Filter by:This clinical trial will compare home sleep apnea testing with the gold standard in-lab polysomnography in terms of 1) accuracy, 2) therapeutic decision-making, and 3) parent/child acceptability in children referred for evaluation of obstructive sleep apnea.
Obstructive sleep apnoea is a highly burdensome condition that not only impairs function but also confers a risk of cardiovascular disease. This is particularly evident among those who are poorly compliant with continuous positive airway pressure ventilation therapy. In the management of a chronic and frequent pathology such as OSA, it is necessary to have personalized programs that implement new technology-based tools to improve the comprehensive management of the patient in order to reduce the morbidity associated with this disease.
The purpose of this study is to test a pediatric narcolepsy patient reported outcomes tool to assess pediatric narcolepsy symptoms and their effect on daily functioning and quality of life. The goal is to develop a clinical survey that can improve the care of pediatric narcolepsy.
This research study is being done to determine whether the repetition and resistance from the daily use of the myofunctional therapy (MT) nozzle will improve obstructive sleep apnea and primary snoring.
Moderate to severe obstructive sleep apnea syndrome (OSAS) (HAI hypopnea apnea index ≥ 15) is a common pathology, which affects 6 to 17% of the general population. The Alaska study, which involved 480,000 apneic patients newly fitted with CPAP, showed that 76.9% of patients were still under treatment for one year, 62.9% after two years, and 52.3% after three years. All patients who recently diagnosed with OSAS in the Sleep Disorder Unit (unity de Pathologies du Sommeil et de la Vigilance, CHU d'AMIENS-PICARDIE, FRANCE) and who are requiring CPAP will be included. On the day of their hospitalization for the implementation of the CPAP therapy, patients will answer validated questionnaires to assess their level of motivation and adherence to the initiation of treatment but also to assess their knowledge and understanding of the disease and its treatment. These questionnaires will be repeated at the four-month and one-year follow-up consultations (+/- 21 days). The aim of the study is to identify the prognostic factors of adherence to CPAP, leading to a better understanding and management of patients with sleep apnea syndrome.
Obstructive sleep apnea (OSA) is highly prevalent in children and is often caused by overgrowth of the child's adenoids and/or tonsils. Consequently, adenotonsillectomy (removal of the tonsils and adenoids) is the most common treatment of OSA in children, although just the tonsils or adenoids may be removed depending on the case. As well, OSA in children is often associated with cognitive dysfunction and mood issues, suggesting brain changes due to the condition. However, the link between brain changes, cognitive and moods issues, and OSA in children has not been thoroughly explored. Therefore, this study aims to examine brain changes, cognition and mood in pediatric OSA subjects compared to controls as well as before and after removal of the adenoids and/or tonsils. This study hopes to enroll 70 subjects, ages 7-12 years, 35 healthy controls and 35 subjects diagnosed with OSA and scheduled for an adenoidectomy and/or tonsillectomy. Control subjects will schedule one visit to UCLA and OSA subjects will schedule two. Upon the first visit, all subjects will undergo cognitive, mood and sleep questionnaires and MRI scanning. That will be the duration of the controls' participation in the study; however, OSA subjects will return 6 months later (after their adenoidectomy and/ or tonsillectomy) to repeat the same procedures. Sleep quality, mood, cognition and brain images will be compared between OSA and controls and between OSA subjects before surgery and after surgery.
Hypothesis: Patients with obstructive sleep apnea syndrome (OSAS) have cochlear receptor cells damage because of prolonged, recurrent hypoxia. The use of devices operating under the continous positive airway pressure (CPAP) leads to the recovery of cochlear receptor cells. Aims: 1. To determinate whether there is cochlear receptor cells damage in OSAS patients depending on the degree of the disease 2. Investigate whether the use of ventilation devices with continuous positive pressure and constant oxygen pressure in the airways can lead to the recovery of the cochlear receptor cells Participants and Methods: The investigation work will be designed as original scientific research- prospective cohort study at Department od Otorhinolaryngology and Head and Neck Surgery, University Hospital Center Osijek. The participants will be divided in two groups: target group with obstructive sleep apnea (n45) and control group with healthy individuals (n32). Research plan: All participating in this study will complete the following questionnaires: STOP- BANG and Epworth drowsiness scale. Subjects of the target group with moderate or severe obstructive sleep apnea will be referred to an otorhinolaryngologist audiologist for complete examination and processing after examination by a neurologist. These participants will be examined by an audiologist after 6-8 months of continuous and adequate use of the CPAP device for reevaluation. Participants of a control group will be patients examined or treated in Department of Otorhinolaryngology and Head and Neck surgery for other diseases in whom specific questionnaires excluded the existence of obstructive sleep apnea. Audiological diagnostics will be performed on all patients on the same devices of the Department of Audiology and Phoniatrics . Expected scientific contribution: To prove the existence of receptor hearing impairment in the patients with obstructive sleep apnea; and then to prove that the use of a of continuous positive airway pressure with constant oxygen pressure in patients with OSAS using CPAP devices leads to the recovery of the cochlear receptor cells whose damage occurred as a result prolonged recurrent hypoxia. In addition, to determine the importance of a broader diagnostic processing of patients with obstructive sleep apnea.
This study will evaluate the effect of CPAP therapy on esophageal pH and lung inflammation in patients with idiopathic pulmonary fibrosis (IPF) and sleep apnea.
Obstructive sleep apnea (OSA) and non-alcoholic fatty liver disease (NAFLD) are both common diseases related to metabolic diseases with potential cardiovascular consequences and liver complications respectively. Though studies show OSA may take part in the progression of hepatic steatosis, the independent contribution of OSA on liver fat accumulation is unknown. It is hypothesized that nocturnal intermittent hypoxia from OSA is the main driver of NAFLD in non-obese OSA patients. This study is to assess the effect of OSA on NAFLD in non-obese patients.
Obstructive sleep apnea (OSA) is a disorder where a person has recurrent choking episodes during sleep. Surgery can treat OSA and drug induced sleep endoscopy (DISE) is a procedure that surgeons use to evaluate the throat while a person is sedated, mimicking sleep, to help determine if surgery might be effective. Lung volume can influence OSA severity but the relationship between lung function and throat collapse seen on DISE has not been well studied. This study aims to see if lung volume influences what is happening in the throat during DISE. Participants will be recruited from the sleep surgery clinic where they are being evaluated for surgery to treat their OSA. Participants will have a DISE that is performed as part of their routine surgical workup for treatment of OSA. Additionally, during the DISE, they will participate in one of two study groups. One group will have a negative pressure "turtle shell" ventilator placed over the participants chest during DISE to manipulate lung volumes to see if it can improve throat collapse. A second group will have electrodes placed over the neck to stimulate the phrenic nerve to contract the diaphragm to improve lung volumes to see if it can improve throat collapse. Both groups will also have a lung function test performed.The findings of this study will be important in improving pre-surgical evaluation of patients to better predict if surgery can help as well as potentially develop new surgical therapies for the treatment of OSA.
