Fitness Consequences Of Depressive Symptoms Vary Between Generations: Evidence From A Large Cohort Of Women Across The 20th Century, Christopher I Gurguis, Renée A Duckworth, Nicole M Bucaro, Consuelo Walss-Bass

Faculty, Staff and Student Publications

Depression has strong negative impacts on how individuals function, leading to the assumption that there is strong negative selection on this trait that should deplete genetic variation and decrease its prevalence in human populations. Yet, depressive symptoms remain common. While there has been a large body of work trying to resolve this paradox by mapping genetic variation of this complex trait, there have been few direct empirical tests of the core assumption that there is consistent negative selection on depression in human populations. Here, we use a unique long-term dataset from the National Health and Nutrition Examination Survey that spans …

Characterizing 4,4’-Methylene Diphenyl Diisocyanate Exposure In Primary Human Epidermal Keratinocytes: A Multi-Omics Approach, Brandon F. Law

Graduate Theses, Dissertations, and Problem Reports (ETD)

Exploring the routes of exposure and biological fate of 4,4’-methylene diphenyl diisocyanate (MDI) has been a challenge for many years. Occupational exposure to MDI can result in the development of occupational asthma (MDI-OA) which results in loss of productivity, large economic costs, and costs to the individual worker. Initially, it was thought that respiratory exposure to MDI was the most likely route leading to MDI-OA. Industries utilizing MDI have been successful at controlling airborne concentrations according to industrial hygiene assessment and newly diagnosed cases of MDI-OA decreased and plateaued. New research suggests that dermal exposures to MDI may explain this …

"Shut Down And Closed Off": A Routine Activity Approach To Investigating The Relationship Between Covid-19 School Closures And Child Sexual Abuse Report Characteristics In Georgia, Spencer E. Riner

College of Graduate Studies: Theses & Dissertations

The COVID-19 pandemic of 2020 created a public health crisis that led to an unprecedented number of school closures. A major concern raised by child advocates, law enforcement, and social service providers was the possible increase in undetected child abuse and maltreatment. Undergirding this concern was the belief that this mitigation effort might place child abuse victims and offenders within proximity for extended periods of time. While this was a significant concern, it has rarely been analyzed empirically. To address this gap in the literature, this thesis investigates how school closures impacted the characteristics of child sexual abuse (CSA) reports …

Factors Associated With Covid-19 Vaccine Hesitancy In South Central Appalachia, Florence M. Weierbach, Rebecca Adkins Fletcher, Ingrid E. Luffman, Cynthia Meyer, Janet M. Keener, Manik Ahuja, Hadii M. Mamudu

Journal of Appalachian Health

Introduction: The newly emergent COVID-19 virus reached pandemic levels in March 2020. By the middle of August 2020, there were over 1 million deaths attributed to COVID-19 in the U.S., with those in rural areas outpacing urban counterparts. Prior to emergency approval of the Pfizer, Moderna and Johnson & Johnson vaccine formulations, mitigation efforts addressing individual behavior were challenging. However, even with the entrance of these three new vaccines, herd immunity was not achieved in rural areas, as vaccine uptake remained low there. Although there has since been an abundance of COVID-19-related research addressing health literacy, vaccine hesitancy and overall …

People Are Less Myopic About Future Than Past Collective Outcomes, Markus Prior, Abdelaziz Alsharawy, Talbot M Andrews

Faculty, Staff and Student Publications

Myopia involves giving disproportionate weight to outcomes that occur close to the present. Myopia in people's evaluations of political outcomes and proposals threatens effective policymaking. It can lead to inefficient spending just before elections, cause inaction on important future policy challenges, and create incentives for government interventions aimed at boosting short-term performance at the expense of long-term welfare. But, are people generally myopic? Existing evidence comes mostly from studies that disregard either the future or collective outcomes. Political science characterizes people as myopic based on how they retrospectively evaluate collective outcomes, such as the state of the economy. Behavioral economics …

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1-11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common …

Parallel Neural Pathways Control Sodium Consumption And Taste Valence, Yameng Zhang, Allan-Hermann Pool, Tongtong Wang, Lu Liu, Elin Kang, Bei Zhang, Liang Ding, Kirsten Frieda, Richard Palmiter, Yuki Oka

Faculty, Staff and Student Publications

The hedonic value of salt fundamentally changes depending on the internal state. High concentrations of salt induce innate aversion under sated states, whereas such aversive stimuli transform into appetitive ones under sodium depletion. Neural mechanisms underlying this state-dependent salt valence switch are poorly understood. Using transcriptomics state-to-cell-type mapping and neural manipulations, we show that positive and negative valences of salt are controlled by anatomically distinct neural circuits in the mammalian brain. The hindbrain interoceptive circuit regulates sodium-specific appetitive drive , whereas behavioral tolerance of aversive salts is encoded by a dedicated class of neurons in the forebrain lamina terminalis (LT) …
