Implicancias del déficit de comunicación en la hora dorada

Se conoce como la hora dorada (Golden Hour) al momento principal donde se pueden salvar las vidas de los pacientes lesionados y en donde se debe recibir atención rápida, oportuna, eficaz dentro de la primera hora de la lesión. El Centro Estratégico de Operaciones (C.E.O) es el encargado de recepcionar todos los llamados y dar respuesta al mismo, activando a los diferentes efectores según corresponda. En la actualidad cuando un llamado ingresa al 911 debido a un accidente de tránsito, lo recepciona la policía, estos toma los datos necesarios para ellos y luego lo deriva al Servicio de Emergencia Coordinado (S.E.C.), de aquí se deriva a un radio operador el cual también registra datos como son: número de teléfono, dirección, y alguna referencia del lugar. Después el llamado se pasa al médico radio operador, el cual evalúa la gravedad del hecho, disponiendo la cantidad de los recursos necesarios (ambulancias, bomberos, policías, etc.) y finalmente el llamado es pasado al despachador, el cual ejecuta las órdenes del médico radio operador y coordinada todo el desplazamiento y el operativo. Dentro de la hora dorada, los primeros minutos son de vital importancia porque desde que ingresa el llamado al 911 hasta que se decide cual será el operativo necesario, está en juego la vida de la víctima del accidente. Todos estos pasos consumen minutos valiosos los cuales deben tratar de acortarse y a su vez aprovecharlos al máximo. Una adecuada recepción de un llamado debe facilitar datos para la ambulancia y haciendo una correcta evaluación de la situación se sabrá si se debe pedir la intervención de otras instituciones o la presencia de más de una ambulancia en el lugar del siniestro. Este trabajo de investigación tiene como objetivo determinar las implicancias que trae al paciente el déficit de comunicación en la hora dorada, en el Servicio Coordinado de Emergencia, Mendoza, en el primer semestre de 2012.Fil: Ramos, Leandro.

In vitro fosfomycin study on concordance of susceptibility testing methods against ESBL and carbapenem-resistant Enterobacteriaceae.

Abstract Objectives The increasing emergence and diffusion of multidrug-resistant (MDR) pathogenic bacteria, both in hospital and community settings, is inducing clinicians to reconsider old antibiotics, such as fosfomycin, to overcome the difficulties posed by these microorganisms. Recent studies have reported good in vitro activity of fosfomycin against extended spectrum s-lactamases (ESBL) and carbapenem-resistant Enterobacteriaceae. The aim of this study was to assess thein vitro activity of fosfomycin by different methods against 120 clinical MDR isolates. Methods Fosfomycin minimum inhibitory concentrations were determined using the agar dilution reference method (AD), gradient test (GT), broth microdilution method (BMD), according to CLSI recommendations, and automated systems (VITEK 2 and BD Phoenix) against 85 carbapenem-resistant Klebsiella pneumoniae and 35 ESBL-producing Escherichia coli. Agreement and discrepancies between the evaluated methods and the reference method were calculated. Results Fosfomycin showed very good activity against ESBL-producing E. coli (88.6%). Excellent agreement (100%) between the three (AD, BMD and GT) susceptibility methods was found for E. coli. No major errors were observed. The fosfomycin resistance rate ranged from 24% (KPC-producing) to 100% (NDM-OXA-48 co-producing) K. pneumoniae. For all carbapenem-resistant K. pneumoniae strains, categorical agreement was >90% for all methods except for VITEK 2, which was 84%. Conclusions When ESBL E. coli isolates are found to be susceptible to fosfomycin with automated systems, it is not necessary to verify these results with the AD reference method; while for resistant strains, the GT can be used. In cases of KPC K. pneumoniae resistant to fosfomycin, the AD method is the only reference method

Variation of the nutritional composition of quinoa according to the processing used

PRE-PRINTS (VERSIÓN FINAL DE AUTOR PARA PUBLICACIÓN). In Mendoza, Argentina, quinoa is grown with a very good yield, and its consumption is becoming widespread. It is consumed as a seed, flour, expanded, sprout (germinated) and activated (hydrated). The popular belief is that all these forms have the same nutritional contribution. Taking into account this belief, the objective of this work was to determine the nutritional composition of the different preparations. The same batch of quinoa seeds was processed as flour, expanded, hydrated and sprout. It was analyzed by triplicate, applying conventional laboratory techniques. For the statistical analysis, a multiple comparison test was applied, and to discriminate between the means, the honestly significant difference procedure (HSD) of Tukey was applied. It showed that there is statistically significant difference of nutrients between all groups, with a level of 95.0% confidence. For proteins, it varies from 12.78±0.02 g/100g in whole seed to 5.25±0.01 g/100g in the hydrated seed. In total fats, it varies from 7.80±0.02 g/100g in flour to 0.72±0.01 g/100g in sprouts. For fiber, the germinated quinoa provides the highest content (23.50±0.01 g/100g), whereas the hydrated quinoa the lowest content (8.71±0.02 g/100 g). The energy value in 100 g was as follows: whole seed 1299 kcal, flour 1430 kcal, germinated 291 kcal, hydrated 594 kcal and expanded 1368 kcal. This shows how different preparations influence the nutritional contribution of quinoa. With this information, one can recommend different types of preparations depending on the type of nutrient which is wanted for consumption

organizational solutions to improve timeliness and effectiveness of the stroke care

Saving time means saving neurons in stroke care process. Managerial and organizational solutions that lean the processes should be considered in order to overcome the effects of stroke, which is the second worldwide cause of death. The purpose of the paper is to understand how Health Lean Management (HLM) can be adopted to achieve a more efficient stroke care process. In this peculiar context, efficiency enhancement leads to safety and effectiveness results. For this reason, the investigated projects have been recognized as Lean & Safety (L&S) projects, being HLM projects reporting patient safety improvements. Due to the peculiarity of the project to investigate, a holistic case study has been conducted in a university hospital of Tuscany region. Thanks to the research framework developed in the literature for L&S projects, data regarding motivations, objectives, organizational and managerial aspects, outcomes, enablers and obstacles of the project have been collected and analysed. A multidisciplinary team, already trained on HLM and supported by the top management, was created and the step-by-step Six Sigma approach was adopted. After a mapping phase, a value stream map was created, Key Performance Indicators were defined and, finally, the Door To Needle (DTN) times and the modified Rankin Scales (mRS) were measured. Thanks to root cause analysis, the identified wastes were analyzed and intervention actions were defined and implemented. They regarded mainly different organizational interventions and they led to a decrease of both DTN times and mRS. The analysed project has demonstrated how it is possible to obtain relevant operational and clinical outcomes through organizational solutions. The analysis of this project, in which pursuing efficiency has led to safety and effectiveness results, has demonstrated how these different performances are linked each other in some peculiar care processes, in which shorter time means more effective and safer care, as in the stroke case. The implementation of L&S projects can improve care processes, providing a contribution to realize a more efficient, effective and safer healthcare system

Development of Jams with Ancestral Seed Aggregates

ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Small-scale food producers have been negatively impacted by the present pandemic and have been forced to use innovations with low-risk products as a means to increase sales. The object was to determine variations in the nutrient profile of peach jam with the introduction of amaranth or quinoa seeds, the latter having been rinsed beforehand to reduce saponin content. Three varieties of the jam were made, and these were subjected to a sensory evaluation by a panel of 30 untrained judges (consumers) and analysed to determine the variation in their composition as a result of the addition of the seeds. To the basic preparation, which consisted of peaches and sugar (PJ), 20% of quinoa seeds were added (QJ) at the bottling stage. To the third jam preparation, amaranth seeds were added in the same proportion (AJ). Official analytical techniques were used to determine their nutrient profile. The protein content increased from 0.23 g% (PJ) to 2.52 g% (QJ) and 3.38 g% (AJ). Total fat increased from 0.35 g% (PJ) to 0.74 g% (QJ) and 1.72 g% (AJ). Fibre increased from 2.13 g% (PJ) to 4.24 g% (QJ) and 2.86 g% (AJ). The incorporation of amaranth and quinoa improved protein profile, fibre and total fat intake and also resulted in a jam with a better nutrient profile, although there was only a slight reduction in carbohydrates, from 68 g% to 66 g%, after the seeds were added. Plum and apricot jam were also tested, and in all instances, the results were similar
