Cardiovascular-kidney-metabolic (CKM) syndrome is a term that is increasingly used to describe interconnected conditions that lead to poor health outcomes, including cardiovascular disease, chronic kidney disease, type 2 diabetes, and obesity. Historically, there have been very few targeted pharmacotherapies available that have changed cardiovascular outcomes for people with CKM syndromes; however, over the past decade, new pharmacologic options have rapidly expanded, with strong evidence for cardiovascular and kidney protective benefits in CKM conditions. Of note, sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists have emerged as key therapeutic options and are now widely guideline-endorsed.

Current Practices for Mental Fatigue Quantification and Induction in Movement Science: Introducing the SPeCIFY Guidelines.

Sports Med

September 2025

Faculty of Physical Education and Physiotherapy, Human Physiology and Sports Physiotherapy Research Group, Vrije Universiteit Brussel, Pleinlaan 2, 1050, Brussels, Belgium.

Mental fatigue (MF) is a complex phenomenon with significant implications for human performance, for which there are numerous studies investigating the effects of MF. Nevertheless, there is considerable variability in the approaches used to induce and quantify MF, making it hard to compare findings across studies and draw well-supported conclusions. This review addresses the methodological variability in the induction and quantification methods of MF in movement science in the following ways: on the one hand, by providing an overview of task design strategies to induce MF, emphasizing the importance of tailoring task duration, difficulty, and nature to individual participants and specific research contexts; on the other hand, by providing an overview of current methods used to quantify MF, including behavioural, subjective, and physiological measures, and highlighting the strengths and limitations of each.

Alzheimers Dement

September 2025

Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Introduction: In observational studies of preclinical AD, an arbitrary "baseline" can obscure where an individual is located along a theoretical continuum. Optimizing longitudinal trajectories can distill multiple, non-linearly distributed observations into a single metric and inform where an individual may be along the disease course.

Methods: We developed a cognitive time (c-time) metric based on longitudinal cognitive data (mean = 7.

Macroevolutionary role reversals in the earliest radiation of bony fishes.

Curr Biol

August 2025

Museum of Paleontology and Department of Earth and Environmental Sciences, University of Michigan, 1105 North University Avenue, Ann Arbor, MI 48109, USA; The Natural History Museum, Cromwell Road, London SW7 5BD, UK.

The evolution of jaws is hypothesized to have fueled radiations among vertebrates, contributing to their overwhelming success in the present day. Past work shows rapid early expansion of diversity in jaw structure in many lineages; however, the evolutionary dynamics underlying this pattern are unclear and hindered by the lack of a robust comparative framework. Here, using a macroevolutionary approach, we explore the diversification of lower jaws in early bony fishes, a major contributor to this initial radiation.

Toxins (Basel)

July 2025

Department of Physiotherapy, Epworth Rehabilitation, Epworth Healthcare, Richmond, Melbourne 3121, Australia.

Botulinum neurotoxin-A (BoNT-A) injections are effective in reducing focal limb spasticity; however, their impact on strength and active function needs to be established. This review was a secondary analysis aimed at evaluating changes to active function in the context of muscle strength changes following BoNT-A intramuscular injection for adult upper and lower limb spasticity. The original review searched eight databases (CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, Google Scholar, MEDLINE, PEDro, PubMed, Web of Science) and was conducted with methodology that followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines as described in section 6.

Atrial fibrillation (AF) is increasingly diagnosed early, close to its first occurrence due to: (i) increased public awareness with self-screening; (ii) health care initiatives including population screening and opportunistic case finding; and (iii) increased use and surveillance of implantable cardiac devices. At its onset, AF is often low burden, and cardiovascular co-morbidities may be absent or at an early stage. Thus, the management of recent-onset AF has become an issue of growing importance.

Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), Barcelona, Spain.

Pavlovian fear conditioning is a fundamental process in both health and disease. We investigate its neural correlates and sources of variability using harmonized functional magnetic resonance imaging data from 2199 individuals across nine countries, including 1888 healthy individuals and 311 with anxiety-related or depressive disorders. Using mega-analysis and normative modeling, we show that fear conditioning consistently engages brain regions within the "central autonomic-interoceptive" or "salience" network.

Hypoxanthine-guanine-(xanthine) phosphoribosyltransferase [HG(X)PRT] is an excellent target for the development of new drugs to treat parasitic and bacterial infections as well as MYC-dependent triple-negative breast cancer. Inhibitors include compounds that mimic the transition state of the catalytic reaction and analogs of the two products of the reaction, the nucleoside monophosphates and pyrophosphate. One type of chemistry explored here is the design of purine-based C1'-branched acyclic nucleoside phosphonates bearing diverse structural attachments (secondary linkers) on the C1' atom.

A mechanistic kinetic model has been developed and validated for Cu(II)/AA (ascorbic acid) and Cu(II)/HO/AA systems under varying chloride concentrations and circumneutral pH. While the Cu(II)/AA system degraded the selected target contaminant (formate) via Cu(III) generation through a Fenton-like mechanism, observed efficiencies were inadequate for practical water treatment across a broad range of chloride concentrations. This limitation stemmed from insufficient HO production, leading to low Cu(III) concentrations, and scavenging of Cu(III) by AA and its oxidation products.

Gene expression shapes the brain's functional connectome, yet it is unclear whether genes linked to the same disorder converge on shared networks. We introduce gene network mapping-a framework combining spatial transcriptomics with normative functional connectivity to identify networks associated with gene expression. By generating -network maps, we captured distributed connectivity patterns for individual genes.
