Gastronomy and Wine in the Alentejo Portuguese Region: Motivation and Satisfaction of Turists from Ăvora
Food and winemaking are a recognized tangible and intangible culturalheritage
of Portugal. From the relationshipbetween these twocomponents, astrategic
product emerged with a considerable potential for tourism industry, which is
notignored bymany of tourism organizations. This chapter intends to analyze food
and winemaking from atourism demand perspective. Particularly, this study
describes visitorsâ profi le, including, their motivations, their knowledgeabout theenological
and gastronomicresourcesand the degreeof satisfaction. A total of 308
questionnaires were collected between February and May of 2012, from the visitors
that visited the historic center of Ăvora (Alentejo-Portugal). Results reveal a visitor
profi le associated with regional cuisine and wine products from Portugal. Moreover,
visitorsâ evidenced a high level of knowledge regarding the Portuguese cuisine and
regional wines; although this not matches with their primary motivation for visit the
city of Ăvora
The Risk of QTc-Interval Prolongation in Breast Cancer Patients Treated with Tamoxifen in Combination with Serotonin Reuptake Inhibitors
Purpose: Antidepressants like the serotonin reuptake inhibitors (SRIs) are often used concomitantly with tamoxifen (e.g. for treatment of depression). This may lead to an additional prolongation of the QTc-interval, with an increased risk of cardiac side effects. Therefore we investigated whether there is a drug-drug interaction between tamoxifen and SRIs resulting in a prolonged QTc-interval. Methods: Electrocardiograms (ECGs) of 100 patients were collected at steady state tamoxifen treatment, with or without concomitant SRI co-medication. QTc-interval was manually measured and calculated using the Fridericia formula. Primary outcome was difference in QTc-interval between tamoxifen monotherapy and tamoxifen concomitantly with an SRI. Results: The mean QTc-interval was 12.4Â ms longer when tamoxifen was given concomitantly with an SRI (95% CI:1.8â23.1Â ms; P = 0.023). Prolongation of the QTc-interval was particularly pronounced for paroxetine (17.2Â ms; 95%CI:1.4â33.0Â ms; P = 0.04), escitalopram (12.5Â ms; 95%CI:4.4â20.6Â ms; P 500Â ms. Conclusions: Concomitant use of tamoxifen and SRIs resulted in a significantly higher mean QTc-interval, which was especially the case for paroxetine, escitalopram and citalopram. When concomitant administration with an SRI is warranted venlafaxine is preferred
Glycosylation defects underlying fetal alcohol spectrum disorder: a novel pathogenetic model: âWhen the wine goes in, strange things come outâ â S.T. Coleridge, The Piccolomini
Fetal alcohol spectrum disorder (FASD) is an umbrella term used to describe the craniofacial dysmorphic features, malformations, and disturbances in growth, neurodevelopment and behavior occurring in individuals prenatally exposed to alcohol. Fetal alcohol syndrome (FAS) represents the severe end of this spectrum. Many pathophysiological mechanisms have hitherto been proposed to account for the disrupted growth and morphogenesis seen in FAS. These include impaired cholesterol-modification of the Sonic hedgehog morphogen, retinoic acid deficiency, lipoperoxidative damage due to alcohol-induced reactive oxygen species combined with reduced antioxidant defences, and malfunctioning cell adhesion molecules. In this report, we propose a completely novel concept regarding the pathogenesis of FAS. Based on our observation that transferrin isoelectric focusing (TIEF) â the most widely used screening tool for congenital disorders of glycosylation (CDG) â was transiently abnormal in a newborn with FAS and a confirmed maternal history of gestational alcohol abuse, we came to believe that FAS exemplifies a congenital disorder of glycosylation secondary to alcohol-inflicted disruption of (N-linked) protein glycosylation. Various pieces of evidence were found in the literature to substantiate this hypothesis. This observation implies, among others, that one might need to consider the possibility of maternal alcohol consumption in newborns with transient glycosylation abnormalities. We also present an integrated pathophysiological model of FAS, which incorporates all existing theories mentioned above as well as our novel concept. This model highlights the pivotal role of disrupted isoprenoid metabolism in the origination of FAS
COVID-19:immunopathology, pathophysiological mechanisms, and treatment options
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to spread globally despite the worldwide implementation of preventive measures to combat the disease. Although most COVID-19 cases are characterised by a mild, self-limiting disease course, a considerable subset of patients develop a more severe condition, varying from pneumonia and acute respiratory distress syndrome (ARDS) to multi-organ failure (MOF). Progression of COVID-19 is thought to occur as a result of a complex interplay between multiple pathophysiological mechanisms, all of which may orchestrate SARS-CoV-2 infection and contribute to organ-specific tissue damage. In this respect, dissecting currently available knowledge of COVID-19 immunopathogenesis is crucially important, not only to improve our understanding of its pathophysiology but also to fuel the rationale of both novel and repurposed treatment modalities. Various immune-mediated pathways during SARS-CoV-2 infection are relevant in this context, which relate to innate immunity, adaptive immunity, and autoimmunity. Pathological findings in tissue specimens of patients with COVID-19 provide valuable information with regard to our understanding of pathophysiology as well as the development of evidence-based treatment regimens. This review provides an updated overview of the main pathological changes observed in COVID-19 within the most commonly affected organ systems, with special emphasis on immunopathology. Current management strategies for COVID-19 include supportive care and the use of repurposed or symptomatic drugs, such as dexamethasone, remdesivir, and anticoagulants. Ultimately, prevention is key to combat COVID-19, and this requires appropriate measures to attenuate its spread and, above all, the development and implementation of effective vaccines.</p
âPlacingâ Space: exploring the socio-spatial impacts of cosmopolitan place-marketing approaches on British migrants in Spain
This article explores the sociospatial underpinnings of cosmopolitan place-marketing narratives and their impacts on British migrants living in Sitges, an affluent tourist town in Spain. Sitgesâ place-marketing suggests that moving there automatically fosters a cosmopolitan identity. For British migrants in Sitges, this was understood to be exemplified through integration into the local community. Yet the vast majority found such integration impossible, not least because this conceptualization of cosmopolitanism overlooked the subjectivity of locals themselves, by whom they were most often rejected. It is argued that this mismatch between British migrantsâ experiences and Sitgesâ cosmopolitan place-marketing occurs because it relies on an understanding of subjective identity as generated locationally, enacted via movement to a specific âtypeâ of place that incorporates particular understandings of space, place, and culture in relation to that identity. This overrides the necessity of relationality, undermining the ideal of reflexive identity-making on which cosmopolitan place-marketing narratives rely
