Translation and validation of the Spanish version of the Chronic Illness Anticipated Stigma Scale (CIASS) in Colombian patients diagnosed with chronic illnesses

Objective: Determine the psychometric properties of the CIASS scale for Colombian patients living with chronic diseases. Method: A Spanish version of the scale was distributed to a sample of 230 patients (33.2% male, aged 18–98 years) diagnosed with chronic diseases. A confirmatory factor analysis was performed using unweighted least squares to determine the scale’s structural validity, Cronbach’s alpha was calculated to determine the scale’s reliability, and correlations with related constructs were calculated to determine the scale’s convergent validity. Results: Confirmatory factor analysis suggested that the factor structure of the scale was a satisfactory fit to the proposed theoretical model (χ2 = 3133.26, df = 526, root mean square error of approximation [RMSEA] = 0.082, P-Value = 0.00, CFI = 1.00, root mean square residual [RMR] = 0.11). The internal consistency of the scale was strong (Cronbach’s α = .815), indicating that the scale was reliable. We found that the discrimination index of CIASS scale items were high (r =  .647–.870). Convergent validity was also supported, associations observed with lower coping and greater negative emotion scores. Conclusion: The CIASS scale is a valid and reliable instrument for the assessment of anticipated stigma in Colombian patients with chronic illnesses

Toward an integrative understanding of social behavior: new models and new opportunities.

Social interactions among conspecifics are a fundamental and adaptively significant component of the biology of numerous species. Such interactions give rise to group living as well as many of the complex forms of cooperation and conflict that occur within animal groups. Although previous conceptual models have focused on the ecological causes and fitness consequences of variation in social interactions, recent developments in endocrinology, neuroscience, and molecular genetics offer exciting opportunities to develop more integrated research programs that will facilitate new insights into the physiological causes and consequences of social variation. Here, we propose an integrative framework of social behavior that emphasizes relationships between ultimate-level function and proximate-level mechanism, thereby providing a foundation for exploring the full diversity of factors that underlie variation in social interactions, and ultimately sociality. In addition to identifying new model systems for the study of human psychopathologies, this framework provides a mechanistic basis for predicting how social behavior will change in response to environmental variation. We argue that the study of non-model organisms is essential for implementing this integrative model of social behavior because such species can be studied simultaneously in the lab and field, thereby allowing integration of rigorously controlled experimental manipulations with detailed observations of the ecological contexts in which interactions among conspecifics occur

Labor Law in Colombia: Emergence of a Local Socialist Perspective (1930-1945)

Este artículo controvierte la tesis generalizada sobre el origen del derecho laboral en Colombia, que lo explica como una concesión del presidente Alfonso López al movimiento obrero por su apoyo durante el intento de golpe de 1944. Mediante un análisis histórico basado en la revisión de fuentes primarias, se argumenta que desde comienzos de la década de 1930 existieron diversas corrientes académicas y políticas que proponían desarrollar esta rama del derecho. Se profundiza en la apropiación crítica de teorías jurídicas transnacionales por los socialistas locales para poner en cuestión la supuesta insularidad y aislamiento intelectuales de la academia en Colombia y de este grupo en particular. Se concluye que el derecho laboral, entendido como derecho social por los socialistas, se nutrió de, al menos, cuatro fuentes: las corrientes antiformalistas, el materialismo dialectico y su expresión en el derecho soviético, el constitucionalismo social francés y el laboralismo inglés.This article challenges the general thesis on the origin of labor law in Colombia, explaining it as a concession given by president AlfonsoLópez to the workers movement for its support during the coup d’état attempt in 1944. Through a historical analysis based on the revision of primary sources, the article states that there were several academic and political currents early in the 1930’s that proposed the development of this branch of law. The article goes deeper in the critical appropriation of translational legal theories by local socialists intended to question the presumable intellectual isolation of the Colombian academicians and particularly this group. The article concludes that the labor law, understood as social right by socialists, was based at least on four sources: antiformalist currents; dialectic materialism and its expression in the Soviet law; the French social constitutionalism; and the English labor movement

Deleción terminal del brazo largo del cromosoma 9 en leucemia promielocítica aguda

La Leucemia Promielocítica Aguda (LPA), definida como M3 en la clasificación francesa-americana- británica (FAB)(1), se caracteriza por presentar una translocación cromosómica al azar t(15;17)(q22;q21). En esta translocación se fusionan los receptores del ácido retinoíco ?(? RAR) gen localizado en el cromosoma 17 y el gen PML sobre el cromosoma 15(2). Por otra lado, la deleción del brazo largo del cromosoma 9(9q-) es una alteración rara específica encontrada en (LMA) como una anormalidad única del cariotipo o como un cambio secundario, particularmente junto con t(8;21)(q22;q22)(3,4). La mayoría de ellas son deleciones intersticiales, 9q12 y 9q22; constituyen el sitio más común de ruptura proximal y distal (5)

Occurrence and distribution of Bemisia tabaci and Trialeurodes vaporariorum (Hemiptera: Aleyrodidae) on tomato crops in Panama

The main open-field and greenhouse producer regions of tomato in Panama (Los Santos, Herrera, Veraguas and Chiriquí provinces) were surveyed to determine the occurrence and distribution of Bemisia tabaci and Trialeurodes vaporariorum during the growing seasons of 2017 and 2018. Twenty-two plots were surveyed, and DNA extracts of 112 adult whiteflies were analyzed by multiplex PCR, using a set of specific primers of B. tabaci MEAM1, B. tabaci NW, and T. vaporariorum. DNA extracts corresponding to 57 individual whiteflies (50.9 %) rendered PCR products of expected size with B. tabaci-specific primers (37 belonged to B. tabaci MEAM1 and 20 to B. tabaci NW), whereas the remaining DNA extracts corresponding to 55 individual whiteflies (49.1 %) rendered the product of the expected size with T. vaporariorumspecific primers. The sequencing of those PCR products and BLAST analysis allowed for the identification of B. tabaci MEAM1, B. tabaci NW, and T. vaporariorum. Bemisia tabaci NW was detected in all four provinces, while B. tabaci MEAM1 was detected in the provinces of Los Santos, Herrera and Chiriquí, and T. vaporariorum was detected only in the province of Chiriquí. Bemisia tabaci MEAM1, B. tabaci NW and T. vaporariorum were detected in both production systems (open fields and greenhouse). Bemisia tabaci MEAM1 and B. tabaci NW were detected in the tropical rainforest (Af) and tropical savanna (Aw) climates, at an altitudinal range of 19–1543 meters above sea level (MASL), while Trialeurodes vaporariorum was found only in the Af climate, at an altitudinal range of 818–1661 MASL. To our knowledge, this is not only the first report of B. tabaci MEAM1 and B. tabaci NW at an altitude above 1000 MASL in Panama, but it is also the first report of T. vaporariorum at an altitude under 1000 MASL in this country. Information about the identification and geographic distribution of whiteflies in Panama will help to design effective strategies for pest management

Ongoing diversification of the global fish pathogen Piscirickettsia salmonis through genetic isolation and transposition bursts

The management of bacterial pathogens remains a key challenge of aquaculture. The marine gammaproteobacterium Piscirickettsia salmonis is the etiological agent of piscirickettsiosis and causes multi-systemic infections in different salmon species, resulting in considerable mortality and substantial commercial losses. Here, we elucidate its global diversity, evolution, and selection during human interventions. Our comprehensive analysis of 73 closed, high quality genome sequences covered strains from major outbreaks and was supplemented by an analysis of all P. salmonis 16S rRNA gene sequences and metagenomic reads available in public databases. Genome comparison showed that Piscirickettsia comprises at least three distinct, genetically isolated species of which two showed evidence for continuing speciation. However, at least twice the number of species exist in marine fish or seawater. A hallmark of Piscirickettsia diversification is the unprecedented amount and diversity of transposases which are particularly active in subgroups undergoing rapid speciation and are key to the acquisition of novel genes and to pseudogenization. Several group-specific genes are involved in surface antigen synthesis and may explain the differences in virulence between strains. However, the frequent failure of antibiotic treatment of piscirickettsiosis outbreaks cannot be explained by horizontal acquisition of resistance genes which so far occurred only very rarely. Besides revealing a dynamic diversification of an important pathogen, our study also provides the data for improving its surveillance, predicting the emergence of novel lineages, and adapting aquaculture management, and thereby contributes towards the sustainability of salmon farming

Charge separation relative to the reaction plane in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}}= 2.76 TeV

Measurements of charge dependent azimuthal correlations with the ALICE detector at the LHC are reported for Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV. Two- and three-particle charge-dependent azimuthal correlations in the pseudo-rapidity range $|\eta| < 0.8$ are presented as a function of the collision centrality, particle separation in pseudo-rapidity, and transverse momentum. A clear signal compatible with a charge-dependent separation relative to the reaction plane is observed, which shows little or no collision energy dependence when compared to measurements at RHIC energies. This provides a new insight for understanding the nature of the charge dependent azimuthal correlations observed at RHIC and LHC energies.Comment: 12 pages, 3 captioned figures, authors from page 2 to 6, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/286
