Turmeric may help ease the pain of a dodgy knee

University of Tasmania, September 11, 2020

An extract of Curcuma longa (CL), commonly known as turmeric, was found to be more effective than placebo for reducing knee pain in patients with knee osteoarthritis. However, CL did not affect structural aspects of knee osteoarthritis, such as swelling or cartilage composition assessed using MRI. Findings from a randomized, double-blind, placebo-controlled trial are published in Annals of Internal Medicine.

Despite its large disease burden, no approved disease-modifying drugs currently are available to treat osteoarthritis. Common treatments, such as acetaminophen and nonsteroidal anti-inflammatory drugs have only mild to moderate effects and are associated with adverse events. As such, an urgent need exists for safer and more effective drugs to treat osteoarthritis.

Researchers from the University of Tasmania, Australia randomly assigned 70 participants with symptomatic knee osteoarthritis and ultrasound evidence of effusion (swelling inside the knee joint) to receive either two capsules per day of CL (n = 36) or matched placebo (n = 34) for 12 weeks to determine the efficacy CL for reducing knee symptoms and joint swelling. Changes in pain and knee effusion-synovitis volume were assessed by standardized questionnaire and MRI, respectively, over 12 weeks. The researchers also looked for changes in cartilage composition, pain medication usage, quality of life, physical performance measures, and adverse events. 

After 12 weeks, they found that patients taking the turmeric supplements reported less pain than those in the placebo group with no adverse events. Besides, participants in the turmeric group consumed fewer pain medications compared to the participants in the placebo group. There was no difference in the structural aspects of knee osteoarthritis between the groups. Due to the modest effect of the turmeric extracts on knee pain, small sample size of the study, short-duration of follow-up and the single research center, the researchers suggest that multicenter trials with larger sample sizes and long duration of follow-up are needed to assess the clinical significance of their findings.

 

Pine bark supplements fight the harmful effects of oxidative stress after exercise: Research

University of Louisiana, September 15, 2020

Researchers from the University of Louisiana at Lafayette said that taking pine bark supplements led to lower levels of malonaldehyde (MDA), a toxic compound that serves as a biomarker for oxidative stress. This effect was seen 48 hours after exercise among individuals who took the supplements for at least two weeks.

The researchers noted that high physical activity often spurs higher levels of oxidative stress. But by taking pine bark supplements, individuals can benefit from an enhanced healing process.

“[Maritime] pine extract as compared to placebo was effective at affording protection from oxidative stress post-exercise,” wrote the researchers.

Pine bark extract protects against oxidative stress

Pine bark extract is an herbal extract that comes from the tree Pinus pinaster, or maritime pine. It grows abundantly in France, where its medicinal uses date back to the 14th century. French sailors used pine bark to combat scurvy, a condition caused by vitamin C deficiency, as they sailed from France to the New World.

Aside from being rich in vitamin C, pine bark extract is also packed with phytochemicals – natural plant compounds that contribute to the color, taste and smell of vegetables. The phytochemicals found in pine bark supplements include procyanidins and flavonoids, both of which lower inflammation and protect from oxidative stress. Previous research also linked pine bark extract to a host of health benefits such as boosting brain function, balancing blood sugar levels and improving blood flow.

In the study, the researchers looked at the effects of pine bark supplements on 20 healthy men. They were randomly assigned to either 200 mg of the extract or a placebo and took these for 14 days prior to the first exercise trial and for 2?days post-exercise. After a seven-day washout period, the men were asked to take the other medication.

Results showed that MDA levels significantly decreased among the pine bark group compared to the placebo group. The placebo group also displayed significant increases in MDA levels before and 48 hours after the exercise.

Given these findings, the researchers recommended further research to evaluate the effects of pine bark extract among individuals who practice intense training. Furthermore, they see great potential in pine bark extract for helping treat metabolic syndrome, a group of diseases that are influenced by oxidative stress.

 

Researchers use soy to improve bone cancer treatment

Washington State University, September 15, 2020

 

Researchers in recent years have demonstrated the health benefits of soy, linking its consumption to reduced risk of cardiovascular disease, obesity, cancer and improved bone health. 

Now, WSU researchers are hoping to use the health benefits of the popular legume to improve post-operative treatment of bone cancer. 

Reporting in the journal, Acta Biomaterialia, graduate student Naboneeta Sarkar and Professor Susmita Bose in WSU's School of Mechanical and Materials Engineering showed that the slow release of soy-based chemical compounds from a 3D-printed bone-like scaffold resulted in a reduction in bone cancer cells while building up healthy cells and reducing harmful inflammation. 

"There is not much research in this area of natural medicinal compounds in biomedical devices," Bose said. "Using these natural medicines, one can make a difference to human health with very minimal or no side effects, although a critical issue remains composition control." 

Although rare, osteosarcoma occurs most often in children and young adults. Despite medical advances, patients with osteosarcoma and metastatic bone cancer experience a high rate of recurrence, and osteosarcoma is second leading cause of cancer death in children. 

Treatment involves surgery to remove the tumor as well as pre- and post-operative chemotherapy. Large areas of bone need to be removed and repaired, and patients often experience a significant amount of inflammation during bone reconstruction, which slows healing. High doses of chemotherapy before and after surgery can also have harmful side effects.

Researchers would like to develop gentler treatment options, especially after surgery when patients are trying to recover from bone damage at the same time that they are taking harsh drugs to suppress tumor growth. Bose's team has been studying bone tissue engineering as an alternative strategy to repair the bone, using materials science principles and advanced manufacturing techniques to develop effective biomedical devices. 

As part of this study, the researchers used 3D printing to make patient-specific, bone-like scaffolds that included three soy compounds and then slowly released the compounds into samples containing bone cancer as well as healthy bone cells. Soybeans contain isoflavones, plant-derived estrogens that have been shown to impede cancer cell growth for many types of cancer without being toxic to normal cells. Isoflavones have also been shown to improve bone health and possibly prevent osteoporosis. 

One of the soybean compounds caused a 90% reduction in bone cancer cell viability in their samples after 11 days. Two other soy compounds, meanwhile, significantly improved the growth of healthy bone cells. Furthermore, using the soy compounds in animal models also reduced inflammation, which could benefit bone health as well as overall recovery. 

"These results advance our understanding in providing therapeutic approaches in using synthetic bone grafts as a drug delivery vehicle," Bose said. 

The researchers are continuing the unique area of research, studying the specific pathways of the genetic expression of natural compounds and the benefits of integrating them in biomedical technology. More detailed long-term studies are needed, using animal research as well as other malignant cells, she said.

 

 

Broccoli extract found to significantly improve autism symptoms; sulforaphane molecule is powerful natural medicine

Mass General Hospital for Children, September 14, 2020

A powerful anti-cancer nutrient found naturally in cruciferous vegetables such as broccoli and cauliflower could help significantly improve health outcomes in autistic men and boys. Research published in the journal The Proceedings of the National Academy of Sciences reveals that sulforaphane, an antioxidant compound, is capable of reversing many of the most common symptoms associated with autism spectrum disorders (ASD).

Although the U.S. Centers for Disease Control and Prevention (CDC) claims that there are no medications currently on the market that can treat or cure ASD, a placebo-controlled, randomized, double-blind pilot study suggests otherwise. Present most richly in broccoli sprouts, sulforaphane has been shown to help drastically improve social interactions and verbal communication in ASD-diagnosed men and boys as well as reduce hyperactivity, irritability and other ASD symptoms.

Conducted on 44 males aged 13 to 27, the study found that after 18 weeks of consuming sulforaphane-rich broccoli sprout extract, more than half of the men saw significant health improvements. Behavioral abnormalities also decreased significantly as a result of the treatment, as did lipid peroxidation and neuroinflammation. These same men also saw improvements in antioxidant capacity, glutathione synthesis, mitrochondrial function and oxidative phosphorylation.

"Sulforaphane, which showed negligible toxicity, was selected because it upregulates genes that protect aerobic cells against oxidative stress, inflammation, and DNA-damage, all of which are prominent and possibly mechanistic characteristics of ASD," the authors wrote.

Sulforaphane in broccoli sprouts regulates cellular health, energy production and detoxification

Depending on their individual weights, the men and boys were assigned to take either 232 mg (for those who weighed 100 pounds or less), 464 mg (101 to 199 pounds), or 696 mg (more than 200 pounds) of sulforaphane-rich broccoli extract daily. Such amounts are difficult to obtain from eating broccoli sprouts whole, but many supplement manufacturers offer capsules containing concentrated extract levels in this range or even higher.

This is good news for parents who are trying to help their autistic children achieve a better quality of life naturally. Sulphorane is an antioxidant nutrient with no negative side effects, meaning it can only help an ASD-afflicted child. Likewise, whole broccoli sprouts are a "superfood," not a drug, so parents do not have to worry that it will harm their children in any way.

As an added benefit, sulforaphane might also help ameliorate a number of other genetic disorders by activating the body's "stress proteome." The stress proteome is responsible for regulating processes such as glutathione synthesis, mitochondrial function (cellular health), and neurological inflammation.

When ASD patients stopped taking sulforaphane, their symptoms returned

In order for sulforaphane to work, however, ASD patients need to continue taking it. At the 22-week reassessment, which took place one month after study participants ceased taking the broccoli sprout extract, most (but not all) of their improvements had waned or disappeared. The researchers involved say this change only reinforces their finding that sulforaphane was directly responsible for the positive improvements observed throughout the study.

"When we broke the code that revealed who was receiving sulforaphane and who got the placebo, the results weren't surprising to us, since the improvements were so noticeable," stated Dr. Andrew Zimmerman, M.D., one of the study's authors and a physician at MassGeneral Hospital for Children (MGHfC).

"The improvements seen on the Social Responsiveness Scale were particularly remarkable, and I've been told this is the first time that any statistically significant improvement on the SRS has been seen for a drug study in autism spectrum disorder," he added, noting that the consensus among the research team was that sulforaphane likely activates the Nrf2 pathway, reducing inflammation in the brain and promoting increased antioxidant protection.

 

 

 

Exercise's Surprising Potential To Treat People With Multiple Chronic Conditions

University of Southern Denmark, September 11, 2020

 

Hundreds of millions of people of all ages worldwide live with two or more chronic conditions – commonly defined as multimorbidity. Those living with it are found to have poorer physical and mental health, higher risk of being admitted to hospital, and higher risk of dying prematurely compared to people with only one chronic condition.

Given that the number of people living with multimorbidity is only expected to rise in the future, finding better treatments is considered the next major health priority. But despite multimorbidity being a leading cause of disability, research on treatments are still in its infancy. Few studies have investigated treatment options – and unfortunately the results of these studies most often offer negligible improvements.

People with multimorbidity want treatments that will improve their physical, mental, emotional, and social health. Our research found that exercise may actually be a surprising treatment for those living with multimorbidity, and offer many of these improvements patients want.

Currently, multimorbidity is managed by treating each chronic conditions separately using available medicines. However, this might not reduce symptoms sufficiently, and can have many adverse health effects. Many people consult several health care providers and also end up taking multiple drugs (often at least one for each condition) which carries a risk of adverse events and can be inconvenient and unsatisfactory for patients.

Exercise as medicine

Research has shown exercise is an effective treatment for 26 chronic conditions, including osteoarthritis, depression and type 2 diabetes. Research also shows exercise could potentially prevent 35 chronic conditions from developing.

Thanks to its overall effects on health (such as lowering blood pressureimproving joint health and cognitive function, exercise therapy can benefit a range of chronic conditions. It also has a lower risk of negative side effects compared to pharmacological treatments. At the same time, exercise requires physical effort, and like pharmacological treatments, the effects will diminish if you stop exercising.

But could exercise therapy benefit people with multiple chronic conditions as well? This is what our recent review aimed to investigate.

We assessed the effect of exercise therapy on the physical and mental health of people with at least two of the following chronic conditions: osteoarthritis of the knee or hip, hypertension, type 2 diabetes, depression, heart failure, ischemic heart disease, and chronic obstructive pulmonary disease. We found 23 studies that looked at adults aged 50 to 80 years old.

The exercise therapy interventions used in the studies were at least partially supervised by a physiotherapist or an exercise physiologist. Most lasted 12 weeks on average and exercise was performed two to three times a week, starting from low intensity and progressing to moderate to high intensity. The exercise therapies included were aquatic exercise, strength training, aerobic training and tai chi.

Our review showed exercise therapy improved quality of life and reduced anxiety and depression symptoms. The benefits were higher in younger patients and patients who had higher depression symptoms before starting exercise therapy. This highlights that people with severe depression – often considered ineligible for exercise due to their depression severity – may benefit highly from exercise therapy.

Patients who participated in exercise therapy were also able to walk longer. Those taking part walked on average 43 metres more than those not taking part in the exercise interventions, over six minutes. This improvement appears to be important for the patient and it reduced their disability.

Exercise therapy also didn’t increase risk of non-serious side effects, such as knee, arm, or back pain, or falls and fatigue. What’s more, it reduced the risk of hospitalisation, pneumonia, and extreme fatigue.

As such, exercise could be a safe and effective therapy instead of increasing drug prescription in people with multiple chronic conditions. The benefits were similar across all the combinations of chronic conditions included in our study. However these findings need to be confirmed in future trials to have a more definitive answer.

Together with patients and healthcare professionals, we are developing and testing an exercise therapy and self-management programme in the MOBILIZE project. This trial will help us understand whether personalised exercise therapy and self-management is effective in managing and treating multimorbidity.

In the meantime, people with multimorbidity can improve mental and physical health by exercising two to three times a week. Aerobic workouts, strength training or a combination of the two can promote similar health benefits, regardless of the conditions a person live with. However, it’s important that the exercise therapy sessions are supervised and that the intensity of the session progresses based on patient capabilities.

 

Plant-based diets found to relieve symptoms of rheumatoid arthritis

George Washington University, September 14, 2020

 

In a major breakthrough, a team of researchers from the George Washington University School of Medicine and Health Sciences and the non-profit health organization Physicians Committee for Responsible Medicine (PCRM) looked at recent studies that assessed the impact of diet on the risk of rheumatoid arthritis.

The group found that certain foods, such as red meat, milk and milk products, could exacerbate the condition. In contrast, diets rich in plant-based foods like fruits, grains and legumes help reduce pain and inflammation in rheumatoid arthritis patients.

In all, these findings suggest that a simple menu change could help patients better manage their disease, said co-author and PCRM clinical research director Hana Kahleova. Sticking to a plant-based diet could also keep the disease in remission for long periods. Their findings appeared online in the journal Frontiers in Nutrition.

Plant-based diets can benefit rheumatoid arthritis patients

Numerous studies indicate that plant-based diets could help decrease the risk of chronic autoimmune conditions like rheumatoid arthritis. In patients, adopting a plant-based diet could help in better management of the disease for the long-term.

There are a number of possible mechanisms behind these beneficial effects. For instance, results of randomized clinical trials (RCT) indicate that a plant-based diet could reduce total cholesterol and induce weight loss better than conventional calorie-restricted diets.

Having high cholesterol and being obese could lead to the onset of rheumatoid arthritis or exacerbate joint pain and inflammation in patients. Therefore, these findings suggest that a plant-based diet decreases the risk and eases the effects of rheumatoid arthritis thanks to its influence on weight and total cholesterol.

Furthermore, several observational studies found strong and consistent evidence that a plant-based diet can reduce inflammation linked to rheumatoid arthritis. In contrast, semi-vegetarian or omnivorous diets that still contained meat and animal products triggered inflammation in patients.

In particular, one RCT found that a gluten-free vegan diet reduced the amount of a pro-inflammatory antibody, called immunoglobulin G (IgG), in rheumatoid arthritis patients. Patients typically have higher than appropriate amounts of IgG in their blood and lymph fluid.

Moreover, another RCT found that a three-month Mediterranean dietary intervention improved rheumatoid arthritis symptoms. A Mediterranean diet is rich in monounsaturated fats that protect against inflammation and oxidative stress. Copious amounts of these fats can be found in plant-based foods like nuts and avocados.

In addition, the researchers found that the state of one’s gut health, which depends on diet and nutrition, could also influence the onset and progression of rheumatoid arthritis. For instance, a permeable intestinal barrier, a marker of poor gut health, allows for bacteria and other microbes to enter the bloodstream.

These harmful agents could then trigger inflammation and joint pain in rheumatoid arthritis patients. Research shows that a plant-based diet modulates the gut microbiome for better gut health. In turn, this leads to less intestinal inflammation, which some studies suggest is connected to joint inflammation.

The researchers attribute these effects to the fibers in many plant-based foods. Fiber feeds the beneficial bacteria in the gut, thus making it less prone to infection and inflammation. Enzymes and amino acids in plant-based foods also increase bacterial diversity in the gut, which rheumatoid arthritis patients often lack.

Taken together, these studies provide empirical evidence that a plant-based diet comprised of fruits, vegetables, grains and legumes could be incredibly beneficial for people with rheumatoid arthritis.

 

 

Researchers Report Recent Findings that Garlic Improves Visual Memory and Attention

University of Dhaka (Bangladesh), September 14, 2020

Researchers from University of Dhaka Report Recent Findings in Complementary and Alternative Medicine that  "Studies have shown that Allium sativum L.  or garlic protects amyloid-beta peptide-induced apoptosis, prevents oxidative insults to neurons and synapses, and thus prevent Alzheimer's disease progression in experimental animals. However, there is no experimental evidence in human regarding its putative role in memory and cognition."

The news correspondents obtained a quote from the research from the University of Dhaka, "We have studied the effect of garlic consumption by healthy human volunteers on visual memory, verbal memory, attention, and executive function in comparison to control subjects taking placebo. The study was conducted over five weeks and twenty volunteers of both genders were recruited and divided randomly into two groups: A Garlic and B (placebo). Both groups participated in the 6 computerized neuropsychological tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) twice: at the beginning and after five weeks of the study. We found statistically significant difference (p < 0.05) in several parameters of visual memory and attention due to AS ingestion. We also found statistically nonsignificant (p > 0.05) beneficial effects on verbal memory and executive function within a short period of time among the volunteers."

According to the news reporters, the research concluded: "Study for a longer period of time with patients suffering from neuro degenerative diseases might yield more relevant results regarding the potential therapeutic role of garlic."

 

 

 

Why You Should Eat Two Apples a Day

Green Med Info, September 12th 2020 

 

A 2020 study points to apples' ability to mediate significant gut microbial metabolic activity. All it takes: two apples a day. In light of the increasing link between gut microbiota and human wellness, this new association is worth exploring and further vouches for this fruit's superfood and super healer status

The old saying that eating an apple a day will keep the doctor away may have some scientific basis after all, as scientific literature is packed with findings that vouch for this fruit's healthful benefits.

Showing that the saying above goes beyond folk medicine fantasy, a study found that eating one apple a day for four weeks translated to lower blood levels of oxidized low-density lipoprotein//beta2-glycoprotein I complex, which may contribute to atherosclerosis, by 40% among healthy, middle-aged individuals.[i]

Apple consumption has also been the subject of a few studies on reducing cancer risk, including liver cancerbreast cancer and esophageal cancer.[ii] A study published in February 2020 points to apples' ability to mediate significant gut microbial metabolic activity. All it takes: two apples a day.

Study Findings

Apples are a frequently consumed fruit and a reliable source of polyphenols and fiber, an important mediator for their health-protective effects.[iii]

Validated biomarkers of food intake (BFIs) have recently been suggested as a good tool for assessing adherence to dietary guidelines. New biomarkers have[iv] surfaced in recent decades from metabolic profiling studies for different foods, yet the number of comprehensively validated BFIs remains limited.

BFIs offer an accurate measure of intake, independent of the memory and sincerity of the subjects as well as of their knowledge about the consumed foods.[v] They overcome food intake measurement with inherent limitations, such as self-reported dietary intake questionnaires, as they objectively assess food intake without biased self-reported assessment.

The researchers sought to identify biomarkers of long-term apple consumption, exploring how the fruit affects human plasma and urine metabolite profiles. In their randomized, controlled, crossover intervention study, they recruited 40 mildly hypercholesterolemiapatients and had them consume two whole apples or a sugar and energy-matched beverage daily for eight weeks.

At the end of the trial, they found 61 urine and nine plasma metabolites that were statistically significant after the whole apple intake compared to the control beverage. The metabolites included several polyphenols that could serve as BFIs.

Interestingly, the study allowed the group to explore correlations between metabolites significantly modulated by the dietary intervention and fecal microbiota species at genus level -- specifically interactions shared by Granulicatella genus and phenyl-acetic acid metabolites.

"[T]he identification of polyphenol microbial metabolites suggests that apple consumption mediates significant gut microbial metabolic activity which should be further explored," they wrote.[vi]

Gut Health Affects Your Whole Body

The link between the gut microbiota and human wellness is being increasingly recognized, where it is now well-established that healthy gut flora is a key part of your overall health.[vii]

Previous studies corroborate that the richness of the human gut microbiome correlates with metabolic markers. In a study on 123 non-obese and 169 obese Danish individuals, a group of scientists found two distinct groups displaying a difference in the number of gut microbial genes and thus the richness of gut bacteria in the two groups.[viii]

Individuals with a low bacterial richness had more marked overall adiposity and insulin resistance, for instance, compared with high bacterial richness subjects. The obese subjects among the lower bacterial richness group also tended to gain more weight over time.

A series of largely pre-clinical observations showed, too, that changes in brain-gut-microbiome communication may be involved in the pathogenesis and pathophysiology of irritable bowel syndromeobesity and several psychiatric and neurologic disorders.[ix]

Additional Apple Benefits

More benefits of apple intake are coming out of the medical literature, confirming its superfood and super healer status that shouldn't be missed out on.

These benefits include addressing common issues such as aging (reduced rate), allergies, alopecia or hair loss, diarrhea, insulin resistance, radiation-induced illness, and Staphylococcal infection. In the area of cancer treatment, apples have been found to both prevent and suppress mammary cancers in the animal model, while carotenoids extracted from the fruit have been found to inhibit drug-resistant cancer cell line proliferation.[x]
