While chronic systemic inflammation in obstructive sleep apnea (OSA) has been traditionally considered a consequence of intermittent hypoxia, several treatment studies targeting inflammation suggest that this process may precede the development of the disorder. A recent cross-sectional study in the Penn State Child Cohort (PSCC) revealed that inflammation largely mediates the association between visceral adiposity and OSA in adolescence. The purpose of this study was to examine for the first time whether, longitudinally, inflammation precedes OSA during this developmental period...

OBJECTIVE: Patients with heart failure (HF) and sleep disordered breathing (SDB) are typically not sleepy, unlike patients without heart failure. Previous work in HF patients with obstructive SDB suggested that sleepiness was associated with a reduction in daytime activity. The consequences of predominately central SDB on sleepiness in HF are less well understood. The aim of this study was to test the hypothesis that subjective sleepiness is associated with reduced daytime activity in HF patients with central SDB, compared to those without SDB...

OBJECTIVE: Obstructive Sleep Apnea (OSA) has been associated with both subclinical and accelerated atherosclerosis; however, it still remains unknown whether this association is unique or is mediated by the higher burden of co-existing cardio-metabolic disorders frequently seen in patients with OSA. PATIENTS AND METHODS: A total of 40 subjects without clinically diagnosed cardiovascular disease (CVD) referred for polysomnography test were included in the study. Subjects with apnea/hypopnea index (AHI > 15/h) were classified as moderate/severe OSA...

The circadian system coordinates internal events in a daily schedule to make sure that the body systems are synchronized to environmental time and internal cues. One important behavioral aspect of the circadian system is the chronotype. It is usually assessed through subjective questionnaires, being the Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ) one of the most used. It classifies individuals into three major categories: morning, evening, and intermediate types. Recently, it has been hypothesized the existence of a fourth chronotype, the bimodal type, through an algorithm derived from the MEQ responses...

Sleep disorders are very common in advanced Parkinson's disease (PD) and have a significant negative impact on the quality of life of patients. Questionnaire-based studies suggest that sleep quality might improve following levodopa-carbidopa intestinal gel (LCIG) infusion. The objective of this study was to evaluate the impact of LCIG infusion and subsequent oral medication changes on polysomnography (PSG) and sleep symptoms in advanced PD patients. Eleven PD patients underwent PSG at baseline and after 3.8 ± 1...

BACKGROUND: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common chronic disorder which is followed by various complications. Calpain-10 belongs to a commonly expressed member of the Calpain-like cysteine protease family, which acts as risk marker for some diseases. The purpose of this study is to elucidate correlation between Calpain-10 single-nucleotide polymorphisms (SNPs) and the incidence of OSAHS followed by ischemic stroke (IS). METHODS: OSAHS patients were divided as OSAHS + IS, OSAHS, and control groups, respectively...

BACKGROUND: Screening instruments for obstructive sleep apnea (OSA), as used routinely to guide clinicians regarding patient referral for polysomnography (PSG), rely heavily on symptomatology. We sought to develop and validate a cerebrovascular disease-specific OSA prediction model less reliant on symptomatology, and to compare its performance with commonly used screening instruments within a population with ischemic stroke or transient ischemic attack (TIA). METHODS: Using data on demographic factors, anthropometric measurements, medical history, stroke severity, sleep questionnaires, and PSG from 2 independently derived, multisite, randomized trials that enrolled patients with stroke or TIA, we developed and validated a model to predict the presence of OSA (i...

Daytime sleepiness is a common symptom among hypertensive patients. The aim of this study was to determine subjective sleepiness assessed by Epworth Sleepiness Scale (ESS) and to asses sleep architecture in 304 patients with arterial hypertension. All patients underwent a standardized diagnostic overnight, polysomnography. The control group consisted of 67 normotensives. The hypertensive patients had a decreased sleep efficiency, mean and minimum oxygen saturation levels, and increased apnea/hypopnea index and oxygen desaturation index compared with normotensive patients...

OBJECTIVE: Children with Down syndrome (DS) are liable to develop obstructive sleep apnea (OSA) due to many anatomical airway abnormalities. The tonsils and adenoid occupy part of the airway space, and their removal may be helpful in relieving airway obstruction. The aim of this study was to assess the effectiveness of adenotonsillectomy in the treatment of OSA in those children. METHODS: Fifty DS children with difficult breathing were recruited, and they were subjected to polysomnographic examination (PSG)...

INTRODUCTION: Patients referred to tertiary care for multidisciplinary investigation of unexplained chronic fatigue are not seldom diagnosed with obstructive sleep apnoea (OSA). As standard treatment for OSA, continuous positive airway pressure (CPAP) has been shown to decrease daytime sleepiness in OSA patients. However, the effect on fatigue as major complaint in chronic fatigue patients without excessive daytime sleepiness, is not fully understood nor explored. CASE REPORT: A prospective cross-over trial using effective and sham CPAP treatment periods in patients with unexplained chronic fatigue and OSA was interrupted because of poor recruitment and retainment due to complex design issues...
