INTRODUCTION: Management of neuroendocrine liver metastasis (NELM) in the presence of extrahepatic disease (EHD) is controversial. We sought to examine outcomes of patients undergoing liver-directed therapy (resection, ablation, or both) for NELM in the presence of EHD using a large international cohort of patients. METHODS: 612 patients who underwent liver-directed therapy were identified from eight institutions. Postoperative outcomes, as well as and overall (OS) were compared among patients with and without EHD...

The first liver transplant in Saudi Arabia was performed in 1991; however, it was not until 1994 that the first structured liver transplant program was launched. Until 1997, all liver transplants in the Kingdom of Saudi Arabia (KSA) were deceased donor liver transplantations. Programs performing liver transplants needed the authorization of the Saudi Center for Organ Transplantation (SCOT), which provides the essential support for organ procurement and allocation as well as regulatory support for organ transplantation in the country...

Selectively depleting the pathogenic T cells is a fundamental strategy for the treatment of allograft rejection and autoimmune disease since it retains the overall immune function of host. The concept of killer artificial antigen-presenting cells (KaAPCs) has been developed by co-coupling peptide-major histocompatibility complex (pMHC) multimer and anti-Fas monoclonal antibody (mAb) onto the polymeric microparticles (MPs) to induce the apoptosis of antigen-specific T cells. But little information is available about its in vivo therapeutic potential and mechanism...

Cell death-inducing DFF45-like effector (CIDE) family proteins including Cidea, Cideb and Cidec/Fsp27 are expressed in many different tissues and are known as lipid droplet (LD)-and ER-associated proteins. Systematic analyses using genetically modified animal models have demonstrated that CIDE proteins play important roles in regulating various aspects of lipid homeostasis, including lipid storage, lipolysis and lipid secretion. Recent research in ours and other laboratories has revealed that CIDE proteins are crucial regulators of LD fusion and growth in the adipose tissue, liver, skin and mammary glands...

Liver biopsy is a valuable tool. Even though outpatient liver biopsies are routinely performed in adults, there are no clear recommendations on its safety and feasibility in children. We reviewed the records of children who underwent a percutaneous liver biopsy at our institution between January 2005 and June 2015. A total of 626 biopsies were performed on 497 patients (250 boys, median age 6 [0.2-19.3] years). Abnormal liver function tests for investigation 288 (46%) was the most common indication. Thirty (4...

PURPOSE: 1.5T gradient echo-based R2∗ estimates are standard-of-care for assessing liver iron concentration (LIC). Despite growing popularity of 3T, echo time (TE) limitations prevent 3T liver iron quantitation in the upper half of the clinical range (LIC ⪆20 mg/g). In this work, a 3D radial pulse sequence was assessed to double the dynamic range of 3T LIC estimates. THEORY AND METHODS: The minimum TE limits the dynamic range of pulse sequences to estimate R2∗...

Small for size and flow syndrome (SFSF) is one of the most challenging complications following extended hepatectomy (EH). After EH, hepatic artery flow decreases and portal vein flow increases per 100 gram remnant liver volume (RLV). This causes hypoxia followed by metabolic acidosis. A correlation between acidosis and post-hepatectomy liver failure has been postulated, but not studied systematically in a large animal model or clinical setting. In our study, we performed stepwise liver resections on nine pigs to defined SFSF limits as follows: step 1: segment II/III resection, step 2: segment IV resection, step 3: segment V/VIII resection (RLV: 75%, 50% and 25% respectively)...

Previous study has identified that the genetic variants in the human leukocyte antigen (HLA)-DP/DQ region were strongly associated with hepatitis B virus (HBV) infection. But their roles in liver function recovery after hepatic transplantation were still obscure. This study aimed to investigate whether HLA-DP/DQ polymorphisms were associated with post-transplant etiologies and prognosis in Chinese liver transplant recipients.A total of 144 liver transplant recipients were enrolled, which were divided into 2 groups according to the transplant etiology: HBV-related disease and non-HBV-related disease...

International guidelines suggest ultrasound surveillance for hepatocellular carcinoma (HCC) early diagnosis in liver cirrhosis (LC) patients, but 40% of nodules <2 cm escape detection. We investigated the existence of an ultrasound pattern indicating a higher risk of developing HCC in patients under surveillance. 359 patients with LC (Child-Pugh A-B8) underwent ultrasound screening (median follow-up 54 months, range 12-90 months), liver function tests, alpha-fetoprotein assay, and portal hypertension evaluation...

Previously, we have found that intracellular calcium homeostasis is altered in platelets from an experimental model of liver cirrhosis, the bile-duct ligated (BDL) rat; these alterations are compatible with the existence of a hypercoagulable state and related to an enhanced intracellular calcium release evoked by thrombin and an increased amount of calcium stored in the intracellular organelles. In the present study we have investigated the role of bile acids in those alterations of the BDL cirrhotic model...

Trastuzumab with chemotherapy improves clinical outcomes in patients with human epidermal growth factor receptor 2 (HER2)-positive esophagogastric adenocarcinoma (EGA). Despite the therapeutic benefit, responses are rarely complete and the majority of patients develop progression. This is the first report evaluating (89)Zr-trastuzumab in HER2-positive EGA in which we evaluate the safety, pharmacokinetics, biodistribution, and dosimetry. Methods: Trastuzumab was conjugated with deferoxamine and radiolabeled with (89)Zr...

In this study, a multicomponent nanodiamonds (NDs)-based targeting drug delivery system, cetuximab-NDs-cisplatin bioconjugate, combining both specific targeting and enhanced therapeutic efficacy capabilities, is developed and characterized. The specific targeting ability of cetuximab-NDs-cisplatin system on human liver hepatocellular carcinoma (HepG2) cells is evaluated through epidermal growth factor receptor (EGFR) blocking experiments, since EGFR is over-expressed on HepG2 cell membrane. Besides, cytotoxic evaluation confirms that cetuximab-NDs-cisplatin system could significantly inhibit the growth of HepG2 cells, and the therapeutic activity of this system is proven to be better than that of both nonspecific NDs-cisplatin conjugate and specific EGF-NDs-cisplatin conjugate...

Background Dutasteride has been successfully used in treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). However, dutasteride inhibits 5α-reductase type 1 and type 2 enzymes and may compromises glucocorticoids and androgen metabolism and alters metabolic function resulting in undesirable metabolic and sexual adverse side effects. Aim The aim of this study was to investigate the long-term adverse effects of dutasteride therapy in men with BPH on: i) blood glucose, ii) glycated hemoglobin (HbA1c), iii) low density lipoprotein-cholesterol (LDL-C); high density lipoprotein-cholesterol (HDL-C) and total cholesterol (TC), iv) testosterone (T), v) liver alanine and aspartate aminotransferases (ALT and AST) and vi) erectile dysfunction (ED)...
