Towards improving stroke services in Africa: Results from the Africa-UK Stroke Partnership [AUKSP] surveys.

BACKGROUND: The African Stroke Organization (ASO) in partnership with the University of Central Lancashire's Stroke Research Team launched the Africa-UK Stroke Partnership (AUKSP). AUKSP undertook two (stroke expert and hospital Stroke Unit (SU)) on-line surveys mapping existing capacity and capability to deliver African stroke care. METHODS: An on-line expert survey tool was sent to 139 stroke experts in 54 African countries October 2021-March 2022 and the hospital SU survey to 120 hospital SUs (identified from the expert survey) June-October 2022. Both survey tools were prepared according to the World Stroke Organisation's Roadmap for Delivering Quality Stroke Care. Completed responses were exported from Qualtrics into Microsoft excel and were analysed descriptively. RESULTS: Forty-five expert responses and 62 hospital SU responses were analysed, representing 54(87%) public hospitals, 7(11%) private and 1(2%) charitable organization. In both surveys, three main priorities for improvement of stroke services were: a rapid and prompt stroke diagnosis; effective primary and secondary stroke prevention, and acute stroke management. Survey findings suggest that there is a low presence of national stroke surveillance systems and registries, and heterogeneity in availability of diagnostic services, SUs, endovascular treatments, and rehabilitation. CONCLUSION: Significant gaps exist in Africa's capacity and capability to deliver essential elements of effective and quality stroke care. Tackling these challenges requires urgent and sustained multi-stakeholder action including: government, administrators, policy makers and other partners. Our survey findings highlight key priority areas for multi-stakeholder engagement and crafting of a pragmatic, prioritized and context-sensitive African Stroke Action Plan.

Telerehabilitation - historical perspectives and conceptual framework in reference to neurological disorders: A narrative review.

BACKGROUND: Telerehabilitation as a new subdiscipline of telehealth is the application of information technology to support and deliver rehabilitation services via two-way or multipoint interactive online telecommunication technology. This enables the therapist to optimize the timing, intensity, and duration of therapy which is often not possible within the constraints of face-to-face treatment protocols in current health systems. OBJECTIVE: To review the historical perspective and conceptual framework of telerehabilitation in neurological disorders. METHODS: A narrative review of the literature was performed for the historical perspective and a systematic review of the conceptual framework was performed using the PRISMA guidelines on chronic neurological disorders; multiple sclerosis, spinal cord injury, stroke, Parkinson's disease, cognitive impairment, and headaches. The search included articles from the past 20 years (2004 to 2024). RESULTS: Telerehabilitation dates back to the 1960s and early 1970s. Documented effective interventions were mostly on therapies for speech disorders. The conceptual framework consisted of three major components of telerehabilitation programmes including development, implementation, and evaluation. The COVID-19 pandemic suddenly made telerehabilitation come to the limelight because physical distancing became necessary. Out of the 110,000 articles downloaded, 43 met the inclusion criteria for review on the conceptual framework of telerehabilitation in relation to neurological disorders. The articles discussed multiple sclerosis (2), spinal cord disorders (1), stroke (17), Parkinson's disease (15), headaches (3), and cognitive disorders (5). All articles reviewed assessed the effectiveness of telemedicine except for the articles on multiple sclerosis and spinal cord disorders which examined the interphase between the technology and the end users. CONCLUSION: The future of telerehabilitation looks promising with the subsequent integration of innovative tools and applications. This will require the adaption of technology, continuous capacity building, education, and training of healthcare professionals to ensure that they are adequately equipped with the necessary skills to provide quality virtual reality rehabilitation care.

National plans and awareness campaigns as priorities for achieving global brain health.

Neurological conditions are the leading cause of death and disability combined. This public health crisis has become a global priority with the introduction of WHO's Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders 2022-2031 (IGAP). 18 months after this plan was adopted, global neurology stakeholders, including representatives of the OneNeurology Partnership (a consortium uniting global neurology organisations), take stock and advocate for urgent acceleration of IGAP implementation. Drawing on lessons from relevant global health contexts, this Health Policy identifies two priority IGAP targets to expedite national delivery of the entire 10-year plan: namely, to update national policies and plans, and to create awareness campaigns and advocacy programmes for neurological conditions and brain health. To ensure rapid attainment of the identified priority targets, six strategic drivers are proposed: universal community awareness, integrated neurology approaches, intersectoral governance, regionally coordinated IGAP domestication, lived experience-informed policy making, and neurological mainstreaming (advocating to embed brain health into broader policy agendas). Contextualised with globally emerging IGAP-directed efforts and key considerations for intersectoral policy design, this novel framework provides actionable recommendations for policy makers and IGAP implementation partners. Timely, synergistic pursuit of the six drivers might aid WHO member states in cultivating public awareness and policy structures required for successful intersectoral roll-out of IGAP by 2031, paving the way towards brain health for all.

Determinants of First-Ever Stroke Severity in West Africans: Evidence From the SIREN Study.

Background Baseline stroke severity is probably partly responsible for poor stroke outcomes in sub-Saharan Africa. However, there is a paucity of information on determinants of stroke severity among indigenous Africans. We sought to identify the factors associated with stroke severity among West Africans in the SIREN (Stroke Investigative Research and Educational Networks) study. Methods and Results Stroke was diagnosed clinically and confirmed with brain neuroimaging. Severe stroke was defined as a Stroke Levity Scale score of ≤5. A multivariate logistic regression model was constructed to identify factors associated with stroke severity at 95% CI and a nominal cutoff of 5% type 1 error. A total of 3660 stroke cases were included. Overall, 50.7%% had severe stroke, including 47.6% of all ischemic strokes and 56.1% of intracerebral hemorrhage. Factors independently associated with severe stroke were meat consumption (adjusted odds ratio [aOR], 1.97 [95% CI, 1.43-2.73]), low vegetable consumption (aOR, 2.45 [95% CI, 1.93-3.12]), and lesion volume, with an aOR of 1.67 (95% CI, 1.03-2.72) for lesion volume of 10 to 30 cm3 and aOR of 3.88 (95% CI, 1.93-7.81) for lesion volume >30 cm3. Severe ischemic stroke was independently associated with total anterior circulation infarction (aOR, 3.1 [95% CI, 1.5-6.9]), posterior circulation infarction (aOR, 2.2 [95% CI, 1.1-4.2]), and partial anterior circulation infarction (aOR, 2.0 [95% CI, 1.2-3.3]) compared with lacunar stroke. Increasing age (aOR, 2.6 [95% CI, 1.3-5.2]) and lesion volume >30 cm3 (aOR, 6.2 [95% CI, 2.0-19.3]) were independently associated with severe intracerebral hemorrhage. Conclusions Severe stroke is common among indigenous West Africans, where modifiable dietary factors are independently associated with it. These factors could be targeted to reduce the burden of severe stroke.

Improving brain and vascular health at the population level: Lessons from the Norwegian success story.

Stroke, dementia and ischemic heart disease are a triple threat which combined are the leading causes of death and disability globally. Fortunately, the three diseases share similar risk factors along the vascular cascade which can be targeted for primordial and primary prevention. In Norway, during 1990-2019, the age-standardised incidence rates decreased significantly for dementia by -5.4%, ischemic heart disease by -30.0%, and stroke by -35.3%. This was possible because Norway ensured equitable income for her citizens, and committed sufficient funds to universal health coverage while implementing a semi-decentralized and responsive health system with robust primary health care. This included monitoring the burden of the triple threat and their cardinal risk factors; ensuring primordial, primary and secondary preventive interventions; implementing acute care for ischemic heart disease and stroke; and ensuring interdisciplinary rehabilitation and chronic care for the triple threat. Overall, all countries will need to develop national strategies for combating the triple threat within the context of sustainable development goals with adequate allocation and utilization of resources.

Effect of an Educational Intervention for Primary Stroke Risk Reduction in Ghana and Nigeria: Pilot Randomized Controlled Trial.

BACKGROUND: Using tailored mobile health interventions to improve global vascular risk awareness and control is yet to be investigated for primary stroke prevention in Africa. METHODS: This 2-arm pilot randomized controlled trial involved 100 stroke-free adults with at least 2 vascular risk factors for stroke. Eligible participants were assigned randomly to a control arm offering 1-time counseling (n=50) or a 2-month educational intervention arm (n=50) comprising a stroke video and riskometer app aimed at improving stroke risk factor awareness and health-seeking behavioral modification to control total vascular risk. Reduction in total stroke risk score was the primary outcome while feasibility and process measures were secondary outcomes. RESULTS: All enrolled participants completed the 2-month follow-up (retention rate=100%). The mean (SD) age of participants was 59.5 (±12.5) years, 38% were males. The mean change in stroke risk score at 2 months was -11.9% (±14.2) in the intervention arm versus -1.2% (±9.1) in the control arm, P=0.0001. Stroke risk awareness improved by 16.1% (±24.7) in the intervention arm versus 8.9% (±24.7) in the control arm, P=0.08. The intervention arm had 11.1 mm Hg reduction in systolic blood pressure compared with 4.8 mm Hg reduction in the control arm. CONCLUSIONS: The intervention demonstrated a positive signal of effect over a 2-month period. A definitive clinical trial with a longer duration of follow-up is warranted on the premise of these promising findings from this pilot randomized clinical trial. REGISTRATION: URL: https://www.

Global synergistic actions to improve brain health for human development.

The global burden of neurological disorders is substantial and increasing, especially in low-resource settings. The current increased global interest in brain health and its impact on population wellbeing and economic growth, highlighted in the World Health Organization's new Intersectoral Global Action Plan on Epilepsy and other Neurological Disorders 2022-2031, presents an opportunity to rethink the delivery of neurological services. In this Perspective, we highlight the global burden of neurological disorders and propose pragmatic solutions to enhance neurological health, with an emphasis on building global synergies and fostering a 'neurological revolution' across four key pillars - surveillance, prevention, acute care and rehabilitation - termed the neurological quadrangle. Innovative strategies for achieving this transformation include the recognition and promotion of holistic, spiritual and planetary health. These strategies can be deployed through co-design and co-implementation to create equitable and inclusive access to services for the promotion, protection and recovery of neurological health in all human populations across the life course.

Capacity-Building for Stroke Genomic Research Data Collection: The African Neurobiobank Ethical, Legal, and Social Implications Project Experience.

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.

Sociodemographic and behavioural risk factors for obesity among community-dwelling older adults in Ghana and Nigeria: A secondary analysis of data from the SIREN study.

OBJECTIVES: To explore the prevalence and risk factors of obesity among older adults from low- and middle-income countries (LMICs). METHODS: This is a secondary analysis of data obtained from the SIREN study through in-person interviews and measurements from healthy stroke-free older adults (≥60 years). Overweight/obesity was defined as body mass index ≥25 kg/m2. Abdominal obesity was defined as waist-to-hip ratio (WHR) of >0.90 for males and >0.85/females or waist circumference (WC) of >102 cm for males/>88 cm for females. Adjusted odds ratio (aORs) with 95% confidence interval (CIs) of the relationship between obesity and sociodemographic factors were assessed at P < 0.05. RESULTS: Overall, 47.5% of participants were overweight/obese, 76.6% had a larger than recommended WHR, and 54.4% had a larger than recommended WC. Abdominal obesity (WC; aOR: 9.43, CI: 6.99-12.50), being a Nigerian (aOR: 0.55; CI: 0.42-0.72), living in an urban setting (aOR: 1.92; CI: 1.49-2.46), earning >$100/month (aOR: 1.53; CI: 1.19-1.96), and having formal education (aOR: 1.42; CI: 1.08-1.87) were associated with overweight/obesity. CONCLUSION: Living in urban settings, earning a higher income, and having a formal education were associated with a higher odds of obesity among older adults from LMICs.

Dietary patterns associated with stroke among West Africans: A case-control study.

BACKGROUND: The relationship of diet with stroke risk among Africans is not well understood. AIM: The aim of this study was to investigate the association between dietary patterns and stroke risk among West Africans. METHODS: In this multi-center case-control study, 3684 stroke patients matched (for age and sex) with 3684 healthy controls were recruited from Nigeria and Ghana. Food consumption was assessed using a food frequency questionnaire, and dietary patterns were summarized using principal component analysis. Stroke was defined using predefined criteria primarily on clinical evaluation following standard guidelines. Conditional logistic regression was applied to compute odds ratio (OR) and 95% confidence interval (CI) for stroke risk by tertiles of dietary patterns adjusting for relevant confounders. RESULTS: Overall, mean age was 59.0 ± 13.9 years, and 3992 (54.2%) were males. Seven dietary patterns were identified. Multivariable-adjusted OR (95% CI) for risk of stroke by second and third tertiles (using the lowest and first tertile as reference) of dietary patterns was 1.65 (1.43, 1.90) and 1.74 (1.51, 2.02), for "poultry product and organ meat"; 1.69 (1.47, 1.96) and 1.51 (1.31, 1.75) for "red meat"; 1.07 (0.92, 1.23) and 1.21 (1.04, 1.40) for "fried foods and sweetened drinks"; 0.69 (0.60, 0.80) and 0.45 (0.39, 0.53) for "vegetables"; 0.84 (0.72, 0.97) and 0.81 (0.70, 0.93) for "whole-grain and fruit drinks"; and 0.97 (0.84, 1.12) and 0.85 (0.73, 0.98) for "fruits" respectively (p < 0.05). CONCLUSION: These data suggest that plant-based diets are associated with a lower risk of stroke and might be a beneficial dietary recommendation for the primary prevention of stroke among Africans.

Day and night blood pressure variability among older persons in South-Western Nigeria.

Background: Hypertension is the largest contributor to the global burden of disease. Emerging risk factors for cardiovascular disease include blood pressure variability (BPV), but evidence on BPV is lacking among older Nigerians. We reported BPV in a cohort of older persons at the University College Hospital (UCH), Ibadan. Methods: We conducted a retrospective cohort study of respondents aged >50 years within the Ibadan Ambulatory Blood Pressure Registry at the UCH, Ibadan, Nigeria. Socio-demographic characteristics, lifestyle habits and anthropometric measurements were obtained. Results: Among 639 respondents, 332 (52.0%) were female. The blood pressure (BP) variables were strongly associated with age. Compared with younger age groups, mean diastolic BP (DBP) was less at an older age, whereas mean pulse pressure was greater. During the wake-up and sleep periods, mean DBP and mean arterial BP were less with each increasing age category, whereas mean pulse pressure was larger with each increasing age category. BP dipping, systolic, diastolic and mean arterial BP decreased with age. Overall, timed BPV increased significantly with increasing age. The prevalence of white-coat hypertension was greater among older participants than younger participants. Most respondents in the 50-59 years' age group were non-dippers (55.8%), whereas 33.7% of older respondents were reverse-dippers. Conclusion: Older persons experienced a greater abnormal circadian blood variation and greater BPV than younger people. In Nigeria, follow-up data are needed to determine the prognostic significance of these data in this population.
