  • Adherence to adjuvant endocrine therapy after breast cancer in Sweden 2008-2010 : a nationwide survey
  • 2019
  • Konferensbidrag (övrigt vetenskapligt)abstract
    • Background: In estrogen receptor (ER) positive early breast cancer (EBC) adjuvant endocrine therapy (AET) is crucial to reduce recurrence and mortality. Previous studies have shown that adherence to AET is lower than expected and could negatively affect outcome. Since the year of 2000, BC patients in Sweden are treated in accordance to national guidelines. Treatment is offered at a low cost for the patient. The aim of the study was to estimate the adherence to AET in Sweden by regions and age groups. Methods: Women with a first primary EBC diagnosis 2008-2010 were identified through the Swedish Cancer Registry (SCR). Individual tumour and treatment data were retrieved from the Swedish National Breast Cancer Registry (SNBCR). Patients with ER negative tumours, small tumours (≤ 10 mm) and metastatic disease was excluded from the study since there were no indication to AET. Likewise, were individuals with AET registered to be administered by a third part excluded. Dispensed treatment from pharmacies was obtained through the Swedish Prescription Registry and medication possession rate (MPR) was calculated as number of dispensed doses divided by treatment duration in days. Good adherence to treatment in a patient was set at MPR ≥ 80 %. Adherence was calculated for 3 and 5 years. Results: Twenty-one thousand sixteen (21 016) individuals with a first primary BC between 2008 and 2010 was identified through SCR of which 20 596 were registered in the SNBCR. A total of 10 176 met the inclusion criteria in the study. Adherence after 3 years was 88.0 % and after 5 years 82.5 %. Adherence differed between regions in Sweden and was positively associated with age at diagnosis between 41-74 years. Urban areas had a lower adherence than rural areas (80.7 % vs 83.6 %; p= <0.001). Conclusions: Adherence to AET in Sweden was good, although there were differences by age and urban and rural areas. Further studies are needed to identify factors affecting differences in adherence, with the purpose of initiate actions to increase adherence to AET in ER positive EBC patients.

  • Common breast cancer susceptibility alleles are associated with tumor subtypes in BRCA1 and BRCA2 mutation carriers: results from the Consortium of Investigators of Modifiers of BRCA1/2.
  • 2011
  • Ingår i: Breast cancer research : BCR. - 1465-542X. ; 13:6
  • Tidskriftsartikel (refereegranskat)abstract
    • ABSTRACT: INTRODUCTION: Previous studies have demonstrated that common breast cancer susceptibility alleles are differentially associated with breast cancer risk for BRCA1 and/or BRCA2 mutation carriers. It is currently unknown how these alleles are associated with different breast cancer subtypes in BRCA1 and BRCA2 mutation carriers defined by estrogen (ER) or progesterone receptor (PR) status of the tumor. METHODS: We used genotype data on up to 11,421 BRCA1 and 7,080 BRCA2 carriers, of whom 4,310 had been affected with breast cancer and had information on either ER or PR status of the tumor, to assess the associations of twelve loci with breast cancer tumor characteristics. Associations were evaluated using a retrospective cohort approach. RESULTS: The results suggested stronger associations with ER-positive breast cancer than ER-negative for eleven loci in both BRCA1 and BRCA2 carriers. Among BRCA1 carriers, SNP rs2981582 (FGFR2) exhibited the biggest difference based on ER status (per-allele HR for ER-positive=1.35, 95%CI:1.17-1.56 vs HR=0.91, 95%CI:0.85-0.98 for ER-negative, P-heterogeneity=6.5e-6). In contrast, SNP rs2046210 at 6q25.1 near ESR1 was primarily associated with ER-negative breast cancer risk for both BRCA1 and BRCA2 carriers. In BRCA2 carriers, SNPs in FGFR2, TOX3, LSP1, SLC4A7/NEK10, 5p12, 2q35, and1p11.2 were significantly associated with ER-positive but not ER-negative disease. Similar results were observed when differentiating breast cancer cases by PR status. CONCLUSIONS: The associations of the twelve SNPs with risk for BRCA1 and BRCA2 carriers differ by ER-positive or ER-negative breast cancer status. The apparent differences in SNP associations between BRCA1 and BRCA2 carriers, and non-carriers, may be explicable by differences in the prevalence of tumor subtypes. As more risk modifying variants are identified, incorporating these associations into breast cancer subtype-specific risk models may improve clinical management for mutation carriers.

  • Sveriges arter och naturtyper i EU:s art- och habitatdirektiv : Resultat från rapportering 2019 till EU av bevarandestatus 2013-2018
  • 2020
  • Rapport (övrigt vetenskapligt)abstract
    • Sverige har en variationsrik natur med storslagen fjällmiljö, myllrande våtmarker, vattendrag och sjöar, kust och hav, skogar och odlingslandskap, alla med ett rikt växt och djurliv. Den här fantastiska biologiska mångfalden tas ofta för given och ibland som en lyx, men oavsett vilket är det en förutsättning för vår överlevnad.2019 rapporterade Sverige statusen till EU för perioden 2013–2018 för de naturtyper och arter i Sverige som är listade i art- och habitatdirektivet. Den berättar att 20 procent av naturtyperna och 40 procent av arterna mår bra. Den biologiska mångfalden är hårt trängd i såväl Sverige som i andra EU-länder.Den här rapporten sammanfattar Sveriges rapportering och innehåller beskrivningar av status för naturtyper och arter, påverkan, hot och trender. Rapporten ger kunskap om tillståndet för den biologiska mångfalden i Sverige med hjälp av de arter och naturtyper som är listade i EU:s art- och habitatdirektiv.Rapporten visar hur naturmiljöerna i Sverige förändas, och sammanfattar den senaste kunskapen om vilka faktorer som driver dessa förändringar. Även exempel på hur vi genom restaurerings- och skötselåtgärder kan hejda förlusten av biologisk mångfald tas upp.

  • Collaborative learning as common sense: structure, roles and participation amongst doctoral students and teachers in music education : beyond communities of practice
  • 2017
  • Ingår i: Visions of Research in Music Education. - 1938-2065. ; 29
  • Tidskriftsartikel (refereegranskat)abstract
    • The article communicates an investigation of how collaborative learning is constituted in a PhD-course, namely Collaborative learning in music educational settings. The course was organized and run in a way that aimed to investigate, develop and encourage collaborative learning among students and teachers in the third circle. Material produced and analysed included log-books, assignments, peer-response, after-thoughts, and a Facebook discussion-thread. The results are presented as descriptions of the constituent parts of collaborative learning occurring in the “rooms” of the course. The results show the importance of structure as well as awareness when it comes to roles and kinds of participation.

  • Cooperative inhibitory effects of budesonide and formoterol on eosinophil superoxide production stimulated by bronchial epithelial cell conditioned medium
  • 2007
  • Ingår i: International Archives of Allergy and Immunology. - : Karger. - 1423-0097. ; 143:3, s. 201-210
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Improved asthma control by combinations of inhaled glucocorticosteroids (GCs) and long-acting beta(2)-agonists (LABAs) includes a reduced frequency and severity of exacerbations. In view of the association of exacerbations with increased airway inflammation, the question has arisen as to whether LABAs are able to complement the known anti- inflammatory activity of GCs. To address this, we studied the effects of a LABA, formoterol (FORM), and a GC, budesonide (BUD), alone and in combination, on bronchial epithelial cell-mediated eosinophil superoxide production in vitro. Methods: We employed 2 experimental approaches. First, superoxide production by human eosinophils incubated with conditioned medium (CM) from human bronchial epithelial cells cultured for 24 h with vehicle, BUD, FORM or BUD + FORM was measured (Epi/Eos assay). Second, eosinophils were stimulated with vehicle-CM to which the drugs were added (Eos assay). Superoxide production was determined as the superoxide dismutase-inhibitable reduction of ferricytochrome C. Results: CM increased eosinophil superoxide generation (p < 0.01) and epithelial-derived granulocyte macrophage colony-stimulating factor was the mediator responsible. In both assays, FORM dose-dependently inhibited eosinophil superoxide similarly and in the same concentration range as BUD. The BUD + FORM combination was more effective than BUD alone, and it completely inhibited CM-induced superoxide production in the Epi/Eos assay, suggesting complementary effects of both drugs on bronchial epithelial cells and eosinophils. Conclusions: The cooperative, inhibitory effects of BUD and FORM on eosinophils and bronchial epithelial cells, in terms of their effects on eosinophil superoxide production, may represent a possible mechanism for the enhanced anti-inflammatory efficacy of BUD and FORM combination therapy of asthma.

  • A hypothesis-generating search for new genetic breast cancer syndromes : a national study in 803 Swedish families
  • 2007
  • Ingår i: Hereditary Cancer in Clinical Practice. - 1731-2302. ; 5:1, s. 17-24
  • Tidskriftsartikel (refereegranskat)abstract
    • Among Swedish families with an inherited predisposition for breast cancer, less than one third segregate mutations in genes known to be associated with an increased risk of breast cancer in combination with other types of tumours. In a search for new putative familial breast cancer syndromes we studied Swedish families undergoing genetic counselling during 1992-2000. Four thousand families from counselling clinics in Sweden were eligible for study. Families with breast cancer only were excluded, as were families with mutations in genes already known to be associated with malignant diseases. We identified 803 families with two or more cases of breast cancer and at least one other type of cancer. The observed proportion of different types of non-breast cancer was compared with the percentage distribution of non-breast cancer tumours in Sweden in 1958 and 1999. We found tumours in the colon, ovary, endometrium, pancreas and liver, as well as leukaemia in a significantly larger proportion of the study population than in the general population in both years. These tumours were also seen among families where several members had one additional tumour, suggesting that malignancies at these sites, in combination with breast tumours, could constitute genetic syndromes. Endometrial carcinoma has not previously been described in the context of breast cancer syndromes and the excess of malignancies at this site could not be explained by secondary tumours. Thus, we suggest that endometrial carcinoma and breast cancer constitute a new breast cancer syndrome. Further investigation is warranted to categorize phenotypes of both breast and endometrial tumours in this subgroup.
