Randomized Controlled Trial Multicenter StudyHigh-Flow Nasal Cannula Oxygenation in Immunocompromised Patients With Acute Hypoxemic Respiratory Failure: A Groupe de Recherche Respiratoire en Réanimation Onco-Hématologique Study.
In immunocompromised patients with acute respiratory failure, invasive mechanical ventilation remains associated with high mortality. Choosing the adequate oxygenation strategy is of the utmost importance in that setting. High-flow nasal oxygen has recently shown survival benefits in unselected patients with acute respiratory failure. The objective was to assess outcomes of immunocompromised patients with hypoxemic acute respiratory failure treated with high-flow nasal oxygen. ⋯ In immunocompromised patients with hypoxemic acute respiratory failure, high-flow nasal oxygen when compared with standard oxygen did not reduce intubation or survival rates. However, these results could be due to low statistical power or unknown confounders associated with the subgroup analysis. A randomized trial is needed.

Randomized Controlled Trial Multicenter StudyRelationship Between Alternative Resuscitation Strategies, Host Response and Injury Biomarkers, and Outcome in Septic Shock: Analysis of the Protocol-Based Care for Early Septic Shock Study.
The Protocol-based Care for Early Septic Shock trial found no differences across alternative resuscitation strategies in all-cause mortality. A separate aim was to determine whether differences in resuscitation strategies affected trajectories of biomarkers of key pathways associated with downstream clinical outcomes of sepsis and whether there were differences in survival across treatment arms for patients with different baseline biomarker profiles. ⋯ In patients with septic shock, alterations in inflammation, coagulation, oxidative stress, and tissue hypoxia are common and associated with adverse outcomes but are not influenced by protocol-based resuscitation compared with usual care. However, contrary to expectation, protocol-based resuscitation appeared to be superior in patients with lower concentrations of inflammatory biomarkers. The mechanisms responsible for this effect are unclear.

Multicenter StudyMuscle Weakness and 5-Year Survival in Acute Respiratory Distress Syndrome Survivors.
To longitudinally evaluate the association of post-ICU muscle weakness and associated trajectories of weakness over time with 5-year survival. ⋯ At hospital discharge, greater than one third of acute respiratory distress syndrome survivors had muscle weakness. Greater strength at discharge and throughout follow-up was associated with improved 5-year survival. In patients with post-ICU weakness, both persisting and resolving trajectories were commonly experienced and associated with worse survival during follow-up.

Multicenter Study Observational StudyPrior Use of Calcium Channel Blockers Is Associated With Decreased Mortality in Critically Ill Patients With Sepsis; a Prospective Observational Study.
Experimental studies suggest that calcium channel blockers can improve sepsis outcome. The aim of this study was to determine the association between prior use of calcium channel blockers and the outcome of patients admitted to the ICU with sepsis. ⋯ Prior calcium channel blocker use is associated with reduced mortality in patients following ICU admission with sepsis.

Multicenter Study Comparative StudyPerceived Nonbeneficial Treatment of Patients, Burnout, and Intention to Leave the Job Among ICU Nurses and Junior and Senior Physicians.
Perceiving nonbeneficial treatment is stressful for ICU staff and may be associated with burnout. We aimed to investigate predictors and consequences of perceived nonbeneficial treatment and to compare nurses and junior and senior physicians. ⋯ Perceiving nonbeneficial treatment is related to burnout and may increase intention to leave. Efforts to reduce perception of nonbeneficial treatment should improve the work environment and should be tailored to the different experiences of nurses and junior and senior physicians.
