RESUMO

The gut microbiome is a highly intricate ecosystem that exerts a pivotal influence on the host's physiology. Characterizing fish microbiomes is critical to understanding fish physiology and health, but little is known about the ecology and colonization dynamics of microorganisms inhabiting fish species. In this study, we investigated the bacterial communities of two small-bodied fish species, Cyprinella lutrensis (red shiner) and Notropis stramineus (sand shiner), two fish species where gut microbiomes have not been investigated previously and surrounding waters, collected from rivers in Nebraska, USA. Our study focused on evaluating microbial diversity in small-bodied fish and identifying autochthonous microbes present within these species irrespective of location to better understand bacterial community composition and possible roles of such bacterial species. Our results revealed that both red shiner and sand shiner exhibited gut bacterial communities dominated by typical bacterial phyla found in freshwater fish. The phylum Bacteroidota was minimally abundant in both species and significantly lower in relative abundance compared to the surrounding water microbial community. Furthermore, we found that the gut microbiomes of red shiner and sand shiner differed from the microbial community in the surrounding water, suggesting that these fish species contain host-associated bacterial species that may provide benefits to the host such as nutrient digestion and colonization resistance of environmental pathogens. The fish gut bacterial communities were sensitive to environmental conditions such as turbidity, dissolved oxygen, temperature, and total nitrogen. Our findings also show bacterial community differences between fish species; although they shared notable similarities in bacterial taxa at phyla level composition, ASV level analysis of bacterial taxa displayed compositional differences. These findings contribute to a better understanding of the gut bacterial composition of wild, freshwater, small-bodied fish and highlight the influence of intrinsic (host) and environmental factors on shaping the bacterial composition.

RESUMO

Child abuse, particularly neglect, is often preventable because many causes of harm stem from poverty, lack of social connections, substance use disorders, mental illness, lack of childcare, and other family support shortages. Prevention of child abuse and neglect starts with family support in these areas. The federal government recognized this need for prevention, and through considerable bipartisan support, passed the Family First Prevention Services Act on February 9, 2018. The Family First Prevention Services Act was designed to divert investment away from long-term foster care and toward programs that prevent unnecessary placement and child protective services interventions. The Family First Prevention Services Act restricts the state's use of federal funds for institutional foster care placements and uses those savings to fund reimbursements for evidence-based family preservation. The requirement for evidence-based prevention is a first in child-welfare federal law, and compliance with this requirement requires public-private partnership with agencies implementing the models, infrastructure, and evaluation standards that most states must build to be eligible for the new funding. This evaluation research analyzed how the stringent guidelines for prevention funding and the requirement of federally approved evidence-based practice programming affect the implementation of the Family First Prevention Services Act in Nebraska and Colorado.

RESUMO

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.

RESUMO

A male patient with distant history of extensive rabbit contact and pulmonary nodules for 6 years developed empyema. Francisella tularensis holarctica was isolated from thoracentesis fluid. Retrospective immunohistochemical examination of a pulmonary nodule, biopsied 3 years prior, was immunoreactive for F. tularensis. These findings suggest the potential for chronic tularemia.

RESUMO

Racial and ethnic minority populations experience poorer cancer outcomes compared to non-Hispanic White populations, but qualitative studies have typically focused on single subpopulations. We explored experiences, perceptions, and attitudes toward cancer care services across the care continuum from screening through treatment among African American and Hispanic residents of Nebraska to identify unique needs for education, community outreach, and quality improvement. We conducted four focus groups (N = 19), April-August 2021 with people who were aged 30 or older and who self-identified as African American or Hispanic and as cancer survivors or caregivers. Sessions followed a structured facilitation guide, were audio recorded and transcribed, and were analyzed with a directed content analysis approach. Historical, cultural, and socioeconomic factors often led to delayed cancer care, such as general disuse of healthcare until symptoms were severe due to mistrust and cost of missing work. Obstacles to care included financial barriers, transportation, lack of support groups, and language-appropriate services (for Hispanic groups). Knowledge of cancer and cancer prevention varied widely; we identified a need for better community education about cancer within the urban Hispanic community. Participants had positive experiences and a sense of hope from the cancer care team. African American and Hispanic participants shared many similar perspectives about cancer care. Our results are being used in collaboration with national and regional cancer support organizations to expand their reach in communities of color, but structural and cultural barriers still need to be addressed.

RESUMO

Despite the growing importance of community health workers (CHWs) in public health, it has been difficult to characterize the roles and scope of services for this workforce in part because of the variability in the employment status of CHWs, ranging from full-time, part-time, to volunteer. Based on analysis of survey data from a statewide assessment of the CHW workforce in Nebraska (n = 142) conducted between 2019 and 2020, the proportions of CHWs who worked full-time, part-time, or volunteer were respectively 64%, 12%, and 21%. Over three quarters (76.7%) of volunteer CHWs were primarily working with Hispanic communities, as compared to less than 30% among full-time and part-time CHWs. About 80% of volunteer CHWs received training before becoming a CHW, substantially higher than the corresponding proportions among full-time (46.2%) and part-time CHWs (52.9%). In terms of tasks performed, the proportion of volunteer CHWs who provided health screenings (70%) were much higher than full or part-time CHWs (41.8% and 11.8% respectively, p < 0.001); whereas the latter two groups were significantly more likely than volunteer CHWs to provide other tasks such as coordinating care, health coaching, social support, transportation, interpretation, data collection, advocacy, and cultural awareness. Volunteer CHWs may hold potential for serving non-Hispanic communities. Future development of the CHW workforce can benefit from understanding and leveraging the significant differences in roles and scope of services among CHWs with various employment statuses.

RESUMO

Fall-planted cover crop (CC) within a continuous corn (Zea mays L.) system offers potential agroecosystem benefits, including mitigating the impacts of increased temperature and variability in precipitation patterns. A long-term simulation using the Decision Support System for Agrotechnology Transfer model was made to assess the effects of cereal rye (Secale cereale L.) on no-till continuous corn yield and soil properties under historical (1991-2020) and projected climate (2041-2070) in eastern Nebraska. Local weather data during the historical period were used, while climate change projections were based on the Canadian Earth System Model 2 dynamically downscaled using the Canadian Centre for Climate Modelling and Analysis Regional Climate Model 4 under two representative concentration pathways (RCP), namely, RCP4.5 and RCP8.5. Simulations results indicated that CC impacts on corn yield were nonsignificant under historical and climate change conditions. Climate change created favorable conditions for CC growth, resulting in an increase in biomass. CC reduced N leaching under climate change scenarios compared to an average reduction of 60% (7 kg ha- 1 ) during the historical period. CC resulted in a 6% (27 mm) reduction in total water in soil profile (140 cm) and 22% (27 mm) reduction in plant available water compared to no cover crop during historical period. CC reduced cumulative seasonal surface runoff/soil evaporation and increased the rate of soil organic carbon buildup. This research provides valuable information on how changes in climate can impact the performance of cereal rye CC in continuous corn production and should be scaled to wider locations and CC species.

RESUMO

Because healthy psychosocial development in the first years of life is critical to lifelong well-being, governmental, and nongovernmental organizations are increasingly interested in monitoring psychosocial behaviors among populations of children. In response, the World Health Organization is developing the Global Scales of Early Development Psychosocial Form (GSED PF) to facilitate population-level psychosocial monitoring. Once validated, the GSED PF will be an open-access, caregiver-reported measure of children's psychosocial behaviors that is appropriate for infants and young children. This study examines the psychometric validity evidence from 45 items under consideration for inclusion in the GSED PF. Using data from N = 836 Nebraskan (USA) children aged 180 days to 71 months, results indicate that scores from 44 of the 45 (98%) items exhibit positive evidence of validity and reliability. A bifactor model with one general factor and five specific factors best fit the data, exhibited strong reliability, and acceptable model fit. Criterion associations with known predictors of children's psychosocial behaviors were in the expected direction. These findings suggest that measurement of children's psychosocial behaviors may be feasible, at least in the United States. Data from more culturally and linguistically diverse settings is needed to assess these items for global monitoring.


Debido a que el desarrollo sicosocial en los primeros años de vida es crítico para el bienestar de toda la vida, las organizaciones gubernamentales y no gubernamentales están más y más interesadas en observar vigilantemente las conductas sicosociales en la población infantil. Como respuesta, la Organización Mundial de la Salud está desarrollando el Formulario Sicosocial de las Escalas Globales del Temprano Desarrollo (GSED PF) para facilitar la observación sicosocial alerta al nivel del grupo de población. Una vez que se haya convalidado, el GSED PF será una medida de acceso abierto, que reportará el cuidador, sobre las conductas sicosociales de los niños que son apropiadas para infantes y niños pequeñitos. Este estudio examina la evidencia de la validez sicométrica de 45 puntos bajo consideración para ser incluidos en el GSED PF. Usando datos de N = 836 niños de Nebraska (Estados Unidos), de edad entre 180 días y 71 meses, los resultados indican que los puntajes de 44 de los 45 (98%) puntos muestran evidencia positiva de validez y confiabilidad. Un modelo bifactorial con un factor general y cinco factores específicos, que mejor encaja con los datos, mostró una fuerte confiabilidad y un modelo aceptable que encaja. Las asociaciones de criterio con factores de predicción conocidos acerca de las conductas sicosociales de los niños se encontraban en la dirección esperada. Estos resultados sugieren que la medida de las conductas sicosociales de los niños pudiera ser posible, por lo menos en los Estados Unidos. Se necesitan datos de escenarios más diversos cultural y lingüísticamente para evaluar estos puntos para la estar alerta en la observación global.

RESUMO

States all across the United States are experiencing a shortage in their behavioral health workforces. Although many studies have suggested factors that contribute to or mitigate the shortage-particularly in rural and underserved areas-no nationwide guidance exists on best practices to develop a behavioral health workforce that can meet community need. The Behavioral Health Education of Nebraska (BHECN) can serve as an exemplar for others looking to take a multifaceted approach to develop the behavioral health workforce in their community. Evidence from published studies is reviewed, and BHECN's approach and practices are explained.

RESUMO

Risk assessment of properties and associated population was conducted for the state of Nebraska, leveraging only open-source datasets. The flood risk framework consisted of interactions among drivers, i.e. hazard, exposure, vulnerability, and response, to assess the risks related to properties and associated populations. To quantify hazard on a county scale, we considered properties at risk of flooding based on a flood score (a higher score represents a greater chance of flooding). Exposure was quantified by considering population density at the county level. We quantified vulnerability under four categories: social, ecological, economic, and health. Response, a relatively newer component in flood risk assessment, was also quantified under three distinct categories: structural, non-structural, and emergency. Overall, we found that counties in eastern Nebraska (Sarpy, Dakota, Wayne, and Adams) have a higher risk of flooding consequences due to more exposure to vulnerable assets such as population and property. The assessment also observed that counties in eastern Nebraska are in the process of improving their flood control measures with dams, levees, and higher insurance coverage that can subdue the risks associated with flooding. The results from this study are anticipated to guide water managers and policymakers in making more effective and locally relevant policies and measures to mitigate flood risks and consequences.

RESUMO

Ekgmowechashala is a poorly documented but very distinctive primate known only from the late early Oligocene (early Arikareean) of western North America. Because of its highly autapomorphous dentition and spatiotemporal isolation, the phylogenetic and biogeographic affinities of Ekgmowechashala have long been debated. Here, we describe the oldest known fossils of Ekgmowechashala from the Brown Siltstone Beds of the Brule Formation, White River Group of western Nebraska. We also describe a new ekgmowechashaline taxon from the Nadu Formation (late Eocene) in the Baise Basin of Guangxi Zhuang Autonomous Region in southern China. Phylogenetic analysis suggests that North American Ekgmowechashala and the new Chinese taxon are sister taxa that are nested within a radiation of southern Asian adapiforms that also includes Gatanthropus, Muangthanhinius, and Bugtilemur. The new Chinese ekgmowechashaline helps fill the considerable disparity in dental morphology between Ekgmowechashala and more primitive ekgmowechashalids known from southern Asia. Our study underscores the fundamental role of southern Asia as a refugium for multiple primate clades during the cooler and drier climatic regime that prevailed after the Eocene-Oligocene transition. The colonization of North America by Ekgmowechashala helps define the beginning of the Arikareean Land Mammal Age and corresponds to an example of the Lazarus effect, whereby a taxon (in this case, the order Primates) reappears suddenly in the fossil record after a lengthy hiatus.

RESUMO

INTRODUCTION: Flooding represents a significant health risk to residents of states bordering the Missouri and Missis-sippi Rivers. In Nebraska and Iowa, nearly 280,000 individuals live in floodplains that put them at higher risk for expe-riencing a flood. In Nebraska, 8.60 percent of residents live within floodplains, while in Iowa, 3.83 percent of residents live in floodplains.1 Flooding poses immediate risks including injury and loss of life, but it additionally threatens long-er-term impacts due to increased exposure to environmental health risks and damage to physical and social infrastruc-ture.2,3 Health education interventions depend on risk communication based on accurate knowledge of the health beliefs of at-risk individuals. This paper outlines the development of a survey instrument designed to solicit flooding health beliefs of individuals living in river flood zones. METHODS: This study developed the survey instrument through a series of revisions designed to increase the con-struct validity of the data collected. These steps included item sourcing and modification, expert review, and cognitive interviewing. Content for the initial survey draft was sourced from existing flood risk survey instruments and other standardized demographic surveys.4-8 This study then validated the instrument through sequential expert review and cognitive interviewing, collecting and conducting qualitative analysis of data collected through each phase. RESULTS: Themes from the expert review include (1) improvement of the user experience through revision of re-sponse categories and removal of unnecessary structural elements, (2) improvement of construct representativity through attentiveness to existing flood preparedness policies in the Heartland, and (3) streamlining of data analysis through revision and clarification of item prompts and responses. Themes from the cognitive interviewing include (1) the addition of items soliciting respondents' awareness of their flood risk as well as open-ended items soliciting respond-ents' existing personal flood plan components, (2) revision of existing demographic items to solicit respondents' esti-mated-rather than exact-household income, and (3) clarification of our definition of a flooding event. DISCUSSION: This study adapted existing survey items into an instrument designed to gather data on respondents' flood health beliefs and relevant demographic characteristics, producing a developed instrument that can be used to measure a population's flood health beliefs with reasonable evidence of validity. This instrument may be further tested by gathering baseline data and conducting psychometric testing to determine which items wield significant influence over respondents' decision to develop a personal or household flood plan.9 Additionally, this study provides a model for risk communication professionals seeking to adapt existing survey items to develop instruments designed to gather data on locally relevant health outcomes.10.

RESUMO

Soybean gall midge, Resseliella maxima Gagné, was recently identified as a new species causing significant injury to soybean and is currently found in 164 counties across 7 midwestern states (NE, IA, SD, MN, MO, ND, and KS). Infestation of soybean begins in late spring, when adults emerge from last year's soybean field. Infestation of a new soybean crop depends on the presence of fissures which start to form at the base of the soybean plant around the V2 stage. Field observations indicate that these fissures are only present below the cotyledonary nodes or in the area within 3-5 cm above the soil surface. To determine the importance of these fissures for R. maxima infestation and plant injury, hilling or the movement of the soil to cover the base of soybean plants at the V2-V3 stage was compared with the standard practice (no-hilling). Field studies were conducted at 3 sites in east-central Nebraska during the 2021 growing season. The results showed a significant reduction in the frequency of infested plants, larval number per plant, and plant injury for hilled compared to no-hill treatment. This reduction in the presence of larvae and plant injury corresponded with a significantly greater yield for hilled compared to the no-hill treatment. These results highlight the importance of fissures on soybean for R. maxima adult infestation as well as the potential for hilling to be used as a management strategy for R. maxima.

RESUMO

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.

RESUMO

Species of different sizes interact with the landscape differently because ecological structure varies with scale, as do species movement capabilities and habitat requirements. As such, landscape connectivity is dependent upon the scale at which an animal interacts with its environment. Analyses of landscape connectivity must incorporate ecologically relevant scales to address scale-specific differences. Many evaluations of landscape connectivity utilize incrementally increasing buffer distances or other arbitrary spatial delineations as scales of analysis. Instead, we used a mammalian body mass discontinuity analysis to objectively identify scales in the Central Platte River Valley (CPRV) of Nebraska, U.S.A. We implemented a graph-theoretic network analysis to evaluate the connectivity of two wetland land cover types in the CPRV, wet meadow and emergent marsh, at multiple scales represented by groupings of species with similar body mass. Body mass is allometric with multiple traits of species, including dispersal distances. The landscape was highly connected at larger scales but relatively unconnected at smaller scales. We identified a threshold at which the landscape becomes highly connected between 500 m and 6,500 m dispersal distances. The presence of a connectivity threshold suggests that species with dispersal distances close to the threshold may be most vulnerable to habitat loss or reconfiguration and management should account for the connectivity threshold. Furthermore, we propose that a multiscale approach to management will be necessary to ensure landscape connectivity for diverse species.

RESUMO

Primary amebic meningoencephalitis (PAM) is a rare and lethal infection caused by Naegleria fowleri. We report an epidemiological and environmental investigation relating to a case of PAM in a previously healthy boy age 8 years. An interview of the patient's family was conducted to determine the likely exposure site and to assess risk factors. Data from the United States Geological Survey site at Waterloo, NE, on the Elkhorn River were used to estimate water temperature and streamflow at the time and site of exposure. Data from the National Weather Service were used to estimate precipitation and ambient air temperature at the time and site of exposure. Despite conventional treatment, the patient died 2 days after hospital admission. The patient participated in recreational water activities in the Elkhorn River in northeastern Nebraska 5 days before symptom onset. In the week before exposure, water and ambient air high temperatures reached annual highs, averaging 32.4°C and 35.8°C, respectively. The day before infection, 2.2 cm of precipitation was reported. Streamflow was low (407 ft3/s). Infections in several northern states, including Nebraska, suggest an expanding geographic range of N. fowleri transmission, which may lead to increased incidence of PAM in the United States. Similar environmental investigations at suspected exposure sites of future cases will allow data aggregation, enabling investigators to correlate environmental factors with infection risk accurately.

RESUMO

Nationally and in Nebraska, African Americans (AA) and Hispanics have lower colorectal cancer (CRC) screening rates compared to non-Hispanic Whites. We aimed to obtain perspectives from AA and Hispanic cancer survivors and caregivers in Nebraska about CRC screening to improve outreach efforts. Data from four virtual focus groups (AA female, AA male, Hispanic rural, and Hispanic urban) conducted between April-August 2021 were analyzed using a directed content approach based on the Predisposing, Reinforcing, and Enabling Constructs in Educational Diagnosis and Evaluation (PRECEDE) model. Most of the 19 participants were female (84%) and survivors (58%). Across groups, awareness of colonoscopy was high, but awareness of fecal testing needed to be higher, with confusion about different types of fecal tests. Predisposing factors were trust in the health system; awareness of CRC screening; machismo; fear of cancer; embarrassment with screening methods; and negative perceptions of CRC screening. Enabling factors included provider recommendations, healthcare access, and insurance. Reinforcing factors included prioritizing personal health and having a support system. Suggestions to improve screening included increasing healthcare access (free or low-cost care), increasing provider diversity, health education using various methods and media, and enhancing grassroots health promotion efforts. Lack of awareness, accessibility issues, attitudes and perceptions of CRC and CRC screening, trust, and cultural and linguistic concerns are major issues that need to be addressed to reduce CRC screening disparities among AA and Hispanic adults.

RESUMO

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.

RESUMO

INTRODUCTION: Rollover protective structures (ROPS) can prevent fatal tractor overturns, a leading cause of death among farmers. This content analysis aims to understand how this life-saving strategy appears in news about farm safety. METHODS: As part of a larger study of farm safety news coverage from four agricultural states, we conducted a content analysis of articles that mentioned ROPS. RESULTS: Few (10%) articles about farm safety explicitly mentioned ROPS. When ROPS were mentioned, they were described in terms of their potential to save lives or prevent injury. CONCLUSION: Despite proven success, ROPS-and programs to make ROPS more widely available to farmers-are all but absent from news coverage in key agricultural states. This represents a missed opportunity not only to motivate farmers to install ROPS, but also to demonstrate to policymakers the importance of establishing and maintaining funding to prevent the most frequent cause of death on farms. Farmers face barriers to installing life-saving equipment. Without an increase in ROPS utilization and improved access to prevention programs, farmers, especially low-income farmers, will remain at disproportionate risk for death and injury.
