Uric acid and cardiovascular disease

Publication date: September 2018Source: Clinica Chimica Acta, Volume 484Author(s): Gjin NdrepepaAbstractUric acid (UA) is an end product of purine metabolism in humans and great apes. UA acts as an antioxidant and it accounts for 50% of the total antioxidant capacity of biological fluids in humans. When present in cytoplasm of the cells or in acidic/hydrophobic milieu in atherosclerotic plaques, UA converts into a pro-oxidant agent and promotes oxidative stress and through this mechanism participates in the pathophysiology of human disease including cardiovascular disease (CVD). Most epidemiological studies but not all of them suggested the existence of an association between elevated serum UA level and CVD, including coronary heart disease (CHD), stroke, congestive heart failure, arterial hypertension and atrial fibrillation as well as an increased risk for mortality due to CVD in general population and subjects with confirmed CHD. Evidence available also suggests an association between elevated UA and traditional cardiovascular risk factors, metabolic syndrome, insulin resistance, obesity, non-alcoholic fatty liver disease and chronic kidney disease. Experimental and clinical studies have evidenced several mechanisms through which elevated UA level exerts deleterious effects on cardiovascular health including increased oxidative stress, reduced availability of nitric oxide and endothelial dysfunction, promotion of local and systemic inflammation, vasoconstriction and prolif...

In this study, we examined the effect of laparoscopic-guided transversus abdominis plane block (LG TAP) for further optimizing multimodal pain control.MethodsThis is a retrospective analysis of a prospectively collected database of 140 consecutive patients undergoing LSG without TAP block (pre-TAP group) compared to 131 patients undergoing LSG with LGTAP (TAP group). All operations were performed laparoscopically utilizing uniform clinical pathways. Baseline characteristics for both groups were comparable. Both groups received standardized anesthesia. Outcomes included time to postoperative ambulation, pain scores, PCA vol...

ConclusionsThis is the first report of cognitive improvements following VSG and the first direct comparison of cognitive improvements following RYGB and VSG. Short-term improvements in specific domains of cognitive function are observed at the beginning of the active weight loss phase following bariatric surgery that persisted to 3  months. The anatomical distinction between the two surgeries and resulting differential metabolic profiles may be responsible for the improvements in attention observed following RYGB but not following VSG.

This study aims to assess the referral and practice patterns of PCPs treating patients with obesity. Our goal is to understand treatment barriers in order to implement targeted interventions that enhance quality of care.MethodsA 39-question electronic survey was emailed to PCPs at a single academic institution with community physicians. Questions explored providers ’ demographics, referral patterns, and knowledge of pathophysiologic obesity mechanisms and bariatric surgery qualifications. Frequency and univariate analyses were performed and compared providers’ demographics, positions, and BMIs between referring...

Authors: Matsumura E, Nohara K, Tanaka N, Fujii N, Sakai T Abstract Polypharmacy in elderly persons living at home or in a nursing home is an issue. In the field of dentistry, strategies to reduce polypharmacy must be promoted; however, there is insufficient basic data on medications received by elderly persons with dysphagia living at home or in a nursing home. The subjects were 106 elderly persons with dysphagia living at home or in a nursing home. Based on their medical records, the presence of disease and number/type of drugs being administered were investigated. Stroke, dementia, and hypertension were common. ...
