It is still unknown if attitudinal differences by diverse labeling of persons with epilepsy could be universally accepted with the actual literature evidence. The manner in which questions are constructed could also have an impact in final results. The purpose of this systematic review was to examine the published articles regarding changes in public´s attitude towards epilepsy by labeling a person as epileptic, person with epilepsy or with the acronym PWE.Methods: We undertook a systematic review of the literature using common databases with specific keywords and combinations searching for original articles, meta-analysis and systematic reviews. Sociodemographic variables, attitude results and questions style were analyzed in included articles.Results: Four original articles were found. Significant attitudinal changes were described in three studies with the label person with epilepsy. One study failed to demonstrate an attitudinal change by distinct labeling of a person with epilepsy. All questions were formulated in a personal way. Few neutral and mostly induced questions were found in the studies.Conclusion: By the use of the label "person with epilepsy" there is a trend towards positive changes in public's attitudes, although evidence is scarce to consider this tendency as universally applicable. More studies are needed considering widespread social and cultural backgrounds and patient opinion. Language power by wording type could be a key consideration for future studies.

Introduction: Stroke is the leading cause of disability in the world. Its incidence is increasing, even in young people. Therefore, the risk factors and various etiologies of stroke in young people should be studied to plan preventive actions. That is why in Colombia it is necessary to know these factors and etiologies analyzing the studies on the subject. Methods: Search and analysis of articles on causes and risk factors of ischemic stroke in Colombia published in Pubmed, Lilacs, Scielo, Google Scholar. After reviewing titles and abstracts, those that did not refer to young people between 18 and 49 years, reviews, did not refer to ischemic strokes, duplicates, were excluded. Finally, 20 articles were analyzed. Results and discussion: Most of the studies were report or case series, they added 60 people. There was no predominance of sex, except in the cases of antiphospholipid síndrome (APS) that were women, unlike most of the world series. The highest frequency was 56% for other determined causes such as APS and craniocervical vessel dissection, higher than other reports. There was a low frequency of large vessel disease, similar to other studies. Small vessel disease was higher than other reports in Latin America. Conclusions: Most of the information came from reports and case series that may not reflect the real frequency of causes and risk factors. Neurocysticercosis and psychoactive substances as causes of stroke proper of the review in Colombia deserve attention.

RESUMENLa investigación relacionada con el pronóstico se puede clasificar así: fundamental, que revela diferencias en desenlaces de salud; de factores pronósticos, que identifica y caracteriza variables; de desarrollo, validación y utilidad de modelos predictivos; y finalmente, de medicina estratificada, donde se establecen grupos de riesgo que comparten un factor asociado con el desenlace de interés. El desenlace en salud, o la condición de enfermedad que tendrá un individuo se pueden predecir considerando ciertas características asociadas, con anterioridad o simultáneamente, con dicho desenlace. Lo anterior puede hacerse mediante modelos predictivos pronósticos o diagnósticos. El desarrollo de un modelo predictivo exige cuidado en la selección, definición, medición y categorización de las variables predictoras; en la exploración de interacciones; en el número de variables que se van a incluir; en el cálculo del tamaño de la muestra; en el manejo de los datos perdidos; en las pruebas estadísticas que se van a usar y en la forma de presentación del modelo. El modelo así desarrollado se debe validar en un grupo diferente de pacientes para establecer su calibración, discriminación y utilidad. PALABRAS CLAVEDiagnóstico; Índice; Modelo; Predicción; Pronóstico; Regla SUMMARY Clinical and epidemiological round: Approach to clinical prediction modelsResearch related to prognosis can be classified as follows: fundamental, which shows differences in health outcomes; prognostic factors, which identifies and characterizes variables;

Background There is scarce information about ischemic stroke in young patients in Colombia. To get insights about this phenomenon, this study describes the etiologies and risk factors of ischemic stroke in young patients in a third level complexity referral hospital in Medellin, Colombia. Methods A retrospective observational cross-sectional study was carried out reviewing the medical records of patients between 18 to 49 years old admitted for the first time for ischemic stroke, from January 2009 to December 2019. The sociodemographic characteristics, risk factors, and etiological classification of ischemic stroke according to the Trial of Org 10,172 in Acute Stroke Treatment (TOAST) were described. Results Two hundred thirty-seven cases were found. The most frequent risk factors were arterial hypertension (31.7%), smoking (29.5%) and alcohol intake (23.2%). There was a greater number of traditional cardiovascular risk factors at older ages. The TOAST classification was large-artery atherosclerosis (6.8%), cardioembolism (17.7%), small-vessel disease (7.6%), other determined etiology (25.7%) and undetermined (42.2%). Within cardioembolism, the most common high-risk source was valve replacement, and the most common moderate-risk source was patent foramen ovale. Craniocervical arterial dissection (11.4%) and substance abuse (2.9%) were the two most frequent sources within other determined etiologies. The most common compromised vascular territory was the anterior (55.7%). Conclusions The high frequency of traditional risk factors in young patients highlights the need to optimize primary and secondary prevention plans. This study provides new insights about the relevance of illicit substance abuse in Colombia as a cause of stroke in young patients, unlike the previous one conducted in Bogotá. Infectious causes were other peculiarities found. It is necessary to investigate the reasons for the high proportion of undetermined causes.
