Seated anorectal manometry during simulated evacuation. A physiological exercise or a new clinically useful diagnostic test? (2020)
Journal Article

Symptoms such as a feeling of incomplete evacuation, straining, absence of the call to stool, anal blockage or digitation suggest the presence a functional defecation disorder. As symptoms do not distinguish between patients with and without function... Read More about Seated anorectal manometry during simulated evacuation.

Unraveling the behavior of oral drug products inside the human gastrointestinal tract using the aspiration technique: history, methodology and applications (2020)
Journal Article

Fluid sampling from the gastrointestinal (GI) tract has been applied as a valuable tool to gain more insight into the fluids present in the human GI tract and to explore the dynamic interplay of drug release, dissolution, precipitation and absorption...

The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge (2020)
Journal Article

Background Magnetic resonance imaging (MRI) of the colonic response to a macrogol challenge drink can be used to assess the mechanisms underlying severe constipation. We measured the intra-subject reproducibility of MRI measures of colonic funct... Read More about The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge.

Patient-Specific Stress–Abdominal Pain Interaction in Irritable Bowel Syndrome: An Exploratory Experience Sampling Method Study (2020)
Journal Article

INTRODUCTION: Gastrointestinal symptoms in irritable bowel syndrome (IBS) have been correlated with psychological factors using retrospective symptom assessment. However, real-time symptom assessment might reveal the interplay between abdominal a...

Manometric demonstration of duodenal/jejunal motor function consistent with the duodenal brake mechanism (2020)
Journal Article

© 2020 John Wiley & Sons Ltd Background: High-resolution manometric studies below the stomach are rare due to technical limitations of traditional manometry catheters. Consequently, specific motor patterns and their impact on gastric and small bowe...

Treatment of Irritable Bowel Syndrome with diarrhoea using Titrated Ondansetron (TRITON): study protocol for a randomised control trial (2019)
Journal Article

Background – Irritable bowel syndrome with diarrhoea (IBS-D) affects up to 4% of the general population. Symptoms include frequent, loose, or watery stools with associated urgency, resulting in marked reduction of quality of life and loss of work pro...

How to select patients for anti-reflux surgery? The ICARUS guidelines (International Consensus regarding preoperative examinations and clinical characteristics assessment to select adult patients for AntiReflUx Surgery) (2019)
Journal Article

Objective: Anti-reflux surgery can be proposed in patients with gastro-esophageal reflux disease, especially when proton pump inhibitor use leads to incomplete symptom improvement. However, to date, international consensus guidelines on the clinical... Read More about How to select patients for anti-reflux surgery? The ICARUS guidelines (International Consensus regarding preoperative examinations and clinical characteristics assessment to select adult patients for AntiReflUx Surgery).

First translational consensus on terminology and definitions of colonic motility in animals and humans studied by manometric and other techniques (2019)
Journal Article

Alterations in colonic motility are implicated in the pathophysiology of bowel disorders, but high-resolution manometry of human colonic motor function has revealed that our knowledge of normal motor patterns is limited. Furthermore, various terminol... Read More about First translational consensus on terminology and definitions of colonic motility in animals and humans studied by manometric and other techniques.

“Development of Fixed Dose Combination Products” Workshop Report: Considerations of Gastrointestinal Physiology and Overall Development Strategy (2019)
Journal Article

The gastrointestinal (GI) tract is one of the most popular and used routes of drug product administration due to the convenience for better patient compliance and reduced costs to the patient compared to other routes. However, its complex nature pose... Read More about “Development of Fixed Dose Combination Products” Workshop Report: Considerations of Gastrointestinal Physiology and Overall Development Strategy.

Defecatory urge increases cognitive control and intertemporal patience in healthy volunteers (2019)
Journal Article

Background: Past research has demonstrated that moderate urge to urinate improves inhibitory control, specifically among participants with higher behavioral inhibition sensitivity (BIS). The effect was absent when the urge exceeded intolerable level.... Read More about Defecatory urge increases cognitive control and intertemporal patience in healthy volunteers.

The mechanisms of pharmacokinetic food-drug interactions: A perspective from the UNGAP group (2019)
Journal Article

The simultaneous intake of food and drugs can have a strong impact on drug release, absorption, distribution, metabolism and/or elimination and consequently, on the efficacy and safety of pharmacotherapy. As such, food-drug interactions are one of th... Read More about The mechanisms of pharmacokinetic food-drug interactions: A perspective from the UNGAP group.

Targeting mu opioid receptors to modulate gastrointestinal function: what have we learnt so far from the studies in functional bowel disorders? (2019)
Journal Article

Opioids have recently received much attention because of the epidemic in their use in some countries such as the USA and the UK. Concerns have been raised about the possibility that they can increase mortality in patients when used on a long-term bas...

Prevalence and impact of self-reported irritable bowel symptoms in the general population (2018)
Journal Article

Background and aims The symptom-based diagnostic criteria for irritable bowel syndrome (IBS) have recently been revised in the Rome IV consensus. On the other hand, with rising public awareness of IBS, self-diagnosis and self-management is also incr...

Will MRI of gastrointestinal function parallel the clinical success of cine cardiac MRI? (2018)
Journal Article

Cine cardiac MRI is generally accepted as the “gold-standard” for functional myocardial assessment. It only took a few years after the development of commercial MRI systems for functional cardiac imaging to be developed, with electrocardiogram (ECG)-...
