    Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

  3. 2. Craniopharyngioma. Morbidity and Structural Changes in the Brain

    Författare :Sigríður Bára Fjalldal; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; craniopharyngioma; hypothalamus; hypothalamic obesity; metabolism; cognition; magnetic resonance imaging; diffusion tensor imaging; white matter lesions; morbidity; cardiovascular risk; craniofaryngiom; hypotalamus; hypotalamisk fetma; ämnesomsättning; kognition; magnetkameraundersökning; vitsubstansförändringar; dödlighet; hjärt-kärlsjukdomar;

    Sammanfattning : Hypothalamus (HT) is a brain structure which serves as a coordination center for several vital body functions. Craniopharyngioma (CP) is a pituitary tumor with high morbidity, primarily due to HT lesion. LÄS MER

  4. 3. Tillbaka till livet : att skapa säkerhet i hjärtintensivvården

    Författare :Sabrina Thelander; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; intensive care; safety; risk; ethnography; social interaction; medical technology; illness trajectory; hierarchies of power; medical practice; Hjärt- o kärlsjukdomar; Intensivvård; Omvårdnad; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This study analyses how medical personnel in cardiac intensive care create safety despite the uncertainties and dangers involved in this type of care. Using an ethnographic approach, involving participant observation and interviews, the author studies the means by which the staff, as a part of their everyday work, achieve safety - in their relationships to patients, medical technology and each other.

  5. 4. Diabetes Mellitus and Cardiovascular Risk : epidemiology, etiology and intervention

    Författare :Aslak Rautio; Kurt Boman; Anna Norhammar; Umeå universitet; []
    Nyckelord :Diabetes; Cardiovascular risk; epidemiology; myocardial infarction; stroke; fibrinolysis; insulin treatment; Diabetes; kardiovaskulär risk; epidemilogi; hjärtinfarkt; stroke; fibrinolys; insulinbehandling; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : Background: The Framingham Study from 1988 showed a heavy impact of diabetes mellitus (DM) on the risk and prognosis of cardiovascular disease (CVD). Several other studies have confirmed that DM is an independent risk factor for coronary heart disease (CHD) and that patients with DM have a poor prognosis. LÄS MER

    Sammanfattning : Patients with chronic kidney disease are at higher risk of developing cardiovascular disease. The complex, interaction between the kidney and the cardiovascular system is incompletely understood, particularly at the early stages of the cardiovascular continuum. LÄS MER
