Summary
It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral ....It has been known for some time that the white matter regions of the developing brain are particularly vulnerable to damage. These regions are deep in the brain near the ventricles, and are rich in myelin sheaths wrapped around the nerve fibres running from cell-rich areas in the outer layers of the brain to other regions, and down into the spinal cord. Damage to white matter usually leads to behavioural, learning and motor problems in the newborn infant - in its severest form, seen as cerebral palsy. Such outcomes are often associated with the presence of asphyxia and infection during pregnancy, leading to the belief that the damage first arises while the baby is still in utero. In this application we suggest that asphyxia and-or infection during pregnancy cause prolonged disturbances in the regulation of blood flow and integrity of the blood-brain barrier in the developing brain, together with changes in metabolism that result in accumulation of prostaglandins and the toxic hydroxyl radical, leading irreversibly to cell death. If this series of events proves to be true, we have suggested and will test several protocols for protecting the fetal brain, which should be readily translatable to clinical practice.Read moreRead less
Intravascular Leukocyte Trafficking During Thromboinflammation

Summary
Unblocking blood vessels to treat heart attack and stroke can unfortunately cause a paradoxical worsening of organ damage, due to increased inflammation upon blood flow restoration. We have identified a novel way in which this side-effect is regulated by the small blood clotting cells platelets, and the protein fibrin. We will investigate ways to reduce the pro-inflammatory role for platelets, and define safer clot busting treatments.
STudy Of Risk Assessment To Reduce Complications In Patients Following Noncardiac SurgerY (STRATIFY)

Summary
Cardiac problems account for many complications in patients undergoing major non-cardiac surgery, and even apparently minor cardiac damage is a marker of high risk for subsequent adverse events. Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear. The performance of bypass surgery or balloon angioplasty in order to treat the underlying coronary disease of at-risk patients is used in other situations, and reduce ....Cardiac problems account for many complications in patients undergoing major non-cardiac surgery, and even apparently minor cardiac damage is a marker of high risk for subsequent adverse events. Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear. The performance of bypass surgery or balloon angioplasty in order to treat the underlying coronary disease of at-risk patients is used in other situations, and reduces longterm risk. However, in many patients undergoing major noncardiac surgery, this approach may be inappropriately aggressive, as these patients are often elderly, have other diseases that make heart operations more difficult and risky than usual, and in any case may have a reduced life expectancy from the disease necessitating the operation. As the most critical issue is to ensure that patients undergo their surgery uneventfully, an alternative is the use of intensive medical therapy to protect the heart. This multicentre study, based at Brisbane hospitals that perform large numbers of major operations, will follow up patients for complications, and outcome (including quality of life) will be assessed six months after the operation. We will address two important questions about the efficacy and cost of risk reduction strategies. First, in patients at higher levels of risk and with a positive stress test, could a combination of medical therapy designed to protect the heart be as effective as current approaches, which include the performance of bypass surgery or coronary balloon angioplasty? Second, in patients identified as being at some risk - but low risk - are drugs sufficiently effective to avoid the need for further testing to quantify risk? As the population continues to age, the numbers of at risk patients undergoing major surgery will increase, and answers to these questions will provide important information to guide their management.Read moreRead less
Towards A National Sports Safety Strategy - Addressing Facilitators And Barriers Towards Safety Guideline Uptake.

Funding Amount
$965,834.00
Summary
Most sports injury prevention evidence is yet to be translated from professional to community sports settings. Using community-based Australian football clubs, this project will develop and evaluate the strategic implementation of an evidence-based sports safety package. This will provide important information about how to best support community sports clubs to ensure evidence-based safety programs are translated into sustainable policies and practice and public health benefits are maximised
The Transition From Hospital To Home: A Longitudinal Study Of Indigenous Traumatic Brain Injury (TBI)

Summary
The six-month transition period following discharge from hospital after a traumatic brain injury (TBI) is critical. During the transition period, key sentinel events may influence health and wellbeing. The research will investigate key sentinel events during the transition period following TBI in the first longitudinal study with Indigenous Australians. This study will provide the first systematic evidence regarding the support Indigenous Australians need to successfully transition back into the
New And Improved Treatment Strategies For Neonatal Seizures

Funding Amount
$883,209.00
Summary
Around 10% of neonates in Australia are diagnosed with seizures each year. Seizures worsen neurodevelopmental outcome following hypoxic brain injury. Despite evidence of the limited effectiveness and potential neurotoxicity of current anti-seizure medication, treatment has not changed for many decades. The objective of this study is to optimise treatment of neonatal seizures with a compound that is effective and does not cause harm, or indeed provides neuroprotection for the compromised brain.
Understanding Burn Injuries In Aboriginal And Torres Strait Islander Children: Treatment, Access To Services And Outcomes.

Funding Amount
$911,798.00
Summary
This is the first large scale study to systematically examine the burden of burn injury in Aboriginal and Torres Strait Islander children, including care and cost of treatment, and relationship between access to treatment and functional outcomes. With a team comprising epidemiologists, burns clinicans and Aboriginal health researchers, this study will generate important new research evidence to improve care in this over-represented and vulnerable population.
