African Health Sciences Sep 2023Apgar score is conducted to a baby immediately after birth checking how the baby tolerated the birth process and outside the uterus.
INTRODUCTION
Apgar score is conducted to a baby immediately after birth checking how the baby tolerated the birth process and outside the uterus.
OBJECTIVES
To describe the neonatal factors associated with immediate low Apgar score and analysing the associations among factors associated with low Apgar score in new-born babies.
METHODS
A quantitative, case-control, descriptive research design was used. Study population were all maternal records of deliveries conducted between 01 January 2019 and 31 December 2019. Simple random sampling was used to select the sample size for 194 cases and 194 controls using a 1:1 case-control ratio. Records indicating low Apgar scores were the cases while normal Apgar scores were the controls. A total of 388 maternal files were reviewed. Data were collected using a document review checklist and analysed using SPSS version 26.
RESULTS
The study found that, neonatal factors associated with immediate low Apgar score are; gestational age, foetal presentation, cord prolapse, cord around the neck and the importance of cardiotocography interpretation as they had a P-value > 0.005.
CONCLUSION
Gestational age, birth weight, foetal presentation, cord around the neck and lack of cardiotocography assessment were found to be associated with immediate low Apgar score.

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.

Meta-Analysis Review
BACKGROUND
The progress of labour in the early or latent phase is usually slow and may include painful uterine contractions. Women may feel distressed and lose their confidence during this phase. Support and assessment interventions have been assessed in two previous Cochrane Reviews. This review updates and replaces these two reviews, which have become out of date.
OBJECTIVES
To investigate the effectiveness of assessment and support interventions for women during early labour.In order to measure the effectiveness of the interventions, we compared the duration of labour, the rate of obstetrical interventions, and the rate of other maternal or neonatal outcomes.
SEARCH METHODS
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (31 October 2016) and reference lists of retrieved studies.
SELECTION CRITERIA
Randomised controlled trials of any assessment or support intervention in the latent phase of labour. We planned to include cluster-randomised trials if they were eligible. We did not include quasi-randomised trials.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We resolved any disagreement by discussion or by involving a third assessor. The quality of the evidence was assessed using the GRADE approach.
MAIN RESULTS
We included five trials with a total of 10,421 pregnant women in this review update. The trials were conducted in the UK, Canada and America. The trials compared interventions in early labour versus usual care. We examined three comparisons: early labour assessment versus immediate admission to hospital; home visits by midwives versus usual care (telephone triage); and one-to-one structured midwifery care versus usual care. These trials were at moderate- risk of bias mainly because blinding women and staff to these interventions is not generally feasible. For important outcomes we assessed evidence using GRADE; we downgraded evidence for study design limitations, imprecision, and where we carried out meta-analysis, for inconsistency.One trial with 209 women compared early labour assessment with direct admission to hospital. Duration of labour from the point of hospital admission was reduced for women in the assessment group (mean difference (MD) -5.20 hours, 95% confidence interval (CI) -7.06 to -3.34; 209 women, low-quality evidence). There were no clear differences between groups for the number of women undergoing caesarean section or instrumental vaginal birth (risk ratio (RR) 0.72, 95% CI 0.30 to 1.72, very low quality evidence; and, RR 0.86, 95% CI 0.58 to 1.26, very low quality evidence, respectively). Serious maternal morbidity was not reported. Women in the early assessment group were slightly less likely to have epidural anaesthesia (RR 0.87, 95% CI 0.78 to 0.98, low-quality evidence), and considerably less likely to have oxytocin for labour augmentation (RR 0.57, 95% CI 0.37 to 0.86) and this group also had increased satisfaction with their care compared with women in the immediate admission group (MD 16.00, 95% CI 7.53 to 24.47). No babies were born before admission to hospital and only one infant had a low Apgar score at five minutes after the birth (very low quality evidence). Admission to neonatal special care was not reported.Three studies examined home assessment and midwifery support versus telephone triage. One trial reported the duration of labour; home visits did not appear to have any clear impact compared with usual care (MD 0.29 hours, 95% CI -0.14 to 0.72; 1 trial, 3474 women, low-quality evidence). There was no clear difference for the rate of caesarean section (RR 1.05, 95% CI 0.95 to 1.17; 3 trials, 5170 women; I² = 0%; moderate-quality evidence) or the rate of instrumental vaginal birth (average RR 0.95, 95% CI 0.79 to 1.15; 2 trials, 4933 women; I² = 69%; low-quality evidence). One trial reported birth before arrival at hospital or unplanned home birth; there was no clear difference between the groups (RR 1.33, 95% CI 0.30 to 5.95; 1 trial, 3474 women). No clear differences were identified for serious maternal morbidity (RR 0.93, 95% CI 0.61 to 1.42; 1 trial, 3474 women; low-quality evidence), or use of epidural (average RR 0.95, 95% CI 0.87 to 1.05; 3 trials, 5168 women; I² = 60%; low-quality evidence). There were no clear differences for neonatal admission to special care (average RR 0.84, 95% CI 0.50 to 1.42; 3 trials, 5170 infants; I² = 71%; very low quality evidence), or for Apgar score less than seven at five minutes after birth (RR 1.19, 95% CI 0.71 to 1.99; 3 trials, 5170 infants; I² = 0%; low-quality evidence).One study, with 5002 women, examined one-to-one structured care in early labour versus usual care. Length of labour was not reported. There were no clear differences between groups for the rate of caesarean section (RR 0.93, 95% CI 0.84 to 1.02; 4996 women, high-quality evidence), or for instrumental vaginal birth (RR 0.94, 95% CI 0.82 to 1.08; 4996 women, high-quality evidence). No clear differences between groups were reported for serious maternal morbidity (RR 1.13, 95% CI 0.84 to 1.52; 4996 women, moderate-quality evidence). Use of epidural was similar in the two groups (RR 1.00, 95% CI 0.99 to 1.01; 4996 women, high-quality evidence). For infant outcomes, there were no clear differences between groups (admission to neonatal intensive care unit: RR 0.98, 95% CI 0.80 to 1.21; 4989 infants, high-quality evidence; Apgar score less than seven at five minutes: RR 1.07, 95% CI 0.64 to 1.79; 4989 infants, moderate-quality evidence).
AUTHORS' CONCLUSIONS
Assessment and support in early labour does not have a clear impact on rate of caesarean section or instrumental vaginal birth, or whether the baby was born before arrival at hospital or in an unplanned home birth. However, evidence suggested that interventions may have an impact on reducing the use of epidural anaesthesia, labour augmentation and on increasing maternal satisfaction with giving birth. Evidence about the effectiveness of early labour assessment versus immediate admission was very limited and more research is needed in this area.

Although Brazil has reduced social, economic and health indicators disparities in the last decade, intra- and inter-regional differences in child mortality rates (CMR) persist in regions such as the state capital of Mato Grosso. This population-based study aimed to investigate factors associated with child mortality in five cohorts of live births (LB) of mothers living in Cuiabá (MT), Brazil, 2006-2010, through probabilistic linkage in 47,018 LB. We used hierarchical logistic regression analysis. Of the 617 child deaths, 48% occurred in the early neonatal period. CMR ranged from 14.6 to 12.0 deaths per thousand LB. The following remained independently associated with death: mothers without companion (OR = 1.32); low number of prenatal consultations (OR = 1.65); low birthweight (OR = 4.83); prematurity (OR = 3.05); Apgar ≤ 7 at the first minute (OR = 3.19); Apgar ≤ 7 at the fifth minute (OR = 4.95); congenital malformations (OR = 14.91) and male gender (OR = 1.26). CMR has declined in Cuiabá, however, there is need to guide public healthcare policies in the prenatal and perinatal period to reduce early neonatal mortality and further studies to identify the causes of preventable deaths.

BACKGROUND
Pregnancy associated cancer (PAC) may lead to adverse obstetric and neonatal outcomes. This study aims to assess the association between PACs and adverse perinatal outcomes [i.e. labor induction, iatrogenic delivery, preterm birth, small for gestational age (SGA) newborn, low Apgar score, major malformations, perinatal mortality] in Lombardy, Northern Italy.
METHODS
This population-based historic cohort study used the certificate of delivery assistance and the regional healthcare utilization databases of Lombardy Region to identify beneficiaries of National Health Service who delivered between 2008 and 2017. PACs were defined through oncological ICD-9-CM codes reported in the hospital discharge forms. Each woman with PAC was matched to four women randomly selected from those cancer-free (1:4). Log-binomial regression models were fitted to estimate crude and adjusted prevalence ratio (aPR) and the corresponding 95% confidence interval (CI) of each perinatal outcome among PAC and cancer-free women.
RESULTS
Out of the 657,968 deliveries, 831 PACs were identified (1.26 per 1000). PAC diagnosed during pregnancy was positively associated with labor induction or planned delivery (aPR=1.80, 95% CI: 1.57-2.07), cesarean section (aPR=1.78, 95% CI: 1.49-2.11) and premature birth (aPR=6.34, 95% CI: 4.59-8.75). No association with obstetric outcomes was found among PAC diagnosed in the post-pregnancy. No association of PAC, neither during pregnancy nor in post-pregnancy was found for SGA (aPR=0.71, 95% CI: 0.36-1.35 and aPR=1.04, 95% CI: 0.78-1.39, respectively), but newborn among PAC women had a lower birth weight (p-value< 0.001). Newborns of women with PAC diagnosed during pregnancy had a higher risk of borderline significance of a low Apgar score (aPR=2.65, 95% CI: 0.96-7.33) as compared to cancer-free women.
CONCLUSION
PAC, especially when diagnosed during pregnancy, is associated with iatrogenic preterm delivery, compromising some neonatal heath indicators.

Although Apgar scores are commonly used as proxy outcomes, little evidence exists in support of the most common cutpoints (<7, <4). We used 2 data sets to explore this issue: one contained planned community births from across the United States (n = 52,877; 2012-2016), and the other contained hospital births from California (n = 428,877; 2010). We treated 5-minute Apgars as clinical "tests," compared against 18 known outcomes; we calculated sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve for each. We used 3 different criteria to determine optimal cutpoints. Results were very consistent across data sets, outcomes, and all subgroups: The cutpoint that maximizes the trade-off between sensitivity and specificity is universally <9. However, extremely low positive predictive values for all outcomes at <9 indicate more misclassification than is acceptable for research. The areas under the receiver operating characteristic curves (which treat Apgars as quasicontinuous) were generally indicative of adequate discrimination between infants destined to experience poor outcomes and those not; comparing median Apgars between groups might be an analytical alternative to dichotomizing. Nonetheless, because Apgar scores are not clearly on any causal pathway of interest, we discourage researchers from using them unless the motivation for doing so is clear.

Comparative Study
BACKGROUND
While previous studies identified risk factors for diverse pregnancy outcomes, traditional statistical methods had limited ability to quantify their impacts on birth outcomes precisely. We aimed to use a novel approach that applied different machine learning models to not only predict birth outcomes but systematically quantify the impacts of pre- and post-conception serum thyroid-stimulating hormone (TSH) levels and other predictive characteristics on birth outcomes.
METHODS
We used data from women who gave birth in Shanghai First Maternal and Infant Hospital from 2014 to 2015. We included 14,110 women with the measurement of preconception TSH in the first analysis and 3,428 out of 14,110 women with both pre- and post-conception TSH measurement in the second analysis. Synthetic Minority Over-sampling Technique (SMOTE) was applied to adjust the imbalance of outcomes. We randomly split (7:3) the data into a training set and a test set in both analyses. We compared Area Under Curve (AUC) for dichotomous outcomes and macro F1 score for categorical outcomes among four machine learning models, including logistic model, random forest model, XGBoost model, and multilayer neural network models to assess model performance. The model with the highest AUC or macro F1 score was used to quantify the importance of predictive features for adverse birth outcomes with the loss function algorithm.
RESULTS
The XGBoost model provided prominent advantages in terms of improved performance and prediction of polytomous variables. Predictive models with abnormal preconception TSH or not-well-controlled TSH, a novel indicator with pre- and post-conception TSH levels combined, provided the similar robust prediction for birth outcomes. The highest AUC of 98.7% happened in XGBoost model for predicting low Apgar score with not-well-controlled TSH adjusted. By loss function algorithm, we found that not-well-controlled TSH ranked 4, 6, and 7 among 14 features, respectively, in predicting birthweight, induction, and preterm birth, and 3 among 19 features in predicting low Apgar score.
CONCLUSIONS
Our four machine learning models offered valid predictions of birth outcomes in women during pre- and post-conception. The predictive features panel suggested the combined TSH indicator (not-well-controlled TSH) could be a potentially competitive biomarker to predict adverse birth outcomes.

BACKGROUND
Umbilical cord blood gases are routinely used by midwives and obstetricians for quality assurance of birth management and in clinical research. They can form the basis for solving medicolegal issues in the identification of severe intrapartum hypoxia at birth. However, the scientific value of veno-arterial differences in cord blood pH, also known as ΔpH, is largely unknown. By tradition, the Apgar score is frequently used to predict perinatal morbidity and mortality, however significant inter-observer and regional variations decrease its reliability and there is a need to identify more accurate markers of perinatal asphyxia. The aim of our study was to investigate the association of small and large veno-arterial differences in umbilical cord pH, ΔpH, with adverse neonatal outcome.
METHODS
This retrospective, population-based study collected obstetric and neonatal data from women giving birth in nine maternity units from Southern Sweden from 1995 to 2015. Data was extracted from the Perinatal South Revision Register, a quality regional health database. Newborns at ≥37 gestational weeks with a complete and validated set of umbilical cord blood samples from both cord artery and vein were included. Outcome measures included: ΔpH percentiles, 'Small ΔpH' (10th percentile), 'Large ΔpH' (90th percentile), Apgar score (0-6), need for continuous positive airway pressure (CPAP) and admission to neonatal intensive care unit (NICU). Relative risks (RR) were calculated with modified Poisson regression model.
RESULTS
The study population comprised of 108,629 newborns with complete and validated data. Mean and median ΔpH was 0.08 ± 0.05. Analyses of RR showed that 'Large ΔpH' was associated with a decreased RR of adverse perinatal outcome with increasing UApH (at UApH ≥7.20: RR for low Apgar 0.29, P = 0.01; CPAP 0.55, P = 0.02; NICU admission 0.81, P = 0.01). 'Small ΔpH' was associated with an increased RR for low Apgar score and NICU admission only at higher UApH values (at UApH 7.15-7.199: RR for low Apgar 1.96, P = 0.01; at UApH ≥7.20: RR for low Apgar 1.65, P = 0.00, RR for NICU admission 1.13, P = 0.01).
CONCLUSION
Large differences between cord venous and arterial pH (ΔpH) at birth were associated with a lower risk for perinatal morbidity including low 5-minute Apgar Score, the need for continuous positive airway pressure and NICU admission when UApH was above 7.15. Clinically, ΔpH may be a useful tool in the assessment of the newborn's metabolic condition at birth. Our findings may stem from the ability of the placenta to adequately replenish acid-base balance in fetal blood. 'Large ΔpH' may therefore be a marker of effective gas exchange in the placenta during birth.

INTRODUCTION
Despite much literature on reference values of acid-base status in umbilical cord blood at birth, there are as yet no studies performed to determine gestational age-dependent references in cord venous blood and no studies on preterm acid-base standards. Similarly, the normal reference range of Apgar scores for term and preterm infants has not yet been determined.
MATERIAL AND METHODS
Data were obtained from the maternity units of Skåne University Hospital, Malmö and Lund, Sweden, from 2001 to 2010. Validated paired arterial and venous cord pH values were obtained from 27 175 newborns, of whom 18 584 had spontaneous, non-instrumental vaginal deliveries and a 5-minute Apgar score equal to or greater than the median value for the individual gestational week. Simple linear and polynomial regression analyses were performed. Values were reported as mean ± standard deviation and median with 2.5th and 97.5th percentiles.
RESULTS
Median 5-minute Apgar score was 7 for gestations shorter than 28 weeks, 8 for 28 weeks, 9 for 29-30 weeks, and 10 from 31 weeks onwards. A linear decline in pH for both cord arterial and venous blood was seen with advancing gestational age (P < 0.001).
CONCLUSIONS
Median 5-minute Apgar scores were <10 before 31 weeks of gestation. Both umbilical cord arterial and venous pH decreased linearly with increasing gestational age. Further studies are needed to show whether gestational age-related pH reference ranges might be preferred to fixed cut-offs in the estimation of umbilical cord acidemia at birth.

INTRODUCTION
In extremely and very preterm infants, predicting individual risks for adverse outcomes antenatally is challenging but necessary for risk-stratified perinatal management and parents' participation in decision-making about treatment. Our aim was to develop and validate prediction models for short-term (neonatal period) and medium-term (3 years of age) outcomes based on antenatal maternal and fetal factors alone.
MATERIAL AND METHODS
A population-based study was conducted on 31 157 neonates weighing ≤1500 g and born between 22 and 31 weeks of gestation registered in the Neonatal Research Network of Japan during 2006-2015. Short-term outcomes were assessed in 31 157 infants and medium-term outcomes were assessed in 13 751 infants among the 31 157 infants. The clinical data were randomly divided into training and validation data sets in a ratio of 2:1. The prediction models were developed by factors selected using stepwise logistic regression from 12 antenatal maternal and fetal factors with the training data set. The number of factors incorporated into the model varied from 3 to 10, on the basis of each outcome. To evaluate predictive performance, the area under the receiver operating characteristics curve (AUROC) was calculated for each outcome with the validation data set.
RESULTS
Among short-term outcomes, AUROCs for in-hospital death, chronic lung disease, intraventricular hemorrhage (grade III or IV) and periventricular leukomalacia were 0.85 (95% CI 0.83-0.86), 0.80 (95% CI 0.79-0.81), 0.78 (95% CI 0.75-0.80), and 0.58 (95% CI 0.55-0.61), respectively. Among medium-term outcomes, AUROCs for cerebral palsy and developmental quotient of <70 at 3 years of age were 0.66 (95% CI 0.63-0.69) and 0.72 (95% CI 0.70-0.74), respectively.
CONCLUSIONS
Although the predictive performance of these models varied for each outcome, their discriminative ability for in-hospital death, chronic lung disease, and intraventricular hemorrhage (grade III or IV) was relatively good. We provided a bedside prediction tool for calculating the likelihood of various infant complications for clinical use. To develop these prediction models would be valuable in each country, and these risk assessment tools could facilitate risk-stratified perinatal management and parents' shared understanding of their infants' subsequent risks.
