Filter by:Obstructive sleep apnea (OSA) is a common sleep disorders associated with excessive daytime sleepiness and cardiovascular disease. Continuous positive airway pressure (CPAP) therapy is an effective standard treatment and is widely prescribed for patients with OSA. Successful CPAP treatment has also been shown to improve cognitive, cardiovascular and metabolic function. Sustainable CPAP treatment would alleviate the substantial cost burden of health-related consequences of untreated OSA. However, the use of CPAP for such patients is disappointingly low and limits the effectiveness of treatment. Early CPAP education and follow up have shown to be very important in helping subjects to handle side-effects or problems associated with the use of CPAP. Good education program at the initial phase of using CPAP is essentially affected the acceptance and adherence of CPAP therapy. Good CPAP adherence is not only medically essential to patients' health but also economically importance to society by alleviating the substantial cost burden of health-related consequences. To the best of our knowledge, there is no randomized clinical trial (RCT) to prove the long-term efficacy of extended education program on improving continuous positive airway pressure use and its treatment outcomes. The primary purpose of this study is to assess the long-term efficacy of our on-going RCT which is an extended education program on improving CPAP compliance. The investigators hypothesize that the application of both MI technique and SCT-based extended education program at the initial phase of using CPAP also would enhance CPAP adherence even after one year of attending education class.
This is a randomized controlled study evaluating the impact of 2 months of oral appliance therapy on endothelial function in patients with severe obstructive sleep apnea syndrome intolerant to continuous positive airway pressure (CPAP) therapy.
The overall goal of this study is to determine the efficacy of a lifestyle intervention, consisting of a weight loss diet and exercise on sleep apnea in older adults. The investigators will conduct a 3-month intervention in men and women who are sedentary with suspected sleep apnea. The investigators hypothesize that the intervention will lead to marked improvements in sleep apnea severity and cardiovascular risk markers.
The purpose of the study is to evaluate if using the Acclimate feature at the beginning of Positive Airway Pressure (PAP) therapy results in patients using their PAP therapy at least as long as they would standard therapy. Additionally, the Acclimate feature will be evaluated with regard to patient comfort, ease of acceptance of PAP therapy, leak events, and respiratory events.
Assessment of the performance of the Salt Lake mask system acting as a patient interface in the provision of PAP therapy. This study will assess the suitability of this mask system in its current form for use.
Pain after tonsillectomy can be severe and last ten days. Various new surgical instruments have been developed over the years in an attempt to reduce postoperative pain with mixed results and increased costs; no single tonsillectomy technique is superior to the rest. Patients are discharged to home usually on the day of surgery and often suffer significant pain and nausea. Pain medication is often prescribed which can cause nausea, vomiting and constipation. Children in pain are reluctant to take in fluids and may require intravenous hydration at an emergency department. "Battlefield acupuncture " has been recently developed by the US Air Force and is now being used in Iraq and Afghanistan on wounded warriors suffering severe acute pain from trauma. This protocol consists of five acupuncture points on the outer ear. A recent study has demonstrated decreased pain and agitation in children undergoing ear tube insertion. Ear tube patients have mild discomfort compared to tonsillectomy patients and are able to attend school the next day. The investigators have been encouraged by the benefits of acupuncture during surgery for ear tube patients and also wounded warriors recovering from their injuries. These findings motivated us to see if acupuncture during tonsillectomy surgery would result in less pain and nausea.
The investigators performed a randomized, cross-over controlled clinical trial comparing 8 weeks of Continuous Positive Airway Pressure (CPAP) to 8 weeks of sham-CPAP in patients with moderate to severe Sleep Disordered Breathing (SDB) and impaired glucose tolerance. A rigorous assessment of metabolic responses to SDB treatment in this group is of great clinical significance because this sample is at high risk for developing diabetes. The paradigm shift of CPAP as a mode of prevention can affect clinical practice in the fields of both primary care and sleep medicine.
Obstructive sleep apnea syndrome (OSAS) is a common form of sleep-disordered breathing (SDB) characterized by repetitive episodes of cessation of breathing during sleep due to upper airway collapse. It causes sleep fragmentation, disabling daytime sleepiness, impaired cognitive function and poor quality of life. In addition, OSAS is associated with non-fatal and fatal cardiovascular consequences including sudden death, in addition to an increased risk of road traffic accidents. Continuous positive airway pressure (CPAP) is considered as the first-line treatment for OSA. Oral appliance has been shown to reduce the severity of sleep disordered breathing and leads to symptomatic improvement especially in mild to moderate OSA. The compliance with CPAP is low particularly in mild or moderate OSA patients and it is not a curative treatment of OSA. It has to be used in every night on a regular basis. Weight reduction has always been advocated in patients with OSA who are overweight and may lead to improvement in the severity of OSA. The existing studies about weight loss are limited by small sample size, short duration (<6 months), focus on very low calorie diet program or surgically induced weight loss program only. However, none of them have applied lifestyle modification program (LMP) which emphasizes on long term lifestyle and behavior change. Therefore, the investigators plan to conduct a randomized controlled trial among Chinese OSA patients by comparing the efficacy of LMP against usual clinical lifestyle advice alone on the improvement of OSA symptoms.
Obstructive sleep apnea syndrome (OSAS) and asthma are both common disorders in Hong Kong, with prevalence of at least 4% among the middle-aged male Hong Kong (HK) Chinese populations and 7.2% in young adults respectively. OSAS is characterized by repetitive episodes of upper airway obstruction, causing intermittent hypoxia, sleep fragmentation, disabling daytime sleepiness, impaired cognitive function and poor health status. Continuous positive airway pressure (CPAP) is the first line of therapy for sleep apnea. CPAP provides a pneumatic stent for the upper airway, eliminating the airway collapse during inspiration. Asthma is a chronic inflammatory disorder of airways, characterized by airway hyperresponsiveness that leads to recurrent episodes of wheezing, breathless, chest tightness, and coughing, particularly at night or in the early morning. Nocturnal asthma is not a different condition from asthma and is defined as a variable worsening of asthma at night, in which the mechanisms are not completely understood. The prevalence of OSAS in asthmatic patients has not yet been studied, but several studies have reported an increased prevalence of OSAS symptoms in asthmatic patients. OSAS and asthma share some common risk factors, which include obesity, gastroesophageal reflux and rhinitis. CPAP treatment has been shown in prospective clinical studies to have a positive impact on asthma outcome in patients with concomitant OSAS, for example, improvement of asthma related quality of life in subjects with stable mild-to-moderate asthma, but there was no change in the airway responsiveness or forced expiratory volume in one second. Although important, these studies included small numbers of participants used nonrandomized designs. This study is to assess the impact of CPAP treatment on asthma control among patients with nocturnal symptoms and moderate OSAS.
The purpose of this research study is to examine the effect of a couple-oriented education and support intervention on patient- and partner -reported outcomes (positive airway pressure (PAP) adherence) in patients newly diagnosed with obstructive sleep apnea (OSA).
