The data reinforce the need for further research on the acute and chronic effects of energy drinks to determine the actual risks and benefits. Consumers need to be more informed about the safety of these energy drinks, especially the young student population.
Antecedentes: las bebidas energizantes se promueven como curas milagrosas contra el cansancio, lo cual ha logrado que su consumo se incremente progresivamente. Objetivo: revisar el estado actual del conocimiento respecto a las bebidas energizantes y sus componentes, particularmente sus efectos benéficos y adversos. Materiales y métodos: se realizó una búsqueda bibliográfica abierta en las bases de datos Science Direct, Scielo, Medline y Pubmed utilizando diferentes combinaciones de los siguientes descriptores: energy drinks, marketing, caffeine, taurine, glucose, guarana, xantine, vitamins, pharmacology, heart rate, cognition, natural product, decision-making. Resultados: aunque no se conocen con claridad todos los componentes y sus concentraciones en las bebidas energizantes comercializadas, algunos de los componentes más comunes, tales como la cafeína y la taurina, tienen efectos adversos demostrados. Conclusión: no existen estudios concluyentes que demuestren los efectos benéficos de las bebidas energizantes, pero si existe suficiente evidencia de los efectos adversos de algunos de sus componentes más comunes. Son necesarios más estudios para determinar con certeza la seguridad de las bebidas energizantes, las cuales poseen un potencial tóxico considerable, que no es informado debidamente al consumidor.
Pseudoaneurysms are late and rare complications in the upper limbs due to penetrating vascular trauma. Although endovascular management is offered as the ideal approach, there are some anatomical conditions to consider surgical treatment. An 18-year-old patient was admitted into our hospital two months later after suffering a single gunshot on the left arm. The arteriography showed loss of most of the branchial artery (BA) course, which was replaced by an unusual 14 ∗ 10 cm pseudoaneurysm. The increasing deformity within the anterior compartment of the arm generated neuropathic and ischemic symptoms (NIS) that were resolved after the drainage and reconstruction of BA. An autologous, ipsilateral basilic vein (BV) graft was used for this purpose. After 26 months, the normal hemodynamic conditions of the treated limb allowed the patient to remain asymptomatic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
