Meta Analysis
Vitamin D supplementation in the critically ill: A systematic review and meta-analysis.
Vitamin D insufficiency is reported in up to 50% of the critically ill patients and is associated with increased mortality, length of stay (LOS) in intensive care unit (ICU) and hospital, and respiratory disorders with prolonged ventilation. Benefits of vitamin D supplementation remain unclear. The aim of this systematic review was to evaluate the clinical benefits of vitamin D administration in critically ill patients. ⋯ In critically ill patients, Vitamin D administration does not improve clinical outcomes. The statistical imprecision could be explained by the sparse number of trials.

Children with congenital heart disease (CHD) are often growth restricted (low weight- and/or height-for-age) which may increase risk of poor post operative resilience. Bioelectrical impedance spectroscopy (BIS) has been used to determine body composition in different clinical settings and has been shown to mark differences in nutritional state and clinical outcome. In disease conditions were fluid is not normally distributed it is proposed that raw impedance values and BIS derived phase-angle may serve as prognostic indicators of clinical outcome. We sought to describe the relationship between nutritional status, phase-angle and post-operative outcomes in children with congenital heart disease. ⋯ Moderate malnutrition (HAZ ≤-2) in infants and children undergoing cardiac surgery is associated with longer PICU-LOS. Post-operative measures of BIS phase angle may further improve our ability to identifying hose children with an increased risk of prolonged PICU-LOS compared to using pre-operative anthropometry alone.
