Multicenter Study Comparative Study Observational StudyA tidal volume of 7 mL/kg PBW or higher may be safe for COVID-19 patients.
The novel coronavirus disease (COVID-19) has revived the debate on the optimal tidal volume during acute respiratory distress syndrome (ARDS). Some experts recommend 6 mL/kg of predicted body weight (PBW) for all patients, while others suggest 7-9 mL/kg PBW for those with compliance >50 mL/cmH2O. We investigated whether a tidal volume ≥ 7 ml/kg PBW may be safe in COVID-19 patients, particularly those with compliance >50 mL/cmH2O. ⋯ A tidal volume ≥ 7 (up to 9) mL/kg PBW was associated with lower ICU mortality in these COVID-19 patients, including those with compliance <40 mL/cmH2O. This finding should be interpreted cautiously due to the retrospective study design.

Shock prediction with dipeptidyl peptidase-3 and renin (SPiDeR) in hypoxemic patients with COVID-19.
Plasma dipeptidyl peptidase-3 (DPP3) and renin levels are associated with organ dysfunction and mortality. However, whether these biomarkers are associated with the subsequent onset of shock in at-risk patients is unknown. ⋯ In patients hospitalized with COVID-19 and hypoxemia without baseline hypotension, higher baseline plasma levels of DPP3 but not renin were associated with increased risk of subsequent shock and death.

In the UK, booster COVID-19 vaccinations have been recommended biannually to people considered immune vulnerable. We investigated, at a population level, whether the absence of detectable anti-SARS-CoV-2 spike protein IgG antibody (anti-S Ab) following three or more vaccinations in immunosuppressed individuals was associated with greater risks of infection and severity of infection. ⋯ UK Research and Innovation, Kidney Research UK, Blood Cancer UK, Vasculitis UK, and Cystic Fibrosis Trust.
