Presión arterial en preescolares de la localidad de Usaquén en Bogotá

Introducción: La hipertensión arterial es un problema de salud pública tanto en países industrializados como en vía de desarrollo. Su prevalencia en la infancia viene en aumento por lo que es relevante determinarla en niños preescolares a nivel local. Objetivo: Determinar la prevalencia de hipertensión arterial en niños de tres a cinco años de una cohorte de 14 hogares infantiles del ICBF de la localidad de Usaquén en Bogotá. Materiales y métodos: Se realizó un estudio de corte transversal analítico, utilizando la base de datos de un ensayo aleatorizado y controlado del año 200913, y se evaluaron las cifras de tensión arterial de acuerdo a sexo, edad, talla y su correlación con el IMC con un nivel de confianza del 95% y precisión del 1%. Se calcularon las medias, desviaciones estándar, percentiles y prevalencia. Resultados: Se obtuvo una muestra de 1035 casos, encontrándose una prevalencia de 4,5% de HTA sistólica, 10,4% de diastólica, ambas en estadio I; teniendo en cuenta tanto sistólica como diastólica, fue de 11,6% en estadio I. Se determinaron los valores de presión arterial sistólica y diastólica en cuartiles de acuerdo a edad, sexo y talla. El coeficiente de correlación entre el IMC y los niveles de presión arterial sistólica y diastólica fueron de 0.0992 y 0.0362 respectivamente. Conclusión: La prevalencia de HTA general fue de 11,6%, predominando la diastólica en estadio I en niños preescolares. No se encontró correlación entre el IMC y las cifras de tensión arterial sistólica y diastólica.

Guerra e identidade: um estudo da marcialidade no Heimskringla

The goal of our dissertation is to study how the Scandinavian writings produced a Norwegian identity of warlike ideals in a compilation of Icelandic sagas known as Heimskringla and has parts of its content focused on storytelling about a troubled time of Scandinavian monarchies rising between the 8th and 11th centuries, which is called the Viking Age. The Heimskringla, also known as The Circle of the World is a set of writings based on Icelandic oral memory about the Norwegian kings and the conception of a Norwegian territory. While we investigated the relationship between the members of royalty, their companions and the Scandinavian people, we delineate the relationship between memory, identity and war. Our study points out how the Scandinavian war produces, in its storytelling, proper spaces, in socio-political relations among the participants, in the organization of its conflicts or the location of war activities, where places are transformed into essential points in these narratives. The war is both a place of identity statements and a space of practices, necessary for the strengthening of royal power

Mangia, bevi, ama. Cibo e rituali alimentari del matrimonio nell'Occidente altomedievale

La ricerca pone al centro dell’indagine lo studio dell’importanza del cibo nelle cerimonie nuziali dell’Europa occidentale nei secoli V-XI. Il corpus di fonti utilizzate comprende testi di genere diverso: cronache, annali, agiografie, testi legislativi, a cui si è aggiunta un’approfondita analisi delle antiche saghe islandesi. Dopo un'introduzione dedicata in particolare alla questione della pubblicità della celebrazione, la ricerca si muove verso lo studio del matrimonio come “processo” sulla base della ritualità alimentare: i brindisi e i banchetti con cui si sigla l’accordo di fidanzamento e i ripetuti convivi allestiti per celebrare le nozze. Si pone attenzione anche ad alcuni aspetti trasversali, come lo studio del caso della “letteratura del fidanzamento bevuto”, ossia una tradizione di testi letterari in cui il fidanzamento tra i protagonisti viene sempre ratificato con un brindisi; a questo si aggiunge un’analisi di stampo antropologico della "cultura dell’eccesso", tipica dei rituali alimentari nuziali nel Medioevo, in contrasto con la contemporanea "cultura del risparmio". L'analisi si concentra anche sulle reiterate proibizioni al clero, da parte della Chiesa, di partecipare a banchetti e feste nuziali, tratto comune di tutta l’epoca altomedievale. Infine, la parte conclusiva della ricerca è incentrata sulla ricezione altomedievale di due figure bibliche che pongono al centro della narrazione un banchetto nuziale: la parabola delle nozze e il banchetto di Cana. L’insistente presenza di questi due brani nelle parole dei commentatori biblici mostra la straordinaria efficacia del “linguaggio alimentare”, ossia di un codice linguistico basato sul cibo (e su contesti quali l’agricoltura, la pesca, ecc.) come strumento di comunicazione sociale di massa con una valenza antropologica essenzialmente universale.

El Cantar de Mio Cid y el contexto europeo

El artículo establece un conjunto de comparaciones entre aspectos narrativos y temáticos del Cantar de Mio Cid y composiciones literarias del contexto cultural europeo, desde epopeyas bizantinas y turcas, o Sagas islandesas, hasta el Beowulf y la épica de Irlanda. Se analizan concepciones cercanas del heroísmo épico medieval que contribuyen a caracterizarlo diferenciadamente de sus congéneres antiguos.

(Supplement 1) Selected chemical composition of Icelandic river waters and bedrock age

In this study we map the spatial distribution of selected dissolved constituents in Icelandic river waters using GIS methods to study and interpret the connection between river chemistry, bedrock, hydrology, vegetation and aquatic ecology. Five parameters were selected: alkalinity, SiO2, Mo, F and the dissolved inorganic nitrogen and dissolved inorganic phosphorus mole ratio (DIN/DIP). The highest concentrations were found in rivers draining young rocks within the volcanic rift zone and especially those draining active central volcanoes. However, several catchments on the margins of the rift zone also had high values for these parameters, due to geothermal influence or wetlands within their catchment area. The DIN/DIP mole ratio was higher than 16 in rivers draining old rocks, but lowest in rivers within the volcanic rift zone. Thus primary production in the rivers is limited by fixed dissolved nitrogen within the rift zone, but dissolved phosphorus in the old Tertiary catchments. Nitrogen fixation within the rift zone can be enhanced by high dissolved molybdenum concentrations in the vicinity of volcanoes. The river catchments in this study were subdivided into several hydrological categories. Importantly, the variation in the hydrology of the catchments cannot alone explain the variation in dissolved constituents. The presence or absence of central volcanoes, young reactive rocks, geothermal systems and wetlands is important for the chemistry of the river waters. We used too many categories within several of the river catchments to be able to determine a statistically significant connection between the chem¬istry of the river waters and the hydrological categories. More data are needed from rivers draining one single hydrological category. The spatial dissolved constituent distribution clearly revealed the difference between the two extremes, the young rocks of the volcanic rift zone and the old Tertiary terrain.

Synaptic Rearrangement Following Axonal Injury: Old And New Players.

Following axotomy, the contact between motoneurons and muscle fibers is disrupted, triggering a retrograde reaction at the neuron cell body within the spinal cord. Together with chromatolysis, a hallmark of such response to injury is the elimination of presynaptic terminals apposing to the soma and proximal dendrites of the injured neuron. Excitatory inputs are preferentially eliminated, leaving the cells under an inhibitory influence during the repair process. This is particularly important to avoid glutamate excitotoxicity. Such shift from transmission to a regeneration state is also reflected by deep metabolic changes, seen by the regulation of several genes related to cell survival and axonal growth. It is unclear, however, how exactly synaptic stripping occurs, but there is substantial evidence that glial cells play an active role in this process. In one hand, immune molecules, such as the major histocompatibility complex (MHC) class I, members of the complement family and Toll-like receptors are actively involved in the elimination/reapposition of presynaptic boutons. On the other hand, plastic changes that involve sprouting might be negatively regulated by extracellular matrix proteins such as Nogo-A, MAG and scar-related chondroitin sulfate proteoglycans. Also, neurotrophins, stem cells, physical exercise and several drugs seem to improve synaptic stability, leading to functional recovery after lesion.
