The time Anna stayed up all night

Almost precisely a decade ago, a young Atlanta lawyer named Anna was returning to work, after being treated for an extraordinary sleep disorder. Her story has been told here at Emory and by national media outlets. Fast forward a decade to Idiopathic Hypersomnia Awareness Week 2018 (September 3-9), organized by Hypersomnolence Australia. What this post deals with is essentially the correction of a date at the tail end of Anna’s story, but one with long-term implications Read more

Why is it so hard to do good science?

Last week, Lab Land put out a Twitter poll, touching on the cognitive distortions that make it difficult to do high-quality science. Lots of people (almost 50) responded! Thank you! We had to be vague about where all this came from, because it was before the publication of the underlying research paper. Ray Dingledine, in Emory’s Department of Pharmacology, asked us to do the Twitter poll first, to see what answers people would give. Dingledine’s Read more

Delivering nutrition to critical care patients

Emory clinical nutrition expert Thomas Ziegler, MD, has a case report article in the Sept. 10 issue of the New England Journal of Medicine.

The case report describes a woman with diabetes who needed surgery because of loss of blood flow to abdominal organs. While she is in intensive care after surgery, it becomes clear that a feeding tube leading from her nose to her stomach is not working. That makes her a good candidate for parenteral nutrition, or bypassing the digestive system and delivering nutrients directly into her blood.

Malnutrition is common in patients who are critically ill and often worsens with prolonged hospitalization. Some patients can’t eat normal food or benefit from a feeding tube into the stomach.

Yet few well-designed clinical trials studying parenteral nutrition have been conducted, Ziegler writes. He also notes that there is considerable debate over when parenteral nutrition is appropriate during critical care and how to administer it.

Ziegler’s own research has shown the beneficial effects of the amino acid glutamine, which must be added fresh to feeding formulas, for some critical care patients.

Several of the questions Ziegler outlines in his article will be issues investigators at Emory’s new Center for Critical Care will tackle. Recently, Timothy Buchman, MD, PhD, joined Emory to lead the critical care team.
