Terminology for describing the 24-h cycle of physical activity, sedentary behaviour, and sleep: a scoping review

Abstract Background Physical activity, sedentary behaviour, and sleep are three behaviours which occupy the 24-h cycle and interact to influence a multitude of health outcomes. Different terms are currently used to describe these behaviours collectively (e.g., movement behaviours...

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability

ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, m...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food...

Annotated genome assemblies of two temperate North American dung beetles, Canthon chalcites and Phanaeus vindex

Dung beetles serve as cultivators of their natural habitats, improving soil health and functions in both natural and anthropogenic environments. Despite their ecological importance, whole genome sequences for Scarabaeinae are limited. Here, we present the draft annotated genome a...

Trans-affirming leaders’ professional capital: a critical mixed-methods study of educational policies, organizational practices and leadership on trans school workers' health

Purpose This study examines how policies, workplace climate and leadership contribute to trans PK-12 school workers' health and overall well-being. Design Using a critical mixed-methods design led by queer and trans scholars, we developed an online survey for trans school workers...

Frailty and Surgical Invasiveness Are Independently Associated with Complications in Pediatric Spinal Deformity Surgery

Background: The purposes of this study were to determine whether frailty and surgical invasiveness are independently associated with perioperative outcomes and to describe the outcome rates when these 2 risk domains are considered together in pediatric patients undergoing spinal...

Endovascular Thrombectomy for Cerebral Venous Thrombosis: Current Status and Future Directions

Abstract Cerebral venous thrombosis (CVT) represents a relatively rare cause of stroke, yet it carries an overall rate of death or dependency of up to 15%. The mainstay of its management is therapeutic anticoagulation, either subcutaneously or intravenously in the acute phase, fo...

Application of a dynamic wound closure device in orthopaedic trauma patients following fasciotomy: A level-1 trauma center perspective and preliminary case series

Abstract The challenge of achieving delayed primary closure of fasciotomy wounds is well known, and multiple techniques of achieving either delayed primary closure or alternative forms of soft-tissue reconstruction have been described in the literature. However, a universally acc...

Morphology-based screening for sickle cell disease using low-cost automated microscopy and machine learning

Abstract Sickle cell disease (SCD) and β-thalassemia are the most common monogenic diseases, disproportionately affecting low- and middle-income countries, where low-cost and accurate diagnostic tools are needed to reduce the global disease burden. Although the sickling test is c...

Needing others to know you’re good: Narcissists’ pride in success is contingent on peer reactions.

= 3,463), participants recalled a real-life success or failure and reported their feelings of pride in response (Studies 1, 2, and 4) or experienced success in a controlled, laboratory experiment and reported pride in the success after receiving either positive or negative social...

A Novel Approach to Characterizing Patterns of Real-World Upper-Extremity Use During Walking and Activities of Daily Living in People with Subacute Stroke

In accelerometer-based measurement, the inclusion of upper extremity (UE) activity during walking can overestimate real-world functional UE use in people post-stroke. This study introduces a comprehensive, accelerometer-based approach to examining real-world UE use, including the...

Therapeutic Target Mapping to Advance Drug Repurposing for Cardiovascular Disease: A Perspective from an Explanted Heart Biobank

Background: Although cardiovascular disease (CVD) significantly impacts the quality of life of millions of patients worldwide, the high costs of developing new drugs and conducting clinical trials for CVD hinder therapeutic development in this field. Repurposing approved drugs, o...

Shielding against interpersonal threat in later life: The regulatory function of nostalgia among older adults.

= 189, age 21-78 years), older adults reported greater nostalgic engagement in response to social exclusion induced by the Cyberball game than younger adults. Furthermore, after experiencing nostalgia, compared to younger adults, older adults reported increased social engagement...

Development of an ethical resolution process and education resources: supporting equity-focused public health ethics education through community-engaged research

Healthcare ethics education is essential for supporting trainees and health professionals to build ethical reasoning skills necessary to resolve complex ethical issues, support equitable health outcomes, and promote just healthcare systems. Traditional ethical decision-making fra...

Education in a World of Broken Feedback Loops Haynes’ Keynote, PESA 2025

This essay uses “feedback” in the ecosystem sense of a flow of information, energy, or matter from a system’s output that, in a closed system, affects the input. Most of the systems in which we liv...

An audit of professional standards for sport science

Sport is a global industry with athletes supported by sport scientists who have gained the necessary education and experience. However, there is still great variety in the training and career development opportunities for novice and trainee sport scientists to develop their pract...

Frozen Brain-MRI Foundation Models Are Site Fingerprints

Frozen foundation-model (FM) embeddings are increasingly used as off-the-shelf brain-MRI representations, on theassumption that they capture anatomy. We audit what they actually encode and find that acquisition site is a large,intrinsic component of the representation. Across two...

A Multi-Scale Computational Analysis of Bucillamine Neuroprotection Against Soman Toxicity

This computational framework evaluates the neuroprotective mechanism of the dithiol antioxidant Bucillamine (and its active metabolite SA981) against Soman-induced oxidative damage. By integrating quantum chemical calculations, classical molecular dynamics, and systems-level ordi...
