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

EHR data superior for studying sepsis

Are there more cases of a given disease because something is causing more, or because doctors have become more aware of that disease? A recent paper in JAMA tackles this question for sepsis, the often deadly response to infection that is the most expensive condition treated in US hospitals.

Researchers from several academic medical centers, including Emory, teamed up to analyze sepsis cases using two methods. The first is based on the ICD (International Classification of Diseases) codes recorded for the patient’s stay in the hospital, which the authors refer to as “claims-based.” The second mines electronic medical record (EHR) data, monitoring the procedures and tests physicians used when treating a patient. The first approach is easier, but might be affected by changing diagnosis and coding practices, while the second is not possible at every hospital.

“This project was undertaken by several large, high quality institutions that have the ability to well characterize their sepsis patients and connect their EHR data,” says Greg Martin, MD, who is a co-author of the JAMA paper along with David Murphy, MD, PhD. The lead author, Chanu Rhee, MD, MPH, is from Brigham and Women’s Hospital, and the entire project was part of a Prevention Epicenter program sponsored by the Centers for Disease Control and Prevention.  Read more

Test of megadose vitamin D in intubated critical care patients

Whether dietary supplementation with vitamin D is beneficial, in terms of preventing disease, has been controversial. However, vitamin D has been reported to increase immune cells’ production of microbe-fighting proteins. That’s why Emory doctors have been testing whether high doses of vitamin D could be helpful for critical care patients, who need to ward off infections.

The results of a small-scale clinical trial, presented in Denver this week at the American Thoracic Society meeting, suggest that high doses of vitamin D could decrease the length of hospital stays in critically ill patients with respiratory failure. Read more
