Item Increased monocyte to HDL cholesterol ratio in vitamin B12 deficiency: Is it related to cardiometabolic risk?(2021) Kirnap, Nazli Gulsoy; 32639203Vitamin B12 deficiency may have indirect cardiovascular effects in addition to hematological and neuropsychiatric symptoms. It was shown that the monocyte count-to-high density lipoprotein cholesterol (HDL-C) ratio (MHR) is a novel cardiovascular marker. In this study, the aim was to evaluate whether MHR was high in patients with vitamin B12 deficiency and its relationship with cardiometabolic risk factors. The study included 128 patients diagnosed with vitamin B12 deficiency and 93 healthy controls. Patients with vitamin B12 deficiency had significantly higher systolic blood pressure (SBP), diastolic blood pressure (DBP), MHR, C-reactive protein (CRP) and uric acid levels compared with the controls (median 139 vs 115 mmHg, p < 0.001; 80 vs 70 mmHg, p < 0.001: 14.2 vs 9.5, p < 0.001: 10.2 vs 4 mg/dl p < 0.001: 6.68 vs 4.8 mg/dl, p < 0.001 respectively). The prevalence of left ventricular hypertrophy was higher in vitamin B12 deficiency group (43.8%) than the control group (8.6%) (p < 0.001). In vitamin B12 deficiency group, a positive correlation was detected between MHR and SBP, CRP and uric acid (p < 0.001 r:0.34, p < 0.001 r:0.30, p < 0.001 r:0.5, respectively) and a significant negative correlation was detected between MHR and T-CHOL, LDL, HDL and B12 (p < 0.001 r: -0.39, p < 0.001 r: -0.34, p < 0.001 r: -0.57, p < 0.04 r: -0.17, respectively). MHR was high in vitamin B12 deficiency group, and correlated with the cardiometabolic risk factors in this group, which were SBP, CRP, uric acid and HDL. In conclusion, MRH, which can be easily calculated in clinical practice, can be a useful marker to assess cardiovascular risk in patients with vitamin B12 deficiency.Item Assessment of Carotid Artery Distensibility and Elasticity After Laparoscopic Sleeve Gastrectomy: a Prospective Study(2020) Gunesli, Aylin; Yilmaz, Mustafa; Altin, Cihan; Gezmis, Esin; Yabanoglu, Hakan; Erol, Varlik; 0000-0002-2557-9579; 0000-0002-8337-6905; 0000-0002-1161-3369; 0000-0002-1001-6028; 0000-0003-0268-8999; 32813160; S-6973-2016; AAK-3065-2021; AAJ-7865-2021; AAE-8301-2021; AAK-2011-2021Purpose Although it is well known that obesity increases the risk of atherosclerosis in carotid arteries, it is not clear whether this risk changes after obesity surgery. The aim of this study was to investigate whether weight reduction with a laparoscopic sleeve gastrectomy (LSG) has any effect on distensibility and elasticity which show subclinical atherosclerosis in the carotid arteries of obese individuals. Materials and Methods This prospective study included 130 patients (body mass index (BMI) 48.21 +/- 6.97 kg/m(2)) who underwent LSG. The patients were followed up for 1 year. Comparisons were made of the distensibiliy and elasticity values calculated preoperatively and at 1, 3, 6, and 12 months, postoperatively. Results There was a statistically significant increase in distensibility and elasticity values from baseline to 1, 3, 6, and 12 months postoperatively (p < 0.001 for both comparisons). The multiple linear regression analysis was used to find the variables affecting both distensibility and elasticity. According to the results, the presence of BMI decreases distensibility percentage change level by 0.38 units (beta= - 0.38, 95% CI - 0.51;- 0.25,p < 0.001). The presence of fasting plasma glucose decreases elasticity percentage change level by 0.20 units. (beta= - 0.20, 95% CI - 0.39; - 0.01,p = 0.037). Conclusion Carotid artery distensibility and elasticity values increase after LSG, and this change could be caused by the change in metabolic parameters and heart geometry. These results may indirectly suggest that subclinical atherosclerosis in carotid arteries has decreased after obesity surgery.
