ABSTRACT
Aims: This study aimed to evaluate the safety and feasibility of computed tomography (CT)-guided synchronous percutaneous core-needle biopsy and microwave ablation (MWA) for highly suspicious malignant pulmonary nodules. Materials and Methods: This retrospective study evaluated medical records of 54 consecutive patients (mean age, 65.5 ± 11.2 years) with 62 highly suspicious malignant pulmonary nodules who synchronously underwent percutaneous core-needle biopsy and MWA via a coaxial cannula (Group A) or sequentially underwent these procedures (Group B) from September 2016 to November 2017. All patients were followed up for at least 6 months after MWA. The safety and feasibility of synchronous core-needle biopsy and MWA were analyzed by comparing clinical data, technical success rate, complication, and curative effect per nodule with those of sequential procedures. Results: Technical success rates were 100% in both groups. The pneumothorax rate was 29.6% (8/27) in Group A and 57.1% (20/35) in Group B, which was statistically different (P = 0.031). In Group A, hemoptysis and pleural effusion rates were 22.2% (6/27), and in Group B, the corresponding rates were 28.6% (10/35) and 20.0% (7/35), respectively. No postprocedural pulmonary artery pseudoaneurysm, bronchopleural fistula, or needle-tract tumor seeding developed in both groups. After 6 months' follow-up, the effective rates (complete + partial response) in both groups were 100%. Conclusions: Synchronous core-needle biopsy and MWA via a coaxial cannula is technically safe and feasible in the management of highly suspicious malignant pulmonary nodules, and this procedure has lesser complications and similar effects (both 100% effective treatment) compared with sequential procedures
ABSTRACT
Objective@#To understand the status of awarences and the influencing factors of food safety among medical students in Shangdong Province,and to provide a reference for improving a healthy eating habit among students on their knowledge about food safety,attitude and behavior.@*Methods@#A total of 2 322 students from 2 medical colleges and universities in Shandong province selected through stratified cluster sampling were investigated with questionnaires.@*Results@#Univariate analysis of variance showed that food safety knowledge differed by gender, grade, major, origin of student, whether learned nutrition knowledge, monthly cost on food (χ2/H=20.48, 128.02, 98.61, 36.50, 77.60, 171.03,P<0.01). In multiple Logistic regression analysis, results showed that gender, major,origin of student, monthly cost on food and the attention of food affect college students’ food safety awareness (P<0.05).@*Conclusion@#Food safety awareness among medical students in Shandong Province is relatively high but varies by multiple factors. It is necessary to improve food safety awareness of medical students through various channels.
