Filter by:The aim of the study is to evaluate the impact of CPAP treatment on asthma control in patients with severe uncontrolled asthma and obstructive sleep apnea (OSA)
This observational study aims to evaluate multiple dimensions of health in patients with Obstructive Sleep Apnea Syndrome (OSAS), before and after three weeks of ventilotherapy. Specifically, the study aims to identify pre- vs post-treatment differences in the following domains: - cognitive performance - blood expression of biomarkers related to neurodegeneration - psychosocial wellbeing Thus, patients will complete the following evaluations before (T0) and after (T1) ventilotherapy: - neuropsychological standard assessment - blood sampling - psychosocial self-reported questionnaires
This is a randomized controlled trial (RCT) of 4 weeks of study supplement N-acetylcysteine (NAC) versus placebo in persons with significant obstructive sleep apnea (OSA) who are receiving positive airway pressure therapy (PAP), the standard of care therapy. The purpose of the study is to determine if NAC is associated with sex-specific changes in overnight oxidative stress, inflammation, as well as endothelial dysfunction in persons with OSA.
This study aims to compare the effectiveness of conventional oxygen therapy oxygen and high-flow nasal cannula therapy on oxygen saturation (SpO2), measuring number of SpO2 drop >4% of base line oxygen saturation (o2 desaturation index), length of the ICU stay, and the need of use supplemental continuous positive airway pressure (CPAP) support in any of the study groups in the postoperative ICU setting.
This study will recruit 66 patients with obstructive sleep apnea, comprising 33 men and 33 women, who have been referred to the sleep center by their doctors for polysomnograms (PSG). The subjects will undergo two overnight sleep PSG sessions at the sleep center. The interval between the two examinations will be at least 7 days, during which they will receive both a placebo and medication conditions, administered 1 hour before bedtime. The study drugs will include: (1) atomoxetine 80 mg and oxybutynin 5 mg; or (2) venlafaxine 37.5 mg; or (3) atomoxetine 80 mg and trazodone 100 mg. Endotypic traits will be estimated using the Phenotyping Using Polysomnography method. The primary outcome is the change in apnea-hypopnea index, and secondary outcomes include endotypic traits and sleep parameters.
The CDC describes Post-acute sequelae of SARS-COV-2 infection (PASC) for the wide range of physical and mental health consequences experienced by some patients. These sequelae may be present four or more weeks after SARS-COV-2 infection, including patients who had initial mild or asymptomatic acute infection. However, there is complete absence of data whether chronic sleep changes due to COVID-19 infection may influence these physical and mental health consequences. While fatigue is one of the common post-COVID conditions, there are no systematic examinations of sleep disturbances in COVID-19 survivors. This will be a pilot observational retrospective and prospective cohort study, to systematically assess if sleep disturbances and severity of sleep apnea comprise a modifiable facet of PASC as well as the short-term and longer-term effects of COVID-19 infection itself on sleep, cognitive function, exercise capacity and lung function.
The goal of this study is to compare two continuous positive airway pressure (CPAP) settings on heart and lung function in patients with severe obesity after anesthesia. The main questions it aims to answer are: 1. Does a recruitment maneuver and CPAP set to intrathoracic pressure (ITP) improve cardiopulmonary function compared to standard CPAP settings in patients with severe obesity after anesthesia? 2. Does the location of adipose tissue influence the response to CPAP settings in patients with severe obesity after anesthesia? Participants will undergo monitoring of their intrathoracic pressure using an esophageal catheter. In the recovery area after anesthesia, participants will receive two CPAP settings, each for 20 minutes. - Intervention 1: Recruitment maneuver and CPAP will set to the level of intrathoracic pressure - Intervention 2: CPAP set to home settings (if OSA is present) or between 8-10 cmH20 (if OSA is not present).
The diagnosis of obstructive sleep apnea-hypopnea syndrome in children (OSAS) requires a polysomnography (PSG) in a sleep lab with video surveillance and monitoring by a nurse. But PSG is a cumbersome exam, sometimes difficult to perform in children. Simplified exams as respiratory polygraphy (RP) which uses only respiratory signals can be used for the diagnosis of OSAS but studies show that it underestimates the obstructive apnea-hypopnea index (OAHI) because the total sleep time cannot be accurately estimated. The use of a video camera with software synchronous with the RP software could compensate for this disadvantage, by estimating when the child is sleeping or not.
Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. Some OSA patients with low arousal threshold wake up prematurely during an obstructive event and do not have time for spontaneous upper airway (UA) dilator muscle recruitment. As a consequence they are exposed to apnea and hypopnea cycling. In this protocol the investigators will test the effect of trazodone administered before sleep on OSA traits and OSA severity during sleep.
This study included 90 volunteer Obstructive Sleep Apnea Syndrome patients. Only 7 mL blood samples collected from patients. Some biochemicals parameters analyzed in blood serum/plasma.
