Pilarski N, Bhogal G, Hamer J, Man R, Morris RK, Hodgetts-Morton V. Interventions for women with premature cervical dilatation and exposed fetal membranes to prevent pregnancy loss and preterm birth - A systematic review and meta-analysis. Eur J Obstet Gynecol Reprod Biol 2024; 300:278-286. [PMID: 39053088 DOI: 10.1016/j.ejogrb.2024.07.022] [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: 03/28/2024] [Revised: 06/18/2024] [Accepted: 07/09/2024] [Indexed: 07/27/2024]
Abstract
INTRODUCTION The management of women with premature cervical dilatation and exposed unruptured fetal membranes remains uncertain and controversial. Treatment options may include expectant management or emergency cervical cerclage (ECC). Little is known regarding the effectiveness of individual interventions, or additional therapies. This systematic review aims to summarise all existing evidence to improve understanding of the treatment options and pregnancy outcomes for women presenting with premature cervical dilatation. METHODS Databases were searched using a prospective protocol (CRD42021286275). Studies were eligible for inclusion across five distinct comparison groups if they included women with premature cervical dilatation and reported clinical outcomes. Primary outcome was pregnancy loss (miscarriage, stillbirth, neonatal death and termination of pregnancy). Planned subgroups included singletons and twins, and low-cervical or high-cervical suture. Pairwise random effects meta-analysis calculated in RevMan5.4, single arm random effects proportional meta-analysis calculated using RevMan and R studio. Risk of bias was assessed using Cochrane Risk of Bias tool and Joanna Briggs Institute checklists. RESULTS 6781 abstracts were screened, and 177 (four randomised controlled trials) studies included in the five analysis groups. Women receiving ECC were significantly less likely to experience pregnancy loss (combined RR 0.48 95 %CI 0.39-0.59 singleton RR 0.48 95 %CI 0.34-0.67 twin only RR 0.39 95 %CI 0.26-0.58) compared to expectant management. Adjuvant amnioreduction with ECC was not found to reduce pregnancy loss (RR 1.12 (95 % CI 0.73-1.72) or any other outcomes compared to ECC without amnioreduction. Women were significantly more likely to experience pregnancy loss (RR3.85 95 %CI 3.13-4.74) after ECC compared to planned cerclage. The probability of intra-operative rupture of membranes at ECC insertion was 3.3 % (95 %CI 1.8-5.1) and the probability of an ECC attempt being abandoned was 2.6 % (95 %CI 1.1-4.6 %). DISCUSSION ECC appears to reduce the risk of pregnancy loss for both singletons and twins although the overall quality of evidence is poor. It is important that women are counselled regarding the outcomes following cerclage according to indication. Pregnancy complications are common after ECC although the rates of intra-operative complications are lower than may be anticipated. Randomised trials remain imperative for understanding the role of ECC and adjunctive treatments in preventing pregnancy loss in this condition.

Abstract
AIM The associations between the aetiology of preterm birth and later neurodevelopmental outcomes are unclear. A systematic review and meta-analysis examined the existing evidence. METHODS The PubMed and Embase databases were searched for papers published in English from inception to 16 December 2020. We included original papers on the causes of preterm birth and the risks of cerebral palsy (CP) and suboptimal cognitive development. Two reviewers independently evaluated the studies and extracted the data. RESULTS The literature search yielded 5472 papers and 13 were selected. The aetiology of preterm birth was classified under spontaneous or medically indicated delivery. A meta-analysis was performed, comprising 104 902 preterm infants from 11 papers on CP. Preterm infants born after a medically indicated delivery had a lower CP risk than infants born after spontaneous delivery, with a pooled odds ratio of 0.59 (95% confidence interval 0.40-0.86). This result was robust in the subgroup and sensitivity analyses. Cognitive development was reported in three papers, which suggested that worse outcomes were associated with medically indicated deliveries. CONCLUSION The aetiology of preterm delivery may contribute to the risk of CP and cognitive delay. Further research is needed, using individual-level meta-analyses to adjust for possible confounders, notably gestational age.

Clinical Chorioamnionitis and Neurodevelopment at 5 Years of Age in Children Born Preterm: The EPIPAGE-2 Cohort Study. J Pediatr 2024; 267:113921. [PMID: 38242316 DOI: 10.1016/j.jpeds.2024.113921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 01/04/2024] [Accepted: 01/10/2024] [Indexed: 01/21/2024]
Abstract
OBJECTIVE To assess the association between clinical chorioamnionitis and neurodevelopmental disorders at 5 years of age in children born preterm. STUDY DESIGN EPIPAGE 2 is a national, population-based cohort study of children born before 35 weeks of gestation in France in 2011. We included infants born alive between 240/7 and 346/7 weeks after preterm labor or preterm premature rupture of membranes. Clinical chorioamnionitis was defined as maternal fever before labor (>37.8°C) with ≥2 of the following criteria: maternal tachycardia, hyperleukocytosis, uterine contractions, purulent amniotic fluid, or fetal tachycardia. The primary outcome was a composite, including cerebral palsy, coordination disorders, cognitive disorders, sensory disorders, or behavioral disorders. We also analyzed each of these disorders separately as secondary outcomes. We performed a multivariable analysis using logistic regression models. We accounted for the nonindependence of twins and missing data by generalized estimating equation models and multiple imputations, respectively. RESULTS Among 2927 children alive at 5 years of age, 124 (3%) were born in a context of clinical chorioamnionitis. Overall, 8.2% and 9.6% of children exposed and unexposed, respectively, to clinical chorioamnionitis had moderate-to-severe neurodevelopmental disorders. After multiple imputations and multivariable analysis, clinical chorioamnionitis was not associated with the occurrence of moderate-to-severe neurodevelopmental disorders (aOR, 0.9; 95% CI, 0.5-1.8). CONCLUSIONS We did not find any association between clinical chorioamnionitis and neurodevelopmental disorders at 5 years of age in children born at <35 weeks of gestation after preterm labor or preterm premature rupture of membrane.

Abstract
AIM To describe the circumstances, causes and timing of death in extremely preterm infants. METHODS We included from the EPIPAGE-2 study infants born at 24-26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life-sustaining treatment (WWLST). The main cause of death was classified as respiratory disease, necrotizing enterocolitis, infection, central nervous system (CNS) injury, other or unknown. RESULTS Among 768 infants admitted to NICU, 224 died among which 89 died without WWLST and 135 with WWLST. The main causes of death were respiratory disease (38%), CNS injury (30%) and infection (12%). Among the infants who died with WWLST, CNS injury was the main cause of death (47%), whereas respiratory disease (56%) and infection (20%) were the main causes in case of death without WWLST. Half (51%) of all deaths occurred within the first 7 days of life, and 35% occurred within 8 and 28 days. CONCLUSION The death of extremely preterm infants in NICU is a complex phenomenon in which the circumstances and causes of death are intertwined.

Perinatal survival among very preterm singletons born after detection of early-onset fetal growth restriction with or without maternal hypertensive disorders: A population-based study in France. Eur J Obstet Gynecol Reprod Biol 2023; 282:43-49. [PMID: 36634405 DOI: 10.1016/j.ejogrb.2023.01.004] [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: 07/11/2022] [Revised: 12/28/2022] [Accepted: 01/03/2023] [Indexed: 01/06/2023]
Abstract
OBJECTIVE To investigate the management and survival of very preterm singletons born because of fetal growth restriction (FGR) with or without maternal hypertensive disorders in France. STUDY DESIGN From a population-based cohort of very preterm births between 22 and 31 weeks in France in 2011, the study population included all non-anomalous singleton pregnancies delivered because of detected FGR with or without maternal hypertensive disorders. Antenatal detection of FGR was defined as an estimated fetal weight <10th percentile with or without fetal Doppler abnormalities or growth arrest. All fetuses were alive at the time of detection of FGR. Indicators of active perinatal management (antenatal steroids, pre-labor cesarean and birth in level 3 maternity unit) and fetal/neonatal outcomes (terminations of pregnancy (TOP), stillbirths, neonatal deaths and survival to discharge) were compared by gestational age between FGR associated with maternal hypertensive disorders and isolated FGR. RESULTS Overall, 398 pregnancies delivered before 32 weeks for FGR associated with hypertensive disorders and 234 for isolated FGR. Active perinatal care was rare before 26 weeks in both groups and about one in five cases associated with maternal hypertensive disorders received steroids and was born by prelabor cesarean compared to none for isolated FGR. Before 25 weeks of gestation age, more pregnancies resulted in TOP when FGR was associated with hypertensive disorders compared to isolated FGR (respectively, 76.2 % vs 28.0 % at 22-23 weeks, P = 0.002 and 57.9 % vs 21.1 % at 24 weeks, P = 0.028) whereas stillbirths were more common among isolated FGR (respectively, 23.8 % vs 72.0 % at 22-23 weeks, P = 0.002 and 36.8 % vs 73.7 % at 24 weeks, P = 0.030). Survival to discharge was higher at any gestational age when the cause of birth was FGR associated with hypertensive disorders compared to isolated FGR. CONCLUSION The management and pregnancy outcomes differed when FGR was associated with maternal hypertensive disorders or isolated. The proportion of TOP was higher when FGR was associated with hypertensive disorders and the proportion of stillbirths was higher in isolated FGR.

Abstract
Background Preterm birth continues to be a leading cause of death for children under the age of 5 globally. This issue carries significant economic, psychological, and social costs for the families affected. Therefore, it is important to utilize available data to further research and understand the risk factors for preterm death. Objective The objective of this study was to determine maternal and infant complications that influence preterm deaths in a tertiary health facility in Ghana. Methods A retrospective analysis of data on preterm newborns was conducted at the neonatal intensive care unit of Korle Bu Teaching Hospital (KBTH NICU) in Ghana, covering the period January 2017 to May 2019. Pearson's Chi-square test of association was used to identify factors that were significantly associated with preterm death after admission at the NICU. The Poisson regression model was used to determine the risk factors of preterm death before discharge after admission to the NICU. Results Of the 1,203 preterm newborns admitted to the NICU in about two and half years, 355 (29.5%) died before discharge, 7.0% (n = 84) had normal birth weight (>2.5 kg), 3.3% (n = 40) had congenital anomalies and 30.5% (n = 367) were born between 34 and 37 gestational week. All 29 preterm newborns between the 18-25 gestational week died. None of the maternal conditions were significant risk factors of preterm death in the multivariable analysis. The risk of death at discharge was higher among preterm newborns with complications including hemorrhagic/hematological disorders of fetus (aRRR: 4.20, 95% CI: [1.70-10.35], p = 0.002), fetus/newborn infections (aRRR: 3.04, 95% CI: [1.02-9.04], p = 0.046), respiratory disorders (aRRR: 13.08, 95% CI: [5.50-31.10], p < 0.001), fetal growth disorders/restrictons (aRRR: 8.62, 95% CI: [3.64-20.43], p < 0.001) and other complications (aRRR: 14.57, 95% CI: [5.93-35.77], p < 0.001). Conclusion This study demonstrate that maternal factors are not significant risk factors of preterm deaths. Gestational age, birth weight, presence of complications and congenital anomalies at birth are significantly associated with preterm deaths. Interventions should focus more on child health conditions at birth to reduce the death of preterm newborns.

The introduction of a universal transvaginal cervical length screening program is associated with a reduced preterm birth rate. Am J Obstet Gynecol 2023; 228:219.e1-219.e14. [PMID: 35932876 DOI: 10.1016/j.ajog.2022.07.046] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 07/25/2022] [Accepted: 07/27/2022] [Indexed: 01/28/2023]
Abstract
BACKGROUND Midtrimester sonographic short cervix is a good predictor of preterm birth in singleton pregnancies. OBJECTIVE This study aimed to assess the impact of implementing a universal transvaginal cervical length screening program on preterm birth rate. STUDY DESIGN This study consisted of 2 parts: a before-and-after multicenter study and a study on the ECHOCOL ("echo"="ultrasound" and "col"="cervix" in French) prospective cohort. We compared the rate of preterm birth before and after the introduction of universal cervical length screening at the time of midtrimester anatomy ultrasound. The multicenter before-and-after regional study included all women with a singleton pregnancy who gave birth after 24 weeks' gestation in the South East of France from January 1, 2012 to April 30, 2018. In parallel, the ECHOCOL cohort study was prospectively conducted from May 2015 to July 2018, including 17 maternity hospitals in the South East region of France. In case of asymptomatic short cervix <25 mm, treatments offered included 200 mg of vaginal progesterone, or cerclage, or a pessary until 34 weeks' gestation. RESULTS We observed a significant decrease rate of preterm birth between periods A and B after multivariate analysis. (respectively, 5.8% vs 5.6%; adjusted odds ratio, 0.92; 95% confidence interval, 0.89-0.95; P<.0001). In parallel, the percentage of cervical length screening significantly increased from 28.9% in period A to 52.9% in period B (odds ratio, 2.76; 95% confidence interval, 2.71-2.80; P<.0001). Among the 3468 patients of the ECHOCOL prospective cohort, 38 (1.1%) asymptomatic short cervices were detected, and 192 patients gave birth prematurely (11 with an asymptomatic short cervix and 181 without). In the ECHOCOL cohort, a marked but statistically insignificant tendency toward a reduced rate of preterm birth before 37 weeks of gestation was observed (from 5.8% to 5.5%; adjusted odds ratio, 0.72; 95% confidence interval, 0.51-1.03; P=.068). CONCLUSION This study showed a significantly lower rate of preterm birth after the implementation of a universal cervical length screening and treating policy during the second trimester of pregnancy. The clinical trial was registered under NCT02598323.

Abstract
OBJECTIVE We examined the effects of maternal hypertensive disorders of pregnancy (HDP) on the mortality and neurodevelopmental outcomes in preterm very low birth weight (VLBW) infants (BW ≤1,500 g) based on their intrauterine growth status and gestational age (GA). STUDY DESIGN We included singleton VLBW infants born at <32 weeks' gestation registered in the Neonatal Research Network Japan database. The composite outcomes including death, cerebral palsy (CP), and developmental delay (DD) at 3 years of age were retrospectively compared among three groups: appropriate for GA (AGA) infants of mothers with and without HDP (H-AGA and N-AGA) and small for GA (SGA) infants of mothers with HDP (H-SGA). The adjusted odds ratios (AOR) and 95% confidence intervals (CI) stratified by the groups of every two gestational weeks were calculated after adjusting for the center, year of birth, sex, maternal age, maternal diabetes, antenatal steroid use, clinical chorioamnionitis, premature rupture of membranes, non-life-threatening congenital anomalies, and GA. RESULTS Of 19,323 eligible infants, outcomes were evaluated in 10,192 infants: 683 were H-AGA, 1,719 were H-SGA, and 7,790 were N-AGA. Between H-AGA and N-AGA, no significant difference was observed in the risk for death, CP, or DD in any GA groups. H-AGA had a lower risk for death, CP, or DD than H-SGA in the 24 to 25 weeks group (AOR: 0.434, 95% CI: 0.202-0.930). The odds for death, CP, or DD of H-SGA against N-AGA were found to be higher in the 24 to 25 weeks (AOR: 2.558, 95% CI: 1.558-3.272) and 26 to 27 weeks (AOR: 1.898, 95% CI: 1.427-2.526) groups, but lower in the 30 to 31 weeks group (AOR: 0.518, 95% CI: 0.335-0.800). CONCLUSION There was a lack of follow-up data; however, the outcomes of liveborn preterm VLBW infants of mothers with HDP depended on their intrauterine growth status and GA at birth. KEY POINTS · The effects of HDP on preterm low birth weight infants need to be further examined.. · The outcomes were not different between AGA infants with and without maternal HDP.. · The outcomes of SGA infants with maternal HDP were dependent on their GA..

Metabonomics profile analysis in inflammation-induced preterm birth and the potential role of metabolites in regulating premature cervical ripening. Reprod Biol Endocrinol 2022; 20:135.

Abstract
BACKGROUND Preterm birth (PTB) is the primary cause of infant morbidity and mortality. Moreover, previous studies have established that PTB is related to premature cervical ripening. However, the underlying mechanism remains to be elucidated. This study sought to identify differentially expressed metabolites and investigate their potential biological functions in PTB. METHODS Pregnant C57BL/6 J mice were treated with either LPS or normal saline and cervical alterations before labor were detected by staining. Metabolic profiles in the plasma of PTB and control mice were examined through non-targeted metabonomics analyses, quantitative polymerase chain reaction and immunofluorescence staining were performed on human cervical smooth cells. RESULTS The study demonstrated that the mRNA and protein levels of α-SMA, SM-22, and calponin in cervical smooth muscle cells of PTB mice were lower while OR was higher at both mRNA and protein levels compared to the CTL group. A total of 181 differentially expressed metabolites were analyzed, among them, 96 were upregulated, while 85 were downregulated in the PTB group. Differentially expressed metabolites may play a role in STAT3, RhoA, mTOR, TGF-β, and NK-κB signaling pathways. Furthermore, when treated with taurine, the levels of α-SMA and SM-22 in human cervical smooth muscle cells were elevated, whereas that of connexin-43 was decreased. CONCLUSION Our study highlighted the changes of metabolites in the peripheral blood changed prior to PTB and revealed that these differentially expressed metabolites might participate in the development of premature cervical ripening. Taurine was identified as an important metabolite may modulate human cervical smooth muscle cells. Our study provided new insights into the mechanism underlying premature cervical ripening in PTB.

Abstract
Preterm birth is associated with an elevated risk of developmental and adult psychiatric disorders, including psychosis. In this review, we evaluate the implications of neurodevelopmental, cognitive, motor, and social sequelae of preterm birth for developing psychosis, with an emphasis on outcomes observed in adulthood. Abnormal brain development precipitated by early exposure to the extra-uterine environment, and exacerbated by neuroinflammation, neonatal brain injury, and genetic vulnerability, can result in alterations of brain structure and function persisting into adulthood. These alterations, including abnormal regional brain volumes and white matter macro- and micro-structure, can critically impair functional (e.g. frontoparietal and thalamocortical) network connectivity in a manner characteristic of psychotic illness. The resulting executive, social, and motor dysfunctions may constitute the basis for behavioural vulnerability ultimately giving rise to psychotic symptomatology. There are many pathways to psychosis, but elucidating more precisely the mechanisms whereby preterm birth increases risk may shed light on that route consequent upon early neurodevelopmental insult.

Abstract
OBJECTIVE To assess the association between early empirical antibiotics and neonatal adverse outcomes in very preterm infants without risk factors for early-onset sepsis (EOS). STUDY DESIGN This is a secondary analysis of the EPIPAGE-2 study, a prospective national population-based cohort that included all liveborn infants at 22-31 completed weeks of gestation in France in 2011. Infants at high risk of EOS (ie, born after preterm labor or preterm premature rupture of membranes or from a mother who had clinical chorioamnionitis or had received antibiotics during the last 72 hours) were excluded. Early antibiotic exposure was defined as antibiotic therapy started at day 0 or day 1 of life, irrespective of the duration and type of antibiotics. We compared treated and untreated patients using inverse probability of treatment weighting based on estimated propensity scores. RESULTS Among 648 very preterm infants at low risk of EOS, 173 (26.2%) had received early antibiotic treatment. Early antibiotic exposure was not associated with death or late-onset sepsis or necrotizing enterocolitis (OR, 1.04; 95% CI, 0.72-1.50); however, it was associated with higher odds of severe cerebral lesions (OR, 2.71; 95% CI, 1.25-5.86) and moderate-severe bronchopulmonary dysplasia (BPD) (OR, 2.30; 95% CI, 1.21-4.38). CONCLUSIONS Early empirical antibiotic therapy administrated in very preterm infants at low risk of EOS was associated with a higher risk of severe cerebral lesions and moderate-severe BPD.

Abstract
Premature birth is a worldwide public health priority. One in ten children is born before 37 weeks of gestational age and, in developed countries, survival rates without major neonatal morbidity are increasing. Although severe sequelae associated with these births have decreased, their neurobehavioral difficulties, often associated in multiple fields, remain stable but still widespread. These neurobehavioral difficulties hamper the normal development of academic achievements and societal integration and intensify the children's needs for rehabilitation during their preschool and academic years. Severe sequelae increase when gestational age decreases. This is even truer if the socio-cultural background is impeded by low income, education and language skills as compared with defined averages. However, moderate and/or minor neurocognitive and/or behavioral difficulties are almost identical for a moderate or a late preterm birth. Obtaining a better clinical description of neurobehavioral characteristics of those pretermly born, once they reach preschool age, is essential to detect behavioral issues as well as early specific cognitive difficulties (working memory, planning, inhibition, language expression and reception, attention and fine motor skills, etc.). Such information would provide a better understanding of the executive functions' role in brain connectivity, neurodevelopment and neuroanatomical correlation with premature encephalopathy.

Front Pediatr 2022; 10:977422. [PMID: 36061390 PMCID: PMC9433924 DOI: 10.3389/fped.2022.977422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 08/01/2022] [Indexed: 11/29/2022] Open
Abstract
OBJECTIVES The evidence that risks of morbidity and mortality are higher when very premature newborns are born during the on-call period is inconsistent. This study aimed to assess the impact of this situation among other determinants of outcomes, particularly newborn characteristics and care organization. METHODS Observational study including all infants born < 30 weeks' gestation in a French tertiary perinatal center between 2007 and 2020. On-call period corresponded to weekdays between 6:30 p.m. and 8:30 a.m., weekends, and public holidays. The primary endpoint was survival without severe morbidity, including grade 3-4 intraventricular hemorrhage (IVH), cystic periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia (BPD), and severe retinopathy of prematurity. The relationship between admission and outcome was assessed by an adjusted odds ratio (aOR) on the propensity of being born during on-call period and expressed vs. weekday. Secondary analyses were carried out in extremely preterm newborns (<27 weeks' gestation), in cases of early death (within 7 days), and before (2007-2013, 51.5% of the cohort) vs. after (2014-2020, 48.5% of the cohort) the implementation of a pediatrician-nurse team dedicated to newborn care in the delivery room. RESULTS A total of 1,064 infants [27.9 (26.3; 28.9) weeks, 947 (760; 1,147) g] were included: 668 during the on-call period (63%) and 396 (37%) on weekdays. For infants born on weekdays, survival without severe morbidity was 54.5% and mortality 19.2%. During on-call, these rates were 57.3% [aOR 1.08 (0.84-1.40)] and 18.4% [aOR 0.93 (0.67-1.29)]. Comparable rates of survival without severe morbidity [aOR 1.42 (0.87-2.34)] or mortality [aOR 0.76 (0.47-1.22)] were observed in extremely preterm infants. The early death rate was 6.4% on weekdays vs. 8.2% during on-call [aOR 1.44 (0.84-2.48)]. Implementation of the dedicated team was associated with decreased rates of mortality [aOR 0.57 (0.38, 0.85)] and grade 3-4 IVH [aOR 0.48 (0.30, 0.75)], and an increased rate of severe BPD [aOR 2.16 (1.37, 3.41)], for infants born during on-call. CONCLUSION In this cohort, most births of very premature neonates occurred during the on-call period. A team dedicated to newborn care in the delivery room may have a favorable effect on the outcome of infants born in this situation.

[PMID: 33395567 DOI: 10.1016/j.jpeds.2020.12.069] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 12/23/2020] [Accepted: 12/29/2020] [Indexed: 12/25/2022]
Abstract
OBJECTIVE To evaluate the association of early continuous infusions of opioids and/or midazolam with survival and sensorimotor outcomes at age 2 years in very premature infants who were ventilated. STUDY DESIGN This national observational study included premature infants born before 32 weeks of gestation intubated within 1 hour after birth and still intubated at 24 hours from the French EPIPAGE 2 cohort. Infants only treated with bolus were excluded. Treated infants received continuous opioid and/or midazolam infusion started before 7 days of life and before the first extubation. Naive infants did not receive these treatments before the first extubation, or received them after the first week of life, or never received them. This study compared treated (n = 450) vs naive (n = 472) infants by using inverse probability of treatment weighting after multiple imputation in chained equations. The primary outcomes were survival and survival without moderate or severe neuromotor or sensory impairment at age 2 years. RESULTS Survival at age 2 years was significantly higher in the treated group (92.5% vs 87.9%, risk difference, 4.7%; 95% CI, 0.3-9.1; P = .037), but treated and naive infants did not significantly differ for survival without moderate or severe neuromotor or sensory impairment (86.6% vs 81.3%; risk difference, 5.3%; 95% CI -0.3 to 11.0; P = .063). These results were confirmed by sensitivity analyses using 5 alternative models. CONCLUSIONS Continuous opioid and/or midazolam infusions in very premature infants during initial mechanical ventilation that continued past 24 hours of life were associated with improved survival without any difference in moderate or severe sensorimotor impairments at age 2 years.

[Influence of premature rupture of membranes on the early prognosis of extremely premature infants]. ZHONGGUO DANG DAI ER KE ZA ZHI = CHINESE JOURNAL OF CONTEMPORARY PEDIATRICS 2021.

Abstract
OBJECTIVE To study the influence of premature rupture of membranes (PROM) on the early prognosis of extremely premature infants, and to provide a basis for the management of extremely premature infants and prenatal consultation. METHODS A total of 179 extremely premature singleton infants who were born from 2017 to 2019 were enrolled. According to the presence or absence of PROM, they were divided into two groups: PROM group (n=69) and non-PROM group (n=110). A statistical analysis was performed for maternal data and early prognostic indicators. RESULTS Compared with the non-PROM group, the PROM group had significantly higher incidence rates of earlyonset sepsis and necrotizing enterocolitis (NEC) (P < 0.05) and significantly lower rate of use of pulmonary surfactant and incidence rate of hemodynamically significant patent ductus arteriosus (P < 0.05). The multivariate logistic regression analysis showed that chorioamnionitis was an independent risk factor for early-onset sepsis and NEC (OR=11.062 and 9.437 respectively, P < 0.05), and PROM was an independent protective factor against the use of pulmonary surfactant (OR=0.363, P < 0.05). CONCLUSIONS PROM increases the incidence rates of early-onset sepsis and NEC in extremely premature infants and does not increase the incidence rates of other adverse outcomes. For pregnant women with PROM at the risk of extremely preterm delivery, prevention of miscarriage and chorioamnionitis is recommended to prolong gestational weeks, reduce the incidence rate of infection, and thus improve the outcome of extremely premature infants.

Abstract
BACKGROUND The pathogenesis of late-onset sepsis (LOS) in preterm infants is poorly understood and knowledge about risk factors, especially prenatal risk factors, is limited. This study aimed to assess the association between the cause of preterm birth and LOS in very preterm infants. METHODS 2052 very preterm singletons from a national population-based cohort study alive at 72 h of life were included. Survival without LOS was compared by cause of preterm birth using survival analysis and Cox regression models. RESULTS 437 (20.1%) had at least one episode of LOS. The frequency of LOS varied by cause of preterm birth: 17.1% for infants born after preterm labor, 17.9% after preterm premature rupture of membranes, 20.3% after a placental abruption, 20.3% after isolated hypertensive disorders, 27.5% after hypertensive disorders with fetal growth restriction (FGR), and 29.4% after isolated FGR. In multivariate analysis, when compared to infants born after preterm labor, the risk remained higher for infants born after hypertensive disorders (hazard ratio HR = 1.7, 95% CI = 1.2-2.5), hypertensive disorders with FGR (HR = 2.6, 95% CI = 1.9-3.6) and isolated FGR (HR = 2.9, 95% CI = 1.9-4.4). CONCLUSION Very preterm infants born after hypertensive disorders or born after FGR had an increased risk of LOS compared to those born after preterm labor. IMPACT Late-onset sepsis risk differs according to the cause of preterm birth. Compared with those born after preterm labor, infants born very preterm because of hypertensive disorders of pregnancy and/or fetal growth restriction display an increased risk for late-onset sepsis. Antenatal factors, in particular the full spectrum of causes leading to preterm birth, should be taken into consideration to better prevent and manage neonatal infectious morbidity and inform the parents.

Abstract
INTRODUCTION Retinopathy of prematurity (ROP) is a blinding disease that requires screening by retinal examination. Screening practices are rarely evaluated. We aimed to determine the prevalence of ROP screening in very preterm infants and individual- and center-related factors associated with ROP screening. METHODS Data were extracted from the EPIPAGE-2 cohort, a French prospective population-based study of premature births in 2011. Children born before 32 weeks' gestation (WG) without severe malformation and alive at the recommended time for ROP screening were included. Outcome measures were achievement of ROP screening and compliance with recommended screening timeline. Individual- and center-related factors associated with both measures were studied using mixed models. RESULTS Among 3,077 eligible infants, 2,169 (70.5%) had a ROP screening, ranging from 96% at 24 WG to 50% at 31 WG. Large variability among units was observed. Individual characteristics associated with screening were low gestational age, low birth weight, severe bronchopulmonary dysplasia or neurological lesions, and transfer between neonatal units during the screening period. Odds of screening were higher in neonatal units using wide-angle imaging (odds ratio 2.65 [95% confidence interval 1.17-6.01]) but decreased in units without a local protocol for ROP screening (0.03 [0.01-0.09]). Among screened children, 1,641/2,169 (75.7%) were screened according to recommended timeline. Delayed screening was associated with low gestational age, severe bronchopulmonary dysplasia or necrotizing enterocolitis, and absence of local protocol for ROP screening. DISCUSSION/CONCLUSIONS In this large cohort study of infants born very preterm, almost one-third were not screened for ROP. Children most at risk for ROP were the best screened but often with delay. The higher compliance of neonatal units using wide-angle imaging systems supports its use.

Abstract
OBJECTIVE To investigate the association between absent or reversed end-diastolic flow (ARED) on umbilical artery Doppler ultrasound and poor neurological outcome at 2 years of age after very preterm birth associated with suspected fetal growth restriction (FGR) or maternal hypertensive disorders. METHODS The study population comprised all very preterm (22-31 completed weeks) singleton pregnancies delivered because of suspected FGR and/or maternal hypertensive disorders that had umbilical artery Doppler and 2-year follow-up available included in EPIPAGE-2, a prospective, nationwide, population-based cohort of preterm births in France in 2011. Univariate and two-level multivariable logistic regression analyses were used to assess the association of ARED in the umbilical artery, as compared with normal or reduced end-diastolic flow, with severe or moderate neuromotor and/or sensory disability and with an Ages and Stages Questionnaire (ASQ) score below a threshold. This was defined as a score more than 2 SD below the mean in any of the five domains, at age 2, adjusting for gestational age at delivery. ASQ is used to identify children at risk of developmental delay requiring reinforced follow-up and further evaluation. Descriptive statistics and bivariate tests were weighted according to the duration of the inclusion periods. RESULTS The analysis included 484 children followed up at 2 years of age, for whom prenatal umbilical artery Doppler ultrasound was available. Among them, 8/484 (1.6%) had severe or moderate neuromotor and/or sensory disability, and 156/342 (45.4%) had an ASQ score below the threshold. Compared with normal or reduced end-diastolic flow in the umbilical artery (n = 305), ARED (n = 179) was associated with severe or moderate neuromotor and/or sensory disability (adjusted odds ratio (OR), 11.3; 95% CI, 1.4-93.2) but not with an ASQ score below the threshold (adjusted OR, 1.2; 95% CI, 0.8-1.9). CONCLUSION Among children delivered before 32 weeks of gestation due to suspected FGR and/or maternal hypertensive disorder who survived until 2 years of age, prenatal ARED in the umbilical artery was associated with a higher incidence of severe or moderate neuromotor and/or sensory disability.

Abstract
OBJECTIVE To evaluate the impact of pre-eclampsia on cesarean delivery by using the Robson classification. METHODS A retrospective cross-sectional study including all women who delivered in a referral maternity hospital in southeast Brazil from January 2017 to February 2018. Women were classified into 1 of 10 Robson groups and then further subdivided into pre-eclampsia (PE) and non-PE (NPE) groups. Frequency of cesarean was determined for each group and compared by using χ2 and prevalence ratio. RESULTS Overall, 3102 women were included, of whom 1578 (50.9%) delivered by cesarean. Classification in Robson group 5 was the most frequent among all women (n=727, 23.4%). In the PE group (n=258, 8.3%), group 10 was the most frequent classification (n=120, 46.5%); in NPE, Robson group 5 was the most frequency (n=682, 24.0%). Pre-eclampsia was associated with a higher occurrence of cesarean (77.5% vs 48.4%; prevalence ratio, 2.29; 95% confidence interval, 1.82-2.82), owing to higher rates in Robson groups 1, 5, and 10. CONCLUSION Pre-eclampsia was associated with a higher occurrence of cesarean delivery in some Robson groups. Robson classification may be used to evaluate the impact of specific conditions at a facility level to help plan future interventions to optimize the use of cesarean.

Abstract
INTRODUCTION Recent studies have shown that the cause of very preterm births may be related to neonatal morbidity and mortality. Even though these risks are lower among late preterm births, this group accounts for the vast majority of all preterm births. The objective of this study was to evaluate the relation of neonatal morbidity and mortality to the cause of late preterm birth. MATERIALS AND METHODS This retrospective observational cohort study included all women who gave birth to liveborn singletons from 34 to 36 weeks+6 days of gestation in a French level III maternity hospital in the 5-year period 2013-2017. The causes of preterm delivery were divided into 6 mutually exclusive groups. The main outcome was a composite neonatal morbidity criterion, defined by at least one among the following criteria: neonatal respiratory distress, neurological complications, neonatal sepsis, severe necrotizing enterocolitis, and neonatal hypoglycemia. We analyzed the association between cause of preterm delivery and neonatal morbidity after adjustment for gestational age and antenatal corticosteroid therapy. The reference group was preterm labor, defined by spontaneous preterm labor with intact membranes. RESULTS During the study period, there were a total of 27 110 births, including 1114 singleton births at 34 to 36 weeks of gestation + 6 days (4.1%). Among the 968 late preterm births included, the risk of neonatal morbidity in the group with preterm premature rupture of membranes (PPROM) was similar to that in the preterm labor (reference) group: adjusted odds ratio (aOR) 1.2 (95% CI, 0.8-1.8). All the other causes of late preterm birth were associated with a higher risk of neonatal morbidity than the reference group: aOR 2.0 [95% CI, 1.1-3.5] for hypertensive disorders without suspected fetal growth restriction (FGR) (9.1% of cases), aOR 2.4 [95% CI, 1.4-4.2] for hypertensive disorders with suspected FGR (8.9%), aOR 4.2 [95% CI, 2.2-8.0] for suspected FGR without hypertensive disorders (5.8%), and aOR 4.4 [95% CI, 2.2-8.8] for vaginal bleeding related to abnormal placental insertion (4.7%). CONCLUSION Among infants born from 34 to 36 weeks + 6 days of gestation, PPROM and preterm labor had similar risks of neonatal morbidity, while the other causes were associated with a risk of neonatal morbidity at least twice that with preterm labor.

Planned delivery route and outcomes of cephalic singletons born spontaneously at 24-31 weeks' gestation: The EPIPAGE-2 cohort study. Acta Obstet Gynecol Scand 2020; 99:1682-1690. [PMID: 32557537 DOI: 10.1111/aogs.13939] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 05/26/2020] [Accepted: 06/05/2020] [Indexed: 11/26/2022]
Abstract
INTRODUCTION The objective of this study was to investigate the association between planned mode of delivery and neonatal outcomes with spontaneous very preterm birth among singletons in cephalic presentation. MATERIAL AND METHODS Etude Epidémiologique sur les Petits Ages Gestationnels 2 is a French national, prospective, population-based cohort study of preterm infants. For this study, we included women with a singleton cephalic pregnancy and spontaneous preterm labor or preterm premature rupture of membranes at 24-31 weeks' gestation. The main exposure was the planned mode of delivery (ie planned vaginal delivery or planned cesarean delivery at the initiation of labor). The primary outcome was survival at discharge and secondary outcome survival at discharge without severe morbidity. Propensity scores were used to minimize indication bias in estimating the association. RESULTS The study population consisted of 1008 women: 206 (20.4%) had planned cesarean delivery and 802 (79.6%) planned vaginal delivery. In all, 723 (90.2%) finally had a vaginal delivery. Overall, 187 (92.0%) and 681 (87.0%) neonates in the planned cesarean delivery and planned vaginal delivery groups were discharged alive, and 156 (77.6%) and 590 (76.3%) were discharged alive without severe morbidity. After matching on propensity score, planned cesarean delivery was not associated with survival (adjusted odds ratio [aOR] 1.05, 95% confidence interval [CI] 0.48-2.28) or survival without severe morbidity (aOR 0.64, 95% CI 0.36-1.16). CONCLUSIONS Planned cesarean delivery for cephalic presentation at 24-31 weeks' gestation after preterm labor or preterm premature rupture of membranes does not improve neonatal outcomes.

Abstract
PURPOSE Preterm birth (PTB) can be categorised according to aetiology into: spontaneous preterm labour (SPL), preterm prelabour rupture of membranes (PPROM), and iatrogenic (iatro) PTB. Outcomes could differ between these groups, which could be of interest in counselling. We aimed to explore differences between aetiologic groups of PTB in maternal demographics, obstetrical characteristics and management, and neonatal outcomes. METHODS This is a cohort study (2012-2018) in Ghent University Hospital, Belgium, of deliveries from 24 + 0 to 33 + 6 weeks. We compared perinatal demographics, management, and outcomes between the aetiologic types of PTB. Point and interval estimates for differences between aetiologic types were estimated using a Generalised Estimating Equations approach to handle clustering due to multiple gestations. RESULTS 813 mothers and 987 neonates were included. Prevalences of different aetiologic types of PTB were similar. Maternal BMI was higher in the iatrogenic group (iatro-SPL: + 1.92 kg/m2, 95% CI 1.02, 2.83; iatro-PPROM: + 2.06 kg/m2, 95% CI 1.15, 2.96). There was an inversed sex ratio (0.82, 95% CI 0.65, 1.03), more growth restriction (iatro-SPL: + 22.60%, 95% CI 17.08, 28.13; iatro-PPROM: + 24.64%, 95% CI 19.44, 29.83), and a higher caesarean section rate in the iatrogenic group (iatro-SPL: + 57.23%, 95% CI 50.32, 64.13, iatro-PPROM: + 56.79%, 95% CI 50.20, 63.38) and more patients received at least one complete course of antenatal corticosteroids (iatro-SPL: + 17.60%, 95% CI 10.60, 24.60, iatro-PPROM: + 10.73%, 95% CI 4.52, 16.94). In all types of PTB, adverse neonatal outcomes had a low prevalence, except for respiratory distress syndrome. A composite of adverse neonatal outcome was more prevalent in the SPL- compared to the PPROM group, and there was less intraventricular haemorrhage in the iatrogenic group. CONCLUSION Additional to gestational age at birth, the aetiology of PTB is associated with neonatal outcome. More data are needed to enable individualised management and counselling in case of threatened PTB. TRIAL REGISTRATION NUMBER NCT03405116.

Abstract
OBJECTIVE To assess whether chorioamnionitis is associated with cerebral palsy (CP) or death at 2 years' corrected age in infants born before 32 weeks of gestation after spontaneous birth. STUDY DESIGN EPIPAGE-2 is a national, prospective, population-based cohort study of children born preterm in France in 2011; recruitment periods varied by gestational age. This analysis includes infants born alive after preterm labor or preterm premature rupture of membranes from 240/7 to 316/7 weeks of gestation. We compared the outcomes of CP, death at 2 years' corrected age, and "CP or death at age 2" according to the presence of either clinical chorioamnionitis or histologic chorioamnionitis. All percentages were weighted by the duration of the recruitment period. RESULTS Among 2252 infants born alive spontaneously before 32 weeks of gestation, 116 (5.2%) were exposed to clinical chorioamnionitis. Among 1470 with placental examination data available, 639 (43.5%) had histologic chorioamnionitis. In total, 346 infants died before 2 years and 1586 (83.2% of the survivors) were evaluated for CP at age 2 years. CP rates were 11.1% with and 5.0% without clinical chorioamnionitis (P = .03) and 6.1% with and 5.3% without histologic chorioamnionitis (P = .49). After adjustment for confounding factors, CP risk rose with clinical chorioamnionitis (aOR 2.13, 95% CI 1.12-4.05) but not histologic chorioamnionitis (aOR 1.21, 95% 0.75-1.93). Neither form was associated with the composite outcome "CP or death at age 2." CONCLUSIONS Among infants very preterm born spontaneously, the risk of CP at a corrected age of 2 years was associated with exposure to clinical chorioamnionitis but not histologic chorioamnionitis.

Abstract
OBJECTIVES To describe patterns of care for very preterm (VP) babies across neonatal intensive care units (NICUs) and associations with outcomes. DESIGN Prospective cohort study, EPIPAGE-2. SETTING France, 2011. PARTICIPANTS 53 (NICUs); 2135 VP neonates born at 27 to 31 weeks. OUTCOME MEASURES Clusters of units, defined by the association of practices in five neonatal care domains - respiratory, cardiovascular, nutrition, pain management and neurodevelopmental care. Mortality at 2 years corrected age (CA) or severe/moderate neuro-motor or sensory disabilities and proportion of children with scores below threshold on the neurodevelopmental Ages and Stages Questionnaire (ASQ). METHODS Hierarchical cluster analysis to identify clusters of units. Comparison of outcomes between clusters, after adjustment for potential cofounders. RESULTS Three clusters were identified: Cluster 1 with higher proportions of neonates free of mechanical ventilation at 24 hours of life, receiving early enteral feeding, and neurodevelopmental care practices (26 units; n=1118 babies); Cluster 2 with higher levels of patent ductus arteriosus and pain screening (11 units; n=398 babies); Cluster 3 with higher use of respiratory, cardiovascular and pain treatments (16 units; n=619 babies). No difference was observed between clusters for the baseline maternal and babies' characteristics. No differences in outcomes were observed between Clusters 1 and 3. Compared with Cluster 1, mortality at 2 years CA or severe/moderate neuro-motor or sensory disabilities was lower in Cluster 2 (adjusted OR 0.46, 95% CI 0.25 to 0.84) but with higher proportion of children with an ASQ below threshold (adjusted OR 1.49, 95% CI 1.07 to 2.08). CONCLUSION In French NICUs, care practices for VP babies were non-randomly associated. Differences between clusters were poorly explained by unit or population differences, but were associated with mortality and development at 2 years. Better understanding these variations may help to improve outcomes for VPT babies, as it is likely that some of these discrepancies are unwarranted.

Abstract
OBJECTIVE To evaluate whether gestational age was associated with the severe maternal morbidity (SMM) of preterm cesarean delivery between 22 and 34 weeks of gestation (weeks). MATERIAL AND METHODS We performed an observational retrospective cohort study in two tertiary university hospitals in 2018. We included all mothers of preterm infants born by caesarean delivery between 22 and 34 weeks, excluding mothers with multiple births greater than two, with pregnancy terminations or stillbirths, and who died unrelated to obstetrical causes. The principal endpoint, SMM, was a composite outcome (classical uterine incision, postpartum hemorrhage defined by blood loss ≥ 500 mL, blood transfusion, any injury to adjacent organs, unplanned procedure/need for reintervention, Intensive Care Unit (ICU) stay longer than 24 h, postpartum fever, and/or death). RESULTS Among the 252 women, SMM occurred in 89 (35.3 %) cases. After multivariate analysis, gestational age was independently associated with SMM (adjusted Odds Ratio [aOR] 0.87; 95 % Confidence Interval [CI] 0.78-0.97). The other variables statistically associated with SMM were type of pregnancy with a negative association with twin pregnancy (aOR, 0.44; 95 % CI, 0.20-0.93) and a positive association with general anesthesia (aOR, 2.52; 95 % CI, 1.25-5.13). A sensitivity analysis was performed and found an association, at the limit of significance, between gestational age < 28 weeks and SMM (aOR, 1.80; 95 % CI, 0.99-3.27, p = 0.05). CONCLUSION Lower gestational age was associated with the risk of SMM for preterm caesarean delivery between 22 and 34 weeks. Obstetricians should integrate this knowledge into their shared decision-making processes with parents.

Abstract
The aim of the study was to investigate whether serum hypoxia-inducible factor-1alpha (HIF-1α), hepcidin and interleukin-6 (IL-6) concentrations differed between threatened preterm labour (TPL) and uncomplicated pregnancies. This study was conducted on 54 women with TDL pregnancies and 26 healthy pregnant women. The TPL group was further divided into two subgroups according to the gestational age at delivery. Patients who gave birth within 48-72 h after the hospitalisation were referred to as preterm delivery (PD) and who gave birth at ≥37 weeks were referred to as term delivery (TD). Maternal levels of serum HIF-1α, hepcidin and IL-6 were measured with the use of enzyme-linked immunosorbent assay kits. The mean maternal serum HIF-1α, hepcidin and IL-6 levels of PD were significantly higher than TD (p < .001*) and control group (p < .001*). The mean maternal serum HIF-1α and hepcidin levels of TD were no significantly higher than the control group (p=.058, p = .064). The mean maternal serum IL-6 level of TD was significantly higher than the control group (p < .001*). A negative correlation was found between serum concentration of HIF1α, hepcidin, IL-6 with the gestational week of delivery (r = -0.421, p < .01* for HIF-1α; r = -0.578, p < .01* for hepcidin and r = -0.435, p < .01* for IL-6). High levels of HIF-1α, hepcidin and IL-6 may have potential to be used as biomarkers for the differentiation of PD and TD.Impact statementWhat is already known on this subject? It is known that hypoxia-inducible factor-1alpha (HIF-1α) is a hypoxia marker and hepcidin and interleukin-6 (IL-6) increase in inflammation. Our study is the comparison of maternal serum HIF-1α, hepcidin and IL-6 levels between the TPL group (TD and PD) and healthy control group.What the results of this study add? The present study demonstrates that serum HIF-1α, hepcidin and IL-6 levels were significantly higher in TPD group than uncomplicated group. The mean maternal serum HIF-1α and hepcidin levels of TD were no significantly higher than the control group.What the implications are of these findings for clinical practice and/or further research? High levels of HIF-1α, hepcidin and IL-6 may be biomarkers in the determination of true preterm labour within the TPL group.

Abstract
OBJECTIVE To estimate the prevalence of severe maternal morbidity among very preterm births and determine its association with very preterm infant mortality and morbidity. STUDY DESIGN This study used New York City Vital Statistics birth and death records linked with maternal and newborn discharge abstract data for live births between 2010 and 2014. We included 6901 infants without congenital anomalies born between 240/7 and 326/7 weeks of gestation. Severe maternal morbidity was identified as life-threatening conditions or life-saving procedures. Outcomes were first-year infant mortality, severe neonatal morbidity (bronchopulmonary dysplasia, severe necrotizing enterocolitis, stage 3-5 retinopathy of prematurity, and intraventricular hemorrhage grades 3-4), and a combined outcome of death or morbidity. RESULTS Twelve percent of very preterm live-born infants had a mother with severe maternal morbidity. Maternal and pregnancy characteristics associated with occurrence of severe maternal morbidity were multiparity, being non-Hispanic black, and preexisting health conditions, but gestational age and the percentage small for gestational age did not differ. Infants whose mothers experienced severe maternal morbidity had higher first-year mortality, 11.2% vs 7.7% without severe maternal morbidity, yielding a relative risk of 1.39 (95% CI: 1.14-1.70) after adjustment for maternal characteristics, preexisting comorbidities, pregnancy complications, and hospital factors. Severe neonatal morbidity was not associated with severe maternal morbidity. CONCLUSIONS Severe maternal morbidity is an independent risk factor for mortality in the first year of life among very preterm infants after consideration of other maternal and pregnancy risk factors.

Abstract
OBJECTIVE To assess neonatal and 2-year outcomes for preterm twins born after planned vaginal delivery compared with planned cesarean delivery. METHODS Women with preterm cephalic first twins delivered after preterm labor or preterm prelabor rupture of membranes from 24 0/7 to 34 6/7 weeks of gestation, with both fetuses alive at the beginning of labor, were identified from the national prospective population-based Etude Epidémiologique sur les Petits Ages Gestationnels 2 cohort study. Planned vaginal delivery was defined as vaginal delivery or cesarean delivery performed during labor. Planned cesarean delivery was considered if performed during labor for the indication of preterm twins or before labor whatever the indication. A propensity score analysis was used to compare planned vaginal delivery and planned cesarean delivery. Outcomes analyzed separately for the first and second twins were survival at discharge, survival at discharge without severe morbidity, and survival at 2 years of corrected age without neurosensory impairment. RESULTS Among the 932 women with a twin pregnancy, 549 were excluded mainly as a result of the first twin in noncephalic presentation, cause of delivery other than preterm labor or preterm prelabor rupture of membranes, at least one twin died before labor, and gestational age at delivery less than 24 weeks of gestation. The planned vaginal delivery group included 276 women and the planned cesarean delivery group 107. For first and second twins, survival at discharge (97.7% vs 98.3% and 95.6% vs 97.1%, respectively), survival at discharge without severe morbidity (91.6% vs 88.8% and 90.3% vs 84.5%, respectively), and survival at 2 years of corrected age without neurosensory impairment (96.0% vs 95.4% and 92.9% vs 90.8%, respectively) did not differ significantly between the planned vaginal delivery and planned cesarean delivery groups. Propensity score analysis showed that planned cesarean delivery was not associated with improved outcomes with the caveat that the infrequency of death and disability limited the statistical power of the study to detect potentially clinically meaningful differences between planned modes of delivery. CONCLUSION Planned cesarean delivery for women in preterm labor or with preterm prelabor rupture of membranes was not associated with improved neonatal outcomes or 2-year outcomes.

Abstract
OBJECTIVES To investigate the relation between neonatal intensive care unit (NICU) volume and survival, and neuromotor and sensory disabilities at 2 years in very preterm infants. STUDY DESIGN The EPIPAGE-2 (Etude Epidémiologique sur les Petits Âges Gestationnels-2) national prospective population-based cohort study was used to include 2447 babies born alive in 66 level III hospitals between 24 and 30 completed weeks of gestation in 2011. The outcome was survival without disabilities (levels 2-5 of the Gross Motor Function Classification System for cerebral palsy with or without unilateral or bilateral blindness or deafness). Units were grouped in quartiles according to volume, defined as the annual admissions of very preterm babies. Multivariate logistic regression analyses with population average models were used. RESULTS Survival at discharge was lower in hospitals with lower volumes of neonatal activity (aOR 0.55, 95% CI 0.33-0.91). Survival without neuromotor and sensory disabilities at 2 years increased with hospital volume, from 75% to 80.7% in the highest volume units. After adjustment for gestational age, small for gestational age, sex, maternal age, infertility treatment, multiple pregnancy, principal cause of prematurity, parental socioeconomic status, and mother's country of birth, survival without neuromotor or sensory disabilities was significantly lower in hospitals with a lower volume of neonatal activity (aOR 0.60, 95% CI 0.38-0.95) than in the highest quartile hospitals. CONCLUSIONS These results suggest that lower neonatal intensive care unit volume is associated with lower survival without an increase in disabilities at 2 years. These results could be useful to generate improvements of perinatal regionalization.

Role of Body Mass Index and gestational weight gain on preterm birth and adverse perinatal outcomes. Sci Rep 2019; 9:13093. [PMID: 31511664 PMCID: PMC6739338 DOI: 10.1038/s41598-019-49704-x] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2017] [Accepted: 08/29/2019] [Indexed: 12/22/2022] Open
Abstract
The association of body mass index (BMI) and gestational weight gain (GWG) with preterm birth (PTB) remains controversial in the literature. To evaluate different maternal BMI and GWG categories, according to the initial BMI, in relation to different PTB subtypes and perinatal outcomes, we conducted a secondary analysis of a multicentre cross-sectional study, along with a nested case-control study including PTB from 20 centers in Brazil. Pre-pregnancy underweight was associated with a lower risk of provider-initiated PTB, while overweight and obesity were associated with a higher risk of provider-initiated PTB and a lower risk of spontaneous preterm birth. Insufficient gestational weight gain was associated with a higher prevalence of spontaneous PTB and preterm premature rupture of membranes. Excessive GWG correlated with a higher prevalence of provider-initiated PTB or preterm premature rupture of membranes. Irrespective of the initial BMI, the greater the rate of GWG, the higher the predicted probability of all PTB subtypes, except for spontaneous PTB in underweight women and those with normal BMI. On multivariate analysis, the initial BMI was shown to be the only factor associated with pi-PTB. Briefly, further studies evaluating the risk for PTB should consider that GWG may have a different role depending on the initial BMI and PTB subtype.

Abstract
BACKGROUND To describe the association between maternal hypertension (chronic and gestational, MH) and mortality in very preterm singletons and twins, focusing on how estimates depend on gestational age (GA) and size at birth. METHODS We estimated relative risks of in-hospital death in 12,320 singletons (MH: 22.4%) and 4381 twins (MH: 10.6%) born at 23-29 weeks in the Italian Neonatal Network (89 hospitals, 2008-2016). RESULTS Babies with MH had higher GA and were more frequently small-for-gestational age (SGA), especially singletons. In crude analyses, MH was associated with lower mortality in singletons. In multivariable analyses, the effects of GA and size differed between twins and singletons with and without MH. The best-fitting models included continuous birth weight (rather than SGA) and were stratified by GA. In these models, MH was associated with lower mortality in singletons-but not twins-born after week 25. CONCLUSIONS In this cohort of very preterm infants, the association between MH and mortality differed between singletons and twins and across strata of GA at birth. These estimates cannot be interpreted causally, but suggest that, from a descriptive/predictive standpoint, singletons with MH born after week 25 have lower mortality than singletons born to women without MH.

Abstract
BACKGROUND The management practices of Respiratory Distress Syndrome (RDS) in the newborn have changed over time. We examine the trends in the epidemiology, resource utilization, and outcomes (mortality and bronchopulmonary dysplasia [BPD]) of RDS in preterm neonates ≤34 weeks gestational age (GA) in the United States. METHODS In this retrospective serial cross-sectional study, we used ICD-9 codes to classify preterm infants GA ≤34 weeks between 2003 and 2014 from the National Inpatient Sample as having RDS or not. Trends in the prevalence of infants defined as RDS by ICD-9 code (ICD9-RDS), length of stay, BPD, and mortality were analyzed using Cochran-Armitage and Jonckheere-Terpstra tests and multivariable logistic regression. RESULTS Of 1 526 186 preterm live births with GA ≤34 weeks, 554 409 had ICD9-RDS (260 cases per 1000 live births) with the prevalence increasing from 170 to 361 (Ptrend < 0.001) and associated decrease in all-cause mortality (7.6% to 6.1%; Ptrend < 0.001) from 2003 to 2014. Increased utilization of non-invasive mechanical ventilation (NIMV) (69.5% to 74.3%; Ptrend < 0.001) was associated with decreased invasive mechanical ventilation (IMV) use >96 h (60.4 to 56.6%; Ptrend < 0.001). Exclusive NIMV use increased from 16.8% to 29.1% (Ptrend < 0.0001). BPD incidence decreased from 14% to 12.5% (Ptrend < 0.001). LOS increased from 32 days to 38 days (Ptrend < 0.001) and cost increased from $49,521 to $55,394 (Ptrend < 0.001). CONCLUSION From 2003 to 2014, the assigned ICD9-RDS diagnosis, and utilization of NIMV increased and mortality among infants assigned the ICD9-RDS diagnosis decreased. With higher survival, hospital cost increased incrementally, indicating the importance of ongoing analysis of appropriate reimbursement for the care provided at tertiary centers for preterm infants.

Neonatal Outcomes in Extremely Preterm Newborns Admitted to Intensive Care after No Active Antenatal Management: A Population-Based Cohort Study. J Pediatr 2018; 203:150-155.

Abstract
OBJECTIVE To evaluate the association between active antenatal management and neonatal outcomes in extremely preterm newborns admitted to a neonatal intensive care unit (NICU). STUDY DESIGN This population-based cohort study was conducted in 25 regions of France. Infants born in 2011 between 220/7 and 266/7 weeks of gestation and admitted to a NICU were included. Infants with lethal congenital malformations or death in the delivery room were excluded. A multilevel multivariable analysis was performed, accounting for clustering by mother (multiple pregnancies) and hospital plus individual characteristics, to estimate the association between the main exposure of no active antenatal management (not receiving antenatal corticosteroids, magnesium sulfate, or cesarean delivery for fetal indications) and a composite outcome of death or severe neonatal morbidity (including severe forms of brain or lung injury, retinopathy of prematurity, and necrotizing enterocolitis). RESULTS Among 3046 extremely preterm births, 783 infants were admitted to a NICU. Of these, 138 (18%) did not receive active antenatal management. The risk of death or severe morbidity was significantly higher for infants without active antenatal management (crude OR, 2.60; 95% CI, 1.44-4.66). This finding persisted after adjustment for gestational age (OR, 2.08; 95% CI, 1.19-3.62) and all confounding factors (OR, 1.86; 95% CI, 1.09-3.20). CONCLUSIONS The increased risk of severe neonatal outcomes for extremely preterm babies admitted to a NICU without optimal antenatal management should be considered in individual-level decision making and in the development of professional guidelines for the management of extremely preterm births.

Abstract
BACKGROUND Accurate estimation of fetal weight is needed for growth monitoring and decision-making in obstetrics; the INTERGROWTH project developed an estimated fetal weight formula to construct new intrauterine growth standards. OBJECTIVE We sought to compare the accuracy of the Hadlock and INTERGROWTH formulas for the estimation of fetal weight among preterm infants. STUDY DESIGN Using the EPIPAGE 2 population-based study of births between 22-34 weeks of gestation, we included 578 nonanomalous singleton fetuses with an ultrasound-to-delivery interval <2 days. We used abdominal circumference, head circumference, and femur length to calculate estimated fetal weight with Hadlock formula and abdominal and head circumferences to calculate estimated fetal weight according to INTERGROWTH. The mean percentage errors and the proportions of estimated fetal weight measures within ±10% of birthweight were compared between the 2 methods. RESULTS Mean (SD) gestational age and birthweight were 29.1 (SD 2.7) weeks and 1219 (SD 489) g. Mean (SD) percentage errors for Hadlock and INTERGROWTH were significantly different: -0.7 (SD 10.1) and -3.5 (SD 11.6), respectively (P < .001), and more infants were classified within ±10% of their birthweight with Hadlock compared to INTERGROWTH (68.7% vs 57.8%, P < .001). The INTERGROWTH formula overestimated birthweight at 22-23 weeks compared to Hadlock [mean errors of 18.8 (SD 13.6) vs 5.5 (SD 10.2)] and underestimated birthweight >28 weeks: at 29-31 weeks, mean errors were -5.8 (SD 10.9) for INTERGROWTH and -0.6 (SD 10.4) for Hadlock. CONCLUSION Hadlock estimated fetal weight formula was more accurate than INTERGROWTH formula for fetuses delivered between 22-34 weeks of gestation. Our results support continued use of Hadlock formula in France and raise questions about the applicability of INTERGROWTH intrauterine growth standards.

Abstract
OBJECTIVES To synthetize the available evidence regarding the incidence and risk factors of preterm premature rupture of membranes (PPROM). To describe the evolution of pregnancy, neonatal outcomes and the prognosis of infants born in a context of PPROM, according to the existence of an associated intrauterine infection and to the latency duration. METHOD Consultation of the Medline database, from 1980 to February 2018. RESULTS PPROM before 37 and before 34 weeks' gestation occur in 2-3% and <1% of pregnancies, respectively (LE2). Although many risk factors are identified, few are modifiable, and the vast majority of patients have no risk factors (LE2). Consequently, individual prediction of the risk of PPROM and primary prevention measures have not been shown to be effective and are not recommended in clinical practice (Grade B). Most women give birth within the week following PPROM (LE2). The main complications of PPROM are prematurity, intrauterine infection and obstetric and maternal complications (LE2). Latency duration and the frequency of complications decrease with increasing gestational age at PPROM (LE2). Neonatal prognosis is largely conditioned by gestational age at birth, with no apparent over-risk of poor outcomes linked to PPROM compared to other causes of preterm birth (LE2). In contrast, intrauterine infection is associated with an increased risk of in utero fetal death (LE3), necrotizing enterocolitis (LE1) and early-onset sepsis (LE2). The association of intrauterine infection with neurological morbidity remains controversial. Prolongation of latency, from gestational age at PPROM, is beneficial for the child (LE2). CONCLUSION PPROM is a major cause of prematurity and short- and long-term mortality and morbidity. Antenatal care is an important issue for obstetric and pediatric teams, aiming to reduce complications and adverse consequences for both mother and child.

Abstract
Objective To assess the scores of postpartum women using the WHO Disability Assessment Schedule 2.0 36‐item tool (WHODAS‐36), considering different morbidities. Methods Secondary analysis of a retrospective cohort of women who delivered at a referral maternity in Brazil and were classified with and without severe maternal morbidity (SMM). WHODAS‐36 was used to assess functioning in postpartum women. Percentile distribution of total WHODAS score was compared across three groups: Percentile (P)<10, 10<P<90, and P>90. Cases of SMM were categorized and WHODAS‐36 score was assessed according to hypertension, hemorrhage, or other conditions. Results A total of 638 women were enrolled: 64 had mean scores below P<10 (1.09) and 66 were above P>90 (41.3). Of women scoring above P>90, those with morbidity had a higher mean score than those without (44.6% vs 36.8%, P=0.879). Women with higher WHODAS‐36 scores presented more complications during pregnancy, especially hypertension (47.0% vs 37.5%, P=0.09). Mean scores among women with any complication were higher than those with no morbidity (19.0 vs 14.2, P=0.01). WHODAS‐36 scores were higher among women with hypertensive complications (19.9 vs 16.0, P=0.004), but lower among those with hemorrhagic complications (13.8 vs 17.7, P=0.09). Conclusions Complications during pregnancy, childbirth, and the puerperium increase long‐term WHODAS‐36 scores, demonstrating a persistent impact on functioning among women, up to 5 years postpartum. Women who experienced severe maternal morbidity are at risk of disabilities in the postpartum period, as measured by the WHODAS 2.0 36‐item tool.

Abstract
AIM We studied the impact of maternal and pregnancy-related conditions and the effect of gestational age itself, on the health of infants born late preterm. METHODS Singletons born in gestational weeks 34 + 0 to 41 + 6 in 1995-2013 in the southern region of Sweden were identified from a perinatal register. We found 14 030 infants born late preterm and 294 814 born at term. A hierarchical system was developed to examine the impact of pregnancy complications. The outcomes studied were as follows: neonatal death, central nervous system (CNS) or respiratory disease, infection, neonatal admission and respiratory support. Odds ratios (OR) and 95% confidence intervals (95% CI) were obtained using logistic regression analyses. RESULTS Late preterm infants were at increased risk for all outcomes compared to term infants, with adjusted ORs from 13.1 (95% CI: 12.7-13.6) for neonatal admission to 2.3 (95% CI: 1.8-2.9) for infections. Late preterm birth after preterm prelabour rupture of membranes was associated with an overall lower risk compared to late preterm births due to other causes. Exposure to antepartum haemorrhage or maternal diabetes increased the risk for CNS and respiratory morbidity. CONCLUSION Morbidity decreased in late preterm infants with increasing gestational age. Underlying conditions accounted for a substantial part of the morbidity.

Abstract
Background: A large recent study analyzed the relationship between multiple factors and neonatal outcome and in preterm births. Study variables included the reason for admission, indication for delivery, optimal steroid use, gestational age, and other potential prognostic factors. Using stepwise multivariable analysis, the only two variables independently associated with serious neonatal morbidity were gestational age and the presence of suspected intrauterine growth restriction as a reason for admission. This finding was surprising given the beneficial effects of antenatal steroids and hazards associated with some causes of preterm birth. Multivariable logistic regression techniques have limitations. Without testing for multiple interactions, linear regression will identify only individual factors with the strongest independent relationship to the outcome for the entire study group. There may not be a single "best set" of risk factors or one set that applies equally well to all subgroups. In contrast, machine learning techniques find the most predictive groupings of factors based on their frequency and strength of association, with no attempt to identify independence and no assumptions about linear relationships.Objective: To determine if machine learning techniques would identify specific clusters of conditions with different probability estimates for severe neonatal morbidity and to compare these findings to those based on the original multivariable analysis.Materials and methods: This was a secondary analysis of data collected in a multicenter, prospective study on all admissions to the neonatal intensive care unit between 2013 and 2015 in 10 hospitals. We included all patients with a singleton, stillborn, or live newborns, with a gestational age between 23 0/7 and 31 6/7 week. The composite endpoint, severe neonatal morbidity, defined by the presence of any of five outcomes: death, grade 3 or 4 intraventricular hemorrhage (IVH), and ≥28 days on ventilator, periventricular leukomalacia (PVL), or stage III necrotizing enterocolitis (NEC), was present in 238 of the 1039 study patients. We studied five explanatory variables: maternal age, parity, gestational age, admission reason, and status with respect to antenatal steroid administration. We concentrated on Classification and Regression Trees because the resulting structure defines clusters of risk factors that often bear resemblance to clinical reasoning. Model performance was measured using area under the receiver-operator characteristic curves (AUC) based on 10 repetitions of 10-fold cross-validation.Results: A hybrid technique using a combination of logistic regression and Classification and Regression Trees had a mean cross-validated AUC of 0.853. A selected point on its receiver-operator characteristic (ROC) curve corresponding to a sensitivity of 81% was associated with a specificity of 76%. Rather than a single curve representing the general relationship between gestational age and severe morbidity, this technique found seven clusters with distinct curves. Abnormal fetal testing as a reason for admission with or without growth restriction and incomplete steroid administration would place a 20-year-old patient on the highest risk curve.Conclusions: Using a relatively small database and a few simple factors known before birth it is possible to produce a more tailored estimate of the risk for severe neonatal morbidity on which clinicians can superimpose their medical judgment, experience, and intuition.

Abstract
Background Preterm birth is a major public health problem in developed countries. In this context, we have conducted research into outpatient monitoring of uterine electrical activity in women at risk of preterm delivery. The objective of this preliminary study was to perform automated detection of uterine contractions (without human intervention or tocographic signal, TOCO) by processing the EHG recorded on the abdomen of pregnant women. The feasibility and accuracy of uterine contraction detection based on EHG processing were tested and compared to expert decision using external tocodynamometry (TOCO) . Methods The study protocol was approved by local Ethics Committees under numbers ID-RCB 2016-A00663-48 for France and VSN 02-0006-V2 for Iceland. Two populations of women were included (threatened preterm birth and labour) in order to test our system of recognition of the various types of uterine contractions. EHG signal acquisition was performed according to a standardized protocol to ensure optimal reproducibility of EHG recordings. A system of 18 Ag/AgCl surface electrodes was used by placing 16 recording electrodes between the woman’s pubis and umbilicus according to a 4 × 4 matrix. TOCO was recorded simultaneously with EHG recording. EHG signals were analysed in real-time by calculation of the nonlinear correlation coefficient H2. A curve representing the number of correlated pairs of signals according to the value of H2 calculated between bipolar signals was then plotted. High values of H2 indicated the presence of an event that may correspond to a contraction. Two tests were performed after detection of an event (fusion and elimination of certain events) in order to increase the contraction detection rate. Results The EHG database contained 51 recordings from pregnant women, with a total of 501 contractions previously labelled by analysis of the corresponding tocographic recording. The percentage recognitions obtained by application of the method based on coefficient H2 was 100% with 782% of false alarms. Addition of fusion and elimination tests to the previously obtained detections allowed the false alarm rate to be divided by 8.5, while maintaining an excellent detection rate (96%). Conclusion These preliminary results appear to be encouraging for monitoring of uterine contractions by algorithm-based automated detection to process the electrohysterographic signal (EHG). This compact recording system, based on the use of surface electrodes attached to the skin, appears to be particularly suitable for outpatient monitoring of uterine contractions, possibly at home, allowing telemonitoring of pregnancies. One of the advantages of EHG processing is that useful information concerning contraction efficiency can be extracted from this signal, which is not possible with the TOCO signal.

Abstract
OBJECTIVE To describe survival rate after preterm premature rupture of membranes (PPROM) before 25 weeks of gestation and compare neonatal morbidity and mortality among those born alive with a control group of infants born at a similar gestational age without premature rupture of membranes. METHODS We conducted a retrospective single-centre study at Port-Royal maternity, from 2007 to 2015, comparing neonatal outcomes between liveborninfants exposed to PPROM prior to 25 weeks of gestation (WG) and a control group not exposed to premature rupture of the membranes. For each live-born child, the next child born after spontaneous labor without PPROM was matched for gestational age at birth, sex, and whether or not they received antenatal corticosteroid therapy. The primary endpoint was severe neonatal complications assessed by a composite endpoint including neonatal deaths, grade 3-4 HIV, bronchopulmonary dysplasia, leukomalacia and stade 3-4 retinopathies. RESULTS Among 77 cases of very premature rupture of the membranes, 55 children were born alive. Among these, the average gestational age at birth was 28 WG and 1 day. The rate of severe neonatal complications did not differ between the two groups (43.6% in the PPROM group vs. 36.4%, P=0.44) and the survival rate at discharge was also similar in the two groups (85.5% vs. 83.6%, P=0.98). CONCLUSIONS In our cohort and among livebirths after 24 WG, PPROM before 25 WG was not associated with an increased risk of morbidity and mortality compared to children born at the same gestational age after a spontaneous labor with intact membranes.

Abstract
AIM This study evaluated the role of preterm birth and fetal growth restriction on white matter maturation in schoolchildren without any severe neurodevelopmental impairment. METHODS The study group comprised 56 very preterm children and 21 term children born between November 1998 and November 2002 at Oulu University Hospital, Finland. The mean gestational age of the preterm children was 28.7 (24.1-31.9) weeks. All children underwent diffusion tensor imaging at a mean age of 9.0 (8.6-9.6) years. Voxel-wise statistical analyses of the imaging data were carried out using tract-based spatial statistics. RESULTS Preterm children with fetal growth restriction had lower fractional anisotropy and higher radial diffusivity than term controls (p < 0.05), bilaterally in several white matter areas. Preterm children without fetal growth restriction had higher mean diffusivity and axial diffusivity than term controls (p < 0.05) in analogous areas, but more asymmetrically. CONCLUSION Preterm children had microstructural differences in white matter, compared to term-born children at a mean age of nine, and those with poor fetal growth showed widespread changes in white matter maturation compared to term-born children. Fetal growth and prematurity seemed to affect white matter maturation in a way that was still visible at that age.

Abstract
Objective Risk factors for placental abruption have changed, but there has not been an updated systematic review investigating outcomes. Methods We searched PubMed, EMBASE, Web of Science, SCOPUS, and CINAHL for publications from January 1, 2005 through December 31, 2016. We reviewed English-language publications reporting estimated incidence and/or risk factors for maternal, labor, delivery, and perinatal outcomes associated with abruption. We excluded case studies, conference abstracts, and studies that lacked a referent/comparison group or did not clearly characterize placental abruption. Results A total of 123 studies were included. Abruption was associated with elevated risk of cesarean delivery, postpartum hemorrhage and transfusion, preterm birth, intrauterine growth restriction or low birth weight, perinatal mortality, and cerebral palsy. Additional maternal outcomes included relaparotomy, hysterectomy, sepsis, amniotic fluid embolism, venous thromboembolism, acute kidney injury, and maternal intensive care unit admission. Additional perinatal outcomes included acidosis, encephalopathy, severe respiratory disorders, necrotizing enterocolitis, acute kidney injury, need for resuscitation, chronic lung disease, infant death, and epilepsy. Conclusion Few studies examined outcomes beyond the initial birth period, but there is evidence that both mother and child are at risk of additional adverse outcomes. There was also considerable variation in, or absence of, the reporting of abruption definitions.

Abstract
OBJECTIVE To investigate the association between histologic chorioamnionitis (HCA) and bronchopulmonary dysplasia (BPD) in very preterm infants, both in a general population and for those born after spontaneous preterm labor and after preterm premature rupture of membranes (pPROM). STUDY DESIGN This study included 2513 live born singletons delivered at 24-31 weeks of gestation from a national prospective population-based cohort of preterm births; 1731 placenta reports were available. HCA was defined as neutrophil infiltrates in the amnion, chorion of the membranes, or chorionic plate, associated or not with funisitis. The main outcome measure was moderate or severe BPD. Analyses involved logistic regressions and multiple imputation for missing data. RESULTS The incidence of HCA was 28.4% overall: 38% in cases of preterm labor, 64% in cases of pPROM, and less than 5% in cases of vascular disorders. Overall, the risk of BPD after adjustment for gestational age, sex, and antenatal steroids was reduced for infants with HCA (HCA alone: aOR 0.6 [95% CI 0.4-0.9]; associated with funisitis: aOR 0.5 [95% CI 0.3-0.8]). This finding was explained by the high rate of BPD and low rate of chorioamnionitis among children with fetal growth restriction. HCA was not associated with BPD in the preterm labor (13.4% vs 8.5%; aOR 0.9; 95% CI 0.5-1.8) or in the pPROM group (12.9% vs 12.1%; aOR 0.6; 95% CI 0.3-1.3). CONCLUSION In homogeneous groups of infants born after preterm labor or pPROM, HCA is not associated with BPD.

Abstract
BACKGROUND Counseling for patients with impending premature delivery traditionally has been based primarily on the projected gestational age at delivery. There are limited data regarding how the indications for the preterm birth affect the neonatal outcome and whether this issue should be taken into account in decisions regarding management and patient counseling. OBJECTIVE We performed a prospective study of pregnancies resulting in premature delivery at less than 32 weeks to determine the influence of both the indications for admission and their associated indications for delivery on neonatal mortality and complications of prematurity. STUDY DESIGN This is a multicenter, prospective study in 10 hospitals where all data from the neonatal intensive care unit routinely was imported to a deidentified data warehouse. Maternal data were collected prospectively at or near the time of delivery. Eligible subjects included singleton deliveries in these hospitals between 23 0/7 and 31 6/7 weeks. The primary hypothesis of the study was to determine whether there was a difference in the primary outcome, which was defined as neonatal composite morbidity, between those neonates delivered after admission for premature labor vs premature rupture of membranes, because these were expected to be the 2 most frequent diagnoses leading to premature birth. The sample size was calculated based on a 10% difference in outcomes for these 2 entities. We based this hypothesis on the knowledge that premature rupture of membranes has a greater incidence of intra-amniotic infection and inflammation than premature labor and that outcomes for premature neonates are worse when delivery is associated with intra-amniotic infection. Additional outcomes were analyzed for all other indications for admission and delivery. Composite morbidity was defined as ≥1 of the following: respiratory distress syndrome (oxygen requirement, clinical diagnosis, and consistent chest radiograph), bronchopulmonary dysplasia (requirement for oxygen support at 28 days of life), severe intraventricular hemorrhage (grades 3 or 4), periventricular leukomalacia, blood culture-proven sepsis present within 72 hours of birth, necrotizing enterocolitis, or neonatal death before discharge from the hospital. A secondary composite of serious neonatal morbidity also was defined prospectively. RESULTS The study included 1089 mother/baby pairs. Composite morbidity between those with premature labor (77.2%) and premature rupture of membranes (73.2%) was not significantly different (P = .29). A few neonatal complications were associated with indications for admission and delivery, but on logistic regression adjusting for gestational age and other confounders, suspected intrauterine growth restriction was the only indication for admission or delivery associated with an increase in serious morbidity (odds ratio 4.5, [2.1 to 9.8], P < .003). Other factors not related to the indications for admission including cesarean delivery, and low 5-minute Apgar were associated with an increase in morbidity. CONCLUSION Studies of many single factors related to the indications for preterm delivery have been shown to be associated with adverse neonatal outcome. In this study evaluating all of the most frequent indications, however, we found only suspected intrauterine growth restriction as an indication for admission and delivery was found to be so. Thus, it seems that in almost all situations counseling patients can be based primarily on gestational age along with other factors including estimated fetal weight, sex, race, plurality, and completion of a course of antenatal corticosteroids.

Abstract
BACKGROUND Intraventricular hemorrhage is a major risk factor for neurodevelopmental disabilities in preterm infants. However, few studies have investigated how pregnancy complications responsible for preterm delivery are related to intraventricular hemorrhage. OBJECTIVE We sought to investigate the association between the main causes of preterm delivery and intraventricular hemorrhage in very preterm infants born in France during 2011 between 22-31 weeks of gestation. STUDY DESIGN The study included 3495 preterm infants from the national EPIPAGE 2 cohort study who were admitted to neonatal intensive care units and had at least 1 cranial ultrasound assessment. The primary outcome was grade I-IV intraventricular hemorrhage according to the Papile classification. Multinomial logistic regression models were used to study the relationship between risk of intraventricular hemorrhage and the leading causes of preterm delivery: vascular placental diseases, isolated intrauterine growth retardation, placental abruption, preterm labor, and premature rupture of membranes, with or without associated maternal inflammatory syndrome. RESULTS The overall frequency of grade IV, III, II, and I intraventricular hemorrhage was 3.8% (95% confidence interval, 3.2-4.5), 3.3% (95% confidence interval, 2.7-3.9), 12.1% (95% confidence interval, 11.0-13.3), and 17.0% (95% confidence interval, 15.7-18.4), respectively. After adjustment for gestational age, antenatal magnesium sulfate therapy, level of care in the maternity unit, antenatal corticosteroids, and chest compressions, infants born after placental abruption had a higher risk of grade IV and III intraventricular hemorrhage compared to those born under placental vascular disease conditions, with adjusted odds ratios of 4.3 (95% confidence interval, 1.1-17.0) and 4.4 (95% confidence interval, 1.1-17.6), respectively. Similarly, preterm labor with concurrent inflammatory syndrome was associated with an increased risk of grade IV intraventricular hemorrhage (adjusted odds ratio, 3.4; 95% confidence interval, 1.1-10.2]). Premature rupture of membranes did not significantly increase the risk. CONCLUSION Relationships between the causes of preterm birth and intraventricular hemorrhage were limited to specific and rare cases involving acute hypoxia-ischemia and/or inflammation. While the emergent nature of placental abruption would challenge any attempts to optimize management, the prenatal care offered during preterm labor could be improved.

Abstract
BACKGROUND Fetal growth restriction is defined using ultrasound parameters during pregnancy or as a low birthweight for gestational age after birth, but these definitions are not always concordant. OBJECTIVE The purpose of this study was to investigate fetal and neonatal outcomes based on antenatal vs postnatal assessments of growth restriction. STUDY DESIGN From the EPIPAGE 2 population-based prospective study of very preterm births in France in 2011, we included 2919 singleton nonanomalous infants 24-31 weeks gestational age. We constituted 4 groups based on whether the infant was suspected with fetal growth restriction during pregnancy and/or was small for gestational age with a birthweight <10th percentile of intrauterine norms by sex: 1) suspected with fetal growth restriction/small for gestational age 2) not suspected with fetal growth restriction/small for gestational age 3) suspected with fetal growth restriction/not small for gestational age and 4) not suspected with fetal growth restriction/not small for gestational age. We estimated relative risks of perinatal mortality and morbidity for these groups adjusting for maternal and neonatal characteristics. RESULTS We found that 22.2% of infants were suspected with fetal growth restriction/small for gestational age, that 11.4% infants were not suspected with fetal growth restriction/small for gestational age, that 3.0% infants were suspected with fetal growth restriction/not small for gestational age, and that 63.4% infants were not suspected with fetal growth restriction/not small for gestational age. Compared with infants who were not suspected with fetal growth restriction/not small-for-gestational-age infants, small-for-gestational-age infants suspected and not suspected with fetal growth restriction had higher risks of stillbirth or termination of pregnancy (adjusted relative risk, 2.0 [95% confidence interval, 1.6-2.5] and adjusted relative risk, 2.8 [95% confidence interval, 2.2-3.4], respectively), in-hospital death (adjusted relative risk, 2.8 [95% confidence interval, 2.0-3.7] and adjusted relative risk, 2.0 [95% confidence interval, 1.5-2.8], respectively), and bronchopulmonary dysplasia (adjusted relative risk, 1.3 [95% confidence interval, 1.2-1.4] and adjusted relative risk, 1.3 [95% confidence interval, 1.1-1.4], respectively), but not severe brain lesions. Risks were not increased for infants suspected with fetal growth restriction but not small-for-gestational-age. CONCLUSION Antenatal and postnatal assessments of fetal growth restriction were not concordant for 14% of very preterm infants. In these cases, birthweight appears to be the more relevant parameter for the identification of infants with higher risks of adverse short-term outcomes.
