    A Giárdia é o mais comum e o primeiro protozoário a ser encontrado em seres humanos, ele é comumente encontrado em países emergentes onde sua população tem uma economia desestruturada com saneamento e hábitos de higiene precária. Devido sua transmissão ser por ingestão de alimentos contaminados, água tratada de maneira incorreta, os manipuladores de alimentos acaba sendo os facilitadores dessa contaminação. Essas pessoas devem passar por uma capacitação de modo que entendam a problemática em questão

    Análise dos casos de COVID-19 em uma cidade no sertão da Paraíba: Analysis of COVID-19 cases in a city in the sertão of Paraíba

    Trata-se de uma análise epidemiológica sobre as notificações de síndrome gripal (SG) com o SARS-CoV-2 como agente etiológico em uma cidade do sertão da Paraíba, tomando base o início das notificações no e-SUS Notifica, em março de 2020, até a última semana epidemiológica de 2021. Tem por objetivo analisar o perfil dos casos de COVID-19, registrados, o que ajuda a entender o comportamento da pandemia ao longo do tempo, bem como observar a efetividade da vacinação. A partir desta pesquisa, constatou-se que a cidade de Pombal-PB teve 5.023 notificações de casos de SG, mas apenas 2.201 se enquadraram nos critérios para análise. Destes, 46,5% eram do sexo masculino e 53,5% do sexo feminino.  As informações coletadas também demostraram uma discrepância entre esses dados e os disponíveis pelo governo do Estado da Paraíba, tanto pelo fato do Estado ter acesso a outros sistemas de coleta de informações, como por faltas durante os registros no sistema. Além disso, observou-se que as manifestações clínicas mais descritas foram dor de garganta (35,8%, N=853), tosse (34,9%, N= 768) e febre (34,3%, N= 754), o que divergiu da literatura encontrada. Entretanto, este estudo ainda é falho devido à subnotificação dos casos, de forma que não se tem como afirmar a confiabilidade da informação. Dessa forma, sugerimos que estratégias amplas sejam implementadas para fechamento dos casos em aberto no sistema, além de capacitação dos profissionais responsáveis pela digitalização de tais registros, para que, no futuro, tenhamos dados públicos mais fidedignos com a realidade

    Introduction: Tetralogy of Fallot involves four specific heart problems. Firstly, there is pulmonary stenosis, characterized by the narrowing of the pathway that carries blood from the heart to the lungs, hindering blood flow. Right ventricular hypertrophy is another characteristic, where the muscle of the right ventricle of the heart becomes thicker due to increased workload caused by pulmonary stenosis. Methodology: The present study adopted a descriptive epidemiological approach with the aim of analyzing cases of Tetralogy of Fallot among live births in Brazil from 2012 to 2021. Data collection utilized the Live Birth Information System (SINASC), made available by DATASUS. Results: In the group of individuals born with Tetralogy of Fallot, the analysis of variables reveals valuable information about demographic characteristics and perinatal conditions. Regarding the "Race/Ethnicity" variable, out of the 943 cases registered, 588 (62.35%) were classified as white, 51 (5.41%) as black, 10 (1.06%) as yellow, 267 (28.31%) as brown, and 27 (2.86%) had race/ethnicity recorded as unknown. Conclusion: A profound understanding of congenital heart diseases not only saves lives but also significantly improves the quality of life for affected individuals.Introdução: A Tetralogia de Fallot envolve quatro problemas cardíacos específicos. Em primeiro lugar, há a estenose pulmonar, caracterizada pelo estreitamento da via que conduz o sangue do coração para os pulmões, dificultando o fluxo sanguíneo. A hipertrofia ventricular direita é outra característica, onde o músculo do ventrículo direito do coração torna-se mais espesso devido ao aumento da carga de trabalho provocado pela estenose pulmonar. Metodologia: O presente estudo adotou uma abordagem epidemiológica descritiva com o objetivo de analisar os casos de Tetralogia de Fallot entre os nascidos vivos no Brasil no período de 2012 a 2021. Para a coleta de dados, utilizou-se o Sistema de Informações sobre Nascidos Vivos (SINASC), disponibilizado pelo DATASUS Resultado: No grupo de nascidos com Tetralogia de Fallot, a análise das variáveis revela informações valiosas sobre características demográficas e condições perinatais. Em relação à variável "Cor/Raça", dos 943 casos registrados, 588 (62,35%) eram classificados como brancos, 51 (5,41%) como pretos, 10 (1,06%) como amarelos, 267 (28,31%) como pardos, e 27 (2,86%) tiveram a cor/raça registrada como ignorada Conclusão: A compreensão profunda das cardiopatias congênitas não apenas salva vidas, mas também melhora significativamente a qualidade de vida dos indivíduos afetados

     A qualidade de  vida de pacientes vivendo com HIV/AIDS é essencial, tendo em vista o caso específico dos adolescentes é ainda mais importante porque o jovem além de lidar com a resistência e a aceitação da doença, deve também enfrentar os conflitos da puberdade.O presente trabalho tem como objetivo realizar uma revisão integrativa em relação a qualidade de vida dos pacientes com HIV. Trata-se de um estudo de revisão integrativa realizado no período de 2016 a 2017, utilizando-se o banco de dados Medline e Lilacs. Apesar do impacto da infecção pelo HIV/AIDS na saúde psicológica e nas relações sociais dos indivíduos infectados, assim como no domínio físico, o uso da TARV provocou consequências positivas na saúde psicológica, proporcionando a desconstrução da ideia de morte advinda ao diagnóstico de portador do HIV/AIDS e a construção de melhores perspectivas de vida. A adesão ao tratamento em HIV/AIDS está relacionada a um aumento da sobrevida e de sua qualidade. Porém deve-se respeitar a posição pessoal do portador para fazer ou não o tratamento

    Aim: Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location: Amazonia. Taxon: Angiosperms (Magnoliids; Monocots; Eudicots). Methods: Data for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran\u27s eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny. Results: In the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2^{2} = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2^{2} = 28%). A greater number of lineages were significant indicators of geographic regions than forest types. Main Conclusion: Numerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

    Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types
