Peripartum Mental Illness in Mothers With Multiple Sclerosis and Other Chronic Diseases in Ontario, Canada.

Background And Objectives: Peripartum mood and anxiety disorders constitute the most frequent form of maternal morbidity in the general population, but little is known about peripartum mental illness in mothers with multiple sclerosis (MS). We compared the incidence and prevalence of peripartum mental illness among mothers with MS, epilepsy, inflammatory bowel disease (IBD), and diabetes and women without these conditions.

Methods: Using linked population-based administrative health data from ON, Canada, we conducted a cohort study of mothers with MS, epilepsy, IBD, and diabetes and without these diseases (comparators) who had a live birth with index dates, defined as 1 year before conception, between 2002 and 2017.

PSC and colitis: A complex relationship.

Primary sclerosing cholangitis is one of the most challenging conditions in hepatology, and due to our limited understanding of its pathogenesis, no causal therapies are currently available. While it was long assumed that a minority of people with IBD also develop PSC, which is sometimes labeled an extraintestinal manifestation of IBD, the clinical phenotype, genetic and intestinal microbiota associations strongly argue for PSC-IBD being a distinct form of IBD, existing alongside ulcerative colitis and Crohn's disease. In fact, the liver itself could contribute to intestinal pathology, clinically overt in 60 - 80 % of patients.

Computed tomography enterography-based radiomics for assessing mucosal healing in patients with small bowel Crohn's disease.

Background: Mucosal healing (MH) is the major therapeutic target for Crohn's disease (CD). As the most commonly involved intestinal segment, small bowel (SB) assessment is crucial for CD patients. Yet, it poses a significant challenge due to its limited accessibility through conventional endoscopic methods.

Tertiary lymphoid structures in colorectal cancer - organization and immune cell interactions.

Tertiary lymphoid structures (TLS), formerly recognized as Crohn's-like structures, serve as crucial biomarkers for evaluating the progression of colorectal cancer (CRC). Understanding their spatial distribution, cellular composition, and interactions within CRC is paramount for comprehending the immune response in the tumor microenvironment (TME). TLS are comprised of a T-cellular compartment and a B-cellular compartment, the latter encompassing follicular dendritic cells (FDCs), high endothelial venules (HEVs), and lymphatic vessels.

Development of a Second-Generation, Chemical Probe for PIKfyve.

We optimized our highly potent and cell-active chemical probe for phosphatidylinositol-3-phosphate 5-kinase (PIKfyve), SGC-PIKFYVE-1, resulting in compounds with improved potency and demonstrated stability. Use of an in-cell, kinome-wide selectivity panel allowed for confirmation of excellent in-cell selectivity of our lead compound, , and another promising analogue, . Evaluation of the pharmacokinetic (PK) profiles of these two compounds revealed that both are well tolerated systemically and orally bioavailable.

Understanding fatigue among Japanese patients with inflammatory bowel disease: insights from international comparisons and meta-analysis.

Background/aims: Fatigue is a common symptom in patients with inflammatory bowel disease (IBD). The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale has demonstrated reliability and validity in assessing fatigue in patients with IBD and is used worldwide. This study aimed to examine the current state of fatigue among Japanese patients with IBD using the FACIT-F scale and to compare these findings with data from global studies through a systematic review.

The SERPINB4 gene mutation identified in twin patients with Crohn's disease impaires the intestinal epithelial cell functions.

Crohn's disease (CD) is a chronic inflammatory autoimmune disease of unknown etiology. To identify new targets related to the initiation of CD, we screened a pair of twins with CD, which is a rare phenomenon in the Chinese population, for genetic susceptibility factors. Whole-exome sequencing (WES) of these patients revealed a mutation in their SERPINB4 gene.

Neutrophil-to-lymphocyte ratio at diagnosis predicts colonoscopic activity in pediatric inflammatory bowel diseases (pIBD).

Background: Neutrophil-to-lymphocyte ratio (NLR) is a novel biomarker studied in several autoimmune diseases including inflammatory bowel diseases (IBD) in adults, but poorly characterized in pediatric IBD (pIBD). We aimed to primarily investigate the relationship between NLR and pIBD endoscopic disease severity. We also examined whether NLR predicted hospitalization, surgery, and therapy response by 52 weeks.

Food access and the severity of newly diagnosed pediatric inflammatory bowel disease.

Objectives: Inflammatory bowel disease (IBD) results from genetic susceptibility, gut microbiome, and environmental factors. Diet, one modifiable environmental factor, has been linked to the increased prevalence of IBD. This study aimed to evaluate a potential association between food deserts and disease severity at diagnosis.

Safety and Efficacy of Ferric Carboxymaltose for Iron Deficiency Anemia in Inflammatory Bowel Disease: A Systematic Review.

Ulcerative colitis and Crohn's disease, two types of inflammatory bowel disease (IBD), often cause anemia, primarily due to iron deficiency and chronic inflammation. Anemia negatively affects patients' daily functioning and quality of life, causing symptoms including headaches, exhaustion, and dyspnea. In IBD, iron deficiency arises from reduced intake, chronic blood loss, and impaired absorption.

Understanding Predictors of Crohn's Disease: Determinants of Altered Barrier Function in Pre-Disease Phase of Crohn's Disease.

The pathogenesis of Crohn's disease (CD) remains unknown. The current working theory is that genetic susceptibility influences host-microbe interactions, resulting in chronic inflammation. Case-control studies fail to explain the triggers or pathogenesis of the disease, notably due to confounding factors in patients with established disease.

Real-World Impact of Uncontrolled Symptoms and Suboptimal Treatment Response in Patients With Crohn's Disease in the United States and Europe.

Background: Despite a wide range of available treatments, there is limited evidence as to why significant numbers of Crohn's disease (CD) patients do not achieve disease remission or continue to have residual symptom burden. We aimed to quantify the impact of this suboptimal treatment on patient symptom incidence and severity, quality of life (QoL), and work impairment.

Methods: Data were derived from the Adelphi Real World CD Disease Specific Programme, a cross-sectional survey of CD patients and their treating physicians in France, Germany, Italy, Spain, the United Kingdom, and the United States between January 2020 and March 2021.

Exit Interviews Exploring Patients' Experience of Change in Crohn's Disease Symptoms During the Mirikizumab Phase 3 Clinical Trial In Adult Patients With Moderately-to-Severely Crohn's Disease.

Background: Exit interviews with patients who completed the Phase 3 VIVID-1 mirikizumab clinical trial for moderately-to-severely active Crohn's disease explored the content validity of bowel urgency, stool frequency, and abdominal pain patient-reported outcome measures and perceptions of meaningful within-patient change and remission in these key Crohn's disease symptoms.

Methodology: Cognitive debriefing explored patient understanding of the bowel urgency numeric rating scale (Urgency NRS), Crohn's Disease Activity Index: Stool Frequency (CDAI-SF) and Abdominal Pain (CDAI-AP), and patient global rating/impression of severity/change (PGRS/PGIC). Perceptions of meaningful change and remission were explored qualitatively.

Dysplasia and Colorectal Cancer Surveillance in Ulcerative Colitis Patients in Latin America: Real-World Data.

Background: The prevalence of colorectal cancer (CRC) in patients with ulcerative colitis (UC) is higher than in the general population, in Latin America there is a progressive increase of UC, and information about CRC screening in inflammatory bowel disease (IBD) is scarce. The aim of this study was to analyze the findings of endoscopic surveillance of CRC in patients with IBD according to available technology.

Methods: Multicenter, cross-sectional, analytical study conducted in Latin American countries, in patients with UC, predominantly with more than 8 years of diagnosis and different degrees of disease activity.

Intravenous Steroids Do Not Improve Short-Term Outcomes of Patients With Crohn's Disease Presenting With an Acute Small Bowel Obstruction.

Background: Intravenous (IV) steroids are commonly used to treat acute flares of Crohn's disease (CD). However, it is unclear if they are beneficial in the setting of uncomplicated small bowel obstruction (SBO). We sought to examine if IV steroid administration improved short-term outcomes in patients with CD hospitalized for acute, uncomplicated SBO across three New York City hospital systems.

[Update on the pathophysiology, prediction and prevention of inflammatory bowel diseases].

Background: The pathophysiology of inflammatory bowel diseases is not fully understood. In a staged model by the European Crohn's and Colitis Organization (ECCO) regarding disease development, it is assumed that there is a population at risk for manifestation of disease following subtle changes over time.

Objective: This work aims to summarize the current state of knowledge regarding the pathophysiology, prediction and prevention of chronic inflammatory bowel diseases.

[Position statement of the Spanish Society of Primary Care Physicians (SEMERGEN) and Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) on the management of inflammatory bowel disease in Primary Care].

Primary Care is the first point of contact for most patients after the onset of symptoms of inflammatory bowel disease (IBD). Establishing an initial diagnostic process based on compatible symptoms and agreed criteria and referral pathways, depending on the degree of suspicion and the patient's situation, can reduce diagnostic delays. Once the patient is referred to the Digestive specialist and the diagnosis of IBD is established, a treatment and follow-up plan is structured.

A nested case-control study evaluating the relationship between adverse childhood experiences and immune-mediated inflammatory disease in the Canadian Longitudinal Study on Aging.

Objective: Adverse childhood experiences (ACE) have inconsistently been implicated as risk factors for immune-mediated inflammatory diseases (IMID). We evaluated whether the association of ACE with disease differs between IMID and other chronic diseases.

Design: Nested retrospective case-control study.

DepRescribing inapprOpriate Proton Pump InhibiTors (DROPIT): study protocol of a cluster-randomised controlled trial in Swiss primary care.

Objectives: Proton pump inhibitors (PPIs) are widely prescribed medications and commonly used for the treatment of gastric acid-related disorders. Nevertheless, PPIs are often overused leading to potential adverse effects and unnecessary healthcare costs. Deprescribing strategies have emerged to safely reduce or substitute inappropriate PPIs and optimise patient care in an evidence-based manner.
