Sugihara Causality Analysis Of Scalp Eeg For Detection Of Early Alzheimer's Disease, Joseph C. Mcbride, Xiaopeng Zhao, Nancy B. Munro, Greg A. Jicha, Frederick A. Schmitt, Richard J. Kryscio, Charles D. Smith, Yang Jiang

Sanders-Brown Center on Aging Faculty Publications

Recently, Sugihara proposed an innovative causality concept, which, in contrast to statistical predictability in Granger sense, characterizes underlying deterministic causation of the system. This work exploits Sugihara causality analysis to develop novel EEG biomarkers for discriminating normal aging from mild cognitive impairment (MCI) and early Alzheimer's disease (AD). The hypothesis of this work is that scalp EEG based causality measurements have different distributions for different cognitive groups and hence the causality measurements can be used to distinguish between NC, MCI, and AD participants. The current results are based on 30-channel resting EEG records from 48 age-matched participants (mean age 75.7 …

Amyloid beta (Abeta) 1-42 oligomers accumulate in brains of patients with Mild Cognitive Impairment (MCI) and disrupt synaptic plasticity processes that underlie memory formation. Synaptic binding of Abeta oligomers to several putative receptor proteins is reported to inhibit long-term potentiation, affect membrane trafficking and induce reversible spine loss in neurons, leading to impaired cognitive performance and ultimately to anterograde amnesia in the early stages of Alzheimer's disease (AD). We have identified a receptor not previously associated with AD that mediates the binding of Abeta oligomers to neurons, and describe novel therapeutic antagonists of this receptor capable of blocking Abeta toxic …

Alzheimer's Therapeutics Targeting Amyloid Beta 1-42 Oligomers I: Abeta 42 Oligomer Binding To Specific Neuronal Receptors Is Displaced By Drug Candidates That Improve Cognitive Deficits, Nicholas J.

Synaptic dysfunction and loss caused by age-dependent accumulation of synaptotoxic beta amyloid (Abeta) 1-42 oligomers is proposed to underlie cognitive decline in Alzheimer's disease (AD). Alterations in membrane trafficking induced by Abeta oligomers mediates reduction in neuronal surface receptor expression that is the basis for inhibition of electrophysiological measures of synaptic plasticity and thus learning and memory. We have utilized phenotypic screens in mature, in vitro cultures of rat brain cells to identify small molecules which block or prevent the binding and effects of Abeta oligomers. Synthetic Abeta oligomers bind saturably to a single site on neuronal synapses and induce …

Reassessing The Effects Of Unemployment Insurance Generosity On Search Intensity: New Evidence From Earnings Histories, Lewis Warren

University of Kentucky Center for Poverty Research Discussion Paper Series

This paper provides the first nationally representative estimates of how unemployment insurance (UI) generosity in the United States affects the search intensity of unemployed individuals using individual level variation in UI generosity. The paper expands the current literature through fully simulating monetary eligibility and entitlement to unemployment insurance at the individual level where past studies have been unable to examine monetary eligibility and have relied on state variations in the maximum weekly benefit amount which can differ significantly from an individual’s actual benefit amount. To simulate monetary eligibility and entitlement, work histories of unemployed respondents were obtained through fully matching …

The P38alpha Mitogen-Activated Protein Kinase Limits The Cns Proinflammatory Cytokine Response To Systemic Lipopolysaccharide, Potentially Through An Il-10 Dependent Mechanism, Adam D. Bachstetter, Bin Xing, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: The p38α mitogen-activated protein kinase (MAPK) is a well-characterized intracellular kinase involved in the overproduction of proinflammatory cytokines from glia. As such, p38α appears to be a promising therapeutic target for neurodegenerative diseases associated with neuroinflammation. However, the in vivo role of p38α in cytokine production in the CNS is poorly defined, and prior work suggests that p38α may be affecting a yet to be identified negative feedback mechanism that limits the acute, injury-induced proinflammatory cytokine surge in the CNS.

METHODS: To attempt to define this negative feedback mechanism, we used two in vitro and two in vivo models …

Self-Reported Memory Complaints: Implications From A Longitudinal Cohort With Autopsies, Richard J. Kryscio, Erin L. Abner, Gregory E. Cooper, David W. Fardo, Greg A. Jicha, Peter T. Nelson, Charles D. Smith, Linda J. Van Eldik, Lijie Wan, Frederick A. Schmitt

Sanders-Brown Center on Aging Faculty Publications

OBJECTIVE: We assessed salience of subjective memory complaints (SMCs) by older individuals as a predictor of subsequent cognitive impairment while accounting for risk factors and eventual neuropathologies.

METHODS: Subjects (n = 531) enrolled while cognitively intact at the University of Kentucky were asked annually if they perceived changes in memory since their last visit. A multistate model estimated when transition to impairment occurred while adjusting for intervening death. Risk factors affecting the timing and probability of an impairment were identified. The association between SMCs and Alzheimer-type neuropathology was assessed from autopsies (n = 243).

RESULTS: SMCs were …

Examining The Associations Of Racism, Sexism, And Stressful Life Events On Psychological Distress Among African-American Women, Danelle Stevens-Watkins, Brea Perry, Erin L. Pullen, Jennifer Jewell, Carrie B. Oser

Educational, School, and Counseling Psychology Faculty Publications

African-American women may be susceptible to stressful events and adverse health outcomes as a result of their distinct social location at the intersection of gender and race. Here, racism and sexism are examined concurrently using survey data from 204 African-American women residing in a southeastern U.S. urban city. Associations among racism, sexism, and stressful events across social roles and contexts (i.e., social network loss, motherhood and childbirth, employment and finances, personal illness and injury, and victimization) are investigated. Then, the relationships among these stressors on psychological distress are compared, and a moderation model is explored. Findings suggest that racism and …

OBJECTIVE: Informal caregivers (family and friends) of people with cancer are often unprepared for their caregiving role, leading to increased burden or distress. Comprehensive Health Enhancement Support System (CHESS) is a Web-based lung cancer information, communication, and coaching system for caregivers. This randomized trial reports the impact on caregiver burden, disruptiveness, and mood of providing caregivers access to CHESS versus the Internet with a list of recommended lung cancer websites.

METHODS: A total of 285 informal caregivers of patients with advanced nonsmall cell lung cancer were randomly assigned to a comparison group that received Internet or a treatment group that …

Con: Are We Ready To Translate Alzheimer's Disease-Modifying Therapies To People With Down Syndrome?, Elizabeth Head, Frederick A. Schmitt

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Adults with Down syndrome develop Alzheimer's disease neuropathology in an age-dependent manner. This unique feature provides an opportunity to test interventions targeted for prevention of Alzheimer's disease neuropathology and dementia in Down syndrome.

DISCUSSION: In considering clinical trial designs, however, there are several challenges that we believe will be critical to examine further. These include: accuracy in dementia, mild cognitive impairment and preclinical Alzheimer's disease diagnoses in Down syndrome; clinical trial outcome measures appropriate for individuals with Down syndrome; in vivo imaging outcome measures (and practical considerations); and contributions of medical co-morbidities to disease progression. Also, when studies are …

Calcineurin And Glial Signaling: Neuroinflammation And Beyond, Jennifer L. Furman, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

Similar to peripheral immune/inflammatory cells, neuroglial cells appear to rely on calcineurin (CN) signaling pathways to regulate cytokine production and cellular activation. Several studies suggest that harmful immune/inflammatory responses may be the most impactful consequence of aberrant CN activity in glial cells. However, newly identified roles for CN in glutamate uptake, gap junction regulation, Ca²⁺ dyshomeostasis, and amyloid production suggest that CN's influence in glia may extend well beyond neuroinflammation. The following review will discuss the various actions of CN in glial cells, with particular emphasis on astrocytes, and consider the implications for neurologic dysfunction arising with aging, injury, …

Paternal Incarceration And Children's Food Insecurity: A Consideration Of Variation And Mechanisms, Kristen Turney

University of Kentucky Center for Poverty Research Discussion Paper Series

Despite growing attention to the unintended consequences of paternal incarceration for children’s wellbeing across the life course, little is known about whether and how paternal incarceration is related to food insecurity among children, an especially acute and severe form of deprivation. In this article, I use data from the Fragile Families and Child Wellbeing Study, a cohort of children born to mostly unmarried mothers, to examine the relationship between paternal incarceration and three indicators of food insecurity among young children: current food insecurity (at age five), onset of food insecurity (between ages three and five), and exit from food insecurity …

Childhood Stress: A Qualitative Analysis Of The Intergenerational Circumstances Of Child Hunger, Mariana Chilton, Molly Knowles

University of Kentucky Center for Poverty Research Discussion Paper Series

Adverse Childhood Experiences (ACEs), including abuse, neglect, and household instability, affect lifelong health and economic potential. While relationships between household food insecurity and caregiver’s childhood exposure to abuse and neglect are underexplored, preliminary evidence indicates that caregivers reporting very low food security report traumatic events in their childhoods that lead to poor physical and mental health. Building on this evidence, this study investigates how adverse childhood experiences are associated with the intergenerational transmission of household food insecurity.

Distributional Effects Of Welfare Reform Experiments: A Panel Quantile Regression Examination, Carlos Lamarche, Robert Paul Hartley

University of Kentucky Center for Poverty Research Discussion Paper Series

In an influential article, Bitler, Gelbach and Hoynes (American Economic Re- view, 2006; 96, 988-1012) illustrate the importance of estimating heterogeneous impacts of welfare reform experiments. They find that the mean treatment effect offers an uninfor- mative summary of opposing effects, while the treatment effects are significantly different across quantiles. We replicate their results and evaluate the robustness of their findings to accounting for individual-specific heterogeneity possibly associated with welfare program participation. We find results that are in general similar to Bitler’s et al. findings, although the interpretation of labor supply effects in the upper tail is revised. We find …

Transition From An M1 To A Mixed Neuroinflammatory Phenotype Increases Amyloid Deposition In App/Ps1 Transgenic Mice, Erica M. Weekman, Tiffany L. Sudduth, Erin L. Abner, Gabriel J. Popa, Michael D. Mendenhall, Holly M. Brothers, Kaitlyn Braun, Abigail Greenstein, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: The polarization to different neuroinflammatory phenotypes has been described in early Alzheimer's disease, yet the impact of these phenotypes on amyloid-beta (Aβ) pathology remains unknown. Short-term studies show that induction of an M1 neuroinflammatory phenotype reduces Aβ, but long-term studies have not been performed that track the neuroinflammatory phenotype.

METHODS: Wild-type and APP/PS1 transgenic mice aged 3 to 4 months received a bilateral intracranial injection of adeno-associated viral (AAV) vectors expressing IFNγ or green fluorescent protein in the frontal cortex and hippocampus. Mice were sacrificed 4 or 6 months post-injection. ELISA measurements were used for IFNγ protein levels and …

Democratizing The Food System- The Food Policy Council Movement, Garrett Spear

Kaleidoscope

The increasing complexity of our modern food system has changed the landscape of American agriculture and diet, and has increasingly consolidated decision-making abilities in a concentrated group of organizations. Local food movements are re-appropriating their food supply chains through a variety of methods, including the democratic-minded food policy council organization. Food policy councils organize community stakeholders into a network of organizations which can collectively grapple with food issues affecting and on behalf of the local community. This study consisted of research on the history and methods of the food policy council movement, directed ultimately at the council-less context in Lexington …

An Exploration Of Sexual Victimization And Academic Performance Among College Women, Carol E. Jordan, Jessica L. Combs, Gregory T. Smith

Office for Policy Studies on Violence Against Women Publications

The literature has documented the widespread nature of sexual assault victimization among college women. While the aftermath of violence against university women has also received focus, that is, documenting trauma-related sequelae; risk factors; reporting patterns; and legal interventions, the impact on academic performance has not received adequate attention in the literature. The primary purpose of this study was to explore the association of rape and sexual assault with academic performance among college women. Its specific aims included the following: to compare high school and college sexual assault experiences with collegiate grade point averages (GPAs) at key points in time; to …

Obesity And Diabetes Cause Cognitive Dysfunction In The Absence Of Accelerated Β-Amyloid Deposition In A Novel Murine Model Of Mixed Or Vascular Dementia, Dana M. Niedowicz, Valerie L.

Larson, Sabire Özcan, Christopher M. Norris, Louis B. Hersh, Nada M. Porter, Donna M. Wilcock, Michael Paul Murphy

Sanders-Brown Center on Aging Faculty Publications

Mid-life obesity and type 2 diabetes mellitus (T2DM) confer a modest, increased risk for Alzheimer's disease (AD), though the underlying mechanisms are unknown. We have created a novel mouse model that recapitulates features of T2DM and AD by crossing morbidly obese and diabetic db/db mice with APP^ΔNL/ΔNLx PS1^P264L/P264L knock-in mice. These mice (db/AD) retain many features of the parental lines (e.g. extreme obesity, diabetes, and parenchymal deposition of β-amyloid (Aβ)). The combination of the two diseases led to additional pathologies-perhaps most striking of which was the presence of severe cerebrovascular pathology, including aneurysms and small …

Screening For Ipv In Formal And Informal Settings, Nancy Glass, Elizabeth Miller

NSF-NIJ IPV Prevention Workshop

Overview

Within the last 20 years, gender-based violence (GBV) has gained increased attention globally. GBV is defined as types of violence that primarily women/girls experience, including physical violence (e.g., hitting, punching, kicked, slapped, choked, hurt with a weapon, or otherwise physically hurt), sexual violence (e.g. unprotected forced sex, coercive behaviors, including sexual slavery and coerced abortion), and psychological harm (e.g. controlling behaviors, stalking, threats of violence). These acts of violence are perpetrated by members of women/girl’s family, acquaintances, and/or strangers in the home, community and/or during armed conflict. Globally, an estimated 35% of women experience physical and/or sexual violence in …

Effects Of Maternal Depression On Family Food Insecurity, Kelly Noonan, Hope Corman, Nancy E. Reichman

University of Kentucky Center for Poverty Research Discussion Paper Series

Theory suggests that adverse life events—such as unemployment or health shocks—can result in food insecurity, which has increased substantially in the U.S. over the past decade alongside the obesity epidemic. We test this proposition by estimating the effects of a specific and salient mental health event—maternal depression during the postpartum year—on child and family food insecurity. Using data from the Early Childhood Longitudinal Study—Birth Cohort, we estimate the effects of maternal depression on food insecurity using both single- and twostage models, and explore potential buffering effects of relevant public assistance programs and supports. We find that moderate to severe maternal …
