Contralateral knee effect on self-reported knee-specific function and global functional assessment: data from the Osteoarthritis Initiative.
To analyze the effect of contralateral knee pain on sensitivity of patient-reported outcomes and objectively measured functional performance tests in subjects with knee osteoarthritis (OA). ⋯ The WOMAC physical function score, although knee specific, is impacted by the contralateral knee pain status. The repeated chair stand test appears to be the most sensitive assessment in differentiation between groups with different status of knee pain.

Interactions between patients, providers, and health systems and technical quality of care.
Prior studies have established disparities by race/ethnicity and socioeconomic status (SES) in the kind, quantity, and technical quality of systemic lupus erythematosus (SLE) care and outcomes. In this study we evaluate whether disparities exist in assessments of interactions with health care providers and health plans and whether such interactions affect the technical quality of SLE care. ⋯ Ratings in the lowest quartile on all dimensions of interactions with providers and the health care system were associated with lower technical quality of care, potentially resulting in poorer SLE outcomes.

What triggers an episode of acute low back pain? A case-crossover study.
To investigate a range of transient risk factors for an episode of sudden-onset, acute low back pain (LBP). ⋯ Transient exposure to a number of modifiable physical and psychosocial triggers substantially increases risk for a new episode of LBP. Triggers previously evaluated in occupational injury studies, but never in LBP, have been shown to significantly increase risk. These results aid our understanding of the causes of LBP and can inform the development of new prevention approaches.

Sleep disturbance in osteoarthritis: linkages with pain, disability, and depressive symptoms.
It is known that osteoarthritis (OA) increases the risk of sleep disturbance, and that both pain and sleep problems may trigger functional disability and depression. However, studies examining all 4 variables simultaneously are rare. The aim of this study was to examine cross-sectional and longitudinal associations of self-reported sleep disturbance with OA-related pain and disability and depressive symptoms. ⋯ These data confirm known cross-sectional relationships between sleep disturbance and pain and depression and provide new insights regarding longitudinal associations among those variables. Depression appears to play a strong role in the sleep-pain linkage, particularly when pain is severe. The unique predictive role of sleep in the progression of disability requires further study but may be an important point of intervention to prevent OA-related functional decline among persons whose sleep is disrupted by OA-related pain.

Diabetes is associated with increased hand pain in erosive hand osteoarthritis: data from a population-based study.
To explore factors related to hand pain in persons with radiographic hand osteoarthritis (OA). ⋯ Structural and inflammatory OA changes as well as demographic factors, psychosocial factors, and diabetes mellitus were associated with pain in hand OA. The strong association between diabetes mellitus and pain in erosive hand OA should be further explored.
