BACKGROUND: The course of Alzheimer's disease (AD) includes a 10-20-year preclinical period with progressive accumulation of amyloid β (Aβ) plaques and neurofibrillary tangles in the absence of symptomatic cognitive or functional decline. The duration of this preclinical stage in part depends on the rate of pathologic progression, which is offset by compensatory mechanisms, referred to as cognitive reserve (CR). Comorbid medical conditions, psychosocial stressors, and inappropriate medication use may lower CR, hastening the onset of symptomatic AD. Here, we describe a randomized controlled trial (RCT) designed to test the efficacy of a medication therapy management (MTM) intervention to reduce inappropriate …

Partial Psychiatric Hospitalization Program Availability In Non-Metropolitan And Metropolitan Hospitals Nationally, Timothy Williams, Tyrone F. Borders, Lindsey Jasinski

Rural & Underserved Health Research Center Publications

Overview of Key Findings

Partial psychiatric hospitalization programs (PPHPs) are intended to reduce or avoid inpatient stays by allowing patients to reside at home while receiving intensive psychiatric services in outpatient settings.

A significantly smaller proportion of non-metropolitan than metropolitan hospitals offer PPHPs.

• 11.4% of non-metropolitan compared to 38.7% of metropolitan hospitals offer PPHPs.
• Regardless of location, hospitals that offer PPHPs have higher patient volumes and more beds than hospitals that offer PPHPs through affiliated providers or do not offer PPHPs at all.

Both short and long sleep are associated with an adverse lipid profile, likely through different biological pathways. To elucidate the biology of sleep-associated adverse lipid profile, we conduct multi-ancestry genome-wide sleep-SNP interaction analyses on three lipid traits (HDL-c, LDL-c and triglycerides). In the total study sample (discovery + replication) of 126,926 individuals from 5 different ancestry groups, when considering either long or short total sleep time interactions in joint analyses, we identify 49 previously unreported lipid loci, and 10 additional previously unreported lipid loci in a restricted sample of European-ancestry cohorts. In addition, we identify new gene-sleep interactions for known …

Understanding Lung Cancer Resources And Barriers Among Worksites With Mostly Male Employees In Eight Rural Kentucky Counties: A Focus Group Discussion, Jennifer Redmond Knight, Lucy Hollingsworth Williamson, Debra K. Armstrong, Elizabeth A. Westbrook

Health Management and Policy Faculty Publications

Kentucky has the highest cancer incidence and mortality rates in the United States, and lung cancer is Kentucky's leading cause of cancer deaths. Males in Kentucky have higher lung incidence and mortality rates than females. Through support from the SelfMade Health Network, Kentucky developed a Regional Resource Lead Organization that collaboratively developed a multi-component worksite intervention on lung cancer among male populations. The intervention targets eight Kentucky counties. The first component and focus of this manuscript included focus group meetings with organizational representatives in each county that provide health, educational, and social services to men and worksites. The focus groups …

Hospital Closures And Short-Run Change In Ambulance Call Times, Sookti Chaudhary, Alison F. Davis, Kenneth R. Troske, Suzanne Troske

Rural & Underserved Health Research Center Publications

We measure one aspect of how access to emergency care through ambulance services changes for patients when a hospital closes. We empirically estimate the time needed to transport a patient to an emergency department in an ambulance in the period immediately after the hospital closes. We find urban patients in zip codes where a hospital closes have a small change in transportation time, where rural patients average an estimated 15.7 additional minutes – a 46% increase compared to the year before the closure. This increase is primarily the result of an almost 100 percent increase in the time it takes …

Post-Acquisition Processing Confounds In Brain Volumetric Quantification Of White Matter Hyperintensities, Ahmed A. Bahrani, Omar M. Al-Janabi, Erin L. Abner, Shoshana H. Bardach, Richard J. Kryscio, Donna M. Wilcock, Charles D. Smith, Gregory A. Jicha

Neurology Faculty Publications

BACKGROUND: Disparate research sites using identical or near-identical magnetic resonance imaging (MRI) acquisition techniques often produce results that demonstrate significant variability regarding volumetric quantification of white matter hyperintensities (WMH) in the aging population. The sources of such variability have not previously been fully explored.

NEW METHOD: 3D FLAIR sequences from a group of randomly selected aged subjects were analyzed to identify sources-of-variability in post-acquisition processing that can be problematic when comparing WMH volumetric data across disparate sites. The methods developed focused on standardizing post-acquisition protocol processing methods to develop a protocol with less than 0.5% inter-rater variance.

RESULTS: A series …

Enhancing Timeliness Of Drug Overdose Mortality Surveillance: A Machine Learning Approach, Patrick J. Ward, Peter J. Rock, Svetla Slavova, April M. Young, Terry L. Bunn, Ramakanth Kavuluru

Kentucky Injury Prevention and Research Center Faculty Publications

BACKGROUND: Timely data is key to effective public health responses to epidemics. Drug overdose deaths are identified in surveillance systems through ICD-10 codes present on death certificates. ICD-10 coding takes time, but free-text information is available on death certificates prior to ICD-10 coding. The objective of this study was to develop a machine learning method to classify free-text death certificates as drug overdoses to provide faster drug overdose mortality surveillance.

METHODS: Using 2017–2018 Kentucky death certificate data, free-text fields were tokenized and features were created from these tokens using natural language processing (NLP). Word, bigram, and trigram features were created …

Why We Can’T Solve The Opioid Problem, Wayne F. Coombs, Ph.D.

Journal of Appalachian Health

Appalachia’s opioid epidemic is a complex, systemic problem being addressed by limited intervention processes conceptualized through narrow disciplinary models that are not working. We need a new comprehensive, collaborative approach if we ever hope to find solutions to this problem.

A Virginia Mountain City Responds To The Challenge Of Improving Health Outcomes, Robert S. Cowell Jr.

Journal of Appalachian Health

In 2012, Roanoke Virginia was becoming a city of haves and have-nots, a place where many were benefitting from revitalization underway but too many were seeing their situation grow worse and becoming even more entrenched. Poverty with levels as high as 50% in some neighborhoods; life expectancy sometimes 14 years shorter than those living just one or two neighborhoods over; and lack of access to fresh food, medical care, and economic opportunities—all within view of the largest hospital in the region was unacceptable.

Adult Food Security And The Relationship With Adverse Childhood Experiences Among Residents Of Appalachian North Carolina, Manan Roy, Erin Bouldin, Maggie Bennett, Adam Hege

Journal of Appalachian Health

Introduction: The Appalachian region has worse health outcomes than the remainder of the United States. These disparities are often linked to the underlying social and environmental determinants of health. Adverse childhood experiences (ACEs) are associated with poor health outcomes across the lifespan and have a significant impact on future social determinants as an adult, including food security status.

Purpose: To explore the relationships between ACEs and food security among adults in the Appalachian counties of North Carolina and make comparisons with the rest of the state.

Methods: Researchers used North Carolina’s 2012 Behavioral Risk Factor Surveillance System data; namely, …

A Comparison Of Appalachian And Non-Appalachian Kentucky Dui Offenders, Megan F. Dickson, Megan Kissel, J. Matthew Webster

Journal of Appalachian Health

Background: Driving under the influence has been an overlooked consequence of the opioid epidemic. Although recent reports have highlighted the increased prevalence of DUI in rural communities and the extensive mental health problems and criminal and drug use histories among rural Appalachian DUI offenders, it is unclear how Appalachian DUI populations compare to DUI offenders in other regions.

Purpose: To help fill this void in the literature, the current study uses a statewide sample to examine how Appalachian DUI offenders differ from non-Appalachian DUI offenders in a predominantly rural state.

Methods: Assessment records were examined for 11,640 Kentucky DUI offenders …

Roanoke's Collective Public Health Activities, Michael Lytton

Journal of Appalachian Health

Roanoke is addressing problems that confront many small and medium sized cities in the U.S., especially disparities in health and life expectancy between neighborhoods. These disparities are often legacies of decades of racial and economic segregation, resulting in low-income or disinvested communities. Typically, such neighborhoods have fewer parks, higher vacancy rates and less stable affordable housing stock, inadequate public transit systems, too few clinics, too many fast food restaurants and insufficient access to high quality schools. In Roanoke these are the northwest and southeast quadrants, both federally designated Medically Underserved Areas, and characterized by a large proportion of the city’s …

Metformin Blunts Muscle Hypertrophy In Response To Progressive Resistance Exercise Training In Older Adults: A Randomized, Double‐Blind, Placebo‐Controlled, Multicenter Trial: The Masters Trial, R. Grace Walton, Cory M. Dungan, Douglas E. Long, S. Craig Tuggle, Kate Kosmac, Bailey D. Peck, Heather M. Bush, Alejandro G. Villasante Tezanos, Gerald Mcgwin, Samuel T. Windham, Fernando Ovalle, Marcas M. Bamman, Philip A. Kern, Charlotte A. Peterson

Center for Muscle Biology Faculty Publications

Progressive resistance exercise training (PRT) is the most effective known intervention for combating aging skeletal muscle atrophy. However, the hypertrophic response to PRT is variable, and this may be due to muscle inflammation susceptibility. Metformin reduces inflammation, so we hypothesized that metformin would augment the muscle response to PRT in healthy women and men aged 65 and older. In a randomized, double-blind trial, participants received 1,700 mg/day metformin (N = 46) or placebo (N = 48) throughout the study, and all subjects performed 14 weeks of supervised PRT. Although responses to PRT varied, placebo gained more lean body …

The Effects Of Opioids On Kentucky's Workforce, Michael W. Clark, Jenny A. Minier, Charles J. Courtemanche, Bethany L. Paris, Michael T. Childress

CBER Research Report

From the executive summary:

Opioid abuse represents a significant and growing public health issue for both the nation and Kentucky. In 2016, opioids contributed to more than 62,000 deaths nationally and 1,406 deaths in Kentucky. National studies have placed the societal costs of opioid abuse at $55.7 billion in 2007 and $78.5 billion in 2013 (Birbaum et al. (2011) and Florence et al. (2016)). These costs included increased health care expenditures, higher criminal justice costs, and lost earnings due to reduced employment and premature deaths. The While House Council of Economic Advisors (2017) estimated the societal costs of opioid abuse …

The Effect Of Smoking On Kentucky’S Workforce, Michael W. Clark, Jenny A. Minier, Charles J. Courtemanche, Bethany L. Paris, Michael T. Childress

CBER Research Report

Excerpt from the Executive Summary:

Smoking has been estimated to increase health care costs in the United States by $167.5 billion annually (Xu et al. 2015). In Kentucky, smoking adds $2.5 billion in health care expenditures each year. Most of these costs were paid by public programs such as Medicaid and Medicare. While these costs are significant, they represent only a portion of the costs that smoking imposes on society. Smoking also leads to poorer labor market outcomes. Smokers are more likely to be unemployed, earn lower wages, and die prematurely than non-smokers. These negative labor market effects reduce economic …

The Medicalization Of Sleeplessness: Results Of U.S. Office Visit Outcomes, 2008-2015, Mairead Eastin Moloney, Gabriele Ciciurkaite, Robyn Lewis Brown

Sociology Faculty Publications

Previous analysis of U.S. physician office visits (1993–2007) indicated that the medicalization of sleeplessness was on the rise and had potentially negative implications for population health. Our study asks if the medicalization of sleeplessness at the level of patient-physician interaction has persisted over time. Using the most recent years available (2008–2015) of the National Ambulatory Medical Care Survey we calculated nationally representative estimates for four sleeplessness-related outcomes of physician office visits: sleeplessness complaint, insomnia diagnosis, and prescription of benzodiazepine and non-benzodiazepine sedative-hypnotics (NBSH). To test for the significance of the linear trajectory, we ran a series of bivariate linear models. …

A Legacy Of Disease, Arthur L. Frank

Journal of Appalachian Health

In Appalachia, like much of America, there are important health issues that have not always been appropriately predicted or dealt with when they occur. Lifestyle issues in Appalachia lead to obesity and heart disease, not surprisingly due to extensive use of sugary drinks. The current opioid crisis could have been better predicted given the trauma of mining and the past abuse of less-potent narcotics. A continuing major problem in the whole country is inadequate support for preventive health activities.

Using Mini-Grants To Build Multi-Sector Partnerships In Rural Tennessee, Ginny Kidwell, Kristine Bowers, Taylor M. Dula, Randolph F. Wykoff

Journal of Appalachian Health

Rural counties in Tennessee, including those located in Appalachia, face some of the greatest health challenges in the nation. Unpublished data collated by the East Tennessee State University College of Public Health (ETSU) show that Tennessee’s 52 Appalachian counties vary dramatically from its 43 non-Appalachian counties in virtually all socioeconomic, behavioral, and health outcome metrics. Since 2011, the Tennessee Institute of Public Health (TNIPH) has actively encouraged local communities to address behavior change, enhance educational achievement, and improve economic conditions as essential components for improving health and well-being in rural Tennessee.

Disparities In Quality Of Life By Appalachian-Designation Among Women With Breast Cancer, Robin C. Vanderpool, Ann L. Coker, Heather M. Bush, Sarah E. Cprek

Journal of Appalachian Health

Introduction: Few studies have examined the association of geography and quality of life (QOL) among breast cancer patients, particularly differences between Appalachian and non-Appalachian Kentucky women, which is important given the cancer and socioeconomic disparities present in Appalachia.

Purpose: The purpose of this study was to determine whether women with breast cancer residing in Appalachian Kentucky experience poorer health outcomes in regards to depression, stress, QOL, and spiritual wellbeing, relative to those living in non-Appalachian Kentucky after adjusting for demographic, socioeconomic, and health-related factors.

Methods: Women, aged 18–79, recruited from the Kentucky Cancer Registry between 2009 and 2013 with an …

Social Media Use Among Nonprofit Organizations In Rural Appalachia, Mckenzie Liegel, Jodi L. Southerland, Katie Baker

Journal of Appalachian Health

Introduction: Social media have changed the landscape of health communication for nonprofit organizations (NPOs). Yet, adoption and use of social media lag among NPOs in rural Appalachia due largely to limited infrastructure development.

Methods: Semi-structured phone interviews were conducted in January–March 2018 with 21 NPO representatives in an 8-county region of rural Appalachian Tennessee. NPO representatives were asked questions pertaining to social media use and message content, effective communication strategies, and best practices in social media use. Transcripts were analyzed in April–May 2018 using thematic analysis.

Results: The majority of NPOs had a Facebook page and recognized its …

Barriers To Healthy Eating Among High School Youth In Rural Southern Appalachia, Jodi L. Southerland, Taylor M. Dula, Deborah L. Slawson

Journal of Appalachian Health

Introduction: Diet and nutrition play an important role in a child’s health and reduce the risk of numerous health problems including obesity. Dietary habits can be difficult to modify in children, particularly in Appalachia, where access to affordable, healthy foods is limited.

Purpose: To examine barriers to healthy eating among Appalachian youth.

Methods: In 2013–2014, data were gathered via focus groups and interviews from parents, school personnel, and adolescents (N=99) in six counties across southern Appalachia. Data were analyzed using thematic network analysis. Analysis was completed in 2015.

West Virginia’S Sugary Drink Tax: Examining Print Media Frames In Local News Sources, Lauri Andress, Ogaga Urhie, Christine Compton

Journal of Appalachian Health

Introduction: Framing is an important aspect of the policy process that helps the public and decision makers sort through and resolve highly charged claims about an issue. Through slight changes in the presentation of issues, a framing effect may alter public support. The way a proposed sugary drink tax is discussed in public discourse and by the media significantly influences policy acceptance. Given the public health significance of obesity and diabetes in West Virginia (WV) the study of media frames employed to represent a sugary drink tax policy is useful.

Methods: Using quantitative content analysis, this study assessed news articles—published …

Root Causes Of Appalachia’S Deaths Of Despair, F. Douglas Scutchfield Md

Journal of Appalachian Health

The U.S. is experiencing a decline in life expectancy, particularly among rural white males in their most productive years. Appalachia is disproportionally represented in mortality rates, accounting for 30% of the U.S. population, but 50% of the excess mortality attributed to the “deaths of despair”: drug overdose, suicide, and alcoholic cirrhosis. A substantial proportion of that excess mortality is related to the current opioid crisis we are experiencing. We have data on evidence-based solutions to the treatment of addiction, but little information on prevention of addiction as well as the other deaths of despair, likely with the same etiologic agent. …

The Role Of The Community Health Delivery System In The Health And Well-Being Of Justice-Involved Women: A Narrative Review, Sharla A. Smith, Glen P. Mays, Tracie C. Collins, Megha Ramaswamy

Health Management and Policy Faculty Publications

Background: Over seven million imprisoned and jailed women are released into the community each year and many are ill-equipped to meet the challenges of re-integration. Upon release into their community, women are faced with uncertain barriers and challenges using community services to improve their health and well-being and reuniting with families. Few studies have identified and described the barriers of the community health delivery system (CHDS)- a complex set of social, justice, and healthcare organizations that provide community services aimed to improve the health and well-being (i.e. safety, health, the success of integration, and life satisfaction) of justice-involved women. We …
