BackgroundThe present study aimed to evaluate the possible acute oral toxicity of Baccharistrimera leaf dye as well as its antimicrobial activity.MethodOrganization for Economic co-operation and development (OECD) 423 was used to assess acute oral toxicity and as per protocol a dose of 2000 mg/kg of tincture was administered to Wistar rats, male and female, and observed for 14 days. Biochemical and hematological analyzes were performed with sample collected of rat. The dye was evaluated for antimicrobial activity by agar diffusion and microdilution methods, which allow to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) and antibiofilm potential.ResultsThe results showed that there was no loss of animals and no significant changes in hematological and biochemical parameters after oral administration of 2000 mg/kg of tincture and was considered safe by the OECD, classified as category 5. The dyeing also showed an important antimicrobial activity against gram positive and gram negative bacteria also significantly decreased the microbial biofilm.ConclusionThe tincture of B.trimera leaf when given orally once can be considered safe and has a relevant antimicrobial potential that should be elucidated in subsequent research.
Estudo metodológico de construção de material educativo impresso (MEI) sobre armazenamento correto de medicamentos nos domicílios e validação por 50 usuários dos serviços de saúde e 52 juízes – profissionais da área de saúde. O MEI aborda a maneira correta de armazenar medicamentos, riscos de degradação, ineficiência e intoxicação acidental. A validação de conteúdo foi estabelecida a partir do Level Content Validity Index(CVI) maior que 0,8 para juízes, os quais avaliaram a relevância de informações, clareza, compreensão de texto e ilustrações e aplicabilidade do material. Os usuários analisaram o MEI quanto aos parâmetros de aparência, motivação, conteúdo e organização escrita. Todos os itens foram considerados relevantes pelos avaliadores e o CVI-médio entre juízes foi de 0,96, e entre os usuários, de 0,94. O MEI validado foi utilizado em ações de promoção da saúde apresentando-se como uma ferramenta altamente relevante, técnica e acessível para conscientização sobre o armazenamento correto de medicamentos.
Objective The aim of this study was to systematically review literature on the use of iron supplements (not including iron derived from diet), increased levels of hemoglobin and/or ferritin, and the risk of developing gestational diabetes mellitus (GDM).
Data source The following databases were searched, from the study's inception to April 2021: PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl and Lilacs.
Selection of studies A total of 6,956 titles and abstracts were reviewed, 9 of which met the final inclusion criteria, with 7,560 women in total.
Data collection Data extraction was performed by two independent reviewers and disagreements were resolved by a third researcher.
Data synthesis Methodological quality in controlled trials were assessed according to the Cochrane Collaboration tools (ROB-2 and ROBINS-1) and for the observational studies, the National Institutes of Health's (NIH) quality assessment tool was used. Among the 5 observational studies, women with a higher hemoglobin or ferritin level were more likely to develop GDM when compared with those with lower levels of these parameters. Among the 3 randomized clinical trials, none found a significant difference in the incidence of GDM among women in the intervention and control groups. However, we identified many risks of bias and great methodological differences among them.
Conclusion Based on the studies included in this review, and due to the important methodological problems pointed out, more studies of good methodological quality are needed to better establish the association between iron supplementation and GDM.
Objetivo: Avaliar a forma de armazenamento e descarte de medicamentos pela comunidade acadêmica de universidade federal do Rio Grande do Sul. Métodos: Estudo transversal, realizado entre junho e agosto de 2017 abrangendo a comunidade acadêmica (alunos e servidores). Resultados: Dos 170 entrevistados, 85,3% armazenam medicamentos em domicílio, destacando-se o quarto como principal local de armazenamento (48,6%). O hábito de armazenar medicamentos por alunos não esteve associado ao sexo, idade, escolaridade de pais, nível e período do curso ou área acadêmica ou ainda situação de residência (p>0,05). A situação de residência esteve associada significativamente (p=0,022) com a prática de monitoramento de validade. Considerando as práticas de descarte, 70,9% da comunidade acadêmica descarta em lixo comum. O descarte incorreto de medicamentos realizados por servidores esteve associado à escolaridade das mães (p=0,018) e ao sexo (p=0,031). Conclusão: Independente das características sócio demográficas, a maioria da população pratica o armazenamento e relatou descarte incorreto de medicamentos. Este diagnóstico subsidiou ações institucionais de conscientização e auxilia potencialmente outras instituições de ensino superior na adoção de medidas coletivas de educação em saúde.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
