Coffee consumption has no acute effects on glucose metabolism in healthy men : a randomized crossover clinical trial

We investigate the effect of coffee (caffeinated and decaffeinated) on glucose effectiveness and insulin sensitivity using the stable isotope minimal model protocol with oral glucose administration in healthy men

Validation of the WHOQOL-Bref instrument in Brazilian sign language (Libras)

Purpose: the recognition of the Brazilian Sign Language (Libras) as the official language of the Brazilian deaf, in 2002, reaffirms the linguistic and cultural particularities of the deaf population. Therefore, there is a lack of a validated instrument for assessing the Quality of Life of deaf people using Libras. With authorization from the World Health Organization (WHO), a version of the WHOQOL-Bref in Libras was developed, called WHOQOL-Bref/Libras. However, its psychometric properties have not been examined as yet. Therefore, the purpose of this work is to perform the psychometric validation of the WHOQOL-Bref/Libras. Methods: WHOQOL-Bref/Libras and a sociodemographic questionnaire were applied to 311 deaf people from the five Brazilian regions. To assess temporal stability, the questionnaire was readministered to 52 deaf people, over an interval of 2 weeks. Results: WHOQOL-Bref/Libras demonstrated satisfactory psychometric values for reliability, discriminant and construct validity, temporal stability, and internal consistency. Cronbach's alpha coefficient showed satisfactory values for each of the WHOQOL-Bref domains: Physical health (0.641), Psychological (0.705), Environment (0.710), and Overall-Bref domains (0.873). The WHOQOL-Bref/Libras is the appropriate option to assess the quality of life of deaf people who communicate through Libras. Conclusion: WHOQOL-Bref/Libras had a satisfactory psychometric performance; therefore, it is a valid option that will provide autonomous participation for the deaf in quality of life investigations

Pediatric emergency room: experience at a university hospital

OBJECTIVE: Describe the clinical course of pediatric patients treated at a pediatric emergency room in a university hospital. METHODS: This retrospective descriptive study was conducted between January 1st and December 31st, 2004. Data retrieved were: demographical and clinical characacteristics, diagnostic hypotheses, need of tracheal intubation, deaths, transfers and need of hospitalization of children between zero and 14 years old. Patients were divided in four groups: no deaths; deaths <24 hours; deaths >24 hours; transfers to other hospitals after initial care. RESULTS: 203 children were treated: 59.1% boys; mean age of 3.4 years; 65% previously healthy. The most common diagnosis was respiratory failure (31.1%). Of the 22 deaths, 3.5% took place during the first 24 hours and 7.4% after this; 172 children (84.7%) were discharged after a mean hospital length of stay of 19.2 days. Nine children (4.4%) were transferred to other hospitals. Among the 203 children, 50 children (24.6%) were intubated after admission and 86 children (42.4%) had to be admitted to a pediatric intensive care unit. CONCLUSIONS: The patients who died early were younger and mainly shock victims. Girls who suffered from previous diseases and respiratory failure were predominant among the patients who died 24 hours after initial care. Patients who survived the emergency crisis were mainly males, older and also presented respiratory diseases. The need for invasive procedures (tracheal intubation) and hospitalization in intensive care units was significant in this population, underscoring the need for adequate equipment and specialized professionals in the emergency pediatric hospital services.OBJETIVO: Descrever a casuística de pacientes pediátricos atendidos em sala de emergência pediátrica de um hospital universitário. MÉTODOS: Estudo retrospectivo descritivo de 1º de janeiro até 31 de dezembro de 2004, com crianças de zero a 14 anos, avaliadas quanto a dados epidemiológicos, hipótese diagnóstica, intubação orotraqueal, óbito, destino e duração da internação. Os pacientes foram divididos em quatro grupos: Não Óbitos; Óbitos <24 horas, Óbitos >24 horas e transferidos para outros hospitais. RESULTADOS: Foram atendidas 203 crianças; 59,1% meninos; média de idade 3,4 anos; 65% previamente hígidos. O diagnóstico mais freqüente foi insuficiência respiratória (31,1%). Dentre os 22 óbitos, 3,5% ocorreram nas primeiras 24 horas e 7,4% após estas primeiras 24 horas; 172 crianças (84,7%) evoluíram para alta após período médio de internação de 19,2 dias. Nove (4,4%) foram transferidas para outros hospitais. Das 203 crianças atendidas, 50 (24,6%) foram intubadas à admissão e 86 (42,4%) necessitaram internação em unidade de terapia intensiva pediátrica. CONCLUSÕES: Os pacientes que evoluíram para óbito precoce eram mais jovens e com diagnóstico de choque. Nos pacientes que evoluíram para óbito após 24 horas do atendimento inicial, predominaram meninas, com doenças prévias e insuficiência respiratória. Aqueles que sobreviveram ao atendimento de emergência eram, em maior freqüência, meninos mais velhos e com doenças respiratórias. Houve necessidade significativa de procedimento invasivo (intubação orotraqueal) e internação subseqüente em unidade de terapia intensiva, o que reforça a necessidade de equipamentos adequados e profissionais especializados no setor.15616
