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

Radiologists wrestle with robots – ethically

Radiologists look at and analyze images, tasks computer algorithms can do. This is fertile soil for artificial intelligence (AI) — enough so that some predict that AI will replace radiologists.

John Banja, PhD

Emory bioethicist John Banja says: don’t believe the hype. AI will generate tools radiologists will want to use, he says. But human experts will have plenty to do, including making sure that the algorithms are properly vetted and trained on appropriate data.

“We already know what a lot of the ethical issues are going to be…informed consent, privacy, data protection, ownership, all that kind of stuff,” Banja recently told Health Imaging. “What we need to do is drill down to the next level, especially the practice level.”

Banja has received a grant from the Advanced Radiology Services Foundation to support a series of podcasts with radiologists over the next two years. He will be teaming up with Emory radiologist Rich Duszak, a specialist in health policy, and Norm Beauchamp, medical dean at Michigan State.

Banja and Duszak are still planning podcast sessions and lining up interviews, but they said the first episode will be on “AI hype”, and the second will cover standard of care/medical malpractice, with future issues on FDA standards.

Duszak comments on how radiologists need to take control of the algorithms in this video.

Also, with radiology chair Carolyn Meltzer, Banja recently published a review on ethics related to radiology and AI, exploring issues such as selection bias and stretching algorithms too far. Read more
