The relationship between dietary nut intake and hyperuricemia risk remains unclear. The aim of this study was to investigate the relationship between different nut intake and hyperuricemia risk with a cross-sectional study.

A semi-quantitative FFQ was adopted to collect dietary information. Biochemical and anthropometric parameters were measured by standard methods. Multivariate-adjusted logistic regression models were implemented to analyse the relationship between individual nut intake and hyperuricemia risk.

Qingdao University in Shandong Province, China.

During 2018–2019, a total of 14 056 undergraduates (6862 males and 7194 females) aged 15–25 years participated in the study.

After adjusting for multiple confounding factors, compared with the lowest quartile, the highest quartile intakes of pine nut (95 % CI (0·51, 0·98)) was significantly associated with 29 % reduction in hyperuricemia risk, the highest quartile intake of walnut (OR = 0·78; 95 % CI (0·58, 1·05)) was marginally negatively associated with hyperuricemia risk.

The present study showed that the relationships between intakes of different nuts and hyperuricemia risk were different. Increased dietary intakes of walnut and pine nut are negatively associated with the hyperuricemia.

Abdominal obesity was suggested to be a better predictor than Metabolic Syndrome (MetS) for cardiovascular mortality, however is has not been extensively studied in schizophrenia. Hyperuricemia (HU) was also suggested to be both an independent risk factor for greater somatic comorbidity and a global metabolic stress maker in patients with schizophrenia. The aim of this study was to estimate the prevalence of MetS, abdominal obesity and HU and to examine the association between metabolic parameters with HU in a cohort of French patients with schizophrenia or schizoaffective disorder (SZ), and to explore if patients were correctly treated.

In total, 240 SZ patients (age = 31.4 years, male gender 74.3%) were systematically included. Metabolic syndrome was defined according to the International Diabetes Federation and HU if serum uric acid level was above 360 μmol/L.

MetS, abdominal obesity and HU were found respectively in 24.2%, 21.3% and 19.6% of patients. In terms of risk factors, multiple logistic regression showed that after taking into account the potential confounders, the risk for HU was higher in males (OR = 5.9, IC 95 [1.7–21.4]) and with subjects with high waist circumference (OR = 3.1, IC 95 [1.1–8.3]) or hypertriglyceridemia (OR = 4.9, IC 95 [1.9–13]). No association with hypertension, low HDL cholesterol or high fasting glucose was observed. Only 10% of patients with hypertension received a specific treatment, 18% for high fasting glucose and 8% for dyslipidemia.

The prevalence of MetS, abdominal obesity and hyperuricemia is elevated in French patients with schizophrenia, all of which are considerably under-diagnosed and undertreated. HU is strongly associated with abdominal obesity but not with psychiatric symptomatology.

To investigate the association between the intake of selected food groups and beverages and serum uric acid (UA).

Cross-sectional study using the baseline data (2008–2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Food intake was assessed by food frequency questionnaire with 114 items. Linear and logistic regressions investigated the associations between the daily intake of each food group (servings/d) and UA (mg/dl) and hyperuricemia (UA ≥ 6·8 mg/dl), respectively. All the analyses were adjusted for potential confounders, energy intake and all food groups.

Teaching and research institutions from six Brazilians states.

The participants were 14 320 active and retired civil servants, aged 35–74 years.

Higher intake of dairy products was associated with lower serum UA levels in both sexes, with a statistical dose-response gradient. High meat intake was associated with high UA only in women, and high intake of organ meats, in men. Intake of fish and fruits, vegetables and legumes were not associated with serum UA. In men, moderate and high intake of alcoholic beverages, specifically beer and spirits, but not wine, increased UA. In women, only high intake of alcoholic beverages, specifically beer, was associated with increased serum UA. Similar associations were seen for hyperuricemia.

Results suggest a potential beneficial role of dairy products consumption on UA levels. The association between alcohol intake and UA differed according to type of beverage and between sexes. Results reinforce the need to consider the whole diet in the analysis and to conduct sex stratified analysis.

Limited data exist for management of hyperuricemia in non-oncologic patients, particularly in paediatric cardiac patients. Hyperuricemia is a risk factor for acute kidney injury and may prompt treatment in critically ill patients. The primary objective was to determine if rasburicase use was associated with greater probability normalisation of serum uric acid compared to allopurinol. Secondary outcomes included percent reduction in uric acid, changes in serum creatinine, and cost of therapy.

A single-centre retrospective chart review.

A 20-bed quaternary cardiovascular ICU in a university-based paediatric hospital in California.

Patients admitted to cardiovascular ICU who received rasburicase or intravenous allopurinol between 2015 and 2016.

None.

Data from a cohort of 14 patients receiving rasburicase were compared to 7 patients receiving IV allopurinol. Patients who were administered rasburicase for hyperuricemia were more likely to have a post-treatment uric acid level less than 8 mg/dl as compared to IV allopurinol (100 versus 43%; p = 0.0058). Patients who received rasburicase had a greater absolute reduction in post-treatment day 1 uric acid (−9 mg/dl versus −1.9 mg/dl; p = 0.002). There were no differences in post-treatment day 3 or day 7 serum creatinine or time to normalisation of serum creatinine. The cost of therapy normalised to a 20 kg patient was greater in the allopurinol group ($18,720 versus $1928; p = 0.001).

In a limited paediatric cardiac cohort, the use of rasburicase was associated with a greater reduction in uric acid levels and associated with a lower cost compared to IV allopurinol.
