OBJECTIVE Although the systematic measurement of disease activity facilitates clinical decision making in rheumatoid arthritis (RA), no recommendations currently exist on which measures should be applied in clinical practice in the US. The American College of Rheumatology (ACR) convened a Working Group (WG) to comprehensively evaluate the validity,(More)
In two normative studies, we examined daily scripted activities from the perspective that scripts are frequency-based knowledge structures. In Study 1 individuals recorded their daily activities for 7 consecutive days. Fifteen activities that were reported with low, moderate, and high frequency were selected for Study 2, in which individuals generated a(More)
BACKGROUND Herpes zoster occurs more commonly in patients taking immunosuppressive medications, although the risk associated with different medications is poorly understood. METHODS We conducted a retrospective cohort study involving 20,357 patients who were followed in the Veterans Affairs healthcare system and treated for rheumatoid arthritis from(More)
The signaling lymphocytic activation molecule (SLAM)/CD150 family includes a family of chromosome 1-encoded cell surface molecules with costimulatory functions mediated in part by the adaptor protein SH2D1A (SLAM-associated protein, SAP). Deficiency in SH2D1A protects mice from an experimental model of lupus, including the development of(More)
OBJECTIVE The co-occurrence of rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity in rheumatoid arthritis (RA) is well described. However, the mechanisms underlying the potential interaction between these 2 distinct autoantibodies have not been well defined. The aim of this study was to evaluate the epidemiologic and molecular(More)
INTRODUCTION A deletion polymorphism in glutathione S-transferase Mu-1 (GSTM1-null) has previously been implicated to play a role in rheumatoid arthritis (RA) risk and progression, although no prior investigations have examined its associations with anticitrullinated protein antibody (ACPA) positivity. The purpose of this study was to examine the(More)
OBJECTIVE To determine the incidence of and risk factors for non-melanoma skin cancer (NMSC) in a national cohort of veterans with RA. METHODS We examined skin cancer risk in a cohort of 20 648 patients with RA derived from the Department of Veterans' Affairs (VA) national administrative databases. The cohort was divided into two medication groups:(More)
OBJECTIVE To provide evidence-based recommendations for the treatment of patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (SpA). METHODS A core group led the development of the recommendations, starting with the treatment questions. A literature review group conducted systematic literature reviews of studies that(More)
OBJECTIVES To examine the all-cause mortality rate and factors associated with mortality in US veteran men with RA. METHODS Men with RA were enrolled and followed until death or censoring. Vital status was ascertained through systematic record review and standardized mortality ratios (SMRs) were calculated using US life tables for men. Multivariate Cox(More)
OBJECTIVE This study evaluates whether depression is a risk factor for incident myocardial infarction (MI) in Department of Veterans Affairs (VA) patients with rheumatoid arthritis (RA) between 30 and 79 years of age. METHODS We used a retrospective cohort study of 15,634 patients with RA. Diagnoses and sociodemographic data were obtained from VA(More)
