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 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 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. S.; Tanoğlu F. B.; ATEŞ S.; ÖZCAN P.; BAKAR R. Z.; ÇETİN, ÇAĞLAR; KÜTÜK, MEHMET SERDAR; TANOĞLU, FATMA BAŞAK; ATEŞ, SEDA; ÖZCAN, PINAR; BAKAR, RABIA ZEHRAPublication Open Access Vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC): technique and mean 20 months outcomes(2020-12-01T00:00:00Z) ŞEVKET, OSMAN; TAKMAZ, TAHA; Sevket, A. C.; TOPRAK, ALİ; ÖZCAN, PINAR; ŞEVKET, OSMAN; TAKMAZ, TAHA; TOPRAK, ALİ; ÖZCAN, PINARThe main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse. We retrospectively reviewed the results of twenty-three women with stage III and IV prolapse treated with VALSAC between April 2017 and June 2019. With a mean follow-up of 20 months, apical pelvic organ prolapse was cured in 95.7 % of patients. There was no complication in terms of mesh exposure, persistent pain, hematoma, infection. The mean pre- and post-operative POP-Q scores were, for the Aa point, 1.61 +/- 1.82 cm and -1.96 +/- 0.87 cm (p < 0.01), for the C point, 2.87 +/- 1.6 cm and -5.26 +/- 1.86 cm (p < 0.01) for the Ap point, -1.43 +/- 0.89 cm and -2.09 +/- 0.59 cm (p < 0.01). VALSAC is a promising minimally invasive technique for pelvic floor reconstruction that appears to provide good outcomes. Content: The main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse.Publication Open Access The protective effect of platelet-rich plasma administrated on ovarian function in female rats with Cy-induced ovarian damage(2020-04-01T00:00:00Z) ÖZCAN, Pınar; TAKMAZ, TAHA; Tok, Olgu Enis; Islek, Sevde; Yigit, Esra Nur; Ficicioglu, Cem; ÖZCAN, PINAR; TAKMAZ, TAHAPurpose 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 mu l, single-dose) ip injection), group 4 (PRP, 200 mu l, single-dose ip injection). Primordial, antral, and atretic follicle counts; serum anti-Mullerian 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.Publication Open Access Vitamin D status in the first-trimester: effects of Vitamin D deficiency on pregnancy outcomes(2016-01-01) Ates, SEDA; Sevket, OSMAN; ÖZCAN, PINAR; ÖZKAL, Fulya; Kaya, MEHMET ONUR; Dane, Banu; ATEŞ, SEDA; ŞEVKET, OSMAN; ÖZCAN, PINAR; KAYA, MEHMET ONUR; KILIÇOĞLU DANE, PAKİZER BANUObjective: To assess serum levels of 25-hydroxyvitamin D [25(OH)D] in the first trimester and to determine the factors affecting deficiency levels and its association with pregnancy outcomes. Methods: Serum 25(OH)D concentrations were measured at 11-14 weeks' gestation in 229 singleton pregnancies using liquid chromatography-tandem mass spectrometry. Results: The median serum 25(OH)D concentration was 10.8 ng/mL and 45.9% of women had severe vitamin D deficiency with concentrations of <10 ng/mL. Logistic regression analysis revealed that covered dressing style, lack of multivitamin intake, season of blood sampling (November-April) were factors associated with 25(OH)D deficiency. There was a negative correlation between 25(OH)D levels and gestational age at sampling. Low 25(OH)D levels were not associated with adverse pregnancy outcomes. Higher rate of cesarean section (CS) was noted in women with 25(OH)D ≥10 ng/mL compared to those with 25(OH)D < 10mg/ml (p= 0.01). Conclusion: A high prevalence of vitamin D deficiency was observed in early pregnancy which was related to dress code, use of multi-vitamins and season at sampling. Low 25(OH)D levels were not related with adverse pregnancy outcomes. Women with severe vitamin D deficiency were more likely to deliver vaginally.Publication Metadata only Laparoscopic-assisted live donor nephrectomy: A comparison of conventional and transvaginal routes for kidney extraction(2015-10-22T00:00:00Z) GÜNER CAN, Meltem; ÖZCAN, Pınar; Hatipoglu, Sinan; Cavdaroglu, Ozgur; Hatipoglu, Filiz; BERBER, İbrahim; ÇAKIR, Ülkem; ÖZCAN, PINAR© Ann Transplant, 2015.Backround: Laparoscopic approach has become the standard procedure for living donor nephrectomy in many transplant centers. Because the conventional approach results in cosmetic problems and pain during laparoscopic live donor nephrectomy, transvaginal extraction of an intact kidney has been recently introduced as a minimally invasive technique. Here, we aimed to investigate whether transvaginal extraction of an intact kidney during laparoscopic live donor nephrectomy is associated with decreased postoperative pain, nausea and vomiting, and morphine consumption. Material/Methods: This prospective data analysis included a total of 27 female donors who underwent laparoscopic removal of a single kidney for living donor nephrectomy through conventional or transvaginal route. Data collected included age, body mass index, ASA scores, histocompatibility, additional medical disorders, peri- and postoperative complications, postoperative pain scores with visual analogue pain scores (VAS), length of postoperative stay, morphine consumption, degree of nausea and vomiting, level of sedation, and pruritus. Results: No significant differences between the transvaginal and conventional groups were observed in VAS scores and morphine consumption at postoperative 1, 3, 6, 12, and 24 hours. Although not reaching statistical significance, according to analysis of morphine consumption, there was a trend toward decreasing analgesic requirements in the transvaginal group at postoperative 12 and 24 hours. There were no significant differences between the groups in terms of degree of nausea or vomiting, or length of postoperative hospital stay. Conclusions: We suggest that with a more desirable cosmetic result, transvaginal natural orifice transluminal endoscopic surgery-assisted living donor nephrectomy (TVNALDN) is a suitable new minimally invasive laparoscopic technique associated with reduced postoperative pain and analgesic requirements in select women.Publication Metadata only The predictive value of weight gain and waist circumference for gestational diabetes mellitus(2019-09-01T00:00:00Z) TAKMAZ, TAHA; Yalvac, Ethem Serdar; ÖZCAN, Pınar; Coban, Ulas; Karasu, AYŞE FİLİZ; Unsal, Mehmet; TAKMAZ, TAHA; ÖZCAN, PINAR; GÖKMEN KARASU, AYŞE FİLİZObjective: The first objective of this study was to investigate the relationship between gestational diabetes mellitus (GDM) and gestational weight gain (WG), waist circumference (WC), prepregnancy, and gestational body mass index (BMI). The second aim of our study was to assess the ability of WG, WC, prepregnancy, and gestational BMI with special reference to their cut-off points on predicting the risk of GDM in pregnant women in Turkey.Publication Open Access Can Coenzyme Q10 supplementation protect the ovarian reserve against oxidative damage?(2016-09-01) OZCAN, PINAR; Ficicioglu, Cem; Kizilkale, Ozge; Yesiladali, Mert; Tok, OLGU ENİS; Ozkan, Ferda; Esrefoglu, MUKADDES; ÖZCAN, PINAR; TOK, OLGU ENİS; EŞREFOĞLU, MUKADDESPurpose: We investigated antioxidant effects of CoQ10 supplementation on the prevention of OS-induced ovarian damage and to evaluate the protective effect of such supplementation against OS-related DNA damage. Methods: Twenty-four adult female Sprague-Dawley rats were randomly divided into three groups (8 rats per group): group 1 (control): saline, ip, and orally; group 2 (cisplatin group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days; and group 3 (cisplatin + CoQ10 group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days, and 24 h before cisplatin, 150 mg/kg/day orally in 1 mL of saline daily for 14 days. Serum concentrations of anti-Mullerian hormone (AMH), number of AMH-positive follicles, the assessment of the intensity of 8'OHdG immunoreactivity, the primordial, antral and atretic follicle counts in the ovary were assessed. Result(s): The mean serum AMH concentrations were 1.3 ± 0.19, 0.16 ± 0.03, and 0.27 ± 0.20 ng/mL in groups 1, 2, and 3, respectively (p < 0.01). Serum AMH levels were significantly higher in group 1 compared to groups 2 and 3 (p < 0.01 and p = 0.01, respectively). There was a statistically significant difference in AMH-positive follicle count between the groups (p < 0.01). Group 1 showed higher numbers of AMH-positive granulosa cells compared to group 2 (p = 0.01). A significant difference was found in the primordial, the atretic, and antral follicle counts between the three groups (p < 0.01, p < 0.01, and p < 0.01, respectively). The atretic follicle count was significantly lower in the cisplatin plus CoQ10 group compared to the cisplatin group (p < 0.01). The antral follicle counts were significantly higher in the cisplatin plus CoQ10 group compared with the cisplatin group (p < 0.01). There was a statistically significant difference in the intensity of staining of the follicles that were positive for anti-8'OHdG between the groups (p = 0.02). Group 1 showed a significant lower intensity of staining of the follicles positive for anti-8'OHdG compared with group 2 (p = 0.03). Conclusion(s): CoQ10 supplementation may protect ovarian reserve by counteracting both mitochondrial ovarian ageing and physiological programmed ovarian ageing although the certain effect of OS in female infertility is not clearly known.Publication Open Access Analysis of preoperative and postoperative quality of life, sexual function, and sleep in patients with endometriosis: a prospective cohort study(2022-04-01T00:00:00Z) Halici, Belfin Nur Arici; Aktoz, Fatih; Kabakci, Meric; KIRAN, Gürkan; ÖZCAN, PINAR; KIRAN, GÜRKAN; ÖZCAN, PINARPurpose 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.
