Clot-busting drugs may be safe for patients who wake up experiencing stroke symptoms, according to preliminary research presented at the American Stroke Association's International Stroke Conference 2012. In "wake-up" stroke, the person wakes up with symptoms after going to sleep with none. Not knowing when the stroke began excludes these patients from anti-clotting drugs that must be given within 4.5 hours of the beginning of the stroke. "Because wake-up strokes are common, occurring...

Substance In Cancer Medicine May Help Prevent Heart Attacks

Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden have been using a substance found in cancer and epilepsy drugs to help stimulate the body´s natural defense mechanism against blood clots. The body contains a system that helps break down blood clots before they can damage the heart, called the fibrinolytic system. This system “sprays” an enzyme on the clot before it can stop blood flow to the heart, causing a heart attack. This system can be...

A targeted, nanoparticle gelatin-based clot-busting treatment dissolved significantly more blood clots than a currently used drug in an animal study of acute coronary syndrome presented at the American Heart Association's Scientific Sessions 2011. The new drug-delivery system used gelatin to deactivate the clot-busting drug tissue plasminogen activator, or tPA, to treat acute coronary syndrome. Soundwaves were then used to reactivate tPA once it reached the blood clot. It is considered a...

Innovative technology improves care and reduces costs The use of long-distance video and data hookups to link remote community hospitals with stroke neurologists in large centres provides the same level of care as having everyone in the same room, according to a new study presented today at the Canadian Stroke Congress. The study found that rural patients examined with the aid of a technology called Telestroke received an important stroke drug, tPA, at the same rate as patients treated...

(Ivanhoe Newswire) — Using long-distance video and data hookups in remote community hospitals to treat stroke, provides the same level of care as having everyone in the same room, according to a new study. The study found that rural patients examined with the aid of a technology called Telestroke received an important stroke drug, tPA, at the same rate as patients treated in specialized urban centers, explained Dr. Thomas Jeerakathil, a neurologist at the University of Alberta...

The percentage of graduating neurology residents comfortable treating stroke with a clot-busting drug has increased dramatically over the past 10 years, according to research published in Stroke: Journal of the American Heart Association. In a survey, the number of residents reporting feeling comfortable using tissue plasminogen activator (tPA) increased from 73 percent in 2000 to 94 percent in 2010. Furthermore, 95 percent in 2010 had used tPA compared to 80 percent in the earlier survey. Of...

A naturally occurring substance shrank the size of stroke-induced lesions in the brains of experimental mice "” even when administered as much as 12 hours after the event, Stanford University School of Medicine researchers have shown. The substance, alpha-B-crystallin, acts as a brake on the immune system, lowering levels of inflammatory molecules whose actions are responsible for substantial brain damage above and beyond that caused by the initial oxygen deprivation of a stroke. The...

Education needed to close the gap, improve outcomes A citywide study published online in today's issue of Stroke: Journal of the American Heart Association demonstrates racial disparities in the use of clot-busting drugs to treat acute ischemic stroke, the most common type of stroke. According to the study's results, significantly fewer black patients receive the drug tPA than whites because of delays in seeking emergency care and the presence of medical conditions that exclude them from...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
