Filter by:Chronic cough is an important clinical problem in primary care and sub-specialty practice. Besides the distress experienced by patients with chronic cough, significant healthcare resources are expended to understand the role of gastroesophageal reflux, asthma and post-nasal drip in understanding their contribution to cough. Obstructive sleep apnea (OSA) is common in patients with chronic cough. More importantly, treatment of OSA with continuous positive airway pressure (CPAP) has led to improvement in cough for chronic cough patients. Mechanisms by which OSA therapy with CPAP can improve cough includes beneficial effects on reflux and airway inflammation. The aim of this study is to definitively establish that CPAP therapy for treatment of OSA in chronic cough patients improves cough. While these patients with chronic cough are not routinely screened and treated for OSA, this study aims to evaluate these chronic cough patients with screening questionnaires for OSA and if necessary with polysomnography and randomize them to either CPAP or sham CPAP for 6 weeks.
Obstructive sleep apnea is a very frequent syndrome and Continuous Positive Airway Pressure (CPAP) is the gold standard treatment. Nevertheless, obtaining the sufficient compliance is complex. New communication technologies and the current health challenges, such as aging and high health care costs have encouraged the interest in new strategies. As showed recently, telemedicine is an alternative (Isetta, Thorax 2015) in patients that use internet and mobile technologies usually. However, there is a significant percentage of patients that does not use Internet and mobile technologies, only the 58% of patients over 65 years uses them (Dorsey, NEJM 2016). Although evidence regarding telemedicine is conflicting, it suggest that it's applicability depends in patient's characteristics and it is necessary to personalize it to make it safe and effective (Takahashi, Arch Intern Med 2012). That's why the investigators believe that the next step should be to choose those patient's that doesn't use Internet or mobile technologies and to verify the applicability of a telematic system that could facilitate the extra hospital management of this patient's. The aim of the study is to evaluate the telematic management of various outcomes that are emitted by CPAP machine, and by an app where the patient's will answer different questions regarding their treatment during the three months of study period.
Drug induced sleep endoscopy (DISE) is an increasingly performed procedure, offering dynamic upper airway evaluation during artificial sleep before surgical treatment for patients with obstructed sleep apnea (OSA). DISE is a safe procedure, easily practicable, valid and reliable. The investigators consider it a fundamental clinical procedure that is essential before choosing the surgical treatment. The investigator's results so far suggest that a multilevel collapse is significantly associated with higher apnea hypopnea index values. The investigators think that the weight did not play a significant role in RDI reduction. Results till now show that tailored surgery based on DISE may leverage sleep surgeries outcome significantly, presenting 70% success rate based on the investigator's experience The aim of this study is to evaluate surgery results in patients who underwent DISE prior to their surgery in comparison to their condition prior to the treatment.
Long follow up on patients with obstructive sleep apnea that undergo diagnosis and surgical treatment
The study objective is to satisfy the testing requirements for the Qualcomm Tricorder XPRIZE Competition. This requires an oversight model using the Vitaliti CVSM Wearable, Vitaliti Spirotoscope, and Vitaliti IVD Station to continuously monitor the patient's five core vital signs and to detect the health conditions required by the competition.
The investigators will compare the circulating fibrocyte proportion in asthmatic patients with obstructive sleep apnea (OSA) and not with OSA In addition, the investigators will compare the expression of epidermal growth factor receptor (EGFR), endothelin A receptor (ETAR) and connective tissue growth factor (CTGF) The association of those factors and annual decline of forced expiratory volume in 1 second (FEV1) will be performed
Positional therapy is considered as a kind of conservative treatment especially for patients with OSA which varies with body positions, and has been reported to be useful in selected cases especially those with positional OSA. Positional OSA is present when the overall apnea hyponea index (AHI) is > 5/hr with a supine AHI being more than 2 times of AHI in other positions, in a symptomatic patient. There will be 2 groups of patients in this study. Group 1 consists of patients with positional OSA who refuse CPAP or tolerate CPAP poorly. They will be provided with a vibration device as treatment, which will be worn on the neck during sleep. This device senses the position of the patient during sleep. It will vibrate when the patient lies supine until the patient turns laterally, thus prevents the patient to lie flat during sleep and reduce the severity of OSA. It will be switched on and off for a period of 15 days alternatively with sleep study performed at the end of each period respectively to determine its efficacy in the on and off mode. There will be a wash out period of 1 week in between the on and off period to remove any residual effect. Group 2 consists of patients with positional OSA who are using dental device but response or tolerated poorly. They will use the vibration device with dental device together as dual therapy, to assess the role of combination therapy. The device will be operated in on and off mode with sleep study being performed in a similar manner as in group 1. Informed consent will be signed. Each participant will have 2 sleep studies performed at home, which will be supported technically by technician visiting their home for hook up of necessary equipment.
The objective of the study is to compare the results of a follow-up and treatment coordinate and interactive program performed by the General Practitioners (GP) for Obstructive Sleep Apnea (OSA) patients treated with positive continuous pressure (CPAP) vs. usual control by sleep specialists from the sleep unit. METHODOLOGY: DESIGN: Randomized comparative study. It will include patients with diagnosis of severe OSA that should start treatment with CPAP. Participating center is Hospital Universitario Araba in Vitoria-Gasteiz (Spain). These patients will be randomized to two monitoring groups : 1 monitoring in the sleep unit; 2: monitoring in primary care consultations by the General Practitioners (GP), once the OSA diagnosis has been made and it was indicated the treatment with CPAP. Patients will be carried out in both groups the same follow-up visits in two study arms: basal, 1 month, 3 month and 6 months. PRIMARY OUTCOME: To compare the objective CPAP compliance treatment in the two study groups, so that use >= 4h/day is defined as good adherence to the treatment. SECONDARY OUTCOMES: 1)To evaluate the level of patient's satisfaction by visual-analogical scales and quality of life tests; 2) to establish the clinical improvement by somnolence and sleep scales; 3) To determine the numbers of CPAP complications, type, severity and duration; 4) To figure-out the level of take care of the CPAP machine, substitutions and complements, assistance and technical incidents; 5) Cost-effectiveness analysis.
The study aims to compare 2 different strategies used to setup non-invasive ventilation in patients with OCPD-OSA overlap.
The overall purpose of this study is to determine whether the oral medication dimethyl fumarate is an effective treatment for obstructive sleep apnea in patients who are unable, unwilling, or uneager to use positive airway pressure therapy.
