Engaging Communities in Cancer Prevention and Control Activity Prioritization through a Statewide Needs Assessment: A Case Study from Nebraska.

Community outreach and engagement (COE) activities are important in identifying catchment area needs, communicating these needs, and facilitating activities relevant to the population. The National Cancer Institute-designated cancer centers are required to conduct catchment-wide cancer needs assessments as part of their COE activities. The University of Nebraska Medical Center Buffett Cancer Center undertook a three-year-long process to conduct a needs assessment, identify priorities, and develop workgroups to implement cancer prevention and control activities. Activities were conducted through collaborations with internal and external partners. The needs assessment focused on prevention, early detection, and treatment of cancer and involved secondary data analysis and focus groups with identified underrepresented priority populations (rural, African American, Hispanic, Native American, and LGBTQ+ populations). Results were tailored and disseminated to specific audiences via internal and external reports, infographics, and presentations. Several workgroups were developed through meetings with the internal and external partners to address identified priorities. COE-specific initiatives and metrics have been incorporated into University of Nebraska Medical Center and Buffett Cancer Center strategic plans. True community engagement takes a focused effort and significant resources. A systemic and long-term approach is needed to develop trusted relationships between the COE team and its local communities.

DETECTION OF SARS-COV-2 NEUTRALIZING ANTIBODIES IN RETROPHARYNGEAL LYMPH NODE EXUDATES OF WHITE-TAILED DEER (ODOCOILEUS VIRGINIANUS) FROM NEBRASKA, USA.

Disease surveillance testing for emerging zoonotic pathogens in wildlife is a key component in understanding the epidemiology of these agents and potential risk to human populations. Recent emergence of SARS-CoV-2 in humans, and subsequent detection of this virus in wildlife, highlights the need for developing new One Health surveillance strategies. We used lymph node exudate, a sample type that is routinely collected in hunter-harvested white-tailed deer (WTD, Odocoileus virginianus) for surveillance of chronic wasting disease, to assess anti-SARS-CoV-2 neutralizing antibodies. A total of 132 pairs of retropharyngeal lymph nodes collected from Nebraska WTD harvested in Nebraska, US, in 2019 (pre-SARS-CoV-2 pandemic) and 2021 (post-SARS-CoV-2 pandemic) were tested for SARS-CoV-2 with reverse transcription PCR. Thereafter, exudates obtained from these same lymph nodes were tested for SARS-CoV-2 neutralizing antibodies using a surrogate virus neutralization test. Neutralizing antibodies were detected in the exudates with high diagnostic specificity (100% at proposed cutoff of 40% inhibition). Application of this testing approach to samples collected for use in other disease surveillance activities may provide additional epidemiological data on SARS-CoV-2 exposure, and there is further potential to apply this sample type to detection of other pathogens of interest.

A Public Health Laboratory Information System in Support of Health Emergencies: The Nebraska Public Health Laboratory COVID-19 Experience.

OBJECTIVES: Public health laboratories (PHLs) are essential components of US Public Health Service operations. The health information technology that supports PHLs is central to effective and efficient laboratory operations and overall public health response to infectious disease management. This analysis presents key information on how the Nebraska Public Health Laboratory (NPHL) information technology system evolved to meet the demands of the COVID-19 pandemic. MATERIALS AND METHODS: COVID-19 presented numerous, unforeseen information technology system challenges. The most notable challenges requiring changes to NPHL software systems and capability were improving efficiency of the laboratory operation due to high-volume testing, responding daily to demands for timely data for analysis by partner systems, interfacing with multiple testing (equipment) platforms, and supporting community-based specimen collection programs. RESULTS: Improvements to the NPHL information technology system enabled NPHL to perform >121 000 SARS-CoV-2 polymerase chain reaction tests from March 2020 through January 2022 at a sustainable rate of 2000 SARS-CoV-2 tests per day, with no increase in laboratory staffing. Electronic reporting of 62 000 rapid antigen tests eliminated paper reporting and extended testing services throughout the state. Collection of COVID-19 symptom data before specimen collection enabled NPHL to make data-driven decisions to perform pool testing and conserve testing kits when supplies were low. PRACTICE IMPLICATIONS: NPHL information technology applications proved essential for managing health care provider workload, prioritizing the use of scarce testing supplies, and managing Nebraska's overall pandemic response. The NPHL experience provides useful examples of a highly capable information technology system and suggests areas for additional attention in the PHL environment, including a focus on end users, collaboration with various partners, and investment in information technology.

Detection of Borrelia burgdorferi infected Ixodes scapularis (Acari: Ixodidae) associated with local Lyme disease transmission in Nebraska, USA, 2021.

In August 2021, the Nebraska Department of Health and Human Services was notified by a local public health department of a cluster of two Lyme disease cases in patients with local exposure to wooded areas in a county located in their jurisdiction. Epidemiological investigations revealed that the two patients had similar symptom onset dates and had likely exposure to ticks at wooded sites located directly adjacent to one another. Two environmental investigations were completed in October 2021 and consisted of tick surveys at the patients' reported sites of tick exposure. 12 ticks were collected across the two surveys and identified the black-legged tick (Ixodes scapularis). During subsequent testing of the collected ticks, spirochete bacteria were isolated, cultured and confirmed as Borrelia burgdorferi sensu stricto by PCR. In total, 7 of 12 (58.3%) I. scapularis ticks tested positive for B. burgdorferi s.s. The results of this study document the fourth known established population of I. scapularis in Nebraska and confirms the first detection of B. burgdorferi s.s. in field collected ticks from Nebraska. The epidemiological and environmental investigation data provide the first evidence for local Lyme disease transmission occurring within Nebraska. These findings highlight the need for continued surveillance of I. scapularis and its associated pathogens in Nebraska to further characterize human risk and monitor emergence into other areas of the state.

Factors associated with delaying medical care: cross-sectional study of Nebraska adults.

BACKGROUND: Delayed medical care may result in adverse health outcomes and increased cost. Our purpose was to identify factors associated with delayed medical care in a primarily rural state. METHODS: Using a stratified random sample of 5,300 Nebraska households, we conducted a cross-sectional mailed survey with online response option (27 October 2020 to 8 March 2021) in English and Spanish. Multiple logistic regression models calculated adjusted odds ratios (aOR) and 95% confidence intervals. RESULTS: The overall response rate was 20.8% (n = 1,101). Approximately 37.8% of Nebraskans ever delayed healthcare (cost-related 29.7%, transportation-related 3.7%), with 22.7% delaying care in the past year (10.1% cost-related). Cost-related ever delay was associated with younger age [< 45 years aOR 6.17 (3.24-11.76); 45-64 years aOR 2.36 (1.29-4.32)], low- and middle-income [< $50,000 aOR 2.85 (1.32-6.11); $50,000-$74,999 aOR 3.06 (1.50-6.23)], and no health insurance [aOR 3.56 (1.21-10.49)]. Transportation delays were associated with being non-White [aOR 8.07 (1.54-42.20)], no bachelor's degree [≤ high school aOR 3.06 (1.02-9.18); some college aOR 4.16 (1.32-13.12)], and income < $50,000 [aOR 8.44 (2.18-32.63)]. Those who did not have a primary care provider were 80% less likely to have transportation delays [aOR 0.20 (0.05-0.80)]. CONCLUSIONS: Delayed care affects more than one-third of Nebraskans, primarily due to financial concerns, and impacting low- and middle-income families. Transportation-related delays are associated with more indicators of low socio-economic status. Policies targeting minorities and those with low- and middle-income, such as Medicaid expansion, would contribute to addressing disparities resulting from delayed care.

Predictors of cancer risky and preventive behaviors among the Nebraska farmers population.

PURPOSE: Previous studies on cancer risk among agricultural producers have focused on occupational exposures, with only a few studies examining behavioral factors. The aim of this study was to understand cancer risky and preventative behaviors among the large farming population in Nebraska. METHODS: A statewide cross-sectional study of farmers in Nebraska aged 19 and older was conducted in 2019 (n = 782). Multivariable logistic regression was used to examine factors associated with being up to date on cancer screening and with cancer risky and preventive behaviors. FINDINGS: The 93.68% of the Nebraska farmers population do not meet the daily recommended consumption of fruits and vegetables, and 70.14% reported regular alcohol consumption. The proportion of adults up to date on cancer screening was 79.57% for breast, 67.55% for cervical, 85.54% for colorectal, and 46.05% for skin cancers. Compared to women, men had a higher odds of heavy alcohol consumption (aOR 2.96, 95% CI 1.94-4.56) and ever smoking 100 or more cigarettes (aOR 1.66, 95% CI 1.03-2.73). The odds of being current with skin cancer screening was higher among those with higher incomes (aOR 1.77, 95% CI 1.06-3.01). Compared to men aged 50-64, the odds of being current with prostate cancer screening was higher among men aged 65-74 (aOR: 2.65, 95% CI 1.10-7.31) and 75 and older (aOR: 7.73, 95% CI 2.03-51.73). CONCLUSIONS: Disparities in cancer screening and risk and preventive behaviors exist among farmers in Nebraska. The study highlights a need for continuing efforts to improve preventive cancer behaviors targeted to the farming population.

Information Sources and Attitudes Toward COVID-19 Vaccination at a Free Clinic in the State of Nebraska, USA.

The full impacts of the COVID-19 pandemic are yet to be determined. While highly effective vaccines are available to prevent and decrease the severity of COVID-19 infection, significant COVID-19 vaccine hesitancy remains. Understanding motivations, discouraging factors, opinions, and information sources regarding COVID-19 is essential to targeting vaccine hesitancy and improving vaccine uptake. A 25 question survey was administered to the patients of a free clinic in the Midwest to assess patient demographic data, opinions about and experience with COVID-19, the COVID-19 vaccines, and information sources. The main outcome of interest was if vaccination status influenced information sources and opinions regarding COVID-19. This study also analyzed motivating and discouraging factors for vaccination. The study had a total of 104 participants with 7 being excluded. There were a total of 97 survey responses included in this study, there were 79 vaccinated patients and 18 unvaccinated patients. This survey study found differences in information sources between vaccinated and unvaccinated groups. Opinions surrounding the COVID-19 vaccine, public health agencies, and perceived severity of COVID-19 also varied between vaccinated and unvaccinated groups. The differential information sources and opinions between vaccinated and unvaccinated groups emphasizes the importance of access to high-quality sources and educating the community to improve public health.

Type 1 Diabetes Management and Health Care Experiences Across Rural Nebraska.

INTRODUCTION: This study aimed to explore the unique health care needs of rural Nebraska families with a child with type 1 diabetes mellitus (T1DM). METHOD: Using a phenomenological approach, the researchers conducted four focus groups across Nebraska. The focus groups gathered input from children, caregivers, and health care providers (n = 23). The researchers coded data and generated themes. Member checking, researcher triangulation, reflexivity, a thick description of the process, and an audit trail established trustworthiness. RESULTS: Four themes emerged: dramatic family and lifestyle changes following diagnosis, lack of access to specialized care resulting in complications, isolation improved health management resourcefulness, and technology improved health management and flexibility. DISCUSSION: Lifestyle changes persist after a child's diagnosis with T1DM. Rural families reported unpredictable health status of their child, reduced health care services, and limited information access. Conversely, limited specialty health care access, resources, and community support led to creative self-education, advocacy, and health care management strategies. Diabetes technology offered opportunities for improved provider-patient communication and continuous glucose monitoring.

Outbreak of SARS-CoV-2 B.1.617.2 (Delta Variant) in a Youth Camp Associated With Community Spread, Nebraska, June-July 2021.

OBJECTIVES: During June-July 2021, an outbreak of SARS-CoV-2 occurred among attendees of a summer youth camp in Nebraska. We assessed the factors that contributed to onward transmission of disease. METHODS: The Four Corners Health Department conducted an outbreak investigation and recorded both laboratory-confirmed and self-reported cases of SARS-CoV-2 and mitigation measures employed. We generated sequences on positive specimens, created an epidemic curve to assist with outbreak visualization, and examined epidemiologic, genomic, and laboratory outcomes. RESULTS: Evaluation of 3 index cases led to the identification of 25 people with COVID-19 who interacted directly with the camp. Contact tracing revealed an additional 18 cases consistent with onward community transmission. Most (24 of 35, 68.5%) vaccine-eligible community cases were not vaccinated. We sequenced 8 positive specimens; all were identified as the Delta variant. Precamp planning incorporated local health officials who recommended wearing face masks, practicing social distancing, and using attendee cohorts to limit mixing of people involved in various activities. CONCLUSION: Low vaccination levels and poor face mask-wearing habits among attendees resulted in secondary and tertiary spread of SARS-CoV-2 and severe outcomes among young adults. This outbreak of COVID-19 at a youth camp highlights the importance of vaccination and use of other measures to interrupt opportunities for SARS-CoV-2 spread in the community and shows that vaccinated people remain vulnerable to infection when in an environment of high exposure to SARS-CoV-2. Proactive case identification and interruption of chains of transmission can help decrease the number of cases and avoid further severe outcomes.

Access, socioeconomic environment, and death from COVID-19 in Nebraska.

Our study assesses whether factors related to healthcare access in the first year of the pandemic affect mortality and length of stay (LOS). Our cohort study examined hospitalized patients at Nebraska Medicine between April and October 2020 who were tested for SARS-CoV-2 and had a charted sepsis related diagnostic code. Multivariate logistic was used to analyze the odds of mortality and linear regression was used to calculate the parameter estimates of LOS associated with COVID-19 status, age, gender, race/ethnicity, median household income, admission month, and residential distance from definitive care. Among 475 admissions, the odds of mortality is greater among those with older age (OR: 1.04, 95% CI: 1.02-1.07) and residence in an area with low median household income (OR: 2.11, 95% CI: 0.52-8.57), however, the relationship between mortality and wealth was not statistically significant. Those with non-COVID-19 sepsis had longer LOS (Parameter Estimate: -5.11, adjusted 95% CI: -7.92 to -2.30). Distance from definitive care had trends toward worse outcomes (Parameter Estimate: 0.164, adjusted 95% CI: -1.39 to 1.97). Physical and social aspects of access to care are linked to poorer COVID-19 outcomes. Non-COVID-19 healthcare outcomes may be negatively impacted in the pandemic. Strategies to advance patient-centered outcomes in vulnerable populations should account for varied aspects (socioeconomic, residential setting, rural populations, racial, and ethnic factors). Indirect impacts of the pandemic on non-COVID-19 health outcomes require further study.

Examining missingness among children in out-of-home care placement in Nebraska.

BACKGROUND: Little is known regarding the prevalence and context of missingness (i.e., being reported as a missing person) among children in out-of-home (OOH) care. OBJECTIVE: The present research examines the relationship between missingness and OOH care placements as well as predictors and case contexts of children missing from OOH care. METHODS: Point-in-time count data of reported missing persons in Nebraska and administrative records on children's OOH placements are used. Bivariate significance tests examine group differences; case contexts are explored through content analysis of OOH case reviews. RESULTS: About 30 % of Nebraska's missing children are in OOH care. Bivariate tests show that children missing from OOH care are older and are more likely to be Black and less likely to have their race listed as "unknown" than children missing from their families of origin. Children in OOH who are missing are also more likely to be in group care, on probation, and have greater placement instability compared to children in OOH care who are not missing. Case contexts of missingness include unmet substance use and mental health challenges, experiences with violence and victimization, and few bonds to school. CONCLUSIONS: Screening and interventions for high-need children in OOH care and their caregivers are necessary to prevent children from going missing from placements.

Origins of high latitude introductions of Aedes aegypti to Nebraska and Utah during 2019.

Aedes aegypti (L.), the yellow fever mosquito, is also an important vector of dengue and Zika viruses, and an invasive species in North America. Aedes aegypti inhabits tropical and sub-tropical areas of the world and in North America is primarily distributed throughout the southern US states and Mexico. The northern range of Ae. aegypti is limited by cold winter months and establishment in these areas has been mostly unsuccessful. However, frequent introductions of Ae. aegypti to temperate, non-endemic areas during the warmer months can lead to seasonal activity and disease outbreaks. Two Ae. aegypti incursions were reported in the late summer of 2019 into York, Nebraska and Moab, Utah. These states had no history of established populations of this mosquito and no evidence of previous seasonal activity. We genotyped a subset of individuals from each location at 12 microsatellite loci and ~ 14,000 single nucleotide polymorphic markers to determine their genetic affinities to other populations worldwide and investigate their potential source of introduction. Our results support a single origin for each of the introductions from different sources. Aedes aegypti from Utah likely derived from Tucson, Arizona, or a nearby location. Nebraska specimen results were not as conclusive, but point to an origin from southcentral or southeastern US. In addition to an effective, efficient, and sustainable control of invasive mosquitoes, such as Ae. aegypti, identifying the potential routes of introduction will be key to prevent future incursions and assess their potential health threat based on the ability of the source population to transmit a particular virus and its insecticide resistance profile, which may complicate vector control.

Drought and all-cause mortality in Nebraska from 1980 to 2014: Time-series analyses by age, sex, race, urbanicity and drought severity.

BACKGROUND: Climate change will increase drought duration and severity in many regions around the world, including the Central Plains of North America. However, studies on drought-related health impacts are still sparse. This study aims to explore the potential associations between drought and all-cause mortality in Nebraska from 1980 to 2014. METHODS: The Evaporative Demand Drought Index (EDDI) were used to define short-, medium- and long-term drought exposures, respectively. We used a Bayesian zero-inflated censored negative binomial (ZICNB) regression model to estimate the overall association between drought and annual mortality first in the total population and second in stratified sub-populations based on age, race, sex, and the urbanicity class of the counties. RESULTS: The main findings indicate that there is a slightly negative association between all-cause mortality and all types of droughts in the total population, though the effect is statistically null. The joint-stratified analysis renders significant results for a few sub-groups. White population aged 25-34 and 45-64 in metro counties and 45-54 in non-metro counties were the population more at risk in Nebraska. No positive associations were observed in any race besides white. Black males aged 20-24 and white females older than 85 showed protective effect against drought mainly in metro counties. We also found that more sub-populations had higher rates of mortality with longer-term droughts compared to shorter-term droughts (12-month vs 1- or 6-month timescales), in both metro and non-metro counties, collectively. CONCLUSION: Our results suggest that mortality in middle aged white population in Nebraska shows a greater association with drought. Moreover, women aged 45-54 were more affected than men in non-metro counties. With a projected increase in the frequency and severity of drought due to climate change, understanding these relationships between drought and human health will better inform drought mitigation planning to reduce potential impacts.

Correlates of Betel Nut Chewing among Burmese Refugees in Nebraska.

BACKGROUND: Betel nut chewing is an important risk factor for oral cancer, yet there has been little research identifying correlates of betel nut chewing among Burmese refugees in the U.S. METHODS: Based on survey data from 188 Burmese refugees from Nebraska between 2015 and 2016, logistic regression was estimated to identify correlates of betel nut chewing. RESULTS: The prevalence rate of betel nut chewing among participating Burmese refugees in Nebraska was 29%. Relative to Burmese refugees who had an education of less than high school, refugees with higher education were less likely to report betel nut chewing (AOR=0.1, 95% CI (0.02, 0.61)). Refugees who worked full time had higher odds of chewing betel nuts compared to those otherwise (AOR=6.17, 95% CI (1.80, 21.10)). Delaying medication purchase due to cost during the past 12 months was associated with higher odds of betel nut chewing (AOR=5.20, 95% CI (1.02, 26.39)). CONCLUSIONS: Betel nut chewing was common among Burmese refugees in the U.S., yet the odds of betel nut chewing varied across different socioeconomic groups. Health education programs that aim to reduce betel nut chewing might become more cost-effective by disproportionately targeting and serving high-risk groups among Burmese refugees.

Co-use among confidants: An examination of polysubstance use and personal relationships in southeastern Nebraska.

This study examines the relationship between personal networks and polysubstance use among people who use drugs (PWUD) in a medium sized city in the Midwest. A large body of work has demonstrated that personal relationships have an ambivalent association with substance use. On the one hand, a supportive network is associated with safer drug use practices and dramatically improves the outlook for recovery. However, individuals whose personal networks are composed of co-drug use partners are more likely to engage in risky practices. We argue that this notion of "supportive" social contacts and "risky" social contacts is ultimately incomplete: risky behaviors are introduced and further developed in a social context, often with the people who provide emotional support. We argue that personal networks with more multiplex relationships (where co-drug use and confiding fuse) are harmful because they combine norms of trust and reciprocity with drug use. We use data from the Rural Health Cohort (RHC) study to test this idea. The sample consists of 120 adult PWUD in a medium sized city located in southeastern Nebraska who were recruited using respondent-driven sampling. Participants listed up to nine confidants and nine co-drug use partners, indicating any overlap between the two networks. Our results demonstrate that multiplex ties are as strongly associated with polysubstance use as simple co-drug use relationships. As the drug crisis has increasingly shifted to underserved populations outside large urban centers, this paper represents an important advance in our understanding of the current drug crisis.

Low-Level Groundwater Atrazine in High Atrazine Usage Nebraska Counties: Likely Effects of Excessive Groundwater Abstraction.

Recent studies observed a correlation between estrogen-related cancers and groundwater atrazine in eastern Nebraska counties. However, the mechanisms of human exposure to atrazine are unclear because low groundwater atrazine concentration was observed in counties with high cancer incidence despite having the highest atrazine usage. We studied groundwater atrazine fate in high atrazine usage Nebraska counties. Data were collected from Quality Assessed Agrichemical Contaminant Nebraska Groundwater, Parameter-Elevation Regressions on Independent Slopes Model (PRISM), and water use databases. Descriptive statistics and cluster analysis were performed. Domestic wells (59%) were the predominant well type. Groundwater atrazine was affected by well depth. Clusters consisting of wells with low atrazine were characterized by excessive groundwater abstraction, reduced precipitation, high population, discharge areas, and metropolitan counties. Hence, low groundwater atrazine may be due to excessive groundwater abstraction accompanied by atrazine. Human exposure to atrazine in abstracted groundwater may be higher than the estimated amount in groundwater.

Investigation of a SARS-CoV-2 B.1.1.529 (Omicron) Variant Cluster - Nebraska, November-December 2021.

The B.1.1.529 (Omicron) variant of SARS-CoV-2 (the virus that causes COVID-19) was first detected in specimens collected on November 11, 2021, in Botswana and on November 14 in South Africa;* the first confirmed case of Omicron in the United States was identified in California on December 1, 2021 (1). On November 29, the Nebraska Department of Health and Human Services was notified of six probable cases† of COVID-19 in one household, including one case in a man aged 48 years (the index patient) who had recently returned from Nigeria. Given the patient's travel history, Omicron infection was suspected. Specimens from all six persons in the household tested positive for SARS-CoV-2 by reverse transcription-polymerase chain reaction (RT-PCR) testing on December 1, and the following day genomic sequencing by the Nebraska Public Health Laboratory identified an identical Omicron genotype from each specimen (Figure). Phylogenetic analysis was conducted to determine if this cluster represented an independent introduction of Omicron into the United States, and a detailed epidemiologic investigation was conducted. This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.§.

Telehealth genetic services during the COVID-19 Pandemic: Implementation and patient experiences across multiple specialties in Nebraska.

The COVID-19 pandemic has altered the delivery of genetics services. In response to the pandemic, our genetics department offered telehealth visits to all outpatients, regardless of their physical proximity to Omaha, Nebraska. Traditionally, our department did not offer telehealth visits to patient's homes or to patients who lived in close proximity to a genetics clinic. Therefore, we designed a survey to gain insight into the patient experience with remote genetic counseling appointments during the pandemic. Any patient referred to see a genetics provider in pediatrics, prenatal, adult, or cancer between March 16, 2020 and October 28, 2020 was eligible for the study. The survey included both quantitative and qualitative measures to assess patient demographics, patient experience, stressors during the COVID-19 pandemic, and anxiety and depression. We hypothesized that patients would report they received quality care by telehealth despite the presence of COVID-19-related stressors or anxiety/depression. From the 143 survey participants, 80% had their first telehealth appointment during the pandemic. The vast majority (96%) reported that they felt like they received quality care by telehealth. Additionally, more than 93% of participants strongly or somewhat agreed that their genetic providers were attentive to their emotional needs, medical needs, and privacy. Since March 2020, participants reported experiencing several COVID-19-related stressors including fear of illness (86%), feelings of isolation (45%), and safety concerns (33%). Relatively low levels of depressive and anxiety symptoms were recorded using the HADS questionnaire. Despite the prevalence of COVID-19 stressors, depression, and/or anxiety, our participants felt they received quality care via telehealth. In fact, 51% agree that they prefer to receive future genetics services virtually. These results suggest the value of telehealth as an alternative service delivery model, even for local patients, and should be offered for future appointments, beyond the COVID-19 pandemic.
