Meta-Analysis Review
India contributes the highest absolute number of stillbirths in the world. This systematic review and meta-analysis was conducted to synthesize the burden, timing and causes of stillbirths in India. Forty-nine reports from 46 studies conducted in 21 Indian states and Union Territories were included. It was found that there was no uniformity/standardization in the definition of stillbirths and in the classification system used to assign the cause. The share of antepartum stillbirths was estimated to be two-third while remaining were intrapartum stillbirths. Maternal conditions and fetal causes were found to be the leading cause of stillbirth in India. The maternal condition was assigned as the commonest cause (25%) followed by fetal (14%), placental cause (13%), congenital malformation (6%) and intrapartum complications (4%). Approximately 20% of the stillbirths were assigned as unknown or unexplained. This review demonstrates that there is a paucity of quality stillbirth data in India. Other than the state level differences in stillbirth rates, no other data is available on inequities in stillbirths in India. There is an urgent need for strengthening availability and quality of stillbirth data in India on both stillbirth rates as well as the causes. There is a need to conduct additional research to know the timing of the stillbirths, causes of death and actual burden. India needs to strengthen stillbirth audits along with registry to find out the modifiable factors and delays for making country specific preventive strategies. The policy makers, academic community and researchers need to work together to ensure accelerated and equitable reduction in stillbirths in India.

Induction of labour at 39 weeks and adverse outcomes in low-risk pregnancies according to ethnicity, socioeconomic deprivation, and parity: A national cohort study in England.
BACKGROUND
Ethnic and socioeconomic inequalities in obstetric outcomes are well established. However, the role of induction of labour (IOL) to reduce these inequalities is controversial, in part due to insufficient evidence. This national cohort study aimed to identify adverse perinatal outcomes associated with IOL with birth at 39 weeks of gestation ("IOL group") compared to expectant management ("expectant management group") according to maternal characteristics in women with low-risk pregnancies.
METHODS AND FINDINGS
All English National Health Service (NHS) hospital births between January 2018 and March 2021 were examined. Using the Hospital Episode Statistics (HES) dataset, maternal and neonatal data (demographic, diagnoses, procedures, labour, and birth details) were linked, with neonatal mortality data from the Office for National Statistics (ONS). Women with a low-risk pregnancy were identified by excluding pregnancies with preexisting comorbidities, previous cesarean section, breech presentation, placenta previa, gestational diabetes, or a baby with congenital abnormalities. Women with premature rupture of membranes, placental abruption, hypertensive disorders of pregnancy, amniotic fluid abnormalities, or antepartum stillbirth were excluded only from the IOL group. Adverse perinatal outcome was defined as stillbirth, neonatal death, or neonatal morbidity, the latter identified using the English composite neonatal outcome indicator (E-NAOI). Binomial regression models estimated risk differences (with 95% confidence intervals (CIs)) between the IOL group and the expectant management group, adjusting for ethnicity, socioeconomic background, maternal age, parity, year of birth, and birthweight centile. Interaction tests examined risk differences according to ethnicity, socioeconomic background, and parity. Of the 1 567 004 women with singleton pregnancies, 501 072 women with low-risk pregnancies and with sufficient data quality were included in the analysis. Approximately 3.3% of births in the IOL group (1 555/47 352) and 3.6% in the expectant management group (16 525/453 720) had an adverse perinatal outcome. After adjustment, a lower risk of adverse perinatal outcomes was found in the IOL group (risk difference -0.28%; 95% CI -0.43%, -0.12%; p = 0.001). This risk difference varied according to socioeconomic background from 0.38% (-0.08%, 0.83%) in the least deprived to -0.48% (-0.76%, -0.20%) in the most deprived national quintile (p-value for interaction = 0.01) and by parity with risk difference of -0.54% (-0.80%, -0.27%) in nulliparous women and -0.15% (-0.35%, 0.04%) in multiparous women (p-value for interaction = 0.02). There was no statistically significant evidence that risk differences varied according to ethnicity (p = 0.19). Key limitations included absence of additional confounding factors such as smoking, BMI, and the indication for induction in the HES datasets, which may mean some higher risk pregnancies were included.
CONCLUSIONS
IOL with birth at 39 weeks was associated with a small reduction in the risk of adverse perinatal outcomes, with 360 inductions in low-risk pregnancies needed to avoid 1 adverse outcome. The risk reduction was mainly present in women from more socioeconomically deprived areas and in nulliparous women. There was no significant risk difference found by ethnicity. Increased uptake of IOL at 39 weeks, especially in women from more socioeconomically deprived areas, may help reduce inequalities in adverse perinatal outcomes.

Background Fetal death is the delivery of a fetus with no sign of life, as indicated by the absence of breathing, heartbeat, pulsation of the umbilical cord, or definite movement of voluntary muscles. Nearly 2.6 million stillbirths are estimated to occur worldwide every year. Almost all of these (98%) stillbirths occur in low- and middle-income countries. About one-sixth of the stillbirths globally were recorded in India in 2019, making it the most burdened country in the world. In light of this, we conducted a study to identify the placental pathologies and maternal factors associated with stillbirth. Methodology A case-control study was conducted at the Department of Obstetrics & Gynecology, Veer Surendra Sai Institute of Medical Sciences and Research (VIMSAR), from June 2022 to May 2023. Cases included pregnant women with a gestational age of 28 weeks or more who delivered a stillbirth infant at VIMSAR, and controls included gestational age-matched deliveries with live birth. Consent to participate in the study was obtained before enrolment. The final sample size was 79 cases and controls. The chi-square test was performed for bivariate analysis, and logistic regression was used for multivariate analysis. Results In our study, we found a significant association between maternal age of more than 30 years (odds ratio (OR) = 3.01, 95% confidence interval (CI) = 1.91-4.22, p = 0.012), maternal education (with up to the primary level or less: OR = 6.19, 95% CI = 2.92-7.87, p = 0.012), history of addiction (tobacco chewing: OR = 5.58, 95% CI = 3.71-7.11, p = 0.03), and the number of antenatal visits (no visit: OR = 6.87, 95% CI = 2.91-7.79, p = 0.019) with an increased risk of stillbirth. Among the obstetrical complications, pre-eclampsia/eclampsia (OR = 3.87, 95% CI = 1.98-5.11, p = 0.001), premature rupture of membranes (PROM)/preterm premature rupture of the membranes (PPROM) (OR = 2.49, 95% CI = 1.31-3.91, p = 0.03) and antepartum hemorrhage (APH) (OR = 2.66, 95% CI = 1.65-3.58, p = 0.02) were found to be significantly related with stillbirth. Among placental pathologies, uteroplacental vascular pathology (OR = 7.39, 95% CI = 3.01-8.97), acute chorioamnionitis (OR = 3.35, 95% CI = 2.11-5.21), chronic inflammation (OR = 2.33, 95% CI = 1.91 4.17), calcific changes (OR = 4.46, 95% CI = 2.56-6.01), and retroplacental clots (OR = 9.95, 95% CI = 4.39-11.71) were associated with stillbirth. Conclusions In our study, advanced maternal age, absence of antenatal visits, low level of education, tobacco addiction, pre-eclampsia/eclampsia, APH, and PROM in pregnancy were the major risk factors associated with stillbirth. Uteroplacental vascular pathology, chorioamnionitis, chronic inflammation, retroplacental hematoma, and calcific changes were the most significant placental lesions associated with stillbirth.

Review
BACKGROUND
Sub-Saharan African (SSA) countries have high stillbirth rates compared with high-income countries, yet research on risk factors for stillbirth in SSA remain scant.
OBJECTIVES
To identify the modifiable risk factors of stillbirths in SSA and investigate their strength of association using a systematic review.
SEARCH STRATEGY
CINAHL Plus, EMBASE, Global Health and MEDLINE databases were searched for literature.
SELECTION CRITERIA
Observational population- and facility-level studies exploring stillbirth risk factors, published in 2013-2019 were included.
DATA COLLECTION AND ANALYSIS
A narrative synthesis of data was undertaken and the potential risk factors were classified into subgroups.
MAIN RESULTS
Thirty-seven studies were included, encompassing 20 264 stillbirths. The risk factors were categorised as: maternal antepartum factors (0-4 antenatal care visits, multiple gestations, hypertension, birth interval of >3 years, history of perinatal death); socio-economic factors (maternal lower wealth index and basic education, advanced maternal age, grand multiparity of ≥5); intrapartum factors (direct obstetric complication); fetal factors (low birthweight and gestational age of <37 weeks) and health systems factors (poor quality of antenatal care, emergency referrals, ill-equipped facility). The proportion of unexplained stillbirths remained very high. No association was found between stillbirths and body mass index, diabetes, distance from the facility or HIV.
CONCLUSIONS
The overall quality of evidence was low, as many studies were facility based and did not adjust for confounding factors. This review identified preventable risk factors for stillbirth. Focused programmatic strategies to improve antenatal care, emergency obstetric care, maternal perinatal education, referral and outreach systems, and birth attendant training should be developed. More population-based, high-quality research is needed.

Changes in perinatal management and outcomes of extremely preterm infants born below 26 weeks of gestation in a tertiary referral hospital in Sweden: Comparison between 2004-2007 and 2012-2016.
INTRODUCTION
Perinatal management of extremely preterm births in Sweden has changed toward active care from 22-23 gestational weeks during the last decades. However, considerable regional differences exist. This study evaluates how one of the largest perinatal university centers has adapted to a more active care between 2004-2007 and 2012-2016 and if this has influenced infant survival.
MATERIAL AND METHODS
In this historical cohort study, women admitted with at least one live fetus and delivered at 22-25 gestational weeks (stillbirths included) at Karolinska University Hospital Solna during April 1, 2004-March 31, 2007, and January 1, 2012-December 31, 2016, were compared regarding rates of obstetric and neonatal interventions, and infant mortality and morbidity. Maternal, pregnancy and infant data from 2004-2007 were obtained from the Extreme Preterm Infants in Sweden Study while data from 2012-2016 were extracted from medical journals and quality registers. The same definitions of interventions and diagnoses were used for both study periods.
RESULTS
A total of 106 women with 118 infants during 2004-2007 and 213 women with 240 infants during 2012-2016 were included. Increases between the study periods were seen regarding cesarean delivery (overall rate 14% [17/118] during 2004-2007 vs. 45% [109/240] during 2012-2016), attendance of a neonatologist at birth (62% [73/118] vs. 85% [205/240]) and surfactant treatment at birth in liveborn infants (60% [45/75] vs. 74% [157/211]). Antepartum stillbirth rate decreased (13% [15/118] vs. 5% [12/240]) and the proportion of live births increased (80% [94/118] vs. 88% [211/240]) while 1-year survival (64% [60/94] vs. 67% [142/211]) and 1-year survival without major neonatal morbidity (21% [20/94] vs. 21% [44/211]) among liveborn infants did not change between the study periods. At 22 gestational weeks, interventions rates were still low during 2012-2016, most obvious regarding antenatal steroid treatment (23%), attendance of a neonatologist (51%), and intubation at birth (24%).
CONCLUSIONS
Both obstetric and neonatal interventions at births below 26 gestational weeks increased between 2004-2007 and 2012-2016 in this single center study; however, at 22 gestational weeks they were still at a low level during 2012-2016. Despite more infants being born alive, 1-year survival did not increase between the study periods.

INTRODUCTION
Ethiopia is one of the countries facing a very high burden of perinatal death in the world. Despite taking several measures to reduce the burden of stillbirth, the pace of decline was not that satisfactory. Although limited perinatal mortality studies were conducted at a national level, none of the studies stressed the timing of perinatal death. Thus, this study is aimed at determining the magnitude and risk factors that are associated with the timing of perinatal death in Ethiopia.
METHODS
National perinatal death surveillance data were used in the study. A total of 3814 reviewed perinatal deaths were included in the study. Multilevel multinomial analysis was employed to examine factors associated with the timing of perinatal death in Ethiopia. The final model was reported through the adjusted relative risk ratio with its 95% Confidence Interval, and variables with a p-value less than 0.05 were declared statistically significant predictors of the timing of perinatal death. Finally, a multi-group analysis was carried out to observe inter-regional variation among selected predictors.
RESULT
Among the reviewed perinatal deaths, 62.8% occurred during the neonatal period followed by intrapartum stillbirth, unknown time of stillbirth, and antepartum stillbirth, each contributing 17.5%,14.3%, and 5.4% of perinatal deaths, respectively. Maternal age, place of delivery, maternal health condition, antennal visit, maternal education, cause of death (infection and congenital and chromosomal abnormalities), and delay to decide to seek care were individual-level factors significantly associated with the timing of perinatal death. While delay reaching a health facility, delay to receive optimal care health facility, type of health facility and type region were provincial-level factors correlated with the timing of perinatal death. A statistically significant inter-regional variation was observed due to infection and congenital anomalies in determining the timing of perinatal death.
CONCLUSION
Six out of ten perinatal deaths occurred during the neonatal period, and the timing of perinatal death was determined by neonatal, maternal, and facility factors. As a way forward, a concerted effort is needed to improve the community awareness of institutional delivery and ANC visit. Moreover, strengthening the facility level readiness in availing quality service through all paths of the continuum of care with special attention to the lower-level facilities and selected poor-performing regions is mandatory.

Observational Study
Background Intrauterine fetal death (IUFD) is a demise occurring at 20 or more weeks of gestation and weight 500 gram or more. Intrauterine fetal death at any point during gestation is a traumatic event not only to the patient but also to the care giver. The purpose of this study is to know the risk factors associated with intrauterine fetal death. Objective To determine the factors associated with intrauterine fetal death. Method Prospective observational study was conducted at Paropkar maternity women's hospital, Thapathali, Kathmandu. All the cases with intrauterine fetal death were admitted and delivered in the hospital with period of gestation 20 weeks to term pregnancy. All the relevant data were recorded in pre-designed proforma. The collected data were entered in SPSS 25 version for analysis. Result There was a total 5153 deliveries in three months, with prevalence of 1.2% and intrauterine rate of 12.03 per 1000 births. Out of 50 enrolled cases, 78% (n=50) of patient had not attended antenatal checkup. Majority (n=50; 74%), belonged to age group 21-35 years, 48% of intrauterine fetal death were term pregnancies of 37 to 42 weeks of gestation. Maximum 20% of IUFD, weighed between (1-1.5 kg) (1.5-2 kg) and (2.5-3 kg). Thirty-nine babies were macerated and eleven non-macerated. Pregnancy induced hypertension was most common (26%), followed by ante-partum hemorrhage (8%), hypothyroidism and anemia (6%), meconium stained liquor and cord prolapse (6%), gestational diabetes mellitus, congenital anomalies, chronic hypertension (4%), intrauterine growth restriction and urinary tract infection (2%). Twelve cases underwent cesarean section. Postpartum complications were found in 10 cases; 4 cases had postpartum hemorrhage, 4 had prolonged hospital stay and 2 cases developed hemolysis, elevated liver enzyme, low platelet count (HELLP) syndrome. Conclusion This study concluded that maximum no. of intrauterine fetal death were seen antenatally, as 78% of cases were found macerated. The commonest identified risk factor was pregnancy induced hypertension, followed by ante-partum hemorrhage, anemia, hypothyroidism, which seem to be preventable risk factors of intrauterine fetal death, but still unidentified risk factors are of great challenges for the obstetricians.

BACKGROUND
Antepartum stillbirth is a public health problem in a low-income country like Ethiopia. Quality antenatal care (ANC) is supposed to reduce the risk of many bad outcomes. Thus the main objective of this study was to identify the effect of quality antenatal care on antepartum stillbirth in Public health facilities of Hossana town Hadiya zone south Ethiopia.
METHOD
About 1123 mothers with a gestational age of less than 16 weeks were identified and followed using an observational longitudinal study to determine whether the quality of ANC influences antepartum stillbirth or not. Standardized and pretested observation checklists and participants' interview questionnaires were employed to obtain the necessary information after getting both written and verbal consent from the concerned bodies and study participants. In this study, quality was measured by the process attributes of quality to measure the acceptable standard of quality of antenatal care. Women who received ≥75% of essential ANC services (from 1st-4th visit) were categorized under received good quality antenatal care. General estimating equation analysis was done to determine the effect of quality antenatal care on antepartum stillbirth.
RESULT
A total of 121 (12.3%) 95% CI (10.3%, 14.5%) mothers who were observed during delivery had encountered antepartum stillbirth. In this study, the overall quality of antenatal care service that was provided in the whole visit (1st -4th) was 1230 (31.38%). Higher quality ANC decreases the odds of antepartum stillbirth by almost 81%, after controlling other factors (0.19 (AOR 0.19 at 95% CI; 0.088 to 0.435). There is a change in the odds of developing antepartum stillbirth as the level of education of mothers increases. Moreover, mothers with a history of preexisting hypertension were more like to have antepartum stillbirth AOR = 3.1, 95%CI (1.44, 6.77)].
CONCLUSION AND RECOMMENDATION
Therefore, having a good quality of ANC significantly reduces antepartum stillbirth. Strategies need to be developed on the problems identified to improve the quality of ANC and reduce antepartum stillbirth significantly.

Turkish Journal of Obstetrics and... Mar 2023To assess whether antenatal azithromycin given to pregnant women with vaginal cerclage can reduce preterm birth or not.
OBJECTIVE
To assess whether antenatal azithromycin given to pregnant women with vaginal cerclage can reduce preterm birth or not.
MATERIALS AND METHODS
We randomized 50 pregnant ladies who underwent cerclage at Ain Shams University Maternity Hospital in group A (receiving 500 mg Azithromycin oral tablets (Zithrokan, Hikma, Egypt) one tablet orally twice daily for three days in 3 courses at 14, 24 and 32 week, plus usual antenatal care) and an identical group B (receiving usual antenatal care). Our primary outcome was gestational age at delivery, and secondary outcomes were birthweight, mode of delivery, and maternal, and perinatal complications. This study was registered on ClinicalTrials.gov with number: NCT04278937.
RESULTS
Pregnancy was more prolonged in the Azithromycin group (delivery at 36.8 weeks vs 34.1 weeks; p=0.017). Also, a higher birthweight was observed in the Azithromycin group (2932.6 gm vs 2401.8 gm; p=0.006). No significant difference was found between the two groups as regards to other outcomes (miscarriage, stillbirth, neonatal intensive care unit admission, antepartum hemorrhage, postpartum pyrexia, need for blood transfusion).
CONCLUSION
Adding antenatal azithromycin to women undergoing cerclage prolongs pregnancy and reduces the risk of preterm birth, with a slight increase in birthweight.

Patients at increased risk of stillbirth should be assessed with antepartum fetal surveillance (AFS) tests at regular intervals. In general, AFS should begin at the gestational age at which delivery would be considered. Most surveillance tests are performed weekly, but more frequent testing should be considered for patients with high-risk conditions. AFS tests include fetal movement monitoring, nonstress test, contraction stress test, biophysical profile, and modified biophysical profile. Umbilical artery Doppler velocimetry is used in the setting of fetal growth restriction. Abnormal test results should prompt additional assessment and consideration of delivery. Normal test results can provide reassurance about fetal well-being, but cannot predict the likelihood of acute incidents, such as placental abruption and umbilical cord infarction.
