Methods: Minimal inhibitory concentration assays were performed with Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Actinomyces odontolyticus, Streptococcus oralis, Streptococcus mitis, Streptococcus salivarius, Streptococcus sanguinis, and Streptococcus gordonii; checkerboard microdilution assays between simvastatin and standard antimicrobials; monospecies and multispecies biofilms. Results: simvastatin showed the best antimicrobial activity against most species (MIC range from 3.12 to 25 µg/mL), highlighting the sensitivity of P. gingivalis. In the checkerboard assay, synergistic interaction was found between simvastatin and amoxicillin against S. oralis and S. sanguinis. P. gingivalis biofilm was inhibited by simvastatin at 10 and 50x Minimal inhibitory concentration, with similar effects to metronidazole. For multispecies biofilm, SMV reduced the biofilm metabolic activity (79%) and total counts (87%), comparable to amoxicillin. simvastatin also reduced bacterial counts of Veilonnella parvula, P. gingivalis, Streptococcus mutans, Actinomyces naeslundii, P. intermedia, and Capnocytophaga ochracea in the multispecies biofilm. Conclusions: Simvastatin showed antimicrobial and antibiofilm activity against oral bacteria and may contribute to the control of dysbiosis, and may be considered in clinical studies as an adjuvant in the treatment of periodontitis. https://repositorioslatinoamericanos.uchile.cl/handle/2250/5363175 https://repositorioslatinoamericanos.uchile.cl/handle/2250/5363174 O saber de enfermagem sobre a relação enfermeiro-paciente em serviços de saúde mental Repositório de dados referente ao artigo "O saber de enfermagem sobre a relação enfermeiro-paciente em serviços de saúde mental", submetido à REBEN em julho de 2022. https://repositorioslatinoamericanos.uchile.cl/handle/2250/5363174 https://repositorioslatinoamericanos.uchile.cl/handle/2250/5363172 The impact of the Covid-19 pandemic on the training of brazilian paralympic powerlifting athletes Data resulting from the master's research carried out by student Erick Guilherme Peixoto de Lucena in order to describe the changes in training behaviors of Brazilian Para Powerlifters before and during the COVID-19 pandemic.
