Summary
Lung cancer is the third leading cause of death in Australia. People with lung cancer experience a complex mix of symptoms that can provoke significant distress and impair physical function. This study aims to develop and test a home based exercise and self-management support program to increase function and physical activity levels, reduce levels of depression and improve quality of life of people with lung cancer.
This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrat ....This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrate, typical of many Western countries, inevitably requires the ingestion of additional energy to maintain protein intake constant, thus driving weight gain. Conversely, the consumption of a diet that is relatively high in % protein requires the ingestion of lower levels of energy, creating the potential for weight loss. Preliminary experimental and population-level nutritional survey data support the PLH, as does the finding that protein is more satiating than other macronutrients. If, as predicted, small changes in the proportion of protein in diets described in the current study are found to impact on total energy intake there will be significant implications for weight control strategies. Thus, if the PLH is confirmed, public health dietary recommendations and government policy settings for the food industry will need to change. Large-scale intervention studies aimed at demonstrating the longer term impact on body weight will also be required.Read moreRead less
Targeting PI3K-regulated MicroRNAs To Treat Heart Failure

Summary
Current therapeutics largely delay heart failure progression rather than regressing it. New therapeutic strategies with the capability of improving function of the failing heart are thus greatly needed. The primary goal of this study is to determine whether novel regulatory genes can enhance cardiac function in a setting of heart failure. Ultimately, technologies that target these genes may lead to innovative pharmacotherapies in the clinical management of heart failure.
Optimal Duration Of Neoadjuvant Androgen Deprivation Therapy In Localised Prostate Cancer

Summary
Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer ....Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer of the prostate that has spread throughout the body for the last five decades, worldwide. It remains uncertain however whether AD administered before surgery or radiation will benefit any of the 8000 men each year who develop localised cancer by shrinking the cancer first. In 1996 a trial involving 800 men across Australia and New Zealand commenced under the auspices of the Trans-Tasman Radiation Oncology Group (TROG) to answer the questions: 1 - Does either 3 or 6 months AD prior to radiotherapy reduce the chances of recurrence of the cancer after radiotherapy? 2 - Does such therapy reduce the volume of tissue requiring radiotherapy and hence the chances of long term side effects after radiotherapy? This grant will support collection of follow-up information from the trial and hence answers to the questions asked.Read moreRead less
I-HEART - Implementation Of HEArt Failure Guidelines In Regional AusTralia
Funder
National Health and Medical Research Council
Funding Amount
$1,266,173.00
Summary
Heart failure (HF) is a common disease of the heart with a high rehospitalisation and mortality rate. Regional HF patients rarely receive the full benefits of evidence-based care simply due to inaccessibility to a HF specialist team. This translational project will implement key recommendations from clinical guidelines in regional health services and improve access to specialist services. It has the potential to keep patients out of hospital and save lives.
Central Aortic Blood Pressure In Children: Establishing A Gold Standard Non-invasive Assessment Of Cardiovascular Risk
Funder
National Health and Medical Research Council
Funding Amount
$694,342.00
Summary
The best way of assessing early risk of cardiovascular disease involves measuring blood pressure near the heart (central pressure), but existing devices used in adults for this purpose are inaccurate in children. We will develop a children-specific method and apply it to study early cardiovascular risk in a comprehensive health study of 2000 children Australia-wide. We will also investigate why children with congenital heart disease frequently develop ‘older-adult’ heart disease at a young age.
Advanced Heart Failure Management With Ventricular Assist Therapy – Evaluating Australian Costs Of Care And Effectiveness From Implant To Transplant Or End Of Life

Funding Amount
$45,668.00
Summary
Ventricular Assist Devices (VADs) are implantable heart pumps that are increasingly being used to slow down the progression of end stage heart failure. This project assesses the costs and effectiveness of VAD therapy and advanced heart failure medical management in an Australian health care setting. The aim is to provide Australian clinicians and health decision makers access to current and relevant, clinical, cost and effectiveness data for advanced heart failure and VAD therapy.
Optimal Source Control in Urban Water Cycle Management. Major opportunities exist to improve the management of the urban water cycle by better use of source control technology such as the use of rainwater tanks and water-sensitive design. This program will optimise the use of this technology at three scales, allotment, subdivision and regional, using genetic algorithms, parallel computing and shadow pricing.

This program will optimise the use of this technology at three scales, allotment, subdivision and regional, using genetic algorithms, parallel computing and shadow pricing. The aim is to minimise community lifecycle costs subject to sustainable use of ecosystems and maintenance of public health standards. The benefits include national savings of the order of $2 billion and significantly reduced demand on water supply and stormwater infrastructure and its supporting ecosystems.Read moreRead less
Modelling long-term hydrological persistence using hidden state Markov models. Long-term climatic persistence has a pronounced effect on engineering risk assessment of drought and flood severity.

Long-term climatic persistence has a pronounced effect on engineering risk assessment of drought and flood severity. Accurate risk assessment is essential for economic design of water resource and flood defence infrastructure. A new, physically realistic, framework for stochastic modelling of persistence is developed, in which the probability distributions of hydrological variables depend on underlying climatic states. These states are not directly observable, and occasionally change in a random manner. The research program, involving three PhD projects, will develop: estimation techniques and software using climate indices and multi-site data; a new approach to flood risk regionalisation; and seasonal rainfall forecasting methods.Read moreRead less
