Abstract: background: no studies have been published to date comparing score, regicor and framingham models. this study is aimed at analyzing how the regicor and score functions classify cardiovascular risk, their correlation and concordance with framingham (1998) and whether any differences exist among them with regard to the cardiovascular risk factors in high-risk groups. methods: descriptive cross-sectional study conducted in primary care. a total of 851 individuals within the 35-74 age range, free of cardiovascular diseases and selected by simple random sampling were included. a study was made of the percentage of high-risk patients with framingham (≥20% ten-year risk), score (≥5% ten-year risk) and regicor with cutoff points ≥20%, ≥15%, ≥10% and ≥5% at 10 years, given that with regicor ≥20% there are hardly any high-risk cases. a comparison was drawn between the correlation (pearson′s r) and concordance (kappa index) of the regicor and score high-risk individuals as compared to framingham. results: the high-risk percentages respectively found were: 23.3% with framingham; 15.2%; with score; and 1.4%, 5.8%, 17.6% and 57.0% with regicor with the cutoff points described. regicor has a 0.99 correlation, score a 0.78 correlation. regicor ≥10% showed a better concordance (kappa 0.83) than score (kappa 0.61). on comparing the cardiovascular risk factors of the high-risk cases (≥20% framingham, ≥5% score and ≥10% regicor), score showed higher prevalence of diabetes and a lower prevalence of hypercholesterolemia (p<0.05). conclusions: regicor showed a good correlation with framingham. with the ≥10% cutoff point, it classifies a number of individuals as high-risk similar to score and fewer than framingham. the score model would treat a number of patients similar to the regicor ≥10% model with hypolipemiant drugs, however showing lesser evidence of effectiveness of the treatment.

Selective Posterior Epiphysiodesis of the Triradiate Cartilage of the Acetabulum: Preliminary Results of an Experimental Study in Rabbits  [PDF]

Abstract: Background: Residual acetabular dysplasia is one of the main complications of developmental dysplasia of the hip (DDH). Without treatment, over time degenerative osteoarthritis of the joint will develop, inexorably leading to the need for joint replacement. Acetabular and/or femoral osteotomies do not avoid the appearance of osteoarthritis in a significant number of patients. The purpose of this study was to assess the possibility of provoking changes in the morphology of the acetabulum through selective epiphysiodesis of the extra-articular portion of the ilioischial arm of the triradiate cartilage, using a percutaneous cannulated screw with the guidance of an imaging intensifier in an experimental model in rabbits. Methods: In a pilot study, 3-week-old New Zealand rabbits (n = 20) were submitted to unilateral surgery of the hip while the contralateral hip of the same group was used as a control. Posterior epiphysiodesis to the triradiate cartilage of the acetabulum was performed by placement of a cannulated screw. The rabbits were followed-up until 18 weeks of life. Radiographic measurements of the hips were performed immediately postoperatively and at 12 weeks of life and before the rabbits were sacrificed at week 18. Three-dimensional computed tomography (3D-CT) scans were performed. Non-parametric tests for paired samples and the Wilcoxon test were used to compare the differences between group 1 and group 2. A p < 0.05 was considered significant. Results: The non-intervened hips showed that, when the rabbit matured, the acetabulum lost concavity and depth. When comparing the median differences of the angles evaluated at 12 weeks between groups, a statistically significant difference was found in all radiographic measurements: an increase in Wiberg’s angle but a decrease in acetabular index, acetabular angle of Sharp, acetabular depth index, and acetabular anteversion. Evaluating the operated hips at 12 and 18 weeks (three months after having removed the screw) using 3D-CT, we observed a rebound effect in the correction confirming that the effect obtained through selective epiphysiodesis did not cause the definitive closure of the cartilage. Conclusions: Selective growth arrest of the ilioischial arm of the triradiate cartilage (posterior epiphysiodesis) can alter growth and change the shape of the acetabulum in rabbits. A rebound effect was observed when the screw was removed, confirming that the technique did not provoke definitive closure of the physis. Level of evidence: Level-2, therapeutic study.

To achieve maximum returns consistent with an investor’s appetite for risk, the correct identification and estimation of all relevant risk factors in a portfolio are necessary. In this paper, we identify the role of foreign currency as an important risk factor from an international investor’s point of view.

Abstract: El artículo aborda el problema de la autoría del Lazarillo de Tormes desde losestudios sobre la Corte, tomando en consideración la lectura en clavecortesana de la obra y la hipótesis presentada en su día por Dalai Brenes Carrillo. En ella se asociaba la figura de Lázaro de Tormes con la del secretario Gonzalo Pérez, y la del misterioso arcipreste de San Salvador con la de Francisco de los Cobos; asociación que, tras una profunda revisión histórica del caso, parece confirmarse, abriendo nuevos caminos al hispanismo para identificar, finalmente, al autor de la novela.The article approaches the problem of the authorship of the Lazarillo de Tormes from the Court studies, Taking in consideration the reading in court key of the work and the hypothesis presented by Dalai Brenes Carrillo. In wich, Lázaro de Tormes's figure was associated with the secretary Gonzalo Perez, as well the figure of the mysterious archpriest of San Salvador was related with Francisco de los Cobos; association that, after a deep historical review of the case, seems to be confirmed, opening new ways for the hispanicism to identify,finally, the author of the novel.
CBS: an open platform that integrates predictive methods and epigenetics information to characterize conserved regulatory features in multiple Drosophila genomes

Abstract: Background Information about the composition of regulatory regions is of great value for designing experiments to functionally characterize gene expression. The multiplicity of available applications to predict transcription factor binding sites in a particular locus contrasts with the substantial computational expertise that is demanded to manipulate them, which may constitute a potential barrier for the experimental community. Results CBS (Conserved regulatory Binding Sites, http://compfly.bio.ub.es/CBS) is a public platform of evolutionarily conserved binding sites and enhancers predicted in multiple Drosophila genomes that is furnished with published chromatin signatures associated to transcriptionally active regions and other experimental sources of information. The rapid access to this novel body of knowledge through a user-friendly web interface enables non-expert users to identify the binding sequences available for any particular gene, transcription factor, or genome region. Conclusions The CBS platform is a powerful resource that provides tools for data mining individual sequences and groups of co-expressed genes with epigenomics information to conduct regulatory screenings in Drosophila.
Psicopatología institucional y minusvalía física.
Ramón Corominas
Revista de la Asociación Espa?ola de Neuropsiquiatría , 1993,
Abstract: Desde un enfoque psicoanalítico, se observa y describe lo que acontece en una Institución. La que el autor analiza se halla dedicada a prestar ayudas, entre ellas incluye la psicoterapia al minusválido físico. Se parte de dos parámetros, personal directivo y Psicólogos clínicos, que desempe an su labor en dicha Institución, analizándose lo que acontece en cada uno de éstos, su psicopatología, así como la que se manifiesta en su interacción. Se se alan algunas ideas de José Bleger en torno a la psicología institucional y se aportan soluciones para que la psicopatología mencionada se reduzca o desaparezca. Se insiste en el papel primordial que el Psicólogo clínico desempe a en el seno de una Institución, actuando como enlace entre los pacientes que a ella acuden y las personas que las dirigen, pues por desgracia, con cierta frecuencia, al analizar a la Institución, se aprecia que se halla luchando contra los principios para los que se creo.
