Abstract
OBJECTIVES To review the current literature and develop consensus conclusions and recommendations on nutrient intakes and nutritional practice in preterm infants with birthweight <1800 g. METHODS The European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Committee of Nutrition (CoN) led a process that included CoN members and invited experts. Invited experts with specific expertise were chosen to represent as broad a geographical spread as possible. A list of topics was developed, and individual leads were assigned to topics along with other members, who reviewed the current literature. A single face-to-face meeting was held in February 2020. Provisional conclusions and recommendations were developed between 2020 and 2021, and these were voted on electronically by all members of the working group between 2021 and 2022. Where >90% consensus was not achieved, online discussion meetings were held, along with further voting until agreement was reached. RESULTS In general, there is a lack of strong evidence for most nutrients and topics. The summary paper is supported by additional supplementary digital content that provide a fuller explanation of the literature and relevant physiology: introduction and overview; human milk reference data; intakes of water, protein, energy, lipid, carbohydrate, electrolytes, minerals, trace elements, water soluble vitamins, and fat soluble vitamins; feeding mode including mineral enteral feeding, feed advancement, management of gastric residuals, gastric tube placement and bolus or continuous feeding; growth; breastmilk buccal colostrum, donor human milk, and risks of cytomegalovirus infection; hydrolyzed protein and osmolality; supplemental bionutrients; and use of breastmilk fortifier. CONCLUSIONS We provide updated ESPGHAN CoN consensus-based conclusions and recommendations on nutrient intakes and nutritional management for preterm infants.

Abstract
Purpose: To compare nutrition and health outcomes before and after implementing a standardized enteral feeding protocol on nutrition and health outcomes in very low birth weight preterm infants.Methods: A retrospective chart review was performed evaluating preterm infants, born less than 34 weeks gestation and weighing less than 1500 g, before and after the implementation of a standardized enteral feeding protocol. Outcomes included weaning of parenteral nutrition, initiation and advancement of enteral feeds, initiation of human-milk fortifier (HMF), change in weight z-score and neonatal morbidities.Results: Fifty-six infants (30 in pre-group, 26 in post-group) met the inclusion criteria. Infants in the standardized enteral feeding protocol group started enteral feeds earlier (p = 0.039) and received full HMF fortification at lower weights (p = 0.033) than those in the pre-group. Fewer days on continuous positive airway pressure (p = 0.021) and lower rates of bronchopulmonary dysplasia (p = 0.018) were also observed in the post-group. Weaning of parenteral nutrition and weight z-score were not significantly different between groups. There were no differences in other morbidities.Conclusion: Study results suggest that adopting a standardized enteral feeding protocol may promote early initiation of enteral feeds and fortification.

Abstract
Necrotizing enterocolitis (NEC) is an inflammatory disease affecting premature infants. Intestinal microbial composition may play a key role in determining which infants are predisposed to NEC and when infants are at highest risk of developing NEC. It is unclear how to optimize antibiotic therapy in preterm infants to prevent NEC and how to optimize antibiotic regimens to treat neonates with NEC. This article discusses risk factors for NEC, how dysbiosis in preterm infants plays a role in the pathogenesis of NEC, and how probiotic and antibiotic therapy may be used to prevent and/or treat NEC and its sequelae.

Risk of Necrotizing Enterocolitis Following Packed Red Blood Cell Transfusion in Very Low Birth Weight Infants. Indian J Pediatr 2019; 86:347-353. [PMID: 30790187 DOI: 10.1007/s12098-019-02887-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Accepted: 01/25/2019] [Indexed: 01/01/2023]
Abstract
OBJECTIVE To evaluate the association between red blood cell (RBC) transfusion leading to necrotizing enterocolitis (NEC) within 48 h, known as transfusion-associated necrotizing enterocolitis (TANEC). METHODS A nested case-control study using historical data was conducted in the neonatal intensive care unit of Songklanagarind Hospital, Thailand. All very low birth weight (VLBW) infants delivered between November 2009 and July 2016 were enrolled. The infants were identified as RBC transfusion received and NEC developed. Logistic regression was used to evaluate risk factors for transfusion and the association between RBC transfusion and NEC. RESULTS Four hundred and forty-four VLBW infants were enrolled in the study. The median (interquartile range) gestational age was 29 (27, 31) wk. The overall incidence of NEC was 13%. Three (5.2%) of the NEC infants had TANEC. The infants who received RBC transfusion had a lower gestational age [odds ratio, OR 0.64; 95% confidence interval (95%CI) 0.57, 0.73, p < 0.001] and were more likely to have pneumonia (OR 9.86; 95%CI 5.02, 19.35, p < 0.001) or to have received H2 blocker (OR 2.92; 95%CI 1.73, 4.93, p < 0.001). The ORs (95% CI) after adjusting for confounders, the association between RBC transfusion and NEC for transfusions ≤2 d, >2 to 4 d, and > 4 to 6 d prior to NEC were 1.83 (0.41, 8.16; p = 0.43), 1.7 (0.26, 11.16; p = 0.58) and 1.19 (0.31, 4.62; p = 0.80) respectively. CONCLUSIONS After controlling of confounders, no evidence of association was found between RBC transfusion and TANEC.

NEC-zero recommendations from scoping review of evidence to prevent and foster timely recognition of necrotizing enterocolitis. Matern Health Neonatol Perinatol 2017; 3:23.

Abstract
BACKGROUND Although decades have focused on unraveling its etiology, necrotizing enterocolitis (NEC) remains a chief threat to the health of premature infants. Both modifiable and non-modifiable risk factors contribute to varying rates of disease across neonatal intensive care units (NICUs). PURPOSE The purpose of this paper is to present a scoping review with two new meta-analyses, clinical recommendations, and implementation strategies to prevent and foster timely recognition of NEC. METHODS Using the Translating Research into Practice (TRIP) framework, we conducted a stakeholder-engaged scoping review to classify strength of evidence and form implementation recommendations using GRADE criteria across subgroup areas: 1) promoting human milk, 2) feeding protocols and transfusion, 3) timely recognition strategies, and 4) medication stewardship. Sub-groups answered 5 key questions, reviewed 11 position statements and 71 research reports. Meta-analyses with random effects were conducted on effects of standardized feeding protocols and donor human milk derived fortifiers on NEC. RESULTS Quality of evidence ranged from very low (timely recognition) to moderate (feeding protocols, prioritize human milk, limiting antibiotics and antacids). Prioritizing human milk, feeding protocols and avoiding antacids were strongly recommended. Weak recommendations (i.e. "probably do it") for limiting antibiotics and use of a standard timely recognition approach are presented. Meta-analysis of data from infants weighing <1250 g fed donor human milk based fortifier had reduced odds of NEC compared to those fed cow's milk based fortifier (OR = 0.36, 95% CI 0.13, 1.00; p = 0.05; 4 studies, N = 1164). Use of standardized feeding protocols for infants <1500 g reduced odds of NEC by 67% (OR = 0.33, 95% CI 0.17, 0.65, p = 0.001; 9 studies; N = 4755 infants). Parents recommended that NEC information be shared early in the NICU stay, when feedings were adjusted, or feeding intolerance occurred via print and video materials to supplement verbal instruction. DISCUSSION Evidence for NEC prevention is of sufficient quality to implement. Implementation that addresses system-level interventions that engage the whole team, including parents, will yield the best impact to prevent NEC and foster its timely recognition.

Abstract
PURPOSE Parenteral nutrition (PN)-associated cholestasis (PNAC) is one of the most common complications in very low birth weight infants (VLBWIs). The aim of this study is to evaluate the risk factors of PNAC in VBLWIs. METHODS We retrospectively reviewed the medical records of 322 VLBWIs admitted to the neonatal intensive care unit of our hospital from July 1, 2009 to December 31, 2013. We excluded 72 dead infants; 6 infants were transferred to another hospital, and 57 infants were transferred to our hospital at 2 weeks after birth. The infants were divided into the cholestasis and the non-cholestasis groups. PNAC was defined as a direct bilirubin level of ≥2.0 mg/dL in infants administered with PN for ≥2 weeks. RESULTS A total of 187 VLBWI were enrolled in this study; of these, 46 infants developed PNAC. Multivariate logistic regression analysis showed that the risk factors of PNAC in VLBWI were longer duration of antimicrobial use (odds ratio [OR] 4.49, 95% confidence interval [95% CI] 4.42-4.58), longer duration of PN (OR 2.68, 95% CI 2.41-3.00), long-term lack of enteral nutrition (OR 2.89, 95% CI 2.43-3.37), occurrence of necrotizing enterocolitis (OR 2.40, 95% CI 2.16-2.83), and gastrointestinal operation (OR 2.19, 95% CI 2.03-2.58). CONCLUSION The results of this study suggest that shorter PN, aggressive enteral nutrition, and appropriate antimicrobial use are important strategies in preventing PNAC.

Abstract
BACKGROUND AND OBJECTIVES Many observational studies reporting a temporal association between red cell transfusions (RBCTs) and necrotizing enterocolitis (NEC) in preterm infants fail to take into account RBCTs in infants without NEC. The objective of this study was to investigate the association between RBCTs and NEC in an analytical retrospective cohort study with minimization of selection and measurement bias and controlling for clinical covariates. METHODS Inborn preterm infants [23-32 weeks gestational age (GA)] without major congenital anomalies were eligible. Association of RBCT and modified Bell's Stage ≥2A NEC was explored using bivariate analyses and verified using multivariable Cox regression. RESULTS Of 627 eligible infants, 305 neither received RBCT nor developed NEC and 12 developed NEC prior to RBCT. Of 310 infants with RBCT, 27 developed NEC. Compared to infants without NEC, infants with NEC received significantly lower number of RBCTs before diagnosis of NEC (p = 0.000). On multivariable Cox regression controlling for clinical covariates, dichotomous RBCT exposure was associated with 60% reduced hazard for NEC. CONCLUSIONS RBCT exposure was associated with decreased hazards for NEC in preterm infants in this study; factors previously reported to be associated with NEC remained statistically significant predictors.
