Transcriptomic Analysis of the Aged Nulliparous Mouse Ovary Suggests a Stress State That Promotes Pro-Inflammatory Lipid Signaling and Epithelial Cell Enrichment.

Ovarian cancer (OC) incidence and mortality peaks at post-menopause while OC risk is either reduced by parity or increased by nulliparity during fertile life. The long-term effect of nulliparity on ovarian gene expression is largely unknown. In this study, we describe a bioinformatic/data-mining analysis of 112 coding genes upregulated in the aged nulliparous (NP) mouse ovary compared to the aged multiparous one as reference. Canonical gene ontology and pathway analyses indicated a pro-oxidant, xenobiotic-like state accompanied by increased metabolism of inflammatory lipid mediators. Up-regulation of typical epithelial cell markers in the aged NP ovary was consistent with synchronized overexpression of Cldn3, Ezr, Krt7, Krt8 and Krt18 during the pre-neoplastic phase of mOSE cell cultures in a former transcriptome study. In addition, 61/112 genes were upregulated in knockout mice for Fshr and for three other tumor suppressor genes (Pten, Cdh1 and Smad3) known to regulate follicular homeostasis in the mammalian ovary. We conclude that the aged NP ovary displays a multifaceted stress state resulting from oxidative imbalance and pro-inflammatory lipid signaling. The enriched epithelial cell content might be linked to follicle depletion and is consistent with abundant clefts and cysts observed in aged human and mouse ovaries. It also suggests a mesenchymal-to-epithelial transition in the mOSE of the aged NP ovary. Our analysis suggests that in the long term, nulliparity worsens a variety of deleterious effects of aging and senescence thereby increasing susceptibility to cancer initiation in the ovary.

Is Parity a Risk Factor for Late Preterm Birth? Results from a Large Cohort Study.

Most preterm births occur in the late preterm period. While prematurity-related adverse outcomes are significantly diminished when birth occurs during this period, these infants are still at increased risk of complications. Parity affects the incidence of obstetric complications. The purpose of this study was to determine whether parity impacts the risk of spontaneous late preterm birth (SLPTB) and associated complications. A retrospective observational cohort study was conducted. Patients were divided into three study groups according to parity. The primary outcome was the rate of SLPTB in each group. Secondary outcomes were unplanned cesarean delivery (UCD), prolonged third stage of labor respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), intraventricular hemorrhage (IVH), neonatal hypoglycemia, duration of NICU admission, neonatal death, and composite adverse neonatal outcome (CANO). Primiparas were more likely to have SLPTB, UCD, and CANO compared to multiparas (2.6% vs. 1.9% OR 1.5 [1.3-1.7] p < 0.01) (4.1% vs. 1.3% OR 2.7 [1.2, 5.9] p < 0.01) (8.5% vs. 4.2 OR 2.1 [1.3-3.5] p = 0.002) and grandmultiparas (2.6% vs. 1.7% OR 1.4 [1.2-1.5] p < 0.001) 8.5% vs. 4.4% OR 2.0 [1.1, 3.8], p = 0.01) but no difference in UCD compared to grandmultiparas (4.1% vs. 3.3% OR 1.2 [0.6-2.7] p = 0.28). Primiparas are at increased risk of SLPTB and UCD, and this is accompanied by an increased risk of adverse neonatal outcomes.

Endovascular Treatment of Pelvic Venous Congestion Syndrome in Nulliparous Patients-Preliminary Results of 10 Years of Experience.

PURPOSE: The aim of this article is to present our experience with minimally-invasive treatment for nulliparous patients with pelvic venous congestion syndrome (PVCS) with special attention to anatomical considerations, procedural and clinical outcome. MATERIALS AND METHODS: In this retrospective, monocentric study, 21 patients with PVCS treated from January 2014 to June 2023 were included. The preprocedural imaging evaluation of PVCS was based on color Doppler ultrasound, contrast-enhanced CT and/or MRI. In all cases insufficient ovarian veins and/or internal iliac branches were occluded with coils and sclerosant. Procedural and clinical outcomes were measured 30 and 90 days after the procedure. RESULTS: Average duration of pelvic pain was 44.8 ± 54.2 months (from 6 to 200) with the mean VAS-recorded pain intensity of 8.5 ± 1.1 (range from 7 to 10 where 0 was "no pain" and 10 "worst pain possible"). Most common symptoms included dysmenorrhea, dyspareunia and dysuria. Complete embolization was observed in in all cases. Targeted vessels included left ovarian vein (13/21, 62%), both ovarian veins (7/21, 33%) and left pudendal with left ovarian (1/21, 5%). Residual PVCS was noted in 1 patient. Mean VAS at 90-days after the procedure was 2.4 ± 1.4 (range from 0 to 6, p < 0.001). Nineteen patients (90%) were satisfied with the clinical outcome (13 "very satisfied", 6 "satisfied") and reported improvement in quality of life. Two patients (9.5%) reported to be "neutral" as the VAS reduction was less than 50%. CONCLUSION: Our study confirms that endovascular coil embolization is safe and effective in treatment of nulliparous patients with PVCS that provides very high rate of clinical success and overall satisfaction.

The Role of Passive Descent and Epidural Analgesia in Outcomes Associated With Prolonged Pushing Among Nulliparous Individuals in Midwifery Care.

INTRODUCTION: Efforts to reduce primary cesarean birth may include supporting longer second stages of labor. Although midwifery-led care is associated with lower cesarean use, little has been published on associated outcomes of prolonged second stage (≥3 hours of pushing) for nulliparous individuals in US hospital-based midwifery care. Epidural analgesia and the role of passive descent in midwifery-led care are also underexplored in relation to the second stage. In this study, we report the incidence of prolonged second stage stratified by epidural analgesia and/or passive descent. Secondary aims included calculating the odds of cesarean birth, obstetric anal sphincter injury (OASI), postpartum hemorrhage (PPH), and neonatal complications. METHODS: Data were collected prospectively from a single academic center in the United States from 2012 through 2019. Our cohort analysis of labors attended by midwives for nulliparous, term, singleton, and vertex pregnancies included both descriptive and inferential statistics comparing outcomes between prolonged versus nonprolonged pushing groups. We stratified the sample and quantified second stage outcomes by epidural analgesia and by use of passive descent. RESULTS: Of the 1465 births, 17% (n = 247) included prolonged pushing. Cesarean ranged from 2.2% without prolonged pushing to 26.7% with prolonged pushing. Fetal malposition, epidural analgesia, and longer passive descent were more common among those with prolonged active pushing. Despite these factors, neither odds for PPH nor poor neonatal outcomes were associated with prolonged pushing. Those with more than one hour of passive descent in the second stage who also had prolonged active pushing had lower odds for cesarean but higher odds for OASI relative to those who had little passive descent before pushing for more than 3 hours. DISCUSSION: Prolonged pushing occurred in nearly 2 of 10 nulliparous labors. Fetal malposition, epidural analgesia, and prolonged pushing were commonly observed with longer passive descent, cesarean, and OASI. Passive descent in these data likely reflects individualized midwifery care strategies when pushing was complicated by fetal malposition or other complexities.

Endometrial Cancer in Reproductive-Aged Females: Etiology and Pathogenesis.

Endometrial cancer is the most common gynecologic malignancy in developed countries, and the incidence is rising in premenopausal females. Type I EC is more common than Type II EC (80% vs. 20%) and is associated with a hyperestrogenic state. Estrogen unopposed by progesterone is considered to be the main driving factor in the pathogenesis of EC. Studies show that BMI > 30 kg/m2, prolonged duration of menses, nulliparity, presence of polycystic ovarian syndrome, and Lynch syndrome are the most common causes of EC in premenopausal women. Currently, there are no guidelines established to indicate premenopausal patients who should be screened. This review aims to synthesize current data on the etiology, risk factors, presentation, evaluation, and prognosis of endometrial cancer in this population.

Is it possible to predict massive bleeding in nulliparous women with placenta previa?

Abstract Objective We evaluated risk factors to determine if there were specific risk factors that could predict massive bleeding in nulliparous women with placenta previa. Methods The participants were classified into two groups. Women with a calculated blood loss ≥ 1,000mL were included in the massive bleeding group. Women without any signs or symptoms related with hypovolemia or with a calculated bleeding volume < 1,000 mL were categorized into the non-massive bleeding group. Results There were 28 patients (40.6%) with massive bleeding and 41 cases (59.4%) with non-massive bleeding. The calculated blood loss and number of cases that required red cell transfusions were statistically different between the groups (< 0.005 and 0.002, respectively). There were no statistically significant differences in terms of maternal or fetal factors, placental location, or delivery characteristics between the two groups. Conclusion We could not determine the predictive features for massive hemorrhage based on clinical features, delivery features, or placental location.

Cesariana primária em nulíparas: fatores de risco em hospital público universitário / Primary cesarean delivery in nulliparous women: risk factors at a public university hospital

Objetivo: Identificar fatores determinantes para risco de cesariana primária em nulíparas. Métodos: Estudo de coorte prospectivo desenvolvido em hospital público universitário. Foram incluídas todas primíparas atendidas na emergência obstétrica de dezembro/2006 a junho/2007. Informações sociodemográficas e doenças prévias foram obtidas na admissão; o desfecho principal foi a via de parto. Para análise estatística utilizou-se o modelo de regressão de Poisson e as variáveis com significância de associação ≤ 0,2 entraram no modelo múltiplo. Resultados: As variáveis determinantes da cesariana primária entre nulíparas foram: apresentação fetal não cefálica (RR=2,8; IC95 %=1,9 ­ 4,2); emergências obstétricas (RR=2,4; IC95 %=1,7 ­ 3,2); macrossomia fetal presumida (RR=1,9; IC95%=1,2 ­ 3,2); doenças fetais (RR=1,6; IC95%=1,2 ­ 2,2); idade gestacional igual ou maior de 40 semanas (RR=1,5; IC95%=1,1 ­ 2,0); distúrbios hipertensivos (RR=1,33; IC95%=1,01 ­ 1,76) e idade materna (RR=1,05; IC95%=1,03 - 1,07). Conclusões: Os resultados indicaram que os principais fatores determinantes para cesariana primária são condições potencialmente modificáveis. A apresentação fetal não-cefálica pode ser alterada com utilização mais frequente da versão cefálica externa; a idade gestacional ≥ 40 semanas, com datação criteriosa da gestação e protocolos previamente definidos para indução do parto; a macrossomia fetal presumida, com treinamento em avaliação clínica e/ou ecográfica do peso fetal no termo (AU)

Aim: To identify the factors associated with the increased incidence of primary cesarean delivery among nulliparous women. MethodS: Prospective cohort study at a public university hospital in Porto Alegre, Brazil. All primiparous women who gave birth at Hospital de Clínicas de Porto Alegre between December 2006 and June 2007 were eligible. Sociodemographic and clinical data were obtained on admission. The primary endpoint was mode of delivery. Results: a Poisson regression analysis showed that the determinants for primary cesarean section in this population of nulliparous women were: non-cephalic presentation (RR=2.8; 95%CI=1.9- 4.2); obstetric emergencies (RR=2.4;95%CI=1.7 ¬­ 3.2); suspected macrosomia (RR=1.9; 95%CI=1.2 ­ 3.2); fetal disease (RR=1.6; 95%CI=1.2 ­ 2.2); gestational age ≥40 weeks (RR 1.5; 95%CI=1.1 ­ 2.0); hypertensive disorders (RR=1.33; 95%CI=1.01 ­ 1.76) and maternal age (RR=1.05; 95%CI=1.03 ­1.07). Conclusions: this study shows that the main factors behind the incidence of cesarean sections in nulliparous women can be solved without a cesarean. The noncephalic presentation can be changed with external cephalic version; gestational age ≥ 40 weeks can be avoided with careful timing of pregnancy and pre-defined protocols for labor induction; and assumed fetal macrosomia can be minimized with training in clinical and/or sonographic fetal weight assessment (AU)
