Insights into Fibrinogen-Mediated COVID-19 Hypercoagubility in Critically Ill Patients.
Coronavirus disease-2019 (COVID-19) is associated with hypercoagulability that may cause thromobembolic complications. We describe our recent studies investigating the mechanisms of hypercoagulability in patients with severe COVID-19 requiring mechanical ventilation during the COVID-19 crisis in New York City in spring 2020. Using rotational thombelastometry we found that almost all patients with severe COVID-19 had signs of hypercoagulability compared with non-COVID-19 controls. ⋯ Fibrinogen, tissue plasminogen activator and plasminogen activator inhibitor-1, but not plasminogen levels were elevated in patients with severe COVID-19. Our studies indicate that hypercoagulability in COVID-19 may be because of decreased fibrinolysis resulting from inhibition of plasmin through high levels of plasminogen activator inhibitor-1. Clinicians creating treatment protocols for anticoagulation in critically ill COVID-19 patients should consider these potential mechanisms of hypercoaguability.

The coronavirus disease (COVID)-19 pandemic has been an enormous global health burden, resulting in hundreds of millions of documented infections and more than 3 million deaths. Increasing reports characterizing the effects of COVID-19 in pediatric populations have been published during the course of the pandemic. We performed a systematic review to assess the scope of diagnosis, treatment, and management of COVID-19 in pediatric patients. ⋯ Pediatric COVID-19 infection is mild and frequently asymptomatic. There is a low risk of severe illness or death in children who contract COVID-19. High-quality studies should be conducted to develop best practices for prevention, diagnosis, and management of symptomatic illness.

Columbia University's Papper Symposium, a virtual event held on March 20, 2021, was dedicated to the coronavirus disease-2019 (COVID-19) pandemic. This article summarizes a lecture by Dr. Roberta Hines, Nicholas M. ⋯ Trainees working on the frontlines may be at particularly high risk for these mental health disorders and are less likely to access resources available to them. Program directors and hospital graduate medical education leaders should be aware of the threats to physiological and psychological safety and take action to prevent further detrimental effects. The rates of burnout and mental health disorders among trainees are expected to rise as a result of the pandemic, making screening programs and increased access to mental health treatment an essential feature of all residency and fellowship programs.
