    Knowledge, attitudes and practices of West Africans on genetic studies of stroke: Evidence from the SIREN Study

    Background: It is crucial to assess genomic literacy related to stroke among Africans in preparation for the ethical, legal and societal implications of the genetic revolution which has begun in Africa. Objective: To assess the knowledge, attitudes and practices (KAP) of West Africans about stroke genetic studies. Methods: A comparative cross-sectional study was conducted among stroke patients and stroke-free controls recruited across 15 sites in Ghana and Nigeria. Participants’ knowledge of heritability of stroke, willingness to undergo genetic testing and perception of the potential benefits of stroke genetic research were assessed using interviewer-administered questionnaire. Descriptive, frequency distribution and multiple regression analyses were performed. Results: Only 49% of 2029 stroke patients and 57% of 2603 stroke-free individuals knew that stroke was a heritable disorder. Among those who knew, 90% were willing to undergo genetic testing. Knowledge of stroke heritability was associated with having at least post-secondary education (OR 1.51, 1.25–1.81) and a family history of stroke (OR 1.20, 1.03–1.39) while Islamic religion (OR¼0.82, CI: 0.72–0.94), being currently unmarried (OR ¼ 0.81, CI: 0.70–0.92), and alcohol use (OR ¼ 0.78, CI: 0.67–0.91) were associated with lower odds of awareness of stroke as a heritable disorder. Willingness to undergo genetic testing for stroke was associated with having a family history of stroke (OR 1.34, 1.03– 1.74) but inversely associated with a medical history of high blood pressure (OR ¼ 0.79, 0.65–0.96). Conclusion: To further improve knowledge of stroke heritability and willingness to embrace genetic testing for stroke, individuals with less formal education, history of high blood pressure and no family history of stroke require targeted interventions

    Short-term pilot feasibility study of a nurse-led intervention to improve blood pressure control after stroke in Nigeria
    (Elsevier B.V, 2017) Wahab K. W.; Owolabi M.; Akinyemi R.; Jenkins C.; Arulogun O.; Akpa O.; Gebregziabher M.; Uvere E.; Saulson R.; Ovbiagele B.
    Background: Given the paucity of neurologists in Sub-Saharan Africa (SSA), task-shifting post-stroke care to nurses could be a viable avenue for enhancing post-stroke outcomes. This pilot study assessed the feasibility and short-term impact of a nurse-led intervention to manage blood pressure (BP) control in recent stroke survivors in Nigeria. Methods: A randomized pilot trial allocated patients within one month of an index stroke from two participating hospitals in Nigeria to either nurse-led group clinic or standard care for 14 days. Key study endpoints were successful execution of the protocol, subject retention, and short-term BP effects. Results: There were no significant differences between the intervention (n = 17) and control (n = 18) groups at baseline. At the post-intervention clinic, patient retention rate was 100%. In the intervention group, both the systolic and diastolic BPs measured at home were lower than the clinic BPs post-interven tion (127 ± 12.88/78.13 ± 19.26 mmHg versus 137.50 ± 23.05/84.06 ± 9.67 mmHg; p = 0.05). However, there was no significant change in clinic blood pressure (BP) recordings in both the intervention and control groups. Conclusion: It is possible to initiate a nurse-led group clinic intervention to address BP management among stroke survivors in SSA with good early retention of participants. A larger and longer-term trial is being planned.
