Active clinical trials for "Apnea"

This study evaluates the utility and reliability of Somnocheck micro Weinmann for obstructive sleep apnea syndrome (OSAS) screening in patients affected by resistant systemic arterial hypertension. Results are compared with a modified portable sleep apnea testing (type III portable monitoring: Somnocheck 2 Weinmann).

This is an observational study involving chart review of patients seen in the bariatric clinic since 2012 at The Ohio State University (OSU). Obese patients will be divided into two groups according to their metabolic profile (healthy vs unhealthy). The assignment to each group will be determined by the presence of diagnosis of hypertension, diabetes mellitus and/or dyslipidemia. The presence of at least 2 diagnoses will be defined as metabolically unhealthy. Then, each group will be divided based on the presence of Obstructive Sleep Apnea diagnosis. All data will be collected through a review of the patient's electronic medical record from the bariatric clinic database (the investigators will collect variables as age, gender, race, BMI, smoking status, the presence of diagnosis as Obstructive sleep apnea, hypertension, diabetes, hyperlipidemia). The investigators will analyze that data and establish if there is any correlation between sleep apnea and the subjects' metabolic profile.

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.

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 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.

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.

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.

Obstructive sleep apnea (OSA) is a clinical condition characterized by the repetitive obstruction of the upper airway during sleep, resulting in nocturnal hypoxaemia and fragmented sleep. Fragmented sleep leads to daytime sleepiness that causes alterations in reaction times and reflexes . Postural stability is an important function of the human body. It is shown that the sleep deprivation disturbs daytime postural stability and balance. Aim of this study is to examine the influence of OSA severity and daytime sleepiness on postural stability, balance and fall risk.

Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults that has been strongly associated with various forms of cardiovascular disease. Compared to the general population, OSA occurs more often in patients with acute coronary syndrome (ACS). Although percutaneous coronary intervention (PCI) is nowadays part of standard therapy and optimal medical therapy has been used to manage traditional risk factors, the long-term cardiovascular outcomes after index ACS remain suboptimal. Some preliminary data suggest OSA is associated with higher risk of subsequent cardiovascular events in ACS patients. However, the study population was heterogeneous and these studies were not done in the context of new-generation drug-eluting stents and intensive antiplatelet therapy, thus precluding definite conclusions. Furthermore, a cardioprotective role of OSA in the context of acute myocardial infarction (AMI), via ischemic preconditioning, has also been postulated. Due to the inconsistent evidence, the investigators performed a large-scale, prospective cohort study to delineate the whole picture of the association of OSA with short- and long-term outcomes of patients with ACS. Whether treatment of OSA (eg. continuous positive airway pressure (CPAP)) would prevent these events will also be evaluated. Moreover, the investigators will assess the potential mechanisms of OSA-induced atherosclerosis and myocardial injury in ACS patients.
