Active clinical trials for "Gastrointestinal Diseases"

The study aim is to diagnose patients with the rumination syndrome defined by the Rome IV criteria and to treat them with behavioral therapy consisting of diaphragmatic breathing exercises and physiotherapy to relax tensed abdominal and thoracic muscles. Before referral to the study, gastroscopy, esophageal hgh-resolution manometry and 24-hour esophageal pH and impedance monitoring are required to rule out other esophageal conditions. Twenty Finnish speaking, 15-70 years old patients will be enrolled in this open study. All patients will visit the gastroenterologist at onset of the study and at 6 months. All patients will be referred to the speech therapist for five one-hour sessions consisting of diaphragmatic belching exercises and to the physiotherapist for two one-hour sessions consisting of exercises to relax tensed thoracic and abdominal muscles. All patients will also visit once the psychologist and dietician. Symptoms will be evaluated by the Rome IV questionnaire for adult functional gastrointestinal diseases at onset and at the 6-month control. Health-related quality of life, depression, anxiety, functional capacity will be evaluated by specific questionnaires at onset of the study and at the 6-month control. Esophageal high-resolution manometry will be performed at the 6-month control.

Recommendations for carbohydrate intakes in the pre-exercise meal for endurance athletes are available; however, are lacking protein. Therefore, the purpose of this study is to quantify exercise-induced gastrointestinal symptoms and gut fullness occurring in response to a low protein (control) and a high protein (intervention) pre-exercise meal. The secondary purpose is to quantify blood glucose responses to a high-protein pre-exercise meal as compared to a low-protein control.

The aim of the current study, embedded in The Danish FGID Treatment Study, is to test Danish versions of Swedish i-CBT programs for children and adolescents with FGID in a Danish clinical context and to further evaluate the presence and impact of important psychological and parental factors.

Background: Bladder and bowel dysfunction (BBD) is characterized by lower urinary tract symptoms accompanied by bowel complaints. BBD is a common condition in childhood. The present treatment strategy for BBD is a step-wise approach starting with management of bowel symptoms before initiation of standard urotherapy and further medical treatment of LUTS symptoms. This is, however, based on clinical experience and few retrospective, non-randomized studies and high-level evidence of the succession of the elements in treatment of BBD children is missing. Our microbiome, and its role in health and disease, has gained increased focus during the past years. Studies suggest the urine and gut microbiome to be critical for maintenance of a well-functioning bladder- and bowel system. The microbiome in children is only sparsely investigated and its role in BBD is to the investigator's knowledge still unexplored. Study 1: Aim: To investigate if combination therapy is more effective in treating urinary incontinence in BBD children. Materials and methods: A prospective randomized multicentre study on children with BBD (n=100) between 5-14 years and 9 months old. They are randomized to: 1) Medical treatment of bowel symptoms (n=50) or 2) Medical treatment of bowel symptoms combined with standard urotherapy. The effect of treatment will be evaluated after 3 months. Primary endpoint: Resolution of incontinence after treatment. Secondary endpoint: Improved quality of life after successful treatment of urinary incontinence. Study 2: Aim: To investigate the urofecal microbiome in children with BBD Materials and methods: A cohort study to investigate, whether the urofecal microbiome can predict response to treatment and whether it changes during treatment period A case control study to investigate whether the urofecal microbiome is different in children with BBD and recurrent UTI 's and children with BBD without recurrent UTI 's. The study population consists of children with BBD included in study 1. A urine-, stool sample and a perineum swab will be collected from all participants before and after treatment. Bacterial DNA will be extracted and the microbiome will be determined. Perspectives: BBD is a common condition in childhood. It is associated with a considerable psychological burden and a risk of more severe physical complications. The studies will provide basic knowledge about characteristics of the BBD patients and contribute new information about the optimal treatment of BBD children.

This research project aims to test whether early interventions delivered remotely and prior to integrated care clinic appointments are effective. Patients with chronic unexplained gastrointestinal symptoms will initially undergo structured assessment of symptoms and wheat intolerance delivered remotely. Patients who continue to experience symptoms will then be randomised to a pre-consultation intervention ((a) standardised dietician supervised intervention, b) exercise intervention, c) internet delivered cognitive behavior therapy or d) nothing) followed by randomisation to the consultation intervention ((a) consultant-led outpatient clinic or b) a integrated care clinic depending on their response to the initial intervention.

Elderly people (EP) have increased, as well as life expectancy at birth. In Chile there are more than 2 million 800 thousand EP, which corresponds to 1/6 of the Chilean population. The EP have a higher disease burden and mortality when facing surgery and in the postoperative period. Thus, this population frequently has longer hospital stays due to its degree of fragility, surgical complications or decompensation of its underlying pathologies, directly affecting health care systems. An inadequate preparation of the EP prior to surgery determined that the requirements of in-hospital as well as out-of-hospital care are extended, with the consequent which entails a higher cost in health. Current research underestimates the conditions of frailty and dependence in the EP. In addition, it is not routinely evaluated prior to surgery, as well as nutritional, metabolic, cognitive status and / or delirium screening is performed. There are accelerated recovery programs, which relate their interventions to specific pathologies; however, the age of the person is not taken into account. Surgical pre-habilitation interventions in the EP usually focus their efforts on physical and cardiovascular aspects, not including an integrative pre-surgical evaluation. Based on the foregoing, a prospective, interventional, longitudinal and randomized study has been proposed in a population of the EP who will undergo elective urology and coloproctology surgeries in two university hospitals (private and public). The objective of this study is to evaluate how the implementation of a timely pre-surgical conditioning (APO) protocol for frail elderly people reduces the days of hospital stay. The APO considers the most relevant aspects of physical and cardiovascular pre-habilitation, in addition to contemplating evaluations of frailty, dependence, cognitive status, screening for delirium, nutritional and metabolic.

This is a randomized, controlled, parallel, multicenter trial to determine the difference in post-operative anastomotic leakages in colorectal surgery, where anastomosis perfusion is evaluated using indocyanine green fluorescence imaging as an addition to standard surgical practice compared to surgical practice alone.

The purpose of this study is find out if we can use simple tests (biomarkers) to tell us if a specific child would benefit most from CBT or from the low FODMAPs diet.

Functional dyspepsia is common, affecting 7.2% of the global population, and associated with substantial health impairment. Almost 80% of patients with functional dyspepsia report meal-related symptoms and are classified as having the postprandial distress syndrome (PDS) variant. However, studies evaluating dietary modifications in PDS are sparse. The investigators will perform a randomised trial evaluating traditional dietary advice (TDA) vs. a diet low in fermentable fermentable oligo-, di-, mono- saccharides and polyols (low FODMAP diet) in PDS. 70 patients with PDS will be randomly assigned TDA or a low FODMAP diet. The TDA group will be recommended to eat small, regular meals and reduce the intake of caffeine/alcohol/fizzy drinks, fatty/processed/spicy foods, and fibre. The low FODMAP diet group will be advised to exclude fermentable carbohydrates, which are present in wheat-based products, many fruits/vegetables, pulses, beans, dairy, and sweeteners. Questionnaires are to be completed during the 6-week trial, including self-reported adequate relief of dyspeptic symptoms, and the validated Leuven Postprandial Distress Scale (LPDS), Gastrointestinal Symptom Rating Scale, and Nepean Dyspepsia Quality of Life Index. The primary endpoint to define clinical response will be evaluated over weeks 4-6 as >0.5-point reduction in the PDS subscale of the LPDS (calculated as the mean scores for early satiety, postprandial fullness, and upper abdominal bloating).

Functional dyspepsia is common, affecting 7.2% of the global population, and associated with substantial health impairment. Almost 80% of patients with functional dyspepsia report meal-related symptoms and are classified as having the postprandial distress syndrome (PDS) variant. However, studies evaluating dietary modifications in PDS are sparse. The investigators will perform a single-centre randomised trial evaluating traditional dietary advice (TDA) in PDS. 50 patients with PDS will be randomly assigned to a leaflet explaining reassurance-alone +/- TDA. The reassurance-alone group will be informed of the absence of organic disease and provided a diagnostic explanation of functional dyspepsia. The TDA group will receive the same information but also be recommended to eat smaller, regular meals and reduce the intake of caffeine/alcohol/fizzy drinks, fatty/processed/spicy foods, and fibre. Questionnaires are to be completed during the 4-week trial, including self-reported adequate relief of dyspeptic symptoms, and the validated Leuven Postprandial Distress Scale (LPDS), Gastrointestinal Symptom Rating Scale, and Napean Dyspepsia Quality of Life Index. The primary endpoint(s) to define clinical response will be evaluated over weeks 3-4 as, i) ≥50% adequate relief of dyspeptic symptoms, and ii) >0.5-point reduction in the PDS subscale of the LPDS (calculated as the mean scores for early satiety, postprandial fullness, and upper abdominal bloating).
