Summary
This project will improve our understanding of the causes of chronic respiratory diseases (CRDs) in adults. CRDs are clearly a major public health problem, but there are no good data on the natural history and risk factors for these diseases. Regular follow-up through childhood to adulthood is the best method to examine these factors, but such data is lacking due to difficulties in conducting long-term studies.

CRDs are clearly a major public health problem, but there are no good data on the natural history and risk factors for these diseases. Regular follow-up through childhood to adulthood is the best method to examine these factors, but such data is lacking due to difficulties in conducting long-term studies. The Tasmanian Asthma Study (TAS), based on 8,585 Tasmanians (i.e. probands) born in 1961, is one of the worlds most important resources of such information. The probands, their parents (16,267) and siblings (21,044) were first investigated for respiratory problems in 1968. Subsequently, three follow-up surveys were carried out at ages 13 (1974), 20 (1981) and 31 (1992) on either the total or sub-samples of the probands. In 1992, the children and spouses of the probands were also surveyed. Information on all respiratory problems was collected in all the follow-ups, although the main focus of the TAS to date has been asthma. The probands are now reaching the age at which all CRD as a group are beginning to inflict an increasing disease burden, which will become greater in the next two decades. Hence, TAS now provides an ideal opportunity to examine the potential risk factors and natural history of and of CRDs using data collected to date and new data collected at age 43. Also, it will provide a platform for future studies to investigate the progression of CRDs in this cohort. Hence, we propose to carry out the 36 year follow-up of this cohort focusing on CRDs. This will provide important information for preventing chronic respiratory morbidity and disability in the future, which will be original and significant not only in Australia but also internationally.Read moreRead less
This project will take robust evidence regarding inflammation based management, comorbidity and self management and translate it into practice using a national implementation framework.
Equitable Access To Stuttering Treatments: Developing Distance And Self Managed Treatment Models

Summary
The development of normal verbal communication is of the utmost importance to human health. Stuttering is a prevalent disorder that severely interferes with communication. It can be disfiguring and typically causes speech related social anxiety. Social phobia is present in around half of adults affected. It prevents attainment of occupational potential and children who stutter are typically teased and bullied at school.

Stuttering is a prevalent disorder that severely interferes with communication. It can be disfiguring and typically causes speech related social anxiety. Social phobia is present in around half of adults affected. It prevents attainment of occupational potential and children who stutter are typically teased and bullied at school. For the past decade NHMRC Project funding has enabled the present team to conduct world class basic research and clinical trials in stuttering. Significant gains have resulted from that research, in particular the development of treatments across the age groups that have a significant evidence base. However, it is becoming increasingly clear that there are serious barriers to the implementation of these evidence based treatments, and innovative treatment developments are needed to address this. In particular, speech pathology services for rural and remotely located patients and their families are incompletely funded, and even in urban settings workplace restrictions have resulted in speech pathologists delivering incomplete and piecemeal treatments. The program of research will develop the following innovative treatment models to solve this problem: �Distance intervention models for the delivery of speech pathology services to rural patients and their families and others who are isolated from treatment services. �Self-managed treatment models for children and adults who stutter, including procedures to minimise the ubiquitous problem of relapse in adults. It is widely understood that social anxiety is a significant problem for many stutterers and research is urgently needed to establish the extent of social anxiety in stutterers across the age groups and its negative effects on treatment effectiveness. Thus, a further aim of this program of research is to: �Identify those patients for whom social anxiety is likely to constitute a barrier to successful treatment. �Develop supplementary interventions to meet the needs of those socially anxious patients. The cause of stuttering is unknown. Understanding the mechanisms underpinning effective behavioural treatments would contribute to understanding causal factors in stuttering. Thus, this program of research also aims to: �Establish why behavioural treatments work, thereby generating new knowledge about causal factors.Read moreRead less
Localised Airway Reactivity As A Determinant Of Asthma Control And AHR

Summary
Asthma morbidity and mortality remain high, with drug cost, days lost from school and work. This may be due to severe asthma in which control cannot be attained. This may be due to localised regions of lung that remain persistently responsive to inhaled irritants. We will examine the location and size of these regions using 3-dimensional ventilation scanning. The potential importance of our findings is in providing a basis for improving treatment in resistant, severe asthma.
Centre Of Research Excellence In Asthma Treatable Traits (CREATT)

Funding Amount
$2,500,000.00
Summary
This CRE will focus on personalised medicine in asthma, specifically using the treatable traits approach. We have identified disease management areas of highest importance to people with asthma and health care providers. We will generate new knowledge, develop and strengthen collaborations and train translation focused researchers to develop high quality evidence and translate this to practice.

Summary
Severe Asthma remains a large burden for the Australian community. It does not respond to current management approaches. We will develop and implement a targetted therapy approach to severe asthma that will involve assessment of needs of people with severe asthma, community burden form severe asthma, biomarkers and linked treatment strategies, as well as knowledge transfer tools and training of the health and medical workforce.
Elucidating The Roles And Mechanisms Of Activation Of NLRP3 Inflammasomes And Developing Therapeutic Interventions For Severe Steroid-resistant Asthma

Funding Amount
$961,929.00
Summary
Severe asthma is a major clinical issue. There are no effective treatments because we don’t understand how it occurs. We have identified a factor called an “inflammasome” that we think causes severe asthma. We have produced a new inhibitor of this factor, and shown experimentally that it may suppress important symptoms of severe asthma. We now aim to work out precisely how this inflammasome causes severe asthma and progress our new inhibitor towards therapeutic development.
Targeting Neutrophil Extracellular Traps To Reduce Inflammation In Severe Asthma
Funder
National Health and Medical Research Council
Funding Amount
$585,240.00
Summary
People with severe asthma, a chronic disease of the lungs, often have many inflammatory cells in the airways called neutrophils. Neutrophils release a meshwork of fibers in a web like trap called NETs, which are made of the cells DNA and other proteins that fight infection. These NETs can promote inflammation in the persons airways. Current asthma treatments have no effect on NETs. This project will measure NETs in the airways and test a new treatment to reduce NETs, and relieve asthma symptoms.
