Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective To explore the potential categories and influencing factors of dietary behavioral adherence trajectories in young and middle-aged patients with type 2 diabetes mellitus.Methods A convenience sampling method was used to investigate 277 young and middle-aged patients with type 2 diabetes mellitus admitted to the Department of Endocrinology of a tertiary A hospital in Huai'an City,China,from September 2022 to March 2023.The baseline data were collected using a general information questionnaire,the Dietary Behavioral Compliance Scale for Patients with Type 2 Diabetes Mellitus,the Diabetes Self-Efficacy Scale,the Diabetes Knowledge Text,the Health Beliefs Questionnaire,and the Family APGAR Index Questionnaire.The baseline information was collected on the patients'behavioral adherence trajectories a day prior to hospital discharge(T0),a week post-discharge(T1),a month post-discharge(T2),and 3 months post-discharge(T3)to assess the level of patients'dietary behavioral adherence,using latent variable growth mixed models to identify trajectory categories,and univariate and multivariate logistic regression to analyze the influences on dietary adherence trajectories.Results A total of 3 trajectories of dietary behavior adherence in young and middle-aged patients with type 2 diabetes mellitus were identified,namely,low adherence-fluctuating group(49.8%),high adherence-slowly regressing group(31.4%),and medium adherence-continuously rising group(18.8%),and the results showed that age,literacy level,self-efficacy,health beliefs,and family caring were the factors influencing potential categories of dietary behavioral adherence for young and middle-aged patients with type 2 diabetes mellitus.Conclusion There is heterogeneity in the adherence trajectories of young and middle-aged patients with type 2 diabetes mellitus,and healthcare professionals can develop targeted interventions according to the influencing factors of the trajectory categories in order to improve their adherence.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

Objective:To assess the prevalence of metabolic syndrome(MS) and its relationship with hyperuricemia(HUA) in perimenopausal women in Anning city, Yunnan province.Methods:This is a cross-sectional survey. In May 2021, a multi-stage stratified sampling method was used to collect demographics and clinical data [ethnicity, living community, height, weight, waist circumference, blood pressure, fasting plasma glucose, triglycerides(TG), serum uric acid, high density lipoprotein-cholesterol(HDL-C), alanine transaminase(ALT), etc] in a total of 6 721 perimenopausal women aged 45-60 years.Results:A total of 6 721 perimenopausal women were included in this study. The prevalences of MS and HUA were 14.05%(95% CI 13.22%-14.88%) and 6.46%(95% CI 5.88%-7.07%), respectively. The average age, HDL-C, urea, direct bilirubin, and albumin levels in the perimenstrual HUA population were lower than those in the non-HUA population while the levels of TG, ALT, heart rate, body mass index(BMI), and creatinine were higher(all P<0.05). The prevalence of HUA in perimenopausal women with ethnic minorities and family history of chronic diseases was higher than that in Han nationality and without family history of chronic diseases. The prevalence of MS in perimenopausal women was increased with the increase of serum uric acid( Z=-15.313 8, P<0.001). Multivariate logistic regression model showed that HUA was positively correlated with MS( OR=1.526, 95% CI 1.192-1.954) after adjusting for covariates such as BMI and ethnicity, and the incidence of MS in perimenopausal women in HUA group was 1.526 folds higher than that in non-hyperuricemia group. Conclusion:HUA is highly positively correlated with MS in perimenopausal women. The management of uric acid level in perimenopausal women should be strengthened.

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 investigate the function and mechanism of CXC chemokine receptor 7 (CXCR7) in neuronal cells of ischemic stroke.Methods:The expression of CXCR7 in human neuroblastoma SH-SY5Y cells was interfered by small interfering RNA (si-RNA) technique. Oxygen-glucose deprivation/reoxygenation (OGD/R) injury model was constructed in SH-SY5Y cells. CXCR7 protein expression and cell cycle were detected by flow cytometry (FCM). The protein expression of CXCR7 and Akt signaling pathway was detected by Western blotting.Results:After 6 hours of OGD/R, the expression of CXCR7 was significantly decreased compared with OGD/R 0 hour (CXCR7/GAPDH: 0.483±0.098 vs. 1.000±0.000 by Western blotting and 0.686±0.0524 vs. 1.000±0.000 by FCM, both P < 0.01), cell cycle arrest in G0/G1 phase (1.190±0.040 vs. 1.000±0.000, P < 0.01). After CXCR7 si-RNA interference with SH-SY5Y cells, OGD/R was constructed again for 6 hours. Compared with negative control group (si-NC group) under the same environment, the expression of CXCR7 and phosphorylated Akt (p-Akt) was significantly decreased (CXCR7/GAPDH: 0.471±0.051 vs. 1.000±0.000, p-Akt/GAPDH: 0.616±0.027 vs. 1.000±0.000, both P < 0.001) and cell cycle arrest in G0/G1 phase (1.105±0.033 vs. 1.000±0.000, P < 0.05). Conclusion:The CXCR7 could regulate the cycle of neuronal cells in ischemic stroke through Akt signaling pathway, which has a protective effect on neuronal cells.

Objective:To explore the influencing factors of frailty in elderly patients with coronary heart disease (CHD), and to compare and analyze the value of different frailty scales in screening elderly patients with coronary heart disease.Methods:Using cross-sectional research methods，elderly patients with coronary heart disease from November 2019 to January 2020 in the Department of Cardiology of a tertiary hospital in Zhenjiang City were selected as the research objects. The frailty status of the patients was evaluated by the frailty index scale, and the patients were divided into frailty group (54 cases) and non-frailty group (149 cases) according to the evaluation results. F-test was used for the comparison between measurement data groups conforming to normal distribution, and χ 2 test or exact probability method was used for the comparison of counting data. Multivariate Logistic regression was used to analyze the main influencing factors of elderly patients with coronary heart disease. The correlation and consistency of clinical frail scale, frail scale and frail index were compared and analyzed were analyzed by Spearman correlation and Kappa test. ROC curve was used to analyze the sensitivity, specificity and the area under the working characteristic curve. Results:The age ((78.96±6.78) years), the percentage of monocytes >10% (31.48% (17/54)), the specific index for coronary heart disease ≥4 points (57.41% (31/54)), Barthel index <100 points (85.19% (46/54)), the mini nutritional assessment scale <24 points (66.67% (36/54)) of the patients in the frail group was higher than these in non-frail group ((73.94±5.89) years old, 12.08%(18/149), 7.38%(11/149), 22.15%(33/149), 14.77%(22/149)), the differences were statistically significant (statistical values were t=5.15, χ 2=10.46, χ 2=60.45, χ 2=66.26, χ 2=52.32; P values were <0.001,0.001,<0.001,<0.001,<0.001,respectively). The results of multivariate Logistic regression analysis showed that the percentage of monocytes >10% ( OR=5.927, 95% CI:1.854-18.947), the mini nutritional assessment scale <24 ( OR=7.026, 95% CI:2.660-18.555),the specific index for coronary heart disease ≥4 points ( OR=3.333, 95% CI:1.889-26.850,) and Barthel index <100 points ( OR=15.649, 95% CI:5.403-45.321) are the main effects of frailty in elderly patients with coronary heart disease factors ( P values were 0.003,<0.001,<0.001, and <0.001, respectively). Taking the frailty index as the gold standard, the sensitivity of the clinical frailty scale and FRAIL scale were 85.19% and 85.19%, respectively, and the specificity was 90.60% and 94.63%, respectively, with no significant difference (χ 2 values were 0.000 and 1.767; all P>0.05). The Kappa of the clinical frailty scale scale was <0.75, while the Kappa of the FRAIL scale was >0.75. The consistency of the frail scale with the gold standard was better than that of the clinical frailty scale scale. Conclusion:The percentage of monocytes, the specific index for coronary heart disease, the mini nutritional assessment scale and Barthel index are the main factors affecting the frailty of elderly patients with coronary heart disease. Taking the frailty index score as the standard, the consistency between the screening results of frail scale and frailty index score is better than that of clinical frailty scale scale, which has clinical application value.

Objective:To evaluate the test-retest reliability of MRI criteria in the 2019 Bosniak classification of cystic renal masses (CRMs) and to analyze the impact of lesions′ property, size and readers′ experience on the test-retest reliability.Methods:From January 2009 to June 2019, 207 patients with 207 CRMs were included in this retrospective study. All of them underwent renal MRI and surgical-pathologic examination. According to Bosniak classification, version 2019, all CRMs were independently classified twice by eight radiologists with different levels of experience. All radiologists were blinded to the pathology of the lesions. By using intraclass correlation coefficient (ICC), test-retest reliability was evaluated for all CRMs and for subgroups with different pathological properties (benign and malignant) and different sizes (≤40 mm and>40 mm). The test-retest reliability of 4 senior readers (≥10 years of experience) and 4 junior readers (<10 years of experience) were evaluated respectively. The comparison of ICC was performed using Z test. Results:The 207 CRMs included 111 benign lesions (83 benign cysts, 28 benign tumors) and 96 malignant tumors. There were 87 lesions with maximum diameter ≤40 mm and 120 with maximum diameter>40 mm. The test-retest reliability (ICC) of each reader for all lesions was 0.776-0.888, the overall ICC was 0.848 (95%CI 0.821-0.872). The ICCs of senior and junior readers were 0.853 (95%CI 0.824-0.880) and 0.843 (95%CI 0.811-0.871) respectively, without significant difference between the two groups ( Z=0.85, P=0.374). The ICC of all readers was 0.827 for benign lesions and 0.654 for malignant lesions, showing significant difference ( Z=2.80, P=0.005). The ICC was 0.770 for lesions ≤40 mm and 0.876 for lesions>40 mm, which was significantly different ( Z=-2.36, P=0.018). For CRM subgroups with different pathological properties and different sizes, there was no significant difference in test-retest reliability between senior and junior readers (all P>0.05). Conclusion:The test-retest reliability of MRI criteria in the 2019 Bosniak classification of CRMs is excellent and unaffected by readers′ experience. The reliabilities are not consistent among CRMs of different pathological properties and different sizes, but all reached the level of good and above.

Objective:To build the three different risk prediction models for peripherally inserted central catheter (PICC) -associated thrombosis based on machine learning algorithm, and compare the performance of the models, so as to provide a basis for evaluating and preventing PICC-associated thrombosis.Methods:The PICC-associated Thrombasis Risk Factor Questionnaire was developed based on the best evidence and expert consultation. From January 2016 to October 2020, convenience sampling was used to select 626 patients with PICC in the Affiliated Hospital of Jiangsu University as the research object to collect clinical data. Based on machine learning algorithms, Support Vector Machine (SVM) , XGBoost and Logistic regression methods were used to construct three different PICC-associated thrombosis risk prediction models, which were evaluated and compared.. Model evaluation indicators included Matthews correlation coefficient ( MCC) , F1 value, area under the receiver operating characteristic curve ( AUC) and Brier score. Results:A total of 30 variables were included, and the predictors included four aspects, namely, demographic data of patients, patient condition, treatment factors, and catheter-related factors. For the model verified on the test set, the Logistic regression prediction model had lower scores than the XGBoost and SVM prediction models in terms of MCC and F1 values. On AUC, the Logistic regression prediction model score was equal to SVM and smaller than XGBoost. On Brier, the Logistic regression prediction model scored higher than the XGBoost and SVM prediction models. Conclusions:The performance of the prediction model based on the machine learning algorithm XGBoost and SVM is superior to the traditional Logistic regression model in terms of sensitivity and accuracy. Thrombotic predictors can help guide medical and nursing staff to identify high-risk patients and reduce the incidence of PICC-associated thrombosis.

Objective:To establish a program for the prevention and management of parastomal hernia in patients with ostomy.Methods:Based on literature analysis and clinical needs, combined with the individual and family self-management theory (IFSMT), a preliminary plan for prevention and management of parastomal hernia was developed with the framework of case management model. Sixteen experts were selected for two rounds of Delphi expert consultations to analyze and screen indicators at all levels to calculate the expert′s positive coefficient, authority coefficient and coordination coefficient to analyze the credibility of expert consultation results.Results:The effective recovery rates of the two rounds of expert letter inquiries were 88.89% and 100.00%, the authoritative coefficients were 0.825 and 0.844, and the two rounds of Kendall′s W values were 0.221 and 0.269, which were statistically significant( P<0.01). The concentration of indicators is high. Finally, a programe for parastomal hernia prevention and management based on the self-management theory of individual and family consisting of 6 first-level indicators,16 second-level indicators and 42 third-level indicators was obtained. Conclusion:The programe for prevention and management of parastomal hernia based on individual and family self-management theory has high reliability and scientificity, and can provide a basis for the study of parastomal hernia prevention and management.
