RESUMO
OBJECTIVE: To assess the impacts of Platelet-Rich Plasma(PRP) and Granulocyte Colony-Stimulating Factor(G-CSF) on a rat model with induced ovarian follicular damage caused by cyclophosphamide(Cy). MATERIALS AND METHODS: Forty-two Sprague-Dawley rats were randomly allocated into seven distinct groups as; Group 1(control): NaCl intraperitoneal (IP) injection was administered on days D1, D7, and D14. Group 2(Cy):Cy IP injection on D1 + NaCl IP injection on D7 and D14 were administered. Group 3(PRP): PRP IP injection on D1,D7 and D14 were administered. Group 4(Cy + PRP):Cy IP injection on D1 and PRP IP injection on D1, D7 and D14 were administered. Group 5(G-CSF): G-CSF IP injection on D1, D7 and D14 were administered. Group 6(Cy + G-CSF):Cy IP injection on D1+ G-CSF IP injection on D1, D7 and D14 were administered. Group 7(Cy + PRP + G-CSF):Cy IP injection on D1+ PRP IP injection on D1,D7 and D14+ G-CSF IP injection on D1,D7 and D14 were administered. Follicular number, histological scores of AMH and INSL3 stained follicles at different stages of follicular development, and serum Anti-Müllerian hormone(AMH) were evaluated. RESULTS: The primary, secondary, and antral follicle intensity scores for AMH-positive staining were most prominent in Groups 3 and 5. There was no significant difference between groups 4, 6 and 7 compared to group 1 in terms of follicule counts and AMH staining. The intensity scores of AMH-positive staining follicles were notably reduced in group 2 compared to groups 4, 6, and 7, with a significant difference (p < .01). Among the groups, group 2 exhibited the least intense antral follicle staining for INSL3, displaying a significant difference(p < .01) compared to the remaining groups. CONCLUSIONS: Autologous PRP and G-CSF might protect ovarian function in the face of ovarian damage caused by Cy-induced effects.

OBJECTIVE: Comparison of hormonal, metabolic and inflammatory markers of glutathione with metformin and Diane-35 in a rat model of PCOS induced by dehydroepiandrosterone. METHODS: Twenty-five female rats were randomized into four groups. Group 1 was administered a subcutaneous dose of 0.2 ml saline/day. Group 2 was given 0.2 ml of 1% carboxymethyl cellulose (CMC)/day orally for 28 days. A PCOS model was established with DHEA in rats. Group 3 was given 4.5 mg/kg/day of Diane-35 orally dissolved in 1% CMC for 28 days. Group 4 was given 300 mg/kg/day of metformin orally dissolved in 1 ml of saline for 28 days, and Group 5 was administered 100 mg/kg of glutathione intraperitoneally on days 35, 42, and 49. On day 56, the rats were sacrificed. Serum markers and follicle count were examined. RESULTS: Serum IL-6, hs-CRP, insulin, testosterone, SHBG, and MDA values were significantly lower in the glutathione group than in the PCOS group (p = 0.0006, p = 0.023, p = 0.0082, p = 0.0007, p = 0.0048, and p < 0.0001, respectively).The number of all follicles was similar between the control and glutathione groups (p < 0.05). When we compared the other groups with the PCOS group, the number of primary, secondary, atretic, and cystic follicles was significantly lower in the metformin and glutathione groups. The number of primordial and antral follicles was significantly higher than in the PCOS group. CONCLUSIONS: Glutathione plays anti-inflammatory and antioxidant roles, similar to metformin, by lowering serum IL-6, insulin, testosterone, CRP, and MDA levels; decreasing atretic/cystic follicle count; and improving antral follicle count and folliculogenesis in PCOS patients.

OBJECTIVES: We investigated the potential of glutathione to protect ovarian function in rats exposed to cyclophosphamide by measuring serum anti-Mullerian hormone (AMH) levels, follicle counts, and related parameters. DESIGN: Forty-two adult female Sprague-Dawley rats were randomly divided into six groups and treated with various combinations of cyclophosphamide, glutathione, and sodium chloride. On day 21, the rats were anesthetized, and their ovaries were removed for examination. PARTICIPANTS/MATERIALS, SETTING, METHODS: Histopathological examination, serum AMH concentrations, follicle counts, AMH-positive staining of follicle percentages were analyzed. Statistical analysis was performed using a one-way analysis of variance and Tukey's test, with significance set at p < 0.05. Secondary measures encompassed histopathological examination and percentages of AMH-positive staining of follicles. RESULTS: Significant differences were observed in follicle counts, AMH-positive follicle parameters, and serum AMH concentrations among the six groups. Group 2 (treated with cyclophosphamide) had the lowest primordial, primary, secondary, and antral follicle counts and the highest atretic count. Group 6, treated with cyclophosphamide and 200 mg/kg glutathione, showed improved follicle counts compared to those in group 2. Reducing the glutathione dose to 100 mg/kg was ineffective. LIMITATIONS: This was an experimental animal investigation with a comparatively modest sample size. Experimental studies should be conducted to determine the optimal dosage and duration of glutathione therapy. Information gathered from an experimental animal model may not yield precisely similar outcomes in humans; therefore, additional investigations are necessary to examine the impact of glutathione on women experiencing POI. CONCLUSIONS: The anti-oxidative protective effect of directly administered glutathione was demonstrated for the first time. Low-dose glutathione was ineffective, whereas a high dose yielded significant ovarian protection against cyclophosphamide. Our findings provide valuable insights for supplementing clinical trials on the protective effects of glutathione against ovarian damage.

INTRODUCTION AND HYPOTHESIS: The objective of this cross-sectional, epidemiological study was to characterize urinary tract and bowel symptom prevalence and the extent of discomfort/bother associated with them. Additionally, the authors aimed to explore factors associated with both conditions among Turkish female university students. Also, an insight into women's "communication regarding urinary incontinence and anal incontinence" with their family members was sought. METHODS: This is an internet-based national cross-sectional study. A study-specific 30-item questionnaire containing validated measures of symptom prevalence and bother (Urogenital Distress Inventory questionnaire short form and Colorectal-Anal Distress Inventory) were incorporated into the survey. Out of a total of 2,125 e-mail invitations that were sent, 1,226 responded with data included in this analysis. RESULTS: The age and BMI of all respondents were 26.53 ± 10.082, 23.45 ± 6.609 respectively. Nine hundred and eighty-five (80.5%) respondents claimed that they did not suffer a UI episode in the last year, whereas 10 people (0.08%) claimed that they had a urinary incontinence episode every day. Three hundred and fifty-seven responders (29.1%) stated that they suffered from "gas incontinence," 6 (0.5%) stool incontinence, and 20 (1.6%) declared that they had episodes of both stool and gas incontinence. Five hundred and forty-four participants (44%) reported that they had family relatives with a problem of "urinary incontinence" and 576 (47%) stated they had a conversation on "urinary incontinence." Seventy-five of the responders (6.1%) stated that they had a family member with "anal incontinence" and 246 (20.1%) responded that they had a conversation regarding "anal incontinence" with them. CONCLUSION: We have demonstrated that the prevalence of UI was 19.5%. Twenty-nine percent stated they suffered "gas incontinence," 0.5% stool incontinence, and 1.6% declared that they had episodes of both stool and gas incontinence.

OBJECTIVE: Our study's primary objective was to examine the effects of four different prophylactic protocols on the prevention of postpartum hemorrhage following vaginal birth, including carbetocin only, oxytocin only, and a combination of carbetocin or oxytocin with tranexamic acid. DESIGN: A multicentric randomized controlled trial. PARTICIPANTS/MATERIALS, SETTING, AND METHODS: This multicentric center prospective randomized controlled trial was conducted at the Department of Obstetrics and Gynecology of Bezmialem University and Van Health Teaching and Research Hospital from August 2022 to January 2023. The collected data included age, gravidity, parity, gestational age at birth, duration of delivery stages, prepartum hemoglobin and hematocrit concentrations, changes in hemoglobin and hematocrit concentrations, intrapartum blood loss, estimated blood loss after 2 h of vaginal delivery, Apgar scores at 1 and 5 min, birth weight, and neonatal intensive care unit (NICU) admission. Intrapartum blood loss was objectively measured in milliliters using a postpartum drape with a calibrated bag. The amount of bleeding was measured by subtracting the empty weight of the pads placed under the patient in the patient's bed within 2 h after delivery. Group I: carbetocin 100 µg/mL (n = 75), group II: oxytocin 5 IU/mL (n = 75), group III: carbetocin and tranexamic acid 50 mg/mL (n = 75), group IV: oxytocin and tranexamic acid (n = 75). RESULTS: The hemoglobin concentration decrease significantly differed between groups (1.03 ± 1.04, 1.3 ± 0.85, 1.4 ± 0.85, 1.41 ± 0.87, respectively; p < 0.001). Group 4 has the highest decrease in hemoglobin and hematocrit concentrations. When we investigated the subgroup differences, the decrease in hemoglobin concentration was significantly higher in group 2 than group 1 (1.30 ± 0.85 vs. 1.03 ± 1.04; p = 0.023), in group 2 than group 3 (1.3 ± 0.85 vs. 1.04 ± 0.9; p = 0.013), and in group 4 than group 3 (1.41 ± 0.87 vs. 1.04 ± 0.9; p < 0.001). The decrease in hematocrit level was significantly different between groups (3.07 ± 3.23, 3.55 ± 2.44, 2.13 ± 3.09, 4.25 ± 2.52; p < 0.001, respectively). No significant differences were observed in terms of mean blood loss between the four groups (277.19 ± 208.10, 294.13 ± 198.64, 274.33 ± 199.57, and 283.97 ± 178.11; p = 0.445, respectively). Furthermore, there was no significant difference between the groups in the rate of need for blood transfusion (1.3%, 5.4%, 4%, and 4%, respectively; p = 0.6). LIMITATIONS: The most important limitation of the study is a relatively small number of participants. CONCLUSION: In conclusion, our findings suggest that carbetocin may be more successful than oxytocin and oxytocin plus tranexamic acid regimens in terms of postpartum hemoglobin reduction, and there is no difference in terms of the need for blood transfusion when it is used for postpartum hemorrhage prophylaxis after vaginal delivery.

AIM: Our aim is to evaluate the level of knowledge, compliance with the screening program, and tendency to inform patients of the doctors working in FHCs where HPV testing is performed within the scope of the cervical cancer screening program in our country. METHODS: This cross-sectional study was performed between June and September 2022 with 113 family physicians working in different FHCs in different provinces in Turkey. Questionnaires prepared by the researchers were delivered to family physicians via online platforms. RESULTS: When the different age groups were evaluated, in two of the 24 knowledge-level questions (How many types of HPV are there? Can HPV infect men?) the rate of correct answers for participants under the age of 35 years was statistically significantly higher (p = 0.007; p = 0.032). With regard to professional experience, the group with fewer than 10 years of experience gave a statistically significant correct answer to two questions (How many types of HPV are there? Can HPV infect men?; p = 0.008; p = 0.037). It was observed that 107 (94.7%) of the 113 family physicians who participated in the survey recommended that their patients use condoms during intercourse, 110 (97.3%) recommended cervical cancer screening tests to patients who applied for another reason, 105 (92.9%) recommended the HPV vaccine to patients and their relatives and 60 (53.1%) recommended the HPV vaccine to patients who applied for another reason. CONCLUSIONS: The success of HPV vaccination programs is directly related to the beliefs of health personnel and their recommendations to the general population.

Introduction: Due to the superficial peritoneal spread of ovarian cancer, upper abdominal surgical procedures are often required to achieve optimal surgical cytoreduction. This study compares the mortality and morbidity rates of patients undergoing upper and lower abdominal cytoreductive surgery in our institution. Material and Methods: Patients who underwent cytoreductive surgery for ovarian malignancies from 2014 to 2020 were retrospectively identified from an institutional database. Upper abdominal cytoreduction was defined anatomically as debulking of disease proximal to the ligament of Treitz. Perioperative and postoperative outcomes were analyzed. Results: A total of 148 operations were performed. A single gynecologic oncologist performed all procedures. When all cytoreductive procedures were evaluated, diaphragm injury, blood transfusion, hospital stay, atelectasis, pneumonia, effusion, wound infection and need for intensive care were found to be statistically significantly higher in patients who underwent upper abdominal surgery compared to patients in the lower abdominal surgery group (p=0.001, p=0.017, p=0.002, p=0.045, p=0.006, p=0.005, respectively). Conclusion: In patients scheduled for cytoreductive surgery with the diagnosis of ovarian cancer, upper abdominal surgery is a viable procedure, although it carries a higher risk of complications compared to lower abdominal surgery alone. Upper abdominal surgery in advanced ovarian cancer can be applied to patients with an acceptable complication profile when the possible survival advantage is considered.

RESEARCH QUESTION: What is the efficacy and possible positive effect of additional rescue subcutaneous (s.c.) progesterone therapy for restoration of progesterone concentration on embryo transfer day and pregnancy rates during programmed artificial frozen embryo transfer (FET) cycles with vaginal progesterone tablet plus i.m. progesterone? DESIGN: Multicentre prospective cohort study (NCT04769401) including a total of 238 programmed artificial FET between February 2021 and September 2021. Patients were divided into ≥10 ng/ml and <10 ng/ml according to serum progesterone concentrations on embryo transfer day; 25 mg of s.c. progesterone was added to patients with <10 ng/ml; blood samples were taken 2 days later. The primary outcome was the ongoing pregnancy rate. RESULTS: The proportion of patients having ≥10 ng/ml serum progesterone concentrations on embryo transfer day was 70.7%. There was no statistically significant difference with regard to cumulative pregnancy rate, ongoing pregnancy rate and miscarriage between the groups (55.4% versus 61.5%, P = 0.4; 78.2% versus 72.5% per pregnancy, P = 0.5; 21.8% versus 27.5%, P = 0.5, respectively, ≥10 ng/ml and <10 ng/ml). Eighty-three per cent of patients with low serum progesterone concentrations on embryo transfer day reached an adequate progesterone concentration with rescue s.c. progesterone treatment; 90% of pregnancy rates in patients with serum progesterone concentrations <10 ng/ml on embryo transfer day were in patients who reached adequate serum progesterone concentrations with daily rescue s.c. progesterone treatment. CONCLUSIONS: The measurement of serum progesterone concentrations on embryo transfer day may create the opportunity for rescue progesterone administration on that day for patients who fail to reach adequate serum progesterone concentrations, achieving similar pregnancy rates without cancellation of the cycle.

INTRODUCTION AND HYPOTHESIS: We present a video describing the technical considerations for performing a total colpocleisis in the management of significant, neglected, ulcerated, and symptomatic complete uterovaginal prolapse. METHODS: A 79-year-old debilitated woman presented with a large, ulcerated pelvic bulge. A previous attempt at pessary treatment failed because of a disproportion of the pessary with the prolapse size. She had a history of liver insufficiency and hypertension. Obliterative colpocleisis surgery was selected because the healing of a large ulcerated vagina was not likely within a short timeframe. Sharp dissection with scissors and de-epithelialisation of the remaining non-eroded vaginal mucosa with the friction of a sharp-edged surgical knife were performed. Closely located purse strings were used to obliterate potential spaces. Two mirror image triangles in the anterior and posterior vaginal walls were removed. After the formation of a new perineal body, the diamond-shaped vaginal incision was closed vertically to narrow introitus. RESULTS: The patient was discharged on the first postoperative day and an uncomplicated postoperative course ensued. At the 4-week follow-up, there was no evidence of infection, recurrent prolapse, de novo stress incontinence, or voiding with difficulty. CONCLUSIONS: Total colpocleisis is an excellent surgical option in women with multiple, large cervicovaginal ulcers and multiple comorbidities with no desire for penetrative vaginal function.

The study aimed to investigate the effects of cystocele and rectocele on the stages of vaginal birth and maternal and newborn outcomes. A total of 672 multiparous pregnant women between the ages of 18 to 40 who underwent normal vaginal delivery in our tertiary center between November 2022 and February 2023, were included in this prospective study. Among the participants, 348 (51.8%) had no abnormalities, 78 (11.6%) had rectocele only, 112 (16.7%) had cystocele only, and 134 (19.9) had both cystocele and rectocele. Patients with the coexistence of cystocele and rectocele experienced a notably extended duration for both the first stage and second stage of labor, although the extension in the second stage was not statistically significant. Among the maternal complications, the development of maternal laceration and chorioamnionitis was significantly more common in the patient group with cystocele and rectocele compared to the other groups. When the groups were assessed for postpartum bleeding, while the bleeding risk increased from the normal group to the rectoceleâ +â cystocele group, this increase was not statistically significant. There was no difference between the groups in terms of neonatal outcomes. The delivery time of pregnant women with cystocele and rectocele, in the absence of additional risk factors, was determined to be significantly longer than that of the control group. We think that these patients should receive more vigilant monitoring, and this criterion should be kept in mind when assessing the indication for a cesarean section.

OBJECTIVES: To compare the efficacy of three regimes of uterotonic agents on PPH in women undergoing cesarean section in our RCT. MATERIAL AND METHODS: This study was a randomized controlled study (NCT05083910) performed at the Bezmialem Vakif University between July 2021 and January 2022. All women were randomly allocated into three groups: Group I (n = 52) - oxytocin only; Group II (n = 52) - the combination of oxytocin plus intrauterine misoprostol; Group III (n = 52) - carbetocin only. The primary outcome measures were: PPH to evaluate with the change between the concentrations of preoperative and postoperative hemoglobin, hematocrit and intraoperative blood loss. RESULTS: The blood loss characteristics, including the change in hemoglobin and the change in hematocrit concentration, intraoperative blood loss, intraoperative additional hemostatic uterine sutures and the need for additional uterotonics, were lowest in group III, although all groups were comparable in terms of blood loss parameters. Group III had the highest blood loss ratio, exceeding 1000 mL. For the combination of oxytocin and intrauterine misoprostol, the ARR was 3.8% (95% CI 20.02-12.33), with a RR of 1.18 (95% CI 0.58-2.39) and a NNT of 26 (95% CI 8.1-4.9); for carbetocin, the ARR was 5.8% (95% CI 22.15-10.61), with a RR of 1.27 (95% CI 0.63-2.53) and a NNT of 17 (95% CI 9.41-4.51). CONCLUSIONS: Our results demonstrate that carbetocin shows no superiority in the prevention of PPH in women undergoing cesarean section. Oxytocin still seems to be a highly effective alternative to prevent PPH.
