Use of potentially inappropriate medications and medications of concern in older adults with multiple myeloma / Utilização de medicamentos potencialmente inapropriados e medicamentos que requerem cautela em idosos com mieloma múltiplo

Objetivo: Analisar o uso de medicamentos potencialmente inapropriados (MPIs) e o uso de medicamentos usados em terapia de suporte que requerem cautela em idosos com câncer (MTSRCICs), determinando os fatores associados. Visou-se também determinar a concordância entre os critérios explícitos empregados na identificação de MPI. Metodologia: Estudo transversal com indivíduos com mieloma múltiplo (MM), idade ≥ 60 anos em tratamento ambulatorial. Os MPI foram identificados de acordo com os critérios AGS Beers 2019, PRISCUS 2.0 e o Consenso Brasileiro de Medicamentos Potencialmente Inapropriados (CBMPI). Os MTSRCIC foram definidos de acordo com a National Comprehensive Cancer Network. Os fatores associados ao uso de MPI e MTSRCIC foram identificados por regressão logística múltipla. O grau de concordância entre os três critérios explícitos empregados no estudo foi mensurado pelo coeficiente kappa Cohen. Resultados: As frequências de MPI foram 52,29% (AGS Beers 2019), 62,74% (CBMPI), 65,36% (PRISCUS 2.0) e 52,29% (MTSRCICs). As concordâncias entre AGS Beers 2019 com PRISCUS 2,0 e com CBMPI foram altas, enquanto a concordância entre CBMPI e PRISCUS 2.0 foi excelente. No modelo final de regressão logística polifarmácia foi associada positivamente ao uso de MPI por idosos para os três critérios explícitos utilizados, além de associado à utilização de MTSRCICs. Conclusões: A frequência do uso de MPI e de MTSRCIC foi elevada. A concordância em relação ao uso de MPI entre os critérios AGS Beers 2019, CBMPI e PRISCUS 2.0 foi alta ou excelente. A polifarmácia apresentou associação independente e positiva com uso de MPIs e de MTSRCICs por pacientes idosos com MM. (AU)

Objectives: To analyze the use of potentially inappropriate medications (PIMs) and medications used in supportive therapy that require caution in older adults with cancer, in addition to determining associated factors the agreement between criteria sets used to identify PIMs. Methods: This cross-sectional study included individuals with multiple myeloma aged ≥ 60 years who were undergoing outpatient treatment. PIMs were identified according to American Geriatric Society Beers 2019, PRISCUS 2.0, and Brazilian Consensus on Potentially Inappropriate Medicines criteria. Medications of concern were defined according to National Comprehensive Cancer Network criteria. Factors associated with the use of PIMs and medications of concern were identified using multiple logistic regression. The degree of agreement between the 3 criteria sets was measured using Cohen's kappa coefficient. Results: The frequency of PIM use was 52.29% according to American Geriatric Society Beers criteria, 62.74% according to Brazilian Consensus criteria, and 65.36% according to PRISCUS criteria, while 52.29% of the patients were using medications of concern. Agreement between American Geriatric Society Beers, PRISCUS, and Brazilian Consensus criteria was high, while it was excellent between Brazilian Consensus and PRISCUS criteria. In the final logistic regression model, polypharmacy was associated with PIM use according to each criteria set, as well as the use of medications of concern. Conclusions: The frequency of PIMs and medications of concern was high. Agreement about PIM use between the American Geriatric Society Beers, Brazilian Consensus, and PRISCUS criteria was high or excellent. There was an independent association between polypharmacy and the use of PIMs and medications of concern by older patients with multiple myeloma. (AU)

Physical activity, protein consumption, and loss of muscle mass in older adult participants of the ELSA-Brazil study / Atividade física, consumo de proteínas e perda de massa muscular em idosos do ELSA-Brasil

Objetivo: Objetiva-se avaliar a relação entre consumo de proteínas (CP), atividade física (AF) e massa muscular (MM) em indivíduos com 60 anos ou mais de idade. Metodologia: Trata-se de um estudo prospectivo a partir da linha de base e segunda onda do estudo ELSA-Brasil. O CP foi avaliado por meio de um questionário de frequência alimentar semiquantitativo (QFA). A AF foi mensurada pelo International Physical Activity Questionnaire (IPAQ). A MM foi estimada por meio de equação de predição, e calculada a diferença de MM entre a 2a e a 1a onda. Análises bivariadas foram realizadas adotando o valor de p < 0,05. Para as análises multivariadas, utilizou-se a regressão de Poisson, com quatro modelos distintos, que incluíram as covariáveis com valor de p < 0,20. Utilizou-se o pacote estatístico SPSS versão 21. Resultados: A amostra foi constituída de 2216 idosos, sendo 55,10% de mulheres, com média de idade de 65,20 ± 4,15. Indivíduos com redução de MM entre as duas ondas estão situados no primeiro quartil de consumo de proteína. Além disso, a média de AF mostrou diferença significativa entre os grupos e a AF no lazer apenas para as mulheres (p < 0,05). Após ajuste por variáveis sociodemográficas, de saúde e hábitos de vida, indivíduos com menor consumo de proteínas apresentaram risco de 1,45 (1,29 ­ 1,63) de apresentar MM diminuída. Conclusões: O menor CP e AF forte estão associados à MM diminuída, e aqueles com menor CP no primeiro e segundo quartis apresentam maior risco de possuir MM diminuída. (AU)

Objective: The objective was to evaluate the relationship between protein consumption, physical activity, and muscle mass in individuals aged ≥ 60 years. Methods: This prospective study was based on the baseline and second wave of the ELSA Brazil study. Protein consumption was assessed using a semiquantitative food frequency questionnaire. Physical activity was measured using the International Physical Activity Questionnaire. Muscle mass was estimated using a prediction equation, and the difference in MM between the first and second waves was calculated. Bivariate analyses were performed, with p < 0.05 considered significant. Multivariate analysis consisted of 4 Poisson regression models including covariates with p < 0.20. The statistical analysis was performed in IBM SPSS Statistics 21. Results: The sample included 2216 older adults, 55.10% of whom were women, with a mean age of 65.20 (SD, 4.15). Participants whose muscle mass decreased between the waves were in the first quartile of protein consumption. Mean physical activity significantly differed between the groups, while leisure-time physical activity differed only for women (p < 0.05). After adjusting for sociodemographic, health, and lifestyle variables, participants with lower protein intake had a 1.45 (1.29­1.63) relative risk of muscle mass loss. Conclusions: Lower protein consumption and higher physical activity were associated with decreased muscle mass, and those with protein consumption in the first and second quartiles are at higher risk of muscle mass loss.

Efeitos do treinamento multicomponente na capacidade intrínseca de idosos residentes na comunidade: protocolo de estudo quase-experimental / Effects of multicomponent training on the intrinsic capacity of communitydwelling older adults: quasi-experimental study protocol

Objetivo: Protocolo para avaliar os efeitos de exercícios multicomponentes na capacidade intrínseca de idosos. Metodologia: Pessoas idosas (≥ 60 anos) cadastradas em um programa de treinamento multicomponente de Porto Alegre (RS) serão selecionados para avaliação da capacidade intrínseca nos seus cinco domínios: vitalidade (teste de força de preensão manual (FPM), índice de massa corpórea (IMC) e nutrição) sensorial (perguntas autorrelatadas), psicológico (Escala de Depressão Geriátrica, GDS-15), cognitivo (MoCA teste) e locomotor (teste de sentar e levantar e TUG). A pontuação composta da capacidade intrínseca será realizada por meio da soma dos domínios em escore de 0 a 10 pontos. Ao fim de 12 semanas de intervenção com exercícios multicomponentes, os participantes serão reavaliados. Para comparar os efeitos do treinamento multicomponente na capacidade intrínseca composta e por domínio serão utilizados os testes t de Student e ANOVA para comparar os efeitos de diversos tipos de treinamento. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa sob parecer no 5.517.315. Resultados esperados: Ao fim de 12 semanas de intervenção com os exercícios multicomponentes, esperamos um aumento na pontuação composta da capacidade intrínseca e em seus domínios, especialmente o locomotor. Relevância: O risco de dependência, quedas e mortalidade aumenta com o declínio da capacidade intrínseca, suscitando a necessidade de implementar intervenções para limitar esses desfechos negativos. A prática de exercícios multicomponentes é uma estratégia simples, eficaz, com boa adesão e amplamente recomendada para evitar o declínio da capacidade intrínseca e melhorar a saúde e a funcionalidade das pessoas idosas. (AU)

Objective: This is a protocol for assessing the effects of multicomponent exercise on the intrinsic capacity of older adults. Methods: Older adults (≥ 60 years old) will be selected for a multicomponent training program in Porto Alegre, RS, Brazil to evaluate the 5 domains of intrinsic capacity: vitality (handgrip strength, body mass index, and nutrition) sensory perception (self-reported questions), psychology (the 15-item Geriatric Depression Scale), cognition (the Montreal Cognitive Assessment) and locomotion (the sit-to-stand test and the Timed Up and Go test). The composite intrinsic capacity score will be obtained by summing the domains, with total scores ranging from 0 to 10 points. After 12 weeks of the multicomponent exercise intervention, the participants will be reassessed. Student's t-test and ANOVA will be used to compare the effects of different types of training on intrinsic capacity. This study was approved by the research ethics committee of the involved institution. Expected results: After the 12-week multicomponent exercise intervention, we expect scores for composite intrinsic capacity and its domains, especially locomotion, to increase. Relevance: The risk of dependence, falls, and mortality increases with reduced intrinsic capacity, indicating a need for interventions to limit these negative outcomes. Multicomponent exercise, a simple, widely recommended, and effective strategy with good adherence, is designed to prevent intrinsic capacity decline in older people and improve their health and functionality.

Interacciones potenciales entre productos herbolarios con fármacos hipoglucemiantes en adultos mayores con diabetes mellitus, en una zona rural mexicana / Potenciais interacções entre produtos à base de plantas e medicamentos hipoglicemiantes em adultos mais velhos com diabetes mellitus no Mexico rural / Potential interactions between herbal products with hypoglycemic drugs in older adults with diabetes mellitus in rural Mexico

Introducción: El 50% de la población mundial usa tratamientos alternativos como productos herbarios. El 20% los consume de manera simultánea con algún tratamiento farmacológico para el control la Diabetes Mellitus tipo 2; enfermedad prevalente en adultos mayores. Es escasa la información acerca de las interacciones medicamentosas que pudieran producirse, siendo responsables de más de 7,000 muertes al año. Objetivo: Identificar los productos herbarios de mayor consumo del Adulto Mayor con Diabetes Mellitus Tipo 2, en Chapulco, Puebla, México y describir las posibles interacciones medicamentosas entre fármaco hipoglucemiante ­ producto herbario reportados en la literatura científica. Metodología: Estudio observacional, prolectivo, transversal, descriptivo, en una población de 35 adultos mayores diabéticos, con edad promedio de 70±7 años. Para la identificación de los productos herbarios de uso común y sus aplicaciones terapéuticas se aplicó el cuestionario U-PLANMED. Resultados: Se identificaron 50 productos herbarios y 18 combinaciones entre estos a la vez. El 40% de los participantes consumen simultáneamente más de dos productos herbarios con uno o dos fármacos hipoglucemiantes. Entre los productos de mayor consumo se encuentran el nopal (Opuntia ficus-indica L.), la manzanilla (Matricaria chamomilla L.) y el zacate de limón (Cymbopogon citratus DC. Stapf.). Las interacciones medicamentosas potenciales identificadas, principalmente en estudios experimentales en animales, sugieren que, existe una acción hipoglucemiante del producto herbario al aumentar la capacidad orgánica sobre la secreción/liberación de insulina endógena. Conclusiones: Se ha evidenciado la presencia de interacciones medicamentosas ante el consumo simultaneo de fármacos prescritos para el control de la diabetes mellitus tipo 2 con productos herbarios. Es necesario que, los profesionales en atención a la salud identifiquen el uso de dichos productos y orienten a los adultos mayores sobre las posibles repercusiones en los niveles de glucosa ante el consumo.

Introduction: 50% of the world's population uses alternative treatments such as herbal products. Twenty percent use them in conjunction with some form of pharmacological treatment to control type 2 diabetes mellitus, a disease prevalent in older adults. There is little information on the drug interactions that may occur, which are responsible for more than 7,000 deaths per year. Objective: To identify the most consumed herbal products among older adults with type 2 diabetes mellitus in Chapulco, Puebla, Mexico, and to describe the possible drug-drug interactions between hypoglycemic drugs and herbal products reported in the scientific literature. Methodology: Observational, prospective, cross-sectional, descriptive study in a population of 35 diabetic older adults with a mean age of 70±7 years. The U-PLANMED questionnaire was used to identify commonly used herbal products and their therapeutic applications. Results: Fifty herbal products and 18 combinations of them were identified. Forty percent of the participants used more than two herbal products simultaneously with one or two hypoglycemic drugs. The most used products included prickly pear cactus (Opuntia ficus-indica L.), chamomile (Matricaria chamomilla L.), and lemon grass (Cymbopogon citratus DC. Stapf.). Potential drug-drug interactions identified mainly in experimental animal studies suggest that there is a hypoglycemic effect of the herbal product by increasing the organic capacity on endogenous insulin secretion/release. Conclusions: The presence of drug-drug interactions has been demonstrated with the simultaneous consumption of drugs prescribed for the control of type 2 diabetes mellitus with herbal products. It is necessary for health care professionals to recognize the use of such products and to inform older adults about the possible repercussions on glucose levels when consuming them.

Introdução: 50% da população mundial utiliza tratamentos alternativos como os produtos à base de plantas. Vinte por cento utilizam-nos em conjunto com algum tipo de tratamento farmacológico para controlar a diabetes mellitus tipo 2, uma doença prevalente em adultos mais velhos. Há pouca informação sobre as interacções medicamentosas que podem ocorrer e que são responsáveis por mais de 7.000 mortes por ano. Objetivos: Identificar os produtos fitoterápicos mais consumidos entre os idosos com diabetes mellitus tipo 2 em Chapulco, Puebla, México, e descrever as possíveis interações medicamentosas entre medicamentos hipoglicemiantes e produtos fitoterápicos relatados na literatura científica. Metodologia: Estudo observacional, prospetivo, transversal e descritivo numa população de 35 idosos diabéticos com uma idade média de 70±7 anos. O questionário U-PLANMED foi utilizado para identificar os produtos fitoterápicos mais utilizados e suas aplicações terapêuticas. Resultados: Foram identificados 50 produtos à base de plantas e 18 combinações dos mesmos. Quarenta por cento dos participantes utilizaram mais de dois produtos à base de plantas em simultâneo com um ou dois medicamentos hipoglicemiantes. Os produtos mais utilizados foram o cato de figo da Índia (Opuntia ficus-indica L.), a camomila (Matricaria chamomilla L.) e o capim-limão (Cymbopogon citratus DC. Stapf.). As potenciais interacções medicamentosas identificadas principalmente em estudos experimentais em animais sugerem que existe um efeito hipoglicémico do produto à base de plantas através do aumento da capacidade orgânica na secreção/libertação de insulina endógena. Conclusões: A presença de interacções medicamentosas foi demonstrada com o consumo simultâneo de medicamentos prescritos para o controlo da diabetes mellitus tipo 2 com produtos à base de plantas. É necessário que os profissionais de saúde reconheçam o uso de tais produtos e informem os idosos sobre as possíveis repercussões nos níveis de glicose ao consumi-los.

Prevalence and risk factors for falls among older Chinese adults in the community: findings from the CLHLS study

Older adults have a high prevalence of falls due to a decline in physiological functions and various chronic diseases. This study aimed to investigate the prevalence of and risk factors for falls among older individuals in the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We collected information from 9737 older individuals (average age=84.26 years) from the CLHLS and used binary logistic regression analysis to explore the independent risk factors and protective factors for falls. The logistic regression analysis results are reported as adjusted odds ratios (aORs) and 95% confidence intervals (95%CIs). The prevalence of falls among older adults in China was 21.6%, with women (24.6%) having a higher prevalence than men (18.1%). Logistic regression analysis revealed that never (or rarely) eating fresh fruit, difficulty with hearing, cataracts, and arthritis were the common independent risk factors for falls in older Chinese men and women. Among men, age ≥80 years (aOR=1.86), never doing housework (aOR=1.36), and dyslipidemia (aOR=1.47) were risk factors, while eating milk products once a week was a protective factor. Alcohol consumption (aOR=1.40), physical labor (aOR=1.28), and heart disease (aOR=1.21) were risk factors for falls in women, while a daily sleep duration of 6-12 h and garlic consumption once a week were protective factors. The prevalence of falls among older adults in China is 21.6% and is greater in women than in men. These risk and protective factors can be used to formulate reasonable recommendations for living habits, diet, and chronic disease control strategies.

Asociación entre la depresión y variables sociodemográficas en el adulto mayor en el Perú / Association between Depression and Sociodemographic Variables in the Elderly in Peru / Associação entre depressão e variáveis sociodemográficas em idosos no Peru

Materials and methods: A cross-sectional, descriptive, and correlational study was conducted, including 5,247 older adults. The data was extracted from the 2019 Demographic and Health Survey (endes) using the Patient Health Questionnaire (phq-9) of nine questions. The health questionnaires also included sociodemographic variables, household characteristics, and housing-related questions. A multiple logistic regression model was used to determine if there was an association between depression and sociodemographic variables. Results: Approximately 15.3% of older adults had a history of depression (moderate, moderately severe, and severe). We identified a relationship between depression and some sociodemographic variables (education level, diabetes, wealth index, sex, and age group). However, depres-sion was not related to smoking habits, obesity, having a partner, and place of residence. Conclusions: Depression was related to some of the sociodemographic variables considered in this study. Depression in older adults is becoming a significant public health problem, more frequent in women, advanced ages, rural areas, low socioeconomic levels, lower educational levels, blood pressure, disability, and problem-atic alcohol consumption. These conditions must be considered in the implementation of public policies

Resultados: os resultados indicam que 15,3 por cento das pessoas com 60 anos ou mais apresentam um nível de depressão moderada, moderadamente grave e grave. Da mesma forma, verificou-se que a depressão e as variáveis sociodemográficas (escolaridade, diabetes, índice de riqueza, sexo e faixa etária) estão relacionadas; entretanto, não estão relacionados com as variáveis hábito de fumar, obesidade, ter companheiro e local de residência. Conclusões: a depressão está relacionada com algumas das variáveis sociodemográficas consideradas neste estudo. A depressão em idosos está se tornando um problema sig-nificativo de saúde pública, mais frequente em mulheres, idades avançadas, áreas rurais, níveis socioeco-nómicos baixos, níveis educacionais mais baixos, pressão arterial, deficiência e consumo problemático de álcool; condições que devem ser levadas em conta para a implementação de políticas públicas.

Relationship between muscle activation characterization and fall risk in older adults during walking up and down stairs / 中国组织工程研究

BACKGROUND:During stair walking,different muscles work in concert and compensate for each other,and it is unclear whether weakened muscle strength actually affects stair fall risk in older adults.Real-time electromyographic signals from older adults during stair walking are used to reflect high fall risk in older adults during stair walking,which may further improve the accuracy of prediction methods. OBJECTIVE:To investigate the effects of aging on lower limb muscle activation in older adults during stair walking and to analyze the relationship between their muscle activation characteristics and stair fall risk. METHODS:Subjects were divided by age into an older group(n=19)and a younger group(n=18)group and were asked to walk on a 10-step staircase at a natural speed,incorporating surface electromyography acquisition technology,to capture surface electromyography signals during stair walking and calculate the root mean square(RMS)to analyze differences in muscle activation levels.Logistic regression analysis was utilized to establish a predictive model for stair fall risk in older adults by incorporating the lateral femoral and gastrocnemius muscle RMS.The discrimination of the model was evaluated by the receiver operating characteristic curve and area under the curve,and the fit of the model was evaluated using the Hosmer-Lemeshow test RESULTS AND CONCLUSION:Activation of the rectus femoris(Z=-3.464,P=0.001;t=3.379,P=0.002)and lateral gastrocnemius muscle(Z=-2.978,P=0.003;Z=-3.555,P<0.001)was higher in older adults than in younger adults when walking up and down stairs.Activation of the anterior tibialis(Z=-2.350,P=0.019)and medial(Z=2.321,P=0.020)and lateral(t=3.158,P=0.004)gastrocnemius muscles was higher in older adults when ascending stairs than descending stairs.Older adults at risk for falls had less activation of the lateral femoral muscle(Z=-2.613,P=0.009),medial gastrocnemius muscle(Z=-2.286,P=0.022)when walking upstairs,and lateral femoral muscle(Z=-2.368,P=0.018)when walking downstairs than did older adults not at risk for falls.The predictive ability,goodness of fit,and discrimination of the stair fall prediction model for older adults based on surface electromyography were good(P-value of 0.010 for the Omnibus test of the model coefficients,P-value of 0.214 for the Hosmer-Lemeshow test,and the area of the curve of the upper staircase lateral femoral muscle=0.856,P=0.009).(5)The model was modeled with a cut-off value of 38.64 for the upper staircase lateral femoral muscle RMS value and there was a 0.952-fold increase in the risk of staircase falls for each unit decrease in the upper staircase lateral femoral muscle RMS in older adults.

Exercise intervention methods for senile sarcopenia / 中国组织工程研究

BACKGROUND:Sarcopenia refers to age-related progressive,systemic muscle mass reduction and/or muscle strength decline or muscle physiological function decline,which is related to the occurrence of a variety of adverse outcomes in older adults.Exercise is considered to be one of the main strategies for combating sarcopenia in older adults,but there is a lack of specific intervention methods of different exercise patterns to intervene in sarcopenia. OBJECTIVE:To elaborate the main influencing factors of sarcopenia and the research progress of different exercise methods to improve sarcopenia in older adults,providing reference and basis for combating sarcopenia in older adults. METHODS:Web of Science,PubMed,CNKI,VIP,WanFang databases were retrieved for relevant literature published from January 2000 to October 2023 using the keywords of"sarcopenia,sport,exercise intervention,resistant training,aerobic exercise,whole body vibration training,mixed training,physical performance,muscle strength,muscle mass"in Chinese and English,respectively.A total of 126 articles were included for review. RESULTS AND CONCLUSION:Resistance exercise is still the most effective way to prevent and treat senile sarcopenia,and the effect of high-intensity resistance exercise is more significant.However,in practical application,we should pay attention to the gradual increase of training load intensity.Aerobic exercise combined with resistance exercise is more effective to improve muscle mass and function in the elderly than a single exercise mode.It is suggested that older adults can carry out the transition of low-intensity aerobic exercise in the early stage and increase resistance exercise individually in the late stage.Whole body vibration training is a new treatment method for the prevention and treatment of senile sarcopenia,but particular attention should be paid to the effects of frequency,amplitude,and duration on patients during practical application.Multicomponent exercise combines different exercise modes,which can give full play to their respective advantages,so as to personalize exercise interventions.

Research Progress on Changes of Lower Limb Stiffness in Older Adults During Ageing / 医用生物力学

Walking downstairs and running are common actions in daily life;however,older adults with functional decline are prone to falls or injuries.To cope with various situations and avoid falls,the first neuroprotective motor mechanism activated by the body is the regulation of lower limb stiffness.Hence,this study retrieved and collected relevant research results from databases such as China Knowledge,Wanfang,Google Scholar,and Web of Science,using key words such as elderly and lower limb stiffness,and summarized the similarities and differences in changes in lower limb stiffness in different action tasks.The findings show that interventions on controllable factors can improve changes in lower limb stiffness to prevent falls in older adults.However,owing to the small number of related studies,it is necessary to further investigate the effects of action interventions on lower limb stiffness in older adults to obtain reliable regularity features and references.

Factors associated with poor appetite among residents at selected long-term care facilities in Selangor, Malaysia

@#Introduction: Poor appetite is prevalent among older adults and may negatively impact on their overall health. This is especially true for institutionalised residents. Despite this, there is a paucity of research on appetite and its associated factors among institutionalised residents, which signified the present study. Methods: A cross-sectional study was conducted among elderly residents at long-term care facilities in the state of Selangor, Malaysia to ascertain their appetite status and its associated factors. Results: A total of 97 residents with mean age of 74.2±8.4 years old were recruited. They comprised 61.9% females and 38.1% males. More than 50% had poor appetite with early satiety. There were 63.0%, 82.4%, and 94.8% who had poor oral health, poor sleep quality, and depression, respectively. Ethnicity (OR=2.73; 95% CI=1.00-7.44; p=0.049) was the only factor that predicted poor appetite among older adults in long-term care facilities, with Malay residents having poorer appetite than their Chinese and Indian counterparts. Conclusion: The prevalence of poor appetite was high among residents staying at long-term care facilities in Selangor, Malaysia, especially among Malays. This issue deserves further studies to identify the specific underlying factors contributing to poor appetite among older adults from different ethnicities. Acknowledging the high prevalence of poor appetite among older adults and its possible unfavourable outcomes, appropriate nutrition interventions are therefore needed to address this issue among institutionalised elderly.

Effects of high-intensity interval training with different intervention durations on cognitive function in older adults:a Meta-analysis / 中国组织工程研究

OBJECTIVE:With the increasing aging population,the decline of cognitive ability in older adults has received widespread attention.High-intensity interval training(HIIT)has been applied as an emerging exercise intervention to improve cognitive ability in older adults,but its efficacy is still controversial.This study aimed to investigate the effects of HIIT intervention on cognitive ability in older adults,in order to provide a theoretical basis for its application in improving cognitive ability in older adults. METHODS:Randomized controlled trials regarding the effect of HIIT on cognitive ability in older adults were retrieved from databases including CNKI,WanFang,PubMed,Embase,and Web of Science,from the database inception to November 2022.The Cochrane Collaboration's tool for assessing risk of bias in randomized controlled trials was used to evaluate the methodological quality,and RevMan 5.3 software was used for the Meta-analysis of outcome indicators in the included literature. RESULTS:A total of 8 randomized controlled trials,including 4 high-quality and 4 low-quality studies with 369 participants,were included in the Meta-analysis.Meta-analysis showed that(1)compared with moderate-intensity continuous training(MICT),HIIT could effectively improve the maximal oxygen uptake of older adults[weighted mean difference(WMD)=3.78,95%confidence interval(CI):2.79,4.77,P＜0.000 01].Subgroup analysis showed that with long-term intervention(intervention period≥6 weeks),compared with the MICT group,the HIIT group could significantly improve the executive function[standardized mean difference(SMD)=0.36,95%CI:0.20-0.52,P＜0.000 1)and its sub-function inhibition ability(SMD=0.35,95%CI:0.17-0.52,P＜0.000 1)of older adults.(2)Compared with the control group,the HIIT group could effectively improve the maximal oxygen uptake of older adults(WMD=6.75,95%CI:4.20-9.29,P＜0.000 01),memory(SMD=0.20,95%CI:0.03-0.37,P=0.02),executive function(SMD=0.87,95%CI:0.52-1.22,P＜0.000 01),and its sub-function inhibition ability(SMD=0.89,95%CI:0.46-1.33,P＜0.000 1).Subgroup analysis showed that with long-term intervention(intervention period≥6 weeks),compared with the control group,the HIIT group could effectively improve the executive function(SMD=0.75,95%CI:0.41-1.09,P＜0.000 1),its sub-function inhibition ability(SMD=0.50,95%CI:0.19-0.81,P=0.002),and switching ability(SMD=1.65,95%CI:0.86-2.44,P＜0.000 1).(3)With a single intervention,compared with the control group,the HIIT group could effectively improve the executive function(SMD=1.25,95%CI:0.39-2.11,P=0.004)and its sub-function inhibition ability(SMD=2.40,95%CI:0.87-3.92,P=0.002). CONCLUSION:HIIT can effectively improve the executive function and its sub-function inhibition ability of older adults,but has no improvement effect on memory ability.At the same time,long-term HIIT intervention is superior to MICT in improving aerobic capacity and executive function of older adults.

Relationship between life satisfaction of family caregivers and degree of disability of disabled elderly people in Xinjiang / 中国心理卫生杂志

Objective:To explore the relationship between the life satisfaction of family caregivers and the de-gree of disability of disabled elderly people in Xinjiang Uygur and Kazak nationality,and the role of family mem-bers'participation in the relationship.Methods:A total of 431 elderly people with disabilities at home and their fam-ily caregivers(247 without family members and 184 with family members)were selected from Xinjiang Uygur and Kazak ethnic groups,and the survey was conducted with the Activity of Daily Living Scale(ADL)and Life Satis-faction Index B(LSIB).Results:The LSIB scores in family caregivers were negatively correlated with the ADL scores in the disabled elderly(r=-0.19,P＜0.01),and the family members'participation in care was positively correlated with the LSIB scores of family caregivers(r=0.52,P＜0.01).Family members'participation in care could moderate the negative effect of the ADL scores in the disabled elderly on the LSIB scores in family caregivers(β=0.08,P＜0.05).Conclusion:The involvement of family members in care has a moderating effect on the life satisfaction of Uyghur and Kazak family caregivers and the degree of disability of disabled elderly people.

Development trajectories and influencing factors of self-neglect behavior in older adults / 中华行为医学与脑科学杂志

Objective:To identify the development trajectories of self-neglect behavior in older adults and explore the associated influencing factors.Methods:A fixed cohort was constructed based on the data from three surveys of Chinese longitudinal healthy longevity survey (CLHLS) from 2011 to 2018. A total of eight variables from 4 dimensions including living environment, lifestyle, social interaction, and health care were selected to evaluate self-neglect. Group-based trajectory model was used to identify the development trajectory of self-neglect behavior in the older adults, and polynomial Logistic regression model was used to explore its influencing factors by Stata 16.1.Results:Finally, 2 754 older adults aged 60 and above were included.The development trajectory of self-neglect behavior in older adults, based on the group-based trajectory model, can be classified into stable-low group ( n=268, 9.7%), descending-moderate group ( n=2 224, 80.8%), and decreasing-high group ( n=262, 9.5%). Polynomial Logistic regression showed that, compared with stable-low group, living in rural areas ( B=1.116, OR=3.053, 95% CI= 2.278-4.091) and higher activities of daily living scores( B=0.137, OR=1.147, 95% CI=1.046-1.258) were the risk factors of descending-moderate group. Education levels with 1-6 years( B=-0.398, OR=0.672, 95% CI=0.469-0.963), >6 years( B=-1.072, OR=0.342, 95% CI=0.229-0.513), being married( B=-0.476, OR=0.621, 95% CI=0.444-0.870), self-reported good health( B=-0.808, OR=0.446, 95% CI= 0.213-0.932), improved health status( B=-0.704, OR=0.495, 95% CI=0.320-0.766), self-reported average economic status( B=-1.065, OR=0.345, 95% CI=0.148-0.802), self-reported good economic status( B=-1.634, OR=0.195, 95% CI=0.082-0.467), and a higher cognition score( B=-0.142, OR=0.867, 95% CI=0.798-0.942) served as protective factors of descending-moderate group. In addition to the above factors, being in the age group of 75-89 years( B=0.481, OR=1.617, 95% CI=1.057-2.473) was a risk factor for decreasing-high group compared to stable-low group. Conclusions:Three types of self-neglect behavior trajectories among older adults were identified in this study, suggesting that physical health and economy are the influencing factors of the development trajectory of self-neglect of the elderly.

Predictive value of gait and balance on frailty in community-dwelling older adults in Shanghai, China / 中国康复理论与实践

ObjectiveTo explore the predictive value of gait and balance on the frailty in community-dwelling older adults aged 65 years and older in Shanghai. MethodsA total of 414 community-dwelling older adults aged 65 years or older were recruited from Shanghai, from December, 2022 to April, 2023. They were investigated with Fried's Frailty Phenotype Scale, Timed Up and Go Test (TUGT), one leg standing test (OLST) and self-designed questionnaire. The factors related to frailty were analyzed using multivariate Logistic regression. ResultsThe prevalence of pre-frailty and frailty were 62.8% and 10.9%, respectively. Living in rural residence, older age, low income, smoking, sedentary lifestyle and no regular exercise were the risk factors for frailty among community-dwelling older adults. Time of TUGT increased, and time of closed eyes OLST descreased respectively in the frail older adults (P < 0.05). The area under curve was 0.846 (95% CI 0.808 to 0.884, P < 0.001) as prediction for frailty using the combination of TUGT and closed eye OLST, with a sensitivity of 0.726 and a specificity of 0.817 at the optimal threshold. ConclusionGait and balance may be a valuable predictor of frailty in community-dwelling older adults in Shanghai.

Association between sTREM2, an immune biomarker of microglial activation, and frontal lobe function in community-dwelling older adults: a cross-sectional study / Journal of Rural Medicine

Objective: Identifying the peripheral biomarkers related to the prevention or modification of unhealthy mental conditions in older adults is extremely beneficial. This study aimed to evaluate the serum levels of soluble triggering receptor expressed on myeloid cells 2 (sTREM2), a soluble form of an innate immune receptor expressed on microglia, in older adults living in a rural community, and their association with cognitive function.Materials and Methods: This survey was conducted between November 2016 and September 2017 in Kurokawa-cho, Imari, Saga Prefecture, Japan, among people aged ≥65 years. Blood samples were collected from the participants for serum sTREM2 level analysis using a peptide enzyme immunoassay. The participants underwent cognitive function assessments, including the Mini-Mental State Examination, Clinical Dementia Rating, and Frontal Assessment Battery. Therefore, we examined the association between serum sTREM2 levels and cognitive function.Results: Of the 95 participants, 25 were men and 70 were women with a mean age 78.24 ± 3.85 years and 77.96 ± 5.52 years, respectively. Serum sTREM2 levels were negatively associated with Frontal Assessment Battery scores, even after adjusting for age, sex, years of education, and serum high-sensitivity C-reactive protein levels.Conclusion: Serum sTREM2 levels may be associated with frontal lobe function in adults aged ≥65 years.
