Utility of Synovial Fluid Biomarkers for Culture-Positive Septic Arthritis in a Lyme Disease-Endemic Region.

Objective: To evaluate the performance of synovial fluid biomarkers to identify children with culture-positive septic arthritis.

Methods: We identified children 6 months to 18 years old presenting to a single emergency department between 2007 and 2022 undergoing evaluation for septic arthritis defined by having a synovial fluid culture obtained. Our primary outcome was septic arthritis defined by a positive synovial fluid culture.

Biomarkers for Pediatric Bacterial Musculoskeletal Infections in Lyme Disease-Endemic Regions.

Objectives: Bacterial musculoskeletal infections (MSKIs) are challenging to diagnose because of the clinical overlap with other conditions, including Lyme arthritis. We evaluated the performance of blood biomarkers for the diagnosis of MSKIs in Lyme disease-endemic regions.

Methods: We conducted a secondary analysis of a prospective cohort study of children 1 to 21 years old with monoarthritis presenting to 1 of 8 Pedi Lyme Net emergency departments for evaluation of potential Lyme disease.

Learner Handoffs Within Clinical Rotations: From the Resident Perspective.

Purpose: Competency-based medical education relies on repeated longitudinal assessments of learners. Frequent attending physician transitions within clinical rotations present a significant barrier to the educational continuity required in competency-based medical education. Learner handoffs (LHs), or the transfer of information regarding learners on a team among faculty supervisors, is a potential solution.

Astrochemical evolution along star formation: Overview of the IRAM Large Program ASAI.

Evidence is mounting that the small bodies of our Solar System, such as comets and asteroids, have at least partially inherited their chemical composition from the first phases of the Solar System formation. It then appears that the molecular complexity of these small bodies is most likely related to the earliest stages of star formation. It is therefore important to characterize and to understand how the chemical evolution changes with solar-type protostellar evolution.
