The Trial.

Mrs. Ellis (a pseudonym) is a 57-year-old woman with a 10-year history of rheumatoid arthritis (RA) and a previous episode of transverse myelitis with residual pain and weakness.After the patient's insufficient response to methotrexate (MTX) and upon realizing that tumor necrosis factor inhibitors are relatively contraindicated in demyelinating disease, I wrote a prescription for abatacept (ABA), which could conceivably help both her RA and her transverse myelitis.

Opioid use surrounding diagnosis and follow-up in patients with ankylosing spondylitis, psoriatic arthritis, and rheumatoid arthritis: Results from US claims databases.

Objective: To describe patients' use of opioids in the year preceding and year following new diagnosis of ankylosing spondylitis (AS), psoriatic arthritis (PsA), or rheumatoid arthritis (RA), compared with patients without the/se diseases.

Methods: This study used US IBM MarketScan Commercial Claims and Encounters (CCAE) and Medicaid data and included three cohorts, comprised of incident cases of AS, PsA, or RA (2010-2017). Three matched comparator patients (without the incident disease) were selected for each patient within the disease cohort.

Consensus on the definitions and descriptions of the domains of the OMERACT Core Outcome Set for shared decision making interventions in rheumatology trials.

Objective: To gain consensus on the definitions and descriptions of the domains of the Outcome Measures in Rheumatology (OMERACT) core domain set for rheumatology trials evaluating shared decision making (SDM) interventions.

Methods: Following the OMERACT Handbook methods, our Working Group (WG), comprised of 90 members, including 17 patient research partners (PRPs) and 73 clinicians and researchers, had six virtual meetings in addition to email exchanges to develop draft definitions and descriptions. The WG then conducted an international survey of its members to gain consensus on the definitions and descriptions.

Generating a list of potentially important contextual factors covering randomized trials, cohorts, and measurement property studies: An OMERACT initiative.

Objectives: To generate candidates for contextual factors (CFs) for each CF type (i.e., Effect Modifying Contextual Factors (EM-CFs), Outcome Influencing Contextual Factors (OI-CFs), and Measurement Affecting Contextual Factors (MA-CFs)) considered important within rheumatology.
