Factors associated with balance impairments amongst stroke survivors in northern Benin: A cross-sectional study

BACKGROUND: Balance impairment is the predominant risk factor for falls in stroke survivors. A fear of falling after stroke can contribute to sedentary lifestyles, increased disability and risk of recurrence, leading to poor quality of life. OBJECTIVE: To determine the frequency and factors associated with balance impairments amongst stroke survivors at the University Hospital of Parakou. METHOD: This cross-sectional study included adult stroke survivors. Stroke survivors after discharge were enrolled at the University Hospital of Parakou between 01 January 2020 and 30 September 2020. Balance impairments were measured by using the Berg Balance Scale (BBS), the Timed Up and Go (TUG) and the Get Up and Go (GUG) tests. RESULTS: A total of 54 stroke survivors were included, with a mean age of 58.37 ± 12.42 years and a male predominance of 68.52%. The mean BBS score was 36.87 ± 14.34 with a minimum and a maximum of 10 and 56, respectively. Thirteen (24.07%) had balance impairments (BBS score ≤ 20), 34 (62.96%) had a TUG score ≥ 14 s (abnormal), 9 (16.67%) presented a moderate risk of falling and 6 (11.11%) presented high risk of fall with the GUG test. Post-stroke duration (odds ratio [OR] = 0.04; 95% CI: 0.04-0.30; p < 0.01), severity of disability (OR = 8.33; 95% CI: 1.03-67.14; p = 0.03) and the number of physiotherapy sessions (OR = 0.18; 95% CI: 0.03-0.93; p = 0.02) were significantly associated with balance impairments. CONCLUSION: Our results showed that almost one quarter of stroke survivors after discharge at the University Hospital of Parakou had balance impairments. Post-stroke duration, severity of disability and the number of physiotherapy sessions were significantly associated with balance impairments. CLINICAL IMPLICATIONS: [AQ1] Balance should be regularly assessed in people post-stroke. Further studies should document the content of rehabilitation and any rehabilitative efforts to improve balance in people post-stroke in Benin

More than 4,000 case–control pairs have already been recruited to the study and several publications on stroke phenom-ics and preliminary candidate gene analyses have been generated. The SIREN study has also undertaken the first-ever GWAS to unravel the genetic architecture of stroke in Indigenous Africans and the results are eagerly awaited. Stroke neurobanking resources consisting of blood fractions, extracted DNA, neuroimages and databases of clinical information are also being built in Africa and could facilitate data science-driven trans-omics research (including epigenomics, tran-scriptomics, proteomics and metabolomics) as well as the development of precision medicine products such as Afrocentric risk calculators, polygenic risk scores, biomarkers and drug targets23–25,227,307,308. The SIREN neurobiobank comprises a group of constantly monitored ultra-low-temperature (–86 °C) freezers located in Ibadan, Nigeria, constantly powered –20 °C chest freezers located in Ibadan and other recruitment sites, barcode scanners and printers, a laboratory information management system, a secure multi-terabyte server,Stroke is a leading cause of disability, dementia, and death worldwide. Approximately 70% of deaths from stroke and 87% of stroke-related disabilities occur in low-income and middle-income countries. At the turn of the century, the most common diseases in Africa were communicable diseases, whereas non-communicable diseases, including stroke, were considered rare, particularly in sub-Saharan Africa. However, evidence indicates that today, Africa could have up to 2–3-fold greater rates of stroke incidence and higher stroke prevalence than western Europe and the USA. In Africa, data published within the past decade show that stroke has an annual incidence rate of up to 316 per 100,000, a prevalence of up to 1,460 per 100,000, and a 3-year fatality rate greater than 80%. Moreover, many Africans have a stroke within the fourth to sixth decades of life, with serious implications for the individual, their family, and society. This age profile is particularly important as strokes in younger people tend to result in a greater loss of self-worth and socioeconomic productivity than in older individuals. Emerging insights from research into stroke epidemiology, genetics, prevention, care, and outcomes offer great prospects for tackling the growing burden of stroke on the continent. In this article, we review the unique profile of stroke in Africa and summarize current knowledge on stroke epidemiology, genetics, prevention, acute care, rehabilitation, outcomes, cost of care, and awareness. We also discuss knowledge gaps, emerging priorities, and future directions of stroke medicine for the more than 1 billion people who live in Africa. © 2021, Springer Nature Limited.Newcastle National Institute for Health Research Biomedical Research Centre in Ageing and Age-Related Diseases Newcastle upon Tyne Hospitals National Health Service Foundation Trust RCUK Newcastle Centre for Brain Ageing and Vitality Royal Society/African Academy of Sciences: FCG/R1/ 201034,FLR/R1/191813 National Institutes of Health (NIH): R01NS107900 Wellcome Trust (WT) Medical Research Council (MRC): G0500247 Dunhill Medical Trust (DMT) Academy of Medical Sciences: U01HG010273,U54HG007479 Alzheimer’s Research UK (ARUK

Risk of emergency hospital admission in children associated with mental disorders and alcohol misuse in the household: an electronic birth cohort study

Background: Mental disorders and alcohol misuse are common in families but their effects on the physical health of children are not known. We investigated the risk of emergency hospital admissions during childhood associated with living with an adult who has a mental health disorder, or who had an alcohol-related hospital admission. Methods: We did this cohort study in a total population electronic child cohort in Wales, UK, which includes all children who live in Wales or with a mother who is resident in Wales. We used Cox regression to model time to first emergency hospital admission during the first 14 years of life associated with living with an adult who has a mental health disorder, or who had an alcohol-related hospital admission. We adjusted our results for social deprivation and perinatal risk factors.Findings: We included data for 253 717 children with 1 015 614 child-years of follow-up. Living with an adult with a mental disorder was associated with an increased risk of emergency admission for all causes (adjusted hazard ratio [aHR] 1·17, 95% CI 1·16–1·19), for injuries and external causes (1·14, 1·11–1·18), and childhood victimisation (1·55, 1·44–1·67). Children living with a household member who had an alcohol-related hospital admission had a significantly higher risk of emergency admissions for injuries and external causes (aHR 1·13, 95% CI 1·01–1 ·26) and victimisation (1·39, 1·00–1·94), but not for all-cause emergency admissions (1·01, 0·93–1·09).Interpretation: The increased risk of emergency admissions in children associated with mental disorders and alcohol misuse in the household supports the need for policy measures to provide support to families that are affected.Funding: Economic and Social Research Council, Medical Research Council, Alcohol Research UK, Public Health Wales

An Estimate of the Incidence and Prevalence of Stroke in Africa:A Systematic Review and Meta-Analysis

Background: Stroke is increasingly becoming a challenging public health issue in Africa, and the non-availability of data has limited research output and consequently the response to this burden. This study aimed to estimate the incidence and prevalence of stroke in Africa in 2009 towards improved policy response and management of the disease in the region. Methods: A systematic search of Medline, EMBASE and Global Health for original population-based or hospital-based studies on stroke was conducted. A random effect meta-analysis was conducted on crude stroke incidence and prevalence rates, and a meta-regression-like epidemiological model was applied on all data points. The fitted curve generated from the model was used to estimate incident cases of stroke and number of stroke survivors in Africa at midpoints of the United Nation population 5-year age groups for the year 2009. Results: The literature search yielded a total of 1227 studies. 19 studies from 10 African countries were selected. 483 thousand new stroke cases among people aged 15 years or more were estimated in Africa in 2009, equivalent to 81.2 (13.2– 94.9)/100,000 person years. A total of 1.89 million stroke survivors among people aged 15 years or more were estimated in Africa in 2009, with a prevalence of 317.3 (314.0–748.2)/100000 population. Comparable figures for the year 2013 based on the same rates would amount to 535 thousand (87.0–625.3) new stroke cases and 2.09 million (2.06–4.93) stroke survivors, suggesting an increase of 10.8% and 9.6% of incident stroke cases and stroke survivors respectively, attributable to population growth and ageing between 2009 and 2013. Conclusion: The findings of this review suggest the burden of stroke in Africa is high and still increasing. There is need for more research on stroke and other vascular risk factors towards instituting appropriate policy, and effective preventive and management measures

The role of community advisory boards in enhancing recruitment and retention in Alzheimer\u27s disease and related dementia research in Africa: Experience from the READD-ADSP study

\ua9 2025 The Author(s). Alzheimer\u27s &amp; Dementia published by Wiley Periodicals LLC on behalf of Alzheimer\u27s Association.INTRODUCTION: The Recruitment and Retention of Alzheimer\u27s Disease Diversity Genetic Cohorts in the Alzheimer\u27s Disease Sequencing Project (READD–ADSP) was established to bridge the gap in Alzheimer\u27s disease and related dementias (ADRD) research in Africa. We examined the role of Community Advisory Boards (CABs) in improving participant recruitment and retention in ADRD research in Africa, by exploring how culturally sensitive engagement, community trust-building, and stakeholder involvement influence research participation. METHODS: A multi-site, multi-phased qualitative study approach that involved establishment of CABs, initial planning meetings and community engagement cum recruitment activities. RESULTS: Twenty-one CABs (141 members) were established across 14 study sites in 9 African Dementia Consortium (AfDC) member countries. Co-creation planning meetings, culturally sensitive outreaches for brain health, dementia awareness creation, and recruitment were held. DISCUSSION: Establishing CABs within the READD–ADSP project has proven instrumental in co-creating culturally appropriate and community-centered strategies for recruitment and retention in ADRD research in Africa. Highlights: The Recruitment and Retention of Alzheimer\u27s Disease Diversity Genetic Cohorts in the Alzheimer\u27s Disease Sequencing Project (READD-ADSP) project utilizes a community-engaged research (CER) framework to develop a community engagement program and establish Community Advisory Boards (CABs) to enhance participant recruitment and retention. There is a need to standardize CER practices and promote context-sensitive and culturally appropriate CE activities across African Dementia Consortium (AfDC) sites to ensure cultural sensitivity and enhance recruitment and retention. The project seeks to empower CABs to promote national dementia policies by collaborating with policy-makers and advancing equitable dementia scienced and care in Africa

Developing biobanking processes for Alzheimer\u27s disease and related dementia research in Africa: Experience from the Recruitment and Retention for Alzheimer\u27s Disease Diversity in the Alzheimer\u27s Disease Sequencing Project (READD-ADSP)

\ua9 2025 The Author(s). Alzheimer\u27s &amp; Dementia published by Wiley Periodicals LLC on behalf of Alzheimer\u27s Association.The Recruitment and Retention for Alzheimer\u27s Disease Diversity in the Alzheimer\u27s Disease Sequencing Project (READD-ADSP) aims to recruit 5000 African participants (Alzheimer\u27s disease [AD] and cognitively unimpaired controls) to generate genomic and biomarker data to better characterize AD neurobiology in Africa from countries that constitute the African Dementia Consortium (AfDC). Blood samples from study participants are separated into fractions and transported to the African Coordinating Centre (ACC: Ibadan, Nigeria), where DNA extraction and long-term biospecimen storage are carried out. Plasma and DNA aliquots are shipped to the John P. Hussman Institute for Human Genomics, University of Miami (HIHG-UM, Miami, USA) for genotyping, whole genome sequencing, and biomarker analysis. Innovative solutions were devised to mitigate challenges encountered so far. Our biobanking experience in a low-resource setting demonstrates the feasibility of establishing a successful African biobanking network, as an important infrastructure to support Alzheimer\u27s disease and related dementias research in Africa. Highlights: Biobanking is gaining grounds in Africa in studies related to neurological disorders. The Recruitment and Retention for Alzheimer\u27s Disease Diversity in the Alzheimer\u27s Disease Sequencing Project (READD-ADSP) biobanking network is a new initiative to enhance infrastructure for Alzheimer\u27s disease and related dementias (ADRD) research in Africa through the African Dementia Consortium. The processes of the stepwise creation and development of the READD-ADSP biobanking network have been guided by global best practices and regulatory standards. Challenges were encountered in the process of establishing the READD-ADSP biobank, and home-grown solutions were developed to mitigate the challenges. The READD-ADSP biobanking experience offers lessons to researchers in low-resource settings on how collaborative efforts between the global north and global south enhance cutting-edge team science to tackle ageing-associated brain disorders in low- and middle-income countries
