Meta AnalysisFixed- Versus Variable-Dose Prothrombin Complex Concentrate for the Emergent Reversal of Vitamin K Antagonists: A Systematic Review and Meta-Analysis.
Four-factor prothrombin complex concentrate (4-PCC) is recommended for rapid reversal of vitamin K antagonists (VKAs) such as warfarin, yet optimal dosing remains uncertain. ⋯ A fixed-dose regimen for 4-PCC administration provides benefits over a variable-dose regimen in terms of dose reduction, faster administration time, improved clinical hemostasis, and reduced mortality and thromboembolic events. Further studies are warranted to better refine the optimal fixed-dose regimen.

ReviewTreatment Fidelity in 94 Randomized Controlled Trials of Physical Rehabilitation in the ICU: A Scoping Review.
Recent reviews demonstrated discordant effects of ICU-based physical rehabilitation on physical function. These inconsistencies may be related to differences in treatment fidelity-the extent to which a protocol is delivered as planned. Before evaluating the association of fidelity with outcomes, we must first understand the extent of treatment fidelity reporting in ICU-based physical rehabilitation randomized controlled trials (RCTs). ⋯ Only 19% of treatment fidelity components were reported across studies, with comparator groups more poorly reported. Future research could investigate ways to optimize treatment fidelity reporting and determine characteristics associated with treatment fidelity conduct in ICU-based physical rehabilitation RCTs.

Randomized Controlled Trial Multicenter StudyDeterminants of Subjective Mental and Functional Health of Critical Illness Survivors: Comparing Pre-ICU and Post-ICU Status.
To compare ICU survivors' subjective mental and functional health before ICU admission and after discharge and to assess determinants of subjective health decline or improvement. ⋯ The majority of ICU survivors did not experience substantial changes in their subjective health status, but patients with long ICU stays were prone to subjective mental and functional health decline. Hence, post-ICU care in post-ICU clinics could focus on these patients.

Flow-Limited and Reverse-Triggered Ventilator Dyssynchrony Are Associated With Increased Tidal and Dynamic Transpulmonary Pressure.
Ventilator dyssynchrony may be associated with increased delivered tidal volumes (V t s) and dynamic transpulmonary pressure (ΔP L,dyn ), surrogate markers of lung stress and strain, despite low V t ventilation. However, it is unknown which types of ventilator dyssynchrony are most likely to increase these metrics or if specific ventilation or sedation strategies can mitigate this potential. ⋯ Double-triggered, flow-limited, early reverse-triggered, and early ventilator-terminated breaths are associated with increases in V t , ΔP L,dyn , and energy. As flow-limited breaths are more than twice as common as double-triggered breaths, further work is needed to determine the interaction of ventilator dyssynchrony frequency to cause clinically meaningful changes in patient outcomes.
