Endoscopic suspect of subacute occlusive mesenteric ischemia.

A 74-year-old patient presented to our emergency department with melena for 24 hours, associated with postprandial abdominal pain, predominantly in the epigastrium, for one month. Urgent gastroscopy showed a pale mucosa with loss of vascular pattern in the gastric antrum, as well as several superficial ulcers, Forrest III, at that level and in the duodenal bulb highly suggestive of ischaemia. An abdominal computed tomography angiography (CTA) revealed a filiform celiac trunk, with calcified atherosclerotic plaques in the ostium, superior mesenteric artery and both renal arteries, with absence of enhancement in a large part of the intestinal wall, suggestive of ischaemia.

Irritable bowel syndrome.

Irritable bowel syndrome is one of the most common functional bowel disorders, and has a substantial impact on patients' daily lives, as well as a big economic impact on society. It is characterised by abdominal pain, bloating and abdominal distention and altered bowel movements, with a predominance of diarrhoea, constipation, or alternation of these signs, which cannot be explained by a structural or biochemical abnormality. Its aetiopathogenesis and pathophysiological mechanism are unknown.

Influence of Compliance to Diet and Self-Efficacy Expectation on Quality of Life in Patients with Celiac Disease in Spain.

The purpose of this study is to understand the health-related quality of life (HRQoL) in patients with celiac disease (CD) and analyze its main determinants. A transversal descriptive study of 738 patients with celiac disease was carried out. A series of questionnaires were answered related to their HRQoL, adherence to a gluten-free diet (GFD), and self-efficacy beliefs among other relevant variables.

Involvement of the digestive system in covid-19. A review.

The SARS-CoV-2 pandemic is leading to high mortality and a global health crisis. The primary involvement is respiratory; however, the virus can also affect other organs, such as the gastrointestinal tract and liver. The most common symptoms are anorexia and diarrhea.

The effect of self-efficacy expectations in the adherence to a gluten free diet in celiac disease.

To analyse the effect of general and specific self-efficacy on the adherence to a gluten free diet (GFD) in patients with celiac disease along with the effect of other relevant variables. 271 patients with celiac disease participated in this transversal descriptive study and completed a series of questionnaires regarding adherence (CDAT), general self-efficacy (GSES) and specific self-efficacy (Celiac-SE) and quality of life (CD-Qol), among others. Dependent variable was adherence to the Gluten Free Diet (GFD).

Prevalence of celiac disease in primary care: the need for its own code.

Background: Celiac disease (CD) is an autoimmune chronic enteropathy of the small intestine caused by exposure to gluten in genetically predisposed individuals. CD is not easy to diagnose due to its unspecific symptomatology, especially in adults, a diagnosed/undiagnosed ratio of 1:7 is estimated. CD does not have its own code in the International Classification of Primary Care (ICPC) but it is coded under code D99 "Disease digestive system, other", which hinders diagnosis, intervention and research.

Development and Validation of a Specific Self-Efficacy Scale in Adherence to a Gluten-Free Diet.

The aim of this study was to develop a scale to assess the levels of specific self-efficacy in order to enhance adherence to a gluten-free diet and the life quality of celiac patients. Celiac disease is a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed people. The only treatment is a strict lifelong gluten-free diet.

From the intestinal flora to the microbiome.

In this article, the history of the microbiota is reviewed and the related concepts of the microbiota, microbiome, metagenome, pathobiont, dysbiosis, holobiont, phylotype and enterotype are defined. The most precise and current knowledge about the microbiota is presented and the metabolic, nutritional and immunomodulatory functions are reviewed. Some gastrointestinal diseases whose pathogenesis is associated with the intestinal microbiota, including inflammatory bowel disease, irritable bowel syndrome and celiac disease, among others, are briefly discussed.

New psychological therapies for irritable bowel syndrome: mindfulness, acceptance and commitment therapy (ACT).

The current goal of treatment in irritable bowel syndrome (IBS) focuses primarily on symptom management and attempts to improve quality of life. Several treatments are at the disposal of physicians; lifestyle and dietary management, pharmacological treatments and psychological interventions are the most used and recommended. Psychological treatments have been proposed as viable alternatives or compliments to existing care models.

Enough discussions about who should use propofol in gastrointestinal endoscopy.

Reflections in order to agree on who should be responsible for the deep sedation with propofol in gastrointestinal endoscopies, after so many squabble between anaesthesiologists and endoscopists.

Combined endoscopic resolution of iatrogenic stricture in an ureterosigmoidostomy.

Ureteroenterostomy allows the replacement of the bladder role after radical cystectomy. Anastomotic stricture is a relatively common complication that may require surgical repair. We report a case of iatrogenic stricture in a Mainz-II ureterosigmoidostomy that was satisfactorily resolved using a combined endoscopic-urological approach.

Review of the role of probiotics in gastrointestinal diseases in adults.

Background: Probiotics may act as biological agents that modify the intestinal microbiota and certain cytokine profiles, which can lead to an improvement in certain gastrointestinal diseases.

Objectives: To conduct a review of the evidence of the role of probiotics in certain gastrointestinal diseases in adults.

Search Methods: Review conducted using appropriate descriptors, filters and limits in the PubMed database (MEDLINE).
