Complicaciones postoperatorias tempranas de la colporrafia anterior por técnica tradicional versus técnica de sitio específico

El prolapso del piso pélvico es una entidad frecuente, especialmente en pacientes postmenopáusicas y en su gran mayoría requiere tratamiento quirúrgico. En este estudio comparamos la aparición de complicaciones postoperatorias tempranas entre la colporrafia anterior con técnica clásica (TC) versus la colporrafia anterior con técnica de sitio especifico (CSE). Se realizó un estudio observacional analítico, retrospectivo, de dos cohortes de pacientes que requirieron colporrafia anterior entre agosto de 2009 hasta junio de 2012. Las características de cada grupo fueron homogéneas y comparables. El desenlace de mayor frecuencia fue dehiscencia de la línea de sutura, sin embargo, no se encontraron diferencias estadísticamente significativas entre las dos técnicas. La aparición de reprolapso temprano y el diagnóstico de abscesos o hematomas presentaron frecuencias que carecen de diferencia significativa. No hubo complicaciones tempranas graves tales como sangrado intraoperatoria mayor o lesiones vesicouretrales. Los resultados sugieren que las dos técnicas tienen una incidencia baja de complicaciones postoperatorias tempranas y por lo tanto parecen ser seguros dentro del manejo quirúrgico del prolapso del componente anterior del piso pélvico.

Sensibilidad del cuestionario anamnésico de síntomas de miembro superior y columna desarrollado por la unidad de investigación de ergonómica de postura y movimiento (EPM) desde la perspectiva de la fisioterapia en Colombia

El propósito de este estudio es evaluar la sensibilidad, especificidad y valores predictivos del Cuestionario Anamnésico de Síntomas de Miembro Superior y Columna (CASMSC) desarrollado por la Unidad de Investigación de Ergonomía de Postura y Movimiento (EPM). Se realizó un estudio descriptivo de tipo correlacional, mediante el análisis de datos secundarios de una base de datos con registros de trabajadores de la industria de alimentos (n=401) en el año 2013, a quienes se les había aplicado el CASMSC, así como una evaluación clínica fisioterapéutica enfocada en los mismos segmentos corporales; esta última utilizada como prueba de oro. Para analizar si existían diferencias estadísticas por edad, antigüedad y género se aplicó el análisis de varianza de una vía. La sensibilidad, especificidad y valores predictivos del CASMSC se informan con sus respectivos intervalos de confianza (95%). La prevalencia de umbral positivo para sospecha de Desorden Músculo Esquelético (DME) tanto de miembro superior como de columna se encontró muy por encima de la media nacional para el sector. La sensibilidad del CASMSC para miembro superior estuvo en el rango de un 80% a 94,57% y para columna cervical y lumbar fue de 36,4% y 43,4%, respectivamente. Para la región dorsal fue casi del doble de las otras dos regiones (85,7%). El CASMSC es recomendable en su apartado para miembro superior dado a su alto nivel de sensibilidad.

Factores de riesgo asociados a embarazo ectópico

Introducción: El embarazo ectópico es la primera causa de mortalidad materna durante el primer trimestre del embarazo, y la realidad sociocultural de nuestro país indica que las mujeres están exponiéndose cada vez más a factores que aumentan el riesgo para embarazo ectópico. Se pretende evaluar la asociación de los factores de riesgo en una institución de cuarto nivel. Metodología: Se realizó un estudio de casos y controles, con un caso por cada dos controles, escogidos por medio de un muestreo aleatorio simple. Resultados: Se incluyó un total de 200 pacientes. Ambas poblaciones fueron comparables. La edad promedio de casos fue 29 años y de los controles 24.6 años; la mayoría estaban casadas o en unión libre. Con respecto a los factores de riesgo con resultados estadísticamente significativos (p 0,000) se encontró que existe un mayor riesgo de embarazo ectópico con edad entre 18-35 años, estrato socioeconómico bajo, presencia de ETS, estar casada, tener periodo intergenésico prolongado, haber tenido cirugías pélvicas previas, no usar anticonceptivos, tener endometriosis y tener antecedente de embarazo ectópico (p=0,000). El factor de riesgo más alto es el antecedente de un embarazo ectópico previo OR 66.2 IC95% 60.4 – 72.0 seguido de tener endometriosis con OR 20.2 IC95% 18.6 – 21.9. (p 0,000). Discusión: Los factores de riesgo para embarazo ectópico en el presente estudio son concordantes con otros descritos en la literatura. Es importante conocer a fondo los datos presentados para mejorar los índices de esta patología a nivel nacional.

Análisis económico de las vacunas 10-valente y 13-valente contra neumococo: revisión sistemática

Introducción: Las vacunas clásicamente han representado un método económico y eficaz para el control y prevención de múltiples enfermedades infecciosas. En los últimos años se han introducido nuevas vacunas contra neumococo a precios elevados, y los diferentes análisis económicos a nivel mundial de estas vacunas no muestran tendencias. El objetivo de este trabajo era resumir la evidencia existente a través de los diferentes estudios económicos evaluando las dos vacunas de segunda generación contra neumococo en la población a riesgo. Metodología: En este trabajo se realizo una revisión sistemática de la literatura en 8 bases de datos localizadas en diferentes partes del mundo y también que tuvieran literatura gris. Los artículos fueron inicialmente evaluados acorde a su titulo y resumen, posteriormente los elegidos se analizaron en su totalidad. Resultados: Se encontraron 404 artículos, de los cuales 20 fueron incluidos en el análisis final. Se encontró que la mayoría de los estudios se realizaron en áreas donde la enfermedad tiene una carga baja, como es Norte América y Europa, mientras que en los lugares del mundo donde la carga es mas alta, se realizaron pocos estudios. De igual manera se observo que la mayoría de los estudios mostraron por los menos ser costo efectivos respecto a la no vacunación, y en su totalidad las dos vacunas de segunda generación mostraron costo efectividad respecto a la vacunación con PCV-7. Los resultados de los estudios son muy heterogéneos, hasta dentro del mismo país, señalando la necesidad de guías para la conducción de este tipo de estudios. De igual manera, la mayoría de los estudios fueron financiados por farmacéuticas, mientras en un numero muy reducido por entes gubernamentales. Conclusiones: La mayoría de los estudios económicos sobre las vacunas de segunda generación contra neumococo han sido realizados en países con un alto índice de desarrollo económico y patrocinados por farmacéuticas. Dado que la mayoría de la carga de la enfermedad se encuentran en regiones con un menor nivel de desarrollo económico se deberían realizar mas en estas zonas. De igual manera, al ser la vacunación un asunto de salud publica y con un importante impacto económico los gobiernos deberían estar mas involucrados en los mismos.

Evaluación de la disfunción sexual en mujeres con incontinencia urinaria antes y después de la cinta suburetral

Objetivo: Evaluar prospectivamente el grado de disfunción sexual en pacientes con incontinencia urinaria de esfuerzo antes y después de la cinta suburetral libre de tensión mediante el cuestionario PISQ-12 validado en español. Materiales y Métodos: Estudio observacional longitudinal de antes y después. Se seleccionaron 60 mujeres sexualmente activas con algún grado de disfunción sexual, entre abril del 2014 hasta marzo del 2015, diagnosticadas con incontinencia urinaria, programadas para colocación de cinta suburetral transobturadora en el Hospital Universitario Mayor Méderi. La mayoría de las pacientes presentaron algún grado de prolapso genital y requirieron corrección quirúrgica asociada a la cinta. Todas las pacientes respondieron el cuestionario PISQ-12 antes y 6 meses después del procedimiento. Resultados: La edad promedio fue 48 ± 4.58 años. El grado de prolapso con mayor frecuencia fue el estadío II del POP-Q 55% (n=33). El 96.7% (n=50) de las pacientes requirieron además de la colocación de la cinta suburetral corrección quirúrgica del prolapso genital. En la evaluación preoperatoria la disfunción sexual se distribuyó así: Severa: 70%, Moderada 18.3% y Leve 11.7%, después de 6 meses postoperatorios se encontró una diferencia estadísticamente significativa del cambio en el grado de disfunción sexual así: Moderada 41.5% y Leve 58.2% donde ninguna paciente quedó clasificada con disfunción severa. Discusión y Conclusión: Las pacientes que presentaron disfunción sexual severa obtuvieron mayor cambio en el grado de disfunción, luego de la colocación de la cinta suburetral.

Les chroniques d’un Altermuséologue, diffusées régulièrement dans un bulletin, “ Minuit-Express “, auprès d’une vingtaine de muséologues partageant notre intérêt pour la muséologie sociale, à la recherche d’alternatives pour contrer la standardisation de la muséologie actuelle, ont pour but de stimuler la réflexion auprès de nos cadets, de penser autrement. Ces chroniques ont pris les formes suivantes: Commentaires au fil de rencontres et de lectures, reconnaissance de la valeur de travaux de collègues, analyse critique de cheminements personnels quotidiens, courts essais sur des problématiques au coeur de la légitimité de la muséologie en rapport avec sa prise en compte des enjeux de société, la valorisation de la muséologie locale, son insertion dans le monde, le courage du muséologue engagé. Ces jours le jour cherchent enfin à entrer dans l’univers clos d’un muséologue, à favoriser la transparence, la confidence, le partage instantanné de nos processus, de nos états d’âme à l’intérieur d’un mouvement qui se meurt d’ hermétisme et de clostrophobie.

ICT for growth: a targeted approach. Bruegel Policy Contribution 2012/10, June 2012

This Policy Contribution assesses the broad obstacles hampering ICT-led growth in Europe and identifies the main areas in which policy could unlock the greatest value. We review estimates of the value that could be generated through take-up of various technologies and carry out a broad matching with policy areas. According to the literature survey and the collected estimates, the areas in which the right policies could unlock the greatest ICT-led growth are product and labour market regulations and the European Single Market. These areas should be reformed to make European markets more flexible and competitive. This would promote wider adoption of modern data-driven organisational and management practices thereby helping to close the productivity gap between the United States and the European Union. Gains could also be made in the areas of privacy, data security, intellectual property and liability pertaining to the digital economy, especially cloud computing, and next generation network infrastructure investment. Standardisation and spectrum allocation issues are found to be important, though to a lesser degree. Strong complementarities between the analysed technologies suggest, however, that policymakers need to deal with all of the identified obstacles in order to fully realise the potential of ICT to spur long-term growth beyond the partial gains that we report.

On the development of horizontal CEN standards supporting the implementation of EU directives on sludge, soil and biowaste - Project HORIZONTAL

We give an overview on the development of "horizontal" European Committee for Standardisation (CEN) standards for characterising soils, sludges and biowaste in the context of environmental legislation in the European Union (EU). We discuss the various steps in the development of a horizontal standard (i.e. assessment of the possibility of such a standard, review of existing normative documents, pre-normative testing and validation) and related problems. We also provide a synopsis of European and international standards covered by the so-called Project HORIZONTAL. (C) 2004 Elsevier Ltd. All rights reserved.

The standardization of contracts for construction

Contracts are put to a wide variety of uses. Those who draft construction contracts in the UK rarely consider all of the potential uses and therefore may produce documents that are less than ideal. The various uses are considered in their theoretical background before turning to the practical difficulties often encountered in trying to fulfil such diverse aims. The question of standardisation is examined within this context. Existing standard forms of contract in the UK are found to do little to overcome these difficulties, and this encourages either a significant level of amendment to the standards or experienced clients to draft their own forms. The solution is an approach to contract drafting which is designed to offer a compromise; better standard forms, based on the lessons learned from the drafting of non-standard forms and a pooling of experience, including that of lawyers, in the drafting process. Although this paper is based upon the experience of the UK, these conclusions are relevant for contract-drafting practice in general.

A comparison of the active surveillance of scrapie in the European Union

The abattoir and the fallen stock surveys constitute the active surveillance component aimed at improving the detection of scrapie across the European Union. Previous studies have suggested the occurrence of significant differences in the operation of the surveys across the EU. In the present study we assessed the standardisation of the surveys throughout time across the EU and identified clusters of countries with similar underlying characteristics allowing comparisons between them. In the absence of sufficient covariate information to explain the observed variability across countries, we modelled the unobserved heterogeneity by means of non-parametric distributions on the risk ratios of the fallen stock over the abattoir survey. More specifically, we used the profile likelihood method on 2003, 2004 and 2005 active surveillance data for 18 European countries on classical scrapie, and on 2004 and 2005 data for atypical scrapie separately. We extended our analyses to include the limited covariate information available, more specifically, the proportion of the adult sheep population sampled by the fallen stock survey every year. Our results show that the between-country heterogeneity dropped in 2004 and 2005 relative to that of 2003 for classical scrapie. As a consequence, the number of clusters in the last two years was also reduced indicating the gradual standardisation of the surveillance efforts across the EU. The crude analyses of the atypical data grouped all the countries in one cluster and showed non-significant gain in the detection of this type of scrapie by any of the two sources. The proportion of the population sampled by the fallen stock appeared significantly associated with our risk ratio for both types of scrapie, although in opposite directions: negative for classical and positive for atypical. The initial justification for the fallen stock, targeting a high-risk population to increase the likelihood of case finding, appears compromised for both types of scrapie in some countries.

A standardised BCR resistance test for all anticoagulant rodenticides

This paper presents a reappraisal of the blood clotting response (BCR) tests for anticoagulant rodenticides, and proposes a standardised methodology for identifying and quantifying physiological resistance in populations of rodent species. The standardisation is based on the International Normalised Ratio, which is standardised against a WHO international reference preparation of thromboplastin, and allows comparison of data obtained using different thromboplastin reagents. ne methodology is statistically sound, being based on the 50% response, and has been validated against the Norway rat (Rattus norvegicus) and the house mouse (Mus domesticus). Susceptibility baseline data are presented for warfarin, diphacinone, chlorophacinone and coumatetralyl against the Norway rat, and for bromadiolone, difenacoum, difethialone, flocoumafen and brodifacoum against the Norway rat and the house mouse. A 'test dose' of twice the ED50 can be used for initial identification of resistance, and will provide a similar level of information to previously published methods. Higher multiples of the ED50 can be used to assess the resistance factor, and to predict the likely impact on field control.

Allelic size standards and reference genotypes to unify international cocoa (Theobroma cacao L.) microsatellite data

Standardisation of microsatellite allele profiles between laboratories is of fundamental importance to the transferability of genetic fingerprint data and the identification of clonal individuals held at multiple sites. Here we describe two methods of standardisation applied to the microsatellite fingerprinting of 429 Theobroma cacao L. trees representing 345 accessions held in the worlds largest Cocoa Intermediate Quarantine facility: the use of a partial allelic ladder through the production of 46 cloned and sequenced allelic standards (AJ748464 to AJ48509), and the use of standard genotypes selected to display a diverse allelic range. Until now a lack of accurate and transferable identification information has impeded efforts to genetically improve the cocoa crop. To address this need, a global initiative to fingerprint all international cocoa germplasm collections using a common set of 15 microsatellite markers is in progress. Data reported here have been deposited with the International Cocoa Germplasm Database and form the basis of a searchable resource for clonal identification. To our knowledge, this is the first quarantine facility to be completely genotyped using microsatellite markers for the purpose of quality control and clonal identification. Implications of the results for retrospective tracking of labelling errors are briefly explored.

Fruit polyphenols and CVD risk: a review of human intervention studies.

Epidemiological evidence suggests that polyphenols may, in part, explain the cardioprotective properties of fruits. This review aims to summarise the evidence for the effects of fruit polyphenols on four risk factors of CVD: platelet function, blood pressure, vascular function and blood lipids. This review includes human dietary intervention studies investigating fruits and their polyphenols. There was some evidence to suggest that fruits containing relatively high concentrations of flavonols, anthocyanins and procyanindins, such as pomegranate, purple grapes and berries, were effective at reducing CVD risk factors, particularly with respect to anti-hypertensive effects, inhibition of platelet aggregation and increasing endothelial-dependent vasodilation than other fruits investigated. Flavanone-rich fruits, such as oranges and grapefruits, were reported to have hypocholesterolaemic effects, with little impact on other risk factors being examined. However, the evidence was limited, inconsistent and often inconclusive. This is in part due to the heterogeneity in the design of studies, the lack of controls, the relatively short intervention periods and low power in several studies. Details of the polyphenol content of the fruits investigated were also omitted in some studies, negating comparison of data. It is recommended that large, well-powered, long-term human dietary intervention studies investigating a wider range of fruits are required to confirm these observations. Investigations into the potential synergistic effects of polyphenols on a combination of CVD risk markers, dose–response relationships and standardisation in methodology would facilitate the comparison of studies and also provide valuable information on the types of fruits which could confer protection against CVD.

Comparison of methods for analysis of proteolysis by plasmin in milk

Sensitive methods that are currently used to monitor proteolysis by plasmin in milk are limited due to 7 their high cost and lack of standardisation for quality assurance in the various dairy laboratories. In 8 this study, four methods, trinitrobenzene sulphonic acid (TNBS), reverse phase high pressure liquid 9 chromatography (RP-HPLC), gel electrophoresis and fluorescamine, were selected to assess their 10 suitability for the detection of proteolysis in milk by plasmin. Commercial UHT milk was incubated 11 with plasmin at 37 °C for one week. Clarification was achieved by isoelectric precipitation (pH 4·6 12 soluble extracts)or 6% (final concentration) trichloroacetic acid (TCA). The pH 4·6 and 6% TCA 13 soluble extracts of milk showed high correlations (R2 > 0·93) by the TNBS, fluorescamine and 14 RP-HPLC methods, confirming increased proteolysis during storage. For gel electrophoresis,15 extensive proteolysis was confirmed by the disappearance of α- and β-casein bands on the seventh 16 day, which was more evident in the highest plasmin concentration. This was accompanied by the 17 appearance of α- and β-casein proteolysis products with higher intensities than on previous days, 18 implying that more products had been formed as a result of casein breakdown. The fluorescamine 19 method had a lower detection limit compared with the other methods, whereas gel electrophoresis 20 was the best qualitative method for monitoring β-casein proteolysis products. Although HPLC was the 21 most sensitive, the TNBS method is recommended for use in routine laboratory analysis on the basis 22 of its accuracy, reliability and simplicity.

Weaning diet induces sustained metabolic phenotype shift in the pig and influences host response to Bifidobacterium lactis NCC2818

Background The process of weaning causes a major shift in intestinal microbiota and is a critical period for developing appropriate immune responses in young mammals.Objective To use a new systems approach to provide an overview of host metabolism and the developing immune system in response to nutritional intervention around the weaning period.Design Piglets (n=14) were weaned onto either an egg-based or soya-based diet at 3 weeks until 7 weeks, when all piglets were switched onto a fish-based diet. Half the animals on each weaning diet received Bifidobacterium lactis NCC2818 supplementation from weaning onwards. Immunoglobulin production from immunologically relevant intestinal sites was quantified and the urinary (1)H NMR metabolic profile was obtained from each animal at post mortem (11 weeks).Results Different weaning diets induced divergent and sustained shifts in the metabolic phenotype, which resulted in the alteration of urinary gut microbial co-metabolites, even after 4 weeks of dietary standardisation. B lactis NCC2818 supplementation affected the systemic metabolism of the different weaning diet groups over and above the effects of diet. Additionally, production of gut mucosa-associated IgA and IgM was found to depend upon the weaning diet and on B lactis NCC2818 supplementation.ConclusionThe correlation of urinary (1)H NMR metabolic profile with mucosal immunoglobulin production was demonstrated, thus confirming the value of this multi-platform approach in uncovering non-invasive biomarkers of immunity. This has clear potential for translation into human healthcare with the development of urine testing as a means of assessing mucosal immune status. This might lead to early diagnosis of intestinal dysbiosis and with subsequent intervention, arrest disease development. This system enhances our overall understanding of pathologies under supra-organismal control.
