    Background: Human Papillomavirus associated oropharyngeal cancers have been on the rise in the past three decades. Dentists are uniquely positioned to discuss vaccination programs with their patients. The goal of this project was to assess the readiness of dentists in the state of Indiana in being able to administer vaccines. Methods: An 18-question online survey was sent to licensed dentists in the state of Indiana. Mantel-Haenszel chi-square tests, followed by multivariable analyses using ordinal logistic regression were conducted to assess providers' comfort levels and willingness to administer vaccines in both children and adults, by provider characteristics (practice type, location, and years in practice). Results: A total of 569 completed surveys were included for data analyses. Most dentists (58%) responded positively when asked if they would consider offering vaccinations in their office, if allowed by state legislation. In general, dentists working in academic settings and federally qualified health centers were more agreeable to offering vaccination in their practice. The level of agreement with "Dentists should be allowed to administer HPV, Influenza, Hep A and COVID 19 vaccines" for both children and adults decreased with increased years of practice. More than half of the respondents (55%) agreed that dental providers were competent to administer vaccines and needed no further training. Conclusion: The study results suggest the willingness of dentists in the state of Indiana to offer vaccinations in their practices, if allowed by legislation. Practical implications: Dental providers can be a unique resource to add to workforce for improving vaccination efforts.

    Health care providers’ perceptions of use and influence of clinical decision support reminders: qualitative study following a randomized trial to improve HPV vaccination rates
    (BMC, 2017-08-10) Dixon, Brian E.; Kasting, Monica L.; Wilson, Shannon; Kulkarni, Amit; Zimet, Gregory D.; Downs, Stephen M.; Epidemiology, School of Public Health
    Background Human Papillomavirus (HPV) leads to serious health issues and remains the most common sexually transmitted infection. Despite availability of effective vaccines, HPV vaccination rates are suboptimal. Furthermore, providers recommend the HPV vaccine less than half the time for eligible patients. Prior informatics research has demonstrated the effectiveness of computer-based clinical decision support (CDS) in changing provider behavior, especially in the area of preventative services. Methods Following a randomized clinical trial to test the effect of a CDS intervention on HPV vaccination rates, we conducted semi-structured interviews with health care providers to understand whether they noticed the CDS reminders and why providers did or did not respond to the prompts. Eighteen providers, a mix of medical doctors and nurse practitioners, were interviewed from five publicly-funded, urban health clinics. Interview data were qualitatively analyzed by two independent researchers using inductive content analysis. Results While most providers recalled seeing the CDS reminders, few of them perceived the intervention as effective in changing their behavior. Providers stated many reasons for why they did not perceive a change in their behavior, yet the results of the trial showed HPV vaccination rates increased as a result of the intervention. Conclusions CDS reminders may be effective at changing provider behavior even if providers perceive them to be of little use.

    Levels of the E2 interacting protein TopBP1 modulate papillomavirus maintenance stage replication
    (Elsevier, 2015-04) Kanginakudru, Sriramana; DeSmet, Marsha; Thomas, Yanique; Morgan, Iain M.; Androphy, Elliot J.; Department of Dermatology, IU School of Medicine
    The evolutionarily conserved DNA topoisomerase II beta-binding protein 1 (TopBP1) functions in DNA replication, DNA damage response, and cell survival. We analyzed the role of TopBP1 in human and bovine papillomavirus genome replication. Consistent with prior reports, TopBP1 co-localized in discrete nuclear foci and was in complex with papillomavirus E2 protein. Similar to E2, TopBP1 is recruited to the region of the viral origin of replication during G1/S and early S phase. TopBP1 knockdown increased, while over-expression decreased transient virus replication, without affecting cell cycle. Similarly, using cell lines harboring HPV-16 or HPV-31 genome, TopBP1 knockdown increased while over-expression reduced viral copy number relative to genomic DNA. We propose a model in which TopBP1 serves dual roles in viral replication: it is essential for initiation of replication yet it restricts viral copy number.
