Liver damage is a common manifestation and can be life-threatening in adult-onset Still's disease (AOSD), an autoinflammatory disease. The hallmark of AOSD is activation of neutrophils, whose infiltration in liver is suspected to promote tissue injury. Here we aimed to identify a candidate biomarker and to validate its association with liver damage in AOSD.
Transcriptome analysis of neutrophils from treatment-naïve active AOSD patients and healthy donors was performed. Lipocalin-2 (LCN2) expression was assessed in neutrophils, plasma and liver biopsies of AOSD. The correlations of LCN2 with different variables and its ability to identify liver damage from AOSD patients were analysed.
LCN2, a novel biomarker in hepatic inflammation, was found to be upregulated in AOSD neutrophils by RNA sequencing and confirmed at the mRNA and protein levels. Plasma levels of LCN2 were significantly higher in AOSD patients than healthy controls, RA and SLE patients. Plasma LCN2 levels were closely correlated with inflammatory markers, systemic score, HScore and cytokines. Moreover, LCN2 levels were increased in active AOSD with liver involvement and independently associated with liver dysfunction. Enhanced expression of LCN2 was detected in liver biopsies from three patients with ongoing liver injury. Furthermore, the area under the curve value of LCN2 for identifying AOSD with liver injury from other liver diseases was 0.9694.
Our results reveal that neutrophils-derived LCN2 is higher in plasma and liver tissue in AOSD patients than in healthy controls, and it could serve as a potent biomarker for identifying AOSD with systemic inflammation, especially liver damage caused by hyperinflammation.

Currently, neuropathological diagnosis relies on biopsy of tumor tissue and surgical intervention. Protein Tyrosine Kinase inhibitor There is a great clinical need for less invasive methods to molecularly characterize the tumor and allow for more reliable monitoring of patients during treatment and to identify patients that might potentially benefit from targeted therapies, particularly in the setting where diagnostic tissue cannot be safely obtained. In this literature review, we highlight recent studies that describe the use of circulating tumor DNA, circulating tumor cells, circulating RNA and microRNA, and extracellular vesicles as strategies to develop liquid biopsies in pediatric central nervous system tumors. Liquid biomarkers have been demonstrated using plasma, urine, and cerebrospinal fluid. The use of liquid biopsies to help guide diagnosis, determine treatment response, and analyze mechanisms of treatment resistance is foreseeable in the future. Continued efforts to improve signal detection and standardize liquid biopsy procedures are needed for clinical application.College-age women are disproportionately at risk of experiencing sexual assault. Sexual assault causes tremendous psychological distress for survivors. Therefore, it is imperative to understand the perceptions that affect the perpetration of sexual assault. One of those potential factors is how college students conceptualize and define sexual assault. The current qualitative study demonstrated that college students do not have consistent images of sexual assault and often rely on their own perceptions and experiences to define it. Creating and providing a standard of sexual assault based on the reality of college students can provide a foundation for creating effective prevention strategies.The aim of this study is to describe outcomes of esophageal cancer surgery in a quaternary upper gastrointestinal (GI) center in Athens during the era of the Greek financial crisis. We performed a retrospective analysis of patients that underwent esophagectomy for esophageal or gastroesophageal junction (GEJ) cancer at an upper GI unit of the University of Athens, during the period January 2004-June 2019. Time-to-event analyses were performed to explore trends in survival and recurrence. A total of 146 patients were identified. Nearly half of the patients (49.3%) underwent surgery during the last 4 years of the financial crisis (2015-2018). Mean age at the time of surgery was 62.3 ± 10.3 years, and patients did not present at older ages during the recession (P = 0.50). Most patients were stage III at the time of surgery both prior to the recession (35%) and during the financial crisis (39.8%, P = 0.17). Ivor-Lewis was the most commonly performed procedure (67.1%) across all eras (P = 0.06). Gastric conduit wa = 0.91). The establishment of capital controls also had no impact on recurrence (P = 0.18) and survival (P = 0.94). Austerity measures during the Greek financial crisis did not influence long-term esophageal cancer outcomes. Therefore, achieving international standards in esophagectomy may be possible in resource-limited countries when centralizing care.
The Uniformed Services University of the Health Sciences coordinates a 2-week Summer Operational Experience (SOE) during the first year of medical school. The SOE aims to provide students with operational context and enhance familiarity with service-specific operational environments, the services' medical department capabilities, and/or general warfighter skills. One overarching goal of the SOE is to provide an experience that may motivate students to pursue an operational medicine assignment at some point in their military career. However, to date, little evaluation data have been collected regarding the effectiveness of the SOE in encouraging medical students to pursue operational medicine assignments. The purpose of this project was to develop and collect initial validity evidence for a survey instrument designed to assess various aspects of students' attitudes and behavioral intentions to pursue an operational medicine assignment at some point in their military career.
Using the theory of planned behavior as a framework, we developed a survey that focused on three distinct constructs attitude, subjective norms, and perceived behavioral control.
