Effectiveness of Cardiac Rehabilitation With mHealth Through Smartphone Functionalities: A Systematic Review Protocol.

Cardiovascular diseases are the leading cause of mortality worldwide, requiring support to manage symptoms and improve prognosis. Home-based cardiac rehabilitation is a realistic resource for this purpose, but it requires patients' self-management skills in order to change behaviours. Smartphones are considered mHealth technology (mobile technological resources in healthcare) and have the potential to provide modalities for delivery of cardiac rehabilitation. This systematic review aims to examine these modalities and identify those that are most effective for improving exercise capacity, quality of life, and patient compliance. Randomized controlled trials (1994 to 2022) performed with adults with coronary artery disease (post-myocardial infarction, angina, post-coronary artery bypass graft surgery) or heart failure eligible for home-based cardiac rehabilitation (mHealth) will be selected. Studies published in English, Spanish, or Portuguese that compare rehabilitation-specific mobile apps or smartphone-based features with conventional cardiac rehabilitation will be included. Searches will be conducted in MEDLINE, CENTRAL, EMBASE, LILACS, PEDro, grey literature, and ongoing or recently completed studies. Data and risk of bias will be assessed, and if appropriate, a meta-analysis will be carried out.

Les maladies cardiovasculaires constituent la principale cause de décès dans le monde et nécessitent des soins de soutien pour la prise en charge des symptômes et l'amélioration du pronostic. La réadaptation cardiaque à domicile est un moyen réaliste d'y arriver, mais pour ce faire, les patients doivent acquérir des compétences en autogestion qui leur permettront de modifier leurs comportements. Les téléphones intelligents sont considérés comme une technologie de santé mobile qui a le potentiel d'améliorer les méthodes d'administration de la réadaptation cardiaque. La présente revue systématique vise à examiner ces modalités et à cibler les plus efficaces dans l'amélioration de la capacité physique, de la qualité de vie et de l'adhésion des patients au programme. Des essais contrôlés randomisés (1994 à 2022) réalisés auprès d'adultes qui sont atteints d'une maladie coronarienne (angine ou trouble ayant mené à un infarctus du myocarde ou à un pontage aortocoronarien) ou d'insuffisance cardiaque et qui sont admissibles à la réadaptation cardiaque à domicile (technologie de santé mobile) seront sélectionnés. Nous inclurons les études publiées en anglais, en espagnol ou en portugais qui comparent des applications mobiles de réadaptation ou des fonctionnalités de téléphones intelligents à un programme traditionnel de réadaptation cardiaque. Les bases de données MEDLINE, CENTRAL, EMBASE, LILAC et PEDro, seront interrogées et la littérature grise ainsi que les études en cours seront examinées. Les données et le risque de biais seront évalués, et s'il y a lieu, une métanalyse sera effectuée.

Contributions of musculoskeletal rehabilitation in patients after chikungunya fever: a systematic review.

INTRODUCTION: Chikungunya fever is an infection transmitted by the Chikungunya virus (CHIKV), which is an arbovirus that is transmitted by the mosquitoes Aedes aegypti and Aedes albopictus. The most common sequelae caused by CHIKV are chronic musculoskeletal pain, nerve damage, joint deformation and functional impairment. OBJECTIVE: To systematically identify the literature on the contributions of physiotherapy in the treatment of patients with CHIKV sequelae. MATERIALS AND METHODS: Systematic review of the literature, guided by the recommendations of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). The databases used were PUBMED, LILACS, Scielo and PEDro. Experimental studies and/or full case studies published without language restriction or publication data were included, in which they stood out as contributions of musculoskeletal functional rehabilitation in the treatment of patients with the condition in question. Analytical observational studies, editorial letters, review protocols, reflective studies, literature reviews and articles that do not have an abstract and/or full text available online were excluded. RESULTS: The search in the databases was carried out between July and August 2022. A total of 4,782 articles were found on the platforms used and 10 articles from the gray literature search. After the duplicate analysis, 2,027 studies were excluded, leaving 2,755 articles that had their titles and abstracts read, of which 600 articles were selected for full reading. After this step, a final sample of 13 articles was eligible for this review. FINAL CONSIDERATIONS: The most consolidated approaches used in the literature demonstrate that kinesiotherapy, associated or not with electrothermophototherapy, the pilates method and auriculotherapy are useful resources in the treatment of these individuals, significantly inspired by pain relief, improved quality of life and of functionality.

Normative values and reference equation for the six-minute step test to evaluate functional exercise capacity: a multicenter study / Valores normativos e equação de referência para o teste do degrau de seis minutos para avaliar a capacidade funcional de exercício: um estudo multicêntrico

ABSTRACT Objective: To establish normative values and a reference equation for the number of steps climbed during the six-minute step test (6MST) in healthy adults, and to assess the reliability of the test and of the equation. Methods: This was a multicenter cross-sectional study involving 468 healthy volunteers (age range: 18-79 years) recruited from the general community in six research laboratories across different regions of Brazil, which is a country with continental dimensions. The 6MST was performed twice (30-min interval), and clinical, demographic, and functional variables were evaluated. An independent sample of 24 volunteers was evaluated to test the reference equation a posteriori. Results: The number of steps had excellent test-retest reliability (intraclass correlation coefficient = 0.96 [95%CI: 0.95-0.97]), and the mean number of steps was 175 ± 45, the number being 14% greater in males than in females. The best performance on the test was correlated with age (r = −0.60), sex (r = 0.28), weight (r = 0.13), height (r = 0.41), BMI (r = −0.22), waist circumference (r = −0.22), thigh circumference (r = 0.15), FVC (r = 0.54), and physical activity level (r = 0.17; p < 0.05 for all). In the regression analysis, age, sex, height, and weight explained 42% of the variability of the 6MST. Normative values were established for the 6MST according to age and sex. There was no difference between the 6MST values from the independent sample and its predicted values (157 ± 29 steps vs. 161 ± 25 steps; p = 0.47; 97% of predicted values). Conclusions: The normative values and the reference equation for the 6MST in this study seem adequate to accurately predict the physical functional performance in adults in Brazil.

RESUMO Objetivo: Estabelecer valores normativos e uma equação de referência para o número de degraus subidos no teste do degrau de seis minutos (TD6) em adultos saudáveis, bem como avaliar a confiabilidade do teste e da equação. Métodos: Estudo transversal multicêntrico com 468 voluntários saudáveis (faixa etária: 18-79 anos) recrutados na comunidade geral em seis laboratórios de pesquisa em diferentes regiões do Brasil, um país de dimensões continentais. O TD6 foi realizado duas vezes (com 30 min de intervalo entre uma e outra), e foram avaliadas variáveis clínicas, demográficas e funcionais. Uma amostra independente composta por 24 voluntários foi avaliada para testar a equação de referência a posteriori. Resultados: O número de degraus subidos apresentou excelente confiabilidade teste-reteste [coeficiente de correlação intraclasse = 0,96 (IC95%: 0,95-0,97)], e a média de degraus subidos foi de 175 ± 45, sendo 14% maior no sexo masculino. O melhor desempenho no teste correlacionou-se com as seguintes variáveis: idade (r = −0,60), sexo (r = 0,28), peso (r = 0,13), estatura (r = 0,41), IMC (r = −0,22), circunferência da cintura (r = −0,22), circunferência da coxa (r = 0,15), CVF (r = 0,54) e nível de atividade física (r = 0,17; p < 0,05 para todos). Na análise de regressão, idade, sexo, estatura e peso explicaram 42% da variabilidade do TD6. Foram estabelecidos valores normativos para o TD6 de acordo com a idade e o sexo. Não houve diferença entre os valores do TD6 na amostra independente e os valores previstos (157 ± 29 vs. 161 ± 25 degraus subidos; p = 0,47; 97% dos valores previstos). Conclusões: Os valores normativos e a equação de referência para o TD6 neste estudo parecem adequados para predizer com precisão o desempenho físico funcional em adultos no Brasil.

Maximum inspiratory pressure and rapid shallow breathing index as predictors of successful ventilator weaning.

[Purpose] To investigate the predictive value of maximum inspiratory pressure (MIP) and the rapid shallow breathing index (RSBI) in a ventilator weaning protocol and to evaluate the differences between clinical and surgical patients in the intensive care unit. [Subjects and Methods] Patients aged ≥15 years who underwent orotracheal intubation for mechanical ventilation and who met the criteria of the weaning protocol were included in the study. Receiver operating characteristic (ROC) curves were calculated for the analysis of each index. [Results] Logistic regression analysis was also performed. MIP showed greater sensitivity and specificity [area under the curve (AUC): 0.95 vs. 0.89] and likelihood ratios (LR) (positive(+): 20.85 vs. 9.45; negative(-): 0.07 vs. 0.17) than RSBI in the overall sample (OS) as well as in clinical patients (CP) (AUC: 0.99 vs. 0.90; LR+: 24.66 vs. 7.22; LR-: 0.01 vs. 0.15) and surgical patients (SP) (AUC: 0.99 vs. 0.87; LR+: 9.33 vs. 5.86; LR-: 0.07 vs. 0.14). The logistic regression analysis revealed that both parameters were significantly associated with the weaning success. The MIP showed greater accuracy than the RSBI (OS: 0.93 vs. 0.85; CP: 0.98 vs. 0.87; SP: 0.93 vs. 0.87). [Conclusion] Both parameters are good predictors of successful ventilator weaning.

Cardiac, ventilatory, and metabolic adjustments in chronic obstructive pulmonary disease patients during the performance of Glittre activities of daily living test.

Functional status and quality of life are measures of the chronic obstructive pulmonary disease (COPD) patient's health status and can demonstrate the impact of the disease on the patient's ability to perform activities of daily living (ADLs). The Glittre-ADL test was developed to evaluate the functional status of COPD patients and their ability to perform activities of daily life. The objective of this study was to evaluate the cardiac, respiratory, and metabolic adjustments and reproducibility of the Glittre ADL test performed by COPD patients. Twenty-two mild to severe COPD patients (forced expiratory volume in 1 second (FEV1): 56.6 ± 19.9% predicted; mean age: 66.3 ± 9.18 years old) were enrolled in this study. Metabolic (oxygen uptake (VO2), carbon dioxide production (VCO2), pulmonary ventilation (VE)/VCO2, and VE/VO2), ventilatory (tidal volume, respiratory rate, and VE), and cardiovascular (pulse oxygen saturation, VO2/heart rate (HR), and HR) variables, lower limbs fatigue, and dyspnea (Borg score) after each lap of two Glittre ADL test were analyzed. All metabolic, ventilatory, and cardiac variables increased their values up to the third lap and remained stable (plateau) until the end of the test (five laps; multivariate analysis); there was no difference among the time spent to complete each of the five laps in each test and between tests (total time of second test: 4 minutes and 3 seconds); the second test was 17.8 seconds (6.6%) shorter than the first one (NS). All variables were highly reproducible in the two tests (NS). At the end of the test, patients reached 87.7% of the VO2 max, 81% of VE peak, and 88.5% of the HR peak obtained from an incremental maximal test on a treadmill. The Glittre ADL test is easy for COPD patients to perform and is a highly reproducible test in COPD patients with mild to severe stages of the disease. In addition, our results suggest that it is possible to demonstrate the patient's functional capacity with a single test of only three laps, making it faster and easier to apply and less stressful for some patients.
