Astrocytic activity in treatment-resistant and ultra-treatment-resistant schizophrenia

Astrocytic dysfunction has been implicated in schizophrenia, but biomarkers of astrocytic activity have shown inconsistent patterns. Studies on disease heterogeneity, specifically treatment-resistant schizophrenia (TRS) and ultra-treatment-resistant schizophrenia (UTRS) are lacki...

The feasibility of a tailored follow-up service for people living with stroke via a registry-based randomised controlled trial (A-LISTS)

After stroke, people report ongoing health challenges to national registries without any follow-up. We aimed to assess the feasibility of a co-designed, registry-initiated, follow-up service provided by hospitals and tailored for people reporting health-related challenges between...

Biophysical and structural characterisation of a quasi-stable toxic dimer of amyloid Aβ42 peptide tethered at position 34

Abstract Non-fibrillar oligomeric forms of amyloid β (Aβ) mediate toxicity in Alzheimer’s disease (AD) with Aβ accumulation preceding tau aggregation and synaptic damage. Aβ oligomerization is thought to initiate from the smallest stable unit, the dimer, yet structural details of...

Engineering mRNA‐LNP Medicines for the Ageing Brain: Opportunities and Challenges for Neurodegenerative Diseases

ABSTRACT Messenger RNA (mRNA) therapeutics delivered by lipid nanoparticles (LNPs) have advanced from concept to clinic at unprecedented speed, yet their promise for neurodegenerative diseases remains largely untapped. Currently intractable age‐related proteinopathies such as Alz...

Stroke clinical documentation education program in Australia and New Zealand

Background: Accurate and complete clinical documentation underpins the assignment of International Classification of Disease codes used for epidemiological research, hospital activity based funding, and health service planning. Objective: To develop, implement, and evaluate an ed...

Inclusive by design: an implementation framework for culturally responsive research advisory panels

Abstract Background Culturally and linguistically diverse (CALD) communities remain underrepresented in health research despite experiencing substantial health inequities. Community advisory panels are increasingly recommended to strengthen community engagement, cultural responsi...

Interactions between hippocampus and visceral organs in sleep and wakefulness

Abstract Exteroception is attenuated during sleep, while interoceptive signals may remain active. If so, they can trigger responses in their target areas, including the hippocampus, which is known to receive information from the internal organs and is susceptible to oversynchroni...

Efficacy and safety of fenfluramine in Dravet syndrome: The impact of patient clinical characteristics

Abstract Objective To assess the efficacy and safety of fenfluramine in patients with Dravet syndrome (DS) stratified by age, number of previously attempted antiseizure medications (ASMs), and SCN1A pathogenic variant status. Methods In this post hoc analysis, data from three ran...

Correlation of polygenic risk score and clinical phenotype in patients with genetic generalized epilepsy

Abstract Objective The polygenic risk score (PRS) for individuals with genetic generalized epilepsy (GGE) quantifies the common risk variants in genes identified in genome‐wide association studies. We hypothesized that the phenotype of GGE patients differs based on their GGE PRS....

Beyond the protocol: navigating ethics and governance in the multicentre implementation trials – the QASC Australasia and T3 Trials

OBJECTIVE: To describe and compare ethics and governance approval timelines for the Quality in Acute Stroke Care (QASC) Australasia Trial (2021-present) and Triage, Treatment, and Transfer of Patients with Stroke in Emergency Departments (T3) Trial (2012-2014), benchmarking again...

Aphasia treatment research: a decision-making tool to guide the design of phased trials from the Collaboration of Aphasia Trialists (CATs) trials for aphasia panel

Background Systematic reviews of randomised controlled trials with meta-analyses indicate that speech and language therapy for aphasia after stroke is effective in improving communication. However, high-quality evidence to identify an intervention’s target population (who), regim...

Associations between metabolic dysfunction–associated steatotic liver disease and physical and mental health–related quality of life in older adults

Metabolic dysfunction–associated steatotic liver disease (MASLD) is a common, often overlooked liver condition. Its impact on quality-of-life in older adults is not well understood. We examined the association between MASLD and physical and mental quality of life in a well-charac...

Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE): genetics, mechanisms and precision therapy

Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is a recently defined malformation of cortical development that is an important cause of childhood-onset drug-resistant epilepsy. Clinically, the epilepsies associated with MOGHE are h...
