[The concept map of SENTIERI Project: a communication interactive digital tool of the national epidemiological surveillance system of Italian contaminated sites]. / La mappa concettuale: uno strumento digitale interattivo per la comunicazione del sistema di sorveglianza epidemiologica SENTIERI nei siti contaminati.

This paper describes the development and the envisioned use of concept maps in the framework of the SENTIERI communication strategies as an information and scientific communication tool applied to epidemiological surveillance in contaminated sites. The concept map of SENTIERI 2019-2022 was designed and implemented to foster access to complex scientific information ensuring usability of the contents and communication with the various stakeholders. The concept map aims to promote environmental health literacy in contaminated sites. The methodology adopted to create the map includes the following phases: 1. choice of a dynamic focus question; 2. selection of the representative terms of the addressed topics; 3. elaboration of the glossary of the selected terms; 4. representation of the links among the selected terms; 5. identification of the significant propositions that make explicit the meaning of each link. Online access to the map is guaranteed by the Mindomo software. The use of the concept map promotes active learning of the topics that characterize SENTIERI 2019-2022 through knowledge paths chosen because of the specific interests and learning purposes. The concept map derives from the integration of specific approaches of the epidemiological discipline with those of the social sciences and offers the possibility of developing site-specific maps through the interactions with local actors and the integration of elements related to emerging problems as well as institutional and local interests.

The variants question: What is the problem?

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated in Wuhan, China in early December 2019 has rapidly widespread worldwide. Over the course of the pandemic, due to the advance of whole-genome sequencing technologies, an unprecedented number of genomes have been generated, providing both invaluable insights into the ongoing evolution and epidemiology of the virus and allowing the identification of hundreds of circulating genetic variants during the pandemic. In recent months variants of SARS-CoV-2 that have an increased number of mutations on the Spike protein have brought concern all over the world. These have been called "variants of concerns" (VOCs), and/or "variants of interests" (VOIs) as it has been suggested that their genome mutations might impact transmission, immune control, and virulence. Tracking the spread of emerging SARS-CoV-2 variants is crucial to inform public health efforts and control the ongoing pandemic. In this review, a concise characterization of the SARS-CoV-2 mutational patterns of the main VOCs and VOIs circulating and cocirculating worldwide has been presented to determine the magnitude of the SARS-CoV-2 threat to better understand the virus genetic diversity and its potential impact on vaccination strategy.

The importance of genomic analysis in cracking the coronavirus pandemic.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has pushed the scientific community to undertake intense research efforts. Understanding SARS-CoV-2 biology is necessary to discover therapeutic or preventive strategies capable of containing the pandemic. Knowledge of the structural characteristics of the virus genome and proteins is essential to find targets for therapies and immunological interventions.Areas covered: This review covers different areas of expertise, genomic analysis of circulating strains, structural biology, viral mutations, molecular diagnostics, disease, and vaccines. In particular, the review is focused on the molecular approaches and modern clinical strategies used in these fields.Expert opinion: Molecular approaches to SARS-CoV-2 pandemic have been critical to shorten time for new diagnostic, therapeutic and prevention strategies. In this perspective, the entire scientific community is moving in the same direction. Vaccines, together with the development of new drugs to treat the disease, represent the most important strategy to protect human from viral disease and prevent further spread. In this regard, new molecular technologies have been successfully implemented. The use of a novel strategy of communication is suggested for a better diffusion to the broader public of new data and results.
