Objective To analyze the main epidemiological characteristics of fungal infection in this hospital in the past 7 years,and to provide reference for clinical treatment and prevention and control strategies of fun-gal infection.Methods The fungal data and clinical data of related patients isolated from clinical samples in Peking Union Medical College Hospital from early January 2018 to the end of May 2024 were selected,and the main epidemiological characteristics of fungal infection in this hospital were identified and described through multi-angle statistical analysis.Results A total of 4 479 patients with filamentous fungal infection were en-rolled.The proportion of male patients[57.5％(2 576/4 479)]was higher than that of female patients[42.5％(1 903/4 143)],mainly distributed in internal medicine,Intensive Care Unit(ICU)and emergency de-partment,among which internal medicine accounted for the highest proportion[50.0％(2 241/4 479)].About 90.0％of the specimens were from the lower respiratory tract,in addition to specimens from skin and soft tis-sue,tissue,ear and blood culture.In terms of seasonal distribution,there are more patients in winter.The fun-gi were mainly composed of Aspergillus,Mucor,Cerdosporium,Fusarium and Penicillium,among which As-pergillus was the most abundant,accounting for 74.6％of the total.Aspergillus fumigatus was the most a-bundant Aspergillus,accounting for 42.5％of the total Aspergillus(1 418/3 340).Among the related infec-tions caused by mold,Aspergillus was the most common in the lower respiratory tract,accounting for 76.8％.Among them,Aspergillus fumigatus accounted for the highest proportion(33.6％).98.6％of the molds infected the ear were Aspergillus,of which Aspergillus niger and Aspergillus terreus were the most common.Skin infections are mainly caused by Sporothrix schenckii,Trichophyton rubrum,Microsporum ca-nis.The results of in vitro drug sensitivity test showed that the four common Aspergillus isolated in this hos-pital were sensitive to voriconazole,and amphotericin B had better antifungal activity against Mucorales in vitro.Conclusion Based on the main epidemiological characteristics of fungal infections in this hospital,it is recommended that special attention be paid to the admission of patients in the respiratory department during the peak infection period in autumn and winter.In the treatment of fungal infections in different regions and on different body parts,attention should be paid to the differences in the distribution of bacterial species.

Objective : To investigate the occupational exposure to blood-borne pathogens among medical workers in a tertiary general hospital in Hangzhou City from 2010 to 2022, so as to provide the evidence for improving occupational protective measures among medical workers. Methods: The registration and follow-up data of occupational exposure to blood-borne pathogens among medical workers from 2010 to 2022 were collected from the blood-borne occupational exposure monitoring system in a tertiary general hospital in Hangzhou City. The population distribution, occurrence, protection and disposal of occupational exposure to blood-borne pathogens were analyzed using a descriptive epidemiological method. Results: A total of 1 230 cases were reported with occupational exposure to blood-borne pathogens among medical workers in the study hospital from 2010 to 2022, with the highest incidence in 2021 (4.67%) and the lowest incidence in 2010 (0.99%). The incidence of occupational exposure to blood-borne pathogens appeared a tendency forwards a rise from 2010 to 2022 (P<0.05). Of all cases with occupational exposure to blood-borne pathogens, there were 934 women (75.93%), 656 nurses (53.33%), and 514 cases with working experiences of one year and shorter (41.79%). Hand was the predominant site of occupational exposure to blood-borne pathogens (92.03%) and ward was the predominant place of exposure (35.37%), while scalp needle was the predominant mode of exposure (32.68%), and removal of needle was the predominant procedure of exposure (32.36%). A total of 1 106 cases were tested for the blood-borne pathogens in the exposure sources, and 448 cases were tested positive for blood-borne pathogens, with a detection rate of 40.51%. Hepatitis B virus, treponema pallidum and human immunodeficiency virus were the three most common blood-borne pathogens, and there were 739 cases (60.08%) with personal protective equipment during exposure. Following the follow-up surveillance for more than 6 months post-exposure, no infections occurred. Conclusions Junior nurses and hand exposure were predominant among medical workers with occupational exposure to blood-borne pathogens in the study hospital from 2010 to 2022, and hepatitis B virus was the predominant blood-borne pathogen. No post-exposure infections occurred.

ObjectiveTo investigate the status of self-management in patients with spinal cord injury and the related factors. MethodsFrom May, 2020 to February, 2021, 255 patients from a spinal cord injury club were enrolled, and investigated with the general information questionnaire, self-management ability scale, Chronic Disease Self-efficacy Scale through internet. Multiple linear stepwise regression was used to explore the related factors. ResultsThe scores of disease symptom management, daily life management, intermittent catheterization behavior management, emotional management and social return were (40.458±9.122), (33.945±6.800), (36.709±8.736) and (25.011±4.932), respectively. The average score for the single question of daily life management was the highest (3.772±0.755), while emotional management and social return was the lowest (3.573±0.705). Duration of intermittent catheterization, family members' attitude, self-efficacy and occupation were the related factors of symptom management (R² = 0.135, F = 7.744, P < 0.001). Self-efficacy, duration of intermittent catheterization, use of hydrophilic coated catheters and complications were the related factors of daily life management (R² = 0.173, F = 13.042, P < 0.001). Self-efficacy, duration of intermittent catheterization, use of hydrophilic coated catheters and medical insurance were the related factors of intermittent catheterization behavior management (R² = 0.141, F = 10.259, P < 0.001). Self-efficacy, duration of intermittent catheterization, complications and frequency of intermittent catheter in the last week were the related factors of emotional management and social regression dimensions (R² = 0.282, F = 19.590, P < 0.001). ConclusionThe self-management of patients with spinal cord injury by clean intermittent catheterization is at medium level. Moreover, it may be affected by many factors. Some of them can be targets of intervention.

Objective:To evaluate the effect of intestinal carbapenem-resistant Enterobacteriaceae (CRE) active screening combined with enhanced intervention in the prevention and control of nosocomial infection in patients admitted to the hematological ward.Methods:Patients who were admitted to the Department of Hematology in a tertiary-care general hospital from March 1, 2017 to December 31, 2019 and underwent chemotherapy or immunosuppressive therapy comprised the intervention group. They were screened for intestinal CRE at least thrice. From December 1, 2016 to February 28, 2017, patients who underwent chemotherapy or immunosuppressive therapy without active intestinal CRE screening in the Department of Hematology formed the control group. Both the patient groups were monitored for CRE infection in real time. The χ2 test was used to compare the changes in the CRE infection rate and mortality in high-risk patients before and after the active screening. Results:During the intervention period, the CRE colonization rate of patients was 16.46% (66/401) ; in terms of disease distribution, the colonization rate of acute leukemia was the highest 23.03% (26/113) . Of the 66 colonized patients, 27 (40.9%) patients were identified as positive for CRE at the first screening, 15 (22.7%) were identified at the time of the second screening, and the remaining 24 (36.4%) were identified at the third or subsequent screening; Carbapenem-resistant Klebsiella pneumoniae (CRPK) strains were dominant among the pathogens, accounting for 54.55% (36/66) . During the active screening period, the CRE infection rate (2.49%) and mortality rate (50.00%) of high-risk patients were significantly lower than those of the controls (11.30% and 69.23%, respectively) . The pathogens of 10 CRE infection patients during the intervention period were exactly the same as the previous active screening pathogens, and the coincidence rate was 100%.Conclusion:The CRE colonization rate was the highest in patients with acute leukemia who were admitted in the hematology wards. CRPK is the main pathogen of CRE colonization, infection, and death. Increasing the frequency of screening can significantly raise the positive rate of screening, Active screening can effectively reduce the incidence and subsequent mortality of CRE in high-risk patients admitted in the hematological wards. High coincidence rate between CRE screening positive pathogens and subsequent CRE infection pathogens. Intestinal CRE screening can serve as an indicator of CRE bloodstream infection in patients with hematological diseases as well as provide information for antibiotics therapy.

Objective:To explore the resilience of nurses against COVID-19 in Xixi Hospital of Hangzhou and to analyze its influencing factors.Methods:From February 4th to 5th 2020, this study investigated 193 nurses against COVID-19 at Xixi Hospital of Hangzhou selected by convenience sampling with the general questionnaire, Connor-Davidson Resilience Scale (CD-RISC) and the General Self-Efficacy Scale (GSES) . Pearson correlation and multiple linear regression were used to analyze the influencing factors of resilience.Results:Among 193 nurses, the total score of resilience was (62.60±13.70) ; the scores of three dimensions, optimism, self-reliance and tenacity were (9.59±2.37) , (21.62±4.68) and (31.40±7.74) respectively. The total score of GSES was (28.33±3.55) . Simple correlation showed that there were statistical differences in the total score of CD-RISC and dimension score of tenacity among nurses with different genders, experience of participating in emergent public health events, self-conscious readiness degree and confidence in fulfilling the task ( P<0.05) . Pearson correlation showed that resilience had a positive correlation with the general self-efficacy with a statistical difference ( r=0.474, P<0.01) . Multiple regression analysis demonstrated the influencing factors of nurses against COVID-19 were the self-conscious readiness degree, confidence in fulfilling the task and the general self-efficacy which totally explained 27.6% of the variance. Conclusions:Nurses against COVID-19 have the low level of the resilience which needs to be improved. We should pay more attention to the high-risk population, and provide a positively and effectively psychological intervention to improve the resilience of nurses against COVID-19.
