- ItemSomente MetadadadosAvaliação da capacidade funcional de exercício de pacientes com escoliose idiopática do adolescente no pós-operatório tardio(Universidade Federal de São Paulo (UNIFESP), 2015-09-10) Araujo, Geferson da Silva [UNIFESP]; Vidotto, Milena Carlos [UNIFESP]; http://lattes.cnpq.br/0334734747375995; http://lattes.cnpq.br/0206111611571178; Universidade Federal de São Paulo (UNIFESP)Patients with Adolescent Idiopathic Scoliosis (AIS) show reduced exercise functional capacity during the Incremental Shuttle Walk Test (ISWT), however, the effect of surgical procedure about this test isn?t known. Objective: To evaluate the Incremental Shuttle Walk Distance (ISWD) and physiological responses during ISWT in AIS patients in the late postoperative period. Simultaneously, we aimed to assess the respiratory muscle strength, lung function and to correlate the variables with Cobb angles. Methods: This study included twenty two adolescents with AIS in AIS Group (AG) and twenty one healthy subjects in Control Group (CG). In the first instance we evaluated: maximal inspiratory and expiratory pressures (MIP and MEP), forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). Two ISWT were performed, but only second ISWD was analised. During the second test was used a gas analyzer to assess: Peak oxigen uptake (VO2), carbon dioxide output (VCO2), tidal volume (VT), respiratory rate (RR), heart rate (HR) and relations. Results: Significantly lower values were observed in AG for variables: VO2 (22 ± 5 vs. 27 ± 4 ml/kg/min), ISWD (567 ± 94 vs.604 ± 86m), FVC (2,70 ± 0,47 vs. 3,33 ± 0,52L) e FEV1 (2,41 ± 0,46 vs. 2,84 ± 0,52 L). There were no differences for MIP and MEP. There were significant correlations between ISWD, VO2 (r = 0,70) and VO2/Kg (r = 0,80), moreover, there were correlations between VO2 and OUES (Oxigen Uptake Efficiency Slope) with breathing pattern (r = 0,51 e r = 0,65, respectively), but it was significantly lower in AG. Moderate correlations were observed between VO2 and OUES (r = 0,67), furthermore, there were moderate correlations between main thoracic curve with VO2 (r = -0,41) and VO2/Kg (r= -0,61). Conclusion: AIS patients in the late postoperative period have significantly reduced exercise functional capacity associated with reduced lung function, residual spinal curve and cardiovascular deconditioning.
- ItemAcesso aberto (Open Access)Capacidade inspiratória, limitação ao exercício, e preditores de gravidade e prognóstico, em doença pulmonar obstrutiva crônica(Sociedade Brasileira de Pneumologia e Tisiologia, 2007-08-01) Freitas, Clarice Guimarães de; Pereira, Carlos Alberto de Castro [UNIFESP]; Viegas, Carlos Alberto de Assis; Universidade de Brasília; Universidade Federal de São Paulo (UNIFESP); Universidade de Brasília Faculdade de MedicinaOBJECTIVE: To correlate the postbronchodilator (post-BD) inspiratory capacity (IC), % of predicted, with other markers of severity and prognostic factors in chronic obstructive pulmonary disease (COPD). METHODS: Eighty stable patients with COPD performed forced vital capacity and slow vital capacity maneuvers, as well as the 6-min walk test, prior to and after receiving albuterol spray (400 µg). Patients were divided into four groups, based on post-BD forced expiratory volume in one second. Several variables were tested to establish correlations with the post-BD distance walked, using univariate and multivariate analysis. Post-BD IC was found to correlated with Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging and with the Body mass index, airway Obstruction, Dyspnea, and Exercise capacity (BODE) index. RESULTS: Multivariate regression analysis revealed that the distance walked, % predicted, correlated significantly with the IC post-BD, % predicted (p = 0.001), long-term oxygen use (p = 0.014), and number of medications used in the treatment (p = 0.044). IC < 70% was observed in 56% patients in GOLD stages 3 or 4 vs. 20% in GOLD 1 or 2 (p < 0.001). IC < 70% was observed in (60%) patients with BODE score 3 or 4 vs. (33%) BODE score 1 or 2 (p = 0.02). CONCLUSION: Post-BD IC% predicted is the best functional predictor of distance walked and is significantly associated with GOLD staging and BODE index. Therefore, We propose that the inspiratory capacity should be added to the routine evaluation of the COPD patients.
- ItemAcesso aberto (Open Access)Valores de referência para espirometria em crianças pré-escolares(Sociedade Brasileira de Pediatria, 2013-08-01) Burity, Edjane Figueiredo; Pereira, Carlos Alberto de Castro [UNIFESP]; Rizzo, José Ângelo; Brito, Murilo C. A.; Sarinho, Emanuel Sávio Cavalcanti; Universidade Federal de Pernambuco; Universidade Federal de São Paulo (UNIFESP); UFPE Departamento de Medicina Clínica; Fundação Oswaldo Cruz Centro de Pesquisas Ageu MagalhãesOBJECTIVES: Reference values for lung function tests differ in samples from different countries, including values for preschoolers. The main objective of this study was to derive reference values in this population. METHODS: A prospective study was conducted through a questionnaire applied to 425 preschool children aged 3 to 6 years, from schools and day-care centers in a metropolitan city in Brazil. Children were selected by simple random sampling from the aforementioned schools. Peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory volumes (FEV1, FEV0.50), forced expiratory flow (FEF25-75) and FEV1/FVC, FEV0.5/FVC and FEF25-75/FVC ratios were evaluated. RESULTS: Of the 425 children enrolled, 321 (75.6%) underwent the tests. Of these, 135 (42.0%) showed acceptable results with full expiratory curves and thus were included in the regression analysis to define the reference values. Height and gender significantly influenced FVC values through linear and logarithmic regression analysis. In males, R2 increased with the logarithmic model for FVC and FEV1, but the linear model was retained for its simplicity. The lower limits were calculated by measuring the fifth percentile residues. CONCLUSION: Full expiratory curves are more difficult to obtain in preschoolers. In addition to height, gender also influences the measures of FVC and FEV1. Reference values were defined for spirometry in preschool children in this population, which are applicable to similar populations.
