New Insights in the Diagnosis and Treatment of Heart Failure

Cardiovascular disease is the leading cause of mortality in the US and in westernized countries with ischemic heart disease accounting for the majority of these deaths. Paradoxically, the improvements in the medical and surgical treatments of acute coronary syndrome are leading to an increasing number of "survivors" who are then developing heart failure. Despite considerable advances in its management, the gold standard for the treatment of end-stage heart failure patients remains heart transplantation. Nevertheless, this procedure can be offered only to a small percentage of patients who could benefit from a new heart due to the limited availability of donor organs. The aim of this review is to evaluate the safety and efficacy of innovative approaches in the diagnosis and treatment of patients refractory to standard medical therapy and excluded from cardiac transplantation lists

Alternatives to Transplantation in the Treatment of Heart Failure: New Diagnostic and Therapeutic Insights

none4siThe aim of our current special issue was to present a series of original researches and reviews on recent advances in the diagnosis, medical therapy, and surgical approaches of heart failure. As reported in the introductive review of Agnetti et al., cardiovascular disease is the leading cause of mortality in the US and in westernized countries with ischemic heart disease accounting for the majority of these deaths. Paradoxically, the improvements in the medical and surgical treatments of acute coronary syndromes are leading to an increasing number of “survivors” who are then developing heart failure. Despite considerable advances in its management, the gold standard for the treatment of end-stage heart failure patients remains heart transplantation. Nevertheless, this procedure can be o ered only to a small percentage of patients who could bene t from a new heart due to the limited availability of donor organs. e authors reported in this comprehensive review the evaluation of the safety and e cacy of innovative approaches in the diagnosis and treatment of patients refrac- tory to standard medical therapy and excluded from cardiac transplantation lists.mixedNicolini, Francesco; Piepoli, Massimo F.; Agnetti, Giulio; Siniscalchi, GiuseppeNicolini, Francesco; Piepoli, Massimo F.; Agnetti, Giulio; Siniscalchi, Giusepp

IDENTIFICATION OF E. COLI O157 IN A BOVINE MILK FARM BY MULTIPLEX REAL-TIME PCR

Law provisions about direct sell of raw bovine milk require VTEC O157 monitoring in bovine milk farms (milk and faeces). It has been showed that culture-based methods used for this scope, besides being cumbersome and time-consuming, may be also less sensitive, compared to molecular approaches. In this study, a multiplex Real-Time PCR, able to identify VTEC O157, Salmonella spp and Listeria monocytogenes, has been used to analyse milk, filter, sewage and stool samples from a milk farm, in comparison with standard OIE methods. The performances of the molecular protocol have been preliminary assessed with lyophilized samples from proficiency testing VLA, showing 100% accordance. Results from field samples indicated the absence of the pathogen in milk, and the higher sensitivity of Real-Time PCR with other matrices, suggesting its potential use for fast VTEC O157 identification

Shear strengthening of masonry panels using a gfrp-reinforced mortar coating

The use of new composite materials for reinforcement of heritage masonry structures, especially in seismic prone areas, is of interest structural engineers and conservators. However, the need to increase the structural performance of masonry structures is often in contrast with the principles of conservation in terms of reversibility, limited visual impact, compatibility of new materials with masonry. With the aim at striking a balance between structural safety and heritage protection, this paper investigates strengthening stone and brickwork masonry walls using glass-fiber reinforced polymer (GFRP) meshes embedded into a coating of lime or cement mortar. An experimental research program was undertaken in the laboratory on large-scale wall panels. Both clay brick and stone work specimens were tested, with and without strengthening. Single-sided and double-sided strengthenings were considered, as it is often not practicable to apply the reinforcement to both sides of a wall. Static tests were carried out on twelve masonry panels, under in-plane diagonal shear loading. The mechanisms by which load was carried were observed, varying from the initial, uncracked state, to the final, fully cracked state. The results demonstrate that a significant increase of the in-plane shear capacity of masonry can be achieved by using the proposed retrofitting technique. The experimental data were used to assess the effectiveness of the strengthening, and a finite element (FE) numerical model is discussed and calibrated against experimental results. The FE model was used to investigate further aspects of the reinforced masonry under shear-loading

The RainBO Platform for Enhancing Urban Resilience to Floods: An Ecient Tool for Planning and Emergency Phases

Many urban areas face an increasing flood risk, which includes the risk of flash floods. Increasing extreme precipitation events will likely lead to greater human and economic losses unless reliable and efficient early warning systems (EWS) along with other adaptation actions are put in place in urban areas. The challenge is in the integration and analysis in time and space of the environmental, meteorological, and territorial data from multiple sources needed to build up EWS able to provide efficient contribution to increase the resilience of vulnerable and exposed urban communities to flooding. Efficient EWS contribute to the preparedness phase of the disaster cycle but could also be relevant in the planning of the emergency phase. The RainBO Life project addressed this matter, focusing on the improvement of knowledge, methods, and tools for the monitoring and forecast of extreme precipitation events and the assessment of the associated flood risk for small and medium watercourses in urban areas. To put this into practice, RainBO developed a webGIS platform, which contributes to the “planning” of the management of river flood events through the use of detailed data and flood risk/vulnerability maps, and the “event management” with real-time monitoring/forecast of the events through the collection of observed data from real sensors, estimated/forecasted data from hydrologic models as well as qualitative data collected through a crowdsourcing app
