To explore the characteristics of big data of patients with allergic rhinitis, including the time, population and spatial distribution of allergic rhinitis in Beijing from 2016 to 2021, so as to provide reference for the prevention and treatment of this disease. Descriptive epidemiological methods were used to analyze the distribution (including gender, age and location)and trend of allergic rhinitis patients in 30 pilot hospitals from January 2016 to December 2021, T test and Kruskal-Wallis rank sum test were used to test the statistical differences. The results showed that the number of patients with allergic rhinitis in 30 hospitals increased year by year from 2016 to 2019, with an increase of 97.9%. In 2020, the number of patients decreased. In 2021, the number of visits returned to the pre-epidemic level (461 332); The number of patients with allergic rhinitis was the highest in September, with a seasonal index of 177.6%, while the lowest number was in February, accounting for only 47.2%; a significant difference was observed in the number of patients in different age groups(H=45 319.48, P<0.05), and patients under 15 years old accounted for the highest proportion(819 284 visits); There were significant differences between patients of different genders in the 45-59 year old group (t=-4.26, P<0.05).There were relatively more patients with allergic rhinitis in Dongcheng District(31.1%) than in Huairou District and Miyun District (0.4%). In conclusion, since 2016, the number of patients increased significantly, with a varied trend in different seasons. Most patients were children. There were more patients in the central urban area than in the outer suburbs.

Medical test results are indispensable and important tools in diagnosis and treatment services. It is necessary to promote the homogenization of test results first, because homogenization is the basis for mutual recognition of test results. Mutual recognition of medical test results can help share resources among medical institutions, provide more reliable test results for early prevention, screening and treatment of diseases, and reduce repeated tests, thus improving people's medical experience. In recent years, with the deepening of medical system reform and the promotion of graded diagnosis and treatment, governments have continuously introduced policies of mutual recognition of test results around country. However, homogenization is a prerequisite for mutual recognition of test results, with the emergence of intelligent medicine in the era of internet big data, opportunities and challenges coexist in the development of homogeneity management. In the future, the homogeneity of medical test results will present a trend of digitalization, automation, informatization and intelligence.

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.

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.

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.

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.

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.
