TL;DR: The parent–child pairs revealed a trend toward increasing exogamy over time; the presence in the cohort of individuals endorsing multiple race/ethnicity categories creates interesting challenges and future opportunities for genetic epidemiologic studies.
Journal ArticleDOI

TL;DR: The high quality and large scale of genotype data created on this cohort, in conjunction with comprehensive longitudinal data from the KP electronic health records of participants, will enable a broad range of highly powered genome-wide association studies on a diversity of traits and conditions.
Journal ArticleDOI

TL;DR: This study establishes reliable assay and analysis methodologies for measurement of TL in large, population-based human studies in the GERA cohort, the largest currently available such resource, linked to comprehensive electronic health and genotype data for analysis.
Journal ArticleDOI
Effects of Psychological Intervention on Panic Attack Patients in the Emergency Department
TL;DR: The contact condition reduced ED use after the initial visit to the ED, although all three groups had more visits to the psychiatry department and to all nonpsychiatric departments, an important therapeutic and economic finding.
Journal ArticleDOI
The Depression-Arkansas scale: A validation study of a new brief depression scale in an HMO
TL;DR: The D-ARK was calibrated against the BDI-2 and GDS, providing familiar severity category cutpoints with the new instrument, and further data is yielded supporting the reliability, validity, and practical utility of the D-Ark.
