Summertime is time for sun, swimming and sports. Here are some tips from John Marcucci, M.D., medical director of emergency medicine on the medical staff at Baylor Regional Medical Center at Plano, on how to safely enjoy the season.
Although a number of studies have suggested that regular exercise reduces inflammation ? a condition that is predictive of cardiovascular and other diseases, such as diabetes ? it is still not clear whether there is a definitive link. And if such a link exists, the nature of the relationship is by no means fully understood.
A new study appearing in the Journal of the American Geriatrics Society compares the efficacy of three programs designed for reducing falls and improving quality-of-life among the elderly; education, home safety assessment and modification (HSAM) and exercise training. The study also examines the secondary effects of these programs on functional balance, daily activity, fear of falling and depression level, finding that exercise training yields the most significant improvements.
In the battle of the bulge, dieters often seek reinforcements ? such as a doctor?s prescription, counseling by a mental health professional, suggestions from a trainer or membership in a weight-loss support group. However, some people might be more reluctant to look for outside assistance than others.
UK men and women say reducing their risk of cancer is last on a list of reasons to exercise, according to a national survey by Cancer Research UK and Cannons.
Current PET-CT scanners with standard commercial software designed to provide images of the heart are falsely indicating coronary artery disease in as many as 40 percent of patients, according to a study published today on the cover page of the Journal of Nuclear Medicine.
Griffith University has been working with Queensland Health and the University of Southern Queensland (USQ) to reduce the cost of sleep disorders.
During vigorous exercise, heart muscle cells take a beating. In fact, some of those cells rupture, and if not for a repair process capable of resealing cell membranes, those cells would die and cause heart damage (cardiomyopathy).
In the normal heart, the cycling of intracellular calcium in cardiac muscle cells is critical to the heart?s mechanical contraction and relaxation. Mutations in calcium-handling proteins in the heart have been linked to exercise-induced sudden cardiac death.
Kevin Campell and fellow University of Iowa researchers have shown that a protein known as dysferlin plays a critical role in repairing the plasma membranes of cardiac muscle cells that are torn as a result of strain-induced injury.
