Establishing a Rural General Surgery Residency Program: Identifying Community Stakeholder Perception and Obstacles of a de Novo Residency in Rural Appalachia

BACKGROUND

Rural healthcare has become more challenging over the past several years with increasingly limited access to surgical care in the rural setting. The Accreditation Council for Graduate Medical Education (ACGME) has recently introduced the Rural Track Program (RTP) initiative to combat physician shortage in rural areas. We intend to start the first Rural General Surgery Residency program under the RTP designation in rural Appalachia.

STUDY DESIGN

430 community stakeholders were surveyed regarding the anticipated impact of a new training program. Questions focused on the understanding of a Residency Program, the care provided by residents, impact on availability of local care, current geographical limitation of surgical care, and potential benefits/obstacles of the training program.

RESULTS

Over 90% of all surveyed approved of training surgeons locally, with the local government believing that the program would be a good investment for the community. Several locals had been treated by resident physicians at other facilities and the majority were satisfied with the care they received. Several families frequently travel to larger cities for surgical care, with 96% of all respondents believing that the program would provide better access to care locally.

CONCLUSION

Our study demonstrated that the community is familiar with healthcare in a training facility and welcoming to a local training program, while believing that trainees will have a positive impact on local surgical care in rural Appalachia. We will continue to work with the local community and healthcare personnel while developing the program and tailor our Residency to the rural setting as able.

Covid and the coalfield: Covid-19 vaccine hesitance in Wales and Appalachia

BACKGROUND

Vaccine hesitancy is a barrier to Covid-19 vaccine uptake and displays a social gradient, compounding health disparities. While social gradients are a vital concept in health, they flatten distinctions between types of disadvantaged community. This paper focuses on vaccine hesitance in post-industrial and de-industrialising coalfields. The social consequences of the decline of coal mining may present barriers to vaccine uptake.

METHODS

We ran parallel surveys in Wales (N = 4187) and US states overlapping with central Appalachia (N = 4864), to examine whether vaccine attitudes and uptake varied between areas with different coal mining histories. These surveys were accompanied by qualitative interviews of 36 residents of these coalfields to explore vaccination decisions and triangulate with survey data.

RESULTS

Factor analysis identified four axes of attitudes in the survey data: vaccine confidence, covid scepticism, vaccine individualism, and concerned confusion. These themes were echoed in the interviews. Vaccine confidence was lower; and covid scepticism, vaccine individualism, and concerned confusion higher, in residents of areas of Wales with greater mining extent and where pits closed during certain periods. Residents of former US coal counties had lower vaccine confidence and higher covid scepticism, while those in current coal counties had greater vaccine individualism and concerned confusion. In former US coal counties and Welsh areas where pits closed since 1980, vaccine uptake was lower. Differences could not be explained by respondents' income and education. In the interviews, norms of social solidarity were often invoked by vaccinated respondents, while unvaccinated respondents did not frame decisions in the context of the industrial history of their areas.

DISCUSSION

The legacy of coal-mining's decline presents barriers to public health campaigns. We show evidence of this across two historically significant coalfields. Attention is needed to avert negative public health consequences of global energy transition.

Molecular phylogeography and historical demography of a widespread herbaceous species from eastern North America, Podophyllum peltatum

PREMISE

Glacial/interglacial cycles and topographic complexity are both considered to have shaped today's diverse phylogeographic patterns of taxa from unglaciated eastern North America (ENA). However, few studies have focused on the phylogeography and population dynamics of wide-ranging ENA herbaceous species occurring in forest understory habitat. We examined the phylogeographic pattern and evolutionary history of Podophyllum peltatum L., a widely distributed herb inhabiting deciduous forests of ENA.

METHODS

Using chloroplast DNA (cpDNA) sequences and nuclear microsatellite loci, we investigated the population structure and genetic diversity of the species. Molecular dating, demographic history analyses, and ecological niche modeling were also performed to illustrate the phylogeographic patterns.

RESULTS

Our cpDNA results identified three main groups that are largely congruent with boundaries along the Appalachian Mountains and the Mississippi River, two major geographic barriers in ENA. Populations located to the east of the Appalachians and along the central Appalachians exhibited relatively higher levels of genetic diversity. Extant lineages may have diverged during the late Miocene, and range expansions of different groups may have happened during the Pleistocene glacial/interglacial cycles.

CONCLUSIONS

Our findings indicate that geographic barriers may have started to facilitate the population divergence in P. peltatum before the Pleistocene. Persistence in multiple refugia, including areas around the central Appalachians during the Quaternary glacial period, and subsequent expansions under hospitable climatic condition, especially westward expansion, are likely responsible for the species' contemporary genetic structure and phylogeographic pattern.

Perceptions of oral nicotine pouches & their marketing among Ohio Appalachia smokers and smokeless tobacco users

BACKGROUND

Oral nicotine pouches (ONPs) are novel products, gaining popularity and marketed as "tobacco-free" alternatives to cigarettes and smokeless tobacco (SLT), but their public health impact is unknown. This study qualitatively examined ONP appeal and perceptions among cigarette smokers and SLT users from Ohio Appalachia.

METHODS

In 2022, we conducted 10 virtual focus groups with smokers (n = 19) and smokeless tobacco users (n = 18) from Appalachia Ohio aged ≥21 to examine perceptions of risks and benefits, substitutability for cigarettes and SLT, and ONP marketing. We transcribed focus groups verbatim, thematically coded transcripts, and analyzed coded data for prominent themes.

RESULTS

Participants perceived ONPs to have similar or less risk than cigarettes/SLT but prominently discussed gastrointestinal and cardiovascular risks. Addiction risk was thought to be comparable to cigarettes/SLT, citing "nicotine is nicotine." Participants viewed ONPs to be situational rather than complete substitutes for cigarettes/SLT, viewing them as "cleaner," more socially acceptable, and discrete. Despite appealing features of ONP marketing, participants surmised ads would appeal to youth, new users, tobacco users seeking to cut down/quit, or to "high class," "white-collar" demographics.

CONCLUSIONS

Participants' perceptions of ONPs and their marketing suggest ONPs are more likely to be used as situational versus complete substitutes for cigarettes and SLT. While situational substitution could exacerbate disparities in Appalachia by facilitating more frequent tobacco/nicotine use, complete substitution could reduce disparities. Research is needed to understand how perceptions, the appeal of ONP marketing, and novel product features translate to patterns of use to understand ONPs' potential impact.

System Failure: The Geographic Distribution of Sepsis-Associated Death in the USA and Factors Contributing to the Mortality Burden of Black Communities

Sepsis is deadly and costly to health care systems, but these costs are disproportionately born by Black patients. Little empirical work has established the geographic patterning of sepsis or its area-level correlates. This study illustrates the geography of sepsis-associated death and racial composition of US counties with area socioeconomic indicators, health care access, and population health. Cartographic and spatially explicit analyses utilize mortality data from the National Cancer Institute and county data from the American Community Survey, Area Health Resource File, and County Health Rankings. Death rates are highest in the South, Southeast, and Appalachia. Counties disproportionately populated by Black people have higher death rates and associated risk indicators including poor air quality and vaccination coverage, socioeconomic distress, and impaired access to high-quality health care. Spatial Durbin error models suggest that conditions in nearby counties may also influence death rates within focal counties. Racial disparities in sepsis-associated death can be narrowed with improved health care equity-including immunization coverage-and by reducing socioeconomic distress in Black communities. Policy options for achieving these ends are discussed.

Contraceptive Behavior in Appalachia: Exploring Use, Nonuse, and Contraceptive Attitudes

Very little is known about contraceptive behavior in Appalachia, a large geographic region in the eastern United States where even basic prevalence estimates of contraceptive use/nonuse are lacking. This study characterizes contraceptive behavior among Appalachians, including contraceptive use, reasons for use, and methods used; contraceptive nonuse and reasons for nonuse; and attitudes about contraception, including acceptability. This is a secondary analysis of a subsample of survey data collected on sexual and reproductive health attitudes, behaviors, and needs among reproductive-age women (18-49 years) living in the Appalachian region (n = 332). Results identify rates of contraceptive use (66.6%) and nonuse (33.1%) among Appalachian residents. Methods used most frequently included those that did not require prescription (i.e., external condoms and natural family planning methods) though many reported the use of intrauterine devices (IUDs). Among nonusers, fear of side effects from contraception and ambivalence towards pregnancy were most commonly selected as the most important reason for not using contraception. Contraception was considered acceptable by this sample overall, and these acceptability attitudes were significantly associated with contraceptive behavior.

Biogeography and the evolution of acoustic communication in the polyploid North American grey treefrog complex

After polyploid species are formed, interactions between diploid and polyploid lineages may generate additional diversity in novel cytotypes and phenotypes. In anurans, mate choice by acoustic communication is the primary method by which individuals identify their own species and assess suitable mates. As such, the evolution of acoustic signals is an important mechanism for contributing to reproductive isolation and diversification in this group. Here, we estimate the biogeographical history of the North American grey treefrog complex, consisting of the diploid Hyla chrysoscelis and the tetraploid Hyla versicolor, focusing specifically on the geographical origin of whole genome duplication and the expansion of lineages out of glacial refugia. We then test for lineage-specific differences in mating signals by applying comparative methods to a large acoustic data set collected over 52 years that includes >1500 individual frogs. Along with describing the overall biogeographical history and call diversity, we found evidence that the geographical origin of H. versicolor and the formation of the midwestern polyploid lineage are both associated with glacial limits, and that the southwestern polyploid lineage is associated with a shift in acoustic phenotype relative to the diploid lineage with which they share a mitochondrial lineage. In H. chrysoscelis, we see that acoustic signals are largely split by Eastern and Western lineages, but that northward expansion along either side of the Appalachian Mountains is associated with further acoustic diversification. Overall, results of this study provide substantial clarity on the evolution of grey treefrogs as it relates to their biogeography and acoustic communication.

State-Level History of Overdose Deaths Involving Stimulants in the United States, 1999‒2020

Objectives. To examine the state-level history of US overdose deaths involving stimulants with and without opioids from 1999 to 2020. Methods. We used death certificate data from the National Center for Health Statistics to categorize deaths into 4 groups of interest: cocaine with and without opioids, and psychostimulants with and without opioids. We used a Bayesian multiple change point model to describe the timing and magnitude of changes in overdose death rates involving stimulants for each state and year. Results. There was little change in the death rates of cocaine without opioids. Death rates involving cocaine and opioids sharply increased around 2015, particularly in the Northeast and Mid-Atlantic. We also observed steady increases in deaths involving psychostimulants without opioids just before 2010, particularly in states in the West and South. Deaths involving psychostimulants with opioids increased around 2015 with largest increases concentrated in Appalachian states. Conclusions. There is significant geographic heterogeneity in the co-involvement of stimulants in the US overdose crisis. Results can inform public health efforts to inform state-level overdose efforts such as naloxone distribution. (Am J Public Health. 2023;113(9):991-999. https://doi.org/10.2105/AJPH.2023.307337).

White-tailed deer (Odocoileus virginianus) fawn survival and the influence of landscape characteristics on fawn predation risk in the Southern Appalachian Mountains, USA

In the Southern Appalachian region of the United States, harvest data has indicated the occurrence of low deer densities while exposing a trend of declining white-tailed deer (Odocoileus virginianus) populations over the past several decades in northern Georgia. A triumvirate of increasing fawn predator populations reside in the Southern Appalachian Mountains including coyotes (Canis latrans), black bears (Ursus americanus) and bobcats (Lynx rufus). This region is also characterized by a homogenous landscape composed of mature forests and sparse understory vegetation, likely lacking adequate cover to offer fawns refugia from predators. Our objectives were to estimate survival and cause-specific mortality rates of fawns while assessing a possible link between mortality risk, intrinsic fawn characteristics (i.e., birth mass, Julian birth date, sibling status), and landscape features within fawn usage areas. During 2018-2020, we radio-collared 71 fawns within the Chattahoochee National Forest of northern Georgia, USA and monitored survival to 12 weeks of age. We observed low fawn survival (cumulative = 0.157, 95% CI = 0.091-0.273; vaginal implant transmitter = 0.196, 95% CI = 0.096-0.403) with predation as the leading cause of all known mortalities (45 of 55 mortalities; 82%) due primarily to coyotes (n = 22), black bears (n = 12), and bobcats (n = 7). Relationships between landscape features and fawn predation risk were minimal with only one informative covariate. Increasing amounts of early successional land cover within fawn usage areas decreased fawn mortality risk within the first 20 days of life, but elevated mortality risk thereafter. All fawns with any amount of early successional land cover in their usage areas died of predation (n = 13) at various time intervals, suggesting limited areas of potential fawning cover may be targeted by predators. However, fawn predation risk seemed to be high regardless of landscape covariates due to the limited number of surviving fawns. Coyote-caused mortality occurred over a longer period at a consistently higher magnitude than all other forms of mortality, indicating possible delayed prey-switching behavior and coyote predation as an important factor of fawn survival. The low recruitment of fawns influenced by high predation rates and homogenous habitat conditions is likely the cause of deer population declines in the region.

Progress in reducing cancer mortality in the United States by congressional district, 1996-2003 to 2012-2020

BACKGROUND

United States cancer death rates have been steadily declining since the early 1990s, but information on disparities in progress against cancer mortality across congressional districts is lacking. This study examined trends in cancer death rates, overall and for lung, colorectal, female breast, and prostate cancer by congressional district.

METHODS

County level cancer death counts and population data from the National Center for Health Statistics were used to estimate relative change in age-standardized cancer death rates from 1996-2003 to 2012-2020 by sex and congressional district.

RESULTS

From 1996-2003 to 2012-2020, overall cancer death rates declined in every congressional district, with most congressional districts showing a 20%-45% decline among males and a 10%-40% decline among females. In general, the smallest percent of relative declines were found in the Midwest and Appalachia, whereas the largest declines were found in the South along the East Coast and the southern border. As a result, the highest cancer death rates generally shifted from congressional districts across the South in 1996-2003 to districts in the Midwest and central divisions of the South (including Appalachia) in 2012-2020. Death rates for lung, colorectal, female breast, and prostate cancers also declined in almost all congressional districts, although with some variation in relative changes and geographical patterns.

CONCLUSIONS

Progress in reducing cancer death rates during the past 25 years considerably vary by congressional district, underscoring the need for strengthening existing and implementing new public health policies for broad and equitable application of proven interventions such as raising tax on tobacco and Medicaid expansion.

Vaccination intention and uptake within the Black community in Appalachia

OBJECTIVE

Black communities have disproportionately experienced adverse health effects from the COVID-19 pandemic while simultaneously having less vaccination access and decreased vaccine utilization. As such, predictors of vaccination uptake within Black communities are a public health imperative. Black Americans from socio-geographic regions associated with health inequities (e.g., Appalachia), including vaccination disparities, represent an intersection of racial, economic, and ethnic social identities. To better understand the preventive health needs of Black communities in Appalachia and elsewhere, this study examined psychosocial predictors of vaccination intention or behavior.

METHOD

Adults (n = 336) identifying as Black or African American from West Virginia indicated demographics, reported COVID-19 vaccination intention, flu vaccination uptake, and human papillomavirus (HPV) vaccination uptake, and completed assessments of vaccine hesitancy, medical mistrust, and racial discrimination. Hierarchical logistic regression modeling examined potential associations between psychosocial predictors and each vaccine type.

RESULTS

Results showed variation in significant predictors across the vaccines of focus. Racial discrimination (OR = 0.64) and medical mistrust (OR = 0.93) were negatively associated with COVID-19 vaccination intention. Vaccine confidence was positively associated with COVID-19 vaccination intention (OR = 2.17) and HPV vaccination uptake (OR = 1.77). Total household income was the only predictor associated with flu vaccination uptake (OR = 1.12).

CONCLUSIONS

These findings suggest that social interventions targeting racial discrimination in healthcare may significantly help address vaccination disparities in rural Black communities. Moreover, results emphasize unique aspects of vaccination behavior in the Black community within Appalachia that may generalize to other Black communities living in rural regions.

Barriers to Service Use Among Dementia Family Caregivers in Rural Appalachia: Implications for Reducing Caregiver Overload

Although the benefits of home- and community-based services (HCBS) to support the needs of older adults are well-established, researchers have persistently reported service underutilization by dementia caregivers to assist them with their caregiving responsibilities. Using the Health Behavior Model and Conservation of Resources Theory, the aim of the current study was to understand what barriers prevent caregivers from using HCBS and the toll it takes on them. Utilizing a sample of 122 rural family caregivers (74% female, 87% white, Mage = 64.86 years) of persons living with dementia (PLwD), simultaneous ordinary least square regressions were employed to understand the association between barriers to service use and the current use of support services and personal services, and concurrently on caregiver role overload. Financial barriers, caregiver's reluctance to use services, and their capability of seeking services were associated with lower use of support services. After controlling for need and enabling factors, caregivers who used more support services, and those who reported system complexities to using support services experienced higher role overload. Financial barriers, system complexities, and caregivers' reluctance also affected the use of personal care services. Despite the use of personal services, caregivers of PLwD with greater needs and fewer enabling factors experienced higher role overload. Study findings suggest that reducing system complexities of HCBS and improving prevention and intervention efforts to facilitate caregivers' awareness of HCBS are needed to address lack of service use and reduce caregiver overload.

Medical Mistrust Among Food Insecure Individuals in Appalachia

This study focused on the relationship between food insecurity and medical mistrust within Appalachia. Food insecurity has negative consequences on health, while medical mistrust can lead to a decrease in health care use, creating additive consequences to already vulnerable populations. Medical mistrust has been defined in various ways, with measures addressing health care organizations and individual health care providers. To determine whether food insecurity has an additive impact on medical mistrust, a cross-sectional survey was completed by 248 residents in Appalachia Ohio while attending community or mobile clinics, food banks, or the county health department. More than one-quarter of the respondents had high levels of mistrust toward health care organizations. Those with high food insecurity levels were more likely to have higher levels of medical mistrust than those with lower levels of food insecurity. Individuals with higher self-identified health issues and older participants had higher medical mistrust scores. Screening for food insecurity in primary care can reduce the impact of mistrust on patient adherence and health care access by increasing patient-centered communication. These findings present a unique perspective on how to identify and mitigate medical mistrust within Appalachia and call attention to the need for further research on the root causes among food insecure residents.

Incremental cost analysis of pediatric hospice care in rural and urban Appalachia

PURPOSE

Considering growing disparities in health outcomes between rural and urban areas of Appalachia, this study compared the incremental Medicaid costs of pediatric concurrent care (implemented by the Patient Protection and Affordable Care Act) versus standard hospice care.

METHODS

Data on 1,788 pediatric hospice patients, from the Appalachian region, collected between 2011 and 2013, were obtained from the Centers for Medicare and Medicaid Services. Incremental per-patient-per-month (PPM) costs of enrollment in concurrent versus standard hospice care were analyzed using multilevel generalized linear models. Increments for analysis were hospice length of stay (LOS).

RESULTS

For rural children enrolled in concurrent hospice care, the mean Medicaid cost of hospice care was $3,954 PPPM (95% CI: $3,223-$4,684) versus $1,933 PPPM (95% CI: $1,357-$2,509) for urban. For rural children enrolled in standard hospice care, the mean Medicaid cost was $2,889 PPPM (95% CI: $2,639-$3,139) versus $1,122 PPPM (95% CI: $980-$1,264) for urban. There were no statistically significant differences in Medicaid costs for LOS of 1 day. However, for LOS between 2 and 14 days, concurrent enrollment decreased total costs for urban children (IC = $-236.9 PPPM, 95% CI: $-421-$-53). For LOS of 15 days or more, concurrent care had higher costs compared to standard care, for both rural (IC = $1,399 PPPM, 95% CI: $92-$2,706) and urban children (IC = $1,867 PPPM, 95% CI: $1,172-$2,363).

CONCLUSIONS

The findings revealed that Medicaid costs for concurrent hospice care were highest among children in rural Appalachia. Future research on factors of high costs of rural care is needed.

Reproductive Autonomy in Appalachia: An Investigation into Perceived Contraceptive Pressure

The reproductive autonomy of persons who can give birth can be impeded through forms of interpersonal violence and coercion. Moreover, macro-level factors (e.g., poverty, discrimination, community violence, legislative policies) may impede the reproductive autonomy of entire communities. This study investigates a form of violence we term perceived contraceptive pressure in Appalachia, an understudied region of the Eastern U.S., regarding reproductive health and decision-making. Through targeted Meta advertising, participants (N = 632) residing in Appalachian zip codes completed an online survey on reproductive health. The focus of this study was to investigate the prevalence of perceived contraceptive pressure, who was at increased risk of experiencing pressure, and the source(s) of perceived pressure. Binomial regressions were conducted on three different dependent variables: perceived pressure to be sterilized, perceived pressure to use birth control, and perceived pressure not to use birth control. Approximately half of all respondents (49.5%) reported experiencing at least one type of pressure targeting contraceptive decision-making. The most prevalent source of perceived pressure to use birth control was from the healthcare provider (67.4%), and the most prevalent source of perceived pressure not to use birth control was the respondent's partner (51.1%). Recommendations for providers serving clients in the Appalachian region include pursuing education regarding contraceptive pressure at the individual level and macro-level. In addition, Appalachian residents may benefit from educational programming on reproductive autonomy, healthy relationships, and how to navigate pressure in relationships.

Influence of Spiritual Engagement on Appalachian Older Adults' Health: A Systematic Review

Appalachia leads the country in mortality related to chronic comorbidities, such as heart disease, cancer, depression, and suicide. Appalachian older adults experience disproportionate risks for poor health outcomes. Spirituality is integral to Appalachian culture, and many older adults use spiritual engagement (SE) to cope with health challenges. Despite these connections, there is limited evidence about SE and well-being in this population. Therefore, the current systematic review addresses the literature gap of how SE influences health of Appalachian older adults. Using thematic synthesis, we analyzed 11 qualitative and three mixed methods studies. Major findings indicate that SE positively impacts holistic health through adaptive coping, guided partnerships with God, decreased loneliness, and enhanced sense of purpose. Future studies could examine SE practices among diverse populations, SE virtual experiences, and SE nursing assessments. Understanding how SE influences health of Appalachian older adults could prepare nurses to reduce disparities and improve health outcomes for this vulnerable population.

Outcomes of a Caregiver-Focused Short Message Service (SMS) Intervention to Reduce Intake of Sugar-Sweetened Beverages in Rural Caregivers and Adolescents

This study examined enrollment, retention, engagement, and behavior changes from a caregiver short message service (SMS) component of a larger school-based sugar-sweetened beverage (SSB) reduction intervention. Over 22 weeks, caregivers of seventh graders in 10 Appalachian middle schools received a two-way SMS Baseline Assessment and four monthly follow-up assessments to report their and their child's SSB intake and select a personalized strategy topic. Between assessments, caregivers received two weekly one-way messages: one information or infographic message and one strategy message. Of 1873 caregivers, 542 (29%) enrolled by completing the SMS Baseline Assessment. Three-quarters completed Assessments 2-5, with 84% retained at Assessment 5. Reminders, used to encourage adherence, improved completion by 19-40%, with 18-33% completing after the first two reminders. Most caregivers (72-93%) selected a personalized strategy and an average of 28% viewed infographic messages. Between Baseline and Assessment 5, daily SSB intake frequency significantly (p < 0.01) declined for caregivers (-0.32 (0.03), effect size (ES) = 0.51) and children (-0.26 (0.01), ES = 0.53). Effect sizes increased when limited to participants who consumed SSB twice or more per week (caregivers ES = 0.65, children ES = 0.67). Findings indicate that an SMS-delivered intervention is promising for engaging rural caregivers of middle school students and improving SSB behaviors.

Four decades of regional wet deposition, local bulk deposition, and stream-water chemistry show the influence of nearby land use on forested streams in Central Appalachia

Hydrologic monitoring began on two headwater streams (<1 km²) on the University of Kentucky's Robinson Forest in 1971. We evaluated stream-water (1974-2013) and bulk-deposition (wet + dust) (1984-2013) chemistry in the context of regional wet-deposition patterns that showed decreases in both sulfate and nitrate concentrations as well as proximal surface-mine expansion. Decadal time steps (1974-83, 1984-93, 1994-2003, 2004-2013) were used to quantify change. Comparison of the first two decades showed similarly decreased sulfate (minimum flow-adjusted annual-mean concentration of ≈13.5 mg/L in 1982 to 8.8 mg/L in 1992) and increased pH (6.6-6.8) in both streams, reflecting contemporaneous changes in both bulk and wet deposition. In contrast, concentrations of nitrate (0.14 to >0.25 mg/L) and base cations increased between these two decades, coinciding with expansion of surface mining between 1985 and 1995. In 2004, stream-water pH (6.7 in 2004), sulfate (9.2 mg/L), and nitrate (>0.11 mg/L) were similar to 1982, despite wet-deposition concentrations being lower. Base-cation concentrations were higher in the stream adjacent to ongoing surface mining relative to the stream situated near the middle of the experimental forest. However, pH decreased to approximately 5.7 by 2013 for both streams, which, combined with a shift in dominant cations from calcium to magnesium and potassium, indicates that the soil-buffering capacity of this landscape has been exceeded. Ratios of bulk deposition and stream-water concentrations indicate enrichment of sulfate (1.7-25.2) and cations (0.5-64.8), but not nitrogen (0.1-5.6), indicating that the Forest is not nitrogen saturated and that ongoing changes in water-quality are sulfate driven. When concentrations were adjusted to account for changes in streamflow (climate) over the 4 decades, external influences (land management/regulation) explained most change. The amount and direction of change differed among constituents, both between consecutive decades and between the first and last decades, reflecting the influence of localized surface mining even as regional wet deposition continued to improve due to the Clean Air Act. The implication is that localized stressors have the potential to out-pace the benefits of national environmental policies for communities that depend on local water-resources in similar environments.

Impact of the Appalachian Career Training in Oncology (ACTION) Program on Undergraduate Participants

Kentucky ranks first in the nation in cancer incidence and mortality. The Appalachian region of the state experiences the highest cancer disparities due to inequities in many social determinants of health. As a strategy for addressing cancer and education disparities in the region, the Appalachian Career Training in Oncology (ACTION) Program at the University of Kentucky Markey Cancer Center engaged 16 Appalachian-native undergraduate student participants annually in cancer-related activities. Students were recruited on an annual basis for the 2-year ACTION program. Entry, mid-point, and exit surveys were administered to participants. Classical test theory and exploratory factor analysis were used to examine the instruments used for program evaluation, whereas repeated measures ANOVA, paired t-tests, chi-squared, and post hoc analyses were used to analyze 6 years of survey data. There was a significant increase in participants' understanding of cancer-related topics among the entry, midpoint, and exit surveys (p < .001) and a significant increase in comfort with research, clinical, and outreach activities between entry and midpoint and entry and exit (p < .001), but not between midpoint and exit. With respect to research skills and perceptions of the program, increases in mean scores were observed between midpoint and exit, but these increases were not statistically significant (p = .167, p = 223, respectively). ACTION increased participants' understanding of cancer-related topics; comfort with research, clinical, and outreach activities; and research skills. These data suggest that ACTION has a significant impact on participants.

Biofluorescent sexual dimorphism revealed in a southern Appalachian endemic salamander, Plethodon metcalfi

Biofluorescence occurs when a living organism absorbs high energy light and reemits it at longer wavelengths. Many species within clades of vertebrates are known to fluoresce including mammals, reptiles, birds, and fish. Most, if not all, amphibians exhibit biofluorescence when exposed to either blue (440-460 nm) or ultra-violet (360-380 nm) wavelengths of light. Salamanders (Lissamphibia: Caudata) appear to consistently fluoresce in green wavelengths (520-560 nm) when excited by blue light. Biofluorescence is theorized to have many ecological functions including mate signaling, camouflage, and mimicry. Despite the discovery of their biofluorescence, its role in salamander ecology and behavior remains unresolved. In this study we present the first case of biofluorescent sexual dimorphism within Amphibia and the first documentation of the biofluorescent pattern of a salamander within the Plethodon jordani species complex. This sexually dimorphic trait was discovered in the southern Appalachian endemic species, Southern Gray-Cheeked Salamander (Plethodon metcalfi, Brimley in Proc Biol Soc Wash 25:135-140, 1912), and may extend into other species within the Plethodon jordani and Plethodon glutinosus species complexes. We propose that this sexually dimorphic trait could be related to fluorescence of ventral modified granular glands used in plethodontid chemosensory communication.

Land cover and community water system characteristics as predictors of Safe Drinking Water Act violations in Central Appalachia, USA

Upstream anthropogenic land cover can degrade source drinking water quality and thereby inhibit the ability of a community water system to provide safe drinking water. This study aimed to predict differences in Safe Drinking Water Act (SDWA) compliance between water systems based on upstream land cover in Central Appalachia and to examine whether national trends correlating violations with system size and source type were relevant for this region. Multiple generalized linear mixed models assessed relationships between SDWA violations and the distance weighted land cover proportions associated with the water system's contributing source watershed, as well as county economic status, system size, and water source. Results indicate that rates of monitoring and reporting violations were significantly higher for smaller water systems in more economically distressed counties. Interestingly, increases in surface mining landuse and high density development decreased monitoring and reporting violations, which may reflect impacts of associated economic development. Increases in low intensity development increased the likelihood of health-based violations. To protect public health, community managers should consider source water protection and/or upgrading drinking water system treatment capacity prior to developing previously undeveloped areas and further motivate compliance with monitoring and reporting requirements.

Examining Psychological and Knowledge Barriers to Colorectal Cancer Screening in Rural Appalachian Kentucky

While recent rates of colorectal cancer (CRC) screening have improved in Appalachian Kentucky due to public health efforts, they remain lower compared to both KY as a whole, and the USA. Suboptimal screening rates represent a missed opportunity to engage in early detection and prevention. The purpose of this study is to determine the impact that lack of knowledge has on psychological barriers (e.g., fear and embarrassment) to CRC screening as well as the potential effect of a psychosocial intervention to reduce these barriers. Participants were recruited through faith-based organizations and other community sites. After randomizing participants to either an early or delayed group, a faith-based group education and motivational interviewing intervention was administered. Existing and pilot tested instruments were used to assess knowledge and potential psychological barriers. Data were analyzed using paired t tests and linear regression. We hypothesized that (1) psychological barriers are associated with inadequate knowledge and (2) the intervention, by improving knowledge, could reduce these barriers and increase screening rates. There was a small but significant reduction in psychological barriers (-0.11, p value = 0.015) and moderate increases in CRC knowledge scores (+0.17, p value = 0.06). There was no evidence that the intervention affected these measures (+0.10, p value = 0.58). The relationship between lower barrier scores and increased knowledge was significant at follow up (-0.05, 95% CI (-0.09, -0.00)). An increase in CRC knowledge was correlated with a small but significant decrease in psychological barriers, although there was no evidence that these changes were associated with one another. Future cognitive-based interventions may be effective in increasing CRC knowledge and reducing barriers, but new intervention approaches should be considered.

Factors associated with perceived ease of access to syringes in Appalachian North Carolina

PURPOSE

To examine associations between perceived ease of syringe access, syringe sources, injection behaviors, and law enforcement (LE) interactions among people who inject drugs (PWID) in rural Appalachian North Carolina (NC).

METHODS

Using respondent-driven sampling, a diverse sample of 309 self-reported PWID were recruited from rural Appalachian NC. Data were collected via audio computer-assisted self-interview technology from February 2019 through March 2020. Respondents reported demographics, sources of syringes, LE interactions, and injection behaviors. Univariate, bivariate, and linear regression analyses were performed.

FINDINGS

Respondents most often obtained syringes from pharmacies and syringe service programs (SSPs). Twenty-one percent disagreed that it was easy to obtain sterile syringes, with 28% reporting low or no access to an SSP. PWID who reported longer physical distances to an SSP had greater difficulty accessing syringes (P<.001). PWID who reported greater ease of access to syringes reported engaging in receptive syringe sharing less often (P<.01). PWID who were stopped and searched by LE more often reported injecting drugs somebody else prepared with nonsterile supplies more often (P<.01). Participants shared used injection supplies more than twice as often than they shared used syringes.

CONCLUSIONS

These results underscore the importance of SSPs to mitigate the spread of human immunodeficiency virus and viral hepatitis in rural areas. Supporting mobile SSP services in rural areas could increase access to sterile syringes and injection supplies. SSPs should educate PWID about the importance of not sharing injection supplies. Pharmacies could increase syringe access in areas where SSPs do not operate.

Implementing the Better Starts For All Pilot Mobile and Telehealth Intervention in Ohio Appalachia: Improving Access to Maternal Healthcare

INTRODUCTION

Women in Ohio Appalachia experience greater maternal health disparities relative to the general U.S. population, resulting in poorer health outcomes. This paper describes the Ohio Better Starts for All (BSFA) program that provides mobile maternal health services in rural Ohio.

METHODS

This three-year intervention was delivered through a community-clinical partnership in Ohio Appalachia. The program's preliminary evaluation and opportunities were informed by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

RESULTS

Over six months, 86 patients were referred to the BSFA program, 54 (62.8 %) were seen by the maternal care team, and 14 out of 19 scheduled clinic days were held. Five clinics were canceled due to inclement weather, mobile unit breakdown, or provider COVID-19 infection.

DISCUSSION

Maternal care providers must provide equitable care to patients, with particular attention to those who face substantial challenges accessing obstetric services. The BSFA program offers one promising solution to help women overcome barriers to accessing care.

"That Was the Happiest Time of My Life": Understanding Childhood Eco-Connections in Appalachian Communities

The goal of this study was to explore facets of childhood eco-connections, using retrospective qualitative data from adults. One hundred and forty-five adults from predominantly rural and small-town communities in southern Appalachia (71.7% female), average age 36.23 years (SD = 12.08) participated in semi-structured qualitative interviews on key life experiences and the places they grew up. Mentions about place-related childhood memories or interactions were grouped into four themes based on exploratory thematic content analysis: nature nostalgia (positive reminiscences about nature experiences); nature immersion (extensive contact with the natural world during childhood); formative experiences with nature (nature interactions that taught a skill or life lesson); and rhythms of nature (appreciation of seasonal or cyclical patterns). Childhood eco-connections are multifaceted and often emerge from early impactful or intense experiences. Pro-environmentalism messages to youth may benefit from more references to childhood eco-connections.
