Improving the Prediction of Spontaneous and Post-thrombolytic Recanalization in Ischemic Stroke Patients.

BACKGROUND: Endovascular treatment for acute ischemic stroke patients was recently shown to improve recanalization rates and clinical outcome in a well-defined study population. Intravenous thrombolysis (IVT) alone is insufficiently effective to recanalize in certain patients or of little value in others. Accordingly, we aimed at identifying predictors of recanalization in patients treated with or without IVT. METHODS: In the observational Acute Stroke Registry and Analysis of Lausanne (ASTRAL) registry, we selected those stroke patients (1) with an arterial occlusion on computed tomography angiography (CTA) imaging, (2) who had an arterial patency assessment at 24 hours (CTA/magnetic resonance angiography/transcranial Doppler), and (3) who were treated with IVT or had no revascularization treatment. Based on 2 separate logistic regression analyses, predictors of spontaneous and post-thrombolytic recanalization were generated. RESULTS: Partial or complete recanalization was achieved in 121 of 210 (58%) thrombolyzed patients. Recanalization was associated with atrial fibrillation (odds ratio , 1.6; 95% confidence interval, 1.2-3.0) and absence of early ischemic changes on CT (1.1, 1.1-1.2) and inversely correlated with the presence of a significant extracranial (EC) stenosis or occlusion (.6, .3-.9). In nonthrombolyzed patients, partial or complete recanalization was significantly less frequent (37%, P < .01). The recanalization was independently associated with a history of hypercholesterolemia (2.6, 1.2-5.6) and the proximal site of the intracranial occlusion (2.5, 1.2-5.4), and inversely correlated with a decreased level of consciousness (.3, .1-.8), and EC (.3, .1-.6) and basilar artery pathology (.1, .0-.6). CONCLUSIONS: Various clinical findings, cardiovascular risk factors, and arterial pathology on acute CTA-based imaging are moderately associated with spontaneous and post-thrombolytic arterial recanalization at 24 hours. If confirmed in other studies, this information may influence patient selection toward the most appropriate revascularization strategy.

Sullivan Agent Confesses, [1948]

The National Seaman’s Association was a labour recruiter hiding behind a union-like name. It was run by H.N. McMaster who collected fees from companies and dues from workers. With McMaster in charge, shipping interests could claim that their seamen had a union, but ship-owners were free to push their vessels and their workers to the breaking point. In 1935, the members on the Great Lakes decided to strike. One year later, they created their own union and amalgamated with a Montreal-based independent body to create the Canadian Seamen’s Union headed by a ship’s cook who became a union leader, John Allan Patrick “Pat” Sullivan. By the late 1940s, almost all sailors on Canadian ships were CSU members. Right from its inception in 1936, Communists were prominent among the leaders of the union. Sullivan had been recruited to the Communist party that year and the union had a close rapport with the party. On June 8, 1940, Pat Sullivan was arrested because of his affiliation with the Communist party. He was incarcerated until March 20, 1942. No charges were laid, no bail was set and there was no trial. After his release, Sullivan was elected second vice-president of the Trades and Labour Congress of Canada. In 1943, Percy Bengough was elected as president and Sullivan was elected as secretary treasurer of the TLC while maintaining his role as president of the CSU. On March 14, 1947 Sullivan made a shocking announcement that he was resigning from the CSU and the Labor-Progressive Party. He claimed that the CSU was under the full control of the Communists. Within a month of this announcement, he emerged as the president of the Canadian Lake Seamen’s Union. Ship-owners never really reconciled themselves to having their industry unionized, and in 1946 there was a seamen’s strike in which the union won the eight-hour day. In 1949, the shipping companies had a plan to get rid of the union and were negotiating behind their back with the Seafarers International Union (SIU). In a brutal confrontation, led by Hal Banks, an American ex-convict, the SIU was able to roust the CSU and take over the bargaining rights of Canadian seamen. On July 15, 1948, Robert Lindsay, who was Sullivan’s Welland business agent said that to the best of his knowledge, Sullivan’s outfit, the CLSU, was under the control of some of the Steamship Companies. Lindsay had heard that there was a movement to get rid of Bengough of the Trades and Labour Congress as well as elements of the CSU. He also had heard that the CLSU wanted to affiliate with the American Federation of Labor. Lindsay’s allegations raised the questions: Were the ship-owners powerful enough to oust Percy Bengough because he supported the seamen? Could the CLSU get an affiliation with the American Federation of Labor? and Would the American Federation of Labor actually affiliate with a union that was siding with employers against a locked-out union?

Por mi voz habla el Ejército Zapatista de Liberación Nacional’ la evolución discursiva del zapatismo en las declaraciones de la selva lacandona, 1994-1996

El propósito de este artículo es definir la naturaleza y el proceso evolutivo del discurso del EZLN (Ejército Zapatista de Liberación Nacional) en su etapa temprana de presencia pública, de 1994 a 1996. El análisis de discurso propuesto está enfocado en identificar los parámetros por medio de los cuales los zapatistas entablan diálogos con el gobierno mexicano y con la sociedad civil nacional e internacional, en el marco de su lucha de emancipación. Dichos parámetros son identificados mediante la lectura detallada de las cuatro Declaraciones de la Selva Lacandona, las cuales, concebidas por los zapatistas como sus instrumentos privilegiados de comunicación con la sociedad civil, pueden ayudarnos a identificar el terreno en el que establecen sus bases ideológicas y operativas, como movimiento político y percibir las diferentes forma de manifestación de su proyecto político e ideológico. La metodología utilizada para realizar una lectura detallada de estos textos está influida en gran medida por la propuesta heurística de Ernesto Laclau y Chantal Mouffe, sobre el análisis de luchas políticas que intentan cuestionar y desplazar poderes y discursos hegemónicos, en el ámbito de lo político y lo ideológico.---The purpose of this article is to define the EZLN (Zapatista Army of National Liberation) discourse, its nature and the evolving process involved in its early public presence, between 1994 and 1996. The proposed discourse analysis is focused to identify the parameters used by the zapatistas to carry out dialogue processes with the Mexican Government, national and international civil society, whilst undertaking their emancipatory struggle. These parameters are identified through a close reading of the four Declarations of the Lacandona Jungle, conceived by the zapatistas as privileged instruments for the communication of their message to civil society. The latter can provide interesting insights on the ideological and operative basis of this political movement, as well as the different levels of manifestation of the zapatista political and ideological project. The methodology that is used to elaborate a detailed reading of these texts is influenced greatly by the political thought of Ernesto Laclau y Chantal Mffe. Laclau and Mouffe have long reflected on the possibility of analysing political struggles that attempt to question and displace hegemonic discourse and powers in the ideological and political field.

Both have reflected on the possibility of analysing political struggles thatattempt to question and displace hegemonic discourse and powers in the ideological and political field.

Actitudes hacia el VIH/SIDA, el cáncer y la enfermedad de Alzheimer

Esta revisión de la literatura tuvo como objetivo describir las actitudes hacia el VIH/SIDA, el cáncer y la Enfermedad de Alzheimer desde el modelo tripartito. Se revisaron 109 artículos publicados entre 2005 y 2015 en algunas bases de datos especializadas y herramientas de análisis de impacto. También se incluyeron fuentes secundarias ampliándose la búsqueda a los últimos 20 años (1995-2015). Los resultados mostraron que la mayoría de los estudios realizados sobre las actitudes hacia estas tres enfermedades son de tipo cuantitativo y la información se analizó con base en los componentes del modelo tripartito. Algunos aspectos sociodemográficos como el sexo y la edad están asociados con las actitudes hacia las tres enfermedades y predominan las creencias erróneas sobre ellas respecto a sus causas, curso y tratamiento. También predominan actitudes negativas hacia las tres enfermedades y las conductas e intenciones conductuales son diversas hacia cada una de ellas. No se hallaron antecedentes empíricos del estudio de la estructura de las actitudes propuesta por el modelo tripartito hacia las tres enfermedades. La Salud Pública ha liderado la investigación con base en el modelo de conocimientos, actitudes y prácticas propuesto por la OMS.

Plan de intervención en seguridad humana 75-cien, un análisis desde la implementación de políticas públicas en materia de seguridad ciudadana en Bogotá. Estudio de caso UPZ Las Cruces

La presente investigación tiene como objetivo principal, explicar la influencia de la línea de intervención de Seguridad Humana del plan 75-cien, en la seguridad ciudadana de la UPZ Las Cruces, con el fin de demostrar que la política pública no influye de manera significativa en la seguridad ciudadana de la UPZ Las Cruces, ante la participación casi nula de la Policía Nacional en el proyecto. A pesar de que la intervención focaliza el territorio y prioriza las necesidades sociales, el vacío que existe en el trabajo conjunto entre la Policía y la Secretaria Distrital de Gobierno, implica que no se establezcan acciones policivas que acompañen las estrategias de desarrollo humano para evitar o disuadir el delito. Por lo tanto a partir de la utilización del método cualitativo, se recolectaran datos de grupos focales, informes de las fuentes primarias y un diagnóstico de la línea de intervención, que permitan un análisis descriptivo y explicativo del fenómeno.

A vilegiatura marítima e a urbanização em Tibau/RN

This research aims the analysis of the urbanization process that has taken place in the coastal city of Tibau/RN in the period comprising 1980-2012, due to the (re) production of space to consumption of leisure and recreation, through the so called practice of Maritime Villeggiatura. Such practice exists so that people settle temporarily on the beach as a second home, interfering in the Regulation of the land use as well as in the urban planning of Tibau, promoting urbanization based in the logic of leisure, with enormous capacity for appropriation and space consumption. The practice of Maritime Villeggiatura in Tibau began in the late nineteenth century, becoming more relevant in the 1980s, when the practice became fashionable for the citizens of Mossoró City, in view of their economic strength, and consumption power to invest in this type of domicile. Tibau has become a great depository of second homes for leisure practice, which contributed even to the city administrative and political emancipation in 1997. The intensification of Real Estate activities, expanding second homes along the coast, results in the urbanization of Tibau territory with the assistance of Local Government, whom was interested in entering Tibau on the State tourism routes. The used methodology comprised literature review, data collection and local observation. Questionnaires were applied in the form of interviews to the villeggiaturistas, local residents, business and trade services local companies, a local agricultural firm named Agricultura Famosa Ltda., Municipal government and the Association of Senior Citizens of the municipality of Tibau. A photographic record was made to visualize the urbanization evolution of Tibau. It has also been taken georeference measures of the area object of study in this research, in order to analyze the use and occupation of the territory by urban and social agents villeggiaturistas and residents. The conclusion is that the urbanization process that has been taken in Tibau occurred along the coast shore, with low population density, and therefore creating difficulties to governance of the Municipal government. Real Estate Sector has been promoting the value increase of urban land in order to fragment the space with private condominiums segregating local resident population to outlying areas of the city, away from the coastline and lacking infrastructure and basic urban services
