Objective:
This study investigates the potential of radiomics to predict postoperative progression of ossification of the posterior longitudinal ligament (OPLL) after posterior cervical spine surgery.
Methods:
This retrospective study included 473 patients diagnosed with OPLL at Peking University Third Hospital between October 2006 and September 2022. Patients underwent posterior spinal surgery and had at least 2 computed tomography (CT) examinations spaced at least 1 year apart. OPLL progression was defined as an annual growth rate exceeding 7.5%. Radiomic features were extracted from preoperative CT images of the OPLL lesions, followed by feature selection using correlation coefficient analysis and least absolute shrinkage and selection operator, and dimensionality reduction using principal component analysis. Univariable analysis identified significant clinical variables for constructing the clinical model. Logistic regression models, including the Rad-score model, clinical model, and combined model, were developed to predict OPLL progression.
Results:
Of the 473 patients, 191 (40.4%) experienced OPLL progression. On the testing set, the combined model, which incorporated the Rad-score and clinical variables (area under the receiver operating characteristic curve [AUC] = 0.751), outperformed both the radiomics-only model (AUC = 0.693) and the clinical model (AUC = 0.620). Calibration curves demonstrated good agreement between predicted probabilities and observed outcomes, and decision curve analysis confirmed the clinical utility of the combined model. SHAP (SHapley Additive exPlanations) analysis indicated that the Rad-score and age were key contributors to the model’s predictions, enhancing clinical interpretability.
Conclusion
Radiomics, combined with clinical variables, provides a valuable predictive tool for assessing the risk of postoperative progression in cervical OPLL, supporting more personalized treatment strategies. Prospective, multicenter validation is needed to confirm the utility of the model in broader clinical settings.

This study aimed to localize the workplace readiness questionnaire (WRQ) and validate its applicability for assessing readiness for implementation of evidence-based practices (EBP) in primary care settings in China. The localization of the instrument will provide a practical instrument for assessing organizational readiness for change (ORC). The WRQ was translateed into Chinese version using the modified Brislin translation model, and its cross-cultural validity, content validity, and generalizability were evaluated by the Delphi method, and the expert feedback was evaluated using the item-level content validity index (I-CVI), scale-level content validity index (S-CVI), and corrected Kappa value. The index weights were evaluated by the analytic hierarchical process (AHP). The target users of the scale were invited to quantitatively evaluate its item importance score (IIS), and the surface validity was evaluated by combining the qualitative feedback from their cognitive interviews. To clarify the purpose of the scale, we revised its name to the Organizational Readiness of Implementing Evidence-Based Practices (ORIEBP) Scale. The ORIEBP scale contained five dimensions, which were Change Context, Change Valence, Information Evaluation, Change Commitment, Change Efficiency, and 32 items. After two rounds of the Delphi method to refine the construction of three dimensions and expressions of 11 items, the I-CVI were from 0.73 to 1.00, the Kappa value were from 0.70 to 1.00, and the S-CVI was over 0.92. All evaluation matrices of the hierarchical analysis method met the requirement of consistency ratio (CR < 0.1), and the weights of five dimensions were 0.2083, 0.2022, 0.1907, 0.2193, and 0.1795, in sequence. Nine out of eleven experts identified that items were applicable to other readiness assessment scenarios. The IIS scores for the five dimensions and 32 items were ranged from 2.93 to 3.54, and 2.71 to 3.42, presenting good face validity. The cognitive interview results showed that professional expressions were complex to understand. This study validated the ORIEBP scale and has good content validity and generalizability. The scale can be further improved by expanding its scope of use and validating its structure validity and reliability in different settings.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective:To investigate the relationship between retinoblastoma binding protein 1 (RB1) gene deletion and the prognosis of multiple myeloma (MM) patients, and the possible effect of renal insufficiency on it.Methods:A retrospective cohort study was conducted. The clinical data and follow-up information of MM patients who were treated in the Second Affiliated Hospital of Xuzhou Medical University and the Affiliated Hospital of Xuzhou Medical University from December 2020 to November 2023 were collected. According to the presence of RB1 gene deletion in bone marrow samples detected by fluorescence in situ hybridization (FISH), the patients were divided into the RB1 gene deletion group and the RB1 gene non-deletion group, and the clinicopathological characteristics and hematological index levels were compared between the two groups. Renal insufficiency was determined by renal function assessment indicator serum creatinine (Scr) >177 μmol/L. The Spearman test was used to analyze the relationship between the number of RB1 gene deletion positive cells and levels of Scr, hemoglobin and serum calcium in MM patients. The Kaplan-Meier method was used to analyze progression-free survival (PFS), and the Cox proportional hazards model was used to determine the influencing factors of PFS in all MM patients and RB1 gene deletion and non-deletion MM patients.Results:A total of 75 MM patients were enrolled, of whom 24 (32.0%) had RB1 gene deletion. There were no significant differences in gender, age ≥65 years old, bone destruction and lactate dehydrogenase level between the RB1 gene deletion and non-deletion groups (all P > 0.05). There were significant differences in the distributions of patients in each stage of MM International Staging System (ISS) and revised International Staging System (R-ISS) between the two groups, as well as in hemoglobin, serum calcium, Scr, β 2-microglobulin, serum albumin levels, and the proportion of bone marrow plasma cells (all P < 0.05). The number of RB1 gene deletion positive cells was positively correlated with Scr level ( r = 0.863, P = 0.016), but not with hemoglobin and serum calcium levels (both P > 0.05). The PFS of the RB1 gene non-deletion group was better than that of the RB1 gene deletion group (1-year PFS rate: 83.5% vs. 71.7%, 2-year PFS rate: 56.3% vs. 26.3%), and the difference was statistically significant ( P = 0.012). PFS in the non-renal insufficiency group was better than that in the renal insufficiency group (1-year PFS rate: 85.6% vs. 61.9%, 2-year PFS rate: 58.0% vs. 13.5%), and the difference was statistically significant ( P = 0.001). The PFS of patients without renal insufficiency in both the RB1 gene deletion and non-deletion groups was better than that in patients with renal insufficiency, and the differences were statistically significant (both P < 0.05). Multivariate Cox regression analysis showed that ISS stage Ⅲ was an independent risk factor for poor PFS in MM patients (stage Ⅲ vs. stage Ⅰ, HR = 11.317, 95% CI: 1.220-104.979, P = 0.033). Multivariate Cox regression analysis in RB1 gene deletion and non-deletion groups showed that ISS stage Ⅲ (stage Ⅲ vs. stageⅠ, HR = 4.166, 95% CI: 1.419-12.225, P = 0.009), R-ISS stage Ⅲ (stage Ⅲ vs. stage Ⅰ, HR = 3.800, 95% CI: 1.005-14.367, P = 0.049), serum calcium > 2.52 mmol/L (> 2.52 mmol/L vs. ≤2.52 mmol/L, HR = 2.398, 95% CI: 1.037-5.546, P = 0.041) and renal insufficiency (yes vs. no, HR = 2.363, 95% CI: 1.021-5.472, P = 0.045) were independent risk factors for poor PFS in RB1 gene non-deletion MM patients, and serum calcium >2.52 mmol/L (>2.52 mmol/L vs. ≤ 2.52 mmol/L, HR = 3.673, 95% CI: 1.160-11.627, P = 0.027) and renal insufficiency (yes vs. no, HR = 3.985, 95% CI: 1.220-13.016, P = 0.022) were independent risk factors for poor PFS in RB1 gene deletion MM patients. Conclusions:The PFS of MM patients with RB1 gene deletion is worse than that of patients without RB1 gene deletion, RB1 gene deletion may be related to renal insufficiency in MM patients, and the prognosis of MM patients with RB1 gene deletion and renal insufficiency may be worse.

The success of implementation research is closely tied to the institution's pre-implementation readiness. This study aims to explore the organizational readiness for change (ORC) and its influencing factors on primary healthcare settings in the implementation of the "Shared Medical Appointment for Diabetes (SMART) in China: design of an optimization trial" and to enhance ORC and provide insights to support the effective implementation of the program. Qualitative interviews and quantitative surveys were conducted to evaluate the ORC level and its influencing factors in 12 institutions implementing the SMART program. The Scale for Assessing the Institution's Readiness to Implement Evidence-Based Practices was utilized to measure ORC levels. Qualitative interviews were conducted among change implementers to gather information regarding the status of influencing factors. Thematic analysis was applied to extract factors from the interview data, and an assessment questionnaire was developed to measure the perceived impact of these factors. A fuzzy-set qualitative comparative analysis (fsQCA) method was employed to identify the influencing factors of ORC and pathways leading to high-level ORC. Seventy implementers from 12 institutions, encompassing administrators, clinicians, and health managers, participated in the interviews and surveys. The median and interquartile of the ORC scores were 105.20 (101.23, 107.33). The fsQCA indicated that a clear understanding of specific tasks and responsibilities, the active engagement of key participants, sufficient preliminary preparation, and the use of audits and feedback mechanisms were critical pathways to a high-level ORC. Conversely, institutions lacking key participants, preliminary preparation, or marginal influence demonstrated a low-level ORC. Before implementing innovation, Coherence and Cognitive Participation were identified as critical factors in influencing ORC. Strong leadership from key participants played pivotal role in enhancing readiness for change and was essential for improving implementation fidelity and overall program success.
