Identification of Early Warning Signals of Infectious Diseases in Hospitals by Integrating Clinical Treatment and Disease Prevention

The global incidence of infectious diseases has increased in recent years,posing a significant threat to human health.Hospitals typically serve as frontline institutions for detecting infectious diseases.However,accurately identifying warning signals of infectious diseases in a timely manner,especially emerging infectious diseases,can be challenging.Consequently,there is a pressing need to integrate treatment and disease prevention data to conduct comprehensive analyses aimed at preventing and controlling infectious diseases within hospitals.This paper examines the role of medical data in the early identification of infectious diseases,explores early warning technologies for infectious disease recognition,and assesses monitoring and early warning mechanisms for infectious diseases.We propose that hospitals adopt novel multidimensional early warning technologies to mine and analyze medical data from various systems,in compliance with national strategies to integrate clinical treatment and disease prevention.Furthermore,hospitals should establish institution-specific,clinical-based early warning models for infectious diseases to actively monitor early signals and enhance preparedness for infectious disease prevention and control.

Overview of the plague in the late Ming Dynasty and its prevention and control measures

The plague of the late Ming Dynasty(15511644 C.E.)was long lasting,affected a wide range of the population,and had serious consequences.The purpose of this study is to review the medical system in place at the time and the measures instituted to prevent and control the plague during the late Ming Dynasty.Information on the history of the Ming Dynasty(13681644 C.E.),local chronicles,and related research literature were consulted and analyzed in terms of duration,geographical area,and other dimensions of the epidemic.Because of the abnormal climate,wide range of natural disasters,and the impact of war,the epidemic spread over a wide area during the late Ming Dynasty.The government’s epidemic prevention measures were affected by war and other factors,resulting in poor control of the outbreak.However,in terms of the medical system in place during the Ming Dynasty,some of the thinking and methods of prevention and control of the plague were historical and progressive.Some outstanding physicians such as Wu Youke(15821652 C.E.)appeared during this period.His theory of plague prevention and control had a profound influence on the formation and development of pestilence deterrence in later generations.In the late Ming Dynasty,rich experiences and measures of prevention and control were accumulated in the struggle against the plague.These methods and experiences also have a significant,positive guiding influence on the prevention and control of plague in the present day.

Analysis of CDC’s Role in Public Health Emergencies

Objective:To explore the role of the Centers for Disease Control and Prevention(CDC)in public health emergencies.Methods:The details of 12 public health events that occurred between January 2021 to December 2022 were analyzed to explore the roles of the CDC.Results:There were 160 patients involved in 10 public health events in 2021 and 48 patients involved in 2 public health events in 2022.Besides,the proportion of school public health events in 2022 was 0%,which was lower than in 2021,which was 80%(P<0.05).99.38%of patients during public health events were sent to the hospital promptly in 2022,which was higher than that in 2021,which was 81.25%(P<0.05).Furthermore,the average time taken for the CDC to control public health events in 2022 was 20.11±1.62 hours,and the average time taken to send inspection reports was shorter than that in 2021.The public satisfaction score was also higher in 2022 compared to 2021(P<0.05).Conclusion:The role of the CDC is to control infectious diseases.Therefore,it is important to pinpoint the existing problems in the strategies implemented by the CDC so that more improvements can be made to better prevent infectious diseases.

Remote sensing and geographic information systems in the spatial temporal dynamics modeling of infectious diseases

Similar to species immigration or exotic species invasion,infectious disease transmis-sion is strengthened due to the globalization of human activities. Using schistosomiasis as an exam-ple,we propose a conceptual model simulating the spatio-temporal dynamics of infectious diseases. We base the model on the knowledge of the interrelationship among the source,media,and the hosts of the disease. With the endemics data of schistosomiasis in Xichang,China,we demonstrate that the conceptual model is feasible; we introduce how remote sensing and geographic information systems techniques can be used in support of spatio-temporal modeling; we compare the different effects caused to the entire population when selecting different groups of people for schistosomiasis control. Our work illustrates the importance of such a modeling tool in supporting spatial decisions. Our mod-eling method can be directly applied to such infectious diseases as the plague,lyme disease,and hemorrhagic fever with renal syndrome. The application of remote sensing and geographic informa-tion systems can shed light on the modeling of other infectious disease and invasive species studies.

The strategic framework of tuberculosis control and prevention in the elderly:a scoping review towards End TB targets

With the rapid pace of population ageing,tuberculosis(TB)in the elderly increasingly becomes a public health challenge.Despite the increasing burden and high risks for TB in the elderly,targeted strategy has not been well understood and evaluated.We undertook a scoping review to identify current TB strategies,research and policy gaps in the elderly and summarized the results within a strategic framework towards End TB targets.Databases of Embase,MEDLINE,Global health and EBM reviews were searched for original studies,review articles,and policy papers published in English between January 1990 and December 2015.Articles examining TB strategy,program,guideline or intervention in the elderly from public health perspective were included.Nineteen articles met the inclusion criteria.Most of them were qualitative studies,issued in high-and middle-income countries and after 2000.To break the chain of TB transmission and reactivation in the elderly,infection control,interventions of avoiding delay in diagnosis and containment are essential for preventing transmission,especially in elderly institutions and aged immigrants;screening of latent TB infection and preventive therapy had effective impacts on reducing the risk of reactivation and should be used less reluctantly in older people;optimizing early case-finding with a high index of suspicion,systematic screening for prioritized high-risk groups,initial empirical and adequate follow-up treatment with close monitoring and evaluation,as well as enhanced programmatic management are fundamental pillars for active TB elimination.Evaluation of TB epidemiology,risk factors,impacts and cost-effectiveness of interventions,adopting accurate and rapid diagnostic tools,shorter and less toxic preventive therapy,are critical issues for developing strategy in the elderly towards End TB targets.TB control strategies in the elderly were comprehensively mapped in a causal link pathway.The framework and principals identified in this study will help to evaluate and improve current program,develop targeted strategy,as well as raise more discussions on the research priority settings and policy transitions.Given the scarceness of policy and evaluated interventions,as well as the unawareness of shifting TB epidemiology and strategy especially in developing countries,the increasing need of a ready TB program for the elderly warrants further research.

雾化疫苗研究进展

近年来,随着黏膜疫苗及免疫技术的不断发展,针对呼吸道疾病免疫预防的雾化疫苗及相应雾化吸入免疫技术的报道与应用逐渐增多。雾化疫苗是通过雾化装置将液态和固态免疫原制成雾滴或气溶胶颗粒,以喷雾免疫或气溶胶免疫的形式进入人与动物呼吸道及肺部,并诱导机体产生保护性应答的疫苗。雾化免疫能更好地诱导黏膜免疫应答,同时避免了注射带来的疾病传播风险和疼痛。20世纪50年代鸡新城疫疫苗的喷雾免疫研究拉开了动物呼吸道免疫的序幕,随后开展了鸡传染性支气管炎疫苗的喷雾接种,目前很多禽用疫苗的喷雾免疫已被广泛使用。猪用疫苗的气溶胶免疫研究起步较晚,难度也更大。20世纪70年代末以来,逐步在猪瘟疫苗、猪胸膜肺炎放线杆菌疫苗及猪支原体肺炎疫苗上开展相应的气溶胶免疫研究。相比动物疫苗,人用疫苗的气溶胶免疫研究报道更多,主要集中在麻疹疫苗、结核疫苗和流感疫苗。2019年以来,新型冠状病毒肺炎疫苗的气溶胶免疫快速发展,目前在中国已被批准紧急使用。笔者就动物用及人用雾化疫苗研究现状进行系统陈述,总结分析了各类雾化疫苗的理化参数、安全性、体内趋向性、肺脏局部免疫应答、免疫接种效果,并提出未来在疫苗剂型与组份、雾化发生装置、雾化过程质控、免疫程序与效果评价等方面的研究需求。本综述可为后续相应的呼吸道黏膜疫苗研发提供参考。
