RESUMO
Resumen Introducción: La Facultad de Medicina de la Universidad Nacional Autónoma de México creó el Programa de Prevención de Embarazo en Adolescentes, dirigido a estudiantes. Objetivo: Determinar el perfil de la salud sexual-reproductiva de estudiantes de medicina mediante un cuestionario diagnóstico y de quienes participaron en una intervención educativa de sexualidad (tres módulos). Método: Participaron estudiantes del primer año de la carrera, ciclo 2017-2018. Se consideró que el estudiante fue capacitado cuando cursó al menos un módulo. Resultados: Contestaron el cuestionario 1157 estudiantes, 21.9 % participó en al menos un módulo, 43.1 % había iniciado vida sexual y 25 % recibió la intervención educativa. El 20 % no usó condón en su última relación y se observó alta prevalencia de relaciones sexuales bajo el influjo de alcohol. Conclusiones: Es importante promover competencias específicas en sexualidad entre quienes serán los futuros médicos.
Abstract Introduction: The National Autonomous University of Mexico Faculty of Medicine created the Adolescent Pregnancy Prevention Program, which is aimed at students. Objective: To determine the sexual-reproductive health profile of medical students through a diagnostic questionnaire and of those who participated in an educational intervention on sexuality (three modules). Method: First-year undergraduate students, schoolyear 2017-2018, participated. Students were considered to be trained when they took at least one module. Results: The questionnaire was answered by 1157 students, 21.9 % participated in at least one module, 43.1% had initiated sexual activity and 25 % received the educational intervention. Not having used a condom in their last intercourse was identified in 20 %, and a high prevalence of intercourse under the influence of alcohol was observed. Conclusions: It is important for specific sexuality competences to be promoted among those who will be doctors in the future.

The susceptible species Cedrela odorata and Swietenia macrophylla to attack by Hypsipyla grandella (Zeller) larvae were grafted onto the resistant species Khaya senegalensis and Toona ciliata. Six-month-old grafted plants were then compared to their reciprocal grafts and to both intact (non-grafted) and autografted plants for damage due to H. grandella larvae and for their effects on larval performance. Two experiments were conducted: one in which the apical bud of the main plant shoot was inoculated with H. grandella eggs, and the other in which the bud was inoculated with third instars. Damage in each experiment was assessed by the number of frass piles, number and length of tunnels, number of damaged leaves, and damage to the apical bud. Larval performance was evaluated in terms of time to reach pupation and pupal weight and length. In both experiments, plant damage differed significantly among treatments (P < 0.03). Resistant rootstocks conferred resistance to susceptible scions. In both experiments, grafting by itself, regardless of the rootstock and scion combination, also reduced damage caused by H. grandella larvae. Scions of autografted susceptible species had similar resistance to susceptible scions grafted on resistant rootstocks. Few larvae reached pupation, and their pupal weight and length were similar.
