Application progress of predictive models in the prevention and control of myopia in children and adolescents / 国际眼科杂志(Guoji Yanke Zazhi)

In medical research,predictive models have been widely used to predict disease progression and identify high-risk populations in advance, especially in the prevention and diagnosis of chronic diseases. In ophthalmology, the predictive and diagnostic models for fundus diseases such as age-related macular degeneration and diabetic retinopathy have demonstrated expert-level accuracy. However, the application of predictive models is still in the exploratory stage as for myopia prevention and control. The establishment of a predictive model is helpful to identify the high-risk myopic children in advance, so that preventive measures such as adequate outdoor activities and reducing near work can be taken in time, which is of great significance to prevent or slow down the occurrence and development of myopia. Because the mechanism of myopia has not been fully elucidated, there are still challenges and limitations in the selection of application objects, predictors and predictive outcomes. This paper reviews the research progress of different types of myopia predictive models in order to provide reference for further development and improvement.

Status risk factors and prevention and control strategies of familial aggregation of Helicobacter pylori infection / 公共卫生与预防医学

Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ2=9.719, P=0.008), marital status (χ2=8.496, P=0.014), occupations (χ2=19.462, P2=5.457, P=0.019), previous Hp test results (χ2 =4.131, P=0.042) and test results after treatment (χ2=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.

Finding a way of life education with Chinese characteristics and making up for the shortcomings of life education, which should become a major issue for the in-depth study of COVID-19 epidemic prevention and control in China. Marx’s view of life is a correct and scientific view of life, which is not only the guiding ideology of life education, but also the important resources for life education. While criticizing the views of life and death based on the western philosophy of life, it can also overcomes the limitations of Chinese traditional view of life. In the epidemic prevention and control, the in-depth study of Marx’s view of life will help to promote the practice of life education, enable people to establish a correct and scientific view of life and obtain the life sublimation in life practice.

Advances in peripheral defocus and myopia prevention and control / 国际眼科杂志(Guoji Yanke Zazhi)

The global prevalence of myopia is increasing year by year, leading to many ocular health issues and social problems. In recent years, it has been confirmed that peripheral defocus is closely related to the occurrence and development of myopia. Alteration of the state of peripheral defocus can significantly influence the progression of myopia and emmetropization, but the exact mechanisms are still unclear. At present, there is no method that can completely control myopia. Nowadays, the main controlling methods, including orthokeratology lens, peripheral defocus lens and multi-focal soft lens, have been confirmed to be closely related to peripheral defocus. In this paper, we will review and summarize the development and effect of these peripheral defocus relating control methods. In addition, the researches on the related mechanisms of peripheral retinal defocus and myopia prevention and control at home and abroad are reviewed, as well as the potential mechanisms of peripheral defocus, with a view to further improving the controlling effects of existing methods, developing new prevention and control methods and reducing the incidence and progression of myopia.

Application of metagenomic next-generation sequencing in prevention and control of infection in solid organ transplantation / 器官移植

Organ transplantation has become an effective treatment for multiple end-stage diseases. However, the recipients of organ transplantation need to take immunosuppressive drugs for a long time after operation, which leads to low immune function and relatively high incidence of bacterial, viral and fungal infections. Traditional microbial detection methods, such as pathogen culture, immunological detection and polymerase chain reaction, have been widely applied in infection detection, whereas these methods may cause problems, such as long detection time and presumed pathogens. Metagenomic next-generation sequencing has been widely adopted in infection prevention and control in organ transplantation in recent years due to high detection rate and comprehensive detection of pathogen spectrum. In this article, the application of metagenomic next-generation sequencing in the prevention and control of infection in solid organ transplantation was reviewed, aiming to provide reference for the diagnosis and treatment of transplantation-related infection.

Medidas poblacionales para la seguridad vial: más allá de la responsabilidad individual

Las lesiones causadas por el tránsito (LCT) se encuentran dentro de las principales causas de mortalidad y discapacidad a nivel mundial, hecho reflejado en el puesto que ocupan dentro de las primeras diez causas de vida ajustados por discapacidad, con importantes costos e impacto económico y social para las sociedades que las padecen. En 2004, la Organización Mundial de la Salud (OMS) lanzó el primer informe sobre prevención de LCT. Sin embargo, en años posteriores esa situación no mejoró, por lo cual las Naciones Unidas lanzó la Década de Acción para la Seguridad Vial (2011-2020), donde se invitaba a los gobiernos a diseñar e implementar acciones para reducir la carga asociada a este problema; entre estas se encuentra diseño y mejoramiento de vías, atención oportuna pos siniestro, control de la velocidad, medidas de control administrativo, diseño y mejoramiento de estándares vehiculares, entre otras. Las medidas basadas en enfoque poblacional han demostrado ser más poderosas que las medidas que inducen cambios de comportamiento individual.

Injuries caused by traffic (ICT) are among the main causes of mortality and disability worldwide, reflected in the fact that they occupy the first ten causes of disability adjusted life years with economic and social cost impacts for the societies that suffer from them. In 2004, the World Health Organization (WHO) released the first Prevention Report about ICT. Nevertheless, in subsequent years this situation has not improved, motivating the United Nations to launch the Decade of Action for Road Safety (2011-2020), where governments were invited to design and implement actions to reduce the burden associated with this problem: designing and improving of roads, increasing timely post-crash care, speed control, administrative control measures, designing and improving vehicle safety standards, among others. Population-based measures have been shown to be more powerful than measures that induce individual behavior changes.

Objective: To explore the present situation and epidemiological characteristics of pesticide poisoning in Chengdu City from 2012 to 2021, and to provide scientific evidence for further prevention and control. Methods: In January 2022, the pesticide poisoning report cards of Chengdu City from 2012 to 2021 were collected from the China Disease Control and Prevention Information System. The data of the report card was reorganized and the distribution characteristics of pesticide poisoning such as time, region, gender, age and pesticide types were analyzed. Results: 14326 cases of pesticide poisoning were reported in Chengdu City from 2012 to 2021, 651 deaths, and the fatality rate was 4.54%. The cases of productive pesticide poisoning and unproductive pesticide poisoning were 504 and 13822, respectively. The fatality rates of productive and unproductive pesticide poisoning were 1.39% and 4.66%, which were significant different (χ(2)=11.99, P=0.001). The highest reported cases of pesticide poisoning was in 2013 (1779) and the lowest in 2021 (1047). The number of reported cases showed a downward trend year by year (t=-12.30, P<0.001), and the fatality rates also showed a downward trend year by year (χ(2)(trend)=25.48, P<0.001). The fluctuation range of unproductive pesticide poisoning cases in each month of the year was small, and the productive pesticide poisoning mainly occurred from May to August. The regions with the largest number of reported poisoning cases were Pengzhou (1620), Jianyang (1393), Jintang (1266) and Qionglai (1158). The high incidence of poisoning was among 25-54 years old (50.21%, 7193/14326). The fatality rate in the age group 75-96 years old was the highest (8.98%, 95/1058), and the fatality rates increased gradually with age (χ(2)(trend)=186.03, P<0.001). The pesticides causing poisoning were mainly insecticide (43.86%, 6284/14326) and herbicides (35.75%, 5121/14326). Herbicides paraquat had the highest fatality rate (9.54%, 286/2998) . Conclusion: Pesticide poisoning in Chengdu City is mainly unproductive poisoning. Health education should be carried out for key areas and people, and the control of highly toxic pesticides such as insecticide and herbicides should be strengthened.

Cross-sectional study on the use of masks among occupational groups with high-risk positions for overseas import and pollution transmission / 中华劳动卫生职业病杂志

Objective: To investigate the wearing of masks and the knowledge of masks among high-risk positions for overseas import and pollution transmission. Methods: From May 14 to 17, 2022, a convenient sampling method was used to conduct an online survey among 963 workers in high-risk positions for overseas import and pollution transmission in Beijing. The behaviors of individual use and wearing masks, the distribution and supervision of the unit, the knowledge of personal mask protection and the subjective feelings of wearing masks were analyzed. The χ(2) test and logistic regression model were used to analyze the influencing factors of the correct selection of masks. Results: The majority of the workers in high-risk positions for overseas import and pollution transmission were male (86.0%, 828/963), age concentration in 18-44 years old (68.2%, 657/963), and the majority of them had college or bachelor degrees (49.4%, 476/963). 79.4%(765/963) of the workers chose the right type of masks, female, 45-59 years old and high school education or above were the risk factors for correct selection of masks (P <0.05). Workers had good behaviors such as wearing/removing masks, but only 10.5% (101/963) could correctly rank the protective effect of different masks. 98.4% (948/963) of the workers believed that their work units had provided masks to their employees, and 99.1% (954/963) and 98.2%(946/963) of them had organized training and supervision on the use of masks, respectively. 47.4%(456/963) of the workers were uncomfortable while wearing masks. Conclusion: The overall selection and use of masks among occupational groups in high-risk positions for overseas import and pollution transmission in China need to be further standardized. It is necessary to strengthen supervision and inspection on the use of masks among occupational groups, and take improvement measures to improve the comfort of wearing masks.

Toxicity Reduction Measures of Herbal Medicines Causing Liver Injury and Role of Herbal Medicines in Preventing and Treating Liver Injury / 中国实验方剂学杂志

Chinese herbal medicines play a great role in disease prevention and treatment， while some may cause adverse effects on the human body after of long-term application. Liver injury， one of such adverse effects， is an important check item in the development of new Chinese medicines for clinical application and has become a major reason for the withdrawal of many listed drugs from the market. With the rising concern about the safety of Chinese herbal medicines， studies about liver injury caused by herbal medicines are increasing. Most of the studies focus on liver injury caused by Chinese herbal medicines or their ingredients. To improve the safety of Chinese herbal medicines， this paper summarizes the material basis and mechanisms of several Chinese herbal medicines that cause liver injury and the measures to reduce liver injury. These measures include reducing the dose and course of administration， changing the route of administration， and altering the dosage form， compatibility， and processing. In addition， this paper introduces the biological effects and mechanisms of single Chinese herbal medicines， Chinese medicine prescriptions， and active components in the prevention and treatment of liver injury. Furthermore， this paper proposes the safe dose and efficacy-toxicity boundary of Chinese herbal medicines that may cause liver injury by referring to the modern research on toxicity reduction， clarifies the mechanisms of toxicity reduction measures， and determines the material basis of liver injury induced by Chinese herbal medicines， which will ensure the safe application of herbal medicines in clinical practice. Finally， this paper suggests that efforts should be made to strengthen the clinical research on the prevention and treatment of liver injury and elucidate the scientific connotation of the prevention and treatment of liver injury by Chinese herbal medicines by using modern science and technology， aiming to provide a scientific basis for the clinical prevention and treatment of liver injury.

Occupational stress, anxiety, and depression among grassroots disease control and prevention staff in Hebei Province: A qualitative comparative analysis based on fuzzy sets / 环境与职业医学

Background Grassroots center for disease control and prevention (CDC) staff undertake intensive work of disease prevention and control, and may be susceptible to occupational stress, anxiety, depression, and other health problems. Objective To understand the current situation of occupational stress, anxiety, and depression among grassroots CDC staff, and to identify potential risk factor configurations for occupational stress, anxiety, and depression using fuzzy set qualitative comparative analysis (fsQCA), so as to provide a basis for effective intervention. Methods The staff working in county/district-level CDCs in Hebei Province were the target population of the current study. Stratified random cluster sampling method was used to select 1860 staff members of the target population. A questionnaire of general situation, Job Content Scale, 7-item Generalized Anxiety Disorder Scale, and Patient Health Questionnaire-9 were used. Risk factor configurations associated with health outcomes of interest were identified by fsQCA3.0 software. Results The positive rates of occupational stress, anxiety, and depression were 42.69%, 44.25%, and 47.96%, respectively. Marital status was a necessary condition for occupational stress, anxiety, and depression in the grassroots CDC staff (the necessity values were 0.911, 0.939, and 0.933, respectively). There were two types of risk factor configurations for occupational stress: "self-improvement" and "disease burden"; the risk factor configurations for anxiety were "disease burden" and "economic-disease burden"; while the risk factor configurations for depression were "disease burden", "economic-disease burden", and "self-improvement". The overall consistency scores of occupational stress, anxiety, and depression were 0.941, 0.820, and 0.774, respectively. Regarding outstanding components, "self-improvement" included pressure of job requirements and promotion, "disease burden" included impact of chronic illness on psychological state, and "economic-disease burden" included not only impact of chronic illness but also financial support for CDC staff. Conclusion All positive rates of occupational stress, anxiety, and depression are high among grassroots CDC staff in Hebei Province. Occupational stress, anxiety, and depression of grassroots CDC staff are the results of multiple influencing factors, so targeted intervention measures should be formulated.

Research progress of artificial intelligence in the prevention and control of myopia / 国际眼科杂志(Guoji Yanke Zazhi)

Myopia is one of the main causes of visual impairment. In recent years, the incidence of myopia has been increasing. Effective prevention and control of myopia is essential for maintaining patients' visual function and quality of life. With the continuous development of computer technology and big data acquisition, artificial intelligence(AI)is developing rapidly in the field of medical and health care. Machine learning and deep learning are gradually emerging in the field of myopia prevention and control. Through the AI model formed by training the diopter, axial length, color fundus photography, optical coherence tomography and other myopia-related data, with the help of remote medical platform, AI has played a positive role in the occurrence, progress prediction and monitoring of myopia, early warning of pathological myopia, prevention and treatment of myopia and ophthalmological telemedicine. This paper mainly reviews the research progress of AI in the field of myopia prevention and control, aiming to provide a new direction for the prevention and control of myopia in the future.

Construction of a social loss indicator system based on the perspective of epidemic prevention and control against the background of emerging major infectious diseases / 中华医院管理杂志

Objective:To construct a social loss indicator system based on the perspective of epidemic prevention and control against background of emerging major infectious diseases at the national, hospital, and individual levels, and to provide decision-making basis for public general hospitals to formulate prevention and control strategies for emerging major infectious diseases.Methods:Literatures published before December 23, 2020 were retrieved from CNKI, Wanfang, VIP, Web of Science, Google Scholar with such keywords as " infectious diseases" " public health emergencies" " social losses" " COVID-19" " evaluation". Then a preliminary social loss indicator system of public general hospitals for emerging major infectious diseases was constructed from such dimensions as country, hospital, and individual, by implementing literature analysis and expert consultation. Based on such a preliminary system, three questionnaires were designed for the country, hospitals, and individuals and the corresponding data were collected from December 25, 2021 to May 20, 2022. In the end, a factor analysis was made on the questionnaire data to optimize the social loss indicator system and determine the weights of each indicator.Results:The social loss indicator system consists of 14 level-1 indicators and 60 level-2 indicators. Level-1 indicators at country aspect consisted of government governance capacity, direct economic losses, social security, online public opinion, indirect economic losses, and international cooperation; indicators at hospital aspect consisted of hospital manpower, material resources, and information resources, hospital services, and hospital operations; indicators at the individual aspect consisted of physical health, psychological and social health, and external environment. Level-1 indicators of the highest weight at all aspects were social security, manpower, material and information resources, as well as physiological health. And the level-2 indicators of the highest weight were high medical expenses, overwork for staff other than doctors and nurses and medical insurance.Conclusions:The social loss indicator system for emerging major infectious diseases constructed in this study proves scientific and reasonable, helpful for the formulation of prevention and control strategies of public general hospitals.
