The Tnfα-Transgenic Rat: Hippocampal Synaptic Integrity, Cognition, Function, And Post-Ischemic Cell Loss, L. Creed Pettigrew, Richard J. Kryscio, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

The cytokine, tumor necrosis factor α (TNFα), is a key regulator of neuroinflammation linked to numerous neurodegenerative conditions and diseases. The present study used transgenic rats that overexpress a murine TNFα gene, under the control of its own promoter, to investigate the impact of chronically elevated TNFα on hippocampal synaptic function. Neuronal viability and cognitive recovery in TNFα Tg rats were also determined following an ischemic insult arising from reversible middle cerebral artery occlusion (MCAO). Basal CA3-CA1 synaptic strength, recorded in acute brain slices, was not significantly different between eight-week-old TNFα Tg rats and non-Tg rats. In contrast, slices from …

African American Female Offender's Use Of Alternative And Traditional Health Services After Re-Entry: Examining The Behavioral Model For Vulnerable Populations, Carrie B. Oser, Amanda M. Bunting, Erin L. Pullen, Danelle Stevens-Watkins

Sociology Faculty Publications

This is the first known study to use the Gelberg-Andersen Behavioral Model for Vulnerable Populations to predict African American women's use of three types of health services (alternative, hospitalization, and ambulatory) in the 18 months after release from prison. In the multivariate models, the most robust predictors of all three types of service utilization were in the vulnerable theoretical domains. Alternative health services were predicted by ethnic community membership, higher religiosity, and HIV/HCV. Hospitalizations were predicted by the lack of barriers to health care and disability. Ambulatory office visits were predicted by more experiences of gendered racism, a greater number …

Understanding The Value Of Multi-Sector Partnerships To Improve Population Health, Glen P. Mays

Health Management and Policy Presentations

We review recent research concerning multi-sectoral partnerships aimed at improving health status on a population-wide basis, with a particular focus on implementation strategies and on health and economic impact. While still preliminary and emerging, research indicates that large health benefits are possible through collective actions that engage the medical, public health, and social sectors. Mechanisms for aligning incentives, dividing responsibilities equitably, and measuring progress regularly appear critical to success.

Phantom Limb Pain, Stephanie J. Stockburger, Mandakini Sadhir, Hatim A. Omar

Pediatrics Faculty Publications

Phantom limb pain is pain that is perceived in a part of the body which is no longer present. It is estimated that 80 percent of amputees experience phantom limb pain. Although the term is “phantom limb pain” the feeling is often more of a burning, twisting, itching, or pressure sensation than pain. The exact mechanism of phantom limb pain is unknown although proposed mechanisms include pain origination from either the central nervous system or the peripheral nervous system. Since the exact mechanism of phantom limb pain is unknown, treating this pain may be difficult. Treatments include pharmacological and nonpharmacological. …

Similarities And Differences In Sexual Risk Behaviors Between Young Black Msm Who Do And Do Not Have Sex With Females, Richard A. Crosby, Leandro Mena, Angelica Geter, Demarc Hickson

Health, Behavior & Society Faculty Publications

The objective of this study is to determine whether young Black MSM who also have sex with females report similar levels of sexual risk behaviors as those not having sex with females. YBMSM (N = 400) were recruited from an STI clinic, located in the Southern U.S. Men completed an audio-computer assisted self-interview and donated specimens for STI/HIV testing. Forty-three percent recently engaged in penile-vaginal sex. They were less likely to report having concurrent partners (P = .01), unprotected fellatio (P = .04), multiple partners as a bottom (P < .02), any unprotected anal sex as a bottom (P < .013), and any anal sex (P = .007). They were equally likely …

Integrating Health Services & Systems: What We Know, Think We Know, And Need To Learn, Glen P. Mays

Health Management and Policy Presentations

The delivery and financing systems for medical care, public health, and social and community services pursue many common goals and serve overlapping groups of families and communities. Unfortunately, in most American communities these systems interact in complex and often poorly understood ways through fragmented funding vehicles, information flows, governance and decision-making structures, institutional relationships, implementation rules and strategies, and professional and interpersonal connections. New research approaches are required to untangle these interactions and expose novel pathways of influence that can support equitable improvements in service delivery, resource use, health impact, and wellbeing. This presentation will summarize evidence from recent studies …

Smith, Justin Peng, Michael J. Bauer, Ming Qu, Denise Yeager, Timothy Kerns, Cynthia Burch, Lawrence J. Cook

Biostatistics Faculty Publications

Background: Despite evidence that motorcycle helmets reduce morbidity and mortality, helmet laws and rates of helmet use vary by state in the U.S.

Methods: We pooled data from eleven states: five with universal laws requiring all motorcyclists to wear a helmet, and six with partial laws requiring only a subset of motorcyclists to wear a helmet. Data were combined in the Crash Outcome Data Evaluation System's General Use Model and included motorcycle crash records probabilistically linked to emergency department and inpatient discharges for years 2005-2008. Medical outcomes were compared between partial and universal helmet law settings. We estimated adjusted relative …

Measuring Multi-Sector Contributions To Public Health Delivery Systems & Population Health, Glen P. Mays

Health Management and Policy Presentations

The National Longitudinal Survey of Public Health Systems has followed a nationally-representative cohort of U.S. communities since 1998 to measure the scope of public health activities implemented in each community and the range of organizations and sectors that contribute to each activity. With 16 years of follow-up observations, this survey allows us to study the effects of demographic, economic, and policy shocks on public health delivery systems, and estimate the health effects attributable to delivery system change.

Decreasing Obesity And Obesity Stigma: Socio-Demographic Differences In Beliefs About Causes Of And Responsibility For Obesity, Christy F. Brady

Sociology Faculty Publications

Obesity is a stigmatized condition, and research has shown that obesity stigma varies based on the perceived cause of obesity. It is important that public health professionals develop policy and campaigns that resonate with specific populations while avoiding an increase in harmful stigma. This study identifies socio-demographic differences in causal attributions of obesity and beliefs about responsibility for obesity. Using data from a survey of 923 people in the United States conducted by ABC New/Time Magazine, attributions of cause and responsibility are analyzed using Ordinary Least Squares regression. Beliefs about cause and responsibility fall on a continuum from primarily individual …

Colorectal Cancer Prevention: Perspectives Of Key Players From Social Networks In A Low-Income Rural Us Region, Nancy E. Schoenberg, Kathryn Eddens, Adam Jonas, Claire Snell-Rood, Christina R. Studts, Benjamin Broder-Oldach, Mira L. Katz

Behavioral Science Faculty Publications

Social networks influence health behavior and health status. Within social networks, “key players” often influence those around them, particularly in traditionally underserved areas like the Appalachian region in the USA. From a total sample of 787 Appalachian residents, we identified and interviewed 10 key players in complex networks, asking them what comprises a key player, their role in their network and community, and ideas to overcome and increase colorectal cancer (CRC) screening. Key players emphasized their communication skills, resourcefulness, and special occupational and educational status in the community. Barriers to CRC screening included negative perceptions of the colonoscopy screening procedure, …

Evidence For The Role Of Resource-Sharing Networks In Coalition Development, Margaret Mcgladrey, Angela Carman Drph

Frontiers in Public Health Services and Systems Research

Background: Accreditation bodies and sponsors of community health projects increasingly require the use of health coalitions in community health planning efforts to ensure buy-in, leverage resources, and distribute health information. Despite a substantive body of research documenting the characteristics of successful health coalitions, little is known about how team dynamics in these coalitions evolve.

Purpose: The goal of this study was to employ social network analysis techniques to evaluate whether coalitions’ relative stages in Tuckman’s stages of team development model were associated with specific patterns of advice-, information-, and resource-sharing among the eight coalitions participating in a region-wide …

A Pilot Test Of A Mobile App For Drug Court Participants, Kimberly Johnson, Stephanie Richards, Ming-Yuan Chih, Tae Joon Moon, Hilary Curtis, David H. Gustafson

Health and Clinical Sciences Faculty Publications

The U.S. criminal justice system refers more people to substance abuse treatment than any other system. Low treatment completion rates and high relapse rates among addicted offenders highlight the need for better substance use disorder treatment and recovery tools. Mobile health applications (apps) may fill that need by providing continuous support. In this pilot test, 30 participants in a Massachusetts drug court program used A-CHESS, a mobile app for recovery support and relapse prevention, over a four-month period. Over the course of the study period, participants opened A-CHESS on average of 62% of the days that they had the app. …

Mw151 Inhibited Il-1Β Levels After Traumatic Brain Injury With No Effect On Microglia Physiological Responses, Adam D. Bachstetter, Zhengqiu Zhou, Rachel K. Rowe, Bin Xing, Danielle S. Goulding, Alyssa N. Conley, Pradoldej Sompol, Shelby Meier, Jose F. Abisambra, Jonathan Lifshitz, D. Martin Watterson, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

A prevailing neuroinflammation hypothesis is that increased production of proinflammatory cytokines contributes to progressive neuropathology, secondary to the primary damage caused by a traumatic brain injury (TBI). In support of the hypothesis, post-injury interventions that inhibit the proinflammatory cytokine surge can attenuate the progressive pathology. However, other post-injury neuroinflammatory responses are key to endogenous recovery responses. Therefore, it is critical that pharmacological attenuation of detrimental or dysregulated neuroinflammatory processes avoid pan-suppression of inflammation. MW151 is a CNS-penetrant, small molecule experimental therapeutic that restores injury- or disease-induced overproduction of proinflammatory cytokines towards homeostasis without immunosuppression. Post-injury administration of MW151 in a …

AΒ40 Reduces P-Glycoprotein At The Blood-Brain Barrier Through The Ubiquitin-Proteasome Pathway, Anika M. S. Hartz, Yu Zhong, Andrea Wolf, Harry Levine Iii, David S. Miller, Björn Bauer

Sanders-Brown Center on Aging Faculty Publications

Failure to clear amyloid-β (Aβ) from the brain is in part responsible for Aβ brain accumulation in Alzheimer's disease (AD). A critical protein for clearing Aβ across the blood–brain barrier is the efflux transporter P-glycoprotein (P-gp) in the luminal plasma membrane of the brain capillary endothelium. P-gp is reduced at the blood–brain barrier in AD, which has been shown to be associated with Aβ brain accumulation. However, the mechanism responsible for P-gp reduction in AD is not well understood. Here we focused on identifying critical mechanistic steps involved in reducing P-gp in AD. We …

Behavioral Science Faculty Publications

β-amyloid (Aβ) plaques and tau-related neurodegeneration are pathologic hallmarks of Alzheimer’s disease (AD). The utility of AD biomarkers, including those measured in cerebrospinal fluid (CSF), in predicting future AD risk and cognitive decline is still being refined. Here, we explored potential relationships between functional connectivity (FC) patterns within the default-mode network (DMN), age, CSF biomarkers (Aβ₄₂ and pTau₁₈₁), and cognitive status in older adults. Multiple measures of FC were explored, including a novel time series-based measure [total interdependence (TI)]. In our sample of 27 cognitively normal older adults, no significant associations were found between levels of Aβ …

Factors Associated With Unmet Needs Among African-American Dementia Care Providers, P. J. Desin, Allison M. Caban-Holt, Erin L. Abner, Linda J. Van Eldik, Frederick A. Schmitt

Sanders-Brown Center on Aging Faculty Publications

Racial and ethnic minorities currently comprise 20% of the U.S. population; in 2050, this figure is expected to rise to 42%. As a result, Alzheimer’s disease (AD), the 5th leading cause of death for people aged 65 and older, is likely to increase in these groups. Most dementia caregiving for these populations comes from family and friends, especially among families with lower socioeconomic status. A convenience sample of 30 African-American dementia caregivers was interviewed to determine unmet needs. Participants expressed a limited desire for formal services, such as support groups, legal advice, case management, and homemaker services. Instead, commonly expressed …

Pathological Tau Promotes Neuronal Damage By Impairing Ribosomal Function And Decreasing Protein Synthesis, Shelby Meier, Michelle Bell, Danielle N. Lyons, Jennifer Rodriguez-Rivera, Alexandria Ingram, Sarah N. Fontaine, Elizabeth Mechas, Jing Chen, Benjamin Wolozin, Harry Levine Iii, Haining Zhu, Jose F. Abisambra

Sanders-Brown Center on Aging Faculty Publications

One of the most common symptoms of Alzheimer's disease (AD) and related tauopathies is memory loss. The exact mechanisms leading to memory loss in tauopathies are not yet known; however, decreased translation due to ribosomal dysfunction has been implicated as a part of this process. Here we use a proteomics approach that incorporates subcellular fractionation and coimmunoprecipitation of tau from human AD and non-demented control brains to identify novel interactions between tau and the endoplasmic reticulum (ER). We show that ribosomes associate more closely with tau in AD than with tau in control brains, and that this abnormal association leads …

Is There A Trade-Off? Infant Health Outcomes And Managed Care Competition, Shana L. Moore

Theses and Dissertations--Public Policy and Administration

This study offers insights into the impact of competition among Managed Care organizations (MCOs) on infant birthing charges and birth outcomes. Kentucky provides one of the nation’s first case studies to determine successes and failures of Medicaid MCOs, and by doing so, provides a prediction of the impact of Patient Protection Affordable Care Act (PPACA) competition on healthcare costs and birth outcomes. An analysis of a natural policy experiment in the state of Kentucky reveals that infants insured by a Medicaid MCO stay longer in hospitals, are less healthy, and cost more than those insured under Traditional Medicaid prior to …

Making Health A Priority: Constrained Choices At The Grocery Store, Christy F. Brady

Theses and Dissertations--Sociology

Mounting evidence of the deleterious health effects of poor diet, obesity, and correlated conditions underscore the need to understand how social factors influence food choices. A variety of factors contribute to the diets that Americans consume including limited time, limited income, lack of cooking skills, food deserts, and cheap, convenient foods in abundant portions in grocery stores and restaurants. These contextual factors serve as constraints that impact an individual’s ability to prioritize health when shopping for food. Using the three paper dissertation format, this project will utilize a Constrained Choice Theory (CCT) framework to investigate sociodemographic trends in priorities in …
