ABSTRACT
PURPOSE: To analyse the psychometric properties of the translated and cross-culturally adapted version of the OSAKA (Obstructive Sleep Apnea Knowledge and Attitudes) questionnaire in the Brazilian Portuguese language. METHODS: The OSAKA instrument was translated by two independent translators, and the back-translated conciliated version was presented and approved by Washington University, which holds the intellectual property for the OSAKA questionnaire. Physicians from different specialties electronically completed the OSAKA instrument and the ASKME (Assessment of Sleep Knowledge in Medical Education) questionnaire, which was used as an auxiliary instrument to analyse the construct validity. RESULTS: The questionnaire was tested with 176 physicians. The items from the knowledge and attitudes domains presented acceptable internal consistency values, with McDonald's omega coefficients (Ω) of 0.70 and 0.73, respectively. The OSAKA questionnaire showed a moderate correlation with the ASKME instrument (r = 0.60, p < 0.001) and excellent retest reliability, with an intraclass correlation coefficient of 0.81. There were differences in knowledge between the medical specialties (p < 0.001). Regarding attitudes, most respondents considered obstructive sleep apnoea and its diagnosis to be important and felt confident in identifying it, but the same majority did not feel confident in treating the disease. CONCLUSION: The OSAKA instrument, as a translated and cross-culturally adapted Brazilian Portuguese version, presented psychometric properties with adequate reliability and validity.

PURPOSE: Obstructive Sleep Apnea (OSA) is related to cardiovascular, metabolic, and neurocognitive diseases. Furthermore, OSA symptoms, such as excessive sleepiness, fatigue, and mood disorders, may interfere in functioning. The assessment of this aspect in patients with OSA is not frequent and no specific instrument is available in the literature. Our aim is to identify if the International Classification of Functioning, Disability and Health (ICF) domains are considered in the validated instruments used to assess patients with OSA. METHODS: In this integrative literature review, three databases were searched: Pubmed, Embase, and LILACS. Bibliographic survey was carried out in 2020, between March and July. Articles published in English, Portuguese, and Spanish with validated tools to assess OSA in adults were included. RESULTS: Thirty instruments have undergone a process of concept extraction and coding according to the ICF, generating a total of 769 significant concepts. It was observed that the function domain was the most prevalent, making 42% (n = 323) of the concepts, followed by domains of activity (16%), participation (10%), environmental factors (5%), personal factor (5%), and structure (1%). Only one instrument, the "Sleep Apnea Quality of Life Index (SAQLI)," encompasses all domains of the ICF in its constructs. CONCLUSION: In the analyzed instruments, the function domain prevails, with most concepts related to sleep functions. Only one validated instrument included in this research covered all the ICF domains. This instrument closely matched the recommended way of assessing functioning, though it approached the domains in an unbalanced way.

A oxigenoterapia é uma terapêutica eficaz na Insuficiência Respiratória Aguda. Porém, apesar de ser essencial a vida, o oxigênio, como qualquer medicamento, quando administrado de forma indevida, pode ser tóxico e ter sérias consequências. O presente estudo tem a finalidade de realizar uma revisão sistemática sobre o uso da oxigenoterapia em pacientes agudos. Estudo seccional e documental realizado por meio de revisão sistemática da literatura disponível na Biblioteca Virtual de Saúde (Bireme). Os critérios de inclusão foram: estudos que tratassem sobre oxigenoterapia e sua utilização a nível hospitalar em pacientes agudos sendo esses temas abordados em conjunto, artigos publicados em português, inglês ou espanhol, textos completos disponíveis online e datados entre 2004 e 2014. Os critérios de exclusão foram: artigos repetidos, incompletos e que não abordassem o assunto. Através desta revisão as evidências mostraram que a oxigenoterapia foi benéfica na redução da disfunção respiratória e no risco de morte súbita na epilepsia e em pacientes com diagnóstico clínico de acidente vascular cerebral agudo, favorecendo uma melhora na recuperação neurológica. Porém, são necessários maiores estudos sobre esta terapia em pacientes agudos. Foram evidenciados alguns benefícios terapêuticos, contudo, deve-se destacar a importância do conhecimento por parte dos profissionais com o intuito de reduzir o uso indiscriminado e prevenir os efeitos deletérios do oxigênio.

Oxygen therapy is an effective therapy in acute respiratory failure. However, despite being essential to life, oxygen, like any drug, when administered improperly, can be toxic and have serious consequences. This study is a review on the use of oxygen therapy in acute patients. Cross-sectional and documentary study conducted through a systematic review of the available literature on the Virtual Health Library (Bireme). Inclusion criteria were studies that addressed on oxygen therapy and its use in hospital in acute patients, articles published in Portuguese, English or Spanish, available online full-text and dated between 2004 and 2014. The criteria for exclusion were repeated articles or incomplete. Through this review the evidence showed that oxygen therapy was beneficial in reducing respiratory dysfunction and the risk of sudden death in epilepsy and in patients with a clinical diagnosis of acute stroke, favoring an improvement in neurological recovery. But we need more studies on this therapy in acute patients. Some benefits of this therapy are observed, however, we highlighted the importance of knowledge by professionals in order to reduce the indiscriminate use and prevent the deleterious effects of oxygen.
