Zhou M, Duan PC, Li DL, Liang JH, Liang G, Xu H, Pan CW. Efficacy comparison of 21 interventions to prevent retinopathy of prematurity: a Bayesian network meta-analysis of randomized controlled trials. Eye (Lond) 2024; 38:877-884. [PMID: 37853107 DOI: 10.1038/s41433-023-02796-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 10/02/2023] [Accepted: 10/11/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND The objective of this study was to evaluate the comparative efficacy of current interventions for the prevention of retinopathy of prematurity (ROP) in premature infants. METHODS A network meta-analysis (NMA) was performed. We searched PubMed, Web of Science, Scopus, Embase, and the Cochrane Library for relevant studies from their inception to May 5, 2022. Publications were eligible for our study if they were randomized controlled trials (RCTs) involving preterm infants at <37 weeks of gestational age and reported the incidence of any-stage ROP treated with the interventions of interest. The overall effect was pooled using the random effects model. RESULTS We identified 106 RCTs (involving 23894 participants). This NMA showed that vitamin A supplementation markedly reduced the incidence of ROP, in comparison with placebo (odds ratio [OR] = 0.59, 95% credible interval [95% CrI] 0.33, 0.85), fish oil-based lipid emulsion (OR = 0.57, 95% CrI 0.24, 0.90), early erythropoietin (OR = 0.51, 95% CrI 0.34, 0.98), probiotics (OR = 0.48, 95% CrI 0.32, 0.97), and human milk (OR = 0.50, 95% CrI 0.21, 0.78). Vitamin A supplementation has the highest probability of being the best option for reducing the ROP risk compared with the other 20 interventions based on its surface under the cumulative ranking curve (SUCRA) value (SUCRA = 92.50%, 95% CrI 0.71, 1.00). CONCLUSIONS Our findings suggest that among 21 interventions, vitamin A supplementation might be the best method of preventing ROP. This NMA offers an important resource for further efforts to develop preventive strategies for ROP.

A Multifunctional, Low Cost and Sustainable Neonatal Database System. CHILDREN (BASEL, SWITZERLAND) 2024; 11:217. [PMID: 38397329 PMCID: PMC10887617 DOI: 10.3390/children11020217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2023] [Revised: 01/19/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024]
Abstract
Continuous improvement in the clinical performance of neonatal intensive care units (NICU) depends on the use of locally relevant, reliable data. However, neonatal databases with these characteristics are typically unavailable in NICUs using paper-based records, while in those using electronic records, the inaccuracy of data and the inability to customize commercial data systems limit their usability for quality improvement or research purposes. We describe the characteristics and uses of a simple, neonatologist-centered data system that has been successfully maintained for 30 years, with minimal resources and serving multiple purposes, including quality improvement, administrative, research support and educational functions. Structurally, our system comprises customized paper and electronic components, while key functional aspects include the attending-based recording of diagnoses, integration into clinical workflows, multilevel data accuracy and validation checks, and periodic reporting on both data quality and NICU performance results. We provide examples of data validation methods and trends observed over three decades, and discuss essential elements for the successful implementation of this system. This database is reliable and easily maintained; it can be developed from simple paper-based forms or used to supplement the functionality and end-user customizability of existing electronic medical records. This system should be readily adaptable to NICUs in either high- or limited-resource environments.

Abstract
Background In recent years, the number of neonatal surgeries has been on the rise despite the decline in the number of births, and we examined the actual trends and problems at Tottori University Hospital located in the Sanin region. Methods Medical records were retrospectively searched for patients who underwent major surgery during the neonatal period (within 30 days of age) at the Tottori University Hospital over the past 10 years (Jan. 2011 to Dec. 2020). Results Sixty-five cases were included. Early birth infants (< 37 gestational weeks) comprised 15 cases (23%) and low birth weight (< 2500 g) infants involved 27 cases (42%). In the latter half (2016-2020), early birth and low birth weight infants were significantly less than in the first half (2011-2015). The common diseases were anorectal malformation (14 cases), esophageal atresia (10), duodenal atresia (10), and diaphragmatic hernia (9). Prenatal diagnosis was obtained in 26 cases (40%), with high diagnostic rate obtained in duodenal atresia (100%), abdominal wall defect (100%), ileal atresia (75%), meconium peritonitis (67%), and diaphragmatic hernia (67%). Fifty-five cases (85%) were operated on within 7 days of age. Other major malformations were associated in 23 cases (35%). There were 6 deaths (9%), of which 3 cases were low birth weight infants with gastrointestinal perforation, 2 cases with severe chromosomal abnormalities (esophageal atresia, omphalocele), and 1 case with diaphragmatic hernia with severe pulmonary hypertension. Home medical care has been required with gastrostomy tube in 2 cases. Conclusion Neonatal surgery at Tottori University has been well performed as required with acceptable results along with the progression of other perinatal care. However, further investigation for improvements in premature delivery or organ hypoplasia may be required.

Abstract
Introduction In utero exposure to HIV and/or triple antiretroviral therapy (ART) have been shown to be associated with preterm births and low birth weight (LBW), but data from low-resources settings with high burden of HIV remain limited. This study utilized retrospective data to describe pregnancy outcomes among Rwandan women living with HIV (WLHIV) and HIV-negative women and to assess the association of HIV and ART with LBW. Methods This study used data from a large cohort of WLHIV and HIV-negative women in Rwanda for a cross-sectional analysis. Retrospective data were collected from antenatal care (ANC), delivery, and Prevention of Mother to Child Transmission (PMTCT) registries within the Central Africa International Epidemiology Databases to Evaluate AIDS (CA-IeDEA) in Rwanda. Data from women with documented HIV test results and known pregnancy outcomes were included in the analysis. Analyses for predictors of LBW (< 2,500 g) were restricted to singleton live births. Logistic models were used to identify independent predictors and estimate the odd ratios (OR) and 95% confidence intervals (CI) measuring the strength of their association with LBW. Results and discussion Out of 10,608 women with known HIV status and with documented pregnancy outcomes, 9.7% (n = 1,024) were WLHIV. We restricted the sample to 10,483 women who had singleton live births for the analysis of the primary outcome, LBW. Compared with HIV-negative women, WLHIV had higher rates of stillbirth, preterm births, and LBW babies. Multivariable model showed that WLHIV and primigravidae had higher odds of LBW. Lower maternal weight and primigravidae status were associated with greater odds of LBW. Among WLHIV, the use of ART was associated with significantly lower odds of LBW in a bivariate analysis. Even in a sample of relatively healthier uncomplicated pregnancies and women who delivered in low-risk settings, WLHIV still had higher rates of poor pregnancy outcomes and to have LBW infants compared to women without HIV. Lower maternal weight and primigravidae status were independently associated with LBW. Given that supplementary nutrition to malnourished pregnant women is known to decrease the incidence of LBW, providing such supplements to lower-weight WLHIV, especially primigravidae women, might help reduce LBW.

Abstract
At the inception of the Eunice Kennedy Shriver National Institute of Child Health and Development Neonatal Research Network (NRN), provision of care for extremely preterm (EPT) infants was considered experimental. The NRN Follow-up Study Group, initiated in 1993, developed infrastructure with certification processes and standards, allowing the NRN to assess 2-year outcomes for EPT and to provide important metrics for randomized clinical trials. This chapter will review the NRN Follow-up Study Group's contributions to understanding factors related to improved neurodevelopmental, behavioral, and social-emotional outcomes of EPT infants. We will also discuss follow up challenges, including reassessing which outcomes are most meaningful for parents and investigators. Finally, we will explore how outcome studies have informed clinical decisions and ethical considerations, given limitations of prediction of complex later childhood outcomes from early neurodevelopmental findings.

Abstract
The Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network (NRN) maintains a database of extremely preterm infants known as the Generic Database (GDB). Begun in 1987, this database now includes more than 91,000 infants, most of whom are extremely preterm (<29 weeks gestation). The GDB has been the backbone of the NRN, providing high quality, prospectively collected data to study the changing epidemiology of extreme prematurity and its outcomes over time. In addition, GDB data have been used to generate hypotheses for prospective studies and to develop new clinical trials by providing information about the numbers and characteristics of available subjects and the expected event rates for conditions and complications to be studied. Since its inception, the GDB has been the basis of more than 200 publications in peer-reviewed journals, many of which have had a significant impact on the field of neonatology.

Abstract
OBJECTIVE To compare the survival and morbidities of infants born between 22 0/7-25 6/7 weeks of gestation. STUDY DESIGN This observational cohort study consisted of 187 eligible infants liveborn at a single, Level III Neonatal Intensive Care Unit (NICU) between June 1, 2009, and December 31, 2016, in Cleveland, Ohio. Infants with recognized syndromes or major congenital malformations were excluded from the review. RESULT The rate of survival to discharge for NICU-admitted infants born at 22- and 23- week was 56% and 54% respectively at our institution. There was no trend observed between gestational ages and incidence of necrotizing enterocolitis (NEC), patent ductus arteriousus (PDA), sepsis, or severe intraventricular hemorrhage (IVH- Grade 3 or 4). The infants born at 22 weeks had a higher incidence of retinopathy of prematurity (ROP) as compared to 25 weeks gestation (p < 0.001). The need for home oxygen was significantly higher in the smallest infants 70% at 22 weeks, 62% and 60% at 23 and 24 weeks versus 33% at 25 weeks gestation (p < 0.007). Those born at 22 weeks had the same rate of survival to discharge with severe IVH as those born at 23 weeks but required fewer VP shunts (p > 0.52). CONCLUSIONS The course of extremely preterm infants shows no difference between those born at 22 and 23 weeks of gestation in our NICU with regards to both mortality and short-term morbidities, although they differed marginally from 24 week gestation infants and significantly from those born at 25 weeks gestation.

Abstract
BACKGROUND Neonatal bacterial meningitis (BM) has an incidence of 0.2-0.4 per 1,000 births and a mortality rate of 20-25%. Data from the Korean Neonatal Network (KNN) were evaluated to study the incidence, mortality, and risk factors associated with BM in very-low-birthweight (VLBW; <1,500 g) infants. METHODS We analyzed KNN data from 2013-2016 collected from 70 neonatal units. RESULTS The incidence of BM in VLBW infants was 40 out of 8,263 (0.5%). The 40 infants with BM had a mean gestational age of 27.1 ± 2.0 weeks and a mean birthweight of 1,036.8 ± 220.0 g. Mean age at diagnosis was 51.5 ± 38.3 days (range, 1-171). Infants with BM were divided into two groups: Group 1 (onset age ≤ 28 days) and Group 2 (onset age > 28 days). Coagulase-negative Staphylococcus (CONS) was the most common pathogen underlying meningitis in 11 of 40 cases (28%). BM co-occurred with bacteremia in 14 of 40) of cases (35%); bacteremia was significantly more common in Group 1 than Group 2 (P < 0.05). Seizure and intraventricular hemorrhage (≥grade 3) were significantly more prevalent in Group 2 than Group 1 (P < 0.05). The mortality rate of infants with BM was 4 out of 40 (10%), which was significantly lower than that of VLBW infants without BM (1,152/8,223, [14%]; P < 0.05). CONCLUSIONS The incidence of BM in VLBW infants was high, but the mortality rate was low. CONS was the most common pathogen of BM in VLBW infants.

Abstract
Background and objectives: The aims of this study were to examine the relationship between neurological outcomes at 3- and 6-months corrected age with the neurodevelopmental outcome at 3 years of age; to identify the perinatal/neonatal risk factors for poor neurodevelopmental outcomes at 3 years of age. Materials and methods: In our single-centre longitudinal cohort study, of the 73 consecutive infants admitted to our Neonatal Intensive Care Unit (NICU), 49 infants (80%) received both Hammersmith Infant Neurological Examination (HINE) at 3- and 6-months corrected age and Bayley–III neurodevelopmental assessment at 2–3 years chronological age. At 3 months follow up, 8.2% had suboptimal scores (below 10th percentile) on the HINE. At 6 months follow up, 4.1% had suboptimal scores (below 10th percentile) on the HINE. The means(±SD) for Bayley-III cognitive, language, and motor subscales were (96.3 ± 9.8), (99.9 ± 11.9), (93.2 ± 9.9). Results: At 3 months corrected age, higher total HINE scores and subscores for function of cranial nerves, posture, tone, were associated with better cognitive scores while poorer scores for function of cranial nerves, posture, movements, tone, and total HINE score were associated with lower motor scores. Infants with a HINE subscore of function of cranial nerves in the suboptimal range have three times higher odds of having a motor delay. Infants with a HINE subscore of function of cranial nerves in the suboptimal range have more than two times higher odds of having a language delay. At 6 months corrected age, poorer scores for function of cranial nerves, movements, tone, reflexes, and total HINE score were associated with worse Bayley-III motor scores whilst infants who have a total HINE score and a subscore of reflexes in the suboptimal range have four and seven times, respectively, higher odds of having a motor delay. Conclusions: Early identification of infants at risk for adverse long-term outcomes is essential in introducing early intervention therapies for optimizing neurodevelopmental outcomes.

Abstract
PURPOSE Premature births have a great impact on the parents. The purpose of this study was to investigate the anxieties of parents of premature infants regarding infantile diseases and to help medical staff better communicate with parents of premature infants. DESIGN AND METHODS This study included premature infants <37 weeks of age who were admitted to the Neonatal Intensive Care Unit of Kosin University Gospel Hospital between August 1, 2017, and December 31, 2017. The eligible subjects included 51 premature infants with their 75 parents (45 mothers and 30 fathers) listed in the children's medical records. Parental anxieties regarding the infants were determined by retrospective interviews at various time points as follows: before and after the birth, on postnatal Days 3 and 7, before discharge, in the first week after discharge, and at "whenever" time point. RESULTS The highest parental anxiety during all time points was regarding the respiratory system of the premature infants. Parental concerns regarding the metabolic-endocrine system of their infants significantly correlated with the presence of maternal diabetes mellitus. Parental anxiety significantly differed depending on the use of resuscitation after birth. A statistically significant difference in parental anxiety was observed in relation to the birth weight before discharge. The premature infants with bronchopulmonary dysplasia showed a significant difference in the level of parental anxiety concerning the infant's illness in the first week after discharge. CONCLUSIONS The parents of the premature infants were greatly concerned about their infants' respiratory system. Careful prenatal counseling and support are needed for mothers with diabetes.

Abstract
Background Inositol supplementation has been linked to beneficial effects on reducing the incidence of retinopathy of prematurity (ROP); however, it’s controversial. The meta-analysis aimed to check out the efficacy and safety of inositol supplementation in preterm infants for preventing ROP. Methods We conducted searches through PubMed, EMBASE, Medline, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, ClinicalTrials.gov website and conference proceedings. Randomized controlled trials comparing inositol supplementation with placebo were included. Two independent reviewers performed screening, review, and extraction. Statistical analysis was performed using R Project. Results Six studies (1194 infants) were proved eligible. In comparison with placebo, inositol supplementation revealed no effect on the incidence of severe ROP (relative risk [RR] = 0.49, 95% confidence interval [CI], 0.18–1.32; heterogeneity, P = .02; I2 = 66%; low quality of evidence [QOE]), mortality (RR = 1.25, 95% CI, 0.82–1.90; heterogeneity, P = .07; I2 = 51%; low QOE), all stages of ROP (RR = 0.98, 95% CI, 0.87–1.11; heterogeneity, P = .41; I2 = 0%; moderate QOE) and other adverse events. Sensitivity analysis showed an increased mortality in the inositol group (RR = 1.55, 95% CI, 1.14–2.11; heterogeneity, P = .30; I2 = 18%) after removing the study Hallman 1986, and meta-regression showed a significant association between publication year and efficacy of inositol compared with placebo (β = 0.1241; 95% CI, 0.0417–0.0026; z = 2.9527; p = .0032). Conclusions Based on current evidence, inositol supplementation showed no significant effect on preventing severe ROP, and exploratory sensitivity analysis showed a trend toward an increase on mortality.

Abstract
BACKGROUND Studying centre-to-centre (CTC) variation in mortality rates is important because inferences about quality of care can be made permitting changes in practice to improve outcomes. However, comparisons between hospitals can be misleading unless there is adjustment for population characteristics and severity of illness. OBJECTIVE We sought to report the risk-adjusted CTC variation in mortality among preterm infants born <32 weeks and admitted to all eight tertiary neonatal intensive care units (NICUs) in the New South Wales and the Australian Capital Territory Neonatal Network (NICUS), Australia. METHODS We analysed routinely collected prospective data for births between 2007 and 2014. Adjusted mortality rates for each NICU were produced using a multiple logistic regression model. Output from this model was used to construct funnel plots. RESULTS A total of 7212 live born infants <32 weeks gestation were admitted consecutively to network NICUs during the study period. NICUs differed in their patient populations and severity of illness.The overall unadjusted hospital mortality rate for the network was 7.9% (n=572 deaths). This varied from 5.3% in hospital E to 10.4% in hospital C. Adjusted mortality rates showed little CTC variation. No hospital reached the +99.8% control limit level on adjusted funnel plots. CONCLUSION Characteristics of infants admitted to NICUs differ, and comparing unadjusted mortality rates should be avoided. Logistic regression-derived risk-adjusted mortality rates plotted on funnel plots provide a powerful visual graphical tool for presenting quality performance data. CTC variation is readily identified, permitting hospitals to appraise their practices and start timely intervention.

Abstract
PURPOSE The aim of the study was to determine whether hyperpolarized He diffusion-weighted magnetic resonance imaging detects abnormalities in the lungs in children with bronchopulmonary dysplasia (BPD) as compared with age-matched normal children. MATERIALS AND METHODS All experiments were compliant with Health Insurance Portability and Accountability Act (HIPAA) and performed with Food and Drug Administration approval under an IND application. The protocol was approved by our Institutional Review Board, and written informed consent was obtained. Hyperpolarized He diffusion-weighted magnetic resonance imaging was performed in 16 subjects with a history of preterm birth complicated by BPD (age range, 6.8 to 13.5 y; mean, 9.0 y) and in 29 healthy term-birth subjects (age range, 4.5-14.7 y; mean, 9.2 y) using a gradient-echo sequence with bipolar diffusion gradients and with measurements at 2 b values (0 and 1.6 s/cm). Age-related comparison of the whole-lung mean apparent diffusion coefficient (ADC), 90th percentile ADC, and percentage of whole-lung volume with ADC>0.2 cm/s between the 2 groups was examined using ordinary least-squares multiple regression. RESULTS The mean ADC was significantly greater in subjects with BPD (0.187 vs. 0.152 cm/s, P<0.001). The 90th percentile ADC and mean percentage lung volume with ADC>0.2 cm/s were also higher in the BPD group (0.258 vs. 0.215 cm/s, 30.3% vs. 11.9%, P<0.001 for both). The body surface area-adjusted ventilated lung volume was similar in the 2 groups (1.93 vs. 1.91 L, P=0.90). CONCLUSIONS Children with BPD had higher ADCs and the same lung volumes when compared with age-matched healthy subjects, suggesting that children with BPD have enlarged alveoli that are reduced in number.

Abstract
OBJECTIVE To conduct a systematic review of neonatal necrotising enterocolitis (NEC) rates in high-income countries published in peer-reviewed journals. METHODS We searched MEDLINE, Embase and PubMed databases for observational studies published in peer-reviewed journals. We selected studies reporting national, regional or multicentre rates of NEC in 34 Organisation for Economic Co-operation and Development countries. Two investigators independently screened studies against predetermined criteria. For included studies, we extracted country, year of publication in peer-reviewed journal, study time period, study population inclusion and exclusion criteria, case definition, gestation or birth weight-specific NEC and mortality rates. RESULTS Of the 1888 references identified, 120 full manuscripts were reviewed, 33 studies met inclusion criteria, 14 studies with the most recent data from 12 countries were included in the final analysis. We identified an almost fourfold difference, from 2% to 7%, in the rate of NEC among babies born <32 weeks' gestation and an almost fivefold difference, from 5% to 22%, among those with a birth weight <1000 g but few studies covered the entire at-risk population. The most commonly applied definition was Bell's stage ≥2, which was used in seven studies. Other definitions included Bell's stage 1-3, definitions from the Centers for Disease Control and Prevention, International Classification for Diseases and combinations of clinical and radiological signs as specified by study authors. CONCLUSION The reasons for international variation in NEC incidence are an important area for future research. Reliable inferences require clarity in defining population coverage and consistency in the case definition applied.

Abstract
Periviable births are those occurring from 20 0/7 through 25 6/7 weeks of gestation. Among and within developed nations, significant variation exists in the approach to obstetric and neonatal care for periviable birth. Understanding gestational age-specific survival, including factors that may influence survival estimates and how these estimates have changed over time, may guide approaches to the care of periviable births and inform conversations with families and caregivers. This review provides a historical perspective on survival following periviable birth, summarizes recent and new data on gestational age-specific survival rates, and addresses factors that have a significant impact on survival.

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

Abstract
OBJECTIVE To compare rates of a composite outcome of mortality or major morbidity in very-preterm/very low birth weight infants between 8 members of the International Network for Evaluating Outcomes. STUDY DESIGN We included 58 004 infants born weighing <1500 g at 24(0)-31(6) weeks' gestation from databases in Australia/New Zealand, Canada, Israel, Japan, Spain, Sweden, Switzerland, and the United Kingdom. We compared a composite outcome (mortality or any of grade ≥3 peri-intraventricular hemorrhage, periventricular echodensity/echolucency, bronchopulmonary dysplasia, or treated retinopathy of prematurity) between each country and all others by using standardized ratios and pairwise using logistic regression analyses. RESULTS Despite differences in population coverage, included neonates were similar at baseline. Composite outcome rates varied from 26% to 42%. The overall mortality rate before discharge was 10% (range: 5% [Japan]-17% [Spain]). The standardized ratio (99% CIs) estimates for the composite outcome were significantly greater for Spain 1.09 (1.04-1.14) and the United Kingdom 1.16 (1.11-1.21), lower for Australia/New Zealand 0.93 (0.89-0.97), Japan 0.89 (0.86-0.93), Sweden 0.81 (0.73-0.90), and Switzerland 0.77 (0.69-0.87), and nonsignificant for Canada 1.04 (0.99-1.09) and Israel 1.00 (0.93-1.07). The adjusted odds of the composite outcome varied significantly in pairwise comparisons. CONCLUSIONS We identified marked variations in neonatal outcomes between countries. Further collaboration and exploration is needed to reduce variations in population coverage, data collection, and case definitions. The goal would be to identify care practices and health care organizational factors, which has the potential to improve neonatal outcomes.

Abstract
Emerging data suggest intraventricular hemorrhage (IVH) of the preterm neonate is a complex disorder with contributions from both the environment and the genome. Environmental analyses suggest factors mediating both cerebral blood flow and angiogenesis contribute to IVH, while candidate gene studies report variants in angiogenesis, inflammation, and vascular pathways. Gene-by-environment interactions demonstrate the interaction between the environment and the genome, and a non-replicated genome-wide association study suggests that both environmental and genetic factors contribute to the risk for severe IVH in very low-birth weight preterm neonates.

Abstract
CONTEXT Studies have suggested that human milk feeding decreases the incidence of retinopathy of prematurity (ROP); however, conflicting results have been reported. OBJECTIVE The aim of this meta-analysis was to pool currently available data on incidence of ROP in infants fed human milk versus formula. DATA SOURCES Medline, PubMed, and EBSCO were searched for articles published through February 2015. STUDY SELECTION Longitudinal studies comparing the incidence of ROP in infants who were fed human milk and formula were selected. Studies involving donor milk were not included. DATA EXTRACTION Two independent reviewers conducted the searches and extracted data. Meta-analysis used odds ratios (ORs), and subgroup analyses were performed. RESULTS Five studies with 2208 preterm infants were included. Searches including various proportions of human milk versus formula, any-stage ROP, and severe ROP were defined to pool data for analyses. For any-stage ROP, the ORs (95% confidence intervals [CIs]) were as follows: exclusive human milk versus any formula, 0.29 (0.12 to 0.72); mainly human milk versus mainly formula, 0.51 (0.26 to 1.03); any human milk versus exclusive formula, 0.54 (0.15 to 1.96); and exclusive human milk versus exclusive formula, 0.25 (0.13 to 0.49). For severe ROP, they were 0.11 (0.04 to 0.30), 0.16 (0.06 to 0.43), 0.42 (0.08 to 2.18), and 0.10 (0.04 to 0.29), respectively. LIMITATIONS Prospective randomized studies being impossible because of ethical issues, we chose observational studies for analysis. A few studies involving subgroup analyses presented high heterogeneity. CONCLUSIONS Based on current limited evidence, in very preterm newborns, human milk feeding potentially plays a protective role in preventing any-stage ROP and severe ROP.

Abstract
INTRODUCTION Newborn babies in need of critical medical attention are normally admitted to the neonatal intensive care unit (NICU). These infants tend to be preterm, have low birth weight, and/or have serious medical conditions. Neonatal survival varies, but progress in perinatal and neonatal care has notably diminished mortality rates. In this selected review, we examine and compare the NICU mortality rates and etiologies of death in different countries. METHODS A literature search was conducted in Ovid MEDLINE, OLDMEDLINE, EMBASE Classic, and EMBASE. The primary endpoint was the mortality rates in NICUs. Secondary endpoints included the reasons for death and the correlation between infant age and mortality outcome. For the main analysis, we examined all infants admitted to NICUs. Subgroup analyses included extremely low birth weight infants (based on the authors' own definition), very low birth weight infants, very preterm infants, preterm infants, preterm infants with a birth weight of ≤1,500 g, and by developed and developing countries. RESULTS The literature search yielded 1,865 articles, of which 20 were included. The total mortality rates greatly varied among countries. Infants in developed and developing countries had similar ages at death, ranging from 4 to 20 days and 1 to 28.9 days, respectively. The mortality rates ranged from 4 to 46% in developed countries and 0.2 to 64.4% in developing countries. CONCLUSION The mortality rates of NICUs vary between nations but remain high in both developing and developed countries.

Abstract
Prematurity is a major global health issue leading to high mortality and morbidity among the survivors. Neurodevelopmental disability (NDD) and retinopathy of prematurity (ROP) are the most common complications of prematurity. In fact, ROP is the second leading cause of childhood blindness in the world. Although there is much information regarding the occurrence of ROP and of NDD in premature infants, there have been few studies on ROP and its association with NDD. The objectives of this article are to review the current literature on the subject and to publish our own findings concerning the association between ROP and NDD in premature infants. The review suggests that although NDDs are related to degree of prematurity, NDD could also be the result of visual impairments resulting from ROP. Our own study shows a close association between NDD and zonal involvement of ROP: higher NDD if zone 1 is involved and less if zone 3 is involved.

Abstract
IMPORTANCE Extremely preterm infants contribute disproportionately to neonatal morbidity and mortality. OBJECTIVE To review 20-year trends in maternal/neonatal care, complications, and mortality among extremely preterm infants born at Neonatal Research Network centers. DESIGN, SETTING, PARTICIPANTS Prospective registry of 34,636 infants, 22 to 28 weeks' gestation, birth weight of 401 to 1500 g, and born at 26 network centers between 1993 and 2012. EXPOSURES Extremely preterm birth. MAIN OUTCOMES AND MEASURES Maternal/neonatal care, morbidities, and survival. Major morbidities, reported for infants who survived more than 12 hours, were severe necrotizing enterocolitis, infection, bronchopulmonary dysplasia, severe intracranial hemorrhage, cystic periventricular leukomalacia, and/or severe retinopathy of prematurity. Regression models assessed yearly changes and were adjusted for study center, race/ethnicity, gestational age, birth weight for gestational age, and sex. RESULTS Use of antenatal corticosteroids increased from 1993 to 2012 (24% [348 of 1431 infants]) to 87% (1674 of 1919 infants]; P < .001), as did cesarean delivery (44% [625 of 1431 births] to 64% [1227 of 1921]; P < .001). Delivery room intubation decreased from 80% (1144 of 1433 infants) in 1993 to 65% (1253 of 1922) in 2012 (P < .001). After increasing in the 1990s, postnatal steroid use declined to 8% (141 of 1757 infants) in 2004 (P < .001), with no significant change thereafter. Although most infants were ventilated, continuous positive airway pressure without ventilation increased from 7% (120 of 1666 infants) in 2002 to 11% (190 of 1756 infants) in 2012 (P < .001). Despite no improvement from 1993 to 2004, rates of late-onset sepsis declined between 2005 and 2012 for infants of each gestational age (median, 26 weeks [37% {109 of 296} to 27% {85 of 320}]; adjusted relative risk [RR], 0.93 [95% CI, 0.92-0.94]). Rates of other morbidities declined, but bronchopulmonary dysplasia increased between 2009 and 2012 for infants at 26 to 27 weeks' gestation (26 weeks, 50% [130 of 258] to 55% [164 of 297]; P < .001). Survival increased between 2009 and 2012 for infants at 23 weeks' gestation (27% [41 of 152] to 33% [50 of 150]; adjusted RR, 1.09 [95% CI, 1.05-1.14]) and 24 weeks (63% [156 of 248] to 65% [174 of 269]; adjusted RR, 1.05 [95% CI, 1.03-1.07]), with smaller relative increases for infants at 25 and 27 weeks' gestation, and no change for infants at 22, 26, and 28 weeks' gestation. Survival without major morbidity increased approximately 2% per year for infants at 25 to 28 weeks' gestation, with no change for infants at 22 to 24 weeks' gestation. CONCLUSIONS AND RELEVANCE Among extremely preterm infants born at US academic centers over the last 20 years, changes in maternal and infant care practices and modest reductions in several morbidities were observed, although bronchopulmonary dysplasia increased. Survival increased most markedly for infants born at 23 and 24 weeks' gestation and survival without major morbidity increased for infants aged 25 to 28 weeks. These findings may be valuable in counseling families and developing novel interventions. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00063063.

Abstract
OBJECTIVE To evaluate the maternal and perinatal outcomes of pregnancies delivered at 23+0 to 23+6 weeks' gestation. METHODS This prospective cohort study included women in the Canadian Perinatal Network who were admitted to one of 16 Canadian tertiary perinatal units between August 1, 2005, and March 31, 2011, and who delivered at 23+0 to 23+6 weeks' gestation. Women were included in the network if they were admitted with spontaneous preterm labour with contractions, a short cervix without contractions, prolapsing membranes with membranes at or beyond the external os or a dilated cervix, preterm premature rupture of membranes, intrauterine growth restriction, gestational hypertension, or antepartum hemorrhage. Maternal outcomes included Caesarean section, placental abruption, and serious complication. Perinatal outcomes were mortality and serious morbidity. RESULTS A total of 248 women and 287 infants were included in the study. The rate of Caesarean section was 10.5% (26/248) and 40.3% of women (100/248) had a serious complication, the most common being chorioamnionitis (38.6%), followed by blood transfusion (4.5%). Of infants with known outcomes, perinatal mortality was 89.9% (223/248) (stillbirth 23.3% [67/287] and neonatal death 62.9% [156/248]). Of live born neonates with known outcomes (n = 181), 38.1% (69/181) were admitted to NICU. Of those admitted to NICU, neonatal death occurred in 63.8% (44/69). Among survivors at discharge, the rate of severe brain injury was 44.0% (11/25), of retinopathy of prematurity 58.3% (14/24), and of any serious neonatal morbidity 100% (25/25). Two subgroup analyses were performed: in one, antepartum stillbirths were excluded, and in the other only centres that indicated they offered fetal monitoring at 23 weeks' gestation were included and antepartum stillbirths were excluded. In each of these, perinatal outcomes similar to the overall group were found. CONCLUSION Pregnant women delivering at 23 weeks' gestation are at risk of morbidity. Their infants have high rates of serious morbidity and mortality. Further research is needed to identify strategies and forms of management that not only increase perinatal survival but also reduce morbidities in these extremely low gestational age infants and reduce maternal morbidity.

The International Network for Evaluating Outcomes of very low birth weight, very preterm neonates (iNeo): a protocol for collaborative comparisons of international health services for quality improvement in neonatal care. BMC Pediatr 2014; 14:110.

Abstract
BACKGROUND The International Network for Evaluating Outcomes in Neonates (iNeo) is a collaboration of population-based national neonatal networks including Australia and New Zealand, Canada, Israel, Japan, Spain, Sweden, Switzerland, and the UK. The aim of iNeo is to provide a platform for comparative evaluation of outcomes of very preterm and very low birth weight neonates at the national, site, and individual level to generate evidence for improvement of outcomes in these infants. METHODS/DESIGN Individual-level data from each iNeo network will be used for comparative analysis of neonatal outcomes between networks. Variations in outcomes will be identified and disseminated to generate hypotheses regarding factors impacting outcome variation. Detailed information on physical and environmental factors, human and resource factors, and processes of care will be collected from network sites, and tested for association with neonatal outcomes. Subsequently, changes in identified practices that may influence the variations in outcomes will be implemented and evaluated using quality improvement methods. DISCUSSION The evidence obtained using the iNeo platform will enable clinical teams from member networks to identify, implement, and evaluate practice and service provision changes aimed at improving the care and outcomes of very low birth weight and very preterm infants within their respective countries. The knowledge generated will be available worldwide with a likely global impact.

Abstract
BACKGROUND Nebulized surfactant therapy has been proposed as an alternative method of surfactant administration. The use of a perforated vibrating membrane nebulizer provides a variety of advantages over conventional nebulizers. We investigated the molecular structure and integrity of poractant alfa pre- and post-nebulization. METHOD Curosurf® was nebulized using an Investigational eFlow® Nebulizer System. Non-nebulized surfactant ("NN"), recollected surfactant droplets from nebulization through an endotracheal tube ("NT") and nebulization of surfactant directly onto a surface ("ND") were investigated by transmission electron microscopy. Biophysical characteristics were assessed by the Langmuir-Wilhelmy balance and the Captive Bubble Surfactometer. RESULTS Volume densities of lamellar body-like forms (LBL) and multi-lamellar forms (ML) were high for "NN" and "NT" samples (38.8% vs. 47.7% for LBL and 58.2% vs. 47.8% for ML). In the "ND" sample, we found virtually no LBL's, ML's (72.6%) as well as uni-lamellar forms (16.4%) and a new structure, the "garland-like" forms (9.4%). Surface tension for "NN" and "NT" was 23.33 ± 0.29 and 25.77 ± 1.12 mN/m, respectively. Dynamic compression-expansion cycling minimum surface tensions were between 0.91 and 1.77 mN/m. CONCLUSION The similarity of surfactant characteristics of nebulized surfactant via a tube and the non-nebulized surfactant suggests that vibrating membrane nebulizers are suitable for surfactant nebulization. Alterations in surfactant morphology and characteristics after nebulization were transient. A new structural subtype of surfactant was identified.

Gene-environment interactions in severe intraventricular hemorrhage of preterm neonates. Pediatr Res 2014; 75:241-50.

Abstract
Intraventricular hemorrhage (IVH) of the preterm neonate is a complex developmental disorder, with contributions from both the environment and the genome. IVH, or hemorrhage into the germinal matrix of the developing brain with secondary periventricular infarction, occurs in that critical period of time before the 32nd to 33rd wk postconception and has been attributed to changes in cerebral blood flow to the immature germinal matrix microvasculature. Emerging data suggest that genes subserving coagulation, inflammatory, and vascular pathways and their interactions with environmental triggers may influence both the incidence and severity of cerebral injury and are the subject of this review. Polymorphisms in the Factor V Leiden gene are associated with the atypical timing of IVH, suggesting an as yet unknown environmental trigger. The methylenetetrahydrofolate reductase (MTHFR) variants render neonates more vulnerable to cerebral injury in the presence of perinatal hypoxia. The present study demonstrates that the MTHFR 677C>T polymorphism and low 5-min Apgar score additively increase the risk of IVH. Finally, review of published preclinical data suggests the stressors of delivery result in hemorrhage in the presence of mutations in collagen 4A1, a major structural protein of the developing cerebral vasculature. Maternal genetics and fetal environment may also play a role.

Abstract
Neonatal intensive care unit networks that encompass regions, states, and even entire countries offer the perfect platform for implementing continuous quality improvement initiatives to advance the health care provided to vulnerable neonates. Through cycles of identification and implementation of best available evidence, benchmarking, and feedback of outcomes, combined with mutual collaborative learning through a network of providers, the performance of health care systems and neonatal outcomes can be improved. We use examples of successful neonatal networks from across North America to explore continuous quality improvement in the neonatal intensive care unit, including the rationale for the formation of neonatal networks, the role of networks in continuous quality improvement, quality improvement methods and outcomes, and barriers to and facilitators of quality improvement.

Abstract
INTRODUCTION Intensive resuscitation at birth has been linked to intraventricular haemorrhage (IVH) in the preterm neonate. However, the impact of less intensive resuscitation on more subtle alterations in brain metabolic development is largely unknown. Our objective was to determine the relationship between the intensity of neonatal resuscitation following preterm birth on brain metabolic development. METHODS One hundred thirty-three very preterm-born neonates (median gestational age [GA] 27 ± 2 weeks) underwent MR spectroscopic imaging early in life (median postmenstrual age 32 weeks) and again at term-equivalent age (median 40 weeks). Severity of white matter injury, IVH and cerebellar haemorrhage on magnetic resonance imaging were scored. Ratios of N-acetylaspartate (NAA) and lactate to choline (Cho) were calculated in eight regions of interest and were assessed in relation to intensiveness of resuscitation strategy (bag and mask, continuous positive airway pressure [CPAP], intubation, cardiopulmonary resuscitation [CPR]). RESULTS Within the first hour of life, 14 newborns had no intervention, 3 received bag and mask, 30 had CPAP, 79 were intubated and 7 had CPR. Resuscitated infants were more likely to have IVH (p = 0.02). More intensive resuscitation was associated with decreased NAA/Cho maturation (p < 0.001, adjusting for birth GA). Metabolic development was similar in neonates requiring CPAP in comparison to those receiving no intervention. The change in lactate/Cho did not differ across resuscitation categories (p = 0.8). CONCLUSIONS Intensity of resuscitation at birth is related to changes in metabolic brain development from early in life to term-equivalent age. Results suggest that preventing the need for intensive neonatal resuscitation may provide an opportunity to improve brain development in preterm neonates.

Abstract
INTRODUCTION Intervention studies of developmental care for preterm infants in Western societies have shown early but unsustainable effects on child outcomes, however only a limited of studies have examined if developmental care interventions produce similar effects in Eastern cultural contexts. AIMS To examine the effectiveness of in-hospital developmental care on neonatal morbidity, growth and development of preterm infants with very low birth weight (VLBW; birth weight<1500 g) in Taiwan. METHODS One hundred and seventy-eight VLBW preterm infants were randomly assigned to the clinical trial during hospitalization at three hospitals in Taiwan; the control group received five sessions of standard child-focused developmental care and the intervention group received five sessions of child- and parent-focused developmental care. Sixty-two normal term infants were also included as a comparison group. Infants were examined for morbidity, growth and developmental outcomes at term age. RESULTS At study entry, more infants in the intervention group were twins or multiples than those in the control group (29% vs. 16%, p=0.05). After adjusting for birth set, the intervention group had lower incidences of stage II-III retinopathy (odds ratio [OR]=0.34 [95% confidence interval (CI): 0.15-0.79]; p=0.01) and feeding desaturation (OR=0.32 [95% CI: 0.10-1.00]; p=0.05) and had greater daily weight gains (difference=2.0 g/day [95% CI: 0-4.0 g/day]; p=0.05) as compared with the control group. However, the intervention and control groups did not differ in any of the neurodevelopmental measures. CONCLUSIONS In-hospital developmental care has short-term benefits for Taiwanese VLBW preterm infants in reducing the risk of retinopathy and feeding desaturation as well as in enhancing weight gains at term age.

Abstract
BACKGROUND Recent clinical observations of increased necrotizing enterocolitis (NEC) incidence in some nasal continuous positive airway pressure (NCPAP) patients raise concerns about whether the related abdominal distension is benign or contributes to NEC. We tested the hypothesis that mechanical strain causes an exaggerated enterocyte inflammatory response and decreased enterocyte growth and proliferation in the absence and presence of lipopolysaccharide (LPS). METHODS First we used a confluent enterocyte (IEC-6) monolayer to investigate effects of strain on inflammatory cytokine production and Toll-like receptor 4 (TLR-4) gene expression. Then we used a low seeding density to measure cell growth and proliferation. Ten percent mechanical strain was applied. RESULTS Significant increases in interleukin (IL)-8 and in IL-6 were observed after 8 and 24 h of cellular strain, respectively, and maintained throughout the study. TLR-4 expression was increased at 48 h. Mechanical strain led to slower proliferation and division whereas LPS alone had minimal effects. The responses of LPS and strain were supra-additive, suggesting synergistic cellular effects. CONCLUSION We speculate intestinal distension associated with the use of NCPAP, especially in the presence of abnormal gut colonization, may result in increased inflammatory cytokine production and be a contributing factor to neonatal intestinal morbidities.

Abstract
OBJECTIVE To define reference ranges for oxygen saturation (SpO(2) ) values in healthy full-term infants in the first days of life and in preterm infants off supplemental oxygen as they approach neonatal intensive care unit (NICU) discharge. METHODS From April 2009 to March 2010, we enrolled convenience samples of full-term infants from the newborn nursery and former preterm infants who did not require supplemental oxygen at the time of discharge from the NICU. Overnight SpO(2) and signal quality recordings were obtained and analyzed for duration of artifact-free recording time (AFRT), time (s) with SpO(2) less than several different target saturations (90-95%), and number of falls in SpO(2) by ≥4% and ≥10%. RESULTS We studied 102 full-term infants and 52 preterm infants. Preterm and full-term infants spent similar amounts of time less than 90%, 91%, 92%, 93%, 94%, and 95% although preterm infants had more falls in SpO(2) by ≥4% per hour of AFRT. Over 67% of term and preterm infants spent less than 6% of their time below 93%. CONCLUSION These data represent reference SpO(2) ranges for both preterm infants not requiring supplemental oxygen at NICU discharge and full-term infants in the first days of life. As we currently lack guidelines dictating the optimal target oxygen saturations for infants and the acceptable maximal time that they can safely spend below set target saturations, our data may serve as a guide to interpreting SpO(2) recordings of premature outpatient infants who are weaning from supplemental oxygen.

Abstract
Purpose: This randomized control trial investigated the relationship between soothability, weight gain, and length of hospital stay in premature infants. Method: Forty-eight preterm infants were randomized into control group or flaxseed pillow treatment group. The pillow group received two 15-minute treatments per day. Treatment consisted of placing a flaxseed-filled pillow on the infants’ upper thorax, once in the morning and once in the afternoon, for the infant’s first 5 days of life. Physiologic measurements were obtained pre- and posttreatment, including temperature, heart rate, respiratory rate, and pain scores and measures of physical activity. Findings: Infants in the treatment group demonstrated significant decreases in heart rate, respiratory rate, and pain scores compared to infants in the control group. Infants in the treatment group also gained more weight in the first 3 weeks of life and spent more time awake. Discharge weights and length of stay at hospital did not vary between the two groups. Conclusions: The flaxseed pillow is a new method that may assist premature infants to become more soothable and gain weight more rapidly in the first weeks of life. The pillow is inexpensive, easy to use, and not associated with adverse events. Further research is recommended to explore the efficacy of this intervention in other populations.

Abstract
OBJECTIVE The goal of this study was to delineate the epidemiology of echocardiographically diagnosed pulmonary hypertension (PH) in extremely low birth weight (ELBW) infants with bronchopulmonary dysplasia (BPD) requiring prolonged positive pressure ventilation (PPV), and to determine the independent relationship between PH and mortality in these patients. STUDY DESIGN Our retrospective cohort included ELBW infants, with BPD requiring prolonged PPV, hospitalized in Cincinnati, Ohio during 2003-2009, as recorded in the National Institute of Child Health and Human Development Neonatal Research Network Database. Following chart review, a logistic regression model was constructed to understand the contribution of PH to mortality in infants with BPD requiring prolonged PPV. RESULT We identified 216 patients (19%) with BPD requiring prolonged PPV among 1156 ELBW infants. Of these patients, 41% received echocardiography after 4 weeks of life, with 37% showing evidence of PH. Logistic regression analysis demonstrated that infants with BPD requiring prolonged PPV, with PH detectable by echocardiogram, were four times more likely to die (adjusted odds ratio): 4.6, 95% confidence interval: 1.3-16.5) when compared with infants with BPD requiring prolonged PPV without echocardiographic evidence of PH. CONCLUSION Pulmonary hypertension appears to be an important, independent determinant of death in infants with BPD requiring prolonged PPV.

Abstract
PURPOSE : With improvements in neonatal intensive care, more premature infants are surviving. Many have significant pulmonary morbidities after discharge from the hospital. Bronchopulmonary dysplasia is the most common morbidity of prematurity and is a common indication for home oxygen therapy in children. Data are lacking on the appropriate methods for weaning supplemental oxygen. The objective of this study was to identify the methods used by pediatric pulmonologists to wean premature infants from supplemental oxygen. SUBJECTS : One hundred eighty-four questionnaires were sent to pediatric pulmonologists at 20 pediatric pulmonary programs. DESIGN AND METHODS : This cross-sectional, self-administered anonymous survey assessed strategies for oxygen weaning for premature infants. MAIN OUTCOME MEASURES AND PRINCIPLERESULTS:: We had a 70% (14/20) institutional response rate. Of the responding institutions, we had a 73% (99/136) response rate. The majority of pulmonologists surveyed (78%) reported using nocturnal oxygen saturations as the primary indication for weaning. Only 8% of pulmonologists reported using a standardized protocol. Half of the respondents reported weaning diuretics prior to oxygen. The factors considered prior to initiating oxygen weaning included growth (96%), vital signs (85%), hospitalizations (68%), and echocardiograms (59%). Fewer respondents (21%) reported using chest x-ray findings. The minimum oxygen saturation in room air required to take a patient off oxygen ranged from 90% to 95%, with a mean of 93% (SD = 1.74). CONCLUSION : Pediatric pulmonologists reported a wide range of practice patterns in weaning premature infants from supplemental home oxygen. Very few respondents reported using a standardized protocol. There is no consensus about whether to wean diuretics or oxygen first. The majority of providers use nocturnal oxygen saturations as an indication for readiness to wean. Growth is an important factor for oxygen weaning considered by most pulmonologists surveyed. Consensus guidelines and subsequent evaluation of such guidelines are needed to ensure the safety of this growing population of infants.

Abstract
PURPOSE The objectives of this study were to translate and modify the Assessment of Mother-Infant Sensitivity scale into a Chinese version (modified AMIS-C) and to examine its reliability with preterm and term Taiwanese mother-infant dyads. METHOD A total of 241 mother-infant pairs (179 preterm dyads and 62 term dyads) were prospectively recorded and their behaviour in feeding assessed using the modified AMIS-C when infants were at 4 and 6 months corrected age. A subset of the sample was used for interrater reliability testing, and the whole sample was used for assessment of internal consistency. RESULTS Interrater reliability was high for the modified AMIS-C section and total scores (intra-class correlation coefficients=0.91-0.99). Internal consistency was good to excellent for the maternal section and total score (α=0.71-0.86) and was fair to good for the infant and dyadic section score (α=0.44-0.75). CONCLUSIONS The modified AMIS-C scale is a clinically feasible and reliable instrument for assessing mother-infant interaction of preterm and term dyads during early infancy.

Abstract
Advances in neonatology have led to increased survival at younger gestational ages. These advances have included the ability to provide and titrate oxygen, improved modalities of assisted ventilation, improved nutritional and environmental support, and surfactant therapy. As a result of increasing survival of these immature infants, bronchopulmonary dysplasia (BPD) has become a consistent outcome despite improvements in technology. Varying definitions of BPD have emerged in an effort to best identify infants at risk for long-term adverse outcome and those who might benefit most from preventive therapies. Underlying abnormal pulmonary development of extremely preterm infants in the face of exposure to oxygen, assisted ventilation and inflammation make this a complex, multifactorial disease. Recent focus has been directed at preventing and treating inflammation. Efforts to minimize the inflammatory process include avoiding hyperoxia, minimizing injury from assisted ventilation, and preventing and treating postnatal infections. Additional therapies to modulate inflammation, such as steroid therapy or inhaled nitric oxide, need further investigation of both short- and long-term outcomes before routine use can be recommended.

Abstract
OBJECTIVE This report presents data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network on care of and morbidity and mortality rates for very low birth weight infants, according to gestational age (GA). METHODS Perinatal/neonatal data were collected for 9575 infants of extremely low GA (22-28 weeks) and very low birth weight (401-1500 g) who were born at network centers between January 1, 2003, and December 31, 2007. RESULTS Rates of survival to discharge increased with increasing GA (6% at 22 weeks and 92% at 28 weeks); 1060 infants died at <or=12 hours, with most early deaths occurring at 22 and 23 weeks (85% and 43%, respectively). Rates of prenatal steroid use (13% and 53%, respectively), cesarean section (7% and 24%, respectively), and delivery room intubation (19% and 68%, respectively) increased markedly between 22 and 23 weeks. Infants at the lowest GAs were at greatest risk for morbidities. Overall, 93% had respiratory distress syndrome, 46% patent ductus arteriosus, 16% severe intraventricular hemorrhage, 11% necrotizing enterocolitis, and 36% late-onset sepsis. The new severity-based definition of bronchopulmonary dysplasia classified more infants as having bronchopulmonary dysplasia than did the traditional definition of supplemental oxygen use at 36 weeks (68%, compared with 42%). More than one-half of infants with extremely low GAs had undetermined retinopathy status at the time of discharge. Center differences in management and outcomes were identified. CONCLUSION Although the majority of infants with GAs of >or=24 weeks survive, high rates of morbidity among survivors continue to be observed.

Abstract
BACKGROUND The outcome of preterm neonates has been varied in different hospitals and regions in developing countries. This study aimed to determine the mortality, morbidity and survival of neonates weighing 1500 g or less and with gestational age of 30 weeks or less who were admitted to referral neonatal intensive care units (NICUs) of two hospitals in Isfahan city, Iran and to investigate the effect of birth weight, gestational age and Apgar score on infant mortality. METHODS We studied retrospectively the morbidity, mortality and survival of 194 newborns with a birth weight of </=1500 g and a gestational age of </=30 weeks who had been hospitalized during a 15-month period in NICUs of the two referral hospitals. The Kaplan-Meier method was used to estimate the survival of the neonates. The survival was defined as the discharge of live infant from the hospital within 75 days. RESULTS Overall, 125 (64.4%; 95%CI 58%-71%) of the 194 infants died during their hospital stay. The morbidity in this study was as follows: respiratory distress syndrome 76% (95%CI 70%-82%), septicemia 30.9% (95%CI 24%-37%), bronchopulmonary dysplasia 10.3% (95%CI 6%-15%), necrotizing enterocolitis 6.7% (95%CI 3%-10%), patent ductus arteriosus 12.4% (95%CI 8%-17%), intraventricular hemorrhage 7.2% (95%CI 4%-11%), and apnea 16.5% (95%CI 11%-22%). Packed cell transfusion was required in 43.3% (95%CI 36%-50%) of the neonates. The Kaplan Meier survival analysis revealed that 75% of the infants would live past 2 days, 50% after 14 days, and 25% after 69 days. CONCLUSIONS Even with modern perinatal technology and care, early deaths of very low birth weight infants are still common in our referral hospitals. The outcome of infants born at 24-28 weeks is unfavorable. The hospital level is an important factor affecting the mortality and morbidity of these infants.

Abstract
OBJECTIVES Postnatal survival rates of very low birth weight (VLBW) infants are well established for each birth weight or gestational age category. These figures do not differentiate viable infants who survive the first few days of life from extremely immature ones who die shortly after birth. This study aimed to develop standardized curves for day-by-day postnatal survival rates of VLBW infants. METHODS National Inpatient Sample Database and its pediatrics-only subportion were analyzed for the years 1997-2004. Infants with birth weight <1500 g were included in the study. Infants were classified according to their birth weight into 4 groups: <500, 500 to 749, 750 to 999, and 1000 to 1499 g. Postnatal survival rates were calculated for each group at birth and at 1, 2, 3, 4 to 5, 6 to 7, 14, 21, 28, and >28 postnatal days. RESULTS Overall survival for infants with birth weight <500 g was 8%. Those who lived through the first 3 days of life had a chance of survival up to 50%. Infants in the 500- to 749-g group had overall survival rate of 50% that increased to 70% if they survived through the third day and 80% by the end of the first week. There was no improvement in the overall survival of any birth weight category over the years of the study. CONCLUSIONS VLBW infants who survive the first few postnatal days have a considerably better chance for life. We can predict postnatal survival chances for each birth weight category on a day-by-day basis until discharge.

Abstract
OBJECTIVE To explore the incidence and analyze the high risk factors of PIVH in premature infants in mainland China. MATERIALS AND METHODS A total of 1122 premature infants at <37 weeks gestation were enrolled in this study. All the infants received intracranial ultrasound examinations within 1 week after birth, and the perinatal data were recorded to analyze the high risk factors for PIVH. RESULTS The results showed that the incidence rate of PIVH was 55.2% in mainland Chinese population. Among these cases, mild degrees of PIVH accounted for 82.2% and severe degrees of PIVH accounted for only 17.8%. The most important risk factors related to PIVH were low gestational age, low birth weight, low Apgar score and ventilatory treatment, etc. CONCLUSIONS It suggested that there were many high risk factors related to PIVH in premature infants and a screening cutoff point of 2000 g appeared to be more adequate for China.

Abstract
UNLABELLED Even though ventilatory support for preterm infants has improved over the past few decades, about 30% of intubated preterm infants fail an extubation attempt. There are still no simple standards to determine the optimal extubation time for those infants. OBJECTIVE To identify factors related to extubation success or failure in preterm infants less than 32 weeks of gestation (WG). POPULATION AND METHODS Retrospective study including 162 newborns less than 32 WG, requiring mechanical ventilation within the first 24h of life. Successful extubation was defined as no need for reintubation for any reason at least 7 days after the first extubation attempt. RESULTS Forty-one infants failed extubation (25.3%); 149 infants (92%) had mechanical ventilation in their first 30min of life. These infants had a lower gestational age (p<0.001) and a lower birth weight (p=0.003). They required a higher FiO(2) (p<0.001) and maximum inspiratory pressure (p=0.002). The infants who failed extubation had a lower pH (p=0.001) and hematocrit (p=0.032), and a higher PCO(2) (p=0.003). CONCLUSION As previously described, a low gestational age is a major factor predicting the extubation failure. However, our data suggests that ventilator settings and blood gas should also be considered when attempting extubation, following written guidelines.

Abstract
OBJECTIVE The goal was to identify, among extremely low birth weight (<or=1000 g) live births, the proportion of infants who were unimpaired at 18 to 22 months of corrected age. METHODS Unimpaired outcome was defined as Bayley Scales of Infant Development II scores of >or=85, normal neurologic examination findings, and normal vision, hearing, swallowing, and walking. Outcomes were determined for 5250 (86%) of 6090 extremely low birth weight inborn infants. RESULTS Of the 5250 infants whose outcomes were known at 18 months, 850 (16%) were unimpaired, 1153 (22%) had mild impairments, 1147 (22%) had moderate/severe neurodevelopmental impairments, and 2100 (40%) had died. Unimpaired survival rates varied according to birth weight, from <1% for infants <or=500 g to 24% for infants 901 to 1000 g. The regression model to predict unimpaired survival versus death or impairment for live births (N = 5250) indicated that 25.3% of the variance was derived from infant factors present at birth, including female gender, higher birth weight, singleton birth. The regression model to predict unimpaired survival for discharged infants indicated that most of the variance was derived from combined effects of major neonatal morbidities, neonatal interventions, and maternal demographic features (15.7%) and only 8.5% was derived from infant factors present at birth. CONCLUSIONS Although <1% of live-born infants of <or=500 g survive free of impairment at 18 months, this increases to almost 24% for infants of 901 to 1000 g. Female gender, singleton birth, higher birth weight, absence of neonatal morbidities, private health insurance, and white race increase the likelihood of unimpaired status.

Abstract
OBJECTIVE To describe the maturation of physiologic milestones in preterm infants born between 24 and 32 weeks' gestational age. METHODS We abstracted daily physiologic maturity information on 865 infants born at < or =32 weeks' gestation in the Northern California Kaiser Permanente Medical Care Program between 1998 and 2001. Data included ventilator and incubator settings, body temperature, apnea and bradycardia spells, use of methylxanthines, feeding method, and requirements for intravenous fluids. Multivariable quantile regression models identified risk factors associated with longer postmenstrual age to achieve various physiologic milestones, including time to full oral feeding, time to wean from supplemental heat, the last day with an apnea or bradycardia episode, the last day on methylxanthine medications, and the last day on supplemental oxygen. RESULTS Most milestones were achieved between 34 and 36 weeks' postmenstrual age, although there were wide variations between patients. In most cases, feeding and oxygen milestones were achieved last. For each milestone there was a monotonic relationship between birth gestational age and the median achievement postmenstrual age. However, bronchopulmonary dysplasia and necrotizing enterocolitis strongly influenced these results in infants of younger gestational age. CONCLUSIONS This study provides epidemiologic data describing the achievement of basic physiologic milestones that influence the discharge of a premature infant. This work serves as an additional contribution in the development of algorithms to monitor the progress of neonates through their initial hospitalization and provides a reference population for future interventions to improve the physiologic maturation of prematurely born infants.

Abstract
BACKGROUND An increased incidence of necrotizing enterocolitis (NEC) has been noted in infants who are born to mothers with chorioamnionitis. HYPOTHESIS Our objective was to test the hypothesis that newborn rat pups born to mothers exposed to prenatal lipopolysaccharide during pregnancy would be more susceptible to intestinal injury in a rat model of NEC and that the increased intestinal injury is mediated by dysregulation of inducible nitric oxide synthase. METHODS Time-dated pregnant Sprague-Dawley dams were given an intraperitoneal injection of either 2 mg/kg of lipopolysaccharide or vehicle. Rat pups from each group of dams were delivered at term and placed in a rat NEC model. A subset of pups was given either vehicle or aminoguanidine. Intestines were harvested and graded for degree of intestinal injury. RESULTS Maternal prenatal lipopolysaccharide exposure increased the frequency and severity of intestinal injury in the neonatal rat NEC model. Treatment with aminoguanidine significantly decreased plasma nitric oxide levels. Additionally, aminoguanidine significantly decreased intestinal injury. CONCLUSIONS Intestinal injury observed may be mediated via nitric oxide synthase dysregulation.

Developmental changes in the responses of preterm infants to a painful stressor. Infant Behav Dev 2008; 31:614-23.

Abstract
The purpose of this investigation was to examine longitudinally gestational age and developmental differences in preterm infants' self-regulatory abilities in response to a painful stressor, as well as associations between behavioral and cardiovascular responses. Participants included 49 healthy premature infants. Behavioral and cardiovascular responses to a heel stick blood draw were compared between infants of 28-31 and 32-34 weeks' gestation age at birth. Both gestational age groups displayed behavioral and cardiovascular indications of stress in response to the blood draw. However, both shortly after birth and several weeks later, infants born at younger gestational ages (28-31 weeks) were more physiologically reactive. Evidence that the behavioral stress responses of 28-31 weeks' gestation age group preterm infants do not reflect their physiological responses suggests that evaluation of preterm infants' experiences and risk require assessments of both physiology and behavior. The greater stress vulnerability of the 28-31 weeks' gestation group relative to the 32-34 weeks' gestation group and the implications of this for subsequent development are discussed.

Abstract
BACKGROUND The majority of children born with very low birth weight (VLBW; < 1500g) enter mainstream schools. They experience significant neurodevelopmental disabilities during childhood. The specific aims of our study were to evaluate the neonatal outcomes of VLBW infants and whether they would influence intelligence quotient (IQ), cognitive function and learning disabilities at the age of 6 or 8 years. METHODS We enrolled VLBW neonates who weighed less than 1500g and who were delivered at Shin-Kong Wu Ho-Su Memorial Hospital in 1996 and 1999. The psychological assessments were applied with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) for age 6 and Wechsler Intelligence Scale for Children-Third Edition (WISC-III) for age 8. We recorded their demographic data, ventilation duration by days, length of stay, use of surfactant, respiratory distress syndrome (RDS), and other complications. RESULTS According to whether the full scale intelligence quotient (FSIQ) was above or below the average score (FSIQ = 90), we divided VLBW children into two groups (< 90, n = 17; > or = 90, n = 21). The children with lower gestational age had lower FSIQ (p = 0.013). The higher FSIQ group (> or = 90) showed more prenatal steroid use (5/17, 29.4% vs. 14/21, 66.7%; p = 0.049). There were more boys in the lower FSIQ group (< 90, 13/17, 76.5% vs. > or = 90, 7/21, 33.3%; p = 0.011). The average IQ scores were 78.11 +/- 9.05 and 102.57 +/- 8.89 in the FSIQ < 90 and FSIQ > or = 90 groups, respectively. The groups were similar in ventilation duration by days, use of surfactant, frequency of sepsis, RDS, bronchopulmonary dysplasia, patent ductus arteriosus, intraventricular hemorrhage and retinopathy of prematurity. CONCLUSION In our study, the children with lower gestational age had lower FSIQ. There was no significant association between small for gestational age and IQ performance. The neonatal outcomes of VLBW infants did have less impact on IQ performance later in life.

Abstract
An increasing number of studies have examined the development of walking in preterm infants; however, the results concerning those who had no major neonatal disease were inconclusive. This study was therefore aimed to examine the age of onset, the quality of early walking movement, and the sensitivity to resonant period of the force-driven harmonic oscillator (FDHO) model in preterm infants who had no major neonatal disease and normal term infants. Twenty-nine preterm infants and 29 term infants were prospectively examined for their age of onset of independent walking and were subsequently assessed the qualitative features of walking at 18 months of corrected age using kinematic analysis. Kinematic variables examined included spatio-temporal organization, inter-joint coordination, and inter-limb coordination. The anthropometric data were used to calculate the resonant period. The results demonstrated that the preterm infants attained independent walking at significantly older ages than the term infants when corrected for prematurity. The preterm infants manifested similar walking characteristics, except for shorter stride lengths, at 18 months of corrected age compared with the term infants. Furthermore, the stride periods of both groups were accurately predicted by the resonant period of the FDHO model. We conclude that preterm birth without accompanied major neonatal disease may affect infants' age of onset and spatial organization but not their sensitivity to resonance during the early stage of walking development.

Abstract
OBJETIVO: Avaliar o valor prognóstico da distensão de alças intestinais observada em radiografias na evolução e mortalidade de neonatos com enterocolite necrosante. MATERIAIS E MÉTODOS: Nas radiografias de abdome de 53 pacientes obtidas no momento da suspeita diagnóstica de enterocolite necrosante, foi realizada a medida do diâmetro da alça mais distendida (AD), assim como a distância entre a borda superior da primeira vértebra lombar e a borda inferior da segunda (L1-L2), a distância entre as bordas laterais dos pedículos da primeira vértebra lombar (L1), e foram estabelecidas as associações entre AD/L1-L2 e AD/L1. Esta medida foi considerada como possível determinante de potenciais complicações, intervenção cirúrgica e mortalidade. RESULTADOS: Os pacientes que necessitaram de tratamento cirúrgico, aqueles que tiveram complicações durante a evolução e aqueles que morreram da doença tiveram a relação entre AD e AD/L1-L2 maiores (p < 0,05). Os valores de AD/L1 e a localização da alça mais distendida não foram diferentes nos grupos com evolução desfavorável. CONCLUSÃO: Distensão de alça intestinal detectada em radiografias de abdome realizadas na admissão sugerem pior prognóstico em enterocolite necrosante. Outrossim, medidas do diâmetro da alça mais distendida nessas radiografias são um método simples e reprodutível que oferece informações diagnósticas e prognósticas.
