Background: In functional gastrointestinal disorders a lack of objective biomarkers limits evaluation of underlying mechanisms. We aimed to demonstrate the utility of Magnetic Resonance Imaging (MRI) for this task using psyllium, an effective constip...

As we learn more about the importance of our microbiome in inflammatory, metabolic, and functional disorders, we are coming to appreciate the risks of disturbing this with broad-spectrum antibiotics. We have known for many years that as antibiotics h... Read More about Hidden dangers of antibiotic use: increased gut permeability mediated by increased pancreatic proteases reaching the colon.

Insights into the different effects of food on intestinal secretion using magnetic resonance imaging (2018)
Journal Article

Insights into the different effects of food on intestinal secretion using magnetic resonance imaging. Journal of Parenteral and Enteral Nutrition, 42(8), 1342-1348. https://doi.org/10.1002/jpen.1157

Background

Ileostomy output determines need for parenteral fluid support. Plant foods may contain chemicals that stimulate intestinal secretion eg. lactucins in lettuce and rhein in rhubarb. These may account for increases in ileostomy output but... Read More about Insights into the different effects of food on intestinal secretion using magnetic resonance imaging.

Cortical differences in diverticular disease and correlation with symptom reports (2018)
Journal Article
Pitiot, A., Smith, J. K., Garratt, J., Francis, S. T., Gowland, P. A., Spiller, R. C., & Marciani, L. (2018). Cortical differences in diverticular disease and correlation with symptom reports. Neurogastroenterology and Motility, 30(7), Article e13303. https://doi.org/10.1111/nmo.13303

Background

Recent studies have shown that the brain of patients with gastrointestinal disease differ both structurally and functionally from that of controls. Highly somatizing diverticular disease (HSDD) patients were also shown to differ from l... Read More about Cortical differences in diverticular disease and correlation with symptom reports.

The rate and extent of drug dissolution and absorption from solid oral dosage forms is highly dependent on the volume of liquid in the gastrointestinal tract (GIT). However, little is known about the time course of GIT liquid volumes after drinking a...
