Circulating Fibrocytes as Biomarker of Prognosis in Hermansky-Pudlak Syndrome.
The rate of progression of most interstitial lung diseases (ILD) is unpredictable. Fibrocytes are circulating bone marrow-derived cells that have been implicated in the pathogenesis of lung fibrosis. Hermansky-Pudlak syndrome (HPS), a genetic cause of ILD in early adulthood, allows for study of biomarkers of ILD in a homogeneous population at near-certain risk of developing fibrotic lung disease. ⋯ CXCR4(+) fibrocyte concentration may be useful as a biomarker for outcome of ILD in subjects with HPS.

Practice GuidelineAn Official American Thoracic Society Clinical Practice Guideline: The Diagnosis of Intensive Care Unit-acquired Weakness in Adults.
Profound muscle weakness during and after critical illness is termed intensive care unit-acquired weakness (ICUAW). ⋯ Research that identifies treatments that benefit patients with ICUAW is necessary to determine whether the benefits of diagnostic testing for ICUAW outweigh its burdens.

Assessing Pulmonary Hypertensive Vascular Disease in Childhood: Data from the Spanish Registry.
There is a lack of knowledge regarding the epidemiology, clinical characterization, and survival in pediatric pulmonary hypertension. ⋯ In moderate to severe pediatric pulmonary hypertension, the prognosis is better in pulmonary arterial hypertension than in other Nice categories. In pediatric pulmonary hypertension age at diagnosis younger than 2 years is a risk factor for mortality, in addition to the previously established risk factors.
