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

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

Emory, Georgia Tech tackle abdominal aortic aneurysms

Abdominal aortic aneurysms (AAA) are a major cause of illness and death in the U.S., with the incidence increasing dramatically over the age of 55. These aneurysms are a widening and bulging of the large artery that runs through the body from the heart into the abdomen. They often go undetected until they suddenly rupture, often resulting in death within minutes.

A team of physicians and engineers from Emory and Georgia Tech is studying the biology and biomechanics of vascular inflammation and disturbed blood flow in AAAs to understand how they develop and could be prevented or detected earlier.

Cardiologist and biomedical engineer Robert Taylor is leading the Biomedical Engineering Partnership, funded by $6 million from the NIH.

Taylor points out that predicting the likelihood of aneurysm rupture is extremely difficult and patients often don’t notice them until they already are leaking or ruptured. Even small aneurysms often expand rapidly and rupture. He and his team will try to pin down specific risk factors for AAAs, which they think differ from traditional cardiovascular risk factors.
