While recent standards provide for structured entry of family history, many clinicians record family history data in text. The authors sought to characterize family history information within clinical documents to assess the adequacy of existing models(More)

While researchers have focused upon this extensible classification scheme to understand and summarize structured data, few studies have analyzed the use of associated text. Two years of client records were accessed from two diverse sites utilizing the(More)
To characterize susceptibility to HIV infection, we phenotyped infected tonsillar T cells by single-cell mass cytometry and created comprehensive maps to identify which subsets of CD4+ T cells support HIV fusion and productive infection. By comparing HIV-fused and HIV-infected cells through dimensionality reduction, clustering, and statistical approaches to(More)
