- Resolving the genetic basis of complex diseases like rheumatoid arthritis will require knowledge of the corresponding diseases in experimental animals to enable translational functional studies. Mapping of quantitative trait loci in mouse models of arthritis, such as collagen-induced arthritis (CIA), using F(2) crosses has been successful, but can resolve loci only to large chromosomal regions. Using an inbred-outbred cross design, we identified and fine-mapped CIA loci on a genome-wide scale. Heterogeneous stock mice were first intercrossed with an inbred strain, B10.Q, to introduce an arthritis permitting MHCII haplotype. Homozygous H2(q) mice were then selected to set up an F(3) generation with fixed major histocompatibility complex that was used for arthritis experiments. We identified 26 loci, 18 of which are novel, controlling arthritis traits such as incidence of disease, severity and time of onset and fine-mapped a number of previously mapped loci. © The Author 2011.

- In contemporary Ghana, the traditional system and professional social work operate as two parallel systems within the field of social work. The aim of this study was to investigate if and how the teaching of contemporary professional social work in Ghana takes into account traditional actors and practices. The traditional system includes extended family members and traditional authorities such as chiefs or family heads. It formed the social institution that protected and cared for the vulnerable before (Western) social work was introduced as a formal profession in Ghana. A 10-week ethnographic field study was conducted at the Department of Social Work at the University of Ghana. The study employed a qualitative, social constructionist approach, interpreting the results within a theoretical framework of social world theory. The empirical material consisted of interviews with students and teachers, participant observation at lectures, and various documents. The main findings of the study were that professional social workers and traditional actors can be seen as members of two subworlds – the subworld of professional social workers and the subworld of traditional actors. Students and teachers discuss interventions from the perspective of social workers and traditional actors. Their ability to take different perspectives seems to be crucial for localisation – the process by which social work is made relevant to local culture and traditions. The interviewees’ accounts reveal how localisation is not only about culture, but also about social structures and practical considerations. The poor state of the social work profession in Ghana affects interventions in a profound way.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this thesis the female Christian temperance union the White Ribbon is in focus. The White Ribbon was founded in Stockholm in 1900 and it was part of the international organization World’s Woman’s Christian Temperance Union (WWCTU). The organization’s ambition was to create a temperate and moral society, running a variety of philanthropic institutions and adult education, as well as non-alcohol serving restaurants.The aim of the thesis is to study the White Ribbon’s social and political commitment and its ideological approach during the first three decades of the 20th century. The White Ribboners’ ideological approach and culture are problematized in relation to the prevailing and predominant view on women. The organization’s monthly journal has been closely studied and the ideas and practical social and political commitment have been analyzed in a theoretical perspective of social movement theory, according to the Swedish sociologist Håkan Thörn’s methodological framework. This theoretical approach is an instrument to analyze what the White Ribbon identified to be social problems; what was considered to be the reasons for these problems; and what strategy the organization regarded to be the best way to deal with them in order to reach the prognosticated change.The analysis shows that the White Ribbon identified the predominant gender system and the bourgeois view on women as a primary social problem. The organization’s strategy was to eliminate the patriarchal order of the gender system and to change the attitude of people through adult education, information and persuasion. The White Ribbon participated in public debate pursuing temperance and women’s suffrage, and was a lobbyist proposing motions and demanding legislative reforms. The White Ribbon’s ideological approach, as well as their philanthropic activities emanated from a bourgeois ideal of conscientiousness and cultivation, and from an interest in social politics. This was in contrast to the bourgeois view of what the ideal woman should do. From the White Ribboners’ point of view, society could only prosper when women had the same rights as men, and could participate the public sphere and become involved in politics.The study shows that the organization worked hard for equality and democracy, pursuing a feminist and liberal ideology. The White Ribboners regarded themselves, and also acted, as political agents. They introduced and increased women’s possibilities for adult education. They initiated and provided social protection for alcohol addicted women, and for poor and fallen women and girls. These activities must be seen as forms of enterprises and the White Ribboners as entrepreneurs, since these institutions were, in fact, innovations and models for solving problems in order to build a welfare system and to create a temperate and prosperous society. The thesis put forward arguments that the White Ribbon’s social and political work are political innovations and important elements in the process of democratization and, therefore, played an important part in this process.

- The aim of the present study was to identify patterns of background factors related to the early RA patients' conceptions of the cause of the disease. Conceptions from a qualitative study formed the basis for the stratification of 785 patients from the Swedish EIRA study answering a question about their own thoughts about the cause to RA. Logistic regression analyses were used to explore the associations between patients' conceptions and relevant background factors: sex, age, civil status, educational level, anti-cyclic citrullinated peptide antibody (anti-CCP) and smoking habits. The results were presented as odds ratios (OR) with 95% confidence intervals (CI). A conception of family-related strain was strongly associated with being young (OR 0.50; 95% CI 0.33-0.78 for age 58-70 vs. 17-46), female (OR 0.38; 95% CI 0.25-0.60 for male vs. female) and having a high level of education (OR 2.15; 95% CI 1.54-3.01 for university degree vs. no degree). A conception of being exposed to climate changes was associated with being male (OR 1.99; 95% CI 1.24-3.22 for male vs. female), having a low level of education (OR 0.33; 95% CI 0.18-0.58 for university degree vs. no degree) and positive Anti-CCP (OR 1.72; 95% CI 1.03-2.87 for positive vs. negative Anti-CCP). Linking patients' conceptions of the cause of their RA to background factors potentially could create new opportunities for understanding the complexity of the aetiology in RA. Furthermore, this information is important and relevant in the care of patients with early RA.

- We report on highly Mn-doped GaAs nanowires (NWs) of high crystalline quality fabricated by ion beam implantation, a technique that allows doping concentrations beyond the equilibrium solubility limit. We studied two approaches for the preparation of Mn-doped GaAs NWs: First, ion implantation at room temperature with subsequent annealing resulted in polycrystalline NWs and phase segregation of MnAs and GaAs. The second approach was ion implantation at elevated temperatures. In this case, the single-crystallinity of the GaAs NWs was maintained, and crystalline, highly Mn-doped GaAs NWs were obtained. The electrical resistance of such NWs dropped with increasing temperature (activation energy about 70 meV). Corresponding magnetoresistance measurements showed a decrease at low temperatures, indicating paramagnetism. Our findings suggest possibilities for future applications where dense arrays of GaMnAs nanowires may be used as a new kind of magnetic material system.

- Background. The recommended treatment for chronic musculoskeletal pain is multidisciplinary, with a cognitive approach. The aim of this study was to investigate health-related quality of life (HRQoL) outcome after a multidisciplinary treatment with a cognitive approach. Methods. A total of 131 subjects who participated in a multidisciplinary rehabilitation programme (2005-2008) were studied at baseline and after six months, using the Short Form Short Form 36-item Health Survey questionnaire (SF-36) as primary outcome (HRQoL), and the Hospital Anxiety and Depression Scale (HAD) and pain as secondary outcomes and possible baseline predictors for HRQoL. Results. Complete data were available for 97 subjects (85 women, mean age [SD] 44.6 [9.7] years). The SF-36 subscales physical function (PF), general health (GH), vitality (VT), social function (SF) and mental health (MH), the visual analogue scale for pain and the HAD improved significantly (p < 0.05) at follow-up compared with baseline. A pre-treatment probable depression (HAD score ≥11) was associated with a favourable outcome of the SF-36 subscales PF (odds ratio [OR] 5.6; p = 0.01), VT (OR 4.3; p = 0.02) and MH (OR 3.6; p = 0.02). A probable anxiety (HAD score ≥11) was associated with a favourable outcome of PF (OR 2.6; p = 0.05). There was an even stronger association for younger subjects (20-45 years), with probable depression scores at baseline and a favourable HRQoL outcome at follow up. Conclusion. This multidisciplinary rehabilitation programme, using a non-pharmacological cognitive approach, seemed to yield a better outcome concerning HRQoL measures in younger subjects with higher depression scores at baseline. This information is important for clinics when tailoring a multidisciplinary rehabilitation programme for patients with musculoskeletal chronic pain. Copyright © 2010 John Wiley & Sons, Ltd.

- OBJECTIVE: To study the rate of common comorbidities and cardiovascular disease in patients with ankylosing spondylitis (AS) compared with the general population seeking health care.METHODS: This cohort study included 935 subjects (67% men) ages ≥20 years diagnosed with AS and the adult background population in Southern Sweden. During 2004 to 2007 we recorded the occurrence of physicians' diagnostic codes for a select number of comorbidities commonly associated with AS and cardiovascular disease and risk factors. We obtained standardized morbidity-rate ratios (SMRs) by dividing the observed morbidity rate in AS patients by the expected rate based on the corresponding rate of the disease in the general population of the county seeking health care.RESULTS: The highest SMRs were found for uveitis (34.35, 95% confidence interval [95% CI] 28.55-40.98) and inflammatory bowel disease (9.28, 95% CI 7.07-11.97). Also, we found increased SMRs for ischemic heart diseases (2.20, 95% CI 1.77-2.70), hypertension (1.98, 95% CI 1.72-2.28), and diabetes mellitus (1.41, 95% CI 1.10-1.78). Furthermore, the SMRs for psoriasis, osteoporosis, and atrioventricular blocks were also statistically significantly elevated.CONCLUSION: Inflammatory diseases affecting the eye and the digestive system were the most notable comorbidities in AS patients, but the rate for cardiovascular disease was also high. Using comprehensive longitudinal population-based register data is a promising tool to evaluate the excess consultation rate and total burden of rheumatic disease on patients and society.

Cystatin C influences the autoimmune but not inflammatory response to cartilage type II collagen leading to chronic arthritis development

- INTRODUCTION: Collagen-induced arthritis (CIA) is a mouse model for rheumatoid arthritis (RA) and is induced after immunization with type II collagen (CII). CIA, like RA, is an autoimmune disease leading to destruction of cartilage and joints, and both the priming and inflammatory phases have been suggested to be dependent on proteases. In particular, the cysteine proteases have been proposed to be detrimental to the arthritic process and even immunomodulatory. A natural inhibitor of cysteine proteases is cystatin C. METHODS: Cystatin C-deficient, sufficient and heterozygous mice were tested for onset, incidence and severity of CIA. The effect of cystatin C-deficiency was further dissected by testing the inflammatory effector phase of CIA; that is, collagen antibody-induced arthritis model and priming phase, that is, T cell response both in vivo and in vitro. In addition, in order to determine the importance of T cells and antigen-presenting cells (APCs), these cell populations were separated and in vitro T cell responses determined in a mixed co-culture system. Finally, flow cytometry was used in order to further characterize cell populations in cystatin C-deficient mice. RESULTS: Here, we show that mice lacking cystatin C, develop arthritis at a higher incidence and an earlier onset than wild-type controls. Interestingly, when the inflammatory phase of CIA was examined independently from immune priming then cystatin C-deficiency did not enhance the arthritis profile. However, in line with the enhanced CIA, there was an increased T cell and B cell response as delayed-type hypersensitivity reaction and anti-CII antibody titers were elevated in the cystatin C-deficient mice after immunization. In addition, the ex vivo naive APCs from cystatin C-deficient mice had a greater capacity to stimulate T cells. Interestingly, dendritic cells had a more activated phenotype in naive cystatin C-deficient mice. CONCLUSIONS: The lack of cystatin C enhances CIA and primarily affects in vivo priming of the immune system. Although the mechanism of this is still unknown, we show evidence for a more activated APC compartment, which would elevate the autoimmune response towards CII, thus resulting in an enhanced development of chronic arthritis.

- We have addressed the importance of B cell tolerance to collagen type II, a matrix protein, which is a target in rheumatoid arthritis (RA) and its mouse models. We generated a germline-encoded anti-collagen type II (CII) IgH replacement anti-C1 B cell mouse strain (ACB) to investigate how B cell tolerance to CII, a matrix protein, is subverted and to further understand pathogenesis of RA. Phenotypic analysis revealed that CII-specific B cells were surprisingly neither deleted nor anergized. Instead, they were readily detected in all lymphoid organs. Spontaneously produced autoantibodies could bind directly to cartilage surface without detectable pathology. However, exaggerated arthritis was seen after injection of anti-CII Abs specific for other epitopes. In addition, Abs from CII-specific hybridomas generated from ACB mice induced arthritis. Interestingly, IgH/L chain sequence data in B cell hybridomas revealed a lack of somatic mutations in autoreactive B cells. The ACB model provides the first possibility, to our knowledge, to study B cell tolerance to a matrix protein, and the observations made in the study could not be predicted from previous models. B cell-reactive epitopes on CII are largely shared between human RA and rodent CII-induced arthritis; this study, therefore, has important implications for further understanding of pathological processes in autoimmune diseases like RA.

Tidskriftsartikel (refereegranskat)abstract
- Background: Few studies have investigated the subsequent rate of hospital and outpatient clinic utilization in those who receive continuing care and have documented frequent usage over one year. Such knowledge may be helpful in identifying those who would benefit from preventive interventions. The aim of this study was to investigate and compare the subsequent rate of hospital and outpatient clinic utilization among older people with 0, 1, 2, 3 or more hospital stays in the first year following the initiation of continuing care. A further aim was to compare these groups regarding demographic data, health complaints, functional and cognitive ability, informal care and mortality.Methods: A total of 1079 people, aged 65 years or older, who received a decision regarding the initiation of continuing care during the years 2001, 2002 or 2003 were investigated. Four groups were created based on whether they had 0, 1, 2 or ≥ 3 hospital stays in the first year following the initiation of continuing care and were investigated regarding the rate of hospital and outpatient clinic utilization in the subsequent 3-5 years.Results: Fifty seven percent of the sample had no hospital stay during the first year following the initiation of continuing care, 20% had 1 stay, 10% had 2 stays and 13% had three or more hospital stays (range: 3-13). Those with ≥ 3 hospital stays in the first year continued to have the significantly highest rate of hospital and outpatient care utilization in the subsequent years. This group accounted for 57% of hospital stays in the first year, 27% in the second year and 18% in the third year. In this group the risk of having ≥ 3 hospital stays in the second year was 27% and 12% in the third year.Conclusions: There is a clear need for interventions targeted on prevention of frequent hospital and outpatient clinic utilization among those who are high users of hospital care in the first year after the initiation of continuing care. Perhaps an increased availability of medically skilled staff in the day to day care of these people in the municipalities could prevent frequent hospital and outpatient clinic utilization, especially hospital readmissions. © 2011 Condelius et al; licensee BioMed Central Ltd.
