- Genetic associations for the reoccurrence of venous thromboembolism (VTE) are not well described. Our aim was to investigate if common genetic variants, previously found to contribute to the prediction of first time thrombosis in women, were associated with risk of recurrence. The Thromboembolism Hormone Study (TEHS) is a Swedish nationwide case-control study (2002-2009). A cohort of 1,010 women with first time VTE was followed up until a recurrent event, death or November 2011. The genetic variants in F5 rs6025, F2 rs1799963, ABO rs514659, FGG rs2066865, F11 rs2289252, PROC rs1799810 and KNG1 rs710446 were assessed together with clinical variables. Recurrence rate was calculated as the number of events over the accumulated patient-time. Cumulative recurrence was calculated by Kaplan-Meier curve. Cox proportional-hazard model was used to estimate hazard ratios (HR) and 95 % confidence intervals (95 % CI) between groups. A total of 101 recurrent events occurred during a mean follow-up time of five years. The overall recurrence rate was 20 per 1,000 person-years (95 % CI; 16-24). The recurrence rate was highest in women with unprovoked first event and obesity. Carriers of the risk alleles of F5 rs6025 (HR=1.7 (95 % CI; 1.1-2.6)) and F11 rs2289252 (HR=1.8 (95 % CI; 1.1-3.0)) had significantly higher rates of recurrence compared to non-carriers. The cumulative recurrence was 2.5-fold larger in carriers of both F5 rs6025 and F11 rs2289252 than in non-carriers at five years follow-up. In conclusion, F5 rs6025 and F11 rs2289252 contributed to the risk of recurrent VTE and the combination is of potential clinical relevance for risk prediction.

- Objectives: This study aims to characterize the epidemiology of immunocompetent Primary central nervous system lymphoma (PCNSL) diagnosed 2000-2013 in Sweden.Methods: Cases were identified in the population-based Swedish Lymphoma Register. Incidence per 100000 person-years and 95% confidence intervals (CI) were calculated, and PCNSL-specific survival was estimated using relative survival. Tests for temporal trends were performed using Poisson regression. Population incidence of all brain tumors was retrieved for comparison.Results: With 359 identified PCNSL cases (median age 66years), overall incidence was 0.26 (95% CI: 0.24-0.29) and the average annual increase 4% (P=.002). The increasing trend was primarily observed among elderly individuals (70+years). Similarly, an increase in incidence of all brain tumors was noted only among the elderly. There was no significant improvement in relative survival across the study period although, among fit patients (with Eastern Cooperative Oncology Group, EGOC 0), survival plateaued 6years after diagnosis.Conclusion: The increasing PCNSL incidence in the elderly was consistent with an increasing incidence of brain tumors of any type and may in part be attributable to improved diagnostics and reporting in this group. New treatment options have not yet translated into general survival improvements in a population-based setting, although the presence of long-term survivors among fit patients is encouraging.

- Background: Magnetic resonance diffusion tensor imaging (MR-DTI) is used increasingly to detect diffuse axonal injury (DAI) after traumatic brain injury (TBI). Primary objective: The primary objective was to investigate the changes in the diffusion properties of the corpus callosum in the acute phase and 6 months after TBI and to examine the correlation between DTI parameters and clinical outcome. Research design: Longitudinal prospective study. Methods and procedures: MR-DTI was performed in eight patients with suspected DAI within 11 days and at 6 months post-injury. Six controls were also examined. Fractional anisotropy (FA), trace and parallel and perpendicular diffusivity of the corpus callosum were analysed. The main outcome was the extended Glasgow Outcome Scale score, assessed at 6 months. Main outcomes and results: A significant reduction in FA in the corpus callosum was seen in the acute phase in patients compared with the healthy controls. There was no significant change in the parallel or perpendicular eigenvalues or trace. At 6 months, a significant reduction in FA and a significant increase in trace and perpendicular eigenvalues were noticed compared with controls. Conclusions: The diffusion properties of the corpus callosum correlated with clinical outcome in this longitudinal investigation.

Cardiovascular disease and mortality after a first episode of venous thromboembolism in young and middle-aged women

Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with a history of venous thromboembolism (VTE) seem to have an increased risk of arterial cardiovascular disease (CVD). Objectives: To evaluate the risk of CVD and overall mortality after a first episode of VTE in women and to assess common risk factors for VTE and CVD. Patients/methods: We performed a cohort study inviting 1433 women with a previous VTE (exposed) and 1402 women without VTE (unexposed). The cohort was derived from TEHS, a Swedish population-based case-control study on risk factors for VTE in women age 18-64 years. The women were recruited in 2002-2009. During 2011 information on CVD and mortality was obtained from a questionnaire and from the Swedish Patient Register and the Cause of Death Register. Hazard ratios (HR) for CVD and their 95% confidence intervals (CI) were calculated using Cox regression. In multivariate analyses we adjusted for age, smoking, diabetes mellitus, hypertension and body mass index. Results: 2108 (75%) women (mean age 47 +/- 13 years) accepted participation. During the total follow up of 11,920 person years 35 (3.2%, 95% CI 0.7-2.1) among the exposed and 14 (1.4%, 95% CI 0.2-4.3) among the unexposed had any CVD event. The adjusted HR for CVD was 2.0 (95% CI 1.1-3.9) the adjusted HR for mortality was 2.3 (95% CI 1.2-4.6) Conclusion: Women with a previous VTE had a two-fold increased risk of CVD and overall mortality. Adjusting for cardiovascular risk factors only modestly changed the estimates.

Designing learning environments for heterogeneous groups in Second Life
- 2010

Konferensbidrag (refereegranskat)abstract
- The project that we will discuss in this paper aims to support the areas of teaching and learning in a multidisciplinary collaboration between the Centre for Languages and Literature (SOL), Faculty of Engineering (LTH) and Centre for Educational Development (CED), all Lund University, Sweden, by using the virtual world Second Life (SL) as a platform for collaborative learning activities. Students from China (Fudan University, Shanghai) and LTH students will meet, interact and collaborate in various activities and assignments. In this paper, we will primarily address the following question: In what way do we develop a learning environment and design the introductory part of a course in order to ensure that the students are well equipped for learning in Second Life - with particular consideration to dealing with a bi-cultural student group?
