This study aimed to provide a clinical decision rule for predicting pediatric OSA using commonly available clinical information. A prospective cohort study. Children between the ages of 3 to 6 years-old, referred for an otorhinolaryngology consultation due to clinical suspicion of OSA, were recruited from January to June 2014. At baseline age, weight, height, gender, body mass index, Pediatric Sleep Questionnaire (PSQ) scores, tonsil size, and oxygen desaturation index (ODI) were assessed. A logistic regression modeling was used with backward stepwise elimination to develop a prediction model. Sixty-seven children were included with a mean age of 4.51 years. Of the 67 children included in this study, 25 (37.3%) subjects were diagnosed with pediatric OSA. Significant predictors of pediatric OSA in the final model (odds ratio, 95% confidence interval) included PSQ score (5.12; 3.3-6.5), ODI (1.34; 1.0-1.79) and tonsil size (6.7; 3.22-9.75). The final decision rule had a sensitivity of 88% and a specificity of 86%. The area under the receiver operating characteristic curve was 0.897. The proposed clinical decision rule, based on three readily available variables, is a promising discriminating instrument for prediction of OSA among children between 3 and 6 years. IIb.

The Pediatric Sleep Questionnaire (PSQ) is a validated tool for sleep disordered breathing among children. Our aim was to cross-culturally translate and adapt the PSQ into Portuguese language for use in clinical and research settings. Methods: The PSQ was translated into Portuguese language in accordance with the stages recommended by International Guidelines and reviewed by a panel of experts. The caregivers of 180 children (aged from 4 to 12 years) answered the Portuguese version of PSQ. The reliability of the translated questionnaire was measured by Cronbach a, Pearson correlation and Kappa statistics. Results: Reliability analysis yielded an overall Cronbach a of 0.781, confirming the survey's consistency. The Cronbach a of the Portuguese PSQ domains ranged between 0.61 and 0.7. Test-retest reliability for all items was robust with correctness of >90.0% in all items, and the Kappa statistic ranged between 0.5 and 0.8. Conclusion: The Portuguese version of PSQ has sufficient reliability and validity to measure sleep disordered breathing outcomes, and showed to be linguistically accurate and acceptable for use by children in Portugal. ß

A total of 153 patients diagnosed with obstructive sleep apnea syndrome (OSAS) were assessed during a 6-months APAP treatment period. All patients underwent psychological evaluation prior to treatment (T1) and 1 to 3 months (T2) and 4 to 6 months (T3) post-APAP treatment. Of these, 107 patients maintained a stable adherence pattern to APAP during the treatment period. Forty-seven percent were poorly adherent, 27 % were moderately adherent and 26 % were optimally adherent OSAS patients. Several factors distinguished the three adherence patterns and some of these emerged as the main predictors. In T1, the first model included age, apnea-hypopnea index, outcome expectations and coping spiritual support, as main predictors to distinguish adherence patterns. In T2 and T3, two models emerged adjusted to the variables of model 1 that included leakage, self-efficacy, mobilizing family acquire/accept support and reframing in model 2 and self-efficacy in model 3. Generally, the areas under the ROC curve, presented a good discrimination. Findings revealed an integrative heuristic model that accounted for the joint influence of demographic, clinical, psychological, and family coping factors on poor, moderate, and optimal adherence patterns.

The aim of this study was to characterize and investigate the differences in terms of anxiety, depression, illness perception, and quality of life between female and male OSAS patients from a total of 111 patients (33 women and 78 men) who were recently diagnosed with OSAS in an outpatient clinic of a University Hospital in Portugal. They underwent a standardized protocol that included evaluation to assess of psychological morbidity (anxiety and depression -Hospital Anxiety and Depression Scale), illness representations (Brief Illness Perception Questionnaire), and quality of life (Sleep Apnea Quality of Life Index). The most significant differences between female and male OSAS patients result of apnea/hypopnea index (AHI), after controlling for body mass index (p 5 0.05); anxiety (p ¼ 0.000) and depression (p 5 0.005); consequences (p 5 0.005), identity (p ¼ 0.000), coherence (p 5 0.01), and emotional representation (p 5 0.005) of OSAS; and for daily functioning (p ¼ 0.000), emotional (p ¼ 0.001), and symptoms (p 5 0.05) domains of quality of life. Data suggest that women revealed more psychological morbidity associated with OSAS. Therefore, it seems extremely important to look at women as potential patients for sleep apnea and avoid looking up for a pattern of symptoms that rely on men as a norm to which women are compared.

Research paper thumbnail of Apnea/hypopnea index and benzodiazepine use in patients with arterial hypertension and excessive weight

It is unknown if the use of benzodiazepines, psychoactive drugs with a depressant effect on the brain, is similar, in this regard, to antidepressant drugs use. Thirty patients with treated arterial hypertension and excessive weight (body mass index >25), either regularly using (13 patients) or not using (17 patients) benzodiazepines, were studied, by comparing the apnea/hypopnea index measured in a sleep study in both groups. Cardiac left chamber dimensions, corrected QT interval, body weight, height and mass index, as well as cervical and abdominal circumferences, were additional parameters under study. The mean apnea/hypopnea index was found to be significantly greater in patients not under chronic benzodiazepine use, when compared to the other group of patients (21.8+/-12.4, n=17 versus 9.7+/-11.3, n=13, p<0.05). Mean cervical and abdominal diameters were also greater in patients not treated with benzodiazepines. We conclude that, in this small group of patients with treated arterial hypertension and excessive weight, chronic benzodiazepine therapy was not associated with a greater mean apnea/hypopnea index. Further studies are needed to establish if, in fact, an inverse association might exist.

O Scratch, software de construção de jogos e animações baseado na combinação de blocos, é um dos mais utilizados devido a sua facilidade de uso e sua interface convidativa. Visto que os jogos eletrônicos são lúdicos e fazem parte da cultura dos jovens, pensou-se na ideia de criar um projeto que tem como principal objetivo disseminar o ensino da computação e desmistificar a aprendizagem de linguagens de programação, mostrando aos alunos a possibilidade de desenvolvimento de jogos através da programação. Para isso, foi selecionado um grupo de alunos que apresentava bom desempenho na disciplina de matemática para participar das aulas em turno inverso, com a intenção de que tivessem um tempo dedicado apenas para as atividades. A experiência gerou resultados que demonstraram que alunos que tem facilidade em matemática aprendem com muito mais facilidade uma linguagem de programação. Também foi verificado através de um questionário de opinião criado no Google Docs que a maioria dos participantes assimilaram o conteúdo e demonstraram aumentar seu interesse pela área da informática.
