Regular physical activity, including running, is recommended based on known cardiovascular and mortality benefits. However, controversy exists regarding whether running can be harmful to knees. The purpose of this study is to evaluate the relationship of running with knee pain, radiographic osteoarthritis, and symptomatic osteoarthritis.
To determine whether lower thigh muscle specific strength increases risk of incident radiographic knee osteoarthritis (RKOA), and whether there exists a sex-specific relationship between thigh muscle specific strength and BMI.
To investigate the association between (i) smoking status and (ii) smoking cessation and mortality in patients with rheumatoid arthritis (RA).
Objective Moderate to severe chronic pain affects one in five adults. Pain may increase the risk of mortality but the relationship is unclear. This study investigated whether mortality risk was influenced by pain phenotype, characterised by pain extent or pain impact on daily life. Methods The study population was drawn from two large population cohorts of adults aged ≥50 years; the English Longitudinal Study of Ageing (ELSA) (n=6324) and the North Staffordshire Osteoarthritis Project (NorStOP) (n=10985). Survival analyses (Cox’s proportional hazard models) estimated the risk of mortality in participants reporting “any pain” and then separately according to the extent of pain (total number of pain sites; widespread pain according to American College of Rheumatology (ACR) criteria; widespread pain according to Manchester criteria) and pain impact on daily life (pain interference; and often troubled with pain). Models were cumulatively adjusted for age, sex, education and wealth/adequacy of income. Results After adjustments, the report of any pain (MRR 1.06, 95% CI (0.95, 1.19)) or having widespread pain (ACR 1.07 (0.92, 1.23) or Manchester 1.16 (0.99, 1.36)) was not associated with an increased risk of mortality. Participants who were often troubled with pain (1.29 (1.12, 1.49)) and those that reported “quite a bit” (1.38 (1.20,1.59)) and “extreme” (1.88 (1.54, 2.29)) pain interference had an increased risk of all-cause mortality. Conclusion Pain that interferes with daily life, rather than pain per se was associated with an increased risk of mortality. Future studies should investigate the mechanisms through which pain increases mortality risk. This article is protected by copyright. All rights reserved.
Studies have demonstrated a link between COPD and inflammation, raising the question whether chronic inflammatory conditions, such as RA, predispose to COPD. Our objective was to evaluate the risk of incident COPD hospitalization in RA compared to the general population.
To compare persistence and adherence to triple therapy with nonbiologic disease-modifying antirheumatic drugs (DMARDs) methotrexate (MTX), hydroxychloroquine, and sulfasalazine, versus a tumor necrosis factor inhibitor plus MTX (TNFi+MTX) in patients with rheumatoid arthritis (RA).
To investigate the contribution of symptoms of depression to future episodes of low back pain (LBP).
OBJECTIVE: Our objective was to estimate and compare the prevalence of fibromyalgia by two different methods, in Olmsted County, Minnesota. METHODS: The first method was a retrospective review of medical records of potential cases of fibromyalgia in Olmsted County using Rochester Epidemiology Project (from January 1, 2005, to December 31, 2009) to estimate the prevalence of diagnosed fibromyalgia in clinical practice. The second method was a random survey of adults in Olmsted County using the fibromyalgia research survey criteria to estimate the percentage of responders who met fibromyalgia research survey criteria. RESULTS: Of the 3,410 potential patients identified by the first method, 1,115 had a fibromyalgia diagnosis documented in the medical record by a health care provider. The age- and sex-adjusted prevalence of diagnosed fibromyalgia by this method was 1.1%. By the second method, of the 2,994 people who received the survey by mail, 830 (27.6%) responded and 44 (5.3%) met fibromyalgia research survey criteria. The age- and sex-adjusted prevalence of fibromyalgia in the general population of Olmsted County by this method was estimated at 6.4%. CONCLUSION: To the best of our knowledge, this is the first report of the rate at which fibromyalgia is being diagnosed in a community. This is also the first report of prevalence as assessed by the fibromyalgia research survey criteria. Our results suggest that patients, particularly men, who meet the fibromyalgia research survey criteria are unlikely to have been given a diagnosis of fibromyalgia. © 2012 by the American College of Rheumatology.
Knee osteoarthritis (OA) is a commonly undiagnosed condition and care is often not provided. Pharmacists are uniquely placed for launching a multidisciplinary intervention for knee OA.
To evaluate the impact of concomitant methotrexate (MTX) on subcutaneous (SC) abatacept immunogenicity, and to assess safety and efficacy.
