ABSTRACT
Background: There is a growing interest in stroke genomics and neurobiobanking research in Africa. These raise several ethical issues, such as consent, re-use, data sharing, storage, and incidental result of biological samples. Despite the availability of ethical guidelines developed for research in Africa, there is paucity of information on how the research participants' perspectives could guide the research community on ethical issues in stroke genomics and neurobiobanking research. To explore African research participants' perspectives on these issues, a study was conducted at existing Stroke Investigation Research and Education Network (SIREN) sites in Nigeria and Ghana. Method: Using an exploratory design, twenty-eight Focus Group Discussions (FGDs) sessions were conducted with stroke survivors (n=7), caregivers(n=7), stroke - free controls(n=7), and Community Advisory Board members(n=7). Data were collected using an interview guide. Interviews were conducted in English and indigenous languages of the community, audio recorded, and transcribed verbatim. Data were analyzed using NVivo (March, 2020) Software. Result: Results revealed that stroke genomics and neurobiobanking research in Africa require researchers' direct attention to ethical issues. Concerns were raised about understanding, disclosure and absence of coercion as components of true autonomous decision making in research participation. Participants argued that the risk and benefits attached to participation should be disclosed at the time of recruitment. Fears around data sharing were voiced as adherence to the principle of privacy and confidentiality were of paramount importance to participants. The preference was to receive the results of incidental findings with no stigma attached from society. Conclusion: Research participants' perspectives are a vital aspect of community engagement in stroke genomics and neurobiobanking research. Findings from this study suggest that research participants are interested in these fields of research in Africa if their concerns about ethical issues are appropriately addressed within the research framework.
ABSTRACT
Background: The fields of stroke genomics, biobanking, and precision medicine are rapidly expanding in sub-Saharan Africa. However, the ethical, legal, and social implications (ELSI) of emerging neurobiobanking and genomic data resources are unclear in an emerging African scientific landscape with unique cultural, linguistic, and belief systems. Objective: This article documents capacity-building experiences of researchers during the development, pretesting, and validation of data collection instruments of the African Neurobiobank for Precision Stroke Medicine-(ELSI) Project. Methods: The African Neurobiobank for Precision Stroke Medicine-ELSI project is a transnational, multicenter project implemented across seven sites in Ghana and Nigeria. Guided by the Community-Based Participatory Research framework, we conducted three workshops with key stakeholders to review the study protocol, ensure uniformity in implementation; pretest, harmonize, and integrate context-specific feedback to ensure validity and adaptability of data collection instruments. Workshop impact was assessed using an open-ended questionnaire, which included questions on experience with participation in any of the workshops, building capacity in Genetic and Genomic Research (GGR), level of preparedness toward GGR, the genomic mini-dictionary developed by the team, and its impact in enhancing understanding in GGR. Data were analyzed qualitatively using a thematic framework approach. Results: Findings revealed the usefulness of the workshop in improving participants' knowledge and capacity toward GGR implementation. It further identified local, context-specific concerns regarding quality data collection, the need to develop culturally acceptable, genomic/biobanking data collection tools, and a mini-dictionary. Participants-reported perceptions were that the mini-dictionary enhanced understanding, participation, and data collection in GGR. Overall, participants reported increased preparedness and interest in participating in GGR. Conclusion: Capacity-building is a necessary step toward ELSI-related genomic research implementation in African countries where scholarship of ELSI of genomics research is emerging. Our findings may be useful to the design and implementation of ELSI-GGR projects in other African countries.

INTRODUCTION: Genomic research and neurobiobanking are expanding globally. Empirical evidence on the level of awareness and willingness to donate/share biological samples towards the expansion of neurobiobanking in sub-Saharan Africa is lacking. AIMS: To ascertain the awareness, perspectives and predictors regarding biological sample donation, sharing and informed consent preferences among community members in Ghana and Nigeria. METHODS: A questionnaire cross-sectional survey was conducted among randomly selected community members from seven communities in Ghana and Nigeria. RESULTS: Of the 1015 respondents with mean age 39.3 years (SD 19.5), about a third had heard of blood donation (37.2%, M: 42.4%, F: 32.0%, p = 0.001) and a quarter were aware of blood sample storage for research (24.5%; M: 29.7%, F: 19.4%, p = 0.151). Two out of ten were willing to donate brain after death (18.8%, M: 22.6%, F: 15.0%, p<0.001). Main reasons for unwillingness to donate brain were; to go back to God complete (46.6%) and lack of knowledge related to brain donation (32.7%). Only a third of the participants were aware of informed consent (31.7%; M: 35.9%, F: 27.5%, p<0.001). Predictors of positive attitude towards biobanking and informed consent were being married, tertiary level education, student status, and belonging to select ethnic groups. CONCLUSION: There is a greater need for research attention in the area of brain banking and informed consent. Improved context-sensitive public education on neurobiobanking and informed consent, in line with the sociocultural diversities, is recommended within the African sub region.
