The Abdominal Ultrasonography Results of Cappadocia Cohort Study of Turkey Reveals High Prevalence of Fatty Liver.

Background: There is limited data about the prevalence of frequent gastrointestinal diseases in developing parts of the world based on community-based screening studies. Therefore, we aimed to present the detailed transabdominal ultrasonography results of the previously completed Turkey Cappadocia cohort study, which included a population-based evaluation of gastrointestinal symptoms and diseases in adults.

Methods: This cross-sectional study was conducted in Cappadocia cohort.

The Effect of Vedolizumab on Spondyloarthritis Symptoms in a Cohort of Inflammatory Bowel Disease Patients.

Objective: Vedolizumab is a novel anti-inflammatory molecule that is currently being used in the treatment of refractory inflammatory bowel disease. The mode of action is inhibiting the binding of activated T lymphocytes to the adhesion molecule 1 of intestinal mucosal cells. Due to its local effect, systemic immunosuppression is not expected, and this may have a negative effect on the extra-intestinal symptoms of inflammatory bowel disease, particularly spondyloarthritis.

Inflammatory bowel diseases (IBD) affect millions of people worldwide with increasing incidence. Ulcerative colitis (UC) and Crohn's disease (CD) are the two most common IBDs. There is no definite cure for IBD, and response to treatment greatly vary among patients.

Functional bowel disorders with diarrhoea: Clinical guidelines of the United European Gastroenterology and European Society for Neurogastroenterology and Motility.

Irritable bowel syndrome with diarrhoea (IBS-D) and functional diarrhoea (FDr) are the two major functional bowel disorders characterized by diarrhoea. In spite of their high prevalence, IBS-D and FDr are associated with major uncertainties, especially regarding their optimal diagnostic work-up and management. A Delphi consensus was performed with experts from 10 European countries who conducted a literature summary and voting process on 31 statements.

In recent years, there is a growing number of studies that show a 4-8 wk low fermentable oligo, di- and mono-saccharides and polyols (FODMAP) diet has a 50%-80% significant effect on symptoms in IBS patients. There is strong evidence suggesting that changes in fecal microbiota have an impact on IBS pathogenesis.

Prevalence of irritable bowel syndrome-like symptoms using Rome IV criteria in patients with inactive inflammatory bowel disease and relation with quality of life.

Irritable bowel syndrome (IBS)-like symptoms tend to be common in inflammatory bowel disease (IBD) patients even during the long-standing remission phase, and quality of life (QOL) seem to reduce in IBD patients with such symptoms. Thus, the aim of this study was to define the prevalence of IBS-like symptoms in inactive IBD patients using Rome IV criteria and evaluate the effect of IBS-like symptoms on QOL.Total 137 patients with IBD (56 with ulcerative colitis (UC) and 81 with Crohn disease (CD), who had been in long-standing remission according to the clinical scoring system and 123 control participants were included.

Iron deficiency (ID) and iron deficiency anemia (IDA) are important signs of gastrointestinal (GI) hemorrhage. Therefore, the evaluation of the GI tract should be a part of the diagnostic protocol in patients with IDA. GI hemorrhage is not a disease but a symptom, which might have different underlying causes.
