Introduction: Individuals with chronic kidney disease (CKD) undergoing hemodialysis (HD) present low cardiorespiratory fitness and functional capacity. Metabolic changes, due to the disease, can result in a variety of pathophysiological conditions that favor the development of respiratory muscle weakness. However, very little is known about the performance of the respiratory muscles and the influence of HD on them. Aim: To evaluate and correlate pulmonary function, functional capacity and respiratory muscle strength in patients with CKD undergoing HD. Methods: Cross-sectional study comprising 23 patients with CKD, that met the following inclusion criteria: patients of both genders, who perform HD three times a week for a minimum period of three months. Respiratory muscle strength was evaluated using a respiratory pressure meter, lung function through spirometry and functional capacity through the 6-minute walk test (6MWT) before the HD session. Results: All patients were male and mean age was 50.2 ± 15.8 years. The median duration of HD was 3 (1.5 to 6.0) years. The mean values obtained in comparison to those predicted were MIP% 36.0 ± 13.6, MEP% 49.5 ± 15.8, FVC% 93.8 ± 21.1, FEV1% 93.7 ± 21.1, FVC/VEF1% 104.1 ± 10.3, and 6MWT% 66.33 ± 20.53. A statistically significant positive correlation was observed between the 6MWT and MIP (r = .63, p =.001) and MEP (r = .67, p < .001), between the MIP and MEP (r =.79, p < .001) and between the FEV1 and FVC (r = .91, p < .001). Conclusion: Patients with CKD undergoing HD present changes in respiratory muscle strength, with the predicted values decreasing for age and gender, as well as the distance covered in the 6MWT, although, with normal spirometric values. Functional capacity was dependent on respiratory muscle strength, as well as the values of MIP and MEP, and the values of FVC and FEV1.

RESUMEN | Este estudio tiene por objeto revisar sistemáticamente los efectos en el tratamiento con la práctica de ejercicios físicos aerobios, resistivos o combinados (resistido/aerobio/equilibrio) en el equilibrio, en la fuerza muscular y el índice de la glucemia de sujetos con neuropatía diabética. Se llevó a cabo una búsqueda de estudios clínicos controlados en los que fueron empleados ejercicio aerobio, ejercicio resistido o ejercicio combinado en sujetos con neuropatía diabética comparados con un grupo control en las siguientes bases de datos: MEDLINE (vía PubMed), Cochrane CENTRAL, LILACS (vía Bireme) y PEDro. Se consideraron los términos: equilibrio, evaluación desde la escala AB, índice de la glucemia a través del valor de la glucemia en ayuno y después de la comida, y la fuerza muscular, evaluada según la dinamometría y el test Five-times-sit-to-stand. De los 389 estudios encontrados, se incluyeron cinco, con un total de 292 sujetos. Se observó que el ejercicio combinado (resistido/equilibrio) comparado con el del control presentó una significativa mejora en el equilibrio (8; IC 95%: 1,12 a 14,88; I2=0%). De estos cinco estudios incluidos, dos evaluaron la fuerza muscular de MMII (n=116), ambos estudios con ejercicios combinados (resistido/equilibrio) versus control, sin embargo no se realizó el metaanálisis, debido a que se evaluó la fuerza muscular de distintas formas. Solamente un estudio evaluó el índice de la glucemia después de la comida y en ayuno (n=87), por lo que impidió el metaanálisis. En dicho estudio, el índice de la glucemia después de la comida y en ayuno, cuando comparados en los dos grupos, no presentaron diferencias significativas. Los datos evaluados en esta revisión mostraron que el equilibrio en pacientes con neuropatía diabética presentó una mejora durante la práctica de ejercicios combinados.Palabras clave | Neuropatías Diabéticas; Ejercicio; Ensayo Clínico.

Introdução: A expectativa de vida de pessoas com câncer metastático está aumentando, mas esse grupo de pacientes corre um risco considerável de apresentar problemas psicológicos e de saúde física. Nesse sentido, o exercício físico tem sido um aliado no tratamento de pacientes com metástases ósseas. Objetivo: Realizar uma revisão sistemática e metanálise sobre a segurança e os benefícios do exercício físico em pacientes com metástases ósseas. Método: Metanálise com pesquisa bibliográfica realizada nas bases eletrônicas: PubMed, LILACS, PEDro e Embase. Resultados: Dos 396 estudos, somente dez foram incluídos, com um total de 531 indivíduos. Não foi observado nenhum efeito adverso musculoesquelético durante a intervenção, sendo significativamente seguro o exercício em indivíduos com metástases ósseas. Não houve melhora considerável na capacidade aeróbica, progressão da doença, qualidade de vida, massa magra e gordura corporal. Três dos estudos incluídos avaliaram a dor durante e após a intervenção, demonstrando melhora no escore de dor, assim como a diminuição do uso do analgésico no grupo intervenção. Conclusão: A terapia com exercícios aeróbicos e isométricos e segura para pacientes com metástases ósseas, além de apresentar melhora da dor, mas sem evolução relevante na capacidade aeróbica, na progressão da doença, na massa corporal e na qualidade de vida.

This scoping review sought to identify, synthesize, and assess the available evidence on the aims and effects of interventions used by health professionals in older adults with low levels of health literacy. Relevant articles were selected from the databases from April 2017 to April 2020. The Joanna Briggs Institute Manual for Evidence Synthesis was used for conducting this scoping review, and a total of 22 studies were reviewed. The positive effects observed for each type of intervention, yielding significant results for some of the outcomes and improvements in intragroup scores, demonstrated that the interventions had good acceptability by older adults with limited health literacy. However, we were not able to determine which intervention strategies had a significant positive effect on health outcomes in these patients. Further highquality randomized clinical trials employing greater methodological rigor for assessing results are needed to elucidate the potential benefits of interventions in this population.
