The results of the present study demonstrate that the PSQI-BR is a valid and reliable instrument for the assessment of sleep quality and equivalent to its original version when applied to individuals who speak the Brazilian Portuguese language. Despite relevant influences of language and cultural background, no major cultural adaptations were necessary during the validation process. The PSQI-BR can be a tool either for clinical management or research.

Objective: The aim of this study was to develop a Portuguese-language version of the Epworth sleepiness scale (ESS) for use in Brazil. Methods: The steps involved in creating the ESS in Brazilian Portuguese (ESS-BR) were as follows: translation; back-translation; comparison (by a committee) between the translation and the back-translation; and testing in bilingual individuals. The ESS-BR was applied to a group of patients who were submitted to overnight polysomnography in order to identify obstructive sleep apnea-hypopnea syndrome (OSAHS), insomnia and primary snoring. A control group was composed of subjects with a history of normal sleep habits, without reported snoring. Results: A total of 114 patients and 21 controls were included. The 8-item scores of the ESS-BR had an overall reliability coefficient of 0.83. The study group was composed of 59 patients with OSAHS, 34 patients with primary snoring and 21 patients with insomnia. One-way ANOVA demonstrated significant differences in ESS-BR scores among the four diagnostic groups (p < 0.001). Post-hoc tests between groups showed that the ESS-BR scores of the patients with insomnia did not differ from those of the controls (p > 0.05). The ESS-BR scores were significantly higher for OSAHS patients and for primary snorers than for controls (p < 0.05). In addition, the scores for OSAHS patients were significantly higher than were those for primary snorers (p < 0.05). Conclusions: The results of the present study demonstrate that the ESS-BR is a valid and reliable instrument for the assessment of daytime sleepiness, equivalent to its original version when applied to individuals who speak Brazilian Portuguese.Keywords: Validation studies; Sleep disorders; Cross-cultural comparison; Disorders of excessive somnolence. ResumoObjetivo: Desenvolver uma versão da escala de sonolência de Epworth (ESE) para o português para uso no Brasil. Métodos: A versão no português do Brasil (ESE-BR) foi desenvolvida de acordo com as seguintes etapas: tradução; retrotradução; comparação entre a tradução e a retrotradução (por um comitê); e aplicação em indivíduos bilín-gues. A ESE-BR foi aplicada a um grupo de pacientes submetidos à polissonografia de noite inteira para identificar síndrome da apneia-hipopneia obstrutiva do sono (SAHOS), insônia e ronco primário. Um grupo controle foi composto de indivíduos com história de hábitos normais de sono, sem ronco aparente. Resultados: Um total de 114 pacientes e 21 controles foram incluídos. Os 8 itens do ESE-BR tiveram um coeficiente de confiabilidade total de 0,83. O grupo em estudo foi composto por 59 pacientes com SAHOS, 34 pacientes com ronco primário e 21 pacientes com insônia. One-way ANOVA demonstrou diferenças significativas nos escores do ESE-BR entre os quatro grupos diagnósticos (p < 0,001). Testes post hoc entre grupos pareados mostraram que os escores do ESE-BR para insones não diferiram daqueles dos controles (p > 0,05). Os escores dos pacientes com SAHOS e nos roncadores primários foram significativamente maiores que os...

CF patients had a worse subjective sleep quality and small changes in sleep architecture. In nonhypoxic, adult CF patients, sleep desaturation is common, is not associated with obstructive sleep events, and can be accurately predicted by awake resting SpO(2) <94%.

ResumoObjetivo: Avaliar a capacidade funcional no exercício em crianças e adolescentes com bronquiolite obliterante pós-infecciosa. Conclusion:The majority of these post-infectious bronchiolitis obliterans patients exhibited reduced functional capacity, exhibited during both CPET and the 6MWT. Due to its greater feasibility, 6MWT could be an alternative where CPET is not available.J Pediatr (Rio J). 2008;84(4):337-343

The study demonstrated that a home exercise programme had positive effects in adult patients with CF, including gain in muscle strength in UULL. No increase in tolerance to exercise was shown and improvement in the quality of life of the patients who received intervention.
