Mortality of workers employed in refractory ceramic fiber manufacturing: An update.

This study evaluates the possible association between refractory ceramic fiber (RCF) exposure and all causes of death. Current and former employees (n = 1,119) hired from 1952 to 1999 at manufacturing facilities in New York (NY) state and Indiana were included. Work histories and quarterly plant-wide sampling from 1987 to 2015 provided cumulative fiber exposure (CFE) estimates.

Atopic dermatitis independently increases sensitization above parental atopy: The MPAACH study.

Early sensitization is ~50% higher in children with atopic dermatitis compared to children from a high-risk allergy cohort with comparable rates of parental atopy. AD may increase sensitization risk over heredity alone.

genetic variation increases asthma risk in children with secondhand smoke exposure.

Objective: We previously reported that children exposed to secondhand smoke (SHS) that carried variants in the NAT1 gene had over two-fold higher hair cotinine levels. Our objective was to determine if NAT1 polymorphisms confer increased risk for developing asthma in children exposed to SHS.

Methods: White participants in the Cincinnati Childhood Allergy and Air Pollution Study ( = 359) were genotyped for 10 variants.

Using high-resolution residential greenspace measures in an urban environment to assess risks of allergy outcomes in children.

Despite reported health benefits of urban greenspace (gs), the epidemiological evidence is less clear for allergic disease. To address a limitation of previous research, we examined the associations of medium- and high-resolution residential gs measures and tree and/or grass canopies with allergic outcomes for children enrolled in the longitudinal cincinnati childhood allergy and air pollution study (ccaaps). We estimated residential gs based on 400 m radial buffers around participant addresses (n = 478) using the normalized differential vegetation index (ndvi) and land cover-derived urban greenspace (ugs) (tree and grass coverage, combined and separate) at 30 m and 1.
