OBJECTIVE@#To explore clinical rules based on the big data of the emergency department of the Second Affiliated Hospital of Guangzhou Medical University, and to establish an integrated platform for clinical research in emergency, which was finally applied to clinical practice.@*METHODS@#Based on the hospital information system (HIS), laboratory information system (LIS), emergency specialty system, picture archiving and communication systems (PACS) and electronic medical record system of the Second Affiliated Hospital of Guangzhou Medical University, the structural and unstructured information of patients in the emergency department from March 2019 to April 2022 was extracted. By means of extraction and fusion, normalization and desensitization quality control, the database was established. In addition, data were extracted from the database for adult patients with pre screening triage level III and below who underwent emergency visits from March 2019 to April 2022, such as demographic characteristics, vital signs during pre screening triage, diagnosis and treatment characteristics, diagnosis and grading, time indicators, and outcome indicators, independent risk factors for poor prognosis in patients were analyzed.@*RESULTS@#(1) The data of 338 681 patients in the emergency department of the Second Affiliated Hospital of Guangzhou Medical University from March 2019 to April 2022 were extracted, including 15 modules, such as demographic information, triage information, visit information, green pass and rescue information, diagnosis information, medical record information, laboratory examination overview, laboratory information, examination information, microbiological information, medication information, treatment information, hospitalization information, chest pain management and stroke management. The database ensured data visualization and operability. (2) Total 140 868 patients with pre-examination and triage level III and below were recruited from the emergency department database. The gender, age, type of admission to the hospital, pulse, blood pressure, Glasgow coma scale (GCS) and other indicators of the patients were included. Taking emergency admission to operating room, emergency admission to intervention room, emergency admission to intensive care unit (ICU) or emergency death as poor prognosis, the poor prognosis prediction model for patients with pre-examination and triage level III and below was constructed. The receiver operator characteristic curve and forest map results showed that the model had good predictive efficiency and could be used in clinical practice to reduce the risk of insufficient emergency pre-examination and triage.@*CONCLUSIONS@#The establishment of high-quality clinical database based on big data in emergency department is conducive to mining the clinical value of big data, assisting clinical decision-making, and improving the quality of clinical diagnosis and treatment.

Impactos da insuficiência cardíaca no sistema de saúde e previdenciário brasileiro: qual é o custo da doença? / Impacts of heart failure on the Brazilian health and pension system: what is the cost of the disease?

Objetivo: Estimar os principais custos indiretos da insuficiência cardíaca (IC) na população brasileira, sobre o sistema de saúde, o custo previdenciário e o quanto se perde em produtividade pelas complicações da doença. Métodos: Estudo ecológico desenvolvido com dados secundários, para a série histórica de 2018 a 2021, minerados do Departamento de Informática do Sistema Único de Saúde (Datasus), do Instituto Brasileiro de Geografia e Estatística (IBGE), e indicadores previdenciários coletados da Previdência Social e Instituto Nacional do Seguro Social (INSS). Resultados: Foram registrados 77.290 óbitos por IC no Brasil para o período, distribuídos uniformemente em relação ao sexo. A taxa de mortalidade foi diversificada entre as regiões brasileiras, com ênfase para Sudeste e Nordeste. As projeções indicam um gasto total de mais de R$ 1 bilhão com hospitalizações, com custo médio hospitalar de R$ 1.725,27 por pessoa. O custo médio por internação ultrapassou os R$ 2 bilhões de reais. Aproximadamente 3% das despesas federais são destinadas a pagamentos de benefícios relacionados a IC. Do total de afastamentos, 65% correspondem a homens e 35%, a mulheres, com custos que podem chegar a R$ 6 bilhões perdidos por ano. Conclusão: Os resultados sugerem um aumento do afastamento de portadores de IC da força de trabalho, o que acarreta maiores dispêndios para o sistema de saúde e pagamentos de benefícios previdenciários, como auxílio-doença e aposentadoria por incapacidade de longa duração. Este é o primeiro estudo que estima e correlaciona os dados socioepidemiológicos e os custos de saúde e previdenciários da IC no Brasil.

Objective: To estimate the main indirect costs of heart failure (HF) in the Brazilian population, on the health system, social security cost, and how much is lost in productivity due to the complications of the disease. Methods: Ecological study developed with secondary data, for the historical series from 2018 to 2021, mined from the Department of Informatics of the Unified Health System (Datasus), from the Brazilian Institute of Geography and Statistics (IBGE), and social security indicators collected from Social Security and the National Social Security Institute (INSS). Results: There were 77,290 deaths from HF in Brazil for the period, evenly distributed according to sex. The mortality rate was diversified among Brazilian regions, with emphasis on the Southeast and Northeast. Projections indicate a total expenditure of more than BRL 1 billion with hospitalizations, with an average hospital cost of BRL 1,725.27 per person. The average cost per hospitalization exceeded BRL 2 billion. Approximately 3% of federal expenditures are earmarked for IC benefit payments. Of the total number of absences, 65% correspond to men and 35% to women, with costs that can reach R$ 6 billion lost per year. Conclusion: The results suggest an increase in the removal of HF patients from the workforce, which leads to higher expenditures for the health system and payments of social security benefits, such as sick pay and retirement due to long-term disability. This is the first study that estimates and correlates socio-epidemiological data, health and social security costs of HF in Brazil.

Plataformização e o uso da informação para a criação de estímulos de consumo / Platformization and the use of information for the creation of consumption response / La plataformización y el uso de la información para crear estímulos al consumidor

Resumo Vivemos numa sociedade em que a existência está diretamente associada a visibilidade dos indivíduos. As construções narrativas que validam este processo trabalham com imagens e vídeos que projetam e constroem as nossas vivências em múltiplas plataformas digitais. Através delas é possível mapear boa parte de nossas ações e interações. Esses dados são valiosos indicativos de nosso comportamento social e emocional diante de variados temas e situações. As plataformas digitais utilizam essas informações na dinâmica do capitalismo de dados, extraindo valor a partir de mecanismos automatizados de coleta e operados por sujeitos algorítmicos. Por meio da organização de Big Data novos padrões de consumo são estimulados através de entregas customizadas para determinados grupos de pessoas interconectadas. Este estudo mostra as características deste processo operado em ambientes heterotópicos em que o espaço-tempo é formatado pela lógica das plataformas. Além disso, será apresentado um panorama sobre como esse artifício se tornou possível por causa da necessidade de relevância em que a autonomia do indivíduo nas redes é proporcional a sua submissão as regras de vigilância e exploração econômica. Através desta premissa este estudo apresenta dados recentes sobre a relação de confiança dos brasileiros nestas plataformas digitais que, paradoxalmente, ocupam lugar de destaque como fonte de informação primordial para boa parte da população no Brasil.

Abstract We live in a society in which the existence is directly associated with the visibility of the individuals. The narrative constructions that validate these processes work with images and videos that project and build our experiences on multiple digital platforms. Through them it is possible to map part of our actions and interactions. These data are valuable indicators of our social and emotional behavior in the face of many themes and situations. Digital platforms use this information in the dynamic of data capitalism, extracting value from automated collection mechanisms operated by algorithmic subjects. Through the Big Data organization, consumption patterns are stimulated through customized deliveries for certain groups of interconnected people. This study shows the characteristics of this process operated in heterotopic environments in which space-time is operated by the platform logic. In addition to that, an overview will be presented on how this artifice became possible because of the need for relevance in which the individuals autonomy in networks is proportional to their submission to the rules of surveillance and economic exploitation. Through this premise, this study also presents recent data on the trust relationship of Brazilians in these digital platforms that, paradoxically, occupy a prominent place as a primary source of information for a large part of the population in Brazil.

Chinese expert consensus on big data and real world study in cancer research (2022 edition) / 中华肿瘤杂志

Cancer is a public health and social problem to which great attention should be attached. Not only are there a large number of cancer patients in China, but great differences also exist in etiology, epidemiology, disease spectrum, and treatment between China and western countries. Therefore, tumor-related data in China has its own characteristics. Full reference to the data of western countries cannot accurately reflect the real situation of cancer prevention and treatment in China. If we can integrate, process and analyze Chinese data, and find rules in specific etiology, incidence, drug sensitivity and prognosis, it will play an important role in the formulation of health policy, medical research and disease prevention. The Society of Cancer Big Data and Real World Study of China Anti-Cancer Association organized multidisciplinary experts, combined with domestic and foreign literature and clinical practice, after repeated discussion and revision, finished this consensus including background, analysis and management, direction planning and operation flow, basic design, quality control standards, evidence level classification, data security and privacy standards of big data and real world study. The aim is to take full advantages of Chinese cancer big data to carry out high-quality real world study, and better promote the prevention and treatment of cancer in China.

Research progress of micronucleus visualization analysis and artificial intelligence detection strategy / 中华预防医学杂志

The micronucleomics test can comprehensively display a variety of harmful endpoints, such as DNA damage and repair, chromosome breakage or loss and cell growth inhibition, with fast, simple and economical feature. Micronucleomics is not only widely used in the comprehensive assessment of the types and modes of genetic action of exogenous chemicals (such as drugs, food additives, cosmetics, environmental pollutants, etc.), but also plays an important role in the screening and risk assessment of cancer population at high risk. However, the traditional micronucleomics image counting method has the characteristics of time-consuming, low accuracy, and high cost, which cannot meet the current analysis requirements of large-scale, multi-index, rapidity, high precision and visualization. In recent years, with the rapid development of the era of precision medicine based on big data, visualized analysis of new micronucleomics based on machine learning and detection strategies based on deep learning have shown a good application prospect. This review, based on the application value of micronucleomics, systematically compares the traditional and new artificial intelligence counting of micronucleus images, and discusses the future direction of micronucleus image detection.

Correlation analysis of smell and taste loss with COVID-19 outbreak trend based on big data of internet / 中华耳鼻咽喉头颈外科杂志

Objective: To analyze the correlation between loss of smell/taste and the number of real confirmed cases of coronavirus disease 2019 (COVID-19) worldwide based on Google Trends data, and to explore the guiding role of smell/taste loss for the COVID-19 prevention and control. Methods: "Loss of smell" and "loss of taste" related keywords were searched in the Google Trends platform, the data were obtained from Jan. 1 2019 to Jul. 11 2021. The daily and newly confirmed COVID-19 case number were collected from World Health Organization (WHO) since Dec. 30 2019. All data were statistically analyzed by SPSS 23.0 software. The correlation was finally tested by Spearman correlation analysis. Results: A total of data from 80 weeks were collected. The retrospective analysis was performed on the new trend of COVID-19 confirmed cases in a total of 186 292 441 cases worldwide. Since the epidemic of COVID-19 was recorded on the WHO website, the relative searches related to loss of smell/taste in the Google Trends platform had been increasing globally. The global relative search volumes of "loss of smell" and "loss of taste" on Google Trends was 10.23±2.58 and 16.33±2.47 before the record of epidemic while 80.25±39.81 and 80.45±40.04 after (t value was 8.67, 14.43, respectively, both P<0.001). In the United States and India, the relative searches for "loss of smell" and "loss of taste" after the record of epidemic were also much higher than before (all P<0.001). The correlation coefficients between the trend of weekly new COVID-19 cases and the Google Trends of "loss of smell" in the global, United States, and India was 0.53, 0.76, and 0.82 respectively (all P<0.001), the correlation coefficients with Google Trends of "loss of taste" was 0.54, 0.78, and 0.82 respectively (all P<0.001). The lowest and highest point of loss of smell/taste search curves of Google Trends in different periods appeared 7 to 14 days earlier than that of the weekly newly COVID-19 confirmed cases curves, respectively. Conclusions: There is a significant positive correlation between the number of newly confirmed cases of COVID-19 worldwide and the amount of keywords, such as "loss of smell" and "loss of taste", retrieved in Google Trends. The trend of big data based on Google Trends might predict the outbreak trend of COVID-19 in advance.

Epidemiological analysis of lower limb revascularization for peripheral arterial disease over 12 years on the public healthcare system in Brazil / Análise epidemiológica da revascularização de membros inferiores para doença arterial periférica em 12 anos no sistema público de saúde do Brasil

Abstract Background Worldwide, peripheral arterial disease (PAD) is a disorder with high morbidity, affecting more than 200 million people. Objectives Our objective was to analyze surgical treatment for PAD provided on the Brazilian Public Healthcare System over 12 years using publicly available data. Methods The study was conducted with analysis of data available on the Brazilian Health Ministry's database platform, assessing distributions of procedures and techniques over the years and their associated mortality and costs. Results A total of 129,424 procedures were analyzed (performed either for claudication or critical ischemia, proportion unknown). The vast majority of procedures were endovascular (65.49%) and this disproportion exhibited a rising trend (p<0.001). There were 3,306 in-hospital deaths (mortality of 2.55%), with lower mortality in the endovascular group (1.2% vs. 5.0%, p=0.008). The overall governmental expenditure on these procedures was U$ 238,010,096.51, and endovascular procedures were on average significantly more expensive than open surgery (U$ 1,932.27 vs. U$ 1,517.32; p=0.016). Conclusions Lower limb revascularizations were performed on the Brazilian Public Healthcare System with gradually increasing frequency from 2008 to 2019. Endovascular procedures were vastly more common and were associated with lower in-hospital mortality rates, but higher procedure costs.

Resumo Contexto A doença arterial periférica (DAP) é uma doença com alta morbidade global, afetando mais de 200 milhões de pessoas. Objetivos Neste estudo, analisamos o tratamento cirúrgico para DAP no sistema público de saúde do Brasil no período de 12 anos, com base em dados publicamente disponíveis. Métodos O estudo foi conduzido a partir da análise de dados disponíveis na plataforma do Departamento de Informática do Sistema Único de Saúde (DATASUS), do Ministério da Saúde, avaliando a distribuição da técnica cirúrgica utilizada, a mortalidade e o custo ao longo dos anos. Resultados Um total de 129.424 procedimentos foram analisados (para claudicantes e isquemia crítica, em proporção desconhecida). A maiora dos procedimentos foi via endovascular (65,49%), com tendência de aumento nessa desproporção (p < 0,001). Houve 3.306 mortes intra-hospitalares (mortalidade de 2,55%) com menor mortalidade no grupo endovascular (1,2% vs. 5,0%; p = 0,008). O investimento governamental total para esses procedimentos foi de US$ 238.010.096,51, e os procedimentos endovasculares foram significativamente mais caros que a cirurgia aberta convencional (US$ 1.932,27 vs. US$ 1.517,32; p = 0,016). Conclusões No sistema público de saúde brasileiro, as revascularizações de membros inferiores ocorreram com frequência crescente entre 2008 e 2019. Os procedimentos endovasculares foram mais comuns e relacionados a menor mortalidade intra-hospitalar, mas a maiores custos.

Mapeando a área de pensamento social no Brasil: uma análise preliminar de sua produção em artigos / Mapping the research field of social thought in Brazil: a preliminary analysis of its production in articles / Mapeando el área del pensamiento social en Brasil: un análisis preliminar de su producción en artículos

Este artigo busca responder a alguns dos desafios de sistematização, indexação e divulgação de variados documentos acadêmicos da área de pensamento social no Brasil pela Biblioteca Virtual do Pensamento Social (BVPS). Argumentamos que a importância da discussão sobre preservação digital para a BVPS cumpre dois objetivos: o de disponibilizar documentos digitalizados a um público mais amplo e o de mapear a produção contemporânea da área, com intuito de criar uma memória intelectual. Neste artigo, nos deteremos sobretudo no segundo objetivo, tendo em vista definir bem como disponibilizar ao público da biblioteca os critérios de seleção e organização do acervo. Dentro dos limites do recorte proposto, por meio de redes de acoplamento bibliográfico, cocitação e mapas semânticos, apresentaremos aqui uma análise preliminar da produção de artigos na área de pensamento social no Brasil. A atual pesquisa é fundamental para a definição das próximas etapas de ampliação do conteúdo da biblioteca, notadamente a definição de novos seletores de busca, a integração de novos autores e autoras à seção Intérpretes e a indexação de trabalhos com temáticas e abordagens caras à área de pensamento social no Brasil.

This article seeks to respond to some of the challenges of systematization, indexing and dissemination of various academic documents in the field of social thought in Brazil by the BVPS ­ Biblioteca Virtual do Pensamento Social (Virtual Library of Social Thought). We argue that the importance of the discussion on digital preservation for the BVPS fulfills two objectives: that of making digitized documents available to a wider audience and that of mapping contemporary production in that field in order to create an intellectual memory. In this article, we will focus mainly on the second objective, in order to define as well as make available to the library public the selection and organization criteria of the collection. Within the limits of the proposed clipping, we will present here a preliminary analysis of the production of articles in the field of social thought in Brazil through networks of bibliographic coupling, co-quotation and semantic maps. The current research is fundamental for the definition of the next steps to expand the content of the library, notably the definition of new search options the integration of new authors in the section Interpreters and the indexing of works containing important themes and approaches for the area of social thought in Brazil.

A informação pública, garantida por lei no Brasil, é base para a geração de conhecimento adaptativo em situações adversas, como a extrema vulnerabilidade socioambiental e seus impactos na saúde humana. O presente artigo avalia a transparência da informação pública nas áreas de saúde humana (com foco no Sistema Único de Saúde ­ SUS), mudanças produtivas (uso do solo) e mudanças climáticas (chuva e temperatura), utilizando dados de 5.570 municípios brasileiros, ao longo dos últimos 20 anos. A experiência da construção de uma base nacional de dados (Data Lake) a partir de informações disponibilizadas em bases públicas (ou público-privadas) ­ DATASUS, MapBiomas, Instituto Nacional de Meteorologia (Inmet) e Hidroweb da Agência Nacional de Águas (ANA) ­ confirmou que, na prática, a acessibilidade da informação pública no Brasil apresenta entraves importantes. Incluímos recomendações sobre como ela pode ser aprimorada para tornar os direitos de acesso à informação uma realidade mais concreta para o cidadão brasileiro.

The transparency of public information, a right that is entitled by law in Brazil, is the basis to generate adaptive knowledge in adverse situations, such as extreme socio-environmental vulnerability and its impacts on human health. This article evaluates the transparency of public information in three areas ­ i) human health, focusing on the Sistema Único de Saúde ­ SUS (Unified Health System); ii) productive changes (land use indicators); and iii) climate changes (rain and temperature indicators) ­ using data from all the 5,570 Brazilian municipalities over the last 20 years. The experience of building a national database (Data Lake) from available information in public (or public-private) databases ­ DATASUS, MapBiomas, Instituto Nacional de Meteorologia ­ Inmet (National Institute of Meteorology), and Hidroweb of the Agência Nacional de Águas ­ ANA (National Water Agency) ­ confirmed that, in practice, the accessibility of public information in Brazil suffers from significant shortcomings. We include some recommendations for and how it could be improved so that the access rights to information becomes a more concrete reality for the Brazilian citizen.

Spindle assembly checkpoint complex-related genes TTK and MAD2L1 are over-expressed in lung adenocarcinoma: a big data and bioinformatics analysis / 南方医科大学学报

OBJECTIVE@#To screen the key genes related to the prognosis of lung adenocarcinoma through big data analysis and explore their clinical value and potential mechanism.@*METHODS@#We analyzed GSE18842, GSE27262, and GSE33532 gene expression profile data obtained from the Gene Expression Omnibus (GEO). Bioinformatics methods were used to screen the differentially expressed genes in lung adenocarcinoma tissues and KEGG and GO enrichment analysis was performed, followed by PPI interaction network analysis, module analysis, differential expression analysis, and prognosis analysis. The expressions of MAD2L1 and TTK by immunohistochemistry were verified in 35 non-small cell lung cancer specimens and paired adjacent tissues.@*RESULTS@#We identified a total of 256 genes that showed significant differential expressions in lung adenocarcinoma, including 66 up-regulated and 190 down-regulated genes. Thirty-two up-regulated core genes were screened by functional analysis, and among them 29 were shown to significantly correlate with a poor prognosis of patients with lung adenocarcinoma. All the 29 genes were highly expressed in lung adenocarcinoma tissues compared with normal lung tissues and were mainly enriched in cell cycle pathways. Seven of these key genes were closely related to the spindle assembly checkpoint (SAC) complex and responsible for regulating cell behavior in G2/M phase. We selected SAC-related proteins TTK and MAD2L1 to test their expressions in clinical tumor samples, and detected their overexpression in lung adenocarcinoma tissues as compared with the adjacent tissues.@*CONCLUSIONS@#Seven SAC complex-related genes, including TTK and MAD2L1, are overexpressed in lung adenocarcinoma tissues with close correlation with the prognosis of the patients.
