RESUMO
Objective:To collect and summarize evidence for improvement of readiness for hospital discharge of patients after PCI.Methods:BMJ Best Practice, UpToDate, Joanna Briggs Institute (JBI) evidence-based health care center database, National Institutes of Health and Clinical Optimization Guidelines Network, Scotland Inter Hospital Guidelines Network, Ontario Registered Nurses Association, International Guidelines Collaboration Network, American Heart Association website, European Heart Association website, Cochrane The literatures about improving the discharge readiness of patients after PCI in library, PubMed, CINAHL, CNKI and Wanfang databases included guidelines, system reviews, best practice information books, evidence summary, expert consensus, and randomized controlled studies. The retrieval time limit was from the establishment of the database to October 2019. Four researchers evaluated the quality of the literature, and extracted evidence from the literature that met the quality standards.Results:A total of 5 articles were included, including 2 guidelines, 2 expert consensus, 1 systematic reviews,3 randomized controlled trials. The best evidence included evaluation of discharge readiness, education of knowledge and skills to patients and caregivers, improvement of self-efficacy of patients and caregivers in disease management, and assurance of social support and health resources for patients and caregivers after discharge.Conclusion:It is suggested that in clinical practice, medical personnel should use the discharge readiness assessment tool to comprehensively evaluate patients after PCI, carry out programmed health education, improve patients' self-efficacy in disease management, and ensure social and medical support for patients and caregivers after discharge as much as possible.
RESUMO
Objective To analyze the biological characteristics of clinical isolates of coxsackievir-us A6 (CVA6), a pathogen of hand,foot and mouth disease (HFMD), and to provide reference for vaccine development. Methods CVA6 strains were isolated from 21 stool and throat swab specimens of patients with HFMD in Yunnan Province and then identified. Their growth characteristics, plaque morphology and virulence to suckling mice were analyzed. Results Five CVA6 strains, named CVA6-129, CVA6-113, CVA6-57, CVA6-94 and CVA6-162, were isolated and all belonged to D3 subtype. Only the CVA6-129 strain could proliferate rapidly in Vero and KMB17 cells and the proliferation peaked 30 h after inoculation. The infectious titer of the CVA6-129 strain was 7. 54 lgCCID50 (50％ cell culture infective dose) / ml in KMB17 cells. Different morphologies of plaques were formed by the CVA6-129 strain in Vero and KMB17 cells at the same time points, which were small and round with clear edges in Vero cells, and large and irregular with blurry edges in KMB17 cells. Suckling mice were susceptible to CVA6 via intramuscular and intraperito-neal injection. The most common symptoms in infected suckling mice were reduced mobility, hind limb pa-ralysis and quadriplegia. CVA6 infection could result in death in severe cases. Conclusions This study isolated five CVA6 strains from a number of clinical samples of suspected HFMD cases, of which the CVA6-129 strain showed potential as a vaccine candidate.
