Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw 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.
