Preterm Birth And Air Pollution: Critical Windows Of Exposure For Women With Asthma, Pauline Mendola, Maeve Wallace, Beom Seuk Hwang, Danping Liu, Candace Robledo, Tuija Männistö

School of Medicine Publications and Presentations

Background: Ambient air pollutants may increase preterm birth (PTB) risk, but critical exposure windows are uncertain. The interaction of asthma and pollutant exposure is rarely studied.

Objective: We sought to assess the interaction of maternal asthma and air pollutant exposures in relation to PTB risk.

Methods: Electronic medical records for 223,502 US deliveries were linked with modified Community Multiscale Air Quality model outputs. Logistic regression with generalized estimating equations estimated the odds ratio and 95% CIs for PTB on the basis of the interaction of maternal asthma and particulate matter with aerodynamic diameter of less than 2.5 microns and particulate …

A Link Between Paediatric Asthma And Obesity: Are They Caused By The Same Environmental Conditions?, Phylicia Gonsalves

Electronic Thesis and Dissertation Repository

The highly associated paediatric conditions of asthma and overweight have seen dramatic increases over the past few decades. This thesis explored air pollution exposure as a potential underlying mechanism of co-morbid asthma and overweight among adolescents aged 12 to 18 years. Data from the Canadian Community Health Survey were merged with a database containing estimates of air pollution as assessed by particulate matter ≤ 2.5 microns (PM_2.5) concentrations at the postal code centroid in southwestern Ontario. Logistic regression was used to conduct the analysis. Adolescents were more likely to be overweight as PM_2.5 concentrations increased. There was …

Modeling The Spatiotemporal Dynamics Of Cells In The Lung, Joshua Jeremy Pothen

Graduate College Dissertations and Theses

Multiple research problems related to the lung involve a need to take into account the spatiotemporal dynamics of the underlying component cells. Two such problems involve better understanding the nature of the allergic inflammatory response to explore what might cause chronic inflammatory diseases such as asthma, and determining the rules underlying stem cells used to engraft decellularized lung scaffolds in the hopes of growing new lungs for transplantation. For both problems, we model the systems computationally using agent-based modeling, a tool that enables us to capture these spatiotemporal dynamics by modeling any biological system as a collection of agents (cells) …

Patterns Of Asthma Exacerbation Related To Climate And Weather In The Northeast Kingdom Of Vermont, Quincy Mckenzie Campbell

Graduate College Dissertations and Theses

Asthma is a chronic respiratory disease characterized by long- and short-term inflammation and bronchospasm susceptible to multiple triggers that affects patients across the lifespan. Asthma management is a primary care priority in Vermont, where there continues to be an above-average prevalence of asthma among both children and adults as compared to other states. However, many of Vermont's children and especially adults with asthma are not participating in regular check-ups for asthma management that would best prevent exacerbation of asthma symptoms. Several climate and weather elements including, but not limited to, extreme temperatures and particulate matter are known asthma triggers. Vermont's …
