ObjectiveTo analyze the risk factors affecting delayed gastric emptying (DGE) after laparoscopic distal gastrectomy for gastric cancer. MethodsThe gastric cancer patients who underwent laparoscopic distal gastrectomy in the Jiaozuo People’s Hospital from January 1, 2013 to December 31, 2022 were retrospectively collected. The occurrence of DGE was recorded. Meanwhile, the multivariate binary logistic regression analysis was performed to screen the risk factors affecting the DGE. ResultsA total of 350 gastric cancer patients underwent laparoscopic distal gastrectomy and met the inclusion and exclusion criteria of this study were included, 17 (4.9%) of whom developed DGE. The multivariate binary logistic regression analysis results showed that the preoperative gastric outflow tract obstruction (OR=8.582, P=0.009), intraoperative jejunal nutrition tube indwelling (OR=14.317, P=0.010), more peritoneal drainage tube placement (OR=5.455, P=0.006), and intraoperative blood loss ≥140 mL (OR=4.912, P=0.018) increased the risk of DGE. ConclusionAccording to the results of this study, when patients undergoing laparoscopic distal radical gastrectomy for gastric cancer accompanied by preoperative gastric outflow tract obstruction, intraoperative jejunal nutrition tube indwelling, more peritoneal drainage tube placement, and more intraoperative blood loss, it should be paid more attention to prevention DGE, and early detection and treatment, so as to improve the prognosis of patients.
Objective To assess the risk factors associated with postoperative infection after elective abdominal operation for elderly in department of general surgery. Methods One hundred and fifty-nine consecutive elderly patients admitted to the department of general surgery in our hospital for elective abdominal operation between May 2010 and February 2012 were considered for inclusion and retrospectively analyzed. Thirty-eight patients （23.90%）with postoperative infection were taken as the infection group and 121 patients without postoperative infection as noninfection group. The differences in the objective physiological indicators， subjective health status indicators， operation status， the incidence of postoperative infective complications， and mortality were compared between the two groups. Results Of enrolled 159 patients in this study， the incidence of postoperative infective complications was 23.90% （38/159）； 2 patients died， and the postoperative mortality rate was 1.26%. Single factor and multivariate logistic regression analysis showed that preoperative malnutrition risk， history of diabetes， and chronic respiratory system disease were the independent risk factors of postoperative infection complications in elective abdominal surgery for elderly patients. Conclusion Improving preoperative respiratory function， diabetes mellitus， and nutritional status would help to reduce incidence of postoperative infection for elderly patients with elective abdominal operation.
ObjectiveTo explore the association between wearing dentures and the risk of head and neck cancer using meta-analysis. MethodsPubMed, EMbase, CNKI, and WanFang Data were searched up to April 30th, 2014, for cohort studies and case-control studies about the association between wearing dentures and the risk of head and neck cancer. Literature screening according to the inclusion and exclusion criteria, data extraction and methodological quality assessment of included studies were completed by two reviewers independently. Then meta-analysis was conducted using Comprehensive Meta-Analysis v 2.2 software. ResultsEight case-control studies in 7 reports were finally included. The results of meta-analysis revealed that, low-degree association existed between wearing dentures and the risk of head and neck cancer (OR=1.08, 95%CI 1.00 to 1.16); and the results of further subgroup analysis (according to gender, cancer lesions, confounders adjustment, and publication years) also showed no significant difference. ConclusionWearing dentures is not significantly associated with the risk of head and neck cancer (no difference regarding gender or cancer lesions). Due to limitations of this meta-analysis, high-quality studies with large sample size are needed to further verify the above conclusion.
ObejectiveTo summarize the research progress of risk factors contributing to postoperative pulmonary infection in gastric cancer, so as to provide reference for medical decision-makers and clinical practitioners to effectively control the incidence of postoperative pulmonary infection in gastric cancer, ensure medical safety and improve the quality of life of patients. MethodThe researches at home and abroad on the factors contributing to pulmonary infection after gastric cancer surgery in recent years were reviewed and analyzed. ResultsThere was currently no uniform diagnostic standard for pulmonary infection. The incidence of postoperative pulmonary infection for gastric cancer varied in the different countries and regions. The pathogenic bacteria that caused postoperative pulmonary infection of gastric cancer was mainly gram-negative bacteria, especially Pseudomonas aeruginosa, Escherichia coli, Acinetobacter boulardii, and Klebsiella pneumoniae. The patient’s age, history of smoking, preoperative pulmonary function, preoperative laboratory indicators, preoperative comorbidities, preoperative nutritional status, preoperative weakness, anesthesia, tumor location, surgical modality, duration of surgery, blood transfusion, indwelling gastrointestinal decompression tube, wound pain, and so on were possible factors associated with postoperative pulmonary infection of gastric cancer. ConclusionsThe incidence of postoperative pulmonary infection for gastric cancer is not promising. Based on the recognition of related factors, it is proposed that it is necessary to develop a risk prediction model for postoperative pulmonary infection of gastric cancer to identify high-risk patients. In addition to the conventional intervention strategy, taking the pathogenesis as the breakthrough, finding the key factors that lead to the occurrence of postoperative pulmonary infection of gastric cancer is the fundamental way to reduce its occurrence.

ObjectiveTo use machine learning technology to predict the recurrence of atrial fibrillation (AF) after radiofrequency ablation, and try to find the risk factors affecting postoperative recurrence. MethodsA total of 300 patients with valvular AF who underwent radiofrequency ablation in West China Hospital and its branch (Shangjin Hospital) from January 2017 to January 2021 were enrolled, including 129 males and 171 females with a mean age of 52.56 years. We built 5 machine learning models to predict AF recurrence, combined the 3 best performing models into a voting classifier, and made prediction again. Finally, risk factor analysis was performed using the SHApley Additive exPlanations method. ResultsThe voting classifier yielded a prediction accuracy rate of 75.0%, a recall rate of 61.0%, and an area under the receiver operating characteristic curve of 0.79. In addition, factors such as left atrial diameter, ejection fraction, and right atrial diameter were found to have an influence on postoperative recurrence. ConclusionMachine learning-based prediction of recurrence of valvular AF after radiofrequency ablation can provide a certain reference for the clinical diagnosis of AF, and reduce the risk to patients due to ineffective ablation. According to the risk factors found in the study, it can provide patients with more personalized treatment.

ObjectiveTo investigate the risk factors affecting cervical central lymph node metastasis (CLNM) and lateral lymph node metastasis (LLNM) in patients with papillary thyroid carcinoma (PTC). MethodsThe patients with newly diagnosed with PTC who underwent surgical treatment in this hospital from April 2020 to December 2023 were included. The univariate and multivariate logistic regression analyses were conducted to identify the risk factors affecting the occurrences of CLNM and LLNM in patients with PTC and a prediction model was developed using these risk factors. Additionally, the discriminatory power of the predictive model for CLNM or LLNM was evaluated using the area under the receiver operating characteristic curve (AUC). ResultsA total of 297 patients with PTC were included in this study, among whom 149 (50.2%) cases developed CLNM, and 41 (13.8%) cases developed LLNM. The multivariate analysis indicated that the male, age <36 years old, and maximum tumor diameter >5 mm were the independent risk factors for CLNM in the patients with PTC (P<0.05). The independent risk factors for LLNM in the patients with PTC were the age ≥59 years old, bilateral or isthmus distribution of cancer foci, maximum tumor diameter >5 mm, and invasion of capsule (P<0.05). The AUC (95%CI) of the CLNM prediction model, constructed using three risk factors (gender, age, and maximum tumor diameter), was 0.693 (0.633, 0.752). For the LLNM prediction model, which incorporated four factors [age, distribution of cancer foci, maximum tumor diameter, and capsular invasion], the AUC (95%CI) was 0.776 (0.707, 0.846). ConclusionsThe findings of this study suggest that younger male patients with PTC (age <36 years), and a maximum tumor diameter >5 mm have a higher risk of CLNM. However, the predictive model constructed for CLNM demonstrates only moderate discriminatory power. In contrast, elderly patients (age ≥59 years old) with PTC exhibiting a maximum tumor diameter >5 mm, capsular invasion, and bilateral (or isthmus) lesions are at greater risk of LLNM. The predictive model developed for LLNM shows a certain discriminatory performance.
Objective A comparative study of in-hospital mortality and risk factors of ventilator-associated pneumonia (VAP) caused by carbapenem-resistant gram-negative bacteria (CRGNB) and non-carbapenem-resistant gram-negative bacteria (nCRGNB) in China was conducted to investigate whether there is a higher in-hospital mortality of VAP caused by CRGNB and its unique associated risk factors. Methods Relevant literatures published at home and abroad in PubMed, EMBASE, Cochrane library, Web of Science, CNKI and Wanfang databases were retrieved from the date of establishment to June 1, 2021, and the quality of the included literatures was evaluated using Newcastle-Ottawa scale. Meta-analysis of literatures meeting the criteria was performed using RevMan 5.3 software. Results A total of 5 literatures were included, all of which were case-control studies with a total of 574 cases, including 302 cases in the CRGNB group and 272 cases in the nCRGNB group. The results showed that the in-patient mortality of VAP caused by CRGNB infection was significantly increased compared with that of VAP caused by nCRGNB infection (OR=2.51, 95%CI 1.71 - 3.67, P<0.00001). Risk factor analysis of CRGNB infection showed that statistically significant risk factors included mechanical ventilation duration ≥7 days (OR=2.66, 95%CI 1.23 - 5.75, P=0.01), secondary intubation (OR=4.48, 95%CI 2.61 - 7.69], P<0.00001), combined with antibiotics (OR=2.83, 95%CI 1.76 - 4.54, P<0.0001), using carbapenem antibiotics (OR=2.78, 95%CI 1.76 - 4.40, P<0.0001). In addition, two studies showed that tigecycline was sensitive to CRGNB in vitro. Conclusions Compared with nCRGNB-induced VAP, CRGNB infection significantly increases the in-hospital mortality of VAP patients in China, indicating that the in-hospital mortality of CRGNB infection is related to drug resistance, and had little relationship with region and drug resistance mechanism. Among them, mechanical ventilation duration ≥7 days, secondary intubation, combined use of antibiotics and carbapenem antibiotics are risk factors for CRGNB infection in VAP patients. Tigecycline is sensitive to most CRGNB strains in China and is an important choice for the treatment of CRGNB in China.
ObjectiveTo explore the relation between preoperative serum gamma-glutamyl transpeptidase to platelet ratio (GPR) and overall survival (OS) of patients with hepatitis B virus-associated hepatocellular carcinoma (Abbreviated as “patients with HCC”), and to establish a nomogram for predicting OS. MethodsAccording to the inclusion and exclusion criteria, the clinicopathologic data of patients with HCC who underwent radical resection in the Department of Hepatobiliary Surgery of Xianyang Central Hospital, from January 15, 2012 to December 15, 2018, were retrospectively analyzed. The optimal critical value of GPR was determined by receiver operating characteristic curve, then the patients were divided into a low GPR group (GPR was optimal critical value or less ) and high GPR group (GPR was more optimal critical value). The Kaplan-Meier method was used to draw the survival curve and analyze the OS of patients. The univariate and multivariate Cox proportional hazards regression model were used to analyze the factors influencing prognosis in the patients with HCC. According to the risk factors of OS for patients with HCC, a nomogram was established. The consistency index and calibration curve in predicting the 3-year and 5-year accumulative OS rates of patients with HCC were evaluated. ResultsA total of 213 patients were gathered. The optimal critical value of GPR was 0.906. There were 114 patients in the low GPR group and 99 patients in the high GPR group. The Kaplan-Meier survival curve analysis showed that the 1-, 3- and 5-year accumulative OS rates were 99.1%, 81.8%, 60.6% in the low GPR group, respectively, which were 74.2%, 49.1%, 35.7% in the low GPR group, respectively. The OS curve of the low GPR group was better than that of the high GPR group (χ2=25.893, P<0.001). The multivariate analysis results showed that the microvascular invasion, incomplete capsule, intraoperative bleeding ＞1 000 mL, postoperative complications, GPR >0.906, low tumor differentiation, and late TNM stage did not contribute to accumulative OS in the patients with HCC (P<0.05). The consistency index (95%CI) of the nomogram in predicting accumulative OS rates at 3- and 5-year for patients with HCC were 0.761 (0.739, 0.783) and 0.735 (0.702, 0.838), respectively. The calibration curves of 3- and 5-year accumulative OS rates of the nomogram were in good agreement with the actual results. ConclusionsPreoperative GPR is associated with OS, and patients with higher GPR have worse prognosis. The nomogram based on GPR has a good accuracy and differentiation.
