    • Objectives: To determine the health-related quality of life (HRQOL) and its relationship to disease variables, vertebral fractures, and employment status in female patients with systemic lupus erythematosus (SLE). Methods: HRQOL was assessed with the Swedish version of the Medical Outcomes Study (MOS) 36-Item Short Form Survey (SF-36) in female patients (n=163) and in age- and sex-matched controls (n=1045). Associations between the SF-36 score and demographics, disease variables, prevalent vertebral fractures, and employment status were analysed. Results: The SLE patients, aged 20 to 82 years, scored significantly lower than the controls on all SF-36 subscales. Patients with vertebral fractures were older, had greater disease damage, and lower physical functioning (PF) than patients without fractures. Of the SLE patients of working age (n=142), 54% worked full or part time. These patients scored their HRQOL significantly higher (better) than patients not working. Being able to work was significantly associated with low age and high scores in PF and role physical (RP): the area under the receiver operating characteristic (ROC) curve for these variables was 0.82, confidence interval 0.75-0.89. Conclusions: HRQOL is substantially lower in SLE than in the general population but working ability indicates better health. We encourage further research regarding the effects on HRQOL by preventive actions taken against work disability in SLE.

    • ABSTRACT: INTRODUCTION: Our objective was to determine the frequency of and factors associated with prevalent vertebral compression fractures in female SLE patients attending rheumatologists in Western Sweden. METHODS: In this cross sectional study 150 women were included. They were examined with x-ray of thoracic and lumbar spine (Th4-L4). A reduction of at least 20% of any vertebral height, assessed by Genant's semiquantitative method, was defined as a fracture. Bone mineral density (BMD) was measured by dual energy x-ray absorptiometry (DXA). RESULTS: Median patient age was 47 years (20-82) and disease duration 11 years (1-41). Only 6 (4%) women had a history of clinical compressions whereas 43 (29%) had at least one radiological fracture each. The patients with at least one fracture at any site were characterized by higher age (p<0.001), being postmenopausal (p<0.01), higher Systemic Lupus International Collaborative Clinics Damage Index (p<0.05), lower BMD total hip and femoral neck (p<0.05), more peripheral fractures (p< 0.01), medication with bisphosphonates (p<0.05) and calcium and vitamin D3 (p<0.05). There were no significant differences regarding current or cumulative glucocorticosteroid dose between the groups. In logistic regression analyses high age remained as risk factor of at least one vertebral fracture at any site whereas low BMD in total hip was associated with vertebral fracture in lumbar spine. CONCLUSION: Radiological compression fractures are common but seldom diagnosed in SLE patients. High age and low BMD in total hip, but not in spine, was associated with vertebral fractures.

    • Anders Lundberg was one of the founding editorial board members for EBR when it began its life in 1976 under the editorship of John Eccles. He was also one of the most prolific contributors to the journal with a total of 49 papers, including a series of 16 on the topic of "integration in descending motor pathways controlling the forelimb in the cat". He continued as an editor of the journal until volume 16 when he persuaded his younger colleague Hans Hultborn to take his place. Hans is one of the authors of the obituary. –John Rothwell

  • Complete regioselective addition of grignard reagents to pyrazine N-oxides, toward an efficient enantioselective synthesis of substituted piperazines.
  • 2010
  • Ingår i: Organic letters. - : American Chemical Society (ACS). - 1523-7052 .- 1523-7060. ; 12:2, s. 284-6
  • Tidskriftsartikel (refereegranskat)abstract
    • A conceptually new one-pot strategy for the synthesis of protected substituted piperazines via the addition of Grignard reagents to pyrazine N-oxides is presented. This strategy is high yielding (33-91% over three steps), step-efficient, and fast. The synthesized N,N-diprotected piperazines are convenient to handle and allow for orthogonal deprotection at either nitrogen for selective transformations. In addition, this is a synthetic route to enantiomerically enriched piperazines by using a combination of phenyl magnesium chloride and (-)-sparteine, which resulted in enantiomeric excesses up to 83%.

  • The clinical expression of asthma in schoolchildren has changed between 1996 and 2006.
  • 2010
  • Ingår i: Pediatric allergy and immunology : official publication of the European Society of Pediatric Allergy and Immunology. - : Wiley. - 1399-3038 .- 0905-6157. ; 21:5, s. 859-66

    • Several studies have reported diverging trends in the prevalence of asthma and wheeze. The aim of this study was to investigate the clinical expression of childhood asthma in 1996 and 2006 by studying asthma morbidity, treatment, and environmental exposures in school children with physician-diagnosed asthma and wheeze, respectively. All children enrolled in first or second grade (7-8 yr-old) in three municipalities in northern Sweden were invited to a questionnaire study in 1996 and 2006, respectively. In 1996, 3430 (97%) participated; and in 2006, 2585 (96%) participated. The same parental completed questionnaire, including the ISAAC questions, was used in both surveys. Physician-diagnosed asthma was reported at 5.7% in 1996 and 7.4% in 2006. A significantly greater proportion of children with asthma were using inhaled corticosteroids (ICS) in 2006, 67% vs. 55% in 1996. This increase was parallel to a major decrease in severe asthma symptoms such as disturbed sleep because of wheeze (49% vs. 38%) and troublesome asthma (21% vs. 11%). The prevalence of current wheeze among the asthmatics decreased significantly; however, this was seen only among children not using ICS. Parental smoking decreased significantly as did the proportion living in damp buildings. In conclusion, although asthma remains a major public health issue in school age children, children with asthma had less respiratory symptoms and a better asthma control in 2006 compared to 1996. This parallels with an increase in treatment with ICS, more beneficial environmental conditions, and an increased diagnostic intensity resulting in a larger proportion of children with mild symptoms being diagnosed as having asthma.

  • Veblen’s theory of the leisure class revisited : Implications for optimal income taxation
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Almost all previous studies on public policy under relative consumption concerns have ignored the role of leisure for status comparisons. Inspired by Veblen (1899), this paper considers a two-type optimal income tax model, where people care about their relative consumption, and where the importance of relative consumption increases with the use of leisure due to increased consumption visibility. We show that increased consumption positionality typically implies higher marginal income tax rates for both ability-types. Using a leisure-weighted measure of reference consumption, rather than a measure where leisure plays no role as in the previous literature, increases the marginal income tax rate implemented for the low-ability type and decreases the marginal income tax rate implemented for the high-ability type, i.e., it gives rise to a regressive tax component.

  • Bilateral Prophylactic Mastectomy in Swedish Women at High Risk of Breast Cancer: A National Survey.
  • 2011
  • Ingår i: Annals of surgery. - : Lippincott Williams and Wilkins; 1999. - 1528-1140 .- 0003-4932. ; 253:6, s. 1147-1154
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.
