Objective: To externally validate, at the national level, a cumulative risk score for vaginal birth after cesarean (VBAC) success and neonatal morbidity derived from single center data. Methods: We conducted a population based cohort study of all trial of labor after cesarean (TOLAC) attempts among term, singleton deliveries recorded in the Centers for Disease Control and Prevention natality files, 2020 to 2024 (N=477,693). The cumulative risk score (range - 1 to 7 points) incorporated body mass index (BMI) 30 or greater (+1), BMI 40 or greater (+1), induction of labor (IOL; +1), diabetes mellitus (+1), hypertensive disorder (+1), maternal age 40 years or older (+1), gestational age 41 weeks or greater (+1), and prior vaginal delivery (-1). VBAC success rates and neonatal intensive care unit (NICU) admission rates were evaluated across risk strata. Results: The overall VBAC rate was 73.3% (350,340/477,693). The cumulative risk score demonstrated a monotonic relationship with VBAC success: score -1, 90.5%; score 0, 76.4%; score 1, 69.4%; score 2, 62.2%; score 3, 55%; and score 4 or higher, 44.8%. NICU admission rates increased concordantly from 43.8 to 111.1 per 1,000 across strata. Prior vaginal delivery was the strongest individual predictor (VBAC 86.4% vs 62.5%). VBAC rates and TOLAC volume were stable across 2020 to 2024. Conclusion: The cumulative risk score derived from single center data was externally validated in a national cohort of 477,693 TOLAC attempts. The monotonic dose-response relationship between risk score and both VBAC success and NICU admission was confirmed, supporting the use of this score for individualized TOLAC counseling.

Background: Despite significant advancements in obstetric care, the incidence of preeclampsia remains a substantial public health challenge, and effective strategies to prevent the disease progression remain limited, particularly in low-resource settings. N-acetylcysteine (NAC), an antioxidant and glutathione precursor, has demonstrated anti-inflammatory and vasodilatory effects, making it a promising candidate for repurposing. However, robust evidence from well-powered randomized controlled trials is lacking. Objective: This study will evaluate the impact of NAC on the time-to-disease progression in pregnant women with early-onset preeclampsia in Lagos, Nigeria. Methods: This is the study protocol for a proof-of-concept, double-blind, randomized, controlled trial to be conducted between April 2026 to July 2028 at the maternity units of the two teaching hospitals in Lagos, Nigeria. At baseline, n=153 sexually active women aged 18 years or older diagnosed with early-onset preeclampsia at 24 to 34 weeks gestation will be randomised to receive either daily oral tablet containing 600 mg of NAC or a placebo tablet that is matched for appearance and the dosing regimen in addition to standard antenatal care from diagnosis (randomisation) until either 34 weeks gestation or delivery, whichever comes first. The primary endpoint is the time-to-progression (in days) of early-onset preeclampsia to severe disease. The data analysis will be conducted on an intention-to-treat basis. Kaplan-Meier estimates with a Log-rank test will be used to calculate and compare the time-to-disease progression for the treatment groups, while Cox proportional hazard models with a backwards conditional method will be used to compare the primary endpoint between the treatment arms while adjusting for other covariates for precision using hazard ratios (HRs) and 95% confidence intervals (95%CIs). Subgroup analyses will also be performed to assess the differential effects of significant covariates on the impact of NAC on disease progression. Statistical significance will be reported as P<0.05. Discussion: This study will evaluate the efficacy of daily oral NAC compared to placebo in treating pregnant women with early-onset preeclampsia. If proven effective, NAC could offer a safe, affordable, and scalable intervention to reduce the burden of preeclampsia, particularly in resource-constrained settings.

BackgroundPreterm birth is one of the most significant etiologies for neonatal morbidity and mortality. Preterm delivery is classified as iatrogenic preterm delivery and spontaneous preterm delivery. The role of placental pathology is studied. Materials and methodsWe have previously collected placental pathology data with maternal pregnancy and neonatal birth data, and we investigated the role of placental pathology in preterm delivery. Preterm delivery was categorized as late preterm (34-36 weeks), moderate preterm (32 to 33 weeks), and extreme preterm (less than 32 weeks). Neonatal, maternal, placental gross and histologic features, and laboratory parameters were compared across groups using chi-square tests for categorical variables and Kruskal-Wallis tests for continuous variables using various programs in R-package. ResultsTotally 3723 singleton placentas including 3307 term (88.8%) and 416 preterm placentas (11.2%) were examined with maternal pregnancy data and neonatal birth data. There were 614 placentas from patients with preeclampsia/pregnancy induced hypertension (PRE/PIH) (16.5%). Preterm delivery showed significantly lower fetal birth weight, placental weight, and fetal-placental ratio (all p<0.01). Maternal Black race was more prevalent in preterm groups (up to 50.8% in extreme preterm vs. 33.2% in term, p<0.01). Preterm delivery was statistically associated with PRE/PIH and maternal vascular malperfusion (MVM), maternal and fetal inflammatory response (MIR and FIR), and increased pre-delivery white blood count (WBC). Extreme preterm deliveries were markedly associated with intrauterine fetal death (27.5%, p<0.01) and MIR/FIR (56.7%, p<0.01). After excluding PRE/PIH patients, preterm delivery was statistically associated with MIR/FIR and increased WBC. ConclusionsDistinct clinicopathologic profiles exist across preterm subcategories, with MVM predominating in late/moderate preterm and severe pathologic features (including fetal demise and acute inflammation) in extreme preterm. These findings highlight heterogeneous etiologies of preterm delivery.

Objective: To externally validate a risk stratified delivery timing model for nulliparous, term, singleton, vertex (NTSV) cesarean reduction using national data. Design: Population based cohort study of NTSV births in US National Vital Statistics System (NVSS) natality files, 2020 to2024, using logistic regression for cesarean predictors and risk stratified Monte Carlo simulation (10,000 iterations per strategy and risk group) to evaluate delivery timing policies. Setting: All live births in the US recorded in the NVSS natality files. Participants: NTSV patients with term (37+ weeks) pregnancies and complete gestational age and delivery mode data (N=5 776 412). A sensitivity cohort excluded pre 39 week deliveries and pregnancies with preexisting diabetes or hypertension. Exposures: Delivery timing strategies defined by gestational age and labor onset (elective induction at 39, 40, or 41 weeks, or expectant management to 42 weeks), evaluated within maternal age and body mass index (BMI) risk strata (low: age <35 and BMI <30; moderate: age > 35 or BMI > 30; high: age > 35 and BMI > 35). Main Outcomes and Measures: Primary outcome was cesarean delivery, measured as the proportion of deliveries completed by cesarean across gestational ages, labor onset types, and age BMI strata. Secondary outcomes included gestational age specific cesarean rates, area under the receiver operating characteristic curve (AUC) for cesarean prediction, and simulated mean cesarean rates with 95% simulation intervals under four delivery timing strategies within each risk group. Results: The overall NTSV cesarean rate was 26.4%. Cesarean Rates were U shaped across gestational ages, with the lowest rate at 38 weeks (24.9%) and higher rates at 37 weeks (29.8%) and 41 to 42 weeks (28.1 to 28.5%). Risk group distribution was 64.9% low, 33.7% moderate, and 1.4% high. Model AUC was 0.65. Induction had higher cesarean rates than spontaneous labor (29.3% vs 24.2%; odds ratio 1.30, 95% confidence interval 1.29 to 1.30). Monte Carlo simulation favored induction at 39 weeks for high risk patients (59.3%) and expectant management to 41 to 42 weeks for low risk patients (19.1%). Conclusions and Relevance: A risk stratified NTSV labor management model showed external validity in 5.8 million US births and consistently identified risk-specific timing strategies that lowered cesarean rates, supporting individualized delivery timing policies.

Introduction Cesarean delivery accounts for nearly one-third of U.S. births and is associated with substantial maternal morbidity and health care costs. Persistent racial disparities have been documented, yet the structural factors contributing to these differences remain incompletely understood. The extent to which insurance coverage shapes racial disparities in cesarean delivery remains unclear. Objective To evaluate the independent and interactive associations of race/ethnicity and insurance coverage with cesarean delivery in the United States. Methods Population-based retrospective cohort study using singleton live births recorded in the United States Vital Statistics Natality files from 2014 to 2024. Multivariable logistic regression was used to estimate the independent effects of race/ethnicity and insurance status on cesarean delivery, including interaction terms to test effect modification, using national birth certificate data. Models were adjusted for maternal demographics, clinical factors, and temporal covariates. Adjusted odds ratios, predicted probabilities, and absolute risk differences were derived from post-estimation marginal effects. The main outcome measure was cesarean delivery (yes vs no). Results Among 41,543,568 deliveries from 2014 to 2024, 13,312,221 (32.0%) were cesarean deliveries. After adjustment, both race and ethnicity and insurance status were independently associated with cesarean delivery. Compared with non-Hispanic White women, non-Hispanic Black women had higher odds of cesarean delivery (odds ratio [OR], 1.22; 95% CI, 1.22-1.23). Relative to uninsured women, those with private insurance had 59% higher odds of cesarean delivery (OR, 1.59; 95% CI, 1.58-1.60). Significant interaction effects were observed, indicating that insurance coverage modified racial and ethnic differences in cesarean delivery. Non-Hispanic Black women had the highest predicted probabilities across all insurance categories, with the largest absolute disparities observed among uninsured women. Conclusion Racial and ethnic differences in cesarean delivery persist in the United States and are modified by insurance coverage, suggesting that coverage-related differences may contribute to inequities in obstetric care.

We aimed to evaluate disparities in perinatal ICU admissions at an urban medical center and to contextualize these findings relative to national U.S. data provided by the Centers for Disease Control and Prevention (CDC). To do so, we performed a retrospective review of all pregnant and < 6-week postpartum patients admitted to the ICU between October 2023 and June 2025. The cohort included 58 patients: 81% were non-Hispanic Black, and 91% were publicly insured. These local data can be compared to national data, which demonstrate higher rates of severe maternal morbidity (SMM) and ICU admission among Black patients and those insured by Medicaid. In 2023, the U.S. maternal mortality rate was 18.6 per 100,000 live births, down from 22.3 in 2022. However, significant disparities persist, with mortality rates of 50.3 per 100,000 among Black women compared with 14.5 per 100,000 among White women. The most frequently reported indications for obstetric ICU admission include hypertensive disorders of pregnancy, obstetric hemorrhage, and severe underlying medical comorbidities.

Background Caesarean section (CS) rates in Bangladesh have increased rapidly in recent decades. This increase raises concerns about unnecessary procedures and their potential impacts on maternal health. Womens knowledge and positive attitudes toward CS influence delivery preferences and decisions, yet these aspects remain underexplored in Bangladesh. Objectives To assess knowledge and positive attitudes toward CS and to identify factors associated with knowledge and positive attitudes among married women in Bangladesh. Methods The study utilized a cross-sectional sample of married women of reproductive age. A structured questionnaire was used in face-to-face interviews to collect data covering socio-demographic information, obstetric experiences, knowledge, and positive attitudes toward CS. Descriptive statistics, independent sample t-tests, and multiple linear regression analysis were performed to identify factors. Results This study showed that knowledge was lower among rural than urban women; lower among women with a previous CS than those without, and higher among women from husband-headed households. Additionally, respondents without an income source had higher knowledge than those with an income. Regarding attitudes, higher monthly family income was associated with more positive attitudes, while larger family size was associated with lower positive attitudes. Women in husband-headed households had more positive attitudes than those in other-headed households, and women with previous CS had lower positive attitudes. Importantly, higher knowledge scores were strongly associated with more positive attitudes toward CS. Conclusion Strengthening antenatal care, including health, educational, and counselling services, particularly for rural women, larger families, husband-headed households, and women with prior CS, could improve knowledge and promote informed, positive attitudes toward appropriate CS use. Policies and programs should prioritize rural outreach, improve provider-patient communication (especially after a CS), and ensure high-quality counselling, informed consent, and male-inclusive antenatal sessions to support the appropriate use of CS.

1. PurposeSpontaneous preterm birth (sPTB), particularly early preterm birth and mid-trimester loss, remains poorly understood and difficult to predict. The INSIGHT cohort was established to create a deeply phenotyped, longitudinal pregnancy dataset integrating clinical data and biological sampling to investigate the mechanisms of cervical shortening and sPTB, with a focus on linking innate immune responses, the vaginal microbiome, and host biology to identify early biomarkers of risk. 2. Participants2272 pregnant women (8+0 -28+0 weeks gestation) were enrolled as high or low risk of preterm birth based on obstetric history, cervical length, cervical procedures, multiple pregnancy, or Mullerian anomalies. Serial clinical data and biological samples, including cervicovaginal specimens and blood, were collected throughout pregnancy. 3. Findings to dateThe cohort has generated comprehensive multi-omic data, including transcriptomic, microbiome, metabolomic, proteomic, and immune profiling. Key findings demonstrate that maternal plasma cfRNA can predict early sPTB months before clinical presentation, and that integration of cervicovaginal microbiota, metabolites, and host immune markers improves risk prediction and provides mechanistic insight into inflammatory pathways leading to sPTB. 4. Future plansRecruitment concluded in 2023, with final visits occurring in 2024. Ongoing analyses focus on refining predictive models, defining biological subtypes of preterm birth, and translating integrated biomarker panels into clinically scalable risk stratification tools. STRENGTHS AND LIMITATIONS OF THIS STUDYO_LILarge, prospective longitudinal cohort (Strength): Ten years of recruitment with repeat sampling enabled detailed study of biological pathways leading to sPTB. C_LIO_LIBroad risk spectrum with clear definitions (Strength): Inclusion of both high and low-risk women using pre-specified clinical criteria supported robust comparative analyses and biomarker discovery. C_LIO_LIMulticentre NHS recruitment (Strength): Inclusion of several sites, particularly the diverse Lambeth population at St Thomas, enhanced population diversity and external validity. C_LIO_LIHospital-based, high-risk enrichment (Limitation/Strength): Recruitment from specialist preterm birth clinics and secondary/tertiary care may limit generalisability to lower-risk or primary care populations. However, it did ensure many preterm birth events were captured prospectively in this study. C_LIO_LIIncomplete follow-up and limited late sampling (Limitation): Attrition and sampling only up to a prespecified gestation (defined by standard clinical pathway) reduced full pregnancy coverage of longitudinal data.

Background: APOL1 risk alleles are prevalent in individuals of West African ancestry and associated with increased risk of kidney disease. Although preeclampsia disproportionately affects women of Black ethnic backgrounds, evidence linking APOL1 alleles to preeclampsia remains conflicting. Objectives: The purpose of this study was to explore whether maternal APOL1 alleles contribute to preeclampsia risk and associated adverse pregnancy outcomes. Study design: We conducted a nested case-control study of 5210 pregnant women, including 745 preeclampsia cases and 949 controls of Black self-reported ethnicity, 1385 preeclampsia cases and 2131 controls of White self-reported ethnicity. APOL1 G1 and G2 risk alleles were directly genotyped on the Illumina Infinium Global Screening Array. Associations with preeclampsia, early preeclampsia, recurrent preeclampsia, birthweight centiles and gestational age at delivery were examined using regression models assuming a recessive mode of inheritance with adjustment for established risk factors and stratification by self-reported ethnicity and genetically-determined ancestry. Results: Presence of APOL1 risk alleles was almost exclusively observed in women of Black self-reported ethnicity. 168/949 controls (17.7%) and 133/745 cases (17.9%) carried two APOL1 risk alleles, and these women did not have a significantly increased risk of preeclampsia compared to those with zero or one APOL1 risk alleles in adjusted analyses (OR 1.00, 95% CI 0.76-1.29, p=0.972). When restricting analysis to women of Black self-reported ethnicity only, no association was observed between APOL1 genotype and preeclampsia risk (adjusted OR 0.94, 95% CI 0.61-1.25, p=0.673). When restricting analysis to women of pan-African genetically-determined ancestry only, also no association was observed between APOL1 genotype and preeclampsia risk (adjusted OR 1.00, 95% CI 0.76-1.32). No associations were found between number of APOL1 risk alleles and early preeclampsia, recurrent preeclampsia, birthweight centile or gestational age at delivery after adjustment for established risk factors and stratification by self-reported ethnicity or genetically-determined ancestry. Conclusions: Maternal APOL1 risk alleles do not independently influence preeclampsia risk or related adverse outcomes in a multi-ethnic pregnancy study. Future studies should examine whether fetal APOL1 genotypes, alone or in interaction with maternal genotypes, contribute to preeclampsia risk.

Background: Placental function is associated with congenital heart defects (CHD), frequently presenting with malperfusion lesions and small-for-gestational-age size. However, placental villous vasculature in the setting of CHD is understudied. This study evaluated differences in placental, neonatal, and maternal outcomes among maternal/infant dyads with versus without CHD. Methods: We conducted a gestational age- and fetal sex-matched retrospective case control study using specimens prospectively collected by a local biobank. Neonatal outcomes included birthweight, placental weight, and their ratio (placental efficiency). We estimated the proportion of placental villous tissue comprised of fetal vascular endothelial cells (%FVE) using anti-CD34 immunohistochemistry and a pixel count algorithm. Placental weight multiplied by %FVE estimated the grams of placental tissue comprised of villous vasculature (placental vascular index). Maternal outcomes included hypertensive disorders of pregnancy and gestational diabetes. We compared cases and controls using linear and logistic regression adjusted for maternal smoking and cold ischemia time. Stratified analyses examined associations by preterm birth status. Results: Dyads (n=34 with CHD, n=34 without CHD) had maternal age of 29.4 +/- 4.9 years and were 35.6 +/- 4.0 gestational weeks at delivery. Groups had similar placental, neonatal, and maternal parameters. Among preterm neonates, we observed small-to-moderate effect sizes indicating lower placental weight, %FVE, and placental vascular index, and higher placental efficiency, in CHD cases. Among term neonates, moderate effect sizes suggested lower birthweight, placental weight, and placental vascular index in CHD cases. Conclusions: Though differences between groups were not significant, moderate effect sizes suggested that placental vascularization was lower among preterm neonates with CHD.

While pregnancy intentions are increasingly recognised as complex and dynamic, unexpected pregnancies are often studied cross-sectionally, and a life course perspective is lacking. This study aimed to explore the salient themes and patterns in 1) the life course trajectories of individuals experiencing an unexpected pregnancy and 2) the transition surrounding an unexpected pregnancy. We conducted semi-structured qualitative interviews with 22 individuals (15 women and 7 men) experiencing unexpected pregnancies. Two interviews were held: during pregnancy and six months after childbirth. The respondents' life course trajectories were mapped using visual timelines and the transition was explored using Schlossberg's transition theory. Interviews were thematically analysed in an iterative process: applying open coding to three interviews followed by thematic coding and comparison of themes within and across life course trajectories. Life course trajectories varied considerably, distinguished by the absence or presence of critical life events, with patterns characterised by clustering life events within the domains of family, mental health or frequent residential mobility. The transition process of unexpected pregnancy was characterised by three patterns of adjustment - shift (instant adjustment), spark (triggered adjustment) and unfolding (ambiguous adjustment) - in which respectively, all life course trajectories, trajectories with clustering of life events and mainly stable trajectories were present. This study contributes to the literature through the unfolding pattern, showing that adjustment to unexpected pregnancy may be an ambiguous process that is not finished when the baby has arrived, especially if individuals have strong aspirations in light of a relatively stable life course.

Objective: To determine the incidence and clinical characteristics of surgical complications during pregnancy in women with a history of bariatric surgery. Design: A nationwide, prospective, population-based cohort study. Setting: High-risk obstetric care in Belgium: 67.6% of maternity units participated, covering 65% of all births in the study period. Participants: Pregnant women with a history of bariatric surgery presenting with a surgical complication (internal hernia, intussusception, volvulus or adhesions; anastomotic ulcer or abscess; gastric band slippage; or incisional hernia) between January 2021 and December 2022. Results: Thirty-three women experienced 35 surgical complications. Internal herniation was most common (n=25), predominantly following Roux-en-Y gastric bypass. Mean gestational age at diagnosis was 27+6 weeks. All women underwent surgical exploration within 24 hours; bowel resection was required in two cases. Caesarean section occurred in 48.5%, with 13 preterm births and one neonatal death. One woman required intensive care. No maternal death occurred. Conclusion: Surgical complications following bariatric surgery in pregnancy are uncommon but carry significant obstetric risks. All observed complications occurred after procedures involving intestinal rerouting, predominantly Roux-en-Y gastric bypass. Prompt surgical management was associated with low maternal morbidity and no mortality, but frequently resulted in preterm birth and emergency caesarean section. These findings highlight the need for a low threshold for surgical evaluation of abdominal pain in pregnant women with previous bariatric surgery and suggest that procedure type is relevant when counselling women of reproductive age.

Preconception weight loss by metabolic-bariatric surgery (MBS) improves maternal-fetal outcomes, but little is known about its impact on offspring growth and health. The preconception bariatric surgery and child health outcomes (POSIT) study aims to estimate the effects of maternal MBS-induced preconception weight loss on infant and childhood body size, growth, and related outcomes. This report presents the methods used to construct the POSIT cohort and its baseline characteristics. This retrospective cohort study sampled members from a United States healthcare system aged 18 and older with a singleton, live birth to create three study groups: 1) a treatment group including women who underwent preconception MBS and subsequently became pregnant (n=1,374); 2) a control group matched to the MBS pre-surgery body mass index (BMI) (pre-surgery controls, n=13,740); and 3) a second control group matched to the MBS post-surgical, pre-pregnancy BMI (pre-pregnancy controls, n=13,740). MBS and pre-surgery BMI controls showed slight imbalances in that pre-surgery BMI controls were on average ~6 months younger, had 0.6 lower BMI (44.5 kg/m2) at the time of their pregnancy and were more likely to have become pregnant in earlier years than the MBS group prior to surgery. MBS and pre-pregnancy controls had comparable age (mean {+/-} SD 33 {+/-} 5 years), pre-pregnancy BMI (33 {+/-} 6 kg/m2), and year of delivery. Following matching, the MBS group had similar socioeconomic and health disparities as the pre-surgery control group, and both were worse than pre-pregnancy control group. Pregestational maternal comorbidity index improved after MBS and matched the pre-pregnancy controls. Upon extraction of offspring growth patterns and mediation analyses of maternal weight loss and metabolic responses to MBS, study findings will investigate effects of preconception weight loss by MBS on short- and long-term child health outcomes. Results will guide future studies focusing on improving maternal preconception weight and maternal-fetal outcomes.

Objectives: Accurate classification of menopausal stage is fundamental to midlife health research. Although the Stages of Reproductive Ageing Workshop (STRAW+10) criteria provide gold-standard criteria, their application in research settings is inconsistent. Classification challenges are compounded in individuals without observable menstrual cycles due to surgical or contraceptive-induced amenorrhoea. The Reproductive Ageing in Women (RAW) Questionnaire and accompanying classification Framework was developed and validated to improve consistency and inclusivity when classifying menopausal stage. Study design: A multi-phase study was conducted between May 2022 and July 2025. Phase one involved questionnaire development based on STRAW+10 and the Menopause-Specific Quality of Life Questionnaire. Phase two assessed content validity via expert review (n=3). Phase three evaluated face validity using think-aloud interviews and focus groups (n=14). Phase four validated RAW within a cross-sectional cohort study (n=156), and assessed construct validity (n=30), test-retest reliability (6-21 days; n=128; Kendall's Tau-b and Cohen's kappa), and biological validity using follicle stimulating hormone (FSH). Results: Feedback supported clarity, relevance and usability, with refinements improving inclusivity for surgical and contraceptive-induced amenorrhoea. Construct validity demonstrated consistent application of classification criteria. Questionnaire classification showed 93% concordance with self-identified menopausal status in the construct sample and 87.8% agreement within the cohort sample. Test-retest reliability was excellent ({tau}, p=0.940, p<0.001). Follicle stimulating hormone levels differed across RAW-classified stages (p<0.001), with 96.1% concordance between RAW pre and postmenopausal classifications and FSH thresholds. Conclusions: Prioritising menstrual characteristics while incorporating age and symptom criteria improves methodological consistency and inclusivity in menopausal stage classification. Longitudinal validation is warranted to assess temporal sensitivity across the menopausal transition.

Objective: To investigate, in the context of endometriosis management, the perceptions of patients and healthcare professionals regarding hormonal treatment options. Design: Qualitative study using semi-structured focus group methodology. Setting: University hospitals and academic research center. Subject(s): Patients with endometriosis (n=20) and healthcare professionals (n=13) involved in their care. Intervention(s): Not applicable Main Outcome Measure(s): Focus group topics investigated representations on the concept of treatment effectiveness, emotion associated to this medical management and the perceived impact of these therapies on patient-professional and patient-environment relationship. Result(s): We highlighted a discrepancy between patients and doctors regarding the concept of efficacy of hormonal therapies. Long-term amenorrhea is the main priority for healthcare professionals, whereas pain reduction remains the immediate wait for patients. Interviewed patients reported a lack of listening and empathy, a shared-information deficit as regards treatment options and side-effects and a need to involved partner and family in care. These factors contribute to communication issues between patients and doctors and appear to contribute to significant mental burden on both sides. Among healthcare professionals, mental burden appears to arise primarily from the resource-intensive demands of endometriosis management, whereas among patients it is driven more by the need to take an active role in their own care to compensate for insufficient information provided by physicians. Conclusion: In this study, we highlighted the ambiguities surrounding the concept of therapeutic efficacy of hormonal therapies and collected several factors to try to improve shared-decision-making process in the management of endometriosis. This is designed to help us create a shared decision-making tool in the near future.

Prenatal depression is a substantial contributor to maternal morbidity, and screening is an entry point to psychiatric assessment and treatment during pregnancy. Following updated guidelines and quality metrics for prenatal depression screening, we evaluated whether screening uptake differed by preferred language within a large U.S. healthcare system. We used electronic health record data to identify a retrospective cohort of deliveries at or beyond 20 weeks gestation in 2019-2024. We used logistic regression with a language-year interaction to estimate the adjusted marginal probabilities of screening by language preference. Among 99,526 pregnancies (82,632 individuals), screening increased substantially over time but increases differed across language groups (p<0.001). In 2019, screening probabilities were similar (English 0.50; Spanish 0.48; Another Language 0.50). By 2024, probabilities diverged (English 0.81; Spanish 0.66; Another Language 0.71). Unequal screening uptake can systematically under-identify prenatal depression among patients with non-English language preference, with implications for equitable access to psychiatric care.

Background: Reusable menstrual products provide sustainable and cost effective alternatives to disposable sanitary products; however, their adoption remains limited, even among healthcare professionals. Objectives: To assess awareness, knowledge, perceptions, and utilisation of reusable menstrual products among female medical students and healthcare professionals, and to identify predictors of willingness and use. Design: Cross sectional analytical study. Setting: An online survey was conducted among female medical students and healthcare professionals in Nigeria. Participants: A total of 203 female respondents aged 15 to 55 years. Intervention: Not applicable. Primary Outcome Measures: Utilisation of reusable menstrual products and willingness to adopt their use. Secondary Outcome Measures: Awareness, knowledge, perceptions, and barriers. Methods: Data were collected using a structured questionnaire and analysed using descriptive statistics, chi square tests, and logistic regression. Results: Awareness was high (96.06%), but utilisation was low, with 5.42% ever using and 4.43% currently using reusable products. About 31.53% were willing to use them. Respondent type was not associated with willingness (p = 0.735), although healthcare professionals had higher knowledge (p = 0.024). Positive perception predicted willingness (AOR = 7.58, 95% CI: 3.18 to 18.03, p < 0.001). Good knowledge (AOR = 14.96, p = 0.014) and increasing age (AOR = 1.28, p = 0.004) predicted utilisation. Conclusion: Despite high awareness, utilisation remains low. Perception influences willingness, while knowledge drives use. Targeted behavioural and educational interventions are needed. Keywords: Menstrual hygiene, reusable menstrual products, menstrual cup, sustainability, healthcare professionals

Background/Objectives: This study aimed to evaluate the efficacy and outcomes of operative hysteroscopy for the removal of endometrial polyps and assess the procedure's impact on pain experienced by patients. The research was conducted to determine whether the minimally invasive nature of operative hysteroscopy compromises patient comfort when compared with diagnostic hysteroscopy. Methods: The study was conducted at the Gynecology and Obstetrics Clinic of Ba[g]clar Training and Research Hospital over a period of four months. It included 200 women over 18 years of age who were indicated for hysteroscopy. Operative hysteroscopy procedures were performed without the use of a speculum, cervical dilation, anesthesia, or analgesic agents, emphasizing the procedure's minimally invasive approach. Pain assessment utilized the Visual Analog Scale (VAS). Patients were stratified into two groups--those undergoing operative and those undergoing diagnostic hysteroscopy--to compare outcomes and pain scores. Results: The study found that operative hysteroscopy successfully removed 85.1% of the lesions, primarily polyps. There was no significant difference in pain scores between the operative and diagnostic hysteroscopy groups, indicating that the minimally invasive procedure does not increase patient discomfort. Conclusions: Operative hysteroscopy is an effective and tolerable procedure for the removal of endometrial polyps, with high success in complete lesion removal and without significantly impacting the pain experienced by patients. The findings support the use of operative hysteroscopy as a first-line treatment option for endometrial polyps, underscoring the importance of patient selection and the need for further studies on long-term outcomes related to fertility and recurrence.

BackgroundMaternal protein restriction results in a 28% reduction in nephrogenic cells and nephron units in rodent offspring by the 17th day of gestation compared to adequate protein intake. AimsThe present study investigates the association between growth factor expression and some developmental pathways that contribute to nephron reduction during embryonic and fetal development. Experimental DesignPregnant C57BL/6-Tg and C57BL/6J mice were assigned to either normal protein intake (NP-17%) or low protein intake (LP-6%) groups. Body weight of male offspring and kidney growth factor expression were assessed on gestation days (GD) 14 and 18. ResultsOn GD 14, LP pups exhibited a 4% higher body mass (0.1035 g) compared to NP pups (0.0995 g, p = 0.005). By GD 18, LP pups demonstrated a 4% decrease in body mass (0.939 g, p = 0.03) and a 10% increase in the number of cells per metanephric cap area. Three genes (Csf2, Il1b, Il2) were downregulated, while seven genes (Bmp2, Csf3, Fgf8, Gdnf, Bmp7, Fgf3, Ntf3) were upregulated. By GD 14, phagophores and autophagosomes in the ureteric bud increased by 197%, with further increases observed by GD 18. Bcl-2 expression increased significantly in ureteric bud cells, and mTOR activity was elevated by GD 18. ConclusionEarly gestational protein restriction modifies renal growth factor gene expression, influencing cell proliferation and autophagy, and may contribute to reduced nephron numbers by the 18th day of gestation. HIGHLIGHTSO_LIThis study examines the effects of a low-protein diet during pregnancy in mice and demonstrates a significant reduction in embryo-fetal body weight between gestational days 14 and 18. C_LIO_LIProtein restriction induces a distinct cellular pattern in the mesonephros, with a 21% increase in CAP cells at gestational day 14 (GD14), followed by a decrease by gestational day 18 (GD18) compared to offspring from mothers on a normal protein diet. C_LIO_LIAdditionally, increased expression levels of key growth factors essential for kidney development were observed at GD 14, comparing LP with NP intake during pregnancy. C_LIO_LISeven genes were upregulated (Gdnf, Bmp2, Bmp7, Tgf, Fgf8, Fgf3, Csf3, Ntf3), while three genes were downregulated (Csf2, Il1b, Il2). C_LIO_LIOverall, these findings indicate that gene regulation, autophagy, and mTOR signaling mechanisms significantly influence nephron numbers in response to gestational protein restriction beyond the 18th day of gestation.

OBJECTIVE: Anthropometric data are critical in paediatric care, routinely assessed during clinical visits, and available in electronic health records (EHRs). We describe the feasibility of extracting anthropometric data from heterogeneous EHR systems of Swiss childrens hospitals, evaluate their availability and quality, and assess the cohorts representativeness of the general population. METHODS: In this multicentre study (SwissPedGrowth), we retrospectively collected EHRs from patients <20 years who visited hospitals in Basel, Bern, Geneva, Lausanne, Luzern, St. Gallen, or Zurich between 2017-2023. Sociodemographic, administrative, and clinical information from EHRs were provided in a standardized way by a paediatric national data stream (SwissPedHealth), including the Swiss Neighbourhood Index of Socioeconomic Position (Swiss-SEP). We counted anthropometric recordings per visit to describe availability and used a self-developed and an existing (growthcleanr) algorithm to investigate data quality. To assess representativeness, we compared sociodemographic characteristics between SwissPedGrowth and the general paediatric population in Switzerland, computed standardized differences (effect size: 0.2 small, 0.5 medium, 0.8 large), and weighted the study population to reduce differences. RESULTS: We included 477,531 patients and 2,171,633 hospital visits; 54% boys, 71% Swiss, mean Swiss-SEP 65 (SD: 11), and median age at visit 6.3 [IQR: 2.3, 11.8] years. Height recordings were available for 20% of the visits, weights for 43%, and head circumferences for 5%, with better availability for inpatient stays than outpatient or emergency visits. Combining the self-developed and existing algorithm, 4% of heights and 3% of weights were flagged as outliers and 29% of heights and 31% of weights as carried forward from previous visits or same day duplicates. Sociodemographic differences between SwissPedGrowth and the general population were small or small-to-medium and disappeared after weighting. CONCLUSION: SwissPedGrowth demonstrates feasibility of extracting high-quality anthropometric data for paediatric growth research, but challenges regarding completeness and harmonization of EHR data across Swiss hospitals remain.
