ObjectiveaaThe aim of this study was to investigate whether cortisol and oxidative stress levels and DNA damage differ between individuals who developed PTSD or not following a sexual trauma. MethodsaaThe study included 61 children aged between 5 and 17 years who sustained sexual abuse (M/F: 18/43). The patients were divided into two groups: patients with PTSD and patients without PTSD based, based on the results of a structured psychiatric interview (K-SADS-PL and CAPS-CA). Cortisol, glutathione peroxidase (GPx), superoxide dismutase (SOD), coenzyme Q, 8-Hydroxy-2-Deoxyguanosine (8-OHdG) were all evaluated by the ELISA method. ResultsaaOur evaluation revealed a diagnosis of PTSD in 51% (n=31) of victims. There was no significant difference between the groups with or without PTSD in terms of cortisol, GPx, SOD, coenzyme Q, and 8-OHdG levels. There was no correlation between CAPS scores and GPx, SOD, coenzyme Q, and 8-OHdG levels between patients with or without PTSD. In patients with PTSD, both cortisol and 8-OHdG levels decreased with increasing time after trauma, and there was no significant correlation with cortisol and 8-OHdG levels in patients without PTSD. ConclusionaaAlthough the present study did not find any difference between the groups in terms of 8-OHdG concentrations, the decreases in both cortisol and 8-OHdG levels with increasing time after trauma is considered to indicate a relationship between cortisol and DNA damage.

Background and Objectives: Left ventricular hypertrophy (LVH), a sign of subclinical cardiovascular disease, is an important predictor of cardiovascular morbidity and mortality. The aim of our study was to determine the association of left ventricular mass (LVM) with possible causative anthropometric and biochemical parameters as well as carotid intima-media thickness (CIMT) and brachial flow-mediated dilation (FMD) as surrogates of atherosclerosis and endothelial dysfunction, respectively, in previously untreated hypertensive patients. Subjects and Methods: Our study included 114 consecutive previously untreated hypertensive patients who underwent echocardiography and ultrasonography to evaluate their vascular status and function via brachial artery CIMT and FMD. Results: Among all study parameters, age, systolic blood pressure (BP), diastolic BP, pulse pressure, plasma glucose, uric acid, total bilirubin, direct bilirubin, hemoglobin, and CIMT were positively correlated with the LVM index. Multiple logistic regression analysis revealed that office systolic BP, age, male gender, and total bilirubin were independent predictors of LVH. Conclusion: Bilirubin seems to be related to LVM and LVH. The positive association of bilirubin with these parameters is novel and requires further research.
