Cocaine is the second most consumed illegal drug in the western world, following cannabis. Since 1998, it is also the drug that more attendances generate in different emergency devices, and it is responsible for more of 60% of the emergencies directly related to drug consumption. This work reviews the main Spanish scientific articles published in the last 10 years, in which different factors related to the use of this drug have been analyzed in relation to the use of emergency by cocaine users. A total of 8,795 patients were included (interval 57-1,755), with an average age of 32.64 years (SD 3.02), and an average percentage of positives to cocaine of 54.78% (SD 47.03); there were 7 works with 100% of subjects being positive to cocaine. Males predominated with an average of 78.69% (SD 12). They presented cardiovascular symptoms in 30% cases (SD 22.7), neurological symptoms in 11.6% cases (SD 4.28) and psychiatric symptoms in 49.32% cases (SD 23.87). There was a multiple consumption in 49.02% of patients (interval 4.3-76.2), fundamentally associated with alcohol (57.78%, SD 6.18) and cannabis (21.56%, SD 10.72). Two hundred and forty-six patients (2.8%) needed admission and 8 died (0.09%). © 2013 Elsevier España, S.L.U.

Diagnosing acute coronary syndrome (ACS) in the emergency department is often a complex process. Inflammatory markers might be useful for the rapid assessment of a patient’s overall risk and might also help predict future episodes. The clinical use of these biomarkers could potentially lower the number of emergency visits and help in the prevention of future adverse events. The aim of this review was to evaluate the clinical utility of markers of cardiovascular inflammation in emergency patients with ACS. Based on a critical analysis of a selection of the literature, we concluded that none of the biomarkers of cardiovascular inflammation would at present be useful for stratifying risk in emergency situations, aiding prognosis, or guiding therapy for patients with ACS. © 2015 (publisher).

Spain has been working on improving the competitiveness of its tourist destinations, focusing on the quality of the service. This paper analyzes whether the efforts made by the tourism establishment to achieve the Q brand are perceived by their guests in a general way or in a particular dimension of the service. Statistical contrasts of mean differences are performed to evaluate if the score of a Q hotel is greater than that of a non-Q hotel. The results show that the Q brand is related to the satisfaction of the customer in a different way according the analyzed dimension.

Transforming a city into a smart city is a long and complex process. If the aim is to modify large areas (regions / territories), the problem becomes significantly harder. Contrary to what might be expected, combining N smart cities within the same territory will not necessarily lead to a smart region. Although there are several smart-region experiments of an international nature, there is still no benchmark to facilitate this task. One possible reason for this is the varied and specific characteristics of each region. In the case of island territories, this task is made less complex due to the common problems that characterize them. This paper analyzes these characteristics, seeks common patterns and proposes a model for the smart development of island territories in an effort to harmonize and optimize the available resources by providing for smart planning that is more orderly, uniform and efficient. © 2016 ACM.

Early age shrinkage and cracking, water permeability and carbonation depth of concretes with natural Pozzolans blended cement (NPC) were investigated in order to assess the combined effect of Polypropylene short fibers (PPF) and Silica Fume (SF) on some durability parameters. The addition of 10% of SF increased compressive strength, shrinkage and cracking, permeability and carbonation depth. But, the combination of 10% SF and 0.07% PPF volumetric fraction mitigated early age cracking and significantly reduced water permeability and carbonation depth. The use of PPF in NPC concrete combined with SF can be recommended to reduce long-term impact of early age cracking, and enhance durability. However, cement should not be reduced when SF is added to mixtures without PPF, because lower CaO reserves may affect final pH, leading to concretes more sensible to carbonation. © 2015 Elsevier Ltd.
