ASPirin in Reducing Events in the Elderly

Topic:  A National Institute on Aging clinical trial to test whether taking aspirin contributes to good health in seniors.  

Purpose:  To determine whether low dose aspirin will extend the duration of disability-free life in an aging population. The study will examine whether the potential benefits of this drug (particularly the prevention of heart disease, stroke, and vascular dementia) outweigh the risks of severe bleeding in seniors ages 65 and older.

Addressing Childhood Obesity in Primary Care

Background: Although childhood obesity is a major health problem in the United States, many physicians are not aware of all the elements in the American Academy of Pediatrics (AAP) Expert Committee recommendations on Assessment of Child and Adolescent Overweight and Obesity (Barlow 2007). AT the same time, some parents can misclassify their children, thining they appear healthy even when they are overweight or obese (Contento 2003).

Purpose: The purpose of this survey study is to, 1)  assess physicians' knowledge, attitudes, and behaviors regarding the management of childhood obesity in their practices; and, 2)  assess parents' perceptions of their child's weight and body size, as well as usual diet, physical activity, and screen time (TV, computer, video games) behaviors in the household. If you are interested in participating in this survey study, please contact Walter Calmbach, MD at or at (210) 358-3200.
