Active clinical trials for "Sleep Apnea Syndromes"

The purpose of this research study is to learn more about the relationship between Obstructive Sleep Apnea (OSA) and Normal Tension Glaucoma (NTG). OSA is a nighttime disorder of the upper airway that causes an intermittent lack of oxygen while sleeping. NTG is a type of glaucoma that occurs despite the normal intraocular pressure levels, making its detection more difficult. Left untreated, irreversible optic nerve damage and extensive vision loss can result. Previous research has shown some evidence between OSA and the development of NTG. The investigators are researching whether undergoing treatment for OSA would help to improve the vascular health to the retina, and in effect, improve the early signs of visual dysfunction seen with diagnostic testing.

The aim of this study is to explore the role of diet/lifestyle intervention on Positive airway pressure (PAP) treatment adherence in patients with obstructive sleep apnea (OSA).Specifically, we evaluated the effects of a combination of PAP and weight-loss Mediterranean diet intervention on improving PAP adherence, Body mass index (ΒΜΙ), daytime symptoms, mainly sleepiness and arterial blood pressure measurements over the effect of standard care alone.

Use of mandibular advancement devices(MADs) in the treatment of Obstructive Sleep Apnea is established, however this is hampered by high costs, long wait times and non-assured success in the local Asian setting. There are few studies which look at the use of prefabricated thermoplastic mandibular devices with a titratable component and its efficacy. In addition, it is direct-to-consumer and an economical option, thus there may be a role in the use of such devices to better select patients who may benefit and are thinking of using MADs. The investigators aim to evaluate the effectiveness of the use of Prefabricated adjustable thermoplastic mandibular advancement devices(PAT-MADs)(MyTAP) in the treatment of OSA and its role for predicting treatment success in an Asian population.

This study evaluates the feasibility and effectiveness of an oropharyngeal exercise (O-PE) regimen in treating post-stroke obstructive sleep apnea, as an alternative therapy to continuous positive airway pressure (CPAP). Eligible patients will be randomized (1:1) to treatment using a pre-specified schedule of O-PEs vs. a sham control arm.

Obesity is the main risk factor for Obstructive Sleep Apnea (OSA). Nasal CPAP is the standard treatment for OSA, but since weight-loss programs are not usually offered to OSA patients, the root causes of their illness and its comorbidities are not treated. There is some evidence regarding improvements in OSA after weight reduction but whether weight reduction programs are cost-efficient has not as yet been addressed. OBJECTIVE: To determine whether an intensive weight-loss program, carried out in a project combining hospital and primary care levels, is cost-effective in the medium and long term for the treatment of obese patients with severe OSA undergoing CPAP treatment. More concretely, our objective is to demonstrate whether this program achieves sufficient improvement in OSA to allow a reduction <30/h in the apnea-hypopnea index in at least 25%, improving their metabolic profile and central obesity. METHOD: A prospective, randomized, controlled study. Control group: standard dietary recommendations. Intervention group: 0-3 months very low calorie diet, 15 days substituting three meals for low calorie shakes, from 15 to 120 days substituting 1 meal and from 120 days to 12 months on a low calorie diet while starting a progressive exercise program. Recommendations for good sleep habits will be given. The program will be carried out through group and individual sessions with the hospital dietician. After 3 months: group sessions with a nurse in the basic area. Group sessions led by hospital dietician. From 3 to 12 months: group sessions led by primary care nurse. MEASUREMENTS: At the beginning, at 3 and at 12 months: two-night home respiratory polygraph, actigraphy, anthropometric and blood analysis data including metabolic syndrome and inflammatory markers, and health related quality of life questionnaires. Direct and indirect costs of treatments, outpatient's consultations, incomes, emergency visits and patients' travel costs to medical centers.

The purpose of this study is to assess the safety and tolerability of multiple dose administration of gefapixant (MK-7264) in participants with moderate to severe obstructive sleep apnea (OSA). The primary hypothesis is that multiple dose administration of gefapixant (MK-7264) in participants with moderate to severe OSA reduces the Apnea Hypopnea Index (AHI) relative to placebo.

This investigation tested the hypothesis that children with obstructive sleep apnea have an increased pharmacodynamic sensitivity to the miotic and respiratory depressant effects of the prototypic μ-opioid agonist remifentanil.

In this prospective randomized cross-over trial, 3 different titration procedures will be compared: titration of the mandibular advancement device (MAD) in the home setting based on both the physical limits of the patient's mandibular protrusion and the resolution of subjective complaints, as currently often used in routine clinical practice; an overnight titration PSG using the remotely controlled mandibular positioner (RCMP) with stepwise mandibular protrusion until respiratory events are reduced and incremental protrusion of the mandible during DISE using the RCMP until upper airway collapse at all collapsible levels is eliminated. The aim of this study is to prospectively compare the target protrusion, as well as the treatment outcome in terms of treatment efficacy, of the 3 different titration protocols.

This study is conducted to investigate the effects of ACT-541468 on nighttime respiratory function in patients with mild to moderate obstructive sleep apnea

This study evaluates treatment effect of Cervical Collar (CC) in moderate obstructive sleep apnea.The investigators believe that stabilization of the neck by using a CC during sleep helps sustain airway patency. This would mean preventing collapse of airways during sleep. The study is a randomized, open, parallel-group intervention study. The two treatment groups are: A. Patients with moderate OSA are treated with lifestyle advice (n = 50) B. Patients with moderate OSA are treated with CC and lifestyle advice (n = 50).
