[PMID: 38663647 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/17/2024] [Accepted: 04/22/2024] [Indexed: 05/24/2024] Open
Abstract
BACKGROUND With approximately 11 million strokes occurring annually worldwide, and over 6.5 million deaths annually, stroke has made its place as one of the major killers in the world. Although developing countries make up more than 4/5 of the global stroke burden, well-grounded information on stroke epidemiology remains lacking there. AIMS This systematic review study aimed to provide a synthesis of studies on the incidence and prevalence of stroke among adults in sub-Saharan Africa (SSA), subsequently deduce the associated risk factors and public health implications (mortality rates and economic costs) of the disease on the population of this region. METHODS A systematic review of studies carried out in the region and published on PUBMED. Eligibility criteria were established using the PEO (Population/Patient, Exposure, Outcome) format. Research articles investigating either (or all) of the following: ischemic or haemorrhagic stroke, incidence, prevalence, and risk factors of stroke in adults (≥ 18 years old), in at least one region of SSA were included. Exclusion criteria comprised studies involving populations younger than 18 years old, research conducted outside the designated research region, and articles inaccessible in full text. The PRISMA guidelines were used for the search strategy. RESULTS Fifty-two studies were included review. Among them, over 11 studies investigated the prevalence of the disease. Some older studies within the continent (Nigeria, 2011) showed a prevalence of 1.3 per 100 while more recent studies (Zambia, 2021) showed a prevalence of 4.3 per 1000. The highest prevalence noted in this region was in Madagascar (2017) with 48.17 per 100, while the lowest was recorded in (Zimbabwe, 2017) with 0.61 per 100. The study in Tanzania showed a crude incidence of 94·5 per 100 000 (76·0-115·0) while the study in Ghana in 2018 showed an incidence of 14.19 events per 1000 person-years [10.77-18.38]. The identified risk factors included hypertension, diabetes, smoking, alcohol consumption, physical inactivity, poor diets (more salt, less vegetables), dyslipidaemia, HIV/AIDS co-infection, heart disease (cardiomyopathies, cardiac arrhythmias), obesity, previous stroke and/or family history of stroke. Over 21 studies investigated the mortality rates due to stroke in SSA, with most of the studies being in West Africa. These studies revealed mortality rates as high as 43.3% in Ghana, and as low as 10.9% in Cameroon. Few studies reported on the economic costs of stroke in the region; two in Benin, two in Nigeria and one in Tanzania. CONCLUSION The increasing incidence/prevalence, lifestyle factors and interactions with other diseases, including major communicable diseases, stroke is becoming a pressing public health problem for SSA. Reducing the incidence of stroke in Africa will surely lower mortality, morbidity, disability, and the neurological as well as cognitive aftereffects of stroke, as is clear from the experience of higher-income nations. We recommend a collective intervention involving the governments of nations, international organizations, civil society, and the private sector for greater impact and sustainable outcomes reducing the epidemiology and implications of stroke in SSA.

Abstract
Stroke is the second leading cause of death and the third leading cause of disability worldwide. Though the burden of stroke worldwide seems to have declined in the past three decades, much of this effect reflects decreases in high-income countries (HICs). By contrast, the burden of stroke has grown rapidly in low-income and middle-income countries (LMICs), where epidemiological, socioeconomic and demographic shifts have increased the incidence of stroke and other non-communicable diseases. Furthermore, even in HICs, disparities in stroke epidemiology exist along racial, ethnic, socioeconomic and geographical lines. In this Review, we highlight the under-acknowledged disparities in the burden of stroke. We emphasize the shifting global landscape of stroke risk factors, critical gaps in stroke service delivery, and the need for a more granular analysis of the burden of stroke within and between LMICs and HICs to guide context-appropriate capacity-building. Finally, we review strategies for addressing key inequalities in stroke epidemiology, including improvements in epidemiological surveillance and context-specific research efforts in under-resourced regions, development of the global workforce of stroke care providers, expansion of access to preventive and treatment services through mobile and telehealth platforms, and scaling up of evidence-based strategies and policies that target local, national, regional and global stroke disparities.

Abstract
OBJECTIVES Stroke is a major public health problem worldwide with disparities between urban and rural areas. The aim of this study was to compare the epidemiological, clinical features and outcomes of stroke between rural and urban hospitals in Cameroon. MATERIALS AND METHODS We conducted a retrospective cohort study at the Douala General Hospital (urban) and Ad Lucem Hospital of Banka (rural) from January 1st, 2014, to December 31st, 2019. The medical records of all patients admitted for stroke, and meeting the inclusion criteria were reviewed. Diagnosis of stroke was based on brain imaging and/or the World Health Organization definition. Data were analyzed using SPSS version 20.0. RESULTS Among the 15277 files reviewed, 752 were included with 623 cases (82.80%) in urban areas. The percentage of patients hospitalized for stroke were 9.06% and 2.85% in urban and rural hospitals respectively. The frequency of patients admitted for severe stroke (Glasgow coma scale ≤ 8) was higher in the rural hospital (p = 0.004). In-hospital mortality (p = 0.010), cumulative mortality at one-month (p = 0.018), poor functional recovery (p = 0.002), one-year stroke recurrence (p = 0.020) were significantly higher in rural setting. Undefined stroke was predictor of mortality in the rural hospital, while hemorrhagic stroke was predictor of mortality at one-month in the urban hospital. CONCLUSIONS Stroke cases were significantly more severe with poor outcomes in the rural hospital. Efforts are needed to improve prevention, and access to stroke care for communities, especially in rural setting.

[PMID: 37827183 PMCID: PMC10715732 DOI: 10.1016/s1474-4422(23)00277-6] [Citation(s) in RCA: 48] [Impact Index Per Article: 48.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 07/14/2023] [Indexed: 10/14/2023]
Abstract
Stroke is the second leading cause of death worldwide. The burden of disability after a stroke is also large, and is increasing at a faster pace in low-income and middle-income countries than in high-income countries. Alarmingly, the incidence of stroke is increasing in young and middle-aged people (ie, age <55 years) globally. Should these trends continue, Sustainable Development Goal 3.4 (reducing the burden of stroke as part of the general target to reduce the burden of non-communicable diseases by a third by 2030) will not be met. In this Commission, we forecast the burden of stroke from 2020 to 2050. We project that stroke mortality will increase by 50%—from 6·6 million (95% uncertainty interval [UI] 6·0 million–7·1 million) in 2020, to 9·7 million (8·0 million–11·6 million) in 2050—with disability-adjusted life-years (DALYs) growing over the same period from 144·8 million (133·9 million–156·9 million) in 2020, to 189·3 million (161·8 million–224·9 million) in 2050. These projections prompted us to do a situational analysis across the four pillars of the stroke quadrangle: surveillance, prevention, acute care, and rehabilitation. We have also identified the barriers to, and facilitators for, the achievement of these four pillars. Disability-adjusted life-years (DALYs) The sum of the years of life lost as a result of premature mortality from a disease and the years lived with a disability associated with prevalent cases of the disease in a population. One DALY represents the loss of the equivalent of one year of full health On the basis of our assessment, we have identified and prioritised several recommendations. For each of the four pillars (surveillance, prevention, acute care, and rehabilitation), we propose pragmatic solutions for the implementation of evidence-based interventions to reduce the global burden of stroke. The estimated direct (ie, treatment and rehabilitation) and indirect (considering productivity loss) costs of stroke globally are in excess of US$891 billion annually. The pragmatic solutions we put forwards for urgent implementation should help to mitigate these losses, reduce the global burden of stroke, and contribute to achievement of Sustainable Development Goal 3.4, the WHO Intersectoral Global Action Plan on epilepsy and other neurological disorders (2022–2031), and the WHO Global Action Plan for prevention and control of non-communicable diseases. Reduction of the global burden of stroke, particularly in low-income and middle-income countries, by implementing primary and secondary stroke prevention strategies and evidence-based acute care and rehabilitation services is urgently required. Measures to facilitate this goal include: the establishment of a framework to monitor and assess the burden of stroke (and its risk factors) and stroke services at a national level; the implementation of integrated population-level and individual-level prevention strategies for people at any increased risk of cerebrovascular disease, with emphasis on early detection and control of hypertension; planning and delivery of acute stroke care services, including the establishment of stroke units with access to reperfusion therapies for ischaemic stroke and workforce training and capacity building (and monitoring of quality indicators for these services nationally, regionally, and globally); the promotion of interdisciplinary stroke care services, training for caregivers, and capacity building for community health workers and other health-care providers working in stroke rehabilitation; and the creation of a stroke advocacy and implementation ecosystem that includes all relevant communities, organisations, and stakeholders. The Lancet Group takes a neutral position with respect to territorial claims in published maps and institutional affiliations.

Abstract
Despite a growing burden of stroke in low-middle-income countries, research on patient's experiences and access to rehabilitation services remains limited. This study explores the experiences of stroke patients in relation to access and use of stroke rehabilitation services, coping strategies and strategies to improve care in Ghana. A cross-sectional study was conducted. A total of 136 adult stroke patients hospitalised and subsequently discharged in three major referral hospitals in Ghana participated in the study. A paper-based questionnaire was used to collect data. Data were inputted into STATA version 12, cleaned and analysed using descriptive statistics and Chi-Square tests. Findings showed that stroke patients experience stroke differently. Early detection (awareness) of stroke symptoms at onset was low (29.4%). Hypertension was the major (58.1%) predisposing risk factor for stroke, followed by diabetes (14.7%). Multiple barriers impede access to outpatient rehabilitation services: high cost of medications (43.4%), transportation constraints (10.3%), long waiting time (6.6%), forgetfulness about appointment (4.4%), limited education on rehabilitation (20.6%), lack of community support (12.5%) and ineffective communication with healthcare providers (5.2%). Recommended strategies to improve access to rehabilitation care included public education on stroke and its associated risk, reduction in the cost of drugs and increased stroke rehabilitation funding by the NHIS, especially for physiotherapy consultation and training support to caregivers on patient care. Given the difference in stroke experience and barriers in accessing rehabilitation care, multi-level health policy and service delivery reforms are needed to improve access to rehabilitation care, including national public awareness campaigns on early signs of stroke and subsidised cost of stroke rehabilitation.

Abstract
BACKGROUND In South Africa (SA), stroke is the second highest cause of mortality and disability. Apart from being the main killer and cause of disability, stroke is an expensive disease to live with. Stroke costs include death and medical costs. Little is known about the stroke burden, particularly the stroke direct costs in SA. Identification of stroke costs predictors using appropriate statistical methods can help formulate appropriate health programs and policies aimed at reducing the stroke burden. Analysis of stroke costs have in the main, concentrated on mean regression, yet modelling with quantile regression (QR) is more appropriate than using mean regression. This is because the QR provides flexibility to analyse the stroke costs predictors corresponding to quantiles of interest. This study aims to estimate stroke direct costs, identify and quantify its predictors through QR analysis. METHODS Hospital-based data from 35,730 stroke cases were retrieved from selected private and public hospitals between January 2014 and December 2018. The model used, QR provides richer information about the predictors on costs. The prevalence-based approach was used to estimate the total stroke costs. Thus, stroke direct costs were estimated by taking into account the costs of all stroke patients admitted during the study period. QR analysis was used to assess the effect of each predictor on stroke costs distribution. Quantiles of stroke direct costs, with a focus on predictors, were modelled and the impact of predictors determined. QR plots of slopes were developed to visually examine the impact of the predictors across selected quantiles. RESULTS Of the 35,730 stroke cases, 22,183 were diabetic. The estimated total direct costs over five years were R7.3 trillion, with R2.6 billion from inpatient care. The economic stroke burden was found to increase in people with hypertension, heart problems, and diabetes. The age group 55-75 years had a bigger effect on costs distribution at the lower than upper quantiles. CONCLUSIONS The identified predictors can be used to raise awareness on modifiable predictors and promote campaigns for healthy dietary choices. Modelling costs predictors using multivariate QR models could be beneficial for addressing the stroke burden in SA.

Abstract
BACKGROUND AND PURPOSE The role of community health workers (CHWs) in stroke surveillance and in establishing the stroke care pathway has not been studied. The aim of the study was to evaluate the feasibility of using CHWs in the public health system to identify stroke patients for population-based stroke registration and to study the establishment of acute stroke care pathway in rural areas of Ludhiana, Punjab, Northwest India. METHODS Two rural blocks in Ludhiana district, comprising 164 villages and a population of 259,778, were selected. Phase-1 (feasibility study) was from August to November 2016 and phase-2 from December 2016 to November 2018. All first-ever stroke cases in adults (aged ≥18 years) were included. The accredited social health activists (ASHAs) were trained to identify stroke patients in the community, who were later evaluated by a neurologist. Stroke characteristics were recorded, and the outcome was assessed at 6 months using modified Rankin scale (0-2, good outcome). FINDINGS During phase-2, 359 first-ever stroke patients and 102 stroke mimics were identified. The age-standardized incidence rate was 218.5/100,000 and 197∙6/100,000 for each year. Half (52.4%) of the patients reached health-care facilities within 4.5 h, yet none of them received thrombolysis. Very few patients (1.9%) utilized free government 108 ambulance service to reach a health-care facility. Out of 359 stroke cases, the majority (306, 85.23%) were reported by ASHAs and 14.77% were reported by other sources. Brain imaging was available in 127 (35.4%) patients, and 100 (78.7%) had ischemic stroke. The most common risk factor was hypertension (320, 89%) and drug abuse (154, 42.9%). At 6 months, 168 (64%) patients had a good outcome. CONCLUSION ASHAs were able to identify stroke patients in the villages. Despite high numbers of patients reaching health-care facilities within a window period, the hospitals were unable to provide acute stroke treatment like thrombolysis. The health-care system needs to be strengthened to improve stroke care.

Abstract
Introduction This study explored the impact of HIV on the functional recovery of personal activities of daily living of stroke survivors. This assisted in identifying possible implications for the rehabilitation of stroke survivors who are also HIV-positive. Method A quantitative, descriptive, longitudinal comparative research design was used to determine the change in personal activities of daily living scores of HIV-negative and HIV-positive stroke survivors from admission to 1 month after discharge. Data were collected at a rehabilitation unit using the South African Database Functional Measure. Results There was no difference in the rate and nature of functional recovery of personal activities of daily living between the two groups between admission and discharge. A difference was noticed during the period from admission to 1 month after discharge, during which the HIV-negative group continued to show improvement, while the HIV-positive group showed little improvement or a decline in personal activities of daily living scores. Conclusions While the rate and nature of functional recovery related to personal activities of daily living for HIV-positive and HIV-negative stroke survivors is similar during inpatient care, discharge planning for the HIV-positive group needs to consider the decline in personal activities of daily living functioning post discharge. Regular follow-ups and the inclusion of the stroke survivors in an outpatient treatment programme is recommended.

Abstract
Background Stroke is the second leading cause of death worldwide. There is limited literature detailing the clinical profile of stroke in developing countries’ emergency departments (EDs). The aim of this study is to describe the demographics and risk factors of patients presenting with stroke to an ED in South Africa. Methods This study was a retrospective chart review of all patients with a clinical diagnosis of stroke presenting to an ED of a regional hospital in rural KwaZulu-Natal from November 2018 to November 2019. Results A total of 362 patient charts were screened, and 136 of the charts met the inclusion criteria for the study. Seventy per cent of the patients had pre-existing hypertension, only one patient was not on treatment and two patients were not on secondary prevention. In human immunodeficiency virus–positive patients (20.5%; n = 28), 17 patients were under 50 years old. The most common finding on computer tomography was ischemic strokes (74%, n = 100). Thrombolysis was given to five patients included in the study. The overall in-hospital mortality rate was 4.06%. Conclusion This study adds to the limited data about stroke in South Africa. Our population represents a unique blend of infectious and lifestyle disease. More research in this setting is recommended to develop local guidelines on emergency stroke care.

Abstract
OBJECTIVE This paper explores the economic value of rehabilitation to South Africa, using a costed example of cerebrovascular accident (CVA) (stroke) rehabilitation. DESIGN We report an economic modelling approach using a worked cost-effectiveness to validate the argument for the cost-saving benefits of stroke rehabilitation. SETTING South African health care, employing analysis of available secondary data from South African research and government reports. PARTICIPANTS In line with international trends in stroke epidemiology, we focused on people who were employed prior to having their stroke, with return-to-work as the desired rehabilitation outcome. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) We used information on stroke rehabilitation and secondary data derived from grey and published literature, to determine if early stroke rehabilitation represents value for money from the government perspective. For our worked example, we used return-to-work rates, intervention costs, and the cost of rehabilitation services to estimate cost-savings as a result of an individualized workplace intervention. RESULTS The cost of delivering the individualized intervention was estimated at R5633/patient. Combining survivor rates, return-to-work rate, and costs of the programme, a work intervention programme could result in a net saving of R133.1 million over 5 years (or about R26.6 per year (discount 3%). CONCLUSION The value of rehabilitation should not be considered in terms of cost-effectiveness alone, but also as an investment for the country. A staged, prioritized approach should be considered in future South African national health budget.

[PMID: 32690019 PMCID: PMC7370468 DOI: 10.1186/s12955-020-01436-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 06/04/2020] [Indexed: 01/29/2023] Open
Abstract
Background Burden of stroke is rising due to the demographic and epidemiological transitions in Sri Lanka. Assessment of success of stroke-management requires tools to assess the quality of life (QOL) of stroke survivors. Most of currently used QOL tools are developed in high-income countries and may not reflect characteristics relevant to resource-constrained countries. The aim was to develop and validate a new QOL tool for stroke survivors in Sri Lanka. Methods The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) checklist was referred. A conceptual framework was prepared. Item generation was done reviewing the existing QOL tools, inputs from experts and from stroke survivors. Non-statistical item reduction was done for the 36 generated items with modified-Delphi technique. Retained 21 items were included in the draft tool. A cross sectional study was done with 180 stroke survivors. Exploratory Factor Analysis was done and identified factors were subjected to varimax rotation. Further construct validity was tested with 6 a-priori hypothesis using already validated tools (SF-36, EQ-5D-3 L) and a formed construct. Internal consistency reliability was assessed with Cronbach alpha. Results Four factors identified with principal-component-analysis explained 72.02% of the total variance. All 21 items loaded with a level > 0.4. The developed tool was named as the Post-stroke QOL Index (PQOLI). Four domains were named as “physical and social function”, “environment”, “financial-independence” and “pain and emotional-wellbeing”. Four domain scores of PQOLI correlated as expected with the SF-36, EQ-5D Index and EQ-5D-VAS scores. Higher domain scores were obtained for ambulatory-group than the hospitalized-group. Higher scores for financial-independence domain were obtained for the group without financial-instability. Five a-priori hypothesis were completely proven to be true. Cronbach-alpha level ranged from 0.682 to 0.906 for the four domains. Conclusions There is first evidence for sufficient construct validity of the PQOLI as a valid QOL tool for measuring the QOL of stroke survivors with satisfactory internal consistency reliability.

Abstract
BACKGROUND Data on stroke epidemiology and availability of hospital-based stroke services around the world are important for guiding policy decisions and healthcare planning. AIMS To provide the most current incidence, mortality and case-fatality data on stroke and describe current availability of stroke units around the world by country. METHODS We searched multiple databases (based on our existing search strategy) to identify new original manuscripts and review articles published between 1 June 2016 and 31 October 2018 that met the ideal criteria for data on stroke incidence and case-fatality. For data on the availability of hospital-based stroke services, we searched PubMed for all literature published up until 31 June 2018. We further screened reference lists, citation history of manuscripts and gray literature for this information. Mortality codes for International Classification of Diseases-9 and International Classification of Diseases-10 were extracted from the World Health Organization mortality database for each country providing these data. Population denominators were obtained from the World Health Organization, and when these were unavailable within a two-year period of mortality data, population denominators within a two-year period were obtained from the United Nations. Using country-specific population denominators and the most recent years of mortality data available for each country, we calculated both the crude mortality from stroke and mortality adjusted to the World Health Organization world population. RESULTS Since our last report in 2017, there were two countries with new incidence studies, China (n = 1) and India (n = 2) that met the ideal criteria. New data on case-fatality were found for Estonia and India. The most current mortality data were available for the year 2015 (39 countries), 2016 (43 countries), and 2017 (7 countries). No new data on mortality were available for six countries. Availability of stroke units was noted for 63 countries, and the proportion of patients treated in stroke units was reported for 35/63 countries. CONCLUSION Up-to-date data on stroke incidence, case-fatality, and mortality statistics provide evidence of variation among countries and changing magnitudes of burden among high and low-middle income countries. Reporting of hospital-based stroke units remains limited and should be encouraged.

Abstract
Rehabilitation training is believed to be beneficial to patients with stroke, but its molecular mechanism is still unclear. Rat models of cerebral ischemic stroke were established by middle cerebral artery occlusion/reperfusion, and then received treadmill training of different intensities, twice a day for 30 minutes for 1 week. Low-intensity training was conducted at 5 m/min, with a 10-minute running, 10-minute rest, and 10-minute running cycle. In the moderate-intensity training, the intensity gradually increased from 5 m/min to 10 m/min in 5 minutes, with the same rest cycle as above. In high-intensity training, the intensity gradually increased from 5 m/min to 25 m/min in 5 minutes, with the same rest cycle as above. The Bederson scale was used to evaluate the improvement of motor function. Infarct volume was detected using 2,3,5-triphenyltetrazolium chloride staining. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining was applied to detect the apoptosis of nerve cells in brain tissue. Western blot assay was employed to analyze the activation of cyclic adenosine monophosphate (cAMP)/protein kinase A and Akt/glycogen synthase kinase-3β signaling pathways in rat brain tissue. All training intensities reduced the neurological deficit score, infarct volume, and apoptosis in nerve cells in brain tissue of stroke rats. Training intensities activated the cAMP/protein kinase A and Akt/glycogen synthase kinase-3 beta signaling pathways. This activation was more obvious with higher training intensities. These changes were reversed by intracerebroventricular injection of protein kinase A inhibitor Rp-cAMP. Our findings indicate that the neuroprotective effect of rehabilitation training is achieved via activation of the cAMP/protein kinase A and Akt/glycogen synthase kinase-3 beta signaling pathways. This study was approved by the Ethics Committee of Animal Experimentation in Shanghai No. 8 People’s Hospital, China.

Andrews M, Pillay M. Poor consistency in evaluating South African adults with neurogenic dysphagia. SOUTH AFRICAN JOURNAL OF COMMUNICATION DISORDERS 2017; 64:e1-e14. [PMID: 28155280 PMCID: PMC5842977 DOI: 10.4102/sajcd.v64i1.158] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2016] [Revised: 07/21/2016] [Accepted: 09/11/2016] [Indexed: 11/01/2022] Open
Abstract
BACKGROUND Speech-language therapists are specifically trained in clinically evaluating swallowing in adults with acute stroke. Incidence of dysphagia following acute stroke is high in South Africa, and health implications can be fatal, making optimal management of this patient population crucial. However, despite training and guidelines for best practice in clinically evaluating swallowing in adults with acute stroke, there are low levels of consistency in these practice patterns. OBJECTIVE The aim was to explore the clinical practice activities of speech-language therapists in the clinical evaluation of swallowing in adults with acute stroke. Practice activities reviewed included the use and consistency of clinical components and resources utilised. Clinical components were the individual elements evaluated in the clinical evaluation of swallowing (e.g. lip seal, vocal quality, etc.)Methods: The questionnaire used in the study was replicated and adapted from a study increasing content- and criterion-related validity. A narrative literature review determined what practice patterns existed in the clinical evaluation of swallowing in adults. A pilot study was conducted to increase validity and reliability. Purposive sampling was used by sending a self-administered, electronic questionnaire to members of the South African Speech-Language-Hearing Association. Thirty-eight participants took part in the study. Descriptive statistics were used to analyse the data and the small qualitative component was subjected to textual analysis. RESULTS There was high frequency of use of 41% of the clinical components in more than 90% of participants (n = 38). Less than 50% of participants frequently assessed sensory function and gag reflex and used pulse oximetry, cervical auscultation and indirect laryngoscopy. Approximately a third of participants showed high (30.8%), moderate (35.9%) and poor (33.3%) consistency of practice each. Nurses, food and liquids and medical consumables were used usually and always by more than 90% of participants. CONCLUSION Infrequent use of clinical components and high variability in clinical practice among speech-language therapists calls for uniform curricula in the clinical evaluation of swallowing at South African universities and for continued professional development post-graduation. Different contexts and patient symptoms contribute towards varied practice; however, there is still a need to improve consistency of practice for quality health care delivery. A research-based policy for the clinical swallowing evaluation for a resource-limited context is also needed.

Abstract
Background Up to date data on incidence, mortality, and case-fatality for stroke are important for setting the agenda for prevention and healthcare. Aims and/or hypothesis We aim to update the most current incidence and mortality data on stroke available by country, and to expand the scope to case-fatality and explore how registry data might be complementary. Methods Data were compiled using two approaches: (1) an updated literature review building from our previous review and (2) direct acquisition and analysis of stroke events in the World Health Organization (WHO) mortality database for each country providing these data. To assess new and/or updated data on incidence, we searched multiple databases to identify new original papers and review articles that met ideal criteria for stroke incidence studies and were published between 15 May 2013 and 31 May 2016. For data on case-fatality, we searched between 1980 and 31 May 2016. We further screened reference lists and citation history of papers to identify other studies not obtained from these sources. Mortality codes for ICD-8, ICD-9, and ICD-10 were extracted. Using population denominators provided for each country, we calculated both the crude mortality from stroke and mortality adjusted to the WHO world population. We used only the most recent year reported to the WHO for which both population and mortality data were available. Results Fifty-one countries had data on stroke incidence, some with data over many time periods, and some with data in more than one region. Since our last review, there were new incidence studies from 12 countries, with four meeting pre-determined quality criteria. In these four studies, the incidence of stroke, adjusted to the WHO World standard population, ranged from 76 per 100,000 population per year in Australia (2009-10) up to 119 per 100,000 population per year in New Zealand (2011-12), with the latter being in those aged at least 15 years. Only in Martinique (2011-12) was the incidence of stroke greater in women than men. In countries either lacking or with old data on stroke incidence, eight had national clinical registries of hospital based data. Of the 128 countries reporting mortality data to the WHO, crude mortality was greatest in Kazhakstan (in 2003), Bulgaria, and Greece. Crude mortality and crude incidence of stroke were both positively correlated with the proportion of the population aged ≥ 65 years, but not with time. Data on case-fatality were available in 42 studies in 22 countries, with large variations between regions. Conclusions In this updated review, we describe the current data on stroke incidence, case-fatality and mortality in different countries, and highlight the growing trend for national clinical registries to provide estimates in lieu of community-based incidence studies.

Abstract
Background. Stroke is an important morbidity for low and middle income countries like Bangladesh. We established the first stroke registry in Bangladesh. Methods. Data was collected from stroke patients who were admitted in Department of Neurology of BIRDEM with first ever stroke, aged between 30 and 90 years. Patients with intracerebral hemorrhage, subarachnoid and subdural hemorrhage, and posttrauma features were excluded. Results. Data was gathered from 679 stroke patients. Mean age was 60.6 years. Almost 68% of patients were male. Small vessel strokes were the most common accounting for 45.4% of all the patients followed by large vessel getting affected in 32.5% of the cases. Only 16 (2.4%) died during treatment, and 436 (64.2%) patients had their mRS score of 3 to 5. Age greater than 70 years was associated with poor outcome on discharge [OR 1.79 (95% CI: 1.05 to 3.06)] adjusting for gender, duration of hospital stay, HDL, and pneumonia. Age, mRS, systolic blood pressure, urinary tract infection, pneumonia, and stroke severity explained the Barthel score. Conclusion. Mortality was low but most of patient had moderate to severe disability at discharge. Age, mRS, systolic blood pressure, urinary tract infection, pneumonia, and stroke severity influenced the Barthel score.

Abstract
PURPOSE To provide an up-to-date estimate on the changing prevalence of stroke survivors, and examines the geographic and socioeconomic variations in low and middle-income countries (LMICs). METHODS We searched MEDLINE, EMBASE, SCOPUS and Web of Science databases and systematically reviewed articles reporting stroke prevalence and risk factors from inception to July 2015. Pooled prevalence estimates and secular trends based on random-effects models were conducted across LMICs, World Bank regions and income groups. RESULTS Overall, 101 eligible community-based studies were included in the meta-analysis. The pooled crude prevalence of stroke survivors was highest in Latin America and Caribbean (21.2 per 1000, 95% CI 13.7 to 30.29) but lowest in sub-Saharan Africa (3.5 per 1000, 95% CI 1.9 to 5.7). Steepest increase in stroke prevalence occurred in low-income countries, increasing by 14.3% annually while the lowest increase occurred in lower-middle income countries (6% annually), and for every 10years increase in participants' mean age, the prevalence of stroke survivors increases by 62% (95% CI 6% to 147%). CONCLUSION The prevalence estimates of stroke survivors are significantly different across LMICs in both magnitude and secular trend. Improved stroke surveillance and care, as well as better management of the underlying risk factors, primarily undetected or uncontrolled high blood pressure (HBP) are needed.

Abstract
Background Two thirds of the global mortality of stroke is borne by low and middle income countries (LMICs). Pakistan is the world’s sixth most populous country with a stroke-vulnerable population and is without a single dedicated chronic care center. In order to provide evidence for a viable solution responsive to this health care gap, and leveraging the existing >70 % mobile phone density, we thought it rational to test the effectiveness of a mobile phone-based video intervention of short 5-minute movies to educate and support stroke survivors and their primary caregivers. Methods Movies4Stroke will be a randomized control, outcome assessor blinded, parallel group, single center superiority trial. Participants with an acute stroke, medically stable, with mild to moderate disability and having a stable primary caregiver will be included. After obtaining informed consent the stroke survivor-caregiver dyad will be randomized. Intervention participants will have the movie program software installed in their phone, desktop, or Android device which will allow them to receive, view and repeat 5-minute videos on stroke-related topics at admission, discharge and first and third months after enrollment. The control arm will receive standard of care at an internationally accredited center with defined protocols. The primary outcome measure is medication adherence as ascertained by a locally validated Morisky Medication Adherence Scale and control of major risk factors such as blood pressure, blood sugar and blood cholesterol at 12 months post discharge. Secondary outcome measures are post-stroke complications and mortality, caregiver knowledge and change in functional outcomes after acute stroke at 1, 3, 6, 9 and 12 months. Movies4Stroke is designed to enroll 300 participant dyads after inflating 10 % to incorporate attrition and non-compliance and has been powered at 95 % to detect a 15 % difference between intervention and usual care arm. Analysis will be done by the intention-to-treat principle. Discussion Movies4Stroke is a randomized trial testing an application aimed at supporting caregivers and stroke survivors in a LMIC with no rehabilitation or chronic support systems.

Abstract
With 16.9 million people who suffered a first-ever stroke in 2010 worldwide, stroke is a very common vascular disease. Epidemiologic studies have played an essential role in assessing this burden and in detecting the risk factors for stroke. Primary prevention of these risk factors, primarily hypertension, smoking, diabetes, and atrial fibrillation, has reduced the incidence in high-income countries. However, stroke remains a major cause of death and disability, and therefore research should be continued. Subarachnoid hemorrhages are less prevalent than strokes but have an even higher risk of death. Similar to stroke, epidemiologic studies identified smoking and hypertension as its most important risk factors, together with excessive alcohol intake. Although rare, arterial dissections, CADASIL, arteriovenous malformations, venous sinus thrombosis, moyamoya disease, and vasculitis can lead to serious symptoms. The burden and risk factors of those rare diseases are more challenging to assess. Whenever possible, they should be recognized in a timely manner for their increased risk of stroke, but most often they are diagnosed only at the time of stroke. Some cerebrovascular abnormalities do not result in immediate symptoms. This subclinical cerebrovascular disease includes silent infarcts, white-matter lesions, and microbleeds, and is incidentally found by neuroimaging. These lesions are not innocent, as several epidemiologic studies have associated subclinical cerebrovascular disease with an increased risk of stroke, cognitive decline, dementia, and death.

Maredza M, Bertram MY, Tollman SM. Disease burden of stroke in rural South Africa: an estimate of incidence, mortality and disability adjusted life years. BMC Neurol 2015; 15:54. [PMID: 25880843 PMCID: PMC4396076 DOI: 10.1186/s12883-015-0311-7] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2014] [Accepted: 03/25/2015] [Indexed: 01/05/2023] Open
Abstract
Background In the context of an epidemiologic transition in South Africa, in which cardiovascular disease is increasing, little is known about the stroke burden, particularly morbidity in rural populations. Risk factors for stroke are high, with hypertension prevalence of more than 50%. Accurate, up-to-date information on disease burden is essential in planning health services for stroke management. This study estimates the burden of stroke in rural South Africa using the epidemiological parameters of incidence, mortality and disability adjusted life year (DALY) metric, a time-based measure that incorporates both mortality and morbidity. Methods Data from the Agincourt health and socio-demographic surveillance system was utilised to calculate stroke mortality for the period 2007–2011. Dismod, an incidence-prevalence-mortality model, was used to estimate incidence and duration of disability in Agincourt sub-district and ‘mostly rural’ municipalities of South Africa. Using these values, burden of disease in years of life lost (YLL), years lived with disability (YLD) and DALYs was calculated for Agincourt sub-district. Results Over 5 years, there were an estimated 842 incident cases of stroke in Agincourt sub-district, a crude stroke incidence rate of 244 per 100,000 person years. We estimate that 1,070 DALYs are lost due to stroke yearly. Of this, YLDs contributed 8.7% (3.5 – 10.5%) in sensitivity analysis). Crude stroke mortality was 114 per 100,000 person-years in 2007–11 in Agincourt sub-district. Burden of stroke in entire rural South Africa, a population of some 13,000,000 people, was high, with an estimated 33, 500 strokes occurring in 2011. Conclusions This study provides the first estimates of stroke burden in terms of incidence, and disability in rural South Africa. High YLL and DALYs lost amongst the rural populations demand urgent measures for preventing and mitigating impacts of stroke. Longitudinal surveillance sites provide a platform through which a changing stroke burden can be monitored in rural South Africa.

Abstract
Noncommunicable disease (NCD), comprising cardiovascular disease, stroke, diabetes, and chronic obstructive pulmonary disease, are increasing in incidence rapidly in low- and middle-income countries (LMICs). Some patients have access to the same treatments available in high-income countries, but most do not, and different strategies are needed. Most research on noncommunicable diseases has been conducted in high-income countries, but the need for research in LMICs has been recognized. LMICs can learn from high-income countries, but they need to devise their own systems that emphasize primary care, the use of community health workers, and sometimes the use of mobile technology. The World Health Organization has identified "best buys" it advocates as interventions in LMICs. Non-laboratory-based risk scores can be used to identify those at high risk. Targeting interventions to those at high risk for developing diabetes has been shown to work in LMICs. Indoor cooking with biomass fuels is an important cause of chronic obstructive pulmonary disease in LMICs, and improved cookstoves with chimneys may be effective in the prevention of chronic diseases.

Abstract
In many countries, stroke is a lower priority than other diseases despite its public health impact. One issue is a lack of readily accessible comparative data to help make the case for the development of national stroke strategies. To assist in this process, we need to have a common repository of the latest published information on the impact of stroke worldwide. We aim to provide a repository of the most current incidence and mortality data on stroke available by country and illustrate the gaps in these data. We plan to update this repository annually and expand the scope to address other aspects of the burden of stroke. Data were compiled using two approaches: (1) an extensive literature review with a major focus on published systematic reviews on stroke incidence (between 1980 and May 14, 2013); and (2) direct acquisition and collation of data from the World Health Organization to present the most current estimates of stroke mortality for each country recognized by the World Health Organization. For mortality, ICD8, ICD9, and ICD10 mortality codes were extracted. Using population denominators crude stroke mortality was calculated, as well as adjusting for the World Health Organization world population. We used only the most recent year reported to the World Health Organization. Incidence rates for stroke were available for 52 countries, with some countries having incidence studies undertaken in more than one region. When adjusted to the World Health Organization world standard population, incidence rates for stroke ranged from 41 per 100 000 population per year in Nigeria (1971-74) to 316/ 100 000/year in urban Dar-es-Salaam (Tanzania). Some regions had three to fivefold greater incidence than other countries. Of the 123 countries reporting mortality data, crude mortality was greatest in Kazhakstan (in 2003). In many regions data were very old or nonexistent. Such country-level data are important for citizens, clinicians, and policy makers so that local and global strategies to reduce the overall burden of stroke can be implemented. Through this first annual review of country-specific stroke epidemiology, we hope to promote discussion and provide insights into the worldwide burden of stroke.

Abstract
OBJECTIVE To quantify the availability of informal caregivers in surviving stroke patients residing at home in Belgium. METHODS National estimates on the availability of informal caregivers were made using data from a nationwide observational registration of family physicians working in sentinel practices and a nationwide administrative database for reimbursement of hospitals in Belgium. RESULTS A total of 189 Belgian family physicians (FPs) from 141 practices participated in the study and recorded 326 patients (144 men and 182 women) with stroke. These FPs reach 1.5% of the Belgian population. After 1 month, 71% of the male and 75% of the female stroke survivors received support from family caregivers (p = 0.547). After 6 months, the percentage of male patients who received support from family caregivers decreased to 60% compared with 75% in female (p = 0.038). Of all patients with stroke admitted to Belgian hospitals during the reference year 2009 (n = 16.437), 8.997 returned home. Based on the findings from the sentinel practices, it is estimated that a mean of 73% (n = 6.568) and 67.5% (n = 6.073) of surviving patients with stroke can rely on informal caregivers in their home setting after one and 6 months, respectively. CONCLUSIONS A vast majority of surviving stroke patients in Belgium can rely on informal caregivers in their home setting, but their availability rapidly decreases 6 months after the event. These findings underline the importance of proactive health policy making in stroke care taking into account the potentially decreasing number of available informal caregivers in the decades to come.

Abstract
Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke. However, whether both factors exert a synergistic effect in the onset of stroke remains unclear. The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple intervertebral disk protrusion using a paired multivariate logistic regression method. Adjusting for known confounding variables including the patients' age, gender, smoking status, alcohol consumption status, patient and family medical history, and clinical biochemical indices, elevated homocysteine level was related to the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9 % increase in the risk for stroke compared to patients with normal homocysteine levels and blood lipids (odds ratio 1.409; 95% confidence interval 1.127-1.761). These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic effects in the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids are predisposed to stroke.

Abstract
BACKGROUND The burden of ischaemic and haemorrhagic stroke varies between regions and over time. With differences in prognosis, prevalence of risk factors, and treatment strategies, knowledge of stroke pathological type is important for targeted region-specific health-care planning for stroke and could inform priorities for type-specific prevention strategies. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010) to estimate the global and regional burden of first-ever ischaemic and haemorrhagic stroke during 1990-2010. METHODS We searched Medline, Embase, LILACS, Scopus, PubMed, Science Direct, Global Health Database, the WHO library, and regional databases from 1990 to 2012 to identify relevant studies published between 1990 and 2010. We applied the GBD 2010 analytical technique (DisMod-MR) to calculate regional and country-specific estimates for ischaemic and haemorrhagic stroke incidence, mortality, mortality-to-incidence ratio, and disability-adjusted life-years (DALYs) lost, by age group (aged <75 years, ≥ 75 years, and in total) and country income level (high-income and low-income and middle-income) for 1990, 2005, and 2010. FINDINGS We included 119 studies (58 from high-income countries and 61 from low-income and middle-income countries). Worldwide, the burden of ischaemic and haemorrhagic stroke increased significantly between 1990 and 2010 in terms of the absolute number of people with incident ischaemic and haemorrhagic stroke (37% and 47% increase, respectively), number of deaths (21% and 20% increase), and DALYs lost (18% and 14% increase). In the past two decades in high-income countries, incidence of ischaemic stroke reduced significantly by 13% (95% CI 6-18), mortality by 37% (19-39), DALYs lost by 34% (16-36), and mortality-to-incidence ratios by 21% (10-27). For haemorrhagic stroke, incidence reduced significantly by 19% (1-15), mortality by 38% (32-43), DALYs lost by 39% (32-44), and mortality-to-incidence ratios by 27% (19-35). By contrast, in low-income and middle-income countries, we noted a significant increase of 22% (5-30) in incidence of haemorrhagic stroke and a 6% (-7 to 18) non-significant increase in the incidence of ischaemic stroke. Mortality rates for ischaemic stroke fell by 14% (9-19), DALYs lost by 17% (-11 to 21%), and mortality-to-incidence ratios by 16% (-12 to 22). For haemorrhagic stroke in low-income and middle-income countries, mortality rates reduced by 23% (-18 to 25%), DALYs lost by 25% (-21 to 28), and mortality-to-incidence ratios by 36% (-34 to 28). INTERPRETATION Although age-standardised mortality rates for ischaemic and haemorrhagic stroke have decreased in the past two decades, the absolute number of people who have these stroke types annually, and the number with related deaths and DALYs lost, is increasing, with most of the burden in low-income and middle-income countries. Further study is needed in these countries to identify which subgroups of the population are at greatest risk and who could be targeted for preventive efforts.

Abstract
The paper focuses on the important issue of cardio-cerebral interactions, cardiac comorbidities, and the need for complex therapeutic approaches. While stroke is traditionally regarded as a neurologic problem, cardiologists play an important role in its prevention, via modification of multiple risk factors. One of the key preventive measures is arterial hypertension treatment. New calcium channel blockers are a promising group of modern antihypertensive medications.
