Increase of binucleated cells in the oral mucosa: a study on the use of psychotropics by students of a Brazilian institution

Factors Associated With Use of Medications for Anxiety and Depression in Pharmacy Students in Brazil

Objective. To map undergraduate pharmacy students' use of medications for anxiety and depression and associated factors at one university in Brazil.Methods. A cross-sectional study was conducted from May to July 2019 among undergraduate pharmacy students at one university. Data regarding sociodemographic issues and the use of psychotropics were collected using an online questionnaire. Exploratory descriptive analysis of data, the chi-square test, and multivariate binary logistic regression were performed to identify factors associated with the use of medications for anxiety and depression.Results. Of 900 students enrolled, usable survey responses were received from 198. Most respondents were female with a mean age of 22.3 years. Among these, 17.7% of pharmacy students used medications to treat anxiety and 13.1% used medications for depression. The most common psychotropics were escitalopram and fluoxetine. There were two peak usage times: the initial and final year of pharmacy school. Dissatisfaction with the pharmacy program and psychological care were significantly associated with the use of medications for anxiety. In contrast, monthly income from three to 15 times the minimum wage, religiosity/spirituality, and psychological care were associated with students' use of medications for depression.Conclusion. There was a high prevalence of medication use to treat anxiety and depression among undergraduate pharmacy students, and this use was associated with psychological care, monthly income, and religiosity/spirituality.

Buccal micronucleus cytome assay: Inter-laboratory scoring exercise and micronucleus and nuclear abnormalities frequencies in different populations from Brazil

The Buccal Micronucleus Cytome Assay (BMCyt) has become an important biomonitoring tool for assessing cytogenetic damage in many studied populations. Each laboratory applies protocols that vary according to the method of collecting and preparing samples. Besides, Brazil is a country of great territorial extensions that received immigrants from various parts of the world with different genetic backgrounds. Therefore, the present study aimed to evaluate the inter-laboratory variation in scoring the same set of slides using the more comprehensive scoring criteria, to standardize the BMCyt protocol, to observe the basal alterations in populations of different Brazilian regions and to compare it with other places around the world. Our results showed that a valuable number of laboratories participated, ten laboratories from different regions of the country, for the validation of the BMCyt in human biomonitoring studies, resulting in the 804 healthy individuals. This was possible because we observed: a range of measures needs to be considered, such as the baseline frequency of DNA damage and cell death in non-exposed individuals; age when grouped showed an influence on DNA damage, although when evaluated by group we did not see an influence; association between smoking habit and all endpoints of the BMCyt (except karyolytic cells) was evident; the basal MN frequency, in the majority of groups, follows those around the world; and the BMCyt was confirmed as a good health status biomarker. We emphasize the need for constant discussions on the parameters of cell death due to greater difficulty among the analyzers.
