Although large numbers of headache sufferers, particularly individuals who struggle with migraines, attribute their pain to the weather, there has been little scientific evidence to back up their assertions. Now, a study of more than 7,000 patients, led by researchers at Beth Israel Deaconess Medical Center (BIDMC), provides some of the first large-scale data on how environmental conditions -- weather, as well as air pollution -- influence headache pain. Reported in the March 10 issue of the journal Neurology, the findings demonstrate that higher temperatures, and to a lesser degree, lower barometric pressure, contribute to severe headaches. http://www.physorg.com/news155843261.html Medicine & Health Mon, 09 Mar 2009 18:48:23 EST news155843261 Men with a common genetic variant produce more than twice as much of a hormone known to increase blood pressure and blood sugar when they are angry, according to researchers from Duke University Medical Center. http://www.physorg.com/news155572711.html Medicine & Health Fri, 06 Mar 2009 14:39:18 EST news155572711 (PhysOrg.com) -- The combination of stress and obesity may significantly influence the development of type 2 diabetes among African-American women, with stress having a potentially greater role, according to researchers from Duke University Medical Center. http://www.physorg.com/news155493632.html Medicine & Health Thu, 05 Mar 2009 16:41:25 EST news155493632 The new medical subspecialty of Advanced Heart Failure and Transplant Cardiology will lead the way in providing technically advanced yet cost-effective care for patients with heart failure, says a perspective article in the March issue of the Journal of Cardiac Failure, official publication of the Heart Failure Society of America (HFSA) and the Japanese Heart Failure Society, published by Elsevier. http://www.physorg.com/news155473096.html Medicine & Health Thu, 05 Mar 2009 10:59:36 EST news155473096 A mutation of the influenza A(H1N1) virus that is resistant to the drug oseltamivir may pose a serious health threat to hospitalized patients who have a weakened immune system, according to a study to be published in the March 11 issue of JAMA, and being released early online because of its public health importance. http://www.physorg.com/news155223597.html Medicine & Health Mon, 02 Mar 2009 13:41:06 EST news155223597 An immune system response that is critical to the first stages of fighting off viruses and harmful bacteria comes from an entirely different direction than most scientists had thought, according to a finding by researchers at the Duke University Medical Center. http://www.physorg.com/news155137707.html Medicine & Health Sun, 01 Mar 2009 13:48:55 EST news155137707 UT Southwestern Medical Center's primary adult teaching hospital has cut its rate of preterm births by more than half in the past 15 years, even as national rates are rising, researchers have found. http://www.physorg.com/news154956040.html Medicine & Health Fri, 27 Feb 2009 11:22:16 EST news154956040 The experimental drug fampridine (4-aminopyridine) improves walking ability in some individuals with multiple sclerosis (MS).
