Sleep Disordered Breathing and Pregnancy: Prevalence and Outcomes at Delivery
<p>Introduction<br /> Sleep Disordered Breathing (SDB) during pregnancy is associated with maternal and neonatal morbidity, and in-hospital mortality. A recent prevalence study using the Nationwide Inpatient Sample reported an obstructive sleep apnea (OSA) prevalence of 7.3 per 10,000 in 2013, a …

The natural history of sleep disordered breathing in 6-11 year old Caucasian and Hispanic children
Sleep disordered-breathing (SDB) including obstructive sleep apnea syndrome (OSAS) is increasingly recognized as an important cause of morbidity in children. Clinical symptoms of OSAS in children include snoring, nocturnal arousals, restlessness during sleep, enuresis, daytime sleepiness and …

Sleep Disorders and Kidney Transplant Outcomes: Findings From an 18-Year (1997-2015) Historical Cohort Study
… variables, any sleep disorder and any sleep-disordered breathing disorders, were defined through a diagnosis in a subject’s medical record. Transplant outcomes included: death with a functioning graft, graft survival time, and patient survival time after graft failure.</p> <p>Chi-square …

Use of Motion Artifact for the Detection of Respiratory Effort in Polysomnography
… effort is critical when diagnosing sleep disordered breathing. In this thesis work, the use of detecting respiratory effort by using the movement artifact found in the electromyographic (EMG) and electrocardiographic (ECG) recordings used in polysomnography was investigated. The resulting …

Chronic Hypoxia and Cardiovascular Dysfunction in Sleep Apnea Syndrome
… that chronic hypoxia associated with sleep-disordered breathing relates to abnormal Nitric Oxide (NO) production and vascular endothelial growth factor (VEGF) expression patterns that contribute to aberrancy of specific determinates of cardiovascular and cardiopulmonary function before, …

Investigation of heart rate variability during sleep apnea
… apnea and central sleep apnea in whom sleep-disordered breathing was diagnosed. In addition 6 control subjects were studied where sleep apnea was not expected. Spectral and wavelet analysis were used to investigate the heart rate variability from the sleep apnea subjects and control subjects. …

Extracting multi-person respiration from entangled RF signals
… signals that bounce off her body. The resulting breathing signal can be used to infer the person's sleep quality and stages; it also allows for monitoring sleep apnea and other sleep disordered breathing; all without any body contact. Unfortunately however past work fails when people are close to …

Obstructive sleep apnea and snoring in Icelandic children : the five-to-fifteen questionnaire and school performance
Sleep-disordered breathing (SDB), from reported snoring to obstructive sleep apnea (OSA), has been associated with emotional and behavioral problems in children, as well as academic decrements. This study examined reported snoring as well as objectively measured snoring and OSA in 112 children in …

EFFECTS OF DAPAGLIFLOZIN ON EXERCISE CAPACITY, RESPIRATORY FUNCTION, BIOMARKERS, SLEEP APNEA, AND LEFT VENTRICULAR REMODELING IN PATIENTS WITH HEART FAILURE: A PROSPECTIVE, SINGLE CENTER, NON RANDOMIZED STUDY
… protein-B (proSP-B), gas exchange, and sleep-disordered breathing. Evaluations were performed at baseline, 2–4 weeks, and after 6 months of treatment with dapagliflozin 10 mg/day. Results: Among 75 patients enrolled, 67 completed full follow-up. Dapagliflozin improved left ventricular ejection …

Data analysis in respiratory medicine : model selection and classification methods applied to clinical diagnostics
… II addresses the assessment of sleep-related breathing disorders by nocturnal monitoring of respiratory signals. Diagnosis of sleep-disordered breathing nowadays is carried out by polysomnography, i.e. by measurement of a multitude of neurologic and respiratory signals throughout the night in …

CARDIAC AUTONOMIC CONTROL DURING SLEEP IN PATIENTS WITH MULTIPLE SYSTEM ATROPHY: A PILOT STUDY ON THE IMPACT OF CPAP THERAPY
… aims to compare patients with and without sleep‐disordered breathing (SDB) and to assess the acute autonomic effects of CPAP therapy during the second night in patients with SDB. Methods We retrospectively analyzed v‐PSG recordings from MSA patients who underwent evaluation over two consecutive …

Distance to specialist medical care and diagnosis of obstructive sleep apnea in rural Saskatchewan
… sleep apnea (OSA) is the most common sleep-disordered breathing condition. Rural populations in Canada may be particularly at risk due to high reported levels of obesity, physical inactivity and other related risk factors. Patients with OSA symptoms are often not diagnosed clinically, which …

The relationship between obstructive sleep apnea syndrome and insomnia: implications for treatment
… sleep apnea syndrome (OSAS) is a sleep-disordered breathing condition that causes disrupted sleep. Although OSAS is most often associated with daytime hypersomnolence, a number of OSAS patients complain of insomnia, i.e., disorders of initiating or maintaining sleep. If the insomnia in …

Unstable Ventilatory Control During Sleep After High Spinal Cord Injury: The Contribution Of Chemosensitivity And Hypoventilation
… of Philosophy</p> <p>A high prevalence of sleep-disordered breathing (SDB) after spinal cord injury (SCI) has been reported in the literature; however, the underlying mechanisms are not well understood. My studies had 2 aims: 1) to determine the effect of the withdrawal of the wakefulness drive …

Insuline resistance and insuline sensibility in patients with obstructive sleep apnea

A Risk Stratification Model for Adult Patients with Obstructive Sleep Apnea: Development and Evaluation
Despite emerging evidence that obstructive sleep apnea (OSA) may cause cardio-metabolic disturbances independently of known risk factors, the strength and significance of this association remains unclear. This thesis is comprised of three studies assessing the long term-consequences of OSA, and …

The interrelationship between central sleep apnea and atrial fibrillation
INTRODUCTION: Research has consistently shown that sleep apnea is strongly associated with atrial fibrillation, with several lines of evidence demonstrating that this relationship is bidirectional and that each condition predisposes to and/or exacerbates the other. Many studies have suggested …

Modeling Post Stroke Respiratory Dysfunction, Apneas and Cognitive Decline
… <p>Our data suggests that stroke disrupts basal breathing rather than increasing chemoreceptor gain. Therefore, we predict treatments designed to stimulate breathing independent of chemoreceptor gain will improve respiratory instability, behavior, cognition and mortality. Systemic application of …
