Infecção por enteroprotozoários zoonóticos em população de comunidades, Pernambuco-Brasil / Zoonotic enteroprotozoan infection in communitypopulation, Pernambuco-Brazil

Infecções causadas por enteroprotozoários representam um importante problema em saúde pública. Enteroprotozoários são responsáveis por infecções que acometem o intestino de seu hospedeiro com possível transmissão por animais ao homem. A transmissão ocorre, principalmente, por meio da via fecal-oral com a ingestão de água e alimentos contaminados. As condições socioeconômicas desfavoráveis são fatores que favorecem a presença de protozoários entéricos no Nordeste brasileiro. O presente trabalho objetivou estimar a frequência dos enteroprotozoários e analisar a associação entre a infecção por enteroprotozoários e as condições higiênico-sanitárias e sociodemográficas de comunidades do Recife, Goiana, Igarassu e Camaragibe - estado de Pernambuco, Brasil. Os indivíduos participantes foram convidados a assinar um termo de Consentimento e Livre Esclarecido. As amostras fecais foram submetidas a exames parasitológicos, utilizando as técnicas de Willis (flutuação simples), Hoffman (sedimentação espontânea), Faust (centrífugo-flutuação), kato-katz, sistema Coproplus e centrífugo-sedimentação em formol éter confeccionando-se três lâminas para cada amostra em cada tipo de exame realizado. No total de amostras fecais analisadas a positividade foi de 15,5%, com frequência de infectados significativamente maior para pessoas com renda até um salário mínimo, detectando-se predominantemente Isospora belli além de Entamoeba spp. e Giardia spp. Conclui-se que a infecção por enteroprotozoários está presente nas comunidades analisadas, associada à renda familiar dos indivíduos e favorecida por condições socioeconômicas desfavoráveis e condições higiênico-sanitárias inadequadas.

Inflammatory Response and Activation of Coagulation after COVID-19 Infection

SARS-CoV-2 (COVID-19) infection is responsible for causing a disease with a wide spectrum of clinical presentations. Predisposition to thromboembolic disease due to excessive inflammation is also attributed to the disease. The objective of this study was to characterize the clinical and laboratory aspects of hospitalized patients, in addition to studying the pattern of serum cytokines, and associate them with the occurrence of thromboembolic events. Methodology: A retrospective cohort study with 97 COVID-19 patients hospitalized from April to August 2020 in the Triângulo Mineiro macro-region was carried out. A review of medical records was conducted to evaluate the clinical and laboratory aspects and the frequency of thrombosis, as well as the measurement of cytokines, in the groups that presented or did not present a thrombotic event. Results: There were seven confirmed cases of thrombotic occurrence in the cohort. A reduction in the time of prothrombin activity was observed in the group with thrombosis. Further, 27.8% of all patients had thrombocytopenia. In the group that had thrombotic events, the levels of IL1b, IL-10, and IL2 were higher (p < 0.05). Conclusions: In the studied sample, there was an increase in the inflammatory response in patients with thrombotic events, confirmed by the increase in cytokines. Furthermore, in this cohort, a link was observed between the IL-10 percentage and an increased chance of a thrombotic event

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
