    BackgroundThe purpose of this study was to identify the possible needs for undergraduate disaster medicine education in Sweden and to make informed recommendations for the implementation of disaster medicine content in medical and nursing schools in Sweden.MethodsAn online survey was distributed to undergraduate medical and nursing students through the directors of all medical and nursing programs at Swedish universities. The survey contained demographic questions, as well as questions about the amount of disaster medical education and previous experience with rescue, police, or military services. The final survey page contained self-assessments of disaster medical knowledge. Comparative statistics were applied between nursing and medical students, those with previous military service, and those without, as well as between universities.ResultsA total of 500 medical and 408 nursing students participated in this study. A median of 2 h of disaster medicine education was provided to senior medical students and 4 h was provided to senior nursing students. Senior medical students scored their disaster medical knowledge lower than nursing students (t-test, p < 0.001). A proportion of 1% had served in rescue services or police, and 7% of the participants had a history of military service, of which 67% served in a medical role. Those who had served in rescue services, police, or the armed forces had a higher self-assessed disaster medical knowledge base than those who had not (p < 0.007 and p < 0.001, respectively).ConclusionMost medical and nursing students in this study rated their disaster medical knowledge as insufficient. The correlation between the amount of disaster medical education and self-assessed disaster medical knowledge should influence and help direct Swedish educational policies

    C1 Lateral Mass Screw Fixation

    C1 lateral mass screws according to Goel and Harms represent a safe and stable stabilization of the atlas within posterior constructs. Those constructs avoiding transarticular C1-C2 screws allow for different reduction manoeuvers after screw insertion. By preoperative planning, the course of the vertebral artery has to be visualized to avoid potentially disastrous injuries. Proper subperiosteal preparation is necessary to avoid copious bleeding from the venous plexus below the C1 arch. Under lateral visualization, screws can be placed in the C1 lateral mass without the necessity of sacrificing the C2 root. C1 screws should converge about 10–20°, and bicortical screw placement is preferred

    Observability analysis of power distribution systems with distributed energy resources using correlational measurements

    Thesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2019Cataloged from PDF version of thesis.Includes bibliographical references (pages 57-59).In this thesis, an observability analysis framework is proposed for power distribution systems. The framework analyzes the sufficiency of the available measurements for monitoring the system. In the areas of the network where sufficient sensors have been deployed, the complex voltage at the nodes may be estimated. The framework also provides a metric that quantifies the accuracy of these voltage estimates. Due to the cost of sensors and the size of distribution systems, it is frequently the case that the available measurements are insufficient for complete observability of the system. In this thesis, the author proposes the use of Correlational Measurements (CMs) for improving distribution system observability by leveraging correlation between loads and between Distributed Energy Resources (DERs). Load correlation due to class-residential, commercial, industrial, etc.- is captured via correlational load measurements, the first type of CM. Injection correlation of DERs-such as wind turbines located in proximity-is captured via correlational DER measurements, the second type of CM. This thesis presents the CM formulation and derives modified node voltage and branch current based state estimators (NVSE and BCSE) accommodating CMs. Additionally, this thesis contains an on-line parameter estimation scheme for CMs that improves the accuracy of state estimates over time. The observability analysis framework with CMs is demonstrated through simulations on the IEEE 123 Node Distribution Test Feeder. It is shown that the introduction of CMs leads to improved observability of the system with only a 0.7% decrease in state estimation accuracy for NVSE and a 0.5% increase in state estimation accuracy for BCSE.by Yohan M.

    Kotfrakturincidensen ökar hos patienter med ankyloserande spondylit

    Sammanfattningsvis kunde en ökad incidens av kotfrakturer vid ankyloserande spondylit hittas de senaste två decennierna, och detta trots förbättrad medicinsk terapi. Därmed fortsätter restriktionerna vad gäller fysisk aktivitet för patienter med ankyloserande spondylit att gälla även i dag (tabell 1). Vi måste därför informera våra patienter om att det kan finnas typiska biomekaniska påfrestningar även vid subjektiv symtomfrihet

    Ortopedens roll i kris och krig

    Samhällsdebatten om hälso- och sjukvårdens krisberedskap har nog inte gått någon förbi. Minnen från pandemin, jordbävningen i Turkiet och kriget i Ukraina berör alla. Även Sverige kan konfronteras med kriser och potentiella hot om krig. Hälso- och sjukvården är totalförsvarets kanske mest utmanande sektor. Att ha en välfungerande hälso- och sjukvård för att ta hand om de skadade och sjuka skapar motståndskraft men kräver förberedd personal. Samtliga professioner inom hälso- och sjukvården bidrar till totalförsvarets hälso- och sjukvårdsförmåga. I denna artikel kommer vi att utforska den avgörande roll som ortopeder spelar i kris och krig
