Summary
Snoring is the cardinal symptom of obstructive sleep apnoea (OSA), a major health issue in childhood with significant impacts on cognition, behaviour and cardiovascular health. Approximately 35% of children snore but only about 10% of those have OSA. Defining OSA in a snoring child requires polysomnography, a technically challenging and expensive test. In this study we will examine a number of simple tests for their predictive power for OSA, developing a tool that will enable clinicians to diagn ....Snoring is the cardinal symptom of obstructive sleep apnoea (OSA), a major health issue in childhood with significant impacts on cognition, behaviour and cardiovascular health.

Understanding The Relationship Of Incretin Hormones, Gastric Emptying And Reactive Hypoglycaemia

Summary
Low blood glucose levels following a meal occur frequently in otherwise healthy people and those who have had surgery for weight loss. It affects quality of life adversely and current management is unsatisfactory. The proposed studies will use sophisticated techniques to evaluate the roles of the rate of stomach emptying and the so-called 'incretin' hormones which stimulate the release of insulin after a meal. The outcomes will have major implications for more rational management.
In Search Of Airways Collapse - A Multimodal Device For The Diagnosis Of Obstructive Sleep Apnoea

Funding Amount
$479,786.00
Summary
Using a combination of off-the-shelf and emerging technologies we will develop a multimodal diagnostic device that will identify and characterize the points of airway collapse that occur in patients with obstructive sleep apnoea. Using this multimodal approach will allow sleep clinicians to recommend the best form of therapeutic intervention for each individual patient rather than the current strong reliance on positive pressure facemasks.
The SNORE-ASA Study: A Study Of Neurocognitive Outcomes, Radiological And Retinal Effects Of Aspirin In Sleep Apnoea

Summary
Sleep apnoea is very common in the elderly, but it is uncertain whether it leads to a decline in mental abilities as it can in the middle-aged. Apart from fatigue, sleep apnoea also causes mental decline by affecting brain blood supply. This may be preventable with aspirin. We will track 3,000 healthy elderly for 4 years, after testing for sleep apnoea. Half will take aspirin. We predict that mental ability will decline faster with sleep apnoea, and that aspirin will partly reverse this.
What Role Do Cerebral Hypoxia And Sleep Disruption Play In The Neurocognitive Effects Of Paediatric Sleep Disordered Breathing?

Summary
Sleep disordered breathing (SDB) describes a spectrum of disorders caused by obstruction of the upper airway during sleep from simple primary snoring (PS) to obstructive sleep apnoea (OSA). Findings of our recently studies have provided strong evidence that all levels of SDB severity including PS are associated with neurocognitive and behavioural deficits. In this study we will investigate the mechanisms of which underpin these deficits.
Novel Approaches For Targeted Sleep Apnoea Treatment And Management

Summary
>1million Australian adults have obstructive sleep apnoea (OSA). OSA has several causes. Untreated OSA is associated with major health consequences. <50% of OSA patients tolerate the main therapy, continuous positive airway pressure. New treatments are urgently required. This proposal aims to use and develop novel approaches to identify the causes of OSA on a per patient basis, improve current therapies and management approaches and test if new targeted therapies can be used to treat OSA.
Using Biomechanics To Prevent Injury And Treat Soft Tissue Disorders

Summary
In this fellowship, I will use biomechanical testing and analysis methods together with novel imaging methods to design and implement interventions to prevent injuries to children, and to improve treatment of obstructive sleep apnoea and complex disorders of the cerebrospinal fluid system.
Atrial fibrillation (AF) is the most common sustained cardiac rhythm disorder. Obstructive sleep apnea (OSA), is four times more common among patients with AF than without. OSA has been associated with a greater recurrence rate of AF after initially successful treatment of AF and treatment of OSA reduces recurrence of AF. To identify the underlying mechanisms, we aim to determine effects of OSA on atrial electrical activation and to characterize sleep apnea in AF patients in a more precise way.
Early Detection Of Pulmonary Exacerbation In Cystic Fibrosis Using Nocturnal Measurements Of Cough And Sleep

Summary
Cystic Fibrosis (CF), the most common lethal inherited disorder effecting Australians, is a medical success story, with survival increasing from 5 years in 1970 to 40 years now. However, lower respiratory tract infections remain the major problem in CF. This project will develop and test a simple, non-invasive device to detect early chest infections, allowing early treatment, improving quality of life and preventing lung scarring. Less hospitalisations will benefit both patients and hospitals.
