CWRUmedicine Annual Research Day

April 13, 2010

CWRUmedicine Annual Research DayResearch Day provides an opportunity for researchers in training at the Case Western Reserve University Department of Medicine to present their biomedical research in a public forum.

This group includes trainees at all levels of programming, including graduate, undergraduate, medical and MD/PhD students, as well as postdoctoral fellows and researchers and clinical residents and fellows.

Research Day also presents an opportunity for colleagues and visitors to learn about the cutting edge research occuring at Case Medical Center.

With multiple posters representing a wide array of research topics are displayed throughout the day, with presenters on hand to discuss their projects and research findings with visitors and guests.

Susan Redline discusses Sleep Apnea Increases Stroke Risk with WebMD

Moderate to Severe Sleep Apnea Triples Stroke Risk in Men, Study Finds

WebMD | April 8, 2010

Obstructive sleep apnea more than doubles the risk of stroke in men and also increases the danger in women, new research indicates.

The finding comes from a major study of 5,422 people aged 40 and older who had no history of stroke. Researchers say increased risk of stroke appeared in men with mild sleep apnea and rose with severity.

Men with moderate to severe sleep apnea were about three times more likely to have a stroke than men with mild or no sleep apnea, researchers say.

The increased risk of stroke in women with obstructive sleep apnea was significant only in cases of severe apnea, according to the study, published in the American Journal of Respiratory and Critical Care Medicine.

Obstructive Sleep Apnea and Stroke

Data were taken from the Sleep Heart Health Study, which is ongoing at a number of locations. The participants in the beginning performed a standard at-home sleep test to determine whether they had sleep apnea, and if so, its severity.

They were followed for about nine years, and during that time, 193 suffered strokes — 85 men out of 2,462 enrolled and 108 women out of 2,960.

“Although more women had strokes, relatively more men with sleep apnea than without sleep apnea had strokes, and less so in women,” study author Susan Redline, MD, MPH, of Case Western Reserve University in Cleveland, tells WebMD in an email. “I think that the relatively greater impact of sleep apnea on risk of stroke in men relates to the likely longer duration of sleep apnea in men than women.”

Researchers say more than 15 million strokes occur worldwide every year, and that about a third are fatal. Increased risk of stroke in people with sleep apnea exists even without other risk factors, such as weight, high blood pressure, race, diabetes, and smoking.

Men may be more at risk because they develop sleep apnea at younger ages, the researchers say, and thus go untreated for longer periods.

CWRUmedicine and UH develops New Drugs to improve oxygen delivery to tissues

April 8, 2010

Case Western Reserve University and University Hospitals are pleased to announce the awarding of a $4.7 million contract from the Defense Advanced Research Projects Agency (DARPA) to Dr. Jonathan Stamler, Director of the Institute for Transformative Molecular Medicine (ITMM).

The grant will fund development of a new class of drugs that selectively vasodilate under hypoxia and thereby enhance performance at high altitude (e.g. soldiers on mountains in Afganistan).

It is also anticipated that the grant will generate new physiologic information on high-altitude adaptation and new therapeutic interventions to treat patients suffering from conditions where oxygen delivery is impaired, including heart failure, ischemic heart disease, stroke, sickle cell disease and diabetes.

Studies will involve a transdisciplinary approach, including the Department of Anesthesia (James Reynolds) the division of Pulmonary Medicine (Kingman Stroh), and the Harrington-McLaughlin Cardiovascular Institute (Sahil Parikh).

New Research Published on Antibiotic resistance determinants in Acinetobacter spp

March 31, 2010

We explored the association of antibiotic-resistant phenotypes and genotypes in Acinetobacter spp with clinical outcomes and characteristics in 75 patients from a major military treatment facility. Amikacin resistance was associated with nosocomial acquisition of A baumannii, and carbapenem resistance and bla(OXA-23) were associated with the need for mechanical ventilation. The presence of bla(OXA-23) also correlated with longer hospital and ICU stay. Associations between bla(OXA-23) and complexity, duration, and changes made to antibiotic regimens also existed.
