Filter by:The primary aim of this study is to evaluate the impact of introducing a new enteral tube feed on health and feeding related quality of life. Secondary aims are to assess ease of use, liking, compliance, gastrointestinal tolerance, nutrient intake, anthropometric changes and safety.
The primary aim of this study is to assess (in healthy volunteers) the rate at which a glucose drink leaves the stomach by sequential magnetic resonance imaging (MRI) of the stomach contents using a 0.5 tesla upright MRI scanner, and comparing with the rate derived from a standard method which uses a stable isotope tracer and breath testing. The main question it aims to answer are: - Do MRI derived images of stomach contents at low magnetic field (0.5 Tesla) have sufficient resolution to provide a reproducible assessment of gastric emptying - What is the agreement and relationship between the rate of gastric emptying determined from the 2 methods Participants will be asked to attend the imaging centre on one occasion in the morning after fasting from midnight and to sit within an upright MRI scanner for a period of approximately 140 minutes. Images of their stomach will be taken before and for 2 hours after consuming a drink containing glucose and a small amount of sodium acetate which contains a heavier form of carbon. Before each image is taken, participants will be asked to exhale into a 500ml bag to collect a breath sample.
Polydextrose (PDX) (8-30g/day) has been reported to increase faecal bulk and consistency, leading to easier stool passage in healthy subjects. Studies on its effect on defaecation frequency and colonic transit time have provided mixed results. The primary objective was to investigate the effect of PDX consumption by mildly constipated subjects on faecal bulk, measured as total faecal wet weight of 4-day collections. Secondary outcomes (faecal dry weight, defaecation frequency, stool consistency, ease of stool passage, total colonic transit time and gastrointestinal symptoms) were also explored. 51 subjects participated in a 4-week, two-center, randomized, double-blind, placebo-controlled, parallel study testing a control (CON) and a PDX treatment (18 g/d included in biscuits and drink mixtures)
Acute gastrointestinal injury (AGI) is related to poor outcomes of critically ill patients [1] through many underlying mechanisms [2]. It is also a part of the process of multiple organ dysfunction syndrome (MODS). However, the morbidity of acute gastrointestinal dysfunction in critically ill patients is highly underestimated due to the scarcity of accurate measurement and thus the causes are still unclear. In this study, investigators are going to apply the technique of point-of-care ultrasound (POCUS) evaluation on the bowel diameters, wall thickness and movement combined with intra-abdominal pressure to determine the occurrence of AGI. The superior mesenteric artery (SMA) blood flow is also evaluated by POCUS to find out the association between SMA blood flow and AGI.
This study aims to test the central hypothesis that adding to the diet daily yogurt provides beneficial effects on digestive health and subjective mood in healthy adults.
The objective of the current study is to evaluate the effect of whole cell fermentate on gut health, including GI system function, such as supporting consistency and regularity of bowel habits, as well as changes in microbiota. The role of the GI system can also be extended to immune regulation because approximately 70% of the entire immune system in the body is located around the gut. Thus, the health and wellbeing of the gut can have a great impact on whole-body health. Therefore, this study will assess the effect on overall immune function.
The aim of this randomised, placebo-controlled, 3-way blinded study was to determine the effect on GIS symptoms, pain and anxiety of acupressure applied for a total of 12 mins, as 3 mins at each of the ST25, CV12, TH6 and HT7 acupuncture points, at 0, 4 and 8 hours after laparoscopic cholecystectomy operation. The research data were collected using a patient data collection form, the Numeric Pain Intensity Scale and the State-Trait Anxiety Inventory. The patients were evaluated in respect of the time to first flatus and defecation, pain and the State-Trait Anxiety points at 0, 4, and 8 hours postoperatively.
The purpose of this online research study is to determine whether or not a gradual caffeine reduction program developed at Johns Hopkins can help people reduce their caffeine use. The investigators will provide materials to help guide caffeine reduction and ask questions to track caffeine use over several weeks. The investigators will also assess how reducing caffeine may benefit common caffeine-related problems such as anxiety, sleep disturbances, and gastrointestinal distress. The study will also determine whether or not people like participating in this caffeine reduction program in an online format.
The objective of the study is to measure the evolution of the quality of life in infants between 0 and 5 months old, not breastfed and suffering from regurgitation or colic.
This study aims to test the central hypothesis that adding to the diet daily yogurt with honey provides beneficial effects on digestive health and subjective mood in healthy adults.
