RESUMO

Objective: To analyze the risk factors affecting regional lymph node metastasis in salivary gland mucoepidermoid carcinoma (MEC) and to establish a nomogram model for individually predicting lymph node metastasis in salivary gland MEC. Methods: The clinical data of 2 152 patients with salivary gland MEC from 1975 to 2020 were collected from the Surveillance, Epidemiology, and End Results (SEER) database of the National Cancer Institute. The collected data were divided into training cohort (1 506 cases) and validation cohort (646 cases) according to the ratio of 7∶3. Single-factor regression and multi-factor logistic regression were used to screen factors related to local lymph node metastasis in salivary gland MEC, with constructing of a nomogram. Calibration curve, receiver operating characteristic (ROC) curve, area under the ROC curve (AUC) and decision curve analysis were used to evaluate model performance in the validation cohort and the total cohort. Statistical tests were performed using SPSS (26.0) and R (4.3.0) software. Results: Multivariate logistic regression results showed that M stage [OR(95%CI):12.360(3.295-46.365), P=0.014], pathological grade Ⅱ、Ⅲ、Ⅳ[OR(95%CI): 1.956(1.329-2.879), 9.654(6.309-14.772), 9.298(6.072-14.238), P<0.001], T staging T2, T3, T4[OR(95%CI): 1.706(0.932-3.124), 3.021(1.790-5.096), 3.311(1.925-5.695), P<0.001], and gender [OR(95%CI):0.759(0.593-0.972), P=0.029] were independent factors affecting local lymph node metastasis in salivary gland MEC. Through verification in the validation cohort and the total cohort, the AUC values were greater than 0.8, and the calibration curve was close to the perfect reference line, proving that the constructed nomogram model had good specificity and sensitivity for predicting local lymph node metastasis in salivary gland MEC. Conclusion: M stage, pathological grade, T stage, and gender are risk factors for predicting regional lymph node metastasis and the established-nomogram has good predictive performance for local lymph node metastasis in salivary gland MEC.

RESUMO

Extracorporeal carbon dioxide removal (ECCO2R) is a respiratory support technique based on extra-pulmonary gas exchange, which can effectively remove carbon dioxide generated in-vivo, reducing the requirements of respiratory support from mechanical ventilation. With improvements in extracorporeal life support technologies and increasing clinical experience, ECCO2R has potential value in clinical application with acute respiratory distress syndrome (ARDS). This review article discusses the principles of ECCO2R, its relevant indications for ARDS, clinical evidence, existing issues, and future directions, aiming to provide more references for the application in ARDS.

RESUMO

Objective: To investigate the feasibility and safety of distal radial artery approach in emergency percutaneous coronary intervention(PCI) of elderly ST-segment elevation myocardial infarction(STEMI) patients. Methods: This study is a cross-sectional study. Elderly patients with acute myocardial infarction who received emergency PCI at the Third Central Hospital of Tianjin from January 2020 to December 2022 were selected. They were divided into the distal radial artery group and the classic radial artery group based on the puncture location. The success rate, puncture time, surgical success rate, and surgical time of the two groups were observed; The incidence of complications in patients, including radial artery occlusion rate, radial artery spasm rate, local hematoma rate, aneurysm incidence rate were recorded. Results: There were 70 cases in the distal radial artery group, including 33 males (47.1%), aged (65.6±6.7) years old; There were 70 cases in the classic radial artery group, including 35 males (50.0%), aged (66.4±6.9) years old. There was no statistically significant difference in puncture success rate, puncture time, surgical success rate, and surgical time between the distal radial artery group and the classical radial artery group (P>0.05). The incidence of radial artery occlusion in the distal radial artery group was significantly lower than that in the classical radial artery group (1.4% vs. 8.6%, P=0.024). The postoperative compression time in the distal radial artery group was significantly shorter than that in the classical radial artery group ((291.6±10.5) min vs. (343.5±9.8) min, P=0.047). There was no statistically significant difference in the incidence of radial artery spasm, local hematoma, and aneurysm between the two groups (P>0.05). Conclusions: The distal radial artery approach has a lower radial artery occlusion rate, shorter compression time, and better safety. It can be used as a new approach for emergency PCI in elderly patients with STEMI for clinical application.
