NCT ID: NCT05804851 Active, not recruiting - Skin Microbiome Clinical Trials

Skin Microbiome of Chinese Population Cohort Study

Start date: May 8, 2023
Study type: Observational [Patient Registry]

This observational study aims to investigate the relationship between public health and the skin microbiome in the province of Zhejiang. Due to the lack of current research on the skin microbiome, the following general questions will be investigated in this study: 1) What connection exists between dietary practices and facial skin microbiome? 2) How do people's lifestyle routines affect the facial skin microbiome? 3) What effects does the altered living environment have on people's facial skin microbiomes? 4) How do the seasons affect people's facial skin microbiomes? Every 3 to 4 months, the participants' facial skin microbiota samples will be taken, and they will be asked to complete a survey.

Start date: October 30, 2022
Study type: Observational

This clinical study will evaluate the clinical performance and the safety of the CE-marked casting and padding materials when used in routine fracture care without any additional invasive methods and within the intended use. As primary objective the cast therapy´s influence on skin microbiome during fracture management will be investigated. Further, the influence of the padding material on the skin microbiome, device comfort, skin conditions, and impact on daily life activities as well as HCP´s and patient´s satisfaction and general product safety and performance are considered as secondary outcomes.

NCT ID: NCT05032768 Recruiting - Breast Cancer Clinical Trials

The Association Between Radiation Dermatitis and Skin Microbiome in Breast Cancer Patients

Start date: January 1, 2021
Study type: Observational

The breast cancer patients who received radiotherapy after mastectomy and breast reconstruction will be enrolled. The skin microbiome before radiotherapy and its changes after radiotherapy will be analyzed systematically to find out whether the skin microbiome is associated with the severity of radiation dermatitis.

NCT ID: NCT04759924 Completed - Skin Microbiome Clinical Trials

Mother - Newborn Observational Study

Start date: March 1, 2021
Study type: Observational

Pregnancy leads to a number of skin changes but empirical evidence about the structural and functional changes of the skin is scarce. Findings on skin structure and function in newborns and children in the first year of life reveal a rapid skin maturation after birth, but evidence indicates, that in particular water-holding and transport mechanisms are very different to adults in the first year in life. The most important open question is whether and how the maternal cutaneous properties predict the skin function of their children. This is especially relevant for the skin microbiome, because it closely interacts with the host and is assumed to play a role in many skin diseases. Therefore, the objective of this study is the description of characteristics of skin and hair structure and skin function of pregnant women and their newborns during pregnancy and for both in the first six months after delivery. In addition, we investigate associations of the mother's and their newborns skin microbiomes, and changes thereof in the newborns within the first six months of life. The study has a descriptive, exploratory, longitudinal design. We will recruit pregnant females between 18 to 45 years old using advertisement campaigns, study information material in the waiting areas of their gynecologists, in pregnancy preparation services and in hospital's outpatient services. If they are interested and fulfill the inclusion criteria, they are invited to participate. Taking into account an assumed dropout rate of about 30%, a final sample of n = 100 women is expected. A detailed dermatological examination and general medical condition are documented. Non-invasive, standardized skin and hair physiological and skin microbiome measurements are performed during the visits. Baseline is scheduled during pregnancy until late 4 weeks before delivery. Follow-up visits are scheduled 4 weeks and 6 months after birth for mothers and newborns. Descriptive statistical methods will be calculated for frequencies and associations over time depending on scale levels of the measurements. In our longitudinal study, we will characterize a broad range of individual and environmental characteristics of mothers and their newborns to evaluate interrelationships with skin parameters and their changes over the period of at least 8 months. Considering these multiple variables and levels together will allow a deeper understanding of the complex interrelationship of the newborns skin maturation.

NCT ID: NCT04319536 Recruiting - Vaginal Microbiome Clinical Trials

Integrated Genetic and Functional Analysis of the Female Microbiome in a Flemish Cohort

Start date: March 1, 2020
Study type: Observational

The aim of the project is to improve our knowledge on the stability and temporal dynamics of the Flemish female microbiome (vagina, skin and saliva) in relation to different lifestyle factors and environmental conditions and to establish certain individual and social risk factors that can influence the healthy microbiome. Therefore, microbial DNA from swabs will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the microbial species present in these samples. Special attention will go to microbial species that are overrepresented in the healthy populations as potential health promoting microbes (i.e. probiotics).

NCT ID: NCT04231500 Recruiting - Clinical trials for Graft Versus Host Disease

The Skin Microbiome in Graft Versus Host Disease

Start date: March 1, 2023
Study type: Observational

Based on the evidence on the impact of the intestinal microbiome on the Graft Versus Host Disease (GVHD) after allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT), it is hypothesized that the skin-microbiome may play a role in cutaneous GVHD as well. Therefore, this study aims at investigating the skin-microbiota of patients with GVHD after allo-HSCT and of patients without GVHD after allo-HSCT.

NCT ID: NCT03605108 Completed - Gut Microbiome Clinical Trials

The Influence of Oral Probiotics on the Microbiome and Lipidome

Start date: June 29, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to measure oil production of the face, facial properties, and gut bacteria in people being given oral probiotics. Probiotic supplements contain active cultures of bacteria that are thought to be beneficial to human health.The investigators want to find out if probiotics taken by mouth alter the bacteria in subject's gut and subject's skin oil production compared to a placebo. This is a single blind study and subject may receive a probiotic or a placebo for the first half of the study and a placebo or a probiotic for the second half of the study. Subject will not know what was given to participants.

NCT ID: NCT01942577 Withdrawn - Skin Microbiome Clinical Trials

Microbiome Survey of Preterm Infants

Start date: September 2013
Phase: N/A
Study type: Interventional

The skin and intestinal tracts of humans are covered with microbes, and the gene products of these microbes are collectively known as the human microbiome. Many studies in recent years have linked the microbiome to many aspects of human health and disease. Premature infants are vulnerable to invasive infections, some of which may originate from the microbes that colonize the skin and in the intestinal tract. Therefore, determining the patterns of early life colonization and the sources of colonization in these infants may be critical to determining infectious risks. This prospective study is proposed to identify the sources of microbes that colonize extremely low birth weight (ELBW; <1000 g birth weight) infants immediately following birth through the first month of life. The study team plans to non-invasively survey the skin and stool of ELBW preterm infants in combination with sampling of their mothers' skin and stool and the intensive care nursery (ICN) environment. As controls, the study team will perform a similar survey of full term mother-infant pairs. Samples will be analyzed using high throughput sequencing techniques to determine microbial content. Topical barrier sprays or emollients are commonly used early in life in the ELBW infant to reduce insensible water loss and enhance the integrity of the skin barrier. The effect of these treatments on the development of the skin microbiome remains unknown. As part of this study, the study team also proposes the application of two different skin barrier therapies to small areas on infant's legs to determine the effects of the different treatments on skin colonization. While all parts of the study are described in this summary and the detailed description, the remainder of the record focuses on this interventional portion of the study (Group 2). The goals of this study are outlined as follows: 1. To elucidate the relationship between microbes in the health care environment and colonization patterns of the intestinal tracts in preterm and term infants. 2. To understand the relationship between mode of delivery, the health care environment, and the colonization of the skin in preterm and term infants. 3. To determine the effects of topical skin barrier therapies on the colonization patterns of the skin in preterm infants. 4. To ascertain the relationship between the composition of the microbes colonizing preterm and term infants and the development of mucosal and systemic immunity to those microbes.
