BACKGROUND
In 2015, Nigeria's estimated 317,700 stillbirths accounted for 12.2% of the 2.6 million estimated global stillbirths. This suggests that Nigeria still makes substantial contribution to the global burden of stillbirths. This study was conducted to determine the prevalence and identify the causes and factors associated with stillbirth in eight referral hospitals in Nigeria.
METHODS
This was a cross-sectional study of all deliveries over a period of 6 months in six general hospitals (4 in the south and 2 in the north), and two teaching hospitals (both in the north) in Nigeria. The study population was women delivering in the hospitals during the study period. A pre-tested study protocol was used to obtain clinical data on pregnancies, live births and stillbirths in the hospitals over a 6 months period. Data were analyzed centrally using univariate, bivariate and multivariate logistic regression analyses. The main outcome measure was stillbirth rate in the hospitals (individually and overall).
RESULTS
There were 4416 single births and 175 stillbirths, and a mean stillbirth rate of 39.6 per 1000 births (range: 12.7 to 67.3/1000 births) in the hospitals. Antepartum (macerated) constituted 22.3% of the stillbirths; 47.4% were intrapartum (fresh stillbirths); while 30.3% was unclassified. Acute hypoxia accounted for 32.6% of the stillbirths. Other causes were maternal hypertensive disease (6.9%), and intrapartum unexplained (5.7%) among others. After adjusting for confounding variables, significant predictors of stillbirth were referral status, parity, past experience of stillbirth, birth weight, gestational age at delivery and mode of delivery.
CONCLUSION
We conclude that the rate of stillbirth is high in Nigeria's referral hospitals largely because of patients' related factors and the high rates of pregnancy complications. Efforts to address these factors through improved patients' education and emergency obstetric care would reduce the rate of stillbirth in the country.

Background Stillbirth often remains unexplained, mostly due to a lack of any postmortem examination or one that is incomplete and misinterpreted. Methods This retrospective cohort study was conducted at the Department of Obstetrics and Gynecology, Helsinki University Hospital, Finland, and comprised 214 antepartum singleton stillbirths from 2003 to 2015. Maternal and fetal characteristics and the results of the systematic postmortem examination protocol were collected from medical records. Causes of death were divided into 10 specific categories. Re-evaluation of the postmortem examination results followed. Results Based on our systematic protocol, the cause of death was originally defined and reported as such to parents in 133 (62.1%) cases. Re-evaluation of the postmortem examination results revealed the cause of death in an additional 43 (20.1%) cases, with only 23 (10.7%) cases remaining truly unexplained. The most common cause of stillbirth was placental insufficiency in 56 (26.2%) cases. A higher proportion of stillbirths that occurred at ≥39 gestational weeks remained unexplained compared to those that occurred earlier (24.1% vs. 8.6%) (P = 0.02). Conclusion A standardized postmortem examination and a re-evaluation of the results reduced the rate of unexplained stillbirth. Better knowledge of causes of death may have a major impact on the follow-up and outcome of subsequent pregnancies. Also, closer examination and better interpretation of postmortem findings is time-consuming but well worth the effort in order to provide better counseling for the grieving parents.

Stillbirth rates and their determinants in a national maternity hospital in Phnom Penh, Cambodia in 2017-2020: a cross-sectional assessment with a nested case-control study.
BACKGROUND
In Cambodia, stillbirths and their underlying factors have not been systematically studied. This study aimed to assess the proportion and trends in stillbirths between 2017 and 2020 in a large maternity referral hospital in the country and identify their key determinants to inform future prevention efforts.
METHODS
This was a retrospective cross-sectional analysis with a nested case-control study of women giving birth at the National Maternal and Child Health Centre (NMCHC) in Phnom Penh, 2017-2020. We calculated percentages of singleton births at ≥ 22 weeks' gestation resulting in stillbirth and annual stillbirth rates by timing: intrapartum (fresh) or antepartum (macerated). Multivariable logistic regression was used to explore factors associated with stillbirth, where cases were all women who gave birth to a singleton stillborn baby in the 4-year period. One singleton live birth immediately following each case served as an unmatched control. Multiple imputation was used to handle missing data for gestational age.
RESULTS
Between 2017 and 2020, 3.2% of singleton births ended in stillbirth (938/29,742). The stillbirth rate increased from 24.8 per 1000 births in 2017 to 38.1 per 1000 births in 2020, largely due to an increase in intrapartum stillbirth rates which rose from 18.8 to 27.4 per 1000 births in the same period. The case-control study included 938 cases (stillbirth) and 938 controls (livebirths). Factors independently associated with stillbirth were maternal age ≥ 35 years compared to < 20 years (aOR: 1.82, 95%CI: 1.39, 2.38), extreme (aOR: 3.29, 95%CI: 2.37, 4.55) or moderate (aOR: 2.45, 95%CI: 1.74, 3.46) prematurity compared with full term, and small-for-gestational age (SGA) (aOR: 2.32, 1.71, 3.14) compared to average size-for-age. Breech/transverse births had nearly four times greater odds of stillbirth (aOR: 3.84, 95%CI: 2.78, 5.29), while caesarean section reduced the odds by half compared with vaginal birth (aOR: 0.50, 95%CI: 0.39, 0.64). A history of abnormal vaginal discharge increased odds of stillbirth (aOR: 1.42, 95%CI: 1.11, 1.81) as did a history of stillbirth (aOR: 3.08, 95%CI: 1.5, 6.5).
CONCLUSIONS
Stillbirth prevention in this maternity referral hospital in Cambodia requires strengthening preterm birth detection and management of SGA, intrapartum care, monitoring women with stillbirth history, management of breech births, and further investigation of high-risk referral cases.

Observational Study
BACKGROUND
Despite approximately 2.6 million stillbirths occurring annually, there is a paucity of systematic biological investigation and consequently knowledge on the causes of these deaths in low- and middle-income countries (LMICs). We investigated the utility of minimally invasive tissue sampling (MITS), placental examination, and clinical history, in attributing the causes of stillbirth in a South African LMIC setting.
METHODS
This prospective, observational pilot study undertook sampling of brain, lung, and liver tissue using core biopsy needles, blood and cerebrospinal fluid collection, and placental examination. Testing included microbial culture and/or molecular testing and tissue histological examination. The cause of death was determined for each case by an international panel of medical specialists and categorized using the World Health Organization's International Classification of Diseases, Tenth Revision application to perinatal deaths.
RESULTS
A cause of stillbirth was identifiable for 117 of 129 (90.7%) stillbirths, including an underlying maternal cause in 63.4% (n = 83) and an immediate fetal cause in 79.1% (n = 102) of cases. The leading underlying causes of stillbirth were maternal hypertensive disorders (16.3%), placental separation and hemorrhage (14.0%), and chorioamnionitis (10.9%). The leading immediate causes of fetal death were antepartum hypoxia (35.7%) and fetal infection (37.2%), including due to Escherichia coli (16.3%), Enterococcus species (3.9%), and group B Streptococcus (3.1%).
CONCLUSIONS
In this pilot, proof-of-concept study, focused investigation of stillbirth provided granular detail on the causes thereof in an LMIC setting, including provisionally highlighting the largely underrecognized role of fetal sepsis as a dominant cause.

Meta-Analysis
Schizophrenia pregnancies should be given greater health priority in the global health agenda: results from a large-scale meta-analysis of 43,611 deliveries of women with schizophrenia and 40,948,272 controls.
Women with schizophrenia and their newborns are at risk of adverse pregnancy, delivery, neonatal and child outcomes. However, robust and informative epidemiological estimates are lacking to guide health policies to prioritise and organise perinatal services. For the first time, we carried out a systematic review and meta-analysis to synthesise the accumulating evidence on pregnancy, delivery, neonatal complications, and infant mortality among women with schizophrenia and their newborns (N = 43,611) vs. controls (N = 40,948,272) between 1999 and 2021 (26 population-based studies from 11 high-income countries) using random effects. Women with schizophrenia had higher odds (OR) of gestational diabetes (2.35, 95% CI: [1.57-3.52]), gestational hypertension, pre-eclampsia/eclampsia (OR 1.55, 95% CI: [1.02-2.36]; 1.85, 95% CI: [1.52-2.25]), antepartum and postpartum haemorrhage (OR 2.28, 95% CI: [1.58-3.29]; 1.14, 95% CI: [1.04-1.24]), placenta abruption, threatened preterm labour, and premature rupture of membrane (OR 2.20, 95% CI: [2.02-2.39]; 2.91, 95% CI: [1.57-5.40]; 1.29, 95% CI: [1.06-1.58]), c-section (OR 1.33, 95% CI: [1.22-1.45]), foetal distress (OR 1.80, 95% CI: [1.43-2.26]), preterm and very preterm delivery (OR 1.79, 95% CI: [1.62-1.98]; 2.31, 95% CI: [1.78-2.98]), small for gestational age and low birth weight (OR 1.63, 95% CI: [1.48-1.80]; 1.75, 95% CI: [1.46-2.11]), congenital malformations (OR 1.86, 95% CI: [1.71-2.03]), and stillbirths (OR 2.06, 95% CI: [1.83-2.31]). Their newborns had higher odds of neonatal death (OR 1.41, 95% CI: [1.03-1.94]), post-neonatal death (OR 2.87, 95% CI: [2.11-3.89]) and infant mortality (OR 2.33, 95% CI: [1.81-3.01]). This large-scale meta-analysis confirms that schizophrenia is associated with a substantially increased risk of very preterm delivery, stillbirth, and infant mortality, and metabolic risk in mothers. No population-based study has been carried out in low- and middle-income countries in which health problems of women with schizophrenia are probably more pronounced. More research is needed to better understand the complex needs of women with schizophrenia and their newborns, determine how care delivery could be optimised, and define best practices.

OBJECTIVE
Molar pregnancy coexistent with a live fetus can be a diagnostic and therapeutic challenge. With increasing incidence of multiple pregnancies, there has also been an increase in twin pregnancy with one mole in the recent years. The authors discuss the epidemiology, clinical presentation, and prenatal diagnosis and attempt to design a possible management strategy, to help guide the treating physician, in the management of partial mole with live pregnancy, thereby improving maternal and fetal prognosis.
MATERIAL AND METHODS
Numerous case reports have been published in various journals regarding management of individual cases of partial molar pregnancy coexistent with live fetus (PMCF). Therefore, we conducted a systematic review of all the case reports and short case series in English concerning partial mole with live pregnancy from 1999 to 2019, that is in the last 20 years.
RESULTS
In total, 44 case reports of PMCF were analyzed. The mean gestational age at diagnosis was 20+6 (range: 10-40) weeks. Less than half (19/44; 43.2%) were asymptomatic at the time of detection and PMCF was detected on routine scan done for fetal well-being or 11-13-week scan. The majority (56.8%) resulted in the birth of a healthy live fetus. Gestational trophoblastic neoplasia developed in 3/44 (6.8%).
CONCLUSION
PMCF involves a high risk of bleeding, preterm labour, intrauterine growth restriction and stillbirth. Successful management of such cases needs prenatal diagnosis, antepartum surveillance and post-natal follow-up. An obstetrician, maternal fetal medicine specialist, gynecology oncologist and neonatal intensivist should be involved in the care of such pregnancies.

Comparative Study
BACKGROUND
Malawi implemented a Results Based Financing (RBF) model for Maternal and Newborn Health, "RBF4MNH" at public hospitals in four Districts, with the aim of improving health outcomes. We used this context to seek evidence for the impact of this intervention on rates of antepartum and intrapartum stillbirth, taking women's risk factors into account.
METHODS
We used maternity unit delivery registers at hospitals in four districts of Malawi to obtain information about stillbirths. We purposively selected two districts hosting the RBF4MNH intervention and two non-intervention districts for comparison. Data were extracted from the maternity registers and used to develop logistic regression models for variables associated with fresh and macerated stillbirth.
RESULTS
We identified 67 stillbirths among 2772 deliveries representing 24.1 per 1000 live births of which 52% (n = 35) were fresh (intrapartum) stillbirths and 48% (n = 32) were macerated (antepartum) losses. Adjusted odds ratios (aOR) for fresh and macerated stillbirth at RBF versus non-RBF sites were 2.67 (95%CI 1.24 to 5.57, P = 0.01) and 7.27 (95%CI 2.74 to 19.25 P < 0.001) respectively. Among the risk factors examined, gestational age at delivery was significantly associated with increased odds of stillbirth.
CONCLUSION
The study did not identify a positive impact of this RBF model on the risk of fresh or macerated stillbirth. Within the scientific limitations of this non-randomised study using routinely collected health service data, the findings point to a need for rigorously designed and tested interventions to strengthen service delivery with a focus on the elements needed to ensure quality of intrapartum care, in order to reduce the burden of stillbirths.

Incidence of Stillbirth in Relation to Period of Delivery, Socioeconomic Status and Period of Gestation in a Rural Tertiary Care Hospital-MGIMS, Sewagram Within Study Period of Three Years (2013-2016).
BACKGROUND
Stillbirth remains one of the most common adverse outcomes of pregnancy, yet is among the least studied. Occurrence of stillbirth is a tragic event faced by mother as well as obstetrician. It has implications on couple, their family and the health care providers. It reflects a failure or lapse in implementation of maternal and child health care programs. Worldwide 3.2 million stillbirth occur in world, 20-66 per 1000 total births in India in different states. Stillbirth in India is largely underreported. Stillbirths contribute to more than half of perinatal death. More than 2/3rd Stillbirth take place during pregnancy and remaining during course of labour. Registration of all live births and stillbirths, together with evaluation of cause of stillbirths are important initial steps for developing countries. A standard classification system would be important to document aetiology of stillbirth in developing countries.
THE METHODOLOGY WAS AS FOLLOWING
All cases who delivered a stillborn baby in the hospital were studied in details. The records were maintained date-wise. Initially, the basic demographic information was taken giving special attention to age, education, occupation, socioeconomic status, rural or urban residence etc. The two controls of live births were also asked the same details and the data were entered in Microsoft word excel sheet and analyzed by Chi-square test.
CONCLUSION
Incidence of stillbirth in MGIMS Sewagram which is Tertiary care centre placed in rural area was 30.57%. Incidence in relation to place (rural) 62.42%, more in antepartum 94.9% (149/157), in low socioeconomic status 48%. It was found more in 30-32 weeks of period of gestation as in this period most of medical disorders of pregnancy precipitate.

OBJECTIVES
Rheumatoid arthritis (RA) may adversely influence pregnancy and lead to adverse birth outcomes. This study estimated the risk of adverse fetal-neonatal and maternal pregnancy outcomes in women with RA.
DESIGN
This was a retrospective cohort study.
SETTING
We used both the National Health Insurance database and the Taiwan Birth Reporting System, between 2004 and 2014.
PARTICIPANTS
We identified 2 100 143 singleton pregnancies with 922 RA pregnancies, either live births or stillbirths, delivered by 1 468 318 women.
OUTCOME MEASURES
ORs with 95% CIs for fetal-neonatal and maternal outcomes were compared between pregnancies involving mothers with and without RA using an adjusted generalised estimating equation model.
RESULTS
Covariates including age, infant sex, Charlson Comorbidity Index, urbanisation, income, occupation, birth year and maternal nationality were adjusted. Compared with pregnancies in women without RA, pregnancies in women with RA showed that the fetuses/neonates had adjusted ORs (95% CI) of 2.03 (1.66 to 2.50) for low birth weight (n=123), 1.99 (1.64 to 2.40) for prematurity (n=141), 1.77 (1.46 to 2.15) for small for gestational age (n=144) and 1.35 (1.03 to 1.78) for fetal distress (n=60). Pregnancies in women with RA had adjusted ORs (95% CI) of 1.24 (1.00 to 1.52) for antepartum haemorrhage (n=106), 1.32 (1.15 to 1.51) for caesarean delivery (n=398), and 3.33 (1.07 to 10.34) for disseminated intravascular coagulation (n=3), compared with women without RA. Fetuses/neonates born to mothers with RA did not have a higher risk of being stillborn or having fetal abnormalities. Pregnant women with RA did not have increased risks of postpartum death, cardiovascular complications, surgical complications or systemic organ dysfunction.
CONCLUSIONS
Pregnancies in women with RA were associated with higher risks of multiple adverse fetal-neonatal and maternal outcomes; however, most pregnancies in these women were successful.

BACKGROUND
Birth of a fetus with no signs of life after a predefined age of viability is a nightmare for the obstetrician. Stillbirth is a sensitive indicator of maternal care during the antepartum and intrapartum period. Though there has been a renewed global focus on stillbirth as a public health concern, the decline in stillbirth rate (SBR) has not been satisfactory across the nations, with a large number of stillbirths occurring in the low- to middle-income countries (LMICs). Hence, the study was carried out to analyze maternal and fetal risk factors and their association with stillbirths in a tertiary care center in South India.
METHODS
This observational prospective study included pregnant women with stillbirth beyond 20 weeks of gestation or fetal weight more than 500 grams. Stillbirths were classified according to the simplified causes of death and associated conditions (CODAC) classification. Association between the risk factor and stillbirths was calculated with chi-square test and odds ratio with 95% confidence interval.
RESULTS
There were 171 stillbirths (2.97%) among total 5755 births. The SBR was 29.71/1000 births. Risk factors such as preterm delivery (OR: 22.33, 95% CI: 15.35-32.50), anemia (OR: 21.87, 95% CI: 15.69-30.48), congenital malformation (OR: 11.24, 95% CI: 6.99-18.06), abruption (OR: 10.14, 95% CI: 6.43-15.97), oligohydramnios (OR: 4.88, 95% CI: 3.23-7.39), and hypertensive disorder (OR: 3.01, 95% CI: 2.03-4.46) were significantly associated with stillbirths. The proportion of intrapartum stillbirths was found to be 5 (3%) among the study population.
CONCLUSION
Highest prevalent risk factors associated with stillbirth are anemia and prematurity. Intrapartum stillbirths can be reduced significantly through evidence-based clinical interventions and practices in resource-poor settings. There is a need to provide and assure access to specialized quality antenatal care to pregnant women to control the risk factors associated with stillbirths.
