BACKGROUND & AIMS: Understanding the interactions between brain and gastrointestinal disorders requires analysis of the order of disease onset. We analyzed data from 2 independent studies to determine the proportion of individuals with diagnoses of functional gastrointestinal disorders (FGIDs) before diagnoses of mood or anxiety disorders (gut to brain), and vice versa (brain to gut). METHODS: We collected data from a retrospective study of 4966 patients diagnosed with a FGID (irritable bowel syndrome, dyspepsia, or constipation) and mood or anxiety disorder at general practices in the United Kingdom (health care seekers) over an average period of 13...

The Mechanism of Action of the Human Microbiome (MAHMI) database is a unique resource that provides comprehensive information about the sequence of potential immunomodulatory and antiproliferative peptides encrypted in the proteins produced by the human gut microbiota. Currently, MAHMI database contains over 300 hundred million peptide entries, with detailed information about peptide sequence, sources and potential bioactivity. The reference peptide data section is curated manually by domain experts. The in silico peptide data section is populated automatically through the systematic processing of publicly available exoproteomes of the human microbiome...

Gastrointestinal disorders are common complications of diabetes mellitus and include gastroparesis, nonalcoholic fatty liver disease, gastroesophageal reflux disease, and chronic diarrhea. Symptoms of gastroparesis include early satiety, postprandial fullness, nausea, vomiting of undigested food, bloating, and abdominal pain. Gastroparesis is diagnosed based on clinical symptoms and a delay in gastric emptying in the absence of mechanical obstruction. Gastric emptying scintigraphy is the preferred diagnostic test...

BACKGROUND: This review supersedes the original Cochrane review first published in 2008 (Huertas-Ceballos 2008).Between 4% and 25% of school-aged children complain of recurrent abdominal pain (RAP) severe enough to interfere with their daily activities. No organic cause for this pain can be found on physical examination or investigation for the majority of such children. Although many children are managed by reassurance and simple measures, a large range of psychosocial interventions involving cognitive and behavioural components have been recommended...

Products derived from the manufacturing or processing of plant based foods: cereals, fruits, vegetables, as well as algae, are sources of abundant dietary fibre. Diets high in dietary fibre have been associated with the reduced risk of cardiovascular disease, diabetes, hypertension, obesity, and gastrointestinal disorders. These fibre-rich products and byproducts can also fortify foods, increase their dietary fibre content and result in healthy products, low in calories, cholesterol and fat. Traditionally, consumers have chosen foods such as whole grains, fruits and vegetables as sources of dietary fibre...

The development of the human infant intestinal microbiota is a sequential process that begins in utero and continues during the first 2 to 3 years of life. Microbial composition and diversity are shaped by host genetics and multiple environmental factors, of which diet is a principal contributor. An understanding of this process is of clinical importance as the microbiota acquired in early life influence gastrointestinal, immune and neural development, and reduced microbial diversity or dysbiosis during infancy is associated with disorders in infancy and later childhood...

Physical health has a direct relationship with digestive function. Any abnormalities in the link may cause malnutrition, endocrine disorders, and the decline of organ functions. Obestatin, a biologically active peptide, is encoded by the ghrelin gene. Most studies suggest that obestatin is a pleiotropic peptide, which acts by suppressing the motility of the gastrointestinal tract, regulating the secretion of insulin, reducing inflammation and apoptosis, and promoting proliferation. These characteristics suggest that obestatin may represent an efficient way to prevent the occurrence and development of some digestive diseases...

Our emotional state can have many consequences on our somatic health and well-being. Negative emotions such as anxiety play a major role in gut functioning due to the bidirectional communications between gut and brain, namely, the brain-gut axis. The irritable bowel syndrome (IBS), characterized by an unusual visceral hypersensitivity, is the most common disorder encountered by gastroenterologists. Among the main symptoms, the presence of current or recurrent abdominal pain or discomfort associated with bloating and altered bowel habits characterizes this syndrome that could strongly alter the quality of life...

Stress is often marked by a state of hyperarousal to aid the initiation of necessary stress response for the successful management of stressful stimuli. It can be manifested as a challenge (stimulus) that requires behavioral, psychological, and physiological adaptations for the maintenance of a state of homeostasis in response to stressful stimuli. In an organism, miscellaneous stressors trigger a wide spectrum of alterations in hormonal and neuronal physiologies, resulting in behavioral (anxiety and depression disorders, diminished food intake and gastrointestinal dysfunctions, decline in sexual behavior, diabetes, and loss of cognitive function) and other physiological responses...

Functional bowel disorders (FBDs) are functional gastrointestinal disorders with symptoms attributable to the middle or lower gastrointestinal tract. These include irritable bowel syndrome, functional bloating, functional constipation, functional diarrhea, and unspecified FBD. Increasing evidence has emerged of late that intestinal microbiota is involved in the pathogenesis of FBDs. In this review, the therapeutic benefits and future perspectives of the currently available strategies for modifying the gut microbiota in FBDs are described, focusing primarily on irritable bowel syndrome and functional constipation...

BACKGROUND/OBJECTIVE: Outcomes of treatment for multidrug-resistant tuberculosis (MDR-TB) remain poor worldwide. Among patients with MDR-TB in Belarus who started treatment in 2012, only 54% completed it successfully, with treatment failure reported in 22% of the patients; additionally, 11% died and 13% were lost to follow-up or remained unevaluated. In Belarus, to improve outcomes, bedaquiline was introduced in MDR-TB treatment in June 2015. The national TB program developed measures to monitor safety and effectiveness of bedaquiline-containing regimens in line with the World Health Organization recommendations...

The enteric nervous system (ENS) is a network of neurons and glia that controls ongoing gastrointestinal (GI) functions. Damage or injury to the ENS can lead to functional GI disorders. Current data support the conclusion that many functional GI disorders are caused by an imbalance between gut microbes and the immune system but how the ENS is involved in these interactions is less understood. Due to the proximity of the ENS to bacteria and other foreign antigens present in the GI tract, it is important to prevent the passage of these antigens through the GI epithelium...

The regulation of physiological gut functions such as peristalsis or secretion of digestive enzymes by the central nervous system via the Nervus vagus is well known. Recent investigations highlight that pathological conditions of neurological or psychiatric disorders might directly interfere with the autonomous neuronal network of the gut - the enteric nervous system, or even derive from there. By using a murine Alzheimer's disease model, we investigated a potential influence of disease-associated changes on gastrointestinal properties...

Ghrelin and motilin are released from gastrointestinal endocrine cells during hunger, to act through G protein-coupled receptors that have closely related amino acid sequences. The actions of ghrelin are more complex than motilin because ghrelin also exists outside the GI tract, it is processed to des-acyl ghrelin which has activity, ghrelin can exist in truncated forms and retain activity, the ghrelin receptor can have constitutive activity and is subject to biased agonism and finally additional ghrelin-like and des-acyl ghrelin receptors are proposed...

Melatonin synchronizes central but also peripheral oscillators (fetal adrenal gland, pancreas, liver, kidney, heart, lung, fat, gut, etc.), allowing temporal organization of biological functions through circadian rhythms in relation to periodic environmental changes and therefore adaptation of the individual to his/her internal and external environment. Measures of melatonin are considered the best peripheral indices of human circadian timing. First, the pharmacology of melatonin (biosynthesis and circadian rhythms, pharmacokinetics and mechanisms of action) is described, allowing a better understanding of the short and long term effects of melatonin following its immediate or prolonged release...

Children with autism are commonly affected by gastrointestinal problems such as abdominal pain, constipation and diarrhea. In recent years, there has been a growing interest in the use of probiotics in this population, as it hypothetically may help to improve bowel habits and the behavioral and social functioning of these individuals. The gut microbiome plays an important role in the pathophysiology of organic as well as functional gastrointestinal disorders. Microbial modification with the use of antibiotics, probiotics, and fecal transplantation have been effective in the treatment of conditions such as recurrent Clostridium difficile infection, pouchitis, and irritable bowel syndrome...
