Utilization of Glucagon-Like Peptide-1 Receptor Agonist at the Time of Total Hip Arthroplasty for Patients Who Have Morbid Obesity.

Background: Morbid obesity negatively affects outcomes after total hip arthroplasty (THA). The optimal strategy for weight loss before THA has not been identified. Recently, glucagon-like peptide-1 receptor agonists (GLP-1 RA) have become increasingly popular as an effective pharmacologic weight loss agent.

Prioritising domains of glucocorticoid therapy to measure in trials: Results from a modified delphi exercise from the OMERACT glucocorticoid impact working group.

Introduction: There is no consensus amongst patients and healthcare professionals about how to measure important adverse effects of glucocorticoids (GCs) that includes the patient's perspective. The OMERACT GC Impact working group sought to identify the domains of greatest importance to both patients and healthcare professionals for use in a proposed core outcome set.

Methods: Patients and healthcare professionals participated in a Delphi consensus exercise to rate the importance of previously identified candidate domains.

Disrupting the RNA polymerase II transcription cycle through CDK7 inhibition ameliorates inflammatory arthritis.

Macrophages are key drivers of inflammation and tissue damage in autoimmune diseases including rheumatoid arthritis. The rate-limiting step for transcription of more than 70% of inducible genes in macrophages is RNA polymerase II (Pol II) promoter-proximal pause release; however, the specific role of Pol II early elongation control in inflammation, and whether it can be modulated therapeutically, is unknown. Genetic ablation of a pause-stabilizing negative elongation factor (NELF) in macrophages did not affect baseline Pol II occupancy but enhanced the transcriptional response of paused anti-inflammatory genes to lipopolysaccharide followed by secondary attenuation of inflammatory signaling in vitro and in the K/BxN serum transfer mouse model of arthritis.

Disease Activity and Bone Microarchitectural Phenotype in Patients With Axial Spondyloarthritis.

Background: Axial spondyloarthritis (AxSpA) is a chronic rheumatic disease characterized by spine inflammation, abnormal bone growth, and paradoxically osteoporosis and vertebral fractures. The pathogenesis of skeletal deficits in this disease is poorly understood.

Purpose: We sought to evaluate volumetric bone mineral density (vBMD) and bone microarchitecture in patients with AxSpA and to identify disease-related factors associated with skeletal abnormalities.

Barriers to Total Joint Arthroplasty: A Comparison of High-Poverty and Low-Poverty Communities.

Objective: Our aim was to determine the most significant barriers to total joint arthroplasty (TJA) for people living in high-poverty communities relative to low-poverty communities.

Methods: We created a 21-question survey based on interviews with underrepresented minority patients with osteoarthritis targeting five barriers to TJA: trust in surgeon, recovery concerns, cost and/or insurance issues, fear of poor surgical outcomes, and timing considerations. Participants rated the importance of each barrier on a 5-point Likert scale, dichotomized into "very or extremely important" and "not as important.

Implementing Patient Health Questionnaire Depression Screening in Inflammatory Arthritis Clinic: Insights From a Quality Improvement Project at a Tertiary Rheumatology Center.

Objective: This quality improvement project evaluates the feasibility and sustainability of adopting the Patient Health Questionnaire (PHQ) depression screening tool into routine clinical care at a rheumatology fellows' inflammatory arthritis (IA) clinic at a large tertiary center. The aim was to achieve 50% compliance in documentation of PHQ after five months.

Methods: Providers received a 30-minute education on the importance of depression screening in patients with IA.

Periprosthetic Joint Infection in Patients With Inflammatory Arthritis: Optimal Tests to Differentiate From Flares.

Objective: Diagnosis of periprosthetic joint infection (PJI) in patients with inflammatory arthritis (IA) is challenging, as features of IA flares can mimic infection. We aimed to cross-sectionally determine if the optimal tests to diagnose PJI in osteoarthritis were present in patients with IA flares.

Methods: We enrolled patients from October 2020 to July 2022 in 3 groups: (a) PJI-total joint arthroplasty patients undergoing revision for infection, (b) IA Flare-IA patients with a flaring native joint, and (c) IA Aseptic-total joint arthroplasty patients with IA undergoing aseptic arthroplasty revision.

Training of Peer Coaches to Assist Individuals with Knee Osteoarthritis Prepare and Recover From Total Knee Replacement.

Objective: The objective of this study is to outline the training of peer coaches in the Moving Well intervention, which was designed to reduce anxiety, depression, and pain catastrophizing in patients before and after total knee replacement (TKR).

Methods: Selected peer coaches had a history of knee osteoarthritis (KOA), a TKR of 12 months or more before training, and were 60 or older. Training was primarily conducted virtually, with a later addition of one in-person session.

Temporal Trends in the Rate of Revision Total Knee Arthroplasty for Prosthetic Joint Infection.

Background: Perioperative practices have been introduced over the last decade to decrease the risk of periprosthetic joint infection (PJI). We sought to determine whether rates of revision total knee arthroplasty (TKA) for PJI decreased during the period 2006-2016.

Methods: This observational cohort study used data from the New York Statewide Planning and Research Cooperative System to identify patients undergoing TKA in 2006-2016.

Contemporary Patterns of Financial Toxicity Among Patients With Rheumatologic Disease in the United States.

Background/objective: Rheumatologic diseases encompass a group of disabling conditions that often require expensive clinical treatments and limit an individual's ability to work and maintain a steady income. The purpose of this study was to evaluate contemporary patterns of financial toxicity among patients with rheumatologic disease and assess for any associated demographic factors.

Methods: The cross-sectional National Health Interview Survey was queried from 2013 to 2018 for patients with rheumatologic disease.

PERI-operative biologic DMARD management: Stoppage or COntinuation during orthoPaEdic operations (the PERISCOPE trial) - a study protocol for a pragmatic, UK multicentre, superiority randomised controlled trial with an internal pilot, economic evaluation and nested qualitative study.

Introduction: Biological disease-modifying antirheumatic drugs (bDMARDs) have revolutionised the treatment of inflammatory arthritis (IA). However, many people with IA still require planned orthopaedic surgery to reduce pain and improve function. Currently, bDMARDs are withheld during the perioperative period due to potential infection risk.

Clonal associations between lymphocyte subsets and functional states in rheumatoid arthritis synovium.

Rheumatoid arthritis (RA) is an autoimmune disease involving antigen-specific T and B cells. Here, we perform single-cell RNA and repertoire sequencing on paired synovial tissue and blood samples from 12 seropositive RA patients. We identify clonally expanded CD4 + T cells, including CCL5+ cells and T peripheral helper (Tph) cells, which show a prominent transcriptomic signature of recent activation and effector function.

Endothelial cell sphingosine 1-phosphate receptor 1 restrains VE-cadherin cleavage and attenuates experimental inflammatory arthritis.

In rheumatoid arthritis, inflammatory mediators extravasate from blood into joints via gaps between endothelial cells (ECs), but the contribution of ECs is not known. Sphingosine 1-phosphate receptor 1 (S1PR1), widely expressed on ECs, maintains the vascular barrier. Here, we assessed the contribution of vascular integrity and EC S1PR1 signaling to joint damage in mice exposed to serum-induced arthritis (SIA).

Understanding the Influence of Single Payer Health Insurance on Socioeconomic Disparities in Total Hip Arthroplasty (THA) Utilization: A Transnational Analysis.

Objective: Access to care varies between countries. It is theorized that income-based disparities in access may be reduced in countries with universal health insurance relative to the United States, but data are currently limited. We hypothesized that income-based differences in total hip arthroplasty (THA) utilization and outcomes would be larger in the United States than in Canada.

Synovial fibroblast gene expression is associated with sensory nerve growth and pain in rheumatoid arthritis.

It has been presumed that rheumatoid arthritis (RA) joint pain is related to inflammation in the synovium; however, recent studies reveal that pain scores in patients do not correlate with synovial inflammation. We developed a machine-learning approach (graph-based gene expression module identification or GbGMI) to identify an 815-gene expression module associated with pain in synovial biopsy samples from patients with established RA who had limited synovial inflammation at arthroplasty. We then validated this finding in an independent cohort of synovial biopsy samples from patients who had early untreated RA with little inflammation.

A Novel Approach for Mixed-Methods Research Using Large Language Models: A Report Using Patients' Perspectives on Barriers to Arthroplasty.

Objective: Mixed-methods research is valuable in health care to gain insights into patient perceptions. However, analyzing textual data from interviews can be time-consuming and require multiple analysts for investigator triangulation. This study aims to explore a novel approach to investigator triangulation in mixed-methods research by employing a large language model (LLM) for analyzing data from patient interviews.

Consensus of the definitions of the OMERACT glucocorticoid impact core domain set for people with rheumatic and musculoskeletal diseases.

Background: The Outcome Measures in Rheumatology (OMERACT) Glucocorticoid (GC) Impact Working Group has been working to develop a core domain set to measure the impact of GCs on patients living with rheumatic and musculoskeletal diseases. The mandatory domains previously identified for inclusion in all clinical trials measuring the GC effects include infection, bone fragility, mood disturbance, hypertension, diabetes, weight, fatigue, and mortality. Before progressing to instrument selection, the Working Group sought to establish precise definitions of all mandatory domains within the core domain set.

Healthcare disparities: patients' perspectives on barriers to joint replacement.

Objective: Racial and ethnic disparities in arthroplasty utilization are evident, but the reasons are not known. We aimed to identify concerns that may contribute to barriers to arthroplasty from the patient's perspective.

Methods: We identified patients' concerns about arthroplasty by performing a mixed methods study.

Validation of a new glucocorticoid-specific Patient-Reported Outcome Questionnaire (the Steroid PRO).

Objectives: Glucocorticoids used in the treatment of inflammatory rheumatic conditions can impact on health-related quality of life. An underpinning qualitative study developed a long-list of candidate items for a treatment-specific patient-reported outcome (PRO) measure. The objective of this paper is to determine scale structure and psychometric properties of the Steroid PRO.

Deconstruction of rheumatoid arthritis synovium defines inflammatory subtypes.

Rheumatoid arthritis is a prototypical autoimmune disease that causes joint inflammation and destruction. There is currently no cure for rheumatoid arthritis, and the effectiveness of treatments varies across patients, suggesting an undefined pathogenic diversity. Here, to deconstruct the cell states and pathways that characterize this pathogenic heterogeneity, we profiled the full spectrum of cells in inflamed synovium from patients with rheumatoid arthritis.

Associations Between Rheumatoid Arthritis Clinical Factors and Synovial Cell Types and States.

Objective: Recent studies have uncovered diverse cell types and states in the rheumatoid arthritis (RA) synovium; however, limited data exist correlating these findings with patient-level clinical information. Using the largest cohort to date with clinical and multicell data, we determined associations between RA clinical factors with cell types and states in the RA synovium.

Methods: The Accelerated Medicines Partnership Rheumatoid Arthritis study recruited patients with active RA who were not receiving disease-modifying antirheumatic drugs (DMARDs) or who had an inadequate response to methotrexate (MTX) or tumor necrosis factor inhibitors.

2023 American College of Rheumatology and American Association of Hip and Knee Surgeons Clinical Practice Guideline for the Optimal Timing of Elective Hip or Knee Arthroplasty for Patients With Symptomatic Moderate-to-Severe Osteoarthritis or Advanced Symptomatic Osteonecrosis With Secondary Arthritis for Whom Nonoperative Therapy Is Ineffective.

Objective: To develop evidence-based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient-important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA).

Methods: We developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created.
