The reduction in quality of life and illness burden experienced by people with end stage kidney disease (ESKD) is exacerbated by the condition of ‘uraemic neuropathy’. Uraemic neuropathy affects between 60 and 100% of people with ESKD and can lead to loss of function as well as discomfort or pain. It is progressive with no specific cures or methods of retarding progression other than transplantation. The FINESSE study will compare the effect of haemodiafiltration and standard haemodialysis with high-flux membranes on the development and progression of uraemic neuropathy.

This study investigates possible effects of epidural pethidine and norpethidine on the initiation and establishment of lactation and brestfeeding behaviour of the infant.

The ENVIS-ion trial will examine whether low dose aspirin is effective in delaying the onset of declining abilities of thinking and memory in healthy older adults. Participants in the ENVIS-ion trial will be recruited from men and women who have agreed and consented to participate in the clinical trial of low dose aspirin (the ASPREE Trial ISRCTN83772183). The main features of the ENVIS-ion trial are additional measurement of brain and retinal structures by magnetic resonance imaging (MRI) and retinal photography in each participant before starting on the study drug and after treatment with aspirin or placebo for 3 years. As a part of the ASPREE study, mental functions are assessed every year by questionnaires administered by a trained researcher. For ENVIS-ion, participants will have extra questionnaires to further test their mental abilities. MRI of brain structure will detect markers of early worsening of thinking and memory abilities. Blood vessels of the retina share many features with vessels of the brain. We will compare whether aspirin lessens changes over time of features shown with brain MRI and retinal photography and compare these with the questionnaire measurements of mental function.

The purpose of this study is to see if hands-on demonstration of child restraints, seat distribution and explanation of the right child restraint for a pre-school child can increase the use of appropriate child restraints in children aged 3-5 years. This program will be given to parents and guardians in their child’s pre-school. We will determine whether it works by comparing 14 pre-schools who get the program to 14 pre-schools who do not at the end of the school year. The number of children correctly using appropriate child restraints will be compared between the two arms of the study. It is known that a large proportion of pre-school aged children are not in appropriate child restraints, and/or are not restrained correctly, increasing their risk of injury in road crashes. We will develop and evaluate an educational intervention to increase correct and appropriate child restraint use in 3-5 year olds. The study design is a cluster randomised controlled trial and this type of design is considered a gold standard for evaluating the effectiveness of an intervention. Each of 28 pre-schools involved in the study will be randomly allocated to either receive the intervention or to continue with usual road safety programming. This randomised trial will be one of a small number of similar studies conducted internationally and the findings of this study will contribute important evidence for policy makers and road safety educators.

This study will try to identify and prioritise causes of poor intake in a representative older medical inpatient population. Approximately three hundred consecutive patients aged 65 years and over admitted to the general medical units at Royal Brisbane and Women’s Hospital will be studied. Information on potential causes of poor intake (identified from the literature and through expert clinical consultation) including poor appetite, swallowing difficulties, delirium, depression, dietary limitations, and need for feeding assistance will be collected on day 3 and 7 of the hospital stay. On each of these days, dietary intake will be determined. Standard statistical modelling techniques will be used to identify which factors predict poor (<60% recommended) intake, after adjusting for important confounders such as age, sex and burden of illness. These results will be supplemented by detailed interviews with a smaller selection of patients and their carers in order to ensure the patients experience is adequately represented in the research.

The aim of this project is provide the NSW Department of Education and Training (DET) and other current or potential users of low NOx emission heaters with independent, reliable and unbiased evidence of their short-term impact on exposure to pollutants, symptoms and function in primary school-age children.

Background: Oxidative stress and inflammation are associated with increased cardiovascular morbidity and mortality particularly in patients with end stage kidney disease. Observational data support the contention that increased antioxidant intake with nutrients such as vitamin E is correlated with reduced cardiovascular morbidity and mortality in the general population. Unfortunately, most clinical intervention trials using vitamin E have failed to support this relationship. The SPACE study conducted in hemodialysis patients had a positive outcome however this has not been translated into clinical practice perhaps because of the negativity generated from studies in the general population. The failure of studies using vitamin E other than the SPACE study may simply be as a consequence of choosing the wrong form of Vitamin E, prescribed at the wrong dose, for the wrong duration to the wrong patients. Future research in this area should focus on treating patients with established measured abnormalities of oxidative stress, with a safe vitamin E formulation that is proven to be effective, at least in part, in reversing the observed oxidative stress abnormalities. Methods: Therefore, the aim of this study is to investigate the effect of different doses of vitamin E supplementation on oxidative stress markers in hemodialysis patients with proven abnormalities of oxidative stress. The study will consist of a time-course study and a dose-ranging study. In the time course study eight patients will be required to take 1600 IU/day natural (RRR) alpha tocopherol for 20 weeks. Blood will be collected every two weeks and analysed for a marker of oxidative stress (plasma isoprostanes) and alpha tocopherol. The optimum time period to decrease oxidative stress (by 50%) will be determined from this study. It is hypothesised that this will occur within 16 weeks. In the dose-ranging study 48 patients will be randomised to either placebo, 100IU/day, 200IU/day, 400IU/day, 800IU/day or 1600IU/day of natural (RRR) alpha tocopherol for a time period determined from the time course study. Blood will be collected at baseline and at the end of the study and analysed for a plasma isoprostanes and alpha tocopherol. It is hypothesised that doses =800 IU of vitamin E will be required to decrease oxidative stress by 50%.

This study aimed to investigate whether an educational intervention could improve the bra knowledge and bra-wearing behaviour of active adolescent females. It was hypothesised that, compared to a control group who did not receive an intervention, the experimental group would significantly improve their: (i) knowledge of bra fit and bra design, and (ii) ability to select a supportive, correctly fitted bra appropriate to their level of sport and breast size.

The aims of the project are: -to evaluate Acceptance and Commitment Therapy (ACT) as a form of therapy in treating psychotic symptoms in an Acute Inpatient Service -to develop and administer a four-session intervention of ACT to treat psychotic symptoms in an Acute Inpatient Service -to evaluate the long-term effects of an ACT intervention in an Acute Inpatient Service -to replicate the findings of previous research in an Australian population The aims of the ACT treatment are: -to reduce rehospitalization rates for people with psychotic disorders -to reduce believability of positive symptoms -to increase commitment to value-based behavioural goals by people with psychotic illnesses

This trial is the pilot randomised controlled trial to trial ACTRN12608000252314. The pilot randomised controlled trial (RCT) will test a novel telephone-based supportive care intervention for people with colorectal cancer. The intervention involves five structured calls from a nurse to the patients over the 6 month period after discharge from surgery. The intervention aims to improve psychosocial outcomes for patients. This pilot study aims to assess the feasibilty and acceptability of the intervention and determine any impact on patient outcomes. If the results are positive, this telephone intervention will be evaluated in a multi-centre randomised controlled trial (RCT) and could be implemented broadly in both metropolitan and rural areas, and could be adapted for other groups of carers.
