To determine the effectiveness and cost-effectiveness of anti-tumor necrosis factor (anti-TNF) medications in a real-world environment for the treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) using the Health Assessment Questionnaire (HAQ). ⋯ We obtained data on the effectiveness and cost-effectiveness of anti-TNF drugs using the HAQ score, which is known to be an excellent predictor of work disability, morbidity, and mortality. HAQ scores decreased with treatment and were sustained throughout the 3-5 years of followup. The NNT of approximately 2 seems favorable and was similar between diseases.

To test the efficacies of a strategy for preventing tuberculosis (TB) in Indian patients with inflammatory rheumatic diseases (IRD) treated with tumor necrosis factor-alpha (TNF-alpha) inhibitor. ⋯ With the use of these 4 TB screening tests in India, where TB is highly prevalent, TB could be excluded with a high degree of certainty (NPV 0.97). However, as even this combination of tests has only moderate sensitivity and specificity and poor PPV for detecting TB, vigilance may be advisable even if only one of the tests is positive.

Comparative Study
Greater perceived helplessness in osteoarthritis predicts outcome of joint replacement surgery.
To determine if there is a difference between male and female patients in their perceived control of osteoarthritis (OA) symptoms at the time of joint replacement surgery, as measured by the Arthritis Helplessness Index (AHI), and how this helplessness affects surgical outcomes at 1 year. ⋯ Interventions to improve control over arthritis symptoms should be studied with the goal of improving surgical outcomes.

Meta Analysis Comparative Study
Land-based exercise for osteoarthritis of the knee: a metaanalysis of randomized controlled trials.
To determine if clinical guidelines recommending therapeutic exercise for people with knee osteoarthritis (OA) are supported by rigorous scientific evidence. To explore whether the magnitude of treatment benefit reported in randomized controlled trials (RCT) is associated with exercise dosage or study methodology. ⋯ There is evidence that land-based therapeutic exercise has at least short-term benefit in terms of reduced knee pain and physical disability for people with knee OA. The magnitude of the treatment effect was significantly associated with the number of direct supervision occasions provided and study methodology (assessor blinding, adequate allocation concealment).

Health related quality of life (HRQOL) is an important patient-reported outcome in systemic lupus erythematosus (SLE). We evaluated the psychometric properties of 2 widely used preference-based generic HRQOL measures, EuroQol-5D (EQ-5D) and Short Form-6D (SF-6D), among United States patients with SLE. ⋯ The SF-6D and EQ-5D exhibited satisfactory psychometric properties for use among US patients with SLE. Measures of disease activity and damage were weakly correlated with HRQOL, suggesting that HRQOL is an important complementary source of information about patients with SLE.
