Active clinical trials for "Apnea"

Study objective: To assess the nocturnal changes in mechanosensitivity and chemosensitivity in hypertensive sleep apnea-hypopnea syndrome (SAHS) patients and in SAHS patients with isolated nocturnal hypertension. To value the continuous positive airway pressure (CPAP) effect on these parameters. Design: Controlled cross-over longitudinal study. Settings: Madrid metropolitan area. Patients: Day-night sustained hypertensive and isolated nocturnal hypertensive patients with SAHS without previous treatment. At least 30 patients are needed. Interventions: Patients will allocate in each treatment arm (CPAP vs. sham CPAP) during three months. Explorations will perform before and immediately after sleep at 0-, 3-, and 6-months of trial. Measurements: 24-h urinary catecholamine, local vascular factors, angiotensin and aldosterone levels. Diaphragmatic tension-time index, metabolic rate, hypoxic withdrawal test, and ventilatory and inspiratory neural drive responses to progressive isocapnic hypoxia.

Recent evidences from small studies show potential benefit of acupuncture in the treatment of obstructive sleep apnea (OSA). These studies did not evaluate the benefit of the treatment on the cardiovascular system. Primary end-point: To investigate the effects of acupuncture in improving OSA severity among hypertensive patients. Secondary end-point To investigate the effect of acupuncture in improving the quality of life and sleep assessed by the Short Form 36 (SF-36) questionnaire and Pittsburgh Questionaire (PSQI); To investigate the effect of acupuncture in blood pressure and arterial stiffness

This is a randomized control trial in people with diabetes and obstructive sleep apnea who will be randomly assigned for 3 months to PAP therapy along with healthy lifestyle and sleep education or healthy lifestyle and sleep education.

This is a prospective, multi-center, single arm, feasibility study to evaluate the safety and effectiveness of the ReVENT Sleep Apnea System for the treatment of Obstructive Sleep Apnea.

Prospective, randomized controlled trial. Pregnant women in early pregnancy will be randomized to either the Sleep Study + CPAP (Continuous Positive Airway Pressure Therapy) group or to a Standard Prenatal Care group. Subjects in the Sleep Study + CPAP group will complete a sleep study (WatchPAT-200, Itamar Medical, Inc.) and have CPAP initiated if the Apnea Hypopnea Index (AHI) ≥5 as indicated, in early and late pregnancy, whereas the other group will receive standard prenatal care. All subjects will complete a sleep study again between 8 to 12 weeks postpartum.

This investigation is designed to evaluate the performance (leak and comfort) as well as the participant's overall acceptance of the nasal pillows mask amongst Obstructive Sleep Apnea (OSA) participants. Also to assist in the development process it would be beneficial to get feedback from users on certain aspects of the design. The aim of this investigation is to get feedback on the first impressions (look and feel) from users of nasal pillows PAP therapy. A total number of 15 participants who currently use a nasal pillows mask will be recruited for the trial. Participants from previous NZ trials may be recruited into this trial with their consent. All the participants will be recruited from the Fisher & Paykel Healthcare Database of subjects with OSA (Ethics Reference NTY/08/06/064), Auckland District Health Board (ADHB) and New Zealand Respiratory and Sleep Institute (NZRSI). Participants will undergo an overnight polysomnography session at the Fisher & Paykel Healthcare sleep lab. The participant will use the trial device on their usual Continuous or Auto Positive Airway Pressure (CPAP/APAP) setting and device for the duration of the overnight in-lab study.

Obstructive sleep apnea syndrome (OSA) is a disease affecting 5-15% of population and 50-80% of type 2 diabetes mellitus (T2DM) and obese subjects. OSA causally contributes to the development of glucose intolerance and T2DM. The project is targeting the gap in providing effective treatment of metabolic impairments associated with OSA, particularly T2DM. In contrast to proved benefits of OSA treatment with CPAP (continuous positive airway pressure) on cardiovascular morbidity/mortality, studies on the impact of CPAP on diabetes control are disappointing. In fact, OSA-induced metabolic impairments might not be reversible with CPAP treatment, as investigators suggested recently. Clearly, the search for additional treatments, probably pharmacological, is warranted. Investigators hypothesize that elevated levels of free fatty acids (FFA), as detected in OSA patients, are linking OSA with the T2DM development. The aim of the study is to target adipose tissue and muscle dysfunction leading to elevated FFA and develop thus novel pharmacological treatments based on lipolysis inhibition and stimulation of FFA oxidation.

The objective of the study is to confirm the safety and efficacy in patients utilizing the aura6000 System for the treatment of Obstructive Sleep Apnea (OSA).

Aim: To assess if six months of treatment with CPAP associated with conventional drug therapy, contribute to improved glycemic control in patients with type 2 diabetes and sleep apnea-hypopnea syndrome SAHS)

Many individuals with Down syndrome (DS) have breathing problems during sleep. This is called obstructive sleep apnea syndrome (OSAS). OSAS is very common in individuals with Down syndrome because of the shape of their face and tongue and because of their low muscle tone. OSAS can cause a lot of health problems including behavioral and learning problems as well as heart problems. The purpose of this research study is to look at the effects of treating OSAS in individuals with Down syndrome with a machine called Continuous Positive Airway Pressure (CPAP). The investigators want to see if treatment of OSAS improves learning, behavior and heart problems.
