Rebelo,Ana; Leal,Isabel;
Análise Psicológica , 2007,
Abstract: the aim of this study is to correlate the personality factors and eating behaviour in women diagnosed with morbid obesity. the 48 patients are candidates to bariatric surgery, or that have made it in a near past. the instruments used along this investigation were: sample characterization questionnaire, the personality inventory neo revised and the dutch eating behaviour questionnaire (debq). the results showed the extremely significant statistical value in the dimensions neuroticism and openness, and in the facets impulsiveness, assertiveness, fantasy, feelings, ideas, values, altruism, competence and deliberation; and in the restrained eating and emotional eating dimen-sions. we registered the presence of inadequate feelings with maladaptative coping responses with a low frustration tolerance; characteristics of dominance in the social relations; creativity with the elaboration of fantasies and the presence of situational emotional responses; altruistic behaviour, self-discipline and planning; with an emotional ingestion associated to characteristics of restrained eating. we highlight the importance of psychotherapy during illness process.

Abstract: A ecoendoscopia (EE) é uma das técnicas endoscópicas mais desafiantes e de comprovada validade clínica na actualidade, tendo revolucionado, nas duas últimas décadas, o espectro clínico da gastrenterologia e da patologia oncológica em particular. A aprendizagem desta moderna tecnologia é demorada e laboriosa exigindo conhecimentos específicos sobre a física e artefactos dos ultra-sons, bem como de anatomia humana. Centrada na correla o das características ultra-sonográficas dos diferentes tecidos com as estruturas anatómicas, tem por objectivo conseguir a identifica o estratificada da parede digestiva e dos org os adjacentes, segundo uma perspectiva tomográfica. A necessidade de imprimir delicados movimentos à extremidade do aparelho a par de pormenorizados e imprescindíveis conhecimentos de anatomia ultra-sonográfica, exigem especial habilidade técnica. O papel que ocupa na abordagem das neoplasias do aparelho digestivo ou da patologia benigna e maligna pancreatobiliar, veio confirmar a raz o histórica da sua implementa o, tendo em conta o seu comprovado rendimento clínico. Ao permitir uma minuciosa observa o ultra-sonográfica das diferentes camadas da parede digestiva, com demonstrada correspondência histológica, acrescentou uma nova metodologia e capacidade na investiga o complementar sem se sobrepor a outros métodos de imagem, como a tomografia computorizada ou a ressonancia magnética nuclear. A possibilidade de aspira o ou injec o com agulha fina de estruturas intra e extraluminais, sob orienta o da EE em tempo real, tem vindo a ampliar as suas potencialidades, quer no ambito do diagnóstico quer das aplica es terapêuticas. O desenvolvimento progressivo desta técnica, com capacidades crescentes, levou a que fosse aplicada, também, ao estudo de patologia em órg os extra-digestivos, como é o caso do pulm o mediastino e, mais recentemente, de org os genitais externos. Esta primeira parte, de uma sequência de artigos de revis o sobre ecoendoscopia, pretende abordar os aspectos relacionados com o equipamento utilizado, as principais indica es e os achados ultra-sonográficos das altera es da parede gastrointestinal. Endoscopic ultrasonography represents one of the most challenging endoscopic techniques and has a proven clinical value. In the last two decades it has revolutionized the clinical spectrum of gastroenterology and oncologic pathology in particular. The learning curve is very long and laborious, requiring knowledge of the ultrasound physics and of human anatomy. It permits a correlation between tissues with different ultrasonographic ch

Abstract: montreal classification (mc) succeeded vienna classification (vc) in the characterization of patients with crohn′s disease (cd). in order to evaluate the differences and potential advantages of the first regarding the last one and validate the mc through the longitudinal analysis of the phenotypic variation of this population, 122 crohn′s patients were retrospectively analyzed and classified according to both classifications. the evolution of both subgroups and the need for surgery was analysed. results showed that mc reclassified 6 patients in the criteria age at diagnosis (a), 4 in the criteria location (l) and 18 in the criteria behaviour (b). the disease location (l) remained stable. the behaviour (b) by the vc classification changed at 3 and 5 years. 41,8% of patients underwent major surgery. a higher association between the need for surgery and the group b3 of mc was identified. there were no statistically significant differences between the survival curves and sex, smoking and age at diagnosis. conclusion: the mc is more sensitive in the phenotypic evaluation of behaviour of cd, especially after exclusion of perianal disease from the category penetrating disease. the classification of cd by phenotypic pattern could possibly, in future, be applied to predict its natural history.

Abstract: INTRODU O: A suspeita de Doen a de Crohn (DC) é uma indica o frequente para a realiza o de enteroscopia por cápsula (EC). No entanto, os achados endoscópicos s o inespecíficos e n o existem critérios validados ou um gold-standard para o diagnóstico da doen a. O Score de Lewis (SL) valoriza a presen a de edema vilositário, úlceras e estenoses, permitindo classificar o nível de actividade inflamatória. OBJECTIVOS: Avaliar a utilidade do SL na prática clínica, enquanto contributo para o diagnóstico da DC. MéTODOS: Foram incluídos trinta doentes consecutivos com suspeita de DC, submetidos a EC e com um follow-upmínimo de seis meses. A actividade inflamatória foi classificada em três níveis: n o significativa (score < 135); ligeira (135 ≤ score ≤ 790) ou moderada a severa (score > 790). RESULTADOS: Foi estabelecido o diagnóstico de DC em 10 doentes (33%). A presen a de actividade inflamatória significativa (score ≥ 135), apresentou um Valor Preditivo Positivo (VPP) = 75%, Valor Preditivo Negativo (VPN) = 94%, Sensibilidade (S) = 90% e Especificidade (E) = 85% para o diagnóstico de DC. CONCLUS ES: A utiliza o do SL parece ser um indicador útil na suspeita de DC, permitindo aumentar a objectividade da interpreta o dos achados endoscópicos e apresentando uma boa correla o com o diagnóstico estabelecido durante o follow-up.

Abstract: A Classifica o de Montreal (CM) sucedeu à de Viena (CV) na caracteriza o dos doentes com Doen a de Crohn (DC). Com o objectivo de avaliar as diferen as e potenciais vantagens da primeira em rela o à última e validar a CM através da análise longitudinal da varia o fenotípica desta popula o, analisaram-se retrospectivamente 122 doentes com DC classificados segundo as CV e CM. Avaliou-se a evolu o dos subgrupos e a necessidade de cirurgia. Nos resultados verificou-se que a CM reclassificou 6 doentes no critério idade de diagnóstico (A), 4 no critério localiza o (L) e 18 no critério comportamento (B). A localiza o (L) da doen a permaneceu estável. O comportamento (B) pela CV modificou-se aos 3 e 5 anos. Foram submetidos a cirurgia major 41,8% dos doentes. Identificou-se uma maior associa o entre a necessidade de cirurgia e o grupo B3 da CM. N o se verificaram diferen as estatisticamente significativas entre as curvas de sobrevivência e as variáveis sexo, tabaco e idade de diagnóstico. CONCLUS O: A CM é mais sensível na avalia o fenotípica do comportamento da doen a, principalmente após a exclus o da doen a perianal da categoria doen a penetrante. A classifica o da DC por padr o fenotípico poderá eventualmente, no futuro, ser aplicada para predizer a sua história natural.

Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.72025
Abstract: This paper develops a comparative overview of SEA in Kenya, Tanzania and South Africa regarding legal, institutional and procedural perspectives, in order to assess their effectiveness and unveil main constrains. It is clear from this brief review that SEA is a tool of environmental governance that is of growing importance in East and Southern Africa. With regards to the institutional and legal framework, both Kenya and Tanzania have formal provisions for SEA, but no specific legislation. The main constrains on SEA effectiveness are related to the lack of a clear mandate and institutional framework, guidelines for procedures and public participation. As this analysis and case studies from the three countries examined here reveal, Kenya, Tanzania, and South Africa have expanded their use of SEA as a preventive mechanism for environmental policy and to enhance the efficiency of strategic decisions. While each of these countries has made great strides in developing the SEA process and integrating it into their decision-making processes, much work remains to be done. Ongoing refinement to the SEA process, both within this region and elsewhere in the world, will mean that this important tool integrates sustainable environmental management principles and practices into policies, plans, and programmes and the decision-making process.
Comparative Evaluation of the EIA Systems in Kenya, Tanzania, Mozambique, South Africa, Angola, and the European Union  [PDF]
Cristina Rebelo, José Guerreiro
Journal of Environmental Protection (JEP) , 2017, DOI: 10.4236/jep.2017.85040
Abstract: This article provides a comparative overview of environmental impact assessment (EIA) in Mozambique, Tanzania, Kenya, South Africa, Angola, and the European Union (EU). EIA “systemic measure” and “foundation measure” criteria are used to evaluate and compare the performance of each system. In contrast to the EU, EIA must be carried out by registered experts in the African countries. In Tanzania, Mozambique and South Africa public consultation is mandatory during scoping. In Kenya and Tanzania the EIA study should contain measures to prevent health hazards, to ensure employee safety, and for emergency management. EIA system monitoring is required in Kenya, Tanzania, Mozambique, and in the EU, but not in South Africa and Angola. Financial issues, insufficient qualified personnel, and an increasing number of EIA applications undermine the capacity of competent authorities to adequately monitor these EIA systems. Consequently, training programmes increase effectiveness of EIA implementation is a common request. The African countries reviewed here have adopted EIA and integrated EIA systems into public policy despite the constraints they face. As they continue to gain experience in EIA and to revise their EIA systems, they are moving towards a more flexible system with greater public involvement and robust arrangements and practices.
