Consumption of foods rich in saturated fats have been associated with elevated blood lipid levels and adverse health effects. However studies using animal models have demonstrated that dietary saturated fats raise blood lipid (cholesterol and triglyceride) levels only when the diet is deficient in n-3 PUFA. If the same is true for humans, this research will have important implications for the prevention of cardiovascular and other chronic diseases. Therefore we hypothesise that saturated fat consumption does not raise blood lipid levels if the diet is sufficient in omega-3 polyunsaturated fatty acids. We also hypothesise that the benefits of n-3 PUFA can be optimised when consumed in combination with saturated fats. This is a randomised controlled, dietary intervention trial, in parallel design with healthy adults. Blood samples will be collected at baseline and after 6 weeks of dietary intervention with omega-3 polyunsaturated fatty acids (n-3 PUFA) supplementation either in combination with saturated fat or omega-6 Polyunsaturated fatty acids (n-6 PUFA). The saturated fat group will consume butter (24g, which can be spread on bread, muffins or crackers), white chocolate (40g) and 4 capsules of fish oil (4 x 0.5g), participants will also be advised on how to use more foods containing saturated fat for cooking. The n-6 PUFA group will consume margarine (20g, which can be spread on bread, muffins or crackers), sunflower seeds (42g) and 4 capsules of fish oil (4 x 0.5g), participants will also be advised on how to use more foods and oils containing n-6PUFA for cooking. Participants will be asked to fill a medical and a physical activity questionnaire and will have their anthropometric measurements taken in each of their visits. Subjects will also complete a 3 day food record.

This cohort study aims to investigate the in-hospital mortality of patients with a displaced femoral neck fracture when treated with a cemented femoral component. This un-selected series will be the largest in the current literature. There is some discussion in the orthopaedic community about the role of cement in post-operative mortality. The aim of this study is to examine this more closely in a controlled setting where every patient requiring arthroplasty receives the same cemented prosthesis as standard care.

This project is part of a research program funded by beyondblue to develop and evaluate Internet based treatment programs for older adults (60+) with anxiety and depression. This project examines the relative efficacy of guided and self-guided internet delivered treatment. Additionally, the study aims to examine the effect of a pre-treatment interview upon treatment outcomes for self-guided interventions. We expect that the guided intervention will result in superior outcomes to the self-guided interventions. Additionally, we expect that the self-guided intervention which includes a pre-treatment interview will result in superior outcomes when compared to the self-guided intervention without the interview.

Polyvinylpyrrolidone (PVP) has been routinely used in the intracytoplasmic sperm injection procedures to facilitate sperm handling for years although it's not degradable by the egg. Hyaluronan is a new alternative to PVP with all the features that PVP has and it's degradable by the egg. The proposed study aims at comparing the embryonic effect between these 2 reagents by using time-lapse analysis.

PICSI dish and Spermslow (liquid hyaluronan) are both hyaluronan binding-based sperm selection methods. Publications have shown benefits of sperm selection by either method before intracytoplasmic sperm injection. However few study has compared the efficacy between these two methods. The proposed study will compare sibling embryos resulted from these two methods by using time-lapse analysis.

Both Swim-up and Density gradient centrifugation are routine sperm preparation methods in IVF laboratory. However the content of seminal fluid might mix with separated sperm in the Swim-up method while centrifugation is involved in the other method which are both considered harmful to fertilisation and embryo development. The proposed study will use time-lapse technology to reveal the differeces in the subsequent embryo development.

Placebo-controlled, First-In-Human study assessing the safety and tolerability of PRN473 in healthy volunteers. Partipants in Part A of the study will recive a single dose of PRN473. Partipants in Part B of the study will recieve one dose of PRN473 per day for up to 14 days.

The purpose of the study is to investigate the effect of a physiotherapy intervention program with able-bodied 4 year old children born extremely preterm or with extremely low birth weight on their motor co-ordination, postural stability and functional performance compared to no intervention. Also the study will examine the impact of the intervention on behaviour. OBJECTIVES 1. To evaluate the movement benefits of a specifically developed 6 week small group physiotherapy intervention program for children aged 4-4.5 years. 2. To compare the motor development of children with and without intervention. 3. To evaluate the impact of intervention compared to no intervention on general abilities, activity levels and behaviour 12 months post baseline assessment. HYPOTHESES It is hypothesised that a physiotherapy intervention program will improve motor co-ordination, postural stability and functional performance in 4 year old children born extremely preterm or with extremely low birth weight. It is hypothesised that improvements in motor abilities amongst this group of children will have a positive effect on activity levels and behaviour compared to children who receive no intervention. Furthermore, it is hypothesised that there is a close link between motor performance and the ability to cope with social interactions and that early improvement will continue to impact on the child's motor development, attention and behaviour, not just in the short term but will have long term effects.

The aim of this study is to evaluate, in a randomised controlled trial, the feasibility, acceptability and efficacy of a text message-delivered intervention to enhance physical activity, dietary change and weight loss among adults who have completed the 6-month Get Healthy Coaching Service. It is expected that this extended contact via text messaging will lead to sustained behaviour change and weight loss compared to no on-going contact.

The transition to parenthood is a very exciting time for new parents, but it also is a time of great demands and challenges. After the baby is born, parents are faced with sleep deprivation, mastering infant caregiving tasks, changes in their relationships and lifestyle. At the same time, these early months are crucial for the infant's development and wellbeing. The proposed project aims to evaluate Baby Triple P, a preventative intervention designed to support parents during the transition to first­time parenthood. It aims to give babies a healthy start in life by enhancing their parent’s knowledge, skills and confidence in early parenting practices. In addition, it intends to protect the mental and emotional wellbeing of parents. The transition to parenthood can be particularly challenging for families where a range of risk factors are present, and it is couples who are at risk for experiencing difficulties at the transition that may benefit most from a preventative intervention. Specifically, this project focuses on couples who experience at least two of the following risk factors: unplanned pregnancy, low education, experience financial strain, low relationship satisfaction, low social support, history of and/or current depression or anxiety, low confidence in ability to parent or low life satisfaction. This was done as these couples may benefit the most from Baby Triple P. Participants will be approximately 150 couples where the mother is 20­-35 weeks pregnant. Recruitment will be done through primary care settings, GPs, hospitals in the Brisbane and Ipswich area and targeted mail­out and media campaigns. The research will be carried out as a randomised controlled trial comparing the Baby Triple P group to a care as usual group. The study is a 2 (Baby Triple P vs care as usual) x 3 (time­points: pre­test, post­test, 6­month follow up) design. The intervention consists of four weekly 2­hour group sessions during pregnancy, and four weekly 20­ minute telephone consultations starting when the baby is about 6 weeks old. Assessment will include a series of self­report questionnaires (pre­, post­, and follow­up) and a home observation, which will observe mothers as they normally interact with the baby (post­ and follow­up). The primary outcome variable for this study is parental confidence/ self-efficacy. Accordingly, it is hypothesised that compared to the care as usual group: H1: Participation in Baby Triple P will lead higher levels of parenting confidence and perceived competence. This study will also look at several secondary outcome variables. For these,it is hypothesised that, compared with the care as usual control group, participation in Baby Triple P will lead to: H2: higher levels of parental responsiveness and bonding to the baby., H3: higher relationship happiness, H4: higher levels of life satisfaction H5: fewer instances of depression or anxiety H6: Infants will show less fussing, crying and fewer sleeping p
