Abstract
The scientific literature contains little reliable data regarding new psychoactive substances and designer drugs, making it difficult to assess toxic blood levels and potentially lethal threshold. Here, we report a fatal co-intoxication involving two uncommon drugs ‒ alpha-methyltryptamine (AMT) and 5-(2-methylaminopropyl)-benzofuran (5-MAPB) ‒ combined with exposure to benzodiazepines, ephedrine, and norephedrine. AMT and 5-MAPB were quantified using ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC/MS-MS), revealing concentrations of AMT 4690 ng/mL and 5-MAPB 101 ng/mL in postmortem peripheral blood. We additionally reviewed the literature to help interpret the likely roles of these molecules in the occurrence of death.

Abstract
There is an increasing number of people affected worldwide by mental health disorders, such as depression and anxiety. One of the main courses of treatment, along with psychotherapy, is the use of psychoactive medications, like antidepressants and benzodiazepines. Also, the unprescribed use of these substances is a concerning public health issue. Hence, the analysis of psychotropic medications is mandatory in postmortem toxicology and various biological samples can be used for this detection, among them the vitreous humor (VH) stands out. Also, there is a demand for more sustainable and more efficient extraction methodologies according to green chemistry. An example is solid phase microextraction techniques (SPME), which use a solid sorbent and small solvent amounts. Biosorbents are substances of natural origin with sorptive properties, and they have been successfully used in SPME in environmental toxicology for water analysis, mainly. This study aimed to develop a sustainable, fast, cheap and simple SPME methodology using cork sheet strips as a biosorbent, to extract antidepressants, benzodiazepines and others from VH samples by liquid chromatography coupled to tandem mass spectrometry. The extraction was conducted in a 96-well plate using 200 µL of VH and optimization of relevant parameters for extraction was performed. For solvent optimization, two simplex-centroid experiments were planned for extraction and desorption and to evaluate time and pH, a Doehlert design experiment was performed. The analytical method for the determination and quantification of 17 substances was validated. The quantification limits were 5 ng/mL for all analytes and the calibration curves were linear between 5 and 30 ng/mL. This study was able to develop an efficient, cheap, simple and fast microextraction method for 17 analytes in VH, using strips of cork sheet for extraction and a 96-well plate as a container. Furthermore, this approach system could be automated for routine toxicology laboratories.

Abstract
Depression is one of the most prevalent but severe of mental disorders, affecting thousands of individuals across the globe. Depression, in its most extreme form, may result in self-harm and an increased likelihood of suicide. Antidepressant drugs are first-line medications to treat mental disorders. Unfortunately, these medications are also prescribed for other in- and off-label conditions, such as deficit/hyperactivity disorders, attention disorders, migraine, smoking cessation, eating disorders, fibromyalgia, pain, and insomnia. This results in an increase in the use of antidepressant medications, leading to clinical and forensic overdose cases that could be either accidental or deliberate. The findings revealed that people who used antidepressants had a 33% greater chance of dying sooner than expected, compared to those who did not take the medications. Analytical techniques for precisely identifying and detecting antidepressants and their metabolic products in a variety of biological matrices are greatly needed to be developed and made available. Hence, this study attempts to discuss various analytical techniques used to identify and determine antidepressants in various biological matrices, which include urine, blood, oral fluid (saliva), and tissues, which are commonly encountered in clinical and forensic science laboratories.

Abstract
Benzodiazepines (BZDs) and Z-drugs have been particularly important treatments for sleeping and anxiety disorders for many years. However, recently, a number of new benzodiazepines (named designer benzodiazepines, DBZDs) were synthesised, but some of them have never been used in the clinic; they reached the black drug market as new psychoactive substances and are used for recreational purposes. The abuse of these substances has led to many crimes and even deaths. Therefore, it is necessary to develop new methods for their quantification for forensic and clinical toxicology. A liquid chromatography-tandem mass spectrometry-based method was developed for the simultaneous determination of 20 classical BZDS, 4 DBZDs and 3 Z-hypnotic drugs in human whole blood. As a sample preparation step, liquid-liquid extraction requiring the use of only 0.5 mL of blood sample and 1 mL of extraction solvent was applied. The selectivity, linearity, carry-over effects, limits of detection (LOD) and quantification (LOQ), precision, accuracy (both intra- and inter-day assays) and recovery were evaluated for validation. Calibration curves were linear with r values > 0.98. The LODs ranged from 0.01 to 0.33, and the LOQs were assumed to be 1 ng/mL. Inter-day precisions and accuracies were in the ranges of 87.8% - 108.5% and 1.8% - 11.2%, respectively. The recovery values ranged from 81.0% to 106.7%. The developed method proved to be sensitive, specific, simple, and fast and can be quickly modified and expanded for new compounds by the optimization of MRM. The method was applied for analysis of blood samples in 145 toxicological cases over a three-year study (2017 - 2019), which allowed us to obtain information on the prevalence of the use of these substances. The most frequently determined compounds were nordazepam (87 cases; 60%), diazepam (81 cases; 55.9%), temazepam (72 cases; 49.7%), oxazepam (56 cases; 38.7%), and midazolam (36 cases; 24.8%). The ranges of concentrations were wide and are presented as box plots. The results were used for the preparation of medico-legal opinions, which proved the utility of the method for routine toxicology analyses.

Abstract
Vitreous humor has become in recent years an important alternative biological fluid in forensic toxicological analysis especially for the investigation of cases where alcohol and drugs of abuse are involved but there is limited scientific information regarding the distribution of antidepressant drugs in this material. This work aimed to study the distribution of antidepressant drugs in vitreous humor and to estimate the blood/vitreous humor concentration ratios of these drugs. For this purpose, a GC/MS method for the simultaneous determination of 9 antidepressant drugs, namely amitriptyline, nortriptyline, citalopram, clomipramine, fluoxetine, maprotiline, mirtazapine, sertraline and venlafaxine, and 4 of their metabolites, namely desmethylmaprotiline, desmethylmirtazapine, desmethylsertraline, O-desmethylvenlafaxine, was developed and validated. The developed method includes solid-phase extraction followed by derivatization with Heptafluorobutyric Anhydride. For all analytes, LOD and LOQ were 1.50 and 5.00ng/mL, respectively, and the calibration curves were linear within the dynamic range of 5.00-500.0ng/mL (R2≥0.990). The absolute recovery was found to be ≥86.3 % for all analytes. The accuracy (%Er) was found to range between -6.58 and 6.18 %, whereas the precision (%RSD) was less than 10.9 % for all analytes. The developed method was successfully applied to vitreous humor samples from 43 blood positive cases for antidepressant drugs. Whenever antidepressant drugs were detected in blood, they were also detected in the respective vitreous humor samples. The vitreous humor/blood concentration ratios were also calculated and were found to range from 0.04-7.07. Citalopram, mirtazapine, and its metabolite desmethylmirtazapine as well as venlafaxine and its metabolite O-desmethylvenlafaxine were the most identified substances in these samples (n≥4) and their results were better statistically evaluated. Our results suggest that vitreous humor could be an appropriate matrix for the determination of antidepressants in postmortem toxicology.

Abstract
A micellar liquid chromatographic method has been developed for the simultaneous determination of citalopram hydrobromide (CTA) with its two demethylated metabolites namely; desmethyl citalopram hydrochloride (DCTA) and didesmethyl citalopram tartrate (DDCTA). Separation was conducted on a C18 column using a mobile phase composed of 0.18 M sodium dodecyl sulphate (SDS), 15% 1-propanol, 0.3% tri-ethylamine, adjusted to pH 4 with 0.2 M o-phosphoric acid and adopting UV detection at 240 nm. Analysis was performed at 60 °C applying a flow rate of 2 mL/min. The proposed method was linear over the concentration ranges of 1.0-200.0, 0.6-200.0, and 0.5-200.0 μg/mL for CTA, DCTA, and DDCTA respectively, with corresponding limits of detection (LOD) of 0.5, 0.4, and 0.3 μg/mL and limits of quantification (LOQ) of 0.8, 0.5, and 0.4 μg/mL. The method was fully validated which allowed its application for the determination of CTA in its tablets. Moreover, the proposed method was extended to assay CTA with its metabolites in rat tissue organs samples which allowed the method to be used as a diagnostic tool in forensic toxicology.

Abstract
In this study, we describe a simple and rapid method for the determination of the antipsychotic drug clozapine and five commonly co-administered antidepressants - bupropion, mirtazapine, sertraline, clomipramine and citalopram - in serum, plasma and whole blood. Sample preparation includes solid phase extraction of analytes and determination of drug concentrations by gas chromatography-mass spectrometry without any derivatization steps. The method was fully validated according to international criteria and can be successfully applied for routine analyses. Correlation coefficients of calibration curves for the tested drugs in the three specimens were in the range 0.9977-0.9999. Intra-day and inter-day precisions ranged from 0.81-7.85% and 3.60-12.91% respectively for the studied analytes and matrices. Recoveries were satisfactory for different concentrations of each drug in each specimen allowing accurate determinations in the range from sub-therapeutic to toxic levels. The presented method shows acceptable sensitivity, linearity in wide concentration ranges (sub-therapeutic, therapeutic, supra-therapeutic/toxic levels), it is simple and rapid and it is applicable for qualitative and quantitative routine toxicological analyses of clinical and postmortem cases.

Abstract
Vitreous humor (VH) is a gelatinous substance contained in the posterior chamber of the eye, playing a mechanical role in the eyeball. It has been the subject of numerous studies in various forensic applications, primarily for the assessment of postmortem interval and for postmortem chemical analysis. Since most of the xenobiotics present in the bloodstream are detected in VH after crossing the selective blood-retinal barrier, VH is an alternative matrix useful for forensic toxicology. VH analysis offers particular advantages over other biological matrices: it is less prone to postmortem redistribution, is easy to collect, has relatively few interfering compounds for the analytical process, and shows sample stability over time after death. The present study is an overview of VH physiology, drug transport and elimination. Collection, storage, analytical techniques and interpretation of results from qualitative and quantitative points of view are dealt with. The distribution of xenobiotics in VH samples is thus discussed and illustrated by a table reporting the concentrations of 106 drugs from more than 300 case reports. For this purpose, a survey was conducted of publications found in the MEDLINE database from 1969 through April 30, 2015.

Abstract
Sudden infant death syndrome (SIDS) and sudden intrauterine unexpected death syndrome (SIUDS) are an unresolved teaser in the social-medical and health setting of modern medicine and are the result of multifactorial interactions. Recently, prenatal exposure to environmental contaminants has been associated with negative pregnancy outcomes, and verification of their presence in fetal and newborn tissues is of crucial importance. A gas chromatography-tandem mass spectrometry (MS/MS) method, using a triple quadrupole analyzer, is proposed to assess the presence of 20 organochlorine pesticides, two organophosphate pesticides, one carbamate (boscalid), and a phenol (bisphenol A) in human brain tissues. Samples were collected during autopsies of infants and fetuses that died suddenly without any evident cause. The method involves a liquid-solid extraction using n-hexane as the extraction solvent. The extracts were purified with Florisil cartridges prior to the final determination. Recovery experiments using lamb brain spiked at three different concentrations in the range of 1-50 ng g(-1) were performed, with recoveries ranging from 79 to 106%. Intraday and interday repeatability were evaluated, and relative standard deviations lower than 10% and 18%, respectively, were obtained. The selectivity and sensitivity achieved in multiple reaction monitoring mode allowed us to achieve quantification and confirmation in a real matrix at levels as low as 0.2-0.6 ng g(-1). Two MS/MS transitions were acquired for each analyte, using the Q/q ratio as the confirmatory parameter. This method was applied to the analysis of 14 cerebral cortex samples (ten SIUDS and four SIDS cases), and confirmed the presence of several selected compounds.

Abstract
This paper describes a new method for the determination of citalopram in biological fluids using molecularly imprinted solid-phase extraction as the sample cleanup technique combined with high performance liquid chromatography. The molecularly imprinted polymers were prepared using methacrylic acid as functional monomer, ethylene glycol dimethacrylate as crosslinker, chloroform as porogen and citalopram hydrobromide as the template molecule. The novel imprinted polymer was used as a solid-phase extraction sorbent for the extraction of citalopram from human serum and urine. Effective parameters on citalopram retention were studied. The optimal conditions for molecularly imprinted solid-phase extraction consisted of conditioning with 1 mL methanol and 1 mL of deionized water at neutral pH, loading of citalopram sample (50 μg L(-1)) at pH 9.0, washing using 1 mL acetone and elution with 3 × 1 mL of 10 % (v/v) acetic acid in methanol. The MIP selectivity was evaluated by checking several substances with similar molecular structures to that of citalopram. Results from the HPLC analyses showed that the calibration curve of citalopram using MIP from human serum and urine is linear in the ranges of 1-100 and 2-120 μg L(-1) with good precisions (2.5 and 1.5 % for 10.0 μg L(-1)), and recoveries (between 82-86 and 83-85 %), respectively.
