Predicting Dysphagia-related Complications And Improving Outcomes In Patients Treated With Head And Neck Radiotherapy

Funding Amount
$311,597.00
Summary
This project aims to improve swallow-related quality of life in patients undergoing head and neck radiotherapy by: 1) Identifying throat muscles, critical to swallowing in order to refine future radiation strategies in order to minimise collateral damage to these critical structures; 2) Improve health care management of post-radiotherapy patients via identification of markers that predict response to therapy; 3) Evaluate a therapy to improve swallow dysfunction
Mechanical Factors In Normal Human Colonic Motility

National Health and Medical Research Council
Funding Amount
$650,023.00
Summary
Abnormal human colonic contractions cause significant medical, societal and financial burdens. Diagnosis and treatment of motility disorders requires an understanding of normal colonic contractility against which to measure dysfunction. Through state-of-the-art recording and analytical techniques, developed by the applicants, this project will provide the first clear description of normal human colonic motor patterns and how they are generated.
An Objective Screening Test For Deglutitive Aspiration And Swallowing Function In Children With Dysphagia

Funding Amount
$476,641.00
Summary
Swallowing dysfunction (dysphagia) is common in children with neurological diseases such as cerebral palsy which affects 1:400 births. Fluid in the lungs during swallow (aspiration) is a serious complication causing chest infections and potentially death. We have developed a new test measuring pressures and flows during swallow which can detect abnormalities predisposing to aspiration and we will evaluate this as a screening tool.
In Search Of Airways Collapse - A Multimodal Device For The Diagnosis Of Obstructive Sleep Apnoea
Funder
National Health and Medical Research Council
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.
Gastric Motility And Blood Glucose Control In Diabetes Mellitus

Summary
The recent application of novel techniques to evaluate gastrointestinal motor function has established that the rate of which the stomach empties food is slow in up to 50% of people who have insulin-dependent (type 1) or non-insulin dependent (type 2) diabetes. Delayed stomach emptying was thought to be an infrequent complication in diabetes; much less common than damage to the eyes, kidneys or nerves. It is now recognised that disordered stomach emptying may contribute to a number of problems i ....The recent application of novel techniques to evaluate gastrointestinal motor function has established that the rate of which the stomach empties food is slow in up to 50% of people who have insulin-dependent (type 1) or non-insulin dependent (type 2) diabetes. Delayed stomach emptying was thought to be an infrequent complication in diabetes; much less common than damage to the eyes, kidneys or nerves. It is now recognised that disordered stomach emptying may contribute to a number of problems in diabetes, e.g. symptoms such as nausea and bloating and poor control of blood glucose concentrations. In some people symptoms are disabling and affect quality of life adversely. The effects of stomach emptying on blood glucose control is likely to be important, as it is desirable to maintain blood glucose levels within the normal range to minimise the risk of both the development and progression of complications of diabetes. In many people with diabetes, particularly older people with type 2 diabetes, there is a fall in blood pressure after a meal which may result in fainting and falls. The magnitude of the fall in blood pressure is determined by the rate at which the stomach empties; faster emptying results in a greater fall in blood pressure. In the past both slow stomach emptying and symptoms were assumed to result from irreversible nerve damage, however it is now recognised that the blood glucose level itself has a reversible effect on both stomach contractions and symptoms. Our group has been the recipient of ongoing support from the NH and MRC for approximately 15 years to conduct research in this area. As a result we have performed the most comprehensive studies to date and developed new methods to evaluate stomach function in people with diabetes, resulting in international recognition. The studies proposed in this current application represent a logical development from our previous work and have important implications for the management of diabetes.Read moreRead less
Development Of Diagnostic Tools To Characterise Predictors Of Therapeutic Outcome In Severe Constipation
Funder
National Health and Medical Research Council
Funding Amount
$433,999.00
Summary
This project will use fibre-optic technology to create detailed high resolution maps of colonic motor patterns in both health and in patients with severe constipation. The data will be used in combination with actual patient symptoms to help identify specific markers of disease that can differentiate sub-types of constipation and ultimately guide and improve treatment in constipated patients
