Air Pollution And Preterm Births In Atlanta, Georgia, Corey Masuca

Exposure to ambient outdoor air pollution exposure is one of the many extraneous factors associated with preterm births. Many epidemiological studies involving preterm births and ambient air pollution have repeatedly indicated positive associations. However, for many such studies, results may be statistically significant but weakly associated or inconclusive. Such results may be primarily attributable to the fact that most studies include only single or multiple criteria air pollutants but not the total air pollution mixture of criteria air pollutants and air toxic pollutants (e.g., PAHs) to which people are actually exposed. This study assessed associations between pollutant classes, including criteria …
Gender Difference In Traumatic Brain Injury Outcomes: Survival, Functional Independence, And Employment Status, Andrea T. Underhill
Gender Difference In Traumatic Brain Injury Outcomes: Survival, Functional Independence, And Employment Status, Andrea T. Underhill

Medical and rehabilitative care of women living with traumatic brain injury (TBI) is based on information drawn from research conducted primarily on men. Care for men may be adequate for women, but all of the body’s organs have the capability to respond differently based on gender, and research should examine the genders separately. This dissertation examines the survival to 24 months post-TBI and the functional independence and employment status at 12 and 24 months post-TBI of men and women. Participants were drawn from a longitudinal study of injured persons and include those diagnosed only with a TBI. Variables used in …

Diffusion tensor imaging (DTI) is a magnetic resonance imaging (MRI) technique capable of in vivo characterization of the spatial and angular dependence of free water diffusion in tissue. By studying intra- and extra-cellular water mobility, inference can be made about the surrounding medium. The non-uniform angular dependence of diffusion, known as anisotropy, is evident in fibrous tissues, which exhibit greater diffusion parallel versus perpendicular to the fiber orientation. DTI’s sensitivity to anisotropy makes it an effective tool for measuring the integrity of fibrous myelinated white matter tracts in the brain. For demyelinating diseases such as multiple sclerosis (MS), DTI has …
