RESUMO
BACKGROUND AND OBJECTIVES: Poverty is associated with greater stroke incidence. The relationship between poverty and stroke recurrence is less clear. METHODS: In this population-based study, incident strokes within the Greater Cincinnati/Northern Kentucky region were ascertained during the 2015 study period and followed up for recurrence until December 31, 2018. The primary exposure was neighborhood socioeconomic status (nSES), defined by the percentage of households below the federal poverty line in each census tract in 4 categories (≤5%, >5%-10%, >10%-25%, >25%). Poisson regression models provided recurrence rate estimates per 100,000 residents using population data from the 2015 5-year American Community Survey, adjusting for age, sex, and race. In a secondary analysis, Cox models allowed for the inclusion of vascular risk factors in the assessment of recurrence risk by nSES among those with incident stroke. RESULTS: Of 2,125 patients with incident stroke, 245 had a recurrent stroke during the study period. Poorer nSES was associated with increased stroke recurrence, with rates of 12.5, 17.5, 25.4, and 29.9 per 100,000 in census tracts with ≤5%, >5%-10%, >10%-25%, and >25% below the poverty line, respectively (p < 0.01). The relative risk (95% CI) for recurrent stroke among Black vs White individuals was 2.54 (1.91-3.37) before adjusting for nSES, and 2.00 (1.47-2.74) after adjusting for nSES, a 35.1% decrease. In the secondary analysis, poorer nSES (HR 1.74, 95% CI 1.10-2.76 for lowest vs highest category) and Black race (HR 1.31, 95% CI 1.01-1.70) were both independently associated with recurrence risk, though neither retained significance after full adjustment. Age, diabetes, and left ventricular hypertrophy were associated with increased recurrence risk in fully adjusted models. DISCUSSION: Residents of poorer neighborhoods had a dose-dependent increase in stroke recurrence risk, and neighborhood poverty accounted for approximately one-third of the excess risk among Black individuals. These results highlight the importance of poverty, race, and the intersection of the 2 as potent drivers of stroke recurrence.

BACKGROUND: Hypertension is a stroke risk factor with known disparities in prevalence and management between Black and White patients. We sought to identify if racial differences in presenting blood pressure (BP) during acute ischemic stroke exist. METHODS AND RESULTS: Adults with acute ischemic stroke presenting to an emergency department within 24 hours of last known normal during study epochs 2005, 2010, and 2015 within the Greater Cincinnati/Northern Kentucky Stroke Study were included. Demographics, histories, arrival BP, National Institutes of Health Stroke Scale score, and time from last known normal were collected. Multivariable linear regression was used to determine differences in mean BP between Black and White patients, adjusting for age, sex, National Institutes of Health Stroke Scale score, history of hypertension, hyperlipidemia, smoking, stroke, body mass index, and study epoch. Of 4048 patients, 853 Black and 3195 White patients were included. In adjusted analysis, Black patients had higher presenting systolic BP (161 mm Hg [95% CI, 159-164] versus 158 mm Hg [95% CI, 157-159], P<0.01), diastolic BP (86 mm Hg [95% CI, 85-88] versus 83 mm Hg [95% CI, 82-84], P<0.01), and mean arterial pressure (111 mm Hg [95% CI, 110-113] versus 108 mm Hg [95% CI, 107-109], P<0.01) compared with White patients. In adjusted subanalysis of patients <4.5 hours from last known normal, diastolic BP (88 mm Hg [95% CI, 86-90] versus 83 mm Hg [95% CI, 82-84], P<0.01) and mean arterial pressure (112 mm Hg [95% CI, 110-114] versus 108 mm Hg [95% CI, 107-109], P<0.01) were also higher in Black patients. CONCLUSIONS: This population-based study suggests differences in presenting BP between Black and White patients during acute ischemic stroke. Further study is needed to determine whether these differences influence clinical decision-making, outcome, or clinical trial eligibility.

Wild turkeys (Meleagris gallopavo) are an important game species throughout the geographic range. Populations throughout multiple regions of the US have been declining, including in Kentucky, US, raising concerns among managers and resource users. To better understand the overall population health, we performed postmortem examinations and targeted pathogen, mineral, and toxicant testing on 36 adult male, apparently healthy, wild turkeys that were hunter harvested in western Kentucky during April 2018. We found that birds were in fair to good nutritional condition with no significant gross or microscopic lesions. Ticks (Amblyomma spp.) and lice (three species) were present on 94 and 31% of birds, respectively. We commonly detected intestinal nematodes and cestodes and found coccidian oocysts in 39% and capillarid eggs in 6% of birds. The prevalences of lymphoproliferative disease virus and reticuloendotheliosis virus were 39 and 11%, respectively. Spleen samples tested with PCR were positive for Borrelia burgdorferi, Haemoproteus sp., and Leucocytozoon sp. in 11, 83, and 3%, respectively. Based on a subjective histologic assessment of testis tissues, most birds had widespread and abundant sperm present. Mineral analysis and broad toxicant screening on liver samples from 32 turkeys were unremarkable. Further work is needed to assess potential population risk factors and to determine individual- and population-level impacts of pathogens on adults and poults.

BACKGROUND: Hospitalizations are more resource intensive and expensive than outpatient care. Therefore, type 2 diabetes-related preventable hospitalization are a major topic of research efficiency in the healthcare system. OBJECTIVES: Analyze county level variation in type 2 diabetes-related preventable hospitalization rates in Kentucky before the Medicaid expansion (2010-2013) and after the Medicaid expansion (2014-2017). DESIGN: Geographic mapping and cluster analysis. SETTING: Data for a state of the United States of America. METHODS: We used the KID data to generate geographic mapping for type 2 diabetes-related preventable hospitalizations to visualize rates. We included all Kentucky discharges of age 18 years and older with the ICD9/10 principal diagnosis code for type 2 diabetes. Then, we conducted cluster analysis techniques to compare county-level variation in type 2 diabetes-related preventable hospitalization rates across Kentucky counties pre- and post-Medicaid expansion. MAIN OUTCOME AND MEASURES: County type 2 diabetes-related preventable hospitalization pre- and post-Medicaid expansion. RESULTS: From 2010-2017, type 2 diabetes-related preventable hospitalization discharge rates reduced significantly in the period of the post-Medicaid expansion (P=.001). The spatial statistics analysis revealed a significant spatial clustering of counties with similar rates of type 2 diabetes-related preventable hospitalization in the south, east, and southeastern Kentucky pre- and post-Medicaid expansion (positive z-score and positive Moran's Index value (P>.05). Also, there was a significant clustering of counties with low type 2 diabetes-related preventable hospitalization rates in the north, west, and central regions of the state pre-Medicaid expansion and post-Medicaid expansion (positive z-score and positive Moran's Index value (P>.05). CONCLUSION: Kentucky counties in the southeast have experienced a significant clustering of highly avoidable hospitalization rates during both periods. Focusing on the vulnerable counties and the economic inequality in Kentucky could lead to efforts to lowering future type 2 diabetes-related preventable hospitalization rates. LIMITATIONS: We used de-identified data which does not provide insights into the frequency of hospitalizations per patient. An individual patient may be hospitalized several times and counted as several individuals.

BACKGROUND: Medicaid expansion improved insurance coverage for patients with chronic conditions and low income. The effect of Medicaid expansion on patients with IBD from high-poverty communities is unknown. OBJECTIVE: This study aimed to evaluate the impact of Medicaid expansion in Kentucky on care for patients with IBD from the Eastern Kentucky Appalachian community, a historically impoverished area. DESIGN: This study was a retrospective, descriptive, and ecological study. SETTINGS: This study was conducted in Kentucky using the Hospital Inpatient Discharge and Outpatient Services Database. PATIENTS: All encounters for IBD care for 2009-2020 for patients from the Eastern Kentucky Appalachian region were included. MAIN OUTCOME MEASURES: The primary outcomes measured were proportions of inpatient and emergency encounters, total hospital charge, and hospital length of stay. RESULTS: Eight hundred twenty-five preexpansion and 5726 postexpansion encounters were identified. Postexpansion demonstrated decreases in the uninsured (9.2%-1.0%; p < 0.001), inpatient encounters (42.7%-8.1%; p < 0.001), emergency admissions (36.7%-12.3%; p < 0.001), admissions from the emergency department (8.0%-0.2%; p < 0.001), median total hospital charge ($7080-$3260; p < 0.001), and median total hospital length of stay (4-3 days; p < 0.001). Similarly, postexpansion demonstrated increases in Medicaid coverage (18.8%-27.7%; p < 0.001), outpatient encounters (57.3%-91.9%; p < 0.001), elective admissions (46.9%-76.2%; p < 0.001), admissions from the clinic (78.4%-90.2%; p < 0.001), and discharges to home (43.8%-88.2%; p < 0.001). LIMITATIONS: This study is subject to the limitations inherent in being retrospective and using a partially de-identified database. CONCLUSION: This study is the first to demonstrate the changes in trends in care after Medicaid expansion for patients with IBD in the Commonwealth of Kentucky, especially Appalachian Kentucky, showing significantly increased outpatient care utilization, reduced emergency department encounters, and decreased length of stays. IMPACTO DE LA LEY DEL CUIDADO DE SALUD A BAJO PRECIO EN LA PROVISIN DE ACCESO EQUITATIVO A LA ATENCIN MDICA PARA LA ENFERMEDAD INFLAMATORIA INTESTINAL EN LA REGIN DE LOS APALACHES DE KENTUCKY: ANTECEDENTES: La expansión de Medicaid mejoró la cobertura de seguro para pacientes con enfermedades crónicas y bajos ingresos. Se desconoce el efecto de la expansión de Medicaid en pacientes con enfermedad inflamatoria intestinal de comunidades de alta pobreza.OBJETIVO: Este estudio tuvo como objetivo evaluar el impacto de la expansión de Medicaid en Kentucky en la atención de pacientes con enfermedad inflamatoria intestinal de la comunidad de los Apalaches del este de Kentucky, un área históricamente empobrecida.DISEÑO: Este estudio fue un estudio retrospectivo, descriptivo, ecológico.ESCENARIO: Este estudio se realizó en Kentucky utilizando la base de datos de servicios ambulatorios y de alta hospitalaria en pacientes hospitalizados.PACIENTES: Se incluyeron todos los encuentros para la atención de la enfermedad inflamatoria intestinal de 2009-2020 para pacientes de la región de los Apalaches del este de Kentucky.MEDIDAS DE RESULTADO PRINCIPALES: Los resultados primarios medidos fueron proporciones de encuentros de pacientes hospitalizados y de emergencia, cargo hospitalario total y duración de la estancia hospitalaria.RESULTADOS: Se identificaron 825 encuentros previos a la expansión y 5726 posteriores a la expansión. La posexpansión demostró disminuciones en los no asegurados (9.2% a 1.0%, p < 0.001), encuentros de pacientes hospitalizados (42.7% a 8.1%, p < 0.001), admisiones de emergencia (36.7% a 12.3%, p < 0,001), admisiones desde el servicio de urgencias (8.0% a 0.2%, p < 0.001), la mediana de los gastos hospitalarios totales ($7080 a $3260, p < 0.001) y la mediana de la estancia hospitalaria total (4 a 3 días, p < 0.001). De manera similar, la cobertura de Medicaid (18.8% a 27.7%, p < 0.001), consultas ambulatorias (57.3% a 91.9%, p < 0.001), admisiones electivas (46.9% a 76.2%, p < 0.001), admisiones desde la clínica (78.4% al 90.2%, p < 0.001), y las altas domiciliarias (43.8% al 88.2%, p < 0.001) aumentaron después de la expansión.LIMITACIONES: Este estudio está sujeto a las limitaciones inherentes de ser retrospectivo y utilizar una base de datos parcialmente desidentificada.CONCLUSIONES: Este estudio es el primero en demostrar los cambios en las tendencias en la atención después de la expansión de Medicaid para pacientes con enfermedad inflamatoria intestinal en el Estado de Kentucky, especialmente en los Apalaches de Kentucky, mostrando un aumento significativo en la utilización de la atención ambulatoria, visitas reducidas al departamento de emergencias y menor duración de la estancia hospitalaria.

BACKGROUND: Medicaid expansion impacted patients when assessed at a national level. However, of the 32 states that expanded Medicaid, only three were Southern states. Whether results apply to Southern states that share similar geopolitical perspectives remains elusive. We aimed to assess the impact of Medicaid expansion on breast cancer diagnosis and treatment in 8 Southern states in the US. STUDY DESIGN: We identified uninsured or Medicaid patients (age 40 to 64 years) diagnosed with invasive breast cancer from 2011 to 2018 in Southern states from the North American Association of Central Cancer Registries-Cancer in North America Research Dataset. Medicaid-expanded states ([MES], Louisiana, Kentucky, Arkansas) were compared with non-MES ([NMES], Tennessee, Alabama, Mississippi, Texas, Oklahoma) using multivariate logistic regression and differences-in-differences analyses during pre- and postexpansion periods; p < 0.05 was considered statistically significant. RESULTS: Among 21,974 patients, patients in MES had increased odds of Medicaid insurance by 43% (odds ratio 1.43, p < 0.01) and decreased odds of distant-stage disease by 7% (odds ratio 0.93, p = 0.03). After Medicaid expansion, Medicaid patients increased by 10.6% in MES (Arkansas, Kentucky), in contrast to a 1.3% decrease in NMES (differences-in-differences 11.9%, p < 0. 0001, adjusting for age, race/ethnicity, rural-urban status, and poverty status). MES (Arkansas, Kentucky) had 2.3% fewer patients diagnosed with distant-stage disease compared with a 0.5% increase in NMES (differences-in-differences 2.8%, p = 0.01, after adjustment). Patients diagnosed in MES had higher odds of receiving treatment (odds ratio 2.27, p = 0.03). CONCLUSIONS: Unlike NMES, MES experienced increased Medicaid insured, increased treatment, and decreased distant-stage disease at diagnosis. Medicaid expansion in the South leads to earlier and more comprehensive treatment of breast cancer.

BACKGROUND: In response to the opioid epidemic, many states implemented mandates requiring providers to check prescription drug monitoring programs (PDMPs) before prescribing opioids. We examine how overlapping benzodiazepine and opioid prescriptions changed after Kentucky implemented a PDMP mandate in July 2012. METHODS: We conducted an interrupted time series analysis using monthly data from Kentucky's PDMP from 2010 to 2016. Separate analyses were conducted for overlapping prescriptions from a single provider or multiple providers, and by sex and age group. We also conducted an individual-level longitudinal analysis that compared changes in utilization patterns after the mandate went into effect to changes in earlier periods during which the mandate was not in effect. RESULTS: Kentucky's PDMP mandate was associated with an immediate 7.5 % decline in the rate of overlapping benzodiazepine and opioid prescriptions and a significant change in the trend from increasing to decreasing. Approximately half of the immediate effect in level terms was explained by decreases in overlapping prescriptions written by a single provider. Our longitudinal analysis suggests that over one year the mandate reduced initiation of overlapping prescriptions by 29.3 % and reduced continuation of overlapping prescriptions by 9.4 %. The effects of the policy were largest for women and men aged 36-50. CONCLUSIONS: Though not the main rationale for the policy, Kentucky's PDMP mandate reduced overlapping prescriptions of benzodiazepines and opioids. Further efforts to reduce overlapping prescriptions should consider the effects on populations such as women over 50, who have high rates of overlapping prescriptions.

Young Black men who have sex with men (MSM) living with HIV evidence the lowest rates of linkage to care and viral suppression of all US MSM. Kentucky, identified by the US Department of Health and Human Services as a "hot spot" state with elevated HIV incidence compared to the rest of the country, exhibits similar racialized outcomes. Structural, interpersonal, and individual drivers of engagement along the HIV care continuum among people living with HIV have been identified, primarily through quantitative designs. However, the mechanisms by which these factors shape HIV care engagement, and the ways they may combine or reinforce each other, as well as from the lived experience of young Black MSM living with HIV, have been studied to a lesser extent. In this study, a purposive sample of n = 29 HIV-positive young Black MSM (age M = 25 years old; 38% retained in care) residing in Kentucky participated in in-depth interviews. Factors that were most influential on engagement varied along the continuum, with health insurance status and knowledge of HIV being relatively more influential to diagnosis, and housing stability, psychological processes, and interpersonal relationships being more influential on retention. For some participants, barriers to care at multiple levels had a mutually influencing and intensifying impact on care engagement. Additional efforts to center the voices of young Black MSM living with HIV will help illuminate acceptable and sustainable interventions for increasing their care engagement and narrowing persistent racial disparities in HIV morbidity and mortality.

BACKGROUND: Little is known about the distribution of antibiotic use in individual children over time. The amoxicillin index is a recently proposed metric to assess first-line antibiotic prescribing to children. METHODS: We constructed a cohort of continuously enrolled Medicaid children using enrollment claims from 2012 to 2017. Pharmacy claims were used to identify antibiotic prescription data. RESULTS: Among 169 724 children with 6 years of Medicaid enrollment, 10 804 (6.4%) had no antibiotic prescription claims during the study period; 43 473 (25.6%) had 1-3 antibiotics; 34 318 (20.2%) had 4-6 antibiotics; 30 994 (18.3%) had 7-10; 35 018 (20.6%) had 11-20; and 15 117 (8.9%) children had more than 20 antibiotic prescriptions. Overall, the population had a median total of 6 antibiotic prescriptions during the study period, but use was higher in certain patient groups: younger age (8 antibiotic fills over the 6-year period, [IQR 4-14]), White children (7 [IQR 3-13], compared to 3 [IQR 1-6] in Black children), rural settings (9 [IQR 4-15]) and chronic conditions (8 [IQR 4-15]). Higher-use groups also had lower rates of amoxicillin fills, reported as amoxicillin indices. CONCLUSIONS: Antibiotic use is common among most children insured by Kentucky Medicaid. A number of fills over time were higher in younger children, and in White children, children living in rural settings and children with chronic conditions. Patients with higher recurrent antibiotic use are important targets for designing high-impact antibiotic stewardship efforts.

BACKGROUND: The lack of research on cost-related health literacy among colorectal cancer (CRC) survivors warrants further evaluation. OBJECTIVES: The objective of this study was to examine prevalence of low literacy (health, cancer, and insurance literacy), and numeracy and their association with sociodemographic factors in a group of Kentucky CRC survivors. METHODS: Based on data from the Kentucky Cancer Registry, this cross-sectional study evaluated survey results from January 2019 to November 2019 for the prevalence of low cost-related health literacy. FINDINGS: Overall, 104 participants had adequate health literacy (77%) and cancer health literacy (71%). However, fewer CRC survivors had high numeracy (16%) and confidence in choosing and using health insurance (18%). Thirty-one percent reported competence in their ability to select a health insurance plan and use it to access timely and appropriate healthcare services. Those with lower levels of education or those enrolled in a public health insurance plan were more likely to have lower health literacy, insurance literacy, and numeracy.

Maternal address information captured on birth records is increasingly used to estimate residential environmental exposures during pregnancy. However, there has been limited assessment of the geocoding precision of birth records, particularly since the adoption of the 2003 standard birth certificate in 2015. To address this gap, this study evaluated the geocoding precision of live and stillbirth records of Kentucky residents over ten years, from 2008 through 2017. This study summarized the demographic characteristics of imprecisely geocoded records and, using a bivariate logistic regression, identified covariates associated with poor geocoding precision among three population density designations-metro, non-metro, and rural. We found that in metro areas, after adjusting for area deprivation, education, and the race, age and education of both parents, records for Black mothers had 48% lower odds of imprecise geocoding (aOR=0.52, 95% CI: 0.48, 0.56), while Black women in rural areas had 96% higher odds of imprecise geocoding (aOr=1.96, 95% CI: 1.68, 2.28). This study also found that over the study period, rural and non-metro areas began with a high proportion of imprecisely geocoded records (38% in rural areas, 19% in non-metro), but both experienced an 8% decline in imprecisely geocoded records over the study period (aOr=0.92, 95% CI: 0.92, 0.94). This study shows that, while geocoding precision has improved in Kentucky, further work is needed to improve geocoding in rural areas and address racial and ethnic disparities.

PURPOSE: To evaluate whether Kentucky counties that established a new syringe services program realized a significant decline in the incidence rate of a set of infectious disease diagnoses commonly transmitted via injection drug use. METHODS: Longitudinal count models of within-county rates of newly diagnosed infections among populations at risk were estimated using Medicaid claims/encounters data. Generalized estimating equation models were used to report incident rate ratios of 6 diagnoses: (1) HIV; (2) hepatitis C; (3) hepatitis B; (4) osteomyelitis; (5) endocarditis; and (6) skin/soft tissue infection. To investigate whether a delay in effect was present, separate models were fit to estimate the effects of establishing a syringe services program: at its opening date, and again at 1, 3, and 6 months postopening date. FINDINGS: Taken together, the aggregated within-county incidence rate of these 6 diagnoses was significantly lower following the implementation of a syringe services program (P < .05). Our models estimated that counties which opted to open a syringe services program realized an approximate month-over-month decline in new diagnoses of 0.5% among the population at risk. CONCLUSIONS: These results lend further support to previous conclusions made in the public health literature regarding the efficacy of syringe services programs. Specifically, declines in incidence rates were observable beginning at 1 month post syringe services program opening. These results are particularly notable due to the typical setting in which these syringe services programs operated-rural communities of fewer than 40,000 residents.

INTRODUCTION: The World Health Organization (WHO) declared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a pandemic in March 2020. Theoretically, homeless patients could have disproportionately worse outcomes from COVID-19, but little research has corroborated this claim. This study aimed to examine the demographics and incidence of COVID-19 in homeless vs non-homeless emergency department (ED) patients. METHODS: This is a retrospective study of all patients seen in the University of Louisville Hospital Emergency Department (ULH ED) from March 2019 to December 2020, excluding January and February 2020. Data was collected from the Kentucky Homeless Management Information System (HMIS) and ULH electronic health records. RESULTS: A total of 51,532 unique patients had 87,869 visits during the study period. There was a 18.1% decrease in homeless patient visits over the time period, which was similar to the decrease in non-homeless patient visits (19.2%). In the total population, 9471 individuals had known COVID-19 testing results, with a total of 610 positive (6.4% positivity rate). Of the 712 homeless ED patients, 39 tested positive (5.5% positivity rate). After adjusting for age, gender identity, race, and insurance, there was no statistically significant difference in test positivity between homeless and non-homeless patients, OR 1.23 (0.88, 1.73). Homeless patients were less likely to be admitted to either the intensive care unit (ICU) or hospital (OR = 0.55, 95% CI: OR 0.51, 0.60) as they were more likely to be discharged (OR = 1.65, 95% CI: 1.52, 1.79). CONCLUSION: Previous literature has indicated that higher disease burden, lack of access to social distancing, and poor hygiene would increase the risk of homeless individuals contracting COVID-19 and experiencing serious morbidity. However, this study found that homelessness was not an independent risk factor for COVID-19 infection.

With the introduction of precision medicine, treatment options for non-small-cell lung cancer have improved dramatically; however, underutilization, especially in disadvantaged patients, like those living in rural Appalachian regions, is associated with poorer survival. Molecular tumor boards (MTBs) represent a strategy to increase precision medicine use. UK HealthCare at the University of Kentucky (UK) implemented a statewide MTB in January 2017. We wanted to test the impact of UK MTB review on overall survival in Appalachian and other regions in Kentucky. METHODS: We performed a case-control study of Kentucky patients newly diagnosed with non-small-cell lung cancer between 2017 and 2019. Cases were reviewed by the UK MTB and were compared with controls without UK MTB review. Controls were identified from the Kentucky Cancer Registry and propensity-matched to cases. The primary end point was the association between MTB review and overall patient survival. RESULTS: Overall, 956 patients were included, with 343 (39%) residing in an Appalachian region. Seventy-seven (8.1%) were reviewed by the MTB and classified as cases. Cox regression analysis showed that poorer survival outcome was associated with lack of MTB review (hazard ratio [HR] = 8.61; 95% CI, 3.83 to 19.31; P < .0001) and living in an Appalachian region (hazard ratio = 1.43; 95% CI, 1.17 to 1.75; P = .004). Among individuals with MTB review, survival outcomes were similar regardless of whether they lived in Appalachia or other parts of Kentucky. CONCLUSION: MTB review is an independent positive predictor of overall survival regardless of residence location. MTBs may help overcome some health disparities for disadvantaged populations.

Serological assays intended for diagnosis, sero-epidemiologic assessment, and measurement of protective antibody titers upon infection or vaccination are essential for managing the SARS-CoV-2 pandemic. Serological assays measuring the antibody responses against SARS-CoV-2 antigens are readily available. However, some lack appropriate characteristics to accurately measure SARS-CoV-2 antibodies titers and neutralization. We developed an Enzyme-linked Immunosorbent Assay (ELISA) methods for measuring IgG, IgA, and IgM responses to SARS-CoV-2, Spike (S), receptor binding domain (RBD), and nucleocapsid (N) proteins. Performance characteristics of sensitivity and specificity have been defined. ELISA results show positive correlation with microneutralization and Plaque Reduction Neutralization assays with infectious SARS-CoV-2. Our ELISA was used to screen healthcare workers in Louisville, KY during the first wave of the local pandemic in the months of May and July 2020. We found a seropositive rate of approximately 1.4% and 2.3%, respectively. Our analyses demonstrate a broad immune response among individuals and suggest some non-RBD specific S IgG and IgA antibodies neutralize SARS-CoV-2.

Early in the pandemic, slowing the spread of novel coronavirus disease 2019 (COVID-19) relied on non-pharmaceutical interventions. All U.S. states adopted social-distancing restrictions in March and April of 2020, though policies varied both in timing and scope. Compared to states with Democratic governors, those with Republican governors often adopted measures for shorter durations and with greater resistance from their residents. In Kentucky, an extremely close gubernatorial election immediately prior to the discovery of SARS-CoV-2 replaced a Republican incumbent with a Democrat, despite Republicans easily winning all other statewide races. This chance election result offers a unique opportunity to examine the impact of early social distancing policies in a relatively conservative, rural, white-working-class state. Our study begins by estimating an event-study model to link adoption of several common social distancing measures-public school closures, bans on large gatherings, closures of entertainment-related businesses such as restaurants, and shelter-in-place orders (SIPOs)-to the growth rate of cases across counties in the Midwest and South in the early stages of the pandemic. These policies combined to slow the daily growth rate of COVID-19 cases by 9 percentage points after 16 days, with SIPOs and entertainment establishment closures accounting for the entire effect. In order to obtain results with more direct applicability to Kentucky, we then estimate a model that interacts the policy variables with a "white working class" index characterized by political conservatism, rurality, and high percentages of white, evangelical Christian residents without college degrees. We find that the effectiveness of early social distancing measures decreased with higher values of this index. The results imply that the restrictions combined to slow the spread of COVID-19 by 12 percentage points per day in Kentucky's two largest urban counties but had no statistically detectable effect across the rest of the state.

INTRODUCTION: Kentucky is recognized as the state with the highest lung cancer burden for more than 2 decades, but how lung cancer differs in Kentucky relative to other US populations is not fully understood. PATIENTS AND METHODS: We examined lung cancer reported to the Surveillance, Epidemiology, and End Results (SEER) Program by Kentucky and the other SEER regions for patients diagnosed between 2012 and 2016. Our analyses included histologic types, incidence rates, stage at diagnosis, and survival in Kentucky and Appalachian Kentucky relative to other SEER regions. RESULTS: We found that both squamous cell carcinomas and small-cell lung cancers represent larger proportions of lung cancer diagnoses in Kentucky and Appalachian Kentucky than they do in the SEER registries. Furthermore, age-adjusted cancer incidence rates were higher in Kentucky for every subtype of lung cancer examined. Most notably, for Appalachian women the rate of small-cell carcinomas was 3.5-fold higher, and for Appalachian men the rate of squamous cell carcinoma was 3.1-fold higher, than the SEER rates. In Kentucky, lung cancers were diagnosed at later stages and lung cancer survival was lower for adenocarcinoma and neuroendocrine carcinomas than in SEER registries. Squamous cell carcinomas and small-cell carcinomas were most lethal in Appalachian Kentucky. CONCLUSION: Together, these data highlight the considerable disparities among lung cancer cases in the United States and demonstrate the continuing high burden and poor survival of lung cancer in Kentucky and Appalachian Kentucky. Strategies to identify and rectify causes of these disparities are discussed.

PURPOSE: Because rural residents, particularly those near mining sites, are susceptible to numerous environmental health hazards, it is important to gain deeper insights into their use and trust of health information, which they may employ to help recognize symptoms, learn ways to reduce exposure, or find health care. METHODS: We surveyed residents (N = 101) of rural Kentucky, Virginia, and West Virginia to assess predictors of health information source use and trust. A project manager administered face-to-face paper and pencil questionnaires assessing demographics, health status, smoking behavior, and health information use and source trust. Bivariate correlations and ordinary least squares regressions were used to analyze the data. FINDINGS: The data suggest that rural individuals frequently use nurses, doctors, and websites to seek health information, whereas traditional media are often not their preferred channel for health information. Media sources were not found as trustworthy as interpersonal and medical health information sources. While only 13.0% of individuals in the sample said they ever turned to county or state health departments for health information, these sources were trusted more than any media source and more than friends. Moreover, living closer to active mining sites-meaning these individuals are at a higher risk of environmental health hazards-predicted even less use of traditional media and greater trust in peer sources. CONCLUSIONS: Not all sources of health information are equally used or trusted by individuals from a rural disparities population. The findings have implications for health campaign message dissemination and intervention designs targeting individuals in rural Appalachia.

A critical shortage of physicians is looming in the United States. The situation in Kentucky is especially dire, especially in rural areas. Class size constraints have resulted in the University of Kentucky College of Medicine (UK COM) unable to admit over 100 qualified Kentuckians each year. This article describes how leadership at University of Kentucky committed to addressing the state physician shortage while simultaneously strengthening relationships with critical partners through the establishment of two 4-year UK COM regional medical campuses. Based on criteria (such as a commitment to educating physicians, ample patients, sufficient willing physician preceptors, etc.), partners selected were Med Center Health, the leading health care system in southwestern Kentucky, and St. Elizabeth Healthcare, the predominant health care system in northern Kentucky. These regional campuses allow UK COM to expand its class size to 201 and total enrollment to 804, increasing from historically 70 to currently 120 graduates per year expected to practice in Kentucky. Critical to the success of this expansion is the buy-in of leadership and the Admissions Committee to consider students with a wider range of Medical College Admission Test scores. The regional clinical partners have substantially increased their teaching opportunities, with a greater ability to attract physicians. Both partners have made substantial financial contributions in support of the regional campuses. These relationships have energized UK COM engagement with its area alumni and have resulted in fewer Kentuckians referred out of state for advanced specialty care. Partnerships are also occurring with UK COM to increase graduate medical education offerings at the regional sites, fulfilling the vision of "training Kentuckians in Kentucky to practice in Kentucky."
