Large study finds higher burden of acute brain dysfunction for COVID-19 ICU patients

COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. Choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients.

Study suggests new threshold for diagnosing PAH

Doctors diagnosing pulmonary arterial hypertension (PAH) — elevated pulmonary pressure due to an issue in the small vessels of the lung — rely on a hemodynamic threshold set in the early 1970s to determine whether patients would be candidates for pulmonary vasodilator therapy.
