目的了解上海市预防接种工作人员疑似预防接种异常反应(Adverse events following immunization,AEFI)监测的知识和态度以及影响AEFI报告的因素。方法采用方便抽样在上海市所有459个预防接种门诊选择预防接种工作人员开展问卷调查,分析AEFI监测知识得分(满分6分)和态度,采用多因素Logistic回归分析AEFI报告的影响因素。结果1379名调查对象的AEFI监测知识平均得分为3.30±1.31分;认为开展AEFI监测有必要、报告AEFI是自身职责、AEFI监测是额外工作负担的调查对象分别占98.84%、92.75%、30.38%。69.62%的调查对象近1年报告过AEFI;社区接种门诊、免疫规划专职人员、近1年接受过AEFI培训、AEFI监测知识得分高的调查对象报告AEFI的比例高[OR(95%CI):19.55(14.16-26.98)、1.95(1.45-2.64)、3.14(1.76-5.59)、1.91(1.38-2.63)]。结论上海市预防接种工作人员AEFI监测知识水平不高,对AEFI监测存在一定认识误区;需加强AEFI监测培训,进一步提高其AEFI报告意识。 相似文献
Effective nutrition and exercise interventions may improve sarcopenia in the elderly. The purpose of our study was to investigate the effectiveness of Internet-based nutrition and exercise interventions in the elderly with sarcopenia. Participants were divided into 4 groups: control, nutrition, exercise, and comprehensive (nutrition plus exercise) groups; there was at least 50 participants in each group. Our trial lasted 12 weeks. We conducted dietary and exercise interventions through an app and collected feedback from the participants every three weeks. Information on the diet, skeletal muscle mass, and muscle function was collected before and after the interventions. The comprehensive group had higher high-quality protein intake than the control (p = 0.017) and exercise (p = 0.012) groups. After the interventions, we obtained differences in skeletal muscle mass, skeletal muscle mass/height2, skeletal muscle mass/weight, muscle mass/BMI, and skeletal muscle mass/body fat percentage (p < 0.05). Changes in average daily energy and total daily protein intakes were not significantly different; however, there was an overall improvement in the intervention groups relative to baseline data. There were no changes in the average daily time of moderate physical activity. The Internet was an effective tool of nutrition intervention in the elderly with sarcopenia. The Internet-based nutrition intervention improved high-quality protein intake and skeletal muscle mass in the elderly with sarcopenia. 相似文献
A rapid biosensor for the detection of cyromazine in milk is reported based on a fluorescence quenching result. When an FAM labelled G-rich ssDNA Tcy2 is treated with cyromazine, it can form a G-quadruplex-CYR complex and cause a change in fluorescence. As a result, the presence of cyromazine can be determined by fluorescence quenching. This sensor is selective for the detection of cyromazine in raw milk and has a limit of detection of 0.68 ppb and a detection range from 0 to 200 ppb.A rapid biosensor for the detection of cyromazine in milk is reported based on a fluorescence quenching result.相似文献
