From Theory To Practice: Zoonotic Spillover, One Health And The Role Of Local Indigenous Communities, Pranav Prabhu Savanur Jan 2023

From Theory To Practice: Zoonotic Spillover, One Health And The Role Of Local Indigenous Communities, Pranav Prabhu Savanur

Public Health Theses

This paper discusses the impact of zoonotic spillovers on public health and the need for a One Health approach to preventing future pandemics. Zoonotic spillovers occur when pathogens are transmitted from animals to humans, facilitated by anthropogenic land changes, migration or trade, increased human-animal contact, and poor biosafety. However, anthropogenic land use change is the primary driver for zoonotic spillovers. Most emerging infectious diseases in humans are of zoonotic origin, and the impact of these spillovers on public health is significant. The paper emphasizes the need to prevent spillover events for primary pandemic prevention, which requires a coordinated and collaborative …

Compassion-Based Resilience Training (Cbrt) For Frontline Healthcare Workers In Contact With Covid-19 Patients, Michael Perez Sosa

Dissertations and Theses

Objectives: The COVID-19 pandemic has had deleterious consequences for the mental health of frontline healthcare workers worldwide. One systemic review of the literature found high prevalence rates of anxiety (67.55%), depression (58.89%), and stress (62.99%) reported by this population (Vizheh et al., 2020). Additionally, high rates of burnout and symptoms associated with trauma have also been ubiquitous during the pandemic for frontline healthcare workers. The purpose of this study is to investigate Compassion-Based Resilience Training (CBRT) as a remotely delivered intervention for frontline healthcare workers in contact with COVID-19 patients to reduce symptoms associated with stress, depression, anxiety, burnout, and …


The Nexus Of Climate Change And Human Rights: An Examination Of How Social, Political, And Environmental Impacts Of Climate Change Jeopardize The Protection Of Human Rights In The African Sahel, Camden R. Malone Jan 2023

The Nexus Of Climate Change And Human Rights: An Examination Of How Social, Political, And Environmental Impacts Of Climate Change Jeopardize The Protection Of Human Rights In The African Sahel, Camden R. Malone

Dissertations and Theses

Climate change is a threat multiplier by its driving forces of environmental stress and scarcity. In the developing world, countries are hit hardest and most frequently by the effects of climate change, such as severe floods, droughts, and desertification. In this thesis, I argue that existing models for the umbrella-term of climate-security underemphasize dimensions of human security through exclusion of HR violations linked to climate such as subjection to food/water stress, compromised health, displacement, and violent conflict. Therefore, the climate-security paradigm should be recast to pay closer attention to its consequences related to human rights protection, which I refer to …

Major Biotic Stresses Affecting Maize Production In Kenya And Their Implications For Food Security, Faith Njeri Njeru, Angeline Wambua, Edward Muge, Geert Haesaert, Jan Gettemans, Gerald Misinzo

All Rsif Scholars' Publications

Maize (Zea mays L.) is a staple food for many households in sub-Saharan Africa (SSA) and also contributes to the gross domestic product (GDP). However, the maize yields reported in most SSA countries are very low and this is mainly attributed to biotic and abiotic stresses. These stresses have been exacerbated by climate change which has led to long periods of drought or heavy flooding and the emergence of new biotic stresses. Few reports exist which compile the biotic stresses affecting maize production in SSA. Here, five major biotic stresses of maize in Kenya are presented which are attributed to …


Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne Jan 2023

Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne

UNF Graduate Theses and Dissertations

BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with …

School of Nursing and Midwifery

The worldwide spread of the COVID-19 disease has had a catastrophic effect on healthcare supply chains. The current manuscript systematically analyzes existing studies mitigating strategies for disruption management in the healthcare supply chain during COVID-19. Using a systematic approach, we recognized 35 related papers. Artificial intelligence (AI), block chain, big data analytics, and simulation are the most important technologies employed in supply chain management in healthcare. The findings reveal that the published research has concentrated mainly on generating resilience plans for the management of COVID-19 impacts. Furthermore, the vulnerability of healthcare supply chains and the necessity of establishing better resilience …


Immigrants Or Prostitutes? "White Slavery" Panics And Reform In France, England, And The United States, 1885-1915, Journey Steward Jan 2023

Immigrants Or Prostitutes? "White Slavery" Panics And Reform In France, England, And The United States, 1885-1915, Journey Steward

Graduate Research Theses & Dissertations

The late nineteenth century ushered in an era of global moral panic focusing on prostitution, venereal disease, and working-class female immigrants’ sexuality. By the early 1900s, European and American social reformers cooperated with national governments and immigration bureaus to stop “white slavery,” or the forced movement of white European and American women worldwide for purposes of commercial sex. This dissertation focuses on international trafficking in women and the ways in which accompanying moral panics developed from 1885 to 1915. It demonstrates how middle-class and nationalist assumptions about lower class sexuality, prostitution, and migration resulted in bourgeois social reform that influenced …


Discovery Of Acetyl Coa Synthetase And Sars-Cov-2 Protease Inhibitors, Taiwo Elijah Esan Jan 2023

Discovery Of Acetyl Coa Synthetase And Sars-Cov-2 Protease Inhibitors, Taiwo Elijah Esan

Graduate Research Theses & Dissertations

There is an urgent need for new antifungal drugs. Acetyl CoA synthetases (ACSs) are Acyl-CoA/NRPS/Luciferase (ANL) superfamily enzymes that couple acetate with CoA to generate acetyl CoA, a key component of central carbon metabolism in eukaryotes and prokaryotes. Normal mammalian cells are not dependent on ACSs, while tumor cells, fungi, and parasites rely on acetate as a precursor for acetyl CoA. Consequently, ACSs have emerged as a potential drug target. This body of work focuses on the inhibition of the Acetyl CoA synthetase enzyme in fungal species. This work has involved designing and synthesizing compounds that are potential fungal ACS1 …

Healthcare Provider Uncertainty And Communicative Management Strategies, Katie Benson Jan 2023

Healthcare Provider Uncertainty And Communicative Management Strategies, Katie Benson

Graduate Student Theses, Dissertations, & Professional Papers

Uncertainty exists ubiquitously within provider-patient interactions. Healthcare providers (HCPs) often face uncertainty during patient-provider interactions, for reasons including inconclusive test results, ambiguous communication, and lacking the resources to make diagnoses. When healthcare providers experience uncertainty, their behavior and communication can be negatively impacted. For example, prior research suggests when HCPs experience uncertainty, they may engage in authoritative, prejudiced and assumption-ridden behavior towards patients (Dietta & Rand, 2007; Drewniak et al., 2017: Portnoy et al., 2013; Poteat et al., 2013). To date, research on HCP uncertainty has been limited to specific health conditions and contexts such as cancer, vascular anomalies, and …


Mentoring Deep Learning Models For Mass Screening With Limited Data, Suprim Nakarmi Jan 2023

Mentoring Deep Learning Models For Mass Screening With Limited Data, Suprim Nakarmi

Dissertations and Theses

Deep Learning (DL) has an extensively rich state-of-the-art literature in medical imaging analysis. However, it requires large amount of data to begin training. This limits its usage in tackling future epidemics, as one might need to wait for months and even years to collect fully annotated data, raising a fundamental question: is it possible to deploy AI-driven tool earlier in epidemics to mass screen the infected cases? For such a context, human/Expert in the loop Machine Learning (ML), or Active Learning (AL), becomes imperative enabling machines to commence learning from the first day with minimum available labeled dataset. In an …

Percutaneous osseointegrated prostheses (POP) implants combat the multitude of issues and limitations of contemporary prosthetic sockets/limbs, including range of motion, comfort/fit, irritation, gait, and osseoproprioception. However, POP implants lack long-term clinical success; specifically, several risks exist at the bone-implant interface, including superficial/deep infections, inflammation, poor vascularization, and inadequate osseointegration, resulting in implant loosening over time and ultimately removal of the implant. The goal of this thesis is to evaluate a multifunctional, nitric oxide-releasing bionanomatrix incorporated with antibiotic-releasing liposomes on osseointegration, inflammation, vascularization/angiogenesis, and bacterial infection. We successfully synthesized the bionanomatrix, and the antibiotic-releasing liposomes readily encapsulated the antibiotics. The antibiotic-releasing …

Examining The Impact Of The Covid-19 Pandemic And Subsequent Vaccine Availability On Children’S Social Play Opportunities With A Focus On The Autism Community, Jenni Koehler

All ETDs from UAB

Play, especially social play, is crucial to child development and impacts their cognitive, socioemotional, and motor growth. Children with an autism spectrum disorder (ASD) have social and motor impairments that act as barriers to their access to these critical social play opportunities. Those who are able to overcome these barriers through therapy have been shown to have better physical and mental outcomes. Unfortunately, the COVID-19 pandemic restricted social play opportunities for all children and disproportionately impacted children with ASD, further widening developmental gaps between them and their non-autistic peers. The development of the COVID-19 vaccine and its availability to children …

The COVID-19 pandemic has inflicted profound challenges upon California, exacerbating disparities in care, access, and health outcomes within vulnerable and deprived communities. Especially, this crisis has led to a surge in mental health issues, with anxiety and depression emerging as predominant psychopathologies, and the rates of anxiety and depression are alarmingly high in disadvantaged communities. In California, the strikingly high prevalence of these symptoms at 31.7%, compared to the national average of 32.3%, sounds a critical alarm. Despite empirical investigations into anxiety and depression rates across a range of demographic groups worldwide—such as survivors, healthcare professionals, children, adolescents, and adults—the …

Lower respiratory infections are the primary cause of infectious death among the elderly. One reason for this is ‘inflamm-aging,’ a chronic low-grade inflammatory state that develops with advanced age. Pertinently, our group has shown increases in TNF levels to be responsible for age-dependent macrophage dysfunction (ADMD) and, in turn, enhanced susceptibility to Streptococcus pneumoniae, the leading cause of community-acquired pneumonia. The underlying molecular mechanisms responsible, however, remain unclear. Following adoptive transfer of alveolar macrophages (AM) from aged (18+ months) or young (3-6 month) mice into young mice, followed by infection with S. pneumoniae, we found that aged AM were sufficient …

The HIV care continuum is a public health model that outlines the steps or stages people with HIV go through from diagnosis to achieving and maintaining viral suppression. Retention in care, a key component of the HIV care continuum, is critical in achieving good health outcomes for people with HIV (PWH) and preventing HIV transmission. Consistent HIV care is essential for the health of PWH as a part of retention in care. De-spite no standard measure for retention in care to PWH, the missed (no-show) vis-its/appointments is one of the most commonly used methods for evaluating retention in HIV care. …

COVID-19 vaccine hesitancy and vaccine refusal contributed to many African Americans not receiving the COVID-19 vaccine. The reasons for vaccine hesitancy and vaccine refusal were unclear by sociodemographic factors (income, gender, education, and age) among African Americans. This research explored attitudes, subjective norms, and intent of COVID-19 vaccine hesitancy and vaccine refusal among African Americans in the United States using the Theory of Reasoned Action. The two research questions were (1) Among African Americans, do age, income, gender, and education factors remain stable across three study cohorts in differentiating subjects who are COVID-19 vaccine hesitant versus refusal from 2020–2022?

Genetic And Epigenetic Risk Scores For Chronic Kidney Disease In African Americans, Alana C. Jones Jan 2023

Genetic And Epigenetic Risk Scores For Chronic Kidney Disease In African Americans, Alana C. Jones

All ETDs from UAB

Kidney disease is the tenth-leading cause of death in the United States (US). There are significant racial disparities within kidney disease: African Americans (AAs) have the highest rates of CKD and carry a four-fold higher risk of developing end-stage renal disease (ESRD). They are also less likely to undergo kidney transplants, and among those who do, are more likely to experience graft rejection. Additionally, until 2021, kidney function equations were shown to underestimate the severity of kidney disease in AA due to the use of race coefficients. Among all populations, genetic and epigenetic factors contribute to kidney disease. However, AAs …

In late 2019, the emergence of COVID-19 in Wuhan, China, led to the implementation of stringent measures forming the zero-COVID policy aimed at eliminating transmission. Zero-COVID policy basically aimed at completely eliminating the transmission of COVID-19. However, the relaxation of this policy in late 2022 reportedly resulted in a rapid surge of COVID-19 cases. The aim of this work is to investigate the factors contributing to this outbreak using a new SEIR-type epidemic model with time-dependent level of immunity. Our model incorporates a time-dependent level of immunity considering vaccine doses administered and time-post-vaccination dependent vaccine efficacy. We find that vaccine …

INTRODUCTION: Immuno-oncology (IO) research relies heavily on murine syngeneic tumor models. However, whilst the average age for a cancer diagnosis is 60 years or older, for practical purposes the majority of preclinical studies are conducted in young mice, despite the fact that ageing has been shown to have a significant impact on the immune response.

METHODS: Using aged (60-72 weeks old) mice bearing CT26 tumors, we investigated the impact of ageing on tumor growth as well as the immune composition of the tumor and peripheral lymphoid organs.

RESULTS: We found many differences in the immune cell composition of both the …
