Establishing Antenatal Screening Uptake For Fetal Anomalies In The NT And Exploring Indigenous Womens Understanding

Funding Amount
$9,875.00
Summary
This project aims to investigate the views of Indigenous women, their families and health service providers about antenatal screening tests for abnormalities like Down syndrome. This will contribute knowledge about why there is low uptake of screening amongst Indigenous women, and whether changes in the provision of antenatal care are required. This is important because all women, regardless of their culture or location, should be offered the same opportunities and care during pregnancy.

Summary
Preterm birth with the resulting immaturity of babies is the leading cause of death and disease among newborns. Early birth occurs in 6 to 11% of pregnancies, and its rate is slowly increasing in industrialized countries. We need a much better knowledge of the regulation of the parturition process to find ways to reverse this trend. Prostaglandins are hormonal substances that stimulate uterine contractions, cervical dilatation and membrane rupture.

Early birth occurs in 6 to 11% of pregnancies, and its rate is slowly increasing in industrialized countries. We need a much better knowledge of the regulation of the parturition process to find ways to reverse this trend. Prostaglandins are hormonal substances that stimulate uterine contractions, cervical dilatation and membrane rupture. Intrauterine tissues produce prostaglandins, and an increase of prostaglandin levels in the uterus is likely responsible for inducing labour both normally and preterm. We have previously identified an enzyme protein in the fetal membranes, called prostaglandin synthase-2, that has a key role in the synthesis of intrauterine prostaglandins during pregnancy. This enzyme is increasingly expressed before labour onset. In the present application, we propose studies to determine what causes the increased expression. We hypothesize that the gene encoding this enzyme is specifically activated in the fetal membranes in preparation for labour. We will define the mechanism of regulation by determining the activity of the gene in tissues from women who deliver either spontaneously or without labour at term and preterm. Further, we will determine the interaction of regulatory proteins with the prostaglandin synthase-2 gene in these pregnancies in order to understand the mechanisms of regulation at the molecular level. Finally, we will conduct cell culture studies to experimentally manipulate prostaglandin synthase-2 gene activity in fetal membrane cells. As an overall outcome of this work, new targets may be identified for drugs to disrupt prostaglandin synthase-2 gene activation specifically in the fetal membranes. The long term perspective is to block prostaglandin synthesis in the uterus in order to suppress preterm labour and prevent preterm birth.Read moreRead less

Summary
In Victoria alone around 500000 Pap smears a year are examined for evidence of cancer of the cervix or conditions that may lead to cancer. This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used.

This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used. An alternative technique based on using infrared light to probe smears shows promise in providing such an easily automated reliable method. We, and others have spent a number of years exploring this technique and have solved a number of the problems associated with it. Based on our work in the field and the work of others we now wish to develop a methodology using an infrared micro-imaging spectrometer combined with multivariate statistics that can be used to diagnose cervical cancer and the conditions that lead to cervical cancer.Read moreRead less
