Emerging clinical trial data suggest that individual immunomodulatory drugs can dampen the hyperactive immune system in severe COVID-19, but polytherapy is the way forward.
On June 5 the Ministry of Health of the Russian Federation registered Biocad’s Ilsira (levilimab) as a treatment for severe COVID-19. Ilsira is one of several monoclonal antibodies (mAbs) targeting interleukin-6 receptor (IL-6R) and a host of other inflammatory cytokines currently in clinical testing against coronavirus...

Abstract
Stringent COVID-19 control measures were imposed in Wuhan between January 23 and April 8, 2020. Estimates of the prevalence of infection following the release of restrictions could inform post-lockdown pandemic management. Here, we describe a city-wide SARS-CoV-2 nucleic acid screening programme between May 14 and June 1, 2020 in Wuhan. All city residents aged six years or older were eligible and 9,899,828 (92.9%) participated. No new symptomatic cases and 300 asymptomatic cases (...

Background
Previous studies have indicated Coronavirus disease 2019 (COVID-19) patients with cancer have a high fatality rate.
Methods
We conducted a systematic review of studies that reported fatalities in COVID-19 patients with cancer. A comprehensive meta-analysis that assessed the overall case fatality rate and associated risk factors was performed. Using individual patient data, univariate and multivariate logistic regression analyses were used to estimate odds ratios (OR) for e...

Abstract
Background: Prior to the COVID-19 pandemic, urology was one of the specialties with the lowest rates of telemedicine and videoconferencing use. Common barriers to the implementation of telemedicine included a lack of technological literacy, concerns with reimbursement, and resistance to changes in the workplace. In response to the COVID-19 pandemic declared in March 2020, the delivery of urological services globally has quickly shifted to telemedicine to account for the mass ...

Abstract
Coronavirus disease-2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The infection is spreading globally and poses a huge threat to human health. Besides common respiratory symptoms, some patients with COVID-19 experience gastrointestinal symptoms, such as diarrhea, nausea, vomiting, and loss of appetite. SARS-CoV-2 might infect the gastrointestinal tract through its viral receptor angiotensin-converting enzyme 2 (ACE2) and there is increa...

Key Points
Question Does early tocilizumab administration prevent clinical worsening in patients hospitalized with coronavirus disease 2019 (COVID-19) pneumonia?

Findings In this randomized clinical trial of 126 patients with a partial pressure of arterial oxygen to fraction of inspired oxygen (Pao2/Fio2) ratio between 200 and 300 mm Hg at enrollment, the rate of the primary clinical end point (clinical worsening) was not significantly different between the control group a...

The coronavirus disease 2019 (COVID-19) pandemic has caused significant disruptions to education for surgical residents across the country. Residents have experienced reduced operative exposure, decreased time caring for hospitalized patients, and altered rotation schedules. A number of studies have been published since the start of the COVID-19 pandemic regarding the effect of the crisis on residents and resident education across fields including internal medicine, emergency medicine, o...

Abstract
The individual infectiousness of coronavirus disease 2019 (COVID-19), quantified by the number of secondary cases of a typical index case, is conventionally modelled by a negative-binomial (NB) distribution. Based on patient data of 9120 confirmed cases in China, we calculated the variation of the individual infectiousness, i.e., the dispersion parameter k of the NB distribution, at 0.70 (95% confidence interval: 0.59, 0.98). This suggests that the dispersion in the indi...

AbstractThe coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is still wreaking havoc in many parts of the world and poses a great burden to healthcare systems worldwide. Mitigation and suppression strategies have been implemented globally but the disease has proven to be difficult to contain. Initially many elective gastrointestinal (GI) endoscopies were cancelled to reduce the risk of infection and conserve personal protective e...

Abstract
This study used a national administrative database to estimate perioperative SARS‐CoV‐2 infection risk, and associated mortality, relative to nosocomial transmission rates. The impact of nosocomial transmission was greatest after major emergency surgery, whereas laparoscopic surgery may be protective owing to reduced duration of hospital stay. Procedure‐specific risk estimates are provided to facilitate surgical decision‐making and informed consent.

Abstract
This online structured survey has demonstrated the global impact of the COVID‐19 pandemic on vascular services. The majority of centres have documented marked reductions in operating and services provided to vascular patients. In the months during recovery from the resource restrictions imposed during the pandemic peaks, there will be a significant vascular disease burden awaiting surgeons.
