Biologic drugs (e.g. anti-tumor necrosis factors) are effective treatments for multiple chronic inflammatory diseases including rheumatoid arthritis, axial spondyloarthritis, and psoriatic arthritis. Administration of biologic drugs is usually via subcutaneous self-injection, which provides many patient benefits compared to infusions including increased flexibility, reduced costs, and reduced caregiver burden. However, it is also associated with challenges such as needle phobia, patient treatment misconceptions and incorrect drug administration, and can be impacted by dexterity problems. Evidence suggests these problems, along with other drug administration challenges (e.g. patient forgetfulness, busy lifestyles, and polypharmacy), can reduce patient adherence to treatment. To combat these challenges, patient feedback has been used to develop a range of self-injection devices, including pre-filled syringes, pre-filled pens, and electronic injection devices. Providing different devices for drug administration gives patients the opportunity to choose a device that addresses the challenges they face as an individual. Research suggests involving patients in medical device development, providing patients with a choice of devices and enrolling individuals in patient support programs can empower patients to take control of their treatment journey. By providing a portfolio of self-injection devices, designed based on patient needs, patient experience will improve, potentially improving adherence and hence, long-term treatment outcomes.

BACKGROUND: The association between chronically elevated cortisol, as measured by hair cortisol concentration (HCC), and dietary intake among children has generally not been explored. Moreover, it is unknown whether there is an association between parental HCC and dietary intake among their children.

OBJECTIVE: To examine associations between HCC and dietary intake among children, and to explore the association between parental HCC and dietary intake among their children.

METHODS: We conducted a cross-sectional study based on 296 children predisposed to overweight and obesity who participated in the Healthy Start study. Multiple Linear regression analyses were conducted to assess the association between HCC and total energy intake, macronutrients, fruit and vegetables, added sugar, sugar-sweetened beverages (SSB), and a diet quality index (DQI).

RESULTS: Among the children, we found that higher HCC was associated with a lower consumption of dietary fat (β: -0.7 g/day [95% CI: -1.3, -0.0] per 100 pg/mg HCC). We found no statistically significant association between HCC and intake of total energy, protein, carbohydrate, fruit and vegetables, added sugar, SSB or DQI. We found no association between parental HCC and intake of total energy, added sugar, selected food groups or DQI among their children. However, stratified analyses showed that paternal HCC was associated with a borderline significant lower total energy intake and significantly lower protein intake, but only among daughters (adjusted β: -42 kcal/day [95% CI: -85, 0] and -2.6 g/day [95% CI: -4.4, -0.8] per 100 pg/mg HCC, respectively).

CONCLUSION: Among children, chronic stress as measured by HCC may be associated with a lower fat consumption, and paternal HCC may be associated with a lower intake of energy and protein among their daughters. However, the associations observed were weak, and any clinical relevance of these findings remains questionable.

OBJECTIVE: To describe spontaneous changes in time spent physically inactive measured continuously by accelerometry during an 8-week weight loss intervention in overweight/obese individuals with knee osteoarthritis.

METHOD: This study was designed as an observational cohort study including individuals with concomitant overweight/obesity and symptomatic knee osteoarthritis from an osteoarthritis outpatient clinic. Participants completed an 8-week dietary intervention previously shown to induce substantial weight loss. The main outcome was accelerometer-based measurement of physical inactivity for 24 hours daily during the 8-week intervention period presented as change in the average daily time spent inactive (sitting, reclined or sleeping) from one week prior to intervention to the last week of the intervention.

RESULTS: A total of 124 participants completed the dietary intervention and had valid accelerometer recordings. The mean weight loss was 12.7 kg [95% CI -13.2 to -12.1; P<.0001] after 8 weeks corresponding to a decrease in BMI of 4.3 kg/m2 [95%CI -4.5 to -4.2; P<.0001]. Significant improvements in osteoarthritis symptoms (assessed by the Knee Injury and Osteoarthritis Outcome Score) was found across all subscales; for KOOS pain an improvement of 12.8 points [95% CI, 10.6 to 15.0; P<.0001] was observed. No statistically significant change occurred in the average daily time spent inactive from baseline to follow-up (mean change: 8.8 minutes/day [95% CI, -12.1 to 29.7]; P=0.41).

CONCLUSION: Physical inactivity remains stable despite a clinically significant weight loss and improvements in knee osteoarthritis symptoms. Change in inactivity does not seem to occur spontaneously, suggesting that focused efforts to reduce inactive behaviors are needed. This article is protected by copyright. All rights reserved.

Attribution of weight regain to emotional reasons amongst European adults with overweight and obesity who regained weight following a weight loss attempt

Sainsbury, K., Evans, E. H., Pedersen, S., Marques, M. M., Teixeira, P. J., Lähteenmäki, L., Stubbs, R. J., Heitmann, B. L. & Sniehotta, F. F., apr. 2019, I : Eating and Weight Disorders. 24, 2, s. 351-361 11 s.

PURPOSE: Despite the wide availability of effective weight loss programmes, maintenance of weight loss remains challenging. Difficulties in emotion regulation are associated with binge eating and may represent one barrier to long-term intervention effectiveness in obesity. The purpose of this study was to determine the relationship between emotion regulation difficulties and the extent of weight regain in a sample of adults who had lost, and then regained, weight, and to examine the characteristics associated with emotional difficulties.

METHODS: 2000 adults from three European countries (UK, Portugal, and Denmark) completed an online survey assessing self-reported weight loss and regain following their most recent weight loss attempt. They also completed a binge eating disorder screening questionnaire and, if they had regained weight, were asked if they attributed it to any emotional factors (a proxy for emotion regulation difficulties). Spearman's correlations and logistic regression were used to assess the associations between emotion regulation, weight regain, and strategy use.

RESULTS: Emotion regulation difficulties were associated with greater weight regain (N = 1594 who lost and regained weight). Attribution to emotional reasons was associated with younger age, female gender, loss of control and binge eating, lower perceptions of success at maintenance, using more dietary and self-regulatory strategies in weight loss, and fewer dietary strategies in maintenance.

CONCLUSIONS: Weight-related emotion regulation difficulties are common amongst regainers and are associated with regaining more weight. Affected individuals are already making frequent use of behavioural strategies during weight loss, but do not apply these consistently beyond active attempts. Simply encouraging the use of more numerous strategies, without concurrently teaching emotion regulation skills, may not be an effective means to improving weight outcomes in this group.

LEVEL OF EVIDENCE: Level V, descriptive (cross-sectional) study.

Hansen, M. S., Becerra, L., Dahl, J. B., Borsook, D., Mårtensson, J., Christensen, A., Nybing, J. D., Havsteen, I., Boesen, M. & Asghar, M. S., 10 jan. 2019, I : Brain structure & function.

Central sensitization is a condition in which there is an abnormal responsiveness to nociceptive stimuli. As such, the process may contribute to the development and maintenance of pain. Factors influencing the propensity for development of central sensitization have been a subject of intense debate and remain elusive. Injury-induced secondary hyperalgesia can be elicited by experimental pain models in humans, and is believed to be a result of central sensitization. Secondary hyperalgesia may thus reflect the individual level of central sensitization. The objective of this study was to investigate possible associations between increasing size of secondary hyperalgesia area and brain connectivity in known resting-state networks. We recruited 121 healthy participants (male, age 22, SD 3.35) who underwent resting-state functional magnetic resonance imaging. Prior to the scan session, areas of secondary hyperalgesia following brief thermal sensitization (3 min. 45 °C heat stimulation) were evaluated in all participants. 115 participants were included in the final analysis. We found a positive correlation (increasing connectivity) with increasing area of secondary hyperalgesia in the sensorimotor- and default mode networks. We also observed a negative correlation (decreasing connectivity) with increasing secondary hyperalgesia area in the sensorimotor-, fronto-parietal-, and default mode networks. Our findings indicate that increasing area of secondary hyperalgesia is associated with increasing and decreasing connectivity in multiple networks, suggesting that differences in the propensity for central sensitization, assessed as secondary hyperalgesia areas, may be expressed as differences in the resting-state central neuronal activity.

Calcium and vitamin D supplementation and/or periodontal therapy in the treatment of periodontitis among Brazilian pregnant women: protocol of a feasibility randomised controlled trial (the IMPROVE trial)

Cocate, P. G., Kac, G., Heitmann, B. L., Nadanovsky, P., da Veiga Soares Carvalho, M. C., Benaim, C., Schlüssel, M. M., de Castro, M. B. T., Alves-Santos, N. H., Baptista, A. F., Holick, M. F., Mokhtar, R. R., Bomfim, A. R. & Adegboye, A. R. A., 2019, I : Pilot and Feasibility Studies. 5, s. 38

Background: Periodontitis is a common oral inflammation, which is a risk factor for adverse pregnancy outcomes. Intakes of vitamin D and calcium are inversely associated with occurrence and progression of periodontitis. This study aims to assess the feasibility of a multi-component intervention, including provision of milk powder supplemented with calcium and vitamin D and periodontal therapy (PT), for improving maternal periodontal health and metabolic and inflammatory profiles of low-income Brazilian pregnant women with periodontitis.

Methods: The IMPROVE trial is a feasibility randomised controlled trial (RCT) with a 2 × 2 factorial design with a parallel process evaluation. Pregnant women with periodontitis, aged 18-40 years and with < 20 gestational weeks (n = 120) were recruited and randomly allocated into four groups: (1) fortified sachet (vitamin D and calcium) and powdered milk plus PT during pregnancy, (2) placebo sachet and powdered milk plus PT during pregnancy, (3) fortified sachet (vitamin D and calcium) and powdered milk plus PT after delivery and (4) placebo sachet and powdered milk plus PT after delivery. Dentists and participants are blinded to fortification. Acceptability of study design, recruitment strategy, random allocation, data collection procedures, recruitment rate, adherence and attrition rate will be evaluated. Data on serum levels of vitamin D, calcium and inflammatory biomarkers; clinical periodontal measurements; anthropometric measurements; and socio-demographic questionnaires are collected at baseline, third trimester and 6-8 weeks postpartum. Qualitative data are collected using focus group, for analysis of favourable factors and barriers related to study adherence.

Discussion: Oral health and mineral/vitamin supplementation are much overlooked in the public prenatal assistance in Brazil and of scarcity of clinical trials addressing these issues in low and middle-income countries,. To fill this gap the present study was designed to assess the feasibility of a RCT on acceptability of a multi-component intervention combining conventional periodontal treatment and consumption of milk fortified with calcium-vitamin D for improving periodontal conditions and maternal metabolic and inflammation status, among Brazilian low-income pregnant women with periodontitis. Thus, we hope that this relatively low-cost and safe multicomponent intervention can help reduce inflammation, improve maternal periodontal health and metabolic profile and consequently prevent negative gestational outcomes.

Can legal restrictions of prenatal exposure to industrial trans-fatty acids reduce risk of childhood hematopoietic neoplasms? A population-based study

Specht, I. O., Huybrechts, I., Frederiksen, P., Steliarova-Foucher, E., Chajes, V. & Heitmann, B. L., feb. 2019, I : European Journal of Clinical Nutrition. 73, 2, s. 311-318 8 s.

BACKGROUND: Causes of most childhood hematopoietic neoplasms are unknown. Early age of occurrence suggests prenatal etiology. Positive associations have been reported between industrially produced trans-fatty acids (iTFAs) and risks of some cancers in adults. iTFAs are pro-inflammatory and adversely affect the beneficial effects of essential fatty acids, the latter is diminishing tumor growth. In 2004 Denmark legislated against the use of iTFA in foodstuffs. Using the entire population, we investigated if the changes in the legislation as a proxy to the reduced exposure to iTFA had affected the incidence of childhood hematopoietic neoplasms.

METHODS: We used a Cox proportional hazard model to compare the hazard of childhood hematopoietic neoplasms among children born before and after the iTFA ban, as a proxy for fetal iTFA exposure. To take the potential secular trend in hematopoietic neoplasms into account, we modeled the variation in cancer risk across birth cohorts by a piecewise linear spline with a knot in 2004, which allowed a comparison of the hazard of childhood hematopoietic neoplasms between the time before and after the iTFA ban.

RESULTS: Among children born in 1988-2008 in Denmark, 720 were diagnosed with hematopoietic neoplasms before the age of 7 years, corresponding to an overall incidence rate of 7.6 per 100 000 person years. The incidence rates increased by 2% per cohort in 1988-2004 (hazard ratio: 1.02 [1.01; 1.04]) and in 2004-2008 (hazard ratio: 1.02 [0.95; 1.11]).

CONCLUSIONS: No apparent benefit of the iTFA legislation in reducing childhood hematopoietic neoplasms was observed on population basis. Individual-level data are needed to investigate any possible associations between biomarkers of iTFA intake and risk of childhood hematopoietic neoplasms.

Objectives: A cohort of routine care RA patients in sustained remission had biological DMARD (bDMARDs) tapered according to a treatment guideline. We studied: the proportion of patients whose bDMARD could be successfully tapered or discontinued; unwanted consequences of tapering/discontinuation; and potential baseline predictors of successful tapering and discontinuation.

Methods: One-hundred-and-forty-three patients (91% receiving TNF inhibitor and 9% a non-TNF inhibitor) with sustained disease activity score (DAS28-CRP)⩽2.6 and no radiographic progression the previous year were included. bDMARD was reduced to two-thirds of standard dose at baseline, half after 16 weeks, and discontinued after 32 weeks. Patients who flared (defined as either DAS28-CRP ⩾ 2.6 and ΔDAS28-CRP ⩾ 1.2 from baseline, or erosive progression on X-ray and/or MRI) stopped tapering and were escalated to the previous dose level.

Results: One-hundred-and-forty-one patients completed 2-year follow-up. At 2 years, 87 patients (62%) had successfully tapered bDMARDs, with 26 (18%) receiving two-thirds of standard dose, 39 (28%) half dose and 22 (16%) having discontinued; and 54 patients (38%) were receiving full dose. ΔDAS28-CRP0-2yrs was 0.1((-0.2)-0.4) (median (interquartile range)) and mean ΔTotal-Sharp-Score0-2yrs was 0.01(1.15)(mean(s.d.)). Radiographic progression was observed in nine patients (7%). Successful tapering was independently predicted by: ⩽1 previous bDMARD, male gender, low baseline MRI combined inflammation score or combined damage score. Negative IgM-RF predicted successful discontinuation.

Conclusion: By implementing a clinical guideline, 62% of RA patients in sustained remission in routine care were successfully tapered, including 16% successfully discontinued at 2 years. Radiographic progression was rare. Maximum one bDMARDs, male gender, and low baseline MRI combined inflammation and combined damage scores were independent predictors for successful tapering.

Visceral adipose tissue is harmful to metabolic health. Exercise training reduces visceral adipose tissue mass, but the underlying mechanisms are not known. Interleukin-6 (IL-6) stimulates lipolysis and is released from skeletal muscle during exercise. We hypothesized that exercise-induced reductions in visceral adipose tissue mass are mediated by IL-6. In this randomized placebo-controlled trial, we assigned abdominally obese adults to tocilizumab (IL-6 receptor antibody) or placebo during a 12-week intervention with either bicycle exercise or no exercise. While exercise reduced visceral adipose tissue mass, this effect of exercise was abolished in the presence of IL-6 blockade. Changes in body weight and total adipose tissue mass showed similar tendencies, whereas lean body mass did not differ between groups. Also, IL-6 blockade increased cholesterol levels, an effect not reversed by exercise. Thus, IL-6 is required for exercise to reduce visceral adipose tissue mass and emphasizes a potentially important metabolic consequence of IL-6 blockade.

OBJECTIVES: The aim of this systematic review was to inform the update of European League Against Rheumatism (EULAR) Recommendations for the management of Behçet's syndrome (BS), on the evidence for the treatment of skin, mucosa and joint involvement of BS.

METHODS: A systematic literature search, data extraction, statistical analyses and assessment of the quality of evidence were performed according to a pre-specified protocol using the PRISMA guidelines. Studies that assessed the efficacy of an intervention in comparison to an active comparator or placebo for oral ulcers, genital ulcers, papulopustular lesions, nodular lesions or arthritis were included. Where possible, risk ratios were calculated for binary outcomes and mean difference for continuous outcomes.

RESULTS: Among the 3927 references that were screened, 37 were included in the analyses. Twenty-seven of these assessed mucocutaneous and 17 assessed joint involvement. Twenty-one of these studies were randomised controlled trials (RCTs). RCTs with colchicine, azathioprine, interferon-alpha, thalidomide, etanercept and apremilast showed beneficial results with some differences according to lesion type and gender. These agents were generally well tolerated with few adverse events causing withdrawal from the study.

CONCLUSIONS: RCTs comprised more than a half (21/37, 57%) of the sources included in the evidence synthesis related to skin, mucosa and joint involvement applicable for the EULAR Recommendations for the management of BS. Differences in the outcome measures that were used across the included studies often made it difficult to combine and compare the results.

Night work and sick leave during pregnancy: a national register-based within-worker cohort study

Hammer, P. E. C., Garde, A. H., Begtrup, L. M., Flachs, E. M., Hansen, J., Hansen, Å. M., Hougaard, K. S., Kolstad, H. A., Larsen, A. D., Pinborg, A. B., Specht, I. O. & Bonde, J. P., mar. 2019, I : Occupational and Environmental Medicine. 76, 3, s. 163-168 6 s.

OBJECTIVE: The aim of our study was to investigate the acute effect of night work during pregnancy on the risk of calling in sick the following day using register-based information and the workers as their own controls.

METHODS: Using the payroll-based national Danish Working Hour Database, including all public hospital employees in Denmark, we identified 9799 pregnant women with ≥1 day shift and ≥1 night shift and ≥1 day of sick leave during the first 32 pregnancy weeks from January 2007 to December 2013. We performed fixed effects logistic regression, that is, within-worker comparisons, of the risk of sick leave of any duration starting within 24 hours after night shifts of different length versus day shifts.

RESULTS: Most of the participants were nurses (64%) or physicians (16%). We found an increased relative risk of sick leave following night shifts compared with day shifts during all pregnancy trimesters. The risk was highest for night shifts lasting >12 hours (OR 1.37, 95% CI 1.15 to 1.63 for nurses; OR 1.87, 95% CI 1.69 to 2.08 for physicians) and among women aged >35 years (OR 1.42, 95% CI 1.24 to 1.63).

CONCLUSION: Among Danish public hospital employees night shifts during pregnancy, especially shifts longer than 12 hours, increased the risk of calling in sick the following day independent of personal factors and time-invariant confounders in all pregnancy trimesters.

Opioid-Induced Reductions in Gait Variability in Healthy Volunteers and Individuals with Knee Osteoarthritis

Henriksen, M., Alkjær, T., Raffalt, P. C., Jørgensen, L., Bartholdy, C., Hansen, S. H. & Bliddal, H., 12 jan. 2019, I : Pain medicine (Malden, Mass.).

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningpeer review

Objective: To investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients.

Design: Experimental, randomized, double-blinded, crossover study of inert placebo (calcium tablets), 50 mg of tapentadol, and 100 mg of tramadol.

Setting: Laboratory setting.

Subjects: Healthy volunteers and knee osteoarthritis patients.

Methods: At three visits, separated by seven days, one tablet was administered per visit according to the randomization code. At each visit, a baseline measurement was done before tablet administration, after which hourly measurements were performed for six hours, yielding a total of seven measurements per visit. Gait variability was measured by three-dimensional gait analysis, recorded during six minutes of continuous treadmill walking at self-selected speed. One hundred seventy gait cycles were identified from detection of clear events of the knee joint angle trajectories. Gait variability was assessed as average standard deviations over a gait cycle of the sacrum displacements and accelerations; sagittal plane ankle, knee, and hip joint angles; step widths; and stride times.

Results: Twenty-four opioid-naïve and neurologically intact participants (12 healthy volunteers and 12 knee osteoarthritis patients) were included and completed the experiment. Tapentadol reduced the variability of sacrum displacements and accelerations compared with placebo and tramadol. There were no differences between experimental conditions regarding the variability in lower-extremity joint angle variability, step widths, or stride times.

Conclusions: In opioid-naïve and neurologically intact individuals, tapentadol seems to reduce movement variability during treadmill walking, compared with placebo and tramadol. This can be interpreted as a loss of adaptability that might increase the risk of falling if the system is perturbed.

OBJECTIVE: To examine the reporting completeness of exercise-based interventions for knee osteoarthritis (OA) in studies that form the basis of current clinical guidelines, and examine if the clinical benefit (pain and disability) from exercise is associated with the intervention reporting completeness.

DESIGN: Review of clinical OA guidelines METHODS: We searched MEDLINE and EMBASE for guidelines published between 2006 and 2016 including recommendations about exercise for knee OA. The studies used to inform a recommendation were reviewed for exercise reporting completeness. Reporting completeness was evaluated using a 12-item checklist; a combination of the Template for Intervention Description and Replication (TIDieR) and Consensus on Exercise Reporting Template (CERT). Each item was scored 'YES' or 'NO' and summarized as a proportion of interventions with complete descriptions and each intervention's completeness was summarized as the percentage of completely described items. The association between intervention description completeness score and clinical benefits was analyzed with a multilevel meta-regression.

RESULTS: From 10 clinical guidelines, we identified 103 original studies of which 100 were retrievable (including 133 interventions with 6,926 patients). No interventions were completely described on all 12 items (median 33% of items complete; range 17-75%). The meta-regression analysis indicated that poorer reporting was associated with greater effects on pain and no association with effects on disability.

CONCLUSION: The inadequate description of recommended interventions for knee OA is a serious problem that precludes replication of effective interventions in clinical practice. By consequence, the relevance and usability of clinical guideline documents and original study reports are diminished.

Prevalence of psoriatic arthritis in patients with psoriasis: A systematic review and meta-analysis of observational and clinical studies

Alinaghi, F., Calov, M., Kristensen, L. E., Gladman, D. D., Coates, L. C., Jullien, D., Gottlieb, A. B., Gisondi, P., Wu, J. J., Thyssen, J. P. & Egeberg, A., jan. 2019, I : Journal of the American Academy of Dermatology. 80, 1, s. 251-265.e19

BACKGROUND: Wide-ranging prevalence estimates of psoriatic arthritis (PsA) in patients with psoriasis have been reported.

OBJECTIVES: To assess the prevalence and incidence of PsA in patients with psoriasis.

METHODS: Two authors independently searched 3 databases for studies reporting on the prevalence or incidence of PsA in patients with psoriasis. A proportion meta-analysis was performed to calculate the pooled proportion estimates of PsA in patients with psoriasis.

RESULTS: A total of 266 studies examining 976,408 patients with psoriasis were included. Overall, the pooled proportion (95% confidence interval [CI]) of PsA among patients with psoriasis was 19.7% (95% CI, 18.5%-20.9%). In children and adolescents (<18 years of age), the pooled prevalence was 3.3% (95% CI, 2.1%-4.9%). The PsA prevalence was 22.7% (95% CI, 20.6%-25.0%) in European patients with psoriasis, 21.5% (95% CI, 15.4%-28.2%) in South American patients with psoriasis, 19.5% (95% CI, 17.1%-22.1%) in North American patients with psoriasis, 15.5% (95% CI, 0.009%-51.5%) in African patients with psoriasis, and 14.0% (95% CI, 95% CI, 11.7%-16.3%) in Asian patients with psoriasis. The prevalence of PsA was 23.8% (95% CI, 20.1%-27.6%) in studies in which the Classification Criteria for Psoriatic Arthritis were applied. The incidence of PsA among patients with psoriasis ranged from 0.27 to 2.7 per 100 person-years.

LIMITATIONS: Between-study heterogeneity may have affected the estimates.

CONCLUSIONS: We found that 1 in 4 patients with psoriasis have PsA. With the growing recognition of the Classification Criteria for Psoriatic Arthritis, more homogenous and comparable prevalence estimates are expected to be reported.

Objectives: To investigate temporal trends in the incidence and prevalence of gout in the adult Danish population.

Methods: Using the nationwide Danish National Patient Registry, we calculated the number of incident gout patients (per 100 000 person-years) within each 1 year period from 1995 to 2015 and the prevalence of gout in 2000 and 2015. Further, we calculated age- and gender-specific incidence rates of gout from 1995 to 2015.

Results: We identified a total of 45 685 incident gout patients (72.9% males) with a mean age of 65 years (s.d. 16) at diagnosis. In both genders, an increase in age-standardized incidence rates was observed from 32.3/100 000 (95% CI 30.7, 33.9) in 1995 to 57.5/100 000 (95% CI 55.6, 59.5) in 2015 (P < 0.001). Similar trends were observed for 8950 cases diagnosed in rheumatology departments. We likewise observed an increase in the prevalence of gout from 0.29% (95% CI 0.29, 0.30) in 2000 to 0.68% (95% CI 0.68, 0.69) in 2015.

Conclusions: The annual incidence rate of gout increased by almost 80% in Denmark between 1995 and 2015. The prevalence increased by nearly 130% between 2000 and 2015. Reasons for this are unknown but may include an increase in risk factors (e.g. obesity, diabetes mellitus), longer life expectancy and increased awareness of the disease among patients and/or health professionals.

Several new treatment modalities with different mechanisms of action have been studied in patients with Behçet's syndrome (BS). The aim of the current effort was to update the recommendations in the light of these new data under the auspices of the European League Against Rheumatism (EULAR) Standing Committee for Clinical Affairs. A task force was formed that included BS experts from different specialties including internal medicine, rheumatology, ophthalmology, dermatology, neurology, gastroenterology, oral health medicine and vascular surgery, along with a methodologist, a health professional, two patients and two fellows in charge of the systematic literature search. Research questions were determined using a Delphi approach. EULAR standardised operating procedures was used as the framework. Results of the systematic literature review were presented to the task force during a meeting. The former recommendations were modified or new recommendations were formed after thorough discussions followed by voting. The recommendations on the medical management of mucocutaneous, joint, eye, vascular, neurological and gastrointestinal involvement of BS were modified; five overarching principles and a new recommendation about the surgical management of vascular involvement were added. These updated, evidence-based recommendations are intended to help physicians caring for patients with BS. They also attempt to highlight the shortcomings of the available clinical research with the aim of proposing an agenda for further research priorities.

A core domain set for hidradenitis suppurativa trial outcomes: an international Delphi process

HIdradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC), sep. 2018, I : British Journal of Dermatology. 179, 3, s. 642-650 9 s.

BACKGROUND: There is no consensus on core outcome domains for hidradenitis suppurativa (HS). Heterogeneous outcome measure instruments in clinical trials likely leads to outcome-reporting bias and limits the ability to synthesize evidence.

OBJECTIVES: To achieve global multistakeholder consensus on a core outcome set (COS) of domains regarding what to measure in clinical trials for HS.

METHODS: Six stakeholder groups participated in a Delphi process that included five anonymous e-Delphi rounds and four face-to-face consensus meetings to reach consensus on the final COS. The aim was for a 1 : 1 ratio of patients to healthcare professionals (HCPs).

RESULTS: A total of 41 patients and 52 HCPs from 19 countries in four continents participated in the consensus process, which yielded a final COS that included five domains: pain, physical signs, HS-specific quality of life, global assessment and progression of course. A sixth domain, symptoms, was highly supported by patients and not by HCPs but is recommended for the core domain set.

CONCLUSIONS: Routine adoption of the COS in future HS trials should ensure that core outcomes of importance to both patients and HCPs are collected.

PURPOSE: The purpose of this study was to explore the immediate effects of heavy isometric plantar flexor exercise on sensory output (pain during a functional task and mechanical pain sensitivity) and motor output (plantar flexor torque) in individuals with Achilles tendinopathy.

METHODS: Sixteen subjects with Achilles tendinopathy participated in the study, mean (SD) age 48.6 (8.9) years and Victorian institute assessment-Achilles (VISA-A) score 61.3 (23.0). Sensory testing assessing pain during a functional task, mechanical pain sensitivity and motor output, and plantar flexor peak torque was completed prior to the intervention. All subjects completed a 45-s heavy isometric plantar flexor contraction and were then re-tested using the same sensory and motor tests. Motor output was assessed using isokinetic dynamometry at speeds previously identified as of interest in subjects with Achilles tendinopathy.

RESULTS: Only 9 of the 16 subjects experienced pain during a functional task, self-reported pain was 4.2 (1.9) numerical rating scale (NRS) pre-intervention and 4.9 (3.2) NRS postintervention (n.s.). Mechanical pressure sensitivity was 446.5 (± 248.5) g/mm2 pre-intervention and 411.8 (± 211.8) g/mm2 post-intervention (n.s.). Mean concentric plantar flexor torque at 90 and 225°/s was 47.1 (14.5) and 33.6 (11.6) Nm, respectively, pre-intervention and 53.0 (18.5) and 33.4 (6.6) Nm post-intervention (p = 0.039 and n.s.). Eccentric torque at 90°/s was 98.5 (34.2) Nm preintervention versus 106.0 (41.4) Nm post-intervention (n.s.).

CONCLUSION: In this exploratory study, patients with Achilles tendinopathy had a varied sensory and motor output response to heavy isometric contractions. Using the recommended approach of heavy 45-s isometric contractions did not offer a meaningful acute benefit for sensory or motor output for subjects with Achilles tendinopathy. Based on this study, heavy 45-s isometric contractions cannot be recommended for immediate pain relief or improved motor output for patients with Achilles tendinopathy.

LEVEL OF EVIDENCE: IV, prospective cohort study.
