Profile of Maternal Mortality of COVID-19 in Ceará, in the Period of 2020.

The aim of this paper is to describe the profile of maternal mortality of COVID-19 in the state of Ceará, Brazil, in the period 2020. Ecological, exploratory, cross-sectional study, with secondary data from the Influenza Epidemiological Surveillance Information System, were made available by the Obstetric Observatory Brazilian COVID-19. A total of 485 pregnant and postpartum women were included, and the analysis considered the notifications from the year 2020. The variables of interest and the outcome (death/cure by COVID-19) were analyzed in a descriptive way. Most pregnant and postpartum women were between 20 and 35 years old, brown/white skin color and residing in an urban area. The proportion of deaths was 5.8% in the year 2020. In that period, the rates of hospitalization in the ward increased by 95.5%, 12.6% of hospitalization in the Unit of Intensive Care (ICU), and 7.2% needed invasive ventilatory support. Maternal mortality from COVID-19 suggests an emergency in terms of the development of health actions and policies due to the aggravation and risks due to this disease.

Epsilon wave: A review of historical aspects.

The epsilon wave of the electrocardiogram (ECG) together with fragmented QRS (fQRS), the terminal conduction delay, incomplete right bundle branch block (IRBBB) and complete/advanced RBBB (CRBBB) of peripheral origin are part of a spectrum of ventricular depolarization abnormalities of arrhythmogenic cardiomyopathy(AC). Although the epsilon wave is considered a major diagnostic criterion for AC since 2010 (AC Task Force Criteria), its diagnostic value is limited because it is a sign of the later stage of the disease. It would be more appropriate to say that the epsilon wave is a "hallmark" of AC, but is of low diagnostic sensitivity. Although the epsilon wave has high specificity for AC, it can be present in other pathological conditions. In this update we will cover the nomenclature, association with disease states and electrocardiographic aspects of the epsilon wave.
