Detrusor hyperactivity with impaired contractility (DHIC) is a common clinical entity that is poorly understood, under-recognized, and difficult to effectively manage. It is a condition in which patients unexpectedly display detrusor overactivity (DO) during storage, yet are unable to mount a sufficient detrusor contraction during voiding to completely empty the bladder. It was first described by Resnick in 1987, as the second most common cause of urinary incontinence in institutionalized elderly people. Although initially described in frail institutionalized elderly, DHIC has been increasingly recognized as a cause of lower urinary tract symptoms (LUTS) in elderly patients . DHIC was identified as the principal dysfunction in up to 8-18% of elderly patients referred for urodynamic studies, furthermore DHIC was more commonly seen in men. There is no defined treatment algorithm for patients with DHIC, but typically, patients have been treated based on the severity of their particular symptoms. Sacral neuromodulation (SNM) is currently approved as a treatment for both idiopathic DO, and non-obstructive urinary retention independently. It is theorised that SNM would potentially treat both aspects of DHIC, the DO and poorly contractile bladder. Currently, there are no studies evaluating the efficacy of SNM for DHIC. In this study, we aim to evaluate the efficacy of SNM for treating DHIC.

The aim of this research is to test the impact of micronutrient enhance or micronutrient + milk lipid enhanced milk beverages on cognitive function in primary school aged children. The intervention products have been formulated on the basis of growing research suggesting a beneficial role of milk lipids for supporting brain health and, by extension, cognitive function. As part of this study, children aged between 7 and 9-years + 4-months at trial commencement will be randomly allocated to an active intervention arm (micronutrient enhanced OR micronutrient + milk lipid enhanced) or placebo arm (standard milk). Participants will consume two 150ml serves of the study product daily for 24 weeks. On the basis of previous research results on both micronutrient and milk lipids, the following hypotheses are made: 1) Consumption of two serves of micronutrient + milk lipid enhance beverages daily for six months will lead to improved cognitive function compared to micronutrient and control groups. 2) Consumption of two serves of micronutrient enhanced beverages daily for six months will lead to improved cognitive function compared to the control group.

The Signposts for Building Better Behaviour program is a manualised parenting intervention, initially developed to assist parents in managing difficult behaviour seen in children with an Intellectual Disability. More recently, research suggests efficacy when used with the parents of children with an Acquired Brain Injury, where challenging behaviours are a reasonably common and persisting long-term sequelae of the injury. The current study is investigating the feasibility, consumer satisfaction, and preliminary efficacy of delivering the program with online clinician support, via videoconferencing. We hope that delivery through this medium may improve program access for families, where barriers such as living in rural areas or working full time would have prevented them from participating in the face-to-face format that is usually offered through rehabilitation services. It is expected that the program will have a high level of parent satisfaction, when delivered with this mode of clinician support. It is also expected that relative to those who received treatment as usual, those who completed 'Signposts' will report: 1. Lower levels of child behaviour problems, both internalising and externalising 2. Lower levels of parental distress 3. Lower levels of dysfunctional parenting 4. Higher levels of family functioning 5. Higher levels of satisfaction in the parenting role. Further, it is predicted that these effects will be maintained post-intervention, with no significant increases in behaviour problems, parental distress or dysfunction, and no significant decreases in family functioning or parent role satisfaction, reported at 4-month post-intervention follow-up.

This research is aiming to test an intervention led by the practice nurse in general practice to calculate and discuss people's individual risk of bowel cancer and screening tests in order to have risk appropriate screening to detect a malignancy or pre-malignancy as early as possible. Who is it for? Any primary care patient aged between 50 and 74 years who has an appointment with a general practitioner (GP) who is participating in the study. Anyone who has had a previous colorectal cancer diagnosis will not be eligible. Study details: Participants in this study will be randomly (by chance) allocated to one of two groups. Participants in one group will continue to receive the usual care in the primary care clinic. Participants in the other group will go through a web-based colorectal cancer risk assessment with the research nurse, who will then provide risk output and screening advice which can be discussed with their GP. Our primary aim is to determine well the risk assessment tool encourages patients to have and doctors to recommend colorectal cancer screening that is appropriate for the patient’s actual risk of developing the disease. The research is part of a larger body of research: the 'NHMRC Centre for Research Excellence for Reducing the Burden of Colorectal Cancer by Optimising Screening: Evidence to Clinical Practice'.

Sporting injuries cost the Australian community approximately $1.65 billion annually and are the most common form of injury sustained by adolescent individuals. Severe sporting injuries can have serious health repercussions for young people and lead to the development of osteoarthritis and low back pain (LBP) later in life. Injury in the adolescent years may also discourage future sports participation and lead to physical inactivity, a major risk factor for the development of coronary heart disease, type 2 diabetes and various forms of cancer. Sporting injuries can also increase the risk of future sports-related injury, decrease individual/team performance and negatively impact psychology. In the sport of cricket, fast bowlers sustain the most injuries, some of which can be severe and result in a large loss of playing time. Various risk factors for injury have been identified in cricket pace bowlers however, limited research has attempted to examine if these risk factors can be modified. This study will therefore attempt to employ an exercise-based intervention to modify known risk factors for injury in cricket pace bowlers. Hypothesis: It is hypothesised that the exercised-based injury prevention program utilised in this study will successfully modify a range of risk factors for injury in adolescent pace bowlers. The control group may show pre/post-test changes however, these changes are expected to be significantly smaller to those seen in the intervention group

Ketamine is an induction agent to induce general anaesthesia in the emergency department, associated with less frequent episodes of hypotension than other agents such as thiopentone1 or propofol2. However, it is typically associated with increases in blood pressure in stable patients, and can cause hypotension in shocked patients3. In critically ill patients, avoiding hypotension is important, as it’s occurrence is known to be associated with poor outcomes4, particularly in the head injured patient5. However, hypertension is also associated with poorer outcomes, particularly in patients with intracranial bleeds (although cause and effect is not established) 6, and is usually avoided in haemorrhagic shock, due to consensus concern about increasing bleeding7,8. Co-administration of fentanyl during rapid sequence induction has been advocated as leading to less deviation from baseline haemodynamics9. It remains unclear whether in the emergency department and pre-hospital setting, this has any significant impact on mortality, and this exploratory study aims to evaluate whether patients undergoing RSI with ketamine and fentanyl, rather then ketamine and placebo have fewer episodes of adverse haemodynamic effects (systolic blood pressure less to 91 mmHg or greater than 149 mmHg) within the first 10 minutes following induction, and whether there is a subsequent difference in mortality at 3, 7 and 30 days. The study will be powered to detect a difference in the percentage of patients who meet the primary endpoint of low or high blood pressure, and will be used to inform future work regarding difference in mortality benefit. 1.

This pilot study will investigate the feasibility of implementing a multidisciplinary pre-operative very low calorie (VLCD) weight loss program in adult obese patients awaiting general elective surgery. This study will initially enrol a pilot sample of 50 patients who have a Body mass Index (BMI) equal to or over 30kg/m2 who attend the Pre-admission clinic for elective general surgery at The Prince Charles Hospital. Participants will be randomised into a control group or an intervention group. Participants in the intervention group will follow an 8 week very low calorie diet that incorporates Optifast meal replacement shakes. Participants randomised to the control group will receive standard care that includes a generic weight loss information pack provided by the clinic nurse. Measures to assess health related quality of life, body composition and adherence to the program will be collected. Unfavourable surgical outcomes will be measured until 30 days post elective surgery.

Major depression affects one in 16 young Australians. The first line of pharmacological treatment for severe depressive disorders in young people is selective serotonin reuptake inhibitors (SSRI). However, beneficial clinical effects are rarely observed before 4-8 weeks, whilst negative side effects (e.g., increased activity leading to increased suicide risk) are present. Consequently, a major question is whether there is a treatment strategy that could alleviate depressive symptoms in the initial 4-8 weeks? Recent data showed that a single dose of nitrous oxide (N2O) in adults with severe depression had significant antidepressant effects, and maximum effects were observed 24 hours after administration. However, no studies using N2O in minors have been conducted. The proposed research aims to investigate whether N2O has the same antidepressant effects in minors by using a between-group single-blind design. Participants will be randomly allocated to treatment (N2O) or placebo, and monitored weekly up to 12 weeks after treatment initiation. We expect that an average improvement in mood will be observed for the group allocated to the nitrous oxide condition.

The aim of this study is to determine if tailored, theory informed Knowledge Translation (KT) interventions can increase the uptake of an Australasian bronchiolitis guideline in reducing the use of therapies/management known to be of no benefit in the management of infants with bronchiolitis. This will be done by conducting a cluster randomised controlled trial - randomising hospitals to either intervention or control groups with focus on Emergency Department and General Paediatrics units. Results from this study will influence the implementation of other guidelines and evidence based practise in paediatric settings.

The overall aim of this research is to explore the effects of a program of sensory motor integration activities, The Learning Connections Schools Program, on young children’s behaviour, development and early academic skills. In order to achieve this aim, the objectives are to: *Conduct a cluster, pragmatic, unblinded, controlled trial to investigate the effect of a program of sensory motor integration activities on behaviour, development and academic skills in children in Prep Year and Year 1 of school. *Implement the sensory motor integration program with a group of children (the experiment / intervention group) in Prep Year and Year 1, across a variety of schools *Determine the effects of this program on behaviour, development and academic skills in that group of children by examining before and after measures *Compare the results from these children to the results for a control group of children in the same years of schooling, from similar schools, who have not participated in the sensory motor integration program. Sample All Brisbane Catholic Education primary schools have been invited to participate. Of those that volunteered, 12 will be randomly selected to participate using a computer-based random number generator selection process (randomisation). School Principals will then be required to consent to their school participating in the research. As well teachers will be asked to consent to participation in the research, and parents will be asked to consent for their children to undertake the sensory motor program in class and undertake the assessments as part of usual classroom activities. The final sample will consist of six (6) control schools (3 urban; 3 rural/semirural/regional) and six (6) experimental schools (3 urban; 3 rural/semirural/regional). Based on the average school with an intake PREP year of 50-60 pupils (with an average class size of n = 25-30), this will result in an expected sample size of between 600 to 720 pupils across 12 schools. Inclusion criteria *All Brisbane Catholic primary schools with PREP year and Year 1 classes. Exclusion criteria *Schools with existing sensory motor integration programs (for the control group)
