Conocimientos y Actitudes sobre donación de órganos en estudiantes de Ciencias de Salud en una Universidad Nacional de Lambayeque. 2019 / Knowledge and Attitudes about organ donation in students of Health Sciences from a National University of Lambayeque - 2019

Objetivo: Determinar el nivel de conocimientos y actitudes sobre la donación de órganos y xenotrasplante en estudiantes de una Universidad Nacional de Lambayeque. Métodos: El muestreo realizado fue probabilístico de tipo aleatorio simple y la muestra estuvo conformada por 100 estudiantes Universitarios. Se realizó un estudio observacional, descriptivo y transversal para evaluar los niveles de conocimiento y actitudes sobre la donación de órganos. Se aplicó una encuesta de 20 preguntas tipo clave dicotómica. Resultados: Se entrevistaron a 53 mujeres (53,0%) y 47 (47,0%) hombres. Se observó que el 76% no conocen sobre la Ley de Promoción de Donación Solidaria de Órganos y Tejidos Humanos en el Perú. Así mismo el 96% conocen los órganos y tejidos que se pueden donar, el 61% de los estudiantes han conversado sobre el tema de donación de órganos con su familia. El 76% estaría dispuesto a donar sus órganos o tejidos después de la vida, y el 88% donaría los órganos de sus familiares para salvar la vida de otro familiar. Conclusiones: En la Facultad de Ciencias Biológicas de la Universidad se observó que los conocimientos de los jóvenes sobre la donación de órganos fueron aceptables, aunque ciertos aspectos deben ser aclarados.

Objective: Determine the level of knowledge and attitudes about organ donation and xenotransplantation in students of a National University of Lambayeque. Methods: The sampling carried out was probabilistic of a simple random type and the sample was made up of 100 university students. An observational, descriptive and cross-sectional study was conducted to assess levels of knowledge and attitudes about organ donation. A survey of 20 dichotomous key questions was applied. Results: 53 women (53.0%) and 47 (47.0%) men were interviewed. It was observed that 76% do not know about the Law on the Promotion of Solidarity Donation of Human Organs and Tissues in Peru. Likewise, 96% know the organs and tissues that can be donated, 61% of the students have talked about the subject of organ donation with their family. 76% would be willing to donate their organs or tissues after life, and 88% would donate their relatives' organs to save the life of another relative's Conclusions. In the Faculty of Biological Sciences of the University it was observed that the knowledge of young people about organ donation was acceptable, although certain aspects need to be clarified.

Epidemics on networks: Reducing disease transmission using health emergency declarations and peer communication.

Understanding individual decisions in a world where communications and information move instantly via cell phones and the internet, contributes to the development and implementation of policies aimed at stopping or ameliorating the spread of diseases. In this manuscript, the role of official social network perturbations generated by public health officials to slow down or stop a disease outbreak are studied over distinct classes of static social networks. The dynamics are stochastic in nature with individuals (nodes) being assigned fixed levels of education or wealth. Nodes may change their epidemiological status from susceptible, to infected and to recovered. Most importantly, it is assumed that when the prevalence reaches a pre-determined threshold level, P * , information, called awareness in our framework, starts to spread, a process triggered by public health authorities. Information is assumed to spread over the same static network and whether or not one becomes a temporary informer, is a function of his/her level of education or wealth and epidemiological status. Stochastic simulations show that threshold selection P * and the value of the average basic reproduction number impact the final epidemic size differentially. For the Erdos-Rényi and Small-world networks, an optimal choice for P * that minimize the final epidemic size can be identified under some conditions while for Scale-free networks this is not case.

Sixty female Wistar rats were employed and divided into three experimental groups of 20 rats each. Groups were evaluated at 15, 30, and the last at 45 days after surgery. Each group was divided into four sets of five rats each. All rats were subjected to surgery; an incision of 2 x 2 cm was done on the back of each animal, removing tissue until reaching muscular fascia, where the material was applied. Nitro-furazone was employed as positive control. Test materials were AlPO added with 0.55% wt of Zn; 0.30% wt of Ca(OH)2, and AlPO added with 0.55% wt of Zn and 0.66% wt of Ca(OH)2. Finally, as negative control no material was used. The object of this work was in the first place obtension of test materials and to evaluate the healing skin process in rats using AlPO enriched with Zn and Ca(OH)2; as indicated previously. Obtained materials were characterized employing XRD. Histologic studies tested showed that best healing process of dermal tissue corresponded to rats treated with AlPO added with 0.55% wt of Zn and 0.30% wt of Ca(OH)2. Use of AlPO ceramics to repair skin has not been reported previously.

Se utilizaron 60 ratas Wistar, que fueron evaluadas a los 15, 30 y 45 días después de la cirugía. Se quitó un cuadro de piel del lomo del animal, removiendo la epidermis y la dermis hasta alcanzar la fascia muscular donde se aplicó el material de experimentación. Se usó Nitrofurazona como control positivo y ningún material como control negativo. Los materiales a probar fueron fosfatos de aluminio a los que se agregó: 0.55% en peso de Zn y 0.30% en peso de Ca(0H)2 siendo éste el material A, y 0.55% en peso de Zn y 0.66% en peso de Ca(0H)2 el material B. Se trataron cinco ratas con cada material. Los objetivos del trabajo fueron la obtención de las cerámicas a probar y la evaluación de su efecto sobre el proceso de cicatrización de piel de ratas. Los materiales obtenidos fueron caracterizados con DRX. Estudios histopatológicos probaron que los mejores procesos de cicatrización de la piel se observaron en las ratas tratadas con el material A. El uso de las cerámicas AlPO para cicatrización de piel no ha sido reportado antes.
