Processed Food as a Risk Factor for the Development and Perpetuation of Crohn's Disease-The ENIGMA Study.

(1) Background: Developing countries have experienced a rapid recent rise in Inflammatory Bowel Disease (IBD) incidence and emerging evidence suggests processed foods and food additives may predispose one to the development and perpetuation of Crohn's disease (CD). The aim of this study was to evaluate processed food and food additive intake in CD patients and controls, in Australia (high CD incidence), Hong Kong (intermediate incidence) and mainland China (emerging incidence). (2) Methods: In 274 CD patients (CD), 82 first-degree relatives (FDR), 83 household members (HM) and 92 healthy unrelated controls (HC) from Australia (n = 180), Hong Kong (HK) (n = 160) and mainland China (n = 191) we estimated early life (0-18 years), recent (12 months), and current processed and food additive intake, using validated questionnaires and a 3-day-food diary.

Childhood antibiotics as a risk factor for Crohn's disease: The ENIGMA International Cohort Study.

Background And Aim: Environmental factors play a key role in development of Crohn's disease (CD), thought to be mediated by changes in the gut microbiota. We aimed to delineate the potential contribution of antibiotic exposure to subsequent development of CD, across diverse geographical populations.

Methods: This case-control study in Australia and three cities in China (Hong Kong, Guangzhou, and Kunming) included four groups: patients with CD, at-risk individuals including non-affected first-degree relatives (FDRs) and household members of CD patients (HM), and unrelated healthy controls (HCs).

Pelvic floor behavioral treatment for fecal incontinence and constipation in quiescent inflammatory bowel disease.

Background And Aim: Refractory bowel symptoms in quiescent inflammatory bowel disease (IBD) are common but evidence for effective management is limited. We aimed to determine whether behavioral treatment, including pelvic floor muscle training, decreases the severity of functional bowel symptoms in patients with quiescent IBD. Secondary aims were to evaluate the treatment effect on quality of life, psychological well-being and pelvic floor muscle function.

Long-Term Outcome of Multidisciplinary Versus Standard Gastroenterologist Care for Functional Gastrointestinal Disorders: A Randomized Trial.

Background & Aims: Functional gastrointestinal disorders are common and costly to the healthcare system. In the Multidisciplinary Treatment of Functional Gastrointestinal Disorders study, we demonstrated that multidisciplinary care resulted in superior clinical and cost outcomes, when compared with standard gastroenterologist-only care at end of treatment. In this study we evaluate the longer-term outcomes.

Diet and gut microbiome in gastrointestinal disease.

The composition and function of the dynamic microbial community that constitutes the gut microbiome is continuously shaped by the host genome, mode of birth delivery, geography, life stage, antibiotic consumption, and diet. Diet is one of the most potent factors in determining microbiome integrity. Dietary factors in early life appear to substantially determine the risk of later health or disease; for example, exposure to ultra-processed foods in childhood or adolescence may increase the risk of the later development of inflammatory bowel disease or colorectal cancer, thought to be mediated by modulation of the gut microbiota.

Interventions to Improve Adherence to Preventive Care in Inflammatory Bowel Disease: A Systematic Review.

Background: Preventive health measures reduce treatment and disease-related complications including infections, osteoporosis, and malignancies in patients with inflammatory bowel disease (IBD). Although guidelines and quality measures for IBD care highlight the importance of preventive care, their uptake remains variable. This systematic review evaluates interventions aimed at improving the rates of provision and uptake of preventive health measures, including vaccinations, bone density assessment, skin cancer screening, cervical cancer screening, and smoking cessation counseling.

Determinants of long-term function and general well-being in patients with an ileoanal pouch.

Background And Aim: Fecal incontinence and/or evacuation difficulty are common after ileoanal pouch surgery. This study aimed to determine whether the development of these symptoms can be predicted so that preventive measures might be instituted.

Methods: A consecutive series of 46 patients with ulcerative colitis (median age at surgery, 41 years; 50% female) and a functioning pouch for a duration ≥12 months was included.

Elucidation of Proteus mirabilis as a Key Bacterium in Crohn's Disease Inflammation.

Background & Aims: Proteus spp, Gram-negative facultative anaerobic bacilli, have recently been associated with Crohn's disease (CD) recurrence after intestinal resection. We investigated the genomic and functional role of Proteus as a gut pathogen in CD.

Methods: Proteus spp abundance was assessed by ure gene-specific polymerase chain in 54 pairs of fecal samples and 101 intestinal biopsies from patients with CD and healthy controls.

Standard gastroenterologist versus multidisciplinary treatment for functional gastrointestinal disorders (MANTRA): an open-label, single-centre, randomised controlled trial.

Background: Functional gastrointestinal disorders are common and costly to the health-care system. Most specialist care is provided by a gastroenterologist, but only a minority of patients have improvement in symptoms. Although they have proven to be effective, psychological, behavioural, and dietary therapies are not provided routinely.

Development and Validation of Surveys to Estimate Food Additive Intake.

(1) Background: The Food Agricultural Organization/World Health Organization (FAO/WHO) International Food Standards (hereafter, CODEX) declares additives non-toxic, but they have been associated with changes to the microbiota changes and thinning of the mucus layer of the gut. Their widespread use has occurred in parallel with increased inflammatory bowel disease (IBD) incidence. This paper reports on the development and validation of surveys to estimate additive intake.

Defining Optimal Care for Functional Gut Disorders - Multi-Disciplinary Versus Standard Care: A Randomized Controlled Trial Protocol.

Background: Functional gastrointestinal disorders (FGIDs) are the commonest reason for gastroenterological consultation, with patients usually seen by a specialist working in isolation. There is a wealth of evidence testifying to the benefit provided by dieticians, behavioral therapists, hypnotherapists and psychotherapists in treating these conditions, yet they rarely form a part of the therapeutic team, and these treatment modalities are rarely offered as part of the therapeutic management. There has been little examination of different models of care for FGIDs.

Delivery of care for functional gastrointestinal disorders: A systematic review.

Background: A diverse range of treatments are available for the treatment of functional gastrointestinal disorders (FGIDs). Individual treatments, including drug therapies, behavioral therapy ("biofeedback"), psychological therapies, and dietary therapies, have been well validated in controlled, randomized trials and real-life case series. However, few studies have evaluated models of delivery of care for the whole population of referred patients with an FGID.

Outcome of hospital outpatient treatment of functional gastrointestinal disorders.

Background: Functional gastrointestinal disorders (FGID) are the commonest conditions observed in gastrointestinal (GI) practice, yet the outcomes of their outpatient care are not known.

Aim: To evaluate the outcome for patients with FGID attending a specialist GI clinic.

Methods: Consecutive, newly referred patients with a FGID attending a specialist GI clinic in a tertiary hospital, over a 1-year period were reviewed and then completed a phone survey to assess current symptoms.

Diabetes and poor glycaemic control in rural patients with coronary artery disease.

Background: The burden of cardiovascular disease is higher in rural populations. Existing data on rural cardiovascular health is mainly based on community surveys. Regional differences are not well addressed.

The resting status of the coronary microcirculation is a predictor of microcirculatory function following elective PCI for stable angina.

Background/objectives: We performed a prospective study to investigate markers of percutaneous coronary intervention (PCI) related microvascular injury.

Methods: Consecutive patients undergoing PCI for stable angina were studied. The index of microvascular resistance (IMR) was measured using a temperature and pressure sensing guidewire (TPSG) before and after single vessel PCI.

Evolutionary ancestry and novel functions of the mammalian glucose transporter (GLUT) family.

Background: In general, sugar porters function by proton-coupled symport or facilitative transport modes. Symporters, coupled to electrochemical energy, transport nutrients against a substrate gradient. Facilitative carriers transport sugars along a concentration gradient, thus transport is dependent upon extracellular nutrient levels.

Mitogen-stimulated and rapamycin-sensitive glucose transporter 12 targeting and functional glucose transport in renal epithelial cells.

We hypothesized that glucose transporter 12 (GLUT12) is involved in regulation of glucose flux in distal renal tubules in response to elevated glucose. We used the Madin-Darby canine kidney polarized epithelial cell model and neutralizing antibodies to analyze GLUT12 targeting and directional GLUT12-mediated glucose transport. At physiological glucose concentrations, GLUT12 was localized to a perinuclear position.
