目的本研究旨在以孕产妇死亡率为基础,对相关护理数据和社会背景的因素进行分析,制订临床护理服务资源测量指数。方法采用来源于卫生部、国家统计和地理研究所的数据进行分析,包括:护理覆盖率指数、学士学位及以上护士比例、人类发展指数和人口密度。通过主成分分析法构建墨西哥护理资质指数(Index of Nursing Qualification in Mexico,INQM)。结果INQM与护理覆盖排序指数(The NursingCover-age PrioritisationIndex,NCPI)(0.849,P<0.01)及人口密度排序指数(The Population Density Prioritization in-dex,PDPI)(0.716,P<0.01)相关性均较高。通过主成成分分析提取3个公因子,INQM主要由模型中3个主要成分组成。INQM与孕产妇死亡率之间没有显示有统计学意义的相关关系。结论研究表明,形成INQM的要素可能会对严重的公共卫生问题产生影响,该结果为应用这些指标提供了参考,有助于确定临床护理服务资源测量指数的贡献。

Background: Cardiac involvement and the consequences of inflammation induced by SARS-CoV2 infection could have catastrophic long-term consequences. Left ventricular mechanics could identify a specific pattern of myocardial fiber damage in patients infected with COVID-19. To our knowledge there are no publications referring to the global description of ventricular mechanics in patients with COVID-19. Objective: To describe left ventricular mechanics in hospitalized patients with COVID-19. Methods: In this cross-sectional study, we included 40 hospitalized patients with confirmed diagnostic of COVID-19, from April 11, 2020, to September 6, 2020. Demographic and laboratory data, clinical and echocardiographic characteristics were collected, as well as events during hospitalization. Left ventricular deformation was analyzed and reported. Results: Subclinical dysfunction was observed in 82.5% (left ventricular longitudinal strain [LVGLS] -17.05% and global circumferential strain [GCS] -18.6%) of the patients, likewise, the mean twist and apical rotation were preserved, and even increased as part of the compensating mechanism to maintain the ejection fraction. Conclusion: In patients hospitalized with COVID-19, despite having a normal left ventricular ejection fraction, subclinical myocardial damage was found, manifested by a decrease in Global Longitudinal Strain (GLS) and Global Circumferential Strain (GCS). This behavior is similar to that of cardiomyopathies in the early stage of the disease, and given the pathophysiological mechanisms involved in the disease, its long-term consequences should be monitored and evaluated.
