Os desafios do atendimento de pacientes com sequelas cardiovasculares decorrentes de trauma do tórax / Challenges in the care of patients with cardiovascular sequels resulting from chest trauma

Introdução: O tórax apresenta estruturas de diversos sistemas de sustentação da vida, dentre eles o respiratório e o cardiovascular. Por conter, estruturas nobres para a manutenção da vida, os potenciais para ocorrer lesões graves em decorrência de traumas são muito grandes, como dados mostram, 25% das mortes são secundárias a trauma torácico. Dentro deste contexto, questiona-se quais os desafios no atendimento de pacientes com sequelas cardiovasculares decorrentes de traumas torácicos? Portanto, esse estudo tem como objetivo identificar as dificuldades enfrentadas na assistência de saúde de pacientes com repercussões cardiovasculares devido a trauma de tórax, através da elaboração de um formulário baseado em revisão bibliográfica de dados da literatura científica publicados sobre esse tema. Metodologia: O trabalho baseia-se numa revisão integrativa de literatura, na qual foram analisados artigos publicados em revistas científicas, utilizando-se das bases de dados da BVS (Biblioteca Virtual da Saúde), como: Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Scielo (Scientific Electronic Library Online). Resultados: Após as análises e seleção, restaram-se sete artigos para integrar a discussão. Os artigos selecionados, estão descritos na tabela, com autores, título, metodologia, resultados e conclusão. Em seguida, foi realizada uma discussão acerca destes artigos. Conclusão: Cada um dos casos revisados neste estudo demonstra a necessidade e a importância de acompanhamento cuidadoso de todos os pacientes que sofreram trauma torácico fechado, mesmo que a avaliação cardíaca inicial possa ser negativa.

Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton-proton collisions at the LHC

This paper presents the method and performance of primary vertex reconstruction in proton-proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during 2012 at a centre-of-mass energy of [Formula: see text] TeV. The performance has been measured as a function of the number of interactions per bunch crossing over a wide range, from one to seventy. The measurement of the position and size of the luminous region and its use as a constraint to improve the primary vertex resolution are discussed. A longitudinal vertex position resolution of about [Formula: see text] is achieved for events with high multiplicity of reconstructed tracks. The transverse position resolution is better than [Formula: see text] and is dominated by the precision on the size of the luminous region. An analytical model is proposed to describe the primary vertex reconstruction efficiency as a function of the number of interactions per bunch crossing and of the longitudinal size of the luminous region. Agreement between the data and the predictions of this model is better than 3% up to seventy interactions per bunch crossing

Search for Scalar Diphoton Resonances in the Mass Range 65−60065-600 GeV with the ATLAS Detector in pppp Collision Data at s\sqrt{s} = 8 TeVTeV

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using $20.3\text{}\text{}{\mathrm{fb}}^{-1}$ of $\sqrt{s}=8\text{}\text{}\mathrm{TeV}$ $pp$ collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches

Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H??????? and H???ZZ*???4??? Decay Channels at s\sqrt{s}=8??????TeV with the ATLAS Detector

Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3~fb$^{-1}$ of $pp$ collisions produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = 8$ TeV and recorded by the ATLAS detector. Cross sections are obtained from measured $H \rightarrow \gamma \gamma$ and $H \rightarrow ZZ ^{*}\rightarrow 4\ell$ event yields, which are combined accounting for detector efficiencies, fiducial acceptances and branching fractions. Differential cross sections are reported as a function of Higgs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transverse momentum of the leading jet. The total production cross section is determined to be $\sigma_{pp \to H} = 33.0 \pm 5.3 \, ({\rm stat}) \pm 1.6 \, ({\rm sys}) \mathrm{pb}$. The measurements are compared to state-of-the-art predictions.Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3  fb-1 of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of s=8  TeV and recorded by the ATLAS detector.
