This study presents updated information on six exotic aquatic species (five crustaceans and one fish): Macrobrachium rosenbergii, Penaeus monodon, Charybdis hellerii, Balanus trigonus, Amphibalanus improvisus, and Pterois volitans. The research is based on bibliographic information available in scientific articles published by the Research Group Fishing and Evaluation of Tropical Fishery Resources and Biological and Photographic Records obtained from research projects conducted by CEPNOR/ICMBio. Currently, M. rosenbergii shrimp is classified as an invasive species, P. monodon is classified as a detected species, and C. hellerii is currently classified as an established species, but there are strong indications that it should be reclassified as invasive. The barnacles A. improvisus and B. trigonus have been classified as invasive, and lionfish P. volitans strongly exhibits advanced invasion process owing to its high frequency of capture in commercial fisheries.

The lionfish Pterois volitans (Linnaeus, 1758) is considered the most well-established fish species in non-native regions around the world, causing severe environmental damage and risks for the food chain. In Brazil, the lionfish was reported for the first time in 2014 in the State of Rio de Janeiro, and currently, the P. volitans was observed in more eight States, being its high level of occurrence in the Northern region, which contains an immense biodiversity that has not been totally cataloged yet. Based on that, this study aims to ratify the occupation and permanent residence of the lionfish in the Great Amazon Reef System (GARS), which is an alert for the urgent need for developing control strategies for this invasive species in Brazil. The new specimens were collected in the State of Amapá, between 2021 and 2022, during commercial lobster fishing, using the method of “Caçoeira”, covering between 70 and 100 meters of depth, while for the snapper was collected with the manzuá, between 78 and 102 meters of depth. In the laboratory, the individuals were measured in total length (TL) and total weight (TW). 21 specimens of P. volitans from the GARS, the TL ranged from 21,5 to 35,6 cm with an average of 29,43 cm, while the TW ranged from 150,0 to 733,0 g, with an average of 413,8 g. These adult specimens reinforce the stabilization of the lionfish, which have probably completed reproductive cycles in the region, requiring an urgent action by environmental agencies to control the invasion of the lionfish in Brazil, becoming a future environmental impact on native biodiversity.

RESUMO Objetivo: Mapear a produção científica nacional e internacional sobre os estudos de soroepidemiologia da sífilis nas doações de sangue em bancos reguladores. Método: Estudo bibliométrico, realizado entre abril e junho de 2024, junto às bases de dados Web of Science, Scopus, Lilacs, Medline e PubMed, fundamentado na aplicação das leis de Bradford, Lotka e Zipf. Resultado: Publicação majoritária em artigos de periódicos com 2.010 produções (87,54%), em idioma inglês 1.815 (88,97%), ano de maior produção foi 2020, com 95 (4,64%) publicações; termos com maior peso de citação e correlação dentro do tema foram: “Blood donor”, “Humans”, “male”, “Female”, “Prevalence”, “Blood banck”. Conclusão: A análise bibliométrica demonstrou a evolução das publicações, bem como a necessidade das pesquisas para o conhecimento do perfil epidemiológico da sífilis na população de doadores de sangue, de forma global e em territórios específicos. Estes indicadores podem nortear a triagem de doadores e ações de combate à sífilis.

O presente estudo tem como o objetivo avaliar o perfil epidemiológico da saúde nutricional dos pescadores artesanais da cidade paraense de São Caetano de Odivelas. A coleta de dados ocorreu, entre Agosto e Novembro de 2022, com pescadores artesanais cadastrados e efetivos junto a Colônia de Pescadores Z-4. Participaram do estudo 78 pescadores profissionais membros da colônia com idade entre 20 e 65 anos de ambos os gêneros. O instrumento de coleta foi via questionário socioeconômico e demográfico por meio de ficha de cadastro e acompanhamento nutricional do Sistema de Vigilância Alimentar e Nutricional modificada e adequada aos parâmetros de indicadores antropométricos. A maioria dos pescadores apresentam sobrepeso ou obesidade, o que pode ser um fator de risco para o desenvolvimento de várias doenças crônicas não transmissíveis, como diabetes tipo 2, doenças cardiovasculares e algumas formas de câncer. Medidas de vigilância nutricional e de saúde devem ser integradas às atividades de pesca para identificar e tratar precocemente doenças crônicas não transmissíveis na população.

Internationalization has become both an organizing ideal and an evaluative metric in graduate education, yet its dominant forms remain shaped by competition, rankings, and asymmetries between academic centers and peripheries. This essay offers a conceptual and reflective contribution to that debate from an underrepresented standpoint: a graduate nursing program located in the Brazilian Amazon. Drawing on critical reflection and a purposive reading of the higher education and nursing literature, it examines how internationalization is conceptualized, how it has unfolded in Brazil, and what structural barriers and pathways shape its trajectory in regions distant from the country’s academic core. We argue that prevailing models, organized around mobility and productivity, tend to reproduce center–periphery hierarchies and to frame internationalization as an external imperative rather than a situated, relational, and ethical process. The Brazilian case shows uneven advancement, with opportunities concentrated in consolidated institutions of the South and Southeast and persistent barriers of funding instability, linguistic inequity, bureaucracy, and fragile institutional policies. Read from the Amazon, these dynamics point toward a situated internationalization grounded in equity, reciprocity, South–South cooperation, internationalization at home, and the social mission of public universities. The contribution lies in showing how a peripheral, discipline-specific standpoint can sharpen critical internationalization debates and widen the range of voices that shape the field of higher education.

(1) Background: Reactive syphilis screening makes a donor ineligible and sends the associated components to discard. This study estimated the donation-level prevalence of VDRL seroreactivity and its sociodemographic, temporal and geographic distribution in the catchment area of a regional blood service in Pará, Brazil, 2017–2023. (2) Methods: Census-based retrospective analysis of 362,705 donations recorded in the SBS.Web system of the Pará State Hemotherapy and Hematology Foundation, covering the six municipalities served by its central unit. The donation was the unit of analysis; records could not be deduplicated by donor. Confirmatory treponemal results were unavailable, so active, treated and false-positive reactions could not be distinguished. (3) Results: 3730 donations were reactive (1.03%; 95% CI 0.99–1.06). Annual prevalence rose from 0.69% (0.62–0.76) in 2017 to 1.29% (1.19–1.39) in 2021, then fell to 1.04% (0.95–1.13). Mean donor age fell from 40.1 to 33.8 years. Reactive records were 51.0% male, 71.5% single, 61.7% secondary education, 63.4% spontaneous donations. Belém held 67.9% of them (prevalence 1.01%; 0.97–1.05) and was the only municipality with a rising trend (p = 0.02). (4) Conclusions: Roughly one donation in a hundred was withdrawn from the transfusion chain, with the counseling and re-entry work each case entails. These are screening results, not confirmed infections, and measure an operational burden rather than syphilis prevalence.
