#1
JOURNAL ARTICLE
Alexandra N Willauer, Kenneth E Sherman
PURPOSE OF REVIEW: Infection with hepatitis E virus (HEV) is a global health concern, yet a clinically underdiagnosed cause of acute and chronic hepatitis. The WHO estimates that 20 million people are infected with HEV annually, yet the epidemiology, diagnosis and prevention remain elusive in many clinical settings. RECENT FINDINGS: Orthohepevirus A (HEV-A) genotypes 1 and 2 cause acute, self-limited hepatitis through faecal-oral transmission. In 2022, the first-ever vaccine campaign was implemented as a response to an HEV outbreak in an endemic region...

JOURNAL ARTICLE
Tiangang Li, John Y L Chiang
PURPOSE OF REVIEW: This review aims to provide a concise update on recent advances in understanding of the bile acid metabolism and signaling in health and diseases. RECENT FINDINGS: CYP2C70 has been identified as the murine cytochrome p450 enzyme that mediates the synthesis of muricholic acids to account for the major different bile acid composition between human and mice. Several studies have linked nutrient sensing bile acid signaling to the regulation of hepatic autophagy-lysosome activity, an integral pathway of the cellular adaptive response to starvation...

JOURNAL ARTICLE
Foong Way David Tai, Reena Sidhu
PURPOSE OF REVIEW: Intrabdominal adhesions and intestinal hernias are the commonest cause of small bowel obstruction. Small bowel diseases, which cause small bowel obstruction, are rarer and often poses a challenge to gastroenterologists to diagnose and treat. In this review, small bowel diseases, which predispose to small bowel obstruction, are focused on, and their challenges in diagnosis and treatment. RECENT FINDINGS: Diagnosis of causes of partial small bowel obstruction is improved with computed tomography (CT) and magnetic resonance (MR) enterography...

JOURNAL ARTICLE
Anupam Rej, Hugo A Penny
PURPOSE OF REVIEW: Diet appears to trigger symptoms in the majority of individuals with irritable bowel syndrome (IBS) and is associated with a reduced quality of life. There has been a recent focus on the role of dietary therapies to manage individuals with IBS. The aim of this review is to discuss the utility of traditional dietary advice (TDA), low-FODMAP diet (LFD) and gluten-free diet (GFD) in IBS. RECENT FINDINGS: Several recent randomized controlled trials (RCTs) have been published demonstrating the efficacy of the LFD and GFD in IBS, with the evidence base for TDA being predominantly based on clinical experience, with emerging RCTs evaluating TDA...

JOURNAL ARTICLE
Hasan Saleh, Leigh Ann K Seaman, William C Palmer
PURPOSE OF REVIEW: Iron overload disorders such as hemochromatosis involve unregulated absorption of dietary iron, leading to excessive iron accumulation in multiple organs. Phlebotomy is the standard of care for removal of excess iron, but dietary modification is not standardized in practice. The purpose of this article is to help standardize hemochromatosis diet counseling based on commonly asked patient questions. RECENT FINDINGS: The clinical benefit regarding dietary modification in iron overload patients is limited due to lack of large clinical trials, but preliminary results are promising...

REVIEW
Michele Malaguarnera, Vito Emanuele Catania, Mariano Malaguarnera
PURPOSE OF REVIEW: Carnitine is an essential micronutrient that transfer long-chain fatty acids from the cytoplasm into the mitochondrial matrix for the β-oxidation. Carnitine is also needed for the mitochondrial efflux of acyl groups in the cases wherein substrate oxidation exceeds energy demands. RECENT FINDINGS: Carnitine deficiency can affect the oxidation of free fatty acids in the mitochondria resulting in the aggregation of lipids in the cytoplasm instead of entering the citric acid cycle...

JOURNAL ARTICLE
Ronald L Koretz
PURPOSE OF REVIEW: The association of malnutrition and a poor prognosis does not prove that providing nutrition support improves that prognosis. The proof of such efficacy requires its demonstration in well designed and executed randomized trials. A systematic review of 40 such trials in 2014 failed to make such a finding. The purpose of this work is to update that review. RECENT FINDINGS: A search of multiple databases identified 12 new trials (3 of enteral nutrition and 9 of nutritional supplements) comparing the nutritional intervention to standard care...

REVIEW
Holmfridur Helgadottir, Mette Vesterhus
PURPOSE OF REVIEW: Liver fibrosis is highly associated with disease progression and clinical outcome in primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC), the major chronic biliary diseases in adults. Establishment of validated tools for the noninvasive evaluation of liver fibrosis in PBC and PSC for use in patient follow-up, and effect evaluation in clinical trials, has been a top research priority over recent years. RECENT FINDINGS: Two studies in large PBC patient panels investigated liver stiffness measurement by vibration-controlled transient elastography (VCTE) and two studies in PSC demonstrated enhanced liver fibrosis (ELF) variation over time, confirming VCTE and ELF as good prognostic markers...

REVIEW
Pauline Iorio, Quentin Vanderbecq, Sanaâ El Mouhadi, Lionel Arrivé
PURPOSE OF REVIEW: Magnetic resonance cholangiopancreatography (MRCP) has become the reference examination for the exploration of the biliary tract and has replaced endoscopic cholangiography for the analysis of the biliary tract because of its equivalent performance and its noninvasive character. RECENT FINDINGS: Based on the International Primary Sclerosing Cholangitis (PSC) Study Group recommendations for MR imaging in PSC, two protocols can be distinguished for the imaging of biliary tract: a basic protocol and a more complete protocol...
