Effects of Inspiratory Muscles Strengthening Among Coronary Patients on the Sleep Apnea Obstructive...

Sleep ApneaObstructive1 more

Obstructive sleep apnea (OSA) syndrome affects up to 5% of the general population. The prevalence is multiplied by 13 in coronary artery disease (CAD) patients. Many studies have shown that OSA syndrome was the main risk factor for cardiovascular morbidity and mortality (RR = 9.1 [95%, 2.6 to 31.2]). If the value of treatment with Continuous Positive Airway Pressure (CPAP) in symptomatic CAD patients (daytime sleepiness and/or 2 clinical symptoms with Apnea Hypopnea Index (AHI) ≥ 20) appears to be established, treatment with CPAP in asymptomatic CAD patients (with AHI> 30) may be too demanding. Alternative treatments are rare and results are highly variable. Therefore, it would be interesting to suggest other treatment modalities with moderate coronary and/or minimally symptomatic OSA syndrome.

Effects of Compression Stockings on Obstructive Sleep Apnea in Patients Under Hemodialysis

Renal Failure Chronic Requiring DialysisObstructive Sleep Apnea

To study the effects of compression stockings on sleep apnea in hemodialysis patients with diagnosed obstructive sleep apnea. The rationale of this study consists in the fluid shift theory, which consists in the nocturnal rostral fluid shift from legs, which causes upper airways edema. The aim of this study is to evaluate if compression stockings could improve such nocturnal volume redistribution and, therefore, improve obstructive sleep apnea.

Auto-PAP for Pulmonary Hypertension Treatment in Decompensated HF Patients With Sleep Apnea.

Sleep ApneaObstructive3 more

The objective of the study is to evaluate the effect of continuous positive airway pressure (PAP) therapy on pulmonary arterial (PA) pressures in acute decompensated heart failure (HF) patients with obstructive sleep apnea (OSA). The study will also assess changes in functional parameters, biomarkers, and echocardiographic parameters.

Domiciliary Transcutaneous Electrical Stimulation in Obstructive Sleep Apnoea

Obstructive Sleep Apnea

The aim of this study is to assess the efficacy of transcutaneous electrical stimulation of the pharyngeal dilator muscles in patients with obstructive sleep apnoea in the community compared to usual care, and follow the patients for three months, as well as to assess compliance of non-invasive electrical stimulation of the upper airway dilator muscles in obstructive sleep apnoea patients over time and evaluate the control of symptoms and improvement in quality of life.

Management of Obstructive Sleep Apnea (OSA) in Children and Maxillary and Mandibular Development...

Obstructive Sleep Apnea Syndrome

Assessment of the association of maxillary expansion using a rapid palatal expansion, use of a mandibular advancement appliance (MGA™) and of a device allowing sleep in a semi-seated position (Yoobreath™) in patients with Obstructive Sleep Apnea (OAS). MGA™ and YooBreath™ constitute the Yookid system™.

Efficacy of a Novel MAD in OSA

Sleep ApneaObstructive6 more

Oral appliances (OA) have emerged as an alternative to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. The most commonly used OA reduces upper airway collapse by advancing the mandible (mandibular advancement devices, MAD). There is a strong evidence base demonstrating that MADs improve OSA in the majority of patients, including some with more severe disease. However, MADs are not efficacious for all, with approximately one-third of patients experiencing no therapeutic benefit. Patients often prefer MADs to gold-standard CPAP treatment. Head-to-head trials confirm CPAP is superior in reducing OSA parameters on polysomnography; however, this greater efficacy does not necessarily translate into better health outcomes in clinical practice. Comparable effectiveness of MADs and CPAP has been attributed to higher reported nightly use of MADs, suggesting that inferiority in reducing apnoeic events may be counteracted by greater treatment adherence. The MAD in study, called Bite-Velo Linguale (BVL), features a novel monobloc device including a tongue retainer, a suction cavity that maintains the tongue down onto the mouth floor in order to prevent it from raising towards the hard palate, and therefore increasing the retro lingual aerial space. Its design requires the presence of only four occlusal points, allowing for a direct anchorage onto the mandibular bone, thus reducing the risk for occlusal changes, tooth loosening and the development of an anterior cross bite, which represent some of the major long-term adverse effects of oral appliances. MADs are generally well tolerated, although short-term adverse effects during acclimatization are common. Long-term dental changes do occur, but these are for the most part subclinical and do not preclude continued use. The BVL in study features technological advances aimed at preventing long-term dental changes, as well as improving tolerability and easiness of use.

The Evaluation of a Full Face Mask Seal for the Treatment of Obstructive Sleep Apnea

Obstructive Sleep Apnea

The investigation is a prospective, randomized, single blinded, crossover study. The investigation is designed to evaluate the performance, comfort and ease of use of the F&P Trial Full Face Mask Seal amongst Obstructive Sleep Apnea (OSA) participants. A total number of 40-45 OSA participants will be recruited for the trial by the investigation site

CPAP Effect on Albuminuria in Patients With Diabetic Nephropathy and Obstructive Sleep Apnea

Diabetic NephropathySleep Apnea

Objectives: Main objective: To assess the effect of 12 months of CPAP treatment added to conventional drug treatment on the albuminuria in patients with diabetic nephropathy and obstructive sleep apnea (OSA). Secondary objectives: To evaluate the effect of CPAP treatment on the estimated glomerular filtration rate of patients with diabetic nephropathy and OSA; determine the additional longterm CPAP effect on glycemic control, insulin resistance, lipid profile, health-related quality of life and biomarkers of cardiac function, inflammation, oxidative stress, sympathetic tone and appetite-regulating hormones in patients with diabetic nephropathy and OSA; and to identify the subgroup of patients with diabetic nephropathy and OSA in which 12 months of treatment with CPAP achieve a more pronounced reduction in albuminuria. Methodology: Randomized, multicenter, non-blinded, parallel groups, conventional treatment-controlled trial of 12 months of duration. Subjects will randomize to conventional dietary and pharmacological treatment or conventional dietary and pharmacological treatment plus continuous positive airway pressure (CPAP). Study subjects: Subjects 18 to 80 years with overweight or obesity and a clinical diagnosis of diabetic nephropathy, increased urinary albumin/creatinine ratio of 30 mg/g and an estimated glomerular filtration rate >20 ml/min/1.73 m2, and treatment with stable doses of angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs) or anti-aldosterone drugs in the last four weeks. Efficacy variables: urinary albumin/creatinine ratio and estimated glomerular filtration rate; glycosylated hemoglobin (HbA1c); fasting glucose and insulin; homeostatic model assessment (HOMA) and QUICKI indices; total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides; Troponin I, proBNP, homocysteine and high-sensitivity C-reactive protein; systemic biomarkers (inflammation [IL-6, IL-8 and tumor necrosis factor-α], oxidative stress [8-isoprostane], endothelial damage [endothelin, VCAM-1 and ICAM-1], sympathetic activity [neuropeptide Y] and appetite-regulating hormones [leptin and adiponectin]) and clinical questionnaires: short form (SF)-12, EuroQoL and iPAQ.
