Summary
It is well known that major burns, as well as being relatively common injuries, are notoriously difficult to manage. Patients exhibit significant variability due to a combination of anatomic, physiologic, hormonal and immunologic alterations occurring both at the wound site and, more importantly, in other body compartments and vital organ systems. Skin burn injury results in the release of multiple inflammatory mediators in addition to significant fluid loss.

Patients exhibit significant variability due to a combination of anatomic, physiologic, hormonal and immunologic alterations occurring both at the wound site and, more importantly, in other body compartments and vital organ systems. Skin burn injury results in the release of multiple inflammatory mediators in addition to significant fluid loss. The distribution of inflammatory mediators and wound bacteria to central organs can cause complex physiological changes that may lead to multiple organ failure, with serious infections occurring in around 50% of patients with serious burns. Antibiotic distribution kinetics, such as bioavailability, clearance, volume of distribution, elimination half-life and unbound fraction in plasma can be significantly altered in burn patients. Without detailed knowledge of changes and relationships between factors such as wound pH, tissue oxygenation, protein concentrations of fluid leaked from the local wound microvasculature, tissue binding, oedema and changes in burned and non-burned tissue induced by resuscitation therapies, the optimisation of both local and systemic infection contriol therapies can hardly be expected to advance. This project aims to determine how changes the physiology of burn patients, in particular in the burn wound environment, affect antibiotic penetration and distribution into tissues. We also believe that these changes will vary between patients and are aiming to determine whether certain parameters can be used to give an indication of the best antibiotic dosing regimens for individual patients.Read moreRead less

Improving Access To Optimal Clinical Care For People With Chronic Hepatitis B Through The Implementation Of A Nurse-led Model Of Care

$176,250.00
Summary
Chronic hepatitis B (CHB) is a global public health issue. Best practice guidelines indicate that early diagnosis and treatment can reduce mortality, however, guidelines are not being followed because uptake of management and treatment is low. This project aims to address the gap between optimal and current CHB management through implementation of a nursing service, which will build capacity, and target the need for improved management for this vulnerable group of patients.
Translation Of Abdominal Functional Electrical Stimulation From A Research Tool To Clinical Practice

Funding Amount
$318,768.00
Summary
People with a spinal cord injury to the neck are often unable to move their arms and legs, a condition known as tetraplegia. Tetraplegics are also unable to use their abdominal muscles, reducing breathing and bowel function. This project will use electrical pulses to make their abdominal muscles contract, improving breathing and bowel function. The results will be used to develop a program that can be used in all hospitals, reducing illness in tetraplegia and saving the health service money.
Next Generation Of Medical Devices And Diagnostics

Funding Amount
$2,738,220.00
Summary
This Investigator Project will deliver innovative technologies that improve patient wellbeing, make significant economic impact and contribute to answering complex biological questions. This will happen via delivering breakthrough technologies to prevent infections and diagnose diseases – two area that currently require substantial technological advances. In addition to helping patients and clinicians, the project will also deliver solid body of new knowledge that is currently missing.
Clinical Impact Of Clonal Pseudomonas Aeruginosa In Cystic Fibrosis

Summary
In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on ....In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on the major bacterial problem, Pseudomonas aeruginosa. Several studies from Australia and the UK, including our own have shown that about 30% to 45% of patients share the same strain of Pseudomonas aeruginosa within a centre. We know that two dominant strains of Pseudomonas aeruginosa are found in CF centres on the eastern board of Australia. This is unexpected as this bacterium is usually acquired from the environment. The emergence of these clonal strains is causing increasing anxiety in the CF community. This study is designed to provide vitally needed information on the clinical implications of being infected by an clonal strain of Pseudomonas aeruginosa and the risk factors for the acquisition of an clonal strain. This new information will provide a rationale basis for the need for changes to infection control policies (including patient segregation), better outcome predictors for patients infected with clonal strain of Pseudomonas aeruginosa.Read moreRead less
Treatment Of Cerebral Palsy - An Experimental Approach

Summary
Cerebral palsy is characterised by disordered movement evident early in life leading to lifelong disability. The motor disorder arises from an abnormality within the white-matter of the brain that is non-progressive and is identifiable soon after birth. In humans and experimental models of fetal infection there is an increase in markers of inflammation. We will use induce ovine fetal infection and white matter injury to examine if anti-inflammatory treatments can prevent fetal brain damage.
Mechanisms Regulating Establishment Of Persistent Herpesvirus Infection

Summary
Herpesviruses are a major cause of disease worldwide and are amongst the most successful human pathogens, with some viruses infecting more than 80% of the world's population. This group of viruses persist and reactivate in hosts and induce immunosuppression.The control of herpesviruses infections thus represents an important clinical goal. Understanding the mechanisms involved in the induction of viral persistence and immunosuppression is a crucial step towards developing better therapies.
Determinants Of Cytomegalovirus Salivary Gland Persistence

Summary
Human cytomegalovirus (HCMV) persists for extended periods in the salivary gland, an organ of viral transmission. It is not clear how the virus avoids immune mediated control in this tissue. This aspect of viral pathology will be assessed in a mouse model using two strains of murine CMV which exhibit marked differences in salivary gland persistence. The role of tissue tropism (inhibition of apoptosis), viral immune evasion and host immunity in salivary gland persistence will be studied.
Cluster Randomised Trial Comparing One Versus Two Doses Of Ivermectin For Mass Drug Administration To Control Scabies

Summary
Scabies is a common skin disease in developing countries, in particular in the Pacific region. In the Western Province of Solomon Islands, one in two children suffer from the infestation, and 20% of the population. We know that mass drug administration with two doses of oral ivermectin is effective to reduce the burden of scabies in the community. We now propose a study to determine whether one single dose is as effective. This would have major public health benefits.
