Diez mandamientos fisiológicos a lograr durante el traumatismo craneoencefálico grave
2021
Resumen Los avances en la monitorizacion cerebral multiparametrica han permitido ahondar en el conocimiento de la fisiopatologia del traumatismo craneoencefalico, y en como la terapeutica disponible puede modularla. Para ello, se antoja imprescindible conocer e interpretar una serie de principios fisiologicos y fisiopatologicos basicos que propician, por un lado, un entorno metabolico cerebral adecuado para prevenir un incremento de la lesion cerebral primaria y favorecer su recuperacion, y por otro lado, permiten adaptar de forma individualizada los recursos terapeuticos a la situacion concreta del paciente. En el presente articulo se exponen, en forma de decalogo, sustentados en dichas no…
Rendimiento de las pruebas complementarias en el estudio de pacientes con dolor abdominal crónico
2021
Resumen: Introducción: El dolor abdominal crónico (DAC) en la infancia es un motivo de consulta frecuente que afecta a la vida familiar, y en ocasiones precisa realización de pruebas complementarias. El objetivo fue realizar el análisis cualitativo, cuantitativo y económico de las pruebas que se solicitan. Pacientes y métodos: Estudio observacional, prospectivo y multicéntrico, incluyendo pacientes entre 4-15 años con DAC. Se diferenciaron 2 grupos: orgánico y funcional. Se recogieron las siguientes variables: clínicas, pruebas complementarias y su coste. Resultados: Se incluyeron 235 niños con DAC (edad media 9,7 ± 2,7 años). Un 79% resultaron trastornos funcionales y un 21% orgánicos. Cas…

Comments on "Dental lessons from past to present: Ultrastructure and composition of teeth from plesiosaurs, dinosaurs, extinct and recent sharks" by …
2016
The paper mentioned in the title suggests that several groups of extinct vertebrates used fluoroapatite as a tooth mineral in dentine and enamel when alive; its authors posit that this tooth mineralization drastically changed in all these lineages at some point during their evolution, leading to the use of hydroxyapatite as an alternative primary tooth mineral, because of hitherto unconsidered environmental changes. These conclusions are based on their finding high fluoride levels (i.e. fluoroapatite) in the dentine of fossilised shark teeth as well as in both the dentine and enamel of plesiosaurs, mosasaurs, and dinosaurs, which is in sharp contrast to recent teeth (which contain almost no…
Dos terapias conocidas podrían ser efectivas como adyuvantes en el paciente crítico infectado por COVID-19
2020
Resumen La neumonia causada por coronavirus, que se origino en Wuhan, China, a finales de 2019, se ha extendido por todo el mundo convirtiendose en una pandemia. Desafortunadamente, a dia de hoy no existe ninguna vacuna especifica para el virus COVID-19, y el tratamiento esta siendo de soporte con anadido de antivirales y otros farmacos, sin que hasta la fecha se haya evidenciado un beneficio claro. Muchos de estos pacientes se deterioran rapidamente y requieren ser intubados y ventilados mecanicamente, lo que esta provocando el colapso del sistema sanitario en muchos paises debido a la falta de ventiladores y de camas de criticos. En este documento revisamos dos terapias adyuvantes sencill…
Combining GPU and FPGA technology for efficient exhaustive interaction analysis in GWAS
2016
Interaction between genes has become a major topic in quantitative genetics. It is believed that these interactions play a significant role in genetic variations causing complex diseases. Due to the number of tests required for an exhaustive search in genome-wide association studies (GWAS), a large amount of computational power is required. In this paper, we present a hybrid architecture consisting of tightly interconnected CPUs, GPUs and FPGAs and a fine-tuned software suite to outperform other implementations in pairwise interaction analysis while consuming less than 300Watts and fitting into a standard desktop computer case.
Shear bond strength and debonding characteristics of metal and ceramic brackets bonded with conventional acid-etch and self-etch primer systems: an i…
2016
Background: Different in-vitro studies have reported various results regarding shear bond strength (SBS) of orthodontic brackets when SEP technique is compared to conventional system. This in-vivo study was designed to compare the effect of conventional acid-etching and self-etching primer adhesive (SEP) systems on SBS and debonding characteristics of metal and ceramic orthodontic brackets. Material and Methods: 120 intact first maxillary and mandibular premolars of 30 orthodontic patients were selected and bonded with metal and ceramic brackets using conventional acid-etch or self-etch primer system. The bonded brackets were incorporated into the wire during the study period to simulate th…
Effect of in-office bleaching gels with calcium or fluoride on color, roughness, and enamel microhardness
2019
Background Commercial bleaching gels with remineralizing agents were developed to reduce the adverse effects of dental bleaching. The present study evaluated the effects on teeth of in-office bleaching gels containing 35-40% hydrogen peroxide (HP) with Calcium (Ca) or Fluoride (F). Material and methods Bovine enamel/dentin blocks (4x4x2.5 mm) were randomly divided into the following groups (n=12): no treatment (control); 35% HP (Whiteness HP, FGM); 35% HP with Ca (Whiteness HP Blue, FGM); 40% HP with F (Opalescence Boost, Ultradent). The specimens were analyzed for color (ΔL*, Δa*, Δb*, and ΔE), roughness (Ra), and Knoop microhardness (KHN). The color and KHN data were submitted to ANOVA an…
