Objective: Gremlin 1 and 2 regulate oocyte primordial follicle transition in animal models. The main objective of this study is to measure the blood levels of Gremlin 1 and 2 in the women with Polycystic Ovary Syndrome (PCOS). We also aimed to evaluate the association of these markers with hormonal and biochemical parameters of PCOS as interrupted folliculogenesis in those women is related to metabolic dysfunction. Material and methods: Fifty women with PCOS were diagnosed according to Rotterdam criteria, and thirty age-matched female controls were included in this prospective study. Gremlin 1 and 2 levels along with hormonal and metabolic parameters were compared between PCOS and control groups. Results: Serum Gremlin 1 levels were significantly higher in the PCOS group than in the control group (p = .001). Gremlin 2 levels were similar between the groups. Besides, there was a significant positive correlation between Gremlin 1 and insulin levels, Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) and waist to hip ratio (WHR) (r = 0.305; r = 0.297; r = 0.303, respectively). Conclusion: Our data suggest that Gremlin 1 may be the key regulator in the pathogenesis of PCOS. In future, Gremlin 1 may be a novel therapeutic target for the treatment of PCOS.

Aim: To compare the rates of surgical wound infection in women who have undergone cesarean delivery with subcuticular skin closure with polyglactin 910 or polypropylene. Methods: Between April 2018 and October 2018, patients who had undergone a cesarean delivery for any reason were randomized with polyglactin 910 or polypropylene for subcuticular skin closure. Participants were evaluated for wound complications on day 7 and 30 postoperatively. The primary outcome was surgical site infection within the first 30 days following delivery. In addition, factors affecting surgical site infections were analyzed by binary regression. Results: A total of 220 women who had undergone cesarean delivery were randomized and 213 were included in the final analysis. The groups were similar in terms of demographic characteristics and perioperative features. No statistically significant difference was observed between the groups in terms of wound complications or superficial site infections (8.3% in the polypropylene group versus 10.6% in the polyglactin 910 group, p = .642). Similarly, no difference was observed between the groups in terms of other wound complications. A binary logistic regression analysis indicated that superficial wound site infection was not affected by gravidity, BMI, duration of operation, repeated or unplanned cesarean delivery. Conclusion: It was observed that surgical site infections and other wound complications in skin closures with polyglactin 910 were similar to those with polypropylene.

Introduction: Severe fetal anemia may cause cardiac ischemia, reduced contractility, and dysfunction. The purpose of our study is to evaluate right ventricular myocardial performance index (MPI) before and after intrauterine transfusion (IUT) in patients who underwent this procedure because of fetal anemia due to Rh-D alloimmunization. Materials and methods: This prospective cohort study was conducted between January 2018 and June 2019 at Kanuni Sultan Suleyman Research and Training Hospital, Istanbul, Turkey. The pregnant women who were applied IUT because of fetal anemia due to Rh-D alloimmunization in our perinatology clinic were included in the study. Fetal right ventricular MPI before and 24 h after IUT were evaluated. Results: A total of 28 IUTs were performed in 17 pregnant women during the study period. The isovolumetric contraction time (ICT) and isovolumetric relaxation time (IRT) values measured before IUT, were found to be significantly longer compared to the ICT and IRT values measured after IUT. The MPI values measured after transfusion was found to be higher than before transfusion. Conclusions: The fetal right ventricular MPI increases 24 h after IUT. This increase in the right ventricular MPI might be used as a marker for predicting adverse fetal outcomes following IUT.

Purpose: To describe clinical and virologic outcomes after topical 5% imiquimod for VaIN (vaginal intraepithelial neoplasia) within routine clinical practice, including the assessment of available post-treatment high-risk HPV status, and to evaluate its relationship with treatment outcomes. Methods: In this retrospective-cohort study, twenty patients with histologically confirmed VaIN (low-grade VaIN = 10, high-grade VaIN = 10) were evaluated between October 2020 and October 2022. The treatment varied based on the initial VaIN grade. The primary endpoint was complete response, defined as negative cytology and/or benign follow-up biopsy. Secondary endpoints included partial response (downgrading from high-grade to low-grade), persistence/progression, adverse events, and available post-treatment high-risk HPV status. Results: Among seventeen evaluable patients, a complete response was observed in 69.2% (9/13) imiquimod-treated patients. In high-grade VaIN imiquimod-treated patients, complete response was observed in 66.7% (6/9), while 33.3% (3/9) downgraded to low-grade VaIN on biopsy as a secondary outcome, with no persistence over a median follow-up of 24 months. Low-grade VaIN showed 75% clearance with either imiquimod or observation at a median follow-up of 24 months. In one low-grade imiquimod-treated, persistent HPV16 was observed, and the lesion progressed to high-grade VaIN; however, no invasive cancers were observed during follow-up. Adverse events related to imiquimod were mild; there were no discontinuations. Among baseline high-risk HPV positive imiquimod-treated patients, post-treatment follow-up HPV testing was available in a limited subset group, and clearance was confirmed in 44% (4/9) among those with follow-up testing and presented descriptively as exploratory. Conclusions: In this single-center retrospective cohort, outcomes after topical 5% imiquimod are reported as observed findings. Complete and partial responses were observed in high-grade VaIN with acceptable tolerability and no invasive events at available intermediate follow-up (median 24 months). Post-treatment HPV testing provided complementary virologic information alongside clinical outcomes, consistent with recommendations incorporating HPV testing into VaIN follow-up, and longer surveillance is required to assess long-term oncologic outcomes.

Objective: The aim of the study is to objectively evaluate the effects of Loop Electrosurgical Excision Procedure (LEEP) on women’s sexual function using a validated questionnaire. Methods: This pre-post survey design study was conducted at a tertiary referral hospital gynecological oncology clinic. 80 sexually active patients who had undergone LEEP because of abnormal cervical cytology results between October 2018 and December 2018 were included. Participating patients answered the Female Sexual Function Index (FSFI) questionnaire before undergoing LEEP and at 3 and 6 months after the procedure. The FSFI questionnaire consists of 19 multiple choice questions and it evaluates the following six aspects of female sexuality: arousal, lubrication, desire, orgasm, satisfaction, and pain. 9 patients were excluded for not coming to the follow-up appointments. Patients who had any systemic or psychological disease were excluded in order to avoid any additional variables that could affect sexual function. Results: Arousal, lubrication, desire, orgasm, satisfaction, and pain were evaluated in 71 patients. There was no statistical difference in sexual desire, lubrication, sexual satisfaction, and pain in between follow-up results and the baseline scores. However, there was a significant decrease in patients’ orgasm scores and degree of arousal in the follow-up results compared to the baseline scores. Conclusion: Parameters such as orgasm and the degree of arousal, which are strongly connected with a patient’s physical and psychological well-being, are affected by the procedure. We believe detailed information, psychological support, and even psychiatric consultation can have a beneficial effect on patients. Further studies with a larger sample and a control group and a longer follow-up interval should be performed to assess the effect of psychological precautions and to avoid sexual function disorders resulting from LEEP.

Background: Adnexal masses are common in women across different age and hormonal states: pregnancy, premenopause, and postmenopause. Ovarian carcinoma, a malignancy arising in the adnexa, poses significant health risks. While malignancy risk increases with age and postmenopausal status, current methods for stratifying borderline cases remain inadequate, potentially leading to over- or undertreatment that may affect fertility or survival. Methods: This retrospective study was conducted with 318 adult women who were diagnosed with adnexal masses and underwent surgery at a university hospital between 2020 and November 2023. Patient data were retrieved from the hospital’s electronic medical record system. Routinely measured preoperative serologic parameters—carbohydrate antigen (CA)125, CA19-9, CA15-3, carcinoembryonic antigen (CEA), Alpha-fetoprotein (AFP), Lactate dehydrogenase (LDH), and fibrinogen-to-albumin ratio (FAR) levels—were analyzed alongside final histopathological results. No procedures outside routine clinical practice were performed. Diagnostic performance of each marker was evaluated using receiver operating curve (ROC) analysis. Results: A total of 318 patients with adnexal masses were analyzed. The FAR levels were significantly elevated in malignant compared to borderline and benign groups (p < 0.001), and FAR alone showed 47% sensitivity and 91% specificity for borderline tumors, whereas CA125 showed 70% sensitivity and 85% specificity. Multivariate models combining FAR, CA125, and CA15-3 achieved the highest diagnostic accuracy, with superior AUCs compared to single biomarkers. Conclusions: FAR is a simple, accessible inflammatory marker that complements CA125 by enhancing specificity. Combination of multiple markers with the highest sensitivity and specificity, together with FAR, may reduce the risk of both false negatives, offering a more balanced and accurate diagnostic tool for preoperative stratification of borderline tumor cases.
