Background Elevated proinflammatory cytokines are associated with greater COVID-19 severity. We aimed to assess safety and efficacy of sarilumab, an interleukin-6 receptor inhibitor, in patients with severe (requiring supplemental oxygen by nasal cannula or face mask) or critical (requiring greater supplemental oxygen, mechanical ventilation, or extracorporeal support) COVID-19. Methods We did a 60-day, randomised, double-blind, placebo-controlled, multinational phase 3 trial at 45 hospitals in Argentina, Brazil, Canada, Chile, France, Germany, Israel, Italy, Japan, Russia, and Spain. We included adults (≥18 years) admitted to hospital with laboratory-confirmed SARS-CoV-2 infection and pneumonia, who required oxygen supplementation or intensive care. Patients were randomly assigned (2:2:1 with permuted blocks of five) to receive intravenous sarilumab 400 mg, sarilumab 200 mg, or placebo. Patients, care providers, outcome assessors, and investigators remained masked to assigned intervention throughout the course of the study. The primary endpoint was time to clinical improvement of two or more points (seven point scale ranging from 1 [death] to 7 [discharged from hospital]) in the modified intention-to-treat population. The key secondary endpoint was proportion of patients alive at day 29. Safety outcomes included adverse events and laboratory assessments. This study is registered with ClinicalTrials.gov , NCT04327388 ; EudraCT, 2020-001162-12; and WHO, U1111-1249-6021. Findings Between March 28 and July 3, 2020, of 431 patients who were screened, 420 patients were randomly assigned and 416 received placebo (n=84 [20%]), sarilumab 200 mg (n=159 [38%]), or sarilumab 400 mg (n=173 [42%]). At day 29, no significant differences were seen in median time to an improvement of two or more points between placebo (12·0 days [95% CI 9·0 to 15·0]) and sarilumab 200 mg (10·0 days [9·0 to 12·0]; hazard ratio [HR] 1·03 [95% CI 0·75 to 1·40]; log-rank p=0·96) or sarilumab 400 mg (10·0 days [9·0 to 13·0]; HR 1·14 [95% CI 0·84 to 1·54]; log-rank p=0·34), or in proportions of patients alive (77 [92%] of 84 patients in the placebo group; 143 [90%] of 159 patients in the sarilumab 200 mg group; difference −1·7 [−9·3 to 5·8]; p=0·63 vs placebo; and 159 [92%] of 173 patients in the sarilumab 400 mg group; difference 0·2 [−6·9 to 7·4]; p=0·85 vs placebo). At day 29, there were numerical, non-significant survival differences between sarilumab 400 mg (88%) and placebo (79%; difference +8·9% [95% CI −7·7 to 25·5]; p=0·25) for patients who had critical disease. No unexpected safety signals were seen. The rates of treatment-emergent adverse events were 65% (55 of 84) in the placebo group, 65% (103 of 159) in the sarilumab 200 mg group, and 70% (121 of 173) in the sarilumab 400 mg group, and of those leading to death 11% (nine of 84) were in the placebo group, 1...

A patient transferred from South Africa to Israel acquired a Candida auris infection. Phylogenetic analysis showed resemblance of C. auris to isolates from South Africa but not Israel, suggesting travel-associated infection. C. auris infection occurred weeks later in another patient at the same hospital, suggesting prolonged environmental persistence.

A 6-plex protein array presenting the whole inactivated virus and five nucleocapsid and spike-derived SARS-CoV-2 antigens was used to generate a serological snapshot of SARS-CoV-2 seroprevalence and seroconversion in Israel in the early months of the pandemic. Our findings confirm a very low seroprevalence of anti-SARS-CoV-2 antibodies in the Israeli adult population.

Objective: To assess reasons for noncompliance to COVID-19 vaccination among health care workers. Design: Cohort observational and surveillance study. Setting: Sheba Medical center, a 1600 bed tertiary medical center in Israel Participants: 10,888 Health care workers including all employees, students and volunteers. Intervention: The BNT162b2 mRNA Covid-19 vaccine was offered to all health care workers of the hospital, non-compliance was assessed and pre-rollout and post-rollout surveys were carried out. Data regarding uptake of the vaccine as well as demographic data and compliance to prior influenza vaccination was collected. Additionally, two surveys were distributed; pre-rollout, regarding intention to receive the vaccine and post-rollout, to all unvaccinated health care workers regarding causes of hesitancy. Results: In the pre-rollout survey 1673/3563 (47%) declared their intent to receive the vaccine. Eventually 8108 (79%) of health care workers received the COVID-19 vaccine within 40 days of rollout. In a multivariate logistic regression model, the factors that were significant predictors of vaccine uptake were male gender, 40-59 age group, Paramedical and Doctors, a high socioeconomic level and compliance with flu vaccine. Among 425 unvaccinated health care workers who answered the second survey, the most common cause for hesitancy was the risk during pregnancy (31%). Conclusion: Though vaccine uptake among health care workers was higher than expected, still relatively low uptake was observed among young women and those from lower socioeconomic level and educational background. Concerns regarding vaccine safety during pregnancy were common and more data about vaccine safety especially during pregnancy might improve compliance.

An isolate of unknown identity that had been identified as causing eumycetoma was retained in an international culture collection, and eventually became the nomenclatural type isolate of the rarely encountered Phaeoacremonium sphinctrophorum . The case featured an indurated, painless, swollen lesion on the dorsum of the foot that had developed in a Canadian resident who had previously been a farmer in Laos. Resection alone was curative.
