Frailty and brain changes in older adults without cognitive impairment: A scoping review.

Little is known about changes in the brain associated with frailty, in particular, which brain areas could be related to frailty in older people without cognitive impairment. This scoping review mapped evidence on functional and/or structural brain changes in frail older adults without cognitive impairment. The methodology proposed by the JBI® was used in this study. The search in PubMed, PubMed PMC, BVS/BIREME, EBSCOHOST, Scopus, Web of Science, Embase, and PROQUEST was conducted up to January 2023. Studies included following the population, concepts, context and the screening and data extraction were performed by two independent reviewers. A total of 9,912 records were identified, 5,676 were duplicates and were excluded. The remaining articles were screened; 31 were read in full and 17 articles were included. The results showed that lesions in white matter hyperintensities, reduced volume of the hippocampus, cerebellum, middle frontal gyrus, low gray matter volume, cortical atrophy, decreased connectivity of the supplementary motor area, presence of amyloid-beta peptide (aß) in the anterior and posterior putamen and precuneus regions were more frequently observed in frail older adults, compared with non-frail individuals. Studies have suggested that such findings may be of neurodegenerative or cerebrovascular origin. The identification of these brain alterations in frail older adults through neuroimaging studies contributes to our understanding of the underlying mechanisms of frailty. Such findings may have implications for the early detection of frailty and implementation of intervention strategies.

Cognitive impairment in post-acute COVID-19 syndrome: a scoping review / Comprometimento cognitivo na síndrome pós-COVID-19 aguda: uma revisão de escopo

Abstract Emerging studies indicate the persistence of symptoms beyond the acute phase of COVID-19. Cognitive impairment has been observed in certain individuals for months following infection. Currently, there is limited knowledge about the specific cognitive domains that undergo alterations during the post-acute COVID-19 syndrome and the potential impact of disease severity on cognition. The aim of this review is to examine studies that have reported cognitive impairment in post-acute COVID-19, categorizing them into subacute and chronic phases. The methodology proposed by JBI was followed in this study. The included studies were published between December 2019 and December 2022. The search was conducted in PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo, and EBSCOHost. Data extraction included specific details about the population, concepts, context, and key findings or recommendations relevant to the review objectives. A total of 7,540 records were identified and examined, and 47 articles were included. The cognitive domains most frequently reported as altered 4 to 12 weeks after acute COVID-19 were language, episodic memory, and executive function, and after 12 weeks, the domains most affected were attention, episodic memory, and executive function. The results of this scoping review highlight that adults with post-acute COVID-19 syndrome may have impairment in specific cognitive domains.

Resumo Estudos emergentes indicam a persistência dos sintomas além da fase aguda da COVID-19. O comprometimento cognitivo foi observado em alguns indivíduos durante meses após a infecção. Atualmente, há pouco conhecimento sobre os domínios cognitivos específicos que sofrem alterações durante a síndrome pós-aguda da COVID-19 e o possível impacto da gravidade da doença na cognição. O objetivo desta revisão é examinar estudos que relataram comprometimento cognitivo na COVID-19 pós-aguda, categorizando-os em fases subaguda e crônica. A metodologia proposta pela Joanna Briggs Institute foi seguida neste estudo. Os estudos incluídos foram publicados entre dezembro de 2019 e dezembro de 2022. A busca foi realizada no PubMed, PubMed PMC, BVS - BIREME, Embase, SCOPUS, Cochrane, Web of Science, Proquest, PsycInfo e EBSCOHost. A extração de dados incluiu detalhes específicos sobre a população, os conceitos, o contexto e as principais descobertas ou recomendações relevantes para os objetivos da revisão. Um total de 7.540 registros foi identificado e examinado, e 47 artigos foram incluídos. Os domínios cognitivos mais frequentemente relatados como alterados de 4 a 12 semanas após a COVID-19 aguda foram linguagem, memória episódica e função executiva e, após 12 semanas, os domínios mais afetados foram atenção, memória episódica e função executiva. Os resultados dessa revisão de escopo destacam que adultos com síndrome pós-aguda da COVID-19 podem apresentar comprometimento em domínios cognitivos específicos.

Cognitive Impairment Predicts Sarcopenia 9 Years Later among Older Adults.

OBJECTIVE: To assess the longitudinal association between cognitive impairment and sarcopenia in a sample of Brazilian community-dwelling older adults. DESIGN: Nine-year observational prospective study. SETTING AND PARTICIPANTS: A total of 521 community-dwelling older adults from 2 Brazilian sites of the Frailty in Brazilian Older Adults (FIBRA in Portuguese) study. METHODS: Sarcopenia was defined as low hand-grip strength and low muscle mass. Cognitive impairment was determined at baseline using the Mini-Mental State Examination, with education-adjusted cutoff scores. The logistic regression model was used to assess the association between cognitive impairment and incident sarcopenia after adjusting for gender, age, education, morbidities, physical activity, and body mass index. Inverse probability weighting was applied to correct for sample loss at follow-up. RESULTS: The mean age of the study population was 72.7 (±5.6) years, and 365 were women (70.1%). Being 80 years and older [odds ratio (OR), 4.62; 95% CI, 1.38-15.48; P = .013], being under- and overweight (OR, 0.29; 95% CI, 0.11-0.76; P = .012, and OR, 5.12; 95% CI, 2.18-12.01; P < .001, respectively) and having cognitive impairment (OR, 2.44; 95% CI, 1.18-5.04; P = .016) at baseline predicted sarcopenia after 9 years. CONCLUSION AND IMPLICATIONS: Cognitive impairment may predict sarcopenia in Brazilian older adults. More studies are necessary to identify the main mechanisms shared by sarcopenia and cognitive decline, which could support the development of prevention interventions.

A look at vulnerability in the older population in health sciences studies: a systematic review / O olhar sobre a vulnerabilidade na população idosa nos estudos das ciências da saúde: uma revisão sistemática

The objective of this study was to systematically investigate and review studies on the concept of vulnerability associated with the health of the older population. Articles were selected, filtered, and analyzed following the steps recommended by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Screening and data extraction were performed independently by 2 reviewers using templates developed by the authors. Data extracted included specific details about population, interest, and context. Studies were eligible for inclusion if they: 1) were cross-sectional or prospective, 2) involved community-dwellers aged ≥ 60 years, 3) were published in the last 10 years, and 4) had as a concept vulnerability associated with the health of the older population. A total of 833 studies were identified and screened, 26 of which were included. Most included studies addressed vulnerability in older adults as an individual aspect, whether biological or psychological. The remaining studies reported vulnerability as affecting socio-environmental, health care system, and multifactorial aspects. Therefore, the concept of "vulnerability in older people" was not properly defined in the biomedical scientific community. When we return to the guiding question of this review, we can conclude that the conditions of vulnerability of older people are being treated broadly and diversely, producing different methodological strategies. The systematic review was conducted in the United States National Library of Medicine (PubMed), Latin American and Caribbean Health Sciences Literature (LILACS), and Scientific Electronic Library Online (SciELO) databases between August and December 2020 and updated in September 2022, with registration number CRD42022361649

O objetivo da pesquisa é investigar e revisar sistematicamente estudos sobre o conceito de vulnerabilidade associado à saúde da população idosa. Os trabalhos foram selecionados, filtrados e analisados seguindo as etapas recomendadas pela The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. A triagem e a extração de dados foram realizadas por dois revisores independentes usando modelos desenvolvidos pelos autores. A extração de dados incluiu detalhes específicos da população; interesse; contexto. Consideraram-se artigos que: 1) fossem estudos transversais ou prospectivos, 2) envolvessem idosos da comunidade (≥ 60 anos), 3) fossem dos últimos dez anos; tivessem como conceito a vulnerabilidade associada à saúde da população idosa. O total de 833 estudos foi identificado e triado, e 26 deles foram incluídos. A maioria dos estudos incluídos verificou a vulnerabilidade do idoso no aspecto individual, seja biológico, seja psicológico. Em contrapartida, o restante dos estudos acredita que a vulnerabilidade atinja o aspecto socioambiental, sistema de saúde e multifatorial. Sendo assim, conceito de "vulnerabilidade do idoso" não está devidamente definido na comunidade científica biomédica. Neste caso, retornando à questão norteadora desta revisão, conclui-se que as condições de vulnerabilidade do idoso estão sendo tratadas de maneira ampla e diversa, produzindo diferentes estratégias metodológicas. A revisão sistemática foi realizada nas bases de dados United States National Library of Medicine (PubMed), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) e Scientific Electronic Library Online (SciELO), entre agosto e dezembro de 2020, com atualização em setembro de 2022, sob código CRD42022361649

Relationship between self-reported health and neuroticism in older adults: a scoping review / Relação entre saúde autorreferida e neuroticismo em idosos: uma revisão de escopo

This scoping review aims to identify and map the existing literature regarding the relationship between neuroticism and self-reported health in community-dwelling older adults. We adopted the Joanna Briggs Institute Manual for Evidence Synthesis recommendations and followed the PRISMA-SCr when reporting it. The search was performed on ten different databases, including: Cumulative Index to Nursing and Allied Health Literature, Cochrane, Embase, PsycArticles, PsycInfo, United States National Library of Medicine, Scopus, Web of Science, Ageline and Biblioteca Virtual em Saúde/Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde databases until February 2021. Data screening and extraction were performed by two independent reviewers. We included primary studies with older adults (≥60 years) [participants] that adopted validated instruments to assess neuroticism and self-reported health [concept] in the community [context], published in Portuguese, English, or Spanish. We identified 3453 articles and included 15 studies in this review. We extracted the main categories of included studies, characteristics of the participants, methodological issues, and biopsychosocial factors. Outcomes were reported in three sections: Focus of studies; Definitions and measures of neuroticism and self-reported health; Associations with biopsychosocial factors. We found an association between high neuroticism and poor self-reported health. Some biopsychosocial factors may influence this relationship, such as chronic diseases, depression, social support, and a sense of control, which must be considered in future studies to shed light on this topic

Esta revisão de escopo tem como objetivo identificar e mapear a literatura existente sobre a relação entre neuroticismo e saúde autorreferida em idosos vivendo na comunidade. Adotamos as recomendações do Joanna Briggs Institute Manual for Evidence Synthesis e seguimos o PRISMA-SCr ao reportá-lo. A busca foi realizada em dez bases de dados diferentes, incluindo: Cumulative Index to Nursing and Allied Health Literature, Cochrane, Embase, PsycArticles, PsycInfo, United States National Library of Medicine, Scopus, Web of Science, Ageline e Biblioteca Virtual em Saúde/Centro Latino -Americano e do Caribe de Informação em Ciências da Saúde até fevereiro de 2021. A triagem e extração dos dados foram realizadas por dois revisores independentes. Incluímos estudos primários com idosos (≥60 anos) [participantes] que adotaram instrumentos validados para avaliar neuroticismo e saúde autorreferida [conceito] na comunidade [contexto], publicados em português, inglês ou espanhol. Identificamos 3.453 artigos e incluímos 15 estudos nesta revisão. Extraímos as principais categorias dos estudos incluídos, características dos participantes, questões metodológicas e fatores biopsicossociais. Os resultados foram relatados em três seções: Foco dos estudos; Definições e medidas de neuroticismo e autoavaliação de saúde; Associações com fatores biopsicossociais. Encontramos uma associação entre alto neuroticismo e má saúde autorrelatada. Alguns fatores biopsicossociais podem influenciar nessa relação, como doenças crônicas, depressão, suporte social e senso de controle, que devem ser considerados em estudos futuros para elucidar esse tema

Factors related to malnutrition and their association with frailty in community-dwelling older adults registered at a geriatric clinic.

BACKGROUND: We hypothesized that factors related to malnutrition, namely low muscle mass, appetite loss, and adiposity, are associated with frailty and pre-frailty in community-dwelling older adults. AIMS: To identify the prevalence of frailty and pre-frailty in a Brazilian convenience sample and test the association between these conditions and malnutrition-related factors. METHODS: This is a cross-sectional analysis of an ongoing community project. We studied 106 older adults (≥60 years old). Frailty (dependent variable) was screened using the FRAIL-BR scale. The independent variables were appetite loss (AL), screened from the SNAQ questionnaire; sarcopenia risk, investigated by SARC-F; body adiposity, estimated by the body mass index (BMI); visceral adiposity, estimated by waist circumference (WC) and the combination of these two indicators. The associations were investigated using multinomial logistic regression models. MAIN RESULTS: We found, from our sample, 30.2 % pre-frail and 31.1 % frail participants. The frail and pre-frail were older than the non-frail; the frail ones presented a higher proportion of sarcopenia risk and a higher proportion of AL. From the multiple regression models, frailty conditions showed significant association with the AL (OR = 0.68; p = 0.012 and OR = 0.64; p = 0.009 for pre-frail and frail, respectively) and with sarcopenia risk (OR = 3.24; p = 0.001 and OR = 5.34; p < 0.011 for pre-frail and frail respectively). The adiposity indicated by waist circumference, and age, remained in the final model only as adjusting variables but without statistical significance. CONCLUSIONS: in our convenience sample of older adults, frailty and pre-frailty showed significant association with appetite loss and sarcopenia risk, but not with adiposity indicators. Future studies are needed to better understand our findings.

The association between appetite loss, frailty, and psychosocial factors in community-dwelling older adults adults.

BACKGROUND: Appetite loss (AL) in older adults can reduce energy and nutrient intake, increasing the risk of weight loss, sarcopenia, frailty, and ultimately, mortality. The identification of associated factors to AL is important to plan different interventions. AIMS: To identify the association between appetite loss, frailty, and psychosocial factors in community-dwelling older adults. METHODS: Cross-sectional analysis of the cohort study MiMiCS-FRAIL based in Jundiai City, São Paulo, Brazil. Patients 60+ years old were evaluated from January 2019 to August 2020. The AL (dependent variable) was evaluated through the SNAQ questionnaire; the independent variables were: frailty (identified by frailty index-36; FI-36) which is based on the accumulation of deficits; depressive symptoms (GDS scale); ethnicity, and years of formal schooling, both used as proxies of socioeconomic status. The associations were investigated using logistic regression models (crude and multiple). MAIN RESULTS: The final sample included 122 older adults, 58.2% of women, mean age of 71.7 years, 80.3% White, and low educational level (5.8 ± 4.3 years of formal schooling). We found 19.6% of the sample presenting AL. The final regression models showed independent and significant association between AL and age (OR = 1.11; 95%IC = 1.03-1.20; p < 0.01), being non-White (OR = 6.47; 95%IC = 1.63-25.58; p < 0.01), and presence of depressive symptoms (OR = 8.38; 95%IC = 2.31-30.47; p < 0.01). However, years of formal schooling, gender, and FI-36 remained statistically non-significant in the model. CONCLUSION: Our data pointed to the presence of depressive symptoms and social variables as significant factors associated with AL. Further studies with more robust samples or longitudinal design will clarify some unanswered questions of our study.

Neuroticismo e satisfação com relacionamentos e com a vida na velhice / Neuroticism and satisfaction with relationships and with life in old age

Resumo Objetivos Investigar a associação entre neuroticismo e satisfação com a vida e apoio social em pessoas idosas casadas; além de verificar se a satisfação com o casamento e com as relações familiares e de amizade são mediadoras dessas associações. Método Trata-se de um estudo transversal realizado com dados do estudo Fragilidade em Idosos Brasileiros (FIBRA). Participaram 94 pessoas idosas recrutadas em domicílios residenciais. Utilizou-se um questionário sociodemográfico; a escala NEO-PI-R-Neuroticismo, integrante do Inventário dos Cinco Grandes Fatores de Personalidade; cinco itens semanticamente adaptados da ISEL (Interpersonal Support Evaluation List), e itens únicos escalares (com cinco pontos cada um) para as variáveis satisfação com as relações conjugais, familiares e de amizade e para satisfação com a vida. Foi realizada análise de equações estruturais via análise de caminhos. Resultados a amostra foi composta em sua maioria por homens (54.6%) que relataram estar muito ou muitíssimo satisfeitos com a vida, o casamento, as amizades e os relacionamentos familiares. Pessoas idosas com menores escores de neuroticismo apresentaram maior satisfação com a vida, o casamento, as amizades e os relacionamentos familiares. Maior satisfação com o casamento e com as amizades relacionaram-se diretamente com mais apoio social. Satisfação com os familiares e com os amigos mediaram a associação entre neuroticismo e satisfação com a vida. Conclusão Indivíduos com níveis mais altos de neuroticismo estão menos satisfeitos com seus relacionamentos e com a vida. Pesquisas longitudinais são necessárias para explicar as relações observadas.

Abstract Objectives To investigate the association between neuroticism and life satisfaction and social support in married older people; in addition to verifying whether satisfaction with marriage and with family and friendship relationships are mediators of these associations. Method A cross-sectional was study carried out with data from the Fragility in Older Adult Brazilians (FIBRA) study. A total of 194 older people recruited from residential households participated in the survey. Instruments used included a sociodemographic questionnaire; the NEO-PI-R-Neuroticism scale from the Big Five Personality Inventory; five items semantically adapted from the ISEL (Interpersonal Support Evaluation List) and single items rated on scales (five points each) for the variables satisfaction with marital, family, and friendship relationships and for satisfaction with life. Structural equation modelling via path analysis was performed. Results The sample comprised individuals who were predominantly men (54.6%), and that reported being satisfied or highly satisfied with life, marriage, friendships, and family relationships. Participants with lower neuroticism scores had higher satisfaction with life, marriage, friendships, and family relationships. Greater satisfaction with marriage and friendships was directly associated with better social support. Satisfaction with family members and friends were variables mediating the association between neuroticism and life satisfaction. Conclusion Individuals with higher levels of neuroticism are less satisfied with their relationships and with life. Longitudinal research is needed to explain the relationships observed.

Digital media use among older adults during the COVID-19 pandemic: a scoping review / O uso das mídias digitais entre idosos durante a pandemia de COVID-19: revisão de escopo

To identify and map the purpose of digital media use among older adults during the coronavirus disease (COVID-19) pandemic. Methods: A scoping review was conducted using the Joanna Briggs Institute methodology involving a search of 7 databases for relevant articles in English, Spanish, and Portuguese published between 2020 and 2021. Most studies were retrieved from the SCOPUS and Web of Science databases. The inclusion criteria for this review were: participants ­ individuals aged ≥ 60 years; concept ­ digital media use during the pandemic; context ­ community-dwelling older adults. Results: The search led to the retrieval of 1992 studies. The titles and abstracts were screened by 2 independent reviewers. Full texts were then extracted according to the inclusion criteria, reaching a total of 12 articles for the review. The results showed that the main purposes of digital media use by older adults were to access and answer surveys sent by e-mail or posted on social media and virtual social networks (eg, Facebook, Instagram, and/or Twitter) and also for telemedicine consultations.

Identificar e mapear a finalidade do uso das mídias digitais entre idosos durante a pandemia. Metodologia: Realizou-se uma scoping review com a utilização da metodologia do Joanna Bringgs Institute, que envolveu uma busca em sete bases de dados de artigos relevantes em inglês, espanhol e português publicados entre 2020 e 2021. A maioria dos artigos recuperados foi: participantes ­ indivíduos com idade ≥ 60 anos; conceito ­ uso de mídia digital durante pandemia; contexto ­ idosos residentes na comunidade.

Associações diretas e indiretas entre autoavaliação de saúde, indicadores objetivos de saúde e neuroticismo em idosos / Direct and indirect associations between self-rated health, objective health indicators and neuroticism in older adults

Resumo Objetivo analisar associações diretas e indiretas entre autoavaliação de saúde, indicadores objetivos de saúde e neuroticismo em idosos Método Os dados foram extraídos dos registros de seguimento (2016-2017) do Estudo da Fragilidade em Idosos Brasileiros (Estudo FIBRA), de base populacional, sobre fragilidade e fatores associados na velhice. Trezentos e noventa e sete indivíduos com idade a partir de 73 anos no seguimento responderam a um item sobre autoavaliação de saúde. Polimedicação, dor crônica e multimorbidade foram autorrelatadas, fadiga foi mensurada pela CES-D, depressão pela EDG e neuroticismo pelo inventário NEO-PI-R. Foi realizada análise de caminhos, para verificar associações diretas e indiretas entre autoavaliação de saúde, indicadores objetivos de saúde e neuroticismo. Resultados Relações mais robustas foram observadas entre sexo e multimorbidade, depressão e neuroticismo, e neuroticismo e autoavaliação de saúde. Destaca-se que neuroticismo mediou a relação entre idade, dor crônica, multimorbidade e depressão com autoavaliação de saúde. Conclusão O neuroticismo é um importante mediador da relação entre autoavaliação de saúde e indicadores objetivos de saúde. Trabalhos longitudinais são necessários para explicar as relações observadas.

Abstract Objective to analyze the direct and indirect associations between self-rated health, objective health indicators and neuroticism in older adults. Method Data were extracted from follow-up records (2016-2017) of the Study of Frailty in Brazilian Elderly (FIBRA Study), a population-based study of frailty and associated variables in old age. Three hundred and ninety-seven individuals aged 73 years and over at follow-up answered an item on self-rated health. Polimedication, chronic pain and multimorbidity were self-reported, fatigue was measured by CES-D, depression by GDS and neuroticism by NEO-PI-R. Path analysis was performed to verify direct and indirect associations between self-rated health, objective health indicators and neuroticism in the follow-up. Results Neuroticism mediated the relationship between sex and age with self-rated health, and between depression and self-rated health. More robust relationships were observed between depression and neuroticism, pain and neuroticism, and sex and neuroticism; the least robust occurred between age and fatigue. Conclusion Neuroticism is an important mediator of the relationship between self-rated health and objective health indicators. Longitudinal work is needed to

Avaliação de seguimento do Estudo Fibra: caracterização sociodemográfica, cognitiva e de fragilidade dos idosos em Campinas e Ermelino Matarazzo, SP / Follow-up evaluation of the Fibra Study: sociodemographic, cognitive, and frailty characterization of older adults in Campinas and Ermelino Matarazzo, SP

Resumo Objetivo Investigar e comparar o perfil sociodemográfico, cognitivo e de fragilidade dos participantes do Estudo Fragilidade em Idosos Brasileiros em medidas de seguimento (SG) e linha de base (LB) realizadas em 2016-2017 e 2008-2009, respectivamente. Métodos Participaram da LB 1.284 idosos residentes em Campinas e Ermelino Matarazzo (SP), Brasil, que compuseram amostra única. No SG foram novamente entrevistados 549 participantes (42,5%); 192 tinham falecido (14,9%) e 543 foram perdidos (42,4%). Em ambos os momentos, foram avaliadas as variáveis sexo, idade, escolaridade, estado conjugal, renda familiar, arranjo de moradia, status cognitivo (Mini-Exame do Estado Mental) e fenótipo de fragilidade (três ou mais de cinco critérios). As diferenças intergrupos e intragrupos foram verificadas pelos testes qui-quadrado de Pearson e de McNemar, respectivamente. O nível de significância foi estabelecido em p<0,05. Resultados Entre os sobreviventes, os participantes eram mais jovens (72,2±5,3 anos) do que entre os falecidos (75,5±6,8 anos) e havia mais idosos casados, com nível educacional mais elevado, sem deficit cognitivo e pré-frágeis. Da LB para o SG, houve aumento estatisticamente significativo do número de idosos que moravam sozinhos (17,1% vs. 22,0%), não tinham companheiro(a) (46,4% vs. 55,4%), tinham renda familiar menor que três salários-mínimos (52,2% vs. 62,2%), apresentavam deficit cognitivo (17,7% vs. 23,5%) e eram frágeis (9,8% vs. 24,5%) Conclusão Da LB para o SG, ocorreu aumento da vulnerabilidade física, cognitiva e social dos idosos. Estes resultados reforçam a importância de políticas públicas que favoreçam a qualidade de vida dos idosos e a redução das iniquidades de saúde ao longo da vida.

Abstract Objective To investigate and compare the sociodemographic, cognitive and frailty profile of participants from the Frailty in Brazilian Older Adults (Fibra) study regarding follow-up (FW) and baseline (BL) measurements carried out in 2016-2017 and 2008-2009, respectively. Methods A total of 1,284 older adults living in Campinas and Ermelino Matarazzo (SP), Brazil, participated in the BL, comprising a pooled sample. At FW, 549 older adults (42.7%) were interviewed again; 192 had died (14.9%) and 543 were lost to follow-up (42.4%). Sex, age, education, marital status, family income, housing arrangement, cognitive status (Mini-Mental State Examination) and frailty phenotype (score ≥3 out of 5) were evaluated at both timepoints. Intergroup and intragroup differences were verified by Pearson's chi-square and McNemar's tests. Statistical significant level was set at p<0.05 Results The survivors were younger (72.2±5.3 years) than the deceased (75.5±6.8 years) and individuals included in the FW were mostly married, higher educated, cognitively unimpaired and pre-frail. Between BL and FW there was an increase in the number of participants who lived alone (17.1% vs. 22.0%), had no partner (46.4% vs. 55.4%), a family income <3 minimum wages (52.2% vs. 62.2%), cognitive impairment (17.7% vs. 23.5%) and frailty (9.8% vs. 24.5%). Conclusion Between BL and FW there was an increase in the physical, cognitive and social vulnerability of the older adults. These results reinforce the importance of public policies that favor the quality of life of older people and a reduction in health inequities throughout life.

Probable sarcopenia is associated with cognitive impairment among community-dwelling older adults: results from the FIBRA study.

BACKGROUND: The link between sarcopenia and cognitive impairment has not yet been thoroughly evaluated, especially among older adults. OBJECTIVE: To evaluate the relationship between probable sarcopenia and cognitive impairment among community-dwelling older adults in two Brazilian cities. METHODS: Probable sarcopenia was assessed using the EWGSOP2 (2018) criteria. Thus, participants were classified as probably having sarcopenia if they had SARC-F (Strength, Assistance in walking, Rise from a chair, Climb stairs and Falls) ≥4 points and low grip strength. Cognitive function was evaluated through the Mini-Mental State Examination (MMSE), verbal fluency (VF) and clock drawing test (CDT). RESULTS: In a sample of 529 older adults (mean age 80.8±4.9 years; mean education 4.2±3.67 years; 70.1% women), 27.3% of the participants had SARC-F≥4, 38.3% had low grip strength and 13.6% were classified as probable sarcopenia cases. After adjusting for possible confounders (age, sex, education, depression, diabetes, hypertension, leisure-time physical activity and obesity), probable sarcopenia was found to be associated with impairment in the MMSE (OR 2.52; 95%CI 1.42‒4.47; p=0.002) and in VF (OR 2.17; 95%CI 1.17‒4.01; p=0.014). Low grip strength was found to be associated with impairment in the MMSE (OR 1.83; 95%CI 1.18‒2.82; p=0.006) and in the CDT (OR 1.79; 95%CI 1.18‒2.73; p=0.006). SARC-F scores were found to be associated with impairment in the MMSE (OR 1.90; 95%CI 1.18‒3.06; p=0.008). CONCLUSION: The results suggested that probable sarcopenia and its components present a significant association with cognitive deficits among community-dwelling older adults.

Factors Associated With Positive Self-Rated Health: Comparing Older Adults in Brazil and in Portugal.

Introduction: Self-rated health is a multidimensional health indicator and a predictor of adverse events in old age. Answers to this assessment are influenced by social, cultural and personality factors. Aim: Exploring common and distinctive characteristics of Brazilian and Portuguese older adults aged 70 and over regarding positive self-rated health according to sociodemographic variables, to functional capacity, to independent performance of basic activities of daily living and to neuroticism, as well as analyzing associations between positive self-rated health and these variables. Methods: The present paper is a comparative and cross-sectional study based on secondary data contained in the databases of the FIBRA (Frailty in Brazilian Older Adults) follow-up study, with 418 Brazilian older adults, and of the DIA (From Disability to Activity: The Challenge of Aging) study, with 380 Portuguese older adults. Both samples had higher percentages of women: 68.4% for Portugal and 69.9% for Brazil. The Brazilian sample had a higher average age (80.31 ± 4.67) than the Portuguese sample (76.80 ± 5.28). Results: The Portuguese older adults had better overall cognition scores, higher handgrip strength and higher neuroticism values than the Brazilian older adults. In the simple and multiple logistic regression analyses, it was found that among Brazilian older adults, subjects with higher scores in the MMSE (OR 1.16; 95% CI 1.08-1.24), regardless of ADL performance (OR 2.13; 95% CI 1.31-3.47) and with scores 24-29 (OR 1.92; 95% CI 1.07-3.43) or 11-23 (OR 2.09; 95% CI 1.15-3.79) in neuroticism were more likely to assess their health as very good/good. On the other hand, the Portuguese older adults with intermediate 24-9 (OR 2.38; 95% CI 1.31-4.33) or low 11-23 (OR 5.31; 95% CI 2.69-10.45) scores in neuroticism were more likely to evaluate their health as very good/good. Conclusion: Based on the findings of the present study and on the existing literature, it may be said that it is possible for people to age while keeping a positive perception of their own health, even in advanced old age; comparisons between the above-mentioned countries, however, point to the need for investments in healthcare systems so that older adults may enjoy greater physical independence and improved mental health.

Reserva cognitiva e os diferentes perfis de ganho cognitivo em idosos: uma scoping review / Cognitive reserve and the different cognitive gain profiles in the aged: a scoping review / Reserva cognitiva y los perfiles diferentes de ganancia cognitiva en los ancianos: una escopulación de revisión

O objetivo desse estudo foi verificar diferentes perfis de ganho cognitivo em idosos para a reserva cognitiva. Trata-se de uma scoping review, utilizando-se PubMed, Medline, Web of Science, Science Direct, Lilacs, SciELO, PsycInfo, PsycNet e AgeLine como base de dados; restringiu-se à busca entre o ano de 2008 e 2018. Identificou-se 2295 estudos e 51 foram elegíveis para a revisão. Dentre os 51 estudos selecionados, encontrou-se nove perfis diferentes para manutenção cognitiva, sendo que cinco estudos não especificaram o perfil. Como conclusão, os perfis encontrados representaram relevância para a teoria de reserva cognitiva e forneceram esclarecimentos de como fatores individuais e de vida diária podem fazer o cérebro mais resiliente no envelhecimento e na velhice; no entanto, esses fatores individuais e o modo como eles contribuem para o desenvolvimento da reserva cognitiva e da manutenção da cognição ainda permanecem obscuros na literatura.

The objective of this study was to verify different profiles of cognitive gain in the elderly for cognitive reserve. This is a scoping review, using PubMed, Medline, Web of Science, Science Direct, Lilacs, SciELO, PsycInfo, PsycNet and AgeLine as a database; the search was restricted between 2008 and 2018. 2295 studies were identified and 51 were eligible for the review. Among 51 studies selected, 9 different profiles were found for cognitive maintenance, and 5 studies did not specify the profile. Conclusion: The profiles found were relevant to cognitive reserve theory and provide insights into how individual factors and daily life can make the brain more resilient in aging and old age. However, those individual factors and how they contribute to development of cognitive reserve and maintenance of cognition still remain obscure in the literature.

α7 nicotinic ACh receptors are necessary for memory recovery and neuroprotection promoted by attention training in amyloid-ß-infused mice.

BACKGROUND AND PURPOSE: Attention training reverses the neurodegeneration and memory loss promoted by infusion of amyloid-ß (Aß) peptide in rats and increases the density of α7 nicotinic ACh receptors (α7nAChRs) in brain areas related to memory. Hence, we aimed to assess the role of α7nAChRs in the memory recovery promoted by attention training. EXPERIMENTAL APPROACH: C57Bl/6 mice were chronically infused with Aß, Aß plus the α7 antagonist methyllycaconitine (MLA), or MLA alone. Control animals were infused with vehicle. Animals were subjected weekly to the active avoidance shuttle box for 4 weeks (attention training). The brain and serum were collected for biochemical and histological analysis. KEY RESULTS: Aß caused cognitive impairment, which was reversed by the weekly training, whereas Aß + MLA also promoted memory loss but with no reversal with weekly training. MLA alone also promoted memory loss but with only partial reversal with the training. Animals infused with Aß alone showed senile plaques in hippocampus, no change in BDNF levels in cortex, hippocampus, and serum, but increased AChE activity in cortex and hippocampus. Co-treatment with MLA increased AChE activity and senile plaque deposition in hippocampus as well as reducing BDNF in hippocampus and serum, suggesting a lack of α7nAChR function leads to a loss of neuroprotection mechanisms. CONCLUSIONS AND IMPLICATIONS: The α7nAChR has a determinant role in memory recovery and brain resilience in the presence of neurodegeneration promoted by Aß peptide. These data support further studies concerning these receptors as pharmacological targets for future therapies.

Enriched Environment Significantly Reduced Senile Plaques in a Transgenic Mice Model of Alzheimer's Disease, Improving Memory.

Alzheimer's disease (AD) is associated with a progressive dementia, and there is good evidence that it is more pronounced in individuals that have fewer stimuli during their lives. Environmental stimulation promotes morphological and functional changes in the brain, leading to amplification of cognitive functions, and has been described in humans and animals. In this study, we evaluated the effects of enriched environment (EE) stimulation on spatial memory and senile plaque formation in transgenic mice PDGFB-APPSwInd (TG) that overexpress the human amyloid precursor protein, normally resulting in an increased density of senile plaques. We compared this group of EE stimulated transgenic mice (TG-EE) with an EE stimulated control group of age-matched C57Bl/6 wild type animals (WT-EE). Both groups were exposed to EE stimulation between the ages of 8 and 12 months. As controls of the experiment, there were a group of TG mice not exposed to EE (TG-Ctrl) and a group of WT mice not exposed to EE (WT-Ctrl). The TG-EE group presented improved spatial memory when compared to the TG-Ctrl animals. In addition, the TG-EE group showed a 69.2% reduction in the total density of senile plaques in the hippocampus when compared to the TG-Ctrl group. In this group, the concentration of senile plaques was greater in the dorsal part of the hippocampus, which is linked to spatial localization, and the reduction of this density after the submission to EE was as high as 85.1%. EE stimulation had no effect on the density of amyloid-ß (Aß) oligomers. However, amyloid scavenger receptor class B member 1 (SR-B1) density was significantly decreased in the TG-Ctrl mice, but not in the TG-EE mice, suggesting that cognitive stimulation had an effect on the formation of a cognitive reserve that could prevent the accumulation of senile plaques. It is suggested that the stimulation of old mice by EE for 4 months led to the formation of brain resilience that protected the brain from the deposition of senile plaques, one of the hallmarks of AD, leading to improvement in spatial memory.
