• 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 ...
• The Effect of Dose and Timing of Dose on the Association between Airborne Particles and Survival ﻿

(2008)
BACKGROUND: Understanding the shape of the concentration–response curve for particles is important for public health, and lack of such understanding was recently cited by U.S. Environmental Protection Agency (EPA) as a ...
• The effect of primary organic particles on emergency hospital admissions among the elderly in 3 US cities ﻿

(BioMed Central, 2013)
Background: Fine particle (PM2.5) pollution related to combustion sources has been linked to a variety of adverse health outcomes. Although poorly understood, it is possible that organic carbon (OC) species, particularly ...
• Effects of Ambient Air Pollution on Functional Status in Patients with Chronic Congestive Heart Failure: a Repeated-Measures Study ﻿

(BioMed Central, 2007)
Background: Studies using administrative data report a positive association between ambient air pollution and the risk of hospitalization for congestive heart failure (HF). Circulating levels of B-type natriuretic peptide ...
• Effects of Prenatal Social Stress and Maternal Dietary Fatty Acid Ratio on Infant Temperament: Does Race Matter? ﻿

(2014)
Background: Infant temperament predicts a range of developmental and behavioral outcomes throughout childhood. Both maternal fatty acid intake and psychosocial stress exposures during pregnancy may influence infant ...
• Estimating Causal Effects of Long-Term PM2.5 Exposure on Mortality in New Jersey ﻿

(National Institute of Environmental Health Sciences, 2016)
Background: Many studies have reported the associations between long-term exposure to PM2.5 and increased risk of death. However, to our knowledge, none has used a causal modeling approach or controlled for long-term ...
• Exposure to sub-chronic and long-term particulate air pollution and heart rate variability in an elderly cohort: the Normative Aging Study ﻿

(BioMed Central, 2015)
Background: Short-term particulate air pollution exposure is associated with reduced heart rate variability (HRV), a risk factor for cardiovascular morbidity and mortality, in many studies. Associations with sub-chronic ...
• 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 ...
• Function-on-Function Regression with Public Health Applications ﻿

(2014-06-06)
Medical research currently involves the collection of large and complex data. One such type of data is functional data where the unit of measurement is a curve measured over a grid. Functional data comes in a variety of ...
• Impact of biomass fuels on pregnancy outcomes in central East India ﻿

(BioMed Central, 2014)
Background: Smoke from biomass burning has been linked to reduced birth weight; association with other birth outcomes is poorly understood. Our objective was to evaluate effects of exposure to biomass smoke on birth weight, ...
• The Impact of Nitrogen Oxides Concentration Decreases on Ozone Trends in the USA ﻿

(Springer Nature, 2014-07-25)
Ozone (O-3) has harmful effects on human health and ecosystems. In the USA, significant reductions of O-3 precursors-nitrogen oxides (NOx) and volatile organic compounds (VOCs)-have not yielded proportionate decreases in ...
• The impact of source contribution uncertainty on the effects of source-specific PM2.5 on hospital admissions: A case study in Boston, MA ﻿

(Nature Publishing Group, 2014)
Epidemiologic studies of particulate sources and adverse health do not account for the uncertainty in the source contribution estimates. Our goal was to assess the impact of uncertainty on the effect estimates of particulate ...
• The impact of weather changes on air quality and health in the United States in 1994–2012 ﻿

(2016)
Air quality is heavily influenced by weather conditions. In this study, we assessed the impact of long-term weather changes on air quality and health in the US during 1994–2012. We quantified past weather-related increases, ...
• Lifetime Socioeconomic Position and Twins' Health: An Analysis of 308 Pairs of United States Women Twins ﻿

(Public Library of Science, 2005)
Background: Important controversies exist about the extent to which people's health status as adults is shaped by their living conditions in early life compared to adulthood. These debates have important policy implications, ...
• Long-term Exposure to $PM_{2.5}$ and Incidence of Acute Myocardial Infarction ﻿

(National Institute of Environmental Health Sciences, 2013)
Background: A number of studies have shown associations between chronic exposure to particulate air pollution and increased mortality, particularly from cardiovascular disease, but fewer studies have examined the association ...
• Long-term Exposure to Black Carbon and Carotid Intima-Media Thickness: The Normative Aging Study ﻿

(National Institute of Environmental Health Sciences, 2013)
Background: Evidence suggests that air pollution is associated with atherosclerosis and that traffic-related particles are a particularly important contributor to the association. Objectives: We investigated the association ...
• Longitudinal associations of age and prenatal lead exposure on cortisol secretion of 12–24 month-old infants from Mexico City ﻿

(BioMed Central, 2016)
Background: Cortisol has functions on homeostasis, growth, neurodevelopment, immune function and the stress response. Secretion follows a diurnal rhythm that mediates these processes. Our objective was to examine the ...
• Low-Concentration PM2.5 and Mortality: Estimating Acute and Chronic Effects in a Population-Based Study ﻿

(National Institute of Environmental Health Sciences, 2015)
Background: Both short- and long-term exposures to fine particulate matter (≤ 2.5 μm; PM2.5) are associated with mortality. However, whether the associations exist at levels below the new U.S. Environmental Protection ...
• Low-Level Lead Exposure, Metabolic Syndrome, and Heart Rate Variability: The VA Normative Aging Study ﻿

(National Institute of Environmental Health Sciences, 2006)
Background: Altered heart rate variability (HRV), a marker of poor cardiac autonomic function, has been associated with sudden cardiac death and heart failure. Objective: We examined the association of low-level lead ...
