$4,647,175.00
Summary
As we become older and risk factors such as obesity become more common, our biggest contributor to death and disability, cardiovascular disease (including heart disease), will continue to exert an enormous burden on our health care system and society. We will extend our ground-breaking research on multidisciplinary teams to create new and innovative health care programs to optimise the prevention and management of new heart disease and chronic forms of heart disease.
STudy Of Risk Assessment To Reduce Complications In Patients Following Noncardiac SurgerY (STRATIFY)

Summary
Cardiac problems account for many complications in patients undergoing major non-cardiac surgery, and even apparently minor cardiac damage is a marker of high risk for subsequent adverse events. Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear.

Unfortunately, while money and effort is expended on identifying patients at risk, the appropriate response to this risk is quite unclear. The performance of bypass surgery or balloon angioplasty in order to treat the underlying coronary disease of at-risk patients is used in other situations, and reduces longterm risk. However, in many patients undergoing major noncardiac surgery, this approach may be inappropriately aggressive, as these patients are often elderly, have other diseases that make heart operations more difficult and risky than usual, and in any case may have a reduced life expectancy from the disease necessitating the operation. As the most critical issue is to ensure that patients undergo their surgery uneventfully, an alternative is the use of intensive medical therapy to protect the heart. This multicentre study, based at Brisbane hospitals that perform large numbers of major operations, will follow up patients for complications, and outcome (including quality of life) will be assessed six months after the operation. We will address two important questions about the efficacy and cost of risk reduction strategies. First, in patients at higher levels of risk and with a positive stress test, could a combination of medical therapy designed to protect the heart be as effective as current approaches, which include the performance of bypass surgery or coronary balloon angioplasty? Second, in patients identified as being at some risk - but low risk - are drugs sufficiently effective to avoid the need for further testing to quantify risk? As the population continues to age, the numbers of at risk patients undergoing major surgery will increase, and answers to these questions will provide important information to guide their management.Read moreRead less
A National Population-based Study Of Rheumatic Heart Disease In Pregnancy

Funding Amount
$877,826.00
Summary
Whilst overall a rare disease, Indigenous peoples have disproportionately high rates of rheumatic heart disease (RHD). This study explores the prevalence and distribution of RHD in pregnancy in Australia and New Zealand. It details current management, diagnostic and referral process and risk factors. Key attributes of culturally safe models of care for RHD in pregnancy are explored, particularly as they relate to Indigenous women. Findings will inform policy, guidelines and education resources.
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Funding Amount
$729,571.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
Benefit Of 2D-strain Surveillance In Improving Cardiovascular Outcomes In Cancer Patients Undergoing Cardiotoxic Chemotherapy
Funder
National Health and Medical Research Council
Funding Amount
$2,391,979.00
Summary
Cancer survivors are susceptible to heart failure (HF) caused by heart muscle damage from chemotherapy. The current testing for this problem is based on a measure that cannot identify minor changes of cardiac function. Cardiac strain is a sensitive new marker of cardiac function which is predictive of overt dysfunction & HF. This study seeks to identify whether strain can be used to assign treatments that lead to improved cardiac function and are eventually associated with a reduction in HF.

Summary
Many forms of pain remain poorly treated, leading to significant quality of life and economic losses. This Program grant will discover and characterise new peptides from cone snails and spiders that modulate specific channels in nerves that are critical to the transmission of pain signals to the brain. Using advanced chemical and structural approaches, promising leads will be optimised for potency and stability and evaluated in disease and pathway-specific models of pain to establish their clini ....Many forms of pain remain poorly treated, leading to significant quality of life and economic losses.

Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport).

Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport). The project will provide fundamental advances in our knowledge of the nutrient transport during pregnancy that is required to produce a healthy baby.Read moreRead less
CKD-FIX: A Randomised, Controlled Trial Of Allopurinol In The Slowing Of Kidney Disease Progression
Funder
National Health and Medical Research Council
Funding Amount
$1,917,147.00
Summary
Chronic kidney disease (CKD) is a major public health problem affecting over 1.5 million Australians and is associated with increased risk of death, heart disease and progression to end-stage kidney disease (ESKD). Current treatments to slow progression to ESKD are limited. The CKD-FIX trial aims to find out whether treatment with allopurinol, a commonly used drug for gout prevention, safely and effectively slows CKD progression. This could lead to significant health and economic benefits.
Optimising the spring in your step to enhance footwear design. This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world.

This project aims to examine how the nervous system adjusts the mechanical function of our feet across a spectrum of speeds, from slow running through to maximal effort sprinting. The proposed research will explore how the nervous system controls the function of the foot to meet the ever-varying demands of locomotion in the real-world. Expected outcomes of this project are to determine if running shoes help or hinder the natural spring-like function of the foot. It will explain a conceptually novel design allowing shoes to support our feet, whilst harnessing the energetic benefits of the foot's spring-like function. This research has the potential to revolutionise athletic footwear design and has direct implications for enhanced performance in running athletes.Read moreRead less

This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size distributions from tropical to polar environments are expected to reveal these vital rates of pelagic ecosystems. The zooplankton rates will reveal, for the first time, the link between phytoplankton and fisheries, and will significantly improve ecosystem models and global assessments of environmental change.Read moreRead less
