In the investigators study, the investigators will focus on the screening of the related proteins and miRNA to IBS in order to reveal the possible clues or molecular mechanism for this disorder.
The purpose of this study is to evaluate the effect of regular consumption of probiotic milk in preventing illnesses in Finnish children attending day care centres, and possible cost-benefits that could be associated with fewer illnesses.
The primary objective of this study is to assess the overall survival (OS) of oral linifanib given as monotherapy once daily (QD) compared to sorafenib given twice daily (BID) per standard of care in subjects with advanced or metastatic HCC.
Irritable Bowel Syndrome (IBS) is a common condition characterised by abdominal pain or discomfort and altered bowel habit affecting up to 10% of the population. There are several groups of patients that are based on differing bowel patterns including IBS with diarrhea (IBS-D) and those with post infective IBS (PI-IBS) whose symptoms begin after an acute infection. Saccharomyces cerevisiae, the yeast used in bread making has been shown to reduce the duration of infectious diarrhoea. Part of the benefit maybe that it can destroy bacterial toxins. Recent studies suggest an increase in proteases (chemicals which breakdown proteins) in the stool of patients with IBS-D. The investigators think that this yeast may benefit patients with IBS-D and PI-IBS by reducing the amount of protease in stool. This is important because proteases have been shown to be potentially important in generating some of the discomfort experienced by patients. The investigators will study patients with chronic IBS-D who will receive 2 weeks treatment with the yeast or placebo followed by a 4 week gap and then a further 2 week treatment with placebo or the yeast, with the treatments allocated randomly. The investigators will also study 30 subjects who still have persistent loose bowel function 6 weeks after an infection with Campylobacter jejuni, one of the commonest causes of gastroenteritis in the UK. Subjects will be randomised to take either the yeast or placebo for 4 weeks . In both studies, the investigators will examine the effect of treatment on stool proteases, stool frequency and consistency and abdominal discomfort; the investigators will also take blood samples to examine some aspects of immune system function. The results of the study may suggest how yeast provides a benefit in patients with IBS and diarrhea and will provide data for a larger clinical trial.
The investigators' believe that it is important to medical practice to obtain information on how expandable metal stents work in a large group of patients who have metal stents placed in the gastrointestinal system. The purpose of this research study is to collect information on the stent placement in our facility and how the patients responded to the stent placement.
Introduction: The primary function of the gastrointestinal (GI) wall is digestion and absorption of nutrients that are important for growth and development. The second important function of the GI wall is forming an effective barrier to prevent penetration of potentially harmful components from the inside of the gut (lumen), via the GI wall, into the body. A compromised barrier function may play an important role in the development of a range of inflammatory GI diseases such as coeliac disease, Inflammatory Bowel Disease (IBD), food allergy, but also in the pathophysiology of postoperative complications. It is important and clinically relevant to have reliable GI permeability tests, however the existing test leave room for improvement. Rationale/aim: Three new tests are developed to assess gastrointestinal permeability in both normal controls with and without raised permeability, and in patients with coeliac disease. In the current study these new permeability tests will be evaluated and compared with the golden standard permeability test, the dual sugar test.
The purpose of this study is to determine whether Omegaven is effective in the treatment of parenteral nutrition associated liver disease (PNALD).
This study is being conducted to compare surgical and patient outcomes across stapled (Group II) versus hand-sutured (Group I) groups.
The goal of this clinical research study is to use a new breathing test that measures the amount of nitric oxide (NO) you exhale. Researchers want to compare your "NO" levels to the amount of inflammation in your lungs, as measured using a positron emission tomography (PET) scan reading, and with respiratory symptoms questionnaire.
