The SARS-CoV-2 pandemic challenged the authorities into taking measures that limit the spread of the virus in the community. TAMEC project (Advanced Community Approaches to Epidemic Management) developed a system that detects the contacts of patients infected with the SARS-CoV-2 virus and alerts them using mobile applications. It allows real-time analysis of confirmed patients and identified contacts, early detection of new outbreaks, and provides decisionmaking information to prevent viral transmission. The system uses its patent for homomorphic encryption, a method that allows to process and manipulate data in an encrypted format, without having access to the original data. Thus, the solution proposed in the TAMEC project fully respects the privacy rules of citizens imposed by the EU, using the concept of privacy preservation. Our solution offers the possibility to identify and validate a risk score that could become an extremely helpful tool in the stratification of COVID-19 patients. The TAMEC system is innovative in its simplicity and ability to facilitate the prevention of the spread of the SARS-CoV-2 virus in the community.
Left ventricle systolic function is an essential parameter in different clinical scenarios and the usual methods available for its assessment are sometime suboptimal, depending on the filling conditions of the heart. Therefore, the development and implementation in clinical practice of a new parameter for assessing left ventricle contractile function is desirable. Mechanical work defined as energy transferred to or from an object via the application of force along a displacement seems to be a promising method for myocardial performance estimation. Although initially this parameter was calculated on the left ventricle volume-pressure curve estimated by cardiac catheterization, an easier method considering non-invasive left ventricle pressure and global longitudinal strain assessed by speckle tracking echocardiography was developed recently. Myocardial work offers information regarding the segmental and global function of the left ventricle, and it is considered a more sensitive marker for assessing left ventricle performance compared to ejection fraction and global longitudinal strain. Its applicability in various cardiac pathologies was demonstrated recently in several studies and its use in every day practice may bring important additional information for clinical decision making
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
