  1. 1. Metabolic risk markers and relative survival in patients with aortic stenosis requiring surgery

    University dissertation from Umeå : Umeå universitet

    Author : Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic stenosis; aortic valve surgery; coronary artery disease; prospective cohort study; risk markers; lipoprotein a ; apolipoproteins; proteomics; troponin T; C-reactive protein; relative survival; observed survival; kardiologi; Cardiology;

    Abstract : Background: Aortic stenosis (AS) is the most common valve disorder requiring surgery in developed countries. The etiology of AS is only partly known.  Identification of new biomarkers in prospective studies could lead to novel insights in the etiology of AS, and possibly lead to improved clinical management.

  2. 2. Live and Let Die Critical regulation of survival in normal and malignant hematopoietic stem and progenitor cells

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Haematology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Hematologi;

    Abstract : The hematopoietic stem cell (HSC) is characterized by its ability to self-renew and produce all mature blood cells throughout the life of an organism. This is tightly regulated to maintain a balance between survival, proliferation, and differentiation. READ MORE

  3. 3. Correlated random effects models for clustered survival data

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Frank Eriksson; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Survival analysis; frailty model; competing risks; random effects; case-cohort; routine register; semiparametric; competing risks; case-cohort; semiparametric; Survival analysis; random effects; routine register; frailty model;

    Abstract : Frailty models are frequently used to analyse clustered survival data in medical contexts. The frailties, or random effects, are used to model the association between individual survival times within clusters. READ MORE

  4. 4. Stroke epidemiology in Southern Sweden. Trends in incidence and survival across two decades with projections into the future

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Björn Hallström; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; hospitalization; Neurology; neuropsychology; neurophysiology; Neurologi; trends; survival; incidence; stroke; epidemiology;

    Abstract : Background: Stroke is a major cause of death and disability. Investigations of the epidemiological trends for stroke might result in better understanding of stroke pathogenesis and prevention. READ MORE

  5. 5. Stress susceptibility, beta-blocker use and cancer survival

    University dissertation from Örebro : Örebro University

    Author : Ruzan Udumyan; Katja Fall; Scott Montgomery; Fang Fang; Edoardo Botteri; [2020]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stress resilience; β-blockers; primary cancer; survival analysis; overall mortality; cancer-specific mortality; register-based cohort study;

    Abstract : Accumulating evidence suggests that chronic stress may influence tumour biology through activation of neuroendocrine pathways and thus impair survival. However, measuring stressful exposures and their influence on health is challenging, partly due to substantial inter-individual variation in stress susceptibility. READ MORE
