BACKGROUND: Both short sleep duration and sleep-disordered breathing (SDB) are associated with poor neurocognitive development. However, the co-contributions of short sleep duration and SDB on neurodevelopment in pre-school children are relatively unknown. METHODS: We assessed both sleep duration and SDB by quarterly questionnaire from three months to two years of age among Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort participants. Group-based modeling determined trajectories of total, daytime, and nighttime sleep duration and SDB...

BACKGROUND: Pediatric adenotonsillectomies are common and carry known risks of potentially severe complications. Complications that require a revisit, to either the emergency department or hospital readmission, increase costs and may be tied to lower reimbursements by federal programs. In 2011 and 2012, recommendations by pediatric and surgical organizations regarding selection of candidates for ambulatory procedures were issued. We hypothesized that guideline-associated changes in practice patterns would lower the odds of revisits...

Sleep disturbances, as well as sleep-wake rhythm disturbances, are typical symptoms of Alzheimer's disease (AD) that may precede the other clinical signs of this neurodegenerative disease. Here, we describe clinical features of sleep disorders in AD and the relation between sleep disorders and both cognitive impairment and poor prognosis of the disease. There are difficulties of the diagnosis of sleep disorders based on sleep questionnaires, polysomnography or actigraphy in the AD patients. Typical disturbances of the neurophysiological sleep architecture in the course of the AD include deep sleep and paradoxical sleep deprivation...

BACKGROUND: Excessive daytime sleepiness (EDS) is a significant public health concern, with sleep-disordered breathing (SDB) being a common cause. However, their precise relationship in patients with cardiovascular disease (CVD) is unclear. Furthermore, whether comorbid psychological disorders could contribute to EDS remains unknown. We aimed to assess the prevalence of EDS and its related factors, including SDB and depression, in patients with CVD.Methods and Results:We analyzed data from 1,571 patients admitted for various CVDs in a single university hospital (median age, 67 [56-76] years; 29...

Obstructive sleep apnea (OSA) is a common disorder characterized by episodic obstruction to breathing due to upper airway collapse during sleep. Because of the episodic airway obstruction, intermittently low O2 (hypoxia) and high CO2 (hypercapnia) ensue. OSA has been associated with adverse cardiovascular and metabolic outcomes, although data regarding potential causal pathways are still evolving. As changes in inspired O2 and CO2 can affect the ecology of the gut microbiota and the microbiota has been shown to contribute to various cardiometabolic disorders, we hypothesized that OSA alters the gut ecosystem, which, in turn, exacerbates the downstream physiological consequences...

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is associated with significant morbidity. We sought to present an updated systematic review of the literature on the accuracy of screening questionnaires for OSA against polysomnography (PSG) as the reference test. Using the main databases (including Medline, Cochrane Database of Systematic Reviews and Scopus) we used a combination of relevant keywords to filter studies published between January 2010 and April 2017. Population-based studies evaluating the accuracy of screening questionnaires for OSA against PSG were included in the review...

Background: Due to the high prevalence in pregnant women and potential association with pregnancy complications or perinatal outcomes, sleep-disordered breathing (SDB) has become an increasing concern. Methods: Pubmed and Embase were retrieved from inception until 2017 to conduct a meta-analysis to explore the association of SDB and several outcomes during gestation. A stratified analysis differentiated by the type of SDB [snoring alone/obstructive sleep apnea (OSA)] was also performed...

BACKGROUND: Obesity and anthropometric measurements predict more severe sleep-disordered breathing (SDB) in children, and are associated with cardiovascular risk factors in children without SDB. We aimed to investigate whether anthropometric measurements predicted autonomic control in children with SDB. We hypothesised that anthropometric measures would be significant predictors of decreased heart rate variability. METHODS: Children (3-17 years) with SDB (n = 298) and non-snoring controls (n = 126) underwent polysomnography...

BACKGROUND: Sleep-disordered-breathing (SDB), which is characterized by chronic intermittent hypoxia (IH) and sleep fragmentation (SF), is a prevalent condition that promotes metabolic dysfunction, particularly among patients suffering from obstructive hypoventilation syndrome (OHS). Exosomes are generated ubiquitously, are readily present in the circulation, and their cargo may exert substantial functional cellular alterations in both physiological and pathological conditions. However, the effects of plasma exosomes on adipocyte metabolism in patients with OHS or in mice subjected to IH or SF mimicking SDB are unclear...

Patients with cerebral palsy (CP), especially those at the severe end of the spectrum (Gross Motor Function Classification System levels IV-V equivalent), frequently suffer from sleep disturbance and sleep-disordered breathing (SDB). Non-invasive ventilation (NIV) is increasingly used in this patient group, albeit with little published evidence of its effectiveness in CP. This article aims to review the current evidence in the use of NIV in children with CP, highlighting areas of uncertainties, as well as the balance of potential risks, challenges and benefits...

As seen in this CME online activity (available at http://journal.cme.chestnet.org/sv-sleep-disorder), central sleep apnea (CSA) is associated with increased mortality in patients with heart failure (HF), and it has been thought that treatment of CSA may improve underlying HF. Positive airway pressure therapy, specifically auto-servoventilation (ASV), can not only suppress abnormal breathing patterns but has been reported to improve cardiac function in HF patients with CSA. In patients with HF and with CSA unsuppressed with CPAP, newer ASV use has been associated with significant CSA improvement; in addition, several studies have reported efficacy of ASV in the treatment of underlying cardiac dysfunction in HF patients with CSA...

Synchronization of molecular, metabolic, and cardiovascular circadian oscillations is fundamental to human health. Sleep-disordered breathing, which disrupts such temporal congruence, elicits hemodynamic, autonomic, chemical, and inflammatory disturbances with acute and long-term consequences for heart, brain, and circulatory and metabolic function. Sleep apnea afflicts a substantial proportion of adult men and women but is more prevalent in those with established cardiovascular diseases and especially fluid-retaining states...

BACKGROUND: Sleep-related breathing disorders seriously impair well-being and increase the risk for relevant somatic and psychiatric disorders. Moreover, risk factors for sleep-related breathing disorders are highly prevalent in psychiatric patients. The aim of this study was for the first time in Germany to study the prevalence of obstructive sleep apnea syndrome (OSAS) as the most common form of sleep-related breathing disorder in patients with psychiatric disorders. METHODS: In 10 psychiatric hospitals in Germany and 1 hospital in Switzerland, a total of 249 inpatients underwent an 8‑channel sleep polygraphy to investigate the prevalence of sleep apnea in this group of patients...

Obstructive sleep apnoea (OSA) affects approximately 4% of men and 2% of women in the middle ages but many of these patients are not diagnosed or treated. Cardiovascular and cerebrovascular morbidity and mortality are associated with sleep apnoea. This causal link has been confirmed in recent years on the basis of epidemiological, experimental and therapeutic data. The prevalence in the general population and the impact on the genesis and evolution of systemic and pulmonary arterial hypertension, of cardiac rhythm disorders, of coronary artery disease, of heart failure and of strokes should encourage clinicians to early diagnose and treat sleep disordered breathing and, if possible, to prevent them...

OBJECTIVE: Childhood sleep-disordered breathing (SDB) symptoms may comprise multiple phenotypes depending on craniofacial anatomy, tonsil and adenoid growth, body habitus, and rhinitis symptoms. The primary objective of this study is to identify and characterize the different SDB phenotypes to two years of age. METHODS: Data from 770 infants in the Edmonton sub-cohort of the Canadian Healthy Infant Longitudinal Study (CHILD) were analyzed to identify SDB phenotypes based on age of onset and duration of symptoms...

Central sleep apnea is characterized by frequent cessation of breathing during sleep, resulting in repetitive episodes of insufficient ventilation and abnormalities of acid-base balance. It may be primary or secondary, and it is uncommon in children, with limited data for this population. We present here the case of a five-year-old girl, known to have thoracolumbar myelomeningocele (for which she underwent a surgical procedure in infancy), secondary hydrocephalus (with a ventriculoperitoneal shunt) and flaccid paralysis, who was admitted in our hospital with prolonged fever syndrome, productive cough, severe dyspnea and perioral cyanosis...

Objective: To examine whether the relationship between the metabolic syndrome (MetS) and various sleep parameters [sleep duration, symptoms of sleep-disordered breathing (SDB), and sleep disturbances] varies by age. Methods: Waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting glucose were used to determine MetS status in a cohort ( N  = 19,691) of middle-aged (aged 45-64 years) and older (aged ≥65 years) subjects...

The electrocardiogram-based cardiopulmonary coupling (CPC) technique may be used to track sleep instabilities. With progressing age, maturational changes during childhood and adolescence affect sleep. The objective was to assess developmental changes in sleep instabilities in a natural setting. ECGs during nighttime sleep on regular school days were recorded from 363 subjects aged 4 to 22 years (204 females). The estimated total sleep time (ETST) decreased from 598 to 445 min during childhood and adolescence...

BACKGROUND: Drug induced sleep endoscopy (DISE) is hoped to identify reasons of failure of adenotonsillectomy (AT) in treating pediatric sleep disordered breathing (SDB). Maxillomandibular disproportion has been studied as another association which may explain alternative pathogenesis of SDB. We aimed to explore the relation between the size of the gonial angle and inclination of the epiglottis measured from cone beam CT (CBCT) and tongue base collapse based on DISE in children with SDB...

OBJECTIVES: A number of reports exist regarding the use of continuous positive airway pressure (CPAP) to manage obstructive sleep apnoea (OSA) in children, which we term 'conventional CPAP'. In contrast, there are few reports of home CPAP use for other indications, which we have grouped under the term 'cardiopulmonary'. The aims of this study were to (1) document cardiopulmonary indications for CPAP use in a cohort of infants and children, and (2) evaluate its effectiveness in this group...
