Randomized Sham Controlled Trial of Translumbosacral Neuromodulation Therapy for Fecal Incontinence
May 9, 2026
The authors aimed to evaluate the efficacy and safety of translumbosacral neuromodulation therapy (TNT) for treating fecal incontinence (FI) in a randomized sham-controlled trial. Results indicated that both 2400 and 3600 magnetic pulse treatments significantly reduced weekly FI episodes and improved bowel symptoms compared to sham treatment, with no serious adverse events reported, demonstrating that TNT is a promising non-invasive option for FI management.
Neutrophil-Driven Trogocytosis in PDAC Liver Metastases Restrains Immunosuppressive Macrophage Polarization and Limits Metastatic Progression
May 8, 2026
This study investigates the role of neutrophils in modulating the immune landscape of pancreatic ductal adenocarcinoma (PDAC) liver metastases, specifically how they influence macrophage polarization. The authors found that neutrophils, through trogocytosis, present tumor cell fragments to macrophages, suppressing the development of immunosuppressive macrophages and enhancing anti-tumor signaling pathways. These findings suggest that targeting neutrophil-macrophage interactions could be a promising therapeutic strategy in metastatic PDAC.
Blockade of Tumor TAK1 Induces DNA Damage and Immunogenic cGAS-STING Pathway Activation in Pancreatic Cancer
May 3, 2026
The authors investigate the role of TGF-β-activated kinase 1 (TAK1) in pancreatic ductal adenocarcinoma (PDAC) and its impact on T cell dysfunction within the tumor microenvironment. They demonstrate that inhibiting TAK1 enhances T cell infiltration and activates the cGAS-STING pathway, leading to DNA damage and inflammatory responses that could sensitize PDAC to immune checkpoint blockade therapy. This study identifies TAK1 as a potential therapeutic target for reversing the immunologically "cold" nature of PDAC.
Bioengineering a probiotic to bloom during colonic inflammation promotes reliable efficacy in translational models of colitis
May 1, 2026
The authors aimed to determine whether bioengineering E. coli Nissle 1917 (EcN) with the ttr operon (EcN::ttr) could enhance its effectiveness in treating colitis by allowing it to thrive during intestinal inflammation. Their findings demonstrated that EcN::ttr significantly improved colitis outcomes compared to both EcN and standard treatments, promoting immunoregulatory responses and beneficial changes in the gut microbiome. This study suggests that EcN::ttr could serve as a novel microbiome therapeutic for inflammatory bowel diseases (IBD).
Recommendations for the Evaluation and Management of Inflammatory Bowel Disease with Irritable Bowel Syndrome-Like Symptoms: A Joint Rome Foundation and International Organization for the Study of IBD (IOIBD) Consensus
May 1, 2026
The authors aimed to establish standardized recommendations for the evaluation and management of inflammatory bowel disease (IBD) patients who exhibit symptoms resembling irritable bowel syndrome (IBS). Through a consensus process involving a multidisciplinary panel, they defined appropriate terminology, diagnostic criteria, and treatment strategies, ultimately proposing the term "IBD with IBS-like symptoms" and endorsing various therapeutic approaches. This consensus seeks to enhance clinical management and inform future research in this area.
Chronic Pancreatitis: Mechanisms of Inflammation, Pathways of Progression and Emerging Therapeutic Strategies
Apr 29, 2026
The authors investigate the mechanisms of inflammation and pathways of progression in chronic pancreatitis, a disease characterized by recurrent abdominal pain and pancreatic dysfunction. They highlight the challenges in early diagnosis due to a lack of validated biomarkers and the need for improved therapeutic strategies that can modify disease progression. The review emphasizes the importance of developing a patient-tailored approach to therapy that targets inflammation and preserves pancreatic function.
Design of Treatment Trials for Disorders of Gut-Brain Interaction
Apr 24, 2026
The authors aim to address the challenges and methodologies involved in designing treatment trials for disorders of gut-brain interaction (DGBI), particularly given the predominance of research focused on irritable bowel syndrome in adults. They discuss the evolution of trial designs, including the incorporation of dietary and behavioral therapies, and emphasize the importance of validated patient-reported outcomes and adherence to clinical standards to improve treatment strategies for these complex disorders. The article serves as a comprehensive guide on best practices for conducting and reporting DGBI treatment trials.
Functional Esophageal Disorders
Apr 24, 2026
The authors investigate the underlying mechanisms of functional esophageal disorders, which present symptoms like heartburn and dysphagia without structural abnormalities. They propose that visceral hypersensitivity and altered neuropsychological processing contribute to these symptoms, and emphasize the need for further research into the neurobiological factors involved to develop more effective treatments.
Biopsychosocial Aspects of Adult and Pediatric Disorders of Gut-Brain Interaction
Apr 24, 2026
This review addresses how to effectively care for patients with disorders of gut-brain interaction (DGBI) by exploring the biopsychosocial framework that influences these conditions. The authors aim to provide evidence-based psychosocial assessment and management strategies for both adult and pediatric populations, while also offering recommendations for training healthcare providers in this area. Ultimately, the review highlights the significance of understanding the brain-gut axis and enhancing the patient-provider relationship to improve clinical outcomes.
Fundamentals of Neurogastroenterology: Basic Science
Apr 24, 2026
This review aims to synthesize recent advancements in neurogastroenterology since the Rome IV criteria, particularly focusing on the complex mechanisms underlying disorders of gut-brain interaction (DGBI). The authors explore how various biological systems interact and contribute to DGBI, while also discussing the potential for new therapeutic strategies informed by these scientific insights. Key themes include brain-gut interactions, neuroplasticity, and the role of the microbiome, all of which are essential for understanding and treating these multifactorial disorders.
