Tidskriftsartikel (refereegranskat)abstract
- To develop a cell-free system that can be used to measure cytokine bioactivity we have designed a soluble hybrid molecule consisting of the extracellular domain of the GH-receptor (GHR) and the intracellular domain of the epidermal growth factor receptor (EGFR). A DNA construct encoding this hybrid-receptor was inserted into a baculoviral expression vector and expressed in Sf9-cells. Activation of the hybrid-receptor by ligand-induced dimerization can be measured as the incorporation of radiolabeled phosphate into a biotinylated tyrosine kinase peptide substrate. The kinase activity in samples stimulated with GH (10 ng/ml) increased 5-fold compared to samples without addition of GH. This is the first example of a functional hybrid-receptor where the transmembrane domain has been deleted. Our results suggest that such hybrid-receptors may be used for detection of GH and other cytokine-receptor activating substances in biological fluids.

- The aim of this study was to explore the everyday life experiences of people one year after corrective osteotomy following a symptomatic, malunited, distal radius fracture. Semi-structured interviews were conducted with twenty respondents, median age 65 (22-81) years. The respondents were recruited consecutively. The interviews were subjected to qualitative content analysis. Three authors took part in the analysis. The result is presented as one theme, 'Daily life works again' with five categories: Relief of inconveniences and symptoms, Managing new symptoms and complications, Regaining abilities, Normalised social relationships, Increased wellbeing. The symptoms had declined in severity, some participants regarded themselves as fully restored and used their hand again without hesitation. Others were still bothered by their wrist occasionally and a few had to manage complications. The participants had regained the ability to perform many everyday life activities and reported increased independence and less irritation between spouses, as well as increased wellbeing. One year after a corrective osteotomy following malunion of a distal radius fracture, the patients' experiences represent a continuum. Some are still restricted by their wrist occasionally, the majority experience an increased ease in their performance of activities of daily life and some regard themselves as fully restored. The recovery has a positive impact on social relationships and the patients' wellbeing.

- Purpose: The aim of this study was to explore the everyday life experiences of people suffering from a symptomatic, malunited, distal radius fracture. Method: Qualitative interviews were conducted with twenty respondents, median age 59 [16–85] years. The interviews were subjected to qualitative content analysis. Results: The result, presented as one main theme with categories and subcategories, describes the impact of the injury. Everyday life was affected in all participants, very much in a few highly valued activities such as sports and work, whenever the hand was used, or even at rest. This study indicates that the injury has an impact on the ability to move around, other parts of the body, sleep, emotions, self-perception and relationships. It also shows that the patients used several strategies to manage the situation. Conclusion: The malunion of a distal radius fracture has a negative impact on a wide range of daily activities, as well as other aspects of daily life. There is a need for information between caregivers and patients, and clear routines, once a malunion has occurred.Implications for rehabilitation The symptomatic malunion of a distal radius fracture should be acknowledged as a complex condition requiring comprehensive interventions Technical equipment, braces and new solutions on practical problems was necessary to manage everyday life and should be a focus of intervention for this patient group The consequences of the injury was not only restricted activity performance but also affected social relationships and emotions Information about fracture healing and how a malunion can occur, as well as information on how much the wrist can be loaded at different time points, is important to reduce anxiety. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.

Early coordinated rehabilitation in acute phase after hip fracture - a model for increased patient participation
- 2017
-
Ingår i: Bmc Geriatrics. - : Springer Science and Business Media LLC. - 1471-2318. ; 17:240
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Studies have shown that patients with hip fracture treated in a Comprehensive Geriatric Care (CGC) unit report better results in comparison to orthopaedic care. Furthermore, involving patients in their healthcare by encouraging patient participation can result in better quality of care and improved outcomes. To our knowledge no study has been performed comparing rehabilitation programmes within a CGC unit during the acute phase after hip fracture with focus on improving patients' perceived participation and subsequent effect on patients' function. Methods: A prospective, controlled, intervention performed in a CGC unit and compared with standard care. A total of 126 patients with hip fracture were recruited who were prior to fracture; community dwelling, mobile indoors and independent in personal care. Intervention Group (IG): 63 patients, mean age 82.0 years and Control Group (CG): 63 patients mean age 80.5 years. Intervention: coordinated rehabilitation programme with early onset of patient participation and intensified occupational therapy and physiotherapy after hip fracture surgery. The primary outcome measure was self-reported patient participation at discharge. Secondary outcome measures were: TLS-BasicADL; Bergs Balance Scale (BBS); Falls Efficacy Scale FES(S); Short Physical Performance Battery (SPPB) and Timed Up and Go (TUG) at discharge and 1 month and ADL staircase for instrumental ADL at 1 month. Results: At discharge a statistically significant greater number of patients in the IG reported higher levels of participation (p < 0.05) and independence in lower body hygiene (p < 0.05) and dressing (p < 0.001). There were however no statistically significant differences at discharge and 1 month between groups in functional balance and confidence, performance measures or risk for falls. Conclusion: This model of OT and PT coordinated inpatient rehabilitation had a positive effect on patients' perceived participation in their rehabilitation and ADL at discharge but did not appear to affect level of recovery or risk for future falls at 1 month. A large proportion of patients remained at risk for future falls at 1 month in both groups highlighting the need for continued rehabilitation after discharge.

- Aim: To explore patients’ experiences of their recovery after hip fracture surgery and the use of Traffic Light System-BasicADL in their rehabilitation process. Method: Nineteen patients (13 females and 6 males), aged 66–94, were interviewed. A qualitative content analysis method was used for analysis of data. Results: Two categories were identified: ‘Being seen as a person’ with subcategories; Interaction affects trust and security; Information is key to understanding; and Encouragement is essential to promote activity. And ‘Striving for Independence’, with subcategories; Accepting the situation while trying to remain positive; The greener the better, but it’s up to me; Ask me, I have goals; and Uncertainties concerning future. Conclusion: The findings of this study mirror clinical reality. There is a continued need for organisations to reflect over existing practise and question routines and procedures. In order to improve services and provide better quality of care, it is essential to acknowledge the patients’ experiences, needs and preferences and make efforts to accommodate these where possible. Health care professionals must recognise that patients with hip fracture are individuals, with varying needs that change across the continuum of recovery.

Att utvärdera och använda resultaten – vilka avtryck ger bibliotekens utvärderingar i samhället?
- 2013
-
Konferensbidrag (populärvet., debatt m.m.)abstract
- Det har blivit allt viktigare för biblioteken att kunna visa på sin betydelse i samhället. Mätetal och utvärderingar är nödvändiga instrument för att kunna jämföra satsningar på biblioteken med satsningar på andra områden. Men finns det en synergi mellan mätetalen och verksamhetens planer och mål? Hur mäter vi måluppfyllese i biblioteksverksamheten? Finns det kvalitetsindikatorer som vi har gemensamma oavsett bibliotekstyp? Hur kan biblioteksstatistiken användas? Vad gör bibliotekens utvärderingar för avtryck i beslutsprocessen? Vad gör bibliotekens utvärderingar för avtryck i samhället?För att svara på frågorna ovan har expertgruppen påbörjat ett arbete med att kartlägga hur svenska bibliotek arbetar med utvärdering. I det arbetet har vi bland annat sett vikten av ett gemensamt språk mellan bibliotekstyperna i arbetet med utvärderingar och kvalitetsutveckling. Gruppen kommer att under år 2014 publicera ett utvärderingsverktyg för bibliotek. Där kan bibliotek finna vägledning och stöd i valet av utvärderingsmetod, i genomförandet och i nyttjandet av utvärderingars resultat i syfte att utveckla och synliggöra biblioteksverksamheten.I det här papret presenterar vi syftet med vårt arbete och den metod vi har använt samt mer ingående berättar om hur vi har tänkt kring det verktyg som vi i slutet av papret ger en beskrivning av – ett verktyg som går under namnet "Utvärderingshjälpen".Vid konferensen kommer vi att presentera hur en årscykel kan se ut vid ett bibliotek som väljer att använda sig av utvärderingsarbete och systematiskt kvalitetsutveckling i nära relation till måluppfyllelse och till dialog med beslutsfattare samt omgivande samhälle. Vi presenterar också hur "Utvärderingshjälpen" skall kunna användas som stöd i det arbetet.

Variants in BANK1 are associated with lupus nephritis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Lupus nephritis (LN) is a cause of significant morbidity in SLE. While the genetic background to SLE has been well characterized, less is known about genes predisposing to LN.Methods: The study consisted of 2886 SLE patients, including 947 (33%) with LN. The discovery cohort (Sweden, n=1091) and replication cohort 1 (US, n=962) were genotyped on the Immunochip and replication cohort 2 (Norway/Denmark, n=833) on a custom array chip. Allele frequencies were compared between patients with LN, proliferative nephritis, end-stage renal disease and LN negative patients. SNPs with p-value <0.001 in the discovery cohort were analyzed in replication cohort 1. Ten SNPs associated with LN in the discovery cohort (p<0.0002) were genotyped in replication cohort 2. DNA methylation data were available for 180 LN patients from the discovery cohort.Results: In the discovery cohort, six gene loci were associated with LN (p<1x10-4, NFKBIA, CACNA1S, ITGA1, BANK1, OR2Y and PHCA). SNPs in BANK1 showed the strongest association with LN in replication cohort 1 (p=9.5x10-4), with a tendency for an association in replication cohort 2 (p=0.052). In a meta-analysis of all three cohorts the association between LN and BANK1 rs4699259, was strengthened (p=1.7x10‑7). There were no associations to proliferative nephritis or ESRD in the meta-analysis. Methylation quantitative trait loci (MeQTL) effects between a CpG site and several SNPs in BANK1 were identified.Conclusion: Genetic variations in BANK1 are associated with LN. There is evidence for genetic regulation of DNA methylation within the BANK1 locus, however, the exact role of BANK1 in LN pathogenesis remains to be elucidated.

Tidskriftsartikel (refereegranskat)abstract
- The genetic background of lupus nephritis (LN) has not been completely elucidated. We performed a case-only study of 2886 SLE patients, including 947 (33%) with LN. Renal biopsies were available from 396 patients. The discovery cohort (Sweden, n = 1091) and replication cohort 1 (US, n = 962) were genotyped on the Immunochip and replication cohort 2 (Denmark/Norway, n = 833) on a custom array. Patients with LN, proliferative nephritis, or LN with end-stage renal disease were compared with SLE without nephritis. Six loci were associated with LN (p < 1 × 10−4, NFKBIA, CACNA1S, ITGA1, BANK1, OR2Y, and ACER3) in the discovery cohort. Variants in BANK1 showed the strongest association with LN in replication cohort 1 (p = 9.5 × 10−4) and proliferative nephritis in a meta-analysis of discovery and replication cohort 1. There was a weak association between BANK1 and LN in replication cohort 2 (p = 0.052), and in the meta-analysis of all three cohorts the association was strengthened (p = 2.2 × 10−7). DNA methylation data in 180 LN patients demonstrated methylation quantitative trait loci (meQTL) effects between a CpG site and BANK1 variants. To conclude, we describe genetic variations in BANK1 associated with LN and evidence for genetic regulation of DNA methylation within the BANK1 locus. This indicates a role for BANK1 in LN pathogenesis.

Equity in welfare evaluations : the rationale for and effects of distributional weighting
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis addresses the issue of weighted cost-benefit analysis (WCBA). WCBA is a welfare evaluation model where income distribution effects are valued by distributional weighting. The method was developed already in the 1970s. The interest in and applications of this method have increased in the past decade, e.g. when evaluating of global environmental problems. There are, however, still unsolved problems regarding the application of this method. One such issue is the choice of the approach to the means of estimating of the distributional weights. The literature on WCBA suggests a couple of approaches, but gives no clues as to which one is the most appropriate one to use, either from a theoretical or from an empirical point of view. Accordingly, the choice of distributional weights may be an arbitrary one. In the first paper in this thesis, the consequences of the choice of distributional weights on project decisions have been studied. Different sets of distributional weights have been compared across a variety of strategically chosen income distribution effects. The distributional weights examined are those that correspond to the WCBA approaches commonly suggested in literature on the topic. The results indicate that the choice of distributional weights is of importance for the rank of projects only when the income distribution effects concern target populations with low incomes. The results also show that not only the mean income but also the span of incomes, of the target population of the income distribution effect, affects the result of the distributional weighting when applying very progressive non-linear distributional weights. This may cause the distributional weighting to indicate an income distribution effect even though the project effect is evenly distributed across the population. One rational for distributional weighting, commonly referred to when applying WCBA, is that marginal utility of income is decreasing with income. In the second paper, this hypothesis is tested. My study contributes to this literature by employing stated preference data on compensated variation (CV) in a model flexible as to the functional form of the marginal utility. The results indicate that the marginal utility of income decreases linearly with income. Under certain conditions, a decreasing marginal utility of income corresponds to risk aversion. Thus the hypothesis that marginal utility of income is decreasing with income can be tested by analyses of individuals’ behaviour in gambling situations. The third paper examines of the role of risk aversion, defined by the von Neumann-Morgenstern expected utility function, for people’s concern about the problem of ‘sick’ buildings. The analysis is based on data on the willingness to pay (WTP) for having the indoor air quality (IAQ) at home examined and diagnosed by experts and the WTP for acquiring an IAQ at home that is guaranteed to be good. The results indicate that some of the households are willing to pay for an elimination of the uncertainty of the IAQ at home, even though they are not willing to pay for an elimination of the risks for building related ill health. The probability to pay, for an elimination of the uncertainty of the indoor air quality at home, only because of risk aversion is estimated to 0.3-0.4. Risk aversion seems to be a more common motive, for the decision to pay for a diagnosis of the IAQ at home, among young people. Another rationale for distributional weighting, commonly referred to, is the existence of unselfish motives for economic behaviour, such as social inequality aversion or altruism. In the fourth paper the hypothesis that people have altruistic preferences, i.e. that they care about other people’s well being, is tested. The WTP for a public project, that ensures good indoor air quality in all buildings, have been measured in three different ways for three randomly drawn sub-samples, capturing different motives for economic behaviour (pure altruism, paternalism and selfishness). The significance of different questions, and different motives, is analysed using an independent samples test of the mean WTPs of the sub-samples, a chi-square test of the association between the WTP and the sample group membership and an econometric analysis of the decision to pay to the public project. No evidence for altruism, either pure altruism or paternalism, is found in this study.
