Summary
The operation to remove blockages in the carotid arteries (carotid endarterectomy) is of proven benefit in the prevention of stroke. The procedure itself, however, unfortunately carries approximately a 1 in 20 risk of immediate and early postoperative stroke. Most strokes are caused by blood clots forming at the operation site, breaking off and travelling to the brain (embolism). The up front operative risk is usually accepted by most patients in order to achieve the significantly greater long t ....The operation to remove blockages in the carotid arteries (carotid endarterectomy) is of proven benefit in the prevention of stroke. The procedure itself, however, unfortunately carries approximately a 1 in 20 risk of immediate and early postoperative stroke. Most strokes are caused by blood clots forming at the operation site, breaking off and travelling to the brain (embolism). The up front operative risk is usually accepted by most patients in order to achieve the significantly greater long term benefits of future stroke risk reduction. This study is designed to test a medication (dextran) thought to possibly prevent stroke associated with the operation. Dextran acts in part, by preventing blood clots forming at the operation site . In a pilot study undertaken by the researchers, dextran significantly reduced the downstream shedding of small blood clots (microemboli) detected by monitoring brain arteries using specialised ultrasound techniques. It remains to be proven, however, whether this effect on microemboli actually translates into the prevention of stroke complicating surgery. The DICE (Dextran In Carotid Endarterectomy) Trial aims to assess whether dextran can reduce the risk of stroke associated with carotid surgery by 50% or more. It has important implications for the increasing numbers of Australians being offered this operation (5,000-6,000 each year). If the therapy is proven effective there will be the potential to prevent 350-450 strokes and stroke related deaths each year.Read moreRead less
Stroke outcomes directly relate to brain tissue rescue. We have contributed to changes in clinical practice through many clinical trials of new protocols and therapeutic strategies. Our program will focus on brain salvage in the pre-hospital setting and the acute hospital environment. We will use novel approaches to enhance brain recovery and design new implementation strategies to maximise the benefits of these therapeutic advances.
I am a practising hospital neurologist and world leader in the prevention and treatment of stroke. Our research aims to realise exciting new break-throughs for stroke sufferers by testing the effectiveness and safety of new treatments that promise to improve recovery of function of damaged brain and reduce disability after stroke, and to prevent recurrent strokes.

Summary
Various medications have been shown to reduce the risk of recurrent vascular disease after stroke. This study aims to improve the frequency of use of these medications in patients discharged from hospital after a stroke.
My work focuses on the prevention of vascular disease. A major aim of mine is to improve outcome after stroke. We can test this by assessing whether individualised management plans provided to people with stroke will improve risk factors. Proper risk factor management reduces the risk of stroke recurrence. I also aim to reduce the burden of vascular disease in disadvantaged settings by finding out what risk factors are important in the development of these diseases in people living in poverty.
Healthy Living After Stroke: An Online Intervention For Improving Stroke Survivor Health Behaviours And Quality Of Life

Summary
This study will test whether an online healthy lifestyles program helps survivors of stroke to live healthier lives, improve their quality of life and prevent a second stroke.
Stroke is Australia's second single greatest killer and a leading cause of disability, with high blood pressure associated with a greater risk of stroke occurring. We have evidence of a possible new target, the angiotensin type 2 receptor that is protective in stroke. This proposal involves elucidating the mechanisms underlying this protective effect which may lead to new therapeutic strategies in treating stroke.
