Funding Amount
$490,724.00
Summary
We aim to overcome a problem that is not being addressed by pharmaceutical companies- i.e., there is an urgent need to develop new classes of antibacterial drugs because of the increasing prevalence of drug resistant bacteria. We will combine genetics, structural biology and chemistry to develop a new class of anti-bacterial drug based on a naturally occurring microbial molecule that is novel in structure and very stable- attributes that make it very different to existing therapeutic approaches.

Summary
If fetal pig cells are to be of value in normalizing blood glucose levels in diabetic people once transplanted, they must survive and mature after being grafted. The pre-clinical study proposed will examine several novel issues that are of direct relevance to future clinical trials. The diabetic pig will be used as recipient to address when the fetal cell matures after it is transplanted, how long the grafted cells will maintain normal blood glucose levels, and at which site it is most appropria ....If fetal pig cells are to be of value in normalizing blood glucose levels in diabetic people once transplanted, they must survive and mature after being grafted. The pre-clinical study proposed will examine several novel issues that are of direct relevance to future clinical trials. The diabetic pig will be used as recipient to address when the fetal cell matures after it is transplanted, how long the grafted cells will maintain normal blood glucose levels, and at which site it is most appropriate to transplant the cells. The baboon will be used as recipient to address the safety of transplanting the pig cells, especially from the pig endogenous retrovirus, and whether the immunosuppressive regime proposed for use in humans will prevent cellular rejection. The diabetic baboon will be used in the final experiment step to determine if normalization of blood glucose levels can be achieved in this xenografted animal just as it can in the diabetic pig.Read moreRead less
Improving Medication Safety In Seniors: A Cross-Jurisdictional Linkage Project

Summary
The project will identify priorities for tackling the current epidemic of hospitalisation of Australians aged 65+ years due to side effects of their medications. Two different groups of medications will be investigated. The first will be the prescribed drugs most often recorded as causes of hospital stay, including those taken to stop blood clotting, for high blood pressure and other cardiovascular problems, for rheumatism or strong pain relief, anti-cancer drugs and steroids.

Two different groups of medications will be investigated. The first will be the prescribed drugs most often recorded as causes of hospital stay, including those taken to stop blood clotting, for high blood pressure and other cardiovascular problems, for rheumatism or strong pain relief, anti-cancer drugs and steroids. The study will examine which of these drugs taken under what circumstances has the highest risk, so prevention can be better targeted. The study will investigate if adequate laboratory monitoring of the anti- clotting drugs is taking place and whether the guidelines should be updated. The second group will be 68 medications that should be avoided in seniors according to an international expert panel. The research will see how often these 'inappropriate medications' are still prescribed in the Australian setting, and the size of their contributions to unplanned hospital stays. The researchers suspect that this problem is much larger than immediately apparent from routine statistics, because many of the side effects of inappropriate medications are non-specific, such as confusion, drowsiness or difficulty standing up, thus putting seniors at risk of falls and neglect of other aspects of their health. The study will use a unique and new Australian research facility, which has brought together health data on the entire population of WA from both the State and Commonwealth levels, including information on pharmaceuticals, Medicare use, hospital stays and deaths. The facility works in such a way as to preserve patient and GP privacy. A strong feature of this research will be the degree of involvement of a representative and voluntary group of older Australian patients who attend GP clinics, and the GPs themselves, in advising the researchers on what's important to consumers and GPs.Read moreRead less
Tracking The Impact Of Drug Regulatory Actions: Consumer Health Outcomes, Risk-benefit Issues And Policy Framework.
Funder
National Health and Medical Research Council
Funding Amount
$439,324.00
Summary
This study will explore what happens in the community when a medicine is withdrawn from the market or discredited due to safety concerns. It will examine the impacts of two recent cases of medicine withdrawal or serious long-term safety concern, on a large cohort of women with high utilisation rates who were monitored during the time the medicines were discredited. The study will be an important guide to future regulatory, media and provider responses when medicines are discredited.
A Sham-controlled Study Of Transcranial Direct Current Stimulation (tDCS) As A Treatment For Depression
Funder

Funding Amount
$423,154.00
Summary
This study tests the effectiveness and safety of a potential new treatment for depression, which involves mild stimulation of the brain, given through pads placed on the scalp. There is no anaesthetic or seizure and the treatment is painless. The treatment is given on an outpatient basis, three times per week, for 10 sessions, each session taking approximately half an hour. If found to be effective and safe, this new treatment could be an alternative to antidepressant medication.
Long-term Human Response Following Subretinal Injection Of Recombinant Adenoassociated Virus-sFlt-1 Vector
Funder

Funding Amount
$373,076.00
Summary
Age-related Macular Degeneration (AMD) is the major cause of blindness in the developed world. The present best practice for treating wet AMD is monthly injections of Lucentis� into the eye which is expensive, inconvenient for the patient and has increased risk of infection. The additional assays associated with the clinical trial will test whether adeno-associated virus-mediated gene therapy is safe and whether it can eliminate the need of multiple injections while delivering the same outcome.
Investigating Thermal And Possible Non-thermal Effects Of Radiofrequency Radiation In Brain Tissue

Summary
There are ongoing concerns over the possible harm from the prolonged use of mobile phone handsets. The WHO have issued a research agenda to address these concerns. This study aims to study possible mechanisms at the cellular level that was identified as a high priority research need. It aims to find out whether cellular changes that could be harmful follow as a result of slight heating effects within tissue, or whether some other, non-thermal, mechanisms may be involved.
Disturbances to the normal rhythm of the heart beat cause ~15% of deaths in our community. We wish to understand why the electrical signals in the heart can become chaotic. We will study a particular heart rhythm disturbance called acquired long QT syndrome to see if it is possible to develop a computer model that can accurately predict when and how arrhythmias will occur.

The use of ART is becoming increasingly frequent, with Australia having one of the highest rates of use internationally. Over 4,000 births result from ART annually in Australia. At the same time, minimally invasive infertility treatment-ovulation induction and insemination, remains a main option for some infertile couples and also generates several thousand births annually. A fundamental concern for those involved in infertility treatment is the health of the children born following the treatment. Evidence from many studies indicates that compared to the general population, ART babies are more likely to be a twin or triplet, have a low birth weight, be born premature, and suffer higher rates of perinatal death and cerebral palsy. These issues are gradually being addressed by transferring a single embryo in a cycle. Of greater concern is the recent reporting by a Western Australian team that the risk of major birth defects is doubled in ART children. This is a highly significant finding that has raised concern in patients and clinicians. It is imperative to verify the findings through replication in a larger study. It is equally important to identify whether the increased risk is due to potentially modifiable treatment factors or patient factors related to their infertility. This innovative study will therefore also separate patient characteristics and type of treatment, and partition the risk attributable to various factors. The health of children from infertility treatments is of fundamental concern and has become an important public health issue. This study will direct future basic research in embryology and clinical services where there is a continual need to balance technical innovation and efficacy with treatment safety. The long-term benefit will be improvement of the health status of Australian families.Read moreRead less
Evaluating The Safety Of Computer Decision Support Systems In General Practice
Funder
National Health and Medical Research Council
Funding Amount
$300,389.00
Summary
Use of clinical software has many benefits. However it is also likely that clinical software will introduce new computer-generated errors that may harm patients. This project will evaluate the safety of software for prescribing in general practice. We will firstly examine mechanisms for errors generated by clinical software on its own, and then in the hands of typical users. The outcomes will have broad potential to guide the regulation, use and design of clinical software in general practice.
