The effectiveness of early functional occupation-based therapy in a medical / surgical intensive care unit.
Expand descriptionAdmissions to intensive care units (ICUs) are increasing due to an aging population. With advances in medical care, patients are surviving an initial stay in critical care; however they are presenting with ongoing health and mental ability limitations following their stay in intensive care. Recent research has focused on the introduction of early rehabilitation within the ICU in an attempt to reduce the long-term complications regarding physical recovery and cognition. To date the exact scope and type of therapeutic care that occupational therapists can provide, as part of the multidisciplinary team, requires further investigation. This research project will investigate how useful and effective certain occupational therapy interventions can be in influencing longer term outcomes relating to physical strength and ability to complete simple daily activities such as self-care and grooming, following an early rehabilitation program within an intensive care unit. It will also interview patients who participated in the early rehabilitation program to understand how they felt about participating and whether there are changes that can be made to make their experience more beneficial. The results of this study will help to redefine how we provide occupational therapy in the intensive care unit and may help to support a clearer and more active role for occupational therapists in future critical care settings.

Relook Laparoscopy for Peritoneal Surface Disease (ReLaPSeD) Trial A prospective randomised controlled trial comparing relook laparoscopy vs. standard follow-up for early detection and treatment of patients at high risk for peritoneal metastases after resection of colorectal cancer
Expand descriptionThis study has been designed to compare relook laparoscopy versus standard follow up for early detection and treatment of patients at high risk for metastases after resection of colorectal cancer. Who is it for? You may be eligible for this study if you are aged between 18 and 80 years, have been diagnosed with primary colorectal cancer for which you have undergone colorectal resection, and are at high risk of the cancer spreading within the abdomen (peritoneal metastases). Study details Participants will be randomly allocated (by chance) to undergo either a relook laparoscopy 9-12 months after initial colorectal cancer surgery in addition to standard follow-up or continue with standard follow-up only. Diagnostic laparoscopy refers to examination of the abdominal cavity through minimally-invasive ("key-hole") surgery. Standard follow up tests include regular blood tests for levels of tumour markers (every three months) and regular CT scans (yearly). Participants will then be followed up over three years to assess disease status (i.e. remission or relapse) and to complete a series of questionnaires to determine quality of life. It is hoped that this research will help determine whether a relook laparoscopy is a valid and effective way of increasing survival rates in patients with high risk colorectal cancer.

Cognitive Improvement through early Restoration of cirCADian rhythms in very preterm Infants via Environmental Modification: The CIRCA DIEM Study
Expand descriptionCircadian rhythms are vital to normal fetal development but the fetus is dependent on maternal circadian rhythms until near-term. Preterm infants spend the first months of postnatal life in the disruptive setting of constant environmental light and noise, without maternal circadian inputs. In animals, disturbed circadian rhythms are associated with impaired brain development. Cognitive impairment remains the primary morbidity associated with extremely preterm birth and increases health care costs. Therefore, we aim to establish if individual diurnal cycling of environmental light and noise levels improves cognitive outcomes of very preterm infants compared to more constant background lighting and noise. We are undertaking a multicentre, prospective, randomised, open, blinded end-point (PROBE) parallel controlled trial that assesses the effect of non-invasive application of eye masks and ear muffs for 10 hours per night via measurements of neurodevelopmental, social, psychological, physiological, and economic outcomes. We hypothesise that diurnal cycling of light and noise commenced from birth and continued until discharge home will improve the cognitive score (Bayley Scales of Infant Development (BSID) 4th edition), in infants born at < 32 w gestation. Primary outcome will be a mean difference of 4 points in the cognitive score on BSID-4 at 2 years corrected postnatal age. Sample size to achieve 90 % power and alpha 0.05 is 954 infants, assuming a standard deviation of 15 points, a 10 % loss to follow-up and a 30 % adjustment for multiple births. Secondary outcomes will target survival, anthropometry and growth, key neonatal morbidities (BPD/NEC/ROP/Sepsis/IVH), length of hospital stay, survival, Bayley 4 subscores, infant behaviour, sleep, hormonal and clock gene circadian profiles, health service utilisation, core health economic analyses and primary carer mental health and sleep, .

REINSTATE trial: Resolution of Elements Influencing Nutritional STatus After criTical illnEss
Expand descriptionNutrition delivery to critically ill patients is largely inadequate, resulting in muscle wasting and reduced physical function in the long-term. While factors such as delayed gastric emptying and reduced glucose absorption are relatively well described early in critical illness, there is a paucity of data on the resolution of these derangements. Further, nutrition intake post-extubation and on the post intensive care unit (ICU) ward are also inadequate. Whether factors that are known to influence nutritional intake in ICU are still prevalent post-ICU requires exploration.

Impact of unhealthy food vs. pro-health sponsorship options on young adults' food preferences
Expand descriptionMarketing of unhealthy foods through elite sport sponsorship is pervasive in Australia, with massive audience reach. This study aims to examine spectator responses to unhealthy food sponsorship and investigate the utility of alternative, pro-health sport sponsorship options to promote healthier food choices to young adults. The four sponsorship scenarios tested will be: (A) non-food sponsorship (control); (B) unhealthy food sponsorship; (C) healthier food sponsorship; and (D) obesity prevention campaign sponsorship. Participants will be exposed to their assigned sponsorship stimuli; complete a distractor task; then answer a series of questions assessing their brand awareness, attitudes and image perceptions, event-sponsor-fit perceptions, and their preference for food sponsor products. The findings from this study will lay the foundation for developing public health-oriented sport sponsorship policies targeted toward healthy eating and obesity prevention.

The N-ICE Trial: A trial of N-Acetyl-Cysteine (NAC) for methamphetamine dependence
Expand descriptionWe will test the safety and efficacy of N-Acetyl-Cysteine (NAC) as a pharmacotherapy for methamphetamine dependence using a double-blind placebo-controlled randomised controlled trial (RCT). The trial will involve 180 participants receiving either 12 weeks of take-home oral NAC (2,400 mg daily) or equivalent placebo. There are three trial sites (Wollongong, Geelong and Melbourne). This is a Phase 2b trial that is powered to confirm whether NAC has a clinically relevant benefit on methamphetamine use and a range of related clinical outcomes. Primary hypothesis: Daily oral NAC delivered as a take home medication will reduce methamphetamine use measured as (a) days of methamphetamine use, and (b) methamphetamine in weekly saliva tests, during 12 weeks of active treatment relative to placebo. Secondary hypotheses: Daily oral NAC delivered as a take home medication will, relative to placebo: - reduce the severity of methamphetamine dependence, craving for methamphetamine, methamphetamine withdrawal symptoms and psychiatric symptoms (affective symptoms, positive psychotic symptoms and hostility), - have an acceptable adverse event profile, and - not significantly increase the use of other substances (including alcohol, tobacco, cannabis, heroin and cocaine).

A Phase I study to investigate pharmacokinetics, safety, and tolerability of two single doses of EU-C-001 given as slow intravenous infusions in healthy female subjects
Expand descriptionThis is a phase 1 study in healthy subjects. It is planned to develop the drug for reducing pressure in the brain of patients with a traumatic brain injury (TBI). Increased pressure following TBI can lead to death or can cause permanent disability. There are currently no medications that are approved for improving outcomes after TBI. The drug will also be tested for improving clinical outcome in patients that suffered a concussion. The study drug being evaluated is called EU-C-001 and is being developed by an Australian company called PresSura Neuro. Studies in animals have shown that EU-C-001 may reduce pressure in the brain. Therefore, it is thought that EU-C-001 may improve outcomes in patients with TBI by increasing the amount of oxygen available to brain tissue. In other studies it was shown that the EU-C-001 may also have potential to improve outcomes in patients with concussion. Single oral administrations up to 180 mg EU-C-001 and single intravenous administrations up to 90 mg EU-C-001 have been administered to healthy male subjects. The safety, tolerability and pharmacokinetic information is not yet available in females. Therefore, the present study is planned to investigate the safety, tolerability and the pharmacokinetic characteristics of the medication given intravenously in healthy female subjects and will compare the result from a historical data set obtained from studies in healthy male subjects.

Determination of Calreticulin (CALR) mutation status based on peripheral blood immunohistochemistry and flow cytometry.
Expand descriptionThe purpose of this study is to determine if new blood testing methods are effective in determining Calreticulin mutation status. Who is it for? You may be eligible for this study if you are over the age of 18, have a known myeloproliferative disorder and are currently undergoing regular blood tests at St Vincent’s Hospital. Study details Participants will continue to undergo regular testing by clinicians. However, an additional 10mL of blood will be collected during your routine venesection. This sample will then be tested for Calreticulin mutation using both of the following tests: 1. Flow cytometry 2. Immunohistochemistry The results will then be compared to results from the current gold standard method used for testing for Calreticulin mutations. It is hoped that results from this study would allow testing for Calreticulin mutation to be done rapidly, locally and non-invasively.

Preoperative Microvascular Protection in Patients Undergoing Major Abdominal Surgery
Expand descriptionAlbumin and dexamethasone are often administered to patients undergoing major surgery. Despite these drugs being commonly used, it is not known how they impact on the stress response to surgery. Albumin is an intravenous fluid made up of a normal physiological protein (albumin) in a salt solution, that is routinely administered to patients having major surgery. It is TGA approved and readily available in Australia. Dexamethasone is a steroid medication, often used in many types of surgery to reduce the risk of nausea and vomiting. It also has anti-inflammatory and pain relieving effects. It is also TGA approved and readily available in Australia. This pilot study aims to determine if giving albumin and dexamethasone immediately prior to surgery can reduce the stress response from surgery. Stress, or the inflammatory response during surgery can result in damage to the microvasculature (the smallest blood vessels in the body). By protecting these small vessels with dexamethasone and albumin, we hope to reduce the effects caused by the systemic inflammatory response that accompanies major surgery. The study is a collaboration between 5 major hospitals that specialize in major abdominal surgery. These are Austin Health, Peter MacCallum Cancer Center, Warringal Private Hospital, Knox Private Hospital and Auckland City Hospital. Importantly, for all patients in the study, standard of care will be maintained during anaesthesia, surgery, and the entire perioperative process and there will be NO deviation at any stage from acceptable routine care. For this pilot study, patients undergoing 3 different types of major abdominal surgery will be randomized (allocated by chance) into two groups. The ‘Treatment Group’ will receive 16mg of dexamethasone and 100ml of 20% albumin solution 30-60minutes prior to the start of surgery, and a solution of 4% albumin to meet their ongoing fluid requirements during surgery. The ‘Control Group’ will receive no dexamethasone and 100ml of a standard balanced salt solution, with further balanced salt solution to meet their fluid requirements during surgery. We will compare levels of Syndecan-1 (a marker of microvascular function) between the two groups at 5 different time points during and up to 48 hours after the operation to assess if microvascular function differs between the groups. A total of 72 subjects will be included in the study.
