  2. 1. Machine Learning Survival Models : Performance and Explainability

    Author : Abdallah Alabdallah; Mattias Ohlsson; Thorsteinn Rögnvaldsson; Sepideh Pashami; Erik Frisk; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Survival Analysis; Explainable Artificial Intelligence; Survival Patterns; Counterfactual Explanations; Evaluation Metrics; Concordance Index;

    Abstract : Survival analysis is an essential statistics and machine learning field in various critical applications like medical research and predictive maintenance. In these domains understanding models' predictions is paramount. READ MORE

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

    Author : Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; Umeå universitet; []
    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.

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

    Author : Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; Cell and molecular biology; Cell- och molekylärbiologi; Haematology; 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

  6. 4. Correlated random effects models for clustered survival data

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

    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

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

    Author : Björn Hallström; Lund Neurologi; []
    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
