Filter by:ARCTIC-1 is a safety and dosing study to evaluate procedure tolerability in patients with clinically diagnosed moderate or severe OSA.
The main objective of this study is to evaluate the accuracy of the ANNE Sleep system for the diagnosis of obstructive sleep apnea (OSA) in adults
This is a single group, unblinded, prospective clinical study. This study seeks to understand patient diagnostic and treatment journey and positive airway pressure (PAP) therapy compliance for Verily Sleep Apnea (VSA) program/app users. Participants will enroll remotely and may undergo a home sleep test (HST). Upon confirmation of obstructive sleep apnea (OSA) and prescription of PAP therapy, the participant will begin using the VSA app to supplement PAP treatment. After 90 days of active participation, the participant will be given instructions for follow-up care, as indicated.
Investigators hypothesize that in patients with obstructive sleep apnea (OSA) the severity of periodontal disease is significantly higher compared to patients without OSA in every aspect, including PI, PD, CAL and BOP. The number of lost teeth is hypothesized to be also higher in patients with obstructive sleep apnea. Purpose: evaluation of periodontal status in patients with obstructive sleep apnea. An analytical cross-sectional study will be conducted at the Department of Therapeutic Dentistry of the Sechenov University, Moscow. Investigators are planning to recruit 100 patients: 1) patients with OSA confirmed by polysomnography -75 participants aged between 35 and 65; 2) patients without OSA -25 participants of a similar age. Patients with obstructive sleep apnea syndrome will be sub-divided into three sub-groups according to OSA severity: 2A group - patients with mild apnea severity; 2B group - patients with medium apnea severity; 2C group - patients with severe apnea. All participants will undergo a dental examination including the following parameters: plaque index (PI; Silness & Loe, 1964), bleeding on probing (BOP), and touch depth of the pocket (PD), the level of clinical attachment loss (CAL). Investigators will also evaluate the number of lost teeth.
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.
In this study the investigators will evaluate chronotype, food intake pattern, and cardiovascular risk markers of elder individuals with OSA, in use of CPAP, when submitted to two weeks of CPAP withdrawal.
The main objective of this study is to compare the change in the apnea-hypopnea index (AHI) in patients with mild to moderate sleep apnea without daytime sleepiness after 12 months of myofunctional therapy exercises with respect to the placebo group (the placebo group will be instructed in simulation exercises that do not alter the function or morphology of the upper airway)
Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults. Compared to the general population, OSA occurs more often in patients with coronary artery disease (CAD), with a reported prevalence of 38% to 65%. Emerging evidence indicates OSA initiates and exacerbates coronary atherosclerosis. Moreover, several observational studies indicate the presence of OSA was associated with higher rate of restenosis and repeat revascularization (mainly attributed non-culprit lesion revascularization) after percutaneous coronary intervention (PCI). OSA might initiate endothelial injury by repetitive bursts of sympathetic activity that occur with apneas and hypopneas. Moreover, untreated OSA reduces endothelial repair capacity. Whether OSA could exacerbate neointimal proliferation and plaque progression in the non-culprit lesion after drug-eluting stent (DES) implantation remains less studied. The investigators aimed to evaluate neointimal proliferation and strut coverage within stent segment as well as changes of plaque volume and morphology in the non-culprit lesion by optical coherence tomography (OCT) in patients with versus without OSA at 12-month follow-up.
Upper airway stimulation (UAS) is an effective surgical alternative for patients with obstructive sleep apnea (OSA) who fail continuous positive airway pressure (CPAP) therapy. This stimulation could lead to alterations in tongue strength and fatigability which could alter treatment outcome. The aim of the study is to investigate if UAS alters tongue strength and fatigability.
In previous review study, it was hypothesized that a comprehensive rehabilitation can combine both local pharyngeal muscle exercise and systemic cardiopulmonary rehabilitation for the OSA patients with oropharyngeal muscle dysfunction or ventilator drive instability. To develop a comprehensive rehabilitation model is of innovative care strategy in this study.
