Active clinical trials for "Sleep Apnea, Obstructive"

Quantitative Genioglossal muscle strength in Obstructive Sleep Apnea (OSAS) defined in the clinical spectrum of subjects with Snoring Disturbance, Oral Appliance Therapy Responsive, and CPAP Responsive

Continuous positive airway pressure (CPAP) is the first choice of treatment for moderate to severe obstructive sleep apnea syndrome (OSAS). Although adherence is critical for achieving a good treatment effect, and early intervention if treatment problems emerge is important for achieving good adherence, information on patient compliance is usually based on assessment of the first few weeks of treatment. Telemedicine technology allows for monitoring of CPAP pressure, air leaks, apnea-hypopnea index (AHI) and compliance on a daily basis and could therefore be an option allowing for adequate support and quick response if a patient has problems with the treatment. In addition, improving early experiences of CPAP, identifying patients in need of more intensive support could potentially improve adherence but also reduced cost of care, and increased patient satisfaction. The proposed study will recruit 200 OSAS patients starting CPAP treatment; 100 patients randomized to afterwards receiving telemonitoring in combination with telephone calls, and 100 patients randomized to receiving usual office visits. All patients will in addition answer questionnaires on sleep and health, quality of life, and patient satisfaction after the first CPAP information visit and then again after 6 months of treatment. At time of follow-up all patients will also answer questionnaires on side effects of CPAP. Health economic variables will also be measured throughout the testing period. The study will provide valuable information regarding benefits of telemonitoring in clinical work with CPAP therapy. Implementation of telemedicine-based monitoring of CPAP therapy may be an important part of increasing adherence among patients but also in the development of a more cost-effective care as it can provide clinics with increased treatment capacity and follow-up of both new and established patients. It would further improve the care for these patients who often have a lifelong treatment, which aims to reduce the risk of developing cardiovascular disease or premature death.

This study evaluates the use of the STOPBANG questionnaire to predict whether a pregnant woman with class III obesity has obstructive sleep apnoea. All participants will have a STOPBANG score and modified STOPBANG score (substituting Epworth score > 10 with the tired item) calculated and then be tested with overnight pulse oximetry to see if they meet ODI criteria for obstructive sleep apnoea.

Incidence of difficult laryngoscopy and difficult intubation are higher among patients with obstructive sleep apnoea (OSA). Precision in making the diagnosis and predicting difficult laryngoscopy preoperatively may help to reduce anesthetic complications. This study was designed to evaluate the diagnostic performance of combined and non-combined radiological parameter (mandibulohyoid distance) and STOP-BANG questionnaire as screening tool. . Methodology: Forty-one subjects who were at risk of OSA, undergoing general anaesthesia will be included using STOP-BANG questionnaire. Mandibulohyoid distance and other radiological parameters will be measured from lateral cephalometry. Evaluation for difficult laryngoscopy will be carried out during anaesthesia.

The prevalence of sleep-disordered breathing in Republic of Korea is 27% and 16% in men and women aged 40-69 years. Up to 93% of women and 82% of men with obstructive sleep apnea (OSA) remain undiagnosed. Polysomnography, the gold standard, is time consuming and costly. Patients with undiagnosed OSA may experience obstructive episodes during procedures with conscious sedation. STOP-Bang questionnaire is the validated questionnaire to screen patients for undiagnosed OSA in the preoperative setting. It has high sensitivity (92.9%) for predicting patients with moderate to severe OSA. Previous studies reported that STOP-Bang questionnaire predicted cardiopulmonary events during advanced endoscopic procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound. However, there have been no studies regarding the risk for sedation-related cardiopulmonary events in patients with undiagnosed OSA undergoing bronchoscopy. Thus, we aimed to evaluate the prevalence of high-risk patients for OSA by a screening questionnaire, and to determine whether the questionnaire could predict patients who are at risk for cardiopulmonary events during bronchoscopy with conscious sedation.

Diabetic retinopathy (DR) is the most common visual complication of diabetes. Risk factors for developing DR are diabetes duration, glycemic control, and hypertension . The prevalence ranges from 17 to 61% according to the diabetes duration . Obstructive sleep apnea syndrome (OSAS) is very frequent in Type 2 Diabetes population, reaching a prevalence of 23-48% . Few is known about the exact role of OSAS in the development of DR. A recent study has shown that OSAS is an independent predictor for the progression to pre-/proliferative DR. The purpose of the present study is to assess if the presence of OSA in diabetic patients is a predictive factor for DR occurrence.

This observational study in a real-world community was designed to perform epidemiological investigation and assess effect of CPAP intervention of obstructive sleep apnea.

Higher risk of cardiac and respiratory post-operative events is observed in patients with unrecognised Obstructive Sleep Apnea (OSA). The efficiency of a simple method of OSA screening by analysing ventilation with measurement of nose pressure and nocturnal hypoxemia (oxygen desaturation index) will be assessed. These sleep respiratory analyses will be compared with the research of arrhythmia, in order to show if they are linked to the hypoxemia events. Aggravation of nocturnal respiratory disorder and higher incidence of cardiac and respiratory postoperative complications will be assessed in OSA patients.

This multicenter prospective trial will evaluate the association between obstructive sleep apnea (OSA) and blood biomarkers in a representative population of consecutively enrolled symptomatic patients with a clinical suspicion of OSA.

Sleep apnea involves significant increases in disease and death, but its consequences in people over 65 years of age are incompletely recognized. Intraoral mandibular advancement appliances reduce the number of apneas and hypopneas. The investigators hypothesized that oral appliances provided to the elderly may prevent hypertension and other consequences of sleep apnea in large populations, at a favorable cost/benefit relationship for the public health system.
