Background and Aim: Variceal bleeding is the second most important precipitating factor related to the development of episodic hepatic encephalopathy; but to date there are no recommendations to prevent this complication. The aim of this study was to compare if primary prophylaxis with lactulose or L-ornithine L-aspartate or rifaximin, in cirrhotic patients with variceal bleeding, is better than placebo for avoiding the development of hepatic encephalopathy. Methods: A randomized, double-blind, placebo-controlled clinical trial (ClinicalTrials...

Attention-deficit/hyperactivity disorder (ADHD) is a neurologic disorder characterized by hyperactivity/impulsivity and/or inattentiveness, with genetic and environmental factors contributing to the disorder. With the growing recognition of the microbiome's role in many neurological disorders, the authors propose that it may also be implicated in ADHD. Here, we describe several evolving areas of research to support this hypothesis. First, a unique composition of gut bacteria has been identified and linked to behaviors in ADHD...

BACKGROUND: The insufflation of gas during colonoscopy leads to distention of the colon with abdominal discomfort and pain for the patients. Use of CO2 during endoscopy is reported to minimize abdominal discomfort during and after endoscopy. Aim of this study was to find out whether this improvement leads to decreased dosage of sedation drugs in order to improve patient's safety and satisfaction. METHODS: In this double-blind, randomized and controlled study 150 Patients referred to colonoscopy were assigned to either CO2 or air insufflation...

Pulses are an excellent source of protein and dietary fiber and are consumed around the world. Their consumption has been recommended as part of a healthy diet. However, they contain various antinutrients such as tannins and trypsin inhibitors, as well as indigestible carbohydrates called alpha-galactosides. These oligosaccharides are fermented by the microorganisms in the gut, producing gas and causing flatulence in healthy individuals. While this flatulence is undesirable (and results in their low acceptance in the Western diet), alpha-galactosides have also been hypothesized to increase susceptibility to bowel diseases, and their presence in the gut worsens the symptoms of patients with irritable bowel syndrome...

Prebiotics and diets low in fermentable oligo-, di-, mono-saccharides and polyols (low-FODMAP diet) might reduce symptoms in patients with functional gastrointestinal disorders, despite reports that some nonabsorbable, fermentable meal products (prebiotics) provide substrates for colonic bacteria and thereby increase gas production. We performed a randomized, parallel, double-blind study of patients with functional gastrointestinal disorders with flatulence. We compared the effects of a prebiotic supplement (2...

The purpose of the present study was to investigate the prevalence of gastrointestinal symptoms (GIS) amongst recreational runners during a marathon race, and potential nutritional factors that may contribute. Recreational runners of the 2017 Liverpool ( n = 66) and Dublin ( n = 30) marathons were recruited. GIS were reported post-marathon and we considered GIS in the 7 days prior to the marathon and during the marathon using the Gastrointestinal Symptom Rating Scale (GSRS). Nutritional intake was recorded using food diaries for the day before the race, morning of the race, and during the race; 43% of participants reported moderate (≥4) GIS in the 7 days prior to the marathon and 27% reported moderate symptoms during the marathon with most common symptoms being flatulence (16%) during training, and nausea (8%) during the marathon race...
