Filter by:The goal of this descriptive, cross-sectional survey design is to determine the effect of public awareness video on the basic knowledge regarding sleep apnea syndrome or glaucoma and traffic accidents in normal population The main questions it aims to answer are: - To assess the attitudes toward the health-related cause of traffic accidents, mainly focused on obstructive sleep apnea and glaucoma among Thai people who viewed the local language translated versions of the public awareness video. - To assess the feedbacks of the public awareness video. Participants will be ask to complete a set of questionnaires containing 3 parts - pre-test part - educational video part - post-test part
Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea(OSA) are common disorders ,the co-existence of both conditions is called overlap syndrome Smoking , obesity , airway resistance and inflammation are considered risk factors for both conditions ,interestingly either COPD and OSA are associated with increased cardiovascular complications with further increased risk in overlap syndrome Multiple theories could explain that one disorder can predispose or exaggerate the other. For example, in COPD cigarette smoking and inhaled steroids are linked to myopathy of upper airway dilator muscles. Moreover in core-pulmonale redistribution of edema fluid in supine position during sleep can also contribute to or exacerbate OSA . On the other hand , OSA patients might smoke frequently and more heavily to compensate for excessive daytime sleepiness and to help them to lose weight , which results in exaggerated airway inflammation and exacerbate COPD. Rationale of the study was to assess the prevalence and predictors of OSA among patients with stable COPD.
The main purpose of this study is to test is mandibular advacenment device (MAD) use is associated with reductions in nocturia.
This prospective observational study will enroll 60 moderate-to-severe OSA patients (AHIā§15/hour, 30 obese [BMI>=27] & 30 non-obese [BMI<27]) and 40 age-, gender-, BMI-matched controls without OSA. Venous blood 10 ml will be collected to isolate neutrophils, which are later tested for their ability to produce neutrophil extracellular traps (NETs) under the effect of PMA (phorbol 12-myristate 13-acetate). The test will be repeated if OSA patients receive CPAP therapy (continous positive airway pressure therapy).
Respiratory physiology involves a complex interplay of elements including control of breathing, respiratory drive, pulmonary mechanics, distribution of ventilation and gas exchange. Body position may also play an important role in respiratory mechanics. While effective methods exist for measuring these variables, they are typically measured in isolation rather than in combination. In pulmonary disease, decreasing mechanical stress and strain and optimizing transpulmonary pressure or the distending pressure across the lung, minimizing overdistention and collapse are central to clinical management. Obesity has a significant impact on pulmonary mechanics and is a risk factor for obstructive sleep apnea (OSA). However, our understanding of these elements is limited even in the general population. The investigators plan to use various validated methods to assess control of breathing, respiratory drive, distribution of ventilation and gas exchange to obtain a better understanding of underlying physiologic signatures in patients with and without obesity and the role of posture/position, with a secondary analysis comparing participants with and without obstructive sleep apnea.
The REMAP study aims to follow a cohort of 400 patients in around ten sleep centers in France and to collect clinical routine data. The objectives of this study are to investigate the effects of one-year management of OSA by CPAP or MAD on sleep architecture defined by objective macro and micro sleep architecture parameters using a sleep test device. sleep connected at home, to assess the quality of sleep and the quality of life reported by patients. The study will also allow us to define predictive factors for improving sleep quality during OSA treatment.
To verify the effect of orofacial myofunctional therapy in patients with OSA during the use of CPAP with a nasal mask, on the frequency and leak flow. In addition, the impact on mouth opening frequency, sleep quality, perception of excessive daytime sleepiness, and CPAP adherence will be evaluated.
The TUCSON study is a cross-sectional observational monocentric study. In order to provide a clinical helpful assessment for urologists for possible missed causes of nocturia, the aim is to investigate the voiding and sleep pattern through questionnaires and sleep and voiding diaries of patients consulting the urology department, sleep clinic and pneumology department. An assessment of the prevalence of missed underlying causes will be made and a subset of patients will be asked to deliver urine samples from every night time and first morning void to further investigate possible differences in urine content between the groups. First of all, with this research the aim to offer an idea about the order of magnitude for missed underlying causes of nocturia. Secondly, to discover a specific sleep and voiding pattern for the different entities of nocturia and thirdly, to offer a useful screening tool for underlying pathology in clinical practice.
This study intends to investigate the improvement in patients with OSA through objective measurement, including oxygen desaturation index (ODI) and the percentage reduction in intermittent mouth puffing (IMP) before and after the intervention. The oral appliances are placed between the tongue and the soft palate to reduce the oral ventilation space. A total of 24 participants aged between 36 and 57 years were identified with ODI above 5 events/hour by measuring their blood oxygen and with an originally designed mouth puffing detector to find out those who were still mouth-puffed when their mouths were taped. A suitable appliance was chosen for the participants between the two originally designed oral appliances, tongue pressed device (TPD) and tongue elevated device (TED), and the intervention lasted for six weeks.
This study is being done to understand body's response to hybrid home-based and on-site rehabilitation program utilizing individually tailored exercises throughout a total of 18 sessions with 12 of them occurring onsite, in people with and without chronic respiratory diseases, such as Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA) and in individuals recovered from COVID-19. Exercise training programs vary widely for people with COPD, OSA, and during prolonged recovery from COVID infection. This study will help identify if this program is helpful to address muscle loss and fatigue specifically in populations with and without chronic respiratory diseases.
