Multicenter Study
Interpretable machine learning model for new-onset atrial fibrillation prediction in critically ill patients: a multi-center study.
New-onset atrial fibrillation (NOAF) is the most common arrhythmia in critically ill patients admitted to intensive care and is associated with poor prognosis and disease burden. Identifying high-risk individuals early is crucial. This study aims to create and validate a NOAF prediction model for critically ill patients using machine learning (ML). ⋯ We developed a ML model to predict the risk of NOAF in critically ill patients without cardiac surgery and validated its potential as a clinically reliable tool. SHAP improves the interpretability of the model, enables clinicians to better understand the causes of NOAF, helps clinicians to prevent it in advance and improves patient outcomes.

Multicenter StudyOutcomes in Critically Ill Allogeneic Hematopoietic Stem-Cell Transplantation Recipients.
Rationale: Allogeneic hematopoietic stem-cell transplantation (Allo-HSCT) recipients are still believed to be poor candidates for ICU management. Methods: We investigated outcomes and determinants of mortality in a large multicenter retrospective cohort of Allo-HSCT patients admitted between January 1, 2015, and December 31, 2020, to 14 French ICUs. The primary endpoint was 90-day mortality. ⋯ In patients requiring mechanical ventilation, mortality rates ranged from 39% (no other risk factors for mortality) to 100% (four associated risk factors for mortality). Conclusions: Most critically ill Allo-HSCT recipients survive their ICU stays, including those requiring mechanical ventilation, with an overall 90-day survival rate reaching 51.8%. A careful assessment of goals of care is required in patients with two or more risk factors for mortality.

Multicenter Study
Derivation and validation of generalized sepsis-induced acute respiratory failure phenotypes among critically ill patients: a retrospective study.
Septic patients who develop acute respiratory failure (ARF) requiring mechanical ventilation represent a heterogenous subgroup of critically ill patients with widely variable clinical characteristics. Identifying distinct phenotypes of these patients may reveal insights about the broader heterogeneity in the clinical course of sepsis, considering multi-organ dynamics. We aimed to derive novel phenotypes of sepsis-induced ARF using observational clinical data and investigate the generalizability of the derived phenotypes. ⋯ The phenotypes demonstrated unique patterns of organ injury and differences in clinical outcomes, which may help inform future research and clinical trial design for tailored management strategies.

Randomized Controlled Trial Multicenter StudyImpact of withholding early parenteral nutrition on 2-year mortality and functional outcome in critically ill adults.
In critically ill adults, withholding parenteral nutrition until 1 week after intensive care admission (Late-PN) facilitated recovery as compared with early supplementation of insufficient enteral nutrition with parenteral nutrition (Early-PN). However, the impact on long-term mortality and functional outcome, in relation to the estimated nutritional risk, remains unclear. ⋯ Late-PN did not alter 2-year survival and physical functioning in adult critically ill patients, independent of anticipated nutritional risk.

Randomized Controlled Trial Multicenter Study
Characterizing usual-care physical rehabilitation in Canadian intensive care unit patients: a secondary analysis of the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength pilot randomized controlled trial.
Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies. The primary objective of the present study was to describe the usual-care PR received by critically ill patients enrolled in the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength (CYCLE) pilot randomized controlled trial (RCT) of PR. Other objectives were to help contextualize current research and provide data for international comparison. ⋯ ClinicalTrials.gov ( NCT02377830 ); first posted 4 March 2015.
