Funding Amount
$275,203.00
Summary
Skin cells grown for clinical applications currently require animal-derived cells and-or non-defined products for their expansion in the laboratory; these reagents can potentially infect patients who receive these therapies. This project will identify the essential components provided by these reagents and develop a fully synthetic and defined culture system. This improvement will provide safer, cost-effective grafts and cell-based therapies that will benefit patients suffering burns and wounds.
A Randomised Controlled Trial Of A Promising New Treatment For Chronic Whiplash

Funding Amount
$620,556.00
Summary
Following a whiplash injury about one third of people develop persisting pain and disability i.e. chronic whiplash. In a series of pilot trials we have developed a new physiotherapy treatment for chronic whiplash. Initial results are very promising. We now propose to definitively establish the effectiveness of this new treatment in a large clinical trial. At the same time we will evaluate the cost-effectiveness of the treatment.
Combined Dry-needling, Advice And Graded Exercise: A Randomized Controlled Trial In Chronic Whiplash
Funder

Funding Amount
$309,339.00
Summary
Central hyperexcitability is a feature of chronic whiplash and may be one reason for the poor response of this condition to standard treatment approaches such as exercise. Complementary and Alternative Medicine (CAM) treatment of dry-needling has shown potential to decrease this hypersensitivity in other musculoskeletal conditions. This study will investigate the effects of dry-needling combined with an orthodox treatment of advice and graded exercise on pain and disability in chronic whiplash.

Summary
Cysts in the spinal cord (syringomyelia) develop in children and young adults with congenital spinal cord abnormalities such as spina bifida, and in people of all ages after spinal cord injury or meningitis. Syringomyelia causes pain and paralysis that usually does not improve even with treatment. The current lack of knowledge about the mechanism of spinal cord cyst formation and enlargement is preventing the development of effective therapy. We have previously shown that some types of spinal co ....Cysts in the spinal cord (syringomyelia) develop in children and young adults with congenital spinal cord abnormalities such as spina bifida, and in people of all ages after spinal cord injury or meningitis. Syringomyelia causes pain and paralysis that usually does not improve even with treatment. The current lack of knowledge about the mechanism of spinal cord cyst formation and enlargement is preventing the development of effective therapy. We have previously shown that some types of spinal cord cysts enlarge by the normal fluid surrounding the spinal cord being pumped around small arteries into the centre of the spinal cord. The mechanism of enlargement of post-traumatic spinal cord cysts remains unknown, and this debilitating type of syringomyelia remains difficult to treat. Our hypothesis is that post-traumatic spinal cord cysts also enlarge by fluid being pumped into them around small arteries. A further hypothesis is that reductions of arterial pulsations and of the pressure in the fluid surrounding the spinal cord will prevent or inhibit cyst enlargement. These hypotheses will be tested by examining fluid flow in models of post-traumatic syringomyelia in rats and sheep. We have established a model of post-traumatic syringomyelia in rats and the first phase of the project will be to refine and characterize this model and to reproduce it in sheep. The second phase will be to determine whether these cysts enlarge by a flow of fluid around small arteries that is driven by arterial pulsations, as they do in other types of syringomyelia. The final phase will be to determine whether reducing the pressure in the fluid around the spinal cord prevents cyst enlargement. Confirmation that these techniques prevent cyst enlargement would open up new possibilities for the treatment of human syringomyelia.Read moreRead less
Determining The Cellular Mechanism Underlying Diffuse Axonal Injury Following Brain Trauma

Funding Amount
$400,885.00
Summary
Traumatic head injury causes transient stretch injury to the nerve cell processes within the brain. This leads to a poorly understood series of cellular changes within nerve cells which may ultimately lead to their breakage and subsequent neurological disability. This project seeks to understand how this nerve cell damage forms, and explores new potential interventions which may protect the brain.
Buckle Up Safely: Pre-school Based Interventions For Appropriate Use Of Child Restraints.

Funding Amount
$731,552.00
Summary
Despite overwhelming evidence that child restraints dramatically reduce the risk of death and injury there are currently a large number of children globally who either do not use appropriate child restraints, or misuse them, contributing to the overwhelming burden of road traffic injury in children. This project, using rigorous methodology, will assess the efficacy of feasible, evidence based interventions aimed at increased use of appropriate restraints, and decreasing misuse.
THE ROLE OF RESIDENT MAST CELLS IN ISCHAEMIA-REPERFUSION INJURY OF SKELETAL MUSCLE.

If the duration of ischaemia is short some of the muscle survives.

If the duration of ischaemia is short some of the muscle survives. However, when blood flow and oxygen are restored the muscle is subjected to more injury, which is thought to be caused by oxygen and-or white blood cells. This type of injury occurs in muscle which has been crushed, limbs that have been broken or traumatized, in replantation of amputated parts, in transplantation, after some surgical procedures and after microsurgical transfer of muscle. Once established there is no effective treatment. Our experiments show that a particular cell, the mast cell, and a particular molecule, nitric oxide, are involved in causing ischaemia reperfusion injury. However, the extent of their involvement is unknown. In this proposal we will investigate the effect of replacing mast cells into muscles, in a unique variety of mice which normally don t contain mast cells and are resistant to ischaemia reperfusion injury. In one group of mice we will put back normal mast cells and in a second group of mice we will put back mast cells that cannot produce the nitric oxide molecule. These experiments will determine, unambiguously, the extent of involvement of mast cells and mast cell-derived nitric oxide. In the second part of this proposal will carry out a time course study, using pharmacologically induced mast cell degranulation, to determine when the mast cells become injurious to skeletal muscle. These experiments will identify the period during which mast cell behaviour can be modulated in order to protect the muscle from ischaemia reperfusion injury. Determination of the role of mast cells, and an understanding of the timing during which they become injurious would provide a logical basis for optimizing drug therapy in clinical applications of these findings.Read moreRead less
Development Of A Novel Bioengineered Tissue Construct For Repairing The Eye.

Summary
Corneal diseases are often treated using donor tissue transplants. Nevertheless, donor tissue is unsuitable for treating the peripheral or limbal margin of the cornea. We have therefore developed a way to transplant sheets of limbal tissue (epithelium) grown in the laboratory from a patient's own cells, but this tissue lacks a foundation of connective tissue that we believe is essential for sustained healing. Thus, our aim is to develop a novel limbal transplant which contains both layers.

Summary
Traumatic brain injury is very common, with more than 2,000 people surviving serious brain injury in NSW each year. The survivors are most commonly young adult males and many are left with permanent brain damage, invariably affecting cognitive abilities. The impact of cognitive impairments on the person's capacity to resume their premorbid lifestyle is enormous. In one of our studies we found that 40% did not work but nor did they have any meaningful occupational activity to replace work.

The survivors are most commonly young adult males and many are left with permanent brain damage, invariably affecting cognitive abilities. The impact of cognitive impairments on the person's capacity to resume their premorbid lifestyle is enormous. In one of our studies we found that 40% did not work but nor did they have any meaningful occupational activity to replace work. The current project targets this large group of people in particular. The study aims to develop and test two alternative, intensive cognitive treatment programs that are geared to increasing community participation, everyday activities and psychological well-being. To date, no such therapies have been evaluated using powerful methodological designs. As a result of the study we will be able to incorporate the standardised interventions into a format that can be easily applied to Brain Injury Rehabilitation Services in Australia. The programs will not only improve the functioning of the individuals with brain injury, but will have a flow-on effect for their families and the community at large.Read moreRead less
