Abstract
ImportanceProphylactic cyclo-oxygenase inhibitors (COX-Is) such as indomethacin, ibuprofen and acetaminophen may prevent morbidity and mortality in extremely preterm infants (born ≤28 weeks' gestation). However, there is controversy around which COX-I, if any, is the most effective and safest, which has resulted in considerable variability in clinical practice. Our objective was to develop rigorous and transparent clinical practice guideline recommendations for the prophylactic use of COX-I drugs for the prevention of mortality and morbidity in extremely preterm infants. The Grading of Recommendations Assessment, Development and Evaluation evidence-to-decision framework for multiple comparisons was used to develop the guideline recommendations. A 12-member panel, including 5 experienced neonatal care providers, 2 methods experts, 1 pharmacist, 2 parents of former extremely preterm infants and 2 adults born extremely preterm, was convened. A rating of the most important clinical outcomes was established a priori. Evidence from a Cochrane network meta-analysis and a cross-sectional mixed-methods study exploring family values and preferences were used as the primary sources of evidence. The panel recommended that prophylaxis with intravenous indomethacin may be considered in extremely preterm infants (conditional recommendation, moderate certainty in estimate of effects). Shared decision making with parents was encouraged to evaluate their values and preferences prior to therapy. The panel recommended against routine use of ibuprofen prophylaxis in this gestational age group (conditional recommendation, low certainty in the estimate of effects). The panel strongly recommended against use of prophylactic acetaminophen (strong recommendation, very low certainty in estimate of effects) until further research evidence is available.

Abstract
OBJECTIVE Spontaneous intestinal perforation (SIP) occurs commonly in extremely low gestational age newborns (ELGANs; <30 weeks' GA). Early, concurrent neonatal use of indomethacin (Neo_IN) and hydrocortisone (Neo_HC) is a known risk for SIP. Mothers in premature labor often receive indomethacin (Mat_IN) for tocolysis and steroids (Mat_S) for fetal maturation. Coincidentally, ELGANs may receive Neo_IN or Neo_HC within the first week of life. There are limited data on the effect of combined exposures to maternal and neonatal medications. We hypothesized that proximity exposure to these medications may increase the risk of SIP. STUDY DESIGN We reviewed the medical records of ELGANs from June 2014 to December 2019 at a single level III neonatal intensive care unit. We compared antenatal and postnatal indomethacin and steroid use between neonates with and without SIP. For analysis, chi-square, Student's t-test, Fisher's exact test, and Mann-Whitney U tests were used. RESULTS Among 417 ELGANs, SIP was diagnosed in 23, predominantly in neonates < 26 weeks' GA (n = 21/126, 16.7%). Risk factors analysis focused on this GA cohort in which SIP was most prevalent. Mat_IN administration within 2 days of delivery increased SIP risk (odds ratio: 3; 95% confidence interval: 1.25-7.94; p = 0.036). Neo_HC was not independently associated with SIP (p = 0.38). A higher proportion of SIP group had close temporal exposure of Mat_IN and Neo_HC compared with the non-SIP group, though not statistically significant (14 vs. 7%, p = 0.24). CONCLUSION Peripartum Mat_IN was associated with increased risk for SIP in this small study sample. Larger studies are needed to further delineate SIP risk from the interaction of peripartum maternal medication with early postnatal therapies and disease pathophysiology. KEY POINTS · Perinatal indomethacin is associated with SIP in preterm infants born at less than 26 weeks.. · Temporal proximity of prenatal/postnatal medication exposure matters.. · Indomethacin and Hydrocortisone the risks, benefits, and timing related to SIP..

Abstract
OBJECTIVE To determine if intestinal perforations before 14 days (either spontaneous (SIP) or necrotizing enterocolitis-induced) are increased when infants who received antenatal betamethasone shortly before birth are treated with prophylactic indomethacin (PINDO). STUDY DESIGN Observational study of 475 infants <28 week's gestation assigned to either a PINDO-protocol (n = 231) or expectant management protocol (n = 244) during consecutive protocol epochs. RESULTS Intestinal perforations before 14 days occurred in 33/475 (7%). In unadjusted and adjusted models, we found no associations between PINDO-protocol and intestinal perforations. PINDO-protocol did not increase intestinal perforations or SIP-alone even when given to infants who received betamethasone <7 or <2 days before delivery. 213/231 (92%) PINDO-protocol infants actually received indomethacin. The results were unchanged when examined just in those who received indomethacin. CONCLUSION In our study, early intestinal perforations and SIP-alone were not increased when PINDO was used by protocol in infants who received antenatal betamethasone shortly before birth.

Abstract
OBJECTIVE To estimate if the odds of spontaneous intestinal perforation (SIP) are increased when antenatal steroids (ANS) given close to delivery are combined with indomethacin on day 1 after birth (Indo-D1). STUDY DESIGN A retrospective cohort study using the Neonatal Research Network (NRN) database of inborn infants, gestational age 220-286 weeks or birth weight of 401-1000 g, born between January 1, 2016 and December 31, 2019, and surviving >12 hours. The primary outcome was SIP through 14 days. Time of last ANS dose prior to delivery was analyzed as a continuous variable (using 169 hours for durations >168 hours or no steroid exposure). Associations between ANS, Indo-D1, and SIP were obtained from a multilevel hierarchical generalized linear mixed model after covariate adjustment. This yielded aOR and 95% CI. RESULTS Of 6851 infants, 243 had SIP (3.5%). ANS exposure occurred in 6393 infants (93.3%) and IndoD1 was given to 1863 infants (27.2%). The time (median, IQR) from last dose of ANS to delivery was 32.5 hours (6-81) vs 37.1 hours (7-110) for infants with or without SIP, respectively (P = .10). Indo-D1 was given to 51.9 vs 26.3% of infants with SIP vs no SIP, respectively (P < .0001). Adjusted analysis indicated no interaction between time of last ANS dose and Indo-D1 for SIP (P = .7). Indo-D1 but not ANS was associated with increased odds of SIP (aOR: 1.73, 1.21-2.48, P = .003). CONCLUSION The odds of SIP were increased after receipt of Indo-D1. Exposure to ANS prior to Indo-D1 was not associated with an increase in SIP.

Abstract
Introduction Spontaneous intestinal perforation (SIP) is a poorly understood severe gastrointestinal complications of prematurity which is poorly understood. Extremely premature infants born prior to 28 weeks' gestation develop a localized perforation of the terminal ileum during the first week of life and therapy involves surgery and cessation of enteral feeds. Little is known regardj g the impact of mucosal immune dysfunction on disease pathogenesis. Methods We performed mass cytometry time of flight (CyTOF) of small intestinal mucosa of patients with SIP (Gestational age (GA) 24 - 27 weeks, n=8) compared to patients who had surgery for non-SIP conditions (neonatal (GA >36 weeks, n=5 ) and fetal intestine from elective terminations (GA 18-21 weeks, n=4). CyTOF analysis after stimulation of T cells with PMA/Ionomycin was also performed. Results We noted changes in innate and adaptive mucosal immunity in SIP. SIP mucosa had an expansion of ckit+ neutrophils, an influx of naïve CD4 and CD8 T cells and a reduction of effector memory T cells. SIP T cells were characterized by reduced CCR6 and CXCR3 expression and increased interferon gamma expression after stimulation. Discussion These findings suggest that previously unrecognized immune dysregulation is associated with SIP and should be explored in future studies.

Abstract
OBJECTIVE To assess whether either duration and magnitude of ductal shunt or medical treatment for patent ductus arteriosus (PDA) are related to spontaneous intestinal perforation (SIP). STUDY DESIGN Clinical charts of infants <29 weeks' gestation born from 2006 to 2018 were reviewed. Echocardiographic examinations were evaluated according to McNamara and Sehgal's staging system. RESULTS A higher percentage of patients with SIP had a hemodynamically significant PDA (HSPDA) and was treated with either NSAIDs or paracetamol (79% vs 53% and 81% vs 54%, respectively). Among non-treated patients, we found a 1.32 increase in the odds of SIP per day of persistence of HSPDA. In the cohort of patients treated despite the absence of HSPDA, we found a 2.35 increase in the odds of SIP per dose of drug administered. CONCLUSION Both treating a non-HSPDA and leaving a HSPDA to its natural history seem to be associated with SIP.

Abstract
BACKGROUND There is limited information about the mortality and neurodevelopmental outcomes of very preterm infants (<32 weeks) with spontaneous intestinal perforation (SIP). OBJECTIVE To explore the association between SIP and neurodevelopmental outcomes and mortality in very preterm infants. DATA SOURCES Medline, EMBASE, Cochrane Library, EMCARE and MedNar. STUDY SELECTION Databases were searched until September 2021. Studies comparing outcomes of 'SIP' versus 'no SIP or necrotising enterocolitis (NEC)' were included. DATA EXTRACTION Neurodevelopmental outcomes at ≥1 year corrected age were extracted as the main outcome measure. Data were pooled separately for adjusted and unadjusted ORs using the random-effects model. The evidence level was assessed using the GRADE (Grading of Recommendations, Assessments, Development and Evaluations) framework. RESULTS Eighteen cohort studies (13 606 infants) were included. Meta-analysis of unadjusted ORs showed that SIP was significantly associated with increased odds of mortality, cerebral palsy, composite outcome of death or disability, visual impairment and hearing impairment. However, pooling of adjusted ORs (aOR) found significant associations only for mortality (aOR (95% CI) 2.27 (2.07 to 2.49); I2: 0%; four studies (n=10 695)), severe disability (aOR (95% CI) 2.06 (1.38 to 3.08); I2: 0%; two studies (n=321)) and composite outcome of 'death or disability' (aOR (95% CI) 2.18 (1.55 to 3.06); I2: 0%; two studies (n=321)). The level of evidence was 'low' or 'very low'. LIMITATIONS Lack of information on aORs from many studies. CONCLUSIONS SIP in very preterm infants is associated with higher odds of mortality, severe disability, and death or disability.

Abstract
BACKGROUND Feeding intolerance (FI) is a common clinical problem in preterm infants often caused by some neonatal disorders and drugs, including antenatal exposure to magnesium sulfate (MgSO4 ). OBJECTIVE To evaluate the association between hypermagnesemia at birth and FI in preterm infants during the first 72 hours of life. METHOD This was a cohort study conducted with preterm infants < 34 weeks of gestation. Infants presenting at least two of the following signs were considered as having FI: vomiting, abdominal distension, the need for continuous intermittent feeding, and delayed meconium passage. Hypermagnesemia was characterized by umbilical serum magnesium levels >2.5 mEq/l. RESULTS 251 infants were evaluated. The median birth weight and gestational age were 1390 (IQR 1020 -1070) g and 31 (IQR 28-32) weeks, respectively. The FI rate was 17.5%. The exposure rate to MgSO4 was similar in the tolerant and intolerant groups (53.1% x 63.6%, p=0.204), but hypermagnesemia was more frequent in the FI group (40.9% x 24.2%, p= 0.024). The univariate analysis showed that infants with hypermagnesemia were two-fold more likely to present FI (OR 2.16 95% CI 1.09-4.26). In the multiple logistic regression analysis, we found that hypermagnesemia was independently associated with FI (OR 2.51 - 95% CI 1.06-5.91), as well as maternal diabetes mellitus (OR 2.56 95% CI 1.07 - 6.14), SNAPPE-II (OR 1.051 95% CI 1.025-1.078), and brain hemorrhage (OR 3.61 95% CI 1.31 - 9.91). CONCLUSION In addition to other factors, hypermagnesemia at birth was independently associated with early feeding intolerance in preterm infants. This article is protected by copyright.

Association of Co-Exposure of Antenatal Steroid and Prophylactic Indomethacin with Spontaneous Intestinal Perforation. J Pediatr 2021; 235:34-41.e1.

Abstract
OBJECTIVE To evaluate the association of a combined exposure to antenatal steroids and prophylactic indomethacin with the outcome of spontaneous intestinal perforation (SIP) among neonates born at <26 weeks of gestation or <750 g birth weight. STUDY DESIGN We conducted a retrospective study of preterm infants admitted to Canadian Neonatal Network units between 2010 and 2018. Infants were classified into 2 groups based on receipt of antenatal steroids; the latter subgrouped as recent (≤7 days before birth) or latent (>7 days before birth) exposures. The co-exposure was prophylactic indomethacin. The primary outcome was SIP. Multivariable logistic regression analysis was used to calculate aORs. RESULTS Among 4720 eligible infants, 4121 (87%) received antenatal steroids and 1045 (22.1%) received prophylactic indomethacin. Among infants exposed to antenatal steroids, those who received prophylactic indomethacin had higher odds of SIP (aOR 1.61, 95% CI 1.14-2.28) compared with no prophylactic indomethacin. Subgroup analyses revealed recent antenatal steroids exposure with prophylactic indomethacin had higher odds of SIP (aOR 1.67, 95% CI 1.15-2.43), but latent antenatal steroids exposure with prophylactic indomethacin did not (aOR 1.24, 95% CI 0.48-3.21), compared with the respective groups with no prophylactic indomethacin. Among those not exposed to antenatal steroids, mortality was lower among those who received prophylactic indomethacin (aOR 0.45, 95% CI 0.28-0.73) compared with no prophylactic indomethacin. CONCLUSIONS In preterm neonates of <26 weeks of gestation or birth weight <750 g, co-exposure of antenatal steroids and prophylactic indomethacin was associated with SIP, especially if antenatal steroids was received within 7 days before birth. Among those unexposed to antenatal steroids, prophylactic indomethacin was associated with lower odds of mortality.

Abstract
Postnatal ductal closure is stimulated by rising oxygen tension and withdrawal of vasodilatory mediators (prostaglandins, nitric oxide, adenosine) and by vasoconstrictors (endothelin-1, catecholamines, contractile prostanoids), ion channels, calcium flux, platelets, morphologic maturity, and a favorable genetic predisposition. A persistently patent ductus arteriosus (PDA) in preterm infants can have clinical consequences. Decreasing pulmonary vascular resistance, especially in extremely low gestational age newborns, increases left-to-right shunting through the ductus and increases pulmonary blood flow further, leading to interstitial pulmonary edema and volume load to the left heart. Potential consequences of left-to-right shunting via a hemodynamically significant patent ductus arteriosus (hsPDA) include increased risk for prolonged ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis or focal intestinal perforation, intraventricular hemorrhage, and death. In the last decade, there has been a trend toward less aggressive treatment of PDA in preterm infants. However, there is a subgroup of infants who will likely benefit from intervention, be it pharmacologic, interventional, or surgical: (1) prophylactic intravenous indomethacin in highly selected extremely low gestational age newborns with PDA (<26 + 0/7 weeks' gestation, <750 g birth weight), (2) early targeted therapy of PDA in selected preterm infants at particular high risk for PDA-associated complications, and (3) PDA ligation, catheter intervention, or oral paracetamol may be considered as rescue options for hsPDA closure. The impact of catheter-based closure of hsPDA on clinical outcomes should be determined in future prospective studies. Finally, we provide a novel treatment algorithm for PDA in preterm infants that integrates the several treatment modalities in a staged approach.

Role of Nutrition in Prevention of Neonatal Spontaneous Intestinal Perforation and Its Complications: A Systematic Review. Nutrients 2020; 12:nu12051347. [PMID: 32397283 PMCID: PMC7284579 DOI: 10.3390/nu12051347] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 04/27/2020] [Accepted: 04/28/2020] [Indexed: 12/24/2022] Open
Abstract
Background: Spontaneous intestinal perforation (SIP) is a devastating complication of prematurity, and extremely low birthweight (ELBW < 1000 g) infants born prior to 28 weeks are at highest risk. The role of nutrition and feeding practices in prevention and complications of SIP is unclear. The purpose of this review is to compile evidence to support early nutrition initiation in infants at risk for and after surgery for SIP. Methods: A search of PubMed, EMBASE and Medline was performed using relevant search terms according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Abstracts and full texts were reviewed by co-first authors. Studies with infants diagnosed with SIP that included information on nutrition/feeding practices prior to SIP and post-operatively were included. Primary outcome was time to first feed. Secondary outcomes were incidence of SIP, time to full enteral feeds, duration of parenteral nutrition, length of stay, neurodevelopmental outcomes and mortality. Results: Nineteen articles met inclusion criteria—nine studies included feeding/nutrition data prior to SIP and ten studies included data on post-operative nutrition. Two case series, one cohort study and sixteen historical control studies were included. Three studies showed reduced incidence of SIP with initiation of enteral nutrition in the first three days of life. Two studies showed reduced mortality and neurodevelopmental impairment in infants with early feeding. Conclusions: Available data suggest that early enteral nutrition in ELBW infants reduces incidence of SIP without increased mortality.

A single-dose indomethacin prophylaxis for reducing perinatal brain injury in extremely low birth weight infants: a non-inferiority analysis. J Perinatol 2019; 39:1462-1471. [PMID: 31570798 DOI: 10.1038/s41372-019-0509-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Revised: 08/01/2019] [Accepted: 08/15/2019] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To evaluate whether rates of perinatal brain injury among extremely low birth weight infants are comparable between two treatments: single-dose indomethacin prophylaxis (SGL-IP) (0.2 mg/kg, given once) vs. standard-dose indomethacin prophylaxis (STD-IP) (0.1 mg/kg/day, 3 days). METHODS In this retrospective study, the primary outcome was perinatal brain injury (neuro-imaging evidence of intraventricular hemorrhage or periventricular leukomalacia) or death before discharge. A non-inferior efficacy of an SGL-IP regimen compared with a STD-IP regimen was determined by calculating the adjusted difference in the risk of the primary outcome using a multivariable logistic regression model. A 10-percentage point non-inferiority margin was favored. RESULTS Prevalence rates of primary outcome were 41.7% in the SGL-IP group (n = 403) and 42.5% in the STD-IP group (n = 509) (adjusted risk difference: -1.2, 95% CI: -7.6 to +5.2, p = 0.71). CONCLUSION Use of a single prophylactic indomethacin dose was as effective as a standard regimen in preventing perinatal brain injury.

Abstract
INTRODUCTION Preterm birth is associated with increased mortality and morbidity. Tocolytic drugs, such as indomethacin, are often used to postpone preterm delivery. Indomethacin has been proven to be more effective than other tocolytic agents in terms of delaying birth but is often prescribed with caution because of its potential association with adverse neonatal outcomes. We aim to study the effects of antenatal indomethacin on neonatal outcomes after controlling for potential confounders, as compared to nifedipine and/or atosiban. METHODS In this cohort study, we performed a retrospective analysis of maternal and neonatal data. Women were included if they received indomethacin, nifedipine or atosiban as a tocolytic drug for imminent preterm labor and gave birth at a gestational age (GA) between 235/7 and 320/7 weeks, between 2010 and 2015. Main outcome measures were: neonatal death, necrotizing enterocolitis (NEC), spontaneous intestinal perforation (SIP), intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), patent ductus arteriosus (PDA) and its treatment. RESULTS Four hundred seventy-four women, delivering 610 infants were investigated. The incidence of the following adverse neonatal outcomes were significantly higher after indomethacin use: neonatal death (p = .017), NEC (p = .026), SIP (p = .008), PDA (p = .000) and PDA ligation (p = .000). However, these associations showed to be nonsignificant after adjusting for confounders (adjusted odds ratio neonatal mortality 1.6 (0.7-3.8)), NEC 1.6 (0.6-4.4), SIP 2.8 (0.3-30.0), PDA 1.1 (0.6-2.2) and PDA ligation 2.2 (0.7-6.5). CONCLUSIONS The presumed association between antenatal indomethacin exposure and several adverse neonatal outcomes may be based upon indication bias. Taking important confounding factors, such as GA at birth and neonatal birth weight into account, antenatal indomethacin exposure does not result in a higher incidence of adverse neonatal outcomes. However, there may be a higher risk for spontaneous intestinal perforation.

Abstract
OBJECTIVE To describe conservative management of spontaneous intestinal perforation (SIP) in preterm infants using peritoneal needle aspiration (PNA). STUDY DESIGN Monocentric retrospective review of SIP cases treated primarily by PNA between 1999 and 2015 (n=31). RESULTS Mean gestational age was 29.2±2.4 weeks and birthweight 1149±428 g. SIP occurred at 3.7±2.2 days of life. PNA achieved definitive treatment in 18 patients (60%) with a mean of 1.8 (±0.8) procedures. All patients requiring more than three PNAs had secondary laparotomy. Two patients died and five presented severe cerebral lesions. Full enteral feeding was achieved 42±18 days after SIP. Intestinal morbidity included cholestasis (n=6), intestinal stricture (n=1) and growth restriction (n=22). On follow-up (n=25, median=4 years), no severe impairment was noted. Seventeen children (68%) had a normal development. CONCLUSION PNA as primary therapy for SIP is a viable option, resulting in definitive treatment in 60% of cases, with limited mortality and morbidity.

Abstract
OBJECTIVES Patent ductus arteriosus (PDA) remains a challenging issue in very low birth weight (VLBW) infants, and its management varies widely. Our aim in this study was to document the natural course of ductus arteriosus in a cohort of VLBW infants who underwent conservative PDA management with no medical or surgical intervention. METHODS A retrospective cohort study conducted in 2 European level-3 neonatal units. RESULTS A total of 368 VLBW infants were born within the study period. Two hundred and ninety-seven infants were free of congenital malformations or heart defects and survived to hospital discharge. Out of those, 280 infants received truly conservative PDA management. In 237 (85%) of nontreated infants, the PDA closed before hospital discharge. The Kaplan-Meier model was used to document the incidence proportion of PDA closure over time for different gestational age groups. The median time to ductal closure was 71, 13, 8, and 6 days in <26+0, 26+0 to 27+6, 28+0 to 29+6, and ≥30 weeks, respectively. For different birth weight groups, the median was 48, 22, 9, and 8 days in infants weighing <750, 750 to 999, 1000 to 1249, and 1250 to 1500 g, respectively. No statistically significant relationship was found between PDA closure before hospital discharge and neonatal morbidities. CONCLUSIONS The likelihood of PDA spontaneous closure in VLBW infants is extremely high. We provide in our findings a platform for future placebo-controlled trials focused on the smallest and youngest infants.

Abstract
This study aimed to measure longitudinal quantities of the long chain fatty acids, their biologically active terminal metabolites and related intermediates (also called oxylipins) in preterm human milk expressed during the first month of lactation. In a prospective cohort, breast milk was collected throughout the first month of lactation in 30 women who delivered preterm infants. Eighteen bioactive lipids and their intermediates were quantified via solid phase extraction and LC-MS/MS. Analysis by GC-FID quantified the fatty acid precursors. Arachidonic acid (ARA) and docosahexaenoic acid (DHA) milk concentrations significantly declined throughout the first month. Oxylipin concentrations did not change during lactation. Positive associations existed between ARA and thromboxane B2, eicosapentaenoic acid and 18-hydroxyeicosapentaenoic acid, and between DHA and PDX and 14- and 17-hydroxydocosahexaenoic acids. DHA concentrations were 1.5 times higher and 14-HDHA was 1.7 times higher in milk from women taking DHA supplements. This investigation showed conditionally essential fatty acids, ARA and DHA, decreased in preterm milk, suggesting a need to supplement their intake for the breast milk-fed preterm infant. Positive associations between parent fatty acids, bioactive lipids and intermediates, as well as sensitivity of milk to maternal fatty acid intake, support consideration of a comprehensive approach to providing fatty acids for preterm infants through both maternal and infant supplementation.

Abstract
OBJECTIVE To determine the effect of concomitant administration of prophylactic indomethacin and early enteral feeds on the risk of spontaneous intestinal perforation (SIP) in extremely low-birth-weight (ELBW) infants, and to describe the variation in prophylactic indomethacin use in Canada. STUDY DESIGN A retrospective cohort study of 4268 ELBW infants born at <30 weeks' gestation admitted to Canadian neonatal units between 2010 and 2014 was conducted. Prophylactic indomethacin (I+ or I-, administered within 24 h) and early feeding (E+ or E-, initiated in the first 2 days) exposures were studied concurrently and independently. The primary outcomes were SIP and death before discharge. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. RESULTS Compared with the I-/E+ reference group (n=1829), infants in I+/E+ (n=285; aOR 2.92, 95% CI 1.41 to 6.08) and I+/E- (n=213; aOR 2.84, 95% CI 1.35 to 5.98) groups had higher odds of SIP, whereas those in the I-/E- group had similar odds (n=1941; aOR 1.37, 95% CI 0.88 to 2.14). Odds of SIP were higher in the indomethacin exposed group (I+) compared with the unexposed (I-) group when controlled for early feeding (aOR 2.43, 95% CI 1.41 to 4.19), but not in the early feeding group when controlled for indomethacin. The use of prophylactic indomethacin ranged from 0% usage in 13 sites to 78% use in one site. CONCLUSION Prophylactic indomethacin was associated with increased odds of SIP independently from early feeding in this cohort; however, early enteral feeding was not associated with SIP. Marked variation in the use of prophylactic indomethacin was identified.

Abstract
Parenteral nutrition (PN) represents one of the most notable achievements of modern medicine, serving as a therapeutic modality for all age groups across the healthcare continuum. PN offers a life-sustaining option when intestinal failure prevents adequate oral or enteral nutrition. However, providing nutrients by vein is an expensive form of nutrition support, and serious adverse events can occur. In an effort to provide clinical guidance regarding PN therapy, the Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) convened a task force to develop consensus recommendations regarding appropriate PN use. The recommendations contained in this document aim to delineate appropriate PN use and promote clinical benefits while minimizing the risks associated with the therapy. These consensus recommendations build on previous ASPEN clinical guidelines and consensus recommendations for PN safety. They are intended to guide evidence-based decisions regarding appropriate PN use for organizations and individual professionals, including physicians, nurses, dietitians, pharmacists, and other clinicians involved in providing PN. They not only support decisions related to initiating and managing PN but also serve as a guide for developing quality monitoring tools for PN and for identifying areas for further research. Finally, the recommendations contained within the document are also designed to inform decisions made by additional stakeholders, such as policy makers and third-party payers, by providing current perspectives regarding the use of PN in a variety of healthcare settings.

Abstract
OBJECTIVE To compare demographic data, prenatal and postnatal characteristics, laboratory data, and outcomes in a cohort of premature infants with spontaneous ileal perforation (SIP), surgical necrotizing enterocolitis (sNEC) and matched controls. METHODS A retrospective case-control study of infants with intestinal perforation with a birth weight (BW) less than 2,000 grams and gestational age (GA) less than 34 weeks and infants without perforation matched for BW (±150 grams) and GA (±1week). RESULTS 130 premature infants were included, 30 infants with SIP, 35 infants with sNEC and 65 control infants. The median age of onset was 5 days postnatal age in SIP versus 25 days in sNEC (p < 0.001) and the peak onset was at 26 weeks corrected GA for SIP and 30 weeks corrected GA for sNEC. Infants with perforation had significantly higher rates of mortality (p < 0.001) and common morbidities associated with prematurity. Administration of corticosteroids and indomethacin did not differ among groups. SIP was more common among infants born to young mothers (p = 0.04) and less common in infants receiving caffeine (p = 0.02). sNEC was less common among infants receiving early red cell transfusion (p = 0.01). Perforation and sNEC trended towards less common in infants receiving inhaled nitric oxide. CONCLUSION SIP and sNEC are distinct clinical entities. Potential protective effects of caffeine, inhaled nitric oxide, and early transfusion should be further studied.

Abstract
OBJECTIVE To examine circulating levels of inter-alpha inhibitor protein (IaIp) in infants with necrotizing enterocolitis (NEC), spontaneous intestinal perforation (SIP), and matched controls to assess the diagnostic accuracy of IaIp to differentiate NEC from SIP and to compare receiver operating characteristics of IaIp for NEC with C-reactive protein (CRP). STUDY DESIGN A prospective, nested case-control study of infants with feeding intolerance was carried out. Blood and clinical data were collected from 27 infants diagnosed with NEC or SIP and from 26 matched controls admitted to our unit. Infants with modified Bell criteria stage 2 or greater were included as NEC. Clinical, radiologic, and/or surgical findings were used to identify infants with SIP. Controls were matched for gestational age, postnatal age, sex, and birth weight. RESULTS Mean ± SD IaIp blood levels were 147 ± 38 mg/L, 276 ± 67 mg/L, and 330 ± 100 mg/L in infants with NEC, SIP, and matched controls, respectively (P < .004 and P < .01). Receiver operating characteristics analysis to establish the predictive value of NEC demonstrated areas under curve of 0.98 and 0.63 for IaIp and CRP, respectively. CONCLUSIONS IaIp levels were significantly decreased in infants with NEC compared with SIP and matched controls. The diagnostic accuracy of IaIp for NEC was superior to that of CRP.

Abstract
OBJECTIVE Enteral feeds are often discontinued or reduced during indomethacin treatment for patent ductus arteriosus (PDA) in preterm neonates, but the clinical impact of this practice is unknown. The objective of this study was to study the associations between enteral feed volume at the time of indomethacin therapy in preterm neonates with PDA and subsequent gastrointestinal outcomes. STUDY DESIGN Retrospective cohort study. Single-center level III Neonatal Intensive Care Unit. RESULTS All consecutive preterm neonates who had received treatment with indomethacin for PDA over a 5-year period were included and categorized based on enteral feed volume exposure during treatment (Group A: nil per oral (NPO, N=229); Group B: ⩽60 ml kg(-1) day(-1) (N=142); Group C:>60 ml kg(-1) day(-1) (N=44)). Baseline characteristics and clinical outcomes were compared between the three groups. The primary outcome was necrotizing enterocolitis (NEC) ⩾stage IIa, while secondary outcomes included other gastrointestinal complications and common prematurity-related morbidities. Group C had a higher gestational age (mean±s.d.; A: 26.3±1.8; B: 26.1±1.8; C: 27.0±2.0 weeks), birth weight (A: 864±239; B: 847±202; C: 932±234 g) and postnatal age at the time of indomethacin treatment (A: 5.3±2.9; B: 7.2±4.9; C: 15.4±6.6 days). All groups had similar rates of the primary outcome NEC (A: 6.1%, B: 7.8% and C: 4.6%, respectively). They also had similar rates of the secondary outcomes with the exception of days to reach enteral feeds of 120 ml kg(-1) day(-1) (A: 22.8±8.5; B: 20.5±8.6; C: 16.8±7.7; P<0.05 for all inter-group comparisons). Secondary analysis including only those neonates who were not already NPO before indomethacin treatment (N=261) and categorized based on preemptive management (made NPO; enteral feed volume reduced; enteral feed volume unchanged/increased) also showed similar results. CONCLUSIONS This large retrospective study did not identify any association between enteral feed volumes during indomethacin treatment or preemptive reduction in enteral feeds and subsequent incidence of adverse gastrointestinal outcomes in preterm neonates. Preemptive reduction in enteral feed volume was associated with longer time to reach full enteral feeds.

Abstract
BACKGROUND Maternal obesity is associated with increased systemic inflammation and an increased risk of preterm premature rupture of membranes. There is an established association between an inflammatory intrauterine environment and adverse neonatal outcomes that is independent of gestational age and mediated by the fetal inflammatory response. It is unknown whether the maternal systemic inflammation that is present in obese women influences the intrauterine environment and predisposes the fetus to adverse neonatal outcomes after preterm premature rupture of membranes. OBJECTIVE The purpose of this study was to determine whether maternal obesity is associated with adverse neonatal outcomes in pregnancies that are complicated by preterm premature rupture of membranes. STUDY DESIGN This was a secondary analysis of the Maternal-Fetal Medicine Units Network Randomized Clinical Trial on the Beneficial Effects of Antenatal Magnesium Sulfate. Women with singleton pregnancies that were affected by preterm premature rupture of membranes who delivered live-born infants between 24 + 0 and 33 + 6 weeks of gestation were included. An adverse neonatal outcome was defined as a composite outcome of neonatal death, severe necrotizing enterocolitis, respiratory distress syndrome, sepsis, or severe intraventricular hemorrhage. The rates of the composite outcome were compared between obese (body mass index, ≥30 kg/m(2)) and nonobese women. Multivariable logistic regression was used to evaluate the independent effect of obesity on neonatal outcomes. Magnesium sulfate administration, steroid administration, maternal diabetes mellitus, gestational age at delivery, indomethacin exposure, birthweight, and chorioamnionitis were all considered as possible covariates in the multivariable regression models. RESULTS Three hundred twenty-five of the 1288 women (25.2%) who were included were obese, and 202 of these women (62.2%) had neonates with adverse outcomes. In univariable analysis, maternal prepregnancy obesity was associated with increased odds of an adverse neonatal outcome (odds ratio, 0.30, 95% confidence interval, 1.00-1.68). However, in our multivariable logistic regression model, gestational age at delivery (odds ratio, 0.93, 95% confidence interval, 0.92-0.94 per day), but not maternal obesity (odds ratio, 1.02, 95% confidence interval, 0.75-1.38), was associated with adverse neonatal outcomes. Obese African American women experienced preterm premature rupture of membranes (189 vs 196 days; p < .001) and delivery (199 vs 205 days; p < .001) earlier than nonobese African American women. This difference was not seen in non-African American women. CONCLUSIONS Maternal obesity was not associated independently with adverse neonatal outcomes in pregnancies that were affected by preterm premature rupture of membranes after adjustment for gestational age at birth. However, obese African American women rupture and deliver earlier than other women, which causes increased neonatal morbidity.

Abstract
OBJECTIVE To test the association between medical or surgical necrotizing enterocolitis (NEC) and caffeine administration in premature infants. STUDY DESIGN This single-center, retrospective study evaluated patients admitted to a level 3 neonatal intensive care unit (NICU) over an 18-month period. All patients were evaluated for factors associated with the development of NEC including exposure to caffeine (dosing and duration), gestational age, birth weight, vasoactive medications and maternal illicit drug use. RESULTS There were 615 subjects included in the study; among these subjects, 7.3% (n = 45) developed NEC (35 subjects receiving caffeine and 10 subjects not receiving caffeine). The administration of caffeine (p = 0.008), birth weight (p = 0.014) and the use of vasopressors (p = 0.033) were associated with the development of NEC. When considering only infants with a birth weight less than 1500 g and less than 32 weeks gestation, the effects of caffeine and vasopressor use remained statistically significant (p = 0.047 and p = 0.045, respectively). The time to development of NEC did not differ statistically between patients receiving caffeine and those not receiving caffeine (p = 0.129). CONCLUSION A potential association between the administration of caffeine and the development of medical or surgical necrotizing enterocolitis in premature infants exists. Further investigation of dose-dependent effects and loading doses is warranted.
