Treatment of cancer with oral drugs: a position statement by the Spanish Society of Medical Oncology

Cancer treatment involves the participation of multiple medical specialties and, as our knowledge of the disease increases, this fact becomes even more apparent. The degree of multidisciplinarity is determined by several factors, which include the severity and type of disease, the increasing diversity in the available pharmacological and non-pharmacological therapies, and the range of specialists involved in cancer therapy, such as medical oncologists, radiotherapists, gynecologists, gastroenterologists, urologists, surgeons, and pneumologists, among others. Across Europe, the situation of cancer care can be variable due to the diversity of health systems, differences in drug reimbursement, and the degree of establishment of Medical Oncology as a medical specialty in the European Union states.

Broadening the CRM domain of application to higher educational (e-learning) environments

In this paper, we reflect about the broadening of the field of application of CRM from the business domain to a wider context of relationships in which the inclusion of non-profit making organizations seems natural. In particular, we focus on analyzing the suitability of adopting CRM processes by universities and higher educational institutions dedicated to e-learning. This is an issue that, in our opinion, has much potential but has received little attention in research so far.

Hibridación entre la codorniz común (Coturnix coturnix) y la codorniz de granja: estado de un problema de conservación

Hibridación entre la codorniz común (Coturnix coturnix) y la codorniz de granja: estado de un problema de conservación. La hibridación entre especies es un fenómeno ampliamente extendido que puede tener consecuencias en la conservación de la biodiversidad. En el presente artículo se hace una revisión del problema de conservación derivado de la suelta de codornices de granja en poblaciones silvestres de codorniz común (Coturnix coturnix). Estas codornices de granja han resultado ser híbridos de codorniz común y codorniz japonesa (Coturnix japonica). Si no existen mecanismos de aislamiento reproductor, estas sueltas favorecerían la introgresión de genes de codorniz japonesa en las poblaciones de codorniz común; ello conllevaría que se produjera un"enjambre de híbridos" y la sedentarización de las poblaciones de codorniz, lo que comportaría muy probablemente su disminución en Europa. Esta amenaza es real, al haberse demostrado que no hay mecanismos de aislamiento reproductor, ni pre-cigóticos, ni post-cigóticos, ni ecológicos. Sin embargo, datos empíricos sugieren que a pesar de ello no se produce el temido"enjambre de híbridos", sugiriéndose una mortalidad diferencial entre las dos especies como una posible explicación. Finalmente, se sugieren algunas medidas de gestión derivadas de la situación actual, entre las que destacaría un control genético que certifique el origen de los individuos criados en granja y la prohibición de efectuar sueltas de codornices japonesas o híbridos.

Detectings low introgression of invasive alleles in an extensively restocked game bird

Interbreeding of two species in the wild implies introgression of alleles from one species into the other only when admixed individuals survive and successfully backcross with the parental species. Consequently, estimating the proportion of first generation hybrids in a population may not inform about the evolutionary impact of hybridization. Samples obtained over a long time span may offer a more accurate view of the spreading of introgressed alleles in a species" gene pool. Common quail (Coturnix coturnix) populations in Europe have been restocked extensively with farm quails of hybrid origin (crosses with Japanese quails, C. japonica). We genetically monitored a common quail population over 15 years to investigate whether genetic introgression is occurring and used simulations to investigate our power to detect it. Our results revealed that some introgression has occurred, but we did not observe a significant increase over time in the proportion of admixed individuals. However, simulations showed that the degree of admixture may be larger than anticipated due to the limited power of analyses over a short time span, and that observed data was compatible with a low rate of introgression, probably resulting from reduced fitness of admixed individuals. Simulations predicted this could result in extensive admixture in the near future.

Identification and conservation of remnant genetic resources of brown trout in relict populations from Western Mediterranean streams

Brown trout is a cold-adapted freshwater species with restricted distribution to headwater streams in rivers of the South European peninsulas, where populations are highly vulnerable because Mediterranean regions are highly sensitive to the global climatic warming. Moreover, these populations are endangered due to the introgressive hybridization with cultured stocks. Individuals from six remnant populations in Western Mediterranean rivers were sequenced for the complete mitochondrial DNA control region and genotyped for 11 nuclear markers. Three different brown trout lineages were present in the studied region. Significant genetic divergence was observed among locations and a strong effect of genetic drift was suggested. An important stocking impact (close to 25%) was detected in the zone. Significant correlations between mitochondrial-based rates of hatchery introgression and water flow variation suggested a higher impact of stocked females in unstable habitats. In spite of hatchery introgression, all populations remained highly differentiated, suggesting that native genetic resources are still abundant. However, climatic predictions indicated that suitable habitats for the species in these rivers will be reduced and hence trout populations are highly endangered and vulnerable. Thus, management policies should take into account these predictions to design upstream refuge areas to protect remnant native trout in the region
