The opioid epidemic has affected the United States (US) for decades with fentanyl and its analogs accounting for a recent surge in morbidity and mortality. Currently, there is a relative lack of information characterizing fentanyl-related fatalities specifically in the Southern US. A retrospective study was conducted to examine all postmortem fentanyl-related drug toxicities in Travis County, Texas, encompassing Austin (one of the fastest-growing cities in the US), from 2020 to 2022. Fentanyl contributed to 2.6% and 12.2% of deaths submitted for toxicology between 2020 and 2022, respectively, representing a 375% increase in fentanyl-related deaths over this 3-year period (n = 517). Fentanyl-related fatalities primarily occurred in males in their mid-30s. Fentanyl and norfentanyl concentrations ranged from 0.58 to 320 ng/mL and 0.53 to 140 ng/mL with mean (median) concentrations of 17.2 ± 25.0 (11.0) and 5.6 ± 10.9 (2.9) ng/mL, respectively. Polydrug use was present in 88% of cases, with methamphetamine (or other amphetamines) (25%), benzodiazepines (21%), and cocaine (17%) representing the most frequently identified concurrent substances. Co-positivity rates of various drugs and drug classes widely varied over time. Scene investigations reported illicit powder(s) (n = 141) and/or illicit pill(s) (n = 154) in 48% (n = 247) of fentanyl-related deaths. Illicit oxycodone (44%, n = 67) and illicit “Xanax” (38%, n = 59) pills were frequently reported on scene; however, toxicology only identified oxycodone and alprazolam in 2 and 24 of these cases, respectively. The results of this study provide a better understanding of the fentanyl epidemic in this region creating an opportunity to promote increased awareness, shift focus to harm reduction, and aid in minimizing public health risks. 相似文献

This research note presents EPAC 2017, a dataset resulting from the second round of an expert survey on ethnonationalism in party competition. EPAC provides cross-sectional data on the positions of (ethno-) national and mainstream parties on an ethnonational (also often referred to as ‘territorial’ or ‘centre-periphery’) dimension, as well as other important dimensions of political competition. The 2017 edition covers 222 political parties in 22 multinational European countries. The research note presents the main survey items and performs a series of validity and reliability tests on the data. Results show that EPAC 2017 provides valid and reliable measures of party positions on an ethnonational dimension. A short analysis of party system changes in Spain and Bosnia and Herzegovina illustrates the opportunities of combining the 2011 and 2017 editions. The combined dataset allows studying the mobilization of the centre-periphery cleavage in party competition across Eastern and Western Europe and over time. 相似文献

This article offers an explanation for the theoretical underdevelopment of Public Administration. It argues that Public Administration studies the relations among elements of the administrative state and between the administrative state and its environment dissociated from time. The ahistorical orientation of the discipline has drastically reduced its capacity for theory building. 相似文献
