Vertento® (isocycloseram) en Algodón: Eficacia, Selectividad Parcial y Uso Dentro del MIP
No full textEl registro reciente de Vertento® (isocicloseram; Grupo 30 de IRAC) introduce un nuevo modo de acción para el manejo de Lygus en el algodón de Arizona. Estudios de campo muestran un control excelente y consistente a una dosis de 1.6 onzas por acre (≈120 mL/ha), con actividad residual de dos semanas o más. Vertento se clasifica como un insecticida parcialmente selectivo (“caja amarilla”) dentro del sistema MIP de base biológica de Arizona, con efectos intermedios sobre organismos benéficos no objetivo. Sus impactos sobre depredadores son menores que los de insecticidas organofosforados, lo que lo convierte en una opción eficaz para el manejo de Lygus que apoya el manejo de la resistencia y reduce el riesgo de brotes secundarios.Documents in the Arizona Pest Management Center collection are made available by the Arizona Pest Management Center (APMC) and the University Libraries at the University of Arizona.

Analysis of Datalogging from Participants in the Conexiones Project
No full textThe goal of fitting hearing aids is to improve a patient’s quality of life by facilitating their access to sound. For adult patients with a newly-identified hearing loss, difficulty understanding speech in their daily lives is typically their most pressing concern, and what ultimately drives them to pursue amplification. Hearing aids perform best in situations with little to no background noise competing with the primary speech signal. Therefore, patients who spend the largest proportion of their time in those favorable listening conditions are predicted to have success with hearing aids, in lieu of other circumstances. While the decision to pursue amplification is made on an individual, interpersonal (patient-provider), and interfamilial basis, adults who are senior-age and older are most commonly thought of as ideal hearing aid candidates as a group, both because of the high prevalence of age-related hearing loss, and due to the assumption that advanced age correlates with a quieter lifestyle (Humes et al., 2018). While this generalization is not unfounded, studies on the listening environments that older adults inhabit rarely investigate possible acoustic lifestyle differences between adults of different social, linguistic, cultural, and economic backgrounds. This project will give a broad overview of the current literature on the listening environments older adults live in, particularly those who use hearing aids. Current gaps in the literature will be discussed, with special attention paid to the lack of demographic diversity in most prior studies. This will establish the groundwork for the primary goal of this project, which is to examine the hearing aid usage data from the underserved community that was recently the focus of a study by Coco et al. (2023) at the University of Arizona. Patterns in hearing aid usage, especially in regards to the listening environments participants wore their hearing aids in, will be synthesized and compared to previous studies on this topic. Of particular interest is the study from Humes et al. (2018), as it also utilized the environmental classification system from hearing aids to investigate the listening environments the participants experienced. These two samples will be directly compared in order to discuss how a more diverse sample of acoustic lifestyles could impact audiologic rehabilitation in theory and practice.Dissertation not available (per author’s request

Chronic Opioid Exposure and Peripheral Respiratory Outcomes
No full textIn these studies, the hypothesis that chronic opioid exposure promotes peripheral respiratory adverse health outcomes was tested. The first set of clinical studies explored prenatal opioid exposure (POE) and pulmonary outcomes in offspring. The second set of preclinical studies investigated the effects of chronic opioid exposure on airway remodeling, inflammation, pulmonary edema, and lung function, in an adult mouse model. Although we did not use an animal model of POE, our findings that POE influenced respiratory outcomes longitudinally into childhood, inspired preclinical studies for investigation of respiratory disease in a rodent model of chronic opioid exposure. We started with a seven-day model of chronic opioid exposure in mice since it is a widely used protocol for evaluation of physiological opioid dependence. Our first aim was to investigate whether in utero opioid exposure promoted the development of adverse respiratory outcomes within the first five years of childhood. Bioinformatic methods were used to query the 165 million record PearlDiver-Mariner patient database records for adverse respiratory diagnoses after POE. POE significantly impacted the risk for negative respiratory outcomes within the first five years of life, most notably amongst full-term births, although preterm births were also affected. POE resulted in tachypnea and respiratory distress in both groups. Full-term births were at an increased risk for bronchiolitis and apnea, whereas preterm births were at an increased risk for asthma. Full-term infants exposed to prenatal opioids were diagnosed with respiratory outcomes at earlier ages than their unexposed counterparts and appeared more like preterm infants. These data suggest careful monitoring of full-term infants with a history of POE for respiratory outcomes in early life. Findings from the patient database studies inspired additional preclinical studies that had advantages over limitations from the patient data. For example, we were not able to distinguish the effects of individual opioids in our PearlDiver study. With our preclinical mouse model of chronic opioid exposure, we were able to individually study the effects of fentanyl, morphine, and oxycodone separately. We studied the outcomes of pulmonary inflammation, airway remodeling edema, and lung function. Chronic opioid exposure increased inflammation in females, but not general factors associated with tissue remodeling. We observed increased tissue remodeling factor expression in males, but not inflammation. Our model of chronic opioid exposure did not result in pulmonary edema. Indeed, chronic morphine exposure decreased pulmonary vascular permeability in males and females. Chronic fentanyl and oxycodone did not significantly affect pulmonary vascular permeability. Thus, our model of chronic opioid exposure promoted lung inflammation and tissue remodeling in a sex and drug dependent manner but does not directly promote pulmonary edema. Lastly, chronic opioid exposure induced heterogenous changes in lung function in alignment with phenotypes of lung disease. Together, these findings suggest that chronic opioid exposure adversely impacts respiratory health both in developing lungs and in mature lungs. These studies can be used to add to the evidence to search for non-opioid therapies and to guide clinicians to monitor their opioid-prescribed patients for respiratory health outcomes
Quantifying and Comparing Crop Water Productivity in Organic vs. Conventional Iceberg Lettuce, Yuma, AZ
No full textThis study quantified Crop Water Productivity (CWP) in organic and conventional iceberg lettuce systems at the University of Arizona Yuma Agricultural Center during the 2024–2025 season. Both systems were managed under subsurface drip irrigation using sensor-based and traditional irrigation scheduling strategies. Results showed that conventional lettuce produced about 40–50% more yield per unit of crop evapotranspiration than the organic system; this difference may be related to differences in crop growth and nutrient availability. While short-term CWP was higher under conventional management, organic systems may enhance soil structure, water-holding capacity, and infiltration over time; however, these soil changes were not measured in this single-season study. Sensor-based irrigation scheduling in most cases improved irrigation water-use efficiency across both systems, demonstrating that precision irrigation technologies can help Yuma growers make better use of water resources. Combining precision irrigation with organic farm practices that focus on soil management and improving soil properties offers a promising path toward sustaining productivity and conserving water in Yuma’s desert agriculture
