    Hintergrund: Herz-Kreislauf-Erkrankungen sind in der Schweiz ein häufiger Einweisungsgrund ins Spital. Vordergründige Probleme bei offenen Herzoperationen sind Angst, Stress und die Stabilisierung der Vitalparameter wie Blutdruck, Herzfrequenz oder Atmung. Ziel: Ziel dieser Bachelorarbeit ist es herauszufinden, was das postoperative Hören von Musik bei Patienten, welche sich im Akutspital einer elektiv offenen Herzoperation unterzogen haben bewirkt. Zusätzlich sollen Möglichkeiten für den zukünftigen Einsatz von Musik im Akutspital aufgezeigt werden. Methode: Eine systematische Literaturrecherche wurde in den Datenbanken Medline, CINAHL, PsycINFO, Web of Science Portal, PubMed, IBSS, AMED und PubPsych durchgeführt und anschliessend analysiert, bewertet und verglichen. Ergebnisse: Die sechs verwendeten Studien zeigen auf, dass sich Musikmedizin positiv auf Schmerzen und Angst auswirkt. Auf den Blutdruck und die Herzfrequenz hat Musikmedizin keine Auswirkung. Die Atemfrequenz kann durch Musik beeinflusst werden, bewirkt aber keine Veränderung der Sauerstoffsättigung und des Sauerstoffpartialdrucks. In Bezug auf die Variablen s-Cortisol, s-Oxytocin und Entspannungslevel sind sich die Studien uneins. Schlussfolgerung: Musikhören nach einer elektiv offenen Herzoperation hat keine unerwünschten Nebenwirkungen. Zudem zeigen sich positive Auswirkungen auf die oben aufgeführten Variablen. Musikmedizin ist wirtschaftlich und einfach in der Durchführung, deshalb empfehlen die Autorinnen diese Intervention in die Praxis zu implementieren

    Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

    A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

    Measurements of the Higgs boson production and decay rates and coupling strengths using pp collision data at √S=7 and 8 TeV in the ATLAS experiment

    Combined analyses of the Higgs boson production and decay rates as well as its coupling strengths to vector bosons and fermions are presented. The combinations include the results of the analyses of the H -> gamma gamma, ZZ*, WW*, Z gamma, b (b) over bar, tau tau and mu mu decay modes, and the constraints on the associated production with a pair of top quarks and on the off-shell coupling strengths of the Higgs boson. The results are based on the LHC proton-proton collision datasets, with integrated luminosities of up to 4.7 fb(-1) at root s = 7 TeV and 20.3 fb(-1) at root s = 8 TeV, recorded by the ATLAS detector in 2011 and 2012. Combining all production modes and decay channels, the measured signal yield, normalised to the Standard Model expectation, is 1.18(-0.14)(+0.15). The observed Higgs boson production and decay rates are interpreted in a leading-order coupling framework, exploring a wide range of benchmark coupling models both with and without assumptions on the Higgs boson width and on the Standard Model particle content in loop processes. The data are found to be compatible with the Standard Model expectations for a Higgs boson at a mass of 125.36 GeV for all models considered
