Objective To analyze the current situation of healthcare-associated infection (HCAI) management of fever clinics among different levels of medical institutions in Wuhan, and to provide a scientific basis for improving hospital infection management. Methods In January 2023, a network questionnaire survey was conducted on medical institutions with fever clinics in Wuhan. Results A total of 72 medical institutions were investigated, of which 58.33% had CT, and 48.61% had fever clinics for children. The total qualified rate of HCAI management was 78.28%. The qualified rates of four primary indicators, including hospital management, diagnosis and treatment environment protection, training and education, and implementation of infection control measures, were 82.27%, 71.49%, 75.93%, and 81.31%, respectively. There were statistical differences among different levels of medical institutions (all P<0.01). Among the 13 secondary indicators, the qualified rates of 7 indicators were more than 80%, with the highest being medical item management (93.06%), medical waste disposal (89.72%), and personnel management (83.33%), and the lowest being facilities and equipment (66.32%), and patients and accompanying personnel education (66.67%). Among the 65 tertiary indicators, 30 had a pass rate great than 80%. Conclusion Wuhan actively promotes the construction of fever clinics in medical institutions, and the overall situation of HCAI management is good. However, there are still some problems to varying degrees, especially in the layout procedures, hand hygiene, and staff training of fever clinics in secondary and lower medical institutions, which should be further strengthened.

OBJECTIVE To optimize the honey processing technology of Phellinus igniarius. METHODS The key factors of honey processing technology of P. igniarius （honey-water ratio， the mass ratio of honey-water to P. igniarius， the frying temperature and the frying time） were investigated by orthogonal test combined with analytic hierarchy process to determine the optimal technological parameters， using the internal quality （the contents of ergosterol， protocatechuic aldehyde and protocatechuic acid） and appearance traits as evaluation indexes. RESULTS The optimal process of honey-roasting P. igniarius was to take raw P. igniarius （1 cm3 square block）， add the appropriate amount of auxiliary materials （with 25 kg of refined honey and water for every 100 kg of P. igniarius）， mix well， moisten for 2 h until the auxiliary materials were completely absorbed； put it in a frying container， fry at the frying temperature of 130-140 ℃ for 5 min； take it out， put it in an oven at 50 ℃ for 2 h； take it out， and let it cool. The RSD of the results of three validation experiments was 0.68%. CONCLUSIONS The optimized honey processing technology of P. igniarius is stable and feasible.

Objective:To investigate the effect of long-term oral aspirin on the changes in the aneurysm sac and persistent type Ⅱ endoleak after endovascular aortic repair (EVAR) of infrarenal abdominal aortic aneurysms based on propensity score-matched analysis.Methods:A retrospective cohort study was used to analyze the clinical data of 133 patients with infrarenal abdominal aortic aneurysms treated with EVAR from January 2019 to December 2021 in the Department of Vascular Surgery, Nanjing Drum Tower Hospital. There were 113 males and 20 females, aged (74.8±7.2) years (range: 59 to 95 years). Patients were divided into the group receiving aspirin ( n=80) and the group not taking aspirin ( n=53) based on whether they took aspirin regularly for a long time after surgery. The two groups were matched in a 1∶1 ratio using propensity score matching and the caliper value was 0.05. Cumulative probability curve was plotted using the Kaplan-Meier method and the Log-rank test was used to compare the differences in primary endpoint events (enlargement of the aneurysm sac, occurrence of persistent type Ⅱ endoleak) and secondary endpoint events (adverse cardiovascular events and clinically relevant bleeding events) between the two groups. Results:The follow-up time was (38.4±11.8) months (range: 30 to 58 months). Among the 133 patients, a total of 25 cases (18.8%) suffered enlargement of the aneurysm sac, including 20 cases in the group receiving aspirin and 5 cases in the group not taking aspirin; 35 cases (26.3%) suffered persistent type Ⅱ endoleak, including 26 cases in the group receiving aspirin and 9 cases in the group not taking aspirin. Adverse cardiovascular events occurred in 11 cases (8.3%) and clinically relevant bleeding events were reported in 5 cases (3.8%). A matched cohort was established after propensity score matching, resulting in 32 cases per group. The survival analysis found that the rate of aneurysm sac enlargement was significantly higher in the group receiving aspirin than that in the group not taking aspirin (Log-rank test: P=0.010), and the incidence of persistent type Ⅱ endoleak was significantly higher than that in the group not taking aspirin (Log-rank test: P=0.019). The incidence of adverse cardiovascular events and clinically relevant bleeding events were not significantly different in two groups (Log-rank test: P=0.061, P=0.286). Conclusions:The risk of aneurysm sac expansion and persistent type Ⅱ endoleak were significantly higher in patients taking long-term aspirin after EVAR than in the group not taking asprin. Therefore, high-risk abdominal aortic aneurysm patients who are prone to aneurysm sac expansion should be evaluated in advance so that the risks and benefits of surgery can be comprehensively evaluated and treatment strategies can be optimized.

Objective:To analyze the disease burden of chronic kidney disease (CKD) in the Belt and Road countries and its change trend.Methods:It was a cross-sectional epidemiological study based on surveillance data. Data on age-standardized prevalence rate (ASPR) and age-standardized mortality rate (ASMR) of CKD were derived from the 2019 Global Burden of Disease Study. The annual percentage change (APC) was calculated to evaluate the ASPR trend of CKD from 1990 to 2019.Results:In 2019, the number of CKD cases and deaths in the Belt and Road countries was 426 million and 798 000, respectively, accounting for 61.1% and 55.9% of CKD cases and deaths worldwide. The ASPR and ASMR of CKD in China were 8.1% and 11.2 per 100 000 population, slightly lower than the global average. Countries in North America and Oceania had a higher burden of CKD, and European countries had a lower burden. In the etiology, hypertension and diabetes-related CKD morbidity and mortality accounted for 23.7% and 68.8% of total CKD morbidity and mortality, respectively. From 1990 to 2019, the ASPR of CKD increased in 150 countries (98.0%) and the fastest increase was observed in Morocco ( APC=1.52%). The hotspots with high ASPR of CKD were located in Belt and Road countries from Asia, South/North America and Oceania, and the hotspots with high ASMR were distributed in countries from Africa, South/North America and Oceania. The sociodemographic index and life expectancy were positively correlated with the ASPR of CKD ( r=0.409, P<0.001; r=0.361, P<0.001) , and negatively correlated with the ASMR of CKD ( r=-0.317, P<0.001; r=-0.391, P<0.001). Conclusions:Belt and Road countries have substantial disease burdens of CKD, and the prevalence rate of CKD is rising fast. Health cooperation among member states should be strengthened to jointly address the challenges posed by chronic diseases such as CKD.

Objective:To construct the evaluation index system of core competence of extracorporeal membrane oxygenation (ECMO) specialist nurses.Methods:Through literature search and analysis, an entry pool of the core competence evaluation index system for ECMO specialist nurses was initially formed, and 20 medical and nursing experts in acute and critical care and cardiovascular fields were selected for two rounds of correspondence from September to November 2022. According to experts' opinions, the evaluation indexes of core competence of ECMO specialist nurses were modified, and the analytic hierarchy process determined the weights of indexes at all levels.Results:A total of 20 questionnaires were sent out and 20 valid questionnaires were collected during each of the two rounds of expert correspondence consultation, with effective recovery rates of 100.00%. The expert authority coefficient of the second round was 0.86, and Kendall's harmony coefficient was 0.31 ( P<0.01). Finally, the evaluation index system of core competence of ECMO specialist nurses included five primary indexes (clinical professional ability, communication and collaboration ability, nursing management ability, critical thinking ability, and professional development ability), 15 secondary indexes, and 53 tertiary indexes. Conclusions:The evaluation index system of core competence of ECMO specialist nurses constructed in this study is scientific and practical, providing a reference for evaluating ECMO specialist nurses' core competence.

Postpartum visit are maternal and child health services provided by primary care workers at the homes of postpartum women within one week after hospital discharge. However, China currently lacks detailed work guidelines and standardized protocols for such services, making it difficult to effectively assess the competency of postpartum visitors and improve service quality. This study reviewed 24 Chinese and English articles retrieved using a combination of subject and free terms, selected based on inclusion and exclusion criteria. The key components of postpartum visit competency were summarized into 3 dimensions: Health assessment, health education, and communication/coordination. While home visitors were generally capable of performing basic physical examinations and providing health education for mothers and newborns, they often lacked the ability to deliver more specialized maternal and infant care. Factors affecting the effectiveness of postpartum visit services included the personal characteristics, technical skills, and training of the visitors. Strategies to improve competencies involve reforming training methods, enhancing home visit skills, and standardizing procedures. Currently, there is a lack of comprehensive tools to assess postpartum visit competency.
