Abstract
BACKGROUND Bleeding in the pelvis can lead to a circulatory problem. The widely used whole-body computed tomography (WBCT) scan in the context of treatment in the trauma resuscitation unit (TRU) can give an idea of the source of bleeding (arterial vs. venous/osseous); however, the volume determination of an intrapelvic hematoma by volumetric planimetry cannot be used for a quick estimation of the blood loss. Simplified measurement techniques using geometric models should be used to estimate the extent of bleeding complications. OBJECTIVE To determine whether simplified geometric models can be used to quickly and reliably determine intrapelvic hematoma volume in fractures type Tile B/C during emergency room diagnostics or whether the time-consuming planimetric method must always be used. MATERIAL AND METHODS Retrospectively, 42 intrapelvic hemorrhages after pelvic fractures Tile B + C (n = 8:B, 34:C) at two trauma centers in Germany were selected (66% men, 33% women; mean age 42 ± 20 years) and the CT scans obtained during the initial trauma scan were analyzed in more detail. The CT datasets of the included patients with 1-5 mm slice thickness were available for analysis. By area labelling (ROIs) of the hemorrhage areas in the individual slice images, the volume was calculated by CT volumetrically. Comparatively, volumes were calculated using simplified geometric figures (cuboid, ellipsoid, Kothari). A correction factor was determined by calculating the deviation of the volumes of the geometric models from the planimetrically determined hematoma size. RESULTS AND DISCUSSION The median planimetric bleeding volume in the total collective was 1710 ml (10-7152 ml). Relevant pelvic bleeding with a total volume > 100 ml existed in 25 patients. In 42.86% the volume was overestimated in the cuboid model and in 13 cases (30.95%) there was a significant underestimation to the planimetrically measured volume. Thus, we excluded this volume model. In the models ellipsoid and measuring method according to Kothari, an approximation to the planimetrically determined volume could be achieved with a correction factor calculated via a multiple linear regression analysis. The time-saving and approximate quantification of the hematoma volume using a modified ellipsoidal calculation according to Kothari makes it possible to assess the extent of bleeding in the pelvis after trauma if there are signs of a C-problem. This measurement method, as a simple reproducible metric, could be embedded in trauma resuscitation units (TRU) in the future.

Abstract
The coherent dynamics of a quantum mechanical two-level system passing through an anti-crossing of two energy levels can give rise to Landau-Zener-Stückelberg-Majorana (LZSM) interference. LZSM interference spectroscopy has proven to be a fruitful tool to investigate charge noise and charge decoherence in semiconductor quantum dots (QDs). Recently, bilayer graphene has developed as a promising platform to host highly tunable QDs potentially useful for hosting spin and valley qubits. So far, in this system no coherent oscillations have been observed and little is known about charge noise in this material. Here, we report coherent charge oscillations and [Formula: see text] charge decoherence times in a bilayer graphene double QD. The charge decoherence times are measured independently using LZSM interference and photon assisted tunneling. Both techniques yield [Formula: see text] average values in the range of 400-500 ps. The observation of charge coherence allows to study the origin and spectral distribution of charge noise in future experiments.

Abstract
Particle-hole symmetry plays an important role in the characterization of topological phases in solid-state systems1. It is found, for example, in free-fermion systems at half filling and it is closely related to the notion of antiparticles in relativistic field theories2. In the low-energy limit, graphene is a prime example of a gapless particle-hole symmetric system described by an effective Dirac equation3,4 in which topological phases can be understood by studying ways to open a gap by preserving (or breaking) symmetries5,6. An important example is the intrinsic Kane-Mele spin-orbit gap of graphene, which leads to a lifting of the spin-valley degeneracy and renders graphene a topological insulator in a quantum spin Hall phase7 while preserving particle-hole symmetry. Here we show that bilayer graphene allows the realization of electron-hole double quantum dots that exhibit near-perfect particle-hole symmetry, in which transport occurs via the creation and annihilation of single electron-hole pairs with opposite quantum numbers. Moreover, we show that particle-hole symmetric spin and valley textures lead to a protected single-particle spin-valley blockade. The latter will allow robust spin-to-charge and valley-to-charge conversion, which are essential for the operation of spin and valley qubits.

Abstract
AIMS A nationwide diabetic retinopathy (DR) screening program has been established in Denmark since 2013. We aimed to perform an evaluation of adherence to DR screenings and to examine whether non-adherence was correlated to DR progression. METHODS The population consisted of a register-based cohort, who participated in the screening program from 2013 to 2018. We analyzed age, gender, marital status, DR level (International Clinical DR severity scale, none, mild-, moderate-, severe non-proliferative DR (NPDR) and proliferative DR (PDR)), comorbidities and socioeconomic factors. The attendance pattern of patients was grouped as either timely (no delays > 33%), delayed (delays > 33%) or one-time attendance (unexplained). RESULTS We included 205,970 patients with 591,136 screenings. Rates of timely, delayed and one-time attendance were 53.0%, 35.5% and 11.5%, respectively. DR level at baseline was associated with delays (mild-, moderate-, severe NPDR and PDR) and one-time attendance (moderate-, severe NPDR and PDR) with relative risk ratios (RRR) of 1.68, 2.27, 3.14, 2.44 and 1.18, 2.07, 1.26, respectively (P < 0.05). Delays at previous screenings were associated with progression to severe NPDR or PDR (hazard ratio (HR) 2.27, 6.25 and 12.84 for 1, 2 and 3+ delays, respectively). Any given delay doubled the risk of progression (HR 2.28). CONCLUSIONS In a national cohort of 205,970 patients, almost half of the patients attended DR screening later than scheduled or dropped out after first screening episode. This was, in particular, true for patients with any levels of DR at baseline. DR progression in patients with delayed attendance, increased with the number of missed appointments.

Abstract
INTRODUCTION Exposure to perfluoroalkyl substances (PFAS) has been associated with lower bone mineral density (BMD) in animal and human studies, but prospective data from children are limited. OBJECTIVES To determine associations between prenatal and early postnatal PFAS exposure and BMD at age 7 years. METHODS In the Odense Child Cohort, Denmark, pregnant women were recruited in 2010-2012, and their children were invited for subsequent health examinations. At 12 weeks of gestation the pregnant women delivered a serum sample, and at age 18 months serum was obtained from the child to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) by LC-MS/MS. At age 7 years DXA scans were performed to measure bone mineral content (BMC) and BMD Z-score. PFAS in pregnancy (n = 924) and/or at age 18 months (n = 511) were regressed against DXA measurements, adjusted for maternal education, child height Z-score, sex (for BMC) and for postnatal exposure, additionally duration of total breastfeeding. We additionally performed structural equation models determining combined effects of pre-and postnatal PFAS exposures. RESULTS Higher prenatal and early postnatal serum concentrations of all measured PFAS were associated with lower BMC and BMD Z-scores at age 7 years, all estimates were negative although not all significant. For each doubling of prenatal or 18-month exposure to PFDA, BMD Z-scores were lowered by -0.07 (95 % CI -0.10; -0.03) and -0.14 (-0.25; -0.03), respectively after adjustment. Pre- and postnatal PFAS were correlated, but structural equation models suggested that associations with BMD were stronger for 18-month than prenatal PFAS exposure. DISCUSSION Bone density is established in childhood, and a reduction in BMD during early childhood may have long-term implication for peak bone mass and lifelong bone health. Future studies of the impact of PFAS exposure on fracture incidence will help elucidate the clinical relevance.

Abstract
OBJECTIVES Previous research has shown that patients who are older, less educated, or have lower income are less likely to lodge complaints about health care. This variation may reflect less wish to complain or inequitable access to complaint channels or remedies. We aimed to investigate associations between sociodemographic characteristics and health users' wish to complain. STUDY DESIGN This was a randomized case vignette survey among 6756 Danish men aged 45-70 years (30% response rate). METHODS Assuming they received the care in vignettes about prostate cancer (prostate-specific antigen) testing, participants rated their wish to complain on a 5-point Likert scale. Information on sociodemographic characteristics was obtained through self-reports and municipality-level information from national registries. RESULTS Lower education was associated with an increased wish to complain (mean Likert difference 0.44 [95% CI 0.36-0.51]; P < .001). The wish to complain was higher among unemployed men (difference 0.16 [95% CI 0.04-0.28]; P < .011) and those with a chronic illness (difference 0.06 [95% CI 0.02-0.10]; P < .004). Given the same healthcare scenarios, there was no difference in wish to complain among health users who were retired, living rurally, or from lower income groups. CONCLUSIONS Health users who are less educated, lower income, elderly, or from rural or minority communities appear to be as likely, or more likely, to wish to complain about health care as others. Yet, younger, well-educated, and higher income citizens are overrepresented in actual complaint statistics. The finding suggests persisting inequalities in the suitability or accessibility of complaint processes for some groups of patients.

Abstract
AIM To compare the accuracy and interobserver variation of routine computed tomography (CT) on postoperative day 6-8 to detect anastomotic leakage (AL) verified by re-operation and/or endoscopy. A secondary objective was to identify the predictive values of different CT findings as an indicator for AL. MATERIAL AND METHODS The material for this study originates from two previous prospective multicentre studies including 277 patients who were scheduled for routine abdominal CT postoperative day 6-8. Inclusion criteria for the present study were routine CT without contrast medium followed by CT with rectal contrast medium. Two independent senior radiologists blinded to the clinical outcome reviewed the CT examinations for specific findings according to a predefined scheme. RESULTS A total of 52 patients fulfilled the inclusion criteria. AL occurred in 14 patients of which nine were clinical and five subclinical. The two radiologists diagnosed AL at unenhanced CT with sensitivities of 71.4% and 50%, respectively, and of 57.1% and 35.7% with rectal contrast medium. The corresponding specificities were 55.3% and 81.6%, and 94.7% and 92.1%. Peri-anastomotic free air and contrast medium leakage had the highest odds ratios for AL. CONCLUSION The diagnostic sensitivity and specificity of routine postoperative CT to detect AL after low anterior resection for rectal cancer is low and with considerable interobserver variation.

Abstract
UNLABELLED The Charlson Comorbidity Index (CCI) may be applicable for predicting fracture risk since several diagnoses from the index are predictors of fracture. Main results were that the CCI was updated to predict risk of hip fracture with fair precision and that the index could be useful in detecting high-risk individuals. PURPOSE Several of the Charlson Comorbidity Index (CCI) diagnoses are validated predictors of fracture. The purpose of this study was to evaluate the performance of the CCI 1987 by Charlson et al. and of the CCI 2011 by Quan et al. in predicting major osteoporotic fracture (MOF) and hip fracture (HF). Furthermore, it was examined whether the index could be modified to improve fracture risk prediction. METHODS The study population included the entire Danish population aged 45 + years as per January 1, 2018. The cohort was split randomly 50/50 into a development and a validation cohort. CCI diagnoses and fracture outcomes were identified from hospital diagnoses. The weighting of diagnoses was updated in a new Charlson Fracture Index (CFI) using multivariable logistic regression. Predictive capabilities of the CCI 1987, the updated CCI 2011 and the new Charlson Fracture index were evaluated in the validation cohort by receiver operating characteristics (ROC) curves and area under the curve (AUC). RESULTS In the validation cohort, the 1987 and 2011 CCIs resulted in AUCs below or around 0.7 in prediction of MOF and HF in both sexes. The CFI resulted in AUCs < 0.7 in prediction of MOF in both sexes. In prediction of HF, the CFI resulted in AUC of 0.755 (95% CI 0.749; 0.761) in women and 0.782 (95% CI 0.772; 0.793) in men. CONCLUSION The 1987 and 2011 CCIs showed overall poor accuracy in fracture risk prediction. The CFI showed fair accuracy in prediction of HF in women and in men.

Abstract
We report on finite bias spectroscopy measurements of the two-electron spectrum in a gate defined bilayer graphene (BLG) quantum dot for varying magnetic fields. The spin and valley degree of freedom in BLG give rise to multiplets of six orbital symmetric and ten orbital antisymmetric states. We find that orbital symmetric states are lower in energy and separated by ≈ 0.4-0.8 meV from orbital antisymmetric states. The symmetric multiplet exhibits an additional energy splitting of its six states of ≈ 0.15-0.5 meV due to lattice scale interactions. The experimental observations are supported by theoretical calculations, which allow to determine that intervalley scattering and "current-current" interaction constants are of the same magnitude in BLG.

Abstract
Understanding how the electron spin is coupled to orbital degrees of freedom, such as a valley degree of freedom in solid-state systems, is central to applications in spin-based electronics and quantum computation. Recent developments in the preparation of electrostatically-confined quantum dots in gapped bilayer graphene (BLG) enable to study the low-energy single-electron spectra in BLG quantum dots, which is crucial for potential spin and spin-valley qubit operations. Here, we present the observation of the spin-valley coupling in bilayer graphene quantum dots in the single-electron regime. By making use of highly-tunable double quantum dot devices we achieve an energy resolution allowing us to resolve the lifting of the fourfold spin and valley degeneracy by a Kane-Mele type spin-orbit coupling of ≈ 60 μeV. Furthermore, we find an upper limit of a potentially disorder-induced mixing of the \documentclass[12pt]{minimal}

Abstract
Abstract
Study question
Is there an association between the hCG dose used for ovulation trigger and the endogenous progesterone production during the luteal phase?
Summary answer
Increased hCG dosing significantly increased the endogenous progesterone level during the luteal phase.
What is known already
During the luteal phase of an IVF treatment, the endogenous progesterone (P4) production is negatively impacted due to reduced circulating endogenous LH, caused by negative feed-back of elevated steroids; thus, luteal phase support (LPS) with exogenous P4 remains mandatory in IVF. Apart from inducing final oocyte maturation, the gold standard HCG trigger also functions as an early LPS, boosting P4 production by the corpora lutea (CL). P4 plays a pivotal role for embryo implantation and pregnancy, and an optimal P4 level around peri-implantation seems to be essential for the reproductive outcomes of fresh and frozen/thaw embryo transfer cycles.
Study design, size, duration
A randomized controlled 4-arm study, including a total of 127 IVF patients, enrolled from January 2015 until September 2019 at the Fertility Clinic, Odense University Hospital, Denmark.
Participants/materials, setting, methods
IVF patients with ≤ 11 follicles ≥ 12 mm were randomized to four groups. Groups 1-3 were triggered with: 5.000 IU, 6.500 IU or 10.000 IU, hCG, respectively, receiving a LPS consisting of 17-α-hydroxy-progesterone (17α OH P4) to distinguish the endogenous P4 from the exogenous supplementation. Group 4 (control) was randomized to a 6.500 IU hCG trigger and standard LPS. A total of eight blood samples were drawn during the early luteal phase.
Main results and the role of chance
A total of 94 patients completed the study: 21, 22, 25 and 26 patients in each group, respectively. Baseline characteristics were similar, except for the endogenous LH level and cycle lengths. There were no significant differences between groups regarding ovarian stimulation, number of oocytes and embryos. The median number of follicles ≥ 12mm on the day of trigger was 8.5, resulting in 6.6 oocytes being retrieved. Significant differences in P4 levels were seen at OPU+8 (p < 0.001), OPU+10 (p < 0.001) and OPU+14 (p < 0.001), with positive correlations between P4 level and hCG dose. Groups compared individually showed significant difference in P4 between low and high trigger dose at OPU+4 group 1 and 3 (p = 0.037) and OPU+8 group 1 and 3 (p = 0.007) and between all the three groups around implantation at OPU+6 group 1 and 2 (p = 0.011), group 2 and 3 (p = 0.042) and group 1 and 3 (p < 0.001). Higher P4 levels around implantation were related to follicle count and to pregnancy. After logistic regression analyses there were still significant individual differences between the groups.
Limitations, reasons for caution
Although patients were randomized and strict inclusion and exclusion criteria were used, the RCT was un-blinded, including a relatively small number of patients. Moreover, for dosing purposes urinary hCG as well as recombinant hCG was used and pharmacokinetics differ. Finally, the P4 level could be influenced by circadian fluctuations.
Wider implications of the findings
This is the first study to explore dose-responses in circulating P4 after hCG trigger in IVF patients. Increasing the hCG trigger dose increased the endogenous P4 around peri-implantation. Personalizing the hCG trigger dose could be a key point to secure the most optimal P4 mid-luteal phase P4 level.

Abstract
STUDY QUESTION Is fecundity, measured as self-reported time to first pregnancy (TTP), a marker for subsequent health and survival? SUMMARY ANSWER Long TTP was a marker for increased mortality among women and higher hospitalization rates for both women and men. WHAT IS KNOWN ALREADY Poor semen quality has been linked to increased mortality and morbidity from a wide range of diseases. Associations among fecundity, health and survival among women are still uncertain and studies on actual measures of fecundity and health outcomes are rare. STUDY DESIGN, SIZE, DURATION We performed a prospective cohort study of 7825 women and 6279 men, aged 18 and above with measures on first TTP, who participated in one of the Danish nation-wide twin surveys in 1994 (twins born 1953-1976) and 1998 (twins born 1931-1952). They were followed-up for mortality and hospital admissions from the interview until 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Twins were identified in the Danish Twin Registry and linked to Danish registers. TTP was restricted to the first pregnancy as a categorical outcome with cut-off points at 2, 10 and 18 months. We analysed the association between TTP and survival using a Cox proportional hazards model estimating hazards ratios (HRs) with 95% confidence intervals (CIs). Fine-Gray survival models were used to estimate sub-hazard ratios for specific causes of death allowing for competing risks. Using negative binomial regression, we estimated incidence rate ratios (IRRs) with 95% CIs for all-cause and cause-specific hospitalizations. All analyses were stratified by sex and adjusted for age at interview, birth cohorts, age at first attempt to become pregnant, smoking, years in school and BMI. MAIN RESULTS AND THE ROLE OF CHANCE In the total study population, 49.9% of women and 52.7% of men reported a TTP of less than 2 months, 30.8% of women and 29.6% of men reported a TTP of 2-9 months, 6.6% of women and 5.7% of men reported a TTP of 10-17 months, and 13.3% of women and 12.0% of men reported a TTP of 18 months or more. Among 1305 deaths, we found a higher mortality for women (HR = 1.46; 95% CI 1.15, 1.87) with a TTP of ≥18 months relative to those with a TTP of <2 months, while the highest mortality was indicated for men with a TTP of 10-17 months (HR = 1.31; 95% CI 0.98, 1.74). Among 53 799 hospitalizations, we found an increased hospitalization rate among women (HR = 1.21; 95% CI 1.0-1.41) and men (HR = 1.16; 95% CI 1.00-1.35) with a TTP of ≥18 months, and for men with a TTP of 2-9 months (HR = 1.14; 95% CI 1.01-1.30). A dose-response relationship was found for women regarding both mortality (P = 0.022) and hospitalizations (P = 0.018). Impaired fecundity was associated with a wide range of diseases and some causes of death, indicating a multi-factorial causal influence on fecundity, especially among women. LIMITATIONS, REASONS FOR CAUTION A major limitation was that fecundity depends on both partners, which was not considered in this study. Moreover, we could not obtain information on a number of potential confounders. WIDER IMPLICATIONS OF THE FINDINGS Fecundity seems positively correlated with overall health and may be a universal marker of future health and survival. These results add knowledge to the limited findings showing that reduced fecundity in women and poor semen quality in men may reflect worse health and a shorter life, particularly among women. STUDY FUNDING/COMPETING INTEREST(S) This study was funded by NIH grant HD096468 (M.L.E., T.K.J. and R.L.J.). The authors declare that they have no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
Background:Although causality remains to be established, targeting dysbiosis of the intestinal microbiota by faecal microbiota transplantation (FMT) has been proposed as a novel therapeutic option for treatment of extra-intestinal inflammatory diseases.1Objectives:In this proof-of-concept study, we evaluated efficacy and safety of FMT in psoriatic arthritis (PsA).2Methods:In this double-blind, parallel-group, sham-controlled, superiority trial, we randomly allocated (1:1) adults with active peripheral PsA (≥3 swollen joints) despite ongoing treatment with methotrexate to one gastroscopic-guided FMT or sham transplantation into the duodenum. The transplants (50 g faeces) came from one of four healthy, thoroughly screened, anonymous stool donors.3 The primary efficacy endpoint was the proportion of participants experiencing treatment failure (i.e., needing treatment intensification) through 26 weeks. The first key secondary endpoint was change in Health Assessment Questionnaire Disability Index (HAQ-DI) score from baseline to week 26. Safety was monitored throughout the trial. Trial registration number: NCT03058900, ClinicalTrials.gov.Results:Of 97 screened, 31 (32%) underwent randomisation (15 allocated to FMT), all received the assigned intervention, and 30 (97%) completed the 26-week clinical evaluation (Table 1). Treatment failure occurred more frequently in the FMT group than in the sham group (9 [60%] vs 3 [19%]; risk ratio, 3.20; 95% CI, 1.06 to 9.62; P=0.018). During the entire 26 weeks of observation, the rate of the treatment failures was significantly higher in the FMT than in the sham group, see figure 1. Improvement in HAQ-DI score differed between groups (0.07 vs 0.30) by 0.23 points (95% CI, 0.02 to 0.44; P=0.031) in favour of sham. No serious adverse events were observed.Conclusion:In this first interventional randomised controlled trial of FMT in immune-mediated arthritis, FMT was inferior to sham in treating active peripheral PsA. FMT did not appear to result in serious adverse events.Figure 1.Time-to-event curves by intervention group from baseline to week 26.

Abstract
Background:We lack knowledge of how gender, disease characterization, and measures of various Patient Reported Outcome Measures (PROMS) relate to Methotrexate (MTX) usage in patients with rheumatoid arthritis.Objectives:To investigate the impact of gender on physical function, fatigue, depression, loneliness, and sexual functioning with a special focus on MTX usage.Methods:A cross-sectional study design was used to collect data in a rheumatologic outpatient clinic. The following PROMs were applied: Changes in Sexual Functioning Questionnaire, UCLA Loneliness Scale, Beck´s Depression Inventory, Bristol Rheumatoid Arthritis Fatigue-Numeric Rating Scale, and the Health Assessment Questionnaire.Results:Among 286 patients diagnosed with rheumatoid arthritis (69 men and 217 women), 67.8 % were defined as MTX-users one year after diagnosis.Comparing women and men we found differences in PROMS, with significantly worse outcomes for women than men in physical functioning at diagnosis and in sexual functioning, depression, fatigue, physical functioning, and patient evaluation of disease burden at enrolment in the study.There were only significant differences in the HAQ and loneliness score when comparing MTX-users with MTX-non-users in general (Table 1).Conclusion:The results of this study show that women have more negative outcomes on the selected PROMs compared to men with RA. This difference between genders was also evident when comparing MTX-users with non-MTX-users, again with a poorer outcome on PROMs for women compared to men. This calls for attention in the clinical setting and further research in the used instruments and the importance of gender in the care and treatment of patients with RA.Table 1.Second column is adjusted for gender, patient age, years of education, and living alone, all other columns are not adjusted for gender.

Abstract
OBJECTIVE Primarily to understand whether clinically relevant factors affect the International Outcome Inventory (IOI-HA) scores and to examine if IOI-HA scores improve when renewing the hearing aids (HA) for experienced users. Secondly, to estimate the overall HA effectiveness using the IOI-HA. DESIGN A prospective observational study. STUDY SAMPLE In total, 1961 patients with hearing loss were included. All patients underwent a hearing examination, were fitted with HAs, and answered the IOI-HA. Factor analysis of IOI-HA separated the items into a Factor 1 (use of HA, perceived benefits, satisfaction, and quality of life) and Factor 2 (residual activity limitation, residual participation restriction and impact on others) score. RESULTS Degree of hearing loss, word recognition score, motivation, HA usage time, tinnitus, asymmetry, and sex were significantly associated with total IOI-HA, Factor 1, or Factor 2 scores. The seven IOI-HA items increased on average by 0.4 (p < 0.001) when renewing HAs. The total median IOI-HA score at follow-up was 29 (7) for experienced (n = 460) and first-time users (n = 1189), respectively. CONCLUSIONS Degree of hearing loss, word recognition score, motivation, tinnitus, asymmetry, and sex may be used to identify patients who require special attention to become successful HA users.

Abstract
The Toroidal Magnetized System device has been significantly upgraded to enable development of various wall conditioning techniques, including methods based on ion and electron cyclotron (IC/EC) range of frequency plasmas, and to complement plasma-wall interaction research in tokamaks and stellarators. The toroidal magnetic field generated by 16 coils can reach its maximum of 125 mT on the toroidal axis. The EC system is operated at 2.45 GHz with up to 6 kW forward power. The IC system can couple up to 6 kW in the frequency range of 10 MHz-50 MHz. The direct current glow discharge system is based on a graphite anode with a maximum voltage of 1.5 kV and a current of 6 A. A load-lock system with a vertical manipulator allows exposure of material samples. A number of diagnostics have been installed: single- and triple-pin Langmuir probes for radial plasma profiles, a time-of-flight neutral particle analyzer capable of detecting neutrals in the energy range of 10 eV-1000 eV, and a quadrupole mass spectrometer and video systems for plasma imaging. The majority of systems and diagnostics are controlled by the Siemens SIMATIC S7 system, which also provides safety interlocks.

Abstract
AIM The aim was to investigate the overall postoperative complication rate within 90 days following ileal pouch-anal anastomosis (IPAA), with or without a diverting stoma, together with complications 30 days after stoma closure and overall pouch failure rate. METHOD This was a retrospective chart review including IPAA patients with or without a diverting loop-ileostomy for ulcerative colitis (1 January 1983 to 31 December 2015). Demographic data and postoperative complications were retrieved and recorded. RESULTS A total of 434 patients were included. A diverting loop-ileostomy was performed in 348 patients (80%). Baseline data were similar in the two groups except for body mass index (BMI) and the ratio of women, which were significantly higher in the group without a protective ileostomy. Overall 90-day complication rate after IPAA [Clavien-Dindo (CD) > 2] was similar in the two groups. Clinical anastomotic leaks (CD > 2) were higher in patients without a diverting stoma (9.3% vs 1.7%) (P = 0.002). The odds ratio for leakage after adjustments (age, gender, immune-modulating medicine and BMI) was 5.0 for omitting a diverting stoma (P = 0.004). Complications (CD > 2) after loop-ileostomy closure were seen in 61 cases (14.1%). Omitting a diverting stoma at IPAA demonstrated a non-significant odds ratio of 1.04 (0.46, 2.38) (P = 0.924) for pouch failure after adjustments (age, gender, immune-modulating medicine, BMI, time from pouch formation and clinical leakage). CONCLUSION The overall postoperative surgical and medical complication rate within 90 days after IPAA was similar in the group with and without diverting stoma. Postoperative complication rate after reversal was 14%. Omitting a diverting stoma at IPAA demonstrated an increased risk of leaks but no significant risk of long-term pouch failure.

Abstract
Introduction Walking with a prosthesis while performing secondary tasks increases demand on cognitive resources, compromising balance and gait. This study investigated effects of a secondary task on patterns of brain activity and temporospatial gait parameters in individuals using a prosthesis with or without a microprocessor-controlled prosthetic knee(MPK) and controls. Methods A cross-sectional study with repeated measures was performed. Twenty-nine individuals with amputations and 16 controls were recruited. Functional near-infrared spectroscopy was used to evaluate changes in oxygenated and de-oxygenated haemoglobin in the prefrontal cortex and temporospatial variables during single-and dual-task walking. Results Differences in brain activity were observed within the MPK-group and controls without changes in temporospatial parameters. The Trail-Walking test was associated with highest levels of brain activity in both groups. No differences were observed between single- and dual-task walking in the non-MPK-group (p > 0.05). The Non-MPK and the MPK-group recorded higher levels of brain activity than controls during single-task walking and poorer results on temporospatial variables compared to controls. Conclusions For the MPK-group and controls, introduction of a secondary task led to an increase in brain activity. This was not seen in the Non-MPK-group. Significant differences in brain activity were observed in the absence of changes in temporospatial parameters.

Abstract
Electron and hole Bloch states in bilayer graphene exhibit topological orbital magnetic moments with opposite signs, which allows for tunable valley-polarization in an out-of-plane magnetic field. This property makes electron and hole quantum dots (QDs) in bilayer graphene interesting for valley and spin-valley qubits. Here, we show measurements of the electron-hole crossover in a bilayer graphene QD, demonstrating opposite signs of the magnetic moments associated with the Berry curvature. Using three layers of top gates, we independently control the tunneling barriers while tuning the occupation from the few-hole regime to the few-electron regime, crossing the displacement-field-controlled band gap. The band gap is around 25 meV, while the charging energies of the electron and hole dots are between 3 and 5 meV. The extracted valley g-factor is around 17 and leads to opposite valley polarization for electrons and holes at moderate B-fields. Our measurements agree well with tight-binding calculations for our device.

Abstract
Dickkopf-1 (DKK1), a Wnt inhibitor secreted by bone marrow stromal cells (MSC), is known to play an important role in long-term non-union bone fracture defects and glucocorticoid induced osteoporosis. Mitigating its effects in early bone defects could improve osteogenesis and bone defect healing. Here, we applied a biomaterial strategy to deplete a defect environment from DKK1 by scavenging the protein via a macromer-based biomaterial covalently decorated with sulfated hyaluronan (sHA3). The material consisted of cross-copolymerized three-armed macromers with a small anchor molecule. Using the glycidyl anchor, polyetheramine (ED900) could be grafted to the material to which sHA3 was efficiently coupled in a separate step. For thorough investigation of material modification, flat material surfaces were generated by fabricating them on glass discs. The binding capability of sHA3 for DKK1 was demonstrated in this study by surface plasmon resonance measurements. Furthermore, the surfaces demonstrated the ability to scavenge and inactivate pathologic amounts of DKK1 from complex media. In a combinatory approach with Wnt3a, we were able to demonstrate that DKK1 is the preferred binding partner of our sHA3-functionalized surfaces. We validated our findings in a complex in vitro setting of differentiating SaOS-2 cells and primary hMSC. Here, endogenous DKK-1 was scavenged resulting in increased osteogenic differentiation indicating that this is a consistent biological effect irrespective of the model system used. Our study provides insights in the mechanisms and efficiency of sHA3 surface functionalization for DKK1 scavenging, which may be used in a clinical context in the future.

Abstract
Background:Low vitamin D levels are common in Rheumatoid Arthritis (RA)1, and possibly associated with disease course,2but data on vitamin D levels during long-term disease course has not been reported previously.Objectives:To describe vitamin D trajectories from time of diagnosis through 10 years follow-up in early diagnosed RA patients.Methods:The CIMESTRA trial included 160 newly diagnosed RA-patients, treated aiming at remission with methotrexate and intraarticular steroid, further randomized to ciclosporine or placebo. Vitamin D supplementation was recommended according to national guidelines. Vitamin Dtotalwas measured at diagnosis, and year 1, 5 and 10 using LC-MS/MS. 1,25(OH)2D was measured at diagnosis and year 1 using RIA. Linear mixed effects models were used to study vitamin D levels serially. We had fixed effects for time, and patients modelled as a random effect. We tested the hypothesis that percentage of patients achieving Dtotal≥ 50 nmol/l during follow-up was 90%. Analyses of associations between Dtotaland DAS28-CRP during the disease-course were adjusted for age, sex, symptom-duration prior to diagnosis and season of diagnosis.Results:Median Dtotalat baseline was 53 nmol/l (IQR 36-567.8). Dtotalincreased significantly during follow-up, independently of level at diagnosis (p<0.001). Individuals achieving Dtotal≥50nmol/l during follow-up was 80-87%, but not as high as 90% at year 1 and 5, p<0.002. DAS28-CRP during disease-course was inversely associated with Dtotaltrajectories only in crude (β-coefficient (β) -0.0034, 95%CI (-0.007; -0.0002) p=0.039) and partially adjusted analyses (β -0.003, 95%CI (-0.007; -0.002) p=0.04). Estimate was left insignificant in fully adjusted analyses (β -0.003, 95%CI (-0.0006; 0.0001) p=0.06). 1,25(OH)2D levels did not change significantly during follow-up (p=1.00).Conclusion:Dtotalincreased significantly during follow-up, but fewer than 90% achieved the recommended 50 nmol/l at year 1 and 5. Disease activity during follow-up was associated with Dtotaltrajectories only in partially adjusted analyses, while adjustment for possible confounders left estimates insignificant. Results suggest vitamin D supplementation to be recommended in all RA patients.References:Reference List[1]Herly M, Stengaard-Pedersen K, Vestergaard P, et al.

Abstract
Background:Systemic inflammation in rheumatoid arthritis (RA) is associated with reduced serum lipid levels (LL) and treatment with disease modifying antirheumatic drugs has been associated with increased serum LL [1]. It is unclear whether the changes in serum LL reported in association with adalimumab (ADA) treatment are due to suppressed inflammation or the ADA treatmentper se.Objectives:The primary objective was to compare the effect of ADA + methotrexate (MTX) to placebo (PBO) + MTX on changes in low density lipoprotein cholesterol (LDL-C) from baseline to month 12 in patients with early- and treatment naïve RA. Secondary objectives were to compare the treatment groups on changes in total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides, very low density lipoprotein cholesterol (VLDL-C) and non-HDL-C (=TC – HDL-C).Methods:We present secondary analyses from the OPERA trial, which was an investigator-initiated, multicenter double-blind, placebo-controlled, treat-to-target trial of 180 early and treatment naïve RA patients, who were randomized (1:1) to oral MTX 20 mg once a week in combination with either PBO or ADA 40 mg SC EOW [2]. Any swollen joint was injected with triamcinolone hexacetonide. Lipid profiles of each patient were assessed at baseline and 12 months. All randomized patients with available LDL-C at baseline were included in Intention To Treat (ITT) analysis. Sensitivity analyses were performed on the Per Protocol (PP) and the ITT population with baseline observations carried forward (BOCF). All analyses were based on repeated measurements using mixed linear models.Results:In total, 174 patients (97% of the original OPERA trial population) were included in ITT analysis (ADA n=86; PBO n=88) and 156 patients (ADA n=78; PBO n=78) completed the study with LDL-C measurements at both baseline and 12 months (PP). At baseline mean LDL-C was 2.9 mmol/L (SD 0.9) with 63 (36.2%) patients having an LDL-C above 3.0 mmol/L. There was no significant difference in LDL-C change between ADA+MTX and PBO+MTX groups after 12 months. A nearly statistically significant between-group difference in TC change was found. Other changes in LL were comparable across the two groups. Results in ITT, PP and ITT with BOCF populations were similar.Conclusion:In early RA patients treated to target with methotrexate and intra-articular triamcinolone, 12 months with the addition of adalimumab did not affect lipid levels.References:[1]England BRet al., Bmj2018;361:k1036[2]Hørslev-Petersen Ket al.,Ann Rheum Dis2014;73:654–61Disclosure of Interests:Dzenan Masic: None declared, Kristian Stengaard-Pedersen: None declared, Brian Bridal Løgstrup: None declared, Kim Hørslev-Petersen Grant/research support from: Pfizer (Travel expences), Merete L.

Abstract
Background:Physical activity is important for enhancing health and the World Health Organization (WHO) recommends that adults aged 18-64 engage in at least 150 minutes of moderate-intensity physical activity throughout the week, or 75 minutes of vigorous-intensity physical activity (1). Swedish patients with SLE reported a lower frequency and capacity of exercise than a control group, and in an Italian study, 60% of the SLE patients did not meet WHO’s recommendations for physical activity.Mental health is important for the individual’s level of physical activity, and symptoms of depression have been associated with a lower level of physical activity in SLE patients (2).Objectives:The aim of this study is to describe the pattern of physical activity in a population of Danish SLE patients, and to investigate the association to depression.Methods:The study was conducted at the Department of Rheumatology at Odense University Hospital, Denmark, in 2018 and 2019. Two questionnaires were handed out before routine outpatient consultation: self-reported physical activity was evaluated using the International Physical Activity Questionnaire (IPAQ), and a continuous variable on energy requirement in the form of the metabolic equivalent (MET) was calculated, and the Major Depression Inventory (MDI) questionnaire was used to screen for depression. Medicine intake was registered, and disease activity and damage were scored using SLEDAI-2K and SLICC/ACR DI.Results:Two hundred and fifteen patients completed the IPAQ and MDI, 5 were excluded. The population consist of 89.5% women and the mean age was 51.7 ± 15.2 years. The mean disease duration was 16.1 ± 10.1 years.The SLE patients reported a mean total MET-score of 5319.9 ± 3650 MET-min/week. If divided into categories, 7.6% reported low level, 21.9% moderate and 70.5% of the patients reported a high level of physical activity and 89.5% fulfilled WHO recommendations. The participants reported 363.7 ± 201 minutes per day in sitting time.Mean MDI score was 12.7 ± 10.1, and if divided into groups, 89.5% were not depressed, 1.9% had a mild depression, 5.3% had a moderate depression and 2.9% had a severe depression. Significantly lower mean MET-scores were observed for the severely depressed patients.An inverse association was found in the univariate analysis, indication that increasing disease duration and SLICC/ACR DI scores were significantly associated with decreasing total MET-scores. In the multivariate analysis time spent sitting was inversely associated with MET-score.Our results were similar to a Brazilian study, where 68% of the patients reported, that they were “physical active” according to IPAQ. In contrast, only 22% of the patients in an Italian study reported high level physical activity. Our proportion of active patients were high when comparing with studies on patients with rheumatoid arthritis and spondylarthritis, where only 25-50% fulfilled the WHO recommendations compared to our 89.5%.A Danish study on registered ICD diagnoses found a prevalence of depression in SLE patients to be 4.3%, which was lower than our prevalence. Foreign studies reported very diverse prevalences of depression, e.g. 16.6% in the Netherlands and 51% in Sweden.Conclusion:A high portion of the SLE patients reported a high level of physical activity and 89.5% fulfilled the WHO recommendations. Significant predictors for a lower level of physical activity were increasing disease duration, higher SLICC/ACR DI score and longer time spent sitting.

Abstract
The study evaluates associations between serum vitamin D metabolites at diagnosis and one-year remission, in early diagnosed rheumatoid arthritis(RA). The CIMESTRA-cohort comprised 160 newly diagnosed RA patients, treated aiming at remission. Vitamin D supplementation was recommended according to national guidelines. Dtotal(25OHD2 + 25OHD3) was dichotomized at 50 nmol/L, 1,25(OH)2D was categorized in tertiles. Primary outcome was remission(DAS28-CRP ≤ 2.6) after one year. Associations were evaluated using logistic regression, further adjusted for pre-specified potential confounders: Age, sex, symptom-duration before diagnosis, DAS28-CRP and season of diagnosis. Results are presented as Odds Ratios(OR) with 95% Confidence Intervals(95%CIs). In univariate analyses, neither Dtotal nor 1,25(OH)2D were associated with remission. In adjusted analyses, low Dtotal was associated with higher odds for remission; OR 2.6, 95%CI (1.1; 5.9) p = 0.03, with season impacting results the most. One-year remission was lower in patients with diagnosis established at winter. In conclusion, low Dtotal at diagnosis was associated with increased probability of achieving one-year remission in early RA when adjusting for covariates. Diagnosis in winter was associated with lower odds for one-year remission. Results suggest that season act as a contextual factor potentially confounding associations between vitamin D and RA disease-course. The finding of low Dtotal being associated with higher one-year remission remains speculative.

Abstract
Lithium diffusion in LiMn2O4 pellets is studied by means of isotope exchange and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). A 6Li-enriched film deposited by Pulsed Laser Deposition (PLD) on a dense LiMn2O4 pellet with natural abundance of lithium isotopes is used to study the tracer diffusion of lithium. The measured profiles are analyzed by numerical models describing the 6Li tracer diffusion from the film into the pellet. Experiments in the Harrison type B regime of diffusion kinetics allow for the distinction and simultaneous determination of bulk and grain boundary diffusion coefficients. Changing the experimental conditions to reach Harrison type A behavior yields effective diffusion coefficients for lithium tracer diffusion in LiMn2O4. Activation energies for bulk and grain boundary diffusion were obtained from experiments at different temperatures. Our values are critically compared to previous studies.

Abstract
Recent research in religiousness and health suggests that epidemiological forces can have opposed effects. Here we examine two forms of religiousness and their association with disease. We performed a cross-sectional study of 23,864 people aged 50+ included in wave 1 (2004-2005) of the Survey of Health, Ageing and Retirement in Europe and a longitudinal study including people from wave 1, who were followed up during 11 years. Results suggested that taking part in a religious organization was associated with lower odds of heart attack (OR 0.74, 95% CI 0.60, 0.90), stroke (OR 0.68, 95% CI 0.50, 0.95), and diabetes (OR 0.72, 95% CI 0.58, 0.90) and longitudinally associated with lower odds of cancer (OR 0.78, 95% CI 0.60, 1.00). Conversely, praying was longitudinally associated with higher odds of heart attack (OR 1.27, 95% CI 1.10, 1.48) and high cholesterol (OR 1.12, 95% CI 1.00, 1.26). The most religious people had lower odds of stroke, diabetes, and cancer than other respondents, and in the longitudinal model, people who only prayed had higher odds of heart attack than non-religious people. Our findings lend support to the hypothesis that restful religiousness (praying, taking part in a religious organization, and being religiously educated) was associated with lower odds of some diseases, whereas little evidence was present that crisis religiousness (praying only) was associated with higher odds of disease.

Abstract
UNLABELLED Use of antiosteoporotic medication in the population-based, risk-stratified osteoporosis strategy evaluation (ROSE) screening study, comparing the use of FRAX followed by DXA with usual care, was examined. Screening increased the overall use of medication. Being recommended treatment by the hospital and higher age increased the likelihood of starting medication, but, nevertheless, a large percentage opted not to start treatment. INTRODUCTION The aim of the study was to examine the impact on medication prescription, adherence, and persistence of osteoporotic medicine in the randomized population-based ROSE screening study for osteoporosis. METHODS The Danish ROSE study included a population-based random sample of women aged 65-81 years randomized to either a two-step screening program consisting of FRAX followed by DXA for high-risk participants or opportunistic screening for osteoporosis (usual care). This sub-study on the intention-to-treat population examined the impact of the screening program on antiosteoporotic medication redemption rates, adherence, and persistence using Danish registers. RESULTS A total of 30,719 of 34,229 women were treatment-naïve. Significantly more participants in the screening group started on antiosteoporotic medication, but no differences in adherence and persistence rates were found. Higher age was associated with a higher likelihood of starting medication. A low Charlson comorbidity score (= 1) was associated with higher treatment initiation but lower adherence and persistence of antiosteoporotic treatment. A total of 31.7% of participants advised to initiate treatment did not follow the advice. CONCLUSIONS Screening for osteoporosis using FRAX followed by DXA increased the overall use of antiosteoporotic medication in the screening group without differences in adherence and persistence rates. A large percentage of participants advised to initiate treatment did nevertheless fail to do so.

Abstract
BACKGROUND Individuals using a lower-limb prosthesis indicate that they need to concentrate on every step they take. Despite self-reports of increased cognitive demand, there is limited understanding of the link between cognitive processes and walking when using a lower-limb prosthesis. OBJECTIVE The objective was to assess cortical brain activity during level walking in individuals using different prosthetic knee components and compare them to healthy controls. It was hypothesized that the least activity would be observed in the healthy control group, followed by individuals using a microprocessor-controlled prosthetic knee and finally individuals using a non-microprocessor-controlled prosthetic knee. STUDY DESIGN Cross-sectional study. METHODS An optical brain imaging system was used to measure relative changes in concentration of oxygenated and de-oxygenated haemoglobin in the frontal and motor cortices during level walking. The number of steps and time to walk 10 m was also recorded. The 6-min walk test was assessed as a measure of functional capacity. RESULTS Individuals with a transfemoral or knee-disarticulation amputation, using non-microprocessor-controlled prosthetic knee ( n = 14) or microprocessor-controlled prosthetic knee ( n = 15) joints and healthy controls ( n = 16) participated in the study. A significant increase was observed in cortical brain activity of individuals walking with a non-microprocessor-controlled prosthetic knee when compared to healthy controls ( p < 0.05) and individuals walking with an microprocessor-controlled prosthetic knee joint ( p < 0.05). CONCLUSION Individuals walking with a non-microprocessor-controlled prosthetic knee demonstrated an increase in cortical brain activity compared to healthy individuals. Use of a microprocessor-controlled prosthetic knee was associated with less cortical brain activity than use of a non-microprocessor-controlled prosthetic knee. CLINICAL RELEVANCE Increased understanding of cognitive processes underlying walking when using different types of prosthetic knees can help to optimize selection of prosthetic components and provide an opportunity to enhance functioning with a prosthesis.

Abstract
UNLABELLED There is a need of studies exploring the link between socioeconomic status and DXA scans and osteoporotic fracture, which was the aim of the present study. No differences in socioeconomic status and risk of osteoporotic fractures were found. However, women with further/higher education and higher income are more often DXA-scanned. INTRODUCTION Lower socioeconomic status is known to be associated with a range of chronic conditions and with access to health care services. The link between socioeconomic status and the use of DXA scans and osteoporotic fracture, however, needs to be explored more closely. Therefore, the aim of this study was to examine the relationship between socioeconomic status and both DXA scan utilization and major osteoporotic fractures (MOF) using a population-based cohort of Danish women and national registers. METHODS The study included 17,155 women (65-81 years) sampled from the Risk-stratified Osteoporosis Strategy Evaluation study (ROSE). Information on socioeconomic background, DXA scans, and MOFs was retrieved from national registers. Competing-risk regression analyses were performed. Mean follow-up was 4.8 years. RESULTS A total of 4245 women had a DXA scan (24.7%) and 1719 (10.0%) had an incident MOF during follow-up. Analyses showed that women with basic education had a lower probability of undergoing DXA scans than women with further or higher education (greater than upper secondary education and vocational training education) (subhazard ratio (SHR) = 0.82; 95% CI 0.75-0.89, adjusted for age and comorbidity). Moreover, women with disposable income in the low and medium tertiles had a lower probability of undergoing DXA scans than women in the high-income tertile (SHR = 0.90; 95% CI 0.84-0.97 and SHR = 0.88, 95% CI 0.82-0.95, respectively, adjusted for age and comorbidity). No association between socioeconomic background and probability of DXA was found in adjusted analyses. CONCLUSION The study found no differences in risk of osteoporotic fractures depending on socioeconomic status. However, women with further or higher education as well as higher income are more often DXA-scanned.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of incisional negative pressure wound therapy (iNPWT) in preventing surgical site infection in obese women after caesarean section. DESIGN A cost-effectiveness analysis conducted alongside a clinical trial. SETTING Five obstetric departments in Denmark. POPULATION Women with a pregestational body mass index (BMI) ≥30 kg/m2 . METHOD We used data from a randomised controlled trial of 876 obese women who underwent elective or emergency caesarean section and were subsequently treated with iNPWT (n = 432) or a standard dressing (n = 444). Costs were estimated using data from four Danish National Databases and analysed from a healthcare perspective with a time horizon of 3 months after birth. MAIN OUTCOME MEASURES Cost-effectiveness based on incremental cost per surgical site infection avoided and per quality-adjusted life-year (QALY) gained. RESULTS The total healthcare costs per woman were €5793.60 for iNPWT and €5840.89 for standard dressings. Incisional NPWT was the dominant strategy because it was both less expensive and more effective; however, no statistically significant difference was found for costs or QALYs. At a willingness-to-pay threshold of €30,000, the probability of the intervention being cost-effective was 92.8%. A subgroup analysis stratifying by BMI shows that the cost saving of the intervention was mainly driven by the benefit to women with a pre-pregnancy BMI ≥35 kg/m2 . CONCLUSION Incisional NPWT appears to be cost saving compared with standard dressings but this finding is not statistically significant. The cost savings were primarily found in women with a pre-pregnancy BMI ≥35 kg/m2 . TWEETABLE ABSTRACT Prophylactic incisional NPWT reduces the risk of SSI after caesarean section and is probably dominant compared with standard dressings #healtheconomics.
