Alternativas para el contenido de un curso en linea de precálculo

El presente artículo muestra algunos desarrollos iniciales del Massive Open Online Course (MOOC) que apoya al curso tradicional de precálculo. Los aspectos teórico metodológicos que se tomaron en cuenta para su elección descansan en los entorpecimientos y las confusiones que los profesores actores del proyecto han detectado en sus propios estudiantes. Un grupo multidisciplinario de académicos, han plasmado a través del MOOC una alternativa de ayuda para los alumnos, donde se plantean, reflexionan y resuelven problemas o ejercicios, los cuales se clasificaron en: introductorios, representativos, difíciles o confusos. Cuando se tenga un resultado parcial, se efectuará una experimentación con alguno de los temas, contrastando su eficacia con respecto a estudiantes que lo emplean y los que no lo usan. El producto final se comparará con grupos de dos instituciones educativas de Nivel Superior

Gender differences and management of stroke risk of nonvalvular atrial fibrillation in an upper middle-income country: Insights from the CARMEN-AF registry

Background: Atrial Fibrillation (AF) is associated with an increased risk of stroke and systemic embolism. Several studies have suggested that female AF patients could have a greater risk for stroke. There is scarce information about clinical characteristics and use of antithrombotic therapies in Latin American patients with nonvalvular AF. Objective: To describe the gender differences in clinical characteristics, thromboembolic risk, and antithrombotic therapy of patients with nonvalvular AF recruited in Mexico, an upper middle-income country, into the prospective national CARMEN-AF Registry. Methods: A total of 1423 consecutive patients, with at least one thromboembolic risk factor were enrolled in CARMEN-AF Registry during a three-year period (2014–2017). They were categorized according to Gender. Results: Overall, 48.6% were women, mean age 70 ± 12 years. Diabetes, smoking, alcoholism, non-ischemic cardiomyopathy, coronary artery disease, and obstructive sleep apnea were higher in men. Most women were found with paroxysmal AF (40.6%), and most men with permanent AF (44.0%). No gender differences were found in the use of vitamin K antagonists (VKA) (30.5% in women vs. 28.0% in men). No gender differences were found in the use of direct oral anticoagulants (DOAC) (33.8% women vs 35.4% men). Conclusions: CARMEN-AF Registry demonstrates that in Mexico, regardless of gender, a large proportion of patients remain undertreated. No gender differences were found in the use of VKA or DOAC.
