[PMID: 33172872 DOI: 10.1136/archdischild-2020-319057] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 09/12/2020] [Accepted: 10/17/2020] [Indexed: 01/18/2023]
Abstract
BACKGROUND Frequent and severe gastrointestinal disturbances have been reported with the use of diazoxide in adults and older children. However, no studies have investigated the incidence of necrotising enterocolitis (NEC) in diazoxide-exposed newborns. OBJECTIVE To evaluate a possible association between diazoxide treatment for neonatal hypoglycaemia and the occurrence of NEC. DESIGN Multicentre retrospective cohort study. SETTING Three tertiary neonatal intensive care units in Toronto, Canada. PATIENTS All patients treated with diazoxide for persistent hypoglycaemia between July 2012 and June 2017 were included. Overall incidence of NEC during those years on the participating units was obtained for comparison from the Canadian Neonatal Network database. MAIN OUTCOME Incidence of NEC after diazoxide exposure. RESULTS Fifty-five neonates were exposed to diazoxide during the study period. Eighteen patients (33%) showed signs of feeding intolerance, and 7 developed NEC (13%). A diagnosis of NEC was more prevalent in the diazoxide-exposed, as compared with non-exposed infants of similar gestational age (OR 5.07, 95% CI 2.27 to 11.27; p<0.001), and greatest among infants born at 33-36 weeks' gestation (OR 13.76, 95% CI 3.77 to 50.23; p<0.001). All but one of the neonates diagnosed with NEC developed the disease within 7 days from initiation of diazoxide treatment. CONCLUSION The present data suggest a possible association between diazoxide exposure and the development of NEC in neonates. Further evaluation of the diazoxide-associated risk of NEC in neonates treated for persistent hypoglycaemia is warranted.

Abstract
BACKGROUND AND AIMS Ampicillin is 1 of the most commonly used antibiotics for treatment of early onset sepsis, but its pharmacokinetics (PK) is poorly characterized. We aimed to define the dose of ampicillin for late preterm and term neonates by evaluating its PK in serum, cerebrospinal (CSF), and epithelial lining fluid. METHODS A prospective study included neonates receiving ampicillin for suspected or proven early onset sepsis and pneumonia. PK samples were collected at steady state, at predose and 5 minutes, 1 hour, 3 hours, 8 hours, and 12 hours after ampicillin 3-minute infusion. Ampicillin concentrations were measured by ultra-high-performance liquid chromatography. Noncompartmental anaysis (NCA) and population pharmacokinetic (pop-PK) modeling were performed and probability of therapeutic target attainment was simulated. RESULTS In 14 neonates (GA of 32-42 wks; mean BW 2873 g), PK parameters (mean ± SD) in NCA were the following: half-life 7.21 ± 7.97 hours; volume of distribution (Vd) 1.07 ± 0.51 L; clearance (CL) 0.20 ± 0.13 L/h; 24-hour area under the concentration-time curve 348.92 ± 114.86 mg*h/L. In pop-PK analysis, a 2-compartmental model described the data most adequately with the final parameter estimates of CL 15.15 (CV 40.47%) L/h/70kg; central Vd 24.87 (CV 37.91%) L/70kg; intercompartmental CL 0.39 (CV 868.56) L/h and peripheral Vd 1.039 (CV 69.32%) L. Peutic target attainment simulations demonstrated that a dosage of 50 mg/kg q 12 hours attained 100% fT > MIC 0.25 mg/L, group B streptococcal breakpoint. CONCLUSIONS We recommend ampicillin dosage 50 mg/kg q 12 hours for neonates with gestational age ≥32 weeks during the first week of life.

Abstract
OBJECTIVES To study the clinical profile, complications, antibiotic resistance pattern, treatment, and outcome of out-born neonates with Acinetobacter spp. sepsis admitted in Pediatric emergency of a tertiary care hospital in North India. METHODS In this subgroup analysis of a prospective study (conducted over 1 y, February 2018 through January 2019), neonates with Acinetobacter spp. sepsis were included. The data collection included demographic details, clinical features, pre-referral treatment, complications, antibiotic resistance pattern, treatment, and final outcome. RESULTS Acinetobacter spp. accounted for 10.6% (43/406) of all isolates and 22.7% (43/189) of Gram-negative isolates. The median (IQR) age at presentation was 1 (1-2) d, 2/3rd were male, and 46.5% were preterm. All were admitted in peripheral hospitals before referral to authors' centre and all received intravenous antibiotics and fluids. The resistance to different antibiotics was: Ciprofloxacin 82%, cephalosporins 78-100%, amikacin 75%, pipercillin-tazobactum 62%, carbapenems 50-85%, chloramphenicol 83%, and tetracycline 50-60%. All isolates were sensitive to colistin. The survival rate was 37.2% (n = 16) and 62.8% (n = 27) had poor outcome [death and Left against medical advice (LAMA)]. Higher proportion of neonates with Acinetobacter sepsis had septic shock, multi-organ dysfunctional syndrome (MODS), and disseminated intravascular coagulation (DIC); and higher proportion required mechanical ventilation, vasoactive drugs, and had poor outcome compared to those with sepsis due to other organisms. CONCLUSIONS Acinetobacter spp. accounts for high burden of sepsis among out-born neonates and is associated with alarmingly high resistance to cephalosporins, fluroquinolones, aminoglycosides, pipercillin-tazobactum, tetracyclines, and carbapenems. Neonates with Acinetobacter spp. sepsis had higher rates of complications, requirement of mechanical ventilation and vasoactive drugs, and poor survival.

Abstract
BACKGROUND Immature gut motility in preterm neonates may be a risk factor for necrotizing enterocolitis (NEC). Using preterm pigs as a model for infants, we hypothesized that intestinal dysmotility precedes NEC development. METHODS Eighty-five preterm pigs were fed increasing amounts of milk diets to induce NEC lesions, as detected at autopsy on day 5. Gut transit time was determined on day 4 by x-ray imaging after oral intake of contrast solution. RESULTS No clinical or radiological signs of NEC were detected on day 4, but macroscopic NEC lesions were recorded in 59% of pigs (n = 50) on day 5. Relative to pigs without NEC (noNEC, n = 35), pigs with small intestinal lesions (siNEC, n = 18) showed delayed stomach emptying time (StEmpty) and time for contrast to reach cecum (ToCecum) already on day 4. Pigs with lesions only in colon (coNEC, n = 20) showed more diarrhea, shorter ToCecum time, but longer small intestinal emptying time (SiEmpty). ToCecum time predicted siNEC and coNEC lesions with a receiver-operator characteristic area under the curve of 78-81%. CONCLUSIONS Region-dependent changes in gut transit time is associated with early NEC development in preterm pigs. How gut dysmotility is related to NEC in preterm infants requires further investigations. IMPACT Using preterm pigs as a model for preterm infants, we show that gut transit time, using serial x-ray contrast imaging, was changed in individuals with NEC-like lesions before they showed the typical radiological signs of NEC. Thus prolonged transit time across the entire gut was recorded when NEC lesions appeared in the small intestine but not when lesions were detected only in the colon. Until now, recordings of food transit have mainly investigated changes in the upper gut. Using serial x-rays, this study describes food transit across the entire gut and documents a region-dependent effect of NEC lesions on gut transit changes in preterm individuals. The findings provide proof of concept for use of x-ray contrast imaging as a tool to monitor gut transit in preterm pigs as models for infants. Delayed passage across the entire gut may be an early sign of small intestinal NEC, at least in pigs. More studies are needed to confirm relations in infants. In the future, it might be possible to use x-ray contrast imaging in preterm infants to better understand gut motility in relation to early NEC progression and need for medical NEC treatment.

Abstract
The vitamin D receptor (VDR), coded by the VDR gene, plays a pivotal role in executing cellular functions when bound by the active form of vitamin D. Gene polymorphisms in this receptor have been increasingly associated with a heightened state of vulnerability to certain diseases. However, limited data is available concerning the role of VDR gene polymorphisms in preterm infant complications. In 114 premature infants (< 32 weeks gestation) we analyze four single nucleotide VDR polymorphisms (rs2228570 (FokI), rs1544410 (BsmI), rs797532 (ApaI), rs731236 (TaqI)) for their association with respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC) and retinopathy of prematurity (ROP). The results show that BPD was almost four times more likely in infants with the genotype CC of ApaI (rs7975232) (OR 3.845; p = 0.038). While both BPD and NEC were 2.1 times more likely to occur in preterm infants with the allele C of ApaI (rs7975232) (respectively: OR 2.111 and OR 2.129, p < 0.05). The ApaI VDR polymorphism appears to influence incidence of BPD and NEC in preterm infants. Considering VDR polymorphisms in future genetic investigations, in preterm complications, may prove clinically relevant.

Abstract
This paper reviews common advertising claims by egg freezing companies and evaluates the medical evidence behind those claims. It then surveys legal standards for truth in advertising, including FTC and FDA regulations and the First Amendment right to free speech. Professional standards for medical advertising, such as guidelines published by the American Society for Reproductive Medicine (ASRM), the American College of Obstetricians and Gynecologists (ACOG), and the American Medical Association (AMA), are also summarized. A number of claims, many of which relate to the targeting of younger women for eOC, are found to breach legal and ethical standards for truth in advertising. The ethical implications of misleading advertising claims are also discussed, and the central narrative woven by OC ads - that egg freezing is empowering to women - is examined. The paper concludes that a more balanced approach to the risks and benefits of OC is necessary to truly respect women's autonomy. Moreover, justice requires us to look beyond a medical procedure accessible only to a minority of women in order to address inequities in the workplace.

Abstract
BACKGROUND AND OBJECTIVES Necrotizing enterocolitis is a common gastrointestinal disease in newborns, especially in preterm infants. Our study analyzed the value of fecal calprotectin as a biomarker in the diagnosis of NEC based on previous studies that have confirmed elevated calprotectin levels in NEC patients. METHOD We searched several databases including PubMed, Medline, Web of Science and Cochrane Library to identify studies of humans investigating the performance characteristics of fecal calprotectin for the diagnosis of NEC. The quality of included studies was assessed by RevMan5 software (QUADAS-2). The sensitivity, specificity and other measurements of accuracy of fecal calprotectin were pooled using Meta-DiSc software. RESULT A total 10 studies with 568 patients included in our meta-analysis. The pooled sensitivity, specificity, diagnostic odds ratio (DOR) and AUC were: 0.86 (95%CI: 0.80-0.91), 0.79 (95%CI: 0.75-0.83), 34.78 (95% CI: 15.30 to 79.07) and 0.92. The pooled sensitivity, specificity, DOR and AUC of subgroup analysis were: 0.85 (95%CI: 0.79-0.90), 0.89 (95%CI: 0.85-0.92), 41.03 (95% CI: 16.87 to 99.78) and 0.92 for nine studies using ELISA; 0.85 (95%CI: 0.79-0.90), 0.89 (95%CI: 0.85-0.92), 42.08 (95% CI: 18.44 to 96.04) and 0.93 for six prospective studies; 0.91 (95%CI: 0.82-0.97), 0.93 (95%CI: 0.88-0.96), 69.51 (95% CI: 17.67 to 273.40) and 0.95 for four studies of preterm infants. 0.86 (95%CI: 0.77-0.92), 0.94 (95%CI: 0.90-0.97), 53.23 (95% CI: 15.68 to 180.73) and 0.94 five studies that defined NEC as stage II or above. CONCLUSION Fecal calprotectin is a promising biomarker with high diagnostic value in neonatal, especially in premature infants.

Abstract
BACKGROUND Neonates with abdominal wall defects are at an increased infection risk because of the defect itself and prolonged neonatal intensive care unit (NICU) stays. Antibiotic prophylaxis until closure of the defect is common. However, infection risk and antibiotic use have not been well quantified in these infants. METHODS A retrospective cohort study of infants with abdominal wall defects (gastroschisis and omphalocele) admitted to a single-center NICU from 2007 to 2018. Demographic and clinical information, including microbiologic studies, antibiotic dosing and surgical care, were collected. Antibiotic use was quantified using days of therapy (DOT) per 1000 patient-days. Sepsis was defined as culture of a pathogen from a normally sterile site. RESULTS Seventy-four infants were included; 64 (86%) with gastroschisis and 10 (14%) with omphalocele. Median day of closure was 8 days [interquartile range (IQR) 6-10, range 0-31]. All infants received ≥1 course of antibiotics; median antibiotic DOT/infant was 24.5 (IQR 18-36) for an average of 416.5 DOT per 1000 patient-days. Most antibiotic use was preclosure prophylaxis (44%) and treatment of small intestinal bowel overgrowth (24%). Suspected and proven infection accounted for 26% of all antibiotic use. Skin and soft tissue infection (13/74, 18%) and late-onset sepsis (11/74, 15%) were the most common infections; 2 infants had sepsis while on antibiotic prophylaxis. All infants survived to discharge. CONCLUSIONS Most antibiotic use among infants with abdominal wall defects was prophylactic. Infection on prophylaxis was rare, but 35% of infants had infection after prophylaxis. Improved stewardship strategies are needed for these high-risk infants.

Abstract
Contrast material-enhanced US is a technique that is approved by the U.S. Food and Drug Administration for the characterization of liver lesions and intravesicular applications in children; however, contrast-enhanced US has several other pediatric applications in clinical practice. The most common application is for patients with inflammatory bowel disease (IBD). Contrast-enhanced US can be used to diagnose IBD, distinguish regions of active or chronic inflammation of the bowel wall, and evaluate associated complications such as abscesses, fistulas, and strictures. Dynamic contrast material evaluation provides qualitative and quantitative information about mural and mesenteric blood flow, which is essential in the determination of disease activity in these patients. It also has the potential to provide a means of monitoring the response to therapy beyond endoscopy or MR enterography. In addition to its use for IBD, contrast-enhanced US can be used to assess for bowel perfusion when problem solving in patients with necrotizing enterocolitis, neonatal bowel infarction, or intussusception. It is a useful imaging technique to fortify diagnoses that may otherwise be indeterminate, such as appendicitis, epiploic appendagitis, intraluminal bowel masses, and complex cysts. Finally, innovative applications such as shear-wave elastography have the potential to provide information about the stiffness of the bowel wall. Online supplemental material is available for this article. ©RSNA, 2020 See discussion on this article by Watson and Humphries.

Abstract
BACKGROUND Recently a new continuous non-invasive cardiac output measurement, bioreactance, has become available. Bioreactance measurement of cardiac output has been shown to correlate with left ventricular output detected by echocardiography in healthy term and preterm neonates. AIMS Our aim was to correlate cardiac output measurements by bioreactance in the first 48 h of life with adverse outcomes attributable to hypoperfusion (peri/intraventricular haemorrhage (PIVH) and/or necrotising enterocolitis (NEC)) in the cohort of extremely preterm infants. STUDY DESIGN A prospective observational cohort study. SUBJECTS Preterm infants with birth weight less than 1250 g. OUTCOME MEASURES Cardiac output was measured between six and 48 h of age by bioreactance. Our primary outcome was a difference in cardiac output between infants with an adverse outcome attributable to hypoperfusion (Group 1), and infants without the predefined adverse outcome (Group 2). RESULTS There were 39 infants enrolled in the study. There were six infants in Group 1. These infants had a significantly lower minimal cardiac output measurement compared to Group 2 (mean 36.7 ml/kg/min vs 64.5 ml/kg/min, p = .0006). The mean cardiac output in Group 1 was significantly lower on day one of life, followed by a significant increase in cardiac output on day two of life compared to Group 2. CONCLUSIONS Infants with birth weight less than 1250 g and PIVH and/or NEC had significantly lower cardiac output compared to infants without these complications on day one of life. This low cardiac output was then followed by a significant increase on day two of life.

Abstract
BACKGROUND Preterm birth may result in short- and long-term health problems for the child. Accurate diagnoses of preterm births could prevent unnecessary (or ensure appropriate) admissions into hospitals or transfers to specialist units. OBJECTIVES The purpose of this report is to assess the test accuracy, clinical effectiveness and cost-effectiveness of the diagnostic tests PartoSure™ (Parsagen Diagnostics Inc., Boston, MA, USA), Actim® Partus (Medix Biochemica, Espoo, Finland) and the Rapid Fetal Fibronectin (fFN)® 10Q Cassette Kit (Hologic, Inc., Marlborough, MA, USA) at thresholds ≠50 ng/ml [quantitative fFN (qfFN)] for women presenting with signs and symptoms of preterm labour relative to fFN at 50 ng/ml. METHODS Systematic reviews of the published literature were conducted for diagnostic test accuracy (DTA) studies of PartoSure, Actim Partus and qfFN for predicting preterm birth, the clinical effectiveness following treatment decisions informed by test results and economic evaluations of the tests. A model-based economic evaluation was also conducted to extrapolate long-term outcomes from the results of the diagnostic tests. The model followed the structure of the model that informed the 2015 National Institute for Health and Care Excellence guidelines on preterm labour diagnosis and treatment, but with antenatal steroids use, as opposed to tocolysis, driving health outcomes. RESULTS Twenty studies were identified evaluating DTA against the reference standard of delivery within 7 days and seven studies were identified evaluating DTA against the reference standard of delivery within 48 hours. Two studies assessed two of the index tests within the same population. One study demonstrated that depending on the threshold used, qfFN was more or less accurate than Actim Partus, whereas the other indicated little difference between PartoSure and Actim Partus. No study assessing qfFN and PartoSure in the same population was identified. The test accuracy results from the other included studies revealed a high level of uncertainty, primarily attributable to substantial methodological, clinical and statistical heterogeneity between studies. No study compared all three tests simultaneously. No clinical effectiveness studies evaluating any of the three biomarker tests were identified. One partial economic evaluation was identified for predicting preterm birth. It assessed the number needed to treat to prevent a respiratory distress syndrome case with a 'treat-all' strategy, relative to testing with qualitative fFN. Because of the lack of data, our de novo model involved the assumption that management of pregnant women fully adhered to the results of the tests. In the base-case analysis for a woman at 30 weeks' gestation, Actim Partus had lower health-care costs and fewer quality-adjusted life-years (QALYs) than qfFN at 50 ng/ml, reducing costs at a rate of £56,030 per QALY lost compared with qfFN at 50 ng/ml. PartoSure is less costly than Actim Partus while being equally effective, but this is based on diagnostic accuracy data from a small study. Treatment with qfFN at 200 ng/ml and 500 ng/ml resulted in lower cost savings per QALY lost relative to fFN at 50 ng/ml than treatment with Actim Partus. In contrast, qfFN at 10 ng/ml increased QALYs, by 0.002, and had a cost per QALY gained of £140,267 relative to fFN at 50 ng/ml. Similar qualitative results were obtained for women presenting at different gestational ages. CONCLUSION There is a high degree of uncertainty surrounding the test accuracy and cost-effectiveness results. We are aware of four ongoing UK trials, two of which plan to enrol > 1000 participants. The results of these trials may significantly alter the findings presented here. STUDY REGISTRATION The study is registered as PROSPERO CRD42017072696.

Abstract
The 2019 Necrotizing Enterocolitis (NEC) Symposium expanded upon the NEC Society's goals of bringing stakeholders together to discuss cutting-edge science, potential therapeutics and preventative measures, as well as the patient-family perspectives of NEC. The Symposium facilitated discussions and shared knowledge with the overarching goal of creating "A World Without NEC." To accomplish this goal, new research to advance the state of the science is necessary. Over the last decade, several established investigators have significantly improved our understanding of the pathophysiology of NEC and they have paved the way for the next generation of clinician-scientists funded to perform NEC research. This article will serve to highlight the contributions of these young clinician-scientists that seek to elucidate how immune, microbial and nervous system dysregulation contributes to the pathophysiology of NEC.

Abstract
Objective To examine cerebral oxygenation and perfusion in small for gestational age (SGA) compared with appropriate for gestational age (AGA) neonates during the first postnatal week, and to investigate any association with neurodevelopmental outcomes at 24-36 months of age. Methods A prospective matched case-control study was conducted evaluating cerebral oxygenation and perfusion, using near-infrared spectroscopy (NIRS), between SGA and AGA neonates, during the first postnatal week. A neurodevelopmental assessment with Bayley-III was performed at 24-36 months of age. Results Forty-eight SGA and 48 AGA neonates of similar gestation (32.8 ± 2.1 vs. 32.5 ± 1.9) were enrolled. On the first postnatal day, the cerebral oxygenation was equal between SGA and AGA neonates (71 ± 7% vs. 72 ± 8%); however, in the subgroup analysis, males had higher oxygenation compared to female SGA neonates (73 ± 7% vs. 69 ± 7%, P = 0.04). Cerebral perfusion was significantly higher in SGA neonates on the first postnatal day (1.4 ± 0.6 vs. 1.1 ± 0.5, P = 0.04), but this difference was diminished on subsequent measurements. There were no significant differences between the SGA and AGA infants regarding the composite cognitive, communication and motor index scores. The length of mechanical ventilation and late-onset sepsis were significant risk factors affecting the cognitive and communication composite index scores, respectively. Conclusion Cerebral oxygenation was equal between SGA and AGA neonates, while cerebral perfusion was transiently increased in SGA neonates during the first postnatal day. There was no significant association of cerebral oxygenation and perfusion with neurodevelopmental outcomes.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is the most common life-threatening gastrointestinal emergency associated with prematurity. Timely diagnosis and adequate treatment are crucial to reduce the morbidity and mortality of the affected infants. The aim of this study was to evaluate the diagnostic yield of bowel dilatation on plane abdominal radiography (AR) in the early diagnosis and NEC severity in preterm infants. METHODS We retrospectively reviewed initial ARs of 50 preterm infants with NEC ≥ stage II admitted to the neonatal intensive care unit (NICU) in a tertiary-care hospital. The largest bowel loops diameters (AD), the latero-lateral diameters of the peduncle of the first lumbar vertebra (L1), and the distance of the upper edge of the first lumbar vertebra and the lower edge of the second one, including the disc space (L1-L2), were measured. All anteroposterior ARs were done in a supine projection on the day of onset of the initial symptoms of NEC. RESULTS Preterm infants with surgical NEC showed a statistically significant increase in the AD/L1 ratio (p < 0.001) and AD/L1-L2 ratio (p < 0.001) compared with preterm infants with medical NEC. We found no significant association between the site of the most distended bowel loop and the severity of NEC (p > 0.05). CONCLUSION Bowel loop distension on initial AR may serve as an additional diagnostic tool in the early diagnosis and severity of stages II/III NEC. Further prospective clinical studies should validate the results from this study.

Abstract
Introduction: Necrotizing enterocolitis (NEC) affects mainly preterm infants, has a multifactorial etiology and is associated with intestinal dysbiosis and disordered immunity. Use of probiotics for prophylaxis is beneficial with studies indicating reduction in NEC ≥ stage 2, late onset sepsis (LOS) and mortality. However, not all studies have shown a reduction, there are questions regarding which probiotic to use, whether infants <1,000 g benefit and the risk of probiotic sepsis. All neonatal intensive care units in New Zealand (NZ) use probiotics and contribute to an international database (Australian and New Zealand Neonatal Network or ANZNN). Objective: To use ANZNN data to investigate the experience of NZ neonatal units with probiotics for NEC prevention in a setting where the baseline incidence of severe NEC was low, to compare results of 2 commonly used probiotic regimes and report on the extremely low birth weight subgroup. Method: Outcomes before (Pre group 2007-2010) and after (Probiotic group 2013-2015) starting routine probiotics for preterm infants <1,500 g or <32 weeks were compared. Clinicians reviewed cases to ensure they met database criteria. Five units used Infloran (Bifidobacterium bifidum and Lactobacillus acidophilus) and 1 unit used Lactobacillus GG (LGG) and bovine lactoferrin (bLF). Results: Four thousand five hundred and twenty nine infants were included and Pre and Probiotic groups were well-balanced with regard to gestation, birth weight and gender. The incidence of NEC in the Probiotic group was 1.6 and 2.7% in the pre group (corrected OR 0.62 CI 0.41-0.94). There was one case of probiotic sepsis. There was no significant difference between the Infloran and LGG/bLF combinations in regard to observed NEC rates. Late onset sepsis rates were significantly lower in the Probiotic group (p < 0.01). Conclusions: Introduction of probiotics for preterm infants in NZ has been associated with significant reductions in NEC and late onset sepsis.

Abstract
The goal of the NEC-Zero project is to reduce the burden of necrotizing enterocolitis (NEC) by increasing access to evidence-based tools to help clinicians and parents integrate evidence into daily care. It involves (a) human milk feeding with prioritized mother's own milk; (b) use of a unit-adopted standardized feeding protocol; (c) a unit-adopted strategy for timely recognition that integrates risk awareness and a structured communication tool when symptoms develop; and (d) stewardship of empiric antibiotics and avoidance of antacids. A toolkit for caregivers and parents was developed to make implementation consistent. For clinicians the toolkit includes: the GutCheckNEC risk score, a structured communication tool, the "Avoiding NEC" checklist, and the NEC-Zero website. For parents, NEC-Zero tools include the website, three educational brochures in English and Spanish, and a collaborative care video produced with the NEC Society. This article describes the toolkit and how it has been accessed and used.

Abstract
BACKGROUND AND OBJECTIVES Necrotizing enterocolitis (NEC) is a common and often severe gastrointestinal emergency in newborn infants. While usually affecting (very) premature infants, an association between NEC and haemolytic disease of the foetus and newborn (HDFN) has been suggested. HDFN may be an additional risk factor to develop NEC. The objective of this study was to evaluate the occurrence of NEC in infants affected with moderate to severe HDFN in a large single centre cohort as compared to a broad population of infants without HDFN. MATERIALS AND METHODS Retrospective cohort study of medical records of neonates with and without HDFN, with a gestational age at birth ≥30 weeks and ≤38 weeks, and admitted to the Leiden University Medical Center between January 2000 and December 2016. RESULTS A total of 3284 patient records of infants born in the study period were reviewed and 317 cases of HDFN were identified. The incidence of NEC was significantly higher among infants with HDFN compared to infants without HDFN: 4/317 affected infants (1·3%) vs. 11/2967 affected infants (0·4%, relative risk 3·40, 95% confidence interval: 1·09-10·63). CONCLUSIONS We observed a higher incidence of NEC in an overall late preterm to near term population of infants with moderate to severe HDFN, compared to infants born without HDFN. The clinician taking care of an HDFN-affected infant should be cautious of this higher risk.

Abstract
In recent years, an aberrant gastrointestinal colonization has been found to be associated with an higher risk for postnatal sepsis, necrotizing enterocolitis (NEC) and growth impairment in preterm infants. As a consequence, the reasons of intestinal dysbiosis in this population of newborns have increasingly become an object of interest. The presence of a link between the gut and lung microbiome's development (gut-lung axis) is emerging, and more data show as a gut-brain cross talking mediated by an inflammatory milieu, may affect the immunity system and influence neonatal outcomes. A revision of the studies which examined gut and lung microbiota in preterm infants and a qualitative analysis of data about characteristic patterns and related outcomes in terms of risk of growing impairment, Necrotizing Enterocolitis (NEC), Bronchopulmonary Dysplasia (BPD), and sepsis have been performed. Microbiota take part in the establishment of the gut barrier and many data suggest its immune-modulator role. Furthermore, the development of the gut and lung microbiome (gut-lung axis) appear to be connected and able to lead to abnormal inflammatory responses which have a key role in the pathogenesis of BPD. Dysbiosis and the gut predominance of facultative anaerobes appear to be crucial to the pathogenesis and subsequently to the prevention of such diseases.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) is the need for oxygen therapy at 36 weeks postmenstrual age (PMA). Sildenafil has been shown to enhance the lung alveolarization and vascularization in newborn animal models after lung injury and has possible therapeutic potential for the prevention of BPD. OBJECTIVE To perform a proof-of-concept, Phase II, pilot randomized, double-blind, clinical trial to study the efficacy of sildenafil in preventing BPD, in postnatal (< 24 h), extremely and very preterm infants. METHODS This Phase II, pilot randomized, double-blind, clinical trial was conducted in the Neonatal Intensive Care Unit of Women's Wellness and Research Center, Doha, Qatar during 2012-2014. Infants of 240/7-296/7 weeks' gestation were eligible if they needed respiratory or oxygen support ≥ 25% at randomization, and if they were at a postnatal age of < 24 h at randomization. Forty preterm infants were randomly assigned to receive off-label oral sildenafil (0.5 mg/kg every 6 h) or a placebo solution, for one week. The primary endpoints were the incidence of BPD and death at 36 weeks PMA, and the side effects. Secondary outcomes included the incidence of BPD and the respiratory support at day 28 of life, duration of oxygen use, fraction of inspired oxygen use at 36 weeks and 28 days of life, duration of hospitalization, and the incidence of significant retinopathy of prematurity, severe intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, patent ductus arteriosus, and late sepsis. RESULTS No significant differences were observed between the sildenafil and placebo study groups in mortality at 36 weeks PMA (10% vs 20%, p = 1), respiratory support at 36 weeks (30% vs 25%, p = 0.57), and side effects (0% vs 0%). For all other secondary outcomes, no significant differences were detected. CONCLUSIONS While not associated with side effects, off-label oral sildenafil did not demonstrate benefits in the prevention of BPD or death in the extreme and very preterm infants. Future studies of dosing and efficacy that target different regimens of sildenafil are warranted before sildenafil is recommended for the prevention of BPD.

Abstract
OBJECTIVE To assess mortality and morbidities in very low birthweight (VLBW) infants before and after changing to a restrictive blood transfusion guideline (RTG). STUDY DESIGN This is a large retrospective study comparing outcomes of a liberal transfusion guideline (LTG) and RTG in VLBW infants admitted to a large single neonatal intensive care unit. Blood and platelet transfusion details, mortality, and diagnoses of frequently diagnosed morbidities were collected for each infant. RESULTS Mortality was similar between RTG and LTG groups (6.8% vs. 6.3%, p = 0.755). Rates of periventricular leukomalacia (PVL), retinopathy of prematurity (ROP), sepsis and the diagnosis of necrotizing enterocolitis (NEC) within 48 h of a PRBC transfusion were significantly lower with RTG (p < 0.05). Chronic lung disease was similar between groups. CONCLUSION RTG are safe compared to LTG, and are associated with lower rates of PVL, ROP, transfusion-associated cases of NEC and sepsis.

Abstract
Small intestinal Paneth cells, enteric glial cells (EGC), and goblet cells maintain gut mucosal integrity, homeostasis, and influence host physiology locally and through the gut-brain axis. Little is known about their roles during pregnancy, or how maternal malnutrition impacts these cells and their development. Pregnant mice were fed a control diet (CON), undernourished by 30% vs. control (UN), or fed a high fat diet (HF). At day 18.5 (term = 19), gut integrity and function were assessed by immunohistochemistry and qPCR. UN mothers displayed reduced mRNA expression of Paneth cell antimicrobial peptides (AMP; Lyz2, Reg3g) and an accumulation of villi goblet cells, while HF had reduced Reg3g and mucin (Muc2) mRNA and increased lysozyme protein. UN fetuses had increased mRNA expression of gut transcription factor Sox9, associated with reduced expression of maturation markers (Cdx2, Muc2), and increased expression of tight junctions (TJ; Cldn-7). HF fetuses had increased mRNA expression of EGC markers (S100b, Bfabp, Plp1), AMP (Lyz1, Defa1, Reg3g), and TJ (Cldn-3, Cldn-7), and reduced expression of an AMP-activator (Tlr4). Maternal malnutrition altered expression of genes that maintain maternal gut homeostasis, and altered fetal gut permeability, function, and development. This may have long-term implications for host-microbe interactions, immunity, and offspring gut-brain axis function.

Abstract
BACKGROUND Probiotic use in the neonatal intensive care unit (NICU) has been linked to reduced rates of necrotizing enterocolitis in preterm infants. Currently, in the United States, probiotic use within the NICU is limited despite being commonly used in other countries. PURPOSE To provide an overview of the current practices of using probiotics in preterm infants for the prevention of NEC in the NICU in preselected countries. METHODS A comprehensive literature search was conducted on PubMed and clinicaltrials.gov. Also, studies from 2 recent meta-analyses on the topic were reviewed for inclusion. Selection criteria were as follows: studies involving preterm infants using probiotics in the NICU, reporting on the impact of probiotic use on the incidence of necrotizing enterocolitis, published within the last 10 years and in the English language, and originating from the United States, Canada, or any European country. RESULTS Twenty-three studies were selected. The most common types of probiotics used were Bifidobacterium infantis and Lactobacillus rhamnosus. The most common frequency of administration was daily or twice day. Duration ranged from 10 days to the entire NICU stay. The dosage was commonly 1 billion colony-forming units daily but ranged from 12 million daily to 12 billion per kilogram daily. IMPLICATIONS FOR PRACTICE Examining the current practices of probiotic use in the NICU provides useful information as this adjunctive therapy rises in popularity. IMPLICATIONS FOR RESEARCH Refining methods of probiotic research for necrotizing enterocolitis prevention will improve safety and effectiveness and provide a framework for future clinical trials.

Abstract
PURPOSE Limited data exists for longitudinal growth outcomes in neonates with a history of necrotizing enterocolitis (NEC). We aimed to study 20-year growth outcomes in NEC survivors. METHODS A retrospective matched cohort study included neonates diagnosed with NEC and control subjects matched for birth year, birth weight, and gestational age who had at least one post-discharge follow-up. The primary outcome was growth, measured by length and weight until 20 years. Logistic regression was used to test the change in growth from birth until most recent encounter. RESULTS Five hundred twenty-seven neonates were included: 294 with NEC, and 233 controls. Sixty-eight percent of NEC cases were Bell's stage I, 25% were stage II, and 7% were stage III. Median gestational age was 29 weeks, and median birth weight was 1237 g. Infants with NEC had a longer NICU stay (p < 0.0001) and increased number of comorbidities (p < 0.0001). Compared to overall and sex-matched controls, infants with NEC had a significantly slower growth rate in terms of weight (p < 0.0068) but not length (p = 0.09). Neither group exhibited failure to thrive. CONCLUSIONS These results suggest that non-surgical NEC may have a more profound impact on long-term growth than previously considered. TYPE OF STUDY Retrospective Cohort-Matched Study. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE Feeding intolerance is one of the most frequent problems among preterm infants. These infants are fed with expressed breast milk or preterm formulas of which the temperature is not routinely measured. In this study, we aimed to examine the effects of feeds with warm milk versus room temperature milk in preterm infants. MATERIALS AND METHODS Infants with a birth weight ≤1,500 g or gestational age ≤34 weeks were included in the study and assigned to two different feeding temperature groups (22-24°C and 32-34°C). Some infants in both groups were exclusively breast milk-fed, and some received breast milk and artificial milk (mixed feeding). Feeding tolerance of infants in both groups and the consequences were evaluated. RESULTS In total, 80 preterm infants (group 1 fed with milk at 22-24°C, n = 40; group 2 fed with milk at 32-34°C, n = 40) were prospectively included in the study. There was a slight decrease in gastric residual frequency in infants fed with breast milk in group 2. Apnea was significantly more frequent in group 1 (p = 0.006), and these infants needed more anti-reflux treatment (p = 0.013). CONCLUSION According to our results, warming enteral feeds close to body temperature are encouraging especially due to the decrease in gastric residual frequency, apnea of prematurity, and need for anti-reflux treatment. More studies may confirm the positive effect of warm enteral feeds on feeding tolerance in preterm infants.

Abstract
BACKGROUND Premature neonates are often subjected to multiple transfusions with red blood cells during their hospitalization in the neonatal intensive care unit (NICU). The hemoglobin threshold for transfusion prior to discharge from the NICU varies significantly among different centers. The aim of the present study is to investigate the association between hemoglobin concentration at discharge with neurodevelopmental outcomes in premature neonates. METHODS Retrospective observation study with regression analysis was performed with follow up assessment in the neuro-developmental outpatient clinic at 30 months of adjusted age. RESULTS Data from 357 neonates born at less than 37 weeks' gestation were analyzed. Sensory and motor neurodevelopment at 30 months of adjusted age, were not associated with the hemoglobin concentration at discharge (p=0.5891 and p=0.4575, respectively). There was no association between the hemoglobin concentration at discharge with fine or gross motor development (p=0.1582 and p=0.3805, respectively). Hemoglobin concentration at discharge was not associated with poor neurodevelopmental outcomes up until 30 months of adjusted age. CONCLUSIONS The data of the present study indicate that the hemoglobin concentration of premature neonates at the time of discharge is not associated with poorer markers of neurodevelopmental outcomes at 30 months of adjusted age. Comorbidities such as BPD and IVH that are present to premature neonates were identified as potential risk factors for certain aspects of the neurodevelopment.

Abstract
BACKGROUND Surgery for necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) is often complicated by intestinal failure (IF) and intestinal failure associated cholestasis (IFAC). OBJECTIVE Assessment of incidence, predictors, and mortality associated with IFAC in surgically treated NEC and SIP. METHODS A retrospective observational study based on hospital records during 1986-2014 in the two largest Finnish neonatal intensive care units was performed. IFAC was defined as conjugated bilirubin >34 μmol/l (2.0 mg/dl) for ≥ two postoperative weeks while receiving parenteral nutrition (PN). RESULTS In total 225 patients underwent surgery for NEC (n = 142; 63%) or SIP (n = 83; 37%). Included were 57 survivors with ≥two weeks PN. Sixty-five (42%) patients developed IFAC. Two-year survival with IFAC was 80% and without IFAC 89% (p = 0.13). Of the 65 patients with IFAC, all eight with unresolved IFAC died in comparison to six of 57 (11%) whose IFAC resolved (p < 0.0001), while IFAC resolved in all survivors. Survival among patients with resolved IFAC was 89% and with unresolved IFAC (n = 8) 0%, (p < 0.0001). IFAC lasted for median 83 (IQR 45-120) days and correlated with the duration of PN (R2 = 0.16, p = 0.03), delay of starting enteral feeds (R2 = 0.12, p = 0.05) and PN lipid emulsion (RR = 1.0 (95% CI = 1.0-1.1) (p = 0.02). In multivariate logistic regression analysis, IFAC development associated with septicemias and reoperations. CONCLUSIONS 42% of prematures who underwent surgery for NEC or SIP developed IFAC. Reoperations and septicemias increased the risk of IFAC. None of the patients with unresolved IFAC survived, but IFAC did not increase overall mortality. TYPE OF STUDY Retrospective prognosis study.

Abstract
AIM We determined the influence of cumulative dosing of caffeine citrate on the neurodevelopmental outcomes of low birth weight (VLBW) infants at 18-22 months of postmenstrual age. METHODS This retrospective chart analysis was conducted at Detroit Medical Center, Michigan, USA. The 181 infants we included were born between January 2006 and December 2016, were less than 32 weeks of gestational age and weighed less than 1500 grams. Data on their perinatal and postnatal characteristics were retrieved from their medical records and they were assessed using the Bayley Scales of Infant Development - Third Edition. RESULTS The 64 infants with no neurodevelopmental disability or a mild disability received a significantly higher average daily dose (mg/kg/day) of caffeine citrate with a median of 7.58 (range 2.7-12.2) mg/kg/day, than the 79 infants with a moderate to severe disability, who received a median of 6.47 (range 3.1-12.5, p = 0.01). The total cumulative dose had no effect on bronchopulmonary dysplasia or neurodevelopmental outcomes. CONCLUSION A higher average daily dose of caffeine citrate was associated with better neurodevelopmental outcomes of VLBW infants. However, the cumulative dose did not have an impact on their short-term or long-term outcomes. Further research is needed to confirm our findings.

Abstract
Bacterial colonization patterns in preterm infants differ from those of their term counterparts due to maternal microbial diversity, delivery mode, feeding methods, antibiotic use, and exposure to commensal microbiota and pathogens in the neonatal intensive care unit (NICU). Early gut microbiome dysbiosis predisposes neonates to necrotizing enterocolitis (NEC), a devastating intestinal disease with high morbidity and mortality. Though mechanisms of NEC pathogenesis are not fully understood, the microbiome is a promising therapy target for prevention and treatment. Direct administration of probiotics to preterm infants has been shown to reduce the incidence of NEC, but is not without risk. The immature immune systems of preterm infants leave them vulnerable to even beneficial bacteria. Further research is required to investigate both short-term and long-term effects of probiotic administration to preterm infants. Other methods of altering the preterm infant microbiome must also be considered, including breastfeeding, prebiotics, and targeting the maternal microbiome.

Abstract
BACKGROUND As advances in neonatal intensive care increase the survival of extremely premature infants, the at-risk population for necrotizing enterocolitis (NEC) continues to rise. Although racial health disparities in preterm births have been well documented, large-scale studies exploring racial differences in NEC outcomes are lacking. Here, we conduct a study of racial health disparities in NEC using a nationally representative multicenter cohort. STUDY DESIGN Infants ≤1500 g birth weight and ≤30 weeks gestational age admitted in the first week after birth to neonatal intensive care units in the Pediatrix Medical group from 1997 to 2015 were included. Multivariable logistic regression was used to determine the adjusted odds ratio (AOR) of risk factors related to NEC and associated mortality. RESULTS Of the 126,089 (45% non-Hispanic White, 27% non-Hispanic Black, and 19% Hispanic) infants who met the inclusion criteria, 8796 (7%) developed NEC. On multivariable analysis, non-Hispanic Black and Hispanic infants had higher odds of developing NEC (AOR 1.31, 95% confidence interval (CI) [1.24-1.39], p < 0.001 and AOR 1.30 [1.21-1.39], p < 0.001, respectively). Among infants with NEC, mortality was higher in non-Hispanic Black and Hispanic infants compared to non-Hispanic White infants (AOR 1.35 [1.15-1.58], p < 0.001 and AOR 1.31 [1.09-1.56], p = 0.003, respectively). CONCLUSION Our study demonstrates that non-Hispanic Black and Hispanic infants are significantly more likely to be diagnosed with NEC. In addition, non-Hispanic Black and Hispanic infants have higher odds of death after NEC compared to non-Hispanic White infants. Further studies are necessary to investigate the etiology of these health disparities and to test interventions to improve these health outcomes.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) are the most common abdominal surgical conditions in preemies. Associated mortality remains high and long periods of parenteral nutrition (PN) may be required. We assessed the developments in the outcomes of surgically treated NEC and SIP in the two largest Finnish neonatal intensive care units (NICU). METHODS Retrospective observational study based on hospital records during 1986-2014. Main outcome measures were three-month survival during 1986-2000 compared with 2001-2014 and predictors of mortality. RESULTS Included were 225 patients (NICU A 131 and NICU B 94) with NEC in 142 (63%) and SIP 83 (37%). The median birth weight (BW) (870 vs 900 g) and gestation age (GA) (27 vs 27 weeks, p = 0.96) were similar in NEC and SIP. Small intestine was affected in 85% of NEC and 76% of SIP patients (p = 0.12). In 5% of patients NEC was panintestinal. Median small intestinal loss was 25% in NEC and 4.0% in SIP (p < 0.001). Ileocecal valve was resected in 29% of NEC and 14% of SIP patients (p = 0.01). Enterostomy was performed in 78% of patients and primary anastomosis in 18%; 4% died of extensive NEC without definitive surgery. Overall survival was 74% (NEC 73%, SIP 77%, p = 0.48; NICU A 82%, NICU B 65%, p = 0.003). From 1986-2000 to 2001-2014 overall survival increased from 69 to 81% (p = 0.04). Treating NICU was the strongest predictor of survival, RR = 2.8 (95% CI = 1.4-5.1), p = 0.003. CONCLUSIONS Overall survival improved significantly from the early (1986-2000) to the late (2001-2014) study period. Strongest predictor of mortality was the treating neonatal intensive care unit.

Abstract
OBJECTIVE To analyze the influence of dilution, time, and temperature after preparation on the osmolality of infant formulas given to newborns (NBs). METHODS Experimental and descriptive study with samples of different neonatal formulas to verify the osmolality of the milk according to dilution, time, and temperature after preparation. We analyzed seven neonatal formulas in the following times after preparation: immediately (up to 5 minutes); 20 and 40 minutes; every hour up to 8 hours; and 12 and 24 hours. The samples were evaluated at room temperature and after refrigeration. Osmolality curves were designed with the mean of triplicate samples of each milk sample. The digital Osmometer A+, model 3320, from Advanced Instruments measured the osmolality. RESULTS The time and temperature at which the milk was subjected after preparation did not cause the osmolality to exceed its safety cut-off point at a 1:30 dilution in any of the types of milk analyzed. At a 1:25 dilution, the formula with prebiotics in its composition went over the limit after 4 hours. CONCLUSIONS The milk tested did not exceed the cut-off point of 450 mOsm/kg (approximately 400 mOsm/L), indicated as safe by the American Academy of Pediatrics (AAP) at a dilution recommended by manufacturers. It is important to know the factors that may or may not contribute to the rise of osmolality, in order to establish safe and quality practices for NBs, following protocols based on scientific evidence.

Commencing Nutrient Supplements before Full Enteral Feed Volume Achievement Is Beneficial for Moderately Preterm to Late Preterm Low Birth Weight Babies: A Prospective, Observational Study. Nutrients 2018; 10:nu10101340. [PMID: 30241325 PMCID: PMC6213071 DOI: 10.3390/nu10101340] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 09/10/2018] [Accepted: 09/18/2018] [Indexed: 11/30/2022] Open
Abstract
The aim of this study was to observe after following a routine change in the feeding protocol whether the earlier introduction of nutrient supplements improved nutritional outcomes in moderately preterm to late preterm low birth weight (LBW) babies. In this prospective observational study, LBW babies between 31 and 39 weeks’ gestation admitted to a Special Care Nursery were assigned to two groups (F80, n = 45, F160, n = 42) upon commencing nutrient supplement at total fluid intake achievement of 80 or 160 mL/kg/day. Outcomes included weight, protein intake, biochemical markers, feeding intolerance, and length of stay (LOS). F80 nutrient supplements commenced before F160 (2.8 vs. 6.7 days, p < 0.0001) and lasted longer (15.2 vs. 12.2 days, p < 0.03). Weight gain velocity and LOS were similar. F80 mean protein intake during the first 10 days was higher (3.38 vs. 2.74 g/kg/day, p < 0.0001). There were fewer infants with protein intake <3 g/kg/day in the F80 group (8% vs. 65%, p < 0001). F80 babies regained birthweight almost two days earlier (7.5 vs. 9.4 days, p < 0.01). Weight gain Z-scores revealed an attenuation of the trend towards lower weight percentiles in the F80 group. Feeding intolerance was decreased for F80 (24.4% vs. 47.6%, p < 0.03). There were no adverse outcomes. Earlier nutrient supplementation for LBW babies lifts mean protein intake to above 3 g/kg/day and reduces both the duration of post-birth weight loss and incidence of feeding intolerance.

Abstract
BACKGROUND Intestinal disorders are common in very low-birthweight infants. The purpose of this study was to evaluate the impact of prophylactic oral Gastrografin® (diatrizoate acid) on meconium-related ileus (MRI) in extremely preterm infants. METHODS This was a retrospective case-control study of infants born extremely preterm at <28 weeks of gestation and treated with diatrizoate acid (prophylactic group) or not (control group) in the periods 2007-2014 and 2000-2009, respectively. In the 2007-2014 period, 120 infants received prophylactic diatrizoate acid solution. From the 165 infants in the control group, we selected 120 infants matched for gestational age. Cases of death before 72 h of life or congenital abnormalities were excluded. Intestinal disorders, time until full enteral feeding, duration of hospital stay, mortality rate, and neurodevelopmental outcome were compared. RESULTS MRI occurred in six infants in the control group and in none of the infants in the prophylactic group (P = 0.039). Median time until full enteral feeding was 25 versus 22 days (P < 0.01), hospital stay was 142 versus 126 days (P < 0.01), and mortality rate for infants aged 24-27 weeks was 8.2% versus 0% (P = 0.021), respectively. CONCLUSIONS Prophylactic oral diatrizoate acid reduced MRI in extremely preterm infants without side-effects and decreased the mortality rate of infants born at 24-27 weeks, and is thus beneficial in extremely preterm infants.

Abstract
BACKGROUND Morbidity and mortality with necrotizing enterocolitis (NEC) remains a significant challenge. Acute kidney injury (AKI) has been shown to worsen survival in critically ill neonates. To our knowledge, this study is the first to evaluate the prevalence of AKI and its impact on outcomes in neonatal NEC. METHODS We carried out a single-center retrospective chart review of all neonates treated for NEC between 2003 and 2015 (N = 181). AKI is defined as a rise in serum creatinine (SCr) from a previous trough according to neonatal modified KDIGO criteria (stage 1 = SCr rise 0.3 mg/dL or SCr 150 < 200%, stage 2 = SCr rise 200 < 300%, stage 3 = SCr rise ≥300%, SCr 2.5 mg/dL or dialysis). Primary outcome was in-hospital mortality and secondary outcomes were hospital length of stay (LOS) and need for and type of surgery. RESULTS Acute kidney injury occurred in 98 neonates (54%), with 39 stage 1 (22%), 31 stage 2 (18%), and 28 stage 3 (16%), including 5 requiring dialysis. Non-AKI and AKI groups were not statistically different in age, weight, Bell's NEC criteria, and medication exposure (vasopressors, vancomycin, gentamicin, or diuretic). Neonates with AKI had higher mortality (44% vs 25.6%, p = 0.008) and a higher chance of death (HR 2.4, CI 1.2-4.8, p = 0.009), but the effect on LOS on survivors did not reach statistical significance (79 days, interquartile range [IQR] 30-104 vs 54 days, IQR 30-92, p = 0.09). Overall, 48 (27.9%) patients required surgical intervention. CONCLUSIONS This study shows that AKI not only occurs in over half of patients with NEC, but that it is also associated with more than a two-fold higher mortality, highlighting the importance of early recognition and potentially early intervention for AKI.

Abstract
Better means to diagnose and define necrotizing enterocolitis are needed to guide clinical practice and research. Adequacy of Bell's staging system for clinical practice and clarity of cases used in NEC clinical datasets has been a topic of controversy for some time. This article provides reasons why a better global definition for NEC is needed and offers a simple alternative bedside definition for preterm NEC called the "Two out of Three" rule. Some argue that biomarkers may fill knowledge gaps and provide greater precision in defining relevant features of a clinical disease like NEC. NEC biomarkers include markers of inflammation, intestinal dysfunction, hematologic changes, and clinical features. Development and reporting of NEC biomarkers should be guided by the FDA's BEST Consensus resource, "Biomarkers, EndpointS, & other Tools" and consistently report metrics so that studies can be compared and results pooled. Current practice in the NICU would be enhanced by clinical tools that effectively inform the clinical team that a baby is at increasing risk of NEC. Ideally, these tools will incorporate both clinical information about the baby as well as molecular signals that are indicative of NEC. While meaningful biomarkers for NEC and clinical tools exist, translation into practice is mediocre.

Abstract
AIM This Lebanese study tested the hypothesis that differences would exist in the gut microbiota of preterm infants with and without necrotising enterocolitis (NEC), as reported in Western countries. METHODS This study compared 11 infants with NEC and 11 controls, all born at 27-35 weeks, in three neonatal intensive care units between January 2013 and March 2015. Faecal samples were collected at key time points, and microbiota was analysed by culture, quantitative PCR (qPCR) and temperature temporal gel electrophoresis (TTGE). RESULTS The cultures revealed that all preterm infants were poorly colonised and harboured no more than seven species. Prior to NEC diagnosis, significant differences were observed by qPCR with a higher colonisation by staphylococci (p = 0.034) and lower colonisations by enterococci (p = 0.039) and lactobacilli (p = 0.048) in the NEC group compared to the healthy controls. Throughout the study, virtually all of the infants were colonised by Enterobacteriaceae at high levels. TTGE analysis revealed no particular clusterisation, showing high interindividual variability. CONCLUSION The NEC infants were poorly colonised with no more than seven species, and the controls had a more diversified and balanced gut microbiota. Understanding NEC aetiology better could lead to more effective prophylactic interventions and a reduced incidence.

Abstract
Despite increased efforts, the diverse etiologies of Necrotizing Enterocolitis (NEC) have remained largely elusive. Clinical predictors of NEC remain ill-defined and currently lack sufficient specificity. The development of a thorough understanding of initial gut microbiota colonization pattern in preterm infants might help to improve early detection or prediction of NEC and its associated morbidities. Here we compared the fecal microbiota successions, microbial diversity, abundance and structure of newborns that developed NEC with preterm controls. A 16S rRNA based microbiota analysis was conducted in a total of 132 fecal samples that included the first stool (meconium) up until the 5th week of life or NEC diagnosis from 40 preterm babies (29 controls and 11 NEC cases). A single phylotype matching closest to the Enterobacteriaceae family correlated strongly with NEC. In DNA from the sample with the greatest abundance of this phylotype additional shotgun metagenomic sequencing revealed Citrobacter koseri and Klebsiella pneumoniae as the dominating taxa. These two taxa might represent suitable microbial biomarker targets for early diagnosis of NEC. In NEC cases, we further detected lower microbial diversity and an abnormal succession of the microbial community before NEC diagnosis. Finally, we also detected a disruption in anaerobic microorganisms in the co-occurrence network of meconium samples from NEC cases. Our data suggest that a strong dominance of Citrobacter koseri and/or Klebsiella pneumoniae, low diversity, low abundance of Lactobacillus, as well as an altered microbial-network structure during the first days of life, correlate with NEC risk in preterm infants. Confirmation of these findings in other hospitals might facilitate the development of a microbiota based screening approach for early detection of NEC.

Abstract
AIM To evaluate the prevalence, risk factors and outcome of acute kidney injury (AKI) in very low birth weight (VLBW) infants.
METHODS In this retrospective study of VLBW infants, we analyzed the prevalence of AKI, as defined by changes in serum creatinine and urine output, associated risk factors and outcomes.
RESULTS A total of 293 VLBW infants (mean gestational age 28.7 wk) were included, of whom 109 weighed less than 1000 g at birth. The overall prevalence of AKI was 11.6% (22% in infants with a birth weight under 1000 g and 5.4% those heavier). A total of 19 (55%) affected infants died, with a mortality rate of 58% in infant less than 1000 g and 50% in those heavier. After adjusting for confounding variables, only necrotizing enterocolitis (NEC) remained associated with AKI, with odds ratio of 4.9 (95%CI: 1.9-18.6). Blood pressure and glomerular filtration rate (GFR) were not different between affected infants and the others upon discharge from hospital. A normal GFR was documented in all affected infants at one year of age.
CONCLUSION Using Kidney Disease Improving Global Outcomes definition of AKI, it occurred in over 10% of VLBW infants, more commonly in infants with lower birth weight. NEC was an independent associated risk factor. Renal function, as defined by GFR, was normal in all surviving affected infants 10 to 12 mo later.

Abstract
Necrotizing enterocolitis (NEC) is the most common acquired disease of the gastrointestinal tract (GIT) in premature infants and newborns. It is defined as an ulcerative inflammation of the intestinal wall. The clinical signs of incipient NEC are often very discrete, and range from localized intestinal symptoms to generalized signs of sepsis. NEC is classified depending on its severity into disease states according to the modified Bell's Classification. Treatment of NEC ranges, depending on its severity, from a conservative therapeutic approach to surgery with resection of the affected parts of the intestine. Mortality is considerably high in extremely small preterm infants reaching up to 42% of the affected children. Measures such as breastfeeding or alternatively nutrition with pasteurized human donor milk from a milk bank, administration of probiotics, avoidance of histamine type II receptor antagonists, and restrictive antibiotic treatment should be considered early on for prevention of NEC.

Abstract
Necrotising enterocolitis (NEC) and sepsis are serious diseases of preterm infants that can result in feeding intolerance, the need for bowel resection, impaired physiological and neurological development, and high mortality rates. Neonatal healthcare improvements have allowed greater survival rates in preterm infants leading to increased numbers at risk of developing NEC and sepsis. Gut bacteria play a role in protection from or propensity to these conditions and have therefore, been studied extensively using targeted 16S rRNA gene sequencing methods. However, exact epidemiology of these conditions remain unknown and the role of the gut microbiota in NEC remains enigmatic. Many studies have confounding variables such as differing clinical intervention strategies or major methodological issues such as the inability of 16S rRNA gene sequencing methods to determine viable from non-viable taxa. Identification of viable community members is important to identify links between the microbiota and disease in the highly unstable preterm infant gut. This is especially important as remnant DNA is robust and persists in the sampling environment following cell death. Chelation of such DNA prevents downstream amplification and inclusion in microbiota characterisation. This study validates use of propidium monoazide (PMA), a DNA chelating agent that is excluded by an undamaged bacterial membrane, to reduce bias associated with 16S rRNA gene analysis of clinical stool samples. We aim to improve identification of the viable microbiota in order to increase the accuracy of clinical inferences made regarding the impact of the preterm gut microbiota on health and disease. Gut microbiota analysis was completed on stools from matched twins (n = 16) that received probiotics. Samples were treated with PMA, prior to bacterial DNA extraction. Meta-analysis highlighted a significant reduction in bacterial diversity in 68.8% of PMA treated samples as well as significantly reduced overall rare taxa abundance. Importantly, overall abundances of genera associated with protection from and propensity to NEC and sepsis such as: Bifidobacterium; Clostridium, and Staphylococcus sp. were significantly different following PMA-treatment. These results suggest non-viable cell exclusion by PMA-treatment reduces bias in gut microbiota analysis from which clinical inferences regarding patient susceptibility to NEC and sepsis are made.

[PMID: 28323086 DOI: 10.1016/j.resuscitation.2017.03.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Revised: 03/02/2017] [Accepted: 03/07/2017] [Indexed: 11/30/2022]
Abstract
BACKGROUND Delivery room resuscitation of very low birth weight infants can involve use of endotracheal or intravenous epinephrine. Data of the past 19 years were reviewed to identify the usage of epinephrine in delivery room and identify characteristics of these babies. METHODS Neonates with ≤1500g birthweight from January 1996 to August 2014 were reviewed. Infants born alive and admitted to NICU were eligible. Characteristics such as demographics, survival and outcomes were recorded. Variables significant at p≤0.1 among neonates receiving epinephrine were further analyzed via multiple logistic regressions. RESULTS Out of 5868 eligible neonates, 416 (7%) received epinephrine in the delivery room. The infants who received epinephrine were of lower estimated gestational age (25 vs. 28wk) and lower birth weight (746 vs. 980g). Gender, race and mode of delivery were comparable between the two cohorts. Survival was higher in non-epinephrine group (89.4 vs. 61.1%). Bacterial infection (24.3 vs. 18.4%) and combined grade 3 and 4 intraventricular hemorrhage (18.4 vs. 8.4%) were higher in epinephrine group. Use of epinephrine in the delivery room was associated with decreased survival even after controlling for birth weight, gestational age and low Apgar scores [Odd ratio - 0.48 with 95% CI (0.37-0.62), p<0.001]. CONCLUSION Neonates with lower birth weight and younger gestational age were more likely to receive epinephrine during resuscitation at birth. Use of epinephrine in delivery room was associated with lower survival and severe intraventricular hemorrhage among very low birth weight infants.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) can become severe quickly, making early recognition a priority and understanding the occurrence of abdominal and clinical signs of impending NEC important. PURPOSE The purpose of this study was to examine relationships of abdominal signs up to 36 hours before diagnosis of NEC within subgroups treated medically, surgically, or those who died. METHODS A 3-site, descriptive correlational case-control design with retrospective data collection was used matching each NEC case to 2 controls (N = 132). RESULTS NEC cases were exposed to less human milk and fed later. Among them, 61% (n = 27) had at least 1 abdominal sign 36 hours before diagnosis, with fewer numbers having 2 (18%; n = 8) or 3 (5%; n = 2). At 36 hours before NEC, abdominal distension, duskiness, higher gastric residual, and greater count of abdominal signs were associated with severe NEC. No medical NEC cases had abdominal signs 36 or 24 hours before diagnosis. Highest severity of NEC was related to more abdominal signs at the times leading up to and at diagnosis of NEC. Gastric residuals were largely unrelated to NEC except for the most severe NEC at 36 hours before diagnosis. IMPLICATIONS FOR PRACTICE Communicating a count of abdominal signs may support earlier recognition and treatment of NEC. IMPLICATIONS FOR RESEARCH More research is needed to explore timing for clinical worsening of status (eg, surgical and NEC leading to death) and to study effective clinical approaches targeting early recognition to support timely action.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is the leading cause of neonatal gastrointestinal mortality; effective interventions are lacking with limited understanding of the pathogenesis of NEC. The importance of Toll-like receptor 4 (TLR4) signaling in NEC is well documented; however, the potential mechanisms that regulate enterocyte inflammation and apoptosis remain unclear. The aim of this study was to characterize the role of TLR4-mediated inflammation and apoptosis in the development of NEC and to determine the major apoptotic pathways and regulators in the process. METHODS TLR4-deficient C57BL/10ScNJ mice and lentivirus-mediated stable TLR4-silent cell line (IEC-6) were used. NEC was induced by formula gavage, cold, hypoxia, combined with lipopolysaccharide in vivo or lipopolysaccharide stimulation in vitro. Enterocyte apoptosis was evaluated by TUNEL or Annexin analysis. The expression of TLR4, caspase3, caspase8, caspase9, Bip, Bax, Bcl-2, and RIP was detected by Western blot and immunofluorescence. Inflammatory factors such as tumor necrosis factor-α and interleukin-2 were examined by Luminex. RESULTS Defect of TLR4 led to suppressed enterocytes apoptosis both in vitro and in vivo; the expression of caspase3, caspase8, Bip, and Bax was decreased; and caspase9 and Bcl-2 were increased. NEC severity was attenuated in TLR4-deficient mice compared with wild-type counterparts, and enterocytes apoptosis was correlated with NEC severity. RIP and cytokine level of tumor necrosis factor-α and interleukin-2 were also decreased. CONCLUSIONS TLR4-induced inflammation and apoptosis play a critical role in the pathogenesis of NEC. TLR4 inhibition, combined with extrinsic (caspase8) and/or endoplasmic reticulum stress (Bip) apoptosis signaling blockade could serve as a potential effective treating strategy for NEC.

Abstract
Preterm infants are extremely vulnerable to a range of morbidities and mortality. Underdeveloped cardiac, respiratory, gastrointestinal, and immune systems in the preterm period increase the risk of necrotizing enterocolitis (NEC), a serious disease of the gut. NEC affects 5-12% of very-low birth-weight infants, leads to surgery in 20-40% of cases, and is fatal in 25-50% of cases. There are multiple factors that may contribute to NEC, but the exact cause is not yet fully understood. Severe cases can result in intestinal resection or death, and the health care costs average >$300,000/infant when surgical management is required. Different types of nutrition may affect the onset or progression of NEC. Several studies have indicated that bovine milk-based infant formulas lead to a higher incidence of NEC in preterm infants than does human milk (HM). However, it is not clear why HM is linked to a lower incidence of NEC or why some infants fed an exclusively HM diet still develop NEC. An area that has not been thoroughly explored is the use of semielemental or elemental formulas. These specialty formulas are easy to digest and absorb in the gut and may be an effective nutritional intervention for reducing the risk of NEC. This review summarizes what is known about the factors that contribute to the onset and progression of NEC, discusses its health care cost implications, and explores the impact that different formulas and HM have on this disease.

Abstract
OBJECTIVES To assess whether TSH and fT4 have a role in the angiogenesis of vaso-obliteration and neovascularization which are the basic pathophysiology of ROP. METHODS In this retrospective case-control study, the control group (n = 56) included preterm newborns with risk for ROP while the laser group (n = 63) was recruited from cases who developed severe neovascularization and needed laser photocoagulation therapy. Considering the first (vaso-obliteration) and second (neovascularization) phases of the disease, in this study we researched the distribution of thyroid function tests between groups. RESULTS With regard to the first phase of the disease, TSH and fT4 showed no significant differences between the control and laser groups accordingly (P > 0.05). Likewise, in the second phase of ROP, there was no significant difference between the control and laser groups with respect to TSH and fT4 levels (P > 0.05). CONCLUSION We found that between the study groups, the levels of thyroid function tests did not have any significant differences, either in the first or the second phases of ROP which are the principal pathophysiology of the disease. Therefore, it was concluded that thyroid hormone values were not informative markers in the course of the disease in preterm babies at risk of developing ROP.

Paneth cells in the developing gut: when do they arise and when are they immune competent? Pediatr Res 2016; 80:306-10. [PMID: 27049291 DOI: 10.1038/pr.2016.67] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Accepted: 01/13/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND Little is known about the perinatal development of Paneth cells (PCs) during gestation and the relation with necrotizing enterocolitis (NEC). We aimed to investigate when PCs arise and when they become immune competent during gestation. METHODS We included 57 samples of ileum tissue of fetuses/infants with a gestional age (GA) between 9 and 40 wk taken as part of a standard autopsy procedure. Hematoxylin-eosin staining and anti-human defensin 5 immunohistochemistry were performed. We performed a semi-quantitative assessment of (immune-competent) PC numbers per 10 crypts per tissue section per GA. RESULTS The number of PCs and the number of immune-competent PCs increased with increasing GA (Spearman's ρ = 0.41, P = 0.002 and ρ = 0.61, P < 0.001, respectively). Whereas significantly higher PC numbers were observed after 37 wk gestation (median 7, range 0-12) compared to preterm infants (median 0, range 0-15; P = 0.002), we counted higher numbers of immune-competent PCs already in infants with GA above 29 wk (median 6, range 0-18) compared to infants with GA under 29 wk (median 2, range 0-9; P < 0.001). CONCLUSION The significant increase of immune-competent PCs starting from a GA of 29 wk mimics the rise in incidence of NEC during a similar postmenstrual age in preterm infants.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is known as an extremely painful childhood condition. OBJECTIVES The objective of this study was to explore pain management around NEC-related surgery in our neonatal intensive care unit (NICU) from a chart review of prospectively collected data on 60 operated NEC patients admitted between 2008 and 2013 with a median (IQR) gestational age of 28.3 (25.5-31.6) weeks. METHODS Pain medication data and pain scores (i.e. COMFORTneo and Numerical Rating Scale pain and distress scores) from 72 h before until 72 h after surgery were collected. RESULTS Preoperatively, 95% of the patients received morphine versus 100% postoperatively, with a median dosage of 10.0 (IQR 9.7-14.5) and 16.9 (IQR 10.1-20.0) μg/kg/h, respectively. Postoperatively, 28 patients (46.7%) received additional fentanyl intermittently and 14 (23.3%) received midazolam, which was part of palliative treatment for 6 patients (42.9%). In patients receiving pain medication, median COMFORTneo scores were 10 (IQR 10-11) preoperatively and 11 (10-12) postoperatively. The pain scores were comparable with those of other patients admitted to the NICU in the same time period. CONCLUSIONS Continuous morphine of 10 μg/kg/h preoperatively, with an increase to 15 μg/kg/h postoperatively, seems to constitute a good starting dose for further individualized pain management guided by pain scores.
