Dual Orexin Antagonism and Emotion and Affective Processing Study

In this study, the investigators will examine the effects of blocking the orexin system on human behaviour and brain function using daridorexant, a medication that inhibits orexin activity. Orexin is a brain chemical involved in regulating sleep, emotion, motivation, and stress responses, which are often disrupted in mental health disorders. Healthy volunteers will be randomly assigned to receive a single dose of daridorexant or placebo in a double-blind design. Participants will then complete behavioural and cognitive tasks assessing emotional processing, aversive learning, and executive function. The study aims to clarify the role of orexin in emotional and cognitive processes relevant to conditions such as depression and anxiety.

Remediation Program Via a "Serious Game" for the Cognitive Functions of Multiple Sclerosis Patients

The main goal of this study is to assess the effectiveness of a cognitive remediation program based on a "serious game" on the information processing speed evolution and the process of learning via episodic memory in multiple sclerosis patients.

Generation Victoria Cohort 2020s: A Statewide Longitudinal Cohort Study of Victorian Children and Their Parents

Generation Victoria (GenV) is a longitudinal, population-based study of Victorian children and their parents that will bring together data on a wide range of conditions ,exposures and outcomes. GenV blends study-collected, study-enhanced and linked data. It will be multi-purpose, supporting observational, interventional, health services and policy research within the same cohort. It is designed to address physical, mental and social issues experienced during childhood, as well as the antecedents of a wide range of diseases of ageing. It seeks to generate translatable evidence (prediction, prevention, treatments, services) to improve future wellbeing and reduce the future disease burden of children and adults. The GenV Cohort 2020s is open to all children born over a two-year period, and their parents, residing in the state of Victoria Australia. The GenV Cohort 2020s is preceded by an Advance Cohort of children born between 5 Dec 2020 and 3 October 2021, and their parents. This comprises all families recruited at GenV's Vanguard hospital (Joan Kirner Women's and Children's) and at birthing hospitals throughout Victoria as GenV scaled up to commence recruiting for the GenV Cohort 2020s. The Advance Cohort have ongoing and full participation in GenV for their lifetime unless they withdraw but may have less complete data and biosamples.

Human Learning of New Structured Information Across Time and Sleep

Acting adaptively requires quickly picking up on structure in the environment and storing the acquired knowledge for effective future use. Dominant theories of the hippocampus have focused on its ability to encode individual snapshots of experience, but the investigators and others have found evidence that it is also crucial for finding structure across experiences. The mechanisms of this essential form of learning have not been established. The investigators have developed a neural network model of the hippocampus instantiating the theory that one of its subfields can quickly encode structure using distributed representations, a powerful form of representation in which populations of neurons become responsive to multiple related features of the environment. The first aim of this project is to test predictions of this model using high resolution functional magnetic resonance imaging (fMRI) in paradigms requiring integration of information across experiences. The results will clarify fundamental mechanisms of how humans learn novel structure, adjudicating between existing models of this process, and informing further model development. There are also competing theories as to the eventual fate of new hippocampal representations. One view posits that during sleep, the hippocampus replays recent information to build longer-term distributed representations in neocortex. Another view claims that memories are directly and independently formed and consolidated within the hippocampus and neocortex. The second aim of this project is to test between these theories. The investigators will assess changes in hippocampal and cortical representations over time by re-scanning participants and tracking changes in memory at a one-week delay. Any observed changes in the brain and behavior across time, however, may be due to generic effects of time or to active processing during sleep. The third aim is thus to assess the specific causal contributions of sleep to the consolidation of structured information. The investigators will use real-time sleep electroencephalography to play sound cues to bias memory reactivation. The investigators expect that this work will clarify the anatomical substrates and, critically, the nature of the representations that support encoding and consolidation of novel structure in the environment.

Interactive Virtual Occupational Safety Training Designed for Home Healthcare Workers

Overview. The investigators will collect preliminary data on the extent to which the knowledge gained from the enhanced HH-VSTS transfers to a real-world environment. Following abbreviated use of the enhanced HH-VSTS, participants will perform a walk-through of a realistic environment to assess their learning.

Integrated Learning Support System Based on Immersive Simulated Training for Nursing Students

This study aims to evaluate the effectiveness of an Integrated Learning Support System (ILSS) in preparing undergraduate nursing students for immersive simulated training in managing drug-induced nephrotoxicity. The study hypothesizes that the ILSS, which accommodates different learning styles, will be more effective in reducing stress and anxiety compared to the standard learning model (SLM). The research will involve a parallel randomized controlled trial with 96 students from two Brazilian institutions. The students will be divided into control and experimental groups, with the latter using the ILSS in addition to SLM during preparation. The study will assess outcomes such as knowledge acquisition, skill development, and stress reduction using various instruments, including the Lasater Clinical Judgment Rubric and DASS-21. The study's findings aim to validate the ILSS as a tool to enhance learning outcomes and reduce stress and anxiety, thereby promoting better professional development and patient safety in nursing practice.

Work Package 3 Education for ICU Clinicians in Basic Palliative Care

The EPIC project aims at sustainably improving palliative care for seriously ill patients and their families in ICUs. To this aim, an interdisciplinary consortium is working together to provide a new practical palliative care model using telemedicine. The project is the first European intervention study on palliative care in the ICU using a systems- based approach with proactive patient identification, checklist and blended learning designed to meet the specific needs of ICU staff. EPIC's vision is to contribute to a change in awareness from a narrow focus on prolonging life to a more holistic approach to care. The development of blended learning for intensive care staff is the task of Work Package (WP) 3. The aim is to improve the attitude, understanding and self-confidence of ICU staff. Blended learning is to be developed and implemented for this purpose. The aim is to teach the basics of palliative care on a cognitive, affective and psychomotor level. Due to the international character of the project, it is to be developed in English with subtitles in the local languages. In addition a workshop with patient and family advisors will be conducted.
