Journal article (peer-reviewed)abstract
- Purpose: To investigate the possibility of constructing a multiprofessional cross-cultural measure of functioning after stroke across categories of the International Classification of Functioning, Disability and Health (ICF). Method: Data on 757 stroke survivors from China, Germany, Italy, and Sweden, including ratings of 15 categories from the Brief ICF Core Set for stroke, were analyzed using the Rasch model. Unidimensionality, reliability, fit of the ICF categories to the model, ordering of response options of the ICF qualifier, and presence of differential item functioning (DIF) were studied. Results: Of the 15 ICF categories, response options for 7 categories were collapsed, 5 categories were deleted due to misfit, and 4 ICF categories showed DIF for country and were accordingly split into country-specific categories. The proposed final clinical measure consists of 20 ICF categories (6 categories were country-common) with an overall fit statistic of χ2180 = 184.87, P = .386, and a person separation index of r = 0.72, which indicates good reliability. Based on an individual's functioning after stroke, the ratings across the different ICF categories can be summed on an interval scale ranging from 0 to 100. Conclusion: A construction of a cross-cultural clinical measure after stroke based on ICF categories across body functions, structures, and activities and participation was possible. With this kind of clinical measure, stroke survivors' functional levels can be compared even across countries. Despite the promising results, further studies are necessary to develop definitive measures based on ICF categories.

Journal article (peer-reviewed)abstract
- BACKGROUND: In line with patient-centered health care, it is necessary to understand patients' perceptions of health. How stroke survivors perceive their health at different time points after stroke and which factors are associated with these feelings provide important information about relevant rehabilitation targets. OBJECTIVE: This study aimed to identify the independent factors of health-related quality of life (HRQoL) from a biopsychosocial perspective using the methods of multivariate regression at 3 different time points poststroke. METHODS: Included in the study were 99 patients from stroke units with diagnosed first-ever stroke. At admission and at 6 weeks, 3 months, and 1 year poststroke, HRQoL was assessed using the EuroQoL-5D Visual Analogue Scale (EQ-5D VAS). Consequences in Body Functions and Activities and Participation, and Environmental Factors were documented using 155 categories of the International Classification of Functioning, Disability and Health (ICF) Core Set for Stroke. RESULTS: For a period of 1 year, problems with recreation and leisure, personality functions, energy and drive functions, and gait pattern functions were repeatedly associated with worse HRQoL. Whereas Body Functions and Activities and Participation explained more than three-fourths of the variances of HRQoL at 6 weeks and 3 months (R (2) = 0.80-0.93), the variation at 1 year was best explained by either Body Functions or Environmental Factors (R (2) = 0.51). CONCLUSIONS: The results indicate the importance of Body Functions and Activities and Participation (mainly personality functions and recreation and leisure) on HRQoL within 3 months poststroke, but increased impact of Environmental Factors on HRQoL at 1 year.

Relapsed Hodgkin's lymphoma : immunostaining patterns in relation to survival
- 2002
-
In: Leukemia and Lymphoma. - : Informa UK Limited. - 1042-8194 .- 1029-2403. ; 43, s. 1253-
-
Journal article (peer-reviewed)abstract
- Patients with relapsing Hodgkin's lymphoma (HL) have a rather poor prognosis and mechanisms that lead to resistance to therapy are poorly understood. Our aims were to investigate the immunohistochemical staining patterns of Rb (retinoblastoma protein) and the p53 tumour suppressor protein in HL at initial presentation and at relapse in order to elucidate a possible role in disease progression and resistance to therapy. Further to evaluate the presence and prognostic importance of Epstein-Barr virus (EBV) and anaplastic lymphoma kinase (ALK). Eighty-one cases of relapsing HL were reexamined histopathologically and immunostained for the expression of p53, Rb, ALK and CD30. EBV was detected with LMP-1 stainings and in situ hybridisation for EBER. Clinical data were extracted from the Swedish National Health Care Programme for HL. Median follow-up time was six years (range 0-12) from the date of relapse. The majority of cases were positive for p53 and Rb both at presentation and at relapse, though to a different extent. Both an increase and a decrease in the proportion of stained tumour cells were observed. None of our cases was ALK-positive and 44% were EBV-positive. No specific staining pattern was directly correlated to survival. In 12 patients a switch in HL subtype from diagnosis to relapse was observed and the five-year Hodgkin-specific survival (HLS) was statistically significantly inferior, 37 vs 81% (p = 0.002), in those patients. We found a significant relation between the expression of p53 and EBV at diagnosis and relapse, indicating a clonal relationship. We were unable to find any specific staining pattern of p53 or Rb, affecting survival.

Förenklad utvärdering av inomhusluftkvaliteten på ett kontor - en metodstudie
- 2006
-
Reports (other academic/artistic)abstract
- De mätningar som presenteras i denna rapport har utförts för att utvärdera ett förenklat mätkoncept för bestämning av luftkvaliteten inomhus. Mätkonceptet har utvecklats med syftet att personal, t ex fastighetsskötare, efter kortare information själva ska kunna utföra mätningen. Mätutrustningen består av direktvisande instrument samt aktiva och passiva provtagare. Utrustningen placeras ut vid mätstart och tas in vid avslutad mätning. Provtagarna behöver ingen särskild tillsyn under mätningen. De tagna proverna och direktvisande instrument skickas till laboratoriet för analys respektive tömning på data och sammanställs. Erhållet svar jämförs med uppställda kriterier för luftkvaliteten (se IVL-rapport B1506). Metodtesten utfördes i en relativt nybyggd kontorsfastighet belägen i tätort nära en större trafikled. Mätresultaten visar att enkla mätningar av några vanliga kemiska ämnen är en användbar metod vid miljöklassning av fastigheter

Development and psychometric evaluation of the radiographers’ competence scale
- 2012
-
In: Open Journal of Nursing. - : Scientific Research Publishing, Inc.. - 2162-5336 .- 2162-5344. ; 2:2, s. 85-96
-
Journal article (peer-reviewed)abstract
- Assessing the competence of registered radiographers’ clinical work is of great importance because of the recent change in nursing focus and rapid technological development. Self-assessment assists radiographers to validate and improve clinical practice by identifying their strengths as well as areas that may need to be developed. The aim of the study was to develop and psychometrically test a specially designed instrument, the Radiographers Competence Scale (RCS). A cross sectional survey was conducted comprising 406 randomly selected radiographers all over Sweden. The study consisted of two phases; the development of the instrument and evaluation of its psychometric properties. The first phase included three steps: 1) construction of the RCS; 2) pilot testing of face and content validity; and 3) creation of a web-based 54-item questionnaire for testing the instrument. The second phase comprised psychometric evaluation of construct validity, internal consistency reliability and item reduction. The analysis reduced the initial 54 items of the RCS to 28 items. A logical two-factor solution was identified explaining 53.8% of the total variance. The first factor labelled “Nurse initiated care” explained 31.7% of the total variance. Factor 2 labelled “Technical and radiographic processes” explained 22.1% of the total variance. The scale had good internal consistency reliability, with a Cronbach’s alpha of 0.87. The RCS is a short, easy to administer scale for capturing radiographers’ competence levels and the frequency of using their competence. The scale was found to be valid and reliable. The self-assessment RCS can be used in management, patient safety and quality improvement to enhance the radiographic process.

Radiographers’ Professional Competence : Development of a context-specific instrument
- 2012
-
Doctoral thesis (other academic/artistic)abstract
- Aims: The overall aim of this thesis was to explore and describe radiographers‟ professional competence based on patients‟ and radiographers‟ experiences and to develop a context-specific instrument to assess the level and frequency of use of radiographers‟ professional competence.Methods: The design was inductive and deductive. Both qualitative and quantitative methods were used. The data collection methods comprised interviews (Studies I-II) and questionnaires (Studies III-IV). The subjects were patients in study I and radiographers in studies II-IV. In study I, 17 patients were interviewed about their experiences of the encounter during radiographic examinations and treatment. The interviews were analysed using qualitative content analysis. In study II, 14 radiographers were interviewed to identify radiographers‟ areas of competence. The critical incident technique was chosen to analyse the interviews. Studies III and IV were based on a national cross-sectional survey of 406 randomly selected radiographers. Study III consisted of two phases; designing the Radiographer Competence Scale (RCS) and evaluation of its psychometric properties. A 42-item questionnaire was developed and validated by a pilot test (n=16) resulting in the addition of 12 items. Thus the final RCS comprised a 54-item questionnaire, which after psychometric tests was reduced to 28 items. In study IV, the 28-item questionnaire served as data. The level of competencies was rated on a 10-point scale, while their use was rated on a six-point scale.Results: In study I, the female patients‟ comprehensive understanding was expressed as feelings of vulnerability. The encounters were described as empowering, empathetic, mechanical and neglectful, depending on the radiographers‟ skills and attitudes. Study II revealed two main areas of professional competence, direct patient-related and indirect patient-related. The first focused on competencies in the care provided in close proximity to the patient and the second on competencies used in the activities of the surrounding environment. Each of the two main areas was divided into four categories and 31 sub-categories that either facilitated or hindered good nursing care. In study III the analysis condensed the 54-item questionnaire in two steps, firstly by removing 12 items and secondly a further 14 items, resulting in the final 28-item RCS questionnaire. Several factor analyses were performed and a two factor-solution emerged, labelled; “Nurse initiated care” and “Technical and radiographic processes”. The psychometric tests had good construct validity and homogeneity. The result of study IV demonstrated that most competencies in the RCS received high ratings both in terms of level and frequency of use. Competencies e.g. „Adequately informing the patient‟, „Adapting the examination to the patient‟s prerequisites and needs‟ and „Producing accurate and correct images‟ were rated the highest while „Identifying and encountering the patient in a state of shock‟ and „Participating in quality improvement regarding patient safety and care‟ received the lowest ratings. The total score of each of the two dimensions had a low but significant correlation with age and years in present position. The competence level correlated with age and years in present position in both dimensions but not with the use of competencies in the “Nurse initiated care” dimension.Conclusion: This thesis has shown that professional competence is important in the encounter between patient and radiographer. It has also demonstrated that radiographers‟ self-rated professional competence is based on nursing, technological and radiographic knowledge. From a radiographer‟s perspective, „Nurse initiated care‟ and „Technical and Radiographic processes‟ are two core dimensions of Radiographer Competence Scale. The 28-item questionnaire regarding level and frequency of use of competence is feasible to use to measure radiographers‟ professional competence.

Journal article (peer-reviewed)abstract
- OBJECTIVES: To describe radiographers' self-assessed level and use of competencies as well as how sociodemographic and situational factors are associated with these competencies, particularly related to work experience.METHODS: A cross-sectional design was employed. Radiographers (n = 406) completed the self-administered 28-item questionnaire encompassing two dimensions: 'Nurse-initiated care' and 'Technical and radiographic processes'. The level of competencies was rated on a 10-point scale and the frequency of use on a 6-point scale.RESULTS: Most competencies received high ratings both in terms of level and frequency of use. In 'Nurse-initiated care' the competency 'Adequately informing the patient' was rated the highest, while 'Identifying and encountering the patient in a state of shock' and 'Participating in quality improvement regarding patient safety and care' received the lowest ratings. In 'Technical and radiographic processes' the highest rated competencies were 'Adapting the examination to the patient's prerequisites and needs' and 'Producing accurate and correct images'. The lowest frequency of use was 'Preliminary assessment of images'.CONCLUSION: The main findings underline the radiographers' high competency in both 'Nurse-initiated care' and 'Technical and radiographic processes'. The lower rated competencies emphasise the importance of continuous professional education and quality improvement.MAIN MESSAGES :• Assessing radiographers' clinical competencies is fundamental for ensuring professional standards.• Most competencies received high ratings both in the nursing and in the radiographic dimensions.• The highest rated competencies focussed on information and adaptability to the patients needs.• The lowest rated competencies focussed on encountering the patient in shock and image assessments.• Age, years in present position and work place only explained a relatively small part of competency.

Conference paper (peer-reviewed)abstract
- The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micro structure, morphology and sizing of the fibres, the friction materials, the deformation rates and applied loads.

Effektiva åtgärder mot exponering för isocyanater i bilverkstäder
- 2002
-
Reports (other academic/artistic)abstract
- Isocyanater är en grupp ämnen som är allergiframkallande också i mycket låga halter. Isocyanater är den vanligaste orsaken till yrkesallergier och det är därför viktigt att skydda sig mot exponering för isocyanater. Mot bakgrund av mätningar av exponering för isocyanater och aminer vid olika typarbeten i bilverkstäder samt tester och utvärderingar av olika åtgärder, rekommenderas ett antal effektiva åtgärder mot exponering för isocyanater. Följande åtgärder föreslås: Vid MIG-svetsning ska svetspistol med integrerat utsug, anslutet till högvakuum användas i kombination med punktutsug och renslipning av plåt 3-5 cm. Vid motståndspunktsvetsning har ett integrerat utsug visats fungera bra, men något sådant finns ännu inte kommersiellt tillgängligt. Därför behöver andningsskydd användas vid motståndspunktsvetsning. Kapning och slipning bör göras med verktyg som inte alstrar så mycket värme, cirkelsåg med roterande klinga eller sticksåg (kapning) och planslipmaskin med integrerat utsug, bandslipmaskin eller roterande slipmaskin med Scotch Brite (slipning). Vid värmeriktning, krympning och hårdlödning ska ytorna renslipas och punktutsug användas. Avskärmning med svetsduk och extra utsug minskar spridningen av isocyanater ytterligare. Andningsskydd (helst tryckluftsmatat) behöver användas. I rapporten diskuteras även andra åtgärder som avskilda utrymmen, allmänventilation, användning av punktutsug mm.
