Active clinical trials for "Sleep Apnea, Obstructive"

Persistent obstructive sleep apnea (OSA) is common in people treated with mandibular advancement device (MAD) or hypoglossal nerve stimulation (HGNS). For most patients, these treatments are the last line of defense. If MAD or HGNS do not work, then patients are left to suffer the consequences of undertreated OSA. In this study, the investigators want to test the addition of a drug treatment to their regimen. Endotypes will be targeted pharmacologically with one of the following drugs: acetazolamide for a high loop gain, atomoxetine-plus-eszopiclone for poor pharyngeal muscle compensation, or trazodone for a low arousal threshold. This aim is expected to provide treatment strategies for rescuing non-responders to MAD or HGNS therapy.

Drug-induced sleep endoscopy (DISE) used as diagnostic tool but not yet as a therapeutic procedures to manage the upper airway of snorers and obstructive sleep apnea patients in conditions that mimic natural sleep, there are many aspects that need to be standardized in order to obtain reliable and reproducible information result in cryotherapy at sites of vibration as origin of snoring and site of collapse.

This is a prospective interventional study to better understand i) the prevalence of Obstructive Sleep Apnea (OSA) in Heart Failure with preserved Ejection Fraction (HFpEF), ii) its hemodynamic correlates, and iii) the impact of intervention with Continuous Positive Airway Pressure (CPAP) on quality of life.

Obstructive Sleep Apnea is a common medical condition in children. Diagnosis is based on polysomnography . We conducted an open prospective non randomised clinical trial to assess the efficacy of a new medical device called SUNRISE.

Obstructive Sleep apnea (OSA) is a common and underdiagnosed condition in obese pregnant women with serious and life-threatening complications to the mother and baby. The investiators propose that a non-invasive method may be used to detect patients at risk of OSA, giving these women access to the necessary treatment to treat this condition. The method is a estimation of body water, which has been shown to be linked to OSA in the non-pregnant population. Body water is estimated by applying surface electrodes to a participant who is lying down by measuring bioimpedance through body tissues by applying a tiny current between the electrodes. The electrical stimulation is not felt by the participant and has no negative effects on mother or baby.

Long term, prospective study of continuous positive airway pressure treatment influence on cognitive functions in patients with obstructive sleep apnea syndrome.

Obstructive sleep apnea (OSA) is a highly prevalent breathing problem that occurs during sleep. OSA have been associated with the obesity epidemic in developing countries; additionally, high OSA prevalence rates are present in populations with cardiovascular and metabolic disorders. Two OSA treatments are currently available, oral appliance (OA) therapy and continuous positive airway pressure (CPAP). OAs are an underutilized non-surgical treatment and few studies have analyzed their long-term effectiveness for patients with OSA. The purpose of this study is to assess the long-term effectiveness of OA therapy in patients with OSA and to explore any changes on cardiovascular related morbidity and mortality related to this therapy.

The purpose of this study is to determine whether early diagnosis of OSA and initiation of and adherence to CPAP therapy in patients hospitalized for chronic obstructive pulmonary disease reduce 30-day hospital readmission rates.

Sleep-disordered breathing (SDB) is prevalent in children and adolescents and untreated SDB impacts key indicators of physical and psychosocial health. Positive airway pressure (PAP) therapy is highly effective for the treatment of SDB and is associated with favorable clinical outcomes but is limited by poor adherence. Emerging literature in adults suggests that intolerance to PAP therapy may be related to coexisting insomnia. However, the presence of insomnia in children with known SDB as well as its impact on PAP adherence have not been explored. This proposal will explore the association of coexisting insomnia on PAP adherence in children with SDB using a cross-sectional study design. The investigators will assess the association between insomnia and PAP therapy adherence, measured as the mean minutes of nightly PAP usage over 6 months of use on objective downloads.

Obstructive sleep apnea (OSA) is independently associated with cardiovascular diseases, including myocardial infarction and stroke. OSA may promote atherosclerosis risk factors such as hypertension, diabetes and dyslipidemia and may have direct proatherogenic effects on the vascular wall. A growing number of studies have recently focused on the role of microparticles (MPs) in the atherogenic process. Case-control studies have shown that platelet-, endothelial- and leukocyte-derived MP levels are increased in OSA and that leukocyte-derived MP are released during the night in OSA. Furthermore, experimental evidence shows that MPs from OSA patients induce endothelial dysfunction. The objective of this prospective study is to evaluate the impact of increased levels of leukocyte derived MPs on the cardiovascular outcomes in patients with prevalent cardiovascular diseases investigated for OSA.
