RESUMO

The purpose of the study was to compare the ovarian stromal blood flow and stromal thickness (ST) of polycystic ovary syndrome (PCOS) patients, with healthy women with polycystic ovarian morphology (PCOM) and normal ovarian morphology (NOM). A total of 220 participants were recruited and the three study groups were determined by diagnostic criteria (PCOS n = 106, PCOM n = 68, NOM n = 46). Clinical, hormonal and ultrasonographic measurements of ovaries were assessed and compared. PCOS patients showed statistically higher androgen levels, insulin resistance, hirsutism score, ovarian ST and stromal blood flow compared to PCOM and NOM. The correlation between free androgen index (FAI) and ST was measured. FAI was significantly highly correlated with left ovarian ST (0.83; p < .001) and right ovarian ST (0.83; p < .001). According to the results of this study, the ovarian ST which can be considered as ultrasonographic indicator of FAI, can be used in PCOS diagnosis. Also, it can be suggested that there is no statistically significant difference in ovarian ST and doppler findings between healthy women with PCOM or NOM. ROC analysis was used to measure diagnostic utility of ST. Impact StatementWhat is already known on this subject? Although it is known that ovarian stromal blood flows and stromal thickness are increased in PCOS disease compared to healthy women, they are not included in the diagnostic criteria.What the results of this study add? In the results of this study, it was determined that ovarian stromal blood flow and stromal thickness were increased in PCOS patients, as previously reported in the literature. In addition, these ultrasound measurements were found to be increased in PCOS patients compared to healthy women with PCO morphology, and stromal thickness measurements were strongly correlated with the free androgen index in PCOS patients.What the implications are of these findings for clinical practice and/or further research? Ovarian ST and/or S/A ratio may be an ultrasonograpic indicator of FAI, and may be used in PCOS diagnostic criterias. In the future, it can be revealed whether they vary in patients with different components of the syndrome, by examining these parameters in different PCOS phenotypes.

RESUMO

OBJECTIVES: The aim of this study is to compare the annual SJR and to evaluate the other parameters that show the scientific effect of journals in terms of open access (OA) or subscription access (SA) in the field of obstetrics and gynecology according to the SCImago database. MATERIAL AND METHODS: This study was conducted between September-December 2019 at Near East University. The SCImago Journal & Country Rank database was used to collect information about the journals. We evaluated and compared the changes in the one-year SJR (SCImago Journal Rank) and journal impact factor (JIF) of OA and SA journals. RESULTS: Data from 183 scientific journals in the field of obstetrics and gynecology from the period between 1999 and 2018 were evaluated, where 140 of these journals were SA and 43 were OA. The average SJR of OA journals in 1999 was 0.17, while it was 0.38 for SA journals. In 2018, these values were 0.31 and 0.78 for OA and SA journals, respectively. In the comparison of JIF, the average of the OA journals in 1999 was 0.09, while it was 0.66 for SA journals. In 2018, these values were 0.80 and 1.93 for OA and SA journals, respectively. CONCLUSIONS: Access to information has become easier due to technological developments and this will continue to affect the access policies of journals. Despite the disadvantages of predator journals, the rise of OA journals in terms of number and quality is likely to continue.

RESUMO

OBJECTIVES: The aim is to compare the hormonal status and anti-müllerian hormone (AMH) levels of patients who have different polycystic ovary syndrome (PCOS) phenotypes, polycystic ovarian morphology (PCOM) and healthy women. MATERIAL AND METHODS: A total of 350 PCOS women, 71 women with PCOM and 79 healthy women with normal ovarian morphology (NOM) were observed. PCOS patients were divided into groups according to the phenotypes. Phenotype A- characterized by anovulation, hyperandrogenism and PCOM; phenotype B- defined as anovulation, hyperandrogenism; Phenotype C- identified as hyperandrogenism and PCOM; Phenotype D- outlined as anovulation and PCOM. AMH levels were compared for each group. RESULTS: Among 350 PCOS patients the highest number belonged to phenotype A (n = 117, 33.4%). The rest were distrubuted as follows: phenotype B (n = 89, 25.4%), phenotype C (n = 72, 20.6%), phenotype D (n = 72, 20.6%). Phenotype A (9.17 ± 4.56) had the highest mean AMH levels in our study. Comparison of AMH levels showed a statistically significant difference between phenotypes A and D. There was a statistically significant difference on comparison of AMH between NOM, PCOM and all PCOS phenotypes. CONCLUSIONS: Phenotype A is the most serious form of PCOS and these patients has all three features which are hyperandrogenism, anovulation and ultrasound findings of polycystic ovary (PCO). AMH reflects the severity of PCOS and patients with Phenotype A have higher AMH levels.

RESUMO

OBJECTIVES: The objective of the current research is to compare hormonal, metabolic and ovarian stromal blood flow outcomes in smoking versus non-smoking polycystic ovary syndrome (PCOS) patients. MATERIAL AND METHODS: 79 PCOS women (Group 1) and 79 healthy subjects (Group 2) were recruited. Both groups were subdivided according to their smoking habits. Ovarian stromal blood flow was assessed with pulsatility and resistance index for both ovaries and compared among smoking women. RESULTS: The smokers in the PCOS group had statistically significant higher levels of pulsatility and resistance index in both ovaries compared to nonsmoker PCOS patients (p < 0.001). Comparison of ovarian stromal blood flow indexes shows that pulsatility and resistance index for both ovaries is statistically significantly high in smoking healthy patients compared to the nonsmoking group (p < 0.001). There is a positive correlation between smoking and free androgen index (r = 0.866, p < 0.001) for PCOS patients and healthy women. CONCLUSIONS: Smoking reduces ovarian blood flow in PCOS patients and healthy subjects. Smoke components effect the vascular structure and form endothelial injuries that may reduce ovarian tissue perfusion. In this study, the positive correlation between smoking and free androgen index shows that the main effect of smoking on ovarian blood flow may be through androgen metabolism.

RESUMO

To evaluate whether 4 gram myoinositol and 400 mcg folic acid(MYO) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at 3 months follow-up period in polycystic ovary syndrome (PCOS). One-hundred eighty patients were designed into six groups; Group 1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3 mg drospirenone (DRP); Group 2: PCOS patients that received MYO; Group 3: PCOS patients that received no medication. Group 4: Healthy patients that received OCP; Group 5: Healthy patients that received MYO; Group 6: Healthy patients that received no medication. Resistance index (RI) and pulsatility index (PI) of both ovaries were assessed. There was a significant increase in RI and PI of both ovarian stromal blood flow women with PCOS who received OCP (Group 1, p < .001) and MYO (Group 2, p < .001). The rate of increment in both RI and PI values were similar for OCP users (Group 1) and MYO users(Group2) in PCOS patients. MYO therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months and this decrease is especially noticeable in women with PCOS compared to healthy women. OCP therapy also reduced ovarian vascularization just like MYO therapy.

RESUMO

Objective: The aim of the study is to investigate the effect of myo-inositol (MYO) on pregnancy rates of patients diagnosed with polycystic ovary syndrome (PCOS) who undergone controlled ovulation induction and intrauterine insemination (IUI). METHODS: A total of 196 infertile patients diagnosed with PCOS and admitted to Dokuz Eylul University Faculty of Medicine were included in the study between March 2013 and May 2016. The patients in group 1 (n = 98) were given 4 g MYO and 400 µg folic acid before and during ovulation induction. The patients undergone controlled ovarian hyperstimulation (COH) with recombinant FSH and IUI. The patients in group 2 (n = 98), were given recombinant FSH directly and 400 µg folic acid. The primary outcome measure of this study was the clinical pregnancy rate. RESULTS: In group 1, 9 patients conceived spontaneous pregnancy. During COH + IUI treatment three cycles were canceled in group 1 and 8 cycles in group 2. Total rFSH dose and cycle duration were significantly lower and clinical pregnancy rates were higher in group 1. The pregnancy rate for group 1 was %18.6 and for group 2 was %12.2. Conclusions: This study shows that MYO should be considered in the treatment of infertile PCOS patients. MYO administration increases clinical pregnancy rates, lowers total rFSH dose and the duration of the ovulation induction.

RESUMO

Recently, myoinositol (myo-ins) and folic acid combination has gained an important role for treating Polycystic Ovary Syndrome (PCOS), in addition to combined oral contraceptives (COC). We aimed to examine myo-ins effects on anti-Mullerian hormone (AMH) levels and compare them with those ones obtained administering COC. In this prospective study, 137 PCOS patients, diagnosed according to Rotterdam criteria and admitted to the Reproductive Endocrinology and Infertility Outpatient Clinic at Dokuz Eylul University (Izmir, Turkey), were included. After randomization to COC (n = 60) and myo-ins (n = 77) arms, anthropometric measurements, blood pressure, Modified Ferriman Gallwey scores were calculated. Biochemical and hormonal analysis were performed, and LH/FSH and Apo B/A1 ratios were calculated. Data analysis was carried out in demographically and clinically matched 106 patients (COC = 54; myo-ins = 52). After 3-month treatment, increase in HDL and decreases in LH and LH/FSH ratio were statistically more significant only in COC group when compared with baseline (in both cases p > 0.05). In myo-ins group, fasting glucose, LDL, DHEAS, total cholesterol, and prolactin levels decreased significantly (for all p < 0.05). Progesterone and AMH levels, ovarian volume, ovarian antral follicle, and total antral follicle counts lessened significantly in both groups (for all p < 0.05). In PCOS treatment, MYO is observed more effective in reductions of total ovarian volume and AMH levels.

RESUMO

OBJECTIVE: Due to the complex relationship between kisspeptin and the hypothalamic-pituitary-gonadal axis, the study was planned to measure the kisspeptin levels in polycystic ovary syndrome (PCOS) and to analyze the correlations between kisspeptin and PCOS-related reproductive, metabolic changes. METHODS: The study was designed as a prospective study in Dokuz Eylul University between December 2011 and September 2013. A total of 285 PCOS cases and 162 controls were recruited. After the antropometric measeruments and physcial examination, blood samples were taken for biochemical analysis. RESULTS: PCOS group's mean BMI was 24.32 ± 3.40 and for the control group, BMI value was 23.44 kg/m2 ± 4.08 (p = 0.351). PCOS patients' FSH level was 5.10 ± 2.01 mIU/L, LH value was 7.75 ± 4.31 mIU/mL, LH/FSH ratio was 1.70 ± 1.28, DHEAS value was 221.84 ± 105.02 mg/dl, total testosterone value was 50.51 ± 27.93 ng/ml, free testosterone value was 2.52 ± 1.05 pg/ml, SHBG was 63.74 ± 45.62 nmol/L, LDL was 102.56 ± 23.45 mg/dL, HDL value was 51.36 ± 12.15 mg/dL, total cholesterol value was 214.85 ± 39.27 mg/dL, triglyceride value was 112.95 ± 46.88 mg/dL, Apo A1 value was 171.30 ± 35.35 mg/dL, Apo B value was 71.08 ± 19.07 mg/dL, Apo B/A1 ratio was 0.42 ± 0.14, free androgen index was 13.77 ± 14.15, fasting glucose value was 80.68 ± 13.80 mg/dL, fasting insulin levels was 14.13 ± 9.11 µiU/mL, HOMA-IR index was 2.76 ± 2.34, AMH value was 5.93 ± 3:33 in ng/ml, and found to be significantly higher (p < 0.001). Leptin value was 9.71 ± 5.54 pg/ml and kisspeptin value was 1.92 ± 1.29 ng/ml, respectively. Kisspeptin and leptin levels showed no statistically significant difference with control group and PCOS group. In all PCOS patients, kisspeptin showed positive correlations between LH and leptin levels. CONCLUSION: In this study, kisspeptin had a positive correlation with LH and leptin levels in PCOS. In fact, the serum levels of kisspeptin and leptin does not differ statistically between PCOS and healthy women. There are limited data in the literature with regard to changes in kisspeptin levels and its relation with metabolic and hormonal disturbances.
