Obesity Hypoventilation Syndrome(OHS) is characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. It is stated that obesity is at the basis of the metabolic changes seen in individuals diagnosed with OHS. Also sedentary lifestyle habits, which are common in obese individuals, cause the risk of sarcopenia due to loss of muscle strength and mass, accumulation of adipose tissue in the body, and decreased exercise capacity. Reduced exercise capacity due to obesity has been shown in the literature to strongly interact with mortality risk. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Simultaneously, sleep parameters are also negatively affected. In particular, increased adipose tissue leads to loss of muscle mass and strength, increased risk of sarcopenia and sleep-related problems. The association of obesity and sarcopenia is referred to as 'sarcopenic obesity'. Sarcopenic obesity is defined as the coexistence of sarcopenia and obesity. The concept of sarcopenic obesity has recently taken its place in the literature. In particular, there are very few studies on its relationship with sleep parameters. However, while obesity is the basis of OHS, there are no studies on the presence and effects of sarcopenic obesity in this patient group. Based on this point, we aim to investigate the effects of sarcopenic obesity on sleep parameters, exercise capacity and quality of life in individuals with OHS.
NCT04992676
The purpose of this research is to determine how frequently sleep disorders such as sleep disordered breathing and insomnia occur in patients with coronary artery disease enrolled in cardiac rehabilitation. By reviewing results of a variety of tests, we also hope to learn more about the cardiovascular effects on people who may have these conditions.
NCT04133350
This is a prospective, single-arm, unblinded pilot study and registry that aims to demonstrate adherence to adaptive servo-ventilation (ASV) therapy in patients with moderate to severe sleep disordered breathing who have been recently hospitalized. ASV therapy has been linked to improved outcomes in this population, but adherence to therapy is low. The AirCurve 10 ASV device that will be used for this study employs newer technologies, such as web-based monitoring and provides patients feedback, which may increase therapy adherence and therefore improve patient outcomes.

Obstructive sleep apnoea (OSA) is characterised by recurrent nocturnal respiratory interruptions, resulting from the total or partial collapse of the upper respiratory ways. This results into sleep fragmentation, metabolic and biological disorders, which alter the neuropsychological and cardiovascular systems. Nowadays, 24% of men and 9% of women aged 30 to 60 years disclose already an asymptomatic and underdiagnosed sleep disorder breathing (SDB). In subjects suffering from cardiovascular disease, prevalence of SDB is higher than in the general population, reaching 87% in people with resistant hypertension, 51% in those with heart failure and 62% in those with atrial fibrillation (to cite a few).The current diagnostic tool for SDB is polysomnography (PSG), but this is an expensive, time-consuming and uncomfortable tool, which limits its wide-spread use despite the high frequency of SDB in general and, even more, in patients suffering from cardiovascular diseases. Several screening devices exist in order to test those patients at risk of SDB, but these have several limitations, since they are not recommended in patients who are asymptomatic for apnoea, in those with cardiorespiratory diseases, nocturnal arrhythmias or neurological and metabolic co-morbidities. In other words, nowadays there isn't an efficient screening tool of SDB, mainly for those with a low pre-test probability of having SDB. Preliminary evidence suggests that the seismocardiography (SCG) and the ballistocardiography (BCG) can detect nocturnal awakening and sleep disturbances with a good sensitivity and accuracy as compared to the state-of-the-art PSG. Simultaneous recording of SCG and BCG is called kinocardiography (KCG) and has not been performed yet during sleep. The main hypothesis tested in this study is that the KCG provides sensitive and accurate measures of obstructive and central apnoea as compared to the state-of-the-art PSG. The secondary hypotheses are related to modifications in the SCG and BCG signals during the apnoea and the effects of continuous positive air pressure (CPAP) therapy. These hypotheses will be tested through a series of studies in normal volunteers and patients, as follow: * Group RESPIRATOIRYSIMUL (Study A): voluntary end-expiratory breathing cessations periods and obstructive voluntary apnoea's (n=46); * Group SBD (Study B): patients admitted for complains of sleep disturbances without cardiovascular and/or respiratory abnormalities which could induce artifacts in the KCG recording (n=50); * Group nCPAP (Study C): patients treated by nCPAP therapy (n=50); * Group UNSELECTED (Study D): unselected consecutive patients (n=100), without recruitment restrictions. Study A is an interventional study on voluntary breath holding in normal volunteers. Studies B, C and D are observational investigations recruiting subjects referred for PSG as required by their medical condition. Because the KCG device is not intrusive, the investigators do not anticipate difficulties in the enrollment. This study will not affect in any manner the regular medical care of the patients admitted to the sleep laboratory. To conclude, SDB is a widespread disease with detrimental health effects and its prevalence is supposed to increase in future years. PSG is the gold standard for diagnosis of SDB but it is an expensive, uncomfortable and time-consuming tool, limiting its use in daily clinical practice. For subjects with a high pre-test probability of SDB, portable, inexpensive and easy-to-use tools have been proposed as sleep monitoring and seem to provide accurate estimates of SDB. Although such devices seem promising, they disclose also several limitations and are not universally accepted as SDB screening devices, mainly in case of low pre-test probability of SBD. The less cumbersome KCG may screen patients for SDB accurately. One of its unique features is also that it can directly identify the consequences of SDB and nCPAP therapy on the cardiovascular system, and in especially the presence of frequently associated cardiac arrhythmias. With a more efficient pre-screening, those who are most likely to be eligible for nCPAP therapy will have a better access to the currently existing sleep laboratory facilities. The present research project has thus the potential of improving SDB patients care and health, at no additional societal costs.

Subjects who consent to participate in the research will undergo a simultaneous recording of inlab PSG and WatchPAT200 for comparing the WatchPAT data to PSG at an altitude of 8500'.
NCT03067103
Adenotonsillectomy is one of the most common ambulatory surgical procedures performed to children. Tonsillectomy or adenotonsillectomy have a high incidence of postoperative pain. There is still debate about the optimal analgesia for this common surgical procedure. Different methods have been described and used to reduce pain including; improved intraoperative anesthetic pain regimens, use of corticosteroids, adjustment of surgical technique, and intraoperative local anesthetic injection. Intraoperative local anesthetic is a preventive or preemptive analgesia which is the analgesia given before painful stimuli to prevent the subsequent pain. The main goal of the preventive analgesia is the pain relief with minimum side effects. The role of local anesthetic infiltration in the reduction of postadenotonsillectomy pain is still controversial. The objective of this study is to investigate and compare the effectiveness of preincisional peritonsillar infiltration of ketamine and tramadol for post-operative pain on children following adenotonsillectomy. This is prospective, double-blinded randomized study.
