Técnica "Mother and child" com um novo cateter: experiência inicial / "Mother and Child" technique with a new catheter: initial experience

Relatamos nossa experiência inicial com o GuideLinerTM, uma extensão de cateter-guia de rápida troca tipo “child”, desenvolvido para facilitar a entrega de stents e balões em intervençõesarteriais percutâneas complexas. Descrevemos sua utilização em um caso com lesão coronária complexa, em outro com anatomia complexa, e em um terceiro caso com dissecção do enxerto de artéria torácica interna esquerda. Todos os procedimentos foram realizados com sucesso. O GuideLinerTMpode auxiliar no tratamento de lesões arteriais complexas e de complicações durante o procedimento.

Association between mental health screening by self-report questionnaire and insomnia in medical students

Epidemiological research points to the high prevalence of psychiatric disorders among insomniacs. We carried out a cross-sectional study with medical students with the aim of evaluating the association between insomnia and suspicion of psychiatric disorder; 302 medical students were included (184 males and 118 females; mean age = 20.47Ý1.89 years). The main association was tested by logistic regression analysis. The overall prevalence of positivity in a screening test for psychiatric disorder was 22.19 percent; and of insomnia, 28.15 percent. Difficulty initiating sleep (OR=3.45), difficulty maintaining sleep (OR=7.61), falling asleep later (OR=1.99) and waking up earlier (OR=1.91) were associated with suspicion of psychiatric disorder. As a group, the variables difficulty initiating sleep, difficulty maintaining sleep, falling asleep after 11 pm, and waking up before 6 am presented an odds ratio of 5.96 for positivity in the screening for psychiatric disorder. Furthermore, difficulty maintaining sleep (OR=2.24) was associated with "being female," and falling asleep later (OR=0.43) was associated with "being male". These results underscore the importance of determining in what cases difficulty sleeping may have severe clinical repercussions or affect performance
