Item Echocardiographic Epicardial Adipose Tissue Measurements Provide Information About Cardiovascular Risk in Hemodialysis Patients(2015) Ulusal Okyay, Gulay; Okyay, Kaan; Polattas Solak, Evsen; Sahinarslan, Asife; Pasaoglu, Ozge; Ayerden Ebinc, Fatma; Pasaoglu, Hatice; Boztepe Derici, Ulver; Sindel, Sukru; Arinsoy, Turgay; 0000-0001-6134-8826; 25643907; AAK-7355-2020Epicardial adipose tissue (EAT) is a cardiovascular risk predictor in general population. However, its value has not been well validated in maintainance hemodialysis (MHD) patients. We aimed to assess associations of EAT with cardiovascular risk predictors in nondiabetic MHD patients. In this cross-sectional study, we measured EAT thickness by transthoracic echocardiography in 50 MHD patients (45.8 +/- 14.6 years of age, 37 male). Antropometric measurements, bioimpedance analysis, left ventricular (LV) mass, carotis intima media thickness, blood tests, homeostasis model assessment for insulin resistance (HOMA-IR) and hemodialysis dose by single-pool urea clearence index (spKt/V) were determined. The mean EAT thickness was 3.28 +/- 1.04mm. There were significant associations of EAT with body mass index (=0.590, P<0.001), waist circumference (=0.572, P<0.001), body fat mass (=0.562, P<0.001), percentage of body fat mass (=0.408, P=0.003), percentage of lean tissue mass (=-0.421, P=0.002), LV mass (=0.426, P=0.002), carotis intima media thickness (=0.289, P=0.042), triglyceride/high-density lipoprotein cholesterol ratio (=0.529, P<0.001), 1/HOMA-IR (=-0.386, P=0.006), and spKt/V (=-0.311, P=0.028). No association was exhibited with visfatin C, high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-alpha (for all, P>0.05). Body mass index, waist circumference, body fat mass, percentage of lean tissue mass, LV mass, triglyceride/high-density lipoprotein cholesterol ratio, HOMA-IR, and spKt/V appeared as independent predictors of EAT. EAT was significantly associated with body fat measures, cardiovascular risk predictors, and dialysis dose in MHD patients.Item Heart-type fatty acid binding protein levels in elderly diabetics without known cardiovascular disease(2017) Beysel, S.; Kizilgul, M.; Ozbek, M.; Caliskan, M.; Kan, S.; Apaydin, M.; Ozcelik, O.; Cakal, E.; 29255351Background: Cardiovascular disease (CVD) is reported to be higher in elderly diabetics. Serum heart-type fatty acid binding protein (H-FABP) is a serum marker of myocardial ischemia. We aimed to investigate the association between serum H-FABP level and conventional cardiovascular risk factors, inflammatory markers and subclinical atherosclerosis in elderly diabetics without overt CVD. Patients and methods: A total of 50 elderly diabetic patients without overt CVD and 30 age-, sex- and body mass index (BMI)-matched healthy controls were enrolled. Anthropometric and biochemical parameters, serum H-FABP, high-sensitivity C-reactive protein (hs-CRP), fibrinogen and carotid intima-media thickness (CIMT) were measured. Logistic regression analyses (adjustments for age, sex, hypertension, smoking, diabetes, BMI, blood pressure, lipid, blood glucose, hemoglobin A1c, hs-CRP and fibrinogen) were performed to evaluate the association between H-FABP and cardiovascular risk factors and atherosclerosis indices. Results: Serum fibrinogen (421.50±85.52 mg/dL vs 319.17±30.77 mg/dL, p=0.023), CIMT (0.70±0.12 mm vs 0.59±0.06 mm, p<0.001) and hs-CRP (5.72±4.50 mg/dL vs 1.60±0.72 mg/dL, p<0.001) were significantly higher in diabetic patients than controls. The mean serum H-FABP level did not differ between groups (1571.79±604.60 ng/mL vs 1500.25±463.35 ng/mL, p=0.905). H-FABP was positively correlated with fibrinogen (r2=0.473, p<0.001), hs-CRP (r2=0.323, p=0.003) and CIMT (r2=0.467, p<0.001). After full adjustments, the serum H-FABP level was independently associated with an increase in the fibrinogen level (odds ratio [OR] =4.21, 95% confidence level [CI] =1.49-11.90). Conclusion: Serum H-FABP was similar in the elderly diabetic patients without known CVD when compared with the nondiabetic control group. H-FABP does not possess a high diagnostic value as a cardiovascular marker when used alone; however, it may add supplementary information in patients with a high fibrinogen level. © 2017 Beysel et al.Item Effects of significant weight loss following bariatric surgery on red cell distribution width and mean platelet volume(2018) Altın, C.; Erol, V.; Yılmaz, M.; Bozkuş, Y.; Müderrisoğlu, H.Aim: Elevated red blood cell distribution width (RDW) and mean platelet volume (MPV) levels which are closely associated with chronic inflammation and platelet aggregation are suggested as independent predictors of obesity and cardiovascular diseases. However influence of significant weight loss following bariatric surgery on these parameters is unknown. Therefore we aimed to find out the effect of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on RDW and MPV levels. Methods: The medical data of 98 morbid obese subjects (25 male, 73 female) who were operated between February 2015 and June 2017 according to indications of bariatric surgery in current guidelines including body mass index (BMI) >40 kg/m 2 or BMI= 35-40 kg/ m 2 with additional comorbidities were recorded. The difference between baseline and values at one year was expressed as a delta (Δ). Results: The mean age of our study population was 41.89±11.99 years and mean weight loss in one year after LSG was 45.41±13.13 kg (36.5%). BMI decreased from 46.60±7.11 kg/m 2 to 29.58±4.63 kg/m 2 . Compared to the baseline, significant decreases in RDW (14.61±1.69 % vs. 13.71±2.10 %; p<0.01) and MPV (8.63±1.45 vs. 7.92±1.24 fL, p<0.001) levels were found in the postoperative one-year values. In addition; ΔVKI was positively correlated with ΔRDW (r=0.343, p<0.01) and ΔMPV (r=0.322, p<0.01). Conclusion: We found that morbid obese subjects have significantly decreased RDW and MPV levels which are correlated to their weight loss in one-year follow-up after LSG. If we think that several factors may affect these parameters, conduction of further prospective large-scale studies are needed. © 2018, Logos Medical Publishing.

However, the pathogenesis of this relationship is still inexplicit. The link between cardiac diseases and comorbid migraine-ischemic stroke might be a vascular disease involving both heart and brain. In this study, an association between mitral valve prolapse (MVP), migraine, and the presence of brain white matter hyperintensities (WMHs) were evaluated among adult subjects with migraine headache devoid of any traditional vascular risk factors. Materials and Methods: Four hundred subjects (200 subjects with migraine headache, 200 healthy controls; age range 18-50 years) were incorporated in the retrospective study. Existence of a headache compatible with migraine was diagnosed according to the International Headache Society-2 criteria. The participants were devoid of any known comorbid diseases, vascular risk factors or inflammatory diseases. All patients, both those with migraine and controls were screened with echocardiography to assess for MVP and with brain magnetic resonance imaging co evaluate the presence of any WMHs. Results: The prevalence of MVP was found to be higher in the migraine group (p<0.011). The odds ratio (OR) for the presence of MVP in patients with migraine compared with controls was 2.44 [95% confidence interval (CI): 1.25-4.74; p=0.0086]. The OR for the presence of WMHs in patients with migraine compared with controls was 5.88 (95% CI: 3.42-10.10; p<0.0001). After modifying for confounding factors, multiple linear regression analyses revealed that migraine was independently and positively associated with MVP (p=0.044), tricuspid regurgitation (p=0.003), and WMHs (p<0.001), and mitral regurgitation and migraine was independently and positively connected with WMHs (p<0.005 and p<0.001, respectively). Conclusion: MVP is found CO be independently associated with migraine when compared with controls. Therefore, we suggest that MVP might have an association with migraine. Nevertheless, we could not demonstrate any correlation between MVP and WMHs. Hence, we suggest that MVP might nor be involved in the evolution of WMHs in migraine
