The disease causes substantial human morbidity and mortality worldwide, and is endemic in Australia. Currently available drugs are poorly effective against the parasite and treatment of the disease relies mainly on surgical removal of often large parasitic cysts, where this is possible. Blood tests to identify people who are infected rely on the use of parasite samples obtained from animals, which leads to difficulties with adequate supply of material and quality control. Research in this laboratory discovered that the hydatid parasite produces a protein that binds the drug cyclosporin A and that specific antibodies are made to this protein in hydatid patients. Preliminary research by others found that cyclosporin A had anti-parasitic effects on hydatid disease in an animal model system. This research project will examine in detail the characteristics of the cyclophilin protein and related proteins, in the hydatid parasite, their interaction with cyclosporin A, the effects of cyclosporin A on the parasite in defined culture conditions, the mechanism by which cyclosporin A exerts anti-parasitic effects and the prospects for use of cyclophilin in tests for the diagnosis of human hydatid disease. The research will contribute to a better understanding of the basic biology of this pathogen and may identify improved methods for the chemotherapy and diagnosis of infection.Read moreRead less
Early Diagnosis And Prognosis Of Severe Dengue In Vietnamese Children

Funding Amount
$689,323.00
Summary
Dengue is a mosquito-borne viral infection. Tropical Australia has experienced multiple outbreaks of dengue in the last decade. This project, conducted in Ho Chi Minh City, Viet Nam, will define the accuracy of a rapid diagnostic test for the early diagnosis of severe dengue. In doing so, we will also derive an algorithm using simple laboratory and clinical findings that can help identify those patients at greatest risk of severe complications, with benefits for both patients and hospitals.

Summary
The retina of the eye displays features of Alzheimer's disease (AD). We have developed a new way to take photos of the eye with a rainbow-coloured flash to detect signs of AD. We now want to test how this and other eye imaging methods compare with brain scans and spinal fluid tests to identify people who are at risk of AD. We will use clinical studies, artificial intelligence, mouse models of AD and donated human tissues to achieve our aims. Our goal is to improve AD detection and care.
Preventing Complications Of Chronic Obstructive Pulmonary Disease

Summary
Chronic obstructive pulmonary disease (COPD) is a devastating lung disease that affects smokers. Lung complications and complications in other organs occur commonly. This study will examine factors that lead to exacerbations of COPD, and test the effectiveness of early diagnosis of coronary artery disease using CT scans.

Summary
My Fellowship will expand my work identifying diseases genes for genetic muscle and nerve diseases by using new technologies that allow discovery of human disease genes which could not be found before. In addition, since we now have proof from mouse studies that heart actin is a target for therapy for the group of diseases that we discovered caused by mutations in the muscle actin protein, we shall take further steps towards making this therapy a reality for patients.
Better Care Of Heart And Lung Disease For Aboriginal And Torres Strait Islander People In Rural And Remote Australia

Funding Amount
$380,583.00
Summary
Lung and heart disease are major contributors to the Aboriginal Australian and Torres Strait Islander health gap. This is even more so in remote and regional Australia. This Fellowship will generate new knowledge regarding how best to prevent, diagnose and treat heart and lung disease in this setting. Based in Alice Springs, it will bring together researchers and health care providers across northern and Central Australia and link them with our leading national research institutes.

Summary
End-stage renal failure is one of the commonest serious chronic diseases; in Australia, over 10,000 patients are in dialysis programs or have functioning transplants. The commonest cause of death in this patient group is coronary artery disease, and attempts are routinely made to identify patients with this problem, with the intent of controlling this risk by angioplasty or bypass surgery.

The commonest cause of death in this patient group is coronary artery disease, and attempts are routinely made to identify patients with this problem, with the intent of controlling this risk by angioplasty or bypass surgery. Unfortunately, these procedures may be less effective than usual, because the process of artery narrowing is more aggressive in patients with renal disease. Moreover, this process may cause patients with negative testing for coronary disease at one point in time to develop coronary problems over follow-up. In this study, we propose to use a standard stress testing protocol to stratify the risk of coronary events in a group of at risk patients on dialysis. Those at highest risk will undergo bypass surgery, while those at intermediate and low risk will be randomized to usual care, or an aggressive treatment of atheroma with cholesterol reduction, folic acid supplementation (aiming to normalize homocysteine), blood pressure and blood sugar control. The effects of this approach will be followed by examination of biochemical markers of atherosclerosis, and imaging of arterial thickness and reactivity (reflecting tests of structure and function of the vasculature). We will also assess of the progression or reduction of abnormal cardiac stress responses, and the occurence of events at follow-up. Finally, follow-up data will be used to compare the predictive value of the 2 stress testing protocols. The results of this study will enhance our understanding of the importance of the atherosclerotic process in renal patients, and move the management approach for coronary disease in renal failure toward active risk factor control and away from revascularization.Read moreRead less
Improving Diagnosis And Prognosis Of Early-onset Dementia

Summary
Frontotemporal dementia accounts for ~15% of all dementias. It is as common as Alzheimer’s disease in the < 65 year olds but understanding of this disease remains limited. Over the next 5 years, my research will work towards improving diagnosis, prognosis and prediction of pathology, using a multidisclinary approach that combines clinical, brain imaging, genetics and neuropathological investigations. This research will contribute to improving the care and quality of life of dementia patients.
