Materials and methods Epidemiological, clinical features, laboratory findings and radiological characteristics of 1563 hospitalised patients with COVID-19 in Ankara were collected, reviewed and analysed in this study. The risk factors associated with disease severity were investigated. Results Non-severe (1214; 77.7%) and severe cases (349; 22.3%) were enrolled in the study. Compared with the non-severe group, the severe group were significantly older and had more comorbidities (ie, hypertension, diabetes mellitus, cardiovascular disease and chronic kidney disease). Smoking was more common in the severe group. Severe patients had higher respiratory rates and higher incidences of cough and dyspnoea compared with non-severe patients. Compared with the non-severe patients, the severe patients had increased C-reactive protein (CRP), procalcitonin, neutrophil to lymphocyte ratio (NLR) and CRP/albumin ratio and decreased albumin. The occurrence rates of consolidation, subpleural sparing, crazy-paving pattern, cavity, halo sign, reversed halo sign, air bronchogram, pleural thickening, micronodule, subpleural curvilinear line and multilobar and bilateral involvement in the CT finding of the severe patients were significantly higher than those of the non-severe patients. Conclusions Many factors are related to the severity of COVID-19, which can help clinicians judge the severity of the patient and evaluate the prognosis. This cohort study revealed that male sex, age (>= 55 years), patients with any comorbidities, especially those with cardiovascular disease, dyspnoea, increased CRP, D-dimer and NLR, and decreased lymphocyte count and CT findings of consolidation and multilobar involvement were predictors of severe COVID-19.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.

However, published data are conflictive in this regard. Methods We investigated differences in clinical and management variables between male and female patients from the ATA study, a prospective, multicentre, observational study that included 1462 outpatients with chronic HFrEF between January and June 2019. Results Study population was predominantly male (70.1%). In comparison to men, women with chronic HFrEF were older (66 +/- 11 years vs 69 +/- 12 years, P < .001), suffered more hospitalisations and presented more frequently with NYHA class III or IV symptoms. Ischaemic heart disease was more frequent in men, whereas anaemia, thyroid disease and depression were more frequent in women. No difference was seen between genders in the use rate of renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or ivabradine, or in the proportion of patients achieving target doses of these drugs. Regarding device therapies, men were more often treated with an implantable cardioverter-defibrillator (ICD) and women received more cardiac resynchronisation therapy. Conclusion In summary, although management seemed to be equivalent between genders, women tended to present with more symptoms, require hospitalisation more frequently and have different comorbidities than men. These results highlight the importance of gender-related differences in HFrEF and call for further research to clarify the causes of these disparities. Gender-specific recommendations should be included in future guidelines in HFrEF.
