Sabe-se que o acervo de músicas brasileiras é vasto e reflete as tradições do País em função da sua forte conexão com a cultura local. Do ponto de vista informacional e tecnológico, é importante caracterizar a música brasileira e os seus limites, a fim de permitir a construção estratégias de preservação e organização desses conteúdos musicais. Por outro lado, a literatura aponta algumas definições para o conceito de música brasileira que sugerem uma revisão a fim de formalizar as características desse repertório. Neste artigo é apresentado um estudo etnográfico com músicos especialistas no tema a fim de identificar uma definição mais precisa sobre música popular brasileira e seus atributos mais relevantes.

Apesar dos bons resultados gerados pelos estudos de necessidades e usos de informação musical publicados nos últimos anos, muitos deles se ressentem da falta de um referencial para apoiar a organização de conceitos e o mapeamento de variáveis associadas aos fenômenos, que se pretende investigar nesta área. Este artigo apresenta uma proposta de modelo comportamental para necessidades e usos de informação musical, a fim de facilitar a identificação de variáveis de análise e produção de instrumentos de coleta de dados, em estudos quantitativos e qualitativos. Para validação do modelo conceitual proposto, são apresentados resultados da sua aplicação em um estudo quantitativo exploratório, com usuários não especializados em música.Palavras-Chave: Estudos de usuários; Necessidades de informação musical.

ObjectiveTo describe the features related to patients with Covid-19 admitted to Unimed Recife hospitals, Recife, Brazil, evaluating demographic data, lethality, use of a mechanical ventilator, presence of associated diseases, the need to use the ICU, among other aspects related to the prognosis of these patients.MethodData were collected from the DRG Brazil health management platform, including the period from March 16, 2020, when the first patient with Covid-19 was admitted to the Hospital da Unimed III, until January 31, 2021. All patients admitted to one of the three hospitals of Unimed Recife - Hospital Unimed Recife I, Hospital Unimed Recife III, and Hospital Geral Unimed Recife – were included in the study. In the same period, we evaluated the number of patients with Covid-19 or suspected Covid-19 who were seen in the emergency room at Hospital Unimed Recife III.ResultsOne hundred twenty-six thousand five hundred fifty-three patients were seen in the Emergency Unit of Hospital Unimed Recife III in the period between March 26, 2020, and January 31, 2021; of those 126,553 patients seen in the emergency 39,340 (31.09%) patients were diagnosed with having Covid-19 or suspected of Covid-19. In the 10-month period, 1,039 patients with Covid-19 were hospitalized, 61% with hypertension, 31.1% with SARS, 30.0% with diabetes, and 9.9% were obese. The average hospital stay was 11.2 days. 342/1,039 (32.9%) patients were admitted to the ICU, and 57.9% of them had mechanical ventilation. The overall lethality was 13.76% (143 deaths/1,039 inpatients). An increase in lethality by Covid-19 was associated with increased age. Lethality in the first period of the Covid-19 pandemic was significantly higher when compared to the last 5 months of the pandemic(17.6% versus 9.7%). Obesity significantly increased lethality in patients with Covid-19 [120 deaths/1,016 non-obese patients (11.8%) versus 23 deaths/103 obese patients (22.3%), OR 2.15 (1.30 - 3.50), p = 0.005)].ConclusionWe conclude that Covid-19 is a disease with a poor prognosis, especially in the elderly and obese patients. In the second 5-month period of the Covid-19 pandemic, we noticed a significant reduction in lethality by Covid-19 in hospitalized patients. Covid-19 is a new disease and the mechanism by which the viruses multiply or how the pathophysiological process occurs in the infected organism are still barely understood.
