Inherited bleeding disorders are most commonly due to coagulation factor deficiency. While bleeding disorders like haemophilia are readily diagnosed, patients with inherited abnormalities in platelet number and function often remain undiagnosed for prolonged periods. This project provides a diagnostic platform to provide a specific genetic diagnosis to these individuals and families with a bleeding disorder allowing better management of their symptoms and allowing rational prescribing of blood products. The consumer representative identified accuracy of diagnosis and quality of life as the most important issues.

This trial aims to determine changes in the control of breathing in the supine posture (lying flat on your back), with bronchodilator therapy and ventilatory support and the link with breathing discomfort and sleep in people with chronic obstructive pulmonary disease. Non-invasive recordings of brain activity, termed electroencephalography, will be used to determine changes in the control of breathing that occur with change from seated to supine posture, after bronchodilator therapy and after ventilatory support via a face mask. The link between changes in the control of breathing with breathing discomfort during these conditions (assessed by questionnaire) and sleep quality (assessed by an under-mattress sensor and sleep diaries). Baseline lung function and questionnaire responses will be collected.

Pathological production of polyols after brain injury may be a cause for secondary neurological injury. Polyols are osmotic and neurotoxic, which may have detrimental outcomes for critically ill individuals with brain injury. This study will be a biospecimen analysis of cerebrospinal fluid in health volunteers, aiming to quantify polyol concentrations. The results will act as a control group to compare with populations studied in other trials investigating polyol production in ICU patients with traumatic brain injury, subarachnoid haemorrhage, and pain conditions.

This study aims to compare rates of complications, dwell time and treatment completion with midclavicular catheters and peripherally inserted central catheters (PICCs). We hypothesize that in adults, midclavicular catheters (MCCs) will be associated with lower rates of complications compared with PICCs, similar rates of treatment completion, and similar dwell time.

Vasoactive drugs are amongst the most commonly prescribed medications for critically ill adult patients in intensive care units (ICU). Noradrenaline is the universally recommended first-line agent for such patients but questions remain around the timing of commencing additional (adjunctive) vasoactive medications, such as vasopressin. This study will determine whether a large-scale stepped wedge trial implementing and evaluating a strategy of using vasopressin as an early adjunctive vasopressor in the ICU is feasible. We will also collect provisional data on the physiological effects, efficacy and safety of early adjunctive vasopressin in adults receiving vasopressors in the ICU.

The world’s population is getting older, and ageing is associated with a decline in cognition and blood circulation within the brain. This means that more people will require additional care or move into aged care facilities. Studies have shown that both cannabidiol (a non-intoxicating part of the cannabis plant) and vitamin E have the ability to improve blood flow throughout the body, particularly in the brain. This is important, because our brain requires a large percentage of our blood flow to supply it with all the oxygen and energy it needs. Through a randomised controlled trial, we will investigate the effect of cannabidiol and vitamin E on brain blood vessel function to improve cognition, over 16 weeks, anticipating that it will improve blood vessel function and cognition. It is hypothesised that both cannabidiol and vitamin E will each improve cognition and in this cohort by improving cerebrovascular function, as well as improving cardiovascular function and general physiological and psychological markers of health. It is also hypothesised that the combination of cannabidiol and vitamin E will improve cerebrovascular function and cognition as well as improving cardiovascular function and general physiological and psychological markers of health, beyond what either product achieves on its own. Your participation will help us determine if cannabidiol and vitamin E could be supplements that improve brain health. This work may help benefit yourself and others within your community to increase quality of life.

Adolescence is a crucial period for prevention efforts as numerous social and biological changes confer risk for mental health and substance use challenges, which can have enduring impacts across the life course. The Mind Your Mate Program was developed with youth, education and health experts to promote peer support, encourage help-seeking and prevent mental health and substance use problems in adolescents. Building upon the success of the pilot trial, which found significant reductions in adolescent depression, the program has been expanded into a comprehensive universal, school-based program. The new program will be evaluated through a cluster-randomised controlled trial conducted across secondary schools in Australia. We hypothesise, that compared to students receiving health education as usual, students in schools allocated to the program will show improved mental health knowledge and reduced mental ill-health risk.

This clinical trial looks into investigating the effectiveness of a novel group intervention programme for mild traumatic brain injury (mTBI or concussion) to help us provide better clinical care. The study involves a three-part intervention programme comprising 1) a neuropsychological examination measuring different aspects of cognition; 2) 6x1.5-hour weekly group sessions covering a range of information about mTBI, including skills that you can use to assist with recovery; and 3) up to 6x1-hour weekly individual sessions, in which some of the issues specific to your recovery will be addressed. Participants will also be asked to fill out a range of questionnaires at pre- and post-intervention, as well as a remotely administered 3-month follow-up, to track recovery progress.

This study is a randomised open-label trial of adminstering either Flucelvax (standard) and Fluad (adjuvanted) influenza vaccines. We will enrol healthy participants aged 18-50 years who did not receive any influenza vaccine in the 15 months preceding study entry and who would like to receive a 2026 influenza vaccine. We will randomise participants to receive either Flucelvax or Fluad Influenza vaccines and have blood, saliva and nasal fluid tests to follow their immune responses to the vaccines. Participants have study visits just prior to vaccination and on days 6, 28 and 180 post-vaccination. We are testing the idea that younger people who receive an adjuvanted influenza vaccine may have stronger immune reponses against a larger range of influenza virus strains

We are studying how much blood pressure and blood sugar vary across nights in people who have both obstructive sleep apnoea and high blood pressure. We want to see whether using a continuous positive airway pressure (CPAP) machine every night for about eight hours can help keep these levels more stable. We will look at how CPAP affects people’s blood pressure, blood sugar, and energy levels, both in a controlled laboratory setting and during everyday life at home. We will also explore whether factors such as diet, sleep habits, or teeth grinding influence these changes.
