Obstructive sleep apnea is a chronic condition that has serious health consequences including increased risk of hypertension, type-2 diabetes, heart disease, stroke and reduced life expectancy. This study proposes to use behavioral reinforcement and support to increase adherence to oral appliance therapy for obstructive sleep apnea. The control group in the study will receive routine care. In addition, their oral appliance wear time will be monitored using a sensor built into the appliance. Routine care includes an initial 1-hr consult, then delivery of the oral appliance (with sensor) and follow-up appointments at 1 week, 1 month, 3 months, 6 months, and 1 year. The second, experimental group will receive adherence promotion techniques in addition to routine care. These adherence promotion techniques can be categorized into 6 methods. 1- spouse/partner included in a patient counseling session. 2- Educational brochure delivery at follow up appointments. 3- Electronic reminder/communication system established by patient and provider. 4-Follow up communication between primary care physician and orthodontist. 5-Celebratory certificate for good adherence with the oral appliance evaluated at 3 month, and 6 month visits. 6-Gift card delivery, $25, when patient schedules a follow up with sleep physician. Patients will be followed for within the research protocol for 6 months. There are no additional risks involved with the research and the anticipated benefit is to develop methods to increase adherence to treatment for obstructive sleep apnea. This will benefit many patients with obstructive sleep apnea who use oral appliances to control the condition.
Simultaneous operations on the thyroid gland and hyoid suspension in patients with combined thyroid pathology and moderate to severe OSA.
Millimeter wave radar will be used to conduct non-contact monitoring continuously for patients' vital signs (eg. respiratory rate, heart rate, and chest/abdominal movement). The monitoring information will be transmitted to the central system through network and displayed in real time. Comparison with polysomnography will be done to examine the consistency between the two devices in diagnosing sleep breathing disorders. The predictive model of acute exacerbations of COPD will be established with the baseline indicators considered.
The purpose of this study is to evaluate the safety profile of the novel oral appliance (OA )device and to assess patient comfort of the novel OA device.
The ROCK (Rho-associated coiled-coil containing kinases) play a critical role in the pathogenesis of cardiovascular diseases and left ventricle hypertrophy (LVH). ROCK activity can be used as a clinical biomarker for the diagnosis and monitoring of cardiovascular disorders. Obstructive sleep apnea (OSA) increase cardiovascular disease and LVH. Continuous positive airway pressure (CPAP) is the standard therapy for OSA. This study investigate the effect of CPAP on ROCK activity and left ventricle mass.
Sleep apnea is a common under-diagnosed medical disorder, and moderate to severe disease is found in approximately 9% of men and 4% of women. The disease is characterized by repetitive collapse of the airway during sleep, causing sleep disruption, episodic low oxygen levels, and daytime sleepiness. Also, patients with sleep apnea are at high risk of developing cardiovascular disease (including strokes and heart attacks). Partly, this is because the episodic low oxygen levels followed by higher oxygen levels due to sleep apnea results in the generation of reactive oxygen species (unstable and potentially toxic substances caused by interactions with oxygen) and a state of "oxidative stress." Oxidative stress is an important contributing factor to heart disease. We are interested in determining whether treatment with antioxidants, which are substances that help reduce oxidative stress, helps cardiovascular health in patients with sleep apnea. Specifically, we want to determine whether treatment improves blood vessel function (an early sign of heart disease), and blood/urine markers of cardiac risk (i.e., inflammation and oxidative stress). Eighty adult patients with moderate to severe sleep apnea will be asked to participate. They will have their blood vessel function measured with a non-invasive finger probe, and blood/urine will be collected to measure the cardiac risk markers. Patients will then be 'randomized' to one of two groups: 50% chance that the patient will be asked to take an antioxidant, and a 50% chance that they will be asked to take a placebo tablet (though he/she will not know which one they are taking). After 8 weeks, blood vessel function and markers will be remeasured to determine if antioxidants help patients with sleep apnea.
This is a prospective interventional study to better understand i) the prevalence of Obstructive Sleep Apnea (OSA) in Heart Failure with preserved Ejection Fraction (HFpEF), ii) its hemodynamic correlates, and iii) the impact of intervention with Continuous Positive Airway Pressure (CPAP) on quality of life.
The purpose of study JZP110-401 is to evaluate solriamfetol pharmacokinetics (PK) in the breast milk and plasma of healthy postpartum women following the administration of the drug. The study also aims to estimate the potential daily solriamfetol dose received by the infant from the breast milk of the nursing mother. The safety and tolerability of single oral doses of solriamfetol will also be assessed.
Polysomnography (PSG) has some disadvantages, such as time-consuming, effort-consuming, long appointment time and high cost. During PSG examination, multiple sensors need to be placed in the patient's head, face, neck, chest and limbs, and sensors are needed to monitor data throughout the night. It is difficult for young children to cooperate, and it is easy to fail due to inaccurate sensor signal acquisition. PSG examination may miss diagnosis or underestimate the disease due to the first night effect. Based on the above reasons, the application of PSG in clinic, especially in pediatric patients is limited. The reflective optical path detection can be used to measure the peripheral blood oxygen saturation in the flat part of human skin. The investigators intend to use a reflectance pulse oximeterto evaluate its reliability and validity in the diagnosis of OSA in children at the same time as PSG.
