RESUMEN

Forensic chemistry literature has grown exponentially, with many analytical techniques being used to provide valuable information to help solve criminal cases. Among them, matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS), particularly MALDI MS imaging (MALDI MSI), has shown much potential in forensic applications. Due to its high specificity, MALDI MSI can analyze a wide variety of compounds in complex samples without extensive sample preparation, providing chemical profiles and spatial distributions of given analyte(s). This review introduces MALDI MS(I) to forensic scientists with a focus on its basic principles and the applications of MALDI MS(I) to the analysis of fingerprints, drugs of abuse, and their metabolites in hair, medicine samples, animal tissues, and inks in documents.

RESUMEN

BACKGROUND: The use of psychoactive substances (PSs) during pregnancy is a major public health concern because of their increasing prevalence worldwide. This study examined the understudied issue of gestational PS consumption in a cohort of Argentine delivering mothers. METHODS: A cross-sectional pilot study involving 51 women receiving delivery care was conducted at the Santa Rosa Hospital in La Pampa, Argentina. Information on maternal sociodemographic characteristics, pregnancy history, and drug use was obtained through standardized interviews. Maternal hair samples were analyzed for alcohol, tobacco, licit, illicit, and prescription substance biomarkers using ultra-high-performance liquid chromatography high-resolution mass spectrometry and gas chromatography mass spectrometry. RESULTS: During pregnancy, 49.0% of participants reported alcohol consumption, 25.5% reported tobacco use, and 23.5% reported cannabis use. Hair samples from 56.9% of the women were positive for illicit PSs, with the most frequent being cocaine (41.2%) and cannabis (15.7%). Among the women, 47.1% consumed alcohol during pregnancy. Of the 24 women with hair ethyl glucuronide ≥5 pg/mg, 33.3% drank until the end of gestation and 58.3% started a social drinking habit in the second half. The analysis also detected prescription substances (anticonvulsants, antidepressants, methadone, opioids, antihistamines, antiemetics, and analgesics), caffeine (70.6%), lidocaine, and levamisole, some of which were cocaine or opioid adulterants. CONCLUSIONS: This is the first study to objectively assess the consumption of licit and illicit PSs during pregnancy in Argentina. In contrast to most nearby countries, cocaine was the most detected illicit PS in this cohort of Argentine delivering women. This finding highlights the importance of regular monitoring of local trends in PS use during pregnancy.

RESUMEN

Cocaine and antidepressants rank high globally in substance consumption, emphasizing their impact on public health. The determination of these compounds and related substances in biological samples is crucial for forensic toxicology. This study focused on developing an innovative analytical method for the determination of cocaine, antidepressants, and their related metabolites in postmortem blood samples, using unmodified commercial Fe3O4 nanoparticles as a sorbent for dispersive magnetic solid-phase extraction (m-d-SPE), coupled with liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) analysis. An aliquot of 100 µL of whole blood and 5 µL of the internal standard pool were added to 30 mg of nanoparticles. The nanoparticles were separated from the sample using a neodymium magnet inserted into a 3D-printed microtube rack. The liquid was then discarded, followed by desorption with 300 µL of 1/1/1 acetonitrile/methanol/ethyl acetate. The sample was vortexed and separated, and 1.5 µL of the organic supernatant was injected into the LC-MS/MS. The method was acceptably validated and successfully applied to 263 postmortem blood samples. All samples evaluated in this study were positive for at least one substance. The most frequent analyte was benzoylecgonine, followed by cocaine and cocaethylene. The most common antidepressants encountered in the analyzed samples were citalopram and fluoxetine, followed by fluoxetine's metabolite norfluoxetine. This study describes the first report of this sorbent in postmortem blood analysis, demonstrating satisfactory results for linearity, precision, accuracy, and selectivity for all compounds. The method's applicability was confirmed, establishing it as an efficient and sustainable alternative to traditional techniques for forensic casework.

RESUMEN

Illicit drug use is a serious and complex public health problem, not only due to the severity of the health damage but also to the social implications, such as marginalization and drug trafficking. Currently, cocaine (COC) is among the most abused drugs worldwide with about 22 million users. Drug abuse has also been found in women during the pregnancy period, which has shed light on a new group for epidemiology. The diagnosis of COC use in these cases usually depends largely on the mother's reports, which in several cases omit or deny consumption. Therefore, considering physical-chemical methods of sample preparation and exposure biomarkers, the development of analytic toxicological methods can help to confirm drug use during pregnancy. Thus, the objective of the present work was to develop an analytical method based on dispersive liquid-liquid microextraction for the determination of COC analytes, using umbilical cord tissue as an alternative biological matrix, and detection by gas chromatography coupled to mass spectrometry. Therefore, after optimization, the dispersive liquid-liquid microextraction method was fully validated for quantification of COC, benzoylecgonine, cocaethylene, ecgonine, ecgonine methyl ester and norcocaine. The limits of detection were between 15 and 25 ng/g, the limits of quantification were 30 ng/g for ecgonine and 25 ng/g for the other analytes. Linearity ranged from the limits of quantification to 1,000 ng/g. Coefficients of variation for intra-assay precision were <18.5%, inter-assay was <8.75% and bias was <16.4% for all controls. The developed method was applied in 10 suspected positive samples, based on the mother's report and maternal urine screening and confirmation. COC, benzoylecgonine, ecgonine and ecgonine methyl ester were quantified in four umbilical cords with concentrations that ranged from 39.6 to 420.5 ng/g.

RESUMEN

New psychoactive substances (NPS) are often synthesized via small changes in the molecular structure, producing drugs whose effect and potency are not yet fully known. Ketamine is one of the oldest NPS, with therapeutic use in human and veterinary medicine authorized in several countries, being metabolized mainly into norketamine and 6-hydroxy-norketamine. Furthermore, two structural analogues of ketamine have recently been identified, deschloroketamine and 2-fluorodeschloroketamine, marketed as drugs of abuse. To comply with Green Analytical Toxicology (GAT) fundamentals, miniaturized techniques such as dispersive liquid-liquid microextraction (DLLME) were employed to determine toxicants in biological fluids. An analytical method for determining ketamine, its metabolites and its analogues in oral fluid was fully developed and validated by using DLLME and liquid chromatography-tandem mass spectrometry (LC-MS-MS). The extraction parameters were optimized by multivariate analysis, obtaining the best conditions with 200 µL of sample, 100 µL of methanol as dispersive solvent and 50 µL of chloroform as extractor solvent. Linearity was obtained from 10 to 1,000 ng/mL, with limit of detection (LOD) and lower limit of quantification (LLOQ) at 10 ng/mL. Imprecision (% relative standard deviation) and bias (%) were less than 8.2% and 9.5%, respectively. The matrix effect did not exceed 10.6%, and the recovery values varied from 24% to 42%. No matrix interference and good selectivity in the evaluation of 10 different sources of oral fluid and 42 drugs at 500 ng/mL, respectively, were observed. The method was applied in the analysis of 29 authentic oral fluid samples and had its green characteristic evaluated by three different tools: the Green Analytical Procedure Index (GAPI), the Analytical Eco-Scale and the Analytical GREEnness (AGREE) metrics.

RESUMEN

Urine toxicological analysis is a relevant tool in both clinical and forensic scenarios, enabling the diagnosis of acute poisonings, elucidation of deaths, verification of substance use in the workplace and identification of drug-facilitated crimes. For these analyses, the dilute-and-shoot technique associated with liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS) is a promising alternative since it has demonstrated satisfactory results and broad applicability. This study developed and validated a comprehensive LC-MS-MS screening method to analyze 95 illicit drugs and medicines in urine samples and application to clinical and forensic Brazilian cases. The dilute-and-shoot protocol was defined through multivariate optimization studies and was set using 100 µL of sample and 300 µL of solvent. The total chromatographic run time was 7.5 min. The method was validated following the recommendations of the ANSI/ASB Standard 036 Guideline. The lower limits of quantification varied from 20 to 100 ng/mL. Within-run and between-run precision coefficient of variations% were <20%, and bias was within ± 20%. Only 4 of the 95 analytes presented significant ionization suppression or enhancement (>25%). As proof of applicability, 839 urine samples from in vivo and postmortem cases were analyzed. In total, 90.9% of the analyzed samples were positive for at least one substance, and 78 of the 95 analytes were detected. The most prevalent substances were lidocaine (40.2%), acetaminophen (38.0%) and benzoylecgonine (31.5%). The developed method proved to be an efficient and simplified alternative for analyzing 95 therapeutic and illicit drugs in urine samples. Additionally, the results obtained from sample analysis are essential for understanding the profile of Brazilian substance use, serving as a valuable database for the promotion of health and safety public policies.

RESUMEN

RESUMO. A implementação da reforma psiquiátrica é tema de recorrentes discussões no campo da saúde mental. Essa implementação não é padrão para todas as localidades brasileiras, uma vez que depende dos recursos materiais, humanos e aspectos culturais de cada região. A esta singularidade retoma-se a noção de arranjo assistencial. Este trabalho se propôs a conhecer a implementação numa regional de saúde da região Sul. Foi realizado um mapeamento descritivo, seguindo método empírico-fenomenológico. Descrevem-se serviços que acolhem todos os públicos, mas que encontram dificuldades no trabalho com a população usuária de álcool e outras drogas. Foram elencados sete dispositivos assistenciais: acolhimento, grupos terapêuticos, oficinas, atendimentos individuais, uso da medicação, encaminhamentos e reuniões de equipe. Expõe-se a ideia de que a estrutura de um serviço de saúde mental não pode ser estanque. Os arranjos assistenciais estão relacionados às vivências e soluções criativas e humanas como também práticas irrefletidas e normatizadoras na atenção do sofrimento mental.

RESUMEN. La implementación de la reforma psiquiátrica no se encuentra estandarizada para todas las regiones brasileras, una vez que eso depende de recursos materiales, humanos y de aspectos culturales. Por cuenta de esta singularidad, se retoma la noción de arreglo asistencial. En este trabajo se propone conocer la implementación en una regional de salud de sur de Brasil. Se realizó un mapeo descriptivo, siguiendo el método empírico-fenomenológico. Se describen servicios que acogen a todos los públicos, pero que encuentran dificultades en el trabajo con usuarios de alcohol y drogas. Fueran enumerados siete dispositivos asistenciales: Acogimiento, grupos terapéuticos, talleres, atendimientos individuales, uso de medicación, encaminamientos y reuniones de equipo. Se expone la idea de que la estructura de un servicio de Salud Mental no puede ser hermética. Los arreglos asistenciales están relacionados con las vivencias y soluciones creativas y humanas como también prácticas irreflexivas y normalizadoras en la atención del sufrimiento mental.

ABSTRACT. The psychiatric reform is not standard in all Brazilian places, as it depends on different factors such as material, human and cultural aspects of each region. As for its singularity, it is seen as a care arrangement. This article aims to study the psychosocial care network on a regional health department in south Brazil. A descriptive mapping has been performed, following the empirical-phenomenological method. The services described welcome the entire community, people from all walks of life, but when it comes Drug and Alcohol addicted, the approach becomes more challenging. There have been seven care services listed: Hosting, Therapeutic Groups, Workshops, Individual Treatment, Medication usage, Referrals and Support Group Meetings. The approach for care arrangement is related to the creative experiences and human solutions as well as thoughtless and normative practices in the attention of mental suffering.

RESUMEN

Cobalt was included on the World Anti-Doping Agency Prohibited List in 2015 due to its effect on stimulus of erythropoiesis via stabilization of hypoxia-inducible factor. Although it has proven benefits for performance enhancement, the unavailability of inductively coupled plasma-mass spectrometry on routine of the accredited laboratories is a factor that reduces its applicability in anti-doping analysis. Therefore, an analytical method for quantification of urinary cobalt as its diethyldithiocarbamate complex by liquid chromatography coupled with high-resolution tandem mass spectrometry was developed and validated. Palladium was proposed as internal standard and rhodium as a complexation control. A microwave-assisted acid digestion of the urine samples was essential, not only to eliminate the matrix effect but mainly to avoid the non-specific bond of cobalt to endogenous molecules. A linear method was obtained over the studied range from a negative urine control to a spiked concentration of 25 ng/mL, with an estimated limit of quantification of 2.5 ng/mL, and an adequate combined standard uncertainty of 11.4%. Considering that all reagents are commercially available, the proposed strategy is feasible to be included on routine sample preparation. Monitoring urinary cobalt concentrations globally opens the perspective to support the anti-doping system to define a suitable threshold value and to understand its potential misuse by athletes seeking for performance improvement.

[ABSTRACT]. Objective. To measure the impact of the COVID-19 pandemic on the implementation of a program for timely detection, brief intervention, and referral for treatment of alcohol consumption in health centers at the first level of care in Mexico City. Methods. The data were collected at 18 health centers in Mexico City between 2019 and 2021, as part of a lar- ger study. A total of 287 participating health professionals measured their patients' alcohol consumption using the AUDIT-C test. The patients' demographic aspects and consumption patterns were analyzed, as well as care actions (detection, brief intervention, provision of leaflets, monitoring, and referral) at three points in time: before the COVID-19 pandemic, during confinement, and after confinement. Parametric and nonparametric tests were performed to identify the relationship and differences between the variables at the three points. Results. A total of 9090 people who consumed alcohol were identified; detection of consumption fluctuated in the three periods studied (26%, 53%, and 37%, respectively). Medium- and high-risk consumption was more frequent among young men with higher schooling during and after confinement. In the post-confinement period, monitoring and referral actions increased. Conclusions. Measuring the impact of the pandemic on the implementation of a program for timely detection of alcohol consumption, brief intervention, and referral for treatment in health centers helps to develop health policies by age, gender, schooling, and type of consumption at the first level of care.

RESUMEN

Abstract Cannabis sativa L. is one of the most consumed drugs in the world and recent studies have associated its use with an increase in the number of traffic accidents in different countries. In many countries, like Brazil, simple and reliable methodologies are still needed for the detection of drugs on site, mainly cannabinoids, considering its prevalence of use and oral fluid (OF) has been proved as an appropriate biological matrix for this purpose. Considering that, this work aims to review previous studies on immunochromatographic devices for on-site detection of cannabinoids in OF, discussing their sensitivity, specificity, cut-offs values and confirmatory methods. This data shows the importance of choosing a screening device and it reinforces the need for its implementation in Brazil. The research was conducted on 5 databases and all original articles, published in the last 10 years, were selected. A total of 32 articles were found, providing data for 17 screening devices of distinct brands. Only 2 screening devices showed satisfactory sensitivity and specificity in the evaluated studies (≥80% and ≥90% respectively). However, it should be considered that the screening devices still have some limitations, such as a higher cut-off than those recommended by international guidelines (cut-off > 2 ng/mL), therefore demonstrating the need for more studies in the area and the importance of confirmatory analysis usually fulfilled by LC-MS/MS, GC-MS/MS or GC-MS. Thus, the screening analyzes should not be evaluated by itself, but in association with confirmatory results and observational traits (behavioral changes), for a better understanding of the traffic scenario

RESUMEN

El consumo de Sustancias Psicoactivas (SPA) es una problemática que por años ha generado afectaciones en los ámbitos individual y colectivo, contribuyendo al aumento en las cifras de problemáticas psicosociales y de salud. El objetivo del estudio fue establecer la relación entre el bienestar psicológico y el consumo de SPA en 97 personas de 18 a 25 años del departamento del Quindío. Para ello, se implementó un diseño transversal con alcance correlacional. Los datos se recolectaron mediante la Prueba de Detección de Consumo de Alcohol, Tabaco y otras Sustancias y la Escala del Bienestar Psicológico de Ryff. Se identificó que la mayoría de los participantes se ubicaron en un nivel alto en la mayoría de las dimensiones de la escala de bienestar. El 91,75% de los participantes consumieron alguna sustancia, a lo largo de su vida. Finalmente, se encontró una relación entre la preocupación por otros por el consumo de tabaco y el bajo nivel de autonomía (-0,3144, p < 0,01), y el intento por dejar el consumo alcohol y bajo nivel del dominio del entorno (-0,3275, p < 0,01).

RESUMEN

La limitación del acceso a las bebidas alcohólicas recae parcialmente al margen del sector de la salud, pero debe introducirse con vistas a reducir la accesibilidad del alcohol, lo que redunda en menos consumo, menos daños y, por lo tanto, menos costos sanitarios y sociales. A pesar del uso generalizado de los sistemas de concesión de licencias, estos siguen sin utilizarse plenamente como herramienta de políticas, y las medidas solo se adoptan en parte o no se aplican. Es necesario aumentar la comprensión del público y de los encargados de formular políticas sobre su necesidad y valor, de modo que puedan promoverse e incluirse en los planes de políticas sobre el alcohol en todos los países. Esta hoja informativa describe qué implican, cómo deben construirse para que sean eficaces, cuál es su efecto y por qué deben introducirse.

RESUMEN

ABSTRACT: Clonazolam is a derivative of the Xanax active ingredient, alprazolam. Classified as a designer benzodiazepine, clonazolam availability has been rising because of its circulation on illegal internet drug markets and marginal cost in comparison to its parent analogs. Clonazolam's accessibility encourages abuse prevalence and use of designer benzodiazepines. In our case, a 14-year-old male was found unresponsive the morning after ingesting multiple tablets believed to be Xanax. Toxicology testing indicated 140 ng/mL of 8-aminoclonazolam, a clonazolam metabolite, in the decedent's system. Alprazolam was not identified. Pathological analysis determined cerebral and respiratory depression to be the mechanism of death, resulting from acute clonazolam intoxication. This case presents the first death induced by clonazolam alone. Current literature identifies a gap in designer benzodiazepine confirmatory testing and a lack of awareness within the forensic and medical communities. Knowledge of designer benzodiazepines is needed to better understand their potency and to help prevent future intoxications. We present this case to aid in the recognition of novel benzodiazepines by medical examiners and coroners, to encourage their consideration in suspected Xanax and other substance related investigations, and to be aware of the capabilities of toxicological testing to improve novel benzodiazepine identification and subsequent interpretation.

RESUMEN

Limiting the access to alcoholic beverages fall partially outside the health sector but they need to be implemented in order to reduce alcohol accessibility, leading to less alcohol consumption, harms, and therefore the health and social costs of alcohol. Despite the widespread use of licensing systems, they continue to be underused as a policy tool, and measures are only partially adopted and are not enforced. It is important to increase public and policy makers understanding of their need and value, so they can be promoted and included in alcohol policy plans in all countries. This fact sheet will describe what they include, how they need to be done to be effective, what is their impact and why they need to be implemented.
