OBJECTIVE To characterize the maximum P-wave duration (Pmax) and P-wave dispersion (PWD) according to blood pressure (BP) and uric acid (UA) levels in geriatric patients. METHOD An analytical study was performed in 83 patients aged over 60 years treated at the Family Medical Office 5 of the Aracelio Rodríguez Castellón Polyclinic, in Cienfuegos, Cuba between January and December 2015. The sam...

For the detection of metabolic disorders of uric acid in upper urolithiasis, an oral purine loading test was performed in 78 patients with calcium-containing calculi, 5 patients with uric acid calculi, and 34 stone free subjects. From the results of the normal subject group, the criteria of hyperuricemia, latent hyperuricemia, hyperuricosuria and latent hyperuricosuria were proposed. In calcium...

Uric acid is the product of purine metabolism and its increased levels result in hyperuricemia. A number of epidemiological reports link hyperuricemia with multiple disorders, such as kidney diseases, cardiovascular diseases and diabetes. Recent studies also showed that expression and functional changes of urate transporters are associated with hyperuricemia. Uric acid transporters are divided ...

OBJECTIVES The aim of this study was to examine the association between shift work and hyperuricemia among steel company workers. METHODS We examined 1,029 male workers at a Korean steel company between June 6 and June 28, 2013. We conducted anthropometric measurements, questionnaire surveys, and blood tests. Hyperuricemia was defined as a serum uric acid concentration of ≥7.0 mg/dL. Logistic...

OBJECTIVES Hyperuricemia provokes endothelial dysfunction (ECD). Decreased endothelial nitric oxide synthase (eNOS) activity is an important source of ECD. Cationic amino acid transporter-1 (CAT-1) is the specific arginine transporter for eNOS. We hypothesize that hyperuricemia inhibits arginine uptake. METHODS Experiments were performed in freshly harvested aortas from untreated animals and ...

BACKGROUND The prevalence of hyperuricemia varied in different populations and it appeared to be increasing in the past decades. Recent studies suggest that hyperuricemia is an independent risk factor for cardiovascular disease. However, there has not yet been a systematic analysis of the prevalence of hyperuricemia in China. METHODS Epidemiological investigations on hyperuricemia in China pu...

the goal of this study was to investigate the common clinical chemistry and distribution of xanthine oxidase (xo) in selected tissues of a mouse model of menopause. twenty four nmri female mice were divided into three groups: normal control (nc), and ovariectomized (ovx) groups and an estrogen-treated ovariectomized (ovx+e) group which received subcutaneous injection of estradiol benzoate (2 mg...

background: efficacy of rasburicase in pediatric patients with leukemia and lymphoma is proved. this study aims toweigh efficacy and safety of rasburicase versus more conventional therapy, allopurinol, and to compare their safetyand properties in tumor lysis syndrome (tls) of leukemia and lymphoma patients.materials and methods: the study was done with a retrospective cohort design. patients we...

Background: Hyperuricemia contributes to kidney injury, characterized by tubular injury with epithelial–mesenchymal transition (EMT). Wnt5a/Ror2 signaling drives EMT in many kidney pathologies. This study sought to evaluate the involvement of Wnt5a/Ror2 in hyperuricemia-induced EMT in kidney tubular injury.Methods: A hyperuricemia model was performed in male Swiss background mice (3 months old,...
