The World Health Organization (WHO) has proposed a plan for the elimination of viral hepatitis with a goal of reducing new hepatitis infections by 30% and 90% in 2020 and 2030, and associated mortality by 10% and 65% respectively. Actions and targets to reach these goals include improving hepatitis B virus (HBV) vaccination programs, the prevention of mother-to-child transmission of HBV, improving the safety of blood products and injections, risk reduction policies and optimizing the diagnosis and treatment of hepatitis. The goal of eliminating hepatitis C virus (HCV) by 2030 is based on three main actions increased screening, strengthening access to care and the prevention of infections and re-infections. But, can this goal be reached? The answer to this question is yes in some countries, perhaps in others and no in most countries. Success will be limited by a "diagnosis burn-out" with 5 times more new viral infections than diagnoses in 2016 and a "treatment burn-out" with cure rates that are 5 times lower than the number of new infections. Nevertheless, France, like 10 other countries, is on track to achieve the WHO elimination plan by 2030. In France, the prioritization of oral antivirals in 2013-2014 which was extended to high-risk populations in 2015 (HIV-infected patients) and 2016 (men who have sex with men, dialyzed or kidney transplant recipients), then in 2017 to universal treatment with full coverage by French national healthcare (10 to 15 000 treatments per year) has resulted in half of the 120 000 patients needed to be treated by 2022 have been treated. Renewed efforts should make it possible to reach the target announced by the French Minister of Health in May 2018 by 2025.Geranylgeranylacetone (GGA), an inducer of heat shock proteins, exerts anticancer activity in some tumours. However, the effect of GGA on human osteosarcoma (OS) has not been reported. This work is designed to evaluate the effect of GGA on the proliferation and apoptosis of human OS cells and to explore the underlying mechanisms. It was found that GGA markedly inhibited the proliferation and induced apoptosis of U-2 OS cells in a dose-dependent manner and also up-regulated the expression of heat shock protein 70 (Hsp70). The degradation and ubiquitination of protein arginine N-methyltransferase 1 (PRMT1) were obviously enhanced in U-2 OS cells with CHIP overexpression and GGA treatment. The expression of PRMT1 was reversed in GGA-treated cell after CHIP knockdown. The turnover of PRMT1 was obviously faster in cells overexpressing CHIP than that in control cells. The methylation and activity of STAT3 were induced by PRMT1, resulting in the inhibition of FAS transcription. Overexpression of PRMT1 reversed the effect of GGA on activation of apoptosis-related proteins and U-2 OS cell apoptosis. The expressions of PRMT1 were significantly up-regulated in OS tissues compared with the adjacent normal tissues and benign bone tumours. In conclusion, GGA promotes the degradation of PRMT1 through the Hsp70-CHIP-mediated proteasome pathway, thereby inducing the FAS-triggered cell apoptosis. Inhibition of PRMT1 may be a potential therapeutic strategy for OS patients.

Hepatocellular adenomas (HCA) rarely occur in males, and if so, are frequently associated with malignant transformation. Guidelines are based on small numbers of patients and advise resection of HCA in male patients, irrespective of size or subtype. This nationwide retrospective cohort study is the largest series of HCA in men correlating (immuno)histopathological and molecular findings with the clinical course.

Dutch male patients with available histological slides with a (differential) diagnosis of HCA between 2000 and 2017 were identified through the Dutch Pathology Registry (PALGA). Histopathology and immunohistochemistry according to international guidelines were revised by two expert hepatopathologists. Next generation sequencing (NGS) was performed to confirm hepatocellular carcinoma (HCC) and/or subtype HCA. Final pathological diagnosis was correlated with recurrence, metastasis and death.

A total of 66 patients from 26 centres fulfilling the inclusion criteria with a mean (±SD) age of 45.0±21.6years were included. check details The diagnosis was changed after expert revision and NGS in 33 of the 66 patients (50%). After a median follow-up of 9.6years, tumour-related mortality of patients with accessible clinical data was 1/18 (5.6%) in HCA, 5/14 (35.7%) in uncertain HCA/HCC and 4/9 (44.4%) in the HCC groups (P=.031). Four B-catenin mutated HCA were identified using NGS, which were not yet identified by immunohistochemistry and expert revision.

Expert revision with relevant immunohistochemistry may help the challenging but prognostically relevant distinction between HCA and well-differentiated HCC in male patients. NGS may be more important to subtype HCA than indicated in present guidelines.

Human muscle biopsies and mouse models of NF1 deficiency in muscle show intramyocellular lipid accumulation, and preclinical data have indicated that L-carnitine supplementation can ameliorate this phenotype. The aim of this study is to examine whether daily L-carnitine supplementation is safe and feasible, and will improve muscle strength and reduce fatigue in children with NF1. A 12-week Phase 2a trial was conducted using 1000 mg daily oral levocarnitine tartrate supplementation. Recruited children were between 8 and 12 years old with a clinical diagnosis of NF1, history of muscle weakness and fatigue, and naïve to L-carnitine. Primary outcomes were safety (self-reporting, biochemical testing) and compliance. Secondary outcomes included plasma acylcarnitine profiles, functional measures (muscle strength, long jump, handwriting speed, 6-minute-walk test [6MWT]), and parent-reported questionnaires (PedsQL™, CBCL/6-18).
