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

Heart Month: Helping narrowed aortic valves

Celebrating February’s American Heart Month at Emory Heart & Vascular Center

Emory cardiologists are using a promising new non-surgical treatment option for patients with severe aortic stenosis.

Emory University Hospital is one of about 20 hospitals nationwide, and the only site in Georgia, to study this new technology – with 75 patients receiving new valves at Emory since the clinical trial started in October 2007. Researchers hope to receive U.S. Food and Drug Administration approval in late 2011.

The life threatening heart condition affects tens of thousands of Americans each year when the aortic valve tightens or narrows, preventing blood from flowing through normally.

Peter Block, MD

Peter Block, MD, professor of medicine, Emory School of Medicine, and colleagues are performing percutaneous aortic valve replacement as part of a Phase II clinical trial, comparing this procedure with traditional, open-heart surgery or medical therapy in high-risk patients with aortic stenosis.

The procedure provides a new way for doctors to treat patients who are too ill or frail to endure the traditional surgical approach.

During the procedure, doctors create a small incision in the groin or chest wall and then feed the new valve, mounted on a wire mesh on a catheter, and place it where the new valve is needed.
