    Arritmias Cardíacas no Contexto da Pandemia da COVID-19: Uma Revisão Integrativa da Literatura / Cardiac Arrhythmias in the COVID-19 Pandemic Context: An Integrative Literature Review

    Get PDF
    A COVID-19 é uma doença oriunda do contágio pelo vírus Sars-CoV-2, um membro da família Coronaviridae, responsável por cerca de 3,3 milhões de óbitos em todo o mundo desde o início das notificações da doença, em dezembro de 2019. Uma das manifestações frequentes no contexto da COVID-19 são as arritmias, que podem ocorrer devido ao efeito inflamatório em resposta ao vírus, hipóxia, desregulação metabólica e/ou pelo dano direto ao tecido cardíaco. Até o momento não se tem, na literatura especializada, terapia farmacológica específica para o tratamento de arritmias nesses casos. Essa revisão tem por objetivo analisar os casos de pacientes infectados pelo Sars-Cov-2 que desenvolveram arritmias cardíacas e as principais manifestações apresentadas por eles, além de relacionar fatores como idade, sexo, histórico patológico pregresso a doença e terapia farmacológica utilizada contra o COVID-19. Foi realizada uma revisão integrativa de literatura sobre as arritmias cardíacas no contexto da atual pandemia, buscando disseminar e entender tal temática. Foram utilizados as plataformas Pubmed, Science Direct e banco de dados da BVS (Biblioteca Virtual de Saúde) com os descritores “cardiac arrhythmias” e COVID-19”, e  LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) com os seguintes descritores, “coração” e “COVID-19”, obtendo, após seleção, um total de 78 artigos-estudos. Dessa forma, dos estudos analisados, 45 casos diferentes foram compilados, seguindo os fatores previamente citados no objetivo. A idade média dos pacientes foi de aproximadamente 59 anos, com predomínio do sexo masculino. As comorbidades encontradas mais frequentes foram a hipertensão e a diabetes e o tratamento principal foi o uso de hidroxicloroquina/cloroquina. Ademais, constatou-se as seguintes arritmias nos casos analisados: taquicardia (47 casos), bradicardia (24 casos), intervalo QT/QTc longo (11 casos) e extrasístoles (7 casos). Assim, observou-se que as manifestações clínicas relacionadas a COVID-19 podem afetar o sistema cardiovascular e/ou agravar uma possível condição cardiovascular pré-existente

    Objective: Negative symptoms are currently viewed as having a 2-dimensional structure, with factors reflecting diminished expression (EXP) and motivation and pleasure (MAP). However, several factor-analytic studies suggest that the consensus around a 2-dimensional model is premature. The current study investigated and cross-culturally validated the factorial structure of BNSS-rated negative symptoms across a range of cultures and languages. Method: Participants included individuals diagnosed with a psychotic disorder who had been rated on the Brief Negative Symptom Scale (BNSS) from 5 cross-cultural samples, with a total N = 1691. First, exploratory factor analysis was used to extract up to 6 factors from the data. Next, confirmatory factor analysis evaluated the fit of 5 models: (1) a 1-factor model, 2) a 2-factor model with factors of MAP and EXP, 3) a 3-factor model with inner world, external, and alogia factors; 4) a 5-factor model with separate factors for blunted affect, alogia, anhedonia, avolition, and asociality, and 5) a hierarchical model with 2 second-order factors reflecting EXP and MAP, as well as 5 first-order factors reflecting the 5 aforementioned domains. Results: Models with 4 factors or less were mediocre fits to the data. The 5-factor, 6-factor, and the hierarchical second-order 5-factor models provided excellent fit with an edge to the 5-factor model. The 5-factor structure demonstrated invariance across study samples. Conclusions: Findings support the validity of the 5-factor structure of BNSS-rated negative symptoms across diverse cultures and languages. These findings have important implications for the diagnosis, assessment, and treatment of negative symptoms

    Objective To compare colorectal cancer (CRC) incidences in carriers of pathogenic variants of the MMR genes in the PLSD and IMRC cohorts, of which only the former included mandatory colonoscopy surveillance for all participants. Methods CRC incidences were calculated in an intervention group comprising a cohort of confirmed carriers of pathogenic or likely pathogenic variants in mismatch repair genes (path_MMR) followed prospectively by the Prospective Lynch Syndrome Database (PLSD). All had colonoscopy surveillance, with polypectomy when polyps were identified. Comparison was made with a retrospective cohort reported by the International Mismatch Repair Consortium (IMRC). This comprised confirmed and inferred path_MMR carriers who were first- or second-degree relatives of Lynch syndrome probands. Results In the PLSD, 8,153 subjects had follow-up colonoscopy surveillance for a total of 67,604 years and 578 carriers had CRC diagnosed. Average cumulative incidences of CRC in path_MLH1 carriers at 70 years of age were 52% in males and 41% in females; for path_MSH2 50% and 39%; for path_MSH6 13% and 17% and for path_PMS2 11% and 8%. In contrast, in the IMRC cohort, corresponding cumulative incidences were 40% and 27%; 34% and 23%; 16% and 8% and 7% and 6%. Comparing just the European carriers in the two series gave similar findings. Numbers in the PLSD series did not allow comparisons of carriers from other continents separately. Cumulative incidences at 25 years were < 1% in all retrospective groups. Conclusions Prospectively observed CRC incidences (PLSD) in path_MLH1 and path_MSH2 carriers undergoing colonoscopy surveillance and polypectomy were higher than in the retrospective (IMRC) series, and were not reduced in path_MSH6 carriers. These findings were the opposite to those expected. CRC point incidence before 50 years of age was reduced in path_PMS2 carriers subjected to colonoscopy, but not significantly so

    Dominantly inherited micro-satellite instable cancer – the four Lynch syndromes - an EHTG, PLSD position statement

    Get PDF
    The recognition of dominantly inherited micro-satellite instable (MSI) cancers caused by pathogenic variants in one of the four mismatch repair (MMR) genes MSH2, MLH1, MSH6 and PMS2 has modified our understanding of carcinogenesis. Inherited loss of function variants in each of these MMR genes cause four dominantly inherited cancer syndromes with different penetrance and expressivities: the four Lynch syndromes. No person has an “average sex “or a pathogenic variant in an “average Lynch syndrome gene” and results that are not stratified by gene and sex will be valid for no one. Carcinogenesis may be a linear process from increased cellular division to localized cancer to metastasis. In addition, in the Lynch syndromes (LS) we now recognize a dynamic balance between two stochastic processes: MSI producing abnormal cells, and the host’s adaptive immune system’s ability to remove them. The latter may explain why colonoscopy surveillance does not reduce the incidence of colorectal cancer in LS, while it may improve the prognosis. Most early onset colon, endometrial and ovarian cancers in LS are now cured and most cancer related deaths are after subsequent cancers in other organs. Aspirin reduces the incidence of colorectal and other cancers in LS. Immunotherapy increases the host immune system’s capability to destroy MSI cancers. Colonoscopy surveillance, aspirin prevention and immunotherapy represent major steps forward in personalized precision medicine to prevent and cure inherited MSI cancer

    Trabalho de Conclusão de Curso, apresentado para obtenção do grau de Bacharel no curso de Odontologia da Universidade do Extremo Sul Catarinense, UNESC.Introdução. O exame radiográfico pode ser essencial para o diagnóstico das doenças bucais assintomáticas e na confirmação de sinais e sintomas clínicos. Buscou-se verificar o perfil epidemiológico dos pacientes, do Sistema Único de Saúde do município de Criciúma/SC, submetidos a exames radiográficos intra-bucais, realizados por uma clínica de radiologia odontológica particular. Métodos: Foi realizado um estudo transversal, descritivo, com abordagem quantitativa, de uma amostra de 576 radiografias intra-bucais, distribuídas em 290 laudos, no período de um ano. Os pacientes foram classificados quanto à idade e gênero. As informações dos laudos foram divididas em dois grupos: achados radiográficos e lesões patológicas. Através de testes estatísticos, os dados foram cruzados com idade e gênero. Resultados: Quanto às lesões, a cárie (61,5%) foi a doença mais frequente e, entre os achados radiográficos, cristas alveolares normais(43,7%). A doença cárie foi estatisticamente significante (p=0,001) com o gênero feminino (83,3%). No grupo de achados radiográficos, as cristas alveolares normais, foi estatisticamente significativa (p=0,019), também com o gênero em feminino (63,1%). Houve uma associação entre cárie e cristas alveolares normais (p<0,001) com idade, ambos em indivíduos mais jovens. Conclusões: O perfil epidemiológico da população foi composto por mulheres adultas de meia idade, a cárie foi a mais prevalente entre as lesões e as cristas alveolares entre os achados radiográficos
