Abstract Substance use disorder is one of the major social and public health problems in the world. The present study analyzed the pharmacoepidemiological profile of patients treated at the Psychosocial Treatment Center for Alcohol and Substance Use Disorders (CAPS-AD) for treatment of alcohol use disorders (AUD), cocaine use disorders (CUD) and concomitant alcohol and cocaine use disorders (A-CUD) in the city of Betim-MG. The study used quantitative and descriptive data and was based on the evaluation of medical records of patients attended from January to December 2016. After analyzing 295 medical records, the majority of study participants were male (83.7 %) with an average age of 46.26 for AUD, 28.88 for CUD and 34.29 for A-CUD. The most prescribed drugs for AUD were diazepam (54.1 %), thiamine (37 %), complex B vitamins (29.5 %), and disulfiram (2.7 %); for CUD, diazepam (26.9 %) and haloperidol (23.1 %). It should be noticed that although contraindicated by the guidelines, chlorpromazine (42.3 %, 25.3 %, 20.3 %) was prescribed for CUD, AUD, and A-CUD respectively. Knowing the pharmacoepidemiological profile of CAPS-AD patients is extremely important for making decisions regarding which medicines to make available to the population.

RESUMO Objetivo Adaptar um software de ajuste de dose de antibióticos inicialmente elaborado em língua inglesa para o português e a conjuntura brasileira. Métodos Trata-se de estudo observacional, descritivo, em que foi utilizado o método Delphi para estabelecer consenso entre especialistas de diferentes áreas da saúde, com perguntas que abordaram os aspectos visuais e operacionais do software. Em uma segunda etapa, foi realizado um estudo piloto, experimental, com alocação aleatória dos pacientes, para avaliação e adaptação do software em ambiente real de uma unidade de tratamento intensivo, onde foram comparadas diferenças entre pacientes que utilizaram dose padronizada usual de piperacilina/tazobactam, e os que utilizaram a dose individualizada ajustada por meio do software Individually Designed Optimum Dosing Strategies. Resultados Participaram da primeira rodada 12 profissionais cujas sugestões foram encaminhadas ao desenvolvedor do software para adequação e ajustes, e posteriormente submetidas à segunda rodada. Oito especialistas participaram da segunda rodada. Foram obtidos índices de 80% e 90% de concordância entre os juízes, caracterizando uniformidade nas sugestões. Dessa forma, houve modificação no layout do software para adequação linguística e cultural, minimizando erros de entendimento e contradições. Na segunda etapa, foram incluídos 21 pacientes, e não houve diferenças entre doses de piperacilina nos grupos dose padronizada e dose ajustada. Conclusão A versão adaptada do software é segura e confiável para seu uso no Brasil.

ABSTRACT Objective To adapt an antibiotic dose adjustment software initially developed in English, to Portuguese and to the Brazilian context. Methods This was an observational, descriptive study in which the Delphi method was used to establish consensus among specialists from different health areas, with questions addressing the visual and operational aspects of the software. In a second stage, a pilot experimental study was performed with the random comparison of patients for evaluation and adaptation of the software in the real environment of an intensive care unit, where it was compared between patients who used the standardized dose of piperacillin/tazobactam, and those who used an individualized dose adjusted through the software Individually Designed and Optimized Dosing Strategies. Results Twelve professionals participated in the first round, whose suggestions were forwarded to the software developer for adjustments, and subsequently submitted to the second round. Eight specialists participated in the second round. Indexes of 80% and 90% of concordance were obtained between the judges, characterizing uniformity in the suggestions. Thus, there was modification in the layout of the software for linguistic and cultural adequacy, minimizing errors of understanding and contradictions. In the second stage, 21 patients were included, and there were no differences between doses of piperacillin in the standard dose and adjusted dose Groups. Conclusion The adapted version of the software is safe and reliable for its use in Brazil.

RESUMO Objetivo Analisar a efetividade microbiológica considerando a correlação farmacocinética/farmacodinâmica de vancomicina em crianças e propor uma estimativa de ajuste na dose. Métodos Trata-se de um estudo observacional, transversal, realizado em hospital pediátrico, no período de 1 ano (2016 a 2017). Foram incluídas crianças de 2 a 12 anos de ambos os sexos, tendo sido excluídas crianças queimadas ou submetidas à terapia renal substitutiva. Para análise farmacocinética, foram coletadas duas amostras de 2mL de sangue total, respeitando o intervalo de 2 horas entre cada coleta. Resultados Foram incluídos dez pacientes pediátricos com idade de 5,5 anos (mediana) e intervalo interquartil (IQ) de 3,2-9,0 anos, peso de 21kg (mediana; IQ: 15,5-24,0kg) e altura de 112,5cm (mediana; IQ: 95-133cm). Apenas uma criança alcançou concentrações mínimas entre 10µg/mL e 15µg/mL. Conclusão A utilização empírica de vancomicina na população de crianças não alcançou o alvo farmacocinético/farmacodinâmico terapêutico para concentração inibitória mínima de 1μg/mL.

ABSTRACT Objective Analyze the microbiological effectiveness, based on the pharmacokinetics/pharmacodynamics correlation of vancomycin in pediatric patients, and to propose dose adjustment. Methods This is an observational, cross-sectional study, conducted in a pediatric hospital, over a 1-year period (2016 to 2017). Children of both sexes, aged 2 to 12 years, were included in the study; burn children, and children in renal replacement therapy were excluded. For the pharmacokinetic analysis, two samples of 2mL of whole blood were collected, respecting the 2-hour interval between each withdrawal. Results Ten pediatric patients with median age of 5.5 years and interquartile range (IQR) of 3.2-9.0 years, median weight of 21kg (IQR: 15.5-24.0kg) and median height of 112.5cm (IQR: 95-133cm), were included. Only one child achieved trough concentrations between 10µg/mL and 15µg/mL. Conclusion The empirical use of vancomycin in the children studied did not achieve the therapeutic pharmacokinetic/pharmacodynamic target for minimum inhibitory concentration of 1µg/mL.

ABSTRACT Cancer is a multifactorial disease and a serious public health problem. Currently, alternative drug treatments for cancer are actively being sought, which is the case of synthetic phosphoethanolamine (PHOS-S), a compound that could possibly have anticarcinogenic effects. To analyze the available scientific evidence to evaluate the anticarcinogenic effects of in vivo and in vitro PHOS-S. A systematic literature review of scientific articles aimed at evaluating the anticarcinogenic potential of PHOS-S, in vivo and in vitro, using the databases PubMed, ScienceDirect, SciElo, CAPES Portal and LILACS. The selected papers suggest a possible anticarcinogenic effect of PHOS-S by inhibiting tumor growth by inducing apoptosis and cell cycle blockade as well as cytotoxic potential against leukemia cells. However, a possible stimulatory effect of tumor growth was also observed. Although some of the evaluated studies indicated a possible anticarcinogenic effect of PHOS-S, the limitations of these studies must be evaluated. Most were performed by the same research group, and in the scientific literature, we identified only preclinical studies (in cells or in animals). No human study has been published. Thus, more studies are needed to confirm the anticarcinogenic capacity of PHOS-S.

Durante as últimas décadas, o mundo passou por uma transformação demográfica, com um rápido crescimento da população idosa e, portanto, tanto a demanda para a manutenção da saúde deste grupo populacional, quanto o consumo de medicamentos estão aumentando. Ainda, as mudanças farmacocinéticas e farmacodinâmicas que ocorrem em idosos podem interferir diretamente nos efeitos adversos dos medicamentos e aumentar o risco de intoxicação. Além disso, há fatores externos que interferem na farmacoterapia dos idosos, tais como o uso inadequado e a falta de acesso à informação. Existem várias classes terapêuticas de medicamentos que devem ser utilizados com cautela ou evitados na população idosa, tais como antiinflamatórios, alguns anti-hipertensivos, diuréticos, digitálicos entre outros. Estes medicamentos, se não forem utilizados com cuidado, podem afetar a qualidade de vida e a segurança desta população. Assim, este trabalho visa identificar medicamentos que devem ser utilizados com cuidado em pacientes idosos para evitar intoxicações e/ou eventos adversos aos medicamentos.

In recent decades, the world has undergone a demographic transformation with a rapid growth of the elderly population, resulting in an increased demand for funds to maintain their health and drug consumption. Pharmacokinetic and pharmacodynamic changes occurring in the elderly can interfere directly in the adverse effects of drugs and increase the risk of intoxication. In addition, there are external factors interfering with the pharmacotherapy of the elderly, such as inappropriate use and the lack of access to information. Many therapeutic classes of drugs should be used with caution or avoided in the elderly population, such as anti-inflammatory and some anti-hypertensive drugs, diuretics and digitalis. If not managed carefully, these medicines can affect the safety and quality of life in the elderly. Thus, the aim of this review was to identify drugs that should be used with caution in elderly patients in order to avoid intoxication and/or adverse drug events.

The common everyday use of medicinal plants is an ancient, and still very widespread practice, whereby the need for studies on their possible toxicity and mutagenic properties. The species Coccoloba mollis has been much used in phytotherapy, mainly in cases involving loss of memory and stress. In order to investigate its genotoxic and mutagenic potential, ethanolic extracts from the leaves and roots underwent Salmonella/microsome assaying (TA98 and TA100 strains, with and without exogenous metabolism - S9), besides comet and micronucleus tests in vivo.There was no significant increase in the number of revertants/plate of Salmonella strains in any of the analyzed root-extract concentrations, although the extract itself was extremely toxic to the Salmonella TA98 strain in the tests carried out with S9 (doses varying from 0.005 to 0.5 µg/plate). On the other hand, the leaf-extract induced mutations in the TA98 strain in the absence of S9 in the highest concentration evaluated, although at very low mutagenic potency (0.004 rev/µg). Furthermore, there was no statistically significant increase in the number of comets and micronuclei, in treatments involving Swiss mice. It was obvious that extracts of Coccoloba mollis, under the described experimental conditions, are not mutagenic.
