Journal ArticleDOI

Eric Lavigne,Jessy Donelle,Marianne Hatzopoulou,Keith Van Ryswyk,Aaron van Donkelaar,Randall V. Martin,Randall V. Martin,Hong Chen,David M. Stieb,Antonio Gasparrini,Eric J. Crighton,Abdool S. Yasseen,Richard T. Burnett,Mark Walker,Mark Walker,Scott Weichenthal +15 more
TL;DR: Exposure to UFPs during a critical period of lung development was linked to the onset of asthma in children, independent of PM2.5 and NO2.2, and exposure during the second trimester of pregnancy remained positively associated with asthma incidence.
Journal ArticleDOI
Occurrence and predictors of cesarean delivery for the second twin after vaginal delivery of the first twin.
TL;DR: Prediction of emergent cesarean for the second twin by clinical factors was stronger in term births than preterm births and in infants born to mothers with medical or labor and delivery complications.
Journal ArticleDOI
Temporal variability and sources of triclosan exposure in pregnancy.
Lorelle Weiss,Tye E. Arbuckle,Mandy Fisher,Tim Ramsay,Ranjeeta Mallick,Russ Hauser,Alain LeBlanc,Mark Walker,Pierre Dumas,Carly Lang +9 more
TL;DR: The first data on temporal variability of urinary TCS concentrations and predictors of exposure in Canadian pregnant women is provided and can inform exposure assessments in pregnant women and justify collection of single spot urine samples in epidemiologic studies, especially for women with higher exposures.
Journal ArticleDOI

TL;DR: KF6 regulation of GCK contributes to the development of hepatic insulin resistance, and the KLF6‐IVS1‐27A polymorphism, which generates more KLF 6‐SV1, combats this, lowering hepatic diabetes resistance and blood glucose.
Journal ArticleDOI
Effect modification of perinatal exposure to air pollution and childhood asthma incidence

TL;DR: Enhanced impacts were found among children born to mothers with asthma, who smoked during pregnancy or lived in urban areas during pregnancy, males and children born preterm or of low birthweight.
