Item Dietary Fiber Intake: Its Relation With Glycation End Products and Arterial Stiffness in End-Stage Renal Disease Patients(2019) Demirci, Bahar Gurlek; Tutal, Emre; Eminsoy, Irem O.; Kulah, Eyup; Sezer, Siren; 30314838; AAB-3881-2021Objective: We aimed to analyze the relationship between the effect of total dietary fiber intake on C-reactive protein (CRP) and on oxidative stress parameters such as serum advanced glycation end products (AGEs), superoxide dysmutase (SOD), malondialdehyde, and arterial stiffness by pulse wave velocity (PWv) in maintanace hemodialysis (MHD) patients. Methods: Among 650 MHD patients, 128 were selected according to inclusion criteria. The dietary survey was performed with a 3-day dietary history. Dietary fiber level was adjusted for total energy intake by the residual method. Patients were stratified by quartiles of adjusted dietary fiber (ADF) level as group 1 (n = 32) (ADF: <8.86 g/day), group 2 (n = 35) (ADF: 8.86-12.50 g/day), group 3 (n = 31) (ADF: 12.51-15.90 g/day), and group 4 (n = 30) (ADF: >= 15.91 g/day). Monthly assessed biochemical parameters including serum hemoglobin, albumin, CRP, calcium, phosphorus, and lipid profile levels were recorded. Serum AGEs, SOD, and malondialdehyde levels were determined by ELISA method. The PWv was determined from pressure tracing over carotid and femoral arteries. Results: Patients in group 3 and 4 had significantly lower CRP and AGE than those in group 1 and 2. Mean serum SOD level and PWv were significantly higher in group 4. In regression analysis, ADF intake was the unique predictor for both AGE (r(2) = 0.164, P = 0.017) and CRP levels (r(2) = 0.238, P = 0.01). Conclusion: Present data show that dietary fiber intake is independently correlated with inflammation and oxidative stress. In addition, decreased fiber intake results in impaired arterial stiffness. Thus, adequate fiber intake could prevent cardiovascular events and inflammatory processes in patients undergoing MHD. (C) 2018 by the National Kidney Foundation, Inc.

Methods: Two hundred fifty-two postmenopausal female outpatients who were admitted to the obstetrics and gynecology and physical therapy clinics between July 2016 and December 2017 were retrospectively analyzed. The patients were grouped in relation to their T-score (normal [n=92], osteopenia [n=112], and PMO [n=48]). The serum levels of P/L, N/L, Vit-D, BMD and complete blood count of the patients were retrospectively examined. Results: The median P/L was significantly higher and Vit-D levels were significantly lower in the PMO group (130.75 [52.89-385] versus 123.05 [54-232.5], p=0.02 and 15.4 [4-34] versus 20.1 [4-47], p=0.003). While BMD and P/L were negatively correlated, a positive correlation between BMD and Vit-D was found. Vitamin D levels were negatively correlated with P/L (p<0.001) and N/L (p=0.04). Older age (>= 65 years), Vit-D deficiency and P/L values >125.06 were found as independent prognostic factors for PMO in regression analysis. Conclusion: Higher P/L seems to be a quite simple marker to help predict postmenopausal PMO. As seen in our study, having low levels of Vit-D is crucial for PMO.Item Aortic Stiffness and Inflammation: Dyslipidemia or Matrix Metalloproteinases?(2016) Tekin, Abdullah; 0000-0002-5658-870X; 27504843; ABD-7304-2021
