Geodesic Embedded System for Real-Time Tracking and Communication Offline

Nowadays, hybrid (air and land) systems are applied for solving syndemic problems, which have caused millions of deaths by COVID-19. In support to military and medical communications with tracking in real-time, public, or private security of objects and people, we propose a multiplatform Geodesic Embedded System for Real-Time Tracking and communication offline. The Middleware was built with Encrypted Global Navigation Satellite System (GNSS) and DB async replication. It was built under a client-server architecture of multi-Tiers and logical multilayers, was developed with Nodejs-Express-Angular with Object Relational Mapping and Data Transfer Object with PostgreSQL. Generally, tracking systems with GNSS technology are slow without a base architecture and adequate development tools and require an internet connection in some of their stages. The proposed system was tested with other applications;it used Geoserver and Dockers in two different environments. The results showed its functionality in different situations applied in problems of aeronautic and terrestrial tracking, guaranteeing a projection of personalized geodetic maps, and OpenStreetMap used in an agile way, efficient, and secure communication in real-time. The proposed architecture allows native development, integration of new modules, and cross-platform implementation in an easy way, and a cellular transceiver with 94.6% of efficiency. The proposed architecture, permit to use the application in different platforms with the same configuration. [ FROM AUTHOR]

Thrombotic complications of COVID-19.

INTRODUCTION: The novel coronavirus disease of 2019 (COVID-19) is associated with significant morbidity and mortality. The impact of thrombotic complications has been increasingly recognized as an important component of this disease. OBJECTIVE: This narrative review summarizes the thrombotic complications associated with COVID-19 with an emphasis on information for Emergency Medicine clinicians. DISCUSSION: Thrombotic complications from COVID-19 are believed to be due to a hyperinflammatory response caused by the virus. Several complications have been described in the literature. These include acute limb ischemia, abdominal and thoracic aortic thrombosis, mesenteric ischemia, myocardial infarction, venous thromboembolism, acute cerebrovascular accident, and disseminated intravascular coagulation. CONCLUSION: It is important for Emergency Medicine clinicians to be aware of the thrombotic complications of COVID-19. Knowledge of these components are essential to rapidly recognize and treat to reduce morbidity and mortality in these patients.
