ABSTRACT
Objective:To investigate the effect of intravenous anesthesia on the detection rate of lesions in diagnostic gastroscopy.Methods:A total of 9 071 subjects who underwent diagnostic gastroscopy at the Digestive Endoscopy Center of Yangzhou University Affiliated Hospital from March 2021 to February 2022 were selected. Data were collected from the gastroscopy quality control system, including age, gender, examination physician, Helicobacter pylori infection, examination method, withdrawal time, number of images left, number of biopsies, biopsy site, gastroscopy diagnosis, pathological diagnosis, etc. They were divided into anesthesia group and general group based on the examination method, and propensity score matching (PSM) was performed on the two groups of subjects. Excluding confounding factors, the detection of lesion location and lesion type in two groups of subjects was analyzed; Simultaneously, univariate and multivariate logistic regression analysis was used to analyze the influencing factors of the detection rate of precancerous lesions and malignant tumors in the upper gastrointestinal tract.Results:After PSM, 1 655 subjects were included in both groups. In terms of lesion location, the detection rate of gastric body lesions in the anesthesia group was higher than that in the general group ( P<0.05), and the detection rate of esophageal lesions in the anesthesia group was lower than that in the general group ( P<0.05); In terms of lesion types, the detection rate of precancerous lesions such as gastric polyps, mucosal protrusions, mucosal atrophy, and intestinal metaplasia in the anesthesia group was higher than that in the general group (all P<0.05). The results of logistic regression analysis showed that intravenous anesthesia was an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy ( OR=1.338, 95% CI: 1.070-1.674, P<0.05). Conclusions:Intravenous anesthesia is an independent influencing factor for the detection rate of precancerous lesions and malignant tumors in diagnostic gastroscopy, and can improve the detection rate of upper gastrointestinal lesions.
ABSTRACT
Objective@#To explore the effects and mechanism of humble leadership on organizational trust and voice behavior of nursing staff.@*Methods@#A total of 249 questionnaires were collected with a questionnaire survey, the effective response rate was 91.54%. The structural equation model was used to test the relationship between variables.@*Results@#The humble leadership had a significantly positive influence on the organizational trust (β= 0.46, P<0.01) and voice behavior (β= 0.63, P<0.01) of nursing staffs, organizational trust played the partial mediating effect (β= 0.29, P<0.01).@*Conclusion@#A nursing manager who is good at humble behavior can promote organizational trust among the subordinate nursing team, which in turn, directly and indirectly enhances their positive voice behavior.
ABSTRACT
Objective To explore the accuracy of endoscopic ultrasonography (EUS) for evaluating T3 esophageal squamous cell carcinoma (ESCC).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 733 patients diagnosed with T3 ESCC by preoperative EUS who were admitted to the Sun Yat-sen University Cancer Center from January 2003 to December 2015 were collected.All the patients underwent radical resection of ESCC.The postoperative pathological stage as a gold standard,the accuracy,overstaged and understaged rates of clinical staging by preoperative EUS were assessed.Observation indicators:(1) comparison between clinical T staging evaluated by preoperative EUS and postoperative pathological T staging;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect patients' diseases and postoperative survival up to December 30,2016.Overall survival time was from operation time to death or last effective follow-up.Measurement data with normal distribution were represented as (x)±s.Measurement data with skewed distribution were described as M (range).Count data were represented as cases and percentage.The survival curve was drawn by the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Results (1) Comparison between clinical T staging evaluated by preoperative EUS and postoperative pathological T staging:all the 733 patients were confirmed as T3 ESCC by preoperative EUS.Postoperative pathological diagnosis showed that 9 patients were detected in pT1b,87 in pT2,630 in pT3 and 7 in pT4a.The accuracy,overstaged and understaged rates of preoperative EUS in evaluating T3 ESCC were 85.95％(630/733),13.10％(96/733) and 0.95％(7/733),respectively.N0,N1,N2 and N3 of postoperative pathological N stage were respectively detected in 329,247,110 and 47 patients.Twenty-seven,323 and 383 patients were in stage Ⅰ,Ⅱ and Ⅲ of TNM stage,respectively.The high-,moderate-and lowdifferentiated tumors were respectively detected in 125,403 and 205 patients.(2) Follow-up and survival situations:among 733 patients,639 were followed up for 1.0-153.0 months,with a median time of 29.0 months.The median survival time,1-,3-,5-year overall survival rates were 53.0 months (range,37.7-68.3 months),85.3％,58.1％ and 48.2％ in 733 patients,respectively.The 5-year overall survival rate was 75.2％ in 9 patients with pT1b,63.0％ in 87 patients with pT2,46.3％ in 630 patients with pT3 and 0 in 7 patients with pT4a,respectively,with a statistically significant difference (x2=24.089,P＜0.05).Conclusion There is a higher accuracy of EUS for evaluating T3 ESCC,however,the stage migration should be noted.
