Paramedics are front line health staff and in the event of a pandemic will be among the first members of the community to face exposure to infection. This research will explore the attitudes and perceptions of paramedics and their families to working in epidemic conditions, provide prediction of behavioural responses to highly infectious environments, and a clear understanding of attitudes to infection control and use of Personal Protective Equipment (PPE). Knowledge of how to manage and support the responses of frontline health workers to an infectious disease outbreak is critical to the emergency system response. This project aims to mitigate the effects of perceived risk of infection on attitudes and behaviour of paramedics, by informing health promotion and infection-prevention messages to paramedics and their families. This research will also explore the emerging role of ambulance services as a key component of a public health surveillance system to provide an early warning of pandemic disease outbreaks and facilitate implementation of effective disease control strategies. Current triage systems, used for allocation of patients to appropriate treatment and-or quarantine, are not designed for epidemic environments, and may inadvertently facilitate disease spread and delay identification of victims requiring immediate care and-or quarantine. This project will explore the utility of a population-based triage tool to control an infectious disease outbreak by reducing patient-to-patient disease transmission. The project will facilitate expansion of current public health disease surveillance strategies and triage mechanisms for use during an epidemic, to effectively manage increased workloads within a highly infectious environment, whilst maintaining usual emergency medical services.Read moreRead less

This project aims to develop new methods, based on models and associated statistical analyses, to help ensure that our control programs are based on the best available evidence. There are five specific themes: 1. Developed methods for predicting major outbreaks of diseases and appy them to Australian data on measles, pertussis and Ross River virus. The new methods will enable timely intervention to reduce the population risk from these diseases, and to guide the proposed elimination of measles from Australia. 2. The current concept of vaccine efficacy, which is central to the epidemiological assessment of vaccines, performs poorly when the vaccine provides only partial protection, when immunity wanes over time and when infected vaccinees have a lower infectivity. A concept of vaccine efficacy will be developed that overcomes these weaknesses. This concept will find widespread use in epidemiology. 3. Data available from 80 outbreak investigations of transmissible diseases will be analysed to assess the relative effectiveness of various intervention steps. 4. A comprehensive model, and associated computer software, will be developed as a tool for assessing the relative merits of different vaccination schedules. It will be applied to address Australian policy issues for vaccination against pertussis, chickenpox and rubella. 5. The method of backprojection for estimating trends in HIV infection and predicting AIDS incidence will be enhanced to incorporate newly available data in which HIV and AIDS diagnoses are linked. This will enable a precise assessment of infection incidence among heterosexuals and other exposure categories with relatively few cases, to ensure that HIV does not spread more widely.Read moreRead less

Funding Amount
$645,205.00
Summary
Bacteria part of the Enterobacteriaceae family are responsible for causing significant enteric disease in Australia and internationally. Compounding the public health threat posed by these enteric bacteria is the rise in antimicrobial resistance, which limits treatment options. This project has three complementary research objectives; 1) to investigate new control strategies; 2) to better understand outbreak dynamics and; 3) to explore how bacteria are causing new disease in humans.

Summary
Salmonella is a leading cause of the food-borne disease – salmonellosis. It is responsible for considerable morbidity and has an enormous economic cost. Molecular typing is the key to rapidly identify and control outbreaks. This project will optimise the use of whole genome sequencing for outbreak investigation and long term epidemiology. A surveillance system that integrates genome sequence and epidemiological data will be highly significant for outbreak investigation and disease prevention.

Summary
One of the most difficult and clinically important questions facing clinicians treating advanced cancer is deciding which patients will, and who will not, benefit from chemotherapy and-or radiotherapy.

This is particularly true for clinicians treating locally advanced oesophageal cancer. Oesophageal cancer is a particularly aggressive tumour with a poor prognosis; the majority of patients die within 1 year of diagnosis with only 10% surviving to 5 years. In an attempt to improve outcomes, the use of preoperative (neoadjuvant) combined chemotherapy and radiotherapy as an adjunct to surgery has become common practice. Neoadjuvant therapy has been reported to induce complete regression of the tumour and increased survival times in 20-30% of patients. However, the lack of any apparent clinical benefit for those patients who are poor or non-responders to chemoradiation implies that a large proportion of patients are being exposed to significant toxicity and potential complication for no obvious advantage. In the project outlined in this application, we propose to use cDNA microarrays, a technology that allows the simultaneous assessment of the level of expression of thousands of genes at once, to profile the gene expression patterns of oesophageal tumours. These profiles will then correlated to the patients response to treatment to determine if the gene expression patterns can be used to predict the clinical response to chemoradiotherapy. Success will open the path to the development of a clinically important test that would significantly improve the management of advanced cancer patients by enabling personalised therapy for individual patients. Not only will this allow the selection of the most effective therapy for each patient but it will also free patients from suffering the nasty side effects of treatments that turn out to be of little benefit.Read moreRead less

It is a common cause of fatal pneumonia and blood infection in the region. This project builds on the existing melioidosis collaboration between researchers in northern Australia and overseas. The aim is to use new DNA fingerprinting methods developed specifically for the melioidosis bacteria to understand better why melioidosis can be such a severe disease and how it spreads from the environment to humans and animals and also how it has possibly spread within Australia and overseas. Our studies in the Darwin rural region have found an alarmingly high rate of contamination of bore water with the melioidosis bacteria. We need to evaluate further the magnitude and public health implications of this contamination. Better recognition and treatment of melioidosis has resulted in a halving of the death rate from this disease in northern Australia (mortality decreased from 40%-15%). This study also aims to develop and test a new DNA detection system for rapid diagnosis of melioidosis. This will enable even earlier intervention with treatment specific for melioidosis which will hopefully decrease the mortality further.Read moreRead less

It is a common cause of fatal pneumonia and blood infection in the region. Two outbreaks of melioidosis with fatalities occurring in remote Aboriginal communities have been linked to contamination of the community water supply with the melioidosis bacteria, Burkholderia pseudomallei. In addition, a rare form of melioidosis affecting the brain and spinal cord has resulted in a number of deaths in healthy Aboriginal people and also a number left living in remote communities with severe disabilities such as complete paralysis of both legs. Melioidosis has also been identified in two outbreaks occurring over many years in separate locations in southern Australia. It is thought that it may have been introduced to these regions by imported animals, eg via cattle drives, and human fatalities have occurred after local flooding in these temperate locations. This project is built on the ongoing melioidosis collaboration between researchers in Western Australia, the Northern Territory and Queensland. The aim is to use new DNA fingerprinting methods developed specifically for the melioidosis bacteria to understand better why melioidosis can be such a severe disease and how it spreads from the environment to humans and animals and also how it has possibly spread within Australia and overseas. Better recognition and treatment of melioidosis has resulted in a halving of the death rate from this disease in northern Australia (mortality decreased from 40%-18%). This study aims to give us a better understanding of how this soil and water bacteria interacts with humans to cause such severe disease and will hopefully result in new primary preventative measures to complement the improved diagnosis and treatment.Read moreRead less
