Temporal variability and ecological risks of pharmaceuticals and cocaine during the Christmas and New Year holidays in a beach area of North Coast of São Paulo, Brazil.

This study assessed the occurrence and ecological potential risk of nine selected pharmaceuticals in water samples from the Juquehy River. The river flows continuously to Juquehy Beach, known as "the jewel of the north coast" of São Paulo, Brazil. Samples were collected during Christmas and the New Year (period of December 2023-January 2024), in addition to a previous baseline weekend, to compare the loads during "celebratory parties" versus "normal operational conditions." The findings indicated that the "mass gathering" during Christmas and New Year holidays contributed significantly to an increase of the mass load of the nine pharmaceuticals flowing along to the Juquehy River, i.e., caffeine (14.40-633.00 ng/L) > losartan ( furosemide (< LOQ to 9.16 ng/L) > diclofenac (0.61-4.55 ng/L) > carbamazepine (< LOQ to 0.73 ng/L) > orphenadrine (< LOQ to 0.11 ng/L) showed higher concentrations during the New Year holiday. Conversely, atenolol (< LOQ to 13.10 ng/L) > benzoylecgonine (0.33-7.23 ng/L) > cocaine (0.12-6.59 ng/L) showed higher concentrations during the Christmas day. The individual ecological risk assessment in the Juquehy River revealed a clear environmental concern for the aquatic ecosystem. The threat to the aquatic biota is significant, with caffeine and losartan presenting a moderate level of risk. Moreover, the mixture ecological risk assessment of nine compounds indicates acute moderate risks to algae, crustaceans, and fishes, as well as chronic low risks to fishes.

Applications of MALDI mass spectrometry in forensic science.

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.

"Cocaine Shark": First report on cocaine and benzoylecgonine detection in sharks.

Cocaine (COC) and benzoylecgonine (BE), the main COC metabolite, have been detected in aquatic ecosystems. Studies focusing on wild fish are, however, very limited, and no reports concerning elasmobranchs are available. This study investigated COC and BE levels in Brazilian Sharpnose sharks (Rhizoprionodon lalandii) (n = 13) using LC-MS/MS. All samples (13/13) tested positive for COC, with 92 % (12/13) testing positive for BE. COC concentrations (23.0 µg kg-1) were over 3-fold higher than BE (7.0 µg kg-1). COC levels were about three-fold significantly higher in muscle (33.8 ± 33.4 g kg-1) compared to liver (12.2 ± 14.2 µg kg-1). Females presented higher COC concentrations in muscle (40.2 ± 35.8 µg kg-1) compared to males (12.4 ± 5.9 µg kg-1). Several positive statistical correlations were noted between COC and BE (rho = 0.84) in females, indicating systemic COC transport and metabolization, as well as between BE and weight (rho = 0.62), and between COC and the Condition Factor (rho = 0.73). A strong correlation was noted between BE and COC in the muscle of non-pregnant females (rho = 1.00). This study represents the first COC and BE report in free-ranging sharks, and the findings point to the potential impacts of the presence of illicit drugs in environments.

Hard drugs use and tooth wear: a scoping review.

OBJECTIVES: This study aims to map evidence on the relationship between hard drug use and dental wear. The scoping review is guided by the question: What is the relationship between hard drug consumption and dental wear? MATERIALS AND METHODS: Adhering to PRISMA-ScR guidelines, searches were conducted across PubMed, Embase, and four databases in March 2024. Inclusion criteria included studies investigating the association between hard drug use and dental wear, regardless of publication date or language. Data were presented through narrative exposition, tables, and a conceptual framework. RESULTS: Twenty-eight studies (four case-control, three cross-sectional, five case reports, and sixteen literature reviews) were included. Among case-control studies, 75% observed an association between drug use and dental erosion; however, no cross-sectional studies demonstrated this association. Despite questionable quality, reviews established connections between drug use and dental erosion. Studies aimed to elucidate potential causes for dental erosion. CONCLUSIONS: Analysis suggests a potential link between hard drug use and dental wear, though indirect. Factors like bruxism and reduced salivary pH may contribute to dental wear among drug users. Further investigation through primary studies exploring this relationship is necessary. CLINICAL RELEVANCE: Dentists should focus not only on clinical characteristics of dental wear but also on mediating factors such as bruxism and decreased salivary pH associated with drug use. This holistic approach allows for a deeper understanding of dental wear mechanisms, enabling targeted preventive and therapeutic interventions.

Vivencias y estrategias comunitarias de manejo del riesgo dentro de las prácticas chemsex: un estudio cualitativo / Community experiences and strategies of risk management within chemsex practices: a qualitative study

Resumen El auge en el estudio del uso sexualizado de drogas entre hombres gais, bisexuales u otros hombres que tienen sexo con hombres (HSH), conocido como chemsex, ha generado una multiplicidad de datos que contribuyen a su problematización en tanto cuestión de salud pública a través del vínculo con el VIH y las adicciones. El estudio de estas prácticas, desde un paradigma biomédico, se ha centrado en el riesgo y ha contribuido a su reducción como fenómeno único y cuantificable. Este estudio tiene como objetivo explorar la vivencia del riesgo en el transcurso de las prácticas, para conocer qué estrategias de manejo emplean frente a éste y de qué manera son generadas. Se realizaron entrevistas semiestructuradas a cinco practicantes de chemsex en el Área Metropolitana de Barcelona y, posteriormente se aplicó un análisis temático. Los hallazgos muestran cómo estos hombres detectan, asumen y enfrentan los riesgos presentes en estas prácticas, donde toman relevancia el tipo de relaciones que allí se dan y el círculo social del que disponen. Este estudio destaca también la creación de estrategias basadas en la experiencia y cómo la transmisión de estos saberes entre participantes facilita la toma de decisiones y el manejo del riesgo.

Abstract The rise in the study of sexualised drug use among gay, bisexual and other men who have sex with men (MSM), known as chemsex, has generated a multiplicity of data that contribute to its problematisation as a public health issue through the link with HIV and addictions. The study of these practices, from a biomedical paradigm, has focused on risk and has contributed to its reduction as a unique and quantifiable phenomenon. This study aims to explore the experience of risk in the course of the practices, to find out what management strategies they employ in the face of risk and how they are generated. Semi-structured interviews were conducted with five chemsex practitioners in the Metropolitan Area of Barcelona and, subsequently, a thematic analysis was applied. The findings show how these men detect, assume and confront the risks present in these practices, where the type of relationships that take place and the social circle available to them are relevant. This study also highlights the creation of strategies based on experience and how the transmission of this knowledge among participants facilitates decision-making and risk management.

Análisis comparativo entre regiones del mundo relacionado con el consumo de sustancias psicoactivas en las últimas tres décadas / Comparative analysis between regions of the world related to the consumption of psychoactive substances in the last three decades

Resumen El consumo de sustancias psicoactivas (SPA) trae efectos de adicción que modifican el pensamiento, la mente y el espíritu del adicto, no solo está generando un riesgo latente que afecta la salud de las personas, también trae consecuencias negativas para la sociedad misma, como mayor inversión económica en salud, presencia de habitantes de calle, aumento de delincuencia, entre otros aspectos. El objetivo del presente estudio consistió en evaluar las estadísticas relacionadas con el consumo de sustancias psicoactivas a nivel mundial en las últimas tres décadas. Para el análisis de la información se utilizó la técnica multivariada de la varianza MANOVA con contraste canónica ortogonal, se empleó el paquete estadístico SAS University en el proceso de la información. Como resultado destacado, se encontró divergencia estadística entre regiones, donde Norteamérica ocupa el primer lugar seguido de Asia y Oceanía. El mayor número de muertes por trastornos relacionados por el consumo de SPA se da en personas menores a los 49 años. El acelerado incremento y abuso en el consumo de SPA está generando altos índices de morbilidad y mortalidad a nivel global. Es una prioridad actuar con urgencia desde todos los frentes, profesionales de la salud, líderes políticos y comunitarios, entes educativos y núcleo familiar, para controlar esta problemática y tratar de disminuir el consumo y abuso de SPA.

Abstract The consumption of psychoactive substances (PAS) has addictive effects that modify the addict's thinking, mind and spirit, and not only generates a latent risk that affects people's health, but also has negative consequences for society itself, such as greater economic investment in health, the presence of street dwellers, and an increase in crime, among other aspects. The objective of this study was to evaluate the statistics related to the consumption of psychoactive substances worldwide in the last three decades. For the analysis of the information, the multivariate technique of variance MANOVA with orthogonal canonical contrast was used, and the SAS University statistical package was used to process the information. As an outstanding result, statistical divergence was found between regions, with North America occupying the first place followed by Asia and Oceania. The highest number of deaths due to disorders related to PAS consumption occurs in people under 49 years of age. The accelerated increase and abuse of PAS is generating high rates of morbidity and mortality globally. It is a priority to act urgently from all fronts, health professionals, political and community leaders, educational entities and the family nucleus, to control this problem and try to reduce the consumption and abuse of PAS.

Relationship between psychoactive substance, alcohol and cigarette use in nursing students. A cross-sectional study.

BACKGROUND: The increase in the use of psychoactive substances, alcohol and cigarettes in young people has become a public health problem. The identification of factors that increase or reduce the risk of exposure to these substances and the possible relationship between them is essential for planning strategies with a risk approach; hence the reason for this study. The objective was to establish the profile of use of psychoactive substances, alcohol and cigarettes and the factors associated with such use in nursing students of a higher education institution. METHODS: Quantitative, observational, analytical cross-sectional study. RESULTS: We included 310 students from 1 st to 9th semester of a Nursing programme from a private higher education institution in Bogotá. The prevalence of psychoactive substance use in the last year was 2.96% (95%CI, 1.36-5.54), with marijuana being the substance most used (55.55%). The prevalence of alcohol and cigarette use during the last 12 months was estimated at 86.64% (95%CI, 83.24-91.0) and 12.16% (95%CI, 8.43-15.88) respectively. A statistically significant association was found between the use of these substances: alcohol use was associated with cigarette use (OR = 3.22; P = 0.006) and smoking was associated with psychoactive substance use (OR = 15.4; P < 0.001). CONCLUSIONS: Alcohol use increases the likelihood of smoking cigarettes, and this in turn increases the likelihood of psychoactive substance use, in this university population.

Self-reported neurostimulant use among university students in Santa Maria, Rio Grande do Sul, Brazil.

University students frequently resort to psychostimulants to enhance their physical and mental performance and manage academic pressures. However, these substances can lead to dependence and other undesired symptoms, and little empirical data are available for relevant stakeholders, raising significant concerns in health care. Therefore, this study aims to characterize neurostimulant use among university students in Rio Grande do Sul, Brazil. We collected from 880 students' data using anonymous self-administration. The questionnaire included consumption patterns of caffeine, nicotine, ecstasy, methamphetamine, "merla" (coca base), methylphenidate, cocaine, crack, and ketamine. Additionally, participants shared information on demographic and socioeconomic factors. Use of at least one neurostimulant was reported by89.2% of the participants. Among nonusers, the most frequently cited reason was "previous information about harmful effects of these drugs." Caffeine, followed by nicotine, ecstasy, and methylphenidate were the most consumed substances, with main reasons being "improving academic performance" and "recreation." Women more often consumed caffeine (72.7%), while other psychostimulants were more consumed by men (42.2%) and individuals of other genders (0.5%). Students who consumed other substances had higher family incomes than that of families of caffeine users. In addition, 60.4% of caffeine users resided with family members, whereas 63.3% of users of other substances did not. Our findings can offer essential data on the reasons and symptoms associated with the use of neurostimulants among university students. This information could aid in raising awareness among students, universities, and health-care agencies about this often-neglected subject.

A compact Fourier-transform near-infrared spectrophotometer and chemometrics for characterizing a comprehensive set of seized ecstasy samples.

A comprehensive data set of ecstasy samples containing MDMA (N-methyl-3,4-methylenedioxyamphetamine) and MDA (3,4-methylenedioxyamphetamine) seized by the Brazilian Federal Police was characterized using spectral data obtained by a compact, low-cost, near-infrared Fourier-transform based spectrophotometer. Qualitative and quantitative characterization was accomplished using soft independent modeling of class analogy (SIMCA), linear discriminant analysis (LDA) classification, discriminating partial least square (PLS-DA), and regression models based on partial least square (PLS). By applying chemometric analysis, a protocol can be proposed for the in-field screening of seized ecstasy samples. The validation led to an efficiency superior to 96 % for ecstasy classification and estimating total actives, MDMA, and MDA content in the samples with a root mean square error of validation of 4.4, 4.2, and 2.7 % (m/m), respectively. The feasibility and drawbacks of the NIR technology applied to ecstasy characterization and the compromise between false positives and false negatives rate achieved by the classification models are discussed and a new approach to improve the classification robustness was proposed considering the forensic context.

Wastewater surveillance to assess cocaine and methylenedioxymethamphetamine use trends during a major music festival in Brazil.

Wastewater-based epidemiology was applied in northeastern Brazil during a dance festival, revealing that cocaine consumption doubled during the event days. The daily drug loads were 0.95 ± 0.03 to 11.4 ± 0.4 g/day for BE, 1.8 ± 0.4 to 7.6 ± 0.3 g/day for COC, 0.04 ± 0.02 to 0.19 ± 0.02 g/day for COE, and 0.08 ± 0.02 to 0.80 ± 0.02 g/day for MDMA.

This study employed the wastewater­based epidemiology (WBE) strategy to investigate cocaine (COC) and ecstasy (MDMA) usage during Carnatal festival in Rio Grande do Norte, Brazil. Wastewater samples were collected over the four festival days (December 12­15, 2019), as well as during corresponding days before and after the event. The samples underwent filtration, acidification, solid­phase extraction (SPE) for pre­concentration, and analysis using ultra­high­performance liquid chromatography­tandem mass spectrometry (UHPLC­MS/MS) with calibration using deuterated internal standards. The measured concentration ranges in the wastewater samples were as follows: benzoylecgonine (BE, a metabolite of COC use) ranged from 760 ± 30 to 8914 ± 252 ng/L, COC (non­metabolized or directly discharged) ranged from 1182 ± 25 to 6,760 ± 95 ng/L, cocaethylene (COE, a metabolite of alcohol­COC use) ranged from 21 ± 10 to 161 ± 10 ng/L, and MDMA (ecstasy) ranged from 18 ± 5 to 613 ± 15 ng/L. Daily wastewater loads were estimated as 0.81 ± 0.03 to 11.69 ± 0.33 g/day for BE, 1.42 ± 0.03 to 8.06 ± 0.11 g/day for COC, 0.02 ± 0.01 to 0.21 ± 0.01 g/day for COE, and 0.02 ± 0.01 to 0.80 ± 0.02 g/day for MDMA. Notably, COE and MDMA were only detected above the quantification limit during the festival days. The data enable estimating that COC consumption doubled during the event days. The COC/BE ratio indicated likely drug disposals on the event's last day and the subsequent week. The study's findings shed light on illicit substance consumption, assisting in public health programs and combating drug trafficking efforts.

Relación entre el consumo de sustancias psicoactivas, alcohol y cigarrillo en estudiantes de Enfermería. Un estudio de corte transversal / Relationship Between Psychoactive Substance, Alcohol and Cigarette use in Nursing Students. A Cross-Sectional Study

RESUMEN Introducción: El incremento del consumo de sustancias psicoactivas (SPA), alcohol y cigarrillo en población joven se ha convertido en un problema de salud pública. La identificación de los factores que aumentan o disminuyen el riesgo de la exposición a estas sustancias y la relación que puede haber entre ellas resulta fundamental para la planificación de estrategias con enfoque de riesgo, razón por la cual se planteó el presente estudio. El objetivo es establecer el perfil de consumo de SPA, alcohol y cigarrillo y los factores asociados con dicho consumo en estudiantes del programa de Enfermería de una institución de educación superior. Métodos: Estudio cuantitativo, observacional y analítico de tipo corte transversal. Resultados: Se incluyó a 310 estudiantes de los semestres I a IX de un programa de Enfermería de una institución privada de educación superior de Bogotá. La prevalencia de consumo de SPA en el último ario fue del 2,96% (IC95%, 1,36-5,54); la marihuana es la sustancia de mayor consumo (55,55%). Las prevalencias de consumo de alcohol y cigarrillo durante los últimos 12 meses se estimaron en el 86,64% (IC95%, 83,24-91,0) y el 12,16% (IC95%, 8,4315,88) respectivamente. Se encontró una asociación estadísticamente significativa entre los consumos: tomar alcohol se asoció con el consumo de cigarrillo (OR = 3,22; p = 0,006) y fumar se asoció con el consumo de SPA (OR = 15,4; p <0,001). Conclusiones: En esta población universitaria, el consumo de alcohol aumenta la posibilidad de consumo de cigarrillo, y este a su vez aumenta la posibilidad del consumo de SPA.

Asociación del consumo de drogas ilícitas en mujeres embarazadas y sífilis congénita en un Hospital Público de México / Association of illicit drug use in pregnant women and congenital syphilis in a public hospital in Mexico

Resumen Realizamos un estudio de casos y controles anidado en una cohorte con el objetivo de estudiar la asociación del consumo de drogas ilícitas y sífilis congénita (SC). Los casos se diagnosticaron mediante pruebas treponémicas y no treponémicas en la madre y el recién nacido (RN). Se realizó un análisis multivariado con regresión logística. Se registraron 6.171 nacimientos con edad gestacional promedio 37,8 semanas y se diagnosticaron 62 eventos de SC (incidencia: 10,5 eventos/1.000 RN). Los factores maternos asociados fueron el uso de drogas ilícitas (OR = 14,08; IC 95% = 1,19-166,6), menos de cinco consultas en el control prenatal (OR = 2,9; IC 95% = 1,12-7,53), más de dos parejas sexuales (OR = 3,76; IC 95% = 1,62-8,71) y estudios universitarios (OR = 0,06; IC 95% = 0,005-0,85). Entre las madres de los casos, la prevalencia del consumo de drogas ilícitas fue de 22,6% y las más frecuentes fueron las metanfetaminas y la marihuana.

Abstract We conducted a nested case-control study within a cohort with the aim of studying the association between illicit drug use and congenital syphilis (CS). Cases were diagnosed based on treponemal and non-treponemal tests conducted both in the mother and the newborn (NB). Multivariate analysis with logistic regression was performed. A total of 6171 births with a mean gestational age of 37.8 weeks were recorded and 62 CS events were diagnosed (incidence 10.5 events/1000 NB). Associated maternal factors were illicit drug use (OR 14.08, 95% CI 1.19-166.6), <5 prenatal visits (OR 2.9, 95% CI 1.12-7.53), more than two sexual partners (OR 3.76, 95% CI 1.62-8.71) and professional education level (OR 0.06, 95% CI 0.005-0.85). Among the mothers of the cases presented, the prevalence of illicit drug use was 22.6% and the most frequent drugs were methamphetamines and cannabis.

O uso de drogas e seus efeitos na cavidade oral

Objetivos: Descrever as principais manifestações bucais associadas ao uso das drogas lícitas e ilícitas mais utilizadas atualmente, bem como os cuidados que devem ser tomados durante o atendimento odontológico desses pacientes. Revisão de literatura: Na revisão foi abordada a classificação das substâncias químicas, as principais manifestações orais e os cuidados que o cirurgião-dentista deve ter durante o atendimento odontológico. As substâncias descritas foram álcool, tabaco, benzodiazepínicos, maconha, anfetaminas e cocaína/crack. As complicações de saúde bucal associadas ao abuso de drogas podem resultar da exposição direta dos tecidos orais às drogas durante o fumo ou ingestão, da interação biológica das drogas com a fisiologia normal da cavidade oral e dos efeitos das drogas na função cerebral que resultam em um espectro de comportamentos de dependência, como comportamento de risco, falta de higiene e descuido. Considerações finais: O consumo de substâncias psicoativas, seja a curto ou longo prazo, pode desencadear consequências, tanto na saúde geral como na saúde bucal do usuário. Sob essa perspectiva, o cirurgião-dentista deve estar ciente das manifestações orais e sistêmicas causadas pelas substâncias psicoativas e estar capacitado para diagnosticar, tratar ou também encaminhar o usuário, se necessário, visando um cuidado integral e multiprofissional.

Objective: to describe the main oral manifestations associated with the use of the most commonly used licit and illicit drugs today, as well as the care that should be taken during the dental care of these patients. Literature review: The review covered the classification of chemical substances, the main oral manifestations and the care that dentist should take during dental care. The substances described were alcohol, tobacco, benzodiazepines, marijuana, amphetamines and cocaine/crack. Oral health complications associated with drug abuse can result from direct exposure of oral tissues to drugs during smoking or ingestion, from the biological interaction of drugs with the normal physiology of the oral cavity, and from the effects of drugs on brain function that result in a spectrum of addictive behaviors, such as risk behavior, poor hygiene and carelessness. Final considerations: The consumption of psychoactive substances, whether in the short or long term, can have consequences for both the general health and the oral health of the user. From this perspective, the dentist must be aware of the oral and systemic manifestations caused by psychoactive substances and be able to diagnose, treat or also refer the user, if necessary, aiming for comprehensive, multi-professional care.

Association between religiosity/spirituality and substance use among homeless individuals.

BACKGROUND: Alcohol and illicit drug use are prevalent among homeless people. Religiosity and spirituality (RS) have been widely associated with lower consumption of substances. However, evidence of this relationship among homeless people is still scarce. AIMS: To evaluate the associations between RS and alcohol and illicit drug consumption among homeless people in a large Brazilian urban center. METHOD: This cross-sectional study was carried out in São Paulo city, Brazil. Aspects such as spirituality (FACIT-Sp12), religiosity (DUREL), spiritual-religious coping (Brief-RCOPE), and self-report questions concerning the current substance use (alcohol and illicit substances) were evaluated. Adjusted logistic regression models were used to assess the impact of RS beliefs on alcohol and illicit drug consumption. RESULTS: A total of 456 homeless people were included, of an average age of 44.5 (SD = 12.6) years. More than half of the participants consumed alcohol (55.7%) weekly and 34.2% used illicit drugs weekly. Adjusted logistic regression models identified that aspects of RS were associated with lower likelihood factors for alcohol and illicit drug use; conversely, negative spiritual religious coping (SRC) strategies were associated with a higher likelihood to use both. CONCLUSION: The prevalence of alcohol and illicit drug use among participants was high. RS and positive SRC were important protective factors for lower consumption of these substances. Conversely, negative SRC strategies were associated with risk factors.

Impact of licit and illicit substances on the oral health-related quality of life in adolescents.

OBJECTIVE: To assess the impact of the consumption of licit and illicit substances on the oral health-related quality of life (OHRQoL) of adolescents from public schools in the south of Brazil. METHODS: This cross-sectional study was carried out with a random sample of adolescents aged between 17 and 18 years old from Santa Maria, Brazil. The consumption of licit and illicit substances was measured through a self-administered questionnaire with questions from the National Survey of Scholar Health. The OHRQoL was collected using the Brazilian short version of Child Perceptions Questionnaire 11-14 (CPQ11-14). Multilevel Poisson regression models were used to estimate the association between the outcome and the explanatory variables where the adolescents (first level) were nested in their schools (second level). RESULTS: A total of 768 adolescents were evaluated. Of these, about 15.6% have already used illegal substances. Adolescents who reported the use of illicit substances had 28% higher CPQ11-14 scores when compared to their counterparts. Alcohol use was also related to worse levels of OHRQoL, while the consumption of cigarettes acted as a protective factor. CONCLUSIONS: This study found an association between the use of alcohol and illicit drugs with worse levels of OHRQoL.

Fatores associados ao policonsumo de álcool, tabaco e drogas ilícitas: Pesquisa Nacional de Saúde do Escolar 2019 / Factors associated with concurrent alcohol, tobacco and illicit drug use: 2019 National School-Based Health Survey

Resumo Objetivou-se analisar os fatores associados ao policonsumo de álcool, tabaco e drogas ilícitas, entre adolescentes escolares brasileiros de 13 a 17 anos. Estudo transversal, com dados da Pesquisa Nacional de Saúde do Escolar (2019). A variável desfecho foi o relato de consumo das três substâncias nos últimos 30 dias. As variáveis independentes foram agrupadas em quatro blocos: características sociodemográficas; contexto familiar; situações estressoras; aspectos comportamentais. Foi realizada análise de regressão logística múltipla hierarquizada, permanecendo no modelo final as variáveis com p<0,05. A prevalência de policonsumo em adolescentes escolares foi 3,3%. No modelo final, sexo masculino, morar na região Centro-Oeste, Sul e Sudeste, faltar a escola sem permissão, pais não saberem o que fazem no tempo livre, ter pais fumantes, sofrer agressão física pelos pais, sentir que a vida não vale a pena ser vivida, experimentar bebida alcoólica e drogas ilícitas antes dos 13 anos, ter amigos que bebem bebida alcoólica, fumam e usam drogas na sua presença permaneceram associados ao desfecho. Os dados mostram alta prevalência de policonsumo de três substâncias entre adolescentes e sua associação a fatores sociodemográficos, familiares, comportamentais e a eventos estressantes.

Abstract The aim of this study was to analyze the factors associated with concurrent alcohol, tobacco and illicit drug use among Brazilian schoolchildren aged 13-17. We conducted a cross-sectional study using data from the 2019 National School-Based Health Survey. The outcome was use of the three substances during the last 30 days. Hierarchical multiple logistic regression was carried out with independent variables grouped into four blocks: sociodemographic characteristics; family context; behavioral aspects; and stressors. Variables with p<0.05 were retained in the final model. The prevalence of concurrent substance use was 3.3%. Being male, living in the Midwest, South and Southeast, skipping school without parent permission, parents not knowing what their children do in their free time, having parents who smoke, having experienced physical aggression from parents, feeling that life is not worth living, trying drinking and illicit drugs before the age of 13, and having friends who drink alcohol, smoke and use drugs in their presence remained associated with the outcome in the final model. The findings reveal high prevalence of concurrent alcohol, cigarette and illicit drug use among adolescents and that poly use is associated with sociodemographic, family, and behavioral factors and stressors.

Multiple substance use and associated factors in transgender women and travestis: findings from the TransOdara Study, Brazil / Uso de múltiplas substâncias e fatores associados em mulheres trans e travestis: resultados do estudo TransOdara, Brasil

ABSTRACT Objective To estimate the prevalence of concomitant substance consumption and analyze associated risk factors in a non-probabilistic sample of the Brazilian population of transgender women and travestis. Methods A cross-sectional study was conducted with recruitment via respondent-driven sampling. The sample included transgender women and travestis residing in São Paulo, Porto Alegre, Salvador, Manaus, and Campo Grande, aged 18 years or older, between 2019 and 2021. The outcome was the concomitant use of licit and illicit substances. The association between sociodemographic/behavioral factors and the outcome was analyzed through Poisson regression with mixed effects. Adjusted prevalence ratios (confidence interval of 95% — 95%CI) were estimated. Results The prevalence in the last 12 months of multiple substance use was 49.3%, of which 65.5% were alcohol, 52.9% tobacco, and 40.1% marijuana. Transgender women and travestis who use multiple substances face more violence (1.71; 95%CI 1.14-2.55), unemployment (1.58; 95%CI 1.05-2.37) and pervasive unstable work status (1.52; 95%CI 1.08-2.14), transactional sex (1.51; 95%CI 1.21-1.88) which can be their sole option to make a living, and are aged 18 to 24 years (1.37; 95%CI 1.14-1.65). Conclusion The use of multiple substances may be an attempt to cope with distress and marginalization. Substance use has been associated with multiple harms and medical conditions. Comprehensive management and care should be provided, as defined by the key principles of the Brazilian Unified Health System. Health care should be integrated into structural interventions.

RESUMO Objetivo Estimar a prevalência do consumo concomitante de substâncias e analisar fatores de risco associados em uma amostra não probabilística da população brasileira de mulheres trans e travestis. Métodos Estudo transversal, com recrutamento por meio da metodologia respondent-driven sampling. A amostra incluiu mulheres trans e travestis residentes em São Paulo, Porto Alegre, Salvador, Manaus e Campo Grande, maiores de 18 anos, entre 2019 e 2021. O desfecho foi o uso concomitante de substâncias lícitas e ilícitas. A associação entre fatores sociodemográficos/comportamentais e o desfecho foi analisada com regressão de Poisson com efeitos mistos, estimando-se razões de prevalência ajustadas (intervalo de confiança de 95% - IC95%). Resultados A prevalência nos últimos 12 meses de uso de múltiplas substâncias foi de 49,3%, sendo 65,5% álcool, 52,9% tabaco e 40,1% maconha. Mulheres trans e travestis que usam múltiplas substâncias enfrentam mais violência (1,71; IC95% 1,14-2,55), desemprego (1,58; IC95% 1,05-2,37) e trabalho instável (1,52; IC95% 1,08-2,14), sexo transacional (1,51; IC95% 1,21-1,88), que pode ser a única opção de sustento, e têm de 18 a 24 anos (1,37; IC95% 1,14-1,65). Conclusão O uso de múltiplas substâncias pode ser uma tentativa de lidar com o sofrimento e a marginalização. O uso de substâncias tem sido associado a múltiplos danos e condições médicas. Uma gestão integral e cuidados abrangentes devem ser providenciados, conforme definido pelos princípios-chave do Sistema Único de Saúde do Brasil. Os cuidados de saúde devem ser integrados em intervenções estruturais.

Drogas na gestação em pré-natal de baixo risco e fatores associados / Drogas en embarazos en controles prenatales de bajo riesgo y factores asociados / Drugs during pregnancy in low-risk prenatal care and associated factors

Resumo Objetivo Identificar a prevalência do uso de drogas lícitas e ilícitas por gestantes que realizavam pré-natal na Atenção Primária à Saúde e fatores associados ao seu uso. Métodos Estudo transversal realizado por meio de roteiro estruturado, composto de variáveis sociodemográficas gestacionais e uso de drogas pela gestante e seus familiares, aplicado a 270 mulheres em pré-natal de baixo risco de 15 Unidades Básicas de Saúde, de dois municípios de uma região metropolitana do Sul do Brasil, onde existem diferenças socioeconômicas e demográficas negativas em relação a cidade-polo. A coleta de dados ocorreu no período de dezembro de 2019 a fevereiro de 2020. Os dados foram analisados por meio do teste do qui-quadrado de Pearson, sendo consideradas significativas as associações com valor de p<0,05. Resultados Jovens de 25 a 35 anos corresponderam a 77% da amostra; pardas/negras foram 60,4%; multigestas somaram 41,8% (com mais de três filhos). Tinham parceiro conjugal fixo 86,6%. A prevalência de uso atual de drogas foi de 46,2%. Houve associação estatisticamente significativa entre consumo de álcool e ter tido intercorrências gestacionais (razão de chance de 2,5; intervalo de confiança de 1,17-5,22); entre o consumo de maconha e a idade de 15 a 19 anos (razão de chance de 2,7; intervalo de confiança de 1,01- 7,03); entre consumo de tabaco e uso de drogas pelo esposo (razão de chance de 4,1; intervalo de confiança de 1,75- 9,55) e entre uso de tabaco e classificação familiar do tipo monoparental (razão de chance de 6,6; intervalo de confiança de 1,55 - 28,43). Conclusão A prevalência entre uso atual e uso na vida foi elevada. As gestantes eram multigestas em pré-natal de baixo risco. O uso de drogas esteve associado a intercorrências gestacionais, idade, uso de drogas pelo esposo e a classificação familiar do tipo monoparental.

Resumen Objetivo Identificar la prevalencia del consumo de drogas lícitas e ilícitas por mujeres embarazadas que realizaban control prenatal en la Atención Primaria de Salud y factores asociados a su uso.

Abstract Objective To identify the prevalence of the use of legal and illicit drugs by pregnant women who received prenatal care in Primary Health Care and factors associated with their usage. Methods Cross-sectional study carried out using a structured script, composed of gestational sociodemographic variables and drug use by pregnant women and their families, applied to 270 women undergoing low-risk prenatal care at 15 Basic Health Units, in two municipalities in a metropolitan region of Southern Brazil, where there are negative socioeconomic and demographic differences in relation to the hub city. Data collection took place from December 2019 to February 2020. Data were analyzed using Pearson's chi-square test, with associations with a value of p<0.05 being considered significant. Results Young people aged 25 to 35 accounted for 77% of the sample; brown/black were 60.4%; multigravidae accounted for 41.8% (with more than three children). 86.6% had a steady marital partner. The prevalence of current drug use was 46.2%. There was a statistically significant association between alcohol consumption and having had pregnancy complications (odds ratio of 2.5; confidence interval of 1.17-5.22); between marijuana consumption and the age of 15 to 19 years (odds ratio of 2.7; confidence interval of 1.01-7.03); between tobacco consumption and drug use by the husband (odds ratio of 4.1; confidence interval of 1.75-9.55) and between tobacco use and single-parent family classification (odds ratio of 6.6 ; confidence interval 1.55 - 28.43). Conclusion The prevalence between current usage and lifetime use was high. The multipregnancies in women were undergoing low-risk prenatal care. Drug use, age, drug use by the husband and single-parent family classification were associated with gestational complications.

Transtorno do espectro do autismo e o uso materno e paterno de medicamentos, tabaco, álcool e drogas ilícitas / Maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder

Resumo O presente estudo objetivou investigar a associação entre o TEA e o uso materno e paterno de medicamentos, tabaco, álcool e drogas ilícitas. Trata-se de um estudo caso-controle realizado com crianças e adolescentes diagnosticados com TEA e indivíduos neurotípicos. Os dados foram colhidos por meio de entrevista com as mães ou responsáveis. Foram analisadas as variáveis sexo e idade das crianças/adolescentes; idade dos pais; uso de medicamentos antes e durante a gestação; classes de medicamentos usados na gestação; tabagismo materno e paterno; etilismo materno e paterno; uso de drogas ilícitas pelos pais. Para a análise das informações, utilizou-se o modelo de regressão logística, além da razão de chances (OR) bruta e ajustada. Os resultados mostraram que, após os ajustes, foi encontrada associação entre o uso materno na gestação de antitérmicos/analgésicos (OR = 2,26; IC95% 1,29-3,95; p < 0,040) com o TEA. Já o uso de tabaco, álcool e drogas ilícitas materno e paterno, antes e durante a gestação, não apontou relação com o TEA. Os dados encontrados sugerem que existe influência de fatores ambientais no desenvolvimento do TEA.

Abstract The aim of this study was to investigate the association between maternal and paternal licit and illicit drug use, smoking and drinking and autism spectrum disorder (ASD). We conducted a case-control study with children and adolescents diagnosed with ASD and neurotypical individuals. The data were collected using a semi-structured questionnaire administered during interviews with the children's mothers or guardians. The following variables were analyzed: child sex and age; maternal and parental age; use of medicines before and during pregnancy; classes of medicines used during pregnancy; maternal and paternal smoking; maternal and paternal drinking; maternal and paternal illicit drug use. The data were analyzed using logistic regression and crude and adjusted odds ratios (OR). After adjustment, the results showed an association between maternal use of antipyretics/pain killers during pregnancy (OR = 2.26; 95%CI 1.29-3.95; p < 0.040) and ASD. No association was found between maternal and paternal smoking, drinking and illicit drug use before and during pregnancy and ASD. The findings suggest that the development of ASD is influenced by environmental factors.
