Hanseníase e Fisioterapia: uma abordagem necessária

Introduction: New cases of leprosy occur due to a set of factors associated with the lack of knowledge about the disease, both by health professionals and patients, favoring late diagnosis, the development of physical and social disabilities, stigma and prejudice. Objective: To verify the knowledge of students completing the physiotherapy course on leprosy and professional practice in the care of patients with the disease. Methods: A qualitative exploratory descriptive study was conducted with 68 undergraduate students from physiotherapy courses from public and private universities (AU, UB, UC), in the State of Mato Grosso do Sul. Data were collected through a questionnaire with ten open questions about knowledge, practical action, motivations, interests and teaching-learning process about leprosy. To organize and analyze the data, thecollective subject discourse technique was used.  Results: It was found that 60% of aU students, 63% of UB and 30.8% of UC have a general conception about the disease. 46.7% of aU students, 77.8% of UB and 80.9% of UC never had contact with leprosy patients. More than half of the students at the three universities said they were unaware of the physiotherapy approaches and practices in leprosy. Almost 100% of ub and UC students stated that the subject was not addressed during the course and therefore did not feel prepared to provide health education and to guide on how to prevent physical deficiencies resulting from leprosy. 73.3% of AU students, 96.3% of UB and 100% of UC recorded negative evaluations, qualifying the course as precarious, insufficient and weak in the leprosy approach. Conclusion: It is concluded that leprosy should be included in physiotherapy courses systematically, providing practical care activities, developing skills from prevention to rehabilitation, seeking greater motivation and identification of his work in this area.Introdução: Novos casos de hanseníase ocorrem devido a um conjunto de fatores associados à falta de conhecimento sobre a doença, tanto pelos profissionais de saúde quanto pelos pacientes, favorecendo o diagnóstico tardio, o desenvolvimento de incapacidades físicas e sociais, o estigma e o preconceito. Objetivo: verificar o conhecimento de estudantes concluintes do curso de fisioterapia sobre hanseníase e a prática profissional no cuidado ao paciente com a doença. Método: Realizou-se um estudo descritivo exploratório qualitativo com 68 estudantes de graduação dos cursos de fisioterapia de universidades públicas e privadas (UA, UB, UC), no Estado de Mato Grosso do Sul. Os dados foram coletados por meio de questionário com dez perguntas abertas sobre conhecimento, ação prática, motivações, interesses e processo de ensino-aprendizagem sobre a hanseníase. Para organizar e analisar os dados, utilizou-se a técnica do Discurso do Sujeito Coletivo. Resultados: Encontrou-se que 60% dos estudantes de UA, 63% de UB e 30,8% de UC têm concepção geral sobre a doença. 46,7% dos estudantes da UA, 77,8% da UB e 80,9% da UC nunca tiveram contato com pacientes com hanseníase. Mais da metade dos estudantes das três universidades disseram não ter conhecimento das abordagens e práticas fisioterápicas em hanseníase. Quase 100% dos estudantes de UB e UC declararam que o assunto não foi abordado durante o curso e, portanto, não se sentiram preparados para fornecer educação em saúde e para orientar em como prevenir deficiências físicas resultantes da hanseníase. 73,3% dos estudantes da UA, 96,3% da UB e 100% da UC registraram avaliações negativas, qualificando o curso como precário, insuficiente e fraco na abordagem da hanseníase. Conclusão: Conclui-se que a hanseníase deve ser incluída nos cursos de fisioterapia de forma sistemática, proporcionando atividades práticas de cuidado, desenvolvendo habilidades desde a prevenção até a reabilitação, buscando maior motivação e identificação de seu trabalho nessa área

Light-front holographic QCD and emerging confinement

In this report we explore the remarkable connections between light-front dynamics, its holographic mapping to gravity in a higher-dimensional anti-de Sitter (AdS) space, and conformal quantum mechanics. This approach provides new insights into the origin of a fundamental mass scale and the physics underlying confinement dynamics in QCD in the limit of massless quarks. The result is a relativistic light-front wave equation for arbitrary spin with an effective confinement potential derived from a conformal action and its embedding in AdS space. This equation allows for the computation of essential features of hadron spectra in terms of a single scale. The light-front holographic methods described here give a precise interpretation of holographic variables and quantities in AdS space in terms of light-front variables and quantum numbers. This leads to a relation between the AdS wave functions and the boost-invariant light-front wave functions describing the internal structure of hadronic bound-states in physical space-time. The pion is massless in the chiral limit and the excitation spectra of relativistic light-quark meson and baryon bound states lie on linear Regge trajectories with identical slopes in the radial and orbital quantum numbers. In the light-front holographic approach described here currents are expressed as an infinite sum of poles, and form factors as a product of poles. At large q(2) the form factor incorporates the correct power-law fall-off for hard scattering independent of the specific dynamics and is dictated by the twist. At low q2 the form factor leads to vector dominance. The approach is also extended to include small quark masses. We briefly review in this report other holographic approaches to QCD, in particular top-down and bottom-up models based on chiral symmetry breaking. We also include a discussion of open problems and future applications. (C)) 2015 Elsevier B.V. All rights reserved

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Measurement of the W gamma Production Cross Section in Proton-Proton Collisions at root s=13 TeV and Constraints on Effective Field Theory Coefficients

A fiducial cross section for W gamma production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb(-1) of data collected using the CMS detector at the LHC. The W -> e nu and mu nu decay modes are used in a maximum-likelihood fit to the lepton-photon invariant mass distribution to extract the combined cross section. The measured cross section is compared with theoretical expectations at next-to-leading order in quantum chromodynamics. In addition, 95% confidence level intervals are reported for anomalous triple-gauge couplings within the framework of effective field theory.Peer reviewe

Search for top squark production in fully hadronic final states in proton-proton collisions at root s=13 TeV

A search for production of the supersymmetric partners of the top quark, top squarks, is presented. The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 137 fb(-1). The targeted signal production scenarios are direct and gluino-mediated top squark production, including scenarios in which the top squark and neutralino masses are nearly degenerate. The search utilizes novel algorithms based on deep neural networks that identify hadronically decaying top quarks and W bosons, which are expected in many of the targeted signal models. No statistically significant excess of events is observed relative to the expectation from the standard model, and limits on the top squark production cross section are obtained in the context of simplified supersymmetric models for various production and decay modes. Exclusion limits as high as 1310 GeVare established at the 95% confidence level on the mass of the top squark for direct top squark production models, and as high as 2260 GeV on the mass of the gluino for gluino-mediated top squark production models. These results represent a significant improvement over the results of previous searches for supersymmetry by CMS in the same final state.Peer reviewe

Observation of tW production in the single-lepton channel in pp collisions at root s=13 TeV

A measurement of the cross section of the associated production of a single top quark and a W boson in final states with a muon or electron and jets in proton-proton collisions at root s = 13 TeV is presented. The data correspond to an integrated luminosity of 36 fb(-1) collected with the CMS detector at the CERN LHC in 2016. A boosted decision tree is used to separate the tW signal from the dominant t (t) over bar background, whilst the subleading W+jets and multijet backgrounds are constrained using data-based estimates. This result is the first observation of the tW process in final states containing a muon or electron and jets, with a significance exceeding 5 standard deviations. The cross section is determined to be 89 +/- 4 (stat) +/- 12 (syst) pb, consistent with the standard model.Peer reviewe
