Intrarenal Angiotensin-II (AngII) and activation of the NF-κB and NLRP3 inflammasome pathways exert a relevant pathogenic role in the progression of chronic kidney disease (CKD). We sought to investigate whether monotherapy with Losartan and combined treatment with Losartan and the NF-κB inhibitor pyrrolidine dithiocarbamate (PDTC) would attenuate experimental aging nephropathy. Materials and Methods Forty adult Male Munich-Wistar rats were distributed among four groups: 12M (n=10), untreated 12-month-old rats; 15M (n=10), untreated 15-month-old rats; 15MLos (n=8), rats receiving Losartan (50 mg/kg/d) and 15MLos+PDTC (n=8), rats receiving Losartan and PDTC (60 mg/kg/d). All treatments were given by mouth from 12 to 15 months of age. Results Group 15M exhibited slightly decreased tail-cuff pressure, and marked increase in albuminuria, sclerotic glomeruli, cortical collagen-1 deposition and infiltration by myofibroblasts, AngII-positive cells and proinflammatory M1 macrophages, whereas the amount of anti-inflammatory M2 macrophages was reduced. In addition, the renal abundance of TLR4, nuclear p65 and IL-6 was increased, indicating activation of the NF-κB pathway, without evidence of simultaneous activation of the NLRP3 cascade. Losartan treatment decreased cortical collagen-1 deposition, myofibroblasts and AngII-positive cells, and partially restored renal M2, but had no significant effect on albuminuria, glomerulosclerosis or NF-κB activation.

We examined prevalence of age-related hearing loss (ARHL) in healthy, community-dwelling older adults, and determined whether sociodemographic, lifestyle or health factors associate with hearing thresholds. Audiometry assessment was investigated with self-reports of hearing loss and hearing handicap. Methods Australian participants (n=1260) of median age 73 years (IQR 71-76) joined ASPREE-Hearing, a sub-study of the ASPREE (ASPirin in Reducing Events in the Elderly) trial with exclusions including cognitive impairment, cardiovascular disease (CVD), independence-limiting physical disability, and uncontrolled hypertension. ASPREE collected demographics, anthropometrics, lifestyle, and health data. Audiometry measured better ear pure-tone-average (PTA) across four frequencies (0.5-4kHz) to establish hearing thresholds, categorised as normal or mild, moderate and severe hearing loss. Questionnaires collected perceived hearing problems and noise exposure. Results ARHL prevalence by audiometry was 49.7%, affecting men (59%) more than women (41%). A majority (54.5%) self-reported some hearing problems which mostly aligned with objective assessments; 45.6% self-reported a \"little trouble\" with hearing, while 35% had objective mild hearing loss; (8.3%) reported having a \"lot of trouble\" hearing while 13% had moderate hearing loss; and (0.6%) reported being \"deaf\" with 2% demonstrated severe hearing loss. There was a significant association (p<0.001) between self-reported hearing handicap and audiometric measures of hearing loss. In multivariate analysis of health, demographics and lifestyle risk factors only age, gender (men), and education years (<12) remained associated (P<0.05) with hearing loss. Hearing thresholds were not associated with smoking, living situation, alcohol use, hypertension, diabetes, or chronic kidney disease. Conclusion ARHL robustly assessed by audiometry is common among healthy older Australians with men more likely to have abnormal hearing thresholds than women. Hearing loss was associated with fewer years of formal education, but not with a range of chronic conditions or alcohol use. Self-reported hearing loss correlates well with higher PTA hearing threshold levels in this healthy cohort where prevalence was lower than previously reported for the age group >70 years. Hearing health education remains an important public health tool for this age. Targeting hearing in older patient health checks could be beneficial to mitigate the cognitive, social, and mental health consequences of ARHL, even if patients do not report a problem or handicap.</p>","PeriodicalId":12662,"journal":{"name":"Gerontology","volume":" ","pages":"1-19"},"PeriodicalIF":3.1,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142686792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
