Reestructuración de las Creencias Asociadas al Consumo de Drogas y la Conducción en Jóvenes

Abstract

El reto de reducir los accidentes de tráfico y reforzar la seguridad vial hace necesario concienciar, especialmente a la población juvenil, de los riesgos que lleva asociado el binomio drogas y conducción. El objetivo de este estudio es analizar los efectos de la aplicación de un programa preventivo que pretende modificar las actitudes de los jóvenes frente a drogas y conducción, además de investigar la relación entre la percepción del riesgo del consumo de drogas y la conducción según la variable sexo. Se ha realizado un estudio trasversal cuasi experimental en una muestra de 3,299 jóvenes de la provincia de Salamanca y de la capital, con un rango de edad comprendido entre los 15 y los 22 años, que cursaban bachillerato o ciclos formativos, a los cuales administramos un cuestionario ad hoc antes y después de concluir la intervención. El análisis de la varianza evidencia el cambio de las creencias y representaciones de las drogas y la percepción de riesgo en los jóvenes en relación al efecto de las diferentes sustancias en la conducción, resultando diferencias significativas entre ambos sexos respecto a la percepción de riesgo derivado del binomio drogas y conducción.

Strain Echocardiography and Myocardial Dysfunction in Critically Ill Children With Multisystem Inflammatory Syndrome Unrecognized by Conventional Echocardiography: A Retrospective Cohort Analysis

“…Global longitudinal strain has been studied extensively as a method to detect abnormal myocardial mechanics and has superior prognostic value to LVEF in predicting major adverse cardiac events and mortality (27)(28)(29)(30)(31)(32). While we found a higher prevalence of abnormal strain in patients with normal LVEF than other studies, the general observations of systolic dysfunction by SE in MIS-C patients with preserved LVEF are consistent with our results (10,11,23,24,33). The high prevalence of impaired strain in our cohort (86%) may arise from the clinical status of our patients being in the ICU with physiologic derangements consistent with more disease severity.…”

“…Published case series have reported abnormal LVEFs in 34-80% of MIS-C patients, with median LVEF values ranging from 46% to 60% (1,8,10,11,(23)(24)(25). This mild degree of dysfunction is similar to our study, where the median LVEF in our abnormal EF group was 48.1% and all patients was 61.4%.…”

“…In the absence of endomyocardial biopsies or cardiac MRI, elevation of serum biomarkers N-terminal brain natriuretic peptide (BNP), and troponin-I have been used to diagnose and quantify myocardial injury, as they correlate with the degree of myocardial inflammation (10). Echocardiographic findings during the acute phase of MIS-C have shown abnormalities in systolic function, atrioventricular valve regurgitation, and coronary artery abnormalities (11). Conventional echocardiographic assessment of systolic function uses left ventricular ejection fraction (LVEF); however, it can be limited by loading states (12).…”

Multisystem Inflammatory Syndrome in Children Associated with COVID-19 Infection: Clinical Presentation and Outcome

“…A systematic review by Ahmed et al 37 showed the use of corticosteroids and IVIG in 52.3 and 76.2% of cases, respectively. Coronary artery abnormalities have been reported in 8 to 24% of the cases in studies done by Jain et al 22 and Valverde et al 38 Due to limited resource setting, echocardiography could not be done at our center so we could not assess coronary artery abnormalities in our cases.…”

The Role of Mean Platelet Volume in Multisystem Inflammatory Syndrome in Children With Cardiac Manifestations

“…16,17 Additionally, a statistically significant correlation between the severity of elevation in cardiac and biochemical domains and the need for intensive care support has been reported with regard to such diseases. 18 Given this, routine blood testing is the initial diagnostic tool in clinical situations due to its low cost and ease of use. More importantly, because platelets play a crucial role in the inflammatory response, the mean platelet volume (MPV), as evaluated by a complete blood count (CBC), can be used as an inflammatory marker.…”
