    Restoration of abandoned agricultural lands toward habitats for umbrella species

    This study analyzes the suitability of agricultural lands with risk of abandonment for restoration to suitable habitats for animal species of conservation interest. As a case study, the main focus was on olive plantations (Olea europaea L.) of mountainous areas of Southern Spain and the Iberian lynx (Lynx pardinus Temminck, 1827). The method weighs the judgement of experts on the effect of landscape elements on the habitat via an analytic hierarchy process and spots areas most suitable for restoration through geographical information systems. The results suggest that the edge of major agricultural areas and areas with natural vegetation adjacent to the Natural Park of Sierra de Cardeña and Montoro would be most suitable for restoration of the lynx habitat. The precise location of olive groves suitable for restoration are discussed, as revealed by experts� decision-making processes. The main interest of the study relies on the potential of the method to combine territorial analysis with biological requirements of endangered species to facilitate their dispersal.El presente estudio analiza la idoneidad de zonas agrícolas con riesgo de abandono para su restauración como hábitat de especies animales de interés. Como caso de estudio se considera las plantaciones olivareras (Olea europaea L.) de montaña del sur de España y el lince ibérico (Lynx pardinus). La metodología pondera la opinión de un grupo de expertos sobre el efecto que los diferentes elementos del paisaje tienen sobre el hábitat del lince, integrándose posteriormente en un sistema de información geográfica. Los resultados sugieren que las zonas olivareras lindantes con el Parque Natural de la Sierra de Cárdena y Montoro y zonas con vegetación natural existente serían las más adecuadas para su restauración. Si bien la exacta localización de las zonas más adecuadas está sujeta a discusión, como demuestran las divergencias en la opinión de los expertos, el interés principal del estudio radica en la potencialidad del enfoque metodológico, el cual combina el análisis territorial y requerimientos biológicos específicos, para la conservación y dispersión de especies de interés

    Neonatal encephalopathy secondary to birth asphyxia, the hypoxic ischemic encephalopathy, remains a major cause of postnatal death and neurological sequelae worldwide. Supportive therapy has been the mainstay of treatment. Recently series of multicenter clinical trials show the benefits of therapeutic hypothermia in this high risk population. The International Liaison Committee on Resuscitation (ILCOR) has recommended hypothermia as a standard of care and a beneficial therapy using the protocols followed in large clinical trials. Our objective was to develop a practical guide to be used at a national level in Chile, compatible with published protocols and standardized on an international basis, practical and compatible with the country's situation, and considering an integral management of the asphyxiated neonates, rescue and neuroprotective therapies. In summary, to establish rescue therapies, with the aim objective of support measures that promote cerebral and systemic oxygenation/p

    MRI predicts intracranial hemorrhage in patients who receive long-term oral anticoagulation

    OBJECTIVE: We tested the hypothesis that the risk of intracranial hemorrhage (ICH) in patients with cardioembolic ischemic stroke who are treated with oral anticoagulants (OAs) can be predicted by evaluating surrogate markers of hemorrhagic-prone cerebral angiopathies using a baseline MRI. METHODS: Patients were participants in a multicenter and prospective observational study. They were older than 64 years, had a recent cardioembolic ischemic stroke, and were new users of OAs. They underwent a baseline MRI analysis to evaluate microbleeds, white matter hyperintensities, and cortical superficial siderosis. We collected demographic variables, clinical characteristics, risk scores, and therapeutic data. The primary endpoint was ICH that occurred during follow-up. We performed bivariate and multivariate Cox regression analyses. RESULTS: We recruited 937 patients (aged 77.6 +/- 6.5 years; 47.9% were men). Microbleeds were detected in 207 patients (22.5%), moderate/severe white matter hyperintensities in 419 (45.1%), and superficial siderosis in 28 patients (3%). After a mean follow-up of 23.1 +/- 6.8 months, 18 patients (1.9%) experienced an ICH. In multivariable analysis, microbleeds (hazard ratio 2.7, 95% confidence interval [CI] 1.1-7, p = 0.034) and moderate/severe white matter hyperintensities (hazard ratio 5.7, 95% CI 1.6-20, p = 0.006) were associated with ICH (C index 0.76, 95% CI 0.66-0.85). Rate of ICH was highest in patients with both microbleed and moderate/severe WMH (3.76 per 100 patient-years, 95% CI 1.62-7.4). CONCLUSION: Patients taking OAs who have advanced cerebral small vessel disease, evidenced by microbleeds and moderate to severe white matter hyperintensities, had an increased risk of ICH. Our results should help to determine the risk of prescribing OA for a patient with cardioembolic stroke. CLINICALTRIALSGOV IDENTIFIER: NCT02238470
