Summary
Women in malaria-endemic areas such as coastal PNG are at high risk of malaria in pregnancy. To prevent the substantially increased malaria-associated morbidity and mortality in mother and child, and because even asymptomatic infections can be deleterious, there has been a move to giving antimalarial drugs regularly during pregnancy regardless of the mother's clinical or parasitological status.

To prevent the substantially increased malaria-associated morbidity and mortality in mother and child, and because even asymptomatic infections can be deleterious, there has been a move to giving antimalarial drugs regularly during pregnancy regardless of the mother's clinical or parasitological status. In poor tropical countries, such treatment usually comprises safe and inexpensive agents such as chloroquine and Fansidar. There are two main issues with this approach. First, the efficacy of such conventional agents is waning and this increases the risk of break-through malaria. Second, there are few data on how the drugs are handled in pregnancy on which to base recommendations for treatment. We plan to collect information on the disposition and effectiveness of chloroquine and Fansidar in women with malaria in pregnancy in PNG that should allow a critical appraisal of the usefulness of current regimens in PNG and in other tropical countries where parasite resistance to these agents is emerging. Artemisinin combination therapy (ACT) in the form of a novel artemisinin drug and a longer-acting partner has been suggested as the most promising alternative therapy for malaria in pregnancy if conventional drugs fail. We plan to assess the safety of a leading ACT formulation, namely dihydroartemisinin and the chloroquine-like drug piperaquine (DHA-PQ), in animals before extending our studies to women with malaria in PNG. These latter studies will allow an evaluation of the safety and efficacy of DHA-PQ as novel therapy for malaria in pregnancy in PNG and other tropical countries.Read moreRead less
Smoking Cessation For Youth Project Booster And Cohort Tracking Study

Summary
Adolescence is a critical period for the establishment of adult drug use behaviours. If smoking does not commence in teenage years it is unlikely to occur. This innovative project not only continues to address tobacco control with this important age group but also builds on evidence from a randomised intervention trial involving over 4,000 Year 9 students tracked over two years. This project was called the Smoking Cessation for Youth Project (SCYP). Preliminary longitudinal analyses of the SCYP ....Adolescence is a critical period for the establishment of adult drug use behaviours. If smoking does not commence in teenage years it is unlikely to occur. This innovative project not only continues to address tobacco control with this important age group but also builds on evidence from a randomised intervention trial involving over 4,000 Year 9 students tracked over two years. This project was called the Smoking Cessation for Youth Project (SCYP). Preliminary longitudinal analyses of the SCYP data indicate that the intervention students were significantly less likely to smoke heavily (smoking five or more days per week) than the control group and that intervention students were also significantly less likely to have tried smoking than the control group. These results represent a world first in evidence that population-based smoking cessation interventions among teenagers can be successful. The proposed project will determine the extent to which these positive intervention effects are sustainable, two years post intervention, as our cohort moves into Year 12. In addition to tracking the possible decay of SCYP intervention effects, the proposed project will also measure the effects of a booster intervention delivered students when they are in Year 12 (2002). The Year 12 intervention will comprise an innovative self-help 'magazine style' booster and a supportive environmental intervention involving school nurses and local GPs. This proposal represents a cost-effective opportunity to measure the effectiveness of a Year 12 tobacco cessation booster intervention. Further data on tobacco smoking behaviour in 2002 will also enable us to determine how long the SCYP intervention appears to affect behaviour and whether 'boosters' are needed in later secondary school years to maintain the benefits.Read moreRead less
A Randomised Controlled Trial Of Alternative Treatments To Intramuscular Penicillin For Impetigo In Aboriginal Children

Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.
A Behavioural Intervention For The Adoption & Maintenance Of Physical Activity In Type 2 Diabetes

Summary
For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on ....For people with type 2 diabetes (T2DM) it is essential that blood glucose levels are managed well to reduce the risk of developing complications. Physical activity is essential for maintaining glucose levels because it helps make the muscles use glucose more effectively. In particular, being active through strength training not only improves blood glucose levels, but can be very effective for maintaining good physical functioning, which is known to be reduced by having T2DM. This study builds on our earlier research which demonstrated significantly improved blood glucose levels from a strength training program for older adults with T2DM. The strength training program is to be administered nationally in a research to practice trial (Lift for Life); however, the original research found that those who did not complete the program as it was intended (ie, poor adherence) did not show significant improvements in blood glucose levels. Furthermore, maintenance of strength training exercises after completion of the program was poor and resulted in return of blood glucose levels back to pre-starting levels. In people without diabetes, we have collected pilot data that shows that the use of behavioural strategies based on behavioural theories whereby each person's motivations and barriers are taken into consideration is more effective than the traditional one-treatment-fits-all approach. This study will evaluate the effectiveness of using behavioural strategies for improving adherence and maintenance to the Lift for Life strength training program (Enhanced L4L) for older adults with T2DM compared with the Standard L4L program. It will also follow-up participants 6 months later to determine the extent to which the changes in behaviour can be maintained. The study will provide information that will assist in the design, delivery and uptake of programs to improve treatment strategies in older adults with T2DM through the maintenance of healthier behaviours and lifestyles.Read moreRead less
Mechanisms Underlying Growth, Lineage Commitment And Differentiation Of Liver Progenitor Cells

Summary
Liver disease is a serious health problem. Viral hepatitis, obesity and alcohol can result in end-stage liver disease. Organ transplant is the only treatment available. A widening gap between organ donations and recipients mandates alternative treatments are developed. Cell transplantation and artificial liver devices are alternatives which can use liver progenitor cells. We will investigate how factors grow and convert them into liver cells for treating liver disease patients.
