The outcome of spinal surgery in dogs with absent voluntary motor function and nociception following intervertebral disc (IVD) herniation is highly variable, which likely attests to differences in the severity of spinal cord damage. This retrospective study evaluated the extent to which neurological signs correlated with histologically detected spinal cord damage in 60 dogs that were euthanased because of thoracolumbar IVD herniation. Clinical neurological grades correlated significantly with the extent of white matter damage (P<0.001). However, loss of nociception also occurred in 6/31 (19%) dogs with relatively mild histological changes. The duration of clinical signs, Schiff-Sherrington posture, loss of reflexes and pain on spinal palpation were not significantly associated with the severity of spinal cord damage. Although clinical-pathological correlation was generally good, some clinical signs frequently thought to indicate severe cord injury did not always correlate with the degree of cord damage, suggesting functional rather than structural impairment in some cases.

Wer anderen Gutes tun möchte, benötigt die Möglichkeit, wirksam tätig zu werden. Dabei kann es um Wissen um Therapietechniken und -verfahren gehen, um die Kenntnis derjenigen, die man fragen oder konsultieren sollte, aber natürlich auch um finanzielle Mittel, um etwa Spezialisten, ihre Kompetenzen und technologischen Möglichkeiten nutzen zu können. Man kann diese kulturellen, sozialen und ökonomischen Ressourcen mit dem französischen Soziologen Pierre Bourdieu unter dem Begriff des Kapitals zusammenfassen: Kulturelles, soziales und ökonomisches Kapital bezeichnen dann jeweils einen spezifischen Typ von sozialer Gestaltungsmacht. Aber gerade im Gesundheitswesen ist die Frage nach Gestaltungsmacht heikel. Denn einerseits fühlt sich jemand, der unter einer akuten und vielleicht sogar schmerzhaften Krankheit leidet, oft ohnehin schon verletzlich, ohnmächtig und ausgeliefert, sodass die Frage nach der Macht hier unangebracht oder obsolet erscheint. Andererseits wirkt in einem Bereich, in dem es um Fürsorge (caring), um Wohltun (beneficence), Behandlung und Heilung geht, der Begriff der Macht, den wir oft genug mit Herrschaft und Gewalt verbinden, merkwürdig fehl am Platz. Klassisch wird die Frage nach der Macht im Bereich des Gesundheitswesens unter dem Etikett des Paternalismus verhandelt und vor allem auf das Verhältnis von Arzt und Patient bezogen, in dem dann das normative Benevolenzprinzip und das Prinzips des Respekts vor der Autonomie des Patienten oder der Patientin in Konflikt geraten können. Allerdings lässt sich fragen, ob diese Perspektive nicht eine Engführung darstellt. Denn oft sind nicht nur die unmittelbar kranken oder pflegebedürftigen Patienten und Patientinnen, sondern auch ihre Angehörigen betroffen – bei betagten Patienten ist das sogar die Regel. Zudem sorgt die zunehmende Bedeutung, Präsenz und nicht zuletzt Verwissenschaftlichung der Pflege für möglichen Konfliktstoff zwischen Pflegenden und Behandelnden. Und schliesslich führt der steigende ökonomische Druck zu Reibungsflächen zwischen den zu Effizienz und ökonomischer Nachhaltigkeit verpflichteten Verwaltenden und Behandelnden wie Pflegenden. Der Band, der Beiträge einer interdisziplinären Berner Tagung aufnimmt und durch zusätzliche Perspektiven ergänzt, geht der ‹Macht der Fürsorge› und ihrer Verteilung im Sechseck von Patienten und Patientinnen, Behandelnden, Pflegenden, Verwaltenden, Angehörigen und politisch Verant-wortlichen in ethischer Perspektive nach.

Comets contain the best-preserved material from the beginning of our planetary system. Their nuclei and comae composition reveal clues about physical and chemical conditions during the early solar system when comets formed. ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) onboard the Rosetta spacecraft has measured the coma composition of comet 67P/Churyumov-Gerasimenko with well-sampled time resolution per rotation. Measurements were made over many comet rotation periods and a wide range of latitudes. These measurements show large fluctuations in composition in a heterogeneous coma that has diurnal and possibly seasonal variations in the major outgassing species: water, carbon monoxide, and carbon dioxide. These results indicate a complex coma-nucleus relationship where seasonal variations may be driven by temperature differences just below the comet surface.

Recently, the ROSINA mass spectrometer suite on board the European Space Agency's Rosetta spacecraft discovered an abundant amount of molecular oxygen, O2, in the coma of Jupiter family comet 67P/Churyumov-Gerasimenko of O2/H2O = 3.80 ± 0.85%. It could be shown that O2 is indeed a parent species and that the derived abundances point to a primordial origin. Crucial questions are whether the O2 abundance is peculiar to comet 67P/Churyumov-Gerasimenko or Jupiter family comets in general, and also whether Oort cloud comets such as comet 1P/Halley contain similar amounts of molecular oxygen. We investigated mass spectra obtained by the Neutral Mass Spectrometer instrument during the flyby by the European Space Agency's Giotto probe of comet 1P/Halley. Our investigation indicates that a production rate of O2 of 3.7 ± 1.7% with respect to water is indeed compatible with the obtained Halley data and therefore that O2 might be a rather common and abundant parent species.

Grand Canonical Monte Carlo simulations are used to reproduce the N₂/CO ratio ranging between 1.7 x 10⁻³ and 1.6 x 10⁻² observed in situ in the Jupiter-family comet 67 P/Churyumov-Gerasimenko (67 P) by the ROSINA mass spectrometer on board the Rosetta spacecraft. By assuming that this body has been agglomerated from clathrates in the protosolar nebula (PSN), simulations are developed using elaborated interatomic potentials for investigating the temperature dependence of the trapping within a multiple-guest clathrate formed from a gas mixture of CO and N₂ in proportions corresponding to those expected for the PSN. By assuming that 67 P agglomerated from clathrates, our calculations suggest the cometary grains must have been formed at temperatures ranging between ~ 31.8 and 69.9 K in the PSN to match the N₂/CO ratio measured by the ROSINA mass spectrometer. The presence of clathrates in Jupiter-family comets could then explain the potential N₂ depletion (factor of up to ~ 87 compared to the protosolar value) measured in 67 P/Churyumov-Gerasimenko.

Critical measurements for understanding accretion and the dust/gas ratio in the solar nebula, where planets were forming 4.5 billion years ago, are being obtained by the GIADA (Grain Impact Analyser and Dust Accumulator) experiment on the European Space Agency's Rosetta spacecraft orbiting comet 67P/Churyumov-Gerasimenko. Between 3.6 and 3.4 astronomical units inbound, GIADA and OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) detected 35 outflowing grains of mass 10(-10) to 10(-7) kilograms, and 48 grains of mass 10(-5) to 10(-2) kilograms, respectively. Combined with gas data from the MIRO (Microwave Instrument for the Rosetta Orbiter) and ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instruments, we find a dust/gas mass ratio of 4 +/- 2 averaged over the sunlit nucleus surface. A cloud of larger grains also encircles the nucleus in bound orbits from the previous perihelion. The largest orbiting clumps are meter-sized, confirming the dust/gas ratio of 3 inferred at perihelion from models of dust comae and trails.

Background. Health literacy is an important determinant for quality health care, and affects communication between patients and physicians. Poor communication may result in negative effects in health. Improved communication between patients and physicians could positively affect health outcomes. Communication skills are teachable.^ Objectives. (1) to evaluate the process involved in the design and implementation of a health literacy intervention targeting pediatric providers’ communication skills at the Texas Children’s Health Plan in Houston, Texas; and (2) to describe lessons learned from this process that may be used in future attempts to address the issue of health literacy and health communication. ^ Design/methods. The process evaluation of the implementation of a health literacy strategy at the Texas Children’s Health Plan (TCHP) consisted of a critical analysis of all documents and minutes from meetings of the team of investigators. It also involved a secondary analysis of data collected between December 2006 and June 2007. Descriptive statistics, paired t-test and Wilcoxon-signed-rank test were employed in analyzing the data. This information was complemented with a limited review of existing literature on communication skills training programs. ^ Results. The design of the educational intervention followed recommendations from experts in the field of health literacy. The delivery of the intervention was possible and benefited from existing resources and logistics within the TCHP. Very few targeted providers participated in two offerings of the workshop (6.6% and 1.7% respectively). After the educational intervention, providers showed increased knowledge of health literacy facts and its effects in health (p=0.001); increased awareness of the low health literacy problem (p=0.003); increased expectations for change in practice (p=0.002), and intent to use health literacy strategies for communication immediately following the intervention (p=0.001). Low participation indicated the need for further investigation of barriers to, and means for successful implementation of programs aimed to improving health communication. ^ Conclusions. A short, focused intervention utilizing health literacy strategies for communication appeared effective in increasing knowledge and intentions for change in a small group of pediatric providers. ^

La decisión de continuar con una gestación, o interrumpirla, no resulta sencilla para las mujeres. Pero cuando un embarazo pone en riesgo la vida, o puede causar problemas graves en la salud de las mujeres, ellas tienen el derecho a solicitar una interrupción legal del embarazo. Eso, en el Perú, se llama aborto terapéutico.

Recomendaciones para la implementación del plan regional de salud en la región de La Libertad en las prioridades sanitarias de embarazo no deseado, aborto y violencia familiar que afectan a los/as adolescentes Definida por los organismos internacionales como el grupo humano que se encuentra entre 10 y 19 años, la adolescencia es un periodo vulnerable sujeto a cambios somáticos y psicológicos y expuesto a fuertes presiones sociales de su entorno. en la adolescencia, las personas buscan y definen su propia identidad y se autoafirman como individuos. sin embargo, existe una percepción estereotipada de los/las adolescentes como un grupo humano carente de reflexión, díscolo, hedonista y siempre abierto a cualquier experimentación. La adolescencia es vista como una etapa problemática, especialmente por la aparición de características sexuales secundarias, por el crecimiento emocional psicológico, social y mental.

During the cruises 3 and 15 of R.V. "Meteor", representatives of 7 families of benthic abyssal gastropods were collected. The prevalent group was the Turridae; the Naticidae are represented by 2 species, the remaining families by a single species each. A survey of the frequency and distribution of the species within the study area is given. A systematic part deals with the individual species in detail, including notes on taxonomy, material and distribution. Concerning the composition of the abyssal gastropod fauna of the present material, Neogastropoda are 4 times as many as Archaeogastropoda and 6 times as many as Mesogastropoda and Opisthobranchia. 89 % of all specimens are Neogastropoda. Usually deep-sea organisms have a non-pelagic development, but many of the Iberian deep-sea Turrids have a planktotrophic protoconch, that means a long pelagic larval period. Among the 19 species, 2 are cosmopolitan, 9 show a transatlantic distribution and 8 are confined to East-Atlantic basins.

We demonstrate that in situ optical surface plasmon resonance spectroscopy can be used to monitor hybridization kinetics for unlabeled DNA in tethered monolayer nucleic acid films on gold in the presence of an applied electrostatic field. The dc field can enhance or retard hybridization and can also denature surface-immobilized DNA duplexes. Discrimination between matched and mismatched hybrids is achieved by simple adjustment of the electrode potential. Although the electric field at the interface is extremely large, the tethered single-stranded DNA thiol probes remain bound and can be reused for subsequent hybridization reactions without loss of efficiency. Only capacitive charging currents are drawn; redox reactions are avoided by maintaining the gold electrode potential within the ideally polarizable region. Because of potential-induced changes in the shape of the surface plasmon resonance curve, we account for the full curve rather than simply the shift in the resonance minimum.
