Active clinical trials for "Apnea"

This study will be conducted to determine whether lemborexant as compared to placebo decreases the peripheral oxygen saturation during total sleep time in healthy adult and elderly participants after a single dose of treatment and to determine whether it increases the apnea-hypopnea index after single and multiple doses of treatment in adult and elderly participants with mild obstructive sleep apnea (OSA).

Introduction: Obstructive Sleep Apnea (OSA) is the most common form of sleep disordered breathing. Patients who arrive at the dental office with a diagnosis of OSA are often treated with a mandibular advancement device (MAD). A biomimetic oral appliance therapy (BOAT), offers an alternative non-surgical method, which can putatively resolve OSA by combined maxilla-mandibular correction, and addressing craniofacial deficiencies. The aim: To determine whether maxilla-mandibular correction changes induced by BOAT produce a more favorable upper airway, which might result in a reduction in the severity of OSA. Protocol: Adults who underwent an overnight sleep study and were diagnosed by a sleep specialist physician will be potential subjects for the current study. The BQ and EES will be recorded pre- and post- BOAT treatment. Subjects with mild to moderate OSA will have 2 months follow up visits and a final overnight sleep study to measure apnea-hypopnea index (AHI). The subjects will be asked to wear the appliance for 10-12 hours/day and at night. Findings will be analyzed statistically using paired t-tests.

The purpose of this research is to assess how well people with mild obstructive sleep apnea (OSA) adhere to the eXciteOSA device and specifically examine whether adherence of the device is different with low versus high electrical stimulation. In addition, this research study will assess how well the device affects mild sleep apnea and if it improves sleepiness and quality of life.

Previous studies have shown that contractions of the jaw-closing masseter muscle (MAS) often occur shortly after respiratory events during sleep in obstructive sleep apnea (OSA) patients. Although it has been hypothesized that such non-specific motor activations may contribute to restoration of a compromised upper airway during respiratory events, proper physiological understanding of MAS contractions in patients with OSA is lacking. MAS contractions are usually associated with the termination of respiratory events, but these contractions do not always occur after respiratory events. Therefore, the above-stated hypothesis that "non-specific motor activations of the jaw-closing masseter muscle (MAS) may contribute to restoration of a compromised upper airway during respiratory events" is not accepted yet. Further, Kato et al. concluded from a recent study that MAS contraction is an orofacial manifestation of a general motor reaction to arousal occurring during sleep in OSA patients. This suggests that MAS contraction after a respiratory event is dependent on the arousal response rather than on the respiratory events per se.

The purpose of this study is to investigate the effect of renal transplantation on fluid overload and its consequence on the severity of obstructive sleep apnea, in patients with end stage chronic kidney disease. It aims further to investigate the relationship between overhydration, nocturnal rostral fluid shift and the severity of sleep apnea.

The purpose of this study is to find out whether taking eszopiclone (Lunesta) changes the breathing effort required to briefly wake people with obstructive sleep apnea from sleep (respiratory arousal threshold). We would like to see if taking eszopiclone can reduce the severity of obstructive sleep apnea in some people (those that have a low respiratory arousal threshold; i.e. wake up easily to respiratory stimuli).

The purpose of this research is to find out how a nasal spray (fluticasone furoate), sometimes given to children with obstructive sleep apnea syndrome (OSAS), works on certain cells within a child's adenoids. We hypothesize that intranasal steroids lead to an upregulation of T regulatory cells in the adenoid tissues of children with OSAS. This will result in a local reduction in inflammation and edema explaining the improvement in OSAS.

The purpose of this study is to assess the efficacy of Eszopiclone in improving short and intermediate-term compliance with continuous positive airway pressure (CPAP) in patients newly diagnosed with obstructive sleep apnea (OSA).

Context: Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular morbidity. Recurrent episodes of occlusion of upper airways during sleep result in hormonal changes that may predispose to high cardiovascular risk.These risks can rapidly be reduced by effective nasal continuous positive airway pressure (nCPAP) therapy Objective: To evaluate hypothalamic pituitary adrenal axis, insulin resistance, blood pressure values and adipokines in severe obese patients with and without OSAS and to determine if continuous positive airway pressure therapy (nCPAP) influenced responses.

The purpose of this study is to compare the levels of 8-isoprostane and other oxidative stress biomarkers in plasma and condensed exhaled air between patients with SAHS and cardiovascular complications, patients with SAHS without cardiovascular complications and control subjects. To evaluate the effect of three months of treatment with CPAP on the oxidative stress biomarkers.
