Summary
Pregnancy complications still causes the death of mothers, and their babies. During this fellowship, we will be developing new treatments and clinical tests for three important complications of pregnancy. We will run clinical trials of a new medication based treatment to cure ectopic pregnancies. We will also develop a blood test that can identify those babies still in the womb but suffering dangerously low oxygen levels.

Summary
Vitamin D deficiency affects about 1 billion people worldwide, including up to 80% of Australians depending on age, skin colour and sun exposure. Vitamin D deficiency has now been associated with a large number of common diseases of aging and with pregnancy complications. This proposal will use human pregnancy serum and placenta, as well as mouse gene knockout models, to determine the hitherto unknown roles of vitamin D in development of the placenta and health of mother and baby.
Stillbirth is a global public health problem affecting 3 million babies annually. In Australia, almost 3,000 stillbirths occur each year, many of which are preventable if the pregnancy is recognised as being at risk. This fellowship will develop novel non-invasive techniques to identify these at risk pregnancies using biomarkers in the mother's blood and cutting edge imaging. The efficacy of these novel techniques to prevent stillbirths and improve pregnancy outcomes will then be assessed.
The Pathogenic Role Of A Placenta-specific Protease In Early-onset Preeclampsia

Summary
Preeclampsia (PE) is a life-threatening disorder of pregnancy. If left untreated, PE will lead to maternal as well as fetal death. Unfortunately, the only current effective “cure” for PE is to deliver the baby prematurely. The causes of PE are intrinsically related to the placenta, the organ that connects the fetus to the mother. This project will investigate a unique enzyme that is produced only by the placenta, its contribution to PE and its potential as a target for PE treatment.
Predicting Intrapartum Fetal Compromise At Term Using The Fetal Cerebro-umbilical Ratio And Placental Growth Factor Levels

Summary
A lack of oxygen to a baby after the onset of labour (i.e. fetal distress) in an otherwise healthy pregnancy is one of the top three causes of death in singleton pregnancies after 37 weeks. Our previous research has shown that a late pregnancy ultrasound scan combined with a blood test from the mother measuring the levels of a placental hormone can potentially identify pregnancies at risk. We aim to assess the value of this screening test at a major tertiary hospital.
Development Of Novel Medical Therapies To Cure Ectopic Pregnancies

Summary
Ectopic pregnancies are conceptions implanting outside the womb, mainly the fallopian tube. They are pathological, and can erode straight through the tube into large blood vessels causing fatal bleeding and death. We plan to assess three medication based approaches to treat this condition that would avoid surgery entirely. If we succeed, and subsequently translate one or more of these treatments to the clinic, it would revolutionise management of this serious gynaecological emergency.

Summary
Infertility affects 1 in 10 couples. In early pregancy miscarriage is the commonest complication resulting in the loss of 10-15% of all conceptions. During the latter part of pregnancy, complications such fetal growth restriction and preeclampsia, affects up to 10% of women resulting in considerable suffering to the mother and her newborn. Many of these births are premature with neonates requiring intensive care. There is also good evidence that children who are born prematurely with low birth w ....Infertility affects 1 in 10 couples. In early pregancy miscarriage is the commonest complication resulting in the loss of 10-15% of all conceptions. During the latter part of pregnancy, complications such fetal growth restriction and preeclampsia, affects up to 10% of women resulting in considerable suffering to the mother and her newborn. Many of these births are premature with neonates requiring intensive care. There is also good evidence that children who are born prematurely with low birth weight are much more likely to develop a host of diseases including cardiovascular disease, diabetes and obestiy in adult life increasing the long term burden of health care support. Infertility is often due to the lack of uterine endometrial receptivity while the pregnancy complications arise from the reduced growth of the placenta and sub-optimal interactions between the mother's uterus and the growing placenta. Endometrial infertility, placental growth and interactions with the endometrium is stringently regulated by substances produced at the maternal endometrial- placental interface. To understand how infertility and pregnancy complications arise, develop diagnostic, monitoring and therapeutic tests it is critical to understand the roles played by these regulatory substances. We have novel data suggesting that small proteins known as endogenous opioids could be enchancing endometrial receptivity and the growth and development of the placenta. Interstingly these substances are closely related to exogenous opioids such as heroin and morphine. We will investigate the manner in which these substances regulate endometrial immune cell function, maintain the endometrial stromal cell bed in preparation for pregnancy and direct the growth and differentiation of the placenta. The findings will give novel insights into infertility, improve the success rates of in vitro fertilization, reduce maternal and neonatal complications of pregnancy.Read moreRead less
Measuring Hypoxia Induced MRNA In Maternal Blood To Monitor Wellbeing Of Growth-restricted Fetuses

Summary
Severely growth restricted fetuses are at peril of stillbirth from low oxygenation. While ultrasound monitoring improves outcomes, babies are still lost. Better ways to monitor the health the unborn baby are needed. We have recently discovered fetuses’ starved of oxygen leak RNA into mother's blood. Thus, measuring RNA molecules in blood could be used to assess fetal health. We will examine whether measuring mRNA in maternal blood could be used to monitor wellbeing of growth-restricted fetuses.

Summary
If a baby does not grow properly during pregnancy there can be serious health problems when it is born. We also know that small babies have life long risks of poorer health. We have no effective therapies for improving a baby's growth. This application aims to discover a treatment that can help babies grow. This would be an important advance in improving the health of our future Australians.
The Cardiovascular Toll Of Pre-eclampsia: Determining Impacts On The Maternal, Fetal And Placental Vasculature.

Summary
Pre-eclampsia is a common condition of pregnancy that causes a rise in blood pressure, protein in the urine and damage to other organs. It can cause significant harm to the mother and baby. In the long term, mums who have had pre-eclampsia are at a higher risk of developing heart problems. We want to explore how the heart changes in a pregnancy complicated by pre-eclampsia, and see if these changes can help us predict pregnancy risk and long term outcomes.
