After severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia, patients may show lung sequelae on radiology and functional impairment at the 1-year follow-up. We aimed to describe the persistence of symptoms, radiological alterations, or reduced diffusing capacity of the lung for carbon monoxide (DLCO ) at 1-year follow-up in patients from the Spanish Registry RECOVID. ⋯ The factors associated with symptom persistence, incomplete radiological resolution and DLCO <80% differed according to age, sex, comorbidities and respiratory support. The burden of symptoms, reduced DLCO and incomplete radiological resolution were considerable in patients with SARS-CoV-2 pneumonia at the 1-year follow-up after hospitalisation.

Observational StudyEchocardiography Before Extracorporeal Membrane Oxygenation in Refractory Respiratory Failure: SARS-CoV-2 Infection Versus Other Etiologies.
The study authors hypothesized that in patients with SARS-CoV-2, COVID-19-related refractory respiratory failure requiring extracorporeal membrane oxygenation (ECMO) support echocardiographic findings (just before ECMO implantation) would be different from those observed in patients with refractory respiratory failure from different etiologies. ⋯ The presence of RV dilatation and an altered coupling between RVe function and pulmonary vasculature (as indicated by TAPSE and/or sPAP) are associated strictly with COVID-19-related refractory respiratory failure needing ECMO support.
