Summary
Spanish inflammatory bowel disease (IBD) research shows sustained activity across clinical, translational, and basic science. While productivity varies regionally, international collaboration is extensive, though gender disparities in leadership persist.
Area of Science:
- Gastroenterology and Hepatology
- Immunology
- Biomedical Research
Background:
- Spanish Inflammatory Bowel Disease (IBD) research has grown significantly but lacks comprehensive evaluation of scientific output and international congress representation.
- This study assesses recent Spanish contributions to clinical, translational, and basic IBD research.
Purpose of the Study:
- To provide a descriptive overview of Spanish IBD research contributions.
- To analyze scientific leadership, regional distribution, methodologies, topics, and gender representation in IBD research.
Main Methods:
- Systematic retrieval and classification of 1,361 Spanish publications (2020-2024) from PubMed.
- Evaluation of 638 accepted communications at European Crohn's and Colitis Organisation congresses (2019-2024).
- Analysis included study type, research topic, methodology, journal quartile, authorship, presentation format, leadership, gender, and region.
Main Results:
- 61.3% of publications were clinical; 38.7% were basic/translational.
- 84.5% of publications were in Q1/Q2 journals; 30.6% of Q1 articles were in top-decile journals.
- Activity concentrated in Catalonia and Madrid; women showed higher leadership in basic/translational research.
Conclusions:
- Spanish IBD research demonstrates sustained activity and broad scope.
- Significant regional disparities in productivity and persistent gender disparities in leadership were observed.
- Extensive international collaboration characterizes the current landscape of Spanish IBD research.

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

01:30Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:20Inflammatory Bowel Disease IV: Clinical Manifestations
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
