Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Kapitlet behandlar läraryrkenas positioner och professionsstatus på utbildningens fält. Efter ett kort inledande avsnitt om fältet följer en översikt över svensk skolpolitik de senaste decennierna. Översikten fokuserar skolan och läraryrkenas samhälleliga inbäddning och förutsättningar efter skolverksamhetens kommunalisering och avreglering. Skolan som arbetsorganisation, rektorers framskjutna position som arbetsgivarrepresentanter och den ur professionaliseringssynpunkt strategiska betydelsen av lärarlegitimation och karriärtjänster diskuteras med utgångspunkt från Eliot Freidsons tre konkurrerande styrningslogiker – professionalismens, byråkratins och marknadens. Slutsatsen är att mixen av olika styrningslogiker förändrats på professionens bekostnad till förmån för byråkratins och marknadens. Kan lärarlegitimation och karriärtjänster fungera som lärarförbundens språngbräda i en för läraryrkenas professionalisering problematisk utbildningspolitisk kontext?

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Kapitlet behandlar det svenska utbildningsfältets professionalisering från kyrkligt förankrade kunskapsideal till skolundervisningens förvetenskapligande. Utbildningsfältet är avgränsat i förhållande till den högre utbildningens fält och omfattar utbildningar på grundskole- och gymnasienivå. I Bourdieus mening är fältet ett system av specialiserade institutioner och agenter (kyrka, stat, akademi, lärarförbund etc.) som utifrån olika intressen och positioner konkurrerar om erkännande och makt att definiera skolutbildningens syften och innehåll. Fältets framväxt och förändring följer olika faser från formering, konsolidering och konstituering till professionalisering. Den historiska exposén visar hur kampen mellan etablerade och konkurrerande kunskapsideal och utbildningspolitiska intressen utmynnade i att existerande strukturer utmanades och förändrades. Nya skolformer och lärarkategorier växte fram och etablerades. Den senaste fasen, fältets professionalisering, inleddes med välfärdsstatens strävan att modernisera och demokratisera skolundervisningen genom inrättandet av ett enhetligt skolsystem, en ny lärarprofession samt förvetenskapligande av lärarutbildningen och läraryrkets kunskapsbas.

- New strategies for prevention and treatment of type 2 diabetes (T2D) require improved insight into disease etiology. We analyzed 386,731 common single-nucleotide polymorphisms (SNPs) in 1464 patients with T2D and 1467 matched controls, each characterized for measures of glucose metabolism, lipids, obesity, and blood pressure. With collaborators (FUSION and WTCCC/UKT2D), we identified and confirmed three loci associated with T2D - in a noncoding region near CDKN2A and CDKN2B, in an intron of IGF2BP2, and an intron of CDKAL1 - and replicated associations near HHEX and in SLC30A8 found by a recent whole-genome association study. We identified and confirmed association of a SNP in an intron of glucokinase regulatory protein (GCKR) with serum triglycerides. The discovery of associated variants in unsuspected genes and outside coding regions illustrates the ability of genome-wide association studies to provide potentially important clues to the pathogenesis of common diseases.

Migrant Agricultural Workers and Their Socio-‐economic, Occupational and Health Conditions– A Literature Review
- 2013
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective This study provides the summary of current knowledge about migrant work in agriculture available from journal articles, books, reports and other relevant academic publications, focusing on political, economic, legal, social and medical aspects of migrant work in agriculture. Methods A systematic search was carried out on the LibHub and Google Scholar databases in order to compile the existing peer-reviewed publications, research reports, and policy papers concerning migrant work in agriculture. The literatures was selected through the following process: (1) reading the title and abstract in English for the period 1960 – 2011; (2) reading the entire text of selected articles; (3) making a manual search of the relevant quotations in the selected articles; (4) eliminating articles without a focus on migrant populations and the themes of central interest, and then reading and analyzing the definitive set of articles. Results In spite of their varying geographical focus, scope, unit of analysis and settings, most of the studies reviewed highlighted that migrant farmworkers work under very poor working conditions and face numerous health and safety hazards, including occupational chemical and ergonomic exposures, various injuries and illnesses and even death, discrimination and social exclusion, poor pay and long working hours, and language and cultural barriers. Many studies also reported poor enforcement of labour regulations and a lack of health and safety training on the farms, difficulty accessing medical care and compensation when injured or ill. Conclusions The studies have also pointed out the lack of research in relation to labour, health, psychosocial, and wage conditions of migrant farmworkers. The accumulated results of the study indicate that the issues and problems migrant farmworkers face are multidimensional, and there is a need for both policy development and further research in order to address migrant workers’ problems.

Ingår i: Atherosclerosis. - : Elsevier BV. ; 177, s. 287-290
-
Tidskriftsartikel (refereegranskat)abstract
- Identification of cell and tissue specific genes may provide novel insights to signaling systems and functions. Macrophages play a key role in many diseases including atherosclerosis. Using DNA microarrays we compared the expression of approximately 10,000 genes in 56 human tissues and identified 23 genes with predominant expression in macrophages. The identified genes include both genes known to be macrophage specific and genes previously not well described in this cell type. Tissue distribution of two genes, liver X receptor (LXR) alpha and interleukin-1 receptor antagonist (IL1RN), was verified by real-time RT-PCR. We conclude that comparison of expression profiles from a large number of tissues can be used to identify genes that are predominantly expressed in certain tissues. Identification of novel macrophage specific genes may increase our understanding of the role of this cell in different diseases.

Annealing behavior between room temperature and 2000 degrees C of deep level defects in electron-irradiated n-type 4H silicon carbide
- 2005
-
Ingår i: Journal of Applied Physics. - : AIP Publishing. - 0021-8979 .- 1089-7550. ; 98:4
-
Tidskriftsartikel (refereegranskat)abstract
- The annealing behavior of irradiation-induced defects in 4H-SiC epitaxial layers grown by chemical-vapor deposition has been systematically studied by means of deep level transient spectroscopy (DLTS). The nitrogen-doped epitaxial layers have been irradiated with 15-MeV electrons at room temperature and an isochronal annealing series from 100 to 2000 degrees C has been performed. The DLTS measurements, which have been carried out in the temperature range from 120 to 630 K after each annealing step, revealed the presence of six electron traps located in the energy range of 0.45-1.6 eV below the conduction-band edge (E-c). The most prominent and stable ones occur at E-c-0.70 eV (labeled Z(1/2)) and E-c-1.60 eV(EH6/7). After exhibiting a multistage annealing process over a wide temperature range, presumably caused by reactions with migrating defects, a significant fraction of both Z(1/2) and EH6/7 (25%) still persists at 2000 degrees C and activation energies for dissociation in excess of 8 and similar to 7.5 eV are estimated for Z(1/2) and EH6/7, respectively. On the basis of these results, the identity of Z(1/2) and EH6/7 is discussed and related to previous assignments in the literature.

Tidskriftsartikel (refereegranskat)abstract
- Aims and objectives. In this study we describe the development of a short, easy-to-use questionnaire to measure postoperative recovery and evaluate its content validity and intra-patient reliability. The questionnaire is designed to evaluate the progress of postoperative recovery and the long-term follow-up of possible effects of interventions during recovery.Method. The study involved four steps. 1) A conceptualisation and item definitions were based on a theoretical framework and a description of patients' postoperative recovery from the perspective of patients, registered nurses and surgeons. 2) Content validity of items was tested through expert judgements. 3) A test run of the questionnaire was performed to confirm its feasibility and workload requirement. 4) The stability of the questionnaire was evaluated through intra-patient reliability assessment.Results. As a result of the operationalisation process of the concept postoperative recovery, five dimensions (physical symptoms, physical functions, psychological, social, activity) and 19 items were identified. Each item was formulated as a statement in the questionnaire. Content validity was judged to be high. After the pre-test of the questionnaire a revision with refinements in the layout was made. The vast majority of items showed a high level of intra-patient reliability.Conclusion. Based on a theoretical framework and empirical data, we developed a short and easy-to-use tentative questionnaire to measure patient-reported postoperative recovery. Initial support for content validity was established. The vast majority of items showed a high level of test-retest reliability.

Tidskriftsartikel (refereegranskat)abstract
- Background. The previously developed Postoperative Recovery Profile (PRP) questionnaire is intended for self-assessment of general recovery after surgery. The aim of this study was to further evaluate the questionnaire regarding the construct validity and ability to discriminate recovery profiles between groups. Furthermore, the item variables of greatest importance during the progress of recovery were investigated.Methods. Postoperative recovery was assessed during the period from discharge to 12 months after lower abdominal- and orthopedic surgery. Construct validity was evaluated by comparing the assessments from the PRP-questionnaire and a global recovery scale. Recovery profiles of the diagnose groups were displayed by the cumulative proportion recovered participants over time. The importance of item variables was investigated by ranking ordering.Results. A total of 158 patients were included. The result showed that 7.6 % of all possible pairs were disordered when comparing the assessments from the PRP questionnaire and the global recovery scale. Twelve months after discharge 51 % participants in the abdominal group were fully recovered, as compared with the 73%, in the orthopedic group (95% CI: 6 % to 40 %). The item variable pain appeared as top five at eight measurement occasions of eight possible in both the abdominal and the orthopedic groups. The importance of the items was emphasized.Conclusions. The PRP questionnaire allows for evaluation of the progress of postoperative recovery, and can be useful to assess patient-reported recovery after surgical treatment. Knowledge about recovery profiles can assist clinicians in determining the critical time points for measuring change.

Twelve months after discharge the PRP assessments discriminated significantly the recovery profiles of the abdominal and orthopaedic groups. The variable pain was one of the top five most important issues at each follow-up occasion in both study groups. The importance of the item variables was thereby emphasized. Conclusions The PRP questionnaire allows for evaluation of the progress of post-operative recovery, and can be useful to assess patient-reported recovery after surgical treatment both on individual and group levels. Knowledge about recovery profiles can assist clinicians in determining the critical time points for measuring change.

Differential global gene expression response patterns of human endothelium exposed to shear stress and intraluminal pressure
- 2005
-
Ingår i: J Vasc Res. - : S. Karger AG. - 1018-1172. ; 42:5, s. 441-52
-
Tidskriftsartikel (refereegranskat)abstract
- We investigated the global gene expression response of endothelium exposed to shear stress and intraluminal pressure and tested the hypothesis that the two biomechanical forces induce a differential gene expression response pattern. Intact living human conduit vessels (umbilical veins) were exposed to normal or high intraluminal pressure, or to low or high shear stress in combination with a physiological level of the other force in a unique vascular ex vivo perfusion system. Gene expression profiling was performed by the Affymetrix microarray technology on endothelial cells isolated from stimulated vessels. Biomechanical forces were found to regulate a very large number of genes in the vascular endothelium. In this study, 1,825 genes were responsive to mechanical forces, which corresponds to 17% of the expressed genes. Among pressure-responsive genes, 647 genes were upregulated and 519 genes were down regulated, and of shear stress-responsive genes, 133 genes were upregulated and 771 down regulated. The fraction of genes that responded to both pressure and shear stimulation was surprisingly low, only 13% of the regulated genes. Our results indicate that the two different stimuli induce distinct gene expression response patterns, which can also be observed when studying functional groups. Considering the low number of overlapping genes, we suggest that the endothelial cells can distinguish between shear stress and pressure stimulation.

Gene profiling reveals increased expression of uteroglobin and other anti-inflammatory genes in glucocorticoid-treated nasal polyps.
- 2004
-
Ingår i: Journal of Allergy and Clinical Immunology. - : Elsevier BV. - 0091-6749 .- 1097-6825. ; 113:6, s. 1137-43
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Treatment with local glucocorticoids (GCs) decreases symptoms and the size of nasal polyps. This might depend on the downregulation of proinflammatory genes, as well as the upregulation of anti-inflammatory genes. OBJECTIVE: We sought to identify GC-regulated anti-inflammatory genes in nasal polyps. METHODS: Affymetrix DNA microarrays were used to analyze the expression of 22,283 genes in 4 nasal polyps before and after local treatment with fluticasone (400 microg/d). Expression of uteroglobin and mammaglobin B was analyzed with real-time PCR in 6 nasal polyps and in nasal biopsy specimens from 6 healthy control subjects. RESULTS: Two hundred three genes had changed in expression in treated polyps, and 139 had known functions: 54 genes were downregulated, and 85 were upregulated. Genes associated with inflammation constituted the largest single functional group. These genes affected key steps in inflammation (eg, immunoglobulin production; antigen processing and presentation; and the chemoattraction and activation of granulocytes, T cells, and B cells). Several proinflammatory genes were downregulated. In contrast, some anti-inflammatory genes were upregulated. The gene that increased most in terms of expression was uteroglobin. This was confirmed with real-time PCR. By contrast, expression of uteroglobin was lower in untreated polyps than in healthy nasal mucosa. Immunohistochemical investigation showed staining of uteroglobin in the epithelium and in seromucous glands in control subjects and in nasal polyps. CONCLUSION: Upregulation of anti-inflammatory genes, such as uteroglobin, might contribute to the effects of local treatment with GCs in nasal polyps.

No germline mutations in supposed tumour suppressor genes SAFB1 and SAFB2 in familial breast cancer with linkage to 19p.
- 2008
-
Ingår i: BMC Medical Genetics. - : BioMed Central. - 1471-2350. ; 9
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The scaffold attachment factor B1 and B2 genes, SAFB1/SAFB2 (both located on chromosome 19p13.3) have recently been suggested as tumour suppressor genes involved in breast cancer development. The assumption was based on functional properties of the two genes and loss of heterozygosity of intragenic markers in breast tumours further strengthened the postulated hypothesis. In addition, linkage studies in Swedish breast cancer families also indicate the presence of a susceptibility gene for breast cancer at the 19p locus. Somatic mutations in SAFB1/SAFB2 have been detected in breast tumours, but to our knowledge no studies on germline mutations have been reported. In this study we investigated the possible involvement of SAFB1/SAFB2 on familiar breast cancer by inherited mutations in either of the two genes.RESULTS: Mutation analysis in families showing linkage to the SAFB1/2 locus was performed by DNA sequencing. The complete coding sequence of the two genes SAFB1 and SAFB2 was analyzed in germline DNA from 31 affected women. No missense or frameshift mutations were detected. One polymorphism was found in SAFB1 and eight polymorphisms were detected in SAFB2. MLPA-anlysis showed that both alleles of the two genes were preserved which excludes gene inactivation by large deletions.CONCLUSION: SAFB1 and SAFB2 are not likely to be causative of the hereditary breast cancer syndrome in west Swedish breast cancer families.

More cost-effective management of patients with musculoskeletal disorders in primary care after direct triaging to physiotherapists for initial assessment compared to initial general practitioner assessment.
- 2019
-
Ingår i: BMC musculoskeletal disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 20:1
-
Tidskriftsartikel (refereegranskat)abstract
- A model for triaging patients in primary care to provide immediate contact with the most appropriate profession to treat the condition in question has been developed and implemented in parts of Sweden. Direct triaging of patients with musculoskeletal disorders (MSD) to physiotherapists at primary healthcare centres has been proposed as an alternative to initial assessment by general practitioners (GPs) and has been shown to have many positive effects. The aim of this study was to evaluate the cost-effectiveness from the societal perspective of this new care-pathway through primary care regarding triaging patients with MSD to initial assessment by physiotherapists compared to standard practice with initial GP assessment.Nurse-assessed patients with MSD (N=55) were randomised to initial assessment and treatment with either physiotherapists or GPs and were followed for 1year regarding health-related quality of life, utilization of healthcare resources and absence from work for MSD. Quality-adjusted life-years (QALYs) were calculated based on EQ5D measured at 5 time-points. Costs for healthcare resources and production loss were compiled. Incremental cost-effectiveness ratios (ICERS) were calculated. Multiple imputation was used to compensate for missing values and bootstrapping to handle uncertainty. A cost-effectiveness plane and a cost-effectiveness acceptability curve were construed to describe the results.The group who were allocated to initial assessment by physiotherapists had slightly larger gains in QALYs at lower total costs. At a willingness-to-pay threshold of 20,000 €, the likelihood that the intervention was cost-effective from a societal perspective including production loss due to MSD was 85% increasing to 93% at higher thresholds. When only healthcare costs were considered, triaging to physiotherapists was still less costly in relation to health improvements than standard praxis.From the societal perspective, this small study indicated that triaging directly to physiotherapists in primary care has a high likelihood of being cost-effective. However, further larger randomised trials will be necessary to corroborate these findings.ClinicalTrials.gov NCT02218749 . Registered August 18, 2014.

- The Nordic Centre of Excellence CRAICC (Cryosphere-Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011-2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research and innovation regarding climate change issues in the Nordic region. CRAICC gathered more than 100 scientists from all Nordic countries in a virtual centre with the objectives of identifying and quantifying the major processes controlling Arctic warming and related feedback mechanisms, outlining strategies to mitigate Arctic warming, and developing Nordic Earth system modelling with a focus on short-lived climate forcers (SLCFs), including natural and anthropogenic aerosols. The outcome of CRAICC is reflected in more than 150 peer-reviewed scientific publications, most of which are in the CRAICC special issue of the journal Atmospheric Chemistry and Physics. This paper presents an overview of the main scientific topics investigated in the centre and provides the reader with a state-of-the-art comprehensive summary of what has been achieved in CRAICC with links to the particular publications for further detail. Faced with a vast amount of scientific discovery, we do not claim to completely summarize the results from CRAICC within this paper, but rather concentrate here on the main results which are related to feedback loops in climate change-cryosphere interactions that affect Arctic amplification.

Eemian interglacial reconstructed from a Greenland folded ice core

Tidskriftsartikel (refereegranskat)abstract
- Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to the warmer-than-present climate of the Eemian has thus remained unclear. Here we present the new North Greenland Eemian Ice Drilling ('NEEM') ice core and show only a modest ice-sheet response to the strong warming in the early Eemian. We reconstructed the Eemian record from folded ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records. On the basis of water stable isotopes, NEEM surface temperatures after the onset of the Eemian (126,000 years ago) peaked at 8 +/- 4 degrees Celsius above the mean of the past millennium, followed by a gradual cooling that was probably driven by the decreasing summer insolation. Between 128,000 and 122,000 years ago, the thickness of the northwest Greenland ice sheet decreased by 400 +/- 250 metres, reaching surface elevations 122,000 years ago of 130 +/- 300 metres lower than the present. Extensive surface melt occurred at the NEEM site during the Eemian, a phenomenon witnessed when melt layers formed again at NEEM during the exceptional heat of July 2012. With additional warming, surface melt might become more common in the future.

Biokuma - Biokulturellt arv och alternativ matproduktion : Slutrapport, oktober 2020-september 2022
- 2023
-
Rapport (populärvet., debatt m.m.)abstract
- Den här rapporten sammanfattar Interregprojektet Biokulturellt arv och alternativ matproduktion (Biokuma). Projektet, som löpt från oktober 2020 till och med september 2022, är en del av Interregs Sverige-Norge-program. EU-programmet ger stöd till svensk-norska projektsamarbeten som utvecklar samhället inom olika insatsområden. I enlighet med prosjektets syfte har Biokuma bidragit til kunnskapsoppbygging som visar att alternative driftsformer i landbruket ivaretar og viderefører ett biokulturellt arv. Därmed bidrar den alternativa matproduktionen till omställningen till ett hållbart samhälle. De alternativa matproducenterna är dock främst intresserade av de gröna delarna av det biokulturella arvet. En förstärkning av kulturarvsperspektivet skulle med andra ord vara önskvärd för en effektivare reproduktion och förvaltning av det biokulturella arvet. Även när det gäller kunskapsöverföring, både i form av formella utbildningar och praktik, betonas ofta de gröna delarna av det biokulturella arvet. En annan problematik, påvisad i projektet Biokuma, är att de alternativa matproducenterna möter en rad utmaningar i sin verksamhet, och flera av dessa utmaningar utgör hot mot uthålligheten inom denna verksamhetsform. Något som i sin tur utgör ett hot mot den reproduktion av det biokulturella arvet som de alternativa matproducenterna står för. Det är arbetsintensivt att bedriva småskaligt jordbruk i samklang med naturen. Arbetet ger samhälleliga natur- och kulturmiljövinster som gårdsbrukaren oftast inte får betalt för. Försäljningsarbetet är också ofta tidskrävande och sker på en mängd olika sätt, till exempel genom Rekoring och torghandel, återkommande marknader eller matevent, gårdsbutiker, äggbodar, prenumeration, självplock, e-handel, detaljhandel, eget eller andras café eller restaurang. Även genom försäljning till förädlingsföretag och mathantverkare eller till storhushåll. Gårdarna kan även få inkomster från sitt gårdsbruk på andra sätt, exempelvis genom uthyrning av djur för slyröjning och markberedning, liksom naturvårdsarbete med kor i våtmarker och getter vid sätrar. I syfte att stödja uthållighet, utveckling och konkurrenskraft hos den alternativa matproduktionen och en robust och växande reproduktion av det biokulturella arvet har projektet tagit fram en rad rekommendationer. Rekommendationerna riktar sig till matproducenter, myndigheter och andra intressenter. Projektets resultat och rekommendationer sprids genom olika kommunikationskanaler i form av exempelvis vetenskapliga artiklar, en handbok, populärvetenskapliga texter, blogginlägg, filmer och inspelade presentationer, samt ett gediget erfarenhetsutbyte mellan matproducenter, myndigheter och annat branschfolk. Genom ett varierat kommunikationsarbete har resultaten från projektet spridits till en bred målgrupp i både Sverige och Norge, medan de vetenskapliga publikationerna når forskare även internationellt. I denna rapport presenterar vi projektets bakgrund och målsättning, organisation, de aktiviteter som genomförts, samt resultat och effekter av arbetet. Det gränsöverskrid-ande arbetet har haft en central roll i projektet. Då förhållandena för reproduktion av biokulturellt arv och alternativ matproduktion till viss del skiljer sig mellan Norge och Sverige har erfarenhetsutbytet mellan såväl forskare som alternativa matproducenter på både sidor av gränsen varit betydelsefullt för projektets resultat. I rapporten redogör vi för projektets gränsöverskridande mervärden samt arbetet med de horisontella kriterierna hållbar utveckling, jämställdhet mellan kvinnor och män och lika möjligheter och icke-diskriminering. Vi redovisar också viktiga nyckeltal i form av antal gemensamma natur- och kulturarv där insatser för ökad tillgänglighet och hållbart bevarande har genomförts inom ramen för projektet. På projektets hemsida, sola.kau.se/biokuma, hittar du samtliga publikationer och filmer som projektet resulterat i. Sidan uppdateras kontinuerligt efter projektslut allteftersom fler publikationer tillkommer.

Characterization of deep level defects in 4H and 6H SiC via DLTS, SIMS and MeV e-beam irradiation
- 1996

Konferensbidrag (refereegranskat)abstract
- Electrically active defects in both 4H and 6H polytypes of SiC have been observed through the use of deep level transient spectroscopy (DLTS). Schottky contacts were grown by VPE with doping concentrations, the epitaxial layer having a doping concentration in the range of 10 exp 14/cu cm to 10 exp 17/cu cm. Numerous levels have been found in the as-grown n-type 6H-SiC samples, and SIMS and MeV electron irradiation have been employed to correlate the defect levels to impurities or structural defects. In contrast, only a single level is observed in the as-grown 4H-SiC samples.

Electrically active point defects in n-type 4H–SiC

- An electrically active defect has been observed at a level position of ∼ 0.70 eV below the conduction band edge (Ec) with an extrapolated capture cross section of ∼ 5×10−14 cm2 in epitaxial layers of 4H–SiC grown by vapor phase epitaxy with a concentration of approximately 1×1013 cm−3. Secondary ion mass spectrometry revealed no evidence of the transition metals Ti, V, and Cr. Furthermore, after electron irradiation with 2 MeV electrons, the 0.70 eV level is not observed to increase in concentration although three new levels are observed at approximately 0.32, 0.62, and 0.68 eV below Ec with extrapolated capture cross sections of 4×10−14, 4×10−14, and 5×10−15 cm2, respectively. However, the defects causing these levels are unstable and decay after a period of time at room temperature, resulting in the formation of the 0.70 eV level. Our results suggest strongly that the 0.70 eV level originates from a defect of intrinsic nature. The unstable behavior of the electron irradiation-induced defects at room temperature has not been observed in the 6H–SiC polytype.

- HpaA is a Helicobacter pylori-specific lipoprotein that has been shown to be an effective protective antigen for mucosal vaccination against H. pylori infection in mice. However, detergents are needed for the purification of full-length HpaA (HpaA(full)), which might confer toxicity, thus making HpaA(full) unsuitable for use in a human vaccine. We here describe a recombinantly produced truncated version of HpaA (HpaA(trunc)), which is easily purified without the use of detergents. Evaluation in the murine H. pylori infection model showed that sublingual immunization with HpaA(trunc) was equally immunogenic and protective as immunization with HpaA(full). Immunization with a combination of HpaA(trunc) and recombinant UreB protein induced strong immune responses to both antigens and importantly had a strong synergistic effect on protection, associated with synergistically increased expression of IL-17 in the stomach. Notably, sublingual immunization with HpaA(trunc) and UreB was superior to corresponding intragastric immunization with regard to the level of protection induced. In conclusion, HpaA(trunc) is a promising, readily produced, non-toxic recombinant antigen for inclusion in a mucosal vaccine against H. pylori infection, which may preferably be given sublingually together with UreB.

Tidskriftsartikel (refereegranskat)abstract
- Background: Nursing documentation is essential for facilitating the flow of information to guarantee continuity, quality and safety in care. High-quality nursing documentation is frequently lacking; the implementation of computerized decision support systems is expected to improve clinical practice and nursing documentation.Aim: The present study aimed at investigate the effects of a computerized decision support system and an educational program as intervention strategies for improved nursing documentation practice on pressure ulcers and malnutrition in nursing homes.Design, setting and participants: An intervention study with two intervention groups and one control group was used. Fifteen nursing homes in southern Norway were included. A convenience sample of electronic healthcare records from 46 units was included. Inclusion criteria were records with presence of pressure ulcers and/or malnutrition. The residents were assessed before and after an intervention of a computerized decision support system in the electronic healthcare records. Data were collected through a review of 150 records before (2007) and 141 records after the intervention (2009).Methods: The nurses in intervention group 1 were offered educational sessions and were trained to use the computerized decision support system, which they used for eight months in 2008 and 2009. The nurses in intervention group 2 were offered the same educational program but did not use the computerized decision support system. The nurses in the control group were not subject to any intervention. The resident records were examined for the completeness and comprehensiveness of the documentation of pressure ulcers and malnutrition with three data collection forms and the data were analyzed with non-parametric statistics.Results: The implementation of the computerized decision support system and the educational program resulted in a more complete and comprehensive documentation of pressure ulcer- and malnutrition-related nursing assessments and nursing interventions.Conclusion: This study provides evidence that the computerized decision support system and an educational program as implementation strategies had a positive influence on nursing documentation practice.

Identification of adipocyte genes regulated by caloric intake
- 2011

Ingår i: Journal of Clinical Endocrinology and Metabolism. - : Endocrine society. - 0021-972X .- 1945-7197. ; 96:2, s. E413-E418

Tidskriftsartikel (refereegranskat)abstract
- CONTEXT: Changes in energy intake have marked and rapid effects on metabolic functions and some of the effects may be due to changes in adipose tissue gene expression that precede alterations in body weight. OBJECTIVE: To identify genes in adipose tissue regulated by changes in caloric intake independent of changes in body weight. RESEARCH DESIGN AND METHODS: Obese subjects were given a very-low calorie diet (VLCD; 450 kcal/day) for 16 weeks. After the diet, ordinary food was gradually reintroduced during 2 weeks while there were minimal changes in body weight. Adipose tissue gene expression was measured by microarray analysis. First, genes regulated during caloric restriction and in the opposite direction during the weight stable re-feeding phase were identified. To verify opposite regulation to that observed during caloric restriction, identified genes were further analyzed using adipocyte expression profiles from healthy subjects before and after overfeeding. Results were confirmed using real time PCR or immunoassay. RESULTS: Using a significance level of p<0.05 for all comparisons, 52 genes were downregulated and 50 were up-regulated by caloric restriction and regulated in the opposite direction by re-feeding and overfeeding. Among these were genes that affect lipogenesis (ACLY, ACACA, FASN, SCD), protein synthesis (4EBP1, 4EBP2), beta-oxidation (CPT1B), liberation of fatty acids (CIDEA) and glyceroneogenesis (PCK2). Interestingly, several of these are under control of the master regulator mTOR. CONCLUSIONS: The observed transcriptional changes indicate that mTOR plays a central role in the control of diet-regulated adipocyte genes involved in lipogenesis and protein synthesis.

- Context: Cell death-inducing DFFA-like effector A (CIDEA) could be a potential target for the treatment of obesity via the modulation of metabolic rate, based on the findings that CIDEA inhibits the brown adipose tissue uncoupling process in rodents. Objective: To investigate the putative link between CIDEA and basal metabolic rate in humans, and to further elucidate the role of CIDEA in human obesity. Design: We have explored CIDEA gene expression in adipose tissue in two different human studies: A cross-sectional and population-based study assessing body composition and metabolic rate (Mölndal Metabolic study, n=92), and a longitudinal intervention-study of obese subjects treated with a very low calorie diet (VLCD study, n=24). Results: The CIDEA gene was predominantly expressed in adipocytes as compared to other human tissues. CIDEA gene expression in adipose tissue was inversely associated with basal metabolic rate independently of body composition, age and gender (p=0.014). VLCD induced an increase in adipose tissue CIDEA expression (p<0.0001) with a subsequent decrease in response to refeeding (p<0.0001). Reduced CIDEA gene expression was associated with a high body fat content (p<0.0001) and with high insulin levels (p<0.01). No dysregulation of CIDEA expression was observed in individuals with the metabolic syndrome when compared with BMI-matched controls. In a separate sample of VLCD-treated subjects (n=10), uncoupling protein 1 expression was reduced during diet (p=0.0026) and inversely associated with CIDEA expression (p=0.0014). Conclusion: The findings are consistent with the concept that CIDEA plays a role in adipose tissue energy expenditure.

Health-Related Quality of Life in Postmenopausal Women with Osteoporotic Fractures
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The global burden of osteoporosis includes considerable numbers of fractures, morbidity, mortality and expenses, due mainly to vertebral, hip and forearm fractures. Underdiagnosis and undertreatment are common. Several studies have shown decreased health-related quality of life (HRQOL) after osteoporotic fracture, but there is a lack of data from long-term follow-up studies, particularly regarding vertebral fractures, which are often overlooked despite patients reporting symptoms.Aim: The overall aim of this thesis was to evaluate the usefulness of a recent low-energy fracture as index event in a case-finding strategy for osteoporosis and to describe and analyse long-term HRQOL in postmenopausal women with osteoporotic fracture. The specific aims were to describe bone mineral density and risk factors in women 55-75 years of age with a recent low-energy fracture (I), estimate the impact of osteoporotic fractures on HRQOL in women three months and two years after a forearm, proximal humerus, vertebral or hip fracture (II), investigate the changes and long-term impact of vertebral or hip fracture on HRQOL in women prospectively between two and seven years after the inclusion fracture (III), and describe how HRQOL and daily life had been affected in women with vertebral fracture several years after diagnosis (IV).Design and methods: Data were collected from southern Sweden between 1998 and 2008. A total of 303 women were included in Study I, and this group served as the basis for Studies II (n=303), III (n=67), and IV (n=10). A cross-sectional observational, case-control design (I), and a prospective longitudinal observational design (II-III) were used. In Study IV a qualitative inductive approach with interviews was used and data were analysed using a qualitative conventional content analysis.Results: The type of recent fracture and number of previous fractures are important information for finding the most osteoporotic women in terms of severity (I). Hip and vertebral fractures in particular have a significantly larger impact on HRQOL evaluated using the SF-36 than do humerus and forearm fractures, both during the three months after fracture and two years later, compared between the different fracture groups and the reference population (II). Women who had a vertebral fracture as inclusion fracture had remaining pronounced reduction of HRQOL at seven years. At the mean age of 75.5 years (±4.6 SD), the prevalence of vertebral fracture suggests more negative long-term impact on HRQOL, more severe osteoporosis and a poorer prognosis than a hip fracture does, and this effect may have been underestimated in the past (III). Study IV demonstrates that the women’s HRQOL and daily life have been strongly affected by the long-term impact of the vertebral fracture several years after diagnosis. The women strive to maintain their independence by trying to manage different types of symptoms and consequences in different ways.Conclusions and implications: Type and number of fractures should be taken into account in the case-finding strategy for osteoporosis in postmenopausal women between 55 and 75 years of age. The long-term reduction of HRQOL in postmenopausal women (age span 55-75 yr) with vertebral fracture emerged clearly, compared to women with other types of osteoporotic fractures and references in this thesis. The results ought to be taken into consideration when developing guidelines for more effective fracture prevention and treatment, including non-pharmacological intervention for women with osteoporotic fractures, with highest priority placed on vertebral fractures and multiple fractures, to increase or maintain HRQOL.

- Ion implantation is an important technique for a successful implementation of commercial SiC devices. Much effort has also been devoted to optimising implantation and annealing parameters to improve the electrical device characteristics. However, there is a severe lack of understanding of the fundamental implantation process and the generation and annealing kinetics of point defects and defect complexes. Only very few of the most elementary intrinsic point defects have been unambiguously identified so far. To reach a deeper understanding of the basic mechanisms SiC samples have been implanted with a broad range of ions, energies, doses, etc., and the resulting defects and damage produced in the lattice have been studied with a multitude of characterisation techniques. In this contribution we will review some of the results generated recently and also try to indicate where more research is needed. In particular, deep level transient spectroscopy (DLTS) has been used to investigate point defects at very low doses and transmission electron microscopy (TEM) and Rutherford backscattering spectrometry (RBS) are used for studying the damage build-up at high doses.

Increasing Fecal Butyrate in Ulcerative Colitis Patients by Diet : Controlled Pilot Study
- 2003

Tidskriftsartikel (refereegranskat)abstract
- Topical butyrate has been shown to be effective in the treatment of ulcerative colitis (UC). Butyrate is derived from colonic fermentation of dietary fiber, and our aim was to study whether UC patients could safely increase the fecal butyrate level by dietary means. We enrolled 22 patients with quiescent UC (mean age, 44 years; 45% women; median time from last relapse, 1 year) in a controlled pilot trial lasting 3 months. The patients were instructed to add 60 g oat bran (corresponding to 20 g dietary fiber) to the daily diet, mainly as bread slices. Fecal short-chain fatty acids (SCFAs) including butyrate, disease activity, and gastrointestinal symptoms were recorded every 4 weeks. During the oat bran intervention the fecal butyrate concentration increased by 36% at 4 weeks (from 11 +/- 2 (mean +/- SEM) to 15 +/- 2 mumol/g feces) (p < 0.01). The mean butyrate concentration over the entire test period was 14 +/-1 μmol/g feces (p < 0.05). Remaining fecal SCFA levels were unchanged. No patient showed signs of colitis relapse. Unlike controls, the patients showed no increase in gastrointestinal complaints during the trial. Yet patients reporting abdominal pain and reflux complaints at entry showed significant improvement at 12 weeks that returned to baseline 3 months later. This pilot study shows that patients with quiescent UC can safely take a diet rich in oat bran specifically to increase the fecal butyrate level. This may have clinical implications and warrants studies of the long-term benefits of using oat bran in the maintenance therapy in UC.

A global assay of haemostasis which uses recombinant tissue factor and tissue-type plasminogen activator to measure the rate of fibrin formation and fibrin degradation in plasma

Tidskriftsartikel (refereegranskat)abstract
- The global assay of Overall Haemostasis Potential we previously described has been refined. The coagulation cascade in platelet-poor plasma is triggered by adding a minimal dose of recombinant tissue factor together with purified phospholipids and calcium; fibrinolysis is initiated by adding recombinant tissue type-plasminogen activator in a concentration similar to what can be obtained during thrombolysis. Numerical differentials of optical densities reflecting rates of fibrin formation and degradation are calculated by a new software, and the Coagulation Profile (Cp) and the Fibrinolysis Profile (Fp) are determined. The combined effect of these counteractive systems is expressed as a ratio of Cp to Fp, called the Overall Haemostasis Index. Commercially available coagulant-deficient patient plasma samples and plasma with various amounts of added PAI-1 are examined; changes of fibrin turbidity demonstrate that this assay can determine Cp and Fp in a physiologically relevant way. Increased Cp and decreased Fp in prothrombotic patients, as well as expected effects of heparin or a thrombin inhibitor on Cp and Fp, suggest that our method can detect hypercoagulability and assist in monitoring antithrombotic treatment. Ongoing studies will show whether this simple assay can be of value in clinical routine.

- Aim To evaluate the economic and clinical burden associated with poor glycaemic control in Sweden, in people with type 2 diabetes (T2D) initiating first-line glucose-lowering therapy. Materials and Methods Population data were obtained from Swedish national registers. Immediate glycaemic control was compared with delays in achieving control of 1 and 3 years, with outcomes projected over 3, 10 and 50 years in the validated IQVIA CORE Diabetes Model. Glycaemic control was defined as glycated haemoglobin (HbA1c) targets of 52, 48 and 42 mmol/mol, as recommended in Swedish guidelines, according to age and disease duration. Costs (expressed in 2019 Swedish krona [SEK]) were accounted from a Swedish societal perspective. Results Immediate glycaemic control was associated with population-level cost savings of up to SEK 279 million and SEK 673 million versus delays of 1 and 3 years, respectively, as well as small population-level life expectancy benefits of up to 1305 and 2590 life years gained. Reduced levels of burden were a result of lower incidence and delayed time to onset of diabetes-related complications. Conclusions Even in people with T2D initiating first-line glucose-lowering therapy, the economic burden of poor glycaemic control in Sweden is substantial, but could be reduced by early and effective treatment to achieve glycaemic targets.

Tidskriftsartikel (refereegranskat)abstract
- Background: Patients with acute myocardial infarction often have long decision times before seeking medical care. The decision time is influenced by knowledge of AMI-symptoms, psychological factors and the response of people near the patient to the symptoms.Aim:To investigate and compare the knowledge of AMI, intended actions in response to AMI-symptoms and attitudes toward seeking medical care of patients and the general public. Method: This was a multicentre study with descriptive and comparative design, using questionnaires as an instrument. The population consisted of AMI-patients and representatives of the general public.Results: There was good knowledge about typical AMI-symptoms among the participants. The majority thought an AMI always starts suddenly. Patients did not know more about the time-dependency of treatment outcome than the general public. A greater proportion of the general public would contact an additional person before consulting medical professionals.Conclusions: Patients had no better knowledge about AMI than the general public, but would more commonly act appropriately in case of AMI-symptoms.

- Background: Time is crucial when an acute myocardial infarction (AMI) occurs, but patients often wait before seeking medical care. Aim: To investigate and compare patients' and relatives' knowledge of AMI, attitudes toward seeking medical care, and intended behaviour if AMI-symptoms occur. Methods: The present study was a descriptive, multicentre study. Participants were AMI-patients <= 75 years (n = 364) and relatives to AMI-patients (n = 319). Questionnaires were used to explore the participants' knowledge of AMI and attitudes toward seeking medical care. Results: Both patients and relatives appeared to act more appropriate to someone else's chest pain than to their own. Patients did not have better knowledge of AMI-symptoms than relatives. Women would more often contact someone else before seeking medical care. A greater percentage of elderly (65-75 years), compared to younger individuals, reported that they would call for an ambulance if chest pain occurred. Conclusions: There were only minor differences between patients and relatives, regarding both knowledge and attitudes. It seems easier to act correctly as a bystander than as a patient. Therefore, in order to decrease patients' delay time it is important to educate relatives as well as patients on how to respond to symptoms of an AMI.

Tidskriftsartikel (refereegranskat)abstract
- Background Over the next decade, the number of osteoarthritis consultations in health care is expected to increase. Physiotherapists may be considered equally qualified as primary assessors as physicians for patients with knee osteoarthritis. However, economic evaluations of this model of care have not yet been described. To determine whether physiotherapists as primary assessors for patients with suspected knee osteoarthritis in primary care are a cost-effective alternative compared with traditional physician-led care, we conducted a cost-effectiveness analysis alongside a randomized controlled pragmatic trial. Methods Patients were randomized to be assessed and treated by either a physiotherapist or physician first in primary care. A cost-effectiveness analysis compared costs and effects in quality adjusted life years (QALY) for the different care models. Analyses were applied with intention to treat, using complete case dataset, and missing data approaches included last observation carried forward and multiple imputation. Non-parametric bootstrapping was conducted to assess sampling uncertainty, presented with a cost-effectiveness plane and cost-effectiveness acceptability curve. Results 69 patients were randomized to a physiotherapist (n = 35) or physician first (n = 34). There were significantly higher costs for physician visits and radiography in the physician group (p < 0.001 and p = 0.01). Both groups improved their health-related quality of life 1 year after assessment compared with baseline. There were no statistically significant differences in QALYs or total costs between groups. The incremental cost-effectiveness ratio for physiotherapist versus physician was savings of 24,266 euro/lost QALY (societal perspective) and 15,533 euro/lost QALY (health care perspective). There is a 72-80% probability that physiotherapist first for patients with suspected knee osteoarthritis is less costly and differs less than +/- 0.1 in QALY compared to traditional physician-led care. Conclusion These findings suggest that physiotherapist-led care model might reduce health care costs and lead to marginally less QALYs, but confidence intervals were wide and overlapped no difference at all. Health consequences depending on the profession of the first assessor for knee osteoarthritis seem to be comparable for physiotherapists and physicians. Direct access to physiotherapist in primary care seems to lead to fewer physician consultations and radiography. However, larger clinical trials and qualitative studies to evaluate patients' perception of this model of care are needed.

- Fracture risk in GHD patients is not definitely established. Studying fracture incidence in 832 patients on GH therapy and 2581 matched population controls, we recorded a doubled fracture risk in CO GHD women, but a significantly lower fracture risk in AO GHD men. Introduction: The objective of this study was to evaluate fracture incidence in patients wilh confirmed growth hormone deficiency (GHD) on replacement therapy (including growth hormone [GH]) compared with population controls, while also taking potential confounders and effect modifiers into account. Materials and Methods: Eight hundred thirty-two patients with GHD and 2581 matched population controls answered a questionnaire about fractures and other background information. Incidence rate ratio (IRR) and 95% CI for first fracture were estimated. The median time on GH therapy for childhood onset (CO) GHD men and women was 15 and 12 yr, respectively, and 6 and 5 yr for adult onset (AO) GHD men and women, respectively. Results: A more than doubled risk (IRR, 2.29; 95% CI, 1.23-4.28) for nonosteoporotic fractures was recorded in women with CO GHD, whereas no risk increase was observed among CO GHD men (IRR. 0.61) and AO GHD women (IRR, 1.08). A significantly decreased incidence of fractures (IRR, 0.54; 95% CI 0.34-0.86) was recorded in AO GHD men. Conclusions: Increased fracture risk in CO GHD women can most likely be explained by interaction between oral estrogen and the GH-IGF-I axis. The adequate substitution rate of testosterone (90%) and GH (94%) may have resulted in significantly lower fracture risk in AO GHD men.

- Context: The impact of long-term GH replacement on cerebrovascular and cardiovascular diseases and diabetes mellitus in hypopituitary patients is unknown. Objective: The incidence of nonfatal stroke and cardiac events, and prevalence of type 2 diabetes mellitus ( T2D) and cardioprotective medication were compared between cohorts of GH-deficient (GHD) patients and population controls. Design and Participants: The incidence of nonfatal stroke and cardiac events was estimated retrospectively from questionnaires in 750 GHD patients and 2314 matched population controls. A prevalence of T2D and cardioprotective medication was recorded at the distribution of questionnaires. Time since first pituitary deficiency to start of GH therapy was 4 and 2 yr, and time on GH therapy was 6 yr for GHD women and men, respectively. Results: Lifelong incidence of nonfatal stroke was tripled in GHD women and doubled in GHD men, but a decline was seen in both genders during periods after first pituitary hormone deficiency and GHD, during which most patients had GH therapy. The lifelong incidence of nonfatal cardiac events declined in GHD men during first pituitary hormone deficiency and GHD periods. GHD women had a higher prevalence of T2D and lipid-lowering medication, whereas GHD men had a higher prevalence of antihypertensive medication. Conclusions: The declined risks of nonfatal stroke in both genders and of nonfatal cardiac events in GHD men during periods on GH replacement may be caused by prescription of cardioprotective drugs and 6-yr GH replacement. GHD women had an increased prevalence of T2D, partly attributed to higher body mass index and lower physical activity.

- OBJECTIVE: Using gene expression profiling, we aimed to identify genes that are predominantly expressed in human carotid atherosclerotic plaques. Such genes may be important in atherogenesis and pathophysiology of the plaque, and genes that encode for secreted proteins may be potential biomarkers for atherosclerosis and cardiovascular disease. METHODS: DNA microarray generated expression profiles of human carotid atherosclerotic plaques were compared to expression profiles of 80 different human tissues and cell types, to identify plaque-specific genes. RESULTS: We identified the chemokine (C-C motif) ligand 18 (CCL18) as predominantly expressed in human carotid plaque. Immunohistochemistry showed that CCL18 protein was localized to a subset of macrophages in carotid plaques. Monocyte-derived macrophages from subjects with atherosclerosis had threefold higher expression of CCL18 than macrophages from control subjects (p=0.012). Subjects with A/G genotype of the rs2015086 SNP in the promoter region of the CCL18 gene had threefold higher macrophage expression of CCL18 than subjects with A/A genotype (p=0.049), but we found no association of this SNP with an increased risk of coronary heart disease. We also compared serum levels of CCL18 from subjects with symptomatic carotid artery disease with control subjects. There were no differences in serum levels of CCL18 between the two groups, however CCL18 correlated with measurements of adiposity. CONCLUSION: CCL18 is predominantly expressed in human atherosclerotic plaques and may participate in the atherosclerotic plaque formation.
