Sicheng Wu, Shuqi Chen, Yanfang Zhao, Xiuqiang Ma, Rui Wang, Jia He
Background/Aims: Several studies have demonstrated that sleep problems are associated with functional gastrointestinal disorders (FGIDs), such as irritable bowel syndrome (IBS), and functional dyspepsia etc, but the relationship between excessive daytime sleepiness (EDS) and FGIDs has not been systematically studied in general population. This study aimed to explore the relationship between EDS and specific types of FGIDs and the effect of the number of FGIDs on EDS. Methods: A sample of 3600 individuals (aged 18-80 years) was selected from 5 regions in China using a randomized stratified multi-stage sampling method...

Resistant hypertension is defined as blood pressure that remains above 140/90 mmHg in spite of the concurrent use of three antihypertensive agents of different classes at optimal dosing, of which one should be a diuretic. Accordingly, it is not synonymous with uncontrolled hypertension. Among a variety of risk factors, obstructive sleep apnea (OSA), which is a common type of sleep-disordered breathing, has been recognized a well-established risk factor for resistant hypertension. Indeed, both European and American guidelines for the management of arterial hypertension stated that OSA is a modifiable cause of resistant hypertension...

STUDY OBJECTIVES: Objective and subjective measures of excessive daytime sleepiness (EDS) are only weakly associated. No study, however, has examined whether these two measures of EDS differ in terms of underlying mechanisms and prognostic value. Pro-inflammatory cytokines, i.e., interleukin-6 (IL-6) appear to promote sleepiness/fatigue, while the stress hormone cortisol promotes vigilance. We hypothesized that objective sleepiness is associated with increased levels of IL-6 and decreased levels of cortisol...

While several methods have been used to restrict the sleep of experimental animals, it is often unclear whether these different forms of sleep restriction have comparable effects on sleep-wake architecture or functional capacity. The present study compared four models of sleep restriction, using enforced wakefulness by rotation of cylindrical home cages over 11 h in male Wistar rats. These included an electroencephalographic-driven 'Biofeedback' method and three non-invasive methods where rotation was triggered according to a 'Constant', 'Decreasing' or random protocol based upon the 'Weibull' distribution fit to an archival Biofeedback dataset...

BACKGROUND: Poor sleep is common in patients with multiple sclerosis (MS). This study assessed the prevalence of poor sleep and investigated the potential impact factors that influence sleep quality of patients with MS. METHODS: A cross-sectional self-report survey of 231 patients with MS and 265 sex- and age-matched controls was conducted. Good sleepers and poor sleepers were separated by their global score on the Pittsburgh Sleep Quality Index (PSQI). Sociodemographic parameters, such as age, gender, and marital status, and clinical-demographic parameters, such as excessive daytime sleepiness (measured by the Epworth Sleepiness Scale), snoring, insomnia, obstructive sleep apnea, drugs, pain, depression, fatigue, and quality of life, were registered...

For the recent years, a special attention is given to the non-motor symptoms of Parkinson's disease, including sleep/wake disorders representing one of the leading symptoms. Daytime sleepiness occurs in 30-55% of patients depending on duration and stage of the disease, leading to severe maladjustment. This symptom seems to be multifactorial by nature and identification of it's causes could have a great importance for the therapy. The main factors of the development of daytime sleepiness in Parkinson's disease and key points of the pathogenesis of «primary» daytime sleepiness are discussed...

BACKGROUND: Hypersomnolence is common in depression, however longitudinal associations of excessive daytime sleepiness (EDS), long habitual sleep duration, and objective sleep propensity with depressive symptomatology are not well established. METHODS: Data from adults participating in the Wisconsin Sleep Cohort Study who had multiple assessments at 4-year intervals were utilized in analyses. Conditional (intrasubject) logistic regression estimated the likelihood of development of depression and three primary hypersomnolence measures: subjective EDS [Epworth Sleepiness Scale (ESS) >10], habitual sleep duration ≥9h/day, and increased physiological sleep propensity [multiple sleep latency test (MSLT) mean sleep latency <8min]...

BACKGROUND: Clinical presentation phenotypes of obstructive sleep apnoea (OSA) and their association with comorbidity as well as impact on adherence to continuous positive airway pressure (CPAP) treatment have not been established. METHODS: A prospective follow-up cohort of adult patients with OSA (apnoea-hypopnoea index (AHI) of ≥5/h) from 17 European countries and Israel (n = 6,555) was divided into four clinical presentation phenotypes based on daytime symptoms labelled as excessive daytime sleepiness ("EDS") and nocturnal sleep problems other than OSA (labelled as "insomnia"): 1) EDS (daytime+/nighttime-), 2) EDS/insomnia (daytime+/nighttime+), 3) non-EDS/non-insomnia (daytime-/nighttime-), 4) and insomnia (daytime-/nighttime+) phenotype...

The purpose of this study based on a cross-sectional internet survey was to investigate the relationship between risk of obstructive sleep apnea (OSA) and self-assessed oral health status. The participants, who comprised individuals registered with an online research company, were required to complete a self-reported questionnaire. Those answering in the affirmative to both of the following two questions were placed in the OSA-risk group, while those answering in the negative were assigned to the control group: 'Have other people noticed pauses in your breathing while you are sleeping?' and 'Do you feel excessively sleepy during the daytime?'...

OBJECTIVES: The Neurological Fatigue Index (NFI-MS) is the only known perceived fatigue scale to include questions that consider the contribution of sleep quality to symptoms of fatigue in people with multiple sclerosis (MS). However, the relationship between the NFI-MS and sleep quality measures is unknown. This study aimed to explore the relationship between the NFI-MS and self-reported and objective sleep quality. Understanding the relationship between perceived fatigue and sleep quality measures could encourage a wider use of the NFI-MS in research and clinical settings...
