Summary
It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of ....It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of the cause of ARF, and have important implications for prevention of ARF around the world. Presently, these approaches focus on diagnosing and treating sore throat, but no country has proven that such a program can be successful in substantially reducing new cases of ARF. If it was known that skin infection could lead to ARF, then countries (including Australia) could emphasise the importance of skin health programs. A further benefit of this knowledge would be to influence GAS vaccine development, which presently is largely focused on the prevention of sore throat. A different possibility has recently been raised - that the cause of ARF may not always be GAS, but instead that the related bacteria GCS and GGS may have the potential to cause this disease. Proof of this hypothesis would even more dramatically alter our understanding of disease causation, prevention, and vaccine development. We propose to determine the cause of ARF in Aboriginal communities by regularly swabbing families of people with a history of ARF, and using genetic fingerprinting of the bacteria from the skin and throat swabs. When cases of ARF occur, we will be able to determine the site and type of infection that precipitated the attack. We will conduct a related study in more communities, in which we will swab family members of people with ARF and of control families (without ARF) to determine the bacteria most commonly isolated from ARF families.Read moreRead less

Summary
Urban consolidation and sprawl, traffic congestion, mining, climate change, heating and cooling living environments, and power generation – these manifestations of modernity produce regular headlines. Air pollution and its effects on human health are the focus of much popular concern. This CRE will build an integrated research capacity in the field of air pollution and its effects on human health that will allow Australia to address these major challenges - now and in the future.
Drivers of ageing and adaptive ageing in middle-aged and older adults. This project aims to answer crucial questions about how our early years influence our health and wellbeing in middle and later life. Drawing on one of Australia’s longest running studies of social and emotional development, we link decades of developmental data collected since 1983 to social, emotional, cognitive and physical wellbeing in participants turning 40 (midlife) and 70 (later life). It will provide insight into impo ....Drivers of ageing and adaptive ageing in middle-aged and older adults.

Drawing on one of Australia’s longest running studies of social and emotional development, we link decades of developmental data collected since 1983 to social, emotional, cognitive and physical wellbeing in participants turning 40 (midlife) and 70 (later life). It will provide insight into important and largely unanswered questions about the way social factors in the first half of life shape our later selves. This study will inform government and health policy targeting ageing populations.

Funding Amount
$2,491,229.00
Summary
Emissions from burning biomass (including fossil fuels) are major features of our environment and are the 4th leading global risk factor for premature death. As countries shift their patterns of energy use in response to global warming, new challenges are emerging. Understanding this is crucial to our ability to maintain health and stability in uncertain times. This CRE will examine the health consequences of (1) fossil fuel combustion, (2) landscape fires and (3) alternatives to fossil fuels.

Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if the Cryptosporidium in humans is the same as that derived from water contamination sources (animals, sewage etc). The outcomes of this project will result in the development of more targeted, cost-effective preventive measures to minimize exposures to infections, accurate risk assessment, and scientific management of the watershed.Read moreRead less

Families with multiple and complex needs have been determined to be a priority group in Australia (National Child Protection Framework 2021-31). This study will fill the evidence gap by determining the typologies of families with multiple and complex needs and child protection involvement who face intersecting risk factors (e.g. family violence, mental health, intergenerational trauma, alcohol/drug use, justice involvement, disability, poverty and housing insecurity). Intergenerational (child and parent) linked data in three states will be utilised to investigate these families longitudinal trajectories of system involvement and to identify opportunities for enhanced prevention, points of early intervention and service planning.
