Asociación de la fragilidad con el uso de servicios de salud en adultos mayores. Un análisis secundario del Estudio Nacional sobre Salud y Envejecimiento en México / Association of frailty with the use of health services in older adults. A secondary analysis of the Mexican Health and Aging Study

Resumen Antecedentes: La fragilidad se ha relacionado con desenlaces adversos, pero aún es escasa la evidencia sobre su asociación con el uso de servicios de salud. Objetivo: Evidenciar la asociación de la fragilidad con el uso de servicios de salud en adultos mexicanos mayores de 60 años. Material y métodos: Análisis del Estudio Nacional sobre Salud y Envejecimiento en México para 2015 (basal) y 2018 (seguimiento). La fragilidad se definió con el índice de fragilidad. Fueron incluidos los siguientes desenlaces: hospitalización, visitas médicas, cirugía mayor, procedimientos quirúrgicos menores y visitas al dentista. Se utilizaron modelos de riesgos competitivos y de número de eventos (regresión negativa binomial). Resultados: Se incluyeron 8526 individuos, cuya edad promedio fue de 70.8 %; 55.8 % correspondió al sexo femenino. De acuerdo con los resultados, los días de hospitalización y el número de procedimientos menores se asociaron a fragilidad. Conclusiones: La fragilidad podría ser un parámetro útil en la planeación de los servicios de salud para los adultos mayores. Por otro lado, su evaluación permitiría priorizar la atención a quienes presenten mayor riesgo de desenlaces adversos.

Abstract Background: Frailty has been related to adverse outcomes, but evidence on its association with the use of health services is still scarce. Objective: The purpose of this work was to determine the association of frailty with the use of health services in Mexican adults older than 60 years. Material and methods: Analysis of the Mexican Health and Aging Study for the years 2015 (baseline) and 2018 (follow-up). Frailty was defined with the frailty index. The following outcomes were included: hospitalization, medical visits, major surgery, minor surgical procedures, and dental visits. Competing risk and count analyses (negative binomial regression) were performed. Results: A total of 8,526 individuals were included, whose average age was 70.8%; 55.8% corresponded to the female gender. According to the results, hospitalization days and the number of minor procedures were associated with frailty. Conclusions: Frailty could be useful in the planning of health services for older adults. On the other hand, its evaluation would allow prioritizing care for those who are at higher risk of adverse outcomes.

Depressive symptoms and self-rated health among Brazilian older adults: baseline data from the ELSI-Brazil study

Objective: To investigate whether having a higher number of depressive symptoms is associated with negative self-rated health (SRH) even in the absence of illness. Methods: This is a secondary analysis of baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil), conducted in 2015-2016, using a national sample of 9,412 people aged 50 or over. SRH was dichotomized into poor or very poor and very good or excellent, good, or average. Depressive symptoms were assessed through the eight-item Center for Epidemiologic Studies Depression Scale (CES-D8). Sociodemographic variables, information about unhealthy behaviors, and the number of chronic conditions were also analyzed. Results: Having depressive symptoms was strongly associated with poor or very poor SRH both in the unadjusted and adjusted analyses. The magnitude of the association was reduced when the number of chronic illnesses was included in the multivariate analysis, along with the other sociodemographic variables and unhealthy behaviors (OR 1.35, 95%CI 1.31-1.39). Conclusion: Having depressive symptoms may contribute towards having a poorer perception of health, even in the absence of health conditions. SRH is a multidimensional construct that can accurately reflect a person's state of general mental health.

Prevalência e fatores associados à fragilidade em pessoas idosas hipertensas por meio da Escala de Fragilidade de Edmonton e Índice de Vulnerabilidade Clínico Funcional-20 / Prevalence and factors associated with frailty in older adults with hypertension using the Edmonton Frail Scale and the Clinical Functional Vulnerability Index-20

Resumo Objetivo Avaliar a prevalência de fragilidade e comparar as variáveis associadas a essa fragilidade em pessoas idosas hipertensas comunitárias brasileiras por meio da Escala de Fragilidade de Edmonton (EFE) e o Índice de Vulnerabilidade Clínico-Funcional-20 (IVCF-20). Métodos Trata-se de um estudo transversal e analítico, conduzido com pessoas idosas hipertensas comunitárias com idade ≥60 anos, residentes na cidade de Montes Claros, Minas Gerais, Brasil. A seleção da amostra seguiu o modelo probabilístico por conglomerado. Os dados foram coletados entre novembro de 2016 e fevereiro de 2017 por meio de aplicação de questionário em domicílio. Foram analisadas variáveis demográficas, socioeconômicas e clínico-assistenciais. Utilizou-se a regressão de Poisson com variância robusta para obter as razões de prevalência brutas e ajustadas. Resultados Participaram 281 pessoas idosas hipertensas. A prevalência geral de fragilidade pela EFE foi de 31,3% e pelo IVCF-20 foi de 22,1%. As variáveis, que após a análise múltipla, foram estatisticamente associadas à fragilidade em idosos hipertensos, pela EFE e IVCF-20 simultaneamente, foram: idade avançada (80 anos ou mais), apresentar como comorbidade artrite reumatoide/artrose, acidente vascular encefálico, autopercepção de saúde negativa, quedas e internações nos últimos 12 meses. Apenas pela EFE, menos de 4 anos de estudo, não ter prática religiosa e não possuir renda própria foram as variáveis associadas. Enquanto pelo IVCF-20, somente a renda familiar mensal associou-se à fragilidade. Conclusão Verificou-se que a fragilidade avaliada pela EFE e pelo IVCF-20 possui similaridade, no entanto, a EFE é mais sensível. Esses resultados demonstram a necessidade dos profissionais da saúde identifiquem precocemente a fragilidade.

Abstract Objective To assess the prevalence of frailty and compare the variables associated with frailty in Brazilian community-dwelling older adults with hypertension using the Edmonton Frail Scale (EFS) and the Clinical Functional Vulnerability Index-20 (IVCF-20). Methods This is a cross-sectional analytical study conducted with community-dwelling older adults with hypertension aged ≥60 years residing in the city of Montes Claros, Minas Gerais, Brazil. Sample selection followed a probabilistic cluster sampling model. Data were collected between November 2016 and February 2017 through in-home questionnaire administration. Demographic, socioeconomic, and clinical-care variables were analyzed. Poisson regression with robust variance was used to obtain crude and adjusted prevalence ratios. Results A total of 281 older adults with hypertension participated in the study. The overall prevalence of frailty as assessed by the EFS was 31.3%, and by the IVCF-20 was 22.1%. Variables that were statistically associated with frailty in older adults with hypertension, as determined by both the EFS and IVCF-20 simultaneously, were: advanced age (80 years or older), comorbidities such as rheumatoid arthritis/osteoarthritis, stroke, negative self-perception of health, falls, and hospitalizations in the last 12 months. Only by the EFS, variables associated with frailty included less than 4 years of education, absence of religious practice, and lack of personal income. Meanwhile, according to the IVCF-20, only monthly family income was associated with frailty. Conclusion It was found that frailty assessed by EFS and IVCF-20 exhibits similarity; however, EFS is more sensitive. These findings underscore the imperative for healthcare professionals to early identify frailty.

Subpoblaciones de linfocitos T en adultos mayores cubanos con leucemia linfoide crónica / Subpopulations of T lymphocytes in Cuban older adults with chronic lymphoid leukemia

Introducción: la inmunosenescencia está asociada con un mayor riesgo de desarrollo de cáncer. Dentro de las hemopatías malignas que afectan a este grupo de edad, está la leucemia linfoide crónica (LLC), caracterizada por trastornos en la inmunidad adaptativa que incluye las subpoblaciones de linfocitos T. Objetivo: Determinar la frecuencia de las subpoblaciones de linfocitos T en los pacientes adultos mayores con leucemia linfoide crónica evaluados en el Instituto de Hematología e Inmunología de Cuba. Métodos: Se realizó un estudio transversal en 30 adultos mayores con leucemia linfoide crónica. Se cuantificaron los linfocitos TCD3+CD4+ y TCD3+CD8+ en sangre periférica por citometría de flujo. Para la lectura y el análisis de los datos se empleó un citómetro de flujo Beckman Coulter Gallios. Se utilizaron los valores porcentuales, la media y la desviación estándar. Se consideró estadísticamente significativo si p≤0.05. Resultados: Hubo un predominio de hombres que representaron el 56,7 por ciento y del grupo de 70-79 años de edad. No se reportó ningún adulto mayor con LLC con valores altos ni normales de linfocitos TCD3+CD4+. Predominaron los hombres con valores bajos porcentuales de linfocitos TCD3+CD4+, TCD3+CD8+ e inversión del índice CD4/CD8 en relación con las mujeres. Conclusiones: Los adultos mayores con LLC presentan alteraciones en el número de las subpoblaciones de linfocitos T. La acción de estas células en relación al crecimiento de células B malignas aún es desconocido y resulta importante determinar si esto puede reflejar un intento de evasión de las células tumorales al control inmunológico(AU)

Introduction: Immunosenescence is associated with an increased risk of cancer development. Among the malignant hemopathies that affect this age group, it is chronic lymphoid leukemia (CLL), characterized by disorders in adaptive immunity, which include subpopulations of T lymphocytes. Objective: To determine frequency of T lymphocyte subpopulations in older adult patients with chronic lymphoid leukemia evaluated at the Institute of Hematology and Immunology of Cuba. Methods: A cross-sectional study was conducted in 30 older adults with chronic lymphoid leukemia. TCD3+CD4+ and TCD3+CD8+ lymphocytes were quantified in peripheral blood by flow cytometry. A Beckman Coulter Gallios flow cytometer was used to read and analyze the data. The percentage values, the mean and the standard deviation were used. It was considered statistically significant if p≤0.05. Results: There was a predominance of men who represented 56.7 percent and the age group of 70-79 years. No older adults with CLL with high or normal values of TCD3+CD4+ lymphocytes were reported. Men predominated with low percentage values of TCD3+CD4+, TCD3+CD8+ lymphocytes and inversion of the CD4/CD8 ratio in relation to women. Conclusions: Older adult with CLL present alterations in the number of T lymphocyte subpopulations. The role of these cells in relation to the growth of malignant B cells it is unknown and it turns out important to determine if this may reflect an attempt to evade tumor cells from immune control(AU)

Voice and Temporal Auditory Processing in Elderly People: A Correlation Study

Abstract Introduction The voice and hearing can be affected to different degrees by aging, which can cause communication difficulties for elderly people. Vocal production requires effective temporal auditory processing at central levels within the nervous system, which can be compromised by the aging process. Objective To analyze the correlation between voice and temporal auditory processing in older adults. Materials and Methods A total of 40 elderly people aged 60 years or older were subdivided into 2 groups according to the presence or absence of vocal symptoms measured by the Voice Symptom Scale. All of the participants were submitted to auditory temporal tests, vocal self-assessment, and acoustic and perceptual auditory analyses of voice. Results Most of the subjects assessed had decreased voice intensity and normal variability in terms of vocal quality. The performance was normal in the Pitch Pattern Sequence test and altered in the Random Gap Detection test. In the Masking Period Pattern test, the detection thresholds for the target signal were increased in the presence of masking in different temporal target signal positions. Only pitch differed between the two groups. There were differences between the genders regarding frequency, shimmer, the overall severity of the alteration, and roughness. There was a correlation regarding temporal resolution ability and the overall severity of the alteration and roughness of the voice. Conclusion There is a central auditory impairment in temporal resolution which is correlated with vocal alterations in the elderly.

Para as buscas foram acessadas as bases MEDLINE, Web of Science, Scopus, SciELO e a literatura cinzenta, por meio do Google Scholar. Resultados Dos 1.194 estudos encontrados, selecionaram-se 189 artigos submetidos aos critérios de elegibilidade. Os países precursores nas publicações foram Austrália e Estados Unidos, e o ápice das pesquisas ocorreu entre 2013 e 2014. Os participantes dos estudos eram pessoas idosas saudáveis, 63,49% (120); seguidos de 17,46% (33) com doença de Alzheimer; 11,11% (21) com Transtorno Neurocognitivo Leve; 6,88% (13) com doença de Parkinson; e 19,58% (37) com outras comorbidades. Diferentes tipos de intervenções foram identificadas nos estudos, destas, 94,02% (178) avaliaram a eficácia de instrumentos que mensuram a aptidão do motorista idoso. Conclusão Houve predominância de estudos na busca de instrumentos de avaliação que mensurassem a funcionalidade do condutor idoso. Esse fato ratifica a importância de avaliação padronizada, validada e economicamente viável que colabore na identificação do motorista em risco. Evidenciou-se a necessidade de intervenções para a prática da geriatria e gerontologia, por meio de ações para formação de equipe multidisciplinar especializada em condução veicular, de modo a adequar as diretrizes de licenciamento a fim de atender às especificidades dos condutores idosos, considerando os aspectos sociais, econômicos, políticos e educacionais, especialmente nos departamentos de trânsito brasileiro.

Abstract Objective To map national and international scientific evidence regarding driving by older adults. Method Scope review based on the manual proposed by the Joanna Briggs Institute. Searches were conducted in the MEDLINE, Web of Science, Scopus, SciELO databases, and grey literature through Google Scholar. Results Out of 1,194 studies identified, 189 papers meeting eligibility criteria were selected. Pioneering countries in publications were Australia and the United States, with the peak of research occurring between 2013 and 2014. Study participants included healthy older adults (63.49%, 120), followed by those with Alzheimer's disease (17.46%, 33), Mild Neurocognitive Disorder (11.11%, 21), Parkinson's disease (6.88%, 13), and other comorbidities (19.58%, 37). Various interventions were identified, with 94.02% (178) assessing the effectiveness of instruments measuring the fitness of older drivers. Conclusion There was a prevalence of studies aimed at identifying assessment tools to measure the functionality of older drivers. This underscores the importance of standardized, validated, and economically viable assessments that contribute to identifying at-risk drivers. The need for interventions in geriatrics and gerontology was evident, emphasizing the necessity for actions to establish a specialized multidisciplinary team in vehicular driving. This approach seeks to align licensing guidelines with the specific needs of older drivers, taking into account social, economic, political, and educational aspects, particularly within the Brazilian traffic departments.

Uso dos serviços de saúde por pessoas idosas em áreas rurais e urbanas do Brasil / Health services utilization by older adults in rural and urban areas of Brazil

Resumo Objetivo Avaliar o uso dos serviços de saúde por pessoas idosas residentes em áreas urbanas e rurais do Brasil. Método Estudo transversal que analisou dados da Pesquisa Nacional de Saúde 2019, referentes aos moradores idosos (≥60 anos) selecionados nos domicílios, totalizando 22.728 entrevistas (3.300 em área rural e 19.426 em área urbana). Foram estimadas para as áreas rurais e urbanas as prevalências de cadastro na Estratégia Saúde da Família, intervalo de tempo da última consulta médica e odontológica, procura do serviço nas últimas duas semanas, última aferição da pressão arterial e da glicemia e avaliados os fatores associados à utilização dos serviços de saúde médicos e odontológicos nos últimos 12 meses. Resultados A autopercepção da saúde como 'muito boa' ou 'boa' foi maior na área urbana (47,32%), assim como a proporção de pessoas idosas que relataram consulta médica e odontológica nos últimos 12 meses (90,54%). Evidenciou-se menor frequência do acompanhamento da aferição de pressão arterial (81,30%) e da glicemia (45,83%) em áreas rurais. As pessoas idosas que possuem baixa escolaridade, residem em áreas rurais, na região Norte são as que possuem menor chance de utilização dos serviços. Conclusão A população idosa residente em área rural apresenta piores condições de saúde em relação à população residente em área urbana.

Abstract Objective To assess health services utilization by older adults in urban and rural areas of Brazil. Method A cross-sectional study was conducted analyzing data from the 2019 National Health Survey on older adults (≥60 years) selected from households based on 22,728 interviews (3,300 in rural and 19,426 in urban areas). For rural and urban areas, the prevalence of Family Health Strategy enrolment, time since last medical and dental visit, service use in past 2 weeks, and last blood pressure and blood glucose measurements were estimated. Also, the factors associated with medical and dental health services utilization in the past 12 months were explored. Results Self-rated health of "Very good" or "Good" was greater in urban areas (47.32%), as was the proportion of older adults reporting a medical or dental visit within the last 12 months (90.54%). Rates of blood pressure (81.30%) and glucose (45.83%) monitoring were lower in rural areas. Older individuals that had low education, resided in rural areas, and the North region, had a lower likelihood of using health services Conclusion The older population living in rural areas had poorer health status compared with the urban population.

Caracterización de los adultos mayores con cáncer colorrectal en la comunidad / Characterization of Community Older Adults with Colorectal Cancer

Introducción: El cáncer colorrectal es la neoplasia más frecuente del sistema digestivo en los adultos mayores. En Cuba es un problema de salud de primer orden por su elevada incidencia y mortalidad, que constituye la tercera causa de muerte. Objetivo: Caracterizar a los adultos mayores con cáncer colorrectal en el Policlínico Sur de Sancti Spíritus. Métodos: Investigación de tipo descriptiva en el Policlínico Sur del municipio y la provincia de Sancti Spíritus de enero a marzo del 2019. Muestra intencional de 127 adultos mayores, pertenecientes a consultorios urbanos. Las variables: edad, sexo, escolaridad, estadio del cáncer colorrectal al diagnóstico, estado de salud, comorbilidades, capacidad y percepción del autocuidado y supervivencia. Para determinar el estadio al diagnóstico se utilizó la clasificación anatomoclínica. La comorbilidad se midió mediante el índice de Chalson mientras que para medir la capacidad y percepción del autocuidado se empleó el Test de CYPAC-AM. Resultados: En la caracterización de la muestra predominaron las mujeres, el grupo de edad entre 70 y 79 años y la escolaridad de secundaria básica. El estadio II, con un mal estado de salud y la inadecuada percepción de autocuidado, fue mayoritario. La comorbilidad fue moderada con una supervivencia entre 40 a 60 meses. Conclusiones: La adecuada caracterización de los adultos mayores con cáncer colorrectal en la comunidad posibilita trazar estrategias dirigidas a la mejora del autocuidado y el estado de salud de los gerontes desde el primer nivel de atención(AU)

Introduction: Colorectal cancer is the most frequent neoplasm of the digestive system in older adults. In Cuba, it is a highly significant health problem due to its high incidence and mortality, also being the third cause of death. Objective: To characterize older adults with colorectal cancer at Policlínico Sur of Sancti Spíritus. Methods: A descriptive research was carried out in Policlínico Sur of Sancti Spíritus Municipality and Province from January to March 2019. The intentional sample was made up of 127 older adults, belonging to urban family medical offices. The variables were age, sex, school level, stage of colorectal cancer at diagnosis, health status, comorbidities, selfcare capacity and perception, and survival. The anatomoclinical classification was used to determine the stage at diagnosis. Comorbidity was measured using the Chalson index, while the CYPAC-AM (older adult selfcare capacity and perception) test was used to measure selfcare capacity and perception. Results: In the characterization of the sample, there was a predominance of women, the age group between 70 and 79 years, and the junior high school level. Stage II prevailed, together with poor health status and inadequate selfcare perception. Comorbidity was moderate, with survival between 40 to 60 months. Conclusions: The adequate characterization of older adults with colorectal cancer in the community makes it possible to outline strategies aimed at improving selfcare and their health status from the first level of care(AU)

Nuevos factores de riesgo cardiovascular en el adulto mayor

Introducción: Se han explorado los posibles predictores no tradicionales de enfermedades cardiovasculares en personas mayores. Objetivo: Identificar los factores de riesgo no tradicionales de mortalidad por enfermedades cardiovasculares en adultos mayores. Métodos: Se realizó un estudio analítico de tipo casos y controles en pacientes adultos mayores pertenecientes a 3 áreas de salud del municipio Santiago de Cuba, durante el año 2021. Los casos fueron pacientes fallecidos por enfermedad cardiovascular de tipo ateroesclerótica y los controles, pacientes adultos mayores vivos, sin la enfermedad. Se determinó la razón de productos cruzados (OR), el intervalo de confianza (IC) y la prueba ji cuadrado para identificar los factores de riesgo que se asociaron a la mortalidad. Resultados: La fragilidad (OR= 3,380; IC: 2,476-4,615; p= 0,000) y el deterioro cognitivo (OR= 2,731; IC: 2,006-3,717; p= 0,000] mostraron asociación estadística muy significativa con la mortalidad; los pacientes con 3 o más factores de riesgo presentaron un mayor riesgo de mortalidad (OR= 4,683). Conclusiones: La fragilidad y la multimorbilidad son nuevos predictores de mortalidad por enfermedades cardiovasculares en adultos mayores, que cuando se asocian, implican mayor riesgo.

Introduction: Possible non-traditional predictors of cardiovascular diseases in older people have been explored. Objective: Identify non-traditional risk factors predictive of mortality from cardiovascular diseases in older adults. Method: An analytical case-control study was carried out on older adult patients belonging to 3 health areas of the Santiago de Cuba municipality, during the year 2021. Cases: patients who died due to atherosclerotic cardiovascular disease, and controls, older adult patients alive, without the disease. The cross-product ratio (OR), the confidence interval (CI) and the chi-square test were determined to identify the factors that were associated with the onset of the disease. Results: Frailty (OR= 3.380; CI: 2.476-4.615; p= 0.000) and cognitive impairment (OR= 2.731; CI: 2.006-3.717; p= 0.000) showed a very significant statistical association with mortality; patients with 3 or more risk factors presented a higher risk of mortality (OR= 4.683). Conclusions: Frailty and multimorbidity are new predictors of mortality from cardiovascular diseases in older adults, which when associated imply greater risk.

Idosos privados de liberdade: "a dor deles dói mais" / Older adults deprived of liberty: "their pain hurts more"

Resumo Este ensaio consiste numa reflexão sobre encarceramento de pessoas idosas nos Estados Unidos (EUA) e no Brasil. O objetivo principal é observar em que medida a situação se coaduna e difere nos dois países, sendo que nos EUA a bibliografia sobre o tema é muito mais afluente e consolidada. Entre os estudiosos existem várias discrepâncias entre os dados e entre a visão dos autores. Porém todos convergem quanto: (1) ao aumento do número de pessoas idosas na prisão; (2) à inadequação das prisões para abrigá-los; (3) à aceleração do envelhecimento pela falta de cuidados com a saúde; (4) às vivências de comorbidades físicas, osteomusculares e mentais; e (5) aos elevados custos para tratá-los adequadamente. A maioria dos idosos presos são homens, pobres, negros e pardos e pessoas com determinados tipos de fragilidade social. Um fator positivo apontado tanto por pesquisadores brasileiros como norte-americanos é o cultivo da espiritualidade, o que ajuda as pessoas idosas presas a manterem um certo sentimento de bem-estar. Mas os idosos nas prisões exigem muitos outros cuidados e há poucas iniciativas que levam em conta as necessidades específicas desse seguimento social. Chegou a hora do Brasil enfrentar esta questão, seja por responsabilidade social seja por solidariedade humana.

Abstract This essay reflects on the incarceration of older adults in the United States (USA) and Brazil and mainly aims to observe how the situation is consistent and differs in the two countries. The bibliography on the subject is much more affluent and consolidated in the USA. Several discrepancies are noted among scholars between data and authors' views. However, they all agree regarding (1) the increased number of incarcerated older adults, (2) the inadequacy of prisons to house them, (3) the accelerated aging due to lack of healthcare, (4) the experiences of physical, musculoskeletal, and mental comorbidities, and (5) the high costs of treating them adequately. Most senior prisoners are poor Black and brown men and people with some specific social fragility. A positive factor underscored by Brazilian and North American researchers is the cultivation of spirituality, which helps older adults in prison keep some well-being. However, incarcerated older adults require much other care, and few initiatives consider the specific needs of this social group. The time has come for Brazil to face this issue, whether out of social responsibility or human solidarity.

Efecto de la implementación de programas de gerontología comunitaria sobre el envejecimiento saludable o activo en adultos mayores en México: Revisión sistemática y meta-análisis / Effect of the implementation of community gerontology programs on healthy or active aging in older adults in Mexico: Systematic Review and meta-analysis

Introducción: El incremento de la población de adultos mayores y el aumento de la esperanza de vida han sido determinantes para la incidencia de las enfermedades crónico no trasmisibles en la vejez, lo que conlleva al riesgo de tener una limitación funcional física, psicológica y social. Por tal motivo, la intervención comunitaria para el Envejecimiento Saludable (ES) y Envejecimiento Activo (EA), es una oportunidad para que el adulto mayor mantenga, prolongue o recupere la capacidad funcional (CF), elemento clave del ES Método: se realizó una búsqueda de artículos científicos en las bases de datos PubMed, Scopus, SciELO, LILACS, TESIUNAM. Resultados: Se encontraron 378 artículos (PubMed n=173, Scopus n=95, SciELO n=56, LILACS n=54, TESIUNAM n=17), de los cuales ocho cumplieron los criterios para el análisis cualitativo (revisión sistemática), solo 2 estudios fueron incluidos en el análisis cuantitativo (Meta-análisis). Respecto al MA los parámetros incluidos; concentración sanguínea de glucosa y colesterol (CL)así como en las cifras de presión arterial diastólica (PAD), índice de masa corporal (IMC) y peso. Es así como se encontró una disminución estadísticamente significativa después de la intervención en la concentración sanguínea, TG (-40.91, IC95% -53.90, -27.93 p<0.0001); CL (-19.39, IC95% -30.14, -8.63 p<0.0004) y PAS (-11.21 IC95% -20.29, -2.13 y p<0.02). Conclusiones: Nuestros hallazgos muestran un efecto positivo de los programas de intervención comunitaria de ES y EA, sobre las CF físicas, psicológicas y sociales, aunque existe una alta heterogeneidad en los métodos, tiempo de intervención y parámetros de medición, es a cabo estudios con una metodología similar.

Introduction: The increase in the population of older adults and the increase in life expectancy have been decisive for the incidence of chronic non-communicable diseases in old age, which entails the risk of having a physical, psychological and social functional limitation. For this reason, the community intervention for Healthy Aging (ES) and Active Aging (EA) is an opportunity for the elderly to maintain, prolong or recover functional capacity (FC), a key element of ES Method: a search of scientific articles was carried out in the PubMed, Scopus, SciELO, LILACS, TESIUNAM databases. Results: 378 articles were found (PubMed n=173, Scopus n=95, SciELO n=56, LILACS n=54, TESIUNAM n=17), of which eight met the criteria for qualitative analysis (systematic review), only 2 studies were included in the quantitative analysis (Meta-analysis). Regarding the MA, the parameters included; blood glucose and cholesterol (CL) concentration, as well as diastolic blood pressure (DBP), body mass index (BMI) and weight. This is how a statistically significant decrease was found after the intervention in blood concentration, TG (-40.91, 95% CI -53.90, -27.93 p<0.0001); CL (-19.39, 95%CI -30.14, -8.63 p<0.0004) and PAS (-11.21 95%CI -20.29, -2.13 and p<0.02). Conclusions: Our findings show a positive effect of SE and EA community intervention programs on physical, psychological and social CF, although there is a high heterogeneity in the methods, intervention time and measurement parameters, it is carried out studies with a similar methodology.

Introdução: O aumento da população de idosos e o aumento da esperança de vida têm sido decisivos para a incidência de doenças crónicas não transmissíveis na velhice, o que acarreta o risco de ter uma limitação funcional física, psicológica e social. Por esta razão, a intervenção comunitária para o Envelhecimento Saudável (ES) e o Envelhecimento Ativo (EA) constitui uma oportunidade para os idosos manterem, prolongarem ou recuperarem a capacidade funcional (CF), elemento fundamental do ES. Método: foi realizada busca de artigos científicos nas bases de dados PubMed, Scopus, SciELO, LILACS, TESIUNAM. Resultados: foram encontrados 378 artigos (PubMed n=173, Scopus n=95, SciELO n=56, LILACS n=54, TESIUNAM n=17), dos quais oito atenderam aos critérios de análise qualitativa (revisão sistemática), apenas 2 estudos foram incluídos na análise quantitativa (Meta-análise). Em relação ao MA, os parâmetros incluídos; concentração de glicemia e colesterol (CL), bem como pressão arterial diastólica (PAD), índice de massa corporal (IMC) e peso. Foi assim que foi encontrada uma diminuição estatisticamente significativa após a intervenção na concentração sanguínea, TG (-40,91, IC 95% -53,90, -27,93 p<0,0001); CL (-19,39, IC95% -30,14, -8,63 p<0,0004) e PAS (-11,21 IC95% -20,29, -2,13 e p<0,02). Conclusões: Nossos resultados mostram um efeito positivo dos programas de intervenção comunitária de SE e EA na FC física, psicológica e social, embora haja uma alta heterogeneidade nos métodos, tempo de intervenção e parâmetros de medição, são realizados estudos com metodologia semelhante.

"Minha vida é me cuidar": itinerários terapêuticos de cuidado para a pessoa idosa em processo de fragilização / "My life is about to take care of myself": therapeutic itineraries of care for frail older adults

Resumo O trabalho buscou compreender a percepção de pessoas idosas em processo de fragilização sobre seus itinerários terapêuticos de cuidados. Esta pesquisa qualitativa, ancorou-se na antropologia médica crítica. A coleta dos dados ocorreu por meio de entrevistas no domicílio de 22 pessoas idosas, com média etária de 79 anos. A análise êmica foi guiada pelo modelo dos signos, significados e ações. Todos os(as) entrevistados(as) expressam acessar cuidados profissionais em sua trajetória que são interpretados como: insuficientes, despreparados, preconceituosos, incômodos, contraditórios, (in)acessíveis, um achado, respeitosos e excessivos. Os itinerários terapêuticos revelam-se também nos âmbitos psicossociais e culturais. Diversas ações do dia a dia vão sendo avaliadas e interpretadas no registro do cuidado consigo e justificadas por esse fim: o horário que acorda, que dorme, o que come, como se comporta. Em suas trajetórias, deparam-se com a falta de políticas de cuidados, com o enquadramento de seus corpos como indesejáveis, com barreiras físicas, simbólicas, comunicacionais, atitudinais, sistemáticas, culturais e políticas. Desse modo, revelam o pluralismo terapêutico, os desafios, os enfrentamentos, a insistência e a resistência na manutenção de cuidados ao experienciar velhices com fragilidades.

Abstract The present study sought to understand how frail older adults perceive their therapeutic care itineraries. This qualitative research was based on Critical Medical Anthropology. Data were collected through interviews in the homes of 22 older adults, whose average age was 79. The emic analysis was guided by the model of Signs, Meanings, and Actions. All interviewees expressed access to professional care in their trajectories, which are understood as insufficient, unprepared, prejudiced, uncomfortable, contradictory, (un)accessible, realization, respectful, and excessive. Therapeutic itineraries were also revealed in the psychosocial and cultural spheres. Several day-to-day actions were evaluated and interpreted in the record of self-care and justified by this end: the time they wake up, sleep, what they eat, and how they behave. They face the lack of care policies in their trajectories, labeling their bodies as undesirable due to physical, symbolic, communicational, attitudinal, systematic, cultural, and political barriers. Thus, they bring to light therapeutic pluralism, challenges, confrontations, insistence, and resistance in maintaining care when experiencing old age with frailties.

Algunas especificidades concernientes a las complicaciones quirúrgicas infecciosas en adultos mayores tras cirugía abdominal de urgencia / Specificities Concerning Infectious Surgical Complications in Older Adults after Emergency Abdominal Surgery

Introducción: El manejo del paciente geriátrico en cirugía siempre ha representado un gran desafío por considerarse de "alto riesgo". Objetivo: Describir las características clínicas, terapéuticas y epidemiológicas concernientes a las complicaciones quirúrgicas infecciosas en adultos mayores tras cirugía abdominal de urgencia. Métodos: Se realizó un estudio observacional analítico de casos y controles en pacientes adultos mayores que presentaron complicaciones quirúrgicas tras cirugía abdominal de urgencia en el período comprendido de 2019 hasta 2021 en el Servicio de Cirugía General del Hospital Provincial Saturnino Lora de Santiago de Cuba. Se trabajó con una muestra de casos complicados y otra de controles, representada por aquellos que no sufrieron complicaciones. Las variables analizadas fueron: edad, sexo, comorbilidades gérmenes aislados y tratamiento requerido. Resultados: Las complicaciones quirúrgicas en la cirugía abdominal urgente afectan fundamentalmente a pacientes adultos mayores en edades tempranas de ambos sexos con antecedentes de enfermedades endocrinas y/o cardiovasculares. La infección superficial y profunda del sitio quirúrgico es la complicación predominante. Los gérmenes más frecuentemente aislados fueron: Escherichia coli, Pseudomona aureoginosa y Klebsiella. El tratamiento farmacológico seguido del quirúrgico se utilizó en la mayoría de los enfermos para la solución de sus complicaciones. Conclusiones: Las comorbilidades constituyen el factor de riesgo principal para la aparición de complicaciones quirúrgicas infecciosas en adultos mayores, tras cirugía abdominal de urgencia con primacía de la infección superficial y profunda del sitio quirúrgico. Los gérmenes causales están en relación con la microbiota de la piel, donde se realiza la incisión, y la microbiota de los órganos donde se efectúa la intervención quirúrgica(AU)

Introduction: The surgical management of the geriatric patient has always represented a great challenge because such is considered as "high risk." Objective: To describe the clinical, therapeutic and epidemiological characteristics concerning infectious surgical complications in older adults after emergency abdominal surgery. Methods: An analytical observational study of cases and controls was carried out with older adult patients who presented surgical complications after emergency abdominal surgery, in the period from 2019 to 2021, at the general surgery service of Hospital Provincial Saturnino Lora, of Santiago de Cuba. The study work was conducted with a sample of complicated cases and another sample of controls, the latter represented by those who did not suffer complications. The analyzed variables were age, sex, comorbidity, isolated germs and required treatment. Results: Surgical complications in emergency abdominal surgery affect mainly older adult patients at early ages, from both sexes and with a history of endocrine or cardiovascular diseases. Superficial and deep surgical-site infection is the predominant complication. The most frequently isolated germs were Escherichia coli, Pseudomona aureoginosa and Klebsiella. Pharmacological treatment followed by surgical treatment was used in most of the patients, with the aim of giving a solution to their complications. Conclusions: Comorbidity is the main risk factor for the appearance of infectious surgical complications in older adults after emergency abdominal surgery, primarily for superficial and deep surgical-site infection. The causal germs are related to the skin microbiota, according to the site where the incision is made, as well as the microbiota of the organs where the surgical intervention is performed(AU)

Design of Exercise Device for Older Adults / Diseño de Dispositivo para Ejercitación de Adultos Mayores

ABSTRACT Older adults should perform physical activity to improve cardiorespiratory functions. Aerobic exercises improve cardiovascular function, decrease basal heart rate and blood pressure, and improve mood and energy. To facilitate the execution of aerobic physical activity in older adults, the objective of this research was to design an exercise device for older adults. Starting from design specifications such as comfort, size, weight, resistance, and cost, we developed the detailed design of a horizontal bicycle. The designed device, thanks to its horizontally disposed structure, its adequate resistance to pedaling, its dimensioning based on anthropometric measurements of the Chilean population, and the disposition of sensors for heart rate and oxygen saturation, is suitable for older adults. Its weight and size also make it convenient for use inside the home, and the use of materials, components, and manufacturing processes available nationally and within the cheapest options, increases the possibility of access by older adults.

RESUMEN Es fundamental que los adultos mayores realicen actividad física para mejorar las funciones cardiorrespiratorias, particularmente los ejercicios aeróbicos mejoran la función cardiovascular, disminuyen la frecuencia cardíaca basal y la tensión arterial, además de mejorar su estado de ánimo y energía. Con la finalidad de facilitar la ejecución de actividad física del tipo aeróbica en adultos mayores, se planteó el objetivo de este trabajo, centrado en diseñar un dispositivo para su ejercitación. Partiendo de especificaciones de diseño como comodidad, tamaño, peso, resistencia y costo, se desarrolló el diseño de detalle de una bicicleta horizontal. El dispositivo diseñado, gracias a la disposición horizontal de la estructura, la resistencia adecuada al pedaleo, su dimensionamiento con base a medidas antropométricas de población chilena, y la disposición de sensores para heart rate and oxygen saturation, es adecuado para adultos mayores. Además, su peso y tamaño lo hacen conveniente para el uso dentro de las viviendas, del mismo modo, el uso de los materiales, componentes y proceso de manufactura disponibles nacionalmente y dentro de las opciones más económicas, aumentan la posibilidad de acceso por parte de los adultos mayores.

RESUMO: Objetivo: analisar a distribuição espacial da violência contra a pessoa idosa na região Sul do Brasil antes e no primeiro ano de vigência da pandemia de COVID-19. Método: estudo ecológico que analisou as notificações de violência contra o idoso, entre 2019 e 2020, no Sul do Brasil. Foram calculadas as taxas bayesianas empíricas locais, o Índice de Autocorrelação Local de Moran e a análise de Getis Ord Gi. Resultados: houve redução da taxa suavizada de violência contra o idoso. As cidades alto-alto e hot-spot em 2019, se tornaram mais violentas em 2020; e as cidades com baixa prevalência, se tornaram menos violentas em 2020. As maiores taxas de letalidade por COVID-19 também foram naquelas cidades com maiores taxas de violência. Conclusão: os dados reforçam a complexidade da violência e seu agravamento pela pandemia. E contribuem com as tomadas de decisões na enfermagem, desatacando-se a necessidade de suscitar novas pesquisas sobre esta temática.

ABSTRACT Objective: to analyze the spatial distribution of violence against older adults in the Brazilian South region before and in the first year of the COVID-19 pandemic. Method: an ecological study that analyzed reports of violence against older adults between 2019 and 2020, in Southern Brazil. Local empirical Bayesian rates, Moran's Local Autocorrelation Index and Getis Ord Gi analysis were calculated. Results: there was a reduction in the smoothed rate of violence against older adults. The high-high and hot-spot cities in 2019 became more violent in 2020; and cities with low prevalence became less violent in 2020. The highest COVID-19 fatality rates were also in those cities with the highest violence rates. Conclusion: the data reinforces the complexity of violence and its worsening due to the pandemic. In addition, they contribute to decision-making in Nursing, highlighting the need to encourage new research studies on this theme.

Correlation between intrinsic capacity and activities of daily living for old adults in China: based on China Health and Retirement Longitudinal Study / 中国康复理论与实践

ObjectiveTo explore the weights and comprehensive indices of each field of intrinsic capacity of old adults, and the correlation between intrinsic capacity and activities of daily living (ADL). MethodsThe data of 5 506 cases aged more than 60 years in the 2015 China Health and Retirement Longitudinal Study (CHARLS) were used to collect the assessment of intrinsic capacity and the measurement of ADL. The assessment of intrinsic capacity included cognition, motor, vitality, sensory and psychology; while the ADL scale included six indicators, namely dressing, bathing, eating, getting in or out of bed, going to the toilet, and controlling urine and feces. ResultsA total of 1 343 cases were limited in ADL (24.4%). Women, lower education level, older age, the widowed, greater number of chronic diseases, and poorer self-rated health were the factors more likely to be limited in ADL. Principal component analysis showed that the largest weight value was in psychological domain, followed by the cognitive domain, and the lowest weight value was in the motor domain. After controlling for the effects of age, gender, living environment, economic income, education level, marriage, smoking and drinking, number of chronic diseases, and self-rated health, the Logistic regression analysis showed that low exercise capacity (OR = 0.581, 95%CI 0.501 to 0.674), depression (OR = 0.426, 95%CI 0.368 to 0.493), audile and visual impairment (OR = 0.813, 95%CI 0.699 to 0.947; OR = 0.684, 95%CI 0.578 to 0.809), overweight (OR = 1.203, 95%CI 1.014 to 1.428) and obesity (OR = 1.584, 95%CI 1.312 to 1.912) were independent risk factors for ADL limitation in older adults. ConclusionDecrease of intrinsic capacity is a predictor for ADL limitation in older adults.

Construction of a hypoglycemia prediction model for older adults with type 2 diabetes based on random forest algorithm / 中国实用护理杂志

Objective:To construct a hypoglycemia random forest prediction model for older adults with type 2 diabetes, and assess the model′s prognostication performance through internal and external verification.Methods:From August 2022 to January 2023, 300 older adults with type 2 diabetes in Beijing Hospital were selected. The demographic characteristics, medical history, laboratory tests, and other data of the patients were collected, and the data set was randomly divided into the training set and verification set in a ratio of 7∶3. The hypoglycemia prediction model for older adults with type 2 diabetes was constructed and optimized based on the random forest algorithm. The calibration curve was used to evaluate the model′s calibration, and the ROC was used to evaluate the model′s discrimination. The clinical applicability of the model was assessed by the decision curve analysis. The risk factors for hypoglycemia in the older adults were explored by prioritizing the contributions of variables in prediction. The Bootstrap method was used for internal validation, and the validation set was used for external validation.Results:Among the 300 older adults with type 2 diabetes, 128 cases (42.67%) experienced hypoglycemia within one week. The predictive contributions of risk factors in the model were ranked as follows: the number of episodes of hypoglycemia in one month, HDL-C, heart disease, diabetes knowledge and education, combination therapy, age, duration of diabetes, staple food restriction, glycosylated hemoglobin, and gender. The internal and external calibration curves of the hypoglycemia random forest model for the older adults with type 2 diabetes fluctuated around the diagonal, indicating that the calibration degree of the predictive model is good. The AUROC of internal verification was 0.823 (95% CI 0.752-0.894), the sensitivity and specificity were 0.867 and 0.698, respectively. The external verification was 0.859 (95% CI 0.817 - 0.902), and sensitivity and specificity were 0.789 and 0.804, respectively, showing that the overall discrimination of the prediction model was good. The DCA curves were far from the all-positive line and all-negative line, which indicated that the prediction model had good clinical applicability. Conclusions:The predictive effect of this model is good, and it is suitable for predicting the risk of hypoglycemia in older adults with type 2 diabetes, and it provides a reference for early hypoglycemia screening and predictive intervention for this kind of patients.
