The objective of this work is to generate recommendations on the management of allogeneic stem cell transplantation (allo-SCT) in primary myelofibrosis (PMF). A comprehensive systematic review of articles published between 1999 and 2015 (January) was used as a source of scientific evidence. The recommendations were produced through a Delphi process involving a panel of 23 experts appointed by the European LeukemiaNet and the European Blood and Marrow Transplantation Group. ⋯ Strategies such as discontinuation of immunosuppressive drugs, infusion of donor lymphocytes, or both were considered adequate to prevent clinical relapse. In conclusion, we provide consensus-based recommendations aimed at optimizing allo-SCT in PMF. Unmet clinical needs were highlighted.

In current European guidelines for the management of myocardial infarction after coronary stent placement, there is no consensus on dual antiplatelet therapy (DAPT) ideal duration to prevent stent thrombosis-restenosis without significantly increasing the bleeding risk. ⋯ Prolonged use of DAPT would be justified by the high incidence of thrombosis-restenosis, without a significant increase in bleeding risk, as well as a decrease in major cardiovascular events.

Polycythemia vera (PV) is mainly characterized by erythrocytosis, thrombotic and hemorrhagic predisposition, a variety of symptoms, and cumulative risks of fibrotic progression and/or leukemic evolution over time. The diagnosis is made based on the 2016 WHO criteria. The treatment of PV focuses on rapidly reducing the erythrocyte mass, either by means of phlebotomies or with cytoreductive treatment, and the reduction of thrombotic risk by correcting cardiovascular risk factors and the use of platelet antiaggregants.

The population living in conditions of poorness has a heavier pathological burden than social strata with better economic possibilities. ⋯ The evidence generated should lead to decisions aimed at improving the quality of life of the population with social deprivations and vulnerabilities, which needs to be protected against the consequences of current COVID-19 pandemic.

Head and neck cancer patients are at high risk of SARS-CoV-2 infection; surgery in them involves risk for patients, surgeons, health personnel, medical institutions and society, since it is associated with prolonged and inadvertent production of aerosols and emergency procedures that facilitate the breach of protective measures by health personnel. ⋯ Chest tomography is not useful as the only preoperative screening procedure for COVID-19, since its findings are nonspecific, with a high rate of false-positive results. Clinical evaluation, with PCR and tomography, is the best form of preoperative screening.
