Renal volume of five-year-old preterm children are not different than full-term controls

Objective: In previous studies, smaller renal volumes were reported in prematurely born infants, however, these renal volumes were not corrected for body surface area, the main determinant of renal size. Given the rapid growth of the renal cortex after premature birth, the authors hypothesized that corrected volumes would not differ from healthy controls. Methods: Ambispective cohort study with prospective follow-up of prematurely born babies in a large specialized center and retrospectively recruited healthy control group. Children were assessed for renal length and renal volumes at age 5 by three independent ultrasonographers. Detailed anthropometry, blood pressure and renal function were also obtained. Age independent z-scores were calculated for all parameters and compared using descriptive statistics. Results: Eighty-nine premature study participants (median 32 weeks gestational age) and 33 healthy controls (median 38 weeks gestational age) were studied. Study participants did not differ in age, sex, Afro-Colombian descent, height, blood pressure, serum creatinine, or new Schwartz eGFR. Premature study participants had a significantly lower weight (17.65 ± 2.93 kg) than controls (19.05 ± 2.81 kg, p = 0.0072) and lower body surface area. The right renal volumes were significantly smaller (39.4 vs 43.4 mL), but after correction for body surface area, the renal volume and renal length z-scores were identical for both kidneys (mean right kidney -0.707 vs -0.507; mean left kidney -0.498 vs -0.524, respectively). Conclusion: Renal volumes need to be corrected to body surface area. After correction for body surface area, 5-year-old healthy and prematurely born children have comparable renal volumes

Reducing social vulnerability to environmental change : building trust through social collaboration on environmental monitoring

ABSTRACT: The occurrence of natural and socially driven catastrophic events has increased in the last few decades in response to global environmental changes. One of the most societally relevant challenges in managing the effects of these events is the establishment of risk management strategies that focus on managing vulnerability, particularly in disfavored countries, and communities among them. Most cases of enhanced vulnerability occur in, but are not limited to, developing countries, where the combination of social inequity, inappropriate use of natural resources, population displacement, and institutional mistrust, among other factors, make risk management particularly challenging. This paper presents a vulnerability-centered risk management framework based on social cohesion and integration principles that, combined with scientific, technical, and popular knowledge, lead to the development of social networks of risk reduction. This framework is intended as a strategy to strengthen early warning systems (EWS), where the human-related factor is among their most challenging components. Using water-related hazards as a case study, this paper describes the experience of the conformation of a social network for environmental monitoring using this model example on vulnerability reduction in the rural areas of the central Andes in Colombia. This experience allowed the effective conformation of a social network for environmental monitoring in 80 municipalities of Colombia, where communities developed a sense of ownership with the instrumentation and the network, strengthening links with local authorities and contributing to more efficient EWS. More generally, the authors highlight the need to develop vulnerability-centered risk management via community-building strategies, particularly for areas where little can be done to decrease the occurrence of catastrophic events

Laboratorios de innovación social, como estrategia para el fortalecimiento de la participación ciudadana

The present article approaches elements of the design of a laboratory of social innovation from the Faculty of Social Sciences of the Greater School of Antioquia in the city of Medellín - Colombia, with the purpose of generating a space that promotes the cocreación to solve social problems, by means of the application of innovation and technology processes for social appropriation, which allows connecting, more and more, the university with the community, where the strategies of university practices, extension and social projection, and civil society converge. The focus of the research is qualitative and contemplates a phenomenological design with interview techniques with alternative didactic approaches such as Participation Action Research. As a result, the most representative elements of the bibliographic review carried out on the social innovation laboratory are presented, as well as the interviews and panels with experts carried out, which show the importance that these spaces take in the development of the communities, starting from Public efforts calling them citizen laboratories or public innovation, promoting the strengthening of collaboration networks between different agents of society. It concludes with the importance of initiating the pilot test in a Higher Education Institution.El presente artículo aborda elementos del diseño de un laboratorio de innovación social desde la Facultad de Ciencias Sociales del Colegio Mayor de Antioquia en la ciudad de Medellín - Colombia, con el propósito de generar un espacio que promueva la cocreación para resolver problemas sociales, mediante la aplicación de procesos de innovación y tecnología para la apropiación social, que permita conectar, cada vez más, la universidad con la comunidad, donde confluyan las estrategias de prácticas universitarias, extensión y proyección social, y la sociedad civil. El enfoque de la investigación es cualitativo y contempla un diseño fenomenológico con técnicas de entrevistas con enfoques didácticos alternos como la Investigación Acción Participación. Como resultado se presentan los elementos más representativos de la revisión bibliográfica realizada sobre laboratorio de innovación social, al igual que las entrevistas y paneles con expertos realizadas, donde se evidencia la importancia que van tomando estos espacios en el desarrollo de las comunidades, a partir de esfuerzos de carácter público llamándolos laboratorios ciudadanos o de innovación pública, promoviendo el fortalecimiento de redes de colaboración entre los diferentes agentes de la sociedad. Se concluye con la importancia de iniciar la prueba piloto en una Institución de Educación Superior

Derecho laboral individual colombiano

El presente texto, precisamente, recoge a manera de compendio, el trabajo de reconocidos docentes, abogados litigantes y asesores, jueces y magistrados, que dirigidos por el profesor Ignacio Cadavid Gómez, entregan a la comunidad jurídica nacional su visión de un derecho laboral renovado, pujante y de innegable valor, no solo por la vigencia que aún conserva la especialidad, en tanto se trata de una que cobija y regula el diario vivir de gran parte de los habitantes del país, según la perspectiva que se mire, -bien de trabajadores, ora de empleadores-, sino porque el enriquecimiento jurisprudencial del que ha sido objeto en los últimos tiempos la convierte en necesaria tanto para extraños como para estudiosos de la misma

Naturaleza urbana. Plataforma de experiencias

Naturaleza Urbana presenta experiencias autogestionadas que, con el tiempo, se han posicionado como ejercicios alternativos de identificación, monitoreo y recuperación de la biodiversidad urbana. En otros casos, el modelo comunidad-gobierno ha permitido desarrollar diagnósticos y propuestas de gestión corresponsables y sistémicas, entendiendo por esto último iniciativas que nacen desde los valores mismos que cada comunidad le atribuye a su biodiversidad. Del mismo modo, se presentan esfuerzos gubernamentales que han enriquecido la visión ambiental de los principales instrumentos de planificación urbana, por ejemplo, integrando la condición propiamente urbana como oportunidad para aumentar la oferta ambiental de la ciudad, fortaleciendo las funciones y procesos de la biodiversidad y revitalizando, con ello, la calidad de vida del entorno urbano. Por su parte, las universidades y los centros de investigación se han sumado a la ola emergente de generación de conocimiento en biodiversidad urbana (fenómeno nacional e internacional), han brindado evidencia científica de su valor para el bienestar humano y han propuesto reflexiones y lineamientos cualitativos de biodiversidad, con miras a hacer del ordenamiento un ejercicio más coherente con cada contexto territorial en particular.Bogotá, D.

Urban Nature

Preservation, restoration, monitoring of biodiversity and promotion of native species, in their strict and classical sense, could be unviable strategies in the cities. Management systems such as the protected areas acquire profoundly different connotations and objectives from the traditional ones when thought of in the context of a city. Similarly, although ecological restoration seeks to return to a baseline ecosystem, there is little that we know about the vegetation present on the urban borders of the main Colombian cities prior to the 20th century. Finally, the models for potential distribution of species could produce unreliable results, because their methodological bases were not conceived based on urban dynamics. In this context, to de ne urban biodiversity and what strategy must be applied for its conservation implies a challenge that, beyond being scienti c, is necessarily social and cultural and involves planning and design. Innovation is inevitable.Bogotá, D. C
