PAD patients that use aspirin reduce risk of stroke, study finds

BY Michael Johnsen

CHICAGO In patients with peripheral artery disease, a blocked leg blood vessel, prophylactic use of aspirin either alone or in conjunction with dipyridamole did not reduce incidence of heart disease, but did reduce the risk of a nonfatal stroke, research published May 13 in the Journal of the American Medical Association has found.

The finding comes from a meta-analysis of studies around aspirin use with PAD.

Overall, studies found a 12% reduction in all cardiovascular events among patients receiving aspirin therapy, compared with those who were not. And while that reduction was considered statistically insignificant, the incidence of nonfatal stroke was 34% lower in the aspirin-taking group.

Antioxidants can help prevent heart attacks, study shows

BY Alaric DeArment

NEW YORK The bacteria-fighting enzyme that causes nasal mucus to turn green also causes damage during heart attacks, but scientists in Australia may have found a way to control it.

According to published reports, researchers at the University of Sydney’s Heart Research Institute and the Queensland University of Technology have found antioxidants that could control the enzyme myeloperoxidase and stop it from causing damage when white blood cells release it during heart attacks. Normally, the cells dump myeloperoxidase on bacteria to kill them.

The research will appear in Biochemical Journal.

NSF International develops online resource for supplements information

BY Michael Johnsen

ANN ARBOR, Mich. NSF International on Tuesday launched a new online resource, http://www.nsfsport.com, to provide information to help consumers, athletes and coaches choose safer, quality supplement products.

“We are pleased to see more user-friendly resources being placed in the hands of the public,” stated Liliana Begg, manager, Clean Sport Initiative. “The Clean Sport Initiative, which provides a forum for discussions on accidental doping will now have the support of value-added informational sites that provide consumers with the guidance they need when choosing nutritional supplements.”

NSF’s Athletic Banned Substances Certification Program certifies sports supplements that have met NSF’s certification guidelines and provides key preventive measures to protect against adulteration of products, verify label claims with product contents, as well as identify any banned substances in the finished product. The certification program has been recommended by key athletic organizations, including Major League Baseball, the Major League Baseball Players Association, the National Football League, the Professional Golf Association, the National Football League Players Association and the Canadian Centre for Ethics in Sports.

Additional information, such as recent news stories on doping in sports and educational resources, can also be found at http://www.nsfsport.com.
