A cadeira de rodas e seus componentes essenciais para a locomoção de pessoas com tetraplegia por lesão da medula espinhal

Objetivo: Compreender quais itens são essenciais à cadeira de rodas (CR) na perspectiva da pessoa tetraplégica por lesão da medula espinhal (LME). Método: O estudo qualitativo foi com entrevista semi-estruturada e análise de discurso, bem como, checklist da CR em uso e do Sistema Único de Saúde (SUS). Resultados: No total foram dez entrevistados: nove homens e uma mulher, média de idade de 42,3 anos (± 9,23), dois advogados, um economista e demais aposentados. As causas da LME foram acidente automobilístico (60%), mergulho em águas rasas (30%) e atropelamento (10%), respectivamente. O tempo de lesão foi em média 16,3 anos (± 7,14) e todos realizavam fisioterapia. Os números de CR, até a adequada, foram duas a cinco e todos praticavam esporte adaptado ou lazer com CR. O checklist apontou itens insuficientes na CR do SUS e da análise dos discursos resultaram em quatro categorias: Itens, materiais e condições necessárias; A conquista da funcionalidade; Vantagens e desvantagens da CR; e Sentimentos vivenciados. A CR é essencial para a locomoção das pessoas com tetraplegia e conhecer modelos, experimentar e ter orientações sobre os itens adequados são importantes para a aquisição. Os itens adequados facilitam a aceitação, melhor adaptação, locomoção e autonomia. Conclusão: A cadeira do SUS mostrou-se insuficiente, o que leva ao abandono. A adquirida por funcionalidade, com itens essenciais, o que responde a individualidade e ao gosto do usuário, mostrou-se útil e adequada apesar de seu elevado custo.Objective: This study sought to understand which items are essential to the wheelchair from the perspective of a person with quadriplegic spinal cord injury (SCI). Method: The study was qualitative with semi-structured interviews and discourse analysis, as well as a checklist of the wheelchair being used and the wheelchair provided by the government’s Unified Health System (SUS). Results: The causes of SCI were motor vehicle accidents (60%), diving into shallow waters (30%) and being struck by a vehicle (10%), respectively and the injury time averaged 16.3 years (± 7.14). All of the subjects were in physiotherapy. The number of wheelchairs tested before finding the proper one were two to five and some participants practiced adapted sports with the wheelchair. The checklist showed that the government wheelchair had insufficient items and the discourse analysis resulted in four categories: Items, materials, and conditions; Learning functionality; Advantages and disadvantages of the wheelchair; and Feelings experienced. The wheelchair is essential to acquiring mobility for people with quadriplegia and trying out different models and getting orientation on the items are important for their acquisition. Suitable items facilitate acceptance, better adaptation, mobility and enable autonomy. Conclusion: The wheelchair from the government’s health system was insufficient, leading to its being abandoned, and wheelchairs acquired for their functionality, with essential items, responsive to the user’s individuality and taste proved to be useful and appropriate, despite their high cost

Estudo sobre as características da dor em pacientes com lesão medular

Além da perda da funcionalidade após a lesão medular (LM), a dor é tida como uma das principais complicações mais incapacitantes e vivenciadas no processo de reabilitação, mesmo com o avanço significativo na compreensão da fisiopatologia e tratamento da dor, a abordagem desse sintoma ainda é precária na lesão medular. Objetivo: Descrever as características do quadro álgico nessa população e associar a dor com o tipo de lesão, interferência nas atividades de vida diária (AVD’s) e o seu aparecimento. Método: Trata-se de estudo transversal com um roteiro de entrevista semiestruturado aplicado a 77 pacientes. Foram calculadas a média e desvio padrão, frequências absolutas e relativas, para a associação entre as variáveis qualitativas foi utilizado teste Qui-quadrado (χ²). Resultados: A idade foi de 38,26 ± 12,43 anos, sendo 84,4% homens e 80,5% de paraplégicos. Trinta e um foram por acidente automobilístico e 29 por ferimento de arma de fogo, sendo 61,0% com lesão medular completa. Quanto à dor, 44,2% relataram dor severa e 29,8% a moderada, em 50,6% não sentiam dor acima da lesão e 58,4% sentiam-na abaixo. Trinta e nove relataram sentir dor em queimação, 40,0% relataram que a dor surgiu no primeiro ano após a LM. A intensidade da dor foi de 5,44 ± 3,18 pontos, sendo 5,20 ± 3,07 nos homens, 6,75 ± 3,54 nas mulheres, 4,13 ± 3,18 nos tetraplégicos e 5,76 ± 3,12 nos paraplégicos. Para 27 pacientes a dor piorou permanecendo na mesma posição, para 22 melhorou realizando fisioterapia e para 21 com a mudança de posição. Para 68,8% a dor não interferiu nas AVD’s. Vinte e oito utilizaram medicação analgésica. Houve associação significativa de que a presença de dor abaixo da lesão interfere nas AVD’s (p = 0,04) e surge no primeiro ano após a lesão acima e abaixo da lesão (p = 0,05 e p = 0,01), respectivamente. Conclusão: A dor foi prevalente nos lesados medulares, mais evidenciada nas mulheres e na maioria surgiu no primeiro ano após a lesão e interfere AVD’s. A fisioterapia e a mudança de posição diminuíram a dor. Portanto, as orientações e intervenções por parte da equipe multiprofissional devem ser imediatas após a lesão, pois a prevenção ou diminuição desta complicação refletirá na melhoria da qualidade de vida e na readaptação do paciente à sua vida familiar e social.Aside from the loss of functionality after a spinal cord injury (SCI) pain is considered one of the most disabling complications experienced in the rehabilitation process, even with the significant advances in understanding the physiopathology and treatment of the pain, the approach to this symptom is still precarious in spinal cord injury. Objective: To describe the characteristics of pain in this population and to associate the pain between variables such as the type of injury, the interference in the daily living activities (DLA), and its onset. Method: It is a descriptive cross-sectional study and was conducted on 77 patients with spinal cord injuries; the survey was applied using a semi-structured interview. Mean and standard deviation and absolute and relative frequencies were calculated, and for the association between qualitative variables we used the Chisquare test (χ²). Results: The mean age was 38.26 ± 12.43 years, 84.4% of which were men, and 80.5% were paraplegics. Thirty-one were caused by motor vehicle crashes and twenty-nine were by gunshot; 61% of them were fully disabled. As for the pain, 44.2% reported severe pain and 29.8% moderate, 50.6% felt no pain above the lesion, but 58.4% felt it below. Thirty-nine patients reported feeling burning pain, 40% reported that the pain came in the first year after SCI. Pain intensity was 5.44 ± 3.18 points, with 5.20 ± 3.07 in men and 6.75 ± 3.54 in women; for tetraplegic individuals it was 4.13 ± 3.18 and with 5.76 ± 3.12 in the paraplegics. For 27 patients the pain worsened if they remained in the same position, improved to 22 by performing physiotherapy, and to 21 with a change in position. For 68.8% of the patients the pain did not interfere with their DLAs. Twenty-eight used analgesics. It was significantly mentioned that the presence of pain below the lesion interferes with the DLAs (p = 0.04) and appears in the first year after injury above and below the lesion (p = 0.05 and p = 0.01), respectively. Conclusion: Pain was prevalent in those with injured spinal cords, more evident in women, and for the majority arose in the first year after injury and interferes with their DLA. Physiotherapy and a change of position decreased the pain. Therefore, orientations and interventions by the multidisciplinary team should be immediate after the injury, because the prevention or reduction of this complication will lead to an improved quality of life and the re-adaptation of the patient to their family and social life

Sexual profile and adaptations of men after spinal cord injury

Lesão medular (LM) consiste em qualquer tipo de lesão nos elementos neurais do canal medular, acarretando inúmeros comprometimentos, sendo a alteração nos padrões da resposta sexual um deles, condicionada por fatores físicos, psíquicos e sociais. Em função destas alterações, os pacientes necessitam realizar adaptações sexuais para manterem a atividade sexual. Objetivo: Verificar o perfil e adaptações sexuais de homens após a LM e associar o diagnóstico neurofuncional com frequência sexual, ereção, uso de adaptação, tipo de adaptação, e a utilização de adaptação com frequência e satisfação sexual após a lesão. Método: Trata-se de um estudo transversal com 36 homens lesados medulares que foram entrevistados por meio do questionário (QSH-LM). Resultados: Média de idade é 36,64 anos com prevalência decorrente de acidente de trânsito, de paraplegia e de lesão medular completa. Após a LM, 52,8% estão casados, 75,5% mantém atividade sexual sendo que 44,4% têm menos de 1 relação sexual/semana, 80,6% estão satisfeitos sexualmente, 50,0% têm ereção, 38,9% ejaculação e 44,4% orgasmo. Quanto ao uso de adaptação para ter/manter a ereção, 61,1% utilizam, sendo 25,5% por não conseguirem manter a ereção e 22% optam pelo anel peniano. Houve associação significativa de que paraplégicos utilizam adaptações com mais frequência e preferem o anel peniano e pacientes que utilizam adaptação sexual tem maior frequência sexual e estão satisfeitos sexualmente (p = 0,02). Conclusão: Através deste trabalho podem-se conhecer o perfil sexual dos pacientes após a LM e as adaptações sexuais mais utilizadas, resultados que subsidiam informações que poderão auxiliar os profissionais de saúde a acompanharem e orientarem de maneira adequada os seus pacientes.Spinal cord injury (SCI) refers to any type of injury to the neural elements of the spinal canal, resulting in countless damages, one of them being the change in patterns of sexual response, conditioned by physical, psychological, and social aspects. Due to these changes, patients need to make adjustments to maintain sexual activity. Objective: To verify the sexual profile and adaptations of men after SCI and to associate the neurofunctional diagnosis with sexual frequency, erection, use and type of adaptation, and the use of adaptation with sexual frequency and sexual satisfaction. Method: Cross-sectional study with 36 men with spinal cord injuries. They were interviewed with the (QSH-LM) questionnaire. Results: The mean age was 36.64 years old with the majority of injuries stemming from traffic accidents, resulting in paraplegia or complete injury. After the SCI, 52.8% of the subjects remained married, 75.5% maintained sexual activity, whereas 44.4% have less than one intercourse/week, 80.6% are sexually satisfied, 50% have erection, 38.9% ejaculation, and 44.4% orgasm. Regarding the use of adaptations to achieve and maintain an erection, 61.1% of the subjects use them, 25.5% because they fail to maintain an erection and 22% have opted for the penis ring. There was a significant association between paraplegics who use adjustments more frequently and prefer the penis ring and patients who use sexual adaptations having greater sexual frequency and being sexually satisfied (p = 0.02). Conclusion: Through this work it is possible to know the sexual profile of patients after SCI and the most used sexual adaptations. These results support the information that might assist healthcare professionals to monitor and guide their patients properly

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.

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat

Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe

Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

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

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
