    Critical Role of microRNA-21 in the Pathogenesis of Liver Diseases
    (Frontiers Media, 2020-01-31) Zhang, Ting; Yang, Zhihong; Kusumanchi, Praveen; Han, Sen; Liangpunsakul, Suthat; Medicine, School of Medicine
    MicroRNAs are small non-coding RNAs that range in length from 18 to 24 nucleotides. As one of the most extensively studied microRNAs, microRNA-21 (miR-21) is highly expressed in many mammalian cell types. It regulates multiple biological functions such as proliferation, differentiation, migration, and apoptosis. In this review, we summarized the mechanism of miR-21 in the pathogenesis of various liver diseases. While it is clear that miR-21 plays an important role in different types of liver diseases, its use as a diagnostic marker for specific liver disease or its therapeutic implication are not ready for prime time due to significant variability and heterogeneity in the expression of miR-21 in different types of liver diseases depending on the studies. Additional studies to further define miR-21 functions and its mechanism in association with each type of chronic liver diseases are needed before we can translate the bedside observations into clinical settings.

    Hepatitis C Virus Screening: Factors Associated With Test Completion in a Large Academic Health Care System
    (Sage, 2022) Kasting, Monica L.; Christy, Shannon M.; Reich, Richard R.; Rathwell, Julie A.; Roetzheim, Richard G.; Vadaparampil, Susan T.; Giuliano, Anna R.; Medicine, School of Medicine
    Objectives: In 2012, onetime hepatitis C virus (HCV) screening was recommended for all baby boomers (people born during 1945-1965) in the United States, but only 4.0%-12.9% of baby boomers have ever had a screening ordered by a health care provider. This study examined the HCV screening prevalence among adult patients in a large academic health care system and assessed factors associated with the completion of screening when ordered for baby boomers. Methods: We defined HCV screening completion as the completion of an HCV antibody test when it was ordered. We used electronic health records to examine HCV screening completion rates among adults (N = 106 630) from August 1, 2015, through July 31, 2020, by birth cohort. Among baby boomers whose health care provider ordered HCV screening, we examined frequency and percentages of HCV screening completion by sociodemographic and clinical characteristics. We conducted univariate and multivariable logistic regression analyses to assess factors associated with HCV screening completion among baby boomers. Results: During the study period, 73.0% of baby boomers completed HCV screening when it was ordered. HCV completion did not differ by sex or race and ethnicity among baby boomers. Baby boomers with Medicare supplemental health insurance compared with commercial health insurance (adjusted odds ratio [aOR] = 1.87) and those seeing only advanced practice professionals compared with specialty care physicians (aOR = 2.24) were more likely to complete HCV screening when it was ordered. Conclusions: Noncompletion of HCV screening is one of many barriers along the HCV treatment continuum. Our findings suggest a need for interventions targeting systems, health care providers, and patients to increase HCV screening rates in the United States.
