Espacios Saludables en Bogotá: el caso de Plaza España
59 p.El presente informe de investigación, consiste en la exploración de un entorno urbano como La Plaza España en Bogotá con el fin de identificar el potencial de esta como un espacio saludable dentro de la ciudad. Este proyecto tiene como sustentos teóricos una apuesta por comprender la ciudad desde la psicología social y su impacto en la salud. Es una investigación de tipo mixta, exploratoria donde se emplean diferentes herramientas para la recolección de la información como lo son: cartografía social, diarios de campo y encuestas dirigidas a la población relacionada con el uso y el consumo de este espacio público en Bogotá. Para analizar se empleó el modelo comunicativo cartografía (Lizmova,2007); el resultado de las cartografías se analiza en mesa de trabajo en la modalidad de discusión de grupo con el objetivo de diseñar y elaborar las encuestas y; la información de las encuestas y diarios de campo es posteriormente analizada a través de matrices compuestas por encuestas y diarios de campo realizados, dicho análisis permitió conocer algunas características significativas que pueden determinar este entorno como un posible espacio saludable en la ciudad. La investigación permitió identificar que la muestra de usuarios tiene percepción negativa frente a las categorías de seguridad y convivencia ciudadana, cultura y recreación, salud y bienestar, medio ambiente, nivel socioeconómico, espacio público, educación y participación ciudadana; por otra parte, se identifica percepción positiva frente a la movilidad y la oportunidad laboral en la Plaza España.PregradoPsicólog
Adoption of digital tools in the context of the COVID-19 pandemic in the Region of the Americas - the Go.Data experience
The COVID-19 pandemic has accelerated the growth of digital health tools. Although a number of different tools exist to support field data collection in the context of outbreak response, they have not been sufficient. This prompted the World Health Organization (WHO) to collaborate with the Global Outbreak Alert and Response Network (GOARN) and GOARN partners to develop a comprehensive system, Go.Data. Go.Data, a digital tool for outbreak response has simplified how countries operationalize and monitor case and contact data. Since the start of the pandemic, WHO and GOARN partners have provided support to Go.Data projects in 65 countries and territories, yet the demand by countries to have documented success cases of Go.Data implementations continues to grow. This viewpoint documents the successful Go.Data implementation frameworks in two countries, Argentina and Guatemala and an academic institution, the University of Texas at Austin
Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism
Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio
High prevalence and diversity of HIV-1 non-B genetic forms due to immigration in southern Spain: A phylogeographic approach
Phylogenetic studies are a valuable tool to understand viral transmission patterns and the role of immigration in HIV-1 spread. We analyzed the spatio-temporal relationship of different HIV-1 non-B subtype variants over time using phylogenetic analysis techniques. We collected 693 pol (PR+RT) sequences that were sampled from 2005 to 2012 from naïve patients in different hospitals in southern Spain. We used REGA v3.0 to classify them into subtypes and recombinant forms, which were confirmed by phylogenetic analysis through maximum likelihood (ML) using RAxML. For the main HIV-1 non-B variants, publicly available, genetically similar sequences were sought using HIV-BLAST. The presence of HIV-1 lineages circulating in our study population was established using ML and Bayesian inference (BEAST v1.7.5) and transmission networks were identified. We detected 165 (23.4%) patients infected with HIV-1 non-B variants: 104 (63%) with recombinant viruses in pol: CRF02_AG (71, 43%), CRF14_BG (8, 4.8%), CRF06_cpx (5, 3%) and nine other recombinant forms (11, 6.7%) and unique recombinants (9, 5.5%). The rest (61, 37%) were infected with non-recombinant subtypes: A1 (30, 18.2%), C (7, [4.2%]), D (3, [1.8%]), F1 (9, 5.5%) and G (12, 7.3%). Most patients infected with HIV-1 non-B variants were men (63%, p < 0.001) aged over 35 (73.5%, p < 0.001), heterosexuals (92.2%, p < 0.001), from Africa (59.5%, p < 0.001) and living in the El Ejido area (62.4%, p<0.001). We found lineages of epidemiological relevance (mainly within Subtype A1), imported primarily through female sex workers from East Europe. We detected 11 transmission clusters of HIV-1 non-B Subtypes, which included patients born in Spain in half of them. We present the phylogenetic profiles of the HIV-1 non-B variants detected in southern Spain, and explore their putative geographical origins. Our data reveals a high HIV-1 genetic diversity likely due to the import of viral lineages that circulate in other countries. The highly immigrated El Ejido area acts as a gateway through which different subtypes are introduced into other regions, hence the importance of setting up epidemiological control measures to prevent future outbreaks
Phylodynamic and Phylogeographic Profiles of Subtype B HIV-1 Epidemics in South Spain
Since 1982, HIV-1 epidemics have evolved to different scenarios in terms of transmission routes, subtype distribution and characteristics of transmission clusters. We investigated the evolutionary history of HIV-1 subtype B in south Spain.We studied all newly diagnosed HIV-1 subtype B patients in East Andalusia during the 2005-2012 period. For the analysis, we used the reverse transcriptase and protease sequences from baseline resistance, and the Trugene® HIV Genotyping kit (Siemens, Barcelona, Spain). Subtyping was done with REGA v3.0. The maximum likelihood trees constructed with RAxML were used to study HIV-1 clustering. Phylogeographic and phylodynamic profiles were studied by Bayesian inference methods with BEAST v1.7.5 and SPREAD v1.0.6.Of the 493 patients infected with HIV-1 subtype B, 234 grouped into 55 clusters, most of which were small (44 clusters ≤ 5 patients, 31 with 2 patients, 13 with 3). The rest (133/234) were grouped into 11 clusters with ≥ 5 patients, and most (82%, 109/133) were men who have sex with men (MSM) grouped into 8 clusters. The association with clusters was more frequent in Spanish (p = 0.02) men (p< 0.001), MSM (p<0.001) younger than 35 years (p = 0.001) and with a CD4+ T-cell count above 350 cells/ul (p<0.001). We estimated the date of HIV-1 subtype B regional epidemic diversification around 1970 (95% CI: 1965-1987), with an evolutionary rate of 2.4 (95%CI: 1.7-3.1) x 10-3 substitutions/site/year. Most clusters originated in the 1990s in MSMs. We observed exponential subtype B HIV-1 growth in 1980-1990 and 2005-2008. The most significant migration routes for subtype B went from inland cities to seaside locations.We provide the first data on the phylodynamic and phylogeographic profiles of HIV-1 subtype B in south Spain. Our findings of transmission clustering among MSMs should alert healthcare managers to enhance preventive measures in this risk group in order to prevent future outbreaks
Balance de 25 años de jurisprudencia de la Corte Constitucional
La Corte Constitucional de Colombia ha tenido un importante impacto en la vida social, cultural y política del país, a tal punto que, desde su creación, la jurisprudencia de este tribunal se ha convertido en un referente mundial acerca de las diversas materias sobre las que se ha pronunciado .
Este libro presenta un balance de la jurisprudencia que durante sus primeros veinticinco años la Corte ha expedido. Con este fin, el magistrado Luis Guillermo Guerrero Pérez y los magistrados auxiliares Miguel Polo Rosero y Claudia Escobar García recogen los trabajos de expertos nacionales e internacionales, funcionarios del Estado y Miembros de la sociedad civil que se presentaron en el XII Encuentro de la Jurisdicción Constitucional, realizado en la ciudad de San Juan de Pasto entre el 27 y el 30 de septiembre de 2017. En ese encuentro, se ratificó que la Corte Constitucional tiene la tarea de velar por la integridad de los compromisos de la Constitución.
Los capítulos que conforman este libro ofrecen una mirada multidisciplinaria sobre la eficacia y el impacto de las decisiones de la Corte, específicamente en lo que tiene que ver con la democracia y la participación, el sistema de salud, el sistema pensional, el medio ambiente y el fenómeno discriminatorio con la relación al género y a la condición de discapacidad en Colombia.Bogot
