Massive Bezoar in a Free-Ranging South African Oryx (Oryx gazella gazella) in South-Central New Mexico, USA

We documented a 23 kg bezoar that filled >60% of the rumen of an adult oryx (Oryx gazella gazella) harvested in New Mexico, US. The nidus of the bezoar was comprised of nylon cords and parachute cloth, constituents of parachutes. Although slightly thin, the oryx was otherwise healthy at harvest.

The shale gas production and economic growth in local economies across the US

Recently, several seminal works have been drawing attention to the revolution of shale gas production technology of the USA, the impact of shale gas on energy sectors, as well as the influences of shale gas on macroeconomic variables of employment, economic growth, etc. Nevertheless, one may claim that two gaps appear in literature. The first gap is the absence of an econometric study estimating the effect of shale oil/gas on national economies. The more considerable second gap is the absence of econometric analyses revealing the impulses of shale gas on local economies. Therefore, this paper observes the possible causalities between the shale gas and local gross domestic product (GDP) employing quarterly data covering the period 2007-2016 for 12 states in the US. After performing the tests of cross-sectional dependence, heterogeneity, stationarity, and cointegration, the paper conducts the panel Granger causality analyses. The empirical findings depict that (i) there is available unidirectional relationship from local shale gas production to local GDP in Colorado, Ohio, and West Virginia; (ii) there occurs an impulse from GDP to local shale gas production for Louisiana, North Dakota, and Oklahoma; (iii) a bidirectional causality coexists between local shale gas production and GDP in Arkansas, California, and Texas; and (iv) there exists no association between local GDP and local shale gas extraction in Montana, New Mexico, and Wyoming.

New Dromaeosaurid Dinosaur (Theropoda, Dromaeosauridae) from New Mexico and Biodiversity of Dromaeosaurids at the end of the Cretaceous

Dromaeosaurids (Theropoda: Dromaeosauridae), a group of dynamic, swift predators, have a sparse fossil record, particularly at the time of their extinction near the Cretaceous-Paleogene boundary. Here we report on a new dromaeosaurid, Dineobellator notohesperus, gen. and sp. nov., consisting of a partial skeleton from the Upper Cretaceous (Maastrichtian) of New Mexico, the first diagnostic dromaeosaurid to be recovered from the latest Cretaceous of the southern United States (southern Laramidia). The holotype includes elements of the skull, axial, and appendicular skeleton. The specimen reveals a host of morphologies that shed light on new behavioral attributes for these feathered dinosaurs. Unique features on its forelimbs suggest greater strength capabilities in flexion than the normal dromaeosaurid condition, in conjunction with a relatively tighter grip strength in the manual claws. Aspects of the caudal vertebrae suggest greater movement near the tail base, aiding in agility and predation. Phylogenetic analysis places Dineobellator within Velociraptorinae. Its phylogenetic position, along with that of other Maastrichtian taxa (Acheroraptor and Dakotaraptor), suggests dromaeosaurids were still diversifying at the end of the Cretaceous. Furthermore, its recovery as a second North American Maastrichtian velociraptorine suggests vicariance of North American velociraptorines after a dispersal event during the Campanian-Maastrichtian from Asia. Features of Dineobellator also imply that dromaeosaurids were active predators that occupied discrete ecological niches while living in the shadow of Tyrannosaurus rex, until the end of the dinosaurs' reign.

International Public Health Laboratory Twinning: An Innovative Approach to Strengthen the National Health Laboratory System in Uganda, 2014-2017

International initiatives to strengthen national health laboratory systems in resource-poor countries are often hampered by unfamiliarity with the country's health laboratory environment and turnover of international partners during the initiative. This study provides an overview of, and lessons learned from, the use of a laboratory long-term partnership approach (ie, "twinning") to strengthen the national public health laboratory system in an international setting. We focused on the partnering of the Uganda Ministry of Health Central Public Health Laboratory (CPHL) with the New Mexico State Public Health Laboratory to help the CPHL become Uganda's national public health reference laboratory (Uganda National Health Laboratory Services [UNHLS] Institute) and leader of its nascent Uganda National Health Laboratory Network (UNHLN). Via twinning, CPHL leadership received training on laboratory leadership and management, quality systems, facility management, and the One Health environmental strategy (ie, that the health of persons is connected to the health of animals and the environment), and drafted a National Health Laboratory Policy, UNHLS Institute business plan, and strategic and operating plans for the UNHLS Institute and UNHLN. The CPHL is now responsible for the UNHLS Institute and coordinates the UNHLN. Lessons learned include (1) twinning establishes stable long-term collaborations and (2) success requires commitment to a formal statement of activities and objectives, as well as clear and regular communication among partners.

Community-clinic linkages: qualitative provider perspectives on partnering with community health representatives in Navajo Nation

OBJECTIVE

To understand providers' opinions about the Community Outreach and Patient Empowerment (COPE) Project designed to strengthen Navajo Community Health Representative (CHR) outreach to individuals living with diabetes.

DESIGN

This was a qualitative study nested within a larger evaluation of a programme intervention.

SETTING

The study took place in Navajo Nation and evaluated a programme initiative designed to strengthen collaboration between CHRs and clinic-based healthcare providers and provide structured outreach to individuals living with diabetes in Navajo Nation. The CHR Programme is a formal community health worker programme that exists in most tribal healthcare systems across the USA.

PARTICIPANTS

Healthcare providers involved in the programme took part in one-on-one interviews.

ANALYSIS

We used thematic analysis for this study. A team of three study staff used open-coding to create a codebook. Coded material were summarised and patterns were identified and tied into a narrative using concept mapping. The study design and instrument construction were guided by a Community Health Advisory Panel.

RESULTS

A total of 13 interviews were completed. Providers acknowledged CHRs as an asset to the clinical team and were enthusiastic about the COPE coaching materials, mentioning they provided a consistent message to CHRs and the community. Providers that led COPE trainings with CHRs valued the face-to-face time and opportunity to build relationships. Providers (n=4) supported CHRs' access to electronic health record to record patient visits and streamline referrals. Among their requests were having designated personnel to manage referrals with CHRs and a formal system to record modules CHRs have completed.

CONCLUSION

Providers participating in COPE activities valued the work of CHRs and endorsed further strengthening relationships and communication with CHRs. Healthcare programmes should consider systems changes to integrate community health workers into clinic-based teams.

The Role of Substance Use and Resiliency Factors on Suicidal Ideation among Middle School Students

BACKGROUND

Suicidal ideation, an important risk factor for suicide, is strongly associated with substance use. Factors such as family cohesion, connection with friends, and social support can be protective against suicidal behaviors. The purpose of this study was to explore the association between suicidal ideation, substance use, and resiliency factors among middle school students.

METHODS

The 2013 New Mexico Youth Risk and Resiliency Survey provided the data for this analysis. Suicidal ideation was defined as affirmative responses to questions about thoughts of killing oneself and/or making a suicide plan. We used logistic regression to explore the association between suicidal ideation, substance use, and resiliency factors.

RESULTS

Overall, 23% of students reported suicidal ideation. Among girls, having a caring friend was associated with lower odds of suicidal ideation only among those not using other drugs. Among boys, having a caring friend decreased the odds of suicidal ideation regardless of substance use.

CONCLUSIONS

Suicidal ideation is prevalent among middle school children. Substance abuse is associated with suicidal ideation; however, individual and community support can be protective. Interventions aimed at reducing suicidal behaviors among middle school students should account for the impact of substance use and help strengthen social support.

Isolated Voices: Perspectives of Teachers, School Nurses, and Administrators Regarding Implementation of Sexual Health Education Policy

BACKGROUND

Comprehensive sexual health education (SHE) reduces risky sexual behavior and increases protective behavior in adolescents. It is important to understand how professionals responsible for implementing SHE policy interpret state and local policy and what influences their commitment to formal SHE policy implementation.

METHODS

This descriptive study explored content and delivery of SHE policy in a rural, southwestern state with high levels of poverty, unintended adolescent pregnancy, and sexually transmitted infections. The social ecological model (SEM) was used to better understand levels of influence on the implementation of SHE policy.

RESULTS

We conducted telephone surveys with 38 teachers, 63 nurses, and 21 administrators in public secondary schools. There was substantial local variability in the scope and content of SHE curricula. Respondents identified significant barriers to the delivery of SHE content and minimal evaluation of whether educational objectives were met. Based on participant responses, community and organizational SEM levels had the greatest influence on SHE policy implementation, although examples of all SEM levels were identified.

CONCLUSIONS

Given perceived challenges regarding subject matter, successful SHE implementation at the local level requires committed stakeholders working in concert at the school and community levels, backed by strong policy commitment at the state level.

Spontaneous Chest Abscess Caused by Salmonella Enterica subsp. Arizonae in the Desert Southwest; A Case Report and Review of the Current Literature

Salmonella enterica subspecies arizonae is a rare pathogen but has been reported in the literature in immunosuppressed and rarely immunocompetent patients. Most disease states have been reported in animals and reptiles. Human exposure has resulted in a range of complications from skin and soft tissue infections to bacteremia and periprosthetic joint infections. Predisposing factors such as age, comorbidities, and use of Mexican folk healing practices increase the risk of developing an infection. S. arizonae has been associated with gastrointestinal infections in several parts of the country and on rare occasions have been isolated from skin and soft tissues, prosthetic joints, and empyema. Case: This is a unique case of a large de novo chest abscess that developed in a 59-year-old diabetic male from the Southwest region with cultures growing Salmonella enterica subspecies arizonae. This patient presented without predisposing factors and did not appear to be ill at the time of admission. He was treated successfully by aspirating the abscess along with a 2-week course of ceftriaxone intravenously.

Effectiveness of a Faculty Mentor Development Program for Scholarship at an Academic Health Center

INTRODUCTION

Mentors are in short supply at academic health centers (AHCs). The effectiveness of training mentors (without preselection for their research skills) to support faculty mentees in scholarly activities at AHCs is not well known.

METHODS

The University of New Mexico Health Sciences Center has a two-component program to develop effective mentors for scholarship for faculty mentees. It has an online component supplemented by an optional face-to-face (F2F) component. Study outcomes included changes in self-reported knowledge scores for online users and Mentoring Competency Assessment scores for F2F users.

RESULTS

One hundred five mentors, mostly women associate professors, used the online program. Online users demonstrated improvement in self-reported knowledge scores. Thirty-eight users additionally completed the F2F program-63% on a clinician-educator track and none with a National Institutes of Health-funded K-award mentee. The self-reported Mentoring Competency Assessment composite score rose from 4.3 ± 1.0 to 5.5 ± 0.8 (paired t = 7.37, df = 37, P < .001) for the F2F participants, with similar improvement noted in the clinician-educator subgroup.

DISCUSSION

Users of the online and F2F components of the program improved their self-assessed knowledge and mentoring skill, respectively, demonstrating the effectiveness of the program. Such programs may help AHCs enhance the scholarship and the diversity of their scientific and clinician-educator workforce.

Limitations to recovery following wildfire in dry forests of southern Colorado and northern New Mexico, USA

Climate warming is contributing to increases in wildfire activity throughout the western United States, leading to potentially long-lasting shifts in vegetation. The response of forest ecosystems to wildfire is thus a crucial indicator of future vegetation trajectories, and these responses are contingent upon factors such as seed availability, interannual climate variability, average climate, and other components of the physical environment. To better understand variation in resilience to wildfire across vulnerable dry forests, we surveyed conifer seedling densities in 15 recent (1988-2010) wildfires and characterized temporal variation in seed cone production and seedling establishment. We then predicted postfire seedling densities at a 30-m resolution within each fire perimeter using downscaled climate data, monthly water balance models, and maps of surviving forest cover. Widespread ponderosa pine (Pinus ponderosa) seed cone production occurred at least twice following each fire surveyed, and pulses of conifer seedling establishment coincided with years of above-average moisture availability. Ponderosa pine and Douglas-fir (Pseudotsuga menziesii) seedling densities were higher on more mesic sites and adjacent to surviving trees, though there were also important interspecific differences, likely attributable to drought and shade tolerance. We estimated that postfire seedling densities in 42% (for ponderosa pine) and 69% (for Douglas-fir) of the total burned area were below the lowest reported historical tree densities in these forests. Spatial models demonstrated that an absence of mature conifers (particularly in the interior of large, high-severity patches) limited seedling densities in many areas, but 30-yr average actual evapotranspiration and climatic water deficit limited densities on marginal sites. A better understanding of the limitations to postfire forest recovery will refine models of vegetation dynamics and will help to improve strategies of adaptation to a warming climate and shifting fire activity.

Establishment, Hybridization, Dispersal, Impact, and Decline of Diorhabda spp. (Coleoptera: Chrysomelidae) Released for Biological Control of Tamarisk in Texas and New Mexico

Three Diorhabda spp. tamarisk beetles (Coleoptera: Chrysomelidae) were established in Texas from 2003 to 2010 for biological control of tamarisk (Tamarix spp.): Mediterranean tamarisk beetles, D. elongata (Brullé) from Greece, also established in New Mexico; subtropical tamarisk beetles, D. sublineata (Lucas) from Tunisia; and larger tamarisk beetles, D. carinata (Faldermann) from Uzbekistan. More than one million tamarisk beetles were released at 99 sites. Species establishment success ranged from 52 to 83%. All three species now co-occur in New Mexico with the northern tamarisk beetles, D. carinulata (Desbrochers). A phenotypic hybrid scoring system was developed to assess Diorhabda phenotype distributions and character mixing in hybrid zones. Widespread field populations of bispecific hybrid phenotypes for D. carinata/D. elongata and D. sublineata/D. elongata rapidly appeared following contact of parental species. Initial distributions and dispersal of Diorhabda spp. and hybrids are mapped for Texas, New Mexico, Oklahoma, and Kansas, where they produced large-scale tamarisk defoliation and localized dieback for 3-4 yr. However, populations subsequently severely declined, now producing only isolated defoliation and allowing tamarisk to recover. Diorhabda sublineata and D. elongata temporarily produced nontarget spillover defoliation of ornamental athel, Tamarix aphylla (L.) Karst, along the Rio Grande. Hybrid phenotypes were generally bimodally distributed, indicating some degree of reproductive isolation. Additional diagnostic phenotypic characters in males allowed more precise hybrid scoring. Character mixing in some hybrid populations approached or reached that of a hybrid swarm. The significance of hybridization for tamarisk biocontrol is discussed.

Family, School, and Peer Support Are Associated With Rates of Violence Victimization and Self-Harm Among Gender Minority and Cisgender Youth

PURPOSE

Gender minority (GM) youth experience high rates of violence, and research on protective factors to reduce violence victimization and self-harm is lacking. The purpose of this study was to determine how family, school, peer, and community support influenced rates of violence victimization and self-harm among GM and cisgender adolescents.

METHODS

This research uses data from the 2017 New Mexico Youth Risk and Resiliency Survey (N = 18,451). The main independent variable was gender, dichotomized into GM and cisgender, and the secondary independent variables were family, school, community, and peer support. Dependent variables were sexual and dating violence, suicide attempts, and nonsuicidal self-injury. Logistic regression models were built for the four dependent variables, including demographics, support scores, and interaction terms between gender and support.

RESULTS

Six percent of high school students in New Mexico identified as GM are unsure of their gender. GM students experienced higher rates of violence and self-harm and lower levels of support than cisgender students. Among all students, family support was associated with lower odds of sexual violence and self-harm, while school support was associated with lower odds of dating violence and nonsuicidal self-injury. There were significant interactions between gender, violence, and support. The protective effects of support were less pronounced for GM students than for cisgender students.

CONCLUSIONS

Family and school support are associated with lower rates of some forms of violence and self-harm among adolescents. Additional support may be necessary to reduce harm among GM adolescents, who are at higher risk for violence and its sequelae.

Psychometric evaluation of the power of food scale in a diverse college sample: Measurement invariance across gender, ethnicity, and weight status

The Power of Food Scale (PFS) is an instrument designed to examine individual differences in the drive to eat for pleasure (as opposed to in response to physiological hunger) and the effect of living in an obesogenic environment. Previous research supports the validity and reliability of the PFS, however, it had yet to be validated in an ethnically diverse college sample. The purpose of the current study was to test the factor structure and measurement invariance of the PFS across gender, ethnicity, and weight status. A sample of 432 college students completed the PFS (males=113, females = 319; non-Hispanic white=181, Hispanic=251; non-overweight=302, overweight=130). Confirmatory factor analysis was used to test a second-order, 3-factor (food available, food present, food tasted) structure of the PFS in each group separately (males, females, Hispanic, non-Hispanic white, non-overweight, and overweight) and tests of measurement invariance were conducted to test the equivalency of the measure across gender, ethnicity, and weight status. Results supported the measure's original factor structure (second-order, 3-factor model) and indicated that the measure is equivalent across each of these groups, respectively. Although the small, unbalanced groups may impact the stability of the findings, the results nonetheless suggest that the PFS is a psychometrically valid measure in a diverse college sample, and that mean comparisons on this measure are meaningful across gender, ethnicity, and weight status. Given the measurement invariance of the PFS, there is support for use of the PFS among diverse college students in future work.

Integrating community health representatives with health care systems: clinical outcomes among individuals with diabetes in Navajo Nation

BACKGROUND

We studied the impact of Community Outreach and Patient Empowerment (COPE) intervention to support Community Health Representatives (CHR) on the clinical outcomes of patients living with diabetes in the Navajo Nation extending into the States of Arizona, Utah, and New Mexico. The COPE intervention integrated CHRs into healthcare teams by providing a structured approach to referrals and home visits.

METHODS

We abstracted routine clinical data from the Indian Health Service's information system on individuals with diabetes mellitus seen at participating clinical sites from 2010 to 2014. We matched 173 COPE participants to 2880 patients with similar demographic and clinical characteristics who had not participated in COPE. We compared the changes in clinical outcomes between the two groups using linear mixed models.

RESULTS

Over the four years of the study, COPE patients had greater improvements in glycosylated hemoglobin (- 0.56%) than non-COPE participants (+ 0.07%) for a difference in differences of 0.63% (95% confidence interval (CI): 0.50, 0.76). Low-density lipoprotein fell more steeply in the COPE group (- 10.58 mg/dl) compared to the non-COPE group (- 3.18 mg/dl) for a difference in differences of 7.40 mg/dl (95%CI: 2.00, 12.80). Systolic blood pressure increased slightly more among COPE (2.06 mmHg) than non-COPE patients (0.61 mmHg). We noted no significant change for body mass index in either group.

CONCLUSION

Structured outreach by Community Health Representatives as part of an integrated care team was associated with improved glycemic and lipid levels in the target Navajo population.

Total Recoverable Aluminum: Not Totally Relevant for Water Quality Standards

A large water quality data set, representing more than 100 surface-water locations sampled from 2007 to 2017 in the Los Alamos area of New Mexico, USA's Pajarito Plateau, was assembled to evaluate Al concentrations in unfiltered and filtered samples. Aluminum concentrations often exceeded United States Environmental Protection Agency (USEPA) and New Mexico ambient water quality criteria (AWQC), regardless of filter size and sample location. However, AWQC are based on laboratory toxicity studies using soluble Al salts and do not reflect natural conditions in Pajarito Plateau surface waters. The plateau is predominately covered by glassy and recrystallized volcanic ashes (e.g., Bandelier Tuff) containing colloidal to sand-sized aluminosilicates. Samples from natural background drainages and areas downstream of developed regions exhibited similar Al concentrations, suggesting that AWQC exceedances are caused by naturally elevated Al concentrations. Solubility calculations indicated that most samples were oversaturated with respect to amorphous Al(OH)₃ (s). Therefore, AWQC exceedances are likely artifacts of the "total recoverable" sample preparation, which includes acidification and partial digestion, thereby liberating nonbioavailable Al from aluminosilicates. Accordingly, Al concentrations were strongly associated with suspended sediment concentrations (SSCs), implying that aluminosilicates in suspended sediment contributed to AWQC exceedances and Al oversaturation. Solid-phase particle characterization, using X-ray diffraction (XRD) and scanning electron microscopy with electron dispersive spectroscopy (SEM/EDS) did not identify potentially bioavailable amorphous Al(OH)₃ (s) in any sample tested. Thus, current sample collection and analysis protocols should not be used to evaluate attainment of Al AWQC on the Pajarito Plateau or locations where aluminosilicates are substantial contributors to total recoverable Al. A sample preparation method (e.g., pH 4 extraction) capable of differentiating nonbioavailable and bioavailable forms of Al is recommended. Otherwise, current New Mexico and USEPA sample preparation approaches will continue to generate artifactual AWQC exceedances in surface waters that contain aluminosilicates.

Knockdown Resistance-Associated Mutations Dominate Populations of the Common Bed Bug (Hemiptera: Cimicidae) Across the South Central United States

Despite awareness of the mutations conferring insecticide resistance in the bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), within the United States few studies address the distribution and frequency of these. Within the United States, studies have focused on collections made along the East Coast and Midwest, documenting the occurrence of two mutations (V419L and L925I) within the voltage-gated sodium channel α-subunit gene shown to be associated with knockdown resistance (kdr) to pyrethroids. Here, the distribution and frequency of the V419L and L925I site variants is reported from infestations sampled within Oklahoma and its immediately adjacent states. Additionally, the presence of a mutation previously undocumented in the United States (I935F) is noted. While novel in the United States, this mutation has previously been reported in Australian and Old World populations. No infestations were found to harbor wild-type individuals, and hence susceptible, at each of the three sites. Instead, ~21% were found to possess the resistant mutation at the L925I site (haplotype B), ~77% had mutations at both the V419L and L925I sites (haplotype C), and 2% possessed the mutation at the L936F site (haplotype Ab). The high frequency of haplotype C corresponds to previous studies in the United States, and contrasts dramatically with those of the Old World and Australia. The data presented here provide insight into the contemporary occurrence of kdr-associated insecticide resistance in the South Central United States, a region for which data have previously been absent. These data suggest that New World and Old World/Australian infestations are likely to have originated from different origins.

Autophagy, Inflammation, and Metabolism (AIM) Center in its second year

The NIH-funded center for autophagy research named Autophagy, Inflammation, and Metabolism (AIM) Center of Biomedical Research Excellence, located at the University of New Mexico Health Science Center is now completing its second year as a working center with a mission to promote autophagy research locally, nationally, and internationally. The center has thus far supported a cadre of 6 junior faculty (mentored PIs; mPIs) at a near-R01 level of funding. Two mPIs have graduated by obtaining their independent R01 funding and 3 of the remaining 4 have won significant funding from NIH in the form of R21 and R56 awards. The first year and a half of setting up the center has been punctuated by completion of renovations and acquisition and upgrades for equipment supporting autophagy, inflammation and metabolism studies. The scientific cores usage, and the growth of new studies is promoted through pilot grants and several types of enablement initiatives. The intent to cultivate AIM as a scholarly hub for autophagy and related studies is manifested in its Vibrant Campus Initiative, and the Tuesday AIM Seminar series, as well as by hosting a major scientific event, the 2019 AIM symposium, with nearly one third of the faculty from the International Council of Affiliate Members being present and leading sessions, giving talks, and conducting workshop activities. These and other events are often videostreamed for a worldwide scientific audience, and information about events at AIM and elsewhere are disseminated on Twitter and can be followed on the AIM web site. AIM intends to invigorate research on overlapping areas between autophagy, inflammation and metabolism with a number of new initiatives to promote metabolomic research. With the turnover of mPIs as they obtain their independent funding, new junior faculty are recruited and appointed as mPIs. All these activities are in keeping with AIM's intention to enable the next generation of autophagy researchers and help anchor, disseminate, and convey the depth and excitement of the autophagy field.

Advances in Semiochemical Repellents to Mitigate Host Mortality From the Spruce Beetle (Coleoptera: Curculionidae)

We tested 3-methyl-2-cyclohexen-1-one (MCH) and novel semiochemicals as potential spruce beetle (Dendroctonus rufipennis Kirby) (Coleoptera: Curculionidae, Scolytinae) repellents over multiple years in Utah and Colorado trapping bioassays. MCH is a known spruce beetle repellent and our testing revealed Acer kairomone blend (AKB) and isophorone plus sulcatone as repellents. We subsequently tested these semiochemicals for area and single tree protection to prevent spruce beetle attacks at locations in Utah, Colorado, Wyoming, New Mexico, and Alaska. Individual tree protection trials found MCH-AKB provided significant protection against spruce beetle attacks in the southern Rocky Mountains but not in Alaska. Adding sulcatone or doubling MCH-AKB pouches did not further enhance protection. A degree of protection was extended to spruce at least 10 m distant from the repellents, including in Alaska. Tree diameter was not a significant covariate among treated trees but was positively correlated with the probability of infestation for surrounding spruce. In area protection trials, spruce in control plots were 2.4 times more likely to be in a higher severity attack class compared with spruce in plots treated with MCH-AKB pouches deployed at 30 sets per hectare. Tree diameter had a significant, positive relationship to the probability of infestation. We found MCH-AKB to offer a high degree of protection against beetle attack in Engelmann spruce (Picea engelmannii Parry ex Engelm.) (Pinales: Pinaceae) (Picea engelmannii Parry ex Engelm.) (Pinales: Pinaceae), especially for single tree protection (66% of control trees were strip- or mass-attacked compared with 6% of repellent-treated trees). AKB requires registration and labeling, however, before this economical and environmentally benign semiochemical can be used operationally.

A Systems Approach To Assess Trade Dependencies in U.S. Food-Energy-Water Nexus

We present a network model of the United States (U.S.) interstate food transfers to analyze the trade dependency with respect to participating regions and embodied irrigation impacts from a food-energy-water (FEW) nexus perspective. To this end, we utilize systems analysis methods including the pointwise mutual information (PMI) measure to provide an indication of interdependencies by estimating probability of trade between states. PMI compares observed trade with a benchmark of what is statistically expected given the structure and flow in the network. This helps assess whether dependencies arising from empirically observed trade occur due to chance or preferential attachment. The implications of PMI values are demonstrated by using Texas as an example, the largest importer in the U.S. grain transfer network. We find that strong dependencies exist not only just with states (Kansas, Oklahoma, Nebraska) providing high volume of transfer to Texas but also with states that have comparatively lower trade (New Mexico). This is due to New Mexico's reliance on Texas as an important revenue source compared to its other connections. For Texas, import interdependencies arise from geographical proximity to trade. As these states primarily rely on the commonly shared High Plains aquifer for irrigation, overreliance poses a risk for water shortage for food supply in Texas. PMI values also indicate the capacity to trade more (the states are less reliant on each other than expected), and therefore provide an indication of where the trade could be shifted to avoid groundwater scarcity. However, some of the identified states rely on GHG emission intensive fossil fuels such as diesel and gasoline for irrigation, highlighting a potential tradeoff between crop water footprint and switching to lower emissions pumping fuels.

Place of Strength: Indigenous Artists and Indigenous Knowledge is Prevention Science

The Place of Strength (PoS) project represents an effort to Indigenize program evaluation with Indigenous communities by melding art with prevention science. We propose that Native artists as evaluators: (a) opens avenues of communication for Indigenous perspectives; (b) provides opportunities to capture spiritual, relational, and emotional impacts of prevention programming; and (c) maintains Indigenous processes, language, and values at the center of knowledge production. The New Mexico Tribal Prevention Project (NMTPP) funded seven Southwestern tribes to develop substance abuse prevention programs. In response to their expressed negative experiences with evaluation of prevention strategies, NMTPP piloted PoS. PoS shifted systematic knowledge paradigms to Tribal thought, values, and perspectives embodied in art. Art exists in Native communities as a way of documenting lifeways and historical experiences through various cultural forms. We share the process of collaborating with Native artists to document the impact of substance abuse prevention initiatives through their art within a community context. We offer concepts derived from this project as a community psychology model for re-conceptualizing evaluation utilizing Indigenous knowledge.

Distribution of a New Invasive Species, Sipha maydis (Heteroptera: Aphididae), on Cereals and Wild Grasses in the Southern Plains and Rocky Mountain States

Sipha maydis Passerini (Heteroptera: Aphididae) is a cereal pest with an extensive geographical range that includes countries in Europe, Asia, Africa, and South America. Reports of S. maydis in the United States have been infrequent since it was first detected in California, 2007. Two studies, focused (NW CO) and multistate (OK, TX, NM, CO, UT, WY), were conducted to determine the distribution and host range of S. maydis in the Rocky Mountain and Southern Plains states over a 3-yr period, 2015-2017. In 2015, focused sampling in NW Colorado found S. maydis at 59% of the 37 sites, primarily on wheat. Sipha maydis did not survive extreme winter temperatures from late December 2015 to early January 2016 that ranged from -9.0 to -20.9°C over a 9-d period, which resulted in no aphids detected in 2016. In the multistate study, S. maydis occurred in 14.6% of 96 sites sampled in 2015, 8% of 123 sites in 2016, and 9% of 85 sites in 2017 at wide range of altitudes from 1,359 to 2,645 m. Sipha maydis occurred mainly in NW and SW Colorado and NE New Mexico along with a few sites in NE Colorado, SE Utah, and SE Wyoming. This aphid mainly infested wheat followed by a variety of eight wild grass species. No parasites, predators, sexual morphs, or significant plant damage occurred at the sites. Sipha maydis utilized 14 hosts in the United States including 8 new host records, which expands its host range to 52 plant species worldwide. Sipha maydis may be of concern to wheat, barley, and sorghum production in the United States if its populations continue to increase.

Primary Care Practices' Ability to Report Electronic Clinical Quality Measures in the EvidenceNOW Southwest Initiative to Improve Heart Health

IMPORTANCE

The capability and capacity of primary care practices to report electronic clinical quality measures (eCQMs) are questionable.

OBJECTIVE

To determine how quickly primary care practices can report eCQMs and the practice characteristics associated with faster reporting.

DESIGN, SETTING, AND PARTICIPANTS

This quality improvement study examined an initiative (EvidenceNOW Southwest) to enhance primary care practices' ability to adopt evidence-based cardiovascular care approaches: aspirin prescribing, blood pressure control, cholesterol management, and smoking cessation (ABCS). A total of 211 primary care practices in Colorado and New Mexico participating in EvidenceNOW Southwest between February 2015 and December 2017 were included.

INTERVENTIONS

Practices were instructed on eCQM specifications that could be produced by an electronic health record, a registry, or a third-party platform. Practices received 9 months of support from a practice facilitator, a clinical health information technology advisor, and the research team. Practices were instructed to report their baseline ABCS eCQMs as soon as possible.

MAIN OUTCOMES AND MEASURES

The main outcome was time to report the ABCS eCQMs. Cox proportional hazards models were used to examine practice characteristics associated with time to reporting.

RESULTS

Practices were predominantly clinician owned (48%) and in urban or suburban areas (71%). Practices required a median (interquartile range) of 8.2 (4.6-11.9) months to report any ABCS eCQM. Time to report differed by eCQM: practices reported blood pressure management the fastest (median [interquartile range], 7.8 [3.5-10.4] months) and cholesterol management the slowest (median [interquartile range], 10.5 [6.6 to >12] months) (log-rank P < .001). In multivariable models, the blood pressure eCQM was reported more quickly by practices that participated in accountable care organizations (hazard ratio [HR], 1.88; 95% CI, 1.40-2.53; P < .001) or participated in a quality demonstration program (HR, 1.58; 95% CI, 1.14-2.18; P = .006). The cholesterol eCQM was reported more quickly by practices that used clinical guidelines for cardiovascular disease management (HR, 1.35; 95% CI, 1.18-1.53; P < .001). Compared with Federally Qualified Health Centers, hospital-owned practices had greater ability to report blood pressure eCQMs (HR, 2.66; 95% CI, 95% CI, 1.73-4.09; P < .001), and clinician-owned practices had less ability to report cholesterol eCQMs (HR, 0.52; 95% CI, 0.35-0.76; P < .001).

CONCLUSIONS AND RELEVANCE

In this study, time to report eCQMs varied by measure and practice type, with very few practices reporting quickly. Practices took longer to report a new cholesterol measure than other measures. Programs that require eCQM reporting should consider the time and effort practices must exert to produce reports. Practices may benefit from additional support to succeed in new programs that require eCQM reporting.

Quantification of Elemental Contaminants in Unregulated Water across Western Navajo Nation

The geologic profile of the western United States lends itself to naturally elevated levels of arsenic and uranium in groundwater and can be exacerbated by mining enterprises. The Navajo Nation, located in the American Southwest, is the largest contiguous Native American Nation and has over a 100-year legacy of hard rock mining. This study has two objectives, quantify the arsenic and uranium concentrations in water systems in the Arizona and Utah side of the Navajo Nation compared to the New Mexico side and to determine if there are other elements of concern. Between 2014 and 2017, 294 water samples were collected across the Arizona and Utah side of the Navajo Nation and analyzed for 21 elements. Of these, 14 elements had at least one instance of a concentration greater than a national regulatory limit, and six of these (V, Ca, As, Mn, Li, and U) had the highest incidence of exceedances and were of concern to various communities on the Navajo Nation. Our findings are similar to other studies conducted in Arizona and on the Navajo Nation and demonstrate that other elements may be a concern for public health beyond arsenic and uranium.

Metal(loid)s in Cucurbita pepo in a Uranium Mining Impacted Area in Northwestern New Mexico, USA

More than 500 unreclaimed mines and associated waste sites exist on the Navajo Nation reservation as a result of uranium (U) mining from the 1940s through the 1980s. For this study, the impact of U-mine waste on a common, locally grown crop food was examined. The goal of this site-specific study was to determine metal(loid) concentration levels of arsenic (As), cadmium (Cd), cesium (Cs), molybdenum (Mo), lead (Pb), thorium (Th), U, vanadium (V) and selenium (Se) in Cucurbita pepo Linnaeus (squash), irrigation water, and soil using inductively coupled plasma-mass spectrometry. The concentrations of metal(loid)s were greatest in roots > leaves > edible fruit (p < 0.05), respectively. There were significant differences between metal(loid)s in squash crop plot usage (<5 years versus >30 years) for V (p = 0.001), As (p < 0.001), U (p = 0.002), Cs (p = 0.012), Th (p = 0.040), Mo (p = 0.047), and Cd (p = 0.042). Lead and Cd crop irrigation water concentrations exceeded the United States Environmental Protection Agency (USEPA) Maximum Contaminant Levels for drinking water for those metals. Edible squash concentration levels were 0.116 mg/kg of As, 0.248 mg/kg of Pb, 0.020 mg/kg of Cd, and 0.006 mg/kg of U. Calculated human ingestion of edible squash did not exceed Provisional Tolerable Weekly Intake or Tolerable Upper Limit levels from intake based solely on squash consumption. There does not appear to be a food-ingestion risk from metal(loid)s solely from consumption of squash. Safer access and emphasis on consuming regulated water was highlighted. Food intake recommendations were provided. Continued monitoring, surveillance, and further research are recommended.
