Randomized Controlled Trial
Morphine and hydromorphone pharmacokinetics in human volunteers: population-based modelling of interindividual and opioid-related variability.
Morphine and hydromorphone have differing onsets, magnitudes, and durations of effects and side-effects. Differences between opioids in their interindividual variabilities in pharmacokinetics and pharmacodynamics might influence rational drug selection. Crossover drug studies can provide more informative interindividual variability data than parallel group studies. Using data from a crossover study of i.v. morphine and hydromorphone in healthy volunteers, we tested the hypothesis that morphine and hydromorphone differ in their interindividual pharmacokinetic variability. ⋯ Morphine and hydromorphone did not differ in a statistically significant or clinically meaningful manner in their interindividual pharmacokinetic variability. Interindividual pharmacokinetic variability does not appear a meaningful consideration in the choice between these two opioids.

Randomized Controlled Trial Multicenter Study
Early noninvasive ventilation in general wards for acute respiratory failure: an international, multicentre, open-label, randomised trial.
The impact of noninvasive ventilation (NIV) managed outside the intensive care unit in patients with early acute respiratory failure remains unclear. We aimed to determine whether adding early NIV prevents the progression to severe respiratory failure. ⋯ NCT01572337.

Randomized Controlled Trial
Effect of exercise prehabilitation on quality of recovery after cardiac surgery: a single-centre randomised controlled trial.
Physical prehabilitation can enhance patient resilience to surgical stress, but its effects are unclear in vulnerable and frail patients. We aimed to determine the effect of a structured exercise prehabilitation programme on the quality of recovery after cardiac surgery in vulnerable and frail participants. ⋯ ChiCTR1800016098.

Randomized Controlled Trial
Phase 1 single-centre placebo- and etomidate-controlled study in healthy volunteers to assess safety, tolerability, clinical effects, and pharmacokinetics of intravenous methoxyethyl etomidate hydrochloride (ET-26).
Methoxyethyl etomidate hydrochloride (ET-26) is a novel etomidate analogue. This is the first-in-human study of a bolus i.v. formulation of ET-26 to assess its safety, tolerability, hypnotic effects, and pharmacokinetics. ⋯ ChiCTR2100047525 (https://www.chictr.org.cn/index.aspx, ChiCTR2100047525).

Randomized Controlled Trial Multicenter Study
The effect of high protein dosing in critically ill patients: an exploratory, secondary Bayesian analyses of the EFFORT Protein trial.
The EFFORT Protein trial assessed the effect of high vs usual dosing of protein in adult ICU patients with organ failure. This study provides a probabilistic interpretation and evaluates heterogeneity in treatment effects (HTE). ⋯ We found moderate to high probabilities of harm with high protein doses compared with usual protein in ICU patients for the primary and secondary outcomes. We found suggestions of heterogeneity in treatment effects with worse outcomes in participants randomised to high protein doses with renal dysfunction or acute kidney injury and greater illness severity at baseline.
