Abstract
BACKGROUND Preterm infants are fed by orogastric / nasogastric tube until they reach maturation and coordination of sucking, swallowing and respiration at approximately 32-34 weeks of corrected age. While being on non-invasive ventilation (NIV), they frequently present abdominal distension. Currently at our institution two techniques are used for the management of abdominal distension in preterm infants fed by bolus via orogastric tube: cenit and 2 x 1.The aim of this study was to compare the proportion of preterm infants presenting NIV-associated abdominal distension with each of these techniques. STUDY DESIGN We conducted a randomized clinical trial including infants of < 36.6 weeks of gestation and < 1500 g of birth weight who were admitted to our NICU during the period of April 1, 2016 to April 1, 2018 and received NIV. The presence of abdominal distension > 2 cm was the primary outcome. Secondary outcomes were presence of reflux, regurgitation, oxygen saturation during feeding and days to reach full feedings. Feeding tube drainage, stool characteristics and the use of prokinetics were confounding variables. RESULTS A total of 97 patients were included. Forty-six in the cenit group and 51 in the 2 x 1 group. There was no difference in the proportion of infants with abdominal distension > 2 cm between groups. Oxygen saturation during feeding at volume of 150 ml/kg/day was higher in the cenit group with statistical significance. CONCLUSION The use of cenit or 2 x 1 technique in preterm infants with NIV did not improve abdominal distension or other indicators of feeding tolerance.

Abstract
Necrotizing enterocolitis (NEC) is an acquired severe disease of the digestive system affecting mostly premature babies, possibly fatal and frequently associated to systemic complications. Because of the severity of this condition and the possible long-term consequences on the child's development, many studies have aimed at preventing the occurrence of the primary events at the level of the bowel wall (ischemia and necrosis followed by sepsis) by modifying or manipulating the diet (breast milk versus formula) and/or the feeding pattern (time for initiation after birth, continuous versus bolus feeding, modulation of intake according clinical events). Feeding have been investigated so far in order to prevent NEC. However, currently well-established and shared clinical nutritional practices are not available in preventing NEC. Nutritional and surgical treatments of NEC are instead well defined. In selected cases surgery is a therapeutic option of NEC, requiring sometimes partial intestinal resection responsible for short bowel syndrome. In this paper we will investigate the available options for treating NEC according to the Walsh and Kliegman classification, focusing on feeding practices in managing short bowel syndrome that can complicate NEC. We will also analyze the proposed ways of preventing NEC.

Abstract
BACKGROUND Fear of necrotizing enterocolitis (NEC) has perpetuated delayed initiation and slow advancement of enteral feeding in very low birth weight (VLBW) infants with inherent risks of parenteral alimentation. The objective of this study was to assess effect of early total enteral feeding (ETEF) on day of achievement of full enteral feeds, feed intolerance, NEC and sepsis. METHODS In total, 208 stable VLBW neonates (28-34 weeks) admitted during 6 month periods of three consecutive years were enrolled. First phase (n = 73) constituted the 'before' phase with standard practice of initial intravenous fluid therapy and slow enteral feeding. The second prospective phase (n = 51) consisted of implementation of ETEF with infants receiving full enteral feeds as per day's fluid requirement since Day 1 of life. The third phase (n = 84) was chosen to assess the sustainability of change in practice. RESULTS Day of achievement of full feeds was significantly earlier in Phases 2 and 3 compared with Phase 1 (8.97 and 5.47 vs. 14.44 days, respectively, p = 0.0001). Incidence of feed intolerance was comparable between Phases 1 and 2 (22 vs. 14%, p = 0.28), with marked reduction in incidence of NEC (14 vs. 4%, p = 0.028). There was a significant decrease in sepsis, duration of parenteral fluid and antibiotic therapy as well as hospital stay with comparable mortality. CONCLUSION In stable preterm VLBW infants, ETEF is safe and has the benefit of optimizing nutrition with decrease in sepsis, NEC and hospital stay.

Abstract
BACKGROUND Neonatal hyperbilirubinaemia is a common problem which carries a risk of neurotoxicity. Certain infants who have hyperbilirubinaemia develop bilirubin encephalopathy and kernicterus which may lead to long-term disability. Phototherapy is currently the mainstay of treatment for neonatal hyperbilirubinaemia. Among the adjunctive measures to compliment the effects of phototherapy, fluid supplementation has been proposed to reduce serum bilirubin levels. The mechanism of action proposed includes direct dilutional effects of intravenous (IV) fluids, or enhancement of peristalsis to reduce enterohepatic circulation by oral fluid supplementation. OBJECTIVES To assess the risks and benefits of fluid supplementation compared to standard fluid management in term and preterm newborn infants with unconjugated hyperbilirubinaemia who require phototherapy. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5), MEDLINE via PubMed (1966 to 7 June 2017), Embase (1980 to 7 June 2017), and CINAHL (1982 to 7 June 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA We included randomised controlled trials that compared fluid supplementation against no fluid supplementation, or one form of fluid supplementation against another. DATA COLLECTION AND ANALYSIS We extracted data using the standard methods of the Cochrane Neonatal Review Group using the Covidence platform. Two review authors independently assessed the eligibility and risk of bias of the retrieved records. We expressed our results using mean difference (MD), risk difference (RD), and risk ratio (RR) with 95% confidence intervals (CIs). MAIN RESULTS Out of 1449 articles screened, seven studies were included. Three articles were awaiting classification, among them, two completed trials identified from the trial registry appeared to be unpublished so far.There were two major comparisons: IV fluid supplementation versus no fluid supplementation (six studies) and IV fluid supplementation versus oral fluid supplementation (one study). A total of 494 term, healthy newborn infants with unconjugated hyperbilirubinaemia were evaluated. All studies were at high risk of bias for blinding of care personnel, five studies had unclear risk of bias for blinding of outcome assessors, and most studies had unclear risk of bias in allocation concealment. There was low- to moderate-quality evidence for all major outcomes.In the comparison between IV fluid supplementation and no supplementation, no infant in either group developed bilirubin encephalopathy in the one study that reported this outcome. Serum bilirubin was lower at four hours postintervention for infants who received IV fluid supplementation (MD -34.00 μmol/L (-1.99 mg/dL), 95% CI -52.29 (3.06) to -15.71 (0.92); participants = 67, study = 1) (low quality of evidence, downgraded one level for indirectness and one level for suspected publication bias). Beyond eight hours postintervention, serum bilirubin was similar between the two groups. Duration of phototherapy was significantly shorter for fluid-supplemented infants, but the estimate was affected by heterogeneity which was not clearly explained (MD -10.70 hours, 95% CI -15.55 to -5.85; participants = 218; studies = 3; I² = 67%). Fluid-supplemented infants were less likely to require exchange transfusion (RR 0.39, 95% CI 0.21 to 0.71; RD -0.01, 95% CI -0.04 to 0.02; participants = 462; studies = 6; I² = 72%) (low quality of evidence, downgraded one level due to inconsistency, and another level due to suspected publication bias), and the estimate was similarly affected by unexplained heterogeneity. The frequencies of breastfeeding were similar between the fluid-supplemented and non-supplemented infants in days one to three based on one study (estimate on day three: MD 0.90 feeds, 95% CI -0.40 to 2.20; participants = 60) (moderate quality of evidence, downgraded one level for imprecision).One study contributed to all outcome data in the comparison of IV versus oral fluid supplementation. In this comparison, no infant in either group developed abnormal neurological signs. Serum bilirubin, as well as the rate of change of serum bilirubin, were similar between the two groups at four hours after phototherapy (serum bilirubin: MD 11.00 μmol/L (0.64 mg/dL), 95% CI -21.58 (-1.26) to 43.58 (2.55); rate of change of serum bilirubin: MD 0.80 μmol/L/hour (0.05 mg/dL/hour), 95% CI -2.55 (-0.15) to 4.15 (0.24); participants = 54 in both outcomes) (moderate quality of evidence for both outcomes, downgraded one level for indirectness). The number of infants who required exchange transfusion was similar between the two groups (RR 1.60, 95% CI 0.60 to 4.27; RD 0.11, 95% CI -0.12 to 0.34; participants = 54). No infant in either group developed adverse effects including vomiting or abdominal distension. AUTHORS' CONCLUSIONS There is no evidence that IV fluid supplementation affects important clinical outcomes such as bilirubin encephalopathy, kernicterus, or cerebral palsy in healthy, term newborn infants with unconjugated hyperbilirubinaemia requiring phototherapy. In this review, no infant developed these bilirubin-associated clinical complications. Low- to moderate-quality evidence shows that there are differences in total serum bilirubin levels between fluid-supplemented and control groups at some time points but not at others, the clinical significance of which is uncertain. There is no evidence of a difference between the effectiveness of IV and oral fluid supplementations in reducing serum bilirubin. Similarly, no infant developed adverse events or complications from fluid supplementation such as vomiting or abdominal distension. This suggests a need for future research to focus on different population groups with possibly higher baseline risks of bilirubin-related neurological complications, such as preterm or low birthweight infants, infants with haemolytic hyperbilirubinaemia, as well as infants with dehydration for comparison of different fluid supplementation regimen.

Abstract
AIMS AND OBJECTIVES To prove the effects of an enteral feeding improvement massage for premature infants with regard to their feeding, growing and superior mesentery artery blood flow aspect by a randomised controlled trial. BACKGROUND Premature infants have feeding-related problems related to eating and absorbing nutrition due to their immature gastrointestinal function. Studies regarding the effectiveness of premature infants' enteral feeding improvement by tactile stimulation massage are rare. DESIGN The study group was composed of 55 patients. Of the 55 patients, 26 were randomised into an experimental group and 29 were randomised into a control group. METHODS They were all born <34 weeks of gestational age between 1 July 2011 and 30 March 2012. Premature infants in the experimental group received enteral feeding improvement massage twice a day for 14 days, and infants in the control group received a sham exercise. The collected data were analysed by spss 19.0, through t test, chi-square test (Fisher's exact) and ANCOVA. RESULTS (i) The experimental group had reached the day of full enteral feeding significantly faster. (ii) The experimental group had a higher superior mesentery artery peak velocity (Vmax ) and lower RI (resistant index). (iii) The experimental group of the feeding-intolerant subgroup had a higher superior mesentery artery Vmax and Vmin . (iv) The experimental group had a heavier weight and larger head circumference after 14 days. CONCLUSIONS This study demonstrates that enteral feeding improvement massage can be helpful for achieving earlier full enteral feeding, more increased superior mesentery artery, and faster growing. In particular, it can be a therapeutic, independent and evidence-based nursing intervention for feeding-intolerant premature infants. RELEVANCE TO CLINICAL PRACTICE Neonatal nurses in neonatal intensive care unit can apply enteral feeding improvement massage massage for feeding-intolerant infants.

Abstract
BACKGROUND In preterm infants fortification of human milk with human milk fortifiers (HMF) to optimize nutrition and growth is standard practice. We compared clinical, nutrition and growth outcomes in infants receiving two types of liquid HMF (LHMF). METHODS Clinical, nutrition and growth outcomes were compared between infants admitted to a level IV NICU, and born with birth weight less than or equal to 1800 grams, between 10/1/2014-12/31/2014 and received human milk with acidified LHMF (ALHMF) and between 1/1/2015-4/31/2015 and received human milk with heat treated LHMF (HTLHMF). RESULTS Of the 85 qualifying infants, 67 received human milk and LHMF. ALHMF group had significantly higher incidence of metabolic acidosis and lower bicarbonate and base excess levels relative to infants receiving HTLHMF (P < 0.001). There were no significant differences by LHMF status in other clinical outcomes and nutrition and growth outcomes. In multivariate analyses, ALHMF use was associated with metabolic acidosis, and lower base excess and bicarbonate levels. CONCLUSION In our study, the clinical, nutrition and growth outcomes between the two LHMF groups were similar. However, use of ALHMF in preterm infants was associated with increased incidence of metabolic acidosis in our cohort. Further randomized control trials are warranted to evaluate these findings.

Abstract
BACKGROUND The perception of smell and taste, though present early in development, is not routinely considered in the care of preterm infants. Smell and taste are known to increase gut motility, insulin secretion, and the release of appetite, digestive and metabolic hormones. OBJECTIVE We aimed to investigate the effect of regular smell and taste on the time from birth to full enteral feeds, and the feasibility of the study protocol in very preterm infants. METHODS In a randomized controlled trial, infants <29 weeks' postmenstrual age (PA) were assigned to receive either the smell and taste of milk before each feed or to have no exposure to the smell and taste of milk (control). RESULTS Infants in the treatment group (n = 28) and control group (n = 23) were born at a mean (SD) PA of 26.7 (1.5) and 27.2 (1.4) weeks, respectively. They reached full enteral feeds at a median (IQR) of 13.5 (10.0-19.0) and 15.5 (11.0-22.0) days, respectively. Survival analysis showed an adjusted hazard ratio of 1.63 (95% confidence interval 0.91-2.91; p = 0.10) for the effect on the time to establish full enteral feeds. Repeated-measures analysis indicated significant group differences in weight z scores at 36 weeks' PA and at discharge in favor of the intervention (p < 0.05). CONCLUSION These data indicate that the smell and taste of milk may improve milk tolerance and weight in preterm infants. The role of regular smell and taste in promoting enteral nutrition and growth in preterm infants merits a larger trial powered to detect important outcomes.

Abstract
BACKGROUND Preterm infants are at increased risk of developing feeding intolerance and necrotizing enterocolitis. Comprehensive, targeted nursing assessments can evaluate the risk for and identify early signs of these conditions in an effort to prevent their destructive sequela. PURPOSE While the long-term goal is to develop a validated risk-scoring tool for the prediction of feeding intolerance and necrotizing enterocolitis, the objective of the preliminary phase presented here is to assess the ease of use and nurses' attitudes toward a novel feeding intolerance and necrotizing enterocolitis risk-scoring tool. METHODS A novel risk-scoring nursing tool was implemented in a University of Illinois-affiliated 48-bed level III neonatal intensive care unit. Data were collected from the electronic medical record of all preterm infants with parental consent during the initial 6-month study period. Scoring accuracy (accuracy of selection of risk factors based on electronic medical record data), ease of use, and nurses' attitudes toward the tool were assessed at the study site and by evaluators at a national neonatal nursing conference. RESULTS Fourteen nurses scored 166 tools on the 63 enrolled infants. Sixteen tools (9.6%) contained errors. Mean study site tool ease of use was 8.1 (SD: 2.2) on a 10-point scale. Ninety percent of conference evaluators agreed/strongly agreed that the tool addressed important knowledge gaps. IMPLICATIONS FOR PRACTICE The tool is easy to use and valued by nurses. Following validation, widespread implementation is expected to be a clinically feasible means to improve infant clinical outcomes for minimal time and financial cost. IMPLICATIONS FOR RESEARCH Tool validation and refinement based on nursing feedback will improve its broad applicability and predictive utility.

Abstract
The goal of preterm nutrition in achieving growth and body composition approximating that of the fetus of the same postmenstrual age is difficult to achieve. Current nutrition recommendations depend largely on expert opinion, due to lack of evidence, and are primarily birth weight based, with no consideration given to gestational age and/or need for catch-up growth. Assessment of growth is based predominately on anthropometry, which gives insufficient attention to the quality of growth. The present paper provides a review of the current literature on the nutritional management and assessment of growth in preterm infants. It explores several approaches that may be required to optimise nutrient intakes in preterm infants, such as personalising nutritional support, collection of nutrient intake data in real-time, and measurement of body composition. In clinical practice, the response to inappropriate nutrient intakes is delayed as the effects of under- or overnutrition are not immediate, and there is limited nutritional feedback at the cot-side. The accurate and non-invasive measurement of infant body composition, assessed by means of air displacement plethysmography, has been shown to be useful in assessing quality of growth. The development and implementation of personalised, responsive nutritional management of preterm infants, utilising real-time nutrient intake data collection, with ongoing nutritional assessments that include measurement of body composition is required to help meet the individual needs of preterm infants.

Abstract
BACKGROUND Feeding intolerance is a common clinical problem among preterm infants. It may be an early sign of necrotising enterocolitis, sepsis or other serious gastrointestinal conditions, or it may result from gut immaturity with delayed passage of meconium. Glycerin laxatives stimulate passage of meconium by acting as an osmotic dehydrating agent and increasing osmotic pressure in the gut; they stimulate rectal contraction, potentially reducing the incidence of feeding intolerance. OBJECTIVES To assess the effectiveness and safety of glycerin laxatives (enemas/suppositories) for prevention or treatment of feeding intolerance in very low birth weight (VLBW) infants. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 4), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We restricted our search to all randomised controlled trials and applied no language restrictions. We searched the references of identified studies and reviews on this topic and handsearched for additional articles. We searched the database maintained by the US National Institutes of Health (www.clinicaltrials.gov) and European trial registries to identify ongoing trials. SELECTION CRITERIA We considered only randomised or quasi-randomised controlled trials that enrolled preterm infants < 32 weeks' gestational age (GA) and/or < 1500 g birth weight. We included trials if they administered glycerin laxatives and measured at least one prespecified clinical outcome. DATA COLLECTION AND ANALYSIS We used standard methods of The Cochrane Collaboration and its Neonatal Group to assess methodological quality of trials, to collect data and to perform analyses. MAIN RESULTS We identified three trials that evaluated use of prophylactic glycerin laxatives in preterm infants. We identified no trials that evaluated therapeutic use of glycerin laxatives for feeding intolerance. Our review showed that prophylactic administration of glycerin laxatives did not reduce the time required to achieve full enteral feeds and did not influence secondary outcomes, including duration of hospital stay, mortality and weight at discharge. Prophylactic administration of glycerin laxatives resulted in failure of fewer infants to pass stool over the first 48 hours. Included trials reported no adverse events. AUTHORS' CONCLUSIONS Our review of available evidence for glycerin laxatives does not support the routine use of prophylactic glycerin laxatives in clinical practice. Additional studies are needed to confirm or refute the effectiveness and safety of glycerin laxatives for prevention or treatment of feeding intolerance in VLBW infants.

Abstract
OBJECTIVE To develop an evidence-based feeding bundle to safely decrease the rate of PNGR in VLBW infants. STUDY DESIGN The bundle was developed and implemented in January 2010, followed by 3 years of monitoring bundle compliance and infant outcomes (days to first feed (FD), days to reach full feeds (FF), and birth-discharge growth trajectories (delta z-score)). RESULTS Data were collected on 482 infants (119 pre-bundle). PNGR decreased from 35% to 19% (P<0.01) and weight delta z-score improved from -0.82 to -0.45 (P<0.001). Percentage of infants with head circumference (HC) below 10th percentile at discharge decreased from 21% to 9% (P<0.01) and HC delta z-score improved from -0.65 to -0.17 (P<0.001). FD and FF also decreased significantly. Rates of necrotizing enterocolitis, peak alkaline phosphatase and peak direct bilirubin levels all trended downward. CONCLUSIONS An evidence-based, standardized feeding bundle was safe and effective in reducing the rate of PNGR and in improving head growth in VLBW infants.

Abstract
BACKGROUND While various feeding strategies designed to optimize growth have been investigated and used in the clinical setting, the problem of not being able to recognize the warning signs of feeding intolerance early enough to prevent serious gastrointestinal complication commonly associated with very low birth-weight (VLBW) preterm infant remains. Currently, early stages of feeding intolerance are most often identified though nurse assessments. Additional methods to predict feeding intolerance in this population are needed. Currently, intra-abdominal pressure monitoring has been an effective method to predict intolerance to enteral nutrition in the adult and pediatric populations. PURPOSE There is supportive evidence for the use of noninvasive methods, such as nasogastric tubes, to effectively monitor IAP. While this may not be the gold standard method of using Foley catheters for measurement, it could provide predictive levels that are indicative of progression toward bowel inflammation. FINDINGS This review shows the potential for using noninvasive nasogastric tubes for monitoring intra-abdominal pressure and may provide direction for evaluating intra-abdominal pressures in VLBW preterm infants as a reliable method for early identification of feeding intolerance. IMPLICATIONS FOR PRACTICE The use of nasogastric tubes to monitor intra-abdominal pressure may provide an effective noninvasive tool to identify VLBW preterm infants progressing toward feeding intolerance and would add to assessment data. IMPLICATIONS FOR RESEARCH Development and testing of a reliable nasogastric tube monitoring device in the VLBW preterm infant population and identify predictive levels that indicate progression toward feeding intolerance is needed. Once IAP predictive levels are identified, provider interventions could be developed.

Abstract
BACKGROUND AND SIGNIFICANCE Risk for neonatal necrotizing enterocolitis (NEC) is complex, reflecting its multifactorial pathogenesis. PURPOSE To improve risk awareness and facilitate communication among neonatal caregivers, especially nurses, 2 tools were developed. DESIGN GutCheck was derived and validated as part of a formal research study over 3 phases, evidence synthesis, expert consensus building, and statistical modeling. The Wetzel/Krisman tool, eNEC, was developed and tested as part of a quality improvement initiative in a single clinical setting using evidence synthesis, review by internal expert clinicians, and implementation and evaluation of its use by direct line neonatal staff. Refinement of both tools is under way to evaluate their effect on clinical decision making, early identification of NEC and surgical NEC. METHODS AND MAIN OUTCOMES Clinicians can take an active role to reduce NEC in their units by focusing on modifiable risk factors such as adoption of standardized feeding protocols, preferential feeding of human milk, and antibiotic and histamine blocker stewardship. RESULTS Feeding during transfusion remains controversial, but judicious use of transfusions, adoption of transfusion guidelines, and withholding feeding during transfusion are feasible measures with potential benefit to prevent NEC and confer little risk.

Abstract
OBJECTIVE The aim of this study was to compare the effect of administration of probiotics on feeding tolerance and growth outcomes of HIV-exposed (but uninfected) versus HIV non-exposed preterm infants. The null hypothesis of this study states that there will be no difference in the feeding tolerance and growth outcomes for both probiotic-exposed and unexposed premature very low birth weight infants. METHODS A randomized, double-blind, placebo-controlled trial was conducted during the period from July 2011 to August 2012. HIV-exposed and non-exposed premature (<34 wk gestation) infants with a birth weight of ≥500 g and ≤1250 g were randomized to receive either a probiotic mixture or placebo. The multispecies probiotic mixture consisted of 1 × 10(9) CFU, Lactobacillus rhamnosus GG and Bifidobacterium infantis per day and was administered for 28 d. Anthropometrical parameters, daily intakes, and feeding tolerance were monitored. RESULTS Seventy-four HIV-exposed and 110 unexposed infants were enrolled and randomized (mean birth weight 987 g ± 160 g, range, 560-1244 g; mean gestational age 28.7 wk). In all 4227 probiotic doses were administered (mean 22.9/infant). There was no difference in the average daily weight gain for treatment groups or HIV exposure. The HIV-exposed group achieved significantly higher z scores for length and head circumference at day 28 than the unexposed group (P < 0.01 and P = 0.03, respectively). There were no differences in the incidence of any signs of feeding intolerance and abdominal distension between the groups. CONCLUSION Probiotic supplementation did not affect growth outcomes or the incidence of any signs of feeding intolerance in HIV exposure.

Abstract
UNLABELLED Feeding intolerance (FI) is usually defined as "gastric residual volume of more than 50 % of the previous feeding volume, emesis, abdominal distension or both of these symptoms and a decrease, delay or discontinuation of enteral feedings." We aimed to compare the incidence of FI in preterm infants fed with powdered or liquid infant formula, and in a prospective, double-blind, pilot study, 78 preterm infants were randomized to receive powdered or liquid form of the same preterm infant formula. The primary outcomes were the incidence of FI in both groups. The pH of gastric fluids was measured in the fasting and postprandial periods on the seventh day of life, and gastrointestinal complications were recorded during the hospitalization period. The incidence of FI was significantly higher in infants fed with liquid formula (n = 34) when compared with infants fed with powdered formula (n = 44) [9 (26.5 %) vs 2 (4.5 %), p < 0.01, respectively]. The median fasting gastric fluid pH was significantly lower and postprandial gastric fluid pH was significantly higher than in infants fed with powdered formula (2.9 vs 3.4, p < 0.01 and 6.0 vs 5.9, p < 0.05 respectively). Infants fed with liquid formula regained birth weight significantly later than infants fed with powdered formula (9.5 vs 8.0 days, p < 0.01). CONCLUSION Although the exact mechanisms are not clear, increased incidence of FI and delayed growth in the first weeks of life in preterm infants fed with liquid formula might be caused by altered gastric acidity or possible disrupted protein bioavailability due to different production and sterilization processes.

Abstract
BACKGROUND Erythromycin is generally used as a prokinetic agent for the treatment of feeding intolerance in preterm infants; however, results from previous studies significantly vary due to different medication dosages, routes of administration, and therapy durations. The effectiveness and safety of intermediate-dose oral erythromycin in very low birth weight (VLBW) infants with feeding intolerance was examined in this study. METHODS Between November 2007 and August 2009, 45 VLBW infants with feeding intolerance, who were all at least 14 days old, were randomly allocated to a treatment group and administered 5mg/kg oral erythromycin every 6hours for 14 days (n=19). Another set of randomly selected infants was allocated to the control group, which was not administered erythromycin (n=26). RESULTS The number of days required to achieve full enteral feeding (36.5±7.4 vs. 54.7±23.3 days, respectively; p=0.01), the duration of parenteral nutrition (p<0.05), and the time required to achieve a body weight ≥2500g (p<0.05) were significantly shorter in the erythromycin group compared with the control group. The incidence of parenteral nutrition-associated cholestasis (PNAC) and necrotizing enterocolitis (NEC) ≥ stage II after 14 days of treatment were significantly lower (p<0.05) in the erythromycin group. No significant differences were observed in terms of the incidences of sepsis, bronchopulmonary dysplasia, or retinopathy of prematurity. No adverse effects were associated with erythromycin treatment. CONCLUSIONS Intermediate-dose oral erythromycin is effective and safe for the treatment of feeding intolerance in VLBW infants. The incidences of PNAC and ≥ stage II NEC were significant lower in the erythromycin group.

Abstract
BACKGROUND Current evidence indicates that probiotic supplementation significantly reduces all-cause mortality and definite necrotising enterocolitis without significant adverse effects in preterm neonates. As the debate about the pros and cons of routine probiotic supplementation continues, many institutions are satisfied with the current evidence and wish to use probiotics routinely. Because of the lack of detail on many practical aspects of probiotic supplementation, clinician-friendly guidelines are urgently needed to optimise use of probiotics in preterm neonates. AIM To develop evidence-based guidelines for probiotic supplementation in preterm neonates. METHODS To develop core guidelines on use of probiotics, including strain selection, dose and duration of supplementation, we primarily used the data from our recent updated systematic review of randomised controlled trials. For equally important issues including strain identification, monitoring for adverse effects, product format, storage and transport, and regulatory hurdles, a comprehensive literature search, covering the period 1966-2010 without restriction on the study design, was conducted, using the databases PubMed and EMBASE, and the proceedings of scientific conferences; these data were used in our updated systematic review. RESULTS In this review, we present guidelines, including level of evidence, for the practical aspects (for example, strain selection, dose, duration, clinical and laboratory surveillance) of probiotic supplementation, and for dealing with non-clinical but important issues (for example, regulatory requirements, product format). Evidence was inadequate in some areas, and these should be a target for further research. CONCLUSION We hope that these evidence-based guidelines will help to optimise the use of probiotics in preterm neonates. Continued research is essential to provide answers to the current gaps in knowledge about probiotics.

Abstract
Feeding intolerance is a well-known phenomenon in the NICU and is linked to morbidity and mortality in the premature infant. However, a universal definition for this concept is lacking. Properly defining a concept is a key step in a successful research project. A concept analysis is an examination of the fundamental elements of a concept to bring clarification and definition to the topic of interest. The purpose of this concept analysis was to clarify the phenomenon of feeding intolerance in the premature infant and to provide a universal conceptual and operational definition for researchers and clinicians to use in practice theory.

Abstract
OBJECTIVE The objective of this study was to evaluate the impact of a standardized enteral feeding protocol for very low birth weight (VLBW) infants on nutritional, clinical and growth outcomes. STUDY DESIGN Retrospective analysis of VLBW cohorts 9 months before and after initiation of a standardized feeding protocol consisting of 6-8 days of trophic feedings, followed by an increase of 20 ml/kg/day. The primary outcome was days to reach full enteral feeds defined as 160 ml/kg/day. Secondary outcomes included rates of necrotizing enterocolitis and culture-proven sepsis, days of parenteral nutrition and growth end points. RESULT Data were analyzed on 147 VLBW infants who received enteral feedings, 83 before ('Before') and 64 subsequent to ('After') feeding protocol initiation. Extremely low birth weight (ELBW) infants in the After group attained enteral volumes of 120 ml/kg/day (43.9 days Before vs 32.8 days After, P=0.02) and 160 ml/kg/day (48.5 days Before vs 35.8 days After, P=0.02) significantly faster and received significantly fewer days of parenteral nutrition (46.2 days Before vs 31.3 days After, P=0.01). Necrotizing enterocolitis decreased in the After group among VLBW (15/83, 18% Before vs 2/64, 3% After, P=0.005) and ELBW infants (11/31, 35% Before vs 2/26, 8% After, P=0.01). Late-onset sepsis decreased significantly in the After group (26/83, 31% Before vs 6/64, 9% After, P=0.001). Excluding those with weight <3rd percentile at birth, the proportion with weight <3rd percentile at discharge decreased significantly after protocol initiation (35% Before vs 17% After, P=0.03). CONCLUSION These data suggest that implementation of a standardized feeding protocol for VLBW infants results in earlier successful enteral feeding without increased rates of major morbidities.

Abstract
BACKGROUND Feed intolerance delays achievement of enteral feeding in preterm infants. Parenteral nutrition is associated with cholestasis and increased risk of sepsis. Glycerin suppositories have been used to promote gastrointestinal motility and feed tolerance. OBJECTIVES To investigate whether daily glycerin suppositories (a) reduce the time to full enteral feeding in infants born at <32 weeks' gestation, and (b) influence feed tolerance, incidence of sepsis or necrotizing enterocolitis, duration of oxygen requirement, growth or age at discharge. METHODS Design - prospective open randomized controlled trial; study population - preterm infants stratified into 2 subgroups, 24-27(+6) weeks (24-27 weeks + 6 days) and 28-31(+6) weeks; intervention - daily glycerin suppository for 10 days from 24 h of age, 250 mg (24-27(+6) weeks subgroup) or 500 mg (two 250-mg suppositories; 28-31(+6) weeks subgroup); controls - no intervention. The same feeding protocol and departmental guidelines for other aspects of neonatal intensive care were used in all subjects. Analysis was by intention to treat. RESULTS 54 babies were recruited (31 males), 29 randomized to receive suppositories; 48 achieved full enteral feeds. The median (range) time to full feeds was 1.6 days shorter in intervention group babies than controls, but not statistically significant: 7.4 (4.6-30.9) days versus 9.0 (4.4-13.3) days (p = 0.780; 95% confidence interval: -1.917, 2.166). No significant differences were observed in secondary outcomes. Intervention group babies passed their first stool earlier than controls (median: day 2 vs. day 4; p = 0.016). CONCLUSION Regular glycerin suppositories did not reduce the time to full enteral feeds in infants born at <32 weeks' gestation in our setting.

Abstract
The gastrointestinal inflammatory disorder, necrotizing enterocolitis (NEC), is among the most serious diseases for preterm neonates. Nutritional, microbiological and immunological dysfunctions all play a role in disease progression but the relationship among these determinants is not understood. The preterm gut is very sensitive to enteral feeding which may either promote gut adaptation and health, or induce gut dysfunction, bacterial overgrowth and inflammation. Uncontrolled inflammatory reactions may be initiated by maldigestion and impaired mucosal protection, leading to bacterial overgrowth and excessive nutrient fermentation. Tumor necrosis factor alpha, toll-like receptors and heat-shock proteins are identified among the immunological components of the early mucosal dysfunction. It remains difficult, however, to distinguish the early initiators of NEC from the later consequences of the disease pathology. To elucidate the mechanisms and identify clinical interventions, animal models showing spontaneous NEC development after preterm birth coupled with different forms of feeding may help. In this review, we summarize the literature and some recent results from studies on preterm pigs on the nutritional, microbial and immunological interactions during the early feeding-induced mucosal dysfunction and later NEC development. We show that introduction of suboptimal enteral formula diets, coupled with parenteral nutrition, predispose to disease, while advancing amounts of mother's milk from birth (particularly colostrum) protects against disease. Hence, the transition from parenteral to enteral nutrition shortly after birth plays a pivotal role to secure gut growth, digestive maturation and an appropriate response to bacterial colonization in the sensitive gut of preterm neonates.

Abstract
OBJECTIVE The aim of this study was to determine the function of newborn nurses given at newborn feeding in the newborn units of public hospitals in Konya, Turkey, besides it was also to determine the effect of nurses which had short-term training, aka education, in practice and in theory. METHODS This was an experimental study conducted with a total of 50 newborn nurses between 15 September 2004 and 30 February 2005. In collecting the data, a survey sheet including the demographic characteristics of newborn nurses and their knowledge on newborn feeding was applied, along with another remark form that shows clinical practices about newborn feeding. RESULTS Considering the nurses, their knowledge mean score 'after education (AE)' was calculated to be 72.4 ± 10.4, which was significantly higher than that of 'before education (BE)', which was 58.0 ± 9.3, (p < 0.05). Likewise, the implementation mean score of these nurses AE (57.2 ± 4.9) was also found higher than the mean score BE (54.4 ± 5.0) (p < 0.05). There were statistically significant differences in the posteducation mean scores of nurses for the number of children they had, and for the hospital they work. CONCLUSION In this study, it was determined that the nurses had knowledge deficits about newborn feeding both in theory and practice, but after a short educational program on newborn feeding their theoretical and practical knowledge had shown increases.

Abstract
OBJECTIVE Systematic reviews of randomized, controlled trials (RCTs) indicate lower mortality and necrotizing enterocolitis (NEC) and shorter time to full feeds after probiotic supplementation in preterm (<34 weeks' gestation) very low birth weight (VLBW; birth weight <1500 g) neonates. The objective of this study was to update our 2007 systematic review of RCTs of probiotic supplementation for preventing NEC in preterm VLBW neonates. METHODS We searched in March 2009 the Cochrane Central register; Medline, Embase, and Cinahl databases; and proceedings of the Pediatric Academic Society meetings and gastroenterology conferences. Cochrane Neonatal Review Group search strategy was followed. Selection criteria were RCTs of any enteral probiotic supplementation that started within first 10 days and continued for > or =7 days in preterm VLBW neonates and reported on stage 2 NEC or higher (Modified Bell Staging). RESULTS A total of 11 (N = 2176), including 4 new (n = 783), trials were eligible for inclusion in the meta-analysis by using a fixed-effects model. The risk for NEC and death was significantly lower. Risk for sepsis did not differ significantly. No significant adverse effects were reported. Trial sequential analysis) showed 30% reduction in the incidence of NEC (alpha = .05 and .01; power: 80%). CONCLUSIONS The results confirm the significant benefits of probiotic supplements in reducing death and disease in preterm neonates. The dramatic effect sizes, tight confidence intervals, extremely low P values, and overall evidence indicate that additional placebo-controlled trials are unnecessary if a suitable probiotic product is available.

Abstract
OBJECTIVE Indomethacin and ibuprofen are administered to preterm neonates for symptomatic patent ductus arteriosus. The drugs suppress prostaglandins (PGs) which modulate growth and secretion of various hormones. We examined the hypothesis that early postnatal indomethacin and ibuprofen influence growth and GH-IGF-I-insulin and HPA axes in neonatal rats. DESIGN Rat pups received IP injections of saline (Sal) on P1, P2, and P3; 10mg/kg ibuprofen on P1 followed by 5mg/kg on P2 and P3; or 0.2mg/kg indomethacin on P1 followed by 0.1mg/kg on P2 and P3. Serum and hepatic GH, GHBP and IGF-I; and serum corticosterone and insulin levels were determined. RESULTS Ibuprofen suppressed somatic growth in the sucking rats, but the effect was transient, resolving by P14. Indomethacin had an opposite, latent effect on body weight and liver to body weight ratios in weanling rats. Both indomethacin and ibuprofen had profound hormonal effects that differed in magnitude and timing. Indomethacin resulted in a sustained elevation in corticosterone levels at P21, while ibuprofen increased serum and hepatic GH levels. Both drugs suppressed GHBP in serum at P7 and P14; and liver at P4 and P7, but a rebound increase in serum GHBP was noted at P21 with Ibuprofen only. Both drugs increased serum IGF-I at P7. The effect remained sustained with indomethacin. CONCLUSIONS These results provide evidence for an involvement of PGs in the regulation of growth as well as the GH-IGF and HPA axes. Therefore, early postnatal exposure to PG inhibitors may further exacerbate postnatal growth restriction and ability to cope with stress.

Abstract
AIM To establish the roles of lipopolysaccharide (LPS)/CD14/toll-like receptor 4 (TLR4)-mediated inflammation in a rat model of human necrotizing enterocolitis (NEC). METHODS Six pairs of intestinal samples from human NEC were collected before and after recovery for histological and molecular analysis of inflammatory cytokines and signaling components. In the rat NEC model, we isolated 10-cm jejunum segments and divided them into six groups (n = 6) for sham operation, treatment with LPS, bowel distension, combined bowel distension and LPS stimulation, and two therapeutic groups. The potential efficacy of a recombinant CD18 peptide and a monoclonal CD14 antibody was evaluated in the latter two groups. The serum and tissue levels of several inflammatory mediators were quantified by real-time polymerase chain reaction, ELISA and immunoblotting. RESULTS Human acute phase NEC tissues displayed significant increases (P < 0.05) in levels of TLR4, CD14, myeloid differentiation protein (MD)-2, tumor necrosis factor (TNF)-alpha and nuclear factor-kappaB when compared to those after recovery. The histological and inflammatory picture of human NEC was reproduced in rats that were treated with combined bowel distension and LPS, but not in the sham-operated and other control rats. Serum levels of interleukin-6 and TNF-alpha were also elevated. The NEC pathology was attenuated by treating the NEC rats with a monoclonal CD14 antibody or an LPS-neutralizing peptide. CONCLUSION LPS and distension are required to produce the histological and inflammatory features of NEC. A potential treatment option is blocking LPS activation and leukocyte infiltration.

Does the enteral feeding advancement affect short-term outcomes in very low birth weight infants? J Pediatr Gastroenterol Nutr 2009; 48:464-70.

Abstract
BACKGROUND AND OBJECTIVES Controversy exists regarding the optimal enteral feeding regimen of very low birth weight infants (VLBW). Rapid advancement of enteral feeding has been associated with an increased rate of necrotizing enterocolitis. In contrast, delaying enteral feeding may have unfavorable effects on nutrition, growth, and neurodevelopment. The aim is to compare the short-term outcomes of VLBW infants in tertiary care centers according to their enteral feeding advancement. PATIENTS AND METHODS We prospectively studied the influence of center-specific enteral feeding advancement in 1430 VLBW infants recruited from 13 tertiary neonatal intensive care units in Germany on short-term outcome parameters. The centers were post hoc stratified to "rapid advancement to full enteral feeds" (median duration of advancement to full enteral feeds < or =12.5 days; 6 centers), that is, rapid advancement (RA), or "slow advancement to full enteral feeds" (median duration of advancement to full enteral feeds >12.5 days; 7 centers), that is, slow advancement (SA). RESULTS VLBW infants born in centers with SA (n = 713) had a significantly higher rate of sepsis compared with VLBW infants born in centers with RA (n = 717), which was particularly evident for late-onset sepsis (14.0% vs 20.4%; P = 0.002). Furthermore, more central venous lines (48.6% vs 31.1%, P < 0.001) and antibiotics (92.4% vs 77.7%, P < 0.001) were used in centers with SA. CONCLUSIONS Center differences in enteral feeding advancement occur and may have a significant impact on short-term outcomes such as nosocomial sepsis. Large, multicenter, prospective trials are required to further elucidate the optimal feeding strategy for VLBW infants.

J Pediatr Surg 2008; 43:e5-8. [PMID: 18405699 DOI: 10.1016/j.jpedsurg.2007.11.034] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2007] [Revised: 11/12/2007] [Accepted: 11/14/2007] [Indexed: 11/26/2022]
Abstract
Infections with adenoviruses are a common problem in the pediatric population. Normally asymptomatic to mild, those infections tend to take a more severe course in immunocompromised patients. 22q11 deletion syndrome (22q11DS) represents a common genetic disorder causing immunodeficiency from thymic hypoplasia or aplasia, heart defects, a characteristic facial appearance, and velopharyngeal dysfunction. Necrotizing enterocolitis (NEC) is a frequent gastrointestinal emergency observed in neonatal intensive care units. The occurrence of NEC is more prevalent in preterm infants. However, there are cases in term infants, but usually, they are associated with predisposing disorders. In this case report, a child is presented with 22q11DS that postnatally developed NEC associated with an adenoviral infection. Although other viruses such as toroviruses or cytomegaloviruses have been implicated in the pathogenesis of NEC in preterm infants, we could not find any report in the recent medical literature describing an association between adenoviral infections, NEC, and 22q11DS in a term infant.

Abstract
Necrotizing enterocolitis (NEC) is a leading cause of morbidity and mortality among infants in the neonatal intensive care unit. Here we review the epidemiology and pathophysiology of NEC, with an emphasis on the latest research findings and potential areas for future research. NEC continues to be one of the most devastating and unpredictable diseases affecting premature infants. Despite decades of research, the pathogenesis of this disease remains unclear, and prevention and treatment strategies are limited. Hopefully, future studies aimed at understanding premature intestinal defenses, commensal or probiotic bacterial influences, and possible genetic predisposition will lead to the improvement of prevention and treatment strategies.

Abstract
Necrotising enterocolitis is one of the most common gastrointestinal emergencies in newborn infants. Here we review the epidemiology, clinical presentation, and pathophysiology of the disease, as well as strategies for diagnosis, management, and prevention. Necrotising enterocolitis is one of the most devastating and unpredictable diseases affecting premature infants. Despite decades of research, its pathogenesis remains unclear; diagnosis can be difficult; and treatment is challenging. We will need to improve our understanding of intestinal defences in premature infants, dietary and bacterial factors, and genetic effects that could predispose infants to necrotising enterocolitis before we can develop new strategies for prevention and treatment.
