Summary
While it is known that depression, anxiety and stress in pregnancy increase the risk for poorer child mental health, what is unknown is the key pathways and intervention points to prevent this transmission of risk. This study will examine potential mechanisms and intervention points through a selected cohort study: Mercy Pregnancy and Emotional Wellbeing Study. This study follows 500 women and their children from first trimester in pregnancy until the children are 3 years of age.

Summary
We know that our health as adults is influenced by the lifestyle of our mothers during pregnancy. In particular, increased risk of adult-onset diseases such as diabetes and cardiovascular disease occurs when small and lean infants at birth are raised in conditions where nutrient intake is not restricted and obesity occurs. This concept of fetal programming is now widely accepted. Our laboratory is leading research in a new concept, that of embryonic programming.

In particular, increased risk of adult-onset diseases such as diabetes and cardiovascular disease occurs when small and lean infants at birth are raised in conditions where nutrient intake is not restricted and obesity occurs. This concept of fetal programming is now widely accepted. Our laboratory is leading research in a new concept, that of embryonic programming. We have extensive animal data demonstrating that exposure of embryos to physiological perturbations alters fetal development, similarly to that occurring in nutrient restriction during pregnancy. Furthermore, there is data from IVF-derived children that their birth-weight is lower than expected, possibly due to the conditions used for conception in the laboratory. How does the response by eggs and embryos, at the time of conception, affect subsequent development? There has been some focus on changes to DNA that are not related to mutations, but structural changes in the DNA that alters gene expression. We call this epigenetics and epigenetic changes are found in embryos, including human embryos following IVF. However, no one knows how such epigenetic changes occur as a result of this stress response by the egg or embryo. Our proposal is to determine the mechanism of how epigenetic alterations take place in eggs and embryos. Our theory is that the mitochondria, the energy producing packages within all cells, are sending signals to the embryo's nucleus. When the egg or embryo finds itself in adverse conditions, the signals change as a result of changes in the energy balance. This in turn changes the activity of enzymes in the nucleus that regulates DNA structure. If we can prove that this relationship occurs, then we can assess these changes in human embryos that are excess to a patient's requirements and learn if programming takes place in human embryos.Read moreRead less
Evaluation Of Novel Antenatal Biomarkers For The Detection Of Adverse Pregnancy Outcomes: A Record Linkage Study

Funding Amount
$580,997.00
Summary
Although most pregnancies are associated with the birth of a healthy baby to a healthy mother, adverse pregnancy outcomes such as fetal growth restriction, stillbirth and preeclampsia continue to impose a heavy burden on families and the community. We will use a novel application of health record linkage to investigate maternal serum biomarkers for predicting adverse pregnancy outcomes. Intervention studies and preventative strategies will be developed for highly predictive biomarkers.
Treatment Of Bacterial Vaginosis: A Randomised Controlled Trial

Summary
The objective of this research project is to determine if the treatment of Bacterial Vaginosis (BV) can be improved. Bacterial vaginosis is one of the most common causes of vaginal discharge in women. It can also have serious consequences, such as premature labour and can also increase the risk of HIV transmission. These complication cost communities many millions of dollars; for example in the US it is estimated that premature labour caused by BV alone costs about 1 billion dollars a year. The ....The objective of this research project is to determine if the treatment of Bacterial Vaginosis (BV) can be improved. Bacterial vaginosis is one of the most common causes of vaginal discharge in women. It can also have serious consequences, such as premature labour and can also increase the risk of HIV transmission. These complication cost communities many millions of dollars; for example in the US it is estimated that premature labour caused by BV alone costs about 1 billion dollars a year. The currently recommended treatment for BV works well initially (first month about 80% respond) but by 12 months most (60%) have relapsed. This randomised clinical study is investigating new ways to treat BV. The currently recommended arm of treatment (antibiotic metronidazole) is being compared to two other treatments. The second arm of the study involves the use of two antibiotics at once (metronidazole and clindamycin) and the third arm involves the use of a bacterial (lactobacilli) and oestrogen. Lactobacilli are bacteria that may help maintain the normal bacterial (and there by prevent relapse of BV) and oestrogen may have a similar effect. If either of these treatments improved the longer term treatment of BV, very significant benefits would flow to affected women and the community as a whole.Read moreRead less
The Role Of The Intrauterine (pro) Renin-(pro)renin Receptor System In Prostaglandin Synthesis In Pregnancy.

Summary
Preterm birth is associated with a very high incidence of infant disability and mortality. This has long term economic and social costs to the Australian people. We will demonstrate that in late gestation, the intrauterine (pro)renin renin receptor system controls prostaglandin synthesis by the fetal membranes and the placenta. Prostaglandins can cause premature labour.
Impact Of Parental Alcohol, Tobacco And Other Substance Use On Infant Development And Family Functioning

Summary
The current study will be the first large-scale Australian birth cohort study to comprehensively examine the effects of substance use in pregnant women and their partners during the prenatal period on infant developement and family functioning. Dramatically improved knowledge of these effects will provide evidence-based direction to the development of public health policy and community interventions that aim to improve the health and wellbeing of Australian children and families.
Translating New Therapeutics And Diagnostics For Major Pregnancy Complications

Summary
My research is focussed on tackling major complications of pregnancy that are a threat to the lives of both mother’s and babies. We are developing new drug treatments for ectopic pregnancy (a dangerous condition where the pregnancy implants in the Fallopian tube), and preeclampsia (a condition where toxins leak out of the placenta into mum's blood, and can seriously injure many of mum's major organs). We are also generating a blood test that may help women avoid the tragedy of a stillbirth.
