  • Long-term survival and loss in expectancy of life in a population-based cohort of 7114 patients with diffuse large B-cell lymphoma
  • 2018
  • Ingår i: American Journal of Hematology. - : John Wiley and Sons Inc.. - 0361-8609 .- 1096-8652. ; 93:8, s. 1020-1028

    • Survival has improved among patients with diffuse large B-cell lymphoma (DLBCL) with the addition of anti-CD20 antibody therapy. We aimed to quantify trends and remaining loss in expectation of life (LEL) due to DLBCL at a national population-based level. Patients diagnosed with DLBCL 2000-2013 (N=7114) were identified through the Swedish Lymphoma Registry and classified according to the age-adjusted International Prognostic Index (aaIPI). The novel measure LEL is the difference between remaining life years among patients and the general population and was predicted using flexible parametric models from diagnosis and among 2-year survivors, by age and sex. Median age at DLBCL-diagnosis was 70 (18-105) years and 54.8% presented with stage III-IV disease. On average, LEL due to DLBCL decreased from 8.0 (95% CI: 7.7-8.3) to 4.6 (95% CI: 4.5-4.6) years over the study period. By risk group, LEL was most reduced among patients with aaIPI >= 2 aged 50-60 years. However, these patients were still estimated to lose >8 years in 2013 (eg, LELmales50years 8.6 years (95% CI: 5.0-12.3)). Among 2-year survivors, LEL was reduced from 6.1 years (95% CI: 5.6-6.5) (aaIPI >= 2) and 3.8 years (95% CI: 3.6-4.1) (aaIPI<2) to 1.1 (95% CI: 1.1-1.2) and 1.0 year (95% CI: 0.8-1.1), respectively. The reduction was observed across all ages. Results for females were similar. By using LEL we illustrate the improvement of DLBCL survival over time. Despite adequate immunochemotherapy, substantial LEL among patients with IPI >= 2 points to remaining unmet medical needs. We speculate that observed reduced losses among 2-year survivors indicate a reduction of late relapses.

  • The Norway spruce genome sequence and conifer genome evolution
  • 2013
  • Ingår i: Nature. - : Nature Publishing Group. - 0028-0836 .- 1476-4687. ; 497:7451, s. 579-584

    • Conifers have dominated forests for more than 200 million years and are of huge ecological and economic importance. Here we present the draft assembly of the 20-gigabase genome of Norway spruce (Picea abies), the first available for any gymnosperm. The number of well-supported genes (28,354) is similar to the >100 times smaller genome of Arabidopsis thaliana, and there is no evidence of a recent whole-genome duplication in the gymnosperm lineage. Instead, the large genome size seems to result from the slow and steady accumulation of a diverse set of long-terminal repeat transposable elements, possibly owing to the lack of an efficient elimination mechanism. Comparative sequencing of Pinus sylvestris, Abies sibirica, Juniperus communis, Taxus baccata and Gnetum gnemon reveals that the transposable element diversity is shared among extant conifers. Expression of 24-nucleotide small RNAs, previously implicated in transposable element silencing, is tissue-specific and much lower than in other plants. We further identify numerous long (>10,000 base pairs) introns, gene-like fragments, uncharacterized long non-coding RNAs and short RNAs. This opens up new genomic avenues for conifer forestry and breeding.

  • Location and spatial clustering of artists
  • 2014
  • Ingår i: Regional Science and Urban Economics. - 0166-0462 .- 1879-2308. ; 47:1, s. 128-137

    • Surveys of artists' location choices show that they disproportionately reside in large cities. This paper introduces a model that attempts to explain this urban preference. The model includes four factors: access to other artists; access to consumer demand; access to service jobs; and housing affordability. These four factors are combined in a spatial equilibrium model. An equilibrium spatial distribution of artists is derived from the model and is correlated with the actual distribution among Swedish municipalities. Subsequently, the model is used for an econometric estimation of factor effects. The results show that access to other artists and local access to service jobs are important localization factors. Educated labor used as a proxy for consumer demand has a significant effect on artists' location choices.

  • The geography of science in 12 European countries : a NUTS2-level analysis
  • 2020
  • Ingår i: Scientometrics. - : Springer. - 0138-9130 .- 1588-2861. ; 124:2, s. 1099-1125

    • Europe has a long history as a global center of scientific research, but not all European regions are alike. Regions such as Île de France and the corridor that stretches from Cambridge to Oxford via London produce a disproportionate share of Europe’s science output. An econometric analysis sheds light on the factors that explain the spatial distribution of European science. One result is that the regional volume of Web of Science publications depends on the regional number of researchers in higher education institutions. This is however not the only cause of high output. Universities and their surrounding regions are slowly evolving institutional structures. Some regions host universities that are more than 500 years old. A second key result is that an increase in the age of a region’s oldest university is associated with greater output, other things being equal. Third, interregional accessibility via road, rail, and air networks is important for small regions, but not for large ones. Conversely, regional high-tech R&D employment is important for large but not for small regions.

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Cognitive behavior therapy (CBT) is widely regarded as an effective treatment for obsessive compulsive disorder (OCD), but access to CBT therapists is limited. Internet-based CBT (ICBT) with therapist support is a way to increase access to CBT but has not been developed or tested for OCD. The aim of this study was to evaluate ICBT for OCD. less thanbrgreater than less thanbrgreater thanMethod: An open trial where patients (N = 23) received a 15-week ICBT program with therapist support consisting of psychoeducation, cognitive restructuring and exposure with response prevention. The primary outcome was the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), which was assessed by a psychiatrist before and immediately after treatment. Secondary outcomes were self-rated measures of OCD symptoms, depressive symptoms, general functioning, anxiety and quality of life. All assessments were made at baseline and post-treatment. less thanbrgreater than less thanbrgreater thanResults: All participants completed the primary outcome measure at all assessment points. There were reductions in OCD symptoms with a large within-group effect size (Cohens d = 1.56). At post-treatment, 61% of participants had a clinically significant improvement and 43% no longer fulfilled the diagnostic criteria of OCD. The treatment also resulted in statistically significant improvements in self-rated OCD symptoms, general functioning and depression. less thanbrgreater than less thanbrgreater thanConclusions: ICBT with therapist support reduces OCD symptoms, depressive symptoms and improves general functioning. Randomized trials are needed to confirm the effectiveness of this new treatment format.

  • Colloidal rare earth elements in a boreal river: Changing sources and distributions during the spring flood
  • 2006
  • Ingår i: Geochimica Et Cosmochimica Acta. - 0016-7037 .- 1872-9533. ; 70:13, s. 3261-3274
  • Tidskriftsartikel (refereegranskat)abstract
    • Variations in the physico-chemical speciation of the rare earth elements (REE) have been investigated in a subarctic boreal river during an intense spring flood event using prefiltered (< 100 mu m) samples, cross-flow (ultra)filtration (CFF), flow field-flow fractionation (FIFFF), and diffusive gradients in thin films (DGT). This combination of techniques has provided new information regarding the release and transport of the REE in river water. The colloidal material can be described in terms of two fractions dominated by carbon and iron, respectively. These two fractions, termed colloidal carrier phases, showed significant temporal changes in concentration and size distribution. Before the spring flood, colloidal carbon concentrations were low, the colloids being dominated by relatively large iron colloids. Colloidal concentrations increased sharply during the spring flood, with smaller carbon colloids dominating. Following the spring flood, colloidal concentrations decreased again, smaller carbon colloids still dominating. The REE are transported mainly in the particulate and colloidal phases. Before the spring flood, the REE composition of all measured fractions was similar to local till. During the spring flood, the REE concentrations in the colloidal and particulate fractions increased. The increase was most marked for the lighter REE, which therefore showed a strong enrichment when normalized to local till. Following the spring flood, the REE concentrations decreased again and reverted to a distribution similar to local till. These changes in the concentration and distributions of carbon iron and REE are interpreted in terms of changing hydrological flow paths in soil and bedrock which occur during the spring flood.

  • Short-term Resource Utilization and Cost-Effectiveness of Comprehensive Geriatric Assessment in Acute Hospital Care for Severely Frail Elderly Patients
  • 2018
  • Ingår i: Journal of the American Medical Directors Association. - : Elsevier. - 1525-8610 .- 1538-9375. ; 19:10, s. 871-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The objective of this study was to estimate the 3-month within-trial cost-effectiveness of comprehensive geriatric assessment (CGA) in acute medical care for frail elderly patients compared to usual medical care, by estimating health-related quality of life and costs from a societal perspective. Design: Clinical, prospective, controlled, 1-center intervention trial with 2 parallel groups. Intervention: Structured, systematic interdisciplinary CGA-based care in an acute elderly care unit. If the patient fulfilled the inclusion criteria, and there was a bed available at the CGA unit, the patient was included in the intervention group. If no bed was available at the CGA unit, the patient was included in the control group and admitted to a conventional acute medical care unit. Setting and Participants: A large county hospital in western Sweden. The trial included 408 frail elderly patients, 75 years or older, in need of acute in-hospital treatment. The patients were allocated to the intervention group (n = 206) or control group (n = 202). Mean age of the patients was 85.7 years, and 56% were female. Measures: The primary outcome was the adjusted incremental cost-effectiveness ratio associated with the intervention compared to the control at the 3-month follow-up. Results: We undertook cost-effectiveness analysis, adjusted by regression analyses, including hospital, primary, and municipal care costs and effects. The difference in the mean adjusted quality-adjusted life years gained between groups at 3 months was 0.0252 [95% confidence interval (CI): 0.0082-0.0422]. The incremental cost, that is, the difference between the groups, was -3226 US dollars (95% CI: -6167 to -285). Conclusion: The results indicate that the care in a CGA unit for acutely ill frail elderly patients is likely to be cost-effective compared to conventional care after 3 months.

  • Feasibility of a nurse-monitored outpatient-care programme for elderly patients with moderate-to-severe, chronic heart failure
  • 1998
  • Ingår i: European Heart Journal. - London, United Kingdom : W. B. Saunders Co. Ltd.. - 0195-668X .- 1522-9645. ; 19:8, s. 1254-60
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: To evaluate the feasibility of a nurse-monitored, outpatient-care program for elderly patients previously hospitalized with chronic heart failure. METHODS AND RESULTS: Patients with chronic heart failure hospitalized in the medical wards were screened to find those eligible for a randomized study to compare the effect of a nurse-monitored, outpatient-care programme aiming at symptom management, with conventional care. The inclusion criteria were patients classified in New York Heart Association classes III-IV, age 65 years, and eligibility for an outpatient follow-up programme. The total in-hospital population of patients discharged with a heart-failure diagnosis was surveyed. Eighty-nine per cent of all the hospitalized patients (n=1541) were 65 years old. Of these, 69% (n=1058) were treated in the medical wards which were screened. The study criteria were met by 158 patients (15%). No visits to the nurse occurred in 23 cases among the 79 patients randomized to the structured-care group (29%), mainly on account of death or fatigue. The numbers of hospitalizations and hospital days did not differ between the structured-care and the usual-care groups. CONCLUSIONS: Given the selection criteria and the outline of the interventions, the outpatient, nurse-monitored, symptom-management programme was not feasible for the majority of these elderly patients with moderate-to-severe, chronic heart failure, mainly because of the small proportion of eligible patients and the high drop-out rate. Management of these patients would have to be more adjusted to their home situation.
