Objective:To adapt and validate the Chinese version of the Supervisory Relationship Questionnaire(SRQ)and evaluate its psychometric properties among supervisees.Methods:Item analysis,exploratory factor anal-ysis(EFA)and confirmatory factor analysis(CFA)were conducted on data from 888 supervisees recruited via on-line platform.Test-retest reliability over a four-week interval was examined in a randomly selected subset of 70 su-pervisees.An additional sample of 367 supervisees completed the Supervisory Relationship Scale(SRS)to evaluate criterion validity.Results:The revised SRQ contained 65 items and 6 factors.Both exploratory factor analysis and confirmatory factor analysis supported six-factor structure(safe base,structure,commitment,reflective education,role model and formative feedback),explaining 66.52％of the variance,with factor loadings of the items ranging from 0.58 to 0.83.The revised SRQ had six factors with good fit indices(x2/df=1.31,GFI=0.81,NFI=0.87,CFI=0.97,TLI=0.90,IFI=0.91,RMSEA=0.03,SRMR=0.05).The scores of the revised SRQ were positively correlated with the scores of SRS(ICC=0.96,P＜0.01).The Cronbach α coefficient of the revised SRQ was 0.97,and the test-retest reliability coefficient(ICC)was 0.74.Conclusion:The SRQ-C demonstrates sound psy-chometric properties,including structural validity,criterion-related validity,internal consistency,and temporal stabil-ity.It is a reliable and valid instrument for assessing supervisory relationships from the supervisee perspective.

Objective:To describe the prevalence of perinatal death in Tongzhou District of Beijing,and to estimate the association between maternal periconceptional supplementation of folic acid or multiple micronutrients containing folic acid and perinatal mortality rate.Methods:A retrospective cohort study was conducted based on the maternal and child care system in Tongzhou District of Beijing.The subjects were 94 490 perinatal who were born during January 2013 to December 2018.The information on perina-tal outcomes and maternal periconceptional supplementation of folic acid or multiple micronutrients contai-ning folic acid were collected.The Poisson log-linear model was used to estimate the association between maternal periconceptional folic acid or multiple micronutrients supplementation and perinatal mortality rate.Results:The overall perinatal mortality rate was 2.71‰.The perinatal mortality rates for maternal nutrients supplementation containing folic acid and no supplementation during periconceptional period were 2.63‰ and 3.43‰,respectively,and the difference in rates was not statistically significant[crude risk ratio(cRR)=0.77,95％CI:0.54-1.14].After adjusting for potential confounding factors in-cluding ethnicity,age,education level,occupation,household registration,parity,numbers of fetuses,gestational age,pregnant with assisted reproductive technology,delivery year and pre-pregnancy body mass index,the rates remained not statistically significant[adjusted risk ratio(aRR)=0.93,95％CI:0.77-1.13].The perinatal mortality rates were 2.23‰ and 2.99‰ for pure folic acid and multi-nutrients supplements containing folic acid,respectively,and the difference in rates was statistically sig-nificant(cRR=1.34,95％CI:1.02-1.76).The rates difference remained statistically significant after adjusting for potential confounders(aRR=1.31,95％CI:1.06-1.62).Additionally,the peri-natal mortality rates differences among the non-supplementation group and the supplementation group with variate timing of initiation(pre-conception or post-conception)or frequency of supplementation(low-frequency or high-frequency)were not statistically significant,regardless of adjusting for confounders.Conclusion:The overall perinatal mortality rate was lower than the national average level in Tongzhou District of Beijing.Maternal periconceptional supplementation of pure folic acid or micronutrients contai-ning folic acid had no impact on perinatal mortality.The association between maternal periconceptional supplementation of multiple micronutrients containing folic acid and perinatal mortality rate need further research.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Objective:To investigate the clinical data, drug resistance and treatment prognosis of Cryptococcus neoformans isolated from patients with acquired immunodeficiency syndrome(AIDS) in a hospital in Shanghai. Methods:The clinical data of AIDS patients with Cryptococcus neoformans infection in Shanghai Public Health Clinical Center from January 2014 to December 2023, and the drug sensitivity to 5 antifungal drugs in vitro, treatment and prognosis were retrospectively analyzed. Results:From January 2014 to December 2023, there were 295 AIDS patients with Cryptococcus neoformans infection in our hospital, with 255 males and 40 females. CD4 + T lymphocyte counts ≤100 cells/μl were detected in 251 patients. A total of 384 strains of Cryptococcus neoformans were isolated from the 295 patients, with the highest detection rate in cerebrospinal fluid samples (65.9%, 253/384), followed by blood samples (29.4%, 113/384). The sensitivity of 384 strains of Cryptococcus neoformans to 5-fluorocytosine was the highest (98.5%, 379/384), followed by fluconazole (95.6%, 367/384) and amphotericin B (95.3%, 366/384). After treatment against cryptococcal infection, 252 patients (86.0%, 252/293) were discharged and 20 patients (6.8%, 20/293) died. The other 2 cases were not treated for cryptococcal infection. Conclusions:As Cryptococcus neoformans is an important pathogen of AIDS patients, clinicians should actively carry out laboratory examination of Cryptococcus and rational drug use according to the results of drug sensitivity test, while alert to the occurrence of drug resistance.

Objective:To investigate the significance of urinary 8-oxo-7, 8-dihydroguanosine(8-oxoGuo)in assessing the short-term prognosis of sepsis in frail elderly patients.Methods:We conducted a cross-sectional study involving 62 frail elderly patients diagnosed with sepsis who were admitted to the Emergency Intensive Care Unit(EICU)at Beijing Hospital between March 2021 and March 2022.Based on their 28-day prognosis, the patients were categorized into two groups: those who died and those who survived.Upon admission, we collected urine samples and clinical data from both groups.We employed isotope dilution high-performance liquid chromatography-mass spectrometry to measure the levels of the RNA oxidation marker 8-oxoGuo in the urine.Results:A total of 62 frail elderly patients[aged(85.1±6.3)years]diagnosed with sepsis were included in the study, comprising 36 patients in the 28-day mortality group and 26 patients in the survival group.Univariate analysis revealed that the survival group had significantly lower body temperature, blood calcitonin(PCT)levels, sequential organ failure assessment(SOFA)scores, and urinary 8-oxoGuo levels compared to the mortality group.Additionally, the survival group exhibited a higher mean arterial pressure(MAP)than the mortality group, with all differences reaching statistical significance(all P<0.05).Spearman correlation analysis indicated that urinary 8-oxoGuo levels were positively correlated with both PCT and SOFA scores in frail elderly sepsis patients( r=0.426, 0.768, both P<0.05).Furthermore, logistic regression analysis identified urinary 8-oxoGuo and SOFA as independent risk factors for 28-day mortality in this population( OR=1.936, 1.427; P=0.006, 0.002).The area under the receiver operating characteristic curve(AUC)for urinary 8-oxoGuo and SOFA in predicting the 28-day prognosis of frail elderly sepsis patients was 0.761 and 0.741, respectively, both demonstrating statistical significance(both P<0.001). Conclusions:Our findings suggest that urinary 8-oxoGuo possesses strong predictive value for the short-term prognosis of sepsis in this vulnerable population.

Objective:To investigate the incidence of common complications following vaginal delivery and analyze their influencing factors among women of reproductive age.Methods:This prospective cohort study consecutively enrolled women who delivered vaginally at two campuses of the Obstetrics and Gynecology Hospital of Fudan University between February and July 2023. Participants were categorized into groups according to complication occurrence: those with obstetric laceration versus those without, postpartum hemorrhage versus non-hemorrhage, and retained placenta/membranes without hemorrhage vs. non-retention. Data were collected using a self-developed questionnaire on risk factors for vaginal delivery complications. Group comparisons of demographics, obstetric history, intrapartum assessments, and delivery outcomes were performed using Chi-square test (or Fisher's exact test), independent samples t-test, and Mann-Whitney U test. Multivariate logistic regression identified risk factors for the three complication types. Results:Among 1 966 vaginal deliveries, the overall complication rate was 8.1% (159/1 966), with obstetric lacerations representing the most frequent complication at 4.6% (91/1 966), followed by postpartum hemorrhage at 2.7% (53/1 966) and retained placenta/membranes without hemorrhage at 1.4% (27/1 966). Multivariate logistic regression analysis identified distinct sets of independent risk factors for each complication. For obstetric lacerations, adequate gestational weight gain was associated with a reduced risk ( OR=0.547, 95% CI: 0.332-0.900, P=0.018), while precipitous labor ( OR=2.633, 95% CI: 1.321-5.248, P=0.006), shoulder dystocia ( OR=2.495, 95% CI: 1.093-5.691, P=0.030), poor maternal cooperation ( OR=1.887, 95% CI: 1.061-3.359, P=0.031), and specific perineal conditions—particularly reduced skin folds ( OR=2.341, 95% CI: 1.247-4.395, P=0.008) and tight/thick/edematous skin ( OR=2.511, 95% CI: 1.248-5.054, P=0.010)—emerged as significant risk factors. Regarding postpartum hemorrhage, conception through assisted reproductive technology ( OR=3.286, 95% CI: 1.189-9.076, P=0.022), presence of obstetric comorbidities ( OR=2.460, 95% CI: 1.070-5.656, P=0.034), elevated D-dimer levels ( OR=1.157, 95% CI: 1.049-1.277, P=0.004), reduced fibrinogen ( OR=0.521, 95% CI: 0.319-0.851, P=0.009), weak uterine contractions ( OR=20.175, 95% CI: 10.352-39.321, P<0.001), abnormal placentation ( OR=2.434, 95% CI: 1.167-5.078, P=0.018), and absence of early skin-to-skin contact ( OR=0.141, 95% CI: 0.067-0.295, P<0.001) were independently associated with increased risk. For retained placenta/membranes without hemorrhage, prolonged thrombin time ( OR=0.117, 95% CI: 0.034-0.318, P<0.001) and abnormal placentation ( OR=51.843, 95% CI: 14.988-179.324, P<0.001) were identified as primary risk factors. Conclusions:While the overall incidence of complications following vaginal delivery among women of reproductive age is relatively low, high-risk groups warrant particular attention. Precipitous labor, shoulder dystocia, poor maternal cooperation, and unfavorable perineal conditions increase laceration risk. Assisted conception, obstetric comorbidities, elevated D-dimer levels, uterine atony, and placental abnormalities elevate hemorrhage risk. Furthermore, placental abnormalities are strongly associated with retained placenta/membranes without hemorrhage.

Objective:To analyze and clarify the conceptual connotation of health behaviors in traditional Chinese medicine (TCM) .Methods:A three-phase hybrid concept analysis method was used. In the theoretical phase, a systematic literature search was conducted in China National Knowledge Infrastructure, Wanfang Data, VIP, China Biology Medicine disc, PubMed, Web of Science, ProQuest, and EBSCO, covering publications up to April 30, 2024. In the fieldwork study, using the purposive sampling method, 8 community residents, 2 family members of residents, and 2 community workers were selected from Wuhan, Yichang, Neijiang, Zigong, Taiyuan, and Dongguan for semi-structured interviews from December 2023 to April 2024. In the analytical, data were compared and integrated.Results:TCM health behaviors are defined as multidimensional and multi-stage actions guided by TCM theories and techniques, aimed at preventing, maintaining, or promoting physical, mental, social, and moral well-being of oneself and others. A total of 8 core attributes were identified: acupoint-based health preservation, diet and herbal maintenance, daily routine regulation, exercise and qigong practice, emotional cultivation, simple lifestyle adjustments, utilization of TCM health resources, and participation in TCM health-related decision-making. Antecedents involve individual, social, environmental, and TCM-specific factors, while consequences include self-health promotion, support of others' well-being, and the dissemination of TCM culture.Conclusions:This study clarified the conceptual structure of TCM health behaviors. The findings can inform the development of localized assessment tools and intervention strategies, thereby supporting clinical nursing practice.
