Summary
Unfractionated Heparin (UFH) is the most commonly used anticoagulant (blood thinning drug) in children. Despite this, the clinical evidence, in terms of reported treatment failures and bleeding complications, suggests the drug is used suboptimally in children compared to adults.This likely relfects the lack of specific studies of UFH in children. This study will, for the first time, define the pharmacokinetics-dynamics of UFH in children, allowing age-specific protocols to be developed.

Pharmacological modelling of this data will likely have implications for the use of other anticoagulants in children.Read moreRead less
Chronotherapy For Hypertension In Obstructive Sleep Apnea

Funding Amount
$253,229.00
Summary
Obstructive Sleep Apnea (OSA) is a common cause of hypertension, however treatment of OSA only results in a modest improvement in blood pressure (BP) and patients who are unable to tolerate treatment must rely on pharmacotherapy to control their BP. This study will definitively establish if altering the time of taking medication can improve BP control over 24 hours. The results will conribute to the development of more targeted treatment strategies for hypertension in people with OSA.
Mechanisms Of Activation Of Vascular Afferent Nociceptors To The Gut

Summary
We have recently identified the nerve fibres responsible for detecting pain from the gut. In this project we will study exactly how these nerve cells are activated by movements of the gut wall, by changes in blood vessel diameter and how this can be studied most efficiently We will use this information to develop simple preparations in which to study these sensory nerves in animal and adult tissue to test which drugs may affect their excitability and hence be useful in treating gut pain.
Opioid Dependent Persons In Pharmacotherapy: Blood Borne Viruses And Cancer Risk

Funding Amount
$88,495.00
Summary
Opioid dependent persons in pharmacotherapy in NSW are at increased risk of death from cancer. We will examine the occurrence of infection with hepatitis and HIV among this high-risk population using data linkage. We will define the relationship between infection, the duration, frequency and type of pharmacotherapy, and cancer risk. The findings will guide effective strategies that will reduce cancer incidence and mortality among this group, and minimise the associated health care costs.
A Novel Tumour-targeting Nanoliposome Drug Delivery System For The Treatment Of Malignant Gliomas

Funding Amount
$445,097.00
Summary
Most patients with malignant brain tumours die within a year after diagnosis due to the difficulty in effectively delivering drugs to the tumour cells. We aim to develop a safe and novel drug delivery system to effectively deliver anticancer drugs and novel anticancer agents to brain tumour cells that remain in normal brain after surgery. The success of this project will bring us a step forward in our efforts to significantly improve the survival rate and quality of life of such patients.
Sacral Parasympathetic Innervation Of Distal Bowel

Funding Amount
$314,983.00
Summary
Not a topic for polite conversation, normal movements of the colon and rectum are essential for good health and a sense of wellbeing. Constipation, diarrhoea, incontinence and pain result from disordered motility. One major control mechanism is the parasympathetic innervation. While we know of its importance, how it works in health and diseases is poorly understood. This project will use state-of-the-art techniques to study this pathway in order to understand its role in health and disease
Lifestyle And Pharmacological Regulation Of Lipoprotein Metabolism In The Metabolic Syndrome

Summary
Visceral obesity is an increasing problem in Australia. Elevated blood fat levels are associated with visceral obesity and increased risk for heart disease. Effective management of lipid disorders is important to reduce the risk for heart disease. Fats in the blood originate from dietary sources and from synthesis by the liver. In viscerally obese subjects, the level of blood fats is elevated compared with lean individuals.

Elevated blood fat levels are associated with visceral obesity and increased risk for heart disease. Effective management of lipid disorders is important to reduce the risk for heart disease. Fats in the blood originate from dietary sources and from synthesis by the liver. In viscerally obese subjects, the level of blood fats is elevated compared with lean individuals. These abnormalities are partly caused by overproduction of fat in the liver and impaired clearance of fat from the blood. Two particular proteins, called apolipoprotein A and B-100, are important fat carriers responsible for transporting fat in the blood. Viscerally obese subjects have abnormal levels of these apoproteins and we hypothesised that they are responsible for the impaired movement of fat in the blood. Viscerally obese subjects are insulin resistant and are prone to diabetes. This condition will impair the regulation of apolipoproteins A and B-100. In this research project, we will investigate the effect of a fibrate (a regulator of fat production and breakdown) and ezetimibe (a regulator of dietary cholesterol absorption) on the production and clearance rates of apolipoprotein A and B in a group of obese subjects who are on weight loss program . If our hypothesis is correct, these studies will demonstrate new mechanisms of action of the two drugs that will complements the favourable effect of weight loss in the treatment of elevated blood fats and reduction in risk of heart disease in an important groups of subject in the population.Read moreRead less
A Longitudinal Population Based Study Of Alzheimer's Disease: Prescription Drug Use And Survival
Funder
National Health and Medical Research Council
Funding Amount
$186,353.00
Summary
Population linked health data (2002-2009) will be used to study patterns of care and outcomes for people with Alzheimer's disease. Use of prescription drugs to treat Alzheimer's disease, the survival experience from time of first supply of Alzheimer medication and the identification of inequalities in accessing medications will be examined. The research will provide critical data for strategic sustainable healthcare planning and assist in the development of dementia-specific healthcare policies.
The Real And Changing Atherothrombotic Disease Burden And Secondary Prevention

Funding Amount

Summary
Absolute numbers of Australians with diseased narrowed blood vessels in the heart, brain or leg are increasing, dominating health priorities and expenditure. By linking Department of Health datasets, without identifying individual's, trends in hospital admissions, prescription of chronic protective medications and the cost consequences to the health system among and across conditions will be determined. The findings will provide quality measures of hospital care and inform quality improvement
