Filter by:Presently, there isn't any international recommendation to evaluate vigilance in Obstructive Sleep Apnea Syndrome. The French Society of Sleep Research and Medicine (SFRMS) recommend evaluating professional driver with a MWT but no recommendation exists for other patients. After a minimal treatment of 4 weeks, the physician has to evaluate the drowsiness risk of these patients using either an objective test like the MWT or a subjective one. In the university hospital Amiens-Picardie, since the 01/01/2015, every patient with an Obstructive Sleep Apnea Syndrome diagnosed by a polysomnography or a ventilatory polygraphy had a MWT after 4 weeks of treatment. At each time of the evaluation, Epworth Sleepiness Scale, tiredness score of Pichot, and depressive score of Beck are performed.
This study evaluates different factors that determine the treatment choice and treatment compliance in patients with central sleep apnea. All patients will receive routine care (registry).
This investigation is a prospective, non randomized, non blinded study. This investigation is designed to evaluate the performance, comfort and ease of use with the F&P trial nasal pillows mask amongst Obstructive Sleep Apnea (OSA) participants.
The links between obstructive sleep apnea syndrome (OSAS) and type 1 diabetes (T1D) are poorly studied. This study proposes to evaluate the severity of cardiovascular autonomic neuropathy (CAN) related to T1D in case of associated OSAS. This issue has significant diagnostic and therapeutic implications because of the increased cardiovascular risk in case of confirmed CAN in T1D patients.
The aim of this study in subjects with obstructive sleep apnea is to investigate pharmacodynamics, safety and tolerability after a single nasal administration of BAY2253651 and to evaluate first safety and tolerability of multiple dosing over 5 consecutive nights in OSA patients.
Obstructive sleep apnea (OSA) has been known as a risk factor for coronary artery disease, heart failure, cerebrovascular accident and atrial fibrillation. One study reported that patients with OSA have more atherosclerotic plaque burden in intravascular ultrasonography examination. Among patients who admitted with acute myocardial infarction (AMI), 65.7% (69 of 105) patients were diagnosed with OSA. Other long-term follow-up study revealed that 45.4% of patients (594 of 1311) who performed percutaneous coronary intervention (PCI) were diagnosed with OSA. Moreover, the OSA group was a significant independent predictor of major adverse cardiac and cerebrovascular events (MACCEs). Polysomnography (PSG) is the gold standard for the diagnosis of OSA. But, PSG is expensive, time-consuming and difficult to perform immediately. Recently, a portable device named WATCH-PAT (Itamar Ltd, Israel) was developed for the diagnosis of OSA. Validation study demonstrated a high correlation between WATCH-PAT and PSG in apnea-hypopnea index, lowest oxygen saturation and sleep time. This result suggested WATCH-PAT can be performed as an alternative or supportive device of PSG. WATCH-PAT. The portable device also can be useful to detect OSA in bus drivers who can be the reason for public traffic accidents. Moreover, WATCH-PAT can be applied to assess postoperative improvement of OSA. Although OSA is known as one of the risk factors for cardiovascular disease, there is a lack of evidence to recommend of the evaluation of sleep disorder in patient with coronary artery disease. Awareness and compliance for OSA are very low in both patients and cardiologists. Active diagnosis and treatment are definitely needed. Therefore, the primary endpoint of this study is to evaluate the prevalence of OSA in AMI patients who treated PCI. The secondary endpoint is to evaluate the 1-year incidence rate of MACCEs according to the presence or absence of OSA.
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) syndrome affects 40-60% of patients presenting with cardiovascular diseases. Cheyne-Stokes respiration is a type of central apnea characterised by the presence of at least three consecutive episodes of apnea and/or hypopnea separated by a crescendo-decrescendo variation of the breathing amplitude with a cycle length ≥ 40 seconds and a central apnea/hypopnea index ≥ 5/h, for at least two hours of recording. The association between heart failure and Cheynes-Stokes respiration is known and a recent study showed that Cheynes-Stokes respiration was associated with more severe heart failure. Moreover, a medical and medical/financial benefit of the early detection of cardiac decompensation has been reported. The purpose of this feasibility study is to investigate the benefit of Cheyne-Stokes respiration remote monitoring in CPAP-treated patients with OSA for the early detection of significant cardiac events (heart failure, rhythm disorder, diastolic dysfunction). To achieve this aim, a modified approach of CPAP remote monitoring is proposed based on the performance of the latest generation of positive pressure devices from ResMed, AirSense™ 10 Autoset™, which can detect and record the presence of Cheynes-Stokes respiration. For a period of 12 months, in addition to the usual daily remote monitoring (CPAP adherence, pressure settings, level of air leakages), the healthcare provider will systematically monitor the CSR data whenever the AHI increases significantly. Physicians will be alerted when a CSR occurs and they will see the patients within a short time for pulmology and cardiology consultations in order to screen the onset of significant cardiac event. After the 12-month period of modified remote monitoring, the telemedicine returns to the usual procedure. Patients who had at least one CSR occurrence during the first 12-month period will be followed up to 24 months to assess their medical condition.
Obstructive sleep apnea (OSA) is a clinical condition characterized by the repetitive obstruction of the upper airway during sleep, resulting in nocturnal hypoxaemia and fragmented sleep. Fragmented sleep leads to daytime sleepiness that causes alterations in reaction times and reflexes . Postural stability is an important function of the human body. It is shown that the sleep deprivation disturbs daytime postural stability and balance. Aim of this study is to examine the influence of OSA severity and daytime sleepiness on postural stability, balance and fall risk.
The investigators seek to understand how the different underlying causes of OSA affect the way people living with HIV (PLWH) experience OSA. The investigators also want to understand how symptoms of obstructive sleep apnea improve with treatment, and if this too, is affected by the underlying cause of OSA in that individual
