World Thrombosis Day: Sunday, October 13

About 900,000 people in the U.S. alone are affected by blood clots each year, and about 100,000 of those will die -- greater than the total number of people who lose their lives each year to AIDS, breast cancer, and motor vehicle crashes combined.  Even more startling: around the world, one in four people worldwide are suffering and dying from conditions caused by thrombosis, according to the WTD website.

We would like to thank our HTRS member physician scientists, PhD investigators, thrombosis nurses, and all allied health professionals whose career passions revolve around advancing research and clinical treatment for patients with thrombosis.  Specially, we acknowledge HTRS Director Mary Cushman, MD, MSc, who recently helped moderate the World Thrombosis Day 2019 Webinar co-hosted by International Society on Thrombosis and Haemostasis (ISTH) and the Centers for Disease Control and Prevention (CDC).  The topic was "Top 3 Considerations for the Prevention of Hospital-Associated VTE."

If you'd like to join the WTD movement and/or find a local event taking place this Sunday, 10/13, visit www.worldthrombosisday.org/action/partners.
