Summary
We have shown that a potassium channel known as hERG falls precipitously at the time of term labour and that blocking this channel causes powerful uterine contractions. This grant will determine how the expression of this channel is regulated in the myometrium and whether changes in hERG channels also occur in premature labour.
Understanding The Myometrial Transition At Term And Preterm Labour To Guide Tocolysis

Summary
This grant seeks to understand how the muscle cells of the uterus transform at the time of labour. We propose that this transformation is organised by enzymes that modify the histones around key genes. We will test if a similar pathway operates in cases of preterm labour. The results will guide the development of new ways of treating premature labour that will use targeted nanoparticles to deliver siRNA directly to the muscle cells of the uterus.

Summary
Laureate Professor Smith received an AM for his research on human pregnancy and contributions to Indigenous maternal health. His research has dramatically expanded in the last 5 years to include stillbirth, viral infections during pregnancy, early detection of renal disease, the development of targeted nanoparticles for delivery of therapeutics to the uterus, and data-linkage to test the impact of antenatal care. His research seeks to optimise the health of pregnant women and their children.
This project will test if the ratio of the two different estrogens found in the blood of pregnant women is the critical factor in determining the onset of contractions in the uterus at labour. The studies will also determine the role of a newly discovered receptor for estrogens in allowing powerful contractions at labour. Results will allow development of new treatments to prevent premature birth that block the actions of estrogen at this new receptor or change the ratio of the two estrogens.
Achieving Targeted Delivery Of Drugs To Uterine Muscle In Women For The Prevention Of Preterm Labour

Summary
We have patented liposomes targeted to the uterus, which enable us to deliver drugs specifically to the muscle cells of the uterus, increasing safety. The liposomes can be loaded with drugs that either block or promote contractions, creating a versatile drug delivery system that could treat premature labour or postpartum haemorrhage which are major clinical problems. We seek support to demonstrate their effectiveness in mouse and primate models of preterm labour prior to human studies.
Living on the Margin: The Relationship between Mental Health and Work in Australia. This project will assess the relationship between Australians' mental health and their work, for example, employment status, work conditions and hours. The study is the first to exploit the detailed timing of mental health and employment transitions to identify whether poor labour market outcomes lead to poor mental health or whether the reverse is true. New Australian data will be used to understand whether the ....Living on the Margin: The Relationship between Mental Health and Work in Australia. This project will assess the relationship between Australians' mental health and their work, for example, employment status, work conditions and hours. The study is the first to exploit the detailed timing of mental health and employment transitions to identify whether poor labour market outcomes lead to poor mental health or whether the reverse is true. New Australian data will be used to understand whether the link between mental health and work adds to the economic vulnerability of families and those at risk of homelessness. The results will advance our understanding of the way that mental health affects overall economic well-being and will inform current policy initiatives to promote economic participation and good mental health.Read moreRead less
Human Capital, Cognitive Skills and Labour Market Outcomes. As Australia competes in the ‘educational race,’ this project will generate new knowledge on the relationship between education, skill attainment and economic outcomes in Australia. The research will provide new empirical evidence on cognitive and non-cognitive skills formation over the life-cycle, and the relationship between these skills and labour market outcomes in Australia within the broader international context. The research wil ....Human Capital, Cognitive Skills and Labour Market Outcomes. As Australia competes in the ‘educational race,’ this project will generate new knowledge on the relationship between education, skill attainment and economic outcomes in Australia. The research will provide new empirical evidence on cognitive and non-cognitive skills formation over the life-cycle, and the relationship between these skills and labour market outcomes in Australia within the broader international context. The research will advance methodological techniques for the economic analysis of cognitive skills and their economic impacts. The research will inform public policy formulation relating to educational attainment, skill development, and strategies to encourage longer workforce engagement over the life-cycle.Read moreRead less

Summary
Preterm birth is a major problem in our society, and has enormous consequences for parents and children. It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth. They have not been shown to reduce the rates of the serious neonatal problems associated with prematurity.

It also has a major impact on scarce financial resources. When women present in preterm labor, current therapies have only limited success in stopping contractions and postponing birth. They have not been shown to reduce the rates of the serious neonatal problems associated with prematurity. This project will be coordinated in Newcastle, N.S.W., and will involve major perinatal centres throughout Australia, along with overseas centres. It will test a new combination of drugs for their ability to postpone delivery in women presenting with preterm labour. It is postulated that the combination of drugs will be more effective than existing therapies. The drugs used in the trial are Nifedipine and Rofecoxib. Complications of prematurity include neonatal death, cerebral palsy, visual and hearing impairment, and chronic lung disease. These complications are most significant in extremely premature infants - in particular, those under 28 weeks gestation at the time of their delivery. For this reason, the study will focus only on women presenting in labour below 28 weeks. The ability to stop labour is important, but the main aim of any treatment for preterm labour is to reduce the rates of neonatal death and handicap. Babies born to women enrolled in this study will be followed for a period of one year after birth to assess their outcomes. It is our hypothesis that the combination of Rofecoxib and Nifedipine will result in lower rates of death and handicap in babies than Nifedipine alone. In addition, we will examine the rates of side effects in women receiving therapy. Currently used therapies, including intravenous ventolin, have high rates of maternal side effects. Nifedipine and Rofecoxib have both been shown to have low rates of maternal side effects.Read moreRead less

Under the Fair Work Act 2009 (Cth), lawful industrial action may be taken by employees in support of collective bargaining, provided that they have first authorised the action in a secret ballot. This research project explores the effect of the statutory process by which a bargaining representative of such employees seeks permission from the Fair Work Commission to conduct a ballot. It will examine the impact of the ballot requirement and statutory process on decision-making by bargaining representatives and subsequent employee access to industrial action in order to understand the effect of the regulatory scheme on enterprise bargaining behaviour. It is the first empirical study of strike ballots, analysing an important public policy area.Read moreRead less
