    • Objective. The incidence of prostate cancer is rising rapidly in Sweden and there is a need to better understand the pattern of diagnosis, tumor characteristics and treatment. Material and methods. Between 1996 and 2005, all new cases of adenocarcinoma of the prostate gland were intended to be registered in the National Prostate Cancer Register (NPCR). This register contains information on diagnosing unit, date of diagnosis, cause of diagnosis, tumor grade, tumor stage according to the TNM classification in force, serum prostate-specific antigen (PSA) levels at diagnosis and primary treatment given within the first 6 months after diagnosis. Results. In total, 72 028 patients were registered, comprising >97% of all pertinent incident cases of prostate cancer in the Swedish Cancer Register (SCR). During the study period there was a considerable decrease in median age at the time of diagnosis, a stage migration towards smaller tumors, a decrease in median serum PSA values at diagnosis, a decrease in the age-standardized incidence rate of men diagnosed with distant metastases or with a PSA level of >100 ng/ml at diagnosis and an increase in the proportion of tumors with Gleason score ≤6. Relatively large geographical differences in the median age at diagnosis and the age-standardized incidence of cases with category T1c tumors were observed. Treatment with curative intent increased dramatically and treatment patterns varied according to geographical region. In men with localized tumors and a PSA level of <20 ng/ml at diagnosis, expectant treatment was more commonly used in those aged ≥75 years than in those aged <75 years. Also, the pattern of endocrine treatment varied in different parts of Sweden. Conclusions. All changes in the register seen over time are consistent with increased diagnostic activity, especially PSA testing, resulting in an increased number of cases with early disease, predominantly tumors in category T1c. The patterns of diagnosis and treatment of prostate cancer vary considerably in different parts of Sweden. The NPCR continues to be an important source for research, epidemiological surveillance of the incidence, diagnosis and treatment of prostate cancer

    • DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

  • Spatial distribution of low-energy plasma around comet 67P/CG from Rosetta measurements
  • 2015
  • Ingår i: Geophysical Research Letters. - 0094-8276 .- 1944-8007. ; 42:11, s. 4263-4269
  • Tidskriftsartikel (refereegranskat)abstract
    • We use measurements from the Rosetta plasma consortium Langmuir probe and mutual impedance probe to study the spatial distribution of low-energy plasma in the near-nucleus coma of comet 67P/Churyumov-Gerasimenko. The spatial distribution is highly structured with the highest density in the summer hemisphere and above the region connecting the two main lobes of the comet, i.e., the neck region. There is a clear correlation with the neutral density and the plasma to neutral density ratio is found to be approximate to 1-210(-6), at a cometocentric distance of 10km and at 3.1AU from the Sun. A clear 6.2h modulation of the plasma is seen as the neck is exposed twice per rotation. The electron density of the collisionless plasma within 260km from the nucleus falls off with radial distance as approximate to 1/r. The spatial structure indicates that local ionization of neutral gas is the dominant source of low-energy plasma around the comet.

  • The National Prostate Cancer Register in Sweden 1998-2002 : trends in incidence, treatment and survival
  • 2005
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - 0036-5599 .- 1651-2065. ; 39:2, s. 117-123
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To provide a descriptive review of the establishment of the National Prostate Cancer Register (NPCR) in Sweden, to present clinical characteristics at diagnosis and to calculate the relative survival of different risk groups after 5 years. MATERIAL AND METHODS: Since 1998, data on all newly diagnosed prostate cancers, including TNM classification, grade of malignancy, prostate-specific antigen (PSA) level and treatment, have been prospectively collected. For the 35,223 patients diagnosed between 1998 and 2002, relative survival in different risk groups has been calculated. RESULTS: Between 1998 and 2002, 96% of all prostate cancer cases diagnosed in Sweden were registered in the NPCR. The number of new cases increased from 6137 in 1998 to 7385 in 2002. The age-standardized rate rose in those aged < 70 years, while it was stable, or possibly declining from 1999, in the older age groups. The proportion of T1c tumours increased from 14% to 28% of all recorded cases. The age-adjusted incidence of advanced tumours (M1 or PSA > 100 ng/ml) decreased by 17%. The proportion of patients receiving curative treatment doubled. Patients with N1 or M1 disease or poorly differentiated tumours (G3 or Gleason score 8-10) had a markedly reduced relative 5-year survival rate. CONCLUSIONS: It is possible to establish a nationwide prostate cancer register including basic data for assessment of the disease in the whole of Sweden. The introduction of PSA screening has increased the detection of early prostate cancer in younger men and, to a lesser extent, decreased the incidence of advanced disease. The effect of these changes on mortality is obscure but the NPCR in Sweden will serve as an important tool in such evaluation.

  • The Influence of Age and Sex on Genetic Associations with Adult Body Size and Shape: A Large-Scale Genome-Wide Interaction Study.
  • 2015
  • Ingår i: PLoS Genetics. - : Public Library of Science (PLoS). - 1553-7404 .- 1553-7390. ; 11:10
  • Tidskriftsartikel (refereegranskat)abstract
    • Genome-wide association studies (GWAS) have identified more than 100 genetic variants contributing to BMI, a measure of body size, or waist-to-hip ratio (adjusted for BMI, WHRadjBMI), a measure of body shape. Body size and shape change as people grow older and these changes differ substantially between men and women. To systematically screen for age- and/or sex-specific effects of genetic variants on BMI and WHRadjBMI, we performed meta-analyses of 114 studies (up to 320,485 individuals of European descent) with genome-wide chip and/or Metabochip data by the Genetic Investigation of Anthropometric Traits (GIANT) Consortium. Each study tested the association of up to ~2.8M SNPs with BMI and WHRadjBMI in four strata (men ≤50y, men >50y, women ≤50y, women >50y) and summary statistics were combined in stratum-specific meta-analyses. We then screened for variants that showed age-specific effects (G x AGE), sex-specific effects (G x SEX) or age-specific effects that differed between men and women (G x AGE x SEX). For BMI, we identified 15 loci (11 previously established for main effects, four novel) that showed significant (FDR<5%) age-specific effects, of which 11 had larger effects in younger (<50y) than in older adults (≥50y). No sex-dependent effects were identified for BMI. For WHRadjBMI, we identified 44 loci (27 previously established for main effects, 17 novel) with sex-specific effects, of which 28 showed larger effects in women than in men, five showed larger effects in men than in women, and 11 showed opposite effects between sexes. No age-dependent effects were identified for WHRadjBMI. This is the first genome-wide interaction meta-analysis to report convincing evidence of age-dependent genetic effects on BMI. In addition, we confirm the sex-specificity of genetic effects on WHRadjBMI. These results may provide further insights into the biology that underlies weight change with age or the sexually dimorphism of body shape.

  • Autologous haematopoietic stem cell transplantation for aggressive multiple sclerosis : the Swedish experience
  • 2014
  • Ingår i: Journal of Neurology, Neurosurgery and Psychiatry. - London, United Kingdom : BMJ Publishing Group. - 0022-3050 .- 1468-330X. ; 85:10, s. 1116-1121
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Autologous haematopoietic stem cell transplantation (HSCT) is a viable option for treatment of aggressive multiple sclerosis (MS). No randomised controlled trial has been performed, and thus, experiences from systematic and sustained follow-up of treated patients constitute important information about safety and efficacy. In this observational study, we describe the characteristics and outcome of the Swedish patients treated with HSCT for MS. METHODS: Neurologists from the major hospitals in Sweden filled out a follow-up form with prospectively collected data. Fifty-two patients were identified in total; 48 were included in the study and evaluated for safety and side effects; 41 patients had at least 1 year of follow-up and were further analysed for clinical and radiological outcome. In this cohort, 34 patients (83%) had relapsing-remitting MS, and mean follow-up time was 47 months. RESULTS: At 5 years, relapse-free survival was 87%; MRI event-free survival 85%; expanded disability status scale (EDSS) score progression-free survival 77%; and disease-free survival (no relapses, no new MRI lesions and no EDSS progression) 68%. Presence of gadolinium-enhancing lesions prior to HSCT was associated with a favourable outcome (disease-free survival 79% vs 46%, p=0.028). There was no mortality. The most common long-term side effects were herpes zoster reactivation (15%) and thyroid disease (8.4%). CONCLUSIONS: HSCT is a very effective treatment of inflammatory active MS and can be performed with a high degree of safety at experienced centres.

  • Nationwide population-based study on 30-day mortality after radical prostatectomy in Sweden
  • 2009
  • Ingår i: Scandinavian Journal of Urology and Nephrology. - London : Taylor & Francis. - 0036-5599 .- 1651-2065. ; 43:5, s. 350-356
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The incidence of prostate cancer in Sweden is increasing rapidly, as is treatment with curative intent. Radical prostatectomy (RP) is currently commonly performed, either within or outside large high-volume centres. The aim of this study was to assess the 30-day mortality rate after RP in Sweden. MATERIAL AND METHODS: In this nationwide population-based study, all men diagnosed with localized prostate cancer (< or =70 years, clinical stadium T1-2, prostate-specific antigen < 20 ng/ml) who underwent RP in Sweden between 1997 and 2002 were identified through the National Prostate Cancer Register (NPCR). Mortality within 30 days of RP was analysed through linkage between the follow-up study of the NPCR and the Regional Population Registers. The cause of death in the death certificates were compared with data from the hospitals concerned. To validate the results, a record linkage between the Inpatient Register and the National Population Register was also performed. RESULTS: The number of RPs performed increased over time. Among 3700 RPs performed, four deaths occurred during the first 30 days, yielding a 0.11% 30-day mortality rate. These deaths occurred at three different types of hospital and were all probably related to the RP. CONCLUSION: This study provides further evidence that RP is a procedure with very low perioperative mortality even when performed outside high-volume centres.

  • Potassium, chlorine, and sulfur in ash, particles, deposits, and corrosion during wood combustion in a circulating fluidized-bed boiler
  • 2007
  • Ingår i: Energy & Fuels. - 1520-5029 .- 0887-0624. ; 21:1, s. 71-81
  • Tidskriftsartikel (refereegranskat)abstract
    • The effect of the addition of chlorine and/or sulfur to the fuel on fly ash composition, deposit formation, and superheater corrosion has been studied during biomass combustion in a circulating fluidized-bed boiler. The chlorine (HCl (aq)) and sulfur (SO2 (g)) were added in proportions of relevance for the potassium chemistry. The composition of the bottom and the fly ashes was analyzed. Gas and particle measurements were performed downstream of the cyclone before the convection pass and the flue gas composition was recorded in the stack with a series of standard instruments and an FTIR analyzer. At the position downstream of the cyclone, a deposit probe was situated, simulating a superheater tube. Deposits on the probe and initial corrosion were examined. It is concluded that addition of sulfur and chlorine increases the formation of submicron particles leading to deposition of potassium sulfate and chloride. The results compare well with earlier work based on laboratory-scale experiments concerning effects of chlorine and sulfur on potassium chemistry.
