- Introduction: Inflammatory bowel diseases (IBD), encompassing Crohn's disease and ulcerative colitis, are chronic, inflammatory diseases of the gastrointestinal tract. We have initiated a Danish population-based inception cohort study aiming to investigate the underlying mechanisms for the heterogeneous course of IBD, including need for, and response to, treatment.Methods and analysis: IBD Prognosis Study is a prospective, population-based inception cohort study of unselected, newly diagnosed adult, adolescent and paediatric patients with IBD within the uptake area of Hvidovre University Hospital and Herlev University Hospital, Denmark, which covers approximately 1 050 000 inhabitants (~20% of the Danish population). The diagnosis of IBD will be according to the Porto diagnostic criteria in paediatric and adolescent patients or the Copenhagen diagnostic criteria in adult patients. All patients will be followed prospectively with regular clinical examinations including ileocolonoscopies, MRI of the small intestine, validated patient-reported measures and objective examinations with intestinal ultrasound. In addition, intestinal biopsies from ileocolonoscopies, stool, rectal swabs, saliva samples, swabs of the oral cavity and blood samples will be collected systematically for the analysis of biomarkers, microbiome and genetic profiles. Environmental factors and quality of life will be assessed using questionnaires and, when available, automatic registration of purchase data. The occurrence and course of extraintestinal manifestations will be evaluated by rheumatologists, dermatologists and dentists, and assessed by MR cholangiopancreatography, MR of the spine and sacroiliac joints, ultrasonography of peripheral joints and entheses, clinical oral examination, as well as panoramic radiograph of the jaws. Fibroscans and dual-energy X-ray absorptiometry scans will be performed to monitor occurrence and course of chronic liver diseases, osteopenia and osteoporosis.Ethics and dissemination: This study has been approved by Ethics Committee of the Capital Region of Denmark (approval number: H-20065831). Study results will be disseminated through publication in international scientific journals and presentation at (inter)national conferences.

- PURPOSE: The aim was to explore ophthalmic health care in female patients with Usher Syndrome type I (USH I) over 20 years and to evaluate the relationship between the ophthalmic health care and the health state of the patients from a health perspective. METHODS: A retrospective study of records from ophthalmology departments (OD) and low vision clinics (LVC) from 1985 to 2004. Assessment of the reports was performed based on the International Classification of Functioning, Disability and Health (ICF). Findings were analysed by manifest content analysis with ICF as a framework and using four themes: health care system, procedure examinations, patient's functioning and disability and procedure actions. RESULTS: The records of nine female patients (aged 25-39 years, 1985) with USH I were selected from the national database of USH. A great number of notes were collected (OD 344 and LVC 566). Procedure examinations were exclusively oriented towards body structure and function. All patients showed aggravated visual impairment over and above the hearing and vestibular impairment. Procedure actions were oriented towards environmental factors. No correlation was found between procedures performed and patient's experience of disability. CONCLUSIONS: The high degree of resource allocation was not correlated to the patients' impairment. The study indicates that the ophthalmic health care was characterised by inefficiency. This conclusion is very serious because patients very likely face severe disability and emotional difficulties. ICF is ought to be incorporated in ophthalmic health care strategy to improve the health care.

Evaluation of PET tracers [11C]D-deprenyl, [11C]L-dideuteriumdeprenyl and [18F]FDG for Visualization of Acute Inflammation in a Rat Model of Pain - Preliminary Findings.
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Purpose: Positron emission tomography with the radioligand [11C]D-deprenyl has shown an increased signal at the location of pain in patients with ankle sprains, rheumatoid arthritis and chronic whiplash injury, but the mechanism of this tracer uptake and its exact binding site in inflammation or tissue injury is still unclear. The aim of this study was to further evaluate [11C]D-deprenyl´s usefulness as a marker of acute inflammation.Methods: An animal PET/CT study was performed three days after the induction of a rat model of inflammatory or surgical pain. Fourteen adult male Sprague-Dawley rats and three tracers [11C]D-deprenyl, [11C]L-dideuterumdeprenyl and [18F]fluorodeoxyglucose were used. Results: No [11C]D-deprenyl accumulation was seen in a rat model of musculoskeletal pain. In the rat model of inflammatory pain all three ligands were shown to visualize the inflamed ankle joint with much lower uptake in the control ankle joint. The uptake was largest with [11C]D-deprenyl and [11C]L- dideuteriumdeprenyl, where approximately 1 % of the injected dose could be found in the affected ankle joint during the first minutes, whereas the uptake of [18F]FDG was approximately 0.5 % of the injected dose. However, the ratio of uptake of the injected ankle joint versus the control ankle joint was much higher for [18F]FDG (around 10 fold increase) than for the two deprenyl enantiomers (2 – 3 fold increase). The uptake pattern of [11C]D-deprenyl and [11C]L-dideuteriumdeprenyl did not show signs of specific binding or irreversible trapping.Conclusions: Contrary to our expectations, of the three tracers only [18F]FDG may be used as markers of peripheral inflammation in a rat model of inflammatory pain. However, as a high site-specificity is required, [11C]D-deprenyl and [11C]L-dideyteriumdeprenyl deserve further exploration regarding sensitivity, specificity and uptake mechanisms in human pain syndromes.

Konferensbidrag (refereegranskat)abstract
- This study focuses on production flow for publishing in generic digital newsprint editions, such as e-paper, PDAs or on-line editions, by analyzing and mapping existing production workflow at three Swedish newspaper publishing companies covering the most common organizational types in the newspaper publishing industry today. Most newspaper publishing companies produce a range of electronic editions, all part of the digital newsprint family. In general, there exists two types of organizational production workflows - the integrated multiple channel workflow, and the separated, where the printed and the electronic workflows are detached, sometimes in totally separate organizations. Using scenarios, the aim is to propose a model for the production workflow of the electronic paper editions in newspaper publishing. The results indicate several possibilities for automation in the workflow. Furthermore, the study points out stages as challenges in the workflow where changes have to be done in order to introduce epaper as a publishing channel for news publishing. We will as an introduction, along with the workflow scenarios in this paper, also present a brief overview of the existing techniques for displaying content on electronic paper terminals.

- Rheumatoid arthritis-associated joint pain is frequently observed independent of disease activity, suggesting unidentified pain mechanisms. We demonstrate that antibodies binding to cartilage, specific for collagen type II (CII) or cartilage oligomeric matrix protein (COMP), elicit mechanical hypersensitivity in mice, uncoupled from visual, histological and molecular indications of inflammation. Cartilage antibody-induced pain-like behavior does not depend on complement activation or joint inflammation, but instead on tissue antigen recognition and local immune complex (IC) formation. smFISH and IHC suggest that neuronal Fcgr1 and Fcgr2b mRNA are transported to peripheral ends of primary afferents. CII-ICs directly activate cultured WT but not FcRγ chain-deficient DRG neurons. In line with this observation, CII-IC does not induce mechanical hypersensitivity in FcRγ chain-deficient mice. Furthermore, injection of CII antibodies does not generate pain-like behavior in FcRγ chain-deficient mice or mice lacking activating FcγRs in neurons. In summary, this study defines functional coupling between autoantibodies and pain transmission that may facilitate the development of new disease-relevant pain therapeutics.

- Nordic ophthalmologists and vision scientists are active in many fields of eye research. This is most evident at the biannual Nordic Congress of Ophthalmology, most recently held in Malmö in June 2004. The authors here review some of the research in vision and ophthalmology presented at this meeting or published recently by Nordic scientists. This paper does not represent a comprehensive review of all Nordic research in the field, but attempts to give an overview of some of the activities underway in eye research in this part of the world.

Tidskriftsartikel (refereegranskat)abstract
- Background: The prerequisite for obtaining sickness benefit is reduced work ability for medical reasons in combination with work demands which cannot be adjusted accordingly. The aim of this study was to investigate if low levels of adjustment latitude, defined as the possibility to temporarily adjust work demands in case of ill health, influence sickness absence. Methods: A prospective cohort study of 1420 employees (47% participation, aged 19-68; 56% women) was conducted at six Swedish workplaces. Exposure to two general and nine specific types of adjustment latitude was ascertained at baseline. Outcome was defined as the first new employer-reported sick-leave spell during a follow-up of 3-12 months. Hazard ratios (HR) of sick leave, with 95% confidence intervals (CI), were estimated by Cox proportional hazards regression. Results: The incidence of sickness absence was 2.85/1000 person-days. The self-reported reasons for sick leave were mainly minor complaints such as colds, influenzas and headaches. Employees lacking adjustment latitude had an adjusted HR of sickness absence of 1.51 (95% CI 1.08-2.11). Among specific adjustment latitude types, those not having the possibility to work from home generated an HR of 1.86 (95% CI 1.31-2.64). The effects of lack of adjustment latitude were similar for men and women but seemed to vary between different occupations. Conclusion: A low level of adjustment latitude at work is a risk factor for sickness absence.
