Filter by:Ulcerative colitis(UC) is one of the two main forms of inflammatory bowel disease(IBD), which seriously affects the quality of life of patients. Previous studies have demonstrated that more than 60% of IBD patients have sleep disorders, which is emerging as an important risk factor for disease recurrence and poor prognosis. However, the mechanisms by which sleep disorders regulates the occurrence and development of IBD remain undefined. This study aims to explore the clinical characteristics of ulcerative colitis patients with sleep disorders based on the microbiota-gut-brain axis, to analyze the effects of sleep disorders on autonomic nervous function, gut microbiota, and metabolites in UC patients.
This study is a randomized, double-blind, placebo-controlled study of N=120 apparently healthy men and women. The purpose of this study is to assess the effect of a novel dietary supplement on blood markers of nutrient status, gut microbiome, and overall quality of life.
The goal of this pilot study is to examine the feasibility and effects of an 18-month intervention diet compared to an active control diet (standard diet) in those living with Parkinson's Disease (PD), without dementia. Research has shown that eating components of Mediterranean diets are associated with a 30% lower risk to develop PD and a 40% lower mortality rate in those living with PD. Diet may influence the gut and microbiomes, thus may affect PD risk and progression. This study will examine how easy it will be to adhere to a certain type of diet for 18 months and what changes may occur in the gut microbiome and in PD symptoms on a specific diet during that time. The study will involve in-person study visits at UBC as well as online diet coaching sessions and online group cooking classes over Zoom. This is a randomized study, meaning that participants will be assigned by chance to either the Mediterranean-style diet group or the standard diet group for the duration of the 18 months. This pilot study will also examine recruitment rates and retention, in order to prepare for a larger future study.
Myrkl is advertised as a dietary supplement for use before alcohol consumption that is effective in prevention of side effects during the next day. With this research, the investigators want to determine the impact of the mentioned dietary supplement on the intestinal microbiome. For this purpose, the research was designed in three phases before, during and after the research as a double blind trial. In doing so, the subjects take a stool sample before and after the intervention and during the intervention, fill out questionnaires and undergo cognitive tests. At the same time, they give a blood sample after the intervention. After the results of the analysis are due, the researchers enter the data into the for that the predicted Access table (rel. representation of genera/genera/species, average results by questionnaires). The entered data is processed as part of statistical analysis.
Calcific aortic stenosis (CAS) is a disease characterized by progressive calcification of the aortic valve, obstructing the passage of blood from the left ventricle into the general circulation. It is the most frequent cause of valve disease in the elderly. To date, no means of preventing the disease has been discovered, and the only treatment available is valve replacement during cardiac surgery, or percutaneous implantation of a valve prosthesis when the narrowing becomes severe and causes symptoms. The intestinal flora or microbiota, the reservoir of all the microorganisms in the gut, is implicated in numerous diseases, particularly of the intestine. But to date, no study has established a link between CAS and microbiota. The intestinal microbiota acts through molecules produced by itself or the host and passing into the bloodstream. In the pathophysiology of CAS, the valve leaflets are breached and do not heal. These molecules can enter and have beneficial or deleterious effects, in particular promoting calcification of aortic valve cells. Concrete objectives: Improve understanding of calcific aortic stenosis in humans Study the composition of intestinal flora in patients with aortic stenosis and compare it with healthy subjects Study the molecules in the intestinal flora likely to be involved in the development of aortic stenosis in humans.
This survey is designed to investigate the effect of highland barley β-glucan supplementation on the regulatory of blood pressure, gut microbiota and cardiovascular risk fators in subjects with hypertention.
Many previous studies had revealed that gastrointestinal microbiome is changed compositionally and ecologically in patients with colorectal cancer comparing with healthy population. These finding provide us with a new sight to take advantage of gut microbiota. The current study aims to explore new potential biomarkers for early screening and prognostic prediction of colorectal cancer and colorectal polyps by analyzing metagenomics and metabolomics of gut microbiota.
The MA-PPING is a multicenter prospective observational study that includes patients undergoing surgery for gastrointestinal cancer. The study aims to map the oral and gut microbiome of patients diagnosed with pancreatic, esophageal or colorectal cancer during their surgical patient journey from the moment of diagnosis until full recovery (three months after surgery).
