This project aims to improve the acute treatment of children with burn injuries through developing more effective and novel treatments and understanding the conditions required for burn injuries to occur.
In this Fellowship I will capitalise on my role as Professor of Surgery and Public Health at Monash University, Director of the National Trauma Research Institute, and a surgeon at The Alfred Hospital, to lead a program of research that improves our understanding of what works in trauma care and trauma systems, uses scientific strategies to ensure research makes a difference to practice and policy, and supports further research that seeks to understand how research can best be used to improve in ....In this Fellowship I will capitalise on my role as Professor of Surgery and Public Health at Monash University, Director of the National Trauma Research Institute, and a surgeon at The Alfred Hospital, to lead a program of research that improves our understanding of what works in trauma care and trauma systems, uses scientific strategies to ensure research makes a difference to practice and policy, and supports further research that seeks to understand how research can best be used to improve injured peoples' lives.Read moreRead less
Identification Of A Plasma Factor Of Remote Ischemic Preconditioning And Its Effect On The Proteome After Heart Surgery

Summary
Heart surgery with the heart placed into arrest causes inflammation and tissue damage due to interrupted circulation. We know that prior brief interruption and restoration of blood supply called remote ischemic preconditioning (IPC) can protect heart and lungs against damage. Our previous studies indicate that IPC involves a circulating factor that protects the tissue by optimizing energy preservation. This knowledge can be applied to organ transplants, protection from stroke and heart attack.
Pre-hospital Antifibrinolytics For Traumatic Coagulopathy And Haemorrhage (The PATCH Study)

Summary
About 2500 Australians die annually from severe injuries. Bleeding is exacerbated by early-onset clotting defects, which are associated with high mortality. The antifibrinolytic agent tranexamic acid has been shown to reduce mortality due to bleeding when given in hospital in less developed trauma systems, but its usefulness as a pre-emptive strike at the scene of injury in developed systems is unknown. Building on our prehospital clinical trials expertise, we will conduct a trial to assess its ....About 2500 Australians die annually from severe injuries.

Summary
Children’s burns are physically and psychologically debilitating and are a huge burden for the children themselves, their families and the Australian health care system. My work will determine exactly what conditions are required to cause burns so that we can act to prevent them. I will also develop more effective first aid treatment and new treatments to improve burn wound healing.

Research evidence plays a crucial role in improving clinical care. However the main forms of evidence and the tools that facilitate evidence use - namely randomised controlled trials (RCT) and structured systematic reviews of existing research - have had limited application in surgery for a variety of reasons. This project aims to promote the use of research evidence in surgical decision making by developing tools tailored to the predominance of non-RCTs in surgery and surgeons' information need ....Research evidence plays a crucial role in improving clinical care.

Summary
NHMRC 209113 LAY DESCRIPTION Ischaemia reperfusion injury occurs in skeletal muscle when the blood-oxygen supply is cut off (ischaemia) and later restored (reperfusion). 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 ....NHMRC 209113 LAY DESCRIPTION Ischaemia reperfusion injury occurs in skeletal muscle when the blood-oxygen supply is cut off (ischaemia) and later restored (reperfusion). 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
