Editorial Comment
Silver linings: will the COVID-19 pandemic instigate long overdue mental health support services for healthcare workers?
A study in this month's journal adds to the growing body of evidence regarding the potential mental health impacts on frontline healthcare staff working during the COVID-19 pandemic. As clinical academics representing critical care, nursing, and medicine, and a psychologist guiding support for frontline health and social workers, we offer our perspectives on this study. We discuss the balance between pragmatic and rigorous data collection on this topic and offer perspectives on the observed differential impact on nurses. Finally, we suggest that the pandemic might have a positive effect by instigating more robust mental health support services for National Health Service workers.

Review Meta Analysis
Measurement of quality of recovery after surgery using the 15-item quality of recovery scale: a systematic review and meta-analysis.
There are very few patient-centred global outcome measures of recovery in the days or weeks after surgery. This meta-analysis evaluated the psychometric properties and clinical acceptability of the 15-item quality of recovery (QoR-15) scale. ⋯ Open Science Framework Identifier: DOI 10.17605/OSF.IO/78HTA.

Perioperative hypotension is common and associated with poor outcomes, including acute kidney injury (AKI). The mechanistic link between perioperative hypotension and AKI is at least partly a consequence of the susceptibility of the kidney, and particularly the renal medulla, to ischaemia and hypoxia. Several critical gaps in our knowledge lead to uncertainty about when and how to intervene to prevent AKI attributable to perioperative hypotension. ⋯ Third, there is little information regarding the relative risks and benefits of various clinically available therapies (e.g. vasoconstrictors, i.v. fluids, or both) to treat and prevent perioperative hypotension, particularly with regard to renal medullary perfusion and oxygenation. Fourth, there are currently no validated, clinically feasible methods for real-time clinical monitoring of renal perfusion or oxygenation. Thus, future developments in perioperative kidney-protective strategies must rely on the development of methods to better monitor renal perfusion and oxygenation in the perioperative period, and thereby guide timing, intensity, type, and duration of interventions.

High intraoperative PEEP with recruitment manoeuvres may improve perioperative outcomes. We re-examined this question by conducting a patient-level meta-analysis of three clinical trials in adult patients at increased risk for postoperative pulmonary complications who underwent non-cardiothoracic and non-neurological surgery. ⋯ NCT03937375 (Clinicaltrials.gov).
