Enfermedad linfoproliferativa postrasplante de órgano sólido

Con la denominacion enfermedad linfoproliferativa postrasplante (ELPT) se conoce un grupo de trastornos que se pueden presentar con posterioridad al trasplante de organos solidos, con incidencia variable dependiendo del tipo de organo trasplantado. La presentacion clinica inespecifica de esta enfermedad, el compromiso extranodal y su amplio espectro histopatologico hacen que tanto la clasificacion como el tratamiento sean complejos. Esta revision presenta una actualizacion sobre la ELPT en pacientes con trasplante de organo solido. Palabras clave: Infecciones por Virus de Epstein-Barr, Trasplante de Organos, Trastornos Linfoproliferativos
Return to Play After Multi-Ligament Knee Injuries in National Football League (NFL) Athletes

Objectives: Return to play (RTP) of NFL athletes following isolated ACL tears has been reported in the literature. However, there have been no studies reporting on RTP of NFL athletes following multi-ligament knee injuries. The authors hypothesize that NFL athletes with multi-ligament knee injuries will have lower RTP rates and longer time to RTP compared to athletes with isolated ACL tears, as reported in the literature. We also hypothesize that athletes with ACL and MCL injuries will have higher RTP rates and shorter time to RTP compared to athletes with an ACL tear and a PCL and/or LCL tear(s). Methods: NFL injury surveillance data was reviewed for all multi-ligament knee injuries between 2000 and 2016 with RTP information. Athletes were excluded if RTP was limited due to reasons unrelated to the injury such as suspension, unrelated injury, or personal matters. Extracted data included injury, RTP, time to return to play (months), number of games played, percent of possible games played, and performance. Results: 51 NFL athletes were found to have multi-ligament knee injuries between 2000 and 2016 that met inclusion and exclusion criteria. 47.1% (24/51) of athletes had ACL and MCL tears. 52.9% (27/51) of athletes had ACL and PCL and/or LCL tears. Of the players with ACL and PCL/LCL tears, there were 8 frank knee dislocations. The overall return to play rate following multi-ligament knee injuries was 62.7%. Athletes with ACL/MCL tears had an RTP rate of 70.8%, while the athletes with ACL and PCL/LCL tears had an RTP rate of 55.6% (p=.26). Athletes with frank knee dislocations had a 50% RTP rate. Mean time to RTP for all 51 athletes was 11.9 ± 3.52 months. The mean time to RTP for athletes with ACL/MCL injuries was 10.4±1.6 months compared with 13.7±4.3 for those with combined ACL and PCL/LCL injuries, and for frank dislocations was 20 ±6.1 (p<.001). Athletes with ACL/MCL injuries were more likely to return to prior performance levels 46% vs 18% compared to those with ACL and PCL/LCL injuries (p < .001). Conclusion: This study is the first to provide important prognostic information for NFL players sustaining multi-ligament knee injuries. The RTP rate for athletes with multi-ligament knee injuries is significantly less than the RTP rate for athletes with isolated ACL tears. In addition, athletes with ACL and MCL tears have a higher RTP rate, a significantly shorter time to RTP, and a higher likelihood of returning to prior performance than athletes with combined ACL and PCL/LCL tears.
Uncommon Transmission of HIV Infection Due to a Criminal Knife Fight

Appropriate screening for HIV infection is the cornerstone of HIV-related care. Clinicians should be aware of criminalizing HIV exposure and transmission. We report a case of HIV-1 infection transmission caused by a knife fight between addicts and criminals. He was overlooked as an innocent victim and infected his wife without diagnosis. He was injured with a bloody knife used to damage a man minutes before. His 33-year-old wife was admitted with respiratory distress and responded to the treatment of pneumocystosis. In workup for predisposing factor of this opportunistic infection, AIDS was confirmed. The possible route of HIV-1 transmission was investigated and concluded most likely resulted sexually from his husband. Both of them have no behavioral risk factor for HIV infection. Peoples and physicians should be educated about epidemiology, transmission, and pre- and post-exposure prophylaxis of HIV.
Comparison of Macintosh Laryngoscope and GlideScope® for Orotracheal Intubation in Children Older Than One Year

Objectives: We aim to investigate intubation conditions, intubation times, and hemodynamic response with the GlideScope video laryngoscope or the Macintosh direct laryngoscope for orotracheal intubation in children older than one year. Methods: Eighty patients aged 1–12 years, scheduled to undergo elective surgery under general anesthesia with endotracheal intubation were included in a prospective, single-blinded, randomized trial. Exclusion criteria were risk of pulmonary aspiration, craniofacial malformation, difficult intubation, emergency surgery, cardiovascular disease, respiratory disease, and hemodynamic instability. After standard anesthesia induction, patients were randomized into two groups. The group G patients (n=40) were intubated with the GlideScope and the group M patients (n=40) were intubated with the Macintosh laryngoscope. Intubation time, number of attempts, Cormack–Lehane score, airway maneuvers, and visual analog score were recorded. Hemodynamic variables were recorded before and after anesthesia induction, at intubation, and 1. , 3. , and 5. minutes after intubation. Student’s t-test, Mann–Whitney U test, and the χ2 test were used for statistical analysis, with p<0.05 considered significant. Results: The demographic data, operation time and hemodynamic parameters were similar between the two groups. The intubation time was longer in Group G than Group M. The incidence of Cormack–Lehane score 1 was higher in Group G than Group M while Cormack–Lehane score 2 was higher in Group M. Conclusion: We concluded that the GlideScope video laryngoscope provided better glottis visualization, but prolonged intubation time. There was no superiorty on hemodynamic effect with the video laryngoscope.
Calibration of a free-form surface mirror in a stereo vision system

The presence of repetitive patterns in the domain of stereo vision results in multiple matching hypotheses. Choosing the wrong hypothesis leads to an incorrect determination of objects and calculation of their distances. Especially in vision-based driver assistance and safety systems a high accuracy in matching and distance calculation is vital. One approach to increase the robustness of matching is to add a third camera to the system. Another idea is to resolve the ambiguities over time. In this paper we present a different solution without additional hardware expense: The shiny varnished hood of the car provides a mirror which is in a fixed position relative to the cameras. This mirror displays additional views of the scene, providing the required information. The cameras and the respective camera-mirror systems need to be calibrated. The epipolar geometry and the disparity-distance function of the free-form surface mirror must be determined. After establishing this we can obtain the correct matching hypothesis.

La digitalizacion de objetos tridimensionales se ha convertido en una de las herramientas mas utiles en el desarrollo de productos debido a la creciente utilizacion de las tecnicas de la ingenieria inversa en la manufactura de productos. La reproduccion de la geometria de los productos proporciona ventajas relacionadas con la reduccion de tiempos y costos con un alto grado de precision. Este trabajo presenta el diseno y la implementacion de un escaner tridimensional de superficies que permite reproducir las geometrias utilizando un instrumento de medicion constituido por una camara digital y un rayo laser posicionado por medio de un brazo robot. El trabajo comprende desde la calibracion del instrumento de medicion hasta la reconstruccion de la superficie del objeto en coordenadas 3D.
Descripción de un síndrome autoinmune similar a la esclerodermia humana en ratones deficientes para PSGL-1: Estudio traslacional en humanos

Previamente en nuestro grupo hemos demostrado que PSGL-1 es capaz de modular la funcion de las celulas dendriticas derivadas de monocitos obtenidos de sangre periferica de donantes humanos sanos, induciendo en ellas un programa tolerogenico que las capacita para generar celulas T reguladoras y que de acuerdo con esta funcion reguladora, las celulas dendriticas de ratones que carecen de PSGL-1 son inmunogenicas. Estos resultados sugerian que PSGL-1 podria ser importante en el desarrollo de la tolerancia periferica. Por otra parte, los enfermos con Esclerosis Sistemica tienen anormalmente activado el sistema inmune, y para su tratamiento se usan inmunosupresores generales (Manno R. and Boin F., 2010) El trabajo de esta tesis doctoral se ha llevado a cabo principalmente mediante analisis bioquimicos e histologicos de la piel, pulmones y rinones de los ratones PSGL-1 KO, ademas del estudio de su sistema inmune mediante citometria y ELISA para caracterizar las poblaciones celulares y los anticuerpos. Tambien se ha analizado la concentracion de PSGL-1 y sus ligandos en el suero de pacientes mediante ELISA.
Development of 3D finite-element charged-particle code with adaptive meshing

A number of new RF sources are in development that require complex analysis of steady-state, charged particle trajectories. A few codes are currently available; however, they are difficult to use and place severe demands on computational resources. A new program is nearing completion that addresses issues of problem setup and significantly reduce the computational requirements. In particular, the code accepts geometrical input from standard CAD of solid modeling programs, provides an intuitive graphical user interface for attribute assignment, and requires no user setup of the computational mesh. Meshing is fully automatic and adaptive. The mesh adaptation dramatically reduces the size of the computational problems, often by three orders of magnitude, while maintaining or increasing the accuracy over conventional fixed mesh codes. The program includes both electrostatic and magnetostatic field solvers and a fully relativistic particle pusher. The code is intended for engineers and scientist involved in design of the next generation of complex, 3D, charged particle devices.
Review Management of nonunion in trauma

Treatment of nonunion has radically changed in recent years. We define nonunion as a fracture of bone induced either by trauma or surgery which does not show clinical or radiographic signs of progression to healing within a reasonable time span. The reparative processes are present but inadequate. Fracture healing may be considered to be a balance between repair and breakdown processes at the fracture site. When breakdown exceeds repair, nonunion is the result. Altering the conditions at the fracture site even marginally in favour of repair will eventually lead to bony continuity being restored. Nonunion treatment should follow three principles: a) realignment; b) stabilization; and c) stimulation. Any surgical proce dure should address one or all of these areas. In this article the principles of nonunion management are explained, together with different bone healing stimulation techniques and our clinical results.
Online interactive activities to learn Ramayana epic by primary Tamil students

The Ramayana epic has many moral values that can be used as guidance in our daily life especially for the development of a person towards a better direction. Besides this, there are many other lessons that can be learned from within each Ramayana epic stories, for example, the values and norms, customs, mannerism lessons and the various characteristics of people and so on. But today’s digital or Net Generation teenagers do not find reading Ramayana as fun or interesting because of its text form. The technology is more advanced and Ramayana epics look very ancient in the eyes of this Digital Natives. This study used the idea of gamification, a game play mechanics to create meaningful learning experiences and make the learning more interesting and fun. Gamification also looks at games and learning from a different angle on how to make learning more meaningful, engaging, interactive, fun and interesting. In view of this, this research aims to seek if the use of online interactive activities could encourage and motivate teenagers to read Ramayana epics. Forty Primary Tamil students participated in this study voluntarily. The data were collected through a questionnaire. Based on the pre-questionnaire data regarding respondents’ prior knowledge on Ramayana, it was found that respondents had minimal knowledge about it. 37% said they would like to read the epic through comic books and 63% claimed that they would prefer computer. This study has some implications for computer assisted language learning.
Lexical and Language Modeling of Diacritics and Morphemes in Arabic Automatic Speech Recognition

Arabic is a morphologically rich language which rarely displays diacritics. These two features of the language pose challenges when building Automatic Speech Recognition (ASR) systems. Morphological complexity leads to many possible combinations of stems and affixes to form words, and produces texts with high Out Of Vocabulary (OOV) rates. In addition, texts rarely display diacritics which informs the reader about short vowels, geminates, and nunnations (word ending /n/). A lack of diacritics means that 30% of textual information is missing, causing ambiguities in lexical and language modeling when attempting to model pronunciations, and the context of a particular pronunciation. Intuitively, from an English centric view, the phrase thwrtr wrt n thwrt with ‘morphological decomposition’ is realized as, th wrtr wrt n th wrt. Including ‘diacritics’ produces, the writer wrote in the writ. Thus our investigations in this thesis are twofold. Firstly, we show the benefits and interactions between modeling all classes of diacritics (short vowels, geminates, nunnations) in the lexicon. On a Modern Standard Arabic (MSA) corpus of broadcast news, this provides a 1.9% absolute improvement in Word Error Rate (WER) (p < 0.001). We also extend this graphemic lexicon with pronunciation rules, yielding a significant improvement over a lexicon that does not explicitly model diacritics. This results in a of 2.4% absolute improvement in WER (p < 0.001). Secondly, we show the benefits of language modeling at the morphemic level with diacritics, over the commonly available, word-based, nondiacratized text. This yields an absolute WER improvement of 1.0% (p < 0.001). Thesis Supervisor: James R. Glass Title: Senior Research Scientist
A process-independent threshold voltage inverter-comparator for pulse width modulation applications

This paper presents a novel self-tuning inverter-comparator for a pulse width modulator. The inherent threshold voltage of the inverter-comparator is made independent of temperature and process variations by means of a self-tuning mechanism. The measured duty cycle error of the PWM at zero-input is typically 0.5%; an error /spl les/2% is typically specified. This is achieved without any post-fabrication trimming. The PWM is realized by a very simple circuit and can be readily fabricated in a low-cost digital CMOS process. The prototype IC met all design specifications and is suitable for micropower low-voltage applications including hearing instruments.
Controlling Perception Thresholds for Changing Timbres in Continuous Sounds

Perceptual dimensions underlying timbre and sound-source identification have received considerable scientific attention. While these scholarly insights help us in understanding the nature of sound within a multidimensional timbral space, they carry little meaning for the majority of musicians. To help address this, we conducted two experiments to establish listeners’ perceptual thresholds (PT) for changes in sound using a staircase-procedure. Unlike most timbre perception research, these changes were sonic manipulations that are common in synthesisers, audio processors and instruments familiar to musicians and producers, and occurred within continuous sounds (rather than between discrete pairs of sounds). In experiment 1, two sounds (variants of a sawtooth oscillation) both with the same fundamental frequency (F1: 80 Hz, 240 Hz or 600 Hz) were played with no intervening gap. In each trial, the two sounds’ partials differed in amplitudes or frequencies to produce a timbre change. The sonic manipulations were varied in size to detect thresholds for the perceived timbre change – listeners were instructed to indicate whether or not they perceived a change within the sound. In experiment 2, we modified stimulus presentation to introduce the factor of transition time (TT). Rather than occurring instantaneously (as in experiment 1), the timbre manipulations were introduced gradually over the course of a 100 ms or a 1000 ms TT. Results revealed that PTs were significantly affected by the manipulations in experiment 1, and additionally by TT in experiment 2. Importantly, the data revealed an interaction between the F1 and the timbre manipulations, such that there were differential effects of timbre changes on the perceptual system depending on pitch height. Musicians (n=11) showed significantly smaller PTs compared to non-musicians (n=10). However, PTs for musicians and non-musicians were highly correlated (r=.83) across different sonic manipulations, indicating similar perceptual patterns in both. We hope that by establishing PTs for commonly used timbre manipulations, we can provide musicians with a general perceptual unit, for each manipulation, that can guide music composition and assessment.
An Analytical Study for the Role of Fuzzy Logic in Improving Metaheuristic Optimization Algorithms

The research applications of fuzzy logic have always been multidisciplinary in nature due to its ability in handling vagueness and imprecision. This paper presents an analytical study in the role of fuzzy logic in the area of metaheuristics using Web of Science (WoS) as the data source. In this case, 178 research papers are extracted from it in the time span of 1989-2016. This paper analyzes various aspects of a research publication in a scientometric manner. The top cited research papers, country wise contribution, topmost organizations, top research areas, top source titles, control terms and WoS categories are analyzed. Also, the top 3 fuzzy evolutionary algorithms are extracted and their top research papers are mentioned along with their topmost research domain. Since neuro fuzzy logic poses feasible options for solving numerous research problems, hence a section is also included by the authors to present an analytical study regarding research in it. Overall, this study helps in evaluating the recent research patterns in the field of fuzzy metaheuristics along with envisioning the future trends for the same. While on one hand this helps in providing a new path to the researchers who are beginners in this field as they can start exploring it through the analysis mentioned here, on the other hand it provides an insight to professional researchers too who can dig a little deeper in this field using knowledge from this study.
L’approche des risques par la vulnérabilité : quels impacts sur la gestion de la rivière Quebrada Seca (Grande Aire Métropolitaine de San José, Costa Rica) ?

Dans le domaine de la gestion des risques environnementaux, la reduction de la vulnerabilite est devenue une approche dominante portee par des chercheurs en sciences humaines, des decideurs et des acteurs de terrain. A travers une etude de cas, cet article observe les effets de cette approche sur les pratiques de gestion du risque. Dans la Grande Aire Metropolitaine de San Jose au Costa Rica, deux collectifs de gestionnaires et de riverains de la riviere Quebrada Seca utilisent la notion de vulnerabilite afin de reduire l’exposition d’enjeux prioritaires (ressource hydrique, personne sinistree) a la pollution et aux inondations. L’utilisation de cette notion n’homogeneise pas les pratiques puisque chaque collectif defend une gestion du risque singuliere. Cependant, la caracterisation d’enjeux comme vulnerables les place sous la tutelle protectrice de la collectivite. Elle offre aux collectifs la possibilite d’assumer un role d’interface entre les enjeux et les decideurs afin de favoriser les engagements politiques et legaux.

A mathematical programming approach to the channel assignment problem in radio networks

The demand for mobile telephone service is increasing rapidly. A new formulation for the channel assignment problem (CAP) is proposed. The CAP has been formulated as an integer linear programming problem including compatibility and requirement constraints. For the solution of the resulting formulation conventional branch and bound methods have been used. The exploitation of the problem's special structure can improve the computational efficiency of the algorithm used. The algorithm has been applied to different benchmark problems that have appeared in the literature. The presented examples illustrate that using the proposed formulation and a specially designed branch and bound algorithm is possible to solve optimally and efficiently fairly large channel assignment problems.
Re-ECN: Adding Accountability for Causing Congestion to TCP/IP

This document introduces a new protocol for explicit congestion notification (ECN), termed re-ECN, which can be deployed incrementally around unmodified routers. The protocol arranges an extended ECN field in each packet so that, as it crosses any interface in an internetwork, it will carry a truthful prediction of congestion on the remainder of its path. Then the upstream party at any trust boundary in the internetwork can be held responsible for the congestion they cause, or allow to be caused. So, networks can introduce straightforward accountability and policing mechanisms for incoming traffic from end-customers or from neighbouring network domains. The purpose of this document is to specify the re-ECN protocol at the IP layer and to give guidelines on any consequent changes required to transport protocols. It includes the changes required to TCP both as an example and as a specification. It also gives examples of mechanisms that can use the protocol to ensure data sources respond correctly to congestion. And it describes example mechanisms that ensure the dominant selfish strategy of both network domains and end- points will be to set the extended ECN field honestly.
