RESUMO

BACKGROUND: The Cuban population residing in the state of Florida in the United States forms the largest population group of immigrants in that state. It has been described as a population with little awareness of organ donation. The objective is to analyze the factors that Cubans residing in the Florida refer to when expressing an unfavorable attitude toward organ donation and to determine the psychosocial factors associated with the attitude toward organ donation of this population group. METHODS: We performed a cross-sectional observational study. From the Proyecto Colaborativo Internacional Donante (International Donor Collaborative Project), a sample stratified by age and sex of Cubans residing in Florida (N = 1224) is obtained. The sample is analyzed using the validated questionnaire (PCID-DTO-RIOS). The reasons against organ donation were analyzed using a specific multiresponse item, with an open response option. For the analysis of the psychosocial variables, a logistic regression analysis is carried out. RESULTS: A total of 38.2% (n = 468) of the individuals under study declared themselves against organ donation. Of those who were against, the reasons stated were (1) leave the dead in peace (n = 440; 57.6%); (2) religious reasons (n = 192; 25.1%); (3) fear of mutilation (n = 160; 20.9%); (4) assertive refusal (n = 128; 16.8%); (5) apparent death (n = 16; 2.1%); and (6) other reasons (n = 764; 62.4%). CONCLUSIONS: The Cuban population residing in Florida who is against organ donation expresses various reasons. In addition, there are factors associated with the psychosocial profile toward organ donation of this important population group.

RESUMO

Cuban immigrants constitute an important group in both the United States and Spain, with different behaviors toward organ donation having been described among the different Latin American nationalities. We analyzed the attitude toward organ donation among the Cuban populations in Cuba, Spain, and Florida. The study population was Cuban immigrants over 15 years of age residing in Cuba, Spain, and Florida, with samples randomly stratified by age and sex. A validated questionnaire on psychosocial aspects of organ donation (PCID-DTO Rios) was used. Census was used as the sampling base in all 3 countries; however, additionally, in Spain and the United States (Florida), we sought the support of immigration support associations to determine the Cuban population without legal documentation. The questionnaire was completed anonymously and self-administered. The completion rate of the study was 74% (4123/5574) among 424 surveyed in Spain, 1224 in Florida, and 2475 in Cuba. The attitude in favor of donating their own organs upon death was 60.6% of those surveyed in Spain, 37.6% in Florida, and 68.9% in Cuba, or 58% of the global sample. Multivariate analysis showed that country of residence was an independent factor associated with attitude toward organ donation (odds ratio, 1.929). Other factors associated with attitude were sex, educational level, performance of prosocial activities, knowledge of the brain death concept, religion, the couple's opinion toward donation, fear of mutilation after donation, and attitude toward manipulation of the body after death. The attitude toward organ donation among Cubans in their country of origin and immigrants in Spain was similar, being significantly different from those who emigrate to Florida, where the attitude is much less favorable.

RESUMO

RESUMO Objetivo O objetivo principal do presente estudo foi examinar a contribuição da nomeação automatizada rápida (NAR) para velocidade e compreensão de leitura. Analisou-se, também, se o desempenho da tarefa de nomeação automatizada rápida em ano inicial da escolaridade poderia ser preditora da habilidade ulterior em velocidade e compreensão de leitura textual. Métodos Foram analisados 40 protocolos das avaliações das habilidades do processamento fonológico, sendo elas: nomeação automatizada rápida, consciência fonológica e memória de trabalho fonológica, assim como avaliação da velocidade e compreensão de leitura, realizadas em 2008 e 2011, quando as crianças cursavam, respectivamente, o 2º e o 5º ano do ensino fundamental I. Resultados No 2º ano, a NAR de objetos foi capaz de prever o desempenho em velocidade de leitura. Já no 5º ano, a NAR de letras assumiu tal papel. No 2º ano, a NAR contribuiu de forma indireta, por meio da velocidade de leitura, para o desempenho das crianças em compreensão leitora. Já no 5º ano, dentre as habilidades do processamento fonológico, a memória de trabalho se destacou por se correlacionar significativamente com a compreensão da leitura. A velocidade de leitura do 2º ano previu o desempenho da velocidade de leitura no 5º ano. Conclusão Os achados deste estudo se mostram importantes para a prática clínica e educacional, reforçando que a NAR apresenta importante contribuição para a velocidade de leitura e esta, por sua vez, é importante para a compreensão de leitura.

ABSTRACT Purpose The main objective of the present study was to examine the contribution of rapid automatized naming (RAN) to reading rate and text comprehension. We also analyzed whether the performance on a rapid automatized naming task in the first year of schooling could be a predictor of the future skill in reading speed and text comprehension. Methods Forty protocols with phonological processing skills assessments were analyzed, namely: rapid automatized naming, phonological awareness and phonological working memory, as well as assessment of reading rate and comprehension, carried out in 2008 and 2011, when children were respectively, in the 2nd and 5th grades of Elementary School I. Results For children in 2nd grade, the RAN of objects was able to predict their performance in reading speed, whereas for children in 5th grade, the performance of RAN of letters plays such a role. In the 2nd grade, RAN contributes indirectly, through reading speed, to the performance of children in reading comprehension. In the 5th grade, among the phonological processing skills, working memory stands out for correlating significantly with reading comprehension. The reading speed of the 2nd grade was able to predict the performance of the reading speed in the 5th. grade. Conclusion Such findings are important for clinical and educational practice, reinforcing that RAN is an important skill which contributes to reading rate which in turn, is important for reading comprehension

RESUMO

Cultural tightness-looseness represents the degree to which a particular culture possesses strong behavioral norms, and the degree to which members of that culture are likely to sanction individuals who deviate from those norms. While tightness-looseness has been quantified for a large and growing number of countries around the world, there are many countries where a tightness-looseness score has yet to be determined, thus impeding the inclusion of those countries in cross-cultural research with a tightness-looseness focus. There is a dearth of research on cultural tightness-looseness in South America in particular. We report results from a national survey of 1,265 Ecuadorian residents which provided quantification of the relatively tight culture of Ecuador.

RESUMO

BACKGROUND: Cuba is one of the Latin American countries with the highest rates of organ donation. Social and cultural differences among the population throughout the country may also affect attitudes toward donation. Knowledge of these characteristics would facilitate awareness of the population most reluctant to donate and transplant. OBJECTIVE: We sought to analyze the differences in attitudes toward organ donation among Cubans living in the main capitals of Cuba. MATERIALS AND METHODS: Study population. The study group was the Cuban population living in the cities of Cienfuegos (n=636), Havana (n=920), and Santiago de Cuba (n=455), extracted from the database of the International Collaborative Donor Project. Sample of the population. Participants were older than 15 years, and data were stratified by geographic area, age, and sex. Assessment instrument. We used a validated questionnaire of attitude toward organ donation for transplant (PCID-DTO-Ríos), anonymously filled in and self-administered. STATISTICS: Student t test was applied together with the χ2 test, complemented by an analysis of the remainders. RESULTS: The favorable attitude among inhabitants in Cienfuegos was 71.2% (n=453), 68.3% (n=628) among those in Havana, and 69.5% (n=316) among those in Santiago de Cuba (P < .05). The psycho-social profile of respondents favoring organ donation was similar in the 3 cities. CONCLUSIONS: The attitude toward organ donation among the population of the main cities of Cuba was favorable and similar in all of them. The psycho-social profile toward organ donation was similar in the 3 cities.

RESUMO

The aim of this study was to investigate (1) whether a sample of highly educated individuals with dyslexia living under optimal personal, educational, cultural, and socioeconomic conditions continues to display core deficits in reading and writing skills during adulthood (extending prior results in Dutch, English, Hebrew, and Spanish to the Portuguese writing system); (2) whether these individuals can compensate for the effects of persistent core deficits when reading complex academic texts; (3) which cognitive resources, such as reading strategies, are used as compensatory mechanisms; and (4) whether quality of life is affected in these individuals. These questions were examined in a sample of 28 adults with dyslexia (DG) and 28 control participants (CG) paired by sex, age, education, and occupation, with a mean of 15 years of formal education. Participants completed measures of phonological awareness; decoding of syllables, words, and pseudowords; writing; reading comprehension (inferential and literal questions, recall, and sensitivity to the rhetorical structure of the target text); and quality of life. Results showed that (1) core deficits associated with dyslexia persisted into adulthood: participants with dyslexia performed worse than control subjects at all levels of phonological awareness, reading (except word reading accuracy), and spelling; (2) the groups did not differ on any measures of reading comprehension, suggesting a compensation of core deficits; (3) three compensatory mechanisms were identified: slower reading, use of text structure, and verbal ability; (4) participants with dyslexia required more family support and professional help throughout their educational careers, and had more depressive symptoms than control subjects.

RESUMO

BACKGROUND: The Ecuadorian population forms the largest Latin American immigrant group in Spain. However, their knowledge about the brain death (BD) concept and the relationship with the attitude toward organ donation has been little analyzed. The objective of the study is to analyze the knowledge of the BD concept among the Ecuadorian population resident in Spain. METHODS: The population under study was the population born in Ecuador and resident in Spain. Inclusion criterion was age older than 15 years stratified by age and sex. The assessment instrument was PCID-DTO-Ríos, a validated questionnaire of attitude toward donation and organ transplantation. Field work involved random selection of respondents based on stratification. The support of immigration support associations was required to obtain sample locations. The completion was anonymous and self-administered. RESULTS: Of the 461 respondents, 22% (n =102) know the BD concept and accept it as the death of the person; 61% (n = 283) do not know it; and for 17% (n = 76) it does not mean the death of the person. The variables related to the correct knowledge of BD are age (P = .007) and marital status (P = .028), with age persisting in the multivariate study (odds ratio, 1.036; P = .008). There is no objective relationship with the attitude toward organ donation. Thus, 60% of those who know the concept are in favor of donating (n = 61), and 59% of those who do not know it are in favor (n = 210; P = .813). CONCLUSIONS: The BD concept is little known among Ecuadorians residing in Spain, and it is not associated with the attitude toward donation.

RESUMO

INTRODUCTION: New transplant-related therapies such as xenotransplantation of solid cells, tissues, and organs are still poorly understood, especially in countries without preclinical xenotransplantation programs. OBJECTIVE: Analyze the attitude toward xenotransplantation among the population of Santiago de Cuba. METHOD: Type of study. Cross-sectional observational study. SAMPLE: Random sampling of 455 individuals residing in Santiago de Cuba. Assessment instrument. Validated questionnaire of attitude toward the xenotransplant, "PCID-XenoTx-Ríos." Field work. Random selection based on stratification. Anonymous and self-administered completion. RESULTS: A total of 49.9% would accept a solid organ xenotransplant if they needed it and the results were similar to those currently obtained with human organs, 27.5% have doubts, and the remaining 22.6% would not accept it. They are presented as statistically significant variables (P < .05): level of studies; comment with the family about the donation; opinion of a partner; religion; opinion of religion; performing prosocial activities; attitude toward donation; previous relationship with the organ donation and transplant; favorable attitude toward live kidney donation. In the multivariate analysis, the following persist: 1. level of university studies: odds ratio (OR) = 5.076; 2. not having a partner: OR = 5.154; 3. belonging to another religion: OR = 2.061; 4. favorable attitude toward organ donation: OR = 5; and 5. favorable attitude toward living donation: OR = 3.759. CONCLUSIONS: The population of Santiago de Cuba is less sensitized toward xenotransplantation, possibly due to ignorance of the issue due to lack of preclinical trials in their countries.

RESUMO

INTRODUCTION: Puerto Rican and Cuban populations constitute the largest immigrant groups in Florida. This leads to an increase in their involvement in the organ donation and transplantation process (ODT); however, there is very little understanding about their attitude toward and knowledge of related key aspects such as brain death (BD). OBJECTIVE: Analyze knowledge of the BD concept among the Puerto Rican population residing in Florida. MATERIAL AND METHODS: The population under study is born in Puerto Rico and residing in Florida. Inclusion criteria was the population over 15 years stratified by age and sex. The assessment instrument was a validated questionnaire of attitude toward donation and organ transplantation "PCID-DTO-Ríos." A random selection of people was surveyed according to stratification. Support from immigration assistance associations in Florida was needed to locate potential respondents. Survey completion was anonymous and self-administered. RESULTS: Of the 259 respondents, 35% (n = 90) know the BD concept and consider it the death of an individual, 44% (n = 113) do not know it, and 21% (n = 56) do not consider them death. Variables significantly related to the correct knowledge of BD are as follows: sex (P = .012); marital status (P = .043); and couple's opinion (P = .001) and religion (P < .001). In the multivariate analysis, the variables that persist as significant are being married (odds ratio [OR] = 5.231; P = .002); to know the organ donation and transplantation couple attitude as favorable (OR = 4.819; P = .001) and not being Catholic (OR = 4.090; P < .001). CONCLUSIONS: Only one third of the Puerto Rican population residing in Florida knows the concept of BD and accepts it as the death of a person.

RESUMO

INTRODUCTION: The population of Nicaraguan immigrants is growing in North America; however, they have been little analyzed concerning their attitude toward donation and organ transplantation. OBJECTIVE: To analyze the attitude toward the different types of organ donation among the Nicaraguan population residing in Florida. METHODS: Study population. Nicaraguan population residing in Florida (USA). INCLUSION CRITERIA: Population sample over 15 years stratified by age and sex. Instrument valuation. Attitude questionnaires toward organ donation for transplantation "PCID-DTO-Ríos," "PCID-DVR-Ríos," and "PCID-XenoTx-Ríos." Setting for the study. Random selection of people to be surveyed according to stratification. The assistance of immigrant support associations in Florida was required to locate respondents. RESULTS: Sample composed of 89 participants. In the attitude toward donation of one's own organs after death, 22% (n = 20) were in favor, 41% (n = 36) were against, and 37% (n = 33) were undecided. Regarding the donation of living related organs, 76% were in favor (n = 68), 10% were against (n = 9), and 14% were undecided (n = 12). Finally, regarding attitudes toward the acceptance of organ xenotransplantation, if the results were similar to those obtained with human organs, they were not in favor, with 72% (n = 64) against and 28% (n = 25) doubtful. CONCLUSIONS: The attitude of the Nicaraguan population residing in Florida toward different types of organ donation is unfavorable.

RESUMO

INTRODUCTION: Puerto Ricans are one of the majority immigration groups in Florida. However, little is known about their attitudes toward xenotransplantation (XenoTx), a still experimental technique, which is making significant progress. OBJECTIVE: To analyze the attitude toward XenoTx of organs among the population of Puerto Rican residents in Florida. METHODS: Population under study. Sample taken from the International Collaborative Donor Project and formed by the population born in Puerto Rico and resident in Florida. INCLUSION CRITERIA: Over 15 years stratified by age and sex. Instrument valuation. Validated questionnaire of attitude toward xenotransplantation "PCID-XenoTx-Ríos." Setting for the study. Random selection of people to survey based on stratification. Immigrant assistance associations in Florida were consulted to locate potential respondents. RESULTS: Of the 259 respondents, 16% are in favor of XenoTx if the results are similar to those obtained with human organs, 74% are against, and 10% are doubtful. If the results are worse than with human organs, only 2% are in favor, 74% against, and 24% undecided. The variables that are associated with this attitude are the following: sex (P = .001); marital status (P < .001); have offspring (P = .004); level of education (P < .001), opinion of a partner toward donation (P = .008), religious beliefs (P < .001), knowing the opinion toward donation of religion (P < .001), prosocial activity (P < .001), attitude toward donation (P ≤ .001), previous relationship with donation (P < .001), possibility of receiving a transplant in the future (P = .001), and attitude toward donation to a relative (P < .001). CONCLUSIONS: The Puerto Rican population residing in Florida does not hold a favorable attitude toward xenotransplantation.

RESUMO

INTRODUCTION: The favorable knowledge of the concept of brain death (BD) is a determinant for organ donation. OBJECTIVE: To analyze the level of knowledge of the concept of BD in the population of Cienfuegos (Cuba) and determine the factors that condition it. METHODS: Sample of Cubans residing in Cienfuegos (n = 636) stratified by age and sex. The assessment instrument is the validated questionnaire of attitude toward donation and transplant, "PCID-DTO-Ríos," self-administered and anonymously filled out. STATISTICS: χ2, Student t test, and a logistic regression analysis. RESULTS: A total of 636 individuals completed the questionnaire. Fifty percent of participants understood the concept of BD and accept it as a person's death (n = 318). Of the rest, 13.4% (n = 85) did not understand it, and 36.6% (n = 233) had a misconception. The marital status (be married and / or with a partner) of the respondent is associated with the knowledge BD (P < .001) as are the following variables: level of education; offspring; having discussed the issue of donation and transplantation with the family; opinion of the couple toward donation and transplantation; religion; and favorable attitude toward the organ donation and transplant. In the multivariate analysis, the following are independent variables: 1. studies (odds ratio [OR] = 4.664; P = .002); 2. has no offspring (OR = 3.129; P < .001); 3. has commented on it in the family nucleus (OR = 2.759; P < .001); 4. despite having an opinion against (OR = 16.999; P < .001); 5. religion (OR = 1.878; P = .042); and 6. favorable attitude toward the donation of cadaver organs (OR = 2.026; P = .011). CONCLUSIONS: Half of the population of Cienfuegos knows and accepts the concept of BD as the death of an individual, associating said acceptance with a favorable attitude toward organ donation.

RESUMO

INTRODUCTION: Ecuadorians are the largest immigrant group in Spain. In countries with preclinical programs of xenotransplantation (XenoTx), it is important to know the population attitude toward them; however, in the Ecuadorian population it is not known. OBJECTIVE: To analyze the attitude toward XenoTx of organs among the Ecuadorian population residing in Spain. METHODS: Population under study. Ecuadorians residing in Spain. INCLUSION CRITERIA: Sample of population over 15 years stratified by age and sex. Instrument valuation. Validated questionnaire of attitude towards xenotransplantation PCID-XenoTx-Ríos. Setting for the study. Random selection of people to survey based on stratification. RESULTS: Of the 461 respondents, 36% are in favor of XenoTx if the results were similar to those obtained with humans, 15% against, and 49% undecided. If the results were worse than with human organs, 11% would be in favor, 26% against, and 63% undecided. The variables associated with this attitude are age (P = .018), marital status (P = .026), studies (P < .001), comment with family (P = .001), couple attitude (P = .039), attitude toward cadaveric donation (P < .001), previous experience with donation (P = .001), consider the possibility of needing a transplant in the future (P < .001), and attitude toward related living donation (P < .001). In the multivariate analysis, these data persist: university studies (odds ratio [OR] = 3.875; P = .007); in favor of cadaveric organ donation (OR = 2.840; P < .001); previous relationship with donation and organ transplantation (OR = 1.901; P = .026); and consider the possibility of needing a transplant in the future (OR = 4.329; P = .002). CONCLUSIONS: The attitude toward XenoTx among Ecuadorian residents in Spain is unfavorable and is conditioned by different psychosocial variables.

RESUMO

The present dominant trend of retreating and shrinking glaciers is leading to the formation of new soil in proglacial zones. The Cordillera Blanca located in the Peruvian Andes includes the Lake Parón catchment known for the Artesonraju Glacier and its rapid retreat, forming the largest proglacial lake in the region. This work aims to gain knowledge of soil and vegetation development on the most representative proglacial landforms existing in the Parón catchment. Previous research in proglacial environments suggests that soil properties might indicate different ages of ice retreat besides the normalised difference vegetation index (NDVI), which is known to be a powerful tool for assessing vegetation development. In the area surrounding Lake Parón up to the glacier tongue, an altitudinal transect (4200-4700 m a.s.l.) was established for sampling topsoils. A total of 40 surface soil samples (0-3 cm) were collected from the main glacial landforms, moraines, colluvium, glacio-fluvial terraces and alluvial fans, developed after different stages of glacier retreat. Soil organic carbon (SOC) and SOC fractions (active and stable), total nitrogen (TN) and 137Cs were analysed. A multitemporal analysis of NDVI was performed to assess the vegetation dynamics in the Parón catchment and over the different glacial landforms over time (1987-2018). The NDVI increase in recent decades indicates an expansion of vegetation cover and density. We compared NDVI values with the SOC and TN content to assess the relationships with vegetation growth in mountain soils. NDVI and the distribution of SOC and TN content show a positive correlation between vegetation evolution and the enrichment in soil nutrients that are more abundant in older moraines in coincidence with highest NDVI. These results outline the effect of shrinking mountain glaciers on generating new soils in parallel with the growth of vegetation.

RESUMO

Paciente masculino, hipertenso con inicio súbito de trastornos de movimientos hipercineticos, involuntarios, continuos e irregulares, de la cabeza y hemicuerpo izquierdo. Cursó con afectación de diversos segmentos corporales, principalmente la porción distal de las extremidades, que disminuyen significativamente durante el sueño y se exacerban con emociones, stress o alta concentración. Este trastorno puede tener múltiples causas: genéticas, degenerativas, cerebrovasculares, metabólicas, endocrinas, tóxicas y medicamentosas; en este caso no hay historia de consumo de tóxicos o medicamentos, ni tampoco, datos de causas metabólicas como hiper o hipoglicemia, hipercalcemia significativa o hipernatremia o hiponatremia, entre otras. Se descartó la etiología degenerativa por el curso agudo de la enfermedad. Las imágenes tomográficas fueron compatibles con hemorragia mesencefálica, lo cual motiva esta presentación por lo infrecuente de los trastornos del movimiento involuntario tras un ictus, aunque está descrita en la bibliografía(AU)

We describe a male patient, with hypertension, who consulted for sudden onset of continuous hemichoreic movements of the head and left side of the body. These movements diminished during the sleep and exacerbated with emotions, stress or alertness. Usually this clinical presentation can be due to genetic, degenerative, cerebrovascular events, metabolic causes, medications, toxic substances and several electrolytic disturbances. None of the later were found in this patient, and degenerative origin was not an option due to the sudden onset of his symptoms. The brain cat-scan showed a mesencephalic hemorrhage, which is infrequent with this clinical presentation(AU)

RESUMO

ABSTRACT Purpose: to characterize the reading alterations in individuals with attention deficit hyperactivity disorder. Methods: PubMed and SciELO platforms from 2006 to 2016 with the keywords "reading" and "attention deficit hyperactivity disorder", with their equivalents in Portuguese, were searched. Results: seven hundred ninety articles were found in the two databases, of which 119 were relevant. After a full reading, twenty five articles were selected for the analysis, according to relevance and other exclusion/inclusion criteria. In 21 of the studies, individuals with attention deficit hyperactivity disorder presented worse performance in reading, as compared with their peers. Of these, 14 studies identified a delay in some skills that are important for reading: processing speed, reading accuracy, phonological awareness, comprehension and/or orthographic processing. Conclusion: these results corroborate other studies that have verified the presence of a deficit in academic performance, especially in reading skills, in individuals with attention deficit hyperactivity disorder, that may persist in their adulthood.

RESUMO Objetivo: caracterizar as alterações de leitura presentes em indivíduos com Transtorno do Déficit de Atenção e Hiperatividade. Métodos: foram realizadas buscas de publicações nas plataformas PubMed e SciELO de 2006 a 2016 com as palavras-chaves "leitura" e "transtorno do déficit de atenção e hiperatividade", com seus equivalentes em inglês. Resultados: foi encontrado 790 artigos nas duas bases de dados, nas quais 119 eram mais relevantes. Vinte e cinco artigos foram selecionados para a análise, de acordo com a relevância e outros critérios de exclusão/inclusão. Em 21 publicações os indivíduos com Transtorno do Déficit de Atenção e Hiperatividade apresentaram pior desempenho em leitura, comparando com seus pares. Desses, 14 estudos identificaram atraso em algumas habilidades relevantes para a leitura: velocidade de processamento, precisão de leitura, consciência fonológica, compreensão e/ou processamento ortográfico. Conclusão: estes resultados corroboram outros estudos que verificaram a presença de déficits nas habilidades de leitura em indivíduos com Transtorno do Déficit de Atenção e Hiperatividade que podem permanecer até a fase adulta.
