Comparação da fadiga relacionada ao câncer de pacientes em tratamento com imunoterápicos ou quimioterápicos / Comparison of cancer-related fatigue in patients undergoing treatment with immunotherapeutic or chemotherapeutic drugs

INTRODUÇÃO: A Fadiga Relaciona ao Câncer (FRC) é uma "sensação persistente e subjetiva de cansaço e esgotamento físico, emocional, e/ou cognitivo, relacionado com o câncer ou o tratamento do mesmo, que não é proporcional à atividade recente e que interfere na capacidade funcional". A FRC, que atinge até 80% dos pacientes, é relatada principalmente por pacientes em tratamento quimioterápico. OBJETIVO: Comparar a fadiga relacionada ao câncer de pessoas com tumores sólidos em tratamento com imunoterapia ou quimioterapia. METODOLOGIA: Foi um estudo observacional transversal analítico, em pacientes adultos, de ambos os sexos, com câncer sólido, que no momento da coleta estavam exclusivamente em tratamento com quimioterápicos ou imunoterápicos. Os voluntários foram separados em dois grupos: grupo Imunoterapia e grupo Quimioterapia. Os instrumentos de avaliação foram: questionário de Avaliação Funcional da Terapia de Doenças Crônicas ­ Fadiga (FACIT-F), que avalia a percepção de fadiga da pessoa em tratamento do câncer. A dinamometria com o dinamômetro Jamar® para avaliar força de preensão manual e teste de velocidade da marcha de 4 metros (VM4M) para avaliar a velocidade da marcha. RESULTADOS: Em relação a velocidade da marcha, o grupo imuno apresentou velocidade média de 1,43 m/s e o grupo quimio apresentou velocidade média de 1,41m/s. Esses resultados apresentam que os pacientes avaliados não apresentaram lentidão de marcha e não tem diferença estatística entre os grupos (p=0.43). Em relação à força de preensão manual, observamos que não tem diferença estatística entre os grupos estudados (p=0,13 mão direita e p=0,10 mão esquerda), porém observamos que o grupo Imunoterapia contém valores maiores de média e mediana para a força de preensão palmar em ambas as mãos, permitindo afirmar que nos pacientes estudados em tratamentos com imunoterápicos apresentaram maior força de preensão manual. Em relação ao inventário de fadiga observa-se que, na amostra estudada, a média do escore final comprova que o grupo Imunoterapia tem menor ocorrência de fadiga (p=0.01). CONCLUSÃO: Não houve diferença estatística entre os grupos na velocidade da marcha e na força de preensão manual. No inventário de fadiga o grupo imunoterapia apresentou menor ocorrência de fadiga com diferença significativa.

INTRODUTION: Cancer Relational Fatigue (CRF) is a "persistent and subjective feeling of tiredness and physical, emotional, and/or cognitive exhaustion, related to cancer or its treatment, which is not proportional to recent activity and which interferes in functional capacity". CRF that meets up to 80% of patients is mainly reported by chemotherapy treatment. Patients being treated with immunotherapics report less fatigue. OBJECTIVE: Compare cancer-related fatigue in people with solid tumors undergoing exclusive immmunotherapy or chemotherapy treatments. This was an observational, cross-sectional and analytical study conducted with adult patients of both genders. The volunteers were distributed in two groups, namely, Immunotherapy and Chemotherapy. The assessment instruments were as follows: Functional Assessment Questionnaire of Chronic Illness Therapy ­ Fatigue (FACIT-F), dynamometry with a Jamar® dynamometer to assess hand grip strength and the 4-meter gait speed (4MGS) test. RESULTS: In relation to gait speed, the Immunotherapy group presented a mean speed of 1.43 m/s while the mean speed in the Chemotherapy group was 1.41 m/s. These results indicate that the patients evaluated did not present low gait speed and do not statistically differ between the groups (p=0.43). In relation to hand grip strength, we did not observe any significant difference between the groups under study (p=0.13 right hand and p=0.10 left hand). However, we noticed that the Immunotherapy group has higher mean and median values for hand grip strength in both hands, allowing us to assert that the patients studied in immunotherapy treatments presented greater hand grip strength. In relation to the fatigue inventory, in the sample studied it is observed that the final score mean proves that the Immunotherapy group presents lower occurrence of fatigue (p=0.01). CONCLUSION: There was no statistical difference between the groups in gait speed and handgrip strength. In the fatigue inventory, the immunotherapy group had a lower occurrence of fatigue with a significant difference.

Strength and strength-related anthropometric parameters of the international level canoe slalom male paddlers / Fuerza y parámetros antropométricos relacionados con la fuerza de los hombres remeros de canotaje slalom de nivel internacional

SUMMARY: The aim of the study was to determine the differences in hand-grip strength and strength-related anthropometric parameters between the highest-performance international paddlers (HILP) and other international paddlers (ILP) in canoe slalom. In male competitors (n=48; 23 canoeists and 25 kayakers) who took part in the 2018 European championship event in canoe slalom in Prague, Czech Republic representing 15 European countries were measured hand-grip strength and strength-related anthropometric parameters two days prior the event. Differences between the group of HILP (medallists from Olympic Games, world championship and European championship in the previous three years and European championship finalists at the same time) and ILP were found. HILP have significantly higher forearm, arm and chest girths than ILP. Moderate or high practical differences and margin statistic differences were found also for hand-grip strength, body weight, body mass index and age. The consistently high-performing paddlers are heavier, have more muscular upper body and are stronger than the other group, while keeping their lower body lean. Therefore, regular upper-body strength training to all canoe slalom paddlers is important but caution is required because body weight over 80 kg may be a limiting factor.

RESUMEN: El objetivo del estudio fue determinar las diferencias en la fuerza de prensión manual y los parámetros antropométricos relacionados con la fuerza entre los remeros internacionales de alto rendimiento (RIAR) y otros remeros internacionales de canotaje en slalom. En hombres competidores (n=48; 23 piragüistas y 25 kayakistas) que participaron en el campeonato europeo de slalom en canoa de 2018, en Praga, República Checa, que representa a 15 países europeos, se midió la fuerza de agarre manual y los parámetros antropométricos relacionados con la fuerza dos días antes del evento. Se encontraron diferencias entre el grupo de RIAR (medallistas de Juegos Olímpicos, campeonatos del mundo y campeonatos de Europa en los tres años anteriores y finalistas del campeonato de Europa al mismo tiempo) y remeros internacionales. Los RIAR presentaban circunferencias de antebrazo, brazo y pecho significativamente más altas que los remeros internacionales. Además, se encontraron diferencias prácticas moderadas o altas y diferencias estadísticas en el límite para la fuerza de prensión manual, el peso corporal, el índice de masa corporal y la edad. Los remeros de alto rendimiento son más pesados, tienen la parte superior del cuerpo más musculosa y son más fuertes que el otro grupo, mientras mantienen la parte inferior del cuerpo esbelta. Por lo tanto, es importante el entrenamiento regular de fuerza de la parte superior del cuerpo para todos los remeros de piragüismo, sin embargo se requiere precaución debido a que el peso corporal superior a 80 kg puede ser un factor limitante.

Conclusión: la relación entre la fuerza de agarre reducida y la disminución de la funcionalidad determina la condición de fragilidad física en los ancianos. Esto refuerza la importancia de que los profesionales de Enfermería inviertan en intervenciones que permitan mantener la fuerza y la funcionalidad muscular y revertir la fragilidad física en este segmento de la población.

ABSTRACT Objective: to analyze scientific publications on the relationship between handgrip strength, functionality, and physical frailty in the elderly. Method: integrative review carried out in PubMed, CINAHL, Web of Science and VHL Portal databases, in the sample period from January 2010 to November 2021. The Preferred Reporting Items for Systematic Reviews and Meta-analyses flowchart was used to present the selection of studies, and the level of evidence was assessed from the Oxford Center for Evidence-Based Medicine and references managed in EndNote Web. Results: the initial search resulted in 211 studies after applying the eligibility criteria, with 7 studies constituting the integrative review. Handgrip strength proved to be an important indicator of muscle strength and crucial for the functionality of elderly people. When associated with certain clinical occurrences, handgrip strength contributes to the reduction of functionality and dependence in carrying out activities of daily living in the elderly, with greater impairment among those aged 75 years or older, more significantly among women. Conclusion: the relationship between reduced grip strength and decreased functionality determines the condition of physical frailty in elderly people. This reinforces the importance of investment by Nursing professionals in interventions that enable the maintenance of muscle strength and functionality and the reversal of physical frailty in this population segment.

Is sleep time associated with handgrip strength in adolescents from the 1997/1998 São Luís Birth Cohort? / O tempo de sono está associado à força de preensão manual em adolescentes da Coorte de São Luís de 1997/1998?

Abstract This article aims to analyze the association between sleep time and handgrip strength in adolescents belonging to the 1997/1998 São Luís Birth Cohort. This was a cross-sectional study nested in a birth cohort study. One thousand two hundred sixty-nine individuals (18 and 19 years) wore an Actigraph® GTX3+ accelerometer on their wrist 24 hr/day for 7 consecutive days. Handgrip strength was measured using a digital hand dynamometer. We used directed acyclic graphs (DAG) to identify confounding variables. This sample of adolescents was mostly composed of men, with brown skin color, economic class C, which did not work, did not consume alcohol, did not smoke, and never used drugs. The mean value of handgrip strength was 28.2 (±9.3) kgf, and the mean of sleep time was 6 (±1.0) hours per day. The crude analysis showed an association between sleep time and muscle strength. An increase of one hour of sleep reduced the handgrip strength by 1.95 kgf (95%CI:-2.51;-1.39). However, after adjustment for confounders, the association was not maintained (β:-0.07; 95%CI:-0.48;0.36). Sleep time is not associated with handgrip strength in adolescents in São Luís.

Resumo O objetivo deste artigo é analisar a associação entre tempo de sono e força de preensão manual em adolescentes da Coorte de Nascimentos de São Luís 1997/1998. Estudo transversal aninhado a um estudo de coorte de nascimentos. Mil duzentos e sessenta e nove indivíduos (18 e 19 anos) usaram um acelerômetro Actigraph® GTX3 + em seu pulso 24 horas/dia por sete dias consecutivos. A força de preensão manual foi medida por meio de um dinamômetro digital de mão. Usou-se gráficos acíclicos direcionados (DAG) para identificar variáveis ​​de confusão. A amostra de adolescentes foi composta em sua maioria por homens, de cor da pele parda, classe econômica C, que não trabalhava, não consumiam álcool, não fumavam e nunca usaram drogas. O valor médio da força de preensão manual foi de 28,2 (±9,3) kgf, e a média do tempo de sono foi de seis (±1,0) horas por dia. A análise bruta mostrou associação entre tempo de sono e força muscular. O aumento de uma hora de sono reduziu a força de preensão manual em 1,95 kgf (IC95%:-2,51;-1,39). No entanto, após o ajuste para fatores de confusão, a associação não foi mantida (β:-0,07; IC95%:-0,48;0,36). O tempo de sono não foi associado à força de preensão manual em adolescentes de São Luís.

Correlação entre funcionalidade e força de preensão manual e a condição de fragilidade física em idosos da atenção primária à saúde / Correlation between functionality and handgrip strength and the condition of physical frailty in elderly people in primary health care

Resumo: Trata-se de estudo quantitativo transversal cujo objetivo foi analisar a correlação entre funcionalidade e força de preensão manual e a condição de fragilidade física em idosos da atenção primária à saúde. Participaram 389 idosos (=60 anos) de ambos os sexos, cadastrados em uma Unidade Básica de Saúde de Curitiba, Paraná. A coleta de dados ocorreu de janeiro a novembro de 2019, foi precedida pela aplicação do miniexame do estado mental, seguida dos questionários sociodemográfico e clínico, escala da medida de independência funcional (MIF) e avaliação da fragilidade física. Os dados foram organizados no programa Microsoft Excel® 2007 e analisados no software R CORE TEAM, mediante estatística descritiva, análises bivariadas (p<0,05), testes de Kruskal-Wallis, Dunn, qui-quadrado e Spearman. Dos 389 idosos, 34 (8,7%) eram frágeis, 186 (47,8%) pré-frágeis, 169 (43,5%) não frágeis, 255 (65,6%) do sexo feminino e 186 (47,8%) na faixa etária entre 60 e 69 anos. A FPM reduzida foi identificada em 82 (21%) idosos e distribuída entre 27 (79,5%) frágeis e 55 (29,5%) pré-frágeis. Houve correlação significativa entre funcionalidade e força de preensão manual segundo à condição de fragilidade física (Pˆ= 0,330; p=<0,001). A média da FPM foi maior no grupo de idosos não frágeis (28,9 Kgf), comparada aos pré-frágeis (24,6 Kgf) e frágeis (17,1 Kgf). A pontuação média da funcionalidade (MIF) foi maior no grupo de idosos não frágeis (122,1 pontos) em relação aos pré-frágeis (120,6pontos) e frágeis (114,2 pontos). Quanto à tarefa da MIF "controle de urina", observou-se elevada frequência idosos frágeis completamente dependentes (n=9; 26,4%) e pré-frágeis moderadamente dependentes (n=52; 27,9%). Para a tarefa "interação social" observou-se expressiva frequência de idosos frágeis moderadamente dependentes(n=12; 35,3%). Para a tarefa "resolução de problemas" evidenciou-se a mesma frequência (n=7; 20,6%) de idosos frágeis completamente dependentes e moderadamente dependentes. Na avaliação da tarefa "memória" destacaram-se os pré-frágeis moderadamente dependentes (n=26; 14%). A correlação entre funcionalidade (MIF) e FPM se mostrou fraca, positiva e significativa entre os idosos da amostra investigada (Pˆ= 0,330; p=<0,001), entre os não frágeis (Pˆ= 0,252;p=<0,001) e entre os pré-frágeis (Pˆ= 0,236; p=0,001). O desempenho nas tarefas "controle de urina" e "subir e descer escadas" correlacionou-se significativamente à FPM (p=<0,005) entre os idosos pré-frágeis. Destacam-se, com maior coeficiente de correlação com a FPM, as tarefas "controle de urina" para os idosos não frágeis (Pˆ=0,309) e "subir e descer escadas" para os pré-frágeis (Pˆ=0,222). Já a tarefa "resolução de problemas" correlacionou-se à FPM entre os idosos pré-frágeis (p=<0,004) e frágeis (p=<0,017), sendo entre esses o maior coeficiente de correlação (Pˆ= 0,408). Verifica-se ainda a correlação entre a tarefa "expressão verbal e não verbal" e a FPM para o grupo de idosos frágeis (p=<0,025; Pˆ= 0,383). Conclui-se que houve correlação positiva entre funcionalidade e FPM entre os idosos não frágeis e pré-frágeis, indicando que quanto maior a FPM, melhor é o desempenho funcional. Destacam-se resultados expressivos para a prática clínica de enfermagem gerontológica, que podem subsidiar estratégias preventivas voltadas à manutenção da FPM e da funcionalidade, principalmente entre os idosos não frágeis e pré-frágeis.

Abstract: This is a cross-sectional quantitative study whose objective was to analyze the correlation between functionality and handgrip strength and the condition of physical frailty in elderly people in primary health care. Participants were 389 elderly people (=60 years) of both sexes, registered at a Basic Health Unit in Curitiba, Paraná. Data collection took place from January to November 2019, was preceded by the application of the mini-mental state exam, followed by sociodemographic and clinical questionnaires, functional independence measure scale (FIM), and assessment of physical frailty. Data were organized in Microsoft Excel® 2007 program and analyzed in R CORE TEAM software, using descriptive statistics, bivariate analyzes (p<0.05), Kruskal-Wallis, Dunn, chi-square, and Spearman tests. Of the 389 elderly, 34 (8.7%) were frail, 186 (47.8%) were pre-frail, 169 (43.5%) were non-frail, 255 (65.6%) were female and 186 (47.8%) in the age group between 60 and 69 years. Reduced HGS was identified in 82 (21%) elderly and distributed among 27 (79.5%) frail and 55 (29.5%) pre-frail. There was a significant correlation between functionality and handgrip strength according to the condition of physical frailty (Pˆ=0.330; p=<0.001). The average HGS was higher in the group of non-frail elderly (28.9 Kgf), compared to pre-frail (24.6 Kgf) and frail (17.1 Kgf). The mean functionality score (MIF) was higher in the group of non-frail elderly (122.1 points) compared to pre-frail (120.6 points) and frail (114.2 points). As for the FIM task "urine control", a high frequency of completely dependent frail elderly (n=9; 26.4%) and moderately dependent pre-frail (n=52; 27.9%) was observed. For the "social interaction" task, there was a significant frequency of moderately dependent frail elderly was observed (n=12; 35.3%). For the "problem solving" task, the same frequency (n=7; 20.6%) of completely dependent and moderately dependent frail elderly individuals was observed. In the evaluation of the "memory" task, the moderately dependent pre-frail stood out (n=26; 14%). The correlation between functionality (MIF) and HGS was weak, positive, and significant among the elderly in the investigated sample (Pˆ= 0.330; p=<0.001), among the nonfrail (Pˆ=0.252; p=<0.001) and among the elderly. pre-fragile (Pˆ= 0.236; p=0.001). The performance in the tasks "urine control" and "going up and down stairs" was significantly correlated with HGS (p=<0.005) among the pre-frail elderly. The tasks "urine control" for the non-frail elderly (Pˆ=0.309) and "going up and down stairs" for the pre-frail stand out, with the highest correlation coefficient with HGS (Pˆ=0.222). The "problem solving" task was correlated with HGS among pre-frail (p=<0.004) and frail (p=<0.017) elderly, with the highest correlation coefficient (Pˆ=0.408) among these. There is also a correlation between the task "verbal and non-verbal expression" and HGS for the frail elderly group (p=<0.025; Pˆ=0.383). It was concluded that there was a positive correlation between functionality and HGS among the non-frail and pre-frail elderly, indicating that the higher the HGS, the better the functional performance. Significant results for the clinical practice of gerontological nursing stand out, which can support preventive strategies aimed at maintaining HGS and functionality, especially among non-frail and pre-frail elderly people.

Hemodynamics and functional outcomes after resistance training in hypertensive and normotensive elderly: An experimental study

Abstract Aim: To evaluate the chronic effects of resistance training on resting blood pressure, handgrip strength, gait speed, and Timed Up and Go test (TUG) in normotensive and hypertensive elderly individuals. Methods: Experimental study based on TREND. Hypertensive patients were diagnosed by an independent doctor. Before and after 12 weeks of progressive resistance training, we evaluated blood pressure, heart rate, body composition, Timed Up and Go test, gait speed, and handgrip strength. Results: Sample consisted of 41 participants divided into two groups (normotensive n = 28; hypertensive n = 13). We observed significant values in the reduction of blood pressure levels only in the group of hypertensive participants. In functionality outcomes, we observed significant values in all tests and both groups. Outcomes contemplate effect sizes ranging from small to moderate. Conclusion: Progressive resistance training lowers resting blood pressure levels, increases handgrip strength, and improves physical functional performance. Although the normotensive group did not show a reduction in blood pressure levels, an improvement was observed in the functional physical tests.

Prevalence of and risk factors for dynapenic abdominal obesity in community-dwelling older adults: a cross-sectional study / Prevalência e fatores de risco para obesidade abdominal dinapênica em idosos residentes na comunidade: um estudo transversal

Abstract This article aims to identify the prevalence of and factors associated with dynapenic abdominal obesity (DAO) in older adults in a city in the northern region of Brazil. A cross-sectional study was conducted with 382 community-dwelling older adults in Macapa, Amapa, Brazil. Socioeconomic, clinical, and health information were collected using a structured form. DAO was defined as a combination of dynapenia (handgrip strength of < 26 kgf for men and < 16 kgf for women) and abdominal obesity (abdominal circumference > 102 cm for men and > 88 cm for women). Descriptive and inferential analyses were performed using chi-squared tests, Student's t-tests, and a Poisson regression. The prevalence of DAO was 10.73%. In the preliminary bivariate analysis, the variables of age range, marital status, number of diseases, functional disability for basic and instrumental activities of daily living, gait speed, and level of physical activity met the established criterion. The final model indicated that only gait speed was a predictor of DAO in older adults. DAO affects nearly 11% of community-dwelling older adults from northern Brazil; gait speed was a predictor of DAO and could be a useful tool for managing and monitoring this population's health.

Resumo O objetivo deste artigo é identificar a prevalência e os fatores associados à obesidade abdominal dinapênica (OAD) em idosos de uma cidade da região Norte do Brasil. Estudo transversal realizado com 382 idosos comunitários residentes em Macapá, Amapá, Brasil. As informações socioeconômicas, clínicas e de saúde foram coletadas por meio de um formulário estruturado. A OAD foi definida pela combinação de dinapenia (força de preensão manual < 26 kgf para homens e < 16 kgf para mulheres) e obesidade abdominal (circunferência abdominal > 102 cm para homens e > 88 cm para mulheres). As análises descritivas e inferenciais foram realizadas utilizando os testes qui-quadrado, t de Student e regressão de Poisson. A prevalência de OAD foi de 10,73%. Na análise bivariada preliminar, as variáveis faixa etária, estado conjugal, número de doenças, incapacidade funcional para atividades básicas e instrumentais de vida diária, velocidade da marcha e nível de atividade física atenderam ao critério estabelecido. O modelo final indicou que apenas a velocidade da marcha foi um preditor para a OAD em idosos. A OAD afeta quase 11% dos idosos residentes nessa comunidade do Norte do Brasil; e a velocidade de marcha é um preditor que pode ser uma ferramenta útil para gerenciar e monitorar a saúde desta população.

The correlation of sleep duration and insomnia with low muscle mass, strength and quality in Chinese adults / 中华流行病学杂志

Objective: To explore the relationship of sleep duration and insomnia with muscle mass, strength, and quality in Chinese adults. Methods: Based on the second resurvey of China Kadoorie Biobank (CKB) in 2013-2014, logistic regression models were used to analyze the correlation of sleep duration, insomnia, and its duration with low muscle mass, handgrip strength, and muscle quality. Results: The average sleep duration of the study population was (7.4±1.5) hours. Morbidities of short sleep duration (<6 hours), long sleep duration (≥9 hours), and insomnia were 9.3%,17.4%,and 29.9%,respectively. Compared with those who slept for 7- hours, those who slept for ≥9 hours were more likely to have low muscle mass, low handgrip strength,and low arm muscle quality (AMQ), and the OR (95%CI) of low appendicular skeletal muscle mass index (ASMI), low total skeletal muscle mass index (TSMI), low grip strength and low AMQ were 1.32 (1.18-1.48),1.26 (1.13-1.41), 1.33 (1.18-1.49) and 1.16 (1.03-1.30), respectively. Compared with participants without insomnia, insomnia patients were more likely to have low muscle mass,and the longer the duration of insomnia,the higher the risk (P for trend <0.001). Participants who reported <6 hours sleep duration and insomnia had a higher proportion of low ASMI and low TSMI,compared with those who slept for 7- hours and without insomnia, the OR (95%CI) were 1.26 (1.08-1.47) and 1.25 (1.07-1.46), respectively. Conclusions: Participants who reported ≥9 hours sleep duration were more likely to have low muscle mass,low handgrip strength,and low AMQ. Participants with insomnia had lower muscle mass, and the longer the duration of insomnia, the higher the proportion of low ASMI and low TSMI.

Insuficiência familiar e a condição e os marcadores de fragilidade física de idosos em assistência ambulatorial / Insuficiencia familiar y la condición y los marcadores de fragilidad física de ancianos en asistencia ambulatorial / Family insuficiency and the condition and the physical frailty's components of elderly in ambulatorial care

RESUMO Objetivo analisar a relação entre insuficiência familiar e a condição e os marcadores de fragilidade física de idosos acompanhados em ambulatório de Geriatria e Gerontologia. Método estudo quantitativo e transversal realizado com 384 idosos (≥ 60 anos) selecionados por critérios pré-estabelecidos de inclusão e exclusão. Avaliaram-se a fragilidade física segundo o fenótipo da fragilidade e a insuficiência familiar pelo APGAR de Família. Analisaram-se os dados mediante a estatística descritiva e a análise univariada mediante o teste de qui-quadrado com nível de significância estatístico de p≤0,05. Resultados não houve associação entre insuficiência familiar e fragilidade física (p=0,344), entretanto, observou-se percentual de idosos frágeis com elevada Disfunção Familiar (22,2%) e moderada Disfunção Familiar (19,4%), maior que o observado entre os idosos com boa funcionalidade familiar (12,2%). Entre os idosos frágeis para o marcador "fadiga/exaustão", houve proporcionalidade direta ao grau de Disfunção Familiar e relação estatisticamente significativa ao escore total do APGAR de Família (p=0,001). Conclusão e implicações para a prática a insuficiência familiar no idoso está relacionada a outros fatores intrafamiliares e não exclusivamente à fragilidade física, no entanto, pode-se afirmar que o grau de fragilidade física entre os idosos é diretamente proporcional ao nível de Disfunção Familiar.

ABSTRACT Objective to analyze the relationship between family insufficiency and the condition and the markers of physical frailty of elderly people followed up in a Geriatrics and Gerontology outpatient clinic. Method a quantitative and cross-sectional study conducted with 384 elderly (≥ 60 years) selected by pre-established inclusion and exclusion criteria. Physical frailty was assessed according to the frailty phenotype and family insufficiency by the Family APGAR. Data was analyzed using descriptive statistics and univariate analysis using the chi-square test with a statistical significance level of p≤0.05. Results there was no association between family insufficiency and physical frailty (p=0.344), however, it was observed a percentage of frail elderlies with high Family Dysfunction (22.2%) and moderate Family Dysfunction (19.4%), higher than that observed among the elderly with good family functioning (12.2%). Among the frail elderly for the marker "fatigue/exhaustion", there was a direct proportionality to the degree of Family Dysfunction and a statistically significant relation to the total score of the Family APGAR (p=0.001). Conclusion and implications for the practice family frailty in the elderly is related to other intra-family factors and not exclusively to physical frailty, however, it can be stated that the degree of physical frailty among the elderly is directly proportional to the level of Family Dysfunction.

Gender and education inequalities in dynapenia-free life expectancy: ELSI-Brazil

ABSTRACT OBJECTIVE To estimate the dynapenia-free life expectancy among community-dwelling older Brazilian adults and evaluate gender-related and educational differences. METHODS This is a cross-sectional study. The data were obtained from the Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brazil - Brazilian Longitudinal Study of Aging), conducted from 2015 to 2016 in Brazil. Dynapenia is defined as low muscle strength (< 27kg for men and < 16kg for women), measured with a handgrip dynamometer. The dynapenia-free life expectancy was estimated using the Sullivan method based on the standard period life table and dynapenia prevalence, stratified by age groups, gender, and schooling. RESULTS A total of 8,827 participants, aged 50 and over (53.3% women), were investigated. The prevalence of dynapenia was 17.7% among men and 18.5% among women. The women live longer and with more years free of dynapenia than men. Those in the higher education category (four or more years) presented an advantage in the dynapenia-free life expectancy estimates. CONCLUSIONS The results of this study suggest the substantial impact of dynapenia on longer dynapenia-free life expectancy among older people. Understanding dynapenia prevalence and dynapenia-free life expectancy could assist in predicting care needs, as well as targeting efforts to delay the onset of complications related to it at older ages. Without the implementation of policy regarding dynapenia prevention, inequalities in health due to gender and socioeconomic status may continue to increase.

Grip strength is a strong predictor of survival in nonagenarians and centenarians / Força de preensão palmar e sobrevivência em nonagenários e centenários

Objectives: To understand the importance of hand grip strength (HGS) as a survival predictor in nonagenarians and centenarians. Methods: Longitudinal, observational and analytical study, using HGS measurements obtained during a first evaluation performed in 2016. Participants were nonagenarians and centenarians, randomly selected in various neighborhoods of Porto Alegre (RS) and evaluated in their homes. The time elapsed between the first evaluation and the date of death or last contact (for survivors) was used to calculate the hazard ratio (HR) using survival analysis on simple and adjusted Cox regression models. Results: The sample comprised 212 participants (155 women), of whom 83 (39%) died during follow-up (until August 30, 2019). Using the lowest quartile (25%) for HGS, participants with < 10 kgf for women and 17 kgf for men were considered to have poor HGS performance. In the simple regression model, participants with lower HGS presented a HR of 2.75 (1.76­4.30, p < 0.001) for death. Also in the simple model, participants aged between 90 and 94 years old presented an HR of 0.37 (0.16­0.85, p = 0.019) compared to those aged 100 or older. In the adjusted model, age lost its significance in the presence of HGS. The following were significant predictors in both simple and adjusted models: cognitive performance, calf circumference, ability to participate in social activities, shop, and prepare meals alone, performance in the Timed Up and Go test, and ease to perform activities requiring upper limb strength. Conclusions: HGS was an important independent and modifiable predictor of survival among nonagenarians and centenarians.

Objetivos: Compreender a importância da força de preensão palmar (FPP) como preditor em nonagenários e centenários. Metodologia: Estudo, longitudinal, observacional e analítico, utilizando os resultados da FPP medidos na primeira avaliação realizada em 2016. Os participantes eram nonagenários e centenários, selecionados aleatoriamente em vários bairros de Porto Alegre (RS) e avaliados em suas residências. Os participantes com 10 kgf para mulheres e 17 kgf para homens foram considerados com menor desempenho da FPP. O tempo entre a primeira avaliação e a data do óbito ou último contato (entre sobreviventes) foi calculado para avaliar a Razão de Dano (RD) usando análise de sobrevida por modelos simples e ajustados da Regressão de Cox. Resultados: A amostra foi composta por 212 participantes, 155 mulheres, 83 (39%) faleceram durante acompanhamento (até 30 de agosto de 2019). Na regressão simples, os participantes com menor desempenho na FPP apresentaram RD de 2,75 (1,76 ­ 4,30, p < 0,001). No modelo simples, participantes com idade entre 90 e 94 anos, apresentaram RD de 0,37 (0,16 ­ 0,85, p = 0,019) em relação aos centenários. No modelo ajustado, a idade perdeu sua significância na presença da FPP. Foram preditores significativos nos modelos simples e ajustados: desempenho cognitivo, circunferência da panturrilha, ser capaz de participar de atividades sociais e fazer compras e preparar refeições sozinho, desempenho no teste Timed Up and Go, e a facilidade para realizar atividades que exijam membros superiores. Conclusões: Concluímos que a FPP foi um importante preditor independente de sobrevida entre nonagenários e centenários, o que poderia ser melhorado por uma intervenção clínica.

Composición corporal, parámetros bioeléctricos y fuerza de prensión manual en escaladores chilenos federados y recreativos / Body composition, bioelectrical parameters, and handgrip strength in federated and recreational Chilean climbers

RESUMEN: El objetivo del siguiente estudio fue determinar y comparar los valores de composición corporal, parámetros bioeléctricos y fuerza de prensión manual de escaladores chilenos federados y recreativos. Participaron voluntariamente 13 escaladores chilenos, de los cuales 4 eran federados (25,75 ± 2,87 años) y 9 recreativos (22,33 ± 1,41 años). La composición corporal se evaluó por medio de un impedanciómetro bioeléctrico octopolar multifrecuencia, mientras que la fuerza de prensión manual se determinó con un dinamómetro manual. Si bien no hubo diferencias en las variables de composición corporal entre ambos grupos, el ángulo de fase del tronco fue superior en los federados en comparación a los recreativos (p = 0,011 [95 % IC = 1,10; 5,20]). Respecto a la fuerza de prensión manual, la fuerza relativa fue superior para los federados (p = 0,025 [95 % IC = 0,10; 0,22]), mientras que la diferencia de la fuerza entre la mano dominante y no dominante fue mayor para los recreativos (p = 0,012 [95 % IC = 1,60; 10,05]). Este es uno de los primeros estudios que explora las diferencias entre escaladores chilenos federados y recreativos. Los resultados sugieren una diferenciación a nivel de ángulo de fase y fuerza de prensión manual, lo cual debería corroborarse con futuros estudios.

SUMMARY: This study aimed to determine and compare the body composition, bioelectric parameters, and handgrip strength in federated and recreational Chilean climbers. Thirteen Chilean climbers voluntarily participated, being 4 federated (25.75 ± 2.87 years) and 9 recreational (22.33 ± 1.41 years). Body composition was measured using a multifrequency octopolar bioelectrical impedance meter, while handgrip strength was determined with a dynamometer. Although there were no statistical differences in the body composition variables between groups, the trunk phase angle was statistically higher in the federated compared to the recreational climbers (p = 0,011 [95 % CI = 1,10; 5,20]). Regarding handgrip strength, the relative strength was higher for federated (p = 0,025 [95 % CI = 0,10; 0,22]), while the difference in strength between dominant and non-dominant hand was higher for recreational climbers (p = 0,012 [95 % CI = 1,60; 10,05]). This study is one of the first that explore the differences between federated and recreational Chilean climbers. These results suggest a differentiation at the level of phase angle and handgrip strength, which should be corroborated in future studies.

Effects of isometric handgrip training on blood pressure among hypertensive patients seen within public primary healthcare: a randomized controlled trial

ABSTRACT BACKGROUND: Meta-analyses have demonstrated that isometric handgrip training (IHT) decreases blood pressure in hypertensive individuals. Nonetheless, most studies were conducted in laboratory settings and its effects in real-world settings remain unclear. OBJECTIVE: To analyze the effects of IHT on office and ambulatory blood pressure in hypertensive patients attended within primary healthcare. DESIGN AND SETTING: Randomized controlled trial conducted in primary healthcare units within the Family Health Program, Petrolina, Pernambuco, Brazil. METHODS: 63 hypertensive patients (30-79 years old; 70% female) were randomly allocated into IHT or control groups. IHT was performed three times per week (4 x 2 minutes at 30% of maximal voluntary contraction, one-minute rest between bouts, alternating the hands). Before and after the 12-week training period, office and ambulatory blood pressure and heart rate variability were obtained. The significance level was set at P < 0.05 (two-tailed testing) for all analyses. RESULTS: IHT significantly decreased office systolic blood pressure (IHT: 129 ± 4 versus 121 ± 3 mmHg, P < 0.05; control: 126 ± 4 versus 126 ± 3 mmHg, P > 0.05), whereas there was no effect on diastolic blood pressure (IHT: 83 ± 3 versus 79 ± 2 mmHg, P > 0.05; control: 81 ± 3 versus 77 ± 3 mmHg, P > 0.05). Heart rate variability and ambulatory blood pressure were not altered by the interventions (P > 0.05 for all). CONCLUSION: IHT reduced office systolic blood pressure in hypertensive patients attended within primary care. However, there were effects regarding diastolic blood pressure, ambulatory blood pressure or heart rate variability. CLINICALTRIALS.GOV IDENTIFIER: NCT03216317.

Revisión sistemática sobre metodologías en estudios de antropometría y fuerza de mano en trabajadores / Systematic review of methodologies used in studies of anthropometry and hand force in workers

Los estudios antropométricos son el método más común de recopilar datos morfo métricos humanos utilizados para fines ergonómicos en el diseño de maquinaria, herramientas y equipos para el trabajo. Objetivo: explorar los estudios existentes a nivel mundial sobre el diseño metodológico de estudios de antropométrica de mano y fuerza de mano de las poblaciones laborales, para el periodo 2009-2019. Metodología: Se realizó una revisión sistemática de literatura nacional e internacional, haciendo uso de la estrategia PICO, se buscó material científico en bases de datos, metabuscadores y literatura gris. La revisión se realizó en 03 fases. Resultados: Se revisaron 629 investigaciones, de ellas 19 cumplieron con los criterios de inclusión, 74% describieron variables antropométricas de mano, 21% variables antropométricas de mano junto con fuerza de mano y 5% exploró la variable fisiológica fuerza de mano. Se observó que 2012 y 2016 fueron los años con el mayor número de publicaciones e India, Colombia y México los países con el mayor número de publicaciones. De los 19 estudios se extrajeron y compararon las variables población y muestra (tamaño y distribución por sexo) edad, métodos estadísticos aplicados, variables antropométricas usadas, instrumentos, equipos y técnicas de medición utilizados. Conclusiones: Evidentemente, existe escasez de datos antropométricos de mano y fuerza de mano de población laboral venezolana y es necesario realizar estudios que amplíen la data de variables antropométricas requerida para diseñar puestos de trabajo que ayuden a mejorar la salud y productividad laboral(AU)

Anthropometric studies are the most common method of collecting human morphometric data, used for ergonomic purposes in the design of machinery, tools, and equipment for work. The objective: explore existing studies worldwide on the methodological design of anthropometric studies of hand and hand strength of working populations, for the period 2009-2019. Methods: We conducted a systematic review of the national and international scientific literature, using the PICO strategy, searching databases, metasearch engines and the gray literature. The review was carried out in three phases. Results: 629 articles were identified, of which 19 met the inclusion criteria, 74% described hand anthropometric variables, 21% hand anthropometric variables together with hand strength and 5% explored the physiological variable hand strength. The years 2012 and 2016 had the highest number of publications and India, Colombia and Mexico were the countries with the greatest number of publications. From the 19 studies, we extracted and compared the population and sample variables (size and distribution by sex) age, statistical methods applied, anthropometric variables used, instruments, equipment and measurement techniques used. Conclusions: Obviously, there is a scarcity of hand anthropometric data and the Venezuelan labor force, making it necessary to conduct studies that expand the amount of data on anthropometric variables required to design jobs that help improve health and labor productivity(AU)

Osteosarcopenia and trabecular bone score in patients with type 2 diabetes mellitus

ABSTRACT Objective: To evaluate the prevalence of osteosarcopenia and the association of osteosarcopenia with trabecular bone score (TBS) in a group of patients with type 2 diabetes mellitus(T2DMG) compared with a paired control group (CG). Materials and methods: Cross-sectional study with men and women ≥ 50 years recruited by convenience. Patients in both groups answered questionnaires and underwent evaluation of bone mineral density (BMD), handgrip strength (HGS), and TBS. The T2DMG also underwent a gait speed (GS) test. Sarcopenia was defined as low lean mass plus low HGS or GS according to the Foundation for the National Institute of Health Sarcopenia Project, and osteosarcopenia was deemed present when sarcopenia was associated with osteopenia, osteoporosis, or low-energy trauma fractures. Results: The T2DMG (n = 177) and CG (n = 146) had, respectively, mean ages of 65.1 ± 8.2 years and 68.8 ± 11.0 years and 114 (64.4%) and 80 (54.7%) women. T2DMG versus the CG had higher rates of osteosarcopenia (11.9% versus 2.14%, respectively, p = 0.010), sarcopenia (12.9% versus 5.4%, respectively, p < 0.030), and fractures (29.9% versus 18.5%, respectively, p = 0.019), and lower HGS values (24.4 ± 10.3 kg versus 30.9 ± 9.15 kg, respectively, p < 0.001), but comparable BMD values. Mean TBS values were 1.272 ± 0.11 and 1.320 ± 0.12, respectively (p = 0.001). On multivariate analysis, age, greater waist circumference, fractures, and osteoporosis increased the risk of degraded TBS. Osteosarcopenia was associated with diabetes complications (p = 0.03), calcium and vitamin D supplementation (p = 0.01), and all components of osteosarcopenia diagnosis (p < 0.05). Conclusion: Compared with the CG, the T2DMG had a higher prevalence of osteosarcopenia, sarcopenia, and fractures and lower bone quality assessed by TBS.

Excess adiposity and low physical fitness hamper Supine-to-Stand test performance among sedentary adolescents

Abstract Objective: The aim of this study was to analyze the relationship between body adiposity and physical fitness with performance in the Supine-to-Stand test (STS-test) in sedentary adolescents. Methods: Sixty-two adolescents, of both sexes, between 10 and 16 years old, participated in the study. Body mass (BM), height, waist circumference (WC), fat mass (FM), fat-free mass (FFM), right and left handgrip strength (HGS-right, HGS-left), abdominal resistance (ABDO), flexibility (FLEX), and cardiorespiratory fitness (VO2peak) were measured. Body mass index (BMI), z-score BMI (BMI-z), tri-ponderal mass index (TMI) and waist-to-height ratio (WHtR) were calculated. The STS-test was applied to evaluate the STS-MC by the movement patterns in the execution of the test. The STS-time in seconds (s) was categorized into terciles: fast (FG < 2.0 s), intermediate (IG = 2.0-2.6 s) and slow (SG > 2.6 s). One-way ANOVA, Chi-square, Spearman's correlation coefficient as well as non-parametric tests were used, with significance p 0.05. Results: The SG presented higher BMI, BMI-z, TMI, WHtR, FM, %FM, as well as lower averages for %FFM, HGS-right, HGS-left, FLEX, ABDO, VO2peak, VO2peak relative to BM (VO2peakBM) in relation to GF. The BMI, BMI-z, TMI, WC, WHtR and FM showed moderate and direct correlations with STS-time and inverse with STS-MC (p < 0.01). HGS-right, HGS-left, ABDO, and VO2peakBM showed moderate and an inverse correlation with STS-time (p < 0.05). The VO2peakBM was moderate and with direct correlations to STS-MC (p < 0.01). Conclusion: It is concluded that excess fat and low physical fitness hamper STS-test performance. Therefore, the STS-test can be used for screening students to assess MC.

Fatores relacionados à capacidade física de membros superiores e inferiores de idosos quilombolas / Factors related to the physical capacity of upper and lower limbs in quilombola elderly people

Resumo Objetivou-se avaliar os fatores relacionados à capacidade física de membros superiores e inferiores em idosos quilombolas. Estudo transversal e analítico, realizado com a população idosa residente na comunidade quilombola Caiana dos Crioulos, Alagoa Grande, estado da Paraíba. As variáveis dependentes investigadas foram capacidade física de membros superiores e de membros inferiores. Foi realizada correlação de Spearman e regressão linear simples e múltipla (IC95%; p<0,05). O estudo foi realizado em conformidade com a Resolução 466/2012 do Conselho Nacional de Saúde do Ministério da Saúde. Foram avaliados 43 idosos. A análise bivariada mostrou correlação positiva entre FPM e PAF; entre FPM e CMB e correlação inversa entre a SPPB e a idade. O modelo múltiplo para FPM mostrou correlação significativa com a idade, CMB e anos de estudo (R2=0,374; p<0,05). Para a SPPB mostrou correlação significativa com a idade (R2=0,2524; p=0,001). Assim, a reserva de massa muscular, anos de estudo e idade foram fatores relacionados à capacidade física entre os idosos quilombolas. A observância criteriosa destes aspectos e a intervenção precoce podem preservar a capacidade física e garantir a inclusão produtiva e a autonomia econômica tão pleiteada na agenda social das comunidades.

Abstract This paper aimed to assess the factors related to the physical capacity of upper and lower limbs in quilombola older adults. This is a cross-sectional, analytic study performed with elderly residents in the quilombola community Caiana dos Crioulos, Alagoa Grande, Paraíba, Brazil. The researched dependent variables were the physical capacity of upper and lower limbs. It was performed the Spearman correlation and multiple and linear simple regression (95% CI; p<0.05). This work was performed per Resolution 466/2012 from National Health Council. Forty-three older adults were assessed. The bivariate analyses showed a positive correlation between handgrip strength (HGS) and physical activity (PA), between HGS and arm muscle circumference (AMC), and an inverse correlation between Short Physical Performance Battery (SPPB) and age. The multiple-model for HGS was significantly correlated with age, AMC, and years of study (R2=0.374; p<0.05). Regarding the SPPB, it showed a significant correlation with age (R2=0.2524; p=0.001). Therefore, the muscle mass reserve, years of study, and age were factors related to the physical capacity among quilombola older adults. The strict compliance of these aspects and the early intervention can preserve physical capacity and ensure the productive inclusion and economic autonomy so much sought in the communities' social agenda.

Fuerza de prensión manual y calidad de vida en personas mayores autovalentes / Hand grip strength and quality of life in functional elderly

Introducción: Durante el envejecimiento se observa involución de algunos sistemas corporales. Entre estos cambios, los que afectan al sistema osteomuscular como la sarcopenia y la debilidad muscular, pueden alterar el desarrollo de actividades de la vida diaria, y por lo tanto, afectar la calidad de vida relacionada con la salud. Objetivo: Determinar la relación entre la fuerza de prensión manual y la calidad de vida relacionada con la salud en personas mayores. Métodos: Estudio descriptivo, correlacional. Evaluó 79 personas mayores (63 mujeres y 16 hombres) entre 65 y 78 años, de tres organizaciones sociales de la ciudad de Talca, Chile, seleccionados a través de un muestreo no probabilístico por conveniencia. Para medir la fuerza de prensión manual se utilizó un dinamómetro de mano y el cuestionario SF-36 fue usado para valorar la calidad de vida relacionada con la salud. Resultados: Se observaron relaciones significativas entre la fuerza de prensión manual y las dimensiones de la calidad de vida función física (p = 0,03; r = 0,76), dolor corporal (p = 0,01; r = 0,44) y salud general (p = 0,05; r = 0,48). Conclusiones: Existe relación entre la fuerza de prensión manual y tres dimensiones de la calidad de vida relacionada con la salud de personas mayores. Estos hallazgos corroboran la relevancia de evaluar la fuerza muscular en personas mayores como un marcador de salud y calidad de vida en estas(AU)

Introduction: During aging, involution of some body systems is observed. Among these changes, those that affect the musculoskeletal system such as sarcopenia and muscle weakness can alter the development of activities of daily life, and therefore affect health-related quality of life. Objective: to determine the relationship between hand grip strength and quality of life in elderly. Methods: Cross-sectional study. A total of 79 elderly (63 women and 13 men) between 65 and 78 years of age from three social organizations of Talca, Chile was included. A non-probabilistic convenience sample was used. To measure manual grip strength and the SF-36 questionnaire was used. Results: Significant relationships between hand grip strength and dimensions of quality of life, physical function (p = 0,03; r = 0,76), body pain (p = 0,01; r = 0,44) and general health (p = 0,05; r = 0,48) were observed. Conclusions: There is a relationship between hand grip strength and three measurements of quality of life in elderly. These findings corroborate the relevance of evaluating muscle strength in older people as a marker of health and quality of life in elderly(AU)
