Cirugía abierta como manejo de enfermedad varicosa pélvica

El dolor pélvico crónico es un motivo frecuente de consulta, que está presente hasta en un 40% de las mujeres, y que afecta de manera considerable su calidad de vida. El síndrome de congestión pélvica asociado a varices constituye un factor etiológico de esta patología; sin embargo, existe poca evidencia que describa la eficacia y seguridad de la técnica quirúrgica abierta. Este estudio evalúa los resultados clínicos de la cirugía abierta para el manejo de las várices pélvicas. Metodología: se realizó un estudio descriptivo de corte transversal con 94 pacientes con varices gonadales, sometidas a cirugía abierta. Se evaluaron los hallazgos del método diagnóstico, los hallazgos intraoperatorios, y la evolución post operatoria. Resultados: El 85% de las pacientes presentó reflujo bilateral, y 15% reflujo unilateral. Más del 70% reportó presencia de dolor pélvico mayor a 6 meses, dispareunia, dismenorrea, y síntomas urinarios. Se demostraron diferencias estadísticamente significativas cuando se compararon los diámetros reportados en el dúplex, con los medidos intra operatoriamente, específicamente en las mediciones de la vena gonadal derecha, tanto en pacientes con reflujo unilateral (p=0.022) como bilateral (p= 0.017). El 92% de las pacientes presentó mejoría de los síntomas posterior al tratamiento quirúrgico. Conclusiones: La ligadura de las venas ováricas por cirugía abierta es una alternativa terapéutica para el tratamiento de las várices pélvicas, con resultados que demuestran mejoría sintomática importante. El dúplex constituye un método diagnóstico útil, aunque el diámetro de las venas gonadales puede ser subestimado.

Scalable real-time crisis mapping and analytics of social media streams for disaster management and breaking news

Real-time geoparsing of social media streams (e.g. Twitter, YouTube, Instagram, Flickr, FourSquare) is providing a new 'virtual sensor' capability to end users such as emergency response agencies (e.g. Tsunami early warning centres, Civil protection authorities) and news agencies (e.g. Deutsche Welle, BBC News). Challenges in this area include scaling up natural language processing (NLP) and information retrieval (IR) approaches to handle real-time traffic volumes, reducing false positives, creating real-time infographic displays useful for effective decision support and providing support for trust and credibility analysis using geosemantics. I will present in this seminar on-going work by the IT Innovation Centre over the last 4 years (TRIDEC and REVEAL FP7 projects) in building such systems, and highlights our research towards improving trustworthy and credible of crisis map displays and real-time analytics for trending topics and influential social networks during major news worthy events.

Utilidad de la relación estratégica comunitaria y el marketing como forma de perdurabilidad ante los procesos de reconstrucción social y económica

Grandes han sido los cambios que ha traído consigo la globalización, en donde el entorno empresarial se encuentra inmerso en constantes cambios, por tanto las empresas se ven obligadas a enfrenar entornos con alto grado de competitividad, en donde los clientes se han convertido en un bien escaso para la organización debido a la diversidad de ofertas presentes en el mercado y la manera del manejo de la información de los clientes. El presente trabajo expone las estrategias de marketing relacional, el cual ha tomado mayor relevancia debido a la insuficiencia del marketing transaccional para lograr la perdurabilidad empresarial, sin embargo se hace énfasis el concepto de comunidad debido a la dificultad de aplicar el marketing uno a uno con los clientes buscando un vínculo de largo plazo con el cliente, teniendo como contexto situaciones de reestructuración social de las crisis humanitarias.

Demasiado en serio : dos temas, una anécdota y un adiós.

Estudio de la relación entre los medios de comunicación y las matemáticas a través de diferentes situaciones. La noticia sobre el tsunami o una información económica en el País sirven para reflexionar sobre el papel de alfabetización que han de tener los medios.

Elevated marine deposits in Bermuda record a late Quaternary megatsunami

Deposits of coral-bearing, marine shell conglomerate exposed at elevations higher than 20 m above present-day mean sea level (MSL) in Bermuda and the Bahamas have previously been interpreted as relict intertidal deposits formed during marine isotope stage (MIS) I I, ca. 360-420 ka before present. On the strength of this evidence, a sea level highstand more than 20 m higher than present-day MSL was inferred for the MIS I I interglacial, despite a lack of clear supporting evidence in the oxygen-isotope records of deep-sea sediment cores. We have critically re-examined the elevated marine deposits in Bermuda, and find their geological setting, sedimentary relations, and microfaunal assemblages to be inconsistent with intertidal deposition over an extended period. Rather, these deposits, which comprise a poorly sorted mixture of reef, lagoon and shoreline sediments, appear to have been carried tens of meters inside karst caves, presumably by large waves, at some time earlier than ca. 310-360 ka before present (MIS 9-11). We hypothesize that these deposits are the result of a large tsunami during the mid-Pleistocene, in which Bermuda was impacted by a wave set that carried sediments from the surrounding reef platform and nearshore waters over the eolianite atoll. Likely causes for such a megatsunami are the flank collapse of an Atlantic island volcano, such as the roughly synchronous Julan or Orotava submarine landslides in the Canary Islands, or a giant submarine landslide on the Atlantic continental margin.

Our recent paper [McMurtry, G.M., Tappin, D.R., Sedwick, P.N., Wilkinson, I., Fietzkc, J. and Sellwood, B., 2007a. Elevated marine deposits in Bermuda record a late Quaternary megatsunami. Sedimentary Geol. 200, 155-165.] critically re-examined elevated marine deposits in Bermuda, and concluded that their geological setting, sedimentary relations, micropetrography and microfaunal assemblages were inconsistent with sustained intertidal deposition. Instead, we hypothesized that these deposits were the result of a large tsunami that impacted the Bermuda island platform during the mid-Pleistocene.

In our reply we answer the issues raised by Hearty and Olson [Hearty, P.J., and Olson, S.L., in press. Mega-highstand or megatsunami? Discussion of McMurtry et al.

Sedimentary Geol. 200,155-165.] and conclude that the Bermuda deposits do not provide unequivocal evidence of a prolonged +21 m eustatic sea level highstand. Rather, the sediments are more likely the result of a past megatsunami in the North Atlantic basin. (c) 2008 Elsevier B.V. All rights reserved.

Managing governance, risk and compliance for post-crisis regulatory change: a model of IS capabilities for financial organizations

The 2008-2009 financial crisis and related organizational and economic failures have meant that financial organizations are faced with a ‘tsunami’ of new regulatory obligations. This environment provides new managerial challenges as organizations are forced to engage in complex and costly remediation projects with short deadlines. Drawing from a longitudinal study conducted with nine financial institutions over twelve years, this paper identifies nine IS capabilities which underpin activities for managing regulatory themed governance, risk and compliance efforts. The research shows that many firms are now focused on meeting the Regulators’ deadlines at the expense of developing a strategic, enterprise-wide connected approach to compliance. Consequently, executives are in danger of implementing siloed compliance solutions within business functions. By evaluating the maturity of their IS capabilities which underpin regulatory adherence, managers have an opportunity to develop robust operational architectures and so are better positioned to face the challenges derived from shifting regulatory landscapes.

An exploratory study on how to improve the economy of American Samoa

Deep in the South Pacific region about 2,300 miles southwest of the Hawaiian islands1 lies a United States territory that many Americans have never heard of nor known anything about. However, some famous Americans such as Troy Polamalu of the Pittsburgh Steelers, semi retired professional wrestler Dwayne “The Rock” Johnson, and Hawaii Congresswoman Tulsi Gabbard have genealogical roots there. More importantly, many of the Territory’s sons and daughters have served and lost their lives for the United States flag and the cause of freedom around the world. This place is called American Samoa, a collection of seven islands that if glued together would have a total landmass of approximately 76 square miles, just a tad bigger than the capital city of the United States. According to the United States Census Bureau, there were 55,519 residents of American Samoa in 2010.1 The majority of them are ethnic Samoans, a Polynesian sect that traces its history back to early migrants from Southeast Asia who settled the islands around 1500 B.C.2 3 The climate is warm all year long and the forests along the mountains are ripe with vegetation. The main island is Tutuila with its beautiful and coveted landlocked harbor that was used as a coaling station by the United States naval ships during World War II. In fact, it was the Pago Pago Harbor that diminished the impact of the 2009 Tsunami that devastated the Samoan islands by channeling the waters of the Pacific Ocean towards the end of the harbor instead of flooding many other villages surrounding the Pago Pago Bay area. Lives and property were destroyed near the end of the Harbor but it could have been worse for the entire Bay area. Locally grown foods include coconut, taro, banana, guava, sugar cane, papaya, yam, pineapple, and breadfruit. It is completely surrounded by the Pacific Ocean from which the locals obtain a variety of seafood. There is a popular saying in Samoa that goes, “In Samoa, it is impossible to starve 1 American Samoa Department of Commerce, 2012 Statistical Yearbook, http://www.doc.as/wpcontent/uploads/2011/06/2012-Statistical-Yearbook-1.pdf 2 U.S. Census Bureau News, U.S. Census Bureau Releases 2010 Census Population Counts for American Samoa, http://www.census.gov/2010census/news/releases/operations/cb11-cn177.html (Aug. 24, 2011). 3 3 J. Robert Shaffer, American Samoa: 100 Years Under the United States Flag (Honolulu, Hawaii: Island Heritage Publishing, 2000), 34. 4 because people live off of the land’s and the ocean’s abundant resources.” To the west of American Samoa lies a larger group of four islands that make up the Sovereign State of Samoa, which became independent from New Zealand in 1962. Samoa and American Samoa share the same language, culture, and religion but are divided by government and political systems. The focus of this study will be on American Samoa, which became a United States territory in 1900 when the principal chiefs of Tutuila (the largest island in American Samoa) ceded the islands to the United States.

Influence of salivary glands extirpation on procreation in rats

The influence of extirpation of the submandibular and sublingual, parotid and all major salivary glands on pregnancy of rats was studied. The statistical analysis of the results indicated that there are statistically significant differences in the number of offsprings before and after extirpation of the salivary glands. The parotidectomized female rats presented the smallest number of offsprings as compared with other groups and presented some progressive sterility after the gland extirpation.
