Prophylactic clip closure after endoscopic mucosal resection reduces delayed bleeding in large and proximal colon lesions; however, evidence regarding its effectiveness in colorectal endoscopic submucosal dissection (ESD) is lacking.

The gut microbiota has been linked to non-communicable diseases, including chronic kidney disease (CKD). However, the relationships between gut microbiome composition changes, uraemic toxins (UTs) accumulation, and diet on CKD severity and progression remain underexplored.

Gastrointestinal acute graft-versus-host disease (GI-aGVHD) is one of the main complications of patients undergoing allogenic haematopoietic stem cell transplantation (allo-HSCT). A deeper understanding of the mechanisms of sustaining intestinal homeostasis is essential.

The intricate interplay between the gut microbiota and the GI tract has garnered significant attention, as growing evidence has identified the inflammasome as a crucial yet underexplored master regulator in microbiota-driven diseases. Triggered by a variety of dangers, inflammasomes are supramolecular complexes that regulate immune response. A large number of bacterial-derived inducers have been characterised so far. Although structurally divergent, threats are neutralised by the inflammasome, which is then classified into three families: (1) nucleotide-binding oligomerisation domain, leucine-rich repeat-containing proteins, (2) absent in melanoma 2-like receptors and (3) pyrin. An unbalanced microbiota composition, expressed by a dysbiotic phenotype, might therefore induce undesired inflammasome activation, altering the local host homeostasis. Recent studies on the 'microbiota-inflammasome axis' have uncovered unexpected roles for inflammasome signalling in various types of GI cancer and IBD. Additionally, beyond local gut functions, microbiota influences stress responses and neurological health through aberrant secretion of inflammasome-processed cytokines, linking gut-derived signals to systemic diseases via the vagus nerve and the hypothalamic-pituitary-adrenal axis. Besides the standard experimental approaches, this complex network of interactions is now being addressed by Artificial intelligence, which emphasises the profound impact of the gut microbiota on GI health, cancer progression and brain function, opening new avenues for therapeutic intervention in GI diseases, cancer and neurological disorders. Ultimately, microbiota-inflammasome interactions manage a regulatory framework that influences inflammation, cancer progression and systemic diseases, positioning it as both a mediator and a promising therapeutic target in GI malignancies and systemic diseases of the central nervous system.

Complications of endoscopic mucosal resection (EMR) of large colorectal polyps remain a concern.

Despite the long-standing recommendations of high-protein diets for patients with cancer, the precise mechanisms of this dietary approach in benefiting tumour suppression and enhancing sensitivity to chemotherapy remain elusive.
