Öğe Association of omentin Val109Asp polymorphism with coronary artery disease(2014) Karabacak, Ahmet; Başar, Cengiz; Bulur, Serkan; Aslantaş, Yusuf; Özhan, Hakan; Memişoğulları, Ramazan; Kaya, ErtuğrulObjective: Coronary artery disease (CAD) is the most important morbidity and mortality disease in the world. It is also one of the leading causesof death in Turkey. Omentin, a recently found adipocytokine, is reported to regulate insulin sensitivity. It has anti-inflammatory properties and isinversely associated with CAD. Omentin gene polymorphism in patients with CAD has not been studied yet. The aim of this study is to investigatethe relationship between omentin Val109Asp polymorphism and CAD.Methods: This is an observational study on genetic association. 157 consecutive patients who had undergone coronary angiography wereincluded in the study. Seventy-five of them had CAD and the rest serves the control group. Val109Asp polymorphism was analyzed and com-pared. Chi-square test was used in comparison of genotype frequencies, whereas ANOVA and chi-square tests were used in comparison ofclinical characteristics according to the genotypes.Results: There was no significant difference between CAD patients and control subjects regarding omentin Val109Asp polymorphism. However, a 2.5fold increase in Val/Val (homozygous mutant) genotype was detected in patients with CAD. The OR (80% Cl) for Val/Val genotype was 3.46 (1.14-10.49).Conclusion: Although no significant difference was detected regarding omentin Val109Asp polymorphism, Val/Val genotype frequency was found to bemore in patient group than control group. In conclusion, it may be speculated that Val/Val genotype increases the tendency for CAD, but this experimentshould done with larger population to clarify this issue.Öğe Öğe MELEN study: Rationale, methodology and basic results(Tıp Araştırmaları Derneği, 2011) Aydın, Yusuf; Özhan, Hakan; Albayrak, Sinan; Türker, Yasin; Bulur, Serkan; Erden, İsmail; Beşir, Fahri Halit; Çil, HabipAim: The aim of the Melen Study was to investigate the cardiovascular risk profile of Turkish adults by utilizing newest techniques. Besides prevalence and types of endemic goiter will be established which was an important health problem in the Black sea region Method: The study was conducted on 2230 participants (1427 women, 803 men with a mean age of 49). The participants underwent a Doppler Ultrasound examination of carotid intima media thickness, echocardiographic examination, ECG recording, bioempedance meter analysis of body composition, pulmonary function test and various biochemical analysis. Result: Twenty nine percent of the population had hypertension, 12% had diabetes mellitus and 17% were smokers. Thyroid ultrasonography revealed that 29% of the cohort had goiter. Echocardiographic measurements showed that 39% of the participants had diastolic dysfunction. Comparison of males with females showed that men had significantly higher visceral fat, triglyceride, hemoglobin and CIMT whereas women had higher mean diastolic blood pressure, HDL and total cholesterol. Conclusion: According to the histories of patients, hypertension, diabetes mellitus and smoking were very frequent among Turkish adults. Among the objectively measured variables, diastolic dysfunction, visceral adiposity and goiter were strikingly high.
