United States Population Future Estimates And Long-Term Distribution, Sean P. Brogan May 2018

United States Population Future Estimates And Long-Term Distribution, Sean P. Brogan

DePaul Discoveries

The population of the United States has always increased year over year. Even now with decreasing birth rates, the overall population continues to grow when looking at conventional models. The present study specifically examines what would happen to the U.S. population if we were to maintain the current birth and survival rates into the future. By 2050, our research shows that the U.S. population will become much older and cease to grow at all.

The urban ecosystems we inhabit provide essential ecosystem services to humans, such as air pollution removal, as well as effective means to avoid costs related to urban development, such as stormwater treatment. A better understanding of the value of ecosystem services and their spatial distribution in urban areas is vital to widespread, wholistic understanding of the relationship of environmental, economic, and social conditions. As such, it should be a component of education in grades 6-12, college, and continuing education. i-Tree Landscape is a free, online model developed by the USDA Forest Service in which users can select a geography (i.e. …


Potential Mechanisms For Nns-Induced Metabolic Deviances: Satiety Hormone Secretion And Alterations In The Gut Microbiota, Kyle J. Decker May 2018

Potential Mechanisms For Nns-Induced Metabolic Deviances: Satiety Hormone Secretion And Alterations In The Gut Microbiota, Kyle J. Decker

DePaul Discoveries

Rising rates of obesity and type 2 diabetes have prompted the usage and recommendation of nonnutritive sweeteners (NNS) as harmless sugar substitutes in attempts to decrease caloric intake. Contrary to the common belief that NNS remain physiologically inert post-consumption, evidence highlights their ability to alter metabolic processes via interactions in the gastrointestinal tract. An extensive review was conducted on the potential NNS-induced metabolic deviances by way of two non-mutually exclusive mechanisms. One possible mechanism involves their ability (or inability) to induce the secretion of GLP-1, a hormone produced in the gut that promotes satiety and accelerates glucose-dependent insulin secretion by …


Risk Factors Associated With Missed Medical Appointments Among Hiv-Positive Young Men Who Have Sex With Men, Willie Love, Douglas Bruce May 2018

Risk Factors Associated With Missed Medical Appointments Among Hiv-Positive Young Men Who Have Sex With Men, Willie Love, Douglas Bruce

DePaul Discoveries

Young men who have sex with men (YMSM) are overrepresented in the HIV epidemic in America. Retaining HIV positive YMSM in HIV care is very critical to reduce the overall burden of the HIV epidemic in America. Our study focused on identifying significant risk factors that affects retention in care for YMSM. Missing two or more medical appointments was how we measured retention in care. Using data gathered from ATN 086-106 study. This ATN cross-sectional study provided HIV positive males and females between the ages of 12 and 24 with an extensive questionnaire. The goal of this study was to …


Correlates Of Adherence To Antiretroviral Therapy Among Hiv-Positive Young Men Who Have Sex With Men, Janelle Flores, Douglas Bruce May 2018

Correlates Of Adherence To Antiretroviral Therapy Among Hiv-Positive Young Men Who Have Sex With Men, Janelle Flores, Douglas Bruce

Adherence to antiretroviral therapy (ART) is important in HIV management. The objective of this study was to analyze the risk factors for non-adherence to ART in HIV-positive young men who have sex with men (YMSM). Data pertaining to possible risk factors for non-adherence was collected from ATN086-106, a study protocol within the Adolescent Trials Network of HIV/AIDS Interventions (ATN). Variables that were significantly associated with non-adherence to ART in bivariate analyses were entered into multivariate logistic regression models to identify correlates of non-adherence to ART. The results indicate that YMSM who used marijuana and methamphetamine and missed medical appointments were …
