An increase in population and need to protect the planet has created many initiatives and research goals in developing alternatives methods of fueling. Federal and state policies have provided a push for industries to find ways to of reducing their impact on the environment while maintaining competitiveness. In the sector of alternative fuels, large policies such as the Renewable Fuel Standards (RFS) in the United States are making goals to reduce vehicular fuel from coal and oil, and focus on alternative fuels such as ethanol and biodiesel. Along with the RFS and other federal policies, states are introducing independent initiatives to promote the use of alternative fuels.

Research has shown that other crops besides corn can feasibly be used to produce ethanol for fuel use. One of the major crops of interest currently is switchgrass (Panicum Virgatum L.) because of its ability to grow under a variety of weather conditions and soil types. Switchgrass does not require as much maintenance as corn and is a perennial grass that can have high yielding fields for up to 9 years.

This report focuses on the impacts from using switchgrass-derived ethanol to meet the state of Arizona’s policy to have government fleet vehicles operating on alternative fuels. The study uses a life cycle assessment (LCA) approach to evaluate 22 million gallons of ethanol produced in Arizona and stored at fueling stations for use. Impacts in land use, global warming, and water quality are evaluated using software tools and databases in Ecoinvent and Simapro.

The results of the study indicate that the cultivation and harvest phase of the process will contribute the most to negative environmental impacts. According to the study, application of heavy nutrient fertilizer and the machinery needed for the additional agriculture have the potential to contribute over 36 million moles of hydrogen and 89 million CTU eq. to the air, soil, and water.

Background: The shortage of providers, therapists, and long waiting times for appointments in the United States is growing. Mental health technology applications (apps) expand the strategies available to people with mental health conditions to achieve their goals for well being through self-management of symptoms.

Methods: A project was undertaken at an outpatient behavioral setting in urban Arizona to determine the use and effectiveness of a mental health app called insight timer to reduce anxiety symptoms. Adult clients with anxiety symptoms were provided with the insight timer app to use over a period of eight weeks. Anxiety was evaluated with the GAD-7 scale initially and after the eight weeks of app use. Usability and the quality of the app were assessed with an app rating scale at the end of the eight weeks.

Results: Findings of the Wilcoxon Signed Ranks test indicated changes in pre and posttest assessment scores as significant (p = .028), which is a significant reduction in anxiety among seven clients who completed the 8-week intervention. the mean TI score was 15.57 (SD = 4.9), and the mean T2 score was 7.71 (SD = 5.7). Besides, Cohen's effect size value (d = 1.465) suggested large clinical significance for GAD7 in pre and posttest.

Discussion: Evidence suggests that the use of an evidence-based app can effectively reduce anxiety symptoms and improve the quality of life. The use of mental health apps like insight timer could reduce health care costs associated with unnecessary hospital admissions as well as re-hospitalizations. The routine use of apps such as the insight timer may also be beneficial to all the clients who have anxiety symptoms in outpatient as well as inpatient settings.

The coronavirus (COVID-19) pandemic led to disruptions in the food supply and high rates of unemployment and under-employment, both in Arizona and nationally. These emergencies required food assistance programs to adapt quickly and in unprecedented ways by relaxing eligibility criteria, improvising on delivery modalities, and increasing benefits. To examine food assistance program participation during the pandemic, we collected data from a representative sample of 620 Arizona households. The sample was drawn from across Arizona in July-August 2020 using an online survey. This brief provides the summary for participation in key food assistance programs, namely, the Supplementary Nutrition Assistance Program (SNAP), the Special Supplemental Program for Women Infants and Children (WIC), School Food Programs, and the emergency food assistance provided through food pantries.

With more than 19 million confirmed COVID-19 cases across the United States1 and over 500,000 in Arizona as of December 2020, the ongoing pandemic has had devastating impacts on local, national, and global economies. Prior to the pandemic (February 2020), based on U.S. Bureau of Labor Statistics data, the unemployment rate in Arizona was 6.5%, compared to 4.9% at the national level.3 Since the beginning of the COVID-19 pandemic (March 2020), the United States has experienced striking increases in the unemployment rate, reaching 13.2% in April. Similarly, in Arizona, the unemployment rate jumped to over 13.5% in April. The unemployment rates have since declined both nationally and in Arizona but remain higher compared to February 2020. In November 2020 (the most recent data available), the national unemployment rate was 6.7%, while in Arizona the rate was 7.8%—the 10th highest unemployment rate among all U.S. states.

Purpose: To assess the burnout levels of mental health workers and to evaluate the effectiveness of promoting self-care practices in improving their well-being and resiliency. Background and Significance: Burnout is highly prevalent among mental health workers due to the nature of their work and the population of patients they serve. Turnover has been a significant problem within this specialty for decades. Before the COVID-19 pandemic, the mental health workforce was projected to experience shortage by 2025. The pandemic will likely worsen this. Evidence from literature supports the effectiveness of promoting self-care towards the development of resiliency and well-being in addressing burnout among healthcare workers. Methods: The Maslach Burnout Inventory – Human Services Survey (MBI-HSS) was used to assess the burnout levels of mental health workers in a psychiatric hospital in Arizona pre- and post-intervention. Educational modules were provided for each participant to review. They were asked to perform at least one self-care activity and to utilize the tools in the Provider Resilience application every week for four weeks. Results: Pre-intervention surveys indicated moderate levels of emotional exhaustion (m=20.71) and depersonalization (m=9.29) and high levels of personal accomplishment (m=28.71). Improvements were seen on emotional exhaustion (m=18.86), depersonalization (m=6.43), and personal accomplishment (m=33.86) were seen post-intervention. Conclusion: Although the results were not statistically significant due to small sample size, the improvements seen on two out of three components of burnout (emotional exhaustion and depersonalization) indicated that awareness of burnout levels and self-care practices contribute to improving the well-being of mental health workers.

Introduction: The purpose of this project was to evaluate a tablet-based documentation application for massive transfusion protocols (MTPs). Methods: 13 trauma nurses at a level-one pediatric trauma center were randomly assigned to use paper documentation (n=5) or the tablet-based application (n=8) during simulated MTPs. Documentation completeness was compared using an independent t-test. Tablet users completed a system usability survey (SUS). Results: Documentation of blood product volumes and times significantly improved with the tablet (p=<0.001 and p=0.001 respectively). The tablet received a mean SUS score of 89%. Discussion: A tablet-based application has potential to improve real-time documentation of MTPs.

Successful management of pediatric procedures is challenging. Many procedures have a detailed list of pre-procedural requirements and post-procedural pain control regimens. Patients and families often get lost in the many requirements needed before scheduling the procedure and often delay intervention. This delay can cost both the families and facility time and money but often leave the patient needlessly suffering. Inadequate pain control results in emergency room (ER) visits or hospital admissions for acute postoperative pain management. The opioid epidemic has significantly impacted postoperative opioid prescriptions at discharge. The limited prescriptions available after discharge, paired with inadequate understanding and support of discharge postoperative instructions by the family, result in increased acute postoperative pain management admissions. Postoperative pain is the leading cause of hospital readmissions within 48 hours of discharge. These ER visits are typically for issues that are easily addressed at home. Teach-back methods have shown to be the cornerstone of education, resulting in knowledge gained and increased pain regimen adherence. A literature review exploring current evidence regarding postoperative pain control and interventions coupled with teach-back was conducted to address this concern, and an evidenced-based intervention is proposed.
