Abstract
BACKGROUND & AIMS Identifying individuals at higher risk of developing hepatocellular carcinoma (HCC) is pivotal to improve the performance of surveillance strategies. Herein, we aimed to evaluate the ability of single nucleotide polymorphisms (SNPs) to refine HCC risk stratification. METHODS Six SNPs in PNPLA3, TM6SF2, HSD17B13, APOE, and MBOAT7 affecting lipid turnover and one variant involved in the Wnt-β-catenin pathway (WNT3A-WNT9A rs708113) were assessed in patients with alcohol-related and/or HCV-cured cirrhosis included in HCC surveillance programmes (prospective CirVir and CIRRAL cohorts). Their prognostic value for HCC occurrence was assessed using Fine-Gray models combined into a 7-SNP genetic risk score (GRS). The predictive ability of two clinical scores (a routine non-genetic model determined by multivariate analysis and the external aMAP score) with/without the GRS was evaluated by C-indices. The standardised net benefit was derived from decision curves. RESULTS Among 1,145 patients, 86 (7.5%) developed HCC after 43.7 months. PNPLA3 and WNT3A-WNT9A variants were independently associated with HCC occurrence. The GRS stratified the population into three groups with progressively increased 5-year HCC incidence (Group 1 [n = 627, 5.4%], Group 2 [n = 276, 10.7%], and Group 3 [n = 242, 15.3%]; p <0.001). The multivariate model identified age, male sex, diabetes, platelet count, gamma-glutamyltransferase levels, albuminemia and the GRS as independent risk factors. The clinical model performance for 5-year HCC prediction was similar to that of the aMAP score (C-Index 0.769). The addition of the GRS to both scores modestly improved their performance (C-Indices of 0.786 and 0.783, respectively). This finding was confirmed by decision curve analyses showing only fair clinical net benefit. CONCLUSIONS Patients with cirrhosis can be stratified into HCC risk classes by variants affecting lipid turnover and the Wnt-β-catenin pathway. The incorporation of this genetic information modestly improves the performance of clinical scores. IMPACT AND IMPLICATIONS The identification of patients at higher risk of developing liver cancer is pivotal to improve the performance of surveillance. Risk assessment can be achieved by combining several clinical and biological parameters used in routine practice. The addition of patients' genetic characteristics can modestly improve this prediction and will ultimately pave the way for precision medicine in patients eligible for HCC surveillance, allowing physicians to trigger personalised screening strategies.

Abstract
Purpose Sulfatase 2 (SULF2) is an enzyme related to heparan sulfate modifications. Its expression, as for some heparan sulfate proteoglycans expression, has been linked to hepatocellular carcinoma (HCC) at mRNA level and immunohistochemistry staining on biopsy samples. This study aims to evaluate the prognostic value of serum levels of SULF2 in patients with alcoholic cirrhosis with or without HCC. Patients and Methods Two hundred and eighty-seven patients with alcoholic cirrhosis were enrolled in this study: 164 without HCC, 57 with early HCC, and 66 with advanced HCC at inclusion. We analyzed the association between SULF2 serum levels and prognosis using Kaplan-Meier method and univariate and multivariate analysis using a Cox model. Results Child-Pugh C Patients have higher serum levels of SULF2 than Child-Pugh A patients. Serum levels of SULF2 were also higher in patients with advanced HCC compared with the other groups. In patients with advanced HCC, high serum levels of SULF2 were associated with less favorable overall survival. Combination of SULF2 with Glypican 3 (GPC3) and Syndecan 1 (SDC1) serum levels enhanced the ability to discriminate worst prognostic in advanced HCC. Conclusion SULF2 along with GPC3 and SDC1 serum levels have been shown to be associated with a prognostic value in advanced HCC.

Abstract
Atherosclerosis, in the ultimate stage of cardiovascular diseases, causes an obstruction of vessels leading to ischemia and finally to necrosis. To restore vascularization and tissue regeneration, stimulation of angiogenesis is necessary. Chemokines and microRNAs (miR) were studied as pro-angiogenic agents. We analysed the miR-126/CXCL12 axis and compared impacts of both miR-126-3p and miR-126-5p strands effects in CXCL12-induced angiogenesis. Indeed, the two strands of miR-126 were previously shown to be active but were never compared together in the same experimental conditions regarding their differential functions in angiogenesis. In this study, we analysed the 2D-angiogenesis and the migration assays in HUVEC in vitro and in rat's aortic rings ex vivo, both transfected with premiR-126-3p/-5p or antimiR-126-3p/-5p strands and stimulated with CXCL12. First, we showed that CXCL12 had pro-angiogenic effects in vitro and ex vivo associated with overexpression of miR-126-3p in HUVEC and rat's aortas. Second, we showed that 2D-angiogenesis and migration induced by CXCL12 was abolished in vitro and ex vivo after miR-126-3p inhibition. Finally, we observed that SPRED-1 (one of miR-126-3p targets) was inhibited after CXCL12 treatment in HUVEC leading to improvement of CXCL12 pro-angiogenic potential in vitro. Our results proved for the first time: 1-the role of CXCL12 in modulation of miR-126 expression; 2-the involvement of miR-126 in CXCL12 pro-angiogenic effects; 3-the involvement of SPRED-1 in angiogenesis induced by miR-126/CXCL12 axis.

Abstract
BACKGROUND AND AIM The prognostic value of transient elastography (TE) in cirrhotic patients with hepatocellular carcinoma (HCC) treated by percutaneous radiofrequency ablation (RFA) is currently unknown. METHOD(S) We included patients with histologically proven cirrhosis and with a first diagnosis of HCC inside Milan criteria treated by percutaneous RFA, and with TE available the year before treatment with 10 shots and interquartile range/median < 30%. Association between variables and clinical events was assessed by the Kaplan-Meier method with the log-rank test and using Cox univariate and multivariate analyses. RESULTS One hundred fifty-nine patients were included, with a median age of 65 years; 77.4% were men. Causes of cirrhosis were alcohol consumption (48.1%), hepatitis C (43.7%), hepatitis B (12.7%), and non-alcoholic steatohepatitis (32.3%). Median value of TE was 26 kPa (4-75 kPa). Overall survival at 1, 2, and 5 years was, respectively, 93%, 81%, and 44%; overall recurrence was 28%, 49%, and 80%. The TE value was not associated with tumor recurrence (0.13). In contrast, in univariate analysis, TE value, age, Child-Pugh B, and alkaline phosphatase were predictive factors in overall survival. In multivariate analysis, TE value (hazards ratio [HR] = 1.02, 95% confidence interval (IC): 1.01-1.04, 0.001), age (HR = 1.05, 95% IC: 1.03-1.08, P = 0.00006), and Child-Pugh B score (HR = 2.78, 95% IC: 1.27-6.08, P = 0.01) were independently associated with higher risk of death. A TE value ≥ 40 kPa was associated with shorter median overall survival (34 months) compared to a TE value < 40 kPa (59 months, P = 0.0008). CONCLUSION(S) Transient elastography (TE) predicts overall survival but not tumor recurrence in cirrhotic patients with HCC treated by RFA.

Abstract
Recently, a loss of function variant (rs72613567) in 17-beta-hydroxysteroid dehydrogenase 13 (HSD17B13) has been identified as protective of nonalcoholic (NAFLD) and alcoholic liver disease (ALD). However, the role of this single-nucleotide polymorphism (SNP) in the development of hepatocellular carcinoma (HCC) is currently unknown. A total of 3,315 European patients with HCC (n = 1,109) or without HCC, but with chronic liver disease (CLD; n = 2,206), from four centers were analyzed either by whole-exome sequencing (WES; exploratory cohort, 285 HCC) or genotyped for HSD17B13 rs72613567 (validation cohort, 824 HCC and all CLD). We included a control group of 33,337 healthy European individuals from the Exome Aggregation Consortium. We compared distribution of genotype using the chi-square test and logistic regression. In the exploratory cohort analyzed by WES, frequency of the TA allele of HSD17B13 rs72613567 was significantly decreased in HCC patients compared to healthy controls (P = 1.52 × 10-06 ). In the validation cohort, frequency of TA allele carriers was also decreased in patients with CLD and without HCC (39%) compared to healthy individuals (47%; P < 0.0001). The protective effect of the TA allele of HSD17B13 rs72613567 was identified in patients with ALD (odds ratio [OR] = 0.73; 95% confidence interval [CI], 0.65-0.82; P < 0.0001), NAFLD (OR = 0.64; 95% CI, 0.49-0.83; P = 0.0007), and hepatitis C (OR = 0.71; 95% CI, 0.60-0.85; P = 0.0002). In patients with ALD, the proportion of TA allele carriers with HCC was significantly lower (32%) than in CLD patients without HCC (40%), even after adjustment for age, sex, and fibrosis (OR = 0.64; 95% CI, 0.46-0.87; P = 0.005). Conclusion: The HSD17B13 rs72613567 loss of function variant is protective of HCC development in patients with ALD.

Abstract
BACKGROUND We aimed to identify the main determinants of long-term overall survival (OS), including virologic control, and recurrence after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) on cirrhosis. METHODS Cirrhotic patients treated by RFA for HCC within Milan criteria were included. Associations between patient features and events were estimated by the Kaplan-Meier method with the log rank test and using uni/multivariate Cox models. RESULTS 389 cirrhotic patients (Child-Pugh A 86.6%, 473 tumors) were included. OS was 79.8%, 42.4% and 16%, and overall tumor recurrence 45%, 78% and 88% at 2, 5 and 10 years, respectively. In multivariate analysis, age, Child-Pugh, GGT, HCC near major vessels, esophageal varices, alkaline phosphatase and HBV predicted OS. Gender, ALT, AFP and alcohol intake were associated with tumor recurrence. Multinodular HCC (19.5%) was associated with risk of tumor recurrence outside Milan criteria. HBV patients had longer OS than other patients (P = 0.0059); negative HBV PCR at RFA was associated with decreased tumor recurrence (P = 0.0157). Using time-dependent analysis in HCV patients, a sustained virologic response was associated with increased OS (124.5 months) compared to other patients (49.2 months, P < 0.001). CONCLUSION Virologic response and severity of underlying liver disease were the main determinants of long-term OS after RFA for HCC developing on cirrhosis.

Abstract
Background : The combination of dexamethasone (DEX), ondansetron (OND) and droperidol (DRO) is efficacious in preventing postoperative nausea and vomiting in adults, but has not been well assessed in children. Methods : Children undergoing elective surgery under general anaesthesia and considered at high risk for postoperative vomiting (POV) were randomly assigned to receive a combination of DEX, OND and placebo (Group A) or a combination of DEX, OND and DRO (Group B). The primary outcome was the incidence of POV during the first 24 hours after surgery. We hypothesized that the addition of DRO to the standard antiemetic prophylaxis would provide a further 15% reduction in the residual risk for POV. The secondary outcome considered was any adverse event occurring during the study. Results : One hundred and fifty-three children, aged three to 16 years, were randomized to Group A and 162 to Group B. The overall incidence of POV did not differ significantly between the two groups, with 16 patients in Group A (10.5%) and 18 in Group B (11.1%) presenting with one or more episodes of POV, P =0.86. Fewer patients presented with adverse events in Group A (2%) compared with Group B (8%), P =0.01. Drowsiness and headache were the principal adverse events reported. Conclusions : The addition of DRO to a combination of OND and DEX did not decrease POV frequency below that obtained with the two-drug combination in children at high risk of POV, but increased the risk of drowsiness. The combination of DEX and OND should be recommended in children with a high risk of POV. Clinical trial registration. NCT01739985.

Abstract
Few single nucleotide polymorphisms (SNPs) have been reproducibly associated with hepatocellular carcinoma (HCC). Our aim was to test the association between nine SNPs and HCC occurrence. SNPs in genes linked to HCC (DEPDC5, GRIK1, KIF1B, STAT4, MICA, DLC1, DDX18) or to liver damage (PNPLA3-rs738409, TM6SF2-rs58542926) in GWAS were genotyped in discovery cohorts including 1,020 HCC, 2,021 controls with chronic liver disease and 2,484 healthy individuals and replication was performed in prospective cohorts of cirrhotic patients with alcoholic liver disease (ALD, n = 249) and hepatitis C (n = 268). In the discovery cohort, PNPLA3 and TM6SF2 SNPs were associated with HCC (OR = 1.67 [CI95%:1.16-2.40], p = 0.005; OR = 1.45 [CI95%:1.08-1.94], p = 0.01) after adjustment for fibrosis, age, gender and etiology. In contrast, STAT4-rs7574865 was associated with HCC only in HBV infected patients (p = 0.03) and the other tested SNP were not linked with HCC risk. PNPLA3 and TM6SF2 variants were independently associated with HCC in patients with ALD (OR = 3.91 [CI95%:2.52-6.06], p = 1.14E-09; OR = 1.79 [CI95%:1.25-2.56], p = 0.001) but not with other etiologies. PNPLA3 SNP was also significantly associated with HCC developed on a nonfibrotic liver (OR = 2.19 [CI95%:1.22-3.92], p = 0.007). The association of PNPLA3 and TM6SF2 with HCC risk was confirmed in the prospective cohort with ALD. A genetic score including PNPLA3 and TM6SF2 minor alleles showed a progressive significant increased risk of HCC in ALD patients. In conclusion, PNPLA3-rs738409 and TM6SF2-rs58542926 are inherited risk variants of HCC development in patients with ALD in a dose dependent manner. The link between PNPLA3 and HCC on nonfibrotic liver suggests a direct role in liver carcinogenesis.

Abstract
Herein we investigate the structure/function relationships of fucoidans from Ascophyllum nodosum to analyze their pro-angiogenic effect and cellular uptake in native and glycosaminoglycan-free (GAG-free) human endothelial cells (HUVECs). Fucoidans are marine sulfated polysaccharides, which act as glycosaminoglycans mimetics. We hypothesized that the size and sulfation rate of fucoidans influence their ability to induce pro-angiogenic processes independently of GAGs. We collected two fractions of fucoidans, Low and Medium Molecular Weight Fucoidan (LMWF and MMWF, respectively) by size exclusion chromatography and characterized their composition (sulfate, fucose and uronic acid) by colorimetric measurement and Raman and FT-IR spectroscopy. The high affinities of fractionated fucoidans to heparin binding proteins were confirmed by Surface Plasmon Resonance. We evidenced that LMWF has a higher pro-angiogenic (2D-angiogenesis on Matrigel) and pro-migratory (Boyden chamber) potential on HUVECs, compared to MMWF. Interestingly, in a GAG-free HUVECs model, LMWF kept a pro-angiogenic potential. Finally, to evaluate the association of LMWF-induced biological effects and its cellular uptake, we analyzed by confocal microscopy the GAGs involvement in the internalization of a fluorescent LMWF. The fluorescent LMWF was mainly internalized through HUVEC clathrin-dependent endocytosis in which GAGs were partially involved. In conclusion, a better characterization of the relationships between the fucoidan structure and its pro-angiogenic potential in GAG-free endothelial cells was required to identify an adapted fucoidan to enhance vascular repair in ischemia.

Abstract
BACKGROUND Prognostic biomarkers are needed in a heterogeneous population of patients with intermediate hepatocellular carcinoma (HCC) treated by transarterial (chemo)embolization. We aimed to validate the prognostic value of serum CRP levels and the STATE score, combining CRP, albumin and tumor burden. METHODS All cirrhotic patients with HCC treated by a first transarterial (chemo)embolization (2007-2013) in our institution were included. Overall survival was assessed using the Kaplan-Meier method, log rank, univariate and multivariate Cox analyses. RESULTS Among 157 patients included, 87% were men, 86% had Child Pugh A. Etiologies of liver disease included alcohol (57%), hepatitis C (32%), hepatitis B (11%) and/or metabolic syndrome (32%); 89% of patients were classified BCLC B. 33% of the patients had a CRP >1mg/dl and 33% a STATE score conferring poor prognosis (<18). Patients with CRP <1mg/dl had better overall survival than patients with CRP >1mg/dl (20 vs. 8 months, P=0.00186). Median overall survival was 6.73 months for patients with a STATE score <18 vs. 22.23 months for patients with STATE-score ≥18 (P=0.0002). In multivariate analysis, a STATE score <18 was independently associated with increased mortality (HR: 2.06 (CI95%: 1.28-3.34), P=0.0031). CONCLUSION In cirrhotic patients with HCC who underwent transarterial treatment, serum CRP level and STATE score at baseline can predict overall survival.

Children represent a population at risk, because of their short size, their naivety and their attraction to animals. The face and hands are the most specific locations in young children. Wounds are often multiple. In more than half the cases, the child knows the animal, which are dogs and cats by frequency argument. The bite episode occurs mostly when the child is alone with the pet without direct supervision, while playing or stroking the animal. As in all bites, pediatric lesions are infectious, functional and aesthetic emergencies, but the goal of this work was primarily to make a point on principles of surgical management of animal bites in children, highlighting pediatric specificities. Animal bites require psychological, anesthetic and surgical treatment, adapted to the child, in a specialized structure. Hospitalization and general anesthesia are more frequent in children. Any suspicion of mistreatment (and/or abuse) should lead to the child's hospitalization, even if wounds do not justify monitoring in a surgical environment. Emergency surgery is essential to limit functional and aesthetic consequences. The healing capacities of the child and the frequent lack of co-morbidity allow a conservative surgical treatment with suture, repositioning skin flaps and controlled healing in the first place. Immobilization, drainage, and antibiotics will complete the surgery. The healing process, however, leads to a specific management during scar remodeling phase and growth. Psychological care of the child and parents should not be forgotten, and has to start at the same time as surgical treatment at in acute phase.

Abstract
The molecular mechanisms of hepatocellular carcinoma (HCC) carcinogenesis are still not fully understood. DNA repair defects may influence HCC risk. The aim of the study was to look for potential genetic variants of DNA repair genes associated with HCC risk among patients with alcohol- or viral-induced liver disease. We performed four case-control studies on 2,006 European- (Derivation#1 and #2 studies) and African-ancestry (Validation#1 and #2 studies) patients originating from several cohorts in order to assess the association between genetic variants on DNA repair genes and HCC risk using a custom array encompassing 94 genes. In the Derivation#1 study, the BRIP1 locus reached array-wide significance (Chi-squared SV-Perm, P=5.00×10-4) among the 253 haplotype blocks tested for their association with HCC risk, in patients with viral cirrhosis but not among those with alcoholic cirrhosis. The BRIP1 haplotype block included three exonic variants (rs4986763, rs4986764, rs4986765). The BRIP1 'AAA' haplotype was significantly associated with an increased HCC risk [odds ratio (OR), 2.01 (1.19-3.39); false discovery rate (FDR)-P=1.31×10-2]. In the Derivation#2 study, results were confirmed for the BRIP1 'GGG' haplotype [OR, 0.53 (0.36-0.79); FDR-P=3.90×10-3]. In both Validation#1 and #2 studies, BRIP1 'AAA' haplotype was significantly associated with an increased risk of HCC [OR, 1.71 (1.09-2.68); FDR-P=7.30×10-2; and OR, 6.45 (4.17-9.99); FDR-P=2.33×10-19, respectively]. Association between the BRIP1 locus and HCC risk suggests that impaired DNA mismatch repair might play a role in liver carcinogenesis, among patients with HCV- or HBV-related liver disease.

Abstract
It is well known that several metals, such as lead, mercury, cadmium, and vanadium, can mimic the effects of estrogens (metallo-estrogens). Nevertheless, there are only a few studies that have assessed the effects of toxic metals on the female genital tract and, in particular, endometrial tissue. In this context, we measured the concentrations of several trace elements in human endometrial tissue samples from individuals with hyperplasia or adenocarcinoma and in normal tissues. Hyperplasic endometrial tissue has a 4-fold higher concentration of mercury than normal tissue. Mercury can affect both the AhR and ROS signaling pathways. Thus, we investigated the possible toxic effects of mercury by in vitro studies. We found that mercury increases oxidative stress (increased HO1 and NQO1 mRNA levels) and alters the cytoskeleton in the human endometrial Ishikawa cell line and to a lesser extent, in the "less-differentiated" human endometrial Hec-1b cells. The results might help to explain a potential link between this metal and the occurrence of endometrial hyperplasia.

Abstract
The perpetuation of angiogenesis is involved in certain chronic inflammatory diseases. The accelerated neovascularisation may result from an inflammatory status with a response of both endothelial cells and monocytes to inflammatory mediators such as chemokines. We have previously described in vitro and in vivo the pro-angiogenic effects of the chemokine Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES)/CCL5. The effects of RANTES/CCL5 may be related to its binding to G protein-coupled receptors and to proteoglycans such as syndecan-1 and -4. The aim of this study was to evaluate the functionality of syndecan-4 as a co-receptor of RANTES/CCL5 by the use of mutated syndecan-4 constructs. Our data demonstrate that site-directed mutations in syndecan-4 modify RANTES/CCL5 biological activities in endothelial cells. The SDC4S179A mutant, associated with an induced protein kinase C (PKC)α activation, leads to higher RANTES/CCL5 pro-angiogenic effects, whereas the SDC4L188QQ and the SDC4A198del mutants, leading to lower phosphatidylinositol 4,5-bisphosphate (PIP2) binding or to lower PDZ protein binding respectively, are associated with reduced RANTES/CCL5 cellular effects. Moreover, our data highlight that the intracellular domain of SDC-4 is involved in RANTES/CCL5-induced activation of the PKCα signaling pathway and biological effect. As RANTES/CCL5 is involved in various physiopathological processes, the development of a new therapeutic strategy may be reliant on the mechanism by which RANTES/CCL5 exerts its biological activities, for example by targeting the binding of the chemokine to its proteoglycan receptor.

Abstract
Aromatic amines (AAs) are an important class of chemicals which account for 12 % of known carcinogens. The biological effects of AAs depend mainly on their biotransformation into reactive metabolites or into N-acetylated metabolites which are generally considered as less toxic. Although the activation of the aryl hydrocarbon receptor (AhR) pathway by certain carcinogenic AAs has been reported, the effects of their N-acetylated metabolites on the AhR have not been addressed. Here, we investigated whether carcinogenic AAs and their N-acetylated metabolites may activate/modulate the AhR pathway in the absence and/or the presence of a bona fide AhR ligand (benzo[a]pyrene/B(a)P]. In agreement with previous studies, we found that certain AAs activated the AhR in human liver and lung cells as assessed by an increase in cytochrome P450 1A1 (CYP1A1) expression and activity. Altogether, we report for the first time that these properties can be modulated by the N-acetylation status of the AA. Whereas 2-naphthylamine significantly activated the AhR and induced CYP1A1 expression, its N-acetylated metabolite was less efficient. In contrast, the N-acetylated metabolite of 2-aminofluorene was able to significantly activate AhR, whereas the parent AA, 2-aminofluorene, did not. In the presence of B(a)P, activation of AhR or antagonist effects were observed depending on the AA or its N-acetylated metabolite. Activation and/or modulation of the AhR pathway by AAs and their N-acetylated metabolites may represent a novel mechanism contributing to the toxicological effects of AAs. More broadly, our data suggest biological interactions between AAs and other classes of xenobiotics through the AhR pathway.

Abstract
BACKGROUND & AIMS Genetic polymorphisms modulate the expression of proinflammatory cytokines. We prospectively assessed the influence of 6 single nucleotide polymorphisms (SNPs) in TNFα, IL6, and IL1β genes on the risk of hepatocellular carcinoma (HCC) in patients with cirrhosis. METHODS TNFα (G-238A, C-863A, G-308A), IL6 (C-174G), and IL1β (C-31T, C-511T) SNPs were assessed in 232 alcoholics and 253 HCV-infected patients with biopsy-proven cirrhosis, prospectively followed-up and screened for HCC. Their influence on HCC development was assessed using the Kaplan-Meier method. RESULTS These variants did not influence the risk of HCC in alcoholic patients. Conversely, two variants influenced the risk of HCC occurrence in patients with HCV-related cirrhosis, namely the TNFα-308 (A) allele (HR = 2.4 [1.6-3.7], Log-rank <0.0001) and the IL1β-31 (T) allele (HR = 1.5 [1.1-2.1], Log-rank = 0.004). When stratifying HCV-infected patients into four genotypic associations expected to progressively increase TNFα and IL1β production, we observed increasing risk of HCC occurrence (Log-rank <0.0001) from group 1 to 4. The TNFα-308 (A) allele was the only genetic trait independently associated with risk of HCC in these patients, along with older age, male gender, BMI, and platelet count. These variables led to construction of a predictive score able to separate patients with HCV-related cirrhosis into three subgroups with progressively increasing 5-year cumulative incidences of 4.7%, 14.1%, and 36.3%, respectively (Log-rank <0.0001). CONCLUSIONS Genetic heterogeneity in the TNFα and IL1β gene promoters influences the risk of HCC in patients with HCV-induced cirrhosis. These genetic data, when incorporated into clinical scores, are able to refine selection of risk classes of HCC.

Abstract
UNLABELLED The incidence of hepatocellular carcinoma (HCC) is increasing in Western countries. Although several clinical factors have been identified, many individuals never develop HCC, suggesting a genetic susceptibility. However, to date, only a few single-nucleotide polymorphisms have been reproducibly shown to be linked to HCC onset. A variant (rs738409 C>G, encoding for p.I148M) in the PNPLA3 gene is associated with liver damage in chronic liver diseases. Interestingly, several studies have reported that the minor rs738409[G] allele is more represented in HCC cases in chronic hepatitis C (CHC) and alcoholic liver disease (ALD). However, a significant association with HCC related to CHC has not been consistently observed, and the strength of the association between rs738409 and HCC remains unclear. We performed a meta-analysis of individual participant data including 2,503 European patients with cirrhosis to assess the association between rs738409 and HCC, particularly in ALD and CHC. We found that rs738409 was strongly associated with overall HCC (odds ratio [OR] per G allele, additive model=1.77; 95% confidence interval [CI]: 1.42-2.19; P=2.78 × 10(-7) ). This association was more pronounced in ALD (OR=2.20; 95% CI: 1.80-2.67; P=4.71 × 10(-15) ) than in CHC patients (OR=1.55; 95% CI: 1.03-2.34; P=3.52 × 10(-2) ). After adjustment for age, sex, and body mass index, the variant remained strongly associated with HCC. CONCLUSION Overall, these results suggest that rs738409 exerts a marked influence on hepatocarcinogenesis in patients with cirrhosis of European descent and provide a strong argument for performing further mechanistic studies to better understand the role of PNPLA3 in HCC development.

Abstract
BACKGROUND Proteoglycans are involved in neoangiogenesis and transduction of oncogenic signals, two hallmarks of carcinogenesis. METHODS This study sought to assess the prognostic value of serum levels of three proteoglycans (endocan, syndecan-1, and glypican-3) and VEGF in 295 patients with alcoholic cirrhosis: 170 without hepatocellular carcinoma, 58 with early hepatocellular carcinoma, and 67 with advanced hepatocellular carcinoma at inclusion. We analyzed the association between proteoglycan levels and prognosis using Kaplan-Meier and Cox methods. RESULTS Serum levels of the three proteoglycans and VEGF were increased in patients with advanced hepatocellular carcinoma compared with those without hepatocellular carcinoma or with early hepatocellular carcinoma. In multivariate analysis, high levels of serum endocan (>5 ng/mL) were independently associated with death [HR, 2.84; 95% confidence interval (CI,) 1.18-6.84; P = 0.02], but not with hepatocellular carcinoma occurrence, in patients without hepatocellular carcinoma at baseline. High serum endocan (>5 ng/mL) and syndecan-1 (>50 ng/mL) levels were significantly associated with greater risk of tumor recurrence (P = 0.025) in patients with early hepatocellular carcinoma treated by radiofrequency ablation. In patients with advanced hepatocellular carcinoma, high serum levels of endocan (P = 0.004) and syndecan-1 (P = 0.006) were significantly associated with less favorable overall survival. However, only a high level of serum syndecan-1 (>50 ng/mL) was independently associated with greater risk of death (HR, 6.21 95% CI, 1.90-20.30; P = 0.0025). CONCLUSION Serum endocan and syndecan-1 are easily assessable prognostic serum biomarkers of overall survival in alcoholic cirrhosis with and without hepatocellular carcinoma. IMPACT These new biomarkers will be useful to manage patients with hepatocellular carcinoma developed on alcoholic cirrhosis.

Abstract
The aryl hydrocarbon receptor (AhR) is a transcription factor which is activated by diverse compounds and regulates the expression of xenobiotic metabolism genes. Recent studies have unraveled unsuspected physiological roles and novel alternative ligand-specific pathways for this receptor. In this review, we discuss these novel aspects and focus on the different responses elicited by the diverse endogenous and/or exogenous AhR ligands. In addition to challenging the relevance of the 'agonist/antagonist' classification of ligands, we introduce the concept of AhR plasticity as a primordial factor in the generation of these pathways. Finally, we suggest several promising perspectives for the pharmacological modulation of these responses.

Abstract
Paraoxonase 1 (PON1) is a high-density lipoprotein-associated enzyme, synthesized in the liver and secreted into the blood. PON1 displays antioxidant properties and is involved in organophosphorous compounds and oxidized lipids degradation. Because of these beneficial effects, pharmacological regulation of PON1 appears to be highly relevant in toxicology and cardiology. Recent studies undertaken on the regulation of the PON1 promoter in our laboratory have identified resveratrol, through its activation of the Aryl hydrocarbon Receptor (AhR), as a putative inducer of PON1. We have tested a new modulator of AhR, (Z)-2,3-bis (4-nitrophenyl)-acrylonitrile, and established that it is a more potent inducer of PON1 at the mRNA, protein and enzymatic activity as compared to resveratrol. It also acts by activating the AhR. However, in contrast with traditional AhR agonists, it does not induce cyp1A1 transcription. (Z)-2,3-bis (4-nitrophenyl)-acrylonitrile is therefore a specific AhR modulator targeting PON1.

Abstract
OBJECTIVE Assessment of executive functions in an everyday life activity, evaluating brain injury subjects with script generation and execution tasks. MATERIALS AND METHODS We compared a script generation task to a script execution task, whereby subjects had to make a cooked dish. Two grids were used for the quotation, qualitative and quantitative, as well as the calculation of an anosognosis score. We checked whether the execution task was more sensitive to a dysexecutive disorder than the script generation task and compared the scores obtained in this evaluation with those from classical frontal tests. Twelve subjects with brain injury 6 years+/-4.79 ago and 12 healthy control subjects were tested. The subjects carried out a script generation task whereby they had to explain the necessary stages to make a chocolate cake. They also had to do a script execution task corresponding to the cake making. RESULTS The 2 quotation grids were operational and complementary. The quantitative grid is more sensitive to a dysexecutive disorder. The brain injury subjects made more errors in the execution task. CONCLUSION It is important to evaluate the executive functions of subjects with brain injury in everyday life tasks, not just in psychometric or script-generation tests. Indeed the ecological realization of a very simple task can reveal executive function difficulties such as the planning or the sequencing of actions, which are under-evaluated in laboratory tests.

Abstract
BACKGROUND A new intravenous (i.v.) formulation of paracetamol and propacetamol (prodrug of paracetamol) were compared to determine tolerance and relative analgesic efficacy during the first 6 h after inguinal hernia repair performed under general anesthesia combined with ilioinguinal block in children. METHODS A total of 183 ASA I or II in-patients, aged 1-12 years, admitted for unilateral inguinal hernia repair were randomized to receive in a double-blind design either i.v. paracetamol 15 mg.kg(-1) (n = 95) or propacetamol 30 mg.kg(-1) (n = 88) for postoperative pain relief as soon as pain intensity was greater than 30 on a 100 mm visual analog scale. All patients were evaluated for efficacy and tolerance. Efficacy was evaluated between 15 min and 6 h after the start of the 15 min infusion. RESULTS The most frequently reported adverse event was injection site pain, which was significantly reduced in the new formulation group (i.v. paracetamol 14.7% vs propacetamol 33.0% of children, P = 0.005). No significant difference was obtained between treatments on pain relief (PR), pain intensity difference (PAID) from baseline, and objective pain scale intensity difference (OPSD). Also, treatment effects did not differ significantly for maximum values and weighted sums of PR, PAID (investigator and child rated), OPSD, time to first request for rescue medication, proportion of children requesting rescue medication, and investigators' global treatment satisfaction. CONCLUSION A single infusion of i.v. paracetamol 15 mg.kg(-1) produced analgesia similar to a single infusion of propacetamol 30 mg.kg(-1) following inguinal hernia repair in children. Paracetamol i.v. 15 mg.kg(-1) was better tolerated at the injection site than propacetamol.

Abstract
INTRODUCTION We studied 23 vascular or traumatic head injury subjects, five years after their injury. METHODS Neuropsychological testing included language tests, memory performance, frontal lobe tests and standard tests of intelligence (QI). Behavior was evaluated with the neuropsychiatric interview (NPI). Using an analogic visual scale, subjects performed a self-evaluation of their memory, language, attention, physical and thymic complaints. RESULTS Neuropsychological assessment was heterogeneous but seemed to show severe impairment. Mean NPI score was 31.4: 91 percent of patients showed depression or anxiety and 78 percent of them showed irritability. Mean memory and thymic complaints were scored 6 on the analogic visual scale. Thymic complaint was not correlated with neuropsychological tests but with physical complaints. Thymic complaint was correlated with NPI score. Language complaint was correlated with VIQ, attentional complaint was correlated with PIQ, memory complaint with memory tests. In a second part, we studied 21 patients again 6 months later and 14 patients 1 year later. Mean complaints were scored over 5 after 6 months and over 4 after 1 year. With neuropsychological remediation and social activities, memory complaints improved significantly after 6 months and attentional and thymic complaints after 1 year. CONCLUSION Using of analogical visual scales appears to be feasible: patients were able to evaluate their difficulties. This could be useful to elaborate remediation programs and evaluate outcome.

Abstract
We report the case of a 58 year old male who presented with acute meningoencephalitis and pneumocephalus (intracranial air) visualized on head CT scan. Despite the lack of typical clinical signs such as retroauricular tenderness, red tympanic membrane or otorrhea, mastoiditis was suggested by head CT scan. The patient made a full recovery after mastoidectomy and six weeks of antibiotic therapy. Streptococcus pneumoniae grew from a surgical purulent mastoid tissue sample. Mastoiditis and its complications are rare in adults. A high level of clinical suspicion is needed when a patient presents with encephalitis of unclear origin.

The diagnosis was made a few days later during a laparoscopic exploration owing to the progressive onset of clinical and radiological intestinal obstruction. A large, obstructing subserosal haematoma was found without any apparent perforation of the mucosa, and the damaged loop was resected. Such a complication has already been reported once in the literature after use of a long bevel needle for the puncture. This case is the first reported using an atraumatic short bevel needle. We discuss the technical aspects of the procedure and underline the fact that regional anaesthesia in children is never totally risk free.

Abstract
Insulin was sought during the early postembryonic development of gilt-head sea bream, Sparus aurata, using ultrastructural, immunohistochemical and biochemical techniques. The endocrine pancreas appeared at hatching (Day 0) as a single cluster of morphologically similar cells. Secretory granules formed from Day 1 onwards but the cells could only be identified as insulin-producing B cells at the end of the endotrophic period (Day 3-Day 4). Insulin-immunoreactive cells were detected in the pancreatic primordium from hatching onwards and their number increased after the end of the endo-exotrophic period. Early insulin production was also found using an ELISA method on homogenates of prelarvae and larvae. Insulin levels were fairly high during the endotrophic period, decreased strongly at mouth opening, and then increased at the end of the endo-exocrine period. The origin and role of the large amount of hormone detected during the strictly endotrophic phase of ontogenesis are discussed in light of data on other vertebrates.

Abstract
Structural development and lipid absorption in anterior intestine of gilt-head sea bream Sparus aurata, were studied by light and electron microscopy during three stages of post-embryonic development: (1) the endotrophic period from hatching day (day 0) to mouth opening day (day 3); (2) the endo-exotrophic period from days 3 to 15; (3) the exotrophic period after day 15. During the 2 days following hatching, there was no trace of lipids in intestinal epithelia. Before mouth opening day, the first lipoproteic particles of endogenous origin appeared in entero-cyte endoplasmic reticulum and Golgi apparatus. During the endo-exotrophic period, lipoproteinogenesis increased weakly until day 9, and more greatly between days 9 and 15. It intensified at the beginning of the exotrophic period to remain at a high level afterwards. Until day 15, few transfers of lipoproteins to interenterocyte spaces occurred, whereas no lipoproteins were detectable in the blood flow from days 7 to 9. Their concentration increased slightly between days 9 and 15 to become intense afterwards. Lipid droplets appeared from day 7, and subsisted until the end of endo-exotrophic period. Possible relationships between very low density lipoproteins and chylomicron type lipoproteins and lipid droplets related to lipid excess in food are discussed.

Abstract
One hundred and twenty children have benefited from surgical cure for vesico-renal reflux under loco-regional anesthesia per caudal way, with use of a mixed solution of Lidocaine 1%, Bupivacaine 0.5%, with Adrenaline, along with a complementary narcosis. During the per operative time: the subsequent analgesia and muscular relief have always been excellent and lasted long enough. The hemodynamic status always showed a perfect stability. As to the ventilation, no deleterious effect could be demonstrated. Per operative blooding is reduced and central temperature is more easily controlled. During the post-operative time: the caudal anesthesia has allowed to maintain an efficient analgesia during a mean period of 12 hours which has been considered as sufficient. All the children went quickly back to a normal digestive function. There was no complication relevant to this technique.
