Acute hypoxemic respiratory failure (HRF) is associated with high morbidity and mortality, but its heterogeneity challenges the identification of effective therapies. Defining subphenotypes with distinct prognoses or biologic features can improve therapeutic trials, but prior work has focused on ARDS, which excludes many acute HRF patients. We aimed to characterize persistent and resolving subphenotypes in the broader HRF population. ⋯ Patients with persistent HRF are common and have higher mortality and elevated circulating markers of lung injury compared to resolving HRF, and yet only a subset are captured by ARDS definitions. Persistent HRF may represent a clinically important, inclusive target for future therapeutic trials in HRF.

Multicenter Study Observational Study
The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients.
Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. ⋯ Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation.

Objective: To investigate the rate of interhospital emergency transport for bronchiolitis and intensive care admission following the introduction of high flow nasal cannula and standardised paediatric observation and response charts. Design: Retrospective cohort study. Setting: A statewide paediatric intensive care transport service and its two referral paediatric intensive care units (PICUs) in Victoria, Australia. ⋯ The proportion of mechanical ventilation as well as PICU and hospital length of stay decreased over time. Conclusions: The population-adjusted rate of interhospital transport and admission to the PICU for bronchiolitis increased over time. This occurred despite a lower rate of non-invasive and invasive mechanical ventilation during transport and in the PICU.

Dexmedetomidine and Mortality From Sepsis Requiring Mechanical Ventilation: A Japanese Nationwide Retrospective Cohort Study.
Dexmedetomidine has a mild sedative effect and may reduce mortality in mechanically ventilated critically ill patients. However, few studies have examined the effects of dexmedetomidine in patients with sepsis who require mechanical ventilation. The aim of this study was to investigate the association between dexmedetomidine and mortality in patients with sepsis requiring mechanical ventilation, using a nationwide inpatient database in Japan. ⋯ Dexmedetomidine was associated with a reduction in all-cause 28-day mortality and duration of mechanical ventilation.

Selective digestive decontamination (SDD) regimens, variously constituted with topical antibiotic prophylaxis (TAP) and protocolized parenteral antibiotic prophylaxis (PPAP), appear highly effective for preventing ICU-acquired infections but only within randomized concurrent control trials (RCCT's). Confusingly, SDD is also a concept which, if true, implies population benefit. The SDD concept can finally be reified in humans using the broad accumulated evidence base, including studies of TAP and PPAP that used non-concurrent controls (NCC), as a natural experiment. However, this test implicates overall population harm with higher event rates associated with SDD use within the ICU context.
