ABSTRACT
ABSTRACT: BACKGROUND: The aim of this study was to assess the effectiveness of FAST stroke educational program among all preparatory school students in the state of Qatar. METHODS: The pretest-posttest experimental research design was used to evaluate the effectiveness of the FAST educational program in Qatar. A 30-minute audiovisual presentation was given to improve knowledge of stroke. We included grade 7 to 9 students during the academic year 2018-2019. The FAST program consisted of a pretest, an educational intervention, and immediate and long-term posttests at 2 months. RESULTS: A sample of 1244 students completed presurvey and immediate postsurvey, with an average age of 13.5 (1.12) years (range, 11-18 years) and 655 (53%) females. Students had significantly ( P < .01) greater knowledge of stroke signs, symptoms, and risk factors at intermediate posttest (5.9 [2.6] and 6.2 [2.4]) and at 2 months posttest (5.6 [2.8] and 5.6 [2.7]) compared with pretest (4.8 [2.6] and 4.9 [2.6], respectively). Students also had a higher self-efficacy to seek assistance, which was sustained from pretest to long-term posttest. CONCLUSION: The FAST program improved stroke knowledge that was retained at 2 months.

INTRODUCTION: Recurrent ischemic strokes (IS) make up to one-third of all strokes. Nine out of 10 strokes are due to modifiable risk factors. Thus, it seems that standard management strategies of modifiable risk factors are yet to improve. Hence, we planned a randomized controlled trial assessing nurses or pharmacists-led aggressive control of comorbidities and their prognostic impact on IS and transient ischemic attacks (TIA). METHODS/DESIGN: Prospective study to optimize the health of patients with TIAs and stroke admitted to the Hamad General Hospital (PROMOTE HEALTH) is an assessor-blinded, open-label, randomized, two-arm, controlled trial. Eligible patients have IS or TIA, and an additional modifiable risk factor (Hypertension or dyslipidemia) attending the stroke ward or clinic at the Weill Cornell-affiliated Hamad General Hospital. Stroke specialists will offer the control group the currently practiced best risk factor management strategies. Whereas, in the intervention arm, with the assistance of a nurse and a pharmacist, we will make aggressive attempts to meet targets of defined risk factors. The primary outcomes are the mean difference in blood pressure (BP) and low-density lipoprotein. Whereas myocardial infarction, recurrent stroke events, and mortality serve as the study's secondary outcomes. We require 200 patients per study arm to achieve a power of 80% and an alpha level of <0.05. The Medical Research Center and the Institutional Review Board have approved the study, and it was prospectively registered in a trial registry. DISCUSSION: A significant proportion of strokes are due to modifiable preventable risk factors. Despite having the right preventive strategies aimed at mitigating these risk factors, a sizeable proportion of strokes are due to recurring events. This prompted the medical community to evaluate aggressive means of addressing these risk factors. The nurse or pharmacist-led management of comorbidities has been proven to be of value in the management of diabetes and hypertension. It will be of value to demonstrate the effectiveness of utilizing this additional task force in aggressively managing IS or TIA patients with an overarching goal of improving their prognosis. If our intervention proves to be efficacious, this would have a substantial impact on the current stroke practices and guidelines. Additionally, it will invite further research in the area.

BACKGROUND: Sex differences may determine presentation, utility of treatment, rehabilitation, and occurrences of major adverse cardiovascular events (MACEs) in acute stroke (AS). OBJECTIVE: The purpose of the study was to evaluate the short-term prognosis and long-term outcomes in MACEs in Qatari nationals admitted with AS. METHODS: All AS patients admitted between January 2014 and February 2019 were included. We evaluated the preadmission modified Rankin scale (mRS) score, etiology and severity of symptoms, complications, and functional recovery at discharge and 90 days. MACEs were recorded for 5 years. RESULTS: There were 891 admissions for AS (mean age 64.0 ± 14.2 years) (male, n = 519 [mean age ± SD 62.9 ± 14.1 years]; female, n = 372 [mean age ± SD 65.6 ± 14.2 years] p = 0.005). There were no differences in the preadmission mRS and severity of symptoms as measured on National Institute of Stroke Scale. At discharge, the outcome was better (mRS 0-2) in men (57.8 vs. 46.0%), p = 0.0001. This difference persisted at the 90-day follow-up (mRS 0-2, male 69.4% vs. female 53.2%, p = 0.0001). At the 90-day follow-up, more women died (total deaths 70; women 38 [10.2%] versus men 32 [6.2%], p = 0.03). MACEs occurred in 25.6% (133/519) males and 30.9% (115/372) females over the 5-year follow-up period (odds ratio 0.77, 95% confidence interval 0.57-1.0, p = 0.83). CONCLUSIONS: Female patients have a poor short-term outcome following an AS when corrected for age and comorbidities. While our study cannot explain the reasons for the discrepancies, higher poststroke depression and social isolation in women may be important contributory factors, and requires further studies are required to confirm these findings.

Malignant middle cerebral artery [MMCA] infarction has a different topographic distribution that might confound the relationship between lesion volume and outcome. Retrospective study to determine the multivariable relationship between computerized tomographic [CT] infarct location, volume and outcomes in decompressive hemicraniectomy [DHC] for MMCA infarction. The MCA infarctions were classified into four subgroups by CT, subtotal, complete MCA [co-MCA], Subtotal MCA with additional infarction [Subtotal MCAAI] and co-MCA with additional infarction [Co-MCAAI]. Maximum infarct volume [MIV] was measured on the pre-operative CT. Functional outcome was measured by the modified Rankin Scale [mRS] dichotomized as favourable 0-3 and unfavourable ≥4, at three months. In 137 patients, from least favourable to favourable outcome were co-MCAAI, subtotal MCAAI, co-MCA and subtotal MCA infarction. Co-MCAAI had the worst outcome, 56/57 patients with additional infarction had mRS ≥ 4. Multiple comparisons Scheffe test showed no significant difference in MIV of subtotal infarction, co-MCA, Subtotal MCAAI but the outcome was significantly different. Multivariate analysis confirmed MCAAI [7.027 (2.56-19.28), p = 0.000] as the most significant predictor of poor outcomes whereas MIV was not significant [OR, 0.99 (0.99-01.00), p = 0.594]. Other significant independent predictors were age ≥ 55 years 12.14 (2.60-56.02), p = 0.001 and uncal herniation 4.98(1.53-16.19), p = 0.007]. Our data shows the contribution of CT infarction location in determining the functional outcome after DHC. Subgroups of patients undergoing DHC had different outcomes despite comparable infarction volumes.

In patients with malignant middle cerebral artery (MMCA) stroke, a vital clinically relevant question is determination of the speed with which infarction evolves to select the time for decompressive hemicraniectomy [DHC]. A retrospective, multicenter cross-sectional study of patients referred for DHC, based on the criteria of randomized controlled trials, was undertaken to identify factors for selecting the timing of DHC in MMCA stroke, stratified by time [< 48, 48-72, > 72 h]. Infarction volume and infarct growth rate [IGR] were measured on all CT scans. One hundred eighty-two patients [135 underwent DHC and 47 survived without DHC] were included in the analysis. After multivariate adjustment, factors showing the strongest independent association with DHC were patients < 55 years of age, septum pellucidum deviation, temporal lobe involvement, MCA with additional infarcts, and IGR on second CT. Of the five factors identified, different combinations of determining factors were observed in each subgroup. Both first and second IGRs were highest in the < 48, 48-< 72, and > 72 h [p < 0.001]. Patients who survived without surgery had the slowest IGRs. There was no association between time to DHC and infarct volume, although infarct volume was lower in patients who survived without DHC compared to the DHC subgroups. We identify the major risk factors associated with DHC in time-stratified subgroups of patients with MMCA. Evaluation of IGRs between the first and second scan and when possible second and third scan can help in selecting the timing of hemicraniectomy.
