Summary
A unique test that monitors the rate of switching between the hemispheres of the brain in response to visual stimuli has been devised. A patent application covers an apparatus and test to measure the switching rate between the hemispheres and the way in which such measurements can be used as a means to diagnose bipolar disorder (BD). BD, also called manic depression, is a form of depression that currently affects over six million people worldwide with about three million in the USA alone.

A patent application covers an apparatus and test to measure the switching rate between the hemispheres and the way in which such measurements can be used as a means to diagnose bipolar disorder (BD). BD, also called manic depression, is a form of depression that currently affects over six million people worldwide with about three million in the USA alone. The condition has phases of mania and depression and periods of remittance. Full cycles of BD can occur as many as three times a year and for many patients, this is a lifelong condition. BD is effectively treated, once it is diagnosed. It is estimated that 20% of sufferers go undiagnosed and many more are misdiagnosed. The cost of mis- or non-diagnosis is measured by suicides, the financial burden on society with health care, loss of productivity etc, effects on family and associates, crime, etc. Diagnosis to date is achieved mainly by subjective means such as questionnaires. These instruments do not conclusively separate BD from other forms of depression and schizophrenia, for which treatment is quite different. Nor do they allow for factors such as substance abuse and other medical conditions that the patient may be suffering. BD is hereditary with the slow hemispheric switch rate being an indicator of the genetic trait. This phenomenon allows for an objective test for BD, even if an individual has not had an episode of BD. The slow switch allows relatively easy separation of a BD patient from those exhibiting symptoms that may have other causes.Read moreRead less

Summary
This project will fund the construction of a clinically deployable prototype device to measure changes in upper airway size and shape in patients with obstructive sleep apnoea. We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published. To our knowledge, this is the only such system world-wide capable of making these important measurements.

We have recently developed and validated a technique based on endoscopic optical coherence tomography (OCT). Preliminary in vivo studies have been performed in the human upper airway and the results published. To our knowledge, this is the only such system world-wide capable of making these important measurements. The technique has wide commercially applicability as it can be used to measure the internal dimensions of any hollow organ system.Read moreRead less

Summary
Due to the growing incidence of obesity within Australia, use of computer technology may be a method of targeting these people by increasing access to dietary services. Currently available dietary software in the Australian context only allows analysis of nutrient information. Thus when a dietitian sees a patient they must manually translate food intake to nutrient information, a largely time consuming exercise.

Currently available dietary software in the Australian context only allows analysis of nutrient information. Thus when a dietitian sees a patient they must manually translate food intake to nutrient information, a largely time consuming exercise. DietAdvice is a website that was developed for people to enter in their own food intakes. The food information is sent to a dietitian who develops individualised dietary advice for them. A pilot study of the website has already found it to be feasible in the primary healthcare setting. Tested for 12 months the website was used by 224 patients from GP practices in the Illawarra region of NSW. Approximately 73% of patients were overweight and patients with a high BMI were 1.88 times more likely to use the website in the comfort of their home. Further research about the website however was needed. The research to follow on from the pilot study will aim to refine the DietAdvice website, leading towards its commercialisation for dietitians in clinical practice. The research will be broken into 3 phases. Phase 1 will involve a usability test of the website, assessing the underlying algorithms and testing it with dietitians in private practice. Phase 2 will see volunteers using the website on multiple occasions after being given pre-weighed amounts of food to eat. This will determine how reliable and accurate the information is; and phase 3 will evaluate whether the website is cost effective and if it increases accessibility of health services especially in rural areas. By confirming these attributes there will be a sound basis to commercialise the product.Read moreRead less
