Experiencias de posgrado sobre el envejecimiento a través de nubes de palabras

La experiencia de posgrado consiste en plantear al estudiantado una reflexión introspectiva a través de nubes de conceptos sobre los principales aspectos que caracterizan la Vejez, con la aplicación social Wordle (http://www.wordle.net). Este software social permite diseñar nubes de etiquetas (tag clouds) de forma dinámica y fácil a partir de los conceptos que se le indica. Se desarrolla con estudiantes que cursan el Máster de Gerontología, Dirección y Gestión de Centros Gerontológicos de la Universidad Pablo de Olavide, durante el curso académico 2012/13. Su enlace es http://mayores3000.jimdo.com/ Entre los objetivos resaltan: reflexionar sobre la acepción de la vejez y el envejecimiento activo, fomentar el papel activo y autónomo de los estudiantes en el proceso de construcción del conocimiento, diseñar y elaborar nubes de ideas previas sobre las concepciones relacionadas con el proceso de Envejecimiento, el uso de software social y elaborar un repositorio de concepciones previas en relación con la Vejez. A través de una metodología cualitativadescriptiva resaltan los siguientes resultados sobre el término de la vejez: Aspectos relacionados con la experiencia (88%), sabiduría (75%), madurez (56%), libertad y desarrollo personal (38%) y la formación y el aprendizaje (25%) con una mayor diferenciación sobre el resto de respuestas reflejadas. Otras características que los estudiantes han asociado al proceso de Envejecer son: Formación, asociada al aprendizaje y el conocimiento (5%), la consideración de que es una etapa, en la que prevalecen los miedos a aspectos tales como enfermedades, a no poder valerse por sí mismos, al trato de terceras personas, a la muerte, y marcada por las oportunidades (4%), otros hacen referencia al concepto de arrugas, años y ocio (3%), así como considerar que es una fase marcada por las emociones, señalando por ejemplo la felicidad, y el sentimiento de plenitud (2%). Por último, atendiendo al alto porcentaje que engloba otros conceptos (17%), señalar que en este apartado se integra: Aficiones, Autonomía Personal, Crecimiento, Cronología, Dependencia, Descanso (merecido), Envejecimiento activo, Familia, Ilusión, Mayores, Posibilidades, Ternura o Vivencias (diferenciada de la experiencia, concretándola en los recuerdos).The university experience consists of raise the introspective reflection through clouds on major concepts that characterize old age with social application Wordle (http://www.wordle.net). This software enables you to design dynamically and easily social tag clouds from the concepts indicated.

Outcomes, controversies and gastric volume after laparoscopic sleeve gastrectomy in the treatment of obesity

AbstractBackgroundLaparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy.Material and methodsA prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study.ResultsThere was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p<0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p<0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series.ConclusionsLaparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique

An analysis of the corporate social responsibility of the spanish marinas

Las Marinas Deportivas son infraestructuras portuarias complejas que agregan valor a las zonas costeras, y que contribuyen al desarrollo económico y social del destino turístico donde se ubican. No obstante, y aunque el estudio de la RSC en el ámbito de las marianas deportivas tienen una gran relevancia tanto a nivel turístico como por sus efectos en el entorno, en la literatura previa sobre RSC, el estudio de los puertos marítimos es escaso y sólo se ha abordado el análisis de su impacto en el medio ambiente. Para cubrir este hueco en la investigación, el objetivo de la presente investigación es analizar el estado actual de la Responsabilidad Social Corporativa de las mariana deportivas españolas, aplicando técnicas de ecuaciones estructurales mediante mínimos cuadrados parciales (PLS-SEM) a la información obtenida de una muestra de 60 puertos deportivos españoles estratificados por tamaño y localización. Los resultados obtenidos han determinado las barreras y los impulsores asociados con la implementación de la RSC en el sector de las marinas deportivas españolas.Universidad de Málaga.

A purL mutant of Sinorhizobium fredii HH103 is symbiotically defective and altered in its lipopolysaccharide

The pleiotropic phenotype of an auxotrophic purL mutant (SVQ295) of Sinorhizobium fredii HH103 has been investigated. SVQ295 forms colonies that are translucent, produce more slime and absorb less Congo red than those of wild-type strain HH103. SVQ295 did not grow in minimal medium unless the culture was supplemented with thiamin and adenine or with thiamin and AICA-riboside (5-aminoimidazole-4-carboxamide 1-b-D-ribofuranoside), an intermediate of purine biosynthesis. Bacterial cultures supplemented with AICA-riboside or adenine reached the same culture density, although the doubling time of SVQ295 cultures containing AICA-riboside was clearly longer. S. fredii SVQ295 induced pseudonodules on Glycine max and failed to nodulate six different legumes. On Glycyrrhiza uralensis, however, nodules showing nitrogenase activity and containing infected plant cells were formed. SVQ295 showed auto-agglutination when grown in liquid TY medium and its lipopolysaccharide (LPS) electrophoretic profile differed from that of its parental strain HH103-1. In addition, four monoclonal antibodies that recognize the LPS of S. fredii HH103 failed to recognize the LPS produced by SVQ295. In contrast, 1H-NMR spectra of K-antigen capsular polysaccharides (KPS) produced by SVQ295 and the wild-type strain HH103 were similar. Co-inoculation of soybean plants with SVQ295 and SVQ116 (a nodA mutant derivative of HH103) produced nitrogen-fixing nodules that were only occupied by SVQ116

Plasma miR-486-5p Expression Is Upregulated in Atrial Fibrillation Patients with Broader Low-Voltage Areas

Atrial fibrillation (AF) is the most common arrhythmia worldwide, affecting 1% of the population over 60 years old. The incidence and prevalence of AF are increasing globally, representing a relevant health problem, suggesting that more advanced strategies for predicting risk stage are highly needed. miRNAs mediate several processes involved in AF. Our aim was to identify miRNAs with a prognostic value as biomarkers in patients referred for AF ablation and its association with LVA extent, based on low-voltage area (LVA) maps. In this study, we recruited 44 AF patients referred for catheter ablation. We measured the expression of 84 miRNAs in plasma from peripheral blood in 3 different groups based on LVA extent. Expression analysis showed that miR-486-5p was significantly increased in patients with broader LVA (4-fold, p = 0.0002; 5-fold, p = 0.0001). Receiver operating characteristic curve analysis showed that miR-486-5p expression could predict atrium LVA (AUC, 0.8958; p = 0.0015). Also, miR-486-5p plasma levels were associated with AF-type (AUC, 0.7137; p = 0.0453). In addition, miR-486-5p expression was positively correlated with LVA percentage, left atrial (LA) area, and LA volume (r = 0.322, p = 0.037; r = 0.372, p = 0.015; r = 0.319, p = 0.045, respectively). These findings suggest that miR-486-5p expression might have prognostic significance in LVA extent in patients with AFThis research was funded by Xunta de Galicia: Programa de Consolidación de Unidades de Investigación Competitivas do SUG (GRC 2019/02), the Centro Singular de Investigación de Galicia acreditación 2019–2022 (ED431G 2019/02), the European Union European Regional Development Fund (ERDF), and National Institute of Health Fondo de Investigaciones Sanitarias, Instituto de Salud Carlos III (ISCIII) Madrid, Spain (PI18/00821, CIBERCV CB16/11/00226 and FAISCA Intramural Project 2019)S

SMEPP: A Secure Middleware For Embedded P2P

Abstract: The increasing presence of embedded devices with internet access capabilities constitutes a new challenge in software development. These devices are now cooperating in a distributed manner towards what has been called as &quot;Internet of Things&quot;. In this new scenario the client-server model is sometimes not adequate and dynamic ad-hoc networks are more common than before. However, security poses as a hard issue as these systems are extremely vulnerable. In this paper, we introduce SMEPP project, which aims at developing a middleware designed for P2P systems with a special focus on embedded devices and security. SMEPP is designed to be deployed in a wide range of devices. It tries to ease the development of applications hiding platforms details and other aspects such as scalability, adaptability and interoperability. A full implementation of this middleware is already available that incorporates security features specially designed for low-resource devices. Moreover, we describe two business applications being developed using this middleware in the context of &quot;Digital Home&quot; and &quot;Environmental Monitoring in Industrial Environments&quot;

Detección Automática de Microaneurismas en Retinografías

La detección de microaneurismas (MA) en retinografías es esencial a la hora de realizar un diagnóstico precoz de la retinopatía diabética (RD). Con esta finalidad, se presenta una herramienta automática que, tras preprocesar la retinografía con métodos basados en intensidad y tras realizar una selección de semillas mediante una umbralización adaptativa, obtiene una serie de candidatos a MA mediante un proceso de crecimiento de regiones, a partir de las cuales se seleccionan los verdaderos MA mediante una clasificación con una red neuronal Fuzzy ARTMAP. La evaluación del algoritmo se ha realizado con una base de datos consistente en 53 retinografías con 256 MA marcados por un oftalmólogo experto. 42 (204 MA) de estas imágenes han sido empleadas para entrenar al clasificador sirviendo las 11 (52 MA) restantes para la fase de prueba. La presente propuesta obtiene una sensibilidad (S) de 78.85% y una media de 9 falsos positivos por imagen (FPpI)
