ABSTRACT

Obesity represents a significant global health problem, and reducing its alarmingly high incidence is an urgent challenge. The intragastric balloon is a safe and effective device for weight loss; therefore, it is widely used. Although the frequency of serious complications resulting from its use is low, it is not exempt from them. We would like to present a case of a severe but infrequent complication secondary to this device, with the aim of highlighting the most appropriate procedure in such cases and emphasizing the importance of awareness regarding it.

ABSTRACT

We present the case of an 82-year-old woman with history of right colon adenocarcinoma in whom a routine control scan is performed using a dual-layer detector spectral CT scanner. Conventional CT scan images show a dilated cystic bile duct with no apparent cause of obstruction, finding also no lithiasis inside the gallbladder. Non-calcified gallstones are composed mainly of cholesterol and can have the same radiographic density as bile, making them hard or impossible to spot on conventional CT.

ABSTRACT

Protocatechuic acid (PCA) is the major metabolite of the anthocyanin known as cyanidin 3-glucoside. It is found in plasma and tissues, such as the brain, heart, liver, and kidneys, following consumption of a rich source of this flavonoid. The abnormal pathological assembly of amyloid-ß (Aß) and α-synuclein (αS) is an underlying mechanism involved in the formation of amyloid plaques and Lewy bodies in the brain, which are responsible for neuropathology symptoms in Alzheimer's (AD) and Parkinson's diseases (PD), respectively. This research was performed to evaluate the protective effects of PCA, by establishing its potential role in inhibiting aggregation and fibril destabilization of Aß and αS proteins. It has been found that PCA inhibits the aggregation of Aß and αS and destabilizes their preformed fibrils. These results were confirmed by TEM images, electrophoresis, and immunoblotting experiments. Furthermore, PCA prevents the death of PC12 cells triggered by Aß- and αS-induced toxicity.

ABSTRACT

We studied the timing of writing processes using a direct retrospective online technique, and differences in the textual product from the earliest school years where such a study is feasible to the final years of compulsory education. We also analysed a range of psychological variables to determine their modulating effect on writing. Participants comprised a highly purified sample of 348 students aged between 9 and 16 years old who presented standard development and average levels of curricular and writing competence. Our results reveal complex patterns in the development of the writing process and its orchestration, compared with the textual product, and no direct relationship was observed between development of the writing process and its timing, and improvement in the textual product. Among the youngest students, all this was mediated by psychological variables related to the existence of inaccurate perceptions of self-efficacy as regards the deployment and use of writing processes and causal attributions to external factors. The implications, limitations and future perspectives are discussed


Se investiga la distribución temporal de los procesos de escritura, mediante una técnica on-line de retrospección directa, y diferencias en el producto textual, desde los cursos más inferiores donde es posible atender a su estudio hasta últimos cursos de la enseñanza obligatoria. Además, se atiende al análisis de diversas variables psicológicas para analizar su incidencia moduladora en la escritura. Se utilizó una muestra muy depurada de 348 alumnos, con edades comprendidas entre los 9 y 16 años, con un desarrollo normalizado y unos niveles de competencia curricular y escritora dentro de la media. Los resultados indican patrones complejos de evolución del proceso de escritura y su orquestación, en comparación con el producto escrito, constatando que no existe una traducción directa entre la evolución del proceso de escritura y su distribución temporal, y la mejoría del producto escrito; todo ello mediado por variables psicológicas relacionadas con la presencia de creencias de autoeficacia hacia el despliegue y uso de procesos escritores no calibradas de forma adecuada y la realización de atribuciones causales a factores externos, en los niveles educativos más inferiores. Se discuten las implicaciones, limitaciones y perspectivas futuras

ABSTRACT

El Tapping Test es una prueba neurológica habitual en las evaluaciones de los equipos nacionales de Cuba. Nuestro objetivo fue medir el autocontrol motor con esta prueba y su respuesta psicofisiológica en deportistas de la selección nacional de esgrima de Cuba. Comparando dos versiones del Tapping Test: modo 1 (habitual de lápiz-papel) y modo 2 (versión propuesta ejecutando acción técnica con el arma). Fueron 12 participantes (edadM = 22.19 años, DE = 3.50 años). Se utilizó un equipo de registro psicofisiológico inalámbrico (Biofeedback 2000). Los resultados, indican un autocontrol motor, siendo el modo 1 significativo F(1,10) = 44.29, p < .001; ya que la cantidad de toques o golpes fueron coherentes de acuerdo al ritmo de ejecución. El modo 2 tuvo una motilidad o aceleración significativa en las diferentes fases de la prueba F(1.58,15.8) = 8.14, p = .006, además mostró un mayor nivel de activación psicofisiológica. Este grupo de esgrimistas de alto nivel a pesar del incremento en la activación mostraron un autocontrol motor, ya que controlaron su movimiento de acuerdo al ritmo que se pedía (modo 1) (AU)


The Tapping Test is a common neurological means of evaluating Cuba’s national teams. Our objective was to assess self-control of motor abilities and the athletes’ psychophysiological response by comparing two versions of the tapping test: mode 1 (normal pencil and paper) and mode 2 (technical action with the épée). The participants were made up of 12 athletes from the Cuban National Fencing Team (Mage = 22.19 years, SD = 3.50 years). We used wireless psychophysiological recording equipment (Biofeedback 2000). The results show self-control of motor abilities, mode 1 being significant F(1,10) = 44.29, p < .001 as the number of touches or hits was consistent with the execution rate. Mode 2 showed a motility or significant acceleration in the different phases of the test F(1.586, 15.85) = 8146, p = .006, plus a higher level of psychophysiological activation. This high-ranking group of fencers demonstrated self-control of their motor abilities despite increased activation, controlling their movements to match the requested pace (mode 1) (AU)

ABSTRACT

Antecedentes. Recientemente se ha observado un incremento de las fungemias causadas por especies diferentes de Candida albicans y una disminución de la sensibilidad de los microorganismos responsables al fluconazol. Objetivos. Evaluar la epidemiología y la sensibilidad al fluconazol de los casos de fungemia en España en 2009, comparando los resultados con los obtenidos entre los años 1997-1999 (Pemán J, et al. Eur J Clin Microbiol Infect Dis. 2005). Métodos. Estudio prospectivo multicéntrico con 44 centros participantes realizado desde enero de 2009 a febrero de 2010. Los aislamientos fúngicos procedentes de hemocultivo fueron recogidos en cada centro, donde se realizó el estudio de sensibilidad antifúngica mediante microdilución colorimétrica (Sensititre Yeast One). Resultados. Desde enero de 2009 a febrero de 2010 se recogieron 1.377 aislamientos en hemocultivos, correspondientes a 1.357 episodios de fungemia. Las fungemias se observaron principalmente en mayores de 64 años (46,7%) y el 8,6% en menores de 1 año. C. albicans (44,7%), Candida parapsilosis (29,1%), Candida glabrata (11,5%), Candida tropicalis (8,2%) y Candida krusei (1,9%) fueron las especies más frecuentes, pero su distribución no fue geográficamente homogénea. En los últimos 10 años la incidencia de C. albicans ha aumentado significativamente en Cataluña (39,1 vs. 54,7%, P=0,03) y reducido en la Comunidad Valenciana (49,1 vs. 34,6%, P=0,01). C. parapsilosis ha disminuido en Cataluña (29 vs. 12,4%, P=0,002) y Extremadura (58,3 vs. 20%, P=0,01). La sensibilidad a fluconazol fue similar en toda España pero en los aislamientos de C. albicans la resistencia fue diez veces superior en mayores de 64 años. Sin embargo, la tasa de resistencia (CMI > 32 mg/L) global ha disminuido con respecto a la obtenida hace 10 años (3,7 vs. 2,5% actual), sobre todo en C. albicans (3 vs. 1,6%). Conclusiones. En los últimos 10 años la distribución de las especies causantes de fungemia en España y la sensibilidad al fluconazol no han variado significativamente, aunque se observa una menor tasa de resistencia. La distribución de las especies varía según la unidad de hospitalización, hospital y Comunidad Autónoma(AU)


Background. Recent epidemiological surveillance studies have reported an increase in fungaemia caused by non-Candida albicans species, as well as a decrease in fluconazole susceptibility. Objectives. To evaluate changes in the epidemiology of fungaemia in Spain comparing data from a new surveillance epidemiological study conducted in 2009 with a previous study carried out from 1997 to 1999 (Pemán J, et al. Eur J Clin Microbiol Infect Dis. 2005). Methods. From January 2009 to February 2010, 44 Spanish hospitals participated in a prospective multicentre fungaemia surveillance study to ascertain whether there have been changes in the epidemiology and fluconazole susceptibility. Susceptibility was determined by the colorimetric method Sensititre Yeast One. Demographic and clinical data and the first isolate of each episode were gathered. Results. A total of 1,377 isolates from 1,357 fungaemia episodes were collected, 46.7% from patients older than 64years and 8.6% from children less than 1 year old. C. albicans (44.7%), Candida parapsilosis (29.1%), Candida glabrata (11.5%), Candida tropicalis (8.2%), and Candida krusei (1.9%) were the most frequent species isolated. Distribution varied with the geographical area. C. albicans incidence has increased significantly in the last 10years in Cataluña (39.1 vs. 54.7%, P =0.03) and decreased in the Valencian Community (49.1 vs. 34.6%, P =0.002) and Extremadura (58.3 vs. 20%, P =0.01). Susceptibility to fluconazole was similar for all geographical areas, although resistance in C. albicans was ten times greater for patients aged more than 64years. The overall rate of fluconazole resistance (MIC > 32 mg/L) has decreased with respect to that obtained 10years ago (3.7 vs. 2.5%) mainly in C. albicans (3 vs. 1.6%). Conclusions. In the last ten years, species distribution and fluconazole susceptibility have not significantly changed, although a lower rate of fluconazole resistance has been observed. Species distribution varies with hospital, hospitalization Unit and geographical area(AU)
