Abstract: Uno de los grandes logros de la salud pública mundial, la erradicación de la viruela, puede verse mermado por el posible riesgo de bioterrorismo. El debate acerca de la destrucción de los restos del virus en los dos laboratorios de referencia de la Organización Mundial de la Salud ha cambiado diametralmente debido a los eventos terroristas y a la dispersión intencional de Bacillus anthracis ocurridos en poblaciones civiles en Estados Unidos de América en el a o 2001. La liberación del virus Variola con fines terroristas constituye un riesgo mínimo no cuantificable, pero desafortunadamente real. El impacto podría ser devastador debido a la elevada morbimortalidad de la enfermedad aunada al pánico y a la desestabilización social que podría ocasionar. Es por ello que el establecimiento de un plan de respuesta, sumado a disponibilidad de vacuna para ser utilizada pos-exposición, es importante dentro de los planes de contingencia contra el bioterrorismo. El reiniciar un programa limitado de vacunación contra la viruela, como parte de dicho plan, ha sido recientemente recomendado por el Comité Asesor de Vacunación, del Centro para el Control de las Enfermedades, pero la vacuna disponible puede causar complicaciones graves e incluso la muerte, por lo que dicha recomendación no ha sido universalmente aceptada. No obstante, el personal médico y de salud pública requiere de información actualizada sobre la viruela y su prevención, ya que ellos son la primera línea de defensa en caso de un posible brote a consecuencia de un ataque bioterrorista. El presente artículo presenta una revisión dirigida a proporcionar al personal de salud un enfoque clínico, epidemiológico y preventivo sobre la viruela.

Abstract: the worldwide eradication of smallpox, a major achievement in public health, is currently threatened by the risk of bioterrorism. the debate on the destruction of the variola virus in the two reference laboratories of the world health organization has dramatically switched to the preservation of the remaining virus after the september 2001 terrorist events in the u.s. along with the intentional release of bacillus anthracis in the u.s. the risk of intentional release of variola virus constitutes a minimal, yet possible risk. a smallpox epidemic could have a devastating impact due to its elevated morbidity and mortality that would inflict in non-immune human population, in addition to the ensuing panic and social unrest. therefore, the development of national preparedness and response plans along with the availability of smallpox vaccine to be used in the post-exposure phase represent a fundamental part of the preventive efforts to cope with bioterrorism. reestablishing a preventive vaccination program was recently recommended by the advisory committee on immunization practices (acip). however, the vaccine currently available has historically been associated with serious adverse reactions, even death. thus, this recommendation has not been universally accepted. to counter an epidemic of smallpox, medical personnel in the frontline need to be prepared with updated smallpox infor mation to identify, diagnose, isolate, and treat cases if a bioterrorist attack should occur. herein we present an in-depth review for health care personnel with relevant epidemiologic, clinical, and preventive information on smallpox.

Abstract: in early february 2003, the world health organization (who) began receiving reports of patients with a syndrome characterized by an atypical pneumonia with rapid progression to respiratory failure without an identified cause despite extensive diagnostic workups. most of these reports pointed out that the outbreak started in southern china, specifically in the guandong province. the initial outbreak in south east asia has already spread to other regions in asia, europe, north and south america, and south africa. many of these cases can be linked through chains of transmission to an index case from the guandong province who visited hong kong. although the exact mode of transmission has not been clearly established, the etiology of this syndrome has already been identified. a novel coronavirus has been identified by electron microscopy and molecular assays in multiple laboratories from respiratory specimens throughout the world. the syndrome has been defined as sars (severe acute respiratory syndrome) by who, and is characterized by an incubation period between 1 and 10 days (average 5 days) and by a febrile phase that usually lasts approximately 3 days. during the respiratory phase that begins around day 3, patients start developing a dry cough, shortness of breath and hypoxemia. mechanical ventilatory support is required in about 10 to 40% of cases and the case-fatality rate ranges between 3 and 16%. the laboratory findings in sars cases include leukopenia, thrombocytopenia, and a rise in transaminases and lactic dehydrogenase levels. treatment of sars includes supportive measures and the empiric use of ribavirin. respiratory isolation, use of respiratory masks, and compulsory hand hygiene constitute the principal preventive measures. the confirmation of a case can be performed at reference laboratories by serologic and molecular assays. from the onset of this epidemic mexico established a surveillance system as well as clinical guidelines and recommendations for the

Abstract: the assemblage of arthropods and helminths, present in sigmodontine rodents (cricetidae) from a broad wetland area of the río de la plata, argentina, was studied. a total of 250 sigmodontines were captured during a two-year sampling period: scapteromys aquaticus and oxymycterus rufus were the most abundant hosts, followed by oligoryzomys nigripes, akodon azarae, oligoryzomys flavescens, and deltamys kempi. there were 33102 parasites collected, corresponding with rhopalopsyllidae fleas (siphonaptera), hoplopleuridae lice (phtiraptera), laelapidae and macronyssidae mites, ixodidae ticks, and trombiculidae chiggers (acari), the trematodes echinostomidae, microphallidae, and dicrocoelidae, the flatworm ciclophyllidea, the nematods trichuridae, spiruridae, onchocercidae, physalopteridae, aspidoderidae, oxyuridae, and nippostrongylinae, and the thorny-headed worm acanthocephala. a list of arthropods and helminths species associated with each rodent species was given, as well as the prevalence and mean abundance. new host and geographic records were provided. the phenogram of the relationships of the parasite assemblages showed a high value of similarity between both species of oligoryzomys, and between s. aquaticus and o. rufus. variation of the values observed in the prevalence and the mean abundance of the host-parasite association suggests that there could be environmental barriers between the rodent populations, or that differential behavior of the host species (i.e. use of microhabitats, tropics behaviors) may influence these indexes. this knowledge may be used to determine targets for biological conservation and ecological impact of parasitism in the area.

Abstract: Mesoamerica and the Caribbean are low-latitude regions at risk for the effects of climate change. Global climate models provide large-scale assessment of climate drivers, but, at a horizontal resolution of 100 km, cannot resolve the effects of topography and land use as they impact the local temperature and precipitation that are keys to climate impacts. We developed a robust dynamical downscaling strategy that used the WRF regional climate model to downscale at 4 - 12 km resolution GCM results. Model verification demonstrates the need for such resolution of topography in order to properly simulate temperatures. Precipitation is more difficult to evaluate, being highly variable in time and space. Overall, a 36 km resolution is inadequate; 12 km appears reasonable, especially in regions of low topography, but the 4 km resolution provides the best match with observations. This represents a tradeoff between model resolution and the computational effort needed to make simulations. A key goal is to provide climate change specialists in each country with the information they need to evaluate possible future climate change impacts.

Abstract: the germination speed and seedling growth of maize seed of two different sizes was evaluated. to determine the differences in the biomass production during the vegetative stage from different seed size, considering the effects of humidity on seedling physiological status. a larger amount of biomass in endosperm and embryo allowed greater availability of reserves during the later stage of the germination; previous to emergency resulting in a high seedling vigor and a most accumulation of as much radical biomass as aerial during the vegetative stage, the water restriction during the germination and the vegetative stage of these plants caused a decrement of 72,6% in the aerial biomass accumulation in big and small seed plants, due to a diminution from diverse physiological processes such as stomatic conductance, transpiration and photosynthetic rate.

Características de las formas de gestión del hábitat por las organizaciones populares urbanas
Frías, Carlos
Bulletin de l'Institut Francais d'études Andines , 1988,
Abstract: Le thème de recherche ici proposé et qui a été mis en relief par l′action des habitants eux-mêmes, est celui de la gestion populaire de l'habitat. La crise économique n'a pas seulement fait surgir de nouveaux types d'organisation, mais également de nouvelles perspectives de traitement de nouveaux besoins et revendications. Il importe donc d'affiner les concepts et de produire des synthèses de travaux réalisés à ce jour sur le sujet. Cet article propose une définition provisoire de ce que l'on pourrait appeler 'gestion populaire de l'habitat' et une analyse de ses principales caractéristiques, en insistant sur sa tendance à reproduire des modèles déjà connus, son ouverture sur les innovations techniques et organisatives, et la croissante spécialisation des organisations. L'analyse porte également sur l'importance de l'organisation dans l'ensemble du processus, ainsi que sur le faible poids politique qu'elle représente encore dans le cadre de l'action sur l'ensemble de la ville. La gestión popular del hábitat, producto de la propia acción de los pobladores, ha sido propuesta como un tema relevante a ser investigado. Con la crisis económica no sólo surgen nuevas organizaciones, también nuevas necesidades y reivindicaciones encuentran su espacio de solución. Se hace necesario afinar los conceptos y producir algunas síntesis de los trabajos que sobre el tema se han realizado. El presente artículo propone una definición provisional de lo que se puede entender por gestión popular del hábitat y una sistematización de las principales características de la misma, haciendo énfasis en su tendencia a repetir modelos conocidos, su apertura a las innovaciones técnicas y organizativas, y la especialización de las organizaciones en ámbitos específicos de gestión. Se analiza también la importancia de la organización en todo este proceso así como el aún escaso alcance político de su acción sobre el conjunto de la ciudad. Popular self-management, by the own residents, of their living environment has been proposed as an important theme for investigation. With economic crisis, not only do new organizations appear, but they are accompanied by necessities and demands for resolution. This makes it necessary to refine our concepts and to attempt a synthesis of previous studies treating this subject. This article proposes a provisional definition of the 'popular self-management of the living environment', and a systematization of its principal characteristics. It emphasizes the tendency of this management to follow known patterns, the degree of its openness to technical and organ

Abstract: Using reasonableness, we examine the U.S. Catholic bishops’ opposition to provisions of the Affordable Care Act of 2010. Weaving contributions from theology, philosophy, and jurisprudence, we emphasize the reasonable importance of mental health therapy for women within a relevant Catholic/Christian dialogue, particularly in the wake of the U.S. Supreme Court’s decision on healthcare. We principally identify socially imbedded factors that contribute to ending unwanted pregnancies, and argue that freedom of conscience is indeed freedom of choice within which women’s reproductive needs lie under protections of the U.S. Constitution. We recognize that Catholic tradition originates in the words and behaviors of Jesus. Examining closely these actions toward women, we find no reasonable justification for the bishops’ position against women’s freedom of conscience. We also discovered that revelation does not belong exclusively to the bishops; truth continues to be revealed to all human consciences, and true freedom does not allow for coercion/castigation of dogmatic import. We advocate for women’s ability to openly discuss their struggles to meet their reproductive condundra and to deconstruct their sexual stereotypes in mental health therapy. We provide crucial recommendations to augment choices for women’s reproduction condundra, and incite the need for new epistemic frameworks to address the complexity of female sexuality.
