The associations between injury severity, posttraumatic stress disorder (PTSD), and development of chronic diseases, such as hypertension, among military service members are not understood. We sought to (1) estimate the prevalence and incidence of PTSD within a severely injured military cohort, (2) assess the association between the presence and chronicity of PTSD and hypertension, and (3) determine whether or not initial injury severity score and PTSD are independent risk factors for hypertension. Administrative and clinical databases were used to conduct a retrospective cohort study of 3846 US military casualties injured in the Iraq and Afghanistan conflicts between February 1, 2002, and February 1, 2011...

Background: Gastric cancer (GC) is a major cause of cancer deaths, especially in Eastern Asia. Current classification systems, including the WHO, Lauren, and TCGA, have clarified the pathological and molecular profiles of GC. However, these classifications lack an association with clinical outcome and guidance for medication selection. Objective: We aimed to identify a new immunoclassification for GC to better predict patient prognosis and aid in patient selection for immunotherapy...

Gastric carcinoma (GC) is one of the most aggressive cancers and the second leading cause of cancer death in the world. According to the Lauren classification, this adenocarcinoma is divided into two subtypes, intestinal and diffuse, which differ in their clinical, epidemiological and molecular features. Several studies have attempted to delineate the molecular signature of gastric cancer to develop new and non-invasive screening tests that improve diagnosis and lead to new treatment strategies. However, a consensus signature has not yet been identified for each condition...

A first molecular-based phylogeny is presented for the Laboulbeniomycetes, a group of ascomycete fungi that utilize arthropods for nutrition and/or dispersal. Morphological diversification and life-history evolution has made it difficult to resolve relationships within the group, and to identify close relatives. Here, we infer a preliminary phylogeny based on acquisition of 51 new SSU rDNA sequences, representing a total of 65 taxa. The results of this study demonstrate that Laboulbeniomycetes is monophyletic, and related to Sordariomycetes...

A new diagnostic paradigm has been proposed to better categorize causes of Metformin-Associated Lactic Acidosis (MALA). The diagnostic criteria defines a link between Metformin and lactic acidosis if lactate is >5mmol/L, Ph<7.35 and Metformin assay >5mg/L. Metformin assays are not readily available in emergency departments including nationwide Veteran's Affairs Hospitals; thereby making this proposed classification tool difficult to use in today's clinical practice. We describe a case report of a 45-year-old male, who took twice the amount of Metformin prescribed and presented with Metformin-induced lactic acidosis...

Accelerometers have been used to classify running patterns, but classification accuracy and computational load depends on signal segmentation and feature extraction. Stride-based segmentation relies on identifying gait events, a step avoided by using window-based segmentation. For each segment, discrete points can be extracted from the accelerometer signal, or advanced features can be computed. Therefore, the purpose of this study was to examine how different segmentation and feature extraction methods influence the accuracy and computational load of classifying running conditions...

Pheochromocytomas and paragangliomas (PCC/PGLs) are rare neuroendocrine tumors that are unusually diverse in metabolic profiles, in classes of molecular alterations and across a large number of altered genes. The Cancer Genome Atlas (TCGA) comprehensively profiled the molecular landscape of PCC/PGLs and identified novel genomic alterations and a new molecular classification of PCC/PGLs. In this review, we discuss the significant clinico-molecular findings of this integrated profiling study. We then review the molecular data of the TCGA cohort centering around known markers of sympathoadrenal cell lineage to better understand chromaffin cell biology...

As one form of branched chain amino-acid transaminase(BCAT) enzymes, It has been found that up-regulation of BCAT1 is associated with poor prognosis in numerous types of tumors, but studies on the role of BCAT1 expression in gastric cancer(GC) are rare. The aim of this study was to detect BCAT1 expression in (GC) and to analyze its association with prognosis of GC patients. Microarray experiments were performed on the Affymetrix U133 plus 2.0 GeneChip Array. The protein and mRNA levels of BCAT1 were validated by immunohistochemistry (IHC) and Real-Time quantitative PCR (RT-qPCR) in GC tissues and adjacent noncancerous tissues (ANCT)...

In this study, we investigated the role of Fat atypical cadherin 4 (FAT4) in gastric cancer (GC) progression. Immunohistochemical analysis showed lower FAT4 expression in tumor tissues from GC patients than in normal gastric epithelium. Lower FAT4 expression was associated with poor prognosis, tumor size and invasion, and lymph node and distant metastases. Multivariate analysis showed that TNM stage, lymph node and distant metastases, Lauren classification, and FAT4 expression were independent prognostic factors in GC...

PURPOSE: We sought to evaluate the association of prolonged elevated heart rate (peHR) with survival in acutely ill patients. METHODS: We used a large observational intensive care unit (ICU) database (Multiparameter Intelligent Monitoring in Intensive Care III [MIMIC-III]), where frequent heart rate measurements were available. The peHR was defined as a heart rate >100 beats/min in 11 of 12 consecutive hours. The outcome was survival status at 90 days. We collected heart rates, disease severity (simplified acute physiology scores [SAPS II]), comorbidities (Charlson scores), and International Classification of Diseases (ICD) diagnosis information in 31 513 patients from the MIMIC-III ICU database...

The relationship between vascular endothelial growth factor gene polymorphism and gastric cancer risk and its development, prognosis, and survival are still being debated. This meta-analysis was performed to assess these relationships. The association reports were identified from PubMed, Embase, Cochrane Library, and CBM-disc (China Biological Medicine Database), and eligible studies were included and calculated using the meta-analysis method. VEGF+936C/T, VEGF+405 G>C, VEGF-460 T>C, VEGF-1498 T>C, and VEGF-2578 C>A gene polymorphisms were found to be unassociated with gastric cancer risk for the overall population in this meta-analysis, whereas the VEGF-634 G>C GG genotype was associated with gastric cancer risk in the overall population...
