Filter by:Obstructive sleep apnea (OSA) has been associated with cardiac repolarization abnormalities and implicated in sudden cardiac death. A biologically plausible mechanism by which OSA exerts this lethality is by QT interval prolongation, a known marker of ventricular tachyarrhythmias (VTA) leading to cardiac death. Congenital long QT syndrome (LQTS) is a familial arrhythmogenic disorder characterized by prolonged QT interval on the electrocardiogram and increased propensity for VTA. Preliminary data identify an association of the extent of severity of OSA and progressive prolongation of the corrected QT interval in LQTS.
Obstructive Sleep Apnea (OSA) is a common disorder with serious consequences that remains underrecognized, with >80% of OSA patients undiagnosed, and undertreated due to inadequate treatment options. The development of additional treatments for OSA, such as pharmacotherapy, are critically needed. The collaboration between Regeneron and Sanofi are funding this project. Regeneron will be providing the drug and the contract will be with Regeneron. Both companies are involved as it is a collaboration across the companies.
This study aims to evaluate the accuracy of apnea detection and automated sleep analysis by the Dreem dry-EEG headband and deep learning algorithm in comparison to the consensus of 5 sleep technologists' manual scoring of a gold-standard clinical polysomnogram (PSG) record in adults during a physician-referred overnight sleep study due to suspicion of sleep-disordered breathing.
Extensive Prospective validation study of the NightOwl, a Type IV home sleep apnea test (HSAT), compared to traditional PSG and HSAT monitors.
The purpose of this study is to evaluate the relationship between DME and obstructive sleep apnea (OSA). OSA impacts millions of North Americans, many of whom are undiagnosed. The investigators aim to evaluate if a relationship exists between the two diseases, whether or not the severity of OSA impacts the severity of DME, and whether treating OSA results in better treatment outcomes for DME. The study will involve the standard of care provided for both DME (involving anti-VEGF injections) and OSA (involving continuous positive airway pressure [CPAP] machine).Approximately 150 subjects are expected to be enrolled in this study. In summary: Question 1: Is there a correlation between DME and OSA? Question 2: Is there a relationship between the severity of DME (CRT and vision) and OSA (AHI index)? Question 3: Does treating OSA result in improving DME metrics, and does it neutralize the outcomes at 1 year compared to OSA negatives.
Obstructive sleep apnea (OSA) is common and largely underdiagnosed disease. The standard method for the diagnosis of OSA is a complete night polysomnography (PSG). Simple methods for OSA diagnosis are necessary. The overnight oximetry with the oxygen desaturation index (ODI) has been largely investigated as a diagnostic test for OSA but its accuracy remains undefined. The aim of our study is to evaluate if an wireless polygraph (Oxistar) is accurate to diagnosis OSA in patients referred to a Sleep Lab.
Sleep apnea is common in acromegaly and both diseases are independently associated with hypertension and insulin resistance contributing to increased morbidity and mortality. Respiratory polygraphy is a simpler alternative to in-laboratory polysomnography for the management of more symptomatic patients with obstructive sleep apnea. The aim of this study is to evaluate the prevalence of sleep apnea by respiratory polygraphy, and to analyze the effect of transsphenoidal surgery on sleep apnea.
The majority of the elderly present with sleep apnea and mortality is significantly higher in this group. Sleep apnea runs the risk of developing diseases, especially hypertension and cardiovascular disease, while the Mediterranean diet is associated with reduced risk. No study evaluated the effect of the Mediterranean diet on the apnea and hypopnea index in the elderly. Therefore, the present work intends to evaluate the effect of the intervention with the Mediterranean diet on the apnea-hypopnea index in the elderly with moderate sleep apnea. The hypothesis study is that the elderly with moderately severe sleep apnea under a Mediterranean-type diet will modify AHI in the short term, regardless of weight change, due to changes in body volume and ingestion, especially those related to body water.
Sleep apnea is a prevalent problem and references for the evaluation of this condition often exceeds the sleep clinic's capacity thus creating important delays in the patients' care. The overall goal of this project is to assess the feasibility and the non-inferiority of integrating a clinical nurse, or supernurse, to the initial consultation team. The hypothesis is that the integration of a clinical nurse to the sleep clinic's evaluation team is non inferior in terms of patients' outcomes such as improvement of symptoms and quality of life as well as adherence to treatment. This study is supported by funding dedicated to teaching and research activities related to sleep-disordered breathing.
Postoperative pain is usually treated with opioids. Among them, oxycodone is popular in the daily practice as it is administered orally and is easily titrated. However, side-effects include increase duration and frequency of apneic episodes. Some authors believe that tramadol has less impact on these apneic episodes during the first postoperative night, based on a trial that reported conclusive results only during the first 2 postoperative hours. The objective of this randomized controlled trial is to compare the effect of postoperative pain treatment of oxycodone with tramadol on apneic episodes during the first and third postoperative nights.
