We concluded that patients from North (Amazon) region present higher plasma Se levels when compared to the patients from Southeast of Brazil. However, independently of the region, HD patients presented Se deficiency.

Bacteria that are resistant to several antibiotics are a serious One Health problem, as new alternatives for treatment do not appear at the same speed.  Thus, the aim of this work was to carry out a survey of studies involving the activity of the essential oil of O. vulgare and its isolated compound carvacrol on antibiotic-resistant bacteria.  To this end, a qualitative review of the literature was carried out in the PubMed database from 2015 to 2020. Both for the essential oil and for the isolated compound, the inhibitory action extends to strains often associated with difficult-to-treat infections such as oxacillin and vancomycin-resistant Staphylococcus aureus, β-lactamase-producing strains, carbapenemases, among others. The point that distinguishes the studies is the type of methodology used in the tests, with studies with carvacrol more directed towards mechanisms of molecular action and application in cells and animals, while those with oils are more preliminary. Although these substances have potential to control resistant bacteria, more research is needed to enable their use.

The genus Bauhinia popularly known as “pata-de-vaca”, “unha de vaca”, “unha de boi”, “unha de anta” e “casco de vaca” is widely used in the form of teas and other herbal preparations. The aim of this literature review was to show the diversity and biological potential of Bauhinia species for health promotion. A search was carried out for articles listing some species of medical interest. The pharmacological activities of B. forficata were also highlighted in articles published in the last twenty years using the PubMed database. Research has shown that Bauhinia is used as a hypoglycemic and antidiabetic agent, diuretic, cholesterol reducer, in the treatment of cystitis, intestinal parasites, elephantiasis, tumors and other ailments, including infections and painful processes. In the last eleven years, 86% of the works carried out with B. forficata used the plant collected or acquired in Brazil, predominantly publications from the southern region of the country where almost 60% reported activity on diabetes and its complications and/or antioxidant effect. Despite the literature pointing out the great medicinal potential of Bauhinia in chronic diseases and their complications, there is still a need for more translational research.

Para que haja um sistema de saúde eficiente, a participação da comunidade se faz essencial nesse processo, pois é direito da mesma expor suas necessidades para que novas ações relativas à saúde sejam tomadas. Nesse sentido, o Sistema Único de Saúde (SUS) tem em sua construção espaços que são destinados a esta prática, como os Conselhos e Conferências de Saúde. Todavia ainda é notório que os cidadãos brasileiros não ocupam estes espaços de maneira efetiva. Desta forma, o objetivo deste trabalho foi realizar uma revisão bibliográfica com o intuito de compreender os motivos que corroboram com a falta de participação da comunidade. As principais problemáticas levantadas após a pesquisa nas bases de dados foram a escassa compreensão da legislação vigente, sensação de obrigatoriedade (trabalho) e certa pressão do próprio sistema contra o cidadão. Todavia, nota-se que apesar das dificuldades, há formas de contornar essas barreiras, através da implementação de tecnologias de comunicação que facilitem o diálogo da população para com o Estado. Portanto, ainda que haja muitas dificuldades impostas no cotidiano dos cidadãos, existem formas do exercício da cidadania - participando da construção do SUS - que podem ser implementadas com o auxílio da tecnologia.
