Air Pollution and ST-Segment Depression in Elderly Subjects
(National Institue of Environmental Health Sciences, 2005)
Increased levels of daily ambient particle pollution have been associated with increased risk of cardiovascular morbidity. Black carbon (BC) is a measure of the traffic-related component of particles. We investigated ...
Annual Ambient Black Carbon Associated with Shorter Telomeres in Elderly Men: Veterans Affairs Normative Aging Study
(National Institute of Environmental Health Sciences, 2010)
Background: Telomere length reflects biological age and is inversely associated with risk of cardiovascular disease (CVD). Ambient air pollution is associated with CVD, but its effect on telomere length is unknown. Objective: ...
Diabetes, Obesity, and Hypertension May Enhance Associations between Air Pollution and Markers of Systemic Inflammation
(National Institute of Environmental Health Sciences, 2006)
Airborne particulate matter (PM) may lead to increased cardiac risk through
an inflammatory pathway. Therefore, we investigated associations
between ambient PM and markers of systemic inflammation among repeated
measures ...
Increased Risk of Paroxysmal Atrial Fibrillation Episodes Associated with Acute Increases in Ambient Air Pollution
(National Institute of Environmental Health Sciences, 2006)
Objectives: We reported previously that 24-hr moving average ambient air pollution concentrations were positively associated with ventricular arrhythmias detected by implantable cardioverter defibrillators (ICDs). ICDs ...
Estimating the Independent Effects of Multiple Pollutants in the Presence of Measurement Error: An Application of a Measurement-Error–Resistant Technique
(2004)
Misclassification of exposure usually leads to biased estimates of exposure–response associations. This is particularly an issue in cases with multiple correlated exposures, where the direction of bias is uncertain. It is ...
Is the Association of Airborne Particles with Daily Deaths Confounded by Gaseous Air Pollutants? An Approach to Control by Matching
(National Institute of Environmental Health Sciences, 2004)
Although particulate air pollution has been associated with increased numbers of daily deaths in dozens of cities around the world, issues still remain about the association. Some have questioned the complex modeling used ...
Factors Affecting the Association between Ambient Concentrations and Personal Exposures to Particles and Gases
(National Institute of Environmental Health Sciences, 2005)
Results from air pollution exposure assessment studies suggest that ambient fine particles [particulate matter with aerodynamic diameter ≤ 2.5 μg (PM2.5)], but not ambient gases, are strong proxies of corresponding personal ...
Particulate air pollution, oxidative stress genes, and heart rate variability in an elderly cohort
(National Institute of Environmental Health Sciences, 2007)
Background and Objectives: We have previously shown that reduced defenses against oxidative stress due to glutathione S-transferase M1 (GSTM1) deletion modify the effects of PM[2.5] (fine-particulate air pollution of < 2.5 ...
Air conditioning and source-specific particles as modifiers of the effect of PM(10) on hospital admissions for heart and lung disease.
(National Institute of Environmental Health Sciences, 2002)
Studies on acute effects of particulate matter (PM) air pollution show significant variability in exposure-effect relations among cities. Recent studies have shown an influence of ventilation on personal/indoor-outdoor ...
Metabolic syndrome and inflammatory responses to long-term particulate air pollutants
(National Institute of Environmental Health Sciences, 2008)
Background: Human data linking inflammation with long-term particulate matter (PM) exposure are still lacking. Emerging evidence suggests that people with metabolic syndrome (MS) may be a more susceptible population. ...
