“Let’s Dance”: A Dialogical Proposal for Analyzing Interactions and Positions in Couples Therapy

The dialogical self theory, based on the metaphor of the self as a dialogue between different voices and I-positions, conceptualizes the structure and functioning of the self as a product of communication and relational processes. The dynamics of the dialogical self imply the articulation between the individual self and the self in relationship with others. Yet, the dialogical self theory has been seldom applied to couples therapy. Therefore, in order to understand changes in relationships from a dialogical perspective, we investigated a case study of a couple – Victoria and Alfonso – evolving through four sessions of couple’s therapy.info:eu-repo/semantics/publishedVersio

A reciclagem na Indústria do Calçado Português: O caminho de um Sistema Linear para um Sistema Circular

O ano de 2022 surge na indústria como o ano da inovação e recuperação para a crise económica causada pela Covid-19. Sendo a indústria do calçado uma das indústrias que contribui para a economia do país, foi desenvolvida uma pesquisa de modo a compreender o estado atual desta indústria, como pode evoluir de forma mais sustentável e continuar a ser uma mais-valia para o país. A indústria do calçado português tem sido reconhecida externamente pela sua qualidade de produção. Ao mesmo tempo, esta indústria tem vindo a demonstrar a sua preocupação com os impactos socioeconómicos e ambientais, desenvolvendo linhas de produção e produtos cada vez mais sustentáveis, melhorando a imagem do sector. A indústria do calçado portuguesa é conhecida pelo uso de matérias-primas naturais como as peles. Porém, novos materiais são cada vez mais comuns, estando muitos relacionados com economias circulares. Esses materiais surgem a partir do aproveitamento de resíduos gerados pelo próprio processo produtivo ou são materiais de outras indústrias, que são aproveitados para a criação de componentes para o calçado. Para uma melhor compreensão dos tipos de materiais usados na atualidade, iniciou-se este trabalho por uma análise histórica, seguida por uma descrição da evolução de diferentes tendências relacionadas com as fases de produção, tipos de calçado e seus componentes. Desse modo, compreendeu-se as fases do ciclo do produto. A escolha de materiais para um dado tipo de calçado tem um grande impacto no produto final. Foram analisados os materiais usados no fabrico de diferentes tipos de calçado, a gestão de desperdícios durante a produção, o uso de materiais reciclados e o seu papel na divulgação de marcas conhecidas pela sustentabilidade. Da compreensão da cadeia produtiva e das novas tendências foi proposta uma solução prática e sustentável para a indústria do calçado, em uma das fases da economia circular: - a reciclagem. Assim, sugere-se a criação de uma empresa de recolha e tratamento de calçado usado com a finalidade de redução de desperdícios em aterros.The year 2022 comes in industry as the year of innovation and recovery for the economic crisis caused by Covid-19. Since the footwear industry is one of the industries that contributes to the country's economy, a research was developed to understand the current state of this industry, how it can evolve more sustainably and continue to be an added value for the country. The footwear industry has Portuguese been recognized externally for its quality of production. At the same time, this industry has been showing its concern about socioeconomic and environmental impacts by developing increasingly sustainable production lines and products, improving the image of the sector. The Portuguese footwear industry is known for the use of natural raw materials such as fur. However, new materials are increasingly common, with many related to circular economies. These materials arise from the use of waste generated by the production process itself or are materials from other industries, which are used for the creation of components for footwear. For a better understanding of the types of materials used today, this work was initiated by a historical analysis, followed by a description of the evolution of different trends related to the production phases, types of footwear and their components. Thus, the phases of the product cycle were understood. The choice of materials for a given type of footwear has a great impact on the final product. We analyzed the materials used in the manufacture of different types of footwear, the management of waste during production, the use of recycled materials and their role in the dissemination of brands known for sustainability. From the understanding of the production chain and new trends, a practical and sustainable solution was proposed for the footwear industry, in one of the phases of the circular economy: - recycling. Thus, it is suggested the creation of a company for the collection and treatment of used footwear for the purpose of reducing waste in landfills

Hydrogels and cell based therapies in spinal cord injury regeneration

Spinal cord injury (SCI) is a central nervous system- (CNS-) related disorder for which there is yet no successful treatment. Within the past several years, cell-based therapies have been explored for SCI repair, including the use of pluripotent human stem cells, and a number of adult-derived stem and mature cells such as mesenchymal stem cells, olfactory ensheathing cells, and Schwann cells. Although promising, cell transplantation is often overturned by the poor cell survival in the treatment of spinal cord injuries. Alternatively, the therapeutic role of different cells has been used in tissue engineering approaches by engrafting cells with biomaterials. The latter have the advantages of physically mimicking the CNS tissue, while promoting a more permissive environment for cell survival, growth, and differentiation. The roles of both cell- and biomaterial-based therapies as single therapeutic approaches for SCI repair will be discussed in this review. Moreover, as the multifactorial inhibitory environment of a SCI suggests that combinatorial approaches would be more effective, the importance of using biomaterials as cell carriers will be herein highlighted, as well as the recent advances and achievements of these promising tools for neural tissue regeneration.The authors would like to acknowledge the Portuguese Foundation for Science and Technology (Grant no.

332 Predictors and prognostic value of contrast-induced nephropathy in patients undergoing primary angioplasty

PurposeContrast-induced nephropathy (CIN) after coronariography has been associated to increased morbidity and mortality. Patients submitted to primary angioplasty seem to be at higher risk for CIN development, owing in part to hemodynamic status. We sought to determine the prevalence, predictors and prognostic value of CIN occurrence after primary angioplasty.MethodsA total of 141 patients consecutively submitted to primary angioplasty and admitted to our coronary unit were reviewed. CIN was defined as impairment of renal function occurring within 48 hours after administration of contrast media and manifested by an absolute increase in the serum creatinine level of at least 0.5mg/dl or by a relative increase of at least 25% over the baseline value (in the absence of another cause). The primary end points were in-hospital and six-month mortality.ResultsCIN developed in 18.4% of the patients (n=26). Patients with CIN were older (68±13 vs 61±13 years; p<0.05) and more often had diabetes mellitus (38.5% vs 15.7%; p<0.05). Although statistical significance was not reached, there was a trend for higher prevalence of hypertension (61.5% vs 42.6%; p=0.09), female gender (30.8% vs 18.3%; p=0.18) and Killip class higher than one at admission (26.9% vs 16.3%; p=0.1) among patients with CIN. Patients with CIN had an higher mean time from symptoms to reperfusion (304±192 vs 397±206 minutes; p<0.04). By multivariate analysis, independent correlates of CIN were older age (OR=1.04; 95%CI=1.01 − 1.08) and diabetes mellitus (OR=2.99; 95%CI=1.08 − 8.3). Patients with CIN had higher in-hospital (19.2% vs 0.9%; p<0.05) and 6-month mortality (28.6% vs 4.9%; p<0.05).ConclusionsCIN was a frequent complication of primary angioplasty (18.4% of the patients). Independent predictors of CIN after primary angioplasty were older age and diabetes mellitus. Patients with CIN had a worse prognosis, both during in-hospital stay and at 6 months

Exploiting the impact of the secretome of MSCs isolated from different tissue sources on neuronal differentiation and axonal growth

Cell transplantation using Mesenchymal stem cell (MSC) secretome have recently been presented as a possible free-based therapy for CNS related disorders. MSC secretome is rich in several bio-factors that act synergically towards the repair of damaged tissues, thus making it an ideal candidate for regenerative applications. Great effort is currently being made to map the molecules that compose the MSC secretome. Previous proteomic characterization of the secretome (in the form of conditioned media - CM) of MSCs derived from adipose tissue (ASC), bone-marrow (BMSC) and umbilical cord (HUCPVC) was performed by our group, where proteins relevant for neuroprotection, neurogenic, neurodifferentiation, axon guidance and growth functions were identified. Moreover, we have found significant differences among the expression of several molecules, which may indicate that their therapeutic outcome might be distinct. Having this in mind, in the present study, the neuroregulatory potential of ASC, BMSC and HUCPVC CM in promoting neurodifferentiation and axonal outgrowth was tested in vitro, using human telencephalon neuroprogenitor cells and dorsal root ganglion explants, respectively. The CM from the three MSC populations induced neuronal differentiation from human neural progenitor cells, as well as neurite outgrowth from dorsal root ganglion explants. Moreover, all the MSC populations promoted the same extent of neurodifferentiation, while ASC CM demonstrated higher potential in promoting axonal growth.The authors acknowledge the financial support by Premios Santa Casa Neurociencias - Prize Melo e Castro for Spinal Cord ^ Injury Research (MC-17-2013 and MC-04-2017); Portuguese Foundation for Science and Technology (Doctoral fellowships PDE/ BDE/113596/2015 and SFRH/BD/120124/2016 to R.C Assunçao Silva ~ and B.
