Consumo de substâncias psicoativas entre estudantes de medicina antes e depois do ingresso no curso / Use of psychoactive substances among medicine students before and after admission to course

Introdução: Substâncias psicoativas são capazes de alterar a consciência, o humor ou o pensamento de um indivíduo, resultando em mudanças fisiológicas ou de comportamento. Objetivo: Este estudo avaliou se houve diferença no consumo de 13 substâncias psicoativas por estudantes de medicina, de uma faculdade privada do interior paulista, antes e depois do ingresso no curso. Método: Um questionário estruturado e impresso foi apresentado a ingressantes no curso de medicina, em abril de 2019, e, novamente, em dezembro, ao final do primeiro ano da graduação. Resultados: Na análise dos dados, foi realizado o Teste de Wilcoxon, com o emprego do programa estatístico JASP. No total, 90 estudantes participaram do estudo. Dentre as 13 substâncias consideradas, apenas para o álcool foram encontradas evidências estatísticas que indicaram ter ocorrido um aumento significativo no consumo após o ingresso no curso (W = 1308,00, p < 0,001). Conclusão: A continuidade dos estudos sobre o uso de substâncias lícitas e ilícitas entre os estudantes da instituição de ensino considerada será fundamental para garantir um monitoramento contínuo. Desse modo, a instituição poderá identificar usos abusivos e implementar políticas de prevenção, garantindo o bem-estar de seus alunos

Introduction: Psychoactive substances are capable of altering an individual's consciousness, mood or thinking, resulting in physiological or behavioral changes. Objective: This study assessed whether there was a difference in the consumption of 13 psychoactive substances by medical students at a private college in the interior of São Paulo, before and after enrolling in the course. Method: A structured, printed questionnaire was presented to new medicine students in April 2019, and again in December, at the end of the first year of graduation. Results: In data analysis, the Wilcoxon Test was performed, using the JASP statistical program. In total, 90 students participated in the study. Among the 13 substances considered, only for alcohol was statistical evidence found that indicated that there had been a significant increase in consumption after enrolling in the course (W = 1308.00, p < 0.001). Conclusion: Continuing studies on the use of legal and illicit substances among students at the educational institution considered will be essential to ensure continuous monitoring. In this way, the institution will be able to identify abusive uses and implement prevention policies, ensuring the well-being of its students

Evaluation of the healing properties of Garcinia brasiliensis extracts in a cutaneous wound model.

ETHNOPHARMACOLOGICAL RELEVANCE: Wound healing is a complex process that can leave pathological scars, especially in case of infections from opportunistic microorganisms. In this context, herbal medicines open up great possibilities for investigation. One of the species of interest native to Brazil is Garcinia brasiliensis ("bacupari"). Traditionally known for treating wounds and ulcers, G. brasiliensis presents anti-inflammatory, antioxidant and antimicrobials properties. But, its wound healing profile in experimental models, in order to validate its efficacy, is still litle studied. AIM OF THE STUDY: Thus, the objective of this work was to evaluate, in an infected cutanous wound model, the potential of formulations incorporated with G. brasiliensis leaves extracts. MATERIALS AND METHODS: Crude extract (CE), Ethyl Acetate Fraction (EAF) and Hexanic Fraction (HF) were submitted to phytochemical assays, high performance thin layer chromatography (HTPLC) and cytotoxicity studies. CE and EAF were also tested for microbicidal properties and incorporated in cream and gel formulations at 10% concentration. After stability testing, the gel formulations with CE or EAF at 10% were selected and applied to skin wounds infected or not with Staphylococcus aureus in Wistar rats. The healing potenttial of the extracts was verified by the expression of the protein Annexin A1 (AnxA1), related to the processes of inflammation and antifibrotic function, the cells immunostaining for Gasdermin-D (GSDM-D), a marker of pyroptotic cell death, and the dosage of interleukin-10 (IL-10) and monocyte chemotactic protein (MCP)-1 inflammatory mediators. RESULTS: Phytochemical studies indicated the presence of compounds of pharmacological interest, including Catechin, Quercetin and Berberine in addition to low cytotoxicity of CE and EAF at 10%. After the 6-day topical treatments, CE and EAF gel formulations demonstrated to control the pruritus formation process. The treatments decreased AnxA1 expression and the amount of cells immunostained for GSDM-D, and increased the expression of MCP-1 in infected wounds. CONCLUSIONS: Together, the results show important anti-inflammatory profile and skin healing potential of CE and EAF from G. brasiliensis leaves, even in infected lesions, with therapeutic perspectives.
