Abstract
BACKGROUND Perioperative enteral nutrition (EN) enriched with immune-modulating substrates is preferable for patients undergoing major abdominal cancer surgery. In this study, perioperative EN enriched with immune-modulating nutrients such as arginine, glutamine, and omega-3 fatty acids was evaluated for its anti-inflammatory efficacy in patients with gastric adenocarcinoma or gastrointestinal stromal tumor (GIST) receiving curative surgery. MATERIALS AND METHODS This prospective, randomized, double-blind study recruited 34 patients with gastric adenocarcinoma or gastric GIST undergoing elective curative surgery. These patients were randomly assigned to the study group, receiving immune-modulating nutrient-enriched EN, or the control group, receiving standard EN from 3 days before surgery (preoperative day 3) to up to postoperative day 14 or discharge. Laboratory and inflammatory parameters were assessed on preoperative day 3 and postoperative day 14 or at discharge. Adverse events (AEs) and clinical outcomes were documented daily and compared between groups. RESULTS No significant differences were observed between the two groups in selected laboratory and inflammatory parameters, or in their net change, before and after treatment. AEs and clinical outcomes, including infectious complications, overall complications, time to first bowel action, and length of hospital stay after surgery, were comparable between treatment groups (all P > 0.05). CONCLUSION Immune-modulating nutrient-enriched EN had no prominent immunomodulation effect compared with that of standard EN.

[Innovation in the incorporation of macronutrients to enteral nutrition formulas].
Gil Hernández, Á
Nutricion hospitalaria. 2018;(Spec no2):4-12
Abstract
Enteral nutrition consists of the administration of chemically defined nutrients which are partially or fully metabolised in the intestinal tract, by the oral route or through a tube, to get an adequate and efficient nutritional supply. Enteral nutrition is the first option when one needs artificial nutrition, keeping parenteral nutrition only for those cases for which enteral nutrition would be insufficient or impossible. Enteral nutrition formulas are classified according to their composition with complete or uncompleted supply of nutrients, administration route, and protein content, energy density and type and content of fibre, and in second term according to general or special purposes utilization. Indeed, enteral nutrition formulas can be grouped as polymeric, oligomeric, organ-specific, therapeutic formulas, and nutrition supplements and modules. All these formulas are susceptible of improvement and innovation based mainly on the knowledge of diseases physiopathology, composition and functionality of food ingredients, which in turn contain a number of specific nutrients and bioactive compounds able to exert particular effects on the patient, and on technological treatment technology that will result in the amelioration of nutrient bioavailability. The present work reviews some of the most relevant functional ingredients used today in the innovation of enteral formulas, as well as their main physiological and biochemical effects in selected pathologies.

Nutricion hospitalaria. 2018;(6):1257-1262
Abstract
BACKGROUND the effective contribution of enteral nutrition (EN) in intensive care units (ICU) is due to multiple factors. OBJECTIVES to determine the efficacy of caloric intake in critically ill patients with traumatic pathology receiving enteral nutrition, and to analyze cause and time of interruption of EN. METHOD prospective observational study (November 2015 - August 2016). INCLUSION CRITERIA patient with EN ≥ 48 hours and age ≥ 18 years. EXCLUSION CRITERIA patient with oral and/or parenteral nutrition. VARIABLES demographic, day of EN, prescribed and administered kilocalories (kcal), caloric difference, caloric objective and variables related to the interruptions of the EN. The handling of EN and interruptions are made according to the unit's internal protocol. Kcal/patient are calculated according to the Harris-Benedict equation and multiplied by a stress factor depending on the type of trauma of the patient. RESULTS sixty-nine patients were included, 79.71% were men, with a median age of 46 (34-58) years. A total of 1,112 days of EN were monitored. As of the third day of admission to the ICU (979 days monitored), the nutritional efficacy was optimal (caloric intake > 80%): 92.43% (72.8-97.5). The optimal caloric goal was maintained in 67.9% of these days. The most frequent causes of interruption of NE were procedures unrelated to airway, with holding time of three (1-7.25) hours. CONCLUSIONS at the third day, the patients with traumatic pathology received at least 80% of the prescribed caloric intake. Among the most frequent causes of interruption of EN were the procedures unrelated to airway.

Abstract
BACKGROUND Early enteral nutrition (EEN) after surgery had been reported to decrease morbidity and mortality. However, no meta-analysis performed on nutrition status and recovery after surgery to Colorectal cancer (CRC). AIM: We aimed to estimate effect of EEN for postoperative CRC. METHODS Electronic databases were searched for randomized controlled trials published prior to September 2017. Papers comparing EEN after surgery to traditional nutritional regimen in CRC patients were selected. The chosen articles should containe one or more of the following outcome measures: serum albumin, prealbumin, transferrin, time to first flatus and postoperative hospital stay. RESULTS 2307 cases from 26 studies were included. The analysis showed that EEN was more effective in increasing serum albumin and prealbumin, promoting the recovery of gastrointestinal function, and decreasing the time of postoperative hospital stay, especially for colon cancer. CONCLUSION EEN can improve nutritional status and promote intestinal function recovery for patients undergoing CRC surgery.

Abstract
OBJECTIVE Head and neck cancer patients experience unintentional weight loss and malnutrition at diagnosis, during oncologic treatment, and after the end of therapy because of reduction of eating ability. The aim of the present study was to assess nutrition intervention efficacy in maintaining basal nutritional conditions. METHODS Head and neck cancer patient candidates for chemoradiotherapy and requiring enteral nutrition (EN) support through gastrostomy, according to international guidelines, were included in the study. Nutritional intervention aimed to reach 30 kcal/kg/d, considering both EN and oral intake. Adjustments were made during and after treatment, aiming to maintain stable or improving nutritional indicators. Anthropometry, body composition measured by bioelectrical impedance vector analysis, and oral and EN intake were monitored at baseline (before chemoradiotherapy) and at 1, 3, and 6 mo. RESULTS A total of 54 patients were evaluated; 35 patients completed follow-up at 6 mo and were included in the analysis. At baseline, mean weight loss in the last 6 mo was 12 ± 7.9%; mean body mass index and phase angle were 20.6 ± 3.9 kg/m2 and 4.8 ± 1.2°. Before chemoradiotherapy 21 patients (60%) were able to eat; the percentage decreased during and after treatment to 34.3% (P = 0.026) at 1 and 3 mo and at 51.4% at 6 mo. From the analysis, a mean daily energy intake of 35 ± 10 kcal/kg was needed to maintain stable body weight and phase angle during and after treatment. CONCLUSION To preserve body weight and composition, we identified an energy requirement greater than expected both during and after chemoradiotherapy.

Journal of clinical anesthesia. 2018;:62-92
Abstract
STUDY OBJECTIVE To analyze the effect of enteral nutrition compared with parenteral nutrition in critically ill patients. DESIGN Systematic review and meta-analysis of randomized controlled trials. SETTING Intensive care unit. PATIENTS 23 trials containing 6478 patients met our inclusion criteria. INTERVENTION A systematical literature search was conducted to identify eligible trials in electronic databases including PubMed, Embase, Scopus, EBSCO and Cochrane Library. The primary outcome was mortality, the secondary outcomes were gastrointestinal complications, bloodstream infections, organ failures, length of stay in ICU and hospital. We performed a predefined subgroup analyses to explore the treatment effect by mean age, publication date and disease types. MAIN RESULTS The result showed no significant effect on overall mortality rate (OR 0.98, 95%CI 0.81 to 1.18, P = 0.83, I2 = 19%) and organ failure rate (OR 0.87, 95%CI 0.75 to 1.01, P = 0.06, I2 = 16%). The use of EN had more beneficial effects with fewer bloodstream infections when compared to PN (OR 0.59, 95%CI 0.43 to 0.82, P = 0.001, I2 = 27%) and this was more noteworthy in the subgroup analysis for critical surgical patients (OR 0.36, 95%CI 0.22 to 0.59, P < 0.0001, I2 = 0%). EN was associated with reduction in hospital LOS (MD -0.90, 95%CI -1.63 to -0.17, P = 0.21, I2 = 0%) but had an increase incidence of gastrointestinal complications (OR 2.00, 95%CI 1.76 to 2.27, P < 0.00001, I2 = 0%). CONCLUSION For critically ill patients, the two routes of nutrition support had no different effect on mortality rate. The use of EN could decrease the incidence of bloodstream infections and reduce hospital LOS but was associated with increased risk of gastrointestinal complications.

BMC gastroenterology. 2018;(1):11
Abstract
BACKGROUND Nutrition support is a common means for patients with gastric cancer, especially for those undergoing elective surgery. Recently, enteral immunonutrition (EIN) was increasingly found to be more effective than enteral nutrition (EN) in enhancing the host immunity and eventually improving the prognosis of gastric cancer patients undergoing gastrectomy. However, the results reported were not consistent. This meta-analysis aimed to assess the impact of EIN for patients with GC on biochemical, immune indices and clinical outcomes. METHODS Four electronical databases (Medline, EMBASE, Scopus and Cochrane library) were used to search articles in peer-reviewed, English-language journals. Mean difference (MD), Relative risk (RR), or standard mean difference (SMD) with 95% confidence interval (CI) were calculated. Heterogeneity was assessed by Cochrane Q and I2 statistic combined with corresponding P-value. The analysis was carried out with RevMan 5.3. RESULTS Seven studies involving 583 patients were eligible for the pooled analysis. EIN, when beyond a 7-day time-frame post-operatively (D ≥ 7), increased level of CD4+ (SMD = 0.99; 95% CI, 0.65-1.33; P < 0.00001), CD4+/ CD8+ (SMD = 0.34; 95% CI, 0.02-0.67; P = 0.04), the IgM (SMD = 1.15; 95% CI, 0.11-2.20; P = 0.03), the IgG (SMD = 0.98; 95% CI, 0.55-1.42; P < 0.0001), the lymphocyte (SMD = 0.69; 95% CI, 0.32-1.06; P = 0.0003), and the proalbumin (SMD = 0.73; 95% CI, 0.33-1.14; P = 0.0004). However, those increased effects were not obvious within a 7-day time-frame post-operatively (D < 7). The levels of CD8+ and other serum proteins except proalbumin were not improved both on D ≥ 7 and D < 7. Clinical outcomes such as systemic inflammatory response syndrone (SIRS) (MD, - 0.89 days; 95% CI, - 1.40 to - 0.39; P = 0.005), and postoperative complications (RR, 0.29; 95% CI, 0.14-0.60; P = 0.001) were significantly reduced in EIN group. Pulmonary infection and length of hospitalization (LHS) were not improved no matter what time after surgery. CONCLUSIONS EIN was found to improve the cellular immunity, modulate inflammatory reaction and reduce postoperative complication for GC patients undergoing radical gastrointestinal surgery. Exclusion of grey literature and non-English language studies was the key limitation in this study.

Abstract
PURPOSE To investigate the role of percutaneous transhepatic cholangial drainage (PTCD) combined with percutaneous endoscopic jejunostomy (PEJ) in maintaining the nutrition state in patients with advanced ampullary neoplasms. MATERIALS AND METHODS Sixty patients who suffered from advanced ampullary neoplasms and could not tolerate internal drainage operation or biliary stent placement were enrolled. After PTCD, PEJ was implemented, and then the enteral nutrient solution + bile were instilled through PEJ tube for enteral nutrition support. Before and 1, 2, 3, and 4 weeks after surgery, the body weight, bilirubin, liver function, nutritional status, and immunologic function indexes were detected and compared. RESULTS All patients had successfully completed PTCD combined with PEJ, and no serious complication occurred. The body mass index of the patients from 4 weeks after surgery was significantly higher than before (P < 0.05). From 2 weeks, both serum total bilirubin and direct bilirubin levels were significantly lower than before (P < 0.05). From 1 week, both alanine aminotransferase and aspartate aminotransferase levels were significantly lower than before (P < 0.05); from 2 weeks, the level of gamma-glutamyl transferase was significantly lower than before (P < 0.05). From 1 week, the levels of albumin, transferrin, and prealbumin were significantly increased compared with before (P < 0.05), and serum CD3+ cell content, CD4+ cell content, and CD4+/CD8+ ratio were significantly improved compared with before (P < 0.05). CONCLUSION PTCD combined with PEJ is a safe and effective method for maintaining nutrition state in patients with advanced ampullary neoplasms.

Abstract
OBJECTIVES Pancreatic insufficiency (PI) and malabsorption of fats lead to reduced caloric intake, inability to maintain weight, and increased gastrointestinal symptoms. Thus, enteral nutrition (EN) is used in patients with cystic fibrosis (CF) and poor nutritional status. The current study evaluated safety, tolerability, and improvement of fatty acid (FA) status in red blood cell (RBC) membranes, a marker of long-term FA absorption, with an in-line digestive cartridge (RELiZORB) that hydrolyzes fat in enteral formula. METHODS Patients with CF receiving EN participated in a multicenter, 90-day open-label study during which RELiZORB was used with overnight EN. The primary endpoint was change over time in RBC uptake of docosahexaenoic acid (DHA)+ eicosapentaenoic acid (EPA). Gastrointestinal symptoms were collected to evaluate safety and tolerability. Several clinical and anthropometric parameters were also assessed throughout the study. RESULTS A total of 36 subjects completed the study with a mean age of 13.8 years, body mass index of 17.7 and 6.2 years mean use of overnight EN. Fat absorption significantly improved as shown by increased RBC levels of DHA+EPA, improved ω-6/ω-3 ratio, and increased plasma levels of DHA+EPA. RELiZORB use was not associated with any unanticipated adverse events. CONCLUSIONS RELiZORB use was found to be safe, well tolerated, and resulted in increased levels of FAs in RBCs and plasma. This is the first prospective study to show EN can improve FA abnormalities in CF. Because improvement in omega-3 levels has been shown to help pulmonary and inflammatory status as well as anthropometric parameters in CF, RELiZORB may have important long-term therapeutic benefits in patients with CF.

Knowledge of Constituent Ingredients in Enteral Nutrition Formulas Can Make a Difference in Patient Response to Enteral Feeding.
Savino, P
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2018;(1):90-98
Abstract
Enteral feeding is considered the preferred method for providing a complete or supplemental source of nutrition to patients. Enteral formulas (EFs) are traditionally assessed from general information provided by the manufacturer such as caloric density, percentage of macronutrients, and micronutrients to meet the Recommended Dietary Allowance. Sometimes labeling information highlights particular ingredients to indicate specific properties at a metabolic or nutrition level. However, it is necessary to review the quality and composition of any enteral formula, since the basic components are responsible for tolerance and nutrition efficacy, and this should not be overshadowed by the benefit of a single constituent. Intolerance to EF is commonly attributed to individual patient response or to the means of administration. The objective of this review is to highlight the importance of appraising EFs with regard to composition and effect on the gastrointestinal tract.
