Summary
Asthma is the most common chronic lung disease of childhood. Birth cohort studies show that early life environmental stressors may increase asthma risk. This study will examine the impact of multiple early-life stressors using a novel ‘exposome’ model in international birth cohort studies, to identify the most significant factors. This will allow for interventions in a planned Australian birth cohort study, leading to improved health for Australians.
Diet Exercise And ARmodafinil For Obstructive Sleep Apnea (OSA) Patients Who Cannot Use Standard Treatments. (DEAR)

Summary
Obstructive sleep apnea (OSA) affects over 3.5 million Australians and is associated with marked daytime sleepiness and decreased concentration. It is also a common health complication of obesity. Many people are unable to use standard treatments for OSA in the form of a mouth splint or mask worn at night. This study will look at treating the daytime sleepiness with a stimulant medication, Armodafinil, whilst reducing OSA severity gradually with diet and lifestyle modification.
Ventilation Heterogeneity And Airway Remodelling In Asthma

Summary
Asthma is a common and important as a cause of significant symptoms and even death. Associated with asthma is narrowing and stiffening of the arways which causes uneven ventilation of the lungs and reduced lung function. We have developed a new technique of imaging the lungs, as well as new lung function tests which measure uneven ventilation and stiffening of airways. This will help us design better medications, and help predict those who are at risk or severe asthma and death.
The Role Of The Hedgehog Signaling Pathway In Asbestos Associated Malignant Mesothelioma

Funding Amount
$563,554.00
Summary
Mesothelioma is a aggressive asbestos related cancer mainly of the lung with no effective treatment. Evidence is pointing to the reactivation and aberrant expression of developmental signalling pathways such as the hedgehog signalling pathway as critical to the pathogenesis of certain types of cancer. This study will determine if mesothelioma is regulated by signalling through the hedgehog pathway and by blocking this pathway we will attempt to inhibit tumour growth.
An Education Intervention For Childhood Asthma By Local Aboriginal And Torres Strait Islander Health Workers

Summary
There are only a few studies on asthma in Aboriginal and Torres Strait Islander children, and those are restricted to prevalence and hospitalisation data. We have previously shown that the prevalence of childhood asthma in the Torres is similar to that of mainstream Australia and that children of this region generally have more severe asthma than children seen in urban areas.

We have previously shown that the prevalence of childhood asthma in the Torres is similar to that of mainstream Australia and that children of this region generally have more severe asthma than children seen in urban areas. Using a model of care appropriate for Aboriginal and Torres Strait Islander people, with the involvement of local Indigenous health care workers, we have adapted an asthma information package. With Study 1, we will examine the effect of local health care workers using this education package to educate children about their asthma. Our hypotheses is that children who receive additional asthma education by health worker have better asthma control. So we propose a randomized controlled trial of a culturally appropriate education intervention with children diagnosed with asthma. Enrolled children will be allocated by chance to one of the two regimes: (1) additional asthma education intervention: children will receive a personalised booklet (containing individual data eg. growth, photo of the child, health worker visits etc) that will be used during the medical consultation. They will also have 3 visits from the health worker for their asthma. (2) no additional intervention (they will receive usual information about asthma at the consultation and no health worker visit). With Study 2 we will examine the natural history of children with asthma and asthma-like symptoms and with symptoms suggestive of sleep breathing problems. Two groups of children previously seen by this team (5 years ago) will be clinically reassessed. Our hypothesis is that short to medium term history of asthma in Indigenous children in the Torres Strait is similar to non-Indigenous Australian children where there is a general improvement with age.Read moreRead less
The Interactions Between Sleep Disordered Breathing, Metabolic Syndrome And Vascular Risk.

Summary
We will look at two common diseases in the Australian community, the metabolic syndrome and obstructive sleep apnoea (OSA), and explore the common links they have to the risk of disease of the heart and blood vessels. We will then take a group of patients who have both diseases, treat the OSA, and assess the impact of this treatment on their cardiovascular health. Metabolic syndrome is a term given to patients who have high blood sugar, obesity, high lipid levels and raised blood pressure.

We will then take a group of patients who have both diseases, treat the OSA, and assess the impact of this treatment on their cardiovascular health. Metabolic syndrome is a term given to patients who have high blood sugar, obesity, high lipid levels and raised blood pressure. The Australian Bureau of Statistics estimates that half the Australian population is overweight, and US studies suggest that nearly of the adult population has metabolic syndrome. This is strongly linked to diseases of the heart and blood vessels, eg heart attacks and stroke. Patients with OSA stop breathing during the night when their throat closes over. The blood oxygen falls, which causes the patient to wake momentarily, then start breathing again. This cycle repeats itself throughout the night. The usual treatment is an air pump (CPAP) connected to a nose mask, which blows air into the throat and prevents closure. This disease is strongly linked to high blood pressure, raised blood sugar levels and heart and blood vessel disease. Patients with the metabolic syndrome will have an overnight sleep study to diagnose OSA, giving the likelihood of having OSA in this group of patients. They will then have extensive investigations of the health of their heart and blood vessels. From these, we will determine which aspects of OSA are more likely to result in cardiovascular disease. Those patients diagnosed with OSA will be treated with CPAP for 3 months. Half the patients will receive normal CPAP; the other half will receive ineffective CPAP. They will then be re-tested and we will compare the results before and after treatment. Thus we will measure likelihood of OSA in this large group of patients, and the health benefits they may gain from treatment of their OSA.Read moreRead less
