Multicenter StudyThe association between primary language spoken and all-cause mortality in critically ill patients.
The study objective was to investigate the association between primary language spoken and all-cause mortality in critically ill patients. ⋯ In a regional cohort, not speaking English as a primary language is associated with improved outcomes after critical care. Our observations may have clinical relevance and illustrate the intersection of several factors in critical illness outcome including severity of illness, comorbidity, and social and economic factors.

The microcirculation image quality score: Development and preliminary evaluation of a proposed approach to grading quality of image acquisition for bedside videomicroscopy.
Side-stream dark-field microscopy is currently used to directly visualize sublingual microcirculation at the bedside. Our experience has found inherent technical challenges in the image acquisition process. This article presents and assesses a quality assurance method to rate image acquisition quality before analysis. ⋯ Our Microcirculation Image Quality Score addresses many of the common areas where video quality can degrade. The criteria introduced are an objective way to assess the quality of image acquisition, with the goal of selecting videos of adequate quality for analysis. The interrater reliability results in our preliminary study suggest that the Microcirculation Image Quality Score is reasonably repeatable between reviewers. Further assessment is warranted.

Observational StudyElectronic bed weighing vs daily fluid balance changes after cardiac surgery.
The purpose of this study is to establish the validity and reliability of measuring weight in critically ill patients with electronic weighing beds. ⋯ Body weight measured by electronic weighing beds does not seem sufficiently robust or accurate to replace daily FB in ICU. The clinical value of purchasing such beds remains uncertain.

The purpose of this study is to describe the effect of levosimendan (without loading dose) on hemodynamics, inotropes/vasopressors, and mortality in acute heart failure (AHF). ⋯ Levosimendan, without a loading dose, improved cardiac index and perfusion while allowing a reduction in inotropic/vasopressor requirements in patients with AHF.

Elevated asymmetric dimethylarginine levels predict short- and long-term mortality risk in critically ill patients.
Serum concentrations of asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, may contribute to endothelial dysfunction and organ failure in sepsis. We aimed at investigating ADMA levels as a potential diagnostic or prognostic biomarker in critically ill patients. ⋯ Serum ADMA concentrations are significantly elevated in critically ill patients, associated with organ failure and related to short- and long-term mortality risk.
