In a Coronavirus disease 2019 (COVID-19) epidemic, management of the emergency department is a difficult task in terms of prevention and control of the disease in general hospitals. On top of meeting urgent needs of patients for medical treatment, the emergency department also has to devote resources into investigation and prevention of COVID-19. ⋯ As of the writing of this manuscript, there has been no active COVID-19 infection in patients and medical staff in the emergency department, and no infection in patients admitted to PKUFH through the emergency department. This study describes the prevention and control measures in the emergency department of PKUFH during the outbreak of COVID-19, aiming to provide some reference for domestic and international medical institutions.

Transplant programs have been severely disrupted by the COVID-19 pandemic. Italy was one of the first countries with the highest number of deaths in the world due to SARS-CoV-2. Here we propose a management model for the reorganization of liver transplant (LT) activities and policies in a local intensive care unit (ICU) assigned to liver transplantation affected by restrictions on mobility and availability of donors and recipients as well as health personnel and beds. ⋯ No differences were found in the provenance area, additional MELD scores, age of donors and recipients, BMI, re-transplant rates, and post-transplant mortality. No transplanted patients contracted COVID-19, although five healthcare workers did. Ultimately, our policy allowed us to continue the ICU's operations by prioritizing patients hospitalized with higher MELD without any case of transplant infection due to COVID-19.

The overflow of studies in the recent literature on COVID-19 often gives provisional or contradictory results and therefore deserves pauses of reflection and reconsideration. In fact, knowledges of pathophysiology of this new disease are still in development and hence originate discussions and interpretations. Regarding the role of blood coagulation and fibrinolysis, these mechanisms should be considered as crucial especially in severe cases. ⋯ This results in widespread occlusive thrombotic micro-angiopathy with destruction of alveoli and obstructive neoangiogenesis. The involvement of fibrinolysis, often neglected, confers a double faceted process of activation/inhibition, finally conducive to a fibrinolytic shutdown that reinforces persistence of micro-thrombi. Considering these peculiar mechanisms, it seems evident that both prophylactic and therapeutic effects of current anti-thrombotic drugs cannot be taken for granted and need therefore new specific and rigorous controlled trials.
