Abstract
INTRODUCTION Ancillary hospital personnel represent an important body of opinion because as they work in a hospital their opinion has more credibility for the general public as a result of their activity in hospitals. However, in most cases they do not have any health care training which means that their attitude could be based on a lack of knowledge or unfounded fears. OBJECTIVE To analyze the attitude toward living kidney donation (LKD) among ancillary personnel in Spanish and Latin-American hospitals and to analyze the variables that might influence such attitude. PATIENTS AND METHOD from «International Collaborative Donor Project» a random sample was taken among ancillary personnel in Spain, Mexico and Cuba hospitals. Attitude towards LKD was evaluated using a validated, anonymously filled and self-administered survey. RESULTS 951 professionals were surveyed (Spain: 277, Mexico: 632, Cuba: 42). 89% (n=850) are in favor of related kidney donation, lowering to 31% (n=289) in non-related donation. Of the rest, 8% (n=78) are not in favor and the 3% (n=23) are unsure. By country, Cubans (98%) and Mexicans (91%) are more in favour than Spanish (84%) (P=.001). The following variables are related to favourable attitude towards LKD: female sex (P=.017), university degree (P=.010), work in health services (P=.035), labour stability (P=.016), personal experience in donation and transplantation (P=.001), positive attitude toward cadaveric donation (P<.001), belief that he or she might need a transplant in the future (P<.001), positive attitude towards living liver donation (P<.001), a willingness to receive a donated living liver if needed (P<.001), having discussed the subject of organ donation and transplantation within the family (P<.001), partner's positive attitude towards the subject (P<.001), participation in voluntary type pro-social activities (P=.002) and not being concerned about possible mutilation after donation (P<.001) CONCLUSIONS: The attitude toward living related kidney donation is favourable among ancillary personnel in Spanish and Latin-Americans hospitals. Because living donation is a better source of organs than cadaveric ones, this favourable predisposition can be used as promoting agent of living donation in order to develop it in Spanish-speaking countries.

Abstract
This paper presents an optimized procedure for assessing an immune-mediated cytotoxicity, produced after the addition of human and baboon serum to transgenic porcine fibroblasts. This procedure is performed with the xCELLigence Real-Time Cell Analyzer (RTCA). The xCELLigence system measures the impedance variations in the culture media of a 96-well microelectronic plate, and shows the changes in cell number and morphology in a real-time plot. However, different factors need to be optimized before developing an RTCA assay. Thus, we studied the influence of several variables, such as the number of cells seeded, the time the cells were allowed to grow before the tests, the serum concentration and the addition of rabbit complement. The findings were confirmed by the WST-1 classical cytotoxicity test. The results showed that 7.5 × 10(3) cells seeded per well produced the adequate CI in 10 h. The area under the curve and the CImin versus concentration values showed a very high correlation index (r(2) = 0.966 and r(2) = 0.92 for the first 50 h after challenge, respectively), proving that CI variations are directly proportional to the quantity of serum added. The addition of complement resulted in lower CImin values. Therefore, both the cytolysis level with and without exogenous complement addition had to be assessed. There was a high correlation between the relative cytotoxicity assessed by WST-1 and the CI obtained by RTCA when exogenous complement was not added (r(2) = 0.827; p < 0.001). The correlation was average when rabbit complement was added (r(2) = 0.523; p = 0.046). In conclusion, culture conditions have an important influence on RTCA cytotoxicity assays.

Abstract
Hematopoietic stem cell transplantation is the accepted therapy of choice for a variety of malignant and non-malignant diseases in children and adults. Initially developed as rescue therapy for a patient with cancer after high doses of chemotherapy and radiation as well as the correction of severe deficiencies in the hematopoietic system, it has evolved into an adoptive immune therapy for malignancies and autoimmune disorders. The procedure has helped to obtain key information about the bone marrow environment, the biology of hematopoietic stem cells and histocompatibility. The development of this new discipline has allowed numerous groups working around the world to cure patients of diseases previously considered lethal. Together with the ever growing list of volunteer donors and umbilical cord blood banks, this has resulted in life saving therapy for thousands of patients yearly. We present an overview of the procedure from its cradle to the most novel applications, as well as the results of the HSC transplant program developed at our institution since 1989.

Abstract
The medical training model is currently immersed in a process of change. The new paradigm is intended to be more effective, more integrated within the healthcare system, and strongly oriented towards the direct application of knowledge to clinical practice. Compared with the established training system based on certification of the completion of a series or rotations and stays in certain healthcare units, the new model proposes a more structured training process based on the gradual acquisition of specific competences, in which residents must play an active role in designing their own training program. Training based on competences guarantees more transparent, updated and homogeneous learning of objective quality, and which can be homologated internationally. The tutors play a key role as the main directors of the process, and institutional commitment to their work is crucial. In this context, tutors should receive time and specific formation to allow the evaluation of training as the cornerstone of the new model. New forms of objective summative and training evaluation should be introduced to guarantee that the predefined competences and skills are effectively acquired. The free movement of specialists within Europe is very desirable and implies that training quality must be high and amenable to homologation among the different countries. The Competency Based training in Intensive Care Medicine in Europe program is our main reference for achieving this goal. Scientific societies in turn must impulse and facilitate all those initiatives destined to improve healthcare quality and therefore specialist training. They have the mission of designing strategies and processes that favor training, accreditation and advisory activities with the government authorities.

Abstract
INTRODUCTION Hospital personnel are a group which has an influence on the opinion of the rest of the population about healthcare matters. Any unfavorable attitude of this group would be an obstacle to an increase in organ donation. OBJECTIVE To analyze the attitude of hospital workers toward the donation of one's own organs in Spanish and Latin American hospitals and to determine the factors affecting this attitude. MATERIAL AND METHOD Eleven hospitals from the "International Collaborative Donor Project" were selected, 3 in Spain, 5 in Mexico, 2 in Cuba and one in Costa Rica. A random sample was stratified by the type of service and job category. Attitude toward donation and transplantation was assessed using a validated survey. The questionnaire was completed anonymously and was self-administered. STATISTICAL ANALYSIS Student's t-test, the χ2 test and logistic regression analysis. RESULTS Of the 2,785 workers surveyed, 822 were from Spain, 1,595 from Mexico, 202 from Cuba and 166 from Costa Rica and 79% (n=2,191) were in favor of deceased organ donation. According to country, 94% (n=189) of Cubans were in favor, compared to 82% (n=1,313) of the Mexicans, 73% (n=121) of the Costa Ricans and 69% (n=568) of the Spanish (P<.001). In the multivariate analysis, the following variables had the most specific weight: 1) originating from Cuba (odds ratio=8.196; P<.001); 2) being a physician (OR= 2.544; P<.001); 3) performing a job related to transplantation (OR = 1.610; P=.005); 4) having discussed the subject of donation and transplantation within the family (OR= 3.690; P<.001); 5) having a partner with a favorable attitude toward donation and transplantation (OR= 3.289; P<.001); 6) a respondent's belief that his or her religion is in favor of donation and transplantation (OR= 3.021; P=.001); 7) not being concerned about the possible mutilation of the body after donation (OR= 2.994; P<.001); 8) the preference for other options apart from burial for treating the body after death (OR= 2.770; P<.001); and 9) acceptance of carrying out an autopsy if one were needed (OR= 2.808; P<.001). CONCLUSIONS Hospital personnel in Spanish and Latin American healthcare centers had a favorable attitude toward donation, although 21% of respondents were not in favor of donating. This attitude was more favorable among Latin American workers and was very much conditioned by job-related and psychosocial factors.

Abstract
BACKGROUND Teachers play a fundamental role in providing information to adolescents and could influence their attitudes. OBJECTIVES To analyze the attitude of teachers toward organ donation and the concept of brain death (BD); the psychosocial variables related to attitude; and the information provided to pupils. METHODS A multicenter study was carried out using a random sample of secondary school teaching staff from 10 schools (n = 327) in the southeast of Spain. Attitude toward organ donation was assessed using a validated questionnaire that was self-administered and completed anonymously. RESULTS The questionnaire completion rate was 88% (n = 288), with 75% (n = 215) in favor of organ donation, 23% had doubts, and 2% were not in favor. Regarding the knowledge of BD, 62% (n = 179) accepted that this meant a person's death. The variables associated with a more favorable attitude included conversations with family and friends (p < 0.05); a partner's favorable opinion (OR 3.194); knowledge of the concept of BD (p = 0.006); being a blood donor (OR 8.264); and a favorable attitude toward autopsy (OR 4.716). Teachers provided information about organ donation to pupils in 16% of cases (n = 47). CONCLUSIONS Seventy-five percent of teachers are in favor of organ donation. Their attitude is affected by psychosocial factors.

Abstract
BACKGROUND "Anxious preoccupation" is a maladaptive coping strategy for patients with terminal chronic liver pathology causing psychopathologic emotional responses. The aim of this study was to identify "anxious preoccupation" as a coping strategy when faced with this disease and to investigate its relationship with emotional-type psychopathologic symptoms in patients awaiting a liver transplant (LT). METHODS A total of 63 patients awaiting an LT were evaluated. The instrument used to evaluate coping style was the Mental Adjustment to Cancer questionnaire. One of the coping scales of this questionnaire is "anxious preoccupation" (9 items). An Instrument for psychopathologic assessment was used, the SA-45 questionnaire, which assessed 9 psychopathologic dimensions: somatizations, obsessions-compulsions, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. RESULTS "Anxious preoccupation" was used as an inadequate coping style by 51% of patients when faced with the disease. Five psychopathologic dimensions were associated with this coping strategy: 1) obsessive-compulsivity: 75% of patients with "anxious preoccupation" had obsessive-compulsivity symptoms compared with 29% of patients with other coping strategies (P < .001); 2) interpersonal sensitivity: 25% vs 6%, respectively (P = .044); 3) depression: 59% vs 29% (P = .015); 4) anxiety: 75% vs 32% (P = .001); and 5) phobic anxiety: 19% vs 3% (P = .050). CONCLUSIONS More than one-half of the patients on the LT waiting list used "anxious preoccupation" as a coping style for this disease. This strategy was associated with a greater presence of emotional-type psychopathologic symptoms in these patients.

Abstract
One of the complications that can occur in pancreas transplant is a massive intestinal hemorrhage, although such a hemorrhage is very rarely caused by ulcers due to cytomegalovirus infection. Treatment is fundamentally based on relaparatomy, although in some cases interventional radiology can be an efficient alternative because it allows the exact bleeding point to be located and therapeutic embolization to be performed. In this case, a man with diabetes type 1 who was given a simultaneous kidney-pancreas transplant had an ulcer due to cytomegalovirus infection develop in the duodenal graft (in the early postoperative period), causing a severe hemorrhage in the lower part of the gastrointestinal tract that was controlled via selective embolization of a branch of the pancreaticoduodenal artery.

Abstract
Some biomedical research procedures, such as organ xenotransplantation, usually require intensive hemotherapy. Knowledge of the whole phenotype of blood donor and graft could be useful in the field of xenotransplantation. Human and simian-type categories of blood groups have been established and they can be tested by standard methods used for human blood grouping. The aim of this work was to study the incidence of non-ABO blood group systems in different species of non-human primates, which are employed in biomedical research. The phenotype of Rh, Lewis, Kidd, Kell, MNSs, Lutheran, P and Duffy antigens was investigated in olive baboon (n = 48), chacma baboon (n = 9), Guinea baboon (n = 14), Rhesus macaque (n = 38) and squirrel monkey (n = 30) by using commercial microtyping cards. Kell, Lutheran, Kidd and Duffy antigens have been detected in all species, Rh in squirrel monkey, MNSs in rhesus macaque and squirrel monkey, and Lewis in baboon and rhesus macaque. There were differences in frequency and haemagglutination scores between species regardless of their gender and age. The main differences were found in squirrel monkey when compared with baboons and macaques. This typing system provides a tool to assess the presence of antigens in animals used for experimental procedures, such as xenotransplantation and xenotransfusion.
