Fermentation byproduct suppresses seizures in nerve agent poisoning

A compound found in trace amounts in alcoholic beverages is more effective at combating seizures in rats exposed to an organophosphate nerve agent than the current recommended treatment, according to new research published Read more

Post-anesthetic inertia in IH

A recent paper from neurologists Lynn Marie Trotti and Donald Bliwise, with anesthesiologist Paul Garcia, substantiates a phenomenon discussed anecdotally in the idiopathic hypersomnia (IH) community. Let’s call it “post-anesthetic inertia.” People with IH say that undergoing general anesthesia made their sleepiness or disrupted sleep-wake cycles worse, sometimes for days or weeks. This finding is intriguing because it points toward a trigger mechanism for IH. And it pushes anesthesiologists to take IH diagnoses into Read more

Telomere Shortening, Regenerative Capacity, and Cardiovascular Outcomes Nov. 13, 4:45 pm, Room 346-347

Aging, in general, depletes our bodies’ regenerative capacities. Arshed Quyyumi, MD and colleagues at Emory Clinical Cardiovascular Research Institute have shown how circulating progenitor cells or CPCs, which regenerate blood vessels and correlate with outcomes in cardiovascular disease, are a finite resource.

Working with Quyyumi, research fellow Muhammad Hammadah, MD is presenting data on how telomere length interacts with the levels of CPCs, in a study of mental stress ischemia in 566 patients with stable coronary artery disease. Telomeres tend to shorten with ageing and cellular stress, and their length has been a widely studied biomarker.

Hammadah concludes that low leukocyte telomere length is associated with decreased regenerative capacity, independently of age and cardiovascular risk factors. However, telomere length and CPC levels are independent and additive predictors of adverse cardiovascular outcomes (such as death, heart attack, stroke, or hospitalization for heart failure), he finds. Hammadah is a finalist for the Elizabeth Barrett-Connor Research Award for Young Investigators in Training.
