Stiff Person Syndrome (SPS) is a rare disorder that causes pain, stiffness and spasms in the back, trunk, arms legs. It can be a difficult condition for doctors to diagnose as the key symptoms are common with many potential causes, and there is no single test that proves a person has the condition. Blood tests can be helpful in some cases and abnormalities in a particular test called the exteroceptive reflex test has been described in the condition. It is not known, however, how accurate exteroceptive reflex testing is in the diagnosis of SPS. The purpose of this study is to get more information about whether the exteroceptive reflex test can help doctors diagnose stiff-person syndrome and distinguish this from other neurological problems which present with pain or stiffness in muscles, people who take medication which make other reflexes more prominent (selective serotonin reuptake inhibitors and selective serotonin and noradrenaline reuptake inhibitors), and from healthy individuals. Exteroceptive reflex testing involves a doctor or neurophysiology scientist recording signals from several muscles in the back and legs by placing small disposable recording electrodes on the skin. Muscle contraction is measured after nerves in the wrist and ankle are activated with low-level electrical current. The test takes approximately 15 minutes, and does not cause any harm to the nerves, muscles or other parts of the body.

The primary objective of the study is to demonstrate of whether Avelle® Negative Pressure Wound Therapy helps better management of chronic wound and exudate when used in accordance with the Instructions for Use. Exudate is the fluid that leaks out of a wound. The secondary objective is to measure ongoing safety of the Avelle® Negative Pressure Wound Therapy system. Medications, drugs and devices have to be approved for use by the Australian Federal Government. The Avelle® Negative Pressure Wound Therapy System is approved in Australia to treat low to moderately exuding (leaking fluid) wounds that would benefit from a Negative Pressure Wound Therapy device. It is indicated to treat different types of wounds, one which is chronic wounds like ulcers. This study will gather information about the device’s ability to manage wound fluid and progress made in the healing of the wound. The hypothesis is that the Avelle™ Negative Pressure Wound Therapy system will help the wound close and manage the fluid that leaks from the wound. The hypothesis is that the Avelle™ Negative Pressure Wound Therapy system will help the wound close and manage the fluid that leaks from the wound.

Until recent years, right heart dysfunction (RHD) has been paid little attention due to a combination of it being challenging to assess, not having unified diagnostic criteria and the apparent robustness of the right ventricle. However more recent data combined with improved imaging techniques have changed this attitude. This project aims to create a longitudinal cardiopulmonary profile of patients who have suffered from right heart dysfunction to to determine if there is correlation between RHD and physical limitation/symptom burden following hospital discharge. It will use inpatient data (clinical and echocardiographic) as well as longitudinal outpatient data (qualitative and combined CPET-SE) to map the course of these patients. This longitudinal observational data will be hypothesis generating, a first step in considering how an acute phase intervention may change the natural history of this insult.

This project will investigate the effects of theacrine, a supplement that is similar to caffeine. It is well shown in the literature that caffeine can improve cognitive performance, which refers to the ability of an individual to use their mental processes to perform tasks such as thinking, problem-solving, and decision making. With the similarities to caffeine, it is suggested that theacrine may be able to improve cognitive performance without some of the side effects associated with caffeine including sleep disturbance. However, as theacrine is a relatively new supplement, there is limited investigations to support these findings. Therefore, this project aims to investigate the effect of theacrine dose and timing combinations on cognitive performance across the day and subsequent night-time sleep. Using a placebo-controlled, double-blind, randomised crossover design, participants will complete seven conditions separated by a six-day washout period. Conditions will include a placebo (glucose) and a low (100 mg) and high dose (400 mg) of theacrine administered 12, eight, and four hours prior to bedtime. These timepoints reflect consumption in the morning, afternoon, and evening. With the repeated measures design, it is estimated that 21 participants will be required. Participants will be healthy males aged between 18 and 40 years with no reported medical or sleep condition and a daily habitual caffeine consumption between 2-5mg/kg/day.

This study is investigating a new cancer treatment drug, RX108-A, to determine whether it is safe and effective for patients with locally advanced or metastatic solid tumors. Who is it for?: You may be eligible for this study if you are an adult aged 18 years or older and you have been diagnosed with locally advanced or metastatic solid tumors and you have failed at least one standard of care therapy, or you were intolerant to a standard of care therapy, or you have refused such treatment. Study details: This study will firstly enroll participants into a dose escalation study. Participants who choose to enroll in the escalation study will be assigned a specific number of tablets to take each day for 3 weeks, followed by a 1 week rest. Participants will be asked to keep a diary of any side effects that they experience while taking the experimental treatment, and may be asked to stop taking the tablets if they experience any severe side effects. Participants will also be asked to provide blood samples at 4 different times during their 3-week treatment cycle. New groups of participants will be enrolled to test each higher dose of the experimental treatment until the best tolerated dose is identified. After the best tolerated dose has been identified, a new group of up to 9 participants will be enrolled for the dose expansion study. Participants who choose to enroll in the expansion study will be assigned a specific number of tablets to take each day for 3 weeks, followed by a 1 week rest. Participants in this study will be asked to keep taking the tablets for 3-week cycles for up to 7 months, and will be asked to provide blood samples at different timepoints during their first three 3-week treatment cycles. It is hoped this research will determine the highest safe dose of RX108-A that reduces the growth of tumors in people with locally advanced or metastatic solid tumors. If this study finds that RX108-A is safe and effective, it may be expanded to a larger trial of people with locally advanced or metastatic solid tumors.

The purpose of the study is to demonstrate the safety and efficacy of the LensOne device, which allows surgeons to implant a single piece, posterior chamber IOL in patients with aphakia. It is hypothesized that the LensOne device can provide surgeons and patients a safe and stable solution for fixating a posterior chamber IOL when there is insufficient capsular and zonular support. This study aims to establish the safety of the LensOne device and to provide surgeons with a consensus method of securing a posterior chamber IOl when there is insufficient capsular or zonular support.

ECMO is a form of advanced life support that is used in patients with heart or lung failure when other forms of medical treatment have failed. These patients are some of the sickest within Australian and New Zealand Intensive Care units (ICUs) and often remain unconscious for weeks. Whilst provision of nutrition via feeding tube into the stomach (enteral nutrition) is an accepted standard of care there remain crucial gaps in our understanding of the best way to provide nutrition to this population. Available data indicates that these patients consistently receive less nutrition than they are prescribed, and they experience frequent interruptions to nutrition delivery. Moreover, the outcomes in these patients are poor with significant losses of muscle mass and strength resulting in disability that persists well beyond hospital discharge. It is thought that nutrition delivery across hospitalisation may influence recovery, however this needs to be understood, with no information currently available for the period on the hospital ward. This study is designed to describe current nutrition provision and practices across hospitalisation for the first time in patients receiving ECMO. It is expected that the findings from this study will enable the develop of strategies to improve the delivery of nutrition in this high-risk population and inform the design of future research.

Trans young people often have poor mental health outcomes and high rates of depression and anxiety. These poor mental health outcomes have been shown to be associated with the abuse, rejection and discrimination that many trans young people experience due to anti-trans attitudes in broader society, referred to as minority stressors. This study will evaluate the Trans Adolescent Group ThErapy for Alleviating Minority stress (TAG TEAM) intervention, which is a group cognitive behavioural therapy (CBT) program that focuses on experiences of minority stress and aims to improve symptoms of depression and anxiety. The results of the study will be used to inform the clinical care of trans young people.

This will be a phase 1, first-in-human, open-label, 3-period, 3-treatment crossover design study to evaluate the food effects and relative bioavailability of 2 formulations of PTC607 in 8 healthy participants.

This is an observational tele trial to determine the effectiveness of Sambucol in the management of the symptoms of the common cold and flu-like illnesses in children and adolescents aged between 2 years and 17 years who are already committed to consuming Sambucol as part of their own routine self-care (with parental consent and monitoring). Sambucol Black Elderberry Cold & Flu is a liquid that has an extract of Elderberry that is safe for children and teens to consume to help relieve their cold and flu symptoms. This same Elderberry extract has been shown to be useful in helping to resolve cold and flu symptoms like coughing, sneezing and headaches in adults. This study is testing if the same extract in Sambucol Black Elderberry Cold & Flu is useful for children and adolescents with cold and flu symptoms or not. The study will be conducted online via a study app and will measure the duration and severity of cold symptoms of participants who are taking Sambucol Black Elderberry Cold & Flu, until the illness resolves. The researchers expect that Sambucol will significantly reduce the severity of the symptoms of the common cold in comparison to existing data on children with cold and flu symptoms. It is also expected that Sambucol will reduce the severity of the symptoms of the common cold in children comparable to reductions observed in clinical trials with adults taking Sambucol, and significantly greater than adults taking placebo.
