Nutrition status prior to surgery and nutrition rehabilitation after surgery can affect the morbidity and mortality of pediatric patients. A comprehensive approach to nutrition in pediatric surgical patients is important and includes preoperative assessment, perioperative nutrition considerations, and postoperative recovery. A thorough nutrition assessment to identify patients who are at nutrition risk prior to surgery is important so that the nutrition status can be optimized prior to the procedure to minimize suboptimal outcomes. ⋯ Postoperatively, early feeding has been shown to resolve postoperative ileus earlier, decrease infection rates, promote wound healing, and reduce length of hospital stay. If nutrition cannot be provided orally, then nutrition through either enteral or parenteral means should be initiated within 24-48 hours of surgery. Practitioners should identify those patients who are at the highest nutrition risk for postsurgical complications and provide guidance for optimal nutrition during the perioperative and postoperative period.

Healthcare-associated infections (HAIs) are seen in 17% of critically ill patients. Probiotics, live nonpathogenic microorganisms, may aid in reducing the incidence of infection in critically ill patients. We hypothesized that administration of probiotics would be safe and reduce the incidence of HAIs among mechanically ventilated neurocritical care patients. ⋯ Probiotics are safe to administer in neurocritical care patients; however, this study failed to demonstrate a significant decrease in HAIs or secondary outcomes associated with probiotics.

Initiating enteral nutrition in the postoperative patient can be challenging. Postoperative ileus and bowel edema, bowel anastomosis, and intra-abdominal pathology contribute to the reluctance and inability to achieve adequate nutrition in this patient population. The addition of vasopressors confounds the difficulties. ⋯ Consideration of the vasopressor agent being utilized and its dose is imperative, as are individual patient characteristics. Temporal changes in the dosage should be closely monitored, as increasing doses may reflect worsening clinical status that can be due to intestinal ischemia. Well-designed prospective trials are clearly necessary to address this controversial topic.

Existing trials have not evaluated the feasibility of oral or nasal feeding tube (FT) placement in the critically ill thrombocytopenic oncology population. Thrombocytopenia (TCP) may be considered a contraindication to FT placement due to the potential risk of bleeding complications. ⋯ Critically ill oncology patients with TCP do not appear to be at a higher risk for bleeding complications after FT placement compared with those without TCP, which may be related to blood product transfusion within 24 hours prior to FT placement.

Type 2 diabetes mellitus (T2DM) and obesity represent two of the biggest global health challenges of this century and are associated with significant comorbidities and healthcare costs. Although multiple factors undoubtedly contribute to the development and progression of DM and obesity, research over the last decade has demonstrated that the microbes that colonize the human gut may play key contributory roles. Gut microbes are now known to codevelop with the human host and are strongly influenced by mode of birth and early diet and nutrition, as well as environmental and other factors including antibiotic exposure. ⋯ In addition, it has been shown that the methanogenic Archaea may contribute to altered metabolism and weight gain in the host. However, the majority of studies are performed with stool or colonic samples and may not be representative of the metabolically active small intestine. Studies predominantly in rodent models are beginning to elucidate the mechanisms by which gut microbes contribute to DM and obesity, but much remains to be learned before we can begin to approach targeted treatments.
