AimsTo assess emergency department (ED) nurses' ability to communicate with angry patients and to explore the factors that influence nurses' communication skills.DesignA cross-sectional survey design.MethodsThis study was conducted in November and December 2020. Stratified sampling was adopted to recruit ED nurses from 18 tertiary hospitals in western, eastern, and central China to complete an online questionnaire. The Nurses' Communication Ability with Angry Patients Scale (NCAAPS) and the General Self-Efficacy Scale were used to assess ED nurses' communication ability and self-efficacy, respectively. Descriptive statistics, the Mann–Whitney U-test, the Kruskal–Wallis H test, Spearman's correlation analysis, and the generalized linear model were used for data analysis.ResultsA total of 679 valid questionnaires were collected. The mean total score for the NCAAPS was (3.79 ± 0.47), while the scores for its four dimensions were (3.87 ± 0.59) for communication skills, (3.82 ± 0.59) for anger perception, (3.79 ± 0.53) for self-preparation, (3.73 ± 0.54) for exploring the cause of anger. The generalized linear regression analysis result showed that a longer employment duration, previous communication ability training, and higher self-efficacy were significantly and independently associated with higher NCAAPS scores (p < 0.05).ConclusionsThe mean total score and the four dimensions score for the NCAAPS were moderate. But there is still room for improvement in ED nurses' ability to communicate with angry patients. “Exploring the cause of anger” was the lowest score among the four dimensions. To improve ED nurses' ability to communicate with angry patients, future studies should focus on constructing specific communication training, improving nurses' ability to explore the cause of anger and self-efficacy.ImpactThe findings of this study provide important insights into ED nurses' ability to communicate with angry patients and can thus guide the future development of intervention programmes to improve this ability among ED nurses.

In order to understand the implementation situation of science popularization education on earthquake prevention and disaster mitigation in the Xiong’an New Area within elementary and secondary school campuses, and students’ cognition and requirements on the knowledge of earthquake prevention and disaster mitigation, the research group selected portion of elementary and secondary schools in three counties of the Xiong’an New Area to carry out questionnaire investigation at the end of 2020. The survey has indicated that elementary and middle school students in the Xiong’an New Area pay a relatively high attention to the knowledge of earthquake prevention and disaster mitigation and have a strong intention of getting involved. They have a high cognitive level of knowledge about earthquake emergency hedge, and they are at the upper-middle level in the aspects of general knowledge of earthquake early warning and earthquake rumor discrimination. And yet their cognition level of post-earthquake relief, self rescue and mutual aid is low. The conventional propaganda models, such as launching lectures on earthquake scientific knowledge propagation and distributing books and brochures, are still the main way to propagate the knowledge of earthquake prevention and disaster mitigation. With the development of network media such as Tik Tok, WeChat and MicroBlog, this sort of propaganda form has widened the channels for science propaganda and is popular among students. This survey provides a certain reference for launching popular science propaganda of earthquake prevention and disaster mitigation in elementary and middle schools in Xiong’an New Area in the future.

Abstract Background Branched chain amino acids (BCAAs) are important substrates for milk protein synthesis in the mammary gland, and are tightly related to lipid metabolism. No study has been performed examining the role of BCAAs with high fat diets on milk fat synthesis. This study was designed to investigate the effect of dietary BCAAs on growth performance of piglets, progeny body weight, and milk fat composition in sows fed a high fat diet. Four diets (CON = control diet; HF = high fat diet with 8% soybean oil; HF-MB=HF plus 0.39% BCAAs; HF-HB=HF plus 0.78% BCAAs) were fed to sows from late gestation to weaning. Results Compared to HF, BCAAs (HF-MB and HF-HB) increased the litter weight (P
