Visual acuity and contrast sensitivity in preterm and full-term children using a novel digital test

Visual assessment in preverbal children mostly relies on the preferential looking paradigm. It requires an experienced observer to interpret the child’s responses to a stimulus. DIVE (Device for an Integral Visual Examination) is a digital tool with an integrated eye tracker (ET) that lifts this requirement and automatizes this process. The aim of our study was to assess the development of two visual functions, visual acuity (VA) and contrast sensitivity (CS), with DIVE, in a large sample of children from 6 months to 14 years (y) of age, and to compare the results of preterm and full-term children. Participants were recruited in clinical settings from five countries. There were 2208 children tested, 609 of them were born preterm. Both VA and CS improved throughout childhood, with the maximum increase during the first 5 years of age. Gestational age, refractive error and age had an impact on VA results, while CS values were only influenced by age. With this study we report normative reference outcomes for VA and CS throughout childhood and validate the DIVE tests as a useful tool to measure basic visual functions in children

Actualización e innovación educativa digital para la enseñanza en el siglo XXI

This article has been developed in order to respond to the need to implement an improvement of processes and procedures within the teaching of 24 beneficiaries of the Eugenio Espejo Educational’s Unit due to the impact that education has suffered because of the Covid-19 pandemic, where the way of providing classes has taken a 360-degree turn; that is, a transition from the face-to-face format to the virtual one. The objective of this research was to update the theoretical and practical knowledge of teachers of basic education and high school on issues of digital educational innovation, to strengthen the evolution of coordinated teaching, to achieve results that directly affect the quality of education and life of a social group by providing easy-to-use tools and free access for both teachers and students for the realization of synchronous and asynchronous work. From this, efforts have been made to improve the effectiveness and efficiency within the classes given by the professors to their students and to establish a more spontaneous communication. In this planning, the technological tools that were necessary for its formation and future application were identified, this was carried out prior to a dialogue.El presente artículo se ha desarrollado con el fin de responder a la necesidad de implementar una mejora de procesos y procedimientos dentro de la enseñanza a 24 beneficiarios de la Unidad Educativa Réplica Eugenio Espejo debido al impacto que ha sufrido la educación por causa de la pandemia Covid-19, en donde la forma de brindar las clases ha dado un giro de 360 grados; es decir, una transición del formato presencial al virtual.

Grassroots Agency: Participation and Conflict in Buenos Aires Shantytowns seen through the Pilot Plan for Villa 7 (1971–1975)

open access articleIn 1971, after more than a decade of national and municipal policies aimed at the top-down removal of shantytowns, the Buenos Aires City Council approved the Plan Piloto para la Relocalización de Villa 7 (Pilot Plan for the Relocation of Shantytown 7; 1971–1975, referred to as the Pilot Plan hereinafter). This particular plan, which resulted in the construction of the housing complex, Barrio Justo Suárez, endures in the collective memory of Argentines as a landmark project regarding grassroots participation in state housing initiatives addressed at shantytowns. Emerging from a context of a housing shortage for the growing urban poor and intense popular mobilizations during the transition to democracy, the authors of the Pilot Plan sought to empower shantytown residents in novel ways by: 1) maintaining the shantytown’s location as opposed to eradication schemes that relocated the residents elsewhere, 2) formally employing some of the residents for the stage of construction, as opposed to “self-help” housing projects in which the residents contributed with unpaid labor, and 3) including them in the urban and architectural design of the of the new housing. This paper will examine the context in which the Pilot Plan was conceived of as a way of re-assessing the roles of the state, the user, and housing-related professionals, often seen as antagonistic. The paper argues that residents’ fair participation and state intervention in housing schemes are not necessarily incompatible, and can function in specific social and political contexts through multiactor proposals backed by a political will that prioritizes grassroots agency

RAGE and ICAM-1 differentially control leukocyte recruitment during acute inflammation in a stimulus-dependent manner

<p>Abstract</p> <p>Background</p> <p>The receptor for advanced glycation endproducts, RAGE, is involved in the pathogenesis of many inflammatory conditions, which is mostly related to its strong activation of NF-κB but also due to its function as ligand for the β₂-integrin Mac-1. To further dissect the stimulus-dependent role of RAGE on leukocyte recruitment during inflammation, we investigated β₂-integrin-dependent leukocyte adhesion in <it>RAGE^-/-</it>and <it>Icam1^-/-</it>mice in different cremaster muscle models of inflammation using intravital microscopy.</p> <p>Results</p> <p>We demonstrate that RAGE, but not ICAM-1 substantially contributes to N-formyl-methionyl-leucyl-phenylalanine (fMLP)-induced leukocyte adhesion in TNF-α-pretreated cremaster muscle venules in a Mac-1-dependent manner. In contrast, fMLP-stimulated leukocyte adhesion in unstimulated cremaster muscle venules is independent of RAGE, but dependent on ICAM-1 and its interaction with LFA-1. Furthermore, chemokine CXCL1-stimulated leukocyte adhesion in surgically prepared cremaster muscle venules was independent of RAGE but strongly dependent on ICAM-1 and LFA-1 suggesting a differential and stimulus-dependent regulation of leukocyte adhesion during inflammation in vivo.</p> <p>Conclusion</p> <p>Our results demonstrate that RAGE and ICAM-1 differentially regulate leukocyte adhesion in vivo in a stimulus-dependent manner.</p

Elevated circulating levels of succinate in human obesity are linked to specific gut microbiota

Gut microbiota-related metabolites are potential clinical biomarkers for cardiovascular disease (CVD). Circulating succinate, a metabolite produced by both microbiota and the host, is increased in hypertension, ischemic heart disease, and type 2 diabetes. We aimed to analyze systemic levels of succinate in obesity, a major risk factor for CVD, and its relationship with gut microbiome. We explored the association of circulating succinate with specific metagenomic signatures in cross-sectional and prospective cohorts of Caucasian Spanish subjects. Obesity was associated with elevated levels of circulating succinate concomitant with impaired glucose metabolism. This increase was associated with specific changes in gut microbiota related to succinate metabolism: a higher relative abundance of succinate-producing Prevotellaceae (P) and Veillonellaceae (V), and a lower relative abundance of succinate-consuming Odoribacteraceae (O) and Clostridaceae (C) in obese individuals, with the (P + V/O + C) ratio being a main determinant of plasma succinate. Weight loss intervention decreased (P + V/O + C) ratio coincident with the reduction in circulating succinate. In the spontaneous evolution after good dietary advice, alterations in circulating succinate levels were linked to specific metagenomic signatures associated with carbohydrate metabolism and energy production with independence of body weight change. Our data support the importance of microbe-microbe interactions for the metabolite signature of gut microbiome and uncover succinate as a potential microbiota-derived metabolite related to CVD risk

Network analysis of sea turtle movements and connectivity: A tool for conservation prioritization

Aim: Understanding the spatial ecology of animal movements is a critical element in conserving long-lived, highly mobile marine species. Analyzing networks developed from movements of six sea turtle species reveals marine connectivity and can help prioritize conservation efforts. Location: Global. Methods: We collated telemetry data from 1235 individuals and reviewed the literature to determine our dataset's representativeness. We used the telemetry data to develop spatial networks at different scales to examine areas, connections, and their geographic arrangement. We used graph theory metrics to compare networks across regions and species and to identify the role of important areas and connections. Results: Relevant literature and citations for data used in this study had very little overlap. Network analysis showed that sampling effort influenced network structure, and the arrangement of areas and connections for most networks was complex. However, important areas and connections identified by graph theory metrics can be different than areas of high data density. For the global network, marine regions in the Mediterranean had high closeness, while links with high betweenness among marine regions in the South Atlantic were critical for maintaining connectivity. Comparisons among species-specific networks showed that functional connectivity was related to movement ecology, resulting in networks composed of different areas and links. Main conclusions: Network analysis identified the structure and functional connectivity of the sea turtles in our sample at multiple scales. These network characteristics could help guide the coordination of management strategies for wide-ranging animals throughout their geographic extent. Most networks had complex structures that can contribute to greater robustness but may be more difficult to manage changes when compared to simpler forms. Area-based conservation measures would benefit sea turtle populations when directed toward areas with high closeness dominating network function. Promoting seascape connectivity of links with high betweenness would decrease network vulnerability.Fil: Kot, Connie Y.. University of Duke; Estados UnidosFil: Åkesson, Susanne.

Diseño estratégico de vanguardia

La integración del diseño con la vanguardia se observa natural, esto es, el diseño es una disciplina abductiva y la vanguardia persigue fines prospectivos, es decir, en ambos casos se trata de objetivos de posibilidad futura. De tal suerte, este libro, emanado de una parte de las ponencias rigurosamente arbitradas del Coloquio Internacional de Diseño 2016, está dividido en tres secciones o capítulos, a saber, el capítulo uno relacionado con la teoría y metodología para proyectos de diseño de vanguardia, el segundo sobre la tecnología, la innovación y la sostenibilidad de vanguardia de dichos proyectos, y finalmente el último capítulo, vinculado con la gestión estratégica de proyectos de vanguardia.La historia se forja de hechos e interpretaciones, de pasados construidos y de presentes en procesos constantes, estudiados en forma estricta por las ciencias. Por su parte, el futuro ostenta la posibilidad de ser indefinidamente planeado con base en las variopintas aproximaciones teóricas y empíricas que dan fundamento a este tipo de ciencia; éstas son denominadas prospectivas y sus bases vanguardias. Resulta importante señalar, que estas posibilidades sólo permiten tener una idea hipotética de lo que será la realidad y el mundo de vida de los seres vivos y su contexto, no obstante, se trata de la única manera racional que tiene el ser humano de prever ese futuro posible. Las distintas ciencias y disciplinas nos permiten construir históricamente estas posibilidades partiendo de datos, hechos, significados y un sinfín de informaciones que le dan cuerpo y sentido a tales posibilidades. En este sentido, la vanguardia, como base del conocimiento prospectivo, observa la necesidad de ser escrita, leída y discutida en los términos más estrictos con el fin de volver las predicciones más precisas. El diseño por su parte, es definido de manera sucinta como la disciplina proyectual estratégica y sistémica de la posibilidad, dirigida a procesos de significación utilitaria y simbólica para la comprensión –o interpretación– y modificación –o proyectación– de niveles de realidad (referentes y sujetos) desde diversos aparatos teóricos y empíricos –perspectivas disciplinarias–
