Burden Of Rheumatic Heart Disease (RHD) And Impact Of Prevention Strategies: Comprehensive Evidence To Drive The RHD Endgame
Funder

Funding Amount
$960,655.00
Summary
Rheumatic heart disease is chronic damage to the heart valves caused by repeated bouts of acute rheumatic fever. Both are preventable, yet rates among Indigenous Australians are of the highest recorded. We propose to undertake the first multi-jurisdictional study of these conditions to determine trends in occurrence and evaluate the impact of existing interventions in Australia. Findings will be used to inform the development of a roadmap to remove RHD as a public health problem in Australia.
Management Of Breathlessness. Cognitive Behavioural Therapy For People With Chronic Obstructive Pulmonary Disease (BREVE RCT)

Funding Amount
$402,875.00
Summary
For people with chronic lung disease, breathlessness is common, distressing and difficult to relieve. Pulmonary rehabilitation programs have been demonstrated to improve exercise capacity and quality of life. This study will determine whether changing the way people think about the sensation of breathlessness while completing pulmonary rehabilitation, further reduces distress/anxiety and health service use and improve exercise capacity, disability related to breathlessness and quality of life.
Pregnancy And Neonatal Diabetes Outcomes In Remote Australia (PANDORA) Cohort

Funding Amount
$2,395,410.00
Summary
The PANDORA study is a longitudinal birth cohort study recruited from a clinical register of Northern Territory women with diabetes in pregnancy (DIP). We will also recruit a comparator group of mothers without DIP and babies. Follow-up of mothers and infants to 3 years post-delivery will be from medical records, questionnaires and clinical assessment. Rates of progression to type 2 diabetes will be assessed among mothers, and growth, feeding patterns and diabetes risk markers among infants.
Using MiR-200 To Find New Therapeutic Targets For Neuroblastoma

Summary
Neuroblastoma is one of the most common cancers in children. We have found that a genetic regulator, called microRNA, can limit the ability of neuroblastoma cells to invade surrounding tissues and metastasise. We aim use the microRNAs to find new therapeutic targets that may work in combination with existing treatments, reducing the short term toxicity and long term deleterious effects of current treatments.
A Novel Metabolic Role For UDP Glycosyltransferase 8 (UGT8)

Summary
The UDP glycosyltransferases (UGTs) are a family of enzymes that remove drugs and toxins from the human body as well as control levels of naturally produced molecules such as bile acids and hormones. We found that a new member of this family called UGT8 processes bile acids in the kidney and intestine and can affect how bile acids act to regulate metabolism. Our studies uncover new roles for bile acids in liver, kidney and gut health and in metabolic disorders such as diabetes and obesity.
How IsomiRs Expand The MicroRNA Functional Repertoire In Affecting Gene Expression

Summary
MicroRNAs function as regulators of gene expression. It is becoming appreciated that microRNAs are frequently expressed as variants with subtly different sequences. We find here that variation in one important cancer-associated microRNA, miR-222, promotes differences in the behaviour of cells expressing them. This work seeks to understand how microRNA variation confers such properties to cells, to identify the genes miR-222 variants regulate, and to examine how widespread it is that microRNA var ....MicroRNAs function as regulators of gene expression.

How Does Dietary Cholesterol Induce Non-alcoholic Steatohepatitis?

Funding Amount
$802,600.00
Summary
Non-alcoholic fatty liver disease is the most common liver disease that can progress to non-alcoholic steatohepatitis (NASH), cirrhosis and liver cancer. Dietary cholesterol is a major risk factor for NASH. We can demonstrate that cholesterol changes the gut bacteria. These bacteria generate toxic chemicals (bile acids) that signal to the liver and induce NASH. In this project, we use novel ways to clarify the mechanisms of liver inflammation and test novel therapeutic approaches to reverse it.
A Randomised Controlled Trial (RCT) Of Azithromycin Versus Doxycycline For The Treatment Of Rectal Chlamydia Infection In Men Who Have Sex With Men.

Funding Amount

Summary
Rectal chlamydia is very common among gay men; it can exist for long periods without symptoms leading to ongoing transmission. Azithromycin (1 gram single dose) or 7 days doxycycline (100mg twice daily) are the two recommended treatments globally. But, there is concern about rectal chlamydia treatment with reports of up to 22% failure following azithromycin. We will conduct a randomised trial to compare these treatments for rectal chlamydia and determine which drug works better.
Irritable Bowel Syndrome (IBS) is one of the leading causes of chronic pain both world-wide and in Australia for which there is a lack of treatments. Chronic pain arises from nerve fibres in the colon wall, which fail to 'reset' back to normal following inflammation. Targeting these nerve endings with drugs is a key advance in IBS treatment. This project will identify selective oxytocin analogues that act in the colon to lower pain in sensory nerves thus providing efficacious pain relief in IBS.
Identification Of The Conformation Dependant Targets Of Autoimmune Disease Linked Variation In Human Regulatory T Cells

Funding Amount
$1,001,815.00
Summary
Specialised immune cells called regulatory T cells act as the policemen of the immune system, preventing the immune system attacking itself, but still fighting infections. If these cells do not work properly, autoimmune diseases such as type 1 diabetes or IBD can arise, because of immune attack on normal body tissue by mistake. In order to explain how this goes wrong we need to carefully identify all of the gene interactions in these cells including interactions over long distances in the DNA.
