Background: Few studies on multiple sclerosis (MS) have explored the variability of percentage brain volume change (PBVC) measurements obtained from different clinical MRIs. In a retrospective multicentre cohort study, we quantified the variability of annualised PBVC in clinical MRIs.

Methods: Clinical MRIs of relapse-onset MS patients were assessed by icobrain.

Importance: Interventions that substantially slow neurodegeneration are needed to address the growing burden of Alzheimer disease (AD) to societies worldwide. Elevated brain iron observed in AD has been associated with accelerated cognitive decline and may be a tractable drug target.

Objective: To investigate whether the brain-permeable iron chelator deferiprone slows cognitive decline in people with AD.

Dementia is a burgeoning global problem. Novel magnetic resonance imaging (MRI) metrics beyond volumetry may bring new insight and aid clinical trial evaluation of interventions early in the Alzheimer's disease course to complement existing imaging and clinical metrics. To determine whether: (i) normalized regional sodium-MRI values (Na-SI) are better predictors of neurocognitive status than volumetry (ii) cerebral amyloid PET status improves modelling.

Article Synopsis
  • Prisons in Victoria, Australia, have implemented a statewide nurse-led model of care since 2015 to enhance hepatitis C testing and treatment among inmates, crucial for elimination efforts.
  • From 2015 to 2021, 3,133 DAA treatment courses were prescribed to 2,768 inmates, with a significant increase in prescriptions over the years and a median age of treated individuals being 39.
  • The program achieved a 93% success rate in sustained viral response (SVR12), demonstrating the effectiveness of decentralized, nurse-led initiatives in tackling hepatitis C in high-prevalence settings like prisons.

Purpose: For nearly half of patients who undergo Endovascular Thrombectomy following ischemic stroke, successful recanalisation does not guarantee a good outcome. Understanding the underlying tissue changes in the infarct tissue with the help of biomarkers specific to ischemic stroke could offer valuable insights for better treatment and patient management decisions. Using quantitative susceptibility mapping (QSM) MRI to measure cerebral iron concentration, this study aims to track the progression of iron within the infarct lesion after successful reperfusion.
