Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study

open access: yesArthritis Care &Research, EarlyView.
Objective Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...

Relative content of Be stars in young open star clusters

Astronomy Letters, 2012
Based on high- and medium-resolution spectra, we analyze the population of Be stars in eight young open star clusters. We have found a clear dependence of the relative content of early-type (B0-B3) Be stars on the cluster age. The relative concentration of Be stars of spectral types B0–B3 gradually increases with cluster age, reaching its maximum value

Be Stars in Open Stellar Clusters

Astrophysics, 2017
The current status of the problem of anomalous increases in the relative number of Be stars in young open stellar clusters is summarized in this article. The relative content of Be stars is shown to increase with the age of the clusters and reaches a maximum for stars in spectral classes B0-B3 when the age of the clusters is 12-20 Myr. In some clusters
