TUESDAY, May 11, 2021 (HealthDay News) -- It may be possible to treat the thinking problems that result from repeated hits to the head, a new laboratory study suggests.The new experiments with mice are the first to offer a molecular analysis of what happens in the brain after repetitive but mild blows to the head, said researcher Mark Burns. He is head of the Laboratory for Brain Injury and Dementia at Georgetown University, in Washington, D.C."Most research in this area has been in mouse models with more severe brain injury, or in human brains with chronic traumatic encephalopathy (CTE)," Burns said in a university news release. "This means that we have been focusing only on how CTE pathology develops. Our goal was to understand how the brain changes in response to the low-level head...

TUESDAY, May 11, 2021 (HealthDay News) -- Serious cases of "long-haul COVID-19" are rare in patients who were not hospitalized after their infection, but these patients still report more doctor or health care visits after recovery,. Danish researchers report.The new six-month study found that COVID patients who were not hospitalized had small increased risks of blood clots and breathing difficulties. They were also more likely to start medicines for breathing difficulties and migraines than those who weren't infected.These former COVID patients visited their primary care provider and outpatient hospital care more often than people who weren't infected, researchers said.For the study, published May 10 in the journal The Lancet Infectious Diseases, the researchers compared data from...

TUESDAY, May 11, 2021 (HealthDay News) -- Steaks and burgers could be killing thousands of Americans each year, but in a way most people wouldn't expect -- via air pollution.That's the conclusion of a new study estimating that airborne particles generated by food production kill nearly 16,000 Americans each year. Pollution related to animal products -- most notably beef -- accounts for 80% of those deaths."What we eat affects not only our own health, but the health of others," said researcher Jason Hill, a professor of bioproducts and biosystems engineering at the University of Minnesota in St. Paul.Farming generates pollutants in numerous ways, but Hill's team focused specifically on its role in fine-particle pollution -- tiny substances suspended in the air that can be inhaled deeply...

TUESDAY, May 11, 2021 (HealthDay News) -- Could there be a way to tell years in advance which girls are more likely to develop eating disorders?New research from Denmark suggests that childhood body mass index (BMI) may offer important clues. BMI is an estimate of body fat based on height and weight.The new research linked lower BMI as early as age 7 with a higher risk of anorexia, an eating disorder in which people severely restrict calorie intake. It also found an association between higher BMI and being overweight with an increased risk of bulimia, a binge-eating disorder in which episodes of extreme eating are followed by forced vomiting or fasting."There are many factors that influence the development of eating disorders," said lead author Dr. Britt Wang Jensen, of Bispebjerg and...
