Background: Hemorrhage, particularly from non-compressible torso hemorrhage (NCTH) in the abdominopelvic region, is a leading cause of preventable trauma deaths. Resuscitative endovascular balloon occlusion of the aorta (REBOA), designed for aortic occlusion, has emerged as a tool for temporary hemorrhage control in recent years. However, attaining optimal REBOA placement in diverse demographic groups, such as Asian populations, may pose challenges owing to unique anatomical and physiological differences.
Materials and methods: This retrospective study analyzed trauma patients who underwent torso computed tomography (CT) at tertiary hospitals in Taiwan from January 2014 to January 2017. The OsiriX software was used to measure the endovascular lengths in the CT images.
Results: Among the 223 patients, the median vascular lengths and body measurements were higher in males. The optimal fixed insertion length was identified as 47.5 cm for zone 1 with 99.43% accuracy and 25.5 cm with 82.1% accuracy for zone 3. The landmark-guided method showed 100% accuracy for zone 1 when using the mid-sternum and 94.6% for zone 3 with the umbilicus as the guide with the distance between the umbilicus, xiphoid process, and pubic ramus. External validation confirmed the accuracy of the landmark-guided method.
Conclusions: For zone 1 occlusions, a range of 44-48 cm insertion length cross-referenced with the mid-sternal landmark is recommended. For zone 3 occlusions, using the umbilicus as a guide with the distance between the umbilicus, xiphoid process, and pubic ramus provided the highest accuracy.

Background: Extracorporeal shockwave therapy (ESWT) is the primary treatment for calcific tendinitis of the shoulders, but what are the effects of clinical, sonographic, and molecular markers following ESWT in treating calcific tendinitis of the shoulder?
Methods: Twenty-eight patients were categorized into radiodense and radiolucent subgroups. In addition, clinical assessments included the visual analogue scale (VAS), Constant-Murley (CM) score, American Shoulder and Elbow Surgeon (ASES) score, sonographic evaluation, and serum enzyme-linked immunosorbent assay (ELISA). The participants completed a one-year follow-up. All data were collected before and after treatment.
Results: After one year of follow-up, all patients showed notable improvement in VAS, CM, and ASES scores, with no significant clinical variations among the subgroups. However, the radiolucent group showed significant complete resorption and size reduction at the final follow-up. Sonographic evaluation revealed improved tissue perfusion and reduced calcification from 3 to 12 months in all patients, including those in the radiolucent group, but complete resorption of calcific deposits did not occur. The percentage of tissue perfusion was improved at 1 and 3 months after ESWT. There were no significant differences in the levels of the molecular markers interleukin-1 beta (IL-1 β) or IL-33, but the level of insulin-like growth factor 1 (IGF-1) was notably increased at 1 and 3 months post-ESWT. The BMP7 level was increased at 3 months and was then decreased significantly at 6 and 12 months.
Conclusion: ESWT improved symptoms, reduced calcification, enhanced tissue perfusion, and promoted angiogenesis and BMP7 activity. In particular, it benefited radiolucent type patients with better calcification resorption. Partial resorption led to improvements in transparency, and a second ESWT session at 3 months was recommended for optimal results.

Background: Primary aldosteronism (PA) is now recognized as the most prevalent form of secondary hypertension globally, contributing significantly to cardiovascular morbidity and mortality. This umbrella review aims to systematically compare cardiovascular outcomes and all-cause mortality in PA patients undergoing adrenalectomy versus mineralocorticoid receptor antagonist (MRA) treatment, aiming to inform optimal management strategies.
Method: Following PRISMA guidelines, Supplemental Digital Content 1, http://links.lww.com/JS9/D386, Supplemental Digital Content 2, http://links.lww.com/JS9/D387, a comprehensive search strategy was employed across multiple databases. Meta-analyses focusing on cardiovascular outcomes or all-cause mortality, comparing adrenalectomy and MRAs treatment in PA patients, were included. Studies were independently screened and assessed for quality using AMSTAR 2, Supplemental Digital Content 3, http://links.lww.com/JS9/D388 and GRADE checklists.
Results: A total of 8 studies met the inclusion criteria. Adrenalectomy showed potential benefits over MRAs in reducing the risk of arrhythmias (OR=2.17; 95% CI: 1.25-3.76) and major adverse cardiovascular events (OR=1.81; 95% CI: 1.33-2.46). Patients treated with MRAs exhibited a higher risk of cardiovascular events (OR=1.23; 95% CI: 1.05-1.44), hypertension (OR=3.22; 95% CI: 1.15-8.97), and all-cause mortality (OR=3.03; 95% CI: 1.36-6.70) compared to adrenalectomy.
Conclusion: Adrenalectomy appears to offer favorable outcomes compared to MRAs treatment in PA patients, particularly in reducing the risk of major adverse cardiovascular events and all-cause mortality. These findings suggest the importance of considering surgical intervention as a primary treatment modality for PA.
背景:原发性醛固酮增多症(PA)目前被认为是全球最普遍的继发性高血压,对心血管疾病的发病率和死亡率有重大影响。本综述旨在系统比较接受肾上腺切除术与矿皮质激素受体拮抗剂(MRA)治疗的 PA 患者的心血管预后和全因死亡率,旨在为最佳管理策略提供参考:按照 PRISMA 指南(补充数字内容 1,http://links.lww.com/JS9/D386)和补充数字内容 2(http://links.lww.com/JS9/D387),在多个数据库中采用了全面的检索策略。纳入了以心血管预后或全因死亡率为重点、比较 PA 患者肾上腺切除术和 MRAs 治疗的 Meta 分析。采用 AMSTAR 2、Supplemental Digital Content 3、http://links.lww.com/JS9/D388 和 GRADE 检查表对研究进行独立筛选和质量评估:结果:共有 8 项研究符合纳入标准。肾上腺切除术在降低心律失常风险(OR=2.17;95% CI:1.25-3.76)和主要不良心血管事件(OR=1.81;95% CI:1.33-2.46)方面比 MRAs 有潜在优势。与肾上腺切除术相比,接受MRA治疗的患者发生心血管事件(OR=1.23;95% CI:1.05-1.44)、高血压(OR=3.22;95% CI:1.15-8.97)和全因死亡率(OR=3.03;95% CI:1.36-6.70)的风险更高:结论:与 MRAs 治疗相比,肾上腺切除术似乎能为 PA 患者带来更好的治疗效果,尤其是在降低主要不良心血管事件和全因死亡率风险方面。这些研究结果表明,将外科干预作为 PA 的主要治疗方式具有重要意义。

Background: The survey aimed to elucidate the complete range of national practices, including all technical and non-technical aspects, as well as surgical stratification and maturation, of the use of intraoperative neuromonitoring (IONM) during thyroid surgery in China.
Materials and methods: Six national questionnaires, developed by the Chinese Neural Monitoring Study Group (CNMSG) between 2015 and 2023, were used to collect and analyze data regarding the clinical application, education, and scientific research related to IONM in Chinese medical institutions.
Results: Among the surveyed hospitals, 45% reported an average annual surgical volume exceeding 3,000 cases, with 82.5% performing more than 80% of the surgeries for malignant thyroid tumors. Additionally, 97.5% of the hospitals reported a<3% incidence of postoperative hoarseness with IONM. Statistical analysis from 2011 to 2015 found that the incidence of postoperative hoarseness decreased by 30% in 2013 compared with 2011, when the technology was introduced. Preoperative and postoperative laryngoscopies were routinely performed by 82.5% and 15% of the hospitals, respectively. For 65% of the hospitals, the publication of the Chinese edition of neuromonitoring guidelines in 2013 prompted the utilization of IONM technology. An average annual number of IONM applications exceeding 500 cases (18.5% the average volume) was reported by 80% of the hospitals, while 62.5% reported a cumulative number of applications greater than 5,000 cases (47.1% the average cumulative volume). Regarding technical parameters, 75% of the hospitals reported an intraoperative V1 amplitude of >500 µV, and 70% reported an intraoperative loss of signal (LOS) rate of<3%. 92.5% of the surveyed hospitals believed that IONM could help identify dissociated nerves, and 95% of the surveyed hospitals believed that IONM could reduce nerve damage. However, 72.5% of the respondents thought that cost was the main limitation. Furthermore, 67.5% of the hospitals reported that half of their thyroid surgical team members were trained in IONM, with 17.5% reporting that all team members were trained. Areas for reinforced training included IONM research methods and directions (72.5%), and analysis and treatment of abnormal EMG signals (72.5%). Research projects related to IONM were conducted by 42.5% of the hospitals, while 52.5% had published papers on neuromonitoring.
Conclusions: IONM was independently and incrementally associated with the annual surgical volume. This survey emphasized the importance of national collaboration and/or a registry for the uptake, consolidation, and development of CNMSG consensus.

Background: Loss of chromosome 9p is an important biomarker in the malignant transformation of oral leukoplakia (OLK) to head and neck squamous cell carcinoma (HNSCC), and is associated with the prognosis of HNSCC patients. However, various challenges have prevented 9p loss from being assessed in clinical practice. The objective of this study was to develop a pathomics-based artificial intelligence (AI) model for the rapid and cost-effective prediction of 9p loss (9PLP).
Materials and methods: 333 OLK cases were retrospectively collected with hematoxylin and eosin (H&E)-stained whole slide images and genomic alteration data from multicenter cohorts to develop the genomic alteration prediction AI model. They were divided into a training dataset (n=217), a validation dataset (n=93), and an external testing dataset (n=23). The latest Transformer method and XGBoost algorithm were combined to develop the 9PLP model. The AI model was further applied and validated in two multicenter HNSCC datasets (n=42, n=365, respectively). Moreover, the combination of 9PLP with clinicopathological parameters was used to develop a nomogram model for assessing HNSCC patient prognosis.
Results: 9PLP could predict chromosome 9p loss rapidly and effectively using both OLK and HNSCC images, with the area under the curve achieving 0.890 and 0.825, respectively. Furthermore, the predictive model showed high accuracy in HNSCC patient prognosis assessment (the area under the curve was 0.739 for 1-year prediction, 0.705 for 3-year prediction, and 0.691 for 5-year prediction).
Conclusion: To the best of our knowledge, this study developed the first genomic alteration prediction deep learning model in OLK and HNSCC. This novel AI model could predict 9p loss and assess patient prognosis by identifying pathomics features in H&E-stained images with good performance. In the future, the 9PLP model may potentially contribute to better clinical management of OLK and HNSCC.

Objective: The present study aims to explore the roles of infusion time, administration sequence and interval of immunochemotherapy (IO) in predicting overall survival (OS) in patients with locally advanced ESCC.
Methods: This multi-center retrospective study enrolled advanced ESCC who received IO between Nov 2019 and Nov 2021. Patients were divided into groups according to the three classifiers (IO infusion time, administration sequence, and infusion interval), and were further analyzed for the roles of these classifiers in predicting the prognosis of the ESCC patients.
Results: A total of 183 eligible patients with locally advanced ESCC were included in this study. Patients who received ≥ 75% of immunotherapy drug infusions after 12:00 h had better OS compared to those who received < 75% of immunotherapy drug infusions after 12:00 h in the 1:1 propensity score matching analysis (HRadjusted: 0.38, 95% CI: 0.17-0.82; P = 0.013). Cox proportional hazards regression revealed that ESCC patients with shorter infusion interval (< 3.3 h) had better OS (HRadjusted: 0.34, 95% CI: 0.15-0.76; P = 0.008).
Conclusion: For patients with ESCC, the OS is significantly better when immunotherapy was administered after 12:00 h. A shorter infusion interval (< 3.3 hours) on the same-day immunochemotherapy could lead to a better prognosis.

Background: Parkinson's disease (PD) is linked with metabolic risk factors including body mass index (BMI), fasting blood glucose (FBG), cholesterol levels, and triglycerides (TG). The extent to which these factors affect motor symptoms, depression, and sleep problems in PD, as well as their role in determining the success of deep brain stimulation (DBS) therapy, is yet to be fully understood.
Methods: This study delved into the effects of metabolic risk factors like BMI, FBG, cholesterol, and TG on the outcomes of DBS in treating PD-related depression and sleep disturbances, across both mouse models and human subjects.
Results: DBS showcased noticeable betterment in depression and sleep perturbations in both PD-afflicted mice and patients. High-sugar-high-fat diet aggravates MPTP-induced depression and sleep disorders in mice. PD-afflicted individuals presenting with depressive and sleep disorders demonstrated elevated metrics of BMI, FBG, blood cholesterol, and TG. Remarkably, these metrics bore considerable adverse influences on the efficiency of DBS in ameliorating depression and sleep issues, yet spared motor symptoms. The favorable impacts of DBS persisted for approximately 6 years, post which a significant decline was noted. Importantly, our translational evidence from both murine controls and patient cohorts indicated that antihyperglycemic and antihyperlipidemic therapies bolstered the efficacy of DBS in mitigating PD-related depression and sleep disturbances, without impinging upon motor functions in patients.
Conclusion: In summary, this research emphasizes that DBS is a powerful treatment option for depression and sleep issues in PD, with its success influenced by metabolic risk factors. It further suggests that incorporating treatments for high blood sugar and cholesterol can enhance the efficacy of DBS in treating depression and sleep disturbances in PD, without impacting motor symptoms, highlighting the importance of metabolic risk management in PD patients receiving DBS.

Background: Surgical resection is a curative therapy for early-stage hepatocellular carcinoma (HCC) patients meeting the Milan criteria as well as a widely used therapy in intermediate-stage HCC. However, intermediate-stage HCC encompasses a wide spectrum of disease and there is a lack of good predictive models for the long-term clinical outcome of HCC patients currently. Here, we adopt Mazzaferro's Metroticket 2.0 to create a robust survival prediction model for intermediate-stage HCC patients undergoing surgical resection. Our algorithm considers age, AFP levels, ALBI score, and nodule size/number to generate survival estimates in an accessible graph format. Importantly, our model surpasses the American Joint Committee on Cancer staging model and was validated with independent US patient data.
Methods: We conducted a retrospective analysis of OS and RFS in early- and intermediate-stage HCC patients treated with liver resection, including a training cohort in Singapore and a validation cohort in North Carolina, USA.
Results: We recorded 278 deaths (35.0%) and 428 patients (53.9%) in the first 5-years after surgical resection; higher ALBI score, higher lnAFP, more advanced age and higher tumour burden index were identified as significant parameters. The overall predictive capability of our model, with the inclusion of AFP, is reflected with a UNO's C-statistic of 0.655, which is 1.11 times better than the 0.5895 C-statistic of the 8th AJCC TNM Staging model.
Conclusions: Our modified Metroticket model allows for more granular and better-informed prognostication. This will help surgeons and patients make accurate comparisons between the clinical outcomes of surgical resection and other non-surgical treatments.

Introduction: Sacrococcygeal teratoma (SCT) is a rare congenital tumour. The risk of malignancy and recurrence are not well defined. Previous studies are small and report differing conclusions about the timing of surgery and the duration of follow-up. We studied the risk of malignant transformation and SCT recurrence after surgery to address these gaps.
Methods: This was a global retrospective cohort study. Data of consecutive SCT patients was obtained from 145 institutes in 62 countries. Malignant transformation, defined as malignancy at initial resection, malignant recurrence or death due to malignancy, and its risk factors were analysed.
Results: Of the 3612 included patients, 3407 entered analysis. Risk of malignant transformation of the initial tumour, was 3.3%, 5.1%, 10.1%, and 32.9% at age three months, six months, one year, and two years, respectively. After six years, the censored risk of malignancy (64%) did not further increase. Recurrent SCT was diagnosed in 349 (10·2%) children with 126 (36·1%) malignant recurrences. Risk factors for recurrence were Altman type II (odds ratio (OR): 1·6, 95% confidence interval (CI): 1·2-2·3), Altman type III (OR: 1·6, 95% CI: 1·2-2·3), initial immature histology (OR: 1·9, 95% CI: 1·4-2·6), and initial malignant histology (OR: 4·0, 95% CI: 2·9-5·4).
Conclusion: The risk of malignancy at initial resection in SCT increases with age reaching a plateau at six years of age. Recurrence after resection occurred in 10% of patients and 36% of these were malignant at that time. Altman type II or type III, and immature or malignant histology were associated with recurrence.

Background: Polydatin (POL), a natural stilbenoid, has multiple pharmacological activities. However, its effect on osteoporotic bone defect has not yet been examined. This study was designed to explore the unknown role of POL on osteoporotic bone repair.
Methods: The effect of POL on osteogenesis and angiogenesis were investigated firstly. Then a series of angiogenesis-related assays were carried out to explore the relationship between osteogenesis and angiogenesis of POL, and the underlying mechanism was further explored. Whereafter, ovariectomy-induced osteoporosis rats with bone defect were treated with POL or placebo, the imageological and histological examinations were conducted to assess the effect of POL on osteoporotic bone repair.
Results: The moderate concentrations (1 μM and 10 μM) of POL enhanced osteogenesis of bone marrow mesenchymal stem cells (BMSCs) and elevated the expression of angiogenic-specific markers. Further research found that POL induced human umbilical vein endothelial cells migration and tube formation through the osteogenesis-angiogenesis coupling of BMSCs, and the POL-induced osteogenesis-angiogenesis coupling was reversed after co-cultured with LY294002, Mechanistically, this was conducted via activating PI3K/AKT/GSK-3β/β-catenin pathway. After that, using osteoporotic bone defect rat model, we observed that POL facilitated osteoporotic bone repair through enhancing osteogenesis and CD31hiEMCNhi type H-positive vessels formation via the PI3K/AKT/GSK-3β/β-catenin pathway.
Conclusion: The data above indicated that POL could accelerate osteoporotic bone repair by inducing the osteogenesis-angiogenesis coupling of BMSCs via the PI3K/AKT/GSK-3β/β-catenin pathway, which provided new insight and strategy for osteoporotic bone repair.
背景:多靛酚(POL)是一种天然类芪类化合物,具有多种药理活性。然而,它对骨质疏松性骨缺损的影响尚未得到研究。本研究旨在探索 POL 对骨质疏松性骨修复的未知作用:方法:首先研究 POL 对骨生成和血管生成的影响。方法:首先研究了 POL 对骨生成和血管生成的影响,然后进行了一系列血管生成相关试验,以探讨 POL 的骨生成和血管生成之间的关系,并进一步探索其潜在机制。之后,用 POL 或安慰剂治疗卵巢切除诱导的骨质疏松症大鼠的骨缺损,并进行影像学和组织学检查,以评估 POL 对骨质疏松症骨修复的影响:结果:中等浓度(1 μM和10 μM)的POL增强了骨髓间充质干细胞(BMSCs)的成骨能力,并提高了血管生成特异性标志物的表达。进一步研究发现,POL通过BMSCs的成骨-血管生成耦合诱导人脐静脉内皮细胞迁移和管形成,而与LY294002共培养后,POL诱导的成骨-血管生成耦合被逆转,其机制是通过激活PI3K/AKT/GSK-3β/β-catenin通路进行的。随后,我们利用骨质疏松性骨缺损大鼠模型观察到,POL通过PI3K/AKT/GSK-3β/β-catenin途径促进骨生成和CD31hiEMCNhi H型阳性血管形成,从而促进骨质疏松性骨修复:上述数据表明,POL可通过PI3K/AKT/GSK-3β/β-catenin通路诱导BMSCs的成骨-血管生成耦合,从而加速骨质疏松症骨修复,为骨质疏松症骨修复提供了新的思路和策略。
