Análisis comparativo de los desenlaces de neonatos con enfermedad hemolítica severa manejados con y sin inmunoglobulina

Objetivo: determinar la reducción de exanguinotransfusiones, estancia hospitalaria y complicaciones tempranas en recién nacidos con enfermedad hemolítica por el uso de inmunoglobulina endovenosa . Diseño: cohorte restrospectiva en la cual se compararon dos cohortes: 1) Recién nacidos con enfermedad hemolítica con uso de inmunoglobulina intravenosa a dosis de 0.5 gr/kg/dosis y 2) Recién nacidos con enfermedad hemolítica sin utilización de inmunoglobulina. Resultados: Exanguinotransfusiones: se encontró que el grupo con inmunoglobulina requirió 2,4% y el grupo sin inmunoglobulina requirió 8,3%, sin mostrar diferencias significativas (RR=0.286, IC 95%:0.033, 2.457, p=0.225). Efectos secundarios: tuvieron un comportamiento igual al de exanguinotransfusión con 2,4% en el grupo con inmunoglobulina y 8,3% en el grupo sin inmunoglobulina (RR= 0.286 , IC 95% 0.033, 2.457, p=0.225). Estancia hospitalaria: fue mayor en el grupo sin inmunoglobulina con una media de 5,9± 5.54 y mediana de 4 que en el grupo con inmunoglobulina con una media de 3,71± 1.95 y una mediana de 3.0 (p=0.002). Duración de la fototerapia: fue mayor en el grupo sin inmunoglobulina con media de 4.1±1.56 y mediana de 4 con respecto al grupo con inmunoglobulina con media de 3.52 ±1.53 y mediana de 3. Conclusión: el uso de inmunoglobulina en el manejo de recién nacidos con enfermedad hemolítica reduce de manera significativa la estancia hospitalaria y la duración de la fototerapia. Además tiene una tendencia a reducir la realización de exanguinotranfusiones y los efectos secundarios tempranos.Objetive: to determinate the reduction of realization of exanguinotransfusion, time of hospitalization and early complication in neonates with haemolytic disease secondary to the use of intravenous inmunoglobulin

Linear street extraction using a Conditional Random Field model

A novel method for extracting linear streets from a street network is proposed where a linear street is defined as a sequence of connected street segments having a shape similar to a straight line segment. Specifically a given street network is modeled as a Conditional Random Field (CRF) where the task of extracting linear streets corresponds to performing learning and inference with respect to this model. The energy function of the proposed CRF model is submodular and consequently exact inference can be performed in polynomial time. This contrasts with traditional solutions to the problem of extracting linear streets which employ heuristic search procedures and cannot guarantee that the optimal solution will be found. The performance of the proposed method is quantified in terms of identifying those types or classes of streets which generally exhibit the characteristic of being linear. Results achieved on a large evaluation dataset demonstrate that the proposed method greatly outperforms the aforementioned traditional solutions

Plasmatic Biochemical Variables Associated with Polymorphisms in the Endothelin-1 and Endothelin-1 Receptor a Genes in Hypertensive Patients: Pilot Study

Endothelin-1 (ET-1) is a potent vasoconstrictive peptide, and its activity is mediated by thetype A receptor (EDNRA). This action may play a significant role in the etiology of hypertension.There are different works that shows an association between certain polymorphisms of endothelinaxis and clinical phenotype of hypertension. We describe the genetic variability +138/ex1Short Research ArticleLassen et al.; BJMMR, 11(7): 1-8, 2016; Article no.BJMMR.205202insertion/deletion (I/D) adenosine (A) in the ET-1 gene and polymorphism thymidine/cytosine (T/C)His323His in the EDNRA gene associated at the clinical variability in hypertensive patients.Study Design: Observational, transversal and analytical study.Place and Duration of Study: Hypertension Service at the Internal Medicine Department ofCórdoba Hospital, and Biochemical and Molecular Biology Department in School of Medicine,National University of Cordoba, Argentine. Patients considered hypertensive between April 2009and April 2010.Methodology: Were assessed 136 patients serum lipid profiles, renal and hepatic functions andwere taken Thoracic X-rays, electrocardiograms, and echocardiographs. DNA extracted fromcirculating leukocyte were used to analyze the polymorphisms of genes by PCR-RFLP.Results: For the polymorphisms of Receptor A from Endothelin -1 studied the presence ofcytosine homozygous genotype was less frequent in males (P = .02). For both genders, the samegenotype was associated to low plasma alkaline phosphatase activity and cholesterol levels. Thepresence of thymidine nucleotide allele correlated with plasma alkaline phosphatase activity andcholesterol levels. The Thymidine allele correlated with the degree of cardiovascular compromise(r = 0.54, P= .002). For the genetic variant in the ET-1 gene, the homozygous adenine deletionwas associated to normal plasma levels of glutamate/pyruvate transaminase enzyme activity, uricacid concentration, cholesterol, and Low Density Lipoprotein in hypertensive subjects withoutclinical risk.Conclusion: We observed a gender-specific protective effect for EDNRA gene variations, thesubjects that carried the TT genotype presented more aggressive symptomatology. These resultsshow an association between plasmatic biochemical parameters, the clinical condition, andpolymorphisms in the endothelin axis genes.Fil: Lassen, Oscar. Universidad Nacional de Córdoba.
