Sleep apnoea (SA) is a common condition in adults and children that causes disturbed sleep and daytime symptoms. It is characterised by disrupted breathing with disturbed sleep patterns. In adults this can lead to dangerous daytime sleepiness affecting for example driving performance. In children it may lead to hyperactivity in the day and poor school performance. There are a number of techniques for diagnosing the disorder but they can affect the quality of sleep which sometimes makes them inaccurate. Most are unsuitable for small children who cannot understand the value of the tests and tend to remove the monitoring wires and devices in the night. This study aims to validate a new non contact device "Safescan", based on low power radar technology, which can be put under a bed and record breathing patterns with no measuring device in contact with the sleeper. In this initial study the device will be validated in adults, against the gold standard of polysomnography (PSG) in the sleep laboratory at Royal Papworth Hospital.
The primary objective of the PLUTO study is to evaluate the safety and tolerability of the ZENS transcutaneous nerve stimulator device in primary snorers and those with mild obstructive sleep apnea. The study will assess the impact of ZENS on snoring frequency, duration, and other relevant sleep parameters. The intended purpose of the investigational device is to deliver a transcutaneous electrical stimulation signal to the hypoglossal nerve in the "ON" phase in order to alter the apnea hypopnea index (AHI), as well as mean snoring burden (intensity, duration), and to deliver no signal in the "OFF" phase of the study as a means for comparison. Subjects utilizing the ZENS Device will experience a reduction in snoring during the "ON" versus "OFF" phase, as quantified by a reduction in the percentage of time per hour of snoring (≥40 dB) in the active ZENS Device ("ON" phase) versus the inactive ZENS Device ("OFF" phase).
Comparison of the prevalence of obstructive sleep apnea (OSA), measured by polysomnography in normal weight patients with central obesity by body mass index (BMI) and waist hip ratio (WHR), with normal weight patients without central obesity by BMI and WHR. Evaluation of arterial stiffness and vascular age in normal weight patients with central obesity and in normal weight patients without central obesity. Determination of the exercise response characteristics in OSA patients.
Sleep-related breathing disorders (SBAS) are one of the most common causes of non-restorative sleep. Sleep therapy options include positive pressure ventilation with continuous positive airway pressure (CPAP) masks, mandibular advancement of the mandible with mandibular advancement devices (MAD), back restraining, weight reduction, ear, nose and throat surgical procedures, bimaxillary or mandibular remodeling osteotomies, and neurostimulation procedures N. hypoglossal. In mild to moderate obstructive sleep apnea syndrome (OSAS), MAD, back suppression and weight reduction are potential treatment options. This study aims to identify possible side effects in the temporomandibular system that occur during nocturnal support of a mandibular arch over two years. Two different MADs are compared in terms of construction, height (bite elevation) and protrusion mechanics: the H-MAD with an hinge system according to Herbst and the SomnoDent Fusion ™ MAD (called F-MAD) with sliding side wings. In addition, it is to be evaluated whether hinge system according to Herbst as a protrusion-controlling element and the reduction of the splint body for a reduced bite elevation leads to a significant reduction of side effects compared to the F-MAD.
To study the effects of two combination therapies for patients with obstructive sleep apnea (OSA) who have been both intolerant to Positive Airway Pressure (PAP) therapy and sub-therapeutic to oral appliance therapy. Hypothesis 1. There is a difference between Continuous Positive Airway Pressure (CPAP) vs CPAP/Oral Appliance (OA) connect vs CPAP/OA disconnected in terms of: 1. Apnea Hypopnea Index (AHI) reduction 2. Amount of side effects 3. Amount of Leaks 4. Hours of use (compliance) 5. CPAP pressure 2. There is a difference between connected and disconnected for the following symptoms: 1. Epworth sleepiness Scale (ESS) 2. Functional Outcomes of Sleep Questionnaire (FOSQ) 3. Side effects Study Design - randomized prospective parallel
Sleep disorders are important health issues that can reduced ones quality of life by affecting their performance and productivity in a negative way. People who work in shifts or doing 24 hours call usually have irregular sleep patterns and often complaint of fatigue and daytime sleepiness. This will jeopardized our attention, concentration ability and memory which may lead to serious job accidents. This study is to screen for obstructive sleep apnea among doctors working in a tertiary hospital and to determine the predictors of OSAS and tiredness among doctors who frequently work night shifts or 24 hour call. What would this involve? Participant will be required fill up demographic data and answer the STOP-Bang and Epworth sleepiness scale questionnaires. After that participant will need to wear a wrist watch pulse oximeter just before going to sleep at night until the next morning (minimum of 6 hours of sleep required). The wrist watch will then be returned to researcher the following day for data analysis purpose. The benefits We hope to screen and identify those who are at risk of having obstructive sleep apnea and start early treatment among doctor who often have irregular sleep patterns and insufficient sleep due to the nature and timing of their work.
This investigation is designed to evaluate the comfort, ease of use and performance of a trial nasal mask for the treatment of Obstructive Sleep Apnea (OSA) in the home environment.
Background: Previous studies have reported that intermittent hypoxia in obstructive sleep apnea (OSA) is associated with tumor progression, metastasis and treatment outcomes. However, studies explaining the relationships between specific types of cancer and OSA are needed. In this study, it is aimed to show the effect of excessive daytime sleepiness as determined by Epworth sleepiness scale(ESS) and the effect of OSA risk determined by STOP BANG questionnaire on survival and treatment outcomes in lung cancer. Method: The patients who admit the palliative care outpatient clinic of our hospital with the diagnosis of lung cancer (stage 3 and stage 4 non-small cell lung cancer or limited / extensive stage small cell lung cancer) between July 2019-2020 will be assessed for excessive daytime sleepiness(EDS) and risk of obstructive sleep apnea (OSA) by Epworth sleepiness scale and the STOP-BANG questionnaire. The patients will be grouped according to the risk of OSA and EDS.Total / progression-free survival, treatment outcomes and side effects of the treatment will be evaluated comparatively.
This study aims to determine the overall accuracy, sensitivity, and specificity of the Belun Ring device in evaluating obstructive sleep apnea by comparing the device to the attended overnight in-lab polysomnography which is the gold standard for diagnosis of obstructive sleep apnea. Our hypothesis is that the Belun-Ring, a type 4 portable monitoring device, is overall sensitive and specific for evaluation of obstructive sleep apnea when compared to the attended overnight in-lab polysomnography.
