Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p = 0.04, OR = 1.74, 95% CI: 1.0 1-3.00). The presence of MtS had significant correlation with kidney stone (p = 0.01, OR = 1.83, 95% CI: 1.1 4-2.93), which were associated with the increment of MtS components (p < 0.01). After adjusting for age and testosterone level, abnormal blood pressure (BP) was the most significantly independent component of MtS for kidney stone among the MtS components (p < 0.01, OR = 2.81, 95% CI: 1.46-5.39).Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone. [ABSTRACT FROM AUTHOR]

This study aims to analyze the effects of climate parameters on the number of urolithiasis treatments in our hospital and understand the effects of climate parameters on the prevalence of urolithiasis in southern Taiwan. We also look at trends associated with urolithiasis and treatments. Retrospectively reviewed the records of extracorporeal shockwave lithotripsy (ESWL), ureteroscopy (URS), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PCNL) performed in our hospital from January 2012 to December 2018. Climate data for were collected from Central Weather Bureau. The monthly meteorological data included average temperatures, humidity, rainfall, sunshine hours, atmospheric pressure, and wind speed. Monthly numbers of patients undergoing stone management was positively correlated to average temperature (r = 0.657), relative humidity (r = 0.234), monthly rainfall (r = 0.261) and monthly sunshine hours (r = 0.348), while it was negatively correlated to atmospheric pressure (r = - 0.522). The multivariate linear regression model demonstrated temperature (ß = 10.682, 95% CI 6.178-14.646, p < 0.001) and Relative humidity (ß = - 95% CI - 5.233- - 1.216, p = 0.002) to be independently related to numbers of stone treatment. The data also revealed a rising prevalence of urolithiasis with an associated increase in the number of interventions, with fewer ESWL (74.0-49.4%). Temperature and relative humidity are associated with monthly numbers of stone treatment. Ambient temperature is the most critical climate factor affecting the prevalence of symptomatic urolithiasis and intention of active stone removal in southern Taiwan., (© 2023.

Background: Hepatocyte nuclear factor-4α (HNF4A) can influence the risk of insulin resistance that is postulated to be an important link between metabolic syndrome (MetS) and testosterone deficiency (TD) in men., Aim: To investigate the relationship between single-nucleotide polymorphisms (SNPs) of HNF4A and the risk of developing MetS and TD in a population of aging Taiwanese men., Methods: A free health screening of men over 40 years of age was conducted in a medical center in Kaohsiung City, Taiwan. All participants underwent a physical examination, answered a questionnaire on demographics and medical history, completed the Androgen Deficiency in The Aging Male questionnaire to assess clinical symptoms of TD, and provided 20-mL whole blood samples for biochemical, hormonal, and genetic evaluation., Main Outcome Measure: 3 common SNPs (rs11574736, rs1884613, and rs2144908) of HNF4A were selected and identified using a TaqMan 5' allelic discrimination assay., Results: 559 men were enrolled for this study (mean age, 55.8± 4.9 years). Prevalence of TD was significantly higher (P = .031) in subjects with MetS (16.8%) than those without MetS (10.1%). In SNP rs1884613 of HNF4A, subjects with the C allele carried a 1.31- and 1.50-times higher risk of developing MetS and TD, respectively, compared to those with the G allele, after adjusting for potential covariates. In addition, subjects with the CC genotype were exposed to a 1.91- and 2.20-times higher risk of developing MetS and TD, respectively, compared to those with the GG genotype., Clinical Implications: Our findings may point to the importance of the role played by insulin resistance in the link between MetS and TD., Strength & Limitations: Our current work is the first report with adequate sample size to evaluate the role of genetic variants of HNF4A on the risk of both MetS and TD in men. The limitations included subjects enrolled from a free health screening and single measurement of serum testosterone levels., Conclusion: The rs1884613 SNP marker of HNF4A is significantly associated with an increased risk for developing both MetS and TD in aging Taiwanese men. Further population-based studies utilizing larger samples of different ethnicities may be needed to confirm these preliminary results. Liu C-C, Lee Y-C, Hung S-P.
