The efficacy of the sulforaphane derivative JY4 was evaluated in acute and chronic mouse models of ulcerative colitis induced by dextran sodium sulfate. Oral administration of JY4 led to significant improvements in symptoms, with recovery of body weight and colorectal length, together with reduced diarrhoea, bloody stools, ulceration of colonic tissue and infiltration of inflammatory cells. The oral bioavailability of JY4, determined by comparing oral dosing with injection into the tail vein, was 5.67%, which was comply with the idea in the intestinal function. Using a dual-luciferase reporter assay, immunofluorescence studies, western blot analysis and immunohistochemical staining, JY4 was shown to significant interfere with the NF-κB-p65 signaling pathway. By preventing the activation of NF-κB-p65, JY4 inhibited the overexpression of downstream inflammatory factors, thereby exerting an anti-inflammatory effect on the intestinal tract. This study thus provides a promising candidate drug, and a new concept for the treatment of ulcerative colitis.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) is the presence of somatic mutations in myeloid and lymphoid malignancy genes in the blood cells of individuals without a hematologic malignancy. Inflammation is hypothesized to be a key mediator in the progression of CHIP to hematologic malignancy and patients with CHIP have a high prevalence of inflammatory diseases. This study aimed to identify the prevalence and characteristics of CHIP in patients with inflammatory bowel disease (IBD).

Background And Aims: Radiological imaging is crucial for diagnosing and monitoring patients with inflammatory bowel diseases (IBD). With increasing awareness of radiation risks, imaging doses should be 'as low as reasonably achievable', with a risk level that one should try to stay underneath 75 mSv. However, real-world data on cumulative exposure are limited.

Goals: We sought to understand the clinical course and risk of dysplasia in persons with UC who achieve near or complete normalization of histology.
Background: Histologic remission and normalization in ulcerative colitis (UC) is associated with improved clinical outcomes. We sought to understand the clinical course and risk of dysplasia in persons with UC who achieve near or complete normalization of histology.

Background: Although the precise cause of the co-occurrence of pyoderma gangrenosum (PG) and inflammatory bowel disease (IBD) is still unknown, prior research has shown that the two conditions coexist. Moreover, it is currently unknown how immune cells function in influencing the relationship between IBD and PG.
Methods: In order to choose independent single nucleotide polymorphism (SNP) as instrumental variables, we were provided with genome-wide association study (GWAS) summary data of European populations from the IEU OpenGWAS project (for IBD) and a the FinnGen database (for PG) publically available.

Purpose Of Review: This review aims to explain the causes, diagnosis, and treatment of malnutrition in hospitalized patients with inflammatory bowel disease (IBD), focusing on both adults and children.
Recent Findings: Malnutrition is common among IBD patients, affecting up to 85% of individuals, and is linked to higher rates of illness, death, and longer hospital stays. Recent studies highlight the importance of early detection using tools like the Subjective Global Assessment (SGA) and handgrip strength tests.
