[PMID: 37639741 DOI: 10.1016/j.clnu.2023.07.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 07/21/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND & AIMS In 2016, ESPEN published the guideline for Chronic Intestinal Failure (CIF) in adults. An updated version of ESPEN guidelines on CIF due to benign disease in adults was devised in order to incorporate new evidence since the publication of the previous ESPEN guidelines. METHODS The grading system of the Scottish Intercollegiate Guidelines Network (SIGN) was used to grade the literature. Recommendations were graded according to the levels of evidence available as A (strong), B (conditional), 0 (weak) and Good practice points (GPP). The recommendations of the 2016 guideline (graded using the GRADE system) which were still valid, because no studies supporting an update were retrieved, were reworded and re-graded accordingly. RESULTS The recommendations of the 2016 guideline were reviewed, particularly focusing on definitions, and new chapters were included to devise recommendations on IF centers, chronic enterocutaneous fistulas, costs of IF, caring for CIF patients during pregnancy, transition of patients from pediatric to adult centers. The new guideline consist of 149 recommendations and 16 statements which were voted for consensus by ESPEN members, online in July 2022 and at conference during the annual Congress in September 2022. The Grade of recommendation is GPP for 96 (64.4%) of the recommendations, 0 for 29 (19.5%), B for 19 (12.7%), and A for only five (3.4%). The grade of consensus is "strong consensus" for 148 (99.3%) and "consensus" for one (0.7%) recommendation. The grade of consensus for the statements is "strong consensus" for 14 (87.5%) and "consensus" for two (12.5%). CONCLUSIONS It is confirmed that CIF management requires complex technologies, multidisciplinary and multiprofessional activity, and expertise to care for the underlying gastrointestinal disease and to provide HPN support. Most of the recommendations were graded as GPP, but almost all received a strong consensus.

Abstract
Establishing full enteral nutrition in critically ill preterm infants with immature gastrointestinal function is challenging. In this article, we will summarize emerging clinical evidence from randomized clinical trials suggesting the feasibility and efficacy of feeding interventions targeting the early establishment of full enteral nutrition. We will also examine trial outcomes of higher volume feedings after the establishment of full enteral nutrition. Only data from randomized clinical trials will be discussed extensively. Future opportunities for clinical research will also be presented.

How to Provide Breast Milk for the Preterm Infant and Avoid Symptomatic Cytomegalovirus Infection with Possible Long-Term Sequelae. Life (Basel) 2022; 12:life12040504. [PMID: 35454995 PMCID: PMC9031638 DOI: 10.3390/life12040504] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 03/25/2022] [Accepted: 03/26/2022] [Indexed: 12/04/2022] Open
Abstract
Cytomegalovirus (CMV) is able to replicate in the breast milk of lactating mothers and thus the offspring might be affected by mild to severe symptoms of postnatal CMV disease in case of prematurity; not in term infants. Sepsis-like syndrome affects only very low birth infants; and few cases have been reported. The neurodevelopmental long-term outcome of those preterm infants revealed possible subtle deficiencies, but no major neurodevelopmental impairment. Neurodevelopmental sequelae are still in discussion and seem somewhat overestimated after careful evaluation of the published evidence. The main focus of postnatal CMV disease lies upon the extremely low birth weight of infants. Elimination of CMV is provided by short-term heating methods like the most widely used Holder pasteurization. Freezing and thawing methods leave a risk for CMV acquisition. The benefits of untreated breast milk have to be considered to outweigh the possible sequelae of postnatal CMV infection in the most vulnerable preterm infants.

Abstract
BACKGROUND Delayed onset of minimal enteral nutrition compromises the immune response of preterm infants, increasing the risk of colonization and clinical complications (e.g., late-onset sepsis). This study aimed to analyze associations between late-onset sepsis in very low birth weight infants (<1500 g) and days of parenteral nutrition, days to reach full enteral nutrition, and maternal and nutritional factors. METHODS A cross-sectional study was carried out with very low birth weight infants admitted to a neonatal intensive care unit (NICU) of a reference maternity hospital of high-risk deliveries. Data regarding days of parenteral nutrition, days to reach full enteral nutrition, fasting days, extrauterine growth restriction, and NICU length of stay were extracted from online medical records. Late-onset sepsis was diagnosed (clinical or laboratory) after 48 h of life. Chi-squared, Mann-Whitney tests, and binary logistic regression were applied. RESULTS A total of 97 preterm infants were included. Of those, 75 presented late-onset sepsis with clinical (n = 40) or laboratory (n = 35) diagnosis. Maternal urinary tract infection, prolonged parenteral nutrition (>14 days), and extrauterine growth restriction presented 4.24-fold, 4.86-fold, and 4.90-fold higher chance of late-onset sepsis, respectively. CONCLUSION Very low birth weight infants with late-onset sepsis had prolonged parenteral nutrition and took longer to reach full enteral nutrition. They also presented a higher prevalence of extrauterine growth restriction than infants without late-onset sepsis.

Abstract
BACKGROUND & AIMS Feeding intolerance (FI) is a common phenomenon experienced in preterm infants in neonatal intensive care units, as well as being a focus of many research studies into feeding methods, particularly in relation to comorbidities. There is no widely accepted definition of FI. This systematic review aimed to explore the range of definitions used for FI and provide an estimate of the prevalence amongst preterm infants. METHODS Searches were completed on MEDLINE (includes the Cochrane library), Embase, PsycInfo, CINAHL, NHS Evidence and Web of Science. Inclusion criteria; preterm infants in neonatal units, a clear definition of FI, >10 patients and be available in English language. Case reports were excluded. RESULTS One hundred studies were included. Definitions of FI were inconsistent. Studies were grouped according to definition used into: Group A - measuring gastric residual volume (GRV) only; group B - GRV and abdominal distension (AD); group C - GRV, AD and gastrointestinal symptoms (GI) which included any of vomiting, bilious vomiting and blood in stool; group D- GRV and GI; group E - AD and GI; group F - GI only and group G - any other elements used. Meta-analysis demonstrated that prevalence of FI between groups varied from 15 to 30% with an overall prevalence of 27% (95% confidence interval 23-31%). Group A had the highest prevalence. Review of time to full enteral feed was performed (37 studies) which demonstrated a range of 11.3-18.3 days depending on which FI definition used. DISCUSSION Definitions of FI in research are inconsistent, a similar finding to that seen in studies in both paediatric and adult critical care populations. The difficulty of defining FI in the preterm population is the concern regarding necrotising enterocolitis, with some studies using an overlap in their definitions, despite differing pathophysiology and management. Due to the heterogeneity of data obtained in this review regarding definitions used, further robust research is required in order to conclude which elements which should be used to define FI in this population.

Abstract
BACKGROUND There is presently no certainty about the ideal feeding intervals for preterm infants. Shorter feeding intervals of, for example, two hours, have the theoretical advantage of allowing smaller volumes of milk. This may have the potential to reduce the incidence and severity of gastro-oesophageal reflux. Longer feeding intervals have the theoretical advantage of allowing more gastric emptying between two feeds. This potentially provides periods of rest (and thus less hyperaemia) for an immature digestive tract. OBJECTIVES To determine the safety of shorter feeding intervals (two hours or shorter) versus longer feeding intervals (three hours or more) and to compare the effects in terms of days taken to regain birth weight and to achieve full feeding. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to run comprehensive searches in CENTRAL (2020, Issue 6) and Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions, and CINAHL on 25 June 2020. We searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We included RCTs and quasi-RCTs comparing short (e.g. one or two hours) versus long (e.g. three or four hours) feeding intervals in preterm infants of any birth weight, all or most of whom were less than 32 weeks' gestation. Infants could be of any postnatal age at trial entry, but eligible infants should not have received feeds before study entry, with the exception of minimal enteral feeding. We included studies of nasogastric or orogastric bolus feeding, breast milk or formula, in which the feeding interval is the intervention. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We used the GRADE approach to assess the certainty of evidence. Our primary outcomes were days taken to achieve full enteral feeding and days to regain birth weight. Our other outcomes were duration of hospital stay, episodes of necrotising enterocolitis (NEC) and growth during hospital stay (weight, length and head circumference). MAIN RESULTS We included four RCTs, involving 417 infants in the review. One study involving 350 infants is awaiting classification. All studies compared two-hourly versus three-hourly feeding interval. The risk of bias of the included studies was generally low, but all studies had high risk of performance bias due to lack of blinding of the intervention. Three studies were included in meta-analysis for the number of days taken to achieve full enteral feeding (351 participants). The mean days to achieve full feeds was between eight and 11 days. There was little or no difference in days taken to achieve full enteral feeding between two-hourly and three-hourly feeding, but this finding was of low certainty (mean difference (MD) ‒0.62, 95% confidence interval (CI) ‒1.60 to 0.36). There was low-certainty evidence that the days taken to regain birth weight may be slightly longer in infants receiving two-hourly feeding than in those receiving three-hourly feeding (MD 1.15, 95% CI 0.11 to 2.20; 3 studies, 350 participants). We are uncertain whether shorter feeding intervals have any effect on any of our secondary outcomes including the duration of hospital stay (MD ‒3.36, 95% CI ‒9.18 to 2.46; 2 studies, 207 participants; very low-certainty evidence) and the risk of NEC (typical risk ratio 1.07, 95% CI 0.54 to 2.11; 4 studies, 417 participants; low-certainty evidence). No study reported growth during hospital stay. AUTHORS' CONCLUSIONS The low-certainty evidence we found in this review suggests that there may be no clinically important differences between two- and three-hourly feeding intervals. There is insufficient information about potential feeding complications and in particular NEC. No studies have looked at the effect of other feeding intervals and there is no long-term data on neurodevelopment or growth.

Abstract
INTRODUCTION Critical aspects of time of feed initiation, advancement, and volume of feed increment in preterm neonates remain largely unanswered. METHODS Medline , Embase, CENTRAL and CINAHL were searched from inception until 25th September 2020. Network meta-analysis with the Bayesian approach was used. Randomized controlled trials (RCTs) evaluating preterm neonates ≤32 weeks were included. Feeding regimens were divided based on the following categories: initiation day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); advancement day: early (<72 h), moderately early (72 h-7 days), and late (>7 days); increment volume: small volume (SV) (<20 mL/kg/day), moderate volume (MoV) (20-< 30 mL/kg/day), and large volume (≥30 mL/kg/day); and full enteral feeding from the first day. Sixteen regimens were evaluated. Combined outcome of necrotizing enterocolitis (NEC) stage ≥ II or mortality before discharge was the primary outcome. RESULTS A total of 39 studies enrolled around 6,982 neonates. Early initiation (EI) with moderately early or late advancement using MoV increment enteral feeding regimens appeared to be most efficacious in decreasing the risk of NEC or mortality when compared to EI and early advancement with SV increment (risk ratio [95% credible interval]: 0.39 [0.12, 0.95]; 0.34 [0.10, 0.86]) (GRADE-very low). CONCLUSIONS Early initiated, moderately early, or late advanced with MoV increment feeding regimens might be most appropriate in decreasing the risk of NEC stage ≥II or mortality. In view of the certainty of evidence being very low, adequately powered RCTs evaluating these 2 strategies are warranted.

Abstract
(1) Background: Intestinal failure-associated liver disease (IFALD) in adults is characterized by steatosis with variable progression to fibrosis/cirrhosis. Reference standard liver biopsy is not feasible for all patients, but non-invasive serological and quantitative MRI markers for diagnosis/monitoring have not been previously validated. Here, we examine the potential of serum scores and feasibility of quantitative MRI used in non-IFALD liver diseases for the diagnosis of IFALD steatosis; (2) Methods: Clinical and biochemical parameters were used to calculate serum scores in patients on home parenteral nutrition (HPN) with/without IFALD steatosis. A sub-group underwent multiparameter quantitative MRI measurements of liver fat fraction, iron content, tissue T1, liver blood flow and small bowel motility; (3) Results: Compared to non-IFALD (n = 12), patients with IFALD steatosis (n = 8) demonstrated serum score elevations in Enhanced Liver Fibrosis (p = 0.032), Aspartate transaminase-to-Platelet Ratio Index (p < 0.001), Fibrosis-4 Index (p = 0.010), Forns Index (p = 0.001), Gamma-glutamyl transferase-to-Platelet Ratio Index (p = 0.002) and Fibrosis Index (p = 0.001). Quantitative MRI scanning was feasible in all 10 sub-group patients. Median liver fat fraction was higher in IFALD steatosis patients (10.9% vs 2.1%, p = 0.032); other parameter differences were non-significant; (4) Conclusion: Serum scores used for non-IFALD liver diseases may be useful in IFALD steatosis. Multiparameter MRI is feasible in patients on HPN.

[PMID: 32356227 DOI: 10.1007/s12072-020-10048-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2020] [Accepted: 04/16/2020] [Indexed: 12/12/2022]
Abstract
Premature infants and children with intestinal failure (IF) or short bowel syndrome are susceptible to intestinal failure-associated liver disease (IFALD, previously referred to as parenteral nutrition-associated liver disease, or PNALD). IFALD in children is characterized by progressive cholestasis and biliary fibrosis, and steatohepatitis in adults, and is seen in individuals dependent upon prolonged administration of PN. Many factors have been proposed as contributing to the pathogenesis of IFALD. In recent years, the focus has been on the potential synergistic roles of the intestinal microbiome, increased intestinal permeability, activation of hepatic innate immune pathways, and the use of intravenous soybean-oil-based intravenous lipid emulsions (SO-ILE). In vitro and in vivo studies have identified stigmasterol, a component of the plant sterols present in SO-ILE, as playing an important role. Although various strategies have been adopted to prevent or reverse IFALD, most suffer from a lack of strong evidence supported by well-designed, prospective clinical trials with clearly defined endpoints. Reduction in the amount of SO-ILEs or replacement with non-SO-ILEs has been shown to reverse IFALD although safety and long-term effectiveness have not been studied. Medical and surgical modalities to increase intestinal adaptation, advance enteral feedings, and prevent central line bloodstream infections are also important preventative strategies. There is a continued need to conduct high-quality, prospective trials with clearly define outcome measures to ascertain the potential benefits of these strategies.

Abstract
BACKGROUND Intestinal Failure-Associated Liver Disease is characterized by cholestasis and hepatic dysfunction due to parenteral nutrition (PN) therapy. We described key features of cholestatic infants receiving PN to assess overall outcomes in this population at our institution. METHODS This is a retrospective single center study of 163 neonates grouped into cholestatic (n = 63) and non-cholestatic (n = 100) as defined by peak conjugated bilirubin of ≥2.0 mg/dL or < 0.8 mg/dL, respectively. Univariate and multiple regression models were used to study associations between variables and outcomes of interest. RESULTS Lower Apgar scores (4 ± 3 vs. 6 ± 3, p-value = <0.005 at 1 min; 6 ± 2 vs. 7 ± 2, p < 0.005 at 5 min) and lower birth weight (adj β [SE] = 0.62 [0.27], p-value = 0.024) were risk factors for developing cholestasis. Cholestatic infants were more likely to have had gastrointestinal surgery (31 [49%] vs. 15 [15%], p-value <0.005), received PN for a longer duration (40 ± 39 days vs. 11 ± 7 days, p-value <0.005), and started enteral feeds later in life (86 ± 23 days vs. 79 ± 20 days, p-value <0.005) when compared to non-cholestatic infants. Weight percentiles in cholestatic infants were lower both at hospital discharge (14 ± 19 vs. 24 ± 22, p-value <0.005) and at 6 months of age (24 ± 28 vs. 36 ± 31, p-value = 0.05). CONCLUSIONS Cholestasis in the NICU is a multifactorial process, but it has a long lasting effect on prospective weight gain in infants who receive PN in the NICU. This finding highlights the importance of follow-up for adequate growth and the potential benefit from aggressive nutritional support.

Abstract
OBJECTIVE We examined the effect of two strategies to prevent necrotizing enterocolitis (NEC) in extremely low birth weight (ELBW) infants-adherence to a standardized feeding protocol and use of a hospital-based milk bank to provide exclusive preterm human milk feedings. STUDY DESIGN We conducted a single-center observational study from 2010 to 2015. Infants received preterm human milk, initially trophic feeds from days 7 to 14 after birth, followed by advancement of 15 mL/kg/day to reach a goal of 180 mL/kg/day. Fortification was used selectively for weight gain < 15 g/kg/day. We determined the incidence of NEC, other morbidities, and growth. RESULTS The cohort included 398 ELBW infants who survived to day 14 without congenital anomalies. Mean gestational age was 26.2 ± 1.9 weeks. Maternal milk was used as the sole feeding in 62% of infants; preterm donor milk was used solely or as supplement in 29%. Full feeds were reached at a median of 27 (IQR 23, 33) days. Four infants (1%) developed NEC. CONCLUSION Use of standardized feedings with a hospital-based milk bank is associated with an incidence of NEC lower than previously reported.

Gastric Residual Volumes Versus Abdominal Girth Measurement in Assessment of Feed Tolerance in Preterm Neonates: A Randomized Controlled Trial. Adv Neonatal Care 2018; 18:E13-E19.

Abstract
BACKGROUND Preterm neonates often have feed intolerance that needs to be differentiated from necrotizing enterocolitis. Gastric residual volumes (GRV) are used to assess feed tolerance but with little scientific basis. PURPOSE To compare prefeed aspiration for GRV and prefeed measurement of abdominal girth (AG) in the time taken to reach full feeds in preterm infants. METHODS This was a randomized controlled trial. Infants with a gestational age of 27 to 37 weeks and birth weight of 750 to 2000 g, who required gavage feeds for at least 48 hours, were included. Infants were randomized into 2 groups: infants in the AG group had only prefeed AG measured. Those in the GRV group had prefeed gastric aspiration obtained for the assessment of GRV. The primary outcome was time to reach full enteral feeds at 150 mL/kg/d, tolerated for at least 24 hours. Secondary outcomes were duration of hospital stay, need for parenteral nutrition, episodes of feed intolerance, number of feeds withheld, and sepsis. RESULTS Infants in the AG group reached full feeds earlier than infants in the GRV group (6 vs 9.5 days; P = .04). No significant differences were found between the 2 groups with regard to secondary outcomes. IMPLICATIONS FOR PRACTICE Our research suggests that measurement of AG without assessment of GRV enables preterm neonates to reach full feeds faster than checking for GRV. IMPLICATIONS FOR RESEARCH Abdominal girth measurement as a marker for feed tolerance needs to be studied in infants less than 750 g and less than 26 weeks of gestation.

Abstract
We recommend that intestinal failure associated liver disease (IFALD) should be diagnosed by the presence of abnormal liver function tests and/or evidence of radiological and/or histological liver abnormalities occurring in an individual with IF, in the absence of another primary parenchymal liver pathology (e.g. viral or autoimmune hepatitis), other hepatotoxic factors (e.g. alcohol/medication) or biliary obstruction. The presence or absence of sepsis should be noted, along with the duration of PN administration. Abnormal liver histology is not mandatory for a diagnosis of IFALD and the decision to perform a liver biopsy should be made on a case-by-case basis, but should be particularly considered in those with a persistent abnormal conjugated bilirubin in the absence of intra or extra-hepatic cholestasis on radiological imaging and/or persistent or worsening hyperbilirubinaemia despite resolution of any underlying sepsis and/or any clinical or radiological features of chronic liver disease. Nutritional approaches aimed at minimising PN overfeeding and optimising oral/enteral nutrition should be instituted to prevent and/or manage IFALD. We further recommend that the lipid administered is limited to less than 1 g/kg/day, and the prescribed omega-6/omega-3 PUFA ratio is reduced wherever possible. For patients with any evidence of progressive hepatic fibrosis or overt liver failure, combined intestinal and liver transplantation should be considered.

Abstract
Intestinal failure-associated liver disease (IFALD) is a threatening complication for children on long-term parenteral nutrition because of intestinal failure. When progressive and intractable, it may jeopardize intestinal rehabilitation and lead to combined liver and intestinal transplantation. The institution of dedicated intestinal failure centers has dramatically decreased the incidence of such complication. IFALD may rapidly fade away if very early management aimed at preventing progression to end-stage liver disease is provided. In this review, we address the etiology and risk factors of IFALD in order to introduce pillars of prevention (nutritional management and catheter-related infections control). The latest evidence of therapeutic strategies, such as medical and surgical treatments, is also discussed.

Abstract
Necrotizing enterocolitis (NEC) continues to afflict approximately 7% of preterm infants born weighing less than 1500g, though recent investigations have provided novel insights into the pathogenesis of this complex disease. The disease has been a major cause of morbidity and mortality in neonatal intensive care units worldwide for many years, and our current understanding reflects exceptional observations made decades ago. In this review, we will describe NEC from a historical context and summarize seminal findings that underscore the importance of enteral feeding, the gut microbiota, and intestinal inflammation in this complex pathophysiology.

Abstract
BACKGROUND Minimal enteral nutrition (MEN) may induce a diet-dependent stimulation of gut adaptation following intestinal resection. Bovine colostrum is rich in growth factors, and we hypothesized that MEN with colostrum would stimulate intestinal adaptation, compared with formula, and would be well tolerated in patients with short bowel syndrome. METHODS In experiment 1, 3-day-old piglets with 50% distal small intestinal resection were fed parenteral nutrition (PN, n = 10) or PN plus MEN given as either colostrum (PN-COL, n = 5) or formula (PN-FORM, n = 9) for 7 days. Intestinal nutrient absorption and histomorphometry were performed. In experiment 2, tolerance and feasibility of colostrum supplementation were tested in a pilot study on 5 infants who had undergone intestinal resection, and they were compared with 5 resected infants who served as controls. RESULTS In experiment 1, relative wet-weight absorption and intestinal villus height were higher in PN-COL vs PN (53% vs 23% and 362 ± 13 vs 329 ± 7 µm, P < .05). Crypt depth and tissue protein synthesis were higher in PN-COL (233 ± 7 µm, 22%/d) and PN-FORM (262 ± 13 µm, 22%/d) vs PN (190 ± 4 µm, 9%/d, both P < .05). In experiment 2, enteral colostrum supplementation was well tolerated, and no infants developed clinical signs of cow's milk allergy. CONCLUSION Minimal enteral nutrition feeding with bovine colostrum and formula induced similar intestinal adaptation after resection in piglets. Colostrum was well tolerated by newly resected infants, but the clinical indication for colostrum supplementation to infants subjected to intestinal resection remains to be determined.

Abstract
BACKGROUND & AIMS Chronic Intestinal Failure (CIF) is the long-lasting reduction of gut function, below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation is required to maintain health and/or growth. CIF is the rarest organ failure. Home parenteral nutrition (HPN) is the primary treatment for CIF. No guidelines (GLs) have been developed that address the global management of CIF. These GLs have been devised to generate comprehensive recommendations for safe and effective management of adult patients with CIF. METHODS The GLs were developed by the Home Artificial Nutrition & Chronic Intestinal Failure Special Interest Group of ESPEN. The GRADE system was used for assigning strength of evidence. Recommendations were discussed, submitted to Delphi rounds, and accepted in an online survey of ESPEN members. RESULTS The following topics were addressed: management of HPN; parenteral nutrition formulation; intestinal rehabilitation, medical therapies, and non-transplant surgery, for short bowel syndrome, chronic intestinal pseudo-obstruction, and radiation enteritis; intestinal transplantation; prevention/treatment of CVC-related infection, CVC-related occlusion/thrombosis; intestinal failure-associated liver disease, gallbladder sludge and stones, renal failure and metabolic bone disease. Literature search provided 623 full papers. Only 12% were controlled studies or meta-analyses. A total of 112 recommendations are given: grade of evidence, very low for 51%, low for 39%, moderate for 8%, and high for 2%; strength of recommendation: strong for 63%, weak for 37%. CONCLUSIONS CIF management requires complex technologies, multidisciplinary and multiprofessional activity, and expertise to care for both the underlying gastrointestinal disease and to provide HPN support. The rarity of the condition impairs the development of RCTs. As a consequence, most of the recommendations have a low or very low grade of evidence. However, two-thirds of the recommendations are considered strong. Specialized management and organization underpin these recommendations.

Abstract
BACKGROUND The aim of the study was to compare prefeed abdominal circumference (AC) and gastric residual volume (GRV) as a measure of feed intolerance in very-low-birth-weight infants (VLBW). METHODS Eighty VLBW infants were randomized to 2 groups; feed intolerance was monitored by measuring either GRV group or prefeed AC group. The primary outcome was time to full enteral feeds (180 mL · kg · day). Other main outcome measures were feed interruption days, duration of parenteral nutrition, incidence of culture positive sepsis, necrotizing enterocolitis, mortality, and duration of hospital stay. RESULTS The median (interquartile range) time to achieve full feeds was 10 (9-13) versus 14 (12-17.5) days in AC and GRV groups, respectively (P < 0.001). Infants in AC group had fewer feed interruption days (0 [0-2] vs 2.0 [1, 5], P < 0.001) and shorter duration of parenteral nutrition (P < 0.001). The incidence of culture-positive sepsis in AC and GRV groups was 17.5% and 30 %, respectively (P = 0.18). Duration of hospital stay and mortality were comparable in both the groups. CONCLUSIONS Prefeed AC as a measure of feed intolerance in VLBW infants may shorten the time taken to achieve full feeds.

Reducing necrotizing enterocolitis in very low birth weight infants using quality-improvement methods. J Perinatol 2014; 34:850-7. [PMID: 25010221 PMCID: PMC4216600 DOI: 10.1038/jp.2014.123] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2014] [Revised: 05/12/2014] [Accepted: 05/14/2014] [Indexed: 11/12/2022]
Abstract
OBJECTIVE Owing to a rise in necrotizing enterocolitis (NEC, stage ⩾ 2) among very low birth weight (VLBW, birth weight <1500 g) infants from 4% in 2005 to 2006 to 10% in 2007 to 2008, we developed and implemented quality improvement (QI) initiatives. The objective was to evaluate the impact of QI initiatives on NEC incidence in VLBW infants. STUDY DESIGN In September 2009, we developed an NEC QI multidisciplinary team that conducted literature reviews and reviewed practices from other institutions to develop a feeding protocol, which was implemented in December 2009. The team tracked intervention compliance and occurrence of NEC stage ⩾ 2. In May 2010, we reviewed our nasogastric tube practice and relevant literature to develop a second intervention that reduced nasogastric tube indwelling time. The infants were divided into three groups: baseline (January 2008 to Novovember 2009, n219), QI phase 1 (December 2009 to May 2010, n62) and QI phase 2 (June 2010 to November 2011, n170). RESULT The NEC incidence did not decrease after implementation of the feeding protocol in QI phase 1 (19.4%) but did decline significantly after changing nasogastric tube management in QI phase 2 (2.9%). Multivariable logistic regression analysis demonstrated a significant relationship between QI phase and the incidence of NEC. CONCLUSION QI initiatives were effective in decreasing NEC incidence in our high human milk-feeding NICU. Nasogastric tube bacterial contamination may have contributed to our peak in NEC incidence.

Abstract
We previously reported the beneficial effect of fish oil-based lipid emulsions (FOLEs) as monotherapy in the treatment of parenteral nutrition-associated liver disease (PNALD). In this report, we share our ongoing experience at Texas Children's Hospital, Houston, Texas in the use of FOLE in treatment of PNALD as presented at the 2013 Experimental Biology meeting. We describe the findings of a single center, prospective, observational study of infants <6 mo of age with PNALD who received parenteral FOLE as monotherapy. A total of 97 infants received FOLE under the compassionate-use protocol for the treatment of PNALD. Eighty-three (86%) survived with resolution of cholestasis and 14 (14%) died. The median conjugated bilirubin (CB) concentration at the initiation of FOLE therapy was 4.8 mg/dL (range 2.1-26). The median time to resolution of cholestasis was 40 d (range 3-158). Compared with infants with mild cholestasis (CB of 2.1-5 mg/dL at the initiation of FOLE), nonsurvivors were significantly more premature and took longer to resolve their cholestasis. Gestational age at birth correlated inversely with CB at the beginning of FOLE and peak CB. Infants with an initial CB >10 mg/dL had a higher mortality rate than infants with an initial CB <5 mg/dL (35% vs. 6%; P < 0.05). Our experience with the use of FOLE in PNALD continues to be encouraging. Prematurity continues to be a major determinant in mortality and severity of cholestasis. This calls for further controlled studies designed to optimize dose and timing of intervention in the use of FOLE in neonates.

Abstract
OBJECTIVE To describe feeding and gastrointestinal outcomes in growth-restricted infants <29 weeks' gestation and to determine the rate of feed advancement which they tolerate. DESIGN Analysis of prospectively collected data from a randomised feeding trial, the Abnormal Doppler Enteral Prescription Trial (ADEPT). SETTING 54 neonatal units in the UK and Ireland. PARTICIPANTS 404 preterm, growth-restricted infants with abnormal antenatal Doppler studies from ADEPT. 83 infants <29 weeks and 312 infants ≥ 29 weeks' gestation were included in this analysis. INTERVENTIONS In ADEPT, infants were randomised to start milk 'early' on day 2 after birth, or 'late' on day 6. Subsequent feed advancement followed a regimen, which should have achieved full feeds by day 16 in the early and day 20 in the late group. MAIN OUTCOME MEASURES Full feeds were achieved later in infants <29 weeks; median age 28 days {IQR 22-40} compared with 19 days {IQR 17-23} in infants ≥ 29 weeks (HR 0.35, 95% CI 0.3 to 0.5). The incidence of necrotising enterocolitis was also higher in this group; 32/83 (39%) compared to 32/312 (10%) in those ≥ 29 weeks (RR 3.7, 95% CI 2.4 to 5.7). Infants <29 weeks tolerated very little milk for the first 10 days of life and reached full feeds 9 days later than predicted from the trial regimen. CONCLUSIONS Growth-restricted infants born <29 weeks' gestation with abnormal antenatal Doppler failed to tolerate even the careful feeding regimen of ADEPT. A slower advancement of feeds may be required for these infants. TRIAL REGISTRATION NUMBER ISRCTN87351483.

Abstract
PURPOSE Intestinal perforations are common in premature infants, leading to a diagnostic dilemma between necrotizing enterocolitis and isolated intestinal perforation (IIP). IIP is thought to result from a congenital or acquired absence of the muscularis propria. However, developmental events leading to IIP are not well understood. This study examines the relationship between corrected gestational age (CGA) and intestinal muscle development in controls and patients with IIP. METHODS Specimens from stillbirths and infants undergoing intestinal surgery from 8 to 48weeks' CGA were collected from 2005 to 2012. Twelve patients with IIP were identified. Control specimens were collected during 25 fetal autopsies and 39 bowel resections. In each case, three sections of intestine were examined histologically for muscularis mucosa, circular and longitudinal muscle thickness. Comparisons of control and perforated specimens were performed via linear regression and ANOVA. RESULTS Controls and adjacent normal segments in IIP showed a linear relationship between thickness of circular and longitudinal muscles with CGA. Circular and longitudinal muscles were thinner in perforated segments than in adjacent normals and CGA-matched controls (p<0.05). CONCLUSION Intestinal muscularis propria increases in thickness with CGA. Muscle thickness is focally attenuated in patients with isolated intestinal perforations, while the remaining intestine is normal, suggesting that primary repair is an appropriate treatment.

Abstract
Feeding intolerance (FI), defined as the inability to digest enteral feedings associated to increased gastric residuals, abdominal distension and/or emesis, is frequently encountered in the very preterm infant and often leads to a disruption of the feeding plan. In most cases FI represents a benign condition related to the immaturity of gastrointestinal function, however its presentation may largely overlap with that of an impending necrotizing enterocolitis. As a consequence, individual interpretation of signs of FI represents one of the most uncontrollable variables in the early nutritional management of these infants, and may lead to suboptimal nutrition, delayed attainment of full enteral feeding and prolonged intravenous nutrition supply. Strategies aimed at preventing and/or treating FI are diverse, although very few have been validated in large RCT and systematic reviews. The purpose of this paper is to summarize the existing information on this topic, spanning from patho-physiological and clinical aspects to the prevention and treatment strategies tested in clinical studies, with specific attention to practical issues.

Abstract
Preterm infants are often considered too unstable to be fed enterally so they are exposed to complications related to a prolonged enteral fasting. Our study aims to compare feeding tolerance of adequate for gestational age (AGA) versus small for gestational age (SGA) infants and to evaluate which perinatal factors affect feeding tolerance (measured as time to achieve full enteral feeding, FEF). Inborn infants with a gestational age (GA) less than 32 weeks, born from January 2006 to December 2010, were eligible for this study. We enrolled 310 infants. The time to FEF was longer for SGA infants than for AGA, while a longer GA was associated to a reduced time to FEF. A beneficial effect was observed for antenatal steroids, while Apgar score below 7, the administration of inotrops or caffeine, the occurrence of sepsis or NEC and the presence of PDA were associated to a longer time to FEF. When evaluated jointly with a multivariate analysis, GA (p < 0.0001), antenatal steroids prophylaxis (p = 0.002), SGA (p < 0.0001) and occurrence of NEC (p = 0.0002) proved to have independent prognostic impact on the time to FEF. Feeding tolerance is better as GA increases, and worsen in SGA infants. Antenatal betamethasone is effective in reducing the time to FEF in both AGA and SGA.

Abstract
BACKGROUND Cholestasis is a significant life-threatening complication in children on parenteral nutrition (PN). Strategies to prevent/treat PN-associated cholestasis (PNAC) and intestinal failure-associated liver disease (IFALD) have reached moderate success with little supporting evidence. Aims of this systematic review were (1) to determine the incidence of PNAC/IFALD in children receiving PN for ≥ 14 days and (2) to review the efficacy of measures to prevent/treat PNAC/IFALD. METHODS Of 4696 abstracts screened, 406 relevant articles were reviewed, and studies on children with PN ≥ 14 days and cholestasis (conjugated bilirubin ≥ 2 mg/dL) were included. Analyzed parameters were (1) PNAC/IFALD incidence by decade and by PN length and (2) PNAC/IFALD prevention and treatment (prospective studies). RESULTS Twenty-three articles (3280 patients) showed an incidence of 28.2% and 49.8% of PNAC and IFALD, respectively, with no evident alteration over the last decades. The incidence of PNAC was directly proportional to the length of PN (from 15.7% for PN ≤ 1 month up to 60.9% for PN ≥ 2 months; P < .0001). Ten studies on PNAC met inclusion criteria. High or intermediate-dose of oral erythromycin and aminoacid-free PN with enteral whey protein gained significant benefits in preterm neonates (P < .05, P = .003, and P < .001, respectively). None of the studies reviewed met inclusion criteria for treatment. CONCLUSIONS The incidence of PNAC/IFALD in children has no obvious decrease over time. PNAC is directly correlated to the length of PN. Erythromycin and aminoacid-free PN with enteral whey protein have shown to prevent PNAC in preterm neonates. There is a lack of high-quality prospective studies, especially on IFALD.

Abstract
BACKGROUND The introduction of enteral feeds for very preterm (< 32 weeks) or very low birth weight (< 1500 grams) infants is often delayed due to concern that early introduction may not be tolerated and may increase the risk of necrotising enterocolitis. However, prolonged enteral fasting may diminish the functional adaptation of the immature gastrointestinal tract and extend the need for parenteral nutrition with its attendant infectious and metabolic risks. Trophic feeding, giving infants very small volumes of milk to promote intestinal maturation, may enhance feeding tolerance and decrease the time taken to reach full enteral feeding independently of parenteral nutrition. OBJECTIVES To determine the effect of early trophic feeding versus enteral fasting on feed tolerance, growth and development, and the incidence of neonatal morbidity (including necrotising enterocolitis and invasive infection) and mortality in very preterm or VLBW infants. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group. This included electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12), MEDLINE, EMBASE and CINAHL (1980 until December 2012), conference proceedings and previous reviews. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that assessed the effects of early trophic feeding (milk volumes up to 24 ml/kg/day introduced before 96 hours postnatal age and continued until at least one week after birth) versus a comparable period of enteral fasting in very preterm or very low birth weight infants. DATA COLLECTION AND ANALYSIS We extracted data using the standard methods of the Cochrane Neonatal Review Group with separate evaluation of trial quality and data extraction by two authors and synthesis of data using risk ratio, risk difference and mean difference. MAIN RESULTS Nine trials in which a total of 754 very preterm or very low birth weight infants participated were eligible for inclusion. Few participants were extremely preterm (< 28 weeks) or extremely low birth weight (< 1000 grams) or growth restricted. These trials did not provide any evidence that early trophic feeding affected feed tolerance or growth rates. Meta-analysis did not detect a statistically significant effect on the incidence of necrotising enterocolitis: typical risk ratio 1.07 (95% confidence interval 0.67 to 1.70); risk difference 0.01 (-0.03 to 0.05). AUTHORS' CONCLUSIONS The available trial data do not provide evidence of important beneficial or harmful effects of early trophic feeding for very preterm or very low birth weight infants. The applicability of these findings to extremely preterm, extremely low birth weight or growth restricted infants is limited. Further randomised controlled trials would be needed to determine how trophic feeding compared with enteral fasting affects important outcomes in this population.

Abstract
OBJECTIVE The aim of this study was to review evidence-based data addressing key clinical questions regarding parenteral nutrition-associated cholestasis (PNAC) and parenteral nutrition-associated liver disease (PNALD) in children. DATA SOURCE Data were obtained from PubMed, Medicine databases of the English literature (up to October 2010), and the Cochrane Database of Systematic Reviews. STUDY SELECTION The review of PNAC/PNALD has been divided into 4 areas to simplify one's understanding of the current knowledge regarding the pathogenesis and treatment of this disease: (1) nonnutrient risk factors associated with PNAC, (2) PNAC and lipid emulsions, (3) nutritional (nonlipid) considerations in the prevention of PNAC, and (4) supplemental medications in the prevention and treatment of PNAC. RESULTS The data for each topic area relevant to the clinical practice of pediatric surgery were reviewed, evaluated, graded, and summarized. CONCLUSIONS Although the conditions of PNAC and PNALD have been well recognized for more than 30 years, only a few concrete associations and treatment protocols have been established.

Abstract
AIM To evaluate whether preterm neonates weighing 1000-1499 g at birth receiving rapid enteral feeding advancement at 30 mL/kg/day attain full feedings (180 mL/kg/day) earlier than those receiving slow enteral feeding advancement at 20 mL/kg/day without increase in the incidence of feeding intolerance or necrotizing enterocolitis. METHODS A total of 100 stable intramural neonates weighing between 1000 and 1499 g and gestational age less than 34 weeks were randomly allocated to enteral feeding (expressed human milk or formula) advancement of 20 mL/kg/day (n = 50) or 30 mL/kg/day (n = 50). RESULTS Neonates in the rapid feeding advancement group achieved full volume feedings before the slow advancement group (median 7 days vs. 9 days) (p < 0.001), had significantly fewer days of intravenous fluids (median 2 days vs. 3.4 days) (p < 0.001), shorter length of stay in hospital (median 9.5 days vs. 11 days) (p = 0.003) and regained birth weight earlier (median 16 days vs. 22 days) (p < 0.001). There were no statistical differences in the proportion of infants with apnea, feed interruption or feed intolerance. CONCLUSION Rapid enteral feeding advancements of 30 mL/kg/day are well tolerated by stable preterm neonates weighing 1000-1499 g.

Abstract
BACKGROUND Pregnancies complicated by abnormal umbilical artery Doppler blood flow patterns often result in the baby being born both preterm and growth-restricted. These babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure, and there is no clinical consensus about how best to feed them. Policies of both early milk feeding and late milk feeding are widely used. This randomised controlled trial aims to determine whether a policy of early initiation of milk feeds is beneficial compared with late initiation. Optimising neonatal feeding for this group of babies may have long-term health implications and if either of these policies is shown to be beneficial it can be immediately adopted into clinical practice. METHODS AND DESIGN Babies with gestational age below 35 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen, commencing milk feeds on day 2 and day 6 after birth, respectively. Feeds will be gradually increased over 9-13 days (depending on gestational age) using a schedule derived from those used in hospitals in the Eastern and South Western Regions of England, based on surveys of feeding practice. Primary outcome measures are time to establish full enteral feeding and necrotising enterocolitis; secondary outcomes include sepsis and growth. The target sample size is 400 babies. This sample size is large enough to detect a clinically meaningful difference of 3 days in time to establish full enteral feeds between the two feeding policies, with 90% power and a 5% 2-sided significance level. Initial recruitment period was 24 months, subsequently extended to 38 months. DISCUSSION There is limited evidence from randomised controlled trials on which to base decisions regarding feeding policy in high risk preterm infants. This multicentre trial will help to guide clinical practice and may also provide pointers for future research. TRIAL REGISTRATION Current Controlled Trials ISRCTN: 87351483.

Abstract
OBJETIVO: Analisar as práticas precoces de alimentação e o tipo de dieta de prematuros na alta hospitalar. MÉTODOS: Estudo descritivo, a partir de uma coorte retrospectiva de dois anos, com 203 prematuros com peso menor que 1 500g, na maternidade do Hospital Geral de Bonsucesso, Rio de Janeiro. Foram avaliadas as seguintes práticas: dias para início de dieta enteral, dias para atingir a dieta enteral plena, dias para início e tempo de uso de nutrição parenteral e o tipo de dieta na alta hospitalar. RESULTADOS: O tempo médio para início de dieta enteral foi de 6,5 dias (IC95% 6,0-7,2), enquanto para atingir a dieta enteral plena levou-se, em média, 18,9 dias (IC95% 17,6-20,3). A média de dias para início de nutrição parenteral foi de 2,8 dias (IC95% 2,6-3,0) e o tempo de uso de nutrição parenteral foi de 10,8 dias (IC95% 9,7-11,9). As práticas se associaram, sendo encontrada a maior correlação entre dias para atingir dieta plena e dias de uso de nutrição parenteral (Pearson=0,69). Quanto menor o peso de nascimento, maior o tempo para início de dieta enteral, para atingir a dieta enteral plena e de uso de nutrição parenteral. Para o início de nutrição parenteral, não foi observada esta tendência. Na alta, o tipo de dieta mais freqüente foi o aleitamento complementado (61,6%), seguido da alimentação artificial (26,1%) e do aleitamento materno exclusivo (12,3%). CONCLUSÃO: Este estudo revelou que há demora em iniciar a alimentação de prematuros. A proporção total de aleitamento na alta foi de 74%. Esforços merecem ser envidados para alimentar precocemente e promover o aleitamento materno nestes pacientes.

Abstract
BACKGROUND The introduction of enteral feeds for very low birth weight (VLBW) infants is often delayed due to concern that early introduction may not be tolerated and may increase the risk of necrotising enterocolitis. However, enteral fasting may diminish the functional adaptation of the immature gastrointestinal tract and prolong the need for parenteral nutrition with its attendant infectious and metabolic risks. Early trophic feeding, giving infants very small volumes of milk during the first week after birth, may promote intestinal maturation, enhance feeding tolerance and decrease time to reach full enteral feeding independently of parenteral nutrition. OBJECTIVES To determine the effect of early trophic feeding versus enteral fasting on feed tolerance, growth, and the incidence of necrotising enterocolitis, mortality and other morbidities in VLBW infants. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Group was used. Searches were made of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2009), MEDLINE (1966 - February 2009), EMBASE (1980 - February 2009), CINAHL (1982 - February 2009), conference proceedings, and previous reviews. SELECTION CRITERIA Randomised or quasi-randomised controlled trials that assessed the effects of early trophic feeding (milk volumes up to 24 ml/kg/day introduced before 96 hours postnatal age and continued until at least one week after birth) versus a comparable period of enteral fasting in VLBW infants. DATA COLLECTION AND ANALYSIS The standard methods of the Cochrane Neonatal Group were used, with separate evaluation of trial quality and data extraction by two review authors. Data were synthesised using a fixed effects model and reported using typical relative risk, typical risk difference and weighted mean difference. MAIN RESULTS Nine trials, in which a total of 754 VLBW infants participated, were eligible for inclusion. These trials did not provide any evidence that early trophic feeding affected feed tolerance or growth rates in VLBW infants. Meta-analysis did not detect a statistically significant effect on the incidence of necrotising enterocolitis: typical relative risk 1.07 (95% confidence interval 0.67, 1.70); typical risk difference 0.01 (95% confidence interval -0.04, 0.05). AUTHORS' CONCLUSIONS The available data cannot exclude important beneficial or harmful effects and are insufficient to inform clinical practice. Further large pragmatic randomised controlled trials are needed to determine how early trophic feeding compared with enteral fasting affects important clinical outcomes in VLBW infants.

Abstract
Nutrition plays a major role in the modulation of the evolving human gut influencing all the main components of the intestinal ecosystem. The regulatory role of nutrition is particularly crucial in the early postnatal period but it continues also in subsequent ages when the development of the gastrointestinal tract is completed. Recent data support the hypothesis that nutrition can affect some inherited disorders of gastrointestinal tract. These "epigenetic" mechanisms are involved in the development of intestinal enzymes, hormones, transporters, and immunity. This is an expanding research area related to the possible nutritional intervention in selected clinical condition. This paper is focused on the main components and mechanisms of action of the nutritional modulation on intestinal development.

Abstract
OBJECTIVE To gather information regarding the efficacy of early minimal enteral nutrition on overall feeding tolerance in extremely low birth weight infants. STUDY DESIGN Prospective randomized controlled trial comparing the early use of minimal enteral nutrition in extremely low birth weight infants from day 2 to day 7 vs control infants. On day 8, feeding volume in both groups were advanced by 10 ml kg(-1) day(-1) until full enteral feedings were reached. Time to full feeds, number of intolerance episodes, anthropometric measurements, peak total bilirubin levels, incidence of necrotizing enterocolitis and incidence of sepsis were compared between the two groups with t-test and chi (2) test. RESULT Eighty-four infants were enrolled in the study but only 61 infants completed the feeding protocol. No statistically significant differences were found between the groups with regards to growth patterns, feeding tolerance, mortality, length of hospital stay and incidence of sepsis and necrotizing enterocolitis. CONCLUSION Early minimal enteral nutrition use in extremely low birth weight infants did not improve feeding tolerance.

Abstract
Although parenteral nutrition has been used widely in the management of sick very low birth weight infants, a smooth transition to the enteral route is most desirable. Trophic feeding is the practice of feeding small volume of enteral feeds in order to stimulate the development of the immature gastrointestinal tract of the preterm infant. This practice has also been termed as minimal enteral nutrition (MEN). MEN improves gastrointestinal enzyme activity, hormone release, blood flow, motility and microbial flora. Clinical benefits include improved milk tolerance, greater postnatal growth, reduced systemic sepsis and shorter hospital stay. There is currently no evidence of any adverse effects following MEN. MEN can be commenced in neonates on ventilation and total parenteral nutrition. A protocol of giving MEN has been presented here.

Abstract
The incidence of preterm births has continued to increase over the past 25 years, and therefore the optimal feeding of these infants is an important clinical concern. This review focuses on intestinal development and physiology, with a particular emphasis on developmentally immature functions of the preterm intestine and the resulting implications for nutrition therapies used to feed the preterm infant.

Abstract
In initiating enteral feedings for high-risk infants, clinicians struggle with three fundamental questions: When should enteral feedings be initiated? Should a period of trophic (minimal) feeding be provided? When feedings are advanced, how rapidly should the volume be increased? We present the findings of our systematic reviews of randomized trials addressing each of these questions. These reviews identified various limited short-term benefits of initiating feedings early, providing a period of trophic feedings, and increasing the volume at a relatively rapid rate when feedings are advanced. However, the safety and effectiveness of these approaches are unclear due to limitations in trial design, an inadequate sample size, and the problems inherent in evaluating the effects of initial feeding regimen on necrotizing enterocolitis (NEC) and neurodevelopmental outcome. We provide a detailed description of how a multicenter clinical trial might best be designed to adequately address these questions. In our view, it would be necessary to assess the effect of three feeding regimens on survival without neurodevelopmental impairment (primary outcome) among extremely low birth weight (ELBW) infants. The most daunting obstacle to resolving our current feeding dilemmas is the sample size required to assess all important outcomes. Even in the largest existing research network that achieves a high follow-up rate (the NICHD Neonatal Research Network), it is not feasible to meet conventional (frequentist) sample size requirements. Fortunately, this problem may be addressed using Bayesian methods. (For this reason and because Bayesian methods are likely to be increasingly used in neonatal trials, we provide a brief introduction to these methods.) We show that, with the sample size achievable in the Neonatal Network, Bayesian analyses are likely to provide clear and clinically useful assessments of the probability of benefit for all important clinical outcomes resulting from initial feeding regimens for ELBW infants.

Abstract
Neonatal necrotizing enterocolitis is the second most common cause of morbidity in premature infants and requires intensive care over an extended period. Despite advances in medical and surgical techniques, the mortality and long-term morbidity due to necrotizing enterocolitis remain very high. Recent advances have shifted the attention of researchers from the classic triad (ischemia, bacteria, and the introduction of a metabolic substrate into the intestine) of necrotizing enterocolitis, to gut maturation, feeding practices, and inflammation. The focus on inflammation includes proinflammatory cytokines such as tumor necrosis factor-alpha, interleukin (IL)-6, IL-18, and platelet-activating factor. Research related to the etiology of necrotizing enterocolitis has moved quickly from clostridial toxin to bacterial and other infectious agents. More recently, the pattern of bacterial colonization has been given emphasis rather than the particular species or strain of bacteria or their virulence. Gram-negative bacteria that form part of the normal flora are now speculated as important factors in triggering the injury process in a setting where there is a severe paucity of bacterial species and possible lack of protective Gram-positive organisms. Although the incidence of necrotizing enterocolitis has increased because of the survival of low birthweight infants, clinicians are more vigilant in their detection of the early gastrointestinal symptoms of necrotizing enterocolitis; however, radiographic demonstration of pneumatosis intestinalis remains the hallmark of necrotizing enterocolitis. With prompt diagnosis, a large proportion of infants with necrotizing enterocolitis are now able to be managed medically with intravenous fluid and nutrition, nasogastric suction, antibacterials, and close monitoring of physiologic parameters. In the advanced cases that require surgery, clinicians tend to opt for either simple peritoneal drainage (for very small and sick infants) or laparotomy and resection of the affected part. Intestinal transplantation later in life is available as a viable option for those who undergo resection of large segments of the intestine. It is becoming more evident that treatment of this devastating disease is expensive and comes with the toll of significant long-term sequelae. This has resulted in renewed interest in designing alternative strategies to prevent this serious gastrointestinal disease. Simple trophic feeding and the use of L-glutamine and arginine are novel avenues that have been examined. The use of probiotics ('friendly' bacterial flora) has been introduced as a promising tool for establishing healthy bacterial flora in the newborn gut to block the injury process that may ultimately lead to necrotizing enterocolitis.

Abstract
Preterm intrauterine growth restriction (IUGR) is strongly associated with increased mortality and morbidity. In the management of these infants, complications of preterm birth can be amplified by the effect of suboptimal fetal growth. It is important that pregnancies with IUGR are detected before birth, so that delivery can be arranged in a high-risk maternity unit with the appropriate neonatal staff in attendance. The provision of full support for resuscitation and stabilisation of these infants is crucial to the short-term and long-term health of these infants, who have suffered chronic hypoxia and malnutrition in utero. The long term outcome studies of these infants are retrospective and they include SGA infants. The effects of prematurity affect the outcome of IUGR infants. IUGR is associated with cerebral palsy in those delivered more than 32 weeks gestation. Infants less than 32 weeks of gestation may have poor developmental outcome if the head growth is affected, these infants may have associated cognitive and behavioural problems. Children who fail to grow by 2-4 years are at risk of long term growth problems. This paper outlines the acute and long-term management of these infants.

Abstract
Providing optimal nutrition for the very low birth weight (VLBW) infant is critical during the neonatal period. Evidence-based practice guidelines are essential in managing these fragile infants. Putting scientific research into daily clinical practice may be arduous at times, however. A multidisciplinary team of health care providers successfully established a practical feeding guideline for a 52-bed, teaching-affiliated, Level III neonatal intensive care unit in St. Louis. This guideline identifies human milk as the recommended source of nutrition for the VLBW infant, a suggestion that has significantly affected lactation services in the unit. This article describes the process of developing, implementing, and evaluating a feeding guideline based on current research and describes the impact on lactation rates of having such a guideline in place within the unit.

Abstract
BACKGROUND Because of concern that feedings may increase the risk of necrotizing enterocolitis, some high-risk infants have received prolonged periods of parenteral nutrition without enteral feedings. Providing trophic feedings (small volume feedings given at the same rate for at least 5 days) during this period of parenteral nutrition was developed as a strategy to enhance feeding tolerance and decrease time to reach full feedings. Whether trophic feedings result in better outcomes than initially withholding feedings or providing progressively increasing feedings can be established only in proper clinical trials. OBJECTIVES 1. For high-risk neonates receiving parenteral feedings, to assess the effect of trophic feeding compared to no enteral nutrient intake on measures of feeding tolerance and neonatal outcome.2. For high-risk neonates receiving parenteral feedings to assess the effect of trophic feedings compared to a specific initial feeding regimen involving a greater enteral nutrient intake on measures of feeding tolerance and neonatal outcome. SEARCH STRATEGY Searches were performed of MEDLINE (1966 - June 2004), CINAHL (1982 - June 2004), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2004), abstracts and conference proceedings, references from relevant publications in the English language, and studies identified by personal communication. SELECTION CRITERIA Only randomized or quasi-randomized clinical trials were considered. Trials were included if they enrolled high-risk infants randomly assigned to receive trophic feedings (defined as dilute or full strength feedings providing < = 25 kcal/kg/d for > = 5d) compared to either 1) no enteral nutrient intake (no feedings or water only) or 2) a specific feeding regimen involving a greater enteral intake of formula or human milk than with trophic feedings. DATA COLLECTION AND ANALYSIS The two reviewers reached consensus for inclusion of trials. Data regarding clinical outcomes were extracted and evaluated by the two reviewers independently of each other. Authors were contacted as needed and feasible to clarify or provide missing data. The specific data that were needed were requested in writing. MAIN RESULTS 1. Trophic feedings vs. no feedings (10 trials): Among infants given trophic feedings, there was an overall reduction in days to full feeding (weighted mean difference [WMD] = -2.6 [95% confidence limits = -4.1, -1.0]), total days that feedings were held (WMD = -3.1 [-4.6, -1.6]), and total hospital stay (WMD = -11.4 [-17.2, -5.7] compared to infants given no enteral nutrient intake. Tests for heterogeneity were significant in analyses of days to full enteral feedings, days to regain birth weight, days of phototherapy, and hospital stay. There was no significant difference in necrotizing enterocolitis, although the findings do not exclude an important effect (relative risk = 1.16 [0.75, 1.79]; risk difference = 0.02 [-0.03, 0.06].2. Trophic feedings vs. advancing feedings (one trial): Infants given trophic feedings required more days to reach full enteral feeding (13.4 [8.2, 18.6]) and tended to have a longer hospital stay (11.0 [-1.4, 23.4]) than did infants given advancing feedings. With only eight total cases of necrotizing enterocolitis, trophic feedings were associated with a marginally significant reduction in necrotizing enterocolitis (relative risk =0.14 [0.02, 1.07]; risk difference = -0.09 [-0.16, -0.01]. AUTHORS' CONCLUSIONS In both comparisons, the group with the greater enteral intake (trophic feedings in the first comparison and advancing feedings in the second comparison) required significantly less time to reach full feedings and had a significant or near significant reduction in hospital stay. In both comparisons, the group with the greater intake also had a higher incidence of necrotizing enterocolitis although the difference was not statistically significant. The concern is greatest for the advancing feeding regimen. Even when trophic feedings were compared to no feedings, the relative risk for necrotizing enterocolitis was 1.16 (0.75 - 1.79), a finding consistent with a 16% increase in necrotizing enterocolitis and a number needed to harm of 50. A true increase of this magnitude might outweigh any short- or long-term benefits of trophic feedings. Moreover, the 95% confidence interval does not exclude the possibility that trophic feedings increase necrotizing enterocolitis by as much as 79% with a number needed to harm of 17. Whether no feedings, trophic feedings, or advancing feedings should initially be used is difficult to discern for a variety of reasons--the inherent difficulty of assessing enteral feedings in high-risk infants, the limited sample size and methodologic limitations of most studies to date, unexplained heterogeneity with respect to a number of outcomes, the potential for bias to affect the findings in unblinded studies, and the large number of infants who must be studied to assess the effect on necrotizing enterocolitis. One or more large, well designed, multi-center trials are needed to compare these approaches to early feeding with respect to important clinical outcomes. A conclusive evaluation would assess effects on not only the survival rate without necrotizing enterocolitis prior to discharge from the neonatal unit but also on the survival rate without severe gastrointestinal or neurodevelopmental disability at >= 18 months age.

Abstract
The diagnosis of neonatal necrotizing enterocolitis is one of great concern to pediatric and neonatal clinicians. Intravenous access remains an integral part of the medical and surgical management of infants with this diagnosis, and the infusion nurse is intimately involved in the care of these patients. This article discusses the definition of necrotizing enterocolitis, presents current knowledge regarding its basic pathophysiology, and identifies common and rare sequelae of this oftentimes devastating disease of premature infants. Medical and surgical management goals of therapy are described. This overview will aid the infusion nurse in caring for these patients.

Abstract
OBJECTIVES The authors hypothesized that acute respiratory distress (ARD) delays gastric emptying. The objective was to test this hypothesis by assessing gastric emptying on the second and seventh days of life in premature infants with ARD resulting from pulmonary disease. METHODS Thirty-nine newborns with ARD starting on the first day of life were selected and paired with 39 healthy control newborns matched by weight (within 250 g). Gestational age was <or =35 weeks and birth weight was < or =1750 g for all subjects. Gastric emptying was assessed at 48.0 +/- 24.0 hours and at 168.0 +/- 24.0 hours of life. A test meal consisting of 3 mL/kg of 5% glucose in water labeled with phenol red was administered by gastric tube over 1 minute and gastric retention was determined as percent test meal remaining in the stomach 30 minutes after administration. RESULTS Gastric retention at 30 minutes varied considerably in both groups and was significantly higher (P < 0.01) in newborns with ARD (61.4%) than controls (51.8%) at 48.0 +/- 24.0 hours, decreasing significantly after partial or full remission of ARD at 168 +/- 24 hours of life. Gastric retention was 60.2% in newborns with feeding intolerance and 36.8% in tolerant newborns (P < 0.001) at 168 hours. ARD and periventricular or intraventricular hemorrhage were predictors of gastric retention at 48 +/- 24 hours of life, whereas feeding intolerance and gestational age were predictors of gastric retention at 168 +/- 24 hours. Gastric retention was inversely correlated with gestational age. CONCLUSION Gastric emptying is delayed in premature infants with ARD during the first 72 hours of life and may impair the initiation of enteral feeding.
