Frailty and spatialization of older adults in the city of Uberlândia with IVCF-20.

OBJECTIVE: To describe the functional clinical profile of elderly people linked to primary health care, using the Functional Clinical Vulnerability Index (IVCF-20) and to spatialize those with the greatest functional decline by primary health care units in the municipality of Uberlândia, in the state of Minas Gerais (MG), in the year 2022. METHODS: A cross-sectional study with secondary data from the Municipal Health Department of Uberlândia-MG. The variables were compared using Student's t-test, Mann Whitney test, Pearson's chi-square, and multinomial logistic regression to obtain the independent effect of each variable. The significance level adopted was 5% (p < 0.05). The georeferenced database in ArcGIS® was used. RESULTS: 47,182 older adults were evaluated with a mean age of 70.3 years (60 to 113 years), 27,138 of whom were women (57.52%), with a clear predominance of low-risk or robust older adults (69.40%). However, 11.09% are high-risk older adults and 19.52% are at risk of frailty. Older men had independently lower odds of moderate and high risk compared to older women (OR = 0.53; p < 0.001). A high prevalence of polypharmacy was observed, 21.40% of the older adult population, particularly in frail older adults, with a prevalence of 63.08%. There was a greater distribution of frail older adults around the central region of the municipality and in health units with a larger coverage area. The IVCF-20 made it possible to screen frailty in primary health care. CONCLUSION: The instrument is capable of stratifying the risk of older adults in health care networks through primary health care, enabling the application of individualized preventive, promotional, palliative, or rehabilitative interventions, according to the clinical functional stratum of the older adult and the compromised functional domains. Risk stratification and spatial distribution of the frailest older adults can be a good strategy for qualifying health professionals with the aim of maximizing the autonomy and independence of the older adults.

Analysis of the fight against the COVID-19 pandemic in long-term care facilities in the pre-vaccination period.

INTRODUCTION: The COVID-19 pandemic has disproportionately affected individuals residing in Long-Term Care Facilities (LTCFs), necessitating tailored strategies to manage outbreaks. This study examines the outcomes of the ILPI BH project, a collaborative effort between the Municipal Health Department and the Hospital das Clínicas of the Federal University of Minas Gerais, designed to mitigate COVID-19 spread within LTCFs. METHODS: Prospective cohort of secondary data: 1,794 old residents in 99 long-term care facilities of Belo Horizonte, Brazil, were followed from May 2020 to January 2021. The study analyzed the prevention strategies, residents' clinical data, and the characteristics of the long-term care facilities, correlating these variables with the number of infections, hospitalizations, and deaths from COVID-19. It checked absolute numbers and rates of incidence, hospitalization, mortality, and lethality. RESULTS: There have been 58 COVID-19 outbreaks in long-term care facilities. There were 399 cases among residents, 96 hospitalizations for COVID-19 and 48 deaths from COVID-19 (2.7 % of the cohort), with a case fatality rate of 12 %. After multivariate analysis, the intrinsic variables to residents associated with higher mortality risk were higher degree of frailty (OR=1.08; p = 0.004) and the fact of living in a long-term care facility with a considerable proportion of residents' coverage by health plans (OR = 1.01; p = 0.028). Early geriatric follow-up showed an association with a reduction in the number of hospitalizations due to COVID-19. CONCLUSION: The correct classification of the degree of frailty of institutionalized older people seems to have been relevant for predicting mortality from COVID-19. The extensive assistance by private health plans, contrary to what is supposed, did not result in better health protection. Early geriatric follow-up was beneficial and may be an attractive strategy in the face of health emergencies that affect long-term care facilities to reduce hospital admissions.

Frailty in the elderly: screening possibilities in Primary Health Care.

OBJECTIVES: to evaluate two instruments for screening frailty in the elderly in Primary Health Care. METHODS: this is an observational, cross-sectional study, with a quantitative approach, with 396 elderly people. SPSS software helped to perform the statistical analyses. The study used the kappa coefficient and Spearman's correlation. RESULTS: the kappa coefficient between the Clinical-Functional Vulnerability Index 20 and the Edmonton Frailty Scale was 0.496, considered moderate. There was a positive and significant correlation (r = 0.77; p < 0.001) between the frailty conditions and the total score of the two instruments. CONCLUSIONS: when this article assessed fragility through the kappa coefficient, both instruments presented positive correlation and agreement. However, the identification of frailty was higher when it used the Edmonton Frailty Scale.

[Frailty among the elderly assisted by primary health care teams]. / Fragilidade em idosos assistidos por equipes da atenção primária.

The scope of this study was to assess the prevalence and factors associated with frailty among the elderly in Primary Health Care. It is a cross-sectional study carried out with 1750 elderly people in the Southeast of Brazil. The Brazilian Older American Resources and Services Multidimensional Functional Assessment Questionnaire (BOMFAQ) and the Clinical-Functional Vulnerability Index (CFVI) were used for data collection. Descriptive and bivariate analyzes were performed, followed by Poisson regression analysis, with robust variance, to obtain adjusted prevalence ratios (PR). The CFVI identified 357 frail elderly people (20.1%). The variables that remained statistically associated with frailty after multiple analysis were: single/widowed (PR = 1.05; 95%CI = 1.02-1.07); four years of schooling (PR = 1.05; 95%CI = 1.03-1.08); polypathology (PR = 1.05; 95%CI = 1.01-1.09); polypharmacy (PR = 1.21; 95%CI = 1.17-1.26); mental disorder (PR = 1.16; 95%CI = 1.12-1.21); cognitive impairment (PR = 1.71; 95%CI = 1.57-1.86); Daily Living Activity impairment (PR = 1.12; 95%CI = 1.09-1.14); falls (PR = 1.06; 95%CI = 1.03-1.10); hospitalization (PR = 1.39; 95%CI = 1.27-1.52); urinary incontinence and self-perception of health. The conclusion that a significant prevalence of frailty in the study reaffirms the need for a multidimensional approach to the elderly.

Objetivou-se conhecer a prevalência e os fatores associados à fragilidade em idosos na Atenção Primária à Saúde. Trata-se de estudo transversal realizado com1750 idosos no Sudeste do Brasil. Utilizou-se para coleta o Brazilian Older Americans Resources and Services MultiDimensional Function Assessment Questionnaire (BOMFAQ) e o Índice de Vulnerabilidade Clínico-funcional (IVCF-20). Realizaram-se as análises descritivas e bivariadas, seguidas da análise regressão de Poisson, com variância robusta, para obtenção de razões de prevalência ajustadas. O IVCF-20 identificou 357 idosos frágeis (20,1%). As variáveis estatisticamente associadas à fragilidade após análise múltipla foram: estado civil (RP = 1,05; IC95% = 1,02-1,07), escolaridade (RP = 1,05; IC95% = 1,03-1,08), polipatologia (RP = 1,05; IC95% = 1,01-1,09), polifarmácia (RP = 1,21; IC95% = 1,17-1,26), transtorno mental (RP = 1,16; IC95% = 1,12-1,21), comprometimento cognitivo (RP = 1,71; IC95% = 1,57-1,86), comprometimento de atividades de vida diária (RP = 1,12; IC95% = 1,09-1,14), quedas (RP = 1,06; IC95% = 1,03-1,10), internação (RP = 1,39; IC95% = 1,27-1,52) e incontinência urinária, autopercepção da saúde. Concluiu-se que a significante prevalência de fragilidade do estudo reitera a necessidade de abordagem multidimensional do idoso.

Frailty in community-dwelling older people: comparing screening instruments.

OBJECTIVE: To compare the Edmonton Frail Scale (EFS) and Clinical-Functional Vulnerability Index-20 (CFVI-20) instruments regarding degree of agreement and correlation and compare descriptive models with frailty-associated variables in community-dwelling older people in Brazil. METHODS: Cross-sectional study, nested in a population-based and household cohort. Baseline sampling was calculated based on a probabilistic approach by conglomerate in two stages. In the first stage, census tract was used as sampling unit. In the second, the number of households was defined according to the population density of individuals aged ≥ 60 years. The Kappa statistic evaluated the agreement between instruments and Pearson's coefficient their correlation. Factors associated with frailty and high risk of clinical-functional vulnerability were identified by multiple analysis of Poisson regression with robust variance. RESULTS: Kappa statistics was 0.599 and Pearson's correlation coefficient 0.755 (p < 0.001). The EFS found a 28.2% prevalence of frailty, and the CFVI-20 found a 19.5% prevalence of high risk of clinical-functional vulnerability. Age equal to or greater than 80 years, history of stroke, polypharmacy, negative self-perceived health, fall in the past 12 months, and hospitalization in the past 12 months were variables associated with frailty in both instruments after multiple analysis. Less than four years of education, osteoarticular disease, and weight loss were associated with frailty only by EFS, and having a caregiver was associated with a high risk of clinical-functional vulnerability only by CFVI-20. CONCLUSIONS: Although the analyses show moderate agreement and strong positive correlation between the instruments, the indicated prevalence of frailty is discrepant. Our results attest the need to standardize the instrument for assessing frailty in community-dwelling older people.

Robust older adults in primary care: factors associated with successful aging.

OBJECTIVE: To estimate the prevalence of robustness among older adults assisted in primary health care and identify factors in successful aging. METHODS: This is a cross-sectional study conducted with older adults in Northern Minas Gerais, Brazil. Two questionnaires were used for data collection: the Brazilian Older Americans Resources and Services Multidimensional Function Assessment Questionnaire (BOMFAQ) and the Clinical-Functional Vulnerability Index IVCF-20). The adjusted prevalence ratios were obtained by robust Poisson regression. Statistical analysis was performed for older adults in general (60 to 107 years) and stratified by age: from 60 to 79 years and 80 years or more. RESULTS: A total of 1,750 older adults aged 60 to 107 years participated; between them, 48.7% were robust. Older adults aged 60 to 79 years (n = 1,421) and 80 years or more (n = 329) had a prevalence of robustness of 55.4% and 19.3%, respectively. Some factors associated with successful aging were: positive self-perception of health, dancing habits, walking habits, absence of cognitive impairment, absence of depressive symptoms and polypathology, as well as daily life independence. After adjustment by age, the absence of polypathology and independence for activities of daily living stand out for robustness between 60 and 79 years; in those aged 80 years and over, independence for activities of daily living and dance practice presented greater strength of association. CONCLUSION: The prevalence of robust older adults in primary care is considered satisfactory for the older population in general but decreases with age and is associated with the absence of diseases and disabilities. These results denote the need to redesign the health care system, focusing on promoting and preventing clinical-functional vulnerability.

Estimates of the impact of COVID-19 on mortality of institutionalized elderly in Brazil. / Estimativas de impacto da COVID-19 na mortalidade de idosos institucionalizados no Brasil.

The COVID-19 pandemic poses difficulties for long-term care institutions for the elderly, with increased mortality rates for the residents. This study aims to estimate the impact of COVID-19 on mortality of institutionalized elderly in Brazil. Estimates of the percentage of elderly deaths occurring in care homes were calculated for Brazil, States and Regions using estimates for the total number of deaths. The estimation was based upon information available for other countries. The weighted percentage was 44.7% and 107,538 COVID-19 deaths were estimated for the elderly in these institutions in Brazil in 2020. Higher numbers of deaths were expected in the Southeast Region (48,779 deaths), followed by the Northeast Region (28,451 deaths); São Paulo was the most affected State (24,500 deaths). The strong impact of COVID-19 on the elderly population living in long-term care facilities is clear. Estimates for the country exceeded 100,000 elderly people, potentially the most fragile and vulnerable, and are based upon a conservative number of total deaths, in view of other estimates and the alarming situation of death growth in Brazil from COVID-19.

COVID-19 in long-term care facilities for the elderly: laboratory screening and disease dissemination prevention strategies. / COVID-19 nas instituições de longa permanência para idosos: estratégias de rastreamento laboratorial e prevenção da propagação da doença.

An infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the 2019 Novel Coronavirus Disease (COVID-19) pandemic has unveiled a hitherto hidden reality: the vulnerability of the population living in long-term care facilities for the elderly (LTCF). To date, several scientific publications have revealed a concentration of up to 60% of deaths attributed to COVID-19 in such institutions. Most LTFC residents share the primary risk factors currently associated with increased morbimortality due to the COVID-19 infection. It is crucial to define actions to prevent SARS-CoV-2 spread in this environment, besides the usual measures of social distancing and isolation of the carriers of this disease. This paper proposes strategies for the investigation of this infection in LTCF residents and workers using laboratory tests available in Brazil. The early identification of individuals with SARS-CoV-2, who may actively and continuously spread the virus, allows adopting measures aimed at interrupting the local transmission cycle of this infection.

RESUMO OBJETIVO Descrever o perfil clínico funcional dos idosos vinculados à atenção primária à saúde, por meio do Índice de Vulnerabilidade Clínico Funcional (IVCF-20) e realizar a espacialização dos de maior declínio funcional por unidades de atenção primária à saúde no município de Uberlândia-MG, no ano de 2022. MÉTODOS Estudo transversal com dados secundários da Secretaria Municipal de Saúde de Uberlândia-MG. As variáveis foram comparadas através de testes de t de Student, Mann Whitney, qui-quadrado de Pearson e regressão logística multinomial para obter o efeito independente de cada variável. O nível de significância adotado foi de 5% (p < 0,05). Utilizou-se o banco de dados georreferenciado no ArcGIS®. RESULTADOS Foram avaliados 47.182 idosos com idade média de 70,3 anos (60 a 113 anos), sendo 27.138 mulheres (57,52%) e observou-se franco predomínio de idosos de baixo risco ou robustos (69,40%). Todavia, 11,09% são idosos de alto risco e 19,52% estão em risco de fragilização. Idosos do sexo masculino tiveram chance independentemente inferior de risco moderado e alto comparados às mulheres idosas (OR = 0,53; p < 0,001). Foi observado alta prevalência de polifarmácia, 21,40% da população idosa, particularmente nos idosos frágeis, com prevalência de 63,08%. Houve maior distribuição dos idosos frágeis em torno da região central do município e nas unidades de saúde com maior área de abrangência. O IVCF-20 permitiu realizar o rastreio da fragilidade na atenção primária à saúde. CONCLUSÃO O instrumento é capaz de estratificar o risco dos idosos nas redes de atenção à saúde pela atenção primária à saúde, possibilitando a aplicação de intervenções preventivas, promocionais, paliativas ou reabilitadoras individualizadas, conforme o estrato clínico funcional do idoso e os domínios funcionais comprometidos. A estratificação de risco e a distribuição espacial dos idosos mais frágeis pode ser uma boa estratégia de qualificação dos profissionais de saúde com o objetivo de maximizar a autonomia e independência dos idosos.

Preditores clínicos de fragilidade em usuários de serviço de Atenção Secundária em Geriatria e Gerontologia / Clinical predictors of frailty in users of Secondary Care in Geriatrics and Gerontology

Resumo Objetivo Analisar os preditores de saúde associados à fragilidade na população idosa atendida em um serviço de Atenção Secundária em Geriatria e Gerontologia, Belo Horizonte, Minas Gerais, Brasil. Métodos Estudo observacional transversal, envolvendo amostra de 4.323 indivíduos com idade igual ou superior a 60 anos, submetidos a avaliação clínico-funcional. Selecionou-se variáveis sociodemográficas e clínico-funcionais que foram analisadas em comparação à variável dependente do estudo: estrato clínico-funcional por meio da Escala Visual de Fragilidade de forma dicotomizada em frágil e não frágil. Foram realizadas regressões logísticas univariadas. As variáveis com valor p<0,2 foram submetidas à regressão multivariada por meio dos métodos de stepwise e forward de seleção de variáveis na equação. Resultados O valor potencial de explicação do modelo foi de 70,4%. Sete variáveis relacionaram-se à fragilidade: idade (OR 1,016; IC 95%: 1,00-1,028; p<0,001), demência (OR 5,179; IC 95%: 3,839-5,961; p<0,001), sintomatologia depressiva (OR 1,268; IC 95: 1,090-1,475; p=0,002), incontinência urinária (OR 1,330; IC 95%: 1,153-1,535; p<0,001), alterações no padrão de marcha (OR 1,483; IC 95%: 1,287-1,709; p<0,001), circunferência de panturrilha (OR 0,956; IC 95%: 0,932-0,982; p=0,001), IMC (OR 1,026; IC 95%: 1,008-1,044; p=0,005). Conclusão A idade avançada, os quadros demenciais, sintomatologia depressiva, alterações esfincterianas e da marcha associaram-se com fragilidade. Destacam-se a associação entre fragilidade com mensurações reduzidas da circunferência de panturrilha e valores aumentados de IMC e o diagnóstico de demência como a maior força de associação com a síndrome de fragilidade.

Abstract Objective To analyze the health predictors associated with frailty in the older population treated at a Secondary Care Service in Geriatrics and Gerontology, Belo Horizonte, Minas Gerais state, Brazil. Methods A cross-sectional observational study involving a sample of 4,323 individuals aged 60 years or older that underwent a clinical-functional evaluation was conducted. Sociodemographic and clinical-functional variables were analyzed and compared against the dependent variable of the study: clinical-functional stratum, as measured by the Visual Frailty Scale, dichotomized into frail and non-frail. Univariate logistic regressions were performed and the variables with p-value <0.2 were submitted to multivariate regression by stepwise and forward methods of selecting variables in the equation. Results The potential explanatory value of the model was 70.4%. Seven variables were associated with frailty: age (OR 1.016; 95%CI: 1.001-1.028; p<0.001), dementia (OR 5.179; 95%CI: 3.839-5.961; p<0.001), depressive symptoms (OR 1.268; 95%CI: 1.090-1.475; p=0.002), urinary incontinence (OR 1.330; 95%CI: 1.153-1.535; p<0.001), changes in gait speed (OR 1.483; 95%CI: 1.287-1.709; p<0.001), calf circumference (OR 0.956; 95%CI: 0.932-0.982; p=0.001), and BMI (OR 1.026; 95%CI: 1.008-1.044; p=0.005). Conclusion Advanced age, dementia, depressive symptoms, and continence and gait changes were associated with frailty. The study results reveal an association of reduced calf circumference and increased BMI values with frailty in older adults and that dementia diagnosis had the strongest association with the frailty syndrome.

Clinical-Functional Vulnerability Index-20 (IVCF-20): rapid recognition of frail older adults.

OBJECTIVE: To evaluate the adequacy of the Clinical-Functional Vulnerability Index-20, a rapid triage instrument to test vulnerability in Brazilian older adults, for the use in primary health care. METHODS: The study included convenience sample of 397 patients aged older than or equal to 60 years attended at Centro de Referência para o Idoso (Reference Center for Older Adults) and of 52 older adults the same age attended at the community. The results of the questionnaire, consisting of 20 questions, were compared with those of the Comprehensive Geriatric Assessment, considered a reference for identifying frail older adults. Spearman's correlation was evaluated in the Clinical-Functional Vulnerability Index-20 with the Comprehensive Geriatric Assessment; the validity was verified by the area under the ROC curve; reliability was estimated by the percentage of agreement among evaluators and by the kappa coefficient, both with quadratic weighted. The cut-off point was obtained based on the higher accuracy criterion. Cronbach's alpha, a measure of internal consistency, was estimated. RESULTS: The Spearman's correlation coefficient was high and positive for both groups (0.792 for older adults attended at the Reference Center and 0.305 for older adults from the community [p < 0.001]). The area under the ROC curve for older adults attended at the Reference Center was substantial (0.903). The cut-off point obtained was six, and older adults with scores in Clinical-Functional Vulnerability Index-20 above that value had strong possibility of being frail. For older adults from the community, the quadratic weighted agreement among evaluators was 99.5%, and the global quadratic weighted kappa coefficient was 0.94. Cronbach's alpha was high for older adults attended at the Reference Center (0.861) and those attended at the community (0.740). CONCLUSIONS: The Clinical-Functional Vulnerability Index-20 questionnaire, in the sample examined, turned out to be positively correlated with the Comprehensive Geriatric Assessment, in addition to the results indicating a high degree of validity and reliability. Thus, the Clinical-Functional Vulnerability Index-20 proves to be viable as a triage instrument in the primary health care that identifies frail older adults (older adults at risk of weakening and frail older adults). OBJETIVO: Avaliar a adequação do Índice de Vulnerabilidade Clínico-Funcional-20 , instrumento de triagem rápida de vulnerabilidade em idosos brasileiros, para utilização pela atenção básica. O estudo incluiu amostra de conveniência de 397 pacientes com idade maior ou igual a 60 anos atendidos em um Centro de Referência para o Idoso e de 52 idosos da mesma idade atendidos na comunidade. Os resultados do questionário, constituído por 20 perguntas, foram comparados com aqueles da Avaliação Geriátrica Ampla, considerada referência para identificação do idoso frágil. Foi avaliada a correlação de Spearman do Índice de Vulnerabilidade Clínico-Funcional-20 com a Avaliação Geriátrica Ampla; a validade foi verificada pela área sob a curva ROC; a confiabilidade foi estimada pelo percentual de concordância entre avaliadores e coeficiente kappa, ambos com ponderação quadrática. Obteve-se ponto de corte com base no critério de maior acurácia. O alfa de Cronbach, medida de consistência interna, foi calculado. O coeficiente de correlação de Spearman foi elevado e positivo em ambos os grupos (0,792 para idosos atendidos no Centro de Referência para o Idoso e 0,305 para idosos da comunidade [p < 0,001]). A área sob a curva ROC para idosos atendidos no Centro de Referência para o Idoso foi substancial (0,903). O ponto de corte obtido foi seis e idosos com pontuação no Índice de Vulnerabilidade Clínico-Funcional-20 acima desse valor tinham forte possibilidade de serem frágeis. Para idosos da comunidade, a concordância ponderada quadrática entre avaliadores foi 99,5% e o coeficiente kappa ponderado quadrático global, 0,94. O alfa de Cronbach foi elevado para idosos atendidos no Centro de Referência para o Idoso (0,861) e da comunidade (0,740). CONCLUSÕES: O questionário do Índice de Vulnerabilidade Clínico-Funcional-20, na amostra analisada, mostrou ser positivamente correlacionado com a Avaliação Geriátrica Ampla, além de os resultados indicarem alto grau de validade e confiabilidade. Assim, o Índice de Vulnerabilidade Clínico-Funcional-20 se mostra viável como instrumento de rastreio na atenção básica que identifica o idoso com fragilidade (idoso em risco de fragilização e idoso frágil).

Clinical Frailty Scale em idosos atendidos no Serviço Hospitalar de Emergência: a fragilidade basal é um bom preditor de mortalidade em 90 dias? / Clinical Frailty Scale in older adults admitted at Emergency Department: is baseline frailty a good predictor of Ninety-Day Mortality?

Resumo Objetivo Avaliar a capacidade da Clinical Frailty Scale (CFS) em predizer a mortalidade em até 90 dias e outros desfechos desfavoráveis em idosos admitidos em um Serviço Hospitalar de Emergência (SHE). Método Estudo de coorte prospectivo que incluiu idosos admitidos e que permaneceram por pelo menos uma noite no SHE de um hospital público terciário. O grau de fragilidade basal foi avaliado através da CFS e sua pontuação, o preditor estudado, por meio da curva Receiver Operator Characteristics (ROC). Analisou-se como desfecho primário a mortalidade em 90 dias. Considerou-se como desfechos secundários: mortalidade em 180 dias, declínio funcional, readmissão no SHE, reinternação e necessidade de atenção domiciliar. Resultados 206 participantes foram incluídos. Dos 127 idosos frágeis, 40 (31,5%) faleceram até o 90º dia comparado a 5 (6,3%) do grupo não frágil (p<0,001). Após ajuste para variáveis demográficas e clínicas, a fragilidade manteve-se no modelo como um preditor independente de mortalidade em 90 dias da admissão. A acurácia obtida pela curva ROC (AUROC) para predição de mortalidade em 90 dias foi de 0,81. Para mortalidade em 180 dias foi 0,80; para necessidade de atenção domiciliar, 0,77; e para reinternação, 0,65. Para os demais desfechos estudados, a acurácia não foi significativa. Conclusão A fragilidade basal medida pela CFS é um bom preditor de mortalidade em 90 e 180 dias e de necessidade de atenção domiciliar em idosos admitidos no SHE. Sua aplicação nesse cenário pode auxiliar na tomada de decisões clínicas.

Abstract Objective To evaluate the ability of the Clinical Frailty Scale (CFS) to predict 90-day mortality and other poor outcomes in older adults admitted at a Hospital Emergency Department (ED). Method This is a prospective cohort study including older adults admitted at ED of a Public Hospital who spent at least one night in it. The degree of baseline frailty was assessed through the CFS, and its score was the predictor studied, through the Receiver Operator Characteristics (ROC) curve analysis. We analyzed 90-day mortality as a primary outcome. The following outcomes were considered as secondary ones: mortality, functional decline, readmittance to ED, readmission and need for home care. Results 206 participants were included. Of the 127 frail older adults, 40 (31.5%) died before the 90th day compared to 5 (6.3%) in the non-frail group (p<0.001). After adjustment for demographic and clinical variables, frailty remained in the model as an independent predictor of 90-day mortality. The accuracy obtained by the ROC curve (AUROC) for predicting 90-day mortality was 0.81. For 180-day mortality, 0.80, for the need for home care, 0.77 for readmission, 0.65. For the other outcomes studied, the accuracy was not significant. Conclusion Baseline frailty measured by the CFS is a good predictor of 90 and 180-day mortality and needing for home care in older adults admitted to ED. Its application in this setting might help clinical decision-making.

[Access to medicines for Alzheimer's disease provided by the Brazilian Unified National Health System in Minas Gerais State, Brazil]. / Acesso aos medicamentos para tratamento da doença de Alzheimer fornecidos pelo Sistema Único de Saúde em Minas Gerais, Brasil.

This study evaluated barriers to access to treatment for Alzheimer's disease based on administrative cases involving cholinesterase inhibitors (ChEIs) and submitted to the Minas Gerais State Health Secretariat in Brazil in 2012 and 2013. Drawing on data from 165 randomly selected cases, the study addressed the following dimensions of access: geographic accessibility, accommodation, acceptability, availability, and affordability. The administrative processing to supply ChEIs took an average of 39 days and was influenced by characteristics of the path taken by the user. The majority of the prescribers met less than 80% of the required criteria in the Clinical Protocol and Therapeutic Guidelines (CPTG) for Alzheimer's disease. As a result, 38% of requests for medication were denied. Private treatment with ChEIs cost the equivalent of 21 days of the monthly minimum wage. In conclusion, bureaucratic administrative procedures and prescribers' difficulty in following the CPTG hindered access to treatment of Alzheimer's disease and imposed a heavy burden on patients' pockets.

Lack of Association between Genetic Polymorphism of Circadian Genes (PER2, PER3, CLOCK and OX2R) with Late Onset Depression and Alzheimer's Disease in a Sample of a Brazilian Population (Circadian Genes, Late-Onset Depression and Alzheimer's Disease).

OBJECTIVES: This study aims to evaluate the association between polymorphisms in circadian genes and Alzheimer's disease (AD) and/or late-onset depression (LOD). AD pathology leads to circadian disturbances, with clear negative influence on quality of life. In addition, there is an increasing evidence that regulators of circadian system have effects on AD and LOD pathology. DESIGN AND SUBJECTS: An exploratory case-control study designed to evaluate SNPs in the PER2, PER3, CLOCK and OX2R genes in a sample composed by 249 AD, 222 LOD and 112 healthy individuals. MEASURES: The participants were evaluated using DSM-IV criteria for LOD and NINCDS-ADRDA for AD. RESULTS: In allelic analysis, the OX2R SNP, rs2134294, showed an association of allele C with LOD (p =0.02, OR= 1.6) and AD (p=0.04, OR =1.5). The rs2134294 also showed a genotypic association C/C (p =0.01) for higher risk to develop LOD compared to the control group, with an odd's ratio of 2.7. The rs9370399 (OX2R) has also shown an association between A allele (p=0.03, OR= 1.4) and AD. These results do not persist after a 1,000 permutations test. For other markers of the OX2R gene and for all other markers of this study no association was found. CONCLUSION: In conclusion, the present study found that the investigated Circadian Genes (PER2, PER3, CLOCK and OX2R) polymorphisms were not associated with LOD or AD.

COVID-19 nas instituições de longa permanência para idosos: estratégias de rastreamento laboratorial e prevenção da propagação da doença / COVID-19 in long-term care facilities for the elderly: laboratory screening and disease dissemination prevention strategies

Resumo A pandemia da "novel coronavirus disease" 2019 (COVID-19), infecção causada pelo coronavírus 2 da síndrome respiratória aguda grave (SARS-CoV-2), tem descortinado uma realidade até então oculta: a vulnerabilidade da população residente em instituições de longa permanência para idosos (ILPI). Diversas publicações científicas têm revelado a concentração de até 60% dos óbitos atribuídos à COVID-19 em tais instituições. A maioria dos residentes em ILPI reúnem os principais fatores de risco para morbimortalidade pela COVID-19, o que torna imprescindível a definição de ações voltadas à prevenção da transmissibilidade do SARS-CoV-2 neste ambiente, além das medidas usuais de distanciamento social e isolamento dos portadores da doença. Propõem-se, no presente artigo, estratégias de rastreamento da infecção em residentes e trabalhadores de ILPI por meio de testes laboratoriais disponíveis no Brasil. A identificação precoce de indivíduos portadores do SARS-CoV-2 com possibilidades de transmissão ativa e continuada do vírus permite a adoção de medidas que interrompam o ciclo de transmissão local da infecção.

Abstract An infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the 2019 Novel Coronavirus Disease (COVID-19) pandemic has unveiled a hitherto hidden reality: the vulnerability of the population living in long-term care facilities for the elderly (LTCF). To date, several scientific publications have revealed a concentration of up to 60% of deaths attributed to COVID-19 in such institutions. Most LTFC residents share the primary risk factors currently associated with increased morbimortality due to the COVID-19 infection. It is crucial to define actions to prevent SARS-CoV-2 spread in this environment, besides the usual measures of social distancing and isolation of the carriers of this disease. This paper proposes strategies for the investigation of this infection in LTCF residents and workers using laboratory tests available in Brazil. The early identification of individuals with SARS-CoV-2, who may actively and continuously spread the virus, allows adopting measures aimed at interrupting the local transmission cycle of this infection.

Robust older adults in primary care: factors associated with successful aging / Idosos robustos na atenção primária: fatores associados ao envelhecimento bem-sucedido

ABSTRACT OBJECTIVE To estimate the prevalence of robustness among older adults assisted in primary health care and identify factors in successful aging. METHODS This is a cross-sectional study conducted with older adults in Northern Minas Gerais, Brazil. Two questionnaires were used for data collection: the Brazilian Older Americans Resources and Services Multidimensional Function Assessment Questionnaire (BOMFAQ) and the Clinical-Functional Vulnerability Index IVCF-20). The adjusted prevalence ratios were obtained by robust Poisson regression. Statistical analysis was performed for older adults in general (60 to 107 years) and stratified by age: from 60 to 79 years and 80 years or more. RESULTS A total of 1,750 older adults aged 60 to 107 years participated; between them, 48.7% were robust. Older adults aged 60 to 79 years (n = 1,421) and 80 years or more (n = 329) had a prevalence of robustness of 55.4% and 19.3%, respectively. Some factors associated with successful aging were: positive self-perception of health, dancing habits, walking habits, absence of cognitive impairment, absence of depressive symptoms and polypathology, as well as daily life independence. After adjustment by age, the absence of polypathology and independence for activities of daily living stand out for robustness between 60 and 79 years; in those aged 80 years and over, independence for activities of daily living and dance practice presented greater strength of association. CONCLUSION The prevalence of robust older adults in primary care is considered satisfactory for the older population in general but decreases with age and is associated with the absence of diseases and disabilities. These results denote the need to redesign the health care system, focusing on promoting and preventing clinical-functional vulnerability.

RESUMO OBJETIVO Estimar a prevalência de robustez entre idosos assistidos na atenção primária à saúde e identificar fatores de envelhecimento bem-sucedido. MÉTODOS Trata-se de pesquisa transversal, realizada com idosos no norte de Minas Gerais, Brasil. Foram utilizados dois questionários para coleta de dados: Brazilian Older Americans Resources and Services Multidimensional Function Assessment Questionnaire (BOMFAQ) e Índice de Vulnerabilidade Clínico-Funcional (IVCF-20). As razões de prevalências ajustadas foram obtidas por análise de regressão de Poisson múltipla com variância robusta. A análise estatística foi realizada para os idosos em geral (60 a 107 anos) e estratificada por idade: de 60 a 79 anos e 80 anos ou mais. RESULTADOS Participaram 1.750 idosos, com idade de 60 a 107 anos, sendo 48,7% robustos. Idosos de 60 a 79 anos (n = 1.421) e 80 anos ou mais (n = 329) apresentaram prevalência de robustez de 55,4% e 19,3%, respectivamente. Associaram-se ao envelhecimento bem-sucedido: autopercepção positiva da saúde, dançar, fazer caminhada, não ter comprometimento cognitivo, ausência de sintomas depressivos e de polipatologia, além de independência para atividades de vida diária. Após ajuste por idade, destacam-se para robustez entre 60 a 79 anos a ausência de polipatologia e a independência para atividades de vida diária; naqueles com 80 anos e mais, a independência para atividades de vida diária e a prática de dança apresentaram maior força de associação. CONCLUSÃO A prevalência de idosos robustos na atenção primária pode ser considerada satisfatória para os idosos em geral, mas reduz com a idade e se associa com a ausência de doenças e incapacidades. Esses resultados denotam a necessidade de redesenhar o sistema de atenção à saúde, com foco na promoção e prevenção da vulnerabilidade clínico-funcional.

Padrão alimentar de idosos longevos não frágeis e sua relação com baixo peso, massa, força muscular e teste de velocidade de marcha / Dietary pattern of non-frail very old people and relationship with underweight, muscle mass and strength and gait speed test

Resumo Objetivos Identificar o padrão alimentar de idosos longevos não frágeis e avaliar a associação desse padrão a composição corporal, força muscular e teste de velocidade de marcha. Métodos Estudo transversal com uma amostra de 96 idosos com idade ≥80 anos, não frágeis. O consumo alimentar foi analisado por meio de três registros alimentares não consecutivos e a massa muscular por meio da área muscular do braço. A força muscular foi medida por dinamometria. A análise de Cluster foi utilizada para distinguir os padrões alimentares. Realizou-se a análise bivariada e a Regressão de Poisson multivariado, explorando a relação dos padrões alimentares com as variáveis independentes específicas. Resultados Foram identificados dois padrões alimentares, rotulados de padrão saudável e padrão tradicional. A prevalência de baixo peso nos idosos do padrão tradicional foi 10% (IC95% 1,01-1,20) maior do que nos idosos do padrão saudável e está prevalência praticamente manteve-se (RP 1,09; IC 1,00-1,18) no modelo ajustado por funcionalidade. Quanto a classificação da área muscular do braço os idosos do padrão tradicional apresentaram 15% (IC95% 1,00-1,32) maior prevalência de baixa massa muscular, quando comparada com os idosos do padrão saudável. Essa prevalência no modelo ajustado por funcionalidade, deixou de ser estatisticamente significativa. Não foi encontrada associação do padrão alimentar com força muscular e teste de velocidade de marcha. Conclusões Os achados demonstraram que os idosos adeptos ao padrão alimentar saudável tem menor risco de baixo peso e que a baixa massa muscular está provavelmente mais associada a funcionalidade do que ao padrão alimentar.

Abstract Objectives To identify the dietary pattern of non-frail very old people and to evaluate the association of this pattern with body composition, strength, and gait speed. Methods Cross-sectional study with a sample of 96 old people aged 80 or over, non-frail. Food consumption was analyzed using three non-consecutive food records. Muscle mass was assessed using arm muscular area. Muscle strength was measured by grip strength. Cluster analysis was used to distinguish dietary patterns. Bivariate analysis and multivariate Poisson Regression were performed, exploring the relationship between dietary patterns and specific independent variables. Results Two dietary patterns were identified, labeled healthy and traditional. The prevalence of underweight among the old people of the traditional pattern was 10% (95%CI 1.01-1.20) higher than among the old people of the healthy pattern and this prevalence was practically maintained (PR 1.09; 95%CI 1.00-1.18) in the model adjusted by functionality. Regarding the classification of the arm muscular area, the old people of the traditional pattern presented 15% (95%CI 1.00-1.32) more prevalence of low muscle mass, when compared with the old people of the healthy pattern. This prevalence in the functionality-adjusted model was no longer statistically significant. No association was found between dietary pattern and strength and gait speed. Conclusions The findings showed that old people who adhere to healthy dietary patterns have a lower risk of underweight and that low muscle mass is probably more associated with functionality than with dietary patterns.
