reference to a pathogen’s “severity” as a necessary requirement. “Don’t you think there’s something noteworthy,” Dr. Jefferson continues, “about the fact that the WHO has changed its definition of a pandemic?.... that’s how swine flu has been categorized as a pandemic.” Moreover, the WHO’s decision to label the outbreak as a pandemic was not based upon its own permanent vaccine experts but on the recommendations of a non-disclosed group of outside consultants. 

According to a financial forecast published by JP Morgan, the collaboration between the WHO and Osterhaus's ESWI to orchestrate the pandemic would have profited the pharmaceutical industry up to $10 billion. Der Spiegel reported:

“The WHO and those in charge of public health, the virologists and the pharmaceutical laboratories....  created a whole system around the imminence of a pandemic. There is a lot of money at stake, as well as networks of influence, careers and whole institutions! And the minute one of the flu viruses mutates we’d see the whole machine roll into action.”

In 2010, the EU’s Parliamentary Assembly of the Council of Europe launched an investigation into the evidence that the WHO had created “a fake pandemic” in order to financially benefit the pharmaceutical giants’ vaccine market and to strengthen the influence private drug interests have over the health organization. The Assembly’s chairperson Dr. Wolfgang Wodarg charged the WHO’s fake pandemic as “one of the greatest medical scandals of the century that resulted in “millions being needlessly vaccinated.”

Epidemic of Conflict of Interests

According to former World Bank geopolitical analyst Peter Koenig, about half of the WHO's budget is derived from private sources -- primarily pharmaceutical companies but also other corporate sectors including the telecommunication and agro-chemical industries. It also receives large donations from large philanthropic organizations such as the Bill and Melinda Gates Foundation and GAVI. Eleven years ago, Gates had committed $10 billion to the WHO; after the US, his Foundation is its second largest donor providing 10 percent of its funding.  His financial commitment aligned with his global ambition to “make this the decade of vaccines.” Koenig also believes that Tedros’s appointment was due to Gates' influence. This may carry some truth because Tedros is a former Chair of GAVI’s Vaccine Alliance. Barbara Loe Fisher at the National Vaccine Information Center estimates that "only about 10 percent of total funding provided by GAVI ($862M) was used to strengthen health systems in developing countries, such as improving sanitation and nutrition, while nearly 80 percent was used to purchase, deliver and promote vaccines." 

There is also the deep personal and financial relationship between Gates and the Chinese Communist government that demands further investigation. Gates is a member of the Chinese Academy of Science. For the moment, the WHO has been advising against Covid-19 vaccine passports as a mandate to travel. Nevertheless, China has already launched encrypted digital certificates as proof of vaccination. Given Gates’ close relationship with Chinese officials, perhaps he is awaiting on China to establish a precedent for other nations to agree on a global mandate that will eventually be propagated by the Gate’s network and the World Economic Forum and its Great Reset.  During a 2020 TED talk, Gates had already revealed that digital vaccine passports may be necessary; that part of his speech was edited from the original video, however, Robert Kennedy Jr. tracked down the original footage.  Gates has also 1) commissioned MIT to develop injectable a quantum dot dye system for children, 2) funded MicroChips, a company developing implantable chip-based devices, and 3) purchased 3.7 million shares in Serco who is developing tracing technology to track pandemic infections and vaccine compliance.

Finally, Gates shares the Chinese Communist Party’s interests in collecting and ‘mining” citizens’ DNA. A 60 Minutes expose presented the covert activities of BGI Genomics, a CCP-linked firm that has exported Covid-19 tests to “collect, store and exploit biometric information” on American citizens. Independent investigations reveal that the Gates Foundation has collaborated with BGI and it was through Gates’ influence over Obama that the Chinese company entered the US market. 

BGI’s RT-PCR kit was promoted by the WHO back in May 2020 for first line emergency diagnostic use. The rationale was that the test was highly sensitive, specific and user-friendly. Subsequently the EU, FDA, and the Australian, Canadian and Japanese health ministries rapidly purchased and deployed it. On its website, the Gates Foundation acknowledges its role in having the PCR tests supplied to the WHO.

“Nine Chinese PCR tests were approved by WHO during 2020 under its Emergency Use Listing (EUL) mechanism, with one of the foundation’s partners supplying tests to WHO”

Three months later, Sweden filed complaints after reports of a high percentage of false positives from the Chinese tests. 

There is in our opinion little doubt that the WHO is another one of Gates' bought off entities for furthering his personal agenda to promote vaccines, genetically modified seeds and chemical agriculture in the developing world. 

Vaccine Adverse Effects Monitoring System Needs Overhaul

The WHO's Global Advisory Committee on Vaccine Safety is the group responsible for administering vaccine programs in poorer, developing countries. It is also responsible for gathering data on incidents of vaccine injuries. Any deaths following vaccination campaigns are ignored and ruled as coincidental. This policy is based on the erroneous assumption that if no one died during a vaccine's clinical trials, then the vaccine should be regarded as automatically safe and unrelated to any deaths that might occur later. Consequently, the WHO's monitoring system is seriously flawed and requires a major overhaul. 

One of the more controversial incidences was the WHO's collaboration with the Bill Gates’ GAVI campaign to launch the Pentavalent vaccine (diphtheria, pertussis, tetanus, HIP and Hepatitis B) in Africa and later in South and Southeast Asia. In India, health officials recorded upwards to 8,190 additional infant deaths annually following Pentavalent campaign.  The WHO’s response was to reclassify its adverse event reporting system to disregard "infant" deaths altogether. Dr. Jacob Puliyel, a member of the Indian government's National Technical Advisory Group on Immunization concluded, 

“deaths and other serious adverse events following vaccination in the third world, that use WHO-AEFI classification are not recorded in any database for pharmaco-vigilance. It is as if the deaths of children in low (and middle) income countries are of no consequence.”

WHO's Double Standards of Vaccine Safety

A more recent scandal erupted during the WHO's Global Vaccine Safety Summit convened in December 2019.  Days before the summit, one of the WHO's medical directors for vaccination, Dr. Soumya Swaminathan, appeared in a public advertisement touting the unquestionable safety of vaccines and ridiculing parents who speak out against vaccination. She assured viewers that the WHO was in control of matters and monitored any potential adverse risks carefully. However, during the Summit, the same Dr. Swaminathan acknowledged vaccine health risks and stated, "We really don't have very good safety monitoring systems." Another Summit participant, Dr. Heidi Larson stated,

"We have a very wobbly ‘health professional frontline’ that is starting to question vaccines and the safety of vaccines. When the frontline professionals are starting to question or they don’t feel like they have enough confidence about the safety to stand up to the person asking the questions. I mean most medical school curriculums, even nursing curriculums, I mean in medical school you are lucky if you have half a day on vaccines.”

And more noteworthy were the statements by Dr. Martin Howell Friede, Coordinator of the WHO's Initiative for Vaccine Research, 

"... I give courses every year on how do you develop vaccines, how do you make vaccines. And the first lesson is while you’re making your vaccine if you can avoid using an adjuvant please do so. Lesson two is if you’re going to use an adjuvant use one that has a history of safety. And lesson three is if you’re not going to do that, think very carefully."

In other words, what the WHO presents to the public contradicts what is discussed behind closed doors, another example of the veil of secrecy the organization operates within. 

Now we are witnessing more countries halting further administration of AstraZeneca’s Covid vaccine, a vaccine Trump had committed $1.2 billion towards its development. Subsequently the CDC paused Johnson & Johnson’s similar engineered adenovirus vaccine in order to investigate its association with an otherwise rare condition of fatal blood clotting. The WHO on the other hand has ignored these nations’ ethical responsibility to adhere to the precautionary principle. Its own review claimed there were no blood clot links to AstraZeneca’s vaccine; later the WHO changed its tune to “plausible” after EU regulators found a causal link and the New England Journal of Medicine published two studies providing specific details confirming these adverse reactions.  Although acknowledging these risks, the WHO has continued to recommend that mass vaccination proceed as if there were no red alarms.  

WHO's Depopulation Efforts with Vaccines

Without doubt, the most nefarious activity conducted by the WHO is its alleged support and distribution of vaccines to poorer developing countries that may have been intentionally designed to decrease population rates.  Back in 1989, the WHO sponsored a symposium at its Geneva headquarters on "Antifertility Vaccines and Contraceptive Vaccines." The symposium presented proposals for vaccines that were later discovered to have been laced with the sterilizing hormones HCG and estradiol; the former prevents pregnancy and triggers spontaneous abortions and miscarriages, and the latter can turn men infertile.  

In 2015, the Kenyan Conference of Catholic Bishops reported its discovery of a polio vaccine laced with estradiol that was manufactured in India and distributed by the WHO. A year earlier, Dr. Wahome Ngare from the Kenyan Catholic Doctors Association uncovered a tetanus vaccine specifically being administered to women, also distributed by the WHO, that contained the HCG hormone. All of the polio vaccine samples tested contained HCG, estrogen-related compounds, follicle stimulating and luteinizing hormones, which will damage sperm formation in the testes. Even more disturbing, this vaccine was going to be administered to children under five years of age. 

However, this is not the first time the WHO appears to have made efforts to use vaccination campaigns for depopulation.  A decade earlier, in 2004, the WHO, UNICIF and CDC launched a vaccination campaign to immunize 74 million African children during a polio outbreak. The initiative encountered a serious obstacle. In Nigeria, laboratory tests on the WHO's vaccine samples resulted in the presence of estrogen and other female hormones. And in the mid-1990s, a tetanus vaccine being administered to Nicaraguan and Filipino girls and women in their child-bearing years was discovered to contain HCG, which accounted for a large number of spontaneous abortions that were reported by Catholic health workers. 

Illegal Vaccine Experiments

In 2014, The Economic Times of India published a report that provided details of a joint venture between the WHO and the Gates Foundation to test an experimental HPV vaccine on approximately 16,000 tribal girls between the ages of 9 and 15 unwittingly. The experiment was conducted in 2008, and the vaccine is now what we commonly know as Gardasil. Many of the girls, the report states, became ill and some died. 

The following year the WHO and Gates Foundation conducted a similar experiment on 14,000 girls with the HPV vaccine Cervarix. Again "scores of teenage girls were hospitalized."  Investigations led by Indian health officials uncovered gross violations in India's laws regarding medical safety. In numerous cases there was no consent and the children had no idea what they were being vaccinated for. The Indian Supreme Court has taken up a case against the duo for criminal charges. 

There are many other questionable activities that the WHO has been involved with over the years. However, the above provide sufficient evidence to argue the case that, at least within the upper echelons of the WHO, global health does not stand in high priority.  The organization employs over 7,000 people around the world and most of these have deep concern for improving the lives of populations in poor and developing nations. On the other hand, the WHO's leaders are there largely because the powers of Washington, London and the pharmaceutical industry benefit by the organization advancing its agendas. 

Of course, the WHO is not the only health entity with a legacy of corruption.  Corruption appears to be systemic throughout global health and national health agencies.  This topic was featured last year in the prestigious medical journal The Lancet. Author Dr. Patricia Garcia writes, 

"Corruption is embedded in health systems. Throughout my life—as a researcher, public health worker, and a Minister of Health—I have been able to see entrenched dishonesty and fraud. But despite being one of the most important barriers to implementing universal health coverage around the world, corruption is rarely openly discussed."

Bear in mind, the WHO, along with Bill Gates and his Foundation, and Anthony Fauci at the National Institutes for Allergy and Infectious Disease, are leading the efforts to get the COVID-19 vaccine administered as quickly as possible. Already the Gates Foundation has given $1.75 billion for developing and distributing these vaccines. Do you believe we can trust their judgment and the intense public relations effort that will immediately follow after such a vaccine reaches the market?

Mushrooms boost immunity, suggests research

University of Florida Institute of Food and Agricultural Sciences, April 13. 2021

Could a mushroom a day help keep the doctor away?

A new University of Florida study shows increased immunity in people who ate a cooked shiitake mushroom every day for four weeks.

Of the thousands of mushroom species globally, about 20 are used for culinary purposes. Shiitake mushrooms are native to Asia and are cultivated for their culinary and medicinal value.

A study led by UF Food Science and Human Nutrition Professor Sue Percival, 52 healthy adults, age 21 to 41, came to the Gainesville campus, where researchers gave them a four-week supply of dry shiitake mushrooms. Participants took the mushrooms home, cleaned and cooked them. Then they ate one, 4-ounce serving of mushrooms each day during the experiment.

Through blood tests before and after the experiment, researchers saw better-functioning gamma delta T-cells and reductions in inflammatory proteins.

"If you eat a shiitake mushroom every day, you could see changes in their immune system that are beneficial," said Percival, an Institute of Food and Agricultural Sciences faculty member. "We're enhancing the immune system, but we're also reducing the inflammation that the immune system produces."

To be eligible for the study, participants could not be vegans or vegetarians. They also could not drink tea, take antioxidant supplements or probiotics before the study. They also could not consume more than 14 glasses of alcoholic beverages per week or eat more than seven servings of fruits and vegetables per day during the experiment.

Percival explained the dietary restrictions as follows: Fiber, tea and probiotics help the body's immune system, so researchers didn't want to start with people who already had a strong immune system. Additionally, that much alcohol could suppress immunity, she said.

The study was published  in the Journal of the American College of Nutrition.

Metabolic changes in fat tissue in obesity associated with adverse health effects

University of Helsinki (Finland), April 9, 2021

Researchers at the Obesity Research Unit of the University of Helsinki have found that obesity clearly reduces mitochondrial gene expression in fat tissue, or adipose tissue. Mitochondria are important cellular powerplants which process all of our energy intake. If the pathways associated with breaking down nutrients are lazy, the changes can often have health-related consequences.

A total of 49 pairs of identical twins discordant for body weight participated in the study conducted at the University of Helsinki: their body composition and metabolism were studied in detail, and biopsies from adipose and muscle tissue were collected. Multiple techniques for analysing the genome-wide gene expression, the proteome and the metabolome were used in the study. 

The study was recently published in the journal Cell Reports Medicine.

According to the findings, the pathways responsible for mitochondrial metabolism in adipose tissue were greatly reduced by obesity. Since mitochondria are key to cellular energy production, their reduced function can maintain obesity. For the first time, the study also compared the effects of obesity specifically on the mitochondria in muscle tissue in these identical twin pairs: muscle mitochondria too were found to be out of tune, but the change was less distinct than in adipose tissue. 

The study provided strong evidence of a connection between the low performance of adipose tissue mitochondria and a proinflammatory state. Furthermore, the findings indicate that metabolic changes in adipose tissue are associated with increased accumulation of fat in the liver, prediabetic disorders of glucose and insulin metabolism as well as cholesterol.

"If mitochondria, the cellular powerplants, are compared to the engine of a car, you could say that the power output decreases as weight increases. A low-powered mitochondrial engine may also generate toxic exhaust fumes, which can cause a proinflammatory state in adipose tissue and, consequently, the onset of diseases associated with obesity," says Professor Kirsi Pietiläinen from the Obesity Research Unit, University of Helsinki.

"What was surprising was that the mitochondrial pathways in muscle had no association with these adverse health effects," Pietiläinen adds.

Obesity also affected amino acid metabolism

In the study, changes in mitochondrial function were also seen in amino acid metabolism. The metabolism of branched-chain amino acids, which are essential to humans, was weakened in the mitochondria of both adipose tissue and muscle tissue.

"This finding was of particular significance because the reduced breakdown of these amino acids and the resulting heightened concentration in blood have also been directly linked with prediabetic changes and the accumulation of liver fat in prior twin studies," says Pietiläinen.

Obesity, with its numerous associated diseases, is a common phenomenon that is continuously increasing in prevalence. While lifestyle influence the onset of obesity, genes also have a significant role. 

"Identical twins have the same genes, and their weight is usually fairly similar. In fact, studying twins is the best way to investigate the interplay between genes and lifestyle. In spite of their identical genome, the genes and even mitochondria of twins can function on different activity levels. We utilised this characteristic in our study when looking into the effects of weight on tissue function," Pietiläinen says.

Research suggests selenium supplementation may extend lifespan

Orentreich Foundation for the Advancement of Science (Cold Spring), April 12, 2021

Adding the nutrient selenium to diets protects against obesity and provides metabolic benefits to mice, according to a study published in eLife.

The results could lead to interventions that reproduce many of the anti-aging effects associated with dietary restriction while also allowing people to eat as normal.

Several types of diet have been shown to increase healthspan - that is, the period of healthy lifespan. One of the proven methods of increasing healthspan in many organisms, including non-human mammals, is to restrict dietary intake of an amino acid called methionine.

Recent studies have suggested that the effects of methionine restriction on healthspan are likely to be conserved in humans. Although it might be feasible for some people to practice methionine restriction, for example, by adhering to a vegan diet, such a diet might not be practical or desirable for everyone. In the current study, a research team from the Orentreich Foundation for the Advancement of Science(OFAS), Cold Spring, New York, US, aimed to develop an intervention that produces the same effects as methionine restriction, while also allowing an individual to eat a normal, unrestricted diet.

An important clue for developing such a treatment is that methionine restriction causes a decrease in the amounts of an energy-regulating hormone called IGF-1. If a treatment could be found that causes a similar decrease in IGF-1, this might also have beneficial effects on healthspan. Previous research has shown that selenium supplementation reduces the levels of circulating IGF-1 in rats, suggesting that this could be an ideal candidate.

The team first studied whether selenium supplementation offered the same protection against obesity as methionine restriction. They fed young male and older female mice one of three high-fat diets: a control diet containing typical amounts of methionine, a methionine-restricted diet, and a diet containing typical amounts of methionine as well as a source of selenium. For both male and female mice of any age, the authors found that selenium supplementation completely protected against the dramatic weight gain and fat accumulation seen in mice fed the control diet, and to the same extent as restricting methionine.

Next, they explored the effects of the three diets on physiological changes normally associated with methionine restriction. To do this, they measured the amounts of four metabolic markers in blood samples from the previously treated mice. As hoped, they found dramatically reduced levels of IGF-1 in both male and female mice. They also saw reductions in the levels of the hormone leptin, which controls food intake and energy expenditure. Their results indicate that selenium supplementation produces most, if not all, of the hallmarks of methionine restriction, which suggests that this intervention may have a similar positive effect on healthspan.

To gain insight into the beneficial effects of selenium supplementation, the researchers used a different organism - yeast. The two most widely used measurements of healthspan in yeast are chronological lifespan, which tells us how long dormant yeast remain viable, and replicative lifespan, which measures the number of times a yeast cell can produce new offspring. The team previously showed that methionine restriction increases the chronological lifespan of yeast, so they tested whether selenium supplementation might do the same. As it turned out, yeast grown under selenium-supplemented conditions had a 62% longer chronological lifespan (from 13 days to 21 days) and a replicative lifespan extended by nine generations as compared with controls. This demonstrates that supplementing yeast with selenium produces benefits to healthspan detectable by multiple tests of cell aging.

“One of the major goals of aging research is to identify simple interventions that promote human healthspan,” notes senior author Jay Johnson, Senior Scientist at OFAS. “Here we present evidence that short-term administration of either organic or inorganic sources of selenium provides multiple health benefits to mice, the most notable of which being the prevention of diet-induced obesity. In the long term, we expect that supplementation with these compounds will also prevent age-related disease and extend the overall survival of mice. It is our hope that many of the benefits observed for mice will also hold true for humans.”

Adherence to Mediterranean Diet Is Associated With Lung Function in Older Adults

Kapodistrian University (Greece), April 3, 2021

Objective: The aim of this work was to examine the association between adherence to a Mediterranean diet (MD) and lung function in older adults.

Design: This was an observational and cross-sectional study.

Setting: This research was conducted among community-dwelling older adults from the 2014 Health and Retirement Study (HRS).

Subjects: Subjects were 2108 adults aged 50 years or older, 1234 (58.5%) of whom were female.

Measures: Dietary intakes from respondents of the Health and Retirement Study (HRS) were used for the current analysis. Adherence to MD was evaluated using the MedDietScore, while lung function was evaluated through peak expiratory flow rate (PEF; l/min). Multiple linear regression and logistic regression were performed, adjusted for potential confounders, to examine the relation between adherence to MD and lung function.

Results: Mean MedDietScore was 28.0 (± 5.0), indicating a moderate adherence to MD. Multiple linear regression showed a significant association between the MedDietScore and lung function (β = 0.072, 95% confidence interval [CI]: 0.039–0.104) after adjusting for age, gender, body mass index, race, comorbidities, education, height, grip strength, smoking history, physical activity, and daily caloric intake. Specific food groups such as grains, dairy products, and fish consumption were also associated with PEF rate (p < 0.05). Logistic regression confirmed these findings, and high adherence to MD was associated with reduced risk of having PEF rate < 80% of its peak predictive value (odds ratio: 0.65, 95% CI: 0.48–0.89).

Conclusions: The results of this study indicate that adherence to MD is an independent predictor of lung function in older adults, and dietary interventions could be a possible preventive measure in adults with a high risk of developing lung function decline.

Leaking calcium in neurons an early sign of Alzheimer's pathology

Yale University, April 9, 2021

Alzheimer's disease is known for its slow attack on neurons crucial to memory and cognition. But why are these particular neurons in aging brains so susceptible to the disease's ravages, while others remain resilient?

A new study led by researchers at the Yale School of Medicine has found that susceptible neurons in the prefrontal cortex develop a "leak" in calcium storage with advancing age, they report April 8 in the journal Alzheimer's & Dementia, The Journal of the Alzheimer's Association. This disruption of calcium storage in turns leads to accumulation of phosphorylated, or modified, tau proteins which cause the neurofibrillary tangles in the brain that are a hallmark of Alzheimer's.

These changes occur slowly, building over many years, and can be seen within neurons in the brains of very old monkeys, the researchers report.

"Altered calcium signaling with advancing age is linked to early-stage tau pathology in the neurons that subserve higher cognition," said corresponding author Amy Arnsten, the Albert E. Kent Professor of Neuroscience and professor of psychology and member of the Kavli Institute of Neuroscience at Yale University.

These vulnerable neurons face another problem. As they age, they tend to lose a key regulator of calcium signaling, a protein called calbindin, which protects neurons from calcium overload, and is abundant in the neurons of younger individuals.

"With age, these neurons face a double whammy, with an excessive calcium leak that initiates toxic actions, as well as diminished levels of the protectant, calbindin," said Arnsten.

Neurons in the prefrontal cortex require relatively high levels of calcium to perform their cognitive operations, but the calcium must be tightly regulated. However, as regulation is lost with increasing age, neurons become susceptible to tau pathology and degeneration. Essentially, neurons "eat" themselves from within.

"Understanding these early pathological changes may provide strategies to slow or prevent disease progression," Arnsten said.

Magic mushroom compound performs at least as well as leading antidepressant medication in small study

Imperial College London, April 14, 2021

Psilocybin, the active compound in magic mushrooms, may be at least as effective as a leading antidepressant medication in a therapeutic setting.

This is the finding of a study carried out by researchers at the Centre for Psychedelic Research at Imperial College London.

In the most rigorous trial to date assessing the therapeutic potential of a ‘psychedelic’ compound, researchers compared two sessions of psilocybin therapy with a six-week course of a leading antidepressant (a selective serotonin uptake inhibitor called escitalopram) in 59 people with moderate-to-severe depression.

The results, published today in the New England Journal of Medicine, show that while depression scores were reduced in both groups, the reductions occurred more quickly in the psilocybin group and were greater in magnitude.

However, the researchers caution that the main comparison between psilocybin and the antidepressant was not statistically significant. They add that larger trials with more patients over a longer period are needed to show if psilocybin can perform as well as, or more effectively than an established antidepressant.

For the psilocybin dosing sessions, volunteers received an oral dose of the drug in a specialist clinical setting, while they listened to a curated music playlist and were guided through their experiences by a psychological support team, which included registered psychiatrists. All volunteers on the study received the same level of psychological support.

People treated with psilocybin – named ‘COMP360’ by its developers, COMPASS Pathways PLC – showed marked improvements across a range of subjective measures, including in their ability to feel pleasure, and express emotions, greater reductions in anxiety and suicidal ideation, and increased feelings of wellbeing.

Dr Robin Carhart-Harris, head of the Centre for Psychedelic Research at Imperial, who designed and led the study, said: “These results comparing two doses of psilocybin therapy with 43 daily doses of one of the best performing SSRI antidepressants help contextualise psilocybin’s promise as a potential mental health treatment. Remission rates were twice as high in the psilocybin group than the escitalopram group.

“One of the most important aspects of this work is that people can clearly see the promise of properly delivered psilocybin therapy by viewing it compared with a more familiar, established treatment in the same study. Psilocybin performed very favourably in this head-to-head.”

GROWING EVIDENCE

During the study, 59 volunteers with moderate-to-severe depression received either a high dose of psilocybin and a placebo, or a very low dose of psilocybin and escitalopram. 

In the psilocybin arm of the trial, 30 people received an initial dose of psilocybin (25mg) at the start of the study, followed by a second dose (25mg) three weeks later. They were given six weeks of daily placebo capsules to take: one per day after the first dosing session, increasing to two per day after the second dosing session.  

In the escitalopram arm of the study, 29 people received 1mg psilocybin at the dosing sessions – a dose so low as to be classed as a non-active and unlikely to have an effect. They were also given six weeks of daily escitalopram: one 10mg capsule per day after the first dosing session, increasing to two per day after the second dosing session (20mg per day) – the maximum dose for this SSRI. 

All participants were assessed using standardised scales of depressive symptom severity. The main measure, the QIDS-SR-16, was used to gauge depressive symptoms on a continuous scale ranging from 0-27, where higher scores indicate greater depression. At the start of the trial, the mean score was 14.5 for the psilocybin group. But after six weeks, scores reduced by an average of 8.0 points.

Response, defined as a reduction in depression scores from baseline of at least 50%, was seen in 70% of people in the psilocybin group, compared with 48% in the escitalopram group. In addition, remission of symptoms – measured as a score of 0-5 at week six – was seen in 57% of the psilocybin group, compared with just 28% in the escitalopram group.

ENCOURAGING FINDINGS

The team highlights that while the findings are generally positive, the absence of a straight placebo group and the small number of participants limits conclusions about the effect of either treatment alone. They add that the trial sample was comprised of largely white, majority male, and relatively well-educated individuals, which limits extrapolations to more diverse populations. 

The psilocybin group reported fewer cases of dry mouth, anxiety, drowsiness and sexual dysfunction than the escitalopram group, and a similar rate of adverse events overall. Headaches experienced one day after dosing sessions were the most common side effect of psilocybin.

Dr Rosalind Watts, clinical lead of  the trial and formerly based at the Centre for Psychedelic Research, said: “Context is crucial for these studies and all volunteers received therapy during and after their psilocybin sessions. Our team of therapists were on hand to offer full support through sometimes difficult emotional experiences."

Professor David Nutt, principal investigator on the study and the Edmond J Safra Chair in Neuropsychopharmacology at Imperial, said: “These findings provide further support for the growing evidence base that shows that in people with depression, psilocybin offers an alternative treatment to traditional antidepressants.

“In our study, psilocybin worked faster than escitalopram and was well tolerated, with a very different adverse effects profile. We look forward to further trials, which if positive should lead to psilocybin becoming a licensed medicine.”

Magnesium has key role in keeping body clocks running on time

University of Edinburgh, April 13, 2021

An essential mineral in our diets has an unexpected role in helping living things remain adapted to the rhythms of night and day, scientists have found.

Magnesium - a nutrient found in many foods - helps control how cells keep their own form of time to cope with the natural environmental cycle of day and night.

The discovery in cells is expected to be linked to whole body clocks which influence daily cycles - or circadian rhythms - of sleeping and waking, hormone release, body temperature and other important bodily functions in people. The surprising discovery may aid the development of chronotherapy - treatment scheduled according to time of day - in people, and the development of new crop varieties with increased yields or adjustable harvesting seasons.

Experiments in three major types of biological organisms - human cells, algae, and fungi - found in each case that levels of magnesium in cells rise and fall in a daily cycle.

Scientists found that this oscillation was critical to sustain the 24-hour clock in cells. They were surprised to discover that it also had an enormous impact on metabolism in cells - how fast cells can convert nutrients into energy - throughout the course of a day.

Researchers at the University of Edinburgh and the MRC Laboratory for Molecular Biology in Cambridge used molecular analysis to find that concentrations of magnesium rose and fell in a 24-hour cycle in all cell types, and that this impacts on the cells' internal clocks.

Further tests showed that magnesium levels were linked to the cells' ability to burn energy. It was already known that magnesium is essential to help living things convert food into fuel, but scientists were surprised to discover that it also controls when this biological function takes place, and how efficiently.

Dr Gerben van Ooijen, of the University of Edinburgh's School of Biological Sciences, who led the study, said: "Internal clocks are fundamental to all living things. They influence many aspects of health and disease in our own bodies, but equally in crop plants and micro-organisms. It is now essential to find out how these fundamentally novel observations translate to whole tissue or organisms, to make us better equipped to influence them in complex organisms for future medical and agricultural purposes."

The study's other senior author, Dr John O'Neill of the MRC Laboratory of Molecular Biology in Cambridge, said: "Although the clinical relevance of magnesium in various tissues is beginning to garner more attention, how magnesium regulates our body's internal clock and metabolism has simply not been considered before. The new discovery could lead to a whole range of benefits spanning human health to agricultural productivity.

Exercise promotes healthy living and a healthy liver

Researchers show that in non-alcoholic fatty liver disease, regimented exercise has beneficial effects on the liver that are unrelated to weight loss and reveal the mechanisms underlying these benefits

University of Tsukuba (Japan), April 12, 2021

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder worldwide, affecting as much as a quarter of humanity. It is characterized by fat accumulation in liver cells and may progress to inflammation, cirrhosis and liver failure. Now, researchers at the University of Tsukuba reveal the positive effects, beyond the expected weight-loss benefit, of exercise on the liver. 

NAFLD is associated with unhealthy behaviors such as overeating and a sedentary lifestyle. In Japan 41% of middle-aged men have NAFLD and 25% will progress to non-alcoholic steatohepatitis (NASH) and hepatic dysfunction.

Weight reduction is fundamental to NAFLD management. Unfortunately, achieving a targeted bodyweight without supervision is difficult, and maintaining this over time even more so. Hitherto, exercise was considered adjunctive to dietary restrictions for weight loss but the other benefits such as reduced hepatic steatosis (fatty change) and stiffness are being increasingly recognized. However, the underlying mechanisms remain unclear.

"We compared data from obese Japanese men with NAFLD on a 3-month exercise regimen with those on dietary restriction targeting weight loss," senior author Professor Junichi Shoda explains. "We tracked hepatic parameters, reduction in adipose tissue, increase in muscle strength, reductions in inflammation and oxidative stress, changes in organokine concentrations, and expression of target genes of Nrf2, an oxidative stress sensor."

The researchers found that exercise preserved muscle mass better, though with modest decrease of body and fat mass. Remarkably, ultrasound elastography revealed that the exercise regimen reduced liver steatosis by an additional 9.5%, liver stiffness by an additional 6.8%, and the FibroScan-AST Score (a measure of liver fibrosis) by an additional 16.4% over the weight-loss regimen.

Additionally, the exercise regimen altered the circulating concentrations of specific organokines and apparently induced anti-inflammatory and anti-oxidative stress responses through activation of the Nrf2 (nuclear factor E2-related factor 2), an oxidative stress sensor. It also enhanced the phagocytic capacity of Kupffer cells which help maintain liver function.

Professor Shoda explains the relevance of their findings. "Our research shows how exercise prevents liver steatosis and fibrosis in NAFLD and clarifies that this benefit is compounded by preservation of muscle mass and is independent of weight changes. Patients on exercise regimens may become demotivated and drop out if they do not experience significant weight loss. Therefore, moderate to vigorous intensity exercise should be integrated in all NAFLD therapeutic regimens, and patients at risk for NASH should be encouraged to persevere with moderate to high intensity exercise regardless of whether or not they lose weight."

Research suggests quercetin can alleviate pulmonary arterial hypertension by regulating inflammatory cytokines

Zhejiang Provincial People’ s Hospital (China), April 9, 2021

According to news reporting originating in Zhejiang, People’s Republic of China, research stated, “This study aimed to investigate the effects of quercetin in the treatment of pulmonary arterial hypertension (PAH) in a murine model. Thirty-six adult male rats were randomly divided into three groups: the control group (saline), monocrotaline (MCT) - induced PAH group (MCT group) and quercetin treatment group (prevention group).”

The news reporters obtained a quote from the research from Zhejiang Provincial People’ s Hospital, “After modelling, the animals from prevention group received 100 mg/(kg bw/day quercetin by gavage and the gavage for 20 days, while the animals from the other two groups received the same amount of 0.9% sodium chloride saline solution. The mean pulmonary artery pressure, right ventricular index and relative expression levels of HIF-1 (hypoxia-inducible factor 1), ET-1(vascular endothelin-1), TGF-beta 1 (transforming growth factor-beta 1), VEGF (vascular endothelial growth factor), IL-1 (interleukin-1), IL-6 (interleukin-6) and TNF-alpha (tumour necrosis factor alpha) in lung tissues significantly increased in MCT group compared with the control group, 21 days after modelling. The levels of HGF (hepatocyte growth factor) and NAC (N-acetyl-L-cysteine) significantly increased compared with the control group. The treatment with quercetin significantly decreased the level of mean PAH, right ventricular index and relative expression levels of H1F-1, ET-1, TGF-beta 1, VEGF, IL-1, IL-6 and TNF-alpha in lung tissues compared with MCT group and significantly decreased the levels of HGF and NAC. In vitro experiment with PCEC (pulmonary capillary endothelial cells) from the three groups showed that in the MCT group the cell proliferation was significantly decreased and the apoptosis was significantly increased compared with the control group, while the quercetin treatment inhibited the MCT-induced cell apoptosis and promoted cell proliferation.”

According to the news reporters, the research concluded: “Quercetin can alleviate PAH by regulating the inflammatory cytokines, promoting cell proliferation and inhibition of cell apoptosis.”

This research has been peer-reviewed.

Intermittent fasting shown to provide broad range of health benefits in new study

Texas State University, April 7, 2021

Intermittent fasting may provide significant health benefits, including improved cardiometabolic health, improved blood chemistry and reduced risk for diabetes, new research conducted in part at Texas State University indicates. 

Matthew McAllister, assistant professor in the Department of Health and Human Performance, co-authored the study with Liliana Renteria, graduate research assistant in the Department of Health and Human Performance, along with Brandon Pigg and Hunter Waldman of the Department of Kinesiology at Mississippi State University. Their research, "Time-restricted feeding improves markers of Cardiometabolic health in physically active college-age men: A 4-week randomized pre-post pilot study," is published in the journal Nutrition Research (https://doi.org/10.1016/j.nutres.2019.12.001).

"What we are doing is time-restricted feeding. It is a way to use fasting each day to promote various aspects of cardiometabolic health," McAllister said. 

Time-restricted feeding (TRF) has been shown to improve body composition and blood lipids, as well as reduce markers of inflammation and oxidative stress. However, those results originated from rodent models and studies with small human samples. In the Texas State study, 22 men were divided into two groups to complete a 28-day study. Subjects ate daily during one eight-hour period, for example, between 9 a.m. and 5 p.m. or between noon and 8 p.m. For 16 hours of the day, they did not eat or drink anything other than water. 

While both groups underwent TRF, one group's caloric intake was controlled during meal periods to ensure they ate the same amount as before the study, while members of the other group were allowed to eat as much as they wanted. 

"My initial thought was that if you are going to restrict the time, you would eat fewer calories. And the reduction of daily calories would cause weight loss and other health benefits," McAllister said. "But these benefits are found with no change in caloric intake—things like loss in body fat, reduced blood pressure, reduced inflammation.”

Fasting blood samples were analyzed for glucose and lipids, as well as adiponectin, human growth hormone, insulin, cortisol, c-reactive protein, superoxide dismutase, total nitrate/nitrite and glutathione. Results showed that both groups experienced significant reductions in body fat, blood pressure and significant increases in adiponectin and HDL-c. No change in caloric intake was detected among members of either group.

The COVID-19 pandemic has been linked with six unhealthy eating behaviors

University of Minnesota Medical School, April 12, 2021

A new probe into the lingering impacts of the COVID-19 pandemic revealed correlations to six unhealthy eating behaviors, according to a study by the University of Minnesota Medical School and School of Public Health. Researchers say the most concerning finding indicates a slight increase or the re-emergence of eating disorders, which kill roughly 10,200 people every year -- about one person every 52 minutes.

U of M Medical School's Melissa Simone, PhD, a postdoctoral research fellow in the Department of Psychiatry and Behavioral Sciences, collaborated with School of Public Health professor and head of the Division of Epidemiology and Community Health, Dianne Neumark-Sztainer, PhD, MPH, to learn from study participants in Neumark-Sztainer's Project EATbetween April and May 2020.

"The COVID-19 pandemic has resulted in the rapid implementation of public health policies to reduce transmission of the virus. While these protections are necessary, the disruptions to daily life associated with the ongoing pandemic may have significant negative consequences for the risk of eating disorders and symptoms," said Simone, who is the lead author of the study. "Eating disorders have one of the highest mortality rates across all psychiatric health concerns, and therefore, it is important to try to make links between the consequences of the pandemic and disordered eating behaviors.

The study aimed to understand potential associations between stress, psychological distress, financial difficulties and changes in eating behaviors during the COVID-19 pandemic through the analysis of both qualitative and quantitative data. Simone's findings, published in theInternational Journal of Eating Disorders, found six key themes of eating behavior changes:

• Mindless eating and snacking;
• Increased food consumption;
• Generalized decrease in appetite or dietary intake;
• Eating to cope;
• Pandemic-related reductions in dietary intake;
• And, a re-emergence or marked increase in eating disorder symptoms.

Approximately 8% of those studied reported extreme unhealthy weight control behaviors, 53% had less extreme unhealthy weight control behaviors and 14% reported binge eating. The study revealed that these outcomes were significantly associated with poorer stress management, greater depressive symptoms and moderate or extreme financial difficulties.

"There has been a lot of focus on obesity and its connection with COVID-19. It is also important to focus on the large number of people who have been engaging in disordered eating and are at risk for eating disorders during and following the pandemic," said Neumark-Sztainer, who is the principal investigator of Project EAT. "The majority of the young adults in our study are from diverse ethnic/racial and lower income backgrounds, who often do not receive the services they need. To ensure health inequities do not increase, we need to meet the needs of these populations."

Simone added, "The economic consequences of the COVID-19 pandemic will likely persist long beyond the dissemination of a vaccine. Because our findings suggest that moderate or severe financial difficulties may be linked with disordered eating behaviors, it is essential that eating disorder preventive interventions and treatment efforts be affordable, easily accessible and widely disseminated to those at heightened risk. As such, online or mobile-based interventions may prove to be effective and accessible modes for targeted intervention efforts."

This study was funded by the National Heart, Lung, and Blood Institute (R01HL116892, R35HL139853: Principal Investigator: D. Neumark-Sztainer), the National Center for Advancing Translational Sciences (TL1R002493, UL1TR002494), and the National Institute of Mental Health (T32MH082761).

Ginseng and anti-obesity: Does Asian variety offer greater weight loss hope?

Tennessee State University, April 5, 2021

Studies comparing the differing anti-obesity effects of Asian and American ginseng are urgently needed, it has been claimed, not least because they are thought to have opposite medical effects in Traditional Chinese Medicine (TCM).

Writing in a review in the Journal of Nutritional Biochemistry, scientists from Tennessee State University said a number of investigations had been conducted on ginseng in preventing and treating of obesity.

However, the effect and the relevant mechanisms behind how ginseng works as an anti-obesity treatment are still controversial, they added, and the issue is clouded by the differing uses of American and Asian ginseng in TCM.

The former is used to treat yin manifestations of Qi (life energy), while the latter tackle yang manifestations. Therefore, Asian ginseng has often been used to help treat, fatigue, poor appetite, diarrhoea, breath shortness, feeble pulse, spontaneous perspiration, febrile diseases, amnesia, insomnia and impotence.

On the other hand, American ginseng is used to treat diseases such as cough, blood sputum, dysphoria, fatigue and thirst.

“Although the potential anti-obesity effect of Asian ginseng has been investigated in mice and humans in Asia in the last several decades, the anti-obesity effect and mechanism of ginseng are still not fully understood, especially in humans,” wrote the researchers. “Moreover, high-quality studies of the effects of ginseng in the United States are rare, particularly whether and how American ginseng prevents obesity is almost blank.”

They said this was area ripe for further investigation, and pointed to their own unpublished data which showed that while Asian ginseng significantly inhibited fat accumulation in 3T3-L1 cells, American ginseng has no such effect at the same concentration (1 mg/ml). They suggest this could be due increased fat accumulation caused by one of the major ginsenosides in American ginseng that is not detectable in Asian ginseng

“The different anti-obesity effect between American ginseng and Asian ginseng may also result from the different profiles of other ginsenosides,” they added.

“There is only one study showing that Asian ginseng extract intake exerted a weight loss effect in obese women,” they wrote. “American ginseng extract or whole plant/berry has not been investigated for anti-obesity in humans. In addition, there is no report using human primary cells investigating the antiobesity effect of ginseng and ginsenosides.”

They argue that standardised ginseng production is sorely needed to overcome the fact that the results of existing studies “are controversial”.

“These controversial results at least partly come from the variety of the quality of ginseng, especially the whole extract and juice. The quantity and composition of ginsenosides in ginseng plants are dramatically influenced by species, age, and part of the plant, cultivation methods, harvesting season, preservation methods and geographical distribution,” they state. “However, almost all ginsenosides or extracts in these studies were prepared in the individual labs or from different companies, it is almost impossible to keep the quality at the same level, particularly the whole extract.”

The authors concluded; “Although Asian and American ginsengs have similar profiles of active ingredients, the different percentage of crude saponins (4.8%–5.2% in Asian ginseng vs. 7.0%–7.3% in American ginseng) and the specific ginsenoside (Rf only in Asian ginseng, F11 only in American ginseng) may contribute to the different functions of these two ginsengs.” “Therefore, it is very important to compare the medical effects using modern scientific approaches.”

Study links prenatal phthalate exposure to altered information processing in infants

University of Illinois, April 6, 2021

Exposure to phthalates, a class of chemicals widely used in packaging and consumer products, is known to interfere with normal hormone function and development in human and animal studies. Now researchers have found evidence linking pregnant women's exposure to phthalates to altered cognitive outcomes in their infants.

Most of the findings involved slower information processing among infants with higher phthalate exposure levels, with males more likely to be affected depending on the chemical involved and the order of information presented to the infants.

Reported in the journal Neurotoxicology, the study is part of the Illinois Kids Development Study, which tracks the effects of hormone-disrupting chemicals on children's physical and behavioral development from birth to middle childhood. Now in its seventh year, IKIDS has enrolled hundreds of participants and is tracking chemical exposures in pregnant women and developmental outcomes in their children. Susan Schantz, a neurotoxicologist and professor emerita of comparative biosciences at the University of Illinois Urbana-Champaign, is the principal investigator of the study. She is a faculty member in the Beckman Institute for Advanced Science and Technology, which houses the IKIDS program at Illinois.

"IKIDS is part of a larger initiative funded by the National Institutes of Health, the Environmental Influences on Child Health Outcomes program. It is tracking the impact of prenatal chemical exposures and maternal psychosocial stress on children's growth and development over time," Schantz said. "We measure numerous birth outcomes, including birth weight and gestational age. We also assess infants' cognition by studying their looking behavior. This allows us to get measures of working memory, attention and information-processing speed."

The researchers analyzed metabolites of three commonly occurring phthalates in urine samples regularly collected from the pregnant women in the study. The chemical exposure data were used in combination with assessments of the women's infants when the children were 7.5 months old.

The researchers used a well-established method that gives insight into the reasoning of children too young to express themselves verbally: Infants typically look longer at unfamiliar or unexpected images or events.

The team used an infrared eye-tracker to follow each infant's gaze during several laboratory trials. With the infant sitting on a caregiver's lap, researchers first familiarized the child with two identical images of a face. After the infant learned to recognize the face, the researchers showed that same face paired with an unfamiliar one.

"In repeated trials, half of the 244 infants tested saw one set of faces as familiar, and half learned to recognize a different set of faces as familiar," Schantz said. "By analyzing the time spent looking at the faces, we could determine both the speed with which the infants processed new information and assess their ability to pay attention."

The assessment linked pregnant women's exposure to most of the phthalates that were assessed with slower information processing in their infants, but the outcome depended on the specific chemical, the sex of the infant and which set of faces the infant viewed as familiar. Male infants, in particular, tended to process information more slowly if their mothers had been exposed to higher concentrations of phthalates known to interfere with androgenic hormones.

The specific characteristics of faces presented to the infants in the familiarization trials also appeared to play a role in the outcome, the researchers reported. Phthalate-exposed children who were first familiarized with faces from Set 2 were more likely to experience slower processing speed than those familiarized with faces from Set 1. The finding is perplexing, Schantz said, but is likely related to differences in the infants' preferences for the faces in the two sets. It also may be an indication that familiarization with the Set 2 faces is a more sensitive detector of changes in processing speed related to phthalate exposure.

"Most previous studies of the relationship between prenatal exposure to phthalates and cognition have focused on early and middle childhood," Schantz said. "This new work suggests that some of these associations can be detected much earlier in a child's life."

Heart failure and stroke rising in men under 40

University of Gothenburg (Germany), April 8, 2021

Heart failure and stroke are unusual diagnoses among younger people. But they are now clearly on the rise in men below the age of 40, according to a University of Gothenburg study. The scientists have found links to obesity and low fitness in the upper teens.

The present study, published in Journal of Internal Medicine, includes data on 1,258,432 men who, at an average age of 18.3 years, enlisted for military service in Sweden between 1971 and 1995.

Particulars of the men's weight, height and physical fitness on enlistment were merged with data in the National Board of Health and Welfare's National Patient Register and Cause of Death Register for the period 1991-2016. From when they enlisted, the men were thus monitored over a period exceeding 20 years.

The proportion of participants who were overweight at the time of enlistment, i.e. with a body mass index (BMI) of 25-30, increased from 6.6 to 11.2 percent between 1971 and 1995, while the proportion with obesity (BMI over 30) rose from 1.0 to 2.6 percent. During the same period, their fitness level at the time of enlistment also declined slightly.

"These factors -- that is, overweight, obesity and low fitness -- partly explain the large increase in heart failure we see in the study, and the rise in stroke as well," states David Åberg. An Associate Professor at Sahlgrenska Academy, University of Gothenburg, and specialist doctor at Sahlgrenska University Hospital, Åberg is the study's first author.

"It's pleasing to see, despite rising obesity, a fairly sharp fall in heart attacks among these younger men, and also their reduced mortality from cardiovascular diseases," he continues.

Heart-failure cases within 21 years of enlistment rose, according to the study, by 69 percent -- from 0.49 per 1,000 of the men who had enlisted in the first five years (1971-75) to 0.83/1,000 of those who enlisted in the last five (1991-95).

The number of stroke cases -- cerebral infarction and cerebral hemorrhage -- showed a similar trend. The increase for cerebral infarction was 32 percent, from 0.68 for the first five-year cohort to 0.9 per 1,000 for the last. For cerebral hemorrhage the rise was 20 percent, from 0.45 to 0.54 per 1,000.

In contrast, heart attacks within 21 years of enlistment fell by 43 percent, from 1.4 to 0.8 per 1,000, of the cohorts enlisting first and last respectively. The proportion of deaths from all cardiovascular disease also decreased, by 50 percent -- from 1.5 to 0.74 per 1,000.

The fact that the trends for cardiovascular diseases move in differing directions over time suggests that other, unknown factors are involved as well. According to the researchers, post-enlistment weight trends may be one such factor, but stress and drug use may be others. Especially for heart attacks, researchers believe that a sharp fall in smoking underlies the decline. The fact remains, however, that overweight and obesity are influential.

"We see that heart attacks would have decreased even more if it hadn't been for the rise in overweight and obesity. Our results thus provide strong support for thinking that obesity and, to some extent, low fitness by the age of 18 affect early-onset cardiovascular disease. So at societal level, it's important to try to get more physical activity, and to have already established good eating habits by adolescence, while being less sedentary," David Åberg concludes.

Clinical trial shows benefit of yoga for side effects of prostate cancer treatment

University of Pennsylvania, April 7, 2021

Men who attended a structured yoga class twice a week during prostate cancer radiation treatment reported less fatigue and better sexual and urinary function than those who didn't, according to a clinical trial led by the Perelman School of Medicine at the University of Pennsylvania. It is the first randomized trial to look at the effect of twice-weekly yoga on the side-effects and quality of life issues caused by prostate cancer treatment. The results published in the International Journal of Radiation Oncology, Biology, and Physics.

All of the patients in the trial underwent between six and nine weeks of external beam radiation therapy for prostate cancer. The patients were randomized into two groups: one arm participated in a yoga class that met twice a week and the other arm served as a control group. Patients who already practiced yoga on their own were not eligible for the study, nor were patients with a history of prior radiation therapy or those with metastatic disease.

Only two instructors led classes for this study, with the lead instructor teaching 75 percent of the classes. Each session lasted 75 minutes, beginning with five minutes of breathing and centering techniques and ending with five minutes of Savasana, a common yoga position. Typical sessions incorporated sitting, standing, and reclining positions that were modified using props to adapt to each patient's needs and restrictions.

Patients were primarily evaluated on their level of fatigue. Each man filled out a nine-item questionnaire assessing fatigue severity and impact on daily life. The first questionnaire was given between two and three weeks before the start of radiotherapy, then twice a week while receiving radiotherapy, with a final survey filled out within a week of their last yoga class or last radiation treatment, depending on the assigned study arm.

"At their baseline, before patients started treatment, patients in both groups were on the lower end of the scale, meaning they reported lower amounts of fatigue," said the trial's principal investigator Neha Vapiwala, MD, an associate professor of Radiation Oncology. "But as treatment went on, we observed a difference in the two groups." Patients in the yoga group reported lower fatigue scores over time, as they attended more yoga sessions, relative to where they started. Patients who did not participate in yoga trended in the opposite direction, reporting greater fatigue as treatment progressed.

"Levels of patient-reported fatigue are expected to increase by around the fourth or fifth week of a typical treatment course, but that did not happen in the yoga group," Vapiwala said. "Both the severity of the fatigue as well as the patients' ability to go about their normal lives appeared to be positively impacted in the yoga group."

Researchers also evaluated both groups in terms of their sexual health. Sexual dysfunction - including but not limited to erectile dysfunction (ED) - is reported by up to 85 percent of radiation therapy patients during treatment, often due to the concurrent use of androgen deprivation therapy (ADT). The study utilized the International Index of Erectile Function (IIEF) questionnaire, in which scores range from 0-25. Scores greater than 21 are considered normal and scores below 12 indicate moderate to severe ED. Both groups started out with scores of around 11, and were balanced in terms of ADT exposure; but while the yoga group's score ended up largely unchanged from baseline, the non-yoga group saw a decline over the course of treatment.

"Yoga is known to strengthen pelvic floor muscles, which is one of several postulated theories that may explain why this group did not demonstrate declining scores, as seen in the control group," Vapiwala said. "That may also explain the yoga patients' improved urinary function scores, another finding of this trial." Vapiwala pointed out that the findings on improved or stable urinary function are consistent with other research on the effects of physical therapy on pelvic floor muscles.

The trial also found that while the emotional well-being of both groups increased as patients progressed through treatment, the evaluation scores in the yoga group rose more rapidly than in the control group. An evaluation of physical well-being showed a similar pattern

Spanking may affect the brain development of a child

Study shows it could alter a child's neural responses to their environment in similar ways to a child experiencing more severe violence

Harvard University, April, 12, 2021

Spanking may affect a child's brain development in similar ways to more severe forms of violence, according to a new study led by Harvard researchers. 

The research, published recently in the journal Child Development, builds on existing studies that show heightened activity in certain regions of the brains of children who experience abuse in response to threat cues. 

The group found that children who had been spanked had a greater neural response in multiple regions of the prefrontal cortex (PFC), including in regions that are part of the salience network. These areas of the brain respond to cues in the environment that tend to be consequential, such as a threat, and may affect decision-making and processing of situations.

"We know that children whose families use corporal punishment are more likely to develop anxiety, depression, behavior problems, and other mental health problems, but many people don't think about spanking as a form of violence," said Katie A. McLaughlin, John L. Loeb Associate Professor of the Social Sciences, director of the Stress & Development Lab in the Department of Psychology, and the senior researcher on the study. "In this study, we wanted to examine whether there was an impact of spanking at a neurobiological level, in terms of how the brain is developing."

According to the study's authors, corporal punishment has been linked to the development of mental health issues, anxiety, depression, behavioral problems, and substance use disorders. And recent studies show that approximately half of parents in U.S. studies reported spanking their children in the past year and one-third in the past week. However, the relationship between spanking and brain activity has not previously been studied. 

McLaughlin and her colleagues--including Jorge Cuartas, first author of the study and a doctoral candidate in the Harvard Graduate School of Education, and David Weissman, a post-doctoral fellow in the Department of Psychology's Stress & Development Lab--analyzed data from a large study of children between the ages of three and 11. They focused on 147 children around ages 10 and 11 who had been spanked, excluding children who had also experienced more severe forms of violence. 

Each child lay in an MRI machine and watched a computer screen on which were displayed different images of actors making "fearful" and "neutral" faces. A scanner captured the child's brain activity in response to each kind of face, and those images were analyzed to determine whether the faces sparked different patterns of brain activity in children who were spanked compared to those who were not. 

"On average, across the entire sample, fearful faces elicited greater activation than neutral faces in many regions throughout the brain... and children who were spanked demonstrated greater activation in multiple regions of PFC to fearful relative to neutral faces than children who were never spanked," researchers wrote. 

By contrast, "(t)here were no regions of the brain where activation to fearful relative to neutral faces differed between children who were abused and children who were spanked."

The findings are in line with similar research conducted on children who had experienced severe violence, suggesting that "while we might not conceptualize corporal punishment to be a form of violence, in terms of how a child's brain responds, it's not all that different than abuse," said McLaughlin. "It's more a difference of degree than of type."

Researchers said the study is a first step towards further interdisciplinary analysis of spanking's potential effects on children's brain development and lived experiences. 

"These findings aligned with the predictions from other perspectives on the potential consequences of corporal punishment," studied in fields such as developmental psychology and social work, said Cuartas. "By identifying certain neural pathways that explain the consequences of corporal punishment in the brain, we can further suggest that this kind of punishment might be detrimental to children and we have more avenues to explore it."

However, they noted that their findings are not applicable to the individual life of each child. 

"It's important to consider that corporal punishment does not impact every child the same way, and children can be resilient if exposed to potential adversities," said Cuartas. "But the important message is that corporal punishment is a risk that can increase potential problems for children's development, and following a precautionary principle, parents and policymakers should work toward trying to reduce its prevalence." 

Ultimately, added McLaughlin, "we're hopeful that this finding may encourage families not to use this strategy, and that it may open people's eyes to the potential negative consequences of corporal punishment in ways they haven't thought of before."

Sufficient vitamin D during gestation and early life can lower susceptibility to allergy in infants

Wageningen University (Netherlands), April 5, 2021

According to news originating from Wageningen, Netherlands, the research stated, “Worldwide, the prevalence of allergies in young children, but also vitamin D deficiency during pregnancy and in newborns is rising. Vitamin D modulates the development and activity of the immune system and a low vitamin D status during pregnancy and in early life might be associated with an increased risk to develop an allergy during early childhood.”

Our news editors obtained a quote from the research from Wageningen University and Research: “This review studies the effects of vitamin D during gestation and early life, on allergy susceptibility in infants. The bioactive form of vitamin D, 1,25(OH)2D, inhibits maturation and results in immature dendritic cells that cause a decreased differentiation of naive T cells into effector T cells. Nevertheless, the development of regulatory T cells and the production of interleukin-10 was increased. Consequently, a more tolerogenic immune response developed against antigens. Secondly, binding of 1,25(OH)2D to epithelial cells induces the expression of tight junction proteins resulting in enhanced epithelial barrier function. Thirdly, 1,25(OH)2D increased the expression of anti-microbial peptides by epithelial cells that also promoted the defense mechanism against pathogens, by preventing an invasive penetration of pathogens.”

According to the news editors, the research concluded: “Immune intervention by vitamin D supplementation can mitigate the disease burden from asthma and allergy. In conclusion, our review indicates that a sufficient vitamin D status during gestation and early life can lower the susceptibility to develop an allergy in infants although there remains a need for more causal evidence.”

Training in compassion improves the well-being of relatives to people with mental illness

Aarhus University (Denmark), April 7, 2021

If relatives of people with mental illness become better at accepting the difficult emotions and life events they experience - which is what training in compassion is about - their anxiety, depression and stress is reduced. These are the results of a new study from the Danish Center for Mindfulness at Aarhus University.

Being a relative of a person with a mental illness can be very burdensome. It can feel like a great responsibility, and many people struggle with feelings of fear, guilt, shame and anger. A new study from the Danish Center for Mindfulness shows that eight weeks of training in compassion can significantly improve the well-being of relatives. 

Compassion is a human quality that is anchored in the recognition of and desire to relieve suffering. In other words, compassion occurs when we come into contact with our own or others' suffering and feel motivated to relieve our own or others pain.

"After completing the course, the relatives had increased their well-being on several parameters. They could deal with the illness in a new and more skillful way, and we saw that the training reduced their symptoms of depression, anxiety and stress," says psychologist and PhD student Nanja Holland Hansen, who is behind the study.

And the positive results were maintained after a six month follow-up. 

Trying to fix what is difficult

"The relatives learned that the more they turn towards what is difficult, the more skillful they may act. For example, relatives often try to 'fix' the problem or the challenge - so as to relieve their loved ones of what is difficult. That's a huge pressure to constantly deal with, and very few people can bear it," says Nanja Holland Hansen. 

Living with chronic fear

She goes on to explain that training in compassion helps people to find the strength and courage to bear pain and suffering when life is difficult. It may seem both sensible and intuitive to guard yourself from the confrontation or avoid what is difficult and unpleasant. But this is the paradox of the training, explains the researcher. Because it is precisely actions and thoughts like these that shut down our compassion and thereby maintain the suffering. 

"Fear and grief are emotions that take up a lot space for relatives of people with mental illness. For example chronic fear, which is a real fear that parents of a child with schizophrenia have about whether their child is going to commit suicide, or whether a child with autism will ever enjoy a 'normal life'," explains Nanja Holland Hansen and continues:

"Our suffering is maintained inside of us when we don't work with it. To avoid feeling pain, we may resort to behaviour such as working too much or buying things that we don't need. It's therefore in all these everyday actions that our compassion training becomes important and can be used to help alleviate what is difficult," she says.

No one escapes

The purpose of training in compassion is thus more than just feeling empathy or worrying about another person. 

"Not a single person can completely avoid experiencing painful things in their life. In this way we're all the same. But what isn't the same for everyone is our ability to deal with the pain and suffering we experience. Training programmes in compassion have been developed because the research shows that we can train and strengthen our mental health. With systematic training of compassion, we generate more attention - and understanding of - our own thoughts, feelings and behaviour. And this helps us to develop the tools and skills to engage in healthier relations with ourselves and others," she explains. 

A total of 161 relatives of people with mental illness participated in the study. This makes the study one of the largest of its kind in the world, and also the first scientific randomised clinical trial carried out with relatives in Denmark. The relatives were between 18 and 75 of age and were family members to people with various psychiatric disorders such as e.g. ADHD, schizophrenia and depression. 

Meditation as homework

The relatives met once a week in groups of twenty participants over an eight-week period. Each session lasted two hours and was structured with small group exercises, large group discussions, instruction in the theme of the week and meditation. The homework consisted of twenty minutes of daily meditation.

"There is definitely a shortage of offers for these relatives. They're often told that they should remember to take care of themselves, but they haven't learned how to. We found that those who were involved in the study received the tools for precisely this," says Nanja Holland Hansen.

The results have just been published in the scientific journal JAMA.

"My hope is that local authorities and regions can offer this type of intervention for relatives. It should be an option and could easily be incorporated into our healthcare system. Economically and socially, a healthy person going on sick leave solely because he or she is a relative is a huge loss," says the researcher.

[Billedtekst:]: "Up to fifty percent of relatives of people with mental illness risk becoming ill themselves. That's why it's important that we also keep them and their well-being in mind," says Nanja Holland Hansen.

Sesaminol prevents Parkinson's disease by activating the Nrf2-ARE signaling pathway

Osaka City University (Japan), March 331, 2021

Parkinson's disease (PD) is a neurodegenerative disease caused by the degeneration of substantia nigra neurons due to oxidative stress. Sesaminol has strong antioxidant and anti-cancer effects. We investigated the preventive effect on PD as a new physiological action of sesaminol produced from sesaminol glycoside using in vitro and in vivo PD models. To prepare an in vitro PD model, 6-hydroxydopamine (6-OHDA) was added to human neuroblastoma (SH-SY5Y cells). The viability of SH-SY5Y cells decreased dose-dependently following 6-OHDA treatment, but the addition of sesaminol restored viability to the control level. 6-OHDA increased intracellular reactive oxygen species production, and the addition of sesaminol significantly suppressed this increase. No Nrf2 expression in the nucleus was observed in the control group, but a slight increase was observed in the 6-OHDA group. The sesaminol group showed strong expression of Nrf2 in the cytoplasm and nucleus. NAD(P)H: quinone oxidoreductase (NQO1) activity was enhanced in the 6-OHDA group and further enhanced in the sesaminol group. Furthermore, the neurotoxine rotenone was orally administrated to mice to prepare an in vivo PD model. The motor function of rotenone-treated mice was shorter than that of the control group, but a small amount of sesaminol restored it to the control level. The intestinal motility in the rotenone group was significantly lower than that in the control group, but it remained at the control level in the sesaminol group. The expression of α-synuclein in the substantia nigra increased in the rotenone group but decreased in the sesaminol group. The rotenone group exhibited shortening and damage to the colonic mucosa, but these abnormalities of the colonic mucosa were scarcely observed in the sesaminol group. These results suggest that sesaminol has a preventative effect on PD.

Study finds connection between lifestyle choices, Alzheimer disease

Brigham Young University, April 8, 2021

A recent study out of BYU has linked lifestyle choice to Alzheimer's disease, at least to some degree, through findings that show a possible energy gap between the amount of glucose and ketones being used to power the brain.

BYU professor Ben Bikman, who studies diabetes and insulin resistance, thought of a fundamental question surrounding Alzheimer's disease and insulin resistance in the brain.

Bikman said there has been growing evidence that the brains in humans with Alzheimer's disease are deficient in the use of glucose.

"The brain has a certain energy demand, let's say that is 100%," Bikman said. "In most instances, glucose is providing virtually all of that energy, nearly 100% all of the time. There is a secondary fuel known as ketones, so the average brain is consuming almost all of its energy from glucose with a little bit of energy coming from ketones at any moment. In some individuals, the brain starts to become deficient in its ability to use glucose. So now glucose can only provide about 60% of that energy, and then ketones would be expected to fill up the rest of that energy. The tragedy is that the average individual has almost undetectable levels of ketones and that's entirely a matter of lifestyle."

This lack of ketones as well as the brain's resistance to insulin is linked to lifestyle. Insulin is expected to stimulate tissues or cells to take in the glucose and use it for energy.

As the brain becomes more insulin resistant, it can't take in glucose anymore and this is something Bikman said has been shown in other research. The BYU research expanded on some of those findings.

"We found that indeed the expression of genes involved in glucose metabolism was significantly down, very broad across every cell type we looked at in the brain," Bikman said. "All of the cell types we looked at had significant reductions in glucose-related genes, but the ketone-related genes were almost totally normal."

This is key because it shows that if the brain can receive more ketones, there is a possibility that one could overcome that energy gap. While it may not be able to be filled in with glucose, it can be with ketones but ketones need to be produced by one's body.

With many people having diets that are high in refined sugars and starches, insulin is elevated all of the time, and ketones are only produced when insulin levels are low. These conditions include fasting or low-carb diets, also known as keto diets.

Ph.D. student Erin Saito is another one of the lead authors of the study and is doing this project as her dissertation. Another collaborator included Washington University of Saint Louis, which gave the BYU research team access to various brain banks.

"BYU is a wonderfully collaborative environment, not only encouraging collaborations within the university but also outside of the university," Bikman said. "Thus communicating with our internal and external collaborators was very easy and very natural. There was very much a common interest to work on this project together, a common enthusiasm for answering a question that had not been asked yet. It would not have been possible without that mutual collaboration and enthusiasm."

He added that managing the project with enthusiastic students was a delight, making it easy because of the enthusiasm surrounding the project.

Bikman said it is gratifying for him to be able to contribute to what little is known about Alzheimer's disease, because traditional strategies and approaches have continued to fail.

"Looking at Alzheimer's disease as a metabolic problem, I would say, is the greatest breakthrough in our understanding of the disease in decades," Bikman said.

Looking at it through the metabolic side of things allows people to possibly detect the problem years in advance, looking at changes in brain glucose metabolism long before Alzheimer's sets in.

Bikman believes that someday the metabolic approach to Alzheimer's will be the standard of care.

Moving forward, Bikman said he hopes that people feel empowered when it comes to Alzheimer's disease. He wants people to not look at it as a passive process where they are the victim, but rather acknowledging that their lifestyle choices can either act as the culprit or the cure.

"For too long we have viewed Alzheimer's disease as a disease that is no respecter of person, no respecter of choices and that is simply not true," Bikman said. "We have long known that people with metabolic disorders, like type 2 diabetes and insulin resistance, are at significantly greater risk of developing Alzheimer's disease and we have more evidence suggesting that dietary choices and changes do make significant improvements in someone's cognition."

Even someone in the midst of Alzheimer's disease can see improvements in memory and learning with a lifestyle change, according to Bikman, and he added that he hopes this evidence will help to strengthen that view and empower individuals to take matters into their own hands.

New Study Shows Broad Benefits Of High-CBD Cannabis

Health Canada Research Institute, April 6, 2021

With CBD exploding in popularity, new studies continue to reveal its potential benefits.

A new study published in the journal Aging-US reported that high-CBD cannabis has anti-inflammatory and anti-cancer properties and may even help reduce COVID symptoms.

Cannabidiol, or CBD, is a non-psychoactive compound in cannabis and is legal in all 50 states.

“Cannabis sativa, especially those high in the anti-inflammatory cannabinoid cannabidiol, has been found to alter gene expression and inflammation and harbour anti-cancer and anti-inflammatory properties,” the researchers at Health Canada concluded.

As such, they say specific CBD extracts “may become a useful and safe addition to the prevention/treatment of COVID-19 as an adjunct therapy.”

Researchers hypothesized that high-CBD C. sativa extracts may be used to down-regulate ACE2 expression in target COVID-19 tissues. Using artificial 3D human models of oral, airway and intestinal tissues, they identified 13 high-CBD C. sativa extracts that decrease ACE2 protein levels. Some C. sativa extracts down-regulate serine protease TMPRSS2, another critical protein required for SARS-CoV-2 entry into host cells.

This is not the first study to suggest that CBD could combat respiratory illnesses like COVID.

In April 2020, researchers at the University of Nebraska and the Texas Biomedical Research Institute published a peer-reviewed article suggesting that CBD could be included in the treatment regimen for the COVID-19 coronavirus as THC and CBD both appeared to reduce the severe lung inflammation associated with the virus.

In July 2020, researchers at the Dental College of Georgia and Medical College of Georgia found early evidence that Cannabidiol, or CBD, may help reduce the cytokine storm and excessive lung inflammation that killed many patients with COVID-19.

“Our laboratory studies indicate pure CBD can help the lungs recover from the overwhelming inflammation, or cytokine storm, caused by the COVID-19 virus, and restore healthier oxygen levels in the body,” says co-author Dr. Jack Yu, physician-scientist and chief of pediatric plastic surgery at MCG.

In October 2020, the same research group published a follow-up peer-reviewed study identifying the mechanism they believe was responsible for the encouraging results of using CBD to reduce lung inflammation.

“One way CBD appears to reduce the “cytokine storm” that damages the lungs and kills many patients with COVID-19 is by enabling an increase in levels of a natural peptide called apelin, which is known to reduce inflammation and whose levels are dramatically reduced in the face of this storm,” they concluded.

While this is incredibly encouraging news for relief from COVID, businesses that sell CBD edibles and oils are not allowed to mention these benefits in advertising because the FDA has not officially approved it for any specific treatment. Apparently, experimental vaccines are okay to advertise but natural plant extracts aren’t.

The new study above is just another to suggest cannabis and CBD can help fight cancer. There have been many studies as well as countless confirmed anecdotal accounts.

In 2018, a 44-year-old UK mom refused chemo for her aggressive triple-negative breast cancer. She opted for CBD oil instead and was declared cancer-free five months later.

In 2019, an 81-year-old diagnosed with lung cancer shrunk his tumors in half by taking CBD oil. The case study was published in the peer-reviewed journal Sage.

More recently, a Colorado State University study showed that CBD extract can slow growth and kill cancer cells in aggressive brain cancer.

“Our experiments showed that CBD slows cancer cell growth and is toxic to both canine and human glioblastoma cell lines,” said Chase Gross, a doctoral student participating in the study. “Importantly, the differences in anti-cancer affects between CBD isolate and extract appear to be negligible.”

That’s not all, CBD has shown potential for treating a variety of other ailments such as arthritis, seizures, chronic pain, high blood pressure, Alzheimer’s and more – with little to no severe side effects that are common with leading pharmaceuticals.

Big Pharma hopes more people don’t discover natural treatments to common health issues, like CBD, because it could severely impact their profits and influence.

Polyphenol pills counter inflammation in women on hormonal contraceptives: RCT

Universidade Federal do Rio Grande do Sul (Brazil), April 7, 2021

Supplements containing a mixture of polyphenols may counter increases in pro-inflammatory markers in women of childbearing age using combined hormonal contraceptives, says a new study.

The supplements, formulated with resveratrol, catechin, quercetin, chlorogenic acid and cyanidin, were also found to prevent the increases in markers of systemic oxidative stress like F2-isoprostane, according to findings published in Prostaglandins, Leukotrienes and Essential Fatty Acids .

“The increase in biomarkers of inflammation and oxidative stress observed in the present study were possibly caused by the use of hormonal contraceptives, as verified in the [control group], and this change was not observed in the group that used polyphenols,” wrote researchers from the Institute of Cardiology and the Universidade Federal do Rio Grande do Sul in Brazil.

“Therefore, the results of this polyphenol supplementation showed that the antioxidant and anti-inflammatory effects observed in the studied population is due to the reduction in plasma levels of PGE2, supporting the conceptual hypothesis, by its action on the inflammatory cascade, probably by COX inhibition.”

Study details

The Brazil-based researchers recruited 40 women aged between 25 and 35 using contraceptives, and randomly assigned them to receive either placebo or polyphenols (3,000 mg per day) for 15 days. “A higher dosage was chosen in order to reduce the risk of food ingestion of control group to overcome the dosage of polyphenol supplementation in the [polyphenol group],” they explained.

Data from the 28 women who completed the study indicated that, as expected, markers of inflammation (PGE2 and C-reactive protein) and oxidative stress (F2-isoprostane) increased significantly in women in the placebo group. However, no such increases were observed in the polyphenol group.

“Among participants of the polyphenols group, an inverse correlation was observed between the consumption of polyphenols estimated by the [food frequency questionnaire] with PGE2 levels at the end of the study. This finding had not yet been previously described in the literature and reinforces the hypothesis of the present study regarding the action of polyphenols in reducing PGE2 levels,” wrote the researchers.

“The liver is the main organ involved in the metabolism of polyphenols, and metabolites are secreted in bile and urine. Excretion of polyphenols in participants of the [polyphenol group] was significantly higher than in the [control group], confirming the effective ingestion of capsules and absorption of compounds, which can vary depending on the amount ingested, the chemical structure of the substance and the intestinal flora of the subjects.”

Childhood diet and exercise creates healthier, less anxious adults

University of California Riverside, April 9, 2021

Exercise and a healthy diet in childhood leads to adults with bigger brains and lower levels of anxiety, according to new UC Riverside research in mice. 

Though diet and exercise are consistently recommended as ways to promote health, this study is the first to examine the long-lasting, combined effects of both factors when they are experienced early in life.

"Any time you go to the doctor with concerns about your weight, almost without fail, they recommend you exercise and eat less," said study lead and UCR physiology doctoral student Marcell Cadney. "That's why it's surprising most studies only look at diet or exercise separately. In this study, we wanted to include both."

The researchers determined that early-life exercise generally reduced anxious behaviors in adults. It also led to an increase in adult muscle and brain mass. When fed "Western" style diets high in fat and sugar, the mice not only became fatter, but also grew into adults that preferred unhealthy foods.

These findings have recently been published in the journal Physiology and Behavior. To obtain them, the researchers divided the young mice into four groups -- those with access to exercise, those without access, those fed a standard, healthy diet and those who ate a Western diet. 

Mice started on their diets immediately after weaning, and continued on them for three weeks, until they reached sexual maturity. After an additional eight weeks of "washout," during which all mice were housed without wheels and on the healthy diet, the researchers did behavioral analysis, measured aerobic capacity, and levels of several different hormones.

One of those they measured, leptin, is produced by fat cells. It helps control body weight by increasing energy expenditure and signaling that less food is required. Early-life exercise increased adult leptin levels as well as fat mass in adult mice, regardless of the diet they ate.

Previously, the research team found that eating too much fat and sugar as a child can alter the microbiome for life, even if they later eat healthier. Going forward, the team plans to investigate whether fat or sugar is more responsible for the negative effects they measured in Western-diet-fed mice.

Together, both studies offer critical opportunities for health interventions in childhood habits. 

"Our findings may be relevant for understanding the potential effects of activity reductions and dietary changes associated with obesity," said UCR evolutionary physiologist Theodore Garland. 

In other words, getting a jump start on health in the early years of life is extremely important, and interventions may be even more critical in the wake of the pandemic. 

"During the COVID-19 lockdowns, particularly in the early months, kids got very little exercise. For many without access to a park or a backyard, school was their only source of physical activity," Cadney said. "It is important we find solutions for these kids, possibly including extra attention as they grow into adults." 

Given that exercise was also shown to reduce adult anxiety, Cadney believes children who face these challenges may face unique physical and mental health issues as they become adults in the coming decade.
