Abstract
INTRODUCTION Colorectal cancer (CRC) is the second cause of cancer-related deaths worldwide. Five-year survival rate in Spain is 57%. The most important prognostic factor is the stage of the tumor at the diagnosis. CRC can be early diagnosed, but the adherence to screening programs is low (<50%). This study aims to ascertain the influence of social support and stressful life events on the adherence to the population screening of CRC with fecal occult blood test in Spanish average risk population. METHODS Multicenter case-control study. We conducted a simple random sampling among individuals invited to participate in the colorectal cancer screening program. We analyzed epidemiological and social variables associated with lifestyle and behavioral factors. We performed a descriptive and a bivariant analyses and a logistic regression analysis. RESULTS Four hundred and eight patients (237 cases and 171 controls) were included. Multivariant analyses showed independent association between higher adherence to the screening program and older age (OR: 1.06; 95% CI: 1.01-1.10), stable partner (OR: 1.77, 95% CI: 1.08-2.89) and wide social network (OR: 1.68; 95% CI: 1.07-2.66). Otherwise, lower adherence was associated to perceiving barriers to participate in the program (OR: 0.92; 95% CI: 0.88-0.96). We find a statistically significant association between lower adherence and high impact stressful life events in the bivariant analyses, and the tendency was maintained (OR: 0.63, 95% CI: 0.37-1.08) in the multivariant. CONCLUSION Social variables decisively influence the adherence to colorectal cancer screening. The implementation of social interventions that improve social support, reduce impact of stressful life events and the design of screening programs that decrease the perceived barriers, will contribute to increase the participation on these programs. Secondary, the colorectal cancer diagnosis will be made in early-stages with the consequent mortality reduction.

Abstract
BACKGROUND Colorectal cancer is the second cancer-related cause of death in the world. Tumour stage at diagnosis is the principal prognosis factor of survival. However, the participation in the programme is around 50%. The aim of the study was to identify the benefits and barriers perceived by the population when participating in a colorectal cancer screening programme with faecal occult blood test. METHODS We carried out a cases-controls study with 408 participants. We analyzed epidemiological and social variables associated with lifestyle and behavioural factors based in the Health Belief Model. We conducted a descriptive analysis, and identified variables associated to adherence by a logistic regression. RESULTS Variables independently associated with the participation in a colorectal cancer screening programme were age (OR 1.06; 95% CI: 1.01-1.11), having a stable partner (OR 1.96; 95% CI: 1.20-3.18), the level of education (OR 1.59; 95% CI: 1.02-2.47) and two of the barriers to participate in the faecal occult blood test screening: "you don't know how to do one" (OR=0.46; 95% CI: 0.23-0.93) and "it is not that important right now" (OR=0.43; 95% CI: 0.24-0.78). CONCLUSION The existing barriers for screening with faecal occult blood test are the best factor predicting. This is relevant when designing the intervention programmes, as they should focus on reducing perceived barriers to increase the participation in colorectal cancer screening, thereby reducing colorectal cancer mortality.

Abstract
OBJECTIVE To assess moral distress (MD) among Spanish critical care healthcare professionals (HCPs). DESIGN Cross-sectional, prospective study. SETTING ICUs in Spain. PARTICIPANTS HCPs currently working in Spanish ICUs. INTERVENTIONS A 55-item questionnaire was electronically distributed. MAIN VARIABLES The questionnaire included work-related and socio-demographic characteristics, the Spanish version of the Measure of Moral Distress for Health Care Professionals (MMD-HP-SPA), and the Hospital Ethical Climate Survey (HECS). RESULTS In total, 1065 intensive care providers completed the questionnaire. Three out of four validity hypotheses were supported. MD was significantly higher for physicians (80, IQR 40-135) than for nurses (61, IQR 35-133, p=0.026). MD was significantly higher for those clinicians considering leaving their position (78, IQR 46-163 vs. 61, IQR 32-117; p<0.001). The MMD-HP-SPA was inversely correlated with the HECS (r=-0.277, p<0.001). An exploratory factor analysis revealed a four-factor structure, evidencing the patient, team, and system levels of MD. CONCLUSIONS In the study sample, Spanish intensivists report higher MD than nurses. Strategies to improve ICU ethical climate and to correct other related factors in order to mitigate MD at a patient, team, and system level should be implemented. Both groups of HCPs manifest a relevant intention to leave their position due to MD. Further studies are needed to determine the extent to which MD influences their desire to leave the job.

Abstract
INTRODUCTION Colorectal cancer 5-years-survival is 57%, partway due to a low rate of participation in screening programmes. Instruments analyzing causes of low adherence are needed. OBJECTIVE To evaluate the validity and internal consistency of the Spanish version of Rawl's Questionnaire for the screening of colorectal cancer by faecal occult blood testing. TYPE OF STUDY Questionnaire validation methodology. LOCATION Three Primary Care Centres in Valencia. VARIABLES Age, sex, civil status, educational level, social class, smoking, alcohol consumption, body mass index, personal and family history of cancer. RESULTS We analyzed 408 individuals (237 cases and 171 controls). Mean age was 59.45 years (SD 5.17). Internal consistency of all variables reached a Cronbach's alfa of 0.796. The Cronbach's alfa benefit dimension of the screening was 0.871 and for the barrier dimension of the screening it was 0.817. Intraclass correlation coefficients of the test-retest for the benefit dimension of the screening was 0.809 (CI 95% 0.606-0.913) and 0.499 (CI 95% 0.126-0.750) for the barrier dimension. CONCLUSION The Spanish version of Rawl's Questionnaire is valid, reliable and reproducible, so we have this validated instrument with which to identify barriers and benefits in a colorectal screening programme in Spain.

Abstract
The mycobiotic component of the microbiota comprises an integral, yet under-researched, part of the gastrointestinal tract. Here, we present a preliminary study of the possible contribution of gut mycobiota to sub-clinical atherosclerosis in a well-characterised group of obese and non-obese subjects in association with the Framingham Risk Score (FRS) and carotid intima-media thickness (cIMT). From all taxa identified, the relative abundance of the phylum Zygomycota, comprising the family Mucoraceae and genus Mucor, was negatively associated with cIMT and this association remained significant after controlling for false discovery rate. Obese subjects with detectable Mucor spp. had a similar cardiovascular risk profile as non-obese subjects. Interestingly, the relative abundance of Mucor racemosus was negatively associated both with FRS and cIMT. Partial least square discriminant analyses modelling, evaluating the potential relevance of gut mycobiota in patients stratified by mean values of cIMT, showed that even a 1 component model had a high accuracy (0.789), with a high R2 value (0.51). Variable importance in projection scores showed that M. racemosus abundance had the same impact in the model as waist-to-hip ratio, high-density lipoprotein-cholesterol, fasting triglycerides or fasting glucose, suggesting that M. racemosus relative abundance in the gut may be a relevant biomarker for cardiovascular risk.

Abstract
UNLABELLED Determine the prevalence of malnutrition in valid adults older than 75 years old in Xinzo (Spain), and study institutionalization as a possible risk factor of malnutrition. METHODS This is a cross-sectional study of prevalence. SAMPLE 311 people over 75 years. VARIABLES STUDIED Age, gender, marital status, education level, institutionalization or not, nutritional status (MNA and anthropometric parameters), social support (Duke- Unc scale), Quality of life (Euro- Quol scale); associated diseases, swallowing problems, type of diet and medications. RESULTS The median age was 82.55 years (SD: 4.83), 51.8% were women. The 52.7% were married, regarding the educational level, 76.8% had completed the primary education. The 17.4% were institutionalized. The median of pathologies was 3 (SD:1.42 and the number of drugs for individual was 4 (SD:2.44). The 54.70% lived with another family or partner. The median of quality of life was 6.84. According to the results of the MNA did not find any case of malnutrition, but a 20.3% of patients present values of risk. Multivariate analysis found relationship between the presence or not of malnutrition and the institutionalization OR = 0.403 (95% CI: 0.186-0.872), the number of pathologies OR = 1.301 (95% CI: 1.032-1.641), quality of life OR = 1.401 (95% CI: 1.145-1.716). CONCLUSION Our valid elders are well nourished. The age, a good quality of life and a good support are protective factors. The risk of malnutrition is associated to a higher age, to institutionalization and to higher number of pathologies.

Abstract
Dengue (family Flaviridae, genus Flavivirus, DENV) and dengue hemorrhagic fever (DHF) are presently important public health problems in Costa Rica. The primary strategy for disease control is based on reducing population densities of the main mosquito vector Aedes aegypti (L.) (Diptera: Culicidae). This is heavily dependent on use of chemical insecticides, thus the development of resistance is a frequent threat to control program effectiveness. The objective of this study was to determine the levels of insecticide resistance and the metabolic resistance mechanisms involved in two Ae. aegypti strains collected from two provinces (Puntarenas and Limon) in Costa Rica. Bioassays with larvae were performed according to World Health Organization guidelines and resistance in adults was measured through standard bottle assays. The activities of beta-esterases, cytochrome P450 monooxygenases, and glutathione S-transferases (GST), were assayed through synergists and biochemical tests, wherein the threshold criteria for each enzyme was established using the susceptible Rockefeller strain. The results showed higher resistance levels to the organophosphate (OP) temephos and the pyrethroid deltamethrin in larvae. The efficacy of commercial formulations of temephos in controlling Ae. aegypti populations was 100% mortality up to 11 and 12 d posttreatment with daily water replacements in test containers. Temephos and deltamethrin resistance in larvae were associated with high esterase activity, but not to cytochrome P450 monooxygenase or GST activities. Adult mosquitoes were resistant to deltamethrin, and susceptible to bendiocarb, chlorpyrifos, and cypermethrin. Because temephos and deltamethrin resistance are emerging at the studied sites, alternative insecticides should be considered. The insecticides chlorpyrifos and cypermethrin could be good candidates to use as alternatives for Ae. aegypti control.

Abstract
Aedes aegypti (L.) (Diptera: Culicidae) control programmes in Cuba rely on the application of the organophosphate temephos for larval control. Hence, the monitoring of resistance to this insecticide is an essential component of such programmes. Here, 15 field populations from different municipalities of Havana City were assayed for resistance to temephos. High levels of resistance were detected in all strains and resistance ratios were highly correlated with esterase activity (P = 0.00001). Populations from three municipalities were tested in both 2006 and 2008; resistance and esterase activities both significantly increased during this 2-year period. Synergist studies demonstrated that neither glutathione transferases nor monooxygenases were associated with the increase in resistance to temephos in this period. The duration of the efficacy of commercial formulations of temephos in controlling Ae. aegypti populations in Havana City was reduced by the high level of temephos resistance observed; hence these data are of clear operational significance for the dengue control programme in Cuba. New integrated strategies to avoid further increases in temephos resistance in Cuba are necessary.

Abstract
Serial blood sampling before and after exposing four anovular Corriedale ewes to a group of rams and estrous ewes during the non-breeding season revealed a pattern of LH secretion similar to that previously observed in Merinos. Mean LH values doubled (P<0.001) from 0.24+/-0.06 microgL(-1) (mean+/-s.e.m.) before to 0.55+/-0.05 microgL(-1) after 2h of visual, auditory, and odor exposure to rams and estrous ewes in an indoor facility. A non-significant (P<0.17) increase of LH pulses per hour was also observed (0.7+/-0.3 pulses per hour before compared with 1.3+/-0.3 during stimulation). All four ewes had recently formed corpora lutea by five days after stimulation. Results are consistent with the pattern of sudden increase and sustained release of LH observed in other sheep breeds, particularly the Merino.

Abstract
UNLABELLED Living liver donation is becoming a more widely accepted practice given the decrease in donor morbidity and mortality and the beneficial results in the recipient. Use of this technique is unusual in Spain. There are a number of workers against its use within the health care system. The objective of this study was to analyze attitudes toward and the variables that affect them concerning living liver donation among surgical services in a transplant hospital. MATERIALS AND METHODS A random survey was stratified by surgical area and job category in a Spanish third-level hospital with an ongoing solid organ transplant program. Attitudes toward living liver donation were assessed using a questionnaire about organ donation and transplantation that evaluated various psychosocial variables. Student's t test and the chi square test were used. RESULTS A total of 263 workers were surveyed (mean age as 40 +/- 9 years). Regarding attitudes toward living liver donation, the level of acceptance was 80% (n = 211) of respondents, whereas 10% were undecided (n = 26), and another 10% were against (n = 26), assuming that the donations were related. When we asked about unrelated living donation, the percentage in favor decreased to 10% (n = 27). No differences were found with respect to job category or type of service. The variables that are related to such an attitude are the following: (1) possibility of respondent needing an organ (P = .001); (2) favorable attitude toward living kidney donation (P < .000); and (3) a belief that medical errors exist (P = .004). An important finding was that attitudes toward living liver donation were not more favorable according to whether the respondent was in favor or against cadaveric organ donation (P = .175). CONCLUSION There was a highly favorable attitude toward living liver donation among hospital personnel in surgical services, which is an important factor to take into account if this type of donation is to be encouraged in Spain.

Abstract
INTRODUCTION There has been an increase in the population resident in southeast Spain originating from the British Isles, among them Irish citizens. Living kidney donation rates are currently low in Spain. In an attempt to increase these rates, a search is underway to find groups who are favorable toward this type of donation especially from those countries with high levels of living kidney donation. The objective of this study was to analyze the attitudes toward living kidney donation among the population group originating from Ireland (including Northern Ireland) and who live in southeast Spain. MATERIALS AND METHODS A random sample (n = 325) of the population in southeast Spain (Autonomous Community of Murcia) who were born in Ireland completed a validated questionnaire to measure attitudes. The questionnaire was self-administered and was completed anonymously between November 2005 and March 2006. Spanish citizens from an urban and a rural area were used as control groups (n = 500). RESULTS The questionnaire completion rate was 81% (n = 262) including 87% (n = 229) of respondents in favor of living related donation and 13% (n = 94) against it. The attitude was similar to that of the urban Spanish control group (87% vs 89%; P = .5832) and more favorable than that of the rural area (87% vs 29%; P < 0.001). With respect to living donation for monetary incentives, 7% (n = 16) reported that they would donate an organ while alive for money, although this would depend on the quantity of money offered; 4% (n = 10) would need to think about it; while the vast majority (81%; n = 212) would never donate an organ in life for money. The following variables influenced attitudes toward living kidney donation: respondent sex (P = .023); previous experience with the donation and transplantation process (P = .004); participation in prosocial activities (P = .016); religion (P = .003); partner's attitude toward the matter (P = .020); concern about "mutilation" after donation (P < .001); and belief that living kidney donation is a risk for the patient (P = .003). CONCLUSION Irish citizens living in southeast Spain showed a favorable attitude toward related living kidney donation. Therefore, they are a priority group to whom the option of living kidney donation should be offered when a kidney transplant is needed by an Irish person.

Abstract
In Spain, despite its high rate of cadaveric donation, death while on the liver transplant waiting list is high. For this reason, living liver donation is being encouraged despite of the risk of morbidity for the donor. The objective of this study was to analyze attitudes toward living liver donation among hospital personnel in a hospital with a recently authorized living donor liver transplantation program. A random sample was taken and was stratified by type of service and job category (n = 1,262). Attitude was evaluated by means of a validated psychosocial questionnaire. The questionnaire was completed anonymously and was self-administered. Statistical analysis included the Student t test, the chi(2) test, and logistical regression analysis. The questionnaire completion rate was 93% (n = 1,168). Only 15% (n = 170) of respondents were in favor of living liver donation if it were unrelated. An additional 65% (n = 766) were in favor if this donation, but only for relatives. Of the rest, 9% (n = 107) did not agree with living liver donation, and the remaining 11% (n = 125) were undecided. The variables related to this attitude were age (P = 0.044); job category (P = 0.002); type of service (according to whether it is related to organ donation and transplantation) (P = 0.044); participation in prosocial activities (P = 0.026); attitude toward cadaveric organ donation (P <0.001); attitude of a respondent's partner toward organ donation (P = 0.010); a respondent's belief that in the future, he or she may need a transplant (P < 0.001); and a willingness to receive a donated living liver organ if one were needed (P < 0.001). There is also a close relationship between attitude toward living kidney donation and living liver donation (P < 0.001). In the multivariate analysis, the only common independent variable from the bivariate analysis was a willingness to receive a living donor liver transplant if one were needed (odds ratio = 9.3). Attitude toward living liver donation among hospital personnel in a hospital with a solid organ transplant program is favorable and is affected by factors related to cadaveric donation, altruistic activity, and feelings of reciprocity. Physicians and the youngest hospital workers are those who are most in favor, which leads us to think that there is a promising future for living liver transplantation, which is essential given the cadaveric organ deficit and the high mortality rate while on the waiting list.

Abstract
In 1993, a fraction of antibodies (Abs) devoid of L chain was found naturally occurring in the Camelidae. They were found to lack L chains, as well as the first constant heavy-chain domain (CH(1)) and therefore they were named "heavy-chain Abs" (HCAbs). Subsequent studies focused on the functional, structural and biochemical properties of recombinant variable fragments (rVHHs) of HCAbs. It was stated that rVHHs have an augmented capacity to interact with "partially hidden" epitopes, like enzymes active sites, and have an increased stability to thermal and chemical aggression. It has been suggested that these unconventional Abs could represent an evolutionary advantage, being more efficient than conventional Abs to inhibit microbial enzymes, and thus exerting a more protective immune response against pathogens. The present work focuses on the immunobiological role of HCAbs, in their capacity to inhibit microbial enzymes. Two animal models were selected, comprising a model for common vertebrates without HCAbs (rabbits), and a model for vertebrates with both conventional and unconventional Abs (Lama glama). A recombinant bacterial beta-lactamase (CTX-M-2) was selected as the microbial enzymatic antigen. After conventional immunization schedules, neither serum titers nor serum inhibitory capacity showed significant differences when rabbits and llamas were compared. These results indicate that the a priori assumption that the adaptive immune system of camelids could be better "prepared" to respond to bacterial enzymes because of the presence of HCAbs, is not always accurate. Furthermore, when the different llama antibody isotypes and subclasses were purified, it was demonstrated that the inhibitory capacity of total serum was due exclusively to IgG(1). HCAbs not only failed to inhibit CTX-M-2, but instead they activated its enzymatic activity. Altogether, these results indicate that the hypotheses extrapolated from the rVHHs properties need to be revised; the real role of HCAbs in vivo remains unknown, as well as their evolutionary cause.

Abstract
INTRODUCTION The attitude of health-care personnel is fundamental for the procurement of transplant organs, especially in those services that are related to transplantation. The objective of this study is to find out the attitude towards living liver donation among personnel who work in transplant-related services in a hospital with a cadaveric and living organ transplant programme. MATERIALS AND METHODS A random sample was taken and stratified by type of service and job category (N=330), in services related to transplantation (procurement units, transplant units and follow-up units). Attitude was evaluated using a validated psychosocial questionnaire. CONTROL GROUP a random sample of personnel in clinical services that do not have any direct contact with solid organ transplantation. Student's t-test and the chi(2) test complemented by a logistical regression analysis were applied in the statistical analysis. RESULTS The questionnaire completion rate was 94% (N=309). Only 10% (N=31) of respondents are in favour of living liver donation if it is unrelated, but another 67% (N=207) are in favour if donation were for a relative. Of the rest, 11% (N=33) do not agree with living liver donation and the remaining 12% (N=38) are undecided. In the control group, attitude towards living liver donation is favourable in 82% (N=344) (P=0.0908). An analysis of the variables that influence attitude shows that the following factors are significantly related: (1) age (P=0.037); (2) a respondent's belief that he or she may need a transplant in the future (P=0.013); and (3) if it were necessary, a willingness to receive a donated living liver organ (P=0.000). Of the variables that have the most influence on attitude towards living liver donation in the bivariate analysis, there are two variables that are statistically significant in the multivariate analysis: (1) age and (2) willingness to accept a donated living liver organ from a relative if it were needed (OR=14.19). There is also a close relationship between attitude towards living liver donation and attitude towards living kidney donation (P=0.000) CONCLUSIONS: There is a favourable attitude towards living liver donation among personnel in units related to the transplantation and donation process, although it is less favourable than expected. Therefore, it will be necessary to increase this level of acceptance and to improve information about the matter if we want to encourage living liver donation. The youngest workers in these units are those who are most in favour, which leads us to believe that there is a hopeful future for this type of liver donation that is so necessary given the cadaveric organ deficit.

Abstract
BACKGROUND It is important to find out about the social acceptance of xenotransplantation, especially in populations where there are pre-clinical xenotransplantation projects, and therefore the possibility of xenotransplantation to humans. In the native population of southeastern Spain this situation is well-known, but in recent years there has been an important social change because of a considerable migrational flow into Spain, especially from the British Isles. OBJECTIVE To analyze the attitude toward xenotransplantation among the population living in southeastern Spain born in the British Isles and to determine the variables that affect this attitude. METHOD A random sample was taken of British and Irish citizens resident in southeast Spain and stratified according to a respondent's nationality (n = 1700). The data were obtained between November 2005 and April 2006. Attitude was evaluated using a validated questionnaire that was completed anonymously and self-administered. The control group comprised a random sample (n = 250) of the native population. Student's t-test, the chi-squared test, Fischer's exact test and a logistic regression analysis were used in the statistical analysis. RESULTS The questionnaire completion rate was 91% (n = 1546), with 69% of respondents in favor of xenotransplantation, 8% against and 23% unsure, an attitude that is similar to that of the control group (P = 0.1616). These attitudes were based on the assumption that transplanted animal organs had the same outcomes and involved the same risks as human ones. This attitude is related to the following factors: (i) being of male sex (P = 0.0477); (ii) level of education (P = 0.012); (iii) being natives from England or Wales (P = 0.016); (iv) participation in voluntary pro-social activities (P = 0.035); (v) the respondent's religion (P < 0.001); (vi) knowing that one's religion has a favorable attitude toward transplantation (P < 0.001); (vii) having discussed the subject of organ donation and transplantation within the family (P < 0.001); (viii) a partner's favorable attitude toward transplantation (P < 0.001); (ix) previous experience of donation or transplantation (P = 0.024); (x) the belief that in the future one might need a transplant (P = 0.007) and (xi) a favorable attitude toward human donation, both deceased and living (P < 0.001). In the multivariate analysis, the following are significant independent variables: sex [odds ratio (OR) = 2.206], a favorable attitude toward deceased donation (OR = 1.977), and attitude toward living donation (OR = 2.097). CONCLUSIONS Attitude toward xenotransplantation among British residents who usually live in the southeast of Spain is similar to that of the native Spanish population, and is determined by many psychosocial factors, mainly related to previous attitude toward the different types of human organ donation and the respondent's sex.

Abstract
INTRODUCTION A considerable number of professionals who work in a hospital could be against organ donation, which means that when the time comes, they could act as an obstacle to donation. The objective of this study was to analyze the attitude of hospital professionals toward organ donation and to determine the factors that influence this attitude in a Spanish center with a transplant program. MATERIALS AND METHODS The study was carried out in a third-level Spanish hospital with a solid organ transplant program. A random sample was taken (n = 1262) and stratified by job category and type of service. Attitude was evaluated using a validated questionnaire. Contact was made in each service with the person responsible for each of the job categories in order to distribute the survey. The survey was completed anonymously and was self-administered. Student's t-test, the chi-squared test, and logistic regression analysis were applied in the statistical analysis. RESULTS The survey completion rate was 93% (n = 1168). Most respondents were in favor of donation [69% (n = 808)]. Of those who are not in favor, 29% (n = 105) provide fear of apparent death as the reason whilst most do not give a reason (negative assertion; 57%; n = 206). There are many factors related to this attitude toward donation, which are evident in the multivariate analysis: (i) job category, in which physicians are twice as likely to be in favor of donation than ancillary personnel (OR = 2.02); (ii) a respondent's knowledge of brain death (OR = 1.64); (iii) having discussed the matter of organ donation and transplantation within the family (OR = 1.89); (iv) a preference for other options apart from burial (OR = 3.66); (v) being in favor of the performance of autopsy if it were necessary (OR = 2.76); (vi) not being concerned about mutilation of the cadaver (OR = 2); and (vii) having a partner with a favorable attitude toward donation (OR = 2.2). CONCLUSIONS Attitude toward cadaveric organ donation among personnel in a transplant hospital is similar to that described in the general public and is determined by many factors. The following factors are most noteworthy: (i) job category; (ii) knowledge of the concept of brain death; (iii) consideration of the matter of donation in the family; and (iv) fear of manipulation of the cadaver. In view of this attitude, which is similar to that of the general public, it is necessary to carry out promotion activities if we want to increase cadaveric donation rates.

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. The objective of this study is to analyze the attitude toward living liver donation among ancillary personnel in a hospital with a cadaveric and living liver organ transplant program and to analyze the variables that might influence such attitude. PATIENTS AND METHOD A random sample was taken which was stratified by service (n=401) among ancillary personnel in the hospital. Attitude was evaluated using a survey that was validated in our geographical area. A representative from each service was contacted. This person was given an explanation of the study and was made responsible for the distribution of the questionnaire in selected work shifts. The survey was completed anonymously and was self-administered. The c2 test, Student s t-test and logistical regression analysis were used in the statistical analysis. RESULTS The questionnaire completion rate was 94% (n=377). Of all the respondents, 20% (n=74) are in favor of donating a living hemi-liver, but an additional 62% (n=233) are in favor if donation is for a relative. Of the rest, 8% (n=30) do not accept this type of donation and the remaining 11% (n=40) are unsure. The following variables are related to attitude toward living liver donation: attitude toward cadaveric donation (p=0.002); a respondent s belief that he or she might need a transplant in the future (p<0.001) and a willingness to receive a donated living liver if one were needed (p<0.001). In the multivariate analysis the following have been found to be significantly related variables: a) a respondent s belief that he or she might need a transplant in the future (OR=1.5); and b) a willingness to receive a living donated kidney if one were needed (OR=16.2). CONCLUSIONS Attitude toward living liver donation is fairly favorable among ancillary personnel in a transplant hospital and is not affected by the psychosocial factors found to be related to attitude toward donation in previous studies. However, if we want to encourage this type of transplantation with living donors it will be necessary to carry out informative campaigns to raise awareness within the hospital.

Abstract
Between the April and December of 2004, an Aedes aegypti (L.) pupal/demographic survey was conducted in the Playa municipality of Havana. The aims were to identify the key types of container in the production of the adult mosquitoes (and so provide a basis for targeted control) and assess transmission risk in terms of the number of pupae/person. Pupal abundance, as measured in the survey, was compared with traditional Stegomyia indices. The immature stages of Ae. aegypti were only found in 70 of the 15,153 containers that were investigated and the pupae of this species were only seen in 52 of the containers. Ground-level water-storage tanks yielded 74.1% of all the pupae, with a further 19.0% found in miscellaneous small containers. The utility of the pupal/demographic-survey methodology in the evaluation of dengue risk in the study area, and other areas of Cuba with low densities of Ae. aegypti, is discussed.

Abstract
BACKGROUND In situations of extreme urgency when there is a need for vital organs, xenotransplantation could provide a bridge until the arrival of a human organ. However, it is important to find out the level of acceptance of this potential therapy among the health care workers who would be involved in its implementation. The objective of this study is to analyze attitude among personnel in a hospital with a pre-clinical xenotransplantation program toward xenotransplantation and to determine the variables that influence this attitude. MATERIALS AND METHODS A random sample (n=1168) was taken and stratified according to job category and service. Attitude toward xenotransplantation was evaluated using a validated questionnaire. Contact was made with the head of each service who was given an explanation of the project. This person was made responsible for the distribution and collection of the survey in each service in randomly selected work shifts. Such a survey was completed anonymously and was self-administered. A random sample of 250 individuals from our regional community was used as a control group. RESULTS The survey completion rate was 98% (n=1148). Most respondents are in favor (67%), 7% are against and 26% undecided. Such an attitude is more favorable in the control group (74% vs. 67%; P=0.0378). The following factors are positively related to such an attitude: (1) male sex (P<0.0005); (2) a younger age (P=0.013); (3) participation in prosocial voluntary activities (P=0.002); (4) knowing that the church has a positive attitude toward donation and transplantation (P<0.0005); (5) a partner's favorable attitude toward transplantation (P<0.0005); (6) a physician's job category (P<0.0005); (7) a resident physician's job contract situation (P=0.017); (8) a respondent's belief that he or she may need a transplant in the future (P<0.0005); and (9) a favorable attitude toward human donation, whether this be cadaveric or living (P<0.0005). In the multivariate analysis, the following persist as independent variables: (1) sex (odds ratio=1.6); (2) participation in prosocial voluntary activities (odds ratio=2.2); (3) a partner's unfavorable attitude toward transplantation (odds ratio=0.3); (4) a favorable attitude toward cadaveric donation (odds ratio=2); and (5) attitude toward living liver donation (odds ratio=3.8). CONCLUSIONS Attitude toward xenotransplantation is not as favorable among hospital personnel as it is in the general public and this is determined by many factors. It will be necessary for research groups to periodically carry out awareness-raising activities about our findings in our own centers, to avoid the rejection that could be generated by a lack of awareness.

Abstract
The attitude of health-care workers, especially in transplant-related services, is fundamental in the process of organ procurement. In this study we examine the attitude of workers in transplant-related services toward cadaveric organ donation and transplantation (ODT) in a third-level hospital in Spain. A random sample was stratified according to type of service and job category (n = 309) among personnel in transplant-related services (organ procurement units, transplant units and follow-up units). Attitude toward cadaveric organ donation was evaluated using a validated psychosocial questionnaire. Seventy percent (n = 215) of respondents were found to be in favor of donation, as opposed to 30% against or undecided (n = 94). Regarding job category, attitude was most favorable among physicians (86%, n = 99; p = 0.000). With respect to type of service, attitude tended to be more negative in organ procurement units and more positive in the follow-up units of transplanted patients (41% vs 81%, p = 0.013). Upon analysis of the psychosocial variables, significant results were found with respect to the following factors: (1) age (39 vs 42 years, p = 0.007); (2) having discussed ODT with family members or with a partner (p = 0.007); (3) understanding of the concept of brain death (p = 0.001); (4) attitude toward carrying out an autopsy (p = 0.001); and (5) concern about the possibility of mutilation after organ extraction. Attitude toward cadaveric donation was lower than expected among personnel in transplant-related services, especially among ancillary personnel and workers in organ procurement units.

Abstract
OBJECTIVE The deficit in transplantable organs is making it necessary to find alternative sources. One possibility is xenotransplantation. However, the use of animal organs may be rejected by society and among health professionals. Primary Care is fundamental for promoting matters of health; in Spain it has access to nearly 100% of the population. Our objective was to analyze the acceptance of this therapy, although it is experimental, among Primary Care professionals, given that they are the ones most involved in spreading information about this therapy if it was confirmed to be useful. MATERIALS AND METHODS A random sample was stratified by sex, job category, and geographical location among Primary Care personnel, including 428 professionals in 32 health centers among population of 2851 professionals. Attitudes toward xenotransplantation were evaluated using a questionnaire on psychosocial attitudes validated in our geographical area. Contact was made in each center with the Doctor Coordinator for doctors, the Nursing Coordinator for nurses, and an Administrative Officer for ancillary personnel. The chi-square test and Student t test were applied to evaluate categorical and continuous data, respectively. RESULTS Attitudes toward xenotransplantation were similar to those obtained in human organs: favorable in 79% (n = 325), whereas 19% (n = 78) had doubts and 2% (n = 10) were against. The attitude was more favorable in men (89% vs 72%; P < .000), those who had cared for transplant patients (84% vs 71%; P = .009), those with previous experience in organ donation and transplantation (84% vs 75%; P = .033), those with an attitude in favor of cadaveric organ donation (83% vs 66%; P < .0001), and those in favor of living donation of the kidney (P < .000) or the liver (P < .000), as well as those who believed that they may need a transplant at some time in the future (84% vs 74%; P = .045). There was a clear difference in attitude according to job category (P = .018): approval rates were 89% for doctors, 76% for nurses, and 70% for ancillary personnel. CONCLUSIONS Attitudes toward future application of xenotransplantation were quite positive among doctors. However, the attitudes of nursing and ancillary personnel were similar to those of the general population. The main factors related to such an attitude depended mainly on the previous relationship and attitude of the respondent toward human organ donation and transplantation.

Abstract
OBJECTIVE The attitudes of health care personnel, specifically doctors, have a significant influence on public attitudes toward organ donation and transplantation. The objective herein was to analyze the attitudes of Primary Care (PC) doctors toward living organ donation and to determine the psychosocial factors that condition these attitudes. MATERIALS AND METHODS A random sample was stratified by geographical location (six health areas in our community) among PC doctors, including 155 respondents from 32 health centers. Attitudes toward donation were evaluated using a psychosocial questionnaire validated in our geographical area. Contact was made with the Doctor Coordinator in each center for distribution of the questionnaires, which were completed anonymously. The chi-square test and Student t test were applied to evaluate the data. RESULTS When the living donor is not related, only 21% (n = 32) of PC doctors were in favor of living kidney donation, and only 20% (n = 31) for living liver donation (P > .05). In contrast, these percentages were 90% and 89% in favor of kidney and liver related donation, respectively. Upon analysis of the psychosocial variables affecting these attitudes, there was only an association with their partner's opinion (P = .009 for kidney and P = .000 for liver), and the possibility of needing a transplant oneself (P = .000). CONCLUSIONS PC doctors have favorable attitudes toward related living donation. If living donation is promoted by transplant coordination units, such PC professionals could act as a source of positive information about the matter for the general public.

Abstract
OBJECTIVE To reduce the number of family organ donation refusals, it is necessary not only to act on the general public but also on the health care system. In this respect, there are data suggesting that the percentage of hospital personnel against donation is high, especially among ancillary personnel. The objective herein was to analyze the attitudes of ancillary hospital professionals toward donation of their own organs and determine factors that conditioned such attitudes. MATERIALS AND METHODS A random sample in a third-level hospital with a solid organ transplant program was stratified by ancillary services: administrative, porters, maintenance, cleaning, and cooking. Attitudes toward donation of one's own organs after death were evaluated using a questionnaire on psychosocial aspects validated in our area. It included various psychosocial variables that could affect such attitudes. The Student t test and chi-square test were used to evaluate the data. RESULTS We analyzed 277 respondents of mean age 43 +/- 8 years and 96% women. The level of acceptance of organ donation was 64% (n = 178), whereas 46% were either against or undecided (n = 98). The variables which determined the attitudes were understanding of brain death (P = .004); attitude toward cadaveric manipulation, especially toward autopsy (P = .013) and cremation (P = .004); concern about mutilation after donation (P = .014); religion (P = .032); partner's attitude toward donation (P < .0001); and possibility of needing an organ in the future (P = .031). CONCLUSIONS Ancillary hospital personnel had similar attitudes toward donation as those of the general public as observed in other studies. The attitudes were determined by many psychosocial factors. A campaign to raise awareness among professionals has become a priority, given that working in a hospital, their unfavorable attitude could have a strong negative impact on the general public.

Abstract
OBJECTIVE Our aim was to analyze acceptance of cadaveric and living organ donation for transplantation among resident doctors, given that they are the new professionals of medicine who will have to encourage and develop transplant programs. MATERIALS AND METHODS A random survey was performed on resident doctors in a third-level hospital with an organ transplant program which is accredited for undergraduate and postgraduate education (n = 171). Attitudes toward cadaveric and living donation were evaluated using a questionnaire including various psychosocial variables that might affect such attitudes. We used the Student t test and the chi-square test. RESULTS The sample was composed of responses by 171 resident doctors of mean age 28 +/- 4 years with 56% women. Attitudes toward cadaveric donation were favorable in 92% (n = 157). As for living donation, the percentage in favor of nonrelated donation was low: 23% for kidney and 19% for liver. However, when the donation was from a relative, the percentages increased to levels similar to those of cadaveric donation, namely 88% and 85% for kidney and liver, respectively. No differences were observed in attitudes toward cadaveric or living donation according to various psychosocial variables. CONCLUSIONS The trainee doctors showed favorable attitudes toward human cadaveric organ donation as well as living related donation, which suggests a relaunch of living donors in the near future. However, there was not much acceptance of nonrelated donation, as has also been seen in studies of the general public in our geographical area.

Abstract
OBJECTIVE Rural areas present a worse attitude toward organ donation. However, the factors conditioning this attitude are not well known. Our aim was to determine the profile of the population opposed to donation in rural areas. MATERIALS AND METHODS A random sample stratified by age and sex was obtained from municipalities with less than 10,000 inhabitants. Attitudes toward donation were assessed by a questionnaire which evaluated variables that may influence these attitudes. A descriptive statistical study used the Student t test and chi-square test as well as a logistic regression analysis. RESULTS Among 181 respondents, 63% were in favor of donation and 37% against or undecided. Among the reasons to be against donation were rejection of body mutilation (43%) and fear of apparent death (41%). The psychosocial variables against donation were age >or=44 years, primary education or below, no previous experience with donation, no prosocial activities, an unfavorable opinion of the partner, and fear of corpse mutilation. The variables persisting in the multivariate analysis were level of education, previous experience, prosocial activities, and fear of corpse manipulation. CONCLUSIONS Among the rural population the profile of a person opposed to donation was someone older than 44 years, with a low level of education and no previous experience with donation, who does not participate in prosocial activities and is opposed to corpse manipulation.

Abstract
INTRODUCTION The deficiency in livers and waiting list mortality have encouraged more living liver donation, although it is not exempt from morbidity and mortality. The enthusiasm of transplant teams for this kind of donation is increasing; however, the attitudes toward it are not so clear among other health professionals. Our objective was to analyze the attitudes toward living liver donation among hospital professionals in services without habitual relations with transplantation. MATERIALS AND METHODS A random sample was stratified for service not related to transplantation and job category, in a third level hospital with a transplant program. Attitudes toward living liver donation were evaluated using a psychosocial questionnaire on living donation. RESULTS A total of 419 respondents were analyzed (doctors, n = 184; nurses, n = 119; assistant nurses, n = 80; and non-health workers, n = 36), with a mean age of 37 +/- 10 years. The attitude toward living liver donation was favorable in 82% (n = 344). Among the other respondents, half (9%; n = 38) were against and the other half (9%; n = 37) were undecided. No significant differences were found among the doctors, nurses, assistants, and non-health workers. However, when the three categories were grouped in opposition to the non-health workers, there was greater indecision among non-health workers than the others (19% vs 8%; P = .0001). On analyzing the variables that determine this attitude we observed the following: having commented upon and previously discussed donation (P = .016); believing in the possibility of needing an organ oneself (P = .0001); and being in favor of living kidney donation (P = .0001) and cadaveric donation (P = .004). CONCLUSIONS Hospital personnel in services not related to transplantation favor living liver donation, especially if it is a related donation, despite its greater risk, except among non-health workers. However, it is important to conduct informative and awareness-raising campaigns in hospitals if such a type of transplantation is to be encouraged.

Abstract
INTRODUCTION Attitude of health personnel, especially of physicians, has a significant influence on populational attitude towards organ donation and transplantation. The objective here is to analyse the attitude of Primary Care (PC) physicians towards cadaveric organ donation and transplantation and to determine the factors which condition this attitude. MATERIALS AND METHODS A random sample was stratified by geographical location (six health areas of our community) among PC physicians. A total of 155 responses from 32 health centres were collected. Attitude towards donation was evaluated using a psychosocial attitudinal questionnaire about donation validated in our geographical area. The co-ordinator of physicians in each centre was contacted in each centre and was made responsible for distribution and collection of the questionnaires which were completed anonymously. The chi2 test and Student's t-test were applied. RESULTS 88% (n=136) of the PC physicians are in favour of organ donation, 1% (n=2) are against and 11% (n=17) are undecided. Up to 84% of the PC physicians (n=130) have attended to transplant patients, although this fact is not related to a more positive attitude towards donation (p=0.059). In addition, 64% (n=99) have provided favourable information about organ donation and transplantation to their patients and one of the physicians admits having provided unfavourable information about the matter. On analysing the psychosocial variables which influence such an attitude, a relationship has only been found with respect to two variables: attitude towards cadaveric manipulation (p=0.035) and a partner's opinion towards the subject (p=0.006). CONCLUSIONS PC physicians have a very favourable attitude towards donation of their own organs and constitute a positive source of information on the subject for the general public.

Abstract
INTRODUCTION Our hypothesis was that nonhealth workers (NHW) in our hospital should have a more favorable opinion toward xenotransplantation than the general population, given that this group is in closer contact with a preclinical xenotransplantation program. Therefore, our objective was to determine the attitude of NHW in a hospital with a preclinical liver xenotransplantation program and to determine the factors that influenced this attitude. MATERIALS AND METHODS A random sample of 276 subjects in nonhealth services was used. For the distribution of the questionnaire, we contacted the head of each of the services and explained the project. They became responsible for the distribution and collection of the questionnaires in randomly selected work shifts. A random sample of 250 individuals from our community was used as a control group. RESULTS As for animal organ donation for humans, if the results could be superimposed on those achieved by human donors, 63% would be in favor, 30% undecided, and the remaining 7% against. The attitude toward xenotransplantation was more favorable in the control group (74% versus 63%, P < .05). On analyzing the variables that influence attitudes toward xenotransplantation, we found that there is no significant relationship to the classical psychosocial variables (P > .05). However, there is a relationship to prior attitudes toward different types of human organ donation and the possibility of needing a transplant oneself. CONCLUSIONS The attitudes toward xenotransplantation among NHW are not as favorable as in the general population.

Abstract
INTRODUCTION A living donor kidney is currently the most accepted kind of solid organ donation, given the low level of morbidity and mortality and the good results in the recipient. In Spain, its use is still scarce; even many health service workers are not in favor. Our objective was to analyze the attitudes toward living kidney donation in a surgical department. MATERIALS AND METHODS A random sample was stratified according to surgical services and job category in a tertiary hospital with an solid organ transplant program. Attitudes toward living kidney donation were evaluated using a questionnaire on donation and transplantation, which evaluated various psychosocial variables. Student's t test and the Chi square test were used. RESULTS Two hundred sixty-three respondents of mean age 40 +/- 10 years were analysed for attitudes toward living kidney donation. The level of acceptance was 87% (n = 229) versus 13% undecided or against the procedure (n = 34). No differences were observed according to job category. The variables that showed a relationship with the attitude were the partner's attitude toward donation (P = .049); the possible need for an organ oneself (P = .0001); and belief that medical errors occur (P = .001). The attitude toward cadaveric organ donation was not reflective of that toward living kidney donation (P = .241). CONCLUSIONS A favorable attitude toward living kidney donation was high among hospital staff of the surgical department. Those for whom it was not favorable were influenced by personal factors such as partner's attitude and the possibility of needing a kidney in the future.

Abstract
INTRODUCTION There are data that suggest that the percentage of hospital workers not in favor of donation is relatively high, even in services that are directly related to transplantation. The objective was to analyze attitudes toward decreased organ donation in the surgical services. MATERIALS AND METHODS A random sample was stratified by the surgical service and the job category (n = 263) in a third-level hospital with a transplant program assessed attitudes toward the donation of ones own organs after death using a questionnaire including psychosocial factors as validated in our geographic surroundings. Student t test and the chi-square test were used for data analysis. RESULTS Favorable attitudes toward donation were observed in 68% (n = 178) as opposed to 32% with an attitude that was undecided or against the act (n = 85). The psychosocial variables that showed significant relationships with this attitude were age (most in favor are younger; P = .021); nonmedical surgical staff (50% against donation; P = .0001); resident physicians (94% in favor; P = .001); discussion and prior consideration of donation (P = .016); knowledge of the concept of brain death (an important factor in nonhealth staff; P = .010); attitude toward manipulation of the deceased (P = .011) and concerns about mutilation (P = .026); partner's opinion toward organ donation (P = .0001); and existence of frequent medical errors (P = .003). No significant differences were found, depending on whether the services were involved in a specific transplant program (P = .853). CONCLUSIONS Favorable attitudes toward donation among the hospital staff on surgical services, including those who perform transplants, did not reach more than 70% and was determined by multiple psychosocial factors. Donation promotion activities are necessary for these services, given the importance that this group's negative attitude could have on the attitude of the general population.

Abstract
INTRODUCTION Nursing is a fundamental service in caring for the health of the public. The opinion of nurses toward a certain type of donation may have a strong population impact. In this respect, living kidney donation is increasing in Spain; it is important to raise awareness at all levels. The objective here was to analyze the attitudes of primary care nursing personnel toward living kidney donation and to their determinants. MATERIALS AND METHODS A random sample of primary care nurses stratified by geographical location (six health areas in our community), included 139 nurses from 32 health centres. Attitudes toward living donation were evaluated using a questionnaire with various psychosocial variables. For the distribution of the questionnaires, contact was made with the nursing coordinator in each centre. They were completed anonymously. The chi-squared test and Student's t test were applied. RESULTS The attitudes toward living kidney donation were favorable in 93% of those questioned (n = 129), mainly when the donation is related (78%, n = 109). Only one nurse was against the idea of donating a kidney from a living person (1%); nine had doubts about this kind of donation (7%). Seventy-six percent (n = 106) have cared for patients awaiting a transplant; however, no relationship was found with attitude toward this type of donation (P = .209). Of all analyzed variables, there was only a significant relationship with concern about possible body mutilation (P < .0005) and partner's opinion about the matter (P < .0005). We wish to highlight that no relationship was found with attitudes toward cadaveric organ donation (P = .712). CONCLUSIONS Attitudes of primary care nursing personnel toward living kidney donation were favorable, especially if it was related donation.

Abstract
INTRODUCTION Living liver donation is not exempt from risks to the donor, although it is currently ethically accepted. It is important to examine the level of acceptance among the different health levels toward this therapeutic option, in order to design promotion and awareness-raising activities. The objective herein was to analyze the attitudes and the factors that condition them among nursing personnel in Primary Care (PC) toward living liver donation. MATERIALS AND METHODS This random survey was stratified by geographical location (6 health areas in our community) among PC nurses, obtaining a total of 139 nurses from 34 health centers. Attitudes toward living liver donation were evaluated using a questionnaire on donation which included different psychosocial variables. For the distribution of the questionnaire, the nursing coordinator of each centers was contacted to distribute questionnaires which were completed anonymously. The chi-square test and Student t test were applied. RESULTS Attitudes toward living liver donation were favorable in 89% of those questioned (n = 124) if it is related donation; 3% (n = 4) were against donating a living hemiliver and 8% (n = 11) had doubts. It is important that up to 76% (n = 106) have cared for transplant patients or patients awaiting transplant, however, no relationship was observed with attitude to this type of donation (P = .489). Of all the analyzed variables, there was only a significant relationship between attitudes and concern about possible body mutilation (P < .0005), and partners attitudes toward this matter (P < .0005). It is noteworthy that no relationship was found with attitudes toward cadaveric donation (P = .062). CONCLUSION Despite the risk of morbidity and mortality in the donor, the attitude of the PC nursing personnel toward living liver donation was favorable, especially if the donation is related.

Abstract
INTRODUCTION Primary care is an important way of promoting health in the community, and this includes organ donation. In rural areas, this way of promoting health acquires special importance. Our objective was to analyze attitudes toward organ donation among primary care workers in rural health centers to assess their importance in circulating information about donation. MATERIALS AND METHODS A random sample, stratified according to job category among the primary care staff (n = 160), of workers in rural areas in our autonomous community (population < 10,000 inhabitants), evaluated attitudes toward donation using a questionnaire validated in our geographic area. To distribute the questionnaire it was necessary to contact the following in each health center: the coordinating physician, the nursing coordinator, and an administrative worker. RESULTS Of those questioned, 78% (n = 124) were in favor of donation, as opposed to 22% (n = 36) who are against it or undecided. As for the job category, physicians and nurses showed a more favorable attitude than nonhealth workers (90% and 80% vs 61%; P = .000). The psychosocial variables that were related to such an attitude were knowledge of the concept of brain death (P = .013) and lack of fear of manipulation of the deceased person (P = .002). Regarding information about organ donation and transplantation, 54% (n = 86) reported having been provided favorable information, with up to a quarter of the physicians considering other programs to be of greater interest for primary care than organ donation and transplantation. CONCLUSION Attitudes toward organ donation were favorable among a high percentage of primary care workers in rural centers; more than 50% have circulated favorable information on the subject. However, there is a high percentage with a negative or undecided attitude, especially among nonhealth workers, which should be reversed with promotional activities at the level of the health center.

Abstract
The dominant oculo-pharyngeal muscular dystrophy mutation consists of an expanded (GCN)(12-17) in the coding region of the PolyA Binding Protein Nuclear 1 gene. A founder effect has been demonstrated in Canadian and Bukhara Jewish populations with relatively high prevalence of this disease. Since the oculo-pharyngeal muscular dystrophy prevalence was remarkably high in Southern Uruguay, a founder effect was hypothesized. To identify the ancestral haplotype we determined the (GCN) repeat number and the variants of four intragenic SNPs in Uruguayan OPMD families and a control sample. All families carrying the mutation (GCG)(11)(GCA)(3)(GCG) shared a common ancestral haplotype and the age of the mutation was estimated in 37-53 generations by a composite likelihood method. One family carrying the (GCG)(9)(GCA)(3)(GCG) allele had a different haplotype. The genealogical and molecular data suggested that the common ancestors were Canary Islands' settlers that arrived in Uruguay in the XIX century.

Abstract
INTRODUCTION Organ transplantation is a therapy which depends on society for its development. The objectives here are: 1) to understand the structure of public opinion towards organ donation in the population aged over 15 years of age in our Community; 2) to analyse the psychosocial variables which affect this opinion and 3) to define the population profiles on this matter. MATERIALS AND METHODS Random sample (n = 2.000) stratified for age, sex and geographical location (error for 95.5%, e +/- 2.24) to whom we apply a questionnaire about the psychosocial aspects of organ donation. Descriptive statistics, Student's t-test, Chi-squared test and logistical regression analysis. RESULTS 63% have a favourable attitude towards organ donation, of which 11% have a donor's card. A statistical association has been observed between favourable public opinion and different psychosocial variables (p < 0.05), with some independent variables persisting in the multivariate analysis such as age, level of education (OR = 1.78), information given by family members (OR = 1.62), health workers (OR = 2.01) and talks in educational centres (OR = 2.13); previous experience with donation and transplantation (OR = 2.02), knowledge of the concept of brain death (OR = 1.4); partner's favourable opinion towards donation (OR = 2.6), being a blood donor (OR = 3), taking part in prosocial activities (OR = 1.6) and attitude towards incineration of the cadaver after death (OR = 1.8). CONCLUSIONS The profile of a person who is against donation is of a man or woman, > 50 years of age, with primary studies or below, with no previous experience of the matter, who does not understand the concept of brain death nor their partner's opinion towards donation, who has not found out any information about donation through specialised forums, with an unfavourable opinion towards blood donation or pro-social activities and who is fearful of manipulation of the cadaver after death.

Abstract
BACKGROUND Although xenotransplantation is still in an experimental phase, it is presented herein as a possible solution to the organ shortage. However, there are few data concerning how the general public would accept treatment with animal organs, especially after recent incidents of infections of animal origin, such as "avian influenza" or "SARS disease." The aim of this study was to determine the attitude of the general public toward xenotransplantation of organs. MATERIALS AND METHODS Using an opinion survey, a study was performed on a random sample of 250 subjects in an urban setting. The questionnaire was administered by personnel from the regional transplant coordination center. Completion of the form was self-directed and anonymous for each respondent. The attitude toward donation of human and animal organs was evaluated by analyzing different psychosocial variables that may influence this attitude. A descriptive statistical study was performed using Student's t test and the chi-square test. RESULTS Ninety-eight percent of respondents completed the survey (n=245). As for human donation, 60% are in favor of cadaveric donation with 21% are in favor of living donation, a rate that increases to 74% if it is for a living partner. As for animal donation, if the results were similar to those obtained with human organs, 74% (n=181) would accept an animal organ if they needed it, as opposed to 18% (n=45) who were undecided and 8% (n=19) against (P <.005). Analysis of variables that influence attitudes toward xenotransplantation showed that this attitude was more positive among those having had a previous experience with transplantation (P=.028) and those having a positive attitude toward cadaveric donation (P=.007). Factors traditionally related to cadaveric donation, such as manipulation of the body or pro-social activities, showed no influence. CONCLUSIONS In the population studied, a positive attitude toward xenotransplantation was greater than toward cadaveric donation, assuming the results of these two types of transplants were comparable. Such an attitude is related to human donation, although it is not influenced by many traditional factors.

Abstract
OBJECTIVES To determine media through which the population receives information on donation; to analyze the association between the sources of information and the psychosocial variables with respect to the opinion on donation; and to determine how each source of information influences this opinion. MATERIALS AND METHODS A questionnaire on donation was administered to a random sample of 2000 persons stratified by age, gender, and geographical location, of whom 1143 respondents claimed to have no experience with donation and/or transplantation. A statistical analysis was done between the sources of information or the psychosocial variables or their co-variation to determine their specific impact on the population. RESULTS The medium with the greatest impact on the population is television; the second factor is the press and radio; the third is magazines and talks with friends/family; the fourth is hoardings and posters, and campaigns about organ donation; and the last factor is information given by health professionals. In the factor analysis between sources of information and psychosocial variables, an association was observed between press, radio, and information given by health professionals and a higher education level; and between information provided by discussions in schools, by age, and a higher level of education. Sources of Information sources as that have a favorable effect on donation include discussions, (P = .0079), and information by health professionals (P < .0005) and by friends (P = .0132) and by family (P = .0044). CONCLUSIONS Opinion on donation is more favorable among subjects who have received information on an individual basis and at specialized meetings. The only psychosocial variable associated with some sources of information is the level of education.

Abstract
INTRODUCTION The lack of organ donation continues to be a major limiting factor in transplantation. Our aims are: (1) to define the psychosocial profile against organ donation, and (2) to determine the impact of a law on the procurement and transplantation of organs based on "presumed consent" in the population. MATERIALS AND METHODS The population in this study (n = 2000) was randomly selected and stratified according to sex, age, and geographic localization. The attitude toward organ donation and transplantation was evaluated according to a questionnaire that probed psychosocial aspects of donation. Statistical comparisons were performed using the chi2 and logistic regression tests. RESULTS The population attitude toward organ donation was favorable in 63% of subjects, unfavorable in 31%, and 6% did not respond. With regard to the law based on "presumed consent," only 24% of the population agreed with the law; 53% thought it was an abuse of authority. The population subgroup with a negative attitude to the law was characterized by: age over 40 years, low educational level, no previous experience with organ donation or transplant, no experience in prosocial activities, a refusal to accept cadaver manipulation or mutilation, and lack of knowledge of the brain-death concept. CONCLUSIONS The psychosocial profile against donation is a person above 40 years with a low level of education who has never performed prosocial activities, did not have previous experience with organ donation or transplantation, displays no knowledge of the brain-death concept, and rejects cadaver manipulation. For these people a law based on "presumed consent" is considered an abuse of authority.

Abstract
Four strains of Aedes aegypti (L.), one from Cuba and three from Venezuela, were bioassayed for susceptibility to eight insecticides, including the organophosphates, temephos, malathion, fenthion, pirimiphos methyl, and chlorpyrifos, and the pyrethroids, deltamethrin, lambda cyhalothrin and cypermethrin, S, S, S,-tributyl phosphorotrithioate and piperonyl butoxide were used as synergists to assess the involvement of esterases and monooxygenases in organophosphate resistance. Venezuelan strains had low levels of resistance to fenthion and malathion, and moderate to high resistance to temephos, pyrimphos methyl, and chlorpiriphos. All strains were susceptible to the pyrethroids, except the Cuban strain, which had moderate levels of resistance to cypermethrin. Organophosphate resistance in Ae. aegypti is a serious threat to control operations. Integrated strategies for Ae. aegypti control to prevent or delay pyrethroid resistance in Venezuela and Cuba are discussed.

Abstract
The erythropoietic activity (EA) and degree of erythropoiesis attained by patients undergoing hemodialysis (HD) administered recombinant human erythropoietin (rHuEPO) were studied using ferrokinetic measurements and tests of soluble transferrin receptor (sTfR) levels, assessing which parameter is most useful for measurements in clinical practice. Plasma iron 59 ((59)Fe) clearance (half-life [T(1/2)] (59)Fe), plasma iron turnover (PIT), erythron transferrin uptake (ETU), and erythrocyte (59)Fe incorporation were determined in 23 patients before and at 4 months after administration of rHuEPO. sTfR levels, hematopoietic parameters, and iron metabolism parameters were measured periodically. T(1/2) (59)Fe was shortened (P: = 0.004), PIT and ETU were increased (P: = 0.032 and P: = 0.013, respectively), and the time taken by erythrocytes to incorporate 80% of the (59)Fe administered was reduced from 9.6 to 6.1 days. sTfR levels were increased by 15 days; this increase was significant (P: < 0.05) at 30 days, reaching a maximum of 3.22 mg/dL at day 45. A positive correlation was seen between sTfR levels and hemoglobin (Hb) (P: = 0.001), hematocrit (P: = 0.001), and reticulocytes (P: = 0.038) that was not found between ferrokinetic parameters and those evaluating efficient erythropoiesis (P: = 0.345 between ETU and Hb). In conclusion, EA is increased, shown by ETU and sTfR level. sTfR levels correlate with the parameters that evaluate efficient erythropoiesis, and their measurement does not involve the technical and/or ethical limitations of studies of ferrokinetics, making them the tool of choice in clinical practice for the evaluation of EA in patients undergoing HD administered rHuEPO.

Abstract
AIMS The available methods for evaluating proteolysis in meat products, particularly the contribution of micro-organisms, are expensive, time-consuming and require an unacceptable sample size. To minimize these problems, two capillary electrophoresis-based methods have been developed. METHODS AND RESULTS Six Gram-positive, catalase-positive cocci, four moulds and three yeasts, isolated from dry-cured ham, were tested on sterile pork slices. Using the Capillary Gel Electrophoresis (CGE) method, changes in sarcoplasmic and myofibrillar proteins due to endogenous and microbial enzymes were detected. The Capillary Zone Electrophoresis (CZE) analysis allowed evaluation of bulk changes by micro-organisms in soluble nitrogen compounds. CONCLUSION CGE analysis of myofibrillar proteins and CZE determination of soluble nitrogen compounds have proved to be valuable tools for evaluating proteolytic activity of endogenous and microbial origin. SIGNIFICANCE AND IMPACT OF THE STUDY The CGE and CZE methods developed can be used for a rapid and sensitive analysis of proteolysis in meat products.

Abstract
The detection techniques for the activity of non-specific esterases and glutathione-s-transferase in Culex quinquefasciatus were modified to detect such enzymes in Aedes aegypti(L). The optimal concentration values of substrate (saturating concentration) and the optimum reading time for reaction were determined for each enzyme by using 4 Aedes aegypti strains: one from Cuba 2 from Venezuela and one susceptible reference strain. The frequency of non-specific esterases turned out to be 0.76 in MIRANDA 0.42 in ARAGUA and 1 in SANTIAGO DE CUBA in which the highest frequency value of this mechanisms was reached. The frequency of glutathione-s-transferase mechanism was 0.45 in ARAGUA 0.043 in MIRANDA and 1 in SANTIAGO DE CUBA. For the first time in Cuba a set of biochemical techniques was available for detecting the resistance mechanisms of Aedes aegypti which made it possible to create sound foundations for the easy rapid detection of the resistance of this species the main dengue vector in the Americas.

Abstract
Five strains of Aedes aegypti L. one from Cuba and 4 from Venezuela were evaluated to determine their resistance to organophosphate insecticides (temephos, chlorpiriphos and pirimiphos methyl). In the Venezuelan strains only APURE showed resistance to temephos. In TACHIRA and MIRANDA moderate resistance values were noted (FR50 5 to 10x) for chlorpiriphos and high levels of resistance (FR > 10x) to this insecticide were found in ARAGUA. All the Venezuelan strains showed high levels of resistance to pirimiphos methyl. The Cuban strain from Santiago de Cuba revealed moderate resistance to temephos and pirimiphos methyl, but high resistance to chlorpiriphos. The results of the biochemical tests proved the presence of esterase and glutathione-s-transferase at high frequency in almost every strain. By the polyacrilamide gel electrophoresis, a strongly stained band was observed in all the strains with a Rf value of 0.779; it was named esterase A4 and was not seen in the susceptible reference strain. The meaning of this esterase in the resistance to organophosphate insecticides is yet to be determined. Resistance to these insecticides in Aedes aegypti is a serious problem for the control of this species therefore integrated management strategies were proposed to prevent or delay the appearance of this species in Cuba and Venezuela.

Abstract
An arbitrarily primed-polymerase chain reaction (AP-PCR) method was optimized to differentiate Staphylococcus aureus from other staphylococcal species, using DNA from crude cell extract. From the different assays carried out, the best resolution of the band patterns was obtained when the reaction mixture contained 200 micromol l(-1) dNTPs, 200 ng primer, 1 U Taq DNA polymerase and 3 mmol l(-1) MgCl2 and the amplification conditions were: initial denaturation of 94 degrees C for 1 min, primer annealing of 30 degrees C for 1.5 min, DNA extension at 55 degrees C for 5 min and final extension at 55 degrees C for 5 min. The results of the characterization of the staphylococcal isolates by AP-PCR are in accordance with those of the biochemical identification by the API Staph System, time of analysis of the AP-PCR being only 6-7 h. Thus, this technique could be a useful method for microbial quality assurance.

Abstract
The use of malathion to control mosquitoes in Cuba during 7 years until 1986 selected 2 resistance mechanisms: that of elevated activity of nonspecific esterases and that of altered acetylcholinesterase (Ache) in Culex quinquefasciatus (Say). In Havana, specifically in the area under study (Quibú River), malathion was replaced by cypermethrin in 1987 and cycles of treatment with cypermethrin have been intensively used since 1987 up to now when the populations of Aedes or Culex increase. In Culex quinquefasciatus (Say) from the Quibú River the resistance levels, mainly to malathion, declined significantly from 1986 to 1997. An increase of resistance to pyrethroid was observed during that period of 11 years. The mechanism of elevated esterases rose to a frequency of 1 and there was also an increase in the frequency of the mechanism of Ache. The esterase B1, responsible for the resistance to malathion, but not to pyrethroid, was selected in this population until 1986. Starting from the use of pyrethroid for the control in this area, 2 new phenotypes of esterases named A6 and B6, apparently related to pyrethroid resistance, were selected.

Abstract
A study was conducted on the level of resistance to seven insecticides, namely, 3 organophosphate compounds (malathion, chlorpyrifos and pirimiphos-methyl), one carbamate (propoxur) and 1 pyrethroid (cypermethrin, deltamethrin and lambdacialotrine) of three field-collected strains of Blattella germanica (Linnaeus, 1767) from Santiago de Cuba. These strains showed high resistance levels to malathion, cypermethrin, deltamethrin and lambdacialotrine and low resistance to pirimiphos-methyl, and also they were susceptible to chlorpyrifos and propoxur. The levels of resistance to tested organophosphate insecticides such as malathion and pirimiphos-methyl and to pyrethroid compounds like cypermethrin, deltamethrin and lambdacialotrine may be related to the increased production of esterases as a mechanism of resistance. The value of frequency of the resistant genes for enzyme acetylcholinesterase was very low, therefore, the modified acetylcholinesterase is not involved in resistance to insecticides tested in the studied strains from Santiago de Cuba.
