OBJECTIVE: Constipation is a common symptom affecting up to 30% of the Western population and is strongly associated with the presence of intestinal methanogens, which may directly inhibit motor activity. Two recent studies performed on adult and children affected by chronic constipation showed that the supplementation with L. reuteri significantly improved bowel movements. Whether its action is related to a decreasing of methane (CH4) production has never been tested. We have therefore designed a study aimed at testing this hypothesis...

BACKGROUND: Constipation is a common symptom in patients with advanced disease taking opioids. Opioid-induced constipation (OIC) is commonly treated with laxatives and stool softeners. Recently, newer agents have come to market which broaden options for patients in whom first-line therapies are not effective. OBJECTIVE: To determine what pharmacologic regimens are currently used in hospice programs to prevent and treat OIC, whether those regimens have changed with the introduction of newer agents and evidence discouraging the use of docusate, and whether hospice programs are standardizing the management of OIC...

RATIONALE: Regorafenib represents a treatment option in heavily pretreated patients affected by metastatic colorectal cancer (mCRC). Its safety profile is typical of small-molecule tyrosine-kinase inhibitors (TKIs) and most adverse events are manageable. PATIENT CONCERNS: A 56 years-old Caucasian man affected by mCRC with normal hepatic reserve was treated with regorafenib as second-line treatment. After only 2 days of therapy, the patient presented to the emergency department due to impairment of both spatial and temporal orientation and motor function with bradylalia...

OBJECTIVES: The esophageal mucosal integrity is impaired in eosinophilic esophagitis (EoE) and it has been suggested that the duodenal permeability is increased. The absence of food allergens may restore the integrity. The aims of this study were to assess duodenal permeability in EoE and to evaluate the effect of an elemental diet on the esophageal and duodenal integrity. METHODS: In this prospective study 17 adult EoE patients and 8 healthy controls (HC) were included...

BACKGROUND: One of the most promising uses of whey permeate (WP) is the synthesis of prebiotic oligosaccharides. Herein, commercial WP was submitted to chemical isomerisation catalysed by sodium borate at an alkaline pH and subsequent purification using anion-exchange resins to remove boron. Afterwards, purified mixtures were used to synthesise prebiotic oligosaccharides using β-galactosidase from Bacillus circulans. RESULTS: Isomerisation of concentrated WP (200 g L(-1) lactose) gave rise to levels of lactulose up to 155...

BACKGROUND: Divalproex sodium/valproic acid (VPA) is an antiepileptic drug approved for use in epilepsy and bipolar disorder. Valproate-induced hyperammonemia occurs in up to 50% of VPA-treated patients, some of whom may become encephalopathic. Valproate-induced hyperammonemic encephalopathy (VHE) is thought to be rare, and for a variety of reasons, the diagnosis requires a high index of suspicion. OBJECTIVE: The study's goals are to determine how common VHE is, and the quality of treatment provided when diagnosed...

BACKGROUND AND AIMS: The barrier function of the small intestinal mucosa prevents the introduction of undesired pathogens into the body. Breakdown of this barrier function increases intestinal permeability. This has been proposed to induce not only gastrointestinal diseases, including inflammatory bowel disease and irritable bowel syndrome, but also various other diseases, including allergies, diabetes mellitus, liver diseases, and collagen diseases, which are associated with this so called "leaky gut syndrome...

Increased intestinal permeability has been implicated in various pathologies, has various causes, and can develop during vigorous athletic training. Colostrum bovinum is a natural supplement with a wide range of supposed positive health effects, including reduction of intestine permeability. We assessed influence of colostrum supplementation on intestinal permeability related parameters in a group of 16 athletes during peak training for competition. This double-blind placebo-controlled study compared supplementation for 20 days with 500 mg of colostrum bovinum or placebo (whey)...

BACKGROUND: Environmental enteropathy (EE), the adverse impact of frequent and numerous enteric infections on the gut resulting in a state of persistent immune activation and altered permeability, has been proposed as a key determinant of growth failure in children in low- and middle-income populations. A theory-driven systems model to critically evaluate pathways through which enteropathogens, gut permeability, and intestinal and systemic inflammation affect child growth was conducted within the framework of the Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) birth cohort study that included children from eight countries...

Hepatic encephalopathy (HE) is a complex disease requiring a multidisciplinary approach among specialists, primary care team, family, and caregivers. HE is currently a diagnosis of exclusion, requiring an extensive workup to exclude other possible etiologies, including mental status changes, metabolic, infectious, traumatic, and iatrogenic causes. The categorization of HE encompasses a continuum, varying from the clinically silent minimal HE (MHE), which is only detectable using psychometric tests, to overt HE, which is further divided into four grades of severity...

In this study the repressor of Escherichia coli lac operon, LacI, has been engineered for altered effector specificity. A LacI saturation mutagenesis library was subjected to Fluorescence Activated Cell Sorting (FACS) dual screening. Mutant LacI-L5 was selected and it is specifically induced by lactulose but not by other disaccharides tested (lactose, epilactose, maltose, sucrose, cellobiose and melibiose). LacI-L5 has been successfully used to construct a whole-cell lactulose biosensor which was then applied in directed evolution of cellobiose 2-epimerase (C2E) for elevated lactulose production...

The main symptoms of irritable bowel syndrome (IBS) include abnormal frequency of bowel movements. On this basis, three main clinical types of the disease have been distinguished, i.e.: constipation (IBSC), diarrhea (IBS-D) and mixed-type (IBS-M) in accordance with the Rome III criteria. These disorders mainly affect the colon, but symptoms related to upper gastrointestinal tract are also often observed. AIM: The aim of the study was to assess the oro-caecal transit time in patients with irritable bowel syndrome with IgG-dependent hypersensitivity to cereal products...
