In this episode we interview two of the authors of a recent paper, Diagnosis and management of severe congenital protein C deficiency (SCPCD): Communication from the SSC of the ISTH, Dr Maha Othman and Dr Leonardo Brandao on this paper from the Journal of Thrombosis and Haemostasis. 2022;20:1735–1743. Severe congenital protein C deficiency (SCPCD) is rare and there is currently substantial variation in the management of this condition. A joint project by three Scientific and Standardization Committees of the ISTH was developed to review the current evidence and help guide on diagnosis and management of SCPCD.About our guests:Dr. Maha Othman is a clinical pathologist/hematologist with specialized training in haemostasis laboratory testing and molecular genetics of bleeding disorders. She obtained her medical degree and MSc in Clinical Pathology in Mansoura University in Egypt. She then completed her PhD in Pathology from Southampton University, UK. After this, she pursued post-doctoral research training in molecular genetics of hemophilia and von Willebrand disease with Dr. David Lillicrap, at Queen’s University, Canada. Dr. Othman is currently a full Professor at the School of Medicine, Queen’s University and at St Lawrence College, Kingston, Ontario. Her research interests include the clinical and molecular aspects of von Willebrand disease and platelet disorders particularly PT-VWD, and thromboelastography assessment of coagulopathies in women, pregnancy and cancer. She has more than 100 research papers and her research is recognized internationally. She is an editor for Seminars in Thrombosis and Haemostasis and Research and Practice in Thrombosis and Haemostasis Journals. She is a reviewer for a number of Haemostasis journals and a member of several scientific organizing committees on women’s health, and advisory boards for international haemostasis conferences. She is the previous Chairman of the Scientific and Standardization Committee (SSC) on Women’s Health Issues in Thrombosis and Haemostasis of the ISTH and currently CO-Chair on the SSC for DIC. She is a passionate educator and mentor and an advocate for rare bleeding disorders and bleeding and clotting disorders in women.Dr. Leonardo Brandão  is a native Brazilian who joined the staff at The Hospital for Sick Children in 2004. Since 2019, he has been the Thrombosis Program director. He obtained his medical degree at the University of São Paulo (USP) School of Medicine (FMUSP) before moving to North America, where he completed his post-graduate training (Paediatrics Residency at Emory University, Atlanta/GA, Paediatric Haematology/Oncology fellowship at St. Jude Children's Research Hospital, Memphis/TN, and a second fellowship in Paediatric Coagulation at Weill Cornell University, New York/NY). After finishing his training, he moved to Canada to focus on the field of paediatric thrombosis at SickKids. He is the past-chair of the thrombosis committee for the Canadian Pediatric Thrombosis Hemostasis Network (CPTHN), past-Canadian representative-elect for the Hemostasis and Thrombosis Research Society (HTRS), past-member of the first paediatric venous thromboembolism panel for the American Society of Hematology (ASH), past-co-chair of the paediatric thrombosis subcommittee for the International Society on Thrombosis and Hemostasis (ISTH), and a member of Thrombosis Canada.
