All patients were followed up for 90 days after surgery. The primary endpoint was a composite of dialysis dependence or death at 90 days postoperatively. Patients were divided into a successful renal replacement therapy (RRT) group and a failed RRT group according to whether the endpoint occurred. The clinical data were compared between the two groups. A logistic regression model was used to identify independent risk factors for 90-day RRT failure in AKI patients treated with CRRT after surgery, and the area under the receiver operating characteristic (ROC) curve was calculated to evaluate the predictive performance of the model. <b>Results:</b> A total of 113 patients aged (57.7±12.3) years were enrolled, including 55 males and 58 females. There were 56 patients in the successful RRT group and 57 in the failed RRT group, respectively. Compared with the successful RRT group, patients in the failed RRT group had a higher preoperative prevalence of diabetes mellitus [29.8% (17/57) vs 3.6% (2/56)], lower intraoperative transfused red blood cell volume [(474±188) ml vs (559±195) ml] and platelet units [(1.2±0.6) U vs (1.5±0.7) U], higher serum creatinine at discharge [(230±167) μmol/L vs (129±80) μmol/L], and a larger proportion of dialysis dependence at discharge [80.7% (46/57) vs 39.3% (22/56)] (all <i>P</i><0.05).

Based on the coronal alignment at the final postoperative follow-up, patients were categorized into a coronal balance (CB) group and a CIB group (defined as coronal vertical axis&gt;3 cm). A total of 26 preoperative and intraoperative variables were considered as candidate predictors. Feature selection was performed using three machine learning algorithms, including least absolute shrinkage and selection operator (LASSO) regression, recursive feature elimination (RFE), and Boruta algorithm, and the intersection of the selected features was used as the final input variables. The dataset was randomly divided into a training set and a test set at a 7∶3 ratio using stratified sampling. Five machine learning algorithms, including logistic regression, random forest, extreme gradient boosting (XGBoost), light gradient boosting machine (LightGBM), and multilayer perceptron, were employed to construct predictive models for postoperative CIB. Model performance was evaluated using six metrics: area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The SHapley Additive exPlanations (SHAP) method was used to assess the contribution and importance of each predictor. &lt;b&gt;Results:&lt;/b&gt; A total of 168 patients aged (64.6±8.0) years were included in the study, with 49 males and 119 females.

In addition, the CIB group exhibited a significantly greater correction ratio between the two curves (1.3±0.6 vs 0.8±0.5, &lt;i&gt;P&lt;/i&gt;&lt;0.001), a larger preoperative lumbosacral Cobb angle (22.3°±5.8° vs 18.4°±6.4°, &lt;i&gt;P&lt;/i&gt;&lt;0.001), and greater preoperative coronal displacement [(3.3±1.0) cm vs (2.5±1.4) cm, &lt;i&gt;P&lt;/i&gt;&lt;0.001].

At the final follow-up, osteotomy-site bony fusion was achieved in all 19 patients in the navigation group and in 17 patients in the conventional group, with no significant difference in osteotomy fusion rate between the two groups (19/19 vs 17/18, &lt;i&gt;P&lt;/i&gt;=0.486). At 2 weeks postoperatively and at the final follow-up, GK, LL, SVA, PT, and SS have all improved in both groups compared with the preoperative values (all &lt;i&gt;P&lt;/i&gt;&lt;0.001), and the improvements in these radiographic parameters were superior in the navigation group (all &lt;i&gt;P&lt;&lt;/i&gt;0.05).

The two groups of patients were compared in terms of clinical efficacy [including Visual Analogue Scale (VAS) of pain, Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), and Odom's criteria], operative time, intraoperative blood loss, early complications (intraoperative adjacent organ injury, hematoma formation), postoperative cervical range of motion (ROM), incidence of heterotopic ossification (HO), and adjacent segment degeneration (ASD). &lt;b&gt;Results:&lt;/b&gt; A total of 68 patients were enrolled, including 36 males and 32 females, with a mean age of (48.2±2.8) years. Among them, 33 patients received the Prestige LP disc, and 35 received the 3D-printed disc. The mean follow-up duration was (34.6±2.0) months in the Prestige LP group and (32.8±3.0) months in the 3D-printed group.

Forty middle-aged and elderly patients with acute-phase HZ who attended the Department of Dermatology at Xuanwu Hospital, Capital Medical University, from June 2024 to June 2025 were enrolled and randomly assigned in a 1∶1 ratio using a random number table to receive either taVNS (<i>n</i>=20) or sham stimulation (<i>n</i>=20) for 5 consecutive days. Both groups received antiviral therapy and on-demand rescue analgesia. Pain, anxiety/depression, and sleep quality were evaluated using the Visual Analog Scale (VAS), the 4-item Patient Health Questionnaire (PHQ-4), and the Insomnia Severity Index (ISI), respectively. The primary outcome was the incidence of subacute pain at 30 days post-rash onset. Secondary outcomes included cumulative analgesic consumption at 1 and 2 weeks after treatment, the changes from baseline (Δ values) in PHQ-4 and ISI scores at 2 weeks, and the incidence of postherpetic neuralgia (PHN) at 90 days post-rash onset. <b>Results:</b> In the taVNS group, 7 patients (35%) were female, with a mean age of (64.1±9.7) years; in the sham group, 10 patients (50%) were female, with a mean age of (61.5±8.5) years.
