Abstract
OBJECTIVE To investigate whether extrauterine growth restriction (EUGR) during the neonatal hospitalisation by sex among extremely preterm (EPT) infants is associated with cerebral palsy (CP) and cognitive and motor abilities at 5 years of age. STUDY DESIGN Population-based cohort of births <28 weeks of gestation with data from obstetric and neonatal records and parental questionnaires and clinical assessments at 5 years of age. SETTING 11 European countries. PATIENTS 957 EPT infants born in 2011-2012. MAIN OUTCOMES EUGR at discharge from the neonatal unit was defined as (1) the difference between Z-scores at birth and discharge with <-2 SD as severe, -2 to -1 SD as moderate using Fenton's growth charts (Fenton) and (2) average weight-gain velocity using Patel's formula in grams (g) per kilogram per day (Patel) with <11.2 g (first quartile) as severe, 11.2-12.5 g (median) as moderate. Five-year outcomes were: a CP diagnosis, intelligence quotient (IQ) using the Wechsler Preschool and Primary Scales of Intelligence tests and motor function using the Movement Assessment Battery for Children, second edition. RESULTS 40.1% and 33.9% children were classified as having moderate and severe EUGR, respectively, by Fenton and 23.8% and 26.3% by Patel. Among children without CP, those with severe EUGR had lower IQ than children without EUGR (-3.9 points, 95% Confidence Interval (CI)=-7.2 to -0.6 for Fenton and -5.0 points, 95% CI=-8.2 to -1.8 for Patel), with no interaction by sex. No significant associations were observed between motor function and CP. CONCLUSIONS Severe EUGR among EPT infants was associated with decreased IQ at 5 years of age.

Using Digital Tools to Study the Health of Adults Born Preterm at a Large Scale: e-Cohort Pilot Study. J Med Internet Res 2023; 25:e39854. [PMID: 37184902 DOI: 10.2196/39854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 01/20/2023] [Accepted: 02/24/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND Preterm birth is a global health concern. Its adverse consequences may persist throughout the life course, exerting a potentially heavy burden on families, health systems, and societies. In high-income countries, the first children who benefited from improved care are now adults entering middle age. However, there is a clear gap in the knowledge regarding the long-term outcomes of individuals born preterm. OBJECTIVE This study aimed to assess the feasibility of recruiting and following up an e-cohort of adults born preterm worldwide and provide estimations of participation, characteristics of participants, the acceptability of questions, and the quality of data collected. METHODS We implemented a prospective, open, observational, and international e-cohort pilot study (Health of Adult People Born Preterm-an e-Cohort Pilot Study [HAPP-e]). Inclusion criteria were being an adult (aged ≥18 years), born preterm (<37 weeks of gestation), having internet access and an email address, and understanding at least 1 of the available languages. A large, multifaceted, and multilingual communication strategy was established. Between December 2019 and June 2021, inclusion and repeated data collection were performed using a secured web platform. We provided descriptive statistics regarding participation in the e-cohort, namely, the number of persons who registered on the platform, signed the consent form, initiated and completed the baseline questionnaire, and initiated and completed the follow-up questionnaire. We also described the main characteristics of the HAPP-e participants and provided an assessment of the quality of the data and the acceptability of sensitive questions. RESULTS As of December 31, 2020, a total of 1004 persons had registered on the platform, leading to 527 accounts with a confirmed email and 333 signed consent forms. A total of 333 participants initiated the baseline questionnaire. All participants were invited to follow-up, and 35.7% (119/333) consented to participate, of whom 97.5% (116/119) initiated the follow-up questionnaire. Completion rates were very high both at baseline (296/333, 88.9%) and at follow-up (112/116, 96.6%). This sample of adults born preterm in 34 countries covered a wide range of sociodemographic and health characteristics. The gestational age at birth ranged from 23+6 to 36+6 weeks (median 32, IQR 29-35 weeks). Only 2.1% (7/333) of the participants had previously participated in a cohort of individuals born preterm. Women (252/333, 75.7%) and highly educated participants (235/327, 71.9%) were also overrepresented. Good quality data were collected thanks to validation controls implemented on the web platform. The acceptability of potentially sensitive questions was excellent, as very few participants chose the "I prefer not to say" option when available. CONCLUSIONS Although we identified room for improvement in specific procedures, this pilot study confirmed the great potential for recruiting a large and diverse sample of adults born preterm worldwide, thereby advancing research on adults born preterm.

Abstract
To estimate the relationship among the cesarean delivery (CD), mortality and morbidity in very low birth weight (VLBW) infants weighing less than 1500 g. This retrospective cohort study enrolled 242 VLBW infants delivered between the 24 to 31week of gestation from 2015 to 2021. We compared CD with vaginal delivery (VD). The primary outcome was a composite neonatal morbidity including bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, late-onset sepsis and retinopathy of prematurity. The secondary outcome included mortality within 28 days. A multivariate logistic regression was used and adjusted for birthweight, twin pregnancy and antenatal steroids intake. The overall CD rate was 80.6%. Compared with VD, a significantly lower composite neonatal morbidity was associated with CD (adjusted odds ratio, 0.33, 95% confidence interval, 0.12-0.90, P = .031). The relationship between CD and neonatal morbidity disappeared when the VLBW infants were stratified according to the gestational age. No significant difference was observed between the VD and CD cohorts regarding mortality. Compared with VD, CD was associated with a lower morbidity in VLBW infants. Further studies are required to clarify how this association is influenced by gestational age.

Abstract
AIM Organisation of care, perinatal and neonatal management of very preterm infants in the Nordic regions were hypothesised to vary significantly. The aim of this observational study was to test this hypothesis. METHODS Information on preterm infants in the 21 greater healthcare regions of Denmark, Finland, Iceland, Norway and Sweden was gathered from national registers in 2021. Preterm birth rates, case-mix, perinatal interventions, neonatal morbidity and survival to hospital discharge in very (<32 weeks) and extremely preterm infants (<28 weeks of gestational age) were compared. RESULTS Out of 287 642 infants born alive, 16 567 (5.8%) were preterm, 2389 (0.83%) very preterm and 800 (0.28%) were extremely preterm. In very preterm infants, exposure to antenatal corticosteroids varied from 85% to 98%, live births occurring at regional centres from 48% to 100%, surfactant treatment from 28% to 69% and use of mechanical ventilation varied from 13% to 77% (p < 0.05 for all comparisons). Significant regional variations within and between countries were also seen in capacity in neonatal care, case-mix and number of admissions, whereas there were no statistically significant differences in survival or major neonatal morbidities. CONCLUSION Management of very preterm infants exhibited significant regional variations in the Nordic countries.

GYNECOLOGIE, OBSTETRIQUE, FERTILITE & SENOLOGIE 2023; 51:166-171. [PMID: 36372155 DOI: 10.1016/j.gofs.2022.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 10/31/2022] [Accepted: 11/01/2022] [Indexed: 11/13/2022]
Abstract
INTRODUCTION Fetal growth restriction (FGR) is an obstetric complication responsible for increased perinatal morbidity and mortality. In some severe and early FGR situations, termination of pregnancy (TOP) may be considered. The main objective of our study was to describe the population of fetuses for whom a TOP was performed for isolated FGR beyond 24 days' gestation and for a birth weight>450g and to analyze the immediate outcome, at 2 and 5 years, of term- and weight-matched neonates born in a context of severe FGR after 24 weeks' gestation and over 450g. MATERIAL AND METHODS We conducted an observational, descriptive, retrospective, uni-centric study between 2008 and 2018. The primary endpoint was survival at maternity discharge, 2 years and 5 years in these children. Secondary endpoints were assessment of immediate and longer-term postnatal morbidity. Twenty-five patients (36%) were selected for the study with a fetus weight>450g and term>24 weeks. Each fetus with an TOP was matched (on gestational age and weight) with two live-born children from the perinatal network cohort to assess immediate discharge outcome, and then at 2 and 5 years. RESULTS The mortality rate was 24%. In neonatal management, for 67% (n=17) of the newborns the evolution was complicated by death or at least two sequelae (bronchopulmonary dysplasia, hyaline membrane disease stage≥2, intraventricular of grade 3 and 4, ulcerative colitis requiring surgery, retinopathy of prematurity stage 2 and more) at discharge. In 32% (n=8) of cases, there was at least one sequela at discharge. Regardless of gestational age at birth, development at 2 years was normal for 48% (n=11/23) of them and abnormal for 22% (n=5) and development at 5 years was normal for 56% (n=9/16) of them and abnormal for 19% (n=5). CONCLUSION An ultrasound evaluation in a reference center as well as additional information by the obstetrician and neonatologist ensures the most appropriate informed involvement of the couple in the medical decisions before and after birth.

Risk factors for cerebral palsy and movement difficulties in 5-year-old children born extremely preterm. Pediatr Res 2023:10.1038/s41390-022-02437-6. [PMID: 36694025 DOI: 10.1038/s41390-022-02437-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 11/10/2022] [Accepted: 11/19/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND Motor impairment is common after extremely preterm (EPT, <28 weeks' gestational age (GA)) birth, with cerebral palsy (CP) affecting about 10% of children and non-CP movement difficulties (MD) up to 50%. This study investigated the sociodemographic, perinatal and neonatal risk factors for CP and non-CP MD. METHODS Data come from a European population-based cohort of children born EPT in 2011-2012 in 11 countries. We used multinomial logistic regression to assess risk factors for CP and non-CP MD (Movement Assessment Battery for Children - 2nd edition ≤5th percentile) compared to no MD (>15th percentile) among 5-year-old children. RESULTS Compared to children without MD (n = 366), young maternal age, male sex and bronchopulmonary dysplasia were similarly associated with CP (n = 100) and non-CP MD (n = 224) with relative risk ratios (RRR) ranging from 2.3 to 3.6. CP was strongly related to severe brain lesions (RRR >10), other neonatal morbidities, congenital anomalies and low Apgar score (RRR: 2.4-3.3), while non-CP MD was associated with primiparity, maternal education, small for GA (RRR: 1.6-2.6) and severe brain lesions, but at a much lower order of magnitude. CONCLUSION CP and non-CP MD have different risk factor profiles, with fewer clinical but more sociodemographic risk factors for non-CP MD. IMPACT Young maternal age, male sex and bronchopulmonary dysplasia similarly increased risks of both cerebral palsy and non-cerebral palsy movement difficulties. Cerebral palsy was strongly related to clinical risk factors including severe brain lesions and other neonatal morbidities, while non-cerebral palsy movement difficulties were more associated with sociodemographic risk factors. These results on the similarities and differences in risk profiles of children with cerebral palsy and non-cerebral palsy movement difficulties raise questions for etiological research and provide a basis for improving the identification of children who may benefit from follow-up and early intervention.

Abstract
BACKGROUND Preterm birth is a leading cause of infant mortality, particularly for those born extremely prematurely (EP; <28 weeks' gestational age [GA]). Survivors are predisposed to complications such as bronchopulmonary dysplasia (BPD), chronic lung disease (CLD), intraventricular hemorrhage (IVH), and retinopathy of prematurity (ROP). AIMS To examine the epidemiology, complications, and mortality/survival among EP infants. STUDY DESIGN Retrospective analysis of electronic medical records from the Kaiser Permanente Northern California database. SUBJECTS EP infants live-born between 22 and <28 weeks' GA from 1997 to 2016. OUTCOME MEASURES Cumulative all-cause mortality/survival were analyzed and stratified by GA (22 to <24, 24 to <26, 26 to <28 weeks), complications (BPD/CLD, IVH, ROP), and birth period (1997 to 2003, 2004 to 2009, 2010 to 2016). Cox proportional hazard models were constructed to assess the mortality risk associated with BPD/CLD or IVH. RESULTS 2154 EP infants were identified; of these, 916 deaths were recorded. Mortality was highest during the first 3 months (41.7 % cumulative mortality), and few were reported after 2 years (42.5 % cumulative mortality). Mortality decreased with higher GA and over more recent birth periods. BPD/CLD and IVH grade 3/4 were associated with increased mortality risk versus no complications (adjusted hazard ratios 1.41 and 1.78, respectively). CONCLUSIONS The risk of mortality is high during the first few months of life for EP infants, and is even higher for those with BPD and IVH. Despite an overall trend toward increased survival for EP infants, strategies targeting survival of EP infants with these complications are needed.

Abstract
BACKGROUND AND OBJECTIVES Children born extremely preterm (EPT), <28 weeks' gestational age, face higher risks of movement difficulties than their term-born peers. Studies report varying prevalence estimates and prognostic factors identifying children who could benefit from early intervention are inconsistent. This study investigated the prevalence of movement difficulties in children born EPT and associated risk factors. METHODS Data come from a population-based EPT birth cohort in 2011 and 2012 in 11 European countries. Children without cerebral palsy were assessed at 5 years of age (N = 772) with the Movement Assessment Battery for Children-Second Edition, which classifies movement difficulties as none (>15th percentile), at risk (6th-15th percentile) and significant (≤5th percentile). Associations with sociodemographic, perinatal, and neonatal characteristics collected from obstetric and neonatal medical records and parental questionnaires were estimated using multinomial logistic regression. RESULTS We found 23.2% (n = 179) of children were at risk for movement difficulties and 31.7% (n = 244) had significant movement difficulties. Lower gestational age, severe brain lesions, and receipt of postnatal corticosteroids were associated with significant movement difficulties, whereas male sex and bronchopulmonary dysplasia were associated with being at risk and having significant movement difficulties. Children with younger, primiparous, less educated, and non-European-born mothers were more likely to have significant movement difficulties. Differences in prevalence between countries remained after population case-mix adjustments. CONCLUSIONS This study confirms a high prevalence of movement difficulties among EPT children without cerebral palsy, which are associated with perinatal and neonatal risk factors as well as sociodemographic characteristics and country.

Abstract
Background:
Prematurity is still a major cause of neonatal and infant mortality and morbidity.
Aim:
This study aimed to describe the incidence of preterm infants, indications of admission, risk factors, and discharge outcome.
Materials and Methods:
A retrospective, descriptive design was used. A sample of 692 preterm infants admitted to the Neonatal Intensive Care Unit (NICU) was included. A structured sheet was used to gather the necessary data. It involved two parts: characteristics of preterm infants and their mothers and risk factors concerning preterm birth.
Results:
The study found that 49.4% of admitted neonates were preterm; among them, 48.1% died on discharge. Moreover, there were significant relations between the type of gestation (p=0.000), mothers' age (p=0.001), anemia, pregnancy-induced hypertension, preeclampsia, antepartum hemorrhage, premature rupture of membranes, obstructed labor, family history of medical diseases, and mothers' history of medical diseases with preterm infants' gestational age (p=0.01, 0.001, 0.02, 0.01, 0.000, 0.000, 0.000, 0.000, respectively). Moreover, it was observed that higher admission of preterm infants who had respiratory problems, followed by gastrointestinal problems.
Conclusion:
There was a higher prevalence with a higher mortality rate of admitted preterm infants to NICU. Likewise, the type of gestation, mothers' age, presence of complications during pregnancy, bad obstetric history, and family and medical history of diseases were the most common risk factors of prematurity. Moreover, respiratory problems were the main etiology for admission of preterm infants to NICU. Therefore, early screening of diseases and obstetric complications during pregnancy is recommended.
Implications for Nursing Practice:
Providing educational programs for pediatric nurses will increase their level of awareness regarding incidence, indications, risk factors, and discharge outcome of prematurity, thus reducing the rate of mortality and morbidity among preterm infants.

Abstract
OBJECTIVES To compare mortality, morbidity and neurodevelopment by mode of delivery (MOD) for very preterm births with low prelabour risk of caesarean section (CS). METHODS The study was a population-based prospective cohort study in 19 regions in 11 European countries. Multivariable mixed effects models and weighted propensity score models were used to estimate adjusted odds ratios (aOR) by observed MOD and the unit's policy regarding MOD. Population: Singleton vertex-presenting live births at 24 + 0 to 31 + 6 weeks of gestation without serious congenital anomalies, preeclampsia, HELLP or eclampsia, antenatal detection of growth restriction and prelabour CS for fetal or maternal indications. RESULTS Main outcome measures: A composite of in-hospital mortality and intraventricular haemorrhage (grade III/IV) or periventricular leukomalacia. Secondary outcomes were components of the primary outcome, 5 min Apgar score <7 and moderate to severe neurodevelopmental impairment at two years of corrected age. The rate of CS was 29.6% but varied greatly between countries (8.0-52.6%). MOD was not associated with the primary outcome (aOR for CS 0.99; 95% confidence interval [CI] 0.65-1.50) when comparing units with a systematic policy of CS or no policy of MOD to units with a policy of vaginal delivery (aOR 0.88; 95% CI 0.59-1.32). No association was observed for two-year neurodevelopment impairment for CS (aOR 1.15; 95% CI 0.66-2.01) or unit policies (aOR 1.04; 95% CI 0.63-1.70). CONCLUSIONS Among singleton vertex-presenting live births without medical complications requiring a CS at 24 + 0 to 31 + 6 weeks of gestation, CS was not associated with improved neonatal or long-term outcomes.

Abstract
IMPORTANCE Extreme prematurity is associated with a substantial burden on health care systems worldwide. However, little is known about the prognosis of infants born extremely preterm in developing countries, such as China. OBJECTIVE To describe survival and major morbidity among infants born extremely preterm in China over the past decade. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study was conducted from January 1, 2010, through December 31, 2019. Included individuals were infants with gestational age less than 28 weeks discharged from 1 of 68 neonatal intensive care units located in 31 provinces in China. Data were analyzed from August through October 2020. EXPOSURE Extremely preterm birth. MAIN OUTCOMES AND MEASURES Survival to discharge and major morbidity (ie, bronchopulmonary dysplasia, grades III-IV intraventricular hemorrhage, white matter injury, stage II-III necrotizing enterocolitis, sepsis, or severe retinopathy of prematurity) were measured. RESULTS Among 8514 eligible infants, 5295 (62.2%) were male and 116 infants (2.0%) were small for gestational age (SGA). Overall, 5302 infants (62.3%) survived to discharge. The survival rate was 1 of 21 infants (4.8%) at 22 weeks, 13 of 71 infants (18.3%) at 23 weeks, 144 of 408 infants (35.3%) at 24 weeks, 480 of 987 infants (48.6%) at 25 weeks, 1423 of 2331 infants (61.0%) at 26 weeks, and 3241 of 4692 infants (69.1%) at 27 weeks. Survival increased from 136 of 241 infants (56.4%; 95% CI, 50.1%-62.7%) in 2010 to 1110 of 1633 infants (68.0%; 95% CI, 65.7%-70.2%) in 2019 for infants born at 24 to 27 weeks (mean difference, 11.5%; 95% CI, 4.9%-18.2%; P < .001), without a significant change for infants born at less than 24 weeks. Major morbidity was found in 5999 of 8281 infants overall, for a rate of 72.4%, which increased from 116 of 223 infants (52.0%; 95% CI, 45.4%-58.6%) to 1363 of 1656 infants (82.3%; 95% CI, 80.5%-84.1%) from 2010 to 2019 (mean difference, 30.3%; 95% CI, 23.5%-37.1%, P < .001). Regional variations in survival were identified, with an almost 2-fold increase (1.94-fold; 95% CI, 1.66-2.27; P < .001) from 188 of 474 infants (39.7%) in northwest China to 887 of 1153 infants (76.9%) in north China. Gestational age (adjusted risk ratio [aRR], 1.084; 95% CI, 1.063-1.105; P < .001), birth weight (aRR, 1.028; 95% CI, 1.020-1.036; P < .001), premature rupture of membranes (aRR, 1.025; 95% CI, 1.002-1.048; P = .03), and antenatal steroids (aRR, 1.029; 95% CI, 1.004-1.055; P = .02) were associated with improved survival, while being born SGA (aRR, 0.801; 95% CI, 0.679-0.945; P = .01), being male (aRR, 0.975; 95% CI, 0.954-0.997; P = .02), multiple birth (aRR, 0.955; 95% CI, 0.929-0.982; P = .001), having a mother with gestational diabetes (aRR, 0.946; 95% CI, 0.913-0.981; P = .002), and low Apgar score (aRR, 0.951; 95% CI, 0.925-0.977; P < .001) were found to be risk factors associated with decreased chances of survival. CONCLUSIONS AND RELEVANCE This study found that infants born extremely preterm were at increased risk of mortality and morbidity in China, with a survival rate that improved over time and a major morbidity rate that increased. These findings suggest that more active and effective treatment strategies are needed, especially for infants born at gestational age 25 to 27 weeks.

Abstract
OBJECTIVE Extrauterine growth restriction (EUGR) among very preterm infants is related to poor neurodevelopment, but lack of consensus on EUGR measurement constrains international research. Our aim was to compare EUGR prevalence in a European very preterm cohort using commonly used measures. DESIGN Population-based observational study. SETTING 19 regions in 11 European countries. PATIENTS 6792 very preterm infants born before 32 weeks' gestational age (GA) surviving to discharge. MAIN OUTCOME MEASURES We investigated two measures based on discharge-weight percentiles with (1) Fenton and (2) Intergrowth (IG) charts and two based on growth velocity (1) birth weight and discharge-weight Z-score differences using Fenton charts and (2) weight-gain velocity using Patel's model. We estimated country-level relative risks of EUGR adjusting for maternal and neonatal characteristics and associations with population differences in healthy newborn size, measured by mean national birth weight at 40 weeks' GA. RESULTS About twofold differences in EUGR prevalence were observed between countries for all indicators and these persisted after case-mix adjustment. Discharge weight <10th percentile using Fenton charts varied from 24% (Sweden) to 60% (Portugal) and using IG from 13% (Sweden) to 43% (Portugal), while low weight-gain velocity ranged from 35% (Germany) to 62% (UK). Mean term birth weight strongly correlated with both percentile-based measures (Spearman's rho=-0.90 Fenton, -0.84 IG, p<0.01), but not Patel's weight-gain velocity (rho: -0.38, p=0.25). CONCLUSIONS Very preterm infants have a high prevalence of EUGR, with wide variations between countries in Europe. Variability associated with mean term birth weight when using common postnatal growth charts complicates international benchmarking.

Abstract
Background: As childbearing is postponed in developed countries, maternal age (MA) has increased over decades with an increasing number of pregnancies between age 35-39 and beyond. The aim of the study was to determine the influence of advanced (AMA) and very advanced maternal age (vAMA) on morbidity and mortality of very preterm (VPT) infants. Methods: This was a population-based cohort study including infants from the "Effective Perinatal Intensive Care in Europe" (EPICE) cohort. The EPICE database contains data of 10329 VPT infants of 8,928 mothers, including stillbirths and terminations of pregnancy. Births occurred in 19 regions in 11 European countries. The study included 7,607 live born infants without severe congenital anomalies. The principal exposure variable was MA at delivery. Infants were divided into three groups [reference 18-34 years, AMA 35-39 years and very(v) AMA ≥40 years]. Infant mortality was defined as in-hospital death before discharge home or into long-term pediatric care. The secondary outcome included a composite of mortality and/or any one of the following major neonatal morbidities: (1) moderate-to-severe bronchopulmonary dysplasia; (2) severe brain injury defined as intraventricular hemorrhage and/or cystic periventricular leukomalacia; (3) severe retinopathy of prematurity; and (4) severe necrotizing enterocolitis. Results: There was no significant difference between MA groups regarding the use of surfactant therapy, postnatal corticosteroids, rate of neonatal sepsis or PDA that needed pharmacological or surgical intervention. Infants of AMA/vAMA mothers required significantly less mechanical ventilation during NICU stay than infants born to non-AMA mothers, but there was no significant difference in length of mechanical ventilation and after stratification by gestational age group. Adverse neonatal outcomes in VPT infants born to AMA/vAMA mothers did not differ from infants born to mothers below the age of 35. Maternal age showed no influence on mortality in live-born VPT infants. Conclusion: Although AMA/vAMA mothers encountered greater pregnancy risk, the mortality and morbidity of VPT infants was independent of maternal age.

Abstract
Stillbirth definitions vary between countries around the globe. The purpose of this paper was to explore stillbirth definitions used by high income countries around the world, specifically compared to Ireland, their stillbirth and mortality rates and to examine how these rates are influenced by standards of care, especially resuscitation efforts within the delivery room for very preterm infants. A literature review was performed using PubMed, Academic Search Complete, MEDLINE, and CINAHL. These databases were searched with the terms "(stillbirth OR still birth OR stillborn) AND (definition OR registration OR registry)" and "(fetal OR neonatal OR neonate) AND Viability AND Gestational Age" in two separate searches. The database searches returned 1081 results involving stillbirths and 164 results for neonatal viability. After title, abstract, full text review, and reference review 33 papers remained for use in this study. Within the European Union (EU), 59.2 % (n = 16), 14.8 % (n = 4), 11.1 % (n = 3), and 3.7 % (n = 1) countries classify stillbirths at gestational ages of ≥22 weeks, ≥24 weeks, ≥28 weeks, and ≥180 gestational days respectively. The median stillbirth rate in Europe using ≥28 weeks gestational age as a cut-off was 2.7 per 1000 births, but this increased to 3.3 per 1000 births when stillbirths from 24 to 27 weeks gestation were included. Of the thirteen countries whose mortality data was examined, survival rates for liveborn infants ranged from 0-37.3 %, 1.1-64.5 %, 31.0-77.7 %, and 59.1-85.7 % for the gestational ages of 22, 23, 24, and 25 weeks, respectively. In 1995, survival rates for the United Kingdom and Ireland were only 26 % for those born at 24 weeks gestation, however this has almost doubled in Ireland to 56.6 % in 2014-2017. Survival rates have improved to the point that, in 2014-2017, the survival rate of infants born at 23 weeks gestation (32.3 %) was 6 % higher than the rate for those born at 24 weeks gestation in 1995. Due to the improvement in survival rates, multiple international organisations recommend recording stillbirths from 22 weeks gestation and/or 500 g. Based on the findings from this review, and due to improving survival rates for periviable infants, it is recommended the stillbirth definition in Ireland should be updated to ≥22 weeks' gestation and ≥400 g to comply with improved medical developments.

Low socio-economic conditions and prematurity-related morbidities explain healthcare use and costs for 2-year-old very preterm children. Acta Paediatr 2020; 109:1791-1800. [PMID: 31977107 DOI: 10.1111/apa.15183] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Revised: 01/14/2020] [Accepted: 01/20/2020] [Indexed: 12/29/2022]
Abstract
AIM To estimate healthcare use and related costs for 2-year-old very preterm (VP) children after discharge from the neonatal unit. METHODS As part of a European project, we recruited an area-based cohort including all VP infants born in three Italian regions (Lazio, Emilia-Romagna and Marche) in 2011-2012. At 2 years corrected age, parents completed a questionnaire on their child health and healthcare use (N = 732, response rate 75.6%). Cost values were assigned based on national reimbursement tariffs. We used multivariable analyses to identify factors associated with any rehospitalisation and overall healthcare costs. RESULTS The most frequently consulted physicians were the paediatrician (85% of children), the ophthalmologist (36%) and the neurologist/neuropsychiatrist (26%); 38% of children were hospitalised at least once after the initial discharge, for a total of 513 admissions and over one million euros cost, corresponding to 75% of total healthcare costs. Low maternal education and parental occupation index, congenital anomalies and postnatal prematurity-related morbidities significantly increased the risk of rehospitalisation and total healthcare costs. CONCLUSION Rehospitalisation and outpatient care are frequent in VP children, confirming a substantial health and economic burden. These findings should inform the allocation of resources to preventive and rehabilitation services for these children.

Abstract
Background Preterm birth is a worldwide epidemic and a leading cause of neonatal mortality. In this study, we aimed to evaluate the incidence, risk factors and consequences of preterm birth in Nepal. Methods This was an observational study conducted in 12 public hospitals of Nepal. All the babies born during the study period were included in the study. Babies born < 37 weeks of gestation were classified as preterm births. For the association and outcomes for preterm birth, univariate followed by multiple regression analysis was conducted. Results The incidence of preterm was found to be 93 per 1000 live births. Mothers aged less than 20 years (aOR 1.26;1.15–1.39) had a high risk for preterm birth. Similarly, education of the mother was a significant predictor for preterm birth: illiterate mothers (aOR 1.41; 1.22–1.64), literate mothers (aOR 1.21; 1.08–1.35) and mothers having basic level of education (aOR 1.17; 1.07–1.27). Socio-demographic factors such as smoking (aOR 1.13; 1.01–1.26), use of polluted fuel (aOR 1.26; 1.17–1.35) and sex of baby (aOR 1.18; 1.11–1.26); obstetric factors such as nulliparity (aOR 1.33; 1.20–1.48), multiple delivery (aOR 6.63; 5.16–8.52), severe anemia during pregnancy (aOR 3.27; 2.21–4.84), antenatal visit during second trimester (aOR 1.13; 1.05–1.22) and third trimester (aOR 1.24; 1.12–1.38), < 4 antenatal visits during pregnancy (aOR 1.49; 1.38–1.61) were found to be significant risk factors of preterm birth. Preterm has a risk for pre-discharge mortality (10.60; 9.28–12.10). Conclusion In this study, we found high incidence of preterm birth. Various socio-demographic, obstetric and neonatal risk factors were associated with preterm birth. Risk factor modifications and timely interventions will help in the reduction of preterm births and associated mortalities. Trial registration ISRCTN30829654.

Abstract
OBJECTIVE To determine whether the variation in neurodevelopmental disability rates between populations persists after adjustment for demographic, maternal and infant characteristics for an international very preterm (VPT) birth cohort using a standardised approach to neurodevelopmental assessment at 2 years of age. DESIGN Prospective standardised cohort study. SETTING 15 regions in 10 European countries. PATIENTS VPT births: 22+0-31+6 weeks of gestation. DATA COLLECTION Standardised data collection tools relating to pregnancy, birth and neonatal care and developmental outcomes at 2 years corrected age using a validated parent completed questionnaire. MAIN OUTCOME MEASURES Crude and standardised prevalence ratios calculated to compare rates of moderate to severe neurodevelopmental impairment between regions grouped by country using fixed effects models. RESULTS Parent reported rates of moderate or severe neurodevelopmental impairment for the cohort were: 17.3% (ranging 10.2%-26.1% between regions grouped by country) with crude standardised prevalence ratios ranging from 0.60 to 1.53. Adjustment for population, maternal and infant factors resulted in a small reduction in the overall variation (ranging from 0.65 to 1.30). CONCLUSION There is wide variation in the rates of moderate to severe neurodevelopmental impairment for VPT cohorts across Europe, much of which persists following adjustment for known population, maternal and infant factors. Further work is needed to investigate whether other factors including quality of care and evidence-based practice have an effect on neurodevelopmental outcomes for these children.

Unit policies regarding tocolysis after preterm premature rupture of membranes: association with latency, neonatal and 2-year outcomes (EPICE cohort). Sci Rep 2020; 10:9535. [PMID: 32533019 PMCID: PMC7293322 DOI: 10.1038/s41598-020-65201-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Accepted: 04/29/2020] [Indexed: 11/09/2022] Open
Abstract
After preterm premature rupture of membranes (PPROM), antibiotics and antenatal steroids are effective evidence-based interventions, but the use of tocolysis is controversial. We investigated whether a unit policy of tocolysis use after PPROM is associated with prolonged gestation and improved outcomes for very preterm infants in units that systematically use these other evidence-based treatments. From the prospective, observational, population-based EPICE cohort study (all very preterm births in 19 regions from 11 European countries, 2011-2012), we included 607 women with a singleton pregnancy and PPROM at 24-29 weeks' gestation, of whom 101, 195 and 311 were respectively managed in 17, 32 and 45 units with no-use, restricted and liberal tocolysis policies for PPROM. The association between unit policies and outcomes (early-onset sepsis, survival at discharge, survival at discharge without severe morbidity and survival at two years without gross motor impairment) was investigated using three-level random-intercept logistic regression models, showing no differences in neonatal or two-year outcomes by unit policy. Moreover, there was no association between unit policies and prolongation of gestation in a multilevel survival analysis. Compared to a unit policy of no-use of tocolysis after PPROM, a liberal or restricted policy is not associated with improved obstetric, neonatal or two-year outcomes.

Abstract
Maternal voice is a highly relevant stimulus for newborns. Adult voice processing occurs in specific brain regions. Voice-specific brain areas in newborns and the relevance of an early vocal exposure on these networks have not been defined. This study investigates voice perception in newborns and the impact of prematurity on the cerebral processes. Functional magnetic resonance imaging (fMRI) and high-density electroencephalography (EEG) were used to explore the brain responses to maternal and stranger female voices in full-term newborns and preterm infants at term-equivalent age (TEA). fMRI results and the EEG oddball paradigm showed enhanced processing for voices in preterms at TEA than in full-term infants. Preterm infants showed additional cortical regions involved in voice processing in fMRI and a late mismatch response for maternal voice, considered as a first trace of a recognition process based on memory representation. Full-term newborns showed increased cerebral activity to the stranger voice. Results from fMRI, oddball, and standard auditory EEG paradigms highlighted important change detection responses to novelty after birth. These findings suggest that the main components of the adult voice-processing networks emerge early in development. Moreover, an early postnatal exposure to voices in premature infants might enhance their capacity to process voices.

Abstract
We summarise rates of survival and neurodevelopmental impairment in very (<32 weeks' gestation) and extremely (<28 weeks' gestation) preterm infants using data from recent meta-analyses. Methodological issues that require consideration when comparing international data are highlighted using examples of population-based or multi-centre cohorts of children born extremely preterm. The impact of baseline population, outcome definition, gestational age assessment, age at neurodevelopmental assessment, year of birth and follow-up rates are discussed. The impact of the intensity of perinatal care and of post-discharge management on survival and neurodevelopmental outcomes is also discussed. There is a future need for harmonisation of data collection and for more accurate and standardised reporting of neurodevelopmental outcomes in very preterm children.

Abstract
BACKGROUND Observational data suggest that slowly advancing enteral feeds in preterm infants may reduce necrotising enterocolitis but increase late-onset sepsis. The Speed of Increasing milk Feeds Trial (SIFT) compared two rates of feed advancement. OBJECTIVE To determine if faster (30 ml/kg/day) or slower (18 ml/kg/day) daily feed increments improve survival without moderate or severe disability and other morbidities in very preterm or very low-birthweight infants. DESIGN This was a multicentre, two-arm, parallel-group, randomised controlled trial. Randomisation was via a web-hosted minimisation algorithm. It was not possible to safely and completely blind caregivers and parents. SETTING The setting was 55 UK neonatal units, from May 2013 to June 2015. PARTICIPANTS The participants were infants born at < 32 weeks' gestation or a weight of < 1500 g, who were receiving < 30 ml/kg/day of milk at trial enrolment. INTERVENTIONS When clinicians were ready to start advancing feed volumes, the infant was randomised to receive daily feed increments of either 30 ml/kg/day or 18 ml/kg/day. In total, 1400 infants were allocated to fast feeds and 1404 infants were allocated to slow feeds. MAIN OUTCOME MEASURES The primary outcome was survival without moderate or severe neurodevelopmental disability at 24 months of age, corrected for gestational age. The secondary outcomes were mortality; moderate or severe neurodevelopmental disability at 24 months corrected for gestational age; death before discharge home; microbiologically confirmed or clinically suspected late-onset sepsis; necrotising enterocolitis (Bell's stage 2 or 3); time taken to reach full milk feeds (tolerating 150 ml/kg/day for 3 consecutive days); growth from birth to discharge; duration of parenteral feeding; time in intensive care; duration of hospital stay; diagnosis of cerebral palsy by a doctor or other health professional; and individual components of the definition of moderate or severe neurodevelopmental disability. RESULTS The results showed that survival without moderate or severe neurodevelopmental disability at 24 months occurred in 802 out of 1224 (65.5%) infants allocated to faster increments and 848 out of 1246 (68.1%) infants allocated to slower increments (adjusted risk ratio 0.96, 95% confidence interval 0.92 to 1.01). There was no significant difference between groups in the risk of the individual components of the primary outcome or in the important hospital outcomes: late-onset sepsis (adjusted risk ratio 0.96, 95% confidence interval 0.86 to 1.07) or necrotising enterocolitis (adjusted risk ratio 0.88, 95% confidence interval 0.68 to 1.16). Cost-consequence analysis showed that the faster feed increment rate was less costly but also less effective than the slower rate in terms of achieving the primary outcome, so was therefore found to not be cost-effective. Four unexpected serious adverse events were reported, two in each group. None was assessed as being causally related to the intervention. LIMITATIONS The study could not be blinded, so care may have been affected by knowledge of allocation. Although well powered for comparisons of all infants, subgroup comparisons were underpowered. CONCLUSIONS No clear advantage was identified for the important outcomes in very preterm or very low-birthweight infants when milk feeds were advanced in daily volume increments of 30 ml/kg/day or 18 ml/kg/day. In terms of future work, the interaction of different milk types with increments merits further examination, as may different increments in infants at the extremes of gestation or birthweight.

Maternal education and language development at 2 years corrected age in children born very preterm: results from a European population-based cohort study. J Epidemiol Community Health 2020; 74:346-353.

Abstract
BACKGROUND Socioeconomic factors influence language development in the general population, but the association remains poorly documented in children born very preterm (VPT). We assessed the impact of maternal education on language development in children born VPT and effect modification by perinatal risk. METHODS Data were from the Effective Perinatal Intensive Care in Europe (EPICE) population-based cohort of children born <32 weeks' gestational age (GA) in 2011/2012. Regions from six countries (Estonia, France, Germany, Italy, Sweden and UK) used a validated short form MacArthur Developmental Communicative Inventories Checklist to assess language at 2 years corrected age. Perinatal variables were collected from clinical records. We assessed expressive language delay (ELD), defined as (a) not combining words; and (b) expressive vocabulary <10th percentile of norms for age and sex. Perinatal risk (low, moderate and high) was determined using GA, small for GA and neonatal morbidities. We estimated adjusted risk ratios (aRR) of ELD by maternal education with inverse weighting to account for non-response bias. RESULTS Of 2741 children, 24.6% were not combining words and 39.7% had a low expressive vocabulary. Low maternal education (lower secondary or less compared with a bachelor's degree or more) increased risks of ELD: not combining words: aRR=1.52 (95% CI 1.36 to 1.69); low expressive vocabulary: aRR=1.25 (1.04 to 1.51). For children with low perinatal risk, the aRR were 1.88 (1.26 to 2.80) and 1.44 (1.06 to 1.95), respectively, compared with those with high perinatal risks: 1.36 (1.10 to 1.67) and 1.11 (0.97 to 1.27), respectively. CONCLUSION Low maternal education affects ELD for children born VPT, although the association appears attenuated among those with highest perinatal risk.

Abstract
INTRODUCTION Although current evidence suggests that initial dose of 200 mg/kg poractant alfa reduces mortality in the treatment of respiratory distress syndrome (RDS), these data were obtained in a highly heterogeneous group of patients and neither of them addressed mortality as primary outcome. OBJECTIVE The aim of this study was to investigate the effects of poractant alfa and beractant on mortality when administered as early rescue surfactant therapy in very preterm infants. METHODS We retrospectively evaluated preterm infants followed in our unit between May 2017 and November 2018 whose gestational age (GA) was ≤28 weeks and received surfactant within the first 2 hours of life. Morbidities and mortality rates were compared between infants who received initial doses of 200 mg/kg poractant alfa and 100 mg/kg beractant. RESULTS Data from 200 infants who met the inclusion criteria were analyzed. There were 112 patients in the poractant alfa group and 88 patients in beractant group. Mean gestational age in these groups was 26 ± 2 and 25.8 ± 1.8 weeks (P = 0.45) and mean birth weight was 812 ± 243 and 840 ± 208 g (P = 0.39), respectively. The poractant alfa and beractant groups had similar rates of overall mortality (53.5% vs 56.8%), mortality in first 7 days (30.5% vs 25.8%), and beyond day 7 (16.4% vs 13.3%) (P > 0.05). There were no differences in the incidence of preterm morbidities among the two groups. CONCLUSION We were unable to demonstrate the superiority of poractant in terms of mortality in very preterm infants with RDS. These findings need to be supported by multicenter, randomized controlled trials.

Abstract
OBJECTIVE To describe obstetrical care and in-hospital outcomes in very preterm triplet pregnancies in a European multiregional cohort. METHODS Data from a prospective population-based study of very preterm births between 22 + 0 and 31 + 6 weeks of gestation in 19 regions from 11 European countries participating in the EPICE project in 2011/2012 were used to describe triplet pregnancies and compare them with twins and singletons. RESULTS Triplets constituted 1.1% of very preterm pregnancies (97/8851) and 3.3% of very preterm live births (258/7900); these percentages varied from 0% to 2.6% and 0% to 6% respectively across the regions. In-hospital mortality after live birth was 12.4% and did not differ significantly from singletons or twins or by birth order. However, 28.9% of mothers with a triplet pregnancy experienced at least one neonatal death. Ninety percent of live-born triplets were delivered by cesarean. Vaginal delivery was associated with an Apgar score of less than 7, but not with in-hospital mortality. CONCLUSIONS The prevalence of very preterm triplets varies across European regions. Most triplets were born by cesarean and those born vaginally had lower Apgar scores. Overall, in-hospital mortality after live birth was similar to singletons and twins.

Abstract
BACKGROUND Preterm neonates can develop chronic pulmonary insufficiency of prematurity (CPIP) later in infancy. Recombinant human CC10 protein (rhCC10) is an anti-inflammatory agent that could potentially prevent CPIP. METHODS The safety and efficacy of a single intratracheal dose of rhCC10 in reducing CPIP at 12 months corrected gestational age (CGA) was evaluated in a Phase II double-blind, randomized, placebo-controlled, multisite clinical trial. Eighty-eight neonates were randomized: 22 to placebo and 22 to 1.5 mg/kg rhCC10 in the first cohort and 21 to placebo and 23 to 5 mg/kg rhCC10 in the second cohort. Neonates were followed to 12 months CGA. RESULTS With CPIP defined as signs/symptoms, medical visits, hospital readmissions, and use of medications for respiratory complications at 12 months CGA, no significant differences were observed between rhCC10 or placebo groups. Only 5% of neonates had no evidence of CPIP at 12 months CGA. CONCLUSIONS A single dose of rhCC10 was not effective in reducing CPIP at 12 CGA. Since most neonates had evidence of CPIP using these exploratory endpoints, it is essential to develop more robust outcome measures for clinical trials of respiratory medications in high-risk premature neonates.

Abstract
Background: Variability in clinical practice may influence morbidity and mortality in extremely preterm infants. We aimed to know if there are differences in survival and survival without bronchopulmonary dysplasia (BPD) in extremely preterm infants in Spanish tertiary hospitals and the potential associated factors.Methods: Fifteen hospitals from the SEN1500 network were studied. The overall rate of survival without BPD was 61.4%. Hospitals with extreme results were grouped for comparison (Group 1; N = 2480 versus Group 2; N = 2367). A bivariate analysis of the characteristics of patients and perinatal interventions was carried out and the probability of survival without BPD was studied by Cox regression.Results: Survival (79.0 versus 72.9%; p < .001) and survival without BPD (72.5 versus 49.1%; p < .001) were greater in Group 1. Higher gestational age, birth weight, and female sex were associated with better outcomes. Oxygen administration (aHR: 0.868 [95%CI: 0.782, 0.964]; p=.008) and intubation (aHR: 0.767 [95%CI: 0.701, 0.839]; p < .001) in delivery room were associated with lower survival without BPD. The occurrence of patent ductus arteriosus (PDA), sepsis and/or necrotizing enterocolitis (NEC) was independently associated with worse outcomes. After adjusting for confounders, the probabilities of survival without BPD were significantly higher among patients in Group 1: aHR: 1.557 [95% CI: 1.458, 1.662]; p < .001.Conclusions: Among the studied hospitals, we found great variability in clinical practice and in the rates of survival and survival without BPD. A more conservative approach to the use of oxygen and respiratory support seems to be related to an increase in survival without BPD. Complications such as PDA, sepsis, and/or NEC decrease survival without BPD. Other variables not included in the present study could be relevant and deserve further study.

Abstract
OBJECTIVE The documented benefits of maternal milk for very preterm infants have raised interest in hospital policies that promote breastfeeding. We investigated the hypothesis that more liberal parental policies are associated with increased breastfeeding at discharge from the neonatal unit. DESIGN Prospective area-based cohort study. SETTING Neonatal intensive care units (NICUs) in 19 regions of 11 European countries. PATIENTS All very preterm infants discharged alive in participating regions in 2011-2012 after spending >70% of their hospital stay in the same NICU (n=4407). MAIN OUTCOME MEASURES We assessed four feeding outcomes at hospital discharge: any and exclusive maternal milk feeding, independent of feeding method; any and exclusive direct breastfeeding, defined as sucking at the breast. We computed a neonatal unit Parental Presence Score (PPS) based on policies regarding parental visiting in the intensive care area (range 1-10, with higher values indicating more liberal policies), and we used multivariable multilevel modified Poisson regression analysis to assess the relation between unit PPS and outcomes. RESULTS Policies regarding visiting hours, duration of visits and possibility for parents to stay during medical rounds and spend the night in unit differed within and across countries. After adjustment for potential confounders, infants cared for in units with liberal parental policies (PPS≥7) were about twofold significantly more likely to be discharged with exclusive maternal milk feeding and exclusive direct breastfeeding. CONCLUSION Unit policies promoting parental presence and involvement in care may increase the likelihood of successful breastfeeding at discharge for very preterm infants.

Abstract
OBJECTIVE Caesarean section (CS) may reduce mortality and morbidity for very preterm breech infants, but evidence is inconclusive. We evaluated neonatal outcomes for singleton breech infants by mode of delivery in a European cohort. STUDY DESIGN Data come from the EPICE population-based cohort of very preterm births in 19 regions in 11 European countries (7770 live births). The study population was singleton spontaneous-onset breech births at 24-31 weeks gestational age (GA) without antenatal medical complications requiring caesarean delivery (N = 572). Mixed-effects regression models adjusting for maternal and pregnancy covariates and propensity score matching was used to examine the effect of (1) CS and (2) a unit policy of systematic CS for breech presentation by GA. The primary outcome was a composite of in-hospital mortality, intraventricular haemorrhage grades III & IV or cystic periventricular leukomalacia. Secondary outcomes were each component separately, five minute Apgar score below seven and mortality within six hours of delivery. RESULTS 64.4% of infants were delivered by CS with a range across regions from 41% to 100%; these infants had higher GA and were more likely to be small for gestational age, receive antenatal steroids, and have mothers who were hospitalised for more than one day before delivery compared to those delivered vaginally. CS was associated with lower risks of all outcomes in mixed-effects adjusted models (odds ratio (OR) for the composite outcome: 0.50, 95% confidence interval (CI): 0.30-0.81), but not in propensity score matched models (OR: 0.72, 95% CI: 0.41; 1.29). A systematic CS policy was associated with lower mortality and morbidity in unadjusted, but not adjusted models (OR for composite outcome: 0.76, 95% CI: 0.44; 1.28). 35% of births 24-25 weeks were delivered by CS and protective effects were consistently stronger, but not statistically significant. CONCLUSIONS Point estimates indicated protective effects of caesarean delivery for very preterm breech infants in conventional statistical models. However, analyses using propensity scores and based on unit policies did not confirm statistically significant associations. Prospective large-scale studies are needed to establish best practice and could be implemented in European regions where vaginal delivery remains an option.

Abstract
BACKGROUND A simple predictive indicator of mortality and morbidities is essential to assess neonatal illness severity and plan proper management. OBJECTIVE This study aimed to test the time-dependent performance of the Clinical Risk Index for Babies (CRIB) II in predicting mortality and major short-term morbidities among very low birth weight infants (VLBWIs). METHODS This population-based prospective study from 67 Korean Neonatal Network centers performed between 2013 and 2016 included 5,296 VLBWIs with CRIB II calculation and 6,398 infants with CRIB II calculation but without the base excess (CRIB II-BE). A regression model predicting time-dependent mortality and morbidities using the CRIB II score was designed. The discriminate ability of the CRIB II and CRIB II-BE scores in predicting mortality and morbidities was explored using receiver-operating characteristic analysis. RESULTS CRIB II performed significantly better in predicting mortality than did gestational age or birth weight alone. The time-dependent performance of CRIB II was good in the first 30 days (area under the curve [AUC], 0.8435) and at 31-90 days (AUC, 0.8458). However, it was poor after 90 days (AUC, 0.6576). Specific CRIB II cutoffs were associated with severe intraventricular hemorrhage (AUC, 0.81), bronchopulmonary dysplasia (AUC, 0.77), and mortality or major morbidities (AUC, 0.80), respectively. The model using CRIB II-BE showed similar performance in predicting mortality and morbidities to that of the CRIB II model. CONCLUSION Certain CRIB II cutoffs were significantly associated with time-dependent mortality, particularly within the first 90 days after birth as well as with short-term morbidities.

Abstract
OBJECTIVE To investigate the variation in severe neonatal morbidity among very preterm (VPT) infants across European regions and whether morbidity rates are higher in regions with low compared with high mortality rates. DESIGN Area-based cohort study of all births before 32 weeks of gestational age. SETTING 16 regions in 11 European countries in 2011/2012. PATIENTS Survivors to discharge from neonatal care (n=6422). MAIN OUTCOME MEASURES Severe neonatal morbidity was defined as intraventricular haemorrhage grades III and IV, cystic periventricular leukomalacia, surgical necrotizing enterocolitis and retinopathy of prematurity grades ≥3. A secondary outcome included severe bronchopulmonary dysplasia (BPD), data available in 14 regions. Common definitions for neonatal morbidities were established before data abstraction from medical records. Regional severe neonatal morbidity rates were correlated with regional in-hospital mortality rates for live births after adjustment on maternal and neonatal characteristics. RESULTS 10.6% of survivors had a severe neonatal morbidity without severe BPD (regional range 6.4%-23.5%) and 13.8% including severe BPD (regional range 10.0%-23.5%). Adjusted inhospital mortality was 13.7% (regional range 8.4%-18.8%). Differences between regions remained significant after consideration of maternal and neonatal characteristics (P<0.001) and severe neonatal morbidity rates were not correlated with mortality rates (P=0.50). CONCLUSION Severe neonatal morbidity rates for VPT survivors varied widely across European regions and were independent of mortality rates.

Abstract
OBJECTIVES To compare duration and changes over time in length of hospital stay for very preterm and extremely preterm infants in 10 European regions. DESIGN Two area-based cohort studies from the same regions in 2003 and 2011/2012. SETTING Ten regions from nine European countries. PATIENTS Infants born between 22 + 0 and 31 + 6 weeks of gestational age and surviving to discharge (Models of Organising Access to Intensive Care for Very Preterm Births cohort in 2003, n = 4,011 and Effective Perinatal Intensive Care in Europe cohort in 2011/2012, n = 4,336). INTERVENTIONS Observational study, no intervention. MEASUREMENTS AND MAIN RESULTS Maternal and infant characteristics were abstracted from medical records using a common protocol and length of stay until discharge was adjusted for case-mix using negative binomial regression. Mean length of stay was 63.6 days in 2003 and varied from 52.4 to 76.5 days across regions. In 2011/2012, mean length of stay was 63.1 days, with a narrower regional range (54.0-70.1). Low gestational age, small for gestational age, low 5-minute Apgar score, surfactant administration, any surgery, and severe neonatal morbidities increased length of stay. Infant characteristics explained some of the differences between regions and over time, but large variations remained after adjustment. In 2011/2012, mean adjusted length of stay ranged from less than 54 days in the Northern region of the United Kingdom and Wielkopolska, Poland to over 67 days in the Ile-de-France region of France and the Eastern region of the Netherlands. No systematic decrease in very preterm length of stay was observed over time after adjustment for patient case-mix. CONCLUSIONS A better understanding of the discharge criteria and care practices that contribute to the wide differences in very preterm length of stay across European regions could inform policies to optimize discharge decisions in terms of infant outcomes and health system costs.

Abstract
OBJECTIVES To compare survival rates and age at death among very preterm infants in 10 national and regional neonatal networks. METHODS A cohort study of very preterm infants, born between 24 and 29 weeks' gestation and weighing <1500 g, admitted to participating neonatal units between 2007 and 2013 in the International Network for Evaluating Outcomes of Neonates. Survival was compared by using standardized ratios (SRs) comparing survival in each network to the survival estimate of the whole population. RESULTS Network populations differed with respect to rates of cesarean birth, exposure to antenatal steroids and birth in nontertiary hospitals. Network SRs for survival were highest in Japan (SR: 1.10; 99% confidence interval: 1.08-1.13) and lowest in Spain (SR: 0.88; 99% confidence interval: 0.85-0.90). The overall survival differed from 78% to 93% among networks, the difference being highest at 24 weeks' gestation (range 35%-84%). Survival rates increased and differences between networks diminished with increasing gestational age (GA) (range 92%-98% at 29 weeks' gestation); yet, relative differences in survival followed a similar pattern at all GAs. The median age at death varied from 4 days to 13 days across networks. CONCLUSIONS The network ranking of survival rates for very preterm infants remained largely unchanged as GA increased; however, survival rates showed marked variations at lower GAs. The median age at death also varied among networks. These findings warrant further assessment of the representativeness of the study populations, organization of perinatal services, national guidelines, philosophy of care at extreme GAs, and resources used for decision-making.

Shim SY, Cho SJ, Kong KA, Park EA. Gestational age-specific sex difference in mortality and morbidities of preterm infants: A nationwide study. Sci Rep 2017; 7:6161. [PMID: 28733681 PMCID: PMC5522396 DOI: 10.1038/s41598-017-06490-8] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2017] [Accepted: 06/14/2017] [Indexed: 01/13/2023] Open
Abstract
This study aims to determine whether male sex has adverse effect on mortality and morbidities in very low birth weight infants (VLBWI) <30 weeks of gestation and to ascertain this sex effect, stratified by gestational age, adjusting for perinatal risk factors. This is a population-based study from Korean Neonatal Network for VLBWI born at 23+0 and 29+6 weeks of gestation between January 2013 and December 2014. The primary outcome was gestation-specific sex difference in the occurrence of mortality, combined morbidities, and individual morbidity. A total of 2228 VLBWI were enrolled (males, 51.7%). Mortality was not different between sexes. The risk of bronchopulmonary dysplasia and combined morbidities was significantly higher in males ≤25 weeks of gestation (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.35-3.20 and OR 2.00, CI 1.19-3.39, respectively). Males had a significantly higher incidence of periventricular leukomalacia at 23 and 29 weeks of gestation. The risk of severe retinopathy of prematurity was higher in females >25 weeks of gestation. Although both sexes have similar risk for mortality, male sex remains an independent risk for major morbidities, especially at ≤25 weeks of gestation. The risk of each outcome for males has a specific pattern with increasing gestational age.
