[Excerto] Escola, desde sempre, se apresentou como um espaço de liberdade e diversidade que fomenta a curiosidade e a produção de conhecimento, conferindo autonomia científica, técnica e profissional a todos os que nela se formam e diferenciam. Esta Escola representa, a todos os níveis, um marco inovador na formação médica, primando pela excelência, não só nos eixos de atividade tradicionais – pedagógico, cient...
Acute porphyrias are a group of rare genetic metabolic disorders, caused by a defect in one of the enzymes involved in the heme biosynthesis, which results in an abnormally high accumulation of toxic intermediates. Acute porphyrias are characterized by potentially life-threatening attacks and, for some patients, by chronic manifestations that negatively impact daily functioning and quality of life. Clinical man...
The solubility (Henry’s constant) of xenon in a series of n-alkanes (n-heptane, n-octane, n-nonane, ndodecane and n-hexadecane) and in two cycloalkanes (cyclopentane and cyclohexane) has been obtained by Monte Carlo computer simulations as a function of temperature, at a reference pressure of 100 kPa and compared with experimental results from literature. The n-alkanes and cycloalkanes were modelled with the un...
This work presents a systematic study of asphaltene pre-aggregation phenomena in the absence and in the presence of ionic liquids (ILs) from the family of 1-alkyl-3- methylimidazolium by molecular dynamics simulations. The effects of the alkyl chain length of the cation (studying ILs with alkyl chains between C4 and C10) and of the dimension of the anion (testing chloride and bromide) on the aggregation behavio...
The liquid density of five liquid 1H,1H-perfluorinated alcohols (CF3(CF2)n−1CH2OH n = 2, 3, 4, 5, 6) was measured as a function of pressure (0.1−70 MPa) and temperature (293.15−313.15 K). The corresponding isothermal compressibility and isobaric thermal expansivity coefficients were calculated from the experimental data. The results are compared with data from the literature for the equivalent hydrogenated alco...
Introdução: As consultas informais são atos médicos caracterizados pela autorreferenciação a um médico, sem registo clínico ou seguimento adequado. Apesar de controversa, esta prática assume-se como parte integrante da cultura médica. Este caso clínico mostra a importância de compreender as consequências das consultas informais e as vantagens de uma atitude preventiva em relação à saúde do próprio. Descrição do...
Medical students are a population that is vulnerable to the development of anxiety, depression, and burnout. This observational cross-sectional study sought to assess the levels of distress and identify precipitating factors in all students enrolled in a Portuguese medical school during the academic year of 2022/23. Students (n = 768) were surveyed via validated instruments to measure anxiety, depression, and b...
During the first COVID-19 related confinement in Portugal, there was a decrease in the levels of psychological symptoms measured by the Depression, Anxiety and Stress Scale 21 (March to April 2020). Upon experiencing a new period of restraints in 2021, the psychological impact of this sample was assessed again (<i>N</i> = 322, two more time points). It was expected that the psychological symptoms evidenced in F...
