Journal ArticleDOI
Preliminary analysis of in utero low-level arsenic exposure and fetal growth using biometric measurements extracted from fetal ultrasound reports.
Matthew A. Davis,John H. Higgins,Zhigang Li,Diane Gilbert-Diamond,Emily R Baker,Emily R Baker,Amar K. Das,Margaret R. Karagas +7 more
TL;DR: It is found that useful data can be extracted directly from electronic medical records for epidemiologic research and exposure to low-level arsenic may be associated with reduced head circumference in a sex dependent manner that warrants further investigation.
Journal ArticleDOI
Intrauterine multi-metal exposure is associated with reduced fetal growth through modulation of the placental gene network
Maya A. Deyssenroth,Chris Gennings,Shelley H. Liu,Shouneng Peng,Ke Hao,Luca Lambertini,Brian P. Jackson,Margaret R. Karagas,Carmen J. Marsit,Jia Chen +9 more
TL;DR: A novel approach that integrates the application of advanced bioinformatics and biostatistics methods to delineate potential placental pathways through which trace metal exposures impact fetal growth is presented.
Journal ArticleDOI
Association of secondhand smoke exposures with DNA methylation in bladder carcinomas
Charlotte Wilhelm-Benartzi,Brock C. Christensen,Devin C. Koestler,E. Andres Houseman,Alan R. Schned,Margaret R. Karagas,Karl T. Kelsey,Carmen J. Marsit +7 more
TL;DR: Exposures to secondhand smoke in adulthood, childhood, occupationally, and in total are each significantly associated with changes in DNA methylation of several CpG loci in bladder tumors, adding biological plausibility to SHS as a risk factor for bladder cancer.
Journal ArticleDOI
Placental metal concentrations in relation to placental growth, efficiency and birth weight
Tracy Punshon,Zhigang Li,Brian P. Jackson,W. Tony Parks,Megan E. Romano,David C Conway,Emily R. Baker,Margaret R. Karagas +7 more
TL;DR: A role of interacting essential and contaminant elements on birth weight that may be mediated by changes in the growth and function of the placenta is suggested.
Journal ArticleDOI
