Factors Associated With Fibromyalgia Diagnosis Among People Meeting Criteria: Results From UK Biobank

open access: yesArthritis Care &Research, EarlyView.
Objective The diagnosis of fibromyalgia (FM) is challenging due to the absence of definitive biomarkers, numerous overlapping comorbidities, and its reliance on patient‐reported symptoms. Discrepancies between diagnostic criteria and clinical practice imply the possibility of diagnostic biases, complicating timely and accurate identification.

The flexible urban grid: adaptation, expansion and evolution in Philadelphia's city block morphology

open access: yes, 2023
This study examines the evolution of Philadelphia’s city block morphology between 1683, when the city was planned by William Penn, and 1900, when urban expansion abandoned the grid. The study uses both quantitative and qualitative assessment.
