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

Brain surgery with a light touch

As part of reporting on neurosurgeon Robert Gross’s work with patients who have drug-resistant epilepsy, I interviewed a remarkable woman, Barbara Olds. She had laser ablation surgery for temporal lobe epilepsy in 2012, which drastically reduced her seizures and relieved her epilepsy-associated depression.

Emory Medicine’s editor decided to focus on deep brain stimulation, rather than ablative surgery, so Ms. Olds’ experiences were not part of the magazine feature. Still, talking with her highlighted some interesting questions for me.

Emory neuropsychologist Dan Drane, who probes the effects of epilepsy surgery on memory and language abilities, had identified Olds as a good example of how the more precise stereotactic laser ablation procedure pioneered by Gross can preserve those cognitive functions, in contrast to an open resection.
