Abstract Introduction: In an effort to ensure an all-inclusive initiative that would close the disparity gap among the immigrant communities in Florida, we developed a pilot project under the Inclusive Cancer Care Research Equity (iCCaRE) for Black Men Consortium with generous support from the Mayo Clinic Comprehensive Cancer Center (MCCCC). The objective is to train cancer advocates to engage their communities and develop and implement cancer prevention and screening navigation programs. The central hypothesis for this program is that community-driven cancer advocacy will significantly improve cancer awareness, knowledge, prevention, risk reduction, screening uptake, and early detection among Black immigrants. Methods: We collaborated with immigrant communities’ leaders to brainstorm on the current state of healthcare access and disparities experienced by Black immigrants and to set program and research priorities through listening sessions. Cancer advocates were trained to engage their communities to (1) develop and implement cancer risk reduction and education programs using train-the-trainer approach, (2) mobilize the resources within the community for cancer health promotion, prevention, and screening strategies, (3) partner with key stakeholders to accomplish targeted objectives; (4) raise funds to support advocacy activities; and (5) develop and successfully organize community-centered programs. Results: We are currently working with 10 Black immigrant organizations, including immigrant churches across different ethnicities, including Nigeria, Ghana, Cameroon, Liberia, South Africa, Haiti, Jamaica, and across different cities in the United States. Eighteen community cancer advocates, including breast and prostate cancer survivors, caregivers, and community influencers, were trained to engage the immigrant communities in cancer risk reduction and research in Florida using multiple channels, including in-person community programs and online engagement approaches. We have engaged 720 immigrants in cancer risk reduction education and the need to participate in research during advocate-led in-person community outreaches. We currently have 26 immigrants who have volunteered in the Mayo Clinic Community Research Registry. The program is ongoing, and we anticipate that more than 750 will be engaged, and 100 will volunteer to be registered in the Mayo Clinic Community Research Registry. Conclusion: Advocate-led advocacy in immigrant communities will provide evidence for compelling arguments about the feasibility and availability of the Black immigrant population for robust and sustainable research and program engagements to eliminate disparity and advance cancer health equity.

Abstract Introduction: In Sub-Saharan Africa (SSA), high cancer incidence is compounded by limited healthcare access and out-of-pocket costs. Additional factors like limited research funding, socioeconomic disparities, and cultural influences further affect cancer survivors' well-being. While some studies identify factors improving psychosocial well-being, there is a gap in understanding SSA-specific contextual and behavioral influences. This study addresses this gap through a scoping review of post-treatment cancer behavioral research, synthesizing current knowledge to inform interventions aimed at enhancing psychosocial support and improving health outcomes for survivors in the region. Methods: Guided by Arksey and O'Malley's 5-step framework, we conducted a scoping review to map cancer-focused behavioral research in Sub-Saharan Africa, aiming to inform policy and identify research gaps. Through comprehensive literature searches and eligibility criteria based on the PICOS framework, we identified relevant studies. Searches were executed from September-October 2023. Our search strategy encompassed multiple databases and supplementary methods to ensure thorough coverage. Screening, extraction, and analysis of the selected articles were conducted independently by at least two reviewers, using Microsoft Excel and Covidence and resolving discrepancies through discussion. Ultimately, seven articles met our inclusion criteria. Data were charted and summarized, covering demographics, study design, barriers, facilitators, cultural factors, support mechanisms, and recommendations. Results: Seven articles from four SSA countries were reviewed, with Nigeria contributing the most studies. The study articles, spanning from 1998 to 2023, used diverse methodologies and theoretical frameworks. The studies covered various cancer types and stages, highlighting significant psychological distress, financial toxicity, and post-traumatic growth among survivors. Cultural influences, including stigma and spiritual beliefs, were prominent. Barriers to care included financial constraints and limited access, while facilitators were social support and positive healthcare relationships. Effective support mechanisms like social and psychological interventions were crucial for enhancing survivors' well-being and promoting long-term follow-up care. Conclusion: This scoping review highlights the significant psychological, financial, and cultural challenges faced by cancer survivors in SSA. Addressing these challenges requires targeted interventions and policies that consider the unique contextual factors of SSA, aiming to enhance psychosocial support and improve overall health outcomes for cancer survivors. Future research should focus on comprehensive and culturally competent approaches to mitigate barriers and leverage facilitators, ultimately fostering a more supportive environment for cancer survivorship in the region.

Abstract Background: Nutritional and inflammatory factors collected in routine cancer labs, neutrophil percentage to albumin ratio (NPAR), neutrophil lymphocyte ratio (NLR), monocyte lymphocyte ratio (MLR), and platelet lymphocyte ratio (PLR), have been shown feasible in identification of patients at risk of increased treatment complications, decreased cognition, anxiety and depression, and increased mortality. These have proven sensitive to multiple cancer types and stages, though little is known about causal pathways. The Vitamin/Mineral and Inflammatory Correlations To Understand Chronic Stress in the U.S. (The VICTUS Study) sought to elucidate a relationship between diet and food insecurity within these panels. Methods: Using NHANES 2017/2018 surveys, adults > 18 years without renal or hepatic disorders, pregnancy, alcohol, or supplement use were included. NPAR, NLR, MLR, and PLR were categorized as quartiles and compared to demographic, food security, plasma micronutrient statuses [vitamins A, B9, C, D, E, calcium (Ca), ferritin (Fe), phosphorus (P), potassium (K), sodium (Na)], and smoking, activity level, and sun exposure, using chi-square and ANOVA. ANOVA models compared food security and poverty to NPAR, NLR, MLR, and PLR means. Results: From 3,317 participants, 50.2% were male, 54.3% non-Hispanic White, 33.7%, food insecure, 51.1% food stamp recipients, 27.7% smokers, with a mean age of 42.5 (SD 0.44), poverty to income ratio 2.79 (SD 0.08), CRP 3.90 (SD 0.18), NPAR 14.1 (SD 0.14), NLR 2.07 (SD 0.04), MLR 0.28 (SD 0.003), and PLR 118.7 (SD 1.61). CRP was found to be statistically significantly associated with all biomarker ratios (p < 0.018). Significant micronutrient biomarker-inflammatory biomarker associations were identified in Fe [NPAR, MLR, PLR (p < 0.001)], P [NPAR, NLR, MLR, PLR (p < 0.033)], C [NPAR, NLR (p < 0.008)], E [MLR, PLR (p < 0.016)], K [NPAR, NLR, MLR, PLR (p < 0.015)], Ca [NPAR, PLR (p < 0.04)], A [NPAR (p < 0.023)] and D [NLR (p < 0.035)]. Significant micronutrient intake-inflammatory biomarker associations were detected in vitamin A [NPAR, PLR (p < 0.013)], lycopene [NLR, PLR (p < 0.035)], and B12 [NLR, PLR (p < 0.031)]. Age [NPAR, NLR, MLR, PLR (p < 0.001)], gender [NPAR, MLR, PLR (p < 0.001)], ethnicity [NPAR, NLR, MLR (p < 0.006)], and sedentariness [MLR, PLR (p < 0.039)] were also associated with inflammatory markers. Poverty was significantly associated with NPAR, NLR, MLR, and CRP (p < 0.018). Food insecurity was significantly associated with NPAR (p < 0.001) and CRP (p < 0.001). Discussion: Food insecurity and poverty were significantly associated with NPAR, a ratio implicated in overall poorer cancer health outcomes. Multiple inadequate micronutrient intakes and plasma biomarkers were associated with inflammatory panels, though neither nutritional biomarker nor food insecurity statuses and their contributions to inflammatory processes are routinely surveilled within cancer disease and treatment.

Abstract Background: The need to increase understanding of prostate cancer (CaP) is ever increasing. Unfortunately, there is limited understanding of how CaP affects men of African ancestry (MAA) despite significant disparities in CaP prevention, diagnosis, and treatment due to genetic and sociobehavioral factors. Conducting CaP clinical trials (CTs) in Africa presents multiple opportunities to improve upon collective knowledge of CaP in MAA experiences, expand patient access to CTs, and provide opportunities for African scientists and urologists to contribute to research on the global stage. The International Registry of Men with Advanced Prostate Cancer (IRONMAN) seeks to reduce CaP disparities by sponsoring sites throughout Africa. Four Prostate Cancer Transatlantic Consortium (CaPTC) institutions in Nigeria currently participate in IRONMAN: University of Ilorin Teaching Hospital, Federal Medical Center, University of Maiduguri, and Lagos State University Teaching Hospital. Because CTs of this scale are infrequently conducted in Africa, there are special considerations when conducting CTs in low-middle-income countries (LMICs) like Nigeria. Methods: Hourlong interviews dedicated to site staff were conducted via Zoom in Spring 2023 (four total). Interviews utilized a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis approach. Each interview was recorded, transcribed, and validated by study staff for accuracy. Themes from each were inductively coded and then collated across all four sites. Results: The urologists, oncologists, phlebotomists, pathologists, nurses, research coordinators that make up the study teams identified the holistics of conducting the IRONMAN study at their sites. Strengths included a large patient population to recruit from and appropriate resources to conduct the study (ex., lab space, clinical knowledge, staffing levels). Weaknesses included the social determinants of health that negatively impact patient participation, limited biorepository space to store samples, and the need for patient-physician trust. The greatest opportunity presented was Nigerian institutions joining more CTs in the future, particularly multi-site global trials. Described threats included staff turnover, national stability, and increased economic disparities. Discussion: While increasing the overall number of CTs in Africa is a noble cause, sponsors and institutions should note the unique circumstances in implementing CTs in Africa when designing CTs and recruiting sites. Listening to the experiences of study teams is pivotal in ensuring CTs are Africa-minded - they will be complimentary to established research infrastructure, appropriately funded, and culturally responsive all in the name of equitable research. By doing so, ethical compliance and quality data collection will ensue and reduce disparities at the micro, mezzo, and macro levels.

Abstract Background: Though widely recognized in cancer pathogenesis, inflammatory pathways of allostatic load remain vaguely understood. A partial explanation may be found within the realm of food insecurity and micronutrient inadequacies, defined as nutrient intake less than the estimated average requirement. Many micronutrient deficiencies contribute to pro-inflammatory and immunocompromised milieus. Inadequacies, however, which may present without overt symptoms, are not currently well studied. The purpose of this study was to examine relationships between known inflammation-associated nutritional biomarkers of micronutrients and biomarker variables of allostatic load. Methods: Using NHANES 2017/2018 surveys, adults > 18 years without renal or hepatic disorders, pregnancy, alcohol, or supplement use were included. Plasma levels of vitamins A, B9, C, D, E, calcium (Ca), ferritin (Fe), phosphorus (P), potassium (K) and sodium (Na) were grouped into deficiency, inadequate and adequate groups based on clinically recognized standards. Micronutrient prevalence was assessed and variables of allostatic load [blood pressure, glucose, albumin, creatinine, red cell distribution width (RDW), high density lipoprotein (HDL), low density lipoprotein (LDL), cholesterol and triglycerides] were analyzed for mean differences among micronutrient groups, food security and poverty. Results: From 3,317 unique participants, inadequacy prevalence percentages were quantified as: vitamins A (0.4%), B9 (12.2%), C (58.3%), D (39.6%), E (21.0%), P (11.4%), K (3.4%), Na (24.2%), Ca (59.5%), and Fe (37.4%) [p < 0.001]. Statistically significant differences were identified in age [C, D, E, Ca, Fe, P, Na (p < 0.004)], race/ethnicity [B9, C, D (p < 0.006)], gender [C, E, Ca, Fe, P, K, Na (p < 0.018)], poverty [A, B9, C, D, E, Fe, K (p < 0.025)], and food security [B9, C, D, E, P (p < 0.032)]. Associations to allostatic load were discovered in: albumin [A, C, D, Ca, Fe, P, Na (p < 0.025)], glucose [C, E, Fe, P, Na (p < 0.009)], HDL [C, D, E, Fe, P, K (p<0.045)], LDL [E, Ca, Fe, Na (p<0.028)], creatinine [C, D, Ca, Fe (p<0.001)], triglycerides [B9, D, E, Fe (p<0.033)], cholesterol [C, D, E, Ca, Fe, Na (p<0.006)], B/P [C, E, Fe, P, Na (p < 0.035)], and RDW [C, D, Ca, Fe (p < 0.001)]. Poverty was significantly associated with all variables of allostatic load (F = 2.85, p = 0.002). Food security was significantly correlated with albumin (p < 0.001), glucose (p = 0.005) and HDL (p < 0.001). Conclusion: Allostatic load, poverty, and food security were significantly associated with subclinical micronutrient statuses, which may not present with signs of deficiency and are not currently well assessed. Similarly, poverty was significantly associated with all variables of allostatic load, though food security was only identified to be associated with albumin, glucose, and HDL, suggesting that food security may not be currently adequately defined for surveillance.

Abstract Background: Prostate cancer (PCa) in men is, to date, the number one cause of death from cancer worldwide. PCa has been associated with a large number of lifestyle factors, including unhealthy dietary habits. In particular, diet and nutrition have been shown to play pivotal roles in PCa, and the habitual consumption of certain specific foods like meat cooked at very high temperatures has been implicated. However, this has not been documented among Black men. The aim of this study was to determine the association between dietary patterns and their association with the occurrence of prostate cancer. Method: This is a longitudinal multisite Prostate Cancer Transatlantic Consortium (CaPTC) familial cohort phase 2 study. Participants were Nigerian Black men between 35 and 70 years old who were willing to participate in the study over a 10-year period. For the food variety score, a score of 1 was given for each food item eaten weekly, and the aggregate food variety score was totaled and categorized as ≥54% very good, 45%–53% was good, 36%–44% fair, 18%–35% poor and <18% was very poor. Data were analyzed using descriptive statistics, such as frequency analyses. Chi-square analysis was used to evaluate dichotomous variables to compare groups based on demographic factors and the occurrence of PCa. Multivariate logistic regression was used to determine the specific predictors of the diagnosis of PCa with potential adjustment for the other demographic variables. P-values < 0.05 was set as significant. Results: A total of 780 participants were recruited, with 72.6% reporting no history of cancer. The median age was 47.00 (range: 21-97),16.5% have been diagnosed with Pca, and 1.5% were diagnosed with other Cancers. Age of cancer diagnosis showed that 21% were diagnosed at about 50 years. Participants’ fruit consumption showed that 28.4%, 29%, 39.5%, 23%, 31%, 28.7%, and 39.2, ate apples, mango, citrus, papaya, green banana, tomatoes, and watermelon, weekly, respectively. Fish was the most consumed protein source of animal origin irrespective of the cooking methods categories, such as boiling, frying, grilling, and smoking. The median food variety score was 20 (0-67), with 8.5%, 3.8%,49.3%, and 26.8% classified as good, very good, poor, and very poor, respectively. Multivariate analysis showed that the category of food variety score (P=0.0009), age (P<0.0001), and grilled fish consumption (P=0.0333) were found to be associated with Pca occurrence. Conclusions: The study showed that food variety score, age, and fish consumption were the correlates of prostate cancer occurrence in the population studied. Citation Format: Opeyemi O.

Abstract Background: Equitable representation in research remains a critical issue. Barriers to diversity in research have been identified across personal, provider, and health systems levels. To achieve true health equity, investigators must creatively collaborate with community stakeholders for increased education and partnership. The Mayo Clinic Community Engagement in Research and Clinical Trial (CERCT) curriculum was developed in 2022 to improve the inclusivity and diversity of frontline community-based health workers in research, including community health workers (CHWs), pharmacy technicians, health advocates, and citizen scientists. Aim: The CERCT curriculum was designed to empower and improve the skills necessary for engaging members of the communities about research and clinical trial (CT) participation. Aims for this project include beta pilot training of key community stakeholders in underserved minoritized communities, evaluating the efficacy of CERCT modules through increased recruitment into the Mayo Clinic Florida Community Research Registry; and increased diverse representation in research studies. Methods: This project will train community health advocate cohorts in educating the community on the importance and benefits of participating in research and CT and how to effectively communicate that information within their circles of influence both at work and where they live. Five community health advocate cohorts in Florida counties will be trained through 2-hour online modules, taken at their leisure. Results: Eight online module units will be utilized for beta training of CHWs, pharmacy technicians, health advocates and citizen scientists. Modules include explaining importance of biomedical research and CT; recognizing the different types of research and human participation studies; describing the importance/need of increased representation and inclusion; identifying how the safety, welfare, and well-being of participants are protected at every step in the research process; understanding the role of healthcare providers in research participation; learning communication strategies and tools to raise awareness of CT; examining at an in-depth level the informed consent process and conversation with potential participants; and learning to build trust and address common patient concerns and questions. Efficacy will be assessed via community enrollment in the Mayo Clinic Community Research Registry. Conclusion: Currently, community health workers and pharmacy technicians are an underexplored avenue for disseminating CT education and research inclusivity. The development and beta testing of a curricula specifically created for key community stakeholders who may or may not work in the healthcare or research fields seeks to empower those members with the education to inform their communities and increase representation in science. Designed for increasing education, dispelling common misperceptions, and an easy format, these modules are expected to increase the reach of research into historically underrepresented communities.

Abstract INTRODUCTION In the past decade, Jacksonville, Florida has seen an increase in African immigrants. However, little is known about their health needs and perspectives related to community health and clinical trials. The Mayo Clinic Comprehensive Cancer Center (MCCCC) Community Outreach and Engagement (COE) Office and Programs partnered with multiple community-based organizations as part of the FL Community Engagement Alliance Against COVID-19 to hold a series of focus groups with African immigrants to better understand their perspectives surroudning these determinants. METHODS This was a qualitative study with African immigrants residing in Jacksonville, Florida. Data was collected by community partner, Jocelyn Turner Consulting, who has led multiple community-based studies in Florida. Recruitment was in partnership with African businesses and churches. Using a guide developed by MCCCC COE, three focus groups were held to explore African immigrants’ 1) general experiences, 2) access to social services, 3) perspective of community health and diseases, 4) access and use of healthcare services, 5) knowledge and participation in clinical trials, and 6) appropriate strategies for providing community education and enhancing participation in research studies. RESULTS 24 participants participated in the focus groups. 83% had recently immigrated from Africa (Democratic of the Congo, Benin, Ghana, Sudan, Mali, Nigeria, Ethiopia, and Nigeria). The remaining 17% recently immigrated from Haiti or came to the US as a baby. Participants reported suprise to the proliferation of chronic diseases, such as increased cancer diagnoses of those who immigrated to the United States. Most participants associated this with the Western sedentary lifestyle, dietary habits, and lack of access to fresh food. Participants connected to refugee organizations reported knowledge of the ability to access health education resources and mental/physical care services, but those not connected with similar organizations expressed limited knowledge about access. Similarly, participants with no connection to refugee organizations reported not knowing where to access healthcare services and not seeking services until home remedies had failed. Only 33% of participants reported knowledge of clinical trials and all reported mistrust of research. Many of the participants expressed a need for health-related information upon arrival in the United States. CONCLUSION There is currently little infrastructure in place to support African immigrants in Jacksonville, Florida, which can contribute to cancer health disparities in this population. Strong community engagement is needed to partner with African immigrant communities to address culturally specific needs identified of this underrepresented population. The needs expressed by participants include information on physical activity, nutrition, and healthcare/clinical trials. A strong partnership with African immigrant communities has the potential to address cancer disparities and increase both trust and participation in clinical trials.

Abstract Background: In the United States, many underrepresented minorities experience health disparities in preventative options, access to care, and participation in research. There remains a critical need for robust inclusiveness and diversity to achieve comprehensive participation in research and true health equity. Community health workers (CHWs) and pharmacy technicians may be an overlooked segment in increasing the community reach necessary in alleviating health disparities. Training individuals from and trusted by the community to educate and discuss the importance of research participation may prove an important community engagement method for achieving diversity in clinical trials. Aim: This Community Engagement in Research and Clinical Trial (CERCT) program aims to develop a training curriculum on clinical trials education and inclusivity in research for CHWs and pharmacy technicians. Methods: The CERCT program utilized qualitative methodology in expert in-depth interview sessions with clinical trials and education experts. An appropriate curriculum, content, and mode of training delivery for the program were identified. Interviews also critically reviewed the scientific information most crucial to disseminate to CHWs and Pharmacist technicians, defined the criteria for selecting the most appropriate scientific information for this level of community health partners, and characterized editorial and media management of the training modules. Results: Eleven CERCT modules were developed comprising the importance and benefits of taking part in research and biomedical trials and how to communicate it to others. Modules included 1) history of clinical trials, including past overreach and the need for biomedical research with humans; 2) human participant research studies education, including qualitative and quantitative components; 3) the difference between behavioral, biomedical, and clinical trials; 4) CHW roles in education of research participation, 5) effective communication strategies, 6) research ethics, 7) human subject protection training, 8) the role of the institutional review board, 9) eligibility to consent, 10) vulnerable populations, and 11) Good Clinical Practice training. Conclusion: Community health workers and pharmacy technicians are not a consistent avenue for disseminating clinical trial education and research inclusivity benefits. The development of a curriculum aimed at CHWs and pharmacy technicians seeks to empower more community members with the education to inform their communities and increase representation in science. By creatively engaging and educating active community partners about clinical trials, health disparities in chronic diseases such as cancer, may be alleviated. Citation Format: Jennifer M.

Abstract Background: Access to health care is important for prostate cancer (CaP) screening and control. There is evidence of the racial disparities in health access of black men and Hispanics; however, the comparison between black men's access to health in the United States and those in Africa has not been fully elucidated. Aim: This study aims to evaluate health access and willingness to screen for CaP among black men in Nigeria, Cameroon, and United States. Methods: The Prostate Cancer Transatlantic Consortium (CaPTC) family cohort study phase 1 data of 500 community-dwelling black men in Nigeria, Cameroon, and the United States between 35 and 70 years were used in this study. The association between healthcare access and the willingness to screen for CaP was assessed. The data were described using numbers and percentages; Chi-square was used to test for the association between healthcare access and willingness to screen for CaP. P-values < 0.05 was set as significant. Results: The study showed that 86.1% were from Nigeria, 6.1% from Cameroon, and 7.8% from the United States. Most (75.6%) had never had prostate specific antigen (PSA) screening, and 87.8% had never had digital rectal examination (DRE). Willingness to screen was found in 36.8%, while 11.6% could not decide to screen; 27.4% and 33% were willing to screen for DRE and PSA, respectively. Majority (83.8%) had no access to medical doctors in the last 12 months, and the country of residence was not found to improve access to health (p= 0.378). Healthcare insurance coverage was more available to the US participants with 68.4%, 42.9% in Nigeria, and 16.7% in Cameroon. Overall willingness to screen, willingness for DRE and PSA screening were significantly associated with the country of residence with p-values of 0.02, <0.01, and <0.01, respectively. Having healthcare coverage was also associated with overall willingness to screen (p=0.033). Conclusions: The study showed that country of residence was not associated with health access; however, willingness for CaP screening was significantly associated with the country of residence and healthcare insurance coverage.
