Snap And The School Meal Programs, Judith Bartfeld

University of Kentucky Center for Poverty Research Discussion Paper Series

The Great Recession and its immediate aftermath have brought increasing attention both to food insecurity among children and to the associated food safety net. After a decade of largely stable food insecurity rates, the share of children living in food insecure households jumped by one-third between 2007 and 2008, and has remained stubbornly high since then. As of 2012, 21.6% of all children lived in food insecure households (Coleman-Jensen et al. 2013). The scope and reach of the food safety net for children has likewise grown – a response to rising need, efforts to reduce administrative and logistical barriers to …

Truck Driver Dies When Tractor-Trailer Leaves The Road And Plunges Into A Creek-Bed, Kentucky Injury Prevention And Research Center

Fatality Case Reports--Motor Vehicle

In the early morning hours of a fall day, exact time unknown and the length of time driving unknown, a 28-year-old male truck driver was driving north on an interstate transporting 30,000 lbs. of blue plastic injection molding pellets. The truck driver exited the highway behind a guardrail and traveled 1,320 feet, striking a wire fence and several trees before plummeting into a creek bed, shearing the cab open. At 10:27 a.m., a citizen called in to the fire department to report a mysterious blue substance observed in the creek a couple of miles down from the accident. The fire …

Binding, Transcytosis And Biodistribution Of Anti-Pecam-1 Iron Oxide Nanoparticles For Brain-Targeted Delivery, Mo Dan, David B. Cochran, Robert A. Yokel, Thomas D. Dziubla

Pharmaceutical Sciences Faculty Publications

OBJECTIVE: Characterize the flux of platelet-endothelial cell adhesion molecule (PECAM-1) antibody-coated superparamagnetic iron oxide nanoparticles (IONPs) across the blood-brain barrier (BBB) and its biodistribution in vitro and in vivo.

METHODS: Anti-PECAM-1 IONPs and IgG IONPs were prepared and characterized in house. The binding affinity of these nanoparticles was investigated using human cortical microvascular endothelial cells (hCMEC/D3). Flux assays were performed using a hCMEC/D3 BBB model. To test their immunospecificity index and biodistribution, nanoparticles were given to Sprague Dawley rats by intra-carotid infusion. The capillary depletion method was used to elucidate their distribution between the BBB and brain parenchyma.

RESULTS: Anti-PECAM-1 …

A Process Similar To Autophagy Is Associated With Cytocidal Chloroquine Resistance In Plasmodium Falciparum, David Gaviria, Michelle F. Paguio, Lindsey B. Turnbull, Asako Tan, Amila Siriwardana, Debasish Ghosh, Michael T. Ferdig, Anthony P. Sinai, Paul D. Roepe

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Resistance to the cytostatic activity of the antimalarial drug chloroquine (CQ) is becoming well understood, however, resistance to cytocidal effects of CQ is largely unexplored. We find that PfCRT mutations that almost fully recapitulate P. falciparum cytostatic CQ resistance (CQR(CS)) as quantified by CQ IC50 shift, account for only 10-20% of cytocidal CQR (CQR(CC)) as quantified by CQ LD50 shift. Quantitative trait loci (QTL) analysis of the progeny of a chloroquine sensitive (CQS; strain HB3)×chloroquine resistant (CQR; strain Dd2) genetic cross identifies distinct genetic architectures for CQR(CS) vs CQR(CC) phenotypes, including identification of novel interacting chromosomal loci that influence CQ …

Evidence For Finely-Regulated Asynchronous Growth Of Toxoplasma Gondii Cysts Based On Data-Driven Model Selection, Adam M. Sullivan, Xiaopeng Zhao, Yasuhiro Suzuki, Eri Ochiai, Stephen Crutcher, Michael A. Gilchrist

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Toxoplasma gondii establishes a chronic infection by forming cysts preferentially in the brain. This chronic infection is one of the most common parasitic infections in humans and can be reactivated to develop life-threatening toxoplasmic encephalitis in immunocompromised patients. Host-pathogen interactions during the chronic infection include growth of the cysts and their removal by both natural rupture and elimination by the immune system. Analyzing these interactions is important for understanding the pathogenesis of this common infection. We developed a differential equation framework of cyst growth and employed Akaike Information Criteria (AIC) to determine the growth and removal functions that best describe …

Mice were fed a saturated fat-enriched diet for 1 week prior to pump implantation and during 4 weeks of infusion. Infusion of amlodipine resulted in plasma concentrations of 32 ± 2 ng/ml and 27 ± 2 ng/ml for mice in saline + amlodipine and AngII + …

Hrs Promotes Ubiquitination And Mediates Endosomal Trafficking Of Smoothened In Drosophila Hedgehog Signaling, Jun-Kai Fan, Kai Jiang, Yajuan Liu, Jianhang Jia

Markey Cancer Center Faculty Publications

In Hedgehog (Hh) signaling, the seven-transmembrane protein Smoothened (Smo) acts as a signal transducer that is regulated by phosphorylation, ubiquitination, and cell surface accumulation. However, it is not clear how Smo cell surface accumulation and intracellular trafficking are regulated. Here, we demonstrate that inactivation of Hrs by deletion or RNAi accumulates Smo in the late endosome that is marked by late endosome markers. Inactivation of Hrs enhances the wing defects caused by dominant-negative Smo. We show that Hrs promotes Smo ubiquitination, deleting the ubiquitin-interacting-motif (UIM) in Hrs abolishes the ability of Hrs to regulate Smo ubiquitination. However, the UIM domain …

New Health Delivery Networks: Merging Public Health And Health Care Systems, Glen P. Mays

Health Management and Policy Presentations

Incomplete coordination between medical care and public health delivery systems can result in significant missed opportunities for improving population health and constraining overall resource use. This lecture uses insight from the field of public health services and systems research (PHSSR) to examine: (1) why medical care and public health systems often fail to connect; (2) what are the potential health and economic consequences of these failures; and (3) what are the opportunities for connecting medical care and public health delivery to improve population health.

Recessions, Risks And Reforms: Changes In Inter-Organizational Activities To Improve Public Health, Glen P. Mays

Health Management and Policy Presentations

Research Objective: The Affordable Care Act created new incentives for hospitals, insurers, employers, public health agencies, and others to contribute to activities designed to promote health and prevent disease an injury. At the same time, the economic recession has constrained government and private sector spending on health and health care, necessitating changes in the scope and scale of public health delivery. This study uses data from the 1998-2012 National Longitudinal Survey of Public Health Systems to examine: (1) the extent and nature of change in inter-organizational contributions to public health activities, with a focus on hospitals, insurers, employers, and primary …

Who Benefits From Public Health Spending And How Long Does It Take: Estimating Community-Specific Spending Effects, Glen P. Mays

Health Management and Policy Presentations

Objectives: Spending on public health and prevention strategies varies widely across states and communities. The Patient Protection and Affordable Care Act of 2010 (ACA) authorized the largest expansion in federal public health spending in decades, with the goals of improving population health and helping to moderate growth in medical care spending. To produce evidence needed to inform these investments, this study (1) estimates the effects of public health spending patterns within communities on preventable mortality and subsequent medical care spending; and (2) uses the methods of local instrumental variables developed by Heckman and Vytlacil and Basu to estimate how the …

Background

Whether suicide attempters and completers represent the same population evaluated at different points along a progression towards suicide death, overlapping populations, or completely different populations is a problem still unresolved.

Methods

446 Adult suicide attempters and knowledgeable collateral informants for 190 adult suicide probands were interviewed. Sociodemographic and clinical data was collected for both groups using semi-structured interviews and structured assessments. Univariate analyses and logistic regression models were conducted to explore the similarities and differences between suicide attempters and completers.

Results

Univariate analyses yielded significant differences in sociodemographics, recent life events, impulsivity, suicide intent, and distribution of Axis I …

Nfkb Disrupts Tissue Polarity In 3d By Preventing Integration Of Microenvironmental Signals, Sabine Becker-Weimann, Gaofeng Xiong, Saori Furuta, Ju Han, Irene Kuhn, Uri-David Akavia, Dana Pe'er, Mina J. Bissell, Ren Xu

Markey Cancer Center Faculty Publications

The microenvironment of cells controls their phenotype, and thereby the architecture of the emerging multicellular structure or tissue. We have reported more than a dozen microenvironmental factors whose signaling must be integrated in order to effect an organized, functional tissue morphology. However, the factors that prevent integration of signaling pathways that merge form and function are still largely unknown. We have identified nuclear factor kappa B (NFkB) as a transcriptional regulator that disrupts important microenvironmental cues necessary for tissue organization. We compared the gene expression of organized and disorganized epithelial cells of the HMT-3522 breast cancer progression series: the non-malignant …

Epigenetic Dominance Of Prion Conformers, Eri Saijo, Hae-Eun Kang, Jifeng Bian, Kristi G. Bowling, Shawn Browning, Sehun Kim, Nora Hunter, Glenn C. Telling

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Although they share certain biological properties with nucleic acid based infectious agents, prions, the causative agents of invariably fatal, transmissible neurodegenerative disorders such as bovine spongiform encephalopathy, sheep scrapie, and human Creutzfeldt Jakob disease, propagate by conformational templating of host encoded proteins. Once thought to be unique to these diseases, this mechanism is now recognized as a ubiquitous means of information transfer in biological systems, including other protein misfolding disorders such as those causing Alzheimer's and Parkinson's diseases. To address the poorly understood mechanism by which host prion protein (PrP) primary structures interact with distinct prion conformations to influence pathogenesis, …

Mismatch Repair Genes Mlh1 And Mlh3 Modify Cag Instability In Huntington's Disease Mice: Genome-Wide And Candidate Approaches, Ricardo Mouro Pinto, Ella Dragileva, Andrew Kirby, Alejandro Lloret, Edith Lopez, Jason St. Claire, Gagan B. Panigrahi, Caixia Hou, Kim Holloway, Tammy Gillis, Jolene R. Guide, Paula E. Cohen, Guo-Min Li, Christopher E. Pearson, Mark J. Daly, Vanessa C. Wheeler

Toxicology and Cancer Biology Faculty Publications

The Huntington's disease gene (HTT) CAG repeat mutation undergoes somatic expansion that correlates with pathogenesis. Modifiers of somatic expansion may therefore provide routes for therapies targeting the underlying mutation, an approach that is likely applicable to other trinucleotide repeat diseases. Huntington's disease Hdh(Q111) mice exhibit higher levels of somatic HTT CAG expansion on a C57BL/6 genetic background (B6.Hdh(Q111) ) than on a 129 background (129.Hdh(Q111) ). Linkage mapping in (B6x129).Hdh(Q111) F2 intercross animals identified a single quantitative trait locus underlying the strain-specific difference in expansion in the striatum, implicating mismatch repair (MMR) gene Mlh1 as the most likely candidate modifier. …

Lpa, Hgf, And Egf Utilize Distinct Combinations Of Signaling Pathways To Promote Migration And Invasion Of Mda-Mb-231 Breast Carcinoma Cells, Susan M. W. Harrison, Teresa Knifley, Min Chen, Kathleen L. O'Connor

Markey Cancer Center Faculty Publications

BACKGROUND: Various pathways impinge on the actin-myosin pathway to facilitate cell migration and invasion including members of the Rho family of small GTPases and MAPK. However, the signaling components that are considered important for these processes vary substantially within the literature with certain pathways being favored. These distinctions in signaling pathways utilized are often attributed to differences in cell type or physiological conditions; however, these attributes have not been systematically assessed.

METHODS: To address this question, we analyzed the migration and invasion of MDA-MB-231 breast carcinoma cell line in response to various stimuli including lysophosphatidic acid (LPA), hepatocyte growth factor …

Preliminary Findings From An Interventional Study Using Network Analysis To Support Management In Local Health Departments In Florida, Chin S. Park, Hado Byon, Jonathan W. Keeling, Leslie M. Beitsch, Jacqueline A. Merrill

Frontiers in Public Health Services and Systems Research

Management is the core service that integrates and coordinates essential public health services. Managers of local health departments (LHDs) are experts in practice but may not have expertise in organizational management. We conducted an evidence-based training intervention in 10 LHDs in Florida to support managers’ decision-making on organizational integration and coordination. We deployed a standard survey to collect organizational network measurements pre and post intervention. We presented results as evidence-based performance feedback and interviewed managers to document how they used the results in the context of each organization. Post intervention we found unexpected, significantly higher network centralization in daily work. …

Characteristics Of A Local Health Department Associated With The Use Of The Health Equity Index, Moira A. Lawson, Sharon Mierzwa, Michael Knapp

Frontiers in Public Health Services and Systems Research

Local health departments are tasked with understanding and addressing health inequities in the populations they serve. To meaningfully address health inequities, local health departments have identified the need for credible local data to better understand the relationship between community conditions and health outcomes. Yet, when given access to these data, we observe a very large variation in the level of interest between local health departments.

In this study, we offered Connecticut’s Local health departments access to the Health Equity Index, a web based tool that provides data on health outcomes and community conditions at the state, municipal or neighborhood levels. …

Evaluating Use Of Custom Survey Reports By Local Health Departments, Nadya M. Belenky, Christine A. Bevc, Elizabeth Mahanna, Carol Gunther-Mohr, Mary V. Davis

Frontiers in Public Health Services and Systems Research

This report demonstrates how providing survey feedback, like comparative reports, to survey respondents can result in improvement activities. For each of the past three years (2010-2013), the North Carolina Institute for Public Health (NCIPH) has invited local health departments (LHDs) from 40 states to participate in a preparedness capacities survey. In addition, NCIPH fielded a six-question evaluation survey to a subset of LHDs (n=70) to determine how LHDs use these reports. LHDs that reported using their custom reports compared their preparedness capacities to other LHDs, conducted strategic planning (e.g., benchmarking, setting preparedness goals), planned staff trainings, and disseminated the report …
