Innovar , 2005,
Abstract: the present article approaches ? disability and work ? in spain as a social problem in construction, the slow social visibility of the group of disabled people, the evolution of the public policy of employment - passive and active - directed to this group, as well as the difficulties for a real social and labor integration of the disabled persons.
Desarrollo de una organización sistémica en la banca colombiana, 1990-2009
Carmen Marina López Pino,Enrique Seco Martín
Revista Venezolana de Gerencia , 2012,
Abstract: La organización sistémica es una configuración socio-técnica desarrollada por la banca a nivel global durante las últimas décadas, cuyos componentes fundamentales son: por un lado, la organización en red lo que implica procesos de informatización, sistematización interna y entrelazamiento permanente entre redes de proveedores y clientes, con diversos grados de interconexión, en ambientes sumamente competitivos; y, por otro lado, la flexibilidad organizativa tanto interna como externa (Ibarra, 2003; Nohria y Eccles, 1992; Weiss, 2008, Weiss et al., 2010). El objetivo de la investigación fue indagar en qué medida la banca colombiana se configura como una organización sistémica. Se concluye que a pesar de la heterogeneidad en el uso de tecnologías de información y comunicación (TIC′s), la banca tiende a consolidarse como un tipo de organización sistémica, transformando de manera significativa la relación con los clientes, los proveedores, la organización del trabajo, los perfiles de los trabajadores y las relaciones laborales. Desde la perspectiva metodológica de la triangulación, se integran técnicas cualitativas (entrevistas y grupos de discusión) y cuantitativas (encuesta), en un sentido de complementariedad de los dos métodos.

López Pino,Carmen Marina; Seco Martín,Enrique; Ramírez Camacho,Diana;
Cuadernos de Administración , 2011,
Abstract: the article uses a structural and inter-subjective approach to ask what structural and organizational factors favour practices of harassment at work in colombia. the initial hypothesis of the study is that there are structural conditions (economic crisis, business reconstruction, flexibility in the labour market etc.) and organizational structures in business which encourage practices of harassment at work or which do not favour its control. supported by the theory of bourdieu, the authors question the concept of harassment at work container in law 1010/2006 and draw up three types of harassment at work which illustrate different dimensions of the problem. they used qualitative techniques such as interviews and discussion groups, and analyzed court decisions and complaints of harassment at work received by the labour courts and the ministry of social protection.

Abstract: Desde una perspectiva estructural e intersubjetiva el artículo se pregunta qué factores estructurales y organizacionales favorecen las prácticas de acoso laboral en Colombia? La hipótesis inicial del estudio es que existen condiciones estructurales (crisis económicas, reestructuración empresarial, flexibilidad del mercado laboral, entre otras) y estructuras organizativas empresariales que propician la práctica del acoso laboral o que no favorecen el control de la misma. Apoyados en la teoría de Bourdieu, los autores cuestionan la conceptualización del acoso laboral contenida en la Ley 1010/2006 y elaboran tres tipologías del acoso laboral, que permiten vislumbrar dimensiones diferentes del problema. Emplearon técnicas cualitativas como las entrevistas y grupos de discusión, y analizaron sentencias y querellas de acoso laboral recabadas en juzgados laborales y en el Ministerio de la Protección Social.

Abstract: La bacteriemia relacionada con el catéter es una de las principales complicaciones aumentando el riesgo de pérdida del catéter o incluso la muerte del paciente. La utilización de sellado de las luces del catéter con antibióticos o el empleo de mupirocina tópica en el orificio de salida del catéter ha demostrado disminuir la incidencia de bacteriemia; sin embargo, un manejo lo más aséptico posible del catéter es la principal herramienta para disminuir esta incidencia. Objetivo: evaluar la tasa de incidencia de bacteriemias en pacientes portadores de catéter tunelizado sin la utilización de sellado con antibióticos ni la utilización de mupirocina haciendo especial hincapié en la asepsia durante la manipulación. Se incluyeron todos los pacientes portadores de catéter tunelizado desde el 1 de enero al 31 de diciembre de 2007. En total fueron 17 pacientes, 4 hombres y 13 mujeres con una edad media de 71,3 (11,3) a os. El protocolo consistía en la utilización de un campo los más aséptico posible, el uso de guantes cada vez que se manipulara el catéter, uso de mascarillas tanto por el manipulador como por el paciente y la desinfección del orificio de salida del túnel con clorhexidina, así como de ambas conexiones del catéter al comenzar y al finalizar la sesión. A fecha 31 de diciembre la prevalencia de pacientes con catéter tunelizado era del 38,5%. Durante el periodo de estudio se produjeron un total de 8 bacteriemias en un total de 4462 días de seguimiento (tasa de incidencia de 1,8 bacteriemias/1000 catéter-día). Cuatro hemocultivos fueron positivo a Staphylococcus epidermidis, 1 a Corynebacterium, 1 a Staphylococcus auricularis y 2 fueron negativos. No se produjo ninguna bacteriemia por Staphylococcus aureus ni tampoco algún signo de infección del orificio de salida. Conclusión: un manejo lo más aséptico posible del catéter disminuye el riesgo de bacteriemia relacionada con el catéter sin necesidad del empleo de sellado con antibióticos ni de mupirocina tópica. Catheter-related bacteriaemia is one of the main complications increasing the risk of loss of the catheter or even death of the patient. The use of sealing of the catheter lumen with antibiotics or the use of topical mupirocin on the exit orifice of the catheter have been proven to reduce the incident of bacteriaemia; however, the most aseptic possible handling of the catheter is the main tool for reducing this incidence. Goal: to assess the rate of incident of bacteriaeima in patients with permanent tunnelled haemodialysis catheters without the use of sealing with antibiotics or the use of mupiroci

Abstract: Translation/re-translation of the English versions of the NDI and the COM was done blindly and independently by a multidisciplinary team. The study was done in 9 primary care Centers and 12 specialty services from 9 regions in Spain, with 221 acute, subacute and chronic patients who visited their physician for NP: 54 in the pilot phase and 167 in the validation phase. Neck pain (VAS), referred pain (VAS), disability (NDI, COM and NPQ), catastrophizing (CSQ) and quality of life (SF-12) were measured on their first visit and 14 days later. Patients' self-assessment was used as the external criterion for pain and disability. In the pilot phase, patients' understanding of each item in the NDI and COM was assessed, and on day 1 test-retest reliability was estimated by giving a second NDI and COM in which the name of the questionnaires and the order of the items had been changed.Comprehensibility of NDI and COM were good. Minutes needed to fill out the questionnaires [median, (P25, P75)]: NDI. 4 (2.2, 10.0), COM: 2.1 (1.0, 4.9). Reliability: [ICC, (95%CI)]: NDI: 0.88 (0.80, 0.93). COM: 0.85 (0.75,0.91). Sensitivity to change: Effect size for patients having worsened, not changed and improved between days 1 and 15, according to the external criterion for disability: NDI: -0.24, 0.15, 0.66; NPQ: -0.14, 0.06, 0.67; COM: 0.05, 0.19, 0.92. Validity: Results of NDI, NPQ and COM were consistent with the external criterion for disability, whereas only those from NDI were consistent with the one for pain. Correlations with VAS, CSQ and SF-12 were similar for NDI and NPQ (absolute values between 0.36 and 0.50 on day 1, between 0.38 and 0.70 on day 15), and slightly lower for COM (between 0.36 and 0.48 on day 1, and between 0.33 and 0.61 on day 15). Correlation between NDI and NPQ: r = 0.84 on day 1, r = 0.91 on day 15. Correlation between COM and NPQ: r = 0.63 on day 1, r = 0.71 on day 15.Although most psychometric characteristics of NDI, NPQ and COM are similar, those from the lat

Abstract: Shiga toxin (Stx)-producing Escherichia coli (STEC) infection is associated with a broad spectrum of clinical manifestations that include diarrhea, hemorrhagic colitis, and hemolytic uremic syndrome (HUS). Systemic Stx toxemia is considered to be central to the genesis of HUS. Distinct methods have been used to evaluate anti-Stx response for immunodiagnostic or epidemiological analysis of HUS cases. The development of enzyme-linked immunosorbent assay (ELISA) and western blot (WB) assay to detect the presence of specific antibodies to Stx has introduced important advantages for serodiagnosis of HUS. However, application of these methods for seroepidemiological studies in Argentina has been limited. The aim of this work was to develop an ELISA to detect antibodies against the B subunit of Stx2, and a WB to evaluate antibodies against both subunits of Stx2 and Stx1, in order to analyze the pertinence and effectiveness of these techniques in the Argentinean population. We studied 72 normal healthy children (NHC) and 105 HUS patients of the urban pediatric population from the surrounding area of Buenos Aires city. Using the WB method we detected 67% of plasma from NHC reactive for Stx2, but only 8% for Stx1. These results are in agreement with the broad circulation of Stx2-expressing STEC in Argentina and the endemic behavior of HUS in this country. Moreover, the simultaneous evaluation by the two methods allowed us to differentiate acute HUS patients from NHC with a great specificity and accuracy, in order to confirm the HUS etiology when pathogenic bacteria were not isolated from stools.
Latest Insights on Adenovirus Structure and Assembly

Viruses , 2012, DOI: 10.3390/v4050847
Abstract: Adenovirus (AdV) capsid organization is considerably complex, not only because of its large size (~950 ?) and triangulation number (pseudo T = 25), but also because it contains four types of minor proteins in specialized locations modulating the quasi-equivalent icosahedral interactions. Up until 2009, only its major components (hexon, penton, and fiber) had separately been described in atomic detail. Their relationships within the virion, and the location of minor coat proteins, were inferred from combining the known crystal structures with increasingly more detailed cryo-electron microscopy (cryoEM) maps. There was no structural information on assembly intermediates. Later on that year, two reports described the structural differences between the mature and immature adenoviral particle, starting to shed light on the different stages of viral assembly, and giving further insights into the roles of core and minor coat proteins during morphogenesis?[1,2]. Finally, in 2010, two papers describing the atomic resolution structure of the complete virion appeared?[3,4]. These reports represent a veritable tour de force for two structural biology techniques: X-ray crystallography and cryoEM, as this is the largest macromolecular complex solved at high resolution by either of them. In particular, the cryoEM analysis provided an unprecedented clear picture of the complex protein networks shaping the icosahedral shell. Here I review these latest developments in the field of AdV structural studies.
