    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, PINAR
    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.

    The Role of the Urine Dipstick Test in the Detection of Abnormal Proteinuria Using Different Cut-off Levels in Hypertensive Pregnancies Hipertansif Gebeliklerde Farklı Kesim Değerleri Kullanılarak Anormal Proteinüri Saptanmasında Spot İdrar Protein Ölçümünün Rolü
    (2022-01-01) Takmaz T.; Gorchiyeva I.; Arici Halici B. N.; TOPRAK A.; ÇETİN Ç.; KÜTÜK M. S.; TAKMAZ, TAHA; ARICI HALICI, BELFİN NUR; TOPRAK, ALİ; ÇETİN, ÇAĞLAR; KÜTÜK, MEHMET SERDAR
    © 2022, Duzce University Medical School. All rights reserved.Aim: The aim of this study was to determine the diagnostic accuracy of different urine dipstick protein threshold levels in predicting the presence of abnormal proteinuria in pregnant women with hypertension. Material and Methods: A total of 326 singleton pregnant women who underwent 501 urine protein tests and who had suspected preeclampsia were included in this retrospective study. Patient data was taken including medical and obstetric history. The results of dipstick urinalysis and concurrent 24-hour urine protein excretion measurements were compared to determine the accuracy of urinalysis. Results: A dipstick result of 1+ was found to be the best cut-off to predict 500 mg of protein excretion per day, with sensitivity and specificity of 62.09% and 88.97%, respectively. A 2+ proteinuria dipstick cut-off had high specificity and positive predictive value (PPV) (99.05% and 98.84%, respectively) for the prediction of 300 mg of protein excretion per day; this cut-off had low sensitivity (21.46%). A cut-off of 1+ also provided satisfactory specificity and PPV (91.43% and 94.48%, respectively) for the detection of 300 mg of protein excretion per day, but sensitivity was compromised (38.89%). Among 301 patients with negative dipstick results, 212 had a 24-hour urine protein extraction greater than 300 mg, with a false negative rate of 70.43%. Conclusion: The results suggest that the urine protein dipstick measurement has limited quantitative ability for the prediction of abnormal proteinuria. Additionally, the use of 500 mg 24-hours protein excretion as a cut-off value for abnormal proteinuria may provide useful data.

    (2023-12-01) Özçelik C.; VARLI B.; Gökçe A.; Takmaz T.; ÇETİN Ç.; ÖZCAN P.; TAKMAZ, TAHA; ÇETİN, ÇAĞLAR; ÖZCAN, PINAR
    PURPOSE: 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.

    (2022-05-01T00:00:00Z) ATEŞ, SEDA; Aydin, Serdar; ÖZCAN, PINAR; BAKAR, Rabia Zehra; ÇETİN, ÇAĞLAR; ATEŞ, SEDA; ÖZCAN, PINAR; BAKAR, RABIA ZEHRA; ÇETİN, ÇAĞLAR
    Purpose To assess sleep disturbances, levels of anxiety, depression and fatigue in women with premature ovarian insufficiency (POI). Materials and methods The study included 62 women with POI and 62 age-matched controls. Women in both groups completed questionnaires. Pittsburgh Sleep Quality Index, Insomnia severity index, Epworth Sleepiness Scale, Hospital Anxiety and Depression Scale and Fatigue Severity Scale were used. Results We found poor sleep quality, higher levels of insomnia in women with POI than in controls. Depression was much more prevalent and severe in POI women. Total anxiety score, the severity of anxiety and fatigue did not differ significantly between the groups. According to the multivariable logistic regression analysis, being married and having POI were associated with worse quality of sleep, and having more children was associated with an increase in depression levels in the whole cohort. Backward analysis showed that when POI status was taken as a reference, married women were at 6.5 fold increased risk of poor sleep quality. Conclusions Women with premature ovarian failure are more likely to suffer from poor sleep quality, insomnia and depression than healthy women.

    The importance of serum progesterone concentration at embryo transfer day and effect of rescue additional progesterone during programmed artificial frozen embryo transfer cycles
    (2022-01-01T00:00:00Z) ÖZCAN, PINAR; ÇETİN, ÇAĞLAR; Okten, Berkem; TANOĞLU, FATMA BAŞAK; Taha, Havva Sevde; Pasin, Ozge; Ficicioglu, Cem; ÖZCAN, PINAR; ÇETİN, ÇAĞLAR; TANOĞLU, FATMA BAŞAK; PASİN, ÖZGE
    © 2022 Reproductive Healthcare Ltd.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.

    The effects of maternal smoking on fetal cranial development. Findings from routine midtrimester sonographic anomaly screening
    (2023-12-01) ÇETİN Ç.; BAKAR R. Z.; Takmaz T.; PASİN Ö.; KÜTÜK M. S.; ÇETİN, ÇAĞLAR; BAKAR, RABIA ZEHRA; PASİN, ÖZGE; KÜTÜK, MEHMET SERDAR
    The aim of this study was to assess the effect of continued smoking before and during pregnancy on mid-trimester fetal head development. A total of 250 pregnant women enrolled in the study. All participants were confirmed to be smokers or non-smokers by verifying breath carbon monoxide readings. Biparietal diameter (BPD), head circumference (HC), lateral ventricle (LV), and cisterna magna (CM) were evaluated by ultrasound between 20-22 weeks of pregnancy. Gender and gestational age-adjusted BPD z- scores were not statistically different between smokers and non-smokers (-0.75 ± 1.6 vs -0.51 ± 1, p = .3). HC measurements and z- scores were significantly lower in the smoking group than in the non-smoking groups (183.38 ± 14.56 vs. 189.28 ± 12.53, p = .003, 0.18 ± 1.39 multiple of median (MoM) vs. 0.56 ± 0.92, respectively, p = .023). At linear regression analysis, maternal smoking was the only independent factor associated with fetal HC z score (p = .041). In conclusion, continued smoking during pregnancy reduces fetal HC and has no effect on BPD, LV, or CM measurements at mid-gestation.IMPACT STATEMENTWhat is already known on this subject? Smoking during pregnancy is one of the most common environmental factors affecting fetal and neonatal growth and well-being. Despite the well-known effects of smoking on somatic growth, current studies have shown that it selectively affects some parts of the fetal brain, even in appropriately growing fetuses.What do the results of this study add? Continued smoking during pregnancy reduces fetal HC and has no effect on BPD, LV or CM measurements at mid-gestation. Since smoking is well known for its early and late childhood behavioral and neurological consequences, smaller mid-trimester fetal HC measurements should bring maternal smoking to mind as one of the potentially reversible causes.What are the implications of these findings for clinical practice and/or further research? The harmful effects of smoking start before the third trimester and antenatal counseling should be started early in the gestation. Every effort should be made to quit smoking before or early in pregnancy.

    Intrauterine Insemination, IVF/ICSI Intrauterin Inseminasyon, IVF/ICSI
    (2022-10-30) ÇETİN Ç.; ÖZCAN P.; ÇETİN, ÇAĞLAR; ÖZCAN, PINAR
    © 2022, Duzce University Medical School. All rights reserved.Infertility is defined as the inability to conceive after one year despite regular intercourse. The need for treatment and treatment option are determined by the evaluation process that starts after this stage. Treatment mainly includes ovarian stimulation followed by timed intercourse, intrauterine insemination (IUI), and in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). Choosing the appropriate patient and appropriate treatment method is critical here and is based on many factors. Maternal age and infertility etiology are the main determinants of treatment selection. As important as it is to think about IVF/ICSI selection quickly in patients over 38 years of age, it is equally important to switch to assisted reproductive techniques without waiting in the presence of very low sperm parameters. An inappropriate indication will fail even if the treatment is done in the best way. Appropriate patient selection and giving enough time to the patient in the treatment stages will increase success. In the presented article, IUI and IVF/ICSI patient selection criteria will be evaluated according to the causes of infertility. Here, the order in which the patient will be evaluated and the steps to be taken on the way to IVF/ICSI in the treatment of staged infertility will be evaluated in detail and descriptively.
