RESUMO

INTRODUCTION: Breast cancer is the most common malignancy among women, and subtypes are mainly defined based on hormone receptors such as estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). The relationship between breast cancer subtypes and imaging features in mammography and sonography has been studied but the results are controversial. The purpose of this study was to determine the relationship between the hormonal receptor status of breast tumors and the radiologic feature of the tumors on mammography and sonography. METHODS: Eighty patients with breast cancer enrolled in this cross-sectional study. ER, PR, and HER2 determined by immunohistochemistry. Every patient underwent mammography and sonography before the biopsy. We evaluated the relationship between the hormonal receptor status and radiographic features of tumors on breast sonography and mammography. RESULTS: The majority of the patients (n=75 (93.8%)) were diagnosed with invasive ductal carcinoma (IDC). The mean and standard deviation of the age was 49 ± 9 years. There was no significant relationship between the hormonal receptor status and the sonographic margin and shape (P>0.05). However, PR (P=0.002) and ER (P=0.001) status were significantly correlated with posterior features on sonography. ER-positive patients were more likely to have indistinct or speculated masses on mammography (P=0.017). Irregular or oval masses on mammography were higher in patients with ER (p=0.032). CONCLUSION: There was a significant correlation between PR and ER status and posterior features on sonography. Positive ER was associated with indistinct or speculated masses on mammography, as well as irregular or oval masses.

RESUMO

CONTEXT: The pathogenesis of schizophrenia appears to be multifaceted. OBJECTIVE: The aim of this meta-analysis of studies that investigated blood and hair concentrations of trace elements in people diagnosed with schizophrenia was to determine whether levels of trace elements in patients with schizophrenia differ from those in healthy individuals. DATA SOURCES: The PubMed, Scopus, and Web of Science databases were searched to January 2018. STUDY SELECTION: Studies that compared concentrations of trace elements in patients with schizophrenia with those in healthy controls, in patients with schizophrenia under different treatment regimens, or in patients with schizophrenia at different stages of disease were included. DATA EXTRACTION: Data on study and sample characteristics and measures of trace elements were extracted. RESULTS: Thirty-nine studies with a total of 5151 participants were included. Meta-analysis of combined plasma and serum data showed higher levels of copper, lower levels of iron, and lower levels of zinc among patients with schizophrenia vs controls without schizophrenia. Subgroup analyses confirmed the following: higher levels of copper in plasma, in users of typical antipsychotic drugs, and in males; lower levels of zinc in serum, in patients in Asia, in drug-naive/drug-free patients, and in inpatients; lower levels of iron in serum, in patients in Asia, in drug-naive/drug-free patients, in patients on antipsychotic drugs, in inpatients, in patients with acute or newly diagnosed schizophrenia, in patients with chronic or previously diagnosed schizophrenia, and in males; and lower levels of manganese in plasma and in patients with chronic or previously diagnosed schizophrenia. CONCLUSIONS: This meta-analysis provides evidence of an excess of copper, along with deficiencies of zinc, iron, and manganese, in patients with schizophrenia.
