RESUMO

BACKGROUND AND PURPOSE: Diminished pulmonary function is associated with negative health outcomes and pulmonary impairment, and can be associated with frailty. The objectives of this study were to compare pulmonary function between frail, prefrail, and nonfrail older adults; to verify the association between pulmonary function and frailty syndrome; and to establish cut-off points for pulmonary function variables for predicting frailty. METHODS: A cross-sectional study was conducted with 379 community-dwelling older adults of both sexes. Spirometry was used to measure pulmonary function criteria (forced vital capacity, FVC; forced expiratory volume in 1 second, FEV 1 ; and FEV 1 /FVC ratio). The presence of frailty was evaluated with Fried's frailty phenotype. Statistical analysis included a multinomial logistic regression model. Pulmonary function cut-off points for discriminating frailty syndrome were established through analysis of the receiver operating characteristic curves. RESULTS AND DISCUSSION: The study participants were a median of 69.0 (64.0-74.0) years old, and 12.4% presented frailty while 58% presented prefrailty. Frail and prefrail older adults presented significantly lower median FVC and FEV 1 values-FVC = 1.89 L (1.45-2.31) and FEV 1 = 1.60 L (1.24-1.91); FVC = 2.07 L (1.62-2.67) and FEV 1 = 1.66 L (1.32-2.09), respectively-than nonfrail participants-FVC = 2.53 L (1.96-3.16) and FEV 1 = 2.01 L (1.54-2.43). The adjusted analysis indicated that FEV 1 (odds ratio [OR] = 0.63; 95% confidence interval [CI], 0.39-0.99) and the FVC (OR = 0.68; 95% CI, 0.48-0.96) were inversely associated with prefrailty and that FVC (OR = 0.52; 95% CI, 0.29-0.94) was associated with frailty. Cut-off points for prefrailty (FVC ≤2.3 L and FEV 1 ≤1.86 L) and frailty (FVC ≤2.07 L and FEV 1 ≤1.76 L) were established. CONCLUSIONS: Pulmonary function was lower in frail and prefrail older adults than in their nonfrail peers. Frailty and prefrailty were inversely associated with pulmonary function. Cut-off points for FEV 1 and FVC for discriminating frailty were established and may allow pulmonary function to serve as an indicator of frailty in older adults.

RESUMO

PURPOSE: No studies have previously analyzed the association between dynapenic abdominal obesity (DAO) and pulmonary function in older adults. The aim of this study was to analyze whether there is an association between pulmonary function and abdominal obesity, dynapenia, and DAO in community-dwelling older adults. METHODS: A cross-sectional study was conducted with community-dwelling older adults (n = 383) of Macapá, Amapá, Brazil. Pulmonary function variables were evaluated with spirometry; and DAO was evaluated with the combination of dynapenia and abdominal obesity. Cutoff points for handgrip strength, 26 kg force for men and 16 kg force for women, were used to detect dynapenia; and cutoff points of abdominal circumference of > 102 cm for men and > 88 cm for women were used to identify abdominal obesity. RESULTS: Most of the studied pulmonary function variables (obtained values and obtained versus predicted values) were associated with abdominal obesity, dynapenia, and DAO. However, in the adjusted model, there was an association of FVC (ß = - 0.163; p < 0.001), FEV1 (ß = - 0.119; p = 0.006), and PEF (ß = - 0.110; p = 0.017) only with dynapenia. CONCLUSIONS: Older adults with abdominal obesity, dynapenia, and DAO presented impaired pulmonary function when compared to those without these conditions. Most of the pulmonary function variables were associated with abdominal obesity, dynapenia, and DAO conditions. However, in the adjusted model, there was an association of reduced FVC, FEV1, and PEF values only with dynapenia.

RESUMO

The pandemic caused by SARS-CoV-2 that leads to COVID-19 has had an incalculable impact on society, services, and health professionals, including physiotherapists. The field of physiotherapy is currently facing ongoing challenges and pandemic-related repercussions, with Brazilian physiotherapists being especially affected. This article describes the current scenario in Brazil which has exposed the shortage of professionals and resources and reinforces the need for professional recognition, especially of those working in intensive care units. Barriers and challenges faced by Brazilian physiotherapists during the COVID-19 pandemic are described, followed by innovative solutions. Remote physiotherapy prior to the pandemic was merely one of many patient care options, but now has become a necessity, and several international organizations have provided guidelines for physiotherapists to follow, including guidelines on offering digital physiotherapy. Related demands, challenges, and perspectives of physiotherapy practice are likely to emerge amid the current uncertainties of the COVID-19 crisis, as well as during the post-pandemic period. The lessons learned by the Brazilian physiotherapy community may be of assistance to physiotherapists in other countries particularly those with comparable social and demographic characteristics.

RESUMO

OBJECTIVES: To compare obtained and predicted inspiratory and expiratory muscle strength between frail, pre-frail, and non-frail older people; to examine the association between inspiratory and expiratory muscle strength and frailty in older people; and to determine cut-off points for inspiratory and expiratory muscle strength for discriminating frailty in older people. METHODS: A cross-sectional study was conducted with 379 community-dwelling older adults. Frailty was assessed using Fried's phenotype, while inspiratory and expiratory muscle strength were measured with maximum inspiratory and maximum expiratory pressures. Inferential analyses were performed using paired Student t-tests, one-way analysis of variance (ANOVA) tests, and a multinomial logistic regression model. ROC curves were constructed to establish cut-off points of maximum inspiratory and expiratory pressures for discriminating frailty and pre-frailty. RESULTS: Frail and pre-frail participants presented significantly lower mean inspiratory and expiratory pressures compared to non-frail participants; values were significantly lower than predicted. Inspiratory and expiratory muscle strength were inversely associated with frailty and pre-frailty. Cut-off points ≥-50cmH2O and ≤60cmH2O for maximum inspiratory and expiratory pressures, respectively, were established as optimal discriminators of frailty. The cut-off point ≤65cmH2O for maximum expiratory pressure was established as a discriminant for the presence of pre-frailty. CONCLUSIONS: Inspiratory and expiratory muscle strength were lower in frail than in pre-frail older adults, and lower in pre-frail than in non-frail peers. Frailty and pre-frailty were inversely associated with inspiratory and expiratory muscle strength. Cut-off points for inspiratory and expiratory muscle strength may be useful in clinical practice for discriminating frailty and pre-frailty in older adults.

RESUMO

BACKGROUND: Sickle Cell Disease (SCD), which is characterized by a mutation in the gene encoding beta hemoglobin, causes bodily dysfunctions such as impaired pulmonary function and reduced functional capacity. OBJECTIVE: To assess changes in pulmonary function and functional capacity in patients with SCD and to identify the relationships between these variables. METHOD: We evaluated sociodemographic, anthropometric, lung function (spirometry), respiratory (manovacuometer), peripheral muscle strength (Handgrip strength - HS) and functional capacity (i.e., the six-minute walk test) parameters in 21 individuals with SCD (average age of 29±6 years). Shapiro-Wilk, paired Student's, Wilcoxon, Pearson and Spearman correlation tests were used for statistical analyses, and the significance threshold was set at p<0.05. RESULTS: A total of 47.6% of the study subjects exhibited an altered ventilation pattern, 42.8% had a restrictive ventilatory pattern (RVP) and 4.8% exhibited a mixed ventilatory pattern (MVP). The observed maximal inspiratory pressure (MIP) values were below the predicted values for women (64 cmH2O), and the maximum expiratory pressure (MEP) values, HS values and distance walked during the 6MWT were below the predicted values for both men (103 cmH2O, 39 Kgf and 447 m, respectively) and women (64 cmH2O; 27 Kgf; 405 m, respectively). Positive correlations were observed between maximum voluntary ventilation (MVV) and MEP (r=0.4; p=0.046); MVV and BMI (r=0.6; p=0.003); and between HS and MIP (r=0.7; p=0.001), MEP (r=0.6; p=0.002), MVV (r=0.5; p=0.015), distance walked in the 6MWT (r=0.4; p=0.038) and BMI (r=0.6; p=0.004). CONCLUSIONS: SCD promoted changes in lung function and functional capacity, including RVPs and a reduction in the distance walked in the 6MWT when compared to the predictions. In addition, significant correlations between the variables were observed.

RESUMO

BACKGROUND: Sickle cell disease is a prevalent condition in Brazil. Its clinical presentation includes vascular occlusion that result in ischemia, inflammation, dysfunctions, pain and chronic hemolysis, causing irreversible damage and compromising quality of life. OBJECTIVE: The objectives of this study were to verify the relationship between musculoskeletal pain, from different body parts, with social economic characteristics and quality of life among individuals with sickle cell disease. METHODS: 27 individuals with sickle cell disease were interviewed with the use of a structured questionnaire with questions about personal, social, economic and cultural variables, the Nordic musculoskeletal symptoms questionnaire and the SF-36 Health Survey. Data were analyzed descriptively using frequencies and percentages. The inferential Chi-Square test was used for dichotomous variables and the Student t- test for continuous variables, with a significance of 5%. A logistic regression was performed using all variables that correlated with pain as dependent variables. RESULTS: The mean age was 31.77 years, predominantly male, black, registered active employment, with average education and income up to three minimum wages. The regions most affected by pain were hip/limbs, chest, lower back and arms. Physical Functioning from the SF-36 had the highest score and mental health the lowest score. Musculoskeletal pain was present in the arms, chest and lower back. Social Functioning was not associated with pain, indicating the influence of other factors. Arm pain was more frequent in black individuals and those with low education. CONCLUSION: Body pain was associated with race and education and all pain areas were associated with the physical components of the SF-36. Pain was significantly associated with vitality and mental health components of the SF-36.

CONTEXTUALIZAÇÃO: As doenças falciformes constituem um grupo frequente no Brasil. Suas alterações ocasionam vaso-oclusão, resultando em isquemia, inflamação, disfunções, dor e hemólise crônica, gerando danos irreversíveis, comprometendo a qualidade de vida. OBJETIVO: Verificar a relação entre a dor osteomuscular, considerando sua localização corporal, e características sociais, econômicas e de qualidade de vida em indivíduos com doença falciforme. MÉTODOS: Foram coletadas informações pessoais, sociais e econômicas, além de dados do Questionário Nórdico de Sintomas Osteomusculares (QNSO) e Short Form 36 em 27 indivíduos. Os dados foram analisados descritivamente por meio de frequências e porcentagens. A análise inferencial usou o teste do qui-quadrado (variáveis dicotômicas) e t de Student (variáveis contínuas), com significância de 5%. Análises de regressão logística utilizaram como variáveis dependentes cada uma das que se relacionaram com dor. RESULTADOS: A média de idade foi de 31,77 anos, predominando sexo masculino, negros, emprego ativo, escolaridade média e rendimento inferior a três salários mínimos. Quadril/membros inferiores, região dorsal, lombar e braços foram mais acometidos pela dor. A capacidade funcional apresentou o maior valor, e saúde mental, o menor. Aspectos físicos foram comprometidos pela dor nos braços, coluna dorsal e lombar. Aspectos sociais não se associaram com a dor, indicando influência de outros fatores. A dor nos braços foi mais frequente entre os negros e os com baixa escolaridade. CONCLUSÃO: A dor nas regiões corporais analisadas relacionou-se com a raça e a escolaridade e com todos os domínios referentes ao componente físico do SF-36. Os componentes vitalidade e saúde mental apresentaram associação significativa com a dor.
