YouTube as a source of recognizing acute stroke; progress in 2 years.

BACKGROUND: YouTube™ has a great role in providing information, which includes educational videos, to more than 2 billion users, making it the second most popular application in the world. BE-FAST is a modified version of the FAST mnemonic and is used to detect acute ischemic stroke by the patients or their relatives. The purpose of this study is to assess the overall usefulness of the information of YouTube in patients to realize an acute stroke attack. METHODS: YouTube was searched for the following five terms: "stroke", ''stroke diagnosis", "stroke signs", "brain attack" and "what is stroke" in November 2021 and May 2023, separately. Two independent neurology specialists scored each video by using Global Quality Scale (GQS). RESULTS: Among the total of 150 videos, the number that met inclusion criteria was 91 for the November 2021 search and 104 for the May 2023 search. For the 2021 search, in 30 videos (33%), the FAST mnemonic or its contents were noticed, whereas BE-FAST was mentioned in only four videos (4.4%). For the 2023 search, the FAST mnemonic or its contents were noticed in 36 videos (34.6%) and BE-FAST was mentioned in 11 videos (10.6%). Among the 2021 and 2023 searches, the mean GQS values were 3.09 and 2.96 points, 50 (54.8%) vs. 56 (53.8%) videos rated 3.5 points or higher (high quality), respectively. GQS scores of the videos mentioning balance, eyes, face, arms, speech, and time, the basic and advanced information about radiology and treatment, and mentioning FAST, BE-FAST, and TPA were significantly higher. CONCLUSION: We conclude that YouTube is not yet a very useful tool for patients to realize that they may have acute ischemic stroke, though over the years; information available on social media for healthcare information and education has improved.

Stroke Awareness and Knowledge in the At-Risk Population: A Community-Based Study.

BACKGROUND: The BE-FAST (balance, eyes, face, arms, speech, and time) mnemonic helps to identify stroke symptoms, which has been publicized through social media in Thailand for a while. Timely access to medical care enhances the likelihood of receiving efficacious treatment, thereby mitigating the adverse consequences of the stroke. Thus, stroke awareness in the general population, especially in the population at risk, is crucial. The purpose of the study was to evaluate stroke awareness and the level of knowledge about stroke in Thailand. METHODS: Adult participants aged at least 40 years, without a history of stroke, were included, with exclusions limited to those unwilling to participate. Data were gathered from the survey during two community visits and through an electronic survey via Google Forms (Google LLC, Mountain View, California, United States). A pre-tested questionnaire was divided into three parts: symptoms of acute stroke, vascular risk factors, and response. Demographics were compared between participants with good and poor knowledge of stroke awareness. RESULTS: A total of 281 participants were included, with a mean age of 58 years and 60% (n=169) of participants having at least one vascular risk factor. Of the responders, 133 (47%) had good knowledge of stroke awareness. Older age (age > 50 years, OR 0.326, 95%CI 0.173-0.615, p-value = 0.001), higher education (> 6 years, OR 0.266, 95%CI 0.139-0.508, p-value < 0.001)), and being female (OR 0.474, 95%CI 0.252-0.891, p-value = 0.020) were related to good stroke knowledge. Participants with good knowledge of stroke awareness also had good knowledge of vascular risk factors (84%; n=112), knew that they should come to the hospital immediately (74%; n=98), and also correctly identified the emergency calling number (90%; n=119). CONCLUSIONS: Only half of the participants had good knowledge of stroke awareness. There is a need for improvement in the distribution of knowledge about stroke in Thailand.

VISIBL-MS: A bilingual educational framework to increase awareness of early multiple sclerosis.

BACKGROUND: Despite advancements in treatments of multiple sclerosis (MS), there is a lack of awareness of early MS symptoms, especially in students and the public, contributing to delays in diagnosis and treatment. This review aims to identify gaps in tools to increase awareness and to provide a bilingual framework to facilitate recognition of early MS symptoms. METHODS: We performed a literature review to determine the use of English and Spanish mnemonics in MS education for medical students and patients. RESULTS: There is no educational tool to help remember the early signs of MS at present. Here we present a framework for early awareness encompassed in the bilingual mnemonics VISIBLY (English) and VISIBLE (Spanish). VISIBLY stands for (1) Vision changes: Painful vision loss, loss of color vision or double vision; (2) Belly or Back numbness and Balance issues; (3) Limb weakness or Numbness; (4), Young people. Spanish version is included in the manuscript. CONCLUSION: We posit that VISIBL-MS provides a framework for MS awareness that addresses the interconnection between language, culture, health literacy, and health outcomes and can be a useful educational tool to tackle the effects of health literacy on diverse communities.

BE-FAST: A Sensitive Screening Tool to Identify In-Hospital Acute Ischemic Stroke.

BACKGROUND: Development of acute ischemic stroke in hospitalized patients represents a significant proportion of all cerebral ischemia. Several prehospital stroke scales were developed to screen for acute ischemic stroke in the community. Despite the advent of inpatient stroke alert systems, there is a lack of validated screening tools for the inpatient population. This study aims to assess the validity of BE-FAST (Balance, Eyes, Face, Arm, Speech, Time) as a screening tool for acute ischemic stroke among inpatients. METHODS: We retrospectively analyzed all stroke alert activations at a single academic medical center between 2012 and 2016. We classified the triggering symptom as: focal neurologic deficit, aphasia, dysarthria, ataxia/vertigo/dizziness, alteration of consciousness, acute confusion, or headache. BE-FAST was applied retrospectively, and patients were classified as BE-FAST positive or negative. The final diagnosis was classified as acute ischemic stroke, transient ischemic attack , intracranial hemorrhage or noncerebrovascular diagnosis. RESULTS: Of 1965 stroke alerts, 489 were among inpatients. The mean age was 63 ± 16.1 years; 57% of patients were women (n = 1121). Acute ischemic stroke was diagnosed in 29% of all the activations (n = 567), transient ischemic attack in 12% (n = 232), intracranial hemorrhage in 8 % (n = 160) and noncerebrovascular in 51% (n = 1006). When comparing inpatient with community-onset stroke alerts, the sensitivity of BE-FAST for diagnosing acute ischemic stroke was 85% versus 94% (P = .005), with a specificity of 43% versus 23% (P < .001), respectively. However, when evaluating in-patients with an intact level of consciousness separately, BE-FAST sensitivity for diagnosing acute ischemic stroke was 92% compared to 94% in the community (P = .579). Among in-patients with acute ischemic stroke who were (1) candidates for reperfusion therapy and (2) diagnosed with acute large vessel occlusion, the sensitivity of BE-FAST was 83% and 94%, respectively. CONCLUSIONS: This is the first study to analyze the performance of BE-FAST among hospitalized patients evaluated through the inpatient stroke alert system. We found BE-FAST to be a very sensitive tool for screening for all in-hospital acute ischemic strokes, including inpatients that were candidates for acute reperfusion therapy.

Implementation and validation of an economic module in the Be-FAST model to predict costs generated by livestock disease epidemics: Application to classical swine fever epidemics in Spain.

Be-FAST is a computer program based on a time-spatial stochastic spread mathematical model for studying the transmission of infectious livestock diseases within and between farms. The present work describes a new module integrated into Be-FAST to model the economic consequences of the spreading of classical swine fever (CSF) and other infectious livestock diseases within and between farms. CSF is financially one of the most damaging diseases in the swine industry worldwide. Specifically in Spain, the economic costs in the two last CSF epidemics (1997 and 2001) reached jointly more than 108 million euros. The present analysis suggests that severe CSF epidemics are associated with significant economic costs, approximately 80% of which are related to animal culling. Direct costs associated with control measures are strongly associated with the number of infected farms, while indirect costs are more strongly associated with epidemic duration. The economic model has been validated with economic information around the last outbreaks in Spain. These results suggest that our economic module may be useful for analysing and predicting economic consequences of livestock disease epidemics.
