Society and information economy have changed every aspect of our life in society: the economy, trade, business, industry, media, education, health, our entire culture. More than twenty years, Dr. Jerrold Maxmen2 said all medical functions may be performed in future by a team of paraprofessionals and computers: the clinical histories, physical examinations, laboratory tests, diagnoses, treatment and prognosis, and preventive functions, public health, research, education and health administration.The consequence is that doctors have less political power and consumers more opportunity to control the operation and structure of the health care system.

As the number of fungal pathogen outbreaks become more frequent worldwide across taxa, so have the number of species extirpations and communities persisting with the pathogen. This phenomenon raises questions, such as: “what leads to host extinction during an outbreak?” and “how are hosts persisting once the pathogen establishes?.” But the data on host populations and communities across life stages before and after pathogen arrival rarely exist to answer these questions. Over the past three to four decades, the amphibian-killing fungus Batrachochytrim dendrobatidis (Bd) spread in a wave-like manner across Central America, leading to rapid species extirpations and population declines. I collected data on tadpole and adult amphibians in El Copé, Panama before, during, and after the Bd outbreak to answer these questions. I used Bayesian statistical approaches to account for imperfect host and pathogen detection of marked and unmarked individuals. In the tadpole community, within 11 months of Bds arrival, density and occupancy rapidly declined. Species losses were phylogenetically correlated, with glass frogs disappearing first, and tree frogs and poison-dart frogs remaining. I found that tadpole communities resembled one another more strongly after the outbreak than they did before Bd invasion. I found no tadpoles within 22 months of the outbreak and limited signs of recovery within 10 years. In contrast, at the same site, for a population of male glass frogs, Espadarana prosopleon, I found that 10 years post-outbreak, the population was consistently half its historic abundance, and that the lack of recruits to the population explained why the population had not rebounded, rather than high pathogen-induced mortality. And finally, examining the entire amphibian community, I found high pathogen prevalence, low infection intensities, and high survival rates of uninfected and infected hosts. Bd transmission risk, i.e., the probability a susceptible host becomes infected, did not relate to host density, pathogen prevalence, or infection intensity– Bd transmission risk was uniform across the study area. My results are especially relevant to conservation biologists aiming to predict the future impacts of Bd outbreaks, those trying to manage persisting populations, and those interested in reintroducing species back into wild amphibian communities.

Resumen La crisis mundial de alimentos puso en evidencia la vulnerabilidad de los sistemas alimenticios, demostrando que el impacto más profundo se produce en los países con una mayor dependencia en la importación de alimentos y acompañados de mayores niveles de pobreza. En la región centroamericana, la crisis podría provocar un incremento del costo de la canasta básica alimentaria, un menor acceso a los alimentos, un aumento en la pobreza y en la inseguridad alimentaria y nutricional de la población más vulnerable. Abstract The international food crisis showed the vulnerability of the food supply system. The crisis exposed that the deepest shocks were produced in the countries with the major dependency in imports and highest levels of poverty. In the upcoming moths, the crisis could provoke an increase in the cost of the alimentary basic basket, a decrease in food access and an enlargement of poverty levels for the countries in Central America. In addition, the weakness on the sovereignty in the alimentary and nutritional security will provoke a major vulnerability in the population with the lowest income.

Objective: Our objective was to systematically review the published observational research related to the role of oxidative-nitrosative stress in pathogenesis of dengue. Methods: We searched electronic databases (PubMed, EMBASE, The COCHRANE library, ScienceDirect, Scopus, SciELO, LILACS via Virtual Health Library, Google Scholar) using the term: dengue, dengue virus, severe dengue, oxidative stress, nitrosative stress, antioxidants, oxidants, free radicals, oxidized lipid products, lipid peroxides, nitric oxide, and nitric oxide synthase. Articles were selected for review by title and abstract excluding letter, review, in vivo and in vitro studies, and duplicates studies. Selected articles were reviewed for study design, original purposes, sample size, main outcomes, methods, and oxidative-nitrosative stress markers values. Results: In total, 4,331 non-duplicates articles were identified from electronic databases searches, of which 16 were eligible for full text searching. Data from the observational studies originate from Asian countries (50%; 8/16), South American countries (31.2%; 5/16), and Central America and the Caribbean countries (18.8%; 3/16). Casecontrol study was the type of design most common in researches reviewed. The 1997 World Health Organization (WHO) dengue case classification criteria were used in all studies included in this review. Conclusions: Based on published data found in peer-reviewed literature, oxidative and nitrosative stress are demonstrated by changes in plasma levels of nitric oxide, antioxidants, lipid peroxidation and protein oxidation markers in patients with dengue infection. Additionally, elevated serum protein carbonyls and malondialdehyde levels appear to be associated with dengue disease severity.

Double Fortune is a novel relating events taking place in Miami, Central America, and The Bahama Bank in October and November, 1983. The main character, Michael Hayden, is a free-lance music producer who has become jaded and impotent. A chance encounter on the Bay with Marisol, a Salvadoran heiress, and Hector, her brother, propels him into a complex plot to expatriate money through U.S. government channels. Willy, a brooding Cuban bodyguard hired to protect and instruct the Salvadorans, emerges as both nemesis and key to the duplicities of the scheme. The final showdown involves the four of them on the water above the Cay Sal Bank, a part of the Bahamas equidistant to their disparate worlds.

Dengue fever is the most common cause of fever in travelers returning from the Caribbean, Central America, and South Central Asia.* Dengue infections are commonly reported from most tropical countries of the South Pacific, Asia, the Caribbean, the Americas, and Africa. This disease is caused by four similar viruses (DENV-1, -2, -3, and -4) and is spread through the bites of infected mosquitoes. For information on current outbreaks, consult CDC’s Travelers’ Health website (http://www.cdc.gov/travel). Dengue fever is a severe, flu-like illness that affects infants, young children and adults, but seldom causes death. Dengue should be suspected when a high fever (40°C/104°F) is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pains, nausea, vomiting, swollen glands or rash. Symptoms usually last for 2–7 days, after an incubation period of 4–10 days following the bite from an infected mosquito.

1. Sawfishes currently are among the most threatened elasmobranchs in the world. Only two species inhabit Atlantic waters: the largetooth sawfish (Pristis pristis) and the smalltooth sawfish (Pristis pectinata), both having suffered dramatic declines in their ranges. 2. The goal of this study was to evaluate the status of P. pristis in the Atlantic, and estimate local extinction risk based on historical and recent occurrence records. In order to accomplish these goals, a thorough search for historical and recent records of P. pristis in the Atlantic was conducted, by reviewing scientific and popular literature, museum specimens, and contacting regional scientists from the species’ historical range. 3. In total, 801 P. pristis records (1830–2009) document its occurrence in four major regions in the Atlantic: USA (n =41), Mexico and Central America (n =535), South America (n=162), and West Africa (n =48). Locality data were not available for 15 records. 4. Historical abundance centres were the Colorado-San Juan River system in Nicaragua and Costa Rica (and secondarily Lake Izabal of Guatemala), the Amazon estuary, and coastal Guinea-Bissau. 5. Currently, the species faces drastic depletion throughout its entire former range and centres of abundance. It appears to have been extirpated from several areas. The probability of extinction was highest in the USA, northern South America (Colombia to Guyane), and southern West Africa (Cameroon to Namibia). 6. Currently, the Amazon estuary appears to have the highest remaining abundance of P. pristis in the Atlantic, followed by the Colorado–San Juan River system in Nicaragua and Costa Rica and the Bissagos Archipelago in Guinea Bissau. Therefore the protection of these populations is crucial for the preservation and recovery of the species.

El siguiente estudio de caso analiza la influencia de la llegada de la migración infantil indocumentada centroamericana en la reformulación de la política migratoria de Estados Unidos en el período 2010-2014. Enfocándose en el caso de Honduras para dar a conocer y analizar las causas que crean las dinámicas migratorias por parte de los menores, este trabajo analiza como la llegada de estas poblaciones genera ciertos efectos en el proceso de toma de decisión de las políticas internas de los Estados Unidos. Por un lado, para resaltar las características del fenómeno migratorio, se utilizan las teorías de redes sociales y la teoría push and pull. Por otro, mediante los conceptos de Sensibilidad y Vulnerabilidad expuestos en la teoría de la Interdependencia Compleja de las Relaciones Internacionales, como también el concepto de Seguridad Societal propuesto por Barry Buzan se estudia el nivel de influencia del fenómeno infantil en el gobierno norteamericano.

El conflicto armado en Guatemala se originó por el abuso de poder, la desigualdad, la exclusión y la profunda discriminación, sobre todo hacia la población indígena, a la que se le han desconocido históricamente sus derechos y que fue la más afligida durante el conflicto. Lo que desembocó en el nacimiento de grupos al margen de la ley, cuyo propósito fue reivindicar los derechos de la población, así como la equidad y justicia social. El conflicto se caracterizó por la formación de grupos paramilitares, la violación al Derecho Internacional Humanitario, el elevado número de víctimas del conflicto, mayoritariamente indígenas y porque más del 85% de las violaciones a los derechos humanos fueron perpetradas por el Estado. Gracias a la voluntad política, al respaldo de la comunidad internacional, especialmente de la Organización de Naciones Unidas -ONU, y a los buenos oficios de la Comisión Nacional de Reconciliación – CNR, se lograron firmar los Acuerdos de Paz y dar fin a este cruento conflicto de más de 36 años. Las partes firmantes vieron la necesidad de que un ente autónomo e imparcial de Naciones Unidas, verificara el cumplimiento de La Misión de Naciones Unidas en Guatemala - MINUGUA contribuyó a la promoción, defensa y garantía de los derechos de la población indígena guatemalteca. Específicamente, incidió en el cumplimiento de los compromisos contenidos en el Acuerdo sobre Identidad y Derechos de los Pueblos Indígenas guatemaltecos –AIDPI, que fue suscrito el 31 de marzo de 1995, asimismo, contribuyó a la garantía del derecho a la justicia de la población indígena, lo que se evidenció en las acciones y el papel que desempeñó en los componentes de verdad, justicia y reparación.
