Fiber supplementation is widely used and recommended for irritable bowel syndrome (IBS), however there is no recent evidence synthesis. We aimed to investigate the efficacy of fiber supplements in IBS through a systematic review and meta-analysis of randomized controlled trials.

The proliferation of hepatocytes is essential for liver regeneration. Hepatocytes harbor supernumerary centrosomes, which can lead to multipolar spindles, chromosome misalignment and prolonged mitosis. How hepatocytes overcome these mitotic challenges to efficiently regenerate is unclear.

Gallbladder stones represent a common gastrointestinal disorder influenced by various metabolic and lifestyle-related risk factors. Serum uric acid (UA), a byproduct of purine metabolism, has been suggested as a potential contributor to gallstone formation, but the association remains unclear. This study aimed to investigate the relationship between serum UA levels and gallbladder stone prevalence in Korean women.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major cause of chronic liver disease. N-acetylcysteine (NAC) has demonstrated antioxidant and hepatoprotective effects in non-alcoholic steatohepatitis. This study evaluated the impact of high-dose NAC on oxidative stress, insulin resistance, and liver-related outcomes in non-diabetic MASLD patients.

Predicting outcomes of primary sclerosing cholangitis (PSC) by reliable and simple tools is an unmet need. Retrospective studies have suggested that liver stiffness measurement (LSM) by vibration-controlled transient elastography (FibroScan, Echosens) can predict outcomes. We aimed to validate the prognostic value of LSM statics and determine the relevance of LSM dynamics in a large, prospective, cohort study.

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are widely used in psychiatry for mood and anxiety disorders but remain underexplored in chronic gastrointestinal conditions such as inflammatory bowel disease (IBD) and disorders of gut-brain interaction (DGBI). This review synthesizes emerging evidence on their potential therapeutic role, focusing on shared neurobiological and immunometabolic mechanisms within the bidirectional microbiota-gut-brain axis. We reviewed preclinical and clinical studies investigating SSRIs and SNRIs in IBD and DGBI, emphasizing neuroimmune, enteric, and microbial pathways relevant to disease modulation. SSRIs and SNRIs inhibit serotonin (SERT) and norepinephrine (NET) transporters, increasing central 5-HT and NE signaling across corticolimbic and autonomic networks. These effects enhance neuroplasticity and BDNF activity, reduce microglial activation and proinflammatory cytokines, and partially normalize hypothalamic-pituitary-adrenal (HPA) axis reactivity. Peripherally, epithelial, and enteric SERT blockade elevates luminal 5-HT, activating 5-HT<inf>3</inf> and 5-HT<inf>4</inf> receptors that promote motility, secretion, and sensory modulation. Both classes also enhance vagal antiinflammatory tone and tighten epithelial barrier integrity by suppressing nuclear factor kappa (NF-κB) signaling and increasing interleukin 10 (IL-10). Through integrated central, enteric, and immune actions, SSRIs and SNRIs can influence mood, pain perception, gut motility, and mucosal inflammation, key determinants of symptom burden in IBD and DGBI. SSRIs and SNRIs hold promise as multimodal modulators of the microbiota-gut-brain axis, bridging psychiatric and gastroenterological care. However, mechanistic preclinical studies and rigorously designed, adequately powered randomized trials are needed to define causal pathways, optimal dosing, and patient stratification strategies.

Escherichia coli Nissle (EcN) 1917 is a Gram-negative bacterium currently used as probiotic in the management of infectious gastroenteritis and ulcerative colitis (UC). We evaluated the effect of administration of EcN on the composition of the gut microbiota and on intestinal permeability in patients affected by UC.

Colorectal cancer (CRC) exhibits high morbidity and mortality globally among malignant tumors. Early diagnosis and treatment can improve prognosis. Previously, tumor size was considered correlated with colorectal cancer invasion. However, whether small CRCs exhibit lower aggressiveness remains uncertain. To investigate the endoscopic features and risk factors for deep submucosal invasion in early, non-pedunculated CRCs with a diameter < 2 cm, and to establish a preliminary nomogram to inform clinical diagnosis and treatment.
