Pulmonary arterial hypertension (PAH) is a life-threatening complication of connective tissue diseases (CTD). Our aim was to compare the diagnostic utility of noninvasive imaging modalities, i.e., magnetic resonance imaging (MRI), computed tomography (CT), and echocardiography, in evaluation of these patients. ⋯ In patients with CTD and suspected PAH, cardiac MRI and echocardiography have greater diagnostic utility than CT in the assessment of patients with suspected PAH, and MRI has prognostic value.

A prospective observational study of mycophenolate mofetil (MMF) treatment in patients with diffuse progressive cutaneous systemic sclerosis (SSc) of recent onset. ⋯ Patients with diffuse progressive cutaneous SSc of recent onset treated with MMF experienced marked improvement in skin involvement and stabilization of pulmonary function. Skin biopsies from 3 patients demonstrated histopathological improvement and decreased expression of fibrosis-related genes.

Rheumatoid arthritis (RA) is a common debilitating autoimmune disease, with unmet need for knowledge among patients and the general population. YouTube is a popular, consumer-generated, video-sharing website, which can be a source of information on RA. We investigated the quality of information on RA on YouTube and analyzed audience interaction. ⋯ YouTube is a source of information on RA, of variable quality, with wide viewership and potential to influence patients' knowledge and behavior. Physicians and professional organizations should be aware of and embrace this evolving technology to raise awareness about RA, and empower patients to discriminate useful from misleading information.

To determine whether levels of plasma-soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) are elevated in patients with rheumatoid arthritis (RA) and whether levels are correlated with disease activity and other variables. ⋯ Patients with RA had higher plasma sTREM-1 levels than healthy controls, and plasma sTREM-1 levels were correlated with disease activity measures, suggesting that plasma sTREM-1 could play a role in the inflammatory process associated with TNF-α, and that it may be a useful disease activity marker in RA.
