1. 6. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers

   Författare :Ronnie Wirestam; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic radiology; cortical activation; diffusion; tumor; tumour; ischemic stroke; ischaemic stroke; tracer kinetics; bolus tracking; phase mapping; brain motion; intracranial dynamics; blood flow; haemodynamics; vascularity; MRS; perfusion; MRI; magnetic resonance; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Sammanfattning : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

3. 7. Epidemiology of heart failure and feasibility of home care in patients with worsening chronic heart failure

   Författare :Masoud Shafazand; Göteborgs universitet; []
   Nyckelord :Chronic heart failure; mortality; deterioration; hospitalisation; gender; home care; quality-adjusted life years; emergency care; health care costs; ischaemic; non-ischaemic; health-related quality of life; conventional care; acute myocardial infarction; coronary heart disease; heart failure;

   Sammanfattning : Aim: To investigate gender-specific trends in long-term mortality in patients hospitalised for ischaemic and non-ischaemic heart failure (HF) and explore temporal trends in the risk of HF complicating acute myocardial infarction (AMI). Another aim is to characterise patients with chronic heart failure (CHF) that seek an emergency department (ED) because of their deteriorating condition and evaluate the feasibility of home care (HC) in comparison with conventional care (CC) in patients with worsening CHF.

4. 8. Nuclear Magnetic Resonance for Diffusion Imaging Development and evaluation of spin-echo-based pulse sequences for in vivo studies of water self-diffusion

   Författare :Sara Brockstedt; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfusion fraction; electrocardiographic triggering; segmented EPI SEPI ; echo-planar imaging EPI ; fast spin-echo FSE ; spin-echo SE ; navigator echoes; phase corrections; diffusion; Magnetic resonance; MRI; ischaemic stroke; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. LÄS MER

5. 9. Metabolic disturbances in shift workers

   Författare :Berndt Karlsson; Giovanni Costa; Umeå universitet; []
   Nyckelord :shift work; epidemiology; mortality; diabetes; stroke; coronary heart disease; obesity; triglycerides; HDL-cholesterol; insulin; glucose; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : An increased risk for coronary heart disease among shift workers is earlier shown in the epidemiological literature. The aim of this thesis has been to penetrate metabolic disturbances and obesity among shift workers compared to day workers, and to compare if there are differences in total mortality or cause specific mortality of coronary heart disease (CHD), diabetes or ischaemic stroke in between the two groups.

7. 10. Facilitation of recovery after ischaemic stroke : early dexamphetamine and physiotherapy treatment

   Författare :Louise Martinsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Stroke; cerebral infarct; dexamphetamine; physiotherapy; recovery; safety; efficacy; pharmacokinetics; meta-analysis;

   Sammanfattning : Purpose: The overall aims of the thesis were to investigate the safety, efficacy, and pharmacokinetics of dexamphetamine (d-amph) after cerebral infarct, and the effects of different amounts of physiotherapy in combination with d-amph on recovery, early after cerebral infarct in patients with severe stroke. Patients and methods: The thesis is based on three studies on patients in the department of Neurology, Karolinska Hospital, Sweden, and on one meta-analysis based on data collected from previously published studies.
