Filter by:The study will examine the potential efficacy and safety of two pre- and post-biotics on markers for gut inflammation and intestinal microbiota ecology in patients with Rett syndrome. Moreover, this trial will search for possible effects on epileptogenesis and quality of life.
This study aimed to examine the effects of using probiotic yogurt on body components (body weight, height, etc.) and digestive system (distention, gas, etc.) in obesity (obese women), which is an important public health problem all over the world.
The double-blinded placebo-controlled study compares the effect of fecal microbiota transplantation vs. Anaerobically Cultivated Human Intestinal Microbiota (ACHIM) or placebo (own feces) on manipulating the gut microbiota in patients with diarrhea-predominant irritable bowel syndrome (IBS).
To evaluate the effect of daily consumption of a combination of garlic and onion extracts on the intestinal microbiota and the production of short chain fatty acids in elderly healthy volunteers living in a residence. Likewise, any incident related to health that occurred during that period will be noted.
Periodontitis is a chronic inflammatory disease of the tooth supporting structures induced by a dysbiosis in the oral and subgingival microenvironment of susceptible patients. The long-term swallowing of high doses of periodontal pathogenic microorganisms could induce a dysbiosis of the intestinal microbiota, favouring the establishment of an 'inflamed' microbiome in terms of composition and/or function. The present project is aimed at a better understanding of the etiopathogenetic correlation between periodontitis and intestinal dysbiosis, and aims to explore the hypothesis that non-surgical periodontal treatment may reduce bacterial alpha diversity in stool samples. Fifty patients affected by stage III-IV periodontitis will be recruited, and treated by means of full-mouth scaling and root planing. Salivary and stool samples, together with a complete periodontal charting and a food diary will be collected and compared at baseline and 3 months after treatment. Age, gender and BMI-matched healthy individuals will be recruited as controls.
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
Vaginal dysbiosis is a common condition among women. Vaginal dysbiosis covers imbalances in the vaginal flora, caused by the composition of microbes, bacteria, viruses and fungi. Dysbiosis occurs in about 16% of all women in Denmark. A large proportion of women who have vaginal dysbiosis do not experience any symptoms. However, vaginal dysbiosis can present challenges in several contexts, including a higher tendency for bacterial infections in the female genitals, lower chances of pregnancy in women undergoing fertility treatment, just as it can predispose to premature birth. This project is aimed at women aged 18-40, who wants to participate in a study to investigate whether, by transplanting vaginal secretion from one woman with a normal vaginal bacterial flora to another woman with an imbalance in the vaginal bacterial flora (called vaginal dysbiosis), can establish a normal vaginal bacterial flora in the recipient of the transplant. The study will also explore weather genetic, immunological, hormonal, metabolic, health behaviors and clinical factors have significance on whether a normal vaginal flora is achieved after transplantation.
The gut microbiome is a complex ecosystem with a wide range of functions, and it is thought that it can influence multiple processes in the human body. In turn, the composition and activity of the gut microbiome is affected by many factors as well. Antibiotics can be very effective in treating bacterial infections, but they are also associated with detrimental health effects. Previous studies have already shown that antibiotics disturb the human gut microbiome composition by destroying commensal bacteria. As it is well known that the microbiome influences host metabolism, perturbation of the healthy microbiome (dysbiosis) is thought to be disease causing. Prebiotics, on the other hand, are beneficial for the gut microbiome. These so-called indigestible fibers are naturally present in our foods, but cannot be metabolised by the human body. Many bacteria in the human gut are able to ferment these fibers and they subsequently produce beneficial products for the rest of the body. Besides this, fiber intake stimulates growth of commensal bacteria in the human gut. Although it has become increasingly clear that prebiotics have a beneficial effect on the gut microbiome and general health, it is still unclear to which extent the beneficial effects of prebiotics supplementation occur after the gut microbiome is disturbed by antibiotics. We hypothesize that prebiotic supplementation after antibiotics use will improve restoration of the gut microbiome to a healthy state compared to placebo.
This is a study of the influence of skincare products containing chemicals such as parabens and phthalates on the skin microbiome.
This study will evaluate the incidence of allergic manifestations (the first of which is atopic dermatitis) and infectious diseases in children fed with an infant formula under real conditions of use.
