Mechanisms underlying changes in intestinal permeability during pregnancy and their implications for maternal and infant health.

Proper regulation of intestinal permeability is essential for maintaining the integrity of the intestinal mucosal barrier. An abnormal increase in permeability can significantly contribute to the onset and progression of various diseases, including autoimmune disorders, metabolic conditions, allergies, and inflammatory bowel diseases. The potential connection between intestinal permeability and maternal health during pregnancy is increasingly recognized, yet a comprehensive review remains lacking.

Familial Mediterranean fever with sigmoid colon stricture.

We describe a case of familial Mediterranean fever (FMF) with sigmoid colon stricture. The patient, a woman in her 30 s, had a 12-year history of ileocolitis-type Crohn's disease. The colonoscope could not pass because of the sigmoid colon stricture, and the patient was referred to our hospital with complaints of abdominal pain and fever.

[Treatment of severe flares in Crohn's disease and ulcerative colitis].

Background: In chronic inflammatory bowel diseases (IBD), severe flares are characterized by intense inflammatory activity and a high disease burden for patients. Treatment addresses both short-term goals (e.g.

Joint analysis of genome-wide cross-trait and multi-omics reveals molecular mechanisms of inflammatory bowel disease and nominates its novel therapeutic genes.

Inflammatory bowel disease (IBD) with the two predominant endophenotypes-Crohn's disease (CD) and ulcerative colitis (UC)-represents a group of chronic gastrointestinal inflammatory conditions. Since most genetic associations with IBD are often limited to independent subtypes, we reported a genome-wide association study (GWAS) cross-trait analysis combined with CD and UC to enhance statistical power. Initially, we detected 256 association signals at 54 genomic susceptibility loci and further characterized the functionality of variants within these regions.

Determining the accuracy and interobserver agreement of four ultrasound scores in Crohn's disease assessment: correlations with endoscopy.

Background: Gastrointestinal ultrasound (GIUS) is recommended for monitoring Crohn's disease (CD). GIUS scores are used to quantify CD activity. Among them, IBUS-SAS (International Bowel Ultrasound Segmental Activity Score), BUSS (Bowel Ultrasound Score), Simple-US (Simple Ultrasound Score), and SUS-CD (Simple Ultrasound Score for Crohn's Disease) are most commonly used.

Identification of Biomarkers Related to Liquid-Liquid Phase Separation for Ulcerative Colitis Based on Single-Cell and Bulk RNA Transcriptome Sequencing Data.

Background: Liquid-Liquid Phase Separation (LLPS) is a process involved in the formation of established organelles and various condensates that lack membranes; however, the relationship between LLPS and Ulcerative Colitis (UC) remains unclear.

Aims: This study aimed to comprehensively clarify the correlation between ulcerative colitis (UC) and liquid-liquid phase separation (LLPS).

Objectives: In this study, bioinformatics analyses and public databases were applied to screen and validate key genes associated with LLPS in UC.

Development and Examination of an Educational Program Combining E-Learning and Face-to-Face Training That Nurtures Inflammatory Bowel Disease Nurse Specialists.

Introduction: The number of patients with inflammatory bowel disease (IBD) in Japan has continued to increase, leading to diverse and complex patient backgrounds. Despite these challenges, the education of IBD nurse specialists has not kept pace with the evolving circumstances. Therefore, our research aimed to develop and validate an educational program for the training of IBD nurse specialists.

Malakoplakia Associated with Diarrhoea and Colonic Lesions After Rituximab Treatment.

Unlabelled: Malakoplakia is a rare granulomatous condition that occurs due to defective lysosomal digestion during phagocytosis and can mimic inflammatory bowel disease (IBD) or malignancies, particularly in immunosuppressed patients. We report the case of a 62-year-old male with IgG4-related orbitopathy, who developed persistent diarrhoea and colonic lesions 6 weeks after receiving rituximab therapy for nephrotic syndrome secondary to membranoproliferative glomerulonephritis. Colonoscopy revealed pancolitis with mucosal granularity, loss of vascular pattern, and small nodules, raising initial suspicion for IBD.

Thiamine-Reduced Fatigue in Quiescent Inflammatory Bowel Disease Is Linked to Abundance.

Background And Aims: Chronic fatigue is common in patients with inflammatory bowel disease (IBD). The gut microbiota, specifically, microbial diversity and butyrate-producing bacteria have been linked to the fatigue pathogenesis. High-dose oral thiamine reduces fatigue, potentially through gut microbiota modification.

The efficacy and feasibility of lifestyle interventions on modifiable cardiovascular disease risk factors among people with inflammatory bowel disease.

This review aims to highlight the relative importance of cardiovascular disease (CVD) lifestyle-associated risk factors among individuals with inflammatory bowel disease (IBD) and examine the effectiveness of lifestyle interventions to improve these CVD risk factors. Adults with IBD are at higher risk of CVD due to systemic and gut inflammation. Besides that, tobacco smoking, dyslipidaemia, hypertension, obesity, physical inactivity and poor diet can also increase CVD risk.

Does the Failure to Provide Equitable Access to Treatment Lead to Action by NHS Organisations? The Case of Biologics for South Asians with Inflammatory Bowel Disease.

The purpose of this study was to identify whether NHS Trusts where discrimination in the delivery of care to patients from the South Asian community had been demonstrated had taken any actions to address the issue over the subsequent year. Freedom of information requests were sent to three trusts which had provided evidence of disparate provision of biologic therapy to patients with Crohn's disease, their associated Clinical Commissioning Groups and Healthwatch organisations to seek evidence whether they had remedied the situation. Requests were also sent to the Care Quality Commission, NHS Improvement and the Equality and Human Rights Commission seeking examples where they had responded to inequitable delivery of care related to ethnicity.

Crohn's disease, irritable bowel syndrome, and chronic fatigue: the importance of communication and symptom management-a case report.

Background: Crohn's disease and irritable bowel syndrome may both cause abdominal pain and diarrhea. Irritable bowel syndrome not only is an important differential diagnosis for Crohn's disease but also occurs in one out of three patients with Crohn's disease in remission in parallel. If not adequately diagnosed and treated, additional functional symptoms such as fatigue and/or muscle pain may develop, indicating a more severe course.

Chronic active Epstein‒Barr virus colitis, a rare cause of recurrent diarrhea in an immunocompetent female: a case report.

Background: Chronic active Epstein-Barr virus (CAEBV) colitis is a rare disease with clinical and endoscopic manifestations very similar to those of inflammatory bowel disease (IBD). In clinical practice, it is easy to be misdiagnosed and mistreated, leading to poor clinical outcomes.

Case Presentation: We report a case of a 56-year-old Chinese woman who presented with 6 years of intermittent severe diarrhea, fever, and abdominal pain.

Taurine prevents mitochondrial dysfunction and protects mitochondria from reactive oxygen species and deuterium toxicity.

Taurine, although not a coding amino acid, is the most common free amino acid in the body. Taurine has multiple and complex functions in protecting mitochondria against oxidative-nitrosative stress. In this comprehensive review paper, we introduce a novel potential role for taurine in protecting from deuterium (heavy hydrogen) toxicity.

Change in fatigue in patients with ulcerative colitis or Crohn's disease initiating biologic therapy.

Background: Fatigue is common among patients with inflammatory bowel diseases (IBDs) and is associated with decreased quality of life (QoL).

Aims: Describe fatigue evolution and identify factors associated with fatigue outcomes in patients with ulcerative colitis (UC) or Crohn's disease (CD) initiating biologic treatment.

Methods: Data from adult Belgian patients with UC or CD enrolled in a prospective real-world study were utilized.

Maintenance treatment with vedolizumab in paediatric inflammatory bowel disease (VEDOKIDS): 54-week outcomes of a multicentre, prospective, cohort study.

Background: Infliximab and adalimumab are the only biologics thus far approved for paediatric patients with inflammatory bowel disease (IBD), so other biologics, such as vedolizumab, are prescribed off-label. Despite its frequent use, prospective data for vedolizumab treatment in children are available only for short-term induction outcomes. We aimed to evaluate the long-term efficacy and safety of maintenance therapy with vedolizumab in paediatric patients with IBD.

Linking E. coli to fibrosis in Crohn's disease.

Intestinal fibrosis associated with Crohn's disease is a serious yet poorly understood clinical complication. In this issue of Cell Host & Microbe, Ahn and colleagues provide evidence that the adherent intestinal E. coli produced the metallophore yersiniabactin, which sequesters zinc to drive intestinal fibrosis in a HIF-1α-dependent manner.

Ribosomal proteins mediate non-canonical regulation of gut inflammatory signature by crop contaminant deoxynivalenol.

Deoxynivalenol (DON), a prevalent mycotoxin produced by Fusarium species, contaminates global agricultural products and poses significant health risks, particularly to the gastrointestinal (GI) system. DON exposure disrupts ribosomal function, inducing stress responses linked to various inflammatory diseases, including inflammatory bowel disease (IBD). In this study, we elucidate a novel regulatory mechanism involving ribosomal proteins (RPs) RPL13A and RPS3, which mediate proinflammatory chemokine production in DON-exposed gut epithelial cells.

Health-Care Utilization of Children Born to Women with and Without Inflammatory Bowel Disease in the First Five Years of Life: A Population-Cohort Study.

Background: Children born to women with inflammatory bowel disease (IBD) may have increased healthcare utilization in early life due to genetic susceptibilities and exposure to inflammation in utero, though this has not been robustly evaluated. We aimed to characterize healthcare use between these groups.

Methods: We accessed province-wide health administrative databases to identify children born to women with and without IBD between 2002-2019.

Increased Medication Utilization Precedes Incidentally Diagnosed Inflammatory Bowel Disease: A Multicenter, Case-Control Study.

This study investigates whether subclinical inflammation in asymptomatic patients with inflammatory bowel disease (IBD) leads to increased medication use. In a multicenter, retrospective analysis of patients diagnosed with incidental ulcerative colitis or Crohn's disease during colorectal cancer screening (2010-2021), medication use was compared with symptomatic patients and healthy non-IBD controls. Asymptomatic patients showed a higher use of cardiovascular, antiparasitic, musculoskeletal, respiratory, and sensory organ medications up to 5 years before diagnosis.

Acanthoside B attenuates NLRP3-mediated pyroptosis and ulcerative colitis through inhibition of tAGE/RAGE pathway.

Acanthoside B (Aca.B), a principal bioactive compound extracted from , exhibits superior anti-inflammatory capacity. Ulcerative colitis is a nonspecific inflammatory bowel disease with unknown etiology.

Microsporidiosis in Patients with Autoimmune Diseases Undergoing Monoclonal Antibody Associated Therapy.

We present Enterocytozoon bieneusi infection in four patients with autoimmune diseases undergoing prolonged monoclonal antibody therapies. Two patients suffered from inflammatory bowel disease and received anti-TNF therapies, whereas two other patients suffered from systemic lupus erythematosus with renal involvement and received anti-CD20 or anti-BLyS protein therapies. Three out of four patients consulted for diarrhea with abdominal pain without intestinal inflammation or bleeding at the time of sampling.

The Effect of the Size of Gold Nanoparticle Contrast Agents on CT Imaging of the Gastrointestinal Tract and Inflammatory Bowel Disease.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD). CT imaging with contrast agents is commonly used for visualizing the gastrointestinal (GI) tract in UC patients. Contrast agents that provide enhanced imaging performance are highly valuable in this field.

Inflammatory bowel disease vs strongyloidiasis.

We report the case of a 38-year-old woman with a 10-year history of ulcerative proctosigmoiditis. Two months after traveling to Morocco, she developed gastrointestinal symptoms accompanied by eosinophilia in blood tests. Four months later, she progressed to systemic illness with pulmonary involvement.
