  1. 21. Presence of microemboli during haemodialysis and methods to reduce the exposure to microbubbles

    Författare :Forsberg Ulf; Bernd Stegmayr; Per Jonsson; Ingela Fehrman Ekholm; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; in vivo; microemboli; microbubbles; dialyzer; air trap; venous chamber;

    Sammanfattning : Despite chronic dialysis treatment, patients with end stage renal disease undergoing maintenance haemodialysis (HD) remain at a substantially increased risk of morbidity. Previous reports using Doppler ultrasound (DU) during HD have revealed microembolic signals (ME) in the venous circulation. LÄS MER

  3. 22. The Impact of Pancreatic Islet Vascular Heterogeneity on Beta Cell Function and Disease

    Författare :Sara Ullsten; Per-Ola Carlsson; Joey Lau; Sara Bohman; Rebecca L. Hull; Uppsala universitet; []
    Nyckelord :Pancreatic islets; heterogeneity; islet vascularity; blood flow; islet transplantation; islet amyloid; insulitis; type 1 diabetes; beta cell proliferation; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Diabetes Mellitus is a group of complex and heterogeneous metabolic disorders characterized by hyperglycemia. Even though the condition has been extensively studied, its causes and complex pathologies are still not fully understood. The occurring damage to the pancreatic islets is strikingly heterogeneous.

  4. 23. Cerebral perfusion during cardiopulmonary bypass with special reference to blood flow

    Författare :Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Dan Lindblom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cardiopulmonary bypass (CPB) is an important method that enables open heart surgery. There is a risk of neurological complications, and efforts to minimize those include optimization of the cerebral perfusion during CPB. LÄS MER

  5. 24. Central venous access devices in patients with haematological malignancies care, complications and home treatment

    Författare :Eva Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Central venous access devices; haematological malignancies; dressing changes; self-administration; ambulatory; stem cell collection;

    Sammanfattning : A well functioning central venous access device (CVAD) that will remain in situ free from complications during the entire treatment period, is highly desirable in the management of patients with aggressive haematological malignancies. Unfortunately, such a goal is not likely to be achieved due to the high rate of CVAD-related complications. LÄS MER

  7. 25. Venous thrombosis in children : the roles of vascular access and critical illness

    Författare :Åsa Östlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Venous thromboembolism (VT) is a rare event in the general pediatric population. However, the incidence in hospitalized children is higher and has increased dramatically reaching 58 per 10 000 children. The single most important risk factor for pediatric VT is the presence of a central venous catheter. LÄS MER
