  1. 21. Traumatic brain injury in elderly patients

    Författare :Samuel Lenell; Per Enblad; Anders Lewén; Alfonso Lagares; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Elderly; Outcome; Standardized neurosurgical intensive care; Quality register; Prognostic factors; Secondary insults; Neurointensive care monitoring; Pressure reactivity index; Optimal cerebral perfusion pressure; Cerebral autoregulation; Neurokirurgi; Neurosurgery;

    Sammanfattning : The increase of elderly traumatic brain injury (TBI) patients constitutes a considerable challenge. The aim was therefore to specifically study elderly TBI patients with respect to patient characteristics, neurointensive care (NIC) and outcome, and to identify age specific features, which may be important for selection of patients and optimization of NIC in the elderly.

  3. 22. Knee function, knee proprioception and related brain activity following anterior cruciate ligament injury

    Författare :Andrew Strong; Charlotte Häger; Eva Tengman; Divya Srinivasan; Eleni Kapreli; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; knee; proprioception; joint position sense; kinematics; injury prevention; sports; functional magnetic resonance imaging; brain; reliability; validity; sjukgymnastik; Physiotherapy; Sports Medicine; idrottsmedicin; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : Background: Injury of the anterior cruciate ligament (ACL) may have negative effects on the short- and long-term function and proprioception of the knee joint. However, existing tests of knee function are often sports-related and less relevant for assessment in the very long term and there remains no ‘gold standard’ test of knee proprioception. LÄS MER

  4. 23. Diving and the brain

    Författare :Anders Rosén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; brain; central nervous system; decompression sickness; dive research; diving; neuronal damage; saturation diving; tau protein; venous gas embolism; neurofilament light; glial fibrillary acid protein; tau; VGE;

    Sammanfattning : Abstract Introduction There are reports that long-term diving is associated with cognitive impairments. This raises the question if diving itself is harmful to the brain in the absence of decompression sickness or hypoxia. LÄS MER

  5. 24. Physical Modeling of Brain and Head Kinematics

    Författare :Johan Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

  7. 25. Reanalysis of primate head impact experiments to clarify mild traumatic brain injury kinematics and thresholds

    Författare :Jacobo Antona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; Brain; finite element; injury criteria;

    Sammanfattning : Fatalities and severe injuries due to road traffic accidents still represent a serious health and economic issue intoday’s society. Brain injuries are the most common severe injuries and these injuries account for more than half ofthe 1.3 million traffic related deaths annually worldwide. LÄS MER
