Item Serum and placental periostin levels in women with early pregnancy loss(2020) Eroglu, Semra; Colak, Eser; Erinanc, Ozgur Hilal; Ozdemir, Duygu; Ceran, Mehmet Ufuk; Tasdemir, Umit; Kulaksizoglu, Sevsen; Ozcimen, Emel Ebru; 0000-0003-1401-6356; 0000-0002-7613-2240; 0000-0002-9959-9433; 32460058; AAL-1268-2021; AAI-8932-2021Objectives: Periostin is secreted from the placenta in the embryonic period and it is emphasized that it may be involved in endometrial implantation. In this study, we aimed to investigate periostin serum levels and placental tissue expression in first trimester pregnancy losses. Study design: In this prospective case-control study, 30 patients who underwent dilatation and curettage with first trimester spontaneous abortion (< 10 weeks of gestation) were included in the study group and 30 patients who had voluntary pregnancy termination (< 10 gestational weeks) were included in the control group. Serum samples collected from the study and control groups were analyzed usingenzyme-linkedimmunosorbent assay (ELISA), and trophoblastic and decidual tissues were examined using immunohistochemical staining with streptavidin-biotin-peroxidase techniques. Results: There were no significant differences between the groups in terms of age, gravida status, parity number, gestational week, and number of previous abortions. In the spontaneous abortion group, the serum level of periostin was significantly lower than in the voluntary termination group (6.56 +/- 4.16 pg/mLvs. 9.51 +/- 4.52 pg/mL, p = 0.03). There was no significant difference between the two groups in terms of periostin expression in decidual and trophoblastic tissue (p = 0.617, p = 0.274, p = 0.497). Conclusion: Periostin serum levels were significantly reduced in patients with spontaneous pregnancy loss. Periostin can be used as a predictive marker for the success of endometrial implantation.Item Role of mean platelet volume in pregnancy to predict gestational diabetes mellitus in the first trimester(2020) Colak, Eser; Ozcimen, Emel Ebru; Ceran, Mehmet Ufuk; Tohma, Yusuf Aytac; Kulaksizoglu, Sevsen; 0000-0001-9418-4733; 0000-0002-7613-2240; 0000-0003-1923-2373; 0000-0002-8184-7531; 30947572; AAE-6482-2021; AAI-8932-2021Objectives:Gestational diabetes mellitus (GDM) is defined as glucose intolerance detected for the first time in pregnancy or identified during pregnancy. Mean platelet volume (MPV) is a marker of activation and function of platelet. Several studies investigated the relation between MPV and GDM. The purpose of the present study is to predict GDM in the first trimester by using MPV value. Materials and methods:Two hundred pregnant women with GDM and 200 normal pregnant women were enrolled in the study. The first trimester MPV values of GDM and control groups were compared to predict GDM in the first trimester. Results:Women with GDM had higher MPV value compared with the control group (p < .001). The area under the receiver-operator curve was 0.70 for MPV. The cutoff value of MPV was 7.38 fl with 70% sensitivity and 60% specificity. According to the ages, MPV value was higher in GDM group in the individuals who were above 28-year-old (p < .001). Conclusion:MPV can be used to predict GDM in the first trimester.Item May myo-inositol andd-chiro-inositol (40:1) treatment be a good option on normal-weighted polycystic ovary syndrome patients without insulin resistance?(2020) Colak, Eser; Ozcimen, Emel Ebru; Tohma, Yusuf Aytac; Ceran, Mehmet Ufuk; 0000-0002-8184-7531; 32989863Aim To investigate the effectiveness of myo-inositol andd-chiro-inositol (MI:DCI) (40:1) treatment in normal-weight polycystic ovary syndrome (PCOS) patients without insulin resistance. Methods This retrospective case-control study included PCOS patients without insulin resistance who were diagnosed in the gynecology and obstetrics clinic of Baskent University Konya Practice and Research Hospital between January 2016 and October 2019 and received at least 6 months of MI:DCI (40:1) treatment. The patients were divided into two groups according to body mass index (BMI). Twenty-nine anovulatory patients without insulin resistance with a BMI of 18-25 were included in group 1 (normal-weight group), whereas 17 patients without insulin resistance with BMI > 25 were included in group 2 (obese/overweight group). Ovulation status of both groups was compared after MI:DCI treatment. Results Ovulation was detected in 23 of 29 patients in the normal-weight group, whereas it was detected only in 5 of 17 patients in the obese/overweight group; this difference was statistically significant (P < 0.001) (Table 2, Figure 1). Post-treatment progesterone levels of both groups were compared and in the normal-weight PCOS group was significantly higher than the obese/overweight group (P < 0.001) (Table 2, Figure 2). In addition, spontaneous pregnancy following treatment was observed in six of the seven (85.7%) patients in the normal-weight group who wanted to conceive, whereas it was observed in only two of the six (33.3%) patients in the obese/overweight group who wanted to conceive. Conclusion Our results showed that MI:DCI (40:1) treatment may be a first-line treatment in normal-weight PCOS patients without insulin resistance.Item Vitamin D receptor gene TaqI single nucleotide polymorphism is not associated with lead levels in maternal and umbilical cord blood(2019) Tohma, Yusuf Aytac; Akad, Selin; Colak, Eser; Kulaksizoglu, Sevsen; Akyol, Mesut; Terzi, Yunus Kasim; Ozcimen, Emel Ebru; Esin, Sertac; Sahin, Feride Iffet; 0000-0001-5612-9696; 0000-0001-7308-9673; 0000-0002-3808-7004; 0000-0001-9418-4733; 0000-0002-8184-7531; 29463156; AAC-8356-2020; B-4372-2018; AAC-7232-2020Purpose: We aimed to investigate the association of vitamin D receptor (VDR) gene TaqI single nucleotide polymorphism (SNPs) with serum lead (Pb) levels in maternal and umbilical cord blood. Materials and methods: Eighty-one patients who lived in Konya, Turkey for the last 3 years and had delivery at Baskent University Konya Hospital in 2016 were included in this study. Venous blood samples were drawn from each volunteer immediately before giving birth to determine the maternal Pb levels and VDR SNPs. Additionally, umbilical cord blood samples were collected from the umbilical vein into tube with EDTA as an anticoagulant immediately after birth to determine Pb levels of the fetus. Results: The median level of Pb in the maternal blood was 29.00 (Interquartile Range (IQR) = 16.35) mu g/L and the median Pb level in the cord blood was 22.50 (IQR = 9.75) mu g/L. Blood Pb level of women living in the urban area was significantly higher than in those living in the rural area (Z = 2.118; p = .034). There was a very strong positive correlation between the Pb levels in the maternal blood and in the umbilical cord blood (rho = 0.825, p < .001, respectively). Regarding VDR SNPs, "TT", "TC", and "CC" VDR TaqI genotypes were observed in 28 (34.6%), 45 (55.5%), and eight samples (9.9%), respectively. Pb levels in maternal and cord blood were higher in women with the "CC" VDR TaqI genotype; however, there was no statistically significant difference (p > .05). Conclusions: Although women with the "CC" VDR TaqI genotype had higher maternal and cord blood Pb levels, this was statistically insignificant and therefore, VDR TaqI SNPs did not significantly affect maternal and umbilical cord blood Pb levels.
