AHA to Fund Research Network for the Prevention of Heart Disease, Stroke
With a $15 million grant from the American Heart Association (AHA), four major medical institutions are coming together to form a research network with the goal of preventing heart disease and stroke. The Strategically Focused Prevention Research Network Centers will include investigators at Northwestern University in Chicago, Vanderbilt University in Nashville, the Icahn School of Medicine at Mount Sinai in New York City and the University of Texas-Southwestern Medical Center in Dallas. “Heart attack and stroke can strike suddenly, and frequently without warning. The best way to reduce premature mortality from cardiovascular diseases and stroke is to prevent the development of the risk factors that lead to these conditions,” said AHA President Elliott Antman, MD, professor of medicine at Harvard Medical School and a senior physician in the cardiovascular division of the Brigham and Women’s Hospital in Boston, in a release. “Scientists working in these research centers are helping to discover the mechanisms that will allow all Americans to live healthier lives, helping lead us to a culture of health.” Read more on heart health.
Study: One-Third of U.S. Total Knee Replacements ‘Inappropriate’
Approximately one-third of all total knee replacements in the United States are unnecessary and “inappropriate” under a patient classification system used in Spain, according to a new study in the journal Arthritis & Rheumatology. Researchers said the findings demonstrate a need for the United States to develop similar patient selection criteria so as to limit the unneeded surgeries. There are more than 600,000 total U.S. knee replacements annually—meaning that approximately 200,000 are unnecessary, according to the study—and from 1991 to 2010 the number of Medicare-covered replacements climbed by approximately 162 percent annually.

Kids’ ADHD Medications Not Linked to Increase Risk of Substance Abuse
While children with attention-deficit/hyperactivity disorder (ADHD) are twice as likely to abuse drugs, the medications prescribed to treat ADHD do not play a role in the increased risk, according to a new study in the journal Pediatrics. In fact, researchers determined that the combination of behavioral techniques and ADHD medications actually lowers the risk of substance abuse. "Obviously, the medications that are used to treat ADHD have the potential for abuse, but the vast majority of children with ADHD do not develop a substance abuse problem," said Michael Duchowny, MD, a pediatric neurologist at Miami Children's Hospital. "More research has to be done to find out why some children are more susceptible than others." Common ADHD medications include amphetamines such as Adderall or Dexedrine, and methylphenidates such as Concerta, Metadate CD or Ritalin. Read more on substance abuse.
