Impact of Family Presence on Delirium in Critically Ill Patients: A Retrospective Cohort Study.
To assess the effect of family presence on the prevalence and duration of delirium in adults admitted to an ICU. ⋯ The effects of family presence on delirium are complex and dependent on type of visitation, reason for ICU admission, and brain function on ICU admission.

Observational StudyChanges in vitamin D metabolites at the time of critical illness and 6 months later-A prospective observational study.
Despite multiple studies suggesting that low 25(OH)D-vitamin levels are associated with worse outcomes in critically ill individuals, attempts to mitigate the outcomes by fixed dose enteral supplementation unguided by baseline or target blood levels have been unsuccessful. Since a single measurement of 25(OH)D may not optimally reflect an individual's vitamin D status, we studied the plasma concentration of different vitamin D metabolites and their recovery during and following resolution of acute critical illness. ⋯ In critically ill patients, levels of multiple vitamin D metabolites are low but substantial recovery occurs following resolution of acute illness. It is unclear whether a single metabolite is sufficient to assess vitamin D status of critically ill patients and guide potential supplementation.

Background: Uneven body-surface thermal distribution is a manifestation of hypoperfusion and can be quantified by infrared thermography. Our aim was to investigate whether body-surface thermal inhomogeneity could accurately evaluate the severity of patients at risk of hypoperfusion. Methods: This was a prospective cohort study in which infrared thermography images were taken from unilateral legs of critically ill patients at high risk of hypoperfusion in a cardiac surgical intensive care unit. ⋯ These thermal parameters are associated with CRT, lactate, and blood pressure. The AUROC of a combined prediction incorporating three thermal inhomogeneity parameters (SD, kurtosis, and entropy) was considerably higher at 0.866. Conclusions: Body-surface thermal inhomogeneity provided a noninvasive and accurate assessment of the severity of critically ill patients at high risk of hypoperfusion.
