    Nurses perform a number of tasks daily, sometimes using inappropriate footwear. Using appropriate work shoes is essential to prevent lower extremity musculoskeletal injuries. Objective: Determine individual and work related risk factors as associated to the footwear in a population of nursing workers in a level II health institution. Methodology: Descriptive, crosssectional study in 60 workers of the nursing assistance area level 2 Hospital of Popayan, Colombia. We determined the risks associated to in-use footwear in every area of the hospital. We assessed foot/ankle status and characteristics of the footwear used during the workday. Results: Eighty percent and 90% nursing assistants. More than 75% had normal foot. We detected pain in sole and heel (26,7%). Most use a backless slipper type shoes heel (46.7%) and manufactured with synthetic material (61,7%). Forty-five percent perceives safety footwear as poor. Identified risks were: biological and chemical (100%), weight handling (80%), slip and fall (50%) and a mishap when climbing stairs (40%). Conclusions: In-use footwear used might be an occupational risk factor; however, the frequency of musculoskeletal disorders and accidents are not as high as you might expect.Los enfermeros realizan un gran número de tareas diariamente, utilizando en algunas ocasiones el calzado inadecuado.

Objetivo: Determinar los factores de riesgo individual y laboral asociados al uso del calzado en una población de trabajadores en enfermería de una institución de salud. Metodología: Estudio descriptivo, de corte transversal, en 60 trabajadores del área de servicio asistencial de enfermería de un Hospital de nivel 2 de la ciudad de Popayán, Colombia. Se determinó al panorama de riesgos asociados al calzado en cada área del hospital. Se evaluó la condición del pie/tobillo y las características del calzado que utilizan durante su jornada laboral. Resultados: El 80% fueron mujeres, auxiliares de enfermería (90%). El 78,3% poseen pie normal. Se detecto dolor en planta y talón en el 26,7%. La mayoría usan un calzado tipo babucha sin respaldo al talón (46,7%) y fabricado con material sintético (61,7%). El 45% percibe que la seguridad del calzado es mala. El panorama de riesgos se comportó así: biológico y químico (100%), manipulación de cargas (80%), riesgo de caídas y resbalones (50%) y algún percance al subir escaleras (40%). Conclusiones: El calzado utilizado puede ser un factor de riesgo ocupacional; sin embrago, la frecuencia de desórdenes osteomusculares y la accidentalidad no son tan altas como se podría esperar

    Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at root s=8 TeV

    A search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour-changing neutral current interactions. The data sample corresponds to an integrated luminosity of 19.7 fb−1 recorded by the CMS experiment at the LHC in proton-proton collisions at s√=8s=8 TeV. Final states with three leptons (electrons or muons) and at least one jet are investigated. An events yield compatible with tZq standard model production is observed, and the corresponding cross section is measured to be σ(pp → tZq → ℓνbℓ+ℓ−q) = 10− 7+ 8 fb with a significance of 2.4 standard deviations. No presence of flavour-changing neutral current production of tZq is observed. Exclusion limits at 95% confidence level on the branching fractions of a top quark decaying to a Z boson and an up or a charm quark are found to be ℬ(t → Zu) < 0.022% and ℬ(t → Zc) < 0.049%

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Abstract: A measurement of electroweak-induced production of W gamma and two jets is performed, where the W boson decays leptonically. The data used in the analysis correspond to an integrated luminosity of 19.7 fb(-1) collected by the CMS experiment in root s = 8TeV proton-proton collisions produced at the LHC. Candidate events are selected with exactly one muon or electron, missing transverse momentum, one photon, and two jets with large rapidity separation. An excess over the hypothesis of the standard model without electroweak production of W gamma with two jets is observed with a signi fi cance of 2.7 standard deviations. The cross section measured in the fi ducial region is 10.8 +/- 4.1(stat) +/- 3.4(syst) +/- 0. 3(lumi) fb, which is consistent with the standard model electroweak prediction. The total cross section for W gamma in association with two jets in the same fi ducial region is measured to be 23.2 +/- 4.3(stat) +/- 1.7(syst) +/- 0.6(lumi) fb, which is consistent with the standard model prediction from the combination of electroweakand quantum chromodynamics-induced processes. No deviations are observed from the standard model predictions and experimental limits on anomalous quartic gauge couplings integral M,0- 7 /Lambda(4), integral T,0- 2 /Lambda(4), and integral T,5-7/Lambda(4) are set at 95% con fi dence level

    Measurement of transverse momentum relative to dijet systems in PbPb and pp collisions at root s(NN)=2.76 TeV

    An analysis of dijet events in PbPb and pp collisions is performed to explore the properties of energy loss by partons traveling in a quark-gluon plasma. Data are collected at a nucleon-nucleon center-of-mass energy of 2.76 TeV at the LHC. The distribution of transverse momentum (p(T)) surrounding dijet systems is measured by selecting charged particles in different ranges of p(T) and at different angular cones of pseudorapidity and azimuth. The measurement is performed as a function of centrality of the PbPb collisions, the p(T) asymmetry of the jets in the dijet pair, and the distance parameter R used in the anti-k(T) jet clustering algorithm. In events with unbalanced dijets, PbPb collisions show an enhanced multiplicity in the hemisphere of the subleading jet, with the p(T) imbalance compensated by an excess of low-p(T) particles at large angles from the jet axes

    Search for heavy gauge W ' bosons in events with an energetic lepton and large missing transverse momentum at root s=13TeV

    No full text
    A search is presented for W' bosons in events with an electron or muon and large missing transverse momentum, using proton-proton collision data at root s = 13 TeV collected with the CMS detector in 2015 and corresponding to an integrated luminosity of 2.3 fb(-1). No evidence of an excess of events relative to the standard model expectations is observed. For a W' boson described by the sequential standard model, upper limits at 95% confidence level are set on the product of the production cross section and branching fraction and lower limits are established on the new boson mass. Masses below 4.1 TeV are excluded combining electron and muon decay channels, significantly improving upon the results obtained with the 8 TeV data. Exclusion limits at 95% confidence level on the product of the W' production cross section and branching fraction are also derived in combination with the 8 TeV data. Finally, exclusion limits are set for the production of generic W' bosons decaying into this final state using a model-independent approach. (C) 2017 The Author. Published by Elsevier B.V
