Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

An Emerging Approach To Ibd Treatment: Personalized Nutrition Through Gut Microbiome Optimization., Kafayat Yusuf, Thomas M. Attard, Mazin Al-Kasspooles, Shahid Umar

Manuscripts, Articles, Book Chapters and Other Papers

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract characterized by relapsing and remitting disease activity. Despite decades of research, a definitive cure for IBD remains elusive, as cycles of remission and flare-ups mark the disease course and often relies on long-term pharmacologic and supportive strategies. Increasing evidence indicates that diet and nutrition play an important role in modulating the outcomes of IBD. Although a wide range of dietary interventions has been explored, no universally effective approach has been established. Investigations have also proven that different dietary interventions can significantly affect clinical outcomes by altering gut …

Enhancing The Well-Being Of Refugees With Disabilities Through Equitable Access To Essential Services: A Participatory Qualitative Study In The United States, Mustafa Rfat

Brown School Graduate Student Theses and Dissertations

Access to services for refugees with disabilities (RwDs) is critically important for improving their well-being and enhancing their integration. This population often faces prolonged exclusion that begins in their country of origin and often continues to worsen during displacement, leading to accumulated disparities. Because the United States (U.S.) refugee program is structured around rapid employment, refugees who do not fit the fast-track employment criteria are often left behind. RwDs are often considered unemployable, which automatically shifts resources and services away from them. Abandoning RwDs during the critical period of resettlement puts them at heightened risk of increased and long-term exclusion. …

The Fungus Among Us: Latency, Reactivation, And The Expanding Clinical Spectrum Of Coccidioidomycosis, Sumeet Bhardwaj, Arushi Tewari, Rishima Tewari, Simona Kogan

Student Publications

Coccidioidomycosis is a serious fungal infection that can produce a wide range of clinical manifestations, from mild, self-limiting pulmonary disease to severe, disseminated infection that can involve nearly any organ system, including the skin. Coccidioidomycosis may also affect patients at the psychiatric level. Its clinical relevance has increased markedly in recent years, as incidence continues to climb, geographic distribution widens, and emerging presentations challenge traditional assumptions regarding fungal latency and host immunity. A notably important and developing area of study is the concept of late reactivation. A narrative review of the literature was conducted using PubMed, MEDLINE, and Google Scholar. …

The Social Determinants Of Health And Cancer, Joshua Williams

Ex Sapientia Loqui

The social determinants of health, as defined by the World Health Organization (WHO), are “the conditions in which people are born, grow, live, work and age, and people’s access to power, money and resources.” Epidemiologists have long studied the nexus between social forces and disease and have widely agreed that such forces are directly causal of pathologies. This paper is an analytic review of the existing literature on several social determinants— namely socioeconomic status (SES), race and ethnicity, age, working and living conditions, and social integration— and how they pertain to the causation, progression, and treatment of cancer.
