Implementing Multiple Imputation With Sensitivity Analysis In Large-scale Longitudinal Studies

Funding Amount
$473,507.00
Summary
Missing data arise in most research studies and if not handled appropriately can mean the study results are not correct. With researchers now conducting larger and longer studies the challenges posed by missing data are increasing. In this grant we study a powerful technique for handling missing data, which in its current form often cannot be applied effectively in large studies. By developing this approach we will improve the accuracy of results from large-scale epidemiological studies.
The Australia And New Zealand Fontan Registry: A Growing Population Of Young Adults With Heart Failure
Funder

Funding Amount
$129,103.00
Summary
The Fontan procedure is an operation performed for all children with heart defects who cannot be repaired with 2 pumping chambers like a normal heart. It is expected that after 2 or 3 decades, these patients will either die or need a heart transplantation. We want to establish a registry to evaluate the number and status of this increasing patient population. This study may foresee and even prevent a sudden burden on the health system caused by their needs.
The Australian Peritoneal Dialysis Outcomes And Practice Patterns Study (PDOPPS)

National Health and Medical Research Council
Funding Amount
$489,749.00
Summary
Peritoneal dialysis (PD) is a form of home dialysis that is both substantially cheaper and associated with better early survival than standard hospital-based haemodialysis. Its use in Australia has been severely limited by poor outcomes compared to the rest of the world. This international study aims to identify “real world” PD centre practices that will lead to better outcomes for Australian patients, greater uptake of home dialysis and health savings of tens of millions of dollars annually.
A Prospective Study Of The Influence Of Health-related Lifestyle Factors On DNA Methylation

Funding Amount
$640,074.00
Summary
It is known that DNA methylation can lead to disease. We aim to discover what causes DNA methylation to change. This could open the way for new methods of prevention and treatment of many diseases. We will study 1200 people to assess how the methylation of their DNA is influenced by changes in their smoking habits, alcohol consumption, vitamin intake, body size, blood sugar and cholesterol levels. We want to know whether these changes lead to undesirable (or desirable) changes in DNA methylation
The Evolution Of Childhood Obesity And Its Relationship To Adult Sleep Disordered Breathing

Funding Amount
$870,842.00
Summary
This project will characterise Obstructive Sleep Apnoea (OSA) in early adulthood. It will assess the prevalence of OSA in a well characterised cohort (the Raine Cohort), representative of the population of young adults in Western Australia. It will define the clinical picture and risk factors associated with abnormal breathing during sleep and will use the extensive longitudinal data collected from 18 weeks gestation until 23 years of age to quantify early life developmental and environmental pr ....This project will characterise Obstructive Sleep Apnoea (OSA) in early adulthood.

It will define the clinical picture and risk factors associated with abnormal breathing during sleep and will use the extensive longitudinal data collected from 18 weeks gestation until 23 years of age to quantify early life developmental and environmental predictors that can inform public health policy.Read moreRead less
Improving Long-term Mortality Rates Following Sepsis.
Funder
National Health and Medical Research Council
Funding Amount
$99,682.00
Summary
It is estimated that 37.9 million patients survive sepsis each year. Studies have demonstrated that among patients who survive for 30 days after admission for sepsis, over 40% die in the following two years. There are currently no guidelines that provide recommendations on post-hospital management of sepsis. This research programme aims to identify those patients at greatest risk of death and implement post-sepsis care with the aim to significantly reduce long-term mortality after sepsis.
Clinical Studies Of Diabetes And Tropical Infectious Diseases

National Health and Medical Research Council
Funding Amount
$568,892.00
Summary
The Fremantle Diabetes Study Phases I and II continue to make important contributions to our understanding of the natural history of diabetes and will be a major focus of the research supported by present application. Studies of malaria and severe bacterial infections in Papua New Guinean children that have regularly contributed to changes in national and regional treatment protocols will also continue under the supervision of the applicant.
We will investigate whether there are particular patterns of DNA methylation in people who develop gastric cancer. This could provide a means of identifying people at high risk of developing the disease, which may assist with early detection. This would be expected to markedly improve survival. If we can identify lifestyle factors associated with gastric cancer methylation there may be opportunities for prevention of the disease.
Longitudinal Communication Outcomes Following Traumatic Brain Injury

Funding Amount
$798,171.00
Summary
Traumatic brain injury (TBI) is the leading cause of disability in young Australians. The condition frequently manifests in impaired verbal communication. Communication is essential to successful rehabilitation, and return to society. However, the critical time for delivery of optimal treatment for communication remains unknown. This prospective longitudinal study will examine communication recovery following (TBI) to identify predictors of recovery and the best time to offer treatment.
