Introducción: La preeclampsia/eclampsia es una enfermedad del embarazo que puede producir cambios en el estado emocional de la mujer por su prolongado ingreso hospitalario. Objetivo: Conocer las experiencias vividas por las mujeres con preeclampsia/eclampsia durante el ingreso hospitalario. Los objetivos que se tendrán en cuenta serán conocer cómo se modifica el rol propio dentro de la organización familiar, conocer cómo impacta su ingreso respecto a suestado emocional, conocer cómo les afecta la estructura de la unidad a su estado emocional y conocer qué necesidades y/o cuidados terapéuticos reciben respeto al equipo sanitario. Ámbito: El estudio se realizará en el Hospital de la Vall d’ Hebrón de Barcelona. Metodología: Estudio fenomenológico. La muestra se escogerá intencionadamente que cumplirá con los criterios de inclusión (mujeres ingresadas por preeclampsia/eclampsia en launidad de materno infantil de la Vall d’ Hebrón de Barcelona), y se terminará hasta llegar al nivel de saturación teórico. Los datos se recogerán a través de entrevistas semi-estructuradas y de la observación participante. Consideraciones finales: Dada la baja incidencia que existe tanto a nivel nacional como internacional en estudios de este tipo, un estudio cualitativo que ayude a conocer las experiencias de las mujeres ingresadas por preeclampsia podría ayudar a mejorar la calidad y práctica asistencial enfermera.

High pressure induced changes on sarcoplasmic protein fraction and quality indicators

The combined effect of pressure and mild temperature treatments on bovine sarcoplasmic proteins and quality parameters was assessed. M. longissimus dorsi samples were pressurised in a range of 200–600 MPa and 10–30 °C. High Pressure Processing (HPP) induced a reduction of protein solubility (p < 0.001) compared to non-treated controls (NT), more pronounced above 200 MPa. HPP at pressures higher than 200 MPa induced a strong modification (p < 0.001) of meat colour and a reduction of water holding capacity (WHC). SDS–PAGE analysis demonstrated that HPP significantly modified the composition of the sarcoplasmic protein fraction. The pressurisation temperature mainly affected protein solubility and colour; a smaller effect was observed on protein profiles. Significant correlations (p < 0.001) between sarcoplasmic protein solubility and both expressible moisture (r = −0.78) and colour parameters (r = −0.81 to −0.91) suggest that pressure induced denaturation of sarcoplasmic proteins could influence to some extent WHC and colour modifications of beef. Changes in protein band intensities were also significantly correlated with protein solubility, meat lightness and expressible moisture. These results describe the changes induced by HPP on sarcoplasmic proteins and confirm a relationship between modification of the sarcoplasmic protein fraction and alteration of meat quality characteristics

Propuesta de programa de prevención de trastornos de la conducta alimentaria y la obesidad dirigido a profesores de educación física de secundaria

En la actual concepción bio-psico-social, los Trastornos del Comportamiento Alimentario (TCA) y la obesidad están plurideterminados por factores biológicos, psicológicos y socioculturales que actúan como elementos perpetuantes en el tiempo. Se pueden modificar actitudes contraproducentes con un programa de prevención multidisciplinar y disminuir de modo significativo la población con riesgo de obesidad y de padecer un TCA. Para ello, es necesario desarrollar dichos programas de prevención, previos a la atención primaria, y la estrategia para lograrlo es la intervención ante factores de riesgo, integrada en un conjunto de actividades de educación para la salud más global. Esta propuesta educativa pretende brindar a los profesores de Educación Física una revisión bibliográfica sobre la dimensión que desde la cultura occidental se tiene de los Trastornos del Comportamiento Alimentario (TCA) y la obesidad, al tiempo que promueve la reflexión sobre las posibilidades de intervención que ofrece la Educación Física desde el ámbito educativo en cuanto a la prevención de la obesidad, de los TCA, y de las conductas de riesgo. La presente propuesta de proyecto de prevención quiere destacar la función que cumplen docentes, tutores y tutoras, como acompañantes de los estudiantes, su posición privilegiada para conocerlos de cerca y estar así atentos a sus vivencias y la posibilidad de identificar oportunamente conductas no saludables en estudiantes que necesiten ciertas pautas para mejorar su estilo de vida, modificar sus habitos, o ser derivados para una atención especializada. Por ese motivo, en esta propuesta educativa se invita a los docentes y tutores a revisar sus convicciones personales y cuestionar la manera de pensar sobre la belleza física y el cuidado corporal. Esta reflexión junto a las pautas metodológicas permitirá abordar el tema de los TCA y la obesidad con tacto, respeto y la atención necesaria frente a los sentimientos de los y las estudiantes que se encuentran en un periodo de cambios importantes y con interrogantes en torno a su identidad e imagen corporal

La trampa de Rousseau. O com es pot saltar del convencionalisme al civisme

En aquest text es presenta una lectura de Rousseau des de la seva dimensió política i sota una perspectiva d’actualitat. Amb una aproximació a la concepció i l’argumentació dels elements que conformen el projecte polític en l’obra El contracte social —això és, justícia, moral i raó— les autores pensen a fons la modernitat des de l’assumpció del convencionalisme cívic liberal. L’espai públic és, doncs, l’eix que permet desgranar els arguments que condicionen un ésser humà que es desplega molt més enllà de la naturalesa i que donen sentit a una educació conscient d’una de les seves finalitats intrínseques més rellevants.

Les nou preguntes que Norbert Elias es va formular : debats, interrogants i pistes per a la sociologia del segle XXI

En aquest article dedicat a Norbert Elias en commemoració dels vint anys de la seva mort, proposem revisar, de manera resumida, la seva obra a partir dels interrogants ontològics, epistemològics i metodològics que Elias va encarar al llarg de la seva dilatada vida acadèmica i de recerca. L’article pretén ser, alhora, un punt i a part en el monogràfic, perquè en vol recollir alguns dels interrogants, debats i conclusions, com també tenir un paper introductori per a aquelles persones que, sense gaires coneixements previs sobre l’autor de Breslau, vulguin conèixer alguns dels trets definitoris de la seva trajectòria intel·lectual al llarg del segle XX. I, sobretot, quin llegat, en forma de grans preguntes, deixa per a la sociologia del segle XXI. L’article acaba amb una bibliografia escollida d’obres clau.

Two-step postmortem angiography with a modified heart-lung machine: preliminary results.

OBJECTIVE: The purpose of this study was to adapt and improve a minimally invasive two-step postmortem angiographic technique for use on human cadavers. Detailed mapping of the entire vascular system is almost impossible with conventional autopsy tools. The technique described should be valuable in the diagnosis of vascular abnormalities. MATERIALS AND METHODS: Postmortem perfusion with an oily liquid is established with a circulation machine. An oily contrast agent is introduced as a bolus injection, and radiographic imaging is performed. In this pilot study, the upper or lower extremities of four human cadavers were perfused. In two cases, the vascular system of a lower extremity was visualized with anterograde perfusion of the arteries. In the other two cases, in which the suspected cause of death was drug intoxication, the veins of an upper extremity were visualized with retrograde perfusion of the venous system. RESULTS: In each case, the vascular system was visualized up to the level of the small supplying and draining vessels. In three of the four cases, vascular abnormalities were found. In one instance, a venous injection mark engendered by the self-administration of drugs was rendered visible by exudation of the contrast agent. In the other two cases, occlusion of the arteries and veins was apparent. CONCLUSION: The method described is readily applicable to human cadavers. After establishment of postmortem perfusion with paraffin oil and injection of the oily contrast agent, the vascular system can be investigated in detail and vascular abnormalities rendered visible.

High pressure induced changes in beef muscle proteome: correlation with quality parameters

The relationship between pressure induced changes on individual proteins and selected quality parameters in bovine longissimus thoracis et lumborum (LTL) muscle was studied. Pressures ranging from 200 to 600 MPa at 20 °C were used. High pressure processing (HPP) at pressures above 200 MPa induced strong modifications of protein solubility, meat colour and water holding capacity (WHC). The protein profiles of non-treated and pressure treated meat were observed using two dimensional electrophoresis. Proteins showing significant differences in abundance among treatments were identified by mass spectrometry. Pressure levels above 200 MPa strongly modified bovine LTL proteome with main effects being insolubilisation of sarcoplasmic proteins and solubilisation of myofibrillar proteins. Sarcoplasmic proteins were more susceptible to HPP effects than myofibrillar. Individual protein changes were significantly correlated with protein solubility, L*, b* and WHC, providing further insights into the mechanistic processes underlying HPP influence on quality and providing the basis for the future development of protein markers to assess the quality of processed meats.

Evaluation of the SHRP Modified Georgia Digital Faultmeter, MLR-93-01, 1993

The SHRP Modified Georgia Digital Faultmeter was loaned to the Iowa Department of Transportation in January 1993 for evaluation. A study was undertaken comparing the faultmeter to Iowa's current method of fault measurement. The following conclusions were made after comparing the faultmeter to Iowa's gauge: The faultmeter was lighter and easier to maneuver and position. The faultmeter's direct readout was quicker to read. The faultmeter has increased precision. The faultmeter gave consistently lower fault readings than the Iowa gauge.

Fusion of the extended modified liquid drop model for nucleation and dynamical nucleation theory

We present a new phenomenological approach to nucleation, based on the combination of the extended modified liquid drop model and dynamical nucleation theory. The new model proposes a new cluster definition, which properly includes the effect of fluctuations, and it is consistent both thermodynamically and kinetically. The model is able to predict successfully the free energy of formation of the critical nucleus, using only macroscopic thermodynamic properties. It also accounts for the spinodal and provides excellent agreement with the result of recent simulations.

Entamoeba lysyl-tRNA synthetase contains a cytokine-like fomain with chemokine activity towards human endothelial cells

Immunological pressure encountered by protozoan parasites drives the selection of strategies to modulate or avoid the immune responses of their hosts. Here we show that the parasite Entamoeba histolytica has evolved a chemokine that mimics the sequence, structure, and function of the human cytokine HsEMAPII (Homo sapiens endothelial monocyte activating polypeptide II). This Entamoeba EMAPII-like polypeptide (EELP) is translated as a domain attached to two different aminoacyl-tRNA synthetases (aaRS) that are overexpressed when parasites are exposed to inflammatory signals. EELP is dispensable for the tRNA aminoacylation activity of the enzymes that harbor it, and it is cleaved from them by Entamoeba proteases to generate a standalone cytokine. Isolated EELP acts as a chemoattractant for human cells, but its cell specificity is different from that of HsEMAPII. We show that cell specificity differences between HsEMAPII and EELP can be swapped by site directed mutagenesis of only two residues in the cytokines' signal sequence. Thus, Entamoeba has evolved a functional mimic of an aaRS-associated human cytokine with modified cell specificity.

Outcome of a Modified Broström-Gould Procedure for Lateral Ankle Instability

Introduction: Ankle sprains affect 200'000 persons/year in Switzerland. Most incidences are successfully treated by conservative measures but 20% require reconstruction for symptomatic chronic lateral ankle instability. This study evaluates the functional outcome after a modified Broström-Gould technique as measured by different clinical scores and compares the functional outcome of this technique with other surgical treatments of ankle instability. Methods: This retrospective cohort study evaluates 47 patients who underwent a modified Broström-Gould procedure using suture anchors to refix the lateral ankle capsuloligamentary structures at our institution from 2005 to 2009 with a minimum follow-up of one year (13-72 Mo). All patients were operated by one single surgeon and evaluated by an independent examiner. The function was assessed using 4 scores including: the AOFAS (American Orthopaedic Foot and Ankle Society's Score) hindfoot score; the FAAM (Foot and Ankle Ability Measurement); the CAIT (Cumberland Ankle Instability Tool); the CAIS (Chronic Ankle Instability Scale). Results: Six patients were excluded leaving 41 patients for examination. 34 patients (83%) thought that their ankle was more stable after the surgery, 7 (17%) did not feel any difference. 27 patients were very satisfied, 11 satisfied and 3 not satisfied. Reasons for non satisfaction included persistent instability and pain. Ankle mobility returned to normal in 93% of patients. Five patients had transcient hypoesthesy in the area of the superficial peroneal nerve. One patient suffered from a superficial infection treated successfully by local measures. 80% had the perception of a normal ankle, 20% thought to be below normal. At follow-up the AOFAS was 89/100 (37-100), the FAAM 85/100% (35-100%), the CAIT 20/30 (5-30), and the CAIS 74/100% (27-100%). Conclusions: The modified Broström-Gould procedure, which belongs to the anatomic ankle stabilizations is relatively simple and offers good outcome that satisfied 93% of the patients in the present study. No active stabilisator is sacrificed. Preservation of the ankle mobility is better and the complication rate is lower than after non-anatomical procedures described in the literature. The CAIT appeared as the most severe score compared to the other scales used in our study.
