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. There are significant gaps in our understanding of critical host-parasite factors that mediate hookworm infection, reinfection, and response to deworming treatment in endemic communities. A five-year prospective study was undertaken to better understand drivers of hookworm infection in rural Ghana and thus …

Institutionalized Stigmas: Hiv Stigma, Racism And Heterosexism Among Medical Students In The Southern United States, Krishen D. Samuel

Graduate Theses and Dissertations

Background: Intersecting and related forms of stigma, including HIV-related stigma, racism, and heterosexism, disproportionately impact both communities vulnerable to acquiring HIV and people living with HIV (PLHIV), ultimately impacting more distal outcomes related to HIV prevention, treatment, and epidemiological patterns in the United States (US). The Southern US is the region most impacted by new HIV diagnoses, mainly among Black men who have sex with men (MSM). However, there is a paucity of research on medical students, specifically those in the Southern US, regarding stigmatizing attitudes they may hold towards PLHIV, and how these associate with racism and heterosexism. This …

The Role Of Cosmopolitan Orientation In Covid-19-Related Attitudes: Perceived Threats And Opportunities, Vaccination Willingness, And Support For Collective Containment Efforts, Angela K. Y. Leung, Brandon Koh, Verity Yu Qing Lua, James H. Liu, Sarah Y. Choi, I-Ching Lee, Michelle Lee, Mei-Hua Lin, Darrin Hodgetts, Sylvia X. Chen

Research Collection School of Social Sciences

Cosmopolitan individuals identify themselves as "citizens of the world." In the present research, we tested the idea that endorsing a cosmopolitan orientation (CO) is adaptive in the COVID-19 crisis. Cosmopolitan individuals more readily transcend national parochialism, show greater concern for all humanity, and prioritize collective interests. In a two-wave multi-region investigation with six samples from China, Hong Kong, Taiwan, Malaysia, Singapore, and the U.S., we first established longitudinal and cross-cultural measurement invariance of the CO scale. Next, we found that people with a higher CO tended to perceive over time a greater threat posed by COVID-19, take more safety measures, …

Internalization from the cell membrane and endosomal trafficking of receptor tyrosine kinases (RTKs) are important regulators of signaling in normal cells that can frequently be disrupted in cancer. The adrenal tumor pheochromocytoma (PCC) can be caused by activating mutations of the rearranged during transfection (RET) receptor tyrosine kinase, or inactivation of TMEM127, a transmembrane tumor suppressor implicated in trafficking of endosomal cargos. However, the role of aberrant receptor trafficking in PCC is not well understood. Here, we show that loss of TMEM127 causes wildtype RET protein accumulation on the cell surface, where increased receptor density facilitates constitutive ligand-independent activity and …

Modeling The Transmission Dynamics Of Tuberculosis In Humans, Farida Kisinda, Joshua A. Mwasunda, Mbwiga S. Aloni

Tanzania Journal of Science

Tuberculosis (TB) is a major threat to human health particularly in most of developing countries. In this article, we formulate and analyze a deterministic model for the transmission dynamics of pulmonary and extra-pulmonary tuberculosis. The next generation method is employed to find the basic reproduction number which helps to determine whether TB clears or persists in the human population. Global stability of model equilibria is done through Lyapunov functions whereas the normalized forward sensitivity index method is adopted to determine parameters that drive tuberculosis. Analysis shows that both TB free and endemic equilibria exist. The TB free equilibrium is globally …

Modelling The Combined Use Of Long-Lasting Insecticidal Nets And Insecticides Zooprophylaxis Against The Resilience Of Anopheles Arabiensis For Effective Malaria Control, Watson Levens

Tanzania Journal of Science

Malaria is a significant public health concern, especially in tropical regions. It remains endemic in many areas where malaria mosquitoes are prevalent. This study investigates the viability of insecticide zooprophylaxis (IZ) in conjunction with Long Lasting Insecticidal Nets (LLINs) as a strategic approach to combat malaria transmission, particularly in regions dominated by zoophagic vectors. Through the presentation and analysis of a mathematical model that integrates IZ and LLINs for the control of Anopheles arabiensis (An. arabiensis), the research underscores IZ's role in reducing zoophagic vector populations and enhancing malaria control efforts.

Dispelling The Malaria-Typhoid Co-Infection Myth In Nigeria. A Literature Review, Olawale Akinola

Dartmouth Library Staff Publications

Malaria and typhoid fever are public health concerns in Nigeria, with high prevalence rates. The perception of a widespread co-infection between these diseases may be misleading, due to limitations in diagnostic methods, particularly the Widal test for typhoid fever. This literature review examines the prevalence of malaria-typhoid co-infection in Nigeria and identifies factors contributing to misdiagnosis, including non-specific symptoms, limited diagnostic resources, and the diagnostic accuracy of tests employed. Additionally, the review discusses the implications of misdiagnosis, such as the overuse of broad-spectrum antibiotics leading to a rising incidence of antimicrobial resistance. Strategies to address this issue are explored, emphasizing …

Modeling An Infection Outbreak With Quarantine: The Sibkr Model, Mikenna Dew, Amanda Langosch, Theadora Baker-Wallerstein

Rose-Hulman Undergraduate Mathematics Journal

Influenza is a respiratory infection that places a substantial burden in the world population each year. In this project, we study and interpret a data set from a flu outbreak in a British boarding school in 1978 with mathematical modeling. First, we propose a generalization of the SIR model based on the quarantine measure in place and establish the long-time behavior of the model. By analyzing the model mathematically, we determine the analytic formulas of the basic reproduction number, the long-time limit of solutions, and the maximum number of infection population. Moreover, we estimate the parameters of the model based …
