Filter by: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.
To clarify the changes of intestinal flora - gut - brain axis in FGIDs patients represented by NERD disharmony of liver and stomach and IBS-D disharmony of liver and spleen, and confirm that the imbalance between intestinal flora and host co-metabolism is the key to the pathogenesis of functional gastrointestinal disease. To reveal the common mechanism of regulating liver and spleen (stomach) in treating FGIDs dynamic disorder and visceral hypersensitivity by regulating intestinal flora - intestine - brain axis disorder.
Are you what you eat? How can dietary components influence microbial composition of the gut and function of the peripheral and central nervous system? The gut and brain is linked through complex mechanisms of sensorimotor functions of the immune system, the hypothalamic-pituitary-adrenal-axis, the enteric nervous system and microbiota. In this project, a multitude of factors contributing to the bidirectional neurobiological communication along the brain-but-axis will be investigated. No disease of the brain-gut axis has been elucidated, therefore our investigations involves approaching a large span of components and processes involved in the axis. This study is carried out as a case-report study (baseline, IBS n=100, healthy controls n=40) followed by a dietary intervention (IBS-D n=60). Through multivariate analyses, the investigators will identify patterns of factors contributing to patient symptomatology and pathology, followed by big data analysis leading to stratification of sub-classification of irritable bowel syndrome (IBS).
To analyze the classification characteristics of gastrointestinal symptoms, the quality of life, the degree of anxiety and depression, and the satisfaction with the treatment of Chinese medicine in patients with FGIDs in Chinese Grade-A Tertiary Hospitals. The characteristics of TCM（Traditional Chinese Medicine） syndromes and symptoms of the above-mentioned FGIDs will be analyzed, and the characteristics of TCM syndromes of FGIDs and their possible relationship with FGIDs subtypes will be analyzed.
The purpose of this study is to develop and validate a deep learning algorithm for the diagnosis of gastrointestinal diseases. Then, evaluate the accuracy this new artificial intelligence(AI) assisted recognition system in clinic practice.
The investigators will conduct a multicenter cross-sectional study to discover symptom characteristics, quality of life, severity of anxiety and depression, status of lactose intolerance and treatment satisfaction of current Chinese Medicine (CM) regimens of outpatients with FGIDs. In the meanwhile, the investigators will also analyze the characters of CM patterns and corresponding elements, then explore the potential relationship between CM patterns and FGIDs' subtypes.
Non-randomized monocentric open cohort study vs historical comparative group testing the efficacy of a multimodal prehabilitation program (based on physical activity, nutritional support and mental preparation) for unfit patients based on nutrition, physical activity and mental preparation in reducing postoperative complications in elective major surgery
Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) (categorised into Crohn's disease (CD) and ulcerative colitis (UC)) are chronic gut disorders with debilitating symptoms that profoundly impact quality of life, healthcare systems and the economy through lost work days. IBS is common with a prevalence of up to 22%, whereas IBD has a prevalence of 0.3% for CD and 0.5% for UC in Europe. Despite a suggested immunological and genetic aspect of IBD, the causes of IBS and IBD are unknown, however, both have been linked to yeasts in the gut. Due to their lower abundance (constituting only around 0.1% of the total microorganisms in the gut) yeasts have been less studied than bacteria. More recently, significantly altered diversity and composition of yeasts have been identified in IBS and IBD but further investigation is required to fully develop the role of yeasts in the gut. This observational study will assess yeasts and their function in the gut, comparing diseased subjects with healthy controls. The overall aim is to determine if yeasts could be targeted as a potential therapeutic for IBS and IBD to provide relief to sufferers as well as reducing the burden on healthcare systems.
Digestive Functional Disorders (DFD), represent 50% of medical check ups, the symptoms interfere with patients quality of life and generate high health costs. On the other hand, with the worldwide overweight and obesity increase,causing an over production of low-calorie products, which increase the non-caloric sweeteners (NCS) consumption. Hypothesis: A diet without NCS will reduce gastrointestinal symptoms in volunteers with dyspepsia and IBS. Objective: To asses the effect of a diet without NCS, on the gastrointestinal symptoms in patients with dyspepsia and IBS. Secondary Objectives: To compare the effect of a diet without NCS against a diet with NCS on anthropometry, changes in body composition, biochemical parameters, glucose and insulin. To asses the change in the gut microbiota using real-time PCR (polymerase chain reaction) Methodology: it will be an experimental, open, parallel, controlled study lasting 12 weeks, patients with dyspepsia or IBS will be randomized assigned to a diet with or without NCS. Laboratory studies, dietary and symptoms questionnaires, anthropometry measurements and faecal sample will be carried out. Analysis Results: A double data capture will be carried out to minimize errors, for the statistical analysis of using the Statistical Package for the Social Sciences (SPSS) version 25, descriptive statistics will be used to report the baseline data of the volunteers. Using means and standard deviation, the variables of gastrointestinal symptoms will be used a chi-square test and a p <0.05 will be considered significant. Different analyzes will be done to evaluate volunteers with IBS and those with dyspepsia. For the intestinal microbiota analysis, a comparison will be made between the percentages of Firmicutes, Bacteroidetes and Actinobacteria of sample 1 and 2 and a chi-square test will be performed considering a p <0.05 significant
People affected central nervous system (CNS) diseases often suffer from neurogenic bowel dysfunction (NBD) that causes a reduction in the quality of life and participation in social life. Although some conservative approaches exist to treat NBD, none has shown to be effective in managing this complex condition. Osteopathic manipulative treatment (OMT) has shown to be efficient in CNS diseases such as epilepsy and migraine. This randomised trial aims at evaluating the efficacy of osteopathic manipulative treatment (OMT) in supporting the management of NBD. The research will be conducted at the outpatient service of Neuro-Urology / Spinal Unit of the Città della Salute e della Scienza Hospital of Torino. A sample of 62 participants will be divided into two groups: standard (nursing intervention) and experimental (nursing intervention and OMT). A neuro-urologist will determine the eligibility for the study. The outcomes will include self-reported and instrumental measures that will be evaluated in 3 times (before, at the end of the intervention and the follow- up three months). The protocol has been approved by the Ethics Committee of the Città della Salute e della Scienza Hospital of Torino on 15.04.2019, protocol number 0040534. The standard intervention has been scheduled for 28.10.2019.
