Etiologia, Tratamento e Prognóstico da Pericardite Aguda

Introduction: Acute pericarditis is a common inflammatory condition of the pericardium usually assumed to be viral or idiopathic. Despite recent treatment improvements, information is scarce regarding etiology and prognosis. Our aim was to determine the incidence of pericarditis with a known etiology and assess clinical prognostic predictors. Material and Methods: A clinical retrospective analysis of hospitalized patients with acute pericarditis was conducted from 2012 to 2016. Population was characterized according to etiology, clinical presentation, treatment and prognosis. Outcomes of interest, evaluated at one year after hospital discharge, were pericarditis recurrence, hospitalization, constriction and overall mortality. Results: A total of 94 patients were enrolled, median age 46 years (inter-quartile range 32-61), 65% were male. Idiopathic etiology was responsible for 68% of cases. A specific etiology was found in the remaining 32% of patients, being the most frequent autoimmune disease (12%) and malignancy (5%). Idiopathic pericarditis was associated with myopericarditis (p = 0.049) and a known etiology with pericardial effusion (p = 0.001) and cardiac tamponade (p = 0.027). Recurrence of pericarditis was found in 13% of patients. Corticosteroid treatment in patients with an identified etiology was not associated with an increase in recurrence (p = 0.220). Overall 1-year mortality was 9%. A defined etiology was the only independent predictor of mortality at multivariate analysis (OR 40.3; 95% CI 1.9 – 137.2; p = 0.016). Conclusion: Up to one third of hospitalized patients with acute pericarditis have an identified cause of pericarditis and these patients are at increased risk of mortality.Introdução: A pericardite aguda é uma síndrome frequente caracterizada pela inflamação do pericárdio e usualmente atribuído a etiologia viral/idiopática. Apesar dos avanços no tratamento, existe informação limitada em relação a etiologia e prognóstico. O objetivo do nosso trabalho foi identificar a prevalência de pericardite aguda com etiologia especifica e avaliar marcadores clínicos de prognóstico. Material e Métodos: Estudo retrospetivo de doentes hospitalizados por pericardite aguda entre 2012-2016. A população foi caracterizada quanto a etiologia, apresentação clínica, tratamento e prognóstico. Para avaliação de prognóstico foram avaliadas recorrência de pericardite, pericardite constritiva e mortalidade global um ano após alta hospitalar. Resultados: Foram incluídos 94 doentes com idade mediana 46 anos (IIQ 32-61), 65% eram do sexo masculino. A etiologia idiopática foi responsável por 68% dos casos. Etiologia especifica foi identificada em 32% dos doentes, sendo mais frequente doença autoimune (12%) e neoplasia (5%). A pericardite idiopática foi mais associada a miopericardite (p = 0,049), enquanto a etiologia específica se associou a derrame pericárdico (p = 0,001) e a tamponamento pericárdico (p = 0,027). A recorrência de pericardite ocorreu em 13% dos doentes. O tratamento com corticosteroides em doentes com etiologia definida não se associou com aumento de recorrência (p = 0,220). A mortalidade global a um ano foi de 9%. A etiologia definida de pericardite aguda revelou-se o único preditor independente de mortalidade na análise multivariada (OR 40,3; 95% CI 1,9 – 137,2; p = 0,016). Conclusão: Cerca de um terço dos doentes hospitalizados por pericardite aguda têm uma causa específica identificável de pericardite e estes doentes apresentam risco aumentado de mortalidadeinfo:eu-repo/semantics/publishedVersio

Experiential learning through students non-profit organizations: ESTIEM case study

European Students of Industrial Engineering and Management (ESTIEM) is a non-profit organization of Industrial Engineering and Management (IEM) students that was founded in 1990 to support common activities and relations across Europe. Through it, students engage in activities that promote a combination of technological understanding with management skills. Belonging to this type of organization during their graduation time, gives students a plethora of competences that are learned beyond the classes, outside the university walls. These competences are acquired through experiential learning. The objective of this paper is to present ESTIEM creation, evolution and organization. Also, projects participation, events organization and meetings organized are presented as outcomes of ESTIEM students' engagement. This paper intends also to explore how the participation on this type of organization allows students to develop competences and contribute to the IEM student's education. Following the key competencies for lifelong learning recommended by the Council of European Union, some examples of key competences acquired from the experience of the authors are given. Results showed that being member of ESTIEM allows them to develop such competences and they felt better prepared for the labour market.This work has been supported by FCT Fundação para a Ciência e Tecnologia within the R&D Units Project Scope: UIDB/00319/2020 and UIDB/04058/2020

Bleomycin-Induced Lung Injury

Bleomycin is a chemotherapeutic agent commonly used to treat curable diseases such as germinative tumors and Hodgkin’s lymphoma. The major limitation of bleomycin therapy is pulmonary toxicity, which can be life threatening in up to 10% of patients receiving the drug. The mechanism of bleomycin-induced pneumonitis (BIP) involves oxidative damage, relative deficiency of the deactivating enzyme bleomycin hydrolase, genetic susceptibility, and the elaboration of inflammatory cytokines. Ultimately, BIP can progress to lung fibrosis. The diagnosis of BIP is established by the combination of systemic symptoms, radiological and histological findings, and respiratory function tests abnormalities, while other disorders should be excluded. Although the diagnosis and pathophysiology of this disease have been better characterized over the past few years, there is no effective therapy for the disease. In general, the clinical picture is extremely complex. A greater understanding of the BIP pathogenesis may lead to the development of new agents capable of preventing or even treating the injury already present. Physicians who prescribe bleomycin must be aware of the potential pulmonary toxicity, especially in the presence of risk factors. This review will focus on BIP, mainly regarding recent advances and perspectives in diagnosis and treatment
