Filter by:The aim of this multicenter, prospective, randomized, double-blind and large sample study is to explore the preventive effect of low-dose droperidol on POD in elderly patients after non-cardiac surgery, providing new approach for reducing the incidence of POD and improving the prognosis and quality of life.
The aim of the study is to confirm the association between hypermobile Ehlers Danlos syndrome (hEDS) and mast cell activation syndrome (MCAS) in patients with digestive disorders managed in allergology departments.
Fructose is increasingly present in our food. The increase in its consumption is associated with the increase in the prevalence of several pathologies such as metabolic syndrome or hepatic steatosis. The effect of fructose consumption on brain health has been poorly studied. Studies in animal models show that diets enriched in fructose promote the development of emotional behavior disorders. Fructose malabsorption is also associated with changes in the microbiota that could also impact brain health. However, no human study to date has associated fructose malabsorption with changes in the gut microbiota and effects on brain health. The objective of this study is to study the emotional behavior of a population of healthy volunteers according to the presence or not of fructose malabsorption. Patients with fructose malabsorption are susceptible to gut dysbiosis without necessarily consuming high amounts of fructose.
The purpose of this project is to study the the efficacy and safety of probiotics implantation through infusion during colonoscopy in the treatment of functional constipation and irritable bowel syndrome. The study is a single-center, prospective, randomized, single-blind, controlled, cohort study. The invesitigators plan to enroll 80 patients with functional constipation and 80 patients with irritable bowel syndrome. The invesitigators will randomize the included study subjects. The experimental group receive basic treatment and a single infusion of probiotics through colonoscopy. The control group receive basic treatment and a single injection of normal saline through colonoscopy. The invesitigators will follow up the patients for 8-12 weeks. The primary endpoint is the efficacy of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. The secondary endpoint is the safety of the single colonoscopic probiotics infusion in functional constipation and irritable bowel syndrome patients. Other exploratory objectives include the alterations in clinical indicators, fecal microbiota, and intestinal microbiota metabolites in feces and serum.
Currently, the question remains whether palliative primary tumor resection could improve overall survival of minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases. The aim of this study is to determine if there is an improvement in overall survival of palliative primary tumor resection followed by chemotherapy in minimally symptomatic patients with colorectal cancer and synchronous unresectable metastases compared to those of upfront chemotherapy/radiotherapy alone.
Over the last decade, the use of mini-organ or organoids has been increasingly developed in fundamental research. Indeed, digestive organoids represent an essential advance compared to classical culture systems (epithelial cell lines, immortalized cells) since they preserve in culture the functional complexity present in vivo (architecture, different cell types). They also have the advantage of being able to be propagated indefinitely (unlike explants), minimizing the use of animal models and reducing the amount of tissue required. Finally, their growth and development depends on the origin of the sample (the organoid will develop differently if the cell source comes from a patient suffering from an inflammatory bowel disease, for example), thus generating models of human pathologies to better determine their physiopathology. The use of organoids in biomedical research has proven to be an indispensable tool for the understanding of cellular and molecular mechanisms involved in epithelial renewal and the screening of molecules and ingredients for applications in the health and agri-food sectors.
Frailty is a common clinical syndrome in older adults that may carry an increased risk for poor health outcomes including falls, hospitalisation, and mortality. Having a colonoscopy can be associated with potential adverse outcomes in frail patients. At present, however, frailty is not routinely assessed in gastroenterological clinical practice. In a prospective randomised controlled study consenting patients over 65 years at the Princess Alexandra Hospital will receive either a) personalised (tailored) approach that includes assessment of frailty and structured information provided to the consumer or b) current standard practice in regards to having a surveillance colonoscopy to determine the effects on patient satisfaction and percentage of colonoscopies avoided.
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.
Patients with high clinical suspicion of hepatobiliary malignancies should undergo PET/CT examination with two imaging agents, 68Ga-FAPI (fibroblast activation protein inhibitor) and 18F-FDG within one week, and collect tumor tissue. Finally, the PET/CT results were compared with the pathology report to evaluate the role of 68Ga-FAPI PET/CT imaging in the diagnosis of hepatobiliary malignancies
Globally, cirrhosis and liver cancer carries a huge burden and accounts for about 3.5% (2 million) of all deaths every year. Once decompensated, i.e. development of ascites, variceal bleed, encephalopathy, and jaundice, the life expectancy is markedly reduced to a median of two years. The definitive treatment in this stage, i.e., liver transplantation is limited by cost, lack of donors, and life-long immunosuppression. In addition to complications due to portal hypertension and hepatic insufficiency, decompensated cirrhosis is associated with malnutrition, sarcopenia, immune dysfunction, and impaired regeneration. Patients with cirrhosis are growth hormone (GH) resistant, with reduced insulin-like growth factor, which are linked to malnutrition and poor liver regeneration in cirrhosis. Diverse preclinical and clinical investigations in vitro and in vivo, have shown a benefit of GH in GH deficient, elderly and HIV positive patients. GH therapy in cirrhosis has been shown to improve nitrogen economy and to improve the GH resistance in a small pilot study by Donaghy et al. Also, GH therapy of short duration has shown to increase IGF1 levels, IGFBP-3 levels in patients of cirrhosis. GH therapy has also been shown to improve liver regeneration and protein synthesis after hepatectomy in patients of HCC with cirrhosis. However, there is a scarcity of data on clinical impact of long term administration of GH therapy in patients of cirrhosis. Hence, we undertook the present study to study the effect of growth hormone on clinical outcomes, malnutrition, immune cells and liver regeneration in patients with cirrhosis.
