Filter by:Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. However, this device is not effective or tolerated in all individuals. The goal of this study is to examine whether a medication called acetazolamide can improve SDB, as an alternative to CPAP treatment. The investigators will measure the improvement in SDB, as well as any change in symptoms, during a 1 week treatment with acetazolamide compared with 1 week of placebo (sugar pill). This study will help to provide data for longer term studies of treatment for SDB in patients who use opioids.
The ExVent is an optional accessory to the O2Vent Optima MAD and provides oral Expiratory Positive Airway Pressure (EPAP). Oral EPAP with the ExVent is designed to provide upper airway support via similar mechanisms of action of nasal EPAP devices in commercial distribution, e.g., passive dilatation of the airway, which reduces flow limitation. Nasal EPAP devices are in commercial distribution as stand-alone therapies for the treatment of OSA. The oral EPAP provided by the ExVent accessory is designed to augment the OSA therapy provided by the O2Vent Optima.
This is a prospective longitudinal cohort study whereby pregnant individuals are asked to complete an 8-day testing protocol to measure their sleep and cardiovascular health at two timepoints during pregnancy.
Children with medical complexity (CMC) often have trouble breathing at night and need to use a breathing machine. This breathing machine is called noninvasive positive pressure ventilation (NiPPV). The use of NiPPV has been shown to improve quality of life and survival in children. Before it is used, NiPPV must first be tested to see what the correct 'machine settings' are for each child. This is usually done in the sleep laboratory at the hospital during a one-night stay. However, sleep studies in the hospital are disruptive and hard for CMC and their families because of the new environment and limited access to the equipment, supplies, comfort items and the routine their child has at home. Patients and families would prefer to start NiPPV at home but there needs to be more research on this to make sure it is possible and safe. This study will evaluate a new model of care to start NiPPV in the home. CMC aged 5-17 years old and starting NiPPV will be assigned at random, like a coin toss, to start NiPPV in the home or to start NiPPV in the sleep laboratory. The investigators will assess the feasibility and safety of the two ways to start NiPPV. This study will be the first step towards developing a study to evaluate if home NiPPV starts are effective. Starting NiPPV at home has the potential to improve the use of NiPPV (ie early adherence predicts long-term use) resulting in both medical benefits as well as improved quality of life for CMC and their families.
The clinical hypothesis of this study is that a currently marketed mouthguard may also be able to reduce the symptoms of sleep-disordered breathing in children.
Background: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) is the most common periodic fever syndrome of childhood. Symptoms can include swelling of the glands in the throat, mouth ulcers, and tonsillitis. Removal of the tonsils can stop the periodic flareups. But researchers do not know how PFAPA develops. In this natural history study, researchers will collect specimens and data from people with PFAPA to see what they might have in common. Objective: To collect blood and other specimens from people with PFAPA to learn more about the illness. Eligibility: People aged 1 month or older with symptoms of PFAPA or another tonsil disorder. Design: Participants will be screened. Their medical records will be reviewed. Researchers will ask about a family history of PFAPA. The following specimens may be collected: Blood. Blood will be drawn either from a needle inserted into a vein or from a prick in the finger or heel. Mucus and cells. A stick with soft padding on the tip may be rubbed inside the nostrils or mouth. Stool. Saliva. Tissue samples may be taken if participants are having surgery to remove the tonsils or adenoids. Participants having surgery may also have a nasopharyngeal wash; salt water will be squirted into the back of the throat and then sucked back out with a syringe. Most participants will provide specimens only once. They can do this in person at the clinic; they can also have their local health providers send specimens to the researchers. Some participants may have optional follow-up visits over 10 years.
There is an increased risk for sleep disordered breathing (SDB), sleep-related hypoventilation and irregular breathing in individuals on chronic prescription opioid medications. Almost 30% of a veteran sleep clinic population had opioid-associated central sleep apnea (CSA). The proposal aims to identity whether oxygen and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in chronic opioid use via different mechanisms. We will study additional clinical parameters like quality of life, sleep and pain in patients with and without opioid use. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea with opioid use. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea.
The goal of this treatment study is to determine if doing lateral pharyngoplasty with tonsillectomy is better for children than doing tonsillectomy alone. The main questions it aims to answer are: - Do children experience less pain after surgery when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? - Do children eat/drink better when lateral pharyngoplasty is performed with tonsillectomy compared to tonsillectomy alone? - Is there a lower risk of bleeding after tonsillectomy when lateral pharyngoplasty is performed? Researchers will compare children undergoing tonsillectomy and lateral pharyngoplasty with children undergoing tonsillectomy alone to see if the participants experience less pain, better oral intake, and less bleeding complications after surgery. Parents of participants will be asked to record pain scores and pain medications given, approximate amounts of daily oral intake, and any complications after surgery.
Obstructive sleep apnea (OSA) is prevalent in patients with stroke and has a negative effect on outcomes by predisposing them to recurrent stroke, increasing mortality, and so forth. Therefore, it is extremely important to identify OSA in patients with stroke. Wearable devices can greatly reduce the manpower and material requirements of traditional laboratory-based polysomnography (PSG). With Photoplethysmography (PPG) technology and neural network algorithms, the Belun ring and the sleeping platform not only can detect blood oxygen, and heart rate but also can identify sleep stage and estimate the severity of sleep apnea. In this study, inpatients with acute ischemic stroke in the hospital will proceed with three nights test for recording the parameters of the autonomic nervous system in the acute phase, evaluate whether sleep apnea and the feasibility of the Belun sleep platform. It is important that early recognition of OSA and prompt treatment, which can potentially improve OSA-associated adverse outcomes, as well as understanding the degree of autonomic nervous function impairment for patients with acute ischemic stroke. After smoothing this process, it can help clinicians more accurately comprehend the condition, timing of admission, and discharge.
SLeeP AID4 is a single-group, single-arm, Canada-wide, non-randomised, unblinded, in-home, observational study to prospectively collect and build a data set of natural sleep behaviour and physiology in maternal-fetal dyads (and bed partners, if applicable) in the third trimester of pregnancy in the home setting and subsequently investigate the feasibility of using computer vision technology (CVT) to monitor sleep during and across the third trimester of pregnancy in the home setting for research purposes by eliciting participants' attitudes toward CVT and training, validating, and testing a CVT model to accurately, unobtrusively, non-invasively, and objectively detect and quantify various sleep behaviours, disturbances, and disorders.
