Filter by:The purpose of this study is to investigate the feasibility of sound analysis for: a) sleep apnea detection both during wakefulness and sleep, and b) flow-sound relationship during both wakefulness and sleep in patients and control individuals. The ultimate goal of our research is to simplify the current assessments for sleep apnea detection so that it is more convenient for patients and also much faster than the current techniques.
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.
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.
Shared decision-making helps patients to establish a treatment plan with clinicians together. Our goal was to determine if the tools we developed could reduced decisional conflict for patients with obstructive sleep apnea.
The investigators have established the "Evaluating the Alimentary and Respiratory Tracts in Health and disease" (EARTH) research program. It provides a structured approach to analysing gastrointestinal and respiratory microbiomes, along with diet and symptomatology, in children with a gastrointestinal and/or respiratory condition with recognised long-term morbidity (e.g. cystic fibrosis, obstructive sleep apnoea, or Hirschsprung's disease). The EARTH program consists of a series of prospective, longitudinal, controlled, observational studies, with each individual study comparing children with a chronic gastrointestinal and/or respiratory condition to healthy controls (HC). It will be conducted in an Australian tertiary paediatric hospital (although the methodology is applicable to other settings). Children with a chronic gastrointestinal and/or respiratory condition will be compared to age and gender matched HC across a 12-month period. The following will be collected at baseline, 6 and 12 months: (i) a stool sample, (ii) an oropharyngeal swab or sputum sample, (iii) a semi-quantitative food frequency questionnaire, (iv) details of disease symptomatology, (v) health-related quality of life, and (vi) psychosocial factors. Data on the intestinal and respiratory microbiomes and diet will be compared between children with a condition and HC. Correlations between dietary intake (energy, macro- and micro-nutrients), intestinal and respiratory microbiomes within each group will be explored. Data on disease symptomatology, quality of life and psychosocial factors will also be compared between children with a condition and HC. The investigators hypothesise that: (i) Children with chronic gastrointestinal and/or respiratory conditions will have altered intestinal and respiratory microbiomes compared to healthy children, and (ii) Diet plays a key role in influencing the intestinal and respiratory microbiomes and this may impact on clinical outcomes, biomarkers of disease, and health-related quality of life.
The primary objective of this study is to confirm the safety and clinical effectiveness of the Genio™ system, used according to its instructions for use, in moderate to severe Obstructive Sleep Apnea (OSA) adult patients over a period of 3 years post-surgery.
This trial will aim to test a new wearable device for the diagnosis of Sleep Apnoea.
Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults. Compared to the general population, OSA occurs more often in patients with coronary artery disease (CAD), with a reported prevalence of 38% to 65%. Emerging evidence indicates OSA initiates and exacerbates coronary atherosclerosis. Moreover, several observational studies indicate the presence of OSA was associated with higher rate of restenosis and repeat revascularization (mainly attributed non-culprit lesion revascularization) after percutaneous coronary intervention (PCI). OSA might initiate endothelial injury by repetitive bursts of sympathetic activity that occur with apneas and hypopneas. Moreover, untreated OSA reduces endothelial repair capacity. Whether OSA could exacerbate neointimal proliferation and plaque progression in the non-culprit lesion after drug-eluting stent (DES) implantation remains less studied. The investigators aimed to evaluate neointimal proliferation and strut coverage within stent segment as well as changes of plaque volume and morphology in the non-culprit lesion by optical coherence tomography (OCT) in patients with versus without OSA at 12-month follow-up.
This study aims to see if mobile video clips (smartphone recordings) can be used to screen children with Down syndrome to identify those at highest risk of obstructive sleep apnea (OSA), so they can be prioritized for an earlier sleep study. Parents will be asked to record short video clips of their child sleeping, and then rate whether they think their child has OSA. Later, children will undergo a sleep study to compare to the ratings.
The purpose of this study is to learn about the effect of sleep apnea and low oxygen on muscle strength and lung function in people with chronic spinal cord injury.
