Disposition of quetiapine in biological specimens from postmortem cases

Quetiapine is a new atypical antipsychotic that was approved in 1997 by the U.S. Food and Drug Administration for the treatment of schizophrenia. It possesses a high affinity for 5-HT2 receptors and a low affinity for D1 and D2 dopamine receptors. Because quetiapine has only been released recently to the U.S. market, little information exists regarding therapeutic, toxic, and lethal concentrations. This study reports the detection of quetiapine in 13 postmortem cases. Following a basic liquid-liquid extraction, quetiapine was identified and quantitated by capillary gas chromatography with nitrogen phosphorus detection. Confirmation was accomplished by full scan electron impact gas chromatography/mass spectrometry. Heart blood quetiapine concentrations ranged from 0.07 to 18.37 mg/L (N = 12, mean +/- SD = 3.42 +/- 5.67, median 0.62) and femoral blood concentrations ranged from 0.06 to 19.25 mg/L (N = 10. mean +/- SD = 3.89 +/- 6.12, median 0.81). The average heart blood/femoral blood ratio was 1.31 (range 0.55 to 2.57, N = 10). Urine, bile, and gastric contents were assayed in all cases in which they were submitted. In three cases, the cause of death was determined to be quetiapine toxicity. In these cases heart blood concentrations ranged from 0.72 to 18.37 mg/L (N = 3). These data may provide a basis for establishing levels associated with quetiapine toxicity as well as therapeutic concentrations in postmortem specimens.     

Postmortem tissue distribution of olanzapine and citalopram in a drug intoxication

A 40-year-old white male was found dead in bed in a group home for mentally ill adults. The decedent had been diagnosed a paranoid schizophrenic. An autopsy was performed at the Office of the Cuyahoga County Coroner in Cleveland, Ohio. Toxicological testing detected olanzapine and citalopram in post mortem specimens. Multiple fluids and tissues were assayed by liquid-liquid extraction followed by gas chromatography with nitrogen phosphorus detection, and qualitative confirmation by electron impact gas chromatography/mass spectrometry. Drug concentrations [olanzapine: citalopram; mg/L or mg/Kg] determined in this case are the highest reported to date involving these drugs- 1.38:3.35 heart blood, 1.11:1.65 femoral blood, 60.24:32.43 urine, 6.47:10:71 liver, and 38.36:49.16 lung, respectively. Drug concentrations in tissues were found to be the highest in lung for both drugs and lowest in the heart. Citalopram but not olanzapine was detected in bone. The cause of death was ruled acute intoxication by the combined effects of olanzapine and citalopram and the manner, accident.

Digital government units: what are they,and what do they mean for digital era public management renewal?

Abstract

From 2011 onward, Digital Government Units (DGUs) have quickly emerged as a preferred solution for tackling the over-cost and under-performing digital services and lagging digital transformation agendas plaguing today’s governments. This article kickstarts a much-needed research agenda on this emerging trend, which has to date largely been ignored by public management scholars. DGUs exist at the center of the state, and adopt a shared orthodoxy, favoring agile, user-centric design, pluralistic procurement, data-driven decision making, horizontal ‘platform’ based solutions and a ‘delivery-first’ ethos. However, DGUs are differentiated in practice by their governance structures and resources, adding notable complexity to this recent machinery of government phenomenon. The article details the similarities and differences across six of the first DGUs introduced and highlights issues that researchers should address when assessing DGUs as an increasingly preferred instrument of digital era public sector renewal. This includes: their mixed record of success thus far; the risks of top-down reform efforts; external threats to DGUs’ sustainability; and accountability dilemmas accompanying digital government reforms.     

Legislating School Crisis Response: Good Policy or Just Good Politics?

Over the past decade, a growing number of schools have responded to students' safety and mental health needs following campus violence and other crises. More recently, policymakers have joined this trend, proposing legislation requiring schools to establish crisis response programs. This paper provides an overview of crisis response initiatives implemented by school districts following traumatic events, including school violence. It then examines recent state legislation and other policies, followed by a discussion of the advisability of such mandates, given the scant research and evaluation of school crisis response to date.
