Background: BRCA1 gene dysfunction seen in epithelial ovarian carcinomas often results from germline mutations, somatic mutations, and promoter methylation. Identification of tumors with loss of BRCA1 protein expression has shown to have therapeutic and prognostic implications. The aim of this study was to determine the expression of BRCA1 protein in epithelial ovarian cancer (EOC) and the associated clinicopathological characteristics. Methods and Results: This was a cross-sectional laboratory-based study that used paraffin-embedded tissue blocks of patients histologically diagnosed with EOC from January 2010 to August 2018. Tissue sections were stained with hematoxylin and eosin (H&E) for histological confirmation and with immunohistochemistry (IHC) using a mouse-derived monoclonal antibody MS110 for BRCA1 protein expression. The association between BRCA1 protein expression and independent variables was determined using Pearson's Chi-square test. A total of 104 tissue blocks from patients with EOC were included in the study with a mean age of 48.7 ± 12.8 years. Serous tumors were the most common which comprised 74.0% (77/104) of all the tumors and majority of them 75.3% (58/77) were high grade. Loss of expression of BRCA1 protein expression was found in 33.7% (33/98) of all the cases. There was no statistically significant association between BRCA1 expression and age of patients, tumor grade, and histological subtype. Conclusion: There is a high expression of altered BRCA1 expression in tissues of EOC. Although it has not shown association with age of patients, histology types, and tumor grade, further studies need to assess its influence of the survival of cancer patients with EOC.

Objective: To investigate the impact of counseling interventions, using face-to-face training vs. mobile app for choosing mode of delivery.

Design: A four-armed, randomized, controlled parallel-design trial. Setting. Ebnesina Private Hospital in Tehran, Iran. Population. Pregnant women, between 24 and 32 weeks of gestation (n = 120).

Methods: Pregnant women were randomly assigned in three psycho-educational intervention groups: (1) motivational interviewing via face-to-face training, (2) information, motivation, and behavioral skills model via face-to-face training, (3) the same model via a mobile application, and (4) usual antenatal care (control group). To assess the face-to-face and mobile app training method on women's self-efficacy and intention in choosing a mode of delivery. Main Outcome Measures. Mode of delivery (Cesarean section).

Results: While all three intervention groups showed significant increases in women's self-efficacy and intentions to choose vaginal delivery, the increase was particularly noticeable among those using mobile applications: Before the intervention, self-efficacy and intention Mean ± SD were 77.1 ± 38.6 (CI-95%: [62.72, 91.60]) and 1.10 ± 0.305 (CI-95%: [0.99, 1.21]), respectively. After the intervention, these scores increased to 99.7 ± 30.7 (CI-95%: [88.27, 111.20]) for self-efficacy and 1.70 ± 0.466 (CI-95%: [1.53, 1.87]) for intention. Although 56.7% of women in the intervention groups expressed a preference for vaginal delivery, only 37.5% ultimately pursued this birthing method.

Conclusions: Brief psycho-educational interventions, particularly technology-driven interventions (mobile apps) can increase the likelihood of women choosing vaginal delivery. To enhance the effectiveness of such interventions, they can be conducted in conjunction with interventions for doctors and healthcare providers. This trial is registered with IRCT20151208025431N7.

Introduction: The physiological process by which the fetus and placenta are delivered from the uterus and pass through the vaginal canal for delivery is known as labor. Induction of labor involves deliberately initiating labor before it occurs naturally, using medical interventions or techniques to stimulate contractions and initiate the birthing process.

Aim: This study aimed to investigate the factors that influence the success of labor induction procedures in Riyadh, Saudi Arabia, from January to April 2023. Subject and Methods. This retrospective chart review was conducted at the National Guard Hospital in Riyadh, Saudi Arabia. Data were collected from the patient chart of those who underwent labor induction from January to April 2023. The collected data were tabulated and cleaned in MS Excel. Final data were transferred to SPSS for subsequent data analysis.

Results: Five hundred and thirty-one pregnant women were analyzed. 52.7% were aged 30 years or below. The most common indication of IOL was post-dated pregnancy (26.2%). 62% were normal deliveries, indicative of IOL success, while 31.1% were cesarean deliveries, indicative of IOL failure. In univariate analysis, women with lower gravidity (≤3) and who had received Propess were associated with cesarean delivery. In a multivariate regression analysis, women who received Prostin and increased parity were identified as the significant independent predictors of IOL success.

Conclusion: IOL's success was dependent primarily on increasing parity and Prostin administration. However, lower gravidity (≤3) and Propess medication could lead to operative procedures among pregnant women. Hence, it is necessary to carefully assess the condition of pregnant women before directing them to IOL.

Considering menstruation as a crucial factor in females' health and fertility, any factor that could change its cycle is important. This study was conducted from April 2021 to October 2022 on females who got 3 doses of vaccines against SARS-CoV-2 through different platforms. The participants were requested to provide the trained experts with any changes regarding menstrual cycles after each dose of the vaccine up to 6 months after the booster shots. The disturbances related to the vaccines were identified by the adverse events committee to find possible associations with the applied vaccines. Of 308 women who participated until the end of the study, 22 (7.1%) complained about at least one abnormality in their menstrual patterns. The most common disturbance was metrorrhagia as 10 (48%) incidences followed by menorrhagia as 6 events (24.2%). Notably, the identified complaints were persistent in 59% of the patients. In addition, 14 studied cases developed COVID-19 infection after menstrual disorders. In these cases, COVID-19 could also play a role in the persistence of postvaccine menstrual disturbances. COVID-19 vaccination could affect menstrual cycle in women with no remarkable previous medical history. More longitudinal studies are required regarding this issue.

Introduction: Hormonal contraceptives (HCs) are used for birth control, menstrual disturbances, and premenopausal syndrome. Most women stop using hormonal contraceptives due to changes in their mood. The evidence regarding the association of hormonal contraception with depression shows mixed results. Therefore, we aim to establish the association between the use of hormonal contraception and depressive symptoms.

Methods: A cross-sectional study was conducted on 326 women of the reproductive age group (15-49 years) attending the family planning unit of the obstetrics and gynecology department of a medical college in Saudi Arabia. Their sociodemographic and medical details along with the current use of any contraceptives (hormonal, nonhormonal, or not using any) with duration were collected. Beck depression inventory-II (BDI-II) was applied to the women to assess for depression along with its severity, and a BDI score of >16 was taken to denote clinical depression. Women were stratified by type of contraceptive used, and its association with depression category was assessed.

Results: A total of 326 consenting eligible women in the age group of 15-49 years were enrolled in the study of which 165 (50.6%) were currently using a hormonal contraceptive and 49 (15.0%) were using a nonhormonal contraceptive and the rest 112 (34.4%) were not using any contraceptives. There was no significant difference in the mean BDI scores (p=0.79) and degrees of depression (p=0.06) between the HC users and HC nonusers. However, individual symptoms of depression such as sadness (p=0.01), reduced libido (p=0.0002), feelings of pessimism (p=0.02), and failure (p=0.003) were found to be significantly higher in the HC users than non-HC users.

Conclusion: We conclude that there was no significant difference in mean depression scores between groups. However, a few individual symptoms of depression were high in HC users suggesting depression as a potential side effect of hormonal contraceptive use.

Background: This study is to compare the time to pregnancy (TTP) between patients with endometriosis and nonendometriosis undergoing in vitro fertilisation (IVF).Material and Methods.This is an observational retrospective cohort study. We included 291 patients (53 with endometriosis and 238 without endometriosis) achieving biochemical pregnancy, whether singleton or multifetal (serum beta-hCG >5 mIU/mL), between 1st January 2014 and 31st March 2020. We excluded patients with incomplete case notes and those declining participation. Time to pregnancy is the interval between the time when infertility was established to the date of confirmed biochemical pregnancy, expressed in months. Endometriosis diagnosis includes any form of endometriosis through surgical confirmation. A statistical analysis was done through the Mann-Whitney U test. Time to pregnancy was assessed through the Kaplan-Meier test. A p value <0.05 is considered statistically significant.

Results: Endometriosis patients had a shorter infertility duration (4 years vs. 5 years, p=0.024). Both groups had similar median age and body mass index at presentation. There was no significant difference in the TTP between endometriosis and nonendometriosis groups (57.7 vs. 70.9 months, p=0.060), further confirmed by a Cox regression test incorporating confounders (IVF protocol (OR: 1.482, 95% CI 0.667-3.292, and p=0.334) and type of the cycle (OR 1.071, 95% CI 0.803-1.430, and p=0.640)). The endometriosis group reached the maximum cumulative pregnancy rate at around 169 months postinfertility diagnosis, whilst the nonendometriosis group at around 255 months postinfertility diagnosis.

Conclusion: Time to pregnancy between endometriosis and nonendometriosis is not significantly different. However, infertility among patients with endometriosis tends to be shorter.

Background: Postpartum haemorrhage is the leading cause of preventable maternal mortality worldwide. Early identification and prompt management of postpartum haemorrhage improve outcomes. Objective assessment of postpartum blood loss is an important step in identifying postpartum haemorrhage. The Brass-V drape and MaternaWell tray have been designed for routine measurement of postpartum blood loss. The perceived utility and acceptability of these devices to the parturients and birth attendants still begged exploring.

Objective: To assess the perceived usefulness and ease of use of a Brass-V drape versus a MaternaWell tray for the collection of postpartum blood loss.

Methods: We conducted a prospective parallel randomised trial, employing a questionnaire to assess the experiences of birth attendants and birthing women who used these devices. The study was conducted at site B midwife obstetric unit in Khayelitsha Cape Town. Pregnant women presenting in early labour were approached for voluntary participation. After informed consent was obtained, participants were randomly assigned to the Brass-V drape or the MaternaWell tray, which the birth attendant placed after the birth of the baby.

Results: There were 63 participants, of which 33 were assigned to the MaternaWell tray and 30 to the Brass-V drape. Birth attendants indicated a desire to use the MaternaWell tray (30 (90%)) or Brass-V drape (26 (87%)) in future deliveries. The parturients were also in favour of the future use of MaternaWell tray (33 (100%)) and Brass-V drape (28 (93%)). Ease of measurement favoured the Brass V-drape, and ease of placement favoured the MaternaWell tray. Five (8%) participants experienced postpartum haemorrhage, two with the MaternaWell tray and three with the Brass-V drape. One parturient required hospital transfer.

Conclusion: The responses of the birth attendants and parturients were positive. The MaternaWell tray has the benefit of reuse and lower cost and is an acceptable alternative to the Brass-V drape. Both devices aid in the early recognition of postpartum haemorrhage.

Objectives: This study aimed to report clinical outcomes of patients with vaginal melanoma (VaM) or vulvar melanoma (VuM) who were treated with immune checkpoint inhibitors (ICI) and discuss the development of immune-related adverse events (irAE).

Materials and methods: This is a retrospective case series of patients diagnosed with VaM or VuM between July 2011 and September 2022 at the University of Virginia, Emily Couric Clinical Cancer Center. Patient demographics, disease characteristics, treatment outcomes, and adverse events were abstracted. The primary outcome was incidence of irAE.

Results: Eight patients were included in this study, four with VaM and four with VuM. Most (n = 6) had local or regional disease at first presentation, and 25% (n = 2) presented with distant metastasis. All patients received a CTLA-4 inhibitor and 75% (n = 6) received PD-1 inhibitor alone or in combination with a CTLA-4 inhibitor. Most (75%, n = 6) patients experienced irAE. Of those who had irAE, 83% (n = 5) required therapy interruption or discontinuation. Most (66%, n = 4) underwent ICI rechallenge of which 75% (n = 3) experienced subsequent irAE. Of all patients in the series, 75% of patients (n = 6) had partial or complete response to ICI.

Conclusion: This series is the first to detail incidence of irAEs and ICI rechallenges in vulvovaginal melanoma. Our findings indicate that while ICIs are effective, their use is associated with significant irAE development. Rechallenge of ICI after irAE is feasible but associated with risk of recurrent/new irAE. Further studies are needed to better quantify this risk.

Aim: To investigate the effect of the triggering method on the results of fresh embryo transfer in patients who underwent gonadotropin-releasing hormone antagonist cycles.

Methods: The study was conducted retrospectively at a university-based tertiary reproductive center. The sample consisted of a total of 295 patients, of whom 111 were in the human chorionic gonadotropin (hCG) trigger group and 184 were in the dual trigger group. The main outcome measure of this study was the live birth rate, and secondary outcomes were the implantation rate, clinical pregnancy rate, miscarriage rate, and good-quality embryo rate.

Results: Patient demographics and baseline characteristics did not significantly differ between the dual and hCG trigger groups. The results also indicated statistically nonsignificant differences between the two groups in terms of the number of oocytes retrieved (p > 0.05), the number of mature oocytes (p > 0.05), and the fertilization rate (p > 0.05). The number of good-quality embryos (p=0.002) was higher in the dual trigger group compared with the hCG trigger group. However, the rates of clinical pregnancy and live births did not significantly differ between the groups (p > 0.05).

Conclusions: Although the number of total and high-quality embryos obtained was higher in the dual trigger group, there were no significant differences between the two groups in terms of pregnancy outcomes. The fresh embryo transfer yielded similar rates of implantation and live births in both trigger groups.

Aim: To explore the potential factors that influence the presentation and recovery of postoperative chylous ascites (CA) in gynecological malignancies.

Methods: We reported two cases of postoperative CA following gynecological surgery and reviewed the clinical features of 140 patients from 16 relevant papers. Patients' clinicopathological characteristics, surgical approach, and management were summarized. The onset and resolution times of postoperative CA in different groups were analyzed separately.

Results: The two patients in our report had recovery after conservative treatments. According to the literature review, the median time of onset of postoperative CA was 5 days (range, 0-75 days) after surgery. The median resolution time was 9 days (range, 2-90 days). Among patients, 87.14% of them had lymphadenectomy during gynecological surgeries, while 92.86% of the patients had resolution after conservative treatments.

Conclusions: Lymphadenectomy during surgery may be relevant to the postoperative CA. Conservative management could be the initial choice for postoperative CA treatment.
