Self-cleaning cellulose acetate/crystalline nanocellulose/polyvinylidene fluoride/Mg0.975Ni0.025SiO3membrane for removal of diclofenac sodium and methylene blue dye in water.

Recalcitrant pollutants present in wastewater, without an effective treatment, have several effects on aquatic ecosystems and human health due to their chemical structure and persistence. Therefore, it is crucial the development of efficient technologies to eliminate such pollutants in water. Nano-photocatalysts are considered a promising technology for water remediation; however, one common drawback is the difficulty of recovering it after water processing. One effective strategy to overcome such problem is its immobilization into substrates such as polymeric membranes. In this study, a polymeric membrane with embedded Mg0.975Ni0.025SiO3is proposed to remove model pollutants diclofenac sodium and methylene blue dye by synergetic adsorption and photocatalytic processes. Mg0.975Ni0.025SiO3was synthesized by the combustion method. The matrix polymeric blend consisting of a blend of cellulose acetate, crystalline nanocellulose and polyvinylidene fluoride was obtained by the phase inversion method. The composite membranes were characterized by FTIR, x-ray diffraction, and scanning electron microscopy. With pollutant solutions at pH 7, the pollutant adsorption capacity of the membranes reached up to 30% and 45% removal efficiencies for diclofenac sodium and methylene blue, respectively. Under simulated solar irradiation photocatalytic removal performances of 70% for diclofenac sodium pH 7, and of 97% for methylene blue dye at pH 13, were reached. The membrane photocatalytic activity allows the membrane to avoid pollutant accumulation on its surface, given a self-cleaning property that allows the reuse of at least three cycles under sunlight simulator irradiation. These results suggest the high potential of photocatalytic membranes using suitable and economical materials such as cellulosic compounds and magnesium silicates for water remediation.

Growth in height and body proportion from birth to adulthood in hereditary hypophosphatemic rickets: a retrospective cohort study.

PURPOSE: Patients with hereditary hypophosphatemic rickets are short and disproportionate and very little information is available on segmental growth, but the body disproportion at adulthood leads us to think that the growth velocity of legs is slower. METHODS: A total of 96 children were included and molecular testing was carried out in 42. Children who reached adult height were classified into two groups according to their compliance to conventional treatment (phosphate supplement and calcitriol). Individual growth records of height and sitting height/height were plotted using Argentine reference data in 96 children and growth curves were estimated by fitting Preece-Baines Model 1 in 19 of the children. RESULTS: Molecular testing revealed sequence deleterious alterations or large deletions in 36/42 patients. During childhood, 76% of children grew below - 1.88 standard deviation score (SDS) and 97% had body disproportion. During adolescence, the mean peak height velocity for the good and poor compliance to treatment groups was 7.8 (0.6) and 5.4 (0.4) cm/year in boys and 7.0 (0.7) and 5.2 (0.8) cm/year in girls, respectively. At adulthood, the median sitting height/height ratio was 2.32 and 6.21 SDS for the good and poor compliance to treatment groups, respectively. The mean pubertal growth spurt of the trunk was -0.8 (1.4) SDS, with a short pubertal growth spurt of - 1.8 (0.4) SDS for limbs in the good compliance group. Median adult height in 13/29 males and 30/67 females was -4.56 and -3.16 SDS, respectively. CONCLUSION: For all patients the growth spurt was slower, secondary to a short growth spurt of limbs, reaching a short adult height with body disproportion that was more prominent in the poor compliance group.

Comprehensive diagnosis of parasites in sheep kept under different zootechnical management in a region temperate in Mexico.

Parasites cause losses in animal production. Parasite infection in ruminants has been estimated to be a major problem causing more than 3 billion USD per year, from which 60% corresponds to the sheep industry. Treatment is based on the use of synthetic anthelmintics; however, repeated application or under dosage have resulted in the selection of nematodes resistant to anthelmintics. The objective of the present work was to perform a diagnosis of gastrointestinal parasites in sheep kept under different zootechnical management. Ninety female sheep were used, most of them pregnant. Sampling was performed monthly from December 2015 to June 2016 (flock 5 until April). Fecal samples were collected from the rectum; the McMaster technique was performed, morphological characteristics were observed, oocysts and eggs were counted per gram of feces (opg and epg), frequency and intensity were obtained. Faecal culture was performed for feces that had a positive result, infective larvae were obtained and taxonomically identified. At the end of the study, a dewormer (fenbendazole) was administered and its effect was measured. The frequency of gastrointestinal parasites was 100%. The highest opg was 3,600 (flock 3, March, 2016), the epg for cestodes was 2800 (flock 1, January, 2016) and for gastrointestinal nematodes (GIN) was 25,000 (flock 1, May, 2016); the intensity was variable and it was increased by peripartum. Protists (Eimeria spp), cestodes (Moniezia) and nematodes (Haemonchus, Trichostrongylus, Cooperia, Chabertia ovina. Teladorsagia, Oesophagostomum, Nematodirus and Trichuris ovis) were identified. No previous diagnosis is performed in flocks, and sometimes dewormers are administered, even though resistance to ivermectin and benzimidazole is suspected. Flock management, its feeding system and its conditions were determinant for the observed results; therefore, it is necessary to count with a diagnosis that provides information about the parasitic population and its dynamic, in order to carry out a selective and comprehensive control that has an impact on the animal, human and environmental health.

Predictores de dolor anterior de rodilla en pacientes operados de artroplastia total de rodilla sin reemplazo patelar / Predictors of anterior knee pain in patients operated of arthroplasty total knee without patellar replacement

Osteoarthrosis of the knee is one of the most important causes of disability around the world, being total knee arthroplasty (TKA) a cost-effective surgical procedure for treating its severe stage when all knee compartments are compromised. Despite the good functional results and good survival of the implants and of the patients, still, 15 to 20% of the patients are dissatisfied after surgery. One of the causes of dissatisfaction is persistent pain located in the anterior part of the knee, which leads to controversy over whether to perform the patellar replacement. Advantages and complications are described in both scenarios, and neither is superior to the other in pain and implant survival. In the case of TKA without patellar replacement, the position of the femoral component plays a crucial role in achieving normal patellar tracking. The current challenge is to determine those clinical and radiological variables that allow us to predict the absence of long-term anterior pain in patients who require TKA and who do not undergo patellar replacement.

Factors Related to the Attitude Toward Living Kidney Donation of the Population of Havana.

INTRODUCTION: Living kidney donation (LKD) is one of the most used alternatives in the field of organ transplantation. OBJECTIVE: Analyze the attitude toward LKD among the population of Havana, Cuba. METHODS: Population under study. Population resident in Havana, Cuba. INCLUSION CRITERIA: Sample of population over 15 years stratified by age and sex. INSTRUMENT: Validated questionnaire of attitude toward donation and transplant "PCID-DVR-Ríos," self-administered and anonymously filled out. STATISTICS: χ2, Student t test, and a logistic regression analysis. RESULTS: A total of 920 respondents have been included in the study. A total of 85.5% (n = 787) are in favor of the related LKD. In our study, 26.5% (n = 244) would remain in favor of unrelated LKD. Regarding the related LKD, the following variables remain independent in the multivariate analysis: 1. having studies (odds ratio [OR] = 3.649; P = .018); 2. attitude toward cadaveric organ donation (OR = 8.547; P < .001); 3. religion (OR = 4.385; P = .001); 4. opinion of the couple (OR = 4.672; P = .028); and 5. risk with living donation (OR = 10.989; P = .003). CONCLUSIONS: The population of Havana has a very favorable attitude toward related LKD. Only a quarter of respondents are in favor of unrelated LKD.

Oncologic impact of micrometastases or isolated tumor cells in sentinel lymph nodes of patients with endometrial cancer: a meta-analysis.

PURPOSE: There is a gap in knowledge regarding the impact of micrometastases (MIC) and isolated tumor cells (ITCs) found in the sentinel lymph nodes of patients with endometrial cancer. Here, we present a meta-analysis of the published literature on the rate of MIC and ITCs after lymphatic mapping and determine trends in postoperative management. METHODS: Literature search of Medline and PubMed was done using the terms: micrometastases, isolated tumor cells, endometrial cancer, and sentinel lymph node. Inclusion criteria were: English-language manuscripts, retrospectives, or prospective studies published between January 1999 and June 2019. We removed manuscripts on sentinel node mapping that did not specify information on micrometastases or isolated tumor cells, non-English-language articles, no data about oncologic outcomes, and articles limited to ten cases or less. RESULTS: A total of 45 manuscripts were reviewed, and 8 studies met inclusion criteria. We found that the total number of patients with MIC/ITCs was 286 (187 and 99, respectively). The 72% of patients detected with MIC/ITCs in sentinel nodes received adjuvant therapies. The MIC/ITCs group has a higher relative risk of recurrence of 1.34 (1.07, 1.67) than the negative group, even if the adjuvant therapy was given. CONCLUSION: We noted that there is an increased relative risk of recurrence in patients with low-volume metastases, even after receiving adjuvant therapy. Whether adjuvant therapy is indicated remains a topic of debate because there are other uterine factors implicated in the prognosis. Multi-institutional tumor registries may help shed light on this important question.

Risk factors associated with congenital defects that alter hearing or vision in children born in the city of Bogotá between 2002 and 2016.

INTRODUCTION: Congenital defects affecting the auditory and visual capacity of newborns represent a public health problem as they result in substantial disability, directly impacting the quality of life of newborns and their families. OBJECTIVE: To evaluate risk factors associated with congenital defects that alter hearing or vision in newborns in the city of Bogotá between 2002 and 2016. METHOD: Data from the Bogotá Birth Defects Surveillance and Follow-up Program was used, which consolidated data regarding 167 ECLAMC study (Estudio Colaborativo Latino Americano de Malformaciones Congénitas, in spanish) variables in a case-control design to identify risk factors for birth defects after parents provided signed informed consent. Cases were defined as any newborn (alive or stillborn) with a weight greater than 500 g with any visual or hearing abnormality. Controls were defined as newborn in the same hospital and month with no birth defects. Groups were formed according to the case presentation as follows: isolated eye anomaly, isolated ear anomaly, polymalformative, syndromic, and teratogenic. RESULTS: In total, 402,657 births were reviewed, of which 968 cases had some congenital defects that alter hearing or vision. An association was found between the presence of defects and prematurity, as well as between syndromic cases and increasing maternal age. When comparing cases and controls with the risk of having a birth defect, multiparity had an odds ratio (OR) of 1.47 (95% CI: 1.27-1.71), acute respiratory infection had an OR of 2.41 (95% CI: 1.04-5.58), low maternal education level had an OR of 1.34 (95% CI:1.10-1.62), low paternal education had an OR of 1.42, (95% CI:1.17-1.73), manual labor in the maternal occupation had an OR of 1.31 (95% CI:1.03-1.67), and a history of congenital anomalies in the family had an OR of 1.55 (95% CI:1.19-2.00). CONCLUSION: This research allowed the identification of epidemiological data and significant risk factors for congenital defects that alter hearing or vision in the population of Bogotá.

Knowledge of the Brain Death Concept in Dominican Immigration Residents in Spain and Florida.

The Latin American population has a double way of immigration, one toward the United States by proximity and another toward Spain by sociocultural affinity. This population increase is affecting organ donation and transplantation in receiving countries. OBJECTIVE: To analyze the brain death (BD) concept knowledge in the Dominican Republic immigrant population in Florida (United States) and Spain. METHOD: Population under study: Population born in the Dominican Republic, resident in Florida (United States) and in Spain. INCLUSION CRITERIA: Population older than 15 years stratified by age and sex. Assessment instrument: Donation attitude questionnaire PCID-DTO-Ríos. Fieldwork: Random selection based on stratification. Immigration support association collaboration in Florida and Spain was needed to locate potential respondents. Completion was anonymous and self-administered, with verbal consent. RESULTS: A total of 123 respondents, 57 residents in Spain and 66 in Florida, have been included in the study. The 27% (n = 33) of the respondents knowledgeable of the BD concept consider it the death of an individual. Of the remainder, 52% (n = 64) do not know about it, and the remaining 21% (n = 26) believe it does not mean the death of a patient. No differences were observed regarding migration countries (P > .05). There was no association of the BD concept with other psychosocial factors analyzed or with the attitude toward organ donation. CONCLUSIONS: Knowledge of the BD concept among the Dominican immigrant population is similar in Spain and Florida, and, unlike most studies, there is no objective association with the attitude toward organ donation.

Multivariate Analysis of Factors Affecting Attitude Toward Living Kidney Donation Among the Puerto Rican Population Resident in Florida.

Puerto Rican and Cuban populations are 2 of the most important migration groups in Florida. Awareness about organ donation among them is fundamental. It is important to determine the factors that influence attitudes toward organ donation. OBJECTIVE: To analyze the attitude toward living kidney donation (LKD) among Florida's Puerto Rican residents. METHODS: Study population: Population born in Puerto Rico resident in Florida (United States). INCLUSION CRITERIA: A sample of population older than 15 years was obtained randomly and stratified by age and sex. Instrument valuation: LKD attitude questionnaire Proyecto Colaborativo Internacional Donantesobre Donación de Vivo Renal, Rios. SETTING: for the study: Random selection based on stratification. Immigration support associations in Florida were needed to locate potential respondents. Anonymized and self-administered with verbal consent completion. RESULTS: Of the 259 respondents, 55% (n = 143) are in favor of related LKD (family or friends). The following factors were associated with this attitude: marital status (P = .008); educational level (P < .001); personal experience with organ donation and transplantation (P < .001); attitude toward deceased organ donation (P < .001); realization of prosocial activities (P = .02); family comments about organ donation (P < .001) and comments within couples (P < .001); not being concerned about possible mutilation of the body after donation (P < .001); believing that one's own religion was in favor of donation and transplantation (P < .001); economic incentives of donation (P < .001), and evaluation of the risk from living kidney donation (P < .001). In the multivariate analysis, only marital status is featured as an independent variable (odds ratio, 32.258; P < .001). CONCLUSIONS: The attitude toward related LKD among the Puerto Rican population who resides in Florida is not very favorable; only 55% would do it.

Attitude Toward Organ Donation in the Population of Cienfuegos, Cuba.

INTRODUCTION: The sensitization of the population toward organ donation is fundamental; for that reason, it is important to determine the factors that condition the opinion toward donation on the population scope in order to carry out cost-effective campaigns. OBJECTIVE: To analyze the attitude toward the donation of the proper organs for transplantation among the population residing in Cienfuegos, Cuba. METHOD: Population under study: Population who reside in Cienfuegos, Cuba. INCLUSION CRITERIA: Population over 15 years old as stratified by age and sex. Assessment instrument: The attitude questionnaire for organ donation for transplant-PCID-DTO Ríos. Fieldwork: A random selection based on stratification. The available data from the census were used. The completion was anonymous and self-administered. Verbal consent was requested to collaborate in the study. STATISTICS: Student t test, χ2, Fisher, and a logistic regression analysis. RESULTS: A sample of 636 respondents was included in the study, of which 71% (n = 453) are in favor of donating their organs after death, 16% (n = 103) are against, and 13% (n = 80) are undecided. This attitude is associated with different psychosocial variables (P < .001): age, marital status, having offspring, level of studies, carrying out prosocial activities, discussing with the family the subject of donation and transplantation, knowledge of the concept of brain death, the attitude toward the manipulation of the corpse, the religion of the respondent, and the attitude of the couple toward organ transplantation. The main independent factors obtained in the multivariate analysis (odds ratio >2.5): knowledge of the brain death concept, attitude toward the manipulation of the corpse, religion, and attitude of the couple toward transplantation. CONCLUSIONS: The attitude toward organ donation among the population of Cienfuegos, Cuba, is favorable and is conditioned by several psychosocial factors.

There Is Great Ignorance About the Brain Death Concept Among the Population in Santiago de Cuba (Cuba).

INTRODUCTION: The knowledge of the brain death (BD) concept is important when determining the attitude toward organ donation. OBJECTIVE: To analyze the level of knowledge of the BD concept among the population in Santiago de Cuba and determine the factors that condition it. METHODS: From the Collaborative International Donor Project, we obtained a sample of Cubans living in the area of Santiago de Cuba (n = 455). The attitude was assessed using a validated questionnaire (PCID-DTO-RIOS). The survey was self-administered and completed anonymously. Student t test, χ2, Fisher, and logistic regression analysis were used. RESULTS: Forty percent (n = 180) of the respondents know the BD concept and consider it as the death of an individual. Of the rest, 43% (n = 199) do not know about it, and the remaining 17% (n = 76) consider that it does not mean the death of a patient. The variables significantly related to the correct knowledge of BD in the multivariate analysis and considered as independent are: level of studies; the opinion of the couple toward organ donation; the religion of the respondent; having offspring; and a favorable attitude toward organ donation. CONCLUSION: There is ignorance about the brain death concept among the population of Santiago de Cuba. This lack of knowledge has a direct relationship with various psychosocial factors.

Multivariate Analysis of the Factors Affecting Attitude Toward Organ Donation Among the Ecuadorian Population Residing in Spain.

INTRODUCTION: Immigrants from Ecuador represent the largest group of Latin Americans in Spain and are, therefore, a subgroup of interest to understand their attitudes and influences in respect to organ donation and transplantation. OBJECTIVE: To analyze the attitude of nationals of Ecuador residing in Spain regarding deceased organ donation. METHODS: The study population included the Ecuadorian population residing in Spain. A sample of population older than 15 years was obtained randomly and stratified by age and sex (n=461). Attitude was assessed using a validated questionnaire on psychosocial aspects toward organ donation (PCID-DTO-Ríos). Assistance from immigration support associations in Spain was needed to advice on the location of potential respondents. RESULTS: Attitude toward cadaveric donation was favorable in 59% (n=271) of respondents, 12% (n=57) were against cadaveric donation, and 29% (n=133) were undecided. Several variables were associated with having a more favorable attitude. In the multivariate analysis, the following variables were independently associated with a more positive attitude toward organ donation: 1. level of formal education (odds ratio [OR]=6.849 [25.641-1.818]; P = .004); 2. being in favor of donating a family member's organs (OR=8.849 [20.833-3.717]; P < .001); 3. having commented at a family level about transplant (OR=3.717 [6.578-2.109]; P < .001); 4. not being concerned about the possible mutilation of the body after donation (OR=4.608 [8.547-2.487]; P < .001) and 5. knowing the attitude of one's religion toward donation (OR=7.462 [34.482-1.623]; P = .010). CONCLUSIONS: The attitude toward cadaveric organ donation among the Ecuadorian population residing in Spain is less favorable than that of the Spanish population and is determined by many different psychosocial variables.

Knowledge of the Concept of Brain Death: Is This an Obstacle in the Acceptance of Donation and Transplantation of Organs Among the Bolivian Population Residing in Spain?

INTRODUCTION: The Bolivian population is growing in Spain. The knowledge and acceptance of the concept of brain death are fundamental. OBJECTIVE: To analyze the level of understanding of the brain death concept among the population of Bolivians residing in Spain. METHODS: The study population was Bolivians living in Spain. The inclusion criteria were being older than 15 years, being born in Bolivia, and residing in Spain; participants were selected randomly from this group and stratified by age and sex. Knowledge of the concept of brain death was assessed using a validated questionnaire on psychosocial aspects toward organ donation. A group of people to be surveyed was randomly selected. Assistance from immigration support associations in Spain was needed to advise on the location of potential respondents. The survey was self-administered and completed anonymously. RESULTS: Of the 206 respondents, 27% understood brain death (BD) and believed that this was the death of an individual. Of the rest, 18% did not understand it and the remaining 55% believed it did not mean the death of a patient. Those who understood the concept of BD were more in favor of deceased donation than those who did not (52% vs 47%; P = .886). None of the sociopersonal variables analyzed is associated with knowledge of the concept of BD. A high percentage of respondents indicated fear of apparent death during organ donation. CONCLUSIONS: The majority of the Bolivian population residing in Spain does not understand the concept of BD. Contrary to most psychosocial studies, it is not associated with attitudes toward organ donation or other sociopersonal factors.

Attitude of the Citizens of Havana, Cuba, Toward Organ Donation: A Multivariate Analysis of the Psychosocial Factors Affecting Attitude.

INTRODUCTION: Because personal decisions affect the availability of organs for transplants, awareness about organ donations among the general population is fundamental. OBJECTIVE: To analyze attitudes toward organ donation among the citizens of Havana, Cuba. METHODS: The sample population was the residents of the city of Havana, Cuba. The inclusion criterion was being older than 15 years; the sample was obtained randomly and stratified by age and sex. Attitude was assessed using a validated questionnaire on psychosocial aspects of organ donation and transplant (PCID-DTO-Ríos). A random selection of people to be surveyed was carried out. RESULTS: A sample of 920 respondents was included in the study. Attitude toward cadaveric donation was favorable in 68% of respondents, while 14% were against and 18% were undecided. Several variables were associated with having a more favorable attitude. In the multivariate analysis, the following variables continue to feature as independent variables (P < .05): 1. level of studies; 2. knowledge of the concept of brain death; 3. attitude toward organ donation of a relative; 4. having discussed the issue of organ donation and transplantation with one's family; 5. the attitude of the couple toward organ donation and transplantation; 6. the religion of the respondent; 7. knowing the opinion of one's religion toward organ transplantation; 8. fear of manipulation of the body after death; and 9. acceptance of burial as a treatment of the body after the death. CONCLUSIONS: The attitude toward cadaveric organ donation among the residents of Havana is favorable and similar to that of the citizens of Spain. Improving the organ procurement system will increase donation rates given the population's awareness of the issue.

CONCLUSIONS: The attitude toward cadaveric organ donation among the Santiago, Cuba population is favorable and it is associated with several psychosocial factors.

Are Dominicans in Favor of Xenotransplantation? A Study of the Attitude of Dominican Immigrants Residing in Spain and the United States.

Xenotransplantation carries many social and cultural implications. The immigrant population in countries with xenotransplantation programs, such as Spain and the United States, will play an important role in accepting such therapy. The objective of the study is to analyze the attitude toward xenotransplantation among the Dominican population residing in the United States and Spain. METHODS: The study population was born in the Dominican Republic and resides in the southeastern United States and Spain. A sample population older than 15 years was obtained randomly and stratified by age and sex. Attitude was assessed using a validated questionnaire on psychosocial aspects toward xenotransplantation (PCID-XENOTx-Ríos). A random selection of people to be surveyed was carried out. Assistance from immigration support associations was needed to advise on the location of potential respondents. RESULTS: A total of 123 respondents were included in the study: A sample was taken of residents of the population from the Dominican Republic residing in Florida, United States (n = 66), and in Spain (n = 57). If it was assumed that xenotransplanted organs functioned as well as human ones, 30% would be in favor. If the results were worse, only 7% would be in favor. This favorable attitude was related to the following variables (P < .05): level of education, an attitude in favor of deceased and living organ donation, and having spoken about donation and transplantation within the family. CONCLUSIONS: The attitude toward xenotransplantation among the population from the Dominican Republic who are residing in the southeastern United States and Spain is unfavorable.

Level of Acceptance of Solid Organ and Tissue Xenotransplantation Among the Bolivian Population Residing in Spain.

The Bolivian population is growing in Spain. Xenotransplantation of organs and/or tissues carries many social and cultural implications. It is important to find out the level of acceptance of xenotransplantation in immigrant populations, especially in populations where there are preclinical trials. The objective of the study is to analyze the attitude toward xenotransplantation of organs and tissues in the Bolivian population residing in Spain and the variables that influence their attitude. METHODS: We selected a sample of the Bolivian population living in Spain. A sample of the population older than 15 years was obtained randomly and stratified by age and sex. Attitude was assessed using a validated questionnaire on psychosocial aspects toward xenotransplantation (PCID-XENOTX-Ríos). RESULTS: Of the 206 respondents, 26% of respondents are in favor of xenotransplantation of organs if it was assumed that xenotransplanted organs functioned as well as human ones. If the results were worse, only 6% would be in favor. The following factors were associated with this attitude: (1) level of education (P = .008), (2) a favorable attitude toward human donation (P = .004), (3) a partner's favorable attitude toward transplantation (P < .001), and (4) a belief that one might need a transplant in the future (P = .01). The following were associated with attitude in the multivariate analysis: (1) having secondary education (odds ratio, 3.690; P = .004) and (2) a partner's favorable attitude toward transplantation (odds ratio, 6.024; P = .003). CONCLUSIONS: The attitude of Bolivian residents in Spain toward xenotransplantation is negative and is determined by educational and family factors.

Emigration From Puerto Rico to Florida: Multivariate Analysis of Factors That Condition Attitudes of the Puerto Rican Population Toward Organ Donation for Transplant.

BACKGROUND: The Puerto Rican population represents one of the largest immigration groups in Florida, and this has an impact on the organ transplant donation process. Our aim was to analyze attitudes toward organ donation among Puerto Ricans who currently reside in the state of Florida (USA). METHODS: The population screened consisted of individuals >15 years old, who were born in Puerto Rico, living in Florida, and awaiting organs for transplant. All participants completed the "PCID-DTO Rios" questionnaire. Random selection was done according to stratification. Support from immigration associations in Spain was needed for advice on the locations of potential respondents. Study participation was anonymized and self-administered. RESULTS: There were 259 respondents, 37% (n = 95) were in favor of donation, 36% (n = 93) were against donation, and 27% (n = 71) were undecided. The variables associated with these attitudes were: age (P = .017); civil status (P = .021); level of education (P < .001); previous experience with donation and transplant (P < .001); attitude toward organ donation of a relative (P < .001); carrying out pro-social activities (P < .001); discussing the issue of transplant with the family (P < .001) or couple (P < .001); attitude toward incineration (P < .001), burial (P < .001), and autopsy (P < .001); fear of mutilation after donation (P < .001); and religious beliefs (P < .001). In the multivariate study, it remained an independent variable to have discussed the issue at the family level (odds ratio = 11.627; P = .009). CONCLUSION: The Puerto Rican study population residing in Florida has an unfavorable attitude toward organ donation.

Differences in Attitudes Toward Living Kidney Donation Among Dominican Immigrants Living in Spain and the United States.

BACKGROUND: The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. METHODS: All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Ríos") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. RESULTS: The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P < .001), previous experience with organ donation (P = .006), attitude toward cadaveric organ donation (P < .001), belief in the possibility of needing a transplant in the future (P = .016), discussing the issue with one's family (P = .007), discussing the issue with husband/wife/partner (P = .002), carrying out pro-social activities (P = .029), religious beliefs (P = .001), and understanding the risk of living kidney donation (P = .046).

Factors That Affect the Attitudes of the Bolivian Population in Spain With Regard to Organ Donation for Transplant.

BACKGROUND: The Bolivian population is an emerging Latin American immigrant group in Spain, several of whom have been transplanted or are awaiting transplant. We aimed to assess attitudes toward organ donation among Bolivians currently residing in Spain. METHOD: The population screened was born in Bolivia but living in Spain, stratified by gender and age. The appraisal tool used was a questionnaire that assesses attitudes toward organ donation for transplant ("PCID-DTO Ríos"). Support from immigration associations in Spain was needed for advice on locations of potential respondents. Survey participation was anonymized and the questionnaire was self-administered. Verbal consent was obtained before participation. RESULTS: There were 206 respondents: 49% (n = 101) in favor of donating their organs after death; 21% (n = 44) against donation; and 30% (n = 61) undecided. Their attitudes were found to be associated with level of education (P = .008), previous experience with donation and transplant (P = .011), concern regarding mutilation after donation (P = .002), knowing the attitude of their religion toward transplant (P = .001), the opinion of their partner (P < .001), and the possibility of needing a future transplant (P = .050). In the multivariate study, the main factor was having a partner in favor of organ donation (odds ratio = 16.129; P = .003). CONCLUSION: Attitudes toward organ donation among Bolivians residing in Spain are far more negative compared with rest of the Spanish population, due to various factors.
