Summary
Lung infections such as pneumonia are common in Indigenous children, and can lead to repeated hospitalisation and permanent lung damage. They are also an important cause of preventable death in children. This study will look at the role of bacteria and viruses in lung infections, and will inform interventions to reduce the burden and consequences of lung infections in Indigenous children.

Summary
Over 3000 newly born infants require mechanical ventilation in Australia every year. The majority are very premature infants. About 30% of ventilated infants develop serious ventilator induced lung injury. Minimising such lung injury with improved techniques of ventilation which can protect the lung from injury will reduce the considerable short and long term health burden of this population.

Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
Postviral Wheezing In Childhood: Disregulation Of Airway Tone?

Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens.

Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less
The Clinical Utility Of Small Airway Function Tests In Paediatric Respiratory Disease

Funding Amount
$64,631.00
Summary
Respiratory disease is an important child health issue with long term implications into adulthood. The evaluation of small airways involvement in disease processes, using an accurate sensitive measures of function, such as forced oscillation technique and multiple breath washout, potentially facilitates not only early detection of disease, but instigation of earlier treatment, better assessment of response to treatment, and ultimately better outcome.
The health effects of electronic cigarette use are virtually unknown. They have only recently been introduced into widespread use, and as such their effects on human health will not be known for many years. We will use our expertise in exposure models and health outcome measurement to provide timely hard-data on their potential to impact health – data that are urgently required to guide policy makers in this area.
How Do Thick Airway Walls Affect Airway Hyperresponsiveness In Asthma?
Funder

Funding Amount
$382,538.00
Summary
Asthmatic airways narrow too easily, a characteristic called airway hyperresponsiveness (AHR). To understand the cause of asthma we need to understand the cause of AHR. Thickened airway walls could amplify airway narrowing and increase AHR. However, thick airway walls are also stiff, and stiff walls could reduce narrowing and AHR. This project will examine the relationships between AHR and airway wall thickness and stiffness during and after treatment that reduces airway wall thickness.
Inhibition Of IFN-?/? By Human Metapneumovirus And The Induction Of Inflammation

Funding Amount

Summary
The newly isolated human metapneumovirus (hMPV) causes significant respiratory illness in infants, young children and the elderly. The virus can persist long-term and may predispose individuals to chronic lung disease. This proposal aims to determine the mechanisms by which hMPV infection causes respiratory disease, with a view to improving treatments and preventing disease.

A newly discovered respiratory virus, human metapneumovirus (HMPV), causes clinical disease that is very similar to human respiratory syncytial virus (RSV) and co-circulates with RSV.

Human RSV is a major cause of morbidity and life-threatening respiratory tract disease in infants and young children worldwide, and is recognised as an important respiratory pathogen in elderly adults and immune compromised patients. The recent isolation of HMPV from children hospitalised with respiratory tract illness similar to RSV, but with an unknown etiology, suggests that HMPV may mediate similar clinical pathology. Nothing is currently known about the immune response to HMPV, or the association of these responses with lung disease. The objectives of this proposal are to elucidate the mechanisms of immunity and disease pathogenesis associated with human metapneumovirus (HMPV) and to investigate the use of a novel vaccine to protect against HMPV infection. Once this data is obtained, the study will provide the foundation for further research in the development of vaccines or therapeutic protocols to treat HMPV. It will also provide valuable information for understanding the disease in humans. Also,it is likely that HMPV, like hRSV, may prove to be an agent associated with long-term decreased pulmonary function and airflow limitation perhaps developing to asthma.Read moreRead less
A Randomised Controlled Trial Of Interventional Versus Conservative Treatment Of Primary Spontaneous Pneumothorax

Funding Amount
$412,315.00
Summary
Primary spontaneous pneumothorax (PSP) is a collapsed lung that occurs in otherwise healthy people without underlying lung disease. Current standard treatment is to insert a chest drain into the chest to remove the air around the collapsed lung so that the lung re-inflates rapidly ("interventional treatment"). We will determine whether doing nothing, i.e. letting the lung re-inflate slowly on its own over several weeks ("conservative treatment"), is just as good or even better for patients.
