A relação de ajuda ao doente em fim de vida e família: o enfermeiro e o cuidar em fim de vida

Os cuidados ao doente em fim de vida tornam-se difíceis de suportar pelas pessoas envolvidas, pois, para além da sobrecarga física, existe um grande desgaste psicológico e emocional, pelo que se torna importante um acompanhamento e apoio por parte dos profissionais de saúde. A relação de ajuda é um elemento decisivo na atividade dos enfermeiros, desempenhando um papel central na resposta às necessidades concretas do doente em fim de vida e sua família. O objectivo do estudo foi identificar necessidades e dificuldades que os enfermeiros enfrentam no contexto da relação de ajuda ao doente em fim de vida e família. A metodologia utilizada foi a Revisão Sistemática da Literatura sendo aplicada a metodologia PICO. Recorreu-se às bases de dados B-on, LILACS e Scielo, tendo sido reunidos 14 artigos e analisados 7. Os resultados mostraram que muitos enfermeiros sentem dificuldade em comunicar com doentes terminais, apesar de valorizarem as relações interpessoais relacionadas com a comunicação, o conforto, o apoio e acompanhamento e as técnicas de alívio do sofrimento do doente e família, direcionadas para a gestão da dor e sofrimento. A falta de formação em cuidados paliativos é evidente, sendo que o desempenho das competências relacionais de ajuda está correlacionado com a formação que os enfermeiros desenvolvem acerca da relação de ajuda. As principais conclusões a que o estudo chegou foram que apesar da dedicação dos enfermeiros a relação de ajuda ao doente terminal e família nem sempre é conseguida. O desenvolvimento pessoal e profissional, o modo como gerem as dificuldades pessoais e relacionais com o doente e família no contexto de fim de vida, são considerados como os ingredientes major ao nível do cuidar e da relação de ajuda profissional.info:eu-repo/semantics/publishedVersio

Biomass-derived carbons physically activated in one or two steps for CH4/CO2 separation

The present study aims at evaluating the suitability of producing activated carbons (ACs) derived from wheat straw by a one-step synthesis approach, as an alternative to more conventional two steps production processes (i.e., pyrolysis and subsequent activation). The performance of the produced ACs, in one or two steps, as sustainable and selective CO2 adsorbents for CH4/CO2 separation is compared. In addition, the influence of pyrolysis conditions on the properties of the resulting two-step ACs is carefully analyzed. We show that the biochar-based precursors of ACs presenting the best textural properties were obtained under mild conditions of maximum temperature and absolute pressure during pyrolysis. The one-step ACs were fully comparable —in terms of textural properties as well as CO2 uptake and selectivity— to those produced by the more conventional two-step synthesis process. In addition, results obtained from breakthrough curve simulations highlight that the best AC in terms of CH4 recovery under dynamic conditions was produced by a one-step activation. Therefore, the one-step process appears to be as an attractive route for the production of engineered carbon materials, which can lead to significant cost savings in large-scale production systems

Determinantes de la eco-innovación en la actividad de costrucción en España

Creative Commons Reconocimiento-NoComercial 3.0 España (CC BY-NC 3.0 ES)[ES] Partiendo del modelo validado por los autores que determina como variables que afectan a la eco-innovación la orientación a procesos, a productos y la obtención de información de fuentes de mercado, identificamos distintos grupos atendiendo al comportamiento eco-innovador de las empresas del sector de la construcción. Utilizando el algoritmo REBUS-PLS aplicado a 222 empresas con datos de PITEC, se detectan 2 grupos, destacando uno más orientado hacia el medioambiente al innovar, con cifras más altas de inversión en I+D así como la ausencia de diferencias significativas en las variables descriptivas (tamaño, cifra de negocios, inversiones, empleados), lo que indica que la eco-orientación al innovar no depende de estas características y sí que va ligada al comportamiento de la empresa. Los resultados tienen importantes aplicaciones prácticas por lo que a las actuaciones de política de promoción de la eco-innovación se refiere, tanto a nivel público como privado.Segarra Oña, MDV.; Peiró Signes, A.; Cervelló Royo, RE.

Unique Organization of the Nuclear Envelope in the Post-natal Quiescent Neural Stem Cells

Neural stem cells (B1 astrocytes; NSCs) in the adult ventricular-subventricular-zone (V-SVZ) originate in the embryo. Surprisingly, recent work has shown that B1 cells remain largely quiescent. They are reactivated postnatally to function as primary progenitors for neurons destined for the olfactory bulb and some corpus callosum oligodendrocytes. The cellular and molecular properties of quiescent B1 cells remain unknown. Here we found that a subpopulation of B1 cells has a unique nuclear envelope invagination specialization similar to envelope-limited chromatin sheets (ELCS), reported in certain lymphocytes and some cancer cells. Using molecular markers, [3H]thymidine birth-dating, and Ara-C, we found that B1 cells with ELCS correspond to quiescent NSCs. ELCS begin forming in embryonic radial glia cells and represent a specific nuclear compartment containing particular epigenetic modifications and telomeres. These results reveal a unique nuclear compartment in quiescent NSCs, which is useful for identifying these primary progenitors and study their gene regulation

Bone Marrow-Derived Cells from Male Donors Do Not Contribute to the Endometrial Side Population of the Recipient

Accumulated evidence demonstrates the existence of bone marrow-derived cells origin in the endometria of women undergoing bone marrow transplantation (BMT). In these reports, cells of a bone marrow (BM) origin are able to differentiate into endometrial cells, although their contribution to endometrial regeneration is not yet clear. We have previously demonstrated the functional relevance of side population (SP) cells as the endogenous source of somatic stem cells (SSC) in the human endometrium. The present work aims to understand the presence and contribution of bone marrow-derived cells to the endometrium and the endometrial SP population of women who received BMT from male donors. Five female recipients with spontaneous or induced menstruations were selected and their endometrium was examined for the contribution of XY donor-derived cells using fluorescent in situ hybridization (FISH), telomapping and SP method investigation. We confirm the presence of XY donor-derived cells in the recipient endometrium ranging from 1.7% to 2.62%. We also identify 0.45–0.85% of the donor-derived cells in the epithelial compartment displaying CD9 marker, and 1.0–1.83% of the Vimentin-positive XY donor-derived cells in the stromal compartment. Although the percentage of endometrial SP cells decreased, possibly being due to chemotherapy applied to these patients, they were not formed by XY donor-derived cells, donor BM cells were not associated with the stem cell (SC) niches assessed by telomapping technique, and engraftment percentages were very low with no correlation between time from transplant and engraftment efficiency, suggesting random terminal differentiation. In conclusion, XY donor-derived cells of a BM origin may be considered a limited exogenous source of transdifferentiated endometrial cells rather than a cyclic source of BM donor-derived stem cells

Exploring the socio-ecological factors behind the (in)active lifestyles of Spanish post-bariatric surgery patients

Purpose: Physical activity (PA) is considered essential for the treatment of morbid obesity and the optimization of bariatric surgery outcomes. The objective of this article was to identify the facilitators and barriers that bariatric patients perceived to do PA one year after finishing a PA programme for the promotion of a long-term active lifestyle. This objective was addressed from a socio-ecological and qualitative perspective. Methods: Nine patients (eight women and one man), aged between 31 and 59 years, participated in semi-structured interviews directly following the PA programme and one year after it. A content analysis was carried out to analyze the qualitative data. Results: Weight loss, improvement of physical fitness, perceived competence, and enjoyment were the main facilitators of PA. Complexes related to skin folds, osteoarthritis, perceived unfavourable weather conditions, lack of social support and economic resources, long workdays, lack of specific PA programmes, and other passive leisure preferences were the main barriers to participate in PA. Conclusions: Results highlight the important interplay between personal, social environmental, and physical environmental factors to explain (in)active behaviours of bariatric patients. The findings of this article could be useful for future research and interventions aimed at promoting PA in bariatric patients

Forecasting Latin America’s Country Risk Scores by Means of a Dynamic Diffusion Model

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.Over the last years, worldwide financial market instability has shaken confidence in global economies. Global financial crisis and changes in sovereign debts ratings have affected the Latin American financial markets and their economies. However, Latin American s relative resilience to the more acute rise in risk seen in other regions like Europe during last years is offering investors new options for improving risk-return trade-offs. Therefore, forecasting the future of economic situation involves high levels of uncertainty. The Country Risk Score (CRS) represents a broadly used indicator to measure the current situation of a country regarding measures of economic, political, and financial risk in order to determine country risk ratings. In this contribution, we present a diffusion model to study the dynamics of the CRS in 18 Latin American countries which considers both the endogenous effect of each country policies and the contagion effect among them. The model predicts quite well the evolution of the CRS in the short term despite the economic and political instability. Furthermore, the model reproduces and forecasts a slight increasing trend, on average, in the CRS dynamics for almost all Latin American countries over the next months.This work has been partially supported by the Spanish M.C.Y.T.
