Dimensions of Self-Construal Associated with Self-Esteem and Depression: A Study among Mexican Students / Dimensiones de La Auto-Definición Asociadas a la Autoestima y Depresión: Un Estudio en Estudiantes Mexicanos

Abstract The relationship between dimensions of self-construal and reported mood states is examined among two samples of Mexican students. Scales focused on seven different aspects of self-construal were employed. Respondents favored predominantly individualistic ways of describing themselves, but also scored high on connection to others. These effects were particularly strong among respondents from Tijuana when compared with those from Mexico City. Depressive mood state was predicted by higher self-reported connection with others, commitment to others, receptiveness to influence and behavioral variability. High self-esteem was predicted by higher self-reported consistency, self-orientation, self-direction and expressiveness.

Resumen La relación entre las dimensiones de la autodefinición y los estados de ánimo auto-reportados fueron evaluados en dos muestras de estudiantes mexicanos. Las escalas que se emplearon se enfocaron en siete diferentes aspectos de la auto-definición. Las respuestas de los participantes favorecieron predominantemente maneras individualistas de describirse a sí mismos, aunque también puntuaron alto en mediciones de conexión con los demás. Estos efectos son particularmente fuertes en los participantes de Tijuana cuando se comparan con los de Ciudad de México. Estados de ánimo depresivos fueron predichos por altos niveles auto-reportados de conexión con otros, compromiso con otros, receptividad a la influencia, y variabilidad conductual. Alta autoestima fue predicha por alta consistencia auto-reportada, auto-orientación, auto-dirección y expresividad.

Culture as perceived context: An exploration of the distinction between dignity, face and honor cultures / La cultura como contexto percibido: explorando la esencia de las culturas de honor, dignidad y autopresentación

Abstract: Researchers are making increasing use of the distinction between cultural logics emphasizing dignity, face, and honor. Students from eight nations including two from Latin America rated items tapping the extent to which they believed that most persons in their nation endorsed these types of mindset. Their ratings did not accord with prior beliefs as to which cultures exemplify dignity, face, and honor. However, the predictions that analytic cognition would be more prevalent in dignity cultures and contrasting types of holistic cognition would be more prevalent in face and honor cultures were supported. The belief that the logic of dignity was prevalent within one's nation was significantly associated with higher life satisfaction.

Resumen: Las investigaciones se están centrando cada vez con mayor énfasis en el uso de la distinción entre lógicas culturales, haciendo más hincapié en la dignidad, el mantenimiento del status quo estructural de una sociedad (face) y el honor. Estudiantes de 8 países, incluyendo 2 de América Latina, clasificaron elementos sobre cuán importante para la aceptación social es la dignidad o el honor para la mayoría de las personas en su nación. Las calificaciones obtenidas no concuerdan con creencias previas en cuanto a cuáles culturas promueven más la dignidad y/o el honor como guías de su comportamiento. Sin embargo, las predicciones de que los patrones de cognición analítica serían más frecuentes en culturas que se centran en la dignidad, y que los patrones de cognición holística serían más frecuentes en culturas que se centran en la honra fueron apoyadas. Adicionalmente, la creencia de que la lógica de la dignidad era frecuente dentro de cada nación se asoció significativamente con una mayor satisfacción de vida.

Clopidogrel use after myocardial revascularization: prevalence, predictors, and one-year survival rate

Abstract Introduction: Antiplatelet therapy after coronary artery bypass graft (CABG) has been used. Little is known about the predictors and efficacy of clopidogrel in this scenario. Objective: Identify predictors of clopidogrel following CABG. Methods: We evaluated 5404 patients who underwent CABG between 2000 and 2009 at Duke University Medical Center. We excluded patients undergoing concomitant valve surgery, those who had postoperative bleeding or death before discharge. Postoperative clopidogrel was left to the discretion of the attending physician. Adjusted risk for 1-year mortality was compared between patients receiving and not receiving clopidogrel during hospitalization after undergoing CABG. Results: At hospital discharge, 931 (17.2%) patients were receiving clopidogrel. Comparing patients not receiving clopidogrel at discharge, users had more comorbidities, including hyperlipidemia, hypertension, heart failure, peripheral arterial disease and cerebrovascular disease. Patients who received aspirin during hospitalization were less likely to receive clopidogrel at discharge (P≤0.0001). Clopidogrel was associated with similar 1-year mortality compared with those who did not use clopidogrel (4.4% vs. 4.5%, P=0.72). There was, however, an interaction between the use of cardiopulmonary bypass and clopidogrel, with lower 1-year mortality in patients undergoing off-pump CABG who received clopidogrel, but not those undergoing conventional CABG (2.6% vs 5.6%, P Interaction = 0.032). Conclusion: Clopidogrel was used in nearly one-fifth of patients after CABG. Its use was not associated with lower mortality after 1 year in general, but lower mortality rate in those undergoing off-pump CABG. Randomized clinical trials are needed to determine the benefit of routine use of clopidogrel in CABG.

Socioeconomic determinants of schistosomiasis in an urban area in the Northeast of Brazil

OBJECTIVE: To identify and quantify the socioeconomic determinants of schistosomiasis in the urban section of Säo Lourenço da Mata, a town in the Northeast of Brazil. METHODS: A cross-sectional study was carried out in 1988 to measure the prevalence of schistosomiasis in Säo Lourenço da Mata among individuals aged 10-25 years and to estimate the socioeconomic characteristics of the households of those individuals. Household aggregation was tested. The data were analyzed on two levels, the family level and the individual level. On the family level we estimated the odds ratios for the association of schistosomiasis and socioeconomic variables related either to the head of the family or to the household. On the individual level we investigated if for the infected individuals there were differences in the intensity of infection (mean egg count) for the different levels of the socioeconomic variables. RESULTS: We found a significant degree of household aggregation of schistosomiasis (allowing for sex and area of residence (neighborhoods with similar socioeconomic conditions, according to census data)). In the analysis on the family level, better socioeconomic indicators for the place in the productive process (occupation, economic sector, and position in production of the head of the family, plus family income) and better socioeconomic indicators for patterns of consumption (level of education of the head of the family, type of housing, household possessions, water supply for the home, sanitation (that is, excreta collection), and family access to medical care) were all associated with a lower risk of schistosomiasis. The estimation of the probability of schistosomiasis for different levels of the socioeconomic variables showed a lower risk (0.072) for individuals whose households were at the top (best) levels of the indicators relative to the risk (0.715) for individuals whose households were at the baseline (lowest) levels of the indicators. Infected individuals whose families had better socioeconomic conditions had lower mean egg count values. CONCLUSIONS: Control measures that may have a long-term effect, such as improvements in the water supply and sanitation, should be strongly encouraged. The theoretical reduction that we found in the probability of being infected if water supply and sanitation were improved highlights the importance of these measures. Implementing them would have a more permanent effect on the control of schistosomiasis and would...

Migration and urban schistosomiasis: the case of São Lourenço da Mata, Northeast of Brazil

A population-based case-control design was used to investigate the association between migration, urbanisation and schistosomiasis in the Metropolitan Region of Recife, Northeast of Brazil. 1022 cases and 994 controls, aged 10 to 25, were selected. The natives and the migrants who come from endemic areas have a similar risk of infection. On the other hand, the risk of infection of migrants from nonendemic areas seems to be related with the time elapsed since their arrival in São Lourenço da Mata; those who have been living in that urban area for 5 or more years have a risk of infection similar to that of the natives. Those arriving in the metropolitan region of Recife mostly emigrate from "zona da mata" and "zona do agreste" in the state of Pernambuco. Due to the changes in the sugar agro-industry and to the increase in the area used for cattle grazing these workers were driven to villages and cities. The pattern of urbanisation created the conditions for the establishment of foci of transmission in São Lourenço da Mata.

Avances en el tratamiento de las taquiarritmias: rol de los métodos no farmacológicos / Advances in the treatment of the tachiarrhythmias: role of nonpharmacological methods

Nonpharmacological methods are a novel therapeutic option for tachiarrhytmias. Transctheter ablation or surgery can cure many arrhythmias, avoiding the collateral effects of antiarrhythmic drugs. Likewise, implantable defibrillators, have changed life expectancy of patients with high risk arrhythmias or sudden survivors. However, the high cost and sophistication of these methods, preclude their widespread use, thus limiting the number of patients that can be benefited. This article reviews the main nonpharmacological techniques for treatment arrhythmias, their results and complications
