Desafios da Psicologia Indígena no atendimento a estudantes universitários / Challenges of Indigenous Psychology in providing assistance to university students

Objetivo Este artigo tem como objetivo discutir a abordagem da psicologia indígena no cuidado de estudantes indígenas em contexto universitário. Método Utilizando o método qualitativo, este artigo apresenta um estudo de caso detalhando a trajetória de formação da Rede de Escuta e Desaprendizagens Étnico-Subjetivas, para analisar a aplicação dos pressupostos da psicologia indígena no suporte a estudantes indígenas e seus familiares na Universidade Estadual de Campinas. Resultados Evidenciou-se a necessidade de reconhecer diferentes epistemologias para uma conexão terapêutica respeitosa. Foram observados desafios na aplicação de práticas alinhadas com a psicologia indígena, destacando a coautoria nas sessões, a valorização das perspectivas dos pacientes e as desaprendizagens contínuas. O estudo dos elementos culturais das etnias envolvidas mostrou-se crucial para evitar a patologização das cosmovisões e subjetividades indígenas. Conclusão A psicologia indígena apresenta-se como um vetor de mudança nas disputas de narrativas culturais, destacando a lacuna na abordagem clínica e a necessidade urgente de estudos para desenvolver intervenções personalizadas para o atendimento das diferentes etnias indígenas.

Objective This article aims to discuss the approach of indigenous psychology in the care of indigenous students in a university framework. Method Using a qualitative method, this article presents a case study detailing the formation trajectory of the Rede de Escuta e Desaprendizagens Étnico-Subjetivas (Network of Ethno-Subjective Listen-ing and Unlearning) to review the application of the principles of indigenous psychology in sup-porting indigenous students and their families at Universidade Estadual de Campinas (Unicamp, State University of Campinas), Brazil. Results The study highlighted the need to recognize different epistemologies for respectful therapeutic connections. Challenges were faced in the application of practices aligned with indigenous psychology, emphasizing co-authorship in sessions, valuing patients' perspectives, and continuous unlearning. The study of the cultural elements of the ethnicities involved proved crucial to avoid the pathologization of indigenous worldviews and subjectivities. Conclusion Indigenous psychology presents itself as a tool for the changes in the cultural struggles, highlighting the gap in clinical approaches and the urgent need for further studies to develop personalized interven-tions for the care of the diverse indigenous ethnicities.

Rhynchophorus palmarum (Linnaeus, 1758) (Coleoptera: Curculionidae): Guarani-Kaiowá indigenous knowledge and pharmacological activities.

Zootherapy is a traditional secular practice among the Guarani-Kaiowá indigenous ethnic group living in Mato Grosso do Sul, Brazil. My people use the oil extracted from larvae of the snout beetle Rhynchophorus palmarum (Linnaeus, 1758) to treat and heal skin wounds and respiratory diseases. Based on this ethnopharmacological knowledge, the chemical composition and antioxidant, antimicrobial, and healing properties of R. palmarum larvae oil (RPLO) were investigated, as well as possible toxic effects, through in vitro and in vivo assays. The chemical composition of the RPLO was determined using gas chromatography coupled with mass spectrometry. The antioxidant activity of RPLO was investigated through the direct 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay, and the antimicrobial activity was evaluated against Gram-positive and Gram-negative bacteria that are pathogenic to humans. The healing properties of RPLO were investigated by performing a cell migration assay using human lung fibroblasts (MRC-5), and the toxicity was analyzed, in vivo, using a Caenorhabditis elegans model and MRC-5 cells, in vitro. RPLO contains 52.2% saturated fatty acids and 47.4% unsaturated fatty acids, with palmitic acid (42.7%) and oleic acid (40%) representing its major components, respectively. RPLO possesses direct antioxidant activity, with a half-maximal inhibitory concentration (IC50) of 46.15 mg.ml-1. The antimicrobial activity of RPLO was not observed at a concentration of 1% (v/v). RPLO did not alter the viability of MRC-5 cells and did not exert toxic effects on C. elegans. Furthermore, MRC-5 cells incubated with 0.5% RPLO showed a higher rate of cell migration than that of the control group, supporting its healing properties. Taken together, RPLO possesses direct antioxidant activity and the potential to aid in the healing process and is not toxic toward in vitro and in vivo models, corroborating the safe use of the oil in traditional Guarani-Kaiowá medicine.

The immunoregulatory function of polyphenols: implications in cancer immunity.

Polyphenols have demonstrated several potential biological activities, notably antitumoral activity dependent on immune function. In the present review, we describe studies that investigated antitumor immune responses influenced by polyphenols and the mechanisms by which polyphenols improve the immune response. We also discuss the limitations in related areas, especially unexplored areas of research, and next steps required to develop a therapeutic approach utilizing polyphenols in oncology.
