Conducting Precision Medicine Research with African Americans

Unveiling Racial Disparities in Localized Prostate Cancer: A Systems-Level Exploration of the lncRNA Landscape

BACKGROUND/OBJECTIVES

Prostate cancer (PC) is the most common non-cutaneous cancer in men globally, and one which displays significant racial disparities. Men of African descent (AF) are more likely to develop PC and face higher mortality compared to men of European descent (EU). The biological mechanisms underlying these differences remain unclear. Long non-coding RNAs (lncRNAs), recognized as key regulators of gene expression and immune processes, have emerged as potential contributors to these disparities. This study aimed to investigate the regulatory role of lncRNAs in localized PC in AF men relative to those of EU and assess their involvement in immune response and inflammation.

METHODS

A systems biology approach was employed to analyze differentially expressed (DE) lncRNAs and their roles in prostate cancer (PC). Immune-related pathways were investigated through over-representation analysis of lncRNA-mRNA networks. The study also examined the effects of vitamin D supplementation on lncRNA expression in African descent (AF) PC patients, highlighting their potential regulatory roles in immune response and inflammation.

RESULTS

Key lncRNAs specific to AF men were identified, with several being implicated for immune response and inflammatory processes. Notably, 10 out of the top 11 ranked lncRNAs demonstrated strong interactions with immune-related genes. Pathway analysis revealed their regulatory influence on antigen processing and presentation, chemokine signaling, and ribosome pathways, suggesting their critical roles in immune regulation.

CONCLUSIONS

These findings highlight the pivotal role of lncRNAs in PC racial disparities, particularly through immune modulation. The identified lncRNAs may serve as potential biomarkers or therapeutic targets to address racial disparities in PC outcomes.

Key contextual factors involved with participation in medical and genomic screening and research for African American and White Americans: a qualitative inquiry

Tremendous progress has been made promoting diversity in recruitment for genomic research, yet challenges remain for several racial demographics. Research has cited intertwined fears of racial discrimination and medical mistrust as contributing factors. This study aimed to identify key factors to establishing trust in medical and genomic screening and research among African Americans and White Americans. Participants completed online focus groups and resulting transcripts were analyzed using a qualitative descriptive approach, with content analysis methods based on recommendations by Schreier. Fifteen African Americans and twenty-three White Americans participated in the study, 63% of which were female. The mean age of participants was 38.5 (SD = 16.6). The Overarching Theme of Trust is Context Dependent was identified, along with the following five themes describing elements influencing trustworthiness for our participants: (1) Professional Experience, Education, and Training Bolster Trust; (2) Trust Depends on Relationships; (3) Cross-checking Provided Information is Influential in Establishing Trust; (4) Trust is Undermined by Lack of Objectivity and Bias; and (5) Racism is an Embedded Concern and a Medical Trust Limiting Component for African Americans. To effectively address mistrust and promote recruitment of diverse participants, genomic research initiatives must be communicated in a manner that resonates with the specific diverse communities targeted. Our results suggest key factors influencing trust that should be attended to if we are to promote equity appropriately and respectfully by engaging diverse populations in genomic research.

Development of a Hereditary Breast and Ovarian Cancer and Genetics Curriculum for Community Health Workers: KEEP IT (Keeping Each other Engaged Program via IT) Community Health Worker Training

We developed a curriculum for community health workers (CHWs) using an innovative, community-engaged focus group and Delphi process approach. Equipping CHWs with knowledge of hereditary breast and ovarian cancer syndrome (HBOC) and genetics could help enhance identification of women at risk for HBOC, referral, and navigation through genetic services. We conducted focus groups with five CHWs and a three-round Delphi process with eight experts. In the first round of the Delphi process, participants rated and commented on draft curriculum modules. The second round involved live video discussion to highlight points of confusion and concern in the modules. The curriculum was revised and refined based on quantitative and qualitative data and reassessed by the experts in Round 3. Ultimately, agreement was achieved on eight of 10 modules when assessing for clarity of learning objectives, seven out of 10 when assessing for adult learning theory, and nine out of 10 when assessing for participants' ability to learn desired knowledge. We plan to virtually deliver this curriculum to CHWs to enhance their HBOC and genomic competencies. By equipping CHWs to understand and participate in genomics education, we can enable more equitable participation in genomics-informed clinical care and research. Beyond this curriculum, the Delphi methodology can further be used to design content for new CHW curriculums.

Understanding men's beliefs and concerns about linking health data in the context of precision medicine

Background/Objective

Linking data is a critical feature of precision medicine initiatives that involves integrating information from multiple sources to improve researchers' and clinicians' ability to deliver care. We have limited understanding of how individuals perceive linking data as it relates to precision medicine. The aim of this study was to identify how sociodemographics, comorbidities, and beliefs about precision medicine influence two outcomes related to linking data: beliefs about linking data and concerns about linking data among men.

Methods

We recruited 124 adult men from primary care practices at a large clinical research university to complete a cross-sectional survey that included questions about sociodemographic characteristics, comorbidities, beliefs, benefits, and limitations of precision medicine, and two outcomes of interest: beliefs about the value of linking data and concerns about linking data. Descriptive statistics, bivariate associations, and multivariable regression were conducted.

Results

Participants had positive beliefs about linking data for precision medicine (M = 4.05/5) and average concern about linking data (M = 2.1/5). Final multivariable models revealed that higher levels of loneliness are associated with more positive beliefs about linking data (β = 0.41, p = 0.027). Races other than African American (β = -0.64, p = 0.009) and those with lower perceived limitations of precision medicine were less likely to be concerned about linking data (β = -0.75, p = 0.0006).

Conclusion

Our results advance the literature about perceptions of linking data for use in clinical and research studies among men. Better understanding of factors associated with more positive perceptions of data linkages could help improve how researchers recruit and engage participants.

Assessing the role of interactivity: An evaluation of information aids to support the enrollment of precision medicine research programs

OBJECTIVE

Recruiting diverse participants for precision medicine (PM) research programs should overcome low literacy and varied expectations. Information aids (IA) can address these barriers through patient-centered education. The purpose of this study was to evaluate the effectiveness of three information aids (IA) on participating in PM.

METHODS

An experiment with 290 U.S. participants recruited from Mturk was conducted to compare the effects of three IAs on the outcomes related to participation. Three conditions included an interactive IA (i.e., providing PM-related information responding to each participant's questions), a static IA (i.e., providing uniform PM-related information), and a control condition (i.e., providing non-interactive information irrelevant to PM).

RESULTS

Both interactive and non-interactive IAs increased attitudes and information-seeking intentions, but not knowledge or participation intention. Perceived control and responsiveness mediated the effects of interactive IA.

CONCLUSION

Both interactive and static IAs supported enrollment efforts for PM through fostering attitudes and follow-up information-seeking. Increased perceived control and responsiveness are key to the effects of interactive IA.

PRACTICE IMPLICATIONS

IAs provide effective education and enrollment support for PM. Interactive IA can respond to individuals' inquiries and control the learning process.

Review of genetic and pharmacogenetic differences in cytotoxic and targeted therapies for pancreatic cancer in African Americans

Pancreatic ductal adenocarcinoma (PDAC) is currently the third leading cause of cancer mortality and the incidence is projected to increase by 2030. Despite recent advances in its treatment, African Americans have a 50-60% higher incidence and 30% higher mortality rate when compared to European Americans possibly resulting from differences in socioeconomic status, access to healthcare, and genetics. Genetics plays a role in cancer predisposition, response to cancer therapeutics (pharmacogenetics), and in tumor behavior, making some genes targets for oncologic therapeutics. We hypothesize that the germline genetic differences in predisposition, drug response, and targeted therapies also impact PDAC disparities. To demonstrate the impact of genetics and pharmacogenetics on PDAC disparities, a review of the literature was performed using PubMed with variations of the following keywords: pharmacogenetics, pancreatic cancer, race, ethnicity, African, Black, toxicity, and the FDA-approved drug names: Fluoropyrimidines, Topoisomerase inhibitors, Gemcitabine, Nab-Paclitaxel, Platinum agents, Pembrolizumab, PARP-inhibitors, and NTRK fusion inhibitors. Our findings suggest that the genetic profiles of African Americans may contribute to disparities related to FDA approved chemotherapeutic response for patients with PDAC. We recommend a strong focus on improving genetic testing and participation in biobank sample donations for African Americans. In this way, we can improve our current understanding of genes that influence drug response for patients with PDAC.

Testing a deliberative democracy method with citizens of African ancestry to weigh pros and cons of targeted screening for hereditary breast and ovarian cancer risk

Background

Democratic deliberation (DD), a strategy to foster co-learning among researchers and communities, could be applied to gain informed public input on health policies relating to genomic translation.

Purpose

We evaluated the quality of DD for gaining informed community perspectives regarding targeting communities of African Ancestry (AAn) for Hereditary Breast and Ovarian Cancer (HBOC) screening in Georgia.

Methods

We audiotaped a 2.5 day conference conducted via zoom in March 2021 to examine indicators of deliberation quality based on three principles: (1) inclusivity (diverse viewpoints based on participants' demographics, cancer history, and civic engagement), (2) consideration of factual information (balanced and unbiased expert testimonies, participant perceived helpfulness), and (3) deliberation (speaking opportunities, adoption of a societal perspective on the issue, reasoned justification of ideas, and participant satisfaction).

Results

We recruited 24 participants who reflected the diversity of views and life experiences of citizens of AAn living in Georgia. The expert testimony development process we undertook for creating balanced factual information was endorsed by experts' feedback. Deliberation process evaluation showed that while participation varied (average number of statements = 24, range: 3-62), all participants contributed. Participants were able to apply expert information and take a societal perspective to deliberate on the pros and cons of targeting individuals of AAn for HBOC screening in Georgia.

Conclusions

The rigorous process of public engagement using deliberative democracy approach can successfully engage a citizenry with diverse and well-informed views, do so in a relatively short time frame and yield perspectives based on high quality discussion.

Ethical considerations for precision psychiatry: A roadmap for research and clinical practice

Precision psychiatry is an emerging field with transformative opportunities for mental health. However, the use of clinical prediction models carries unprecedented ethical challenges, which must be addressed before accessing the potential benefits of precision psychiatry. This critical review covers multidisciplinary areas, including psychiatry, ethics, statistics and machine-learning, healthcare and academia, as well as input from people with lived experience of mental disorders, their family, and carers. We aimed to identify core ethical considerations for precision psychiatry and mitigate concerns by designing a roadmap for research and clinical practice. We identified priorities: learning from somatic medicine; identifying precision psychiatry use cases; enhancing transparency and generalizability; fostering implementation; promoting mental health literacy; communicating risk estimates; data protection and privacy; and fostering the equitable distribution of mental health care. We hope this blueprint will advance research and practice and enable people with mental health problems to benefit from precision psychiatry.

Equity in Genomic Medicine

Since the completion of the Human Genome Project, considerable progress has been made in translating knowledge about the genetic basis of disease risk and treatment response into clinical services and public health interventions that have greater precision. It is anticipated that more precision approaches to early detection, prevention, and treatment will be developed and will enhance equity in healthcare and outcomes among disparity populations. Reduced access to genomic medicine research, clinical services, and public health interventions has the potential to exacerbate disparities in genomic medicine. The purpose of this article is to describe these challenges to equity in genomic medicine and identify opportunities and future directions for addressing these issues. Efforts are needed to enhance access to genomic medicine research, clinical services, and public health interventions, and additional research that examines the clinical utility of precision medicine among disparity populations should be prioritized to ensure equity in genomic medicine. Expected final online publication date for the Annual Review of Genomics and Human Genetics, Volume 23 is October 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Examining access to care in clinical genomic research and medicine: Experiences from the CSER Consortium

INTRODUCTION

Ensuring equitable access to health care is a widely agreed-upon goal in medicine, yet access to care is a multidimensional concept that is difficult to measure. Although frameworks exist to evaluate access to care generally, the concept of "access to genomic medicine" is largely unexplored and a clear framework for studying and addressing major dimensions is lacking.

METHODS

Comprised of seven clinical genomic research projects, the Clinical Sequencing Evidence-Generating Research consortium (CSER) presented opportunities to examine access to genomic medicine across diverse contexts. CSER emphasized engaging historically underrepresented and/or underserved populations. We used descriptive analysis of CSER participant survey data and qualitative case studies to explore anticipated and encountered access barriers and interventions to address them.

RESULTS

CSER's enrolled population was largely lower income and racially and ethnically diverse, with many Spanish-preferring individuals. In surveys, less than a fifth (18.7%) of participants reported experiencing barriers to care. However, CSER project case studies revealed a more nuanced picture that highlighted the blurred boundary between access to genomic research and clinical care. Drawing on insights from CSER, we build on an existing framework to characterize the concept and dimensions of access to genomic medicine along with associated measures and improvement strategies.

CONCLUSIONS

Our findings support adopting a broad conceptualization of access to care encompassing multiple dimensions, using mixed methods to study access issues, and investing in innovative improvement strategies. This conceptualization may inform clinical translation of other cutting-edge technologies and contribute to the promotion of equitable, effective, and efficient access to genomic medicine.

Opportunities to Improve Women's Health: Engaging Racial/Ethnic Diverse Women to Provide Biospecimens for Research

Objective: Inclusion of women in biomedical cancer research have the potential to close gaps in cancer health disparities and improve adjuvant therapies for women; yet samples needed to advance this area of science are lacking. We developed low-cost educational recruitment strategies to increase our collection of biospecimens from women. Materials and Methods: Women diagnosed with hormone receptor positive (HR+) breast cancer that initiated hormonal therapy were recruited from three integrated health systems. The analytical sample (n = 144) consisted of women who consented but did not return a saliva sample within 1 year of the initial assessment (baseline). Brief informational recruitment materials were developed via published literature and preliminary data. Women received recruitment materials, which included a personalized information letter, a colorful low-literacy instruction sheet, a postage-paid envelope, and collection kits. We evaluated intervention materials and performed descriptive and bivariate statistics to describe factors associated with biospecimen donation. Results: Of the total sample, 61% were white and 34% were black. Overall, 29 surveys (20%) and 25 (17%) saliva kits were returned. Women found the materials helpful and easy to read and understand. Women with higher levels of functional well-being and lower ratings of religiosity were more likely to return biospecimens (p < 0.005) after receiving enhanced materials. Conclusion: This article provides recruitment strategies to enhance biospecimen samples among women. Receipt of brief informational print materials inclusive of personalized messages enhanced our outreach strategies and increased our overall biospecimen provision rate by 17%. The inclusion of messages with a focus on spirituality and other cultural messages may further increase biospecimen provision in racial/ethnic diverse groups of women; however, further study is needed to support this claim. Clinical Trail Registration Number: NCT02992730.

Engagement and return of results preferences among a primarily African American genomic sequencing research cohort

Genomics researchers are increasingly interested in what constitutes effective engagement of individuals from underrepresented groups. This is critical for longitudinal projects needed to inform the implementation of precision medicine. Return of results is one opportunity for engagement. The aims of this study were to determine participant perspectives on optimal engagement strategies and priorities for return of results and the extent to which focus groups were an effective modality for gathering input on these topics. We conducted six professionally moderated focus groups with 49 participants in a genomics research study. Transcripts from audio-recorded sessions were coded by two researchers and themes were discussed with the wider research team. All groups raised the issue of mistrust. Individuals participated nonetheless to contribute their perspectives and benefit their community. Many group members preferred engagement modalities that are offered to all participants and allow them to share the nuances of their perspectives over the use of participant representatives and surveys. All groups created a consensus ranking for result return priorities. Results for life-threatening conditions were the highest priority to return, followed by those related to treatable conditions that affect physical or mental health. We advocate for engagement strategies that reach as many participants as possible and allow them to share their perspectives in detail. Such strategies are valued by participants, can be effective for developing return of results policies, and may help institutions become more trustworthy.

Structural Racism in the COVID-19 Pandemic: Moving Forward

The COVID-19 pandemic has taken a substantial human, social and economic toll globally, but its impact on Black/African Americans, Latinx, and American Indian/Alaska Native communities in the U.S. is unconscionable. As the U.S. continues to combat the current COVID-19 cycle and prepares for future pandemics, it will be critical to learn from and rectify past and contemporary wrongs. Drawing on experiences in genomic research and intersecting areas in medical ethics, health disparities, and human rights, this article considers three key COVID-19-related issues: research to identify remedies; testing, contact tracing and surveillance; and lingering health needs and disability. It provides a pathway for the future: community engagement to develop culturally-sensitive responses to the myriad genomic/bioethical dilemmas that arise, and the establishment of a Truth and Reconciliation Commission to transition the country from its contemporary state of segregation in healthcare and health outcomes into an equitable and prosperous society for all.

The Florida Pancreas Collaborative Next-Generation Biobank: Infrastructure to Reduce Disparities and Improve Survival for a Diverse Cohort of Patients with Pancreatic Cancer

Background: Well-annotated, high-quality biorepositories provide a valuable platform to support translational research. However, most biorepositories have poor representation of minority groups, limiting the ability to address health disparities. Methods: We describe the establishment of the Florida Pancreas Collaborative (FPC), the first state-wide prospective cohort study and biorepository designed to address the higher burden of pancreatic cancer (PaCa) in African Americans (AA) compared to Non-Hispanic Whites (NHW) and Hispanic/Latinx (H/L). We provide an overview of stakeholders; study eligibility and design; recruitment strategies; standard operating procedures to collect, process, store, and transfer biospecimens, medical images, and data; our cloud-based data management platform; and progress regarding recruitment and biobanking. Results: The FPC consists of multidisciplinary teams from fifteen Florida medical institutions. From March 2019 through August 2020, 350 patients were assessed for eligibility, 323 met inclusion/exclusion criteria, and 305 (94%) enrolled, including 228 NHW, 30 AA, and 47 H/L, with 94%, 100%, and 94% participation rates, respectively. A high percentage of participants have donated blood (87%), pancreatic tumor tissue (41%), computed tomography scans (76%), and questionnaires (62%). Conclusions: This biorepository addresses a critical gap in PaCa research and has potential to advance translational studies intended to minimize disparities and reduce PaCa-related morbidity and mortality.

ChicagO Multiethnic Prevention and Surveillance Study (COMPASS): Increased Response Rates Among African American Residents in Low Socioeconomic Status Neighborhoods

African American (AA) populations experience persistent health disparities in the USA. Low representation in bio-specimen research precludes stratified analyses and creates challenges in studying health outcomes among AA populations. Previous studies examining determinants of bio-specimen research participation among minority participants have focused on individual-level barriers and facilitators. Neighborhood-level contextual factors may also inform bio-specimen research participation, possibly through social norms and the influence of social views and behaviors on neighbor's perspectives. We conducted an epidemiological study of residents in 5108 Chicago addresses to examine determinants of bio-specimen research participation among predominantly AA participants solicited for participation in the first 6 years of ChicagO Multiethnic Prevention and Surveillance Study (COMPASS). We used a door-to-door recruitment strategy by interviewers of predominantly minority race and ethnicity. Participants were compensated with a $50 gift card. We achieved response rates of 30.4% for non-AA addresses and 58.0% for AA addresses, with as high as 80.3% response among AA addresses in low socioeconomic status (SES) neighborhoods. After multivariable adjustment, we found approximately 3 times the odds of study participation among predominantly AA addresses in low vs. average SES neighborhoods (odds ratio (OR) = 3.06; 95% confidence interval (CI) = 2.20-4.24). Conversely, for non-AA addresses, we observed no difference in the odds of study participation in low vs. average SES neighborhoods (OR = 0.89; 95% CI = 0.69-1.14) after multivariable adjustment. Our findings suggest that AA participants in low SES neighborhoods may be recruited for bio-specimen research through door-to-door approaches with compensation. Future studies may elucidate best practices to improve bio-specimen research participation among minority populations.

In Different Voices: The Views of People with Disabilities about Return of Results from Precision Medicine Research

PURPOSE

Returning genetic results to research participants is gaining momentum in the USA. It is believed to be an important step in exploring the impact of efforts to translate findings from research to bedside and public health benefits. Some also hope that this practice will incentivize research participation, especially among people from historically marginalized communities who are commonly underrepresented in research. However, research participants' interest in receiving nongenomic medical and nonmedical results that may emerge from precision medicine research (PMR) is understudied and no study to date has explored the views of people with disabilities about return of genomic and nongenomic results from PMR.

METHODS

In a national online survey of people with disabilities, participants were queried about their interest in receiving biological, environmental, and lifestyle results from PMR (n = 1,294). Analyses describe findings for all of the participants and comparisons for key demographic characteristics and disability subgroups.

RESULTS

The participants expressed high interest in biological and health-related results and less interest in other findings. However, the interest among the study participants was lower than that found in comparable studies of the general population. Moreover, this interest varied significantly across gender, race/ethnicity, and disability subgroups. Possible reasons for these differences are discussed.

CONCLUSION

Insofar as return of results from PMR may impact translational efforts, it is important to better understand the role of sociomedical marginalization in decisions about return of results from PMR and to develop strategies to address existing barriers.

Understanding Participation in Genetic Research Among Patients With Multiple Sclerosis: The Influences of Ethnicity, Gender, Education, and Age

This study examined reasons for participation in a genetic study of risk for multiple sclerosis (MS). Our sample consisted of 101 patients diagnosed with MS who were approached about enrolling in the Multiple Sclerosis Genetic Susceptibility Study. Participants were predominantly Hispanic (80%), female (80%), and well educated (71%), having at least some level of college education. Of these 101 individuals who were approached, 95 agreed to participate and are the focus of this report. Among enrollees, the most frequently cited reasons for participation were to find a cure for MS (56%), having MS (46%), and helping future generations (37%). Regression models comparing ethnic groups, Hispanics endorsed having MS as a reason to participate significantly more frequently than non-Hispanics (HI 52%, non-HI 19%, p = 0.015) while non-Hispanics endorsed finding new and better treatments significantly more frequently than Hispanics (Hispanic 17%, non-Hispanic 50%, p = 0.003). Among our three age groups, younger individuals endorsed finding a cure for MS significantly more frequently (74% of 18-35-year olds vs. 56% of 36-55 year olds vs. 39% of >55 year olds). Our results suggest that motivations for participation in genetic research vary by ethnicity, and that these influences need to be considered in developing more inclusive programs of disease-related genetic research. Future efforts should focus on development of standard methods for understanding participation in genetic and genomic research, especially among underrepresented groups as a catalyst for engaging all populations.

"I'm a Little More Trusting": Components of Trustworthiness in the Decision to Participate in Genomics Research for African Americans

AIMS

This study sought to explore the decision to participate in genomics research for African American individuals. Our overall goal was to explore (1) the attributes that significantly contribute to willingness to participate in genomics research; (2) how these attributes are interpreted (what is their meaning?); (3) how trustworthiness is estimated in the decision to participate in research (i.e., what are the symbolic representations or heuristics of trustworthiness in decision-making?); and (4) how participants see factors to counterweigh each other.

METHODS

We sought a methodology that would afford exploration of the compensatory nature of decision-making where some choice attributes may be weighed differently than others as well as the use of heuristics (shortcuts to estimate key concepts in the mentally taxing task of decision-making) for concepts such as trustworthiness. We used a qualitative story deck to create hypothetical research scenarios with variable attributes (i.e., researcher race/ethnicity; institutional affiliation; research goal; and biospecimen requested) to determine how individuals find and interpret information to make decisions about research participation. These semi-structured interviews (n = 82) were conducted in African American barbershops in Baltimore City and Prince George's County, Maryland.

RESULTS

Quantitative and qualitative analysis was completed. Findings include that, even in the absence of interpersonal connection, trustworthiness can be communicated through multiple factors, such as (1) shared values with researchers and (2) familiarity. Conversely, (1) ambiguity, especially regarding the use of biospecimens, (2) negative reputations, and (3) perceptions of "hidden agendas" were associated with a lower willingness to participate. However, the alignment of participant and research goals was weighed more heavily in decisions than other factors.

CONCLUSION

This study finds that negatively assessed characteristics in research design do not result in automatic rejections of participation. Negative assessments can be mitigated by emphasizing the multiple factors that communicate trustworthiness in the consent process, which may improve rates of research participation.

The role of race and ethnicity in views toward and participation in genetic studies and precision medicine research in the United States: A systematic review of qualitative and quantitative studies

BACKGROUND

Racial/ethnic minority populations in the United States are consistently underrepresented in genetic research. Large-scale public participation is required to ensure discoveries from precision medicine research are applicable to everyone. To evaluate views toward and facilitators of participation among minority populations in the United States, we conducted a systematic review of literature.

METHODS

Six databases were searched for articles published from 2005 to 2018 assessing minority populations' views and/or willingness to participate in genetic research. A thematic framework was applied to extracted data to synthesize findings, and the Socio-Ecological Model was used to evaluate papers.

RESULTS

Review of 2,229 titles and abstracts identified 27 papers (n = 8 qualitative, n = 19 quantitative). Themes included knowledge of genetics, engagement in research, facilitators and barriers to participation, and cultural considerations. Understanding of genetics was low, yet the majority of participants were willing to participate in genetic research among all populations included in the literature (range: 57%-97%). Recommendations for research included utilizing community-based participatory approaches, evaluating participants' informational needs, incentivizing participation, and providing direct benefits (e.g., genetic test results).

CONCLUSION

Results could influence future study designs that incorporate all levels of the Socio-Ecological Model and better meet the needs of underrepresented groups, thereby ensuring precision medicine research findings are applicable to all.

Best Practices for Obtaining Genomic Consent in Pediatric Traumatic Brain Injury Research

BACKGROUND

Precision health relies on large sample sizes to ensure adequate power, generalizability, and replicability; however, a critical first step to any study is the successful recruitment of participants.

OBJECTIVES

This study seeks to explore how the enrollment strategies used in a parent study contributed to the high consent rates, establish current best practices that can be used in future studies, and identify additional factors that contribute to consent into pediatric traumatic brain injury biobanks.

METHODS

Retrospective secondary analysis of data from a parent study with high consent rates was examined to explore factors affecting consent into biobanking studies.

RESULTS

Of the 76 subjects who were approached, met the eligibility criteria, and reviewed the consent form, only 16 (21.1%) declined to participate. The consented group (n = 60) represents 64.5% of those who met the eligibility criteria upon initial screening (n = 93) and 78.9% of those with confirmed eligibility (n = 76). Analysis of screening data suggested there were no major barriers to consenting individuals into this pediatric traumatic brain injury biobank.

DISCUSSION

There were no demographic or research-related characteristics that significantly explained enrollment. Ethically, to obtain true informed consent, parents need to understand only their child's diagnosis, prognosis, and medical care, as well as the purpose of the proposed research and its risks and benefits. Researchers need to implement best practices, including a comprehensive review of census data to identify eligible participants to approach, a prescreening protocol, and effective consenting process to obtain informed consent so that precision care initiatives can be pursued.

A Review of African Americans' Beliefs and Attitudes About Genomic Studies: Opportunities for Message Design

Precision Medicine, the practice of targeting prevention and therapies according to an individual’s lifestyle, environment or genetics, holds promise to improve population health outcomes. Within precision medicine, pharmacogenomics (PGX) uses an individual’s genome to determine drug response and dosing to tailor therapy. Most PGX studies have been conducted in European populations, but African Americans have greater genetic variation when compared with most populations. Failure to include African Americans in PGX studies may lead to increased health disparities. PGX studies focused on patients of African American descent are needed to identify relevant population specific genetic predictors of drug responses. Recruitment is one barrier to African American participation in PGX. Addressing recruitment challenges is a significant, yet potentially low-cost solution to improve patient accrual and retention. Limited literature exists about African American participation in PGX research, but studies have explored barriers and facilitators among African American participation in genomic studies more broadly. This paper synthesizes the existing literature and extrapolates these findings to PGX studies, with a particular focus on opportunities for message design. Findings from this review can provide guidance for future PGX study recruitment.

Precision health research and implementation reviewed through the conNECT framework

BACKGROUND

Precision health is a population-based approach that incorporates big-data strategies to understand the complex interactions between biological, environmental, lifestyle, and psychosocial factors that influence health.

PURPOSE

A promising tool to facilitate precision health research and its dissemination is the ConNECT Framework.

METHODS

Here, we discuss the relationship of the five broad and synergistic principles within the ConNECT Framework as they may apply to nursing science research: (1) Integrating Context, (2) Fostering a Norm of Inclusion, (3) Ensuring Equitable Diffusion of Innovations, (4) Harnessing Communication Technology, and (5) Prioritizing Specialized Training.

DISCUSSION/CONCLUSION

The principles within this framework can be used by nurse scientists and educators to guide and disseminate precision health research.

Attitudes and experiences regarding genetic research among persons of African descent

Minorities are underrepresented in genetic research. This study examined the attitudes, experiences, and willingness of persons of African descent related to participation in genetic research. A total of 272 persons of African descent completed a questionnaire about attitudes and experiences associated with genetic research. Descriptive, Chi-square, and logistic regression were used to examine the impact of attitudes and experiences in predicting the odds of willingness to participate in genetic research. A majority of participants (97%) indicated that they have never participated in genetic research; however, a majority also reported that they would be willing to participate in a genetic study specifically for the detection of risk factors for cancer (87%), diabetes (89%), alcohol use disorder (73%), and Alzheimer's disease (88%). Participants who disagreed that "results from genetic research can explain why some diseases are found more often in some ethnic groups than others" were less likely to be willing to participate in studies related to cancer (OR = 0.16), diabetes (OR = .16), alcohol use disorder (OR = 0.27), and Alzheimer's disease (OR = 0.27). Participants reported limited experiences engaging in genetic research; yet, they overwhelmingly acknowledged the importance of genetic research and expressed willingness to participate in multifactorial genetic studies despite concerns about genetic discrimination, stigma, and/or a potentially poor prognosis. Further research on the underlying reasons why persons of African descent choose to participate in genetic research should be explored and addressed to make research more inclusive and ethically sound.

Disability inclusion in precision medicine research: a first national survey

PURPOSE

Including people with disabilities in precision medicine research (PMR) is key for increasing cohorts' diversity, improving understanding of population health, and attaining social justice for the United States' largest health disparities group. We conducted a national survey to explore the views of people with disabilities about PMR.

METHODS

An online survey was developed in disability-accessible formats. Key questions included views on PMR, willingness to participate and to provide data, perceived barriers to participation and potential remedies, and interest in engagement in the study. Analyses described results for all participants and compared results for key demographic characteristics.

RESULTS

In total, 1294 participants completed the survey. Participants expressed strong support for PMR, and willingness to participate in PMR; to provide lifestyle, biological, and medical information; and to engage with the study. However, 76% identified a total of 3 to 8 barriers to participation, and most would not provide environmental samples or information from their social media account(s) and activity trackers. Differences were observed across racial, ethnic, and gender groups and are discussed.

CONCLUSIONS

Barriers to disability inclusion need to be removed, and further research conducted to better understand concerns about PMR and to develop studies that resonate with the interests and needs of this population.

IGNITE network: Response of patients to genomic medicine interventions

BACKGROUND

The IGNITE network funds six genomic medicine projects. Though interventions varied, we hypothesized that synergies across projects could be leveraged to better understand the participant experiences with genomic medicine interventions. Therefore, we performed cross-network analyses to identify associations between participant demographics and attitudes toward the intervention (attitude), plan to share results (share), and quality of life (QOL).

METHODS

Data collection for demographics, attitude, share, and QOL surveys were standardized across projects. Recruitment and survey administration varied by each project's protocol.

RESULTS

Participants (N = 6,817) were 67.2% (N = 4,584) female, and 37.4% (N = 3,544) were minority. Mean age = 54.0 (sd 14.a). Younger participants were as follows: (1) more positive in attitude pre-intervention (1.15-fold decrease/10-year age increase (OR)) and more negative after (1.14-fold increase OR); (2) higher in QOL pre-intervention (1.07-fold increase OR) and postintervention; (3) more likely to share results (1.12-fold increase OR). Race was significant when sharing results (white participants increased OR = 1.88), but not for change in QOL pre-postintervention or attitude.

CONCLUSION

Our findings demonstrate the feasibility of this approach and identified a few key themes which are as follows: age was consistently significant across the three outcomes, whereas race had less of an impact than expected. However, these are only associations and thus warrant further study.

Racial and ethnic differences in knowledge and attitudes about genetic testing in the US: Systematic review

Precision medicine has grown over the past 20 years with the availability of genetic tests and has changed the one-size-fits-all paradigm in medicine. Precision medicine innovations, such as newly available genetic tests, could potentially widen racial and ethnic disparities if access to them is unequal and if interest to use them differs across groups. The objective of this systematic review was to synthesize existing evidence on racial and ethnic differences in knowledge of and attitudes toward genetic testing among adult patients and the general public in the US, focusing on research about the use of genetic testing in general, not disease-specific tests. Twelve articles published in 1997-2017 met inclusion and exclusion criteria, with 10 including knowledge variables and seven including attitude variables. Studies found consistent patterns of lower awareness of genetic testing in general among non-Whites compared to Whites, lower factual knowledge scores among Blacks and Hispanics/Latinos, and mixed findings of differences in awareness of direct-to-consumer (DTC) genetic testing or the term precision medicine. Blacks, Hispanics/Latinos, and non-Whites generally had more concerns about genetic testing than Whites. The findings suggest that patients and the general public need access to culturally appropriate educational material about the use of genetic testing in precision medicine.

Improving Community Advisory Board Engagement in Precision Medicine Research to Reduce Health Disparities

Community Advisory Boards (CABs) are used in efforts to reduce health disparities; however, there is little documentation in the literature regarding their use in precision medicine research. In this case study, an academic-CAB partnership developed a questionnaire and patient educational materials for two precision smoking cessation interventions that involved use of genetic or genetically-informed information. The community-engaged research (CEnR) literature provided a framework for enhancing benefits to CAB members involved in developing research documents for use with a low-income, ethnically diverse population of smokers.The academic partners integrated three CEnR strategies: 1) in-meeting statements acknowledging their desire to learn from community partners, 2) in-meeting written feedback to and from community partners, and 3) a survey to obtain CAB member feedback post-meetings. Strategies 1 and 2 yielded modifications to pertinent study materials, as well as suggestions for improving meeting operations that were then adopted, as appropriate, by the academic partners. The survey indicated that CAB members valued the meeting procedure changes which appeared to have contributed to improvements in attendance and satisfaction with the meetings. Further operationalization of relevant partnership constructs and development of tools for measuring these aspects of community-academic partnerships is warranted to support community engagement in precision medicine research studies.

Knowledge, motivations, expectations, and traits of an African, African-American, and Afro-Caribbean sequencing cohort and comparisons to the original ClinSeq® cohort

PURPOSE

Racial minority populations are underrepresented in genomics research. This study enrolled African-descended individuals in a sequencing study and reported their characteristics.

METHODS

We purposively recruited 467 individuals self-identified as African, African American, or Afro-Caribbean to the ClinSeq^® study and surveyed them about knowledge, motivations, expectations, and traits. Summary statistics were calculated and compared with data from the study's original cohort, which was primarily White and self-referred.

RESULTS

Recruitment took five years and 83% of enrollees completed the survey. Participants had modest knowledge about benefits and limitations of sequencing (x̅s = 5.1, ranges: 0-10), and less than the original cohort (x̅ = 7.5 and 7.7, respectively). Common motivations to enroll were learning information relevant to personal health (49%) or family members' health (33%), and most had realistic expectations of sequencing. Like the original cohort, they had high levels of optimism, openness, and resilience.

CONCLUSION

Early adopters may have relatively consistent personality traits irrespective of majority/minority status and recruitment methods, but high levels of genomics knowledge are not universal. Research should determine whether recruitment and consent procedures provide adequate education to promote informed choices and realistic expectations, which are vital to ethical research and increasing genomics research participation in underrepresented communities.

Precision Medicine: Familiarity, Perceived Health Drivers, and Genetic Testing Considerations Across Health Literacy Levels in a Diverse Sample

A clear awareness of a patient's knowledge, values, and perspectives is an important component of effective genetic counseling. Advances in precision medicine, however, have outpaced our understanding of patient perceptions of this new approach. Patient views may differ across the three domains of precision medicine (genetics, behavioral, and environmental determinants of health), ethnic/racial groups, and health literacy levels. This study describes and compares group differences in familiarity, perceptions, and preferences for precision medicine in a diverse sample. Between 2016 and 2017, 252 participants completed a 10-15-min survey in three primary care clinics in Florida and Tennessee. The final sample was 42.5% African American/Black, 25.8% Hispanic/Latino, 25.0% White, and 6.7% other ethnicity/race. Less than a quarter of participants reported being familiar with the term "precision medicine," but were more familiar with basic genetic terms. Participants with higher health literacy reported greater familiarity with terms (p ≤ .003). African Americans/Black participants were more likely to identify ethnicity/race and discrimination as influencing their health (p ≤ .004). When deciding to get a genetic test, individuals across ethnic/racial groups shared similar considerations. Those with higher health literacy, however, gave significantly greater importance to provider trust (p ≤ .008). Given the recent emergence of precision medicine, at present there may be limited differences in patient perceptions across ethnic/racial groups. Culturally sensitive efforts, tailored to health literacy level, may aid equitable precision medicine uptake.

Linking Education to Action: A Program to Increase Research Participation Among African American Women

BACKGROUND

Underrepresentation of African American women as research participants contributes to health disparities. Contemporary studies have focused on clinical trial (CT) participation; epidemiologic and genetic studies utilizing medical records and/or biological samples have received less attention. In partnership with The Links, Incorporated (The Links), a national service organization of professional African American women, this study sought to examine attitudes regarding chart review (CR) studies, genetic studies/biobanking (GEN), and CTs; develop; and evaluate an online education-to-action program.

METHODS

In phase 1, focus groups were convened with members of The Links to inform the content and format of the program. Phases 2 and 3 involved designing and evaluating the program, respectively.

RESULTS

Thirty-four women across three focus groups shared attitudes and perceptions regarding research and provided guidance for program development. Subsequently, 244 women completed the program (77% response rate), including pre- and post-assessments. Participants indicating that they "definitely" or "probably" (responses combined) intend to participate in research increased from 36.5% to 69.3% (pre/post-program). Agreement with the statement "research in the U.S. is ethical" increased (52.9% to 74.4%) as did factual knowledge regarding each of the study types. There was a decrease in reporting "little or no understanding" of study types (Pre/Post: GEN: 66%/24.9%, CR: 62.9%/18.4%, CTs: 40.7%/15.5%). Pre-program, few were "very positive" about the study types (14.3% GEN, 15.0% CR, 28.6% CTs); post-program ratings increased and equalized (42.8% GEN, 43.0% CR, 42.5% CTs).

CONCLUSIONS

An online education-to-action program targeting professional African American women improved knowledge, perceptions of ethics, and intent to participate in biomedical research.

Challenges in recruiting African-American women for a breast cancer genetics study

Background

African-American women, especially in the southern United States, are underrepresented in cancer genetics research. A study was designed to address this issue by investigating the germline mutation rate in African-American women in Arkansas with a personal and/or family history of breast cancer. Women were tested for these mutations using a large panel of breast cancer susceptibility genes. In this analysis, we discuss the challenges encountered in recruiting African-American women from an existing biorepository to participate in this study.

Methods

We attempted to contact 965 African-American women with a personal and/or family history of breast cancer who participated in Spit for the Cure (SFTC) between 2007 and 2013 and provided consent to be recontacted. The SFTC participants were invited by telephone and email to participate in the genetic study. Enrollment required completion of a phone interview to obtain a family and medical history and return of a signed consent form.

Results

Among eligible SFTC participants, 39.6% (382/965) were able to be contacted with the phone numbers and email addresses they provided. Of these, 174 (45.5%) completed a phone interview and returned a signed consent form. Others were not able to be contacted (n = 583), declined to participate (n = 57), did not keep phone interview appointments (n = 82), completed the phone interview but never returned a signed consent (n = 54), were deceased (n = 13), or were too confused to consent to participate (n = 2).

Conclusions

Recruiting African-American women into our breast cancer genetics study proved challenging primarily due to difficulty establishing contact with potential participants. Given their prior participation in breast cancer research, we anticipated that this would be a highly motivated population. Indeed, when we were able to contact SFTC participants, only 14.9% declined to participate in our study. Innovative communication, retention, and recruitment strategies are needed in future studies to address the recruitment challenges we faced.

Beyond Consent: Building Trusting Relationships With Diverse Populations in Precision Medicine Research

With the growth of precision medicine research on health data and biospecimens, research institutions will need to build and maintain long-term, trusting relationships with patient-participants. While trust is important for all research relationships, the longitudinal nature of precision medicine research raises particular challenges for facilitating trust when the specifics of future studies are unknown. Based on focus groups with racially and ethnically diverse patients, we describe several factors that influence patient trust and potential institutional approaches to building trustworthiness. Drawing on these findings, we suggest several considerations for research institutions seeking to cultivate long-term, trusting relationships with patients: (1) Address the role of history and experience on trust, (2) engage concerns about potential group harm, (3) address cultural values and communication barriers, and (4) integrate patient values and expectations into oversight and governance structures.
