64th Annual Meeting Society of Thrombosis and Haemostasis Research Novel concepts for a lifetime challenge Bremen, Germany |18–21 February 2020 Book of Abstracts WELCOME ADDRESS Dear colleagues and friends, our congress motto “Novel concepts for a lifetime challenge” points out that many disorders in the field of thrombosis and haemostasis affect patients throughout their entire life. Thus, basic science and patient care should involve both, an interdisciplinary approach at a patient’s given age and a close collaboration of physicians and scientists specialised on different phases of the patient’s life, such as neonatologists, paediatricians, general practitioners and geriatricians. Understanding the natural history of bleeding and thrombotic disorders from a clinical and scientific perspective is key to providing our patients with the best possible treatment in a rapidly changing landscape of novel diagnostic tests and therapeutic agents. We feel that the Town Musicians of Bremen, as depicted in the annual meeting’s logo, nicely illustrate the urgent need for trustful teamwork in basic science and clinical practice. Only when we build on each other’s knowledge and experience, we can come up with “Novel concepts for a lifetime challenge”. We have received many outstanding contributions on a broad spectrum of basic and clinical research topics and hope that you enjoy reading the annual meeting's abstracts as much as we did!
