In the largest study of its kind to date, researchers have found that exercise is safe for people with heart failure, improves quality of life — and may even reduce the risk of death or hospitalization. This is good news for the 5 million Americans whose hearts cannot pump enough blood through the body due to coronary heart disease, diabetes, high blood pressure, or other causes. Funded by the National Heart, Lung, and Blood Institute, the study included walking and riding a stationary bicycle for exercise. People with heart failure should talk with their doctors prior to sustained physical activity.
Obese children and teens are more likely than children of normal weight to suffer from allergies, particularly food allergies. Analyzing data on more than 4,000 children between the ages of 2 and 19, researchers found the obese to be about 26 percent more likely to have allergies. The results do not prove that obesity causes allergies — more investigation is needed. The study was funded by the National Institute of Environmental Health Sciences and the National Institute of Allergy and Infectious Diseases.

The first question in the Migraine 101 quiz in the Spring 2009 issue should have read: "A migraine headache usually begins with a visual disturbance called an aura (spots, dots, or even zigzag lines)." The answer should have been: "False. In most cases of migraine, there is no aura."
