Objectives To analyze the effect of improved oven for defluorination in coal-burning endemic fluorosis areas in China, and to provide evidence for the prevention and control of fluorosis. Methods Electronic databases including CNKI, CBM, VIP and CDMD-D (1989 to 2005), were searched. We also checked the reference lists of relevant articles. We selected relevant articles according to the predefined inclusion and exclusion criteria. The methodological quality was assessed . Data on room heat preservation and the effect of improved oven for defluorination were collected in the surveillance spots of Three Gorges Reservoir. Correlation analyses were conducted between the improved oven and its effect parameters. Results Twelve articles of low quality met the selection criteria, of which 9 were graded C and 3 were graded D in terms of the methodological quality. A negative correlation was found between the decreasing rate of normal oven use and the decreasing rate of dental fluorosis as well as of urine fluorine (Pearson correlation coefficient r = – 0.87, – 0.63, Plt;0.01, lt;0.05, respectively). Analysis also revealed a positive correlation between room heat preservation and the decreasing rate of dental fluorosis as well as of normal oven use (the two Spearman correlation coefficients and P values were the same: r = –1.00, Plt;0.01). Conclusion High-quality studies on the effect of improved oven for defluorination in China are not available. Based on the current evidence, the improved oven for defluorination and the correct use, maintenance and house rebuilding for heat preservation may help to prevent fluorosis.
With nearly four decades of progress in healthcare-associated infection prevention and control in China, the national quality control efforts in this field have been ongoing for the past ten years, advancing rapidly with significant achievements. Over the last decade, the team of infection control professionals involved in quality management and control in China has consistently expanded, accompanied by an enhancement of their skills. Management capabilities have steadily grown, and operational mechanisms have been continuously refined. As public hospitals transition into a new phase of high-quality development, emphasizing refined management models and intrinsic development of medical quality, it becomes crucial to further fortify the foundation and foster innovation in infection control work to ensure quality. This article provides an overview of the establishment and implementation of the National Center for Quality Control of Infection Prevention and Control, examines the current shortcomings and challenges in the field, and collectively explores the positioning and direction of the development of quality control efforts for infection prevention and control in China.
ObjectiveTo construct a rapid screening tool for the donor of heart dead organ donation (donation after circulatory death, DCD) in the background of novel coronavirus (SARS-CoV-2) infection.MethodsBased on literature analysis and core group discussion, two rounds of expert consultation were carried out by Delphi method to establish dimension and index.ResultsThe screening tool included 3 dimensions, including epidemiological history, hospital exposure history, and clinical manifestations, with 15 entries. The mean of the two rounds of expert authority coefficient was 0.757 and 0.768, and the effective recovery rate of the expert consultation questionnaire was 88% and 100%, respectively. The second round dimension and index coordination coefficients was 0.417 and 0.319, respectively. The content validity of the questionnaire was 0.91.ConclusionsThe DCD liver transplant donor's new rapid screening tool for SARS-CoV-2 infection is scientific and reliable. During the epidemic period, the DCD liver transplant donor risk screening tool is of great significance to the prevention and control of liver transplantation risk.
Carbapenemase producing Enterobacteriaceae (CPE) has emerged as a significant global public health challenge and placing infected patients at risk of potentially untreatable infections. When resistance to carbapenems occurs, there are often few alternative treatments available. Numerous international guidelines have performed systematic and evidence review to identify new strategies to prevent the entry and spread of CPE in healthcare settings. Several key strategies have been shown to be highly effective. Firstly a new strategy that is proven to be effective is the early identification of the CPE carrier patients through active surveillance cultures. While waiting for the screening results, suspected CPE carriers will be put on preemptive isolation in single room and healthcare worker will at the same time practice contact precautions. The active surveillance culture and prompt preemptive isolation will limit the entry and spread of CPE from getting into hospital. Secondly, it is of utmost importance to incorporate enforcement of the basic infection prevention and control best practices in the hospital including, full compliance to hand hygiene, appropriate use of personal protective equipment, execute antibiotic stewardship program to control abuse of antibiotics, effective environmental cleaning and decontamination, staff education and feedback, as well as surveillance of healthcare-associated infections. Such a holistic approach has been shown to be effective in inhibiting CPE from gaining foothold in the hospital.
The coronavirus disease 2019 (COVID-19) epidemic has had a serious impact in the world. In the absence of vaccines and therapeutic drugs, disinfection has become an important technical means to block the spread of the virus. By analyzing the characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we studied a series of disinfection technologies for COVID-19. During the outbreak of COVID-19, Jinan Second Center for Disease Control and Prevention disinfected the houses of the cases to be investigated in a community. The effectiveness of the disinfection technology was verified through the process of disinfection preparation, sampling before disinfection, field disinfection, sampling after disinfection and evaluation of disinfection effect. Compared the data before and after disinfection, the killing rate of the total bacterial colonies in the air and on the surface of the object was more than or equal to 90%, and no SARS-CoV-2 was detected after disinfection. The results show that the disinfection effect of the disinfection technology meets the standard. Finally, through the analysis of the wrong way of disinfection and the harm of over disinfection, the importance of scientific disinfection and precise disinfection are emphasized, and the research has a good guiding value for prevention and control of the epidemic.
Novel coronavirus pneumonia is a new type of respiratory infectious disease that has rapidly spread in many countries or regions around the world. The World Health Organization (WHO) named it “coronavirus disease 2019 (COVID-19)”. Glucocorticoids (GC) have certain application value in patients with COVID-19, but they need to be used with caution and strict indications and dosage. Application of large doses of GC can also cause osteonecrosis of femoral head (ONFH). On the basis of the latest literature and evidence-based medical evidence on the fight against COVID-19 epidemic and steroid ONFH diagnosis and treatment, the Bone Circulation and Osteonecrosis Professional Committee, Shockwave Medical Specialty Committee of Chinese Research Hospital Association organized Chinese bone necrosis related experts to jointly write this consensus, focusing on the prevention strategy and the protective management measures in the ONFH diagnosis and treatment process during the prevention and control of COVID-19, which can provide reference for hospitals at all levels to carry out early prevention and treatment of ONFH.
Objective To understand the influence of organisational support and professional identity of hospital infection prevention and control (HIPC) practitioner in public hospitals. Methods HIPC practitioner of the public medical institutions secondary level and above in Neijiang City, Sichuan Province were used as the research object. A questionnaire survey was used to analyze their organizational support and professional identity in May 2022, to compare the differences in organizational support and professional identity among HIPC practitioner with different positions, working ages, and majors, and analyze the correlation between organizational support and professional identity among HIPC practitioner. Results A total of 90 valid questionnaires were retrieved from investigation. The average scores for organizational support and professional identity among HIPC practitioner were (3.409±0.625) and (2.518±0.504) points. Among them, the organizational support of intermediate professional title personnel [(3.155±0.785) points], personnel with 5-10 years of service [(3.071±0.696) points], and clinical physicians [(3.342±0.860) points] were the lowest; the professional identity of personnel with intermediate professional titles [(2.357±0.477) points], those with more than 10 years of service[(2.431±0.454) points], and other professionals [(2.471±0.260) points] were the lowest. The Pearson correlation analysis results showed that there was a positive correlation between organizational support and professional identity (r=0.490, P<0.05), self-identity and work support (r=0.364, P<0.05), and environmental identity and relationship interests (r=0.698, P<0.05). Conclusions Due to the low level of organizational support, there is a decrease in professional identity and significant job burnout, which in turn leads to an increase in the turnover rate of infection control professionals. Therefore, it is necessary to enhance the sense of organizational support for specialized personnel in infection control to promote their professional identity and stabilize the infection control team. Suggest providing necessary support at the organizational level and self-improvement at the individual level.

ObjectiveTo study the relationship between macular pigment optical density (MPOD) and serum concentration of lutein and zeaxanthin in an adult population. MethodsTwenty patients with mild cataract and 39 healthy subjects were enrolled in this study, including 15 males and 44 females. The average age was 43.75 years. Fifty-three subjects were non-smokers and 6 male subjects were smokers. Two subjects preferred meat diet, 22 preferred meat-less diet, and 35 have balanced diet. MPOD was measured using heterochromatic flicker photometry at 0.25, 0.5, 1.0 and 1.75 degrees, and serum concentration of lutein and zeaxanthin was measured using high-performance liquid chromatography. The relationship between MPOD and serum concentration of lutein and zeaxanthin was analyzed. The differences of serum lutein and zeaxanthin between different gender, smokers and non-smokers and subjects with different dietary pattern were also analyzed. ResultsMPOD at 0.25, 0.5, 1.0 and 1.75 degrees were 0.59, 0.48, 0.34 and 0.18, and the average concentration of lutein and zeaxanthin were (0.45±0.16) μmol/L and (0.11±0.04) μmol/L respectively. Serum concentration of lutein and zeaxanthin in males were slightly higher than that in females, but it was not statistically significant (t=1.13, 0.86; P=0.27, 0.40). The differences of serum lutien and zeaxanthin between smokers and non-smokers (t=-0.15, -0.11; P=0.87, 0.91), among subjects of 3 dietary patterns groups were not statistically significant (Flutein=3.87, 4.05, 0.18; P=0.83, 0.81, 0.99. Fzeaxanthin＝0.99, 1.51, 0.52; P＝0.85, 0.68, 0.72). There was no correlation between MPOD and serum concentration of lutein (r=-0.06,-0.02,-0.07,0.03;P>0.05)and zeaxanthin(r=0.02,0.12,0.09,0.11;P>0.05). ConclusionMPOD was not statistically significantly correlated with serum concentration of lutein and zeaxanthin in the studied population.
