Beneficiary Experience of Care by Level of Integration in Dual Eligible Special Needs Plans.

Importance: Dual Eligible Special Needs Plans (D-SNPs) are private managed care plans designed to promote Medicare and Medicaid integration for full-benefit, dually eligible beneficiaries. Currently, the highest level of D-SNP integration occurs in plans with exclusively aligned enrollment (EAE). Objective: To compare patient experience of care, out-of-pocket spending, and satisfaction among dually enrolled Medicaid beneficiaries in D-SNPs with EAE, those in D-SNPs without EAE, and those with traditional Medicare. Design, Setting, and Participants: This cross-sectional study included respondents to a mail survey fielded to a stratified random sample of full-benefit, community-dwelling, dual-eligible Medicaid beneficiaries who qualified for receipt of home and community-based services in the Virginia Medicaid Commonwealth Coordinated Care Plus program between March and October 2022. Exposure: Enrollment in a D-SNP with EAE or a D-SNP without EAE vs traditional Medicare. Main Outcomes and Measures: The main outcomes were self-reported measures of access and delays in receiving plan approvals, out-of-pocket spending, and satisfaction with health plans' customer service and choice of primary care and specialist physicians. Results: Of 7200 surveys sent, 2226 were completed (response rate, 30.9%). The analytic sample consisted of 1913 Medicaid beneficiaries with nonmissing data on covariates (mean [SD] age, 70.8 [15.6] years; 1367 [71.5%] female). Of these, 583 (30.5%) were enrolled in D-SNPs with EAE, 757 (39.6%) in D-SNPs without EAE, and 573 (30.0%) in traditional Medicare. Compared with respondents enrolled in D-SNPs without EAE, those in D-SNPs with the highest level of integration (EAE) were 6.77 percentage points (95% CI, 8.81-12.66 percentage points) more likely to report being treated with courtesy and respect and 5.83 percentage points (95% CI, 0.21-11.46 percentage points) more likely to know who to call when they had a health problem. No statistically significant differences were found between members in either type of D-SNP and between those in D-SNPs and traditional Medicare in terms of their difficulty accessing care, delays in care, and satisfaction with care coordination and physician choice. Conclusions and Relevance: This cross-sectional study found some benefits of integrating administrative processes under Medicare and Medicaid but suggests that care coordination and access improvements under full integration require additional time and/or efforts to achieve.

Self-Reported Religiosity and Spirituality of Registered Nurses in Virginia.

ABSTRACT: The professional nurse cares for an increasingly diverse population, varying in ethnicity, culture, and faith beliefs that influence health and wellness. The moral obligation of the nurse to provide individualized, holistic care of clients includes spiritual care. Supported by the Agape Model of Nursing, nurses should understand their personal religiosity and its impact on the care they provide. The purpose of this study was to better understand the self-reported religiosity and spirituality of registered nurses licensed to practice in the Commonwealth of Virginia.

Margalefidinium polykrikoides dinoflagellate blooms increase mortality of Acartia tonsa copepods.

Previous research on phytoplankton blooms has often focused on the initiation of blooms, while studies on the mechanisms underlying bloom decline and termination have been more limited. This study aimed to explore the extent of which Acartia tonsa (copepod) grazing does or does not contribute to Margalefidinium polykrikoides (dinoflagellate) bloom decline. M. polykrikoides is a prominent harmful algal bloom (HAB) species that forms dense blooms in coastal and estuarine systems around the world with known ichthyotoxic effects. Sampling occurred in the lower York River Estuary, Virginia, USA in 2021 and 2022 during two M. polykrikoides blooms. Prey removal experiments were conducted using organisms collected from the field to estimate A. tonsa ingestion rates on M. polykrikoides. While A. tonsa was capable of ingesting M. polykrikoides at low abundance, when M. polykrikoides abundance exceeded 2000 cells mL-1, A. tonsa experienced nearly 100% mortality in the 24-hour prey removal experiments. This suggests that A. tonsa likely cannot exert any top-down control on M. polykrikoides blooms, rather, at high concentrations, M. polykrikoides may act as its own grazing deterrent. Extensive M. polykrikoides blooms could therefore continue to persist due to a reduction in grazing pressure, rather than an increase. This would suggest that the decline of M. polykrikoides blooms is likely caused by another factor. As the frequency, duration, and magnitude of HABs are expected to increase in the future, these findings provide key insights to the trophic interactions that may be influencing the duration of M. polykrikoides blooms.

Differing Within-Household Food Security Statuses Are Associated with Varied Maternal Mental Health Outcomes.

Household food insecurity is not necessarily equally experienced by all household members, with mothers often changing their intake first when food resources are limited. The purpose of this study was to understand the association between maternal mental health and intrahousehold differences in food security statuses. A cross-sectional survey was administered to Virginia mothers with low income (August-October 2021), assessing validated measures of food security, mental and physical health and related factors. Participants (n = 570) were grouped according to the food security status of adults and children within the household. Linear regression was used to assess the outcomes of interest by group and controlled for key demographic variables. Mothers in households with any food insecurity reported worse overall mental health and used 3-4 more food coping strategies than households experiencing food security (p < 0.05). Only mothers in households where adults experienced food insecurity reported significantly greater anxiety and depressive symptoms (61.5 and 58.1, respectively) compared to households experiencing food security (55.7 and 52.4, p < 0.001). While any experience of household food insecurity is associated with worse maternal mental health, there were differences by the within-household food security status. Future research should explore screening measures that capture specific household members' food security to connect households with available resources.

Quantitative microbiome profiling of honey bee (Apis mellifera) guts is predictive of winter colony loss in northern Virginia (USA).

For the past 15 years, the proportion of honey bee hives that fail to survive winter has averaged ~ 30% in the United States. Winter hive loss has significant negative impacts on agriculture, the economy, and ecosystems. Compared to other factors, the role of honey bee gut microbial communities in driving winter hive loss has received little attention. We investigate the relationship between winter survival and honey bee gut microbiome composition of 168 honey bees from 23 hives, nine of which failed to survive through winter 2022. We found that there was a substantial difference in the abundance and community composition of honey bee gut microbiomes based on hive condition, i.e., winter survival or failure. The overall microbial abundance, as assessed using Quantitative Microbiome Profiling (QMP), was significantly greater in hives that survived winter 2022 than in those that failed, and the average overall abundance of each of ten bacterial genera was also greater in surviving hives. There were no significant differences in alpha diversity based on hive condition, but there was a highly significant difference in beta diversity. The bacterial genera Commensalibacter and Snodgrassella were positively associated with winter hive survival. Logistic regression and random forest machine learning models on pooled ASV counts for the genus data were highly predictive of winter outcome, although model performance decreased when samples from the location with no hive failures were excluded from analysis. As a whole, our results show that the abundance and community composition of honey bee gut microbiota is associated with winter hive loss, and can potentially be used as a diagnostic tool in evaluating hive health prior to the onset of winter. Future work on the functional characterization of the honey bee gut microbiome's role in winter survival is warranted.

Freshwater mussels prefer a diet of stramenopiles and fungi over bacteria.

Freshwater mussels (Mollusca: Unionidae) play a crucial role in freshwater river environments where they live in multi-species aggregations and often serve as long-lived benthic ecosystem engineers. Many of these species are imperiled and it is imperative that we understand their basic needs to aid in the reestablishment and maintenance of mussel beds in rivers. In an effort to expand our knowledge of the diet of these organisms, five species of mussel were introduced into enclosed systems in two experiments. In the first, mussels were incubated in water from the Clinch River (Virginia, USA) and in the second, water from a manmade pond at the Commonwealth of Virginia's Aquatic Wildlife Conservation Center in Marion, VA. Quantitative PCR and eDNA metabarcoding were used to determine which planktonic microbes were present before and after the introduction of mussels into each experimental system. It was found that all five species preferentially consumed microeukaryotes over bacteria. Most microeukaryotic taxa, including Stramenopiles and Chlorophytes were quickly consumed by all five mussel species. We also found that they consumed fungi but not as quickly as the microalgae, and that one species of mussel, Ortmanniana pectorosa, consumed bacteria but only after preferred food sources were depleted. Our results provide evidence that siphon feeding Unionid mussels can select preferred microbes from mixed plankton, and mussel species exhibit dietary niche differentiation.

Passive biomonitoring for per- and polyfluoroalkyl substances using invasive clams, C. fluminea.

Per- and polyfluoroalkyl substances (PFAS) are a class of toxic manufactured chemicals in commercial and consumer products. They are resistant to environmental degradation and mobile in soil, air, and water. This study used the introduced bivalve Corbicula fluminea as a passive biomonitor at sampling locations in a primary drinking water source in Virginia, USA. Many potential PFAS sources were identified in the region. Perfluorohexane sulfonate (PFHxS) and 6:2 fluorotelomer sulfonic acid (6:2 FTS) levels were highest downstream of an airport. The highest levels of short-chain carboxylic acids were in locations downstream of a wastewater treatment plant. Measured PFAS concentrations varied by location in C. fluminea, sediment, and surface water samples. Two compounds were detected across all three mediums. Calculated partitioning coefficients confirm bioaccumulation of PFAS in C. fluminea and sorption to sediment. C. fluminea bioaccumulated two PFAS not found in the other mediums. Perfluoroalkyl carboxylic acids and short-chain compounds dominated in clam tissue, which contrasts with findings of accumulation of longer-chain and perfluorosulfonic acids in fish. These findings suggest the potential for using bivalves to complement other organisms to better understand the bioaccumulation of PFAS and their fate and transport in a freshwater ecosystem.

From Research to Roach Traps: Practical Considerations for a Home-Based Asthma Program.

CONTEXT: Home-based asthma interventions have a significant evidence base as an effective means to address moderate and severe breathing concerns triggered by home conditions. However, the literature lacks logistical and staffing considerations necessary to successfully implement such a program at a governmental level. This practice report and process evaluation outlines practical details and lessons learned during a healthy homes pilot, and how they were addressed in the design of a permanent program. OBJECTIVE: To inform the creation of a permanent home-based asthma intervention at the Alexandria Health Department (AHD) (City of Alexandria, Virginia) and understand the tools and resources necessary for success. INTERVENTION: Participating households received a health and environmental assessment, followed by cleaning supplies, relevant education, and referrals to partners for services. AHD staff tracked challenges and insights at each step of the intervention. At the end of the pilot, staff worked with the community to identify solutions and design a permanent program. CONCLUSIONS: Although the pilot model was constructed based on existing case studies, technical assistance from national experts, and guidance documents, the team still experienced challenges around recruitment, staff support, home visit implementation, and impact evaluation. While pilots and existing literature can be instructive for identifying issues, work with residents and partners to develop a uniquely tailored community program was essential for practical success. IMPLICATIONS ON POLICY AND PRACTICE: Health departments developing new initiatives should consider both the staff and participant experience throughout the creation of administrative and programmatic processes. Testing out draft versions of these processes and materials using internal and external focus groups can identify potential bottlenecks and solutions upfront.

Incidence of per- and polyfluoroalkyl substances (PFAS) in private drinking water supplies in Southwest Virginia, USA.

Per- and polyfluoroalkyl substances (PFAS) are a class of man-made contaminants of human health concern due to their resistance to degradation, widespread environmental occurrence, bioaccumulation in living organisms, and potential negative health impacts. Private drinking water supplies may be uniquely vulnerable to PFAS contamination in impacted areas, as these systems are not protected under federal regulations and often include limited treatment or remediation, if contaminated, prior to use. The goal of this study was to determine the incidence of PFAS contamination in private drinking water supplies in two counties in Southwest Virginia, USA (Floyd and Roanoke) that share similar bedrock geologies, are representative of different state Department of Health risk categories, and to examine the potential for reliance on citizen-science based strategies for sample collection in subsequent efforts. Samples for inorganic ions, bacteria, and PFAS analysis were collected on separate occasions by participants and experts at the home drinking water point of use (POU) for comparison. Experts also collected outside tap samples for analysis of 30 PFAS compounds. At least one PFAS was detectable in 95 % of POU samples collected (n = 60), with a mean total PFAS concentration of 23.5 ± 30.8 ppt. PFOA and PFOS, two PFAS compounds which presently have EPA health advisories, were detectable in 13 % and 22 % of POU samples, respectively. On average, each POU sample contained >3 PFAS compounds, and one sample contained as many as 8 compounds, indicating that exposure to a mixture of PFAS in drinking water may be occurring. Although there were significant differences in total PFAS concentrations between expert and participant collected samples (Wilcoxon, alpha = 0.05), collector bias was inconsistent, and may be due to the time of day of sampling (i.e. morning, afternoon) or specific attributes of a given home. Further research is required to resolve sources of intra-sample variability.

Exploring the adoption of water quality trading as an alternative stormwater regulatory compliance strategy for land development projects: A case study for Roanoke, Virginia.

Urban stormwater runoff is a significant source of nutrient pollution that is very costly to treat. Water quality trading (WQT) is a market-based strategy that can be used to lower the costs associated with meeting stormwater quality regulations. While many WQT programs have experienced low participation, Virginia's program has seen high participation due to the inclusion of land developers and other regulated stormwater dischargers. However, the extent to which WQT is used as a compliance option by regulated stormwater dischargers is not well understood, particularly when compared with the adoption of traditional compliance options. To address this knowledge gap, we collated a novel dataset comprising site characteristics and stormwater compliance methods for all development projects in the City of Roanoke, Virginia from December 2015 to March 2022. We analyzed this dataset to characterize the adoption of nutrient offset credits and other compliance methods being used, including best management practices (BMPs) and improved land covers associated with reduced nutrient export. Results show that credits are the preferred compliance option in Roanoke and were used as the only treatment compliance method for 59% of projects with treatment requirements. Projects using credits corresponded with a lower median disturbed area (1.36 acres) and lower median nutrient load reduction requirement (0.69 pounds of total phosphorus per year) compared with other compliance methods. Furthermore, we found that 58% of the projects that used credits achieved stormwater quantity compliance using methods other than implementing stormwater control devices. By mapping buyers and sellers of credits, we found that all credit sellers are downstream of the development projects. We discuss how this downstream trading could be a cause for concern, as part of a larger discussion of the advantages of tracking stormwater compliance methods, drawing on Roanoke as a case study.

The Chickahominy T.R.U.T.H. (Trust, Research, Understand, Teach, and Heal) Project-A Tribal Community-Academic Partnership for Understanding the Impact of Structural Factors on Perceived Cancer Risk in Rural Virginia.

In 2022, the Virginia Chickahominy Indian Tribe partnered with Virginia Commonwealth University Massey Comprehensive Cancer Center to investigate concerns about a potential cancer cluster near a local landfill. While investigating cancer clusters is complex due to long latency and multifactorial causes, the community's concerns about structural factors driving cancer risk warrant exploration. Thus, the Chickahominy T.R.U.T.H. (Trust, Research, Understand, Teach, and Heal) Project was created as a community-academic partnership to (1) identify structural factors and barriers associated with perceived cancer risk and care; (2) assess cancer knowledge, care access gaps, and perceived risks, including testing private and community water sources; (3) develop and deploy culturally tailored cancer education and resource navigation, including groundwater safety education, policies, and remediation. We will conduct 150 in-person interviews and water tests among residents within a four-mile radius of the landfill, and deploy 1000 structured questionnaires among Charles City County residents. In this paper, we provide an overview of the ongoing project design, development, and progress in support of the project's objectives. This collaborative investigation aims to address cancer health disparities, enhance research and health policy advocacy, and honor the sacred knowledge of an underserved community, laying the groundwork for a long-term partnership to guide future research questions.

The chloroplast and mitochondrial genomes of two Gomphonema parvulum (Bacillariophyta) environmental isolates from South Carolina (United States) and Virginia (United States).

Gomphonema parvulum is a cosmopolitan freshwater diatom that is used as an indicator in water quality biomonitoring. In this study, we report the culturing of two geographically separated isolates from southeastern North America, their morphology, and the sequencing and assembly of their mitochondrial and chloroplast genomes. Morphologically, both strains fit G. parvulum sensu lato, but the frustules from a protected habitat in South Carolina were smaller than those cited in the historic data of this species from the same location as well as a second culture from Virginia. Phylogenetic analyses using the rbcL gene placed both within a clade with G. parvulum. Genetic markers, including full chloroplast and mitochondrial genomes and the nuclear small subunit rRNA gene region were assembled from each isolate. The organellar genomes of the two strains varied slightly in size due to small differences in intergenic regions with chloroplast genomes of 121,035 bp and 121,482 bp and mitochondrial genomes of 34,639 bp and 34,654 bp. The intraspecific pairwise identities of the chloroplast and mitochondrial genomes of these two isolates were 97.9% and 95.4%, respectively. Multigene phylogenetic analysis demonstrated a close relationship between G. parvulum, Gomphoneis minuta, and Didymosphenia geminata.

Nutrient reduction by eastern oysters exhibits low variability associated with reproduction, ploidy, and farm location.

Enhancement of shellfish populations has long been discussed as a potential nutrient reduction tool, and eastern oyster aquaculture was recently approved as a nutrient reduction best management practice (BMP) in Chesapeake Bay, USA. This study addressed BMP-identified data gaps involving variation in nutrient concentration related to ploidy, effects of reproductive development, and a paucity of phosphorus concentration data. Diploid and triploid oysters were collected from farms in Maryland and Virginia across the typical local reproductive cycle. The nutrient concentration of tissue and shell was consistent with the currently implemented BMP. Minor variation observed in nitrogen and phosphorus concentration was within the previously reported range, for farm location, ploidy, and reproductive cycle timing. Ploidy-based differences in tissue dry weight were not observed at either farm, which contrasts with current nutrient reduction estimates. These results suggest separate crediting values for diploids and triploids may need further investigation and potential re-evaluation.

Community Health Care Providers' Perspectives on Human Immunodeficiency Virus Pre-Exposure Prophylaxis Use Among Black Women in Eastern Virginia.

The most at-risk population among women for human immunodeficiency virus (HIV) diagnosis in the United States are Black women, accounting for 61% of all new HIV cases. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention method for people at risk of HIV acquisition. Although disproportionately affected by HIV, Black women's knowledge, perceived benefits, and uptake of PrEP remain low. The socioecological model (SEM) may be useful for understanding why there is a low uptake of PrEP among Black women. The current study used the SEM to explore provider perspectives on the barriers and facilitators of PrEP uptake among Black women in Eastern Virginia. Semistructured interviews were conducted with a total sample of 15 community health care providers. Barriers of PrEP uptake at the societal (e.g., PrEP advertisements focus on gay men), community/organizational (e.g., time constraints in the workplace), interpersonal (e.g., perceived monogamy), and individual (e.g., unmet basic needs) levels were identified. Providers also identified facilitators of PrEP uptake at the societal (e.g., PrEP advertisements that target women), community/organizational (e.g., PrEP education), interpersonal (e.g., HIV-positive partner), and individual (e.g., PrEP awareness and perceived susceptibility to HIV) levels. These findings highlight unique barriers to accessing and taking PrEP for Black women in the United States, and potential factors that could facilitate PrEP use. Both barriers and facilitators may be important targets for interventions to improve PrEP uptake. Future research focused on improving PrEP uptake among Black women in the United States should consider multi-level interventions that target barriers and facilitators to reduce rates of HIV infections.

Observation of key phenological stages of hemlock woolly adelgid (Hemiptera: Adelgidae): using citizen science as a tool to inform research and management.

Increasing efficiency of data gathering at the landscape scale on the growing number of pests and pathogens threatening forests worldwide has potential to improve management outcomes. Citizen science is expanding, with growing support and utility in environmental and conservation fields. We present a case study showing how citizen science observations can be used to inform research and management of a devastating forest pest. Hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), was introduced to eastern North America, leading to decline and mortality of eastern [Tsuga canadensis (L.) Carrière] (Pinales: Pinaceae) and Carolina hemlock (Tsuga caroliniana Engelmann) trees. Management activities, most notably biological control, rely on observations of A. tsugae phenology to inform the timing of releases and monitoring surveys of their highly synchronized specialist predators. In this article, we outline a citizen science program and report phenological observations on A. tsugae. Additionally, we report data comparing A. tsugae estivation break in Virginia (VA) and New York (NY) State, revealing that estivation break is synchronized between NY and VA. This observation is supported by 6 years of citizen scientist observations, showing similar patterns throughout NY, with egg laying shown to be much more variable than estivation break.

"It's different than a doctor saying 'You're making the right choice'": A qualitative study of chaplains' experience caring for patients undergoing abortion in Washington DC, Maryland, and Virginia.

OBJECTIVES: Health care chaplains are faith providers with theological education, pastoral experience, and clinical training who provide spiritual care to patients, their families, and medical staff. This study sought to characterize chaplains' experiences providing spiritual care for patients experiencing abortion and pregnancy loss and to explore how chaplains gain competency and comfort in providing pastoral care for this patient population. STUDY DESIGN: Researchers conducted in-depth, semistructured, qualitative interviews with currently-practicing chaplains recruited via convenience sampling in the Washington DC, Maryland, and Virginia region. We analyzed interviews using directed content analysis and coded using both inductive and deductive coding. RESULTS: We interviewed 13 chaplains. The majority were Protestant and identified as Democrats. Participants often personally struggled with the acceptability of abortion but emphasized the importance of spiritual care for this patient population. They recognized that religious stigma regarding abortion prevented referrals to chaplaincy. Though desiring to contribute, chaplains reported little formal education in pregnancy support counseling. They relied on foundational pastoral care skills, like holding space, values clarification, connecting with patients' spirituality, words of comfort, ritualistic memorialization, and resource provision. All desired more training specific to abortion and pregnancy loss in chaplaincy education. CONCLUSIONS: Chaplains from varied faith backgrounds have a diverse set of skills to support patients experiencing abortion or pregnancy loss, but feel underutilized and lacking in formal training. Though not all patients require pastoral support, chaplains can be critical members of the care team, particularly for those patients experiencing spiritual distress. IMPLICATIONS: Chaplains have a paucity of training in supporting patients experiencing abortion and pregnancy loss. Chaplains want to be involved with patients experiencing abortion but feel excluded by both patients and practitioners. Standardization of pastoral care training is important to ensure adequate spiritual support for patients who desire such services.

Lung Cancer Prevalence in Virginia: A Spatial Zipcode-Level Analysis via INLA.

BACKGROUND: Examining lung cancer (LC) cases in Virginia (VA) is essential due to its significant public health implications. By studying demographic, environmental, and socioeconomic variables, this paper aims to provide insights into the underlying drivers of LC prevalence in the state adjusted for spatial associations at the zipcode level. METHODS: We model the available VA zipcode-level LC counts via (spatial) Poisson and negative binomial regression models, taking into account missing covariate data, zipcode-level spatial association and allow for overdispersion. Under latent Gaussian Markov Random Field (GMRF) assumptions, our Bayesian hierarchical model powered by Integrated Nested Laplace Approximation (INLA) considers simultaneous (spatial) imputation of all missing covariates through elegant prediction. The spatial random effect across zip codes follows a Conditional Autoregressive (CAR) prior. RESULTS: Zip codes with elevated smoking indices demonstrated a corresponding increase in LC counts, underscoring the well-established connection between smoking and LC. Additionally, we observed a notable correlation between higher Social Deprivation Index (SDI) scores and increased LC counts, aligning with the prevalent pattern of heightened LC prevalence in regions characterized by lower income and education levels. On the demographic level, our findings indicated higher LC counts in zip codes with larger White and Black populations (with Whites having higher prevalence than Blacks), lower counts in zip codes with higher Hispanic populations (compared to non-Hispanics), and higher prevalence among women compared to men. Furthermore, zip codes with a larger population of elderly people (age ≥ 65 years) exhibited higher LC prevalence, consistent with established national patterns. CONCLUSIONS: This comprehensive analysis contributes to our understanding of the complex interplay of demographic and socioeconomic factors influencing LC disparities in VA at the zip code level, providing valuable information for targeted public health interventions and resource allocation.
