Background. Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from increased daytime sleepiness. The aim of this study was to identify potential predictors of subjective daytime sleepiness with special regard to sleep-related breathing disorder and nocturnal activity. Methods. COPD patients were recruited at the University Hospital Basel, Switzerland. COPD risk groups A-D were d...

INTRODUCTION The impact of Obstructive sleep apnea (OSA) in worsening outcomes is profound, especially in the presence of comorbid conditions. This study aimed to describe the proportion of patients at a high risk of OSA in our practice setting. METHODS The STOP BANG questionnaire and the Epworth Sleepiness scale were used to assess for OSA risk and excessive daytime sleepiness respectively. ...

In 1997 Wright and colleagues published a systematic review on the health effects of obstructive sleep apnoea syndrome (OSA) and the effectiveness of treatment with continuous positive airway pressure (CPAP). They concluded that there was limited evidence of increased mortality or morbidity in patients with OSA, and that the evidence linking the condition to cardiovascular risk factors and moto...

Detection of nocturnal hypoxaemia, defined as a mean arterial oxygen saturation below 90%, in normoxic or mildly hypoxic chronic obstructive pulmonary disease (COPD) patients seems clinically relevant, since this feature may precede pulmonary hypertension. Nocturnal studies are expensive and time-consuming procedures. The current study investigates to what extent it is possible to predict noctu...

AIM To explore the association of daytime sleepiness, sleep complaints and sleep habits with self-reported car crashes among public transport drivers. METHODS A cross-sectional descriptive study was carried out on male professional public drivers in two different cities using a validated, self-administered sleep questionnaire which comprised of symptoms suggesting sleep disorders, a subjectiv...

Background: Obstructive sleep apnoea syndrome (OSAS) affects an estimated 2–4% of the middle aged population. Meta-analyses of randomised controlled trials have shown that the severe presentation of the syndrome (apnoea hypopnoea index (AHI) .30/hour) is effectively treated with continuous positive airway pressure (CPAP). Until recently there have been insufficient data to determine whether CPA...

The purpose of this study was to describe the association between sleepiness, exercise, and physical function in older adults, testing the hypothesis that sleepiness predicts decreased exercise and impaired physical function in this population. We performed a secondary analysis of data from the National Sleep Foundation's Sleep in America Poll, comparing frequency of exercise and ability to per...

AIM In this study we investigated sleep and circadian rhythm, functioning and psychopathological symptoms in patients with schizophrenia. We looked for answers to the following questions: What percentage of patients with schizophrenia after a therapeutic process in the daily psychiatric ward suffers from insomnia and excessive daytime sleepiness? What factors influence the functioning of patien...

Excessive Daytime Sleepiness is a core symptom of narcolepsy and idiopathic hypersomnia, which impairs driving performance. Adequate treatment improves daytime alertness, but it unclear whether ...
