Revista Chilena de Obstetricia y Ginecología , 2011,
Abstract: La anemia diseritropoyética congénita se engloba dentro de un grupo raro y heterogéneo de trastornos eritrocitarios caracterizados por eritropoyesis ineficaz, anemia megaloblástica, hemosiderosis secundaria e hidrops fetal. Presentamos el caso de un feto de 20 semanas con hidrops como consecuencia de una anemia fetal intensa por eritropoyesis ineficaz. Ante el hallazgo de hidrops fetal no inmune es fundamental un diagnóstico etiológico precoz para ofrecer a la pareja las alternativas terapéuticas más adecuadas. Congenital dyserythropoietic anemia is a rare group of heterogeneous disorders characterized by ineffective erythropoiesis, megaloblastic anemia, secondary hemosiderosis and fetal hydrops. We report a case of a 20 week old fetus with hydrops as a consequence of a severe fetal anemia resulting from ineffective erythro-poiesis. When non-immune fetal hydrops is found, it is essential an early etiological diagnosis to give the parents the most appropriate therapeutic options.

Abstract: Objetivo: Valorar si existen diferencias en los resultados de los ciclos de FIV-ICSI en función del protocolo de estimulación empleado. Método: Estudio retrospectivo descriptivo de pacientes infértiles que fueron sometidas a ciclos de FIV-ICSI en el Hospital Universitario La Paz, entre los meses de enero y septiembre de 2010, comparando un protocolo largo de estimulación con análogos de GnRH vs un protocolo corto con antagonistas de GnRH. Las variables analizadas fueron: tasa de gestación, necesidad de cancelación del ciclo, dosis total de gonadotropinas requerida durante la estimulación, niveles de estradiol sérico el día de la administración de la hCG, número de folículos puncionados, complejos obtenidos, número de ovocitos maduros y de embriones conseguidos. Resultados: No hubo diferencias estadísticamente significativas en los resultados de los ciclos en función del protocolo de estimulación empleado, en ninguna de las variables analizadas. Conclusiones: Este estudio no encontró diferencias en los resultados de los ciclos de FIV-ICSI con relación al uso de análogos o antagonistas de GnRH. Es necesarios más estudios con mayores tama os muestrales para definir qué tipo de pacientes serían subsidiarias de recibir cada tratamiento para conseguir resultados óptimos. Aims: To assess if there exist any differences in the results of the IVF-ICSI cycles depending on the stimulation protocol employed. Methods: Retrospective descriptive study of infertile patients who underwent IVF-ICSI cycles at La Paz University Hospital, between January and September 2010, comparing sitmula-tion protocol with GnRH agonists vs antagonists of GnRH. The variables analyzed were pregnancy rate, cancellation rate, total dose of gonadotropin required for stimulation, serum estradiol levels on the day of hCG administration, number of follicles punctured, complexes obtained, number of mature oocytes and of embryos obtained. Results: No statistically significant differences where found in the results of cycles depending on the protocol of stimulation used in any of the variables analyzed. Conclusions: This study didn't find any difference in the outcome of IVF-ICSI cycles in relation to the use of GnRH agonists or antagonists. We need more studies with larger sample sizes to determine which is the best treatment to each patient in order to achieve optimal results.

Revista Chilena de Obstetricia y Ginecología , 2011,
Abstract: Objetivo: Analizar la situación actual de la Enfermedad de Chagas (EC) en relación con la gestación en el Hospital Universitario La Paz (HULP). Método: Estudio retrospectivo de gestantes diagnosticadas de EC en el HULP y seguimiento de sus hijos. Resultados: En el HULP hay descritos cinco casos de recién nacidos de madres con EC en seguimiento sin que se haya demostrado transmisión vertical. Discusión: El diagnóstico de la enfermedad en el neonato es complicado debido a la dificultad de detectar parásitos en sangre y a la presencia de anticuerpos maternos. El tratamiento únicamente tiene buenos resultados cuando se administra en los primeros meses de vida. Conclusiones: Debido al aumento de población inmigrante procedente de áreas endémicas, el tamizaje de EC en gestantes procedentes de dichas áreas y el seguimiento de los neonatos es fundamental para facilitar la detección de la infección congénita y su tratamiento. Objective: Analyze the current situation of Chagas' disease in relation with gestation in The University Hospital La Paz (HULP). Methods: Retrospective study of pregnant women diagnosed of Chagas' disease in HULP and the clinical tracking of their children. Results: In the HULP, five cases of new borns with mothers affected of Chagas' disease have been reported without a vertical transmission being detected. Discussion: The diagnosis of Chagas' disease in the new born is complicated because of the difficulty for detecting parasites in blood and the presence of maternal antibodies. Treatment is only effective if it is administered during the first months of life. Conclusions: Due to the increment of immigrant population from endemic areas, the screening of Chagas' disease is really important to detect this congenital infection and its treatment.

Abstract: Learning through aesthetics—in which cinema is included—stimulates learner reflection. Because emotions play key roles in learning attitudes and changing behavior, teachers must impact learners’ affective domain. Since feelings exist before concepts, the affective path is a critical path to the rational process of learning. Likewise, faculty use their own emotions in teaching, so learning proper methods to address their affective side is a complementary way to improve their communication with students. This paper presents experiences of how to use cinema for educating emotions, among students and teachers, to foster reflection and improve teaching skills.

Abstract: objective: to analyze the discourses of primary care midwives on access to and utilization of the cervical cancer prevention program. methods: a qualitative study was conducted in an area of low population density with a high proportion of rural population in segovia, spain, between 2008 and 2009. semi-structured interviews were carried out. ten primary care midwives were interviewed covering the 16 basic health districts of the city. data analysis was based on grounded theory methodology. results: access to and utilization of the cervical cancer prevention program was associated with attendance to midwife visits, women's experiences with cervical smears and their perception of risk of cervical cancer. geographic distance to the health center, difficult access to immigrant women who have no health insurance, and being unaware of the program offered are some of the perceived barriers. social exclusion is also perceived as a barrier of access to and utilization of the program. the recommendation to participate in the program made by the primary care physician was identified as the main facilitator. conclusions: the midwives perceived inequalities in access to and utilization of the cervical cancer prevention program that are associated to individual characteristics of women, and contextual characteristics such as the geographical environment where they live and program's infrastructure. there is inequality of access to care of underrepresented groups of women such as immigrant women and those residing in rural areas.

Content-Level Selective Offloading in Heterogeneous Networks: Multi-armed Bandit Optimization and Regret Bounds
Pol Blasco,Deniz Gündüz
Computer Science , 2014,
Abstract: We consider content-level selective offloading of cellular downlink traffic to a wireless infostation terminal which stores high data-rate content in its cache memory. Cellular users in the vicinity of the infostation can directly download the stored content from the infostation through a broadband connection (e.g., WiFi), reducing the latency and load on the cellular network. The goal of the infostation cache controller (CC) is to store the most popular content in the cache memory such that the maximum amount of traffic is offloaded to the infostation. In practice, the popularity profile of the files is not known by the CC, which observes only the instantaneous demands for those contents stored in the cache. Hence, the cache content placement is optimised based on the demand history and on the cost associated to placing each content in the cache. By refreshing the cache content at regular time intervals, the CC gradually learns the popularity profile, while at the same time exploiting the limited cache capacity in the best way possible. This is formulated as a multi-armed bandit (MAB) problem with switching cost. Several algorithms are presented to decide on the cache content over time. The performance is measured in terms of cache efficiency, defined as the amount of net traffic that is offloaded to the infostation. In addition to theoretical regret bounds, the proposed algorithms are analysed through numerical simulations. In particular, the impact of system parameters, such as the number of files, number of users, cache size, and skewness of the popularity profile, on the performance is studied numerically. It is shown that the proposed algorithms learn the popularity profile quickly for a wide range of system parameters.
