New research presented at the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), shows that patients with atherosclerosis receiving statin therapy had a significantly reduced risk of developing venous thromboembolism (VTE) -a collective term for DVT (blood clot) and pulmonary embolism (PE) -than patients not on statin therapy. Furthermore, patients on a higher dose of statins had the least likelihood of developing VTE. http://www.physorg.com/news176478450.html Medicine & Health Tue, 03 Nov 2009 14:20:02 EST news176478450 William Kuo, MD, was the on-call interventional radiologist one Friday night three years ago when he received a call from the intensive care unit at Stanford Hospital & Clinics.

Adhering to the undersides of vessels, carpets of the crustaceans can increase fuel consumption by as much as 25%. Ship owners would love to know how to stop these hitchhikers gluing on, but before you can learn how to disrupt an adhesive, you have to understand the curing process. Curious about many aspects of the crustacean's lifestyle, Dan Rittschof from Duke University decided to find out how barnacle adhesive polymerizes. http://www.physorg.com/news174891043.html Chemistry Fri, 16 Oct 2009 06:20:02 EST news174891043 Futuristic plans to grow replacement organs, bones or muscles for soldiers maimed on the battlefield or patients suffering from debilitating disease or injury won't be anything but science fiction unless new blood vessels can grow into that tissue. http://www.physorg.com/news174652957.html Medicine & Health Tue, 13 Oct 2009 11:44:43 EST news174652957 Many patients urgently admitted to hospital with cerebral infarction state that they were under great stress over a prolonged period prior to suffering their stroke, is shown in a unique patient study conducted in cooperation between the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital, Sweden. http://www.physorg.com/news173624872.html Medicine & Health Thu, 01 Oct 2009 14:08:18 EST news173624872 Even though the incidence of atrial fibrillation is higher in men than women, a review of past studies and medical literature completed by cardiac experts at Rush University Medical Center shows that women are more likely than men to experience symptomatic attacks, a higher frequency of recurrences, and significantly higher heart rates during atrial fibrillation, which increases the risk of stroke. http://www.physorg.com/news172842438.html Medicine & Health Tue, 22 Sep 2009 13:10:11 EST news172842438 Deep Venous Thrombosis (DVT) is a serious condition that involves the formation of a blood clot inside of a deep vein usually in the legs.

Scientists at Heidelberg University Hospital have explained the mechanism of this clinical paradox for the first time on an animal model. Mice with a greater tendency to form blood clots have larger plaques in their vessels, but they are more stable. Thus, there is less risk that these plaques will rupture and obstruct circulation. The results of the study have been published in the prestigious journal Circulation. http://www.physorg.com/news170328047.html Medicine & Health Mon, 24 Aug 2009 10:21:46 EST news170328047 (AP) -- Abbott Laboratories Inc. is expanding a study of its top-selling heart stent by more than 2,000 patients, who may also be put in a second, landmark stent study meant to find the best way to prevent potentially fatal blood clots. http://www.physorg.com/news169384157.html Medicine & Health Thu, 13 Aug 2009 12:09:44 EST news169384157 The dean of the University of Oklahoma College of Public Health and a team of scientists worldwide have found a better way to prevent deadly blood clots after joint replacement surgery - a major problem that results in thousands of unnecessary deaths each year.

The discovery might offer a new way to fight clot formation before it can even begin, according to the researchers. http://www.physorg.com/news159105219.html Medicine & Health Thu, 16 Apr 2009 12:54:10 EST news159105219
