Update and actual trends on bacterial infections following liver transplantation
Jose Luis del Pozo
World Journal of Gastroenterology , 2008,
Abstract: Recent advances in effective antimicrobial prophylactic strategies have led to a decline in the incidence of opportunistic infections in liver transplant recipients. However, morbidity and mortality due to infectious diseases remain as major problems. Bacterial infections occurring early after transplant are mainly related to the technical aspects of the procedure. By contrast, after the first postoperative days and beyond, the nature and variety of infectious complications change. Opportunistic bacterial infections are uncommon after 6 mo in patients receiving stable and reduced maintenance doses of immunosuppression with good graft function and little is documented about these cases in the literature. Transplant recipients may be more susceptible to some pathogens, such as the Nocardia species, Legionella species, Listeria monocytogenes, Mycoplasma species, Salmonella species or Rhodococcus equi. Respiratory infections due to capsulated bacteria, such as Streptococcus pneumoniae and Haemophilus influenza, can be life-threatening if not promptly treated in this population. These late bacterial infections may be very difficult to recognize and treat in this population. In this article, we review what has been described in the literature with regards to late bacterial infections following liver transplantation.

Abstract: grain yield (gy) and drought tolerance of recombinant chromosome substitution lines (rcsls) derived from the cross between hordeum vulgarel.subsp. spontaneum (k. koch) thell. and h. vulgare l. subsp. vulgare cv. harrington, were studied in two contrasting environments, one with water stress (wws) and the other with no water stress (nws), during three growing seasons, 2004-2005, 2005-2006 and 2006-2007. in the first season 80 rcsls were sowed and in the following a selection of 13 rcsls. an a-lattice design was used in all the experiments. with the data of gy obtained in sites wws and nws it was calculated the drought sensitivity index (dsi). during 2004-2005 growing season gy varied greatly among locations, reflecting differences in water availability. the average gy of the 80 rcsls was 4.4 and 8.0 mg ha-1 in sites wws and nws, respectively. the dsi varied between genotypes from 0.24 to 1.53. furthermore, the dsi was negative and significantly correlated with the grain yield obtained in the wws site and allowed to select a group of genotypes tolerant and other sensitive to drought. the group of drought tolerant genotypes yielded in wws 18, 12 and 17% more than the sensitive ones, in 2004-2005, 2005-2006 and 2006-2007 seasons, respectively

Abstract: Se estudiaron 37 pacientes hipertensos esenciales a los cuales se les realizaron 4 investigaciones básicas (electrocardiograma, prueba ergométrica, ecocardiograma y prueba de estimulación por el frío, modificada). A la prueba de estimulación por el frío de Hines y Brown se le introdujo control electrocardiográfico pre y transestimulación, lo cual constituye la modificación realizada. Se valoró su sensibilidad y especificidad en el diagnóstico de cardiopatía en el hipertenso. Se encontró que hubo correlación entre la hipertrofia ventricular izquierda diagnosticada por ecocardiograma y la positividad de la prueba de estimulación por el frío modificada. La sensibilidad de la prueba en cuestión fue del 100 % y la especificidad, del 96 %. Thirty seven patients presenting with essential hypertension were studied.

Abstract: Grain yield (GY) and drought tolerance of recombinant chromosome substitution lines (RCSLs) derived from the cross between Hordeum vulgareL.subsp. spontaneum (K. Koch) Thell. and H. vulgare L. subsp. vulgare cv. Harrington, were studied in two contrasting environments, one with water stress (WWS) and the other with no water stress (NWS), during three growing seasons, 2004-2005, 2005-2006 and 2006-2007. In the first season 80 RCSLs were sowed and in the following a selection of 13 RCSLs. An a-lattice design was used in all the experiments. With the data of GY obtained in sites WWS and NWS it was calculated the drought sensitivity index (DSI). During 2004-2005 growing season GY varied greatly among locations, reflecting differences in water availability. The average GY of the 80 RCSLs was 4.4 and 8.0 Mg ha-1 in sites WWS and NWS, respectively. The DSI varied between genotypes from 0.24 to 1.53. Furthermore, the DSI was negative and significantly correlated with the grain yield obtained in the WWS site and allowed to select a group of genotypes tolerant and other sensitive to drought. The group of drought tolerant genotypes yielded in WWS 18, 12 and 17% more than the sensitive ones, in 2004-2005, 2005-2006 and 2006-2007 seasons, respectively Se estudió el rendimiento de grano (GY) y la tolerancia a la sequía de líneas recombinantes con substitución de cromosomas (RCSLs), provenientes de la cruza entre Hordeum vulgare L. subsp. spontaneum (K. Koch) Thell y H. vulgare L. subsp. vulgare, en dos ambientes contrastantes, uno con estrés hídrico (WWS) y otro sin estrés hídrico (NWS), durante tres temporadas de crecimiento, 2004-2005, 2005-2006 y 2006-2007. En la primera temporada se establecieron 80 RCSLs y en las siguientes se evaluó una selección de 13 RCSLs. Se utilizó un dise o α-latice en todos los experimentos. Con los datos de GY obtenidos en los sitios WWS y NWS se calculó el índice de sensibilidad a la sequía (DSI). Durante la temporada 2004-2005, el GY varió ampliamente entre localidades, reflejando las diferencias en la disponibilidad de agua. El GY promedio de las 80 RCSLs fue 4,4 y 8,0 Mg ha-1 en los sitios WWS y NWS, respectivamente. El DSI varió ampliamente entre genotipos, desde 0,24 hasta 1,53. Además, el DSI se correlacionó negativa y significativamente con el rendimiento de grano en el ambiente WWS y permitió seleccionar un grupo de genotipos tolerantes y otro de sensibles a la sequía. El grupo de genotipos tolerantes a sequía mostró en el sitio WWS un rendimiento de grano promedio de 18, 12 y 7% superior al de los no tolerantes, en las tempora

Abstract: the seedling vigor of 80 barley recombinant chromosome substitution lines (rcsls) was measured for selecting high seedling vigor genotypes. the rcsls were derived from a cross between h. vulgare subsp. spontaneum and h. vulgare subsp. vulgare 'harrington'. the work was carried out under greenhouse conditions during the summer of 2008. the experimental design was an alpha lattice with 3 replicates. in each replicate, 40 plants were established, distributed in eight polyethylene pots containing sand as substrate, which were fertilized an irrigated. the emergence of seedlings, number of leaves and shoots, dry matter of leaves, shoots and roots and leaf area of fully expanded leaves were measured. in addition, growth indices were calculated: emergence rate, leaf appearance rate, relative leaf expansion rate, relative growth rate (rgr), net assimilation rate (nar), leaf area ratio (lar) and the allometric coefficient (k) between root and shoot dry matter. all calculated indices varied significantly among genotypes (p≤0.05) and some rcsls showed better early vigor associated traits than 'harrington'. the dry matter accumulation 30 das (when the experiment ended) was significant and positively correlated with the rgr (r=0.61; p≤ 0.05) and nar (r=0.41; p≤0.05). the k coefficient was negatively correlated with nar (r=-0.40, p≤0.05). the genotypes with the greatest seminal vigor were the rcsls 45, 92, 112 and 'harrington', whereas the rcsls 5, 19, 47 and 121 presented the lowest seminal vigor.

Epidemiología de campo y epidemiología social
Segura del Pozo,Javier;
Gaceta Sanitaria , 2006, DOI: 10.1590/S0213-91112006000200011
Abstract: comparing field epidemiology and social epidemiology, we pretend to think about the no explicit images and meanings operating in both necessary convergent fields, about the obstacles present in epidemiological practice to fulfil its social function and about the necessity of changing epistemological, methodological and practice grounds, beginning with field epidemiologists teaching programmes. field epidemiology would tend to act in an absent theoretical frame. on the other hand, social epidemiology would tend to prioritize theoretical developments (thinking and research about social determinants) without correspondent action, because of the limits to change public policies. other differences are found at intervention level (micro-macrospace), its aim (outbreak control vs. inequalities control) and the way to communicate with society. they are similar in the methodological concern, the predominance of orientation based on positivism and framed through statistic methods, but in process of epistemological opening, the stress experienced between the alternative relationship to a virtual world of data bases or to the real society, their peripherical situation in relation of the political, social, institutional and professional system and the tendency to professional frustration. finally, we ask ten questions to the field epidemiologists related with their present practice, in order to consider if they are developing social epidemiology, and propose some changes in epidemiologist teaching and practice.
LAS RELACIONES ENTRE CHILE Y CANADá DURANTE LA SEGUNDA GUERRA MUNDIAL: LAS PRIMERAS EXPERIENCIAS DE LOS DIPLOMáTICOS CHILENOS
DEL POZO,JOSé;
Historia (Santiago) , 2005, DOI: 10.4067/S0717-71942005000100003
Abstract: based on the reports of the chilean foreign mission in canada, this article deals with the relations between chile and canada during the period in which both countries decided to exchange embassies. it explains that before those years, canada was interested in latin america mainly in commercial topics, while chile showed more interest on the diplomatic side. this difference is due to the fact that chile found itself in a rather vulnerable position before 1939. the second world war was the main reason that led to the establishment of embassies in both countries. the article analyzes also the first impressions of the chilean representatives in ottawa, showing that it was not easy for chilieans to understand the nature of a country like canada. it ends saying that in the short term, the establishment of embassies did not lead to an increase in the commercial or the political relations between both countries
