BACKGROUND   Postoperative infections are frequent complications after liver resection and have significant impact on length of stay, morbidity and mortality. Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, accounting for 38% of all such infections. OBJECTIVES   This study aimed to identify predictors of SSI and(More)
OBJECTIVE To determine outcomes in patients undergoing liver transplantation (LT) for metastatic neuroendocrine tumors (NETs). DESIGN Retrospective analysis. SETTING University of Kentucky Medical Center. PATIENTS Patients undergoing LT performed for NET metastases from October 1, 1988, through January 31, 2008, were analyzed using the United Network(More)
BACKGROUND To determine factors associated with outcomes and microvascular invasion (MVI) in patients undergoing liver transplantation (LT) for hepatocellular carcinoma (HCC). METHODS Between July 1996 and August 2008 at the Universities of Kentucky or Tennessee, LT recipients were retrospectively analysed. RESULTS One hundred and one patients had HCC(More)
Neuroendocrine tumors (NET) are a heterogeneous group of cancers, with indolent behavior. The most common primary origin is the gastro-intestinal tract but can also appear in the lungs, kidneys, adrenals, ovaries and other organs. In general, NET is usually discovered in the metastatic phase (40%-80%). The liver is the most common organ involved when(More)
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver accounting for 7% of all cancers worldwide. Most cases of HCC develop within an established background of chronic liver disease. For that reason, liver resection is only possible in selected patients. Liver transplantation has become the treatment of choice in patients with(More)
BACKGROUND Aberrant Ras/Raf/MAPK and PI3K/AKT/mTOR signaling pathways are found in hepatocellular carcinoma (HCC). This study reports how sorafenib (a multi-kinase inhibitor) and PI-103 (a dual PI3K/mTOR inhibitor) alone and in combination inhibit the proliferation of the HCC cell line, Huh7. MATERIALS AND METHODS Huh7 proliferation was assayed by(More)
Curcumin is a multi-functional and pharmacologically safe natural agent. Used as a food additive for centuries, it also has anti-inflammatory, anti-virus and anti-tumor properties. We previously found that it is a potent inhibitor of cyclosporin A (CsA)-resistant T-cell co-stimulation pathway. It inhibits mitogen-stimulated lymphocyte proliferation,(More)
Although combination simeprevir (SIM) plus sofosbuvir (SOF) is an approved regimen for genotype 1 chronic hepatitis C virus (HCV), data regarding its safety and efficacy in liver transplant recipients remain limited. A multicenter retrospective study was performed to determine the efficacy and tolerability of a 12-week regimen of SIM/SOF with or without(More)
Tremor is a common side effect of tacrolimus correlated with peak-dose drug concentration. LCPT, a novel, once-daily, extended-release formulation of tacrolimus, has a reduced Cmax with comparable AUC exposure, requiring a ~30% dose reduction vs. immediate-release tacrolimus. In this phase 3b study, kidney transplant recipients (KTR) on a stable dose of(More)
