Multi-drug resistance profiles and the genetic features of Acinetobacter baumannii isolates from Bolivia

Introduction: Acinetobacter baumannii is opportunistic in debilitated hospitalised patients. Because information from some South American countries was previously lacking, this study examined the emergence of multi-resistant A. baumannii in three hospitals in Cochabamba, Bolivia, from 2008 to 2009. Methodology: Multiplex PCR was used to identify the main resistance genes in 15 multi-resistant A. baumannii isolates. RT-PCR was used to measure gene expression. The genetic environment of these genes was also analysed by PCR amplification and sequencing. Minimum inhibitory concentrations were determined for key antibiotics and some were determined in the presence of an efflux pump inhibitor, 1-(1-napthylmethyl) piperazine. Results: Fourteen strains were found to be multi-resistant. Each strain was found to have the bla(OXA-58) gene with the ISAba3-like element upstream, responsible for over-expression of the latter and subsequent carbapenem resistance. Similarly, ISAba1, upstream of the bla(ADC) gene caused over-expression of the latter and cephalosporin resistance; mutations in the gyrA(Ser83 to Leu) and parC (Ser-80 to Phe) genes were commensurate with fluoroquinolone resistance. In addition, the adeA, adeB efflux genes were over-expressed. All 15 isolates were positive for at least two aminoglycoside resistance genes. Conclusion: This is one of the first reports analyzing the multi-drug resistance profile of A. baumannii strains isolated in Bolivia and shows that the over-expression of thebla(OXA-58), bla(ADC) and efflux genes together with aminoglycoside modifying enzymes and mutations in DNA topoisomerases are responsible for the multi-resistance of the bacteria and the subsequent difficulty in treating infections caused by them.

Structural Integrity of the Contralesional Hemisphere Predicts Cognitive Impairment in Ischemic Stroke at Three Months

After stroke, white matter integrity can be affected both locally and distally to the primary lesion location. It has been shown that tract disruption in mirror's regions of the contralateral hemisphere is associated with degree of functional impairment. Fourteen patients suffering right hemispheric focal stroke (S) and eighteen healthy controls (HC) underwent Diffusion Weighted Imaging (DWI) and neuropsychological assessment. The stroke patient group was divided into poor (SP; n = 8) and good (SG; n = 6) cognitive recovery groups according to their cognitive improvement from the acute phase (72 hours after stroke) to the subacute phase (3 months post-stroke). Whole-brain DWI data analysis was performed by computing Diffusion Tensor Imaging (DTI) followed by Tract Based Spatial Statistics (TBSS). Assessment of effects was obtained computing the correlation of the projections on TBSS skeleton of Fractional Anisotropy (FA) and Radial Diffusivity (RD) with cognitive test results. Significant decrease of FA was found only in right brain anatomical areas for the S group when compared to the HC group. Analyzed separately, stroke patients with poor cognitive recovery showed additional significant FA decrease in several left hemisphere regions; whereas SG patients showed significant decrease only in the left genu of corpus callosum when compared to the HC. For the SG group, whole brain analysis revealed significant correlation between the performance in the Semantic Fluency test and the FA in the right hemisphere as well as between the performance in the Grooved Pegboard Test (GPT) and theTrail Making Test-part A and the FA in the left hemisphere. For the SP group, correlation analysis revealed significant correlation between the performance in the GPT and the FA in the right hemisphere. Palabras clave

Análisis de series temporales : modelos ARIMA

Este documento es de utilidad como material docente a cualquier estudiante o persona interesada que quiera introducirse en el estudio del análisis de series temporales. Puede ser utilizado como libro de texto en algunas de las asignaturas que se imparten en la licenciatura en Economía y en la licenciatura en Administración de Empresas. Los modelos de series temporales ARIMA constituyen el núcleo del contenido de este documento. Estos modelos se basan en la teoría de los procesos estocásticos que se desarrolla en el capítulo 2. Los modelos ARMA estacionarios se explican con detalle en el capítulo 3 y los modelos ARIMA no estacionarios en el capítulo 4. La metodología de modelización ARIMA con las fases de identificación, estimación y contraste de diagnósticos se explica detalladamente en el capítulo 5 y el capítulo 6 se dedica a la predicción. El capítulo 7 trata sobre la especificación de los modelos de series temporales adecuados a los datos estacionales. Por último, el capítulo 8 reúne una colección de ejercicios para el trabajo propio del lector.

“Aplicación, eficacia y sostenibilidad del programa “Niñ@s en movimiento” en los centros de salud del valle del Txorierri”

Introducción: La incidencia de sobrepeso y obesidad tanto en adultos como en niños ha aumentado considerablemente y con ello la prevalencia de complicaciones. Este incremento se debe a cambios en la sociedad que han creado “el ambiente obesogénico”. Según recientes estudios la obesidad infantil es un factor de riesgo en la aparición de obesidad en la edad adulta. Para evitar esta complicación, hay que realizar intervenciones relacionadas con los estilos de vida. Por lo tanto es importante realizar programas que se basen en la conducta alimentaria, un estímulo de la actividad física, un apoyo emocional y la participación del entorno familiar. El programa “Niñ@s en movimiento" reúne todas las características para ser una intervención eficaz en el tratamiento de la obesidad infantil. Objetivo: Analizar la eficacia y la sostenibilidad de la aplicación del programa “Niñ@s en movimiento" en niños de 7 a 12 años en el valle del Txorierri y determinar la influencia de la salud mental y los hábitos saludables de los padres en relación con la aparición de sobrepeso u obesidad infantil. Metodología: Se realizará un estudio experimental controlado y aleatorizado en el que participan niños con obesidad o sobrepeso de edades comprendidas entre 7 y 12 años y sus familias. Se establecerá una selección no aleatoria y se les asignará aleatoriamente en el grupo control que realizará la terapia convencional o en el grupo experimental en el que se desarrollará el programa “Niños en movimiento”. Se realizarán mediciones de variables antropométricas y psicométricas. La información que se obtenga será introducida en una base de datos informatizada utilizando el sistema SPSS.
