Safety and Efficacy of the Application of Photobiomodulation (PBM) on Intensive Care Unit (ICU) Patients with Acute Delirium
Patients who are admitted to the Intensive Care Unit (ICU) are at high risk of developing delirium, a form of acute brain failure which can manifest with agitation and confusion, and/or withdrawal from interaction. When delirium occurs, the overall prognosis for the hospital stay is adversely affected, and there is a risk of future cognitive decline and dementia. There is no gold standard treatment for delirium. Its presentation in people admitted to the Intensive Care Unit (ICU) is complex and it complicates treatment of other conditions requiring ICU admission. ICU patients with acute delirium can be a danger to themselves and others. Presence of delirium confers an adverse prognosis for ICU patients, and management of delirium when it occurs is largely supportive. There is an urgent need for the exploration of new treatment modalities to manage acute delirium in critically ill patients. This exploratory study assesses the application of a helmet (twice daily from Monday to Friday, for up to 4 weeks) that delivers pulses of near-infrared light to the brain in patients admitted to the Mater Adult Intensive Care Service who are diagnosed with acute delirium. Four slightly different protocols (with variations of application parameters) will be used. Patients enrolled in the study will have assessment of brainwaves using Quantitative Electroencephalography (QEEG) before and after treatment. Other behavioural and physiological observations that are routinely collected and recorded in the medical record in ICU patients will also be assessed.

Longitudinal Head Injury Outcome Study
The Longitudinal Head Injury Outcome Project is a long-standing research project investigating the functional, cognitive, behavioural and physical and emotional outcomes of patients who have sustained a TBI from the time of injury up to 30 years after their injury. This study aims to provide comprehensive information regarding the difficulties experienced by these individuals and their families over long periods of time after injury. This information can be used to establish the needs of individuals with TBI, identify predictors of outcome, develop rehabilitation programs to improve outcome, inform TAC policy and provide ongoing service to TBI patients.

Walking without Pain: Piloting a digital program for people 50 years and over experiencing chronic low back pain
This project aims to gain insight into the effect of a digital physical activity intervention (tailored walking program and physical activity coaching) and an online psychological program (Pain Course) in people 50 years and over living with chronic low back pain (CLBP). Does a tailored walking intervention combined with an online psychological program improve physical activity levels measured by daily walk time in people 50 years and older with chronic low back pain (CLBP)? We hypothesise that our intervention will lead to an increase in physical activity levels (daily walk time) over 6-months. This project is a two-arm, single-blinded, interventional, randomised control trial with a 14-week intervention period and a 6-month follow up.

A Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of PLX-4545 in Healthy Volunteers
The purpose of this study is to assess the safety, tolerability (how well an individual can tolerate a drug), pharmacokinetics (how a drug moves into, through and out of the body) and pharmacodynamics (the effect of a drug on the body) of single and multiple ascending doses of PLX-4545 in healthy volunteers. PLX-4545 may be indicated for use in patients with cancer that present as solid tumours, but a trial of the drug in healthy volunteers is needed before trials in cancer patients can proceed. Who is it for? You may be eligible for this study if you are aged 18 to 65 years and are in good general health without a clinically significant medical history. People who have been diagnosed with cancer will not be eligible for this study. Study details This trial will be conducted across three parts. In the first study (Part 1), healthy volunteer participants will be assigned by chance to receive either a single dose of PLX-4545 or placebo, to be taken after a fasting period. All participants will have their vital signs checked (heart rate, blood pressure, temperature, etc), and will provide blood samples for testing. If the drug appears safe, additional participants will be assigned by chance to receive a larger single dose of PLX-4545 or placebo, followed by blood testing. This will continue until a maximum safe dose is determined. In the second study (Part 2), healthy volunteer participants will be assigned by chance to receive either multiple doses of PLX-4545 or placebo to be taken once per day for 14 days. All participants will have their vital signs checked (heart rate, blood pressure, temperature, etc), and will provide blood samples for testing. If the drug appears safe, additional participants will be assigned by chance to receive a larger daily dose of PLX-4545 or placebo for 14 days, followed by blood testing. This will continue until a maximum safe dose is determined. In the third study (Part 3), healthy volunteer participants will be assigned by chance to receive either a single dose of PLX-4545 after fasting conditions or immediately after a high fat meal. All participants will have their vital signs checked and will provide blood samples for testing to determine the effect of food on PLX-4545. Once participants have completed their first dose, they will be asked to take another dose either after fasting or a meal, whichever they did not do for the first dose round. It is hoped this research will determine the maximum dose of PLX-4545 that can be administered safely without causing severe reactions. The healthy volunteer study will help define the starting doses of PLX-4545 to be evaluated in a subsequent Phase 1 clinical trial in cancer patients for determining the recommended dose to support a Phase 2 clinical study.

Closed loop transcranial alternating current stimulation in depression (tACS-Depression)
Major depressive disorder (MDD) is a severe and common illness. It has been well established that approximately 30% of patients with MDD have an inadequate response to standard medication and psychological therapies. These patients remain disabled for long time as treatment options are limited. Current brain stimulation treatment options for MDD are costly and can be inconvenient as they may require daily trips to clinics for long treatment sessions that happen over the course of 6 weeks or more. Additionally, we are technically constrained in what we can achieve and current technologies and approach to treat MDD have generally used a ‘one size fits all’ method. Transcranial alternating current stimulation (tACS) is a novel, non-invasive brain stimulation method that delivers a weak electrical current to the brain and is able to modulate brain oscillatory activity. tACS has potential to change the lives of patients with MDD by specifically targeting brain circuits and oscillations relevant to MDD. Our approach aims to change the ‘one size fits all’ method by conducting a proof-of-concept study demonstrating the feasibility, clinical and electrophysiological impact of closed-loop theta tACS. The study will specifically aim to confirm whether theta oscillations and mood in patients with MDD can be successfully modulated by tACS. We hypothesize that a series of personalized theta tACS sessions applied to the dorsolateral prefrontal cortex (DLPFC) in patients with depression can modulate the following to a greater degree in participants who are receiving active treatment compared to sham stimulation: 1. Modulate theta activity at rest and during cognitive tasks (measured using EEG) on and emotional Stroop task and a working memory task 2. Modulate behavioral performance on both the emotional Stroop and working memory tasks. 3. Modulate depression symptoms (clinician rated and self-reported).

A Program to Foster Motivation for Physical Activity Among Adults in Substance Use Recovery
Substance use disorders (SUDs) pose a major public health concern. While initial research suggests that physical activity (PA) might benefit individuals in SUD treatment, we still lack definitive evidence. High relapse rates, comorbidity, and motivation challenges among SUD patients often hinder PA interventions. In this study, we will assess the impact and practicality of a motivational program to boost PA motivation and maintenance among residents with SUDs in a Western Australian treatment facility. The study will span over 28 weeks, including baseline (six weeks), intervention (ten weeks), and maintenance (twelve weeks) periods. We will use daily assessments to track PA motivation, substance use cravings, and emotional state. Thereby, we will explore how the intervention may influence these variables change across the study phases. These findings may guide future research and help apply successful PA interventions to broader SUD populations.

Schema therapy for people with binge eating disorders
This study will provide a course of schema therapy to adults with eating disorders featuring binge-eating. The treatment will be tailored to certain aspects of personality: early maladaptive schemas, perceived parenting style and temperament. The aim of the study is to determine whether this treatment reduces eating disorder symptoms and behaviours and whether there is a relationship between change in early maladaptive schemas and eating disorder symptoms. People aged 18 or older with eating disorders featuring binge eating (e.g., bulimia nervosa, binge eating disorder) will be eligible to participate in the study. The study will be conducted at multiple sites, including two eating disorder services in the UK and three private practice centres in Australia. The treatment includes 25 x 1-hour sessions over approximately 30 weeks. Participants will complete questionnaire measures before starting treatment, halfway through treatment, at the end of treatment and at 3- and 6-months after treatment is complete. To understand participants' perspective of the treatment, an optional qualitative interview will be conducted after treatment is complete.
