Frecuencia cardĂaca al ingreso como factor asociado a mortalidad intrahospitalaria en pacientes con sĂndrome coronario agudo
Objetivo: Determinar si la frecuencia cardiaca al ingreso es un factor asociado a mortalidad intrahospitalaria en pacientes con sĂndrome coronario agudo.
Material y mĂ©todos: Se llevĂł a cabo un estudio retrospectivo, analĂtico, transversal en el que se incluyeron a 171 pacientes con sĂndrome coronario agudo, del hospital VĂctor Lazarte Echegaray, durante el periodo 2014-2018, que cumplan los criterios de selecciĂłn; los cuales se dividieron en 2 grupos: 35 pacientes fallecidos y 136 sobrevivientes; aplicándose el odds ratio, y la prueba estadĂstica chi cuadrado.
Resultados: El promedio de edad, diabetes mellitus, hipertensiĂłn arterial y clase funcional Killip III y IV fueron significativamente mayores en el grupo de fallecidos que en el de sobrevivientes (p<0.05). La taquicardia es factor asociado a mortalidad intrahospitalaria en pacientes con sĂndrome coronario agudo con un odds ratio de 4.1 el cual fue significativo (p<0.05). La bradicardia es factor asociado a mortalidad intrahospitalaria en pacientes con sĂndrome coronario agudo con un odds ratio de 5.4 el cual fue significativo (p<0.05). En el análisis multivariado se reconoce a la taquicardia, bradicardia, diabetes mellitus, hipertensiĂłn arterial y clase funcional Killip III y IV como factores asociados a mortalidad en pacientes con sĂndrome coronario agudo (p<0.05).
ConclusiĂłn: La frecuencia cardiaca al ingreso es un factor asociado a mortalidad intrahospitalaria en pacientes con sĂndrome coronario agudo.Objective: To determine if the heart rate at admission is a factor associated with in-hospital mortality in patients with acute coronary syndrome.
Material and methods: A retrospective, analytical, cross-sectional study was carried out in which 171 patients with acute coronary syndrome were included, from the Victor Lazarte Echegaray hospital, during the 2014-2018 period, which met the selection criteria which were divided into 2 groups : 35 deceased patients and 136 survivors; applying the odds ratio, and the chi-square statistical test.
Results: The average age and frequency of diabetes mellitus, arterial hypertension and functional class Killip III and IV were significantly higher in the group of deaths than in the group of survivors (p <0.05). Tachycardia is a factor associated with in-hospital mortality in patients with acute coronary syndrome with an odds ratio of 4.1 which was significant (p <0.05). Bradycardia is a factor associated with in-hospital mortality in patients with acute coronary syndrome with an odds ratio of 4.1 which was significant (p <0.05). In the multivariate analysis, tachycardia, bradycardia, diabetes mellitus, arterial hypertension and Killip III and IV functional class are recognized as factors associated with mortality in patients with acute coronary syndrome (p <0.05).
Conclusion: The heart rate at admission is a factor associated with in-hospital mortality in patients with acute coronary syndrome.Tesi
Joint management of marine mammals and a fish species : The case of cod and grey seals in the Nordic-Baltic Sea countries
In this paper, we present a simple theoretical, steady-state equilibrium, predator-prey model for the joint management of marine mammals and a fish species. As an empirical case, we choose cod and grey seals in the Nordic-Baltic Sea countries, and several benefits and costs related to the latter are considered. We show that the optimal grey seal population is much lower than the actual population, and this result is robust to variations in relevant parameter values. This result can be explained by the fact that the profit from harvesting cod is much higher than the net benefits from grey seals.Peer reviewe

Nordic fisheries and aquaculture:Socio-economic importance of nitrogen nutrient load in the environment
This report contributes to the understanding of how the the socio-economic contribution of Nordic fisheries/aquaculture are affected by the environment and environmental management, with focus on nitrogen. The report contains two case studies of how the socio-economic contribution of Danish/Swedish cod fishery in the Western Baltic Sea are affected by the nitrogen in the sea, and on how salmon growth rates in aquaculture in the Bokna Fiord are affected by nitrogen concentration. A Nordic workshop was held with the title: Fisheries, aquaculture and the marine environment: Environmental challenges and regulation, with focus on nitrogen. The finding of the case studies was presented at the workshop, together with presentations made by invited speakers on the role of nutrients and their management for Nordic fisheries/aquaculture. The discussion at the workshop is summarized in this report
Kinect-Based Correction of Overexposure Artifacts in Knee Imaging with C-Arm CT Systems
Objective. To demonstrate a novel approach of compensating overexposure artifacts in CT scans of the knees without attaching any supporting appliances to the patient. C-Arm CT systems offer the opportunity to perform weight-bearing knee scans on standing patients to diagnose diseases like osteoarthritis. However, one serious issue is overexposure of the detector in regions close to the patella, which can not be tackled with common techniques. Methods. A Kinect camera is used to algorithmically remove overexposure artifacts close to the knee surface. Overexposed near-surface knee regions are corrected by extrapolating the absorption values from more reliable projection data. To achieve this, we develop a cross-calibration procedure to transform surface points from the Kinect to CT voxel coordinates. Results. Artifacts at both knee phantoms are reduced significantly in the reconstructed data and a major part of the truncated regions is restored. Conclusion. The results emphasize the feasibility of the proposed approach. The accuracy of the cross-calibration procedure can be increased to further improve correction results. Significance. The correction method can be extended to a multi-Kinect setup for use in real-world scenarios. Using depth cameras does not require prior scans and offers the possibility of a temporally synchronized correction of overexposure artifacts. To achieve this, we develop a cross-calibration procedure to transform surface points from the Kinect to CT voxel coordinates

Jimmy Swaggart's Secular Confession
This is the author's accepted manuscript. The published version is available from http://dx.doi.org/10.1080/02773940902766748 .Following the exposure of televangelist Jimmy Swaggart’s illicit rendezvous with a New Orleans prostitute, the Assemblies of God simultaneously orchestrated a massive attempt to silence those who would discuss the tryst and arranged the most widely publicized confession in American history theretofore. The coincidence of a “silence campaign” with the vast distribution of a public confession invites us to reconsider the nature of the public confession. For what place has a public confession, the discourse of disclosure par excellence, in a silence campaign? This question is best answered, I argue, if we understand public confession not as a stable a-historical form, but as a practice that is informed by multiple, competing traditions. I argue that by situating Swaggart’s performance in a philosophically modern and secular tradition of public confession we can understand both its complicity in a silence campaign and, more generally, the political logic of the modern public confession

Endothelial Neuropilin Disruption in Mice Causes DiGeorge Syndrome-Like Malformations via Mechanisms Distinct to Those Caused by Loss of Tbx1
The spectrum of human congenital malformations known as DiGeorge syndrome (DGS) is replicated in mice by mutation of Tbx1. Vegfa has been proposed as a modifier of DGS, based in part on the occurrence of comparable phenotypes in Tbx1 and Vegfa mutant mice. Many additional genes have been shown to cause DGS-like phenotypes in mice when mutated; these generally intersect in some manner with Tbx1, and therefore impact the same developmental processes in which Tbx1 itself is involved. In this study, using Tie2Cre, we show that endothelial-specific mutation of the gene encoding the VEGFA coreceptor neuropilin-1 (Nrp1) also replicates the most prominent terminal phenotypes that typify DGS. However, the developmental etiologies of these defects are fundamentally different from those caused by absence of TBX1. In Tie2Cre/Nrp1 mutants, initial pharyngeal organization is normal but subsequent pharyngeal organ growth is impaired, second heart field differentiation is normal but cardiac outflow tract cushion organization is distorted, neural crest cell migration is normal, and palatal mesenchyme proliferation is impaired with no change in apoptosis. Our results demonstrate that impairment of VEGF-dependent endothelial pathways leads to a spectrum of DiGeorge syndrome-type malformations, through processes that are distinguishable from those controlled by Tbx1
