Randomized Controlled Trial Comparative Study
Cadaver versus Simulator Based Arthroscopic Training in Shoulder Surgery.
There are few studies that compare the cadaver dissections with the medical simulators in means of talent improvement. Therefore, the aim of this study is to find out if using cadaver dissections is still the golden standard for surgical training or using the medical simulators in surgery could replace cadaver dissections. ⋯ To the best of our knowledge, this study is the first one to compare virtual reality (VR) simulators with cadavers for surgical education in an objective manner, while using qualitative and quantitative data. According to this study, it is possible to state that VR simulators are just as effective as cadavers in means of training subjects. As medical education will face a total change all around the world after the COVID-19 pandemic, this study has the potential to be an important guide during and after this period.

SARS-CoV-2 infects the respiratory tract and leads to the disease entity, COVID-19. Accordingly, the lungs bear the greatest pathologic burden with the major cause of death being respiratory failure. However, organs remote from the initial site of infection (e.g., kidney, heart) are not spared, particularly in severe and fatal cases. ⋯ A common finding in autopsy specimens is the presence of thrombi in the lungs as well as remote organs, indicative of immunothrombosis. Herein, the role of SARS-CoV-2 in lung inflammation and associated sequelae are reviewed with an emphasis on immunothrombosis. In as much as vitamin D is touted as a supplement to conventional therapies of COVID-19, the impact of this vitamin at various junctures of COVID-19 pathogenesis is also addressed.

The aim of this descriptive article is to share the experience in Ege University, Turkey with favipiravir in the treatment of severe SARS-CoV-2 pneumonia. ⋯ This study provides relevant information for the treatment of COVID-19, suggesting that favipiravir was associated with significant clinical and laboratory improvements in the majority of the patients, is a safe drug with no serious side effects and would merit further investigation.

Viruses are the most common pathogens that can cause infection-related non-recurrent death after transplantation, occurring mostly from the early stages of hematopoietic stem cell transplantation (HSCT) to within 1 year after transplantation. Human coronavirus (HCoV)-NL63 is a coronavirus that could cause mortality among patients with underlying disease complications. Serological tests are of limited diagnostic value in immunocompromised hosts and cases of latent infection reactivation. In contrast, macro-genomic high-throughput (DNA and RNA) sequencing allows for rapid and accurate diagnosis of infecting pathogens for targeted treatment. ⋯ The latest NGS is an effective method for early infection diagnosis. The HCoV-NL63 virus can cause inflammatory factor storm and alter the neutrophil-to-lymphocyte ratio (NLR). This case suggests that the patient's NLR and cytokine levels could be monitored during the clinical treatment to assess the disease and its treatment outcome in a timely manner.

Correlation of SARS-CoV-2 RNA in wastewater with COVID-19 disease burden in sewersheds.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the coronavirus disease (COVID-19), is shed in feces and the viral ribonucleic acid (RNA) is detectable in wastewater. A nine-week wastewater epidemiology study of ten wastewater facilities, serving 39% of the state of Utah or 1.26 M individuals was conducted in April and May of 2020. COVID-19 cases were tabulated from within each sewershed boundary. ⋯ SARS-CoV-2 RNA followed a first order decay rate in wastewater, while 90% of the RNA was present in the liquid phase of the influent. Infiltration and inflow, virus decay and sewershed characteristics should be considered during correlation analysis of SAR-CoV-2 with COVID-19 cases. These results provide evidence of the utility of wastewater epidemiology to assist in public health responses to COVID-19.
