Article Abstract
Purpose: To analyze the safety and feasibility of computed tomography (CT)-guided thermal ablation of multiple pulmonary nodules combined with intraoperative biopsy.
Methods: The data of 431 patients with 540 lung nodules undergoing CT-guided biopsy or ablation were retrospectively analyzed. Biopsy-only group (A): 107 patients (107 lesions) received CT-guided percutaneous lung biopsy only; Ablation-only group (B): 117 cases (117 lesions) only received CT-guided thermal ablation; Single focal ablation combined with biopsy group (C): 103 patients (103 lesions) received CT-guided thermal ablation combined with intraoperative immediate biopsy; Multifocal ablation combined with biopsy group (D): 104 patients (213 lesions) received CT-guided thermal ablation combined with intraoperative biopsy. The success rate of this technique was calculated, the complications were recorded, and the positive rate of pathological diagnosis of the specimens was evaluated (the tissue specimens could be confirmed as positive by pathological diagnosis).
Results: All 431 patients with pulmonary nodules successfully completed the operation, and the technical success rate was 100% (431/431). In group A, hemoptysis occurred in seven cases after operation, while no hemoptysis was observed in the other groups. Pneumothorax occurred in 8 cases in group A, 14 cases in group B, 11 cases in group C, and 13 cases in group D. Hydrothorax occurred in 4 cases in group A, 7 cases in group B, 5 cases in group C and 9 cases in group D, and there were no significant differences between the groups. The positive rate of pathological diagnosis was 84.1% (90/107) in group A, 81.5% (84/103) in group C, and 82.6% (176/213) in group D, and there was no significant difference among the groups ( > 0.05). A total of 15 cases in group C and 23 cases in group D underwent gene testing and analysis, and the biopsy tissue samples all met quality control standards.
Conclusion: CT-guided thermal ablation of multiple pulmonary nodules combined with intraoperative biopsy does not prolong the length of hospital stay or increase the risk of postoperative complications. It can meet the requirements of clinical, pathological and genetic testing, and is safe and reliable.

Accurate differentiation between persistent vegetative state (PVS) and minimally conscious state and estimation of recovery likelihood in patients in PVS are crucial. This study analyzed electroencephalography (EEG) metrics to investigate their relationship with consciousness improvements in patients in PVS and developed a machine learning prediction model. We retrospectively evaluated 19 patients in PVS, categorizing them into two groups: those with improved consciousness ( = 7) and those without improvement ( = 12).

Objective: To explore the clinical efficacy of internal fixation of locking compression plate and Cannulated Screw in treatment of elderly femoral neck fractures.
Methods: 175 patients with femoral neck fractures admitted to our hospital from January 2022 to December 2022 were enrolled in the study. 93 cases in the control group were treated with Cannulated Screw internal fixation, and 82 cases in the observation group were treated with locking plate internal fixation.
Changing Utilization of Primary Anatomic and Reverse Shoulder Arthroplasty in a Single High-Volume Institution: A Retrospective Cohort Study.

Objective: The incidence of total shoulder arthroplasty (TSA) in the United States continues to climb as an aging yet active population increases demand for the procedure. Due to promising clinical results out of Europe, improvement in prosthesis design, and wider acceptance of reverse total shoulder arthroplasty (rTSA), this study was designed to evaluate how rTSA and anatomical TSA (aTSA) utilization, patient selection, and length of stay have changed at a single institution.
Methods: This was a retrospective cohort study of patients from one hospital system between 2017 and 2023.
