    A bridge between geological, mining and archaeological heritage: The Monreal marble quarry (Salamanca, Spain)

    Natural stone has been utilised in the southeastern region of Salamanca province (Spain) since the Chalcolithic period, with the Monreal quarry and its Cream Monreal Marble forming part of this legacy. This study aims to revaluate the Monreal quarry, which is included in the Spanish Inventory of Sites of Geological Interest (IELIG) and currently shows signs of neglect and vandalism. The quarry was operational until recently and remnants of the extraction methods can still be found. The research primarily focuses on the geological and mining educational potential of the site, highlighting its exceptional palaeontological significance and its connections to the area’s archaeological heritage. The Monreal quarry contains the highest concentration of archaeocyaths from the Upper Ovetian (Cambrian Series 2 Stage 3) of the Iberian Peninsula and, hence, Western Europe. This makes it the best outcrop for observing these fossils and understanding these hypercalcified marine animals that inhabited the region about 515 Ma ago. This study reveals for the first time that the Cream Monreal Marble and a Visigothic religious sculpture housed in the Museum of Salamanca are identical in mesoscale, mineralogical composition and isotopic C and O, thereby establishing a significant link between the quarry and the historical heritage of the region. Additionally, a georoute between the Monreal quarry, the Granite Theme Park of Los Santos, and the Iter ab Emerita Asturicam Roman road (UNESCO World Heritage Site) is suggested to facilitate the preservation of the quarry and enhance its geological, palaeontological, mining and cultural values.Ministerio de Ciencia e InnovaciónDepto. de Geodinámica, Estratigrafía y PaleontologíaDepto. de Mineralogía y PetrologíaFac. de Ciencias GeológicasTRUEpu

    Cost-effectiveness impact of rivaroxaban versus new and existing prophylaxis for the prevention of venous thromboembolism after total hip or knee replacement surgery in France, Italy and Spain

    Venous thromboembolism (VTE) has a significant impact on healthcare costs but is largely preventable with anticoagulant prophylaxis using low-molecular-weight heparins (LMWHs), such as enoxaparin or dalteparin. Rivaroxaban and dabigatran etexilate are two new oral anticoagulants (NOACs) both compared with enoxaparin in separate trials. A decision analytic model with a healthcare and national payer perspective over a five-year time horizon was used to evaluate the cost-effectiveness of the NOACs for VIE prophylaxis after total hip replacement (THR) or total knee replacement (TKR) in France, Italy and Spain. Efficacy and safety data were obtained from randomised controlled trials of rivaroxaban vs enoxaparin and an indirect statistical comparison for rivaroxaban vs dabigatran. Rivaroxaban demonstrated dominance across all comparisons, indications and countries. In THR, total per-patient costs were reduced by up to 160 in the enoxaparin comparison and 115 in the dabigatran comparison, respectively. In addition, quality-adjusted life-years (QALYs) were increased by up to 0.0011 and 0.0012 in each comparison, respectively. Similarly, total costs were reduced in TKR by up to 137 and 28 in the enoxaparin and dabigatran comparisons, respectively. The total number of QALYs was increased by up to 0.0014 in the enoxaparin comparison and 0.0005 in the dabigatran comparison. The results were driven by costs since the incremental benefits were minimal. Rivaroxaban use could result in substantial healthcare cost savings and improved quality of life. The results are applicable across three European countries with differing healthcare systems so, potentially, could be generalised to a much wider population
