Advanced glycation end products consumption and the decline of functional capacity in patients with Parkinson's disease: Cross-sectional study

Abstract Introduction Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities. Methods This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C). The autofluorescence reader was used to evaluate skin AGEs, while food recall was used to quantify AGEs consumed for three different days. The Montreal Cognitive Assessment, Short Physical Performance Battery, and handgrip tests were used. PD patients demonstrated greater impairment in functional capacity compared to the control group. Results Dominant Handgrip (p = 0.02) and motor performance, in the sit and stand test (p = 0.01) and Short Physical Performance Battery (SPPB) (p = 0.01) were inferior in PD patients than the control group. Although PD patients tended to consume less AGEs than the control group, AGE intake was negatively correlated with handgrip strength in individuals with PD (r = -0.59; p < 0.05). Conclusion PD patients had lower strength and functional capacity, suggesting that the effects of AGEs might be exacerbated during chronic diseases like Parkinson's.

A pilot observational study to identify reference values for the 6-minute walk test in Brazilian people with hypertension / Um estudo observacional piloto para identificar valores de referência para o teste de caminhada de 6 minutos em hipertensos brasileiros

Abstract Introduction Systemic arterial hypertension (SAH) is responsible for 9.5 million deaths in the global popu-lation. Lifestyle factors, including physical inactivity, are important modifiable risk factors in the development of SAH. Thus, physical exercise has been shown to be effective to control SAH and before the prescription, the six-minute walk test (6-MWT) has been commonly used to assess the physical capacity. Objective To propose reference values for the 6-MWT test in Brazilian people with SAH. Methods A cross-sectional observational study was conducted with 302 hypertensive subjects (62.61 + 10.93 years) admitted to a cardiac rehabilitation program. Participants were divided into different age quartiles and submitted to 6-MWT. The walking distance data was compared between the quartiles and adjusted by mul-tiple linear regression analysis. Results The hypertensive subjects walked 388.07 + 115.03 m during the 6-MWT. No significant difference between the genders was found. However, when the age quartiles were compared, for the 46-59 age group, the women walked less than the men. Intra-group comparisons showed that the distance walked in the 6-MWT decreased with the increase in age, in both men and women. Conclusion The present study provides reference values for the 6-MWT, both for Brazilian men and women of different age groups. This data may be an important parameter for future clinical studies, prevention strategies, and clinical intervention.

Resumo Introdução A hipertensão arterial sistêmica (HAS) é respon-sável por 9,5 milhões de mortes na população mundial. Con-dições do estilo de vida, incluindo a inatividade física, são importantes fatores de risco modificáveis no desenvolvimento da HAS. Desse modo, o exercício físico tem se mostrado eficaz no controle da HAS e, antes da prescrição, o teste de caminhada de seis minutos (TC6) tem sido comumente utilizado para ava-liar a capacidade física. Objetivo Propor valores de referência para o teste de TC6 em brasileiros com HAS. Métodos Realizou-se um estudo observacional transversal com 302 hipertensos (62,61 + 10,93 anos) admitidos em um programa de reabilitação cardíaca. Os participantes foram divididos em diferentes quartis de idade e submetidos ao TC6. Os dados de distância percorrida foram comparados entre os quartis e ajustados por análise de regressão linear múltipla. Resultados Os hipertensos caminharam 388,07 + 115,03 m durante o TC6. Não encontrou-se diferença significativa entre os gêneros. No entanto, quando comparados os quartis de idade, para a faixa etária de 46 a 59 anos, as mulheres caminharam menos do que os homens. As comparações intragrupo mostraram que a distância percorrida no TC6 diminuiu com o aumento da idade, tanto em homens quanto em mulheres. Conclusão O presente estudo fornece valores de referência para o TC6, tanto para homens quanto para mulheres brasileiras de diferentes faixas etárias. Esses dados podem ser um parâmetro importante para futuros estudos clínicos, estratégias de prevenção e intervenção clínica.

Efficacy of Respiratory Muscle Training in the Immediate Postoperative Period of Cardiac Surgery: A Systematic Review and Meta-Analysis

ABSTRACT Introduction: This study aimed to evaluate the efficacy of respiratory muscle training during the immediate postoperative period of cardiac surgery on respiratory muscle strength, pulmonary function, functional capacity, and length of hospital stay. Methods: This is a systematic review and meta-analysis. A comprehensive search on PubMed®, Excerpta Medica Database (or Embase), Cumulative Index of Nursing and Allied Health Literature (or CINAHL), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Physiotherapy Evidence Database (or PEDro), and Cochrane Central Register of Controlled Trials databases was performed. A combination of free-text words and indexed terms referring to cardiac surgery, coronary artery bypass grafting, respiratory muscle training, and clinical trials was used. A total of 792 studies were identified; after careful selection, six studies were evaluated. Results: The studies found significant improvement after inspiratory muscle training (IMT) (n = 165, 95% confidence interval [CI] 9.68, 21.99) and expiratory muscle training (EMT) (n = 135, 95% CI 8.59, 27.07) of maximal inspiratory pressure and maximal expiratory pressure, respectively. Also, IMT increased significantly (95% CI 19.59, 349.82, n = 85) the tidal volume. However, no differences were found in the peak expiratory flow, functional capacity, and length of hospital stay after EMT and IMT. Conclusion: IMT and EMT demonstrated efficacy in improving respiratory muscle strength during the immediate postoperative period of cardiac surgery. There was no evidence indicating the efficacy of IMT for pulmonary function and length of hospital stay and the efficacy of EMT for functional capacity.

Conclusiones: La depresión es un factor independiente para discapacidad funcional en pacientes con fibromialgia.

Background: Fibromyalgia is a rheumatological disorder characterized by generalized pain of imprecise localization that mainly affects women. It is associated with fatigue, anxiety, depression, and functional capacity is greatly affected by the coexistence of these disorders. Methods: It is a series of cross-sectional cases, using secondary data from 126 patients with fibromyalgia who attended the outpatient clinic of a hospital at Lima at the rheumatology service during February 2020. We try to determine the frequency of functional disability and explore associated factors in patients diagnosed with fibromyalgia with or without depression. Functional capacity and the presence of depressive symptoms were measure by validated scales. A multivariate multiple logistic regression analysis was performed to assess whether depression is an independent risk factor for disability. Results: The age had a median of 53.5 (IQR: 46-60) years, 122 participants were women. In addition, 42 (33.33%) patients had depression and 76 (60.32%) patients had functional disability. In the multivariate analysis, it was found that depression is an independent risk factor for functional disability after adjusting for diabetes, presence of 3 or more comorbidities, intensity of fatigue and associated symptoms [OR 3.09 (1.24 - 7.70); p: 0.015]. Conclusions: Depression is an independent factor for functional incapacity in patients with fibromyalgia.

Associação entre indicadores da capacidade funcional e do estado nutricional em idosos da comunidade: uma nova abordagem / Association between functional capacity and nutritional status indicators in elderly community: a new approach

Resumo Introdução Alterações na composição corporal do idoso podem ser rapidamente identificadas por profissionais de saúde na Atenção Básica, reduzindo o impacto sobre a saúde, o estado nutricional e a capacidade funcional. Objetivo Identificar relações entre massa e força muscular com o estado nutricional e a capacidade funcional em idosos da comunidade. Método Estudo transversal, envolvendo 323 idosos. A avaliação da composição corporal foi realizada por absorciometria (DEXA) e antropometria. A capacidade funcional foi avaliada pelas Atividades Instrumentais de Vida Diária, pela velocidade da marcha (VM) e Time Up and Go (TUG). Resultados Nesta amostra, o índice de massa magra (IMM) se mostrou associado aos indicadores do estado nutricional (IMC, CP e CC), além de ter apresentado importante correlação com a força de preensão palmar (FPP). A FPP esteve relacionada à VM e ao TUG. A análise de regressão identificou associação entre o IMC e o IMM (p<0,001), bem como entre a VM e a FPP (p=0,003). Conclusão A FPP se apresentou como importante indicador da capacidade funcional e se mostrou correlacionada com o IMM. Consequentemente, o IMM está associado aos indicadores do estado nutricional. Logo, na impossibilidade de avaliação do IMM, recomendamos a avaliação da FPP, CP e IMC como preditores de comprometimento do estado nutricional e da incapacidade funcional do idoso.

Abstract Background Changes in the body composition of the elderly can be quickly identified by health professionals in primary care, reducing the impact on health, nutritional status, and functional capacity. Objective To look for links between muscle mass and strength, nutritional status, and functional capacity in community-dwelling elderly. Method A cross-sectional study involving 323 elderly people was carried out. Body composition assessment was performed by absorptiometry (DEXA) and anthropometry. Functional capacity was assessed by Instrumental Activities of Daily Living and by gait speed (VM) and Time Up and Go (TUG). Results In this sample, the lean mass index (LMI) was associated with indicators of nutritional status (BMI, NC, and WC), in addition to having shown an important correlation with handgrip strength (HGS). HGS was associated with VM and TUG. Regression analysis identified an association between BMI and LMI (p < 0.001) and between GS and HGS (p = 0.003). Conclusion HGS was an important indicator of functional capacity and correlated with LMI. Consequently, the LMI is associated with indicators of nutritional status. Therefore, when it is impossible to assess the LMI, we recommend the assessment of HGS, NC and BMI as predictors of compromised nutritional status and functional disability in the elderly.

Respiratory oscillometry and functional analyses in patients with idiopathic scoliosis

Scoliosis is a condition that affects the spine and causes chest rotation and trunk distortion. Individuals with severe deformities may experience dyspnea on exertion and develop respiratory failure. Respiratory oscillometry is a simple and non-invasive method that provides detailed information on lung mechanics. This work aims to investigate the potential of oscillometry in the evaluation of respiratory mechanics in patients with scoliosis and its association with physical performance. We analyzed 32 volunteers in the control group and 32 in the scoliosis group. The volunteers underwent traditional pulmonary function tests, oscillometry, and the 6-minute walk test (6MWT). Oscillometric analysis showed increased values of resistance at 4 Hz (R4, P<0.01), 12 Hz (R12, P<0.0001), and 20 Hz (R20, P<0.01). Similar analysis showed reductions in dynamic compliance (Cdyn, P<0.001) and ventilation homogeneity, as evaluated by resonance frequency (fr, P<0.001) and reactance area (Ax, P<0.001). Respiratory work, described by the impedance modulus, also showed increased values (Z4, P<0.01). Functional capacity was reduced in the group with scoliosis (P<0.001). A significant direct correlation was found between Cobb angle and R12, AX, and Z4 (P=0.0237, P=0.0338, and P=0.0147, respectively), and an inverse correlation was found between Cdyn and Cobb angle (P=0.0190). These results provided new information on respiratory mechanics in scoliosis and are consistent with the involved pathophysiology, suggesting that oscillometry may improve lung function tests for patients with scoliosis.

The PAY test: a new approach for assessing functional performance in children and adolescents with asthma

Abstract Objective: To develop, validate, and test the reproducibility of a new test capable of assessing functional performance in children and adolescents (PAY test: Performance Activity in Youth). Methods: participants without and with asthma were included in the development and validation phases, respectively. The PAY test includes five activities: transition from sitting to standing, walking 10 m, step climbing, shoulder extension and flexion, and star jumps. Participants underwent the Pediatric Glittre test (TGlittre-P test time), modified shuttle test (MST), and cardiopulmonary exercise test (CPET). Outcomes: PAY test and TGlittre-P test times, oxygen uptake (VO2peak), and distance walked in the MST. Results: 8 healthy volunteers, aged 12 (7 -15) years old were included in the development phase and 34 participants with asthma, aged 11 (7-14) years old, in the validation phase. The PAY test elicited greater physiological responses (VO2peak 33.5 ± 6.9 mL/kg) than the TGlittre-P (VO2peak: 27.4 ± 9.0 mL/kg), but lower than the MST (VO2peak: 48.9 ± 14.2 mL/kg) and CPET (VO2peak: 42.0 ± 8.8 mL/kg), p < .05. Moderate correlation between the PAY test time and the TGlittre-P time (r = 0.70, p < .001) and distance walked in the MST (r = -0.72, p < .001). The PAY test time was longer in participants with asthma than in healthy participants (3.1 [3.0 - 3.3] min vs. 2.3 [2.1 - 2.4 min]), p < .001.; and the test was reproducible (ICC 0.78, CI 95% 0.55-0.90, p < .001). Conclusions: The PAY test is a valid and reproducible tool for assessing functional performance in children and adolescents with asthma.

Effectiveness of functional training versus resistance exercise in patients with psoriatic arthritis: randomized controlled trial

Abstract Objective This study aims to evaluate the effect of functional versus resistance exercise training on the functional capacity and quality of life of psoriatic arthritis patients. Methods Forty-one psoriatic arthritis patients (18 to 65 years old) were randomized into two groups: functional training group and resistance exercise group. The functional training group underwent functional exercises with elastic band and the functional training group underwent machine resistance exercise twice a week for 12 weeks. Outcome measures were: The Bath Ankylosing Spondylitis Functional Index (BASFI) and Health Assessment Questionnaire for the Spondyloarthropathies (HAQ-S) for functional capacity and functional status, one-repetition maximum test for muscle strength, the Short Form 36 health survey questionnaire (SF-36) for quality of life, and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Disease Activity Score 28 (DAS-28) for disease activity. Analyzes were performed by a blinded evaluator at baseline (T0), six (T6) and twelve (T12) weeks after the beginning of the exercise. Results At baseline, the groups were homogeneous in the clinical and demographic characteristics. There was a statistical intra-group improvement for both groups in the BASFI, BASDAI, HAQ-s, and DAS-28. In the quality-of-life assessment, both groups showed statistical intra-group improvements for all domains except the "emotional aspect" domain in the resistance exercise group. In the muscle strength, there was a statistical improvement for all exercises in both groups, except for the "alternate biceps (bilateral)" exercise. Conclusion Functional training and resistance exercise are similarly effective in improving functional capacity, functional status, disease activity, general quality of life, and muscle strength in patients with psoriatic arthritis. Trial Registration ClinicalTrials.gov: NCT04304326. Registered 11 March 2020, https://clinicaltrials.gov/ct2/show/NCT04304326?term=NCT04304326&draw=2&rank=1.

Effects of a physiotherapeutic protocol in cardiorespiratory, muscle strength, aerobic capacity and quality of life after hematopoietic stem cell transplantation

Abstract Objective To analyze the effects of hospital cardiorespiratory physical therapy protocol on the functional capacity and quality of life of patients submitted to hematopoietic stem cell transplantation (HSCT). Methods From January to December 2019, bilateral dynamometry, Manovacuometry and Ventilometry, peak expiratory flow "Peak Flow", 6-min walk test (6MWT), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS) were applied in patients who have undergone an allogeneic or autologous hematopoietic stem cell transplantation (HSCT), pre-conditioning (initial evaluation) and pre-discharge (final evaluation). The patients were submitted to an intervention protocol, consisting of aerobic training, muscle strengthening and respiratory muscle training, between the two assessments. Results 29 patients were enrolled in the study and 24 (83%) completed all procedure. Myeloablative and reduced intensity conditioning were performed in 89.6% and 10.4%, respectively; 17 (58%) patients have undergone an autologous HSCT; 10 (35%) identical related allogeneic HSCT, and 2 (7%) haploidentical allogeneic HSCT. The median number of interventions per patient was 3 (1-9). A decreasing in the right and left dynamometry (p ≤ 0.0001 and 0.002, respectively) and, also in the distance covered in the 6MWT (p = 0.004), was observed after HSCT. There was no significant difference in respiratory muscle strength, quality of life and fatigue sensation. Conclusion Cardiorespiratory rehabilitation can preserve functional capacity and quality of life.

Interpretation of the international expert consensus guideline on exercise management for older adults / 中华老年医学杂志

Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiopulmonary fitness in older adults and may eventually lead to reduced capabilities to conduct daily activities and independent living.Exercise plays an important role in maintaining physical function and mental health, preventing and treating chronic diseases, reducing mortality, and improving the quality of life in older people.In 2021, the International Conference of Frailty and Sarcopenia Research(ICFSR)proposed international expert consensus guidelines on exercise recommendations for older people.It mainly introduces two aging phenotypes and six recommended exercise modalities and discusses the effects of exercise on maintaining physical health and preventing common chronic diseases and geriatric syndromes.It aims to provide suggestions for older adults to maintain physical fitness and prevent disease progression and disability via exercise.We intend to interpret the important contents of the guidelines to provide a reference for exercise research and practical applications in the elderly in China.

Prediction equation of peak oxygen uptake for the modified shuttle test in healthy adolescents / Equação de predição do consumo máximo de oxigênio para o shuttle test modificado em adolescentes saudáveis / Ecuación de predicción del consumo máximo de oxígeno para el shuttle test modificado en adolescentes sanos

ABSTRACT Given the gap in the literature regarding the peak of oxygen consumption (VO2peak) for adolescents of both sexes, this study aimed to propose an equation to predict the VO2peak in healthy adolescents using the Modified Shuttle Test (MST). This is a cross-sectional study with 84 healthy adolescents between 12 and 18 years old, female and male. The MST is an external paced test, in which the speed increases at each minute. Two MST were performed with at least 30 minutes of rest between them. The test with the longest walked distance was considered for analysis. VO2 was directly monitored by an open circuit spirometry. Mean age was 14.67±1.82 and the walked distance was 864.86±263.48m. Variables included in the prediction equation were walked distance and sex, explaining the VO2peak variability of 53% during MST performance. The prediction equation for VO2peak with the MST was: predicted VO2peak=18.274+(0.18×Distance Walked, meters)+(7.733×Sex); R2=0.53 and p<0.0001 (sex: 0 for girls, 1 for boys). This MST equation, proposed to predict VO2peak in healthy adolescents of both sexes, can be used as a reference to assess exercise capacity in healthy adolescents and to investigate cardiopulmonary function in adolescents with reduced functional capacity.

RESUMO Dada a lacuna na literatura quanto à equação de predição do pico de consumo de oxigênio (VO2) para adolescentes de ambos os sexos, o objetivo deste estudo é propor uma equação para predizer o VO2pico em adolescentes saudáveis utilizando o shuttle test modificado (MST). Trata-se de um estudo transversal realizado com 84 adolescentes saudáveis entre 12 e 18 anos, do sexo feminino e masculino. O MST é um teste de campo ditado por um sinal sonoro que indica o aumento da velocidade a cada minuto. Dois MSTs foram realizados com pelo menos 30 minutos de descanso entre eles. O teste com a maior distância percorrida foi o considerado para análise. O VO2 foi monitorado diretamente por uma espirometria de circuito aberto. A média de idade foi de 14,67±1,82 anos, e a de distância percorrida foi de 864,86±263,48m. As variáveis incluídas na equação de predição foram distância percorrida e sexo, que explicaram 53% da variabilidade do VO2pico durante a realização do MST. A equação de referência para o VO2pico previsto com o MST foi VO2pico predito=18,274+(0,18×Distância percorrida, em metros)+(7,733×Sexo); R2=0,53 e p<0,0001 (sexo: 0 para meninas, 1 para meninos). A equação do MST proposta para predizer o VO2pico em adolescentes saudáveis de ambos os sexos pode ser usada como referência para avaliar a capacidade de exercício em adolescentes saudáveis e investigar a função cardiopulmonar em adolescentes com capacidade funcional reduzida.

RESUMEN Dada una laguna en la literatura con respecto a la ecuación para predecir el consumo máximo de oxígeno (VO2) en adolescentes de ambos sexos, el objetivo de este estudio es proponer una ecuación para predecir el VO2máximo en adolescentes sanos usando el shuttle test modificado (MST). Se trata de un estudio transversal, realizado con 84 adolescentes sanos con edades entre 12 y 18 años, de ambos sexos. El MST es una prueba de campo dictada por una señal sonora que indica el aumento de velocidad cada minuto. Se realizaron dos MST con al menos 30 minutos de descanso entre ellos. Para el análisis se consideró la prueba con mayor distancia recorrida. El monitoreo del VO2 fue realizado directamente por espirometría de circuito abierto. La edad media fue de 14,67±1,82 años; y la distancia recorrida, de 864,86±263,48m. Las variables incluidas en la ecuación de predicción fueron la distancia recorrida y el sexo, que explicaron el 53% de la variabilidad del VO2máximo durante la realización del MST. La ecuación de referencia para el VO2máximo predicho con el MST fue VO2máximo previsto=18,274+(0,18×Distancia recorrida, en metros)+(7,733×Sexo); R2=0,53 y p<0,0001 (sexo: 0 para chicas, 1 para chicos). La ecuación MST propuesta para predecir el VO2máximo en adolescentes sanos de ambos sexos puede utilizarse como una referencia para evaluar la capacidad de ejercicio en adolescentes sanos y para investigar la función cardiopulmonar en adolescentes con capacidad funcional reducida.

Early Six-Minute Walk Test May Predict Midterm Outcomes Following Coronary Artery Bypass Grafting

ABSTRACT Objective: This study aims to investigate the ability of the six-minute walk distance (6MWD) as a prognostic marker for midterm clinical outcomes three months after coronary artery bypass grafting (CABG), to identify possible predictors of fall in 6MWD in the early postoperative period, and to establish the percentage fall in early postoperative 6MWD, considering the preoperative baseline as 100%. Methods: A prospective cohort of patients undergoing elective CABG were included. The percentage fall in 6MWD was assessed by the difference between preoperative and postoperative day (POD) five. Clinical outcomes were evaluated three months after hospital discharge. Results: There was a significant decrease in 6MWD on POD5 compared with preoperative baseline values (percentage fall of 32.5±16.5%, P<0.0001). Linear regression analysis showed an independent association of the percentage fall of 6MWD with cardiopulmonary bypass (CPB) and preoperative inspiratory muscle strength. Receiver operating characteristic curve analysis revealed that the best cutoff value of percentage fall in 6MWD to predict poorer clinical outcomes at three months was 34.6% (area under the curve = 0.82, sensitivity = 78.95%, specificity = 76.19%, P=0.0001). Conclusion: This study indicates that a cutoff value of 34.6% in percentage fall of 6MWD on POD5 was able to predict poorer clinical outcomes at three months of follow-up after CABG. Use of CPB and preoperative inspiratory muscle strength were independent predictors of percentage fall of 6MWD in the postoperative period. These findings further support the clinical application of 6MWD and propose an inpatient preventive strategy to guide clinical management over time.

Contexto en México, la enfermedad renal crónica presenta un aumento exponencial y el trasplante renal se ha colocado como la mejor opción de tratamiento. A pesar de ello, los receptores de trasplante presentan una menor capacidad funcional y calidad de vida comparándolos con individuos sanos, lo cual se asocia a un estilo de vida sedentario, sumado con los efectos musculoesqueléticos de los inmunosupresores, sin embargo, la investigación es limitada. Objetivo evaluar el impacto en calidad de vida, fuerza, resistencia aeróbica, equilibrio y flexibilidad de un programa domiciliario de ejercicio físico de intensidad leve-moderada, en pacientes adultos mexicanos trasplantados de riñón. Metodología participaron nueve pacientes (29 ± 5,2 años), a los cuales se les evaluó la fuerza de agarre manual mediante un dinamómetro; la flexibilidad mediante la prueba de "distancia dedos planta" (sit-and-reach test por su nombre en inglés); su agilidad-equilibrio y fuerza en miembro inferior mediante la prueba de "pararse-sentarse", y "levántate y anda" (sit-to-stand y get-up-and-go por sus nombres en inglés) respectivamente; su actitud cardiorrespiratoria mediante el test de marcha por seis minutos, y su calidad de vida mediante el cuestionario de salud SF36. Resultados se mostraron mejoras estadísticamente significativas en dinamometría manual (P 0,005), "distancia dedos planta" (P 0,016), sentarse y pararse (P 0,0011) y test de marcha por seis minutos (P 0,012). En el cuestionario SF36, hubo mejoría en la función física (P 0,03) y salud general (P 0,01), pero no hubo cambios en los análisis de laboratorio y la tasa de filtración glomerular. Conclusiones un programa domiciliario de ejercicio combinado de intensidad leve-moderada parece tener un efecto positivo sobre la capacidad funcional y la calidad de vida de los receptores de trasplante renal, sin embargo, es necesaria una mayor investigación para evaluar la adherencia al programa.

Pain, Stiffness and Functional Capacity Associated with Kinesiophobia in Patients with Knee Osteoarthritis, Hospital Nacional Hipolito Unanue, Peru / Dolor, rigidez y capacidad funcional asociados a la kinesiofobia en pacientes con artrosis de rodilla, Hospital Nacional Hipólito Unanue (Perú) / Dor, rigidez e capacidade funcional associados à cinesiofobia em pacientes com gonartrose, Hospital Nacional Hipólito Unanue, Peru

Introduction: The progressive and chronic characteristics of knee osteoarthritis imply the presence of symptoms, such as pain, stiffness, and functional capacity difficulty to varying degrees. However, asso-ciated psychosocial phenomena, such as kinesiophobia, may also arise, impeding the patient's recov-ery. The aim of this study is to determine the association among pain, stiffness, functional capacity, and kinesiophobia in patients with knee osteoarthritis at Hospital Nacional Hipolito Unanue, Peru, in the first two months of 2020. Materials and methods: An observational, correlational, cross-sectional study was conducted on 88 patients with knee osteoarthritis who were selected by census sampling. The Western Ontario and McMaster Universities Osteoarthritis Index questionnaire and the Tampa Scale for Kinesiophobia were used to measure pain, stiffness, functional capacity and kinesiophobia, respectively. Pearson's chi-square test (p < 0.01) was used for bivariate analysis. Results: The results showed a mean age of 66.38 years and a higher frequency in the female sex (68.2 %), current occupation without physical workload (56.8 %), secondary level education (40.9 %), time of illness of 1­5 years (51.1 %), bilateral lower limb involvement (68.18 %), moderate pain (51.1 %), moderate stiffness (51.1 %), functional capacity dif-ficulties (61.4 %), and a high level of kinesiophobia (60.2 %). A relationship was found between the vari-ables of pain, stiffness, and functional capacity associated with kinesiophobia (0.000). Conclusions: Pain, stiffness, and functional capacity are associated with kinesiophobia in patients with knee osteoarthritis. The degree of symptomatology increases with the increasing level of kinesiophobia.

Efeito do treinamento de força com diferentes velocidades de movimento sobre a capacidade funcional e qualidade de vida em idosos: uma revisão sistemática / Effect of resistance training with different movement speeds on functional capacity and quality of life in elderly: a systematic review

Uma das alternativas para manter o idoso ativo a fim de melhorar as capacidades funcionais e a qualidade de vida (QV) é o treinamento de força (TF). Porém, existem variáveis que devem ser consideradas na prescrição do TF como a velocidade de movimento. O objetivo do presente estudo foi realizar uma revisão sistemática para verificar o impacto de programas de TF realizados com diferentes velocidades de movimento na capacidade funcional e qualidade de vida em idosos saudáveis. Após seleção de artigos nas bases de dados Pubmed, Scopus e Web of Science foram encontrados 282 artigos, contudo, após a aplicação dos critérios de inclusão e exclusão foram considerados elegíveis 13 artigos para a revisão. Desses, 10 evidenciaram melhora na funcionalidade do grupo treinamento de força em alta velocidade (TFAV) ou resultado similar comparado ao treinamento tradicional (TT), dois encontraram resultados inalterados para ambos os grupos e um indicou que o grupo TT teve melhoras nos testes funcionais comparado ao TFAV. Quanto à QV, somente dois artigos avaliaram esta variável e foi observado resultado positivo utilizando o TFAV. Assim, foi observado que grande parte dos estudos sugere a realização do TFAV em detrimento do TT visando melhora ou manutenção da funcionalidade e QV. (AU)

One of the alternatives to keep the elderly active in order to improve functional capacities and quality of life (QL) is resistance training (RT). However, there are variables that should be considered in the prescription of RT as the speed of movement. The aim of the present study was to carry out a systematic review to verify the impact of RT programs carried out with different movement speeds on functional capacity and quality of life in healthy elderly people. After selecting articles in the Pubmed, Scopus and Web of Science databases, 282 articles were found, however, after applying the inclusion and exclusion criteria, 13 articles were considered eligible for review. Of these, 10 showed improvement in the functionality of the high-speed resistance training group (HSRT) or similar result compared to traditional training (TT), two found results unchanged for both groups and one indicated that the TT group had improvements in functional tests compared to HSRT. As for QL, only two articles evaluated this variable and a positive result was observed using HSRT. Thus, it was observed that most studies suggest the performance of HSRT at the expense of TT in order to improve or maintain functionality and QL. (AU)

Effects of multicomponent exercise training on the intrinsic capacity in frail older adults: review of clinical trials

Abstract Aim: To review the effects of multicomponent exercise training on the domains of the intrinsic capacity of physically frail older adults: locomotion, vitality, cognition, psychological outcomes, and sensory function. Methods: The search for the studies was carried out in the MEDLINE, Cochrane CENTRAL, and PEDro databases, along with manual search, delimiting the period of publication as the last 10 years. The initial search identified 338 studies and 18 among them were analyzed qualitatively. Results: From the analysis of the included studies, great variability was evidenced between the intervention protocols, as well as between the results. As for the effectiveness of multicomponent exercise training, it has been shown to induce a positive effect on most of the analyzed outcomes. Conclusion: In summary, the present review suggests that multicomponent physical training can be effective to improve aspects of locomotion, cognition, and psychological aspects in frail older populations. Nevertheless, more studies are needed to specify the time needed to achieve such adaptations, the magnitude of these adaptations, and the design of the most appropriate training program for each outcome related to intrinsic capabilities.

Acute whole-body electromyostimulation associated with dynamic exercises did not alter cardiac autonomic modulation and oxygen uptake in obese and eutrophic men

Abstract Aim: To contrast the acute effects of whole-body electromyostimulation (WB-EMS) with sham associated with dynamic exercises on cardiovascular, ventilatory, metabolic, and autonomic responses in men with obesity and controls. Methods: A randomized cross-over and double-blind trial with nine eutrophic (23.6 years; 23 ± 1.4 kg/m2) and ten men with obesity (26 ± 4 years; 38 ± 7 kg/m2), who were randomized to receive WB-EMS-Sham or Sham-WB-EMS with 30 min of rest between protocols. WB-EMS protocol (Miha Bodytec®) was applied at the motor level, frequency = 85 Hz, pulse duration = 350 μs, cycle on = 6′; cycle off = 4′. Sham group performed the same exercises with the electric current turned off. Throughout both protocols, subjects executed two dynamic exercises of 5 minutes each (step-up and step down associated with shoulder flexion, and lunge exercise associated with elbow flexion) in the same order. R-R intervals and breath-by-breath respiratory gases analysis were collected during the protocols. Heart rate variability (HRV) indexes were obtained using linear and nonlinear analysis. The level of statistical significance was set at p < 0.05. Results: Regarding both exercises, participants with obesity presented reduced oxygen uptake, higher ventilation, respiratory rate, blood pressure, and Borg scores (p < 0.05) when contrasted with controls, as expected. However, no significant differences were found for HRV indexes between groups (p > 0.05). In addition, WB-EMS did not increase oxygen uptake or altered autonomic modulation when contrasted with sham in both groups (p < 0.05). Conclusion: Obesity has a negative impact on symptoms and functional capacity. However, WB-EMS did not acutely enhance oxygen uptake or HRV during exercise in a population with obesity.

Factores sociodemográficos, clínicos y asistenciales asociados al impacto de la Covid-19 en la capacidad funcional respiratoria post alta hospitalaria / Sociodemographic, clinical and healthcare factors associated with the impact of Covid-19 on respiratory functional capacity after hospital discharge

La COVID-19 es una enfermedad infecciosa que causa importantes disfunciones respiratorias con repercusión a largo plazo, perdurando después del alta médico. En este estudio, se determinó la asociación entre los factores sociodemográficos, clínicos y asistenciales con el impacto de la COVID-19 en la capacidad funcional respiratoria post alta hospitalaria. Material y métodos: estudio observacional, analítico, transversal. La muestra conformada por 385 pacientes con diagnóstico de COVID-19. Se aplicó una ficha de recolección de datos, se estimó la capacidad funcional respiratoria. Se realizó un análisis bivariado mediante la prueba de chi cuadrado y razón de prevalencias considerando una significancia del 95% (p<0,05). Resultados: De los 385 pacientes, 228 (59,2%) se les percibió capacidad respiratoria normal y, disminuida en 157 (40,8%). Los adultos contemporáneos (55,84%) y masculinos (67,80%) fueron mayormente afectados. La comorbilidad (p= 0,292) y Co-Rads (p= 0,797) no mostraron estar directamente asociadas a la afectación respiratoria; contrario a RALE ≥ 3 en Radiografía de tórax (p=0,000). El tiempo en hospitalización, UCI y ventilación mecánica sugiere estar relacionado con la disminución respiratoria. Sin embargo, por RPc no hubo evidencia estadísticamente significativa. Pero, clínica severa 3.029 [1.611 ­ 5.696] p= 0.001 y RALE ≥3 4.079 [2.248 ­ 7.401] p= 0,000, arrojaron asociación. Conclusión: se identificaron como factores asociados el grado de severidad y RALE≥ 3 en radiografía de tórax. Se sugiere realizar estudios que confirme los hallazgos de esta investigación y se proponga un protocolo de rehabilitación integral dirigido a pacientes post covid-19 que les permita recuperar la normalidad en la capacidad funcional respiratoria(AU)

COVID-19 is an infectious disease that causes significant respiratory dysfunctions with long-term repercussions, lasting after medical discharge. In this study, association between socio-demographic, clinical and healthcare factors with the impact of COVID-19 on post-discharge respiratory functional capacity was determinated. Material and methods: observational study, analytical, cross-sectional study. The sample made up of 385 patients diagnosed with COVID-19. A data collection form was applied; the respiratory functional capacity was estimated. A bivariate analysis was performed using the fe chi square test and prevalence ratio, considering a significance of 95% (p<0.05). Results: of the 385 patients, 228 (59.2%) had normal respiratory capacity, and decreased in 157 (40.8%). Contemporary adults (55.84%) and males (67.80%) were mostly affected. Comorbidity (p= 0,292) and Co-Rads (p= 0,797) were not shown to be directly associated with respiratory involvement; contrary to RALE ≥ 3 in chest X-ray (p=0,000). The time in hospitalization, ICU and mechanical ventilation suggests to be related to the respiratory decrease. However, by PCR there was no statically significant evidence. But, clinical severe 3,029 [1,611 ­ 5,696] p= 0.001 and RALE ≥3 4,079 [2,248 ­ 7,401] p= 0,000, showed association. Conclusion: the degree of severity and RALE ≥ 3 in chest X-ray were identified as associated factors. It is suggest to carry out studies that confirm the findings of this research and propose a comprehensive rehabilitation protocol aimed at post-covid-19 patients that allows them to recover normal respiratory functional capacity(AU)

Effects of an intradialytic cardiovascular rehabilitation program on functional capacity and cardiac function: ICRP trial

Abstract Introduction: Chronic kidney disease (CKD) is a worldwide public health problem associated with an increased risk of death from cardiovascular complications. Although previous studies have described significant improvements in exercise in functional capacity and quality of life in patients with end-stage kidney disease (ESKD), there is a lack of studies that propose to assess its impact on cardiac function using transthoracic echocardiogram (ECHO). In addition, most of the intradialytic exercise protocols are inconsistent, and incomplete regarding their intensity prescription, time of intervention, and monitoring. Methods: The present study aims to evaluate the effects of an intradialytic cardiovascular rehabilitation protocol (ICRP) using medium intensity aerobic exercises, for 30 min. on cardiac function and functional capacity. In this 6-month longitudinal study, heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure, peripheral oxygen saturation (SpO2) and modified Borg scale will be analyzed in all HD sessions. The cardiac function will be evaluated by left ventricular ejection fraction (LVEF) through ECHO; functional capacity by the six-minute walk test (6MWT); quality of life through the SF-36 questionnaire and routine laboratory tests and KT/Vsp calculation before and after the ICRP. Conclusion: ICRP protocol will be examined and is expected to improve cardiac function, functional capacity, and quality of life in ESKD patients on hemodialysis.
