BACKGROUND People have been using psychoactive substances for a long time. Over the last few years, this practice has spread among university students, who use these substances to improve their academic performance, relieve stress and increase concentration and memory. OBJECTIVES To estimate the use of psychoactive drugs among healthcare students at a higher education institution in the city of Passo Fundo (RS), Brazil, and to ascertain the associated demographic and lifestyle factors. DESIGN AND SETTING Cross-sectional study in a higher education institution. METHODS We included 287 undergraduate medicine and dentistry students in this study. They answered a self-administered questionnaire regarding sociodemographic, lifestyle and health variables. The statistical analysis used univariate and bivariate analyses with Pearson's chi-square test (P-value less then 0.05). -Multivariate analyses were used to estimate odds ratios (OR) and their respective 95% confidence intervals. The SPSS software, version 20.0, was used. RESULTS The prevalence of use of psychoactive substances among the students was 24.7%. Among these students, high frequencies of psychoactive drugs had been prescribed by physicians (95.8%) and for the purpose of relaxation or stress relief (73.2%). Women, medical students (compared with dental students) and participants with lower academic performance were more likely to use psychoactive drugs. After the multivariate adjustment, the "course" and "academic performance" remained associated with use of psychoactive drugs. CONCLUSION There was high prevalence of psychoactive drug use among the students at the higher education institution investigated. Some variables (female sex, medical students and low academic performance) were associated with the outcome.BACKGROUND Studies have shown that physical activity levels can be inversely associated with high-sensitivity C-reactive protein (hs-CRP) levels. However, the amount of physical activity required to maintain normal hs-CRP levels is still a matter for speculation. OBJECTIVE To identify the amount of physical activity necessary to discriminate the hs-CRP levels in adults. DESIGN AND SETTING Cross-sectional study at six teaching and research institutions. METHODS The study sample comprised 10,231 adults aged 35 to 74 years who were participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Receiver operating characteristic (ROC) curves were constructed to compare the amount of physical activity in two domains (leisure time and commuting) with hs-CRP levels. The sensitivity and specificity were calculated to identify the best cutoff for physical activity level that would be needed to maintain normal levels of hs-CRP ( less then 3 mg/l). RESULTS The area under the ROC curve was only statistically significant for discriminating normal levels of hs-CRP according to the amount of physical activity when the two study domains were added together. The accumulated physical activity level of 200 minutes/week was the best cutoff for discriminating normal levels of hs-CRP in adults of both sex. CONCLUSIONS Physical activity in the leisure-time and commuting domains together, of duration 200 minutes/week, was associated with normal hs-CRP values.BACKGROUND Self-Estimated Functional Inability because of Pain (SEFIP) is a questionnaire specifically designed to measure musculoskeletal pain or discomfort. OBJECTIVE To perform translation and cross-cultural adaptation of the SEFIP for dancers (SEFIP-dance), for use in Brazilian Portuguese. In addition, as a secondary objective, we adapted the translated version of SEFIP-dance for use among athletes or exercise practitioners (SEFIP-sport). DESIGN AND SETTING Questionnaire translation and cross-cultural adaptation study conducted at a public university. METHODS The Brazilian version of the SEFIP-dance questionnaire was developed following the processes of translation (involving two translators with Brazilian Portuguese as their mother tongue and fluency in English), backtranslation (involving two translators with English as their mother tongue and fluency in Brazilian Portuguese), committee review and pre-testing. SEFIP-sport was developed following the processes of content and face validation. RESULTS SEFIP-dance was applied to 30 dancers, of mean age 22.38 years (standard deviation [SD] = 3.41), among whom 14 were men (46.66%). The participants understood 100% of the SEFIP-dance items and alternatives. SEFIP-sport was applied to 30 athletes or physical exercise practitioners, of mean age 25.09 years (SD = 8.93), among whom 25 were men (86.33%). The participants understood 100% of the -SEFIP-sport items and alternatives. CONCLUSION The Brazilian Portuguese versions of SEFIP-dance, translated and cross-culturally adapted for dancers, and SEFIP-sport, adapted for athletes or physical exercise practitioners, were shown to have adequate levels of understanding.INTRODUCTION This study investigated the prevalence of blood donors' test-seeking behavior and related factors among health sciences undergraduate students. METHODS A total of 750 students were invited. Data regarding sociodemographic and behavioral characteristics, blood donation practices, and test-seeking behavior were collected. RESULTS Of the invited students, 341 (45.5%) agreed to participate and answered questions regarding test-seeking behavior. The sample comprised 83.1% females, 96.8% singles, 87.2% heterosexuals, and 32.6% of them had previously donated blood. A high prevalence of blood donor test-seeking behavior (14.4%; 95% CI 10.8%-18.5%) was observed and associated with blood donation practices. CONCLUSIONS Test-seeking behavior was common among the interviewed students, thereby highlighting the importance of developing a better understanding of its determinants to prevent this behavior in key populations.We present the first recent reported case of traumatic injury caused by catfish in the Americas. Although 66.2% of fish-related injuries occur in the Amazon Region, they are scarcely reported. We report a traumatic injury in a 2-year-old boy who entered Madeira River. The use of traditional methods to treat the injury and his incomplete vaccination history reflect the weakness of the health system. Further, the fact that it was the second time that such an incident had occurred in the locality in 3 weeks during the dry season suggests that this could be a frequent occurrence during this period.INTRODUCTION Herein, we aimed to identify the factors associated with adverse drug events (ADEs) in chronic Chagas disease (CD) patients. METHODS We analyzed 320 medical notes from 295 patients. The Naranjo algorithm was applied to determine the cause of ADEs. Mixed effects logistic regression was performed to evaluate the factors associated with ADEs. RESULTS ADEs were described in 102 medical notes (31.9%). Captopril was most frequently associated with ADEs. Age (RR 0.96; 95%CI 0.94-0.99) and cardiac C/D stages (RR 3.24; 95%CI 1.30-4.58) were the most important clinical factors associated with ADEs. CONCLUSIONS Close follow-up is warranted for CD patients.INTRODUCTION DENV-2 is the cause of most dengue epidemics worldwide and is associated with severe cases. METHODS We investigated arboviruses in 164 serum samples collected from patients presenting with clinical symptoms of dengue fever and 152 mosquito pools. RESULTS We detected the Asian II genotype of DENV-2 in humans and mosquitoes. Our results confirmed the circulation of the Asian II genotype in Brazil, in addition to the prevalent Asian/American genotype. Selleckchem ML264 CONCLUSIONS The detection of Asian II genotype of DENV-2 in mosquito pools collected in a forest park may be related to a spillback event of human dengue virus.This is a case report about the only confirmed death in the State of Espírito Santo due to acute Chagas-related myocarditis in a 2-year-old child living in the rural area of Guarapari. He presented with fever, abdominal pain, headache, and vomiting, resulting in death 21 days after the presentation of symptoms. Amastigote forms were observed in the myocardial fibers in histological examination. The boy's mother had reported finding "kissing bugs" in the child's hand. This case highlights the need to include Chagas disease in the differential diagnosis in health care to provide early treatment and avoid death in affected individuals.INTRODUCTION Post-traumatic stress disorder (PTSD) is one of the most common psychiatric disorders found among victims of disaster, kidnapping, accidents, sexual assaults and war in Indonesia. However, lacking and unequal distribution of psychiatric medical personnel remains a barrier to its management. This review aims to introduce and evaluate the potential contribution of telepsychiatry to the management of PTSD based on published literature. METHODS Original studies were obtained from PubMed, Science Direct, ProQuest, High Wire, and Elsevier Clinical Key databases. RESULTS A total of 125 articles were found, of which 15 articles (12 randomized controlled trials, 2 open trials and 1 pilot study) fulfilled the inclusion criteria. A total of 991 subjects were found with a follow-up period ranging between 5 weeks and 18 months. Telepsychiatry is an innovative use of technology to aid the delivery of PTSD treatments in areas difficult to reach. The quality of care given by telepsychiatry both through video conferencing as well as web- and application-based is comparable to that of face-to-face therapy. Patient satisfaction, quality of doctor-patient relationship also remains high, with lower costs and shorter therapeutic time when compared to face-to-face therapy. CONCLUSION Various studies have shown that telepsychiatry is an effective solution for the management of PTSD. Studies have also reported that the quality of treatment through telepsychiatry is as effective as face-to-face therapy, with greater efficiency. Countries, especially those with a low patient-to-mental health professional ratio, should be encouraged to develop telepsychiatry systems to manage PTSD.OBJECTIVE Construct validity for the Motor Development Scale (MDS) has not been established. The aim of this study was to examine whether the unidimensional model of MDS would be appropriate for children aged 4 to 6 years-old and provide construct validity for the items concerning this age group in Brazil. METHODS A total of 938 children participated in the study (214 4-year-olds, 643 5-year-olds, and 81 6-year-olds). Confirmatory factor analysis (CFA) was used to evaluate construct validity of the MDS using a unidimensional model. RESULTS The CFA for the unidimensional model showed excellent adequacy indices for age 4 χ2(2) = 0.581, p = 0.748, comparative fit index (CFI) = 1.000, Tucker-Lewis index (TLI) = 1.090, root mean square error of approximation (RMSEA) = 0.000 (90% confidence interval [90%CI] = 0.000 to 0.093, close fit [Cfit] = 0.841); age 5 χ2(2) = 2.669, p = 0.263, CFI = 0.993, TLI = 0.980, RMSEA = 0.023 (90%CI = 0.000 to 0.085, Cfit = 0.682), weighted root mean square residual (WRMR) = 0.407; and age 6 χ2(9) = 8.275, p = 0.506, CFI = 1.000, TLI = 1.010, RMSEA = 0.000 (90%CI = 0.000 to 0.118, Cfit = 0.653), WRMR = 0.495. Reliability was good ω = 0.87 (95%CI = 0.81 to 0.92). CONCLUSION The proposed unidimensional solution for the MDS provides a concise, parsimonious and reliable way to assess motor development in children aged 4 to 6 years.
