Adipose tissue alterations in critical illness: a paradox as to patient outcomes

Adipocyte morphological changes in critically ill patients have been reported, potentially providing beneficial effects. Marques and colleagues reported that these morphological adipocyte changes, as well as accumulation of M2 phenotype macrophages, occur irrespective of nutritional status in the critically ill. The present study provides insight into the alterations that occur, although further studies are needed to fully understand the role that adipose tissue plays in the critically injured.
