Randomized Controlled Trial Comparative Study
Rhubarb to Facilitate Placement of Nasojejunal Feeding Tubes in Patients in the Intensive Care Unit.
Prokinetic agents are sometimes needed to aid in the placement of nasojejunal feeding tubes in patients at risk of malnutrition. The objective of the present study was to evaluate the feasibility of rhubarb as a new prokinetic agent to replace metoclopramide and erythromycin in the placement of nasojejunal feeding tubes. ⋯ Rhubarb could serve as an effective prokinetic agent to promote the insertion of nasojejunal feeding tubes.

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.

Enteral nutrition (EN) is the preferred route of nutrient delivery in critically ill patients. Research has consistently described an incomplete delivery of EN in critically ill patients. The purpose of this study was to investigate barriers to reach and maintain >90% prescribed EN among critically ill medical intensive care unit (ICU) patients. ⋯ Suboptimal EN volume delivery continues to be an issue in critically ill patients. Our study identified initiation and advancement of EN as the most common reason for suboptimal EN volume delivery. Variation in practice was noted within several categories, and multiple reversible barriers to optimal EN delivery were identified. These data can serve as the impetus to modify practice models and workflow to optimize EN delivery among critically ill patients.

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.
