Filter by:The overarching goal of the research proposed here is to test the hypothesis (i) that the pathophysiological mechanisms of OSA lead to deterioration in sleep-dependent memory consolidation across memory systems, with the genetic marker APOε4 as a modulator, and (ii) that CPAP can reverse some or all of these measured memory deficits. In addition, we are exploring which aspects of OSA (e.g., changes in sleep architecture, measures of hypoxemia, or the EEG power spectrum) most likely impact sleep-dependent memory processing.To this end, we are using specific cognitive tasks for which sleep-dependent memory consolidation processes have previously been demonstrated by our group and others. In addition, we are carrying out quantitative EEG power spectral analyses, to delineate abnormal functioning of brain regions with more precision.
Targeted population: Sleep apnea patients at low cardiovascular risk newly treated by CPAP Hypothesis: Six months CPAP compliance might be greater in the telemonitoring arm compared to usual CPAP care. Main goal: To compare 6-months CPAP compliance when Sleep Apnea patients at low cardiovascular risk are randomly allocated to usual CPAP care or a multidisciplinary and coordinated follow-up based on a telemonitoring web platform.
Subjects referred to a sleep clinic had polysomnography (PSG), clinic BP measurements, 24-hour ABP monitoring and HBP monitoring using a device (Microlife WatchBP HomeN) that allows daytime (3 days, 2 duplicate readings/day) and automated nighttime BP measurement (3 nights, 3 readings/night).
The objective of the Study is to observe the use and utility of the Winx Sleep Therapy System in a clinical practice, for the treatment of patients with obstructive sleep apnea (OSA).
Randomized study of patients with primary snore, mild and moderate obstructive sleep apnea. Protocol include 40 patients randomized to oropharyngeal exercise or use of nasal dilator, breathing exercise and nasal lavage. The objectives are study the effects of therapy on oropharyngeal in a series of clinical and physiologic and anatomic variables, changes on snore and quality of sleep using Pharyngeal Critical Pressure, Magnetic Resonance, Negative expiratory pressure and snore analyses. Hypothesis that the therapy group (oropharyngeal exercises) will have more modifications compared to the control group.
The purpose of this study is to evaluate new iterations/generations of the ApniCure sleep therapy device.
The objective of this study is to assess the feasibility and safety of tongue suspension using the Siesta Medical Encore Tongue Suspension System for the treatment of obstructive sleep apnea (OSA).
The purpose of this study is to estimate the cost-utility of continuous positive airway pressure (CPAP) therapy in obstructive sleep apnea (OSA) patients in Sao Paulo city, Brazil, after 3 years of treatment and to estimate the cost-effectiveness of CPAP on the number of medical visits, hospitalizations, medical examinations, used medications, new case incidence and cost of traffic accidents and absence from work. It is also designed to estimate quality-adjusted extended years of life, and to assess cost-effects of the therapy (device, masks, supplies, maintenance/year for membership of professional consulting, electric power) on the cost-effectiveness
Not all patients with the Obstructive Sleep Apnea Syndrome (OSAS), mostly mild, have excessive daytime sleepiness. Sleep fragmentation provides the performance decrease with increasing reaction time to external stimuli and correlates with excessive sleepiness. So, the study aims at assessing the effect of sleep fragmentation on the Reaction Time and it`s maintenance in patients with OSAS compared with healthy, to better clarify were patients with and without somnolence differ. For that, will be recruited 30 male volunteers aged between 20 and 50 year old to participate in the study. They will be distributed in three groups: "CONTROL" (without symptoms of sleepiness and apnea and hypopnea index (AHI) less than 5), "SS" (with AHI between 5 and 15 without symptoms of somnolence) and group "CS" (with AHI between 5 and 15 with symptoms of somnolence). The groups will undergo a polysomnography and subsequently, the Test and Maintenance of Wakefulness and PVT Battery Tests. The reaction time will be compared, as well as the ability to keep the reaction time over time between groups to see whether there is a difference between the motor performance throughout the day and the perception of sleepiness.
Obstructive Sleep Apnea Syndrome (OSAS) is associated with stroke as a risk factor but little is known about the consequences of OSAS on the outcome and the survival after stroke. The aim of the investigators study is first to evaluate the outcome and the survival of patients with stroke depending of OSAS (presence and severity of OSAS) and second to compare the outcome and survival of patients with severe OSAS depending on the treatment of the syndrome with nocturnal continuous positive airway pressure. The investigators hypothesis is that OSAS is associated with worst survival and outcome and needs to be treated at the subacute phase of stroke.
