Biomarker Predicts Osteoarthritis

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

Biomarkers are an important part of the medical diagnostic toolkit. Diagnostics isn't as flashy as the search for a cure, but bear in mind that many age-related conditions could be ameliorated or avoided entirely if predicted or otherwise caught in very early stages. EurekAlert reports on the identification of a biomarker for osteoarthritis: "a chronic degenerative joint disease, osteoarthritis (OA) is a common cause of pain and disability among older Americans. OA of the knee affects up to 6 percent of the older population, while OA of the hip affects about another 3 percent. While treatments vary, there is hope that early intervention - before joint destruction can be clearly seen and measured on an X-ray image - will improve outcomes."
