BACKGROUND: Cognitive impairment induced by cerebral infarction has become a devastating health problem. More efficient predictors are required to evaluate the potential cognitive decline after cerebral infarction in clinic. Serum uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) are two factors reported to correlate with cognitive impairment. However, the understanding on serum UA and hs-CRP with cognitive dysfunction remains unclear. METHODS: Serum UA and hs-CRP were evaluated in patients with cerebral infarction (n = 197) using single factor analysis and multivariate logistic regression analysis...

BACKGROUND: Evidence has shown that serum uric acid (UA) is associated with cognitive function, but this finding remains debatable. Serum UA is commonly elevated in patients with chronic heart failure (CHF), especially in men. However, the relationship between serum UA and cognitive function in CHF populations and stratified by sex are unclear. We aimed to examine whether serum UA was independently associated with cognitive function in CHF populations after controlling for demographic, medical and psychological variables and whether there was a sex difference in the association between serum UA and cognitive function among male and female CHF patients...

Background: Despite known associations of lower serum uric acid (UA) with Alzheimer's disease (AD) dementia or AD-related cognitive impairment, little is known regarding the underlying patho-mechanisms. We aimed to examine the relationships of serum UA with in vivo AD pathologies including cerebral beta-amyloid (Aβ) and tau deposition, AD-signature region cerebral glucose metabolism (AD-CM), and white matter hyperintensities (WMH). We also investigated the association between serum UA and cognitive performance, and then assessed whether such an association is mediated by the brain pathologies...

Introduction: Significance of serum uric acid (UA) in cerebrovascular disease still remains controversial. UA is most abundant natural antioxidant in human plasma. Its antioxidant properties might protect against free radical damage, thereby reducing the risk of oxidative stress-related cognitive impairment and dementia. Aim: In our investigation, we determine the level of UA in 100 male patients diagnosed with the first ischemic brain stroke (blood samples were collected during the acute phase and post-acute phase), 100 male patients diagnosed with vascular dementia and 100 male healthy volunteers (control group)...

A relationship between dysbiotic gut microbiome and chronic kidney disease (CKD) has been recently documented; it contributes to CKD-related complications, including cardiovascular disease. Aim: We tested how a low-protein diet (LPD)-with or without oral inulin supplementation as a prebiotic-modulates some inflammatory, atherosclerosis and endothelial dysfunction indices and nutritional markers, as well as psychocognitive functions in CKD patients. We conducted a prospective, case-control study on CKD patients on conservative therapy, divided in two groups: the intervention group treated with LPD (0...

Post-stroke cognitive impairment (PSCI) is a severe complication of stroke. Predicting PSCI is difficult because some risk factors for stroke, such as blood glucose level and blood pressure, are affected by many other elements. Although recent studies have shown that high serum uric acid (UA) levels are associated with cognitive dysfunction and may be a risk factor for PSCI, its impact remains unclear. Accordingly, the present study aimed to explore the association between serum UA level and PSCI. In total, 274 patients who experienced acute cerebral infarction, confirmed between January 2016 and December 2018, were enrolled...

BACKGROUND: It has been suggested that oxidative stress may have a role in the pathogenesis of Alzheimer's disease (AD). Serum uric acid (UA) could exert neuroprotective effects via its antioxidant capacities. Many studies investigated serum UA levels in subjects with AD, but to date, results are conflicting and evidence in old age subjects is weak. AIMS: In this study, we assess whether serum UA levels would be altered in the AD old age subjects compared to those of initial cognitive impairment and healthy controls...
