Myeloproliferative neoplasms are acquired hematological malignancies, mainly affecting the adult and whose morbidity and mortality stems from haemostasis disorders. The most frequently encountered complications include thrombosis, affecting preferentially the arterial territory, but also atypical locations such as splanchnic vein thrombosis. The pathophysiology of these thromboses is complex and involves different actors: blood cells, endothelium and flow conditions. ⋯ In these patients, platelet dysfunctions and/or acquired Willebrand syndromes can be found. The pathophysiology of thrombosis and platelet dysfunction during myeloproliferative neoplasms remains to date partially unknown. In this review, we offer to focus on physiopathological mechanisms as well as the latest advances in their understanding.

Historical Article
[Scientific misconduct: A major threat for medical research].
Scientific misconduct (fabrication, falsification, and plagiarism) and detrimental research practices (selective reporting of data, inappropriate citation practice, ghostwriting) are admitted respectively by 2 % and 33 % of researchers. The consequences of scientific misconduct and detrimental research practices are disastrous, both for the doctors, who are the most affected researchers in view of the number of retracted articles, and for the patients, victims of false information that may have health consequences. In order to fight against the causes (promotion of doctors and allocation of resources to clinical wards and laboratories on purely quantitative research criteria, lack of training in scientific integrity in medical studies, heterogenous quality of reviewing, legal impunity), there are legislative, academic, technological and editorial solutions, but radical and urgent cultural change is needed first.
