    Introdução: O condiloma acuminado, causado pelos HPV’s, vírus do papiloma humano, é uma das infecções sexualmente transmissíveis mais recorrentes no mundo e que se manifesta através de lesões papilomatosas. Esses vírus, pertencentes à família Papoviridae, possuem tropismo pelas células epitelias, o que ocasiona infecções na pele e nas mucosas genital, oral, da laringe e do esôfago. HPV’s de alto risco, por sua vez, se relacionam intimamente ao câncer cervical. A transmissão se dá através de relações sexuais, tanto vaginais como anais, através do contato direto com a pele infectada e o diagnóstico é preferencialmente clínico/histocitopatológico. Portanto, se tratando de uma enfermidade prevalente, é notório que acadêmicos de medicina tenham maior acesso à informação e, consequentemente, níveis de conhecimento além da literatura devido aos cursos de IST´s em seu currículo. Métodos: A coleta de dados se deu por questionário de conhecimento acerca do vírus do papiloma humano (HPV), autoaplicado, desenvolvido e validado para o idioma inglês em 2012, e adaptado para o português pelos autores.Resultados: observou-se que, no 3° período: 14,28% dos estudantes obtiveram 27 acertos; 14,28% obtiveram 26 acertos; 14,28% obtiveram 25 acertos; 14,28% obtiveram 24 acertos; 21,43% obtiveram 21 acertos e 21,43% obtiveram 18 acertos. No 4° período, observou-se: 14,28% dos estudantes obtiveram 27 acertos; 7,14% obtiveram 26 acertos; 14,28% obtiveram 24 acertos; 28,57% obtiveram 23 acertos; 21,43% obtiveram 22 acertos e 14,28% obtiveram 21 acertos. No 5° período, os resultados foram: 14,28% dos estudantes obtiveram 27 acertos; 21,43% obtiveram 26 acertos; 7,14% obtiveram 25 acertos; 28,57% obtiveram 24 acertos; 21,43% obtiveram 23 acertos e 7,14% obtiveram 21 acertos.

    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

    Potenciais interações de drogas em pacientes de terapia antirretroviral: uma revisão integrativa: Potential drug interactions in antiretroviral therapy patients: an integrative review

    Get PDF
    Possíveis interações medicamentosas devem ser levadas em consideração ao selecionar um regime antirretroviral. Uma revisão detalhada dos medicamentos concomitantes pode ajudar na criação de um regime que minimize as interações indesejáveis. O potencial para interações medicamentosas deve ser avaliado quando qualquer novo medicamento (incluindo agentes de venda livre) é adicionado a um regime antirretroviral existente. A maioria das interações medicamentosas com medicamentos antirretroviral é mediada por inibição ou indução do metabolismo hepático de medicamentos. Este estudo trata-se de uma revisão integrativa, cujo objetivo foi compreender as possíveis interações de drogas em pacientes com infecção pelo HIV em processo de terapia antirretroviral. Após análise dos dados, concluiu-se que há riscos reais de interações medicamentosas a partir do uso de 5 ou mais medicamentos, por um tempo superior a seis anos. Os principais riscos apontados nesse sentido foram interferência na resposta terapêutica, aumento de reações adversas toxidade nos sistemas cardiovascular e nervoso central e dificuldades para detecção de resistência do HIV aos medicamentos antirretrovirais

    Estimating the global conservation status of more than 15,000 Amazonian tree species

    Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict thatmost of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century

    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

    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
