Filter by:The goal of this clinical trial is to understand varying in responses to different dietary patterns in healthy people who are getting a health screening colonoscopy. The main questions it aims to answer are: - What is the variability in the change of the microbes in the gut of (1) a provided diet that is high in fiber vs (2) a diet of the participant's choice. - What is the magnitude of fasting changes in glucose and lipids following the short-term, high-fiber feeding period and identify candidate predictive factors (short-chain fatty acids, BMI, sex, starting glucose level) for these changes Participants will be in one of two groups: 1. High-fiber diet group: These participants will have a series of measurements that include: blood biochemistries, body composition measured via DEXA, anthropometrics, surveys and questionnaires, and collection of fecal samples. 2. Normal diet group: These participants will eat a diet that is of their choosing (ad libitum) and will have a series of measurements that include: fecal samples, and questionnaires/surveys including food records.
The goal of this clinical trial is to evaluate the feasibility of remote time-restricted eating (TRE) and mindfulness-based stress reduction (MBSR) interventions and the preliminary effect on EOCRC-related markers. The main question[s] it aims to answer are: - Is it feasible and acceptable to conduct 8-week remote interventions of TRE, MBSR, and combined TRE+MBSR among young adults with excess adiposity and moderate-to-severe perceived stress? - Will participants in the combined group lose more body weight and reduce their stress levels than those in the remaining groups? - Will participants in the combined group experience better body composition changes and improve their cardiometabolic health compared to those in the remaining groups? - Will participants in the combined group exhibit changes in the microbiome compared to those in the remaining groups? Participants will: - Complete 8 weeks of a TRE intervention - Complete 8 weeks of a remote MBSR intervention Researchers will compare 1. TRE alone; 2. MBSR alone; 3. TRE + MBSR; and 4. Control to see if the study is feasible and acceptable; to see if individuals lose body weight; to see if individual stress levels reduce; to see changes in the microbiome.
Babies and children have an increased risk of getting an infection with a bacteria in the bloodstream (sepsis). It is often difficult for the doctor to determine whether a child has an infection of the bloodstream, because the symptoms are often unclear and can also occur in children who are not sick. To determine whether there is an infection, a little blood is currently taken for a blood test (the blood culture) to investigate whether there is a bacteria in the blood. However, it often takes at least 36 hours before the results of this blood culture are available. That is why antibiotics are usually started immediately to treat the possible infection. However, it often turns out that the blood culture is negative after 36 hours, which means that no bacteria have been found in the blood. Usually the antibiotics are then stopped because it turns out that there was no infection at all. There is currently no good test that can predict whether (newborn) children have an infection or not. That is why too many children are currently wrongly receiving antibiotics. These antibiotics can damage the healthy bacteria in the intestines. There are many billions of 'beneficial bacteria' in the intestine. These play an important role in the digestion of food and protect against external infections. Antibiotics aim to kill bacteria that cause inflammation or infection. Unfortunately, antibiotics also kill some of these beneficial bacteria. In addition, unnecessary use of antibiotics contributes to antibiotic resistance. The aim of this research is to investigate whether Molecular Culture, a PCR based test that can identify bacterial pathogens in bodily fluids within 4 hours, has greater accuracy than traditional culturing techniques for bacteria in blood. If proven, this could lead to faster identification or exclusion of sepsis in children.
Cardiogenic shock is associated with a high mortality. The microbiome is a double-edged sword which can convey protective and detrimental cardiovascular effects. The significance of the enteral micobiome on cardiovascular mortality of patients with cardiogenic shock is still not known. This study aims to provide a deeper understanding of the role of the enteral microbiome and microbiome dependent metabolites in mortality and disease progression of patients with cardiogenic shock.
This research is a clinical trial aimed at improving the gut microbiome of patients with Irritable Bowel Syndrome (IBS) through a temple stay experience. Participants in the study are expected to participate in a temple stay experience for a maximum of 8 days. During the temple stay experience, participants are required to fill out a daily symptom questionnaire related to irritable bowel syndrome and record their diet and bowel movements using a dedicated mobile application. Upon completion of the temple stay, participants will conduct an evaluation of personal satisfaction with the experience. Through this, the study aims to collect and analyze data related to the Templestay experience with the goal of improving the gut microbiome of patients with IBS.
This is an 8 to14-week three-arm randomized controlled in children 8 to 12 years old. The main purpose of the study is to evaluate if stevia (as with other sweeteners and consistent with prior research in children and adults) has benefits for weight control and metabolic function relative to caloric sweeteners, and whether it provides benefits in this regard similar to water.
Prematurity remains the main cause of death and serious health problems in new-borns. Besides the need for hospitalization and medical interventions in the first weeks or months of the new-borns' life, prematurity can cause long-lasting health problems (e.g. multiple hospital admissions, developmental delay, learning difficulties, motor delay, hearing or eye problems, ...). Moreover, prematurity places an enormous economic burden on the society. Aside from the medical problems and the financial cost, the emotional stress and psychological impact on the parents, siblings and other family members should not be underestimated. Previous preterm delivery (before 37 weeks of pregnancy) increases the risk for recurrent preterm delivery in a subsequent pregnancy. Therefore, these women should be considered as 'high risk' for preterm birth. Infections ascending from the vagina may be an important cause of preterm delivery in certain cases. Some women have an abnormal vaginal microbiome and are therefore at risk for infections and preterm birth. On the other hand, the vaginal flora is more stable and resistant to infections in healthy pregnant women who deliver at term (after 37 weeks of gestation). Synbiotics are a mixture containing probiotics and prebiotics. Probiotics are living bacteria with potential beneficial effects that can be used safely in pregnancy, while prebiotics are consumed by the bacteria. It is known that probiotics, when used for a long period of time, can maintain a healthy and stable vaginal flora that may protect against infections. In this study, pregnant patients with a history of preterm birth will be included in the first trimester of pregnancy to start with synbiotics or placebo. The investigators will examine the effect of synbiotics on the vaginal flora and on the pregnancy duration. The hypothesis is that synbiotics, when started early in the pregnancy, can change the disturbed vaginal flora into a stable micro-environment.
There is strong observational evidence that sexual activity plays a key role in Bacterial Vaginosis (BV) acquisition and recurrence. Microbiological data support the contribution of sexual transmission to the pathogenesis of BV through the exchange of BV-associated bacteria (BVAB) between sexual partners. Although BV epidemiology strongly suggests sexual transmission, treatment of sexual partners is not recommended, based on prior treatment studies of male partners of women with recurrent BV, which showed no benefit with male treatment. Nevertheless, male condom use is highly protective against recurrent BV. This study aims to evaluate the male-partner's genital microbiome as a potential source of BV-recurrence in women undergoing vaginal microbiota transplantation (NCT04517487), and whether disinfection can eliminate BV-associated penile microbiome.
The primary objectives of this study are to evaluate the effect of early-life B. infantis Rosell®-33 supplementation in infants exposed to HIV on: - gut microbiome composition and diversity at 4 weeks of life - markers of intestinal inflammation and microbial translocation at 4 weeks of life - Th1 cytokine responses to BCG at 7 weeks and 36 weeks of life The secondary objectives include to evaluate the effect of B. infantis Rosell®-33 supplementation on: - longitudinal succession of the gut microbiota composition, diversity and function - relative and absolute abundance of B. infantis in infant stool during the first 36 weeks of life - stool metabolome - T cell subset ontogeny during the first 9 months of life. Exploratory objectives are to evaluate whether B. infantis Rosell®-33 supplementation improves: - infant growth - all-cause morbidity - neurodevelopment during the first 9 months of life - antibody responses to early childhood vaccines
