AbstractBackgroundBariatric surgery is by far the most effective treatment option available for successfully achieving and maintaining weight loss in the obese population, but it can also be associated with complications that lead to malnutrition. There is limited data on how enteral nutrition (EN) can be used to provide nutrition support in such cases.MethodsRetrospective review of our Home Enteral Nutrition (HEN) database was conducted from February 2013 to April 2018 to identify patients who received HEN because of bariatric surgery–related complication.ResultsDuring the study period, 72 patients (86% female, mean age 50.3 ± 11.6 years) initiated HEN because of bariatric surgical complication. Most common bariatric surgery was Roux‐en‐Y (74%) and most common indication for HEN was malnutrition/failure to thrive (33%). HEN was most commonly provided through nasojejunal feeds and resulted in an average increase in body weight and body mass index from 74.8 kg and 26.5, respectively, before HEN to 76.9 kg and 27.2, respectively, at the end of the HEN period. Through HEN, patients received 22.2 ± 7.9 kcal/kg/d and 1.0 ± 0.3 g/kg/d protein, meeting 94% ± 17% of their energy goals and 95% ± 29% of their protein goals. Vitamin deficiencies were noted in 69% of patients at the time of HEN initiation, which improved to 10% after enteral feeds and appropriate vitamin supplementation.ConclusionHEN is safe and effective in treating malnutrition and vitamin deficiencies that might occur as a complication of bariatric surgery, leading to avoidance of parenteral nutrition support in most cases.

Albumin has a number of important physiologic functions, which include maintaining oncotic pressure, transporting various agents (fatty acids, bile acids, cholesterol, metal ions, and drugs), scavenging free oxygen radicals, acting as an antioxidant, and exerting an antiplatelet effect. Hypoalbuminemia in adults, defined by an intravascular albumin level of <3.5 g/dL, is associated with poor postoperative outcomes in patients undergoing surgical intervention. Although the relationship of hypoalbuminemia and poor surgical outcome has been known for many years, the pathophysiology behind the relationship is unclear. Three theoretical constructs might explain this relationship. First, albumin might serve as a nutritional marker, such that hypoalbuminemia represents poor nutritional status in patients who go on to experience poor postoperative outcomes. Second, albumin has its own pharmacologic characteristics as an antioxidant or transporter, and therefore, the lack of albumin might result in a deficiency of those functions, resulting in poor postoperative outcomes. Or third, albumin is known to be a negative acute phase protein, and as such hypoalbuminemia might represent an increased inflammatory status of the patient, potentially leading to poor outcomes. A thorough review of the literature reveals the fallacy of these arguments and fails to show a direct cause and effect between low albumin levels per se and adverse outcomes. Interventions designed solely to correct preoperative hypoalbuminemia, in particular intravenous albumin infusion, do little to change the patient's course of hospitalization. While surgeons may use albumin levels on admission for their prognostic value, they should avoid therapeutic strategies whose main endpoint is correction of this abnormality.

Abstract Background Since the introduction of percutaneous endoscopic gastrostomy in the 1980s, the prevalence of home enteral nutrition (HEN) support has increased significantly. Despite these increases, many patients are unable to tolerate standard polymeric formulas (SPFs), resulting in significant healthcare resource utilization. Peptide‐based diets (PBDs) have emerged as a viable option in SPF‐intolerant patients; however, data in the HEN population are lacking. Methods Retrospective review of our prospectively maintained HEN database was conducted to assess tolerance, efficacy, and impact on healthcare utilization in patients on PBDs. Results From January 1, 2016, to May 1, 2018, 95 patients were placed on PBDs, with 53 patients being started directly and 42 patients being transitioned from SPFs. In patients transitioned to PBDs, symptoms of nausea and vomiting, diarrhea, abdominal pain, and distention improved significantly. Healthcare utilization also declined significantly, including mean number of phone calls (1.8 ± 1.6 to 1.1 ± 0.9, P = 0.006), mean number of emergency room visits (0.3 ± 0.6 to 0.09 ± 0.3, P = 0.015), and mean number of provider visits (1.3 ± 1.3 to 0.3 ± 0.5, P < 0.0001). Conclusions Overall, PBDs were well tolerated and resulted in significant improvements in symptoms of gastrointestinal distress and healthcare utilization in patients intolerant to SPFs.

Abstract Background The number of patients requiring home enteral nutrition (HEN) continues to increase. Many of these patients are interested in using blended food instead of, or in addition to, commercial enteral formula (CEF). Increased risk of food‐borne illness is a concern of blenderized tube‐feeding (BTF). This project assessed a standard procedure for minimizing bacterial growth of BTF prepared in the home setting. Methods Fifty participants prepared BTF in their kitchens using a standard preparation procedure to minimize bacterial contamination. BTF was assessed for growth of aerobic microorganisms, Escherichia coli, Staphylococcus aureus , and coliforms at baseline, 24‐hour, and 48‐hour intervals after preparation for a total of 150 colony forming units (CFU) counts performed. Results No sample had zero aerobic microbial counts; yet no substantial increase in microbial counts was observed during the 48 hours. At baseline and 24 hours, 5/50 (10%) had a CFU count of >10 4 , and at 48 hours, 6/50 (12%) exceeded 10 4 CFUs. Out of 150 CFU counts, 2 (1.3%) were just over 10 5 CFU/mL. Samples exceeding 10 4 CFU/mL were likely contaminated by common endospore‐forming bacteria found in soil or by bacteria in milk that was close to its expiration date. Conclusion In this study, 88% of the samples met the US Food Code criteria for safe food consumption; 10.7% met guidelines for marginal safety by other standards; and 1.3% slightly exceeded 10 5 CFUs. Established safe food‐handling procedures can minimize bacterial contamination of BTF and consequently reduce risk of food‐borne infection in HEN patients.

AbstractThe global prevalence of nonalcoholic fatty liver disease (NAFLD) is estimated to be 25% and continues to rise worldwide in the setting of the obesity epidemic. This increase is especially concerning because NAFLD is often a progressive disease that can be associated with significant complications such as liver cirrhosis, hepatocellular carcinoma, and an increase in liver‐related and overall mortality. Because of the devastating complications and comorbidities, NAFLD is a very costly disease for the healthcare system, with estimated annual direct medical costs exceeding $100 billion in the United States alone. Given this progressive course, it is imperative to make the diagnosis in patients with risk factors (metabolic syndrome, weight gain, and insulin resistance/diabetes). Once the diagnosis is made, the focus should shift to treatment and monitoring for the development of associated complications. Given that currently no pharmaceutical intervention is approved for the treatment of NAFLD, focus shifts instead to mitigation of risk factors through avoidance of foods that are rich in red meat, trans fats, refined carbohydrates, and high‐fructose corn syrup; are low fiber; and have high energy density. The landmark of treatment, however, continues to be weight loss and improvement of insulin resistance, often through a multimodality approach. The current manuscript reviews the clinical phenotypes of NAFLD, its risk factors, and pathogenesis, as well as treatment options including lifestyle modifications and dietary interventions, medical therapies, endoscopic bariatric interventions, and bariatric surgery.

AbstractBackgroundPatients with chronic intestinal failure who require long‐term parenteral nutrition rely on central venous catheters (CVCs) for access to nutrition and hydration. With prolonged use, complications such as central line–associated bloodstream infection (CLABSI), damage to CVC, and central venous thrombosis (CVT) can threaten the availability of life‐preserving access. Because of this, all efforts should be made to preserve CVCs with techniques such as catheter salvage in case of CLABSI and catheter repair when damaged. The present study was conducted to evaluate the effectiveness and safety of catheter repair in our patient population.MethodsRetrospective review in 1253 adult patients who received home parenteral nutrition at the Mayo Clinic between September 1, 1997, and April 30, 2018, was conducted to determine the incidence of CLABSI and CVT in patients who underwent CVC repair.ResultsFifty‐five CVC repairs were performed in 36 patients (n = 23 female) with mean age of 57.05 ± 16.96 years. A total of 14 catheters (25.45%) were complicated with 24 episodes of CLABSI. CLABSI rate before and after repair was 0.23/1000 catheter days and 0.21/1000 catheter days, respectively. Most common indications for eventual catheter replacement were mechanical damage (32%), infection (32%), and switching to alternate mode of nutrition (24%). We had a 100% success rate of catheter repair procedure, and no post‐procedural complications were present.ConclusionCatheter repair can increase the catheter survival without increasing the risk of CLABSI, providing not only socioeconomic benefit but also decreasing risk of compromising future vascular access.

Abstract Background : Although home parenteral nutrition (HPN) is lifesaving for patients with chronic intestinal failure (IF), long‐term use can be associated with complications such as infections, metabolic abnormalities, and IF–associated liver disease (IFALD). The key to treatment of many of these complications is prevention. Guidelines recommend avoidance of overfeeding, use of oral/enteral nutrition if possible, cyclic PN, and maintaining dose of soybean oil (SO) intravenous lipid emulsion (ILE) <1 g/kg/day as preventive strategies for IFALD. Additionally, with development of IFALD, ω‐6/ω‐3 polyunsaturated fatty acid ratio should be decreased in ILE. The newly available mixed‐oil (MO) ILE offers such an opportunity; however, there is a paucity of long‐term data available. Methods : The current study reports our long‐term experience with MO ILE use in HPN patients. Results : Seventeen patients (8 female and 9 male) with an average age of 47 ± 12 years and median HPN duration of 4.6 years (1.1–32.1 years) have utilized MO ILE for >12 months after being transitioned from SO ILE because of intolerance. Use of MO ILE allowed an increase in ILE energy from 8% ± 8% to 22% ± 8% while reducing dextrose energy from 66% ± 8% to 54% ± 5%, maintaining stability in alkaline phosphatase and triglyceride levels, and achieving improvement in aspartate aminotransferase, alanine aminotransferase, total bilirubin, and α‐tocopherol levels. Conclusion : In this HPN cohort with SO ILE intolerance, MO ILE was well tolerated and allowed an improvement in macronutrient composition while improving some liver parameters over a 12‐month period.

AbstractPurposeThe increased prevalence of home enteral nutrition (HEN), reemergence of blenderized tube feeding (BTF), and conversion of enteral connectors to the ISO 80369‐3 standard are creating a significant need to better understand the practices of the HEN population. A cross‐sectional survey of current HEN consumers was conducted to evaluate the demographics of HEN consumers, including formulas and feeding tubes being used.MethodsIn order to disseminate the survey to a wide range of HEN consumers, we partnered with private infusion companies (Coram and Pediatric Home Services) along with the Oley and Tube Feeding Awareness Foundations. A validated survey focusing on patient demographics, tube types, formula used, and tube clogging complications was placed online from September 1, 2016, to October 15, 2016.ResultsDuring the study period, 1519 surveys were completed, with 1062 respondents in the pediatric group (<18 years old) and 457 in the adult group (≥18 years old). The most popular formulas were standard polymeric and specialized formulas in both the pediatric and adult groups. However, a significant number in the pediatric (31.2%) and adult (18.6%) groups used BTF either alone or in combination with other formulas. Clogging was also quite prevalent and correlated with tube size.ConclusionsThe present study highlights the significant diversity of the HEN practice in terms of types and sizes of tubes as well as formulas used, including confirmation of the widespread use of BTF. These data are key to ensure HEN providers are able to appropriately support and educate their patients.

AbstractBackgroundMany healthcare facilities and providers prohibit blenderized tube feeding (BTF) for patients who request it due to concerns of high microbial load. The current project compared microbial loads of a standard ready‐to‐feed polymeric commercial formula (CF), a BTF made using baby food (BTF‐BF), and a BTF prepared from blending whole food (BTF‐WF), following food safety standards expected of U.S. hospitals.MethodsThree tube‐feeding formulas (CF, BTF‐BF, BTF‐WF) were prepared in a U.S. hospital and delivered in vitro to an unoccupied patient room. Samples were collected at zero hour, 2 hours, and 4 hours and compared for growth of aerobic microorganisms, Staphylococus aureus, coliforms, and Escherichia coli. The experiment was conducted in triplicate, 1 week apart.ResultsNo S. aureus or coliform/E. coli were detected at any time point following preparation, and total bacterial count was well below acceptable limits. All 3 feeding formulas at zero hour, 2 hours, and 4 hours for each of the 3 sampling dates were acceptable for human consumption.ConclusionJudicious BTF recipe selection and adherence to safe food handling provide a safe feeding substrate equivalent to CF in the hospital setting. Due to increased use and interest in BTF by patients and their caregivers, healthcare facilities may need to reexamine their policies prohibiting BTF use.
