Brief Summary:

The purpose of this study is to identify metabolic signatures associated with malodor conditions. The investigators will perform state-of-the art metabolomics tests and bioinformatic data mining to explore if conditions leading to malodor can be screened by metabolomic profiling of urine samples.

Condition or disease
Nutritional and Metabolic Diseases

Detailed Description:

In this study, metabolite profiling analysis will be carried out on urine samples of individuals with malodor conditions related to metabolism inefficiencies. Metabolic profiles will be identified using the metabolomics equipment located in the NMR, HPLC and MS facilities of the Metabolomics Innovation Centre (TMIC). Multivariate statistical analyses will be used, as well as other approaches to mine complex data from heterogeneous sources.

Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Group/Cohort
Subjects with malodor; individuals with self-reported odor issues suspected to be associated with microbial imbalance on or inside the body and inefficient metabolism as evidenced from other laboratory tests
Healthy control; individuals not complaining of uncontrollable or unpredictable malodor episodes

Outcome Measures

Go to 

Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Differences in metabolite concentrations measured by mass spectrometry, comparing urine samples from individuals with malodor issues, and age-matched healthy controls. [ Time Frame: ten months ]
   The investigators would like to validate if urine metabolomic profiling can be used for identifying key metabolomic signatures associated with malodor

Secondary Outcome Measures :

1. Correlations between urine biomarkers and frequency/severity of malodor symptoms (questionnaires) [ Time Frame: one year ]
   The investigators will comprehensively analyze the ability of metabolite levels to discriminate frequent and severe from non-severe malodor symptoms
