Abstract
Low Apgar scores and low umbilical arterial (UA) blood pH are considered indicators of adverse perinatal events. This study investigated trends of these perinatal health indicators in Germany. Perinatal data on 10,696,831 in-hospital live births from 2008 to 2022 were obtained from quality assurance institutes. Joinpoint regression analysis was used to quantify trends of low Apgar score and UA pH. Additional analyses stratified by mode of delivery were performed on term singletons with cephalic presentation. Robustness against unmeasured confounding was analyzed using the E-value sensitivity analysis. The overall rates of 5-min Apgar scores < 7 and UA pH < 7.10 in liveborn infants were 1.17% and 1.98%, respectively. For low Apgar scores, joinpoint analysis revealed an increase from 2008 to 2011 (annual percent change (APC) 5.19; 95% CI 3.66-9.00) followed by a slower increase from 2011 to 2019 (APC 2.56; 95% CI 2.00-3.03) and a stabilization from 2019 onwards (APC - 0.64; 95% CI - 3.60 to 0.62). The rate of UA blood pH < 7.10 increased significantly between 2011 and 2017 (APC 5.90; 95% CI 5.15-7.42). For term singletons in cephalic presentation, the risk amplification of low Apgar scores was highest after instrumental delivery (risk ratio 1.623, 95% CI 1.509-1.745), whereas those born spontaneous had the highest increase in pH < 7.10 (risk ratio 1.648, 95% CI 1.615-1.682). Conclusion: Rates of low 5-min Apgar scores and UA pH in liveborn infants increased from 2008 to 2022 in Germany. What is Known: • Low Apgar scores at 5 min after birth and umbilical arterial blood pH are associated with adverse perinatal outcomes. • Prospective collection of Apgar scores and arterial blood pH data allows for nationwide quality assurance. What is New: • The rates of liveborn infants with 5-min Apgar scores < 7 rose from 0.97 to 1.30% and that of umbilical arterial blood pH < 7.10 from 1.55 to 2.30% between 2008-2010 and 2020-2022. • In spontaneously born term singletons in cephalic presentation, the rate of metabolic acidosis with pH < 7.10 and BE < -5 mmol/L in umbilical arterial blood roughly doubled between the periods 2008-2010 and 2020-2022.

Abstract
BACKGROUND Over 95% of infants less than 32 weeks gestational age-very preterm infants (VPTI)-require cardiorespiratory support at birth. Clinical condition at birth is assessed by the Apgar score, but the precision and accuracy of activity and grimace has not been evaluated. We hypothesised activity and grimace could predict the level of cardiorespiratory support required for stabilisation. METHODS Two hundred twenty-nine videos of VPTI resuscitations at Monash Children's Hospital and The Royal Women's Hospital, Melbourne were evaluated, with 78 videos eligible for assessment. Activity and grimace were scored (0, 1, or 2) by seven consultant neonatologists, with inter-rater reliability assessed. Activity and grimace were correlated with the maximum level of cardiorespiratory support required for stabilisation. RESULTS Kendall's Coefficient of Concordance (W) showed strong interobserver agreement for activity (W = 0.644, p < 0.001) and grimace (W = 0.722, p < 0.001). Neither activity nor grimace independently predicted the level of cardiorespiratory support required. Combining activity and grimace showed non-vigorous infants (combined score <2) received more cardiorespiratory support than vigorous (combined score ≥ 2). CONCLUSION Scoring of activity and grimace was consistent between clinicians. Independently, activity and grimace did not correlate with perinatal stabilisation. Combined scoring showed non-vigorous infants had greater resuscitation requirements. IMPACT Our study evaluates the precision and accuracy of activity and grimace to predict perinatal stability, which has not been validated in infants <32 weeks gestational age. We found strong score agreement between assessors, indicating video review is a practical and precise method for grading of activity and grimace. Combined scoring to allow a dichotomous evaluation of infants as non-vigorous or vigorous showed the former group required greater cardiorespiratory support at birth.

Abstract
AIM To examine potential correlations between cardiac output (CO) with cerebral-regional-oxygen-saturation (crSO2 ) and cerebral-fractional-tissue-oxygen-extraction (cFTOE) during immediate foetal-to-neonatal transition in term and preterm neonates with and without respiratory support. METHODS Post hoc analyses of secondary outcome parameters of prospective observational studies were performed. We included neonates with cerebral near-infrared-spectroscopy (NIRS) monitoring and an oscillometric blood pressure measurement at minute 15 after birth. Heart rate (HR) and arterial oxygen saturation (SpO2 ) were monitored. CO was calculated with Liljestrand and Zander formula and correlated with crSO2 and cFTOE. RESULTS Seventy-nine preterm neonates and 207 term neonates with NIRS measurements and calculated CO were included. In 59 preterm neonates (mean gestational age (GA): 29.4 ± 3.7 weeks) with respiratory support, CO correlated significantly positively with crSO2 and significantly negatively with cFTOE. In 20 preterm neonates (GA 34.9 ± 1.3 weeks) without respiratory support and in 207 term neonates with and without respiratory support, CO correlated neither with crSO2 nor with cFTOE. CONCLUSION In compromised preterm neonates with lower gestational age and in need of respiratory support, CO was associated with crSO2 and cFTOE, whereas in stable preterm neonates with higher gestational age as well as in term neonates with and without respiratory support, no associations were observed.

Abstract
OBJECTIVES The objective of this study was to compare the maximum 5-min Apgar score of 10 among different U.S. races and Hispanic ethnicity. METHODS Retrospective population-based cohort study from the National Center for Health Statistics (NCHS), and Division of Vital Statistics natality online database. We included only deliveries where the race and Hispanic ethnicity of the father and mother were listed as either Black, White, Chinese, or Asian Indian and as Hispanic or Latino origin or other. Proportions of 5-Minute Apgar scores of 10 were compared among different races and Hispanic ethnicity for six groups each for mother and father: Non-Hispanic or Latino White, Hispanic or Latino White, Non-Hispanic or Latino Black, Hispanic or Latino Black, Chinese, and Asian Indian. RESULTS The study population consists of 9,710,066 mothers and 8,138,475 fathers from the US natality birth data 2016-2019. Black newborns had a less than 50% chance of having a 5-min Apgar score of 10 when compared to white newborns (OR 0.47 for Black mother and Black father; p<0.001). White babies (non-Hispanic and Hispanic) had the highest proportion of Apgar scores of 10 across all races and ethnicities. CONCLUSIONS The Apgar score introduces a bias by systematically lowering the score in people of color. Embedding skin color scoring into basic data and decisions of health care propagates race-based medicine. By removing the skin color portion of the Apgar score and with it's racial and ethnic bias, we will provide more accuracy and equity when evaluating newborn babies worldwide.

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.

Abstract
Background Birth asphyxia is one of the leading causes of neonatal mortality worldwide. In Uganda, it accounts for 28.9% of all neonatal deaths. With a view to inform policy and practice interventions to reduce adverse neonatal outcomes, we aimed to determine the prevalence and factors associated with birth asphyxia at two referral hospitals in Northern Uganda. Methods This was a cross-sectional study, involving women who gave birth at two referral hospitals. Women in labour were consecutively enrolled by the research assistants, who also attended the births and determined Apgar scores. Data on socio-demographic characteristics, pregnancy history and care during labour, were obtained using a structured questionnaire. Participants were tested for; i) malaria (peripheral and placental blood samples), ii) syphilis, iii) white blood cell counts (WBC), and iv) haemoglobin levels. The prevalence of birth asphyxia was determined as the number of newborns with Apgar scores < 7 at 5 min out of the total population of study participants. Factors independently associated with birth asphyxia were determined using multivariable logistic regression analysis and a p-value < 0.05 was considered statistically significant. Results A total of 2,930 mother-newborn pairs were included, and the prevalence of birth asphyxia was 154 [5.3% (95% confidence interval: 4.5- 6.1)]. Factors associated with birth asphyxia were; maternal age ≤ 19 years [adjusted odds ratio (aOR) 1.92 (1.27–2.91)], syphilis infection [aOR 2.45(1.08–5.57)], and a high white blood cell count [aOR 2.26 (1.26–4.06)], while employment [aOR 0.43 (0.22–0.83)] was protective. Additionally, referral [aOR1.75 (1.10–2.79)], induction/augmentation of labour [aOR 2.70 (1.62–4.50)], prolonged labour [aOR 1.88 (1.25–2.83)], obstructed labour [aOR 3.40 (1.70–6.83)], malpresentation/ malposition [aOR 3.00 (1.44–6.27)] and assisted vaginal delivery [aOR 5.54 (2.30–13.30)] were associated with birth asphyxia. Male newborns [aOR 1.92 (1.28–2.88)] and those with a low birth weight [aOR 2.20 (1.07–4.50)], were also more likely to develop birth asphyxia. Conclusion The prevalence of birth asphyxia was 5.3%. In addition to the known intrapartum complications, teenage motherhood, syphilis and a raised white blood cell count were associated with birth asphyxia. This indicates that for sustained reduction of birth asphyxia, appropriate management of maternal infections and improved intrapartum quality of care are essential.

Abstract
BACKGROUND Many children born very low birth weight (VLBW) experience school struggles with preparedness requiring adequate physical, social, behavioural, cognitive and communication skills. A global assessment of proficiency is necessary to identify those at risk in any such area and direct early intervention accordingly. Study objectives were to characterize developmental vulnerability and school readiness scores in these key domains in a sample of children born VLBW versus their provincial public school system peers and identify early-life infant and parent factors related to suboptimal school readiness. METHODS The Early Development Instrument teacher assessments of school readiness were collected for a Canadian VLBW sample (NCT02759809). Comparisons between children born VLBW and peers were made. Group differences between children born VLBW considered vulnerable (<10th percentile, not developmentally ready for learning) and not vulnerable were tested and linear regression explored associations between early-life factors and domain scores. RESULTS Of 77 available Early Development Instrument assessments, median (interquartile range) assessment age was 6.0 (5.7, 6.2) years, birth weight 950 (793, 1250) grammes and birth gestation 27.4 (25.6, 29.7) weeks. A higher proportion of children born VLBW versus peers exhibited vulnerability in Physical Health and Well-being (24.7% vs. 16.1%, p = 0.04), Communication Skills and General Knowledge (23.4% vs. 10.2%, p = 0.0001) and vulnerability in ≥2 domains (26.0% vs. 14.4%, p = 0.004). Children born VLBW classified as vulnerable versus not vulnerable had lower birth gestation and 5-min Apgar. Adjusted regression models found Apgar <7 associated with lower scores for Physical Health and Well-being (-0.86; 95%CI: -1.71, -0.00; p = 0.049), Social Competence (-1.77; 95%CI: -2.92, -0.62; p = 0.003), Emotional Maturity (-1.55; 95%CI: -2.43, -0.66; p = 0.0009) and Communication Skills and General Knowledge (-1.63; 95%CI: -3.19, -0.06; p = 0.04). CONCLUSIONS This VLBW sample exhibited poor school readiness in multiple domains. Identification of lower birth gestation and Apgar may assist targeted early interventions to mitigate vulnerability.

Abstract
BACKGROUND Apgar scores measure newborn health and are strongly associated with infant outcomes, but their performance has largely been determined in primarily white populations. Given the majority of the global population is not white, we aim to assess whether the association between low Apgar score and mortality in infants varies across racial groups. METHODS AND FINDINGS Population-based cohort study using 2016 to 2017 United States National Vital Statistics System data. The study included singleton infants born between 37+0 and 44+6 weeks to mothers over 15 years, without congenital abnormalities. We looked at 3 different mortality outcomes: (1) early neonatal mortality; (2) overall neonatal mortality; and (3) infant mortality. We used logistic regression to assess the association between Apgar score (categorized as low, intermediate, and normal) and each mortality outcome, and adjusted for gestational age, sex, maternal BMI, education, age, previous number of live births, and smoking status, and stratified these models by maternal race group (as self-reported on birth certificates). The cohort consisted of 6,809,653 infants (52.8% non-Hispanic white, 23.7% Hispanic, 13.8% non-Hispanic black, 6.6% non-Hispanic Asian, and 3.1% non-Hispanic other). A total of 6,728,829 (98.8%) infants had normal scores, 63,467 (0.9%) had intermediate scores, and 17,357 (0.3%) had low Apgar scores. Compared to infants with normal scores, low-scoring infants had increased odds of infant mortality. There was strong evidence that this association varied by race (p < 0.001) with adjusted odds ratios (AORs) of 54.4 (95% confidence interval [CI] 49.9 to 59.4) in non-Hispanic white, 70.02 (95% CI 60.8 to 80.7) in Hispanic, 23.3 (95% CI 20.3 to 26.8) in non-Hispanic black, 100.4 (95% CI 74.5 to 135.4) in non-Hispanic Asian, and 26.8 (95% CI 19.8 to 36.3) in non-Hispanic other infants. The main limitation was missing data for some variables, due to using routinely collected data. CONCLUSIONS The association between Apgar scores and mortality varies across racial groups. Low Apgar scores are associated with mortality across racial groups captured by United States (US) records, but are worse at discriminating infants at risk of mortality for black and non-Hispanic non-Asian infants than for white infants. Apgar scores are useful clinical indicators and epidemiological tools; caution is required regarding racial differences in their applicability.

Abstract
Aim To assess the strength of associations between interrelated perinatal risk factors and mortality in very preterm infants. Methods Information on all live‐born infants delivered in Sweden at 22–31 weeks of gestational age (GA) from 2011 to 2019 was gathered from the Swedish Neonatal Quality Register, excluding infants with major malformations or not resuscitated because of anticipated poor prognosis. Twenty‐seven perinatal risk factors available at birth were exposures and in‐hospital mortality outcome. Orthogonal partial least squares discriminant analysis was applied to assess proximity between individual risk factors and mortality, and receiver operating characteristic (ROC) curves were used to estimate discriminant ability. Results In total, 638 of 8,396 (7.6%) infants died. Thirteen risk factors discriminated reduced mortality; the most important were higher Apgar scores at 5 and 10 min, GA and birthweight. Restricting the analysis to preterm infants <28 weeks’ GA (n = 2939, 16.9% mortality) added antenatal corticosteroid therapy as significantly associated with lower mortality. The area under the ROC curve (the C‐statistic) using all risk factors was 0.86, as determined after both internal and external validation. Conclusion Apgar scores, gestational age and birthweight show stronger associations with mortality in very preterm infants than several other perinatal risk factors available at birth.

Abstract
Background and Objectives: Vasopressors are used for treating maternal hypotension. However, the appropriate administration method and effects on newborns have not been reported. We evaluated maternal blood pressure fluctuation and neonatal findings in patients who received continuous vasopressor administration during elective cesarean sections and those who received bolus vasopressor administration upon onset of hypotension. Materials and Methods: We retrospectively analyzed the data of 220 patients scheduled for elective cesarean delivery under spinal anesthesia at Mie University Hospital between April 2017 and March 2021. The patients were classified according to the method of vasopressor administration. Maternal information, intraoperative maternal blood pressure fluctuation, and neonatal findings were examined. A multiple regression analysis was performed for the administration of postpartum neonatal respiratory support using maternal background information and other variables related to blood pressure changes as independent variables. Results: The Continuous group and the Bolus group were composed of 98 and 122 patients, respectively. No difference was observed in maternal background information between the groups. Significant changes were noted in several blood pressure parameters between both groups. As for neonatal parameters, newborns of Bolus group patients had lower pO2, 1 min and 5 min Apgar scores, and required more respiratory support than those of Continuous group patients. In the multiple regression analysis, the groups and maternal post-anesthesia diastolic blood pressure variability were considered explanatory variables. Conclusions: Maternal hypotension and the need for neonatal respiratory support associated with anesthesia administration in elective cesarean section may be improved by continuous vasopressor administration upon induction of combined spinal–epidural anesthesia.

Abstract
UNLABELLED Functional gastrointestinal disorders (FGIDs) are common in early childhood. It has been demonstrated that neonatal acidemia at delivery can lead to significant neonatal morbidity. The primary aim of this study was to evaluate the relationship between acidemia at birth and the development of FGIDs, as regurgitation, colic, and constipation, in term infants. Term newborns born at the Foggia University Hospital, Italy during the year 2020 were included in the study. As per routine clinical practice, a cord blood gas analysis on a blood sample drawn from the umbilical artery (UA) of each infant immediately after birth was performed, and Apgar score was recorded. One year after birth, each infant's parents were interviewed through a phone call to investigate development of FGIDs, feeding practices, and morbidities. During the study period, 1574 term newborns met the inclusion criteria. The prevalence of infantile colic, regurgitation, and constipation was higher in infants with low UA pH (colic 51.5% vs. 25.4%, p < 0.001; regurgitation 30.6% vs. 15.2%, p < 0.001; constipation 24.6% vs. 16.0%, p = 0.015), with infants having moderate-severe acidemia facing the highest risk for all the examined FGIDs. In binary logistic regression analyses, UA pH and perinatal antibiotic exposure proved to be independently associated with the later diagnosis of each FGID. CONCLUSION Newborns with acidemia at birth appear to face a higher risk of FGIDs in infancy. Avoiding low cord blood pH should continue to be the goal for obstetricians, while enhanced long-term surveillance for infants who experienced birth acidemia should be required. WHAT IS KNOWN • Cord blood gas analysis is recommended in all high-risk deliveries, and in some centers, it is performed after all deliveries. • Neonatal acidemia at birth has been linked to adverse outcomes, mainly neurological. Recently, perinatal asphyxia has been reported to increase the risk of developing necrotizing enterocolitis in term infants. WHAT IS NEW • An association between acidemia at birth and risk of developing FGIDs such as regurgitation and colic during the first year of life had never been described so far. • An increased surveillance of infants with low UA pH at birth may be beneficial and could allow for early detection of any of the reported FGIDs.

Abstract
Assessment of an infant's condition in the delivery room represents a prerequisite to adequately initiate medical support. In her seminal paper, Virginia Apgar described five parameters to be used for such an assessment. However, since that time maternal and neonatal care has changed; interventions were improved and infants are even more premature. Nevertheless, the Apgar score is assigned to infants worldwide but there are concerns about low interobserver reliability, especially in preterm infants. Also, resuscitative interventions may preclude the interpretation of the score, which is of concern when used as an outcome parameter in delivery room intervention studies. Within the context of these changes, we performed a critical appraisal on how to assess postnatal condition of the newborn including the clinical parameters of the Apgar score, as well as selected additional parameters and a proposed new scoring system. The development of a new scoring system that guide clinicians in assessing infants and help to decide how to support postnatal adaptation is discussed. IMPACT: This critical paper discusses the reliability of the Apgar score, as well as additional parameters, in order to improve assessment of a newborn's postnatal condition. A revised neonatal scoring system should account for infant maturity and the interventions administered. Delivery room assessment should be directed toward determining how much medical support is needed and how the infant responds to these interventions.

Abstract
Background: Pre-term births are associated with increased risk of various morbidities, especially neurological. Early detection and early intervention to prevent these morbidities will have immediate and long-term benefits to the individuals and society at large. However, the screening and assessment tools, including both clinical and radiological, are not uniformly available in resource-poor settings. The present study was carried out to evaluate the validity of the clinical screening tools for detecting neurodevelopmental delay among very-low-birth-weight (VLBW) pre-term babies. Methods: This prospective observational study was undertaken in the child development unit of a tertiary care hospital from July 2015 to October 2017. All pre-term VLBW neonates admitted in level III Neonatal Intensive Care within the first 24 hours of life were included in the study. They were subjected to Hammersmith Neonatal Neurological Examination (HNNE) and magnetic resonance imaging (MRI) of brain at term-equivalent age. Subsequently, the same group was followed up with Amiel-Tison (AT) angles, Child Development Centre (CDC) grading for sitting developed at Trivandrum, Kerala, India, and Denver Development Screening Test (DDST-II gross motor) at eight months corrected age, and their outcomes were analyzed. Results: 17.9% of the ex-preterm were abnormal as per HNNE evaluation at term-corrected age. At short-term follow-up screening, 13.8% were found to be abnormal based on AT angles, while 35.2% were found to be abnormal as per CDC grading and 30.4% were found to have risk for delay as per DDST-II (gross motor). A high level of sensitivity (93.6%) and positive predictive value (91.2%) was observed for HNNE at term equivalent with MRI brain assessment considered as gold standard. Among the follow-up screening tools, CDC grading for sitting, AT angles, and DDST-II had high sensitivity (>85%). Conclusion: The combination of HNNE along with radiological assessment at term-corrected age can be considered as appropriate for predicting long-term neurodevelopmental outcome in VLBW pre-term infants. During follow-up, simple tools like CDC grading for motor milestones, AT angles, and DDST-II may be utilized if facilities for standard assessment are not available as in resource-poor settings.

Abstract
Placental abruption (PA) is a concern for maternal and neonatal morbidity. Adverse neonatal outcomes in the setting of PA include higher risk of prematurity. Placental pathologies include maternal vascular malperfusion (MVM), fetal vascular malperfusion (FVM), acute chorioamnionitis, and villitis of unknown etiology (VUE). We aimed to investigate how placental pathology contributes to acute neonatal outcome in PA. A retrospective cohort study of all placentas with PA were identified. Exposures were MVM, FVM, acute chorioamnionitis and VUE. The primary outcome was NICU admission and the secondary outcomes included adverse base deficit and Apgar scores, need for resuscitation, and small-for-gestational age. A total of 287 placentas were identified. There were 160 (59.9%) of placentas with PA alone vs 107 (40.1%) with PA and additional placental pathologies. Odds of NICU admission were more than two times higher in pregnancies with placental pathologies (OR = 2.37, 95% CI 1.28-4.52). These estimates were in large part mediated by prematurity and birthweight, indirect effect acting through prematurity was OR 1.79 (95% CI 1.12-2.75) and through birthweight OR 2.12 (95% CI 1.40-3.18). Odds of Apgar score ≤ 5 was more than four times higher among pregnancies with placental pathologies (OR = 4.56, 95% CI 1.28-21.26). Coexisting placental pathology may impact Apgar scores in pregnancies complicated by PA. This knowledge could be used by neonatal teams to mobilize resources in anticipation of the need for neonatal resuscitation.

Abstract
A low Apgar score is associated with increased risk of cerebral palsy (CP) in term infants, while such association remains controversial in preterm neonates. The objective of this study was to assess association between 5-minute Apgar scores and CP in different subcategories of preterm birth based on gestational age. The Slovenian National Perinatal Information System was used to identify singleton children without congenital malformations live-born at 22 to 37 weeks of gestation between 2002 and 2010. Data were linked to the Slovenian Registry of Cerebral Palsy in children born between 2002 and 2010. CP was diagnosed at a minimum of 5 years of age. Of 11,924 children included, 241 (2.0%) died before discharge and 153 (1.3%) were diagnosed with CP. Five-minute Apgar scores <7 were significantly associated with higher risk of death or CP (compared with scores ≥9) at all preterm gestations. CP alone was associated with Apgar scores <7 only at moderately or late preterm gestation (32-36 weeks) (adjusted relative risk [aRR]: 8.27; 95% confidence interval [CI]: 1.87-36.64 for scores 0-4 and aRR: 4.96; 95% CI 1.89-13.06 for scores 5-6). In conclusion, a low 5-minute Apgar score was associated with combined outcome of neonatal death or CP in all preterm births, while in surviving preterm infants at >32 weeks a low 5-minute Apgar score was associated with CP.

Abstract
Background Administration of antenatal corticosteroids (ANC) for impending preterm delivery beyond 34 weeks of gestation continues to be a controversial issue despite various guidelines for obstetricians and gynaecologists. Objective To compare outcomes following exposure to ANC for infants born between 34–36+6 weeks’ gestation. Methods A systematic review of randomised controlled trials (RCT) reporting neonatal outcomes after ANC exposure between 34–36+6 weeks’ gestation using Cochrane methodology. Databases including PubMed, Embase, Emcare, Cochrane Central library and Google Scholar were searched in May 2020. Primary outcomes: (1) Need for respiratory support (Mechanical ventilation, CPAP, high flow) or oxygen (2) Hypoglycemia. Secondary outcomes included respiratory distress syndrome (RDS), transient tachypnoea of newborn (TTN), need for neonatal resuscitation at birth [only in the delivery room immediately after birth (not in neonatal intensive care unit (NICU)], admission to NICU, mortality and developmental follow up. Level of evidence (LOE) was summarised by GRADE guidelines. Main results Seven RCTs (N = 4144) with low to high risk of bias were included. Only one RCT was from high income countries, Meta-analysis (random-effects model) showed (1) reduced need for respiratory support [5 RCTs (N = 3844); RR = 0.68 (0.47–0.98), p = 0.04; I2 = 55%; LOE: Moderate] and (2) higher risk of neonatal hypoglycaemia [4 RCTs (N = 3604); RR = 1.61(1.38–1.87), p<0.00001; I2 = 0%; LOE: High] after ANC exposure. Neonates exposed to ANC had reduced need for resuscitation at birth. The incidence of RDS, TTN and surfactant therapy did not differ significantly. None of the included studies reported long-term developmental follow up. Conclusions Moderate quality evidence indicates that ANC exposure reduced need for respiratory support, and increased the risk of hypoglycaemia in late preterm neonates. Large definitive trials with adequate follow up for neurodevelopmental outcomes are required to assess benefits and risks of ANC in this population.

Abstract
Premature infants are prone to dyspnea after birth due to immature development, and some infants require respiratory assistance. However, the risk factors for respiratory assistance in premature infants are rarely reported. The present study enrolled 3,394 premature infants (665 infants had been provided with respiratory assistance and 2,729 had not used respiratory assistance) to retrospectively analyze the risk factors associated with respiratory aid. The multivariate logistic regression analysis demonstrated that placental abnormality [odds ratio (OR)=1.284; P=0.048], the male sex (OR=0.696; P=0.001), delivery via cesarean section (OR=1.538; P<0.001), low 1-min Apgar score (OR=0.727; P<0.001), low birth weight (OR=0.999; P=0.005) and low gestational age (OR=0.616; P<0.001) were independent risk factors for respiratory assistance in premature infants. Overall, a number of risk factors, including placental abnormality, cesarean section, low 1-min Apgar score, low birth weight and small gestational age, were identified for respiratory assistance in premature infants. By conducting a risk assessment of risk factors at birth and using this information to provide timely respiratory assistance, the survival rates of premature infants may increase.

Abstract
Introduction: Children with low body weight for gestational age are five times more likely to die in the neonatal period and 4.7 times more likely to die in the first years of life compared to children born at term. The aim To analyze early adaptation to extrauterine life of low body weight for gestational age. Material and methods: Retrospective study with the observation period January-September 2018. The data were obtained by reviewing the medical histories of newborns. As parameters of early adaptation, we observed the Apgar score in the 1st and 5th minute as well as the presence of polycythemia at birth. Results: Out of a total of 405 newborns, 52 had low body weight for gestational age. Apgar score in the 1st and 5th minute was statistically significantly lower in children small for gestational age compared to children with normal body weight for gestational age (p <0.05). Polycythemia is a mechanism of adaptation statistically significantly more often present in children of small body weight for gestational age (p <0.05). Conclusion: Children of low body weight for gestational age have a lower Apgar score in the first and fifth minutes as well as more frequent polycythemia compared to children with normal body weight and we can take them as good indicators of adaptation to early extrauterine life.

Abstract
BACKGROUND Gestational age is the major determinant of neonatal death (death within the first 28 days of life) in preterm infants. The joint effect of gestational age and Apgar score on the risk of neonatal death is unknown. METHODS Using data from the Swedish Medical Birth Register, we identified 113,300 preterm infants (22 weeks 0 days to 36 weeks 6 days of gestation) born from 1992 through 2016. In analyses stratified according to gestational age (22 to 24 weeks, 25 to 27 weeks, 28 to 31 weeks, 32 to 34 weeks, and 35 or 36 weeks), we estimated adjusted relative risks of neonatal death and absolute rate differences in neonatal mortality (i.e., the excess number of neonatal deaths per 100 births) according to the Apgar scores at 5 and 10 minutes and according to the change in the Apgar score between 5 minutes and 10 minutes. Scores range from 0 to 10, with higher scores indicating a better physical condition of the newborn. RESULTS There were 1986 neonatal deaths (1.8%). The incidence of neonatal death ranged from 0.2% (at 36 weeks of gestation) to 76.5% (at 22 weeks of gestation). Lower Apgar scores were associated with higher relative risks of neonatal death and greater absolute rate differences in neonatal mortality in all gestational-age strata. For example, among infants born at 28 to 31 weeks, the adjusted absolute rate differences according to the 5-minute Apgar score, with those who had a score of 9 or 10 serving as the reference group, were 51.7 (95% confidence interval [CI], 38.1 to 65.4) for a score of 0 or 1, 25.5 (95% CI, 18.3 to 32.8) for a score of 2 or 3, 7.1 (95% CI, 5.1 to 9.1) for a score of 4 to 6, and 1.2 (95% CI, 0.5 to 1.9) for a score of 7 or 8. An increase in the Apgar score between 5 minutes and 10 minutes was associated with lower neonatal mortality than a stable Apgar score. CONCLUSIONS In this study, Apgar scores at 5 and 10 minutes provided prognostic information about neonatal survival among preterm infants across gestational-age strata.

Abstract
BACKGROUND Neonatal acidaemia at birth can increase neonatal morbidity and mortality and it is predictive of neonatal asphyxia. The umbilical blood gas analysis is a valid tool for the evaluation of neonatal acidaemia. However, umbilical cord blood gas analysis is commonly performed in high-risk situations or in the setting of Apgar scores < 7 at 5 min. METHODS A retrospective cohort study was conducted from June to December 2018 at the Department of mother's and child's health, Poliambulanza Foundation Hospital Institute. Inclusion criteria were: full term newborns with body weight appropriate for gestational age, born by vaginal delivery or caesarean section, reassuring Apgar Score > 7 at 5 min, arterial cord blood gas analysis showing pH < 7.4 or BE <-8 mmol/l or lactate > 6 mmol/l. The aim was to evaluate the predictive role of blood gas analysis for respiratory distress syndrome in newborns with reassuring Apgar Score. RESULTS 352 full term newborns were enrolled. Umbilical cord blood artery pH showed an association with respiratory distress syndrome (χ2(1) = 10,084, OR (95% CI): 3,9 × 10- 4(2,9 × 10- 6 - 0,048); p < 0,05). ROC curve revealed that the cut-off point of pH was 7.12, with a sensibility and specificity of 68 and 63%, respectively. CONCLUSIONS Umbilical cord blood artery pH < 7.12 at birth is associated to respiratory distress syndrome in newborns. Blood gas analysis is an important instrument to help health care providers during assistance in the delivery room, but also to early identify newborns at high risk for respiratory distress syndrome and better manage the care of these newborns after birth.

Abstract
A literature review was carried out to identify pre and perinatal characteristics associated with variation in Apgar scores in population-based studies. The parameters identified in the literature search were included in the classical twin design study to estimate effects of pre and perinatal factors shared and nonshared by twins and to test for a contribution of genetic factors in 1- and 5-min Apgar scores in a large sample of Dutch monozygotic (MZ) and dizygotic (DZ) twins. The sample included MZ and DZ twins (N = 5181 pairs) recruited by the Netherlands Twin Register shortly after birth, with data on prenatal characteristics and Apgar scores at first and/or fifth minutes. The ordinal regression and structural equation modeling were used to analyze the effects of characteristics identified in the literature review and to estimate genetic and nongenetic variance components. The literature review identified 63 papers. Consistent with the review, we observed statistically significant effects of birth order, zygosity and gestational age (GA) for 1- and 5-min Apgar scores of both twins. Apgar scores are higher in first-born versus second-born twins and DZ first-born versus MZ first-born twins. Birth weight had an effect on the 5-min Apgar of the first born. Fetal presentation and mode of delivery had different effects on Apgar scores of first- and second-born twins. Parental characteristics and chorionicity did not have significant main effects on Apgar scores. The MZ twins' Apgar correlations equaled the DZ Apgar correlations. Our analyses suggest that individual differences in 1- and 5-min Apgar scores are attributable to shared and nonshared pre and perinatal factors, but not to genotypic factors of the newborns. The main predictors of Apgar scores are birth order, zygosity, GA, birth weight, mode of delivery and fetal presentation.

Abstract
The current study was designed to investigate the perinatal risk factors for low 1-min Apgar scores in term neonates. We retrospectively analyzed the maternal and neonatal clinical data of 10,550 infants who were born through vaginal delivery from 37 weeks 0 days to 41 weeks 6 days of single gestation from January 2013 to July 2018. Because the 1-min Apgar score reflects neonatal status at birth, we analyzed the risk factors for low (score <7) 1-min Apgar scores through logistic regression. Among these 10,550 neonates, 339 (3.2%) had low (score <7) 1-min Apgar scores. Among them, 321 (94.7%) were admitted to the neonatology department for further observation or treatment. Multivariate analysis revealed that educational background, body mass index, gestational age, pathological obstetrics, longer duration of the second stage of labor, forceps delivery or vacuum extraction, neonatal weight, neonatal sex, and meconium-stained amniotic fluid were independent risk factors for 1-min Apgar scores <7. Neonates who had low 1-min Apgar scores were more frequently admitted to the neonatology department for further observation or treatment. Early detection of risk factors and timely intervention to address these factors may improve neonatal outcomes at birth and reduce the rate of admission to the neonatology department.

Abstract
OBJECTIVE To test the non-inferiority of an alternative to the Apgar score. STUDY DESIGN The Neonatal Resuscitation and Adaptation Score (NRAS) was recorded in parallel to the Apgar score by a resuscitation team at deliveries. Correlation between the systems was assessed, as well as the predictive ability of NRAS and Apgar scores for mortality or short-term morbidities. RESULTS A total of 340 infants were in the study group. The two scores correlated strongly (r = 0.87 and 0.83 at 1 and 5 min, respectively). Those needing ventilation at 48 h of life had a 5-min NRAS < 7 in 23/26 vs Apgar < 7 (23/36, p = 0.001). A low (0-3) 1-min NRAS score was more predictive of death, 53% vs 17%, p = 0.0065. CONCLUSIONS NRAS correlates with Apgar status assessment, and identifies newborns who die or may require further care better than the Apgar score.

Abstract
Objective To compare Apgar scores of full-term newborns of mothers with gestational (GDM) or type II diabetes mellitus (T2DM) with scores of newborns of mothers without impaired glucose tolerance. Study design This was a retrospective data collection study (n=297). We reviewed 1-minute and 5-minute neonatal Apgar scores of newborns of mothers with GDM (n=100) or T2DM (n=97). Our control group consisted of newborns of mothers without a prior history of impaired glucose tolerance (n=100). ANOVA and linear model with corrected errors were used and adjusted for newborn sex and weight, and maternal age. Chi-squared analysis was performed for newborn sex. Results The mean 1-minute and 5-minute Apgar scores were 7.8 and 8.9 for the GDM group and 7.7 and 8.9 for the T2DM group, respectively. There was no statistical difference in the 1-minute and 5-minute Apgar scores between the GDM group and controls (P=0.89 and P=0.13, respectively) nor in the scores between the T2DM group and controls (P=0.67 and P=0.40, respectively). Conclusion Maternal history of GDM and T2DM does not appear to be associated with the 1-minute and 5-minute Apgar scores of full-term newborns of mothers with GDM and T2DM as compared to newborns of mothers without a history of impaired glucose tolerance.

Abstract
Low Apgar score has been associated with higher risk for several neurological and psychiatric disorders, including cerebral palsy and intellectual disability. Studies of the association between Apgar score and autism spectrum disorder (ASD) have been inconsistent. We aimed to investigate (1) the association between low Apgar score at 5 min and risk for ASD, and (2) the modifying effects of gestational age and sex on this association in the largest multinational database of ASD. We included prospective data from 5.5 million individuals and over 33,000 cases of ASD from Norway, Sweden, Denmark and Western Australia who were born between 1984 and 2007. We calculated crude and adjusted risk ratios (RR) with 95% confidence intervals (95% CIs) for the associations between low Apgar score and ASD. All analyses for ASD were repeated for autistic disorder (AD). We used interaction terms and stratified analysis to investigate the effects of sex, gestational age, and birth weight on the association. In fully adjusted models, low Apgar scores (1–3) (RR, 1.42; 95% CI, 1.16–1.74), and intermediate Apgar scores (4–6) (RR, 1.50; 95% CI, 1.36–1.65) were associated with a higher RR of ASD than optimal Apgar score (7–10). The point estimates for low (RR, 1.88; 95% CI, 1.41–2.51) and intermediate Apgar score (RR, 1.54; 95% CI, 1.32–1.81) were larger for AD than for ASD. This study suggests that low Apgar score is associated with higher risk of ASD, and in particular AD. We did not observe any major modifying effects of gestational age and sex, although there seems to be substantial confounding by gestational age and birth weight on the observed association.

Abstract
OBJECTIVE To investigate associations between Apgar score at five and 10 minutes across the entire range of score values (from 0 to 10) and risks of childhood cerebral palsy or epilepsy, and to analyse the effect of changes in Apgar scores from five to 10 minutes after birth in infants born ≥37 completed weeks. DESIGN, SETTING, AND PARTICIPANTS Population based cohort study in Sweden, including 1 213 470 non-malformed live singleton infants, born at term between 1999 and 2012. Data on maternal and pregnancy characteristics and diagnoses of cerebral palsy and epilepsy were obtained by individual record linkages of nationwide Swedish registries. EXPOSURES Apgar scores at five and 10 minutes. MAIN OUTCOME MEASURE Cerebral palsy and epilepsy diagnosed up to 16 years of age. Adjusted hazard ratios were calculated, along with 95% confidence intervals. RESULTS 1221 (0.1%) children were diagnosed as having cerebral palsy and 3975 (0.3%) as having epilepsy. Compared with children with an Apgar score of 10 at five minutes, the adjusted hazard ratio for cerebral palsy increased steadily with decreasing Apgar score: from 1.9 (95% confidence interval 1.6 to 2.2) for an Apgar score of 9 to 277.7 (154.4 to 499.5) for an Apgar score of 0. Similar and even stronger associations were obtained between Apgar scores at 10 minutes and cerebral palsy. Associations between Apgar scores and epilepsy were less pronounced, but increased hazard ratios were noted in infants with a five minute Apgar score of 7 or less and a 10 minute Apgar score of 8 or less. Compared with infants with an Apgar of 9-10 at both five and 10 minutes, hazard ratios of cerebral palsy and epilepsy were higher among infants with a five minute Apgar score of 7-8 and a 10 minute Apgar score of 9-10. CONCLUSION Risks of cerebral palsy and epilepsy are inversely associated with five minute and 10 minute Apgar scores across the entire range of Apgar scores.

Abstract
Introduction: The method of carrying out PTB is one of the most controversial topics of modern perinatology, because there are no clear and undeniable works and studies that would in any case support vaginal delivery (VD) or delivery to the cesarean section (CS). Aim: To determine more frequent mode of delivery in different groups of birth weights and degrees of prematurity from single and twin pregnancies. To determine the degree of vitality of premature born vaginal delivery (VD) in relation to the cesarean section (CS) in different degrees of prematurity from single and twin pregnancies. Patients and methods: Research has retrospective cohort character. Data were collected from the databases of University Clinic of Gynecology and Obstetrics Tuzla for the period of five years (January 1st, 2012–December 31st, 2016). The study included newborns of both genders, gestational age from 24 to 37 weeks of gestation (WG) in singleton and twin pregnancies. Results: Out of 19506 births, 1350 (6.92%) were preterm birth (PTB). Singleton PTB was 1180 (87.40%), and the twins were 170 (12.59%). Vaginal delivery (VD) was born 788 (58.37%). Cesarean section (CS) was born 562 (41.63%). There was statistically significant association between the mode of delivery (MD) in singleton and twins pregnancy in all three subgroups of birth weight (BW) 1000-1499, 2000-2499 and >2500 grams in 33-37 WG. In this group was more frequent VD than CS mode of singleton delivery, and CS than VD mode of twins delivery. In contrast to newborn with BW 1500-1999 grams (chi-square = 23.16, P <0.0001) in same gestational period where was more frequent CS than VD (OR: 2.56, 95% CI: 1.71-3,85). Apgar score (AS) at first and five minute 5-7 and 8-10 in the period 28-32 and 33-37 was a statistically significant frequent in VD and singletons in contrast to CS and twins. Conclusion: VD was more frequent in the higher WG, as well as the higher AS in singletons in contrast to twins delivery.

Abstract
BACKGROUND The Apgar score consists of five components: heart rate, respiratory effort, muscle tone, reflex irritability, and colour. Although the Apgar score has been used for 60 years, the specific contribution of the Apgar score components with respect to risks and prediction of neonatal mortality remains unknown. Likewise, the value of reduced scores (including less than five Apgar score components) has rarely been investigated. METHODS In a population-based cohort study of 148 765 liveborn singleton infants in Sweden 2008-2013, we investigated components of Apgar score at 5 min with respect to relative risks and prediction (using ROC curves, sensitivity, and positive predictive values) of neonatal mortality. RESULTS Reduced values (0-1) of heart rate, respiratory effort, and colour were independently associated with increased relative risks of neonatal mortality. For the full Apgar score, the sensitivity and positive predictive values of neonatal mortality (cut-off ≤3) were by gestational age: ≤31 weeks: 56.1% and 49.2%; 32-36 weeks: 25.0% and 18.2%; and ≥37 weeks: 35.2% and 9.3%, respectively. When only heart rate and respiratory effort were considered (range 0-4; cut-off ≤2), corresponding values were 66.7% and 34.9%; 37.5% and 13.0%; and 46.3% and 7.6%, respectively. CONCLUSIONS A reduced Apgar score has generally the same predictability of neonatal mortality as the full Apgar score. The full Apgar score or reduced scores may be better predictors of neonatal mortality in very preterm infants (≤31 weeks) than in infants with longer gestations.

Abstract
OBJECTIVE Though no official guidelines address the issue of the optimal timing of delivery in placenta previa, common practice is to conduct delivery between 36 and 37 weeks gestation. Given the rising concerns regarding unnecessary premature deliveries, the objective of this study was to compare neonatal outcomes among pregnancies complicated by placenta previa delivered at the late-preterm period (35, 36 weeks) relative to the early-term period (37 and 38 weeks). METHODS We conducted a retrospective, population-based, cohort study using the CDC’s Linked Birth-Infant Death data files from the U.S. for the year 2004. We stratified the cohort according to gestational age and placenta previa status. Using 38 weeks gestation as reference controls, the effect of delivery in a pregnancy with placenta previa at 35, 36 and 37 weeks gestation on the risk of several neonatal outcomes was estimated using logistic regression analysis, adjusting for relevant confounders. RESULTS We analyzed a total of 4 118 956 births, of which 5675 (0.1%) met inclusion criteria. Late-preterm delivery was associated with lower birthweight and increased adequacy of care. Relative to neonates born at 38 weeks, birth at 35, 36 and 37 weeks was associated with no greater odds of meconium passage, fetal distress, fetal anemia, neonatal seizures, increased ventilator needs, or infant death at 1 year. However, odds of 5-min APGAR scores <7 were greater at 35 and 36 weeks (aOR [95% CI]): 3.33 [1.71-6.47] and 2.17 [1.11-4.22], respectively; as were odds of NICU admission rates: 2.25 [2.01-2.50] and 1.57 [1.38-1.76], respectively. Conclusions: Barring maternal indications, early-term delivery in placenta previa is associated with fewer complications and no greater risk than late-preterm delivery. This information may be helpful in the development of future guidelines, which are currently needed to guide the management of these pregnancies.

Abstract
The Apgar score provides an accepted and convenient method for reporting the status of the newborn infant immediately after birth and the response to resuscitation if needed. The Apgar score alone cannot be considered to be evidence of or a consequence of asphyxia, does not predict individual neonatal mortality or neurologic outcome, and should not be used for that purpose. An Apgar score assigned during a resuscitation is not equivalent to a score assigned to a spontaneously breathing infant. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists encourage use of an expanded Apgar score reporting form that accounts for concurrent resuscitative interventions.

Abstract
OBJECTIVES To investigate the risk of adverse perinatal outcomes in women aged ≥41 years relatively to those aged 21-34. METHODS Approximately 8.5 million records of singleton births in Brazilian hospitals in the period 2004-2009 were investigated. Odds ratios were estimated for preterm and post-term births, for low Apgar scores at 1 min and at 5 min, for asphyxia, for low birth weight, and for macrosomia. RESULTS For pregnant women ≥41, increased risks were identified for preterm births, for post-term births (except for primiparous women with schooling ≥12 years), and for low birth weight. When comparing older vs. younger women, higher educational levels ensure similar risks of low Apgar score at 1 min (for primiparous mothers and term births), of low Apgar score at 5 min (for term births), of macrosomia (for non-primiparous women), and of asphyxia. CONCLUSION As a rule, older mothers are at higher risk of adverse perinatal outcomes, which, however, may be mitigated or eliminated, depending on gestational age, parity, and, especially, on the education level of the pregnant woman.

Abstract
This study evaluated the interrater reliability and perceived importance of components of a developed neonatal adaption score, Neonatal Resuscitation Adaptation Score (NRAS), for evaluation of resuscitation need in the delivery room for extremely premature to term infants. Similar to the Apgar, the NRAS highest score was 10, but greater weight was given to respiratory and cardiovascular parameters. Evaluation of provider (N = 17) perception and scoring pattern was recorded for 5 clinical scenarios of gestational ages 23 to 40 weeks at 1 and 5 minutes and documenting NRAS and Apgar score. Providers assessed the tool twice within a 1-month interval. NRAS showed superior interrater reliability (P < .001) and respiratory component reliability (P < .001) for all gestational ages compared to the Apgar score. These findings identify an objective tool in resuscitation assessment of infants, especially those of smaller gestation age, allowing for greater discrimination of postbirth transition in the delivery room.

Abstract
BACKGROUND AND OBJECTIVES Existing data on pregnancy complications in inflammatory bowel disease (IBD) are inconsistent. To address these inconsistencies, we investigated potential associations between IBD, IBD-related medication use during pregnancy, and pregnancy loss, pre-eclampsia, preterm delivery, Apgar score, and congenital abnormalities. METHODS We conducted a cohort study in >85,000 Danish National Birth Cohort women who were pregnant in the period 1996-2002 and had information on IBD, IBD-related medication use (systemic or local corticosteroids, 5-aminosalicylates), pregnancy outcomes and potential confounders. We evaluated associations between IBD and adverse pregnancy/birth outcomes using Cox regression and log-linear binomial regression. RESULTS IBD was strongly and significantly associated with severe pre-eclampsia, preterm premature rupture of membranes and medically indicated preterm delivery in women using systemic corticosteroids during pregnancy (hazard ratios [HRs] >7). IBD was also associated with premature preterm rupture of membranes in women using local corticosteroid medications (HR 3.30, 95% confidence interval [CI] 1.33-8.20) and with medically indicated preterm delivery (HR 1.91, 95% CI 0.99-3.68) in non-medicated women. Furthermore, IBD was associated with low 5-minute Apgar score in term infants (risk ratio [RR] 2.19, 95% CI 1.03-4.66). Finally, Crohn's disease (but not ulcerative colitis) was associated with major congenital abnormalities in the offspring (RR 1.85, 95% CI 1.06-3.21). No child with a congenital abnormality born to a woman with IBD was exposed to systemic corticosteroids in utero. CONCLUSION Women with IBD are at increased risk of severe pre-eclampsia, medically indicated preterm delivery, preterm premature rupture of membranes, and delivering infants with low Apgar score and major congenital malformations. These associations are only partly explained by severe disease as reflected by systemic corticosteroid use.

Abstract
Brominated flame retardants (BFRs) and other persistent organic pollutants have been associated with adverse health outcomes in humans and may be particularly toxic to the developing fetus. We investigated the association between in utero polybrominated biphenyl (PBB) and polychlorinated biphenyl (PCB) exposures and infant Apgar scores in a cohort of Michigan residents exposed to PBB through contaminated food after an industrial accident. PBB and PCB concentrations were measured in serum at the time the women were enrolled in the cohort. PBB concentrations were also estimated at the time of conception for each pregnancy using a validated elimination model. Apgar scores, a universal measure of infant health at birth, measured at 1 and 5min, were taken from birth certificates for 613 offspring born to 330 women. Maternal PCB concentrations at enrollment were not associated with below-median Apgar scores in this cohort. However, maternal PBB exposure was associated with a dose-related increase in the odds of a below-median Apgar score at 1min and 5min. Among infants whose mothers had an estimated PBB at conception above the limit of detection of 1 part per billion (ppb) to <2.5ppb, the odds ratio=2.32 (95% CI: 1.22-4.40); for those with PBB⩾2.5ppb the OR=2.62 (95% CI: 1.38-4.96; test for trend p<0.01). Likewise, the odds of a below-median 5min Apgar score increased with higher maternal PBB at conception. It remains critical that future studies examine possible relationships between in utero exposures to brominated compounds and adverse health outcomes.

Abstract
BACKGROUND The Apgar score has been used worldwide as an index of early neonatal condition for more than 60 years. With advances in health-care service provision, neonatal resuscitation, and infant care, its present relevance is unclear. The aim of the study was to establish the strength of the relation between Apgar score at 5 min and the risk of neonatal and infant mortality, subdivided by specific causes. METHODS We linked routine discharge and mortality data for all births in Scotland, UK between 1992 and 2010. We restricted our analyses to singleton livebirths, in women aged over 10 years, with a gestational age at delivery between 22 and 44 weeks, and excluded deaths due to congenital anomalies or isoimmunisation. We calculated the relative risks (RRs) of neonatal and infant death of neonates with low (0-3) and intermediate (4-6) Apgar scores at 5 min referent to neonates with normal Apgar score (7-10) using binomial log-linear modelling with adjustment for confounders. Analyses were stratified by gestational age at birth because it was a significant effect modifier. Missing covariate data were imputed. FINDINGS Complete data were available for 1,029,207 eligible livebirths. Across all gestational strata, low Apgar score at 5 min was associated with an increased risk of neonatal and infant death. However, the strength of the association (adjusted RR, 95% CI referent to Apgar 7-10) was strongest at term (p<0·0001). A low Apgar (0-3) was associated with an adjusted RR of 359·4 (95% CI 277·3-465·9) for early neonatal death, 30·5 (18·0-51·6) for late neonatal death, and 50·2 (42·8-59·0) for infant death. We noted similar associations of a lower magnitude for intermediate Apgar (4-6). The strongest associations were for deaths attributed to anoxia and low Apgar (0-3) for term infants (RR 961·7, 95% CI 681·3-1357·5) and preterm infants (141·7, 90·1-222·8). No association between Apgar score at 5 min and the risk of sudden infant death syndrome was noted at any gestational age (RR 0·6, 95% CI 0·1-4·6 at term; 1·2, 0·3-4·8 at preterm). INTERPRETATION Low Apgar score at 5 min was strongly associated with the risk of neonatal and infant death. Our findings support its continued usefulness in contemporary practice. FUNDING None.

Abstract
OBJECTIVES The causes of congenital permanent hearing loss in children are insufficiently understood. We studied the association of Apgar score 5 min after birth with sensorineural hearing loss diagnosed before the age of 5 years. METHODS We performed an epidemiological cohort study with data obtained by linkage between The Medical Birth Registry of Norway and the Norwegian County Registry of Children with Hearing Loss. Cases were 327 children born in Norway during the period 1978-1998 with sensorineural hearing loss. Controls were all children in Norway without sensorineural hearing loss born in the same counties and during the same period as the cases (n=392,044). The associations of Apgar score 5 min after birth with sensorineural hearing loss were estimated as odds ratios (OR) with 95% confidence intervals (CI) by applying logistic regression analyses. RESULTS Among children with sensorineural hearing loss 0.9% (3/327) had Apgar score<3, whereas that was true for 0.1% (304/392044) of children without hearing loss (p=0.001, chi square test). The aOR for sensorineural hearing loss was 7.5 [95% CI 2.3-, 24.2] comparing Apgar score<3 to Apgar score 10, after adjustment for birthweight and concurrent birth defects. Most children with sensorineural hearing loss (90%) had Apgar score>8 five minutes after birth. CONCLUSIONS Low Apgar score was associated with childhood sensorineural hearing loss. However, most children with sensorineural hearing loss, had Apgar score>8.

Abstract
Background Data pertaining to risk factors associated with stillbirths and very low Apgar scores is very sparse. This study was conducted to determine the prevalence of, and examine the socio-demographic and obstetric factors associated with stillbirths and very low Apgar scores among vaginal births in a tertiary health facility, Ghana. Methods A retrospective cross-sectional review of vaginal deliveries conducted at a teaching hospital in Ghana from 1st January to 31st December, 2009. Background characteristics and obstetric history of the mother as well as the vital status of the baby at birth were extracted. Risk factors associated with stillbirths and very low Apgar scores were examined using binomial regression with a log-link function, and population attributable fractions calculated for significant risk factors. Results Of the 8,758 deliveries which met the inclusion criteria, 5.9% of the babies were stillbirths, and 6.5% and 1.9% of live births had very low Apgar scores in the first and fifth minutes respectively. Preterm delivery, hypertensive disorders in pregnancy, breech delivery and vacuum extraction were significant risk factors for stillbirths and very low Apgar scores in the fifth minute of life. Low birth weight was also a significant risk factor for very low Apgar scores. Conclusion The prevalence of stillbirths and very low Apgar scores were high. Improving the quality of obstetric care during labour and delivery may help improve these adverse vaginal birth outcomes.

Abstract
OBJECTIVE To examine differences in maternal characteristics and pregnancy outcomes between women with ovulatory dysfunction (OD) and women with tubal obstruction (TO) who underwent assisted reproductive technology (ART). DESIGN Retrospective cohort study. SETTING Centers for Disease Control and Prevention. PATIENT(S) Exposed and nonexposed groups were selected from the 2000-2006 National ART Surveillance System linked with live-birth certificates from three states: Florida, Massachusetts, and Michigan. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Maternal characteristics and pregnancy outcomes, including newborn's health status right after delivery (Apgar score, <7 vs. ≥ 7) as the study outcome of interest, were assessed among women with OD/polycystic ovary syndrome (PCOS) and TO who used ART. RESULT(S) A significantly higher prevalence of women with OD/PCOS were younger (<35 years of age; 65.7% vs. 48.9%), were white (85.4% vs. 74.4%), had higher education (29.4% vs. 15.6%), and experienced diabetes (8.8% vs. 5.3%) compared with those having TO. The odds of having a lower (<7) Apgar score at 5 minutes were almost twice as high among newborns of women with OD/PCOS compared with those with TO (crude odds ratio, 1.86; 95% confidence interval [CI], 1.31, 2.64; adjusted odds ratio, 1.90; 95% CI, 1.30, 2.77). CONCLUSION(S) Women with OD/PCOS who underwent ART have different characteristics and health issues (higher prevalence of diabetes) and infant outcomes (lower Apgar score) compared with women with TO.

Abstract
OBJECTIVE Measuring the quality of inpatient obstetrical care using quality indicators is becoming increasingly important for both patients and healthcare providers. However, there is no consensus about which measures are optimal. We describe a modified Delphi method to identify a set of indicators for continuously monitoring the quality of maternity care by healthcare professionals. METHODOLOGY AND MAIN FINDINGS An international French-speaking multidisciplinary panel comprising 22 obstetricians-gynaecologists, 12 midwives, and 1 paediatrician assessed potential indicators extracted from a medical literature search, using a two-round Delphi procedure followed by a physical meeting. Each panellist rated each indicator based on validity and feasibility. In the first round, 35 panellists from 5 countries and 20 maternity units evaluated 26 indicators including 15 related to the management of the overall population of pregnant women, 3 to the management of women followed from the first trimester of pregnancy, 2 to the management of low-risk pregnant women, and 6 to the management of neonates. 25 quality indicators were kept for next step. In the second round, 27 (27/35: 77%) panellists selected 17 indicators; the remaining 8 indicators were discussed during a physical meeting. The final set comprised 18 indicators. CONCLUSION A multidisciplinary panel selected indicators that reflect the quality of obstetrical care. This set of indicators could be used to assess and monitor obstetrical care, with the goal of improving the quality of care in maternity units.

Abstract
AIM To determine the normal SpO2 in healthy term newborns at mild altitude (MA, 780 metres) compared with sea level (SL), within the context of universal screening for critical congenital heart disease (CCHD). METHODS We studied 199 (119 at MA and 80 at SL) consecutively born healthy newborns. SpO2 recordings were at 24-72 h using Masimo SET Radical-7 on the right hand and left foot. RESULTS Mean SpO2 was lower at MA compared with SL in the right hand (97.86 ± 1.58 vs 98.28 ± 1.41, p = 0.05) and left foot (98.49 ± 1.35 vs 98.90 ± 1.16, p = 0.03). No infant with SpO2 <95% had CCHD. Extrapolating with predicted regression lines set at 95% CI, a SpO2 cut-off of 95% would result in up to 3.5 times more false-positive screens at MA compared with SL. CONCLUSIONS At MA, SpO2 is approximately 0.4% lower compared with SL. Our study supports the AAP recommendation suggesting algorithm cut-offs may need adjustment in high-altitude nurseries and suggest broadening it to MA as well.

Abstract
BACKGROUND The accepted standard for assessing the wellbeing of the newborn is the Apgar score and blood gas analysis. However, the prediction of neonatal morbidity or mortality is limited. In small-for-gestation (SGA) fetuses at 18-38 weeks of gestation, pO(2) is <5th centile both in the umbilical artery and vein in 30%. In a previous study in singleton term neonates cardiac specific enzymes (B-type natriuretic peptide, BNP and cardiac troponin T, cTnT) are increased in growth-restricted fetuses compared with normals. AIMS To test the hypothesis, that fetuses with intra uterine growth restriction (IUGR) have elevated AST (GOT) and ALT (GPT) aminotransferases as a result of hypoxic liver cell injury, and to establish references ranges. STUDY DESIGN Prospective cohort study, serum of umbilical artery (n=156) and vein (n=180), 599 normal singletons at 37(+0)-42(+0)weeks, neonates with IUGR (n=41), analysis for pH, birthweight and maternal weight, spontaneous vs cesarean section, vein vs artery and for the sex. OUTCOME MEASURES Aspartate aminotransferase (AST, GOT) and Alanine aminotransferase (ALT, GPT) were measured in normals and IUGR neonates. RESULTS Neonates with IUGR (n=41) had AST values that were not different from the reference group, but had significantly lower ALT (-1.49, 95% CI -1.98 to -1.00 vs 0.14, 95% CI -0.42-0.13), (p<0.001), (Fig. 3). CONCLUSIONS In neonates with IUGR, hypoxic hepatic injury markers in cord blood were not elevated. Rather, a substantially reduced ALT suggests a down-regulated hepatic activity.

Abstract
Prenatal depression has been linked to adverse reproductive outcomes including preterm labor and delivery, and low birth weight. Social support also has been linked to birth outcomes, and may buffer infants from the adverse impact of maternal depression. In this prospective study, 235 pregnant women completed questionnaires about depression and social support. Clinical interviews were administered to assess for DSM-IV axis I disorders. Following delivery, birth outcomes were obtained from medical records. Babies of depressed mothers weighed less, were born earlier and had lower Apgar scores than babies of nondepressed mothers. Depressed women had smaller social support networks and were less satisfied with support from social networks. We found no direct associations between perceived social support and birth weight. However, depressed women who rated their partners as less supportive had babies who were born earlier and had lower Apgar scores than depressed mothers with higher perceived partner support. Women's perception of partner support appears to buffer infants of depressed mothers from potential adverse outcomes. These results are notable in light of the low-risk nature of our sample and point to the need for continued depression screening in pregnant women and a broader view of risk for adverse birth outcomes. The results also suggest a possible means of intervention that may ultimately lead to reductions in adverse birth outcomes.

Abstract
AIM To quantify the relationship between 5-min Apgar scores and infant mortality for infants at the borderline of viability. METHODS Cohort study of 7008 infants 23-25 weeks' gestation using 2002 US National Center for Health Statistics data. Using Cox proportional-hazards models, we quantified the relationship between Apgar score and infant mortality for all infants, and then infants surviving their first 24 h. Models were adjusted for gestational age, birth weight, gender, delivery method, plurality, maternal race, marital status and education. RESULTS Within one year, 46% of infants died. Of the non-survivors, deaths within 24 h were more common among infants with Apgar scores 0-3 (83%) than among infants with Apgar scores 7-10 (13%). When including all infants and adjusting for potential confounders, each 1-point increase in Apgar score decreased the hazard of mortality by 0.82. However, after excluding infants who died within 24 h, the hazard ratio increased to 0.95; although statistically significant, the practical impact was negated. CONCLUSIONS For 23-25 week gestation infants surviving the first 24 h, the Apgar score loses clinical significance. Clinicians should be aware of the limitations of clinical assessments in the delivery room.
