Summary
Acute rheumatic fever (ARF) is now rare in developed countries. However, it remains a major problem in Aboriginal Australians in the NT where the rate of ARF is the highest in the world. This leads to high rates of rheumatic heart disease (up to 3% of individuals in some communities) and a premature mortality of over four times that for developing countries. Immunisation and improved living conditions offer a long-term solution but these remain a distant prospect. In the short and medium term, c ....Acute rheumatic fever (ARF) is now rare in developed countries. However, it remains a major problem in Aboriginal Australians in the NT where the rate of ARF is the highest in the world. This leads to high rates of rheumatic heart disease (up to 3% of individuals in some communities) and a premature mortality of over four times that for developing countries. Immunisation and improved living conditions offer a long-term solution but these remain a distant prospect. In the short and medium term, control of this ARF will partly depend on new and better treatment and prevention strategies. To achieve these goals a deeper understanding of the immune mechanisms underlying this disease is urgently needed. It is known that ARF is caused by an abnormal immune response following streptococcal infection. This leads to the production of cells called T cells that attack the body s own tissues rather than the bacteria itself. This autoimmune disease is responsible for the heart damage that underlies ARF. It is believed that this proces only occurs when susceptible individuals are infected with specific rheumatogenic strains of streptococci. However there are a number of deficiencies in this model and it is proposed that there is an additional factor responsible for the abnormal immune response in ARF. This project will explore the possibility that bacterial toxins called superantigens are the critical missing factor , by studying the immune response in ARF. Superantigens are produced by certain streptococci and staphylococci, and are potent in minute quantities causing widespread activation of the immune system. They have been found to play an important role in a number of autoimmune diseases and the type of immune response found in ARF fits well with that expected if superantigens were involved. If superantigens play an important role in causing the abnormal immune response in ARF then a number of new avenues would open for the treatment and prevention of this disease.Read moreRead less
Yarning with our mob about human papillomavirus (HPV) vaccination uptake. This project aims to identify a range of modifiable factors that affect the participation of Indigenous adolescents in human papillomavirus (HPV) vaccination school programs. The project expects to generate new knowledge by combining Indigenous methodologies and a socioecological model to explore policy, community, interpersonal and intrapersonal factors impacting HPV vaccination uptake for this population.

This project aims to identify a range of modifiable factors that affect the participation of Indigenous adolescents in human papillomavirus (HPV) vaccination school programs. The project expects to generate new knowledge by combining Indigenous methodologies and a socioecological model to explore policy, community, interpersonal and intrapersonal factors impacting HPV vaccination uptake for this population. Expected outcomes include a more comprehensive understanding of the factors behind the low rates of HPV vaccination among Indigenous adolescents. This information should provide significant benefits including the identification of modifiable factors to increase HPV vaccination rates for Indigenous adolescents.Read moreRead less

This project aims to examine the genetic variants introduced by Europeans (and other groups) into the genomes of the Aboriginal Australian population.

The effect of genomic variants on Indigenous health. This project aims to examine the genetic variants introduced by Europeans (and other groups) into the genomes of the Aboriginal Australian population. The rate of metabolic diseases such as diabetes and hypertension is very high in Australia’s Indigenous populations. While an energy-rich Western diet has been suggested as the major cause, the contribution of genomic variants (mutations) remains unclear. Anticipated outcomes are better understandings of both the benign and deleterious variants introduced into Aboriginal Australian populations and how these contribute to disease susceptibility.Read moreRead less
Developing an evidence base to improve the health of Aboriginal and Torres Strait Islander people. This project addresses two critical health needs for Indigenous Australians, namely cancer and infectious diseases. It will test interventions in each area with the aim of improving health outcomes.
Developing a research focus on the health and quality of life of adolescents in the Northern Territory. The Youth Futures program will focus on the health and well being of adolescents in the Northern Territory, 40 per cent of whom are Indigenous. This project will provide an evidence base to inform health policy, identify transformative life skills and the ways to translate these into practice.
A Randomised Controlled Trial Of Alternative Treatments To Intramuscular Penicillin For Impetigo In Aboriginal Children

Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.

Aboriginal and Torres Strait Islander communities are currently experiencing severe environmental challenges related to a changing climate. Led by Aboriginal communities, this project aims to integrate traditional knowledges and environmental and health data to create community story-data maps. These interactive, online maps will be a unique and powerful blend of information, providing a rich evidence base, decision-support and communication tool to inform the co-design of local climate change mitigation, adaptation and resilience plans. The project aims to give agency to Aboriginal communities in leading a systems change process to reduce environmental risks and strengthen health and wellbeing.Read moreRead less
Testing for scale up: An Indigenous social and emotional learning program . This project takes key learnings from prior research that conceptualised, set up, and tested a social and emotional learning program, Skills for Life (SFL), with Aboriginal and Torres Strait Islander students in grades 7-9 in remote Northern Territory and Queensland schools.

This project takes key learnings from prior research that conceptualised, set up, and tested a social and emotional learning program, Skills for Life (SFL), with Aboriginal and Torres Strait Islander students in grades 7-9 in remote Northern Territory and Queensland schools. It aims to: establish the process and necessary conditions for scaling up SFL to diverse remote schools with Aboriginal and Torres Strait Islander students across Australia's top end. Further evidence for the program’s effectiveness will also be built by measuring students’ resilience, help seeking, and psychological distress; and teachers’ cultural awareness; quality of teacher-student relationships, and perceptions of students’ emotional and behavioural difficulties.

Summary
As part of his Senior NHMRC Fellowship, Prof Simon Stewart, a world-renowned health services researcher, will lead an internationally linked team of researchers from a broad range of health disciplines to undertake a program of research designed to improve the lives of those most vulnerable to heart disease and poor health outcomes. His program of research will focus on Indigenous Australians, patients with complex forms of heart disease and urban African communities in economic transition.

People accessing the National Disability Insurance Scheme (NDIS) are required to complete a personalised service plan, however despite these reforms, people in rural and remote communities currently experience many challenges with the scheme. Using qualitative research methods, the project will investigate people’s experiences engaging with Local Area Coordinators and Planners under the Rural and Remote Strategy 2016-2019 and Aboriginal and Torres Strait Islander Engagement Strategy. The project will provide significant outcomes for Aboriginal and non-Aboriginal people with disability in rural and remote areas, disability service providers, and government and non-government policy makers.Read moreRead less
