Summary
Faecal incontinence (accidental bowel leakage) is a common problem in the Australian community with devastating impacts on quality of life and psychological well-being. Treatment of this condition remains a challenge due to limited scientific knowledge. Sacral nerve modulation (electrostimulation of nerves in the lower back) is an exciting new treatment but we don’t understand how it works. This project aims to improve our understanding of how nerve stimulation improves symptoms.
A Practice Change For Patients With Severe Chronic, Clinically Unexplained Gastrointestinal Symptoms: A Randomised, Controlled Intervention To Assess Efficacy And Cost-effectiveness

Funding Amount
$1,276,080.00
Summary
Unexplained chronic gastrointestinal symptoms are extremely common and costly to the health system. Currently patients are managed in the hospital setting with the 'typical' face-to-face office-based model which sees the clinician spending valuable time gathering information and often treatments (e.g. allied health) delivered in a non-standard way. This project will evaluate the effectiveness of a new standard best-practice clinical model with a structured technology enabled management approach.
Identification And Characterisation Of Sensory Receptors In The Human Rectum

Funding Amount
$69,500.00
Summary
Normal rectal function (with respect to storage and evacuation of faeces) is highly dependent on intact rectal sensation. Identification and characterisation of biomarkers of rectal sensation in health would allow more accurate diagnosis and a better understanding of prevalent bowel disorders, such as constipation and faecal incontinence. It would also give opportunity to identify potential novel therapeutic targets, and accurately assess the efficacy of existing and new treatment strategies.

This proposal will investigate the electrical properties of neurons in the wall of the intestine that control movements of the bowel. These neurons form an extensive network that runs the length of the gastrointestinal tract and control mixing and propulsion of food along the intestine. We will determine the basic electrical properties of these neurons and investigate why some of them transmit signals in a continuous manner while others transmit signals intermittently and how these patterns of a ....This proposal will investigate the electrical properties of neurons in the wall of the intestine that control movements of the bowel. These neurons form an extensive network that runs the length of the gastrointestinal tract and control mixing and propulsion of food along the intestine. We will determine the basic electrical properties of these neurons and investigate why some of them transmit signals in a continuous manner while others transmit signals intermittently and how these patterns of activity fit into the overall activity of the gut. This study will build on a large body of data obtained from our laboratory that has shown that some of these neurons act as sensors of the presence-absence of food in the intestine while others send signals to the muscle in the wall of the intestine to either relax or contract it so that the food can be processed properly. By knowing what makes these neurons different from each other we will be able to understand what goes wrong in functional bowel disorders where motility is affected, resulting in pain and discomfort.Read moreRead less
The applicant aims to improve treatment of digestive disease by identifying and understanding the interactions between the nervous system and the gastrointestinal (GI) tract, with emphasis on sensory systems.
A vitamin-sized capsule, containing gas sensors, is to be fully developed for assessing the state of health and diagnosing the diseases relevant to gastrointestinal tract. The capsule travels along the tract, transmitting information about the gas species generated by the microorganisms of the gut, which is closely associated with the health of the human under surveillance. The information will be invaluable for diagnostics and adjusting the diet to mitigate and cure the diseases of the guts.
