Background: To investigate the expression of serum Growth differentiation factor 15 (GDF-15) and examine its correlation with systolic and diastolic blood pressure in third-trimester pregnant women with hypertensive disorders of pregnancy (HDP).

Methods: This cross-sectional study included 60 patients with HDP in the third trimester (HDP group) and 50 healthy pregnant women (control group). Clinical characteristics were collected and serum GDF15 levels were measured.

Results: Serum GDF-15 levels were significantly elevated in the HDP group compared to controls. Moreover, Serum GDF-15 levels were positively correlated with both systolic blood pressure and diastolic blood pressure in the HDP group.

Conclusions: Serum GDF‑15 levels may be associated with the severity of HDP.

Background: Luteal phase support (LPS) with progesterone is a generally accepted practice after controlled ovarian stimulation, although the best protocols for LPS have been debated. We aimed to compare the efficacy of vaginal micronised progesterone tablets and 8% vaginal progesterone gel for LPS using real-world data.

Methods: This retrospective study included 459 in vitro fertilisation/intracytoplasmic sperm injection cycles performed at a university hospital from 2005 to 2019. All cycles were followed by fresh day 3 embryo transfer (ET). Either progesterone tablets or gel was used for LPS. To control the conditional probability of progesterone tablets or gel use, doubly robust inverse probability weighting composed of inverse-probability-of-treatment weighting (IPTW) and regression adjustment (RA). IPTW was performed based on the covariate balancing propensity score (CBPS).

Results: Progesterone tablets were administered in 65 cycles, and progesterone gel was administered in 394 cycles. Women who used progesterone tablets were more likely to be older (36 vs. 34 years), have primary infertility (78.5% vs. 61.4%), use gonadotropin-releasing hormone antagonist (60.0% vs. 43.2%), and have fewer retrieved oocytes (seven vs. nine) and transferred embryos (two vs. three) than participants who used progesterone gel. After IPTW-CBPS and RA analysis for the above covariates, the adjusted odds for clinical pregnancy in women who used progesterone tablets were 1.10 times compared with women who used progesterone gel; however, the 95% confidence interval did not reach statistical significance (0.96-1.26).

Conclusions: Clinical pregnancy was comparable between vaginal micronised progesterone tablets and vaginal progesterone gel for LPS in fresh day 3 ET cycles.

Background: Research on fertility preservation among women diagnosed with lymphoma is very limited. We aimed to assess the receipt of fertility preservation information and use of fertility preservation among women diagnosed with lymphoma.

Methods: This was a retrospective, single-centre study. Patients with Hodgkin and non-Hodgkin lymphoma were screened from the electronic medical records of individuals who attended the Haematology Department at the study site between 2000 and 2018 and were followed-up for obstetric outcomes and onset of menopause until December 2023.

Results: Forty-three patients had available electronic health records. Overall, 13 (36.1%) of the 36 patients ≤45 years old received fertility preservation counselling; it was more frequent among nulliparous women (11/23, 47.8%), women aged ≤35 years (11/26, 42.3%), and those diagnosed in the latest study period from 2015 to 2018 (9/16, 56.3%). Of the 13 patients who were informed about fertility preservation, 2 patients refused this intervention, and fertility preservation was contraindicated for 3 patients, leading to a total of eight women who underwent fertility preservation strategies: six underwent ovarian cortex cryopreservation, and two underwent oocyte vitrification. Among the participants aged ≤45 years, 10 (27.8%) had at least one live birth after diagnosis. Fifteen (34.9%) of the 43 participants exhibited amenorrhoea after the initiation of chemotherapy, including 4 women ≤35 years of age. The median (range) age at menopause in this series was 45 (27-50) years.

Conclusion: Even though the situation appears to have improved in recent years, we are far from reaching the target of all women with lymphoma who are of reproductive age receiving fertility preservation counselling before initiating chemotherapy.

Background: The aims of this study are to investigate the causal relationships between sleep traits and the risk of gestational diabetes mellitus (GDM), preterm birth, and foetal growth restriction (FGR).

Methods: This two-sample Mendelian Randomisation (MR) study was conducted from May to June 2024 to investigate the associations between seven sleep traits and GDM, preterm birth, and FGR. The study utilised data from large-scale genome-wide association study datasets, and specifically focused on individuals of European descent. The main analysis employed inverse-variance-weighted MR, with sensitivity analyses conducted to mitigate potential pleiotropy-induced biases. Additionally, multivariable MR analysis was conducted to adjust for potential confounding factors.

Results: Genetically predicted excessive daytime sleepiness (OR 13.67; 95% CI, 1.03-180.59; p = 0.047) and sleep apnoea (OR 1.29; 95% CI, 1.00-1.65; p = 0.049) were found to be associated with a higher risk of GDM. No sleep trait was associated with either preterm birth or FGR. These results were robust across various sensitivity analyses. In the multivariable MR analysis, adjusting for body mass index (BMI) and smoking, the genetically instrumented excessive daytime sleepiness (OR 14.58; 95% CI 1.67-127.36; p = 0.015) and sleep apnoea (OR 1.30; 95% CI 1.02-1.64; p = 0.030) were consistently associated with an increased GDM risk.

Conclusions: This study suggests a causal relationship between both excessive daytime sleepiness and sleep apnoea to the development of GDM. Excessive daytime sleepiness and sleep apnoea demonstrate promise as potentially preventable risk factors for GDM.

Background: Intrauterine adhesion (IUA) often recurs after surgery, and hysteroscopic follow-up is essential for early detection. However, the ideal timing for follow-up is uncertain. This study examines how different follow-up timings affect IUA recurrence after surgery.

Methods: All patients (142) who received hysteroscopic surgery in our hospital between 1 January 2021 and 31 November 2024 were retrospectively recruited using the convenience sampling method. The patients were retrospectively divided into two groups based on the timing of postoperative hysteroscopic follow-up. Group A (n = 71) underwent a routine follow-up at 3 months postoperatively, whereas Group B (n = 71) had an early follow-up at 14 days, with additional follow-ups after each menstrual cycle for 3 months. The primary outcomes measured were uterine cavity morphology and menstrual improvement 3 months post-surgery. The recovery of uterine cavity morphology and menstrual improvement after 3 months of follow-up were compared between the two groups.

Results: There was a significant positive correlation between the recovery of uterine cavity morphology and the number of postoperative hysteroscopies in Group B (r = 0.335, P < 0.001). After 3 months following the operation, the improvement of menstruation (Z = -3.423, P = 0.001) and the recovery of uterine morphology (Z = -3.741, P = 0.001) in Group B were better than those in Group A, and the difference was statistically significant.

Conclusion: Early and regular hysteroscopy in patients with IUA undergoing hysteroscopic adhesion separation is effective in restoring uterine cavity morphology, preventing re-adhesion and improving menstruation.

Background: An estimated 230 million girls and women are living with female genital mutilation (FGM) which causes ongoing physical and psychological harm. This review aims to explore what is known about FGM and incontinence, including the underexamined implications for women's health, and identify gaps in the literature.

Methods: A comprehensive database search was conducted using MEDLINE, CINAHL Plus, APA Psych Info, AMED, Child Development and Adolescent Studies, and PubMed. To gather all relevant complications of FGM, no restrictions were imposed on date or study type. Themes were identified by organising the 20 eligible articles by symptom type.

Results: The findings indicate that urological symptoms such as dribbling incontinence, slow micturition, urgency, stress incontinence and overactive bladder are prevalent among women who have undergone FGM. Additional complications include fistulas, pelvic organ prolapse, somatic symptoms, and urinary tract infections. The impact of FGM and incontinence on quality of life and daily activities remains under-explored, with the lived experiences of affected women largely unreported.

Conclusions: FGM has multiple urogynaecological consequences, with more severe forms causing increased symptoms and associated complications. This review highlights the need for further research into the biopsychosocial impacts of FGM and incontinence to provide evidence-based support for affected women.

Background: Endometrial carcinoma is a clinically complex gynaecologic malignancy exhibiting significant molecular heterogeneity. This heterogeneity manifests as marked variability in clinical outcomes and heterogeneous therapeutic responses to emerging treatment modalities, particularly to immune checkpoint inhibitors. Metabolic reprogramming has been implicated in tumour progression and immune evasion in endometrial carcinoma. However, the prognostic implications of metabolism-related genes and their interaction with the tumour immune microenvironment remain insufficiently characterised.

Methods: RNA-seq and clinical data of endometrial carcinoma were downloaded from The Cancer Genome Atlas (TCGA) database, along with a metabolism-related gene set (MRGs) curated from the Msigdb database. Differential expression analysis was conducted to identify differentially expressed metabolism-related genes (DE-MRGs), which were subsequently analysed to evaluate their expression patterns and prognostic significance in uterine corpus endometrial carcinoma. Functional enrichment was performed via GO and KEGG analysis. The CIBEROSRT computational algorithm was employed to quantify immune infiltration characteristics and their correlation with MRGs. Furthermore, an external GEO dataset (GSE17025) was employed to validate hub gene expression.

Results: A total of 49 differentially expressed MRGs were identified in endometrial carcinoma. Functional analyses showed enrichment in retinol and tyrosine metabolism pathways. Two hub genes, LIPG and DDC, were significantly associated with overall survival (p = 0.01 and p = 0.0015, respectively). Multivariate analysis confirmed DDC as an independent prognostic factor (p < 0.001). Immune profiling revealed higher infiltration of regulatory T cells (p = 0.005) and M0 macrophages (p = 2.6 × 10^-16) in tumours. LIPG and DDC exhibited significant correlations with various immune cell populations.

Conclusion: Our study analysed the expression and prognostic relevance of MRGs of endometrial carcinoma. We validated the prognostic value of MRGs and their potential to offer novel insights into prognostication and personalised treatment strategies for endometrial carcinoma.

Background: Ectopic pregnancies represent a potentially life-threatening medical emergency, with 95% being tubal. This meta-analysis aimed to identify early predictors for single-dose methotrexate (MTX) treatment failure in tubal pregnancies.

Methods: A literature search was conducted across several databases from their inception to December 2023, with references in the selected studies manually reviewed. 14 studies involving 2,804 patients were included in this meta-analysis.

Results: The results revealed that higher serum beta-human chorionic gonadotropin (β-hCG) levels on Day 1 (SMD = 1.25, 95% CI 0.73-1.77), foetal cardiac activity presence (OR = 12.64, 95% CI 3.15-50.75), adnexal mass presence (OR = 4.66, 95% CI 2.02-10.74), yolk sac presence (OR = 5.35, 95% CI 2.33-12.27), thicker endometrium (MD = 1.74, 95% CI 0.30-3.19), more number of previous ectopic pregnancies (MD = 0.21, 95% CI 0.13-0.30), history of pelvic inflammatory disease (PID) (OR = 3.97, 95% CI 2.02-7.79), higher progesterone levels on Day 1 (SMD = 0.22, 95% CI 0.07-0.36), a higher 48-hour pre-treatment increment in serum β-hCG percentage (MD = 11.46, 95% CI 2.95-19.98), and a higher percentage of serum β-hCG change from Day 4 to Day 0/1 (SMD = 2.58, 95% CI 1.02-4.14) were early predictive factors for treatment failure of tubal pregnancy with the MTX single-dose regimen.

Conclusions: This review clarifies early predictive factors for treatment failure with the MTX single-dose regimen in tubal pregnancies. High-risk tubal pregnancies likely to fail MTX monotherapy could be identified earlier, allowing for personalised intervention measures to be implemented at an early stage to prevent harm and improve treatment outcomes.

Background: Pregnancy and childbirth are vulnerable periods for women's mental health, with common occurrences of postnatal depression (PPD), postpartum post-traumatic stress symptoms (PP-PTSS) and postnatal severe fear of childbirth (PP-FOC). While previous trauma is linked to higher rates of postpartum psychological difficulties, the mechanisms and variations by parity and sociodemographic factors remain poorly understood. The aim of this study was to compare the prevalence of PPD symptoms, postnatal post-traumatic stress disorder (PP-PTSD), PP-PTSS and PP-FOC between women with a history of trauma and those without. Additionally, the study aimed to analyse the prevalence of previous trauma and postnatal mental health problems in subgroups of primi- and multiparous women, and to investigate how trauma influenced mental health in relation to sociodemographic characteristics.

Methods: This was a cross-sectional study including 619 women who had given birth at five maternity clinics in Sweden. Data for the survey were collected online using validated instruments to measure PPD, PP-PTSD, PP-PTSS and PP-FOC. Data were analysed using Chi-squared tests, independent t-tests and uni- and multivariable regression.

Results: Women with a trauma history (n = 298) showed significantly higher rates of PPD (26% vs. 13%) and PTSD (5% vs. 2%) than those without a trauma history (n = 321). Previous trauma, age and parity significantly influenced postnatal outcomes, with trauma having the most substantial impact.

Conclusions: A history of trauma is correlated to higher risk of postpartum mental health problems, while previous births may offer some protection, especially against PP-PTSS and PP-FOC. Early identification and targeted support for women with trauma histories are recommended.
