The Effectiveness of Cognitive Flexibility Training Program on Cognitive Functions and Activities of Daily Living in Patients with Ischemic Stroke

Objective: To evaluate the effectiveness of a cognitive flexibility training program on cognitive functions and activities of daily living (ADLs) in patients with ischemic stroke. Methods: A single blind randomized controlled trial study was conducted in a stroke unit of a tertiary hospital in a Bangkok setting. The sample size was 80 participants of both genders, aged 18 – 80 years. The sample size was stratified by age. Randomization was generated by a computer program dividing 40 participants into the experiment and 40 into the control group. Eleven participants dropped out during data collection. Therefore, 34 participants in the experimental group received cognitive flexibility training four days a week for 30-40 minutes per day over a period of 4 weeks in addition to usual care. There were 35 participants in the control group who received diary recording and usual care. The study used various instruments for data collection, including a Thai version of the Montreal Cognitive Assessment and Barthel’s Index of Activities of Daily Living. Data were analyzed by multivariate analysis of covariance (MANCOVA). Results: The experiment group had higher cognitive functions and abilities in performing activities of daily living than the control group with statistical significance (p < .05). Conclusion: The study suggested that the program can be used to increase both cognitive functions and activities of daily living. Nurses and healthcare staff should apply this program in patients with acute ischemic stroke for nervous system recovery

COVID-19 pandemic and burden of non-communicable diseases: An ecological study on data of 185 countries

Background: The interaction between coronavirus disease 2019 (COVID-19) and non-communicable diseases may increase the global burden of disease. We assessed the association of COVID-19 with ageing and non-communicable diseases. Methods: We extracted data regarding non-communicable disease, particularly cardiovascular disease, deaths, disability-adjusted life years (DALYs), and healthy life expectancy (HALE) from the Global Burden of Disease Study (GBD) 2017. We obtained data of confirmed COVID-19 cases, deaths, and tests from the Our World in Data database as of May 28, 2020. Potential confounders of pandemic outcomes analyzed include institutional lockdown delay, hemispheric geographical location, and number of tourists. We compared all countries according to GBD classification and World Bank income level. We assessed the correlation between independent variables associated with COVID-19 caseload and mortality using Spearman\u27s rank correlation and adjusted mixed model analysis. Findings: High-income had the highest, and the Southeast Asia, East Asia, and Oceania region had the least cases per million population (3050.60 vs. 63.86). Sub-saharan region has reported the lowest number of COVID-19 mortality (1.9). Median delay to lockdown initiation varied from one day following the first case in Latin America and Caribbean region, to 34 days in Southeast Asia, East Asia, and Oceania. Globally, non-communicable disease DALYs were correlated with COVID-19 cases (r = 0.32, p\u3c0.001) and deaths (r = 0.37, p\u3c0.001). HALE correlated with COVID-19 cases (r = 0.63, p\u3c0.001) and deaths (r = 0.61, p\u3c0.001). HALE was independently associated with COVID-19 case rate and the number of tourists was associated with COVID-19 mortality in the adjusted model. Interpretation: Preventive measures against COVID-19 should protect the public from the dual burden of communicable and non-communicable diseases, particularly in the elderly. In addition to active COVID-19 surveillance, policymakers should utilize this evidence as a guide for prevention and coordination of health services. This model is timely, as many countries have begun to reduce social isolation

Post‐Market Registry of Stroke Patients Treated With Medtronic Neurothrombectomy Devices in Southeast Asia: PROSPR‐SEA

Background Southeast Asia accounts for approximately 10% of stroke‐related mortalities worldwide, yet there are limited data regarding mechanical thrombectomy (MT) outcomes in this region. PROSPR‐SEA (Post‐Market Registry of Stroke Patients Treated With Medtronic Neurothrombectomy Devices to Collect Real‐World Data in Southeast Asia) assessed post‐market clinical outcomes of MT using the Solitaire Revascularization Device in southeast Asia. Methods PROSPR‐SEA is a prospective, multicenter, nonrandomized, observational registry of patients who underwent MT using Solitaire as first line treatment at 1 of 10 centers in Vietnam, Thailand, and Singapore between January 2018 and July 2019. The primary end point was functional independence (modified Rankin scale 0–2) at 90 days. Safety end points included symptomatic intracerebral hemorrhage, emboli in new territory at 24 hours, and all‐cause mortality at 90 days. Secondary end points were successful revascularization (modified thrombolysis in cerebral infarction ≥2b), workflow metrics, National Institutes of Health Stroke Scale score at discharge, and patient disposition at 90 days. Results A total of 183 patients (64.9±13.7, 49.7% [91/183] female) were included in the study and underwent MT; 79.2% (145/183) had occlusions in the middle cerebral artery. Median baseline National Institutes of Health Stroke Scale was 15.0 (range 1–31) and median baseline Alberta Stroke Program Early CT Score was 8.0 (range 0–10). Functional independence at 90 days was achieved in 62.2% (112/180). Mean puncture‐to‐revascularization time was 53.3±53.9 minutes, and mean onset‐to‐revascularization time was 330.0±110.4 minutes. Revascularization was successful in 94.0% (172/183) of patients. Median National Institutes of Health Stroke Scale improved at discharge (−8.0, range −22, 25) and 90 days (−13.0, range −22, 0). Within 24 hours, symptomatic intracerebral hemorrhage occurred in 7.7% (14/183) and emboli in new territory in 3.3% (6/183). At 90 days, the all‐cause mortality rate was 7.7% (14/183). Most patients were discharged to home by 90 days (84.1%, 154/183). Conclusion PROSPR‐SEA demonstrated high rates of positive functional outcomes and procedural success with a low mortality rate and indicates that the technical and clinical outcomes of landmark MT trials using Solitaire as the first‐line device are reproducible in real‐world southeast Asian settings

Variations in the prevalence of atrial fibrillation, and in the strength of its association with ischemic stroke, in countries with different income levels: INTERSTROKE case–control study

Background: The contribution of atrial fibrillation (AF) to the etiology and burden of stroke may vary by country income level. Aims: We examined differences in the prevalence of AF and described variations in the magnitude of the association between AF and ischemic stroke by country income level. Methods: In the INTERSTROKE case–control study, participants with acute first ischemic stroke were recruited across 32 countries. We included 10,363 ischemic stroke cases and 10,333 community or hospital controls who were matched for age, sex, and center. Participants were grouped into high-income (HIC), upper-middle-income (subdivided into two groups—UMIC-1 and UMIC-2), and lower-middle-income (LMIC) countries, based on gross national income. We evaluated the risk factors for AF overall and by country income level, and evaluated the association of AF with ischemic stroke. Results: AF was documented in 11.9% (n = 1235) of cases and 3.2% (n = 328) of controls. Compared to HIC, the prevalence of AF was significantly lower in UMIC-2 (aOR 0.35, 95% CI 0.29–0.41) and LMIC (aOR 0.50, 95% CI 0.41–0.60) on multivariable analysis. Hypertension, female sex, valvular heart disease, and alcohol intake were stronger risk factors for AF in lower-income countries, and obesity a stronger risk factor in higher-income countries. The magnitude of association between AF and ischemic stroke was significantly higher in lower-income countries compared to higher-income countries. The population attributable fraction for AF and stroke varied by region and was 15.7% (95% CI 13.7–17.8) in HIC, 14.6% (95% CI 12.3–17.1) in UMIC-1, 5.7% (95% CI 4.9–6.7) in UMIC-2, and 6.3% (95% CI 5.3–7.3) in LMIC. Conclusion: Risk factors for AF vary by country income level. AF contributes to stroke burden to a greater extent in higher-income countries than in lower-income countries, due to a higher prevalence and despite a lower magnitude of odds ratio

Stroke Care Trends During COVID-19 Pandemic in Zanjan Province, Iran. From the CASCADE Initiative: Statistical Analysis Plan and Preliminary Results

Background: The emergence of the COVID-19 pandemic has significantly impacted global healthcare systems and this may affect stroke care and outcomes. This study examines the changes in stroke epidemiology and care during the COVID-19 pandemic in Zanjan Province, Iran. Methods: This study is part of the CASCADE international initiative. From February 18, 2019, to July 18, 2020, we followed ischemic and hemorrhagic stroke hospitalization rates and outcomes in Valiasr Hospital, Zanjan, Iran. We used a Bayesian hierarchical model and an interrupted time series analysis (ITS) to identify changes in stroke hospitalization rate, baseline stroke severity [measured by the National Institutes of Health Stroke Scale (NIHSS)], disability [measured by the modified Rankin Scale (mRS)], presentation time (last seen normal to hospital presentation), thrombolytic therapy rate, median door-to-needle time, length of hospital stay, and in-hospital mortality. We compared in-hospital mortality between study periods using Cox-regression model. Results: During the study period, 1,026 stroke patients were hospitalized. Stroke hospitalization rates per 100,000 population decreased from 68.09 before the pandemic to 44.50 during the pandemic, with a significant decline in both Bayesian [Beta: -1.034; Standard Error (SE): 0.22, 95% CrI: -1.48, -0.59] and ITS analysis (estimate: -1.03, SE = 0.24, p \u3c 0.0001). Furthermore, we observed lower admission rates for patients with mild (NIHSS \u3c 5) ischemic stroke (p \u3c 0.0001). Although, the presentation time and door-to-needle time did not change during the pandemic, a lower proportion of patients received thrombolysis (-10.1%; p = 0.004). We did not see significant changes in admission rate to the stroke unit and in-hospital mortality rate; however, disability at discharge increased (p \u3c 0.0001). Conclusion: In Zanjan, Iran, the COVID-19 pandemic has significantly impacted stroke outcomes and altered the delivery of stroke care. Observed lower admission rates for milder stroke may possibly be due to fear of exposure related to COVID-19. The decrease in patients treated with thrombolysis and the increased disability at discharge may indicate changes in the delivery of stroke care and increased pressure on existing stroke acute and subacute services. The results of this research will contribute to a similar analysis of the larger CASCADE dataset in order to confirm findings at a global scale and improve measures to ensure the best quality of care for stroke patients during the COVID-19 pandemic
