Background: The shortage of available transplant organs has made it necessary to search for alternatives, one of which is xenotransplantation. However, the use of animal organs could face rejection from society and the personnel involved in its implementation., Objectives: (a) to analyze the attitudes of Veterinary Degree students in six Spanish Universities towards xenotransplantation; and (b) to determine the factors that affect its acceptance., Methods: Of the 2815 students surveyed in the degree program, 2683 valid surveys were obtained. Attitudes towards organ xenotransplantation were evaluated using a validated questionnaire of organ donation., Results: If xenotransplantation was confirmed as a clinical reality, 93% (n = 2493) of those surveyed would accept a xenotransplanted organ, whilst 7% would not. If the results of xenotransplantation were worse than those obtained with human donors and it entailed more risk, 12% (n = 318) would be in favor. 56% (n = 1497) of the students would accept a xenotransplantation provisionally pending the arrival of a human organ. Attitudes towards xenotransplantation were affected by the academic year in which a student was studying, with more favorable attitudes among students in the last year (88% in first year vs. 95% in fifth year; p < .001). More favorable attitudes are also observed depending on the attitude they have towards organ transplantation, with those students being more in favor of donating their organs when they die (94% vs. 88%; p < .001)., Conclusion: Veterinary students would have a very favorable attitude toward xenotransplantation if these animal organs functioned as well as human organs. Therefore, these students could play an important role in the future promotion of this technique., (© 2023 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Making xenotransplantation socially acceptable is the first step in working toward the promotion of this potential therapy option for providing transplant organs., Objective: To analyze the attitude toward xenotransplantation among the Latin American population resident in Florida (the USA), and to determine the variables affecting this attitude., Methods: A sample of Latin American residents in the state of Florida was randomized and stratified according to nationality, age, and sex (n = 1524). Attitude was assessed using a validated questionnaire (PCID-XenoTx Rios) which was self-completed anonymously., Statistical Analysis: descriptive analysis, Student's t-test, the chi-square test, and a logistic regression analysis., Results: The questionnaire completion rate was 95% (n = 1450). If it was assumed that xenotransplanted organs functioned as well as human ones, 10% (n = 147) would be in favor, 73% (n = 1092) against, and 17% (n = 246) undecided. If the results were worse, only 2% (n = 35) would be in favor. This favorable attitude was related to country of origin (Honduras and Guatemala; P < 0.001); age (P < 0.001); sex (women; P < 0.001); marital status (married; P < 0.001); descendents (yes; P < 0.001); level of formal education (secondary education and university; P < 0.001); participation in voluntary prosocial activities (yes; P < 0.001); having spoken about donation and transplantation within the family (yes; P < 0.001); a partner's favorable attitude toward transplantation (P = 0.040); religion (catholic; P < 0.001); knowing the attitude of one's religion toward donation (yes; P < 0.001); previous experience of donation and/or transplantation (yes; P < 0.001); a belief that one might need a transplant in the future (yes; P < 0.001); and a favorable attitude toward human donation (yes; P < 0.001). The following were associated with attitude in the multivariate analysis: age (≥40 yrs; OR = 1.152); marital status (married; OR = 500); prosocial activities (yes, I participate in them; OR = 9.196. No, but I would like to; OR = 332.538); religion (catholic; OR = 2000); attitude toward deceased organ donation (in favor; OR = 2000); and previous experience of donation and/or transplantation (yes; OR = 500)., Conclusions: The attitude of Latin Americans resident in Florida toward xenotransplantation is very negative, and is determined by many psychosocial factors, mainly related to their prior attitude toward the different kinds of human organ donation., (© 2016 John Wiley & Sons A/S.

Introduction: Research into the transplantation of solid organs from animals (xenotransplantation) is generating interest and curiosity given that this could be a way of resolving the shortage in transplant organs. However, the fact is that currently xenotransplantation is far from becoming a clinical practice., Objective: To analyse the attitude of medical students from Spanish universities towards the donation of organs from animals and to determine the factors affecting their attitudes., Type of Study: A sociological, interdisciplinary, observational and multicentre study in Spain., Study Population: Students enrolled on the medical degree in Spain (n = 34 000)., Sample Size: A sample of 9598 students (a confidence level of 99% and precision of ± 1%) stratified by geographical area and academic year. Instrument of measurement: A validated questionnaire of attitude towards organ xenotransplantation (PCID-XenoTx RIOS) which was self-administered and completed anonymously., Results: A completion rate of 95.7% (n = 9275) was obtained. If the results of xenotransplantation were as good as in human donation, 81% (n = 7491) would be in favour, 3% (n = 308) against and 16% (n = 1476) undecided. The following variables affected this attitude: sex (P < 0.001); academic year (P < 0.001); discussion of transplantation with one's family (P < 0.001) and friends (P < 0.001); the opinion of one's partner (P < 0.001); the respondent's attitude towards organ donation (P < 0.001); religion (P < 0.001); and participation in altruistic activities (P < 0.001). The following variables persisted in the multivariate analysis: (1) being a female (OR = 1.794; P < 0.001); (2) academic year (OR = 2.487; P < 0.001); (3) having spoken about the issue with one's family (OR = 1.200; P = 0.019); (4) the favourable opinion of one's partner (OR = 1.526; P = 0.028); (5) an attitude in favour of donation (OR = 2.087; P < 0.001); (6) being an atheist/agnostic, (OR = 2.5; P < 0.001); and (7) a belief that one's religion is in favour of transplantation (OR = 1.317; P = 0.005)., Conclusions: Spanish medical students have a favourable attitude towards xenotransplantation. This willingness and interest could be a decisive platform for the development and strengthening of research, both for centres with a pre-clinical xenotransplantation programme and new healthcare centres., (© 2015 John Wiley & Sons A/S.

Background: It is important to find out what would be the level of acceptance of xenotransplantation in society, especially in populations where there are preclinical trials. The Latin-American population is growing in Spain, given the cultural, religious, and language similarities., Objectives: (i) to analyze attitude toward xenotransplantation in the population born in Latin America and now residing in Spain; and (ii) to establish the variables that affect this attitude., Method: A sample of Latin-American residents in Spain was obtained randomly in 2010 and stratified by the respondent's nationality (n = 1.314). Attitude was evaluated using a validated questionnaire (PCID-XenoTx Rios), which was completed anonymously and self-administered., Statistical Analysis: Student's t-test, the Chi-squared test, Fisher's exact test, and logistic regression analysis., Results: The questionnaire completion rate was 89% (n = 1.165). If it was assumed that xenotransplanted organs functioned as well as human ones, 40% were in favor, 19% against, and 41% undecided. This attitude is related to: age (P = 0.003); sex (P = 0.002); level of education (P < 0.001); descendents (P = 0.003); country of origin (P < 0.001); participation in voluntary prosocial activities (P = 0.006); having spoken about donation and transplantation within the family (P < 0.001); a partner's favorable attitude toward transplantation (P < 0.001); previous experience of donation and/or transplantation (P < 0.001); a belief that one might need a transplant in the future (P < 0.001); and a favorable attitude toward human donation, both deceased as well as living (P < 0.001). In the multivariate analysis, the following variables continue to feature as independent variables: age (older: Odds Ratio = 1.041); sex (male: OR = 1.579); level of education (university: OR = 2.770); descendents (none: OR = 2.386); a partner's attitude toward transplantation (favorable: OR = 2.262); attitude toward deceased organ donation (favorable: OR = 1.587); previous experience of donation and/or transplantation (OR = 1.519); a belief that one might need a transplant in the future (OR = 1.675); and attitude toward related living donation (in favor: OR = 4.405)., Conclusions: Latin Americans who usually reside in Spain have a more negative attitude toward xenotransplantation than the native Spanish population, and their attitude is affected by many psychosocial factors, mainly related to previous attitude toward the different types of human organ donation., (© 2013 John Wiley & Sons A/S.)

Background: Xenotransplantation is still a long way from becoming a clinical reality. However, in an emergency situation, it could be used as a bridge for replacing vital organs until the arrival of a human organ. To analyze the attitude toward xenotransplantation among hospital personnel from several hospitals in Spain and Latin America., Methods: A random sample stratified according to the type of hospital and job category (n = 2618) in 10 hospitals in three different countries: Spain (n = 821), Mexico (n = 1595), and Cuba (n = 202). A validated questionnaire (PCID-XenoTx Rios) was self-administered and completed anonymously by the respondents., Results: If the results of xenotransplantation were similar to those achieved using human donor organs, 61% (n = 1591) of the respondents would be in favor, while 9% (n = 234) would be against and 30% (n = 793) would be unsure. The analysis of the variables affecting attitude toward xenotransplantation revealed that attitude varied according to the country of reference and was more favorable among personnel in Cuban hospitals (70% a favor) than in Spanish (57%) and Mexican ones (62%; P = 0.000). However, these differences are mainly determined by job category with the physicians having the most favorable attitude. The ancillary staff, in contrast, had the least favorable attitude (76 vs. 51% respectively; P = 0.000). Of the remaining variables, attitude is significantly related to variables connected to human donation: attitude toward the different kinds of human organ donation (deceased [P < 0.001] and living [P < 0.001]), the possibility of needing a transplant oneself in the future (P < 0.001), and attitude toward donating the organs of a deceased family member (P = 0.004)., Conclusions: A third of healthcare personnel from several hospitals are not in favor of xenotransplantation. It is necessary to provide more information about the matter, especially in hospitals where there is a preclinical xenotransplantation program or where there is access to one, such as in the hospitals in this study., (© 2013 John Wiley & Sons A/S.)

Background: The organ transplant deficit is leading to an increase in the importance of solid organ xenotransplantation. However, the use of animals for human transplantation causes a certain amount of opposition in patients and the general public. The objective of this study was to analyze the attitude of patients on the kidney and liver waiting list toward xenotransplantation and the variables affecting this attitude., Methods: Patients on the kidney and liver waiting list (January 2003 - December 2005) were surveyed. Attitude toward xenotransplantation was assessed using a psychosocial questionnaire about the donation of organs of animal origin administered by a healthcare professional from the Transplant Unit., Results: A total of 373 patients were interviewed (kidney [n=214] and liver patients [n=158]). In the case of kidney patients, if the results of xenotransplantation were as effective as those attained using human organs, 76% (n=162) would be in favor. If the results were worse, only 8% (n=17) would be in favor. Two factors affected this attitude: a high level of education (P=0.007) and a positive attitude toward organ donation upon death (P< 0.001). In the case of liver patients, 67% (n=106) would be in favor if the results of xenotransplantation were as effective as those attained using human organs, decreasing to 16% (n=25) if the results were worse. Attitude toward deceased organ donation also affected the attitude of these patients (P<0.043)., Conclusions: The attitude toward xenotransplantation of patients on the kidney and liver transplant waiting list was favorable and associated with a positive attitude toward human organ donation., (© 2011 John Wiley & Sons A/S.)
