Since the early 1990s, there has been a dramatic rise in gastrointestinal cancers diagnosed in patients under age 50 for reasons that remain poorly understood. The most significant change has been the increase in incidence rates of early-onset colorectal cancer, especially rates of left-sided colon and rectal cancers. Increases in gastric, pancreatic, and other gastrointestinal cancer diagnoses have further contributed to this trend. We formed a multidisciplinary Think Tank to develop a strategic, coordinated approach to studying early-onset gastrointestinal cancers. This area of research is challenging given multifactorial etiologies. We focused on epidemiology and the environment, the microbiome, and survivorship …

2020-Current year OA Pubs

BACKGROUND: Antiretroviral therapy (ART) is recommended for all individuals with HIV infection, including those with acute HIV-1 infection (AHI). While recommendations are similar to those for chronic infection, efficacy data regarding treatment of acute HIV is limited.

METHODS: This was a single arm, 96-week study of a once-daily integrase inhibitor (INSTI)-based regimen using elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF) in AHI. Primary endpoint was proportion of participants with HIV-1 RNA <200 copies/mL and <50 copies/mL by treatment weeks 24 and 48, respectively. We also examined time to viral suppression and weight gain after treatment initiation. Outcomes and characteristics were compared with a historical AHI cohort using a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen with efavirenz/emtricitabine/tenofovir disoproxil fumarate (EFV/FTC/TDF).

RESULTS: Thirty-three participants with AHI were enrolled with 31 available for analyses. Most were African American (61%) and men who have sex with men (73%). Median age was 26 (IQR 22-42). Demographics …

Mouse models are vital tools for discerning the relative contributions of host and microbial genetics to disease, often requiring the transfer of microbiota between different mouse strains. Transfer methods include antibiotic treatment of recipients and colonization using either co-housing with donors or the transplantation of faecal or caecal donor material. However, the efficiency and dynamics of these methods in reconstituting recipients with donor microbes is not well understood. We thus directly compared co-housing, faecal transplantation, and caecal transplantation methods. Donor mice from Taconic Biosciences, possessing distinct microbial communities, served as the microbial source for recipient mice from Jackson Laboratories, which …

Lusaka's Colonial Legacy: Town Planning, Public Health, And The Making Of A Segregated City, 1913–1963. A Study Of Power, Inequality, And Urban Development, Wamburakwao J. Sapao

Zambia Social Science Journal

This paper explores the intersection of town planning and public health policy in Lusaka, Northern Rhodesia (now Zambia), during the colonial period (1913–1963), which was a time of significant urban growth and transformation. British colonial authorities adapted Ebenezer Howard's Garden City principles to design and manage Lusaka, but these measures perpetuated spatial control, segregation, and social engineering, thus exacerbating racial and socio-economic disparities. By analysing secondary and primary sources, including planning ordinances, zoning regulations, and public health policies, this study reveals how these measures shaped the city's development and reinforced inequalities. Despite colonial intentions for a white settler-city, Lusaka evolved …

Measuring Spatial And Temporal Variation In Species Composition Of Ephemeral Pond Amphibian Assemblages Using Metabarcoding, Elizabeth Strasko

Masters Theses & Specialist Projects

Amphibian populations worldwide face severe threats, heightening the need for reliable monitoring methods. In this thesis, I explored and tested environmental DNA (eDNA) metabarcoding protocols to survey amphibian assemblages in ephemeral ponds of the the Green River Preserve in central Kentucky, USA. First, I evaluated whether the commonly used mitochondrial cytochrome c oxidase subunit I (COI) gene could effectively capture species-level variation in local amphibians for eDNA metabarcoding. Extensive primer design and testing revealed significant challenges in amplifying fragmented eDNA from water samples. In a second study, I applied a metabarcoding approach using the mitochondrial 12S ribosomal RNA (12S) gene …

Hispanic Paradox In Covid-19: Protective Effects Of Ethnic Density, Gregory Alan Urena

Theses and Dissertations

The COVID-19 pandemic exposed racial and ethnic health disparities in the U.S., with Hispanic populations experiencing higher infection and population-mortality rates than non-Hispanic Whites (NHW). Case fatality rates are closely tied to medical comorbidities such as hypertension, diabetes, and chronic kidney disease, which are more prevalent among Hispanic individuals. Case-fatality rates showed mixed results. Some studies found no differences, while others reported better outcomes for Hispanics, aligning with the Hispanic Paradox, which suggests that despite socioeconomic disadvantages, Hispanics experience equal or better health outcomes. These effects may be tied to the immigrant health advantage, which suggests immigrants tend to be …
