Abstract Purpose To investigate the prognostic value of the factors related to the initial surgical management of burn wounds in severely burned patients. Methods A total of 189 severely burned adult patients who were admitted to our institute between January 2012 and December 2020 and met the inclusion criteria were recruited. Patients were divided into survival and nonsurvival groups. The patient data included sex, age, total burn surface area (TBSA), burn index (BI), inhalation injury, mechanical ventilation, initial surgical management of the burn wound (including post-injury time before surgery, surgical duration, surgical area, intraoperative fluid replenishment, intraoperative blood loss, and intraoperative urine output), and duration in the burn intensive care unit (BICU). Independent samples t tests, Mann-Whitney U tests, and χ 2 tests were performed on these data. those of which with statistically significant differences were subjected to univariate and multivariate Cox regression analyses to identify independent risk factors affecting the prognosis of severely burned patients. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC), optimal cut-off value were calculated. Patients were divided into two groups, according to the optimal cut-off value of the independent risk factors. The TBSA, surgical area and survival rates of the two groups during hospitalization were analysed. Results The survival group (146 patients) and the nonsurvival group (43 patients) differed significantly in TBSA, burn index, inhalation injury, mechanical ventilation, initial surgical area, intraoperative fluid replenishment, intraoperative blood loss, and duration in the BICU (P<0.05). Univariate Cox regression analysis showed that TBSA, burn index, mechanical ventilation, initial surgical area, intraoperative fluid replenishment, and intraoperative blood loss were risk factors for death in severely burned patients (P<0.05). Multivariate Cox regression analysis showed that the burn index and intraoperative blood loss were independent risk factors for death in severely burned patients (P<0.05). When the intraoperative blood loss during the initial surgical management of burn wounds was used to predict death in 189 severely burned patients, the AUC was 0.637 (95% confidence interval (CI): 0.545-0.730, P=0.006), and the optimal cut-off for intraoperative blood loss was 750 ml. Kaplan-Meier survival analysis showed that the prognosis of the group with intraoperative blood loss ≤750 ml was better than that of the group with intraoperative blood loss >750 ml (P=0.008). Meanwhile, the TBSA and surgical area in the group with intraoperative blood loss ≤750 ml were significantly lower than that of the group with intraoperative blood loss >750 ml (P<0.05). Conclusion The burn index and intraoperative blood loss during the initial surgical management of burn wounds are independent risk factors affecting the outcome of severely burned patients with good predictive values. During surgery, haemostatic and anaesthetic strategies should be adopted to reduce bleeding, and the bleeding volume should be controlled within 750 ml to improve the outcome.

Background: The aim of our study was to develop a nomogram model to predict overall survival (OS) and cancer-specific survival (CSS) in patients with gastric signet ring cell carcinoma (GSRC). Methods: GSRC patients from 2004 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly assigned to the training and validation sets. Multivariate Cox regression analyses screened for OS and CSS independent risk factors and nomograms were constructed. Results: A total of 7,149 eligible GSRC patients were identified, including 4,766 in the training set and 2,383 in the validation set. Multivariate Cox regression analysis showed that gender, marital status, race, AJCC stage, TNM stage, surgery and chemotherapy were independent risk factors for both OS and CSS. Based on the results of the multivariate Cox regression analysis, prognostic nomograms were constructed for OS and CSS. In the training set, the C-index was 0.754 (95% CI = 0.746-0.762) for the OS nomogram and 0.762 (95% CI: 0.753-0.771) for the CSS nomogram. In the internal validation, the C-index for the OS nomogram was 0.758 (95% CI: 0.746-0.770), while the C-index for the CSS nomogram was 0.762 (95% CI: 0.749-0.775). Compared with TNM stage and SEER stage, the nomogram had better predictive ability. In addition, the calibration curves also showed good consistency between the predicted and actual 3-year and 5-year OS and CSS. Conclusion: The nomogram can effectively predict OS and CSS in patients with GSRC, which may help clinicians to personalize prognostic assessments and clinical decisions.

Abstract Background: Metabolic syndrome (MS) could promote the development of cardiovascular disease(CVD). The aim of this study was to examine the association of MS and its components with CVD among Kazakhs in Xinjiang. Methods: According to the geographical distribution of the minority populations in Xinjiang, we selected the representative prefecture (Yili). A total of 2,644 participants completed the baseline survey between April 2010 and December 2012. The follow-up survey was conducted from April 2016 to December 2016. Only 2,286 out of 2,644 participants were followed-up on, with a follow-up rate of 86.46%. Cox regression was used to evaluate the association of each component and the number of combinations of MS components on the development of CVD. Results: Multivariate Cox regression analysis showed that blood pressure (BP), waist circumference (WC), and triglycerides (TG) were independently associated with CVD. Participants with 1–5 MS components had an increased hazard ratio for developing CVD, from 1.82 to 8.59 (trend P<0.001), compared with those without any MS components. This trend persisted after adjusting for other general risk factors. The risk of developing CVD increased when TG and WC coexisted, or when TG/WC and BP coexisted. However, no significant interactions were found between BP , WC , and TG. Conclusions: BP , WC, and TG were independent risk factors for CVD in Kazakhs. In clinical practice, a more informative assessment may be obtained by taking into account the number of MS components.

Abstract Backgrounds: The prognosis of thoracic aortic pseudoaneurysm (TAP) after thoracic endovascular aortic repair (TEVAR) remains unclear. This study investigates the early and midterm clinical outcome as well as relevant risk factors of TAP patients following TEVAR therapy.Methods: From July 2010 to July 2020, 37 eligible TAP patients who underwent TEVAR were selected into our research. We retrospectively explored their baseline, perioperative and follow-up data. Fisher exact test and Kaplan-Meier method were applied for comparing difference between groups. Risk factors of late survival were discerned using Cox regression analysis.Results: There were 29 men and 12 women, with the mean age as 59.5±13.0 years (range, 30-82). The mean follow-up time was 30.7±28.3 months (range, 1-89). For early result, early mortality (≦30days) happened in 3(8.1%) zone 3 TAP patients versus 0 in zone 4 (p= 0.028); acute arterial embolism of lower extremity and type II endoleak respectively occurred in 1(2.7%) case. For midterm result, survival at 3 months, 1 year and 5 years was 88.8±5.3%, 75.9±7.5% and 68.3±9.9%, which showed significant difference between zone 2/3 versus zone 4 group (56.3±14.8% versus 72.9±13.2%, p= 0.013) and emergent versus elective TEVAR groups (0.0±0.0% versus 80.1±8.0%, p= 0.049). On multivariate Cox regression, lesions at zone 2/3 (HR 4.605, 95%CI 1.095-19.359), concomitant cardiac disease (HR 4.932, 95%CI 1.086-22.403) and emergent TEVAR (HR 4.196, 95%CI 1.042-16.891) were significant independent risk factors for worse late clinical outcome. Conclusions: TEVAR therapy is effective and safe with satisfactory early and midterm clinical outcome for TAP patients. Lesions at zone 2/3, concomitant cardiac disease and emergent TEVAR were independent risk factors for midterm survival outcome.

Abstract BACKGROUND: Trauma is a damage caused by physical harm from external source. It has been one of the major causes of mortality. The purpose of this study was to explore the risk factors related to mortality among emergency trauma patients. METHODS: This was a retrospective study in trauma center of the First Affiliated Hospital of Soochow University. The data were obtained from trauma database with patients registered from November 1, 2016 to November 30, 2019.Shapiro–Wilk test, Mann-Whitney test and Likelihood-ratio Chi squared test were used to assess the survival pattern. Cox regressions were performed to calculate the hazard ratios (HRs) of variables for death. RESULTS: The total 1739 emergency trauma patients, 44 (2.53%) died during the study period and 1695 (97.47%) were survival. Through univariable and multivariable Cox regression analysis, three independent risk factors for emergency death were screened out: pulse (Crude HR: 0.97, 95% Confidence Interval [CI]: 0.96-0.98; Adjuste HR: 1.04, 95% CI: 1.02-1.06), pulse oxygen saturation (Crude HR: 0.96, 95% CI: 0.95-0.97; Adjuste HR: 0.94, 95% CI: 0.91-0.97) and Revised Trauma Score (Crude HR: 0.69, 95% CI: 0.65-0.74; Adjuste HR: 0.79, 95% CI: 0.64-0.97).CONCLUSION: The survival outcome of emergency trauma patients was influenced by many factors. Pulse, pulse oxygen saturation (SpO2 ) and Revised Trauma Score (RTS) were the independent risk factors for mortality. Accurate analysis and judgment of the risk factors can improve cure efficiency and long-term survival rate.

Background: This presented study was aimed to evaluate the diagnostic and prognostic value of PD-L1+Neutrophils (PD-L1+NEUT) and neutrophil to lymphocyte ratio (NLR) based on our previous experience of Foxp3+Treg in transplantation. Methods: the NLR cutoff value of 1.79 was used to include 136 cases from the 204 patients with hepatocellular carcinoma (HCC) confirmed by clinical pathology, which were divided into highly-moderately and poorly differentiated HCC groups. The expressions of PD-L1+NEUT and Foxp3+Treg in peripheral blood and cancer tissue were detected with flow cytometry, meanwhile, PD-L1 and Foxp3 expressed in carcinoma and para-carcinoma tissues were marked by immunohistochemistry. Survival rates, including overall survival and disease-free survival, were calculated by the Kaplan–Meier curve and evaluated with the log-rank test. Finally, Cox risk regression model was used to analyze the independent risk factors for prognostic survival. Results: The level of PD-L1+NEUT, Foxp3+Treg, and NLR in peripheral blood of patients with poorly differentiated HCC were significantly increased (all P < .001). Both PD-L1+NEUT and NLR were positively correlated with Foxp3+Treg ( r = 0.479, P = .0017; r = 0.58, P < .0001). The level of PD-L1+NEUT and Foxp3+Treg as well as PD-L1 and Foxp3 in cancer tissue and patients with poorly differentiated HCC were obviously increased (all P < .01), respectively. Cox regression analysis indicated that PD-L1+NEUT, NLR, and Foxp3+Treg were independent risk factors for the prognosis ( P = .000, .000, .006) with a RR and 95%CI of 2.704-(2.155-3.393), 3.139-(2.361-4.173), 1.409-(1.105-1.798), respectively. Conclusion: PD-L1+NEUT, NLR, and Foxp3+Treg are independent risk factors for prognosis which maybe new marker of lower survival benefits.

OBJECTIVE: To identify risk factors influencing outcomes of bronchial arterial embolisation (BAE) in tuberculosis (TB) related haemoptysis.METHODS: A cohort of 207 patients underwent BAE for TB-related haemoptysis between March 2014 and March 2018. The clinical data were reviewed. Follow-up ranged from 24 to 1749 days.RESULTS: Immediate haemostasis rate was 94.2%; aggressive pleural thickening (PT) was found to be a risk factor for haemoptysis (P = 0.000, OR 22.52). Cumulative recurrence-free rates were respectively 98.5%, 94.8%, 88.7%, 79.9%, 68.5%, 65.7% and 62.7% for 1, 3, 6, 12, 24, 36 and 48 months. Respectively 8 and 15 patients recovered from pneumonectomy and re-BAE. However, five patients required a third BAE. The Cox regression analysis indicated that aggressive PT (P = 0.000), diabetes mellitus (DM) (P = 0.018) and pulmonary fungal infection (PFI) (P = 0.001) were independent risk factors for recurrence. The death rate following BAE was 9.2%; aggressive PT was a risk factor (P = 0.000, OR 8.14).CONCLUSION: BAE is effective for TB-related haemoptysis in most cases. Aggressive PT, DM and PFI are independent risk factors influencing the prognosis following BAE. PFI and DM should be well managed, while proper surgery should be considered for aggressive PT.

Abstract Objective: The purpose of this study was to identify the relationship between coagulopathy during the perioperative period (before the operation and on the first day after the operation) and the long-term survival of TBI patients undergoing surgery, as well as to explore the predisposing risk factors that may cause perioperative coagulopathy.Methods: This retrospective study included 447 TBI patients who underwent surgery from January 1, 2015 to April 25, 2019. Clinical parameters, including patient demographic characteristics, biochemical tests, perioperative coagulation function tests (before the operation and on the first day after the operation) and intraoperative factors were collected. Log-rank univariate analysis and Cox regression models were conducted to assess the relationship between perioperative coagulopathy and the long-term survival of TBI patients. Furthermore, univariate and multivariate analyses were performed to identify the underlying risk factors for perioperative coagulopathy.Results: Multivariate Cox regression analysis identified age, AIS(head) = 5, GCS ≤ 8, systolic pressure at admission < 90 mmHg and postoperative coagulopathy (all P < 0.05) as independent risk factors for survival following TBI; we were the first to identify postoperative coagulopathy as an independent risk factor. According to multivariate logistic regression analysis, for the first time, abnormal ALT and RBC at admission, preoperative coagulopathy, infusion of colloidal solution > 1100 mL and intraoperative bleeding > 950 mL (all P < 0.005) were identified as independent risk factors for postoperative coagulation following surgery after TBI.Conclusions: Those who suffered from postoperative coagulopathy due to TBI had a higher hazard for poor prognosis than those who did not. Closer attention should be paid to postoperative coagulopathy and more emphasis should be placed on managing the underlying risk factors.

Abstract Introduction: Strong evidence is lacking to support effectiveness of currently implemented tuberculosis infection prevention control (TB-IPC) measures for preventing nosocomial tuberculosis (TB) transmission. This 13-year analysis is the longest follow-up investigation to date to identify risk factors underlying nosocomial TB transmission. Methods: We monitored all staff of Beijing Chest Hospital each year from 2006 to 2018. Age, gender, duration, department, education, income, respirator, ultraviolet, and ventilation were chosen as variables. Univariate cox regression, correlation analysis, and multivariate cox regression were analyzed sequentially.Results: Using multivariable cox regression analysis, variables of income, ultraviolet germicidal irradiation (UVGI), natural ventilation and mechanical ventilation conferred significant protective effects, with odds ratios (ORs) of 0.499, 0.058, 0.003, and 0.015, respectively (P<0.05). Medical N95 respirator conferred an excellent protective effect, with an associated TB infection rate of 0%. Notably, inadequately maintained mechanical ventilation systems were less protective than natural ventilation systems.Conclusions: UVGI, adequate ventilation, and use of medical N95 respirator may be risk factors of nosocomial TB transmission.

Objective: This study aims to evaluate the clinical application of preoperative prealbumin-to-fibrinogen ratio (PFR) in the clinical diagnosis and prognostic value of hepatocellular carcinoma (HCC) patients. Methods: The clinical and laboratory data of 269 HCC patients undergoing surgical treatment from January 2012 to January 2017 in Taizhou Hospital were retrospectively analyzed. The Cox regression model was used to analyze the correlation between PFR and other clinicopathologic factors in overall survival (OS) and disease-free survival (DFS). Results: Cox regression analysis showed that PFR (hazard ratios [HR] = 2.123; 95% confidence interval [95% CI], 1.271–3.547; P = 0.004)was independent risk factors affecting the OS of HCC patients. Furthermore, a nomogram was built based on these risk factors. The C indices statistics for the OS nomogram was 0.715. Conclusion: Nomograms based on PFR can be recommended as the correct and actual model to evaluate prognosis for patients with HCC.

Objective: This study aimed to analyze the characteristics and reasons of early discontinuation of obsessive-compulsive disorder (OCD) trials registered on ClinicalTrials.gov.Methods: OCD trials and relevant publications were searched on ClinicalTrials.gov and PubMed, respectively. The characteristics and details regarding the timely publication of trials were recorded. Cox regression analysis was used to explore factors associated with the early discontinuation of OCD trials.Results: The analysis included 298 OCD therapy trials. Most investigations recruited &lt;100 patients and were more likely to involve adults. Of all OCD studies identified, 67.8% were randomized and 61.4% were blind (single- or double-blind). Universities and hospitals were recorded as the two primary locations in the majority of trials. A total of 155 trials (52%) were completed; however, only 29% of those were published. Of the published trials, &gt;70% were published at least 1 year after completion. Behavioral therapy trials were the most common type of major treatment-aimed OCD trials (39%), followed by drug trials (35.1%) and device/procedure trials (24.7%). The univariate Cox regression analysis indicated that drug trials [hazard ratio (HR) = 2.56, 95% confidence interval (CI): 1.21–5.43], absence of collaborators (HR = 3.87, 95% CI: 1.62–9.26), and sponsorship by industry (HR = 3.97, 95% CI: 1.49–10.53) were risk factors for early discontinuation of OCD trials. Further multivariate Cox regression showed that drug trials (HR = 3.93, 95% CI: 1.71–9.08) and absence of collaborators (HR = 5.17, 95% CI: 1.97–13.54) were independent risk factors for early trial discontinuation of OCD trials. The sensitivity analysis confirmed these results. Non-drug trials (OR = 3.32, 95% CI: 1.21–9.11), absence of collaborators (OR = 3.25, 95% CI: 1.10–9.60), and non-blinded trials (OR = 5.23, 95% CI: 1.05–26.2) were independent risk factors for unreported results in registry.Conclusion: The diagnosis and prevention of OCD are rarely investigated in trials. Underreporting and delayed reporting remain major problems. The type of intervention and participation of collaborators are associated with early discontinuation of OCD trials.
