El català escolar escrit a Catalunya CEsCa

La finalitat del projecte CESCA és proporcionar a la comunitat educativa, al món editorial, a pedagogs, lingüistes i sociolingüistes informació sobre aspectes clau de la llengua escrita activa dels escolars de Catalunya al llarg de l’educació obligatòria. Amb aquest objectiu s’han recollit i processat 2.396 textos produïts per nens i nenes des de l’últim curs d’educació infantil (P5) fins a l’últim curs d’educació obligatòria (4t d’ESO). Els alumnes participants provenen de 30 escoles repartides per tota l’àrea geogràfica de Catalunya, majoritàriament de centres públics, encara que també han participat alguns centres concertats. Els vocabularis, així com els textos de diferents gèneres, estan digitalitzats i organitzats en la base de dades CesCa. Les dades derivades del processament dels vocabularis són consultables a la pàgina web d’accés públic: http://clic.ub.edu/cesca/. Una vegada lematitzades les realitzacions dels cinc dominis semàntics –aliments, activitats de lleure, peces de roba, trets de caràcter i fenòmens de la natura- representats en el vocabulari, s’ha observat que el nombre de lemes augmenta amb el curs escolar de manera sostinguda fins al començament de la secundària per disminuir posteriorment. El domini de trets de caràcter és el més ric en producció de lemes diferents i el domini d’activitats és el que presenta una més gran diversitat de variants. Dos dels resultats obtinguts posen de manifest una certa avantatge del bilingüisme instal•lat al nostre entorn: la més gran quantitat de lemes diferents es troba entre els informants que parlen castellà i català i que diuen parlar català des de sempre. Moltes de les distincions acceptades dins del domini lexicogràfic són difícils d’aplicar a mostres de llengua produïda per parlants en procés d’aprenentatge en un entorn plurilingüe.

Intraobserver and interobserver variability of ascending aorta diameter measurements as assessed by ECG-gated MDCT : automatic versus manual measurements : P15

Purpose: Revolutionary endovascular treatments are on the verge of being available for management of ascending aortic diseases. Morphometric measurements of the ascending aorta have already been done with ECG-gated MDCT to help such therapeutic development. However the reliability of these measurements remains unknown. The objective of this work was to compare the intraobserver and interobserver variability of CAD (computer aided diagnosis) versus manual measurements in the ascending aorta. Methods and materials: Twenty-six consecutive patients referred for ECG-gated CT thoracic angiography (64-row CT scanner) were evaluated. Measurements of the maximum and minimum ascending aorta diameters at mid-distance between the brachiocephalic artery and the aortic valve were obtained automatically with a commercially available CAD and manually by two observers separately. Both observers repeated the measurements during a different session at least one month after the first measurements. Intraclass coefficients as well the Bland and Altman method were used for comparison between measurements. Two-paired t-test was used to determine the significance of intraobserver and interobserver differences (alpha = 0.05). Results: There is a significant difference between CAD and manual measurements in the maximum diameter (p = 0.004) for the first observer, whereas the difference was significant for minimum diameter between the second observer and the CAD (p <0.001). Interobserver variability showed a weak agreement when measurements were done manually. Intraobserver variability was lower with the CAD compared to the manual measurements (limits of variability: from -0.7 to 0.9 mm for the former and from -1.2 to 1.3 mm for the latter). Conclusion: In order to improve reproductibility of measurements whenever needed, pre- and post-therapeutic management of the ascending aorta may benefit from follow-up done by a unique observer with the help of CAD.

Life-threatening versus non-life-threatening manual strangulation: are there appropriate criteria for MR imaging of the neck?

The aim of the study was to determine objective radiological signs of danger to life in survivors of manual strangulation and to establish a radiological scoring system for the differentiation between life-threatening and non-life-threatening strangulation by dividing the cross section of the neck into three zones (superficial, middle and deep zone). Forensic pathologists classified 56 survivors of strangulation into life-threatening and non-life-threatening cases by history and clinical examination alone, and two blinded radiologists evaluated the MRIs of the neck. In 15 cases, strangulation was life-threatening (27%), compared with 41 cases in which strangulation was non-life-threatening (73%). The best radiological signs on MRI to differentiate between the two groups were intramuscular haemorrhage/oedema, swelling of platysma and intracutaneous bleeding (all p = 0.02) followed by subcutaneous bleeding (p = 0.034) and haemorrhagic lymph nodes (p = 0.04), all indicating life-threatening strangulation. The radiological scoring system showed a sensitivity and specificity of approximately 70% for life-threatening strangulation, when at least two neck zones were affected. MRI is not only helpful in assessing the severity of strangulation, but is also an excellent documentation tool that is even admissible in court.

Intraobserver and interobserver variability of ascending aorta diameter as assessed with ECG-gated MDCT: automatic versus manual measurements

Purpose: Recently morphometric measurements of the ascending aorta have been done with ECG-gated MDCT to help the development of future endovascular therapies (TCT) [1]. However, the variability of these measurements remains unknown. It will be interesting to know the impact of CAD (computer aided diagnosis) with automated segmentation of the vessel and automatic measurements of diameter on the management of ascending aorta aneurysms. Methods and Materials: Thirty patients referred for ECG-gated CT thoracic angiography (64-row CT scanner) were evaluated. Measurements of the maximum and minimum ascending aorta diameters were obtained automatically with a commercially available CAD and semi-manually by two observers separately. The CAD algorithms segment the iv-enhanced lumen of the ascending aorta into perpendicular planes along the centreline. The CAD then determines the largest and the smallest diameters. Both observers repeated the automatic measurements and the semimanual measurements during a different session at least one month after the first measurements. The Bland and Altman method was used to study the inter/intraobserver variability. A Wilcoxon signed-rank test was also used to analyse differences between observers. Results: Interobserver variability for semi-manual measurements between the first and second observers was between 1.2 to 1.0 mm for maximal and minimal diameter, respectively. Intraobserver variability of each observer ranged from 0.8 to 1.2 mm, the lowest variability being produced by the more experienced observer. CAD variability could be as low as 0.3 mm, showing that it can perform better than human observers. However, when used in nonoptimal conditions (streak artefacts from contrast in the superior vena cava or weak lumen enhancement), CAD has a variability that can be as high as 0.9 mm, reaching variability of semi-manual measurements. Furthermore, there were significant differences between both observers for maximal and minimal diameter measurements (p<0.001). There was also a significant difference between the first observer and CAD for maximal diameter measurements with the former underestimating the diameter compared to the latter (p<0.001). As for minimal diameters, they were higher when measured by the second observer than when measured by CAD (p<0.001). Neither the difference of mean minimal diameter between the first observer and CAD nor the difference of mean maximal diameter between the second observer and CAD was significant (p=0.20 and 0.06, respectively). Conclusion: CAD algorithms can lessen the variability of diameter measurements in the follow-up of ascending aorta aneurysms. Nevertheless, in non-optimal conditions, it may be necessary to correct manually the measurements. Improvements of the algorithms will help to avoid such a situation.

La força de prensió manual com a factor pronòstic de mortalitat en pacients oncològics terminals a una unitat de cures pal•liatives.

L’objectiu de l’estudi va ser determinar si la força de prensió manual (FPM) era factor pronòstic de mortalitat en malalts amb càncer avançant ingressats a una Unitat de cures pal•liatives (UCP). Es va determinar la força de prensió a l’ingrés i l’evolució de la FPM els primers 12 dies mitjançant un dinamòmetre. Ni la FPM inicial ni a l’evolució va demostrar diferències significatives entre els malalts donats d’alta vius i els que van morir a la UCP. Conclusions: la determinació de FPM no va ser factor pronòstic de supervivència en malalts ingressats per càncer en una UCP.

Manual del aplicador de CO2 en cultivos hortícolas

Este manual se ha solicitado como parte del encargo que Iberdrola realizó al IRTA dentro del proyecto SOST-CO2, financiado por el programa CENIT (Consorcios Estratégicos Nacionales en Investigación Técnica), que forma parte del Programa Ingenio 2010, un proyecto del Gobierno español para incrementar la inversión en I+D, tanto pública como privada, con el objetivo de alcanzar en 2010 el 2% del PIB. El proyecto SOST-CO2 tiene como objetivo abordar el ciclo de vida completo del CO2, desde su captura en las fuentes de emisión pasando por su transporte, su almacenamiento y su valorización a gran escala. Se pretende enlazar la captura del CO2 con su posterior revalorización, buscando así una alternativa sostenible al mero confinamiento geológico de las emisiones. En el contexto del proyecto SOST-CO2, Iberdrola se planteó la utilización directa en horticultura intensiva de gases de combustión procedentes de sus plantas de ciclo combinado que utilizan gas natural como combustible, dado su contenido enriquecido en CO2, y encargó al IRTA su estudio. El objetivo general era, a parte de una importante fijación de carbono por parte de los cultivos, un elevado nivel de sostenibilidad ambiental por reducción de los inputs energéticos empleados en la climatización de los invernaderos y en la depuración de los gases. El trabajo se desarrolló a lo largo de cuatro años (2008-2011) en diversos escenarios experimentales. De las diferentes facetas que abarcó este trabajo, se presentan aquí las más directamente relacionadas con el principal resultado del estudio, es decir, la adecuación de los gases de combustión mencionados para obtener una mejora en la producción y rendimiento por su aplicación en horticultura intensiva.

Manual therapy followed by specific active exercises versus a placebo followed by specific active exercises on the improvement of functional disability in patients with chronic non specific low back pain: a randomized controlled trial.

BACKGROUND: Recent clinical recommendations still propose active exercises (AE) for CNSLBP. However, acceptance of exercises by patients may be limited by pain-related manifestations. Current evidences suggest that manual therapy (MT) induces an immediate analgesic effect through neurophysiologic mechanisms at peripheral, spinal and cortical levels. The aim of this pilot study was first, to assess whether MT has an immediate analgesic effect, and second, to compare the lasting effect on functional disability of MT plus AE to sham therapy (ST) plus AE. METHODS: Forty-two CNSLBP patients without co-morbidities, randomly distributed into 2 treatment groups, received either spinal manipulation/mobilization (first intervention) plus AE (MT group; n = 22), or detuned ultrasound (first intervention) plus AE (ST group; n = 20). Eight therapeutic sessions were delivered over 4 to 8 weeks. Immediate analgesic effect was obtained by measuring pain intensity (Visual Analogue Scale) before and immediately after the first intervention of each therapeutic session. Pain intensity, disability (Oswestry Disability Index), fear-avoidance beliefs (Fear-Avoidance Beliefs Questionnaire), erector spinae and abdominal muscles endurance (Sorensen and Shirado tests) were assessed before treatment, after the 8th therapeutic session, and at 3- and 6-month follow-ups. RESULTS: Thirty-seven subjects completed the study. MT intervention induced a better immediate analgesic effect that was independent from the therapeutic session (VAS mean difference between interventions: -0.8; 95% CI: -1.2 to -0.3). Independently from time after treatment, MT + AE induced lower disability (ODI mean group difference: -7.1; 95% CI: -12.8 to -1.5) and a trend to lower pain (VAS mean group difference: -1.2; 95% CI: -2.4 to -0.30). Six months after treatment, Shirado test was better for the ST group (Shirado mean group difference: -61.6; 95% CI: -117.5 to -5.7). Insufficient evidence for group differences was found in remaining outcomes. CONCLUSIONS: This study confirmed the immediate analgesic effect of MT over ST. Followed by specific active exercises, it reduces significantly functional disability and tends to induce a larger decrease in pain intensity, compared to a control group. These results confirm the clinical relevance of MT as an appropriate treatment for CNSLBP. Its neurophysiologic mechanisms at cortical level should be investigated more thoroughly.
