Some benefits of Exercise stem from the Immune System, suggests new study

The connection between exercise and inflammation has captivated the imagination of researchers ever since an early 20th-century study showed a spike of white cells in the blood of Boston marathon runners following the race.

Now, a new Harvard Medical School study published in Science Immunology may offer a molecular explanation behind this century-old observation.

The study, in mice, suggests that the beneficial effects of exercise may be driven, at least partly, by the immune system. It shows that muscle inflammation caused by exertion mobilizes inflammation-countering T cells, or Tregs, which enhance the muscles’ ability to use energy as fuel and improve overall exercise endurance.

Mind-Body Link Exposed: Unraveling the Physical Costs of Mental Disorders

Psychiatric patients almost twice as likely to have multiple physical ailments – new study.

A new study, conducted by Anglia Ruskin University (ARU) in collaboration with the University of Cambridge’s Biomedical Research Centre, has revealed significant findings about the physical health of psychiatric patients. This extensive analysis incorporated data from 19 different studies, involving 194,123 psychiatric patients globally, and compared them to 7,660,590 individuals in control groups.

Findings on Multimorbidity.

Scientists invent toothpaste that can treat peanut allergies

In experiments conducted on the toothpaste no major side effects were reported.

Peanuts are one of the most common food allergens, and peanut allergies tend to persist into adulthood more frequently than allergies to other foods. Peanut allergies are common, particularly in Western countries. The prevalence of peanut allergies appears to be increasing, and it is estimated that about 2.9 percent of the population in the United States suffers from the condition.

Adult-made neurons mature longer, have unique functions

The challenge of measuring adult neurogenesis is difficult, but it’s not impossible. A big part of the solution is knowing what to measure and where. While this new study was performed on rats—and therefore may be a poor predictor of what we’ll see in humans—it can direct future research by showing neuroscientists where to look and what to look for.

And unlike the hard problem of consciousness, unraveling the mysteries of adult neurogenesis may have clinical applications. Better the lifecycle of neurons may reveal how neurological disorders such as Parkinson’s and Alzheimer’s disease emerge. There’s even research linking disorders such as depression and anxiety to neurogenesis activity.

This knowledge may lead to new treatments, but if not, it could also reveal a better understanding of how our lifestyles and environments support brain health and regeneration throughout human life.

Supercharging the gut’s immunity with butyrate

Researchers at the University of Oxford, UK have found that butyrate, a short-chain fatty acid produced by gut bacteria, can boost the antimicrobial activity of immune cells in the gut, possibly helping them better fend off bacterial infections and improve immune health.

The study, which exposed human monocytes and macrophages (immune cells) to bacterial infections to simulate real-world scenarios in the lab, backs up ongoing research into the benefits of butyrate as a therapeutic component to combat conditions—from food allergies to inflammatory bowel disease (IBD) and support immune system function.

Cannabis Use Connected with Potential Long-Term Cardiology Issues

Two recent studies due to be presented as posters at the American Heart Association (AHA) Scientific Sessions 2023 between November 11–13 examine how frequent cannabis use could potentially lead to increased chances of cardiology issues, including heart attack, stroke, or heart failure. These studies were conducted by an international team of researchers and holds the potential to help scientists, medical professionals, and the public better understand the long-term health risks associated with cannabis use, specifically pertaining to cardiovascular concerns.

For the first study, which was conducted by the All of Us Research Program, researchers enlisted 156,999 participants who had not experienced heart failure at the time of the study’s enrollment to take part in a survey-based study to evaluate their cannabis use habits and conduct a follow-up survey 45 months later. The results indicated that heart failure emerged with 2,958 (1.88 percent) of the participants during the 48-month study period along with a 34 percent increased risk of emerging heart failure for participants were reported daily cannabis use compared to participants who didn’t use cannabis.

“Our results should encourage more researchers to study the use of marijuana to better understand its health implications, especially on cardiovascular risk,” said Dr. Yakubu Bene-Alhasan, who is a resident physician at Medstar Health and lead author of the study. “We want to provide the population with high-quality information on marijuana use and to help inform policy decisions at the state level, to educate patients and to guide health care professionals.”

New Hope to Treat and Reverse Osteoarthritis

Current osteoarthritis treatment manages symptoms rather than addressing the underlying disease, but a new University of Adelaide study has shown the condition may be treatable and reversible.

Osteoarthritis is the degeneration of cartilage and other tissues in joints and is the most common form of arthritis in Australia, with one in five people over the age of 45 having the condition.

It is a long-term and progressive condition which affects people’s mobility and has historically had no cure. Its treatment cost the Australian health system an estimated $3.9 billion in 2019–20.
