Screening for depression among a sample of US college students who engage in recreational prescription opioid misuse

© 2020 The Author(s). Background: Among student populations, literature has identified associations between prescription opioid misuse and symptoms of depression such as hopelessness, sadness, and emotional pain. Thus far, existing literature has yet to investigate associations between prescription opioid misuse and depression using validated screening instruments for depression when exploring such associations. The purpose of this study was to utilize a validated screening tool to explore quantifiable presence of depression among college students who engage in recreational prescription opioid misuse (RPOM). Additionally, gender differences in depression and co-occurring substance use are examined. Methods: Students (n = 104) of a large university in the Southeastern United States who reported RPOM within the past 6 months completed instrumentation assessing demographics, substance use, as well as, screening tools for depression and possible opioid use disorder (OUD). Results: Positive depression screens were significantly higher among females, however, nearly 56% of participants screened positive for major depression. Though high levels of co-occurring substance use were observed among the entire sample, males were significantly more likely to report cocaine use, more frequent use of alcohol and marijuana, as well as, exhibit a positive screen for disordered opioid use, at a rate 5 times that of their female counterparts. Conclusion: Students who engage in RPOM are a particularly heightened-risk subsample of the college population who exhibit high levels of depressive symptomatology and substance use behavior. Targeted programming and further investigations are needed among this specific population. Future studies are encouraged to utilize validated instruments when assessing depression among students

Tetra­iodido[methyl­enebis(diphenyl­phosphine oxide)-κ2 O:O′]tin(IV) chloro­form solvate

The title compound, [SnI4(C25H22O2P2)]·CHCl3, crystallized from a chloro­form solution of SnI4 and the diphosphine CH2(PPh2)2 exposed to air. The monomeric complex displays a distorted octa­hedral coordinaton for the tin(IV) atom with average Sn—I and Sn—O bond lengths of 2.79 (2) and 2.15 (1) Å, respectively

Development and Application of an Interdisciplinary Rapid Message Testing Model for COVID-19 in North Carolina

Introduction From the onset of the COVID-19 pandemic, public health officials have sought to develop evidence-based messages to reduce COVID-19 transmission by communicating key information to media outlets and the public. We describe the development of an interdisciplinary rapid message testing model to quickly create, test, and share messages with public health officials for use in health campaigns and policy briefings. Methods An interdisciplinary research team from the University of North Carolina at Chapel Hill assembled in March 2020 to assist the state health department in developing evidence-based messages to influence social distancing behaviors in the state. We developed and iteratively executed a rapid message testing model; the components of the 4-step model were message creation, survey development, survey administration, and analysis and presentation to health department officials. The model was executed 4 times, each during a 7-day period in April and May, and each subsequent survey included new phrasing and/or messaging informed by the previous week’s survey. A total of 917 adults from North Carolina participated in the 4 surveys. Results Survey participants rated messages focused on protecting oneself and others higher than messages focused on norms and fear-based approaches. Pairing behaviors with motivations increased participants’ desire to social distance across all themes and subgroups. For example, adding “Protect your grandmother, your neighbor with cancer, and your best friend with asthma,” to messaging received a 0.9-point higher score than the base message, “Stay 6 feet apart from others when out in public.” Practice Implications Our model to promote social distancing in North Carolina during the COVID-19 pandemic can be used for rapid, iterative message testing during public health emergencies

Observed suppression of ozone formation at extremely high temperatures due to chemical and biophysical feedbacks

Ground level ozone concentrations ([O3]) typically show a direct linear relationship with surface air temperature. Three decades of California measurements provide evidence of a statistically significant change in the ozone-temperature slope (ΔmO3-T) under extremely high temperatures (> 312 K). This ΔmO3-T leads to a plateau or decrease in [O3], reflecting the diminished role of nitrogen oxide sequestration by peroxyacetyl nitrates and reduced biogenic isoprene emissions at high temperatures. Despite inclusion of these processes in global and regional chemistry-climate models, a statistically significant change in ΔmO3-T has not been noted in prior studies. Future climate projections suggest a more frequent and spatially widespread occurrence of this ΔmO3-T response, confounding predictions of extreme ozone events based on the historically observed linear relationship

Scdap/relap5/Mod 3.1 Code Manual: Damage Progression Model Theory. Volume 2

The SCDAP/RELAP5 code has been developed for best estimate transient simulation of light water reactor coolant systems during a severe accident. The code models the coupled behavior of the reactor coolant system, the core, fission products released during a severe accident transient as well as large and small break loss of coolant accidents, operational transients such as anticipated transient without SCRAM, loss of offsite power, loss of feedwater, and loss of flow. A generic modeling approach is used that permits as much of a particular system to be modeled as necessary. Control system and secondary system components are included to permit modeling of plant controls, turbines, condensers, and secondary feedwater conditioning systems. This volume contains detailed descriptions of the severe accident models and correlations. It provides the user with the underlying assumptions and simplifications used to generate and implement the basic equations into the code, so an intelligent assessment of the applicability and accuracy of the resulting calculation can be made

A Comparison of Solid Electrolyte Interphase Formation and Evolution on Highly Oriented Pyrolytic and Disordered Graphite Negative Electrodes in Lithium-Ion Batteries

The presence and stability of solid electrolyte interphase (SEI) on graphitic electrodes is vital to the performance of lithium-ion batteries (LIBs). However, the formation and evolution of SEI remain the least understood area in LIBs due to its dynamic nature, complexity in chemical composition, heterogeneity in morphology, as well as lack of reliable in situ/operando techniques for accurate characterization. In addition, chemical composition and morphology of SEI are not only affected by the choice of electrolyte, but also by the nature of the electrode surface. While introduction of defects into graphitic electrodes has promoted their electrochemical properties, how such structural defects influence SEI formation and evolution remains an open question. Here, utilizing nondestructive operando electrochemical atomic force microscopy (EChem-AFM) the dynamic SEI formation and evolution on a pair of representative graphitic materials with and without defects, namely, highly oriented pyrolytic and disordered graphite electrodes, are systematically monitored and compared. Complementary to the characterization of SEI topographical and mechanical changes during electrochemical cycling by EChem-AFM, chemical analysis and theoretical calculations are conducted to provide mechanistic insights underlying SEI formation and evolution. The results provide guidance to engineer functional SEIs through design of carbon materials with defects for LIBs and beyond

The long-term sustainability of a respiratory culture nudge

Resource-intensive interventions and education are susceptible to a lack of long-term sustainability and regression to the mean. The respiratory culture nudge changed reporting to Commensal Respiratory Flora only: No S. aureus/MRSA or P. aeruginosa. This study demonstrated sustained reduction in broad-spectrum antibiotic duration and long-term sustainability 3 years after implementation
