Active clinical trials for "Sleep Apnea Syndromes"

This study will include patients who have major surgery and are at risk for or have been diagnosed with sleep apnea. The patients will be monitored the night after surgery for repeating episodes of reduced breathing and oxygen levels. The study will determine if episodes of decreased breathing are reflected in the oxygen monitor.

The study is to examine the relationship between sleep apnea and neurocognitive behaviors in children with cleft lip/palate. Describe the incidence and severity of obstructive sleep apnea in an unselected population of grade school aged children with surgically repaired cleft palate. A. Is the incidence of OSA higher in children with cleft palate than age matched historical control groups? B. Are nighttime symptoms an adequate screening tool to exclude the diagnosis of OSA in children with surgically repaired cleft palate? Describe the velopharyngeal closure patterns during speech in an unselected population of grade school aged children with surgically repaired cleft palate. Describe the neurobehavioral phenotype of an unselected population of grade school aged children with surgically repaired cleft palate.

To assess the effects of weight loss on sleep disordered breathing in obese, Type 2 diabetics with obstructive sleep apnea.

The purpose of this study is to estimated prevalence of obstructive sleep apnea (OSA) in 4-8 year old children. To date, most studies estimating prevalence of sleep apnea in young children are based on utilizing subjective questionnaires. The few studies that have utilized objective sleep measures have tested only those children suspected of sleep apnea based on subjective questionnaires, finding prevalence in the range of 1-13%. Untreated OSA is associated with significant morbidities in children, affecting their behavior, cognitive development, cardiovascular-and cardio metabolic health, endocrine and immune function. Better understanding of prevalence of sleep apnea in young children should be beneficial. This study will help to understand the prevalence of sleep apnea in each age-group of children 4-8 years of age and whether certain groups, such as children with obesity or asthma have higher prevalence and/or more severe disease. The primary objective of this study is to get better understanding of prevalence and severity of sleep apnea in young children using objective sleep measures for all participants.

Fibromyalgia Syndrome (FMS) is a chronic disease that lasts for at least three months and is characterized by various symptoms such as tender points, widespread pain in the musculoskeletal system, sleep disturbance and fatigue. Obstructive sleep apnea (OSAS) is a disease characterized by repeated upper airway obstruction during sleep. Sleep disorders negatively affect the lives of individuals. The prevalence of OSAS is between 1-5% in studies and it is more common in men than in women. Fatigue, anxiety, depression and sleep disturbance are also common in patients with fibromyalgia. Likewise, the presence of symptoms such as musculoskeletal pain in patients with OSAS suggests that these two diseases may be related to each other. We planned this study to show the relationship between OSAS and fibromyalgia (FM).

Obstructive sleep apnea (OSA) and hypertension are closely associated diseases. Here we characterized the differences in the gut microbiome which is affected by the two diseases, when the two diseases coexist or are present alone. Fifty-two consecutive patients who underwent polysomnography (PSG) were enrolled and divided into four groups: without OSA or hypertension (OSA0HT0), OSA without hypertension (OSA1HT0), hypertension without OSA (OSA0HT1), and with OSA and hypertension (OSA1HT1). Fecal specimens were collected for 16S rRNA sequencing and the characteristics of community richness, diversity, and composition of the gut microbiome and their relationship with disease were analyzed using bioinformatics methods.

Obstructive sleep apnea syndrome (OSAS) is a sleep-disordered breathing characterized by the occurrence of repeated upper airway obstructions leading to airflow reduction (hypopnea) or cessation (apnea). The apnea-hypopnea index (AHI) is the number of apneas and hypopneas per hour of sleep. OSA patients often report cognitive complaints. About 25% of the elderly population is affected by this syndrome with a drastic increase of this rate among dementia patients. OSAS is considered to be an important risk factor for the development of hypertension, heart disease and stroke.

The aim of this study was to retrospectively evaluate the influence of Tobacco Smoking on the development of Obstructive Sleep Apnea (OSA).

The study aims to develop and test a user-friendly, accessible approach to sleep assessment which can function as an initial "triage" of targeted sleep conditions, such as insomnia, insufficient sleep syndrome, sleep apnea syndromes/snoring, and circadian sleep/wake disorders, within the clinical and community population. Specifically, this study will test the validity and reliability of a self-rated, digitized, and cost-effective diagnostic measure with sufficient sensitivity to accurately assess/diagnose common sleep conditions and/or risk for these conditions. Such an approach, would allow for faster assessment of common sleep conditions and disorders, and provide clinical knowledge to the individual, the physician, and if required insurance companies, as to those persons who need more immediate attention or treatment for their sleep condition.

This study investigates the differences between subjects with and without periodontitis in: the prevalence of (pre)diabetes mellitus, the risk of atherosclerotic cardiovascular disease, the prevalence of metabolic syndrome and the risk of obstructive sleep apnea syndrome.
