The long-term clinical outcomes and associated prognostic factors in contactin-associated protein-like 2 (CASPR2)-antibody diseases are unknown. A total of 75 participants with CASPR2 antibodies were longitudinally assessed for disability, quality-of-life, and chronic pain. Although most symptoms improved within 6 months of treatment, neuropathic pain and fatigue were the most immunotherapy refractory, and persisted for up to 6 years.

Background: Health systems across Europe are facing a workforce crisis, with some experiencing severe shortages of doctors. In response, many are exploring greater task-sharing, across established professions, such as doctors, nurses, and pharmacists, with patients and carers, and with new occupational groups, in particular ones that can assist doctors and relieve their workload.

Case Presentation: In the early 2000s the United Kingdom created a new occupational role, that of physician assistant.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease with the age at which characteristic symptoms manifest strongly influenced by inherited HTT CAG length. Somatic CAG expansion occurs throughout life and understanding the impact of somatic expansion on neurodegeneration is key to developing therapeutic targets. In 57 HD gene expanded (HDGE) individuals, ~23 years before their predicted clinical motor diagnosis, no significant decline in clinical, cognitive or neuropsychiatric function was observed over 4.

The manner in which neural activity unfolds over time is thought to be central to sensory, motor and cognitive functions in the brain. Network models have long posited that the brain's computations involve time courses of activity that are shaped by the underlying network. A prediction from this view is that the activity time courses should be difficult to violate.

In vitro and animal studies have suggested that inoculation with herpes simplex virus 1 (HSV-1) can lead to amyloid deposits, hyperphosphorylation of tau, and/or neuronal loss. Here, we studied the association between HSV-1 and Alzheimer's disease biomarkers in humans. Our sample included 182 participants at risk of cognitive decline from the Multidomain Alzheimer Preventive Trial who had HSV-1 plasma serology and an amyloid PET scan.

Animal models that accurately reflect COVID-19 are vital for understanding mechanisms of disease and advancing development of improved vaccines and therapeutics. Pigs are increasingly recognized as valuable models for human disease due to their genetic, anatomical, physiological, and immunological similarities to humans, and they present a more ethically viable alternative to non-human primates. However, pigs are not susceptible to SARS-CoV-2 infection which limits their utility as a model.

Dual inhibition of the angiopoietin (Ang)/Tie and vascular endothelial growth factor (VEGF) signalling pathways in patients with retinal diseases, such as neovascular age-related macular degeneration (nAMD) and diabetic macular oedema (DME), may induce greater vascular stability and contribute to increased treatment efficacy and durability compared with treatments that only target the VEGF pathway. Faricimab, a bispecific intravitreal agent that inhibits both VEGF and Ang-2, is the first injectable ophthalmic drug to achieve treatment intervals of up to 16 weeks in Phase 3 studies for nAMD and DME while exhibiting improvements in visual acuity and retinal thickness. Data from real-world studies have supported the safety, visual and anatomic benefits and durability of faricimab, even in patients who were previously treated with other intravitreal agents.

Scoping review: The effects of diet, physical activity and sleep on motor and physical fatigue in people with multiple sclerosis.

Neuroscience

January 2025

Alliance for Research in Exercise, Nutrition and Activity (ARENA), Allied Health and Human Performance, University of South Australia, South Australia, Australia.

Physical and motor fatigue are debilitating symptoms common in multiple sclerosis (MS). Lifestyle interventions may be effective in managing MS-related fatigue. This scoping review aims to: (i) identify and summarise lifestyle interventions including those focused on diet, physical activity, and sleep, or multicomponent interventions for physical and motor fatigue management in MS; and (ii) provide recommendations for future research in this area.

Outcomes after medical treatment for primary aldosteronism: an international consensus and analysis of treatment response in an international cohort.

Lancet Diabetes Endocrinol

January 2025

Centre for Endocrinology and Metabolism, Hudson Institute of Medical Research, Clayton, VIC, Australia; Department of Endocrinology, Monash Health, Clayton, VIC, Australia.

Background: Primary aldosteronism can be treated medically but there is no standardised method to evaluate treatment outcomes. We aimed to develop criteria for assessing the outcomes of targeted medical treatment of primary aldosteronism, analyse outcomes across an international cohort, and identify factors associated with a complete treatment response.

Methods: An international panel of 31 primary aldosteronism experts used the Delphi method to reach consensus on the definition of complete, partial, or absent biochemical and clinical outcomes of medical treatment of primary aldosteronism.

Background: Aspirin is a simple, globally available medication that has been shown to reduce the incidence of colorectal cancer. We aimed to evaluate the safety and efficacy of aspirin in the secondary prevention of colorectal cancer.

Methods: This phase 3, randomised, double-blind, placebo-controlled trial was conducted at 66 centres across 11 countries and territories (ten in Asia-Pacific; one in the Middle East).

Bi-allelic KICS2 mutations impair KICSTOR complex-mediated mTORC1 regulation, causing intellectual disability and epilepsy.

Am J Hum Genet

January 2025

Institute of Medical Genetics and Applied Genomics, University of Tübingen, Tübingen, Germany; Center for Rare Disease, University of Tübingen, Tübingen, Germany; Genomics for Health in Africa (GHA), Africa-Europe Cluster of Research Excellence (CoRE). Electronic address:

Nutrient-dependent mTORC1 regulation upon amino acid deprivation is mediated by the KICSTOR complex, comprising SZT2, KPTN, ITFG2, and KICS2, recruiting GATOR1 to lysosomes. Previously, pathogenic SZT2 and KPTN variants have been associated with autosomal recessive intellectual disability and epileptic encephalopathy. We identified bi-allelic KICS2 variants in eleven affected individuals presenting with intellectual disability and epilepsy.

A constitutive interferon-high immunophenotype defines response to immunotherapy in colorectal cancer.

Cancer Cell

January 2025

Cancer Systems Biology Laboratory, The Francis Crick Institute, London NW1 1AT, UK; Centre for Cancer Evolution, Bart's Cancer Institute, Queen Mary University London, London EC1M 6AU, UK. Electronic address:

Fewer than 50% of metastatic deficient mismatch repair (dMMR) colorectal cancer (CRC) patients respond to immune checkpoint inhibition (ICI). Identifying and expanding this patient population remains a pressing clinical need. Here, we report that an interferon-high immunophenotype locally enriched in cytotoxic lymphocytes and antigen-presenting macrophages is required for response.

Background: Determining trauma as an act of Self-directed violence (SDV) or from high risk or unclear behaviours is challenging for trauma clinicians and may be affected by patient sex and mechanism of injury. The aim of this study was to examine the differences in characteristics and outcomes between those who have intentionally directed violence towards themselves with those of unclear intent, within a regional trauma system.

Methods: Data was collected between January 2018 and December 2021 in patients who had been identified as a result of either self-directed violence (SDV) defined as any intentional act that can cause injury to one's self, including death or participated in high-risk behaviours, where the intent was unclear (UI).

Permeability is a measure of the degree to which cells can transport molecules across biological barriers. Units of permeability are distance per unit time (typically cm/s), where accurate measurements are needed to define drug delivery in homeostasis and to model dysfunction occurring during disease. This perspective offers a set of community-led guidelines to benchmark permeability data across multidisciplinary approaches and different biological contexts.
