  1. 6. Bariatric Surgery : Outcomes after Gastric Bypass and Duodenal Switch

    Författare :Martin Löfling Skogar; Magnus Sundbom; Ville Wallenius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; fat-free mass; resting metabolic rate; bariatric surgery; obesity; Roux-en-Y Gastric Bypass; Duodenal Switch; air-displacement plethysmography; Bod Pod; indirect calorimetry assessment; BAROS; quality of life; weight loss; diabetes; hypertension; dyslipidmia; depression; pain; antidepressants; opioids; complications; healthcare consumption; adverse events; Surgery; Kirurgi;

    Sammanfattning : Obesity is associated with increased morbidity and mortality. A BMI >40 kg/m2 shortens life expectancy by about 10 years. The obesity related comorbidities diabetes, hypertension, dyslipidemia and sleep apnea contributes to the increased risk of cardiovascular events. There is also an increased risk of some forms of cancer (e. LÄS MER

  3. 7. Perioperative nutrition and insulin resistance

    Författare :Monika Svanfeldt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Insulin sensitivity; insulin resistance; hyperinsulinaemic normoglycaemic clamps; wholebody glucose kinetics; whole-body protein kinetics; indirect calorimetry; surgery; carbohydrate loading; hypocaloric nutrition; bed rest and TPN;

    Sammanfattning : Surgical trauma induces a catabolic response with development of insulin resistance as a central and well-characterised feature. In insulin resistance, the stimulating effect of insulin on peripheral glucose uptake and the suppressing effect of insulin on endogenous glucose release are decreased, resulting in hyperglycaemia.

  4. 8. Energy expenditure and substrate utilization during critical illness

    Författare :Martin Sundström Rehal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Critical illness leads to major alterations in metabolism. The net result is a state where catabolism predominates over anabolism. The associated loss of lean body mass is significant and potentially harmful. It is commonly held that providing calories and protein from nutrition may attenuate this response. LÄS MER

  5. 9. The new old normal : reassessing perioperative oxygen consumption and haemodynamics in the elderly

    Författare :Julia Jakobsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Perioperative haemodynamic instability and disturbances of global oxygen transport are associated with complications and organ injury after surgery. The continuously growing population of elderly in surgical care are at higher risk due to age-related cardiovascular alterations and increased prevalence of comorbidities. LÄS MER

  7. 10. Effects of prolactin on metabolism - changes induced by hyperprolactinemia

    Författare :Louise Nilsson; Göteborgs universitet; []
    Nyckelord :prolactin; prolactin receptor; hyperprolactinemia; adipose tissue; lipoprotein lipase; malonyl-CoA; glucose transporter 4; retinol-binding protein 4; adiponectin; lipid oxidation;

    Sammanfattning : High prolactin levels during breast-feeding, is recognized to influence metabolism in order to supply glucose and fat for milk production. Pathologic overproduction of prolactin, hyperprolactinemia, is a condition primarily associated with reproductive disorders; however, the metabolic impact of elevated prolactin indicates that these parameters might be considered in clinical management of the condition.
