Filter by:A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.
The primary aim of this study is to assess the relationship between obstructive sleep apnoea (OSA) and cardiac autonomic neuropathy (CAN) in patients with T1D. The secondary aims of this study are to assess: (1) the prevalence of OSA in patients with T1D; (2) the relationship between OSA and metabolic parameters (such as glycaemic control, blood pressure, lipids and weight) in patients with T1D; (3) the relationship between OSA and diabetes-related microvascular complications (retinopathy, nephropathy, peripheral neuropathy) in patients with T1D; and (4) the potential mechanisms for the relationship between OSA and diabetic-related complications if such a relationship is found.
The primary objective of the Sleep and Stent II is to determine the prevalence of REM-OSA in DM versus non-DM patients undergoing clinically indicated PCI. The secondary objectives are to investigate the association between REM-AHI and (1) cardiac arrhythmia based on ambulatory ECG monitoring, (2) excessive daytime sleepiness, and (3) glycemic control in patients with DM. In addition, we will determine the prevalence of REM-OSA based on alternative definitions, including (a) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2; (b) overall AHI at least 5 with AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 15; (c) overall AHI at least 5, AHI REM/AHI NREM ratio at least 2 and with AHI NREM < 8.
There is an unmet demand for the evaluation of nocturnal hypoventilation in children with NMD. An ambulatory screening tool that can reliably facilitate timely diagnosis and treatment in these children would be invaluable. If an ambulatory, at home, tcCO2 monitoring device is shown to be diagnostically accurate, sleep physicians would be able to triage children on existing waiting lists and optimize screening of nocturnal hypoventilation as recommended by international guidelines.
Obstructive sleep apnea (OSA) is a breathing disorder that is characterized by episodes of complete or partial cessation of respiration during sleep, associated with upper airway collapse, oxygen desaturation and sleep fragmentation. OSA is a condition frequently implicated in cognitive disturbances, as well as associated with health conditions such as hypertension, metabolic disturbances and heightened risk of heart disease, stroke and mortality. These conditions are also increased in persons living with HIV. Individuals suffering from OSA report an increase in daytime sleepiness, mood changes and decline in quality of life.OSA also portends economic and societal impact through lost productivity at work and motor vehicle accidents. The presence of OSA is therefore important to detect in those living with HIV as it is potentially treatable contributors to cognitive disturbances in HIV. Continuous Positive Airway Pressure (CPAP) is the recommended treatment of choice for OSA. CPAP has established efficacy in improving cognition (executive function, long-term verbal and visual memory, attention/vigilance and global cognitive functioning). Although CPAP has been associated with improvements in cognitive functioning in the general population, its effectiveness in improving cognition in HIV+ individuals has never been previously tested. Given that cognitive disturbances in this population are multi-factorial, determining whether treatment of OSA in this population improves cognition is key in improving the clinical management of HIV+ individuals, both for its negative impact on cognition, but also more generally for their health.
The purpose of the study is: 1) To assess the feasibility of unmonitored polysomnography and 2) to compare apnea hypopnea index (AHI), average SPO2, and SPO2 nadir between unmonitored polysomnography and in-laboratory polysomnography in pediatric patients.
This study will be conducted to determine whether lemborexant as compared to placebo decreases the peripheral oxygen saturation during total sleep time in healthy adult and elderly participants after a single dose of treatment and to determine whether it increases the apnea-hypopnea index after single and multiple doses of treatment in adult and elderly participants with mild obstructive sleep apnea (OSA).
This randomized prospective study aims to determine the effect of ketorolac on the total dose of morphine required to achieve postoperative analgesia in children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy. Participants will be randomly assigned to a study group where they will receive ketorolac in addition to the standard of care treatment or will receive only the standard of care pain management. The researchers hypothesize that by administering ketorolac at the end of the procedure once hemostasis has been achieved, it will be possible to decrease the amount of morphine administered in the post-anesthesia care unit (PACU). This study aims to provide a more comprehensive understanding of the efficacy and safety of the current standard post-operative analgesic regimen employed at the study institution, in which opioid analgesia currently plays a prominent role.
Obstructive sleep apnea (OSA) is a sleep-related breathing disorder, often associated with a compromised upper airway space and an increase in upper airway collapsibility. The anatomical and functional abnormalities of the upper airway play an important role in the pathogenesis of OSA. It is hypothesized that there is racial variation in the craniofacial characteristics among OSA patients. However, inter-race comparisons based on previous studies can be problematic due to variation in measurements, OSA definitions and the sample size. Besides, to our best knowledge, there is no studies that made direct inter-race comparisons in the upper airway anatomy. Therefore, studies on inter-race comparisons of the upper airway characteristics are needed to further understand the role of race in the upper airway anatomy of the OSA patients. This would provide more insights into the pathophysiology of OSA, and could result in the development of new effective treatment strategies for OSA patients.
This study investigates the differences between subjects with and without periodontitis in: the prevalence of (pre)diabetes mellitus, the risk of atherosclerotic cardiovascular disease, the prevalence of metabolic syndrome and the risk of obstructive sleep apnea syndrome.
