Filter by:In this study respiratory and submental muscle activities during during inspiratory and expiratory breathing maneuver at specific workloads will be assessed according to inspiratory and expiratory muscle strength of each obstructive sleep apnea syndrome (OSAS) patient's.
assess the relationship between obstructive sleep apnea and endocrine, inflammatory, and metabolic bio-markers in consecutively enrolled adult male patients with a clinical suspicion of obstructive sleep apnea.
Obstructive Sleep Apnoea (OSA) is a sleep-related breathing disorder that is characterized by the repeated collapse of the upper airway during sleep, resulting in sleep deprivation. Mandibular Advancement Appliances (MAA) or Oral Appliances (OA) is prescribed for the patients with OSA and they have been shown to be effective. However, they rely entirely on the patient's acceptance and use. The aim of this study is to assess whether interventions- additional support approaches, will help patients use their MAA more as compared to those who receive routine care. The investigators also will try and identify factors that help us to understand why some patients choose to wear the MAA more than others. Adults (≥40 years) with a confirmed diagnosis of OSA (apnoea-hypopnoea index >5) and referred for MAA therapy will be included in this study. It is a multicentre study comprised of recruiting patients from secondary care. Patients will be provided with information in relation to the study and written informed consent obtained at their subsequent appointment for placement of MAA. Patients will be randomly assigned to Intervention Care (IC) and Standardised care (SC). Patients will also be provided with a sleep diary to subjectively record their hours of sleep and usage of MAA and an objective adherence record from the micro-sensor included in their MAA design. Data indicating adherence will be collected and evaluated, both subjectively at 3- (T2) and 6-months (T3) and objectively by downloading the data stored within a micro-sensor placed in the MAA device. At the end of the follow-up, the investigators also plan to undertake a qualitative one-to-one interview with patients compliant (users) and non-compliant (non-users) to identify their views of what helps and/or prevents their adherence.
The purpose of this study is to evaluate the safety and tolerability of administering a single intravenous (IV) infusion dose of TAK-925 to adults with obstructive sleep apnea (OSA) who are experiencing excessive daytime sleepiness (EDS) despite adequate use of CPAP as the primary OSA therapy.
This study evaluates the correlation of the position of the head during sleep, independent of the position of the torso, and the severity of apnea hypopneas in obstructive sleep apnea.
This study aims to evaluate the association between obstructive sleep apnea (OSA) and fetal growth restriction (FGR) and to assess the role of auto-titrated positive airway pressure (aPAP) as antenatal therapy in these patients. Pregnant patients with diagnosed FGR will be screened for OSA first by screening questionnaire and then by home sleep monitor. Of those patients diagnosed with OSA, half will be assigned to use aPAP each night when sleeping and half will not (standard care).
Assessment of the lung hyperinflation by bodypletysmography in patients with obstructive sleep apnoea treated with continuous positive airway pressure therapy.
Sleep-disordered breathing has a prevalence of 30~80% in patients with heart diseases. Various studies have revealed a correlation between the incidence and various diseases such as heart failure, hypertension, diabetes, and cerebral infarction. Postoperative acute kidney injury after heart surgery is one of the major complications with incidence with 40~50%, however, there has been no preventive method or treatment yet. Recently, several studies have been published that have shown a correlation between sleep-disordered breathing and renal impairment. In general, sleep-disordered breathing can be regulated easily with continues positive expiratory pressure, which means that early diagnosis and treatment of sleep-disordered breathing might help to reduce the incidence of postoperative acute kidney injury and improve patients' prognosis. In this study, the investigators investigate the impact of sleep-disordered breathing (diagnosed by oxygen desaturation index ≥5) on the incidence of postoperative acute kidney injury in patients undergoing valvular heart surgery.
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common childhood sleep disorder with an incidence of 3% . Studies have confirmed that OSAHS can cause multiple systemic dysfunction in children, especially affecting cognitive function . Cognitive function is an important part of human advanced neurological activities, including neurobehavioral functions such as orientation, attention, concentration, alertness, behavior, execution, etc., as well as intelligence and verbal functions such as memory, learning, calculation, language, understanding, judgment, and logic. Reasoning and many other aspects. Impaired cognitive function often means poor academic performance, which is the most concern of parents. However, due to the limitations of cognitive assessment tools, most studies only conduct qualitative research on children's cognition, lack of quantitative research. . The underlying reason is that these studies lack the guidance of systematic intellectual theory and the support of cognitive quantitative assessment tools. At present, no one at home and abroad has systematically and comprehensively studied the cognitive impairment caused by OSAHS based on the most advanced cognitive theory. Modern cognitive science believes that cognition, including human memory, decision, reasoning, classification, and planning, is an ability that can be added to "the treatment may change." Some skill and intelligence of human beings at a certain level of cognitive activity can be trained in the execution of certain practices and in the completion of a plan. Scenes, situational features, and tasks, whether material or symbolic, play an important role in human training techniques. Therefore, evaluable and scientific cognitive function training for individuals is beneficial to the development of cognitive function, especially for the treatment training of patients with cognitive dysfunction. At present, the treatment of OSAHS is mainly for the treatment of primary disease such as oropharyngeal surgery, CPAP, etc. These treatments
Obstructive sleep apnea (OSA) is a complex disease associated with repeated closure of the upper airway during sleep which causes excessive daytime sleepiness. Daytime sleepiness can affects daytime performance undesirably and reduces driving performance causing an increased risk for accidents. It can also lead to high blood pressure, strokes, and eventually death. Until now, there is no standardize value for the jaw advancement for the mandibular advancement appliance. It was found that when comparing the jaw advancement amount of 50% and above 50%, there is no additional efficacy. Efficacy of jaw advancement below 50% is lacking. Patients usually experience more complications with more advancement, there the investigators need to study the optimal mandibular advancement with least complication to the patients.
