Funding Amount
$150,000.00
Summary
In this project new DNA-based technology will be developed to determine the numbers of specific bacteria in the dental plaque of patients. The project will also use new mass spectrometric analysis techniques for the determination of compounds in gingival crevicular fluid, an exudate from the gums. These two techniques will be used in a clinical trial to determine if periodontal (gum) disease progression can be predicted by changes in the numbers of bacteria or in the composition of gingival crev ....In this project new DNA-based technology will be developed to determine the numbers of specific bacteria in the dental plaque of patients.

These two techniques will be used in a clinical trial to determine if periodontal (gum) disease progression can be predicted by changes in the numbers of bacteria or in the composition of gingival crevicular fluid. This could provide insight into the development of periodontal disease and lead to new preventive and treatment regimes.Read moreRead less
Developing Interpretable Machine Learning Models For Clinical Imaging And Single-cell Genomics

$1,312,250.00
Summary
Machine learning methods will be vital to make best use of the deluge of data generated by high-throughput technologies in biomedical science. To get the most out of these models, however, we need to be able to unpack the 'black box'. I will use curated clinical and public research data to benchmark and develop interpretable deep learning models and software tools. These models will be used for breast cancer screening programs and for analysis of complex, large-scale single-cell genomics data.
Enabling Personalised Risk Assessment For Colorectal Cancer

Summary
Bowel cancer screening will be most effective in disease prevention if it is applied proportionately to individual person's risk. Risk-based screening requires a risk calculator to assess personal risk. By utilising existing large, international datasets, I will identify the risk factors specific for different bowel cancer types and incorporate them to upgrade the prediction model that I have developed. This will achieve more accurate risk prediction to enable personalised risk-based screening.
Validation Of A Multiplexed Blood Based Screening Assay For The Diagnosis Of Colorectal Cancer

Funding Amount

Summary
Colorectal cancer (CRC) is the second most common cancer in Australia with poor patient outcome due to late detection of the disease. We have developed a simple blood based test that can diagnose individuals with CRC at an early stage when the chance of cure is greater than 80%.
Advanced Non-invasive Cardiovascular Risk Screening In The Community: Practical And Cost Effective?
Funder

Funding Amount
$287,321.00
Summary
This research focuses on the practicalities and cost of mobile, advanced, non-invasive cardiovascular assessments to determine the extent of CVD and clinical risk factors and its likely impact on patterns of treatment and care to “disadvantaged” individuals living in rural and remote regions and Indigenous Australians. The advantage of directly acquiring risk profile information has not been fully explored and its potential to address an “epidemic” of CVD world-wide cannot be overstated.
Evaluation Of The Efficacy Of The Australian Mammographic Screening Program

Funding Amount
$504,096.00
Summary
BreastScreen Australia uses interim measures such as participation, small cancer detection and interval cancer rates to monitor the impact of the program on mortality. Using BreastScreen Victoria as a case study, we will estimate the direct impact of the program on mortality for screened women, addressing Cancer Australia's priority of 'Improving screening program outcomes to ensure that patients can be identified and treated appropriately and ensuring that screening services are effective'.
What Can Tau Deposition Tell Us About The Appearance Of Subjective And Objective Cognitive Decline In Older Adults?

Summary
Subjective memory concerns are common in older adults, but it is uncertain how they relate to Alzheimer’s disease (AD) biomarkers. Novel neuroimaging techniques have been developed for measuring tau deposition, a hallmark feature of AD. Using this technique, I aim to determine whether tau is sensitive to certain types of subjective concerns. My findings will reveal which concerns are indicative of AD risk, and which arise from unrelated factors, such as inattention or stress.
Early Detection Of Infants And Young Children With Autism

Summary
Autism is a severely handicapping condition adversely affecting social interaction, communication, behaviour, interests, and activities. Autism requires treatment at an early age (before 4 years). Despite finding that parents notice problems with their child's development within the first 2 years, on average diagnoses are made around 6 years of age. Treatment for autism should begin as early as possible to improve outcome. Diagnosis requires specialist assessment and these services are limited. ....Autism is a severely handicapping condition adversely affecting social interaction, communication, behaviour, interests, and activities. Autism requires treatment at an early age (before 4 years). Despite finding that parents notice problems with their child's development within the first 2 years, on average diagnoses are made around 6 years of age. Treatment for autism should begin as early as possible to improve outcome. Diagnosis requires specialist assessment and these services are limited. Therefore it is not possible to undertake such assessments with all children who have developmental problems. This project therefore proposes to evaluate a method for screening large populations of children for autism, thus enabling timely and more appropriate referral to assessment services. Previous work by the investigators has developed a potential screening tool (DBC Early Screen) for autism in young children under 4 years with developmental delay that has high levels of accuracy in identifying those infants and children who are at risk of autism and require specialist assessment. This project proposes to undertake a community field trial to assess the accuracy and reliability of this early screen and to establish its suitability for wide use as a population screening tool. The preliminary testing of DBC Early Screen demonstrated that a community field trial was feasible. The results of this study will facilitate the referral of infants and young children to specialist autism assessment services, thus enabling the commencement of appropriate early intervention for children and their families from an early age.Read moreRead less
Mechanisms Underlying APOBEC3G Restriction Of HIV-1

Summary
In the fight against worldwide HIV-AIDS, understanding natural cell defenses to the HIV virus may identify new virus targets and strategies to block HIV in humans. Here, we will use state-of-the-art, high resolution, fluorescent microscopy to understand how the recently identified cell protein, APOBEC3G, blocks the HIV life cycle in human cells. We anticipate that APOBEC3G will stop HIV from invading the nucleus of human cells to defend against HIV, a strategy we can apply to new therapies.
Improving Mental Health Screening For Aboriginal And Torres Strait Islander Pregnant Women And Mothers Of Young Children

Funding Amount

Summary
Mental health during and after pregnancy is important for the well-being of mother and infant. Unfortunately Aboriginal women in remote Australia have high levels of anxiety and depression, which can have significant short and long-term impacts on both mother and child. Currently these issues are often not identified and if identified services may not feel equipped to address them. This study aims to improve screening for, and contribute to addressing, perinatal mental health issues.
