Disparities in hepatocellular carcinoma (HCC) incidence and survival have been observed between ethnic groups including African-Americans (AA) and European-Americans (EA). The evaluation of the changes in the levels of metabolites in samples stratified by race could provide a snapshot of ethnically diverse disease related pathways and identify reliable biomarkers. In this study, we considered AA and EA to investigate metabolites that may be associated with HCC in a race-specific manner. The levels of 46 metabolites in plasma samples, collected from patients recruited at MedStar Georgetown University Hospital, were analyzed by Agilent GC-qMS in selected ion monitoring (SIM) mode...

We developed a Rapid Diagnostic Test (RDT) kit for detecting IgG/IgM antibodies against Zika virus (ZIKV) using monoclonal antibodies to the envelope (E) and non-structural protein 1 (NS1) of ZIKV. These proteins were produced using baculovirus expression vector with Sf9 cells. Monoclonal antibodies J2G7 to NS1 and J5E1 to E protein were selected and conjugated with colloidal gold to produce the Zika IgG/IgM RDT kit (Zika RDT). Comparisons with ELISA, plaque reduction neutralization test (PRNT), and PCR were done to investigate the analytical sensitivity of Zika RDT, which resulted in 100% identical results...

BACKGROUND: Individuals coinfected with both hepatitis C virus (HCV) and HIV represent a unique and growing population of patients undergoing orthopaedic surgical procedures. Data regarding complications for HCV monoinfection or HIV monoinfection are robust, but there are no data available, to our knowledge, on patients who have both HCV and HIV infections. QUESTIONS/PURPOSES: We sought to determine whether patients with coinfection differed in terms of baseline demographics and comorbidity burden as compared with patients without coinfection and whether these potential differences were translated into varying levels of postoperative complications, mortality, and hospital readmission risk...

Effusion-based lymphoma (EBL) is a rare but distinct entity of large B-cell lymphoma in effusion without association with human herpes virus-8 (HHV-8). Spontaneous regression after pleurocentesis has been observed; but to our knowledge, there are no reports on the morphological and molecular features of subsequent aspirations in regressing cases. Here, we report the case of a 92-year-old male with chronic obstructive pulmonary disease, who presented with right pleural effusion. He had no human immunodeficiency virus, hepatitis B virus, or hepatitis C virus infection, and CT scans revealed no mass lesion...

BACKGROUND: Multiple antigen miniarrays used for detecting autoantibodies to tumor-associated antigens (TAAs) can be a useful approach for cancer detection and diagnosis. We here address a very specific question: might there be autoimmune responses to TAAs which precede clinical detection of hepatocellular carcinoma (HCC) in HBV and HCV chronic liver disease patients under continuous medical surveillance, and if so, could these anti-TAAs be added to the armamentarium of diagnostic tests? METHODS: We here examine the utility of a panel of 12 TAAs for the diagnosis of hepatocellular carcinoma (HCC)...

Hyperviscosity syndrome (HVS) develops most commonly in Waldenström's macroglobulinemia (WM) and multiple myeloma (MM). Plasmapheresis is the immediate therapy and very effective at relieving symptoms by removing paraprotein. The most commonly used replacement fluid is 4%-5% human albumin in physiologic saline. FFP may be used in patients with coagulation abnormalities. Plasmapheresis should be continued until acute symptoms abate. Hyperviscosity impairs the circulation in the retina and causes hemorrhages around the small retinal vessels...
