To highlight the recent developments in nutritional support for critically ill patients. ⋯ Together, current findings indicate that intragastric enteral nutrition should be initiated within 24 h of admission to ICU and supplementary parenteral nutrition should be avoided. Future research should aim to clarify the optimal energy delivery for best clinical outcomes, and the role of small intestinal function and its flora in nutritional care and clinical outcomes.

Anemia and iron deficiency are the most common extraintestinal complications of inflammatory bowel diseases (IBDs) and are often undertreated. We review the evidence on intravenous (i.v.) iron overcoming the limitations of oral iron in IBD. ⋯ Oral iron is not an ideal option for treating anemia and iron deficiency in IBD. i.v. iron should be preferred at least in five scenarios: intolerance to oral iron, severe anemia, failure of oral therapy, need for a quick recovery, and use of erythropoietin. Direct evidence in IBD patients not only confirms the effectiveness of i.v. iron, but also demonstrates that new, more convenient preparations probably will become the standard in the near future.
