  1. 1. Long-term outcome after cataract surgery : a longitudinal study

    Författare :Britta Lundqvist; Eva Mönestam; Ulf Stenevi; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract; cataract surgery outcome; longitudinal study; subjective visual acuity; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Sammanfattning : Background Cataract surgery is the most common surgical procedure carried out in the developed world and surgery volumes have increased considerably during the last decades. Various aspects of the surgical procedure, including surgical incision size and intraocular lens materials, have changed substantially, improving the safety and the quality of the outcome. LÄS MER

  2. 2. Musculoskeletal pain, memory, and aging : Cross-sectional and longitudinal findings

    Författare :Stefan Söderfjell; Bo Molander; Björn Lyxell; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Musculoskeletal pain; Cognitive functioning; Episodic memory; Semantic memory; Implicit memory; Cross-sectional; Longitudinal; Age; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The general aim of the thesis was to investigate potential differences in memory performance between participants across the adult life span with and without self-reported musculoskeletal pain. Chronic musculoskeletal pain is a major health related problem in our society. LÄS MER

  3. 3. Räkna med bokstäver! En longitudinell studie av vägar till en förbättrad algebraundervisning på gymnasienivå

    Sammanfattning : Huvudsyftet med studien är att skapa insikter om algebrakunskaper och villkor för algebralärande hos gymnasieelever. Ett andra syfte är att med utgångspunkt i resultaten föreslå vägar till en förbättrad algebraundervisning inom det svenska skolsystemet. LÄS MER

  4. 4. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

    Författare :Sara Pudas; Jonas Persson; Lars Nyberg; Emrah Düzel; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aging; episodic memory; individual differences; longitudinal assessment; magnetic resonance imaging; hippocampus; frontal cortex; psykologi; Psychology;

    Sammanfattning : Aging is typically associated with declining mental abilities, most prominent for some forms of memory. There are, however, large inter-individual differences within the older population. Some people experience rapid decline whereas others seem almost spared from any adverse effects of aging. LÄS MER

  5. 5. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

    Författare :Martin Fredholm; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

    Sammanfattning : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.
