Impacto da disseminação de informação sobre endometriose no autocuidado de adolescentes de escola pública / Impact of dissemination of information about endometriosis on self-care of public school adolescents

Objetivo: Averiguar o conhecimento das adolescentes sobre endometriose, que é uma doença estrogênio-dependente, podendo ser progressiva, e que se caracteriza pela presença do tecido endometrial fora do útero. Estima-se que a endometriose acometa cerca de 10% das mulheres em idade reprodutiva, sendo 4% a 17% das adolescentes. Métodos: A pesquisa foi desenvolvida com adolescentes estudantes do terceiro ano do ensino médio de escolas estaduais do município de Avaré (São Paulo) de forma descritiva, exploratória e quali-quantitativa, em três etapas: aplicação de questionário, realização de palestra e nova aplicação de questionário. Participaram quatro escolas, totalizando 80 adolescentes participantes na primeira fase e 48 adolescentes na terceira fase. Resultados: Houve aumento de 21,35 vezes no número de adolescentes que se beneficiaram dos conhecimentos gerados pelas palestras, além da replicação da informação para terceiros, possivelmente aumento no número de mulheres que tomaram conhecimento sobre o que é endometriose. Conclusão: Verificou-se que a aplicação de palestras informativas sobre sinais e sintomas de endometriose aumentou o grau de conhecimento de adolescentes entre 16 e 17 anos de escola pública.

Objective: To investigate the knowledge of adolescents about Endometriosis, which is a progressive, estrogen/dependent disease, which can be progressive and which is characterized by the presence of endometrial tissue outside the uterus. It is estimated that it affects about 10% of women of reproductive age, of which 2%-4% are postmenopausal, with or without hormonal treatment, and 4% to 17% of adolescents. Methods: The research was carried out with adolescent students in the 3rd year of high school from state schools in the city of Avaré (São Paulo) in a descriptive, exploratory and qualitative-quantitative manner in three stages: application of a questionnaire, holding a lecture and a new application of quiz. Four schools participated, totaling 80 adolescents participating in the first phase and 48 adolescents in the third phase. Results: There was a 21.35-fold increase in the number of adolescents who benefited from the knowledge generated by the lectures, in addition to the replication of information to third parties, possibly an increase in the number of women who learned about what endometriosis is. Conclusion: It was found that the application of informative lectures on signs and symptoms of endometriosis increased the level of knowledge of adolescents between 16 and 17 years of age in public school.

Hepatoprotective and anti-inflammatory effects of silibinin on experimental preeclampsia induced by L-NAME in rats.

AIMS: Inhibition of nitric oxide synthase with N-omega-nitro-l-arginine methyl ester (l-NAME) has been employed as an experimental model of human preeclampsia. This study determined the protective effect of silibinin, a flavonoid with anti-inflammatory and hepatoprotective properties on the deleterious effects observed in experimentally induced preeclampsia in rats. MAIN METHODS: Pregnant Wistar rats were treated during gestation (days 10-20) with l-NAME (70-80mg/kg/day) in drinking water or with l-NAME plus silibinin (100mg/kg/day, orally) starting at day 0, day 7 or day 14 of pregnancy. Systolic blood pressure was recorded from gestation days 0 to 21. A control group of pregnant non-treated rats was analyzed similarly. On day 21 the rats were euthanized and the following parameters were evaluated: proteinuria, platelet count, liver histopathology and reproductive outcome. Tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1ß), IL-6, IL-10 and interferon-gamma (IFN-γ) were determined in liver homogenate by enzyme immunoassay. KEY FINDINGS: In comparison with the l-NAME group the silibinin treatment reduced the values of systolic blood pressure, proteinuria, TNF-α, IL-1ß and IFN-γ in liver, normalized the platelet count and improved fetal outcomes. Histopathological lesions in liver of the l-NAME group showed intense mononuclear inflammatory infiltrate and thickening of muscle tunica of arterial vessel, mainly in the periportal area. Silibinin treatment induced attenuation of periportal inflammatory infiltrate, showing an association between inflammatory infiltrate and TNF-α, IL-1ß and IFN-γ levels in liver homogenate. SIGNIFICANCE: Silibinin administration to l-NAME-treated rats displays anti-inflammatory and immunomodulatory actions that may contribute to its hepatoprotective effects and improve reproductive outcomes in experimental preeclampsia.
