  2. 16. Health economics and its measures in rheumatoid arthritis

    Author : Johan Karlsson; Reumatologi och molekylär skelettbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cost-utility analysis; Cost-of-illness; Quality of life; EuroQol 5-Dimensions; Antirheumatic agents; TNF inhibition; Outcome assessment; Disease activity; Disability; Health economics; Rheumatoid arthritis;

    Abstract : Objectives: To study: (I) the impact on cost-utility analyses of applying different national EuroQol 5-Dimensions (EQ-5D) preference sets; (II and III) whether, in methotrexate-refractory, early rheumatoid arthritis (RA), the addition of infliximab results in superior health-related quality of life (HRQoL) and may be considered cost-effective, as compared to adding sulfasalazine and hydroxychloroquine; (IV) how costs relate to disability (measured by the health-assessment questionnaire, HAQ), disease activity (28-joint disease activity score, DAS28) and HRQoL (EQ-5D) in RA. Methods: In the observational SSATG register, one-year quality-adjusted life-year (QALY) accumulation of two interventions was compared according to the UK, US, or Danish EQ-5D preference sets.

  4. 17. Spectral Inequalities and Their Applications in Quantum Mechanics

    Author : Fabian Portmann; Ari Laptev; Robert Seiringer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spectral inequalities; quantum mechanics; Hardy inequalities; Sobolev inequalities; Lieb-Thirring inequalities; stability of matter; Bose gases; Bose-Einstein condensation; Mathematics; Matematik; Fysik; Physics;

    Abstract : The work presented in this thesis revolves around spectral inequalities and their applications in quantum mechanics.In Paper A, the ground state energy of an atom confined to two dimensions is analyzed in the limit when the charge of the nucleus Z becomes very large. READ MORE

  5. 18. The Dark Side of the Universe

    Author : Martin Eriksson; Lars Bergström; Pierre Salati; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Physics; Fysik;

    Abstract : The dark side of the Universe presents astroparticle physics with its most outstanding challenge to date. As observational cosmology in recent years has reached a level of unprecedented accuracy, we have learned that there is very little in the Universe that we know much about, and very much about which we know very little.

  6. 19. Aspects of Dimensional Deconstruction and Neutrino Physics

    Author : Tomas Hällgren; Tommy Ohlsson; Stephan J. Hubber; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensional deconstruction; higher-dimensional gauge theories; discretized gravity; neutrino mass; neutrino mixing; neutrino oscillations; Engineering physics; Teknisk fysik;

    Abstract : The existence of at or curved extra spatial dimensions provides new insights into several of the problems which face the Standard Model of particle physics, including the gauge hierarchy problem, the smallness of neutrino masses, and the dark matter problem. However, higher-dimensional gauge theories are not renormalizable and can only be considered as low-energy effective theories, with limited applicability. READ MORE

  7. 20. Quality of life and ethics-patients with ischemic heart disease

    Author : Lars Westin; Medicinsk etik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Bioethics; Prognosis; Quality of life; Questionnaires; Cardiovascular system; Myocardial ischemia;

    Abstract : One month and one year after acute myocardial infarction (AMI) (n=296), coronary artery bypass grafting (CABG) (n=99) and percutaneous coronary intervention (PCI) (n=18) patients completed a questionnaire for self-assessment of quality of life (QoL) during the period 1989?1991. Patients differed from age- and sex-matched controls (n=88) in both somatic and emotional dimensions, but less after one year of follow-up. READ MORE
