Publication Metadata only Cannabidiol as a potential novel treatment for endometriosis by its anti-inflammatory, antioxidative and antiangiogenic effects in an experimental rat model(2023-01-01) Okten S. B.; ÇETİN Ç.; Tok O. E.; Guler E. M.; Taha S. H.; ÖZCAN P.; Ficicioglu C.; ÇETİN, ÇAĞLAR; ÖZCAN, PINARResearch 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.Publication Metadata only Cardiometabolic profiles in women with adenomyosis(2022-07-01T00:00:00Z) ATEŞ, SEDA; Aydin, Serdar; ÖZCAN, PINAR; ATEŞ, SEDA; ÖZCAN, PINARThe 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 Statement What 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.Publication Metadata only Differences in clinical characteristics for the determination of adenomyosis coexisting with leiomyomas(2015-10-28T00:00:00Z) ATEŞ, SEDA; ÖZCAN, PINAR; AYDIN, SERDAR; KARACA, NİLAY; ATEŞ, SEDA; ÖZCAN, PINAR; AYDIN, SERDARPublication Open Access What Does the Data Show for Primary Ovarian Insufficiency?(2017-03-01T00:00:00Z) ÖZCAN, PINAR; Parasar, Parveen; Ficicioglu, Cem; ÖZCAN, PINARPrimary ovarian insufficiency (POI), a clinical syndrome, is defined by the exhaustion of the functional potential of ovaries prior to 40 years. The consequences of POI are potentially serious for long-term fertility, reproductive health, and general health because of early menopause. This article provides an updated review of different etiologic factors and pathogenic mechanisms that lie behind POI as well as current and novel strategies for the management of this challenging disease aimed at the primary prevention of the adverse effects of estrogen deficiency and infertility related to the early loss of ovarian function.Publication Metadata only The Effect of Serum Progesterone Level on ET Day and The Efficacy of Rescue Progesterone Treatment on Ongoing Pregnancy Rates with Artificial FET Cycle(2022-07-07T00:00:00Z) ÖZCAN, PINAR; ÇETİN, ÇAĞLAR; Ökten, B.; Tanoğlu, Fatma Başak; İŞLEK, HAVVA SEVDE; PASİN, ÖZGE; Fıçıcıoğlu, Cem; ÖZCAN, PINAR; İŞLEK, HAVVA SEVDE; PASİN, ÖZGEPublication Metadata only Age-Related Distribution of Basal Anti-Mullerian Hormone Levels in a Population of Infertile Women(2016-05-01) AYDIN, SERDAR; ÖZCAN, PINAR; AYDIN, SERDARAim: We aimed to constitute age-specific reference serum values for anti-Mullerian Hormone (AMH) in women, and to analyze the distribution of basal serum AMH levels in Turkish women of reproductive age attending an infertility clinic to provide a framework for expected values according to age. Material and Method: Retrospective analysis of prospectively collected data on cycle day 2-3 serum AMH measurements of 409 women attending a single infertility unit in Turkey through a 12-month-period was performed. Results: Concentrations of serum AMH were shown to decrease with advancing age of the female partner. The mean age of the women was 34.04 +/- 5.39 years and the mean AMH level of the women was 1.77 +/- 1.82. The AMH levels were grouped according to age as follows: 20-24, 25-29, 30-34,35-39, and >40 years. The median AMH values were 2.16 ng/ml, 2.15 ng/ml, 1.71 ng/ml, 0.80 ng/ml, and 0.47 ng/ml, respectively according to the age groups. Discussion: The present data provide a framework for age-specific serum AMH levels in a Turkish population of infertile women.Publication Metadata only The cutoff values of serum AMH levels and starting recFSH doses for the individualization of IVF treatment strategies(2017-01-01T00:00:00Z) ÖZCAN, Pınar; Ficicioglu, Cem; ATEŞ, SEDA; GÜNER CAN, Meltem; Kaspar, Cigdem; Akcin, Oya; Yesiladali, Mert; ÖZCAN, PINAR; ATEŞ, SEDAObjective: 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.Publication Metadata only Evaluation of chronotype and sleep quality in infertile population and comparison with fertile population: a cross-sectional study(2023-12-01) Özçelik C.; VARLI B.; Gökçe A.; Takmaz T.; ÇETİN Ç.; ÖZCAN P.; TAKMAZ, TAHA; ÇETİN, ÇAĞLAR; ÖZCAN, PINARPURPOSE: Infertility is a stressful condition for couples and can affect patients\" circadian rhythm and sleep quality. The goal of this study is to assess differences in chronotype and sleep quality between infertile and fertile people. METHODS: A cross-sectional study was conducted. The infertile patient population consisted study group. Primiparous patients without any known gynecological disease who presented for routine cervical cancer screening follow-up were included in the control group. The Turkish version of the Morningness-Eveningness Questionnaire (MEQ) and Pittsburg Sleep Quality Index (PSQI) scores were evaluated between groups. RESULTS: A total of 227 patients were assessed. There were 110 patients in the study (infertile) group and 117 patients in the control (fertile) group. The evening chronotype proportion (23.6 vs. 0.9%, p < 0.001) was higher in the infertile group. The median of MEQ score was significantly higher in the fertile patients (50, IQR = 43 - 55 vs. 56, IQR = 51 - 59; p < 0.001), and the median of PSQI score was significantly higher in the infertile patients (5, IQR = 4 - 6, vs. 4, IQR = 3 - 5; p < 0.001). CONCLUSIONS: In this study, we found significantly worse sleep quality, and more evening chronotype in the patients with infertility.Publication Metadata only Hysteroscopic findings in women with recurrent IVF failures and the effect of correction of hysteroscopic findings on subsequent pregnancy rates(2013-02-01T00:00:00Z) Cenksoy, PINAR; Ficicioglu, Cem; Yildirim, Gazi; Yesiladali, Mert; ÖZCAN, PINAROur aim is to evaluate the incidence of unrecognized uterine abnormalities in cases with recurrent IVF failure by screening office hysteroscopy (OH), and impacts of treatment of hysteroscopic findings on the success rate of IVF.Publication Metadata only Excision of subcutaneous endometriosis lesions in obese patients by marking them with methylene blue with ultrasound guidance: a novel technique(2023-01-01) ÇETİN Ç.; KÜTÜK M.
