The effect of weather on respiratory and cardiovascular deaths in 12 U.S. cities.
(National Institute of Environmental Health Sciences, 2002)
We carried out time-series analyses in 12 U.S. cities to estimate both the acute effects and the lagged influence of weather on respiratory and cardiovascular disease (CVD) deaths. We fit generalized additive Poisson ...
PM\(_{2.5}\) metal exposures and nocturnal heart rate variability: a panel study of boilermaker construction workers
(BioMed Central, 2008)
Background: To better understand the mechanism(s) of particulate matter (PM) associated cardiovascular effects, research priorities include identifying the responsible PM characteristics. Evidence suggests that metals play ...
Baseline Repeated Measures from Controlled Human Exposure Studies: Associations between Ambient Air Pollution Exposure and the Systemic Inflammatory Biomarkers IL-6 and Fibrinogen
(National Institute of Environmental Health Sciences, 2009)
Introduction: Systemic inflammation may be one of the mechanisms mediating the association between ambient air pollution and cardiovascular morbidity and mortality. Interleukin-6 (IL-6) and fibrinogen are biomarkers of ...
The Effect of Particulate Air Pollution on Emergency Admissions for Myocardial Infarction: A Multicity Case-Crossover Analysis
(National Institute of Environmental Health Sciences, 2005)
Recently, attention has focused on whether particulate air pollution is a specific trigger of myocardial infarction (MI). The results of several studies of single locations assessing the effects of ambient particular matter ...
Differences in Heart Rate Variability Associated with Long-Term Exposure to NO2
(National Institute of Environmental Health Sciences, 2008)
Background: Heart rate variability (HRV), a measure of cardiac autonomic tone, has been associated with cardiovascular morbidity and mortality. Short-term studies have shown that subjects exposed to higher traffic-associated ...
Associations between outdoor temperature and markers of inflammation: a cohort study
(BioMed Central, 2010)
Background: Associations between ambient temperature and cardiovascular mortality are well established. This study investigated whether inflammation could be part of the mechanism leading to temperature-related cardiovascular ...
Reduction in Heart Rate Variability with Traffic and Air Pollution in Patients with Coronary Artery Disease
(National Institute of Environmental Health Sciences, 2009)
Introduction: Ambient particulate pollution and traffic have been linked to myocardial infarction and cardiac death risk. Possible mechanisms include autonomic cardiac dysfunction. Methods: In a repeated-measures study of ...
A delta-aminolevulinic acid dehydratase (ALAD) polymorphism may modify the relationship of low-level lead exposure to uricemia and renal function: the normative aging study.
(2003)
In this study we investigated whether a known delta-aminolevulinic acid dehydratase (ALAD) exon 4 polymorphism has a modifying effect on the association of blood or bone lead level with uricemia and indices of renal function ...
Association between leukocyte telomere shortening and exposure to traffic pollution: a cross-sectional study on traffic officers and indoor office workers
(BioMed Central, 2009)
Background: Telomere shortening in blood leukocytes has been associated with increased morbidity and death from cardiovascular disease and cancer, but determinants of shortened telomeres, a molecular feature of biological ...
Effects of air pollution on heart rate variability: the VA Normative Aging Study
(National Institue of Environmental Health Sciences, 2004)
Reduced heart rate variability (HRV), a marker of poor cardiac autonomic function, has been associated with air pollution, especially fine particulate matter [< 2.5 μm in aerodynamic diameter (PM\(_{2.5}\))]. We examined ...
