Abstract
OBJECTIVE Data from the academic medical centers in the United States showing improvements in survival of periviable infants born at 22 to 24 weeks GA may not be nationally representative since a substantial proportion of preterm infants are cared for in community hospital-based neonatal intensive care units. Our objective was to examine the national trends in survival and other short-term outcomes among preterm infants born at ≤24 weeks gestational age (GA) in the United States from 2009 to 2018. STUDY DESIGN This was a retrospective, repeated cross-sectional analysis of the National Inpatient Sample for preterm infants ≤24 weeks GA. The primary outcome was the trends in survival to discharge. Secondary outcomes were the trends in the composite outcome of death or one or more major morbidity (bronchopulmonary dysplasia, necrotizing enterocolitis stage ≥2, periventricular leukomalacia, severe intraventricular hemorrhage, and severe retinopathy of prematurity). The Cochran-Armitage trend test was used for trend analysis. p-Value <0.05 was considered significant. RESULTS Among 71,854 infants born at ≤24 weeks GA, 34,251 (47.6%) survived less than 1 day and were excluded. Almost 93% of those who survived <1 day were of ≤23 weeks GA. Among the 37,603 infants included in the study cohort, 48.1% were born at 24 weeks GA. Survival to discharge at GA ≤ 23 weeks increased from 29.6% in 2009 to 41.7% in 2018 (p < 0.001), while survival to discharge at GA 24 weeks increased from 58.3 to 65.9% (p < 0.001). There was a significant decline in the secondary outcomes among all the periviable infants who survived ≥1 day of life. CONCLUSION Survival to discharge among preterm infants ≤24 weeks GA significantly increased, while death or major morbidities significantly decreased from 2009 to 2018. The postdischarge survival, health care resource use, and long neurodevelopmental outcomes of these infants need further investigation. KEY POINTS · Survival increased significantly in infants ≤24 weeks GA in the United States from 2009 to 2018.. · Death or major morbidity in infants ≤24 weeks GA decreased significantly from 2009 to 2018.. · Death or surgical procedures including tracheostomy, VP shunt placement, and PDA surgical closure in infants <=24 weeks GA decreased significantly from 2009 to 2018..

Abstract
Fetal lung development is a crucial and complex process that lays the groundwork for postnatal respiratory health. However, disruptions in this delicate developmental journey can lead to fetal lung development disorders, impacting neonatal outcomes and potentially influencing health outcomes well into adulthood. Recent research has shed light on the intriguing association between fetal lung development disorders and the development of adult diseases. Understanding these links can provide valuable insights into the developmental origins of health and disease, paving the way for targeted preventive measures and clinical interventions. This review article aims to comprehensively explore the association of fetal lung development disorders with adult diseases. We delve into the stages of fetal lung development, examining key factors influencing fetal lung maturation. Subsequently, we investigate specific fetal lung development disorders, such as respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD), congenital diaphragmatic hernia (CDH), and other abnormalities. Furthermore, we explore the potential mechanisms underlying these associations, considering the role of epigenetic modifications, transgenerational effects, and intrauterine environmental factors. Additionally, we examine the epidemiological evidence and clinical findings linking fetal lung development disorders to adult respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), and other respiratory ailments. This review provides valuable insights for healthcare professionals and researchers, guiding future investigations and shaping strategies for preventive interventions and long-term care.

Abstract
OBJECTIVES To evaluate the incidence and modifiable risk factors for Necrotizing enterocolitis (NEC) in preterm infants born at ≤32 weeks of gestation weighing <1500 grams, at a private tertiary care hospital in Kenya. MATERIALS AND METHODS This retrospective cohort study was conducted at the Aga Khan University Hospital Neonatal Intensive Care Unit (NICU). Preterm infants born at ≤ 32 weeks' gestation and weighing <1500 grams admitted to NICU between 2009 and 2019, were recruited into the study. The primary outcome was NEC Bell Stage IIa-IIIb based on Modified Bell's criteria. Maternal and neonatal characteristics were evaluated. The association between variables of interest and NEC was determined using logistic regression analysis and the incidence of NEC for the study period was calculated. RESULTS A total of 261 charts of infants born at ≤ 32 weeks' gestation, weighing <1500 were reviewed, and 200 charts met the inclusion criteria. Fifteen preterm infants developed the primary outcome of interest: NEC Stage ≥2a within the first 30 days of admission. The overall incidence of NEC for the study period was 7.5%. Three risk factors were identified as significantly associated with NEC on multivariate logistic regression analysis: antenatal exposure to steroids (OR = 0.056 CI = 0.003-0.964 p = 0.047), cumulative duration of exposure to invasive mechanical ventilation (OR = 2.172 CI = 1.242-3.799 p = 0.007) and cumulative duration of exposure to umbilical vein catheter (OR = 1.344 CI = 1.08-1.672 p = 0.008). CONCLUSIONS The overall incidence for the study period of NEC Stage ≥ II a was 7.5%. Exposure to antenatal steroids, duration of mechanical ventilation, and duration of umbilical vein catheterization were three independent modifiable risk factors for NEC Stage II a-Stage III b.

Abstract
OBJECTIVE We aimed to present the active management and outcomes of infants born at 22 weeks of gestation. STUDY DESIGN This retrospective observational study presented the resuscitation methods, management during hospitalization, and outcomes of 29 infants born at 22 weeks of gestation who were actively resuscitated and admitted to our center during 2013-2020. RESULTS The survival rate was 82.8% (24/29). Tracheal intubation was performed in all patients, and surfactant was administered for 27 (93.1%). Conventional mechanical ventilation was introduced in 27 (93.1%), and this was changed to high-frequency oscillatory ventilation in more than half by day 4. Surgical treatments of patent ductus arteriosus, necrotizing enterocolitis, and retinopathy of prematurity were required in 4 (13.7%), 3 (10.3%), and 15 (51.7%) patients, respectively. No patient required a tracheostomy or ventriculoperitoneal shunt. CONCLUSIONS The overall survival rate and survival rate without morbidities were high among infants born at 22 weeks of gestation.

Abstract
Outcomes for extremely low gestational age newborns (ELGANs), defined as <28 weeks estimated gestational age (EGA), remain disproportionately poor. A radical paradigm shift in the treatment of prematurity is to recreate the fetal environment with extracorporeal support and provide an environment for organ maturation using an extracorporeal VV-ECLS artificial placenta (AP) or an AV-ECLS artificial womb (AW). In this article, we will review clinical indications, current approaches in development, ongoing challenges, remaining milestones and ethical considerations prior to clinical translation.

Abstract
OBJECTIVES To study the association between antenatal corticosteroids treatment and childhood mental disorders in infants born at different gestational ages, and to investigate the effect of different administration timing. STUDY DESIGN This population-based cohort study used data from the Taiwan National Health Insurance Research Database. All singleton live births born between 2004 and 2010 were enrolled and followed up for at least 6 years. The primary outcome was any childhood mental disorder. Secondary outcomes included 7 specific subgroups of mental disorders. RESULTS A total of 1 163 443 singleton infants were included in the analysis, and 16 847 (1.45%) infants were exposed to antenatal corticosteroid treatment. Children exposed to antenatal corticosteroids were found to have a higher risk of developing childhood mental disorders in the entire cohort (hazard ratio [HR], 1.13; 95% CI, 1.08-1.18), the term group (HR, 1.11; 95% CI, 1.05-1.16), and the late-preterm group (HR, 1.15; 95% CI, 1.06-1.25). The administration of corticosteroids in the early stage of pregnancy (<28 weeks of gestation) significantly increased the risk of childhood mental disorders (HR, 1.22; 95% CI, 1.14-1.31). CONCLUSIONS Exposure to antenatal corticosteroid treatment increases the cumulative risk of childhood mental disorders and attention deficit hyperactivity disorders, both in term and late preterm infants. The administration of corticosteroids in the early stage of pregnancy tends to increase the risk of mental disorders.

Abstract
BACKGROUND Very-low-birthweight (VLBW) infants can experience severe intraventricular hemorrhage (IVH) that can lead to life-long disability by impairing neurodevelopment. The aim of this study was to identify the risk and protective factors for severe IVH in VLBW infants. METHODS A retrospective, cross-sectional review of VLBW infants born at 22-28 weeks' gestation between January 2003 and December 2012 and listed in the Database of Neonatal Research Network in Japan was performed using a statistical model incorporating an odds ratio (OR) and medical center variation as a center variance ratio (CVR). A two-dimensional analysis using a combination of OR and the CVR described evolving measures of a clinical trial (for OR > 1) and standardization (for CVR > 1) concerning a factor of interest. RESULTS The noteworthy significant protective factors were antenatal steroids (ANS) with and without premature rupture of membrane (OR: 0.43, CVR: 1.08, and OR: 0.68, CVR: 1.14, respectively) and the number of neonatal beds (OR: 0.94, CVR: 0.99) and staff nurses per neonatal bed (OR: 0.89, CVR: 0.99). CONCLUSIONS Active promotion of ANS administration and consolidation of perinatal medical centers can mitigate the development of severe IVH in VLBW infants.

Abstract
INTRODUCTION The 2021-updated guidelines of the Spanish Society of Neonatology Guidelines have moved the zone of parental discretion to 23 + 0-23 + 6 weeks. The objective of this study was to describe the changes in perinatal management at this gestational age along the last decade and to determine if a more active perinatal management has contributed to improved outcomes. METHODS Retrospective analysis of prospectively collected data from the 23-week infants included in the Spanish SEN 1500 neonatal network during the period 2010-2019. The main study outcomes were survival at discharge and survival without major morbidity of actively managed infants. Two periods were compared: 2010-2014 (Period 1) and 2015-2019 (Period 2). NICUs were classified into low activity NICUs (less than 50 admissions of very low birth weight infants per year) and high activity NICUs (50 or more admissions). RESULTS A total of 381 infants were included, 182 in Period 1 and 199 in Period 2. In Period 2 an increase in the use of intrapartum magnesium sulfate (21.5% vs 39.9%, p .002), antenatal steroids (56.6% vs 69.3%, p .011) and active neonatal approach in delivery room (76.9% vs 86.9%, p .011) were observed.The clinical outcomes of the actively managed 313 infants were similar in both periods, except for less arterial hypotension in Period 2. Survival was 27.1% in Period 1 and 25% in Period 2 (p .068) and survival without major morbidity was 2.1% and 2.3% respectively (p .914). No difference was found between low and high activity NICUs. CONCLUSION A change to a more active intention to treat infants born at 23 weeks is taking place in Spain. But the survival rate of the actively-managed infants has remained stable around 25-30% during the study period. A multidisciplinary effort is needed to improve outcomes in this population.

Abstract
OBJECTIVE To determine the rate and trend of active treatment in a population-based cohort of infants born at 22-25 weeks of gestation and to examine factors associated with active treatment. STUDY DESIGN This observational study evaluated 8247 infants born at 22-25 weeks of gestation at hospitals in the California Perinatal Quality Care Collaborative between 2011 and 2018. Multivariable logistic regression was used to relate maternal demographic and prenatal factors, fetal characteristics, and hospital level of care to the primary outcome of active treatment. RESULTS Active treatment was provided to 6657 infants. The rate at 22 weeks was 19.4% and increased with each advancing week, and was significantly higher for infants born between days 4 and 6 at 22 or 23 weeks of gestation compared with those born between days 0 and 3 (26.2% and 78.3%, respectively, vs 14.1% and 65.9%, respectively; P < .001). The rate of active treatment at 23 weeks increased from 2011 to 2018 (from 64.9% to 83.4%; P < .0001) but did not change significantly at 22 weeks. Factors associated with increased odds of active treatment included maternal Hispanic ethnicity and Black race, preterm premature rupture of membranes, obstetrical bleeding, antenatal steroids, and cesarean delivery. Factors associated with decreased odds included lower gestational age and small for gestational age birth weight. CONCLUSIONS In California, active treatment rates at 23 weeks of gestation increased between 2011 and 2018, but rates at 22 weeks did not. At 22 and 23 weeks, rates increased during the latter part of the week. Several maternal and infant factors were associated with the likelihood of active treatment.

Abstract
Advances in ventilation strategies for infants in the NICU have led to increased survival of extremely preterm infants. More than 75% of infants born at less than or equal to 27 weeks' gestation require initial mechanical ventilation for survival due to developmental immaturity of their lungs and respiratory drive. Various ventilators using different technologies and involving multiple management strategies are available for use in this population. Centers across the world have successfully used conventional, high-frequency oscillatory and high-frequency jet ventilation to manage respiratory failure in extremely preterm infants. This review explores the existing evidence for each mode of ventilation and the importance of individualizing ventilator management strategies when caring for extremely preterm infants.

Importance The provision of antenatal corticosteroids to pregnant patients at gestational age (GA) 22 6/7 weeks or less remains controversial and lacks support from randomized clinical trials. Objective To compare rates of survival and survival without major morbidities among infants born at GA 22 0/7 to 23 6/7 weeks after exposure to antenatal steroids at 22 6/7 weeks' gestation or less vs no exposure to antenatal steroids. Design, Setting, and Participants This cohort study enrolled infants born at GA 22 0/7 to 23 6/7 weeks between January 1, 2016, and December 31, 2019, at centers in the National Institute of Child Health and Human Development Neonatal Research Network. Infants who did not receive intensive care and infants with antenatal steroid exposure after GA 22 6/7 weeks were excluded. Exposure Infants were classified as having no, partial, or complete exposure to antenatal steroids. Main Outcomes and Measures The primary outcome was survival to discharge. The main secondary outcome was survival without major neonatal morbidity. The associations of differential exposures to antenatal steroids with outcomes were evaluated using logistic regression, adjusting for GA, sex, race, maternal education, small for GA status, mode of delivery, multiple birth, prolonged rupture of membranes, year of birth, and Neonatal Research Network center. Results A total of 431 infants (mean [SD] GA, 22.6 [0.5] weeks; 232 [53.8%] boys) were included, with 110 infants (25.5%) receiving no antenatal steroids, 80 infants (18.6%) receiving partial antenatal steroids, and 241 infants (55.9%) receiving complete antenatal steroids. Seventeen infants were exposed to antenatal steroids at GA 21 weeks. Among infants exposed to complete antenatal steroids, 130 (53.9%) survived to discharge, compared with 30 infants (37.5%) with partial antenatal steroid exposure and 239 infants (35.5%) with no antenatal steroids. Infants born after complete antenatal steroid exposure, compared with those without antenatal steroid exposure, were more likely to survive to discharge (adjusted odds ratio [aOR], 1.95 [95% CI, 1.07-3.56]) and to survive without major morbidity (aOR, 2.74 [95% CI, 1.19-6.30]). Conclusions and Relevance In this retrospective cohort study, among infants born between GA 22 0/7 and 23 6/7 weeks who received intensive care, exposure to a complete course of antenatal steroids at GA 22 6/7 weeks or less was independently associated with greater odds of survival and survival without major morbidity. These data suggest that the use of antenatal steroids in patients at GA 22 6/7 weeks or less could be beneficial when active treatment is considered.

Timing of antenatal steroid administration for imminent preterm birth: results of a prospective observational study in Germany. Arch Gynecol Obstet 2022:10.1007/s00404-022-06724-9. [PMID: 36042053 DOI: 10.1007/s00404-022-06724-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 07/25/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE To evaluate the timing of antenatal steroid administration and associated medical interventions in women with imminent preterm birth. METHODS We performed a prospective observational study at a single tertiary center in Germany from September 2018 to August 2019. We included pregnant women who received antenatal steroids for imminent preterm birth and evaluated the interval from administration to birth. 120 women with antenatal steroid application were included into our analysis. Descriptive statistics were performed to analyze factors influencing the timing of antenatal steroids and to evaluate additional medical interventions which women with imminent preterm birth experience. RESULTS Of the 120 women included into our study, 35.8% gave birth before 34/0 weeks and 64.2% before 37/0 weeks of gestation. Only 25/120 women (20.8%) delivered within the optimal time window of 1-7 days after antenatal steroid application. 5/120 women (4.2%) only received one dose of antenatal steroids before birth and 3/120 (2.5%) gave birth within 8 to 14 days after antenatal steroids. Most women gave birth more than 14 days after steroid application (72.5%, 87/120). Women with preeclampsia (60%), PPROM (31%), and FGR (30%) had the highest rates of delivery within the optimal time window. Women of all timing groups received additional interventions and medications like antibiotics, tocolytics, or anticoagulation. CONCLUSION Our observational data indicate that most pregnant women do not give birth within 7 days after the administration of antenatal steroids. The timing was best for preterm birth due to preeclampsia, PPROM, and FGR. Especially for women with symptoms of preterm labor and bleeding placenta previa, antenatal steroids should be indicated more restrictively to improve neonatal outcome and reduce untimely and unnecessary interventions.

Abstract
Being born preterm (prior to 37 weeks of completed gestation) is a leading cause of childhood death up to five years of age, and is responsible for the demise of around one million preterm infants each year. Rates of prematurity, which range from approximately 5 to 18% of births, are increasing in most countries. Babies born extremely preterm (less than 28 weeks' gestation) and in particular, in the periviable (200/7-256/7 weeks) period, are at the highest risk of death, or the development of long-term disabilities. The perinatal care of extremely preterm infants and their mothers raises a number of clinical, technical, and ethical challenges. Focusing on 'micropremmies', or those born in the periviable period, this paper provides an update regarding the aetiology and impacts of periviable preterm birth, advances in the antenatal, intrapartum, and acute post-natal management of these infants, and a review of counselling/support approaches for engaging with the infant's family. It concludes with an overview of emerging technology that may assist in improving outcomes for this at-risk population.

Abstract
PURPOSE OF REVIEW Ventilation of periviable infants born at 22-23 weeks gestation remains a challenge in neonatology. This review highlights the evidence surrounding the use of first intention high-frequency jet ventilation (HFJV) in infants born near the limits of viability with a review of pulmonary fetal development and a focused overview of HFJV strategies including an in-depth analysis of the management strategies used in the initial randomized trials. RECENT FINDINGS A paucity of recent trials exists, with no randomized control trials assessing the use of first intention HFJV performed in the last 25 years. A retrospective observational cohort trial of the use of HFJV for infants born at less than 750 g has been recently published demonstrating the efficacy of HFJV for this population even with 2.0-mm endotracheal tubes. SUMMARY The lack of recent randomized trials contributes to the controversy surrounding the use of first intention HFJV. Although new research is needed in the area, this review includes the ventilation strategy of an experienced center with a focus on the use of first intention HFJV for the care of premature infants born less than 24 weeks gestation.

Abstract
The administration of a single course of corticosteroids before week 34 + 0 of gestation in cases with impending preterm birth is now standard procedure in obstetric care and firmly
established in the guidelines of different countries. But despite the apparently convincing data, numerous aspects of this intervention have not yet been properly studied. It is still not
clear which corticosteroid achieves the best results. There are very few studies on what constitutes an appropriate dose, circadian rhythms, the time frame in which corticosteroids are
effective, and the balance between the risks and benefits of repeat administration. As the existing studies have rarely included patients before week 24 + 0 of gestation, we have very little
information on the possible benefits of administering corticosteroids before this timepoint. If corticosteroids are administered antenatally after week 34 + 0 of gestation, the short-term
benefit may be offset by the long-term adverse effect on psychomotor development. This present study summarizes the current state of knowledge regarding these issues.

Abstract
AIM The aim of the study is to evaluate the influence of the timing of antenatal steroids (ANSs) on neonatal outcome of very low birth weight infants (VLBWI) born before 30 weeks of gestation in the German Neonatal Network. METHODS The German Neonatal Network is a large population-based cohort study enrolling VLBWIs since 2009. We included 672 neonates, who were born between January 1, 2009 and December 31, 2019 in our analysis in 10 selected centers. Infants were divided into four subgroups based on the interval between the first steroid administration and preterm birth: (I) two doses of betamethasone, ANS-birth interval: >24 h to 7 days, n = 187, (II) only one dose of betamethasone, ANS-birth interval 0-24 h, n = 70, (III) two doses of betamethasone, ANS-birth interval >7 days, n = 177, and (IV) no antenatal steroids, n = 238. Descriptive statistics and logistic regression analyses were performed for the main neonatal outcome parameters. Group IV (no ANS) was used as a reference. RESULTS An ANS-birth interval of 24 h to 7 days after the first dose was associated with a reduced risk for intraventricular hemorrhage (OR 0.17; 95% CI 0.09-0.31, p < 0.001) and mechanical ventilation (OR 0.37; 95% CI 0.23-0.61, p < 0.001), whereas the group of infants that only received a single dose of steroids reflected a subgroup at high risk for adverse neonatal outcomes; an ANS-birth interval of >7 days was still associated with a lower risk for intraventricular hemorrhage (OR 0.43; 95% CI 0.25-0.72, p = 0.002) and the need for mechanical ventilation (OR 0.43; 95% CI 0.27-0.71, p = 0.001). CONCLUSION Our observational data indicate that an ANS-birth interval of 24 h to 7 days is strongly associated with a reduced risk of intraventricular hemorrhage in VLBWIs. Further research is needed to improve the prediction of preterm birth in order to achieve a timely administration of antenatal steroids that may improve neonatal outcomes such as intraventricular hemorrhage.

Abstract
OBJECTIVES To compare survival and short-term respiratory outcomes of infants weighing <750 g initially intubated with 2.0 mm versus 2.5 mm endotracheal tube (ETT). STUDY DESIGN Retrospective, observational cohort study. RESULTS Of 149 inborn infants weighing <750 g admitted to the NICU, 69 (46%) were intubated with 2.0 mm ETT, 78 with 2.5 mm ETT (53%), and 2 infants never required intubation. Infants intubated with 2.0 mm ETT were more premature (median gestational age (GA) 23 weeks (22, 24) vs. 24 weeks (24, 25) p < 0.0001), smaller (median birth weight 545 g (450, 616) vs. 648 g (579, 700), p < 0.0001), and more frequently intubated at delivery (96% vs. 68%, p < 0.00001). Survival to discharge was similar 77%, 53/69 and 87%, 68/78 (p = 0.09). Adjusted for GA, there were no significant differences in ventilator days (p = 0.7338) or Grade 3 BPD. CONCLUSIONS Premature infants born at a median GA of 23 weeks and median birth weight of 545 g can be successfully managed with 2.0 mm ETT.

Abstract
BACKGROUND At present, the conclusions about the impact of hypertensive disorders of pregnancy (HDP) on the clinical outcomes of preterm infants are inconsistent. This study used the propensity score matching (PSM) analysis to evaluate the effect of HDP on clinical outcomes of extremely preterm or extremely low birth weight (EP/ELBW) infants. METHODS Retrospective analysis was performed on the EP/ELBW infants discharged from 26 tertiary neonatal intensive care units or died during hospitalization from 2008 to 2017, who were divided into HDP group and non-HDP group. The six covariates including sex, gestational age, birth weight, twin or multiple pregnancy, antenatal steroids administration, and conception method were matched through the PSM method at a ratio of 1:1. The survival rate at discharge and the major clinical complications were compared between the two groups. RESULTS After matching the six covariates, compared with the non-HDP group, there was no significant difference in the survival rate at discharge (64 vs. 63.2%, p > 0.05), the incidence of bronchopulmonary dysplasia (BPD) or moderate to severe BPD in the HDP group (58.3 vs. 54.9%, p > 0.05; 5.2 vs. 6.2%, p > 0.05). The incidence of periventricular leukomalacia (PVL) in the HDP group was significantly increased (5.7 vs. 1.9%, p < 0.05). CONCLUSIONS HDP increased the risk of PVL in EP/ELBW infants, but had no significant effect on the survival rate at discharge, or the occurrence of other complications.

Abstract
The improvement of delivery room care, according to the 2015 International Consensus, may affect neonatal outcome, especially in very-low-birth-weight infants. We aimed to investigate the current practice of neonatal resuscitation by year and analyze the association with neonatal outcomes. A total of 8142 very-low-birth-weight infants, registered in the Korean Neonatal Network between 2014 and 2017 were included. A significant decreasing trend of intubation (64.5% vs 55.1%, P < 0.0001) and markedly increasing trend of positive pressure ventilation (PPV) (11.5% vs 22.9%, P < 0.0001) were noted. The annual PPV rate differed significantly by gestation (P < 0.0001). The highest level of resuscitation was also shown as an independent risk factor for mortality within 7 days and for bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), and periventricular leukomalacia. PPV and intubation were associated with significantly decreased risk of mortality and morbidities compared to epinephrine use. When considering association, the incidence of mortality within 7 days, IVH, PVL, and BPD or mortality showed significant differences by combination of year, gestational age, and level of resuscitation. According to updated guidelines, changes in the highest level of resuscitation significantly associated with reducing mortality and morbidities. More meticulous delivery room resuscitation focusing on extreme prematurity is needed.

Abstract
OBJECTIVE Antenatal steroids improve the neonatal outcome if they are administered within a therapeutic window of seven days before preterm birth. The aim of this study was to evaluate the timing of antenatal steroids for imminent preterm birth at a single center in Germany. MATERIAL AND METHODS A 10-year retrospective analysis of 843 preterm births between 24/0 and 33/6 weeks was performed from January 2008 to December 2017 at a German university hospital. We evaluated the timing of antenatal steroids according to the indication for their application. Descriptive statistics and binomial regression were performed to analyze factors influencing the timing of antenatal steroid administration. RESULTS Of 843 preterm births below 34 weeks included in our study, 752 pregnant women received antenatal steroids (89.2%). Only 301/843 women (35.7%) gave birth within the optimal window of 7 days after antenatal steroids. 91/843 women (10.8%) did not receive steroids. 130/843 women (15.4%) only received one dose, 76/843 (9.0%) gave birth within 8 to 14 days, and 245/843 (29.1%) more than 14 days later. In a binomial regression model, preterm premature rupture of membranes (OR 3.40, 95% CI 1.81 to 6.39, p<0.001), fetal growth restriction (OR 3.27, 95% CI 1.63 to 6.58, p=0.001), and preeclampsia (OR 2.83, 95% CI 1.37 to 5.83, p=0.005) were positively associated with optimal timing. CONCLUSION Two thirds of women with preterm birth before 34 weeks received antenatal steroids outside the optimal therapeutic window. Further research is needed to achieve an optimal effect of antenatal steroids on neonatal outcome and to reduce untimely as well as unnecessary interventions.

Abstract
Background: Very preterm birth often results in the development of bronchopulmonary dysplasia (BPD) with an inverse correlation of gestational age and birthweight. This very preterm population is especially exposed to interventions, which affect the development of BPD. Objective: The goal of our review is to summarize the evidence on these daily procedures and provide evidence-based recommendations for the management of BPD. Methods: We conducted a systematic literature research using MEDLINE/PubMed on antenatal corticosteroids, surfactant-replacement therapy, caffeine, ventilation strategies, postnatal corticosteroids, inhaled nitric oxide, inhaled bronchodilators, macrolides, patent ductus arteriosus, fluid management, vitamin A, treatment of pulmonary hypertension and stem cell therapy. Results: Evidence provided by meta-analyses, systematic reviews, randomized controlled trials (RCTs) and large observational studies are summarized as a narrative review. Discussion: There is strong evidence for the use of antenatal corticosteroids, surfactant-replacement therapy, especially in combination with noninvasive ventilation strategies, caffeine and lung-protective ventilation strategies. A more differentiated approach has to be applied to corticosteroid treatment, the management of patent ductus arteriosus (PDA), fluid-intake and vitamin A supplementation, as well as the treatment of BPD-associated pulmonary hypertension. There is no evidence for the routine use of inhaled bronchodilators and prophylactic inhaled nitric oxide. Stem cell therapy is promising, but should be used in RCTs only.

Abstract
Placenta accreta spectrum (PAS) is an umbrella term for a variety of pregnancy complications due to abnormal placental implantation, including placenta accreta, placenta increta and placenta percreta. During the past several decades, the prevalence of PAS has been increasing, and the clinical importance of this disease is significant because of the severe complications. In this review, we summarized the available evidence-based data for PAS in various aspects: prevalence, risk factors, pathogenesis, clinical presentation and prenatal screening, and clinical management. Meanwhile, we provided a series of prospects in each section for further studies on PAS. Moreover, we first present a visualized workflow for the management of PAS from three steps: predelivery, during delivery and postdelivery.

Am J Obstet Gynecol 2021; 224:158-174. [PMID: 32745459 DOI: 10.1016/j.ajog.2020.07.051] [Citation(s) in RCA: 43] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 07/27/2020] [Accepted: 07/29/2020] [Indexed: 12/27/2022]
Abstract
OBJECTIVE The objective of this study was to provide a systematic review and meta-analysis to quantify prognosis and identify factors associated with variations in reported mortality estimates among infants who were born at 22 weeks of gestation and provided proactive treatment (resuscitation and intensive care). DATA SOURCES PubMed, Scopus, and Web of Science databases, with no language restrictions, were searched for articles published from January 2000 to February 2020. STUDY ELIGIBILITY CRITERIA Reports on live-born infants who were delivered at 22 weeks of gestation and provided proactive care were included. The primary outcome was survival to hospital discharge; secondary outcomes included survival without major morbidity and survival without neurodevelopmental impairment. Because we expected differences across studies in the definitions for various morbidities, multiple definitions for composite outcomes of major morbidities were prespecified. Neurodevelopmental impairment was based on Bayley Scales of Infant Development II or III. Data extractions were performed independently, and outcomes agreed on a priori. STUDY APPRAISAL AND SYNTHESIS METHODS Methodological quality was assessed using the Quality in Prognostic Studies tool. An adapted version of the Grading of Recommendations Assessment, Development and Evaluation approach for prognostic studies was used to evaluate confidence in overall estimates. Outcomes were assessed as prevalence and 95% confidence intervals. Variabilities across studies attributable to heterogeneity were estimated with the I2 statistic; publication bias was assessed with the Luis Furuya-Kanamori index. Data were pooled using the inverse variance heterogeneity model. RESULTS Literature searches returned 21,952 articles, with 2034 considered in full; 31 studies of 2226 infants who were delivered at 22 weeks of gestation and provided proactive neonatal treatment were included. No articles were excluded for study design or risk of bias. The pooled prevalence of survival was 29.0% (95% confidence interval, 17.2-41.6; 31 studies, 2226 infants; I2=79.4%; Luis Furuya-Kanamori index=0.04). Survival among infants born to mothers receiving antenatal corticosteroids was twice the survival of infants born to mothers not receiving antenatal corticosteroids (39.0% vs 19.5%; P<.01). The overall prevalence of survival without major morbidity, using a definition that includes any bronchopulmonary dysplasia, was 11.0% (95% confidence interval, 8.0-14.3; 10 studies, 374 infants; I2=0%; Luis Furuya-Kanamori index=3.02). The overall rate of survival without moderate or severe impairment was 37.0% (95% confidence interval, 14.6-61.5; 5 studies, 39 infants; I2=45%; Luis Furuya-Kanamori index=-0.15). Based on the year of publication, survival rates increased between 2000 and 2020 (slope of the regression line=0.09; standard error=0.03; P<.01). Studies were highly diverse with regard to interventions and outcomes reported. CONCLUSION The reported survival rates varied greatly among studies and were likely influenced by combining observational data from disparate sources, lack of individual patient-level data, and bias in the component studies from which the data were drawn. Therefore, pooled results should be interpreted with caution. To answer fundamental questions beyond the breadth of available data, multicenter, multidisciplinary collaborations, including alignment of important outcomes by stakeholders, are needed.

Abstract
OBJECTIVE To test the primary hypothesis that extremely preterm children antenatally exposed to both magnesium sulfate and antenatal corticosteroids have a lower rate of severe neurodevelopmental impairment or death compared with those exposed to antenatal corticosteroids alone. METHODS This was a prospective observational study of children born at 22 0/7-26 6/7 weeks of gestation from 2011 to 2014 at Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network hospitals (N=3,093). The primary outcome was severe neurodevelopmental impairment or death at 18-26 months of corrected age follow-up based on exposure to antenatal corticosteroids and magnesium sulfate or antenatal corticosteroids alone. Secondary outcomes included components of severe neurodevelopmental impairment by exposure group and comparisons of severe neurodevelopmental impairment or death between children exposed to both antenatal corticosteroids and magnesium sulfate with those exposed to magnesium sulfate alone or to neither antenatal corticosteroids nor magnesium sulfate. Logistic regression models adjusted for background characteristics. RESULTS Children exposed to both antenatal corticosteroids and magnesium sulfate had a lower rate of severe neurodevelopmental impairment or death (813/2,239, 36.3%) compared with those exposed to antenatal corticosteroids alone (225/508, 44.3%; adjusted odds ratio [aOR] 0.73; 95% CI 0.58-0.91), magnesium sulfate alone (47/89, 53%; aOR 0.49; 95% CI 0.29-0.82), or neither therapy (121/251; 48.2%; aOR 0.66, 95% CI 0.49-0.89). Similarly, children exposed to both antenatal corticosteroids and magnesium sulfate had a lower rate of death compared with either or neither therapy, but the rate of severe neurodevelopmental impairment among survivors did not differ between exposure groups. CONCLUSION In children born between 22 0/7 and 26 6/7 weeks of gestation, exposure to both antenatal corticosteroids and magnesium sulfate was associated with lower rates of severe neurodevelopmental impairment or death and death compared with exposure to antenatal corticosteroids alone.

Abstract
OBJECTIVE To evaluate the changes in the associations of antenatal corticosteroids (ACS) with neonatal mortality and severe neurological injury over time (2003-17). DESIGN National, population-representative, retrospective cohort study. SETTING Level III neonatal intensive care units participating in the Canadian Neonatal Network. POPULATION All infants born at 230/7 -336/7 weeks of gestation (n = 43 456). METHODS We estimated the associations between exposure to ACS and neonatal outcomes by year of birth. Year of birth was considered both continuously and categorically as three consecutive epochs. MAIN OUTCOME MEASURE Neonatal mortality and severe neurological injury. RESULTS The absolute rates of neonatal mortality and severe neurological injury decreased during the study period in both the ACS and No ACS groups. For infants born at 230/7 -306/7 weeks of gestation, ACS was associated with similar reductions in neonatal mortality across the three epochs (9.0% versus 18.1%, adjusted relative risk [aRR] 0.54, 95% CI 0.47-0.61 in 2003-09; 7.6% versus 19.6%, aRR 0.51, 95% CI 0.44-0.59 in 2010-13; and 7.3% versus 14.5%, aRR 0.56, 95% CI 0.46-0.68 in 2014-17) and in severe neurological injury (13.2% versus 25.8%, aRR 0.57, 95% CI 0.50-0.64 in 2003-09; 7.4% versus 17.4%, aRR 0.53, 95% CI 0.43-0.66 in 2010-14; and 7.2% versus 14.8%, aRR 0.59, 95% CI 0.48-0.74 in 2014-17). CONCLUSION Despite the ongoing improvements in neonatal care of preterm infants, as reflected by the gradual decrease in the absolute rates of neonatal mortality and severe neurological injury, the association of ACS treatment with neonatal mortality and severe neurological injury among extremely preterm infants born at 23-30 weeks of gestation has remained stable throughout the study period of 15 years. TWEETABLE ABSTRACT Despite the gradual decrease in the rates of neonatal mortality and severe neurological injury, antenatal corticosteroids remain an important intervention in the current era of neonatal care.

Abstract
Periviable deliveries (less than 26 weeks) are a small percentage of deliveries but account for a disproportionately high number of long-term morbidities. Few studies describe interventions and outcomes for periviable preterm premature rupture of membranes (PPROM). The available reports may include only those neonates who received resuscitation, making interpretation and application difficult. Counseling should consider the impact of oligohydramnios on fetal lung development. This article discusses standard and experimental interventions that may offer neonatal benefit. Antenatal corticosteroids, antibiotics, and magnesium sulfate may improve outcomes but data to support an improvement in outcome are limited. Studies specifically evaluating these interventions are needed.

Abstract
Antenatal corticosteroid (ACS) administration has been known as one of the most effective treatment in perinatal medicine, but the beneficial effects of ACS may vary not only gestational age, but also the quality of perinatal and neonatal care of the institution. This nationwide cohort study of the Korean Neonatal Network (KNN) data was consisted of <1,500g infants born at 23–34 weeks at 67 KNN hospitals between 2013 and 2017. The 9,142 eligible infants were assigned into two groups–group 1 and 2 <50% and ≥50% mortality rate, respectively, for 23–24 weeks’ gestation–reflecting the quality of perinatal and neonatal care. Each group of infants were further stratified into 23–24, 25–26, 27–28, and 29–34 weeks of gestation age. Despite comparable ACS usage between group 1 (82%) and group 2 (81%), the benefits of ACS were only observed in group 1. In the multivariable analyses, infants of group 1 showed significant decrease in mortality and IVH at gestational age 23–24 weeks with ACS use, and the decrease was also seen in early-onset sepsis and respiratory distress syndrome at gestational age of 29–34 weeks while there were no significant decrease in group 2. In this study the overall data was congruent with the previous findings stating that ACS use decreases mortality and morbidity. These results indicate that the improved mortality of infants at 23–24 weeks’ gestation reflects the quality improvement of perinatal and neonatal intensive care, which is a prerequisite to the benefits of ACS.

Abstract
Preterm birth is a vital global health-economic problem. Health disorders provoked by it generate a high neonatal mortality rate. Prenatal corticosteroid prevention aims to reduce postnatal complications in premature infants. This survey covered two basic baby groups: work group of 89 premature infants that had been subjected to prenatal corticosteroid prophylaxis and a control group of 78 premature babies without prenatal prevention. The analysis of the pharmacoeconomic aspects of prenatal corticosteroid prevention enabled the comparison of clinical and therapeutic results, treatment costs, therapeutic expenditures, shortterm therapeutic effect, benefits and sequences from premature infants’ therapy. The analysis of clinical data obtained during this survey enabled the conclusion that when analyzing the combined effect of Dexamethasone prophylaxis, gestation week at birth and the age of the mother of premature infants with RDS, respiratory obstuction occurrence was mediated by the earlier gestation week at birth, older mother’s age and, at this background, it was restricted to a certain extent by prenatal corticosteroid administration. Conclusions: Prenatal corticosteroids cause reduction of premature infants’ treatment costs. The implementation of a smaller number of dexamethasone applications leads to smaller expenditures for premature infants’ treatment and care compared to those that have more dexamethasone applications.

Abstract
OBJECTIVE To evaluate the most commonly used medications and in-hospital morbidities and mortality in infants born 22-24 weeks of gestation. STUDY DESIGN Multicenter retrospective cohort study of infants born 22-24 weeks of gestation (2006-2016), without major congenital anomalies and with available medication data obtained from neonatal intensive care units managed by the Pediatrix Medical Group. RESULTS This study included 7578 infants from 195 sites. Median (25th, 75th percentile): birthweight was 610 g (540, 680); the number of distinct medications used was 13 (8, 18); and different antimicrobial exposure was 4 (2, 5). The most common morbidities were BPD (41%) and grade III or IV IVH (20%), and overall survival varied from 46% (2006) to 57% (2016). CONCLUSIONS A large number of medications were used in periviable infants. There was a high prevalence of in-hospital morbidities, and survival of this population increased over the study period.

Abstract
Antenatal corticosteroids are now established as one of the cornerstones of therapy in the prevention of neonatal morbidity and mortality prior to preterm birth. Although this practice is widely accepted, a significant number of controversies exist. This review explores the knowledge gaps regarding the use of antenatal corticosteroids in the preterm, late preterm and term populations. Furthermore, the role of antenatal corticosteroids in special populations, such as diabetes, multiple pregnancies and periviable gestations, where high-quality data from randomized controlled trials are lacking, is also considered.

Intention to treat: obstetrical management at the threshold of viability. Am J Obstet Gynecol MFM 2020; 2:100096. [PMID: 33345962 DOI: 10.1016/j.ajogmf.2020.100096] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 02/17/2020] [Accepted: 02/18/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Despite medical advances in the care of extremely preterm neonates and growing acceptance of resuscitation at 23 and even 22 weeks gestation, controversy remains concerning the use of antepartum obstetric intervention s that are intended to improve outcomes in the setting of anticipated extremely preterm birth. In the absence of demonstrated benefit at <23 weeks gestation and with uncertain benefit at 23 weeks gestation, previous obstetric committee opinions have advised against their use at these gestational ages. OBJECTIVE The purpose of this study was to review the use of obstetric intervention s at the threshold of viability based on neonatal resuscitation plan and to review the odds of survival to neonatal intensive care unit discharge based on use of obstetric intervention s with adjustment for neonatal factors. STUDY DESIGN This retrospective study of 6 study centers reviewed pregnant patients who were admitted between 22+0/7 and 24+6/7 weeks gestation facing delivery from 2011-2015. Patients with known anomalies or missing data were excluded. Records were reviewed for demographics, resuscitation plan, and obstetric intervention s. Mode of delivery, delivery room care, and final infant dispositions were recorded. Multiple gestations were included as 1 pregnancy in regard to the use of obstetric intervention s and were excluded from survival analysis. RESULTS Four hundred seventy-eight mothers met the inclusion criteria. When resuscitation was planned, mothers were more likely to receive all conventional obstetric intervention s (antenatal steroids, magnesium sulfate for neuroprotection, tocolytics, and Group Beta Streptococcus prophylaxis), regardless of gestational age at admission, and were more likely to be delivered by cesarean section (P<.05). Analyzed as a group, when antenatal steroids, magnesium sulfate, tocolytics and Group Beta Streptococcus prophylaxis were administered, the odds of survival to neonatal intensive care unit discharge increased for newborn infants who were born at 22 (odds ratio, 11.33; 95% confidence interval, 1.405-91.4) and 23 weeks gestation (odds ratio, 15.5; 95% confidence interval, 3.747-64.11; P<.05). In singletons, the odds of survival to neonatal intensive care unit discharge was not improved by cesarean delivery vs vaginal delivery, even after adjustment for the use of additional interventions, weight, gender, and gestational age (odds ratio, 1.0; 95% confidence interval, 0.59-1.8; P=.912). CONCLUSION In this study, when postnatal resuscitation was planned at 22 and 23 weeks gestation, women were more likely to receive antenatal steroids, magnesium sulfate, and antibiotics; provision of this bundle imparted survival benefit at 23 weeks gestation but could not be demonstrated at 22 weeks gestation because of the small sample size. These findings support of neonate-oriented obstetric interventions in the setting of delivery at 23 weeks gestation when resuscitation is planned and further exploration of optimal obstetric care when resuscitation of infants who were born at 22 weeks gestation is anticipated.

Abstract
OBJECTIVES To determine the incidence, trends, maternal and neonatal risk factors of severe intraventricular hemorrhage (IVH) among infants born 24-32 weeks and/or < 1500 g, and to evaluate the impact of changing of hospital policies and unit clinical practice on the IVH incidence. STUDY DESIGN Retrospective chart review of preterm infants with a gestational age (GA) of 24-326 weeks and/or weight of < 1500 g born at King Abdulaziz Medical City-Riyadh (KAMC-R), Saudi Arabia, from 2016 to 2018. Multivariate logistic regression model was constructed to determine the probability of developing severe IVH and identify associations with maternal and neonatal risk factors. RESULTS Among 640 infants, the overall incidence of severe IVH was 6.4% (41 infants), and its rate decreased significantly, from 9.4% in 2016 to 4.5% and 5% in 2017 and 2018 (p = 0.044). Multivariate analysis revealed that caesarian section delivery decreased the risk of severe IVH in GA group 24-27 weeks (p = 0.045). Furthermore use of inotropes (p = 0.0004) and surfactant (p = 0.0003) increased the risk of severe IVH. Despite increasing use of inotropes (p = 0.024), surfactant therapy (p = 0.034), and need for delivery room intubation (p = 0.015), there was a significant reduction in the incidence of severe IVH following the change in unit clinical practice and hospital policy (p = 0.007). CONCLUSION Cesarean section was associated with decreased all grades of IVH and severe IVH, while use of inotropes was associated with increased severe IVH. The changes in hospital and unit policy were correlated with decreased IVH during the study period.

Abstract
This retrospective cohort study aimed to investigate the prevalence, morbidity, mortality and the maternal/neonatal care of preterm neonates and the perinatal risk factors for mortality. We included data on 13,701 preterm neonates born in 15 hospitals for the period 2013–2014 in China. Results showed a prevalence of preterm neonates of 9.9%. Most infants at 24–27 weeks who survived more than 12 hours were mechanically ventilated (56.1%). Few infants born before 28 weeks received CPAP without first receiving mechanical ventilation (8.1%). Few preterm neonates received antenatal steroid(35.8% at 24–27 weeks, 57.9% at 28–31 weeks, 57.0% at 32–33 weeks and 32.7% at 34–36 weeks). Overall mortality was 1.9%. Most of the deaths at 24–27 weeks of gestation occurred within 12 hours after birth, accounting for 68.1%(32/47), and within 12–72 hours after birth at 28–36 weeks of gestation, accounting for 47.4%(99/209). Rates of survival to discharge increased from 68.2% at 24–27 weeks, 93.3% at 28–31 weeks, 99.2% at 32–33 weeks to 99.4% at 34–36 weeks. The smaller of the GA, there was a greater risk of morbidities due to prematurity. Preterm birth weight (OR = 0.407, 95% CI 0.346–0.478), antenatal steroid (OR = 0.680, 95% CI 0.493–0.938), and neonatal asphyxia (OR = 3.215, 95% CI 2.180–4.741) proved to significantly influence the odds of preterm neonatal death. Overall, our results support that most of the preterm neonates at 28–36 weeks of gestation survived without major morbidity. Rate of survival of GAs less than 28 weeks was still low. Maternal and infant care practices need to be improved in the very preterm births.

Abstract
BACKGROUND/PURPOSE The aim of this study was to evaluate the efficacy of antenatal corticosteroids for preventing very low birth weight (VLBW) infants with respiratory distress syndrome (RDS) from surfactant use at different gestational ages (GA). METHODS We retrospectively analyzed the VLBW preterm infants registered in the Premature Baby Foundation of Taiwan from 1997 through 2014. Infants at 20-37 weeks' gestation were included, and infants with lethal congenital anomaly, chromosomal anomaly, and congenital infection were excluded. Antenatal corticosteroid courses were classified into two groups (<2 doses or ≧2 doses). The beneficial effect of antenatal corticosteroids on preventing VLBW infants with RDS from surfactant use was evaluated according to gestational ages. RESULTS Total 12,685 VLBW infants were included. For VLBW infants with gestational age 26-33 weeks, antenatal corticosteroid therapy has significantly protective effect (odds ratio 0.43 [95% CI 0.26 to 0.72] - 0.60 [95% CI 0.48 to 0.75], P < 0.05). The effect was not obvious for VLBW infants with gestational age 34 weeks and more (odds ratio 0.32 [95% CI 0.08 to 1.38], P = 0.127). CONCLUSION For VLBW infants with RDS at 34 weeks' gestation and more, the beneficial effect of antenatal corticosteroids on preventing surfactant use was not evident. In conclusion, completion of two doses or more of antenatal corticosteroids is of great importance for VLBW infants with RDS at gestational age between 26 and 33 weeks on preventing surfactant use.

Abstract
AIM The presence of amniotic fluid sludge has been identified as a risk factor for preterm birth. We sought to validate the clinical characteristics of amniotic fluid sludge in Japanese pregnant women with preterm labor and intact membranes. METHODS This was a retrospective study of 54 patients. The presence of amniotic fluid sludge was confirmed using transvaginal ultrasonography data during pregnancy. The following data were collected: gestational age, the presence of histologic chorioamnionitis, time from the diagnosis of threatened premature labor to delivery, oncofetal fibronectin (onfFN) levels, C-reactive protein peak value levels, cervical length at the time of onset of threatened premature labor and types of neonatal complications. RESULTS Significant differences (P = 0.03) were observed in the age at delivery in relation to the presence of amniotic sludge: delivery occurred at 28.3 ± 4.5 weeks and 31.7 ± 4.3 weeks in sludge positive patients and sludge-negative patients, respectively. Presence of sludge in patients diagnosed with histological chorioamnionitis at <37 weeks of gestation differed significantly (P = 0.01): sludge-positive, 81.8%; sludge-negative, 20.9%. Among the sludge-positive patients, 100% were positive for serum onfFN (≥50 ng/mL), whereas only 54% of sludge-negative patients were positive for serum onfFN (P = 0.03). Presence of amniotic fluid sludge did not significantly affect neonatal complications. CONCLUSION Our results confirmed previous findings that amniotic fluid sludge is a self-determining risk factor for preterm birth and chorioamnionitis in pregnant Japanese women.

Abstract
OBJECTIVE We sought to develop and validate a novel scoring system for the prediction of severe intraventricular hemorrhage (SIVH) in very low birth weight infants (VLBWI). METHODS This retrospective cohort multicenter study included 615 VLBWI born between 24 and 32 weeks gestational age (GA). Multivariable logistic regression analyses were used to determine which factors evaluated within the first 5 days of life were associated with SIVH and the weights of these variables. The accuracy of the predictive scoring system was prospectively tested in the same units. RESULTS The final SIVH scoring system included the following variables: antenatal steroid therapy, GA, birth weight (BW), 1-min Apgar score, mechanical ventilation and hypotension. The SIVH scores used to divide the subjects into three tiers (low-risk (<5), moderate-risk (5-8) and high-risk (>8)) were developed based on these variables. Of infants with a score below 5, 1.2% (4/339) developed SIVH. Of those with a score above 8, 42.5% (17/40) developed SIVH. The scores were successfully verified in 99 VLBWI. CONCLUSIONS These findings suggest that among infants with a score >8, the incidence of SIVH is significantly higher. This scoring system can be used to predict the incidence of SIVH during the first 5 days after birth and may contribute to the early intervention in and prevention of SIVH.

Abstract
OBJECTIVE The primary objective of this guideline was to develop consensus statements to guide clinical practice and recommendations for obstetric management of a pregnancy at borderline viability, currently defined as prior to 25+6 weeks. INTENDED USERS Clinicians involved in the obstetric management of women whose fetus is at the borderline of viability. TARGET POPULATION Women presenting for possible birth at borderline viability. EVIDENCE This document presents a summary of the literature and a general consensus on the management of pregnancies at borderline viability, including maternal transfer and consultation, administration of antenatal corticosteroids and magnesium sulfate, fetal heart rate monitoring, and considerations in mode of delivery. Medline, EMBASE, and Cochrane databases were searched using the following keywords: extreme prematurity, borderline viability, preterm, pregnancy, antenatal corticosteroids, mode of delivery. The results were then studied, and relevant articles were reviewed. The references of the reviewed studies were also searched, as were documents citing pertinent studies. The evidence was then presented at a consensus meeting, and statements were developed. VALIDATION METHODS The content and recommendations were developed by the consensus group from the fields of Maternal-Fetal Medicine, Neonatology, Perinatal Nursing, Patient Advocacy, and Ethics. The quality of evidence was rated using criteria described in the Grading of Recommendations Assessment, Development and Evaluation methodology framework (reference 1). The Board of the Society of Obstetricians and Gynaecologists of Canada approved the final draft for publication. METHODS The quality of evidence was rated using the criteria described in the Grading of Recommendations, Assessment, Development, and Evaluation methodology framework. The interpretation of strong and weak recommendations is described later. The Summary of Findings is available upon request. BENEFITS, HARMS, AND COSTS A multidisciplinary approach should be used in counselling women and families at borderline viability. The impact of obstetric interventions in the improvement of neonatal outcomes is suggested in the literature, and if active resuscitation is intended, then active obstetric interventions should be considered. GUIDELINE UPDATE Evidence will be reviewed 5 years after publication to decide whether all or part of the guideline should be updated. However, if important new evidence is published prior to the 5-year cycle, the review process may be accelerated for a more rapid update of some recommendations. SPONSORS This guideline was developed with resources funded by the Society of Obstetricians and Gynaecologists of Canada and the Women and Babies Program at Sunnybrook Health Sciences Centre.

Abstract
BACKGROUND This study was performed to determine survival and morbidity rates in very low birth weight infants (VLBWIs) in the Korean Neonatal Network (KNN), and to compare neonatal outcomes with those in other countries. METHODS Data were collected for 8,269 VLBWIs with gestational age (GA) ≥ 22 weeks who were born between January 1, 2013 and December 31, 2016, and admitted to the neonatal intensive care units of the KNN. RESULTS The survival rate of all VLBWIs and of infants with GA 22-23, 24-25, 26-27, 28-29, 30-32, and > 32 weeks were 86% (total), 33%, 65%, 84%, 94%, 97%, and 98%, respectively. The bronchopulmonary dysplasia (BPD) rates of all VLBWIs and of infants with GA 22-23, 24-25, 26-27, 28-29, 30-32, and > 32 weeks were 30% (total), 88%, 64%, 47%, 26%, 14%, and 5%, respectively. The intraventricular hemorrhage rates (≥ grade III) of all VLBWIs and of infants with GA 22-23, 24-25, 26-27, 28-29, 30-32, and > 32 weeks were 10% (total), 45%, 27%, 12%, 5%, 2%, and 1%, respectively. In an international comparison, the survival rate of VLBWIs with GA 24-27 weeks in KNN was lower, and the BPD rate of VLBWIs in the KNN was higher than that of the neonatal networks of other countries. CONCLUSION Despite overall improvements in neonatal outcomes, the survival and morbidity rates of more immature infants with GA 22-27 weeks need further improvement. Therefore, it would be necessary to develop more optimal treatment strategies and perform more active quality improvement to further improve neonatal outcomes of VLBWIs in Korea.

Abstract
IMPORTANCE Although evidence of antenatal steroids (ANS) efficacy at 22 to 25 weeks' gestation is limited, increasingly these infants are treated with postnatal life support. OBJECTIVES To estimate the proportion of infants receiving postnatal life support at 22 to 25 weeks' gestation who had exposure to ANS, and to examine if the provision of ANS was associated with a higher rate of survival to hospital discharge and survival without major morbidities. DESIGN, SETTING, AND PARTICIPANTS This multicenter observational cohort study consisted of 33 472 eligible infants liveborn at 431 US Vermont Oxford Network member hospitals between January 1, 2012, and December 31, 2016. We excluded infants with recognized syndromes or major congenital anomalies. Of the eligible infants, 29 932 received postnatal life support and were included in the analyses. Data analysis was conducted from July 2017 to July 2018. EXPOSURE Antenatal steroids administered to the mother at any time prior to delivery. MAIN OUTCOMES AND MEASURES Survival to hospital discharge, major morbidities among survivors, and the composite of survival to discharge without major morbidities. RESULTS Among 29 932 infants who received postnatal life support, 51.9% were male, with a mean (SD) gestational age of 24.12 (0.86) weeks and mean (SD) birth weight of 668 (140) g; 26 090 (87.2%) had ANS exposure and 3842 (12.8%) had no ANS exposure. Survival to hospital discharge was higher for infants with ANS exposure (18 717 of 25 892 [72.3%]) compared with infants without ANS exposure (1981 of 3820 [51.9%]); the adjusted risk ratio for 22 weeks was 2.11 (95% CI, 1.68-2.65), for 23 weeks was 1.54 (95% CI, 1.40-1.70), for 24 weeks was 1.18 (95% CI, 1.12-1.25), and for 25 weeks was 1.11 (95% CI, 1.07-1.14). Survival to hospital discharge without major morbidities was higher for infants with ANS exposure (3777 of 25 833 [14.6%]) compared with infants without ANS exposure (347 of 3806 [9.1%]); the adjusted risk ratio for 22 through 25 weeks was 1.67 (95% CI, 1.49-1.87). CONCLUSIONS AND RELEVANCE Concordant receipt of ANS and postnatal life support was associated with significantly higher survival and survival without major morbidities at 22 through 25 weeks' gestation compared with life support alone. Although statistically higher with ANS, survival without major morbidities remains low at 22 and 23 weeks. There is an opportunity to reevaluate national obstetric guidelines, allowing for shared decision making at the edge of viability with concordant obstetrical and neonatal treatment plans.

Abstract
OBJECTIVE To determine the association between antenatal corticosteroid treatment and neonatal complications in diabetic mothers delivering after 34 weeks of gestation. METHODS A retrospective cohort study of women with singleton pregnancies diagnosed with gestational diabetes who delivered after 34 weeks of gestation in a university-affiliated medical center (2012-2016). Mothers treated with corticosteroids prior to 34 + 0 weeks of gestation were divided according to gestational age at delivery: late-preterm (34 + 0 to 36 + 6) and term (37 + 0 to 41 + 6). Each group was compared to women delivering at the same gestational age who were not treated with corticosteroids. Primary outcome was defined as a neonatal adverse composite outcome. Birth weight was amongst secondary outcomes measured. Logistic regression analysis was utilized to adjust results to potential confounders. RESULTS During the study period, 161 diabetic mothers delivered at late-preterm. Amongst them, 47 (30%) were treated with corticosteroids. 2101 diabetic mothers delivered at term, amongst them 82 (4%) were treated with corticosteroids. Primary outcome did not differ between groups. Multivariate analysis demonstrated that corticosteroid treatment was not associated with neonatal adverse composite outcome when delivery occurred at the late preterm, nor at term (adjusted odds ratio (aOR) = 0.708, 95% CI 0.2-2.3, p = 0.572, and aOR = 1.6, 95% CI 0.2-12.7, p = 0.635, respectively). Birth weight was significantly lower in women treated with corticosteroids (2486 vs. 2675 g, p = 0.02 at late-preterm, and 3160 vs. 3319 g, p < 0.001 at term). CONCLUSION Corticosteroid treatment for diabetic mothers was not associated with neonatal adverse outcomes, but was found associated with a lower birth weight, when delivery occurs after 34 weeks of gestation.

Trends in the neurodevelopmental outcomes among preterm infants from 2003-2012: a retrospective cohort study in Japan. J Perinatol 2018; 38:917-928. [PMID: 29679045 DOI: 10.1038/s41372-018-0061-7] [Citation(s) in RCA: 39] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2017] [Revised: 12/10/2017] [Accepted: 01/22/2018] [Indexed: 12/16/2022]
Abstract
OBJECTIVES To determine the trends in mortality and the prevalence of abnormal neurodevelopmental outcomes among preterm Japanese infants. STUDY DESIGN A retrospective multicenter cohort of 30,793 preterm infants born at a gestational age ≤32 weeks, between 2003 and 2012, in the Neonatal Research Network, Japan, was evaluated in the primary analysis. Finally, 13,661 infants were followed-up until 3 years of age and evaluated for neurodevelopmental outcomes, including cerebral palsy (CP), home oxygen therapy (HOT) use, and visual, hearing, and cognitive impairments. Multivariable logistic regression analysis was performed to determine the risk-adjusted trends in mortality and long-term neurodevelopmental outcomes. RESULTS The trends in overall mortality (adjusted odds ratio, (AOR): 0.92; 95% confidence interval, (CI): 0.89-0.94), the prevalence of CP (AOR: 0.95, 95% CI: 0.92-0.98), HOT use (AOR: 0.84, 95% CI: 0.75-0.93), and visual (AOR: 0.84, 95% CI: 0.81-0.87) and hearing impairments (AOR: 0.78, 95% CI: 0.63-0.97) showed a significant downward trend, while cognitive impairment showed no significant changes (AOR: 1.02, 95% CI: 0.99-1.05). Intravenous hyperalimentation was significantly correlated with visual impairment (AOR 0.74, 95% CI 0.59-0.91). Early establishment of enteral feeding was associated with improved long-term outcomes. CONCLUSIONS Mortality was improved, and this did not lead to increased risks for abnormal neurodevelopmental outcomes. Nutritional support might improve long-term neurodevelopmental outcomes.

Abstract
AIM To assess the effects of differential exposure to antenatal corticosteroid (ACS) on short- and long-term outcomes of infants born before 24 weeks of gestation. METHODS This is a retrospective cohort study of 147 infants delivered by 116 women at 21-23 weeks of gestation between January 2001 and December 2016 at a tertiary referral hospital in Seoul, Korea. Eligible subjects were categorized into the following three groups according to ACS exposure: non-user (n = 53), partial-course (n = 44), and complete-course (n = 50). Univariable and multivariable analyses were used to compare neonatal mortality, neonatal morbidities including intraventricular hemorrhage (IVH), and neurodevelopmental impairment including cerebral palsy among the three groups. RESULTS Neonatal mortality rate was significantly lower in the ACS-user groups (non-user, 52.8%; partial-course, 27.3%; complete-course, 28.0%; P = 0.01), but complete-course of ACS therapy had no advantages over partial-course. A lower incidence of IVH was observed in the complete-course group (non-users, 54.8%; partial-course, 48.6%; complete-course, 20.5%; P = 0.003). Multiple logistic regression analysis showed that ACS therapy, either partial- or complete-course, was associated with a lower rate of neonatal mortality (adjusted odds ratio (aOR) 0.375; 95% confidence interval (CI) 0.141-0.996 in partial-course; aOR 0.173; 95% CI 0.052-0.574) in complete-course). IVH (aOR 0.191; 95% CI 0.071-0.516) was less likely to occur in the complete-course group than in the non-user group. Neurodevelopmental impairment of survivors at 18-22 month after birth was not significantly different among the three groups. CONCLUSION ACS therapy in preterm births at 21-23 weeks of gestation was associated with significantly reduced rates of neonatal mortality and IVH, especially with complete administration.

Increased H3K27ac level of ACE mediates the intergenerational effect of low peak bone mass induced by prenatal dexamethasone exposure in male offspring rats. Cell Death Dis 2018; 9:638. [PMID: 29844424 PMCID: PMC5974192 DOI: 10.1038/s41419-018-0701-z] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Revised: 05/03/2018] [Accepted: 05/07/2018] [Indexed: 12/21/2022]
Abstract
Prenatal dexamethasone exposure (PDE) induces developmental toxicities of multiple organs in offspring. Here, we verified the intergenerational effect of low peak bone mass induced by PDE and investigated its intrauterine programming mechanism. Pregnant rats were injected subcutaneously with 0.2 mg/kg/d dexamethasone from gestation day (GD) 9 to 20. Some pregnant rats were killed for the fetuses on GD20, and the rest went on to spontaneous labor to produce the first-generation (F1) offspring. The adult F1 male offspring were mated with normal females to produce the F2 offspring. In vivo, PDE leads to low peak bone mass in F1 male offspring rats at postnatal week (PW) 28. Furthermore, PDE reduced the bone mass in F1 male offspring from GD20 to PW12. Meanwhile, the osteogenic differentiation was suppressed and the local renin–angiotensin system (RAS) was activated continuously by PDE. Moreover, the histone 3 lysine 27 acetylation (H3K27ac) level in angiotensin-converting enzyme (ACE) promoter region was increased by PDE from GD20 to PW12. Likewise, PDE induced the low peak bone mass and the activated local RAS in F2 male offspring. Meaningfully, the H3K27ac level of ACE was increased by PDE in the F2 offspring. In vitro, dexamethasone inhibited bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation and promoted RAS activation. Furthermore, dexamethasone recruited CCAAT/enhancer-binding protein α and p300 into the BMSCs nucleus by activating glucocorticoid receptor, which cooperatively increased the H3K27ac level in the ACE promoter region. In conclusion, PDE induced the low peak bone mass and its intergenerational effect, which was mediated by sustained activation of RAS via increasing H3K27ac level of ACE.

Abstract
BACKGROUND The efficacy of antenatal steroids for fetal lung maturation in the periviable period is not fully understood. OBJECTIVE We sought to determine the lung maturational effects of antenatal steroids and inflammation in early gestation sheep fetuses, similar to the periviable period in human beings. STUDY DESIGN Date-mated ewes with singleton fetuses were randomly assigned to 1 of 4 treatment groups (n = 8/group): (1) maternal intramuscular injection of betamethasone; (2) intraamniotic lipopolysaccharide; (3) betamethasone + lipopolysaccharide; and (4) intraamniotic + intramuscular saline (controls). Fetuses were delivered surgically 48 hours later at 94 days' gestation (63% term gestation) for comprehensive evaluations of lung maturation, and lung and systemic inflammation. RESULTS Relative to controls, first, betamethasone increased the fetal lung air space to mesenchymal area ratio by 47% but did not increase the messenger RNAs for the surfactant proteins-B and -C that are important for surfactant function or increase the expression of pro-surfactant protein-C in the alveolar type II cells. Second, betamethasone increased expression of 1 of the 4 genes in surfactant lipid synthetic pathways. Third, betamethasone increased genes involved in epithelium sodium channel transport, but not sodium-potassium adenosine triphosphatase or Aquaporin 5. Fourth, lipopolysaccharide increased proinflammatory genes in the lung but did not effectively recruit activated inflammatory cells. Last, betamethasone incompletely suppressed lipopolysaccharide-induced lung inflammation. In the liver, betamethasone when given alone increased the expression of serum amyloid A3 and C-reactive protein messenger RNAs. CONCLUSION Compared the more mature 125-day gestation sheep, antenatal steroids do not induce pulmonary surfactants during the periviable period, indicating a different response.
