MiR-150-5p Overexpression in Triple-Negative Breast Cancer Contributes to the In Vitro Aggressiveness of This Breast Cancer Subtype. Cancers (Basel) 2022; 14:cancers14092156.

Abstract
Simple Summary Triple-negative breast cancer (TNBC) is a clinically aggressive type of breast cancer. MicroRNAs (miRNAs) are small molecules that regulate the expression of genes involved in tumor cell signaling. The miR-150-5p is frequently deregulated in cancer, with expression and mode of action varying according to the cancer type. In this study, we investigated the expression levels of miR-150-5p in TNBC, its association with clinical and pathological features of patients, and its role in modulating TNBC cell proliferation, migration, and drug resistance. Our results suggest that miR-150-5p is highly expressed in TNBC and that miR-150-5p expression levels are associated with tumor grade, patient survival, and ethnicity. Our findings also indicate that miR-150-5p contributes to the aggressive phenotypes of TNBC cells in vitro. Abstract MiR-150-5p is frequently deregulated in cancer, with expression and mode of action varying according to the tumor type. Here, we investigated the expression levels and role of miR-150-5p in the aggressive breast cancer subtype triple-negative breast cancer (TNBC). MiR-150-5p expression levels were analyzed in tissue samples from 113 patients with invasive breast cancer (56 TNBC and 57 non-TNBC) and 41 adjacent non-tumor tissues (ANT). Overexpression of miR-150-5p was observed in tumor tissues compared with ANT tissues and in TNBC compared with non-TNBC tissues. MiR-150-5p expression levels were significantly associated with high tumor grades and the Caucasian ethnicity. Interestingly, high miR-150-5p levels were associated with prolonged overall survival. Manipulation of miR-150-5p expression in TNBC cells modulated cell proliferation, clonogenicity, migration, and drug resistance. Manipulation of miR-150-5p expression also resulted in altered expression of its mRNA targets, including epithelial-to-mesenchymal transition markers, MYB, and members of the SRC pathway. These findings suggest that miR-150-5p is overexpressed in TNBC and contributes to the aggressiveness of TNBC cells in vitro.

Abstract
We assessed the quality of hand hygiene among healthcare workers at a pediatrics hospital in Rio de Janeiro, Brazil. Hand hygiene was performed in 491 (34%) of 1,455 opportunities. Of these hand hygiene events, correct performance was observed in only 173 (35%). Multivariate analysis revealed that correct performance of hand hygiene was associated with the use of an alcohol-based product and a lack of jewelry (for all events) and employment in an infirmary with a comparatively higher ratio of nurses to patients (for events involving nurses).

Abstract
Estudou-se a atividade da ceruloplasmina, adenosina desaminase (AD) e transaminases glutâmico oxalacética (TGO) e glutâmico pirúvica (TGP) na supra-renal de ratos normais e injetados previamente (24 horas antes) com uma injeção única, por via intraperitoneal, de ACTH em doses de 0,5 e 1,2 un. internacionais. observou-se uma elevação estatisticamente significativa das TGO e ceruloplasmina enquanto a AD sofria diminuição sensível em sua atividade.
