Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

Objective:To conduct a scoping review to analyse the types, performance, advantages and disadvantages of cognitive function assessment tools for ICU patients, to provide a reference for the evaluation of cognitive function in ICU patients in future.Methods:A scoping review study was conducted, literature on cognitive function assessment tools for ICU patients in 9 domestic and foreign databases including China National Knowledge Infrastructure, Wanfang Database, VIP Database, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase and CINAHL were systematically searched. The search period was from the establishment of the database to May 20, 2024. Literature was independently screened by 2 researchers and relevant information was extracted and summarized.Results:Totally 17 studies were included, with 9 tools for assessing cognitive function in ICU patients, including 6 questionnaires, 1 test battery, 1 assessment software, and 1 telephone interview questionnaire. All of above were generalizable tools, except for the Chinese and English versions of the John-Hopkins Adapted Cognitive Exam as ICU-specific tools. The Mini-Mental State Examination was the most widely used assessment scale.Conclusions:Appropriate assessment tools should be selected according to the specific clinical setting, but there is still a lack of specialized and standardized assessment tools for cognitive dysfunction in ICU patients. In the future, standardized tools which fit our cultural context for evaluating cognitive function in ICU patients should be developed.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective    To summarize the experience of robot-assisted lung basal segmentectomy, and analyze the clinical application value of intersegmental tunneling and pulmonary ligament approach for S9 and/or S10 segmentectomy. Methods    The clinical data of 78 patients who underwent robotic lung basal segmentectomy in our hospital between January 2020 to May 2022 were retrospectively reviewed. There were 32 males and 46 females with a median age of 50 (33-72) years. The patients who underwent S9 and/or S10 segmentectomy were divided into a single-direction group (pulmonary ligament approach, n=19) and a bi-direction group (intersegmental tunneling, n=19) according to different approaches, and the perioperative outcomes between the two groups were compared. Results    All patients successfully completed the operation, without conversion to thoracotomy and lobectomy, serious complications, or perioperative death. The median operation time was 100 (40-185) min, the blood loss was 50 (10-210) mL, and the median number of dissected lymph nodes was 3 (1-14). There were 4 (5.1%) patients with postoperative air leakage, and 4 (5.1%) patients with hydropneumothorax. No patient showed localized atelectasis or lung congestion at 6 months after the operation. Further analysis showed that there was no significant difference in the operation time, blood loss, thoracic drainage time, complications or postoperative hospital stay between the single-direction and bi-direction groups (P>0.05). However, the number of dissected lymph nodes of the bi-direction group was more than that of the single-direction group [6 (1-13) vs. 5 (1-9), P=0.040]. Conclusion    The robotic lung basal segmentectomy for pulmonary nodules is safe and effective. The  perioperative results of robotic S9 and/or S10 complex segmentectomy using intersegmental tunneling and pulmonary ligament approach are similar.

Objective     To compare the perioperative outcomes of atypical segmentectomy between robotic-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) in early-stage non-small cell lung cancer (NSCLC). Methods    The data of patients who underwent minimally invasive anatomic atypical segmentectomy in our hospital from October 2016 to December 2021 were collected. These patients were divided into a RATS group and a VATS group according to the operation method. Propensity score (PS) matching was used to select patients with close clinical baseline characteristics, and the perioperative results of the two groups were compared. Results    A total of 1 048 patients were enrolled, including 320 males and 728 females, with a mean age of 53.51±11.13 years. There were 277 patients in the RATS group and 771 patients in the VATS group. After 1∶1 PS matching, 277 pairs were selected. Both groups were well balanced for age, sex, smoking history, body mass index, Charlson comorbidity index, pulmonary function, tumor size, tumor location, and histological type. All patients were R0 resection, and there were no deaths within 30 days after surgery. The RATS group had shorter operative time [85 (75, 105) min vs. 115 (95, 140) min, P<0.001] and less blood loss [50 (30, 100) mL vs. 60 (50, 100) mL, P=0.001]. There were no statistical differences between the two groups in lymph node resection, conversion to thoracotomy, thoracic drainage time, total amount of thoracic drainage or postoperative complications (P>0.05). Conclusion    Both RATS and VATS atypical segment-ectomies are safe and feasible for early-stage NSCLC. RATS can effectively shorten the operative time, and reduce blood loss.

Objective    To explore the clinical efficacy of thoracoscopy-assisted modified Nuss procedure for pectus excavatum (PE) in children. Methods    The clinical data of patients with PE who underwent thoracoscopy-assisted modified Nuss procedure from October 2013 to October 2020 in Daping Hospital were retrospectively analyzed. Results    A total of 86 patients were collected, including 79 males and 7 females with a mean age of 14.03±3.36 years. The operations were performed successfully in all patients without intraoperative cardiac vascular injury or perioperative death. The mean operation time was 87.30±33.45 min, bleeding volume was 19.94±14.60 mL, and the postoperative hospitalization stay time was 6.89±2.59 d. Early postoperative complications included 2 patients of pneumothorax, 2 patients of wound fat liquefaction and infection, 2 patients of bar flipping and displacement. One patient had bar displacement 1 year after the surgery. The total complication rate was 8.14%. All patients were followed up for 3-42 months. The bars were taken out about 36 months after the surgery. According to the evaluation criteria of orthopedic effect, 68 (79.07%) patients were excellent, 10 (11.63%) patients were good, 5 (5.81%) patients were moderate and 3 (3.49%) patients were poor. Conclusion    Minimally invasive and individualized shaping via the Nuss procedure for PE children is safe and convenient, with satisfied effect. It is worthy of popularization in the clinic.

Objective:To explore the feasibility and application value of case-based learning (CBL) combined with clinical pathway in thoracic surgery practice teaching.Methods:A total of 30 clinical undergraduate students who practiced from January 2018 to August 2018 were selected and randomly divided into the traditional group and the research group. The traditional group used traditional teaching mode, while the research group adopted the CBL combined with clinical pathway teaching. The scores of theoretical examination and practice skills assessment and the case analysis ability of the two groups were compared at the time of department. In addition, the evaluation of the teaching effect of the two groups of teachers and students was observed through anonymous questionnaires. SPSS 21.0 was used for t-test and Chi-square test. Results:The scores of the students in the research group were better than those in the traditional group, including score of theoretical examination [(88.20±4.02) vs. (80.76±4.62), P<0.001], score of practice skills assessment [(90.80±2.16) vs. (84.80±3.07), P<0.001] and case analysis ability [(89.80±3.34) vs. (81.86±4.31), P<0.001]. The differences were statistically significant. At the same time, the questionnaire showed that the research group was superior to the traditional group in improving students' learning interest, clinical skills, case analysis ability, clinical communication ability, theoretical knowledge understanding and clinical thinking ability, with a statistically significant difference ( P<0.05). While the two groups had no statistically significant difference in students' satisfaction with teachers ( P=0.083). Conclusion:The CBL method combined with clinical pathway teaching method can improve the teaching effect of thoracic surgery practice, which is worth popularizing.

Objective:To explore the value of a radiomics nomogram based on T 1WI for prediction of the relapse of osteosarcoma after surgery within 1 year from multicenter data. Methods:The imaging and clinical data of 107 patients with pathologica1ly confirmed osteosarcoma who received neoadjuvant chemotherapy before surgery from 6 hospitals from January 2009 to October 2017 were retrospectively analyzed. A training cohort consisted of 75 patients from firstly enrolled 4 hospitals and an independent validation cohort of 32 patients from other 2 hospitals. Pretreatment T 1WI was used to extract radiomics features. Least absolute shrinkage and selection operator (LASSO) regression was applied to reduce the dimension and then the radiomics signature was constructed to predict the relapse of osteosarcoma after surgery within 1 year in training cohort. Independent clinical risk factors were screened using one-way logistic regression, and then a radiomics nomogram incorporated the radiomics signature and MRI characteristics was developed by multivariate logistic regression. The predictive nomogram was evaluated using receiver operating characteristic (ROC) curve in the training cohort, and validated in the independent validation cohort. The calibration curve was used to evaluate the agreement between prediction and actual observation and the decision curve was used to demonstrate the clinical usefulness. Results:Based on T 1WI from multicenter institutions, the radiomics signature was built using 2 valuable selected features that were significantly associated with relapse within 1 year. Two selected features included 1 gray-level co-occurrence matrices (GLCM) feature (L_G_1.0_GLCM_homogeneity1, LASSO coefficient 3.122) and 1 gray-level run length matrix (GLRLM) feature (GLRLM_RP, LASSO coefficient -2.474). The prediction nomogram including radiomics signature and MRI characteristics (joint invasion and perivascular involvement) showed good discrimination with the area under the ROC curve of 0.884 and 0.821 in the training and validation cohorts, respectively. The calibration curve showed that the nomogram achieved good agreement between prediction and actual observation. Decision curve analysis demonstrated that the radiomics nomogram was clinically useful when the threshold probability was greater than 21%. Conclusion:The radiomics nomogram based on T 1WI can be used as a non-invasive quantitative tool to predict relapse of osteosarcoma within 1 year before treatment, which provides support for clinical decision-making in osteosarcoma.
