    El maltrato a las personas mayores es un tema de interés creciente, tanto así que se considera un problema de salud pública. Hay particularidades que hacen del entorno colombiano un ambiente propicio para generar situaciones de maltrato: la exposición a la “violencia a gran escala”, la diferencia de género y el cambio de la pirámide poblacional. Según el estudio SABE Colombia, el 12,9% de las personas mayores informó haber sufrido maltrato, del cual el más común es el psicológico, seguido por el físico, el financiero y el sexual. A pesar de que el Estado reconoce al adulto mayor como “sujeto de especial protección”, aún hay desconocimiento por parte de los profesionales de la salud a la hora de enfrentar estos casos. Este debería ser un tema de obligatoriedad moral, por lo que se debe abordar a profundidad para así identificarlo oportunamente y proponer estrategias de prevención de una manera contextualizada. Esta revisión de la literatura tiene por objetivos sintetizar la información epidemiológica disponible, los factores de riesgo y las estrategias de evaluación y plantear las rutas de atención idóneas asentadas en los aspectos legales alrededor del maltrato hacia los ancianos en Colombia.Artículo de revisión1-16Elder abuse is a topic of growing interest and it is considered as a public health problem. The Colombian context has built an ideal climate generating situations of abuse: the exposure to “violence on a large scale”, the gender gap and the change of the population pyramid. According to the SABE Colombia, 12.9% of the elderly reported having suffered abuse, the most common is psychological abuse, followed by the physical, financial and sexual. Although the Colombian State recognizes the elderly as a special subject of protection, perhaps there is still ignorance of the health professionals. This should be a moral obligation for the medical community, so it must be addressed in depth in order to identify cases in time and propose prevention. This review of the literature aims to synthesize the available epidemiological information, clinical evidence and legal aspects of elder abuse in the Colombian context and finally propose routes of attention with the legal aspects surrounding the abuse

    El promedio de edad de los pacientes que requieren hospitalización y manejo en la unidad de cuidados intensivos está aumentando, correspondiente a una mejor expectativa de vida y mejores herramientas clínicas, tecnológicas y farmacológicas para estas condiciones. Por lo tanto, más y más casos son observados en la unidad de cuidados intensivos de pacientes ancianos con compromiso renal severo. Esta situación justifica un conocimiento más profundo de la lesión renal aguda y el soporte renal en esta población, especialmente, ya que las características clínicas y desenlaces son desconocidos.The age average of patients requiring hospitalization and intensive unit care management is growing, that responds to the increased life expectation and better clinical, technological and pharmacological tools for treatment of these conditions. Thus, more and more cases are observed in the intensive unit care for elderly patients with severe renal compromise and renal replacement therapy requirement. This situation justifies deeper understanding of an acute kidney injurie and renal support in this population, especially since the clinical characteristics and outcomes are not well known.Especialista en GeriatríaEspecializació

    El cáncer es una enfermedad crónica no transmisible, cuya prevalencia va en aumento debido al envejecimiento poblacional. Aproximadamente, el 50% de los diagnósticos nuevos de cáncer ocurren en población mayor de 65 años. Se ha identificado la edad como factor de riesgo para cáncer. Dada la evidencia limitada frente a esquemas de tratamiento respecto a quimioterapia, radioterapia e inmunoterapia en el adulto mayor, se han evidenciado desenlaces adversos derivados de la toxicidad en sistemas como tegumentario, cardiovascular, renal o neurológico, que repercuten en la adherencia al tratamiento y la calidad de vida de los pacientes. En esta primera publicación de la serie de dos para los médicos no oncólogos se tiene como objetivo describir de forma puntual los diversos tipos de toxicidad, para brindar herramientas de detección temprana de síntomas asociados con toxicidad. Palabras clave: geriatría, anciano, toxicidad aguda, toxicidad crónica, quimioterapia, radioterapia, inmunoterapia.Cancer is a chronic non-communicable disease, whose prevalence is increasing due to population aging. Approximately 50% of new cancer diagnoses occur in the population over 65 years of age, thus age is identified as a risk factor. Given the limited evidence regarding treatment schemes for chemotherapy, radiotherapy and immunotherapy in the elderly, adverse outcomes derived from toxicity in systems such as: integumentary, cardiovascular, renal or neurological have an impact in the adherence to treatment and quality of life of patients. However, these scales have not been validated in Colombia. In this first publication of the series of two publications, the objective is to describe the different types of toxicity to non-oncologists in order to provide tools for early detection of symptoms associated with toxicity secondary to treatment with chemotherapy, radiotherapy and immunotherapy in older adult patients. Keywords: geriatrics, aged, acute toxicity, chronic Toxicity, chemotherapy, radiotherapy, immunotherapy.https://orcid.org/0000-0002-7681-0355https://scholar.google.com/citations?hl=es&user=mfH6dEoAAAAJ&view_op=list_works&sortby=pubdatehttps://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001394336Revista Nacional - IndexadaA1S

    An embedding technique to determine ττ backgrounds in proton-proton collision data

    Get PDF
    An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

    Bose-Einstein correlations of charged hadrons in proton-proton collisions at s\sqrt s = 13 TeV

    Get PDF
    Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at s \sqrt{s} = 13 TeV. The results are based on data collected using the CMS detector at the LHC during runs with a special low-pileup configuration. Three analysis techniques with different degrees of dependence on simulations are used to remove the non-Bose-Einstein background from the correlation functions. All three methods give consistent results. The measured lengths of homogeneity are studied as functions of particle multiplicity as well as average pair transverse momentum and mass. The results are compared with data from both CMS and ATLAS at s \sqrt{s} = 7 TeV, as well as with theoretical predictions.[graphic not available: see fulltext]Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at s=\sqrt{s} = 13 TeV.

    Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

    Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

    Search for dark matter in events with a leptoquark and missing transverse momentum in proton-proton collisions at 13 TeV

    Get PDF
    A search is presented for dark matter in proton-proton collisions at a center-of-mass energy of root s= 13 TeV using events with at least one high transverse momentum (p(T)) muon, at least one high-p(T) jet, and large missing transverse momentum. The data were collected with the CMS detector at the CERN LHC in 2016 and 2017, and correspond to an integrated luminosity of 77.4 fb(-1). In the examined scenario, a pair of scalar leptoquarks is assumed to be produced. One leptoquark decays to a muon and a jet while the other decays to dark matter and low-p(T) standard model particles. The signature for signal events would be significant missing transverse momentum from the dark matter in conjunction with a peak at the leptoquark mass in the invariant mass distribution of the highest p(T) muon and jet. The data are observed to be consistent with the background predicted by the standard model. For the first benchmark scenario considered, dark matter masses up to 500 GeV are excluded for leptoquark masses m(LQ) approximate to 1400 GeV, and up to 300 GeV for m(LQ) approximate to 1500 GeV. For the second benchmark scenario, dark matter masses up to 600 GeV are excluded for m(LQ) approximate to 1400 GeV. (C) 2019 The Author(s). Published by Elsevier B.V.Peer reviewe

    Search for an L-mu - L-tau gauge boson using Z -> 4 mu events in proton-proton collisions at root s=13 TeV

    A search for a narrow Z' gauge boson with a mass between 5 and 70 GeV resulting from an L-mu - L-tau U (1) local gauge symmetry is reported. Theories that predict such a particle have been proposed as an explanation of various experimental discrepancies, including the lack of a dark matter signal in direct-detection experiments, tension in the measurement of the anomalous magnetic moment of the muon, and reports of possible lepton flavor universality violation in B meson decays. A data sample of proton-proton collisions at a center-of-mass energy of 13 TeV is used, corresponding to an integrated luminosity of 77.3 fb(-1) recorded in 2016 and 2017 by the CMS detector at the LHC. Events containing four muons with an invariant mass near the standard model Z boson mass are analyzed, and the selection is further optimized to be sensitive to the events that may contain Z -> Z'mu mu -> 4 mu decays. The event yields are consistent with the standard model predictions. Upper limits of 10(-8)-10(-7) at 95% confidence level are set on the product of branching fractions B(Z -> Z'mu mu)B(Z' -> mu mu), depending on the Z' mass, which excludes a Z' boson coupling strength to muons above 0.004-0.3. These are the first dedicated limits on L-mu - L-tau models at the LHC and result in a significant increase in the excluded model parameter space. The results of this search may also be used to constrain the coupling strength of any light Z' gauge boson to muons. (C) 2019 The Author(s). Published by Elsevier B.V.Peer reviewe
