Síndrome de Burnout em graduandos de Odontologia Burnout syndrome among dental students

A Síndrome de Burnout caracteriza-se por esgotamento profissional e tem sido relatada em estudantes universitários. O objetivo desse estudo foi estimar a prevalência da Síndrome de Burnout em estudantes de Odontologia de uma universidade pública e sua relação com características sociodemográficas. Todos os estudantes (n = 300) foram convidados a participar. Utilizou-se o Inventário de Burnout de Maslach - versão estudantes (MBI-SS). Realizou-se análise das propriedades psicométricas do MBI-SS. Para comparação entre os escores médios das dimensões do Burnout realizou-se Análise de Variância Multivariada (MANOVA) seguida de Análise de Variância (ANOVA) e testes post-hoc de Tukey. Dos 235 participantes, 72,8% eram mulheres e a média de idade era de 21,0 ± 1,8 anos. O MBI-SS mostrou-se confiável e válido. Dos estudantes, 17,0% apresentaram a Síndrome de Burnout. Verificou-se relação significativa entre a Síndrome de Burnout e o desempenho do estudante no curso (F = 4,433, p < 0,001), o consumo de medicação devido aos estudos (F = 7,721, p < 0,001) e o pensamento de desistir do curso (F = 16,168, p < 0,001). Foram mais acometidos aqueles com desempenho ruim no curso, que consomem medicações devido aos estudos e que já pensaram em desistir do curso. Conclui-se que a prevalência da Síndrome entre os estudantes de Odontologia foi alta, sendo significativa a relação entre a Síndrome e o desempenho do estudante no curso, o consumo de medicação devido aos estudos e o pensamento de desistir do curso.<br>The burnout syndrome is characterized by professional exhaustion and has been reported in college students. The aim of this study was to estimate the prevalence of Burnout Syndrome among dentistry students from a public university, and its relationship to socio-demographic characteristics. All students (n = 300) were invited to participate. We used the Maslach Burnout Inventory - Student Version (MBI-SS). We carried out an analysis of the MBI-SS' psychometric properties. Multivariate Analysis of Variance (MANOVA) was performed, followed by Analysis of Variance (ANOVA) and Tukey's post-hoc tests to compare the mean scores of burnout dimensions. Of the 235 participants, 72.8% were women and the mean age was 21.0 ± 1.8 years. The MBI-SS was reliable and valid. Of the students, 17.0% had Burnout Syndrome. There was a significant relation between Burnout Syndrome and a student's performance during the course (F = 4.433, p < 0.001), medication intake because of studies (F = 7.721, p < 0.001), and the thought of dropping the course (F = 16.168, p < 0.001). The students most affected were those with poor performance, those who took medication because of studies, and those with thoughts of dropping the course. We concluded that the prevalence of the syndrome among dentistry students was high, with a significant relation between the syndrome and a student's academic performance, use of medication because of studies, and thoughts of dropping the course

Measurement of jet fragmentation in Pb plus Pb and pp collisions at root s(NN)=2.76 TeV with the ATLAS detector at the LHC

The distributions of transverse momentum and longitudinal momentum fraction of charged particles in jets are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The distributions are measured as a function of jet transverse momentum and rapidity. The analysis utilises an integrated luminosity of 0.14 nb(-1) of Pb+Pb data and 4.0 pb(-1) of pp data collected in 2011 and 2013, respectively, at the same centre-of-mass energy of 2.76 TeV per colliding nucleon pair. The distributions measured in pp collisions are used as a reference for those measured in Pb+Pb collisions in order to evaluate the impact on the internal structure of jets from the jet energy loss of fast partons propagating through the hot, dense medium created in heavy-ion collisions. Modest but significant centrality-dependent modifications of fragmentation functions in Pb+Pb collisions with respect to those in pp collisions are seen. No significant dependence of modifications on jet p(T) and rapidity selections is observed except for the fragments with the highest transverse momenta for which some reduction of yields is observed for more forward jets
