Filter by:The purpose of this study is to is to evaluate the efficacy and safety of retatrutide in participants with type 2 diabetes in participants who have obesity or overweight (J1I-MC-GZBK master protocol) including a subset of participants who have obstructive sleep apnea (OSA) (J1I-MC-GSA2). The study will last about 89 weeks and will include up to 24 visits.
The purpose of this study is to evaluate the efficacy and safety of retatrutide in participants who have obesity or overweight (J1I-MC-GZBJ master protocol) including subsets of participants who have knee osteoarthritis (OA) (J1I-MC-GOA1) or who have obstructive sleep apnea (OSA) (J1I-MC-GSA1). This study will last about 89 weeks and will include up to 24 visits.
In this study, the researchers are trying to learn more about the relationship between Polycystic Ovary Syndrome and Obstructive Sleep Apnea (OSA). Obstructive Sleep Apnea is a sleep-related breathing disorder that involves a decrease or complete stop in airflow. The purpose of this study is to find out why some people with obstructive sleep apnea have higher levels of insulin resistance, and the investigators will study the role of hypoxia (low levels of oxygen in the blood at night) in insulin resistance and see if insulin resistance improves during your treatment with CPAP.
The goal of this clinical trial is to assess the effect of CPAP withdrawal on vascular and autonomic function in patients with obstructive sleep apnea. The main question it aims to answer is: • Is the pulse wave amplitude index able to predict the impact of sleep apnea treatment withdrawal (continuous positive airway pressure, CPAP) on endothelial function and baroreflex sensitivity? Participants will stop using their CPAP for 2 weeks and the investigators will assess vascular and autonomic function before and after the withdrawal. Researchers will compare endothelial and autonomic function at baseline and after 2 weeks of withdrawal to see if there are differences. Moreover, they will assess the association between pulse wave amplitude drop profile and effect of CPAP withdrawal.
Uncontrolled hypertension is associated with an increased risk of heart disease, stroke, and mortality. Obstructive sleep apnea (OSA) is common in hypertension and treatment using continuous positive airway pressure (CPAP) has been shown to effectively lower blood pressure. Despite its clinical significance, OSA remains underdiagnosed in patients with hypertension, because the current standard of care to diagnose OSA is in-laboratory polysomnography, which is inconvenient and often inaccessible for high-risk populations. An alternative to in-laboratory polysomnography is home sleep apnea testing, which has been validated against in-laboratory polysomnography and may be more convenient, accessible, and potentially cost-effective. The objective of this study is to compare home sleep apnea testing to in-laboratory polysomnography in a randomized controlled trial. The investigators will assess whether the use of home sleep apnea testing, compared to use of in-laboratory polysomnography, leads to higher rates of OSA diagnosis and treatment using CPAP, a reduction in blood pressure, improved sleep-related outcomes, and greater patient satisfaction among patients with hypertension at 6 months. The investigators will also assess whether home testing is cost-effective.
Persistent daytime symptoms of sleepiness in individuals with obstructive sleep apnea (OSA) who are using Continuous Positive Airway Pressure (CPAP) are associated with adverse long term medical and functional outcomes. Supplementary exposure to bright light has beneficial effects on sleep quality and daytime vigilance in healthy individuals and it has been increasingly applied in a variety of sleep and neuropsychiatric conditions. This study will explore the role of Bright Light Therapy (BLT), a well-established non-pharmacological intervention for circadian disturbances, for the treatment of residual daytime symptoms of OSA which do not respond to CPAP. BLT will be delivered via therapy glasses in a cross-over design, where each participant will be exposed to active treatment and sham treatment (4 weeks in each arm) in a randomized order. The hypothesis is that participants will demonstrate improvements in the variables of interest during the four-week active treatment portion of the eight-week crossover study, compared to the four-week sham treatment portion.
The aim of this study is to assess the ocular parameters of drowsiness in patients with diagnosed Obstructive Sleep Apnea Syndrome through objective methods of ocular imaging and subjective evaluation methods (questionnaire)
The concept is a novel research idea that incorporates the potential impact of patient quality of life (QOL) on decision-making for treatment of mild obstructive sleep apnea (OSA). Our hypothesis is that in children with mild OSA there is significant conflict with parental decision-making; in the absence of significant sleep apnea, there is limited research regarding comparative efficacy of various treatment options. The impact of a QOL questionnaire can be a significant deciding factor and may help guide management decisions in such situations.
Obstructive Sleep Apnea is a common medical condition in children. Diagnosis is based on polysomnography . We conducted an open prospective non randomised clinical trial to assess the efficacy of a new medical device called SUNRISE.
To be able to diagnose obstructive sleep apnea syndrome (OSAS) in a patient, polysomnography (PSG) remains the gold standard. However, this is expensive, involves a considerable workload and is quite complex. Additionally, the wait time from when the patient was referred for PSG to when it is done can take up to 5-6 months. Simpler screening tools have therefore been developed, such as questionnaires. The questionnaires are subjective tools completed by the parents based on the observation of the child's sleep, behavioral problems, etc. These questionnaires have shown usefulness in sorting out patients to be referred to a sleep specialist, an Oto-Rhino-Laryngologist (ENT) or an orthodontist before performing a PSG in view of the difficulty of access to it. The Pediatric Sleep Questionnaire (PSQ) is a tool that was developed by Chervin and his colleagues to screen children with OSAS. This questionnaire is a reliable and scientifically validated tool. In addition, the PSQ is the most accurate questionnaire from a screening point of view. However, the American Academy of Pediatric Dentistry (AAPD) considers that the questionnaires, among others, the PSQ, are not sensitive enough to detect OSAS in a child. They offer an anamnesis as well as a clinical examination to be carried out in addition to the few questions taken from the PSQ that they consider useful for screening patients at risk. The investigators can therefore ask themselves the following question: "Is the PSQ sufficient on its own or do the investigators obtain better results when the investigators carry out a complete anamnesis as well as a clinical examination?
