Active clinical trials for "Sleep Apnea Syndromes"

This study aims to determine whether the risk for sleep-disordered breathing in infants with myelomeningocele (a severe form of spina bifida) differs among those who underwent fetal vs. postnatal surgery, and to examine the link between sleep-disordered breathing and neurodevelopment.

Sleep apnea is a common disease in the general population and more particularly in elderly subjects in whom prevalence can reach 30 % after 70 years old. In adults (<55 years old) cardiovascular consequences are well known and make sleep apnea treatment necessary. However elderly (>70 years old) apneic subjects are less symptomatic in terms of sleepiness, they usually present a lower index of respiratory events and cardiovascular consequences in this population are still discussed, driving some authors to consider sleep apnea in the elderly as a specific disease and making the need for a treatment questionable. In this study the investigators will focus on the comparison between adult and elderly apneic subjects in terms of cognitive and cardiovascular consequences. Adult apneic patients suffer from a decrease of cognitive performance as well as grey matter local atrophy, particularly in the hippocampus and in the frontal lobes. According to fewer studies, white matter can also be affected by a demyelinisation process. These structural modifications are sometimes associated with disorders of executive and memory functions. In the elderly, no clear association can be drawn between cognitive decline and sleep apnea. Moreover, to our knowledge, the cerebral state of elderly symptomatic apneic subjects has mostly not be investigated.

The main objective of the study is to identify the determinant of sleep characteristics of obese patients attempting a tertiary clinical center for obesity management, including bariatric surgery. More accurately the questions addressed are: What are the determinants of the sleep habits (sleep duration, chronotype) and of their evolution What are the determinants of sleep breathing disorders (sleep apnea, obesity hypoventilation syndrome) and of their evolution

TELEAP1 is a multicenter cohort pilot-study designed to evaluate the impact of a published SFRMS/SPLF CPAP-telemonitoring diagnosis/therapeutic algorithm on the CPAP-compliance of newly treated patients with obstructive sleep apnea..

Background: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) is the most common periodic fever syndrome of childhood. Symptoms can include swelling of the glands in the throat, mouth ulcers, and tonsillitis. Removal of the tonsils can stop the periodic flareups. But researchers do not know how PFAPA develops. In this natural history study, researchers will collect specimens and data from people with PFAPA to see what they might have in common. Objective: To collect blood and other specimens from people with PFAPA to learn more about the illness. Eligibility: People aged 1 month or older with symptoms of PFAPA or another tonsil disorder. Design: Participants will be screened. Their medical records will be reviewed. Researchers will ask about a family history of PFAPA. The following specimens may be collected: Blood. Blood will be drawn either from a needle inserted into a vein or from a prick in the finger or heel. Mucus and cells. A stick with soft padding on the tip may be rubbed inside the nostrils or mouth. Stool. Saliva. Tissue samples may be taken if participants are having surgery to remove the tonsils or adenoids. Participants having surgery may also have a nasopharyngeal wash; salt water will be squirted into the back of the throat and then sucked back out with a syringe. Most participants will provide specimens only once. They can do this in person at the clinic; they can also have their local health providers send specimens to the researchers. Some participants may have optional follow-up visits over 10 years.

Heart Failure is a disease involving many different aspects of the human body, including changes in metabolism, the way the body produces and uses energy. Research shows that patients with heart failure often have a sleep disorder called sleep disordered breathing (SDB). It has been shown that SDB is associated with poor outcomes in heart failure patients, but the exact reason is unknown. It is likely that SDB leads to changes in metabolism and hormone status in the body, which is especially dangerous for heart failure patients. There is currently no treatment for SDB in heart failure patients. Recently, with Sodium glucose co-transporter 2 (SGLT2)-Inhibitors a new drug class has been approved for the treatment of advanced heart failure. This drug has effects on the metabolism in heart failure patients, among several other effects. This research project has the aim to investigate if SGLT2 inhibitors can help in the treatment of SDB, as many mechanisms of the drug overlap with the mechanisms how SDB develops. The drug has been approved by the FDA for the treatment of heart failure. The investigators want to study the effect of the drug on SDB by using a home sleep test called Watchpat, which has been approved to diagnose SDB.

A prospective double blind, placebo-controlled, randomized cross-over trial to evaluate the effect of lowering cerebral blood flow on the ventilatory chemoreflexes (acute hypoxic and hypercapnic ventilatory responses).

Minimally invasive electrical stimulation of the nerve hypoglossal for the treatment of obstructive sleep apnea. To demonstrate the correct stimulation of the medial branches of the hypoglossal nerve and tongue protrusion using a minimally invasive implantation technique in patients with OSA.

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.

Aim 1: The Investigators will perform a cross-sectional study to examine vascular risk in individuals with OVS compared with matched individuals with OSA alone or COPD alone. The PI will examine a panel of biomarkers including cardiac magnetic resonance imaging (right ventricular mass primary outcome), flow mediated vasodilation, plasma biomarkers (BNP, troponin, hsCRP, ST2, galectin3, miR-210). This aim will allow the team to test the hypothesis that individuals with OVS have increased vascular risk compared with matched individuals with OSA alone or COPD alone. This aim will also allow the team to compare the magnitude of the effect of OSA vs. COPD vs OVS for design of subsequent basic and clinical studies. Aim 2: The Investigators will perform an interventional study in individuals with OVS to compare the impact of bi-level therapy with that of oxygen therapy (the current standard of care). The team will assess the same panel of biomarkers as in Aim 1 to determine the impact of treatment on the observed abnormalities. This aim will allow the team to test the hypothesis that bi-level therapy is superior to oxygen in the treatment of individuals with OVS from the standpoint of right ventricular mass and other cardiovascular risk parameters/outcomes. Our assessments of biomarkers will help to define potential causal pathways for our findings and will allow determination of appropriate biomarkers for subsequent multicenter studies.
