Background: Coronary artery calcium (CAC) is heterogeneous in older age and is incompletely explained by traditional atherosclerotic cardiovascular disease risk factors. The extremes of subclinical atherosclerosis burden are strongly associated with either a low or high 10-year risk of incident atherosclerotic cardiovascular disease, respectively. However, the genetic underpinnings of differences in arterial aging remain unclear. We sought to determine the independent association of 2 polygenic scores for coronary heart disease (CHD) with CAC in adults ≥75 years of age.

Methods: There were 1865 ARIC (Atherosclerosis Risk in Communities) participants who underwent genetic testing at visit 1 (1987-1989) and CAC scans …

The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux Jul 2024

The Role Of Sexual Network Core Groups In Disease Epidemics, Jason Janeaux

LSU Doctoral Dissertations

Sexually transmitted infections (STIs) remain an economic and social burden, non-discriminately affecting sexually active individuals worldwide. The unique transmission of STIs is dependent upon host and pathogen life histories, as well as the underlying network structure of the host population. Within a population there is a group of individuals, the core group, that maintains STI presence and helps sustain ongoing transmission both within the core group and in the surrounding population. While the presence of these core groups is well documented, the criteria for inclusion into a sexual core group is not. In this dissertation, I explore common factors that …

One Year Follow Up Of A Cross-Sectional Study Of Hookworm Infection And Response To Deworming In Beposo, Ghana, Taylor Clarkson May 2024

One Year Follow Up Of A Cross-Sectional Study Of Hookworm Infection And Response To Deworming In Beposo, Ghana, Taylor Clarkson

Capstone Experience: Master of Public Health

Hookworms are soil-transmitted helminths that infect over 500 million people worldwide, primarily those in low-income countries. Infection with hookworm can cause anemia, malnutrition, and stunted physical and cognitive development. Deworming campaigns have attempted to combat hookworm infections in endemic areas for decades. However, there is growing variability in the effectiveness of deworming drugs, and post-treatment reinfections are abundant.
