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 analyze the real-world effectiveness and safety of tofacitinib in the treatment of alopecia ophiasis, and to compare characteristics of patients with different clinical responses.Methods:A retrospective study was conducted on patients with alopecia ophiasis who visited the Department of Dermatology, China-Japan Friendship Hospital from March 1, 2022, to July 31, 2023. All patients received tofacitinib in combination with topical minoxidil or glucocorticoids, intralesional glucocorticoid injections, oral isotretinoin, antidepressants, antihistamines, traditional Chinese medicine, etc., and were followed up for 36 weeks. The primary outcome was the number of patients achieving complete remission and partial remission at week 36; secondary outcomes included the number of patients achieving a severity of alopecia tool (SALT) score of ≤ 20 points and those with a response rate of ≥ 50% in scalp hair regrowth (SALT50) . Clinical characteristics were compared between patients who achieved and did not achieve a SALT score of ≤ 20 points. Comparisons among groups were performed using the two-independent-sample t test, Mann-Whitney U test, and Fisher's exact test. Results:A total of 21 patients with alopecia ophiasis were collected, and all received oral tofacitinib citrate at a dose of 5 mg twice daily for at least 36 weeks. After a 36-week follow-up, 2 patients (9.5%) achieved complete remission, 16 (76.2%) achieved partial remission, and 3 (14.3%) showed no response. SALT50 was achieved in 12 patients (57.1%) , and 13 (61.9%) had a SALT score of ≤ 20 points. Adverse reactions included mild liver transaminase elevation (1 case) , headache (1 case) , and folliculitis (2 cases) . At week 36, the patients achieving a SALT score of ≤ 20 points exhibited significantly decreased proportions of patients with body hair loss (7/13) and of patients with childhood-onset alopecia ophiasis (7/13) compared with those having a SALT score of > 20 points (both 8/8, both P = 0.046) . However, there were no significant differences between the above two groups in gender, age, body mass index, total disease duration, baseline SALT scores, positivity rates of thyroid antibodies or prevalence of total allergen-specific IgE abnormalities (all P > 0.05) . Conclusion:Combination therapy with tofacitinib showed generally good efficacy and safety in the treatment of alopecia ophiasis, and poorer outcomes were likely to be observed in patients with body hair involvement and childhood-onset alopecia ophiasis.

Objective:To explore the effect of smoking on the sleep quality of military pilots.Methods:A questionnaire survey was conducted among military pilots who underwent a modified physical examination in Air Force Medical Center. The pilots were divided into smoking group and non-smoking group according to whether they smoked or not, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess their sleep quality. The difference in sleep quality was compared between 2 groups.Results:A total of 665 questionnaires were issued, of which 627 were valid, with an effective rate of 94.29%. There were 291 pilots in smoking group and 336 in non-smoking group. The average sleep time of 627 military pilots was (7.58±0.70) h, and the average PSQI score was (2.93±0.09) points. The PSQI score of the smoking group was (3.28±0.14) points, and the PSQI score of the non-smoking group was (2.63±0.10) points, and the difference between 2 groups was significant ( Z=-3.17, P=0.002). Among the factors of the PSQI scale, there were significant differences in sleep onset time, sleep time, sleep efficiency, sleep disorder and daytime dysfunction between the smoking group and the non-smoking group ( Z=-5.85, -2.47, -1.98, -2.18, -1.98, P<0.001,=0.014, 0.049, 0.029, 0.049), and there was no statistically significance in sleep quality and hypnotic drugs intake ( Z=-1.65, -0.94, P=0.098, 0.347). Conclusions:Smoking can affect the sleep quality of military pilots, and it is necessary to actively carry out propaganda and education to persuade pilots away from smoking and maintain physical health.

Objective:To explore the current situation of maternal childbirth readiness and analyze its influencing factors, providing a basis for improving maternal childbirth readiness.Methods:From March to July 2023, convenience sampling was used to select 355 pregnant women who visited Obstetrics Clinic in three Class Ⅲ Grade A hospitals in Chengde City, Hebei Province as participants. Participants were surveyed using the self-designed General Information Questionnaire, Childbirth Readiness Scale, Perceived Social Support Scale, Family APGAR Index, and Childbirth Self-efficacy Inventory 32. LASSO regression and random forest importance ranking were used to select characteristic variables, and multiple linear regression was combined to enhance interpretability, so as to explore the important factors affecting maternal childbirth readiness.Results:The total score of the Childbirth Readiness Scale for 355 pregnant women was (74.41±7.09), and the mean score of each item was (4.13±0.39). The random forest algorithm showed that when the lambda (λ) value was 0.167 7, the error was minimized, and the corresponding number of influencing factors was six. The top six independent variables in importance ranking were perceived social support, childbirth self-efficacy, gestational week, primiparous status, participation in maternity school, and place of residence. Multiple linear regression analysis showed that perceived social support, childbirth self-efficacy, whether primigravida, gestational week, and participation in maternity school were important influencing factors of maternal childbirth readiness ( P<0.05) . Conclusions:The childbirth readiness of pregnant women is above the middle level. Medical and nursing staff can start with factors that affect the childbirth readiness of pregnant women, adopt personalized nursing measures for pregnant women with different characteristics, and encourage family members to provide sufficient family support to improve the readiness of pregnant women for childbirth.

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.
