Study TitleBiological Responses to Tobacco Smoke Exposure in III Children: Inflammatory Processes and the Oral Microbiome
Study SummaryThis project evaluates the biological response to overall tobacco smoke (OTS) exposure among pediatric emergency patients enrolled in a randomized-controlled intervention trial aimed at reducing secondhand smoke exposure. The effects of OTS as measured by salivary continine on salivary metabolic profiles are measured by untargeted high resolution metabolomics, comparing higher and lower levels of OTS.
