[Haiti, new immigrant community in Chile]. / Haití, la nueva comunidad inmigrante en Chile.

Migration is a growing phenomenon in Latin America influenced by several factors such as economic stability, employment, social welfare, education and health system. Currently Chile has a positive migration flow rate. Particularly, a significant number of Haitian immigrants has been observed du ring the last years, especially after earthquake of 2010. These immigrants present a different cultural background expressed in relevant aspects of living including parenting and healthcare. Knowing the Haitian culture and its health situation is relevant for a better understanding of their health needs. Haitian people come to Chile looking for a cordial reception and willing to find a place with better perspectives of wellbeing in every sense. Immigration represents a major challenge for Chilean health system that must be embraced. Integration efforts in jobs, health, education system and community living should be enhanced to ensure a prosper settlement in our country. A new immigration law is crucial to solving major problems derived from current law created in 1975.

Haití, la nueva comunidad inmigrante en Chile / Haiti, new immigrant community in Chile

Las migraciones constituyen un fenómeno creciente en América Latina, influido por factores económicos, laborales, búsqueda de bienestar social, educación y salud, entre otros. Chile presenta una tasa neta de migración positiva, y en el último tiempo ha destacado el gran número de inmigrantes haitianos que han llegado a nuestro país, especialmente luego del terremoto que le afectó el 2010. Provenientes de una cultura diferente, donde el estilo de crianza y las características de atención en salud, entre otros aspectos, difieren a la de nuestro país, conocer la cultura haitiana y su situación de salud es relevante para una mejor apreciación de sus necesidades y enfrentar de mejor forma la programación de la atención sanitaria de esta población que busca en Chile un lugar de acogida y mayor bienestar. Para profundizar los esfuerzos de integración en trabajo, salud, educación y en la comunidad parece aconsejable actualizar la legislación referente a migraciones, tal que permita abordar los problemas actuales a través de una ley migratoria que data de 1975.

Measuring a cosmological distance-redshift relationship using only gravitational wave observations of binary neutron star coalescences.

Detection of gravitational waves from the inspiral phase of binary neutron star coalescence will allow us to measure the effects of the tidal coupling in such systems. Tidal effects provide additional contributions to the phase evolution of the gravitational wave signal that break a degeneracy between the system's mass parameters and redshift and thereby allow the simultaneous measurement of both the effective distance and the redshift for individual sources. Using the population of O(10(3)-10(7)) detectable binary neutron star systems predicted for 3rd generation gravitational wave detectors, the luminosity distance-redshift relation can be probed independently of the cosmological distance ladder and independently of electromagnetic observations. We conclude that for a range of representative neutron star equations of state the redshift of such systems can be determined to an accuracy of 8%-40% for z<1 and 9%-65% for 1

Pulsar discovery by global volunteer computing.

Einstein@Home aggregates the computer power of hundreds of thousands of volunteers from 192 countries to mine large data sets. It has now found a 40.8-hertz isolated pulsar in radio survey data from the Arecibo Observatory taken in February 2007. Additional timing observations indicate that this pulsar is likely a disrupted recycled pulsar. PSR J2007+2722's pulse profile is remarkably wide with emission over almost the entire spin period; the pulsar likely has closely aligned magnetic and spin axes. The massive computing power provided by volunteers should enable many more such discoveries.

Proteína C reactiva como predictor de complicaciones postoperatorias en apendicitis aguda / C reactive protein predicting post operative complications in acute appendicitis

La apendicitis aguda es una patología frecuente. Sus complicaciones se relacionan con una estadía hospitalaria prolongada y mayor gasto de recursos, por lo que nos parece relevante buscar índices predictivos de estas complicaciones para poder así establecer medidas preventivas que permitan economizar recursos y acortar la estadía postoperatoria de estos pacientes. Objetivo: Determinar si existió alguna relación entre valores anormales de PCR al ingreso y el desarrollo de complicaciones locales postoperatorias. Material y Método: Estudio descriptivo retrospectivo de una muestra aleatoria de 197 pacientes, operados de apendicitis aguda confirmadas histológicamente, entre el 01-01-1998 y el 31-12-2000 en el Hospital Las Higueras de Talcahuano, relacionando el valor de la PCR al ingreso (normal < 1 mg/I) con la aparición de complicaciones infecciosas locales postoperatoria (infección herida operatoria y/o absceso residual). Resultados: Se encontró un 14,3 por ciento de pacientes con PCR normales de los cuales ninguno presentó complicaciones postoperatorias. Un 85,7 por ciento de los pacientes presentó PCR elevada de los que un 16,6 por ciento presentó complicaciones infecciosas locales en el postoperatorio. Conclusión: Se observó una relación estadísticamente significativa (p < 0,005) entre valores elevados de PCR al ingreso, con la incidencia de complicaciones infecciosas locales postoperatorias.

The effects of anxiety sensitivity and history of panic on reactions to stressors in a non-clinical sample.

This study attempted to determine the effects of physical and mental stressors on a non-clinical population that varied in terms of history of panic attacks and level of anxiety sensitivity. Groups included: (1) individuals with a history of panic attacks, (2) those with high scores on the anxiety sensitivity index and no history of panic and (3) those with no panic experiences and low anxiety sensitivity. Results indicated that participants with a history of panic and those with high anxiety sensitivity reported significantly higher levels of anxiety ratings, bodily symptoms, and anxious thoughts than low anxiety sensitivity subjects during a balloon inflation task. Groups did not differ on any of the dependent measures of stress during a mental arithmetic task. Results indicate that anxiety sensitivity is predictive of whether individuals are likely to panic in response to challenges that induce uncomfortable somatic sensations.
