Listening to music, or part of it, may stir the memory of a past moment, along with its associated emotions, such occurrences are known as autobiographical memories. Electroencephalographic (EEG) studies have shown alterations in memory recall and musical processing. However, no research was found showing a relation among music, autobiographical memories and associated emotions. The purpose of this study was to identify cortical areas involved in the evocation of autobiographical memory (associated with positive and negative events) mediated by musical stimuli. For that, gamma rhythm was analyzed through EEG recordings performed by 45 male volunteers while they were submitted to two stimuli: 1) the music capable of recalling memories associated to a positive event; 2) the music capable of evoking memories associated to a negative event. Gamma band analysis was used in search of greater brain electrical activity. As results, researchers observed increased activity in right brain hemisphere during the musical processing, besides its hypoactivation when volunteers were submitted to musical stimuli related to memories of negative events.

Background There is little information available on stroke epidemiology in the northeast of Brazil. Objective Our objective was to investigate the prevalence of the stroke subtypes, prevalence of cerebrovascular risk factors and patterns of management in a public neurovascular outpatient referral service, in Alagoas. Methods Data were prospectively collected from consecutive patients with stroke who were treated in a specialized neurovascular clinic between November 2016 and June 2018. Recurrence was evaluated by telephone 12 months after patients had been included in the study. Results We evaluated 190 patients (mean age, 60.22 ( 13.29 years; 60.5% males). Ischemic stroke was the most frequent subtype (85.2%). Sedentary lifestyle was the most common risk factor (71.6%), followed by hypertension (62.6%) and stroke family history (41.1%). Only 21.5% of the patients were transported by ambulance to the hospital, and 42.6% received medical support in hospital units or emergency units with no imaging support. The median NIHSS was 2.5 (IQR, 1-5) and mRS was 2 (IQR, 1-3). We found a high rate of undetermined stroke (35.8%), and few patients completed the etiological investigation. One year after inclusion in the study, 12 patients (6.3%) had died and 14 (7.3%) had had another stroke. Conclusions The prevalence of cerebrovascular risk factors and clinical presentation were similar to what had been seen in previous series. A notable number of patients received medical support in institutions with no imaging equipment. The high number of cases of undetermined stroke etiology shows the difficulty in accessing healthcare services in Alagoas.

Objetivo: Analisar as características e incidência do trauma vesical durante cinco anos em um hospital geral do estado de Alagoas. Métodos: Estudo quantitativo, analítico, observacional e transversal, foram utilizados métodos de estatística descritiva para análise das variáveis. Resultados: Foram encontradas lesões vesicais em 63 pacientes, obteve-se análise dos prontuários nos anos de 2010 a 2015. Média de idade de 26,2 anos, com extremos entre 15 e 56 e desvio padrão de 9,85 (intervalo de confiança de 95%).  A maioria era (76,2%) do sexo masculino. O trauma penetrante foi responsável por 65,07% dos casos, sendo em sua maioria (97,56%) decorrente de lesão por arma de fogo. O método diagnóstico foi predominantemente intraoperatório (82,53%). As lesões mais frequentes foram de cúpula vesical (23,8%), parede anterior e posterior (11,11%).  O tratamento de escolha foi cirúrgico em 88,89% e conservador nos demais. A taxa de mortalidade global no trauma vesical foi de 7,93% a sobrevida média de 88,87%. Conclusão: Os dados encontrados são, em sua grande parte, condizentes com a literatura mundial para o trauma vesical, diferindo quanto a etiologia, método diagnóstico e a terapêutica adotada. Tais distinções, podem ser justificadas pelas características locais e do hospital estudado.
