| 1 | Do medical students studying in the United Kingdom have an adequate factual knowledge of basic life support?显示文摘BACKGROUND: Healthcare professionals have a duty to maintain basic life support(BLS) skills. This study aims to evaluate medical students' factual knowledge of BLS and the training they receive.METHODS: A cross-sectional, closed-response questionnaire was distributed to the fi rst-and fourth-year students studying at institutions in the United Kingdom. The paper questionnaire sought to quantify respondent's previous BLS training, factual knowledge of the BLS algorithm using five multiple choice questions(MCQs), and valuate their desire for further BLS training. Students received 1 point for each correctly identifi ed answer to the 5 MCQ's.RESULTS: A total of 3,732 complete responses were received from 21 medical schools. Eighty percent(n=2,999) of students completed a BLS course as part of their undergraduate medical studies. There was a signifi cant difference(P<0.001) in the percentage of the fourth-year students selecting the correct answer in all the MCQ's compared to the fi rst-year students except in identifyingthe correct depth of compressions required during CPR(P=0.095). Overall 10.3%(95% CI 9.9% to 10.7%) of respondents correctly identified the answer to 5 MCQ's on BLS: 9% of the first-year students(n=194) and 12% of the fourth-year students(n=190). On an institutional level the proportion of students answering all MCQ's correctly ranged from 2% to 54% at different universities. Eighty-one percent of students(n=3,031) wished for more BLS training in their curriculum.CONCLUSION: Factual knowledge of BLS is poor among medical students in the UK. There is a disparity in standards of knowledge across institutions and respondents indicating that they would like more training. | Robert D.Willmore Damjan Veljanoski Feray Ozdes Bethan Stephens James Mooney Seamus G.Crumley Arpan Doshi Philippa Davies Shreya Badhrinarayanan Emily Day Kristian Tattam April Wilson Nathan Crang Lorna Green Craig A.Mounsey Howell Fu Joseph Williams Michelle S.D'souza Dhanya Sebastian Liam A.Mcgiveron Matthew G.Percy James Cohen Imogen J.John Alice Lethbridge Imogen Watkins Omar Amin Mubasher A.Qamar John Gerrard Hanrahan Emily Cramond-Wong | 2019 | World Journal of Emergency Medicine2019，10，2： | 2 |
| 2 | Propagation of Ion Solitary Pulses in Dense Astrophysical Electron-Positron-Ion Magnetoplasmas显示文摘In this paper,we theoretically investigate the existence and propagation of low amplitude nonlinear ion waves in a dense plasma under the influence of a strong magnetic field.The plasma consists of ultra-relativistic and degenerate electrons and positrons and non-degenerate cold ions.Firstly,the appearance of two distinct linear modes and their evolution is studied by deriving a dispersion equation with the aid of Fourier analysis.Secondly,the dynamics of low amplitude ion solitary structures is investigated via a Korteweg-de Vries equation derived by employing a reductive perturbation method.The effects of various plasma parameters like positron concentration,strength of magnetic field,obliqueness of field,etc.,are discussed in detail.At the end,analytical results are supplemented through numerical analysis by using typical representative parameters consistent with degenerate and ultra-relativistic magnetoplasmas of astrophysical regimes. | ATA-UR-RAHMAN S.A.KHAN A.QAMAR | 2015 | Plasma Science and Technology2015，17，12： | 0 |
