“Wow! I never even heard about that article!” All too often, new discoveries in the field of Transfusion Medicine can escape our notice. Two authors of a great synopsis of 2016-17 critical developments are here to help get you caught up!
Every year, the AABB Clinical Transfusion Medicine Committee develops a detailed synopsis of recent developments in Transfusion Medicine to present to the AABB Governing Board. This year, for the first time, that summary is available to the rest of us! Drs Claudia Cohn and Melissa Cushing (along with Ellen Klapper and James Kelley) edited a condensed version published in Transfusion in April 2018, and they are here to guide you through what you might have missed!
Critical developments of 2016-17
Claudia and Melissa will give you the highlights in seven key areas of Transfusion Medicine:
- Reversal of bleeding in hemophilia and for patients on direct oral anticoagulants (begins at 9:25)
- Duration of RBC storage (16:15)
- Pathogen inactivation/reduction (25:45)
- Blood donor characteristics and patient outcomes (33:25)
- Pediatric transfusion medicine (39:00)
- Transfusion approach to hemorrhagic shock (43:50)
- Therapeutic apheresis and extracorporeal photopheresis (50:25)

Claudia Cohn, MD PhD earned her PhD in Immunology and Infectious Diseases from the Johns Hopkins University, and subsequently earned her MD at Louisiana State University. After finishing her Transfusion Medicine fellowship at University of California, San Francisco, Dr. Cohn joined the faculty at the University of Minnesota, in Minneapolis, where she is Medical Director of the Blood Bank, Associate Medical Director of the HLA lab and Associate Head of Labs. Dr. Cohn’s research interests include clinical platelet transfusions; patient blood management and applying technology to enhance laboratory utilization efforts.
Melissa Cushing, MD attended Duke University, Georgetown University School of Medicine, Emory University School of Medicine for Clinical Pathology Residency Training, and John Hopkins School of Medicine for her Transfusion Medicine Fellowship. She is an Associate Professor of Clinical Pathology and Laboratory Medicine at Weill Cornell Medical College in New York City, and Associate Director of the Clinical Laboratories and the Director of Transfusion Medicine and Cellular Therapy at New York-Presbyterian Hospital, Weill Cornell Campus. Dr. Cushing’s areas of expertise include the treatment of perioperative bleeding, patient blood management, and innovation in transfusion medicine.
