ReviewVitamin C supplementation in the critically ill patient.
Vitamin C is not only an essential nutrient involved in many anabolic pathways, but also an important player of the endogenous antioxidant defense. Low plasma levels are very common in critical care patients and may reflect severe deficiency states. ⋯ The recent research on the modulation of oxidative stress and endothelial protection offer interesting therapeutic perspectives, based on the biochemical evidence, with limited or even absent side-effects.

ReviewShould enteral nutrition be started in the first week of critical illness?
To review the mechanistic evidence for early enteral nutrition in critically ill patients within the first week of ICU admission. ⋯ Despite the wide range of quality in the current clinical outcomes evidence, early enteral nutrition within the first week of ICU admission, delivered to the appropriate patient, promotes gut-mediated immunity, lowers metabolic response to stress, maintains microbial diversity, and improves clinical outcomes versus standard of care or parenteral nutrition therapy.
