OBJECTIVE: Ultrasound-guided fine-needle aspiration cytology (USG-FNAC) is used for the detection of axillary lymph node (ALN) metastasis in patients with breast carcinoma (BC). US findings have a good diagnostic accuracy with high sensitivity and specificity. The aim of this study is to correlate the detection of ALN metastases on US with FNAC in BC patients. STUDY DESIGN: In 75 BC patients, over a period of 9 months (January to September 2017), the size, cortical thickness (CT), presence or absence of hilar fat, and length/width ratio of ALN on US were reviewed and correlated with FNAC findings...

In this issue of Structure, Haddad et al. (2018) solve the high-resolution trimeric crystal structure of human COMPASS-like components Dpy-30 and Ash2L (2:1) to unravel an uncharacterized interaction surface required for competent H3K4 methylation in cells and clarify Dpy-30's role in the allosteric regulation of KMT2 enzymes.

PURPOSE: In the process of developing an evidence-based decision dashboard to support treatment decisions for patients with newly diagnosed prostate cancer, we found that the clinical evidence base is insufficient to provide high-quality comparative outcome data. We therefore sought to determine if clinically acceptable outcome estimates could be created using a modified version of the Sheffield Elicitation Framework (SHELF), a formal method for eliciting judgments regarding probability distributions of expected decision outcomes...

Background: The BRCA1-associated protein-1 (BAP1) tumor predisposition syndrome (BAP1-TPDS) is a hereditary tumor syndrome caused by germline pathogenic variants in BAP1 encoding a tumor suppressor associated with uveal melanoma, mesothelioma, cutaneous melanoma, renal cell carcinoma, and cutaneous BAP1-inactivated melanocytic tumors. However, the full spectrum of tumors associated with the syndrome is yet to be determined. Improved understanding of the BAP1-TPDS is crucial for appropriate clinical management of BAP1 germline variant carriers and their families, including genetic counseling and surveillance for new tumors...

CRISPR (clustered regularly interspaced short palindromic repeat) endonucleases are at the forefront of biotechnology, synthetic biology and gene editing. Methods for controlling enzyme properties promise to improve existing applications and enable new technologies. CRISPR enzymes rely on RNA cofactors to guide catalysis. Therefore, chemical modification of the guide RNA can be used to characterize structure-activity relationships within CRISPR ribonucleoprotein (RNP) enzymes and identify compatible chemistries for controlling activity...

Objective: To quantify how stress related to use of health information technology (HIT) predicts burnout among physicians. Methods: All 4197 practicing physicians in Rhode Island were surveyed in 2017 on their HIT use. Our main outcome was self-reported burnout. The presence of HIT-related stress was defined by report of at least 1 of the following: poor/marginal time for documentation, moderately high/excessive time spent on the electronic health record (EHR) at home, and agreement that using an EHR adds to daily frustration...

OBJECTIVE: To know the main health guidance needs of family members of children with sickle cell disease. METHOD: Qualitative research, developed in a pediatric reference hospital of Ceará State, between April and May 2017, through the participation of 12 family members of children with sickle cell disease. The data were collected through semi-structured interviewees and analyzed according to the Bardin's Thematic Categorical Analysis. RESULTS: The relatives had divergent opinions about what this pathology would be and expressed the expectation of being broadly guided, from general information (signs and symptoms) to more complex ones about the disease, including major complications and ways of preventing them...

The aim of this study was to evaluate the safety and efficacy of using autologous, micro-fractured, minimally manipulated adipose tissue in patients with refractory knee osteoarthritis (OA). A total of 17 subjects (26 knees) with a median age of 72 years (range: 54-78 years) and a history of knee OA (Kellgren-Lawrence, grade of 3 or 4) underwent treatment with ultrasound-guided injection of micro-fractured adipose tissue. Micro-fractured fat was obtained using a minimal manipulation technique in a closed system (Lipogems), without the addition of enzymes or any other additives...

BACKGROUND: The knowledge of circulating HCV genotypes and subtypes in a country is crucial to guide antiviral therapy and to understand local epidemiology. Studies investigating circulating HCV genotypes and their trends have been conducted in Belgium. However they are outdated, lack nationwide representativeness or were not conducted in the general population. METHODS: In order to determine the distribution of different circulating HCV genotypes in Belgium, we conducted a multicentre study with all the 19 Belgian laboratories performing reimbursed HCV genotyping assays...

Coculture of mesenchymal stem cells (MSCs) and vascular endothelial cells (ECs) in vitro leads to the formation of a capillary-like reticular structure by ECs, which has great potential as a better substitute for artificial blood vessels in terms of stability and functionality. To investigate the mechanisms of the early neovascularization induced by MSCs, we analyzed the kinematic features of the motion of ECs and concluded that the dynamic interaction between cells and the extracellular matrix would reveal the capillary-like structure formation...

The complete excision of glioblastomas with maximal retention of surrounding normal tissues can significantly improve patient prognosis. Near-infrared fluorescence (NIRF) optical imaging of the tumor vasculature offers a non-invasive method for detection of early-stage glioblastoma and efficient monitoring of therapeutic responses. The aim of this study was to develop a novel NIRF imaging probe as a visualization tool for image-guided surgical resection of orthotopic glioblastoma. In this study, Cy5.5-RKL, Cy5...

Alboflavusins (AFNs) are a group of cyclohexapeptides with moderate antibacterial and antitumor activities from Streptomyces alboflavus sp. 313. In vivo and in vitro studies proposed that AFNs are biosynthesized by a non-ribosomal peptide synthetase machinery, and the 6-Cl-L-Trp precursor is supplied by a tryptophan halogenase gene locating outside the afn gene cluster. Guided by the structure-activity relationship knowledge about the AFN-like cyclohexapeptides, two Dimeric AFNs (Di-AFNs) with regiospecific biaryl linkages were designed and generated biotechnologically by expressing the P450 gene hmtS or clpS in S...
