  1. 1. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries

    Författare :Johan Thorfinn; Disa Lidman; Folke Sjöberg; Henry Svensson; Linköpings universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Blood supply; Buttocks; Hyperemia; Ischemia; Laser-Doppler flowmetry; Microcirculation; Posture physiology; Pressure; Skin blood supply; Medicine; Medicin;

    Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER

  2. 2. Blood saving in orthopaedic surgery

    Författare :Jan Widman; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : A substantial blood loss frequently accompanies total hip and knee replacement surgery. This is a potential health risk and associated with increased need for allogenic blood transfusions. LÄS MER

  3. 3. Effects of Ischaemia on the Neuroretina and Retinal Blood Vessels

    Författare :Bodil Gesslein; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein kinase C; tumor necrosis factor; mitogen-activated protein kinases; pig; blood vessels; mfERG; Retinal ischaemia; vascular endothelial growth factor; hypoxia-inducible factor;

    Sammanfattning : Identification of the intracellular signal transduction pathways activated in retinal ischaemia may be important in revealing novel pharmacological targets. The retinal blood vessels are key organs in circulatory failure, and in this work the retinal vasculature was therefore examined separately from the neuroretina. LÄS MER

  4. 4. On the nature and etiology of chronic achilles tendinopathy

    Författare :Mats Åström; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gender; physical activity; aging; imaging; malalignment; blood supply; partial rupture; tendinosis; chronic tendinopathy; Achilles tendon; achillodynia; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : The present studies included 362 consecutive patients and 147 healthy controls and were conducted to provide a rational basis for treatment and future research. The major lesion was a focal non-inflammatory tendon degeneration (tendinosis). Twenty per cent of the cases were complicated by a secondary partial rupture. The paratenon was normal. LÄS MER

  5. 5. Ultrasound based shear wave elastography of the liver : a non-invasive method for evaluation of liver disease

    Författare :Marie Byenfeldt; Anders Elvin; Per Fransson; Odd Helge Gilja; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometric measurement; diagnostic imaging; elasticity imaging technique; blood supply; BMI; body position; fatty liver; liver disease; hepatic steatosis; liver fibrosis; liver stiffness; obesity; postural change; pressure; probe; sex characteristic; shear wave elastography; skin-to-liver capsule distance; transducer and ultrasonography; Radiography; radiografi;

    Sammanfattning : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. LÄS MER
