    Music has become a dominant and popularised form of culture in the modern world, produced and reproduced by the masses. It seems that the idea of continuous separation of the ‘human’ with the ‘nonhuman’ created a deep gap regarding the conceptualization of organic and harmonious practices for sustainable development of the world’s economic, cultural and social spheres. With this individualistic perspective, the idea of community and the connection between the outside world and humans have fallen into oblivion. Music culture and the music industries, powered by a massive technological and globalised process, have allowed an international travelling of sound with traits and characteristics of different cultures, rituals and ways of making music. Music is a way of connecting with the world. Specifically, the jazz musical genre approaches change in musical and performative practices while preserving its connection to its roots, tradition and rituals. It distinguishes itself from other musical genres through its instrumental characteristics, musical dialogues, and intrinsic traits that refer to its history and sociocultural influence. Aiming to reconcile the environment and civilisation, together with the intersection of the nonhuman and human world, the physical and the cultural spheres all mediated by sound composition, this dissertation explores the musical genre of jazz and its live performances in a given surrounding. Following an extensive literature review, this work delves into the fundamental aspects of sound, music, audience, performance and performativity. It travels through sensations and relationships integrated into the ecological performative system. To question the way the spirit and sensation of a place, through an ecological approach affects the performance of a cultural product such as live jazz, and how this influences the performance/performers and audiences, the work approaches three main blocks: the social cooperation in music and its instrumental relationship, the intersection between actor and audience and the embeddedness of the performance in a specific environment.No mundo moderno, a música tem vindo a tornar-se numa forma de cultura dominante e popularizada, produzida e reproduzida pelas massas. Parecer que a ideia de uma separação contínua do humano em relação ao ‘não-humano’ criou um espaçamento profundo relativamente à conceptualização de práticas orgânicas e harmoniosas para um desenvolvimento sustentável das esferas económicas, culturais e sociais do nosso mundo. De acordo com uma perspetiva individualista, parece que a ideia de comunidade e elo entre o mundo exterior e o homem caíram no esquecimento. A cultura e as indústrias musicais, impulsionadas por um grande processo tecnológico global, têm permitido uma viagem internacional de som com traços e características de diferentes culturas, rituais e práticas de conceção musical. A música é uma forma de ligação com o mundo. Especificamente, o género musical jazz aborda a mudança nas práticas musicais e performativas, preservando uma conexão com as suas raízes, tradições e rituais. Distingue-se de outros géneros musicais através das suas características instrumentais, diálogos musicais e traços intrínsecos que se referem à sua história e influência sociocultural. Visando uma reconciliação do meio ambiente e da civilização, juntamente com a intersecção do mundo não humano e humano, as esferas física e cultural por intermédio da composição sonora, esta dissertação explora o género musical jazz e suas performances ao vivo num determinado ambiente. Após uma extensa revisão da literária, este trabalho explora os aspetos fundamentais da música, espaço, público, performance e performatividade. O trabalho percorre as sensações e relações que se integram no sistema performativo ecológico. De forma a questionar como o espírito e a sensação de um lugar, por meio de uma abordagem ecológica, afetam a performance de um produto cultural como o jazz ao vivo, e ainda, como isso influencia a performance/atores e o público, o trabalho aborda três blocos principais: a cooperação social na música e sua relação instrumental, a interseção entre ator-performance-público e a inserção da performance num ambiente específico

    Imagiological Diagnosis of Gastrointestinal Diseases – Diagnostic Criteria of Hepatocellular Carcinoma

    Get PDF
    AbstractHepatocellular carcinoma (HCC) is one of the leading causes of neoplastic morbidity and mortality worldwide, and despite recent treatment advances, the prognosis remains dismal, with a 5-year mortality rate of 85%.The surveillance and timely diagnosis is therefore of crucial importance in order to improve survival rates and alleviate the health burden imposed by the HCC.Previously, HCC diagnosis warranted liver biopsy, an invasive process with limited diagnostic accuracy. In the past 15 years, HCC diagnosis based solely on imaging criteria was accepted by all the major national and international guidelines, and is now widely employed across the globe.Current European guidelines for the HCC diagnosis support the use of both dynamic contrasted computer tomography as well as magnetic resonance imaging for the non-invasive diagnosis of HCC for nodules >1cm in a cirrhotic liver. The non-invasive diagnosis of HCC depends on radiological hallmarks, such as homogeneous contrast uptake during the arterial phase and wash-out during the venous and late phases, but while such tumoral behaviour is frequent in nodules >2cm, high-end equipment and superior expertise is often needed for the correct diagnosis of early HCC.Nevertheless, the accuracy of imaging techniques for the diagnosis of HCC is permanently improving, and supports the progressively reduced need for liver biopsy during liver nodule workout in a cirrhotic liver

    Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Arquitetura apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.O convento de Chelas, situa-se no Vale de Chelas na zona oriental de Lisboa. É uma das mais antigas casas monásticas da cidade, tendo sido testemunho de variadas ocupações e usos diferenciados que imprimiram um caráter mutante ao longo dos anos. Encontra-se atualmente ocupado pelo Arquivo Geral do Exército, que mantém preservadas as suas dependências conventuais e industriais. O grande estado de degradação do Convento e o panorama de abandono do meio urbano, cria uma janela de oportunidade para reflexão acerca da sua reabilitação e perspetiva futura. Insere-se na discussão da importância da preservação do património religioso e industrial que se encontra ao longo do Vale de Chelas. É nesse sentido que se procura entender o papel que o Convento de Chelas e a sua cerca terão no futuro do Vale e a dinâmica que podem imprimir na sua envolvente. Assim, o objetivo do trabalho passa por analisar o objeto de estudo num enquadramento mais alargado e profundo, recorrendo a uma metodologia baseada na experiência humana no lugar, incidindo na individualidade e especificidade do Convento. Este conjunto conventual apresenta uma forte pretensão de se manter como parte integrante da paisagem do Vale que merece ser preservada. É nesse sentido, que se apresenta aqui, a proposta para uma intervenção fundamentada por uma leitura fenomenológica, que visa restituir um futuro a este conjunto conventual.ABSTRACT: The Convent of Chelas is situated in the Chelas Valley in eastern Lisbon. It is one of the oldest monastics housed of the city, it has witnessed numerous occupations and different uses that gave a changing character throughout the years. It is currently occupied by the General Archives of the Army, maintaining its convent and industrial premises. The great state of degradation of the convent and the panorama of neglection of the urban environment characterized by void and ruins, gives a window opportunity to reflect on its rehabilitation and future perspective. It is part of the discussion on the importance of the preservation of the religious and industrial heritage that exists along the Chelas Valley. This is how one tries to understand the role that the Convent of Chelas and its fence will have in the valley and the consequent dynamics that will print in its surrounding. Thus, the objective of the project is to analyse the object of study in a broader and deeper context, using a methodology base on human experience in site, with focus on the individuality and specificity of the Convent. The Convent complex present a strong will to remain an integral part of the valley landscape that deserves to be preserved. Therefore, it is presented here, the proposal for an intervention based on a phenomenological reading, which aims to restore the future of this Convent.N/

    Get PDF
    Mantle cell lymphoma (MCL) of the colon is a rare entity, usually presenting as lymphomatous polyposis. We report the case of a 43-year-old male with an unusual colonic MCL in the form of a single exophytic and ulcerous lesion with necrotic areas associated with an ileo-cecal intussusception. The endoscopic appearance suggested adenocarcinoma. However, the diagnosis was made by histology and immunohistochemistry studies of the endoscopic biopsies

    Background: Bariatric surgery (BS) is one of the most effective approaches to weight loss. Performing esophagogastroduodenoscopy (EGD) prior to BS is controversial but allows the detection and treatment of mucosal lesions that may affect surgical decision and type of surgery. Aim: The aim of this study was to identify the frequency of gastric lesions and Helicobacter pylori (Hp) infection in a group of asymptomatic patients on the waiting list for BS. Methods: This is a retrospective descriptive study including patients undergoing EGD before BS. Results: A total of 360 patients were included with a mean age of 42.1 ± 10.8 years, 319 (88.6%) were females, with a mean body mass index of 42.8 ± 5.44 kg/m2. Regarding endoscopic findings, 25.6% presented no endoscopic lesions, 61.6% presented hyperemic gastropathy, 11.4% erosive gastropathy, 1.1% gastric polyp, and 0.3% gastric ulcer. Histologically, no changes were observed in 20.8% of the patients, 239 (66.4%) presented with superficial gastritis, 11.7% (n = 42) had chronic atrophic gastritis and intestinal metaplasia (n = 34 in the antrum, n = 1 in the body, and n = 7 in both the antrum and the body), and 1.7% (n = 6) had low-grade dysplasia. Hp was positive in 251 (69.7%) patients. We found that patients with metaplasia or dysplasia were more frequently submitted to surgical techniques that did not exclude the stomach (55.8 vs. 16.4%, p < 0.001). Conclusion: EGD with histological analysis plays an important role in the pre-surgical evaluation in BS, with a high rate of pathological findings in asymptomatic patients. These findings may have an impact on the long-term management and outcomes of these patients.(undefined

    AIM To evaluate mucosal healing in patients with small bowel plus colonic Crohn's disease (CD) with a single non-invasive examination, by using PillCam COLON 2 (PCC2). METHODS Patients with non-stricturing nonpenetrating small bowel plus colonic CD in sustained corticosteroid-free remission were included. At diagnosis, patients had undergone ileocolonoscopy to identify active CD lesions, such as ulcers and erosions, and small bowel capsule endoscopy to assess the Lewis Score (LS). After = 1 year of follow-up, patients underwent entire gastrointestinal tract evaluation with PCC2. The primary endpoint was assessment of CD mucosal healing, defined as no active colonic CD lesions and LS < 135. RESULTS Twelve patients were included (7 male; mean age: 32 years), and mean follow-up was 38 mo. The majority of patients (83.3%) received immunosuppressive therapy. Three patients (25%) achieved mucosal healing in both the small bowel and the colon, while disease activity was limited to either the small bowel or the colon in 5 patients (42%). It was possible to observe the entire gastrointestinal tract in 10 of the 12 patients (83%) who underwent PCC2. CONCLUSION Only three patients in sustained corticosteroid-free clinical remission achieved mucosal healing in both the small bowel and the colon, highlighting the limitations of clinical assessment when stratifying disease activity, and the need for pan-enteric endoscopy to guide therapeutic modification

    Introduction: Helicobacter pylori eradication has become increasingly difficult as resistances to several antibiotics develop. We aimed to compare Helicobacter pylori eradication rates between triple therapy and sequential therapy in a naive Portuguese population. Material and Methods: Prospective randomized trial including consecutive patients referred for first-line Helicobacter pylori eradication treatment. Exclusion criteria: previous gastric surgery/neoplasia, pregnancy/lactancy, allergy to any of the drugs. The compared eradication regimens were triple therapy (pantoprazol, amoxicillin and clarithromycin 12/12 hours, 14 days) and sequential therapy (pantoprazol 12/12 hours for 10 days, amoxicillin 12/12 hours for days 1-5 and clarithromycin plus metronidazol 12/12 hours during days 6 -10). Eradication success was confirmed with urea breath test. Statistical analysis was performed with SPSS v21.0 and a p-value < 0.05 was considered statistically significant. Results: Included 60 patients, 39 (65%) female with mean age 52 years (SD +/- 14.3). Treatment groups were homogeneous for gender, age, indication for treatment and smoking status. No statistical differences were encountered between sequential and triple therapy eradication rates (86.2% vs 77.4%, p = 0.379), global eradication rate was 82%. Tobacco consumption was associated with a significantly lower eradication success (54.5 vs 87.8%, p = 0.022). Discussion: In this randomized controlled trial in a naive Portuguese population, we found a satisfactory global Helicobacter pylori eradication rate of 82%, with no statistical differences observed in the efficacy of the treatment between triple and sequential regimens. Conclusion: These results support the use of either therapy for the first-line eradication of Helicobacter pylori.info:eu-repo/semantics/publishedVersio

    Background/Aims: Identifying predictors of endoscopic recurrence (ER) has become very important to guide the decision of postoperative strategy. This study aimed to determine the rate of endoscopic recurrence until 12 months after ileocolic resection for Crohn disease (CD) in a cohort and identify its possible predictors. Materials and Methods: We conducted a retrospective single-center study that included patients with CD who underwent ileocolic resection between 2003 and 2014. ER was defined according to the Rutgeerts' score, defined as i2, i3, or i4 at ileocolonoscopy that was performed 6-12 months after surgery. The patients were classified into two groups according to the Rutgeerts' score: non-ER (Rutgeerts i0/i1) and ER (Rutgeerts >= i2). Multivariate logistic regression analysis was performed, including significant variables on univariable analysis, to identify ER predictors. Results: Forty-two patients were included. The mean period of the first postoperative colonoscopy was 9 months, and ER was observed in 25 patients (59.5%). The perianal disease and shorter duration of CD were the only ER predictors (p=0.024; OR, 8.36; 95% CI, 1.329-52.642 and p=0.039; OR, 0.965; 95% CI, 0.933-0.998, respectively). Conclusion: Endoscopic recurrence affects almost two-thirds of patients with CD after ileocolic resection, with perianal involvement and a shorter duration of disease being significant risk factors. These factors may indicate a more aggressive disease associated with rapid progression and support the need of intensive early treatment to improve patients' outcomes.info:eu-repo/semantics/publishedVersio

    Mucosal healing in ulcerative colitis – when zero is better

    Background and aims: Extensive evidence has underlined the importance of mucosal healing as a treatment aim for ulcerative colitis (UC). We aimed to assess differences in the incidence of clinical relapse at 12 months between UC patients with Mayo endoscopic scores (MES) 0 and 1. Methods: This retrospective study included consecutive patients in corticosteroid-free remission between 2008 and 2013 and with follow-up of at least 1 year, with MES 0 or 1 in complete colonoscopy. Clinical relapse was defined as need for induction treatment, treatment escalation, hospitalization or surgery. A p value < 0.05 was considered statistically significant. Results: The study included 138 patients, 72 (52.2%) female, with mean age of 49 (+/- 14) years. Inflammatory activity was classified as MES 0 in 61 (44.2%) patients and MES 1 in 77 (55.8%) patients. Clinical relapse during follow-up was significantly more frequent in patients with MES 1 than MES 0 (27.3 vs 11.5%, p = 0.022), and in the multivariate analysis MES 1 was the only factor significantly associated with an increased risk of relapse (odds ratio 2.89, 95% confidence interval 1.14-7.36, p = 0.026). This association was encountered in the subgroup of patients with left-sided/ extensive colitis (29.7 vs 11.1%, p = 0.049), but not proctitis (25.0 vs 12.0%, p = 0.202). Conclusions: In patients with UC in corticosteroid-free remission, particularly those with left-sided colitis or extensive colitis, MES 1 was significantly associated with a 3-fold increased risk of relapse compared with endoscopic MES 0. Our results support the use of endoscopic MES 0 as the most suitable treatment endpoint to define mucosal healing in patients with UC.info:eu-repo/semantics/publishedVersio
