THE COCCIDIA SPECIES PFEIFFERINELLA ELLIPSOIDES EXHIBITS SPATIAL AND SPECIES-SPECIFIC VARIATION IN PREVALENCE AMONG FRESHWATER SNAILS.

Freshwater snails are commonly studied within the context of their role as intermediate hosts for digenetic trematodes. However, there are fundamental data deficiencies related to our understanding of directly transmitted parasites, such as coccidia, for freshwater snails. Because variation in coccidia pathogenicity and transmission among snail species likely has major impacts on snail community structure, we aimed to investigate the spatial distribution and prevalence of coccidia in several freshwater snail species throughout the Ozark and Ouachita Mountains ecoregions in Arkansas. We opportunistically collected 220 freshwater snails from 24 Ozark sites in summer 2022 and scanned fecal slides for the presence of coccidia. In summer 2023, we surveyed an additional 146 snails from 19 Ouachita sites. To test for apparent interactions among coccidia and trematodes, we scanned feces from a subset of snails (Physa and Planorbella in the Ozarks) that did not have concurrent trematode infections and from those that did. We observed oocysts that morphologically conformed to Pfeifferinella ellipsoides in 2 of the 9 snail taxa from 7 of the 43 sites. Planorbella trivolvis was infected at 2 of 6 sites in the Ozarks and 0 of 5 sites in the Ouachitas. Physa species were infected at 6 of 14 sites in the Ozarks and 0 of 12 sites in the Ouachitas. In the Ozarks, Pl. trivolvis had an overall prevalence of 0.13 (6 of 47), whereas individuals in the genus Physa had an overall prevalence of 0.08 (8 of 97). Our chi-square and Fisher exact tests revealed no significant evidence for trematode-coccidia competition or synergism within the two snail species. There were no other species infected, and we did not observe any coccidia in the snails from the Ouachitas. Our survey of 366 snails among 9 taxa and 43 sites represents the largest survey for freshwater snail coccidia to date and indicates that both Pl. trivolvis and Physa spp. may be primary hosts and/or reservoir hosts for Pf. ellipsoides in freshwater snail communities. The highly aggregated distribution of Pf. ellipsoides in northwestern Arkansas requires further investigation. Our results led to proposal of several hypotheses for additional research, including questions regarding the variation of coccidia host specificity and virulence.

SARS-CoV-2 pandemic non-pharmacologic interventions temporally associated with reduced pediatric infections due to Mycoplasma pneumoniae and co-infecting respiratory viruses in Arkansas.

Non-pharmacologic interventions (NPIs), such as universal masking, implemented during the SARS-CoV-2 pandemic have reduced respiratory infections among children. This study evaluated the impact of NPIs on Mycoplasma pneumoniae infections in children, analyzing data from two hospitals in Arkansas and examining age-related differences and co-infections with other respiratory viruses. The study was approved by the Institutional Review Board and included patients (≤18 years) with upper respiratory tract symptoms. Data generated from the FilmArray Respiratory Panel were divided into pre-NPI, NPI, and post-NPI periods for analysis. Overall test positivity rate and positivity rate interval changes were evaluated. Statistical differences were determined by Chi-square (χ2 independence) analysis. A total of 100,077 tests were performed, with a statistical increase in testing volume during the NPI and post-NPI periods. The number of positive M. pneumoniae tests decreased by 77% (77 to 18) during the NPI period, then increased by 50% (18 to 27) during the post-NPI period. Preschool and elementary school age groups had the highest number of positive tests during the study at 59 (48%) and 40 (33%), respectively. Reduced M. pneumoniae infections were consistent across age groups. Co-infections with other respiratory viruses, particularly human rhinovirus/enterovirus, were observed at much lower levels. Pediatric M. pneumoniae infections in Arkansas were temporally associated with implementation and discontinuation of NPIs. Specific viral co-infections still occurred, albeit at lower levels during the SARS-CoV-2 pandemic. Because of the slower growth of this bacterium, we expect M. pneumoniae infections to return to pre-pandemic levels within approximately 2 years. IMPORTANCE: Non-pharmacologic interventions (NPIs) effectively curtailed the spread of SARS-CoV-2 and, fortuitously, many other aerosol-transmitted respiratory pathogens. This study included the largest data set of symptomatic, pediatric patients from within the United States spanning a period from November 2017 through December 2023, and encompassed individuals residing in both rural and urban settings. We observed a strong correlation between the implementation and cessation of NPIs with the rate of respiratory infections due to Mycoplasma pneumoniae and viral co-infections. These infections are returning to baseline levels approximately 2 years following NPI cessation. This observation was not unexpected since the replication time for viruses is exponentially faster than that of bacteria. The resurgence of M. pneumoniae and likely other atypical bacterial pathogens is currently in process. Healthcare providers should strongly consider these pathogens in individuals presenting with respiratory tract illnesses.

Providers' Perspectives of a Culturally Adapted CenteringPregnancy Intervention for Marshallese Women in Arkansas.

OBJECTIVE: To explore health care providers' perspectives on the successes, challenges, and suggestions for future directions regarding the implementation of CenteringPregnancy for Marshallese women in Arkansas. DESIGN: A descriptive qualitative design was used as an exploratory method. SETTING/LOCAL PROBLEM: This study took place in northwest Arkansas. Arkansas is home to the largest Marshallese Pacific Islander population in the United States. Marshallese Pacific Islanders residing in the United States have disproportionally high rates of poor maternal and infant health outcomes, even compared to other Pacific Islanders. PARTICIPANTS: Seven CenteringPregnancy providers from the University of Arkansas for Medical Sciences Northwest. INTERVENTION/MEASUREMENTS: Individual interviews were conducted from February to March of 2023. Data were managed using MAXQDA12 software. Content analysis was used to analyze the data. Initial coding was completed to identify each data segment with short summations of emergent themes. The focused thematic codes that emerged were used to identify and develop the most salient thematic categories of the data, which became the thematic codes. RESULTS: Three overarching themes emerged: Implementation Successes, Challenges to Implementation, and Future Suggestions to Improve Implementation and Sustainability. Each theme had representative subthemes. CONCLUSION: Findings provide insight for future implementation of CenteringPregnancy for Marshallese and other Pacific Islander individuals.

CHARACTERIZATION OF EIMERIA LANCASTERENSIS AND EIMERIA ONTARIOENSIS (APICOMPLEXA: EIMERIIDAE) FOUND IN EASTERN GRAY SQUIRRELS, SCIURUS CAROLINENSIS (RODENTIA: SCIURIDAE), FROM ARKANSAS AND OKLAHOMA.

We report the morphological characteristics of oocysts of Eimeria lancasterensisJoseph, 1969, collected from 6 of 6 (100%) eastern gray squirrels, Sciurus carolinensis, collected in Arkansas (n = 3) and Oklahoma (n = 3), and Eimeria ontarioensisLee and Dorney, 1971, recovered from an individual of S. carolinensis from Arkansas. Oocysts of E. lancasterensis were ovoidal to ellipsoidal, measuring (L × W) 24.0 × 14.6 (18-29 × 12-16) µm; shape index (L/W) was 1.6 (1.3-1.8). A micropyle and an oocyst residuum were absent, but up to 2 polar granules were present. Oocysts of E. ontarioensis were piriform and measured 40.6 × 26.0 (37-44 × 23-28); L/W was 1.6 (1.5-1.7). These oocysts possessed a distinct micropyle and rarely a polar granule but lacked an oocyst residuum. The DNA was isolated from both eimerians, and the 18S rDNA genetic markers were PCR-amplified, cloned, sequenced, and analyzed. To our knowledge, this study represents the first time 18S DNA sequence data have been generated from E. lancasterensis and E. ontarioensis found in North American sciurid hosts, as well as new geographic distribution records for these coccidians. In addition, we also include a tabular summary of these 2 species of Eimeria from Sciurus spp. worldwide, with information on their hosts, distribution, and taxonomically important morphological characteristics, including key measurements of oocysts and sporocysts.

Design and Impact of a Novel Rural Hospital Alliance.

Without rural hospitals, many patients may not have access to essential services, or even any health care. Rural hospitals provide a community hub for local access to primary care and emergency services, as well as a bridge to specialized care outside the community. The goal of this review was to demonstrate how the University of Arkansas for Medical Sciences supports and empowers rural hospitals through an alliance that provides cost savings through clinical networks, collaborative purchasing, and leveraged services; workforce recruitment and education; telemedicine and distance learning; community outreach; and access to best practices, resources, and tools for hospital transformation. Born out of grassroots efforts in the rural US South, this model alliance, the Arkansas Rural Health Partnership, with the University of Arkansas for Medical Sciences supporting as an academic medical center participant, offers resources and programs intended to help rural hospitals and healthcare providers survive and even thrive in the challenging landscape that is forcing many other rural hospitals to close. The Arkansas Rural Health Partnership model is relevant for rural states that are seeking to develop or reenvision rural hospital alliances with academic medical centers to the benefit of the hospitals and the health of their communities and state.

Flow cytometric assessments of metabolic activity in bacterial assemblages provide insight into ecosystem condition along the Buffalo National River, Arkansas.

The Buffalo National River (BNR), on karst terrain in Arkansas, is considered an extraordinary water resource. Water collected in Spring 2017 along BNR was metagenomically analyzed using 16S rDNA, and for 17 months (5/2017-11/2018), bacterial responses were measured in relation to nutrients sampled along a stretch of BNR near a concentrated animal feed operation (CAFO) on Big Creek. Because cell count and esterase activity can increase proportionally with organic enrichment, they were hypothesized to be elevated near the CAFO. Counts (colony forming units; CFUs) were different among sites for 73 % of the months; Big Creek generated highest CFUs 27 % of the time, with the closest downstream site at 13.3 %. Esterase activity was different among sites 94 % of the time, with Big Creek exhibiting lowest activity 71 % of the time. Over the months, activity was similar across sites at ~70 % active, except at Big Creek (56 %). The α-diversity of BNR microbial consortia near a wastewater treatment plant (WWTP) and the CAFO was related to distance from the WWTP and CAFO. The inverse relationship between high CFUs and low esterase activity at Big Creek (r = -0.71) actuated in vitro exposures of bacteria to organic wastewater contaminants (OWC) previously identified in the watershed. Exponential-phase Escherichia coli (stock strain), Streptococcus suis (avirulent, from swine), and S. dysgalactiae (virulent, from silver carp, Hypophthalmichthys molitrix) were incubated with atrazine, pharmaceuticals (17 α-ethynylestradiol and trenbolone), and antimicrobials (tylosin and butylparaben). Bacteria were differentially responsive. Activity varied with exposure time and OWC type, but not concentration; atrazine decreased it most. Taken together - the metagenomic taxonomic similarities along BNR, slightly higher bacterial growth and lower bacterial esterase at the CAFO, and the lab exposures of bacterial strains showing that OWC altered metabolism - the results indicated that bioactive OWC entering the watershed can strongly influence microbial processes in the aquatic ecosystem.

A NEW SPECIES OF THELOHANELLUS (CNIDARIA: MYXOSPOREA: MYXOBOLIDAE) FROM THE GILL OF QUILLBACK, CARPIODES CYPRINUS (CYPRINIFORMES: CATOSTOMIDAE), FROM THE ARKANSAS RIVER DRAINAGE OF OKLAHOMA.

During May 2022 and again in March 2023, 5 quillbacks, Carpiodes cyprinus, were collected from the Verdigris River, Wagoner County, Oklahoma (n = 1), and the Black River, Lawrence County, Arkansas (n = 4), and their gill, gallbladder, fins, integument, musculature, and other major organs were macroscopically examined for myxozoans. Gill lamellae from the single quillback from the Verdigris River was infected with a new myxozoan, Thelohanellus oklahomaensis n. sp. Qualitative and quantitative morphological data were obtained from fresh and formalin-fixed preserved myxospores, and molecular data consisted of a 1,767 base pair sequence of the partial small subunit (SSU) ribosomal RNA gene. Phylogenetic analysis grouped T. oklahomaensis n. sp. with myxozoans known to infect North American catostomids and Eurasian cyprinids. Histological examination localized plasmodia to an intralamellar developmental site and revealed a possible vestige of a second polar capsule. Although plasmodia markedly expanded lamellae, there were no associated epithelial or inflammatory changes. Thelohanellus oklahomaensis n. sp. is the only member of the genus known to infect the gills of C. cyprinus.

A snapshot of SARS-CoV-2 viral RNA throughout wastewater treatment plants in Arkansas.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread the viral RNA in wastewater by the feces of those experience COVID-19 symptoms. While wastewater monitoring of SARS-CoV-2 in the raw sewage has been confirmed as an effective tool to predict COVID-19 infection, the goal of this study is to assess the presence of SARS-CoV-2 viral RNA throughout various wastewater treatment processes. Wastewater samples were collected from wastewater treatment plants (WWTPs) in the state of Arkansas from August 2020 to June 2021 and measured for the relative concentration of SARS-CoV-2 viral RNA using RT-qPCR. The gene concentrations in the raw wastewater measured in this study were similar to other published studies, targeting the N1 and N2 genes of the virus. The viral RNA concentration was measured after each wastewater treatment step within WWTPs, including primary sedimentation, activated sludge, filtration and disinfection. Results show the most viral RNA removal occurred in the secondary treatment (activated sludge). The viral RNA was only occasionally detected after disinfection (chlorination or UV disinfection). Overall, WWTPs can remove the SARS-CoV-2 viral RNA at an average of 98.7%, while complete removal was achieved on 82% of the sampling days. Further investigation is required to ensure complete viral RNA removal from wastewater such as improving existing treatment process or supplementing with additional treatment steps. PRACTITIONER POINTS: The viral RNA of SARS-CoV-2 was detected in Arkansas wastewater treatment plants. SARS-CoV-2 was rarely detected in treated effluent from wastewater treatment plants. Activated sludge was effective removing SARS-CoV-2 viral RNA from wastewater. This study was limited by the direct RNA extraction from wastewater, which lowered the sensitivity of detection.

Changes in Capacity Building and Sustained Implementation Among a Statewide Coalition to Address Racial/Ethnic COVID-19 Disparities.

This article describes Arkansas Community Engagement Alliance Against COVID-19 Disparities (CEAL) Coalition initiatives and changes in measures of organizational capacity and sustainability via two waves of surveys. The Arkansas CEAL Coalition used several initiatives to address racial/ethnic COVID-19 disparities by building the capacity of community-based organizations and businesses to increase COVID-19 protective behaviors among their clients. Our study can inform future strategies that use a community-engaged coalition structure to reduce disparities among communities that suffer disproportionately from COVID-19. (Am J Public Health. (Am J Public Health. 2024;114(S1):S59-S64. https://doi.org/10.2105/AJPH.2023.307470).

Characteristics and Outcomes of Women and Infants Who Received Prenatal Care While Incarcerated in Arkansas State Prison System, 2014-2019.

BACKGROUND: Prisons face challenges in meeting the unique health care needs of women, especially those who are pregnant. This retrospective chart review sought to describe the maternal and infant health outcomes of incarcerated women who received prenatal care while in an Arkansas prison. METHODS: Using a hospital-based electronic medical records (EMR) system, we examined the maternal health history and current pregnancy characteristics of 219 pregnant women who received prenatal care while incarcerated from June 2014 to May 2019. We also examined labor and delivery characteristics and postpartum and infant birth outcomes for the 146 women from this cohort who delivered a living child while still incarcerated. RESULTS: Most records indicated complex health histories with several chronic illnesses, mental health diagnoses, history of substance use, and lifetime medical complications. Despite comorbid illness, substance use disorder (SUD), trauma-history, and post-traumatic stress disorder (PTSD) prevalence was lower than expected. Previous and current obstetrical complications were common. Although the Neonatal Intensive Care Unit (NICU) admission rate (41%) was high, few infants required extensive treatment intervention. Postpartum complications were rare; however, a small portion of women who gave birth in custody experienced severe complications and were re-admitted to the hospital post-discharge. CONCLUSIONS: Incarcerated pregnant women and their infants are a marginalized population in great need of health care advocacy. To optimize maternal-infant outcomes, carceral agencies must recognize the health needs of incarcerated pregnant women and provide appropriate prenatal care. Expansion of carceral perinatal care to include screening for SUD and psychiatric symptoms (e.g., PTSD) and referral to appropriate care is highly encouraged. Policies related to NICU admission for non-medical reasons should be further examined.

Characterization of QoI-Fungicide Resistance in Cercospora Isolates Associated with Cercospora Leaf Blight of Soybean from the Southern United States.

Cercospora leaf blight (CLB) of soybean, caused by Cercospora cf. flagellaris, C. kikuchii, and C. cf. sigesbeckiae, is an economically important disease in the southern United States. Cultivar resistance to CLB is inconsistent; therefore, fungicides in the quinone outside inhibitor (QoI) class have been relied on to manage the disease. Approximately 620 isolates from plants exhibiting CLB were collected between 2018 and 2021 from 19 locations in eight southern states. A novel polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay based on two genes, calmodulin and histone h3, was developed to differentiate between the dominant species of Cercospora, C. cf. flagellaris, and C. cf. sigesbeckiae. A multilocus phylogenetic analysis of actin, calmodulin, histone h3, ITS rDNA, and transcription elongation factor 1-α was used to confirm PCR-RFLP results and identify remaining isolates. Approximately 80% of the isolates collected were identified as C. cf. flagellaris, while 15% classified as C. cf. sigesbeckiae, 2% as C. kikuchii, and 3% as previously unreported Cercospora species associated with CLB in the United States. PCR-RFLP of cytochrome b (cytb) identified QoI-resistance conferred by the G143A substitution. Approximately 64 to 83% of isolates were determined to be QoI-resistant, and all contained the G143A substitution. Results of discriminatory dose assays using azoxystrobin (1 ppm) were 100% consistent with PCR-RFLP results. To our knowledge, this constitutes the first report of QoI resistance in CLB pathogen populations from Alabama, Arkansas, Kentucky, Mississippi, Missouri, Tennessee, and Texas. In areas where high frequencies of resistance have been identified, QoI fungicides should be avoided, and fungicide products with alternative modes-of-action should be utilized in the absence of CLB-resistant soybean cultivars.

Predicting pediatric severe asthma exacerbations: an administrative claims-based predictive model.

OBJECTIVE: Previous machine learning approaches fail to consider race and ethnicity and social determinants of health (SDOH) to predict childhood asthma exacerbations. A predictive model for asthma exacerbations in children is developed to explore the importance of race and ethnicity, rural-urban commuting area (RUCA) codes, the Child Opportunity Index (COI), and other ICD-10 SDOH in predicting asthma outcomes. METHODS: Insurance and coverage claims data from the Arkansas All-Payer Claims Database were used to capture risk factors. We identified a cohort of 22,631 children with asthma aged 5-18 years with 2 years of continuous Medicaid enrollment and at least one asthma diagnosis in 2018. The goal was to predict asthma-related hospitalizations and asthma-related emergency department (ED) visits in 2019. The analytic sample was 59% age 5-11 years, 39% White, 33% Black, and 6% Hispanic. Conditional random forest models were used to train the model. RESULTS: The model yielded an area under the curve (AUC) of 72%, sensitivity of 55% and specificity of 78% in the OOB samples and AUC of 73%, sensitivity of 58% and specificity of 77% in the training samples. Consistent with previous literature, asthma-related hospitalization or ED visits in the previous year (2018) were the two most important variables in predicting hospital or ED use in the following year (2019), followed by the total number of reliever and controller medications. CONCLUSIONS: Predictive models for asthma-related exacerbation achieved moderate accuracy, but race and ethnicity, ICD-10 SDOH, RUCA codes, and COI measures were not important in improving model accuracy.

Using focused ethnography to inform biomedical research infrastructure enhancement at primarily undergraduate institutions.

The National Institutes of Health (NIH) supports 24 IDeA Networks of Biomedical Research Excellence (INBRE) Programs that help develop university-based biomedical research capacity in states that historically receive low levels of extramural grant support. To assess the effectiveness of the Arkansas INBRE in meeting its biomedical research capacity-building goals, we evaluated how the context (i.e., local and institutional settings) at two undergraduate institutions impacted variability in science faculty use of program resources. Data were collected by in-depth interviews with faculty and administrators (N = 9), focused observations, a review of Arkansas INBRE databases, and internet searches. Content analysis was used to code interview transcripts and field notes, and then qualitative data were integrated with data from databases and internet searches to construct two institutional case summaries. Constant comparison was used to identify similarities and differences between the institutions that helped to explain variability in how frequently faculty used Arkansas INBRE resources, including an enrollment crisis at undergraduate institutions in the United States and the presence or absence of a robust research culture at each institution. These findings were used to suggest program improvements (e.g., classroom-based research) that could further strengthen biomedical research capacity in Arkansas. As some barriers to program effectiveness are likely found in other IDeA-eligible states, improvements suggested for the Arkansas INBRE could apply to INBRE programs elsewhere.NEW & NOTEWORTHY This article describes results from an approach to program evaluation (i.e., focused ethnography) that has not been previously used to evaluate grant mechanisms. This "experience near" approach, which involved qualitative interviews and firsthand observations, lent valuable insights into how broader and institutional contexts at two primarily undergraduate institutions hindered or facilitated use of Arkansas INBRE resources. The insights gained can be used to enhance the Arkansas INBRE, which aims to strengthen the statewide biomedical infrastructure.

Racial and Ethnic Disparities in Tuberculosis Incidence, Arkansas, USA, 2010-2021.

We conducted an epidemiologic assessment of disease distribution by race/ethnicity to identify subpopulation-specific drivers of tuberculosis (TB). We used detailed racial/ethnic categorizations for the 932 TB cases diagnosed in Arkansas, USA, during 2010-2021. After adjusting for age and sex, racial/ethnic disparities persisted; the Native Hawaiian/Pacific Islander (NHPI) group had the highest risk for TB (risk ratio 173.6, 95% CI 140.6-214.2) compared with the non-Hispanic White group, followed by Asian, Hispanic, and non-Hispanic Black. Notable racial/ethnic disparities existed across all age groups; NHPI persons 0-14 years of age were at a particularly increased risk for TB (risk ratio 888, 95% CI 403-1,962). The risks for sputum smear-positive pulmonary TB and extrapulmonary TB were both significantly higher for racial/ethnic minority groups. Our findings suggest that TB control in Arkansas can benefit from a targeted focus on subpopulations at increased risk for TB.

Novel Ozark Orthohantavirus in Hispid Cotton Rats (Sigmodon hispidus), Arkansas, USA.

We report a novel orthohantavirus, putatively named Ozark orthohantavirus, in hispid cotton rats captured within the Ozark Plateau in Arkansas, USA. This virus phylogenetically clusters with other orthohantaviruses that cause severe human disease. Continued orthohantavirus surveillance and virus sequencing are needed to address the potential public health threat of this virus.

PREVALENCE OF EHRLICHIA AND ANAPLASMA SPP. IN TICKS COLLECTED FROM CATTLE AND DEER IN ARKANSAS, USA.

Bovine anaplasmosis, caused by Anaplasma marginale, is widespread in cattle in the southeast United States. The pathogen is biologically transmitted by Dermacentor spp. ticks, and mechanically transmitted by biting flies and via fomites. Despite high reported regional seroprevalence, Dermacentor spp. are rare on cattle in the southeast. To identify other putative An. marginale vectors, and to characterize cattle exposure to other tick-borne pathogens, we collected ticks from Arkansas cattle herds in 2020-2022. Recognizing that deer are important hosts for some of the same tick species that parasitize cattle, we also collected ticks from hunter-killed deer in the fall and winter of 2021. Ticks were screened for bacteria in the family Anaplasmataceae using qPCR. Positive samples were further amplified using a PCR assay targeting the groEL gene, and the resulting amplicons were sequenced for identification. A total of 3,794 ticks were collected, the majority of which were Amblyomma americanum. Amblyomma americanum was the most common species on cattle, and Ixodes scapularis was most common on deer. No ticks were positive for An. marginale, though Anaplasma phagocytophilum was detected in deer-collected I. scapularis, as well as in a single engorged Am. americanum from cattle. Amblyomma americanum from cattle were infected with Ehrlichia ewingii, Ehrilichia chaffeensis, and Panola Mountain Ehrlichia. Cattle in Arkansas are exposed to several ehrlichial pathogens and may also be exposed to An. phagocytophilum. The importance of these pathogens, particularly Panola Mountain Ehrlichia, in causing cattle disease in Arkansas deserves further study, as does the importance of mechanical transmission of An. marginale in bovine anaplasmosis epidemiology.

Private Landowners' Perspectives on Feral Swine and Regulation-Evidence from Arkansas, Louisiana, and East Texas.

Feral swine (FS) (Sus scrofa) are an invasive species that has spread widely across the southern United States, including the West Gulf region. With their rapidly increasing population, they have caused severe damage to landowners. To better understand private landowners' knowledge and attitudes toward FS, we conducted a mail survey in the West Gulf region including Arkansas, Louisiana, and East Texas in 2021. The results indicated that the majority of landowners are familiar with, have overall negative opinions of, and are concerned about the presence and future population growth of FS in this region. Nearly 70% of the private landowners surveyed supported stricter FS control regulations. Logistic regression results further revealed that landowners' supportiveness for FS control regulations is associated with their perceived FS-induced economic damage and ownership characteristics (i.e., age and tenure). These findings shed new light on private landowners' perspectives on FS invasions and control regulations, aiding in developing and implementing FS control/management policies and programs in the West Gulf region and beyond.

Correlates of COVID-19 vaccine coverage in Arkansas: Results from a weighted random sample survey.

We assessed COVID-19 vaccination (≥1 dose) status as influenced by sociodemographic factors (i.e., age, gender, race/ethnicity, education, income, and parent or guardian status), healthcare provider recommendation, and personal vaccine hesitancy among Arkansas residents in October 2022. We asked: did the likelihood of vaccination differ across sociodemographic groups of Arkansas during this period of the pandemic? Is COVID-19 vaccination associated with recommendations from healthcare providers and/or COVID-19 vaccine hesitancy? We analyzed data from a random sample survey of adults in Arkansas (N = 2,201). Three in four adults self-reported vaccination against COVID-19 in October 2022. We found both positive and negative association between COVID-19 vaccination and age, gender, race/ethnicity, education, income, healthcare provider recommendation, and vaccine hesitancy. We highlight racial differences in COVID-19 coverage and the higher odds of COVID-19 vaccination among Black adults compared to White adults in particular, which has broad implications for the study of vaccine coverage and hesitancy. We also discuss implications of our findings regarding healthcare provider recommendations to be vaccinated against COVID-19.

Rural and Agricultural Natural Disaster Stress and Recovery: A Comparison.

This study used a novel survey instrument to evaluate the hypothesis that U.S. agricultural producers have significantly different stress and recovery experiences following acute-onset natural disaster compared to their non-agricultural counterparts. Participants were recruited through local organizations and targeted email and social media in communities in Arkansas and Nebraska that had experienced violent tornadoes in 2014 and/or severe flooding in 2019. The survey instrument incorporated the Brief Resilience Scale, the Revised Impact of Event Scale referencing two time points, the Posttraumatic Growth Inventory-Short Form, and original questions. Demographic, exposure, stress, and recovery measures were analyzed in SAS with Chi-square tests, t-tests, Wilcoxon tests, and multiple linear regression modeling to test for differences between agricultural and non-agricultural groups in resilience, event exposure, stress symptoms in the week after the event, stress symptoms in the month before the survey, a calculated recovery ratio, and posttraumatic growth. Analysis sample (N = 159) contained 20.8% agricultural occupation, 71.1% female, and 49.1% over age 55. No significant differences were found between agricultural and non-agricultural participants when comparing resilience, stress, or recovery ratio measures. Unadjusted posttraumatic growth score was significantly lower in the agriculture group (P = .02), and an occupation group by sex interaction was significantly associated with posttraumatic growth score (P = .02) when controlled for number of initial posttraumatic stress symptoms in the adjusted model, with agricultural women showing lower growth. Overall, there was no evidence of significant difference in disaster stress and recovery between agricultural and rural, non-agricultural groups in this study. There was some evidence that women in agriculture may have lower levels of recovery. Data indicated that rural residents continue to experience posttraumatic-type symptoms up to 8 years beyond the acute-onset natural disaster events. Communities should include strategies to support mental and emotional health in their preparedness, response, and recovery plans with intentional inclusion of agricultural populations.
