    Las organizaciones deben llevar a cabo una correcta gestión de la sostenibilidad en sus proyectos. Esta situación incorpora una gran complejidad a su ciclo de vida y un aumento en el volumen de información relativa al proyecto. Por lo que los sistemas PLM (o gestión del ciclo de vida del producto) son una opción adecuada de diseño y desarrollo de proyectos sostenibles y una posible solución en la reducción de la complejidad de gestión de la información. Actualmente los gestores PLM desarrollados ponen a disposición de los diferentes departamentos e interesados (stakeholders) de las organizaciones, toda la información del producto o proyecto en cualquier fase de su ciclo de vida, aunque si analizamos las soluciones en detalle (tanto comerciales como planteadas en la comunidad científica) no existe una herramienta que gestione la sostenibilidad de forma integral y eficiente. Por esta situación en el presente trabajo se identifica y formula una arquitectura de PLM sostenible para la gestión de proyectos en ingeniería, bajo estrategias de gestión de datos que permitan a las empresas identificar los requerimientos de información relevantes para la sostenibilidad del sistema, estableciendo la integración de la información desde la perspectiva de la triple-E (económica, ecológica y social).Organisations must carry out the management of sustainability in their projects in the best efficient way. This situation incorporates a great complexity to the life cycle project and increases the volume of information. For this aspects, PLM system (Product Lifecycle Management) are an appropriate choice of design and development process for sustainable projects and a possible solution to reduce the complexity of managing information. Currently PLM system make available all necessary information to the different departments and stakeholders of organisations. But if we analyse the real solutions in detail (both commercial and model which have been developed in the scientific community) there is any tool to manage the sustainability in a comprehensive and efficient way. For this situation in this paper a PLM architecture for sustainability is developed to carry out sustainable engineering projects under strategies of data management. This PLM Architecture can help companies to identify requirements, organise, distribute and manage all relevant information, thought the perspective of the triple-Bottom line (economic, ecological and social

    El entorno construido ha sido creado para dar soporte a las actividades implicadas en el desarrollo humano. Mejora la habitabilidad sobre el planeta a través de construcciones industriales y urbanas con el objetivo de eliminar las dificultades presentes por la adaptación del ser humano al entorno natural. Una de las características del diseño óptimo de ambientes construidos son las dimensiones del confort (física, psicológica y sociocultural) controladas a través de los factores ambientales como son iluminación, cromatismo, ambiente sonoro o variables termohigrométricas. Todos ellos afectan al bienestar y satisfacción de las personas (bien sean usuarios, o en ambientes laborales trabajadores o clientes). En el presente trabajo se propone una metodología para el diseño experiencial ergocromático del entorno construido de ambientes industriales, incluyendo el espacio de trabajo, de forma que al integrar la dimensión cromática conducida desde el diseño de experiencias, posibilite la fruición y confort de los usuarios. Se pretende incorporar una nueva dimensión en los proyectos de ambientes industriales, teniendo en cuenta aspectos no exclusivamente tecnológicos, sino considerando en la fase de conceptualización, una vertiente de diseño industrial que propicie una mayor armonía entre persona y ambiente a través de la gestión de los aspectos cromáticos del entorno.The built environment has been created to support the activities involved in human development. Industrial and urban construction eliminate the difficulties in the human adaptation to the natural environment and they improve the habitability of the planet. One of the characteristics of the optimal design of built environments are the dimensions of comfort (physical, psychological and sociocultural). They are controlled by environmental factors such as light, colours, noise or thermohigrometric variables. All these affect the welfare and satisfaction people (users or workers and clients in work environments). In this paper a methodology for Experiential ergo-chromatic design of industrial environments is proposed. The methodology integrates the chromatic dimension through experience design to achieve the user comfort. This is a new dimension for industrial projects where is essential to take into account not only technological factors but also the aspects and characteristics for encouraging the harmony between people and the environment through the management of environmental chromatic aspectst

    [Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

    Limited data are available on the effectiveness and tolerability of direct-acting antivirals (DAAs) therapies in the real world for HCV-infected patients with comorbidities. This study aimed to describe the effectiveness of OBV/PTV/r ± DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015.Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records.Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan®, 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient´s decision.These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment. These results are consistent with those reported in clinical trials

    Abstract Background: Combination antiretroviral therapy (cART) has produced significant changes in mortality of HIVinfected persons. Our objective was to estimate mortality rates, standardized mortality ratios and excess mortality rates of cohorts of the AIDS Research Network (RIS) (CoRIS-MD and CoRIS) compared to the general population. Methods: We analysed data of CoRIS-MD and CoRIS cohorts from 1997 to 2010. We calculated: (i) all-cause mortality rates, (ii) standardized mortality ratio (SMR) and (iii) excess mortality rates for both cohort for 100 personyears (py) of follow-up, comparing all-cause mortality with that of the general population of similar age and gender. Results: Between 1997 and 2010, 8,214 HIV positive subjects were included, 2,453 (29.9%) in CoRIS-MD and 5,761 (70.1%) in CoRIS and 294 deaths were registered. All-cause mortality rate was 1.02 (95% CI 0.91-1.15) per 100 py, SMR was 6.8 (95% CI 5.9-7.9) and excess mortality rate was 0.8 (95% CI 0.7-0.9) per 100 py. Mortality was higher in patients with AIDS, hepatitis C virus (HCV) co-infection, and those from CoRIS-MD cohort (1997. Conclusion: Mortality among HIV-positive persons remains higher than that of the general population of similar age and sex, with significant differences depending on the history of AIDS or HCV coinfection
