Introduction: Recent immunological and transgenic advances are a promising alternative using limited materials of human origin for transplantation. However, it is essential to achieve social acceptance of this therapy.Objective: To analyze the attitude of nursing students from Spanish universities toward organ xenotransplantation (XTx) and to determine the factors affecting their attitude.Materials and methods: Type of study: A sociological, multicentre, and observational study. Study population: Nursing students enrolled in Spain (n = 28,000). Sample size:A sample of 10 566 students estimating a proportion of 76% (99% confidence and precision of ±1%), stratified by geographical area and year of study. Instrument of measurement: A validated questionnaire (PCID-XenoTx-RIOS) was handed out to every student in a compulsory session. This survey was self-administered and selfcompleted voluntarily and anonymously by each student in a period of 5-10 min.Statistical analysis: descriptive analysis, Student's t test, the chi-square test, and a logistic regression analysis.Results: A completion rate: 84% (n = 8913) was obtained. If the results of XTx were as good as in human donation, 74% (n = 6564) would be in favor and 22% (n = 1946) would have doubts. The following variables affected this attitude: age (P < 0.001); sex (P < 0.001); geographical location (P < 0.001); academic year of study (P < 0.001); attitude toward organ donation (P < 0.001); belief in the possibility of needing a transplant (P < 0.001); discussion of transplantation with one's family (P < 0.001) and friends (P < 0.001); and the opinion of one's partner (P < 0.001). The following variables persisted in the multivariate analysis: being a male (OR = 1.436; P < 0.001); geographical location (OR = 1.937; P < 0.001); an attitude in favor of donation (OR = 1.519; P < 0.001); belief in the possibility of needing a transplant (OR = 1.497; P = 0.036);and having spoken about the issue with family (OR = 1.351; P < 0.001) or friends (OR = 1.240; P = 0.001). Conclusions:The attitude of nursing students toward organ XTx is favorable and is associated with factors of general knowledge about organ donation and transplantation and social interaction.

El trasplante renal es la mejor opción terapéutica en términos de supervivencia y calidad de vida para los pacientes con enfermedad renal crónica. Los pacientes trasplantados son cada vez más mayores y con más pluripatologia asociada. Los avances en inmunosupresión y en el tratamiento han hecho que los pacientes trasplantados fallezcan con el injerto renal funcionante. Existe un incremento de peso del 10% durante el primer año del trasplante, la obesidad se relaciona con la aparición de diabetes mellitus postrasplante. Con el objetivo de analizar la incidencia de obesidad y los factores de riesgo relacionados, en una cohorte de pacientes trasplantados renales realizamos un estudio observacional y prospectivo de estos pacientes, desde enero del 2014 hasta marzo del 2015, con seguimiento de 1 año. Obteniendo como resultado, que los grupos son homogéneos en sexo, tiempo en terapia renal sustitutiva pero distintos en edad. A partir de los 3 meses los pacientes con índice de masa corporal mayor a 25 presentaron mayor incidencia de diabetes mellitus post trasplante respecto al grupo de pacientes con índice de masa corporal inferior a 25.
