Summary
Until something goes wrong, we take it for granted that we can empty our bowels on a regular basis, at a time and place of our choosing. Failure to achieve this is very distressing and substantially diminishes quality of life, if it occurs regularly. Disordered defecation, fecal incontinence and constipation are surprisingly common and their prevalence will continue to increase as our population ages and the incidence of diseases such as diabetes increases.

Failure to achieve this is very distressing and substantially diminishes quality of life, if it occurs regularly. Disordered defecation, fecal incontinence and constipation are surprisingly common and their prevalence will continue to increase as our population ages and the incidence of diseases such as diabetes increases. In many people suffering these problems, there is a detectable dysfunction of the sensory nerves in the anal region. These nerves supply information from the anal region to the spinal cord that can cause us to sense activity in our lower bowel and initiate defecation reflexes. These sensory pathways are important for clinical gastroenterology, but remarkably little is known about them. We are now able to investigate what it is the sensory nerves in the anal region sense, what they look like and where they go to in the spinal cord - in a single project. To do this we will use simple, but novel techniques that have been developed in this laboratory in an animal model. Once we know this, we will compare the function of sensory nerves in the anal region in diabetic animals with normal animals. This will give us insight into the role of sensory nerves in the development of fecal incontinence an unpleasant symptom for many people suffering advanced diabetes. My systematic approach will provide understanding of the basic cellular mechanisms and nerve pathways that underlie sensation in the anal region, helping both clinicians and patients understand the cause of defecatory disorders and potentially pointing the way to new therapies and strategies for diagnosis.Read moreRead less
Alternatives To Polysomnography For Children With Suspected Obstructive Sleep Apnoea.

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.
