Glob Health Action 2024; 17:2392354. [PMID: 39210735 PMCID: PMC11370670 DOI: 10.1080/16549716.2024.2392354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 08/12/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND A neonatal mortality prediction score can assist clinicians in making timely clinical decisions to save neonates' lives by facilitating earlier admissions where needed. It can also help reduce unnecessary admissions. OBJECTIVE The study aimed to develop and validate a prognosis risk score for neonatal mortality within 28 days in public hospitals in the Amhara region, Ethiopia. METHODS The model was developed using a validated neonatal near miss assessment scale and a prospective cohort of 365 near-miss neonates in six hospitals between July 2021 and January 2022. The model's accuracy was assessed using the area under the receiver operating characteristics curve, calibration belt, and the optimism statistic. Internal validation was performed using a 500-repeat bootstrapping technique. Decision curve analysis was used to evaluate the model's clinical utility. RESULTS In total, 63 of the 365 neonates died, giving a neonatal mortality rate of 17.3% (95% CI: 13.7-21.5). Six potential predictors were identified and included in the model: anemia during pregnancy, pregnancy-induced hypertension, gestational age less than 37 weeks, birth asphyxia, 5 min Apgar score less than 7, and birth weight less than 2500 g. The model's AUC was 84.5% (95% CI: 78.8-90.2). The model's predictive ability while accounting for overfitting via internal validity was 82%. The decision curve analysis showed higher clinical utility performance. CONCLUSION The neonatal mortality predictive score could aid in early detection, clinical decision-making, and, most importantly, timely interventions for high-risk neonates, ultimately saving lives in Ethiopia.

Ethno-racial inequalities on adverse birth and neonatal outcomes: a nationwide, retrospective cohort study of 21 million Brazilian newborns. LANCET REGIONAL HEALTH. AMERICAS 2024; 37:100833.

Abstract
Background Ethno-racial inequalities are critical determinants of health outcomes. We quantified ethnic-racial inequalities on adverse birth outcomes and early neonatal mortality in Brazil. Methods We conducted a cohort study in Brazil using administrative linked data between 2012 and 2019. Estimated the attributable fractions for the entire population (PAF) and specific groups (AF), as the proportion of each adverse outcome that would have been avoided if all women had the same baseline conditions as White women, both unadjusted and adjusted for socioeconomics and maternal risk factors. AF was also calculated by comparing women from each maternal race/skin colour group in different groups of mothers' schooling, with White women with 8 or more years of education as the reference group and by year. Findings 21,261,936 newborns were studied. If all women experienced the same rate as White women, 1.7% of preterm births, 7.2% of low birth weight (LBW), 10.8% of small for gestational age (SGA) and 11.8% of early neonatal deaths would have been prevented. Percentages preventable were higher among Indigenous (22.2% of preterm births, 17.9% of LBW, 20.5% of SGA and 19.6% of early neonatal deaths) and Black women (6% of preterm births, 21.4% of LBW, 22.8% of SGA births and 20.1% of early neonatal deaths). AF was higher in groups with fewer years of education among Indigenous, Black and Parda for all outcomes. AF increased over time, especially among Indigenous populations. Interpretation A considerable portion of adverse birth outcomes and neonatal deaths could be avoided if ethnic-racial inequalities were non-existent in Brazil. Acting on the causes of these inequalities must be central in maternal and child health policies. Funding Bill & Melinda Gates Foundation and Wellcome Trust.

Am J Clin Nutr 2024; 120:111-120. [PMID: 38719093 DOI: 10.1016/j.ajcnut.2024.04.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 04/25/2024] [Accepted: 04/29/2024] [Indexed: 05/23/2024] Open
Abstract
BACKGROUND Infants born moderate-to-late preterm (i.e., 32 wk-35 wk 6 d gestation) are, analogous to those born very preterm, at risk of later obesity, hypertension, and diabetes. Appropriate early life nutrition is key for ensuring optimal growth and body composition, thereby mitigating potential cardiometabolic risks. OBJECTIVES We aimed to compare growth and body composition between infants born moderate-to-late preterm fed isocaloric but protein- and mineral-enriched postdischarge formula (PDF) or standard term formula (STF) until 6 mo corrected age (CA; i.e., after term equivalent age [TEA]). METHODS After enrollment (≤7 d postpartum), infants received PDF if (fortified) mother's own milk (MOM) was insufficient. At TEA, those receiving >25% of intake as formula were randomized to either continue the same PDF (n = 47) or switch to STF (n = 50); those receiving ≥75% of intake as MOM (n = 60) served as references. At TEA and 6 mo CA, we assessed anthropometry and body composition using both dual-energy x-ray absorptiometry (DXA) and air displacement plethysmography (ADP). RESULTS Feeding groups had similar gestational age (median [25th percentile;75th percentile]: 34.3 [33.5; 35.1] wk), birthweight (mean ± standard deviation [SD]: 2175 ± 412 g), anthropometry, and body composition at TEA. At 6 mo CA, infants fed PDF had slightly, but significantly, greater length (67.6 ± 2.5 and 66.9 ± 2.6 cm, P < 0.05) and larger head circumference (43.9 ± 1.3 and 43.4 ± 1.5 cm, P < 0.05) compared to infants fed STF. Also, infants fed PDF had higher lean mass (LM) and bone mineral content estimated by DXA (4772 ± 675 and 4502 ± 741 g; 140 ± 20 and 131 ± 23 g, respectively; P < 0.05). ADP estimates, however, were not statistically different between feeding groups. CONCLUSIONS Infants born moderate-to-late preterm demonstrated modest increases in length, head circumference, LM, and bone mineral content when fed PDF compared to STF for 6 mo after TEA. This trial was registered at the International Clinical Trial Registry Platform as NTR5117 and NTR NL4979.

Abstract
While its etiology is not fully elucidated, preterm birth represents a major public health concern as it is the leading cause of child mortality and morbidity. Stress is one of the most common perinatal conditions and may increase the risk of preterm birth. In this paper we aimed to investigate the association of maternal perceived stress and anxiety with length of gestation. We used harmonized data from five birth cohorts from Canada, France, and Norway. A total of 5297 pregnancies of singletons were included in the analysis of perceived stress and gestational duration, and 55,775 pregnancies for anxiety. Federated analyses were performed through the DataSHIELD platform using Cox regression models within intervals of gestational age. The models were fit for each cohort separately, and the cohort-specific results were combined using random effects study-level meta-analysis. Moderate and high levels of perceived stress during pregnancy were associated with a shorter length of gestation in the very/moderately preterm interval [moderate: hazard ratio (HR) 1.92 (95%CI 0.83, 4.48); high: 2.04 (95%CI 0.77, 5.37)], albeit not statistically significant. No association was found for the other intervals. Anxiety was associated with gestational duration in the very/moderately preterm interval [1.66 (95%CI 1.32, 2.08)], and in the early term interval [1.15 (95%CI 1.08, 1.23)]. Our findings suggest that perceived stress and anxiety are associated with an increased risk of earlier birth, but only in the earliest gestational ages. We also found an association in the early term period for anxiety, but the result was only driven by the largest cohort, which collected information the latest in pregnancy. This raised a potential issue of reverse causality as anxiety later in pregnancy could be due to concerns about early signs of a possible preterm birth.

Abstract
OBJECTIVE To describe the prevalence of and between-center variations in care practices and clinical outcomes of moderate and late preterm infants (MLPIs) admitted to tertiary Canadian neonatal intensive care units (NICUs). STUDY DESIGN This was a retrospective cohort study including infants born at 320/7 through 366/7 weeks of gestation and admitted to 25 NICUs participating in the Canadian Neonatal Network between 2015 and 2020. Patient characteristics, process measures represented by care practices, and outcome measures represented by clinical in-hospital and discharge outcomes were reported by gestational age weeks. NICUs were compared using indirect standardization after adjustment for patient characteristics. RESULTS Among 25 669 infants (17% of MLPIs born in Canada during the study period) included, 45% received deferred cord clamping, 7% had admission hypothermia, 47% received noninvasive respiratory support, 11% received mechanical ventilation, 8% received surfactant, 40% received antibiotics in the first 3 days, 4% did not receive feeding in the first 2 days, and 77% had vascular access. Mortality, early-onset sepsis, late-onset sepsis, or necrotizing enterocolitis occurred in <1% of the study cohort. Median (IQR) length of stay was 14 (9-21) days among infants discharged home from the admission hospital and 5 (3-9) days among infants transferred to community hospitals. Among infants discharged home, 33% were discharged on exclusive breastmilk and 75% on any breastmilk. There were significant variations between NICUs in all process and outcome measures. CONCLUSIONS Care practices and outcomes of MLPIs varied significantly between Canadian NICUs. Standardization of process and outcome quality measures for this population will enable benchmarking and research, facilitating systemwide improvements.

Abstract
OBJECTIVE To assess the relative risk of mortality in infants born preterm and small for gestational age (SGA) during the first and second months of life in rural Bangladesh. STUDY DESIGN We analyzed data from a cohort of pregnant women and their babies in Sylhet, Bangladesh, assembled between 2011 and 2014. Community health workers visited enrolled babies up to 10 times from birth to age 59 days. Survival status was recorded at each visit. Gestational age was estimated from mother's reported last menstrual period. Birth weights were measured within 72 hours of delivery. SGA was defined using the INTERGROWTH-21st standard. We estimated unadjusted and adjusted hazard ratios (HRs) and corresponding 95% CIs for babies born preterm and SGA separately for the first and second month of life using bivariate and multivariable weighted Cox regression models. RESULTS The analysis included 17 643 singleton live birth babies. Compared with infants born at term-appropriate for gestational age, in both unadjusted and adjusted analyses, infants born preterm-SGA had the greatest risk of death in the first (HR 13.25, 95% CI 8.65-20.31; adjusted HR 12.05, 95% CI 7.82-18.57) and second month of life (HR 4.65, 95% CI 1.93-11.23; adjusted HR 4.1, 95% CI 1.66-10.15), followed by infants born preterm-appropriate for gestational age and term-SGA. CONCLUSIONS The risk of mortality in infants born preterm and/or SGA is increased and extends through the second month of life. Appropriate interventions to prevent and manage complications caused by prematurity and SGA could improve survival during and beyond the neonatal period.

Abstract
BACKGROUND Prematurity represents a critical health disparity. It is important to note that late preterm (LPT) infants comprise the majority of preterm births, yet they are the least studied within the premature population. Evidence-based practice guidelines are now a decade old, indicating the potential need for review and revision. OBJECTIVES This systematic review proposed the assessment of sociodemographic characteristics of LPT infants, clinical practice standards, and associated hospital readmission rates, mortality, and morbidity to determine the need for revision of evidence-based practice guidelines for these infants. DATA SOURCES The Preferred Reporting System Items for Systematic Reviews and Meta Analysis methodology provided the framework for the completion of this review. Literature searches of PubMed/Medline (Ovid), Web of Science, Cumulative Index of Nursing, and Allied Health Literature Plus databases and citation searches included articles published after 2012 using the search terms "late preterm infants," "readmissions," and "readmission rates." CONCLUSIONS The literature search identified 11 studies meeting search criteria. These studies included quasi experimental, retrospective, and prospective cohort studies. These studies highlighted the characteristics of LPT infants that potentially contribute to increased readmission rates, morbidity and mortality rates, health care costs, and long-term health inequities. Overall findings indicate the need for review and revision of evidence-based practice guidelines for these infants. IMPLICATIONS FOR PRACTICE This systematic review manifests the vulnerability of LPT infants and the accompanying need for up-to-date clinical practice guidelines to effectively reduce their morbidity and mortality rates, hospital readmissions rates, and burden of health care costs.

Abstract
Successful pregnancy highly depends on the complex interaction between the uterine body, cervix, and fetal membrane. This interaction is synchronized, usually following a specific sequence in normal vaginal deliveries: (1) cervical ripening, (2) uterine contractions, and (3) rupture of fetal membrane. The complex interaction between the cervix, fetal membrane, and uterine contractions before the onset of labor is investigated using a complete third-trimester gravid model of the uterus, cervix, fetal membrane, and abdomen. Through a series of numerical simulations, we investigate the mechanical impact of (i) initial cervical shape, (ii) cervical stiffness, (iii) cervical contractions, and (iv) intrauterine pressure. The findings of this work reveal several key observations: (i) maximum principal stress values in the cervix decrease in more dilated, shorter, and softer cervices; (ii) reduced cervical stiffness produces increased cervical dilation, larger cervical opening, and decreased cervical length; (iii) the initial cervical shape impacts final cervical dimensions; (iv) cervical contractions increase the maximum principal stress values and change the stress distributions; (v) cervical contractions potentiate cervical shortening and dilation; (vi) larger intrauterine pressure (IUP) causes considerably larger stress values and cervical opening, larger dilation, and smaller cervical length; and (vii) the biaxial strength of the fetal membrane is only surpassed in the cases of the (1) shortest and most dilated initial cervical geometry and (2) larger IUP.

BMC Pregnancy Childbirth 2024; 24:334. [PMID: 38698318 PMCID: PMC11064281 DOI: 10.1186/s12884-024-06304-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 01/29/2024] [Indexed: 05/05/2024] Open
Abstract
BACKGROUND The aim of this study is to determine the effectiveness of antenatal corticosteroid in reducing respiratory morbidity in babies born in the late preterm period. METHODS Two hundred and eighty-six pregnant women at risk of having a late preterm delivery were studied. One hundred and forty-three (143) served as the cases and were given 2 doses of 12 mg intramuscular dexamethasone 12 h apart, while 143 served as the controls and were given a similar quantity of placebo. The women were followed up prospectively and data were collected on the pregnant women and their newborns on a standardized form. The neonates were assessed for acute respiratory distress syndrome and transient tachypnea of the newborn based on clinical signs, symptoms, and chest x-ray results (when indicated). The primary outcome was the occurrence of neonatal respiratory morbidity. RESULTS The primary outcome occurred in 5 out of 130 infants (3.8%) in the dexamethasone group and 31 out of 122 (25.4%) in the placebo group (P value = 0.000003). Birth asphyxia, neonatal intensive care admission and need for active resuscitation at birth also occurred significantly less frequently in the dexamethasone group (P value 0.004, 0.009, 0.014 respectively). There were no significant group differences in the incidence of neonatal sepsis, neonatal jaundice, hypoglycemia and feeding difficulties. CONCLUSIONS Administration of dexamethasone to women at risk for late preterm delivery significantly reduced the rate of neonatal respiratory complications, neonatal intensive care unit admission, and need for active resuscitation at birth.

Abstract
OBJECTIVE This study aimed to establish the degree of variability in thresholds for discussing withdrawal of life-sustaining therapies (WLST) in periviable infants among neonatal intensive care unit (NICU) personnel. STUDY DESIGN A vignette-style survey was administered to NICU personnel at two urban NICUs assessing likelihood of discussing WLST or support for discussing WLST (on a scale from 1, not at all likely/supportive to 10, extremely likely/supportive) in 10 clinical scenarios. RESULTS Response rates ranged by clinical role from 26 to 89%. Participant responses ranged from 1 to 10 in 5 out of 10 vignettes for NICU attendings, and 9 out of 10 vignettes for bedside nurses. Lower gestational age (22-23 vs. 24-25 weeks) was associated with increased likelihood to discuss WLST in some but not all scenarios. CONCLUSION NICU personnel have widely variable criteria for discussing WLST which threatens the informed consent process surrounding resuscitation decisions in a "trial of therapy" framework. KEY POINTS · NICU personnel have variable criteria for WLST.. · Parents have little say in whether WLST is offered.. · Disclosure of variable criteria is not routine..

Abstract
BACKGROUND Most moderate-to-late-preterm infants need nutritional support until they are feeding exclusively on their mother's breast milk. Evidence to guide nutrition strategies for these infants is lacking. METHODS We conducted a multicenter, factorial, randomized trial involving infants born at 32 weeks 0 days' to 35 weeks 6 days' gestation who had intravenous access and whose mothers intended to breast-feed. Each infant was assigned to three interventions or their comparators: intravenous amino acid solution (parenteral nutrition) or dextrose solution until full feeding with milk was established; milk supplement given when maternal milk was insufficient or mother's breast milk exclusively with no supplementation; and taste and smell exposure before gastric-tube feeding or no taste and smell exposure. The primary outcome for the parenteral nutrition and the milk supplement interventions was the body-fat percentage at 4 months of corrected gestational age, and the primary outcome for the taste and smell intervention was the time to full enteral feeding (150 ml per kilogram of body weight per day or exclusive breast-feeding). RESULTS A total of 532 infants (291 boys [55%]) were included in the trial. The mean (±SD) body-fat percentage at 4 months was similar among the infants who received parenteral nutrition and those who received dextrose solution (26.0±5.4% vs. 26.2±5.2%; adjusted mean difference, -0.20; 95% confidence interval [CI], -1.32 to 0.92; P = 0.72) and among the infants who received milk supplement and those who received mother's breast milk exclusively (26.3±5.3% vs. 25.8±5.4%; adjusted mean difference, 0.65; 95% CI, -0.45 to 1.74; P = 0.25). The time to full enteral feeding was similar among the infants who were exposed to taste and smell and those who were not (5.8±1.5 vs. 5.7±1.9 days; P = 0.59). Secondary outcomes were similar across interventions. Serious adverse events occurred in one infant. CONCLUSIONS This trial of routine nutrition interventions to support moderate-to-late-preterm infants until full nutrition with mother's breast milk was possible did not show any effects on the time to full enteral feeding or on body composition at 4 months of corrected gestational age.

Metabolomic analysis of the human placenta reveals perturbations in amino acids, purine metabolites, and small organic acids in spontaneous preterm birth. EXCLI JOURNAL 2024; 23:264-282.

Abstract
Spontaneous preterm delivery presents one of the most complex challenges in obstetrics and is a leading cause of perinatal morbidity and mortality. Although it is a common endpoint for multiple pathological processes, the mechanisms governing the etiological complexity of spontaneous preterm birth and the placental responses are poorly understood. This study examined placental tissues collected between May 2019 and May 2022 from a well-defined cohort of women who experienced spontaneous preterm birth (n = 72) and healthy full-term deliveries (n = 30). Placental metabolomic profiling of polar metabolites was performed using Ultra-High Performance Liquid Chromatography/Mass Spectrometry (UHPLC/MS) analysis. The resulting data were analyzed using multi- and univariate statistical methods followed by unsupervised clustering. A comprehensive metabolomic evaluation of the placenta revealed that spontaneous preterm birth was associated with significant changes in the levels of 34 polar metabolites involved in intracellular energy metabolism and biochemical activity, including amino acids, purine metabolites, and small organic acids. We found that neither the preterm delivery phenotype nor the inflammatory response explain the reported differential placental metabolome. However, unsupervised clustering revealed two molecular subtypes of placentas from spontaneous preterm pregnancies exhibiting differential enrichment of clinical parameters. We also identified differences between early and late preterm samples, suggesting distinct placental functions in early spontaneous preterm delivery. Altogether, we present evidence that spontaneous preterm birth is associated with significant changes in the level of placental polar metabolites. Dysregulation of the placental metabolome may underpin important (patho)physiological mechanisms involved in preterm birth etiology and long-term neonatal outcomes.

Abstract
OBJECTIVE The aim of this study was to investigate the role of cerebroplacental ratio (CPR) in the final prenatal care for neonatal respiratory diseases and to analyze the risk of relevant factors associated with neonatal respiratory disorders. METHODS A prospective cohort study of 795 singleton pregnancies was conducted. The pulsatility indices (PI) of the umbilical artery (UA) and the middle cerebral artery (MCA) were measured, and the MCA to UA ratio (CPR) was determined. The severity of the case is determined by whether or not the newborn has respiratory problems. Compare the CPR correlation between the two groups and examine the illness prediction factors through a binary logistic regression method. RESULTS Of the 795 participants, 124 had neonatal respiratory disorders. The mean values of CPR between neonatal respiratory diseases group and control group were 1.78±0.6, 1.97±0.9, respectively (P < 0.001). Maternal age, abortion history, cesarean section history, placental thickness, placental maturity, and amniotic fluid index (AFI) were determined to have no significant link between the two groups after comparison analysis (P > 0.05). It could be found that compared with the control group, CPR MoM indicators of neonatal respiratory distress syndrome, neonatal pneumonia and wet lung disease all show significant decreases. In binary logistic regression analysis, among the variables included in the model, CPR (OR:2.90, P = 0.015), fetal heart monitoring (OR:5.26, P < 0.001), delivery mode (OR:2.86, P < 0.001) and gestational age of delivery (OR:0.92, P < 0.001) were statistically significant in both groups. CONCLUSION The findings of this study showed that infant respiratory problems were substantially related to CPR value. The correlation indicates that CPR was a powerful reference marker for respiratory disorders.

Abstract
BACKGROUND The aim was to compare neonatal morbidities in moderate and late preterm infants and to analyze rates and causes for rehospitalizations during the first year of life. METHODS Prospective follow-up of a group of moderate and late preterm infants at a tertiary care hospital. RESULTS The study population comprised 215 infants (58% males; 60% singletons; 99 moderate and 116 late preterm infants) with a median gestational age of 34 weeks and birth weight of 2100 grams; 20% of them were small for gestational age. Moderate preterm infants more often had a diagnosis of mild respiratory distress syndrome (26% vs. 13%, P<0.01) and feeding problems with longer need for nasogastric tube feeding (median 9.5 vs. 4.2 days, P<0.01) and parenteral nutrition (3.5 vs. 2.7 days, P<0.01), and longer duration of stay at either NICU (10.6 vs. 3.7 days; P<0.01) or hospital (13 vs. 11 days; P<0.01). Fifty-two infants (24.3%) were hospitalized at 67 occasions without differences regarding readmission rates and causes between groups. Median age at readmission was 3 months, median stay 4 days. The most common diagnosis was respiratory illness (43.3%). CONCLUSIONS Moderate preterm infants had more neonatal morbidities diagnosed, but the same rehospitalization rates than late preterm infants.

Abstract
BACKGROUND The usefulness of cervical length (CL) measurement in asymptomatic pregnancies in the third trimester of pregnancy is not certain. Therefore, the objective of this study was to assess the performance of CL measurement at 31-34 gestational weeks for the prediction of spontaneous late preterm birth (PTB). MATERIALS AND METHODS This was a prospective study of women with a singleton pregnancy, who had their routine third-trimester scan at 31-34 weeks. The CL was measured transvaginally and was tested, together with maternal demographic and obstetric parameters, for the prediction of late PTB (34 to 36 weeks), using logistic regression and ROC curve analysis. RESULTS Overall, from a population of 1003 women that consented to participate in the study, 42 (4.2%) delivered at 34-36 gestational weeks. A significant association was identified between gestational age at birth and CL (rho = 0.182, p < .001), and there were significant differences in the CL between cases of late preterm and term births (p < .001). Cervical length alone could predict 17% of late PTB for a 10% false positive rate, corresponding to 22 mm. A model combining CL with parity and method of conception can identify 35% of pregnancies resulting in late PTB, at a false positive rate of 10% (AUC: 0.750; 95% CI: 0.675-0.824). CONCLUSIONS CL assessment at 31-34 gestational weeks may contribute to the prediction of late PTB when combined with maternal characteristics.

Abstract
BACKGROUND Preterm birth is the leading cause of neonatal mortality and is associated with long-term physical, neurodevelopmental, and socioeconomic effects. This study updated national preterm birth rates and trends, plus novel estimates by gestational age subgroups, to inform progress towards global health goals and targets, and aimed to update country, regional, and global estimates of preterm birth for 2020 in addition to trends between 2010 and 2020. METHODS We systematically searched population-based, nationally representative data on preterm birth from Jan 1, 2010, to Dec 31, 2020 and study data (26 March-14 April, 2021) for countries and areas with no national-level data. The analysis included 679 data points (86% nationally representative administrative data [582 of 679 data points]) from 103 countries and areas (62% of countries and areas having nationally representative administrative data [64 of 103 data points]). A Bayesian hierarchical regression was used for estimating country-level preterm rates, which incoporated country-specific intercepts, low birthweight as a covariate, non-linear time trends, and bias adjustments based on a data quality categorisation, and other indicators such as method of gestational age estimation. FINDINGS An estimated 13·4 million (95% credible interval [CrI] 12·3-15·2 million) newborn babies were born preterm (<37 weeks) in 2020 (9·9% of all births [95% CrI 9·1-11·2]) compared with 13·8 million (12·7-15·5 million) in 2010 (9·8% of all births [9·0-11·0]) worldwide. The global annual rate of reduction was estimated at -0·14% from 2010 to 2020. In total, 55·6% of total livebirths are in southern Asia (26·8% [36 099 000 of 134 767 000]) and sub-Saharan Africa (28·7% [38 819 300 of 134 767 000]), yet these two regions accounted for approximately 65% (8 692 000 of 13 376 200) of all preterm births globally in 2020. Of the 33 countries and areas in the highest data quality category, none were in southern Asia or sub-Saharan Africa compared with 94% (30 of 32 countries) in high-income countries and areas. Worldwide from 2010 to 2020, approximately 15% of all preterm births occurred at less than 32 weeks of gestation, requiring more neonatal care (<28 weeks: 4·2%, 95% CI 3·1-5·0, 567 800 [410 200-663 200 newborn babies]); 28-32 weeks: 10·4% [9·5-10·6], 1 392 500 [1 274 800-1 422 600 newborn babies]). INTERPRETATION There has been no measurable change in preterm birth rates over the last decade at global level. Despite increasing facility birth rates and substantial focus on routine health data systems, there remain many missed opportunities to improve preterm birth data. Gaps in national routine data for preterm birth are most marked in regions of southern Asia and sub-Saharan Africa, which also have the highest estimated burden of preterm births. Countries need to prioritise programmatic investments to prevent preterm birth and to ensure evidence-based quality care when preterm birth occurs. Investments in improving data quality are crucial so that preterm birth data can be improved and used for action and accountability processes.

Mekic N, Selimovic A, Cosickic A, Mehmedovic M, Hadzic D, Zulic E, Mustafic S, Serak A. Predictors of adverse short-term outcomes in late preterm infants. BMC Pediatr 2023; 23:298. [PMID: 37328827 PMCID: PMC10276478 DOI: 10.1186/s12887-023-04112-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 06/05/2023] [Indexed: 06/18/2023] Open
Abstract
BACKGROUND Infants born between 34 weeks and 36 weeks and 6 days of gestation are defined as late preterm infants (LPIs), and they account for approximately 74% of all premature births. Preterm birth (PB) remains the leading cause of infant mortality and morbidity worldwide. AIM To analyse short-term morbidity and mortality and identify predictors of adverse outcomes in late preterm infants. PATIENTS AND METHODS In this retrospective study, we evaluated adverse short-term outcomes of LPIs admitted to the Intensive Care Unit (ICU), Clinic for Children's Diseases, University Clinical Center Tuzla, between 01.01.2020 and 31.12.2022. The analysed data included sex, gestational age, parity, birth weight, Apgar score (i.e., assessment of vitality at birth in the first and fifth minutes after birth), and length of hospitalization in NICU, as well as short-term outcome data. Maternal risk factors we observed were: age of mother, parity, maternal morbidity during pregnancy, complications and treatment during pregnancy. LPIs with major anatomic malformations were excluded from the study. Logistic regression analysis was used to identify risk factors for neonatal morbidity among LPIs. RESULTS We analysed data from 154 late preterm newborns, most of whom were male (60%), delivered by caesarean Sect. (68.2%) and from nulliparous mothers (63.6%). Respiratory complications were the most common outcome among all subgroups, followed by CNS morbidity, infections and jaundice requiring phototherapy. The rate of almost all of the complications in the late-preterm group decreased as gestational age increased from 34 to 36 weeks. Birth weight (OR: 1,2; 95% CI: 0,9 - 2,3; p = 0,0313) and male sex (OR: 2,5; 95% CI: 1,1-5,4; p = 0,0204) were significantly and independently associated with an increased risk for respiratory morbidity, and gestational weeks and male sex were associated with infectious morbidity. None of the risk factors analysed herein were predictors of CNS morbidity in LPIs. CONCLUSION A younger gestational age at birth is associated with a greater risk of short-term complications among LPIs, thus highlighting the need for increased knowledge about the epidemiology of these late preterm births. Understanding the risks of late preterm birth is critical to optimizing clinical decision-making, enhancing the cost-effectiveness of endeavours to delay delivery during the late preterm period, and reducing neonatal morbidity.

Abstract
Despite major achievements in child survival, the burden of neonatal mortality has remained high and even increased in some countries since 1990. Currently, most neonatal deaths are attributable to being born preterm, small for gestational age (SGA), or with low birthweight (LBW). Besides neonatal mortality, these conditions are associated with stillbirth and multiple morbidities, with short-term and long-term adverse consequences for the newborn, their families, and society, resulting in a major loss of human capital. Prevention of preterm birth, SGA, and LBW is thus critical for global child health and broader societal development. Progress has, however, been slow, largely because of the global community's failure to agree on the definition and magnitude of newborn vulnerability and best ways to address it, to frame the problem attractively, and to build a broad coalition of actors and a suitable governance structure to implement a change. We propose a new definition and a conceptual framework, bringing preterm birth, SGA, and LBW together under a broader umbrella term of the small vulnerable newborn (SVN). Adoption of the framework and the unified definition can facilitate improved problem definition and improved programming for SVN prevention. Interventions aiming at SVN prevention would result in a healthier start for live-born infants, while also reducing the number of stillbirths, improving maternal health, and contributing to a positive economic and social development in the society.

Late preterm delivery has a distinctive second-stage duration and characteristics. Am J Obstet Gynecol MFM 2023; 5:100845. [PMID: 36572106 DOI: 10.1016/j.ajogmf.2022.100845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 12/06/2022] [Accepted: 12/20/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND Late preterm neonates born between 34.0 and 36.6 weeks' gestation are at increased risk for short- and long-term morbidity and mortality when compared with their term counterparts. Currently, no separate labor curve is available for late preterm births, and this group's optimal duration of the second stage of labor has never been defined separately. OBJECTIVE This study aimed to compare the second stage duration between late preterm and term births. STUDY DESIGN This was a retrospective study from May 2014 until May 2021. Eligible were women with a singleton pregnancy, vertex presentation, spontaneous or induced onset of labor, and those who delivered vaginally beyond 34.0 weeks of gestation. The primary outcome of our study was to compare and characterize the second stage of labor duration between late preterm and term births. RESULTS We analyzed 962 late preterm and 9476 term vaginal deliveries. Women who delivered during the late preterm period were more likely to be multiparous (52.4% vs 45.2%; P<.001) and fewer required oxytocin during labor (41.2% vs 54.4%; P<.001) or used epidural analgesia (75.2% vs 83.6%; P<.001). The overall mean duration of the second stage of labor was significantly shorter in the late preterm period than at term (1.08±1.09 hours vs 1.49±1.22 hours; P<.001). This was even more pronounced for nulliparous women (1.05±1.00 hours vs 2.10±1.17 hours; P<.001). Among multiparous women, epidural use significantly affected the duration of the second stage of labor, and the second stage was relatively longer during the late preterm period than at term in this subgroup (1.16 vs 0.5 hours; P<.001). Using a multivariate Cox regression, variables such as maternal age (hazard ratio, 1.02; 95% confidence interval, 1.01-1.04), parity (hazard ratio, 4.11; 95% confidence interval, 3.65-4.63), preterm birth (hazard ratio, 2.08; 95% confidence interval, 1.4-3.10), and birthweight at delivery (hazard ratio, 1.15; 95% confidence interval, 1.01-1.30) shortened the second stage, whereas induction of labor (hazard ratio, 0.75; 95% confidence interval, 0.66-0.86) and epidural use (hazard ratio, 0.68; 95% confidence interval, 0.64-0.86) extended its total duration. Regardless of parity, lower rates of operative vaginal deliveries were observed in the late preterm period than at term (3.7% vs 15.5%; P<.001). This period was also associated with lower rates of third- and fourth-degree perineal lacerations (0.2% vs 2.2%; P<.001) but higher rates of chorioamnionitis (1.7% vs 0.1%; P<.001), Apgar score at 5 minutes <7 (1.0% vs 0.2%; P<.001), and admission to the neonatal intensive care unit (19.3% vs 1.0%; P<.001). CONCLUSION Women who delivered vaginally during the late preterm period had a distinctive second-stage duration. Primarily, it was shown to be significantly shorter for nulliparous and multiparous women. Future studies should further clarify the optimal duration of this stage in relation to neonatal outcomes at such a vulnerable period.

Abstract
Importance A higher level of care improves outcomes in extremely and very preterm infants, yet the impact of neonatal intensive care unit (NICU) level on moderate and late preterm (MLP) care quality is unknown. Objective To examine the association between NICU type and care quality in MLP (30-36 weeks' gestation) and extremely and very preterm (25-29 weeks' gestation) infants. Design, Setting, and Participants This cohort study was a prospective analysis of 433 814 premature infants born in 465 US hospitals between January 1, 2016, and December 31, 2020, without anomalies and who survived more than 12 hours and were transferred no more than once. Data were from the Vermont Oxford Network all NICU admissions database. Exposures NICU types were defined as units with ventilation restrictions without surgery (type A with restrictions, similar to American Academy of Pediatrics [AAP] level 2 NICUs), without surgery (type A) and with surgery not requiring cardiac bypass (type B, similar to AAP level 3 NICUs), and with all surgery (type C, similar to AAP level 4 NICUs). Main Outcomes and Measures The primary outcome was gestational age (GA)-specific composite quality measures using Baby-Measure of Neonatal Intensive Care Outcomes Research (Baby-MONITOR) for extremely and very preterm infants and an adapted MLP quality measure for MLP infants. Secondary outcomes were individual component measures of each scale. Composite scores were standardized observed minus expected scores, adjusted for patient characteristics, averaged, and expressed with a mean of 0 and SD of 1. Between May 2021 and October 2022, Kruskal-Wallis tests were used to compare scores by NICU type. Results Among the 376 219 MLP (204 181 [54.3%] male, 172 038 [45.7%] female; mean [SD] GA, 34.2 [1.7] weeks) and 57 595 extremely and very preterm (30 173 [52.4%] male, 27 422 [47.6%] female; mean [SD] GA, 27.7 [1.4] weeks) infants included, 6.6% received care in type A NICUs with restrictions, 29.3% in type A NICUs without restrictions, 39.7% in type B NICUs, and 24.4% in type C NICUs. The MLP infants had lower MLP-QM scores in type C NICUs (median [IQR]: type A with restrictions, 0.4 [-0.1 to 0.8]; type A, 0.4 [-0.4 to 0.9]; type B, 0.1 [-0.7 to 0.7]; type C, -0.7 [-1.6 to 0.4]; P < .001). No significant differences were found in extremely and very preterm Baby-MONITOR scores by NICU type. In type C NICUs, MLP infants had lower scores in no extreme length of stay and change-in-weight z score. Conclusions and Relevance In this cohort study, composite quality scores were lower for MLP infants in type C NICUs, whereas extremely and very preterm composite quality scores were similar across NICU types. Policies facilitating care for MLP infants at NICUs with less complex subspecialty services may improve care quality delivered to this prevalent, at-risk population.

Abstract
Background The autonomic nervous system of preterm fetuses has a different level of maturity than term fetuses. Thus, their autonomic response to transient hypoxemia caused by uterine contractions in labor may differ. This study aims to compare the behavior of the fetal autonomic response to uterine contractions between preterm and term active labor using a novel time-frequency analysis of fetal heart rate variability (FHRV). Methods We performed a case-control study using fetal R-R and uterine activity time series obtained by abdominal electrical recordings from 18 women in active preterm labor (32-36 weeks of gestation) and 19 in active term labor (39-40 weeks of gestation). We analyzed 20 minutes of the fetal R-R time series by applying a Continuous Wavelet Transform (CWT) to obtain frequency (HF, 0.2-1 Hz; LF, 0.05-0.2 Hz) and time-frequency (Flux0, Flux90, and Flux45) domain features. Time domain FHRV features (SDNN, RMSSD, meanNN) were also calculated. In addition, ultra-short FHRV analysis was performed by segmenting the fetal R-R time series according to episodes of the uterine contraction and quiescent periods. Results No significant differences between preterm and term labor were found for FHRV features when calculated over 20 minutes. However, we found significant differences when segmenting between uterine contraction and quiescent periods. In the preterm group, the LF, Flux0, and Flux45 were higher during the average contraction episode compared with the average quiescent period (p<0.01), while in term fetuses, vagally mediated FHRV features (HF and RMSSD) were higher during the average contraction episode (p<0.05). The meanNN was lower during the strongest contraction in preterm fetuses compared to their consecutive quiescent period (p=0.008). Conclusion The average autonomic response to contractions in preterm fetuses shows sympathetic predominance, while term fetuses respond through parasympathetic activity. Comparison between groups during the strongest contraction showed a diminished fetal autonomic response in the preterm group. Thus, separating contraction and quiescent periods during labor allows for identifying differences in the autonomic nervous system cardiac regulation between preterm and term fetuses.

Abstract
Background Preterm birth is a major public health concern with the largest burden of morbidity and mortality falling within low- and middle-income countries (LMIC). Materials and methods This sequential explanatory mixed methods study was conducted in special care baby units (SCBUs) serving migrants and refugees along the Myanmar-Thailand border. It included a retrospective medical records review, qualitative interviews with mothers receiving care within SCBUs, and focus group discussions with health workers. Changes in neonatal mortality and four clinical outcomes were described. A mix of ethnographic phenomenology and implementation frameworks focused on cultural aspects, the lived experience of participants, and implementation outcomes related to SCBU care. Results From 2008-2017, mortality was reduced by 68% and 53% in very (EGA 28-32 weeks) and moderate (EGA 33-36 weeks) preterm neonates, respectively. Median SCBU stay was longer in very compared to moderate preterm neonates: 35 (IQR 22, 48 days) vs. 10 days (IQR 5, 16). Duration of treatments was also longer in very preterm neonates: nasogastric feeding lasted 82% (IQR 74, 89) vs. 61% (IQR 40, 76) of the stay, and oxygen therapy was used a median of 14 (IQR 7, 27) vs. 2 (IQR 1, 6) days respectively. Nine interviews were conducted with mothers currently receiving care in the SCBU and four focus group discussions with a total of 27 local SCBU staff. Analysis corroborated quantitative analysis of newborn care services in this setting and incorporated pertinent implementation constructs including coverage, acceptability, appropriateness, feasibility, and fidelity. Coverage, acceptability, and appropriateness were often overlapping outcomes of interest highlighting financial issues prior to or while admitted to the SCBU and social issues and support systems adversely impacting SCBU stays. Interview and FGD findings highlight the barriers in this resource-limited setting as they impact the feasibility and fidelity of providing evidence-based SCBU care that often required adaptation to fit the financial and environmental constraints imposed by this setting. Discussion This study provides an in-depth look at the nature of providing preterm neonatal interventions in a SCBU for a vulnerable population in a resource-limited setting. These findings support implementation of basic evidence-based interventions for preterm and newborn care globally, particularly in LMICs.

PLoS One 2022; 17:e0279385. [PMID: 36548293 PMCID: PMC9778627 DOI: 10.1371/journal.pone.0279385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Accepted: 12/06/2022] [Indexed: 12/24/2022] Open
Abstract
Preterm delivery is greatly associated with perinatal mortality and morbidity, while there is no objective way to identify high-risk newborns currently. This study aimed at discovering the risk factor for Apgar score less than 7 at 1 minute of preterm neonates born with vaginal delivery. A retrospective study was performed in single pregnancy women with a vaginal delivery before 37 weeks of gestation. All the preterm infants were categorized into three types: very preterm birth (28 to 32 weeks), moderate preterm birth (32 to 34 weeks) and late preterm birth (34 to 37 weeks). Risk factors were identified through logistic regression analysis in every category of newborns mentioned above. And the receiver operating characteristic analysis was used in continuous variables to determine the best threshold of the outcome. On the basis of the selected factors, the predicting models are created and its prognosticating ability is compared by the area under the curve. A nomogram was established for the proved best model. A total of 981 cases were investigated, of whom 55 were found with 1 min Apgar scores less than 7. The nomogram was set for the predicting model with larger area under the receiver operating characteristic curve, of which is 0.742(95% confidence interval = 0.670-0.805) in very preterm birth, with the variables of first and second labor stage(> = 1.6 hours), birthweight and MgSO4(magnesium sulfate), and is 0.807(95% confidence interval = 0.776-0.837) in late preterm birth, with the variables of second labor stage(> = 1.23 hours), birthweight, a history of previous cesarean delivery, fetal distress and placental abruption. The combination of first and second labor stage, newborn weight and MgSO4 use can predict 74.2% of 1 minute Apgar score < 7 in very preterm neonates. And 80.7% high-risk infants can be identified when second labor stage, newborn weight, VBAC (vaginal birth after cesarean) and the occur of placental abruption and fetal distress were combined in the predicting model for late preterm birth. These predicting models would bring out great assistance towards obstetricians and reduce unnecessary adverse fetal outcomes.

[PMID: 35470904 PMCID: PMC9790712 DOI: 10.1111/birt.12642] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 02/22/2022] [Accepted: 04/07/2022] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To determine the epidemiology, clinical management, and outcomes of women with gestational breast cancer (GBC). METHODS A population-based prospective cohort study was conducted in Australia and New Zealand between 2013 and 2014 using the Australasian Maternity Outcomes Surveillance System (AMOSS). Women who gave birth with a primary diagnosis of breast cancer during pregnancy were included. Data were collected on demographic and pregnancy factors, GBC diagnosis, obstetric and cancer management, and perinatal outcomes. The main outcome measures were preterm birth, maternal complications, breastfeeding, and death. RESULTS Forty women with GBC (incidence 7.5/100 000 women giving birth) gave birth to 40 live-born babies. Thirty-three (82.5%) women had breast symptoms at diagnosis. Of 27 women diagnosed before 30 weeks' gestation, 85% had breast surgery and 67% had systemic therapy during pregnancy. In contrast, all 13 women diagnosed from 30 weeks had their cancer management delayed until postdelivery. There were 17 preterm deliveries; 15 were planned. Postpartum complications included the following: hemorrhage (n = 4), laparotomy (n = 1), and thrombocytopenia (n = 1). There was one late maternal death. Eighteen (45.0%) women initiated breastfeeding, including 12 of 23 women who had antenatal breast surgery. There were no perinatal deaths or congenital malformations, but 42.5% of babies were preterm, and 32.5% were admitted for higher-level neonatal care. CONCLUSIONS Gestational breast cancer diagnosed before 30 weeks' gestation was associated with surgical and systemic cancer care during pregnancy and planned preterm birth. In contrast, cancer treatment was deferred to postdelivery for women diagnosed from 30 weeks, reflecting the complexity of managing expectant mothers with GBC in multidisciplinary care settings.

Transcriptomic analysis of the human placenta reveals trophoblast dysfunction and augmented Wnt signalling associated with spontaneous preterm birth. Front Cell Dev Biol 2022; 10:987740. [DOI: 10.3389/fcell.2022.987740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 10/13/2022] [Indexed: 11/13/2022] Open
Abstract
Preterm birth (PTB) is the leading cause of death in under-five children. Worldwide, annually, over 15 million babies are born preterm and 1 million of them die. The triggers and mechanisms of spontaneous PTB remain largely unknown. Most current therapies are ineffective and there is a paucity of reliable predictive biomarkers. Understanding the molecular mechanisms of spontaneous PTB is crucial for developing better diagnostics and therapeutics. To address this need, we conducted RNA-seq transcriptomic analysis, qRT-PCR and ELISA on fresh placental villous tissue from 20 spontaneous preterm and 20 spontaneous term deliveries, to identify genes and signalling pathways involved in the pathogenesis of PTB. Our differential gene expression, gene ontology and pathway analysis revealed several dysregulated genes (including OCLN, OPTN, KRT7, WNT7A, RSPO4, BAMBI, NFATC4, SLC6A13, SLC6A17, SLC26A8 and KLF8) associated with altered trophoblast functions. We identified dysregulated Wnt, oxytocin and cellular senescence signalling pathways in preterm placentas, where augmented Wnt signalling could play a pivotal role in the pathogenesis of PTB due to its diverse biological functions. We also reported two novel targets (ITPR2 and MYLK2) in the oxytocin signalling pathways for further study. Through bioinformatics analysis on DEGs, we identified four key miRNAs, - miR-524-5p, miR-520d-5p, miR-15a-5p and miR-424-5p - which were significantly downregulated in preterm placentas. These miRNAs may have regulatory roles in the aberrant gene expressions that we have observed in preterm placentas. We provide fresh molecular insight into the pathogenesis of spontaneous PTB which may drive further studies to develop new predictive biomarkers and therapeutics.

Abstract
OBJECTIVE To examine quality measures for moderate and late preterm (MLP) infants. STUDY DESIGN By prospectively analyzing Vermont Oxford Network's all NICU admissions database, we adapted Baby-MONITOR, a composite quality measure for extremely/very preterm infants, for MLP infants. We examined correlations between the adapted MLP quality measure (MLP-QM) in MLP infants and Baby-MONITOR in extremely and very preterm infants. RESULT We studied 376,219 MLP (30-36 weeks GA) and 57,595 extremely/very preterm (25-29 weeks GA) infants from 465 U.S. hospitals born from 2016 to 2020. MLP-QM summary scores in MLP infants had weak correlation with Baby-MONITOR scores in extremely and very preterm infants (r = 0.47). There was weak correlation among survival (r = 0.19), no pneumothorax (r = 0.35), and no infection after 3 days (r = 0.45), but strong correlation among human milk at discharge (r = 0.79) and no hypothermia (r = 0.76). CONCLUSION Modest correlation among hospital care measures in two preterm populations suggests the need for MLP-specific care measures.

Abstract
Prematurity represents 10.6% of all births, and although preterm infants usually show adequate neurodevelopmental outcomes, some may develop significant and long-lasting neurological sequelae. Many studies have analyzed predictive factors for developing severe neurodevelopmental impairments (cerebral palsy, other motor and socio-relational disorders such as autism). In this study, 148 preterm infants were enrolled to investigate the neurodevelopmental trajectories in a population of low-risk premature infants using standardized assessment methods. Significant correlations were found between the general movements, the Hammersmith Infant Neurological Examination, and the Griffiths Mental and Development Scales. Moreover, this study showed their validity and predictivity for adverse neurodevelopmental outcomes even in low-risk infants.

Abstract
Background: Late preterm (340−366 weeks gestational age [GA]) infants may have abnormal pulmonary development and possible exercise physiology parameters. We aim to assess the effect of late prematurity on exercise capacity in childhood and to compare it to early preterm (EP) (born < 300 GA), and to term healthy control (TC) (>370 week GA). Methods: Late preterm and early preterm (7−10 years) completed a cardiopulmonary exercise test (CPET) and spirometry and were compared to EP and to TC. Results: Eighty-four children (age 9.6 ± 1.0 years, 48% girls) participated. Twenty-one former LP were compared to 38 EP (15 with Bronchopulmonary dysplasia (BPD) [EP+], 23 without BPD [EP−]) and to 25 TC children. Peak oxygen uptake (peakV̇O2) was statistically lower than in the TC, but within the normal range, and without difference from the EP (LP 90.2 ± 15.1%, TC 112.4 ± 16.9%, p < 0.001; EP+ 97.3 ± 25.5%, EP− 85.4 ± 20.8%, p = 0.016 and p < 0.001, respectively, when compared with TC). Lung function (FEV1) was lower than normal only in the EP+ (75.6 ± 14.9% predicted, compared with 12.5 ± 87.8 in EP−, 87.5 ± 16.9 in LP and 91.0 ± 11.7 in TC). Respiratory and cardiac limitations were similar between all four study groups. Conclusions: This study demonstrated lower exercise capacity (peakV̇O2) in former LP children compared with healthy term children. Exercise capacity in LP was comparable to that of EP, with and without BPD. However, the exercise test parameters, specifically peakV̇O2, were within the normal range, and no significant physiological exercise limitations were found.

Abstract
Background and Objectives: There are limited data regarding the incidence and risk factors for hypoglycemia, hyperglycemia, and unstable glycemia in preterm infants. The aim of the present study was to determine the incidence and risk factors associated with neonatal hypoglycemia, hyperglycemia, and unstable glycemia in preterm infants during the first seven days of life. Materials and Methods: This prospective study included preterm infants <37 weeks of gestation, admitted to the Neonatal Intensive Care Unit between January 2018 and December 2020. Based on blood glucose levels in the first week of life, infants were divided into the following four groups: normoglycemic, hypoglycemic, hyperglycemic, and unstable. Blood glucose levels were measured from capillary blood at the 1st, 3rd, 6th, and 12th hour of life during the first 24 h, and at least once a day from days 2 to 7, prefeed. Results: Of 445 enrolled infants, 20.7% (92/445) were categorized as hypoglycemic, 9.9% (44/445) as hyperglycemic, and 2.9% (13/445) as unstable, respectively. Hypoglycemia was most commonly observed among infants ≥34 weeks (27.9%), and hyperglycemia was most common among preterm infants <28 weeks (50%). Female gender increased the chances of developing hypoglycemia by three times. The decrease in gestational age by one week increased the chance of developing hyperglycemia by 1.9 times. Sepsis increased the chance of developing hyperglycemia seven times, respiratory distress syndrome five times, and mechanical ventilation three times, respectively. Conclusions: Glucose disturbances in the early neonatal period in preterm infants are common and mostly asymptomatic. Therefore, careful blood glucose level monitoring is required in those infants, especially in late preterm infants, in order to prevent possible neurological complications.

Abstract
OBJECTIVE To establish a classification model for the evaluation of rat fetal lung maturity (FLM) using radiomics technology. METHOD A total of 430 high-throughput features were extracted per fetal lung image from 134 fetal lung ultrasound images (four-cardiac-chamber views) of 67 Sprague-Dawley (SD) fetal rats with gestational age (GA) of 16-21 days. The detection of fetal lung tissues included histopathological staining and the expression of the surface protein (SP) SP-A, SP-B, and SP-C. A machine learning classification model was established by a support vector machine based on histopathological results to analyze the relationship between fetal lung texture characteristics and FLM. RESULTS The rat fetal lungs were divided into two groups: terminal sac period (SD1) and canalicular period (SD2). The mRNA transcription and protein expression level of SP-C protein were significantly higher in the SD1 group than in the SD2 group (P < 0.05). The diagnostic performance of the rat FLM classification model was measured as follows: area under the receiver operating characteristic curve (AUC), 0.93 (training set) and 0.89 (validation set); sensitivity, 89.26% (training set) and 87.10% (validation set); specificity, 85.87% (training set) and 79.17% (validation set); accuracy, 87.79% (training set) and 83.64% (validation set). CONCLUSION Ultrasound-based radiomics technology can be used to evaluate the FLM of rats, which lays a foundation for further research on this technology in human fetal lungs.

Abstract
BACKGROUND Although delivery room (DR) intervention decreases with increasing gestational age (GA), little is known about DR management of moderate and late preterm (MLP) infants. METHODS Using the Vermont Oxford Network database of all NICU admissions, we examined the receipt of DR interventions including supplemental oxygen, positive pressure ventilation, continuous positive airway pressure, endotracheal tube ventilation, chest compressions, epinephrine, and surfactant among MLP infants (30 to 36 weeks') without congenital anomalies born from 2011 to 2020. Pneumothorax was examined as a potential resuscitation-associated complication. Intervention frequency was assessed at the infant- and hospital-level, stratified by GA and over time. RESULTS Overall, 55.3% of 616 110 infants (median GA: 34 weeks) from 483 Vermont Oxford Network centers received any DR intervention. Any DR intervention frequency decreased from 89.7% at 30 weeks to 44.2% at 36 weeks. From 2011 to 2020, there was an increase in the provision of continuous positive airway pressure (17.9% to 47.8%, P ≤.001) and positive pressure ventilation (22.9% to 24.9%, P ≤.001) and a decrease in endotracheal tube ventilation (6.9% to 4.0% P ≤.001), surfactant administration (3.5% to 1.3%, P ≤.001), and pneumothorax (1.9% to 1.6%, P ≤.001). Hospital rates of any DR intervention varied (median 54%, interquartile range 47% to 62%), though the frequency was similar across hospitals with different NICU capabilities after adjustment. CONCLUSIONS The DR management of MLP infants varies at the individual- and hospital-level and is changing over time. These findings illustrate the differing interpretation of resuscitation guidelines and emphasize the need to study MLP infants to improve evidence-based DR care.

Abstract
To develop a novel method for predicting neonatal respiratory morbidity (NRM) by ultrasound-based radiomics technology. In this retrospective study, 430 high-throughput features per fetal-lung image were extracted from 295 fetal lung ultrasound images (four-chamber view) in 295 single pregnancies. Images had been obtained between 28+3 and 37+6 weeks of gestation within 72 h before delivery. A machine-learning model built by RUSBoost (Random under-sampling with AdaBoost) architecture was created using 20 radiomics features extracted from the images and 2 clinical features (gestational age and pregnancy complications) to predict the possibility of NRM. Of the 295 standard fetal lung ultrasound images included, 210 in the training set and 85 in the testing set. The overall performance of the neonatal respiratory morbidity prediction model achieved AUC of 0.88 (95% CI 0.83–0.92) in the training set and 0.83 (95% CI 0.79–0.97) in the testing set, sensitivity of 84.31% (95% CI 79.06–89.44%) in the training set and 77.78% (95% CI 68.30–87.43%) in the testing set, specificity of 81.13% (95% CI 78.16–84.07%) in the training set and 82.09% (95% CI 77.65–86.62%) in the testing set, and accuracy of 81.90% (95% CI 79.34–84.41%) in the training set and 81.18% (95% CI 77.33–85.12%) in the testing set. Ultrasound-based radiomics technology can be used to predict NRM. The results of this study may provide a novel method for non-invasive approaches for the prenatal prediction of NRM.

Abstract
Amaç: Bu çalışmada sistemik immün-inflamatuar indeksin (SII) hamile kadınlarda erken doğum gelişimini tahmin edip edemeyeceği araştırılmıştır.
Gereç ve Yöntem: 1 Ocak 2018-31 Aralık 2021 tarihleri arasında kliniğimize spontan doğum eylemi ile başvuran, membranları intakt olan ve tek canlı fetüsü olan 18 yaş ve üstü gebeler retrospektif olarak değerlendirildi. Kadınlar doğum haftasına göre preterm ve term doğum olmak üzere iki gruba ayrıldı. Kadınların klinik ve laboratuvar özellikleri değerlendirildi. Hastaların trombosit-lenfosit oranı (PLR), nötrofil-lenfosit oranı (NLR) ve SII (nötrofil sayısı x trombosit sayısı/lenfosit sayısı) hesaplandı.
Bulgular: Çalışmaya erken doğum yapan 171 kadın ve sağlıklı term doğum yapan 173 kadın dahil edildi. PLR, NLR ve SII değerleri preterm grupta term grubuna göre istatistiksel olarak anlamlı derecede yüksekti. Çok değişkenli lojistik regresyon analizi, SII'nin (olasılık oranı [OR]: 3.65, %95 güven aralığı [GA]: 2.21–10.07) erken doğum gelişiminin bağımsız bir prediktör olduğunu gösterdi. SII'nin erken doğumu (eğrinin altındaki alan [AUC]: 0.792) tahmin etme gücünün, tek başına NLR (AUC: 0.725) veya PLR'den (AUC: 0.716) daha yüksek olduğunu bulduk. 789.3'ün üzerindeki SII değerleri, %68,4 duyarlılık ve %81.5 özgüllük ile erken doğumu öngördü.
Sonuç: Preterm doğumun erken tespitinde SII’nın NLR ve PLR’den daha değerli olduğunu bulduk. SII, preterm doğum gelişme riski taşıyan gebelerin erken dönemde belirlenmesine yardımcı olabilir.

Abstract
INTRODUCTION We aimed to generate evidence about child development measured through school attainment and provision of special educational needs (SEN) across the spectrum of gestational age, including for children born early term and >41 weeks of gestation, with and without chronic health conditions. METHODS We used a national linked dataset of hospital and education records of children born in England between 1 September 2004 and 31 August 2005. We evaluated school attainment at Key Stage 1 (KS1; age 7) and Key Stage 2 (KS2; age 11) and any SEN by age 11. We stratified analyses by chronic health conditions up to age 2, and size-for-gestation, and calculated population attributable fractions (PAF). RESULTS Of 306 717 children, 5.8% were born <37 weeks gestation and 7.0% had a chronic condition. The percentage of children not achieving the expected level at KS1 increased from 7.6% at 41 weeks, to 50.0% at 24 weeks of gestation. A similar pattern was seen at KS2. SEN ranged from 29.0% at 41 weeks to 82.6% at 24 weeks. Children born early term (37-38 weeks of gestation) had poorer outcomes than those born at 40 weeks; 3.2% of children with SEN were attributable to having a chronic condition compared with 2.0% attributable to preterm birth. CONCLUSIONS Children born with early identified chronic conditions contribute more to the burden of poor school outcomes than preterm birth. Evaluation is needed of how early health characteristics can be used to improve preparation for education, before and at entry to school.

Abstract
OBJECTIVE We evaluated the best time to initiate delivery in late preterm pre-eclampsia in order to optimise long-term infant and maternal outcomes. DESIGN Parallel-group, non-masked, randomised controlled trial. SETTING Forty-six maternity units in the UK. POPULATION Women with pre-eclampsia between 34+0 and 36+6 weeks of gestation, without severe disease, were randomised to planned delivery or expectant management. MAIN OUTCOME MEASURES Infant neurodevelopmental outcome at 2 years of age, using the Parent Report of Children's Abilities - Revised (PARCA-R) composite score. RESULTS Between 29 September 2014 and 10 December 2018, 901 women were enrolled in the trial, with 450 women allocated to planned delivery and 451 women allocated to expectant management. At the 2-year follow-up, the intention-to-treat analysis population included 276 women (290 infants) allocated to planned delivery and 251 women (256 infants) allocated to expectant management. The mean composite standardised PARCA-R scores were 89.5 (SD 18.2) in the planned delivery group and 91.9 (SD 18.4) in the expectant management group, with an adjusted mean difference of -2.4 points (95% CI -5.4 to 0.5 points). CONCLUSIONS In infants of women with late preterm pre-eclampsia, the average neurodevelopmental assessment at 2 years lies within the normal range, regardless of whether planned delivery or expectant management was pursued. With the lower than anticipated follow-up rate there was limited power to demonstrate that these scores did not differ, but the small between-group difference in PARCA-R scores is unlikely to be clinically important.

Lung mechanics and respiratory morbidities in school-age children born moderate-to-late preterm. Pediatr Res 2022; 91:1136-1140.

Abstract
BACKGROUND Late and moderate prematurity may have an impact on pulmonary function during childhood. The present study aimed to investigate lung mechanics in school-age children born moderate-to-late preterm (MLPT). METHODS Children aged 5-10 years were enrolled in this case-control study. Lung function and bronchodilator response were assessed by impulse oscillometry (IOS) at two hospital-based specialized clinics. A structured questionnaire was employed to assess respiratory morbidities. RESULTS A total of 123 children was divided into two groups: case (MLPT) n = 52 and control (children born at term) n = 71. The results showed no difference between groups in mean baseline IOS variables: R5 0.80 ± 0.20 vs 0.82 ± 0.22 kPa/L/s, p = 0.594, R20 0.54 ± 0.13 vs 0.55 ± 0.13 kPa/L/s, p = 0.732, R5-R20 0.26 ± 0.12 vs 0.27 ± 0.15 kPa/L/s, p = 0.615, X5 -0.29 ± 0.01 vs -0.29 ± 0.1 kPa/L/s, p = 0.990, Fres 21.1 ± 3.3 vs 21.7 ± 3.1 L/s, p = 0.380, and AX 2.7 ± 3.36 vs 2.5 ± 1.31 kPa/L/s, p = 0.626. Bronchodilator response and the occurrence of respiratory morbidities after birth were also similar between groups. CONCLUSIONS This study found lung mechanics parameters to be similar in school-age children born MLPT and those born at term, suggesting that pulmonary plasticity continues to occur in children up to school age. IMPACT Late and moderate prematurity is associated with an increased risk of reduced pulmonary function during childhood. Follow-up reports in adolescents and adults born MLPT are scarce but have indicated pulmonary plasticity with normalization of airway function. Our results show that the lung function in school-age children born MLPT is similar to that of children born at term.

Abstract
INTRODUCTION To determine the impact of route of delivery on maternal outcomes among individuals who deliver preterm (before 37 weeks). MATERIALS AND METHODS This was a population-based retrospective cohort study using the U.S. vital statistics datasets on Period Linked Birth-Infant Death Data from 2014 to 2018. The study population was restricted to live births from women with non-anomalous singletons who delivered at 24-36 weeks of gestation. The main explanatory variable for this study was route of delivery, which was categorized as: (i) vaginal delivery, (ii) cesarean delivery with labor, and (iii) cesarean delivery without labor. The primary outcome was composite maternal adverse outcome, which encompassed any of the following: admission to the intensive care unit, maternal blood transfusion, uterine rupture, or unplanned hysterectomy. The results were presented as adjusted relative risk (aRR) with 95% confidence interval (CI). RESULTS Over the study period 1,440,510 live births met the inclusion criteria, and the overall composite maternal adverse outcome was 14.38 per 1,000 live births. After multivariable adjustment, compared to women who underwent a vaginal delivery, the risk of composite maternal adverse outcome was higher in women who had a cesarean delivery with labor (aRR 3.70; 95% CI 3.52-3.90) and those who had a cesarean delivery without labor (aRR 4.79; 95% CI 4.59-4.98). CONCLUSION With preterm birth, cesarean delivery without labor has higher rate of composite maternal morbidity than cesarean during labor or vaginal delivery.

Abstract
BACKGROUND There is currently insufficient evidence on the safety and efficacy of antenatal corticosteroids in preventing mortality and severe morbidity amongst late preterm newborns in low-resource countries. METHODS We conducted a double-blind, randomized trial in four hospitals in India between 26 December 2017 to 21 May 2020. Pregnant women at risk of imminent preterm birth between 34 weeks 0 days and 36 weeks 0 days of gestation were recruited. Women were randomly assigned (1:1) to a course of 6 mg intramuscular dexamethasone or an identical placebo. All trial participants, research staff and outcome assessors were masked to allocation. Primary outcomes were neonatal death, any baby death (stillbirth or neonatal death), severe neonatal respiratory distress and possible maternal bacterial infection. The study was registered with ANZCTR (ACTRN12617001494325) and CTRI (CTRI/2017/05/008721). FINDINGS We randomized 782 women, 391 to each arm. Neonatal death occurred in 11 of 412 liveborn babies (2.7%) in the dexamethasone group and 12 of 425 liveborn babies (2.8%) in the placebo group (RR 0.95; 95% CI 0.42-2.12). Any baby death occurred in 16 of 417 infants (3.8%) in the dexamethasone group and 19 of 432 infants (4.4%) in the placebo group (RR 0.87; 95% CI 0.45-1.67). Severe neonatal respiratory distress was infrequent in both groups (0.8% vs 0.5%; RR 1.56; 95% CI 0.26-9.29). Possible maternal bacterial infection did not differ between groups (2.3% vs. 3.8%, RR 0.60; 95% CI 0.27-1.35). Fewer neonates in the dexamethasone group required resuscitation at birth (RR 0.38, CI 0.15-0.97). Other secondary outcomes were similar in the two arms. The trial was stopped due to lower than expected prevalence of primary outcomes and slow recruitment. INTERPRETATION Antenatal dexamethasone did not result in a reduction in neonatal death, stillbirth or neonatal death, or severe neonatal respiratory distress in this trial. The overall trend of effects suggests that potential benefit of dexamethasone in late preterm cannot be excluded, and further trials are required. FUNDING This trial was primarily funded by the Bill and Melinda Gates Foundation (Grant OPP1136821). Additional support was provided by UNDP/UNFPA/UNICEF/WHO/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), Department of Sexual and Reproductive Health and Research; and Department of Maternal, Newborn, Child, Adolescent Health, and Ageing, of the World Health Organization, Geneva, Switzerland.

Abstract
Introducción. La Organización Mundial de la Salud recomienda focalizar la atención en el período neonatal, eliminar la mortalidad de causa prevenible y brindar cuidados de calidad. Es esencial conocer cuáles son las condiciones con alta probabilidad de ocurrencia en esa población para monitorearlos de forma sistemática, de modo que se logre su detección temprana; y el abordaje terapéutico y rehabilitación oportunos. Objetivos. Sintetizar las recomendaciones incluidas en las Directrices de práctica clínica basadas en la evidencia para el seguimiento de recién nacidos en riesgo, publicada por la Centro Latinoamericano de Perinatología/Salud de la Mujer y Reproductiva de la Organización Panamericana de la Salud en el 2020, con el fin de presentar las estrategias para el seguimiento de los niños recién nacidos con condiciones de riesgo desde su nacimiento hasta los 2 años. Métodos. Se llevó a cabo una síntesis de la guía y sus recomendaciones. Además, se realizó una búsqueda sistemática en Pubmed, Lilacs, Health Systems Evidence, Epistemonikos y literatura gris de estudios desarrollados en la Región de las Américas, con el fin de identificar barreras, facilitadores y estrategias de implementación. Resultados. Se formularon 21 recomendaciones y 14 puntos de buena práctica que aplican a los recién nacidos con condiciones de riesgo hasta los dos años (prematuros y aquellos con alteraciones adquiridas o congénitas). Se identificaron barreras como la disponibilidad de pruebas de tamización, deficiencias en el sistema de referencia y conocimiento de las recomendaciones para su implementación. Conclusiones. La guía brinda recomendaciones sobre los criterios de egreso, incluidas pruebas de tamizaje; información y apoyo para padres y cuidadores; tamizaje y frecuencia de seguimiento de los niños en riesgo hasta los dos años en la Región de las Américas.

Abstract
Background/Objective: To examine maternal physical and mental health-related quality of life (HRQoL) and depression after early and late preterm and term births in the early postpartum period. Method: In a prospective pilot study, three groups of women whose newborns had to be treated in the neonatal ward during the immediate postpartum period were established and compared with each other: 20 women with extremely to very preterm birth, 20 with moderate to late preterm birth and 20 women with term birth. All participants completed the Short Form-12 Health Survey (SF-12) to measure HRQoL, and the Edinburgh Postnatal Depression Scale (EPDS) to detect depressive symptoms combined with independently developed questions to evaluate anxiety and psychological distress. Results: Maternal psychological HRQoL was significantly worse in the very preterm birth group compared to moderate to late preterm birth (p < 0.001) and full-term birth groups (p = 0.004). There were no differences between the birth groups in depressive symptoms (p = 0.083), anxiety (p = 0.238), perceived stress (p = 0.340) and the general psychological distress values (p = 0.755). In the EPDS, the depression screening instrument 30 to 65% were beyond the cut-off-value to detect major depression. Conclusions: During the early postpartum period, an extensive medical care focussing on acute stress, HRQoL parameters and depression may be a good step to improving maternal well-being.

BMC Med Imaging 2022; 22:2. [PMID: 34983431 PMCID: PMC8725479 DOI: 10.1186/s12880-021-00731-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 12/30/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To develop a non-invasive method for the prenatal prediction of neonatal respiratory morbidity (NRM) by a novel radiomics method based on imbalanced few-shot fetal lung ultrasound images. METHODS A total of 210 fetal lung ultrasound images were enrolled in this study, including 159 normal newborns and 51 NRM newborns. Fetal lungs were delineated as the region of interest (ROI), where radiomics features were designed and extracted. Integrating radiomics features selected and two clinical features, including gestational age and gestational diabetes mellitus, the prediction model was developed and evaluated. The modelling methods used were data augmentation, cost-sensitive learning, and ensemble learning. Furthermore, two methods, which embed data balancing into ensemble learning, were employed to address the problems of imbalance and few-shot simultaneously. RESULTS Our model achieved sensitivity values of 0.82, specificity values of 0.84, balanced accuracy values of 0.83 and area under the curve values of 0.87 in the test set. The radiomics features extracted from the ROIs at different locations within the lung region achieved similar classification performance outcomes. CONCLUSION The feature set we designed can efficiently and robustly describe fetal lungs for NRM prediction. RUSBoost shows excellent performance compared to state-of-the-art classifiers on the imbalanced few-shot dataset. The diagnostic efficacy of the model we developed is similar to that of several previous reports of amniocentesis and can serve as a non-invasive, precise evaluation tool for NRM prediction.

Front Pediatr 2022; 10:915846. [PMID: 36210952 PMCID: PMC9532745 DOI: 10.3389/fped.2022.915846] [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: 04/08/2022] [Accepted: 08/16/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Preterm birth is the main cause of neonatal deaths with increasing mortality and morbidity rates with decreasing GA at time of birth. Currently, premature infants are treated in neonatal intensive care units to support further development. However, the organs of, especially, extremely premature infants (born before 28 weeks of GA) are not mature enough to function optimally outside the womb. This is seen as the main cause of the high morbidity and mortality rates in this group. A liquid-filled incubator, a so-called PLS system, could potentially improve these numbers for extremely premature infants, since this system is designed to mimic the environment of the natural womb. To support the development and implementation of such a complex system and to interpret vital signals of the fetus during a PLS system operation, a digital twin is proposed. This mathematical model is connected with a manikin representing the digital and physical twin of the real-life PLS system. Before developing a digital twin of a fetus in a PLS system, its functional and technical requirements are defined and existing mathematical models are evaluated. METHOD AND RESULTS This review summarizes existing 0D and 1D fetal circulatory models that potentially could be (partly) adopted for integration in a digital twin of a fetus in a PLS system based on predefined requirements. The 0D models typically describe hemodynamics and/or oxygen transport during specific events, such as the transition from fetus to neonate. Furthermore, these models can be used to find hemodynamic differences between healthy and pathological physiological states. Rather than giving a global description of an entire cardiovascular system, some studies focus on specific organs or vessels. In order to analyze pressure and flow wave profiles in the cardiovascular system, transmission line or 1D models are used. As for now, these models do not include oxygen transport. CONCLUSION This study shows that none of the models identified in literature meet all the requirements relevant for a digital twin of a fetus in a PLS system. Nevertheless, it does show the potential to develop this digital twin by integrating (parts) of models into a single model.

Abstract
BACKGROUND Prenatal exposure to opioids (PEO) is a worldwide public health issue. Opioids cross the placental barrier and may affect the developing foetus and the birth outcomes. OBJECTIVES This review aimed to explore newborns' weight, length and head circumference, preterm birth, and perinatal death as primary outcomes in relation to PEO. The secondary outcomes were gestational age at birth, Apgar scores and length of hospitalisation after delivery. DATA SOURCES PubMed, Embase, PsycInfo and the Web of Science. STUDY SELECTION AND DATA EXTRACTION Inclusion criteria were (i) cohort, case-control or cross-sectional peer-reviewed studies published in English through 1 March 2021; (ii) comparing outcomes between prenatal exposed and unexposed groups to opioids (prescribed or obtained illegally). Exclusion criteria were foetal alcohol syndrome and non-opioid primary exposure. SYNTHESIS Data were extracted by two authors. The Newcastle-Ottawa Quality Assessment Scale was used for study quality assessment. Due to heterogeneity across studies, we used random effects models to obtain pooled standardised mean difference (SMD), pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS Data from 80 studies were extracted. In meta-analyses, opioid-exposed neonates had lower birthweight (SMD -0.77, 95% CI -0.90, -0.64, I2 = 82%), smaller head circumference (SMD -0.67, 95% CI -0.86, -0.48, I2 = 84%), shorter birth length (SMD -0.97, 95% CI -1.24, -0.70, I2 = 91%) and gestational age (SMD -0.45, 95% CI -0.60, -0.30, I2 = 80%) than unexposed neonates. Pooled risks of neonatal death and preterm birth were higher among opioid-exposed compared to unexposed neonates (RR 4.05, 95% CI 2.12, 7.72, I2 = 73%; and RR 1.92, 95% CI 1.57, 2.35, I2 = 99%). CONCLUSIONS We found increased risks of adverse birth outcomes in relation to PEO. Caution should be used in interpreting the findings, as many studies were rated as poor quality, and with substantial inter-study heterogeneity. Future studies should ensure comparability of opioid-exposed and -unexposed group to strengthen internal validity.

Abstract
BACKGROUND Infants who are born at 34°/7 to 366/7 weeks of gestation (late preterm) are at greater risk for respiratory and other neonatal morbidities. The objective of this study was to examine the effects of the administration of antenatal corticosteroids (ACS) to women at risk for late preterm delivery on the incidence of neonatal outcomes. METHOD This was a prospective cohort study of singleton gestations at risk of imminent delivery between 34°/7 and 366/7 weeks. Neonatal outcomes were compared between mothers who received ACS and those who did not. The primary outcome was the rate of composite respiratory morbidity defined as the need for treatment within 72 h of life (continuous positive airway pressure or high flow nasal cannula for least 2 h or supplemental oxygen with a fraction of inspired oxygen of at least 0.30 for at least four continuous hours or mechanical ventilation). RESULTS During the 3-year study period, 595 subjects were included in this study, comprising 234 subjects that received ACS and 361 that did not. Administration of ACS significantly reduced the rates of composite respiratory morbidity (aOR 0.63 95% CI 0.40-0.99), the use of CPAP or HFNC for at least 2 h (aOR 0.57 95% CI 0.35-0.94), and transient tachypnea of the newborn (aOR 0.48 95% CI 0.28-0.82). Neonatal hypoglycemia was more significantly increased in the ACS group compared with controls (aOR 1.64 95% CI 1.04-2.59). We found no significant between-group differences in the rate of respiratory distress syndrome, surfactant use, need for resuscitation, jaundice requiring phototherapy, admission to neonatal intensive care or special care nursery, and duration of hospitalization. CONCLUSION Administration of ACS during the late preterm period decreased neonatal respiratory complications, however, increased the rate of hypoglycemia.

Abstract
BACKGROUND Although risk factors of preterm deliveries across the world have been extensively studied, the trends and risk factors of preterm deliveries for the population of rural India, and specifically tribal women, remain unexplored. OBJECTIVE The aim of this study was to assess and compare the preterm delivery rates among women from a rural area in Gujarat, India, based on socioeconomic and clinical factors. The second aim of the study was to assess and identify predictors or risk factors for preterm deliveries. STUDY DESIGN This was a retrospective medical record review study investigating deliveries that took place at the Kasturba Maternity Hospital in Jhagadia, Gujarat, from January 2012 to June 2019 (N=32,557). We performed odds ratio and adjusted odds ratio analyses of preterm delivery risk factors. Lastly, we also considered the neonatal outcomes of preterm deliveries, both overall and comparing tribal and nontribal mothers. RESULTS For the study period, the tribal preterm delivery rate was 19.7% and the nontribal preterm delivery rate was 13.9%; the rate remained consistent for both groups over the 7-year study period. Adjusted odds ratios indicated that tribal status (adjusted odds ratio, 1.16; 95% confidence interval, 1.08–1.24), maternal illiteracy ((adjusted odds ratio, 1.29, 95% confidence interval, 1.18–1.42), paternal illiteracy (adjusted odds ratio, 1.27; 95% confidence interval, 1.15–1.410), hemoglobin <10 g/dL (adjusted odds ratio, 1.41; 95% confidence interval, 1.32–1.51), and a lack of antenatal care (adjusted odds ratio, 2.15; 95% confidence interval, 1.94–2.37) are significantly associated with higher odds of preterm delivery. The overall stillbirth rate among tribal women was 3.06% and 1.73% among nontribal women; among preterm deliveries, tribal women have a higher proportion of stillbirth outcomes (11.77%) than nontribal women (8.86%). CONCLUSION Consistent with existing literature, risk factors for preterm deliveries in rural India include clinical factors such as a lack of antenatal care and low hemoglobin. In addition, sociodemographic factors, such as tribal status, are independently associated with higher odds of delivering preterm. The higher rates of preterm deliveries among tribal women need to be studied further to detail the underlying reasons of how it can influence a woman's delivery outcome.

Abstract
Intrauterine Growth Restriction (IUGR) is a leading cause of perinatal death with no effective cure, affecting 5-10% pregnancies globally. Suppressed pro-inflammatory Th1/Th17 immunity is necessary for pregnancy success. However, in IUGR, the inflammatory response is enhanced and there is a limited understanding of the mechanisms that lead to this abnormality. Regulation of maternal T-cells during pregnancy is driven by Nuclear Factor Kappa B p65 (NF-κB p65), and we have previously shown that p65 degradation in maternal T-cells is induced by Fas activation. Placental exosomes expressing Fas ligand (FasL) have an immunomodulatory function during pregnancy. The aim of this study is to investigate the mechanism and source of NF-κB regulation required for successful pregnancy, and whether this is abrogated in IUGR. Using flow cytometry, we demonstrate that p65+ Th1/Th17 cells are reduced during normal pregnancy, but not during IUGR, and this phenotype is enforced when non-pregnant T-cells are cultured with normal maternal plasma. We also show that isolated exosomes from IUGR plasma have decreased FasL expression and are reduced in number compared to exosomes from normal pregnancies. In this study, we highlight a potential role for FasL+ exosomes to regulate NF-κB p65 in T-cells during pregnancy, and provide the first evidence that decreased exosome production may contribute to the dysregulation of p65 and inflammation underlying IUGR pathogenesis.

Abstract
BACKGROUND In utero closure of meningomyelocele using an open hysterotomy approach is associated with preterm delivery and adverse neonatal outcomes. OBJECTIVE This study compared the neonatal outcomes in in utero meningomyelocele closure using a 2-port, exteriorized uterus, fetoscopic approach vs the conventional open hysterotomy approach. STUDY DESIGN This retrospective cohort study included all consecutive patients who underwent in utero meningomyelocele closure using open hysterotomy (n=44) or a 2-port, exteriorized uterus, fetoscopic approach (n=46) at a single institution between 2012 and 2020. The 2-port, exteriorized uterus, fetoscopic closure was composed of the following 3 layers: a bovine collagen patch, a myofascial layer, and a skin. The frequency of respiratory distress syndrome and a composite of other adverse neonatal outcomes, including retinopathy of prematurity, periventricular leukomalacia, and perinatal death, were compared between the study groups. Regression analyses were performed to determine any association between the fetoscopic closure and adverse neonatal outcomes, adjusted for several confounders, including gestational age of <37 weeks at delivery. RESULTS The fetoscopic closure was associated with a lower rate of respiratory distress syndrome than the open hysterotomy closure (11.5% [5 of 45] vs 29.5% [13 of 44]; P=.037). The proportion of neonates with a composite of other adverse neonatal outcomes in the fetoscopic group was half of that observed patients in the open hysterotomy group; however, this difference did not reach statistical significance (4.3% [2 of 46] vs 9.1% [4 of 44]; P=.429). Here, regression analysis has demonstrated that fetoscopic meningomyelocele closure was associated with a lower risk of respiratory distress syndrome (adjusted odds ratio, 0.23; 95% confidence interval, 0.06-0.84; P=.026) than open hysterotomy closure. CONCLUSION In utero meningomyelocele closure using a 2-port, exteriorized uterus, fetoscopic approach was associated with a lower risk of respiratory distress syndrome than the conventional open hysterotomy meningomyelocele closure.

Abstract
BACKGROUND Preterm birth (<37 weeks), low birth weight (LBW,<2500g), and small for gestational age (SGA,<10th centile of birth weight for gestational age and sex) are markers of newborn vulnerability with a high risk of mortality. We estimated the prevalence of phenotypes combining these three markers and quantified the mortality risk associated with them. METHODS Population-based cohort study using routine register-based linked data on all births and deaths in Brazil from January 1, 2011, to December 31, 2018. We estimated the prevalence of preterm, LBW, and SGA individually and for phenotypes combining these characteristics. The mortality risk associated with each phenotype: early neonatal, late neonatal, neonatal, post-neonatal, infant, 1-4 years, and under five years was quantified using mortality rates and hazard ratios (HRs) with 95% confidence interval (CI) were estimated using Cox proportional hazard models. FINDINGS 17,646,115 live births were included. Prevalence of preterm birth, LBW and SGA were 9.4%, 9.6% and 9.2%, respectively. Neonatal mortality risk was 16-fold (HR=15.9; 95% CI:15.7-16.1) higher for preterm compared to term, 3 times higher (HR=3.4; (95% CI:3.3-3.4) for SGA compared to adequate for gestational age (AGA), and >25 times higher for LBW (HR=25.8; (95% CI:25.5-26.1) compared to normal birth weight (NBW). 18% of all live births were included in one of the small vulnerable newborn phenotypes. Of those 8.2% were term-SGA (4.7%NBW, 3.5%LBW), 0.6% were term-AGA-LBW, 8.3% preterm-AGA (3.8%NBW, 4.5%LBW) and 1.0% preterm-SGA-LBW. Compared to term-AGA-NBW, the highest mortality risk was for preterm-LBW phenotypes (HR=36.2(95%CI 35.6-36.8) preterm-AGA-LBW, HR=62.0(95%CI 60.8-63.2) preterm-SGA-LBW). The increased mortality risk associated with vulnerable newborn phenotypes was highest in the first month of life, with attenuated but continued high risk in the post-neonatal period and 1-4 years of age. INTERPRETATION Our findings support the value of using more detailed phenotypes to identify those at highest risk. More granular data can inform care at the individual level, advance research, especially for prevention, and accelerate progress towards global targets such as the Sustainable Development Goals.

Abstract
BACKGROUND Given the unpredictable nature of preterm birth and the short-term impact of antenatal corticosteroids on neonatal outcomes, optimal timing of antenatal corticosteroid administration (2–7 days from expected birth) remains challenging. OBJECTIVE We set out to evaluate the likelihood of delivery between 2 and 7 days after antenatal corticosteroid administration in the late preterm period and whether this differs based on the indication for corticosteroid administration. STUDY DESIGN Retrospective cohort of all singletons that received antenatal corticosteroids in the late preterm period (34 0/7 to 36 6/7 weeks’ gestation) and delivered within a large health system between November 2017 and March 2020. Women who received antenatal corticosteroids before the late preterm period, major fetal structural malformations, and cases with missing data were excluded. Cases were stratified on the basis of the indication for antenatal corticosteroid administration, that is, anticipated spontaneous late preterm birth or medically indicated late preterm birth. The primary outcome was delivery between 2 and 7 days after the administration of the first dose of antenatal corticosteroids. Secondary outcomes included time interval from antenatal corticosteroid administration to delivery and delivery during the first 2 days or later than 7 days after antenatal corticosteroid administration. Multivariable logistic regression was performed to evaluate factors associated with optimal timing while adjusting for potential confounders. RESULTS Of the 1238 patients included in the study, 656 (53%) delivered within the first day after antenatal corticosteroid administration and thus received only the first of 2 doses. Regardless of the indication for late preterm antenatal corticosteroid administration, the likelihood of delivery between 2 and 7 days later was 13.3% (165 of 1238). Moreover, it was more common (23.4% vs 5.0%; P≤.001) (Table 2) and more likely (adjusted odds ratio, 5.88; 95% confidence interval, 4.00–9.09) in women at risk of medically indicated preterm birth than in those with anticipated spontaneous preterm birth. Furthermore, women with anticipated spontaneous preterm birth had a shorter time interval from antenatal corticosteroid administration to delivery (10.7 vs 49.71 hour; P≤.001). CONCLUSION Regardless of the indication for late preterm antenatal corticosteroid administration, the likelihood of delivery between 2 and 7 days later was low. Nevertheless, our data suggested that delivery within the desired time interval of antenatal corticosteroid administration is more common in women at risk of medically indicated late preterm birth compared with those at risk of spontaneous late preterm birth.
