Body sites such as the skin, the gut and the mouth support communities of microorganisms (collectively known as the microbiome) that are both numerous and diverse. As our understanding of the microbiome advances, it is evident that these microbial populations participate in a multitude of symbiotic associations with us. The disruption of these associations can lead to a range of diseases beyond mere pathogenesis as microbial nutrition, signaling, and immune defense break down. It is known that changes in microbial composition occur as the human host ages and that diet and living conditions influence the microbiome of older individuals. However, the link between the microbiome and frailty is as yet mostly unexplored. Although the microbiome is likely to influence health factors that contribute to frailty, further work is needed to determine whether overall microbial signatures of frailty exist and, if so, what the diagnostic and therapeutic utility of these signatures might be.</p>","PeriodicalId":37866,"journal":{"name":"Interdisciplinary topics in gerontology and geriatrics","volume":"41 ","pages":"54-65"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000381162","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34117506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scientific literature on the behavioral health of OALH is highly underdeveloped, especially in terms of the creation of empirically supported interventions to alleviate psychological distress. From the literature that does exist, there are a number of salient factors that emerge, including stereotypes (i.e., older adults are not sexually active), stigmatization (of those who are HIV-positive), social isolation, unique psychosocial needs for newly-infected OALH, and elevated rates of emotional distress and concomitant disorders - especially, depression. These factors persist alongside findings that OALH have fewer sources of social or institutional support, fewer surviving peers, and a lack of family to care for them. Additionally, many OALH report problems with substance use, both as a function of their 'baby-boomer' generational status (i.e., people born between 1946 and 1964) and in terms of the life experiences associated with their HIV-positive status. Overall, it is unclear how mental health and substance use problems affect combination antiretroviral therapy adherence, multimorbidity, polypharmacy, or treatment outcomes in this population, and further study is needed.","PeriodicalId":37866,"journal":{"name":"Interdisciplinary topics in gerontology and geriatrics","volume":"448 1","pages":"85-100"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82910139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
