  2. 1. On Cooperative Surveillance, Online Trajectory Planning and Observer Based Control

    Author : David A. Anisi; Xiaoming Hu; Randal Beard; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surveillance Missions; Minimum-Time Surveillance; Unmanned Ground Vehicles; Connectivity Constraints; Combinatorial Optimization; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori; Applied mathematics; Tillämpad matematik;

    Abstract : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. READ MORE

  4. 2. Surveillance and follow-up of early prostate cancer

    Author : Mats Steinholtz Ahlberg; Anna Bill-Axelson; Lars Holmberg; Anna Lantz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; active surveillance; follow-up; biochemical recurrence; triggers for transition to radical treatment; overdiagnosis; overtreatment.; Urologi; Urology;

    Abstract : Active surveillance (AS) for prostate cancer was introduced to address overtreatment resulting from prostate-specific antigen (PSA) testing. Despite advancements such as Magnetic Resonance Imaging (MRI) and targeted biopsies, PSA remains crucial in prostate cancer diagnostics, leading to ongoing challenges of overdiagnosis and overtreatment.

  5. 3. Quality of life aspects of being diagnosed and living with prostate cancer

    Author : Oskar Bergengren; Anna Bill-Axelson; Ulrika Kreicbergs; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Oncology; Active surveillance; Quality of life; Survivorship; Satisfaction; Choice; Adherence; Life-style change; PSA;

    Abstract : Prostate cancer is largely a heterogenous disease, ranging from almost harmless to highly aggressive. Most men are diagnosed with favorable-risk disease with a long life expectancy even without treatment. The risk of overdiagnosing and overtreating these men is substantial, with reduced quality of life as a result. READ MORE

  6. 4. Prostate Cancer Screening - Aspects of Overdiagnosis

    Author : Rebecka Arnsrud Godtman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; active surveillance; age; cause of death; opportunistic; organized; overdiagnosis; prostate cancer; prostate-specific antigen; risk factors; screening; screening interval;

    Abstract : The overall aim of this thesis is to explore aspects of overdiagnosis, i.e. the diagnosis of a tumor that in the absence of screening would never have been diagnosed, in prostate cancer (PC) screening. READ MORE

  7. 5. How to model temporal changes in epidemiological data : Treatment trajectories in men with prostate cancer

    Author : Eugenio Ventimiglia; Pär Stattin; Paul C. Lambert; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; state transition model; life expectancy; active surveillance; watchful waiting;

    Abstract : Owing to the improvements in detection, diagnostics, and treatment, many men currently diagnosed with prostate cancer (PCa) have a low risk of PCa death. For many men PCa has become a chronic disease with a small risk of progression that remains even decades after date of diag-nosis. READ MORE
