Abstract
BACKGROUND Radiographic diagnosis of necrotizing enterocolitis (NEC) is challenging. Deep learning models may improve accuracy by recognizing subtle imaging patterns. We hypothesized it would perform with comparable accuracy to that of senior surgical residents. METHODS This cohort study compiled 494 anteroposterior neonatal abdominal radiographs (214 images NEC, 280 other) and randomly divided them into training, validation, and test sets. Transfer learning was utilized to fine-tune a ResNet-50 deep convolutional neural network (DCNN) pre-trained on ImageNet. Gradient-weighted Class Activation Mapping (Grad-CAM) heatmaps visualized image regions of greatest relevance to the pretrained neural network. Senior surgery residents at a single institution examined the test set. Resident and DCNN ability to identify pneumatosis on radiographic images were measured via area under the receiver operating curves (AUROC) and compared using DeLong's method. RESULTS The pretrained neural network achieved AUROC of 0.918 (95% CI, 0.837-0.978) with an accuracy of 87.8% with five false negative and one false positive prediction. Heatmaps confirmed appropriate image region emphasis by the pretrained neural network. Senior surgical residents had a median area under the receiver operating curve of 0.896, ranging from 0.778 (95% CI 0.615-0.941) to 0.991 (95% CI 0.971-0.999) with zero to five false negatives and one to eleven false positive predictions. The deep convolutional neural network performed comparably to each surgical resident's performance (p > 0.05 for all comparisons). CONCLUSIONS A deep convolutional neural network trained to recognize pneumatosis can quickly and accurately assist clinicians in promptly identifying NEC in clinical practice. LEVEL OF EVIDENCE III (study type: Study of Diagnostic Test, study of nonconsecutive patients without a universally applied "gold standard").

Abstract
Surgically treated necrotising enterocolitis (sNEC) is associated with significantly worse neurodevelopmental outcomes than that seen in premature infants without NEC. We aim to review the association between factors involved in the surgical treatment of NEC and subsequent neurodevelopmental outcomes to identify potential areas for improvement. The PubMed and Embase databases were interrogated for articles reporting neurodevelopmental outcomes in babies treated surgically for NEC using key terms including: "Infant", "Necrotising enterocolitis", "Surgical", "Neurodevelopmental" and "Outcomes". The search strategy yielded 1170 articles and after applying inclusion and exclusion criteria 22 studies remained and formed the review. A diverse range of neurodevelopmental outcomes were reported. Extreme prematurity and lower birth weight were associated with worse neurodevelopmental outcomes. The use of peritoneal drains and enterostomies were associated with worse outcomes. Modifications to surgical strategies in NEC may improve neurodevelopmental outcomes but the effect of confounding factors remains unclear. Further large scale studies are required to define the optimum strategies for treating NEC surgically and to develop a core outcome set for research into NEC.

Abstract
OBJECTIVE Assess mortality and neurodevelopmental outcomes at 2 years of corrected age in children who participated in the PlaNeT-2/MATISSE (Platelets for Neonatal Transfusion - 2/Management of Thrombocytopenia in Special Subgroup) study, which reported that a higher platelet transfusion threshold was associated with significantly increased mortality or major bleeding compared to a lower one. DESIGN Randomised clinical trial, enrolling from June 2011 to August 2017. Follow-up was complete by January 2020. Caregivers were not blinded; however, outcome assessors were blinded to treatment group. SETTING 43 level II/III/IV neonatal intensive care units (NICUs) across UK, Netherlands and Ireland. PATIENTS 660 infants born at less than 34 weeks' gestation with platelet counts less than 50×109/L. INTERVENTIONS Infants were randomised to undergo a platelet transfusion at platelet count thresholds of 50×109/L (higher threshold group) or 25×109/L (lower threshold group). MAIN OUTCOMES MEASURES Our prespecified long-term follow-up outcome was a composite of death or neurodevelopmental impairment (developmental delay, cerebral palsy, seizure disorder, profound hearing or vision loss) at 2 years of corrected age. RESULTS Follow-up data were available for 601 of 653 (92%) eligible participants. Of the 296 infants assigned to the higher threshold group, 147 (50%) died or survived with neurodevelopmental impairment, as compared with 120 (39%) of 305 infants assigned to the lower threshold group (OR 1.54, 95% CI 1.09 to 2.17, p=0.017). CONCLUSIONS Infants randomised to a higher platelet transfusion threshold of 50×109/L compared with 25×109/L had a higher rate of death or significant neurodevelopmental impairment at a corrected age of 2 years. This further supports evidence of harm caused by high prophylactic platelet transfusion thresholds in preterm infants. TRIAL REGISTRATION NUMBER ISRCTN87736839.

Abstract
OBJECTIVES Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are complications in preterm infants associated with high morbidity, mortality, impaired growth, and neurodevelopmental (ND) outcomes. Few studies have reported growth or ND outcomes of infants born extremely preterm with NEC/SIP beyond early childhood. Here, we compared anthropometric and ND outcomes, at 10 and 15 years, for children with medical NEC, surgical NEC, SIP, and neither NEC nor SIP. METHODS Participants from the prospective longitudinal extremely low gestational age newborns study were evaluated at ages 10 and 15 years for anthropometrics, neurocognition, attention-deficit/hyperactivity disorder, epilepsy, and gross motor function. RESULTS At age 10 years, 889 children were followed-up (medical NEC = 138, surgical NEC = 33, SIP = 29, no NEC/SIP = 689), and 694 children were followed up-at 15 years. Children with medical NEC had similar weight, BMI, height, and head circumference compared with controls at both 10 and 15 years. At 15 years, children with surgical NEC had lower weight z-score (adjusted β: -0.75, 95% confidence interval [CI]: -1.25 to -0.25), lower BMI z-score (adjusted β: -0.55, 95% CI: -1.09 to -0.01), and lower height z-score (adjusted β: -0.65, 95% CI: -1.16 to -0.14). Children with SIP had lower weight and height z-scores at age 10 years when adjusted for sample attrition, but these differences were not significant when adjusted for confounders. We observed no differences in long-term ND outcomes. CONCLUSIONS Surgical NEC- and SIP-associated growth impairment may persist through late childhood. ND outcomes among school-aged children born extremely preterm with any NEC or SIP are no different from children without NEC/SIP.

Abstract
OBJECTIVES The aim of the study was to assess cognitive outcomes in children with intestinal failure (IF) and children at high risk of IF with conditions affecting the small intestine requiring parenteral nutrition. METHODS EMBASE, Cochrane, Web of Science, Google Scholar, MEDLINE, and PsycINFO were searched from inception to October 2020. Studies were included constituting original data on developmental quotient (DQ), intelligence quotient (IQ) and/or severe developmental delay/disability (SDD) rates assessed with standardized tests. We used appropriate standardized tools to extract data and assess study quality. We performed random effects meta-analyses to estimate pooled means of DQ/IQ and pooled SDD rates (general population mean for DQ/IQ: 100, for percentage with SDD: 1.8%) for 4 groups: IF, surgical necrotizing enterocolitis (NEC), abdominal wall defects (AWD), and midgut malformations (MM). Associations of patient characteristics with DQ/IQ were evaluated with meta-regressions. RESULTS Thirty studies met the inclusion criteria. The pooled mean DQ/IQ for IF, NEC, AWD, and MM were 86.8, 83.3, 96.6, and 99.5, respectively. The pooled SDD rates for IF, NEC, AWD and MM were 28.6%, 32.8%, 8.5%, and 3.7%, respectively. Meta-regressions indicated that lower gestational age, longer hospital stay, and higher number of surgeries but not parenteral nutrition duration, were associated with lower DQ/IQ. CONCLUSIONS Adverse developmental outcomes are common in children with IF and NEC, and to a much lesser extent in children with AWD and MM. It is important to monitor cognitive development in children with conditions affecting the small intestine and to explore avenues for prevention and remediation.

Abstract
Spontaneous intestinal perforation (SIP) and surgical necrotizing enterocolitis (NEC) are intestinal conditions requiring surgical intervention in preterm infants. We aimed to compare the head growth and neurodevelopment of preterm infants with SIP and surgical NEC. A retrospective single-center study was performed in preterm infants born at less than 32 weeks of gestation and who had undergone surgery for NEC or SIP. Data from the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) at 24 months of corrected age (CA) and the Korean Ages and Stages Questionnaire (K-ASQ) or Korean Developmental Screening Test (K-DST) at 36 months were collected. Among 82 eligible infants, 60 infants had surgical NEC, and 22 infants were diagnosed with SIP. Head growth was faster until CA 4 months in preterm infants with SIP than in those with surgical NEC. At 36 months, abnormal findings in the K-ASQ or K-DST were more prevalent in the NEC group than in the SIP group in the gross motor (48.2% vs. 0%, p = 0.015), fine motor (40.7% vs. 0%, p = 0.037), cognitive (55.6% vs. 12.5%, p = 0.047), and social domains (44.4% vs. 0%, p = 0.032). More studies evaluating the neurodevelopmental outcomes of preterm infants with surgical NEC and SIP are required.

Abstract
OBJECTIVE This study aimed to investigate growth among neonates with gastrointestinal disorders. STUDY DESIGN Inclusion criteria included neonates with gastroschisis, omphalocele, intestinal atresia, tracheoesophageal fistula, Hirschsprung's disease, malabsorption disorders, congenital diaphragmatic hernia, and imperforate anus born between 2010 and 2018. Anthropometrics were collected for the first 30 months, and a subgroup analysis was performed for gastroschisis infants. RESULTS In 61 subjects, 13% developed severe growth failure within the first month. One-, four-, and nine-month weight and length z-scores were less than birth weight in all infants (p < 0.05). In infants with gastroschisis, a similar pattern was observed for weight z-scores only (p < 0.05). From birth to 15 months, head circumference z-score increased over time in all infants (p = 0.001), while in gastroschisis infants, weight, length, and head circumference z-scores increased over time (p < 0.05). CONCLUSION In a cohort of infants with gastrointestinal disorders, growth failure was followed by catch-up growth.

Abstract
PURPOSE To evaluate gastrointestinal tract (GIT) perforations in very low birth weight infants and the effects on neurodevelopmental outcome. METHODS Between 2000 and 2017 all cases with GIT perforation were analyzed regarding causes, associated morbidities and neurodevelopmental outcome and compared with matched (gestational age, birth weight, gender, year of birth) by 1:2 controls. RESULTS The incidence of GIT perforation was 2.0% (n = 38/1878). Diagnoses associated with GIT were meconium obstruction of prematurity (MOP,n = 19/50%), spontaneous intestinal perforation (SIP, n = 7/18%), necrotizing enterocolitis (NEC, n = 6/16%), iatrogenic perforation (n = 3/8%), volvulus (n = 2/5%) and meconium ileus (n = 1/3%). The NEC-associated perforations occurred later compared to those associated with MOP and SIP (median 8 days and 6 days vs. 17 days, p = 0.001 and 0.023, respectively) and main localization was the terminal ileum (84%). Cases had higher rates of late onset sepsis (55% vs. 24%, p = 0.003), longer duration of mechanical ventilation (median 30 days vs 18 days, p = 0.013) and longer stays at the hospital (median 122 days vs 83 days, p < 0.001); mortality rates did not differ. The 2‑year neurodevelopment follow-up revealed no differences between groups (normal development 49% vs. 40%). CONCLUSION Despite increased morbidities preterm infants with GIT perforation did not have a higher mortality rate and groups did not differ regarding neurodevelopmental outcome at the corrected for prematurity age of 2 years.

Abstract
Perinatal and neonatal infection and associated inflammatory response may adversely affect brain development and lead to neurodevelopmental impairment. Factors that predict the risk of infection and subsequent adverse outcomes have been identified but substantial gaps remain in identifying mechanisms and interventions that can alter outcomes. This article describes the current epidemiology of neonatal sepsis, the pathogenesis of brain injury with sepsis, and the reported long-term neurodevelopment outcomes among survivors.

Abstract
PURPOSE To evaluate neurodevelopment and growth in extremely preterm infants with or without necrotizing enterocolitis or spontaneous intestinal perforation. METHODS We conducted a retrospective cohort study of infants admitted to Canadian neonatal intensive care units in 2010 to 2011. We assessed outcomes at 18 to 24 months' corrected ages for preterm infants <29 weeks of gestational age at birth with spontaneous intestinal perforation or non-perforated or perforated necrotizing enterocolitis, and for preterm infants with none of these gastrointestinal complications. The primary outcome was a composite of death or significant neurodevelopmental impairment at 18 to 24 months' corrected age. We used multivariable logistic regression models to adjust for gestational age, small for gestational age, prenatal steroids, cesarean section, multiple gestations, and SNAP-II score. RESULTS Of 2,019 infants total, 39 (1.9%) had spontaneous intestinal perforation, 61 (3%) had perforated necrotizing enterocolitis, and 115 (5.7%) had non-perforated necrotizing enterocolitis. Infants with spontaneous intestinal perforation (aOR 2.11; 95% CI 1.01-4.42), necrotizing enterocolitis (aOR 2.58; 95% CI 1.81-3.68), or any bowel perforation (aOR 3.97; CI 2.43-6.48) had higher odds of death or significant neurodevelopmental impairment compared to infants with none of these bowel diseases. CONCLUSIONS Spontaneous intestinal perforation, necrotizing enterocolitis, or any bowel perforation are risk factors for death or significant neurodevelopmental impairment in extremely preterm infants.

Abstract
BACKGROUND AND OBJECTIVES Preterm infants with necrotizing enterocolitis (NEC) are known to have worse neurodevelopmental outcomes, but there is no substantial evidence to support an underlying pathophysiology. We aimed to examine whether cerebral oxygenation differs in those infants who develop NEC compared to cerebral oxygenation in those who do not. METHODS We examined 48 infants <30 weeks' gestation admitted to a tertiary level NICU from October 2016 to May 2018. Infants with birth weight less than or equal to the second percentile, abnormal antenatal dopplers or twin-to-twin-transfusion-syndrome were excluded. Cerebral oximetry measurements were performed by using a near-infrared spectroscopy (NIRS) monitor weekly for 60 minutes, allowing measurement of cerebral tissue oxygenation index from the first week of life to 36 weeks postconceptional age. Weekly clinical status was also recorded. NEC was defined as greater than or equal to Bell stage 2. RESULTS The median birth weight was 884 g (range of 460-1600 g), the median weeks' gestational age was 26 + 3/7 (23 + 0/7 to 29 + 6/7), and 52% were girls. In total, 276 NIRS measurements were completed, and 7 infants developed NEC. NIRS measurements from 1 infant with NEC and 4 infants without NEC who developed hemorrhagic parenchymal infarcts were excluded from analysis. Infants who developed NEC had significantly lower cerebral tissue oxygenation index than those who did not (P = .011), even when adjusted for confounders, including gestational age, birth weight, patent ductus arteriosus, enteral feeds, sex, ethnicity, and hemoglobin. CONCLUSIONS Infants with NEC have significantly lower cerebral tissue oxygenation throughout their neonatal intensive care stay in comparison with those who did not develop NEC. This is a novel finding and could explain their worse neurodevelopmental outcome.

Abstract
PURPOSE No consensus guidelines exist for timing of enterostomy closure in neonatal isolated intestinal perforation (IIP). This study evaluated neonates with IIP closed during the initial admission (A1) versus a separate admission (A2) comparing total length of stay and total hospital cost. METHODS Using 2012 to 2017 Pediatric Health information System (PHIS) data, 359 neonates with IIP were identified who underwent enterostomy creation and enterostomy closure. Two hundred sixty-five neonates (A1) underwent enterostomy creation and enterostomy closure during the same admission. Ninety-four neonates (A2) underwent enterostomy creation at initial admission and enterostomy closure during subsequent admission. For the A2 neonates, total hospital length of stay was calculated as the sum of hospital days for both admissions. A1 neonates were matched to A2 neonates in a 1:1 ratio using propensity score matching. Multivariate models were used to compare the two matched pair groups for length of stay and cost comparisons. RESULTS Prior to matching, the basic demographics of our study population included a median birthweight of 960 g, mean gestational age of 29.5 weeks, and average age at admission of 4 days. Eighty-seven pairs of neonates with IIP were identified during the matching process. Neonates in A2 had 91% shorter total hospital length of stay compared to A1 neonates (HR: 1.91; 95% CI for HR: 1.44-2.53; p < .0001). The median length of stay for A1 was 95 days (95% CI: 78-102 days) versus A2 length of stay of 67 days (95% CI: 56-76 days). Adjusting for the same covariates, A2 neonates had a 22% reduction in the average total cost compared A1 neonates (RR: 0.78; 95% CI for RR: 0.64-0.95; p-value = 0.014). The average total costs were $245,742.28 for A2 neonates vs. $315,052.21 for A1 neonates (p < 0.001). CONCLUSION Neonates with IIP have a 28 day shorter hospital length of stay, $75,000 or 24% lower total hospital costs, and a 22 day shorter post-operative course following enterostomy closure when enterostomy creation and closure is performed on separate admissions. TYPE OF STUDY Prognosis Study. LEVEL OF EVIDENCE Level II.

Abstract
Almost half of all preterm births are caused or triggered by an inflammatory process at the feto-maternal interface resulting in preterm labor or rupture of membranes with or without chorioamnionitis (“first inflammatory hit”). Preterm babies have highly vulnerable body surfaces and immature organ systems. They are postnatally confronted with a drastically altered antigen exposure including hospital-specific microbes, artificial devices, drugs, nutritional antigens, and hypoxia or hyperoxia (“second inflammatory hit”). This is of particular importance to extremely preterm infants born before 28 weeks, as they have not experienced important “third-trimester” adaptation processes to tolerate maternal and self-antigens. Instead of a balanced adaptation to extrauterine life, the delicate co-regulation between immune defense mechanisms and immunosuppression (tolerance) to allow microbiome establishment is therefore often disturbed. Hence, preterm infants are predisposed to sepsis but also to several injurious conditions that can contribute to the onset or perpetuation of sustained inflammation (SI). This is a continuing challenge to clinicians involved in the care of preterm infants, as SI is regarded as a crucial mediator for mortality and the development of morbidities in preterm infants. This review will outline the (i) role of inflammation for short-term consequences of preterm birth and (ii) the effect of SI on organ development and long-term outcome.

Abstract
AIM To determine (1) the incidence of neurodevelopmental impairment (NDI) in necrotising enterocolitis (NEC), (2) the impact of NEC severity on NDI in these babies and (3) the cerebral lesions found in babies with NEC. METHODS Systematic review: three independent investigators searched for studies reporting infants with NDI and a history of NEC (PubMed, Medline, Cochrane Collaboration, Scopus). Meta-analysis: using RevMan V.5.3, we compared NDI incidence and type of cerebral lesions between NEC infants versus preterm infants and infants with medical vs surgical NEC. RESULTS Of 10 674 abstracts screened, 203 full-text articles were examined. In 31 studies (n=2403 infants with NEC), NDI incidence was 40% (IQR 28%-64%) and was higher in infants with surgically treated NEC (43%) compared with medically managed NEC (27%, p<0.00001). The most common NDI in NEC was cerebral palsy (18%). Cerebral lesions: intraventricular haemorrhage (IVH) was more common in NEC babies (26%) compared with preterm infants (18%; p<0.0001). There was no difference in IVH incidence between infants with surgical NEC (25%) and those treated medically (20%; p=0.4). The incidence of periventricular leukomalacia (PVL) was significantly increased in infants with NEC (11%) compared with preterm infants (5%; p<0.00001). CONCLUSIONS This study shows that a large proportion of NEC survivors has NDI. NEC babies are at higher risk of developing IVH and/or PVL than babies with prematurity alone. The degree of NDI seems to correlate to the severity of gut damage, with a worse status in infants with surgical NEC compared with those with medical NEC. TRIAL REGISTRATION NUMBER CRD42019120522.

Abstract
BACKGROUND Spontaneous intestinal perforation (SIP) is an intestinal complication that occurs in very ill preterms. We investigated whether SIP survivors have worse neurodevelopmental and gastrointestinal outcomes and a poorer quality of life than controls. METHODS A retrospective case-matched cohort study was performed involving infants treated for SIP in a NICU between August 1994 and April 2014. Controls and SIP patients were matched to gestational age, gender, and birth period. Medical records were reviewed. Telephone surveys were conducted to evaluate the medical condition, quality of life (PedsQL™ 4.0), neuropsychiatric and gastrointestinal outcome. McNemar's and Wilcoxon tests were performed, and generalized linear models were computed. RESULTS Forty-nine SIP patients were included. The percentages of children with multiple disabilities (40% vs. 17%, OR = 3.3) and requiring physiotherapy (86% vs. 60%, OR = 4.77) were higher in the SIP group than in the control group. Intraventricular hemorrhage (IVH) led to a worse neurodevelopmental outcome regardless of SIP (OR = 8.79 for disability), and female gender was a protective factor against disability (OR = 0.06). Reported quality of life and gastrointestinal comorbidities did not differ between the two groups. CONCLUSION SIP survivors tend to be at risk of multiple disabilities. IVH and female gender influence the neurodevelopmental outcome regardless of SIP. LEVELS OF EVIDENCE Level III: case-control study.

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
This state-of-the-art review article aims to highlight the most recent evidence about the therapeutic options of surgical necrotizing enterocolitis, focusing on the molecular basis of the gut-brain axis in relevance to the neurodevelopmental outcomes of primary peritoneal drainage and primary laparotomy. Current evidence favors primary laparotomy over primary peritoneal drainage as regards neurodevelopment in the surgical treatment of necrotizing enterocolitis. The added exposure to inhalational anesthesia in infants undergoing primary laparotomy is an additional confounding variable but requires further study. The concept of the gut-brain axis suggests that bowel injury initiates systemic inflammation potentially affecting the developing central nervous system. Signals about microbes in the gut are transduced to the brain and the limbic system via the enteric nervous system, autonomic nervous system, and hypothalamic-pituitary axis. Preterm infants with necrotizing enterocolitis have significant differences in the diversity of the microbiome compared with preterm controls. The gut bacterial flora changes remarkably prior to the onset of necrotizing enterocolitis with a predominance of pathogenic organisms. The type of initial surgical approach correlates with the length of functional gut and microbiome equilibrium influencing brain development and function through the gut-brain axis. Existing data favor patients who were treated with primary laparotomy over those who underwent primary peritoneal drainage in terms of neurodevelopmental outcomes. We propose that this is due to the sustained injurious effect of the remaining diseased and necrotic bowel on the developing newborn brain, in patients treated with primary peritoneal drainage, through the gut-brain axis and probably not due to the procedure itself.

Abstract
BACKGROUND The survival rate of infants and children with intestinal failure is increasing, necessitating a greater focus on their developmental trajectory. AIMS To evaluate neurodevelopmental outcomes in children with intestinal failure at 0-15months corrected age. STUDY DESIGN Analysis of clinical, demographic and developmental assessment results of 33 children followed in an intestinal rehabilitation program between 2011 and 2014. Outcome measures included: Prechtl's Assessment of General Movements, Movement Assessment of Infants, Alberta Infant Motor Scale and Mullen Scales of Early Learning. Clinical factors were correlated with poorer developmental outcomes at 12-15months corrected age. RESULTS Thirty-three infants (17 males), median gestational age 34weeks (interquartile range 29.5-36.0) with birth weight 1.98kg (interquartile range 1.17-2.50). Twenty-nine (88%) infants had abnormal General Movements. More than half had suspect or abnormal scores on the Alberta Infant Motor Scale and medium to high-risk scores for future neuromotor delay on the Movement Assessment of Infants. Delays were seen across all Mullen subscales, most notably in gross motor skills. Factors significantly associated with poorer outcomes at 12-15months included: prematurity, low birth weight, central nervous system co-morbidity, longer neonatal intensive care admission, necrotizing enterocolitis diagnosis, number of operations and conjugated hyperbilirubinemia. CONCLUSION Multiple risk factors contribute to early developmental delay in children with intestinal failure, highlighting the importance of close developmental follow-up.

Abstract
BACKGROUND White matter injury (WMI) is the most common form of brain injury in preterm infants. It could be induced by a systemic inflammatory response in preterm infants. OBJECTIVES We hypothesized that surgical necrotizing enterocolitis (surgNEC) results in more severe WMI than spontaneous intestinal perforation (SIP) on brain magnetic resonance imaging (MRI) at term-equivalent age (TEA). METHODS The medical records of 33 preterm infants born at less than 32 weeks of gestation who underwent surgery due to either NEC or SIP were reviewed retrospectively. White matter abnormality (WMA) on brain MRI was scored according to the diagnosis of surgNEC or SIP. RESULTS Nine patients were diagnosed with SIP and 24 with surgNEC. The median (range) gestational age of the SIP and surgNEC groups was 26+6 (23+3-27+6) and 25+5 weeks (23+3-31+2), respectively (p = 0.454). There were no differences in 1- and 5-min Apgar scores, mode of delivery, use of antenatal steroids, histologic chorioamnionitis, or incidence of respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) between the two groups. Males were more prevalent in the surgNEC group (75.0 vs. 33.3%, p = 0.044), and the incidence of sepsis was higher in the surgNEC group than in the SIP group (75.0 vs. 33.3%, p = 0.044). Multivariate regression showed that the difference in WMA scores between the two groups remained significant (estimated difference = 2.418; 95% CI 0.107-4.729). CONCLUSION In preterm infants at less than 32 weeks of gestation, those with surgNEC showed more severe WMI than infants with SIP on brain MRI at TEA.

BACKGROUND Intestinal perforation is known to correlate with neurodevelopmental outcome in very low-birthweight (VLBW) infants, and its two major causes are necrotizing enterocolitis (NEC) and focal intestinal perforation (FIP). Infants with FIP are reported to have better neurodevelopmental outcome than infants with NEC, but outcome has not been compared with that in infants without diseases that require surgery. The aim of this study was to compare neurodevelopmental outcomes between FIP survivors and infants without diseases that require surgery. METHODS Records of VLBW infants with FIP and infants without surgical diseases were retrospectively analyzed. Neurodevelopmental outcome was compared between eight infants with FIP and 24 case-matched control infants without surgical diseases using the Kyoto Scale of Psychological Development. Control group members were individually matched with FIP survivors for sex, gestational age, birthweight, and intraventricular hemorrhage (IVH) grade. Those with an episode of sepsis or severe IVH (grade 3-4) that occurred irrespective of FIP were excluded. RESULTS Three FIP survivors and 12 infants without surgical diseases were classified as neurodevelopmentally normal (37.5% vs 50%, P = 0.69) at a corrected age of 18 months-3 years. All neurodevelopmentally normal FIP survivors were born at a gestational age ≥ 26 weeks. CONCLUSION Excluding the influence of sepsis or severe IVH, no significant difference was found in neurodevelopmental outcome between FIP survivors and infants without surgical diseases. None of the FIP infants born before 26 weeks of gestation, however, had normal neurodevelopment, suggesting that longer gestation might be needed to overcome the stress associated with FIP.

Abstract
BACKGROUND Surgical intestinal disorders, such as necrotizing enterocolitis (NEC), focal intestinal perforation (FIP), and meconium-related ileus (MRI), are serious morbidities in very low-birthweight infants (VLBWI). The aim of this study was to compare the composite outcomes of death or neurodevelopmental impairment (NDI) in VLBWI with surgical intestinal disorders and assess independent risk factors for death and NDI at 18 months of corrected age. METHODS A retrospective matched-cohort study was conducted at 11 institutes. We included VLBWI who had undergone laparotomy for NEC, FIP, and MRI. Two control subjects were chosen for every surgical patient and matched for gestational age and birthweight to form the comparison group. Death and neurodevelopmental outcome at 18 months of corrected age were evaluated. RESULTS The number of infants in the NEC, FIP, MRI, and control groups was 44, 47, 42, and 261, respectively. In-hospital mortality was higher in infants with NEC and MRI relative to those in the control group (P < 0.001). The incidence rate for NDI at 18 months of corrected age was higher in infants with MRI relative to those in the control group (P = 0.021). On logistic regression analysis, low gestational age, male sex, small for gestational age, intraventricular hemorrhage, and MRI were associated with increased risk of death or NDI at 18 months of corrected age. CONCLUSIONS NEC and MRI were associated with in-hospital mortality, and MRI was associated with NDI or death at 18 months of corrected age.

Abstract
OBJECTIVE To determine if extremely low birth weight infants with surgical necrotizing enterocolitis have a higher risk of death or neurodevelopmental impairment and neurodevelopmental impairment among survivors (secondary outcome) at 18-22 months corrected age compared with infants with spontaneous intestinal perforation and infants without necrotizing enterocolitis or spontaneous intestinal perforation. STUDY DESIGN Retrospective analysis of the Neonatal Research Network very low birth weight registry, evaluating extremely low birth weight infants born between 2000 and 2005. The study infants were designated into three groups: (1) spontaneous intestinal perforation without necrotizing enterocolitis; (2) surgical necrotizing enterocolitis (Bell's stage III); and (3) neither spontaneous intestinal perforation nor necrotizing enterocolitis. Multivariate logistic regression analysis was performed to evaluate the association between the clinical group and death or neurodevelopmental impairment, controlling for multiple confounding factors including center. RESULT Infants with surgical necrotizing enterocolitis had the highest rate of death before hospital discharge (53.5%) and death or neurodevelopmental impairment (82.3%) compared with infants in the spontaneous intestinal perforation group (39.1 and 79.3%) and no necrotizing enterocolitis/no spontaneous intestinal perforation group (22.1 and 53.3%; P<0.001). Similar results were observed for neurodevelopmental impairment among survivors. On logistic regression analysis, both spontaneous intestinal perforation and surgical necrotizing enterocolitis were associated with increased risk of death or neurodevelopmental impairment (adjusted odds ratio 2.21, 95% confidence interval (CI): 1.5, 3.2 and adjusted OR 2.11, 95% CI: 1.5, 2.9, respectively) and neurodevelopmental impairment among survivors (adjusted OR 2.17, 95% CI: 1.4, 3.2 and adjusted OR 1.70, 95% CI: 1.2, 2.4, respectively). CONCLUSION Spontaneous intestinal perforation and surgical necrotizing enterocolitis are associated with a similar increase in the risk of death or neurodevelopmental impairment and neurodevelopmental impairment among extremely low birth weight survivors at 18-22 months corrected age.

Abstract
BACKGROUND Spontaneous intestinal perforation (SIP) is associated with the use of postnatal glucocorticoids and indometacin in extremely low birth weight (ELBW) infants. The authors hypothesised: 1) an association of SIP with the use of antenatal steroids (ANS) and indometacin either as prophylaxis for intraventricular hemorrhage (IVH) (P Indo) or for treatment of PDA (Indo/PDA) and 2) an increased risk of death or abnormal neurodevelopmental outcomes in infants with SIP at 18-22 months corrected age. DESIGN/METHODS The authors retrospectively identified ELBW infants with SIP in the Neonatal Research Network's generic database. Unadjusted analysis identified the differences in maternal, neonatal and clinical variables between infants with and without SIP. Logistic regression analysis identified the adjusted OR for SIP with reference to ANS, P Indo and Indo/PDA. Neurodevelopmental outcomes were assessed among survivors at 18-22 months corrected age. RESULTS Indo/PDA was associated with an increased risk of SIP (adjusted OR 1.61; 95% CI 1.25 to 2.08), while P Indo and ANS were not. SIP was independently associated with an increased risk of death or neurodevelopmental impairment (NDI) (adjusted OR 1.85; 95% CI 1.32 to 2.60) and NDI among survivors (adjusted OR 1.75, 95% CI 1.20 to 2.55). CONCLUSION Indometacin used for IVH prophylaxis and ANS were not associated with the occurrence of SIP in ELBW infants. Indometacin used for treatment of symptomatic PDA was however associated with an increased risk of SIP. ELBW infants with SIP have an increased risk of poor neurodevelopmental outcomes.

Abstract
OBJECTIVE We sought to determine the incidence of necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) in surviving extremely low-birth-weight (ELBW, <1000 g birth weight) infants and to establish the impact of NEC on outcomes by hospital discharge and at 18 to 22 months adjusted age in a large, contemporary, population-based practice. STUDY DESIGN Hospital outcome data for all ELBW infants born in the greater Cincinnati region from 1998 to 2009 were extracted from the National Institute of Child Health Neonatal Research Network Database. Neurodevelopmental outcome at 18 to 22 months was assessed using Bayley Scales of Infant Development-II scores for Mental Developmental Index and Psychomotor Developmental Index. Multivariable logistic regression was used and adjusted odds ratios reported to control for confounders. RESULT From 1998 to 2009, ELBW infants accounted for 0.5% of the 352 176 live-born infants in greater Cincinnati. The incidence of NEC was 12%, with a 50% case-fatality rate. Death before discharge, morbid complications of prematurity and neurodevelopmental impairment were all increased among infants diagnosed with NEC. Infants with surgical NEC and SIP had a higher incidence of death, but long-term neurodevelopmental outcomes were not different comparing surviving ELBW infants with medical NEC, surgical NEC and SIP. CONCLUSION Although ELBW infants comprise a very small proportion of live-born infants, those who develop NEC and SIP are at an increased risk for death, morbid complications of prematurity and neurodevelopmental impairment. No significant differences in neurodevelopmental outcomes were observed between the medical and surgical NEC and SIP groups.

Abstract
OBJECTIVES To examine the variation in the incidence and to identify the timing of the presentation of necrotizing enterocolitis (NEC) in a cohort of preterm infants within the Canadian Neonatal Network (CNN). METHODS This was a population-based cohort of 16 669 infants with gestational age (GA) <33 weeks, admitted to 25 NICUs participating in the CNN between January 1, 2003, and December 31(,) 2008. Variations in NEC incidence among the participating NICUs for the study period were examined. We categorized early-onset NEC as occurring at <14 days of age and late-onset NEC occurring at ≥14 days. Multivariate logistic regression analysis was performed to identify risk factors for early-onset NEC. RESULTS The overall incidence of NEC was 5.1%, with significant variation in the risk adjusted incidence among the participating NICUs in the CNN. Early-onset NEC occurred at a mean of 7 days compared with 32 days for late-onset NEC. Early-onset NEC infants had lower incidence of respiratory distress syndrome, patent ductus treated with indomethacin, less use of postnatal steroids, and shorter duration of ventilation days. Multivariate logistic regression analysis identified that greater GA and vaginal delivery were associated with increased risk of early-onset NEC. CONCLUSIONS Among infants <33 weeks' gestation, NEC appears to present at mean age of 7 days in more mature infants, whereas onset of NEC is delayed to 32 days of age in smaller, lower GA infants. Further studies are required to understand the etiology of this disease process.

Abstract
We aimed to determine motor, cognitive, and behavioral outcome at school age of children who had either necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP). This case-control study included infants with NEC Bell's stage IIA onward, infants with SIP, and matched controls (1996-2002). At school age, we assessed motor skills, intelligence, visual perception, visuomotor integration, verbal memory, attention, behavior, and executive functions. Of 93 infants with NEC or SIP, 28 (30%) died. We included 52 of 65 survivors for follow-up. At mean age of 9 y, we found that 68% of the children had borderline or abnormal scores on the Movement Assessment Battery for Children (versus 45% of controls). Their mean total intelligence quotient (IQ) was 86 ± 14 compared with 97 ± 9 in the controls. In addition, attention and visual perception were affected (p < 0.01 and p = 0.02). In comparison to controls, surgically treated children were at highest risk for adverse outcome. In conclusion, at school age, the motor functions and intelligence of many children with NEC or SIP were borderline or abnormal and, specifically, attention and visual perception were impaired. Children with NEC or SIP form a specific risk group for functional impairments at school age even though the majority does not have overt brain pathology.

Abstract
OBJECTIVE Our objective was to determine the obstetrical risk for spontaneous focal intestinal perforation (FIP) in very low birth weight (VLBW) infants. METHODS Eight mothers delivered infants who underwent laparotomy for FIP between 2001 and 2006 in our hospital. A retrospective case-control study of the eight case mothers and 32 control mothers was conducted. Clinical findings were retrospectively analyzed. RESULTS There were significant differences in the frequency of oligohydramnios (P<0.01) and velamentous cord insertion (P<0.05) between cases and controls. The 1-min Apgar score was significantly lower in the FIP group than in the control group (P<0.05). Moreover, primigravidity was significantly associated with a risk of FIP. CONCLUSIONS The etiology of FIP may be related to changes in the blood circulation, such as fetal hypoxic-ischemic episodes or disturbance in the umbilical blood flow, during the antepartum and/or intrapartum periods.

Abstract
UNLABELLED Necrotizing enterocolitis (NEC) is a serious condition with a high morbidity and mortality commonly affecting premature babies. Data for the impact of the long-term disease burden in developing countries are limited although poor long-term outcome of surgically managed patients has been shown in terms of increased risk of neurodevelopmental delay, increased infectious disease burden and abnormal neurological outcomes in the developed world. PURPOSE To evaluate the long-term outcome of a pre-human immunodeficiency virus pandemic NEC cohort to characterize common risk factors and outcome in a developing world setting. METHODS A retrospective review of medical records was carried out on a cohort of 128 premature neonates with surgical NEC (1992-1995). Morbidity, mortality and long-term outcome were evaluated. RESULTS Data for 119 of 128 sequentially managed neonates with surgically treated NEC was available. Mean gestational age was 32 weeks and average birth weight was 1,413 g. Early (30-day postoperative) survival was 69% (n = 82) overall and 71% in the <1,500 g birth weight group (n = 68; 53%). Overwhelming sepsis (n = 16) or pan-intestinal necrosis (n = 18) accounted for most of the early deaths. Late deaths (>30 days postoperatively, n = 22) resulted from short bowel syndrome (5), sepsis (9), intraventricular hemorrhage (1) and undetermined causes (7). On follow-up (mean follow-up 39 months, 30 for >2 years), long-term mortality increased to 50%. Late surgical complications included late colonic strictures (9), incisional hernias (2) and adhesive bowel obstruction (3). Fifteen patients had short bowel syndrome, of which 10 (66%) survived. Of the long-term survivors, 8 (20%) had severe neurological deficits and 20 (49%) had significant neurodevelopmental delay. Neurological deficits included severe auditory impairment [5 (12%)] and visual impairment [4 (10%)]. Recurrent infections and gastrointestinal tract complaints requiring hospital admission occurred in 16 (39%) of survivors. CONCLUSION Necrotizing enterocolitis in premature infants impacts morbidity and mortality considerably. A number do well in a developing country, but septic complications may be ongoing and recurrent. The high risk of neurodevelopmental and other problems continue beyond the neonatal period and patients should be "flagged" on for careful follow-up.

Abstract
OBJECTIVE To investigate if circulating cytokines are related to growth and neurodevelopmental outcome following necrotizing enterocolitis (NEC). STUDY DESIGN Pro-inflammatory cytokine levels were measured prospectively in 40 neonates and compared with neurodevelopmental outcome. Cytokine levels were measured at the onset of feeding intolerance (Group II, n = 17) or NEC (Group III, n = 10) and at weeks 2-3 in control infants (Group I, n = 13). Neurodevelopmental outcome was assessed at the age of 24-28 months. Data were analysed using descriptive statistics, non-parametric tests and Student t-test. RESULTS Median birth weights (range) in groups I, II and III were 1120 (525-1564) g, 1068 (650-1937) g and 1145 (670-2833) g, and median gestational ages (range) were 28 (24-35) weeks 28 (24-35) weeks and 28 (25-37) weeks respectively. NEC occurred in 10 infants. Serum IL-6 (interleukin-6) was elevated in group III, (p = 0.03). Significant developmental delay was found in 12% of the infants in Group II and 20% of the infants in Group III, but no infant in group I. Five infants in group III with NEC (50%), had head ultrasound abnormalities. At 1 year of age, growth, weight and head circumference were significantly different in Group III, however, at two years of age, only height was significantly different, p < 0.02. Although there was wide variation, neonatal cytokine levels tended to be greater in the infants later found to have abnormal cognitive and psychomotor outcomes. CONCLUSION This study suggests that increased serum levels of pro-inflammatory cytokines may play a role in the poor growth and neurodevelopment associated with this high-risk population.

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
So much is unknown about SIP-its etiology, pathophysiology, best treatment modality, and outcome. Yet the incidence of SIP is increasing as more VLBW infants are surviving and since SIP has been identified as a separate disease from NEC. Because many cases present with an insidious onset, it is imperative that practitioners review all x-rays with SIP in mind. Although SIP is a relatively rare occurrence in the NICU, its potential to increase morbidity and mortality in premature infants warrants further research to improve outcomes.

Abstract
In the last decade, it has become increasingly clear that necrotizing enterocolitis (NEC) is neither a uniform nor a well-defined disease entity. There are many factors that are forcing this unwelcome realization upon the neonatal and pediatric surgery communities. In the course of this manuscript we will review the history and the physical findings of the disparate etiologies of acquired neonatal intestinal diseases (ANIDs), some which do lead to the common final pathology of NEC and some which do not. New guidelines for distinguishing between ANIDs will also be suggested.

Abstract
Necrotizing enterocolitis (NEC) is one of the most common life-threatening gastrointestinal emergencies for the preterm infant. The survival rate for preterm infants after NEC has improved over the past two decades, but complications arising from medical and surgical intervention have produced many long term problems. Documented consequences of NEC include feeding intolerance and physical, developmental and cognitive problems. Bedside nurses are well positioned to detect early changes in the infant that may enable early treatment and reduce long-term complications.

Abstract
Background It is important to determine if rates of survival and major neurodevelopmental impairment in extremely low gestational age newborns (ELGANs; infants born at 23–27 weeks gestation) are changing over time. Methods Study infants were born at 23 to 27 weeks of gestation without congenital anomalies at a tertiary medical center between July 1, 1990 and June 30, 2000, to mothers residing in a thirteen-county region in North Carolina. Outcomes at one year adjusted age were compared for two epochs of birth: epoch 1, July 1, 1990 to June 30, 1995; epoch 2, July 1, 1995 to June 30, 2000. Major neurodevelopmental impairment was defined as cerebral palsy, Bayley Scales of Infant Development Mental Developmental Index more than two standard deviations below the mean, or blindness. Results Survival of ELGANs, as a percentage of live births, was 67% [95% confidence interval: (61, 72)] in epoch 1 and 71% (65, 75) in epoch 2. Major neurodevelopmental impairment was present in 20% (15, 27) of survivors in epoch 1 and 14% (10, 20) in epoch 2. When adjusted for gestational age, survival increased [odds ratio 1.5 (1.0, 2.2), p = .03] and major neurodevelopmental impairment decreased [odds ratio 0.54 (0.31, 0.93), p = .02] from epoch 1 to epoch 2. Conclusion The probability of survival increased while that of major neurodevelopmental impairment decreased during the 1990's in this regionally based sample of ELGANs.

Abstract
OBJECTIVES (1) To characterise neurodevelopmental outcome of neonates with necrotizing enterocolitis (NEC); (2) to define whether NEC increases risk of neurodevelopmental impairment in very low birth weight neonates; (3) to investigate whether stage of disease or need for surgery increase risk of poor outcome. DESIGN A systematic review was performed. Searches identified 182 relevant papers. Ten studies compared extremely low birthweight neonates with NEC to infants of similar age and gestation who did not develop NEC. Data are reported as OR (95% CIs, p values for test for overall effect) and compared by chi2. RESULTS 7843 children (821 with NEC) were included in the meta-analysis. Median follow-up was 20 months (range 12 to 156). Overall, 45% of children who had neonatal NEC were neurodevelopmentally impaired. Infants with NEC were significantly more likely than infants of similar age and gestation who did not develop NEC to be neurodevelopmentally impaired (1.6 (1.3 to 2.0), p = 0.0001) including a higher risk of cerebral palsy (1.5 (1.2 to 2.0), p = 0.001), visual (2.3 (1.0 to 5.1), p = 0.04), cognitive (1.7 (1.4 to 2.2), p<0.0001) and psychomotor impairment (1.7 (1.3 to 2.2), p<0.0001). The odds ratio of neurodevelopmental impairment was also 2.3 times higher in neonates with Bell's stage III disease or requiring surgery ((1.5 to 3.6), p = 0.0001). CONCLUSIONS NEC is associated with significantly worse neurodevelopmental outcome than prematurity alone. Presence of advanced NEC and need for surgery increase the risk of neurological impairment.

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.

Abstract
PURPOSE OF REVIEW The relationship between infection, the inflammatory response and adverse neurodevelopmental outcome in preterm infants is slowly being elucidated. The developing brain, particularly the periventricular white matter, is vulnerable to cytotoxic and hypoxic/ischemic injury, which places these infants at increased risk for abnormal cognitive and motor functioning. This review summarizes current data evaluating associations between infection and neurodevelopmental outcome in the preterm infant. RECENT FINDINGS Preterm infants are at risk for intrauterine and postnatal infections. Recent studies have linked infection/inflammation associated with chorioamnionitis, sepsis and necrotizing enterocolitis with adverse neurodevelopmental outcome and impaired growth in preterm infants. Investigators have also shown associations between infection and brain injury, including severe intraventricular hemorrhage and periventricular leukomalacia. Very-low-birth-weight preterm infants are at substantial risk for neonatal infection, with associated morbidity and mortality. It is postulated that exposure of the preterm brain to inflammatory mediators during infectious episodes contributes to brain injury and poor developmental outcome. SUMMARY Enhanced understanding of the interaction of infection, inflammation and brain injury will be critical to developing strategies to improve neurodevelopmental outcome in preterm infants.
