An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association’s 2012 international conference in New Orleans on Feb. 3.

The SOLITAIRE Flow Restoration Device is among an entirely new generation of devices designed to remove blood clots from blocked brain arteries in patients experiencing stroke. It has a self-expanding, stent-like design and, once inserted into a clot using a thin catheter tube, it compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel. (more…)

*Study implicates “arms race” between genes and germs*

Biologists have found new evidence of why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs–even though some of those genes make vertebrate animals susceptible to infections and to autoimmune diseases.

“Major histocompatibility complex” (MHC) proteins are found on the surfaces of most cells in vertebrate animals. They distinguish proteins like themselves from foreign proteins, and trigger an immune response against these foreign invaders. (more…)

Researchers at Yale School of Medicine have, for the first time, described the genetic basis of endometriosis, a condition affecting millions of women that is marked by chronic pelvic pain and infertility. The researchers’ discovery of a new gene mutation provides hope for new screening methods. (more…)

Lecture or Listen: When Patients Waver on Meds

*According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits.*

PROVIDENCE, R.I. [Brown University] — Take your medicine, Doctor’s orders. It’s a simple idea that may seem especially obvious when the pills are the antiretroviral (ARV) drugs that add decades to the lives of HIV-positive patients. But despite the reality that keeping up with drug regimens is not easy for many patients, a new analysis of hundreds of recorded doctor’s office visits finds that physicians and nurse practitioners often still rely on lecturing, ordering, and scolding rather than listening and problem solving with their patients.

GAINESVILLE, Fla. — Blueberry wine can provide more potentially healthy compounds than white wines and many red wines, according to a new University of Florida study.

Researchers with UF’s Institute of Food and Agricultural Sciences measured antioxidant content in a Florida-produced blueberry wine and compared it to published reports of antioxidant content in white and red wines made from grapes. Antioxidants are compounds that may offer cells protection from damaging molecules called free radicals. (more…)
