Background: Breast cancer (BC) is the one of the most common cancers in women. It is also a leading cause of death. Unfortunately, some patients initially present with distant metastases and are diagnosed with stage IV disease that is nearly always, by then, incurable. This retrospective analysis investigated the risk factors for stage IV BC that may underlie such late presentation. Materials and Methods: In all, 916 patients with BC who visited the medical oncology polyclinic of eight different centres in Turkeybetween December 2011 and January 2013 were analysed. Results: A total of 115 patients (12.6%) presented with stage IV disease. In univariate analysis; to comparing these with patients at other stages, no statistical difference was found for median diagnosis age or age at menarche (p=0.611 and p=0.820), whereas age at menopause and age at first live birth were significant (p=0.018 and p=0.003). No difference was detected in terms of accompanying diseases, use of oral contraceptives and hormone replacement therapy, smoking, alcohol consumption and the rate of family history of BC between the patients (p=0.655, p=0.389, p=0.762, p=0.813, p=0.229, p=0.737). However, screening methods were employed less often, the rate of illiteracy was higher, and the rate of other cancers was higher in patients with stage IV BC (p=0.022, p=0.022, p=0.018). No statistical difference was observed between the patients in terms of tumour histopathology, and status of oestrogen receptor, progesterone receptor, or human epidermal growth factor-2 receptor (p=0.389, p=0.326, p=0.949, p=0.326). Grade 3 tumours were more frequent in patients with stage IV disease (p<0.001). On multivariate analysis, risk factors for stage IV breast cancer at the time of presentation were found to be age at first live birth and educational level (p=0.003 and p=0.047). Conclusions: Efforts should be made to perform mammography scans, in particular, at regular intervals through national training programs for all women, particularly those with family histories of breast and other types of cancer, and to establish early diagnosis of BC long before it proceeds to stage IV. Additionally, women's education had better be upgraded. In order to make women aware of BC, national education-programmes must be organised.

Bisphenol A, an everywhere chemical, is applied as a plasticizer in polycarbonate plastics, which often used in our everyday products and in epoxy resins as protective coatings and linings for food and beverage cans for decades. Human exposure to BPA may lead to adverse effects by interfering with oestrogen receptors. Our present study was conducted to investigate the protective effects of selenium (Se) and vitamin E (Vit E) on BPA-induced damage in the liver of male rats. Animals were randomly divided into four groups: the first group received olive oil and served as control. The second group received both (Se + Vit E) (0.5 mg/kg diet; 100 mg/kg of diet). The third one treated orally by (10 mg/kg b.w.) of BPA. The last group received (Se + Vit E) (0.5 mg/kg diet; 100 mg/kg of diet) concomitantly with (10 mg/kg b.w.) BPA. Exposure to BPA for three weeks engendered a hepatic disorder. An increased AST and ALT enzymatic activity was noticed in BPA-treated group as compared to other groups. Furthermore, a change in glucose, cholesterol, LDL-C, HDL-C, albumin, and bilirubin level was remarkable. Moreover, exposure to BPA increased malondialdehyde levels while reduced gluthatione content was decreased in the liver homogenate. A decrease in glutathione peroxidase, glutathione s-transferase and catalase activities was observed in the same group. Administration of selenium and vitamin E through the diet in BPA treated rats ameliorated the biochemical parameters cited above. In addition, an improvement in activities of liver enzymes was recorded. The histological findings confirmed the biochemical results. The model of this study that we employed characterized the relationships between BPA-induced hepatotoxicity and its alleviation by natural antioxidants like selenium and vitamin E.

본 연구의 목적은 생식기 기형의 대표적인 하위유형인 요도하열과 잠복고환 영유아와 양육자의 심리 사회적 특성을 탐색하는 것이다. 생후 6~38개월 요도하열(103명), 잠복고환(48명)을 대상으로 생식기 기형과 관련한 걱정과 사건 충격, 수치심을 탐색하였다. 이들을 정상통제군(131명) 양육자와 비교하여 영아의 기질과 양육자의 정신 건강, 양육자의 사회적 지지와 결혼 만족도, 양육 스트레스와 대처기제를 비교하였다. 결과, 요도하열군 모는 '배뇨와 신체기능'과 '출산 능력'을, 잠복고환 모는 '마취에 대한 부담'과 '출산 능력'을 가장 걱정하였다. 또 요도하열 모는 임상수준의 심리적 충격을 보고하였다. 정상군과의 비교에서, 요도하열 영아는 정상영아에 비해 부정적 정서가 높았고, 잠복고환 영아는 주의 전환성이 유의하게 낮았으며, 요도하열과 잠복고환 모는 정상군모보다 대인 예민성이 낮았다. 사회적 지지에서 세 집단 간 차이는 없었으나, 잠복고환 모는 정상군 모에 비해 원가족과의 갈등이 적다고 보고하였다. 요도하열과 잠복고환 모는 정상군 모보다 양육 스트레스 중 부모의 고통은 낮았고, 대처 전략을 많이 사용하였다. 양육 스트레스 총점이나 까다로운 자녀, 역기능적 상호작용에서는 집단 간 차이는 나타나지 않았다. 결과에 대해 임상적 함의와 연구적 함의를 논의하였다.
