- Lifestyles and surveillance of sexual and reproductive women’s healthPublication . Ferreira, M.; Ferreira, S.; Ferreira, N.; Andrade, J.; Chaves, C.; Duarte, J.Abstract: Background: The epidemic increase of diseases is closely related to lifestyle changes. The low adhesion to breast self-examination and cervical cytology hinders prevention and early diagnosis during the asymptomatic state of two silent diseases, with nonspecific symptoms that are a major cause of death by cancer in the Portuguese female population. Objectives: To analyze the influence of sociodemographic variables and lifestyles in the surveillance of sexual and reproductive health of Portuguese women. Methods: Quantitative, non-experimental, correlational and cross-sectional study, conducted with a non-probabilistic convenience sample of 522 women aged between 18 and 67 years old, who applied the questionnaires about Breast self-examination, Knowledge about cervical cancer and the Inventory "My Lifestyle" (Ribeiro, 1993. Results: The average age of women is 38.89 years old. Women aged 31-37 years old (28.6%), Portuguese (99.1%), cohabiting with a partner and / or child (74.0%), with an active employment status (67 5%), residing in urban areas (55.8%) with higher education and attending family planning consultations have better lifestyles, without statistical significance (F = 0.016, p = 0.899). Conclusions: Healthy behaviors and lifestyles are crucial to good overall health. Adhesion to surveillance of sexual and reproductive women’s health is influenced by several factors, including the place of residence, employment status and lifestyles. These variables must be considered by health professionals when planning periodic screenings.
- Sex differences in bladder cancer chemoprevention by green teaPublication . Videira-Henriques, A.; Ferreira, S.; Almeida, L.; Arantes-Rodrigues, R.; Vasconcelos-Nóbrega, C.; Vala, Helena; Colaço, A.; Oliveira, P. A.; Oliveira, P. A .Background: In bladder cancer prevention studies, is important to investigate how both sexes respond to different agents. The purpose of this experiment was to evaluate the protective effect of green tea consumption in bladder cancer induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) in Mus musculus of both sexes. Methods: 21 male and 20 female mice were randomly assigned into three groups (I-Green tea+BBN, II-BBN and III-Green tea), in both sexes. The green tea was prepared daily at a concentration of 0,5% during 20 weeks and BBN was administrated by gavage in mean doses of 7,25 mg/mouse for week, through 10 weeks. After 20 weeks, animals were sacrificed and all bladders were collected for histological study. Results: In males, the group that showed a higher incidence of lesions was BBN + Green tea group. In females, the BBN group was the one with more histological lesions. A higher incidence of inflammatory infiltrate was observed in group exposed to BBN, followed the BBN+Green tea group, and finally green tea group. These observations were consistent for both sexes. Conclusions: We can conclude that green tea has a potential prevention effect of bladder cancer in females. The histological alterations were probably due to the influence of green tea in the metabolism acceleration of females and the protective effect of estrogens.
