1. Managing depression via the Internet : self-report measures, treatment & relapse prevention
Sammanfattning : Cognitive behaviour therapy (CBT) is an effective treatment for depression but access is limited. One way of increasing access is to offer CBT via the Internet. In Study I, guided Internet-based CBT was found to have a large effect on depressive symptoms compared to taking part in an online discussion group. LÄS MER
2. Treatment failure in pediatric acute myeloid leukemia: factors associated with frequency and outcome of resistant disease and relapse
Sammanfattning : Although the prognosis for childhood acute myeloid leukemia (AML) has improved over the last decades to a survival of over 70%, still 30-40 % relapse and 5-10% experience resistant disease with poor prognosis. The aim of this thesis was to perform a detailed analysis of disease characteristics and treatment in children with relapsed and resistant AML to provide means to improve prognosis. LÄS MER
3. Prognostic factors of electroconvulsive therapy for depression
Sammanfattning : Depression is a severe disorder that can be difficult to treat. One approach to treating depression is electroconvulsive therapy (ECT), whereby electricity is administered through electrodes fastened to the patient’s head. This procedure is effective, however not all patients respond. LÄS MER
4. Genetic and epigenetic characterization of pediatric high hyperdiploid acute lymphoblastic leukemia
Sammanfattning : The aim of this thesis was to analyze the genetic and epigenetic characteristics of pediatric high hyperdiploid acute lymphoblastic leukemia (HeH ALL), the most common type of childhood malignancy. The three original articles presented in this thesis have addressed three major questions regarding HeH ALL: what are the genetic characteristics of the most common structural abnormality – dup(1q)? Are aberrant methylation patterns involved in leukemogenesis? How do diagnostic and relapse samples relate to each other genetically? In article I we found that the proximal breakpoints of dup(1q)-positive Burkitt lymphomas (BL) and pediatric HeH ALLs cluster close to the centromere, suggesting this region to be breakprone, and that five genes on 1q were significantly overexpressed and thus potentially pathogenetically important.

5. DNA methylation as a prognostic marker i acute lymphoblastic leukemia
Sammanfattning : Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Most ALL cases originate from immature B-cells (BCP-ALL) and are characterized by reoccurring structural genetic aberrations. These aberrations hold information of the pathogenesis of ALL and are used for risk stratification in treatment. LÄS MER
