NCT ID: NCT06325358 Not yet recruiting - Clinical trials for Multiple Sclerosis, Relapsing-Remitting

the EXPOSITION Study

EXPOSITION
Start date: April 15, 2024
Phase:
Study type: Observational

This is a cross-sectional study to evaluate the variation of biological biomarkers of oxidative stress and inflammation in response to the external exposome, in people with Multiple Sclerosis (pwMS).The objective is to study the variation of biological biomarkers of oxidative stress and inflammation in response to external exposome in pwMS, controlling for other biomarkers (cytokine, neurofilaments, microbiome), gender, age, anthropometric measurements, vitamin D levels and medical history. Specifically, the variation of microRNAs is defined as the primary outcome, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome. Following the functional exposome approach:(1)Information on a pwMS sample about socio-demographic characteristics and medical history will be collected and specific components of the (2) On the same pwMS sample, the internal exposome variation will be measured. MicroRNA levels and gut and nasal microbiota alpha- and beta-diversity and relative bacterial abundances will be considered as biomarkers of oxidative stress and inflammation. At the same time, cytokines and neurofilament proteins (NfL) will be measured as biomarkers of neurodegeneration and axonal damage. Adults (≥ 18 years) pwMS, with relapsing-remitting course, diagnosis of MS according to 2017 McDonald criteria and residing in Pavia or Milan (Italy) will be included. Potentially eligible pwMS will be screened by a neurologist expert in MS who will verify that all the inclusion criteria will be fulfilled. To validate variation among 7 selected MS diagnostic miRNA, in response to urban air pollution, urbanization, lifestyle and quality of life components of the external exposome, the differential expression (ΔCT) for each miRNA will be considered as the outcome measure. Two hundred eligible pwMS who meet the inclusion criteria and sign the informed consent will be included in the study, to consider 15% dropout at the blood sampling stage.

Developmental Impacts of Microplastics Exposure in Early Life

DIMPLE
Start date: October 1, 2023
Phase:
Study type: Observational

The goal of this observational study is to characterize and evaluate micro- and nano-plastic (MNP) exposures among mothers and infants in mother-infant dyads one-month postpartum living in Denver and Boulder, Colorado. The main questions it aims to answer are: - What MNPs are present in breastmilk and maternal blood samples and in their infants stool sample? - Are there associations between amount of maternal MNPs in breast milk and mass of MNP particles in infant stool? - Which environmental and lifestyle factors are most predictive of maternal MNP burden? - Is infant exposure to MNPs associated with birth weight and postnatal growth trajectories? Participants will: - Complete several questionnaires assessing medical histories, lifestyle factors, environmental exposures, eating behaviors, etc. - Provide biological specimens including: maternal blood, stool, and breastmilk; infant stool - Clinical visit to have anthropometric measures documented including maternal height and weight, infant weight, length, and skin-fold thickness

NCT ID: NCT06083415 Recruiting - Clinical trials for Environmental Exposure

Early Breast Growth in Girls Aged 6 to 8 Years in the Current Environmental Context

PENELOPE
Start date: May 15, 2023
Phase: N/A
Study type: Interventional

Various studies show an increase in the number of cases of early puberty in girls with breast development with a variable clinical presentation and evolution. This increasing phenomenon concerns girls between 6 and 8 years old. In a large number of cases, from 70 to 95% depending on the series, no medical cause is found and environmental factors are suspected to be involved. Descriptive studies of these patients are scarce and not always provide an overview of all the parameters in line with the concept of the exposome. The PENELOPE clinical trial will allow to analyze a large number of parameters, including the adipose tissue, its metabolism, the endocrine disruptors, and the epigenetic modifications, and to study the impact of environmental health measures in the evolution of these parameters. The data from the analyses of the endocrine disruptors of the patients will be explored in parallel in experimental models (amphibians, murine, cellular) in order to test potential mechanistic hypotheses.

Personalized Mobile Intervention to Reduce Exposure to Endocrine Disrupting Chemicals in Adults of Child-Bearing Age

Start date: May 1, 2022
Phase: N/A
Study type: Interventional

The goal of this intervention study is to determine to what extent the Million Marker (MM) program reduces users' endocrine disruption chemical (EDC) exposure levels and changes their environmental health awareness and behaviors. The main questions it aims to answer are: - Can the investigators see a reduction in EDC levels in participants' urine samples after using the MM Detect and Detox kit? - Can the investigators see a change in participants' environmental health literacy, knowledge, and behaviors after using MM's products and services? - How can Million Marker improve their app and platform to improve the user experience? Participants will collect their urine pre- and post-intervention, and will take a comprehensive exposure survey (via the MM app) before sending back their samples. This exposure survey will ask about participant's product use, diet, and lifestyle behaviors. Participants will also fill out surveys pre- and post-intervention assessing their perception of environmental health, as well as usability of the platform.
