  2. 16. Clinical probability assessment and biochemical markers in the diagnosis of deep vein thrombosis

    Author : Johan Elf; Malmö Klinisk koagulationsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Venous thrombosis; APC-PCI complex.; D-Dimer; Clinical probability; Diagnosis;

    Abstract : The combination of pre-test clinical probability assessment and D-dimer test is now widely applied in the diagnostic process of DVT. The general objective of the present investigation was to validate these results in a Swedish routine emergency setting were the prevalence of the disease is high and were the clinical probability assessment was handled by many junior physicians.

  4. 17. Prevention of Chlamydia trachomatis infections

    Author : Jens Boman; Elisabet Nylander; Urban Janlert; Hans Fredlund; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chlamydia trachomatis; cell culture; infertility; contact tracing; motivational interviewing; prevention;

    Abstract : Urogenital chlamydia infection, caused by the bacterium Chlamydia trachomatis (CT), is the most common sexually transmitted bacterial infection in Sweden. In 2008 it was estimated by WHO that there were 105.7 million new cases of CT worldwide, an increase by 4.2 million cases (4. READ MORE

  5. 18. Artificial neural networks classify myocardial perfusion images

    Author : Dan Lindahl; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; radionuclide imaging; ischemic heart disease; computer-assisted diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In the studies of this thesis, a method for automated classification of myocardial perfusion images was successfully developed and evaluated. The results show that the method, based on artificial neural networks, was equally good, or even better than human experts. READ MORE

  6. 19. Novel microfluidic based sample preparation methods for rapid separation and detection of viable bacteria from blood for sepsis diagnostics

    Author : Sharath Narayana Iyengar; Aman Russom; Jonas Tegenfeldt; KTH; []
    Keywords : microfluidics; Bioteknologi; Biotechnology;

    Abstract : Sepsis is a serious medical condition characterized by a whole-body inflammatory response caused by bloodstream infection. The final stage of sepsis can lead to septic shock, multiple organ failure, and death. In early sepsis, the concentration of bacteria in the bloodstream is typically low, making diagnosis challenging. READ MORE

  7. 20. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT

    Author : Marcus Söderberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; SPECT; PET; dosimetry; image quality; optimisation; dose reduction; automatic exposure control; contrast medium; phantom; image reconstruction; human observer;

    Abstract : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
