Choose a hearing aid that works for you

People with impaired hearing may be able to follow conversations fairly well, but with a lot of effort. Even if someone can still make do without a hearing aid, using one can make life a lot easier. High-tech miniaturized hearing aids are marketed aggressively. These devices try to adjust their volume to meet different conditions, but may fail to do so consistently. This leads to frustration as well as great expense, since high-tech hearing aids cost a lot more. A better option for some people may be a larger behind-the-ear model that supplies more volume and the ability to more easily control it.

A bioengineered collagen patch allows the heart to do something it can't do by itself: regenerate heart muscle killed by a heart attack. It works in mouse studies, and may in the future be used to deliver stem cells or medicines directly to the heart. (Locked) More »

Pacemaker safe after age 90

Age alone should not be a barrier to pacemaker implantation—even for some people over age 90, according to a Harvard-based study. It’s one of a few studies to guide clinical decisions for people in their 90s—a population that will quadruple to eight million Americans by 2050. The data suggest that a person’s health status and other underlying conditions are more important for determining the success of pacemaker implantation than age itself. (Locked) More »

Surgery called partial meniscectomy has been the traditional way to correct a torn meniscus in people with osteoarthritis. However, new research suggests people with this condition may be able to try physical therapy before resorting to surgery. (Locked) More »
