Diagnóstico de la ehrlichiosis monocítica canina: una revisión actualizada
Authors: Rodríguez-Vivas Roger Iván , Bolio-González Manuel Emilio , Ojeda-Chi Melina Maribel 
Published: April 2016

<p>La ehrlichiosis monocítica canina (EMC) es causada por la infección de una rickettsia denominada Ehrlichia canis; este microorganismo se reproduce solamente en el citoplasma de los monocitos sanguíneos y macrófagos tisulares. La EMC ha sido reportada en todo el mundo, pero las frecuencias más altas se reportan en las regiones tropicales y subtropicales. La EMC no siempre es reconocida clínicamente, pues es difícil de diagnosticar debido a que los signos clínicos son variables, a que se presenta en diferentes fases y a la existencia de coinfecciones con otros patógenos transmitidos por garrapatas y otros agentes infecciosos. Las manifestaciones clínicas y las técnicas de diagnóstico tradicionales, como el diagnóstico hematológico y la demostración típica de mórulas de E. canis en el citoplasma de monocitos en frotis sanguíneos, se han utilizado para el diagnóstico de la EMC; sin embargo, las pruebas de diagnóstico por PCR y la serología mediante el uso de antígenos específicos son las pruebas más sensibles y específicas para el diagnóstico de la enfermedad. Este artículo presenta una revisión actualizada sobre el diagnóstico de la infección por E. canis en perros.</p>

Published: April 2016

<p>El objetivo del presente estudio fue cuantificar la ivermectina eliminada en la materia fecal del ganado bovino, la cual fue detectada mediante la técnica de Cromatografía Líquida de Alta Resolución (CLAR), en la granja experimental Tunguavita, en la vereda Salitre de la ciudad de Paipa (Boyacá). Se experimentó en 10 novillas de diferentes razas y pesos con ivermectina comercial al 1% en una dosis de 0,2 mg/kg de peso vivo, por vía subcutánea en una sola aplicación. Se observó que al segundo día de haber aplicado el antiparasitario se obtuvo la concentración más alta (87.6%), y a los 20 días, la más baja (0,17%); es decir, la concentración de ivermectina fue disminuyendo, aproximadamente, en 0.0535 ppm por día. No se encontraron diferencias significativas entre razas y pesos de los animales. Los resultados de este estudio muestran la presencia de ivermectina en las heces del ganado bovino, presencia que genera un impacto ambiental negativo frente a la entomofauna coprófaga, encargada de la degradación de la materia fecal, ya que las diferentes concentraciones de ivermectina continúan con su función insecticida al ser eliminadas en la materia fecal.<br />De otro lado, se determinó que cierta parte del desparasitante está siendo asimilado por diferentes órganos internos del individuo, por lo tanto, no se eliminan en su totalidad.</p>
Colombia y su participación en la Guerra de Corea: Una reflexión tras 64 años de iniciado el conflicto
Authors: Meléndez Camargo Juan David 
Published: April 2016

El texto hace una reflexión sobre la participación de Colombia en la Guerra de Corea y las implicaciones políticas que tuvo para el país. Dicha participación generó mucha polémica porque Colombia fue el único país latinoamericano que colaboró con la causa norteamericana para derrotar la expansión del comunismo. En este contexto geopolítico de la Guerra Fría se iniciaron las llamadas “guerras satélite” patrocinadas por los Estados Unidos y la extinta Unión Soviética. Para este estudio, la prensa de circulación colombiana es de gran relevancia porque permite hacer seguimiento al desarrollo de esa confrontación armada, desde la perspectiva de los soldados colombianos y lo que esta intervención le dejó al Ejército y al país. En términos generales la competencia ideológica de Estados Unidos y la URSS, que inició tras la Segunda Guerra Mundial, vinculó a muchas naciones tercermundistas en la coyuntura del agitado orden político mundial y polarizó sus relaciones políticas.
Sobre la función de policía y el orden económico en San Miguel de Tucumán a fines del siglo XVIII. De presuntos delincuentes, acaparadores y monopolistas
Authors: Zamora Romina Noemí 
Published: April 2016

Este trabajo busca abordar el problema del surgimiento de la función de policía en el Río de la Plata como parte del pensamiento ilustrado de ines del siglo XVIII, con especial atención al caso de la ciudad de San Miguel de Tucumán. El objetivo es señalar algunos elementos deinitorios de esta función tal como era entendida por sus contemporáneos: como un nuevo terreno disciplinar relacionado con el buen orden y la buena convivencia, con una multiplicidad de funciones y acciones. Es de destacar la diferencia que existía entre el discurso de policía y el de justicia, ya que mientras la justicia actuaba a partir de la potestad jurisdiccional de los jueces, la función de policía a cargo de los vecinos y padres de familia justiicaba su existencia en clave tuitiva, tutelando el orden público sobre la base de una potestad doméstica o economica. Utilizando metodología de la antropología jurídica, se propone como hipótesis que la función de policía surgió como campo normativo en estrecha relación con la economía, en el control de los precios, de la competencia, el fomento a la producción y el control sobre los pobres. Para eso se analizarán sus instrumentos jurídicos y algunos de sus principales campos de aplicación.
Michel Foucault y la Contra-Historia
Authors: Márquez Estrada José Wilson 
Published: April 2016

En el presente artículo se construye un análisis de la propuesta historiográica de Michel Foucault y las características de su método genealógico. Igualmente se abordará el problema del sujeto y el concepto acontecimiento dentro del contexto de su propuesta histórica. También se analizará la cuestión del método y su articulación con el oficio especíico del historiador que Foucault propone como ejercicio genealógico y arqueológico. En este sentido, se realizará un análisis diferenciador de estos dos conceptos y su papel en la propuesta historiográica del pensador francés. Igualmente se abordará el tema del sujeto y su importancia en el contexto de la obra de Foucault. Finalmente se mostrará el valor de la visión historiográica foucaultiana dentro del contexto de la historiografía occidental, haciendo énfasis en su posición de ruptura frente a la historia tradicional, ruptura planteada en términos de una contra-historia.
What Makes Underwriting and Non-Underwriting Clients of Brokerage Firms Receive Different Recommendations?
Authors: Hua Shaowen 
Published: April 2016

I explore company characteristics which explain the difference in analysts’ recommendations for companies that were underwritten (affiliated) versus non-underwritten (unaffiliated) by analysts’ brokerage firms. Prior literature documents that analysts issue more optimistic recommendations to underwriting clients of analysts’ brokerage employers. Extant research uses regression models to find general associations between recommendations and financial qualities of companies, with or without underwriting relationship. However, regression models cannot identify the qualities that cause the most difference in recommendations between affiliated versus unaffiliated companies. I adopt uplift random forest model, a popular technique in recent marketing and healthcare research, to identify the type of companies that earn analysts’ favor. I find that companies of stable earnings in the past, higher book-to-market ratio, smaller sizes, worsened earnings, and lower forward PE ratio are likely to receive higher recommendations if they are affiliated with analysts than if they are unaffiliated with analysts. With uplift random forest model, I show that analysts pay more attention on price-related than earnings-related matrices when they value affiliated versus unaffiliated companies. This paper contributes to the literature by introducing an effective predictive model to capital market research and shedding additional light on the usefulness of analysts’ reports.
Time-Lapse Seismic for Reservoir Management: Case Studies From Offshore Niger Delta, Nigeria

Published: April 2016

Summary
This paper presents case studies focused on the interpretation and integration of seismic reservoir monitoring from several fields in conventional offshore and deepwater Niger Delta. The fields are characterized by different geological settings and development-maturity stages. We show different applications varying from qualitative to quantitative use of time-lapse (4D) seismic information.
In the first case study, which is in shallow water, the field has specific reservoir-development challenges, simple geology, and is in phased development. On this field, 4D seismic, which was acquired several years ago, is characterized by poor seismic repeatability. Nevertheless, we show that because of improvements from seismic reprocessing, 4D seismic makes qualitative contributions to the ongoing field development.
In the second case study, the field is characterized by complex geological settings. The 4D seismic is affected by overburden with strong lateral variations in velocity and steeply dipping structure (up to 40°). Prestack-depth-imaging (PSDM) 4D seismic is used in a more-qualitative manner to monitor gas injection, validate the geologic/reservoir models, optimize infill injector placement, and consequently, enhance field-development economics.
The third case study presents a deep offshore field characterized by a complex depositional system for some reservoirs. In this example, good 4D-seismic repeatability (sum of source- and receiver-placement differences between surveys, dS+dR) is achieved, leading to an increased quantitative use of 4D monitoring for the assessment of sand/sand communication, mapping of oil/water (OWC) front, pressure evolution, and dynamic calibration of petro-elastic model (PEM), and also as a seismic-based production-logging tool. In addition, 4D seismic is used to update seismic interpretation, provide a better understanding of internal architecture of the reservoirs units, and, thereby, yield a more-robust reservoir model. The 4D seismic in this field is a key tool for field-development optimization and reservoir management.
The last case study illustrates the need for seismic-feasibility studies to detect 4D responses related to production. In addition to assessing the impact of the field environment on the 4D- seismic signal, these studies also help in choosing the optimum seismic-survey type, design, and acquisition parameters. These studies would possibly lead to the adoption of new technologies such as broad-band streamer or nodes acquisition in the near future.

AbstractBackgroundFunctional impairment is common in people with chronic liver disease (CLD), and improvement is expected following liver transplantation (LT). The Six-Minute Walk Test (6MWT) is an objective measure of functional performance.ObjectiveThe aims of this study were: (1) to evaluate the feasibility of 6MWT performance after LT, (2) to compare post-LT 6MWT performance over time between patients with and without CLD, (3) to determine when post-LT 6MWT performance approaches expected values, and (4) to investigate predictors of poor 6MWT performance.MethodsThe 6MWT was performed by 162 consecutive ambulatory participants (50 healthy controls, 62 with CLD, 50 with LT). Sex, age, and body mass index were used to predict expected 6MWT performance. Chi-square testing, analysis of variance, and Pearson coefficients compared percentage of predicted 6-minute walk distance (%6MWD) across groups. Multivariable mixed models assessed predictors of improvement.ResultsThe participants' mean age was 53.5 years (SD=13.0), 39.5% were female, and 39.1% were nonwhite. At 1-month post-LT, only 52% of all LT recipients met the inclusion criteria for 6MWT performance. Mean %6MWD values for female participants improved from 49.8 (SD=22.2) at 1 month post-LT to 90.6 (SD=12.8) at 1 year post-LT (P&lt;.0001), which did not differ statistically from the CLD group (X̅=95.9, SD=15.6) or the control group (X̅=95.6, SD=18.0) (P=.58). However, at 1-year post-LT, mean %6MWD values for male participants (X̅=80.4, SD=19.5) remained worse than for both the CLD group (X̅=93.3, SD=13.7) and the control group (X̅=91.9, SD=14.3) (P=.03). Six-Minute Walk Test performance was directly correlated with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) physical component score (r=.51, P&lt;.01) and was inversely correlated with nonalcoholic steatohepatitis (r=−.52, P&lt;.01) and diabetes (r=−.48, P&lt;.05). In multivariate analysis adjusted for age and sex, hepatitis C independently predicted 6MWT improvement (estimated β=69.8, standard error=27.6, P=.01).LimitationsA significant proportion of patients evaluated for enrollment were excluded due to level of illness early after LT (n=99, 47.4%). Thus, sampling bias occurred in this study toward patients without significant postoperative complications.ConclusionsThe 6MWT is a simple test of physical functioning but may be difficult to apply in LT recipients. The 6MWT performance improved following LT but was lower than expected, suggesting a low level of fitness up to 1 year following LT.

OBJECTIVE
Chronic frontal hemodynamic disturbances are associated with executive dysfunction in adult patients with moyamoya disease (MMD). However, the impact of surgical revascularization on executive dysfunction and its underlying mechanism remains unclear. The aim of the present study was to examine the postoperative radiological correlates of cognitive improvement and thereby explore its underlying mechanism.

METHODS
Fourteen patients who met the inclusion criteria were identified at Huashan Hospital, were operated on, and were successfully followed up for 6 months. Postoperative changes in cortical perfusion and regional amplitude of low-frequency fluctuations (ALFF) were examined by SPECT and resting-state functional MRI, respectively. Executive function was evaluated by 2 tests (Trail Making Test Part B and the summation of executive subtests of Memory and Executive Screening [MES-EX]). Follow-up neuropsychological outcomes were then correlated with radiological changes to identify nodes functioning as leading contributors to postoperative executive outcomes.

RESULTS
All patients underwent successful unilateral bypass procedures, with some operations performed on the left side and some on the right side. At the 6-month follow-up, the baseline and follow-up test scores for the different sides did not differ significantly. The group with good collaterals (Matsushima Grade A, 9 patients) exhibited significantly increased postoperative perfusion (change in [△] hemodynamics) in bilateral frontal (left, p = 0.009; right, p = 0.003) and left parietal lobe (p = 0.014). The Spearman's correlation test suggested that only the right frontal lobe exhibited significant positive postoperative radiological correlates with cognitive performance (△MES-EX vs △hemodynamics, r = 0.620, p = 0.018; △MES-EX vs △ALFF, r = 0.676, p = 0.008; △hemodynamics vs △ALFF, r = 0.547, p = 0.043). Subsequent regional ALFF analysis revealed that the right dorsolateral prefrontal cortex (DLPFC) was the only node in the responsible hemisphere to exhibit significant postoperative changes.

CONCLUSIONS
The results not only advance our understanding of pathological interactions of postoperative executive performance in adult MMD, but also indicate that the right DLPFC amplitude might be a quantitative predictor of postoperative executive control improvement.
Meningioma consistency prediction utilizing tumor to cerebellar peduncle intensity on T2-weighted magnetic resonance imaging sequences: TCTI ratio
Authors: Smith Kyle A. , Leever John D. , Hylton Phillip D. , Camarata Paul J. , Chamoun Roukoz B. 
Published: April 2016

OBJECTIVE
Meningioma consistency, firmness or softness as it relates to resectability, affects the difficulty of surgery and, to some degree, the extent of resection. Preoperative knowledge of tumor consistency would affect preoperative planning and instrumentation. Several methods of prediction have been proposed, but the majority lack objectivity and reproducibility or generalizability to other surgeons. In a previous pilot study of 20 patients the authors proposed a new method of prediction based on tumor/cerebellar peduncle T2-weighted imaging intensity (TCTI) ratios in comparison with objective intraoperative findings. In the present study they sought validation of this method.

METHODS
Magnetic resonance images from 100 consecutive patients undergoing craniotomy for meningioma resection were evaluated preoperatively. During surgery a consistency grade was prospectively applied to lesions by the operating surgeon, as determined by suction and/or cavitron ultrasonic surgical aspirator (CUSA) intensity. Consistency grades were A, soft; B, intermediate; and C, fibrous. Using T2-weighted MRI sequences, TCTI ratios were calculated. Analysis of the TCTI ratios and intraoperative tumor consistency was completed with ANOVA and receiver operating characteristic curves.

RESULTS
Of the 100 tumors evaluated, 50 were classified as soft, 29 as intermediate, and 21 as firm. The median TCTI ratio for firm tumors was 0.88; for intermediate tumors, 1.5; and for soft tumors, 1.84. One-way ANOVA comparing TCTI ratios for these groups was statistically significant (p < 0.0001). A single cutoff TCTI value of 1.41 for soft versus firm tumors was found to be 81.9% sensitive and 84.8% specific.

CONCLUSIONS
The authors propose this T2-based method of tumor consistency prediction with correlation to objective intraoperative consistency. This method is quantifiable and reproducible, which expands its usability. Additionally, it places tumor consistency on a graded continuum in a clinically meaningful way that could affect preoperative surgical planning.
