Filter by:The intended use of the Positive Airway Pressure (PAP) Problems Triaging Tool (TT) is to appropriately triage patients with a PAP-associated problem(s) to a specific intervention(s) based on patient responses. Thus, the proposed research will validate the tool, determine optimal scoring thresholds, and explore the utility of the tool as an indicator for intervention. Our central hypothesis is that the PAP Problems TT will identify treatment barriers that if unaddressed, are predictive of treatment non-adherence.
Sleep disordered breathing is associated with impaired glucose tolerance and incident diabetes. Nocturnal hypoxemia is a potential stimulus of glucose intolerance. It is especially severe and highly prevalent in high altitude residents. Intervening on nocturnal hypoxemia may therefore improve glucose control and decrease the public health burden in high altitude populations. The objective of this study is to examine the impact of hypoxemia on glucose homeostasis in high altitude residents. The investigators will address this objective by examining the effect of supplemental oxygen on glucose in a randomized cross-over study.
Serious mental illnesses (SMI) like schizophrenia and bipolar disorder are two of the most disabling and costly chronic illnesses worldwide. A high proportion of adults with schizophrenia and bipolar disorder have sleep disorders, like obstructive sleep apnea (OSA), but tend to be underdiagnosed and undertreated compared to the general population. This study aims to examine feasibility, acceptance, and impact of OSA treatment and how it affects cognitive function in people with SMI.
OSA is a chronic disease with high prevalence that parallels with increasing obesity. Self-management programmes are perceived to be cost-effective in long-term OSA patient care and can supplement regular medical treatments. The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group.
The purpose of the current study is to investigate whether alleviation of OSA by CPAP positively impacts glucose metabolism in non-diabetic patients.
Split-night prospective monocentric study to evaluate, in real conditions, the effectiveness of a disposable tracheal sound sensor.
The objectives of this study are: - To assess the effectiveness and cost-effectiveness of a vibrating positional device (NightBalance, Philips) in the treatment of positional obstructive sleep apnea compared to conventional CPAP treatment. - To investigate whether a positional device (NightBalance, Philips) avoids supine position after a period of use of the device without actively using the device for a subsequent period of time.
The role of obstructive sleep apnea (OSA) in contributing to hyperaldosteronism, which can lead to increased morbidity and mortality, is less well-established. The vitamin D levels and sympathetic activity of patients with obesity and OSA have not been explored in detail. In this cohort, the role of vitamin D and sympathetic activity, either individually or in combination, on augmenting the renin-angiotensin-aldosterone system (RAAS) causing more endothelial dysfunction remains elusive. We aim to evaluate renin angiotensin aldosterone system in OSA population; elucidate relationship between aldosterone and vitamin D levels in patients with OSA; and to determine association between aldosterone level and vitamin D deficiency with cardio-metabolic derangement in patients with OSA. This is a cross-sectional study involving 150 patients confirmed to have OSA. Participants who fulfil study criteria and consent to study will have blood withdrawn for aldosterone, renin, 25OHD levels with bone profile, and metabolic profile; undergo ultrasound flow mediated dilatation of brachial artery to assess endothelial function; ultrasound of hepatobiliary system to assess fatty liver; 24-hour Holter monitoring to assess sympathetic function; WHOQOLBREF to assess quality of life and Pittsburgh Sleep Quality Index to assess sleep quality.
Drug-induced sleep endoscopy (DISE) used as diagnostic tool but not yet as a therapeutic procedures to manage the upper airway of snorers and obstructive sleep apnea patients in conditions that mimic natural sleep, there are many aspects that need to be standardized in order to obtain reliable and reproducible information result in cryotherapy at sites of vibration as origin of snoring and site of collapse.
This is a digital health study in which participants are recruited to collect sleep and activity data from digital activity trackers. We are also collecting survey/questionnaire data on baseline health and sleep characteristics as well as bi-weekly assessments of sleep quality and mood. Overall, we aim to examine how sleep relates to physical and mental health in a large population of activity tracker users.
