  1. 1. Cardiac surgery and the kidney - studies on the effects of pharmacological interventions on renal perfusion, filtration and oxygenation

    Författare :Gudrun Bragadottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute; glomerular filtration rate; renal circulation; oxygen consumption; cardiac surgery; vasopressin; mannitol; levosimendan; estimating equations;

    Sammanfattning : Acute kidney injury (AKI) commonly complicates cardiac surgery and is associated with high mortality. Renal ischemia is considered to be the major cause. There is a close association between glomerular filtration rate (GFR), tubular sodium reabsorption and renal oxygen consumption (RVO2) in humans. LÄS MER

  3. 2. Sympathetic function in cardiac disorders.Upon cardio-renal sympathetic activity and effects of nitroglycerin in human heart failure

    Författare :Magnus Petersson; Göteborgs universitet; []
    Nyckelord :heart failure; renovascular hypertension; sympathetic nervous system; noradrenaline; mortality; renal circulation; cardiovascular physiology; baroreflex; nitroglycerin;

    Sammanfattning : This study explores pathophysiological mechanisms and prognostic implications of sympathetic activation in patients with atherosclerotic renovascular hypertension (RVH) and with chronic heart failure (CHF). Hitherto, it is unknown whether cardiac sympathetic activation is present in patients with RVH, the presence of which could relate to the increased cardiovascular mortality observed in this disorder.

  4. 3. Factors inhibiting ingestive behavior in chronic renal failure

    Författare :Abdel-Hafiz Mamoun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :rat; uremia; cholecystokinin octapeptide; nitric oxide; leptin; glucose; amino acids; anorexia; ingestive behavior; peritoneal dialysis solutions; hemodialysis;

    Sammanfattning : Protein-energy malnutrition and wasting occur in many patients with chronic renal failure. Reduced nutrient intake because of anorexia, nausea and vomiting, caused by uremic toxicity is an important factor. LÄS MER

  5. 4. Studies of EHEC and the complement system in renal diseases

    Författare :Zivile Békassy; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EHEC; hemolytic uremic syndrome; thrombotic microangiopathy; atypical hemolytic uremic syndrome; alternative pathway of complement; dense deposit disease; eculizumab;

    Sammanfattning : This thesis addressed the diagnosis, pathogenesis and clinical course of specific renal diseases hemolytic uremic syndrome (HUS) and dense deposit disease (DDD). HUS may be associated with infection caused by Enterohemorrhagic Escherichia coli (EHEC) or with complement dysfunction due to complement mutations or auto-antibodies (atypical HUS, aHUS). LÄS MER

  7. 5. Heparin-binding protein and organ failure in critical illness

    Författare :Jonas Tydén; Joakim Johansson; Magnus Hultin; Jakob Walldén; Sören Berg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparin-binding protein; Critical care; Shock; Acute respiratory distress syndrome; Acute kidney injury; Ventilator induced lung injury; Renal clearance; Anaesthesiology; anestesiologi;

    Sammanfattning : Background: For patients severely ill enough to require care in an intensive care unit (ICU), both the disease itself (e.g. bacteria in the blood in sepsis or fractures after trauma) and effects of the immune system can cause circulatory, pulmonary, or renal dysfunction. Leukocytes play a dominant role in the immune system. LÄS MER
