Statistical analysis plan for the replacing protein via enteral nutrition in a stepwise approach in critically ill patients (REPLENISH) randomized clinical trial.

BACKGROUND: The optimal amount and timing of protein intake in critically ill patients are unknown. REPLENISH (Replacing Protein via Enteral Nutrition in a Stepwise Approach in Critically Ill Patients) trial evaluates whether supplemental enteral protein added to standard enteral nutrition to achieve a high amount of enteral protein given from ICU day five until ICU discharge or ICU day 90 as compared to no supplemental enteral protein to achieve a moderate amount of enteral protein would reduce all-cause 90-day mortality in adult critically ill mechanically ventilated patients. METHODS: In this multicenter randomized trial, critically ill patients will be randomized to receive supplemental enteral protein (1.2 g/kg/day) added to standard enteral nutrition to achieve a high amount of enteral protein (range of 2-2.4 g/kg/day) or no supplemental enteral protein to achieve a moderate amount of enteral protein (0.8-1.2 g/kg/day). The primary outcome is 90-day all-cause mortality; other outcomes include functional and health-related quality-of-life assessments at 90 days. The study sample size of 2502 patients will have 80% power to detect a 5% absolute risk reduction in 90-day mortality from 30 to 25%. Consistent with international guidelines, this statistical analysis plan specifies the methods for evaluating primary and secondary outcomes and subgroups. Applying this statistical analysis plan to the REPLENISH trial will facilitate unbiased analyses of clinical data. CONCLUSION: Ethics approval was obtained from the institutional review board, Ministry of National Guard Health Affairs, Riyadh, Saudi Arabia (RC19/414/R). Approvals were also obtained from the institutional review boards of each participating institution. Our findings will be disseminated in an international peer-reviewed journal and presented at relevant conferences and meetings. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04475666 .

Effects of olfactory and/or gustatory stimuli on feeding of preterm infants: A systematic review and meta-analysis.

AIM: To evaluate the effect of olfactory and/or gustatory stimulation interventions on feeding outcomes in preterm infants. METHODS: We conducted systematic searches across various academic databases, including PubMed, Embase, Web of Science, the Cochrane Library, the Chinese Biomedical Literature Service System, China National Knowledge Infrastructure, the Wanfang Database, and the Wipu Database. These searches aimed to identify randomized controlled trials investigating the impact of olfactory and/or gustatory stimulation on preterm infants. The search period spanned from the inception of the databases until December 2022. Two independent evaluators autonomously reviewed the literature, extracted pertinent data, assessed the quality of the included studies, and conducted a meta-analysis using RevMan 5.3 software. RESULTS: A total of 7 randomized controlled trials or quasi-experimental studies were included, with a total of 871 participants. Olfactory and gustatory stimulation demonstrated a reduction in the time to full enteral feeds in preterm infants when compared to usual care (MD = -1.60 days; 95% CI = -2.31, -0.89; p<0.0001). No substantial evidence was identified regarding the influence of olfactory and gustatory stimulation on the duration of gastric tube placement, length of hospitalization, incidence of necrotizing enterocolitis, or occurrence of spontaneous bowel perforation in preterm infants. CONCLUSIONS: Olfactory and gustatory stimulation show potential benefits for preterm infants. However, due to the low to very low level of certainty associated with the available data, our ability to assess the effects is limited. Further trials and studies are essential to enhance our understanding of the mechanisms and effectiveness of olfactory and gustatory stimulation therapies.

Strategies to Promote Success in Oral Feedings in Infants and Children with Intestinal Failure due to Short Bowel Syndrome.

Infants and children with intestinal failure are at risk for pediatric feeding disorders, which challenge their oral feeding development. This article explores these challenges and offers several practical strategies that can be used by multidisciplinary care teams and at-home caregivers to help support the development of oral feeding in these children and eventually lead to their attaining enteral autonomy.

The association between enteral nutrition with survival of critical patients with COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) results in several complications and mortality in intensive care unit (ICU) patients. Limited studies have investigated the effect of enteral nutrition (EN) on the survival of COVID-19 patients in the ICU. The aim of this study was to investigate the association of EN with biochemical and pathological indices associated with mortality in ICU patients with COVID-19. METHODS: This case-control study was conducted on 240 patients with COVID-19 hospitalized in the ICU including 120 eventual nonsurvived as the cases and 120 survived patients as the controls. All of the patients received EN as a high protein high volume or standard formula. Data on general information, anthropometric measurements, and the results of lab tests were collected. RESULTS: The recovered patients received significantly more high protein (60.8% vs. 39.6%, p = .004) and high volume (61.6% vs. 42.3%, p = .005) formula compared to the nonsurvived group. Mortality was inversely associated with high volume (odds ratio [OR]: 0.45 confidence interval [CI]95%, p = .008) and high protein (OR: 0.42 CI95%, p = .003) formula. The results remained significant after adjusting for age and sex. Further adjustment for underlying diseases, smoking, body mass index, and the acute physiology and chronic health evaluation II (APACHE II) score did not change the results. CONCLUSION: The findings of the study showed that there was a significant inverse association between mortality and high volume and high protein formula in patients with COVID-19. Further investigation is warranted.

Trophic Nutrition in ICU Patients Undergoing High-Flow Oxygen Therapy and/or Noninvasive Mechanical Ventilation: The Nutri-Trophic Study.

Enteral nutrition (EN) therapy in ICU patients requiring oxygen therapy with high-flow nasal cannula (HFNC) and/or noninvasive mechanical ventilation (NIMV) is controversial. A prospective, cohort, observational, and multicenter study was conducted in 10 ICUs in Spain to analyze the 90-day mortality, tolerance, side effects, and infectious complications of trophic EN in patients requiring HFNC therapy and/or NIVM. A total of 149 patients were enrolled. The mean age, severity scores, tracheobronchitis, bacteremia, and antimicrobial therapy were significantly higher in deceased than in living patients (p < 0.05), and the mortality rate was 14.8%. A total of 110 patients received oral trophic feedings, 36 patients received nasogastric tube feedings (NGFs), and 3 received mixed feedings. Trophic EN was discontinued in only ten (14.9%) patients because of feeding-related complications. The variables selected for the multivariate logistic regression on feeding discontinuation were SOFA upon admission (OR per unit = 1.461) and urea (OR per mg/dL = 1.029). There were no significant differences in the development of new infections according to the route of EN administration. Early trophic feeding administered to patients with acute respiratory failure requiring noninvasive ventilation is safe and feasible, and is associated with few dietary and infectious complications in a mortality, setting comparable to similar studies.

Evaluation of a Novel Enteral Phosphorus Therapy with Enteral Nutrition during a National Intravenous Sodium Phosphate Shortage.

The purpose of this study was to evaluate the efficacy and safety of intragastric administration of small volumes of sodium enema solution containing phosphorus as phosphorus replacement therapy in critically ill patients with traumatic injuries who required continuous enteral nutrition. Adult patients (>17 years of age) who had a serum phosphorus concentration <3 mg/dL (0.97 mmol/L) were evaluated. Patients with a serum creatinine concentration >1.4 mg/dL (124 µmol/L) were excluded. Patients were given 20 mL of saline enema solution intragastrically, containing 34 mmol of phosphorus and mixed in 240 mL water. A total of 55% and 73% of patients who received one (n = 22) or two doses (n = 11) had an improvement in the serum phosphorus concentration, respectively. The serum phosphorus concentration increased from 2.5 [2.1, 2.8] mg/dL (0.81 [0.69, 0.90] mmol/L) to 2.9 [2.2, 3.0] mg/dL (0.94 [0.71, 0.97 mmol/L) for those who received two doses (p = 0.222). Excluding two patients with a marked decline in serum phosphorus by 1.3 mg/dL (0.32 mmol/L) resulted in an increase in the serum phosphorus concentration from 2.3 [2.0, 2.8] mg/dL (0.74 [0.65, 0.90] mmol/L) to 2.9 [2.5, 3.2] mg/dL (0.94 [0.81, 1.03] mmol/L; n = 9; p = 0.012). No significant adverse effects were noted. Our data indicated that intragastric phosphate administration using a small volume of saline enema solution improved the serum phosphorus concentrations in most patients.

Exposure to the smell and taste of milk to accelerate feeding in preterm infants.

BACKGROUND: Preterm infants (born before 37 weeks' gestation) are often unable to co-ordinate sucking, swallowing, and breathing for oral feeding because of their immaturity. In such cases, initial nutrition is provided by orogastric or nasogastric tube feeding. Feeding intolerance is common and can delay attainment of full enteral and sucking feeds, prolonging the need for nutritional support and the hospital stay. Smell and taste play an important role in the activation of physiological pre-absorptive processes that contribute to food digestion and absorption. However, during tube feeding, milk bypasses the nasal and oral cavities, limiting exposure to the smell and taste of milk. Provision of the smell and taste of milk with tube feeds offers a non-invasive and low-cost intervention that, if effective in accelerating the transition to enteral feeds and subsequently to sucking feeds, would bring considerable advantages to infants, their families, and healthcare systems. OBJECTIVES: To assess whether exposure to the smell or taste (or both) of breastmilk or formula administered with tube feeds can accelerate the transition to full sucking feeds without adverse effects in preterm infants. SEARCH METHODS: We conducted searches in CENTRAL, MEDLINE, Embase, CINAHL, and Epistemonikos to 26 April 2023. We also searched clinical trial databases and conference proceedings. SELECTION CRITERIA: We included randomised and quasi-randomised studies that evaluated exposure versus no exposure to the smell or taste of milk (or both) immediately before or at the time of tube feeds. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, assessed risk of bias, and extracted data according to Cochrane Neonatal methodology. We performed meta-analyses using risk ratios (RRs) for dichotomous data and mean differences (MDs) for continuous data, with their respective 95% confidence intervals (CIs). We used GRADE to assess the certainty of evidence. MAIN RESULTS: We included eight studies (1277 preterm infants). Seven studies (1244 infants) contributed data for meta-analysis. The evidence suggests that exposure to the smell and taste of milk with tube feeds has little to no effect on time taken to reach full sucking feeds (MD -1.07 days, 95% CI -2.63 to 0.50; 3 studies, 662 infants; very low-certainty evidence). Two studies reported no adverse effects related to the intervention. The intervention may have little to no effect on duration of parenteral nutrition (MD 0.23 days, 95% CI -0.24 to 0.71; 3 studies, 977 infants; low-certainty evidence), time to reach full enteral feeds (MD -0.16 days, 95% CI -0.45 to 0.12; 1 study, 736 infants; very low-certainty evidence) or risk of necrotising enterocolitis (RR 0.93, 95% CI 0.47 to 1.84; 2 studies, 435 infants; low-certainty evidence), although the evidence for time to reach full enteral feeds is very uncertain. Exposure to the smell and taste of milk with tube feeds probably has little to no effect on risk of late infection (RR 1.14, 95% CI 0.74 to 1.75; 2 studies, 436 infants; moderate-certainty evidence). There were no data available to assess feeding intolerance. The included studies had small sample sizes and methodological limitations, including unclear or lack of randomisation (four studies), lack of blinding of participants and personnel (five studies), unclear or lack of blinding of the outcome assessor (all eight studies), and different inclusion criteria and methods of administering the interventions. AUTHORS' CONCLUSIONS: The results of our meta-analyses suggest that exposure to the smell and taste of milk with tube feeds may have little to no effect on time to reach full sucking feeds and time to reach full enteral feeds. We found no clear difference between exposure and no exposure to the smell or taste of milk on safety outcomes (adverse effects, necrotising enterocolitis, and late infection). Results from one ongoing study and two studies awaiting classification may alter the conclusions of this review. Future research should examine the effect of exposing preterm infants to the smell and taste of milk with tube feeds on health outcomes during hospitalisation, such as attainment of feeding skills, safety, feed tolerance, infection, and growth. Future studies should be powered to detect the effect of the intervention in infants of different gestational ages and on each sex separately. It is also important to determine the optimal method, frequency, and duration of exposure.

Breast Milk Enema and Meconium Evacuation Among Preterm Infants: A Randomized Clinical Trial.

Importance: Delayed meconium evacuation and delayed achievement of full enteral feeding among premature infants are associated with poor short- and long-term outcomes. Identifying a more effective and safer enema for meconium evacuation is imperative for improving neonatal care. Objective: To examine whether breast milk enemas can shorten the time to complete meconium evacuation and achievement of full enteral feeding for preterm infants. Design, Setting, and Participants: This randomized, open-label, parallel-group, single-center clinical trial was conducted from September 1, 2019, to September 30, 2022, among 286 preterm infants with a gestational age of 23 to 30 weeks in the neonatal ward of the Shengjing Hospital of China Medical University in Shenyang. Interventions: Preterm infants were randomly assigned to receive either breast milk enemas or normal saline enemas 48 hours after birth. Main Outcome and Measures: The primary outcomes were time to complete meconium evacuation and time to achieve full enteral feeding. Secondary outcomes were duration of hospitalization, weight at discharge, and duration of total parenteral nutrition. Intention-to-treat and per-protocol analyses were conducted. Results: In total, 286 preterm infants (mean [SD] gestational age, 198.8 [7.9] days; 166 boys [58.0%]) were eligible and included in this study. A total of 145 infants were randomized to the normal saline group, and 141 were randomized to the breast milk group. The time to achieve complete meconium evacuation was significantly shorter in the breast milk group than in the normal saline group (-2.2 days; 95% CI, -3.2 to -1.2 days). The time to achieve full enteral feeding was also significantly shorter in the breast milk group than in the normal saline group (-4.6 days; 95% CI, -8.0 to -1.2 days). The duration of total parenteral nutrition was significantly shorter in the breast milk group than in the normal saline group (-4.6 days; 95% CI, -8.6 to -1.0 days). There were no clinically notable differences in any other secondary or safety outcomes between the 2 groups. Conclusions and Relevance: In this randomized clinical trial testing the effects of breast milk enema on meconium evacuation, breast milk reduced the time to achieve complete meconium evacuation and achieve full enteral feeding for preterm infants with a gestational age of 23 to 30 weeks. Subgroup analyses highlight the need for tailored interventions based on gestational age considerations. Trial Registration: isrctn.org Identifier: ISRCTN17847514.

Consenso sobre criterios y conjunto mínimo de datos para la derivación de pacientes candidatos a teleconsulta de nutrición enteral domiciliaria: proyecto TElENUT / Consensus on criteria and minimum data set for the referral of candidate patients for home enteral nutrition teleconsultation: TELENUT project

Introducción: la teleconsulta es una herramienta asistencial útil en el manejo multidisciplinar de pacientes con indicación de nutrición enteral domiciliaria (NED). El empleo de diferentes herramientas de teleconsulta de NED, como ocurre en el Sistema Andaluz de Salud (SAS), conlleva heterogeneidad en los procesos de derivación entre los servicios de Atención Primaria (AP) y hospitalaria en una misma región. Objetivos: consensuar perfiles de pacientes y conjunto de datos mínimos necesarios para garantizar una derivación adecuada a la teleconsulta de NED, independientemente de la herramienta existente. Estos aspectos consensuados en Andalucía pueden servir de referencia en otras regiones. Métodos: se siguieron tres pasos consecutivos: a) revisión no sistemática de la literatura indexada sobre la teleconsulta en nutrición clínica en España; b) encuesta para conocer la implementación y las necesidades no satisfechas de las herramientas de teleconsulta en los hospitales públicos andaluces; y c) reuniones de trabajo y consenso de 14 profesionales sanitarios de AP (n = 4) y endocrinología y nutrición clínica hospitalaria (n = 10). Resultados: se consensuaron tres formularios de derivación en los que se definieron tres perfiles de pacientes, con el correspondiente conjunto mínimo de datos necesario para solicitar la teleconsulta de NED. El equipo de AP debe proporcionar este conjunto mínimo de datos al especialista en nutrición clínica a través de una herramienta de teleconsulta, implementada en el SAS. Conclusiones: tres formularios consensuados entre profesionales sanitarios involucrados en el proceso de derivación sirven para estandarizar la solicitud de teleconsulta de NED entre equipos asistenciales en función de perfiles de pacientes.(AU)

Introduction: teleconsultation is a useful healthcare tool in the multidisciplinary management of patients with indications of home enteral nutrition (HEN). The use of different teleconsultation platforms, as it happens in the Andalusian Health System (SAS), results in heterogeneous referral processes between Primary Care and hospital services in the same region. Objectives: to establish a consensus on patient profiles and the minimum data set necessary to guarantee an adequate referral to NED teleconsultation regardless of the existing platform. These agreed aspects in Andalusia can serve as a reference in other regions. Methods: three consecutive steps were followed: a) non-systematic review of the indexed literature on teleconsultation in clinical nutrition in Spain; b) survey to know the implementation and unmet needs of teleconsultation platforms in Andalusian public hospitals; and c) working meetings and consensus of 14 health professionals of Primary Care (n = 4) and endocrinology and hospital clinical nutrition (n = 10). Results: three referral forms were agreed in which three patient profiles were defined, with the corresponding minimum set of data necessary to request NED teleconsultation. The Primary Care team should provide this set of data to the clinical nutrition specialist via a teleconsultation platform, implemented in the SAS. Conclusions: three agreed forms between healthcare professionals involved in the referral process serve to standardize the request for teleconsultation of NED between healthcare teams based on patient profiles.(AU)

Medical supervised duodenal-enteral feeding for the treatment of overweight and obesity: MESUDEFT / Nutrición duodenoenteral médicamente supervisada para el tratamiento del sobrepeso y la obesidad: MESUDEFT

Background: the development of specialised nutritional support techniques allows the maintenance of an adequate supply of nutrients in those patients in whom oral feeding is not possible or is insufficient in relation to their requirements, trying to improve the quality of life, especially in those with chronic diseases. Methods: single-center clinical study carried out in a clinical-nutritional center consisting of a medically supervised nasogastric-duodenal tube feeding treatment for overweight, obesity and increased body fat percentage in patients requiring it by means of duodeno-enteral feeding, expecting losses of more than 10 %. Results: twenty-nine patients completed the protocol (20.4 % male and 79.6 % female) with a mean age of 38 years (SD: 12.4); 87.2 kg (SD: 18.5) mean weight; 37.9 kg (SD: 4.8) mean iFat%; 32.4 (SD: 5.4) iMean body mass index (BMI); 100 cm (SD: 16.0) iMean waist; 113.6 cm (SD: 10.4) iMean hip; 33.8 cm (SD: 3.9) iMean upper arm circumference; 65.5 cm (SD: 7.5) iMean thigh circumference; 9.7 (SD: 4.8) iVisceral fat index; and 22.9 days (SD: 13.9) mean treatment. A mean of 22.9 (SD: 13.9) days of MESUDEFT influences weight loss, fat loss, visceral fat loss and decreased arm, hip and thigh circumferences (p < 0.05) (i: initial). Conclusions: MESUDEFT is shown to be an effective alternative as a sole treatment or as an adjunct prior to bariatric surgery for obesity or overweight treatment with a minimum of 10 % loss of BMI and fat mass at completion and 3-6 months follow-up.(AU)

Antecedentes: el desarrollo de técnicas especializadas de soporte nutricional permite mantener un aporte adecuado de nutrientes en aquellos pacientes en los que la alimentación oral no es posible o es insuficiente en relación a sus requerimientos, intentando mejorar la calidad de vida, especialmente de aquellos con enfermedades crónicas. Métodos: estudio clínico unicéntrico prospectivo realizado en un centro clínico-nutricional consistente en un tratamiento con alimentación por sonda nasogástrica-duodenal médicamente supervisado para el sobrepeso, la obesidad y el aumento del porcentaje de grasa corporal en pacientes que lo requieran mediante alimentación duodenoenteral, durante un mes aproximado, con previsión de pérdidas superiores al 10 % y con control posterior entre los tres y los seis meses siguientes. Resultados: veintinueve pacientes completaron el protocolo (20,4 % varones y 79,6 % mujeres) con una edad media de 38 años (DE: 12,4); 87,2 kg (DE: 18,5) iPeso medio; 37,9 kg (DE: 4,8) iGrasa% media; 32,4 (DE: 5,4) iIMC medio; 100 cm (DE: 16,0) iCintura media; 113,6 cm (DE: 10,4) iCadera media; 33,8 cm (DE: 3,9) iCircunferencia braquial media; 65,5 cm (DE: 7,5) circunferencia muslo media; 9,7 (DE: 4,8) iíndice de grasa visceral; y 22,9 días (DE: 13,9) de tratamiento medio. Una media de 22,9 (DE: 13,9) días de MESUDEFT influye en la pérdida de peso, la pérdida de grasa, la pérdida de grasa visceral y la disminución de las circunferencias del brazo, la cadera y el muslo (p < 0,05) (i: inicial). Conclusiones: MESUDEFT se muestra como una alternativa eficaz como tratamiento único o como coadyuvante previo a la cirugía bariátrica de la obesidad o tratamiento del sobrepeso con una pérdida mínima del 10 % del índice de masa corporal (IMC) y de la masa grasa al finalizar y con control durante los siguientes 3-6 meses.(AU)

Influencia de la adaptación dietética individualizada en pacientes sometidos atrasplante de precursores hematopoyéticos / Estudio aDiTraS Infl uence of individualized dietary adaptation in patients undergoing hematopoietic stem cell transplantation. The ADITRAS study

Introducción: el objetivo del estudio fue valorar la eficacia de una adaptación dietética individualizada para conseguir los requerimientos nutricionales en pacientes sometidos a trasplante de precursores hematopoyéticos (TPH). Metodología: estudio piloto de intervención nutricional con pacientes sometidos a TPH. Se realizó una valoración nutricional en las primeras 24 horas de ingreso y cada 48 a 72 horas hasta el alta, o + 40 días del trasplante, realizando adaptaciones dietéticas. Resultados: se reclutaron 25 pacientes. Según el MUST, el 92,0 % (n = 23) se encontraban bien nutridos en la visita inicial, con una pérdida de 2,1 (3,8) kg y un IMC de 26,4 kg/m2 (4,2). Antes del TPH ya hubo una disminución de la ingesta del 15,4 (23,5) % y del peso corporal de 0,2 (3,2) kg; tras el TPH, la pérdida de peso fue de 3,4 (5,0) kg y la disminución de la ingesta del 6,5 (30,4) %. Los síntomas predominantes fueron mucositis (60 %), náuseas (60 %) y diarrea (44 %). Se adaptó la dieta en el 100 % de los pacientes y el 52 % recibieron soporte nutricional oral (SNO) (n = 13), mientras que la nutrición enteral (NE) y la nutrición parenteral (NP) se utilizaron solo 1 vez. Conclusión: el estado nutricional de los pacientes sometidos a TPH es normal al ingreso pero se deteriora durante la realización del trasplante y su acondicionamiento previo. La intervención dietética es clave para mantener la ingesta oral y disminuir el riesgo de desnutrición.(AU)

Introduction: the objective of the study was to assess the effi cacy of an individualized dietary adaptation to achieve nutritional requirements in patients undergoing hematopoietic stem cell transplantation (HSCT). Methodology: a pilot study of a nutritional intervention in patients undergoing HSCT. A nutritional assessment was performed the fi rst 24 hours of admission and every 48-72 hours until discharge, or + 40 days after the transplant, making dietary adaptations. Results: 25 patients were recruited. According to MUST, 92.0 % (n = 23) were well nourished at the initial visit, with a loss of 2.1 (3.8) kg and a BMI of 26.4 kg/m2 (4.2). Before HSCT, there was already a decrease in intake of 15.4 (23.5) % and in body weight of 0.2 (3.2) kg; after the HSCT, the weight loss was 3.4 (5.0) kg and the decrease in intake was 6.5 (30.4) %. The predominant symptoms were mucositis (60 %), nausea (60 %), and diarrhea (44 %). The diet was adapted in 100 % of the patients, 52 % received oral nutritional support (ONS) (n = 13); enteral nutrition (EN) and parenteral nutrition (PN) were used only once. Conclusion: the nutritional status of patients undergoing HSCT is normal on admission but deteriorates during transplantation and prior conditioning. Dietary intervention is key to maintaining oral intake and reducing the risk of malnutrition.(AU)

Preoperative nutrition therapy in people undergoing gastrointestinal surgery.

BACKGROUND: Poor preoperative nutritional status has been consistently linked to an increase in postoperative complications and worse surgical outcomes. We updated a review first published in 2012. OBJECTIVES: To assess the effects of preoperative nutritional therapy compared to usual care in people undergoing gastrointestinal surgery. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, three other databases and two trial registries on 28 March 2023. We searched reference lists of included studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of people undergoing gastrointestinal surgery and receiving preoperative nutritional therapy, including parenteral nutrition, enteral nutrition or oral nutrition supplements, compared to usual care. We only included nutritional therapy that contained macronutrients (protein, carbohydrate and fat) and micronutrients, and excluded studies that evaluated single nutrients. We included studies regardless of the nutritional status of participants, that is, well-nourished participants, participants at risk of malnutrition, or mixed populations. We excluded studies in people undergoing pancreatic and liver surgery. Our primary outcomes were non-infectious complications, infectious complications and length of hospital stay. Our secondary outcomes were nutritional aspects, quality of life, change in macronutrient intake, biochemical parameters, 30-day perioperative mortality and adverse effects. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodology. We assessed risk of bias using the RoB 1 tool and applied the GRADE criteria to assess the certainty of evidence. MAIN RESULTS: We included 16 RCTs reporting 19 comparisons (2164 participants). Seven studies were new for this update. Participants' ages ranged from 21 to 79 years, and 62% were men. Three RCTs used parenteral nutrition, two used enteral nutrition, eight used immune-enhancing nutrition and six used standard oral nutrition supplements. All studies included mixed groups of well-nourished and malnourished participants; they used different methods to identify malnutrition and reported this in different ways. Not all the included studies were conducted within an Enhanced Recovery After Surgery (ERAS) programme, which is now current clinical practice in most hospitals undertaking GI surgery. We were concerned about risk of bias in all the studies and 14 studies were at high risk of bias due to lack of blinding. We are uncertain if parenteral nutrition has any effect on the number of participants who had a non-infectious complication (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.36 to 1.02; 3 RCTs, 260 participants; very low-certainty evidence); infectious complication (RR 0.98, 95% CI 0.53 to 1.80; 3 RCTs, 260 participants; very low-certainty evidence) or length of hospital stay (mean difference (MD) 5.49 days, 95% CI 0.02 to 10.96; 2 RCTs, 135 participants; very low-certainty evidence). None of the enteral nutrition studies reported non-infectious complications as an outcome. The evidence is very uncertain about the effect of enteral nutrition on the number of participants with infectious complications after surgery (RR 0.90, 95% CI 0.59 to 1.38; 2 RCTs, 126 participants; very low-certainty evidence) or length of hospital stay (MD 5.10 days, 95% CI -1.03 to 11.23; 2 RCTs, 126 participants; very low-certainty evidence). Immune-enhancing nutrition compared to controls may result in little to no effect on the number of participants experiencing a non-infectious complication (RR 0.79, 95% CI 0.62 to 1.00; 8 RCTs, 1020 participants; low-certainty evidence), infectious complications (RR 0.74, 95% CI 0.53 to 1.04; 7 RCTs, 925 participants; low-certainty evidence) or length of hospital stay (MD -1.22 days, 95% CI -2.80 to 0.35; 6 RCTs, 688 participants; low-certainty evidence). Standard oral nutrition supplements may result in little to no effect on number of participants with a non-infectious complication (RR 0.90, 95% CI 0.67 to 1.20; 5 RCTs, 473 participants; low-certainty evidence) or the length of hospital stay (MD -0.65 days, 95% CI -2.33 to 1.03; 3 RCTs, 299 participants; low-certainty evidence). The evidence is very uncertain about the effect of oral nutrition supplements on the number of participants with an infectious complication (RR 0.88, 95% CI 0.60 to 1.27; 5 RCTs, 473 participants; very low-certainty evidence). Sensitivity analysis based on malnourished and weight-losing participants found oral nutrition supplements may result in a slight reduction in infections (RR 0.58, 95% CI 0.40 to 0.85; 2 RCTs, 184 participants). Studies reported some secondary outcomes, but not consistently. Complications associated with central venous catheters occurred in RCTs involving parenteral nutrition. Adverse events in the enteral nutrition, immune-enhancing nutrition and standard oral nutrition supplements RCTs included nausea, vomiting, diarrhoea and abdominal pain. AUTHORS' CONCLUSIONS: We were unable to determine if parenteral nutrition, enteral nutrition, immune-enhancing nutrition or standard oral nutrition supplements have any effect on the clinical outcomes due to very low-certainty evidence. There is some evidence that standard oral nutrition supplements may have no effect on complications. Sensitivity analysis showed standard oral nutrition supplements probably reduced infections in weight-losing or malnourished participants. Further high-quality multicentre research considering the ERAS programme is required and further research in low- and middle-income countries is needed.

Nutritional Support for Moderate-to-Late-Preterm Infants - A Randomized Trial.

BACKGROUND: Most moderate-to-late-preterm infants need nutritional support until they are feeding exclusively on their mother's breast milk. Evidence to guide nutrition strategies for these infants is lacking. METHODS: We conducted a multicenter, factorial, randomized trial involving infants born at 32 weeks 0 days' to 35 weeks 6 days' gestation who had intravenous access and whose mothers intended to breast-feed. Each infant was assigned to three interventions or their comparators: intravenous amino acid solution (parenteral nutrition) or dextrose solution until full feeding with milk was established; milk supplement given when maternal milk was insufficient or mother's breast milk exclusively with no supplementation; and taste and smell exposure before gastric-tube feeding or no taste and smell exposure. The primary outcome for the parenteral nutrition and the milk supplement interventions was the body-fat percentage at 4 months of corrected gestational age, and the primary outcome for the taste and smell intervention was the time to full enteral feeding (150 ml per kilogram of body weight per day or exclusive breast-feeding). RESULTS: A total of 532 infants (291 boys [55%]) were included in the trial. The mean (±SD) body-fat percentage at 4 months was similar among the infants who received parenteral nutrition and those who received dextrose solution (26.0±5.4% vs. 26.2±5.2%; adjusted mean difference, -0.20; 95% confidence interval [CI], -1.32 to 0.92; P = 0.72) and among the infants who received milk supplement and those who received mother's breast milk exclusively (26.3±5.3% vs. 25.8±5.4%; adjusted mean difference, 0.65; 95% CI, -0.45 to 1.74; P = 0.25). The time to full enteral feeding was similar among the infants who were exposed to taste and smell and those who were not (5.8±1.5 vs. 5.7±1.9 days; P = 0.59). Secondary outcomes were similar across interventions. Serious adverse events occurred in one infant. CONCLUSIONS: This trial of routine nutrition interventions to support moderate-to-late-preterm infants until full nutrition with mother's breast milk was possible did not show any effects on the time to full enteral feeding or on body composition at 4 months of corrected gestational age.

Gut metabolome and microbiota signatures predict response to treatment with exclusive enteral nutrition in a prospective study in children with active Crohn's disease.

BACKGROUND: Predicting response to exclusive enteral nutrition (EEN) in active Crohn's disease (CD) could lead to therapy personalization and pretreatment optimization. OBJECTIVES: This study aimed to explore the ability of pretreatment parameters to predict fecal calprotectin (FCal) levels at EEN completion in a prospective study in children with CD. METHODS: In children with active CD, clinical parameters, dietary intake, cytokines, inflammation-related blood proteomics, and diet-related metabolites, metabolomics and microbiota in feces, were measured before initiation of 8 wk of EEN. Prediction of FCal levels at EEN completion was performed using machine learning. Data are presented with medians (IQR). RESULTS: Of 37 patients recruited, 15 responded (FCal < 250 µg/g) to EEN (responders) and 22 did not (nonresponders). Clinical and immunological parameters were not associated with response to EEN. Responders had lesser (µmol/g) butyrate [responders: 13.2 (8.63-18.4) compared with nonresponders: 22.3 (12.0-32.0); P = 0.03], acetate [responders: 49.9 (46.4-68.4) compared with nonresponders: 70.4 (57.0-95.5); P = 0.027], phenylacetate [responders: 0.175 (0.013-0.611) compared with nonresponders: 0.943 (0.438-1.35); P = 0.021], and a higher microbiota richness [315 (269-347) compared with nonresponders: 243 (205-297); P = 0.015] in feces than nonresponders. Responders consumed (portions/1000 kcal/d) more confectionery products [responders: 0.55 (0.38-0.72) compared with nonresponders: 0.19 (0.01-0.38); P = 0.045]. A multicomponent model using fecal parameters, dietary data, and clinical and immunological parameters predicted response to EEN with 78% accuracy (sensitivity: 80%; specificity: 77%; positive predictive value: 71%; negative predictive value: 85%). Higher taxon abundance from Ruminococcaceae, Lachnospiraceae, and Bacteroides and phenylacetate, butyrate, and acetate were the most influential variables in predicting lack of response to EEN. CONCLUSIONS: We identify microbial signals and diet-related metabolites in feces, which could comprise targets for pretreatment optimization and personalized nutritional therapy in pediatric CD.

Nutritional support during the first week for infants with bronchopulmonary dysplasia and respiratory distress: a multicenter cohort study in China.

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a major complication affecting the survival rate and long-term outcomes of preterm infants. A large, prospective, multicenter cohort study was conducted to evaluate early nutritional support during the first week of life for preterm infants with a gestational age < 32 weeks and to verify nutritional risk factors related to BPD development. METHODS: A prospective multicenter cohort study of very preterm infants was conducted in 40 tertiary neonatal intensive care units across mainland China between January 1, 2020, and December 31, 2021. Preterm infants who were born at a gestational age < 32 weeks, < 72 h after birth and had a respiratory score > 4 were enrolled. Antenatal and postnatal information focusing on nutritional parameters was collected through medical systems. Statistical analyses were also performed to identify BPD risk factors. RESULTS: The primary outcomes were BPD and severity at 36 weeks postmenstrual age. A total of 1410 preterm infants were enrolled in this study. After applying the exclusion criteria, the remaining 1286 infants were included in this analysis; 614 (47.7%) infants were in the BPD group, and 672 (52.3%) were in the non-BPD group. In multivariate logistic regression model, the following six factors were identified of BPD: birth weight (OR 0.99, 95% CI 0.99-0.99; p = 0.039), day of full enteral nutrition (OR 1.03, 95% CI 1.02-1.04; p < 0.001), parenteral protein > 3.5 g/kg/d during the first week (OR 1.65, 95% CI 1.25-2.17; p < 0.001), feeding type (formula: OR 3.48, 95% CI 2.21-5.49; p < 0.001, mixed feed: OR 1.92, 95% CI 1.36-2.70; p < 0.001; breast milk as reference), hsPDA (OR 1.98, 95% CI 1.44-2.73; p < 0.001), and EUGR ats 36 weeks (OR 1.40, 95% CI 1.02-1.91; p = 0.035). CONCLUSIONS: A longer duration to achieve full enteral nutrition in very preterm infants was associated with increased BPD development. Breastfeeding was demonstrated to have a protective effect against BPD. Early and rapidly progressive enteral nutrition and breastfeeding should be promoted in very preterm infants. TRIAL REGISTRATION: The trial was registered in the Chinese Clinical Trial Registry (No. ChiCTR2000030125 on 24/02/2020) and in www.ncrcch.org (No. ISRCTN84167642 on 25/02/2020).

Pre-Diagnosis Diet Predicts Response to Exclusive Enteral Nutrition and Correlates with Microbiome in Pediatric Crohn Disease.

Exclusive enteral nutrition (EEN) is effective in inducing remission in pediatric Crohn disease (CD). EEN alters the intestinal microbiome, but precise mechanisms are unknown. We hypothesized that pre-diagnosis diet establishes a baseline gut microbiome, which then mediates response to EEN. We analyzed prospectively recorded food frequency questionnaires (FFQs) for pre-diagnosis dietary patterns. Fecal microbiota were sequenced (16SrRNA) at baseline and through an 18-month follow-up period. Dietary patterns, Mediterranean diet adherence, and stool microbiota were associated with EEN treatment outcomes, disease flare, need for anti-tumor necrosis factor (TNF)-α therapy, and long-term clinical outcomes. Ninety-eight patients were included. Baseline disease severity and microbiota were associated with diet. Four dietary patterns were identified by FFQs; a "mature diet" high in fruits, vegetables, and fish was linked to increased baseline microbial diversity, which was associated with fewer disease flares (p < 0.05) and a trend towards a delayed need for anti-TNF therapy (p = 0.086). Baseline stool microbial taxa were increased (Blautia and Faecalibacterium) or decreased (Ruminococcus gnavus group) with the mature diet compared to other diets. Surprisingly, a "pre-packaged" dietary pattern (rich in processed foods) was associated with delayed flares in males (p < 0.05). Long-term pre-diagnosis diet was associated with outcomes of EEN therapy in pediatric CD; diet-microbiota and microbiota-outcome associations may mediate this relationship.

Tumor Seeding Post Nutritional Support Implementation: A Rare Complication; A Scoping Review.

Patients with cancer are at risk of malnutrition because of reduced food intake, thus making oral intake challenging. Thus, nutritional support is used to provide the nutrient requirements. Feeding tube site implantation among patients with cancer has been reported after endoscopic feeding gastrostomy installation. This manuscript aims to further explore this phenomenon using a structured database review. Among 33 seeding cases included in this review, case reports (70 %) were the most common study design, predominantly using percutaneous endoscopic gastrostomy via the pull method. The duration between tube implantation and seeding detection ranged from 7.12 ± 3.7 months, with some missing data among the included studies. The most common primary cancer diagnosis was head and neck cancer. Tumor seeding was higher among male patients than that in female patients. However, large-scale, statistically powered studies are needed to further investigate this complication.

Evaluation of community nurse-led traumatic tube displacements.

Home enteral tube feeding (HEF) has many benefits and is largely safe practice. Some complications have historically required intervention in the acute setting, including traumatic displacement of feeding tubes (i.e. internal bumper/balloon removed intact), and evidence to support the safe replacement of these tubes in the community is lacking. To address this, a service enabling community homecare nurses (CHN) to replace traumatically displaced feeding tubes was designed and evaluated. Adult patients presenting with a traumatically displaced feeding tube over 29 months were included in the service evaluation. Baseline characteristics and outcomes at day 1, 7 and 6 months post-replacement were recorded. A total of 71 tube replacements were performed by CHNs in 60 patients. No clinical complications were recorded at any follow-up points. A simple cost analysis estimated savings of £235 754.40. These results suggest that nurse-led replacement of traumatically displaced feeding tubes in adults in the community is low-risk and offers potential cost savings.
