Efectividad del tratamiento con neurofeedback en trastornos del estado del ánimo, ansiedad y fibromialgia: una revisión de literatura

El neurofeedback es una técnica no invasiva en la que se pretende corregir, mediante condicionamiento operante, ondas cerebrales que se encuentren alteradas en el electroencefalograma. Desde 1967, se han conducido numerosas investigaciones relacionadas con los efectos de la técnica en el tratamiento de alteraciones psicológicas. Sin embargo, a la fecha no existen revisiones sistemáticas que reúnan los temas que serán aquí tratados. El aporte de este trabajo es la revisión de 56 artículos, publicados entre los años 1995 y 2013 y la evaluación metodológica de 29 estudios incluidos en la revisión. La búsqueda fue acotada a la efectividad del neurofeedback en el tratamiento de depresión, ansiedad, trastorno obsesivo compulsivo (TOC), ira y fibromialgia. Los hallazgos demuestran que el neurofeedback ha tenido resultados positivos en el tratamiento de estos trastornos, sin embargo, es una técnica que aún está en desarrollo, con unas bases teóricas no muy bien establecidas y cuyos resultados necesitan de diseños metodológicamente más sólidos que ratifiquen su validez.

Comparación de parámetros de atención en una escala de triage de 5 niveles con los parámetros estándar

Introducción: La escala de severidad en emergencias es una herramienta que ofrece seguridad a pacientes en servicios de urgencias. Este trabajo evalúa la aplicación de la escala ESI 4.0 en términos de oportunidad de atención y consumo de recursos en la Fundación Santa Fé de Bogotá, para comparar los resultados con parámetros estándar. Metodología Estudio observacional analítico de corte transversal. Se incluyeron 385 pacientes aleatorizados por nivel de atención. Se tomaron datos demográficos y variables como consumo de recursos y destino del paciente para su descripción y análisis. Resultados: El promedio de edad fue 44.9 años IC95%42.9–46.9, el 54.5% fueron mujeres. Se encontró un tiempo promedio de espera para nivel 1 de 1.39 min, para el nivel 2 de 22.9 min 2, para el nivel 3 de 41.9 min, para el nivel 4 de 56.9 min y para el nivel 5 de 52.1 min. El tiempo promedio de estancia en urgencias fue 5.9 horas y el 78.9% consumió recursos. Al comparar los tiempos con estándares mundiales en el nivel 1, 2 y 3 son significativamente mayores (P<0,05), en el nivel 4 es similar (p0,51) y en el nivel 5 es significativamente menor (p=0,00) Discusión: La escala ESI 4.0 es una herramienta segura, con un comportamiento similar en oportunidad de atención y consumo de recursos con respecto a los estándares de cuidado en los servicios de urgencias.

Step into--the stone age.

Retrocedamos dos millones de años, a la Edad de Piedra y descubriremos como eran los ancestros de los modernos humanos. Dónde vivían los homínidos, como se agrupaban para cazar caballos, bisontes, renos, mamuts peludos que vagaban en grandes manadas por la tundra y las praderas. Se alimentaban de semillas, bayas, frutos secos, raíces, y ya tenían animales domesticados. Nos maravilla las buenas herramientas y armas que fabricaban con distintos materiales y que les ayudaba en su supervivencia. Una serie de actividades prácticas ayuda a los niños a recrear este mundo de la Edad de Piedra.

Artistic education an alternative formative pedagogical and didactic tool: folder, blog

The pedagogical and didactic dynamic system is focused on individual learning process and aims at the development of artistic knowledge, helping and guiding learners through different strategies or individual support, thus reinforcing the process. In consequence, this presentation looks for an alternative to the intercommunication student-teacher supported on the educational paradigm, through textual analyses of the daily diaries, developped by teacher and students, so as to discover successes or difficulties

A teaching/learning support tool for introductory programming courses

In This work we present a Web-based tool developed with the aim of reinforcing teaching and learning of introductory programming courses. This tool provides support for teaching and learning. From the teacher's perspective the system introduces important gains with respect to the classical teaching methodology. It reinforces lecture and laboratory sessions, makes it possible to give personalized attention to the student, assesses the degree of participation of the students and most importantly, performs a continuous assessment of the student's progress. From the student's perspective it provides a learning framework, consisting in a help environment and a correction environment, which facilitates their personal work. With this tool students are more motivated to do programming

An automatic correction tool for relational database schemas

A Web-based tool developed to automatically correct relational database schemas is presented. This tool has been integrated into a more general e-learning platform and is used to reinforce teaching and learning on database courses. This platform assigns to each student a set of database problems selected from a common repository. The student has to design a relational database schema and enter it into the system through a user friendly interface specifically designed for it. The correction tool corrects the design and shows detected errors. The student has the chance to correct them and send a new solution. These steps can be repeated as many times as required until a correct solution is obtained. Currently, this system is being used in different introductory database courses at the University of Girona with very promising results

Exploring chromium (VI) dioxodihalides chemistry: is density functional theory the most suitable tool?

A comparative systematic study of the CrO2F2 compound has been performed using different conventional ab initio methodologies and density functional procedures. Two points have been analyzed: first, the accuracy of results yielded by each method under study, and second, the computational cost required to reach such results. Weighing up both aspects, density functional theory has been found to be more appropriate than the Hartree-Fock (HF) and the analyzed post-HF methods. Hence, the structural characterization and spectroscopic elucidation of the full CrO2X2 series (X=F,Cl,Br,I) has been done at this level of theory. Emphasis has been given to the unknown CrO2I2 species, and specially to the UV/visible spectra of all four compounds. Furthermore, a topological analysis in terms of charge density distributions has revealed why the valence shell electron pair repulsion model fails in predicting the molecular shape of such CrO2X2 complexes

The hardness profile as a tool to detect spurious stationary points in the potential energy surface

The energy and hardness profile for a series of inter and intramolecular conformational changes at several levels of calculation were computed. The hardness profiles were found to be calculated as the difference between the vertical ionization potential and electron affinity. The hardness profile shows the correct number of stationary points independently of the basis set and methodology used. It was found that the hardness profiles can be used to check the reliability of the energy profiles for those chemical system

Fluvial biofilms: a pertinent tool to assess β-blockers toxicity

Among increasingly used pharmaceutical products, β-blockers have been commonly reported at low concentrations in rivers and littoral waters of Europe and North America. Little is known about the toxicity of these chemicals in freshwater ecosystems while their presence may lead to chronic pollution. Hence, in this study the acute toxicity of 3 β-blockers: metoprolol, propranolol and atenolol on fluvial biofilms was assessed by using several biomarkers. Some were indicative of potential alterations in biofilm algae (photosynthetic efficiency), and others in biofilm bacteria (peptidase activity, bacterial mortality). Propranolol was the most toxic β-blocker, mostly affecting the algal photosynthetic process. The exposure to 531 μg/L of propranolol caused 85% of inhibition of photosynthesis after 24 h. Metoprolol was particularly toxic for bacteria. Though estimated No-Effect Concentrations (NEC) were similar to environmental concentrations, higher concentrations of the toxic (503 μg/L metoprolol) caused an increase of 50% in bacterial mortality. Atenolol was the least toxic of the three tested β-blockers. Effects superior to 50% were only observed at very high concentration (707 mg/L). Higher toxicity of metoprolol and propranolol might be due to better absorption within biofilms of these two chemicals. Since β-blockers are mainly found in mixtures in rivers, their differential toxicity could have potential relevant consequences on the interactions between algae and bacteria within river biofilms
