Background: Psoriasis (PsO) and psoriatic arthritis (PsA) are chronic diseases that affect patients' quality of life. The purpose of the present study was to develop a pilot outcome-based, patient-centric management model for PsO and PsA.

Methods: The non-interventional IMPROVE (Incentives for healthcare management based on patient-related outcomes and value) study being conducted in Denmark consists of 5 phases: 1) collecting real-world evidence to estimate treatment patterns and disease burden to the healthcare sector and patients; 2) identifying disease aspects which matter most to patients by use of concept mapping; 3) conducting interviews with healthcare professionals and patient organization involved in a typical PsO or PsA patient journey in order to determine relevant measures to quantify patient-identified outcomes; 4) developing a value-based remuneration model based on outcomes from phases 1-3; and 5) testing the outcome-based model in pre-selected hospitals in Denmark.

Results: Both PsO and PsA are associated with multiple co-morbidities, increased healthcare costs, and loss of earnings. Seven important 'clusters' of disease aspects were identified for both PsO and PsA, including uncertainty about disease progression and treatments, as well as inter-personal relations with healthcare providers. Hospital-based treatment was associated with high treatment costs. Although the outcome-based model could result in strategic behavior by doctors, those involved in defining the best outcome goals consider it unlikely.

Conclusion: The new patient-centric outcome-based management model is expected to support optimal treatment and secure best possible outcomes for patients suffering from PsO or PsA. The practical implication of the present study are that the models developed are expected to increase focus on patient-centered healthcare, and help eliminate some of the inappropriate incentives that exist in activity-based remuneration systems.

Trial registration: Not applicable; data collected from patient registries in Denmark.

Interhospital Transport of Sick Newborns In Denmark

Heiring, C., Zachariassen, G., Christensen, P. S., Kjærgaard, S., Nielsen, H. V., Hansen, T. G., Mortensen, S., Hertel, S. A. & Breindahl, M., 30 mar. 2020, I: Ugeskrift for Laeger. 182, 14A

Interhospital transport of sick newborn infants is dangerous, but the risk of adverse events can be reduced, when transport is being performed by trained neonatal retrieval teams. In this review, we describe the current organisation of neonatal retrieval service in Denmark. The services are based at the neonatal intensive care units of the four university hospitals. Improved cooperation and harmonisation of operations between the teams is needed, as this is a prerequisite for the development of a national clinical consensus guideline and national quality metrics enabling benchmarking both within Denmark and abroad.

Less Severe Preoperative Synovitis is Associated With Higher Self-reported Pain Intensity 12 Months After Total Knee Arthroplasty-An Exploratory Prospective Observational Study

Petersen, K. K., Arendt-Nielsen, L., Vela, J., Skou, S. T., Eld, M., Al-Mashkur, N. M., Boesen, M., Riis, R. G. C. & Simonsen, O., jan. 2020, I: The Clinical journal of pain. 36, 1, s. 34-40 7 s.

OBJECTIVES: Synovitis is one of the possible pain generators in osteoarthritis (OA) and is associated with upregulation of proinflammatory cytokines, which can lead to worsening of the postoperative pain. This exploratory study aimed to investigate the association between perioperative synovitis and self-reported pain 12 months after total knee arthroplasty (TKA) in patients with OA.

MATERIALS AND METHODS: Twenty-six knee OA patients were included in this analysis. The perioperative volume of synovitis in predefined locations was assessed by contrast-enhanced magnetic resonance imaging (CE-MRI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Perioperative synovitis was assessed histologically from biopsies of the synovium. Highest pain intensity within the last 24 hours (Visual Analog Scale, VAS, 0 to 100) was assessed before and 12 months after TKA. Patients were divided into a low-pain intensity (VAS≤30) and a high-pain intensity (VAS>30) group on the basis of 12 months postoperative VAS.

RESULTS: The high-pain intensity group had significantly lower perioperative contrast-enhanced-synovitis (P=0.025), DCE-synovitis (P<0.04), and a trend toward lower histologically assessed synovitis (P=0.077) compared with the low-pain intensity group. Perioperative synovitis scores were inversely correlated with pain intensity 12 months after TKA (P<0.05), indicating that more severe perioperative synovitis is associated with less severe pain intensity at 12 months.

DISCUSSION: Higher degrees of perioperative synovitis scores are found to be associated with less postoperative pain 12 months after TKA. Further, correlation analysis revealed that less severe perioperative CE-MRI and DCE-MRI synovitis was associated with higher pain intensity 12 months after TKA, suggesting that CE-MRI and DCE-MRI synovitis grades could be used as imaging markers for prediction of chronic postoperative pain after TKA.

Lessons learned about occupation-focused and occupation-based interventions: A synthesis using group concept mapping methodology

Nielsen, K. T., la Cour, K., Christensen, J. R., Pilegaard, M. S., von Bülow, C., Brandt, Å., Peoples, H., Jonsson, H. & Wæhrens, E. E., okt. 2020, I: Scandinavian Journal of Occupational Therapy. 27, 7, s. 481-492 12 s.

Introduction: Occupational therapy (OT) is based on the core assumption that humans are active beings through engagement in occupations. Within OT, occupation is typically used as primary means and/or ends i.e. occupation-focused and/or occupation-based interventions are employed. Studies evaluating such interventions are limited.Objectives: To synthesize experiences about occupation-focused and/or occupation-based interventions. Hence, to identify, organize and prioritize experiences with employing occupation as a core element in OT intervention studies.Methods: Participants were OT PhD students and researchers involved in studies concerning occupation-focused and/or occupation-based interventions. Group Concept Mapping was applied.Results: Based on 133 ideas, a conceptual model emerged encompassing two overall dimensions concerning 'developing interventions' and 'planning intervention studies', respectively. Moreover, ten themes related to one or both dimensions were defined and 94 ideas across clusters had high importance ratings.Conclusion: Synthesis of participants' experiences indicates that 'doing' as agent of change is a core element of OT interventions. Moreover, a multi-level perspective is needed to reach sustainable changes in doing. Group- and peer-support can work as amplifier for change, and flexibility is important during intervention. Such complex interventions need special design and mixed methods in the development, and evaluation of outcome needs to address occupation.

Levels and changes in body mass index decomposed into fat and fat-free mass index: relation to long-term all-cause mortality in the general population

Sørensen, T. I. A., Frederiksen, P. & Heitmann, B. L., okt. 2020, I: International journal of obesity (2005). 44, 10, s. 2092-2100 9 s.

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

BACKGROUND: In the general population, body mass index (BMI = weight (kg)/(height (m))2) shows a U-shaped relation to mortality, which is attributable to a combination of an inverse association with fat-free mass index (FFMI) and a direct association with fat mass index (FMI). However, preceding changes in body composition related to diseases, health behaviors, or social conditions that are also influencing later mortality may confound these associations.

OBJECTIVE: To examine associations of FFMI and FMI, adjusted for preceding changes in FFMI and FMI over a 6 years period, with all-cause mortality in a healthy general population.

METHODS: The study population was a random subset of adult Danes, participating in the Danish MONICA project; 989 men and 962 women, born 1922, 1932, 1942, and 1952, and examined in 1987-88 and 1993-94. They had no known major co-morbidities until start of follow-up in 1993-94, and were followed up for 18 years. Measures included height, weight, and bio-impedance, from which BMI, FFMI, and FMI were calculated, and information on educational level, smoking, alcohol drinking, leisure-time physical activity, which were obtained by questionnaires. We analyzed the relation between body composition and all-cause mortality by Cox proportional hazards model with splines, stratified by birth cohorts, and with adjustment for preceding changes in body composition and for the covariates including gender. We estimated hazard ratios (HR) with 95% confidence intervals (CI) relative to HR = 1.00 at the median values of BMI, FMI, and FFMI.

RESULTS: During 18 years of follow-up, 286 men and 200 women died. BMI showed the well-known U-shaped association with mortality, and FMI was directly and FFMI inversely associated with mortality. Associations were not significantly modified by gender. Preceding changes in BMI, FMI, and FFMI were only weakly and not significantly associated with mortality. Associations for FMI and FFMI were monotonic, but curve-linear with a higher mortality above and below the respective median values of FMI and FFMI: at the 5th percentiles of FMI and FFMI, HRs were 0.80 (CI 0.57-1.13) and 2.01 (1.24-3.27), and at the 95th percentiles, HRs were 2.16 (1.38-3.38) and 0.81 (0.52-1.27), respectively.

CONCLUSIONS: In an apparently healthy general population, a large fat mass and a small fat-free mass are associated with greater risk of early mortality, also after adjusting for preceding changes in body composition, health behaviors, and educational level.

BACKGROUND: Air pollution exposure has been linked to coronary heart disease, although evidence on

PM

2.5

and myocardial infarction (MI) incidence is mixed.

OBJECTIVES: This prospective cohort study aimed to investigate associations between long-term exposure to air pollution and MI incidence, adjusting for road traffic noise.

METHODS: We used data from the nationwide Danish Nurse Cohort on 22,882 female nurses (

, with both overall and fatal incident MI. Associations were explored in three progressively adjusted models: Model 1, adjusted for age and baseline year; Model 2, with further adjustment for potential confounding by lifestyle and cardiovascular disease risk factors; and Model 3, with further adjustment for road traffic noise, modeled as the annual mean of a weighted 24-h average (

RESULTS: Of the 22,882 women, 641 developed MI during a mean follow-up of 18.6 y, 121 (18.9%) of which were fatal. Reported hazard ratios (HRs) were based on interquartile range increases of 5.3, 5.5, 8.1, and

Ambient air pollution has been linked to stroke, but few studies have examined in detail stroke subtypes and confounding by road traffic noise, which was recently associated with stroke. Here we examined the association between long-term exposure to air pollution and incidence of stroke (overall, ischemic, hemorrhagic), adjusting for road traffic noise. In a nationwide Danish Nurse Cohort consisting of 23,423 nurses, recruited in 1993 or 1999, we identified 1,078 incident cases of stroke (944 ischemic and 134 hemorrhagic) up to December 31, 2014, defined as first-ever hospital contact. The full residential address histories since 1970 were obtained for each participant and the annual means of air pollutants (particulate matter with diameter < 2.5 µm and < 10 µm (PM
2.5 and PM
10), nitrogen dioxide (NO
2), nitrogen oxides (NOx)) and road traffic noise were determined using validated models. Time-varying Cox regression models were used to estimate hazard ratios (HR) (95% confidence intervals (CI)) for the associations of one-, three, and 23-year running mean of air pollutants with stroke adjusting for potential confounders and noise. In fully adjusted models, the HRs (95% CI) per interquartile range increase in one-year running mean of PM
2.5 and overall, ischemic, and hemorrhagic stroke were 1.12 (1.01-1.25), 1.13 (1.01-1.26), and 1.07 (0.80-1.44), respectively, and remained unchanged after adjustment for noise. Long-term exposure to ambient PM
2.5 was associated with the risk of stroke independent of road traffic noise.

BACKGROUND/OBJECTIVES: To investigate the associations between indicators of obesity and fat distribution, such as body mass index (BMI), fat mass, and skinfold measures during preschool age, and attained height at school entry.

SUBJECTS/METHODS: The Healthy Start primary intervention study comprised 1100 obesity-prone preschool children from the greater Copenhagen area, with a mean [standard deviation (SD)] age of 4.0 (1.1) years at baseline. Anthropometry was measured by trained health professionals at baseline (preschool age) and follow-up height at school entry was gathered by school nurses. Prospective associations between body fat measures and later attained height were examined using generalized linear models with adjustments for potential confounders.

RESULTS: Greater adiposity at preschool age was directly associated with a higher attained height at follow-up at school-age, when adjusting for confounders. A baseline difference of one BMI unit was associated with a greater attained height of 0.8 cm [(95% confidence interval (CI) 0.5; 1.2]. Furthermore, a difference of 1 mm in the sum of four skinfolds measured at baseline was associated with a greater attained height of 0.1 cm (95% CI 0.03; 0.2) at follow-up. Children with overweight or obesity at baseline attained a significantly higher height of 2.9 (95% CI 1.6; 4.1) cm at follow-up after full adjustment than normal weight children.

CONCLUSIONS: Our results supports that greater adiposity at preschool age is associated with greater tallness. Although a greater height is assumed to be desirable, accelerated growth in childhood may in itself be a risk factor for obesity later in life.

Low-Dose Naltrexone for the Treatment of Fibromyalgia: Investigation of Dose-Response Relationships

Bruun-Plesner, K., Blichfeldt-Eckhardt, M. R., Vaegter, H. B., Lauridsen, J. T., Amris, K. & Toft, P., 1 okt. 2020, I: Pain medicine (Malden, Mass.). 21, 10, s. 2253-2261 9 s.

OBJECTIVE: This study explores dose-response relationships when treating fibromyalgia with low-dose naltrexone.

DESIGN: A single-blinded clinical trial was carried out using the "up-and-down" method.

SUBJECTS: Subjects included women with a diagnosis of fibromyalgia aged 18-60 years who had been referred to treatment at a public pain clinic at a Danish university hospital.

METHODS: The test doses were in the range 0.75-6 mg, and the dosing interval was 0.75 mg. The method was sequential and allowed predicting the dose effective in 50% (ED50) and 95% (ED95) of the subjects when the dose had shifted direction 10 times, and six pairs of "up-and-down" data were available.

RESULTS: A total of 27 subjects were included in the study; two subjects were withdrawn. After inclusion of 25 evaluable subjects, the dose estimates were calculated as 3.88 mg for ED50 and 5.40 mg for ED95. As a secondary outcome, the effects on 10 common fibromyalgia symptoms were evaluated. A high interindividual variation was observed both in the symptom presentation at baseline and in which symptoms were reduced by low-dose naltrexone.

CONCLUSIONS: This study is the first to explore dose-response relationships in the treatment of fibromyalgia with low-dose naltrexone. Future placebo-controlled randomized clinical trials are needed, and according to our findings, 4.5 mg, which has previously been used, seems to be a relevant test dose. We recommend that future studies include additional nonpain fibromyalgia symptoms as outcome measures.
