Grados altos en la Escala de Fisher predicen el desarrollo de hidrocefalia en pacientes con hemorragia subaracnoidea espontanea

Objetive. To determine if high grades of Fisher scale are useful to predict the development of hydrocephalus in consecutive Colombian patients with spontaneous subarachnoid hemorrhage (SAH) assessed from January 2005 to April 2012 with 12 month follow-up. Methods. 251 patients were included in a restrospective manner. The association between Fisher scale and hydrocephalus was analyzed bivariate and multivariate analysis. In addition, a systematic literature review (SLR) was done. Results. In our cohort of patients, the etiology of SAH was due to aneurysms; 78,5%. The prevalence of hydrocephalus was found to be of 27,1%. Overall survival with a 12 month follow-up was of 65,7%. Average age of included patients was 55,5 ± 15 years, and most of them were women; 65,7%. Having Fisher 4 and Hunt-Hess III are significantly associated with hydrocephalus: adjusted OR: 2.93 95% CI: 1.51-5.65, P <0.001, adjusted OR: 2.83 95% CI: 1.31-6.17 P=0.008 respectively. The SRL showed an overall prevalence of hydrocephalus between 17 and 68% and mortality varied between 3.0% and 33%. 50% of the included studies significantly associated intraventricular hemorrhage ( Fisher 4) with hydrocephalus. Conclusion. Our results confirm current concepts on post-SAH hydrocephalus and the fact that is obstructive and secondary to Fisher 4 and having neurological impairment on admission (Hunt and Hess III).

Escala de Fisher como factor predictor de hidrocefalia en hemorragia subaracnoidea espontanea

Objetivo. Determinar si la cantidad de sangre y su localización es el espacio subaracnoideo, medible con la escala de Fisher en las primeras 24 horas de ocurrido el ictus hemorrágico, es un factor predictor para el desarrollo de hidrocefalia en pacientes con diagnóstico de hemorragia subaracnoidea (HSA) espontánea, vistos en el Hospital Universitario Clínica San Rafael (HUCSR) con seguimiento de 12 meses. Métodos. 251 pacientes fueron incluidos en una cohorte retrospectiva. La asociación entre la escala de Fisher y el desarrollo de hidrocefalia en pacientes con HSA espontánea fue analizada a través de un análisis bivariado y multivariado. Resultados. La edad promedio de los pacientes fue de 55,5 ± 15 años; con predominancia en el sexo femenino 65,7%. La prevalencia de hidrocefalia fue de 27,1% en la cohorte y la etiología de la HSA fue en su mayoría por ruptura de aneurismas de arterias cerebrales; 78,5%. La sobrevida a 12 meses fue de 65,7%. Tanto el grado 4 en la escala de Fisher como Hunt-Hess III se asocian con el desarrollo de hidrocefalia: ORA; 2.93 IC 95%: 1.51-5.65, P <0.001, ORA 2.83 IC 95%: 1.31-6.17 P=0.008 respectivamente. Conclusión. La presencia de sangrado Intraventricular o intraparenquimatoso ( Fisher 4) en las primeras 24 horas, asociado a un deterioro neurológico al ingreso Hunt-Hess III están asociados con el desarrollo de hidrocefalia en los 251 pacientes evaluados con diagnóstico de HSA espontánea; hallazgos consistentes con lo reportado en la literatura mundial.

Diabetes relacionada a la fibrosis quística (DRFQ)

Importancia: el paciente con fibrosis quística después de las complicaciones gastrointestinales y pulmonares debe enfrentar otras comorbilidades como la diabetes relacionada a su condición . Dado el aumento en la esperanza de vida y el hecho de que virtualmente todas los pacientes con esta enfermedad pueden desarrollar alteración en el metabolismo de los carbohidratos, se requiere una sensibilización frente al tema que posibilite una detección temprana de esta entidad y un tratamiento óptimo que evite las complicaciones microvasculares e impacte entre otros el crecimiento pondo-estatural en pacientes en desarrollo y la función pulmonar. Objetivo : realizar una revisión actualizada de la literatura sobre la diabetes relacionada a la fibrosis quística, destacando las indicaciones de tamización y tratamiento. Conclusión : la FQ dentro de su abordaje requiere la detección temprana de la alteración del metabolismo de los carbohidratos con una prueba de tolerancia a la glucosa , el daño del islote pancreático , la disfunción inmune, la resistencia a la insulina, el estrés oxidativo entre otros elementos fisiopatológicos conllevan a un estado de depleción de insulina que producirán un efecto negativo microvascular así como a una reducción marcada de la función pulmonar, mayores tasa de infección e incremento de la mortalidad. La piedra angular del tratamiento en pacientes con o sin hiperglicemia es la insulina que mejora tanto el estado nutricional como la función pulmonar ; nuevos antidiabéticos orales con efecto incretinas y fármacos modificadores de la enfermedad se vislumbran como alternativas al corto plazo

Narrativas seriales e intimidad amatoria: estudio de caso de Grey's Anatomy

El aparecimiento de la televisión por cable implicó profundas transformaciones en los relatos mediáticos, particularmente en lo que respecta a las series televisivas, que rompen con la narrativa melodramática tradicional. El propósito de este trabajo es el de establecer la forma en que se narra el amor romántico, y que tipo de relación amorosa se representa, en una serie de televisión por cable que se emite en el Ecuador a través de Sony Entertainment: Grey’s Anatomy. Se indaga acerca del amor como un sistema de comunicación altamente complejo, y de resolución improbable, por la cantidad de variables que intervienen para que el amor pasión se consolide. Este sistema, por otra, parte tiene un sustrato genético determinado cerebralmente, cuando se produce simplemente es devastador. Las relaciones amorosas están condicionadas por factores culturales y sociales lo que obliga a establecer distinciones entre el amor romántico y la “relación pura” de pareja cuya característica es construirse a partir de la confianza y la “reflexividad” en la modernidad. Será la relación pura la que fundamentalmente se narre en la serie. La narrativa serial aprovecha esta experiencia universal del amor, para con recursos y técnicas que provienen del campo de la cinematografía establecer una narrativa amorosa particular. Formalmente el montaje, los planos y los movimientos de la cámara, se unen a los efectos emocionales que provoca la música en cada episodio para construir significaciones que conducen a despertar la rememoración emocional del espectador.

Dietary, physiological, genetic and pathological influences on postprandial lipid metabolism

Most of diurnal time is spent in a postprandial state due to successive meal intakes during the day. As long as the meals contain enough fat, a transient increase in triacylglycerolaemia and a change in lipoprotein pattern occurs. The extent and kinetics of such postprandial changes are highly variable and are modulated by numerous factors. This review focuses on factors affecting postprandial lipoprotein metabolism and genes, their variability and their relationship with intermediate phenotypes and risk of CHD. Postprandial lipoprotein metabolism is modulated by background dietary pattern as well as meal composition (fat amount and type, carbohydrate, protein, fibre, alcohol) and several lifestyle conditions (physical activity, tobacco use), physiological factors (age, gender, menopausal status) and pathological conditions (obesity, insulin resistance, diabetes mellitus). The roles of many genes have been explored in order to establish the possible implications of their variability in lipid metabolism and CHD risk. The postprandial lipid response has been shown to be modified by polymorphisms within the genes for apo A-I, A-IV, AN, E, B, C-I and C-III, lipoprotein lipase, hepatic lipase, fatty acid binding and transport proteins, microsomal trigyceride transfer protein and scavenger receptor class B type I. Overall, the variability in postprandial response is important and complex, and the interactions between nutrients or dietary or meal compositions and gene variants need further investigation. The extent of present knowledge and needs for future studies are discussed in light of ongoing developments in nutrigenetics.

An analysis of commercial real estate returns: an anatomy of smoothing in asset and index returns

In this article, we investigate the commonly used autoregressive filter method of adjusting appraisal-based real estate returns to correct for the perceived biases induced in the appraisal process. Many articles have been written on appraisal smoothing but remarkably few have considered the relationship between smoothing at the individual property level and the amount of persistence in the aggregate appraisal-based index. To investigate this issue we analyze a large sample of appraisal data at the individual property level from the Investment Property Databank. We find that commonly used unsmoothing estimates at the index level overstate the extent of smoothing that takes place at the individual property level. There is also strong support for an ARFIMA representation of appraisal returns at the index level and an ARMA model at the individual property level.

Integrated cytokine and metabolic analysis of pathological responses to parasite exposure in rodents

Parasitic infections cause a myriad of responses in their mammalian hosts, on immune as well as on metabolic level. A multiplex panel of cytokines and metabolites derived from four parasite-rodent models, namely, Plasmodium berghei-mouse, Trypanosoma brucei brucei-mouse, Schistosoma mansoni-mouse, and Fasciola hepatica-rat were statistically coanalyzed. 1H NMR spectroscopy and multivariate statistical analysis were used to characterize the urine and plasma metabolite profiles in infected and noninfected animals. Each parasite generated a unique metabolic signature in the host. Plasma cytokine concentrations were obtained using the ‘Meso Scale Discovery’ multi cytokine assay platform. Multivariate data integration methods were subsequently used to elucidate the component of the metabolic signature which is associated with inflammation and to determine specific metabolic correlates with parasite-induced changes in plasma cytokine levels. For example, the relative levels of acetyl glycoproteins extracted from the plasma metabolite profile in the P. berghei-infected mice were statistically correlated with IFN-γ, whereas the same cytokine was anticorrelated with glucose levels. Both the metabolic and the cytokine data showed a similar spatial distribution in principal component analysis scores plots constructed for the combined murine data, with samples from all infected animals clustering according to the parasite species and whereby the protozoan infections (P. berghei and T. b. brucei) grouped separately from the helminth infection (S. mansoni). For S. mansoni, the main infection-responsive cytokines were IL-4 and IL-5, which covaried with lactate, choline, and D-3-hydroxybutyrate. This study demonstrates that the inherently differential immune response to single and multicellular parasites not only manifests in the cytokine expression, but also consequently imprints on the metabolic signature, and calls for in-depth analysis to further explore direct links between immune features and biochemical pathways.
