Abstract
Background Stroke is a common neurological disorder with a huge global burden in terms of mortality and morbidity. Epidemiological evidence has shown that modifiable risk factors are responsible for more than 90% of all strokes. Stroke outcome in hospitalized patients is influenced by several variables, such as socio-demographic factors, stroke subtype, and admission severity. The interaction between stroke outcomes and these parameters is often complex. The study is aimed to profile hospitalized stroke patients and determine outcome predictors. Methodology A descriptive retrospective study of 100 patients hospitalized for acute stroke. Their medical records were reviewed for demographic and clinical variables and relevant data were retrieved and analysed using appropriate statistical methods. Results Of the 100 acute stroke patients studied, 36% were men and 64% were women. The mean age was 65.16±15.72. About 78%had ischemic stroke while 21% had haemorrhagic strokes. The commonest risk factor was hypertension (71.2%). On multivariate analysis, stroke subtype and admission duration were significantly linked to stroke outcome. Conclusion Ischemic stroke comprises more than two-thirds of stroke admissions, with hypertension being the most common risk factor and stroke case fatality of 23%. Stroke subtype and admission duration significantly predicted stroke outcomes. The need to step up measures aimed at improving acute stroke care in hospitalized patients is imperative as this will hopefully improve overall outcomes in resource constraint settings such as Nigeria.

Abstract
Objectives To determine the stroke risk profile of dwellers of Nnewi community in Nigeria. Methods This was a cross-sectional survey involving consecutively recruited community-dwelling adults without a previous history of stroke. The Modified Framingham Stroke Risk Score (MFSRS) was used to evaluate the stroke risk profile of the participants. Data was analysed using descriptive and inferential statistics at an alpha level of 0.05. Result 310 individuals (mean age = 37.21 ± 15.84 years; 68.7% females) participated in this study. The mean MFSRS (6.79 ± 5.21) of the participants was minimal with 16% having a moderate-to-high risk. Dyslipidaemia (100.0%), meat (88.1%) and sugar (70.6%) consumption, hypertension (37.7%), physical inactivity (43.2%), and psychological stress (41.3%) were the most prevalent risk factors in the population. Participants' MFSRS significantly and positively correlated with their body mass index (BMI), waist circumference (WC), and waist-hip ratio (WHR) and significantly differed across their gender, educational, and occupational categories (p < 0.05). Conclusion According to MFSRS, the risk of stroke among the sampled community was minimal and was significantly influenced by their BMI, WC, WHR, gender, education, and occupation. However, results revealed that stroke risk might be higher in the population than was depicted by the MFSRS. Enlightenment on the risk of stroke is needed in the community.

Abstract
OBJECTIVES To assess the knowledge of community dwelling adults on stroke risk and their willingness to use mobile health (mHealth) technology in assessing their stroke risk. MATERIALS AND METHODS A cross-sectional study was conducted among adults (≥18 years old) using survey questionnaires designed by neurologists and health promotion experts and administered by trained study staff. Logistic regression models were used to assess factors associated with receptivity toward knowing individual stroke risk score and willingness to use a mobile application (App) to assess stroke risk. RESULTS The survey was administered to 486 participants in Nigeria, with a mean age of 47.4 ± 15.5 years, comprising 53.5% females. Up to 84% of participants wanted to know their risk for developing stroke but only 29.6% of respondents had ever previously had their stroke risk assessed. Factors associated with willingness to know stroke risk were age [aOR (95% CI): 0.97 (0.95 - 0.99)], and Hausa tribe [16.68 (2.16 - 128.92)]. Up to 66% of participants wanted to know their immediate risk of stroke, compared with 6.6% and 2.1% who wanted to know their 5-year or 10-year future stroke risks respectively. Regarding locations, participants preferred stroke risk assessment to be performed at a health facility, at home by health professional, on their own using mHealth (stroke risk calculator application), or at communal gatherings (decreasing order). About 70% specifically wished to learn about their stroke risk via an mHealth application. CONCLUSIONS Community dwelling Nigerians wanted to know their immediate risk of stroke using digital platforms, such as a mobile phone stroke risk calculator application. Clinical trials are needed to assess the effectiveness of such a strategy for primary prevention of stroke in sub-Saharan African communities.

Keino BC, Carrel M. Spatial and temporal trends of overweight/obesity and tobacco use in East Africa: subnational insights into cardiovascular disease risk factors. Int J Health Geogr 2023; 22:20. [PMID: 37620831 PMCID: PMC10463724 DOI: 10.1186/s12942-023-00342-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 08/02/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is increasing in Sub-Saharan Africa (SSA). Overweight/obesity and tobacco use are modifiable CVD risk factors, however literature about the spatiotemporal dynamics of these risk factors in the region at subnational or local scales is lacking. We describe the spatiotemporal trends of overweight/obesity and tobacco use at subnational levels over a 13-year period (2003 to 2016) in five East African nations. METHODS Cross-sectional, nationally representative Demographic and Health Surveys (DHS) were used to explore the subnational spatiotemporal patterns of overweight/obesity and tobacco use in Burundi, Kenya, Rwanda, Tanzania, and Uganda, five East African Community (EAC) nations with unique cultural landscapes influencing CVD risk factors. Adaptive kernel density estimation and logistic regression were used to determine the spatial distribution and change over time of CVD risk factors on a subnational and subpopulation (rural/urban) scale. RESULTS Subnational analysis shows that regional and national level analysis masks important trends in CVD risk factor prevalence. Overweight/obesity and tobacco use trends were not similar: overweight/obesity prevalence increased across most nations included in the study and the inverse was true for tobacco use prevalence. Urban populations in each nation were more likely to be overweight/obese than rural populations, but the magnitude of difference varied widely between nations. Spatial analysis revealed that although the prevalence of overweight/obesity increased over time in both urban and rural populations, the rate of change differed between urban and rural areas. Rural populations were more likely to use tobacco than urban populations, though the likelihood of use varied substantially between nations. Additionally, spatial analysis showed that tobacco use was not evenly distributed across the landscape: tobacco use increased in and around major cities and urban centers but declined in rural areas. CONCLUSIONS We highlight the importance of de-homogenizing CVD risk factor research in SSA. Studies of national or regional prevalence trends mask important information about subpopulation and place-specific behavior and drivers of risk factor prevalence. Spatially explicit studies should be considered as a vital tool to understand local drivers of health, disease, and associated risk factor trends, especially in highly diverse yet low-resourced, marginalized, and often homogenized regions.

Abstract
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.

Abstract
IMPORTANCE Psychosocial stress is considered a modifiable risk factor for stroke. Given the prevalence of chronic and acute exposure to stress, it represents a potentially attractive target for population-health interventions. OBJECTIVES To determine the association of psychosocial stress with the risk of acute stroke and explore factors that might modify the association of stress with risk of acute stroke in a large international population. DESIGN, SETTING, AND PARTICIPANTS INTERSTROKE is an international retrospective case-control study of risk factors for first acute stroke in 32 countries in Asia, North and South America, Europe, Australia, the Middle East, and Africa. A total of 13 462 patients with stroke and 13 488 matched controls were recruited between January 11, 2007, and August 8, 2015. The present analyses were performed from June 1 to 30, 2021, and included 13 350 cases and 13 462 controls with available data on psychosocial stress. EXPOSURES Psychosocial stress and occurrence of stressful life events within the preceding year were measured using a standardized questionnaire of self-reported stress at home and work. MAIN OUTCOMES AND MEASURES The association of stress with acute stroke and its subtypes was examined using multivariable conditional logistic regression and factors that might modify the association, particularly self-reported locus of control. RESULTS Among 26 812 participants included in the analysis, the mean (SD) age of cases was 62.2 (13.6) years; that of controls, 61.3 (13.3) years; 7960 cases (59.6%) and 8017 controls (59.6%) were men. Several periods of stress and permanent stress were reported for 2745 cases (20.5%) and 1933 controls (14.4%), with marked regional variation in prevalence, with the lowest in China (201 of 3981 [5.0%] among controls and 364 of 3980 [9.1%] among cases) and highest in South East Asia (233 of 855 [26.1%] among controls and 241 of 782 [30.8%] among cases). Increased stress at home (odds ratio [OR], 1.95 [95% CI, 1.77-2.15]) and at work (OR, 2.70 [95% CI, 2.25-3.23]) and recent stressful life events (OR, 1.31 [95% CI, 1.19-1.43]) were associated with an increased risk of acute stroke on multivariable analyses (vs no self-reported stress). Higher locus of control at home was associated with a reduced odds of all stroke (OR, 0.73 [95% CI, 0.68-0.79]), and higher locus of control both at work and at home were associated with a lower odds of acute stroke and significantly diminished the association with stress at work (OR, 2.20 [95% CI, 1.88-2.58]; P = .008 for interaction) and home (OR, 1.69 [95% CI, 1.44-1.98]; P < .001 for interaction) for acute stroke. CONCLUSIONS AND RELEVANCE Psychosocial stress is a common risk factor for acute stroke. The findings of this case-control study suggest that higher locus of control is associated with lower risk of stroke and may be an important effect modifier of the risk associated with psychosocial stress.

Abstract
PURPOSE To evaluate the association between depression/anxiety and activity limitations and health-related quality of life (HRQoL) in chronic stroke survivors in Benin. MATERIALS AND METHODS One hundred and seventy-six chronic stroke survivors (113 males; mean age (±SD): 56.5 (±10.5) years old) were included. We used the Barthel index (BI) to assess activity limitations. Participants were screened for depression and anxiety symptoms using Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale (HARS). Euroqol-5 Dimensions-3 Levels (EQ-5D-3L) including a Visual Analog Scale (EQ-VAS) was used to assess HRQoL. Multivariate linear regressions were performed to determine the impact of psychological disorders on activity limitations and HRQoL. RESULTS Depression (β=-0.54; p < 0.0001) and anxiety (β=-0.35; p < 0.0001) were negatively associated with activity limitations (R2=0.60). Similar patterns of association were observed with HRQoL (β≤-0.28; p < 0.0001; R2 ≥0.40). Inversely, occupational status showed positive association with EQ-5D-3L summary index scores (β = 0.21; p = 0.015). CONCLUSIONS Depression and anxiety had a negative impact on activity limitations and HRQoL in Beninese chronic stroke survivors. This call for action to integrate psychological interventions as part of rehabilitation programs in low and middle-income countries.Implications for rehabilitationPost-stroke depression and anxiety are quite common among stroke survivors in sub-Saharan Africa.Post-stroke depression and anxiety negatively impact activities and health-related quality of life in chronic stroke survivors in sub-Saharan Africa.Managing these post-stroke psychological disorders is necessary to promote the functional recovery and social reintegration of stroke survivors in their communities.

Abstract
OBJECTIVE This study aimed to examine the impact of different dietary patterns on stroke outcomes among type 2 diabetes mellitus (T2DM) patients in China. DESIGN Participants were enrolled by a stratified random cluster sampling method in the study. After collecting dietary data using a quantified food frequency questionnaire, latent class analysis was used to identify dietary patterns, and propensity score matching was used to reduce confounding effects between different dietary patterns. Binary logistic regression and conditional logistic regression were used to analyze the relationship between dietary patterns and stroke in patients with T2DM. SETTING A cross-sectional survey available from December 2013 to January 2014. PARTICIPANTS A total of 13731 Chinese residents aged 18 years or over. RESULTS Two dietary patterns were identified: 61.2% of T2DM patients were categorized in the High-fat dietary pattern while 38.8% of patients were characterized by the Balanced dietary pattern. Compared to the High-fat dietary pattern, the Balanced dietary pattern was associated with reduced stroke risk (OR=0.63, 95%CI: 0.52-0.76, P<0.001) after adjusting for confounding factors. The protective effect of the balanced model did not differ significantly (interaction P>0.05). CONCLUSION This study provides sufficient evidence to support the dietary intervention strategies to prevent stroke effectively. Maintaining a Balanced dietary pattern, especially with moderate consumption of foods rich in quality protein and fresh vegetables in T2DM patients, might decrease the risk of stroke in China.

Sarfo FS, Ovbiagele B. Key determinants of long-term post-stroke mortality in Ghana. J Neurol Sci 2022; 434:120123. [PMID: 34974202 PMCID: PMC8979649 DOI: 10.1016/j.jns.2021.120123] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 12/14/2021] [Accepted: 12/23/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Stroke affects a predominantly young to middle-aged population in Africa and is associated with poor outcomes. There are limited data on patient-level determinants of long-term stroke survival on the continent. PURPOSE To assess factors associated with long-term, all-cause mortality among stroke survivors in a Ghanaian medical system. METHODS We analyzed the dataset of clinical trial involving hypertensive stroke survivors (n = 60) who enrolled in a 9-month study primarily assessing the effect of an m-health intervention on blood pressure control. This was a single tertiary center study conducted in a Ghanaian medical center. Participants or relatives were contacted by a phone call to assess vital status 4.5 years after stroke onset. Demographic, psycho-social and vascular risk factors data were collected during the study. Cox proportional hazards regression modeling was used to assess the factors associated with death. RESULTS Among the study participants, long term information was obtainable on 58 of 60 (97%). After a median follow-up of 52 months [IQR: 48 to 53 months], 16 participants had died, resulting in a mortality rate of 27.6% (95% CI of 16.6% - 40.9%). Upon adjustment for confounders, the two factors independently associated with long-term mortality were resistant hypertension (Hazard Ratio 3.99; 95% CI: 1.29-12.37] and depression (Hazard Ratio 1.18; 95% CI: 1.05-1.31; per unit rise on the Hamilton Depression Scale). CONCLUSION In this convenience sample of recent stroke patients in Ghana, over a quarter had died within 5 years of index stroke onset. Resistant hypertension and depression may be modifiable therapeutic targets to improve outcomes in these patients.

Abstract
Global and local (“glocal”) disparities in stroke incidence, prevalence, care, and mortality are persistent, pervasive, and progressive. In particular, the disproportionate burden of stroke in people of African ancestry compared to most other racial/ethnic groups around the world has been long standing, is expected to worsen, and so far, has defied solution, largely because conventional risk factors likely account for less than half of the Black versus White disparity in stroke outcomes. While hypotheses such as a differential impact or inadequate evaluation of traditional risk factors by race have been suggested as potentially key factors contributing to lingering racial/ethnic stroke disparities, relatively understudied novel risk factors such as psychosocial stress, environmental pollution, and inflammation; and influences of the social determinants of health are gaining the most attention (and momentum). Moreover, it is increasingly recognized that while there is a lot still to understand, there needs to be a major shift from incessantly studying the problem, to developing interventions to resolve it. Resolution will likely require targeting multilevel factors, considering contemporaneous cross-national and cross-continental data collection, creating scalable care delivery models, jointly addressing care quality and community drivers of stroke occurrence, incorporating policy makers in planning/dissemination of successful interventions, and investing in robust transdisciplinary research training programs that address the interrelated issues of health equity and workforce diversity, and regional capacity building. To this end, our international multidisciplinary team has been involved in conducting several epidemiological studies and clinical trials in the area of stroke disparities, as well as executing career enhancing research training programs in the United States and Africa. This award lecture paper shares some of the lessons we have learnt from previous studies, presents objectives/design of ongoing initiatives, and discusses plans for the future.

The Relative Contribution of Plasma Homocysteine Levels vs. Traditional Risk Factors to the First Stroke: A Nested Case-Control Study in Rural China. Front Med (Lausanne) 2022; 8:727418. [PMID: 35127734 PMCID: PMC8811122 DOI: 10.3389/fmed.2021.727418] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Accepted: 12/07/2021] [Indexed: 11/13/2022] Open
Abstract
BackgroundApproximately 75% of Chinese hypertensive patients have elevated homocysteine (Hcy). Its implication in risk assessment and prevention of the first stroke remains an important clinical and public health question.MethodsThis study was based on a community cohort recruited from 2016 to 2018 in the rural China. To maximize cost efficiency, we used a nested case-control design, including 3,533 first stroke cases and 3,533 controls matched for age ±1 years, sex, and village. Individual associations of tHcy and traditional risk factors with the first stroke were examined, and their population-attributable risks (PARs) were estimated.ResultsThere was a significant dose-response association between first stroke and total Hcy (tHcy) levels, with adjusted odds ratios of 1.11 (95% CI: 0.97, 1.26) for tHcy 10–15 μmol/L and 1.44 (1.22, 1.69) for tHcy ≥ 15 μmol/L, all compared to tHcy < 10 μmol/L. A similar trend was found for ischemic and hemorrhagic stroke. tHcy and systolic blood pressure (SBP) were independently and additively associated with the risk of first stroke (tHcy: 1.06 [1.02, 1.1]; SBP: 1.13 [1.1, 1.16]; P-interaction, 0.889). Among the ten main risk factors examined, the top two contributors to the first stroke were SBP and tHcy, with PARs of 25.73 and 11.24%, respectively.ConclusionsElevated tHcy is the second most important contributor and acts additively with SBP to increase the risk of the first stroke. This finding underscores the importance of screening and treating elevated tHcy along with traditional risk factors to further reduce the burden of the first stroke in the high-risk populations.

Abstract
BACKGROUND Post-stroke seizures (PSS) are associated with significant morbidity and mortality across the globe. There is a paucity of data on PSS in Africa. PURPOSE To assess the frequency and factors associated with PSS by stroke types across 15 hospitals in Nigeria and Ghana. METHODS We analyzed data on all stroke cases recruited into the Stroke Investigative Research and Educational Network (SIREN). We included adults aged ≥18 years with radiologically confirmed ischemic stroke (IS) or intracerebral hemorrhage (ICH). PSS were defined as acute symptomatic seizures occurring at stroke onset and/or during acute hospitalization up until discharge. We used logistic regression to estimate adjusted odds ratios (aOR) with 95% Confidence Interval. RESULTS Among 3344 stroke patients, 499 (14.9%) had PSS (95% CI: 13.7-16.2%). The mean duration of admission in days for those with PSS vs no PSS was 17.4 ± 28.6 vs 15.9 ± 24.7, p = 0.72. There were 294(14.1%) PSS among 2091 ischemic strokes and 159(17.7%) among 897 with ICH, p = 0.01. The factors associated with PSS occurrence were age < 50 years, aOR of 1.59 (1.08-2.33), National Institute of Health Stroke Score (NIHSS), 1.29 (1.16-1.42) for each 5 units rise and white cell count 1.07 (1.01-1.13) for each 10^3 mm3 rise. Factors associated with PSS in ischemic were NIHSS score, aOR of 1.17 (1.04-1.31) and infarct volume of 10-30 cm3 aOR of 2.17(1.37-3.45). Among ICH, associated factors were alcohol use 5.91 (2.11-16.55) and lobar bleeds 2.22 (1.03-4.82). CONCLUSION The burden of PSS among this sample of west Africans is substantial and may contribute to poor outcomes of stroke in this region. Further longitudinal studies are required to understand the impact on morbidity and mortality arising from PSS in Africa.

Abstract
Background With a rising age of its population, sub-Saharan Africa(SSA) is currently experiencing an unprecedented rise in burden of neurological disorders. There is limited data on the demographic profile of neurological diseases in SSA. Objective To describe the spectrum of neurological disorders at the adult neurology clinic at Ghana's leading medical center. Methods This retrospective study was conducted at the adult neurology clinic at the Korle Bu Teaching Hospital between 2003 and 2019. We retrospectively reviewed charts of all cases seen at the clinic over the period to document main neurological diagnosis, and captured age and sex of participants. Neurologic diseases were classified using the revised International Statistical Classification of Diseases and Related Health Problems ICD 11 tool. Results There were 7950 patients sought consultation over the period with 7076 having a primary neurological disorder. The mean age ± SD of patients included in the analysis was 43.0 ± 19.8 years with 3777 (53.4%) being males. The frequencies of the top 5 neurological disorders were epilepsy (23.0%), peripheral neuropathies (19.6%), movement disorders (14.7%), cerebrovascular diseases (11.1%) and headache disorders (7.7%). Neurocognitive disorders, autoimmune demyelinating disorders of the nervous system, and motor neuron disorders were infrequently observed. Conclusion A wide spectrum of neurological disorders were encountered in this clinic, similar to previous report from other centers in SSA. There is an urgent need to build local capacity to provide optimal care to meet the demand of the rising burden of neurological diseases in Ghana.

Abstract
Hypertension is one of the most important risk factors for stroke and cardiovascular diseases (CVD) globally. Understanding risk factors for hypertension among individuals with matching characteristics with stroke patients may inform primordial/primary prevention of hypertension and stroke among them. This study identified the risk factors for hypertension among community-dwelling stroke-free population in Ghana and Nigeria. Data for 4267 community-dwelling stroke-free controls subjects in the Stroke Investigative Research and Education Network (SIREN) study in Nigeria and Ghana were used. Participants were comprehensively assessed for sociodemographic, lifestyle and metabolic factors using standard methods. Hypertension was defined as a previous diagnosis by a health professional or use of an anti-hypertensive drug or mean systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Logistic regression analysis was used to estimate adjusted odds ratios (aOR) of hypertension and their 95% confidence intervals (CI) at p < .05. Overall, 56.7% of the participants were hypertensive with a higher proportion among respondents aged ≥60 years (53.0%). Factors including physical inactivity (aOR: 9.09; 95% CI: 4.03 to 20.53, p < .0001), diabetes (aOR: 2.70; CI: 1.91 to 3.82, p < .0001), being ≥60 years (aOR: 2.22; 95% CI: 1.78 to 2.77, p < .0001), and family history of CVD (aOR 2.02; CI: 1.59 to 2.56, p < .0001) were associated with increased aOR of hypertension. Lifestyle factors were associated with hypertension in the current population of community-dwelling stroke-free controls in west Africa. Community-oriented interventions to address sedentary lifestyles may benefit this population and reduce/prevent hypertension and stroke among them.

Abstract
BACKGROUND Acute infections have been posited as potential precipitants or triggers of the occurrence of stroke among adults with traditional vascular risk factors. We evaluated associations between stroke occurrence and reported febrile illness within 4 weeks (potential antecedent infections) among West Africans. METHODS The Stroke Investigative Research and Educational Network (SIREN) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with radiologically confirmed strokes. Controls were stroke-free adults matched with cased by age, gender and ethnicity. Detailed evaluations for vascular, lifestyle and psychosocial factors were performed. Participants were asked for evidence of any febrile illness within the past 4 weeks. We used conditional logistic regression to estimate adjusted odds ratios (aOR) with 95% Confidence Interval. RESULTS Among 3588 stroke cases recruited in Ghana and Nigeria between August 2014 and July 2018, 363 cases (10.1%) reported having a febrile illness within the 4 weeks prior to stroke occurrence. Having an antecedent infection was associated with stroke occurrence with an unadjusted OR of 1.19 (1.00-1.51) but aOR of 0.83 (0.59-1.17) upon adjusting for traditional vascular risk factors. Stress, aOR of 4.69 (2.59-8.50) and consumption of green vegetables 2.27 (1.35-2.85) were associated with antecedent febrile illness. CONCLUSION 1 in 10 stroke cases reported antecedent history of febrile illness prior to occurrence of stroke but no independent association was observed in this study. Infectious exposures may be important triggers of cardiovascular events requiring further exploratory studies to better understand the role of this emerging risk factor.

Risk factors, clinical outcomes and predictors of stroke mortality in Sierra Leoneans: A retrospective hospital cohort study. Ann Med Surg (Lond) 2020; 60:293-300. [PMID: 33204420 PMCID: PMC7649580 DOI: 10.1016/j.amsu.2020.10.060] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 10/25/2020] [Accepted: 10/25/2020] [Indexed: 12/17/2022] Open
Abstract
Background Stroke data from Sierra Leone is limited, despite the increase in global burden of the disease. The aim of this study was to assess the risk factors, clinical outcomes and predictors of stroke mortality at a tertiary hospital in Freetown, Sierra Leone. Methods This retrospective cohort study was conducted on stroke patients admitted at the Connaught Teaching Hospital between 1st January to December 31, 2018. Clinical data related to stroke, with variables including patients’ demographics, stroke subtype, vascular risk factors, modified Rankin Scale (mRS), and outcomes were documented. In-hospital mortality, associated risk factors and predictors of stroke were determined. The study was approved by the Sierra Leone Ethics and Scientific Review Committee. It was registered under Research Registry https://www.researchregistry.com/browse-the-registry#home/with the unique identifying number researchregistry6009. Result We studied 178 (95 male and 83 female) patients. The mean age was 59.8 ± 14.0 years, median was 58.1years (ranging: 29–88 years). The commonest risk factors were hypertension (84.3%), tobacco smoking (35.9%) and alcohol (31.4%). Ischemic stroke confirmed by CT scan was 76.3%. In-hospital mortality was 34.8% and at discharge, mean modified Rankin Score (mRS) was 3.89 ± 1.62. The independent predictors for stroke mortality were: hypertension [AOR = 2.2; C.I 95%: (1.32–3.80), p = 0.001], previous stroke [AOR = 2.31; C.I 95%: (1.43–5.74), p = 0.001], GCS < 8 [AOR = 6.06; C.I 95%: (3.17–12.79), p < 0.001], clinical diagnosis in the absence of imaging [AOR = 3.11; C.I 95%: (2.1–9.87), p = 0.001], hemorrhagic stroke [AOR = 2.96; C.I 95%: (1.96–9.54), p < 0.001], and aspiration pneumonia [(AOR = 3.03; C.I 95%:(1.44–6.36), p = 0.001]. Women had poorer outcome than men. Conclusion This study highlights a high stroke mortality in a resource limited hospital, with some stroke patients having difficulties in accessing Computer Tomogram (CT) scan services. It illustrates the need to establish a stroke care setting to improve the quality of stroke care. Globally, sub-Saharan Africa (SSA) has the highest incidence and case-fatality from stroke. In Sierra Leone, the dearth of stroke data limits the access to evidence-based standards of stroke care. We reported a high in-hospital stroke mortality, with majority of the deaths occurring in the first week, and this is comparable to some reported studies from SSA. The poor control of hypertension and aspiration pneumonia are major but avoidable contributors to poor stroke outcomes in SSA.

Abstract
BACKGROUND Post-stroke epilepsy (PSE) is associated with poorer quality of life, higher mortality, and greater health expenditures. We are unaware of any published reports on the frequency of and factors associated with PSE in Africa. PURPOSE To assess the frequency and factors associated with PSE among Ghanaian stroke survivors. METHODS We conducted a cross-sectional study of consecutive stroke survivors seen at an out-patient Neurology clinic enrolled into a stroke registry at a tertiary medical center in Ghana between January 2018 and March 2020. We collected baseline demographic and clinical details including diagnosis of post-stroke epilepsy, anti-epileptic medications, presence, treatment and control of vascular risk factors. Multivariate logistic regression models were constructed to identify factors associated with PSE. RESULTS Of 1101 stroke patients encountered, 126 had PSE (frequency of 11.4%; 95% CI of 9.6-13.5%). Mean (± SD) age among PSE vs. non-PSE patients was 57.7 (± 15.2) vs. 58.7 (± 13.9) years. Factors independently associated with PSE were being male (aOR 1.94; 95% CI: 1.32-2.86), cortical ischemic strokes (1.79; 1.12-2.87), blood pressure > 130/80 mmHg (OR 2.26; 1.06-4.79), use of antihypertensive treatment (OR 0.43; 0.23-0.79). There was an inverted J-shaped curve association between number of classes of antihypertensive drugs prescribed and occurrence of PSE, with the lowest inflection point at 3 classes (OR 0.34; 0.17-0.68). CONCLUSION In this convenience sample of ambulatory Ghanaian stroke survivors, one in ten had PSE. Further investigations to confirm and clarify the associations between the identified demographic and clinical characteristics are warranted.

Abstract
BACKGROUND Clinical trial data indicate that more intensive blood pressure (BP) lowering below standard cut-off targets is associated with lower risks of strokes in the elderly. There is a relative paucity of real-world practice data on this issue, especially among Africans. OBJECTIVE To assess BP control rates, its determinants, and whether a lower BP < 120/80 mmHg is associated with a lower incident stroke risk among elderly Ghanaians with hypertension. METHODS We retrospectively evaluated data, which were prospectively collected as part of a cohort study involving adults with hypertension and/or diabetes in 5 Ghanaian hospitals. BP control was defined using the JNC-8 guideline of <150/90 mmHg for elderly with hypertension aged >60 years or 140/90 mmHg for those with diabetes mellitus. Risk factors for poor BP control were assessed using multivariable logistic regression models. We calculated incident stroke risk over an 18-month follow-up at 3 BP cut-off's of <120/80, 120-159/80-99, and > 160/100 mmHg. RESULTS Of the 1365 elderly participants with hypertension, 38.2% had diabetes mellitus and 45.8% had uncontrolled BP overall. Factors associated with uncontrolled BP were higher number of antihypertensive medications prescribed adjusted odds ratio of 1.45 (95% CI: 1.27-1.66), and having diabetes 2.56 (1.99-3.28). Among the elderly, there were 0 stroke events/100py for BP < 120/80 mmHg, 1.98 (95%CI: 1.26-2.98) for BP between 120 and 159/80-99 mmHg and 2.46 events/100py (95% CI: 1.20-4.52 at BP > 160/100 mmHg. CONCLUSION A lower BP target <120/80 mmHg among elderly Ghanaians with hypertension is associated with a signal of lower incident stroke risk. Pragmatic trials are needed to evaluate lower BP targets on stroke incidence in Africa.

Abstract
BACKGROUND Refractory hypertension (RfH) is a rare, severe phenotype of resistant hypertension, linked to higher risk of adverse cardiovascular outcomes. Little is known about the association of RfH with stroke type and subtype. OBJECTIVE To determine the prevalence and predictors of RfH among stroke survivors in Ghana. METHODS We interrogated the dataset of a prospectively collected registry of hypertensive patients seen between July 2015 and June 2019, at five hospitals in Ghana. We compared stroke survivors to stroke-free controls. Clinic-based blood pressure was measured using a standardized protocol and antihypertensive medications were assessed via review of medical records and inspection of pills. Refractory hypertension was defined as office BP ≥140/90 mmHg on ≥5 classes of antihypertensive medications. Multivariate logistic regression models were constructed to assess factors associated with RfH. RESULTS Of 3927 hypertensive patients (1169 stroke survivors, 2758 controls), 86 had RfH for an overall prevalence of 2.2% (95% CI: 1.8-2.7%). Among patients with RfH, 5.8% (4.5-7.3%) were stroke survivors vs. 0.7% (0.4-1.0%) were stroke-free (p < .0001). Adjusted odds ratio (95% CI) for factors associated with RfH were being male (1.81, 1.15-2.85), age < 60 years (2.64, 1.59-4.40), chronic kidney disease (2.09, 1.21-3.60), and known stroke (7.53, 4.35-13.04). RfH was associated with intracerebral hemorrhage, (11.43, 5.65-23.14), ischemic stroke (9.76, 5.47-17.42), lacunar stroke (13.58, 6.45-28.61), and non-lacunar ischemic stroke (3.67, 1.04-13.02). CONCLUSION Presence of RfH is significantly accentuated among stroke survivors. Intensified efforts are warranted to identify and aggressively address barriers to control in these patients to avert subsequent vascular events.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17103583.

Abstract
Background: Cardiovascular diseases (CVDs) are part of the leading causes of mortality and morbidity in developing countries, including South Africa, where they are a major public health issue. Understanding the joint spatial clustering of CVDs and associated risk factors to determine areas in need of enhanced integrated interventions would help develop targeted, cost-effective and productive mediations. We estimated joint spatial associations and clustering patterns of 2 CVDs (stroke and heart attack) and 3 risk factors (hypertension, high blood cholesterol (HBC) and smoking) among adults in South Africa. Methods: We used cross-sectional secondary adult (15–64-year olds) health data from the South African Demographic Health Survey 2016. Age and gender standardized disease incidence ratios were analyzed using joint spatial global and local bivariate Moran’s Index statistics. Results: We found significantly positive univariate spatial clustering for stroke (Moran; s Index = 0.128), smoking (0.606) hypertension (0.236) and high blood cholesterol (0.385). Smoking and high blood cholesterol (0.366), smoking and stroke (0.218) and stroke and high blood cholesterol (0.184) were the only bivariate outcomes with significant bivariate clustering. There was a joint stroke-smoking local “hot spots” cluster among four districts in the urban western part of the country (City of Cape Town; Cape Winelands; Overberg and Eden) and a joint “cold spots” cluster in the rural north-western part of the country. Similar joint “hot spots” clustering was found for stroke and high blood cholesterol, which also had “cold spots” cluster in the rural east-central part of the country. Smoking and high blood cholesterol had a “hot spots” cluster among five districts in the urban western part of the country (City of Cape Town; Cape Winelands; Overberg; Eden, and West Coast) and “cold spots” around the rural districts in east-southern parts of the country. Conclusions: Our study showed that districts tended to co-cluster based on the rates of CVDs and risk factors, where higher rates were found in urban places than in rural areas. These findings are suggestive of a more contagious and spatial diffusion process among interdependent districts in urban districts. Urbanization or rurality needs to be considered when intervention initiatives are implemented with more general approaches in rural areas. The finding of “hot spot” co-clusters in urban areas means that integrated intervention programmes aimed at reducing the risk of CVDs and associated risk factors would be cost-effective and more productive.

Abstract
Cognitive impairment and dementia (CID) are major public health problems with substantial personal, social, and financial burdens. African Americans are at a heightened risk for Vascular Cognitive Impairment (VCI) compared to European Americans. Recent lines of evidence also suggest a high burden of Post-stroke VCI among indigenous Africans. A better understanding of the cause(s) of the racial disparity in CID, specifically VCI, is needed in order to develop strategies to reduce it. We propose and discuss the conceptual framework for a unique tri-population, trans-continental study titled The Vascular brain Injury Progression after Stroke (VIPS) study. The overarching objective of the VIPS Study will be to explore the interplay of multiple factors (racial, geographical, vascular, lifestyle, nutritional, psychosocial and inflammatory) influencing the level and trajectory of post-stroke cognitive outcomes and examine whether differences between indigenous Africans, African Americans and European Americans exist. We hypothesize that differences which might be due to racial factors will be observed in African Americans versus European Americans as well as Indigenous Africans versus European Americans but not in African Americans versus Indigenous Americans; differences due to geographical factors will be observed in Indigenous Americans versus African Americans and Indigenous Africans versus European Americans but not in African Americans versus European Americans. This overarching objective could be accomplished by building upon existing National Institutes of Health investments in the REasons for Geographical And Racial Differences in Stroke (REGARDS) study (based in the United States of America) and the Stroke Investigative Research and educational Network (SIREN) study (based in Sub-Saharan Africa).

Abstract
BACKGROUND Inadequate implementation of evidence-based preventive measures for individuals at high risk of cardiovascular disease (CVD) will only worsen the current epidemic of CVDs in sub-Saharan Africa. We assessed rates and predictors of statin utilization among two high CVD risk patient populations, people with type 2 diabetes mellitus (T2DM) and those with stroke, encountered across five hospitals in Ghana. METHODS A cross-sectional study among 1427 patients with T2DM and 159 stroke survivors encountered at 5 hospitals (1 primary-level, 2 secondary level and 2 tertiary level) in Ghana between July 2015 and June 2018. We collected baseline demographic and clinical details including statin prescription from medical records. Factors associated with statin prescription among T2DM for primary prevention and stroke survivors for secondary prevention were evaluated using multivariate logistic regression analysis. RESULTS Among patients with T2DM without CVDs, 240 (16.8%) were on statins for primary prevention. Factors associated with statin use among diabetics expressed as aOR (95% CI) were being treated at a tertiary level hospital 5.86 (3.22-10.68), hypertension comorbidity 1.80 (1.25-2.60), and lower income 0.43 (0.26-0.70). Among 159 stroke survivors, 22 (14.0%) were on statins with the following associated factors: lower income 0.16 (0.03-0.77), secondary level vs. tertiary level education 0.21 (0.05-0.97) and having T2DM 4.69 (1.63-13.49). CONCLUSION Approximately 1 in 6 individuals with T2DM without CVD and 1 in 7 stroke survivors are prescribed statins in Ghana. Efforts to bridge this practice gap and improve access to life saving preventative medications for CVD risk reduction in low-and-middle income countries are urgently warranted.

Abstract
Background Reports on sex differences in stroke outcome and risk factors are scarce in Latin America. Our objective was to analyze clinical and prognostic differences according to sex among participants in the LASE (Latin American Stroke Registry). Methods and Results Nineteen centers across Central and South America compiled data on demographics, vascular risk factors, clinical stroke description, ancillary tests, and functional outcomes at short‐term follow‐up of patients included from January 2012 to January 2017. For the present study, all these variables were analyzed according to sex at hospital discharge. We included 4788 patients with a median in‐hospital stay of 8 days (interquartile range, 5–8); 2677 were male (median age, 66 years) and 2111 female (median age, 60 years). Ischemic stroke occurred in 4293: 3686 as cerebral infarction (77%) and 607 as transient ischemic attack cases (12.7%); 495 patients (10.3%) corresponded to intracerebral hemorrhage. Poor functional outcome (modified Rankin scale, 3–6) was present in 1662 (34.7%) patients and 38.2% of women (P<0.001). Mortality was present in 6.8% of the registry, with 7.8% in women compared with 6.0% in men (P=0.01). Death and poor functional outcome for all‐type stroke showed a higher risk in female patients (hazard ratio, 1.3, P=0.03; and hazard ratio, 1.1, P=0.001, respectively). Conclusions A worse functional outcome and higher mortality rates occurred in women compared with men in the LASE, confirming sex differences issues at short‐term follow‐up.
