The use of reverse abdominoplasty for treatment of chemical burn in the thoracoabdominal region

Chemical burn is a challenge owing to its severity compared to thermal burns. The depth and extent of lesions in different areas of the body lead us to look for different possibilities for the best treatment of the patient. A reverse abdominoplasty surgical technique was proposed; this involves a skin flap that could reduce the exposed area of a chemical burn. The result was satisfactory, reducing the patient's treatment, surgical and hospitalization time, highlighting the proposed technique as an important tool for thoracoabdominal reconstruction

Índice de depressão em acadêmicos de medicina de uma instituição particular de Minas Gerais / Depression index in medical academics of private institution of Minas Gerais

Introdução: A depressão é um distúrbio psíquico que causa sintomas como: autocrítica, choro, irritabilidade, preocupação somática, perda de energia e fadiga. Pesquisas científicas relataram que a taxa de depressão em estudantes de medicina é maior em relação à média da população geral. A preocupação com a saúde mental dos estudantes surge diante da análise desses relatos. Objetivo: identificar a prevalência de depressão nos acadêmicos de medicina de uma instituição de ensino particular do município de Juiz de Fora – MG. Método: Estudo observacional do tipo transversal, de abordagem quantitativa com 235 alunos de uma faculdade privada de Juiz de Fora, a partir da entrevista com aplicação de dois questionários: Inventário de Depressão de Beck-I (BDI-I) e um sobre dados socioeconômicos. As respostas dos questionários foram transferidas para o programa Access, onde foi criado um banco de dados para ser feita a análise comparativa entre eles. Resultados: Dos participantes do presente estudo a idade média observada foi de 24,2 anos em ambos os sexos, 95,3% tinham estado civil solteiro, 66,8% relataram emigração do estado de origem para o início da graduação e 75,3% possuíam renda familiar superior a oito salários mínimos. O índice geral de depressão encontrado foi de 17%, sendo mais acentuado no sexo feminino (19,6%). Após análise, 8,5% foram classificados com depressão leve, 6,4% com moderada e 2,1% com grave, possuindo incidência mais elevada no ciclo básico (22,2%). Dos estudantes que moravam sozinhos há relatos de algum grau de depressão em 22,5%, já os que moravam com família 12,6%. Conclusão: A prevalência de sintomas depressivos em acadêmicos de medicina foi alta, apresentando principalmente sintomas como autocrítica, choro, irritabilidade, preocupação somática, perda de energia e fadiga. Com isto, levantou-se a importância do apoio psicológico, psiquiátrico e pedagógico para os alunos que precisam de adaptações, principalmente durante o ciclo básico no qual foram encontrados maiores índices de depressão. 

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
