简介：[摘要] 目的：探讨个性化护理干预在慢性心衰护理中的效果。方法：从2020年1月至2021年3月，来我院治疗的102例慢性心衰患者。根据入院编号奇偶性分组：奇数编号的51例进入对照组，实施心内科护理常规；偶数编号的51例进入试验组，进行个性化护理干预。比较护理依从性和生活质量。结果：试验组依从性优良率更高（96.08%vs84.31%）；两组患者干预后的QOL均明显增高，且试验组评分结果较对照组更高，经检验有统计学差异（P＜0.05）。结论：对慢性心衰患者进行个性化护理干预，能提高护理依从性，有助于改善生活质量。

简介：[摘要] 目的：探讨急性心肌梗死介入治疗中心律失常的护理干预效果。方法：从2020年1月至2021年5月，在我院介入治疗的94例急性心肌梗死患者。根据入院编号奇偶性分组：奇数编号的47例进入对照组，实施常规护理；偶数编号的47例进入试验组，进行有效护理干预。比较护理满意度和治疗指标。结果：相比于对照组，试验组总满意率更高（95.74%vs82.98%），患者的心率、QT离散度更低，QTC间期更大，经检验有统计学差异（P＜0.05）。结论：急性心肌梗死介入治疗中发生心律失常的患者，实施有效护理干预能改善治疗效果，提高患者满意度。

简介：AbstractBackground:The incubation period is a crucial index of epidemiology in understanding the spread of the emerging Coronavirus disease 2019 (COVID-19). In this study, we aimed to describe the incubation period of COVID-19 globally and in the mainland of China.Methods:The searched studies were published from December 1, 2019 to May 26, 2021 in CNKI, Wanfang, PubMed, and Embase databases. A random-effect model was used to pool the mean incubation period. Meta-regression was used to explore the sources of heterogeneity. Meanwhile, we collected 11 545 patients in the mainland of China outside Hubei from January 19, 2020 to September 21, 2020. The incubation period fitted with the Log-normal model by the coarseDataTools package.Results:A total of 3235 articles were searched, 53 of which were included in the meta-analysis. The pooled mean incubation period of COVID-19 was 6.0 days (95% confidence interval [CI]: 5.6-6.5) globally, 6.5 days (95% CI: 6.1-6.9) in the mainland of China, and 4.6 days (95% CI: 4.1-5.1) outside the mainland of China (P=0.006). The incubation period varied with age (P=0.005). Meanwhile, in 11 545 patients, the mean incubation period was 7.1 days (95% CI: 7.0-7.2), which was similar to the finding in our meta-analysis.Conclusions:For COVID-19, the mean incubation period was 6.0 days globally but near 7.0 days in the mainland of China, which will help identify the time of infection and make disease control decisions. Furthermore, attention should also be paid to the region- or age-specific incubation period.
