Abstract: Background Algorithms for bone mineral density (BMD) management in HIV-infected patients are lacking. Our objective was to assess how often a dual-energy x-ray absorptiometry (DXA) scan should be performed by assessing time of progression to osteopenia/osteoporosis. Methods All DXA scans performed between 2000 and 2009 from HIV-infected patients with at least two DXA were included. Time to an event (osteopenia and osteoporosis) was assessed using the Kaplan–Meier method. Strata (tertiles) were defined using baseline minimum T scores. Differences between strata in time to an event were compared with the log-rank test. Results Of 391 patients (1,639 DXAs), 49.6% had osteopenia and 21.7% osteoporosis at their first DXA scan. Of the 112 (28.6%) with normal BMD, 35.7% progressed to osteopenia; median progression time was 6.7 years. These patients were stratified: “low-risk" (baseline minimum T score >?0.2 SD), “middle-risk" (between ?0.2 and ?0.6 SD), and “high-risk" (from ?0.6 to ?1 SD); median progression time to osteopenia was 8.7, >7.2, and 1.7 years, respectively (p<0.0001). Of patients with osteopenia, 23.7% progressed to osteoporosis; median progression time was >8.5 years. Progression time was >8.2 years in “low-risk" tertile (T score between ?1.1 and ?1.6 SD), >8.5 years in “middle-risk" (between ?1.6 and ?2), and 3.2 years in “high-risk" (from ?2 to ?2.4) (p<0.0001). Conclusions Our results may help to define the BMD testing interval. The lowest T score tertiles would suggest recommending a subsequent DXA in 1–2 years; in the highest tertiles, ≥6 years. Early intervention in patients with bone demineralization could reduce fracture–related morbidity/mortality.

Abstract: El artículo muestra la gestación de la banca en Zacatecas a partir de los agentes informales de intermediación financiera que explican su establecimiento; la vinculación entre la formación temprana de los bancos regionales antes de la Ley de 1897 y el sector minero; y los agentes socioeconómicos involucrados en los sistemas financieros así como sus estrategias de asociación. Una primera hipótesis es que el sector minero estimuló la configuración de un sistema bancario que respondiera a las necesidades financieras propias del sector y contribuyera a dinamizar las transacciones económicas. En la estructuración del sistema intervinieron agentes con funciones financieras reconocidos en el estado, que denota una parte de la historia de las redes socieconómicas.

Cross-Cultural Communication , 2011, DOI: 10.3968/896
Abstract: This study explored self-concept among 631 adolescents (410 mestizos and 221 indigenous) from the Intercultural University of Chiapas (331), the Autonomous University of Chiapas (150) and University of Altos de Chiapas (150). Our aim was to compare the results of the personal and social self-concept task (PSSC) between the students that participating in these three universities. We predicted, following the MMM approach of culture’s impact on self concept, that students will have different self-concepts because they participating in different educative settings. Specifically, we expected that adolescents who are members of the Intercultural University of Chiapas will score significantly higher on social categories in self-concept task than students who are members of the private University of Altos de Chiapas and Autonomous University of Chiapas. The results supported this hypothesis. We conducted an analysis of variance (ANOVA), showing significant differences in the studied groups. We suggested that proximal process is the mechanism through which culture influences individuals. Key words: Self-Concept; Indigenous; Mestizos; Individualism Versus Collectivism; Proximal Process Resumé: Cette étude a exploré le concept de soi chez 631 adolescents (410 métis et 221 autochtones) venant de l'Université interculturelle du Chiapas (331), l'Université autonome du Chiapas (150) et l'Université d' Altos de Chiapas (150). Notre objectif était de comparer les résultats de la tache du concept de soi personnelle et sociale (CSPC) entre les étudiants de ces trois universités. Nous avions prédit, en suivant l'approche de l'impact de la culture sur le concept de soi, que les élèves ont de différentes conceptions de soi, car ils participent à de différentes institutions éducatives. Plus précisément, nous avons espéré que les adolescents qui sont membres de l'Université interculturelle du Chiapas auraient des notes plus élevées en catégories sociales dans la tache du concept de soi que les étudiants qui sont membres de l'Université privée d' Altos de Chiapas et ceux de l'Université autonome du Chiapas. Les résultats a confirmé cette hypothèse. Nous avons effectué une analyse de variance (Andva), ce qui monte des différences significatives dans les groupes étudiés. Nous avons suggéré que le processus proximal était le mécanisme par lequel la culture influence les individus.

Athenea Digital , 2010,
Abstract: El objetivo que nos proponemos en el siguiente texto es ofrecer una reflexión, desde la psicología cultural, perspectiva teórica desde la que hablamos, alrededor de la interculturalidad como práctica institucionalizada y, por lo tanto, creadora de significados y relaciones. Para ello se exploran algunas producciones narrativas de estudiantes indígenas y mestizos de la Universidad Intercultural de Chiapas (UNICH) alrededor de la discriminación y de su experiencia, antes y después, de participar en dicho escenario sociocultural. Realizamos doce entrevistas en profundidad (historias de vida) a seis mestizos y seis indígenas de dicha universidad. Según el análisis de los significados que emergen en las entrevistas exploradas, interpretamos concluyendo que el contexto de relaciones que se da en la UNICH fomenta la conciliación de los puntos de vista tradicionalmente enfrentados entre indígenas y mestizos a través de la apropiación de un discurso intercultural. In this article we present a qualitative study conducted with six indigenous and six mestizos from Intercultural University of Chiapas. The aim of the study is to exemplify the mutual perception between different ethno-linguistic groups, as well as the possible change occurred after the admission to the University. That is, opinions about the other group after and before entering the University. We conclude that a higher education intercultural model can promote mutual understanding and relationship between indigenous and mestizos and thus combat prejudices and stereotypes.

Abstract: Se evaluó el control de la navajuela en cuatro diferentes estados de desarrollo: (1) dos a tres hojas, (2) inicio del macollamiento, (3) rebrote en cepas adultas luego de cinco semanas de haber sido cortadas con cortadora de motor y (4) cepa adulta o madura. El quinto ensayo combinó cepas adultas y cepas en rebrote. Durante los a os 2002-2005 se realizaron cinco ensayos en Pococí, Limón, dos en invernadero y tres en el campo. Se encontró que la manera más efi caz de eliminar la navajuela sin afectar el pasto fue la aplicación de herbicidas selectivos al pasto, como halosulfuron (75 g/ha), bentazón + MCPA (1.150 g/ha de la mezcla formulada) y ethoxysulfuron (75 g/ha), cuando la maleza se encontraba en estado de dos a tres hojas, lo cual se puede lograr cuando se realiza renovación de pasturas. Por otro lado, para controlar la cepa madura de navajuela fue necesario utilizar herbicidas de amplio espectro, como el diurón + paraquat y el glifosato. Con el glifosato se logró un excelente control tanto en aplicaciones por aspersión como de manera untada o por contacto, con la ventaja de que este último método redujo el da o a la pastura.

Archivos Espa?oles de Urología (Ed. impresa) , 2006, DOI: 10.4321/S0004-06142006000300008
Abstract: objetives: to describe the rate of infectious complications using a discontinuous scheme of oral ciprofloxacin in transurethral resection of the prostate (tur-p). to try to weigh the influence of clinical background, operative complications and postoperative outcome on the development of such complications. to compare the results to those obtained with equal methodology using antibiotics in a continual scheme until the catheter removal. method: a prospective open study was designed including 53 consecutive patients with sterile urine and without indwelling catheter subjected to tur-p. patients received oral ciprofloxacin 500 mg (4 doses) before going to the surgical room, the night of surgery, next morning of surgery and before catheter removal. three patients were excluded after incorporation (5,6%) and all the remainders completed follow up. results: fifty patients are analyzed. fever was present in 8 patients (16%). systemic clinical infection was present in 3 patients (6%). no isolated-germ postoperative bacteriuria was present. previous urinary infection (uti) was statistically associated to systemic clinical infection (p= 0,007) and to active chronic prostatitis on operative biopsy (p= 0,002). conclusion: probably previous uti antecedent made less advisable the discontinuous scheme use in tur-p, although a greater number of patients is needed to confirm these statement. when these results are compared to those using antibiotics in a continual scheme until catheter removal, a significant higher frequency of fever is seen (p= 0,022).

Abstract: objective. in order to investigate the variables that could have the greatest impact on larval indices of aedes aegypti, the main vector of dengue, a descriptive, longitudinal study was carried out in the city of colima, which is located in the mexican pacific coastal state of the same name. methods. a total of 187 dwellings were inspected to determine the house index (hi) and the number of positive containers per house (c+/h), during the rainy season and the dry season. the following were recorded as independent variables: the air temperature, the season, the use of ultra low volume (ulv) spraying of malathion, the premise condition index (pci), and the score on a survey of knowledge, attitudes, and practices (kap). results. both the multivariate logistic regression and the multivariate lineal regression showed a reduction of hi and c+/h due to the effect of the dry season. paradoxically, the temperature seemed to have a negative correlation with the larval indices, and this effect was more pronounced during the dry season. the pci showed the most significant correlation with hi and c+/h, independently of the other variables. the ulv sprayings showed a small negative effect on the indices, while the kap score did not indicate any association at all. conclusions. some conclusions that can be drawn from this study are as follows: higher temperatures can reduce the larval indices during the dry season, the pci can be an adequate estimator of the ae. aegypti infestation rate, ulv spraying reduces the number of larval breeding sites, and the kap score has little association with the larval indices.
