Kinetic Assessment of Mechanical Properties of a Cellulose Board Aged in Mineral Oil and Synthetic Ester.

In oil-immersed power transformers, the insulation system is constituted of a dielectric oil-solid combination. The insulation oil generally used is mineral oil; however, this fluid has started to be substituted by natural and synthetic esters due to their higher biodegradability and flash point. The introduction of a new fluid in the insulation system of power transformers requires kinetic models that can estimate the degradation rate of insulation solids. The aim of this work was to go further in quantifying through different kinetic models the deterioration suffered by a commercial cellulose board (PSP 3055), which is one of the solid materials used in the insulation system of oil-filled transformers. The aging study was extended to cellulose board specimens immersed in two different oils (mineral and synthetic ester). It was obtained that there is a lower degradation when synthetic ester is used in the insulation system. Additionally, it can be concluded that the use of mechanical properties to quantify the degradation of the cellulose board through kinetic models provides information about the different behavior shown by PSP 3055 when different fiber direction angles are considered.

Assessment of the Grades of Vesicoureteral Reflux in Stented Ureters: An Experimental Study.

INTRODUCTION: The aim of this experimental study is to assess, in a porcine model, the onset and grades of vesicoureteral reflux associated with ureteral stents. METHODS: Twenty-four female porcine models were used. A 4.7-Fr ureteral stent was placed in all right ureters and kept in place for 6 weeks. Follow-ups were performed on weeks 1, 3, 6, and 12. Ultrasonography, cystoscopy, and fluoroscopy were used to analyze grade of hydronephrosis, presence and grade of vesicoureteral reflux, bacteriuria, and macroscopic changes of the ureteral orifices. Vesicoureteral reflux was classified using a modification of the International Reflux Study Committee grades. RESULTS: 91.7% animals present vesicoureteral reflux, 89.5% grade IA, 3.5% grade IB, and 7% grade II. There is a significant increase in reflux during follow-ups at 3 and 6 weeks, whereas 6 weeks after removal, 26.3% of the ureters still present vesicoureteral reflux. Hydronephrosis and macroscopic changes of the ureteral orifice increase significantly with stenting, but there is no significant association between them and vesicoureteral reflux; the relationship between bacteriuria and the presence of vesicoureteral reflux is not significant either. CONCLUSION: Vesicoureteral reflux caused by ureteral stents in an animal model is mostly low grade and mainly affects the distal ureter.

[Is a strategy of bio-socio-ethic necessary?]. / ¿Es necesaria una estrategia integrada de biosocioética?

AIM: The aim of this paper is to assess the need for a common ethics strategy shared by 2 of the cornerstones of human welfare: the healthcare and social services sectors. METHOD: An observational cross-sectional descriptive study was performed by surveying social services and healthcare professionals. A purposive sampling technique was used. The questionnaire consisted of 10 questions about ethical conflicts in professional practice and respondents' views on a proposed shared approach to bioethics and ethics in social intervention. RESULTS: 124 professionals completed the questionnaire, 56% of the health sector and 44% of the social services sector. About 90% professionals surveyed had had to make difficult ethical decisions in their work and would welcome a common approach to ethics in the social services and healthcare sectors. 75% said that conflicts are occurring more frequently in both sectors simultaneously and that they were resolved preferably individually and independently. CONCLUSIONS: The survey respondents believe that a common approach to tackling ethical conflicts in professional practice is required. Nevertheless, it is still rare for ethics committees to intervene in the conflict resolution process and for decision-making support and evaluation tools to be used.

Perceived discrimination among Maghrebi users of health services in Tarragona (Spain).

BACKGROUND: Discrimination in health services for reasons of nationality or ethnicity is not a rare occurrence. This work aims to qualitatively analyse the perceived discrimination among Maghrebi community in Tarragona (Spain) with regard to the healthcare services they receive. METHODS: A qualitative study was carried by means of 12 semi-structured interviews and 10 focus groups with Maghrebi adults living in Tarragona. The scope of the study was public health services in the area. A content analysis was performed using open coding. RESULTS: Our results show that perceived discrimination is greater than actual discrimination because the deficiencies of the healthcare system are often interpreted as unfairness. However, our subjects also recounted incidents of clear discrimination against Maghrebi users of the healthcare system. The tendency to feel discriminated against is the culmination of an interaction between the group's low self-esteem and locals' often negative sentiments towards the group. CONCLUSIONS: We suggest addressing the shortcomings of the healthcare system in order to reduce this level of perceived discrimination and thus improve patient satisfaction. To improve this group's self-esteem and change how they are perceived, public policies should be put into effect which promote social inclusion and the respect for Maghrebis' rights as people, with actions taken on both fronts: in the host society and within the Maghrebi community itself. Furthermore, an active role for the patient with regard to his or her rights should be encouraged in order to minimize abuse from professionals and to facilitate institutional control of individual actions.

Maghrebi minors as translators in health services in Tarragona (Spain): a qualitative study of the discourse of the Maghrebi adults.

BACKGROUND: In the province of Tarragona (Spain), 24% of immigrants come from countries in the Maghreb. 40% of Maghrebis residing in Spain say their linguistic command of Spanish is inadequate, which could hinder their relationship with healthcare professionals. The use of minors as translators by health services is a fairly common practice. The suitability of using children as translators has been questioned, although there has been little specific research on the subject and most has been from the perspective of professionals. The aim of this study was to qualitatively analyze the discourse of Maghrebi adults to the use of Maghrebi minors as translators in the health services. METHODS: A qualitative study using 12 in-depth interviews and 10 focus groups with Maghrebi adults living in Tarragona. The scope of the study was primary healthcare and hospital services in the area. A content analysis was performed using open coding. RESULTS: The practice studied is attributed to a lack of funding for translation resources, and prioritization of adults' work over children's education. It is seen as a convenient solution to the community's communication problems, although it is considered unreliable and detrimental to the rights of the child. The attitudes of healthcare professionals to the phenomenon studied varies from acceptance without any ethical concerns to concern about its effects on the child. The solutions proposed are the organization of translation resources with a proactive approach which are adapted to real needs, and a change in the focus of language training activities for the adults in the community. CONCLUSIONS: It is necessary to reconcile access to healthcare for Maghrebi adults with the rights of children who act as translators in the healthcare context. This requires coordination between health and educational institutions, changes in the organization and provision of translation resources, and a guarantee that immigrants have employment rights under the same conditions as Spanish nationals.
