Statin therapy as prevention against development of acute respiratory distress syndrome: an observational study.
The 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors ("statins") have anti-inflammatory properties and are associated with improved outcomes in critically ill patients. We investigated whether previous statin therapy affects outcomes in patients at risk for acute respiratory distress syndrome. ⋯ Statin therapy at the time of intensive care unit admission was not associated with a lower rate of development of acute respiratory distress syndrome after matching for patient propensity to receive statins. Statin therapy was not associated with improvements in acute respiratory distress syndrome mortality, organ failure, or days free from mechanical ventilation.

Role of receptor for advanced glycation end products in cardiogenic shock.
Activation of the receptor for advanced glycation end products by its ligands promotes inflammatory processes and tissue injury. The available evidence suggests that soluble forms of receptor for advanced glycation end products circulating in the plasma may neutralize the ligand-mediated damage by acting as a decoy. Thus, it is hypothesized that receptor for advanced glycation end products expression might be deleterious, whereas soluble receptor for advanced glycation end products might be beneficial in cardiogenic shock. However, until now, no data exist regarding the role of soluble receptor for advanced glycation end products and receptor for advanced glycation end products in humans with cardiogenic shock complicating myocardial infarction. ⋯ Enhanced monocytic receptor for advanced glycation end products expression and decreased plasma soluble receptor for advanced glycation end products levels play a central role in patients with cardiogenic shock associated with proinflammatory and destroying pathways, resulting in an enhanced 28-day mortality-rate. Receptor for advanced glycation end products and soluble receptor for advanced glycation end products may be prognostic biomarkers for survival in cardiogenic shock and might represent a novel therapeutic target in cardiogenic shock.

The association between body mass index, processes of care, and outcomes from mechanical ventilation: a prospective cohort study.
To determine the association between excess weight and processes of care and outcomes for critically ill adults. ⋯ Processes of provided care may affect the observed association between excess weight and outcomes for critically ill adults and should be considered when making inferences about observed results. It is unknown if disparities in processes of care are due to clinically justified reasons for variation, bias against heavier patients, or other reasons.

The relationship between organizational culture and family satisfaction in critical care.
Family satisfaction with critical care is influenced by a variety of factors. We investigated the relationship between measures of organizational and safety culture, and family satisfaction in critical care. We further explored differences in this relationship depending on intensive care unit survival status and length of intensive care unit stay of the patient. ⋯ Our findings suggest that the effect of organizational culture on care delivery is most easily detectable by family members of the most seriously ill patients who interact frequently with intensive care unit staff, who are intensive care unit nonsurvivors, and who spend a longer time in the intensive care unit. Positive relationships between measures of organizational and safety culture and family satisfaction suggest that by improving organizational culture, we may also improve family satisfaction.
