Extended cooling can prevent brain injuries, but this treatment is not always available in developing nations where advanced medical care is scarce. To address this need, Johns Hopkins undergraduates have devised a low-tech $40 unit to provide protective cooling in the absence of modern hospital equipment that can cost $12,000. http://medicalxpress.com/news/2013-03-low-cost-cooling-avert-brain-oxygen-starved.html Medical research Thu, 21 Mar 2013 16:02:21 EST news283100529 (Medical Xpress)—Concussions can occur in sports and in combat, but health experts do not know precisely which jolts, collisions and awkward head movements during these activities pose the greatest risks to the brain. To find out, Johns Hopkins engineers have developed a powerful new computer-based process that helps identify the dangerous conditions that lead to concussion-related brain injuries. This approach could lead to new medical treatment options and some sports rule changes to reduce brain trauma among players. http://medicalxpress.com/news/2013-03-athletes-soldiers-brain-concussions.html Neuroscience Tue, 05 Mar 2013 18:01:11 EST news281728854 (Medical Xpress)—With every sunrise and sunset, our eyes make note of the light as it waxes and wanes, a process that is critical to aligning our circadian rhythms to match the solar day so we are alert during the day and restful at night. Watching the sun come and go sounds like a peaceful process, but Johns Hopkins scientists have discovered that behind the scenes, millions of specialized cells in our eyes are fighting for their lives to help the retina set the stage to keep our internal clocks ticking. http://medicalxpress.com/news/2013-03-cell-death-retina-tune-internal.html Neuroscience Tue, 05 Mar 2013 17:56:25 EST news281728538 One in three diabetes patients at the Penal Health Center, located in the Penal region of Trinidad and Tobago, fail to take the medications their physicians prescribe for high blood sugar, blood pressure or cholesterol.

Some tweets are posted by people who have been sick with the virus, while others come from folks who are merely talking about the illness. If you are tracking actual flu cases, such conversations about the flu in general can skew the results. http://medicalxpress.com/news/2013-01-twitter-track-flu-screen-tweets.html Diseases, Conditions, Syndromes Fri, 25 Jan 2013 10:13:37 EST news278331210 Prostate cancer experts at Johns Hopkins have developed an updated version of the Partin Tables, a tool to help men diagnosed with prostate cancer and their doctors to better assess their chance of a surgical cure.
