Resynchronisation of the Biological Clock Using Exposure to Low Oxygen Levels in Humans: An Exploratory Study

Exposure to reduced oxygen levels occurs in several real-world contexts, such as during air travel or altitude exposure, and emerging evidence suggests that hypoxia may interact with molecular pathways involved in circadian regulation. This exploratory study investigated the effe...

Hospitalization of Children in Foster Homes: A Canadian Cohort Study

BACKGROUND AND OBJECTIVES: In Canada, approximately 4% to 7% of children live in a foster home during their childhood. This study reports on hospitalizations of children in foster homes, with the hypothesis that rates of hospitalization are higher for children with foster home ex...

Laser Printing of Plasmonic Color Images in Polymer-Embedded Nanorod Films

Nanoscale structures that support surface plasmons have been used extensively to create colorful images at the surface of materials. Approaches used include dispersion of nanoparticles, the dewetting of thin films, e-beam lithography to precisely control the size and distribution...

Solving problems increases provisioning efficiency, enhancing reproductive success in male great tits

Abstract The ecological and selective processes acting on cognitive traits have received recent attention because of the potentially key role of cognition in rapid behavioural adjustments in response to environmental variation. Innovation, a cognitive process involved in the deve...

Objectives To test the performance of the 2025 ASAS-SPARTAN Revised Classification Criteria for Axial Spondyloarthritis (axSpA)[1] in a multicenter inception cohort of patients with undiagnosed chronic back pain attending dermatology, ophthalmology, and gastroenterology clinics w...

Defining Difficult-to-Treat Rheumatoid Arthritis in Routine Care: Comparative Performance of Published Criteria and Description of Early and Late D2T-RA Phenotypes

Objectives Despite advances in treat-to-target strategies, a subset of rheumatoid arthritis (RA) patients remains refractory to therapy, described as difficult-to-treat RA (D2T-RA). The European Alliance of Associations for Rheumatology (EULAR) has proposed formal criteria for D2...

Exploring Training Needs to Facilitate Shared Decision Making in Juvenile Idiopathic Arthritis Symptom Management and the Use of the JIA Option Map

Objectives Our team developed the JIA Option Map, a web-based patient decision aid (PDA) designed to support shared decision-making (SDM) for juvenile idiopathic arthritis (JIA) symptom management. Since training for health care providers (HCP) can enhance SDM and the use of PDAs...

Exploring Decisional Factors to Include Approaches in a Patient Decision Aid for Juvenile Idiopathic Arthritis Symptom Management

Objectives Youth with juvenile idiopathic arthritis (JIA) experience physical and mental health symptoms that negatively impact their participation in daily life activities. The JIA Option Map is a web-based patient decision aid (PDA) created to facilitate decision-making for JIA...
