Filter by:Introduction: Obstructive sleep apnea syndrome (OSAS) is a condition characterized by recurrent episodes of partial or complete obstruction of the upper airway (URI) during sleep. Objective: It was designed to compare the effects of aerobic and high-intensity interval training training on exercise capacity, fatigue, cognitive status, physical and disease-specific parameters in individuals with obstructive sleep apnea syndrome. Materials and Methods: It was designed as a randomized controlled experimental model. Patients between the ages of 18-55 who were diagnosed with OSAS by polysomnography by a specialist physician, and those with moderate (AHI: 16-30) and severe (AHI> 30) OSAS will be included. After the patients were selected from the relevant population with the improbable random sampling method, the patients who accepted to participate in the study and met the inclusion criteria will be assigned to one of the aerobic exercise group, high-intensity interval training training group or control group with the closed-envelope method. Evaluations will be evaluated for each group before the first session of the exercise program and one day after the last session after they have completed the 8-week exercise program. Evaluation parameters; 6-minute walk test, fatigue severity scale, stroop test, skinfold, tape measure, comprehensive respiratory function test device (MasterScreen™ Body Plethysmography), Turkish version of the functional outcomes of the disease-specific quality of life sleep questionnaire (functional outcomes of sleep questionnaire, FOSQ,tr) The nottingham health profile includes the Epworth sleepiness scale. Conclusion: The effects of aerobic and high-intensity interval training training will be interpreted by comparing the evaluations before and after treatment and between groups.
The purpose of this study is to evaluate the effect and safety of tirzepatide in participants with obstructive sleep apnea and obesity who are both unwilling or unable to use Positive Airway Pressure (PAP) therapy in GPI1 and those who are and plan to stay on PAP therapy in GPI2.
Obstructive sleep apnoea (OSA) is the most serious kind of the sleep-disordered breathing group, characterised by recurrent episodes of partial to complete obstruction of the upper airway resulting in inefficient alveolar gas exchange and desaturation[1]. It is a commonly encountered condition with a reported prevalence of 9-25% in the general population [2]. However, the majority of OSA patients presenting for surgery remain undiagnosed or untreated[3], contributing to a high rate of unexpected adverse airway outcome[4]. The various airway abnormalities represented by OSA include a large tongue, collapsible airway and crowding of the oropharyngeal structures, among others[5]. Accurate airway assessment should always be performed so as to provide appropriate planning and management of expected difficult intubation, but the common clinical screening tests (Mallampati score, inter-incisor distance, mento-hyoid distance, BMI, etc ) have shown low sensitivity and specificity with a limited predictive value, especially if only a single assessment method is used[6]. Ultrasonography could be a highly sensitive and specific tool for prediction of difficult intubation in OSA patients presented for elective surgery by measuring tongue base thickness, distance between lingual arteries, hyo-mental distance and condylar mobility.
The main objective is to evaluate the overall effectiveness of MAD therapy as a first line treatment, including both efficacy in terms of reduction in OSA severity as well as objective compliance, in patients recently diagnosed with moderate to severe OSA, waiting for a new CPAP device. Upon completion of MAD-therapy, patients will be put on CPAP, allowing for comparison of MAD effectiveness versus the overall therapeutic effectiveness of CPAP therapy in the same patient. Finally, patients' preference for either therapy will be evaluated.
Obstructive Sleep Apnea (OSA), a common disorder resulting from repetitive pharyngeal collapse during sleep, is multifactorial. Usually, OSA is considered primarily a problem of upper airway anatomy, with the craniofacial structure or neck fat decreasing the size of the pharyngeal airway lumen. Obesity, male sex and genetics are well established pathogenic factors. In the last decade rostral fluid displacement (fluid shift) to explain the pathogenesis of upper airway collapsibility has been increasingly studied. Individuals living with spinal cord injury are at increased risk for OSA, with a prevalence that is three- to fourfold higher than the general population. Individual with acute tetraplegia and undiagnosed or untreated OSA may participate less in rehabilitation due to sleepiness and fatigue and therefore be less engaged in activities that improve quality of life and maintain functioning over time. Intermittent hypoxia, sleep fragmentation and alterations of the autonomous nervous system induced by OSA are thought to delay or limit recovery and in the long term, increase cardio- and cerebrovascular morbi-mortality. Redolfi et al have shown that overnight change in leg fluid volume correlated strongly with the Apnea Hypopnea index (AHI) and the time spent sitting. In SCI patients two mechanisms may underline fluid shift importance in the pathogenesis of OSA: first, time spent sitting is obviously increased in patients with no walking abilities (prolonged sitting position in wheelchair). Secondly, motor deficit lead to the loss of skeletal muscle pumping activity which could promote leg fluid accumulation during the day. In our knowledge, no study has specifically assessed the impact of rostral fluid displacement on upper airway collapsibility among patients with spinal cord injury. Better comprehension of upper airway collapsibility determinants in patients with spinal cord injury is mandatory to identify new therapeutic targets (diuretics, contention…) especially since CPAP, the first line treatment for severe OSA, continue to pose adherence issues in SCI patients. In the future, phenotyping OSA patients, especially those with SCI, will improve personalized management. The main objective is to find if there is a correlation between the apnea-hypopnea index (AHI) and rostral fluid shift overnight, in non-obese spinal cord injured patients. The secondary aim is to find if there is a correlation between AHI and: - Neck circumference - Neck volume - Time spent sitting down
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.
Obstructive sleep apnea (OSA) is a type of disordered breathing defined by the repetitive obstruction of airflow during sleep due to upper airway collapse. Each obstructive event contributes to decreased blood oxygen, or hypoxia. OSA has been associated with various cardiovascular diseases, including hypertension, stroke, heart failure, and coronary artery disease. A factor in this association may be the decrease in blood vessel health and the marked over activation of the sympathetic nervous system that is observed in OSA due to nighttime hypoxia. The sympathetic nervous system is responsible for maintaining heart and blood vessel (cardiovascular) balance. Elevated sympathetic nervous activity (SNA) is a likely cause of hypertension and subsequent cardiovascular disease. Continuous positive airway pressure (CPAP) therapy is the most accepted treatment for OSA and has been shown to improve high blood pressure and SNA in patients. An alternative therapy for OSA is a type of removable oral appliance known as a mandibular advancement device (MAD). Currently, there is no research directly measuring SNA in OSA patients using MADs. In addition to other cardiovascular markers, the investigators would like to directly assess SNA during a MAD intervention using the gold standard technique of microneurography. The investigators believe this will provide important information for the management of OSA, as levels of SNA are known to respond to both acute and chronic levels of hypoxia. Improved heart and blood vessel markers could further support MAD use, providing an important alternative therapy for those that can not tolerate CPAP.
Multicentric, prospective, opened study to evaluate the impact of Health Literacy Levels on CPAP withdrawal in Obstructive Sleep Apnea patients within 6 months of inclusion.
This clinical trial will compare home sleep apnea testing with the gold standard in-lab polysomnography in terms of 1) accuracy, 2) therapeutic decision-making, and 3) parent/child acceptability in children referred for evaluation of obstructive sleep apnea.
MIST+ is studying a nasal spray to see if it will reduce the need for surgery for snoring. Children aged 3-12 are invited to take part. Snoring affects up to 10% of children and can cause sleeping problems and concentration or behavioural issues in the daytime. Currently the most common treatment for snoring is surgery to remove the tonsils and/or adenoids, however many children wait a long time to see a specialist. This research is trying to find if nasal sprays can help children with snoring, and whether this can reduce the need for surgery.
