Purpose: Studies of the relation of fibromyalgia (FM) and widespread pain (WSP) to mortality have differed as to the presence or absence of an association and the extent of cause-specific mortality. However, no studies have investigated which definitions of FM and WSP associate with mortality, nor of FM mortality in other diseases. We investigated...
Article
Background and aims Persons with chronic widespread pain (CWP) have poor medical outcomes and increased mortality. But there are no universally accepted criteria for CWP or of methods to assess it. The most common criteria come from the 1990 American College of Rheumatology (ACR) fibromyalgia (FM) criteria, but that method (WP1990) can identify CWP...

Objective: Polysymptomatic distress (PSD) is the underlying metric of fibromyalgia (FM), and levels of PSD can identify criteria-positive FM with > 90% accuracy. We used levels of the PSD scale to test whether symptom levels in primary FM (PFM) and secondary FM (SFM) were the same and whether symptoms were equivalent in persons not meeting FM crit...
Article
Background: Fibromyalgia (FM) is a clinically well-defined chronic condition of unknown aetiology characterised by chronic widespread pain that often co-exists with sleep problems and fatigue. People often report high disability levels and poor health-related quality of life (HRQoL). Drug therapy focuses on reducing key symptoms and disability, an...
Article
Specific human leukocyte antigen (HLA)-DRB1 alleles encode a "shared epitope" (SE) associated with rheumatoid arthritis (RA), especially more severe cyclic-citrullinated peptide antibody-positive (anti-CCP+) RA. Associations of SE alleles (0, 1 or 2) with total and cardiovascular disease (CVD) mortality and incident coronary heart disease (CHD), CV...

Despite weak to nonexistent evidence regarding the causal association of trauma and fibromyalgia (FM), literature and court testimony continue to point out the association as if it were a strong and true association. The only data that appear unequivocally to support the notion that trauma causes FM are case reports, cases series, and studies that...
Article
Rheumatoid arthritis (RA) patients have an increased risk of cardiovascular disease (CVD) and mortality. We measured anti-cyclic citrullinated peptide (anti-CCP) antibody levels and determined use of disease-modifying antirheumatic drugs (DMARDs) among women in the Women's Health Initiative (WHI). Using these data, we undertook this study to assess...
Article
Second-generation assays for anti-cyclic citrullinated peptide (anti-CCP), a highly sensitive and specific marker for rheumatoid arthritis (RA), have redefined the epidemiology of RA. In the Women's Health Initiative (WHI) RA study (2009-2011), we evaluated the prevalence of anti-CCP positivity among 15,691 (10.2% of 161,808) WHI participants aged...

Fibromyalgia is a common but contested illness. Its definition and content have changed repeatedly in the 110 years of its existence. The most important change was the requirement for multiple tender points and extensive pain that arose in the 1980s, features that were not required previously. By 2010, a second shift occurred that excluded tender p...
Article
Background and Purpose: Carotid artery plaque progression has been associated with significant cerebrovascular morbidity and mortality. Even though, lifestyle modifications are the cornerstone of the management of atherosclerotic disease, the long term effects of a healthy diet and regular exercise on the atherosclerotic burden of carotid arteries...
