RESUMO
Patients with CHD are less active if compared with controls and have limited functional capacity, related to muscle weakness and fatigue. The aim of this study was to evaluate the peripheral and respiratory muscle strength of children and adolescents with CHD with systematic review and meta-analysis. The review included observational and randomised control trial studies which evaluated peripheral and respiratory muscle strength in children and adolescents with CHD under 18 years old. The peripheral muscle strength was evaluated through dynamometry and respiratory muscle strength through manovacuometry. In studies that compared patients with CHD and respective control groups, it was possible to perform a meta-analysis. A total of 5634 articles met the criteria of eligibility, 15 were included in the systematic review, and 4 were included in the meta-analysis. Twelve studies assessed peripheral muscle strength with a reduction in patients with CHD. In the meta-analysis, patients with CHD had lower muscle strength than controls (-34.07 nm; 95% CI, -67.46 to -0.68; I2 47%; p for heterogeneity = 0.05), and the meta-analysis of the handgrip muscle strength showed no significant difference between patients with CHD and controls (0.08 nm; 95% CI, -6.39 to 6.55; I2 98%; p for heterogeneity <0.00001). The meta-analysis in the present study showed lower limb muscle strength in patients with CHD in comparison to controls. In contrast, no difference was found regarding hand grip strength. Also, the review showed lower respiratory muscle strength in patients with CHD, yet no meta-analysis was possible to perform.

OBJECTIVE: To describe the profile and the scientific output of physical therapists researchers holding a research productivity fellowship (PQ) from the Brazilian National Council of Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico-CNPq). METHOD: This is a cross-sectional study, which has evaluated the Lattes Curriculum of all PQ physiotherapy researchers registered at CNPq holding a research productivity fellowship in the period of 2010. The variables analyzed were: gender, geographic and institutional distribution, duration since doctorate defense, research productivity fellowship level, scientific output until 2010 and the H index in Scopus(®) and ISI databases. RESULTS: A total of 55 PQ from the CNPq were identified in the area of knowledge of Physical Therapy and Occupational Therapy, being 81.8% from the Southeast region of Brazil. They were predominantly female (61.8%), with research productivity fellowship level PQ2 (74.5%), and with average time since doctorate defense of 10.1 (±4.1) years. A total of 2.381 articles were published, with average of 42.5 (±18.9) articles/researcher. The average of articles published after doctorate defense was 39.40 (±18.9) articles/researchers with a mean output of 4.2 (±2.0) articles/year. We found 304 articles indexed in the Scopus(®) database with 2.463 citations, and 222 articles indexed in the Web of Science with 1.805 citations. The articles were published in 481 journals, being 244 (50.7%) of them listed on JCR-web. The researchers presented a median 5 of the H index in the Scopus(®) database, and a median 3 in ISI. CONCLUSION: The scientific output of the researchers with research productivity fellowship in the field of physical therapy stands out in their indicators, since the figures are very promising for a relatively young area and as it can be observed by the amount of published articles and citations obtained by the national and international research community.

RESUMO OBJETIVO: Descrever o perfil e a produção científica de fisioterapeutas pesquisadores com bolsa produtividade (PQ) do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). MÉTODO: Estudo transversal descritivo. Foi realizada a avaliação, por meio dos currículos Lattes, dos pesquisadores fisioterapeutas PQ do CNPq com vigência em 2010. As variáveis do estudo foram: gênero, distribuição geográfica e institucional, tempo de doutoramento, categoria da bolsa, produção científica até 2010 e índice H na base de dados do Scopus e ISI. RESULTADOS: Foram identificados 55 PQ do CNPq na área de conhecimento de Fisioterapia e Terapia Ocupacional, sendo 81,8% da região sudeste, com predominância do gênero feminino (61,8%), bolsas categoria PQ2 (74,5%) e com tempo médio de doutorado de 10,1 (±4,1) anos.

BACKGROUND: The epidemiology of asthma has been investigated with questionnaires, such as the International Study of Asthma and Allergies in Childhood protocol. AIM: To investigate the performance of the questions of the International Study of Asthma and Allergies in Childhood questionnaire to diagnose asthma in adolescents. METHODS: This is a population-based cross-sectional study of adolescents in the Syndrome of Obesity and Risk Factors for Cardiovascular Disease study. The validity of the asthma symptoms of the International Study of Asthma and Allergies in Childhood protocol was assessed by calculating sensitivity, specificity, positive and negative posttest probabilities, and Youden's Index, taking as a gold standard the history of a medical diagnosis of asthma. Risk ratios (RRs) and 95% confidence intervals (CIs), adjusting for sex and age, were calculated using Cox regression model. RESULTS: In total, 575 adolescents were investigated. Overall, 28.7% reported a lifetime medical diagnosis of asthma, and 40.0% reported at least one episode of wheezing. Ever wheezing had the highest sensitivity (80.6%) for the diagnosis of asthma, compared with the other ISAAC questions. Adolescents who reported ever wheezing were about 8 times more likely (adjusted RR: 8.3; 95% CI: 4.9-14.2) to have ever had asthma, independent of age and sex. Symptoms within the last 12 months (wheezing, cough without cold or respiratory infection, sleep disturbed due to wheezing, wheezing due to exercise, speech limited due to wheezing) had specificity of 92.0% or higher. Dry cough at night without cold or respiratory infection was the strongest independent predictor of asthma (adjusted RR: 8.8; 95% CI: 6.1-12.7). CONCLUSIONS: Ever wheezing is the most sensitive indicator of the diagnosis of asthma but falsely identifies a portion of adolescents as asthmatic. Symptoms of asthma in the last 12 months, such as cough without cold or respiratory infection, are rarely positive in the absence of a lifetime asthma diagnosis. The combination of ever wheezing for screening and the presence of other symptoms within the past 12 months to confirm the diagnosis could be an effective strategy to identify the prevalence of asthma in communities.

BACKGROUND: Malnutrition might be expected to result in reduced maximum respiratory pressure and pulmonary function in cystic fibrosis (CF). OBJECTIVE: To assess the relationship between nutritional status and maximum respiratory pressures in patients with CF. METHODS: We performed a prospective cross-sectional study of patients > or = 16 y old attending the Adult CF Program at Hospital de Clínicas de Porto Alegre, Porto Alegre, Brazil. Maximum inspiratory and expiratory pressures (MIP and MEP) were measured as indexes of respiratory muscle strength. Nutritional status was assessed via body mass index (BMI), triceps-skin-fold thickness and mid-upper-arm-muscle circumference. The patients were classified into 2 groups according to BMI: normal and nutritional depletion. Spirometry was performed by all subjects. RESULTS: The study included 39 patients (23 female/16 male) with a mean age of 23.7 +/- 6.4 y. The mean +/- SD percent-of-predicted MIP was 88.0 +/- 28.5% in the normal group and 83.2 +/- 27.3% in the nutritional-depletion group (p = 0.605). The mean +/- SD percent-of-predicted MEP was 84.7 +/- 24.2% in the normal group and 86.1 +/- 26.3% in the nutritional-depletion group (p = 0.874). The mean +/- SD percent-of-predicted forced expiratory volume in the first second (FEV(1)) was 55.2 +/- 27.5% in the normal group and 50.0 +/- 25.6% in the nutritional-depletion group (p = 0.568). MEP and MIP had no significant correlation to BMI or FEV(1). CONCLUSION: MEP and MIP had no significant relationship to nutritional status, clinical score, chest radiograph score, and pulmonary function.
