  • Fine particulate matter-sudden death association modified by ventricular hypertrophy and inflammation

    Open AccessKristen M Rappazzo, Nicole M Egerstrom et al.ARTICLEFrontiers in Public Health2024

    Background Sudden death accounts for approximately 10% of deaths among working-age adults and is associated with poor air quality.

OBJECTIVE: We estimated YLL and productivity loss from SUD in working-age adults and compared it with the leading causes of death in the United States. METHODS: We screened all out of hospital …

    Emily S Brouwer, Sonia Napravnik et al.ARTICLEMedical Care2015References: 1

    BACKGROUND: In nonexperimental comparative effectiveness research using health care databases, outcome measurements must be validated to evaluate and potentially adjust for misclassification bias. We aimed to validate claims-based myocardial infarction (MI) algorithms in a Medicaid population using an HIV clinical cohort as the gold standard. METHODS: Medicaid administrative data were obtained for the years 2002-2008 and linked to the UNC CFAR HI…

METHODS: This was a cross-sectional study of 107 physicians who completed a validated survey of attitudes and beliefs about hyperlipidemia and provided treatment histo…
