Purpose: This study aimed to assess the predictive value of preoperative albumin-globulin ratio (AGR) for systemic inflammatory response syndrome (SIRS) after percutaneous nephrolithotomy (PCNL).
Methods: Patients who underwent PCNL in Guizhou Provincial People's hospital between August 2017 and July 2019 were enrolled and retrospectively reviewed. The primary clinical outcome of the current study was the development of SIRS within 48h after PCNL. Univariable and multivariable logistic regression analyses were conducted to verify the predictive value of AGR for post-PCNL SIRS. In addition, receiver operating characteristic (ROC) curves were generated to compare the discriminatory ability of AGR with other inflammatory biomarkers.
Results: 354 patients who underwent PCNL were enrolled and 66 patients (18.64%) developed postoperative SIRS. None of the patients suffered postoperative sepsis in our study. Multivariate analysis demonstrated that female sex (odds ratio [OR]=2.939, 95% odds ratio [OR]: 1.368-6.315, p = 0.006), CRP (OR = 1.008, 95% CI: 1.003-1.012, p = 0.001), and AGR (OR = 0.048, 95% CI: 0.010-0.239, p < 0.001) were all independent predictors for SIRS after PCNL. The optimal cut-off value of AGR for predicting postoperative SIRS was 1.145. In addition, AGR had a higher area under the curve (0.844) with sensitivity of 83.3% and specificity of 88.9% than C-reactive protein (0.808).
Conclusion: Preoperative AGR is a potential predictor for SIRS development after PCNL.

Purpose: This study aimed to investigate whether combining the analysis of different magnetic resonance imaging (MRI) signs enhances the diagnostic accuracy of lateral meniscus posterior root tears (LMPRTs) in patients with anterior cruciate ligament (ACL) injuries. We hypothesised that analysing the cleft, ghost and truncated triangle signs and lateral meniscus extrusion (LME) measurement together would improve the preoperative MRI-based diagnosis of LMPRTs.
Methods: This retrospective study used prospectively collected registry data from two academic centres, including patients undergoing primary or revision ACL reconstruction (ACLR) and LMPRT repair.
External validation of a multivariable prediction model for positive resection margins in breast-conserving surgery.

Objectives: Positive resection margins after breast-conserving surgery (BCS) most often demands a repeat surgery. To preoperatively identify patients at risk of positive margins, a multivariable model has been developed that predicts positive margins after BCS with a high accuracy. This study aimed to externally validate this prediction model to explore its generalizability and assess if additional preoperatively available variables can further improve its predictive accuracy.

Purpose: To develop and validate a prostate-specific membrane antigen (PSMA) PET/CT based multimodal deep learning model for predicting pathological lymph node invasion (LNI) in prostate cancer (PCa) patients identified as candidates for extended pelvic lymph node dissection (ePLND) by preoperative nomograms.
Methods: [Ga]Ga-PSMA-617 PET/CT scan of 116 eligible PCa patients (82 in the training cohort and 34 in the test cohort) who underwent radical prostatectomy with ePLND were analyzed in our study. The Med3D deep learning network was utilized to extract discriminative features from the entire prostate volume of interest on the PET/CT images.

To develop and validate a predictive model for assessing the risk of early postoperative high intraocular pressure (HIOP) following posterior chamber intraocular lens implantation. The clinical data of patients who underwent posterior chamber intraocular lens implantation at the Second Affiliated Hospital of Zhejiang University School of Medicine between May 2023 and April 2024 were retrospectively reviewed. Patients were divided into a modeling group and a validation group with a 7∶3 ratio using computerized random allocation.
