A new generation of scientists and physicians born in the 1980s and 1990s is rising, more than 60 years after establishing the Deutsche Arbeitsgemeinschaft für Blutgerinnungsforschung (DAB), today the Gesellschaft für Thrombose- und Hämostaseforschung (GTH), and 40 years after the first issue of Hämostaseologie—Progress in Haemostasis.[1]
[2] Their careers unfold at a time when structured learning programs are being created, the interest in thrombosis and hemostasis expands, and networking opportunities reach their highest potential. This period also coincides with the achievement, at least to a large part, of previously unreachable goals, such as a decrease in mortality related to severe disorders of coagulation, notably pulmonary embolism[3] and hemophilia.[4] In the years to come, the millennial generation of thrombosis and hemostasis experts will shape scientific societies, improve evidence for clinical care, and increase public awareness with the commitment of representing a positive clustering force.
This special issue of Hämostaseologie—Progress in Haemostasis hosts 10 narrative reviews authored by 29 young experts — in a well-balanced sex ratio — of the upcoming generation of leaders in the field. Although as many as 13 countries and 23 institutions are represented, this issue by no means presumes to (and cannot) be exhaustive. Instead, its objective is to give a snapshot of global positions and interests, ranging across several clinical conditions and research targets.
As a highly interdisciplinary field in medicine, thrombosis and hemostasis necessarily demands the active interaction of a broad spectrum of clinicians and scientists. Thus, it is not really unexpected that the authors identified themselves as internists, hematologists, intensive care physicians, cardiologists, pulmonologists, hemostasis experts, angiologists, biochemists, biologists, and biostatisticians.
The structure of these articles aims to provide the readers with a comprehensive overview of specific topics, to discuss unmet needs, and to present novel research activities that may dramatically change or even revolutionize the field in future years. The final paragraph of each review contains a section denominated time capsule.[5] In this capsule, the authors had been asked to transmit messages, outline expectations, or make predictions regarding the reviewed topic. The receivers are the authors themselves in the year 2050 and the next generation of physicians and scientists in thrombosis and hemostasis.
In their article, Drs. van Es, Ay, and Jara-Palomares discuss different screening strategies and risk assessment models for occult cancer after (unprovoked) venous thromboembolism (VTE).[6] Elegant solutions to solve this arcana may be around the corner.
Drs. Gautam, Sebastian, and Klok dissect the partially overlapping entities of chronic thrombosis, recurrent thrombosis, and postthrombotic syndrome, and elucidate clinical implications. The readers are virtually accompanied from the radiology department to patient bedside.[7]
Old age has taken on a new meaning in our societies and this has a major impact on the delivery of patient care and medical therapies. Drs. Giustozzi, Castellucci, and Barnes review available data on the efficacy and safety of anticoagulant treatment for atrial fibrillation and VTE in nonagenarians.[8]
The idea that some venous thromboses have an infectious origin is consistent with the observation that a thrombus may co-occur with local infection and inflammation. Drs. Valerio and Riva process and develop this key concept in their summa, and provide the readers with a detailed update of the available knowledge.[9]
In their review, Drs. Trinchero, Sholzberg, and Matino give an overview of the medical treatment of hemophilia A and B. A revolution in hemophilia treatment has occurred over the past 5 years and the authors discuss novel opportunities and challenges.[10]
Thrombotic thrombocytopenic purpura is a rare, potentially life-threatening disorder: Drs. Roose and Joly comprehensively summarize its pathophysiology and management, and identify a few solid pillars to sustain the development of curative treatments.[11]
Drs. Zaninetti, Sachs, and Palankar address the current available methods for biophysical investigations of platelets and the possible translation into the field of inherited platelet disorders, going into depth on biological and technical details.[12]
The pathophysiology of several forms of pulmonary hypertension remains to be fully clarified. The rationale of anticoagulant use in these patients and the available data are discussed by Drs. Bertoletti, Mismetti, and Giannakoulas. The authors did not forget to emphasize the potential risks related to the use of direct oral anticoagulants in this patient population.[13]
Drs. Skeith, Blondon, and Ní Áinle present the most recent evidence to better understand hemostatic mechanisms of preeclampsia, placenta-mediated pregnancy complications, and in women with thrombophilia. The review is conducted with the aid of a few illustrative clinical cases.[14]
Can we measure the individual prothrombotic or prohemorrhagic tendency by global coagulation assays? This question is answered by Drs. Reda, Morimont, Douxfils, and Rühl, who foresee that these tests will play an important role in the future of laboratory diagnostics of hemostasis and thrombosis.[15]
During the preparation of this special issue, we witnessed the coronavirus disease 2019 (COVID-19) outbreak. Most of us are being actively involved in patient care in parallel with research activities. Today, we know that COVID-19 is characterized by a substantial infectious rate and fatality, but it is still too early to speculate how the pandemic will evolve on a global scale.[16] Apart from the predilection of the virus for epithelial cells, bilateral pneumonia causing an exaggerated inflammatory response, pulmonary-induced coagulopathy and thromboembolic complications are integral features of the disease, at least in its most severe forms.[17]

[20] Facing with such a global challenge, we, as young thrombosis and hemostasis experts, are called on duty to find innovative solutions.
