ABSTRACT

Distúrbios do sono e as alterações do estado de humor, quando não tratados, estão associados à perda de produtividade e acidentes de trabalho, resultando em lesões e fatalidade. Esses distúrbios são subdiagnosticados e subtratados em contextos clínicos, porque podem ser assintomáticos e o exame de polissonografia tem custo elevado. Por isso, questionários são usados para realizar uma triagem e detectar profissionais com alto risco de síndrome da apneia obstrutiva do sono, de sonolência diurna excessiva e fadiga. Este estudo teve como objetivo aplicar questionários validados para triagem dos distúrbios do sono e do humor em pilotos civis e analisar os resultados obtidos com a aplicação desses instrumentos. Foram coletados dados de 44 pilotos civis por meio de quatro instrumentos: um questionário para a caracterização sociodemográfica e ocupacional da amostra, a Escala de Sonolência de Epworth para avaliar a presença de sonolência diurna excessiva, o Questionário de Berlim para avaliar a Síndrome da Apneia Obstrutiva do Sono e a Escala de Humor de Brunel para avaliar o estado de humor. A Escala de Sonolência de Epworth mostrou que 25% dos pilotos apresentaram pontuação para sonolência diurna excessiva. De acordo com o Questionário de Berlim, 29,5% apresentaram alto risco para a Síndrome da Apneia Obstrutiva do Sono e pela Escala de Humor de Brunel, o domínio vigor, teve a média mais alta (5,09 ±4,06). Portanto, a utilização dos questionários nos exames de admissão e nos periódicos, pode auxiliar na identificação precoce e no monitoramento de distúrbios do sono e dos estados de humor ao longo do tempo em pilotos civis, priorizando aqueles que deverão ser encaminhados para realizarem estudos do sono.


Sleep disorders and mood state changes, when untreated, are associated with loss of productivity and accidents at work, resulting in injuries and fatality. These disorders are underdiagnosed and undertreated in clinical contexts due to them being asymptomatic and the prohibitive cost of polysomnography exams. For this reason, questionnaires are used to screen and detect professionals at high risk for obstructive sleep apnea syndrome, excessive daytime sleepiness, and fatigue. This study aimed at applying validated questionnaires for screening sleep and mood disorders in civilian pilots and analyzing the results obtained with the application of these instruments. Data were collected from 44 civilian pilots using four instruments: a questionnaire for sociodemographic and occupational characterization of the sample; the Epworth Sleepiness Scale to assess the presence of excessive daytime sleepiness; the Berlin Questionnaire to assess Obstructive Sleep Apnea Syndrome; and the Brunel Mood Scale to assess the mood state. The Epworth Sleepiness Scale showed that 25% of the pilots presented scores for excessive daytime sleepiness. According to the Berlin Questionnaire, 29.5% were at high risk for Obstructive Sleep Apnea Syndrome, and according to the Brunel Mood Scale, the vigor domain presented the highest mean (5.09 ± 4.06). Therefore, the use of questionnaires in admission and periodic exams can assist in the early identification and monitoring of sleep disorders and mood states over time in civilian pilots, prioritizing those who should be referred to sleep studies.

ABSTRACT

Objetivo del estudio: evaluar si la puntuación de Mallampati modificada (MMS) puede predecir la presencia y la gravedad del síndrome de apnea obstructiva del sueño (AOS) en un grupo de pacientes que roncaban y presentaban apnea en los hospitales universitarios de Al-Azhar, El Cairo, Egipto y el Hospital Almoosa, Alhasa, Arabia Saudita. Métodos: Se realizó un estudio retrospectivo de pacientes que roncaban y presentaron apnea remitidos a un laboratorio del sueño para el diagnóstico de AOS mediante polisomnograma completo durante la noche desde enero de 2017 a noviembre de 2020. Se utilizó el índice de apnea-hipopnea (IAH) para categorizar la gravedad apnea del sueño. Se registraron edad, sexo, SMM, índice de masa corporal (IMC), comorbilidades, sueño y parámetros de laboratorio. Además, se registraron exámenes completos de Otorrinolaringología, Neurología y Medicina Interna. Resultados: El estudio se realizó en 350 pacientes que cumplían los criterios de inclusión con una edad media de 51,3 ± 14,3 años con un rango de 14 a 81 años. Más de la mitad de ellos (58,6%) eran hombres, el IMC medio fue de 35,1 ± 8,8 kg / m2 y el MMS medio fue de 4,7 ± 1,6 con aproximadamente el 65% de los pacientes agrupados en clases III y IV. Se diagnosticó AOS (IAH> 5) en 278 (79,4%) pacientes. Significativamente, la AOS se detectó más entre los hombres, aquellos con mayor edad, IMC, MMS y aquellos con diabetes mellitus tipo 2 (DM2). Una evaluación adicional mostró una correlación positiva significativa entre el IMC y el MMS con la gravedad de la AOS (ρ = 0,23, P <0,001 y ρ = 0,36, P <0,001) respectivamente. Conclusión: MMS es una herramienta útil para predecir la presencia y la gravedad de la AOS en pacientes que roncan. El IMC y el sexo masculino son predictores independientes


Aim of the study: To assess if the modified Mallampati score (MMS) can predict the presence and the severity of obstructive sleep apnea syndrome (OSA) in a group of patients who had snoring and witnessed apnea from Al -Azhar university hospitals, Cairo, Egypt, and Almoosa Hospital, Alhasa, Saudi Arabia. Methods: A retrospective study was done for patients who had snoring and witnessed apnea referred to a sleep lab for the diagnosis of OSA by overnight full polysomnogram from January 2017 to November 2020. Apnea-hypopnea index (AHI) was used to categorize the severity of sleep apnea. Age, sex, MMS, body mass index (BMI), comorbidities, sleep and laboratory parameters were recorded. Also, full Otorhinolaryngological, Neurological and Internal medicine examinations were recorded. Results: The study was carried out on 350 patients fulfilling the inclusion criteria with a mean age 51.3 ± 14.3 years ranging from 14 to 81 years. More than half of them (58.6%) were males, the mean BMI was 35.1 ± 8.8 kg/m2 and the mean MMS was 4.7 ± 1.6 with about 65% of patients grouped in classes III and IV. OSA (AHI>5) was diagnosed in 278 (79.4%) patients. Significantly, OSA was more detected among males, those with increased age, BMI, MMS, and those with type 2 diabetes mellitus (T2DM). Further evaluation showed a significant positive correlation between both BMI and MMS with the severity of OSA (ρ =0.23, P<0.001 and ρ =0.36, P<0.001) respectively. Conclusion: MMS is a useful tool to predict the presence as well as the severity of OSA in snoring patients. BMI and male gender are independent predictors

ABSTRACT

Resumo Fundamento: A obesidade afeta a adolescência, podendo levar à síndrome metabólica (SM) e disfunção endotelial, um marcador precoce de risco cardiovascular. Apesar de a obesidade ser fortemente associada à síndrome da apneia obstrutiva do sono (SAOS), ainda não está claro o papel da SAOS na função endotelial em adolescentes obesos. Objetivo: Investigar se a obesidade durante a adolescência leva à SM e/ou SAOS e causa disfunção endotelial nesses indivíduos. Além disso, estudamos a possível associação dos fatores de risco para SM e do índice de apneia e hipopneia (IAH) com disfunção endotelial. Métodos: Estudamos 20 adolescentes obesos sedentários (AO; 14,2±1,6 anos, 100,9±20,3kg), e 10 adolescentes eutróficos (AE, 15,2±1,2 anos, 54,4±5,3kg) pareados por sexo. Avaliamos os fatores de risco para SM (critérios da Federação Internacional de Diabetes), função vascular (dilatação mediada pelo fluxo, DMF), capacidade funcional (VO2pico) e presença de SAOS (IAH > 1 evento/hora, pela polissonografia). Consideramos um p<0,05 como estatisticamente significativo. Resultados: AO apresentaram maior circunferência da cintura (CC), gordura corporal, triglicerídeos, pressão arterial sistólica (PAS) e diastólica (PAD), maiores níveis de LDL e menores HDL e VO2pico em comparação a AE. Não houve diferença no IAH entre os grupos. AO apresentaram menor DMF que AE (6,17±2,72 vs. 9,37±2,20%, p=0,005). Observou-se uma associação entre DMF e CC (R=-0,506, p=0,008) e entre DMF e PAS (R=-0,493, p=0,006). Conclusão: Em adolescentes, a obesidade associou-se à SM e causou disfunção endotelial. CC e PAS aumentadas poderiam estar envolvidas nessa alteração. SAOS foi detectada na maioria dos adolescentes independentemente de obesidade. (Arq Bras Cardiol. 2021; 116(4):795-803)


Abstract Background: Obesity affects adolescence and may lead to metabolic syndrome (MetS) and endothelial dysfunction, an early marker of cardiovascular risk. Albeit obesity is strongly associated with obstructive sleep apnea (OSA), it is not clear the role of OSA in endothelial function in adolescents with obesity. Objective: To investigate whether obesity during adolescence leads to MetS and/or OSA; and causes endothelial dysfunction. In addition, we studied the possible association of MetS risk factors and apnea hypopnea index (AHI) with endothelial dysfunction. Methods: We studied 20 sedentary obese adolescents (OA; 14.2±1.6 years, 100.9±20.3kg), and 10 normal-weight adolescents (NWA, 15.2±1.2 years, 54.4±5.3kg) paired for sex. We assessed MetS risk factors (International Diabetes Federation criteria), vascular function (Flow-Mediated Dilation, FMD), functional capacity (VO2peak) and the presence of OSA (AHI>1event/h, by polysomnography). We considered statistically significant a P<0.05. Results: OA presented higher waist (WC), body fat, triglycerides, systolic (SBP) and diastolic blood pressure (DBP), LDL-c and lower HDL-c and VO2peak than NWA. MetS was presented in the 35% of OA, whereas OSA was present in 86.6% of OA and 50% of EA. There was no difference between groups in the AHI. The OA had lower FMD than NWA (6.17±2.72 vs. 9.37±2.20%, p=0.005). There was an association between FMD and WC (R=-0.506, p=0.008) and FMD and SBP (R=-0.493, p=0.006). Conclusion: In adolescents, obesity was associates with MetS and caused endothelial dysfunction. Increased WC and SBP could be involved in this alteration. OSA was observed in most adolescents, regardless of obesity. (Arq Bras Cardiol. 2021; 116(4):795-803)

ABSTRACT

RESUMO A eficácia da terapia fonoaudiológica está comprovada para a apneia obstrutiva do sono (AOS), principalmente para a população adulta. Entretanto, estudos com população acima de 65 anos são escassos. Assim, o objetivo do presente estudo foi analisar a evolução clínica longitudinal de um sujeito idoso com AOS submetido à terapia miofuncional orofacial (TMO). Caso clínico, sexo masculino, 72 anos, com AOS, submetido à TMO após ter realizado avaliação clínica, exames de polissonografia (PSG) e avaliação clínica otorrinolaringológica, bem como a aplicação da escala de sonolência de Epworth, a classificação de Mallampati e a avaliação fonoaudiológica miofuncional orofacial em três momentos distintos: antes da TMO, após a TMO e após 22 meses da TMO. A TMO se configurou na realização de exercícios isométricos e isotônicos para região orofacial e faríngea, treino funcional em sessões semanais de 30 minutos, durante cinco meses, quando, então, as sessões foram espaçadas. Após os 22 meses de TMO, observaram-se evoluções nos parâmetros objetivos e subjetivos relativos ao sono, que foram analisados e identificados por meio de uma nova polissonografia (PSG), com os seguintes dados: exame basal, 24,5 eventos/hora e último exame de 4,63 eventos/hora. Verificou-se acentuada melhora da sonolência diurna excessiva e, ainda, melhora dos parâmetros miofuncionais orofaciais. Deste modo, pôde-se constatar que a TMO demonstrou resultados eficientes e eficazes na intervenção e no tratamento terapêutico fonoaudiológico, tendo como base a AOS do paciente idoso. Ressalta-se que tais resultados foram acompanhados e controlados por meio de avaliação multidisciplinar de modo longitudinal.


ABSTRACT The effectiveness of speech-language therapy is proven for obstructive sleep apnea (OSA), especially for the adult population. However, studies with a population over 65 years are scarce. Thus, the aim of the present study was to analyze the longitudinal clinical evolution of an OSA elderly subject undergoing Orofacial Myofunctional Therapy (OMT). Male clinical case, 72 years old, with OSA submitted to OMT, polysomnography (PSG) exams, otorhinolaryngological clinical evaluation, Epworth sleepiness scale application, Mallampati classification and orofacial myofunctional speech evaluation in 3 different moments in time (before OMT, after OMT and after 22 months of OMT). OMT was configured to perform isometric and isotonic exercises for the orofacial and pharyngeal regions and functional training in weekly sessions of 30 minutes for 5 months. After that period, the sessions were spaced for biweekly, monthly and quarterly. After 22 months of OMT, an evolution was observed in the objective and subjective parameters related to sleep, identified by polysomnography (baseline test: 24.5 events / hour and last test of 4.63 events per hour), improvement in excessive daytime sleepiness and improvement of myofunctional orofacial parameters. Thus, it was observed that OMT demonstrated efficient and effective results of speech therapy intervention and therapeutic treatment based on OSA in this case report of an elderly person. It is noteworthy that such results were monitored and controlled through multidisciplinary evaluation in a longitudinal way.

ABSTRACT

ABSTRACT Objective: Obstructive sleep apnea (OSA) is associated with an increased risk of mortality and cardiometabolic diseases. The STOP-Bang questionnaire is a tool to screen populations at risk of OSA and prioritize complementary studies. Our objective was to evaluate the clinical utility of this questionnaire in identifying patients at an increased risk of mortality after discharge in a cohort of hospitalized patients. Methods: This was a prospective cohort study involving consecutive patients admitted to an internal medicine unit between May and June of 2017 who were reevaluated three years after discharge. At baseline, we collected data on comorbidities (hypertension, obesity, diabetes, and fasting lipid profile) and calculated STOP-Bang scores, defining the risk of OSA (0-2 score, no risk; ≥ 3 score, risk of OSA; and ≥ 5 score, risk of moderate-to-severe OSA), which determined the study groups. We also recorded data regarding all-cause and cardiovascular mortality at the end of the follow-up period. Results: The sample comprised 435 patients. Of those, 352 (80.9%) and 182 (41.8%) had STOP-Bang scores ≥ 3 and ≥ 5, respectively. When compared with the group with STOP-Bang scores of 0-2, the two groups showed higher prevalences of obesity, hypertension, diabetes, and dyslipidemia. Multivariate analysis showed an independent association between cardiovascular mortality and STOP-Bang score ≥ 5 (adjusted hazard ratio = 3.12 [95% CI, 1.39-7.03]; p = 0.01). Additionally, previous coronary heart disease was also associated with cardiovascular mortality. Conclusions: In this cohort of hospitalized patients, STOP-Bang scores ≥ 5 were able to identify patients at an increased risk of cardiovascular mortality three years after discharge.


RESUMO Objetivo: A apneia obstrutiva do sono (AOS) está associada a um risco maior de mortalidade e doenças cardiometabólicas. O questionário STOP-Bang é uma ferramenta para rastrear populações em risco de AOS e assim priorizar estudos complementares. Nosso objetivo foi avaliar a utilidade clínica desse questionário na identificação de pacientes com risco aumentado de mortalidade após a alta em uma coorte de pacientes hospitalizados. Métodos: Estudo de coorte prospectivo com pacientes consecutivos internados em uma unidade de medicina interna entre maio e junho de 2017 que foram reavaliados três anos após a alta. No momento basal, coletamos dados sobre comorbidades (hipertensão, obesidade, diabetes e perfil lipídico em jejum) e calculamos as pontuações no STOP-Bang, definindo o risco de OSA (pontuação 0-2, sem risco; pontuação ≥ 3, risco de AOS; e pontuação ≥ 5, risco de AOS moderada a grave), que determinou os grupos de estudo. Também registramos dados sobre mortalidade por todas as causas e mortalidade cardiovascular ao final do período de acompanhamento. Resultados: Foram incluídos 435 pacientes. Desses, 352 (80,9%) e 182 (41,8%) apresentaram pontuações no STOP-Bang ≥ 3 e ≥ 5, respectivamente. Quando comparados com o grupo com pontuação no STOP-Bang de 0-2, os outros dois grupos apresentaram prevalências mais elevadas de obesidade, hipertensão, diabetes e dislipidemia. A análise multivariada mostrou uma associação independente entre mortalidade cardiovascular e pontuação no STOP-Bang ≥ 5 (razão de risco ajustada = 3,12 [IC95%, 1,39-7,03]; p = 0,01). Além disso, doença coronariana prévia também foi associada à mortalidade cardiovascular. Conclusões: Nesta coorte de pacientes hospitalizados, pontuações no STOP-Bang ≥ 5 foram capazes de identificar pacientes com risco aumentado de mortalidade cardiovascular três anos após a alta.

ABSTRACT

ABSTRACT Objective: Impaired respiratory mechanics and gas exchange may contribute to sleep disturbance in patients with COPD. We aimed to assess putative associations of different domains of lung function (airflow limitation, lung volumes, and gas exchange efficiency) with polysomnography (PSG)-derived parameters of sleep quality and architecture in COPD. Methods: We retrospectively assessed data from COPD 181 patients ≥ 40 years of age who underwent spirometry, plethysmography, and overnight PSG. Univariate and multivariate linear regression models predicted sleep efficiency (total sleep time/total recording time) and other PSG-derived parameters that reflect sleep quality. Results: The severity of COPD was widely distributed in the sample (post-bronchodilator FEV1 ranging from 25% to 128% of predicted): mild COPD (40.3%), moderate COPD (43.1%), and severe-very severe COPD (16.6%). PSG unveiled a high proportion of obstructive sleep apnea (64.1%) and significant nocturnal desaturation (mean pulse oximetry nadir = 82.2% ± 6.9%). After controlling for age, sex, BMI, apnea-hypopnea index, nocturnal desaturation, comorbidities, and psychotropic drug prescription, FEV1/FVC was associated with sleep efficiency (β = 25.366; R2 = 14%; p < 0.001), whereas DLCO predicted sleep onset latency (β = −0.314; R2 = 13%; p < 0.001) and rapid eye movement sleep time/total sleep time in % (β = 0.085; R2 = 15%; p = 0.001). Conclusions: Pulmonary function variables reflecting severity of airflow and gas exchange impairment, adjusted for some potential confounders, were weakly related to PSG outcomes in COPD patients. The direct contribution of the pathophysiological hallmarks of COPD to objectively measured parameters of sleep quality seems to be less important than it was previously assumed.


RESUMO Objetivo: O comprometimento da mecânica respiratória e das trocas gasosas pode contribuir para distúrbios do sono em pacientes com DPOC. Objetivamos avaliar associações putativas de diferentes domínios da função pulmonar (limitação do fluxo aéreo, volumes pulmonares e eficiência das trocas gasosas) com parâmetros da qualidade e arquitetura do sono na DPOC derivados da polissonografia (PSG). Métodos: Avaliamos retrospectivamente dados de 181 pacientes com DPOC e idade ≥ 40 anos que foram submetidos a espirometria, pletismografia e PSG de noite inteira. Modelos de regressão linear univariada e multivariada foram utilizados para avaliar a associação de variáveis de função pulmonar com a eficiência do sono (tempo total de sono/tempo total de registro) e outros parâmetros derivados da PSG que refletem a qualidade do sono. Resultados: A gravidade da DPOC foi bem distribuída na amostra (VEF1 pós-broncodilatador variando de 25% a 128% do previsto): DPOC leve (40,3%), DPOC moderada (43,1%) e DPOC grave-muito grave (16,6%). A PSG revelou uma alta frequência de apneia obstrutiva do sono (64,1%) e dessaturação noturna significativa (nadir médio da oximetria de pulso = 82,2% ± 6,9%). Após controle para idade, sexo, IMC, índice de apneia-hipopneia, dessaturação noturna, comorbidades e prescrição de psicotrópicos, a relação VEF1/CVF apresentou associação com a eficiência do sono (β = 25,366; R2 = 14%; p < 0,001), enquanto a DLCO previu a latência para o início do sono (β = −0,314; R2 = 13%; p < 0,001) e o tempo de sono rapid eye movement/tempo total de sono em % (β = 0,085; R2 = 15%; p = 0,001). Conclusões: As variáveis de função pulmonar que refletem a gravidade do comprometimento do fluxo aéreo e das trocas gasosas, ajustadas para alguns potenciais fatores de confusão, apresentaram fraca relação com os resultados da PSG nos pacientes com DPOC. A contribuição direta das características fisiopatológicas da DPOC para os parâmetros da qualidade do sono medidos objetivamente parece ser menos importante do que se supunha anteriormente.

ABSTRACT

Congenital central hypoventilation syndrome (CCHS) and rapid-onset obesity syndrome with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) are rare causes of hypoventilation during sleep in the pediatric population. This group of disorders are characterized by the absence or decrease in the automatic control of ventilation, decreased sensitivity of chemoreceptors to CO2, causing hypoventilation during sleep and even in wakefulness, in the most severe cases. For these reasons it is important to diagnose and treat them promptly. The objective of this review is to provide current and complete literature, to be able to identify, treat and refer this group of children early, and thus reduce the complications and/or associated comorbidities in the short and long term, improving their quality of life.


El síndrome de hipoventilación central congénita (CCHS) y síndrome de obesidad de inicio rápido con disfunción hipotalámica, hipoventilación y desregulación autonómica (ROHHAD), son causas poco comunes de hipoventilación durante el sueño en la población pediátrica. Este grupo de trastornos se caracterizan por ausencia o disminución en el control automático de la ventilación, sensibilidad disminuida de los quimioreceptores al CO2, provocando hipoventilación durante el sueño e incluso en vigilia, en los casos más severos. Por estas razones es importante diagnosticarlos y tratarlos oportunamente. El objetivo de esta revisión es proporcionar literatura actual y completa, para poder identificar, tratar y referir a éste grupo de niños tempranamente, y así disminuir las complicaciones y/o comorbilidades asociadas a corto y largo plazo, mejorando su calidad de vida.

ABSTRACT

Sleep is a complex physiological process of great significance to physical and mental health, and its research scope involves multiple disciplines. At present, the quantitative analysis of sleep mainly relies on the "gold standard" of polysomnography (PSG). However, PSG has great interference to the human body and cannot reflect the hemodynamic status of the brain. Functional near infrared spectroscopy (fNIRS) is used in sleep research, which can not only meet the demand of low interference to human body, but also reflect the hemodynamics of brain. Therefore, this paper has collected and sorted out the related literatures about fNIRS used in sleep research, concluding sleep staging research, clinical sleep monitoring research, fatigue detection research, etc. This paper provides a theoretical reference for scholars who will use fNIRS for fatigue and sleep related research in the future. Moreover, this article concludes the limitation of existing studies and points out the possible development direction of fNIRS for sleep research, in the hope of providing reference for the study of sleep and cerebral hemodynamics.

ABSTRACT

Aiming at the limitations of clinical diagnosis of Parkinson's disease (PD) with rapid eye movement sleep behavior disorder (RBD), in order to improve the accuracy of diagnosis, an intelligent-aided diagnosis method based on few-channel electroencephalogram (EEG) and time-frequency deep network is proposed for PD with RBD. Firstly, in order to improve the speed of the operation and robustness of the algorithm, the 6-channel scalp EEG of each subject were segmented with the same time-window. Secondly, the model of time-frequency deep network was constructed and trained with time-window EEG data to obtain the segmentation-based classification result. Finally, the output of time-frequency deep network was postprocessed to obtain the subject-based diagnosis result. Polysomnography (PSG) of 60 patients, including 30 idiopathic PD and 30 PD with RBD, were collected by Nanjing Brain Hospital Affiliated to Nanjing Medical University and the doctor's detection results of PSG were taken as the gold standard in our study. The accuracy of the segmentation-based classification was 0.902 4 in the validation set. The accuracy of the subject-based classification was 0.933 3 in the test set. Compared with the RBD screening questionnaire (RBDSQ), the novel approach has clinical application value.

ABSTRACT

OBJECTIVES@#This study aims to investigate the incidence and severity of obstructive sleep apnea (OSA) in cleft patients with velopharyngeal insufficiency (VPI) after pharyngeal flap surgery (PFS) and explore the influence of operation age.@*METHODS@#A retrospective study was conducted in 82 cleft patients after PFS. The patients were divided into two groups according to their age at the time of surgery. The incidence and severity of OSA were assessed at least 1.2 years (mean 6.0 years) postoperatively by polysomnography (PSG).@*RESULTS@#The incidence rates of OSA were 20% in the adult group and 31% in the child group. No significant difference was found between the two groups (@*CONCLUSIONS@#Some patients still have OSA average of 6.0 years after PFS, and operation ageis unrelated to the incidence and severity of OSA.

ABSTRACT

OBJECTIVE@#To study the clinical features of sleep-disordered breathing (SDB) in children with neuromuscular disease (NMD).@*METHODS@#A retrospective analysis was performed on the medical data of 18 children who were diagnosed with NMD and underwent polysomnography (PSG) (NMD group). Eleven children without NMD who had abnormal sleeping habit and normal sleep structure on PSG were enrolled as the control group. The two groups were compared in terms of the daily and nocturnal symptoms of SDB, incidence rate of obstructive sleep apnea (OSA), pulmonary function, end-tidal partial pressure of carbon dioxide (PetCO@*RESULTS@#In the NMD group, 16 children (89%) had related daily and nocturnal symptoms of SDB, and the youngest age was 1 year at the onset of such symptoms. Compared with the control group, the NMD group had significant reductions in total sleep time and sleep efficiency (@*CONCLUSIONS@#There is a high proportion of children with SDB among the children with NMD, and SDB can be observed in the early stage of NMD, which results in the damage of sleep structure and the reduction in sleep efficiency. Respiratory events are mainly obstructive events, and oxygen reduction events are mainly observed during REM sleep.

ABSTRACT

Sleep stage classification is a necessary fundamental method for the diagnosis of sleep diseases, which has attracted extensive attention in recent years. Traditional methods for sleep stage classification, such as manual marking methods and machine learning algorithms, have the limitations of low efficiency and defective generalization. Recently, deep neural networks have shown improved results by the capability of learning complex pattern in the sleep data. However, these models ignore the intra-temporal sequential information and the correlation among all channels in each segment of the sleep data. To solve these problems, a hybrid attention temporal sequential network model is proposed in this paper, choosing recurrent neural network to replace traditional convolutional neural network, and extracting temporal features of polysomnography from the perspective of time. Furthermore, intra-temporal attention mechanism and channel attention mechanism are adopted to achieve the fusion of the intra-temporal representation and the fusion of channel-correlated representation. And then, based on recurrent neural network and inter-temporal attention mechanism, this model further realized the fusion of inter-temporal contextual representation. Finally, the end-to-end automatic sleep stage classification is accomplished according to the above hybrid representation. This paper evaluates the proposed model based on two public benchmark sleep datasets downloaded from open-source website, which include a number of polysomnography. Experimental results show that the proposed model could achieve better performance compared with ten state-of-the-art baselines. The overall accuracy of sleep stage classification could reach 0.801, 0.801 and 0.717, respectively. Meanwhile, the macro average F1-scores of the proposed model could reach 0.752, 0.728 and 0.700. All experimental results could demonstrate the effectiveness of the proposed model.

ABSTRACT

ABSTRACT Objective: Uric acid has been shown to be related to the severity of obstructive sleep apnoea syndrome (OSAS) in adults. We assessed the role of uric acid in OSAS in a cohort of older patients. Methods: A total of 164 patients aged >65 years, admitted to our sleep laboratory between January 1st, 2016 and July 1st, 2018 with a complaint of snoring, underwent overnight polysomnography and were retrospectively evaluated. Results: A total of 126 patients who fulfilled the inclusion criteria (mean age 69.16±3.68 years, 56% men) were included. The control group was comprised of 14 patients, while the OSAS group consisted of 112 patients (31 mild, 44 moderate and 37 severe cases). No differences were observed in age, sex, hip circumference, waist/hip ratio or comorbidities between the groups. The Epworth Sleepiness Scale score, body mass index (BMI), and waist circumference were significantly higher in OSAS patients than in controls (p=0.001, p=0.02, and p=0.36, respectively). Uric acid was not correlated with any of the sleep parameters, and no significant differences were detected between the groups. Hyperuricemic patients were similar in terms of sleep parameters and comorbidities in comparison with the other patients. Conclusions: No relationship was observed between uric acid level and OSAS severity, as defined by the apnoea-hypopnea index. Further studies are needed to determine the value of uric acid as a marker of OSAS, after controlling for cardiovascular comorbidities, in older patients with this syndrome.


RESUMO Objetivo: o ácido úrico mostrou estar relacionado à gravidade da síndrome da apneia obstrutiva do sono (SAOS) em adultos. Avaliamos o papel do ácido úrico na SAOS em uma coorte de pacientes idosos. Métodos: Um total de 164 pacientes com idade >65 anos, admitidos em nosso laboratório do sono entre 1º de janeiro de 2016 e 1º de julho de 2018 com queixa de ronco, foram submetidos à polissonografia durante a noite e avaliados retrospectivamente. Resultados: Foram incluídos 126 pacientes que preencheram os critérios de inclusão (média de idade 69,16±3,68 anos, 56% homens). O grupo controle foi composto por 14 pacientes, enquanto o grupo SAOS foi composto por 112 pacientes (31 leves, 44 moderados e 37 graves). Não foram observadas diferenças na idade, sexo, circunferência do quadril, relação cintura/quadril ou comorbidades entre os grupos. O escore da Escala de Sonolência de Epworth, o índice de massa corporal (IMC) e a circunferência da cintura foram significativamente maiores nos pacientes com SAOS do que nos controles (p=0,001, p=0,02 e p=0,36, respectivamente). O ácido úrico não se correlacionou com nenhum dos parâmetros do sono e não foram detectadas diferenças significativas entre os grupos. Os pacientes hiperuricêmicos não apresentaram diferença em termos de parâmetros de sono ou comorbidades dos demais pacientes. Conclusões: Não foi observada relação entre o nível de ácido úrico e a gravidade da SAOS, definida pelo índice de apneia-hipopneia. Mais estudos são necessários para determinar o valor do ácido úrico como marcador de SAOS, após controle de comorbidades cardiovasculares, em pacientes idosos com SAOS.

ABSTRACT

Introducción: La apnea obstructiva del sueño (AOS) es una entidad frecuente, presente en un 9% a 38%, pero con un subregistro importante del 85%1. Clásicamente, se observa en hombres de edad mediana, obesos y somnolientos, relacionándose estrechamente con múltiples comorbilidades de tipo cardiovascular, respiratorio y metabólico, que genera un alto costos en los sistemas de salud. El objetivo de este estudio fue determinar la frecuencia e identificar los factores clínicos asociados a la apnea obstructiva del sueño, en la población adulta de un centro especializado de Cali, Colombia. Materiales y Métodos: Estudio observacional, analítico de casos y controles anidado en una cohorte. Se analizaron registros de polisomnografías de primera vez en adultos con sospecha clínica de AOS en un centro especializado. A través de estadística descriptiva, se resumieron las características de la población de estudio. Las asociaciones se determinaron a través de OR, IC95% y se tomó como significante valores de p ≤ 0,05 para las pruebas estadísticas. A través de una regresión logística multivariada se identificó un modelo de 6 variables que explican de manera independiente el evento. Resultados: Se analizaron 566 polisomnografías, la prevalencia de la AOS fue 85.3% (483 de 566; IC95%82, 4-88.35%), la edad media fue 51.80 ± 13.73 años, el 50% fueron hombres. El modelo final incluyo sexo masculino (OR 4.46 IC95% 2.04-8.04, p < 0.000), hipertensión (OR 3.78 IC95% 2.48-8.04, p < 0,000), Mallampati grado IV (OR 4.14, IC95% 2.41-7.10, p < 0.000) y somnolencia excesiva (OR 5.70 IC95% 1.66-19.53, p < 0.006) y peso normal (OR 0.48 IC95% 0.24-0.97, p < 0.043). Conclusión: La probabilidad predictiva demostró que ser hombre, hipertenso con Mallampati grado IV y somnolencia excesiva, se asocian de manera independiente a la AOS, mientras que el peso normal disminuyó el riesgo

ABSTRACT

Introduction: Obstructive sleep apnea (OSA) is a common entity present in 9% to 38%, but with an important underreporting of 85%. Classically, it is observed in middle-aged, obese and sleepy men, closely related to multiple comorbidities of cardiovascular, respiratory and metabolic and is associated with increased mortality. Recent studies indicate that majority of people with type 2 diabetes also has OSA. The aim of this study was to assess the prevalence and severity of OSA and risk factors contributing to it among people with chronic and severe type 2 diabetes. Methods A total of 203 people with type 2 diabetes (mean age: 54 ± 8 years, 145 males, 58 females, HbA1c ≥ 7% [53mmol/mol] types, generating high costs of health systems.10 The purpose of this study was to determine the frequency and identify the clinical factors associated with obstructive sleep apnea within the adult population of a specialized center in Cali, Colombia. Materials and Methods: Observational, analytical case-control study nested within a cohort. First-time polysomnography records were analyzed in adults with clinical suspicion of OSA in a specialized center. The characteristics of the study population were summarized through descriptive statistics. Associations were determined through OR, 95% CI and values of p ≤ 0.05 taken as significant for the statistical tests. Through multivariate logistic regression, a 6-variable model was identified, where the 6 variables independently explain the event. Results: We analyzed 566 polysomnographies, where the prevalence of OSA was 85.3% (483 of 566, 95% CI 82.4-88.35%), the mean age was 51.80 ± 13.73 years and 50% were men The final model included male gender (OR 4.46 95% CI 2.04-8.04, p <0.000), hypertension (OR 3.78 95% CI 2.48-8.04, p <0.000), Mallampati grade IV (OR 4.14, 95% CI 2.41-7.10, p <0.000) and excessive sleepiness (OR 5.70 95% CI 1.66-19.53, p <0.006) and normal weight (OR 0.48 95% CI 0.24-0.97, p <0.043). Conclusion: The predictive probability showed that being male, hypertensive with Mallampati grade IV and excessive sleepiness are associated independently with OSA, while normal weight decreased the risk

ABSTRACT

ABSTRACT Introduction: A diagnosis of rapid eye movement sleep behavior disorder (RBD) currently requires confirmation with polysomnography (PSG). However, PSG may not be sufficiently available. In these situations, a clinical diagnostic measure might be useful. Objective: To validate the Brazilian Portuguese version of RBD screening questionnaire (RBDSQ) for patients with Parkinson's disease (PD). Methods: Using detailed clinical interviews and PSG analysis (diagnostic gold standard), a convenience sample of 69 subjects was divided into the following subgroups: patients with PD and RBD (PD+RBD; n=50) and patients with PD alone (PD-RBD; n=19). Results: RBDSQ-BR showed adequate internal consistency (Cronbach's α=0.809) and, except for item 8, adequate item-test correlation. The retest performed in a second sample (n=13, consecutive) showed high agreement for total score (intraclass correlation coefficient, ICC=0.863) and acceptable agreement for items 2, 3, 6.2, 6.3, 7, and 8 (K>0.60). The receiver operating characteristic (ROC) curve analysis had an area under the curve (AUC) of 0.728. A cut-off score of 4 enabled the correct diagnosis of 76.8% subjects and provided the best balance between sensitivity (84%) and specificity (57.9%), with a 2.0 likelihood ratio of a positive result (LR+) and a 0.3 likelihood ratio of a negative result (LR-). Items 2 and 6.2 had 84.2% specificity and 3.2 LR+. Combined items 1+2+6.2, 2+6.1, and 6.1+6.2 increased the specificity to 94.7%, with LR+ ranging from 6.1 to 7.6. Conclusions: RBDSQ-BR is a reliable instrument, which may be useful for RBD diagnosis of Brazilian patients with PD. The instrument is also valid and may help in a better selection of cases for a more detailed clinical evaluation or even PSG analysis.


RESUMO Introdução: O diagnóstico do transtorno comportamental do sono REM (TCSREM) implica na realização da polissonografia (PSG), mas sua disponibilidade pode não ser suficiente. Portanto, meios clínicos para o diagnóstico podem ser úteis. Objetivo: Validar para a língua portuguesa falada no Brasil o questionário de triagem do TCSREM (QT-TCSREM) em pacientes portadores de doença de Parkinson (DP). Métodos: Uma amostra por conveniência composta de 69 indivíduos foi dividida em portadores de DP com TCSREM (n=50) e DP sem TCSREM (n=19) através de entrevista clínica detalhada e análise da PSG. Resultados: QT-TCSREM-BR apresentou consistência interna adequada (α de Cronbach=0,809) e, exceto pelo item 8, correlação item-total adequada. Reteste feito em uma segunda amostra (n=13, consecutivos) evidenciou concordância elevada para o escore total (coeficiente de correlação intraclasse, CCI=0,863) e aceitável para os itens 2, 3, 6.2, 6.3, 7 e 8 (K>0,60). Análise da curva característica de operação do receptor (COR) obteve uma área sob a curva de 0,728. O corte 4 permitiu o diagnóstico correto de 76,8% dos indivíduos e apresentou o melhor equilíbrio entre sensibilidade (84%) e especificidade (57,9%), com uma razão de verossimilhança de um resultado positivo (RV+) 2,0 e de um resultado negativo (RV-) 0,3. Os itens 2 e 6.2 obtiveram especificidade 84,2% e RV+ 3,2. Itens combinados 1+2+6,2, 2+6,1 e 6,1+6,2 aumentaram a especificidade para 94,7%, com RV+ variando de 6,1 até 7,6. Conclusões: O QT-TCSREM-BR é um instrumento confiável que pode ser útil para o diagnóstico do TCSREM em pacientes com DP no Brasil. O instrumento também é válido e pode auxiliar numa melhor seleção de casos a serem submetidos a uma avaliação mais detalhada ou até mesmo a uma análise de PSG.

ABSTRACT

ABSTRACT Introduction: The most prescribed treatment option for Obstructive Sleep Apnea (OSA) is CPAP; however, its adherence is limited. Oral Appliance therapy (OAT) is frequently an option or even an adjuvant, being the mandibular advancement Oral Appliance (OAm) the most used prescription. It modifies the upper airway, improving the airway patency. OAm construction is based on the occlusal plane to disocclusion. In this study, the DIORS® appliance was used, a singular OAm, based on Neuro-Occlusal Rehabilitation concepts, that uses Camper's plane as a disocclusion reference, in order to achieve neuromuscular balance and functional stability. Objective: This study primarily aimed to assess the DIORS® effectiveness in relation to clinical and polysomnographic outcomes. It was also evaluated if the use of DIORS® is as effective as titrated CPAP to treat CPAP non-adherent patients. Methods: Twenty patients were included in this study. Objective and subjective clinical data were assessed at a sleep laboratory using all-night polysomnography, and Epworth Sleepiness Scale (ESS), taken at three moments: Baseline, CPAP titration, and using DIORS®. Analysis of respiratory parameters as apnea/hypopnea index (AHI), oxyhemoglobin saturation levels, the arousal index and daytime sleepiness were taken as criteria for a successful OAT. Results: Respiratory and arousal parameters improved in both therapies, while DIORS® promoted a better ESS. Conclusion: Results from the present work support that DIORS® is a viable and effective adjuvant therapy for patients with moderate to severe OSA non-adherent to CPAP.


RESUMO Introdução: A opção mais indicada para tratamento da apneia obstrutiva do sono (AOS) é o CPAP; contudo, a aderência é limitada. A Terapia com Aparelho Oral (TAO) é, frequentemente, uma opção, ou mesmo um adjuvante. A prescrição mais utilizada é o Aparelho Oral de avanço mandibular (AOm). O AOm modifica a via aérea superior, melhorando a patência do espaço aéreo. A construção do AOm se baseia no plano de oclusão para desoclusão. No presente estudo, usamos o DIORS®, um AOm diferente, baseado nos conceitos da Reabilitação Neuro-Oclusal (RNO), que utiliza o Plano de Camper como referência da desoclusão para alcançar o equilíbrio neuromuscular e estabilidade funcional. Objetivo: O presente estudo teve como objetivo principal abordar a eficácia do DIORS®, considerando-se os resultados clínicos e polissonográficos. Adicionalmente, foi avaliado, também, se o uso desse AOm é tão eficaz quanto a titulação do CPAP para tratar pacientes com AOS não aderentes ao CPAP. Métodos: Vinte pacientes foram incluídos neste estudo. Dados clínicos objetivos e subjetivos foram avaliados em um laboratório de sono usando polissonografia de noite inteira e a Escala de Sonolência de Epworth (ESE) observando-se três momentos: inicial, titulação do CPAP e usando o DIORS®. Os critérios de sucesso da TAO foram assumidos pela análise dos parâmetros respiratórios como Índice de Apneia e Hipopneia (IAH) e níveis de saturação de oxi-hemoglobina, o índice de despertar e a sonolência diurna. Resultados: Em ambas as terapias, os parâmetros respiratórios e de despertares melhoraram. Adicionalmente, uma melhora na ESE foi alcançada com o DIORS®. Conclusão: Os resultados do presente trabalho apoiam que o DIORS® é uma terapia adjuvante viável e bastante eficaz para pacientes com AOS moderada a grave não aderentes ao CPAP.

ABSTRACT

ABSTRACT Background: Obstructive Sleep Apnea Syndrome (OSAS) is a public health problem of high prevalence and impacts on quality of life, anesthetic complications and cardiovascular diseases. In view of the difficulty in accessing the polysomnography, it is necessary to validate other methods for OSAS diagnostic screening in clinical practice in our country, such as the STOP-Bang questionnaire. Objective: To validate the STOP-Bang questionnaire in Brazilians and evaluate optimal cutoff points. Methods: After translation and back-translation, STOP-Bang questionnaire was applied to 71 individuals previously submitted to polysomnography and classified into control, mild, moderate or severe OSAS. Results: The majority of patients was male (59.2%), white (79%), aged 48.9±13.9 years, and with neck circumference >40 centimeters (73.8%). STOP-Bang score was higher in OSAS mild (median/inter-quartis 25-75%: 5/3.5-6), moderate (4.5/4-5) and severe (5/4-6), versus control (2.5/1-4). The receiver operating characteristic (ROC) curve indicate that scores 3, 4 and 6, present the best specificity values (100, 80 and 92.9%) with acceptable sensitivity (60, 66.7 and 50%) in the mild, moderate and severe OSAS subgroups, respectively. In OSAS group analysis (Apnea Hypopnea Index [AHI] ≥5, <15, ≥15 - <30, ≥30), STOP-Bang cutoff point of 6 was optimal to detect OSAS. Conclusion: STOP-Bang Brazilian version identified OSAS patients with lower sensitivity and higher specificity compared to previous studies. Different cutoff points would improve the performance to detect patients with more severe OSAS.


RESUMO Introdução: A Síndrome da Apneia Obstrutiva do Sono (SAOS) é um problema de saúde pública de alta prevalência e com impacto na qualidade de vida, complicações anestésicas e doenças cardiovasculares. Diante da dificuldade de acesso à realização da polissonografia, é necessário validar outros métodos para a triagem diagnóstica da SAOS na prática clínica no cenário brasileiro, como o questionário STOP-Bang. Objetivos: Validar o questionário STOP-Bang em brasileiros e avaliar os melhores pontos de corte. Método: Após tradução e retrotradução, o STOP-Bang foi aplicado em 71 indivíduos previamente submetidos à polissonografia e classificados em controles e em SAOS leve, moderada e grave. Resultados: A maioria da amostra foi de homens (59,2%), com 48,9±13,9 anos, brancos (79%) e com circunferência do pescoço >40 cm (73,8%). O escore STOP-Bang foi maior na SAOS leve (mediana/interquartis 25-75%: 5/3,5-6), moderada (4,5/4-5) e grave (5/4-6) versus controles (2,5/1-4). A Curva Característica de Operação do Receptor (ROC) indicou que os escores 3, 4 e 6 apresentam os melhores valores de especificidade (100, 80 e 92,9%) e sensibilidade aceitável (60, 66,7 e 50%) nos subgrupos de SAOS leve, moderada e grave, respectivamente. Na análise da amostra com SAOS (IAH ] ≥5, <15, ≥15 - <30, ≥30), o ponto de corte de 6 no STOP-Bang detectou melhor a SAOS. Conclusão: A versão brasileira do STOP-Bang identificou pacientes apneicos com menor sensibilidade e maior especificidade em relação a estudos anteriores. Diferentes pontos de corte melhorariam o desempenho para detectar pacientes com SAOS mais grave.

ABSTRACT

SUMMARY INTRODUCTION: Currently there has been significant growth in the number of patients with suspected obstructive sleep apnea (OSA) referred to sleep clinics. In this sense, screening and stratification methods of the severity of this pathology have become increasingly relevant. OBJECTIVE: To evaluate the performance of the NoSAS and STOP-Bang scores in the screening of OSA in a sleep clinic. METHODS: Prospectively, for 12 months, all patients referred by primary care physicians to our sleep unit for clinical evaluation and who underwent in-lab polysomnography (PSG), also completed the NoSAS score (Neck circumference, Obesity, Snoring, Age, Sex) and STOP-Bang (Snoring, Tiredness, Observed apnea, Pressure (high blood), BMI, Age, Neck circumference, Gender). A ROC (receiver operating characteristic) analysis was used to find the scores that simultaneously maximize sensitivity and specificity for each diagnosis. RESULTS: Of the 294 individuals included, 84% had OSA, of which 28.8% were mild, 34.8% moderate, and 36.4% were severe. USING THE NOSAS SCORE FOR PREDICTING OSA, MODERATE TO SEVERE OSA, AND SEVERE OSA, THE ROC AREA WAS: 0.770 (95% CI: 0.703-0.837), p<0.001, sensitivity of 57.5%, and specificity of 83.0% for a score of 12; 0.746 (95% CI: 0.691-0.802), p<0.001, sensitivity of 68.2% and specificity of 75.4% for a score of 13; 0.686 (95% CI: 0.622-0.749), p<0.001, sensitivity of 71.1% and specificity of 58.3% for a score of 13, respectively. USING THE STOP-BANG SCORE FOR PREDICTING OSA, MODERATE TO SEVERE OSA, AND SEVERE OSA, THE ROC AREA WAS: 0.862 (95% CI: 0.808-0.916), p<0.001, sensitivity of 68.4% and specificity of 85.1% for a score of 5; 0.813 (95% CI: 0.756-0.861), p<0.001, sensitivity of 77.3% and specificity of 66.1% for a score of 5; 0.787 (95% CI: 0.732-0.841), p<0.001, sensitivity of 70.0% and specificity of 79.9% for a score of 6, respectively. CONCLUSIONS: The ROC area was consistently high for both scores confirming the diagnostic ability of the NoSAS and STOP-Bang questionnaires for all OSA severities. Thus, our results suggest that these questionnaires may be a powerful tool for the screening and stratification of patients in the diagnosis of OSA. Overall, the diagnostic ability of the STOP-Bang was higher than the NoSAS.


RESUMO INTRODUÇÃO: Na atualidade tem se verificado um crescimento significativo no número de doentes com suspeita de apneia obstrutiva do sono (AOS) referenciados para consulta do sono. Nesse sentido, instrumentos de rastreio e estratificação da gravidade dessa patologia têm se tornado cada vez mais relevantes. OBJETIVO: Avaliar e comparar o desempenho da escala NoSAS e Stop-Bang para o rastreio de AOS. MÉTODOS: Estudo prospectivo durante 12 meses. Avaliados todos os doentes encaminhados aos cuidados de saúde primários do centro de medicina do sono que completaram o questionário NoSAS (Neck circumference, Obesity, Snoring, Age, Sex), Stop-Bang (Snoring, Tiredness, Observed apnea, Pressure [high blood], BMI, Age, Neck circumference, Gender) e foram submetidos a polissonografia. Utilizou-se uma análise ROC (receiver operating characteristic) para encontrar as pontuações que maximizam simultaneamente a sensibilidade e especificidade para cada diagnóstico. RESULTADOS: Incluídos 294 indivíduos, 84% apresentavam AOS, sendo que em 28,8% a OAS era ligeira, 34,8% moderada e 36,4% grave. USANDO A ESCALA NOSAS PARA PREVISÃO DE AOS, AOS MODERADA A GRAVE E AOS GRAVE, A ÁREA ROC FOI: 0,770 (IC95%: 0,703-0,837), p<0,001, sensibilidade de 57,5% e especificidade de 83,0% para a pontuação 12); 0,746 (IC95%: 0,691- 0,802), p<0,001, sensibilidade de 68,2% e especificidade de 75,4% para a pontuação 13); 0,686 (IC95%: 0,622-0,749), p<0,001, sensibilidade de 71,1% e especificidade de 58,3% para a pontuação 13), respectivamente. USANDO A ESCALA STOP-BANG PARA A PREVISÃO DE AOS, AOS MODERADA A GRAVE E AOS GRAVE, A ÁREA ROC FOI: 0,862 (IC95%: 0,808-0,916), p<0,001, sensibilidade de 68,4% e especificidade de 85,1% para pontuação 5); 0,813 (IC95%: 0,756-0,861), p<0,001, sensibilidade de 77,3% e especificidade de 66,1% para a pontuação 5); 0,787 (IC95%: 0,732-0,841), p<0,001, sensibilidade de 70,0% e especificidade de 79,9% para a pontuação 6), respectivamente. CONCLUSÕES: A área ROC foi consistentemente alta para as duas escalas, confirmando a capacidade diagnóstica dos questionários NoSAS e Stop-Bang para todos os graus de gravidade de AOS. Assim, os nossos resultados sugerem que esses questionários podem ser um importante instrumento para rastreio e estratificação de doentes no diagnóstico de AOS. Globalmente, a capacidade de diagnóstico do Stop-Bang foi superior à do NoSAS.
