Journal ArticleDOI
Risk of keratinocyte carcinomas with vitamin D and calcium supplementation: a secondary analysis of a randomized clinical trial.
Michael N. Passarelli,Margaret R. Karagas,Leila A. Mott,Judy R. Rees,Elizabeth L. Barry,John A. Baron,John A. Baron +6 more
TL;DR: Calcium alone or in combination with vitamin D may reduce the risk of SCC, but not BCC, and there was suggestive evidence of beneficial treatment effects for calcium compared with no calcium.
Journal ArticleDOI
Copper associates with differential methylation in placentae from two US birth cohorts
Elizabeth M. Kennedy,Todd M. Everson,Tracy Punshon,Brian P. Jackson,Ke Hao,Luca Lambertini,Jia Chen,Margaret R. Karagas,Carmen J. Marsit,Carmen J. Marsit +9 more
TL;DR: It is suggested that copper metabolism is tied to DNAm in the placenta and that copper-associated patterns in DNAm may mediate normal placentation and foetal development.
Journal ArticleDOI
Residential wood stove use and indoor exposure to PM2.5 and its components in Northern New England.
Abby F. Fleisch,Lisa B. Rokoff,Eric Garshick,Stephanie T. Grady,Jonathan W. Chipman,Emily R Baker,Petros Koutrakis,Margaret R. Karagas +7 more
TL;DR: Homes with wood stoves, particularly those that were older and non-EPA-certified or burning wet wood had higher concentrations of indoor air combustion-related pollutants and black carbon was associated with higher pollutant concentrations.
Journal ArticleDOI
Sampling private wells at past homes to estimate arsenic exposure: a methodologic study in New England.
Joanne S. Colt,Dalsu Baris,Stewart F Clark,Joseph D. Ayotte,Mary H. Ward,John R. Nuckols,Kenneth P. Cantor,Debra T. Silverman,Margaret R. Karagas +8 more
TL;DR: Various approaches for improving the success rates for sampling water from private wells are discussed, as is the use of predictive modeling to impute exposures when sampling is not feasible.
Journal ArticleDOI
Functional dyadicity and heterophilicity of gene-gene interactions in statistical epistasis networks
TL;DR: The informatics framework suggests a new methodology for embedding functional analysis in network modeling of statistical epistasis in genetic association studies by identifying several GO categories that have significant dyadicity or heterophilicity associated with bladder cancer susceptibility.
