Correlation analysis between preoperative systemic immune inflammation index and prognosis of patients after radical gastric cancer surgery: based on propensity score matching method.

BACKGROUND: To explore the correlation between the preoperative systemic immune inflammation index (SII) and the prognosis of patients with gastric carcinoma (GC). METHODS: The clinical data of 771 GC patients surgically treated in the Department of Gastrointestinal Surgery, Qinghai University Affiliated Hospital from June 2010 to June 2015 were retrospectively analyzed, and their preoperative SII was calculated. The optimal cut-off value of preoperative SII was determined using the receiver operating characteristic (ROC) curve, the confounding factors between the two groups were eliminated using the propensity score matching (PSM) method, and the correlation between preoperative SII and clinicopathological characteristics was assessed by chi-square test. Moreover, the overall survival was calculated using Kaplan-Meier method, the survival curve was plotted, and log-rank test was performed for the significance analysis between the curves. Univariate and multivariate analyses were also conducted using the Cox proportional hazards model. RESULTS: It was determined by the ROC curve that the optimal cut-off value of preoperative SII was 489.52, based on which 771 GC patients were divided into high SII (H-SII) group and low SII (L-SII) group, followed by PSM in the two groups. The results of Kaplan-Meier analysis showed that before and after PSM, the postoperative 1-, 3-, and 5-year survival rates in L-SII group were superior to those in H-SII group, and the overall survival rate had a statistically significant difference between the two groups (P < 0.05). Before PSM, preoperative SII [hazard ratio (HR) = 2.707, 95% confidence interval (CI) 2.074-3.533, P < 0.001] was an independent risk factor for the prognosis of GC patients. After 1:1 PSM, preoperative SII (HR = 2.669, 95%CI 1.881-3.788, P < 0.001) was still an independent risk factor for the prognosis of GC patients. CONCLUSIONS: Preoperative SII is an independent risk factor for the prognosis of GC patients. The increase in preoperative SII in peripheral blood indicates a worse prognosis.

Concomitant use of peripheral veno-venous extracorporeal membrane oxygenation (VV-ECMO) and central veno-arterial ECMO during lung transplantation for coronavirus disease 2019 patients / 中华危重病急救医学

Objective:To summarize the strategy of using extracorporeal membrane oxygenation (ECMO) support during lung transplantation from 2 coronavirus disease 2019 (COVID-19) with end-stage respiratory failure.Methods:Two COVID-19 with end-stage respiratory failure patients were admitted to Nanjing Medical University Affiliated Wuxi People's Hospital in March 2020. As the homoeostasis and vital signs could not be maintained in balance by conventional treatments, lung transplantations were performed. Here, detail information about combined application of peripheral veno-venous ECMO (VV-ECMO) and central veno-arterial ECMO (CVA-ECMO) during the operation will be discussed.Results:Case 1: 59 years old, 172 cm height, 72 kg weight, who received mechanical ventilation for 22 days, tracheotomy tube for 17 days, and VV-ECMO support for 7 days. Case 2: 72 years old, 178 cm height, 71 kg weight, who received mechanical ventilation for 19 days, tracheotomy tube for 17 days, and VV-ECMO support for 18 days. As both of them have severe COVID-19-associated respiratory failure, and the recovery was determined to be unlikely, lung transplantations were performed. Severe pulmonary arterial hypertension (PAH) and cardiac insufficiency were found during the operation. Based on preoperative VV-ECMO, CVA-ECMO was added. The concomitant use of peripheral VV-ECMO and CVA-ECMO offered satisfied intraoperative oxygenation and cardiopulmonary status, the operations run smoothly, and the CVA-ECMO was successfully removed, no ECMO-related complications occurred.Conclusion:The combined use of VV-ECMO and CVA-ECMO is an optimal strategy in the end-stage ARDS patients with severe PAH and cardiac insufficiency, which can offer benefits on respiratory and cardiac functions simultaneously, and ensure surgery safety.

Risk factors analysis for 1-year postoperative survival of patients with benign end-stage lung diseases after lung transplantation / 中华危重病急救医学

Objective:To investigate the main postoperative complications, causes of death and the risk factors for survival in patient with benign end-stage lung diseases within 1 year after lung transplantation.Methods:A retrospective analysis was conducted to collect the clinical data of 200 patients with benign end-stage lung disease who underwent lung transplantation admitted to Wuxi People's Hospital Affiliated to Nanjing Medical University from May 2017 to October 2018. The main postoperative complications, survival and causes of death within 1 year after operation were analyzed. The Kaplan-Meier method was used to plot survival curves, and the Log-Rank test was used to compare the influence of factors, including recipient's gender, use of marginal donor lung, primary disease, preoperative combination of moderate to severe pulmonary hypertension (PAH), intraoperative extracorporeal membrane oxygenation (ECMO) support, surgical methods, intraoperative massive blood loss, postoperative complications [infection, primary graft dysfunction (PGD), acute rejection], on 1-year survival in patients who underwent lung transplantation. The multivariate Cox proportional hazards regression model was used to evaluate the risk factors of death within 1 year after lung transplantation.Results:Two hundred patients underwent successful lung transplantation. The major postoperative complications within 1 year after transplantation included infection in 131 patients, PGD in 20 patients, acute rejection in 57 patients, anastomotic complication in 26 patients and others (new onset diabetes, osteoporosis, etc.) in 53 patients. The 3-month, 6-month, and 1-year postoperative cumulative survival rates were 81.5%, 80.0% and 77.5%, respectively. Forty-five patients died during 1 year after operation, among whom 14 died of infection, 7 died of PGD, 8 died of acute rejection, 4 died of anastomotic complication, 3 died of cardio-cerebrovascular accident, 3 died of multiple organ failure, 2 died of respiratory failure and 4 died of other causes (traffic accident, etc.). The Kaplan-Meier survival analysis showed that recipient's gender, idiopathic pulmonary fibrosis (IPF) as the primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, postoperative complications (infection, PGD, acute rejection) were influencing factors for postoperative 1-year survival rate. The multivariate Cox regression model showed that male was the protective factor [hazard ratio ( HR) = 0.481, 95% confidence interval (95% CI) was 0.244-0.947, P = 0.034], IPF as the primary disease ( HR = 2.667, 95% CI was 1.222-5.848, P = 0.014), intraoperative use of ECMO support ( HR = 1.538, 95% CI was 0.787-3.012, P = 0.028), massive blood loss during surgery ( HR = 2.026, 95% CI was 0.976-4.205, P = 0.045) and postoperative infection ( HR = 3.138, 95% CI was 1.294-7.608, P = 0.011), PGD ( HR = 1.604, 95% CI was 0.464-5.539, P = 0.004), and acute rejection ( HR = 1.897, 95% CI was 0.791-4.552, P = 0.015) were the independent risk factors for death within 1 year after transplantation. Conclusions:One-year survival rates after lung transplantation are affected by recipient's gender, primary disease, preoperative combination of moderate and severe PAH, intraoperative ECMO support, intraoperative massive blood loss, and postoperative complications (infection, PGD, acute rejection). The male is the protective factor, while IPF as the primary disease, intraoperative ECMO support, massive blood loss during surgery and postoperative complications (infection, PGD, acute rejection) are independent risk factors for death within 1 year after lung transplantation.

Value of preoperative pulmonary artery diastolic pressure on predicting primary graft dysfunction after bilateral lung transplantation for patients with idiopathic pulmonary fibrosis / 中华危重病急救医学

Objective To analyze the value of the potential risk factors on predicting primary graft dysfunction (PGD) after bilateral lung transplantation for the patients with idiopathic pulmonary fibrosis (IPF).Methods A retrospective study was conducted. Fifty-eight patients with IPF who underwent the bilateral lung transplantation admitted to Wuxi People's Hospital Affiliated to Nanjing Medical University from June 2014 to March 2017 were enrolled. The grade 3 PGD happened within 72 hours after transplantation was taken as the outcome event, and these patients were divided into PGD and non-PGD groups. The age, gender, body mass index (BMI), underlying disease, and N-terminal-probrain natriuretic peptide (NT-proBNP) before operation, pulmonary artery systolic pressure (PASP), pulmonary artery diastolic pressure (PADP), and mean pulmonary artery pressure (mPAP) before and after operation, duration of operation, the volume of blood transfusion during operation and postoperation, the use of extracorporeal membrane oxygenation (ECMO) during the operation, blood purification treatment after operation, and shock within 3 days after operation were recorded. The differences of parameters mentioned above between the two groups were compared. The predictive factors of PGD were searched by binary logistic regression analysis, and the receiver operating characteristic curve (ROC) was plotted to analyze the predictive value of preoperative PADP for grade 3 PGD after transplantation.Results Among 58 patients who underwent the bilateral lung transplantation, 52 patients were enrolled. The rest patients were excluded because of incomplete clinical data. There were 17 patients in the PGDgroup, with a mortality rate of 47.06%. The non-PGD group included 35 patients with a mortality rate of 8.57%. PADP and mPAP ahead of operation, the dosage of red cells suspension after the operation, and the total amount of blood transfusion during and after the operation in PGD group were significantly higher than those in non-PGD group [PADP ahead of operation (mmHg, 1 mmHg = 0.133 kPa): 33.7±10.5 vs. 25.3±10.1, mPAP ahead of operation (mmHg): 40.4±14.1 vs. 32.8±11.1, the dosage of red cells suspension after the operation (mL): 700 (300, 1500) vs. 300 (300, 500), the total amount of blood transfusion during and after the operation (mL): 2250 (1850, 4275) vs. 1800 (1550, 2800)], with statistically significant differences (all P 0.05). It was shown by binary logistic regression analysis that the preoperative PADP was the independent risk factor of grade 3 PGD after lung transplantation [odds ratio (OR) = 1.084, 95% confidence interval (95%CI) = 1.016-1.156,P = 0.015]. It was shown by ROC curve that the area under the ROC curve (AUC) of the PADP before operation for predicting the grade 3 PGD after lung transplantation was 0.728. When the cut-off value was 36 mmHg, the sensitivity was 47.1%, and the specificity was 91.4%.Conclusions Compared with the non-PGD group, the patients with higher preoperative PADP were more common in the PGD group, and the patients in the PGD group were more likely to be characterized by grade 3 PGD after lung transplantation. The preoperative PADP was an effective predictor of grade 3 PGD after lung transplantation.

Gait analysis of patients with knee osteoarthritis before and after Chinese massage treatment.

The objective of this study was to evaluate the effectiveness of Chinese massage therapy in patients with knee osteoarthritis (OA) by measuring lower-limb gait parameters. We recruited 20 women with knee OA, who then underwent Chinese massage therapy three times per week for 2 weeks. The patients underwent gait evaluation using a six-camera infrared motion analysis system. They completed Western Ontario and McMaster Universities Osteoarthritis Index questionnaires before and after treatment. We calculated the forward speed, step width, step length, total support time percentage, initial double support time percentage, and single support time percentage. We also measured the angles at the knee, hip, and ankle during the stance phase of walking. The results showed statistically significant mean differences in knee pain relief, alleviation of stiffness, and physical function enhancement after therapy (P < 0.05). The patients gained significantly faster gait speed, greater step width, and increased total support time percentage after the Chinese massage therapy (P < 0.05). There were no significant differences in the range of motion or initial contact angles of the knee, hip, or ankle during the stance phase of walking. We concluded that Chinese massage is a beneficial complementary treatment and an alternative therapy choice for patients with knee OA for short-term pain relief. Chinese massage may improve walking ability for these patients.

Prevention and treatment of primary graft dysfunction after lung transplantation (108 cases report) / 中华器官移植杂志

ObjectiveTo evaluate the prevention and treatment of primary graft dysfunction (PGD) after lung transplantation (LTx).MethodsWe retrospectively analyzed clinical data of108 cases of lung transplantation from September 2002 to June 2011. All the recipients were given continuous monitoring of invasive arterial pressure,pulmonary artery pressure and (or) central venous pressure and artery blood gas analysis and chest X-ray examination postoperatively.The negative fluid balance of the recipients in the first 3 days was maintained.The inspired oxygen (FiO2) or ventilator parameters was adjusted according to the arterial oxygen tension (PaO2) and (or) oxygen saturation,to prevent the occurrence of PGD.Once PaO2/FiO2 sharp decline (less than 200),and chest X-ray showed higher density of the lower transplanted lung fields in the early postoperative period,PGD could be diagnosed when acute rejection,venous anastomotic obstruction,cardiogenic pulmonary edema and pulmonary infections were excluded.According to the standards set by the International Association of Heart and Lung Transplantation,PGD is divided as 0,1,2 and 3.Different levels of PGD were treated by ventilatory support,negative fluid balance,extending the treatment time of the ventilator,the use of pulmonary vasodilators,such as prostaglandin E1and the use of ECMO.Results PGD occurred in10 cases,and the incidence rate was 9.3％. 6 cases were given conventional ventilatory support for (285.8 + 238.6) h (Two cases obtained reversal of PGD,and four cases died) ; the rest four cases were given ECMO (Two cases were supported by ECMO in 24 h after the occurrence of PGD and had a long-term survival after a successful reversal of PGD,and the rest two cases died from acute renal failure and multiple organ failure induced by PGD on the 8th and11th day of the application of ECMO due to the late application of ECMO (after 24 h).ConclusionThe high incidence of PGD causes high mortality perioperatively after lung transplantation.Preventing PGD can improve the survival rate of the lung transplant patients.Once PGD happens,appropriate treatment should be given as soon as possible.
