e S100 protein for that purpose. Indeed, for any high-grade sinonasal tumor, pathologists must have a low threshold for utilizing additional markers to exclude the possibility of SNM.Shared genetic factors contribute to the high degree of comorbidity among externalizing problems (e.g. substance use and antisocial behavior). We leverage this common genetic etiology to identify genetic influences externalizing problems in participants from the Collaborative Study on the Genetics of Alcoholism (European ancestry = 7568; African ancestry = 3274). We performed a family-based genome-wide association study (GWAS) on externalizing scores derived from criterion counts of five DSM disorders (alcohol dependence, alcohol abuse, illicit drug dependence, illicit drug abuse, and either antisocial personality disorder or conduct disorder). We meta analyzed these results with a similar measure of externalizing in an independent sample, Spit for Science (combined sample N = 15,112). We did not discover any robust genome-wide significant signals. Polygenic scores derived from the ancestry-specific GWAS summary statistics predicted externalizing problems in an independent European ancestry sample, but not in those of African ancestry. However, these PRS were no longer significant after adjusting for multiple testing. Larger samples with deep phenotyping are necessary for the discovery of SNPs related to externalizing problems.Tumor metastasis and chemoresistance are the main causes of treatment failure and high mortality in hepatocellular carcinoma (HCC). Therefore, it is critical to clarify the biological action and potential mechanisms in HCC cells to develop novel therapeutics. The regulator of chromosome condensation 2 (RCC2), a component of the chromosomal passenger complex, was shown to have important roles in tumor development and radio-chemotherapy resistance. However, its role in the aggressive phenotypes and cisplatin (DDP)-resistance of HCC is not known. Therefore, this study aimed to investigate the role of RCC2 in HCC pathogenesis. Interestingly, we found that RCC2 was upregulated in HCC patient specimens and HCC cell lines and was correlated with the pathological grade of HCC. To evaluate the function of RCC2 in HCC cell, lentivirus vector-based shRNAs were transfected into HCC cells. Silencing RCC2 inhibited the HCC cell proliferation, migration, invasion, and increased the apoptosis rate upon DDP treatment. read more Further analysis showed that RCC2-mediated downregulation of the expression of survival proteins occurred via the AKT and Bcl2 pathways. Our results suggest that RCC2 might act as an oncogenic protein promoting metastatic behaviors and cisplatin resistance in HCC cells, and thereby could be a potential prognostic biomarker and therapeutic target for HCC.BACKGROUND Echocardiography is increasingly performed among septic patients as a routine part of evaluation and management in the intensive care unit (ICU). The rate of unanticipated critical findings (e.g., severe left or right ventricular dysfunction or pericardial tamponade) on such echocardiograms is unknown. We evaluated a retrospective cohort of septic ICU patients in whom transthoracic echocardiography was performed as a routine part of sepsis management. In addition to identifying critical findings, we defined whether each critical finding was anticipated, and whether the clinical team responded to the critical finding. The primary outcome was rate of unanticipated critical findings, which we hypothesized would occur in fewer than 5% of patients. We also performed an exploratory analysis of the association between unanticipated critical finding and mortality, controlling for severity of illness. RESULTS We studied 393 patients. Unanticipated critical findings were identified in 5% (95% CI 3-7%) of patients (n = 20). Among the 20 patients with unanticipated critical findings, a response to the unanticipated critical finding was identified in 12 (60%) patients. An unanticipated critical finding was not significantly associated with 28-day mortality when controlling for admission APACHE II (p = 0.27). CONCLUSIONS Unanticipated critical findings on echocardiograms in septic ICU patients are uncommon. The potential therapeutic relevance of echocardiography to sepsis is more likely related to hemodynamic management than to traditional cardiac diagnoses. Research studies that employ blinded echocardiograms in septic patients may anticipate unblinding for critical findings approximately 1 in every 20 echocardiograms.OBJECTIVE We sought to evaluate the relationship between acute liver injury (ALI) and statins utilizing the Veterans Affairs Informatics and Computing Infrastructure (VINCI) database. METHODS This retrospective cohort study, spanning January 2000-December 2018, compared ALI (aminotransferase > 200 U/L, severe ALI, and hospitalization with ALI) in statin users and non-users among uninfected, hepatitis C virus (HCV) mono-infected, human immunodeficiency virus (HIV)/HCV co-infected, and HIV mono-infected veterans within 18 months. We estimated adjusted Cox proportional hazards models comparing statin users and non-users and comparing statin intensity level with non-use; and estimate Cox proportional hazards models utilizing time-dependent coding of statin intensity. Adjusted models included restricted cubic splines of the propensity score as an adjustment variable. RESULTS From a total of 166,439 patients who met the study criteria, statin initiators were older, had higher values of body mass index, higher values of low-density lipoprotein cholesterol and triglycerides, and lower values of high-density lipoprotein cholesterol. HCV mono-infected and HIV/HCV co-infected cohorts had the highest rates of ALI, and statin users had lower rates across all outcomes of ALI compared with non-users in unadjusted analysis. Statin use is associated with a lower risk of all ALI outcomes compared with non-users. Patients on a high intensity are not associated with a statistically significant increase in risk for any ALI outcome. For each additional 30 days of treatment, there was a reduced risk of any ALI outcome across all cohorts. CONCLUSIONS Statin initiators had a lower risk of any ALI outcome compared with non-users within 18 months regardless of HIV and/or HCV status.
