Active clinical trials for "Digestive System Diseases"

Upper digestive tract cancer (UDC) is a major disease burden worldwide encompassing all cancers involving the digestive tract (from oral cavity to duodenum). A majority of patients presenting with this disease are diagnosed late and have poor overall survival rates (<20%). NICE referral guidelines for diagnostic endoscopy are usually associated with late disease. Exhaled breath testing is a non-invasive and acceptable technology utilising mass spectrometry (MS) which has shown promise at diagnosing cancer at an early stage. Previous research has shown that products formed as a result of metabolism can be measured in breath and saliva (biomarkers). This has the ability to accurately identify patients with upper gastrointestinal (UGI) cancers from breath. Our initial pilot data has demonstrated that changes in the breakdown of metabolites release volatile organic compounds (VOC) which can be measured with MS. This data is supported by other patient studies. However no previous study has been performed utilising a non-invasive technique with breath and saliva. Thus the aim of this study is to identify VOCs present in patients with this disease. In this multi-centre study the investigators want to overcome the limitations of previous work by utilising non-invasive samples (breath, saliva and urine) in patients in multiple sites. The investigators aim to conduct a study in patients with UDC and those without. The investigators hope that the results of this study will provide evidence for large scale analysis of patients with this disease, demonstrate the feasibility of this technique and move this valuable test forward into mainstream medical practice. The major advantage of this test is that it is easy to undertake and painless for the patient. This study of products in breath, saliva and urine will be useful for detecting UDC to allow treatment at an early stage, improving overall survival.

The purpose of this study is to elucidate the mechanisms underlying eosinophil growth, survival, migration, and function and to investigate and further characterize the pathophysiology of, clinical manifestations of, and spectrum of disease severity of eosinophilic inflammation in humans.

Development of a new patient reported outcome measure (PROM) that will measure the daily burden of gastrointestinal symptoms over the previous 24 hour period for people with cystic fibrosis.

Functional digestive pathologies are defined by symptoms such as functional dyspepsia, gastroesophageal reflux, irritable bowel syndrome, gastroesophageal reflux, functional constipation, functional diarrhea, functional bloating, the opioid-induced constipation and fecal incontinence, without organic substratum. These diseases are very common in the general population (20%) and represent the first cause of consultation in city gastroenterology. The objective of this study is to collect prospective clinical and tests data and a biological collection from biological samples collected as part of the standard care. This collection could identify diagnostic or prognostic markers of the therapeutic response.

Infants with congenital gastrointestinal anomalies (CGIA) experience multiple physiologic stressors, including neonatal surgery, early in life during an essential time of growth and development. Early physiologic stressors such as inadequate nutrition have been linked to altered growth patterns and neurodevelopmental delays later in life. In other groups of at-risk infants, early body composition measurements can be used as predictors of long-term health outcomes more so than weight and length alone. The primary objective of this study is to determine if body composition changes in early life are predictive of neurodevelopmental outcomes among infants with CGIA. The secondary objective is to determine if infants with CGIA have altered body composition over time when compared with healthy infants. The investigators propose a prospective, observational study of infants with CGIA, including detailed chart review, body composition measurements, and neurodevelopmental testing at follow-up. If a correlation between body composition measurements and neurodevelopmental outcomes is established in this population, the addition of body composition measurement to standard of care in the neonatal intensive care unit and in follow-up care could allow for further optimization of overall health and development of this vulnerable pediatric population through earlier detection of growth alterations and informed interventions.

The goal of this observational study is to learn about the prevalence and characteristics of functional gastrointestinal disorders (FGID) in at risk infants (former preterm infants and those with birth asphyxia) during the first 2 years of life. The main questions it aims to answer are: evaluate the prevalence of symptoms related to GER, of functional gastrointestinal disorders during the first 2 years of life describe growth parameters during follow-up up to the corrected age of 2 years Participants will be assessed clinically and with a structured questionnaire based on the Rome IV criteria to describe FGID.

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EG, EGE and EC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

The purpose of this study was to determine whether computer-driven protocolized weaning is superior to physician-directed non-protocolized weaning in over-24-hours-ventilated surgical intensive care unit (ICU) patients. The main hypothesis was that weaning duration differs between both methods. Secondary hypotheses were that reintubation rate, duration of mechanical ventilation, intensive care unit (ICU) length of stay and workload for physicians and nurses differ between both methods.

A 'digital-first' approach is currently under implementation in several Swedish regions. The principles behind implementing an online service as an access way to primary care are based on an expectation that it can make access easier, direct people to appropriate levels of care, and increase both availability of heath care and cost efficiency. However, a recent Swedish report concluded that digital triage in primary care has not been investigated in a clinical real-world setting, including real patients, meaning that the benefits and risks for patients as well as on a system level remain unclear. The aim of this trial is to study the feasibility of a larger trial that will compare digital triage and traditional telephone triage on adherence to triaged health care level, in a randomized controlled study (feasibility study, RCT). The study will recruit a total of 120 patients, of which half will be randomized to telephone triage and half to digital triage.

The goal of this interventional study is to investigate effects of a2 Full Cream Milk on Breastmilk composition and subsequent Infant gut health, crying frequency and sleep patterns in Healthy Full-term Infants. 50 mothers and thier infants will be enrolled into 2 study sites, mother and her child as one subject will be randomized to 2 groups for assigned interventions, a2 Full Cream Milk and conventional Milk (Weidendorf). The study will continue for 14 days, and 3 site visits will be made duing the study period. All data specified in the protocol will be captured and recorded into CTMS for analysis. Researchers will compare the two groups of participants to see if a2 Full Cream Milk has significantly better breastmilk composition and improve infant's gut health, crying frequency and sleep patterns.
