Estudio geoambiental de la cuenca de Guanabo, Cuba : aproximación a la problemática del agua
El diagnostico de los recursos ambientales incluidos los hidrológicos, de un país, región o cuenca, es una tarea de primer orden, dada la importancia que tienen para el desarrollo socio-económico, especialmente en los momentos actuales donde se relaciona tanto determinados déficits ambientales como la propia crisis del agua, con las consecuencias directas del cambio global.
En Cuba, el manejo de cuencas puede dividirse en dos grandes etapas: la primera que comprende el período 1960–1985 que se caracterizó por un Manejo Sectorial especialmente dirigido hacia los sectores de los recursos hídricos, los recursos agroforestales y a la agricultura extensiva. La segunda etapa, comprende el período 1986–2004, donde, sin abandonar el manejo sectorial, se hace notar con más fuerza el llamado Manejo Integral, teniendo en la dimensión medioambiental el principal acicate. Unida a la variable pluviometría, hay una diversa disponibilidad temporal del recurso agua, y pese a las obras hidráulicas construidas para suplir su déficit, no ha podido evitarse que en muchas zonas del país existan en los últimos años dificultades de abastecimiento. La ocurrencia de años con lluvias inferiores a la media histórica, unido a su mal aprovechamiento, crean condiciones perjudiciales para la sociedad, la economía y el medio ambiente.
Bajo estos planteamientos, el objetivo del presente artículo es analizar las características geoambientales con especial interés en la problemática del agua en una zona especialmente sensible como es la cuenca de Guanabo, situada entre La Habana y el polo turístico de Varadero.Diagnosis of environmental resources including hydrological, for a country, region or watershed, is a major task, given the importance that have socio-economic development, especially at the present time which relates both certain environmental deficits and own crisis of water, with the direct consequences of global change.
In Cuba, watershed management can be divided into two major stages: the first covering the period 1960-1985 was characterized by a particularly directed towards sectors of water resources, extensive agriculture and forestry resources sectorial management. The second stage covers the period 1986-2004, where, without abandoning the sectorial management, it is noted more forcefully the so-called comprehensive management, taking the main spur on the environmental dimension.
Coupled with variable rainfall, there is a diverse temporary availability of the resource water, and despite built to meet its deficit hydraulic works, not have been avoided exist in recent years supply problems in many areas of the country.
The occurrence of years below the historical average rainfall coupled with bad use, created conditions harmful to society, the economy and the environment.
Under these approaches, this article aims to analyze characteristics geoambientales with special interest in the problems of water into a sensitive area as it is basin Guanabo, situated between Cuba and the tourist pole of Varadero
La carga etiquetante en el migrante venezolano en Ecuador. Un estudio comparado entre el procesamiento judicial y la matriz mediática
El presente artículo evalúa los procesos de estigmatización asociables a la inseguridad ciudadana de la población migrante venezolana en Ecuador y su relación con la peligrosidad real, medible mediante procedimientos estandarizados hasta la fecha. Para lograr esto, a) se diserta acerca de los peligros asociables a la estigmatización, según el contexto jurídico ecuatoriano e internacional, b) se comparan los procedimientos de medición de peligrosidad de esta población en Lima, Chile y Colombia, c) se utiliza el método establecido por el Migration Policy Institute, consistente en comparar la proporción de la población migrante según la población nativa receptora, con la población migrante privada de libertad según la población nativa receptora privada de libertad y, finalmente, d) se describen los discursos estigmatizantes mediante encuestas realizadas previamente, e) se comparan los resultados con un estudio cuanticualitativo de tipo etnográfico en un territorio altamente conflictivo del país. Se concluye que la peligrosidad de los migrantes venezolanos es muy inferior a la peligrosidad de la población receptora y colombiana y, además, no corresponde a las proporciones de percepción de inseguridad que se tiene de esa población. Se diserta sobre los problemas que la estigmatización puede generar en la sociedad ecuatoriana.
PALABRAS CLAVE: Estigmatización; migración venezolana; Ecuador; personas privadas de libertad; inseguridad ciudadana.
The labeling burden on the Venezuelan migrant in Ecuador. A comparative study between judicial prosecution and the media matrix
ABSTRACT
This article evaluates the labeling processes associated with citizen insecurity of the Venezuelan migrant population in Ecuador, and its relationship with real danger, measurable through standardized procedures to date. To achieve this, a) We discuss the dangers associated with labeling, according to the Ecuadorian and international legal context; b) We compared the procedures for measuring dangerousness of this population in Lima, Chile and Colombia; c) We used the method established by the Migration Policy Institute, consisting of comparing the proportion of the migrant population according to the receiving native population, and the migrant population deprived of liberty according to the receiving native population deprived of liberty; finally, d) We contrast the labeling discourses through surveys previously carried out, e) We compared the numeric results against a quantitative-qualitative study of an ethnographic type in a highly conflictive territory of the country. It is concluded that the danger of Venezuelan migrants is much lower than the danger of the receiving and Colombian population and, furthermore, it does not correspond to the proportions of perception of insecurity that this population has. We disserted on the problems that labeling can generate in Ecuadorian society.
KEYWORDS: Labeling, Venezuelan migration; Ecuador; people deprived of liberty; citizen insecurity

Structure-based design of a Cortistatin analogue with immunomodulatory activity in models of inflammatory bowel disease
Ulcerative colitis and Crohn’s disease are forms of inflammatory bowel disease whose incidence and prevalence are increasing worldwide. These diseases lead to chronic inflammation of the gastrointestinal tract as a result of an abnormal response of the immune system. Recent studies positioned Cortistatin, which shows low stability in plasma, as a candidate for IBD treatment. Here, using NMR structural information, we design five Cortistatin analogues adopting selected native Cortistatin conformations in solution. One of them, A5, preserves the anti-inflammatory and immunomodulatory activities of Cortistatin in vitro and in mouse models of the disease. Additionally, A5 displays an increased half-life in serum and a unique receptor binding profile, thereby overcoming the limitations of the native Cortistatin as a therapeutic agent. This study provides an efficient approach to the rational design of Cortistatin analogues and opens up new possibilities for the treatment of patients that fail to respond to other therapies.A.Rol was a recipient of a PhD fellowship from the Generalitat de Catalunya (FI) and A.E. and E.P. were recipients of PhD fellowships granted by the Severo Ochoa Program(FPI).

Decision-Making about COVID-19 Vaccines among Health Care Workers and Their Adolescent Children
Health care workers promote COVID-19 vaccination for adolescent patients, and as parents, may influence their own children to get vaccinated. We conducted virtual, semi-structured qualitative interviews with vaccinated health care workers and their adolescent children to explore their decision-making process for COVID-19 vaccination. In total, 21 health care workers (physicians, nurses, and medical staff) and their adolescent children (N = 17) participated in interviews. The following three themes described parent-adolescent decision-making for COVID-19 vaccination: (1) family anticipation and hesitation about COVID-19 vaccine approval; (2) parents’ or adolescents’ choice: the decision maker for adolescent COVID-19 vaccination; and (3) leveraging one’s vaccination status to encourage others to get vaccinated. Nurses encouraged adolescent autonomy in decisions for COVID-19 vaccination while physicians viewed vaccination as the parent’s decision. Health care workers and their adolescent children used role-modeling to motivate unvaccinated peers and may model their decision-making process for adolescent COVID-19 vaccination with their own children to support their patients’ and parents’ vaccine decisions
Use of colonoscopy as a primary screening test for colorectal cancer in average risk people
The use of colonoscopy as a primary screening test for colorectal
cancer (CRC) in average risk adults is a subject of controversy. Our primary
objective was to build a predictive model based on a few simple variables that
could be used as a guide for identifying average risk adults more suitable for
examination with colonoscopy as a primary screening test. METHODS: The prevalence
of advanced adenomas was assessed by primary screening colonoscopy in 2210
consecutive adults at least 40 yr old, without known risk factors for CRC. Age,
gender, and clinical and biochemical data were compared among people without
adenomas, those with non-advanced adenomas, and those with any advanced neoplasm.
A combined score to assess the risk of advanced adenomas was built with the
variables selected by multiple logistic regression analysis. RESULTS: Neoplastic
lesions were found in 617 subjects (27.9%), including 259 with at least one
neoplasm that was 10 mm or larger, villous, or with moderate-to-severe dysplasia,
and 11 with invasive cancers. Advanced lesions were more frequent among men,
older people, and those with a higher body mass index (BMI). These three
variables were independent predictors of advanced adenomas in multivariate
analysis. A score combining age, sex, and BMI was developed as a guide for
identifying individuals more suitable for screening colonoscopy. CONCLUSIONS:
Age, gender, and BMI can be used to build a simple score to select those average
risk adults who might be candidates for primary screening colonoscop
