Pulmonary aspiration is a particularly problematic condition in patients in hospitals and nursing home. To promote patient safety and prevent serious complications, the nurse's role in preventing and caring for patient at high risk of pulmonary aspiration is crucial. Our team has developed an online training system on pulmonary aspiration for nurses to improve their ability to identify early risk factors, scientifically assess the risk of aspiration, and effectively intervene and manage when pulmonary aspiration occurs. This system was developed via WeChat app, the most popular social media application in China. It has four main functions, such as online training, online assessment, announcement interaction, and learning record. This online training systems offer the benefits of flexible learning time with anytime access, rich resources that are easy to update, and greater cost-effectiveness. This paper presents and discusses the development process of this system.

Background: In this study, we sought to assess knowledge, attitudes, and behaviors regarding venous thromboembolism (VTE) prophylaxis among clinicians at a tertiary hospital of China., Methods: An electronic questionnaire was sent to clinicians to gather information regarding demographic data (5 items), knowledge about VTE prophylaxis (21 items), behaviors regarding VTE prophylaxis (8 items), and attitudes regarding VTE prophylaxis (7 items). Answers of "strongly agree" and "agree" on the behaviors and attitude items were defined as affirmative responses. Clinicians were also asked to provide suggestions regarding VTE prophylaxis., Results: A total of 867 clinicians were included in this study. The overall correct response rate for knowledge items was 60.9%. The median affirmative response rate for behavior items was 48.6% (range 29.5-80.3%), and the median affirmative response rate for attitude items was 98.7% (range 96.9-99.3%). Clinicians were most concerned about the adverse effects triggered by chemical VTE prophylaxis (79.5%) and possibility of a financial penalty when a patient could not be treated with VTE prophylaxis (72.3%). Low patient compliance and low level of clinician knowledge and participation were identified most commonly as difficulties involved in VTE prophylaxis. A total of 78 suggestions were collected; these suggestions generally focused on improving the quality and frequency of staff training (n = 24) and enhancing learning opportunities (n = 22)., Conclusions: Although the clinicians' overall attitude toward VTE prophylaxis was positive, the knowledge level was relatively poor, and the rate of affirmative responses regarding behaviors was low. Medical institutions should improve clinician training regarding VTE prophylaxis., (Copyright © 2020. Published by Elsevier Inc.)

Purpose: To retrospectively investigate factors associated with mesenteric artery remodeling after conservative management of isolated mesenteric artery dissection (IMAD) (dissection of the mesenteric arteries in the absence of aortic dissection or other known causes)., Materials and Methods: A total of 107 patients diagnosed with IMAD between February 2010 and October 2018 were identified. Eighteen patients were excluded because they underwent stent placement (n = 11) or were lost to follow-up (n = 7). A total of 89 patients who underwent conservative management were therefore included in the study. Cox regression analysis was performed to identify factors associated with mesenteric artery remodeling., Results: During 15.9 ± 10.9 months of follow-up, complete remodeling of the mesenteric artery was achieved in 66 patients (74.2%), and partial remodeling was achieved in 23 patients (25.8%). Of the 66 patients with complete remodeling, 6 (9.1%) had type IIa IMAD (visible false lumen, no visible re-entry site), and 60 (90.9%) had type IIb IMAD (thrombosed false lumen). The mean interval between IMAD diagnosis and complete remodeling was 14.4 ± 5.4 months for all patients. The mean intervals for patients with type IIa IMAD were 20.0 ± 6.2 months and 13.9 ± 5.1 months for patients with type IIb IMAD (P = .015). Mesenteric artery remodeling was significantly associated with the presence of symptoms (odds ratio, 10.800; 95% confidence interval, 1.961-59.470; P = .006)., Conclusions: Complete remodeling of the mesenteric artery in patients with IMAD treated with conservative management is common, and the presence of symptoms is associated with complete remodeling., (Copyright © 2019 SIR.
