Multicenter Study
Actigraphic Sleep Patterns and Hypertension in the Hispanic Community Health Study/Study of Latinos.
The aim of this study was to evaluate the association between actigraphy-based measures of sleep and prevalent hypertension in a sample of US Latinos. ⋯ Independent of sleep-disordered breathing, we observed associations between reduced sleep continuity and daytime napping, but not short sleep duration, and prevalent hypertension.

Predictors of Prolonged Hospitalizations in Pediatric Complicated Pneumonia.
Pediatric community-acquired complicated pneumonia (PCACP) is characterized by a prolonged clinical course, but this may be highly variable. ⋯ In children, pleural fluid LDH and glucose levels are useful parameters for assessing the severity of PCACP. The model developed in this study accurately predicts patients who will have prolonged hospitalization.

Multicenter Study Comparative Study
Triggering Receptor Expressed on Myeloid Cells-2 (TREM-2) expression tracks with M2-like macrophage activity and disease severity in COPD.
Cell and animal models show a key role for Triggering Receptor Expressed on Myeloid Cells (TREM)-2 in chronic airway disease after viral infection, but comparable evidence in humans still needs to be established. ⋯ TREM-2 expression is increased in lung macrophages in COPD, particularly in comparison with TREM-1. Therefore, TREM-2 levels and the ratio of TREM-2/TREM-1 signifies M2 activation in COPD lung tissues and may help to guide therapeutics directed against the type 2 immune response in patients with this disease.

Pulmonary arterial hypertension associated with systemic lupus: results from the French Pulmonary Hypertension Registry.
Pulmonary arterial hypertension (PAH) is a rare complication of systemic lupus erythematosus (SLE). ⋯ Patients with SLE-PAH have an overall 5-year survival rate of 83.9% after the PAH diagnosis. Anti-SSA/SSB antibodies may be a risk factor for PAH, and the presence of anti-U1-RNP antibodies appears to be a protective factor regarding survival.
