O consumo indiscriminado de substâncias químicas que melhoram o desempenho no esporte se tornou motivo de preocupação ao colocar o bem-estar e a vida do atleta em risco. Considerando a relevância do entendimento dos determinantes que conduzem os indivíduos à utilização de compostos químicos com propriedades ergogênicas, o propósito desta pesquisa consistiu em avaliar a prevalência e as características associadas ao uso de substâncias químicas para aprimoramento esportivo entre os estudantes universitários matriculados no Curso de Educação Física de uma instituição de Ensino Superior pública. A amostra do presente estudo foi composta por 230 participantes, os quais foram submetidos a um questionário, embasado em artigos científicos que abordam a prevalência e a utilização de suplementos e anabolizantes. Verificou-se que os suplementos mais frequentemente adotados foram aqueles contendo proteínas e aminoácidos como componentes principais, enquanto os esteroides anabólicos androgênicos são os anabolizantes mais usados. A prescrição mais citada para o uso de suplementos e anabolizantes foi por indicação própria. Foi relatada a presença de efeitos colaterais advindos do uso das substâncias químicas. A regressão logística com as variáveis independentes mostrou associação entre a utilização de suplementos com as variáveis: sexo OR= 2,4 (IC95%: 1,4 - 4,4), tipo de graduação OR= 2,6 (IC95%: 1,4 - 4,8) e idade OR= 3,1 (IC95%: 1,4 - 7,0). O consumo desses produtos, de forma indiscriminada, aponta a necessidade de alertar a população quanto aos riscos à saúde, de maneira que se fazem necessários mais estudos na área.

The uses of natural compounds, such as essential oils (EOs), are limited due to their instability to light, oxygen and temperature, factors that affect their application. Therefore, improving stability becomes necessary. The objective of this study was to prepare inclusion complexes of Litsea cubeba essential oil (LCEO) with β-cyclodextrin (β-CD) using physical mixing (PM), kneading (KN) and co-precipitation (CP) methods and to evaluate the efficiency of the complexes and their physicochemical properties using ATR-FTIR, FT-Raman, DSC and TG. The study also assessed cytotoxicity against human colorectal and cervical cancer cells and antifungal activity against Aspergillus flavus and Fusarium verticillioides. The complexation efficiency results presented significant evidence of LCEO:β-CD inclusion complex formation, with KN (83%) and CP (73%) being the best methods used in this study. All tested LCEO:β-CD inclusion complexes exhibited toxicity to HT-29 cells. Although the cytotoxic effect was less pronounced in HeLa tumor cells, LCEO-KN was more active against Hela than non-tumor cells. LCEO-KN and LCEO-CP inclusion complexes were efficient against both toxigenic fungi, A. flavus and F. verticillioides. Therefore, the molecular inclusion of LCEO into β-CD was successful, as well as the preliminary biological results, evidencing that the β-CD inclusion process may be a viable alternative to facilitate and increase future applications of this EO as therapeutic medication, food additive and natural antifungal agent.

This study aimed to investigate a miniaturized extraction methodology with analysis by GC-MS for simultaneous detection and quantification of cocaine (COC), benzoylecgonine (BZE) and cocaethylene (CE) in hair to monitor drug addicts. The process was done following the international guide of the Scientific Task Force on Forensic Toxicology. After sample extraction, derivatizing solution was added, clean-up was done by the Hollow Fiber Liquid Phase Microextraction (HF-LPME) and adapted to use the ultrasonic bath, a simple and easy-to-handle device. Isobutylchloroformate was first used as derivatization reagent to convert benzoylecgonine to isobutylbenzoylecgonine. Analytes quantification occurred within a linear range of 0.1 to 20 ng mg-1 for COC and 0.05 to 5 ng mg-1 for BZE and CE, with a correlation coefficient of r > 0.99. Limits of detection were 0.05; 0.03 and 0.03 ng mg-1, whereas limits of quantification were 0.1; 0.05 and 0.05 ng mg-1 for COC; BZE and CE, respectively. There was no matrix effect interference. Intra and inter-day precision and accuracy were acceptable according to international guidelines. The analytical method HF-LPME-GC-MS was successfully applied to 14 hair samples from patients admitted in drugs detoxification programs. All samples resulted positive for cocaine (0.80-> 20 ng mg-1) and benzoylecgonine (0.20-> 5 ng mg-1), 11 samples were positive for cocaethylene (0.10-> 0.60 ng mg-1).

Objective: To analyze the data on epidemiological records of autointoxication reports registered at a toxicological assistance center. Methods: Exploratory, descriptive, and retrospective study with the analysis of secondary data, conducted from the audit on Toxicological Occurrence Notification and Attendance forms, referring to the period from 2014 to 2018, filed in a toxicological information and assistance center, located in a municipality in southern Brazil. The data obtained were compiled in spreadsheets and analyzed using simple descriptive statistics. Results: 2,942 epidemiological records on women's autointoxication were audited, 72.0% of the total cases in the period studied. The predominant age group was 18 to 29 years old, with 1697 (57.7%) cases. The main toxic agent was medication, and the only agent of intoxication in 2,358 cases (80.1%). Psychotropic drugs accounted for 55.2% (1,593) of the cases, mainly antiepileptic and psychoanalytic drugs. Clonazepam was present in 567 (35.6%) suicide attempts and as the sole agent in 275 (17.3%) of them. In 873 cases (54.8%), mental illness was reported, in 546 (34.3%) previous suicide attempts, and 1,082 (67.9%) continued use of psychotropic medication. The main outcome was hospital discharge in 1,239 cases (77.8%). Conclusion: The study showed an increase in cases of female autointoxication over the period studied. The high percentage of autointoxication with psychotropic medications may be related to the ease of access at home and society's medicalization.
