Performance of mechanical ventilators at the patient's home: a multicentric quality control study

Background: Quality control procedures vary considerably among the providers of equipment for home mechanical ventilation (HMV). Methods: A multicentre quality control survey of HMV was performed at the home of 300 patients included in the HMV programmes of four hospitals in Barcelona. It consisted of three steps: (1) the prescribed ventilation settings, the actual settings in the ventilator control panel, and the actual performance of the ventilator measured at home were compared; (2) the different ventilator alarms were tested; and (3) the effect of differences between the prescribed settings and the actual performance of the ventilator on non-programmed readmissions of the patient was determined. Results: Considerable differences were found between actual, set, and prescribed values of ventilator variables; these differences were similar in volume and pressure preset ventilators. The percentage of patients with a discrepancy between the prescribed and actual measured main ventilator variable (minute ventilation or inspiratory pressure) of more than 20% and 30% was 13% and 4%, respectively. The number of ventilators with built in alarms for power off, disconnection, or obstruction was 225, 280 and 157, respectively. These alarms did not work in two (0.9%), 52 (18.6%) and eight (5.1%) ventilators, respectively. The number of non-programmed hospital readmissions in the year before the study did not correlate with the index of ventilator error. Conclusions: This study illustrates the current limitations of the quality control of HMV and suggests that improvements should be made to ensure adequate ventilator settings and correct ventilator performance and ventilator alarm operation.

The Protein quality control system manages plant defence compound synthesis

Jasmonates are ubiquitous oxylipin-derived phytohormones that are essential in the regulation of many development, growth and defence processes. Across the plant kingdom, jasmonates act as elicitors of the production of bioactive secondarymetabolites that serve in defence against attackers. Knowledge of the conserved jasmonate perception and early signalling machineries is increasing, but the downstream mechanisms that regulate defence metabolism remain largely unknown. Herewe showthat, in the legumeMedicago truncatula, jasmonate recruits the endoplasmic-reticulum-associated degradation (ERAD)quality control system tomanagethe production of triterpene saponins, widespread bioactive compounds that share a biogenic origin with sterols. An ERAD-type RING membraneanchor E3 ubiquitin ligase is co-expressed with saponin synthesis enzymes to control the activity of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), the rate-limiting enzyme in the supply of the ubiquitous terpene precursor isopentenyl diphosphate. Thus, unrestrained bioactive saponin accumulationis prevented and plant development and integrity secured. This control apparatus is equivalent to the ERAD system that regulates sterol synthesis in yeasts and mammals but that uses distinct E3 ubiquitin ligases, of the HMGR degradation 1 (HRD1) type, to direct destruction of HMGR. Hence, the general principles for the management of sterol and triterpene saponin biosynthesis are conserved across eukaryotes but can be controlled by divergent regulatory cues.

Diseño e implementación de una Web dinámica como herramienta para el control de obras en base al coste del proceso de construcción

En la actualidad estamos sufriendo una situación de crisis económica de dimensiones desproporcionadas e inusuales, la cual está obligando a todas las empresas a globalizar en mayor medida el ámbito de actuación de sus negocios, por lo que muchas empresas que trabajaban exclusivamente en el ámbito local o nacional han tenido que expandirse hacia el exterior. Este hecho, añadido a la fortísima competencia existente en el mercado, obligará a todas estas empresas a tener que controlar en mayor medida la actividad productiva, y a hacerlo utilizando tecnologías que faciliten el flujo de la información dentro de la empresa, hagan que la distancia no sea un problema para la transmisión de esa información, y con las que todos los usuarios manejen los mismos datos. El sector de la construcción es uno de los más castigados por la citada crisis, y probablemente uno de los más retrasados en lo que respecta a utilización de Tecnologías de la Información y la Comunicación. El objetivo principal de este trabajo es el diseño e implementación de una web dinámica como herramienta para medir la eficiencia en el control de la actividad productiva de una empresa constructora. La manera de medir esta eficiencia será mediante la comparación mensual de los costes previstos para las diferentes obras que deba ejecutar la empresa (los cuales podemos llamar estándar) y los que se vayan produciendo realmente. La herramienta diseñada podría ir aumentando su utilidad si, añadiendo módulos mediante la ampliación de la base de datos y diseñando las pertinentes nuevas páginas web para el sitio, se usa también para otros menesteres además del control de la actividad productiva por comparación entre costes previstos y reales. Es decir, que se podría llegar a gestionar la información de todas las actividades de la empresa (compras, recursos humanos, contabilidad, gestión de calidad, etc.). Por lo tanto, una web dinámica como la expuesta en el trabajo podría servir como semilla para el desarrollo de un ERP (Enterprise Resource Planning).

The application of the Sedem Diagram Expert System enables selecting excipients with in order to optimize the formula in the preformulation and formulation studies. The methodology is based on the implementation of ICH Q8, establishing the design space of the formula with the use of experiment design, using the parameters of the SeDeM Diagram Expert System as system responses.

Variaciones dimensionales en piezas plásticas de inyección y análisis de los medios de control

En la industria de la automoción, así como en todas las que se dedican a fabricar piezas, ya sean plásticas o de otros materiales, es tan importante la Producción como la Calidad. No sirve de nada fabricar mucho si no son piezas de una calidad adecuada, y del mismo modo no es rentable fabricar muy poco volumen por mucho que tenga una calidad excelente. Por ello hay que buscar siempre el equilibrio entre ambos conceptos. La finalidad es tener procesos lo más robustos posibles que nos permitan fabricar cantidad con una buena calidad. La finalidad de este trabajo es buscar los parámetros que más afectan en un proceso de inyección, es decir, saber cuáles son los que debemos tener bajo control para lograr una calidad de piezas buena y un proceso estable y controlado. Para ver si el proceso es capaz de lograr ese objetivo utilizamos gráficos basados en la teoría de 6- sigma que nos calculan el coeficiente de capacidad del proceso (Cpk). A su vez analizaremos los sistemas de medida que utilizamos en cada una de las piezas analizadas para evaluar si son los correctos y nos permiten discriminar piezas buenas de malas en el proceso productivo. La conclusión del trabajo es que hay que prestar especial atención en controlar aquellos aspectos de un proceso que nos aportan variación, y no invertir tiempo ni dinero en aquellos otros que no nos aportan valor añadido y que no afectan sustancialmente al proceso. Este análisis por supuesto lleva su coste, que he analizado y plasmado en las conclusiones para saber lo que le cuesta aproximadamente a una empresa realizarlo.

Impact of quality improvement tools on the performance of firms using different quality management systems

This study compares the impact of quality management tools on the performance of organisations utilising the ISO 9001:2000 standard as a basis for a quality-management system band those utilising the EFQM model for this purpose. A survey is conducted among 107 experienced and independent quality-management assessors. The study finds that organisations with qualitymanagement systems based on the ISO 9001:2000 standard tend to use general-purpose qualitative tools, and that these do have a relatively positive impact on their general performance. In contrast, organisations adopting the EFQM model tend to use more specialised quantitative tools, which produce significant improvements in specific aspects of their performance. The findings of the study will enable organisations to choose the most effective quality-improvement tools for their particular quality strategy

Predicting overall service quality: a structural equation modelling approach

In this article, the results of a modified SERVQUAL questionnaire (Parasuraman et al., 1991) are reported. The modifications consisted in substituting questionnaire items particularly suited to a specific service (banking) and context (county of Girona, Spain) for the original rather general and abstract items. These modifications led to more interpretable factors which accounted for a higher percentage of item variance. The data were submitted to various structural equation models which made it possible to conclude that the questionnaire contains items with a high measurement quality with respect to five identified dimensions of service quality which differ from those specified by Parasuraman et al. And are specific to the banking service. The two dimensions relating to the behaviour of employees have the greatest predictive power on overall quality and satisfaction ratings, which enables managers to use a low-cost reduced version of the questionnaire to monitor quality on a regular basis. It was also found that satisfaction and overall quality were perfectly correlated thus showing that customers do not perceive these concepts as being distinct

Diagnosi ambiental de les fonts naturals de la zona nord-occidental del Vallès Oriental: el fenomen "garrafaire"

Aquest treball analitza un total de sis fonts naturals situades a la zona nord-occidental del Vallès Oriental amb l’objectiu de determinar-ne la seva freqüentació i en especial centrar-se en el fenomen “garrafaire”. S’ha elaborat un mètode de recompte d’usuaris, s’ha analitzat l’aigua a nivell físico-químic i microbiològic i s’ha portat a terme un sistema de caracterització ambiental d’aquestes fonts. La freqüentació és elevada a quatre de les sis fonts estudiades, de les que només tres són utilitzades habitualment per “garrafaires”. El volum d’ús d’aquestes fonts contrasta amb el control analític de la qualitat de l’aigua, per part de l’administració, que és inexistent en quatre d’elles i insuficient a les restants. La confiança per part dels usuaris cap a la qualitat de l’aigua també difereix dels resultats de les analítiques realitzades, en que l’aigua ha estat qualificada com a no apta per al consum humà en totes elles, exceptuant una única analítica d’una font que ha resultat apta per al consum humà. En conseqüència, caldria un pla de control i seguiment de la qualitat de l’aigua almenys en 4 de les fonts analitzades.
