On March 11, 2020, the World Health Organization (WHO) stated that the number of cases of COVID-19 multiplied by 13 outside China, with a threefold increase in the number of affected countries. The WHO expressed its concern about the alarming levels of spread and severity of the outbreak, declaring the pandemic. This pandemic context is generating a social pact that seeks to ensure collective protection over individual freedoms. To meet the challenge, Governments must make decisions based on the principles that govern the State- These should consider the differences and particularities of those affected, without diverting attention from collective social protection. The following is a proposal on the ethical principles that should guide a State that makes decisions in public health emergencies.Von Willebrand factor (vWf) is a fundamental multimeric plasma glycoprotein in the coagulation process. Its function is to mediate platelet adhesion and to stabilize circulating factor VIII. A functional or quantitative alteration of vWf gives rise to von Willebrand disease (vWD). The association between vWD and angiodysplasia was described in 1967, but it was only until 2011 that Starke et al demonstrated the in vitro and in vivo role of vWf in angiogenesis. Congenital or acquired vWf deficiency, especially of high molecular weight multimeters, not only favors bleeding, but also contributes to increased angiogenesis in these patients. The treatment should be focused both on the control of the acute episode of gastrointestinal bleeding, with vWf replacement therapy and local endoscopic treatment, as well as on the prevention of the progression of angiodysplasia and future bleeding. There are different published therapeutic approaches using vWf replacement that are not effective in all patients. Recently, angiogenesis inhibitor medications have been used.Coronavirus disease 19 is characterized by an intense inflammatory response and a high incidence of thrombotic events. Autopsy studies show severe endothelial injury associated with thrombosis of the alveolar capillaries of the lungs and other organs. iCRT3 mw In the pathophysiology of this disease endothelial injury and dysfunction, inflammation and thrombosis are key factors for the development of severe phenotypes. Therefore, we should consider this entity as a systemic endothelial disease in which an obstructive microvascular syndrome secondary to an intense thrombo-inflammatory response leads to acute respiratory insufficiency and multiorgan failure. Heparin is an excellent drug to treat Covid-19 patients due to its anticoagulant, anti-inflammatory, antiviral and endothelial effects. Clinical guidelines agree that the use of heparin thromboprophylaxis is a component of Covid-19 coagulopathy treatment, even though the dose and duration of treatments are not well defined. The suspension of face-to-face teaching activity due to the COVID-19 pandemic forced an abrupt transition to distance learning in Spanish universities. To know how medical students value distance learning in the context of COVID-19 pandemic. Undergraduate medical students from first to fifth year in Barcelona (Spain) were invited to answer an anonymous online survey about their perceptions and level of satisfaction with virtual learning. Of 483 students invited to the survey, 244 (50.5%) answered it. Respondents from the first and second year rated distance learning as acceptable (mean 3.1) on a Likert scale from 1 to 5. Those from third to fifth years rated distance learning as unsatisfactory (mean 2.7). The best evaluated aspects were synchronous lectures (3.9) and lectures based on cases (3.4). The worst evaluated issues were motivation (2.3), interaction with faculty (2.1), and additional workload (0.7). The perceptions expressed by these students reinforce the importance of facilitating communication, motivation and participation of students in distance le
