Promoción de Salud y Prevención de Accidentes: Reflexiones Estudiantes Enfermería

La significancia de daños físicos, psicológicos, espirituales, sociales, económicos de accidentes exige reflexión. Promoción pretende empoderar a personas y comunidades sobre salud: no es “algo” a conservar, sino “algo” a desarrollar a partir de propios recursos, fortalezas, responsabilidades y gestión. Prevención pretende identificar Factores de Riesgo (1). Promoción y Prevención desde perspectiva psicoanalítica funda en conceptos: pulsión de vida, pulsión de muerte para comprender psiquismo y relación con la vida y “mal vivir”. El primero tendería al autocuidado, cuidado de otros y bienestar social; el segundo empuja al “mal vivir”.  ¿Por qué sujetos conociendo riesgos no realizan  acción preventiva? No existen factores subjetivos, sociales, culturales que  determinan; la información resulta escasa, ineficaz. Prevención debe contemplar “procesos preventivos” acción creativa transforma realidad promoviéndola en otros, elaborar factores, reflexionar, buscar significaciones que patologías sociales tienen para el sujeto(2). Información Per sé no genera comportamiento preventivo…imaginario social y asociación “accidente-muerte” genera mecanismo defensivo social de re-negación “a mí no me va a pasar”, adolescentes sostienen con mayor fuerza. Transgresor habla por sí, niega vínculo con otro. Buscar causas es responsabilidad. Población se “queja” del peligro; primer síntoma hacerlo propio, involucrarse, descubrirá  estructura de causas (3). Taller Extensión Universitaria para generar reflexión estudiantes enfermería sobre Promoción de Salud, Prevención Accidentes. Mayo 2012. Material y Método: Estudio cualitativo, transversal. Evaluación Inicial, cuestionario abierto (N:20) Resultados Opinan: “promoción es fomentar buenos hábitos físicos, psicológicos, evitar enfermedades”…para buen nivel de vida...” “..Deben trabajar prevención, equipo de salud, población en general”. “Información de medios masivos no suficiente, ni eficiente; no  tomada en cuenta”…”población actúa de la misma manera, debido a la falta de conciencia individual con  autoconvencimiento de  “a mi no me pasará”. Mayoría transgredió norma vial, no usó casco, cruzó calle sin respetar semáforo, distraído. “Conociendo riesgos población no realiza acción preventiva, no toman conciencia de protagonizar accidentes”. Factores de riesgo en hogar: cocina, electricidad. Vía pública: tránsito vehicular inadecuado, mal funcionamiento semáforos. Escuela: juegos bruscos, objetos cortopunzantes. Trabajo: indumentaria inadecuada, ausencia de normas de bioseguridad. Deportes: infraestructura inadecuada juegos bruscos. Grupos de  riesgo en hogar: niños, ancianos y de mayor incidencia, accidentes de tránsito en Orán: ADOLESCENTES. Estrategias: talleres, recursos audiovisuales, experiencias personales de accidentes; para adolescentes, familias; participación intersectorial de diferentes organismos, Medios Masivos de comunicación. Conclusión: Estudiantes conocen promoción, prevención e implicancias. Reflexionan sobre incidencia, accidentes de tránsito, identifican factores y grupos en riesgos. Importante responsabilizar a instituciones y sociedad, generar autocuidado, hábitos de vida saludable.  Proponen estrategias educativas.

Excitation of standing kink oscillations in coronal loops

In this work we review the efforts that have been done to study the excitation of the standing fast kink body mode in coronal loops. We mainly focus on the time-dependent problem, which is appropriate to describe flare or CME induced kink oscillations. The analytical and numerical studies in slab and cylindrical loop geometries are reviewed. We discuss the results from very simple one-dimensional models to more realistic (but still simple) loop configurations. We emphasise how the results of the initial value problem complement the eigenmode calculations. The possible damping mechanisms of the kink oscillations are also discussed

Total photoproduction cross-section at very high energy

In this paper we apply to photoproduction total cross-section a model we have proposed for purely hadronic processes and which is based on QCD mini-jets and soft gluon re-summation. We compare the predictions of our model with the HERA data as well as with other models. For cosmic rays, our model predicts substantially higher cross-sections at TeV energies than models based on factorization but lower than models based on mini-jets alone, without soft gluons. We discuss the origin of this difference.Comment: 13 pages, 9 figures. Accepted for publication in EPJC. Changes concern added references, clarifications of the Soft Gluon Resummation method used in the paper, and other changes requested by the Journal referee which do not change the results of the original versio

Microbial Translocation Is Associated with Extensive Immune Activation in Dengue Virus Infected Patients with Severe Disease

Background:Severe dengue virus (DENV) disease is associated with extensive immune activation, characterized by a cytokine storm. Previously, elevated lipopolysaccharide (LPS) levels in dengue were found to correlate with clinical disease severity. In the present cross-sectional study we identified markers of microbial translocation and immune activation, which are associated with severe manifestations of DENV infection.Methods:Serum samples from DENV-infected patients were collected during the outbreak in 2010 in the State of São Paulo, Brazil. Levels of LPS, lipopolysaccharide binding protein (LBP), soluble CD14 (sCD14) and IgM and IgG endotoxin core antibodies were determined by ELISA. Thirty cytokines were quantified using a multiplex luminex system. Patients were classified according to the 2009 WHO classification and the occurrence of plasma leakage/shock and hemorrhage. Moreover, a (non-supervised) cluster analysis based on the expression of the quantified cytokines was applied to identify groups of patients with similar cytokine profiles. Markers of microbial translocation were linked to groups with similar clinical disease severity and clusters with similar cytokine profiles.Results:Cluster analysis indicated that LPS levels were significantly increased in patients with a profound pro-inflammatory cytokine profile. LBP and sCD14 showed significantly increased levels in patients with severe disease in the clinical classification and in patients with severe inflammation in the cluster analysis. With both the clinical classification and the cluster analysis, levels of IL-6, IL-8, sIL-2R, MCP-1, RANTES, HGF, G-CSF and EGF were associated with severe disease.Conclusions:The present study provides evidence that both microbial translocation and extensive immune activation occur during severe DENV infection and may play an important role in the pathogenesis

Multiwavelength studies of MHD waves in the solar chromosphere: An overview of recent results

The chromosphere is a thin layer of the solar atmosphere that bridges the relatively cool photosphere and the intensely heated transition region and corona. Compressible and incompressible waves propagating through the chromosphere can supply significant amounts of energy to the interface region and corona. In recent years an abundance of high-resolution observations from state-of-the-art facilities have provided new and exciting ways of disentangling the characteristics of oscillatory phenomena propagating through the dynamic chromosphere. Coupled with rapid advancements in magnetohydrodynamic wave theory, we are now in an ideal position to thoroughly investigate the role waves play in supplying energy to sustain chromospheric and coronal heating. Here, we review the recent progress made in characterising, categorising and interpreting oscillations manifesting in the solar chromosphere, with an impetus placed on their intrinsic energetics.Comment: 48 pages, 25 figures, accepted into Space Science Review

An Integrated TCGA Pan-Cancer Clinical Data Resource to Drive High-Quality Survival Outcome Analytics

For a decade, The Cancer Genome Atlas (TCGA) program collected clinicopathologic annotation data along with multi-platform molecular profiles of more than 11,000 human tumors across 33 different cancer types. TCGA clinical data contain key features representing the democratized nature of the data collection process. To ensure proper use of this large clinical dataset associated with genomic features, we developed a standardized dataset named the TCGA Pan-Cancer Clinical Data Resource (TCGA-CDR), which includes four major clinical outcome endpoints. In addition to detailing major challenges and statistical limitations encountered during the effort of integrating the acquired clinical data, we present a summary that includes endpoint usage recommendations for each cancer type. These TCGA-CDR findings appear to be consistent with cancer genomics studies independent of the TCGA effort and provide opportunities for investigating cancer biology using clinical correlates at an unprecedented scale. Analysis of clinicopathologic annotations for over 11,000 cancer patients in the TCGA program leads to the generation of TCGA Clinical Data Resource, which provides recommendations of clinical outcome endpoint usage for 33 cancer types

Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory

Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the impact of atmospheric variations on extensive air showers by means of the surface detector of the Pierre Auger Observatory. The rate of events shows a ~10% seasonal modulation and ~2% diurnal one. We find that the observed behaviour is explained by a model including the effects associated with the variations of pressure and density. The former affects the longitudinal development of air showers while the latter influences the Moliere radius and hence the lateral distribution of the shower particles. The model is validated with full simulations of extensive air showers using atmospheric profiles measured at the site of the Pierre Auger Observatory.Comment: 24 pages, 9 figures, accepted for publication in Astroparticle Physic
