RESUMO
Objective: To study and compare the clinical effects of cervical pessary and progesterone for preventing preterm birth in singleton pregnant women with a short cervical length (CL). Methods: This study was a prospective cohort study. A total of 148 pregnant women with CL≤25 mm, as determined by ultrasound examination performed before 28 weeks of pregnancy, were included in the study. All subjects were admitted to West China Second Hospital, Sichuan University between August 2020 and December 2022. According to their treatment plans, the pregnant women were divided into a cervical pessary group (n=55) and a progesterone group (n=93). Spontaneous preterm birth before 37 weeks of pregnancy was defined as the main outcome index. Preterm birth (abortion) or spontaneous preterm birth (abortion) before 37, 34, 32, 30, and 28 weeks of pregnancy, mean extended gestational age, neonatal morbidity, and neonatal mortality were the secondary outcome indicators. The pregnancy outcomes and the neonatal outcomes of the two groups were compared and statistically analyzed. Results: There was no statistically significant difference in the incidence of preterm birth (including iatrogenic preterm birth, spontaneous preterm birth, and abortion) before 37, 34, 32, 30, and 28 weeks between the cervical pessary group and the progesterone group. When iatrogenic preterm birth was excluded, the incidence of spontaneous preterm birth before 37 weeks was lower in the cervical pessary group (23.6%) than that in the progesterone group (41.9%), with the difference between the two groups being statistically significant (P=0.024). There was no statistically significant difference in the incidence of spontaneous preterm birth (including miscarriage) before 34, 32, 30, and 28 weeks. There was no statistically significant difference in the incidence of neonatal morbidity, the rate of transfer to the neonatal care unit after birth, and the neonatal mortality rate between the two groups. Multivariate logistic analysis showed that treatment with cervical pessary was a protective factor for spontaneous preterm birth before 37 weeks compared to progesterone therapy. Conclusion: Using cervical pessary to prevent spontaneous preterm birth in singleton pregnant women with a short cervical length in the second trimester can significantly reduce the incidence of spontaneous preterm birth before 37 weeks.

Objective: Few comparisons have been implemented between different prenatal care utilization indices and their effects on adverse outcomes. This study investigated the appropriateness of Chinese antenatal care (ANC) regulations and compared Chinese and American adequacy of prenatal care utilization (APNCU) scores. Methods: From 2010 to 2022, the medical records of 60,114 pregnant women were collected from the electronic medical record system (EMRS) in Zhoushan, China. ANC utilization was measured using the APNCU score and five times antenatal care (ANC5). Birth weight outcomes, including small for gestational age (SGA) and large for gestational age (LGA), low birth weight (LBW), macrosomia, birth weight, and preterm birth (PTB), were utilized as outcomes. Multinomial, linear, and logistic regression were used to analyze the association of ANC5 and APNCU with outcomes, respectively. Crossover analysis was implemented to compare the interaction between ANC5 and APNCU on the outcomes. Results: Women who received inadequate prenatal care had increased odds for PTB (ANC5: odds ratio (OR) = 1.12, 95% confidence interval (95%CI) = 1.03-1.21; APNCU: OR = 1.18, 95%CI: 1.07-1.29), delivering SGA infants (ANC5: OR = 1.13, 95%CI = 1.07-1.21; APNCU: OR = 1.11, 95%CI = 1.03-1.20). Crossover analysis revealed that inadequate prenatal care in APNCU only was significantly associated with an increased risk of PTB (OR = 1.48, 95%CI: 1.26-1.73). Conclusion: Women with inadequate prenatal care in ANC5 or APNCU were more likely to suffer from adverse birth outcomes, including PTB, birth weight loss, SGA, and LBW. It indicated that adequate prenatal care is necessary for pregnant women. However, there were interactions between ANC5 and APNCU on PTB, with inadequate prenatal care use by APNCU showing the highest risk of PTB. This indicates that APNCU would be a better tool for evaluating prenatal care use.

Importance: Pregnancy may contribute to the development or exacerbation of obstructive sleep apnea (OSA) and increase the risk of gestational complications. Continuous positive airway pressure (CPAP) is the first-line and criterion standard treatment for OSA and is regarded as the most feasible choice during pregnancy. However, the association between CPAP therapy in pregnant women with OSA and reduced gestational complications remains inconclusive. Objective: To investigate the association between CPAP therapy in pregnant women with OSA and the reduction of adverse hypertensive outcomes during gestation. Data Sources: Keyword searches of PubMed, Embase, and the Cochrane Database of Systematic Reviews and Clinical Trials were conducted from inception to November 5, 2023. Study Selection: Original studies reporting the treatment effect of CPAP use on lowering hypertension and preeclampsia risks in pregnant women with OSA were selected. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed in the reporting of reviews. Data were independently extracted by 2 authors. Random-effects model meta-analyses were performed and risk ratios (RRs) reported. Subgroup analysis, meta-regression based on age and body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), and publication bias assessment were also conducted. Main Outcome and Measures: The primary outcome was the RR of gestational hypertension and preeclampsia between pregnant women with OSA receiving CPAP treatment and those who did not receive CPAP treatment. Results: Six original studies in 809 participants (mean age, 31.4 years; mean BMI, 34.0) were identified and systematically reviewed for meta-analysis. The pooled results showed significant differences between the intervention (CPAP use) and the control (non-CPAP use) groups in reducing the risk of gestational hypertension (RR, 0.65; 95% CI, 0.47-0.89; P = .008) and preeclampsia (RR, 0.70; 95% CI, 0.50-0.98; P = .04). Meta-regression revealed that patients' age (coefficient, -0.0190; P = .83) and BMI (coefficient, -0.0042; P = .87) were not correlated with reduction of risk of hypertension and preeclampsia. Conclusions and Relevance: These findings suggest that implementing CPAP treatment in pregnant women with OSA may reduce the risk of gestational hypertension and preeclampsia.

BACKGROUND: There are no established guidelines for the follow up of infants born after a prenatal diagnosis of a genomic copy number variant (CNV), despite their increased risk of developmental issues. The aims of this study were (i) to determine the perinatal outcomes of fetuses diagnosed with and without a CNV, and (ii) to establish a population-based paediatric cohort for long term developmental follow up. METHODS: An Australian state-wide research database was screened for pregnant individuals who had a prenatal chromosomal microarray (CMA) between 2013-2019 inclusive. Following linkage to laboratory records and clinical referrer details, hospital records were manually reviewed for study eligibility. Eligible participants were mother-child pairs where the pregnancy resulted in a livebirth, the mother was able to provide informed consent in English (did not require a translator) and the mother was the primary caregiver for the child at hospital discharge after birth. Research invitations were sent by registered post at an average of six years after the prenatal diagnostic test. Statistical analysis was performed in Stata17. RESULTS: Of 1832 prenatal records examined, 1364 (74.5%) mother-child pairs were eligible for recruitment into the follow up cohort. Of the 468 ineligible, 282 (60.3%) had 'no live pregnancy outcome' (209 terminations of pregnancy (TOP) and 73 miscarriages, stillbirths, and infant deaths), 157 (33.5%) required a translator, and 29 (6.2%) were excluded for other reasons. TOP rates varied by the type of fetal CNV detected: 49.3% (109/221) for pathogenic CNVs, 18.2% (58/319) for variants of uncertain significance and 3.3% (42/1292) where no clinically significant CNV was reported on CMA. Almost 77% of invitation letters were successfully delivered (1047/1364), and the subsequent participation rate in the follow up cohort was 19.2% (201/1047). CONCLUSIONS: This study provides Australia's first population-based data on perinatal outcomes following prenatal diagnostic testing with CMA. The relatively high rates of pregnancy loss for those with a prenatal diagnosis of a CNV presented a challenge for establishing a paediatric cohort to examine long term outcomes. Recruiting a mother-child cohort via prenatal ascertainment is a complex and resource-intensive process, but an important step in understanding the impact of a CNV diagnosis in pregnancy and beyond.

RESEARCH QUESTION: Does luteinizing hormone (LH) levels on human chorionic gonadotropin (HCG) trigger day (LHHCG) affect the clinical outcomes of patients with diminished ovarian reserve (DOR) undergoing gonadotropin-releasing hormone antagonist (GnRH-ant) protocol? METHODS: Retrospective analysis fresh embryo transfer cycles of DOR patients who underwent GnRH-ant protocol from August 2019 to June 2023. The participants were divided into different groups according to LHHCG level and age. The clinical data and outcomes were compared between groups. RESULTS: In patients with DOR, the HCG positive rate (59.3% versus 39.8%, P = 0.005), embryo implantation rate (34.5% versus 19.7%, P = 0.002), clinical pregnancy rate (49.2% versus 28.4%, P = 0.003), live birth rate (41.5% versus 22.7%, P = 0.005) in LHHCG < 2.58 IU/L group were significantly higher than LHHCG ≥ 2.58 IU/L group. There was no significant correlation between LHHCG level and clinical pregnancy in POSEIDON group 3. In POSEIDON group 4, the HCG positive rate (52.8% versus 27.0%, P = 0.015), embryo implantation rate (29.2% versus 13.3%, P = 0.023), clinical pregnancy rate (45.3% versus 18.9%, P = 0.010) in LHHCG < 3.14 IU/L group were significantly higher than LHHCG ≥ 3.14 IU/L group. Logistic regression analysis indicated that LHHCG level was an independent influencing factor for clinical pregnancy in POSEIDON group 4 patients (OR = 3.831, 95% CI: 1.379-10.643, P < 0.05). CONCLUSIONS: LHHCG level is an independent factor affecting pregnancy outcome of fresh embryo transfer in DOR patients undergoing GnRH-ant protocol, especially for advanced-aged women. LHHCG had a high predictive value for POSEIDON group 4 patients, and LHHCG ≥ 3.14 IU/L predicts poor pregnancy outcomes.

Planning for pregnancy and possibility of disease modifying treatment (DMTs) is an important question in female patients of reproductive age who suffer from multiple sclerosis (MS). The frequency of refusals to plan pregnancy is 14%. This is due to numerous concerns about the course of pregnancy, its outcomes, as well as the possible effect of DMTs on the fetus and the probability of disease transmission to a child. The article discusses immunological reactions taking place in MS patients during pregnancy, which are protective in its nature. Data for all groups of DMTs regarding pregnancy planning, possible risks of their impact on fertility and teratogenicity is presented.

Objective: To evaluate the mode of delivery according to Robson classification (RC) and the perinatal outcomes in fetal growth restriction (FGR) and small for gestational age (SGA) fetuses. Methods: Retrospective cohort study by analyzing medical records of singleton pregnancies from two consecutive years (2018 and 2019). FGR was defined according to Delphi Consensus. The Robson groups were divided into two intervals (1-5.1 and 5.2-10). Results: Total of 852 cases were included: FGR (n = 85), SGA (n = 20) and control (n=747). FGR showed higher percentages of newborns < 1,500 grams (p<0.001) and higher overall cesarean section (CS) rates (p<0.001). FGR had the highest rates of neonatal resuscitation and neonatal intensive care unit admission (p<0.001). SGA and control presented higher percentage of patients classified in 1 - 5.1 RC groups, while FGR had higher percentage in 5.2 - 10 RC groups (p<0.001). FGR, SGA and control did not differ in the mode of delivery in the 1-5.1 RC groups as all groups showed a higher percentage of vaginal deliveries (p=0.476). Conclusion: Fetuses with FGR had higher CS rates and worse perinatal outcomes than SGA and control fetuses. Most FGR fetuses were delivered by cesarean section and were allocated in 5.2 to 10 RC groups, while most SGA and control fetuses were allocated in 1 to 5.1 RC groups. Vaginal delivery occurred in nearly 60% of FGR allocated in 1-5.1 RC groups without a significant increase in perinatal morbidity. Therefore, the vaginal route should be considered in FGR fetuses.

OBJECTIVES: To investigate all pregnancies and analyze the factors influencing pregnancy outcomes in patients with adenomyosis after high intensity focused ultrasound (HIFU). MATERIALS AND METHODS: A total of 231 patients with adenomyosis who completed HIFU and wished to conceive were enrolled. The symptom improvement and information of pregnancy were recorded during the follow-up period. Factors influencing pregnancy outcomes were analyzed using multivariate regression analysis and survival analysis. RESULTS: After HIFU, 100 of 231 (43.3%) patients became pregnant within 96 months, including 77 (77/194, 39.7%) in natural and 23 (23/37, 62.2%) in vitro fertilization and embryo transfer (IVF-ET) pregnancies following gonadotropin-releasing hormone agonist (GnRHa). Among the 108 (46.8%, 108/231) infertile patients (defined as the failure to achieve pregnancy after 12 months of regular unprotected sexual intercourse, 40 primary infertility and 68 secondary infertility), 31 (28.7%) became pregnant. At the end of the follow-up, 70 successfully delivered 71 healthy babies. No uterine rupture occurred during pregnancy and delivery. Patients with pelvic adhesion and infertility history had a lower pregnancy chance than that of patients without pelvic adhesion and infertility history (OR < 1, p < 0.05). Patients with small adenomyotic lesion volume had a greater pregnancy chance than that of patients with large lesion volume (OR < 1, p < 0.05). IVF-ET following GnRHa had a better pregnancy chance (p < 0.05). CONCLUSIONS: HIFU seems to have a beneficial effect on fertility of patients with adenomyosis. Pelvic adhesion, infertility history, and large adenomyotic lesion volume have adverse effects on pregnancy, but IVF-ET following GnRHa after HIFU could increase the pregnancy chance.

OBJECTIVES: To characterise the exposure to valproate within a cohort of pregnant women using electronic health records (EHRs) from Catalonia (System for the Development of Research in Primary Care, SIDIAP). DESIGN: Drug-utilisation cohort study covering the period from January 2011 to June 2020. The study included pregnancy episodes of women from Catalonia identified by the algorithm. SETTING: Data were sourced from SIDIAP, a comprehensive EHR repository that includes information from various data sources: recorded prescriptions (both hospital and primary care), diagnoses and sociodemographic characteristics identified by primary care physicians, and sexual and reproductive health data from ASSIR (used by gynaecologists and midwives). PARTICIPANTS: Women aged 12-50 with at least one pregnancy episode occurred during January 2011-June 2020 and at least a prescription of valproate during pregnancy. PRIMARY AND SECONDARY OUTCOMES: Primary outcomes included valproate exposure, measured through prevalence and cumulative incidence in pregnancy episodes and by trimester. The impact of regulatory measures (risk mitigation measures, RMMs) was assessed, and prescriptions over time were analysed using interrupted time series analysis. Secondary outcomes included health issues, pregnancy outcomes, smoking habits and socioeconomic characteristics. RESULTS: A total of 99 605 pregnancies were identified, with at least 3.03 (95% CI 2.69 to 3.39) exposed to valproate at some point (302 pregnancies, 276 women). The median pregnancy duration was 38.30 weeks (IQR 12.6-40.1), and the median age at pregnancy was 32.37 years (IQR 27.20-36.56). Epilepsy was the most frequent health issue. The prevalence and cumulative incidence of valproate prescriptions decreased during pregnancy and increased postpregnancy. The RMMs implemented in 2014 led to a reduction in monthly valproate prescriptions during pregnancy in this cohort. CONCLUSIONS: The study highlights the decline in valproate prescriptions during pregnancy due to RMMs and underscores the need for standardised methodologies in future studies to ensure the safety of pregnant patients and optimise scientific evidence.

BACKGROUND: Hepatitis B virus (HBV) is one of the most widespread viruses worldwide and a major cause of hepatitis, cirrhosis, and hepatocellular carcinoma. Previous studies have revealed the impacts of HBV infection on fertility. An increasing number of infertile couples with chronic hepatitis B (CHB) virus infection choose assisted reproductive technology (ART) to meet their fertility needs. Despite the high prevalence of HBV, the effects of HBV infection on assisted reproduction treatment remain limited and contradictory. OBJECTIVE: The aim of this study was to provide a comprehensive overview of the effect of HBV infection on fertility and discuss its effects on pregnancy outcomes, vertical transmission, pregnancy complications, and viral activity during ART treatment. METHODS: We conducted a literature search in PubMed for studies on HBV infection and ART published from 1996 to 2022. RESULTS: HBV infection negatively affected fertility in both males and females. Existing research shows that HBV infection may increase the risk of pregnancy complications in couples undergoing assisted reproduction treatment. The impact of HBV infection on the pregnancy outcomes of ART is still controversial. Current evidence does not support that ART increases the risk of vertical transmission of HBV, while relevant studies are limited. With the development of ART, the risk of HBV reactivation (HBVr) is increasing, especially due to the wide application of immunosuppressive therapy. CONCLUSIONS: Regular HBV infection screening and HBVr risk stratification and management are essential to prevent HBVr during ART. The determination of optimal strategy and timing of prophylactic anti-HBV therapy during ART still needs further investigation.

BACKGROUND: Gestational DNA methylation age (GAmAge) has been developed and validated in European ancestry samples. Its applicability to other ethnicities and associations with fetal stress and newborn phenotypes such as inflammation markers are still to be determined. This study aims to examine the applicability of GAmAge developed from cord blood samples of European decedents to a racially diverse birth cohort, and associations with newborn phenotypes. METHODS: GAmAge based on 176 CpGs (Haftorn GAmAge) was calculated for 940 children from a US predominantly urban, low-income, multiethnic birth cohort. Cord blood DNA methylation was profiled by Illumina EPIC array. Newborn phenotypes included anthropometric measurements and, for a subset of newborns (N = 194), twenty-seven cord blood inflammatory markers (sandwich immunoassays). RESULTS: GAmAge had a stronger correlation with GEAA in boys (r = 0.89, 95% confidence interval (CI) [0.87,0.91]) compared with girls (r = 0.83, 95% CI [0.80,0.86]), and was stronger among extremely preterm to very preterm babies (r = 0.91, 95% CI [0.81,0.96]), compared with moderate (r = 0.48, 95% CI [0.34,0.60]) and term babies (r = 0.58, 95% CI [0.53,0.63]). Among White newborns (N = 51), the correlation between GAmAge vs. GEAA was slightly stronger (r = 0.89, 95% CI [0.82,0.94]) compared with Black/African American newborns (N = 668; r = 0.87, 95% CI [0.85,0.89]) or Hispanic (N = 221; r = 0.79, 95% CI [0.74,0.84]). Adjusting for GEAA and sex, GAmAge was associated with anthropometric measurements, cord blood brain-derived neurotrophic factor (BDNF), and monocyte chemoattractant protein-1 (MCP-1) (p < 0.05 for all). CONCLUSIONS: GAmAge estimation is robust across different populations and racial/ethnic subgroups. GAmAge may be utilized as a proxy for GEAA and for assessing fetus development, indicated by inflammatory state and birth outcomes.

OBJECTIVE: The aim of this study was to evaluate mitofusin-2 levels and fetal Doppler ultrasonography effects in patients with severe preeclampsia. METHODS: This single-center case-control study was conducted in the gynecology service of the university hospital in Van. A total of 90 pregnant women aged 18-40 years were included in the study. Of these, 30 are normal, 30 have mild preeclampsia, and 30 are pregnant with severe preeclampsia. In this study, especially in severe preeclampsia patients, serum mitofusin-2 levels and important fetal Doppler flows such as uterine arterial pressure, umbilical arterial pressure, and 1st and 5th minute Apgar scores, birth weight, and the relationship between postnatal outcomes such as week of birth and the number of patients in the neonatal intensive care unit were investigated. RESULTS: There was a significant difference between the three groups in terms of mitofusin-2 levels, which was the highest in the group (p<0.05). Maternal serum mitofusin-2 levels were positively correlated with uterine arterial pressure (r=0.543, p=0.007), umbilical arterial pressure (r=0.238, p=0.008), diastolic blood pressure, and systolic blood pressure (p<0.001). Receiver operating characteristic curve of mitofusin-2 in predicting preeclampsia is as follows: optimal cutoff 1.6 ng/mL; area under the curve: 0.861; 95%CI: 0.786-0.917; sensitivity: 83.9%; and specificity: 70.0%, (p≤0.001). A one-unit increase in mitofusin-2 resulted in a statistically significant 4.21-fold increase in preeclampsia risk. CONCLUSION: This study recommends the use of mitofusin-2 together with fetal Doppler ultrasound findings as a reliable indicator of preeclampsia severity.

OBJECTIVE: The aim of this study was to compare the obstetric and perinatal complications in women who became pregnant with autologous oocytes and those who received donated oocytes (DO) in intracytoplasmic sperm injection cycles (ICSI). METHODS: A retrospective cohort study was carried out by collecting data from medical records between 2019 and 2022. Only patients who underwent ICSI in an induced cycle using their own or freshly DO, with male infertility factor and tubal factor, were included. RESULTS: A total of 120 patients were assessed, comprising 51 cases utilizing their own oocytes (control group) and 69 cases employing DO (study group). Patients receiving DO (n=69) exhibited a significantly higher mean age compared to those utilizing their own oocytes (n=51) (41.96±2.16 vs 38.54±1.42 years, p<0.001). There was no significant association between the source of oocytes and gestational age at delivery (p=0.296), birth weight (p=0.836), admission to neonatal intensive care unit (ICU) (p=0.120), or maternal admission to adult ICU (p=0.767). Additionally, the origin of oocytes did not demonstrate any significant association with the risk of pre-eclampsia (p=0.357), gestational diabetes mellitus (p=0.187), premature rupture of membranes (p=0.996), uterine atony (p=0.996), placenta previa (p=0.393), oligohydramnios (p=0.393), or gestational hypertension (p=0.393)." CONCLUSION: An increase in obstetric and perinatal complications was not observed in pregnancies with DO compared to pregnancies with autologous oocytes in women undergoing ICSI without prior comorbidities. Further studies with larger sample sizes are required to validate our findings.

INTRODUCTION: Despite the progress in reducing child mortality, the rate remains high, particularly in sub-Saharan African countries. Limited data exist on child survival and other birth outcomes by sex. This study compared survival rates and birth outcomes by sex among neonates and children under 2 in Ethiopia. METHODS: Women who gave birth after 28 weeks of gestation and their newborns were included in the analysis. Survival probabilities were estimated for males and females in the neonatal period as well as the 2-year period following birth using Kaplan-Meier curves. HRs and 95% CIs were compared between males and females under 2. Descriptive statistics and χ2 tests were used to determine the sex-disaggregated variation in the birth outcomes of preterm birth, low birth weight (LBW), stillbirth, small for gestational age (SGA) and large for gestational age (LGA). RESULTS: The study included a total of 3904 women and child pairs. The neonatal mortality rate for males (3.4%, 95% CI 2.6% to 4.2%) was higher compared with females (1.7%, 95% CI 1.1% to 2.3%). The hazard of death during the first 28 days of life was approximately two times higher for males compared with females (HR 1.99, 95% CI 1.30 to 3.06) but was not significantly different after this period. While there was a non-significant difference between males and females in the proportion of preterm, LBW and LGA births, we found a significantly higher proportion of stillbirth (2.7% vs 1.3%, p=0.003) and SGA (20.5% vs 15.6%, p<0.001) for males compared with females. CONCLUSIONS: This study identified a significant sex difference in mortality and birth outcomes. We recommend focusing future research on the mechanisms of these sex differences in order to better design intervention programmes to reduce disparities and improve outcomes for neonates.

Alpha-fetoprotein (AFP) is a structural serum glycoprotein that plays vital roles in reproduction and mammalian development. Analysis of serum prolactin (PRL) is considered one of the useful methods for diagnosing pregnancy in Asian elephants. However, the expression profiles of AFP in pregnant and nonpregnant Asian elephants remain unclear, nor is the relationship with PRL. In this study, serum seven gonadal hormones and AFP in three pregnant and seven nonpregnant Asian elephants were analysed by via radioimmunoassay (RIA) and enzyme-linked immunosorbent (ELISA) assay. We found that the mean (±SD) concentration of prolactin (PRL) in pregnant (136.782 ± 30.987 ng/mL) elephants was significantly higher than that in nonpregnant elephants (52.803 ± 21.070 ng/mL; p ≤ 0.0005). The mean (±SD) concentration of AFP in pregnant elephants (11.598 ± 0.824 ng/mL) was significantly higher than that in nonpregnant elephants (7.200 ± 2.283 ng/mL; p ≤ 0.05). Furthermore, the AFP concentration was positively correlated with the PRL concentration in the 10 Asian elephants studied. In conclusion, our findings suggest that serum AFP concentration is a potential biomarker of pregnancy outcomes in Asian elephants.

This study aimed to explore the relationship between female age and pregnancy outcomes in patients undergoing their first elective single embryo transfer (eSET) of in vitro fertilization (IVF) cycles. The retrospective cohort study encompassed 7089 IVF/intracytoplasmic sperm injection (ICSI) patients of the Reproductive Medicine Center, Henan Provincial Peoples' Hospital of China, from September 1, 2016, to May 31, 2022. Patients all received the first eSET in their IVF/ICSI cycles. A generalized additive model (GAM) was employed to examine the the dose-response correlation between age and pregnancy outcomes, namely the clinical pregnancy rate (CPR) and ongoing pregnancy rate (OPR). Logistic regression model was employed to ascertain the correlation between the CPR/OPR and age. The study cohort has an average age of 30.74; 3843 patients got clinical pregnancy rate of 61.40% and ongoing pregnancy rate of 54.21%. The multiple pregnancy rate of is 1.24%. For patients aged 34 and above, the CPR decreased by 10% for every 1-year increase in age (adjusted OR 0.90, 95% CI 0.84-0.96, p < 0.0001). Similarly, the OPR decreased by 16% for every 1-year increase in age (adjusted OR 0.84, 95% CI 0.81-0.88, p < 0.0001). Patients aged 35-37 years had an acceptable OPR of 52.4% after eSET, with a low multiple pregnancy rate (1.1%). Pregnancy outcomes were significantly better in blastocyst cycles compared to cleavage embryo cycles, and this trend was more pronounced in older patients. There was a non-linear relationship between female age and pregnancy outcomes in patients undergoing their first eSET cycles. The clinical pregnancy rate and ongoing pregnancy rate decreased significantly with age, especially in women older than 34 years. For patients under 37 years old, single embryo transfer should be prioritized. For patients over 38 years old with available blastocysts, eSET is also recommended.

OBJECTIVES: To determine how pre-existing conditions contribute to racial disparities in adverse maternal outcomes and incorporate these conditions into models to improve risk prediction for racial minority subgroups. STUDY DESIGN: We used data from the "Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-be (nuMoM2b)" observational cohort study. We defined multimorbidity as the co-occurrence of two or more pre-pregnancy conditions. The primary outcomes of interest were severe preeclampsia, postpartum readmission, and blood transfusion during pregnancy or up to 14 days postpartum. We used weighted Poisson regression with robust variance to estimate adjusted risk ratios and 95% confidence intervals, and we used mediation analysis to evaluate the contribution of the combined effects of pre-pregnancy conditions to racial/ethnic disparities. We also evaluated the predictive performance of our regression models by racial subgroup using the area under the receiver operating characteristic curve (AUC) metric. RESULTS: In the nuMoM2b cohort (n = 8729), accounting for pre-existing conditions attenuated the association between non-Hispanic Black race/ethnicity and risk of severe preeclampsia. Cardiovascular and kidney conditions were associated with risk for severe preeclampsia among all women (aRR, 1.77; CI, 1.61-1.96, and aRR, 1.27; CI, 1.03-1.56 respectively). The mediation analysis results were not statistically significant; however, cardiovascular conditions explained 36.6% of the association between non-Hispanic Black race/ethnicity and severe preeclampsia (p = 0.07). The addition of pre-pregnancy conditions increased model performance for the prediction of severe preeclampsia. CONCLUSIONS: Pre-existing conditions may explain some of the association between non-Hispanic Black race/ethnicity and severe preeclampsia. Specific pre-pregnancy conditions were associated with adverse maternal outcomes and the incorporation of comorbidities improved the performance of most risk prediction models.

BACKGROUND: Appropriate physical activity (PA) and good sleep are beneficial to maternal and fetal health. This paper sought to explore the associations of PA and sleep quality among healthy women at the first and second trimesters of pregnancy on mental health and pregnancy outcomes. METHODS: Totally 268 healthy pregnant women were retrospectively analyzed as study subjects, 134 each in the first trimester (FT) and second trimester (ST). Their baseline clinical data were obtained respectively at two stages of pregnancy. The PA/sleep quality of subjects were assessed through the Pregnancy Physical Activity Questionnaire-Chinese version (PPAQ-C)/Pittsburgh Sleep Quality Index (PSQI) scale. The mental health was assessed via the Hospital Anxiety and Depression Scale (HADS). The correlations of PA and sleep quality with mental health were analyzed using Spearman correlation analysis. Pregnancy outcomes of all subjects, associations of moderate intensity (MI) PA and sleep quality with adverse pregnancy outcomes, and independent influencing factors for adverse outcomes were analyzed. RESULTS: Pregnant women in the ST group exhibited higher levels of MI, worse sleep quality, and lower levels of anxiety and depression than those in the FT group. Anxiety and depression were negatively correlated with MI but positively linked with PSQI scores at the first and second trimesters. MI ≥ 7.5 MET-h/week and good sleep quality were associated with a reduced incidence of adverse pregnancy outcomes. CONCLUSION: MI ≥ 7.5 MET-h/week and good sleep quality at the first and second trimesters of pregnancy benefit mental health and markedly reduce the occurrence of adverse pregnancy outcomes.

BACKGROUND: Recently, a history of endometriosis has been reported to be associated with several perinatal complications. However, it is unknown whether pre-pregnancy treatment for endometriosis reduces perinatal complications. In this study, we aimed to clarify the association between endometriosis and perinatal complications and investigate whether there is a significant difference in the incidence of placenta previa depending on the degree of surgical completion of endometriosis before pregnancy. METHODS: This case-control study included 2781 deliveries at the Hirosaki University Hospital between January 2008 and December 2019. The deliveries were divided into a case group with a history of endometriosis (n = 133) and a control group without endometriosis (n = 2648). Perinatal outcomes and complications were compared between the case and control groups using a t-test and Fisher's exact test. Multiple logistic regression models were used to identify the risk factors for placenta previa. Additionally, we examined whether the degree of surgical completion of endometriosis before pregnancy was associated with the risk of placenta previa. RESULTS: Patients with a history of endometriosis had a significantly higher risk of placenta previa (crude odds ratio, 2.66; 95% confidence interval, 1.37â4.83). Multiple logistic regression analysis showed that a history of endometriosis was a significant risk factor for placenta previa (adjusted odds ratio, 2.30; 95% confidence interval, 1.22â4.32). In addition, among patients with revised American Society for Reproductive Medicine stage III-IV endometriosis, the incidence of placenta previa was significantly lower in patients who underwent complete surgery (3/51 patients, 5.9%) than in those who did not (3/9 patients, 33.3%) (p = 0.038). CONCLUSIONS: A history of endometriosis is an independent risk factor for placenta previa. Given the limitations of this study, further research is needed to determine the impact of endometriosis surgery on perinatal complications.

Importance: Small, geographically limited studies report that people with intellectual and developmental disabilities (IDD) have increased risk for serious pregnancy-related and birth-related challenges, including preeclampsia, preterm birth, and increased anxiety and depression, than their peers. United States-based population-level data among people with IDD are lacking. Objectives: To identify perinatal and postpartum outcomes among a national, longitudinal sample of people with IDD enrolled in public health insurance, compare subgroups of people with IDD, and compare outcomes among people with IDD with those of peers without IDD. Design, Setting, and Participants: This retrospective cohort study used national Medicaid claims from January 1, 2008, to December 31, 2019, for 55â¯440 birthing people with IDD and a random sample of 438â¯557 birthing people without IDD. Medicaid funds almost half of all births and is the largest behavioral health insurer in the US, covering a robust array of services for people with IDD. Statistical analysis was performed from July 2023 to June 2024. Exposure: People who had a documented birth in Medicaid during the study years. Main Outcome and Measures: Perinatal outcomes were compared across groups using univariate and multivariate logistic regression. The probability of postpartum anxiety and depression was estimated using Kaplan-Meier and Cox proportional hazards regression. Results: The study sample included 55â¯440 birthing people with IDD (including 41â¯854 with intellectual disabilities [ID] and 13â¯586 with autism; mean [SD] age at first delivery, 24.9 [6.7] years) and a random sample of 438â¯557 birthing people without IDD (mean [SD] age at first delivery, 26.4 [6.3] years). People with IDD were younger at first observed delivery, had a lower prevalence of live births (66.6% vs 76.7%), and higher rates of obstetric conditions (gestational diabetes, 10.3% vs 9.9%; gestational hypertension, 8.7% vs 6.1%; preeclampsia, 6.1% vs 4.4%) and co-occurring physical conditions (heart failure, 1.4% vs 0.4%; hyperlipidemia, 5.3% vs 1.7%; ischemic heart disease, 1.5% vs 0.4%; obesity, 16.3% vs 7.4%) and mental health conditions (anxiety disorders, 27.9% vs 6.5%; depressive disorders, 32.1% vs 7.5%; posttraumatic stress disorder, 9.5% vs 1.2%) than people without IDD. The probability of postpartum anxiety (adjusted hazard ratio [AHR], 3.2 [95% CI, 2.9-3.4]) and postpartum depression (AHR, 2.4 [95% CI, 2.3-2.6]) was significantly higher among autistic people compared with people with ID only and people without IDD. Conclusions and Relevance: In this retrospective cohort study, people with IDD had a younger mean age at first delivery, had lower prevalence of live births, and had poor obstetric, mental health, and medical outcomes compared with people without IDD, pointing toward a need for clinician training and timely delivery of maternal health care. Results highlight needed reproductive health education, increasing clinician knowledge, and expanding Medicaid to ensure access to care for people with IDD.
