Desempenho Acadêmico De Alunos Que Se Submeteram A Tratamento Psiquiátrico No Serviço De Saúde Mental Para Estudantes De Uma Universidade Brasileira

University students are generally at the typical age of onset of mental disorders that may affect their academic performance. We aimed to characterize the university students attended by psychiatrists at the students’ mental health service (SAPPE) and to compare their academic performance with that of non-patient students. DESIGN AND SETTING: Cross-sectional study based on review of medical files and survey of academic data at a Brazilian public university. METHODS: Files of 1,237 students attended by psychiatrists at SAPPE from 2004 to 2011 were reviewed. Their academic performance coefficient (APC) and status as of July 2015 were compared to those of a control group of 2,579 non-patient students matched by gender, course and year of enrolment. RESULTS: 37% of the patients had had psychiatric treatment and 4.5% had made suicide attempts before being attended at SAPPE. Depression (39.1%) and anxiety disorders/phobias (33.2%) were the most frequent diagnoses. Severe mental disorders such as psychotic disorders (3.7%) and bipolar disorder (1.9%) were less frequent. Compared with non-patients, the mean APC among the undergraduate patients was slightly lower (0.63; standard deviation, SD: 0.26; versus 0.64; SD: 0.28; P = 0.025), but their course completion rates were higher and course abandonment rates were lower. Regarding postgraduate students, patients and non-patients had similar completion rates, but patients had greater incidence of discharge for poor performance and lower dropout rates. CONCLUSION: Despite the inclusion of socially vulnerable people with severe mental disorders, the group of patients had similar academic performance, and in some aspects better, than, that of non-patients. © 2017, Associacao Paulista de Medicina.

Effects of Anomalous Magnetic Moment in the Quantum Motion of Neutral Particle in Magnetic and Electric Fields Produced by a Linear Source in a Conical Spacetime

In this paper we analyse the effect of the anomalous magnetic moment on the non-relativistic quantum motion of a neutral particle in magnetic and electric fields produced by linear sources of constant current and charge density, respectively.Comment: 17 pages, no figur

On Aharonov-Casher bound states

In this work bound states for the Aharonov-Casher problem are considered. According to Hagen's work on the exact equivalence between spin-1/2 Aharonov-Bohm and Aharonov-Casher effects, is known that the $\boldsymbol{\nabla}\cdot\mathbf{E}$ term cannot be neglected in the Hamiltonian if the spin of particle is considered. This term leads to the existence of a singular potential at the origin. By modeling the problem by boundary conditions at the origin which arises by the self-adjoint extension of the Hamiltonian, we derive for the first time an expression for the bound state energy of the Aharonov-Casher problem. As an application, we consider the Aharonov-Casher plus a two-dimensional harmonic oscillator. We derive the expression for the harmonic oscillator energies and compare it with the expression obtained in the case without singularity. At the end, an approach for determination of the self-adjoint extension parameter is given. In our approach, the parameter is obtained essentially in terms of physics of the problem.Comment: 11 pages, matches published versio
