Abstract
The simultaneous abuse of alcohol-cocaine is known to cause stronger and more unpredictable cellular damage in the liver, heart, and brain. However, the mechanistic crosstalk between cocaine and alcohol in liver injury remains unclear. The findings revealed cocaine-induced liver injury and inflammation in both marmosets and mice. Of note, co-administration of cocaine and ethanol in mice causes more severe liver damage than individual treatment. The metabolomic analysis confirmed that hippuric acid (HA) is the most abundant metabolite in marmoset serum after cocaine consumption and that is formed in primary marmoset hepatocytes. HA, a metabolite of cocaine, increases mitochondrial DNA leakage and subsequently increases the production of proinflammatory factors via STING signaling in Kupffer cells (KCs). In addition, conditioned media of cocaine-treated KC induced hepatocellular necrosis via alcohol-induced TNFR1. Finally, disruption of STING signaling in vivo ameliorated co-administration of alcohol- and cocaine-induced liver damage and inflammation. These findings postulate intervention of HA-STING-TNFR1 axis as a novel strategy for treatment of alcohol- and cocaine-induced excessive liver damage.

Abstract
BACKGROUND AND AIMS The number of xylazine-involved overdose deaths tremendously increased from 2019 onwards in the US. This is due to the "tranq-dope" trend consisting in mixing opioids with the sedative to reduce drug manufacturing costs and enhance their effects. In this study, we report the first fatality involving xylazine-adulterated heroin in the EU. MATERIALS AND METHODS The subject was a 33-year-old Caucasian male with a documented history of drug abuse who was found dead in a public area with puncture marks at the elbow. Peripheral blood and urine were collected at the autopsy and analyzed by liquid chromatography-high-resolution tandem mass spectrometry (LC-HRMS/MS) after protein precipitation. RESULTS 6-Monoacetylmorphine, total/free morphine, and codeine blood concentrations of 20.3, 236/105, and 38.3 ng/mL, respectively, indicated recent heroin consumption. Methadone blood concentration was below 10 ng/mL. Alprazolam, nordiazepam, and flurazepam blood concentrations were 23.9, 61.4, and 55.0 ng/mL, respectively. Benzoylecgonine blood concentration was below 5 ng/mL. Xylazine blood and urine concentrations were 105 and 72.6 ng/mL, respectively. CONCLUSION The combination of central nervous system depressants, i.e., opioids, benzodiazepines, and xylazine, was the principal cause of death by cardiorespiratory failure. The case was promptly reported to the UE Early Warning System on drugs.

Abstract
Available literature demonstrates that methadone is prone to moderate postmortem redistribution, but subject to high interindividual variability in the central to peripheral blood concentration ratios (C/P). In this case series, 10 cases of chronic methadone users displaying C/P < 1 (range 0.26-0.82) are described. Femoral, cardiac and ante-mortem blood concentrations of methadone and its metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) are reported for all cases, as well as sex, age, case history, results of the pathological investigation, other toxicological findings and cause and manner of death. EDDP blood concentrations, similar in both central and peripheral blood, as well as antemortem blood concentration results in Case 4, demonstrate that this atypical C/P < 1 finding is attributable to postmortem changes and not analytical or pre-analytical artifacts. Case 4 is a particularly instructive example, with femoral blood concentration (966 ng/mL) approximately twice as high as cardiac blood (499 ng/mL) and ante-mortem blood (418 ng/mL, collected 38 min prior to death)-clearly demonstrating that cardiac blood methadone concentration is more representative of the antemortem blood concentration in this case. In Case 4 and four others, toxicological interpretation based on femoral blood concentration alone would have been misleading. Based on these results and evidence from the literature, it is hypothesized that methadone bioaccumulates in the tissues of chronic users and redistributes from thigh tissues into femoral blood, increasing the concentration postmortem. This case series highlights how femoral blood is not always preserved from postmortem changes and that the analysis of multiple blood sources is necessary to avoid a misleading toxicological interpretation-particularly for cases of chronic methadone users.

Abstract
This study aimed to compare the concentration of various xenobiotics in both cerebrospinal fluid (CSF) and blood. We examined 175 autopsy cases covering a wide range of ages, causes of death, and drug ingestion histories, with cerebrospinal fluid and blood samples available for toxicological testing. Analytes studied included opioids, benzodiazepines, antidepressants, antipsychotics, and illicit substances such as cannabinoids, stimulants and new psychoactive substances, including synthetic cathinones and synthetic cannabinoids. We found that concentrations in CSF were generally lower than in blood. A significant correlation was observed between drug concentrations in CSF and blood for many analytes (p < 0.05). However, the strength and direction of the correlation varied considerably depending on the physicochemical properties of the drugs, suggesting that a 'one size fits all' model may not be applicable. The results indicate that cerebrospinal fluid (CSF) can be used to detect a variety of xenobiotics, particularly amphetamines, synthetic cathinones and synthetic cannabinoids, in cases where conventional biological materials are not available. Additionally, using the results obtained in the future can lead to a better understanding of pharmacokinetic processes and the effect of post-mortem redistribution. Further research is needed to refine our understanding of these relationships.

Abstract
Cocaine, methamphetamine, ectasy (3,4-methylenedioxy amphetamine (MDMA)) and ketamine are among the most consumed drugs worldwide causing cognitive, oxidative stress and cardiovascular problems in humans. Residue levels of these drugs and their transformation products may still enter the aquatic environment, where concentrations up to hundreds of ng/L have been measured. In the present work we tested the hypothesis that psychotropic effects and the mode of action of these drugs in D. magna cognitive, oxidative stress and cardiovascular responses are equivalent to those reported in humans and other vertebrate models. Accordingly we expose D. magna juveniles to pharmacological and environmental relevant concentrations. The study was complemented with the measurement of the main neurotransmitters involved in the known mechanisms of action of these drugs in mammals and physiological relevant amino acids. Behavioural cognitive patters clearly differentiate the 3 psychostimulant drugs (methamphetamine, cocaine, MDMA) from the dissociative one ketamine. Psychostimulant drugs at pharmacological doses (10-200 μM), increased basal locomotion activities and responses to light, and decreased habituation to it. Ketamine only increased habituation to light. The four drugs enhanced the production of reactive oxygen species in a concentration related manner, and at moderate concentrations (10-60 μM) increased heartbeats, diminishing them at high doses (200 μM). In chronic exposures to environmental low concentrations (10-1000 ng/L) the four drugs did not affect any of the behavioural responses measured but methamphetamine and cocaine inhibited reproduction at 10 ng/L. Observed effects on neurotransmitters and related metabolites were in concern with reported responses in mammalian and other vertebrate models: cocaine and MDMA enhanced dopamine and serotonin levels, respectively, methamphetamine and MDMA decreased dopamine and octopamine, and all but MDMA decreased 3 MT levels. Drug effects on the concentration of up to 10 amino acids evidence disruptive effects on neurotransmitter synthesis, the urea cycle, lipid metabolism and cardiac function.

Abstract
The barbiturate drug pentobarbital is commonly used by veterinarians for the euthanasia of domestic animals. During the veterinary forensic autopsy, it is sometimes necessary to determine whether the animal was chemically euthanized with pentobarbital. The use of a human immunochromatographic test for barbiturate screening utilizing dog or cat urine has been previously validated; however, the use of alternative matrices for this purpose is yet to be explored when urine is not available. Postmortem heart, liver, spleen, skeletal muscle, blood and/or urine samples from 20 dogs and 26 cats with a reported chemical euthanasia status were processed using two different methods, bead homogenization and sonication, and screened for barbiturates using a human immunochromatographic test. There was 100% agreement of the immunochromatographic test results using the sonication method with the reported euthanasia status of both dogs and cats. Using the bead homogenization method, agreement with the reported euthanasia status was 93.3% and 96.7% for dogs and cats, respectively, due to invalid test results from four dog and two cat samples. A subset of liver samples (10 canine and 10 feline) was analyzed via gas chromatography-mass spectrometry, and there was 100% agreement between the immunochromatographic test results and gas chromatography-mass spectrometry results for both cats and dogs. Overall, our results support the use of a variety of alternative matrices for barbiturate screening in cats and dogs.

Abstract
ostmortem redistribution (PMR), a well-known phenomenon in forensic toxicology, can result in substantial changes in drug concentrations after death, depending on the chemical characteristics of the drug, blood collection site, storage conditions of the body and postmortem interval (PMI). Limited PMR data are available for ∆9-tetrahydrocannabinol (THC), the primary psychoactive component in Cannabis sativa. PMR was evaluated after controlled cannabis inhalation via a smoking machine and exposure chamber in New Zealand white rabbits. Necropsies were performed on five control rabbits immediately after euthanasia, whereas 27 others were stored at room temperature (21°C) or refrigerated conditions (4°C) until necropsy at 2, 6, 16, 24 or 36 h after death. THC and its Phase I and glucuronidated Phase II metabolites were quantified in blood, vitreous humor, urine, bile and tissues by liquid chromatography-tandem mass spectrometry (LC-MS-MS). Under refrigerated temperature, heart blood THC concentrations significantly increased at PMI 2 h in rabbits, whereas peripheral blood THC concentrations showed a significant increase at PMI 16 h. Central:peripheral blood and liver:peripheral blood ratios for THC ranged from 0.13 to 4.1 and 0.28 to 8.9, respectively. Lung revealed the highest THC concentrations, while brain and liver exhibited the most stable THC concentrations over time. This report contributes much needed data to our understanding of postmortem THC behavior and can aid toxicologists in the interpretation of THC concentrations in medicolegal death investigations.

Abstract
The assessment of human postmortem concentrations of Δ9-THC (THC) and its metabolites, 11-nor-9-carboxy-THC (THCCOOH) and 11-hydroxy-THC (11-OH-THC), is routinely performed in forensic toxicology laboratories. However, the literature on cannabinoids postmortem redistribution (PMR) is scarce and highlights their complex postmortem changes. This study aims to investigate the postmortem behavior of THC and its metabolites in order to provide practitioners with potential indicators of PMR. To do so, antemortem and postmortem cases positive for cannabinoids were compiled in a database. Its analysis shows significantly higher THC concentrations in postmortem blood than in antemortem blood. Antemortem and postmortem blood also present significantly different profiles for their THC to THCCOOH ratios. Whereas antemortem blood generally shows THCCOOH concentrations higher or equal to THC, several postmortem cases show the opposite, with THC concentrations higher than THCCOOH. While occurrence of postmortem redistribution (PMR) is difficult to measure directly, an evaluation was performed using the central to peripheral (C/P) blood concentrations ratio as a proxy. With a C/P significantly lower than 1.0 for THC and significantly higher than 1.0 for THCCOOH, the PMR hypothesis is supported for both compounds, with redistribution towards peripheral blood for THC and towards central blood for THCCOOH. On the other hand, 11-OH-THC does not show a C/P significantly different than 1.0, suggesting the absence of PMR. Influence of body mass index, conservation state and postmortem interval on C/P was statistically analyzed and no significant impact was observed. To compare and contrast C/P observed in the database with those published in the literature, a meta-analysis was performed using a median of median (MM) model. THC PMR towards peripheral blood is supported by a global estimate of 0.81 (CI95%: 0.51 to 1.2). Redistribution towards femoral blood appears to be stronger than towards iliac blood; indeed, the median estimate of C/P decreases to 0.64 (CI95%: 0.40 to 1.1) when studies with iliac blood were removed from the meta-analysis. THCCOOH PMR towards central blood is supported by a C/P median estimate of 1.3 (CI95%: 0.97 to 1.6). THC PMR can be suspected when these indicators are observed (i) high THC blood concentration (>50 ng/mL), (ii) THC C/P lower than 1.0 (iii) blood THC/THCCOOH concentration ratios greater than 1.0 and (iv) non-detectability of THCCOOH in urine. In postmortem samples, many factors may contribute to the overestimation of THC concentration, therefore a careful interpretation is required, relying on both central and peripheral blood samples.

Abstract
INTRODUCTION The primary objective of postmortem forensic toxicology is to determine if toxicological substances detected in bodily material of victims have contributed to the death of the victim. Interpretation of postmortem drug concentrations is hindered by the fact that time and site dependent variations in postmortem drug concentrations occur, as a result of postmortem redistribution (PMR). An often-used marker for the occurrence of PMR, is the cardiac blood concentration/peripheral blood concentration ratio (C/P ratio) of a drug. In this study, we investigated the relationship between 13 variables and the C/P ratios of amphetamines and benzodiazepines. METHOD Toxicological results of all postmortem cases that were positive for amphetamines (amphetamine, MDMA, MDA) and/or benzodiazepines (diazepam, desmethyldiazepam, temazepam, oxazepam, midazolam, α-hydroxymidazolam) investigated by the Netherlands Forensic Institute between January 1 2010 and July 31 2020 were reviewed. A total of 112 amphetamine positive cases (224 paired specimen) and 179 benzodiazepine positive cases (358 paired specimen) were selected. The C/P ratios were determined for all selected cases. Ratios were compared between subgroups by performing either a Mann-Whitney U test or a Kruskal-Wallis test followed by post-hoc Mann-Whitney U test. RESULTS After dividing cases in quartiles based on their amphetamine concentration in femoral blood, the amphetamine C/P ratio was significantly lower in cases with a high amphetamine concentration (quartile 4) compared to cases with a low amphetamine concentration (quartiles 1 and 2) with median C/P ratios of 1.6, 2.4 and 2.2, respectively (p-value<0.001 and p-value=0.001, respectively). The MDA C/P ratio was significantly higher in cases where trauma was the cause of death compared to cases where intoxication was the cause of death with median C/P ratios of 3.3 and 1.6, respectively (p-value<0.001). The MDA C/P ratio was also significantly lower in cases where resuscitation was attempted compared to cases where no resuscitation was attempted with median C/P ratios of 1.6 and 2.4, respectively (p-value=0.003). However, a significant dependency between the variables cause of death and attempted resuscitation was observed. No significant differences in benzodiazepine C/P ratios were observed between subgroups of any of the investigated variables. However, the low p-value of BMI suggests a potential difference in midazolam C/P ratio between BMI subgroups (p-value=0.027). CONCLUSION When interpreting postmortem toxicological results, it might prove useful to take the above-mentioned variables into account.

JAMA Psychiatry 2023; 80:1121-1130. [PMID: 37494023 PMCID: PMC10372754 DOI: 10.1001/jamapsychiatry.2023.2289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 05/15/2023] [Indexed: 07/27/2023]
Abstract
Importance Determining the association between drug use and suicide is complicated but can help to inform targeted suicide prevention strategies. Objective To examine the substances prevalent in poisoning- and nonpoisoning-related suicides in Australia. Design, Setting, and Participants This was a multiple-year, cross-sectional study of suicides from July 2013 to October 2019 in Australia with toxicology data available in a national coronial database. The cause of death was classified as poisoning related if any type of poisoning was determined by the coroner to contribute to the cause of death. Prevalence ratios (PRs) were calculated to compare substance detection in poisoning- vs nonpoisoning-related suicides. Data were analyzed from October 2021 to April 2023. Exposures All substances detected in decedents at the time of death according to toxicology reports were recorded. Main Outcome(s) and Measure(s) The most common individual substances and substance classes were identified. From these, blood concentrations of substances of interest were analyzed, and the most commonly occurring combinations of substance classes were listed. Results Toxicology was performed on 13 664 suicide decedents (median [IQR] age, 44 [31-57] years; 10 350 male [76%]). From these, 3397 (25%) were poisoning-related suicides (median [IQR] age, 50 [38-63] years; 2124 male [63%]). The remainder were classified as nonpoisoning-related suicides (median [IQR] age, 42 [29-55] years; 8226 male [80%]). PRs for common medicine classes being detected in poisoning-related suicides compared with nonpoisoning-related suicides were as follows: antidepressants (PR, 1.63; 95% CI, 1.54-1.73), benzodiazepines (PR, 2.01; 95% CI, 1.90-2.13), nonopioid analgesics/anti-inflammatory drugs (PR, 1.88; 95% CI, 1.78-2.00), and opioids (PR, 2.72; 95% CI, 2.58-2.87). Alcohol (as ethanol ≥0.03 g/100 mL) was almost equally prevalent in poisoning- and nonpoisoning-related deaths (PR, 1.07; 95% CI, 1.01-1.14), whereas amphetamines (PR, 0.68; 95% CI, 0.61-0.77) and cannabinoids (PR, 0.67; 95% CI, 0.60-0.74) were detected more often in nonpoisoning-related suicides. Combinations of multiple sedative agents in poisoning-related suicides were common. Conclusions and Relevance Both poisoning- and nonpoisoning-related suicide deaths featured a high prevalence of psychotropic medicines or potential intoxication, which suggests the association of suicide with poor mental health and substance misuse. Findings suggest that substances with a high involvement in poisoning-related suicides should be prescribed cautiously, including antidepressants that are toxic in overdose, sedatives, opioids, and potentially lethal combinations.

[PMID: 37494426 DOI: 10.1093/jat/bkad046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 07/07/2023] [Accepted: 07/24/2023] [Indexed: 07/28/2023] Open
Abstract
Due to the high prevalence of cannabinoids in forensic toxicology analysis, it is crucial to have an efficient method that allows the use of a small sample amount and that requires a minimal sample preparation for the determination and quantification of low concentrations. A simple, highly selective and high throughput liquid chromatography-tandem mass spectrometry methodology (LC-MS-MS-MS3) was developed for the determination and quantification of ∆9-tetrahydrocannabinol (THC), 11-hydroxy-∆9- tetrahydrocannabinol (THC-OH) and 11-nor-9-carboxy-∆9-tetrahydrocannabinol (THC-COOH) in blood samples. Chromatographic analysis of THC, THC-OH and THC-COOH and their deuterated internal standards was preceded by protein precipitation (PPT) of 0.1 mL of blood samples with acetonitrile. Chromatographic separation was achieved by use of an Acquity UPLC® HHS T3 (100 mm × 2.1 mm i.d., 1.8 μm) reversed-phase column, using a gradient elution of 2 mM aqueous ammonium formate, 0.1% formic acid and methanol at a flow rate of 0.4 mL/min, with a run time of 10 min. For the MS-MS-MS3 analysis, a SCIEX QTRAP® 6500+ triple quadrupole linear ion trap mass spectrometer was used via electrospray ionization (ESI), operated in multiple reaction monitoring (MRM) and linear ion trap mode (MS3). The method was validated in accordance with internationally accepted criteria and guidelines, and proved to be selective and linear between 0.5 and 100 ng/mL (r2 > 0.995). The lower limits of quantification (LLOQ) corresponded to the lowest concentrations used for the calibration curves. The coefficients of variation obtained for accuracy and precision were <15%. The mean recoveries were between 88.0% and 117.2% for the studied concentration levels (1 ng/mL, 5 ng/mL and 50 ng/mL). No significant interfering compounds, matrix effects or carryover were observed. The validated method provides a sensitive, efficient and robust procedure for the quantification of cannabinoids in blood, using LC-MS-MS-MS3 and a sample volume of 0.1 mL. This work is also a proof of concept for using LC-MS3 technique to determine drugs in biological samples.

Abstract
This scoping review intends to identify the most used analytical methods and biological samples in the post-mortem forensic toxicological analysis of cocaine and its metabolites. A scoping review was performed based on the question "What are the analytical methods and types of biological samples most frequently used to identify and quantify cocaine in post-mortem forensic toxicology?" The studies were selected from five databases and, after exclusions, the data were tabulated, analyzed, and reported. Twenty-one articles published between 2012 and 2022 were filtered from five different databases to be studied. The collected data indicate that the most used biological samples were blood and hair. The most used sample preparation technique was solid phase extraction, while the most mentioned chromatography method was liquid chromatography with mass spectrometry. This review presents and discusses the state of the art regarding methods for the detection sensitivity spectrum, why limits of quantification are so important for these methods, and what are the most suitable biological samples to be utilized in each case. Cocaine and metabolites are important in forensic toxicologic post-mortem analysis. However, there is little concern in the development of miniaturized and automated sample preparation in this field. Besides, there is not enough understanding of post-mortem redistribution, tolerance, drug-drug interactions, and pre-existing medical conditions.

[PMID: 36516237 DOI: 10.1093/jat/bkac104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 11/16/2022] [Accepted: 12/13/2022] [Indexed: 12/15/2022] Open
Abstract
New psychoactive substances (NPSs) still represent an issue of great concern worldwide despite efforts made by national and international control systems to limit the spread of these substances. Alpha-pyrrolidinohexanophenone (α-PHP) is a fairly recent synthetic cathinone (the second largest group of monitored substances in Europe) with only a few published studies on the substance. Though there is a low incidence of NPS consumption in Portugal, a recent increase in apprehensions and detections in biological matrices of the substance was verified. An analytical methodology was developed and validated for determining and quantitating α-PHP in blood. Solid-phase extraction was employed for sample preparation (500 μL), which was further analyzed by gas chromatography--mass spectrometry-electron ionization in single-ion monitoring mode with cocaine-d3 as the internal standard. Method validation followed the guidelines of the American National Standards Institute/AAFS Standards Board (ANSI/ASB Standard 036). The procedure was linear between 10 and 1,000 ng/mL, with determination coefficients (r2) higher than 0.999. Carryover was not observed. A limit of detection of 5 ng/mL and a limit of quantitation of 10 ng/mL were achieved. Intraday and intermediate precision and bias assessment showed satisfactory results (coefficient of variation <17.7%; bias <11.6%), and extraction efficiency ranged from 98.5% to 103.3%. The stability of the substance was considered acceptable for at least 6 h at room temperature, 48 h in the autosampler and 21 days after five freeze/thaw cycles. The developed methodology was applied to 15 real samples from the Laboratory of Chemistry and Forensic Toxicology, Centre Branch of the National Institute of Legal Medicine and Forensic Sciences, Portugal, with drug concentrations ranging from 15 to 227 ng/mL. Available information for each case is also detailed in the present article.

Abstract
In this paper, we present the results of toxicological analyses of preserved brain tissue and bone samples from the remains of the seventeenth century patients of the Ospedale Maggiore, the main hospital in Milan and one of the most innovative hospitals in Europe from the Renaissance period. Beneath it, the crypt functioned as the burial place for the deceased of the hospital. In this multidisciplinary study of the remains, toxicological analyses in particular were performed with HPLC-MS/MS on different biological samples from nine individuals. Anthropological, paleopathological, histological, radiological examinations and radiocarbon dating were also carried out. As a result, archeotoxicological analyses revealed the presence of codeine, morphine, noscapine and papaverine, derived from Papaver somniferum, a plant present in the hospital pharmacopeia used as a narcotic, analgesic, astringent, coagulant, and antitussive agent. Such analyses have shed light on the pharmacological therapies administered to the patients near the time of death and have implemented our knowledge of medical treatment and drug administration in the 1600's.

Abstract
Microbial diversity's potential has been investigated in medical and therapeutic studies throughout the last few decades. However, its usage in forensics is increasing due to its effectiveness in circumstances when traditional approaches fail to provide a decisive opinion or are insufficient in forming a concrete opinion. The application of human microbiome may serve in detecting the type of stains of saliva and vaginal fluid, as well as in attributing the stains to the individual. Similarly, the microbiome makeup of a soil sample may be utilised to establish geographic origin or to associate humans, animals, or things with a specific area, additionally microorganisms influence the decay process which may be used in depicting the Time Since death. Further in detecting the traces of the amount and concentration of alcohol, narcotics, and other forensically relevant compounds in human body or visceral tissues as they also affect the microbial community within human body. Beside these, there is much more scope of microbiomes to be explored in terms of forensic investigation, this review focuses on multidimensional approaches to human microbiomes from a forensic standpoint, implying the potential of microbiomes as an emerging tool for forensic investigations such as individual variability via skin microbiomes, reconstructing crime scene, and linking evidence to individual.

Abstract
The best evidence provided in the literature worldwide suggests the importance of harmonizing the investigation in drug-related fatalities. In this study, the application of a multidisciplinary approach in eight cases of drug-related deaths is presented. Although death scene findings could be highly suggestive of drug intoxication, external examination and toxicological screening test alone are insufficient. There are several variables, and it is not always easy to give the proper interpretation of the drug detection. A complete autopsy is necessary to correctly complete organ and tissues sampling for further histological and toxicological studies and obtain body fluids. The use of peripheral blood is recommended to avoid artifacts. The collection of many specimens is warranted to get more responses. The sampling aims to provide a picture of the distribution of the substance in the body. The sample and the selection of the drugs and the matrices to investigate are case-dependent. The presented diagnostic algorithm provides the coroner with all the elements to investigate drug-related deaths and cooperate with toxicologists. Toxicological forensic diagnosis is still extremely heterogeneous in regional and national contexts. Funding for method development, research, networking, facilities, and technologies improvement is mandatory to standardize the toxicological investigation.

Abstract
INTRODUCTION Several forms of cannabinoids are currently being used to manage nausea and vomiting (N/V). Emerging cases of refractory N/V associated with chronic cannabis use among adults and older patients have been reported named cannabis hyperemesis syndrome (CHS). CHS is a condition that leads to repeated and severe N/V in long-term users of cannabinoids. OBJECTIVE The aim of this study was to outline current treatments for the management of CHS. METHODS A systematic review was conducted using PubMed, Ovid MEDLINE, Cochrane Central, EMBASE, and Google Scholar. Databases were used to search for articles on CHS published from January 2009 to June 2021, yielding 225 results of which 17 were deemed relevant and underwent review by 2 separate reviewers. RESULTS The duration of cannabis administration ranged between 6 months to 11 years may precipitate symptoms of CHS. The Rome IV diagnostic criteria of CHS require cannabinoid use and persistence of N/V symptoms for at least the past 6 months. Cannabis cessation is noted to be the most successful management, but other treatments also demonstrated symptom relief; these include hot water hydrotherapy, topical capsaicin cream, haloperidol, droperidol, benzodiazepines, propranolol, and aprepitant administration. CONCLUSION More research on CHS is needed to enhance knowledge translation, education, and create awareness in the medical community on the side effects of cannabinoids and to propose the best treatment options.

Distribution of tetrahydrocannabinol and cannabidiol in several different postmortem matrices. Forensic Sci Int 2021; 329:111082. [PMID: 34775328 DOI: 10.1016/j.forsciint.2021.111082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 10/15/2021] [Accepted: 10/22/2021] [Indexed: 11/21/2022]
Abstract
Cannabis is the most widely used illicit substance worldwide. A limited number of studies have investigated whether tetrahydrocannabinol (THC) and cannabidiol (CBD) can be detected in other postmortem matrices than blood and urine. The aim of this study was to investigate the distribution of THC and CBD in several different postmortem matrices. Concentrations in peripheral blood were compared to those in cardiac blood, pericardial fluid, psoas muscle, vastus lateralis muscle, and vitreous humor. A total of 39 postmortem forensic autopsy cases were included. THC and CBD were analyzed using gas chromatography-mass spectrometry. We were able to detect both THC and CBD in most of the analyzed matrices. For vitreous humor, however, only approximately 50% of the cases were available for analysis, and only two were found to be positive. Median concentrations in peripheral blood were 0.0040 (0.00042-0.056) mg/L for THC and 0.0013 (0-0.023) mg/L for CBD. The concentration ratios between pericardial fluid and cardiac blood compared to peripheral blood were< 1 for both THC and CBD for the majority of the cases. For THC, a median ratio of 0.60 (0.063-7.2) and 0.65 (0.068-4.8) were found for pericardial fluid and cardiac blood, respectively, compared to peripheral blood, whereas for CBD the corresponding median ratios were 0.40 (0.010-1.9) and 0.80 (0.017-2.4). The THC concentrations in psoas muscle and vastus lateralis muscle were high compared to those in peripheral blood in several cases, and large variations in the muscles to peripheral blood concentration ratios were seen. This was also the case for CBD. Our study shows that THC and CBD can be detected in postmortem matrices other than peripheral blood, and results from other matrices might provide important information in forensic cases where peripheral blood is not available. However, vitreous humor was not suitable for detecting neither THC nor CBD.

Homicidal poisoning series in a nursing home: retrospective toxicological investigations in bone marrow and hair. Int J Legal Med 2021; 136:123-131. [PMID: 34591183 DOI: 10.1007/s00414-021-02703-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 09/13/2021] [Indexed: 10/20/2022]
Abstract
Homicidal poisonings remain rare and can be difficult to detect, especially in the elderly or in medical settings. In this atypical poisoning series, a young nursing assistant purposely poisoned thirteen residents of a nursing home and killed ten of them. The medications used were a mix of psychotropic medications (cyamemazine, loxapine, tiapride, risperidone, and mirtazapine), under liquid formulation, which were inducing malaise and coma. The forensic investigation included analysis of blood, urine, hair, and bone marrow and exhumations of seven corpses up to 3 years after the inhumation. Hair collected from a hairbrush of a cremated victim have been analyzed. Bone marrow sample preparation was based on a liquid/liquid triple extraction. Hair were incubated after decontamination overnight at 55 °C in methanol. Segmentation was possible for seven samples, except for delayed exhumation samples (n = 4) and hairbrush hair sample (n = 1). The extracts were then analyzed using gas chromatography coupled with mass spectrometry (GC-MS) for unknown screening and using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) for a targeted screening and quantification. Screenings revealed the presence of the same mix of psychotropic medications. Cyamemazine, mirtazapine, loxapine, tiapride, and risperidone hair concentrations were 6-17,458 pg/mg, 74-1271 pg/mg, 9-1346 pg/mg, 13-148 pg/mg, and 3-5 pg/mg, respectively. Cyamemazine bone marrow concentrations were 229 and 681 ng/g and 152-717 ng/mL in blood. Patients' medications were also identified and quantified. This poisoning series provide analytical data that could support subsequent toxicological result interpretation in similar forensic cases.

Abstract
Disposable single-use electrochemical sensor strips were used for quantitative detection of small concentrations of morphine in untreated capillary whole blood. Single-walled carbon nanotube (SWCNT) networks were fabricated on a polymer substrate to produce flexible, reproducible sensor strips with integrated reference and counter electrodes, compatible with industrial-scale processes. A thin Nafion coating was used on top of the sensors to enable direct electrochemical detection in whole blood. These sensors were shown to detect clinically relevant concentrations of morphine both in buffer and in whole blood samples. Small 38 μL finger-prick blood samples were spiked with 2 μL of morphine solution of several concentrations and measured without precipitation of proteins or any other further pretreatment. A linear range of 0.5-10 μM was achieved in both matrices and a detection limit of 0.48 μM in buffer. In addition, to demonstrate the applicability of the sensor in a point-of-care device, single-determination measurements were done with capillary samples from three subjects. An average recovery of 60% was found, suggesting that the sensor only measures the free, unbound fraction of the drug. An interference study with other opioids and possible interferents showed the selectivity of the sensor. This study clearly indicates that these Nafion/SWCNT sensor strips show great promise as a point-of-care rapid test for morphine in blood.

Abstract
In the past dozen years, the cases of tramadol intoxication have become frequent in many countries. Most previous studies focused on tramadol's pharmacology, such as pharmacokinetics, pharmacodynamics and pharmacogenetics. However, the dynamic distribution and postmortem redistribution (PMR) of tramadol remain unclear. Our study aimed to investigate these two issues systematically in various specimens of 216 poisoned male rats. A validated gas chromatography-mass spectrometry method was used in this study to measure the concentrations of tramadol. In the first part, 66 tramadol poisoned rats were sacrificed at 11 different time points and their organs were collected separately for the study of tramadol's dynamic distribution, which made it feasible to investigate its PMR later on. The results of this part showed that tramadol's concentrations varied according to the organ and time, and peaked 2 h after intragastric administration in the specimens of liver, kidney, spleen, lung, brain and heart-blood (except stomach and heart). Based on the results of the first part, the concentration of tramadol peaked 2 h in most tissues. Therefore, this time point was used for the study of tramadol's PMR. In the second part, the remaining 150 rats were sacrificed 2 h after intragastric administration of tramadol, and the carcasses were stored under three different conditions (-20, 4 and 20°C). The autopsy was carried out at eight different time points and their organs were collected separately. The results of this part showed that under storage temperatures of -20 and 4°C, the concentrations of tramadol in individual organs showed no significant changes at different time points whereas under a storage temperature of 20°C, the concentrations in certain organs (liver, kidney, spleen, lung, brain and heart-blood) increased significantly at the last few time points. PMR of tramadol was therefore confirmed. The process of PMR of tramadol could be slowed or stopped at lower storage temperatures (-20 or 4°C), which is significant in cases of suspected tramadol poisoning.

Abstract
A procedure based on gas chromatography-mass spectrometry was developed for the analysis of benzodiazepines (nordiazepam, oxazepam, lormetazepam, lorazepam, clonazepam, bromazepam and alprazolam) in postmortem human ribs. Powdered bone samples, including marrow remains inside, with the internal standard diazepam-d5 were subjected to enzymatic hydrolysis with 100 μL of β-glucoronidase and were incubated in sodium hydroxide for 1 h in a 70°C oven. Samples underwent liquid phase extraction and ethyl acetate was used as eluent. Chromatography was performed on a fused silica capillary column and the selected-ion-monitoring mode was used for analytes determination. The method was validated in the range 0.1-0.5 ng/mg (depending on the benzodiazepine) to 100 ng/mg with average values of recovery, matrix effect and process efficiency ranged from 83.2 to 94.3%, from 97.3 to 102.1% and from 80.5 to 91.2%, respectively. The intra- and inter-day accuracy was <15%. The procedure was tested in rib specimens obtained during routine autopsies from 20 cases where these benzodiazepines were found in blood. Benzodiazepines were detected in the combined bone and marrow samples in 60% of cases. Lorazepam was detected in bone in the range of 0.3-0.7 ng/mg, nordiazepam at 1.3-4.2 ng/mg and oxazepam at 1.1-1.2 ng/mg. To our knowledge, this protocol for the simultaneous analysis of these benzodiazepines is the first performed and validated using human ribs.

Abstract
In forensic contexts of advanced decomposition, when conventional matrices are no longer available for toxicological analyses, finding alternative matrices is necessary. The skeleton, which is fundamental for anthropologists and geneticists, could be useful also for toxicological purposes. The present study aims to examine what kind of information toxicological analysis performed on bones (the cranium and the ribs) in different states of preservation could provide to the forensic practitioner. Thirty cadavers with known pharmacological history, subjected to forensic autopsy at the Institute of Legal Medicine of Milan, were selected. Rib and cranium samples were collected from each body and separated into two parts in order to create two different states of preservation: One was cleaned from soft tissues and analyzed as a well-preserved bone sample; the other was submitted to a long maceration process, simulating complete skeletonization. All specimens were then processed with accelerated solvent extraction and the eluates analyzed using Q-Exactive™ Orbitrap™ Mass Spectrometer. The analysis of blood and skeletal matrices showed positive results for the tested substances in 63% of cases, mainly benzodiazepines, antidepressants, and drug abuse. Significant Pearson correlations were observed between non-macerated vs. macerated bone samples: r = 0.79 for rib samples, r = 0.61 for cranium samples, and r = 0.69 for all bone samples. As a consequence, the positive results confirm the potential of the bone tissue as an alternative matrix in forensic toxicology, even in cases of extremely decomposed bodies. This study also highlighted important elements for reconstructing the biological profile in cases of forensic anthropological concern.

Abstract
Marijuana or synthetic cannabinoids and alcohol are often used together, with these combinations causing motor impairments that can subsequently lead to motor vehicle accidents. This study investigated the combined use of both synthetic cannabinoids and ethanol and their effect on motor coordination in mice in addition to examining the neurochemical changes in the cerebellum. Ethanol (2 g/kg, i.p.) significantly induced motor impairment in the accelerating rotarod test in mice. Furthermore, ethanol-induced motor impairments were further accentuated when combined with the synthetic cannabinoid, JWH-018 or AB-CHMINACA. The enhancement effects of the synthetic cannabinoids were completely antagonized by pretreatment with the selective CB1 receptor antagonist AM251, but not by the selective CB2 receptor antagonist AM630. Neurochemical study results showed that ethanol caused a reduction in the extracellular glutamate levels in the cerebellum during periods of ethanol-induced motor impairment. In addition to the enhanced motor impairment seen when ethanol was combined with JWH-018, these combinations also enhanced the reduction of the extracellular glutamate levels in the cerebellum. We additionally used microelectrode array recordings to examine the effects of ethanol and/or JWH-018 on the spontaneous network activity in primary cultures from mouse cerebellum. Results showed that ethanol combined with JWH-018 significantly reduced spontaneous neuronal network activity in the primary cerebellar culture. Our findings demonstrate that ethanol-induced motor impairments are enhanced by synthetic cannabinoids, with these effects potentially mediated by CB1 receptors. An accentuated reduction of neurotransmissions in the cerebellum may play an important role in motor impairments caused by ethanol combined with synthetic cannabinoids.

Abstract
![]()
A disposable
electrochemical test strip for the quantitative point-of-care
(POC) determination of acetaminophen (paracetamol) in plasma and finger-prick
whole blood was fabricated. The industrially scalable dry transfer
process of single-walled carbon nanotubes (SWCNTs) and screen printing
of silver were combined to produce integrated electrochemical test
strips. Nafion coating stabilized the potential of the Ag reference
electrode and enabled the selective detection in spiked plasma as
well as in whole blood samples. The test strips were able to detect
acetaminophen in small 40 μL samples with a detection limit
of 0.8 μM and a wide linear range from 1 μM to 2 mM, well
within the required clinical range. After a simple 1:1 dilution of
plasma and whole blood, a quantitative detection with good recoveries
of 79% in plasma and 74% in whole blood was achieved. These results
strongly indicate that these electrodes can be used directly to determine
the unbound acetaminophen fraction without the need for any additional
steps. The developed test strip shows promise as a rapid and simple
POC quantitative acetaminophen assay.

Abstract
Opioids represent a broad family of compounds that can be used in several indications: analgesics, antitussives, opioid substitution therapy (e.g. methadone, buprenorphine…). When these products are misused, they are often addictive. Thus, we aimed to develop an analytical method able to rapidly quantify several opiates and opioids (6-monoacetylmorphine, buprenorphine, codeine, dihydrocodeine, 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolidine, ethylmorphine, heroin, methadone, morphine, nalbuphine, naloxone, norbuprenorphine, norcodeine, norpropoxyphene, oxycodone and propoxyphene) in whole blood by ultra-high performance liquid chromatography combined with high resolution mass spectrometry (UHPLC-HRMS). The validated assay requires only 100 µL of the blood sample. The sample is prepared by a rapid liquid-liquid extraction using 5% zinc sulfate (W/V), methanol and acetonitrile. Calibration curves range from 0.98 to 1000 µg/L, except for buprenorphine (0.39-100 µg/L) and norbuprenorphine (0.20-100 µg/L). Inter- and intra-analytical accuracy was less than 15%. Therefore, we describe the development and full validation of an accurate, sensitive and precise assay using UHPLC-HRMS for the analysis of opioids in whole blood. After validation, this new assay is successfully applied on a routine laboratory application basis.

Bech AB, Clausen T, Waal H, Vindenes V, Edvardsen HE, Frost J, Skeie I. Post-mortem toxicological analyses of blood samples from 107 patients receiving opioid agonist treatment: substances detected and pooled opioid and benzodiazepine concentrations. Addiction 2020; 116:845-855. [PMID: 32738014 DOI: 10.1111/add.15211] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2020] [Revised: 07/14/2020] [Accepted: 07/15/2020] [Indexed: 11/30/2022]
Abstract
AIMS To present the substances and their concentrations detected post-mortem in patients receiving opioid agonist treatment (OAT) stratified by cause of death, estimate the pooled opioid and benzodiazepine concentrations using established conversion factors for blood concentrations from the Norwegian Road Traffic Act, and explore the association between drug-induced cause of death and the pooled opioid and benzodiazepine concentrations. DESIGN Cross-sectional nationwide study. SETTING Norway. PARTICIPANTS One hundred and seven patients who died during OAT (i.e. within 5 days after the last intake of OAT medication) between 1 January 2014 and 31 December 2015, with post-mortem femoral blood available for toxicology. Data were collected from hospital records, the Norwegian Cause of Death Registry and autopsy reports. MEASUREMENTS Presence of alcohol and non-alcohol substances in the bloodstream at time of death, determined through records of toxicology of post-mortem femoral blood. FINDINGS A median of four substances was detected across the causes of death. At least one benzodiazepine was detected in 81 (76%) patients. The median pooled opioid concentration was significantly higher in drug-induced deaths compared with other causes of death (362 ng/mL versus 182 ng/mL, P < 0.001), in contrast to the pooled benzodiazepine concentration (5466 versus 5701 ng/mL, P = 0.353). The multivariate regression analysis showed that only increasing pooled opioid concentration (ng/ML) was associated with increased odds of a drug-induced cause of death (odds ratio, 1.003; 95% confidence interval: 1.001-1.006). CONCLUSIONS In Norway, overall opioid concentration seems to play an important role in drug-induced deaths during opioid agonist treatment in patients prescribed methadone or buprenorphine. Patients prescribed buprenorphine tend to replace their agonist with full agonists, while patients prescribed methadone tend to have high opioid concentrations from methadone as the only opioid.

An evaluation of postmortem concentrations of Δ 9-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Δ 9-tetrahydrocannabinol (THCCOOH). Forensic Sci Int 2020; 315:110414. [PMID: 32738674 DOI: 10.1016/j.forsciint.2020.110414] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 06/01/2020] [Accepted: 07/12/2020] [Indexed: 11/22/2022]
Abstract
Δ9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis, leads to impaired cognitive and psychomotor function resulting in an increased risk of fatal motor vehicle collisions and other traumas resulting in death. It is important to measure cannabinoids in postmortem cases to improve understanding of this growing public safety issue. However, postmortem concentrations of THC and its primary inactive metabolite, 11-nor-9-carboxy-tetrahydrocannabinol (THCCOOH), have not been extensively studied. We aim to further characterize postmortem concentrations of THC and THCCOOH in peripheral blood with and without preservation, central blood, and central "serum" to support improved forensic interpretation. Cannabinoids were extracted from blood and "serum" from twenty-five decedents using solid phase extraction followed by quantification using gas chromatography - mass spectrometry. We evaluated the impact of sample preservation, reported central blood-to-peripheral blood (CB:PB) ratios and blood-to-"serum" ratios, and assessed the relationship of CB:PB and postmortem interval for THC and THCCOOH. Correlations of preserved compared to unpreserved blood were strong with r2 > 0.97. The median CB:PB ratios were 1.1 and 1.3 for THC and THCCOOH, respectively. THCCOOH CB:PB was significantly higher than 1.0 (p-value < 0.001). The CB:PB ratio was only weakly correlated with PMI for both compounds. The median blood-to-"serum" ratio was 1.0 for THC and 0.8 for THCCOOH. The blood-to-"serum" ratio of THCCOOH was significantly lower than 1.0 (p-value < 0.001). Results demonstrated minimal potential for postmortem redistribution of THC and THCCOOH and that the ratio of blood-to-"serum" in postmortem samples differs from the blood-to-plasma ratio established in living humans. Based on these results, it is not recommended to apply a correction factor to THC and THCCOOH concentrations from postmortem blood samples. Our study improves the understanding of postmortem cannabinoid concentrations to support forensic interpretation in cases of fatal motor vehicle accidents.

J Med Toxicol 2020; 17:10-15. [PMID: 32648229 DOI: 10.1007/s13181-020-00795-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 06/14/2020] [Accepted: 06/24/2020] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Buprenorphine is a unique μ-opioid receptor partial agonist with avid receptor binding, nominal euphoric reward, and a ceiling effect on sedation and respiratory depression. Despite a pharmacologic profile that enhances safety, cases of fatal opioid overdose with buprenorphine on postmortem toxicology are reported, but details of these cases in the literature are limited. METHODS A retrospective review of opioid-involved drug overdose fatalities in Rhode Island (RI) from 2016 to 2018 using the RI Department of Health State Unintentional Drug Overdose Reporting System (SUDORS) database. Deaths with buprenorphine on toxicology testing versus opioid-involved overdose deaths without buprenorphine were compared to assess the type and number of co-exposures. RESULTS Of 534 opioid-involved deaths, 29 (5.4%) included buprenorphine and/or norbuprenorphine on toxicology. Most frequent co-exposures are as follows: fentanyl (75.9%), norfentanyl (72.4%), cocaine (41.4%), benzoylecgonine (41.4%), cannabinoids (31.0%), ethanol (31.0%), levamisole (31.0%), and free morphine (31.0%). An average number of co-exposures for fatalities with buprenorphine were 9.24 versus 6.68 in those without buprenorphine. In one case buprenorphine was the only drug listed to cause death; all other fatalities with buprenorphine on toxicology reported additional drugs contributing to death. CONCLUSION Decedents with buprenorphine detected on toxicology testing commonly had documented polysubstance use. Although data are limited, buprenorphine may provide some risk mitigation against full agonist opioid overdose including fentanyl. Further work should explore the use of postmortem concentrations of buprenorphine, norbuprenorphine, and other opioid metabolites to determine the role of buprenorphine in fatal overdose pharmacology.

Abstract
Background: Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control, making people more vulnerable to violence and accidents, with thus a potential association between alcohol consumption and violent deaths. Objective: To assess the association between alcohol consumption and violent deaths in the city of Sao Paulo, Brazil, in 2015, and its relationship with gender, age, cause of death and blood alcohol concentration (BAC) of victims. Methods: A cross-sectional retrospective study was conducted by collection of data from 2,882 victims of violent deaths subjected to examination of BAC from the archives of the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Results: Alcohol was detected in blood samples of 27.06% of the victims and mean BAC levels were 1.92 ± 1.24 g/L. The mean age of the victims was 33.49 ± 15.19 years. The majority of the victims were male (84.14%) and the prevalence of positive BAC was higher amongst men (28.74%) than women (18.16%). Homicide was the most prevalent cause of death in the sample (36.57%), but there were a higher proportion of traffic accidents victims with positive BAC (32.01%), as well as higher BAC levels in these victims (46.77% in the range of 1.6-2.5 g/L). Conclusions: The results obtained in this study support a potential association between alcohol consumption and violent deaths in the city of Sao Paulo, mainly in traffic accidents victims.

Abstract
In clinical settings, the dosing and differential diagnosis of the poisoning of morphine (MO) and codeine (CO) is challenging due to interindividual variations in metabolism. However, direct electrochemical detection of these analytes from biological matrices is inherently challenging due to interference from large concentrations of anions, such as ascorbic acid (AA) and uric acid (UA), as well as fouling of the electrode by proteins. In this work, a disposable Nafion-coated single-walled carbon nanotube network (SWCNT) electrode was developed. We show facile electron transfer and efficient charge separation between the interfering anions and positively charged MO and CO, as well as significantly reduced matrix effect in human plasma. The Nafion coating alters the voltammetric response of MO and CO, enabling simultaneous detection. With this SWCNT/Nafion electrode, two linear ranges of 0.05-1 and 1-10 μM were found for MO and one linear range of 0.1-50 μM for CO. Moreover, the selective and simultaneous detection of MO and CO was achieved in large excess of AA and UA, as well as, for the first time, in unprocessed human plasma. The favorable properties of this electrode enabled measurements in plasma with only mild dilution and without the precipitation of proteins.

Abstract
In the US, the use of synthetic opioids (e.g. fentanyl and derivatives) has become an increasing health issue with thousands of overdose deaths being observed since 2013. With the high mortality rate associated with these substances, postmortem analyses and interpretation of synthetic opioids has become extremely important. However, due to the novelty of these compounds, the available data are limited and provides challenges to toxicologists. The objectives of this study were (1) to develop and validate analytical methods for the determination of synthetic opioids in vitreous humor and brain, and (2) to investigate the postmortem distribution of new synthetic opioids in blood, vitreous humor, and brain tissue. Vitreous humor (0.5mL) and brain tissue (5g) homogenized in water (diluted 1:3, w/w) were extracted by mixed mode cation exchange-reversed phase solid phase extraction. Extracts were analyzed by liquid chromatography tandem mass spectrometry (LC-MSMS). The chromatographic separation was performed by reversed-phase with 0.1% formic acid in water and in acetonitrile as mobile phases in gradient mode, with a total run time of 21min. Data were acquired with ESI+ in dynamic multiple reaction mode (dMRM), monitoring 2 transitions per compound. The methods were succesfully validated following SWGTOX guidelines, with limits of quantification of 0.1ng/mL in vitreous humor and 0.1ng/g in brain. Fifty-eight authentic case samples from the New York City Office of the Chief Medical Examiner (NYC-OCME) were analyzed to assess the distribution and detectability of synthetic opioids in these postmortem samples. Of the fifteen synthetic opioids included in the method, six synthetic opioids and metabolites (4-ANPP, acetylfentanyl, fentanyl, furanylfentanyl, norfentanyl, U-47700) were detected in the authentic cases. Concentrations for most analytes were within the 0.1 to 100ng/mL or ng/g calibration range across all three matrices, with only concentrations from acetylfentanyl and U-47700 exceeding 100ng/mL or ng/g. The highest concentrations were observed in brain (except norfentanyl), followed by blood and vitreous humor. Most analytes were detected in all three matrices in a given case. This was followed by detection of an analyte in combinations of brain and another matrix or brain only. Through the case analyses, vitreous humor and brain demonstrated to be viable alternatives to blood when performing postmortem analyses of synthetic opioids. Brain exhibited a higher detectability for most analytes when compared to blood and vitreous humor.

Abstract
Fatal road traffic crashes are often related to speeding, non-use of a seatbelt, and alcohol/drug-impaired driving. The aim of this study was to examine associations between driving under the influence of drugs and/or alcohol and driver-related risk factors that have been reported as significantly contributing causes of fatal road traffic crashes. The data were extracted from Norwegian road traffic crash registries and forensic toxicology databases. Drug/alcohol investigated car and van drivers and motorcycle riders fatally injured in road traffic crashes in Norway during 2005-2015 were included in this study (n = 772). Drug and alcohol concentrations corresponding to 0.5 g/kg alcohol in blood were used as the lower limits for categorising drivers/riders as impaired; 0.2 g/kg was the upper limit for being categorised as sober. Associations between driver-related risk factors and impairment from specific substance groups were calculated using multivariable logistic regression, adjusted for other substance groups, age, and sex, and were reported when the confidence intervals did not contain the value 1 or lower. Substances found in concentrations above the impairment limits were mainly alcohol (20%), medicinal drugs (10%: benzodiazepines, opioids, z-hypnotics), stimulants (5%: amphetamines, methylphenidate, and cocaine), and cannabis (4%: THC). The drug/alcohol-impaired drivers had compared to the sober drivers more often been speeding (68% versus 32%), not used a seatbelt (69% versus 30%), and been driving without a valid driver license (26% versus 1%). Logistic regression analysis showed that impairment from alcohol or stimulants (mainly amphetamines) was associated with all three risk factors, medicinal drugs with all except speeding, and impairment from cannabis (THC) with not having a valid driver license. Among motorcycle riders, drug/alcohol impairment was associated with not having a valid driver license and non-use of a helmet. At least one of the risk factors speeding, non-use of a seatbelt/helmet, and driving without a valid license were present among the vast majority of the drug/alcohol-impaired fatally injured drivers and riders, and also among more than half of the fatally injured sober drivers.

Abstract
A porous and hydrophilic sorbent material was used in an extraction system, assisted by electric fields, for the extraction of cocaine in saliva and subsequent determination by ultra-high-performance liquid chromatography associated with sequential triple quadrupole mass spectrometry (UHPLC-MS/MS). The cellulose-based material was characterized by scanning electron microscopy, infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction. The time and voltage variables applied in the extraction process were investigated through a Doehlert experimental design, and with the best conditions found (35min and 300 V) some validation parameters were evaluated. The established working range was 1-100 μg L-1 (R2 > 0.99), and the detection and quantification limits determined were 0.3 and 0.8 μg L-1, respectively. Recoveries from 80 to 115% and coefficient of variation ≤15 and 16% for intra-day and inter-day assays, respectively, were obtained for sample concentrations of LOQ, 5, 25, and 75 μg L-1, indicating satisfactory accuracy and precision for the proposed method. In addition, the method presented no matrix effect, and the extraction efficiency was between 56 and 70%. The results showed that the material used has adequate physicochemical characteristics and can be applied as a sorbent and electrolyte support in multiphase extractions using electric fields.

Metformin - Postmortem fatal and non-fatal reference concentrations in femoral blood and risk factors associated with fatal intoxications. Forensic Sci Int 2019; 303:109935. [PMID: 31491622 DOI: 10.1016/j.forsciint.2019.109935] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 08/05/2019] [Accepted: 08/21/2019] [Indexed: 11/23/2022]
Abstract
BACKGROUND & OBJECTIVES To improve the interpretation of fatal intoxications by establishing fatal and non-fatal reference concentrations of metformin in postmortem femoral blood and to further evaluate risk factors associated with fatal metformin intoxication. METHODS All forensic autopsies in Sweden where metformin was detected in femoral blood 2011-2016 were identified in the National Board of Forensic Medicine databases (NFMD). The cases were classified as single substance intoxications, A (n = 22), multiple substance intoxications, B (N = 7) and postmortem controls, C (N = 13). The control group consisted of cases where metformin was detected, but the cause of death excluded the incapacitation by metformin or other substances. Strict inclusion criteria were used, and all postmortem cases were assessed by two independent reviewers. All other cases where the inclusion criteria of groups A-C where not met formed group O (N = 78). The forensic findings logged in the NFMD where linked to national registers whereby information on comorbidities, dispensed drugs and clinical data could be obtained. RESULTS The mean age was 66 ± 10 years in the total study population and did not differ between the groups. The proportion of men was 64% in group A, 71% in B, 77% in C and 74% in group O. The median values of metformin in group A (48.5 μg/g; range 13.0-210 μg/g) and B (21.0 μg/g; range 4.40-95.0 μg/g) were significantly (p < 0.001 and p = 0.015 respectively) higher than those of the control group C (2.30 μg/g ; range 0.70-21.0 μg/g). The median concentration of metformin in group A and B was also significantly higher than in group O (4.60 μg/g; range 0.64-54.0 μg/g) (p < 0.001 and p = 0.040 respectively). The results suggest that intoxication with metformin as a cause of death should be considered when the postmortem femoral blood level exceeds about 10 μg/g, although higher levels may be seen in postmortem in cases without incapacitation. The metformin intoxication was confirmed to be intentional in 23% (n = 5) of the single intoxications. Underlying factors identified as important for the remaining fatal metformin intoxications included living alone, any contraindication for the use of metformin, known alcohol abuse and a history of stroke or cardiovascular disease. CONCLUSIONS The reported post mortem femoral blood concentrations of metformin can hopefully contribute to a better interpretation of results in suspected poisonings and obscure cases. Living in a single household, history of cardiovascular disease and contraindications, predominantly alcohol abuse, were associated with fatal metformin intoxication.

Abstract
Forty-three fatalities involving the potent synthetic cannabinoid, 5-Fluoro-ADB, are summarized. For each case, a description of the terminal event, autopsy findings, cause of death, qualitative identification of 5-Fluoro-ADB and its ester hydrolysis metabolite, 5-Fluoro-ADB metabolite 7, in urine, and the quantitative values obtained in the blood specimens are outlined. Central blood concentrations ranged from 0.010 to 2.2 ng/mL for 5-Fluoro-ADB and 2.0 to 166 ng/mL for 5-Fluoro-ADB metabolite 7. Peripheral blood concentrations ranged from 0.010 to 0.77 ng/mL and 2.0 to 110 ng/mL for 5-Fluoro-ADB and 5-Fluoro-ADB metabolite 7, respectively. The majority of cases resulted in central to peripheral blood concentration ratios greater than 1 for 5-Fluoro-ADB (58%) and 5-Fluoro-ADB metabolite 7 (71%) suggesting that postmortem redistribution occurs to some extent. Combining the increased cardiac weight and/or gastric volume and toxicology data identifying 5-Fluoro-ADB, it is hypothesized that abuse of this substance may precipitate a dysrhythmia and cause sudden death.

Abstract
AIMS To investigate the extent of variability in the reporting of heroin-related deaths in Victoria, Australia. Additionally, to identify opportunities to improve the accuracy and consistency of heroin-related death reporting by examining variability in the attribution, death certification, classification and coding of heroin-related death cases. METHODS Heroin-related deaths in Victoria, Australia during a 2-year period (2012-13) were identified using the National Coronial Information System (NCIS) and used as the 'gold standard' measure in this study. Heroin-related death data from the Australian Institute of Health and Welfare (AIHW) and Australian Bureau of Statistics (ABS) were then compared. Differences in the number of deaths reported as well as the classification and coding assigned to the identified heroin-related death cases were investigated by cross-referencing these data sets and examining the assigned ICD-10 codes. RESULTS A total of 243 heroin-related deaths were identified through the NCIS compared with 165 heroin-related deaths reported by the AIHW and assigned the heroin-specific ICD-10 code of T40.1. Forty per cent of all the missed heroin-related death cases resulted from either the attribution of the death to morphine toxicity or with non-specific drug toxicity certification; 30% occurred where the cases had been attributed to heroin but there were irregularities in death certification. Additional missed heroin-related death cases occurred as a result of late initial registration of these deaths to the Registry of Births, Deaths and Marriages, and where these cases were then not assessed by the ABS for classification and coding purposes. CONCLUSIONS In Victoria, Australia, in 2012 and 2013, the overall number of heroin-related deaths was under-reported by 32% compared with the number of deaths currently identified by the Australian Bureau of Statistics and reported by the Australian Institute of Health and Welfare.

Abstract
In the last decades, more and more new psychoactive substances (NPS) were introduced on the drug market which were sold as "legal" alternatives for classic drugs and misused medications. Due to an increased number of available substances and a growing utilization by users of common drugs but also by inexperienced users because of the supposed "legal" status, also undesired adverse effects of these NPS, at worst leading to death, became apparent. This review summarizes fatalities previously described in scientific literature which were attributed to the use of NPS or such cases, in which intake of NPS was proven or even assumed to contribute to death. This summary includes an overview of substances involved (particularly synthetic cannabinoids ("spice"), novel opioids and synthetic cathinones ("bath salts")) as well as of postmortem concentrations determined in various biological matrices. The compiled data assist forensic toxicologists with the interpretation of death cases involving NPS.
