RESUMEN

Colorectal cancer (CRC) is the third most common cancer and third leading cause of cancer-related death among African Americans in the United States. However, when detected early, CRC is treatable and survival rates are high. CRC health disparities for African Americans compared with other groups may be due in part to lower screening adherence and later stage diagnosis. The objective of this research phase was to test predictors of ever having received CRC screening (i.e., self-report of lifetime receipt of CRC screening) using survey measures in the domains of healthcare communication, trust in doctors, CRC perceived susceptibility, CRC worry, negative cancer beliefs, CRC screening self-efficacy, and cultural constructs for CRC screening in a sample of African American community health center patients. The study recruited 115 African American patients between the ages of 45 to 64 years old from community health centers in north Florida to complete the baseline survey. Our results show significant differences in CRC screening history by age, marital status, level of mistrust of healthcare providers, and level of empowerment toward cancer screening. To increase CRC screening in this population, the study findings suggest development of intervention programs that focus on priority populations of younger, unmarried African Americans, especially given the current trend of early onset CRC. Moreover, survival rates are lower for unmarried and younger African Americans relative to older and married individuals. Such interventions should also aim to increase trust in healthcare providers and increase empowerment for CRC screening decision making to increase screening participation.

RESUMEN

Colorectal cancer (CRC) is the third most diagnosed cancer in the USA, and African Americans experience disproportionate CRC diagnosis and mortality. Early detection could reduce CRC incidence and mortality, and reduce CRC health disparities, which may be due in part to lower screening adherence and later stage diagnosis among African Americans compared to whites. Culturally tailored interventions to increase access to and uptake of CRC stool-based tests are one effective strategy to increase benefits of screening among African Americans. The objectives of this study were to obtain feedback from African Americans on CRC educational materials being developed for a subsequent behavioral clinical trial and explore participants' knowledge, attitudes, and beliefs about CRC and CRC screening. Seven focus groups were conducted between February and November 2020. Participants were African Americans recruited through community contacts. Four focus groups were held in-person and three were conducted virtually due to Covid-19 restrictions. Participants ranked CRC educational text messages and provided feedback on a culturally tailored educational brochure. A focus group guide with scripted probes was used to elicit discussion and transcripts were analyzed using traditional content analysis. Forty-two African Americans participated. Four themes were identified from focus group discussions: (1) knowledge, attitudes, and beliefs on CRC and CRC screening; (2) reliable sources of cancer education information; (3) cultural factors affecting perspectives on health; and (4) community insights into cancer education. Participant input on the brochure was incorporated in content creation. Engaging African American community members to qualitatively examine cancer prevention has value in improving implementation strategy and planning for behavioral clinical trials.

RESUMEN

BACKGROUND: Epidemic projections and public health policies addressing Coronavirus disease (COVID)-19 have been implemented without data reporting on the seroconversion of the population since scalable antibody testing has only recently become available. METHODS: We measured the percentage of severe acute respiratory syndrome- Coronavirus-2 (SARS-CoV-2) seropositive individuals from 2008 blood donors drawn in the state of Rhode Island (RI). We utilized multiple antibody testing platforms, including lateral flow immunoassays (LFAs), enzyme-linked immunosorbent assays (ELISAs) and high throughput serological assays (HTSAs). To estimate seroprevalence, we utilized the Bayesian statistical method to adjust for sensitivity and specificity of the commercial tests used. RESULTS: We report than an estimated seropositive rate of RI blood donors of approximately 0.6% existed in April-May of 2020. Daily new case rates peaked in RI in late April 2020. We found HTSAs and LFAs were positively correlated with ELISA assays to detect antibodies specific to SARS-CoV-2 in blood donors. CONCLUSIONS: These data imply that seroconversion, and thus infection, is likely not widespread within this population. We conclude that IgG LFAs and HTSAs are suitable to conduct seroprevalence assays in random populations. More studies will be needed using validated serological tests to improve the precision and report the kinetic progression of seroprevalence estimates.

RESUMEN

BACKGROUND: Colorectal cancer (CRC) is the second most deadly cancer affecting US adults and is also one of the most treatable cancers when detected at an earlier clinical stage of disease through screening. CRC health disparities experienced by African Americans are due in part to the later stage of diagnosis, suggesting the importance of improving African Americans' CRC screening participation. The national Screen to Save (S2S) initiative employs a community health educator to deliver CRC screening education which can be tailored for specific populations, and such approaches have increased CRC screening rates in disadvantaged and racial/ethnic minority populations. METHODS/DESIGN: In this trial emphasizing stool-based CRC screening, focus groups informed the development of an adapted S2S video and brochure tailored for African Americans and identified preferred motivational text messages for a multicomponent community health advisor (CHA) intervention. A CHA hired from the community was trained to deliver a 6-week CRC educational intervention consisting of an initial face-to-face meeting followed by 5 weeks of calls and texts. Interested eligible persons are enrolled primarily through recruitment by two partnering community health centers (CHCs) and secondarily through various outreach channels and, after consenting and completing a baseline survey, are randomly assigned to one of two study arms. The CHCs are blinded to study arm assignment. Intervention arm participants receive the brochure and CHA intervention while participants assigned to the control group receive only the brochure. All participants receive a stool-based CRC screening test from their health center, and the primary outcome is the completion of the screening test at 12 months. Secondary objectives are to estimate the effect of the intervention on mediating factors, explore the effect of moderating factors, and perform a cost-effectiveness analysis of the CHA intervention. DISCUSSION: The TUNE-UP study will enhance understanding about CRC screening in African Americans obtaining primary health care through CHCs and is one of the very few studies to examine a CHA intervention in this context. A better understanding of the mechanisms by which the intervention affects patient beliefs and behaviors will help focus future research while the exploratory cost-effectiveness analysis will inform CHCs' decision-making about implementing a CHA program to increase screening and reduce cancer health disparities.

RESUMEN

Community health advisor (CHA) interventions increase colorectal cancer (CRC) screening rates. African Americans experience CRC disparities in incidence and mortality rates compared to whites in the US. Focus groups and learner verification were used to adapt National Cancer Institute CRC screening educational materials for delivery by a CHA to African American community health center patients. Such academic-community collaboration improves adoption of evidence-based interventions. This short article describes the adaptation of an evidence-based cancer education intervention for implementation in an African American community.
