Zinc found to play an important role in lung fibrosis
Cedars-Sinai Medical Center, June 8, 2022
Investigators from the Women’s Guild Lung Institute at Cedars-Sinai have discovered that zinc, a common mineral, may reverse lung damage and improve survival for patients with a deadly age-related condition known as idiopathic pulmonary fibrosis (IPF).”This study has the potential to be a game changer,” said Paul Noble, MD, chair of the Department of Medicine. “We identified a root cause of IPF-related lung damage and a potential therapeutic target that might restore the lungs’ ability to heal themselves.”
Idiopathic pulmonary fibrosis, or IPF, affects 100,000 people in the U.S. and has no known cause. The condition, which leads to scarring of the lungs, called fibrosis, and progressive breathing difficulty, has no cure, and most patients die or require a lung transplant within three to five years of diagnosis. The incidence of IPF rises dramatically with age and affects men more often than women.
Do optimists live longer?
Harvard School of Public Health, June 8, 2022
In a study published in the Journal of the American Geriatrics Society that included a racially diverse group of 159,255 women, higher levels of optimism were associated with longer lifespans and a greater likelihood of living past 90 years of age. Investigators found that the link between optimism and longevity was evident across racial and ethnic groups, and that lifestyle factors accounted for nearly one-quarter of the optimism-lifespan association.
Sweet cherry anthocyanins support liver health… for rats at least
Zhei-Jang University (China), June 1, 2022
Anthocyanins from sweet cherries may protect against diet-induced liver steatosis, or excessive amounts of fat in the liver’s tissue, says a new study with rats.
The study, published in the journal Nutrition, built upon the abundant existing literature on the beneficial role anthocyanins have as an antioxidative, anti-inflammatory, and anti-hyperlipidemic component. Specifically, the cyanidin-3-glucoside variant “[has] been reported to ameliorate hepatic steatosis and adipose inflammation,” the researchers wrote. The condition known as liver steatosis is a common non-alcoholic fatty liver disease usually treated with drugs, but according to the researchers, some drug used for treatment “are usually accompanied by some adverse effect.” For 15 weeks, the researchers investigated the effects of sweet cherry anthocyanin supplementation have on alleviating high-fat diet-induced liver steatosis in rodents to explore the possibility of a none-drug treatment for the liver condition. According to the researchers, the results demonstrated how sweet cherry anthocyanins may be developed into a supplement to “protect from high-fat diet-induced hepatic steatosis in mice,”leading to a suggested potential for the anthocyanin’s application in the “treatment of hepatic steatosis and other obesity related metabolic disorders.”
Bad dreams could be early warning of Parkinson’s disease
University of Birmingham, June 8, 2022
Older adults who start to experience bad dreams or nightmares could be exhibiting the earliest signs of Parkinson’s disease, say researchers at the University of Birmingham. A new study, published in eClinicalMedicine, showed that in a cohort of older men, individuals experiencing frequent bad dreams were twice as likely to be later diagnosed with Parkinson’s as those who did not.Previous studies have shown that people with Parkinson’s disease experience nightmares and bad dreams more frequently than adults in the general population, but using nightmares as a risk indicator for Parkinson’s has not previously been considered.”While we need to carry out further research in this area, identifying the significance of bad dreams and nightmares could indicate that individuals who experience changes to their dreams in older age—without any obvious trigger—should seek medical advice.” The team used data from a large cohort study from the U.S., which contained data over a period of 12 years from 3818 older men living independently. Participants reporting bad dreams at least once per week were then followed up at the end of the study to see whether they were more likely to be diagnosed with Parkinson’s disease.
Beetroot boosts sporting performance in athletes
University of South Australia, June 8, 2022
Evaluating the performance effects of foods that are thought to have a beneficial effect on aerobic performance, researchers found that beetroot, grapes, sour cherries, and pine bark extract, which contribute to nitric oxide availability in the body, boost endurance exercise performance. Assessing data from 118 studies involving 1,872 participants from 25 different countries, the meta-analysis evaluated the effect of consuming nitrate-rich foods (typically green leafy vegetables), foods that contain polyphenols (such as berries, cherries and cocoa), and L-Citrulline (found in watermelon) on exercise endurance performance. The study, published in the Journal of the International Society of Sports Nutrition, found that the nitrate levels contained in beetroot, which have been shown to boost blood flow and increase the delivery of nutrients and oxygen to muscles during exercise, helped athletes perform better more quickly.
