Factors associated with variability in recovery after mild traumatic brain injury among adults referred to outpatient concussion clinics

BACKGROUND: To understand factors associated with symptom and disability recovery trajectories among adults referred to outpatient clinics after mild traumatic brain injury. METHODS: Adults (n = 110; mean age 39 years, 36% men), were assessed at clinic intake (baseline mean 6.5 w...

The Perfectionistic Self-Presentation Scale—Short Form (PSPS-SF): Development and Validation

This study aimed to develop and evaluate the psychometric properties of a brief version of the Perfectionistic Self-Presentation Scale (PSPS), a measure of the interpersonal expression of perfectionism. Adult participants (N = 2223; Mage = 36.67) from three samples completed all...

Beyond underrepresentation: narratives of identity and healing among Indigenous post-secondary student-athletes

Indigenous student-athletes remain underrepresented in post-secondary sport, yet limited research has examined how they experience and make meaning of participation within sporting and educational contexts. Guided by narrative inquiry and Clandinin and Connelly’s three-dimensiona...

A Systematic Survey of Smart Contract Fuzzing: Methods, Techniques, and Architectures for Ethereum and Beyond

Blockchain architectures increasingly rely on smart contracts as programmable execution components, yet the security challenges they introduce remain only partially addressed. Fuzz testing has emerged as one of the leading automated techniques for smart contract vulnerability dis...

A grounded theory study of return-to-contact following concussion in Canadian adolescent girls rugby

Drawing on qualitative interviews with adolescent girl rugby players, coaches, and healthcare professionals, this study explored the psychosocial processes through which return-to-contact following concussion is negotiated in Canadian adolescent girls rugby. Data collection and a...

Enabling employment: findings from a qualitative study on disability and employment in Canada, United States, United Kingdom, France and Belgium

Despite the UN CRDP, national anti-discrimination laws, and government employment programs, the ‘disability employment gap’ remains in most countries. This article outlines the results of a research project that examined the factors that enable disabled people to obtain and maint...

Incidence, Risk Factors and Management of Adverse Events in Contemporary Real‐World Care of Children with Juvenile Idiopathic Arthritis

OBJECTIVE: We describe the frequency, risk factors, severity, and management of actionable and serious adverse events (AAE and SAE) in children with newly diagnosed Juvenile Idiopathic Arthritis (JIA) in Canada. METHODS: We enrolled patients within 3 months of JIA diagnosis in th...

Modelling the simultaneous adsorption of two competing species

In this paper, we develop a mathematically consistent analytical framework to describe the simultaneous adsorption of two competing species in a packed column, accounting for adsorption, desorption and competitive replacement. Starting from previous work on the capture of a singl...

Postoperative pain and 12-month periapical healing after Er: YAG laser–activated versus ultrasonic irrigation: a randomized controlled trial

Abstract Background This randomized controlled clinical trial evaluated contemporary irrigation activation strategies by integrating patient-reported postoperative pain with 12-month radiographic healing outcomes. Er: YAG laser–activated irrigation using photon-induced photoacous...

Utilization of Carbon Fiber Spinal Instrumentation in Primary Spinal Tumors: Outcome Analysis from the AO Spine Primary Tumor Research and Outcomes Network

Background The use of carbon fiber-reinforced polyetheretherketone (CFR-PEEK) instrumentation in spinal surgery has emerged as an alternative to traditional titanium-based implants in recent years. This study aims to evaluate the use and performance of carbon fiber instrumentatio...

Soft sensor design using domain-adversarial Gaussian processes—A transfer learning framework

The main objective of this paper is to develop a soft sensor for prediction of quality variables when training and test data come from similar but different distributions. The challenge is to develop a soft sensor when only limited labeled data are available, which requires trans...

Heterogeneous social participation profiles and socioecological correlates among community-dwelling older adults: a latent profile analysis

Abstract Background Social participation in later life is often summarized using an aggregate score, which may obscure distinct configurations of everyday, social, and volunteering activities. This study aimed to identify latent social participation profiles among community-dwell...

Sex & Gender Science: integrating the social with the biological

Abstract For decades, researchers have largely studied aspects of sex and gender separately; the former as a basic science and the latter as a social construct with real world consequences, including health inequities. In recent years, as our collective understanding of how the b...

Pharmacological Management of Opioid Use Disorder: A Systematic Review and Network Meta-Analysis: Prise en charge pharmacologique du trouble de l'usage des opiacés : revue systématique et méta-analyse en réseau

Objective To assess the comparative benefits and harms of opioid substitution and antagonist therapies (OSATs) for opioid use disorder (OUD) using a network meta-analysis (NMA) of randomized controlled trials (RCTs). Data Sources Medline, EMBASE, PubMed, PsycINFO, Web of Science,...

Fundamental movement skills among children participating in community sport programs in a northern Canadian city: implications for equitable access and physical literacy development

Fundamental movement skills (FMS) are an important component of physical literacy and are associated with children’s physical activity participation and longer-term health. However, many children demonstrate suboptimal motor competence, and opportunities for FMS development may v...

AANEM Consensus‐Based Guideline for Grading the Severity of Carpal Tunnel Syndrome

ABSTRACT Electrodiagnostic (EDX) reports for patients with carpal tunnel syndrome (CTS) often include a description of severity, but considerable variability in approach creates confusion for referring physicians, patients, and EDX practitioners. The purpose of this project was t...

Balancing data quality and participant burden: a comparative analysis of abbreviated vs extended symptom diaries in the CanTreatCOVID trial

Abstract Background Symptom diaries are widely used in acute respiratory infection trials to capture patient-reported symptom severity and recovery. Longer questionnaires may provide a more complete clinical picture but can increase participant burden and reduce adherence. Eviden...

Flavoglycans: Evidence for Covalent Proanthocyanidin–Polysaccharide Linkages in Western Redcedar Bark

Abstract We investigated covalent linkages between proanthocyanidins (PAs) and cell wall polysaccharides in western redcedar bark (Thuja plicata Donn), a tannin-rich forestry co-product that has potential as a functional food ingredient. An alcohol-insoluble residue (AIR; 1.0% w/...

Spontaneous gallbladder perforation: An under-recognized complication in patients with decompensated liver cirrhosis

Abstract Background: Gallbladder perforation is a rare but life-threatening condition with high mortality. Patients with decompensated liver cirrhosis may be at increased risk; however, spontaneous or occult gallbladder perforation in this population is poorly recognized. This ca...

Identifying thermally tolerant bull kelp ( Nereocystis luetkeana ) source populations for restoration under climate change

Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains...
