COVID-19 Aerosol Transmission Calculator – Customized

By |2020-07-25T17:52:01+00:00July 25th, 2020|

INTRODUCTION  This calculator determines the number of new COVID-19 infections in a space (classroom, etc.) due to aerosol transmission, accounting for infectious aerosol in the breath of asymptomatic individuals.

Change in the Incidence of Stillbirth and Preterm Delivery During the COVID-19 Pandemic

By |2020-07-25T17:51:52+00:00July 25th, 2020|

High rates of preterm birth and cesarean delivery have been reported in women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.1 However, studies have inadequate power to assess uncommon outcomes like stillbirth (fetal death ≥24 weeks’ gestation). The UK Obstetric Surveillance System reported 3 stillbirths among 247 completed pregnancies in women with confirmed coronavirus disease [...]

Immunophenotyping of COVID-19 and influenza highlights the role of type I interferons in development of severe COVID-19

By |2020-07-25T17:51:51+00:00July 25th, 2020|

Abstract Although most SARS-CoV-2-infected individuals experience mild coronavirus disease 2019 (COVID-19), some patients suffer from severe COVID-19, which is accompanied by acute respiratory distress syndrome and systemic inflammation. To identify factors driving severe progression of COVID-19, we performed single-cell RNA-seq using peripheral blood mononuclear cells (PBMCs) obtained from healthy donors, patients with mild or severe COVID-19, [...]

Rheumatoid arthritis drug tied to fewer deaths in COVID patients

By |2020-07-25T17:51:49+00:00July 25th, 2020|

Two new studies have revealed that the rheumatoid arthritis drug tocilizumab is associated with lower death rates in COVID-19 patients receiving mechanical ventilation. Tocilizumab blocks interleukin-6 (IL-6), an inflammatory protein involved in a potential “cytokine storm” that can lead to respiratory failure in coronavirus patients. In the first single-center observational study, published late last week in Clinical Infectious [...]

Canadian Antimicrobial System Report

By |2020-07-25T17:51:46+00:00July 25th, 2020|

Antimicrobials are important medical therapies that have come to define modern medicine. Their unnecessary use and overuse can promote the emergence of antimicrobial resistance (AMR) – that is, the ability of organisms to overcome the effects of the drugs designed to kill them. The spread of antimicrobial-resistant organisms (AROs), sometimes referred to as superbugs, jeopardizes [...]

Total daily steps, not step intensity, offer more benefits

By |2020-07-25T16:53:07+00:00July 25th, 2020|

Don’t be discouraged if you’re not a quick walker. A new study suggests that total daily steps — and not how many steps you take per minute — are related to a lower risk of death. The results were published in the March 24/31, 2020, issue of JAMA. Researchers examined data from 4,840 people, average age 57, [...]
