Active clinical trials for "Dysbiosis"

Olfactory dysfunction is frequent in Parkinson Disease (PD) and may be present years before the motor symptoms appear. The early olfactory dysfunction could result from environmental factors acting through the nasal cavity such as microbial communities. In across-sectional bicentric study, groups of 160 PD patients and 160 controls will be compared for nasal microbiota composition according to their geographical origin. We will search an association between microbiota and the presence of an olfactory deficit, cognitive deficit and thymic disorder.

African Americans have the greatest burden of endothelial dysfunction and hypertension. Recently, gut microbial dysbiosis (a term that describes a poorly diverse gut microbial profile and lower short-chain fatty acid (SCFA) production) has been linked to hypertension and may be involved in the pathogenesis of hypertension in African Americans. African Americans have been reported to have lower gut SCFA and SCFA can reduce blood pressure. Exercise reduces blood pressure and improves gut dysbiosis (increases SCFA) and likely couples' improvements in gut microbial health and vascular function to reduce blood pressure. Thus, the goals of this research are to fill a critical void concerning the interaction of gut dysbiosis, hypertension, and utilizing exercise to identify gut microbial adaptations that accompany a reduction in blood pressure. The short-term implications of this work will advance the clinical communities understanding of the relationship between dysbiosis and the pathogenesis of hypertension in African Americans, while long term implications will promote identifying adaptable gut microbes associated with vascular health to aid in amending treatment strategies for hypertension.

To evaluate the effects on microbiota composition after the administration of an oral supplementation based on Alpha-lactalbumin in subjects with dysbiosis.

Dysbiosis is a situation in which the normal function of an ecological net is altered. In health there is a cross talk between the host and the microbiota in order to maintain and promote a state of eubiosis. In dysbiosis a state of inflammation, a loss of hydration, a change in pH, a loss of the barrier function are all allies of key pathogens that work against the host. Stop dysbiosis is a bigger multibranch project focussed on different aspects of clinical dysbiosis including this prospective interventional double blind randomised clinical trial. Stop dysbiosis comprises further clinical studies in several areas such as oral dysbiosis, skin dysbiosis, vaginal dysbiosis and cancer dysbiosis, between others. One of the most common dysbiosis of the mouth is periodontal and mucosa dysbiosis that courses with inflammation of the gingiva (gingivitis). This inflammation induces some enzymes that in a later stage destroy connective tissue. The current study beeing presented now is focussed to research the effect of a composition with Saliactive ® topically delivered to the oral cavity vehiculized in an everyday toothpaste (YOTUEL® microbiome toothpaste) in a group of patients with oral dysbiosis.

This randomized control trial study among Pre-exposure prophylactic users (PrEP) aims to learn and determine the efficacy of Screening, brief intervention, and referral to treatment (SBRIT) in reducing the risk of alcohol use. The main questions it aims to answer are: How alcohol use impacts the PrEP continuum and to understand how early intervention and treatment approach affects alcohol use and PrEP adherence. Investigate the effectiveness of the SBIRT intervention in preventing hazardous alcohol use and its impact on gut dysbiosis in PrEP users. To determine alterations in the gut microbiome (dysbiosis), intestinal homeostasis, systemic inflammation, and markers of liver disease associated with hazardous alcohol use among PrEP users.

In this randomized controlled study, preventive intervention of aspirin combined with probiotics or aspirin combined with placebo would given to PE (pre-eclampsia) high-risk population with gut microbiota dysbiosis during their pregnancy, and finally assess the efficacy and safety of aspirin combined with probiotics to prevent PE.

This is an observational cross-sectional study whose objective is to analyse associations between the intestinal and salivate microbiota with lifestyles (eating patterns, physical activity, tobacco and alcohol consumption), arterial aging and cognitive function. It will take place in five different research units located in Spain

Study Description The goal of this observational study is to detect intestinal flora and the metabolic products in premature infants diagnosed as necrotizing enterocolitis. The main questions it aims to answer are: 1. Whether there is intestinal flora in the stool of premature infants. 2. Are there dysregulated intestinal flora and their metabolic products in premature infants diagnosed as necrotizing enterocolitis. 3. The detailed role and underlying mechanism of the intestinal dysbacteriosis and the metabolic products in premature infants diagnosed as necrotizing enterocolitis. Participants, premature infants diagnosed as necrotizing enterocolitis (NEC group), will be asked to collect stool (usually 2 times) for intestinal flora analysis. If there is a comparison group: Researchers will compare premature infants without necrotizing enterocolitis (control group) to see if their intestinal flora and the metabolic products also changed as their NEC counterparts.

The goal of this observational study is to contribute to a better understanding of the perioperative kinetics of intestinal microbial composition and association with surgical site infections. The main question this study aims to determine if: Patients undergoing surgery develop transient intestinal dysbiosis Such transient dysbiosis is associated with translocation to the systemic circulation and surgical site infection Patients undergoing elective abdominal surgery will be included prospectively. Informed consent will be obtained. From patients the following information and samples will be collected: Perioperative: Baseline health data, nutrition data, measurement body composition, glucose monitoring Intraoperatively: Mucosal swabs Blood from central venous catheter and portal vein Mesenteric lymph node Intestinal specimen Subcutaneous biopsy Postoperatively: If a surgical site infection occurs samples from infected site

The performance of the microbiota is observed in all clinical and pathological stages of carcinogenesis, since its development, diagnosis and treatment, including prognosis and survival. However, it was found that there is a scarcity of studies on biliary microbiota and its relationship with hepatobiliopancreatic diseases. Therefore, further investigation is necessary, since reaching the biliary microbiota may suggest ways for studies of biomarkers, diagnoses, tests and therapies in hepatobiliopancreatic diseases. For this, bile samples will be collected in cases and controls patients to characterize the microbiota and its variations according to the disease.
