Filter by:The aim of this feasibility study is to compare different settings of a custom-made automated bed with respect to their ability to induce a change in the sleeping position of the user. In particular, it is of interest whether the bed mechanism is able to change the position of a user from supine to lateral position. At the same time, the investigators want to know whether the intervention provided by the bed results in an arousal in sleeping users. In addition, feasibility of detecting the position of the user using the un-obtrusive pressure sensors, which are integrated in the bed, will be assessed. Within the experiment, the investigators will identify participants that are sleeping mainly in supine position by doing an acti-watch based screening measurement in their home setting. Those participants who are sleeping in supine position for more than 12.5% of the home recording with the acti-watch will be invited to come to the lab for one night measurement. The experimenter will trigger interventions of the bed manually when the participant is lying in supine position. The investigators will evaluate the position change using infrared cameras and the built in sensors of the bed. Furthermore, a commercially available home-measurement device to record polysomnography will be used to evaluate whether the intervention caused arousals.
Obstructive sleep apnea (OSA) is a common chronic disease and associated with cardiovascular and neurocognitive sequelae. Overweight is a common, reversible risk factor of OSA, and the rapid rise in obesity worldwide may lead to increases in OSA and related adverse health outcomes. Weight-loss interventions, especially comprehensive lifestyle interventions, are associated with improvements in OSA severity, cardiometabolic comorbidities, and quality of life. However, the intensive nature of these programmes often pose a barrier to adherence. Furthermore, although there is strong evidence to support the value of mobile text messaging to promote physical activity and healthy eating in clinical and community settings, messaging has rarely been applied in interventions for overweight OSA subjects. The proposed study aims to examine the feasibility of a brief lifestyle modification programme that makes use of smartphone technology (WhatsApp or WeChat) to empower subjects to start doing simple and easy-to-do exercises that can be easily integrated into daily life for gradual lifestyle change.
In this study the investigators will evaluate chronotype, food intake pattern, and cardiovascular risk markers of elder individuals with OSA, in use of CPAP, when submitted to two weeks of CPAP withdrawal.
Sleep Apnea Syndrome (SAS) is a serious health issue that should be managed in order to limit its adverse health consequences. SAS is known to induce cardiovascular diseases, diabetes and depression. The prevalence of SAS is still growing with social and economic repercussion. Today, polysomnography (PSG) is the gold standard reference method for SAS diagnosis. However, it is a constraining and expensive technology. In order to improve patients' life quality, many new technologies have been developed for the SAS diagnosis. The aim of this study is to evaluate the Sunrise®, a new medical integrated solution for SAS diagnosis, in comparison with PSG. This solution consists in a chin sensor recording mandibular movements and measuring the respiratory event index (ERI) through an artificial intelligence algorithm analysis.
Prospective open-label, non-randomized, monocentric, cohort study, to assess the prevalence and severity of sleep apnea syndrome in patients treated for cancer of the upper aerodigestive tract. The patient follows a usual course of care including, at the end of the treatment of his cancer of the upper aerodigestive tract, screening for obstructive sleep apnea syndrome at 3 months and 6 months (Epworth score and ventilatory polygraphy)
The role of control of peri-pharyngeal muscle tone in the pathogenesis of obstructive sleep apnea (OSA) is obvious: pharyngeal obstruction occurs only during sleep; and pharyngeal collapse occurs in almost all healthy subjects during anesthesia. Better understanding of these control mechanisms may help identifying the central components of the pathogenesis of OSA.
The general objective is to evaluate the effect of continuous positive airway pressure (CPAP) treatment in patients with masked hypertension. The secondary objectives are: i) To evaluate the prevalence of different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) (dipper / non-dipper); ii) To assess in these patients the relationship between compliance with CPAP treatment and the response to nocturnal BP; iii) To identify variables of the ABPM, and biomarkers that are related to the unfavourable pattern of nocturnal BP response in these patients treated with CPAP; iv) To evaluate the change in the profile of biomarkers with the treatment. Methodology: Open, parallel, prospective, randomized and controlled study in which an ABPM will be performed in individuals with masked hypertension referred to the sleep unit and diagnosed of OSA (AHI≥ 30) without sleepiness (Epworth≤18). A total of 64 subjects with OSA and masked hypertension will be recruited. It will be collected blood for the determination of biomarkers. Subsequently, they will be randomized to receive treatment with CPAP (32) or conservative treatment (32). After 3 months of initiation, ABPM and biological determinations will be repeated.
The study is a thirty three week, prospective, open-label, randomized, parallel-group non-inferiority study. The study aims to investigate the Substantial Equivalence of a novel mandibular device called iSlpr™, produced by BioAnalytics, to a currently approved device, SomnoDent® Classic, in the treatment of mild to moderate Obstructive Sleep Apnoea (OSA) and snoring.
Apneic oxygenation is a process of delivering continuous oxygen during direct laryngoscopy. Nasal cannulas are used for the purpose of oxygenation; for delivering either low flow or high flow oxygen but haven't been tested in terms of a superior study design on improving patient outcomes. In this study the investigators propose to assess the effect of giving low flow oxygen with head side elevation versus high flow oxygen with head side elevation against the usual practice of care in which no oxygen is provided during direct laryngoscopy on participant's oxygenation level. This will be a three arm study instituting block randomization technique. There will be no blinding due to the nature of intervention. The primary outcomes are lowest non-invasive oxygen saturation measurement during direct laryngoscopy and two minutes after the placement of the tube and first pass success rate. The intervention is unique as the investigators have introduced head side elevation up to 30 degrees for improving glottis visualization and low or high flow oxygen delivery on grounds to improve oxygenation for patient safety undergoing endotracheal intubation. The technique if proved successful can be employed as a method of airway management in the emergency room. The results of the study will open new horizons for the development of guidelines to utilize it as a routine measure, during airway management in the emergency room.
The researchers in this study want to learn how drug BAY2586116 works in patients with obstructive sleep apnea (OSA). OSA is a sleep disorder marked by breathing pauses during sleep due to repetitive obstructions of the upper airway. BAY2586116 is a new drug under development for the treatment of OSA. It blocks protein channels expressed on the surface of the upper airways in small mechanoreceptors (a type of molecule that sense and pass stimulus outside a cell on to the inside of the cell through mechanical gate on the surface of the cell). Thus, the negative pressure reflex alerting the brain of inspiration is triggered more easily leading to a stronger activation of throat muscles. This prevents narrowing or collapse of the upper airways during sleep which is one of the pathological key factors in OSA. Researchers will study the effects of different routes of administration (drops into the nose, spray into the nose or throat or spray into the throat by endoscopy). Endoscopy allows the doctor to look at areas in the throat that cannot be seen with a mirror: a thin tube-like instrument is inserted through the nose to check and give the medication. Different doses of the test drug will be given. They also want to find out if participants experience any medical problems during the study. Patients participating in this study will undergo three study parts. After completing Part A and Part B, participants will be asked to join Part C. In Part A, participants will receive both the test drug and placebo (a placebo looks like the test drug but does not have any medicine in it); in Part B, participants will receive the test drug twice via different routes of administration (drops in nose and spray in nose or throat) and in Part C, the participants would receive the test drug once via spray in throat by endoscopy. The sleep of the participants will be monitored by medical equipment. Participants will be asked to visit the clinic 7 times in 14 weeks in total.
