7 Clinical Trials for Various Conditions
The objective is to determine the length-tension properties of the anal sphincters using Fecobionics in normal subjects and FI patients during anal distension and during simulated evacuation. Fecobionics has the consistency and shape of normal stool and can record pressures, cross-sectional area, orientation and viscoelastic properties of the anorectum and can map the geometric profiles during evacuation, and thereby provides multi-dimensional measurements of pressures, deformability, and topographic changes. Fecobionics combines several existing tests to provide novel insight into anorectal function. The purpose for the development was to overcome the technological controversies and disagreement between various tests and unphysiological test conditions. The aim was to imitate defecation as much as possible to the natural process. Fecobionics was developed to simulate stool and to provide the driving pressure and resulting deformations of stool along with a measure of an objective anorectal angle during defecation in a single examination. Fecobionics makes it possible to describe objectively, without disturbing the defecation process, the opening characteristics and pressure signatures during initial entry into the relaxing anal canal. The overall goal is to provide mechanistic understanding of defecation in health and defecatory disorders. It exceeds previous attempts to make artificial stool for evaluation of defecation (BET and FECOM) and integrates other technologies as well. It was designed to have a consistency and deformability of Type 4 (range type 3-5) on the Bristol stool form scale. The range from types 3-5 is found in 70% of normal subjects. A major novelty is that Fecobionics measures pressures in axial direction; i.e., in the flow direction.
Multicenter, prospective, non randomized, single arm evaluation of patients with overactive bladder (OAB) and/or fecal incontinence (FI) employing the Axonics recharge free SNM System.
The purpose of this study is to determine the effect of fiber supplementation on the fecal metagenome and metabolome in relation to symptoms and anorectal physiology in post-menopausal women with irritable bowel syndrome with diarrhea suffering from liquid stool fecal incontinence (FI.)
Fecal Incontinence (FI) affects 40 million Americans, predominantly women and elderly. It is a major health care burden, significantly impairs quality of life and psychosocial function. FI is characterized by multifactorial dysfunction including lumbosacral neuropathy, anorectal sensori-motor dysfunction, and abnormal pelvic floor-brain innervation. A critical barrier to progress in the treatment of FI is the lack of RCTs, absence of mechanistically based non-invasive therapies that modify disease, and a lack of understanding on how treatments affect pathophysiology of FI. Consequently, most current remedies remain ineffective. Our long-term goal is to address the problem of lack of effective treatments for FI by investigating treatments that modulate neuronal perturbations and thereby improve sensory and motor control, and to understand the neurobiologic basis of these treatments. Our central hypothesis is that a novel, non-invasive treatment consisting of Translumbosacral Neuromodulation Therapy (TNT), using repetitive magnetic stimulation, will significantly improve FI in the short-term and long-term, by enhancing neural excitability and inducing neuroplasticity. Our approach is based on compelling pilot study which showed that TNT at 1 Hz frequency, significantly improved FI, by enhancing bidirectional gut- brain signaling, anal sphincter strength and rectal sensation compared to 5 or 15 Hz. Our objectives are to 1) investigate the efficacy, safety and optimal dose of a new treatment, TNT, in a sham controlled, randomized dose-dependent study in 132 FI patients; 2) determine the mechanistic basis for TNT by assessing the efferent and afferent pelvic floor-brain signaling, and sensori-motor function; 3) identify the durability of treatment response and effects of TNT, and whether reinforcement TNT provides augmented improvement, by performing a long-term, sham controlled randomized trial. Our expected outcomes include the demonstration of TNT as a durable, efficacious, safe, mechanistically based, non-invasive, and low risk treatment for FI. The impact of our project includes a novel, disease modifying, non-invasive treatment, a scientific basis for this treatment, and improved understanding of the pathophysiology of FI and how TNT modifies bidirectional gut and brain axes and anorectal function. Ultimately, the knowledge generated by this project will provide new avenues for the development of innovative, evidence-based therapies for FI.
Investigators will conduct a single-arm pre-post intervention pilot study in 46 older women with Fecal Incontinence (FI), also known as Accidental Bowel Leakage (ABL). FI symptoms and stool metabolites will be measured at baseline. Intervention with the Diet Modification Program (DMP) will be administered. FI symptoms and stool metabolites will be measured after 6weeks of the intervention.
Fecal Incontinence (FI) is a debilitating and common condition with a prevalence ranging from 7-15% in community dwelling women. FI has an immense impact on quality of life and is associated with increased care giver burden, increased rates of institutionalization, and significant cost burden in older women. Traditionally believed to be primarily caused by child birth injury, recent studies show that the typical age of onset of FI is age 40 which is remote from child birth. Treatment options for FI are limited because the mechanism underlying FI in older women are poorly understood. The overriding goal of this project is to investigate the relationship between diet, stool metabolites and fecal incontinence.
Fecal incontinence is the involuntary leakage of stool from the anus. Doctors at Mayo Clinic are doing a research study to assess the effects of a medication, clonidine, on fecal incontinence and rectal functions in women. Clonidine has been approved by the Food and Drug Administration (FDA) for treating high blood pressure, but not for treating incontinence and rectal functions. The hypothesis of this study is clonidine will improve fecal incontinence, increase rectal capacity and reduce rectal sensation to a greater extent than placebo in women.
