Abstract Objective To analyze the incidence and avoidability of adverse events in adult patients hospitalized in an emergency care unit in the countryside of Minas Gerais. Methods A cohort study, with a retrospective review of 296 medical records using screening (phase 1) and evaluation (phase 2) forms, completed by non-medical professionals and physicians, respectively. In the first phase, the demographic data, clinical condition of the patients, potential adverse events, and the verification of the quality of the information recorded in the medical records were evaluated. In the second phase, previously tracked adverse events were identified and characterized. Results There was a predominance of men, white, aged 60 or older. The cumulative incidence of adverse events was 4.4% (n=13), all of which were considered preventable, and mostly characterized as mild in severity. According to nature, 81.2% of adverse events were related to care in general. In relation to intrinsic and extrinsic factors, an average of 1.17 and 1.5 per patient, respectively, was found. It was found that a total of 17 patients were identified with potential adverse events, with 22 incidents in the analysis. Conclusion It was identified that 100% of adverse events were preventable and most related to general care. These findings reinforce the need to assess and understand the incidence and preventability of adverse events in emergency care units, which allows for the planning and implementation of strategies aimed at the development of control and response actions to these events, ensuring safe and quality care.

Prevalence of Trichomonas vaginalis and risk factors in women treated at public health units in Brazil: a transversal study.

BACKGROUND: Studies have revealed high prevalence rates of Trichomonas vaginalis in men and women worldwide. In Brazil, where reporting is not mandatory, the true prevalence rate is unknown. This study determined the prevalence of the parasite in women attending public health units in the city of Uberlândia, Minas Gerais, Brazil, identifying possible risk factors for infection, and also compared three diagnostic techniques for detecting the parasite. METHODS: Samples of vaginal secretions collected from 742 women attending public health units were analyzed by direct wet mount examination, culture and smear test. Epidemiological questionnaires were administered. RESULTS: Of the total of 742 samples analyzed, 19 (2.6%) tested positive for T. vaginalis. The variables significantly associated with infection were: being of black ethnicity, smoking, having knowledge about sexually transmitted diseases and presenting clinical signs. The culture method was considered the gold standard test. CONCLUSIONS: Although there are programs to control other sexually transmitted diseases, there are none for trichomoniasis. The results of this study indicate the presence of T. vaginalis in the female population, and points to the need for more research in Brazil to gain a better understanding of the profile and epidemiology of the parasite.

The inactive form of glycogen synthase kinase-3ß is associated with the development of carcinomas in galectin-3 wild-type mice, but not in galectin-3-deficient mice.

Galectin-3 has been implicated in the tumor development via its mediation of the Wnt signaling pathway. Likewise, glycogen synthase kinase-3beta (GSK3ß) also plays a role in the Wnt signaling pathway by controlling the levels of cytoplasmic beta-catenin. Altered GSK3ß expression has been described in various tumors, but to date, there are no studies evaluating its expression in models of oral carcinogenesis. Additionally, it is unknown whether the absence of galectin-3 regulates the expression of GSK3ß. To this end, Gal3-deficient (Gal3(-/-)) and wild-type (Gal3(+/+)) male mice were treated with 4NQO for 16 weeks and sacrificed at week 16 and 32. The tongues were removed, processed, and stained with H&E to detect dysplasias and carcinomas. An immunohistochemical assay was performed to determine the level of P-GSK3ß-Ser9 expression in both groups. Carcinomas were more prevalent in Gal3(+/+) than Gal3(-/-) mice (55.5% vs. 28.5%), but no statistical difference was reached. In the dysplasias, the proportion of cells positive for P-GSK3ß-Ser9 was slightly higher in Gal3(+/+) than Gal3(-/-) mice (63% vs. 61%). In the carcinomas, a significant difference between Gal3(+/+) and Gal3(-/-) mice was found (74% vs. 59%; p=0.02). P-GSK3ß-Ser9-positive cells slightly decreased from the progression of dysplasias to carcinomas in Gal3(-/-) mice (61% vs. 59%; p>0.05). However, a significant increase in P-GSK3ß-Ser9 expression was observed from dysplasias to carcinomas in Gal3(+/+) mice (63% vs. 74%; p=0.01). In conclusion, these findings suggest that fully malignant transformation of the tongue epithelium is associated with increased P-GSK3ß-Ser9 expression in Gal3(+/+) mice, but not in Gal3(-/-) mice.

Expressão de galectina-3 e beta-catenina em lesões pré-malignas e carcinomatosas de língua de camundongos / Galectin-3 and beta-catenin expression in premalignant and carcinomatous lesions in tongue of mice

INTRODUÇÃO: A galectina-3 (GAL3) apresenta importantes papéis na biologia tumoral e recentemente foi mostrada a sua participação na via de sinalização Wnt, translocando a beta-catenina para o núcleo. Expressão alterada de GAL3 e beta-catenina tem sido descrita em cânceres, mas não há estudos avaliando a expressão de ambas em displasias e carcinomas desenvolvidos em modelos de carcinogênese de língua. OBJETIVOS: Estudar a expressão de GAL3 e beta-catenina em lesões displásicas e carcinomas induzidos experimentalmente em língua de camundongos. MATERIAL E MÉTODOS: Vinte camundongos C57BL/6 machos foram desafiados com 4NQO na água de beber por 16 semanas e sacrificados na semana 16 e 32. Após o sacrifício, as línguas foram removidas, processadas, coradas por hematoxilina e eosina (HE) para detecção de displasias e carcinomas. Ensaio imuno-histoquímico foi realizado para determinar o índice de positividade para GAL3 e beta-catenina nessas lesões, bem como uma correlação entre elas em carcinomas. RESULTADOS: O número de camundongos afetados por carcinoma aumentou entre as semanas 16 e 32 (22,2 por cento vs. 88,9 por cento) e o de displasia diminuiu (66,7 por cento vs. 11,1 por cento). Um aumento de células positivas para beta-catenina não membranosa e GAL3 citoplasmática foi observado nas displasias e nos carcinomas, mas essa diferença não foi estatisticamente significativa. No entanto, um aumento estatisticamente significativo de GAL3 nuclear foi observado na evolução de displasia para carcinoma (p = 0,04). Nenhuma correlação foi encontrada entre beta-catenina e GAL3. CONCLUSÃO: Tanto nas displasias quanto nos carcinomas a via de sinalização Wnt está ativa, e o aumento de GAL3 nuclear nos carcinomas sugere um papel na transformação maligna do epitélio lingual.

INTRODUCTION: Galectin-3 plays pivotal role in tumor biology and its participation in Wnt signaling pathway translocating beta-catenin into the nucleus has been recently demonstrated. Altered galectin-3 and beta-catenin expressions have been described in different tumors, however, there are no studies evaluating their expression in dysplasias and carcinomas induced in carcinogenic tongue models. OBJECTIVES: To study galectin-3 and beta-catenin expressions in dysplasias and carcinomas experimentally induced in mouse tongue. METHODS: Twenty C57Bl/6 male mice were treated with 4NQO in their drinking water for 16 weeks and sacrificed at weeks 16 and 32. Tongues were removed, routinely processed, and stained with hematoxylin and eosin to detect dysplasias and carcinomas. An immunohistochemical assay was performed to determine the level of positivity for galectin-3 and beta-catenin in these lesions as well as their correlation in carcinomas. RESULTS: The number of mice affected by carcinomas increased from week 16 to week 32 (22.2 percent vs. 88.9 percent) and the number affected by dysplasias decreased (66.7 percent vs. 11.1 percent). There was an increase in non-membranous beta-catenin- and cytoplasmic galectin-3-positive cells in dysplasias and carcinomas, although this difference was not statiscally significant. Nonetheless, there was a significant increase of nuclear galectin-3-positive cells in the evolution from dysplasia to carcinoma (p = 0.04). There was no correlation between beta-catenin and galectin-3. CONCLUSION: Wnt signaling pathway is active in both dysplasias and carcinomas and the increase of nuclear galectin-3-positive cells in carcinomas suggests its influence on malignant transformation in the tongue epithelium.
