Filter by:The purpose of this study is to evaluate the safety and tolerability of administering a single intravenous (IV) infusion dose of TAK-925 to adults with obstructive sleep apnea (OSA) who are experiencing excessive daytime sleepiness (EDS) despite adequate use of CPAP as the primary OSA therapy.
Assessment of the lung hyperinflation by bodypletysmography in patients with obstructive sleep apnoea treated with continuous positive airway pressure therapy.
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).
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.
This study evaluates epigenetics in morbid obese patients who are waiting for bariatric surgery. A home cardiopulmonary polygraphy is performed to evaluate for the presence of sleep-disordered breathing. The principal investigator make the decision of starting CPAP among patients with obstructive sleep apnea according to current clinical guidelines. One year follow up after bariatric surgery will be performed. A total of 5 visits will be scheduled: two of them before bariatric surgery and 3 after (3, 6 and 12 months). At every visit, all patients had: sleep questionaries, blood samples, EKG-Holter and spirometry are collected.
The aim of this study is to examine a new method of device configuration for the Inspire upper airway stimulator. First, the investigators will attempt to determine optimal configuration by quantifying changes in upper airway size with different implant configurations using awake nasal endoscopy. The configuration/voltage that results in the greatest increase in upper airway size and is tolerated by the patient will be selected. Participants will then undergo a sleep study so that increased airway size may be correlated with changes in sleep study parameters including AHI and oxygen desaturation index (ODI). Airway size and sleep study parameters using the standard device configuration (+-+)/voltage will be compared to airway size and sleep study parameters using the test, or "optimal," configuration/voltage to determine the usefulness of awake endoscopy in activation of the Inspire device.
The principal objective is to evaluate the effect of CPAP treatment on blood pressure (BP) in normotensive patients with nondipper circadian pattern with sleep apnea-hypopnea syndrome (SAHS). The secondary objectives are: i) To evaluate the prevalence of the different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) ii) To establish the relationship between CPAP compliance and BP response; iii) Identify which ABPM variables and biomarkers are related to BP response; iv) Evaluate changes in the biomarkers' profile after CPAP treatment. Methodology: Open-label, parallel, prospective, randomized and controlled trial including normotensive patients with nondipper circadian pattern diagnosed with severe SAHS without significant somnolence. 64 patients with nondipper circadian pattern will be included and will be randomized to receive CPAP (32) or conservative treatment (32). ABPM and blood sample collection will be performed at the beginning of the study and at 3 months.
