Abstract: gastroesophageal reflux (ger) is common in infants during the early months of life, as a result of a weak development of the regulatory mechanisms. nevertheless, ger tends to disappear as infants grow. nowadays, ger has become a common cause ofpediatric consultation in the clinical practice, especially if it is followed by vomits. sometimes, changing baby position while feeding seems to be a solution to reduce symptoms, while other times it is necessary manage the problem according to clinical practice guidelines. in these guidelines, the use of anti-regurgitation infant formulas are included, which has been formulated with thickening agents and/or whey/casein ratio modification. antiregurgitation milk products are available without pediatric prescription in chemists and other authorized establishments. published studies on antiregurgitant infant formulas show some contradictory conclusions about their use. a negative effect on mineral and micronutrient bioavailability has been proposed by some authors, in relation to the presence of thickening agents used as ingredients. different aspects which require more research, related to the use of antiregurgitation infant formulas, have been included in this review with the aim ofproducing more effective and safety products for an especially vulnerable population, where an optimum feeding will lead to an adequate development and good health status in the future.

Abstract: Las regurgitaciones gastroesofágicas en el lactante constituyen un proceso frecuente en los primeros meses de vida, fruto de la inmadurez de algunos mecanismos fisiológicos que regulan este proceso, con tendencia a desaparecer conforme avanza el desarrollo. Constituyen un motivo de consulta pediátrica frecuente, sobre todo cuando se acompa an de vómitos. En ocasiones, las recomendaciones posturales a adoptar durante la alimentación son suficientes para contribuir a mejorar la sintomatología. Cuando esto es insuficiente, existen protocolos de intervención en nutrición infantil como el dise o de fórmulas antirregurgitación, que contienen sustancias espesantes y/o modificaciones en la relación suero:caseína. Las fórmulas antirregurgitación se encuentran disponibles en farmacias y otros establecimientos de venta autorizados, sin que sea necesaria una prescripción médica para su adquisición. Estudios realizados sobre el empleo de fórmulas infantiles para el manejo pediátrico del reflujo gastroesofágico muestran ciertas contradicciones respecto a una recomendación sobre su uso. Algunos autores destacan que puede aparecer un efecto negativo sobre la biodis-ponibilidad mineral y de otros micronutrientes como consecuencia de los agentes espesantes utilizados como ingredientes. En la presente revisión se abordan los aspectos que, sobre el empleo de fórmulas infantiles antiregurgitación, precisan de mayor investigación para permitir elaborar fórmulas antirregurgitación eficaces y totalmente seguras para una población que es especialmente vulnerable, y en la que una correcta alimentación permite un adecuado desarrollo y buen estado de salud en la etapa adulta.

Abstract: Mobile phones have been proclaimed as the new service frontier. Nowadays, in addition to traditional mobile services, new mobile commerce services are ready to be used by customers based on 3G-related technologies. However, little is known about the reasons why different groups of customers adopt mobile commerce services. By means of a sample of 542 Dutch consumers, we analyze the acceptance of these services by four different groups of customers. We finish our work providing interesting conclusions for academics as well as practitioners
Photogrammetric Methodology for the Production of Geomorphologic Maps: Application to the Veleta Rock Glacier (Sierra Nevada, Granada, Spain)

Remote Sensing , 2009, DOI: 10.3390/rs1040829
Abstract: In this paper we present a stereo feature-based method using SIFT (Scale-invariant feature transform) descriptors. We use automatic feature extractors, matching algorithms between images and techniques of robust estimation to produce a DTM (Digital Terrain Model) using convergent shots of a rock glacier.The geomorphologic structure observed in this study is the Veleta rock glacier (Sierra Nevada, Granada, Spain). This rock glacier is of high scientific interest because it is the southernmost active rock glacier in Europe and it has been analyzed every year since 2001. The research on the Veleta rock glacier is devoted to the study of its displacement and cartography through geodetic and photogrammetric techniques.

Abstract: Informal care is today the form of support most commonly used in Spain by those who need help in order to carry out basic daily activities. The potential labour opportunity costs incurred by Spanish informal carers have not as yet been quantified. In this paper we use the Spanish subsample of the European Community Household Panel (1994–2001) to estimate an econometric model which we exploit to examine the effects of various types of informal care on labour market outcomes. Our results reveal the existence of non-negligible costs in terms of foregone employment for carers who live with the dependent person and/or provide more than 28 h of care/week. We also find that providing care for more than a year has negative effects on employment. Nonetheless, there seems to be no contemporaneous employment effects associated to either starting or ending an episode of care.

Abstract: Objetivo: Se valoran los efectos que tendría una intervención destinada a reducir el uso de tabaco en la población espa ola de fumadores sobre la morbilidad, la mortalidad y los costes asociados al consumo de tabaco. Método: Se ha adaptado el modelo Health and Economic Consequences of Smoking patrocinado por la OMS y desarrollado por The Lewin Group. La intervención propuesta incluye el acceso a asistencia farmacológica de un 35% de los fumadores que intentan dejar de fumar, y obtienen una tasa global de cesación al a o del 7,2%. Las enfermedades estudiadas son: cáncer de pulmón, enfermedad coronaria, enfermedad cerebrovascular, EPOC, asma y bajo peso al nacer. Se estiman los casos de enfermedad y muerte atribuibles al consumo de tabaco evitados y la reducción en el coste sanitario debidos a la intervención, proyectados a 20 a os. Resultados: Sin intervención, en el a o 1 del modelo 2.136.094 fumadores padecen alguna de las condiciones clínicas atribuibles al consumo de tabaco, el coste asistencial es de 4.286 millones de euros y las muertes atribuibles son 26.537. La intervención propuesta evita 2.613, 9.192, 17.415 y 23.837 casos de enfermedad atribuible al consumo de tabaco en los a os 2, 5, 10 y 20 del modelo, respectivamente. Los costes asistenciales acumulados evitados son 3,5 millones de euros en el a o 2 y 386 millones de euros a los 20 a os. Las muertes acumuladas evitadas son 284 en el a o 2 y 9.205 a los 20 a os de la intervención. La intervención a ade un total de 78.173 a os de vida al final del período considerado. Conclusiones: La disponibilidad de nuevas intervenciones eficaces en el tratamiento del tabaquismo y el incremento de la accesibilidad a las mismas pueden contribuir de forma relevante a la reducción de la morbilidad, la mortalidad y los costes sanitarios asociados al tabaquismo en Espa a.

LA CIUDAD COMO ESPACIO POLíTICO SUSTENTABLE
Nicolás E. López Tamayo
Quivera , 2010,
Abstract: La ciudad es un problema político antes que ecológico ya que su construcción ha sido producto de la acción de múltiples individuos agrupados en actores y agentes sociales con intereses contradictorios. Estos se han expresado en el territorio de distintas manera y han producido a la ciudad y su territorio de influencia. El trabajo se estructura en tres partes. En la primera se plantea la sustentabilidad y su perspectiva política. La segunda ejemplifica algunas contradicciones en el desarrollo de la ciudad de Puebla. En la tercera se proponen algunas líneas de acción hacia la sustentabilidad política del espacio en la ciudad.
