Active clinical trials for "Apnea"

To assess in moderate to severe Obstructive Sleep Apnea the effects of one year therapy with nighttime continuous positive airway pressure ventilation on the prevalence of metabolic syndrome and cardiovascular damage.

The purpose of the study is to determine the effect on mood and anxiety symptoms of adding CPAP to the psychiatric treatment of patients with TRD (treatment resistant depression) and associated OSA (obstructive sleep apnea).

A randomized single blind clinical trial, with a larger sample size than previous studies , to evaluate the effectiveness of injection snoreplasty in the treatment of patients with snoring and obstructive sleep apnea/hypopnea syndrome (OSAHS) compared to oropharyngeal exercises, a low cost therapeutic modality.

The purpose of this study is to examine the effect on blood pressure of 3 months of treatment with continuous positive airway pressure (CPAP) in patients with obstructive sleep apnea (OSA). Hypothesis: Central 24-h blood pressure (BP) monitoring hedges day fluctuations in blood pressure more accurately than peripheral 24-h BP monitoring, because the measurement is painless and does not interfere with the patient / subject's activities during the daytime or nighttime sleep. Blood pressure is elevated in patients with OSA and falls during treatment with CPAP. 3. The renal treatment of salt and water is abnormal in OSA, improved during treatment with CPAP. 4. Quality of life improves during treatment with CPAP

Obstructive Sleep Apnea (OSA) is a common clinical problem with a reported prevalence of 2% to 4% in the general population. The incidence was double on patients who had a diagnosis of OSA going for orthopedics surgery. Little literature composed mostly of case reports or small retrospective case-control studies exist examining the use of intrathecal opioids on outcomes in OSA patients is inconclusive. The primary objective of this study is to compare the post operative respiratory effect after single dose intrathecal morphine and intrathecal fentanyl on orthopedics patients who suspected or undiagnosed obstructive sleep apnea. Hypotheses Undiagnosed OSA patients who received intrathecal morphine are more likely to have respiratory events post-operatively.

Patients with Congestive Heart Failure (CHF) on non-Intensive Care Unit medical services and/or visiting our outpatient Congestive Heart Failure Clinic will be screened using the STOP-BANG Scoring Model. (STOP-BANG stands for Snoring, Tiredness, Observed Apnea, Blood Pressure, Body Mass Index, Age, Neck Circumference, Gender.) Patients with high risk of Obstructive Sleep Apnea (OSA) will be referred for evaluation and treatment of Sleep Apnea. They will be followed to determine if treatment of Sleep Apnea improves their quality of life and decreases their utilization of the Hospital and Emergency Department (ED).

Many researches have shown that patients with Obstructive Sleep Apnea (OSA) and often also the family members have a decreased quality of life, problems related to the sexual sphere, depressive disorders and anxiety problems. To date still remains controversial the relationship between OSA and quality of life, also the link between sleep apnea syndrome and depression is unclear. In adult patients with OSA the treatment of choice is the application of a continuous positive airway pressure (CPAP: Continuous Positive Airway Pressure) at the opening of the airways. With the CPAP treatment the sleep normalizes and daytime sleepiness fades or disappears. Many studies have shown that this treatment determines improvement of the medical and psychological status. However, the rate of non-adherence to treatment reported in the literature is about 46-83%, considering as adherence the use of CPAP for at least 4 hours per night. A recent study has shown that CPAP used as a single treatment in patients with OSA and depression, has reduced the depressive symptoms but in a significant percentage of patients (42%), the depressive symptoms remained unchanged or worsened. At the present time have not been published, to our knowledge, studies concerning the effectiveness of the combined treatment of CPAP and psychological support on the mood and on the quality of life OSA patients. Therefore the aim of this study is to evaluate the effects of the combined treatment with CPAP and psychological intervention with cognitive behavioural therapy on the mood and on the quality of life of OSA patients.

To investigate the accuracy of neck ultrasound in identifying and discriminating the severity of obstructive sleep apnea (OSA). Primary objective: To test the hypothesis that ultrasound can be used as a reliable tool for identifying the anatomic characteristics and dynamic changes of pharyngeal airspace in patients with OSA. Secondary objective: Investigate if ultrasound can be used to discriminate OSA severity. The investigators will compare these results to the results from polysomnography study.

This study intends to determine whether continuous positive airway pressure (CPAP) can reduce arterial stiffness (measured by pulse wave velocity) in nonsleepy as well as in sleepy patients with obstructive sleep apnea .

Targeted population: Sleep apnea patients at low cardiovascular risk newly treated by CPAP Hypothesis: Six months CPAP compliance might be greater in the telemonitoring arm compared to usual CPAP care. Main goal: To compare 6-months CPAP compliance when Sleep Apnea patients at low cardiovascular risk are randomly allocated to usual CPAP care or a multidisciplinary and coordinated follow-up based on a telemonitoring web platform.
