Population wide testing pooling strategy for SARS-CoV-2 detection using saliva
Esteves, Eduardo; Mendes, Ana Karina; Barros, Marlene; Figueiredo, Cátia; Andrade, Joana; Capelo, Joana; Novais, António; Rebelo, Carla; Soares, RitaSARS-CoV-2 pandemic has forced frequent testing of populations. It is necessary to identify the most cost-effective strategies for the detection of COVID-19 outbreaks. Nasopharyngeal samples have been used for SARS-CoV-2 detection but require a healthcare professional to collect the sample and cause discomfort and pain to the individual. Saliva has been suggested as an appropriate fluid for the diagnosis of COV...
O ensino da Medicina Nuclear durante a pandemia de COVID-19: reflexão após um a...
Costa, Pedro Silva; Vieira, Domingos Manuel da Silva; Lemos, Joana Cristina da Costa; Costa, Pedro; Lemos, JoanaA Medicina Nuclear é uma especialidade médica na qual a formação de base dos Técnicos Superiores de Diagnóstico e Terapêutica está, actualmente, integrada na Licenciatura em Imagem Médica e Radioterapia. Devido à sua vertente tecnológica, mas também ao dinamismo do conhecimento neste domínio científico e à actualização constante das ferramentas disponíveis para uso em ambiente clínico e biomédico, o investiment...
Management of COVID-19 pandemic in Nuclear Medicine departments: A contribute f...
Costa, Pedro; Lemos, Joana; Vieira, Domingos; Arantes, N.Considering the infection with the new Coronavirus (SARS-CoV-2), which may evolve into CoronaVirus Disease 2019 (COVID-19), and the pandemic that is active, standards, guidelines and recommendations have been issued by diverse entities at the governmental, professional and scientific levels.
O potencial da filosofia Lean na gestão de Departamentos de Medicina Nuclear: a...
Lemos, Joana; Vieira, Domingos; Arantes, Nuno; Costa, PedroA Medicina Nuclear (MN) está em constante evolução, desafiando os profissionais a dominar conhecimentos e competências modernas e dinâmicas. A gestão diária em MN é complexa, implicando a interligação de múltiplos aspetos como: doentes, profissionais de saúde, informação, procedimentos, tempo e radiação. Nesse contexto, tem vindo a ser proposto o recurso a filosofias de gestão, como a filosofia Lean, para apoio...
Opening minds to Lean management in Nuclear Medicine
Lemos, Joana; Vieira, Domingos; Arantes, N.; Costa, PedroNuclear Medicine (NM) is in constant technological evolution, challenging often professionals to be up to most recent standards and practices. In this sense, teaching NM should not be limited on the transmission of technical and scientific knowledge but also on opening minds to, for example, different management philosophies. Therefore, Nuclear Medicine students should be capable to change behaviours/practices ...
Desenvolvimento e aplicação de modelos biológicos para estudo de efeitos da rad...
Lemos, Joana; Vieira, Domingos; Costa, PedroCom o crescente uso médico das radiações ionizantes, tanto ao nível dos meios complementares de diagnóstico (ex: Medicina Nuclear e Radiologia), como ao nível terapêutico (ex: Radioterapia), as preocupações inerentes ao aumento da exposição da população a este tipo de radiações têm aumentado. Apesar dessas preocupações, a literatura carece ainda de evidência científica suficiente para esclarecer a relação entre...
Single Low-Dose Ionizing Radiation Induces Genotoxicity in Adult Zebrafish and ...
Lemos, Joana; Neuparth, T.; Trigo, M.; Costa, Pedro; Vieira, Domingos; Cunha, L.; Ponte, F.; Costa, P. S.; Metello, Luís; Carvalho, A. P.This study investigated to what extent a single exposure to low doses of ionizing radiation can induce genotoxic damage in irradiated adult zebrafish (Danio rerio) and its non-irradiated F1 progeny. Four groups of adult zebrafish were irradiated with a single dose of X-rays at 0 (control), 100, 500 and 1000 mGy, respectively, and couples of each group were allowed to reproduce following irradiation. Blood of pa...
Lipid peroxidation and antioxidant responses in zebrafish models after exposure...
Lemos, Joana; Guimarães, Laura; Vasconcelos, Vítor; Ponte, Fernanda; Costa, Paulo; Carvalho, António Paulo; Metello, Luís F.OBJECTIVES: The use of zebrafish – Danio rerio – has grown considerably, demonstrating the increasing interest to use this model in biomedical research, essentially because of the level of homology shared with the human genome, complemented by an easy and reasonably affordable practical side. This work aims to study the radiobiological effects of exposure to low doses of ionizing radiation.
Assessing radiobiological effects of low doses of ionizing radiation on zebrafi...
Lemos, Joana; Campos, Alexandre; Carneiro, Mariana; Ribeiro, Tiago; Ponte, Fernanda; Costa, Paulo; Cunha, Lídia; Carvalho, António PauloIntroduction: This work relates with the application of zebrafish - Danio rerio - to the study of radiobiological effects of low doses of ionizing radiation. In recent years, the use of zebrafish has grown considerably, pointing more and more as a very interesting model in biomedical research, essentially because of the level of homology shared with the human genome, complemented by an easy and reasonably affor...
Antioxidant and oxidative stress responses in zebrafish brain after exposure to...
Lemos, Joana; Guimarães, Laura; Vasconcelos, Vítor; Ponte, Fernanda; Costa, Paulo; Metello, Luís F.; Carvalho, António PauloIntroduction: The use of zebrafish – Danio rerio – has grown considerably, demonstrating the increasing interest to use this model in biomedical research. This is essentially due to the level of homology shared with the human genome, complemented by an easy and reasonably affordable practical side. Hence, this work investigated radiobiological effects of exposure to low doses of ionizing radiation in zebrafish.
