The Limits of the Intervention of Public Power in Individual Health Choices——From the Perspective of the Realization of the Right to Health in the Prevention and Control of Chronic Diseases

Noncommunicable chronic diseases have become the most important public health problem in the world today,so the focus of public health services should be shifted from the traditional area of communicable diseases to the prevention and control of chronic diseases.Since bad living habits are the most direct cause of chronic diseases,the most effective measure to prevent and control chronic diseases is to promote healthy lifestyles for the individual citizen.The theories of equal health opportunity,the right to health from the perspective of human rights,and determinants of a healthy society provide justified reasons for the intervention of public power in individual health choices.In the current legal system,the intervention of public power is limited to flexible measures such as health education,which shows respect for individual autonomy.However,it is inconsistent with the needs of current public health practice.We should expand diversified intervention means to encourage individuals to make healthy choices under the guidance of the management model.The“ladder of intervention”outlines a panoramic view of the intervention measures available.However,for the selection of specific measures,it is necessary to consider the public health objectives and the invasion of individual freedom,introduce the“legal reservation principle”and“proportionality principle”as policy analysis tools,and reasonably choose intervention measures at different levels on the ladder to properly handle the tension between public power and private rights.

Scientific and targeted prevention and control measures to optimize COVID-19 response

Since the outbreak of the COVID-19 pandemic,under the strong leadership of the Central Committee of the Communist Party of China and President Xi Jinping,China has made firm decisions to prioritize people's lives and health.Efforts have been made to avoid foreign imported infection and domestic rebound of COVID-19 cases;the“dynamic zero COVID”policy has been executed without wavering;and the prevention and control measures have been optimized and improved in response to changing circumstances,actively responding to the impact caused by multiple waves of COVID-19 surge globally.China has made extraordinary efforts to safeguard people's lives and health.Meanwhile,prevention and control measures were timely updated to coordinate with economic and social development.On November 10,the Standing Committee of the Central Political Bureau held a meeting to discuss the latest situation of the COVID-19 pandemic in China.Twenty measures(referred to as“the 20-point measures”)were officially announced to further optimize the COVID-19 response.The latest prevention and control measures involve the requirements and guidance for isolation at home,high-risk area delineation,nucleic acid testing,international inbound flights and travelers,vaccination rollout,medical resource preparedness,and protection for special places and vulnerable population.

Prevention and control measures to further optimize COVID-19 response

On November 11,2022,the Chinese government released the Scientific and Targeted Prevention and Control Measures to Optimize COVID-19 Response.Since that time,adjusted measures have been implemented throughout China,leading to major shifts in implementation of the national prevention and control strategy.On the basis of the current situation of the epidemic and the evolving SARS-Cov-2 variants,an additional 10 specifications(referred to as“the 10-point measures”)were officially released on December 7,2022,in an effort to further optimize the prevention and control measures.The latest adjustments pertain to the specification of:precise delineation of high-risk areas,nucleic acid testing scheme,isolation and health monitoring,restriction and lifting of high-risk areas,medicine supply,vaccination rollout among older people,health status of key populations,social functioning,and campus response.

The impact of accountability on local officials’behavior in the pandemic prevention and control in China based on utility maximization

Background:The COVID-19 pandemic is a public health crisis and an inspection of national governance systems and crisis response capabilities of countries globally.China has adopted a tough accountability system for officials and has succeeded in containing the spread of the pandemic.This study aimed to assess the impact of accountability on local officials’behavior in the pandemic prevention and control based on the official promotion tournament theory and utility maximization analysis framework.Methods:The panel data of 237 Chinese cities were extracted with local officials’characteristics,confirmed cases,Baidu migration index,Baidu search index according to city names,and data were excluded with local officials’relocation or sub-provincial cities between January 1,2020 and May 5,2020.Promotion gain and accountability cost were constructed by adopting promotion speed indicator,and the research hypotheses were assumed based on the utility maximization.It was the first time to apply the interaction model to empirically investigate the relationship between the promotion speed of local officials and the COVID-19 confirmed cases.Results:Our study showed that the promotion speed of provincial governors and mayors significantly affected the number of confirmed cases(β=−11.615,P<0.01).There was a significant interaction between the promotion speeds of provincial governors and mayors(β=−2594.1,P<0.01),indicating that they had a coordinated effect on the pandemic control.Additionally,mayors with different promotion speeds made a significant difference in controlling the imported cases and those who promoted faster better controlled the imported cases(β=−0.841,P<0.01).Mayors with full-time postgraduate education,titles,and majors in science and engineering had a better effect on controlling the number of confirmed cases.Conclusions:Our study provides evidence that the official accountability system has played an important role in containing the pandemic,which suggests that local officials motivated by the accountability system would respond to the pandemic actively for higher utility.Furthermore,provincial governors and mayors have played a coordinated effect in pandemic control.The above evidences reveal that implementing the official accountability system could improve the government’s emergency management capability and the efficiency of pandemic control.Therefore,adopting a strict accountability system could be effective in pandemic containment globally,especially in centralized countries.

Enlightenment from the COVID-19 Pandemic:The Roles of Environmental Factors in Future Public Health Emergency Response

The coronavirus disease 2019(COVID-19)pandemic is challenging the current public health emergency response systems(PHERSs)of many countries.Although environmental factors,such as those influencing the survival of viruses and their transmission between species including humans,play important roles in PHERSs,little attention has been given to these factors.This study describes and elucidates the roles of environmental factors in future PHERSs.To improve countries’capability to respond to public health emergencies associated with viral infections such as the COVID-19 pandemic,a number of environmental factors should be considered before,during,and after the responses to such emergencies.More specifically,to prevent pandemic outbreaks,we should strengthen environmental and wildlife protection,conduct detailed viral surveillance in animals and hotspots,and improve early-warning systems.During the pandemic,we must study the impacts of environmental factors on viral behaviors,develop control measures to minimize secondary environmental risks,and conduct timely assessments of viral risks and secondary environmental effects with a view to reducing the impacts of the pandemic on human health and on ecosystems.After the pandemic,we should further strengthen surveillance for viruses and the prevention of viral spread,maintain control measures for minimizing secondary environmental risks,develop our capability to scientifically predict pandemics and resurgences,and prepare for the next unexpected resurgence.Meanwhile,we should restore the normal life and production of the public based on the“One Health”concept,that views global human and environmental health as inextricably linked.Our recommendations are essential for improving nations’capability to respond to global public health emergencies.

Effects of policies and containment measures on control of COVID- 19 epidemic in Chongqing

BACKGROUND Coronavirus disease 2019(COVID-19)is an emerging,rapidly evolving disease that spreads through the respiratory system and is highly contagious.In March 2020,the World Health Organization declared the COVID-19 outbreak a pandemic.In China,the pandemic was controlled after 2 mo through effective policies and containment measures.Describing the detailed policies and containment measures used to control the epidemic in Chongqing will provide a reference for the prevention and control of COVID-19 in other areas of the world.AIM To explore the effects of different policies and containment measures on the control of the COVID-19 epidemic in Chongqing.METHODS Epidemiological data on COVID-19 in Chongqing were prospectively collected from January 21 to March 15,2020.The policies and prevention measures implemented by the government during the epidemic period were also collected.Trend analysis was performed to explore the impact of the main policy measures on the effectiveness of the control of COVID-19 in Chongqing.As of March 15,the cumulative incidence of COVID-19 in Chongqing was 1.84/100000(576 cases)and the infection fatality rate was 1.04%(6/576).The spread of COVID-19 was controlled by effective policies that involved establishing a group for directing the COVID-19 epidemic control effort;strengthening guidance and supervision;ensuring the supply of daily necessities and medical supplies and equipment to residents;setting up designated hospitals;implementing legal measures;and enhancing health education.Medical techniques were implemented to improve the recovery rate and control the epidemic.Policies such as“the lockdown of Wuhan”,“initiating a first-level response to major public health emergencies”,and“implementing the closed management of residential communities”significantly curbed the spread of COVID-19.Optimizing the diagnosis process,shortening the diagnosis time,and constructing teams of clinical experts facilitated the provision of“one team of medical experts for each patient”treatment for severe patients,which significantly improved the recovery rate and reduced the infection fatality rate.CONCLUSION The prevention policies and containment measures implemented by the government and medical institutions are highly effective in controlling the spread of the epidemic and increasing the recovery rate of COVID-19 patients.

Interpretation of Information Security and Data Privacy Protection According to the Data Use During the Epidemic

COVID-19 has swept the whole our country and the world in the beginning of 2020.31 provinces and municipalities across the country have launched the first-level response to major public health emergencies since January 24,and China has carried out intensive epidemic control.It is critical for effectively responding to COVID-19 to collect,collate and analyze people’s personal data.What’s more,obtaining identity information,travel records and health information of confirmed cases,suspected cases and close contacts has become a crucial step in epidemic investigation.All regions have made full use of big data to carry out personnel screening,travel records analysis and other related work in epidemic prevention and control,effectively improving the efficiency of epidemic prevention and control.However,data leakage,personnel privacy data exposure,and personal attack frequently occurred in the process of personnel travel records analysis and epidemic prevention and control.It even happened in the WeChat group to forward a person’s name,phone number,address,ID number and other sensitive information.It brought discrimination,telephone and SMS harassment to the parties,which caused great harm to individuals.Based on these,lack of information security and data security awareness and other issues were exposed.Therefore,while big data has been widely concerned and applied,attention should be paid to protecting personal privacy.It is urgent to pay more attention to data privacy and information security in order to effectively protect the legitimate rights of the people.Therefore,measures can be taken to achieve this goal,such as improving the relevant legal system,strengthening technical means to enhance the supervision and management of information security and data protection.

Factors influencing the tobacco control policy process in Egypt and Iran:a scoping review

Introduction:Tobacco control policy is essential for addressing the growing tobacco consumption seen in the Eastern Mediterranean Region,the single greatest preventable contributor to the non-communicable disease epidemic.Egypt and Iran have had varied success in using policy to combat this issue.The study aims to identify and compare the factors which have influenced different stages of the policy process-evidence generation,development and implementation.Methods:A scoping review was conducted with a systematic search of 7 databases which was conducted along with searches of Google Scholar,and the World Health Organisation and Eastern Mediterranean Regional Office websites to identify influencing factors at each stage of the policy process.Results:Twenty-seven relevant articles were identified from the literature search.Factors identified as influencing tobacco control policy in these countries were lobbying by the tobacco industry,the rise of water-pipe smoking,lack of political commitment and the lack of resources to for policy implementation.Iran was found to be leading Egypt on all three areas of the policy process.Implementation was found to be the most pivotal part of the policy process and the area in which Egypt was weakest compared to Iran.Conclusion:This study addresses a gap in knowledge concerning tobacco control in the Middle East and has identified multiple factors which are potentially slowing the process of enforcing policy to address tobacco consumption.Iran is the regional leader for tobacco control and it is important for Egypt to assess the transferability of its tactics and immediately start implementing measures to control tobacco use.

Preventive Control for Power System Transient Security Based on XGBoost and DCOPF with Consideration of Model Interpretability

This paper proposes a new approach for online power system transient security assessment(TSA)and preventive control based on XGBoost and DC optimal power flow(DCOPF).The novelty of this proposal is that it applies the XGBoost and data selection method based on the 1-norm distance in local feature importance evaluation which can provide a certain model interpretability.The method of SMOTE+ENN is adopted for data rebalancing.The contingency-oriented XGBoost model is trained with databases generated by time domain simulations to represent the transient security constraint in the DCOPF model,which has a relatively fast speed of calculation.The transient security constrained generation rescheduling is implemented with the differential evolution algorithm,which is utilized to optimize the rescheduled generation in the preventive control.Feasibility and effectiveness of the proposed approach are demonstrated on an IEEE 39-bus test system and a 500-bus operational model for South Carolina,USA.
