Participación de los adultos mayores del municipio de Cachipay – Cundinamarca en la construcción de una política pública que responda al fenómeno del envejecimiento

El interés de esta Investigación Diagnóstica es mostrar la importancia de la participación social de los adultos mayores en el proceso de diseño de políticas públicas en el Municipio de Cachipay. Se demuestra que las necesidades sentidas y las expectativas de atención integral identificadas desde los adultos mayores, aportan información fundamental y complementaria a los diagnósticos elaborados con base únicamente en fuentes institucionales. Tomando conceptos de vulnerabilidad, exclusión social, el principio de respeto a los derechos humanos y siguiendo la norma nacional contenida en la Ley 1251 de 2008 de envejecimiento y vejez, la investigación avanza en la identificación de conceptos, instrumentos y dinámicas de participación social, para que el gobierno local diseñe políticas públicas concertadas que garanticen una vida digna a la población de la tercera edad.

Efectos y reacciones al fallo de la Corte Internacional de Justicia - CIJ en el diferendo de Nicaragua c. Colombia

El fallo de la CIJ respecto del diferendo de Nicaragua contra Colombia reconfiguró las fronteras en el Caribe colombiano y el mapa de la nación. La mala socialización del fallo a nivel nacional y departamental, genera un ambiente de negativismo sobre el panorama actual y a mediano y largo plazo. Este ambiente da paso a una serie de reacciones que influyen en el debate nacional con respecto a los efectos del fallo, dejando de lado elementos de fondo pertinentes para su mejor comprensión, asimilación y debate. El Estudio de Caso que se desarrolla a continuación pretende, en primer lugar, contextualizar el proceso histórico y jurídico que dan paso a la sentencia de la CIJ. En segundo lugar, hacer un examen riguroso de los efectos generados en Colombia. Finalmente, en tercer lugar, se desea aportar elementos de análisis que se centren en los efectos reales para Colombia y el archipiélago.

Estrategia de difusión de la normatividad vigente de derechos de autor en cinco (5) escuelas de formación musical de Bogotá, dirigida a profesores y estudiantes de música

En la ciudad de Bogotá se han ido creando escuelas de formación musical que se fortalecen con el tiempo en razón a diversos factores tales como el interés de la población juvenil, la formación de docentes en música, el auge comercial de músicos colombianos de impacto internacional, entre otros.1 Sin embargo, una falencia que he identificado en mi condición de abogado y de músico aficionado ha sido la falta de formación de estos centros de enseñanza en el tema de Derechos de Autor y la apatía evidente en los alumnos para abordar el tema.

Las directrices establecidas por Brasil para la producción de biocombustibles a partir de productos agrícolas y su aplicabilidad para Colombia

Esta monografía pretende realizar un análisis desde la experiencia de Brasil de los elementos que debe contener el diseño de las directrices para la producción de biocombustibles en Colombia, centrados en la importancia de estructurar un modelo sostenible que le permita a Colombia consolidarse como productor eficiente a nivel mundial en la materia. La hipótesis que se prueba a lo largo de la monografía plantea que para entender qué elementos intervienen en el diseño de las directrices (entendidas como el conjunto de normas o instrucciones que determinan las condiciones de generación de biocombustibles, en este caso un marco legal que incentive y establezca reglas claras en la materia, innovación, capacidad de expansión, infraestructura y construcción de mercados) para la producción de biocombustibles en Brasil, es necesario realizar un análisis que involucre elementos agrícolas como el desarrollo rural, aspectos energéticos, entre los que se encuentran la seguridad energética, la dependencia frente a la volatilidad de los precios del petróleo y la disminución de los costos de los combustibles, y medio ambientales como la reducción de la emisión de gases invernadero, los daños derivados de la producción de petróleo y la protección de zonas forestales. Sin dejar de lado los tres momentos de la producción de biocombustibles: la siembra, producción y uso.

Systemic Lupus Erythematosus 2014

Systemic lupus erythematosus (SLE, lupus) is the prototype of systemic autoimmune disease (AD). Immune system activation in SLE is characterized by exaggerated B-cell and T-cell responses and loss of immune tolerance against selfantigens. Production and defective elimination of antibodies, circulation and tissue deposition of immune complexes, and complement and cytokine activation contribute to clinical manifestations that range from fatigue and joint pain to severe, life-threatening organ damage

The Autoimmune Tautology: From Polyautoimmunity and Familial Autoimmunity to the Autoimmune Genes

Autoimmune diseases (ADs) are chronic conditions initiated by the loss of immunological tolerance to self-antigens and represent a heterogeneous group of disorders that afflict specific target organs ormultiple organ systems [1]. The chronic nature of these diseases places a significant burden on the utilization of medical care, direct and indirect economic costs, and quality of life. The fact that ADs share several clinical signs and symptoms (i.e., subphenotypes), physiopathological mechanisms, and genetic factors has been called autoimmune tautology and indicates that they have common mechanisms

The Autoimmune Tautology: An In Silico Approach

There is genetic evidence of similarities and differences among autoimmune diseases (AIDs) that warrants looking at a general panorama of what has been published. Thus, our aim was to determine the main shared genes and to what extent they contribute to building clusters of AIDs. We combined a text-mining approach to build clusters of genetic concept profiles (GCPs) from the literature in MedLine with knowledge of protein-protein interactions to confirm if genes in GCP encode proteins that truly interact. We found three clusters in which the genes with the highest contribution encoded proteins that showed strong and specific interactions. After projecting the AIDs on a plane, two clusters could be discerned: Sjögren’s syndrome—systemic lupus erythematosus, and autoimmune thyroid disease—type1 diabetes—rheumatoid arthritis. Our results support the common origin of AIDs and the role of genes involved in apoptosis such as CTLA4, FASLG, and IL10.

Is there a common genetic basis for autoimmune diseases?

Autoimmune diseases (ADs) represent a diverse collection of diseases in terms of their demographic profile and primary clinical manifestations. The commonality between them however, is the damage to tissues and organs that arises from the response to self-antigens. The presence of shared pathophysiological mechanisms within ADs has stimulated searches for common genetic roots to these diseases. Two approaches have been undertaken to sustain the “common genetic origin” theory of ADs. Firstly, a clinical genetic analysis showed that autoimmunity aggregates within families of probands diagnosed with primary Sjögren's (pSS) syndrome or type 1 diabetes mellitus (T1D). A literature review supported the establishment of a familiar cluster of ADs depending upon the proband's disease phenotype. Secondly, in a same and well-defined population, a large genetic association study indicated that a number of polymorphic genes (i.e. HLA-DRB1, TNF and PTPN22) influence the susceptibility for acquiring different ADs. Likewise, association and linkage studies in different populations have revealed that several susceptibility loci overlap in ADs, and clinical studies have shown that frequent clustering of several ADs occurs. Thus, the genetic factors for ADs consist of two types: those which are common to many ADs (acting in epistatic pleitropy) and those that are specific to a given disorder. Their identification and functional characterization will allow us to predict their effect as well as to indicate potential new therapeutic interventions. Both autoimmunity family history and the co-occurrence of ADs in affected probands should be considered when performing genetic association and linkage studies.

Genetic basis of Sjögren's syndrome. How strong is the evidence?

Sjögren's syndrome (SS) is a late-onset chronic autoimmune disease (AID) affecting the exocrine glands, mainly the salivary and lachrymal. Genetic studies on twins with primary SS have not been performed, and only a few case reports describing twins have been published. The prevalence of primary SS in siblings has been estimated to be 0.09% while the reported general prevalence of the disease is approximately 0.1%. The observed aggregation of AIDs in families of patients with primary SS is nevertheless supportive for a genetic component in its etiology. In the absence of chromosomal regions identified by linkage studies, research has focused on candidate gene approaches (by biological plausibility) rather than on positional approaches. Ancestral haplotype 8.1 as well as TNF, IL10 and SSA1 loci have been consistently associated with the disease although they are not specific for SS. In this review, the genetic component of SS is discussed on the basis of three known observations: (a) age at onset and sex-dependent presentation, (b) familial clustering of the disease, and (c) dissection of the genetic component. Since there is no strong evidence for a specific genetic component in SS, a large international and collaborative study would be suitable to assess the genetics of this disorder.

What is next after the genes for autoimmunity?

Clinical pathologies draw us to envisage disease as either an independent entity or a diverse set of traits governed by common physiopathological mechanisms, prompted by environmental assaults throughout life. Autoimmune diseases are not an exception, given they represent a diverse collection of diseases in terms of their demographic profile and primary clinical manifestations. Although they are pleiotropic outcomes of non-specific disease genes underlying similar immunogenetic mechanisms, research generally focuses on a single disease. Drastic technologic advances are leading research to organize clinical genomic multidisciplinary approaches to decipher the nature of human biological systems. Once the currently costly omic-based technologies become universally accessible, the way will be paved for a cleaner picture to risk quantification, prevention, prognosis and diagnosis, allowing us to clearly define better phenotypes always ensuring the integrity of the individuals studied. However, making accurate predictions for most autoimmune diseases is an ambitious challenge, since the understanding of these pathologies is far from complete. Herein, some pitfalls and challenges of the genetics of autoimmune diseases are reviewed, and an approximation to the future of research in this field is presented.

The multiple autoimmune syndromes. A clue for the autoimmune tautology

The multiple autoimmune syndromes (MAS) consist on the presence of three or more well-defined autoimmune diseases (ADs) in a single patient. The aim of this study was to analyze the clinical and genetic characteristics of a large series of patients with MAS. A cluster analysis and familial aggregation analysis of ADs was performed in 84 patients. A genome-wide microsatellite screen was performed in MAS families, and associated loci were investigated through the pedigree disequilibrium test. Systemic lupus erythematosus (SLE), autoimmune thyroid disease (AITD), and Sjögren's syndrome together were the most frequent ADs encountered. Three main clusters were established. Aggregation for type 1 diabetes, AITD, SLE, and all ADs as a trait was found. Eight loci associated with MAS were observed harboring autoimmunity genes. The MAS represent the best example of polyautoimmunity as well as the effect of a single genotype on diverse phenotypes. Its study provides important clues to elucidate the common mechanisms of ADs (i.e., autoimmune tautology). © Springer Science+Business Media, LLC 2012.

Lupus nephritis in colombians: Contrasts and comparisons with other populations

Lupus nephritis (LN) is one of the most serious complications of systemic lupus erythematosus (SLE) since it is the major predictor of poor prognosis. The purpose of this study was to examine the clinical and immunological characteristics associated with LN development during the course of SLE in Colombians. Therefore, patients with SLE followed at five different referral centers in Medellin, Bogota, and Cali were included in this cross-sectional and multicenter study. Factors influencing LN were assessed by conditional logistic regression analysis, adjusting by gender, age at onset, duration of disease, and city of origin. The entire sample population included 467 patients, of whom 51% presented with LN. The presence of anti-dsDNA antibodies (adjusted odds ratio (AOR), 2.06; 95% confidence interval (CI), 1.16–3.65), pleuritis (AOR, 3.82; 95% CI, 1.38–10.54), and hypertension (AOR, 2.63; 95% CI, 1.23–5.62) were positively associated with LN, whereas the presence of anti-La antibodies was a protective factor against LN development (AOR, 0.4; 95% CI, 0.19–0.85). A review of literature on LN in different populations is made. The identified clinical- and laboratory-associated factors would assist earlier diagnosis and guide decisions on therapeutic interventions on this critical and frequent complication of SLE.

How do autoimmune diseases cluster in families? A systematic review and meta-analysis

Background: A primary characteristic of complex genetic diseases is that affected individuals tend to cluster in families (that is, familial aggregation). Aggregation of the same autoimmune condition, also referred to as familial autoimmune disease, has been extensively evaluated. However, aggregation of diverse autoimmune diseases, also known as familial autoimmunity, has been overlooked. Therefore, a systematic review and meta-analysis were performed aimed at gathering evidence about this topic. Methods: Familial autoimmunity was investigated in five major autoimmune diseases, namely, rheumatoid arthritis, systemic lupus erythematosus, autoimmune thyroid disease, multiple sclerosis and type 1 diabetes mellitus. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. Articles were searched in Pubmed and Embase databases. Results: Out of a total of 61 articles, 44 were selected for final analysis. Familial autoimmunity was found in all the autoimmune diseases investigated. Aggregation of autoimmune thyroid disease, followed by systemic lupus erythematosus and rheumatoid arthritis, was the most encountered. Conclusions: Familial autoimmunity is a frequently seen condition. Further study of familial autoimmunity will help to decipher the common mechanisms of autoimmunity.
