Background: Surgery for adnexal mass does occur in pregnant women and therefore the choice of surgery during pregnancy needs to be carefully considered and studied. This study aimed to evaluate the safety and feasibility of Laparo-endoscopic Single-site Surgery (LESS) for adnexal mass during pregnancy and investigate the perioperative condition, pregnancy complications, and obstetric outcomes of operative women during pregnancy.

Methods: This study retrospectively collected medical records and surgery videos of 20 pregnant women who underwent LESS for adnexal mass between November 2019 and January 2022. Baseline characteristics, operative-related variables, and pregnancy outcomes were followed up.

Results: LESS for adnexal mass was successfully performed in 20 pregnant women, with very satisfactory surgery outcomes reported in all cases. The average gestational age at operation was 15⁺² weeks (range, 5⁺¹- 25⁺⁴ weeks). The median operative time was 80.8 min (range, 40 -185 min) and the average operative bleeding was 28.0 ml (range, 10-50 ml). The average VAS of 24 h postoperatively was 1 (range, 0-2), and the average length of hospital stay was 5.15 days (range, 3-7 days). All these women delivered a healthy newborn at full term except 1 woman induced abortion for her own reasons at 16⁺⁵ weeks gestational age (GA). The average GA of delivery was 39⁺¹ weeks (range, 37-40⁺¹ weeks), the average birth weight was 3228.95 g (range, 2740-3930 g), and the average Apgar score at 5 min was 9.95 (range, 9-10).

Conclusions: LESS for adnexal mass is safe and feasible for pregnant women.

Background: Escherichia coli (E. coli) is one of the main bacteria associated with preterm premature rupture of membranes by increasing pro-matrix metalloproteinase 9 (proMMP-9) and degradation of type IV collagen in human feto-maternal interface (HFMi). proMMP-9 is regulated by progesterone (P4) but it is unclear whether P4 inhibits proMMP in human maternal decidual (MDec). This study aimed to determine a role of P4 on proMMP-2 and - 9 and type IV collagen induced by E. coli infection in MDec.

Methods: Nine HFMi were mounted in a Transwell system. MDec was stimulated with P4 or E. coli for 3-, 6-, or 24-hours. proMMP-2, -9 and type IV collagen were assessed.

Results: Gelatin zymography revealed an increase in proMMP-9 after 3, 6, and 24 h of stimulating MDec with E. coli. Using immunofluorescence, it was confirmed the increase in the HFMi tissue and a reduction on the amount of type IV collagen leading to the separation of fetal amniochorion and MDEc. The degradative activity of proMMP-9 was reduced by 20% by coincubation with P4.

Conclusions: P4 modulates the activity of proMMP-9 induced by E. coli stimulation but it was unable to completely reverse the degradation of type IV collagen in human MDec tissue.

Background: Postpartum haemorrhage (PPH) continues to stand as the primary cause of maternal morbidity and mortality post-delivery, with twin pregnancies carrying a heightened risk of PPH compared to singleton deliveries.

Objectives: To investigate the incidence of primary PPH among twin pregnancies and report on maternal and peripartum characteristics within this population.

Methods: A literature search was conducted using data from PubMed, EMBASE, Cochrane, Scopus, and Web of Science. The search aimed to identify studies concerning mothers with twin pregnancies and postpartum haemorrhage (PPH) from the inception of each respective database to June 8th, 2023. Pooled means and proportions were analyzed using the generic inverse variance method. This review was registered prospectively with PROSPERO (CRD42023427192).

Results: A total of 21 studies involving 23,330 twin pregnant patients were included. Incidence of PPH for vaginal delivery and Caesarean delivery (CS) was found to be 10.9% (95% CI: -0.017, 0.235, I² = 96%) and 27.0% (95% CI: 0.180, 0.359, I² = 99%) respectively. In vitro fertilization (IVF) was the most common conception method at 62.0% (95% CI: 0.448, 0.792, I² = 100%) with 81.1% (95% CI: 0.708, 0.915, I² = 100%) of twins being dichorionic diamniotic.

Conclusion: This meta-analysis demonstrated more than one in ten vaginal deliveries and over one in four cesarean sections result in PPH for twin pregnancies. IVF is the predominant method of conception in this patient group and seems to contribute to subsequent PPH risk in specific mothers. While preliminary, these findings underscore the necessity for further well-designed and high-quality studies to validate these results.

Objectives: To study the possible associations between advanced maternal age and cesarean section(CS) under the two child policy.

Methods: This study used a cohort study from Dongguan People's Hospital in Guangdong Province, China from 2017 to 2020. The cohort was restricted to women aged ≥ 20 who give birth to babies with a gestational age of > 28 weeks and a weight of > 1000 g. Divide the advanced maternal age (AMA) pregnant women into two age groups: 35-39 years old and 40 years old or older age. We analyzed CS rate and CS contribution using the modified Robson classification system. Frequency of cesarean was determined for each group and compared by using χ² and prevalence ratio.

Results: Overall, 47654 women were included, of which 7924 (16.63%) were between the ages of 35 and 39, and 1529 (3.21%) were aged 40 or older. The total CS rate is 40.64%, with 36.10% for mothers aged 20 to 34, 57.90% for women aged 35 to 40, and 64.75% for women aged 40 or older age. In the AMA groups (n = 9453), Robson group 2' was the most common, followed by groups 5 and 10. Women at 40 years or older age were 3 times more likely to undergo a cesarean delivery in Robson group 1', and 1.76 times more likely in group 10. The CS rate in group 2' were statistically significantly higher in the very AMA group.

Conclusions: The CS rates increased noticeably with maternal age under the two child policy. Based on the modified Robson classification system, AMA women should pay more attention to primiparous women with single pregnancy, uterine scars, and premature birth in multiple pregnancies.

Introduction: The present study was conducted with the aim of evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after an expert panel review.

Method: The present study was a mixed methods observational study conducted at Umm al-Benin Hospital, the sole specialized obstetrics and gynecology center affiliated with Mashhad University of Medical Sciences. The study comprised three distinct stages: (1) Collecting primary ICD-PM codes assigned to perinatal death certificates, along with other relevant information, from October 2021 to March 2022; (2) Examining the circumstances of each perinatal death case and re-identifying the causes of death through a consensus process involving a panel of experts comprising pediatricians, obstetrics and gynecology specialists, and nursing and midwifery experts; presenting the new ICD-PM code; (3) Comparing the ICD-PM codes assigned to perinatal death certificates before and after the expert panel's evaluation.

Result: During the study period, a total of seven specialized panels were conducted to examine perinatal deaths. Out of the 71 cases, 41 were carefully reviewed by experts. These cases included 32 stillbirths and nine neonatal deaths. The examination process followed specific inclusion and exclusion criteria. The findings revealed that there were no significant changes in the causes of neonatal deaths. However, it was notable that 80% of the previously unknown causes of stillbirths were successfully identified. Notably, the occurrence of stillbirths increased by 78% due to maternal causes and conditions.

Conclusion: Convening panels of experts to discuss the causes of perinatal deaths can effectively reduce the percentage of unknown causes, as classified by ICD-PM. This approach also guarantees the availability of essential data for implementing effective interventions to decrease preventable perinatal deaths.

Background: Ankylosing Spondylitis (AS) is a systemic chronic rheumatic disease characterized by involvement of the axial skeletal and sacroiliac joints. Although this disease is not rare amongst women of reproductive age, data regarding pregnancy outcomes have demonstrated conflicting results. We therefore aimed to compare pregnancy and perinatal outcomes between women who suffered from AS to those who did not.

Methods: A retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). Included in the study were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. Women with an ICD-9 diagnosis of AS before or during pregnancy were compared to those without. Pregnancy, delivery, and neonatal outcomes were compared between the two groups using multivariate logistic regression models adjusting for potential confounders.

Results: A total of 9,096,788 women were inclusion in the analysis. Amongst them, 383 women (3.8/100,000) had a diagnosis of AS and the rest were controls. Women with AS, compared to those without, were more likely to be older; Caucasian; from higher income quartiles; suffer from thyroid disorders, and have multiple pregnancies (p < 0.001, all). After adjusting for confounders, patients in the AS group, compared to those without, had a higher rate of cesarean delivery (CD) (aOR 1.47, 95% CI 1.14-1.91, p = 0.003); gestational diabetes (aOR 1.55, 95% CI 1.02-2.33, p = 0.038); and placenta previa (aOR 3.6, 95% CI 1.6-8.12, p = 0.002). Regarding neonatal outcomes, patients with AS, compared to those without, had a higher rate of small-for-gestational-age (SGA) neonates (aOR 2.19, 95% CI 1.22-3.93, p = 0.009); and intrauterine fetal death (IUFD) (aOR 3.46, 95% CI 1.11-10.83, p = 0.033).

Conclusion: Women diagnosed with AS have an increased risk of obstetric complications, including CD, as well as an increased risk of SGA and IUFD.

Background: Globally, maternal mortality remains a critical issue, with male involvement during antenatal care (ANC) recognized as pivotal in reducing maternal deaths. Limited evidence on male involvement exists in low and middle-income countries, including Ethiopia. This study aimed to assess male involvement during antenatal care and associated factors among married men whose wives gave birth within the last 6 months in Debretabor town, North West Ethiopia in 2023.

Objective: Evaluate the level of male involvement during antenatal care and identify associated factors in the specified study area.

Methods: A community-based cross-sectional study involved 404 married men, whose wives had given birth within the past 6 months in Debretabor town. Data were collected using face-to-face interviews, entered into EpiData version 4.6, and analyzed using SPSS version 25. Logistic regression analyses determined associations.

Results: Male involvement during antenatal care in the study area was 46.8% (CI: 41.6, 51.5). Factors influencing involvement included men's attitude (AOR = 2.365), lack of male invitation to the examination room (AOR = 0.370), couples' living status (AOR = 4.461), men with secondary education (AOR = 4.052), men with diploma and above (AOR = 4.276), and complications during pregnancy (AOR = 6.976).

Conclusion and recommendation: The observed low level of male involvement underscores the need for targeted interventions. Stakeholders should promote male participation through counseling, community mobilization, and awareness campaigns.

Background: Postnatal care exhibits the lowest coverage levels in the obstetric continuum of care. The highest rates of maternal and newborn morbidity and mortality occur within 24 h of birth. Assessment of women in this time period could improve the detection of postpartum complications and maternal outcomes. This study determined the patterns of maternal assessment and the factors associated with postpartum complications.

Methods: This was a cross-sectional study involving observations of immediate postpartum care provided to women following uncomplicated vaginal births at three health facilities in Mpigi and Butambala districts (Uganda) from November 2020 to January 2021. Data were collected using an observation checklist and a data abstraction form for maternal and newborn social demographic data. The collected data were analyzed using Stata version 14.0. Maternal assessment patterns were summarized as frequencies, and the prevalence of postpartum complications was calculated. Logistic regression analysis was performed at both bivariate and multivariate levels to identify factors associated with developing postpartum complications among these women.

Results: We observed 263 women receiving care at three health facilities in the immediate postpartum period. The level of maternal assessments was very low at 9/263 (3.4%), 29/263(11%) and 10(3.8%) within the first two hours, at three hours and at the fourth hour, respectively. The prevalence of postpartum complications was 37/263 (14.1%), with 67.6% experiencing postpartum hemorrhage (PPH), 13.5% having perineal tears, and 10.8% having cervical tears. Mothers who did not undergo a postpartum check in the first three hours (p = 0.001), those who were discharged after 24 h (p = 0.038), and those who were transferred to the postpartum ward after two hours (p = 0.001) were more likely to have developed postpartum complications.

Conclusion: The maternal assessment patterns observed in the population were suboptimal. Women who were not assessed at the third hour and those transferred after two hours to the postnatal ward were more likely to have developed postpartum complications.

Background: Amniotic Band Syndrome (ABS) is a rare congenital condition characterized by the formation of fibrous bands within the amniotic sac that can entangle and restrict fetal development, leading to various deformities. In this report, we present an unprecedented case of fetal amniotic band ingestion in a monochorionic diamniotic (MCDA) twin pregnancy. Reporting this case is essential for expanding the understanding of the diverse presentations of amniotic bands, considering this rare entity in the differential diagnosis of prenatal ultrasound findings, and emphasizing the importance of vigilant prenatal monitoring and individualized management strategies.

Case presentation: A 35-year-old gravida 2, para 1 woman with an MCDA twin pregnancy experienced an uneventful pregnancy until the 33rd week, when routine ultrasonography revealed mild intrauterine growth restriction in both twins. At 35 weeks and 5 days gestation, the patient presented with mild abdominal pain. An emergency ultrasound revealed that Twin A ingested an amniotic band. Despite the absence of overt fetal distress, a comprehensive risk assessment was conducted, taking into account potential complications, such as airway obstruction and gastrointestinal issues due to prolonged amniotic band ingestion. Considering the risks versus the benefits of continued gestation and the near-term status, an emergency cesarean section was performed. The procedure resulted in the successful delivery of both twins with satisfactory Apgar scores. A 9-cm fibrous strand was promptly extracted from Twin A's oral cavity after delivery, confirming prenatal diagnosis. Both neonates underwent thorough examinations, revealing no additional anomalies, and demonstrated normal development during the nine-month follow-up.

Conclusion: This case highlights the inherent challenges in diagnosing and managing the rare presentations of amniotic band-related complications, particularly in MCDA twin pregnancies. The instance of fetal amniotic band ingestion underscores the vital role of comprehensive prenatal imaging in ensuring accurate diagnosis and tailoring individualized risk assessments throughout the pregnancy in such rare and complex situations.

Background: The recent Maternal Immune Activation (MIA) theory suggests maternal systemic inflammation may serve as a mediator in associations between prenatal maternal adversities and neurodevelopmental diseases in offspring. Given the co-exposure to multiple adversities may be experienced by pregnant person, it is unclear whether a quantitative index can be developed to characterize the inflammation related exposure level, and whether this index is associated with neurodevelopmental delays in offspring.

Methods: Based on Jiangsu Birth Cohort (JBC), a total of 3051 infants were included in the analysis. Inflammation related Prenatal Adversity Index (IPAI) was constructed using maternal data. Neurodevelopmental outcomes were assessed using the Bayley Scales of Infant and Toddler Development, third edition, screening test in one year. Multivariate linear regression and Poisson regression model were performed to analyze the associations between IPAI and neurodevelopment in offspring.

Results: Compared with "low IPAI" group, offspring with "high IPAI" have lower scores of cognition, receptive communication, expressive communication, and fine motor. The adjusted β were - 0.23 (95%CI: -0.42, -0.04), -0.47 (95%CI: -0.66, -0.28), -0.30 (95%CI: -0.49, -0.11), and - 0.20 (95%CI: -0.33, -0.06). Additionally, the elevated risk for noncompetent development of cognition and receptive communication among "high IPAI" group was observed. The relative risk [RR] and 95% confidence interval [CI] were 1.35 (1.01, 1.69) and 1.37 (1.09, 1.72).

Conclusions: Our results revealed a significant association between higher IPAI and lower scores across cognition, receptive communication, expressive communication, and fine motor domains, and an increased risk of noncompetent development in the cognition and receptive communication domains.
