Item Previous Gestational Diabetes History is Associated with Impaired Coronary Flow Reserve(2015) Caliskan, Mustafa; Turan, Yasar; Caliskan, Zuhal; Gullu, Hakan; Ciftci, Faika Ceylan; Avci, Enver; Duran, Cevdet; Kostek, Osman; Caklili, Ozge Telci; Koca, Harun; Kulaksizoglu, Mustafa; 0000-0003-2579-9755; 26555575; IXD-5147-2023Background Gestational diabetes mellitus (GDM) is a prediabetic state that is known to increase the risk of cardiovascular diseases. We have investigated coronary flow velocity reserve (CFVR) and epicardial fat thickness (EFT), and left ventricular diastolic function in patients with a history of previous GDM (p-GDM). Methods Ninety-three women with GDM history and 95 healthy women without GDM history were recruited. We used transthoracic Doppler echocardiography to assess CFVR, EFT, and left ventricular diastolic function. Insulin resistance of each subject was assessed with homeostasis model assessment insulin resistance (HOMA-IR). Hemoglobin A1c and high-sensitivity C-reactive protein (hsCRP) were also measured in all patients. Results CFVR values were significantly lower (2.34 +/- 0.39 versus 2.80 +/- 0.24, p<0.001) and EFT values were significantly higher in patients with p-GDM than the control group (5.5 +/- 1.3 versus 4.3 +/- 1.1, p<0.001). E/E' ratio (7.21 +/- 1.77 versus 6.53 +/- 1.38, p = 0.003), hemoglobin A1c (5.2 +/- 0.4 and 5.0 +/- 0.3, p = 0.001), HOMA-IR (2.8 +/- 1.4 versus 1.7 +/- 0.9, p = 0.04), and hsCRP levels were significantly higher in the p-GDM group than the control group. Multivariate analysis revealed that gestational diabetes history is independently associated with CFVR. Conclusion Women with a GDM history may be at more risk regarding coronary microvascular dysfunction compared to the healthy ones.Item Is Late Adolescence A Real Risk Factor for An Adverse Outcome of Pregnancy?(2016) Ozdemirci, Safak; Kasapoglu, Taner; Cirik, Derya Akdag; Yerebasmaz, Neslihan; Kayikcioglu, Fulya; Salgur, Funda; 0000-0001-5502-7751; 26767509; AAE-7154-2021; AAI-8762-2021Objective: To compare the obstetrical and neonatal outcomes of late adolescent (LA) and adult pregnancies.Methods: Between January 2012 and December 2012, a total of 313 late adolescent pregnant aged between 16 and 19 years and 418 adult pregnant women aged between 20 and 35 years having given birth in our maternity service were enrolled into this case-control study. The demographic and clinical data were reviewed from hospital database and patients' medical records.Results: The incidence of preterm birth (PB) in the LA group was significantly higher than in the adult group (p=0.001), while the incidence of gestational diabetes mellitus was significantly lower (p=0.001). The mean birth weight and the rate of delivered macrosomic fetuses in the study group were lower than in the control group (p=0.03). The LA group had significantly higher rate of vaginal delivery when compared to the adult group (p=0.001). Both the rate of pregnancy induced hypertensive disorders and postpartum hemorrhage were not statistically different between the two groups (p=0.31; p=0.38, respectively). The LA group had lower rate of stillbirth when compared to the adult group; however, the difference was statistically insignificant (0.3% versus 1.2%) (p=0.24).Conclusions: The LA pregnancy should be closely followed up during their antenatal care period due to the significantly higher rate of PB.Item Measuring Visfatin Levels in Saliva: An Alternative Approach to Gestational Diabetes Screening(2021) Bildaci, Tevfik Berk; 34762778Objective: Oral glucose tolerance testing (OGTT) is the current recommended approach for the diagnosis of gestational diabetes mellitus (GDM). Visfatin is a type of novel adipokine of interest that mostly participates in glucose metabolism and inflammatory processes. We aim to identify a screening technique for GDM using salivary visfatin levels and to establish this technique's value as a screening method compared to OGTT. Materials and methods: This is a cross-sectional case-control study.The cohort was formed from the saliva samples of pregnant patients in their 24th through 28th weeks of gestation. Patients were divided into two groups depending on their GDM status. OGTT and visfatin test results were compared and subjected to further analysis to establish a cutoff value for visfatin testing. Results: ELISA results indicated a significant difference between patients with GDM compared to patients without GDM; the values were 18.89 +/- 9.59 and 12.44 +/- 8.75, respectively (p: 0.007). A cutoff value of 10.5 ng/mL can be used to detect GDM with 78% sensitivity and 51% specificity. Conclusion: Salivary visfatin levels were significantly higher in patients with GDM. The existence of a differential in the concentration of visfatin in saliva can be utilized to develop a new screening method for GDM.Item Salivary Leptin and Chemerin; a novel way of gestational diabetes screening(2020) Okten, Sabri Berkem; Bildaci, Tevfik Berk; 0000-0001-7473-761X; 32274942Introduction: Oral glucose tolerance testing (OGTT) is the recommended approach for the diagnosis of gestational diabetes mellitus (GDM). Leptin and chemerin are two examples of hormones from adipokine family, which mostly takes part in glucose metabolism and inflammatory processes. We aim to find a possible new and tolerable screening technique for GDM using salivary levels of leptin and chemerin. Material and method: Saliva samples of pregnant patients, on their 24-28th weeks of gestation, are collected via saliva collection kit. Leptin and chemerin ELISA tests were run from serum samples being hold at -80 degrees C following their thawing session. Patients are divided into two groups depending on their GDM status. OGTT results of patients are compared with their ELISA results. Results: ELISA study for leptin showed an insignificant difference between patients with GDM and patients without where the values were 0.44 +/- 0.33 and 0.34 +/- 0.24 respectively (p: 0.155). Chemerin study revealed a significant difference between patients with GDM and without 631.06 +/- 344.42, 334.81 +/- 244.91 respectively (p < .001). Conclusion: Leptin and chemerin can be detected in saliva. Chemerin levels are significantly higher in patients with GDM, thus this knowledge can be used to develop a new screening method for OGTT.
