The recent outbreak of coronavirus disease (COVID-19) caused by SARS-CoV-2 infection in Wuhan, China has posed a serious threat to global public health. To develop specific anti-coronavirus therapeutics and prophylactics, the molecular mechanism that underlies viral infection must first be defined. Therefore, we herein established a SARS-CoV-2 spike (S) protein-mediated cell-cell fusion assay and found that SARS-CoV-2 showed a superior plasma membrane fusion capacity compared to that of SARS-CoV. ⋯ Here we generated a series of lipopeptides derived from EK1 and found that EK1C4 was the most potent fusion inhibitor against SARS-CoV-2 S protein-mediated membrane fusion and pseudovirus infection with IC50s of 1.3 and 15.8 nM, about 241- and 149-fold more potent than the original EK1 peptide, respectively. EK1C4 was also highly effective against membrane fusion and infection of other human coronavirus pseudoviruses tested, including SARS-CoV and MERS-CoV, as well as SARSr-CoVs, and potently inhibited the replication of 5 live human coronaviruses examined, including SARS-CoV-2. Intranasal application of EK1C4 before or after challenge with HCoV-OC43 protected mice from infection, suggesting that EK1C4 could be used for prevention and treatment of infection by the currently circulating SARS-CoV-2 and other emerging SARSr-CoVs.

A position statement published by the Italian Society of Anesthesia Analgesia Resuscitation and Intensive Care (SIAARTI) is fostering a vibrant debate, crossed by deep fears. These are recommendations addressed to ICU doctors who must decide whether to implement intensive treatments for patients who need them to survive. Specifically, the reference is to the patients to whom the CoViD-19 epidemic has compromised respiratory capacity. We still do not have clear what positive criteria can help make clinical decisions in contexts of insufficient resources that force us to make choices.

COVID-19 was first identified in Iran in February 2020 and since then it spread rapidly through all over the country and soon after that it was reported as a pandemic. The current study presents a preliminary report of spine trauma management during COVID-19 pandemic. ⋯ Proper diagnosis of COVID-19 is the keystone to protect both patients and health care providers. During the pandemic all admitted patients should be screened for COVID-19 infection. Unnecessary procedures for spine trauma patients should be avoided in order to reduce complications related to surgery and to preserve ICU beds.

[Analysis of the clinical characteristics and early warning model construction of severe/critical coronavirus disease 2019 patients].
To analyze the clinical characteristics of critical patients with coronavirus disease 2019 (COVID-19), build an early warning model for severe/critical type, and aim at providing reference for the prediction of severe/critical COVID-19. ⋯ There are many differences between severe/critical and mild COVID-19 patients. The establishment of early warning model could help to screen severe/critical patients at an early stage, with certain significance for guiding treatment.
