People with rheumatoid arthritis (RA) who experienced disease flares often showed changes in heart rate and physical activity captured by popular wearable devices 4 weeks before they became clinically apparent, a small study indicated.

Juvenile dermatomyositis (JDM) is typically recognized for its striking skin rashes, vasculopathy, and muscle inflammation. Less visible, but equally significant, is lung involvement. Interstitial lung disease (ILD) is increasingly acknowledged as a critical driver of morbidity and mortality in this condition. While myositis itself can be debilitating, it is pulmonary disease that often dictates long-term outcomes.

An exercise and diet intervention study showed that while exercise improved hip pain, adding a weight loss diet to exercise did not change hip pain but improve most secondary outcomes.
