    Analyzing the performance of ChatGPT in answering inquiries about cervical cancer
    (Wiley, 2025) Yurtcu, Engin; Ozvural, Seyfettin; Keyif, Betul
    Objective: To analyze the knowledge of ChatGPT about cervical cancer (CC). Methods: Official websites of professional health institutes, and websites created by patients and charities underwent strict screening. Using CC-related keywords, common inquiries by the public and comments about CC were searched in social media applications with these data, a list of frequently asked questions (FAQs) was prepared. When preparing question about CC, the European Society of Gynecological Oncology (ESGO), European Society for Radiotherapy and Oncology (ESTRO), and European Society of Pathology (ESP) guidelines were used. The answers given by ChatGPT were scored according to the Global Quality Score (GQS). Results: When all ChatGPT answers to FAQs about CC were evaluated with regard to GQS, 68 ChatGPT answers were classified as score 5, and none of ChatGPT answers for FAQs were scored as 2 or 1. Moreover, ChatGPT answered 33 of 53 (62.3%) CC-related questions based on ESGO, ESTRO, and ESP guidelines with completely accurate and satisfactory responses (GQS 5). In addition, eight answers (15.1%), seven answers (13.2%), four answers (7.5%), and one answer (1.9%) were categorized as GQS 4, GQS 3, GQS 2, and GQS 1, respectively. The reproducibility rate of ChatGPT answers about CC-related FAQs and responses about those guideline-based questions was 93.2% and 88.7%, respectively. Conclusion: ChatGPT had an accurate and satisfactory response rate for FAQs about CC with regards to GQS. However, the accuracy and quality of ChatGPT answers significantly decreased for questions based on guidelines.

    Comparison of the Efficacies of Sacrospinous Ligament Fixation and Laparoscopic Lateral Suspension in the Treatment of Apical Prolapse: 24-Month Follow-Up Results
    (Imr Press, 2025) Yurtcu, Engin; Keyif, Betul; Sarigedik, Burcu; Basbug, Alper; Tinelli, Andrea
    Background: Pelvic organ prolapse (POP) significantly impacts the quality of life, particularly in older women with a history of vaginal deliveries. Although conservative treatments provide some symptom relief, surgical interventions are more effective for managing POP. This study compares the outcomes and effectiveness of sacrospinous ligament fixation (SSLF) and laparoscopic lateral suspension (LLS) surgeries in the treatment of POP.Methods: This retrospective comparative cohort study included patients with symptomatic stage 2 or higher apical POP, treated at a tertiary hospital in Turkey between April 2021 and June 2022. Patients were treated with either SSLF or LLS surgeries and underwent preoperative and postoperative evaluations using the Prolapse Quality of Life (P-QoL) questionnaire and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Patients were divided into two groups: SSLF (n = 47) and LLS (n = 44). The primary outcome was the rate of anatomical failure, while secondary outcomes included improvements in functional capability and quality of life.Results: The study found that the rate of postoperative anterior compartment failure was significantly lower in the LLS group compared to the SSLF group (p = 0.005). The success rate of LLS for apical prolapse was 100%, compared to 93.6% for SSLF. In the posterior compartment, SSLF demonstrated a higher success rate (86.2%) than LLS (68.5%). Both procedures improved P-QoL scores and the PISQ-12 subscales; however, a significant improvement in total PISQ-12 scores was observed only in the LLS group (p = 0.009).Conclusions: Both SSLF and LLS are effective in treating POP and enhancing quality of life. However, LLS demonstrated higher success rates for anterior and apical prolapse, while SSLF was more effective in addressing in posterior compartment defects.

    An Exploratory Study of Serum Vasorin Levels in Polycystic Ovary Syndrome: A Novel Potential Biomarker for Diagnosis and Pathogenesis
    (Mdpi, 2025) Keyif, Betul; Yurtcu, Engin; Basbug, Alper; Yavuzcan, Ali; Goynumer, Fikret Gokhan
    Objective: This study aims to investigate the potential role of vasorin as a novel biomarker in the pathogenesis of polycystic ovary syndrome (PCOS) by evaluating serum vasorin levels in women diagnosed with PCOS. Methods: A prospective study was conducted at D & uuml;zce University Faculty of Medicine between March and July 2024, including 92 women with PCOS, diagnosed based on the 2003 Rotterdam criteria, and 68 age- and BMI-matched healthy controls. Serum vasorin levels were measured using an enzyme-linked immunosorbent assay (ELISA) and compared between the two groups. Additionally, correlations between vasorin levels and metabolic, inflammatory, and hormonal parameters were analyzed. Results: Women with PCOS had significantly lower serum vasorin levels (median: 0.70 pg/mL) compared to the control group (median: 2.36 pg/mL, p < 0.001). No significant correlation was found between vasorin and metabolic or hormonal parameters in the PCOS group. However, a weak positive correlation with prolactin was observed in the control group (r = 0.264, p = 0.030). Although vasorin is involved in inflammatory and oxidative-stress pathways, its association with insulin resistance and lipid metabolism remains unclear based on this study. Receiver Operating Characteristic (ROC) curve analysis demonstrated a high diagnostic performance for vasorin in distinguishing PCOS from healthy individuals (AUC = 0.918, p < 0.001, 95% CI: 0.869-0.967). The optimal cutoff value for vasorin (1.285 pg/mL) yielded 92.6% sensitivity and 87.0% specificity. Conclusions: These findings suggest that vasorin may serve as a promising biomarker for PCOS, potentially linking hormonal dysregulation, inflammatory responses, and ovarian dysfunction. However, further validation is required through longitudinal studies, multi-center cohorts, and mechanistic investigations. Additionally, comparative assessments with established biomarkers such as anti-M & uuml;llerian hormone (AMH) and androgen levels are warranted to determine vasorin's diagnostic and prognostic utility in clinical practice.

    Exploring the Inflammatory Basis of Endometrial Polyps: Clinical Implications of Hematological Biomarkers in a Retrospective Study
    (Mdpi, 2025) Keyif, Betul; Yavuzcan, Ali; Yurtcu, Engin; Basbug, Alper; Duzenli, Fatmanur; Keyif, Elif; Goynumer, Fikret Gokhan
    Background/Objectives: Endometrial polyps (EPs) are common benign endometrial lesions often linked to abnormal uterine bleeding and infertility. While hormonal factors play a key role in their development, recent studies suggest a potential inflammatory component. This retrospective study aimed to assess systemic inflammatory markers, including mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), in EP patients. Methods: A total of 180 patients were classified into three groups: EP (n = 60), chronic endometritis (n = 60), and control (n = 60). Preoperative hematological parameters were retrieved from medical records. Group comparisons were performed using one-way ANOVA, with Tukey's post hoc test applied when significant. Multinomial logistic regression was used to identify independent predictors of EPs. Results: MPV and PLR were significantly higher in the EP group compared to other groups (p = 0.014 and p = 0.015, respectively), while NLR differences were not statistically significant (p = 0.086). Logistic regression identified MPV (p = 0.004) and PLR (p = 0.045) as independent predictors of EPs. Conclusions: These findings suggest that systemic inflammation may contribute to EP development, with MPV and PLR serving as potential inflammatory biomarkers. Further prospective studies with histopathological validation are needed to clarify the role of inflammation in EP pathogenesis.

    Gestational Hydronephrosis: A Retrospective Analysis of the Clinical Outcomes of Ureteral Stent Placement Versus Conservative Treatment
    (Mdpi, 2025) Baba, Dursun; Yurtcu, Engin; Ayvacik, Burak; Kucuk, Yusuf Salih; Taskiran, Arda Taskin; Ozel, Mehmet Ali; Balik, Ahmet Yildirim
    Background and Objectives: Gestational hydronephrosis (GH) is a physiological condition commonly observed during pregnancy, resulting from hormonal effects and mechanical compression of the ureters by the enlarging uterus. Although often asymptomatic, GH can cause urinary stasis, recurrent infections, and renal function impairment in symptomatic cases. The optimal management of such cases remains controversial, especially regarding the role of ureteral stent placement. This study aimed to compare clinical outcomes-including renal function, inflammatory markers, and obstetric parameters-in pregnant women with symptomatic GH who underwent ureteral stent placement versus those managed conservatively. Materials and Methods: We conducted a retrospective cohort study at D & uuml;zce University Hospital between 2020 and 2024, including 40 pregnant women diagnosed with symptomatic GH. The patients were divided into the following two groups: those who received a ureteral stent (n = 20) and those who were managed with conservative treatment (n = 20). Conservative management included hydration therapy, acetaminophen-based analgesia, and close clinical monitoring. The parameters assessed included serum creatinine, estimated glomerular filtration rate (GFR), inflammatory markers (C-reactive protein, erythrocyte sedimentation rate, and white blood cell count), urinary findings, obstetric outcomes, and postpartum complications. Statistical significance was set at p < 0.05. Results: Gestational age at diagnosis was significantly higher in the stent group (29.1 +/- 3.2 weeks) than in the non-stent group (27.1 +/- 3.5 weeks; p = 0.045), possibly reflecting increased mechanical compression in later pregnancy. Renal function parameters (serum creatinine and GFR), inflammatory markers (CRP, ESR, and WBC count), and obstetric outcomes (birth weight, Apgar scores) showed no significant differences between groups (p > 0.05). Interestingly, gestational diabetes mellitus (GDM) was more prevalent in the non-stent group (20% vs. 5%; p = 0.042), although no significant differences were found in fasting glucose levels. Conclusions: Ureteral stent placement in symptomatic GH does not appear to significantly improve renal function or obstetric outcomes. However, it may provide symptom relief in select patients with persistent or severe discomfort. Given the limitations of retrospective data and a small sample size, further prospective studies with larger cohorts and quality-of-life assessments are warranted to optimize management strategies and enhance patient-centered care.

    Implementation of enhanced recovery in women undergoing cesarean delivery improves breastfeeding and maternal perioperative outcomes
    (Georg Thieme Verlag Kg, 2025) Birden, Duygu Yildiz; Basbug, Alper; Yurtcu, Engin; Kale, Ibrahim
    Objective The study aimed to evaluate delivery outcomes after implementation of the Enhanced Recovery After Surgery (ERAS) protocol in patients delivered by cesarean section (CD). Materials and Methods This randomized controlled prospective study was conducted on 78 pregnant women who underwent CD with the ERAS protocol and 78 pregnant women who under went standard perioperative care. We compared the time to first flatus, visual pain score (VAS), the success of breastfeeding, time to initiation of breastfeeding, time to return to daily activities, hemoglobin values, the incidence of postoperative nausea and vomiting, hospital readmission rates, postoperative wound infection rates, incidence of postpartum blues, and the need for blood transfusion between two groups. Results Time to first flatus, VAS score, time to initiation of breastfeeding, and time to return to activities of daily living were significantly lower in the ERAS group (p<0.001 for all). The rate of successful breastfeeding was significantly higher in the ERAS group (p<0.001). Both groups were similar in terms of other parameters. Conclusion Implementation of ERAS after CD shortens the breastfeeding initiation time and increases rates of successful breastfeeding. ERAS protocols implemented in CD improve perioperative outcomes such as visual pain score and time to resume daily activities.

    Is There Any Effect of Change in Pre-Wash and Post-Wash Semen Parameters on the Success of Intrauterine Insemination?
    (Mdpi, 2024) Yavuzcan, Ali; Yurtcu, Engin; Keyif, Betuel; Osmanlioglu, Seyma
    (1) Background: We aimed to investigate the effect of change in pre-wash and post-wash semen parameters on intrauterine insemination (IUI) success in a homogenous study group. (2) Methods: IUI cycles conducted at an infertility clinic were included in this study. Patient records were examined retrospectively. Delta sperm count (per mL) was calculated as [pre-wash sperm count (per mL)-post-wash sperm count (per mL)]. Delta Total progressive motile sperm count (TPMSC) was also calculated as (post-wash TPMSC-pre-wash TPMSC). (3) Results: No statistically significant difference was detected in terms of Delta sperm count (p = 0.38), and Delta TPMSC (p = 0.76) regarding the clinical pregnancy rate (CPR). There was no statistically significant difference between CPR (+) and CPR (-) groups in terms of post-wash sperm count, TPMSC, TPMSC >= 10 x 10 ?, TPMSC >= 5 x 10 ? (p = 0.65, p = 0.79, p = 0.49, p = 0.49, respectively). The live birth rate (LBR) showed no statistically significant differences except for a pre-wash TPMSC >= 10 x 10 ? (p = 0.02). Through the performed ROC analysis, no statistically significant cutoff value could be set for the pre-wash TPMSC. (4) Conclusions: There is only a pre-wash TPMSC >= 10 x 10 ? that showed a significant role in the success of IUI, even when considering all other pre-wash and post-wash semen parameters. Delta sperm count and Delta are not useful markers for IUI success.

    (Duzce Univ, Fac Medicine, 2025) Teberik, Ceren; Keyif, Betul; Yurtcu, Engin; Basbug, Alper; Goynumer, Fikret Gokhan
    Objective: This study aimed to evaluate the usefulness of intrapartum transperineal ultrasonographic (ITU) parameters in predicting delivery mode. Method: This prospective study included 104 pregnant women inAactive labor with ruptured membranes at D & uuml;zce University Health Application and Research Center from April 2023 to April 2024. ITU measured the angle of progression (AoP), head-perineum distance (HPD), and midline angle (MLA). These parameters were compared with digital vaginal examinations and delivery outcomes. Results: Of the participants, 93 (89.4%) had spontaneous vaginal deliveries (SVD), 6 (5.7%) had operative vaginal deliveries (OVD), and 5 (4.8%) had cesarean sections (C/S). AoP1 and AoP2 were significantly higher in the SVD group compared to OVD and C/S groups (p<0.001). The Delta AoP was significantly lower in the OVD group (p=0.044). HPD1 and HPD2 were significantly higher in the C/S group (p=0.031 and p=0.041, Arespectively). MLA1 and MLA2 were significantly lower in the SVD group (p=0.002 and p=0.001, Arespectively). Conclusions: ITU is a valuable tool in predicting delivery mode. AoP, HPD, and MLA measurements provide objective and reliable data to assist clinicians in labor management. Further research with larger sample sizes is needed to validate these findings and establish standardized protocols for clinical use.

    Predictive Value of Volumetric Measurements of Fetal Adrenal Glands for Preterm Birth: A Case-Control Study
    (Imr Press, 2024) Basbug, Alper; Yurtcu, Engin; Keyif, Betul; Kaya, Aski Ellibes; Sungur, Mehmet Ali; Goynumer, Fikret Gokhan; Hatirnaz, Safak
    Background: To investigate whether fetal adrenal gland volume (AGV) and fetal zone volume (FZV), important components of the fetal adrenal gland, differ between women who have term and preterm births, and to determine whether these two parameters can be used to predict premature birth. Methods: A total of 238 pregnant women at 24-28 weeks of gestation were included in this case-control study. The fetal AGV and FZV were ultrasonographically evaluated, and corrected AGV (cAGV) and corrected FZV (cFZV) were assessed with adjustments for estimated birth weight. Receiver operating characteristic (ROC) curves were used to assess the ability of AGV, FZV, cAGV, and cFZV to predict preterm birth. Results: Ultrasound exams on 220 term fetuses and 18 preterm fetuses showed that preterm fetuses exhibited higher AGV (p = 0.039), FZV (p = 0.001), cAGV (p = 0.001), and cFVZ (p = 0.001) compared to term fetuses. Conclusions: These results demonstrated that term and preterm fetuses differ in their AGV and FZV within this study population. The data generated by 3D sonography between 24 and 28 weeks of gestation may be beneficial for predicting premature birth. However, larger prospective studies with a larger sample size of preterm births are needed to validate these findings.

    The role of incretins in gestational diabetes: a case-control study on the impact of obesity
    (Bmc, 2024) Yurtcu, Engin; Keyif, Betul; Yilmaz, Gamze; Erkilinc, Selcuk; Akkaya, Hatice; Ozgu-Erdinc, A. Seval
    Background This study aimed to evaluate the role of serum Glucagon-Like Peptide-1 (GLP-1), Glucagon-Like Peptide-2 (GLP-2), and Glucose-Dependent Insulinotropic Polypeptide (GIP) levels in relation to obesity and gestational diabetes mellitus (GDM) in pregnancy. Methods A case-control study was conducted, including 96 pregnant women with singleton pregnancies who underwent the Oral Glucose Tolerance Test (OGTT) for GDM diagnosis during the 24th-28th weeks of gestation. Blood samples were collected for measuring GLP-1, GLP-2, GIP, and fasting glucose. Statistical analyses included receiver operating characteristic (ROC) curves and correlation analysis. Results Among the 96 women, no significant difference in age was observed between the groups, but Body Mass Index (BMI) was significantly higher in GDM-O (Gestational Diabetes Mellitus-Obese) and non-GDM-O groups (p < 0.001). GLP-1 had an area under the curve (AUC) of 0.666 (95% CI: 0.553-0.778, p = 0.005) for diagnosing GDM. The optimal GLP-1 cutoff was 815.86 ng/mL, with 65% sensitivity and 77% specificity. A significant correlation was found between GLP-2 and GIP (r = 0.289, p = 0.004), but no significant correlations were observed between GLP-1 and other peptides or gestational age (p > 0.05). Conclusions Impaired secretion of GLP-1, GLP-2, and GIP likely contributes to the pathogenesis of GDM. GLP-1 may serve as a potential biomarker for diagnosing GDM.

    Unmasking metabolic clues: adipsin, irisin and osteopontin as biomarkers in polycystic ovary syndrome and their impact on metabolic dynamics: a case-control study
    (Via Medica, 2025) Duzenli, Fatma Nur; Yurtcu, Engin; Keyif, Betul; Basbug, Alper
    Objectives: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age, often associated with metabolic alterations.This study assessed serum levels of adipsin, irisin, and osteopontin in patients with PCOS and examined their correlations with metabolic parameters. Material and methods: A case-control studywas conducted involving 96 women with PCOS and 80 healthy controls. Serum levels of adipsin, irisin, and osteopontin were measured; demographic, clinical, and metabolic characteristics were evaluated. Results: Patients with PCOS were significantlyyoungerthan controls (p < 0.001).The PCOS group included a significantly greater proportion of obese individuals (p = 0.013). Patients with PCOS exhibited elevated serum adipsin (p = 0.020) and reduced osteopontin (p < 0.001) levels relative to controls; obesity and age influenced these differences. Osteopontin demonstrated superior predictive power for PCOS diagnosis [area under the curve (AUC) = 0.802] compared with adipsin (AUC = 0.602). A combination of osteopontin and adipsin yielded the highest predictive value (AUC = 0.817) among double or triple biomarker combinations. Conclusions:This study identified potential associations among adipsin, osteopontin, irisin, and PCOS. Further research is warranted to elucidate their roles and clinical implications in PCOS and its metabolic alterations. The findings highlight the impact of age and obesity on these biomarkers and their relationships with PCOS, providing insight into the syndrome's complex pathophysiology.
