Abstract
Cancer patients are at an increased risk of morbidity and mortality from SARS-CoV-2 infection and have a decreased immune response to vaccination. We conducted a study measuring both the neutralizing and total antibodies in cancer patients following a third dose of the mRNA-1273 COVID-19 vaccine. Immune responses were measured with an enzyme-linked immunosorbent assay (ELISA) and neutralization assays. Kruskal-Wallis tests were used to evaluate the association between patient characteristics and neutralization geometric mean titers (GMTs), and paired t-tests were used to compare the GMTs between different timepoints. Spearman correlation coefficients were calculated to determine the correlation between total antibody and neutralization GMTs. Among 238 adults diagnosed with cancer, a third dose of mRNA-1273 resulted in a 37-fold increase in neutralization GMT 28 days post-vaccination and maintained a 14.6-fold increase at 6 months. Patients with solid tumors or lymphoid cancer had the highest and lowest neutralization GMTs, respectively, at both 28 days and 6 months post-dose 3. While total antibody GMTs in lymphoid patients continued to increase, other cancer types showed decreases in titers between 28 days and 6 months post-dose 3. A strong correlation (p < 0.001) was found between total antibody and neutralization GMTs. The third dose of mRNA-1273 was able to elicit a robust neutralizing antibody response in cancer patients, which remained for 6 months after administration. Lymphoid cancer patients can benefit most from this third dose, as it was shown to continue to increase total antibody GMTs 6 months after vaccination.

Abstract
Background The role of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) neutralizing antibody response from natural infection and vaccination, and the potential determinants of this response are poorly understood. Characterizing this antibody response and the factors associated with neutralization can help inform future prevention efforts and improve clinical outcomes in those infected. Objectives The goals of this study were to prospectively evaluate SARS-CoV-2 antibody levels and the neutralizing antibody responses among naturally infected adults and to determine demographic and behavioral factors independently associated with these responses. Methods Serum was collected from seropositive individuals at baseline, four-weeks, and three-months following their first study visit to be evaluated for antibody levels. Detection of neutralizing antibodies was performed at baseline. Participant demographic and behavioral information was collected via web questionnaire prior to their first visit. Results At baseline, higher antibody levels were associated with better neutralization capacity, with 83% of participants having detectable neutralizing antibodies. We found an age-dependent effect on antibody level and neutralization capacity with participants over 65 years having significantly higher levels. Ethnicity, heart disease, autoimmune disease, and COVID symptoms were associated with higher antibody levels, but not with increased neutralization capacity. Work environment during the pandemic correlated with increased neutralization capacity, while kidney or liver disease and traveling out of state after February 2020 correlated with decreased neutralization capacity, however neither correlated with antibody levels. Conclusions Our data show that natural infection by SARS-CoV-2 can induce a humoral response reflected by high antibody levels and neutralization capacity.

Abstract
We evaluated the acceptability of a patient activation toolkit for hepatitis C virus (HCV) testing amidst universal adult guidelines. We developed a patient-facing toolkit that included a letter to the patient from their healthcare provider, HCV factsheet, and question prompt list, which contained questions for their provider about HCV infection and testing. We conducted qualitative interviews with patients ages 18-78 (n = 17), using a semi-structured interview guide based on learner verification. We assessed attraction, comprehension, cultural-linguistic acceptability, self-efficacy, and persuasiveness of toolkit materials using direct content analysis. Participants reported materials were attractive, offering suggestions to improve readability. They reported some understanding of materials but requested use of less medical jargon, particularly for the factsheet. Participants discussed cultural acceptability and suggested ways to improve language inclusiveness and comfort with content, given stigma surrounding HCV risk factors. Participants reported that including a letter, factsheet, and QPL improved the persuasiveness of materials, and they conveyed their motivation to be tested for HCV. Results indicate preliminary acceptability for use of the patient activation toolkit, which will be refined based on participants' recommendations. Overall, this patient activation toolkit holds promise for increasing HCV testing rates.

Abstract
Estimating the actual extent of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is challenging because virus test positivity data undercount the actual number and proportion of persons infected. SARS-CoV-2 seroprevalence is a marker of past SARS-CoV-2 infection regardless of presence or severity of symptoms and therefore is a robust biomarker of infection period prevalence. We estimated SARS-CoV-2 seroprevalence among residents of Hillsborough County, Florida, USA, to determine factors independently associated with SARS-CoV-2 antibody status overall and among asymptomatic antibody-positive persons. Among 867 participants, SARS-CoV-2 period prevalence (October 2020–March 2021) was 19.5% (asymptomatic seroprevalence was 8%). Seroprevalence was 2-fold higher than reported SARS-CoV-2 virus test positivity. Factors related to social distancing (e.g., essential worker status, not practicing social distancing, contact with a virus-positive person, and length of contact exposure time) were consistently associated with seroprevalence but did not differ by time since suspected or known infection (<6 months vs. >6 months).

Abstract
Many U.S. residents infected with hepatitis C virus (HCV) are baby boomers (born 1945-1965), who remain undiagnosed. Past CDC and USPSTF guidelines recommended one-time HCV testing for all baby boomers, with newer guidelines recommending universal screening for all adults. This retrospective cohort study examined electronic medical records for patient visits from 2015 to 2017 within the OneFlorida Data Trust and University of South Florida Health system. We assessed percentages of HCV tests ordered and completed across four age groups (those born before 1945, 1945-1965, 1966-1985, and after 1985). In 2019, we used logistic regression to examine factors associated with HCV test ordering and completion among baby boomers, including age, race, sex, number of primary care visits, HIV status, hepatitis diagnosis, and liver cancer history. All age groups had low rates of HCV test orders. 4.4% of baby boomers had a test ordered in 2015, and 6.7% in 2016. Of those, 94.5% and 89.7% completed testing, respectively. All other races/ethnicities had lower likelihood of testing completion than Whites (Blacks (aOR 0.82, 95%, CI 0.75-0.91); Asians (0.69, 0.52-0.92); Hispanics (0.29, 0.26-0.32)), although test orders were higher for Asians (1.48, 1.37-1.61) and Blacks (1.78, 1.73-1.82). Tests ordered (11.42, 10.94-11.92) and completed (2.25, 1.94-2.60) were more likely among those with hepatitis history. Test orders were more likely for HIV-positive patients (3.68, 3.45-3.93), but completion was less likely (0.67, 0.57-0.78). Interventions are needed to increase testing rates so that HCV infections are treated early, mitigating HCV-related morbidity and mortality, especially related to liver cancer.

Abstract
BACKGROUND Liver cancer rates are rising and hepatitis C virus (HCV) is the primary cause. The CDC recommends a one-time HCV screening for all persons born 1945-1965 (baby boomers). However, 14% of baby boomers have been screened. Few studies have examined primary care providers' (PCP) perspectives on barriers to HCV screening. This study examines current HCV screening practices, knowledge, barriers, and facilitators to HCV screening recommendation for baby boomers among PCPs. METHODS We conducted a mixed methods pilot study of PCPs. Quantitative: We surveyed PCPs from 3 large academic health systems assessing screening practices, knowledge (range:0-9), self-efficacy to identify and treat HCV (range:0-32), and barriers (range:0-10). Qualitative: We conducted interviews assessing patient, provider, and clinic-level barriers to HCV screening for baby boomers in primary care. Interviews were audio recorded, transcribed, and analyzed with content analysis. RESULTS The study sample consisted of 31 PCPs (22 survey participants and nine interview participants). All PCPs were aware of the birth cohort screening recommendation and survey participants reported high HCV testing recommendation, but qualitative interviews indicated other priorities may supersede recommending HCV testing. Provider knowledge of viral transmission was high, but lower for infection prevalence. While survey participants reported very few barriers to HCV screening in primary care, interview participants provided a more nuanced description of barriers such as lack of time. CONCLUSIONS There is a need for provider education on both HCV treatment as well as how to effectively recommend HCV screening for their patients. As HCV screening guidelines continue to expand to a larger segment of the primary care population, it is important to understand ways to improve HCV screening in primary care.

Abstract
BACKGROUND Baby boomers are at increased risk for hepatitis C virus (HCV) infection and related cancer; therefore, one-time HCV screening is recommended. METHODS To assess prevalence of, and factors associated with providers ordering HCV screening, we examined a retrospective cohort of electronic medical records for patient visits from 01 August 2015 until 31 July 2017 in a large health system. HCV screening ordered was examined by patient age, gender, race/ethnicity, provider specialty, and number of clinical visits, stratified by birth cohort: born ≤1945, 1945-1965 (baby boomers), 1966-1985, and ≥1985. Multivariable regression identified factors independently associated with HCV screening ordered among average risk baby boomers. RESULTS A total of 65 114 patients ages ≥18 years were evaluated. Among baby boomers HCV screening test order increased threefold between the two study years (4.0%-12.9%). Odds of screening test ordered were significantly higher for non-Hispanic Blacks (multivariable adjusted odds ratio [aOR]=1.36; 95% CI = 1.19-1.55), males (aOR = 1.44; 95% CI = 1.33-1.57), and having a clinic visit with a primary care provider alone or with specialty care (aOR = 3.25-4.16). Medicare (aOR = 0.89; 95% CI = 0.80-0.99), Medicaid (aOR 0.89; 95% CI 0.80-0.99), and an unknown provider type (aOR = 0.16; 95% CI = 0.08-0.33), were associated with lower odds of screening tests ordered. CONCLUSIONS While the proportion of baby boomers with an HCV screening test ordered increased during the study, the rate of screening remains far below national goals. Data from this study indicate that providers are not ordering HCV screening universally for all of their baby boomer patients. Continued efforts to increase HCV screening are needed to reduce the incidence of HCV-related morbidity and mortality.
