Introducción: La preeclampsia severa es una de las principales patologías que afectan a las mujeres embarazadas, sus complicaciones tienen un alto impacto en la salud del binomio madre-hijo. Materiales y métodos: Se realizo una serie de casos, durante un periodo de 1 año se revisaron las historias clínicas de las pacientes que ingresaron a la unidad de cuidado intensivo obstétrico de la Clínica Orquídeas, con diagnóstico de preeclampsia severa. Se describieron los datos demográficos y las complicaciones. Se realizó análisis univariado con las variables de interés y se calcularon diferencias significativas por medio del test exacto de Fisher. Resultados: Se registraron 196 pacientes con preeclampsia severa en el periodo de estudio. Las complicaciones mas frecuentes fueron síndrome HELLP (30,6%), insuficiencia renal aguda (16,3%) y edema pulmonar (10,2%); el ingreso de las pacientes con preeclampsia severa a la UCIO en embarazo aumenta el riesgo de sufrir complicaciones. El síndrome de HELLP se presento con mayor frecuencia en pacientes que realizaron 6 o mas controles prenatales (p=0.066). Discusión: Los resultados evidencian una prevalencia de preeclampsia severa mayor que la observada por otros autores, probablemente por ser una UCI exclusivamente obstétrica. Las complicaciones mas frecuentes son concordantes con otros estudios publicados. El mayor riesgo de complicaciones asociadas en pacientes que ingresan embarazadas a la UCIO podría estar en relación a la severidad de la patología. Se requieren estudios analíticos para establecer asociaciones entre cada una de las complicaciones y sus factores condicionantes.

El comportamiento biológico de las células cancerosas es influenciado por el microambiente en el que se desarrollan y en este, factores como la angiogénesis o el estímulo de agentes estresores como la hipoxia, se han considerado críticos para su evolución y manejo terapéutico. Uno de los mecanismos moleculares implicados en la respuesta celular frente a estímulos estresores es la activación de vías de señalización intracelulares; en este estudio, se evaluó el estado de la vía JAK/STAT y en ella la expresión/activación de la proteína STAT3 en la línea tumoral (HeLa) y endotelial (EA.hy926), sometidas a hipoxia física y química con mesilato de deferoxamina durante 2, 6 y 24 horas. Adicionalmente, al considerar la importancia de la hipoxia como un agente modificador de la respuesta en el manejo del cáncer utilizando radiaciones ionizantes, se construyeron curvas de supervivencia celular que permitieron evaluar el comportamiento celular frente a estos estímulos. El presente estudio resalta la importancia de la hipoxia como un estímulo que modifica la activación de la proteína STAT3 y la supervivencia de células irradiadas en las dos líneas estudiadas.

En el contexto de globalización, cambio y entornos más agresivos para las organizaciones, se hace necesario conocer el impacto de la administración de la cadena de suministro en el desempeño organizacional y cómo el fortalecimiento de la cadena permite a las organizaciones mantenerse en el mercado (Jacoby, 2009). Esta tendencia aplica para las organizaciones en todo el mundo, en el caso de las organizaciones Colombianas se requiere un trabajo académico donde se haga un análisis de los impactos de las cadenas de suministro en el desempeño organizacional (Ministerio de Transporte, Ministerio de Comercio, DIAN, & DNP, 2008). Una muestra de lo anterior es el hecho de que Colombia se encuentra en el puesto 97 en el ranking de desempeño logístico hecho por el Banco Mundial en 2014 (Banco Mundial, 2014). Esto demuestra la necesidad de mejorar los procesos logísticos en el pas mediante el fortalecimiento de las cadenas de suministros, permitiendo una mayor eficiencia y capacidad de respuesta ante las demandas globales de los diferentes mercados en un entorno cambiante y agresivo. Por lo anterior se debe comprender y dimensionar el potencial impacto que tenga el desempeño organizacional y la correcta gestión de la cadena de suministros en el contexto Colombiano. Por consiguiente a través de una exhaustiva revisión literaria se buscaran los puntos de convergencia entre el desempeño organizacional y la cadena de suministros, haciendo uso del modelo Balance Score Card para analizar desde las perspectivas financiera, clientes, procesos internos e innovación y aprendizaje de las organizaciones, las actividades que involucran las cadena de suministro: aprovisionamiento, producción y distribución.

Esta investigación se centra en la Fédération Internationale de Football Association (FIFA) como organización política. Intenta responder dos interrogantes primordiales: 1) ¿cómo la FIFA ha constituido el poder que tiene actualmente y, así, hacerse del monopolio indiscutido del fútbol? Y 2) ¿cómo ha cambiado en el tiempo la política interna de FIFA y su vínculo con la política internacional? Para lograr esto, se realiza un estudio histórico, basado principalmente en documentos, que intenta caracterizar y analizar los cambios de la organización en el tiempo. Se enfatizan las últimas dos presidencias de FIFA, de João Havelange y Joseph Blatter, como casos de estudio.

Bullous pemphigoid (BP) is the most common autoimmune subepidermal bullous disease typically affecting the elderly. Although different therapeutic regimens have been proposed, a review of the evidence is needed to aid clinicians in their decision making and management. Systemic therapies such as corticosteroids and adjuvants are effective in BP but are plagued with adverse effects, and potent topical steroids are an alternative treatment. This article reviews the evidence supporting different therapeutic options in the management of BP.

CONTEXT Chemical eye injuries are ophthalmological emergencies with a high risk of secondary complications and severe visual loss. Only limited epidemiological data for such injuries are available for many countries. PATIENTS AND METHODS We performed two independent studies. The cause of chemical eye injuries was assessed with a prospective questionnaire study. Questionnaires were sent to all ophthalmologists in Switzerland. A total of 163 patients (205 eyes) were included, between December 2012 and October 2014. Independent of the questionnaire study, the incidence of chemical eye injuries was assessed with a retrospective cohort study design using the database of the mandatory accident insurance. RESULTS Ophthalmological questionnaires revealed that plaster/cement (20.5%), alkaline (12.2%) and acid (10.2%) solutions caused the highest number of chemical injuries. Only 2% of all injuries were classified as grade III and none as grade IV (Roper-Hall classification). The official toxicological information phone-hotline was contacted in 4.3% of cases. Using data from the accident insurance, an incidence of chemical eye injuries of about 50/100 000/year was found in the working population. CONCLUSION Here, we present data on the involved agents of chemical eye injuries in Switzerland, and also the incidence of such injuries in the working population. This may also help to assess the need for further education programs and to improve and direct preventive measures.

IBPOWER is a Project awarded under the 7th European Framework Programme that aims to advance research on intermediate band solar cells (IBSCs). These are solar cells conceived to absorb below bandgap energy photons by means of an electronic energy band that is located within the semiconductor bandgap, whilst producing photocurrent with output voltage still limited by the total semiconductor bandgap. IBPOWER employs two basic strategies for implementing the IBSC concept. The first is based on the use of quantum dots, the IB arising from the confined energy levels of the electrons in the dots. Quantum dots have led to devices that demonstrate the physical operation principles of the IB concept and have allowed identification of the problems to be solved to achieve actual high efficiencies. The second approach is based on the creation of bulk intermediate band materials by the insertion of an appropriate impurity into a bulk semiconductor. Under this approach it is expected that, when inserted at high densities, these impurities will find it difficult to capture electrons by producing a breathing mode and will cease behaving as non-radiative recombination centres. Towards this end the following systems are being investigated: a) Mn: In1-xGax N; b) transition metals in GaAs and c) thin films.

The volumes contain student notes on a course of medical lectures given by Dr. Benjamin Rush (1746-1813) while he was Professor of the Institutes of Medicine and Clinical Practice at the University of Pennsylvania Medical School, likely in circa 1800-1813. The notes indicate Rush often referenced the works or teachings of contemporaries such as Scottish physicians William Cullen, John Brown, John Gregory, and Robert Whytt, and Dutch physician Herman Boerhaave. He frequently included anecdotes and case histories of his own patients, as well as those of other doctors, to illustrate his lecture topics. He also advised students to take notes on the lectures after they ended to allow them to focus on what they were hearing. Volume 1 includes notes on: physician conduct during visits to patients; human and animal physiology; voice and speech; the nervous system; the five senses; and faculties of the mind. Volume 2 includes notes on: food, the sources of appetite and thirst, and digestion; the lymphatic system; secretions; excretions; theories of nutrition; differences in the minds and bodies of women and men; reproduction; pathology; a table outlining the stages of disease production; “disease and the origin of moral and natural evil”; contagions; the role of food, drink, and clothing in producing disease; worms; hereditary diseases; predisposition to diseases; proximate causes of diseases; and pulmonary conditions. Volume 3 includes notes on: the pulse; therapeutics, such as emetics, sedatives, and digitalis, and treatment of various illnesses like pulmonary consumption, kidney disease, palsy, and rheumatism; diagnosis and prognosis of fever; treatment of intermitting fever; and epidemics including plague, smallpox, and yellow fever, with an emphasis on the yellow fever outbreaks in Philadelphia in 1793 and 1797.
