Active clinical trials for "Constipation"

To compare the frequency of regurgitation and other digestive outcomes between infants who receive an infant formula based on whole goat milk and an infant formula based on cow milk proteins during the transition period from breastfeeding to formula feeding, using predominantly breastfed infants as a reference group.

It has been determined that three out of every four people in the society do not have sufficient physical activity level, and 54% of individuals between the ages of 15-19 and over 55 are sedentary. As a result of this, the probability of encountering the problem of constipation may increase. There are many methods in the treatment of constipation. When examined in terms of exercise interventions, it was found that 150 minutes of moderate-intensity exercise per week was effective in reducing the symptoms of constipation, while aerobic exercise performed less than 140 minutes/week did not improve the symptoms of constipation. It has been reported that individuals who received defecation training were particularly successful in the management of constipation symptoms. In our study, it is aimed to examine the effectiveness of exercise interventions for constipation. In addition, to the best of our knowledge, no study has been conducted on the effectiveness of a telerehabilitation-based education and exercise program in patients with constipation. It is thought that the management of patients with constipation with telerehabilitation will ease the burden on the health system, while it will save the patient cost and time, and will facilitate the access to treatment for patients living in geographically disadvantaged areas. In addition, it is important for patients to participate in distance rehabilitation studies in their professional and social lives, as it is an innovative treatment approach. It is thought that the exercises for constipation applied in addition to the training program may be a more effective method in improving the quality of life and colonic motility of the patients.

More than 70% of patients with cancer in the palliative phase have pain that often requires treatment with opioids (morphine-like agents). Constipation occurs in 59% of patients treated with opioids. Opioid-induced constipation (OIC) has consequences that range from daily discomfort with social insecurity and disability to intestinal obstruction. It leads to limitations in self-management, a reduced quality of life and a risk of the need for more care. In the guideline "Diagnosis and treatment of pain in patients with cancer" it is recommended to start preventively with an osmotic laxative such as macrogol/electrolytes or magnesium hydroxide when starting opioids. Macrogol/electrolytes has been proven to be effective for OIC, but is sometimes perceived by patients as unpleasant due to its taste. Magnesium hydroxide, which is less commonly prescribed for OIC, has a neutral taste. Although it is mentioned in the guideline, it is not studied for the treatment of OIC and also not officially registered for this. To support the advice of the guideline and to prove that a choice is possible, it is important to investigate whether there are differences in effectiveness and/or side effects between macrogol/electrolytes and magnesium hydroxide in the prevention of OIC. The aim of this study is to compare macrogol/electrolytes with magnesium hydroxide in the prevention of opioid-induced constipation in patients with cancer in the palliative (incurable) phase, who start opioids because of pain. The choice of laxative is determined by drawing lots (randomisation). After two weeks, its effect will be assessed and will be presented as the percentage of patients who have not developed constipation after starting opioids. If the laxative, as assigned by lot, is described as satisfactory by the patient, the patient can continue with the drug that the patient used, after the study through regular prescription. The investigators will ask the patients in the study about their satisfaction with the laxative used, any side effects and the degree of pain. Furthermore, the appeal to care for possible constipation will be examined. Because the best attainable quality of life in the palliative phase is the objective of all care, the investigators will also measure this perceived quality with a questionnaire in this study. The results of this study will lead to the best achievable prevention of opioid constipation in patients with cancer in the palliative phase.

Chronic constipation (CC) is a common condition that affects up to 25% of the population in North America. It poses a major burden on the healthcare cost. The pathophysiology of this condition is poorly understood and consequently there are inadequate treatments. Current diagnostic tests provide incomplete and often conflicting information. Fecobionics is an electronic simulated stool that has the consistency and shape of normal stool. The device records pressures, cross-sectional area, orientation, bending, and shape of the rectum and anal canal simultaneously. The central hypothesis is that rectal peristalsis is a key component of the defecatory reflex which is not assessed in the current paradigm of diagnostic testing. The novel Fecobionics device will mimic the natural defecation and provide new mechanistic insights into the anorectal physiology and pathophysiology to facilitate the development of new treatments for CC. The Specific Aims are as follows: 1) Study the defecation dynamics in normal control subjects using Fecobionics. The investigators will establish the role of rectal contraction/peristalsis in the normal evacuation process. 2) Define the defecatory patterns in patients with CC associated with defecatory disorders. The investigators will determine if abnormalities of rectal contraction contribute to the CC. 3) Use a mathematical model of anorectal passage of Fecobionics for enhanced understanding of the normal and abnormal defecatory patterns, including the length-tension properties of the rectum and anal sphincter muscles. The proposal seeks to shift current CC research by providing a stool surrogate for examining the physiologic parameters of defecation reflex using a novel device that will record, pressure, deformability, biomechanics, vectoral and topographic changes in the rectum and anal canal. The noted parameters will be recorded using a wireless Fecobionics device that can examine in detail the mechanistic underpinnings (stress and deformation) of defecation reflex/process in health and disease. The impact of this project is that it assesses a novel, safe, low cost, less invasive, low-risk, radiation-free device in its ability to provide better understanding of evacuation and continence mechanisms and thereby facilitate future development of innovative therapies. The improvement can lead to improvement in diagnostic and therapeutic modalities and reduce healthcare costs associated with anorectal disorders.

To gain a better understanding of the underlying dysmotility in constipation in children, we will use a novel minimal invasive method called 3D Transit. We will examine four groups of children aged 7 to 17 years: healthy children, chronically constipated children (ROM IV criteria), children with neurofibromatosis type 1 and finally children receiving chemotherapy (vincristin) for acute lymphoblastic leukemia.

LIN-MD-66 is a Phase 3 open-label study with 24 weeks (Functional Constipation participants) or 52 weeks (Irritable bowel syndrome with constipation participants) of linaclotide exposure that will enroll pediatric participants (6-17 years of age) with FC or IBS-C who completed study intervention in studies LIN-MD-62, LIN-MD-63, orLIN-MD-64 based on the individual study criteria.

Constipation is a common reason of poor bowel preparation, which negatively influences the quality of colonoscopy. Clinically to explore more effective and tolerant bowel clearance programs is necessary for patients with chronic constipation.

Defecatory disorders like chronic constipation and faecal incontinence affect 25% of the population with rising incidence. Defecatory disorders pose a major health care burden and are poorly recognized and treated. The need for better diagnostics and therapeutics is substantial. Current assessment of patients with constipation and faecal incontinence include endoscopic assessment to rule out intraluminal organic cause for patients' symptoms, endoanal ultrasound scan / MRI to assess patients' pelvic floor anatomy and anorectal manometry and balloon expulsion test to assess anorectal function. All tests are susceptible to measurement artifacts. The standard technologies for anorectal assessment are anorectal manometry, balloon expulsion test and defecography. Endoluminal Functional Lumen Imaging Probe (EndoFLIP©) is a novel technology, originally used to measure the dimensions and function of a hollow organ. Anorectal manometry, balloon expulsion test, defecography, and the EndoFLIP probe will be used in the proposed studies. In addition, the proposed study intends to use a simulated feces named Fecobionics which is a device that integrates several technologies into one which will save time and reduce test variability. In the proposed studies investigators will assess defecatory function in subgroups of Hong Kong patients suffering from chronic constipation and faecal incontinence and determine biomarkers to increase the diagnostic value of anorectal testing. Investigators will study up to 130 patients with anorectal disorders and 101 healthy control subjects. Investigators anticipate to improve diagnostics of anorectal disorders considerably and to learn about physiological mechanisms that affect defecatory efficacy.

Functional constipation (FC) is a common condition associated with aging, lower socioeconomic status, low physical activity and also with reduced fibre, water and magnesium intakes. Different studies have reported a positive association between the intake of hyper-mineral water containing a high content of bicarbonate, calcium, or magnesium, and the improve of the gastrointestinal transit. There is evidence that magnesium and sulphate, both individually, have a laxative action. However, the impact of other minerals is scarce. It has been described different mechanisms explaining how gut microbiota influence the gastrointestinal transit. Specifically, in FC patients, it is important to understand the particularities of their gut microbiota and understand whether the intake of hyper-mineral water, a natural source of minerals, can modify positively the gut microbiota. The aim of the present randomized placebo-controlled pilot trial is to evaluate, for the first time, the effect of the carbonated mineral water consumption in the gastrointestinal transit and in the gut microbiota of subjects with FC.

Patients with constipation are more likely to have poor bowel preparation quality due to slow gut motility and poor emptying ability. Gum chewing, as a proxy of sham feeding, is a very simple way used to accelerate gut motility. And a previous study found that enhanced instructions by WeChat could improve bowel preparation quality. Thus, investigators conducted a single-center randomized controlled trial to explore the effect of chewing gum combined with manual enhanced instructions by WeChat on the bowel preparation quality for colonoscopy in patients with constipation.
