    This study assessed the level of public awareness pertaining to risk factors, symptoms, treatment and source of information in relation to stroke and transient schaemic attack. Stroke risk profile of the respondents was correlated with their level of knowledge. Using a validated pre-tested questionnaire, 112 respondents were recruited during two separate community events. Respondents completed the questionnaire and underwent health screening. The data were analysed using SPSS version 20. Overall knowledge was poor. Only 35% of the respondents had satisfactory knowledge of the warning signs (p= 0.94) and 29% had satisfactory knowledge on the risk factors (p=0.46). When analysed according to risk groups, 26%, 30% and 41% of respondents had satisfactory awareness in the low, intermediate and high risk group, respectively. None of the respondents knew about the availability of treatment of acute stroke in the emergency department or the importance of rehabilitation as part of stroke management. Public awareness on stroke risk factors, symptoms and management is poor.

    There are various studies that have addressed the use of Cyclosporine among patients with acute myocardial infarction (AMI). However, to date there is hardly any concise and systematically structured evidence that debate on the efficacy and safety of Cyclosporine in AMI patients. The aim of this review is to systematically summarize the overall evidence from published trials, and to conduct a meta-analysis in order to determine the efficacy and safety of Cyclosporine vs. placebo or control among patients with AMI. All randomized control trial (RCT) published in English language from January 2000 to August 2017 were included for the systematic review and meta-analysis. A total of six RCTs met the inclusion and were hence included in the systematic review and meta-analysis. Based on the performed meta-analysis, no significant difference was found between Cyclosporine and placebo in terms of left ventricular ejection fraction (LVEF) improvement (mean difference 1.88; 95% CI -0.99 to 4.74; P = 0.2), mortality rate (OR 1.01; 95% Cl 0.60 to 1.67, P = 0.98) and recurrent MI occurrence (OR 0.65; 95% Cl 0.29 to 1.45, P = 0.29), with no evidence of heterogeneity, when given to patients with AMI. Cyclosporine also did not significantly lessen the rate of rehospitalisation in AMI patients when compared to placebo (OR 0.91; 95% Cl 0.58 to 1.42, P = 0.68), with moderate heterogeneity (I2 = 46%). There was also no significant improvement in heart failure events between Cyclosporine and placebo in AMI patients (OR 0.63; 95% Cl 0.31 to 1.29, P = 0.21; I2 = 80%). No serious adverse events were reported in Cyclosporine group across all studies suggesting that Cyclosporine is well tolerated when given to patients with AMI. The use of Cyclosporine in this group of patients, however, did not result in better clinical outcomes vs. placebo at improving LVEF, mortality rate, recurrent MI, rehospitalisation and heart failure event.

    This paper investigates the field-dependent rheological properties of magnetorheological (MR) fluid used to fill in MR dampers after long-term cyclic operation. For testing purposes, a meandering MR valve was customized to create a double-ended MR damper in which MR fluid flowed inside the valve due to the magnetic flux density. The test was conducted for 170,000 cycles using a fatigue dynamic testing machine which has 20 mm of stroke length and 0.4 Hz of frequency. Firstly, the damping force was investigated as the number of operating cycles increased. Secondly, the change in viscosity of the MR fluid was identified as in-use thickening (IUT). Finally, the morphological observation of MR particles was undertaken before and after the long-term operation. From these tests, it was demonstrated that the damping force increased as the number of operating cycles increases, both when the damper is turn on (on-state) and off (off-state). It is also observed that the particle size and shape changed due to the long operation, showing irregular particles.

    Stroke is the most important cause of death and foremost cause for dysfunction around the globe. As a result increase in the numberof elderly population the incidence of stroke has emerged as an important public health problem. Major developments have taken place in the field of medication for the prevention and treatment of stroke during the past decade. In spite of major interventions proposed by several organizations and the government, the present scenario of the stroke management facilities is still not promising. This article intends to investigate the health care facilities present for the elderly individuals with high risk of strokereoccurrence through proper analysis of the health system in Malaysia. The objectives are to find out evidence-based, reasonably priced and endurable measures to control the recurrences of stroke and to evaluate the outcomes of these interventions. It was noticed that in Malaysia though there many amenities for stroke patients are available but reorganizing and strengthening of few aspects such as human resource by multidisciplinary input is necessary for proper management of senior stroke patients. Moreover monitoring is essential to support patients after discharge from the hospital. The ethical variations among patient with stroke recurrence and the risk factor associated with stroke is not fully understood by healthcare workers. So, this study attempts to guide the stroke patient, their families and the health care workers to prevent stroke recurrence.

    BACKGROUND: Information regarding the knowledge on the action to be taken during stroke and good recognition of stroke symptoms is mandatory in helping to plan out educational strategies to deliver health education to the community.

    METHODS: This is a cross-sectional study of adults aged 18 and above attending a blood pressure screening program in community in conjunction with May Measurement Month 2017 in Malaysia. A structured self-administered questionnaire was given to the participants who gave verbal consent. Data analysis was done using SPSS v. 23 and multiple logistic regression was used to identify the determinants of knowledge on actions to be taken during stroke and recognition of stroke symptoms.

    RESULTS: Out of 4096 respondents, 82.9-92.1% of them able to recognise the common stroke symptoms. and 74.2% of the study respondents will go to hospital within 4.5 h of stroke onset. According to binomial logistic regression analyses, adults aged 45 years old and above (OR 1.39 95%CI 1.01-1.92), being Malay (OR 1.74, 95% CI 1.27-2.40), being non-smokers (OR = 2.491, 95% CI: 1.64-3.78), hypertensives (OR: 1.57, 95% CI: 1.02-2.42)and diabetics (OR: 2.54, 95% CI:1.38-4.69) are determinants of right actions to be taken during stroke. Meanwhile, respondents aged 45 years old and older (OR = 1.68, 95% CI: 1.39-2.03), being Malay (OR = 1.49, 95% CI: 1.24-1.79), hypertensive (OR = 1.32, 95% CI: 1.04-1.66) and those who had a previous history of stroke (OR = 2.25, 95% CI: 1.01-5.00) are determinants of good recognition of stroke symptoms.

    CONCLUSIONS: The overall knowledge of stroke in our study population was good. Older age, being Malay, non-smokers, hypertensives and diabetics are determinants of right actions to be taken during stroke. Meanwhile, older age, being Malay, hypertensive and those who had a previous history of stroke are determinants of good recognition of stroke symptoms.

    BACKGROUND: A comprehensive evaluation of interrater reliability is crucial when it comes to multiple coders assessing the stroke outcomes using telephone interview. The reliability between telephone raters is important, as it could affect the accuracy of the findings published.

    OBJECTIVE: This study aimed to establish the interrater reliability between multiple telephone interviewers when assessing long-term stroke outcomes.

    METHODS: Patients alive at discharge selected in a retrospective cohort stroke project were recruited in this study. Their contact numbers were obtained from the medical record unit. The patients and/or proxies were interviewed based on a standardized script in Malay or English. Stroke outcomes assessed were modified Rankin Scale (mRS) and Barthel Index (BI) at 1-year post discharge. Fully crossed design was applied and 3 assessors collected the data simultaneously. Data was analysed using the software R version 3.4.4.

    RESULTS: Out of 207 subjects recruited, 132 stroke survivors at the time of interview were analysed. We found a significant excellent interrater reliability between telephone interviewers assessing BI, with intraclass correlation coefficient at 0.996 (95% CI 0.995-0.997). Whereas substantial agreement between the telephone interviewers was revealed in assessing mRS, with Fleiss', Conger's and Light's Kappa statistics reporting 0.719 and the Nelson's model-based κm kappa statistic reporting 0.689 (95% CI 0.667-0.711).

    CONCLUSION: It is reliable to get multiple raters in assessing mRS and BI using the telephone system. It is worthwhile to make use of a telephone interview to update clinicians on their acute clinical management towards long-term stroke prognosis.

    Motor impairment is the most common and widely recognised clinical outcome after stroke. Current clinical practice in stroke rehabilitation focuses mainly on physical therapy, with no pharmacological intervention approved to facilitate functional recovery. Several studies have documented positive effects of growth hormone (GH) on cognitive function after stroke, but surprisingly, the effects on motor function remain unclear. In this study, photothrombotic occlusion targeting the motor and sensory cortex was induced in adult male mice. Two days post-stroke, mice were administered with recombinant human GH or saline, continuing for 28 days, followed by evaluation of motor function. Three days after initiation of the treatment, bromodeoxyuridine was administered for subsequent assessment of cell proliferation. Known neurorestorative processes within the peri-infarct area were evaluated by histological and biochemical analyses at 30 days post-stroke. This study demonstrated that GH treatment improves motor function after stroke by 50%-60%, as assessed using the cylinder and grid walk tests. Furthermore, the observed functional improvements occurred in parallel with a reduction in brain tissue loss, as well as increased cell proliferation, neurogenesis, increased synaptic plasticity and angiogenesis within the peri-infarct area. These findings provide new evidence about the potential therapeutic effects of GH in stroke recovery.

    BACKGROUND: Heart failure (HF) trials have stringent inclusion and exclusion criteria, but limited data exist regarding generalizability of trials. We compared patient characteristics and outcomes between patients with HF and reduced ejection fraction (HFrEF) in trials and observational registries.

    METHODS AND RESULTS: Individual patient data for 16 922 patients from five randomized clinical trials and 46 914 patients from two HF registries were included. The registry patients were categorized into trial-eligible and non-eligible groups using the most commonly used inclusion and exclusion criteria. A total of 26 104 (56%) registry patients fulfilled the eligibility criteria. Unadjusted all-cause mortality rates at 1 year were lowest in the trial population (7%), followed by trial-eligible patients (12%) and trial-non-eligible registry patients (26%). After adjustment for age and sex, all-cause mortality rates were similar between trial participants and trial-eligible registry patients [standardized mortality ratio (SMR) 0.97; 95% confidence interval (CI) 0.92-1.03] but cardiovascular mortality was higher in trial participants (SMR 1.19; 1.12-1.27). After full case-mix adjustment, the SMR for cardiovascular mortality remained higher in the trials at 1.28 (1.20-1.37) compared to RCT-eligible registry patients.

    CONCLUSION: In contemporary HF registries, over half of HFrEF patients would have been eligible for trial enrolment. Crude clinical event rates were lower in the trials, but, after adjustment for case-mix, trial participants had similar rates of survival as registries. Despite this, they had about 30% higher cardiovascular mortality rates. Age and sex were the main drivers of differences in clinical outcomes between HF trials and observational HF registries.

    INTRODUCTION: This study aimed to investigate the direct cost of outpatient care for patients with stroke, as well as the relationship between the aforementioned cost and the sociodemographic and stroke characteristics of the patients.

    METHODS: This was a cross-sectional study involving patients with first-ever stroke who were attending outpatient stroke rehabilitation, and their family members. Participants were interviewed using a structured questionnaire designed to obtain information regarding the cost of outpatient care. Stroke severity was measured using the National Institute of Health Stroke Scale.

    RESULTS: This study comprised 49 patients (28 men, 21 women) with a mean age of 60.2 (range 35-80) years. The mean total cost incurred was USD 547.10 (range USD 53.50-4,591.60), of which 36.6% was spent on attendant care, 25.5% on medical aids, 15.1% on travel expenses, 14.1% on medical fees and 8.5% on out-of-pocket expenses. Stroke severity, age > 70 years and haemorrhagic stroke were associated with increased cost. The mean cost of attending outpatient therapy per patient was USD 17.50 per session (range USD 6.60-30.60), with travelling expenses (41.8%) forming the bulk of the cost, followed by medical fees (38.1%) and out-of-pocket expenses (10.9%). Multiple regression analysis showed that stroke severity was the main determinant of post-stroke outpatient care cost (p < 0.001).

    CONCLUSION: Post-stroke outpatient care costs are significantly influenced by stroke severity. The cost of attendant care was the main cost incurred during the first three months after hospital discharge, while travelling expenses was the main cost incurred when attending outpatient stroke rehabilitation therapy.

    In this study, we assessed the impact of COVID-19 on the course of HFmrEF by determining the biomarkers furin and NT-proBNP, questionnaires (EQ-5D-5L), and cardiac ultrasound. A comprehensive examination of 72 patients with HFmrEF (main group) and 18 apparently healthy individuals (control group). The main group was divided into two subgroups depending on the history of coronavirus disease. All patients gave their consent to participate in the study. In the group of patients with a history of coronavirus infection compared to the patients without a COVID-19 history were established: significantly higher concentrations of NT-proBNP (1002.79±215.94 pg/ml and 405.37±99.06 pg/ml, respectively, p-value 0.01), uric acid (429.08±27.01 mmol/l vs. 354.44±28.75 mmol/l, p-value 0.04) and a lower furin to NT-proBNP ratio (0.87± 0.26 and 1.38 ± 1.16, p-value 0.045) in blood serum; using the EQ-5D-5L questionnaire, a significant deterioration of quality of life indicators (64.21±3.04 points vs. 72.81±1.82 points by VAS, p-value 0.02); higher indicators of LVMMi (157.39±6.14 g/m2 and 138.68±6.02 g/m2, p-value 0.03), LA dimensions (43.74±0.95 mm and 41.12±0.85 mm, p-value 0.04) and RA dimensions (40.76±1.23 mm and 37.75±0.85 mm, p-value 0.04). Coronavirus infection in patients with HFmrEF leads to disorders of intracardiac hemodynamics and persistent negative structural changes of the heart. The ratio of furin to NT-proBNP serum levels can be used to determine the impact of the HF syndrome itself on the patients' subjective assessment of their quality of life.

    BACKGROUND: Gastrostomy feeding is superior to long-term nasogastric (NG) feeding in patients with dysphagic stroke, but this practice remains uncommon in Asia. We sought to examine the nutritional adequacy of patients on long term NG feeding and identify barriers to gastrostomy feeding in these patients.

    METHODOLOGY: A prospective comparison of subjective global assessment (SGA), and anthropometry (mid-arm muscle circumference, MAMC; triceps skinfold thickness, TST) between elderly stroke patients on long-term NG feeding and matched controls was performed. Selected clinicians and carers of patients were interviewed to assess their knowledge and attitudes to gastrostomy feeding.

    RESULTS: 140 patients (70 NG, 70 oral) were recruited between September 2010 and February 2011. Nutritional status was poorer in the NG compared to the oral group (SGA grade C 38.6% NG vs 0% oral, p<0.001; TST males 10.7 + 3.7 mm NG vs 15.4 + 4.6 mm oral, p<0.001; MAMCmales 187.9 + 40.4 mm NG vs 228.7 + 31.8 mm oral, p<0.001). 45 (64.3%) patients on long-term NG feeding reported complications, mainly consisting of dislodgement (50.5%), aspiration of feed content (8.6%) and trauma from insertion (4.3%). Among 20 clinicians from relevant speciliaties who were interviewed, only 11 (55%) clinicians would routinely recommend a PEG. All neurologists (100%) would recommend a PEG, whilst the response was mixed among non-neurologists. Among carers, lack of information (47.1%) was the commonest reason stated for not choosing a PEG.

    CONCLUSION: Elderly patients with stroke on long term NG feeding have a poor nutritional status. Lack of recommendation by clinicians appears to be a major barrier to PEG feeding in these patients.

    Fractal dimensions (FDs) are frequently used for summarizing the complexity of retinal vascular. However, previous techniques on this topic were not zone specific. A new methodology to measure FD of a specific zone in retinal images has been developed and tested as a marker for stroke prediction. Higuchi's fractal dimension was measured in circumferential direction (FDC) with respect to optic disk (OD), in three concentric regions between OD boundary and 1.5 OD diameter from its margin. The significance of its association with future episode of stroke event was tested using the Blue Mountain Eye Study (BMES) database and compared against spectrum fractal dimension (SFD) and box-counting (BC) dimension. Kruskal-Wallis analysis revealed FDC as a better predictor of stroke (H = 5.80, P = 0.016, α = 0.05) compared with SFD (H = 0.51, P = 0.475, α = 0.05) and BC (H = 0.41, P = 0.520, α = 0.05) with overall lower median value for the cases compared to the control group. This work has shown that there is a significant association between zone specific FDC of eye fundus images with future episode of stroke while this difference is not significant when other FD methods are employed.

    The original concept of the ischaemic penumbra suggested imaging of regional cerebral blood flow and metabolism would be required to identify tissue that may benefit from intervention. Amide proton transfer magnetic resonance imaging, a chemical exchange saturation transfer technique, has been used to derive cerebral intracellular pH in preclinical stroke models and has been proposed as a metabolic marker of ischaemic penumbra. In this proof of principle clinical study, we explored the potential of this pH-weighted magnetic resonance imaging technique at tissue-level. Detailed voxel-wise analysis was performed on data from a prospective cohort of 12 patients with acute ischaemic stroke. Voxels within ischaemic core had a more severe intracellular acidosis than hypoperfused tissue recruited to the final infarct (P < 0.0001), which in turn was more acidotic than hypoperfused tissue that survived (P < 0.0001). In addition, when confined to the grey matter perfusion deficit, intracellular pH (P < 0.0001), but not cerebral blood flow (P = 0.31), differed between tissue that infarcted and tissue that survived. Within the presenting apparent diffusion coefficient lesion, intracellular pH differed between tissue with early apparent diffusion lesion pseudonormalization and tissue with true radiographic recovery. These findings support the need for further investigation of pH-weighted imaging in patients with acute ischaemic stroke.

    This study aims to identify the predictors in the different aspects of the health-related quality of life (HRQoL) and to measure the changes of functional status over time in a cohort of Nigerian stroke survivors. A prospective observational study was conducted in three hospitals of Kano state of Nigeria where stroke survivors receive rehabilitation. The linguistic-validated Hausa versions of the stroke impact scale 3.0, modified Rankin scale, Barthel index and Beck depression inventory scales were used. Paired samples t-test was used to calculate the amount of changes that occur over time and the forward stepwise linear regression model was used to identify the predictors. A total of 233 stroke survivors were surveyed at 6 months, and 93% (217/233) were followed at 1 year after stroke. Functional disabilities were significantly reduced during the recovery phase. Motor impairment, disability, and level of depression were independent predictors of HRQoL in the multivariate regression analysis. The involvement of family members as caregivers is the key factor for those survivors with improved functional status. Thus, to enhance the quality of poststroke life, it is proposed that a holistic stroke rehabilitation service and an active involvement of family members are established at every possible level.

    Cerebral ischemia or ischemic stroke is mainly attributed to vascular and circulation disorders. Among protein biomarkers, RNA profiles have also been identified as markers of ischemic stroke. MicroRNA-145 expression is ostensibly recognized as marker and modulator of vascular smooth muscle cell phenotype; however, expression levels in ischemic stroke had not been investigated. Employing real-time quantitative PCR, we examined the expression profile of circulatory microRNA-145 in healthy control subjects (N = 14) and ischemic stroke patients (N = 32). Circulatory microRNA-145 expression was significantly higher in ischemic stroke patients than in control subjects. This demonstrates that hemostatic mechanisms are affected by ischemic stroke. We conclude that circulating microRNA-145 has potential as a biomarker for ischemic stroke.

    The National Stroke Registry (NSR) was established in 2009 under National Neurology Registry (NNeuR) . The main objectives of NSR were to describe the demographic and disease pattern of stroke patients in Malaysia, to examine the risk factors and evaluate the specified treatment and outcomes. This prospective observational study was carried out from August 2009 until December 2010 using a standardized case report form which involved two participating hospital, namely Hospital Sultanah Nur Zahirah, Kuala Terengganu and Hospital Seberang Jaya, Pulau Pinang. There were 1018 patients registered. Ischemic stroke accounted for the majority of cases (73.3%). The most common risk factor was hypertension (75.5 %), followed by diabetes mellitus, previous stroke or Transient Ischemic Attack (TIA), hyperlipidemia and active smoker: 45.6%, 25.1%, 22.4%, and 19.4%, respectively. Overall, our stroke management, based on nine stroke key performance indicators (KPI) still needs to be improved. There was a total of 121 mortality cases with the main contributing factor was massive cerebral bleed (21.6%). In conclusion, the findings highlight the important of primary and secondary stroke management. Further and continuous observation with more site date provider (SDP) involvement is needed to get a more comprehensive data on stroke in Malaysia.

    Stroke causes a devastating insult to the brain resulting in severe neurological deficits because of a massive loss of different neurons and glia. In the United States, stroke is the third leading cause of death. Stroke remains a significant clinical unmet condition, with only 3% of the ischemic patient population benefiting from current treatment modalities, such as the use of thrombolytic agents, which are often limited by a narrow therapeutic time window. However, regeneration of the brain after ischemic damage is still active days and even weeks after stroke occurs, which might provide a second window for treatment. Neurorestorative processes like neurogenesis, angiogenesis and synaptic plasticity lead to functional improvement after stroke. Stem cells derived from various tissues have the potential to perform all of the aforementioned processes, thus facilitating functional recovery. Indeed, transplantation of stem cells or their derivatives in animal models of cerebral ischemia can improve function by replacing the lost neurons and glial cells and by mediating remyelination, and modulation of inflammation as confirmed by various studies worldwide. While initially stem cells seemed to work by a 'cell replacement' mechanism, recent research suggests that cell therapy works mostly by providing trophic support to the injured tissue and brain, fostering both neurogenesis and angiogenesis. Moreover, ongoing human trials have encouraged hopes for this new method of restorative therapy after stroke. This review describes up-to-date progress in cell-based therapy for the treatment of stroke. Further, as we discuss here, significant hurdles remain to be addressed before these findings can be responsibly translated to novel therapies. In particular, we need a better understanding of the mechanisms of action of stem cells after transplantation, the therapeutic time window for cell transplantation, the optimal route of cell delivery to the ischemic brain, the most suitable cell types and sources and learn how to control stem cell proliferation, survival, migration, and differentiation in the pathological environment. An integrated approach of cell-based therapy with early-phase clinical trials and continued preclinical work with focus on mechanisms of action is needed.

    Gastrointestinal (GI) bleeding is one of the most serious complications after an acute ischaemic stroke and may affect stroke outcome. We identified predictors and the eventual outcome of gastrointestinal bleeding during the in-patient period following the commencement of aspirin. This was a study of patients with acute ischaemic stroke admitted to Universiti Kebangsaan Malaysia Hospital from June 2000 to January 2001. A single observer, using predefined diagnostic criteria recorded information on demography, risk factors and GI bleeding that occurred during the inpatient period. One hundred and fifteen patients with acute ischaemic stroke were enrolled in the study. Gastrointestinal bleeding was observed in 6 (5.2%) patients. Using univariate analysis, the independent predictors of gastrointestinal bleeding were age (OR 1.25; 95% CI 1.07 to 1.50), and middle cerebral artery (MCA) territory infarcts (OR 9.47; 95% CI 1.62 to 55.5). Using multivariate analysis, the presence of gastrointestinal bleeding increased mortality (OR 24.97; 95% CI 1.97 to 316.91). Older age, and large MCA infarct predict the development gastrointestinal bleeding. Stroke mortality was independently predicted by gastrointestinal bleeding. Prophylactic treatment in elderly patients with large cerebral infarcts may be an area for further investigation.
