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 ...
Acute and Chronic Effects of Particles on Hospital Admissions in New England
(Public Library of Science, 2012)
Background: Many studies have reported significant associations between exposure to \(PM_{2.5}\) and hospital admissions, but all have focused on the effects of short-term exposure. In addition all these studies have relied ...
Alu and LINE-1 methylation and lung function in the normative ageing study
(BMJ Publishing Group, 2012)
Objectives: To investigate the association between methylation of transposable elements Alu and long-interspersed nuclear elements (LINE-1) and lung function. Design: Cohort study. Setting: Outpatient Veterans Administration ...
Influenza epidemics, seasonality, and the effects of cold weather on cardiac mortality
(BioMed Central, 2012)
Background: More people die in the winter from cardiac disease, and there are competing hypotheses to explain this. The authors conducted a study in 48 US cities to determine how much of the seasonal pattern in cardiac ...
Opposing Effects of Particle Pollution, Ozone, and Ambient Temperature on Arterial Blood Pressure
(National Institute of Environmental Health Sciences, 2012)
Background: Diabetes increases the risk of hypertension and orthostatic hypotension and raises the risk of cardiovascular death during heat waves and high pollution episodes. Objective: We examined whether short-term ...
Air Pollution, Smoking, and Plasma Homocysteine
(National Institute of Environmental Health Sciences, 2006)
Background: Mild hyperhomocysteinemia is independently associated with an increased risk of cardiovascular disease. Air pollution exposure induces short-term inflammatory changes that may determine hyperhomocysteinemia, ...
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 ...
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 ...
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 ...
