Wearable proximity sensors for monitoring a mass casualty incident exercise: a feasibility study

Over the past several decades, naturally occurring and man-made mass casualty incidents (MCI) have increased in frequency and number, worldwide. To test the impact of such event on medical resources, simulations can provide a safe, controlled setting while replicating the chaotic environment typical of an actual disaster. A standardised method to collect and analyse data from mass casualty exercises is needed, in order to assess preparedness and performance of the healthcare staff involved. We report on the use of wearable proximity sensors to measure proximity events during a MCI simulation. We investigated the interactions between medical staff and patients, to evaluate the time dedicated by the medical staff with respect to the severity of the injury of the victims depending on the roles. We estimated the presence of the patients in the different spaces of the field hospital, in order to study the patients' flow. Data were obtained and collected through the deployment of wearable proximity sensors during a mass casualty incident functional exercise. The scenario included two areas: the accident site and the Advanced Medical Post (AMP), and the exercise lasted 3 hours. A total of 238 participants simulating medical staff and victims were involved. Each participant wore a proximity sensor and 30 fixed devices were placed in the field hospital. The contact networks show a heterogeneous distribution of the cumulative time spent in proximity by participants. We obtained contact matrices based on cumulative time spent in proximity between victims and the rescuers. Our results showed that the time spent in proximity by the healthcare teams with the victims is related to the severity of the patient's injury. The analysis of patients' flow showed that the presence of patients in the rooms of the hospital is consistent with triage code and diagnosis, and no obvious bottlenecks were found

A Self-Powered Wireless Water Quality Sensing Network Enabling Smart Monitoring of Biological and Chemical Stability in Supply Systems

A smart, safe, and efficient management of water is fundamental for both developed and developing countries. Several wireless sensor networks have been proposed for real-time monitoring of drinking water quantity and quality, both in the environment and in pipelines. However, surface fouling significantly affects the long-term reliability of pipes and sensors installed in-line. To address this relevant issue, we presented a multi-parameter sensing node embedding a miniaturized slime monitor able to estimate the micrometric thickness and type of slime. The measurement of thin deposits in pipes is descriptive of water biological and chemical stability and enables early warning functions, predictive maintenance, and more efficient management processes. After the description of the sensing node, the related electronics, and the data processing strategies, we presented the results of a two-month validation in the field of a three-node pilot network. Furthermore, self-powering by means of direct energy harvesting from the water flowing through the sensing node was also demonstrated. The robustness and low cost of this solution enable its upscaling to larger monitoring networks, paving the way to water monitoring with unprecedented spatio-temporal resolution.

Containing the accidental laboratory escape of potential pandemic influenza viruses

BACKGROUND: The recent work on the modified H5N1 has stirred an intense debate on the risk associated with the accidental release from biosafety laboratory of potential pandemic pathogens. Here, we assess the risk that the accidental escape of a novel transmissible influenza strain would not be contained in the local community. METHODS: We develop here a detailed agent-based model that specifically considers laboratory workers and their contacts in microsimulations of the epidemic onset. We consider the following non-pharmaceutical interventions: isolation of the laboratory, laboratory workers’ household quarantine, contact tracing of cases and subsequent household quarantine of identified secondary cases, and school and workplace closure both preventive and reactive. RESULTS: Model simulations suggest that there is a non-negligible probability (5% to 15%), strongly dependent on reproduction number and probability of developing clinical symptoms, that the escape event is not detected at all. We find that the containment depends on the timely implementation of non-pharmaceutical interventions and contact tracing and it may be effective (>90% probability per event) only for pathogens with moderate transmissibility (reproductive number no larger than R(0) = 1.5). Containment depends on population density and structure as well, with a probability of giving rise to a global event that is three to five times lower in rural areas. CONCLUSIONS: Results suggest that controllability of escape events is not guaranteed and, given the rapid increase of biosafety laboratories worldwide, this poses a serious threat to human health. Our findings may be relevant to policy makers when designing adequate preparedness plans and may have important implications for determining the location of new biosafety laboratories worldwide

Etruscan tin : a legend ?

This is a refutation of the assertion which claims some form of mining of tin ore (cassiterite) from the deposits of the Campigliere (Livorno) area in the Etruscan period. As a matter of fact, there is to this day no concrete evidence of such mining activity in those deposits until the Roman era. It is highly probable that they were exploited only for their iron ores, on reason of their low tin grade and the admixture of several other metals (iron, copper, arsenic, bismuth), which made its cleansing highly complex.Remise en cause de l'affirmation selon laquelle il y aurait eu de l'extraction de minerai d'étain (cassitérite) dans les gisements du Campigliere (Livourne) à l'époque étrusque. En réalité, il n'y a pas à ce jour de preuves concrètes d'une telle activité d'extraction dans ces gisements jusqu'à l'époque romaine. Il est plus que probable qu'ils n'aient été exploités que pour leurs minerais de fer, en raison de leur faible teneur en étain et du mélange qu'on y trouvait de plusieurs autres métaux (fer, cuivre, arsenic, bismuth), ce qui en rendait la dépuration fort complexe.Tizzoni Marco.

I marchi delle spade La Tène conservate al Civico Museo Archeologico di Milano

La récente révision des matériaux du deuxième âge du Fer du Musée archéologique de Milan a conduit à la découverte d'estampilles sur certaines lames d’épées laténiennes des phases moyenne et récente : deux épées de Nosate (prov. de Milan ) portent un sanglier et un croissant de lune, deux de Magenta (prov. de Milan), un sanglier et un symbole complexe, difficile à interpréter ; enfin, de deux épées de provenance inconnue, l’une porte deux estampilles — sanglier et croissant lunaire —, la seconde une marque impossible à identifier.Tizzoni Marco.
