Understanding Hepatitis C Risk And Harm Reduction Needs Among People Who Smoke Drugs: A Client-Centered Qualitative Inquiry, Maxwell Gustin Dec 2025

Understanding Hepatitis C Risk And Harm Reduction Needs Among People Who Smoke Drugs: A Client-Centered Qualitative Inquiry, Maxwell Gustin

Anthropology

The spread of Hepatitis C virus (HCV) via non-injectable equipment is plausible, making people who smoke drugs (PWSD) at-risk for possible infection and transmission. While much research has been conducted into injection drug use (IDU), likely due to the rising opioid epidemic, limited studies focus on the risks PWSD face. Currently, state-funded syringe service programs (SSPs) provide harm reduction education and materials to combat these risks. Safer smoking initiatives have been created and are widely used by PWSD, and have access to SSPs. To gain better insight into the HCV and non-HCV-related risks and burdens PWSD face, a qualitative study …

House screening (HS) of doors, eaves, and windows using wire-mesh has demonstrated potential in the integrated vector management of malaria. However, limited epidemiological data are available to guide its implementation across different ecological settings. In a 16-month randomized controlled trial (follow-up period) conducted across three agroecological areas (dry mountain, plateau highland, and semi-arid) in Jabi Tehnan district, northwestern Ethiopia, treatment houses were equipped with HS combined with insecticide-treated nets (ITNs), while control houses received ITNs only. The intervention led to a significant 2.3-fold reduction in indoor malaria vector density, the primary entomologic outcome, largely influenced by An. gambiae s.l. mosquitoes. …

Public Health Trade-Offs During A Pandemic: Mobility Decline And Hypertension Risk In India, Arpita Khanna, Tomoki Fujii

Research Collection School Of Economics

The Covid pandemic dramatically altered patterns of daily life, particularly through widespread declines in mobility due to lockdowns and social distancing measures. While the economic and epidemiological effects of these restrictions have been widely studied, their broader health implications remain underexplored. This paper investigates the relationship between mobility decline during the Covid pandemic and hypertension outcomes in India. Leveraging district-level variation in mobility from Google Community Mobility Reports and health data from the 2019–2021 Indian Demographic and Health Survey (DHS), we find that a 1 percentage point reduction in mobility over the 30 days prior to interview is associated with …

‘In Texas, Everybody Wants Antibiotics’: Reducing Inappropriate Antibiotic Expectations And Use With A Provider-Patient Communication Tool In Primary Care, Ashley Collazo, Paige Wermuth, Johanan Luna Rodriguez, Kiara Olmeda, Azalia Mancera, Fabrizia Faustinella, Michael K Paasche-Orlow, Roger Zoorob, Barbara Wells Trautner, Larissa Grigoryan

Faculty, Staff and Students Publications

Background/objective: Patients often expect antibiotics for self-limiting diseases, pressuring providers to prescribe antibiotics unnecessarily. These expectations also contribute to the unsafe practice of taking antibiotics without a prescription (non-prescription use), such as pills retained from prior prescriptions or antibiotics from non-medical sources. Previous work shows that non-prescription use is due to strong, widely held misconceptions regarding the curative power of antibiotics. To reduce unnecessary use of antibiotics, we developed and pilot-tested a patient-focused, bilingual (English and Spanish) educational tool with patient and provider stakeholder input. The tool, a trifold brochure, included information on safe antibiotic use, potential antibiotic harms and …

Economics Faculty Articles and Research

During the COVID-19 pandemic, deaths per case in the United States decreased from 7.46% in April 2020 to 1.76% in April 2021. One mechanism that could explain this decline is a learning effect associated with testing of new treatments by hospitals. Hospitals that participated in clinical trials developed better organizational capabilities to diagnose and treat COVID-19 patients. Simultaneously, hospitals used health information technologies (IT) that integrated health information across healthcare providers to facilitate greater learning and sharing of best practices. Using US county-level data on clinical trial participation, use of health IT, and COVID-19 cases and deaths, we show that …

Kimmel Cancer Center Faculty Papers

Human T-cell leukemia virus type 1 (HTLV-1), the first oncogenic human retrovirus, causes adult T-cell leukemia/lymphoma (ATLL), an aggressive neoplasm of mature CD4+ T-cells that is incurable in most patients and is associated with a median survival of less than 1 year. HTLV-1 also causes inflammatory disorders, including HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and uveitis. The estimated lifetime risks of ATLL and HAM/TSP in HTLV-1 carriers are 3-5% and 0.25-1.8%, respectively. Although there is uncertainty about other health effects of HTLV-1, a recent meta-analysis showed an association between HTLV-1 and cardiovascular, cerebrovascular, and metabolic diseases and a 57% increased risk …


Curing The Peasant's Disease : Frank Oldt’S Work And Research On Hookworm Disease In South China, 1905-1926, Jiaying Fu Sep 2025

Curing The Peasant's Disease : Frank Oldt’S Work And Research On Hookworm Disease In South China, 1905-1926, Jiaying Fu

Lingnan Theses (MPhil & PhD)

While current scholarship on “hygienic modernity” in China focuses on the construction of urban health systems and institutional infrastructures, this study proposes an alternative analytical lens by foregrounding the domain of agricultural health. It aims to investigate how early twentieth-century medical researchers uncovered public health models grounded in China’s agrarian conditions. Taking the case of Frank Oldt (1879–1976), a medical missionary living in Guangdong between 1905 and 1926, this research examines how he identified, interpreted, and sought to mitigate the problem of hookworm disease—a parasitic condition intricately linked to China’s farming practices and rural environmental conditions.

Specifically, this thesis aims …

Modeling, Analysis, And Prediction Of Covid-19 Dynamics With Interacting Subpopulations And Implicit Behavior Using Physics-Informed Neural Networks, Naima Aubry-Romero, Alonso Ogueda-Oliva, Padmanabhan Seshaiyer

Spora: A Journal of Biomathematics

In this paper, we consider an extended SEIR compartmental model that incorporates young and old interacting subpopulations, allowing for cross-group transmission dynamics. Implicit behavioral changes are included to determine the influence of social behavior on coronavirus transmission dynamics. The basic reproduction number, the average number of secondary cases of infection produced by a single primary case, is derived for both the explicit and implicit model using the next-generation matrix method. We solve the associated differential equation systems and estimate useful parameters in the explicit model using physics-informed neural networks (PINNs). Our results point to how the PINNs approach offers an …

The Effect Of Individual Variation On Epidemiological Dynamics: From Super-Spreaders To Landscapes Of Risk, Alexis Shannon Beagle Jul 2025

The Effect Of Individual Variation On Epidemiological Dynamics: From Super-Spreaders To Landscapes Of Risk, Alexis Shannon Beagle

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Individuals that make up a population always display some level of variation between members. At the smallest scale, individuals always maintain genetic variation, but variation continues to arise at other scales of biological organization from physiological or immunological variation within individuals to variation in behavior between individuals that can be both genetically and environmentally mediated. The role of individual variation is particularly important in the context of infectious diseases because there is strong evidence that infections are highly heterogenous, indicating that patterns of individual variation drive a significant portion of the epidemiological patterns we observe. Individual variation leads to heterogeneity …
