ABSTRACT
Resumo: Estudo retrospectivo longitudinal ecologico com dados referentes ao uso de hemocomponentes entre janeiro de 2008 e dezembro de 2021 na rede hospitalar do municipio de Belo Horizonte, Minas Gerais. Objetivos: Descrever as series mensais do numero de transfusoes de hemocomponentes e a taxa de transfusao por internacao em internacoes gerais na rede publica hospitalar sob a perspectiva da analise de series temporais. Metodos: A partir de dados do Sistema de Informacao Hospitalar do SUS (SIH-SUS), foram criadas seis series temporais de periodicidade mensal do numero de transfusoes de hemocomponentes e da taxa de transfusao por internacao. A estacionariedade, a tendencia e a sazonalidade das series foram verificadas pelo teste de raiz unitaria, pelo teste de Mann-Kendall e pelo teste de Fisher, respectivamente, utilizando-se os niveis de significancia de 10% para o primeiro teste e de 5% para os dois ultimos. Resultados: A taxa media mensal de uso de hemocomponentes por internacao hospitalar observada foi de 45,5%, 26,9% e 26,3% no Hospital Risoleta Tolentino Neves (HRN), Hospital Dr. Celio de Castro (HCC) e Hospital Odilon Behrens (HOB), respectivamente. A maior reducao do numero de transfusoes de hemocomponentes foi observada no HCC e a maior reducao da taxa de uso de hemocomponentes foi observada no HRN. O concentrado de hemacias foi o hemocomponente mais utilizado no HRN, HOB e HCC (54,6%, 58,3% e 65,4%, respectivamente). Todas as series apresentaram-se nao estacionarias, com tendencia de queda e presenca do componente sazonal com periodicidade de 12 meses. Todas as series apresentaram reducao da tendencia de queda durante o periodo critico da pandemia da COVID-19. Discussao: Os resultados encontrados neste estudo confirmam a hipotese inicial deste estudo de que o principal hemocomponente transfundido nos servicos de saude hospitalares publicos do municipio de Belo Horizonte sao os concentrados de hemacias. As taxas de transfusoes de hemocomponentes observadas nos tres hospitais sao semelhantes as taxas observadas em estudos nacionais e internacionais. A tendencia de queda na taxa de transfusoes de hemocomponentes por internacao hospitalar vai de encontro ao observado na literatura, que aponta para o aumento das taxas de transfusoes de hemocomponentes e dos resultados de um estudo semelhante realizado com uma rede de hospitais privados do mesmo municipio, no qual foi identificada a tendencia de alta em todos os hospitais analisados no estudo. A inexistencia dos dados sociodemograficos e informacoes sobre o local de utilizacao dos hemocomponentes podem ser considerados limitacoes do estudo. Conclusao: O estudo permitiu compreender o comportamento das series temporais relacionadas ao uso de hemocomponentes na rede publica hospitalar do municipio de Belo Horizonte. Acoes que envolvem a reducao da demanda por hemocomponentes, como, por exemplo, a implementacao de programas de Patient Blood Management, podem ser realizadas nos tres hospitais, com primazia para o HRN e para os concentrados de hemacias nos tres hospitais.

ABSTRACT
OBJECTIVE: To identify symptoms of COVID-19 in adults in the scientific literature. METHOD: Systematic review of studies published from December 1, 2019 to April 21, 2020 from the Scopus, Web of Science and PubMed databases, in order to answer the following research question: "What are the symptoms caused by COVID-19 in adults?" using the keywords "Symptoms", "Clinical Manifestations", "Coronavirus", "COVID-19". RESULTS: Of the total 105 references, 13 references that addressed the symptoms of COVID-19 were selected. Fever and normal or dry cough were symptoms present in all studies. CONCLUSION: The symptoms identified in adult patients were fever, normal or dry cough, headache, pharyngalgia, dyspnea, diarrhea, myalgia, vomiting, sputum or expectoration, anxiety or chest pain, fatigue, nausea, anorexia, abdominal pain, rhinorrhea, runny nose or nasal congestion, dizziness, chills, systemic pain, mental confusion, hemoptysis, asthma, taste disorder, smell disorder, belching and tachycardia.
ABSTRACT
BACKGROUND: The pandemic of the new coronavirus has culminated in a scientific race to seek knowledge about this virus and its treatments, vaccines and preventive strategies, in order to reduce its impact on healthcare and economics worldwide. Hence, it is important to recognize the efforts of researchers who are at the forefront of investigations relating to the new coronavirus. OBJECTIVE: The present study was carried out with the aim of analyzing the world scientific production relating to COVID-19. DESIGN AND SETTING: Exploratory and descriptive bibliometric study conducted in the city of Teresina (PI), Brazil. METHOD: ISI Web of Knowledge/Web of Science (WOS) was chosen as the database. Data-gathering was carried out in May 2020. The data analysis was performed using the HistCiteTM software, version 9.8.24, and the VOSviewer bibliometric analysis software, version 1.6.8. RESULTS: 2,625 published papers that included descriptors within the scope of this investigation were identified. These articles were published in 859 different journals that are indexed in WOS, by 9,791 authors who were linked to 3,365 research institutions, located in 105 countries. CONCLUSION: Ascertaining scientific production through a bibliometric analysis is important in order to guide researchers on what has already been produced and what is being researched, so as to be able to address gaps in knowledge through future research.
