IX Congreso Nacional de estudiantes de Medicina

Escrito por

La IX edición del Congreso Nacional de estudiantes de Medicina, organizado por la Asociación de Estudiantes “Ramón y Cajal” de la Facultad de Medicina de Granada, ya está en marcha. Desde el martes 22 hasta el viernes 25 de marzo, tiene lugar este congreso (que también alcanza su tercera edición internacional) durante el cual se alternan mesas redondas, talleres, conferencias magistrales y comunicaciones de trabajos de investigación de los alumnos participantes.

El martes 22 se produjo la recogida de materiales del congreso, y el miércoles 23 la inauguración del congreso, cuya mesa de honor estuvo formada por la Vicerrectora de Estudiantes de la Universidad de Granada, Dª Inmaculada Marrero Rocha; el Decano de la Facultad de Medicina de Granada, Prof. Dr. Indalecio Sánchez-Montesinos García; el Presidente del Colegio de Médicos de Granada, Dr. Javier de Teresa Galván; el Prof. Dr. Miguel Alaminos Mingorance (en representación del Prof. Dr. Antonio Campos Muñoz, Presidente Honorífico del Congreso, que no pudo asistir a la inauguración); y Dª Laura Romacho López, Presidenta del Congreso y de la Asociación de Estudiantes “Ramón y Cajal”.

De izquierda a derecha: Prof. Dr. Carlos Ruiz Cosano, Vicedecano de la Facultad de Medicina de Granada; Dr. Javier De Teresa Galván, Presidente del Colegio de Médicos de Granada; Dª Inmaculada Marrero Rocha, Vicerrectora de Estudiantes de la Universidad de Granada; y el Prof. Dr. Indalecio Sánchez-Montesinos García, Decano de la Facultad Medicina de Granada; posando junto al stand del Colegio Oficial de Médicos en el Congreso.

Fue precisamente esta última la primera en tomar la palabra para agradecer a todos los presentes su participación en el congreso, señalando la necesidad de acciones como ésta para tener un mayor conocimiento de la Medicina, no solo desde el punto de vista meramente académico, sino también desde otros puntos de vista: organizacionales, sociales, y de conocimiento mutuo entre estudiantes de diversas facultades a nivel nacional e internacional.

A continuación, el Prof. Dr. Miguel Alaminos se dirigió a los estudiantes para, en primer lugar, disculpar la forzosa ausencia del Dr. Campos Muñoz; señalando que el apoyo de los profesores y todos los docentes a este congreso es total, puesto que es una actividad académica de alto valor, que además aporta un valor humano absolutamente necesario para la formación de un médico.

La tercera intervención estuvo a cargo del Dr. Javier de Teresa, quien remarcó la importancia de este congreso que, en cada edición, ha cobrado una mayor carga de contenidos y actividades; reseñando que “el médico no se hace sólo con un título de licenciado, sino también con la vocación de médico que nos acompaña desde que tomamos la decisión de servir a los demás; y que no termina nunca ni tiene paréntesis, puesto que somos médicos en todos los momentos de nuestra vida, en casa o en el trabajo”. Por ello, “compartir experiencias con los compañeros, aprender a exponer y presentar trabajos, a organizar un congreso o a participar en él, participar en los talleres o en las ponencias, es una parte esencial del profesional médico y de la persona”. Por último, incidió en la elección del mismo día 23 de marzo como “Día Nacional contra las agresiones en el ámbito sanitario”, una iniciativa promovida desde el Consejo General de Colegios de Médicos (CGCOM) y la Confederación Estatal de Sindicatos Médicos (CESM) para promover una actuación global frente a las agresiones al personal sanitario; señalando que ambas organizaciones habían emitido un manifiesto conjunto que sería leído al final del acto de inauguración del congreso.

El Decano de la Facultad de Medicina, Dr. Sánchez-Montesinos, se dirigió a los presentes para darles la bienvenida (especialmente a los foráneos, a quienes señaló que “Granada les recibe con los brazos abiertos”), esperando que este congreso sea de especial provecho en todas las facetas. Remarcó que “como en otros congresos, hay muchas formas de acudir a los mismos, pero yo espero que en el presente sea con voluntad de participar y escuchar atentamente, con vocación de recibir conocimientos que serán importantes para un médico del siglo XXI”. Afirmó que el valor del médico no solo implica el conocimiento técnico o teórico de la Medicina, sino el valor humano del médico como persona y profesional, al que actividades como el presente congreso aporta muchas valiosas enseñanzas y herramientas.

En la misma línea, la Vicerrectora de Estudiantes de la Universidad de Granada, Dª Inmaculada Marrero, señaló que la formación de los estudiantes tiene un componente integral que es esencial, y que el presente congreso fomenta y enriquece. Afirmó que para la Universidad de Granada es especialmente grato auspiciar y apoyar actividades como esta, puesto que “no es una actividad social o cultural más, sino una actividad docente con ponentes de primer nivel y actividades de una utilidad académica esencial”.

Al final del acto, se procedió a la lectura pública del manifiesto elaborado por el Observatorio de Agresiones y otros miembros del CGCOM junto con representantes de CESM, en el que se insta a un tratamiento multidimensional de este fenómeno.

Como ya se ha comentado, durante los días del congreso tendrán lugar toda una serie de actividades, entre las cuales podemos destacar:

El propio día 23 de marzo, el Prof. Dr. Juan Jiménez Alonso moderó una Sesión de Casos Clínicos (que también modera mensualmente en el Colegio de Médicos de Granada, dentro de la programación docente de la institución) para todos los estudiantes interesados en conocer el desarrollo de estas sesiones.

El jueves 24, el Vicepresidente del Colegio de Médicos de Granada, Prof. Dr. José Antonio Lorente Acosta, dirigió una mesa redonda titulada “Medicina Genómica”. Cabe recordar que el Dr. Lorente es igualmente Director del centro “GENyO” (Centro de Genómica e Investigación Oncológica de Andalucía), y es Profesor titular del Departamento de Medicina Legal de la Universidad de Granada.

El viernes día 25 tendrá lugar una ponencia del Colegio de Médicos de Granada, a cargo del Dr. Fernando de Teresa Galván, Director del AulaMIR del Colegio Oficial de Médicos de Granada; sobre las novedades en el examen MIR y las perspectivas de futuro del mismo.

Los coleccionables pueden provocar el trastorno obsesivo compulsivo en personas con propensión

Escrito por

La excesiva publicidad que las editoriales dan a todo tipo de coleccionables puede provocar que las personas con tendencia a sufrir un trastorno obsesivo compulsivo desarrollen antes esta patología. Y es que coleccionar objetos de manera exagerada es un síntoma de este grave problema psicológico (una de cuyas variantes es el conocido como «Síndrome de Diógenes») y de la adicción a las compras, dos enfermedades mentales que afectan, aproximadamente, al 12% de la población.

La profesora Francisca López Torrecillas, del departamento de Personalidad, Evaluación y Tratamiento Psicológico de la Universidad de Granada y experta en adicciones, advierte de que en los últimos años «se ha detectado un aumento muy importante» de casos en los que el coleccionismo exagerado ha desembocado en un trastorno obsesivo compulsivo o en una adicción a las compras.

La investigadora destaca que rasgos como una excesiva necesidad de control, el perfeccionismo o la meticulosidad y el orden «son muy frecuentes en las personas que tienen como hobby coleccionar objetos, pero también están muy relacionados con los trastornos psicológicos señalados».

López Torrecillas añade que el coleccionismo llega a convertirse en una obsesión y, por lo tanto, en un problema para aquellos sujetos que presentan una vulnerabilidad personal, esto es, tienen falta de autoestima, escasas habilidades sociales y trastornos a la hora de enfrentarse a los contratiempos. En estos casos, el coleccionismo compulsivo ayuda a sentirse mejor.

La profesora de la UGR considera que «la excesiva presión y el bombardeo publicitario» que muchas editoriales ejercen a través de los medios de comunicación «puede propiciar que sujetos con predisposición desarrollen este problema».

Exposure to organochloride pesticides affects semen quality in youg men.

Escrito por

Two in 10 young people in South East Spain have poor sperm density, which involves requiring more time to accomplish fertilization. The most common means of exposure to pesticides is food and other household products
According to a study conducted at the University of Granada, combined exposure to organochlorides significantly alters semen quality in young people from South East Spain. Having a low number of spermatozoa taking the levels established by the World Health Organization (WHO) as a reference can delay fertilization.

The analysis was conducted by Clemente Aguilar, from the Medical Research Laboratory of the University Hospital San Cecilio, Granada, Spain, and coordinated by Marieta Fernández, Marina Lacasaña and Nicolás Olea (University of Granada), basing on a sample of 280 volunteer students aged 18-23 years from the University of Almería, Spain.

The starting point was the hypothesis that organochlorine pesticides cause alterations in semen quality parameters, as they alter homeostasis of male hipotalamus-hypophysis-gonads axis. The risk increases with exposure to different pesticides, even in low concentrations.

The results obtained showed that young people from South East Spain scores in a medium position –tending to the highest positions– with the semen quality reported in other European countries. Semen quality was measured after the total spermatic number (TSN) and the total sperm motility.

Semen quality has been found to be influenced by many factors as lifestyle –education level and job–, physical and biochemical parameters –obesity, sexual hormone levels, lipids in blood, etc– and environmental exposure.

Ingesting Pesticides Through Food
The most common means of exposure to pesticides among the general population is through food and other household products. From the 18 pesticides found in the participants’ blood, some are forbidden in Spain, as DDT, although others as the fungicide called vinclozolin –employed in vineyards and citrus groves– are legal in this country. All the samples analysed had at least one pesticide in considerable concentrations, and the average number of pesticides detected was 11, ranging between 4 and 17. Most of the participants (62%) had residues of 10-14 different pesticides in the blood.

While exposure to certain organochlorides proved to increase total spermatic number and total sperm motility levels, other pesticides have the adverse effects and are associated to a reduction in these levels. This might be due to the fact that some pesticides are considered to be slightly estrogenic endocrine disruptors –as it is the case of endosulfan sulphate, lindane and p,p-DDT–, while others combine their clearly antiadrogenic activity to a weak estrogenic activity –as it is the case of p,p-DDE and vinclozolin.

Malformations in Spermatozoa

The study proved a strong correlation between exposure to vinclozolin and malformation rates in spermatozoa. Although no evidence was found on the potential effect of vinclozolin on humans, further experimental tests should be conducted for verification.

The fact that exposure to organochloride compounds significantly affects semen quality should not be disregarded in any epidemiologic study aimed at evaluting the influence of environmental factors. However, “foreseing the final effect of pesticides on health is not easy, basically because we are exposed to multiple environmental pollutants that interact in different ways, making it difficult to foresee their final effect” –Clemente Aguilar warns.

The University of Granada researcher concludes that, to reduce or withdraw as many pesticide residues as possible from food “it is very important to wash food with water and soap, as it cuts the surface greasy film of these products, which is the part containing more residues”.

Pesticides may be linked to fewer sperm

Exposure to organochlorides — a pesticide — significantly altered semen quality in young men from southeast Spain, researchers found.

Clemente Aguilar of the Medical Research Laboratory of the University Hospital San Cecilio in Granada, Spain, and Marieta Fernandez, Marina Lacasana and Nicolas Olea at the University of Granada say the study involved 280 students ages 18-23 from the University of Almeria.

The study found 18 pesticides in the blood of the study participants — including some banned in Spain such as DDT and others legal in Spain such as the fungicide vinclozolin, used in vineyards and citrus groves.

All the study participants had at least one pesticide in considerable concentrations. The average number of pesticides detected in the blood tests was 11, the researchers say.

Exposure to some organochlorides proved to increase total spermatic number and total sperm motility levels, while other pesticides were associated with a reduction in sperm levels.

This might be due to the fact that some pesticides are considered to be slightly estrogenic endocrine disruptors — substances that interfere with natural hormones in the body responsible for reproduction, development and/or behavior, the researchers say.

The study showed a strong correlation between exposure to vinclozolin and malformation rates in spermatozoa, but further experimental tests should be conducted for verification, the researchers say.
