However, evidence of the association of vitamin E concentration in neural tissue with AD pathologies is limited. Design The cross-sectional relationship between the human brain concentrations of α- and γ-tocopherol and the severity of AD pathologies - neurofibrillary tangle (NFT) and neuritic plaque (NP) - was investigated. Setting & Participants Brains from 43 centenarians (≥ 98 years at death) enrolled in the Phase III of the Georgia Centenarian Study were collected at autopsy. Measurements Brain α- and γ-tocopherol concentrations (previously reported) were averaged from frontal, temporal, and occipital cortices. NP and NFT counts (previously reported) were assessed in frontal, temporal, parietal, entorhinal cortices, amygdala, hippocampus, and subiculum. NFT topological progression was assessed using Braak staging. Multiple linear regression was performed to assess the relationship between tocopherol concentrations and NP or NFT counts, with and without adjustment for covariates. Results Brain α-tocopherol concentrations were inversely associated with NFT but not NP counts in amygdala (β = -2.67, 95% CI [-4.57, -0.79]), entorhinal cortex (β = -2.01, 95% CI [-3.72, -0.30]), hippocampus (β = -2.23, 95% CI [-3.82, -0.64]), and subiculum (β = -2.52, 95% CI [-4.42, -0.62]) where NFT present earlier in its topological progression, but not in neocortices. Subjects with Braak III-IV had lower α-tocopherol (median = 69,622 pmol/g, IQR = 54,389-72,155 pmol/g) than those with Braak I-II (median = 72,108 pmol/g, IQR = 64,056-82,430 pmol/g), but the difference was of borderline significance (p = 0.063). γ-Tocopherol concentrations were not associated with either NFT or NP counts in any brain regions assessed. Conclusions Higher brain α-tocopherol level is specifically associated with lower NFT counts in brain structures affected in earlier Braak stages. Our findings emphasize the possible importance of α-tocopherol intervention timing in tauopathy progression and warrant future clinical trials.","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"10 ","pages":"8-16"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10002902/pdf/jarlife-10-008.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9120364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article highlights efforts to bridge the \"digital divide\" between generations and addresses the beneficial impact telemedicine has on older people's lifestyles. Novel triage models for accessing emergency care which were successful for patients of all age groups including those over 65 years are described. Moreover, innovative successful approaches to the outpatient assessment of older patients with complex chronic health conditions using telemedicine are highlighted. Furthermore, innovative solutions piloted in remote areas of Australia offer promise for telemedicine-lead remote assessment of older patients, and the results are encouraging compared to in-person consultations. The experience with a General Practitioner (GP)/specialist online real-time interaction model for remote management of HF in mainly older people has also been encouraging. The use of telemedicine in falls prevention has produced impressive results in high-risk older patients albeit with some ambivalence from older participants. Virtual reality rehabilitation programmes have produced better physical outcomes than traditional rehabilitation programmes. Furthermore, telerehabilitation for chronic obstructive pulmonary disease (COPD) and HF have shown to be both feasible and effective. To maximise their benefits in the difficult post-COVID-19 period, technologies must be embraced by both physicians and older patients. Online community care platforms discussed have demonstrated a positive, tangible impact on the lifestyle of the older generation. Furthermore, educational guidelines can assist in implementing the fundamentals of telemedicine, but for the widespread successful and safe integration of these services, adoption of regulatory frameworks with a focus on ethical issues of telehealth is imperative.</p>","PeriodicalId":73537,"journal":{"name":"JAR life","volume":"9 ","pages":"35-39"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10002893/pdf/jarlife-9-035.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9119882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
