- ItemAcesso aberto (Open Access)Avaliação da capacidade de exercício em portadores de doença pulmonar obstrutiva crônica: comparação do teste de caminhada com carga progressiva com o teste de caminhada com acompanhamento(Sociedade Brasileira de Pneumologia e Tisiologia, 2006-04-01) Rosa, Fernanda Warken [UNIFESP]; Camelier, Aquiles Assunção [UNIFESP]; Mayer, Anamaria [UNIFESP]; Jardim, José Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: To evaluate the applicability of the incremental (shuttle) walk test in patients with chronic obstructive pulmonary disease and compare the performance of those patients on the shuttle walk test to that of the same patients on the encouraged 6-minute walk test. METHODS: A cross-sectional study was conducted, in which 24 patients with chronic obstructive pulmonary disease were selected. In random order, patients were, after an initial practice period, submitted to a shuttle walk test and an encouraged 6-minute walk test. RESULTS: The patients obtained a higher heart rate (expressed as a percentage of that predicted based on gender and age) on the encouraged 6-minute walk test (84.1 ± 11.4%) than on the shuttle walk test (76.4 ± 9.7%) (p = 0.003). The post-test sensation of dyspnea (Borg scale) was also higher on the encouraged 6-minute walk test. On average, the patients walked 307.0 ± 89.3 meters on the shuttle walk test and 515.5 ± 102.3 meters on the encouraged 6-minute walk test (p < 0.001). There was a good correlation between the two tests in terms of the distance walked (r = 0.80, p < 0.001). CONCLUSION: The shuttle walk test is simple and easy to implement in patients with chronic obstructive pulmonary disease. The encouraged 6-minute walk test produced higher post-test heart rate and greater post-test sensation of dyspnea than did the shuttle walk test.
- ItemAcesso aberto (Open Access)Avaliação da qualidade de vida pelo Questionário do Hospital Saint George na Doença Respiratória em portadores de doença pulmonar obstrutiva crônica: validação de uma nova versão para o Brasil(Sociedade Brasileira de Pneumologia e Tisiologia, 2006-04-01) Camelier, Aquiles Assunção [UNIFESP]; Rosa, Fernanda Warken [UNIFESP]; Salmi, Christine [UNIFESP]; Nascimento, Oliver Augusto [UNIFESP]; Cardoso, Fábio [UNIFESP]; Jardim, José Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: The objective of this study was to evaluate the applicability of a modified version of the Saint George's Respiratory Questionnaire. The version evaluated elicits agree and do not agree, rather than yes and no, responses. The intention is to facilitate the comprehension of double-negative questions and to promote better recollection of symptoms by patients by shortening their symptom histories from 12 months to 3 months. METHODS: A total of 30 clinically stable patients with chronic obstructive pulmonary disease were evaluated. The Saint George's Respiratory Questionnaire and the modified version of the same were administered 15 days apart. RESULTS: All of the patients presented health-related alterations in their quality of life. Comparing mean scores between the two questionnaires, the greatest difference was seen in the Symptoms domain. No significant differences were found in any of the remaining domains or in the total scores. In a subsequent analysis, significant correlations between the two questionnaires were found in all domains: Symptoms (r = 0.71; p < 0.001); Activity (r = 0.75; p < 0.001); Impact (r = 0.73; p < 0.001) and Total (r = 0.86; p < 0.001). CONCLUSION: The modified version of the Saint George's Respiratory Questionnaire is as effective as the original in gauging quality of life. However, various symptoms recollection time frames should be investigated in order to determine which would be the best time frame to employ in the analysis.
- ItemAcesso aberto (Open Access)Biometrias óptica e ultra-sônica: comparação dos métodos usados para o cálculo da lente intra-ocular acomodativa(Conselho Brasileiro de Oftalmologia, 2004-12-01) Oliveira, Filipe de [UNIFESP]; Muccioli, Cristina [UNIFESP]; Lopes, Yara Cristina [UNIFESP]; Soriano, Eduardo Sone [UNIFESP]; Belfort, Rubens Junior [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To compare reproducibility, level of agreement and correlation of two ultrasonic biometers and one optical biometer for the calculation of accommodative intraocular lens. METHODS: Cataract patients were submitted to the examination with 3 different biometers (IOLMaster, Axis II and Humphrey Mod. 820) before the implant of the C&C Vision AT-45 accommodative silicone intraocular lens. The Axis II biometer was used for both contact and immersion biometry. Axial length, anterior chamber depth and keratometry were the analyzed biometric parameters. RESULTS: Thirty-four patients from 53 to 90 years old (mean 70.6 y) were submitted to the examination with the three different biometers. The lowest mean axial length (23.12 mm) was obtained with the Axis II/contact and the highest (23.21 mm) with the Humphrey biometer. The lowest mean anterior chamber depth (2.97mm) was obtained with the Humphrey and the highest (3.10mm) with the IOLMaster. Reproducibility for axial length was high for all the biometers tested (coefficient of variation: 3.02% for Humphrey and Axis II / immersion; 3.07 % for Axis II/contact and 3.19% for IOLMaster). All biometers presented nearly equal results of the analyzed parameters (99.01% for axial length and 94.77% for anterior chamber depth). Pearson's coefficient showed a high correlation between the biometers, regarding the axial length and anterior chamber depth measurements. CONCLUSION: The devices used in this study showed excellent reproducibility and high level of agreement and of the axial length, anterior chamber depth and keratometry measurements, making it possible to reduce errors of intraocular lens calculation and visual insatisfaction after cataract surgery.
- ItemAcesso aberto (Open Access)Reprodutibilidade de informações em estudo de fatores de risco para o diabetes mellitus insulino-dependente(Faculdade de Saúde Pública da Universidade de São Paulo, 1997-10-01) Gimeno, Suely Godoy Agostinho [UNIFESP]; Souza, José Maria Pacheco De; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)The reliability of information about mothers' and fathers' education, weight and height at birth, history of diarrhoea, duration of exclusive breast feeding and age of introduction of cows' milk products, selected from a structured questionnaire used in home interviewers was examined in a sample of 38 cases and 38 controls from a study related to the risk factors of insulin-dependent diabetes mellitus. The repetition of the questions was done by telephone. The agreement between the answers of both interviewers was verified using the kappa statistic (categorical variables) and the intra-class correlation coefficient (quantitative variables). The results enable one to conclude that the information is reproducible.
- ItemAcesso aberto (Open Access)Translation, adaptation and reliability study of the Scale to Assess Unawareness of Mental Disorder - SUMD(Associação Brasileira de Psiquiatria - ABP, 2005-06-01) Fiss, Nina [UNIFESP]; Chaves, Ana Cristina [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)INTRODUCTION: Previous studies have suggested that lack of insight into mental disorder can be an important predicting factor involving the course of psychotic disorders mainly regarding compliance with treatment. The Scale to Assess Unawareness of Mental Disorder-SUMD is a semi-structured open interview that evaluates global insight, insight into illness and insight into symptoms. The SUMD has shown good reliability and validity and has demonstrated certain advantages over previous measures of insight, suggesting the usefulness of a multidimensional view of this complex concept. OBJECTIVE: The aim of this study is to translate, adapt and test the reliability of the SUMD in schizophrenic patients. METHODS: This study involved 35 schizophrenic patients according to the DSM-IV criteria, who where under treatment in the Schizophrenia Program of the Federal University of São Paulo. Two independent examiners conducted the reliability study simultaneously. RESULTS: The results demonstrated that the SUMD achieved a good intraclass reliability coefficients between investigators - ICC ranged from 0.55 to 0.97 - for the general items to assess awareness of mental disorder and 0.56 to 0.98 - for the symptoms items. DISCUSSION: These coefficients were similar to those found by the researchers who developed this scale. The SUMD scale has proven to be easily applied and may be deemed an useful instrument with good psychometrics capacities in researches involving schizophrenic subjects.
