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.

Objective To explore the experience of social isolation among caregivers of stroke patients,and to provide corresponding references for the development of targeted intervention strategies.Methods A descriptive qualitative study was used to select 14 caregivers of hospitalized stroke patients attending the Department of Neurology and Neurosurgery of a tertiary-level hospital in Kunming City from September to November 2023 through purposive sampling method,and the data were analyzed using traditional content analysis.Results A total of 3 themes and 10 sub-themes were extracted,including characterization of social alienation(accumulation of negative emotions,limited social contact,dissolution of self-identity),drivers of social alienation(limitations of disease perception,multiple role conflicts,lack of support resources,constraints of caregiving responsibilities),and coping needs for social alienation(craving for informational support,appeal for emotional support,and expectation of policy support).Conclusion Caregivers of stroke patients are socially alienated due to limited social contact,multiple role conflicts,and lack of support resources,etc.Healthcare professionals should conduct regular assessments,provide targeted education and training,and strengthen multidimensional support in order to help them reintegrate into society and improve the overall quality of life of stroke families.

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 interaction between non-alcoholic fatty liver disease (NAFLD) and overweight/obesity on the risk of mild cognitive impairment (MCI) in elderly individuals.Methods:This cross-sectional study was based on the Hubei Memory and Aging Cohort Study (HMACS). Cluster random sampling was used to select 5 661 elderly individuals aged≥65 years in Wuhan from 2018 to 2023. Standardized neuropsychological assessments and clinical examinations results were collected. The NAFLD was diagnosed by abdominal ultrasound. The logistic regression analysis was used to analyze the association of NAFLD and overweight/obesity with MCI. The impacts of interaction between NAFLD and overweight/obesity on the risk of MCI were analyzed using both multiplicative and additive models.Results:Among the 5 661 elderly individuals included in the analysis, 2 563 were male and 3 098 were female, with a mean age of (72.24±5.51) years. A total of 2 239 participants (39.6%) resided in rural areas, 2 841 (50.2%) were overweight/obesity, 2 390 (42.2%) had NAFLD, and 1 694 (29.9%) were diagnosed with MCI. The risk of MCI in elderly individuals with NAFLD and overweight/obesity was 2.975 times ( OR=2.975, 95% CI: 2.489-3.557, P<0.001) of that in non-overweight/obese individuals without NAFLD. There was a multiplicative interaction between NAFLD and overweight/obesity on MCI ( OR=1.508, 95% CI: 1.169-1.944, P=0.002). NAFLD and overweight/obesity had an additive interaction effect on the risk of MCI, and the relative excess risk of interaction, attributable proportion of interaction and the synergy index was 1.099 (95% CI: 0.630-1.593), 0.369 (95% CI: 0.222-0.487), 2.256 (95% CI: 1.457-3.492), respectively. Conclusion:There is an interaction between NAFLD and overweight/obesity in elderly individuals, and the co-existence of NAFLD and overweight/obesity increases the risk of MCI in this population.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective:To evaluate the efficacy of the flipped classroom combined with 3D body anatomy software in the teaching of ultrasound-guided transversus thoracic muscle plane block.Methods:In this randomized controlled trial, 100 second-year resident physicians from the Department of Anesthesiology and Perioperative Medicine at our hospital, male or female, aged 22-26 yr, who rotated during January 2023 to January 2025, were selected and divided into 2 groups ( n=50 each) using a table of random numbers: experimental group and control group.
