The profiles correspond to increasing regulatory complexity, and subsequent profiles are modeled using increasing numbers of events. Data were warehoused in a Labkey system (Labkey, Inc., Seattle, WA). Primary data are available in accord with proposed Minimum Information About a Microarray Experiment standards (http://viromics.washington.edu). Also, data are available from the Metadata for Architectural Contents in Europe

database (http://mace.ihes.fr) using an accession number (2491581318). We identified 57 chronic HCV patients undergoing OLT at the UWMC and obtained core needle biopsies from various selleck kinase inhibitor time points post-OLT (Fig. 1). We grouped patients by post-OLT clinical outcome. Of 57 patients, 14 (25%) developed an adverse clinical outcome post-OLT (Table 1). After classifying our control, uninfected normal pool (UNP) of liver tissue, as group 1 (G1), we designated 43 HCV patients with no adverse clinical outcome as group 2 (G2). Three adverse clinical outcomes were defined for patient grouping. check details We first determined the patients’ most recent Batts-Ludwig stage of hepatic fibrosis by having one pathologist

stage the most recent biopsy before June 1, 2009, when we stopped collecting clinical information on the cohort for this study. We identified 4 patients with most recent biopsies at stage 3-4 and designated them as group 3 (G3). We also determined whether patients presented clinical symptoms of cirrhosis (e.g., portal hypertension, encephalopathy, ascites, until and bleeding esophageal

varices) and identified 3 patients, designated as group 4 (G4). Finally, we identified 7 HCV patients who died or underwent retransplantation resulting from graft failure, designated as group 5 (G5). All patients in G4 and G5 also developed stage 3-4 fibrosis before clinical cirrhosis or death/retransplantation. We confirmed that no patients demonstrated evidence of stage 3-4 fibrosis or symptoms of cirrhosis at the time the samples were collected. Therefore, gene-expression changes determined by our analysis to be significantly associated with severe liver injury were identified from samples taken before clinical or histological evidence of disease progression. We also divided the 111 liver biopsy specimens based on time post-OLT sampling (Fig. 1A). The relative heterogeneity of both timing of post-transplant biopsies from patients of this cohort and pathological phenotypes displayed by the different patients in the cohort (Fig. 1A) required particular attention during data analysis. Clinical annotation defined disease categories (G2-G5), and samples were further subdivided into time categories (i.e., early, intermediate, or late). These intervals were based on HCV reinfection kinetics and spreading in the donor organ and homogeneity of sample distribution. Nonprogressors (G2) also encompassed samples beyond the 2-year follow-up period of the severe liver disease groups (Fig. 1B).

pathophysiology of Irritable bowel syndrome (IBS) remains unclear, recent findings suggest that immunological imbalance in the intestine contributes to the development of the condition. Dendritic cells (DCs) are likely to play a pivotal role in the regulation of mucosal immune responses. This study tested the hypothesis that the characteristic of intestinal DCs changed in the development of a IBS rat model, which induced the visceral hyperalgesia in IBS through the activation of the mucosal immune system. Methods: IBS rat model was established by combining colorectal distention with restraint stress, which underwent abdominal withdrawal reflex (AWR) to evaluate visceral sensitivity. Surface marker of intestine DCs was analyzed by immunohistochemistry. Toluidine blue staining was used to determine the number of mast cells (MCs), electron microscopy was used to observe the degranulated

colonic MCs. Expression of interleukin-4 and interleukin-9 in colonic mucosa were measured by enzyme-linked immunosorbent assay (ELISA), and expression of PAR-2 was measured by western blot. Mesenteric lymph node DCs(MLNDCs),

INCB024360 splenic CD4+/CD8+Tcells were isolated and purified by magnetic label-based technique. Cytokine production of the MLNDCs cocultured with CD4+ or CD8+T cells was determined. Results: Visceral sensitivity was significantily higher in IBS group (p < 0.05). Surface marker CD103 was increased in IBS group as well as the number of colonic MCs (p < 0.05). Expression of PAR-2, IL-4 and IL-9 in colonic mucosa was higher than that in control group (p < 0.05). Cocultured MLNDCs with CD4+ T cells showed a predominant IL-4 secretion in the IBS group (p < 0.05), the secretion of IL-9 was related with CD8 + Tcells. Conclusion: The hypothesis was supported that the increased DCs in colon find more stimulated CD4+ T cells to secrete high level of cytokines IL-4, which lead to mast cells degranulation, resulting in the generation of visceral hypersensitivity in IBS rats.

Because of differences in clinical manifestations of ischemic bowel disease, non-specific in the early stages of the disease, or in patients with mild symptoms, clinical diagnosis is difficult and the high rate of misdiagnosis.

Ethanol increases the abundance of CYP2E1 in the liver largely by preventing its proteolysis.1 CYP2E1, which exhibits a high rate of NADPH oxidase activity even in the absence of substrate, reduces molecular oxygen to superoxide. Superoxide is converted to H2O2 and peroxynitrite, both of which generate other types of ROS such as lipid peroxides. Given the location of CYP2E1 at the cytosolic side of the ER membrane, ROS production Opaganib cost by this enzyme must also be localized to the outside surface of the ER, where we have now shown a large proportion of Prx I is also found. Prx I is therefore likely preferentially

engaged in the reduction of ROS produced by CYP2E1 and becomes hyperoxidized (Fig. 7). The preferential hyperoxidation of Prx I occurs despite the fact that both Prx I and II are cytosolic proteins and that Prx II is more prone to hyperoxidation than is Prx I

in most cell types.20 In addition to inducing the expression of Srx in the liver, ethanol feeding elicited the translocation of some Srx molecules to microsomes. However, the capacity of Srx located near the surface of the ER was not sufficient to fully counteract the hyperoxidation of Prx I, with consequent accumulation of a small amount of Prx I-SO2. Proteome analysis identified Prx I (but not other Prxs) among the many oxidatively damaged (hyperoxidized or carbonylated) proteins in the liver of ethanol-fed rats,35, 36 indicative of the proximity of Prx I to the ROS source. Ethanol feeding increases the production of ROS in mitochondria,4, 28, 30 with

this effect likely resulting in Prx III hyperoxidation and Talazoparib datasheet the translocation of Srx into mitochondria.23 Our failure to detect Prx III-SO2 in the liver of ethanol-fed wildtype mice suggests that the capacity of mitochondrial Srx is sufficient to counteract the hyperoxidation of Prx III in mitochondria (Fig. 4D). Adenosine triphosphate Chronic ethanol feeding in Srx−/− mice increased the amount of Prx I-SO2 to 30 to 50% of total Prx I, which likely corresponds to virtually all ER-bound Prx I molecules. We did not detect Prx II-SO2 in the liver of ethanol-fed wildtype or Srx−/− mice, however, suggesting that Prx II was not engaged in ROS elimination rather than that the capacity of Srx in the cytosol was sufficient to counteract its hyperoxidation. Kupffer cells produce H2O2, which can diffuse across biological membranes and impose oxidative stress on hepatocytes. The apparent absence of Prx II-SO2 in the liver of Srx−/− mice, however, suggests that H2O2 molecules produced by Kupffer cells do not generate a high level of stress in hepatocytes. We did detect Prx III-SO2 in the liver of ethanol-fed Srx−/− mice, corroborating the notion that Prx III-SO2 was not detected in ethanol-fed Srx+/+ mice because mitochondrial Srx was sufficient to counteract Prx III hyperoxidation.

025, 1.055, and 1.21g/mL with NaBr before each following run, and fractions corresponding

respectively to IDL, LDL, and HDL were collected. Each fraction was then dialyzed at 4°C against 150 mM NaCl-0.24 mM ethylene diamine tetra-acetic acid (pH 7.4) buffer and filtered through 0.22-μm pore size filters (Millipore, Saint Quentin, France) before lipid extraction as described below. Plasma was adjusted to 1.055 g/mL with NaBr and centrifuged as described above. After collection, the upper low-density fraction (LDF) was dialyzed as described for lipoprotein fractions and stored at 4°C in the dark, in the presence of 2% protease inhibitor cocktail (P8340; Sigma-Aldrich). LVP purification selleck screening library from normal lipoproteins contained in LDF was performed via protein A immunoprecipitation of the immune complexes that are only found in the LDFs of infected patients as described.4 Briefly, protein A–coated magnetic beads (Miltenyi Biotec, Paris, France) were incubated with LDFs in phosphate-buffered saline (PBS) with gentle rocking for 30 minutes (20 μL of beads per 1

mL LDF). A total of 2 mL sample were then passed through one magnetic column (Miltenyi Biotec), washed with PBS, and collected in 500 μL PBS. For experiments with larger LDF volume, multiple columns were used. Immunocaptured particles (purified LVPs) were buy INK 128 subjected to lipid extraction as described below or stored at 4°C in the dark in the presence of 2% protease inhibitor cocktail for biochemical characterization. Protein concentration was determined using Coomassie Plus (Bradford)

Protein assay (ThermoScientific, Brebières, France). ApoB concentration in low-density fractions and sera was determined by immunochemical assay (SFRI Diagnostics, Saint-Jean d’Illiac, France). Total cholesterol (TChol), phospholipid, and triacylglycerol concentrations in sera were calculated with Cholesterol RTU, Phospholipid Enzymatic PAP150, and Triacylglycerol Enzymatic PAP150 kits (BioMérieux, Marcy l’étoile, France). ApoB concentration in purified LVPs was determined Fossariinae via enzyme-linked immunosorbent assay (ELISA) as described.20 Mock-prepared LVPs from healthy donors displayed a maximal background of <1% of lipids or apoB detected in LVPs prepared from patients. Lipid extraction of mock LVPs, as described below, has not allowed the detection of any fatty acid by gas chromatography (GC) in the final lipid extract. RNA was extracted from 150 μL serum, 10 μL lipoproteins, LDFs, or purified LVPs with a NucleoSpin RNA virus kit (Macherey-Nagel, Hoerdt, France) and stored at −80°C. HCV RNA quantification was performed using quantitative real-time polymerase chain reaction of the 5′ HCV noncoding region as described.22 HCV genotyping was performed using the INNO LiPA HCV assay (Innogenetics, Zwijnaarde, Belgium).

DAA, direct-acting antiviral; HCV, hepatitis C virus; PEG, pegylated interferon; RBV, ribavirin. The wait versus treat debate has begun once again with fervor. Proponents of deferring treatment for patients with early stage disease cite slow progression of HCV, toxicity of the current triple therapy, and the promise of more potent agents to come, as the backbone of justification to defer treatment. Those who advocate a “treat now” approach

cite an inability to accurately stage and predict fibrosis progression, as well as uncertainty over the true release date of the next generation of DAAs, as reasons to recommend current therapy. In this editorial, we highlight the ethical ramifications of treatment deferral. The underlying principles learn more of medical ethics tend to be stable over

time; however, the interpretation of these principles must be tailored to fit the ever-changing scientific landscape. Deferring HCV therapy pushes the doctor-patient relationship—specifically, the concept of informed consent—past its current boundaries and has created a need for a new concept: informed deferral. Informed Small molecule library consent consists of five key elements: (1) competence, (2) disclosure, (3) understanding, (4) voluntariness, and (5) consent.4 Patient participation in health care decision-making prior to the twentieth century was characterized by “benevolent deception and nondisclosure” while “concealing most things from the patient while you are attending to CYTH4 him.”5, 6 In 1914, the landmark case of Schloendorff

v Society of New York Hospital was pivotal in emphasizing the importance of patient autonomy.7 In this case, Mary Schloendorff agreed to an examination under anesthesia to determine whether a fibroid tumor was malignant, but specifically requested that no surgery take place. The surgeon removed the tumor nonetheless, and Mrs. Schloendorff sued the hospital for acting against her wishes. Ruling in favor of Mrs. Schloendorff, Judge Benjamin Cardozo stated: “Every human being of adult years and sound mind has the right to determine what shall be done with his own body,” hence creating the foundation of patient autonomy and shared medical decision-making. In discussing HCV therapy, the level of disclosure becomes germane. Standards of disclosure have evolved since the 1914 Schloendorff case from a “physician-centered” model to a “reasonable person” model, and finally to a “subjective standard” model. The “physician-centered” or professional practice model holds that a “professional community’s customary practices determine adequate disclosure.”4 Although this was an improvement from the nondisclosure practices of the past, this standard of disclosure rests on shaky moral ground.

1). Splenocytes and liver infiltrating MNCs were isolated as described[20] and resuspended in staining buffer consisting of 0.2% bovine serum albumin (BSA), 0.04% ethylenediaminetetraacetic acid (EDTA), and 0.05% sodium azide in phosphate-buffered saline (PBS). The cells were dispensed into

25-μL aliquots and incubated with antimouse Fc receptor blocking reagent (eBioscience, San Diego, CA) for 15 minutes at 4°C. Cells were washed and stained for 30 minutes at 4°C with cocktails containing combinations of fluorochrome conjugated monoclonal antibodies for the cell surface markers CD4, CD8a, CD44, CD62L, NK1.1, TCR Vα2, TCR Vβ5.1, 5.2 (Biolegend, San Diego, CA), and TCR-β (eBioscience). After staining, the cells were washed once with

PBS containing 0.2% BSA. For Cabozantinib order intracellular cytokine staining, splenic MNCs from dnTGFβRII, OT-I/dnTGFβRII/Rag1−/−, and OT-I/Rag1−/− mice were resuspended in RPMI 1640 medium with 10% heat-inactivated fetal bovine serum (Gibco-Invitrogen, Grand Island, NY), 100 μg/mL streptomycin, 100 U/mL penicillin, and 0.5 μg/mL each of anti-CD3 (Biolegend) and anti-CD28 (Biolegend) or 10 μg/mL the OVA amino acid 257-264 peptide (GenScript, Piscataway, NJ). The cells were incubated at 37°C in a humidified 5% CO2 incubator. Brefeldin A (1 μg/mL) (Sigma-Aldrich, St. Louis, MO) was added after 1 hour incubation. The cells were Deforolimus cost then incubated for 4 hours. The cells were stained for surface CD8a, NK1.1, and TCRβ, fixed, and permeabilized with BD Cytofix/Cytoperm Solution (BD Biosciences), then stained for intracellular IFNγ (BioLegend). Normal IgG isotype controls were used in parallel. A FACScan flow cytometer (BD Immunocytometry Systems, San Jose, CA) upgraded for the detection of five colors by Cytek Development (Fremont, CA) was used to acquire data, which were analyzed with Cellquest PRO software (BD Immunocytometry Systems). The liver from sacrificed mice were fixed in

4% paraformaldehyde, embedded in paraffin, cut into 4-μm sections, deparaffinized, stained with hematoxylin and eosin (H&E), and evaluated using light microscopy.[12] Portal inflammation were evaluated by a “blinded” pathologist Tideglusib using the following scoring system we have previously defined: 0, no inflammation; 1, minimal inflammation; 2, mild inflammation; 3, moderate inflammation; and 4, severe inflammation. Bile duct damage was graded as: 0, no significant changes; 1, mild change; 2, moderate to severe bile duct damage or bile duct loss. These data were expressed as the mean ± standard deviation (SD) and were evaluated with a two-tailed unpaired Mann-Whitney test, one-way analysis of variance (ANOVA) followed by a Bonferroni multiple comparison test, or a Kruskal-Wallis test followed by Dunn’s multiple comparisons test, as appropriate. We confirmed the composition of the splenic T-cell compartment in OT-I/dnTGFβRII/Rag1−/− and OT-II/dnTGFβRII/Rag1−/− mice.

The diagnosis of pseudocyst is often made by cross-sectional imaging such as CT. However, care must be taken to be sure that a fluid collection identified on CT does not represent evolving necrosis or WOPN, as CT imaging will often miss areas of necrotic tissue and debris within fluid collections.[25] A clinical history of severe acute pancreatitis suggests that resultant fluid collections have a high likelihood of representing WOPN. The management of pseudocysts and WOPN differs significantly and patients with WOPN treated as pseudocysts can have severe

complications.[25] Therefore, care should be taken to insure accurate diagnosis is made prior to any therapeutic intervention. The first description of endoscopic drainage of a pancreatic pseudocyst was in 1975. In this first account, Rogers used a transgastric needle to drain a pseudocyst.[26] Subsequently, our group published the first description of using endoscopic techniques selleckchem to fistulize pseudocysts into the stomach. Our initial case series demonstrated a permanent cure in three out of four patients.[27] While the procedure has been altered to some degree since then, it remains largely the same. The endoscopist must first achieve access to the cyst cavity. This is typically done with a needle-knife

sphincterotome EX-527 or a 19-gauge EUS needle. Patients should receive preprocedural antibiotics. Now most endoscopists use hydrostatic balloons of varying diameters to dilate the newly formed tract between the gastrointestinal lumen and the fluid collection. Once the cystogastrostomy or cystenterotomy has been dilated, the majority of endoscopists will place two or more double pigtail stents of varying sizes across the defect to maintain the patency of the fistula and oxyclozanide allow for complete resolution of the pseudocyst.[28-35] The use of double pigtail stents reduces the risk of migration as compared with straight stents.[36] Subsequent

to this drainage, resolution of the cyst cavity will generally occur over weeks to months. CT is typically used to monitor this process, and once the cavity has resolved, the stents can be removed. Alternatively, in the setting of DDS, the stents can be left in indefinitely.[37, 38] Some endoscopists will also perform an ERCP at the same time as pseudocyst drainage to characterize ductal anatomy and place a pancreatic duct stent if a persistent leak is identified.[1, 39] Endoscopic drainage of pseudocysts can be done with or without EUS. However, for patients who have concomitant gastric varices, it is generally preferable to utilize EUS so that intervening blood vessels can be identified and avoided. EUS is also very helpful in cases where a bulge within the gastrointestinal lumen cannot be identified on endoscopy.[33, 35, 40-42] New, therapeutic linear EUS scopes have a 3.7-mm diameter channel which allows for placement of up to 10-Fr stents and eliminates the need to exchange the EUS scope for a duodenoscope after the initial puncture.

These carotenoids learn more are of high commercial value as dyes in food and as nutraceuticals. The open reading frame (ORF) of CzlcyB encoded a polypeptide of 546 amino acids. A single copy of CzlcyB has been found in C. zofingiensis. The chararacteristic Rossmann or dinucleotide binding fold, present in most lycopene cyclases, has been also identified in the LCYb of C. zofingiensis (CzLCYb).

Heterologous genetic complementation in Escherichia coli showed the ability of the predicted protein to cycle both lycopene and δ-carotene. Phylogenetic analysis has shown that the deduced protein forms a cluster with the rest of the lycopene β-cyclases (LCYb) of the chlorophycean microalgae studied, being very closely related to LCYb of plants. Transcript levels of CzlcyB were increased

under nitrogen deprivation, but no increase was observed under high-light conditions. However, high irradiance triggered astaxanthin synthesis, while RG7204 ic50 nitrogen deprivation by itself could not induce it. The combination of high irradiance and nitrogen deprivation led to a significant enhancement of the astaxathin accumulation. “
“Accurate gene quantification depends on the use of an appropriate internal control gene, which should be verified before its use for normalizing data. Housekeeping genes, which are expressed at relatively constant levels, are generally regarded as candidate internal control genes. To determine the ideal internal control for gene expression profiles for Porphyra haitanensis T. J. Chang et B. F. Zheng (Bangiales, Rhodophyta) at different life-history stages, we used absolute quantification to assess the expression levels of six housekeeping genes (18S ribosomal RNA, 30S ribosomal protein, glyceraldehyde-3-phosphate dehydrogenase, elongation factor 3, alpha-tubulin, and beta-tubulin) at the sporophyte and gametophyte stages. Housekeeping genes were selected by comparing the differences of observed copy numbers in sporophytes and in gametophytes. TubB (beta-tubulin)

was found to be the optimal internal control gene, because it showed the smallest difference of gene expression. Compared with TubB, other housekeeping genes had greater D-malate dehydrogenase variation of expression to different degrees. “
“The short-term and long-term effects of elevated CO2 on photosynthesis and respiration were examined in cultures of the marine brown macroalga Hizikia fusiformis (Harv.) Okamura grown under ambient (375 μL · L−1) and elevated (700 μL · L−1) CO2 concentrations and at low and high N availability. Short-term exposure to CO2 enrichment stimulated photosynthesis, and this stimulation was maintained with prolonged growth at elevated CO2, regardless of the N levels in culture, indicating no down-regulation of photosynthesis with prolonged growth at elevated CO2. However, the photosynthetic rate of low-N-grown H.

Typically 1 or 2 weeks later, patients were then implanted with 90Y-resin microspheres. The 90Y-resin microspheres were provided in a 3-GBq vial calibrated for 23:00 Greenwich Mean Time on the day of treatment. Patients with bilobar involvement were treated according to local protocols either in a single session or using sequential lobar therapies, typically 4-6 weeks apart. Patients were typically discharged the day after radioembolization, depending upon local regulations. Hematological,

liver function, and blood biochemistry tests and physical examination were performed pretreatment. Data were collated from the medical records for baseline and 3, 6, 9, and 12 months following treatment for serum levels of liver aminotransferase, albumin, total bilirubin, prothrombin activity, creatinine, and alpha-fetoprotein levels. The nature selleck products and severity of all adverse events were accessed from the medical records from the day

Alectinib clinical trial of radioembolization to day 180 posttreatment, although the analysis of clinical and laboratory adverse events was performed on baseline to day 90 data because this was the most representative for treatment related events. All adverse events were graded using National Cancer Institute Common Toxicity Criteria Adverse Events Version 3.0. Survival was calculated from the day of treatment to the day of death or last follow-up. Those patients in whom status could not be established were censored at the time of last follow-up. Patients undergoing resection, transplantation, or percutaneous ablation following radioembolization were censored at the time of surgery or ablation. Patient survival was summarized using the Kaplan-Meier product-limit method to compute nonparametric estimates of survivor function. Univariate Cox proportional hazards models

were applied to identify single-vector prognostic factors associated with survival, and a log-rank test at an alpha error level of 0.05 was used to compare survival curves among strata. A univariate Cox proportional hazards model was used to compare prognostic C59 variables, summarized by the hazards ratio and its 95% confidence interval (CI). The multivariate proportional hazards model was applied to the statistically significant univariate variables by Kaplan-Meier (log-rank test) or Cox proportional hazards model at alpha 0.05, and the analysis model was constructed based on the maximum number of statistically significant variables (best subsets approach),27 using the Akaike information criteria for model selection. A multivariate model was constructed to test the significance of prognostic indicators of survival in addition to BCLC. Associations between covariates (yes/no) and Common Terminology Criteria for Adverse Events (CTCAE) grade were tested by Fisher’s exact test and Cochran-Mantel-Haenszel row mean score. Transitions in CTCAE grades were tested by the exact McNemar’s test.

12 In that study, green areas in the gastric body exhibited more inflammation (P < 0.001), atrophy (P < 0.01) and intestinal metaplasia (P < 0.001), whereas purple areas rarely contained selleck kinase inhibitor atrophy or intestinal metaplasia. The

results clearly showed that AFI could be used to diagnose the extent of chronic atrophic fundic gastritis as a green area in the gastric body, with improved reproducibility compared with white-light endoscopy.10 Based on the previous study, the authors observed the pattern of chronic atrophic fundic gastritis in the patients undergoing ESD for EGC. They categorized it into closed and open type for assessment of chronic atrophic fundic gastritis by AFI in the article in this issue of JGH. The results showed that open-type atrophic gastritis was significantly associated with development of metachronous EGC (hazard ratio: 4.88, 95% confidence interval:1.32–18.2, P = 0.018) after adjustment for age, sex, histological intestinal metaplasia, serum pepsinogen level, and H. pylori status.6 The role of AFI as an easy tool for measuring chronic fundic atrophic Epacadostat concentration gastritis should be verified by other researchers. Nevertheless, this article provides useful information for endoscopists to apply AFI

to another clinical purpose. More information about AFI is needed to establish its clinical usefulness as an approach to study and diagnose gastrointestinal diseases. In the future, expanded studies comprising large numbers of subjects may be able to clearly demonstrate its value. “
“Screening for hepatocellular carcinoma (HCC) is clinically important as

its early detection has remarkable survival benefits. We investigated the possible role of FIB-4, a recently developed noninvasive marker Verteporfin price for liver fibrosis based on routine laboratory tests, as a clinical indicator for predicting future HCC among hepatitis B surface antigen (HBsAg) carriers. Our retrospective cohort study involved 986 Korean HBsAg carriers aged 40 or older who visited Seoul National University Hospital for health check-up. National medical service claims data was used to determine HCC incidence. Median follow-up time was 5.4 years (interquartile range 4.4 years). Adjusted for age, sex, body mass index, smoking, alcohol, and anti-viral medication for hepatitis B, compared to subjects with FIB-4 <1.25, subjects with 1.7≤ FIB-4 <2.4 showed aHR 4.57 (95% CI 1.50-13.92) and subjects with FIB-4 ≥2.4 showed aHR 21.34 (95% CI 7.73-58.92) for HCC incidence. FIB-4 was shown to have incremental predictive value to ultrasonographic liver cirrhosis for HCC incidence (C-index 0.701 vs. 0.831; P=0.001). FIB-4 was also better predictive of HCC incidence compared to that of ultrasonographic liver cirrhosis (C-index 0.775 vs. 0.701; P=0.040).
