Objective To explore predictive factors of severe community-acquired pneumonia (CAP) complicated with respiratory failure (RF) and to develop and internally validate a clinical prediction model. Methods A retrospective study was conducted on 350 patients with severe CAP admitted to Tianyou Hospital Affiliated to Wuhan University of Science and Technology from September 2022 to December 2024. Patients were randomly divided into a training set (n＝245) and a validation set (n＝105) in a 7∶3 ratio, and further categorized into RF and non-RF groups. LASSO regression was applied to optimize variable selection. Multivariate logistic analysis was used to construct the prediction model, followed by internal validation. Results Univariate regression analysis identified male, hypertension, diabetes, coronary heart disease, age, CURB-65 score, white blood cell count, neutrophil count, C-reactive protein (CRP), serum amyloid A, procalcitonin, and hospital stay as risk factors for RF in severe CAP, while albumin level was a protective factor. LASSO regression selected CURB-65 score, albumin level, and CRP for inclusion in the final model. The area under the receiver operating characteristic curve was 0.903 in the training set and 0.919 in the validation set. Calibration curve analysis demonstrated excellent agreement between predicted and observed probabilities in both sets, and Hosmer-Lemeshow goodness-of-fit tests indicated no significant deviations. Threshold probabilities ranged from 0.01 to 0.99 in both training and validation sets. Conclusions CURB-65 score, albumin level, and CRP are independent predictors of RF in severe CAP. The clinical prediction model based on these factors exhibits strong discrimination, calibration, goodness-of-fit, and clinical utility.

Objective To comprehend the present condition of sustaining within familial pulmonary rehabilitation for COPD patients,alongside exploring the factors that impact this continuity.Methods A convenience sampling method was used to select 392 COPD patients from outpatient clinics of 2 tertiary-level A hospitals and 1 community health service center in Huaihua in Hunan Province from December 2023 to February 2024 as survey respondents.Patients were surveyed using the general information questionnaire,the COPD Assessment Test,the Modified Medical Research Council Dyspnea Scale,the Exercise Benefits/Barriers Scale,and the Brief 2-Way Social Support Scale.Results We sent out 392 questionnaires and collected 362 valid ones,with an effective response rate of 92.47％.The percentage of COPD patients who never performed home pulmonary rehabilitation was 56.08％,and the maintenance time of health behaviors in home pulmonary rehabilitation was 17.40％for 1-3 months,7.18％for 4-6 months,4.70％for 7-12 months,and 14.64％for more than 1 year.The results of multiple linear regression analysis showed that exercise place,pulmonary rehabilitation health education,exercise habits before having COPD,perceived level of exercise behavior,and two-way social support were influential factors affecting the maintenance of health behaviors in pulmonary rehabilitation in the families of COPD patients,which explained 38.5％of the variability.Conclusion Patients with COPD have a low level of maintenance of health behaviors in home pulmonary rehabilitation,and health education on exercise rehabilitation for COPD patients and caregivers should be strengthened to enhance patients'level of exercise perception and ability to utilize social support.

Objective:To explore the antipyretic effect and partial mechanism of the pushing Tianheshui manipulation on lipopolysaccharide(LPS)-induced fever in young New Zealand rabbits. Methods:Thirty 50-day-old New Zealand rabbits were randomly assigned to five groups,including a normal group,a model group,a Tuina(Chinese therapeutic massage)group,a Tuina control group,and a drug group,with 6 rabbits in each group.All groups except for the normal group received LPS injections through the marginal ear vein to induce fever.One hour post-modeling,the Tuina and Tuina control groups received pushing Tianheshui manipulation and pushing manipulation on the medial middle of the hind limbs,respectively,administered every hour for a total of 3 interventions.The drug group was given acetaminophen oral liquid via gavage.Anal temperature was recorded every 30 min for 4.0 h to monitor temperature changes among groups.At 4.0 h post-modeling,hypothalamus samples from each group were analyzed using Western blotting(WB)and real-time quantitative polymerase chain reaction(RT-qPCR)to measure the relative expression levels of α-melanocyte-stimulating hormone(α-MSH),melanocortin 4 receptor(MC4R),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),nuclear factor-κB p65(NF-κB p65),and interleukin(IL)-1β proteins and their mRNAs. Results:Compared to the model group,the Tuina group showed a significant reduction in the anal temperature from 3.5 h to 4.0 h post-modeling(P<0.05).The Tuina control group did not show a significant temperature reduction from 0.5 h to 4.0 h post-modeling(P>0.05).The drug group exhibited a significant temperature reduction from 1.5 h to 4.0 h post-modeling(P<0.05).At 4.0 h post-modeling,compared to the model group,the Tuina group showed significantly increased relative expression of α-MSH and MC4R proteins and mRNAs(P<0.05)and significantly decreased relative expression of cAMP,PKA,NF-κB p65,and IL-1β proteins and mRNAs in the hypothalamus tissue(P<0.05).No significant differences were observed in these parameters in the Tuina control group compared to the model group(P>0.05). Conclusion:Pushing Tianheshui manipulation demonstrated a significant antipyretic effect,potentially linked to point specificity.Its mechanism may involve the α-MSH-mediated cAMP/PKA/NF-κB pathway.

Objective To investigate current situations of emotional labour,career success and psychological resilience among the nurses and to explore the mediating role of psychological resilience between emotional labour and career success,hence to provide a reference in improvement of the sense of career success among the nurses.Methods Convenience sampling was used to select 922 clinical nurses from 15 Gade ⅡA hospitals in Hubei Province between June and July 2021.A general information questionnaire,the emotional labour scale,career success scale,and psychological resilience scale were used in the investigation.Pearson correlation was employed to analyse the correlations between emotional labour,career success and psychological resilience scores.Amos software was used to construct structural equation model to analyse the mediating effect.Results A total of 842 clinical nurses completed the survey.The total scores of career success and mental resilience of clinical nurses were(73.56±15.55)scores and(62.50±17.12)scores,respectively.In emotional labor,the surface acting dimension score was(20.46±5.92)scores.The score of deep acting dimension was(11.05±2.62),and the score of true emotion expression dimension was(11.95±3.48).Perceived career success was positively correlated with psychological resilience(r=0.593,P<0.001)Career success was negatively correlated with surface acting(r=-0.507,P<0.001).Career success was positively correlated with true emotional expression(r=0.481,P<0.001),and was positively correlated with deep acting(r=0.462,P<0.001).Psychological resilience was negatively correlated with surface acting(r=-0.452,P<0.001),positively correlated with true emotion expression(r=0.402,P<0.001),and positively correlated with deep acting(r=0.392,P<0.001).Psychological resilience plays a partial mediating role between the dimensions of emotional labor(surface acting,true emotional expression,deep acting)and career success,and the mediating effect is-0.146,0.108 and 0.112,accounting for 38.02%,32.05%and 37.21%of the total effect,respectively.Conclusion The three mensions of the emotional labor are at middle level and career success of clinical nurses is above the average level,but the psychological resilience is at a low level.In emotional labor,surface acting can directly negatively affect the ca reer success of clinical nurses,real emotion expression and deep acting can directly positively affect the career success of clinical nurses,and indirectly affect the career success of clinical nurses through the mediating effect of psychological resilience.Nursing managers should pay attention to the management of nurses'emotional labor,improve the level of psychological resilience,and then increase their sense of career success.

Objective To explore the impact of the three-level assistance model based on the narrative nursing theory on the mental health status of medical staff.Methods 140 medical staff working in a third class hospital in Xiangyang City were selected as the research object.The three-level assistance model based on narrative nursing theory was used to intervene them from September 2021 to July 2022.The symptom self-assessment scales before and after the intervention were compared.Results Before the intervention,the total score of SCL-90(156.37±32.56)points and the scores of various symptom factors of medical staff were higher;After the intervention,the total score of SCL-90(133.35±43.48)points and the scores of various symptom factors were lower than those before the intervention and the difference was statistically significant(P<0.05).Conclusion The three-level assistance model based on narrative nursing theory can reduce the total score of SCL-90 and the scores of various symptom factors,improve the mental health status and mental health level.

Objective:To investigate the clinical features and prognosis of testicular relapse in pediatric acute lymphoblastic leukemia (ALL).Methods:Clinical data including the age, time from initial diagnosis to recurrence, relapse site, and therapeutic effect of 37 pediatric ALL with testicular relapse and treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences between November 2011 and December 2022 were analyzed retrospectively. Patients were grouped according to different clinical data. Kaplan-Meier analysis was used to evaluate the overall survival (OS) rate and event free survival (EFS) rate for univariate analysis, and Cox proportional-hazards regression model was used to evaluate the influencing factors of OS rate and EFS rate for multivariate analysis.Results:The age at initial diagnosis of 37 pediatric testicular relapse patients was (5±3) years and the time from initial diagnosis to testicular recurrence was (37±15) months. The follow-up time was 43 (22, 56) months. Twenty-three patients (62%) were isolated testis relapse. The 5-year OS rate and EFS rate of the 37 relapsed children were (60±9) % and (50±9) % respectively. Univariate analysis showed that the 2-year EFS rate in the group of patients with time from initial diagnosis to testicular recurrence >28 months was significantly higher than those ≤28 months ((69±10)% vs. (11±11)%, P<0.05), 2-year EFS rate of the isolated testicular relapse group was significantly higher than combined relapse group ((66±11)% vs. (20±13) %, P<0.05), 2-year EFS rate of chimeric antigen receptor T (CAR-T) cell treatment after relapse group was significantly higher than without CAR-T cell treatment after relapse group ((78±10)% vs. (15±10)%, P<0.05). ETV6-RUNX1 was the most common genetic aberration in testicular relapsed ALL (38%, 14/37). The 4-year OS and EFS rate of patients with ETV6-RUNX1 positive were (80±13) % and (64±15) %, respectively. Multivariate analysis identified relapse occurred≤28 months after first diagnosis ( HR=3.09, 95% CI 1.10-8.72), combined relapse ( HR=4.26, 95% CI 1.34-13.52) and CAR-T cell therapy after relapse ( HR=0.15,95% CI 0.05-0.51) were independent prognostic factors for 2-year EFS rate (all P<0.05). Conclusions:The outcome of testicular relapse in pediatric ALL was poor. They mainly occurred 3 years after initial diagnosis. ETV6-RUNX1 is the most common abnormal gene.Patients with ETV6-RUNX1 positive often have a favorable outcome. Early relapse and combined relapse indicate unfavorable prognosis, while CAR-T cell therapy could significantly improve the survival rate of children with testicular recurrence.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective:To test the reliability and validity of the Chinese version of the Demoralization Scale-Ⅱ (DS-Ⅱ) in maintenance hemodialysis (MHD) patients.Methods:This was a cross-sectional study. From October 2021 to February 2022, 989 patients who received MHD in 16 hospitals in Xiangyang City, Hubei Province, were selected by convenience sampling as the study subject. The patients were investigated with the General Information Questionnaire, DS-Ⅱ, Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) . The correlation coefficient and critical ratio were used for project analysis. The reliability of the total scale and sub-scale were tested by Cronbach 's α coefficient, split half reliability coefficient, retest reliability coefficient. The exploratory factor analysis was used to determine item pool dimension and scale structure, and the confirmatory factor analysis was used to test the structural validity of the scale. We tested the correlation among the scores of SAS, SDS and Chinese version of DS-Ⅱ. A total of 989 questionnaires were distributed, and 920 valid questionnaires were recovered, with a valid recovery rate of 93.02% (920/989) . Results:The correlation coefficient among each item score and the total score of the scale was 0.679 to 0.777 ( P<0.05) . The critical ratio of each item in high score group and low score group was 21.637 to 30.719 ( P<0.05) . The total content validity coefficient of the scale was 0.984, and the content validity coefficient of each item was 0.875 to 1.000. Two common factors were extracted after exploratory factor analysis, and the cumulative variance contribution rate was 59.844%. The confirmatory factor analysis showed that the model fitted well, and the correlation coefficients among items and dimensions were 0.687 to 0.803. The total score of DS-Ⅱ and each factor score were positively correlated with scores of SAS and SDS ( P<0.05) . Cronbach 's α coefficient of the total scale was 0.944, and the split half reliability Guttman 's coefficient was 0.884, and the retest reliability coefficient was 0.909. Conclusions:The Chinese version of DS-Ⅱ has good reliability and validity in MHD patients.

BACKGROUND: Currently, the effect of the 2022 nationwide coronavirus disease 2019 (COVID-19) wave on the perioperative prognosis of surgical patients in China is unclear. Thus, we aimed to explore its influence on postoperative morbidity and mortality in surgical patients. METHODS: An ambispective cohort study was conducted at Xijing Hospital, China. We collected 10-day time-series data from December 29 until January 7 for the 2018-2022 period. The primary outcome was major postoperative complications (Clavien-Dindo class III-V). The association between COVID-19 exposure and postoperative prognosis was explored by comparing consecutive 5-year data at the population level and by comparing patients with and without COVID-19 exposure at the patient level. RESULTS: The entire cohort consisted of 3350 patients (age: 48.5 ± 19.2 years), including 1759 females (52.5%). Overall, 961 (28.7%) underwent emergency surgery, and 553 (16.5%) had COVID-19 exposure (from the 2022 cohort). At the population level, major postoperative complications occurred in 5.9% (42/707), 5.7% (53/935), 5.1% (46/901), 9.4% (11/117), and 22.0% (152/690) patients in the 2018-2022 cohorts, respectively. After adjusting for potential confounding factors, the 2022 cohort (80% patients with COVID-19 history) had a significantly higher postoperative major complication risk than did the 2018 cohort (adjusted risk difference [aRD], 14.9% (95% confidence interval [CI], 11.5-18.4%); adjusted odds ratio [aOR], 8.19 (95% CI, 5.24-12.81)). At the patient level, the incidence of major postoperative complications was significantly greater in patients with (24.6%, 136/553) than that in patients without COVID-19 history (6.0% [168/2797]; aRD, 17.8% [95% CI, 13.6-22.1%]; aOR, 7.89 [95% CI, 5.76-10.83]). Secondary outcomes of postoperative pulmonary complications were consistent with primary findings. These findings were verified through sensitivity analyses using time-series data projections and propensity score matching. CONCLUSION: Based on a single-center observation, patients with recent COVID-19 exposure were likely to have a high incidence of major postoperative complications.

ObjectiveTo determine the level of serum 25-hydroxyvitamin D （25（OH）D） and its association with thyroid autoantibodies and thyroid nodules in adult women for health examination in Shanghai. MethodsWe recruited a total of 2 108 healthy women for examination in the hospital. According to the serum 25-hydroxyvitamin D， the women were classified into four groups： 25（OH）D≥30 μg·L^-1 as sufficient group， 20 μg·L^-1≤25（OH）D<30 μg·L^-1 as insufficient group， 10 μg·L^-1≤25（OH）D<20 μg·L^-1 as the deficiency group， and<10 μg·L^-1 as severe deficiency group. The association was determined between the serum 25（OH）D and thyroid autoantibodies and thyroid nodules. ResultsThe prevalence of deficiency in adult women was determined to be 69.31%. Alkaline phosphatase （ALP）， low-density lipoprotein （LDL）， anti-thyroglobulin antibodies （TGAB） and anti-thyroid peroxidase autoantibody （TPOAB） levels significantly differed between the severe deficiency group and sufficient group （each P<0.05）. Moreover， prevalence of thyroid nodules， TGAB， TGAB and/or TPOAB differed significantly across the four groups （each P<0.05）. Logistic regression analysis showed that decrease of serum 25（OH）D was significantly associated with age and increasing prevalence of thyroid nodules， TGAB， TGAB and/or TPOAB. ConclusionVitamin D deficiency remains high in adult women for health examination in Shanghai. Serum 25（OH）D insufficiency or deficiency is associated with age， thyroid autoantibodies and thyroid nodules.
