This article presents the CONSORT (consolidated standards of reporting trials) extension for cluster randomised crossover trials. A cluster randomised crossover trial involves randomisation of groups of individuals (known as clusters) to different sequences of interventions over time. The design has gained popularity in settings where cluster randomisation is required because it can largely overcome the loss in power due to clustering in parallel cluster trials.

The story of David Ferrier's demonstration at the International Medical Congress in London in August 1881 of a monkey experimentally rendered hemiplegic by a focal surgical brain lesion-prompting Charcot's observation, "C'est un malade!"-is well known as a seminal event in the history of the localization of functions in the cerebral cortex. Less well known is the fact that, on the same occasion, Ferrier demonstrated a second monkey, known as monkey F, apparently deaf as a consequence of bilateral temporo-sphenoidal brain lesions. The purpose of this article is, first, to give a chronological account of this demonstration and subsequent related events, including Ferrier's trial under the Vivisection Act, the publication of the pathological findings in the animal's brain, the dispute about the localization of the "auditory centre" with Edward Schäfer, and the first glimmerings of human homologues of cortical deafness.

The MIR-NAT MAPT-AS1 does not regulate Tau expression in human neurons.

PLoS One

January 2025

Neuroscience Discovery, Janssen Research & Development, Janssen Pharmaceutica, Beerse, Belgium.

The MAPT gene encodes Tau protein, a member of the large family of microtubule-associated proteins. Tau forms large insoluble aggregates that are toxic to neurons in several neurological disorders, and neurofibrillary Tau tangles represent a key pathological hallmark of Alzheimer's disease (AD) and other tauopathies. Lowering Tau expression levels constitutes a potential treatment for AD but the mechanisms that regulate Tau expression at the transcriptional or translational level are not well understood.

Patient reported outcome measures (PROMs) capture patients' views of their health status and the use of PROMs as part of standard care of children and young people has the potential to improve communication between patients/carers and clinicians and the quality of care. Electronic systems for the collection of or access to PROMs and integrating PROMs into electronic health records facilitates their implementation in routine care and could help maximise their value. Yet little is known about the technical aspects of implementation including the electronic systems available for collection and capture and how this may influence the value of PROMs in routine care which this scoping review aims to explore.

Article Synopsis
  • Allogeneic haematopoietic stem cell transplantation (alloHSCT) shows high survival rates (90% overall survival) in adolescents and adults with severe inborn errors of immunity (IEI), as assessed in a study of 82 patients.
  • The study found that pre-transplant immune dysregulation (measured by the IDDA v2.1 score) and the haematopoietic cell transplantation comorbidity index (HCT-CI) score significantly affected transplant outcomes, including overall survival and event-free survival.
  • Notably, a portion of patients with a high IDDA v2.1 score and low HCT-CI score indicates that existing risk assessments may underestimate the risks of alloHSCT, highlighting

Beyond Traditional Body Composition Metrics: Load-Capacity Indices Emerge as Predictors of Cardiometabolic Outcomes - A Systematic Review and Meta-Analysis.

Adv Nutr

January 2025

School of Population Health, Faculty of Health Science, Curtin University, Perth, WA, Australia; Dementia Centre of Excellence, Curtin enAble Institute, Faculty of Health Sciences, Curtin University, Perth, WA, Australia.

The adaptive and independent interrelationships between different body composition components have been identified as crucial determinants of disease risk. Based on this concept, the load-capacity model of body composition, which utilizes measurements obtained through non-anthropometric techniques such as dual-energy X-ray absorptiometry (DXA), was proposed. This model is typically operationalized as the ratio of metabolic load (adipose mass) to metabolic capacity (lean mass).
