Abstract: introduction: haemodialysis (hd) lines are traditionally primed with sodium heparin and saline solution, which entails the haemorrhagic risk associated to the passing of heparin into the blood. aim: to compare hd dialyser priming with and without sodium heparin, in terms of coagulation, dialytic efficacy, and economic efficacy. material and method: a randomized, prospective studio of 3482 sessions with 109 hd patients (x 66.8±15 years, 40% women, 44% diabetic, 45% with high-flow tunnelled catheter, 50% native iaf, 5% prosthetic iaf). 1827 sessions carried out with fifty-nine patients were included in the control group (primed with saline solution + sodium heparin) and 1455 sessions with patients in the study group (primed with saline solution). the monitoring period was 5 months. variables related to the coagulation of the circuit and the efficacy of the dialysis were analysed: selected blood flow (qb) and effective qb, final status of the dialyser, number of changes of dialyser, number of changes of the arterial line, number of changes of the venous, average kt/hour measured by ionic dialysance and heparinization of the circuit. the efficacy in economic terms was also studied. results: there are no significant differences in the results related to coagulation and efficacy of the dialysis obtained in both groups, except x of heparin with low molecular weight (2476±1089 iu in the study group compared to 2854±1414 iu in the control group). priming without heparin represents a saving of 0.50 € per session. conclusions: priming with saline solution does not affect the hd dose, and does not entail a greater risk of coagulation of the system compared to a priming solution to which heparin has been added, avoids the risk of heparin passing into the bloodstream, reduces handling in the connection protocols and reduces costs.

Abstract: the term "interculturality" refers to the communicative interaction that takes place between two or more groups of people from different cultures. the present paper examines the interaction between the western culture and the mapuche culture; the relationship between modernity and ancestral traditions. the purpose was to describe, from an intercultural perspective, the current knowledge, attitudes and practices concerning mapuche traditional food in the educational community of the provincial school no. 89 in epuyén, chubut province, argentina. a qualitative, descriptive, transversal study was conduced. the participants were 67 fourth-fifth-sixth grade mapuche and non-mapuche children, 12 mothers, 2 managers, 3 teachers and 3 others, all intentionally selected. data on knowledge, attitudes, practices and methods of transmission concerning traditional mapuche food were obtained by combining techniques: participant observation, focus groups, semi structured interviews and educational activities. the analysis and data processing were determined by the method of constant comparison, until obtaining theoretical saturation. the main features of the school are cultural mapuche and non- mapuche heterogeneity in the same place, and a non- intercultural education system. in the education community, what is seen is a feeling of not belonging to the ethnicity, abandonment of a breeding, educational and organizational model, differences in knowledge, practices and transmission of a traditional food know-how. despite this, the identity endures and finds support in their last bastion: last names. this heterogeneous reality is homogenized by reactivating, recovering, revaluing and protecting the ancestral mapuche food as a means of reaffirmating an identity that was silenced for so many years. beyond the official program of education, the vision and institutional attitudes promote interculturalism. in this way, the school is an appropriate place to implement these actions.

Abstract: Al decir interculturalidad se hace referencia a la interacción comunicativa que se produce entre dos o más grupos humanos de diferentes culturas. En el presente trabajo se ahonda sobre la interacción entre cultura occidental y cultura mapuche, a la articulación entre modernidad y tradiciones ancestrales. El propósito fue describir desde una perspectiva intercultural los conocimientos, actitudes y prácticas actuales sobre alimentación tradicional mapuche, en la Comunidad educativa de la Escuela Provincial No 89 de Epuyén, Provincia de Chubut, Argentina. Se realizó un estudio cualitativo, descriptivo, transversal. Participaron 67 ni os/as mapuche y no mapuche de cuarto, quinto y sexto grado, 12 madres, 2 directivos, 3 docentes y 3 no docentes, seleccionados todos de manera intencional. Los datos sobre conocimientos, actitudes, prácticas y modos de transmisión respecto a la alimentación tradicional mapuche se obtuvieron mediante la combinación de técnicas: observación participante, grupos focales, entrevistas semiestructuradas y actividades didácticas. El análisis y tratamiento de datos se determinó por el método de comparación constante, hasta obtener saturación teórica. La heterogeneidad cultural, mapuche y no mapuche en un mismo espacio, y un sistema educativo no intercultural son las principales características de la escuela. En la comunidad educativa se evidencia el sentimiento de no pertenencia a la etnia; abandono del modelo de crianza, educativo y organizacional; diferencias de conocimientos, prácticas y transmisión del saber-hacer alimentario tradicional. A pesar de esto, la identidad perdura y se apoya en su último bastión para reelaborarse: los apellidos. Esta realidad heterogénea se homogeniza en las actitudes de reactivación, recuperación, revalorización y protección de la alimentación ancestral mapuche, como reafirmación de una identidad que por tantos a os fue acallada. La visión y las actitudes institucionales, más allá del programa oficial educativo, promueven la interculturalidad. Así, la escuela es un espacio oportuno para implementar dichas acciones.

Abstract: Introducción: la morbilidad materna extremadamente grave es la complicación grave que ocurre durante el embarazo, el parto y/o el puerperio, que pone en riesgo la vida de la mujer y requiere de una atención inmediata con el fin de evitar la muerte. Objetivo: caracterizar la morbilidad materna extremadamente grave en La Habana, Camagüey y Santiago de Cuba. Métodos: se realizó un estudio transversal, desde enero hasta diciembre del a o 2009. El universo de estudio estuvo constituido por todas las gestantes que se diagnosticaron como morbilidad materna extremadamente grave en hospitales maternos, según criterios de inclusión. La información se obtuvo, una vez realizado el diagnóstico en los hospitales maternos, a través de la historia clínica de cada gestante en la atención hospitalaria y durante su atención prenatal. Resultados: fueron diagnosticadas 222 pacientes. Los riesgos preconcepcionales con mayor frecuencia fueron la malnutrición, 55 (29,3 %), a expensa fundamentalmente de la obesidad (67,3 %); la edad extrema (24,5 %) y la multiparidad (22,5 %). La hipertensión arterial 70 (37,2 %) y la preeclampsia-eclampsia 79 (42,2 %) se identificaron dentro de los riesgos maternos y perinatales. El 39,2 % de las gestantes presentaron complicaciones después del parto. Las mayores cifras de morbilidad fueron, según manejo instaurado, por transfusión y Unidad de Cuidados Intensivos (50 %); por cirugía se reportó el 49,5 %, mientras que en los dos grupos restantes se presentó el shock hipovolémico con el 31,5 %. Conclusiones: la morbilidad materna extremadamente grave ocurre con mayor frecuencia después del parto y sus principales causas están relacionadas con la pérdida masiva de sangre. Introduction: extremely serious maternal morbidity (MMEG) is a serious complication that occurs during pregnancy, childbirth and / or postpartum threatening the lives of women and requires immediate attention to prevent death. Objective: characterization of extremely severe maternal morbidity in Havana, Camagüey, and Santiago de Cuba. Methods: a cross-sectional study was conducted from January to December 2009. The universe consisted of all pregnant women who were diagnosed as extremely serious maternal morbidity in maternity hospitals, according to the inclusion criteria. The information was obtained once the diagnosis was given in maternity hospitals through the medical history of each pregnant woman in hospital and prenatal care. Results: 222 patients were diagnosed. The most common preconception risk of malnutrition in 55 (29.3 %), 67.3 % were mainly obese, extreme age (24.5

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.44048
Abstract: The coexistence of acquired hemophilia A with a secondary retropharyngeal hematoma is an extremely unusual condition with important clinical implications. The purpose of this paper is to present a case involving a patient whose first clinical manifestation, namely dysphagia, along with specific clinical examination and imaging findings, led to an incorrect initial diagnosis of a retropharyngeal abscess. However, performance of a more thorough clinical examination led to the correct diagnosis of a hematoma secondary to acquired hemophilia A. This allowed surgery to be avoided in a patient at a high risk of bleeding. Conclusions: Acute neck masses require meticulous differential diagnosis assessing the possible presence of various causative systemic diseases before the most appropriate therapy can be determined.

Abstract:

This paper shows the effects caused by the combination of two factors: an anthropic factor and one natural. The leading causes of imbalance in the subsoil due to drawdown of the aquifer is reflected on the surface with the appearance of cracks on ground, then came the lateral and vertical movements called faulting. This geological phenomenon is due to a pattern of orientation is associated with a regional fault system, lateral movement is almost imperceptible but the vertical displacement becomes important because it is the most conspicuous and be responsible for the damage caused to the urban infrastructure, vertical faulting is related to the drawdown generated by intense extraction of groundwater. The demand for groundwater, increasing year by year in the past four decades because of the change in land use, the most significant change was the shift from rain feed crop to irrigated crop agriculture, this change in land use occurred on Celaya’s Valley between year period 1976-2009 was quantified by use of remote sensing and geographic information systems (GIS).

Abstract: Se comprobaron las modificaciones de la somatometría posnatal temprana en crías de rata con crecimiento intrauterino retardado comparándolas con un grupo control. Se indujo el crecimiento intrauterino retardado, por ligadura de la arteria uterina en ambos cuernos en el día 16 de la gestación, en ratas de la línea Sprague Dawley, a las crías de ambos grupos, divididas en 4 subgrupos, se le tomó peso, talla y diámetros craneanos al nacimiento, 7, 14 y 21 d. Los resultados mostraron una disminución severa de peso, talla y diámetros craneanos al nacimiento en los fetos del grupo experimental. El peso se recuperó a los 14 d mientras que la talla y los diámetros craneanos no. Se observó que la disminución del flujo sanguíneo en la última semana de gestación produjo en las crías estudiadas alteraciones somatométricas que se mantienen hasta el destete. The modifications of early postnatal somatometry were proved in offsprings of rats with intrauterine growth retardation, comparing them with a control group. The intrauterine growth retardation was induced by ligation of the uterine artery in both horns on the 16th day of gestation in Sprague Dawley rats. The offsprings of both groups were divided into 4 subgroups. The weight, height and cranial diameters were measured at birth, 7, 14 and 21 days. The results showed a severe reduction of weight, height and cranial diameters at birth in the fetuses of the experimental group. The weight was recovered 14 days later, but the height and cranial diameters were not. It was observed that the decrease of blood flow in the last week of gestation caused somatosometric alterations in the studied offsprings that are maintained until weaning.
