Medical education during COVID-19 associated lockdown: Faculty and students' perspective.
The lockdown imposed due to novel coronavirus disease 2019 (COVID-19) has resulted in adopting electronic learning (e-learning) as the means of education in various institutions all over India. This study aimed to collect the experiences of faculty and students regarding e-learning in medical colleges during COVID-19 and to analyse the likely perceived benefits and problems to choose blended learning activities after the COVID crisis. ⋯ Implementation of e-learning within the existing curriculum is bound to be challenging; however, it remains the only solution during COVID-19 imposed lockdown for maintaining the chain of learning.

Maternal and perinatal outcomes of pregnant women with SARS-CoV-2 infection.
To evaluate the maternal and perinatal outcomes of pregnancies affected by SARS-CoV-2 infection. ⋯ SARS-CoV-2 infection in pregnant women is associated with a 0.8% rate of maternal mortality, but an 11.1% rate of admission to the ICU. The risk of vertical transmission seems to be negligible. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

On the concentration of SARS-CoV-2 in outdoor air and the interaction with pre-existing atmospheric particles.
The spread of SARS-CoV-2 by contact (direct or indirect) is widely accepted, but the relative importance of airborne transmission is still controversial. Probability of outdoor airborne transmission depends on several parameters, still rather uncertain: virus-laden aerosol concentrations, viability and lifetime, minimum dose necessary to transmit the disease. In this work, an estimate of outdoor concentrations in northern Italy (region Lombardia) was performed using a simple box model approach, based on an estimate of respiratory emissions, with a specific focus for the cities of Milan and Bergamo (Italy). ⋯ The probability was very low. In addition, the probability of coagulation of virus-laden aerosol with pre-existing atmospheric particles resulted negligible for accumulation and coarse mode particles, but virus-laden aerosol could act as sink of ultrafine particles (around 0.01 μm in diameter). However, this will not change significantly the dynamics behaviour of the virus particle or its permanence time in atmosphere.

It has been suggested that some individuals may present genetic susceptibility to SARS-CoV-2 infection, with particular research interest in variants of the ACE2 and TMPRSS2 genes, involved in viral penetration into cells, in different populations and geographic regions, although insufficient information is currently available. This study addresses the apparently reasonable hypothesis that variants of these genes may modulate viral infectivity, making some individuals more vulnerable than others. Through whole-exome sequencing, the frequency of exonic variants of the ACE2, TMPRSS2, and Furin genes was analyzed in relation to presence or absence of SARS-CoV-2 infection in a familial multiple sclerosis cohort including 120 individuals from Madrid. ⋯ While TMPRSS2 is highly polymorphic, the variants found do not coincide with those described in other studies, with the exception of rs75603675, which may be associated with SARS-CoV-2 infection. The synonymous variants rs61735792 and rs61735794 showed a significant association with infection. Despite the limited number of patients with SARS-CoV-2 infection, some variants, especially in TMPRSS2, may be associated with COVID-19.

The Face of COVID-19: Facial Pressure Wounds Related to Prone Positioning in Patients Undergoing Ventilation in the Intensive Care Unit.
In the setting of COVID-19 (coronavirus disease 2019)-associated moderate and severe acute respiratory distress, persistently hypoxemic patients often require prone positioning for >16 hours. We report facial pressure wounds and ear necrosis as a consequence of prone positioning in patients undergoing ventilation in the intensive care unit in a tertiary medical center in New York City.
