Individuals exposed to inhaled endotoxin (lipopolysaccharide [LPS]) can develop airway symptomatology and exacerbations of asthma. Moreover, among those occupationally exposed to organic dusts, the progression of airflow obstruction is related to the endotoxin concentration in the bioaerosol. Not everyone exposed to high concentrations of LPS develops these(More)
Given the minimal developmental neurotoxicity data available for the large number of new and existing chemicals, there is a critical need for alternative methods to identify and prioritize chemicals for further testing. We outline a developmental neurotoxicity screening approach using zebrafish embryos. Embryos were exposed to nominal concentrations of(More)
OBJECTIVE Socioeconomic status (SES) is inversely related to pediatric mortality in the community. However, it is unknown if this association exists for in-hospital pediatric mortality. Our objective was to determine the association of SES with in-hospital pediatric mortality among children's hospitals and to compare observed mortality with expected(More)
BACKGROUND Oral exposure to inorganic arsenic (iAs) is associated with adverse health effects. Epidemiological studies suggest differences in susceptibility to these health effects, possibly due to genotypic variation. Genetic polymorphisms in iAs metabolism could lead to increased susceptibility by altering urinary iAs metabolite concentrations. (More)
Increasing use of engineered nanomaterials (ENM) in consumer products and commercial applications has helped drive a rise in research related to the environmental health and safety (EHS) of these materials. Within the cacophony of information on ENM EHS to date are data indicating that these materials may be neurotoxic in adult animals. Evidence of elevated(More)
Childhood obesity is a major public health problem in the United States and is associated with numerous comorbidities. The relationship of obesity to risk of traumatic injury and recovery has been described, although not in depth. In adults with burns, obesity has been linked to negative impact on functional outcomes as well as increased mortality. Less is(More)
Small aquarium fishes are increasingly used as animal models, and one of these, the Japanese Medaka (Oryzias latipes), is frequently utilized for toxicity testing. While these vertebrates have many similarities with their terrestrial counterparts, there are differences that must be considered if these organisms are to be used to their highest potential.(More)
Hazard information essential to guide developmental neurotoxicity risk assessments is limited for many chemicals. As developmental neurotoxicity testing using rodents is laborious and expensive, alternative species such as zebrafish are being adapted for rapid toxicity screening. Assessing the developmental neurotoxicity potential of chemicals in a rapid(More)
BACKGROUND Asthma care plans typically include complicated written instructions. Customized, audio-recorded instructions may bridge health literacy gaps and improve treatment plan understanding. OBJECTIVE To measure the effects of a recordable greeting card-style tool (Talking Card) on asthma control and parental care of children with asthma. METHODS(More)
