Hepatitis B Delta: assessment of the knowledge and practices of hepato-gastroenterologists practicing in non-academic settings in France.

Background: Data on the management of Hepatitis B-Delta (HB-D) by hepatogastroenterologists (HGs) practicing in nonacademic hospitals or private practices are unknown in France.

Objective: We aimed to evaluate the knowledge and practices of HGs practicing in nonacademic settings regarding HB-D.

Methods: A Google form document was sent to those HGs from May to September 2021.

Early detection of liver injuries by the Serum enhanced binding test sensitive to albumin post-transcriptional modifications.

Early and sensitive biomarkers of liver dysfunction and drug-induced liver injury (DILI) are still needed, both for patient care and drug development. We developed the Serum Enhanced Binding (SEB) test to reveal post-transcriptional modifications (PTMs) of human serum albumin resulting from hepatocyte dysfunctions and further evaluated its performance in an animal model. The SEB test consists in spiking serum ex-vivo with ligands having specific binding sites related to the most relevant albumin PTMs and measuring their unbound fraction.

Liver disease in germline mutations of telomere-related genes: Prevalence, clinical, radiological, pathological features, outcome, and risk factors.

Background And Aim: Germline mutations of telomere-related genes (TRG) induce multiorgan dysfunction, and liver-specific manifestations have not been clearly outlined. We aimed to describe TRG mutations-associated liver diseases.

Approach And Results: Retrospective multicenter analysis of liver disease (transaminases > 30 IU/L and/or abnormal liver imaging) in patients with TRG mutations.

Risk of delayed bleeding after colorectal endoscopic submucosal dissection: the Limoges Bleeding Score.

Background: Clinically significant delayed bleeding (CSDB) is a frequent, and sometimes severe, adverse event after colorectal endoscopic submucosal dissection (ESD). We evaluated risk factors of CSDB after colorectal ESD.

Methods: We analyzed a prospective registry of 940 colorectal ESDs performed from 2013 to 2022.

Towards hepatitis C elimination in France: Scanvir, an effective model to test and treat drug users on dedicated days.

According to the French recommendations, the elimination of the hepatitis C virus by 2025 could be a realistic public health goal. Screening policies are being intensified, and access to treatment is promoted for patients who escape the usual care pathway. The 'Scanvir' program is an original strategy based on dedicated screening days, as part of the 'test, treat and cure HCV' event in addiction care centers in a French region, during which innovative screening technologies (RDTs, FibroScan® and point-of-care HCV RNA testing) are brought on site and access to a multidisciplinary team is offered.

Iohexol plasma and urinary concentrations in cirrhotic patients: A pilot study.

Background: Renal failure is an independent prognostic factor for survival in patients with cirrhosis. Equations to calculate serum creatinine significantly overestimate the glomerular filtration rate (GFR). Plasma clearance of direct biomarkers has been used to improve the accuracy of evaluations of GFR in this population, but no study has simultaneously measured plasma and urinary clearance, which is the gold standard.

A Hybrid Model Associating Population Pharmacokinetics with Machine Learning: A Case Study with Iohexol Clearance Estimation.

Background: Maximum a posteriori Bayesian estimation (MAP-BE) based on a limited sampling strategy and a population pharmacokinetic model is frequently used to estimate pharmacokinetic parameters in individuals, however with some uncertainty (bias). Recent works have shown that the performance in individual estimation or pharmacokinetic parameters can be improved by combining population pharmacokinetic and machine learning algorithms.

Objective: The objective of this work was to investigate the use of a hybrid machine learning/population pharmacokinetic approach to improve individual iohexol clearance estimation.

A single Bayesian estimator for iohexol clearance estimation in ICU, liver failure and renal transplant patients.

Aims: Iohexol clearance has been proposed to estimate the glomerular filtration rate (GFR). A population pharmacokinetics (popPK) model was developed from heterogeneous patients. A Bayesian estimator (MAP-BE) based on a limited sampling strategy (LSS) was derived and evaluated in external patients.

Alpha-fetoprotein and focal nodular hyperplasia: An unconventional couple.

We report the case of a 36-year-old patient who was initially managed for gynecomastia. The first biological analyses showed a moderately elevated alpha-fetoprotein (AFP) level. After an endocrine etiology was excluded, an abdominal computed tomography scan showed typical focal nodular hyperplasia (FNH) proven by biopsy and showing expression of AFP in FNH cells.

EUS-guided biliary drainage with electrocautery-enhanced lumen-apposing metal stent placement should replace PTBD after ERCP failure in patients with distal tumoral biliary obstruction: a large real-life study.

Aims: In cases of malignant distal biliary obstruction, ERCP is the preferred technique for bile duct drainage. In case of failure, the alternative techniques are percutaneous transhepatic biliary drainage (PTBD) and more recently endoscopic ultrasound-guided biliary drainage. A new type of stent called the electrocautery-enhanced lumen-apposing metal stent (EC-LAMS) has been developed to enable the performance of biliary-enteric anastomosis under EUS-guidance in a single step, without prior bile duct puncture or the need for a guidewire.

Prognostic Risk Classification for Biochemical Relapse-Free Survival in Oligometastatic Recurrent Prostate Cancer Determined by Choline PET.

Background: Choline positron emission tomography/computed tomography (PET/CT) is a new imaging technique for the detection of oligometastatic (OM) prostate cancer. The aim of this study was to evaluate the outcomes after initial OM diagnoses; treatment, particularly metastasis-directed therapy (MDT); and determine risk groups.

Patients And Methods: This multi-center, retrospective study included patients with hormone-sensitive biological relapse after local treatment with curative intent and with fewer than six choline PET/CT metastases.

Subclinical proximal tubulopathy in hepatitis B: The roles of nucleot(s)ide analogue treatment and the hepatitis B virus.

Background: The recommended monitoring tools for evaluating nucleot(s)ide analogue renal toxicity, such as estimated glomerular filtration rate (eGFR) and phosphatemia, are late markers of proximal tubulopathy. Multiple early markers are available, but no consensus exists on their use.

Aim: To determine the 24 mo prevalence of subclinical proximal tubulopathy (SPT), as defined with early biomarkers, in treated untreated hepatitis B virus (HBV)-monoinfected patients.

Double-clip traction could be superior to the pocket-creation method with cylindrical cap for colonic ESD: a randomized study in an ex vivo model.

Introduction: In Western countries, debates between ESD vs piece-meal EMR as the best treatment for large colorectal adenomas persist regarding the difficulty of ESD the colon, and the safety and relatively good results of piece-meal endoscopic mucosal resection (EMR). Pocket-creation method (PCM) and double-clip countertraction (DCT) are two strategies recently published to facilitate ESD in this challenging situation.

Method: This is a randomized animal study to compare PCM and DCT strategies for colonic ESD on ex vivo models (bovine colon) performed by 3 operators novice in ESD.

BDNF levels and liver stiffness in subjects with alcohol use disorder: Evaluation after alcohol withdrawal.

: Brain-derived neurotrophic factor (BDNF) plays a key role in the processes of withdrawal and addiction in alcohol use disorder (AUD), and is also involved in liver homeostasis. The role of BDNF in liver damage and its link with liver stiffness are not known. We hypothesize that serum BDNF levels are linked to changes in hepatic elasticity, both of which depend on variations in alcohol consumption.

Rooibos, a fake friend.

Rooibos is consumed worldwide and its use considered safe. It contains scavengers of free radicals and is so is deemed to be a liver protector. Nevertheless, hepatic toxicity exists even if rare.

Effect of implementing a regional referral network on surgical referral rate of benign polyps found during a colorectal cancer screening program: A population-based study.

Introduction: Surgical management is too often performed as the first-line treatment for large, benign colorectal polyps. We report the management of benign lesions detected by organised colorectal cancer (CRC) screening.

Methods: Population-based study in 2012, 2016, and 2017, analyzing the evolution of surgical management of benign polyps of≥2cm diameter discovered in the context of organised CRC screening after the implementation of a regional referral network for the management of superficial colorectal lesions.

Liver elastometry and alcohol withdrawal: Median-term follow-up in a psychiatric unit.

The measurement of liver stiffness (LS) shows promise as a follow-up tool after alcohol withdrawal, but it has mainly been studied in the early phase or in patients with severe liver disease. A 6-month ancillary study of a specific psychiatric cohort of alcoholic patients without known liver disease followed after withdrawal was conducted (Clinical Trial NCT01491347). Clinical and biological data and LS values were collected every 2 months.

Evaluation of Longitudinal Exposure to Tacrolimus as a Risk Factor of Chronic Kidney Disease Occurrence Within the First-year Post-Liver Transplantation.

Background: Renal failure is predictive of mortality in the early postliver-transplantation period and calcineurin inhibitors toxicity is a main challenge. Our aim is to assess the impact of longitudinal tacrolimus exposure (TLE) and other variables on chronic kidney disease (CKD)-free 1-year-survival.

Methods: Retrospective data of consecutive patients transplanted between 2011 and 2016 and treated with tacrolimus were collected.

Cirrhotic patients and older people.

The global population is aging, and so the number of older cirrhotic patients is increasing. Older patients are characterised by a risk of frailty and comorbidities, and age is a risk factor for mortality in cirrhotic patients. The incidence of non-alcoholic fatty liver disease as an aetiology of cirrhosis is increasing, while that of chronic viral hepatitis is decreasing.

Grafting of an autologous tissue-engineered human corneal epithelium to a patient with limbal stem cell deficiency (LSCD).

Purpose: In this study, we evaluated the feasibility of recovering the corneal surface integrity in a patient suffering from unilateral LSCD through the transplantation of cultured autologous corneal epithelial cells.

Methods: Human corneal epithelial cells (HCECs) were isolated from a limbal biopsy of the contralateral eye of a patient with unilateral LSCD and cultured in monolayer in the presence of an irradiated human fibroblasts feeder layer (iHFL). To produce a cultured autologous corneal epithelium (CACE), HCECs were seeded on a fibrin substrate and maintained in culture until confluence.
