Can blood from coronavirus survivors save the lives of others?

Donated blood from COVID-19 survivors could be an effective treatment in helping others fight the illness – and should be tested more broadly to see if it can “change the course of this pandemic,” two Emory pathologists say. The idea of using a component of survivors’ donated blood, or “convalescent plasma,” is that antibodies from patients who have recovered can be used in other people to help them defend against coronavirus.

Targeting metastasis through metabolism

Research from Adam Marcus’ and Mala Shanmugam’s labs was published Tuesday in Nature Communications – months after we wrote an article for Winship Cancer Institute’s magazine about it. So here it is again! At your last visit to the dentist, you may have been given a mouth rinse with the antiseptic chlorhexidine. Available over the counter, chlorhexidine is also washed over the skin to prepare someone for surgery. Winship researchers are now looking at chlorhexidine 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
