American Journal of Obstetrics &... Mar 2022As a vulnerable population, pregnant women with a substance-related diagnosis (ie, substance use, misuse, or dependence) may use healthcare disproportionately.
BACKGROUND
As a vulnerable population, pregnant women with a substance-related diagnosis (ie, substance use, misuse, or dependence) may use healthcare disproportionately.
OBJECTIVE
The primary goal of this study was to evaluate the differences in the use of outpatient clinical visits, emergency department visits, and inpatient days in the hospital among women with and without a substance-related diagnosis during the antepartum period.
STUDY DESIGN
This retrospective study retrieved electronic health record data on women (age, 18-44 years) who delivered a single live birth or stillbirth at ≥20 weeks of gestation from April 1, 2012, to September 30, 2019. Imbalance in measured maternal sociodemographic and obstetrical characteristics between women with and without a substance-related diagnosis was attenuated using propensity score matching on key demographic characteristics (eg, age), yielding a matched 1:1 sample. Unadjusted and adjusted logistic regressions models were used to determine the association between a substance-related diagnosis and outpatient visits, emergency visits, and inpatient days.
RESULTS
From the total sample (n=16,770), the matched cohort consisted of 1986 deliveries. Of these, most were White (51.0%), or mixed or of some other race (31.1%). The mean age was 29.8 (standard deviation, 5.6). A substance-related diagnosis was identified in 993 women (50%) because of matching. Women with a substance-related diagnosis were more likely to have ≤10 outpatient visits than women without a substance-related diagnosis (adjusted odds ratio, 1.81 [95% confidence interval, 1.44-2.28]; P<.0001). Alcohol-, opioid-, and stimulant-related diagnoses were independently associated with ≤10 outpatient visits (adjusted odds ratio, 3.16 [95% confidence interval, 1.67-6.04]; P=.0005; adjusted odds ratio, 3.02 [95% confidence interval, 1.79-5.09]; P<.0001; adjusted odds ratio, 2.18 [95% confidence interval, 1.39-3.41]; P=.0007, respectively). Women with a substance-related diagnosis were more likely to have ≥1 emergency visit than women without a substance-related diagnosis (adjusted odds ratio, 1.36 [95% confidence interval, 1.00-1.85]; P<.0001). Opioid-, stimulant-, and nicotine-related diagnoses were independently associated with ≥1 emergency visit (adjusted odds ratio, 2.28 [95% confidence interval, 1.09-4.77]; P=.0287; adjusted odds ratio, 2.01 [95% confidence interval, 1.07-3.78]; P=.0301; adjusted odds ratio, 3.38 [95% confidence interval, 1.90-6.02]; P<.0001, respectively). Women with a substance-related diagnosis were more likely to have ≥3 inpatient days than women without a substance-related diagnosis (adjusted odds ratio, 1.69 [95% confidence interval, 1.07-2.67]; P=.0256). Opioid-, stimulant-, and nicotine-related diagnosis were independently associated with ≥3 inpatient days (adjusted odds ratio, 3.52 [95% confidence interval, 1.42-8.75]; P=.0067; adjusted odds ratio, 3.51 [95% confidence interval, 1.31-9.34]; P=.0123; adjusted odds ratio, 2.74 [95% confidence interval, 1.11-6.73]; P=.0285, respectively).
CONCLUSION
Women with a substance-related diagnosis during the antepartum period who delivered a single live birth or stillbirth at ≥20 weeks of gestation were experiencing fewer outpatient visits, more emergency department visits, and more inpatient days than women without a substance-related diagnosis. The type of substance-related diagnosis (eg, alcohol, opioids, stimulants, or nicotine) was associated with different patterns of healthcare use. The results from this study have reinforced the need to identify substance-related diagnoses in pregnant women early to minimize disproportionate healthcare service utilization through intervention and treatment.

BACKGROUND
Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with increased risk of adverse perinatal health outcomes, few large-scale, community-based epidemiological studies have been conducted.
METHODS
We conducted a national cohort study using deidentified administrative claims data for 78 283 pregnancies with estimated conception before 30 April 2020 and pregnancy end after 11 March 2020. We identified SARS-CoV-2 infections using diagnostic and laboratory testing data, and compared the risk of pregnancy outcomes using Cox proportional hazard models treating coronavirus disease 2019 (COVID-19) as a time-varying exposure and adjusting for baseline covariates.
RESULTS
Of the pregnancies, 2655 (3.4%) had a documented SARS-CoV-2 infection. COVID-19 during pregnancy was not associated with risk of miscarriage, antepartum hemorrhage, or stillbirth, but was associated with 2-3 fold higher risk of induced abortion (adjusted hazard ratio [aHR], 2.60; 95% confidence interval [CI], 1.17-5.78), cesarean delivery (aHR, 1.99; 95% CI, 1.71-2.31), clinician-initiated preterm birth (aHR, 2.88; 95% CI, 1.93-4.30), spontaneous preterm birth (aHR, 1.79; 95% CI, 1.37-2.34), and fetal growth restriction (aHR, 2.04; 95% CI, 1.72-2.43).
CONCLUSIONS
Prenatal SARS-CoV-2 infection was associated with increased risk of adverse pregnancy outcomes. Prevention could have fetal health benefits.

(1) Background: Across Europe, the incidence of antepartum stillbirth varies greatly, partly because of heterogeneous definitions regarding gestational weeks and differences in legislation. With this study, we sought to provide a comprehensive overview on the demographics of antepartum stillbirth in Austria, defined as non-iatrogenic fetal demise ≥22 gestational weeks (/40). (2) Methods: We conducted a population-based study on epidemiological characteristics of singleton antepartum stillbirth in Austria between January 2008 and December 2020. Data were derived from the validated Austrian Birth Registry. (3) Results: From January 2008 through December 2020, the antepartum stillbirth rate ≥20/40 was 3.10, ≥22/40 3.14, and ≥24/40 2.83 per 1000 births in Austria. The highest incidence was recorded in the federal states of Vienna, Styria, and Lower and Upper Austria, contributing to 71.9% of all stillbirths in the country. In the last decade, significant fluctuations in incidence were noted: from 2011 to 2012, the rate significantly declined from 3.40 to 3.07‰, whilst it significantly increased from 2.76 to 3.49‰ between 2019 and 2020. The median gestational age of antepartum stillbirth in Austria was 33 (27-37) weeks. Stillbirth rates ≤26/40 ranged from 164.98 to 334.18‰, whilst the lowest rates of 0.58-8.4‰ were observed ≥36/40. The main demographic risk factors were maternal obesity and low parity. (4) Conclusions: In Austria, the antepartum stillbirth rate has remained relatively stable at 2.83-3.10 per 1000 births for the last decade, despite a significant decline in 2012 and an increase in 2020.

Comparative Study
This study aimed to analyze the distribution of stillbirths by birth weight, type of death, the trend of Stillbirth Rate (SBR), and avoidable causes of death, according to social vulnerability clusters in São Paulo Municipality, 2007-2017. Social vulnerability clusters were created with the k-means method. The Prais-Winsten generalized linear regression was used in the trend of SBR by < 2500 g, ≥ 2500 g, and total deaths analysis. The Brazilian list of avoidable causes of death was adapted for stillbirths. There was a predominance of antepartum stillbirths (70%). There was an increase in SBR with the growth of social vulnerability from the center to the outskirts of the city. The cluster with the highest vulnerability presented SBR 69% higher than the cluster with the lowest vulnerability. SBR ≥ 2500 g was decreasing in the clusters with the high vulnerability. There was an increase in SBR of avoidable causes of death of the cluster from the lowest to the highest vulnerability. Ill-defined causes of death accounted for 75% of deaths in the highest vulnerability area. Rates of fetal mortality and avoidable causes of death increased with social vulnerability. The trend of reduction of SBR ≥ 2500 g may suggest improvement in prenatal care in areas of higher vulnerability.

BACKGROUND
Smoking is one of the modifiable risk factors for adverse maternal and neonatal outcomes and is associated with low birth weight, preterm birth, respiratory, antepartum and intrapartum stillbirth, and perinatal death as well as long-term morbidity in offspring and sudden unexpected infant death. The rate of smoking in low- and middle-income countries is still relevantly high, and Jordan is no exception.
OBJECTIVE
To investigate the effect of active and passive smoking during pregnancy on adverse pregnancy outcomes.
METHODS
The case-control study was conducted in Jordan in June 2020. Healthy women with full-term singleton pregnancy (n = 180) were interviewed and stratified into three groups: Group I, active smokers; Group II, passive smokers; and Group III, nonsmokers. The study variables included demographic data, current pregnancy history, cotinine level of mothers and newborns, and perinatal outcomes. Statistical analysis was performed using the application package IBM SPSS 25. Various algorithms of statistical analysis were used depending on the type of distribution of feature and data quality. The threshold for statistical significance was set at < 0.05.
RESULTS
Active smokers had significantly lower gestational age at delivery compared to passive and nonsmoking women ( = 0.038 and = 0.003, respectively). Neonates from active smoking mothers had significantly lower birth weight compared to neonates from passive and nonsmoking women ( = 0.016 and = 0.019, respectively), significantly lower head and chest circumferences compared to babies from passive smokers ( < 0.001 and = 0.036, respectively), and significantly lower first-minute Apgar score compared to those from nonsmoking women ( = 0.023). The urine cotinine level was significantly higher in both active and passive smoking women (both < 0.01), and it was significantly higher in newborns who had been exposed to smoking in utero despite maternal active or passive smoking status (both < 0.001). There was a weak negative correlation between urine cotinine level and birth weight: = -0.14 for maternal cotinine level and = -0.15 for neonate cotinine level.
CONCLUSIONS
The current study illustrated that smoking during pregnancy leads to offspring with reduced birth weight, birth length, and head and chest circumference; reduces delivery gestational age; and lowers the first-minute Apgar score. Our study findings highlight the need for further research issued to smoking effects on perinatal outcomes, the implementation of actions to develop cessation interventions in the preconception period, and an evaluation of useful interventions to enhance a smoking-free environment during pregnancy.

To investigate whether earlier "post-term" monitoring of South Asian (SA) pregnancies from 39 weeks' gestation with amniotic fluid index (AFI) and cardiotocography (CTG) detected suspected fetal compromise. Retrospective cohort study of all SA-born women at an Australian health service with uncomplicated, singleton pregnancies following the introduction of twice-weekly AFI and CTG monitoring from 39 weeks. Monitoring results, and their association with a perinatal compromise composite (including assisted delivery for fetal compromise, stillbirth, and NICU admission) were determined. 771 SA-born women had earlier monitoring, triggering delivery in 82 (10.6%). 31 (4%) had a non-reassuring antepartum CTG (abnormal fetal heart rate or variability, or decelerations) and 21 (2.7%) had an abnormal AFI (≤ 5 cm). Women with abnormal monitoring were 53% (95% CI 1.2-1.9) more likely to experience perinatal compromise and 83% (95% CI 1.2-2.9) more likely to experience intrapartum compromise than women with normal monitoring. Monitoring from 39 weeks identified possible fetal compromise earlier than it otherwise would have been, and triggered intervention in 10% of women. Without robust evidence to guide timing of birth in SA-born women to reduce rates of stillbirth, earlier monitoring provides an alternative to routine induction of labour.

BMJ Open Nov 2021To describe the epidemiology of uterine rupture in China from 2015 to 2016 and to build a prediction model for uterine rupture in women with a scarred uterus.
OBJECTIVES
To describe the epidemiology of uterine rupture in China from 2015 to 2016 and to build a prediction model for uterine rupture in women with a scarred uterus.
SETTING
A multicentre cross-sectional survey conducted in 96 hospitals across China in 2015-2016.
PARTICIPANTS
Our survey initially included 77 789 birth records from hospitals with 1000 or more deliveries per year. We excluded 2567 births less than 24 gestational weeks or unknown and 1042 births with unknown status of uterine rupture, leaving 74 180 births for the final analysis.
PRIMARY AND SECONDARY OUTCOME MEASURES
Complete and incomplete uterine rupture and the risk factors, and a prediction model for uterine rupture in women with scarred uterus (assigned each birth a weight based on the sampling frame).
RESULTS
The weighted incidence of uterine rupture was 0.18% (95% CI 0.05% to 0.23%) in our study population during 2015 and 2016. The weighted incidence of uterine rupture in women with scarred and intact uterus was 0.79% (95% CI 0.63% to 0.91%) and 0.05% (95% CI 0.02% to 0.13%), respectively. Younger or older maternal age, prepregnancy diabetes, overweight or obesity, complications during pregnancy (hypertensive disorders in pregnancy and gestational diabetes), low education, repeat caesarean section (≥2), multiple abortions (≥2), assisted reproductive technology, placenta previa, induce labour, fetal malpresentation, multiple pregnancy, anaemia, high parity and antepartum stillbirth were associated with an increased risk of uterine rupture. The prediction model including eight variables (OR >1.5) yielded an area under the curve (AUC) of 0.812 (95% CI 0.793 to 0.836) in predicting uterine rupture in women with scarred uterus with sensitivity and specificity of 77.2% and 69.8%, respectively.
CONCLUSIONS
The incidence of uterine rupture was 0.18% in this population in 2015-2016. The predictive model based on eight easily available variables had a moderate predictive value in predicting uterine rupture in women with scarred uterus. Strategies based on predictions may be considered to further reduce the burden of uterine rupture in China.

BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 has had dramatic effects on the pregnant population worldwide, increasing the risk of adverse perinatal outcomes.
OBJECTIVE
To assess the incidence of antepartum stillbirth (aSB) during the COVID-19 pandemic in Austria.
METHODS
We collected epidemiological data from the Austrian Birth Registry and compared the rate of aSB (i.e., fetal death at or after 24 gestational weeks) during the pandemic period (March-December 2020) and in the respective pre-pandemic months (2015-2019).
RESULTS
In total, 65 660 pregnancies were included, of which 171 resulted in aSB at 33.7 ± 4.8 gestational weeks. During the pandemic, the aSB rate increased from 2.49‰ to 2.60‰ (P = 0.601), in contrast to the significant decline in preterm deliveries at or before 37 gestational weeks from 0.61‰ to 0.56‰ (relative risk [RR] 0.93; 95% confidence interval [CI] 0.91-0.96; P < 0.001). During the first lockdown, the aSB rate significantly increased from 2.38‰ to 3.52‰ (P = 0.021), yielding an adjusted odds ratio of 1.57 (95% CI 1.08-2.27; P = 0.018). The event of aSB during the COVID-19 pandemic was strongly related with increased fetal weight and maternal obesity.
CONCLUSION
In Austria, there has been an overall increase in the incidence of aSB during the pandemic with a significant peak during the first lockdown.

Ultrasound in Obstetrics & Gynecology :... Jan 2022To examine the performance of a model combining maternal risk factors, uterine artery pulsatility index (UtA-PI) and estimated fetal weight (EFW) at 19-24 weeks'...
Development and validation of model for prediction of placental dysfunction-related stillbirth from maternal factors, fetal weight and uterine artery Doppler at mid-gestation.
OBJECTIVE
To examine the performance of a model combining maternal risk factors, uterine artery pulsatility index (UtA-PI) and estimated fetal weight (EFW) at 19-24 weeks' gestation, for predicting all antepartum stillbirths and those due to impaired placentation, in a training dataset used for development of the model and in a validation dataset.
METHODS
The data for this study were derived from prospective screening for adverse obstetric outcome in women with singleton pregnancy attending for routine pregnancy care at 19 + 0 to 24 + 6 weeks' gestation. The study population was divided into a training dataset used to develop prediction models for placental dysfunction-related antepartum stillbirth and a validation dataset to which the models were then applied. Multivariable logistic regression analysis was used to develop a model based on a combination of maternal risk factors, EFW Z-score and UtA-PI multiples of the normal median. We examined the predictive performance of the model by, first, the ability of the model to discriminate between the stillbirth and live-birth groups, using the area under the receiver-operating-characteristics curve (AUC) and the detection rate (DR) at a fixed false-positive rate (FPR) of 10%, and, second, calibration by measurements of calibration slope and intercept.
RESULTS
The study population of 131 514 pregnancies included 131 037 live births and 477 (0.36%) stillbirths. There are four main findings of this study. First, 92.5% (441/477) of stillbirths were antepartum and 7.5% (36/477) were intrapartum, and 59.2% (261/441) of antepartum stillbirths were observed in association with placental dysfunction and 40.8% (180/441) were unexplained or due to other causes. Second, placental dysfunction accounted for 80.1% (161/201) of antepartum stillbirths at < 32 weeks' gestation, 54.2% (52/96) at 32 + 0 to 36 + 6 weeks and 33.3% (48/144) at ≥ 37 weeks. Third, the risk of placental dysfunction-related antepartum stillbirth increased with increasing maternal weight and decreasing maternal height, was 3-fold higher in black than in white women, was 5.5-fold higher in parous women with previous stillbirth than in those with previous live birth, and was increased in smokers, in women with chronic hypertension and in parous women with a previous pregnancy complicated by pre-eclampsia and/or birth of a small-for-gestational-age baby. Fourth, in screening for placental dysfunction-related antepartum stillbirth by a combination of maternal risk factors, EFW and UtA-PI in the validation dataset, the DR at a 10% FPR was 62.3% (95% CI, 57.2-67.4%) and the AUC was 0.838 (95% CI, 0.799-0.878); these results were consistent with those in the dataset used for developing the algorithm and demonstrate high discrimination between affected and unaffected pregnancies. Similarly, the calibration slope was 1.029 and the intercept was -0.009, demonstrating good agreement between the predicted risk and observed incidence of placental dysfunction-related antepartum stillbirth. The performance of screening was better for placental dysfunction-related antepartum stillbirth at < 37 weeks' gestation compared to at term (DR at a 10% FPR, 69.8% vs 29.2%).
CONCLUSIONS
Screening at mid-gestation by a combination of maternal risk factors, EFW and UtA-PI can predict a high proportion of placental dysfunction-related stillbirths and, in particular, those that occur preterm. Such screening provides poor prediction of unexplained stillbirth or stillbirth due to other causes. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

BACKGROUND
Abortion and stillbirths are the common obstetrics condition in Ethiopia and their effect on the next pregnancy was not well identified in resource limited settings. The aim of the study was to assess the effect of stillbirth and abortion on the next pregnancy.
METHODS
A prospective cohort study design was implemented. The study was conducted in Mecha demographic surveillance and field research center catchment areas. The data were collected from January 2015 to March 2019. Epi-info software was used to calculate the sample size. The systematic random sampling technique was used to select stillbirth and abortion women. Poison regression was used to identify the predictors of MCH service utilization; descriptive statistics were used to identify the prevalence of blood borne pathogens. The Kaplan Meier survival curve was used to estimate survival to pregnancy and pregnancy related medical disorders.
RESULTS
1091 stillbirth and 3,026 abortion women were followed. Hepatitis B was present in 6% of abortion and 3.2% of stillbirth women. Hepatitis C was diagnosed in 4.7% of abortion and 0.3% of stillbirth women. HIV was detected in 3% of abortion and 0.8% of stillbirth women. MCH service utilization was determined by knowledge of contraceptives [IRR 1.29, 95% CI 1.18-1.42], tertiary education [IRR 4.29, 95% CI 3.72-4.96], secondary education. [IRR 3.14, 95% CI 2.73-3.61], married women [IRR 2.08, 95% CI 1.84-2.34], family size [IRR 0.67, 95% CI 1.001-1.01], the median time of pregnancy after stillbirth and abortion were 12 months. Ante-partum hemorrhage was observed in 23.1% of pregnant mothers with a past history of abortion cases and post-partum hemorrhage was observed in 25.6% of pregnant mothers with a past history of abortion. PREGNANCY INDUCED DIABETES MELLITUS was observed 14.3% of pregnant mothers with a past history of stillbirth and pregnancy-induced hypertension were observed in 9.2% of mothers with a past history of stillbirth.
CONCLUSION
Obstetric hemorrhage was the common complications of abortion women while Pregnancy-induced diabetic Mellitus and pregnancy-induced hypertension were the most common complications of stillbirth for the next pregnancy.
