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.

An Intensive Care Unit Team Reflects on End-of-Life Experiences With Patients and Families in Chile.
Deaths in the intensive care unit (ICU) represent an experience of suffering for patients, their families, and professionals. End-of-life (EOL) care has been added to the responsibilities of the ICU team, but the evidence supporting EOL care is scarce, and there are many barriers to implementing the clinical recommendations that do exist. ⋯ These qualitative findings expose gaps in care that must be filled to achieve high-quality EOL care in the ICU. Significant emotional impact, barriers related to EOL decision-making, limited interprofessional clinical practice, and communication difficulties were the main findings cross-referenced.
