Macrovesicular steatosis (MS) is a major risk factor for liver graft failure after transplantation and pathological microscopic examination of a frozen tissue section remains the gold standard for its assessment. However, the latter requires an experienced in-house pathologist for correct and rapid diagnosis as well as specific equipment that...

In this contribution, delivered after more than one month of nationwide lockdowns of European countries, we discuss side-effects of the COVID-19 pandemic on citizens' access to medical care and the efficiency of national health systems in care provision. In the first section, we stress the importance of indirect mortality, i.e. non-diagnosis of...

Background: Protein malnutrition and bacterial overgrowth occurring after bariatric surgery (BS) might cause severe liver failure (LF) needing liver transplantation (LT).Objectives: To evaluate indications and outcomes of LT for BS-related LF.Setting: University hospital in France.Methods: The EMBASE, MEDLINE, and COCHRANE central databases...

Significant aspects of COVID-19 pandemic remain obscure. Angiotensin converting enzyme 2 (ACE2), a component of the renin-angiotensin system, whose expression dominates on lung alveolar epithelial cells, is the human cell receptor of SARS-CoV-2, the causative agent of COVID-19. We strongly encourage the concept that thorough considerations of...

There is increasing evidence that ACE2 gene polymorphism can modulate the interaction between ACE2 and the SARS-CoV-2 spike protein affecting the viral entry into the host cell, and/or contribute to lung and systemic damage in COVID-19. Here we used in silico molecular docking to predict the effects of ACE2 missense variants on the interaction...

Background: While metabolic health in obesity may confer a protective status, recent studies indicate that nonalcoholic fatty liver disease (NAFLD) or even nonalcoholic steatohepatitis (NASH) may exist in this category of individuals. Although cardiovascular and diabetic risks have been well described, the risk of NAFLD and NASH among this...

Liver vessel segmentation from routinely performed medical imaging is a useful tool for diagnosis, treatment planning and delivery, and prognosis evaluation for many diseases, particularly liver cancer. A precise representation of liver anatomy is crucial to define the extent of the disease and, when suitable, the consequent resective or...

BACKGROUND: Bile duct injuries (BDIs) sustained during a cholecystectomy still remain a major surgical problem, and it is still not clear whether the injury should be repaired immediately or a delayed repair is preferred. METHODS: A retrospective national French survey was conducted to compare the results of immediate (at time of...

Although Roux-en-Y gastric bypass (RYGBP) is one of the preferred bariatric procedures in obese individuals, the efficacy of this procedure in the setting of super-obesity [body mass index (BMI) >/=50] is unclear. The aim of this study was to compare the efficacy of laparoscopic (L) RYGBP to reverse metabolic syndrome, inflammation, and insulin...

Background. Increasing evidence suggests that apoptosis plays a critical role in ischemia reperfusion (IR)-mediated liver injury. Clotrimazole (CTZ) is a potent antimycotic drug that also has a free radical scavenger activity. This study investigated the possible anti-apoptotic, pro-survival role of CTZ in hepatic IR injury in rats. Methods....

In this study, we explored in a prospective cohort of morbidly obese women undergoing laparoscopic Roux-en-Y gastric bypass (LRYGP) correlations between baseline anthropometrics, metabolic parameters, resting energy expenditure (REE), body composition, and 1-year % excess body mass index loss (%EBMIL). We also investigated risk factors for...

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is currently the most common bariatric procedure and results in a substantial weight loss and recovery from obesity-related comorbidities, both of which are maintained in the long term. However, besides the desired loss of fat mass, LRYGBP is also followed by the loss of fat-free mass (FFM). We...
