Active clinical trials for "Sleep Apnea Syndromes"

To compare the number and function of regular T cell of patients with obstructive sleep apnea (OSA) versus that of age-, gender- and BMI (body mass index)-matched controls

This three-year project aims to Profile the differentially expressed metabolites in healthy patients with severe Obstructive sleep apnea (OSA) before and after six-month continuous positive airway pressure (CPAP) treatment Identify the candidate metabolites involved in biologic pathways attributing to OSA phenotyping and response to CPAP treatment Validate candidate metabolites in the intermittent-hypoxia model of peripheral monocytes

Obstructive sleep apnoea (OSA) is a common medical problem which, despite increasing awareness, remains under-diagnosed. There is a close association between OSA and obesity; 60-70% of patients diagnosed with OSA are either obese or overweight [1]. OSA is also very common among patients with type 2 diabetes. Type 2 Diabetes Mellitus (T2DM) has reached epidemic status in the Gulf region. OSA worsens insulin resistance and leads to weight gain through sleep disturbance [2]. Several mechanisms have been proposed for the associations of OSA with diabetes and obesity [3]. At present there is little available information regarding the prevalence of OSA in the UAE, the relationship with T2DM and obesity, and the impact of OSA on health outcomes in the Emirati population. This research will explore these relationships and inform public health decisions regarding diagnostic pathways, service provision and treatment protocols.

The purpose of this study is to develop adequate and satisfactory tools using reliable clinical and physical factors in predicting pediatric obstructive sleep apnea/hypopnea syndrome (OSAHS) and allow greater access to appropriate therapy in children.

Sleep disordered breathing (SDB) is a common condition affecting up to 9% of adults with serious neurocognitive, metabolic and cardiovascular consequences that has a significant impact on public health. Evidence indicates that the physiologic changes occurring during pregnancy, particularly during the third trimester, increase the risk of those women to develop SDB. As in the general population, SDB during pregnancy is more frequent among obese women. In the light of the increasing prevalence of obesity among females of reproductive age, SDB may thus have an increasingly significant impact on women's and children's health by contributing to the adverse maternal and fetal outcomes associated with maternal obesity. Only a limited amount of data is available on the consequences of maternal SDB during pregnancy. Even less information is available on the effect of maternal SDB on fetal growth and development. The current proposal is designed to specifically explore the effect of maternal SDB on fetal growth. It has been suggested that fetal growth as reflected in birth weight is a strong correlate for conditions occurring in the intrauterine environment with potential long lasting influence on a child's health. Our overall hypothesis is that the intermittent hypoxia, sleep fragmentation and the metabolic alterations associated with maternal SDB will affect fetal growth. Using a variety of methods and a multidisciplinary approach, we will explore the following objectives: 1) The effect of maternal SDB on fetal growth ; 2) To explore mechanisms that may underlay the effect of maternal SDB on fetal growth 3) To explore the long term (first 3 years of life) effect of maternal SDB on a child's growth. The results of this study will make an important contribution to the fields of women and children's health. It will provide better insight into the mechanisms by which disrupted maternal sleep affects fetal growth. We expect that the findings from our study will enable the defining of a new treatable clinical entity or syndrome: "the infant of the gestational SDB mother", for which early diagnosis and intervention might be of major importance to the newborn infant.

The purpose of this study is to explore long-term prognosis and to identify the predictors in Taiwanese OSA patients. Validation of the prediction model derived from NHIRD with the database of National Taiwan University Hospital (NTUH) sleep center is planed to determine the effects of different treatments on long-term prognosis.

RATIONALE of the project. Adults with Down syndrome (DS) present severe sleep disorders that are under recognized by caregivers. Aging in DS population increases the prevalence of both Obstructive Sleep Apnea (OSA) and Alzheimer´s disease (AD) dementia at much higher rates than in the general population. AD increases the risk of sleep disturbances and OSA, which in turn worsen cognitive performance and behavioral function. Our hypothesis is that adults with DS and AD dementia will present a higher prevalence of sleep disorders (sleep disruption, sleep circadian disorders and OSA) than in DS without dementia. There are no data evaluating nocturnal sleep in adults with DS with AD dementia. The main objective is to evaluate the prevalence of sleep disturbances in adult subjects with DS and AD dementia, by means of subjective and objectives sleep measures.

Women with PCOS and OSA, compared to women with PCOS only, have more severe clinical and biochemical features of PCOS and impaired QoL. This is an observational cross-sectional study in a secondary care PCOS clinic in the WISDEM Centre, University Hospital Coventry. The primary aim of this study is to examine the relationship between OSA and impaired QoL in women with PCOS. Study secondary outcomes are to examine the relationship between OSA and the clinical and biochemical features in women with PCOS.

While Drug Induced Sleep Endoscopy (DISE) in patients with obstructive sleep apnea syndrome (OSAS) apnea and hypopnea occur. Because of the induced phases of apnea in a controlled setting it is possible to evaluate the related pathophysiology of apnea. We plan to correlate the Patient State Index (PSI) and other physiologic parameters with phases of apnea and hypopnea.

The primary aim of this study is to research the effect of intubation without muscle relaxant on post-operative recovery conditions in patients with OSAS (obstructive sleep apnea syndrome). Our secondary aim is to research the hemodynamic parameters in intraoperative period and complications such as sore throat and laryngospasm voice limitation in the postoperative period.
