#1
James F White
This article outlines the proposed 'syntrophic imbalance hypothesis' for etiology of bacterial endoparasitism diseases. This hypothesis involves microbes (archaea and bacteria) that exist in human body biofilms in syntrophic associations, where bacteria ferment nutrients to produce short chain fatty acids (SCFAs) that are used by methanogenic archaeons to produce methane. Overgrowth of archaea on human tissues (e.g., in association with intestines, teeth or lungs) results in excessive removal of SCFAs from the biofilms and this triggers bacteria in the free-living biofilm state to convert to the endoparasitic state and become intracellular in host cells where they incite inflammation and disease...

Historically, the epidemiology of gastrointestinal diseases in Asia was different from that in Western countries. Early studies suggested a low prevalence of irritable bowel syndrome (IBS) in Asia. As the diagnosis of IBS is symptom-based, and as symptom perception, expression and interpretation, are influenced by sociocultural perspectives including language, the presentation of IBS is expected to vary in different communities. Furthermore, the pathogenesis is multifactorial with psychosocial (stress, illness, behavior, diet) and biological (infection, gut microbiota, immune activation) variables interacting, and so we can anticipate that the development of IBS will vary in different environments...

Bile acids not only play a cardinal role in the digestion and absorption of fat and fat-soluble vitamins, but also significantly affect gastrointestinal motor, sensory and secretory functions, intestinal barrier permeability and the regulation of the inflammatory response. The results of recent studies have revealed complex interactions between bile acids and the gut microbiota. In addition, bile acids also play a role of signaling molecules regulating the activity of lipid and glucose metabolic pathways, as well as a role of ligands for transcription factors...

BACKGROUND AND PURPOSE: The majority of Parkinson's disease (PD) patients suffer from gastrointestinal symptoms of which constipation is considered the most prominent. Recently, in addition to constipation, a diagnosis of irritable bowel syndrome (IBS) was also found to be associated with increased PD risk. Gut microbiota alterations have been reported in IBS and recently also in PD. IBS-like bowel symptoms in PD and their possible connection to other non-motor symptoms and faecal microbiota were assessed...

Eamonn M M Quigley
PURPOSE OF REVIEW: The goal of this review is to review the current status of prokinetics and to place it in historical context. Impaired motility and thus propulsion have long been thought to play important roles in the pathogenesis of a number of gastrointestinal disorders including gastroesophageal reflux disease (GERD), gastroparesis, chronic idiopathic pseudo-obstruction, and constipation. Historically, disordered motility was also thought to contribute to a number of functional gastrointestinal disorders such as functional dyspepsia (FD) and irritable bowel syndrome (IBS)...

Psychological comorbidity is highly present in irritable bowel syndrome (IBS). Recent research points to a role of intestinal microbiota in visceral hypersensitivity, anxiety, and depression. Increased disease reactivity to psychological stress has been described too. A few clinical studies have attempted to identify features of dysbiosis in IBS. While animal studies revealed strong associations between stress and gut microbiota, studies in humans are rare. This review covers the most important studies on intestinal microbial correlates of psychological and clinical features in IBS, including stress, anxiety, and depression...

Exercise can have significant effects on gastrointestinal diseases. Regular, moderate exercise can impart beneficial effects for the intestinal microbiome, irritable bowel syndrome symptoms, and inflammatory bowel disease. High-intensity training or prolonged endurance training, on the other hand, can have negative effects on these same entities. Female athletes report a higher prevalence of irritable bowel syndrome and celiac disease, and furthermore, have gastrointestinal symptoms modulated by the menstrual cycle...

INTRODUCTION: Little is known about the impact of MST on chronic pain conditions among female Veterans. The primary objective of this study was to compare the prevalence of chronic pain conditions among U.S. female veterans with a history of military sexual trauma (MST) to those without a history of MST. We anticipated that female Veterans with a history of MST would have higher associations with chronic pain conditions than the female Veterans without a history of MST. MATERIALS AND METHODS: This was a large-scale, retrospective study using the Veterans' Health Administration Corporate Data Warehouse with institutional approval (15-H175)...

Postinfection irritable bowel syndrome (PI-IBS) is a diarrheal disease that develops after infectious gastroenteritis (IGE). Profound alterations in the microbiota accompany IGE yet only 10% of IGE patients progress to PI-IBS. This review explores research linking IGE severity, psychological comorbidity, PI-IBS, and the microbiome in various patient populations. Selective pressures caused by inflammation and increased gastrointestinal motility during gastroenteritis can alter intestinal bacterial phyla including Bacteroidetes, Firmicutes, and Proteobacteria...

Giardiasis is a treatable disease, caused by the flagellated protozoan parasite, Giardia duodenalis (G. duodenalis). It is one of the most common enteric parasites found globally to cause gastrointestinal disturbances, and infections may result in long-term irritable bowel syndrome-like symptoms. It is a common misconception that giardiasis is associated with foreign travel, which results in locally acquired cases in the UK being underdiagnosed. This report highlights the findings from one large Scottish Health Board, arising from a change in testing methodology, which resulted in the screening of all stools submitted for enteric investigations for G...

Faecal microbiota transplantation (FMT) is the transferral of faeces from a healthy donor to a patient with a disease linked to disturbances in the gut microbiota. The treatment has been implemented at several hospitals in Denmark, and banks with frozen donor stool material have been established. The effect of FMT for recurrent Clostridium difficile infection is well-documented. FMT cannot be recommended for routine clinical use for inflammatory bowel disease and irritable bowel syndrome because of lack of data from clinical trials...

Fibromyalgia appears to present in subgroups with regard to biological pain induction, with primarily inflammatory, neuropathic/neurodegenerative, sympathetic, oxidative, nitrosative, or muscular factors and/or central sensitization. Recent research has also discussed glial activation or interrupted dopaminergic neurotransmission, as well as increased skin mast cells and mitochondrial dysfunction. Therapy is difficult, and the treatment options used so far mostly just have the potential to address only one of these aspects...

Herbal combination preparations are widely used in traditional herbal medicine and are even established as modern evidence-based herbal medicinal products. The rationale behind such combinations is often questioned and assessing the contribution of each of the combination partners to overall activity is challenging. STW 5 (Iberogast) is such a combination with confirmed clinical efficacy in functional gastrointestinal disorders. It consists of nine plant extracts responsible for its multitarget function in these multifactorial diseases with their heterogeneous and overlapping pathomechanisms...

BACKGROUND: Objective measures of pain severity remain ill defined, although its accurate measurement is critical. Reciprocal baroreflex mechanisms of blood pressure (BP) control were found to impact differently on pain regulation, and thus their asymmetry was hypothesized to also connect to chronic pain duration and severity. METHODS: Seventy-eight female patients with irritable bowel syndrome (IBS) and 27 healthy women were assessed for IBS severity and chronicity, negative affect, and various measures of resting autonomic function including BP, heart rate and its variability (HRV), baroreceptor-sensitivity to activations and inhibitions, gains of brady- and tachy-cardiac baro-responses, gains of BP falls/rises, and BP start points for these spontaneous baroreflexes...
