Review Meta AnalysisPredicting Neurologic Outcome After Targeted Temperature Management for Cardiac Arrest: Systematic Review and Meta-Analysis.
Targeted temperature management improves survival and neurologic outcomes for adult out-of-hospital cardiac arrest survivors but may alter the accuracy of tests for predicting neurologic outcome after cardiac arrest. ⋯ Simple bedside tests and somatosensory-evoked potentials predict poor neurologic outcome for survivors of cardiac arrest treated with targeted temperature management, and specificity improves when performed beyond 72 hours. Clinicians should use caution with these predictors as they carry the inherent risk of becoming self-fulfilling.

Randomized Controlled Trial Multicenter Study Comparative Study Observational StudyTiming of Renal Replacement Therapy and Patient Outcomes in the Randomized Evaluation of Normal Versus Augmented Level of Replacement Therapy Study.
To explore the relationship between timing of continuous renal replacement therapy commencement and clinical outcomes in critically ill patients with acute kidney injury. The primary outcomes were all-cause mortality at 28 and 90 days. ⋯ In a subgroup of participants of the Randomized Evaluation of Normal Versus Augmented Level Replacement Therapy Study, earlier commencement of continuous renal replacement therapy relative to RIFLE-I acute kidney injury was not significantly associated with improved survival. Additional studies with larger sample sizes and broader commencement times are warranted.

Multicenter Study Observational StudyInitial Lactate and Lactate Change in Post-Cardiac Arrest: A Multicenter Validation Study.
Rate of lactate change is associated with in-hospital mortality in post-cardiac arrest patients. This association has not been validated in a prospective multicenter study. The objective of the current study was to determine the association between percent lactate change and outcomes in post-cardiac arrest patients. ⋯ Lower lactate levels at 0, 12, and 24 hours and greater percent decrease in lactate over the first 12 hours post cardiac arrest are associated with survival and good neurologic outcome.

Multicenter StudyStatins and Delirium During Critical Illness: A Multicenter, Prospective Cohort Study.
Since statins have pleiotropic effects on inflammation and coagulation that may interrupt delirium pathogenesis, we tested the hypotheses that statin exposure is associated with reduced delirium during critical illness, whereas discontinuation of statin therapy is associated with increased delirium. ⋯ In critically ill patients, ICU statin use was associated with reduced delirium, especially early during sepsis; discontinuation of a previously used statin was associated with increased delirium.

Multicenter StudySerious Adverse Events Associated With Vasopressin and Norepinephrine Infusion in Septic Shock.
The frequency, risk factors, and mortality rates of serious adverse events associated with the use of vasopressin and norepinephrine are not clear. The objectives of this study were to determine frequency, risk factors (including candidate gene polymorphisms), and outcomes of serious adverse events in septic shock patients. ⋯ Serious adverse events associated with vasopressin and norepinephrine in patients who have septic shock are associated with increased mortality and morbidity. AA genotype of rs28418396 single-nucleotide polymorphism near the arginine vasopressin receptor 1b gene is associated with serious adverse events. The mechanism of this association requires investigation.
