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.

RESUMO

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.

RESUMO

OBJECTIVE: The aim of this study was to investigate if adipose-derived stromal vascular fraction (SVF) treatment has any protective effect on ovarian function in rats with cyclophosphamide (CP) induced ovarian damage. DESIGN: This was an experimental animal study. PARTICIPANTS/MATERIALS, SETTING, METHODS: 25 mature cycling Wistar-Albino rats were randomized into four groups (n = 5 per group). Rats in groups 1 and 2 received single dose of intraperitoneal (i.p.) 1 mL/kg sodium chloride 0.9% (NaCl). Groups 3 and 4 received single dose of 75 mg/kg i.p. CP. On seventh day, SVF was prepared from adipose tissues of 5 additional rats and groups 1 and 3 received 0.9% NaCl i.p. injections while groups 2 and 4 received 0.2 mL i.p. injections of SVF. On day 21 all rats were euthanized, and serum anti-mullerian hormone (AMH) levels, primordial, primary, secondary, antral, and atretic follicle counts, AMH positive staining follicle counts along with AMH staining intensity of the follicles were evaluated. RESULTS: Among two CP induced ovarian damaged groups, SVF treated group showed significantly higher secondary and antral follicle and lower atretic follicle counts, significantly higher mean serum AMH levels, AMH positive antral follicle count and higher intensity of AMH positive follicle scores for primary, secondary, and antral follicles when compared to untreated group. Moreover, group 1 showed no significant difference for all parameters except antral follicle count and AMH positive staining intensity scores for antral follicles when compared to group 4. LIMITATIONS: This study was conducted on experimental rat model. CONCLUSION: Our study demonstrated a significant protective effect of SVF against CP-induced ovarian damage which reveals the apparent need for further investigation of its precise mechanisms of action as it may provide a new treatment approach for women with premature ovarian failure.

RESUMO

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.

RESUMO

RESEARCH QUESTION: Can cannabidiol (CBD) be used in the treatment of endometriosis for its anti-inflammatory, antioxidative and antiangiogenic effects? DESIGN: Endometrial implants were surgically induced in 36 female Wistar albino rats. After confirmation of endometriotic foci, the rats were randomized into four groups. In the leuprolide acetate group, rats were given a single 1 mg/kg s.c. leuprolide acetate injection. The other groups were 5 mg/kg CBD (CBD5), saline solution and 20 mg/kg CBD (CBD20); daily i.p. injections were administered for 7 days. After 21 days, the rats were euthanised, and total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α) measurements in blood and peritoneal fluid samples, and immunohistochemical staining for TNF-α, IL-6 and vascular endothelial growth factor (VEGF) of endometriotic tissues were evaluated. RESULTS: Significant reductions in the endometriotic implant surface area (P = 0.0213), serum TOS (P = 0.0491), OSI (P = 0.0056), IL-6 (P = 0.0236), TNF-α (P = 0.0083) and peritoneal fluid OSI (P = 0.0401), IL-6 (P = 0.0205) and TNF-α (P = 0.0045) concentrations were observed in the CBD5 group when compared with the saline solution group. Compared with the saline solution group, increased TAS concentrations in serum (P = 0.0012) and peritoneal fluid (P = 0.0145) were found in the CBD5 group. The CBD5 and leuprolide acetate groups were similar regarding inflammatory and oxidative stress parameters of serum and peritoneal fluid samples. The CBD5 group showed significantly lower mean intensity in both surface epithelium and stromal cells for VEGF (both P = 0.002) and only in surface epithelium cells for IL-6 (P = 0.0108), when compared with the leuprolide acetate group. CONCLUSION: Due to its anti-inflammatory, antioxidative and antiangiogenic effects, CBD might be a therapeutic agent candidate for endometriosis.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: Endometriosis affects the quality of life, sleep, and sexual life of patients due to pain. This study compared the scores of endometriosis patients in these three areas before and after surgery. METHODS: Patients between the ages of 18 and 60 with a prediagnosis of endometriosis were enrolled. Postoperative histopathological diagnosis of endometriosis was confirmed in all patients. This study included 56 patients who completed pre- and postoperative (three months) evaluation of quality scale questionnaires: a visual analog scale for pelvic pain, the Pittsburgh Sleep Quality Index, Morningness-Eveningness Questionnaire, Endometriosis Health Profile-30 Questionnaire, and Female Sexual Function Index were administered prior to and 3 months after each patient's surgery. RESULTS: Among the 56 female patients included in this study, statistically significant improvement was observed in pain scores, quality of life, sexual function, and sleep of all patients regardless of endometriosis stage. CONCLUSION: Endometriosis is a disease that progresses, with increasing pain scores; it has negative effects on the quality of life, sexual function, and sleep of patients. Surgical or medical treatment can be performed considering the complaints and fertility status of the patients.

RESUMO

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.

RESUMO

The aim of this study was to investigate the reproductive profiles, metabolic parameters and cardiometabolic risk assessed by surrogate indexes in women with adenomyosis. Ninety-six premenopausal women who were diagnosed with adenomyosis by transvaginal ultrasound and 97 age-body mass index (BMI) matched controls with normal ultrasound during routine examination were included. Women with adenomyosis were more likely to have higher gravidity and had more abortions than women without adenomyosis. Regarding the individual metabolic syndrome components, the adenomyosis group was more likely to have higher prevalence of hypertension, low HDL-C and central obesity. No significant difference was found between the groups in terms of visceral adiposity index, lipid accumulation product and fatty liver index. Only higher blood pressure (BP) remained statistically significant after adjustment for confounding factors in multivariate analysis. Women with adenomyosis had remarkably high risk of hypertension. It may be advisable to monitor their BP closely.Impact StatementWhat is already known on this subject? The only anthropometric characteristic assessed in women in relation to adenomyosis is body mass index (BMI). A case-control study showed that women who are obese are more likely to have adenomyosis. The gravidity, number of spontaneous abortions and previous uterine surgeries such as dilatation and curettage (D&C) and caesarean section were found significantly associated with adenomyosis.What do the results of this study add? A remarkable finding of our study was the increased incidence of higher systolic BP in women with adenomyosis. No difference was observed in adiposity indices between women with and without adenomyosis. Higher prevalence of central obesity and lower HDL-C levels were seen in women with adenomyosis.What are the implications of these findings for clinical practice and/or further research? The study identifies that adenomyosis is associated with an increased risk of hypertension, and women with adenomyosis may be monitored closely for blood pressure changes. Our report also provides novel information about the metabolic risk profiles associated with adenomyosis.

RESUMO

AIM: To identify which positive prognostic parameters contribute to successful treatment outcomes and the probability of pregnancy by analyzing the results of infertile couples underwent ovulation stimulation (OS) and intra-uterine insemination (IUI) in our clinic. METHODS: Five hundred and nineteen couples who underwent OS-IUI treatment because of a mild-moderate male factor, unexplained infertility, or anovulation were retrospectively analyzed. The data collected included patient demographics, cycle characteristic, sperm parameters and pregnancy rates. The main outcome measure was pregnancy rate (PR). RESULTS: Our overall PR was 17.72% (n = 92). In women who did not achieve pregnancy, age, BMI and duration of infertility were significantly higher (P < 0.001, P < 0.001 and P = 0.03, respectively). The IUI indications of higher PR were unexplained infertility (P = 0.018) and primary infertility (P = 0.003). AFC was significantly lower and the total dosage of gonadotropins was significantly higher in women who did not achieve pregnancy (P = 0.001 and P = 0.017, respectively). The number of progressive motile spermatozoa inseminated and the morphology were significantly higher in women who did not achieve pregnancy (P = 0.056 and P = 0.001, respectively). Female age ≤ 30 (OR = 0.87; 95% CI: 0.81-0.95; P < 0.01), BMI ≤23.3 kg/m2 (OR = 0.87; 95% CI: 0.80-0.95; P = 0.002) and AFC > 9 (OR = 1.07; 95% CI: 1-1.15; P = 0.034) increase the pregnancy. CONCLUSION: Younger women, especially those with unexplained infertility, primary infertility, shorter duration of infertility, normal ovarian reserve, higher motile spermatozoa inseminated and sperm morphology, could benefit from OS-IUI.

RESUMO

AIM: To evaluate the clinical outcome of assisted reproductive technology (ART) cycles in couple with male infertility, where the spermatozoa were selected using either a conventional gradient-density centrifugation technique or microfluidic sperm sorting. METHODS: A total of 181 patients who underwent in vitro fertilization (IVF) because of male factor infertility at the IVF center of Bezmialem and Yeditepe University Hospital were included in this study. All patients were divided into two groups according to the sperm selection method: group I (n = 91): microfluidic sperm-sorting chip; group II (n = 90): density-gradient centrifugation. Data collected included male and female age, type of infertility, duration of infertility, previous IVF attempts, smoking, antral follicle count, total dosage of gonadotropins, maximum estradiol levels, duration of stimulations, endometrial thickness on human chorionic gonadotropin day, total number of oocytes retrieved, number of mature oocytes retrieved, number of pronuclear (PN), sperm parameters, clinical PR and ongoing PR. RESULTS: There was no statistically significant difference in clinical PR and ongoing PR between groups (49.5% vs 40%, P = 0.2; 44% vs 36.7%, P = 0.3; respectively). The improvement in pregnancy rate was more prominent in patients where the female partner's age is higher than 35 (P = 0.09) and men have a total motile sperm count between 1 and 5 million (P < 0.01). CONCLUSION: Microfluidic devices, "labs-on-a-chip," are a disposable, easy to use, and inexpensive method for sperm sorting. Our results show that IVF success rates might improve with the use of a microfluidic sperm-sorting chip for sperm selection in male infertility.

RESUMO

In this prospective study, seventy-six patients (PCOS group; n = 36, multifollicular ovary group; n = 40) were evaluated by 2-D and 3-D ultrasonography. VOCAL programme, echogenicity, number of follicles and blood flow parameters were evaluated. The patients with PCOS had a higher total ovarian volume, mean stromal volume and stromal echogenicity (18.6 ± 4.75 to 10.2 ± 3.4 p < .01; 12.23 ± 2.53 to 5.02 ± 2.44 p = .02; score 1:28 to 10 p < .01, respectively). There was no statistically significant difference in terms of mean RI and PI values between the groups (p > .05). 3 D power Doppler parameters included VI, FI, and VFI values of the patients with PCOS were higher when compared to those of the patients with multifollicular ovary (3.82 ± 2.65 to 1.78 ± 1.2, p < .01; 50.76 ± 4.45 to 40.6 ± 3.64, p = .03; and 2.34 ± 1.02 to 1.12 ± 0.65, p = .02, respectively). Our results revealed that total ovarian volume, stromal volume and echogenicity; VFI, VI, and FI could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.Impact statementWhat is already known on this subject? Ultrasonography is considered the new diagnostic tool for PCOS. Enlarged ovaries with multiple small follicles peripherally located around increased ovarian stroma with increased stromal echogenicity are the sonographic features of polycystic ovaries.What do the results of this study add? 3-D Doppler ultrasonography may be more specific in the determination of multifollicular and polycystic ovaries when compared to RI and PI in 2-D Doppler ultrasonography. Moreover, 3-D power Doppler ultrasonography could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.What are the implications of these findings for clinical practice and/or further research? In clinical practice, the differentiation of multifollicular ovaries and polycystic ovaries (PCO) is difficult with the use of 2-D sonography alone. Therefore, 3-D ultrasound and power Doppler may also be used in addition to 2-D ultrasound for the differentiation of multifollicular ovaries and PCO.

RESUMO

PURPOSE: This study aimed to compare the effects of two different suture materials, monofilament synthetic absorbable sutures versus multifilament synthetic absorbable sutures, on healing the uterine scar after a cesarean delivery. METHODS: A total of 95 women between the ages of 18 and 40 who had undergone a primary cesarean section (CS) after the 38th week of gestation. In Group I (n=48), continuous double-layer unlocked closure of the low transverse uterine incision was performed using monofilament synthetic absorbable sutures. In Group II (n=47), continuous double-layer unlocked closure of the low transverse uterine incision was performed using multifilament synthetic absorbable sutures. Six months after the operation, the integrity of the cesarean scar at the uterine incision site was assessed using hydrosonography. The healing ratio and the thickness of the residual myometrium covering the defect were calculated as markers of uterine scar healing. RESULTS: No statistically significant differences were observed between the groups with regard to the preoperative hemoglobin concentrations, the change in the hemoglobin concentrations, operating time, and the number of intraoperative additional hemostatic uterine sutures. Mean thickness of the residual myometrium covering the defect was thicker in the monofilament suture group in comparison to the multifilament suture group (7.76±2.11 vs. 5.96±1.69, respectively; p<0.01). The mean healing ratio was significantly higher in the monofilament suture group in comparison to the multifilament suture group (0.76±0.13 vs. 0.60±0.12, respectively; p<0.01) CONCLUSION: Continuous double-layer unlocked closure of the uterine incision at cesarean delivery using monofilament synthetic absorbable sutures decreases the risk of CS scar defect.

RESUMO

PURPOSE: We evaluated the protective effect of PRP on ovarian function in female rats with cyclophosphamide (Cy)-induced ovarian damage. METHODS: Thirty-two adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose ip injection), group 2 (Cy); 75 mg/kg, single-dose ip injection and sodium chloride 0.9% (1 mL/kg, single-dose ip injection), group 3 Cy plus PRP, Cy (75 mg/kg, single-dose and PRP (200 µl, single-dose) ip injection), group 4 (PRP, 200 µl, single-dose ip injection). Primordial, antral, and atretic follicle counts; serum anti-Müllerian hormone (AMH) levels; AMH-positive granulosa cells; and gene expression analysis of Ddx4 were assessed. RESULTS: Serum AMH levels were significantly lower in group 2 compared to groups 1, 3, and 4 (p < 0.01, p < 0.01, and p = 0.04, respectively). A significant difference was found in the primordial, primary, secondary, antral, and atretic follicle counts between all groups (p < 0.01). There was a statistically significant difference in AMH-positive staining primary, secondary, and antral follicles count between the groups (p < 0.01). There was a statistically significant difference in primary, secondary, and antral AMH positive staining follicle intensity score between the groups (p < 0.01). Ddx4 expression in group 4 was highest compared to other groups. CONCLUSION: Our study may provide evidence that PRP could protect ovarian function against ovarian damage induced by Cy. It could lead to improved primordial, primary, secondary, and antral follicle numbers.

RESUMO

PURPOSE: The aim of our study was to evaluate the positive effect of starting an IV oxytocin infusion early before uterine incision on intraoperative blood loss. METHODS: A total of 101 women between 18-40 years who underwent a primary elective cesarean section (CS) were included in this randomized controlled trial. The patients were divided into two groups. In Group I (n=51), oxytocin infusion was administered immediately after incision of the visceral peritoneum during CS. In Group II (n=50), infusion was administered immediately after clamping the umbilical cord. The primary outcome was the mean volume of blood loss during CS. The secondary outcomes included the mean reduction in hemoglobin and hematocrit levels, need for additional uterotonics and hemostatic uterine sutures, blood transfusion, post-operative pain score, and additional surgical procedures. RESULTS: There were statistical significant differences either in the change of the hemoglobin concentration (1.27±0.75 vs.1.74±0.81; p<0.01) or in the change of hematocrit concentration (3.89±2.24 vs. 5.41±2.93; p<0.01). Intraoperative blood loss was significantly lower in Group I when compared to Group II (475.86±150.11 vs. 605.1±203.2; p<0.01). CONCLUSIONS: Our findings suggest that the starting IV oxytocin infusion early before uterine incision reduces intraoperative blood loss. This could be effective to replace starting IV oxytocin infusion late after umbilical cord clamping or delivery of the placenta. EINLEITUNG: Das Ziel unserer Studie war es. die positive Wirkung der beginnenden IV Oxytocin-Infusion früh vor der Uterusinzision auf den intraoperativen Blutverlust zu bewerten. MATERIAL UND METHODIK: In diese randomisierte kontrollierte Studie wurden insgesamt 101 Frauen zwischen 18 und 40 Jahren eingeschlossen, die sich einem primären elektiven Kaiserschnitt unterzogen hatten. Die Patienten wurden in 2 Gruppen eingeteilt. Gruppe I (n=51); Die Oxytocin-Infusion wurde unmittelbar nach der Inzision des viszeralen Peritoneums während der CS verabreicht. Gruppe II (n=50); Die Infusion wurde unmittelbar nach dem Klemmen der Nabelschnur verabreicht. Das primäre Ergebnis war das mittlere Blutverlustvolumen während der CS. Zu den sekundären Ergebnissen gehörte die mittlere Verringerung der Hämoglobin- und Hämatokritwerte, Bedarf an zusätzlichen Uterotonika und hämostatischen Uterusnähten, Bluttransfusion, postoperativer Schmerzscore und zusätzliche chirurgische Eingriffe. ERGEBNISSE: Es gab statistisch signifikante Unterschiede zwischen der Änderung der Hämoglobinkonzentration 1,27±0,75 vs.1,74±0,81; p<0,01) oder der Änderung der Hämatokritkonzentration(3,89±2,24 vs. 5,41±2,93; p<0,01). Der intraoperative Blutverlust war in Gruppe I im Vergleich zu Gruppe II signifikant geringer (475,86±150,11 vs. 605,1±203,2; p<0,01). DISKUSSION: Unsere Ergebnisse legen nahe, dass die beginnende intravenöse Oxytocin-Infusion früh vor der Uterusinzision den intraoperativen Blutverlust verringert. Dies könnte wirksam sein, um eine beginnende intravenöse Oxytocin-Infusion zu einem späten Zeitpunkt nach dem Klemmen der Nabelschnur oder der Abgabe der Plazenta zu ersetzen.

RESUMO

The aim of this study was to investigate the clinical, endocrine, metabolic features and prevalence of metabolic syndrome (MBS) in Turkish adolescents with polycystic ovary syndrome (PCOS) and the differences in metabolic parameters between adolescent PCOS with or without the presence of polycystic ovaries (PCO) on ultrasound. Subjects (n = 77) were classified into two groups: oligomenorrhea (O) and clinical and/or biochemical hyperandrogenism (HA) (n = 38), without PCO and O + HA with PCO (n = 39). The control group consisted of 33 age-matched adolescents. Adolescents with PCOS had a significantly higher body mass index (BMI), waist circumference and levels of LH, LH/FSH ratio, triglyceride, insulin, HOMA-IR, free androgen index and lower levels of SHBG and FSH. After adjustment for BMI, LH, LH: FSH ratio remained significantly higher. Adolescents with PCOS had a higher prevalence of MBS. No significant differences in lipid profiles, insulin levels and insulin sensitivity in both the PCOS groups were seen. HDL-C levels were lower in the O + HA + PCO group compared to the controls. BMI may be the major contributing factor in the development of metabolic abnormalities in adolescents with PCOS. Impact statement Many studies have investigated the effect of PCOS on metabolic and cardiovascular risks. It is thought that PCOS increases metabolic and cardiovascular risks. Increase in metabolic and cardiovascular risks associated with PCOS may be handled with early diagnosis and early intervention of PCOS in adolescents, although the diagnosis of PCOS in adolescents could be hard because of the features of PCOS overlapping normal pubertal physiological events. However, early identification of adolescent girls with PCOS may provide opportunities for prevention of well-known health risks associated with this syndrome and reduction of long-term health consequences of PCOS by reducing androgen levels and improving metabolic profile. Our results also support that BMI may be the major contributing factor in the development of metabolic abnormalities in adolescents with PCOS.

RESUMO

OBJECTIVE: The main purpose of our study is to categorize starting doses of recombinant follicle-stimulating hormone (recFSH) based on various cutoff values of anti-Mullerian hormone (AMH) and to determine the effectiveness of serum AMH levels in the prediction of poor ovarian response. MATERIAL AND METHODS: Prospective data analysis was conducted at IVF center. A total of 323 patients were included. All patients were divided into four groups according to the patients' serum AMH concentrations: Group 1 (AMH < 1 ng/ml; 450 IU/day n = 157); Group 2 (AMH 1-2 ng/ml; 375 IU/day, n = 55); Group 3 (AMH 2-3 ng/ml; 225 IU/day, n = 48); and Group 4 (AMH > 3 ng/ml; 150 IU/day, n = 63). Collected data included age, total gonadotropin dosage, duration of stimulations, the total number of oocytes retrieved, ovarian response, cancelation rate, and cPRs. RESULTS: As serum AMH levels increased, there were significant decreases in the starting recFSH dose and total gonadotropin dosage, and a significant increase in the total number of oocytes retrieved. There was a significant trend toward increasing cycle cancelation rates and decreasing cPRs with decreasing serum AMH levels. Although there were no significant differences with regard to the proportion of cycles with hypo-response between all groups. A result of ≤0.83 was considered the cutoff value of AMH to predict a hypo-response to ovarian stimulation. CONCLUSIONS: AMH is a useful marker in selecting the starting dose of recFSH and prediction of poor ovarian response. Our protocol may allow clinicians to modulate the starting dose of recFSH according to these cutoff values for serum AMH levels.

RESUMO

AIM: The objective of the analysis was to determine the characteristics that distinguish women with adenomyosis and leiomyomas from those with leiomyoma only from a sample who underwent hysterectomy for benign uterine diseases. METHODS: This retrospective study was based on the analysis of medical records of 75 women with both adenomyosis and uterine leiomyomas and 218 women with leiomyomas only, diagnosed by histologic analysis of uterine specimens. RESULTS: Results of multivariate logistic regression analyses showed that women with both adenomyosis and leiomyomas had a higher gravity (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.01-1.33) and more frequent pelvic pain (OR 0.38, 95% CI 0.21-0.7) compared with women with leiomyomas only. Postmenopausal bleeding was commonly reported in women with adenomyosis and leiomyomas. No significant difference was observed between the two groups in terms of menorrhagia and metrorrhagia and the preoperative diagnosis of prolapse. CONCLUSIONS: The presence of concomitant adenomyosis may cause different clinical symptomatology.
