Maternal and fetal characteristics and causes of stillbirth in a tertiary care hospital of Nepal: secondary analysis of registry-based surveillance data.

OBJECTIVES: Stillbirth is one of the vital indicators of quality care. This study aimed to determine maternal-fetal characteristics and causes of stillbirth in Nepal. DESIGN: Secondary analysis of single-centred registry-based surveillance data. SETTING: The study was conducted at the Department of Obstetrics and Gynecology, Chitwan Medical College Teaching Hospital, a tertiary care hospital located in Bharatpur, Nepal. PARTICIPANTS: All deliveries of intrauterine fetal death, at or beyond 22 weeks' period of gestation and/or birth weight of 500 g or more, conducted between 16 July 2017 and 15 July 2019 were included in the study. MAIN OUTCOME MEASURES: The primary outcome measure of this study was stillbirth, and the secondary outcome measures were maternal and fetal characteristics and cause of stillbirth. RESULTS: Out of 5282 institutional deliveries conducted over 2 years, 79 (1.5%) were stillbirths, which gives the stillbirth rate of 15 per 1000 births. Of them, the majority (75; 94.9%) were vaginal delivery and only four (5.1%) were caesarean section (p<0.0001). The proportion of the macerated type of stillbirth was more than that of the fresh type (58.2% vs 41.8%; p=0.13). Only half of the mothers who experienced stillbirth had received antenatal care. While the cause of fetal death was unknown in one-third of cases (31.6%; 25/79), among likely causes, the most common was maternal hypertension (29.1%), followed by intrauterine infection (8.9%) and fetal malpresentation (7.6%). Four out of 79 stillbirths (5%) had a birth defect. CONCLUSION: High rate of stillbirths in Nepal could be due to the lack of quality antenatal care. The country's health systems should be strengthened so that pregnancy-related risks such as maternal hypertension and infections are identified early on. Upgrading mothers' hygiene and health awareness is equally crucial in reducing fetal deaths in low-resource settings.

Cesarean Section Among all Deliveries in a Tertiary Care Centre of Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Worldwide there is a tremendous increase in cesarean section rate over the last decades which has been a global public health issue. This study aimed to find out the prevalence of cesarean delivery in a tertiary care center of Nepal. METHODS: A descriptive cross-sectional study was conducted among pregnant women at tertiary care centre from 15th September 2019 to 15th October 2020. Ethical clearance was taken from the Institutional Review Committee (Ref: CMC-IRC/077/078-200). Convenience sampling was done to reach the sample size. Basic demographic data, clinical indications and neonatal outcomes were noted. Data entry was done using Statistical Package for the Social Sciences version 20. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 3193 total deliveries, cesarean deliveries were 1412 (44.22%) at 95% Confidence Interval (42.49-45.94). Among caesarean deliveries 1086 (76.9%) were emergency cesarean sections. Most common indication for cesarean section was fetal distress (24.9%). Among 1437 newborns, 1428 (99.4%) were live births, 1387 (98.2%) were singleton and 801 (55.7%) were male. Nearly one third 418 (29.1%) neonates required neonatal intensive care unit admission and transient tachypnoea of newborns (44.28% in emergency and 60.46% in elective cesarean delivery) was the most common indication for admission. CONCLUSIONS: The prevalence of cesarean delivery was found to be higher than that recommended by the World Health Organisation. Fetal distress was the leading indication for cesarean deliveries.

Association between Lactobacillus species and bacterial vaginosis-related bacteria, and bacterial vaginosis scores in pregnant Japanese women.

BACKGROUND: Bacterial vaginosis (BV), the etiology of which is still uncertain, increases the risk of preterm birth. Recent PCR-based studies suggested that BV is associated with complex vaginal bacterial communities, including many newly recognized bacterial species in non-pregnant women. METHODS: To examine whether these bacteria are also involved in BV in pregnant Japanese women, vaginal fluid samples were taken from 132 women, classified as normal (n = 98), intermediate (n = 21), or BV (n = 13) using the Nugent gram stain criteria, and studied. DNA extracted from these samples was analyzed for bacterial sequences of any Lactobacillus, four Lactobacillus species, and four BV-related bacteria by PCR with primers for 16S ribosomal DNA including a universal Lactobacillus primer, Lactobacillus species-specific primers for L. crispatus, L. jensenii, L. gasseri, and L. iners, and BV-related bacterium-specific primers for BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium. RESULTS: The prevalences of L. crispatus, L. jensenii, and L. gasseri were significantly higher, while those of BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium were significantly lower in the normal group than in the BV group. Unlike other Lactobacillus species, the prevalence of L. iners did not differ between the three groups and women with L. iners were significantly more likely to have BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium. Linear regression analysis revealed associations of BVAB2 and Megasphaera with Nugent score, and multivariate regression analyses suggested a close relationship between Eggerthella-like bacterium and BV. CONCLUSION: The BV-related bacteria, including BVAB2, Megasphaera, Leptotrichia, and Eggerthella-like bacterium, are common in the vagina of pregnant Japanese women with BV. The presence of L. iners may be correlated with vaginal colonization by these BV-related bacteria.
