Linkage of a de-identified United States rheumatoid arthritis registry with administrative data to facilitate comparative effectiveness research.
In order to address a gap in linkage methodology, the researchers sought to link a large, de-identified outpatient registry of patients with rheumatoid arthritis with national Medicare administrative claims data. The purpose of their report was to describe the methods and validity of this linkage.

Non-viral opportunistic infections in new users of tumour necrosis factor inhibitor therapy: results of the SAfety Assessment of Biologic ThERapy (SABER) study.
The purpose of this paper was to determine, among patients with autoimmune diseases in the USA, whether the risk of non-viral opportunistic infections (OI) was increased among new users of tumour necrosis factor alpha inhibitors (TNFI), when compared to users of non-biological agents used for active disease. The investigators concluded that in the USA, the rate of non-viral OI was higher among new users of TNFI with autoimmune diseases compared to non-biological disease-modifying antirheumatic drugs users.

Use of oral and subcutaneous methotrexate in rheumatoid arthritis patients in the United States.
The researchers aimed to examine the epidemiology of methotrexate (MTX) use among rheumatoid arthritis patients initiating MTX, including dosing, method of administration (oral versus subcutaneous (SC)) , and persistence. They also compare the effectiveness of 2 strategies in regard to delaying or avoiding use of biologic agents: switching to SC MTX or adding another nonbiologic disease-modifying antirheumatic drug.

Associations between pressure-pain threshold, symptoms, and radiographic knee and hip osteoarthritis.
The researchers sought to determine the association between generalized evoked pressure pain sensitivity with distal pressure–pain threshold and the presence, severity, or number of involved knee/hip joints with radiographic osteoarthritis or related symptoms. They found that as a participant’s sensitivity for pressure pain decreased, there were several significant associations with presence, severity, and number of joints with symptoms, regardless of the knee or hip joint.
