Background/aims: Self-reported food triggers are common in patients with irritable bowel syndrome (IBS) and functional dyspepsia (FD), often leading to dietary restrictions which can be exacerbated by "fear of food." This study aimed to evaluate the frequency of self-reported food triggers and food-related fears in IBS and FD patients and assess their impact on nutrient intake and health-related quality of life (HRQoL).

Methods: Patients meeting Rome IV criteria for IBS or FD, along with healthy controls (HCs), were enrolled.

Functional gastrointestinal disorders, now termed "disorders of gut-brain interaction" (DGBI), are characterized by a spectrum of chronic gastrointestinal symptoms driven by dysregulated gut-brain interaction. DGBIs frequently coexist with liver diseases, including cirrhosis, thereby exacerbating clinical manifestations and complicating management; this overlap is underpinned by shared mechanisms, including gut dysbiosis, increased intestinal permeability, systemic inflammation, and altered neuroimmune signaling. Portal hypertension in cirrhosis promotes small intestinal bacterial overgrowth and microbial translocation, thereby triggering inflammatory pathways that worsen gut and liver function.

Acute-on-chronic liver failure (ACLF) is a condition associated with high mortality in the absence of liver transplantation. There have been various definitions proposed worldwide. The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set in 2004 on ACLF was published in 2009, and the "APASL ACLF Research Consortium (AARC)" was formed in 2012.

This letter critically evaluates Jiang 's article on the differentiation of benign and malignant liver lesions using Emax and platelet count. Despite notable findings, significant methodological and interpretative limitations are identified. The study lacks detailed assay conditions for Emax measurement, employs inadequate statistical methods without robust multivariate analysis, and does not provide clinically relevant threshold values.

Disorders of gut-brain interaction (DGBI), formerly known as functional bowel disorders, encompass a diverse array of conditions and symptoms that may manifest in different parts of the gastrointestinal tract. Some of the most prevalent DGBIs include functional dyspepsia, irritable bowel syndrome, functional constipation, functional diarrhea, and functional bloating and distension. Around 80% of patients with dyspepsia have no identifiable organic cause and are labeled as functional dyspepsia.

Article Synopsis
  • - This letter evaluates the impact of proton pump inhibitors (PPIs) on inflammatory bowel diseases like Crohn's disease (CD) and ulcerative colitis (UC), referencing Liang's review.
  • - It points out that the reliance on mostly cross-sectional and observational studies limits the ability to establish clear causal relationships, compounded by varied patient populations and unclear long-term PPI usage definitions.
  • - The letter stresses the importance of controlling confounding factors and acknowledges potential publication bias, proposing future research directions to improve understanding of PPIs' effects on CD and UC.

  • MAFLD (Metabolic Dysfunction-Associated Fatty Liver Disease) is becoming more common, and it can lead to serious liver problems called MAFLD-ACLF, but what affects patient recovery isn't fully known yet.
  • In a study, researchers looked at data from patients with MAFLD-ACLF to understand their health conditions and see who survived after 90 days, finding that about 51% of patients did survive.
  • They discovered new scoring systems to better predict survival, which included factors like diabetes and the causes of liver damage, and these new scores worked better than older ones.

  • Intravenous corticosteroids are typically used to treat acute severe ulcerative colitis (ASUC), but around 30-40% of patients do not respond well to this treatment.
  • A study examined whether adding tofacitinib to corticosteroids would enhance treatment effectiveness in these patients by conducting a double-blind trial with 104 participants.
  • Results showed that 83% of patients on tofacitinib responded positively to treatment by day 7, compared to 58% on placebo, and those taking tofacitinib had a lower need for rescue therapy over 90 days, indicating better outcomes with the combination therapy.*

The Indian Neurogastroenterology and Motility Association (INMA), earlier named the Indian Motility and Functional Diseases Association developed this evidence-based practice guidelines for the management of irritable bowel syndrome (IBS). A modified Delphi process was used to develop this consensus containing 28 statements, which were concerning diagnostic criteria, epidemiology, etiopathogenesis and comorbidities, investigations, lifestyle modifications and treatments. Owing to the Coronavirus disease-19 (COVID-19) pandemic, lockdowns and mobility restrictions, web-based meetings and electronic voting were the major tools used to develop this consensus.

  • Acute-on-chronic liver failure (ACLF) significantly affects patients with alcoholic hepatitis (AH), with 38.8% mortality observed within 90 days.
  • Research analyzed data from the AARC database, revealing a major portion of patients (82.8%) had ACLF, with corticosteroid treatment improving survival rates for nearly half of the steroid responders.
  • The AARC score effectively predicts patient outcomes, indicating that those with ACLF grade 3 face higher risks of complications and may benefit from early liver transplantation.
