Abstract
BACKGROUND While left bundle branch block (LBBB) is a well-known risk feature in patients with acute myocardial infarction and a rapid invasive management is recommended, data supporting this strategy for patients with right bundle branch block (RBBB) is less robust. METHODS In total, 2,139 patients with suspected ST-elevation myocardial infarction (STEMI) were triaged to acute coronary angiography based on a prehospital 12-lead ECG. Sensitivity and specificity for STEMI-ECG-criteria were compared in RBBB and non-BBB patients. Adjusted hazard ratios for 1-year overall mortality were computed. RESULTS STEMI was adjudicated in 1,832/2,139 (85.6%) of all patients and in 102/117 (87.2%) of RBBB patients. ST-segment deviation followed typical ST-T patterns in most RBBB patients. Out of 17 RBBB patients without significant ST-changes STEMI was adjudicated in 14 (82%). Diagnostic accuracy of STEMI-criteria was comparable in RBBB and non-RBBB patients for inferior (sensitivity: 51.1% vs 59.1%, p=0.14; specificity: 66.7% vs 52.1%, p=0.33) and anterior STEMI (sensitivity: 35.2% vs 36.6%, p=0.80; specificity: 58.3% vs 49.5%, p=0.55). Diagnostic performance was lower for lateral STEMI in RBBB patients (sensitivity: 14.8% vs 4.4%, p=0.001; specificity: 75.0% vs 98.4%, p<0.001). Patients with RBBB had higher 1-year mortality compared to non-BBB patients (hazard ratio 2.3% (95% CI 1.25-4.21). CONCLUSION ECG-criteria used for detection of STEMI showed comparable diagnostic accuracy in RBBB and non-BBB patients. However, STEMI was frequently present in RBBB patients not fulfilling diagnostic ECG-criteria. RBBB-patients showed poorer outcome after 1 year. Consequently, the presence of RBBB in suspected STEMI cases signifies a high-risk feature, aligning with established guidelines.

Abstract
BACKGROUND Nonsuicidal self-injury (NSSI) is highly prevalent in adolescents. In survey and interview studies assessing NSSI, methods of assessment have been shown to influence prevalence estimates. However, knowledge of which groups of adolescents that are identified with different measurement methods is lacking, and the characteristics of identified groups are yet to be investigated. Further, only a handful of studies have been carried out using exploratory methods to identify subgroups among adolescents with NSSI. METHODS The performance of two prevalence measures (single-item vs. behavioral checklist) in the same cross-sectional community sample (n = 266, age M = 14.21, 58.3% female) of adolescents was compared regarding prevalence estimates and also characterization of the identified groups with lifetime NSSI prevalence. A cluster analysis was carried out in the same sample. Identified clusters were compared to the two groups defined using the prevalence measures. RESULTS A total of 118 (44.4%) participants acknowledged having engaged in NSSI at least once. Of these, a group of 55 (20.7%) adolescents confirmed NSSI on a single item and 63 (23.7%) adolescents confirmed NSSI only on a behavioral checklist, while denying NSSI on the single item. Groups differed significantly, with the single-item group being more severely affected and having higher mean scores on difficulties in emotion regulation, self-criticism, number of methods, higher frequency of NSSI, higher rates of suicidal ideation and suicidal behavior and lower mean score on health-related quality of life. All cases with higher severity were not identified by the single-item question. Cluster analysis identified three clusters, two of which fit well with the groups identified by single-item and behavioral checklist measures. CONCLUSIONS When investigating NSSI prevalence in adolescents, findings are influenced by the researchers' choice of measures. The present study provides some directions toward what kind of influence to expect given the type of measure used, both with regards to the size of the identified group and its composition. Implications for future research as well as clinical and preventive work are discussed.

Abstract
BACKGROUND Nonsuicidal self-injury (NSSI) is associated with stigma, and negative attitudes among healthcare professionals toward NSSI have been reported. A person-centered approach that focuses on how individuals with lived experience of NSSI perceive the treatment and care they receive is invaluable in reducing barriers to help-seeking and improving treatment and mental healthcare services. The aim of the current qualitative study was to explore the perceptions of young adults when they look back upon their experiences of psychiatric treatment for NSSI during adolescence. METHODS Twenty-six individuals with lived experience of NSSI who were in contact with child and adolescent psychiatry during adolescence were interviewed. The interviews were analyzed using thematic analysis. RESULTS Three main themes were developed: Changed perceptions in retrospect, The importance of a collaborative conceptualization and Lasting impression of the relationship. Participants' perception of themselves as well as the treatment changed over time. The importance of a joint understanding of NSSI and an agreed-upon treatment focus was emphasized. The relationship to the mental health professionals, and experiences of how NSSI was communicated, were salient several years later. CONCLUSIONS Healthcare professionals need to communicate about NSSI in a respectful manner and include the perspective of the adolescent with lived experience of NSSI in a joint conceptualization of NSSI and treatment focus.

Abstract
Abstract
Background
Primary acute heart failure (AHF) is an established and common cause of hospitalization. AHF may also develop secondarily, e.g. postoperatively (pAHF). Little is known about pAHF.
Purpose
To assess the incidence, phenotypes, determinants and outcomes of pAHF following non-cardiac surgery.
Methods
We prospectively included 9,164 consecutive patients at high cardiovascular risk undergoing 11,262 non-cardiac surgeries. The incidence, phenotypes, determinants and outcome of pAHF, centrally adjudicated by independent cardiologists, was determined. Logistic regression models identified the risk factors for pAHF. Cox regression analysis compared mortality and AHF readmission within 1 year in patients with and without pAHF. External validation was performed using a prospective cohort multicenter study of 1250 patients.
Results
The incidence of pAHF was 2.5% (95% confidence interval [CI] 2.2–2.8%). pAHF most often occurred on postoperative day 2 (median day 4). About half of pAHF (51%) occurred in patients without known HF (de novo pAHF), and 49% in patients with chronic HF. Preserved left ventricular ejection fraction (LVEF) was the dominant phenotype among de novo pAHF (72%), while reduced LVEF was dominant among pAHF in chronic HF (43%). Age, coronary artery disease, peripheral artery disease, diabetes, urgent/emergent surgery, chronic HF, atrial fibrillation, chronic obstructive pulmonary disease, anemia, and chronic myocardial injury were independent predictors of pAHF. Patients with pAHF had significantly higher all-cause mortality (44% vs. 11%, p<0.001) and AHF readmission (15% vs. 2%, p<0.001) within 1 year than patients without pAHF. pAHF was an independent predictor of all-cause mortality (adjusted hazard ratio [aHR] 1.7 [95% CI 1.3–2.2]; P<0.001) and AHF readmission (aHR 2.7 [95% CI 1.7–4.2]; P<0.001) within 1 year. Findings were confirmed in an external validation cohort of 1250 patients, e.g. incidence of pAHF 2.4% (95% CI, 1.6–3.3%).
Conclusions
pAHF frequent developed following non-cardiac surgery, being de novo in about half of cases, and associated with an unacceptable high mortality. Strategies focusing on early detection and treatment of pAHF seem warranted.

Abstract
Abstract
Background
Current ESC guidelines on management of acute myocardial infarction in patients presenting with ST-segment elevation (STEMI) recommend emergent invasive management in patients with ischemic symptoms and bundle branch block (BBB). While left bundle branch block (LBBB) is a well-known high-risk feature in patients with acute myocardial infarction, data on the diagnostic and prognostic impact of right bundle branch block (RBBB) in comparison to LBBB in the context of STEMI are scarce.
Methods
A prospective cohort of 2,139 patients with suspected STEMI were triaged by the on-call cardiologist to acute coronary angiography based on a prehospital, tele-transmitted digital 12-lead electrocardiogram. All discharge diagnoses were independently adjudicated. The diagnostic accuracy of RBBB or LBBB was calculated. 30-day and 1-year all-cause mortality were from a central national registry and compared for LBBB, RBBB and patients without BBB using the Kaplan Meier method. Unadjusted and adjusted (age, sex, hypertension, hyperlipoproteinemia, smoking status and history of coronary artery disease) hazard ratios for 1-year mortality were calculated for both BBB-types.
Results
The final diagnosis of STEMI was adjudicated in 1,832/2,139 (85.6%) of patients. RBBB was present in 117 (5.5%), LBBB in 61 (2.9%) patients, respectively. Patients with BBB were older than non-BBB patients: Median age was 69.7 years in RBBB, 68.9 years in LBBB and 62.6 years in non-BBB patients. Comparing both BBB types, LBBB patients more often had prior heart failure (6.3% in RBBB vs 11.5% in LBBB), while RBBB patients more often developed cardiac arrest before angiography (15.3% vs 3.7% in RBBB and LBBB patients respectively) and more frequently revealed Thrombolysis in Myocardial Infarction (TIMI) grade flow of 0 (61.0% vs 47.2%, respectively).
Specificity for the final diagnosis of STEMI was not significantly different in both BBB-types: 95.1% (95% CI 92.1–97.0) in RBBB versus 92.8% (95% CI 89.4–95.2) in LBBB patients (p=0.25).
Patients with RBBB had significantly higher 30-day and 1-year mortality (Figure 1), while LBBB and non-BBB patients showed similar outcome. Unadjusted hazard ratio for 1-year mortality comparing RBBB to non-BBB patients was 3.35 (95% CI 2.11–5.34, p<0.001) and 1.4 (95% CI 0.57–3.44, p=0.46) when comparing LBBB to non-BBB patients. After adjustment hazard ratio for RBBB patients was 2.3 (95% CI 1.25–4.21, p=0.007).
Conclusion
In the context of suspected STEMI, RBBB is an ominous sign associated with adverse clinical features like cardiac arrest prior to PCI, TIMI grade 0 flow, compared to LBBB or non-BBB presenters. Consequently, RBBB patients had poorer outcome after 12 months. Our data therefore reinforce current guidelines in designating RBBB-patients as very high-risk, demanding immediate management and triage.

Abstract
Background Nonsuicidal self-injury (NSSI) is common in adolescents. Emotion dysregulation has been identified as a core mechanism in the development and maintenance of NSSI and it is therefore an important target when addressing NSSI. The pathogenic connection between different kinds of childhood abuse, difficulties in emotion regulation and NSSI needs further investigation. The objective of this study was to examine whether difficulties with emotion regulation and trauma symptoms, separately and together, mediate the relationships between sexual, physical and emotional abuse and NSSI. Method Cross-sectional data was collected from 3,169 adolescent high-school students aged 16-19 years (M = 18.12, SD = 0.45). Data from self-reported experiences of childhood abuse, current difficulties with emotion regulation (measured with the Difficulties with Emotion Regulation Scale, DERS-16) and trauma symptoms (measured with the Trauma Symptom Checklist for Children, TSCC), and NSSI were collected. Structural Equation Modeling (SEM) was used to test the proposed relationships between variables. Results The prevalence of life-time NSSI was 27.4%. Prevalence of reported childhood abuse was 9.2, 17.5, and 18.0% for sexual, physical, and emotional abuse, respectively. Childhood abuse, difficulties with emotion regulation and trauma symptoms exhibited significant positive associations with NSSI in adolescents. Emotional dysregulation and trauma symptoms were both found to mediate the relationship between childhood abuse and NSSI. Latent variable models were found to fit data well. Conclusion Results indicate that increased levels of emotional dysregulation and trauma symptoms in relation to childhood abuse contribute to the increased risk of NSSI. Further, results point to some aspects of emotional dysregulation and trauma symptoms being more important in this regard. Clinical implications are discussed.

Abstract
BackgroundInterstitial lung disease (ILD) in primary Sjögren’s syndrome (pSS) has been reported to be present in 10-15% of patients, but pSS-ILD behavior over time is not well characterized.ObjectivesAssess the pattern of ILD in pSS, its disease behavior and factors associated with disease progression in a well-characterized pSS-ILD cohort.MethodsAll pSS patients from the Oslo University Hospital (OUH) were included if ILD was diagnosed on HRCT. Clinical characteristics, lung function tests including forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO) and ILD pattern on HRCT assessed by a radiologist were evaluated. We determined ILD progression, defined as absolute FVC decline >5% or absolute DLCO decline >10% over 12 +/-6 months and increasing extent of ILD on HRCT over the observation period. Factors associated with disease progression were chosen based on expert opinion. Descriptive analyses were conductedResultsOf 702 pSS patients followed at OUH, we identified 60 pSS patients with ILD with 33 (55%) having follow-up at 12 months (Table 1). Patients with pSS-ILD were characterized by high number of males (18%) and by frequent other extra-pulmonary organ involvement (48%) (Table 1). Mean time from pSS diagnosis to ILD diagnosis was 7.4 years. In 67% ILD was diagnosed after pSS, in 13% simultaneously, in 11% before pSS diagnosis and in 9% unknown. In total, 28 (47%) were diagnosed with lymphocytic interstitial pneumonia (LIP) and 32 (53%) with reticular pattern on HRCT. Over mean follow-up of 10.9 months (SD 4.2), 7/33 (21%) showed a FVC >5% decline, 9/32 (28%) a DLCO >10% decline and 12 (36%) had at least one of these defined lung function declines on standard of care treatment. Treatment was registered as ever used and by any indication. Over an observation period of 15.4 (SD 10.6) years, 27/47 (45%) showed any ILD progression on HRCT. HRCT pattern was not associated with risk of >10% DLCO decline or ILD progression on HCRT. >5% FVC decline occurred more frequently in patients with reticular pattern compared to LIP (6/17 (35%) vs 1/16 (6%), p=0.041). Factors significantly associated with ILD progression on lung function included higher baseline FVC (99% (SD16.4) vs 87% (SD14.9), p=0.032), higher DLCO (81% (SD13.1) vs 67% (SD17.4), p=0.020), increased CRP (2/10 (20%) vs 0/16 (0%), p=0.045) and presence of polyneuropathy (2/9 (22%) vs 1/17 (6%), p=0.045).Table 1.Clinical characteristics, demographics and outcome of pSS with ILDpSS-ILD(n=60)Age at pSS diagnosis, y (SD)50 (21.9)Time from pSS to ILD diagnosis, y (SD)7.4 (8.9)Male sex, n (%)11 (18)Anti-SSA AB, n/50 (%)46 (92)Increased CRP, n/47 (%)7 (15)Low complements, n/49 (%)5 (10)Extra-pulmonary involvement, n/46 (%)22 (48)Deceased, n (%)10 (17)Pulmonary involvementFVC% predicted (SD)91 (18.7)FVC decline>5%, n/33 (%)7 (21)DLCO% predicted (SD)70 (20.7)DLCO decline >10%, n/32 (%)9 (32)ILD progression on HRCT, n/47 (%)27 (45)Treatment during follow upRituximab, n (%)11 (18)Any other immunosuppressive, n (%)20 (33)Hydroxychloroquine, n (%)16 (27)Nintedanib, n (%)1 (2)Lung transplant, n (%)1 (2)ConclusionA substantial number of patients with pSS-ILD progressed during the time of observation.

Abstract
BackgroundTakayasu arteritis (TAK) is a rare vasculitis of large vessels, mainly in young women, with a point prevalence of 25.6/106 in a Norwegian population. TAK is most prevalently limited to the aortic arch and its branches (Type 1) among North Europeans (1). Early symptoms include fever, myalgia and loss of appetite. Later, irreversible vascular damage and ischemic symptoms with claudication of the extremities may occur. We have previously observed a reduced life expectancy, mainly due to cardiovascular complications and a median age among those deceased of only 58 years (2). These findings clearly indicate that TAK may have severe impact on the wellbeing of the patients and their physical capacity. Furthermore, being part of the working life is a major component of life but is affected in chronic autoimmune diseases (3,4)Objectives(i) To describe general health status and quality of life in patients with different working status.(ii) To estimate the rates of patients having paid work or receiving disability benefits, compared to the general Norwegian population.MethodsPatients with TAK registered in “The Norwegian Systemic Connective Tissue Disease and Vasculitis Registry” (NOSVAR) were included. All patients fulfilled the American College of Rheumatology classification criteria and/or the modified Ishikawa diagnostic criteria for TAK. (3). General health status was measured with 10-cm visual analogue scale (VAS) of pain and fatigue, ranging from 0 (best possible score) to 10 (worst possible score) and with Patients´ global assessment (PtGA) of health measured by a five-point Likert scale with scores ranging from 1 (very good health) to 5 (very bad health). The SF-36 was applied to measure health related quality of life and included 8 scales with score ranging from 0 (worse) to 100 (best). Disease duration was defined as the time from diagnosis to date of registration. Working full- or part time was defined as paid work. We adjusted for age, gender and residence counties in southeast Norway using reference data from Norway Statistics. Indirect standardization with 95% confidence interval rates was calculated. Descriptive analyses were conducted.ResultsPatients with paid work were more educated compared with those receiving disability benefits (81% vs 19% p=0.031). Patients receiving disability benefits reported higher levels of pain (3,4 vs.1,4, p=0.024) and disease activity (3,8 vs. 0,8, p=0.025), more frequently claudication in legs (83% vs. 17%, p= 0.009) and impaired quality of life measured with SF- 36, physical functioning (66 vs 88, p=0.002) and role physical (32 vs 65, p=0.017) compared to patients with paid work/students (Figure 1).Compared with the age and gender matched general population, the disability rate of female patients was 16 % higher, adjusted ratio (CI 95%) 2 (1,2-3,3), p=0.038. The paid work rate was 51% lower in women with TAK compared to the general population, adjusted ratio (CI 95%) 0,38 (0,23-0,64), p=0.001 .ConclusionTAK-patients receiving disability benefits reported lower health status and lower quality of life by physical functioning and role physical in SF 36. Work disability in female TAK patients was 16 % higher and for paid work 51 % lower compared to the general population.References[1]Gudbrandsson B, Molberg Ø, Garen T, Palm Ø, Arthritis Care Resb (Hoboken), 2017 Sept;69:1384-1390[2]Garen T, Lerang K, Hoffmann-Vold AM, Andersson H, Midtvedt Ø, Brunborg C, Kilian K, Gudbrandsson B, Gunnarsson R, Norby G, Chaudhary A, Thoen J, Forseth KØ, Fresjar K, Førre Ø, Haugen M, Haga HJ, Gran JT, Gilboe IM, Molberg Ø, Palm Ø.

Abstract
BackgroundThere is a gap between how IIM patients are classified in practice and current validated classification criteria1. Also, different associations with genetic variations in HLA can inform about different T-cell mechanisms involved in disease pathogenesis.ObjectivesWe aimed to systematically study associations between HLA-DRB1 alleles, clinical manifestations, and autoantibody-defined IIM subgroups.MethodsWe included 1348 IIM patients from five European countries. An unsupervised cluster analysis was performed using 14 autoantibodies: anti-Jo1, -PL7, -PL12, -EJ, -OJ, -SRP, -U1RNP, -Ro52, -Mi2, -TIF1γ, -MDA5, -PMScl, -SAE1, and -NXP2 to identify patients’ subgroups. Logistic regressions were used to estimate the associations between HLA-DRB1 alleles, clinical manifestations and the identified subgroups.ResultsEight subgroups were defined by the autoantibody status (Table 1). Three of the subgroups (1, 2 and 6) have overlapping autoantibodies, while four are almost monospecific (3,4,5 and 7), and one (8) has patients negative for tested autoantibodies. Figure 1 represents the significant associations between HLA-DRB1 alleles and the eight subgroups. Heliotrope rash and Gottron’s sign were significantly more frequent in subgroups 3 (OR:2.2 95%CI:[1.1-4.8], OR:2.6 95%CI:[1.3-5.9], respectively), 4 (OR:12 95%CI:[3.6-75], OR:7.8 95%CI:[2.8-33], respectively) and 7 (OR:22 95%CI:[4.5-385], OR:10 95%CI:[3.1-65], respectively), and Raynaud’s phenomenon was significantly more frequent in subgroup 6 (OR:3.3 95%CI:[1.2-11]).Table 1.Autoantibody-defined subgroups using an unsupervised cluster analysis.Subgroups/ MedoidsVariables1 Ro522 U1RNP3 PMScl4 Mi25 Jo16 Jo1/Ro527 TIF18 None*Alln (%)137 (10)183 (14)107 (8)65 (5)119 (9)140 (10)78 (6)519 (39)1348 (100)Female (%)93 (68)116 (63)79 (74)45 (69)76 (64)96 (69)64 (82)313 (60)882 (65)Age at diagnosis, median (IQR)56 (16)51.5 (23)51 (25)57 (22.5)47.5 (23.25)52 (19.5)53.5 (21.75)58 (22)55 (23)AutoantibodiesAnti-Jo106 (3)01 (2)119 (100)140 (100)00266 (20)Anti-PL77 (5)13 (7)00000020 (1.5)Anti-PL125 (4)3 (2)1 (1)01 (1)00010 (0.7)Anti-EJ2 (2)00000002 (0.1)Anti-OJ07 (4)0000007 (0.5)Anti-TIF110 (7)2 (1)2 (2)00078 (100)092 (7)Anti-Mi21 (1)1 (1)1 (1)65 (100)02 (1)0070 (5)Anti-SAE18 (6)23 (13)00000031 (2)Anti-NXP21 (1)23 (13)1 (1)0000025 (2)Anti-MDA59 (7)10 (6)1 (1)1 (2)01 (1)0022 (2)Anti-SRP8 (6)32 (18)00000040 (3)Anti-Ro52137 (100)16 (9)000140 (100)00293 (22)Anti-PMScl11 (8)1 (1)107 (100)00000119 (9)Anti-U1RNP079 (43)0003 (2)0082 (6)*IIM patients negative for the tested autoantibodies.Figure 1.Forest plot of significant associations of HLA. *DRB1 alleles with autoantibody-defined subgroups.

These results point to different disease mechanisms in the subgroups, as well as suggest that IIM classification could be improved by integrating broader serological and genetic data.References[1]Parker MJS, Oldroyd A, Roberts ME, et al.

Abstract
BACKGROUND Early and correct diagnosis of ST-segment elevation myocardial infarction (STEMI) is crucial for providing timely reperfusion therapy. Patients with ischemic symptoms presenting with ST-segment elevation on the electrocardiogram (ECG) are preferably transported directly to a catheterization laboratory (Cath-lab) for primary percutaneous coronary intervention (PPCI). However, the ECG often contains confounding factors making the STEMI diagnosis challenging leading to false positive Cath-lab activation. The objective of this study was to test the performance of a standard automated algorithm against an additional high specificity setting developed for reducing the false positive STEMI calls. METHODS We included consecutive patients with an available digital prehospital ECG triaged directly to Cath-lab for acute coronary angiography between 2009 and 2012. An adjudicated discharge diagnosis of STEMI or no myocardial infarction (no-MI) was assigned for each patient. The new automatic algorithm contains a feature to reduce false positive STEMI interpretation. The STEMI performance with the standard setting (STD) and the high specificity setting (HiSpec) was tested against the adjudicated discharge diagnosis in a retrospective manner. RESULTS In total, 2256 patients with an available digital prehospital ECG (mean age 63 ± 13 years, male gender 71%) were included in the analysis. The discharge diagnosis of STEMI was assigned in 1885 (84%) patients. The STD identified 165 true negative and 1457 true positive (206 false positive and 428 false negative) cases (77.3%, 44.5%, 87.6% and 17.3% for sensitivity, specificity, PPV and NPV, respectively). The HiSpec identified 191 true negative and 1316 true positive (180 false positive and 569 false negative) cases (69.8%, 51.5%, 88.0% and 25.1% for sensitivity, specificity, PPV and NPV, respectively). From STD to HiSpec, false positive cases were reduced by 26 (12,6%), but false negative results were increased by 33%. CONCLUSIONS Implementing an automated ECG algorithm with a high specificity setting was able to reduce the number of false positive STEMI cases. However, the predictive values for both positive and negative STEMI identification were moderate in this highly selected STEMI population. Finally, due the reduced sensitivity/increased false negatives, a negative AMI statement should not be solely based on the automated ECG statement.

Abstract
Background:Based on the argument that symptoms define disease, physicians commonly apply the terms “preclinical” or “subclinical” disease to describe patients with disease-related findings but no accompanying symptoms for connective tissue disease associated interstitial lung disease (CTD-ILD). The term subclinical frequently applies to patients with mild ILD changes on high resolution chest tomography (HRCT), normal forced vital capacity (FVC), and without respiratory symptoms. Previous work in systemic sclerosis (SSc)-ILD did show that patients with even minor extent of ILD at baseline often progressed and had increased mortality risk, suggesting that it is not appropriate to define these patients as “subclinical.”Objectives:To identify the prevalence of subclinical ILD across CTD diagnoses, and assess the rate of progression of lung fibrosis compared to CTD without ILD and with clinical ILD.Methods:All CTD patients, including SSc, anti-synthetase syndrome (ASS) and mixed connective tissue disease (MCTD) from the Oslo University Hospital diagnosed before 2015 and assessed for the presence of ILD by HRCT were included. The year 2015 was chosen to secure an observation time of at least five years from ILD diagnosis to study end on 01.01.2021 or time of death. All patients fulfilled the respective CTD classification criteria. Subclinical ILD was defined as an ILD extent <5% by semi-quantitative assessment of baseline HRCT, preserved lung function with FVC >80% predicted and without respiratory symptoms. Clinical ILD was defined as >5% extent of ILD or <5% extent of ILD on HRCT with respiratory symtoms or FVC<80%. The outcome was ILD progression, defined as increasing extent of ILD from basline to follow-up HRCT by semi-quantitative assessment. Vital status was available in all patients and mortality was evaluated. Descriptive statistical analyses were conducted and time to ILD progression determined by Kaplan-Meier estimates.Results:We identified 525 CTD patients, including 296 with SSc, 135 with MCTD and 94 with ASS who had conducted a baseline HRCT. Of these, 227 (43%) had no ILD, 67 (13%) subclinical and 231 (44%) clinical ILD (Table). Of the 67 subclinical ILD patients, 45 (15%) had SSc, 13 (10%) MCTD and 9 (10%) ASS of thespecific cohorts. Over a median time of 4.5 years between baseline and follow-up HRCT, 95/395 (24%) showed progression of ILD, including 72 (26%) SSc and 23 (19%) MCTD patients. Disease progression frequently occurred in both subclinical ILD (38%) and clinical ILD (51%) patients (Figure). Age, gender, underlying CTD, and baseline lung function were not predictive for the progression of lung fibrosis. Progression was too infrequent to allow for meaningful multivariable regression analyses. After a median observation period of 12 years, 153 (29%) of the patients died. The 1-, 5- and 10-year survival rates in those without ILD, subclinical and clinical ILD were 97%/97%/99%, 88%/91%/82%, and 82%/85%/68% (p<0.001), respectively.Table 1.Clinical characteristics, demographics and outcomeNo ILD (n=227)Subclinical ILD (n=67)Clinical ILD (n=231)Age, y (SD)50 (15.4)51 (14.4)52 (15.3)Male sex, n (%)89 (39)22 (33)111 (48)Deceased, n (%)50 (22)12 (18)91 (39)Observation period, y median (range)13.7 (18.6)13.9 (17.9)11.5 (17.1)FVC% (SD)97 (18.6)99 (17.9)81 (20.9)FVC decline% (SD)-0.70 (11.1)-0.81 (16.5)-1.61 (15.9)DLCO% (SD)73 (19.4)73 (16.9)55 (17.4)Extent of ILD% (SD)0 (0)2.3 (1.5)19.3 (16.8)ILD progression% (SD)0.08 (1.0)3.1 (6.2)3.6 (9.9)ILD progressors, n (%)3 (2)20 (38)72 (51)Figure 1.Time to ILD progression in CTD without ILD, with subclinical and clinical ILDConclusion:Subclinical ILD is frequently present across CTDs and progresses over time in a substantial subgroup of patients, comparable to patients with clinical ILD. Our findings question the terms sub- and preclinical ILD, which may potentially lead to a suboptimal “watchful waiting management strategy”. Monitoring all CTD patients with any ILD is of high importance to identify disease progression early.Disclosure of Interests:Anna-Maria Hoffmann-Vold Speakers bureau: Actelion, Boehringer Ingelheim, Roche, Merck Sharp & Dohme, Lilly and Medscape, Consultant of: Actelion, Boehringer Ingelheim, Bayer, ARXX, and Medscape, Grant/research support from: Boehringer Ingelheim, Helena Andersson: None declared, Silje Reiseter: None declared, Håvard Fretheim Consultant of: Actelion, Bayer., Imon Barua: None declared, Torhild Garen: None declared, Øyvind Midtvedt: None declared, Ragnar Gunnarsson: None declared, Mike Durheim Speakers bureau: Boehringer Ingelheim and Roche, Consultant of: Boehringer Ingelheim, Grant/research support from: Boehringer Ingelheim, Trond M Aaløkken: None declared, Øyvind Molberg: None declared

Abstract
Background:Adult-onset Still’s disease (AOSD) and systemic juvenile idiopathic arthritis (SJIA) are rare autoinflammatory disorders associated with an activated IL-1 pathway, characterized by spiking fever, rash, arthritis, lymphadenopathy, hepatosplenomegaly and serositis. There is a growing understanding that SJIA and AOSD are one disease with different ages of onset, i.e. Still’s disease. The anaSTILLs study (anakinra inStill´sdisease) was designed to further evaluate efficacy and safety of anakinra in patients with Still´s disease across all age groups.Objectives:The primary objective was to demonstrate efficacy of anakinra versus placebo as assessed by ACR30 response with absence of fever at Week 2. Secondary objectives included: early onset of efficacy, sustained efficacy, time to study drug discontinuation, safety, pharmacokinetics, clinical signs and biomarkers.Methods:‘anaSTILLs’ was a randomized, double-blind, placebo-controlled, 12-week study including patients with active and newly diagnosed (6 months) Still´s disease according to adapted ILAR criteria if <16, or Yamaguchi criteria, if ≥16 years of age at disease onset. Patients were randomized to anakinra 2 mg/kg (max 100 mg/day), 4 mg/kg (max 200 mg/day) or placebo.Results:12 patients were randomized and received study drug: 6 anakinra (2 mg/kg n=2, 4 mg/kg n=4) and 6 placebo, the study was terminated early due to slow recruitment. 1 patient on placebo had lymphoma, not Still’s disease, and was excluded; thus in total 11 patients were analyzed for efficacy, 8 were children [median (range) age=4.0 (1-11) years] and 3 were adults [median (range) age=32.0 (25-51) years]. 55% were male and the mean symptom duration was 74.2 days. All patients on anakinra but none on placebo achieved ACR30 response with absence of fever at Week 2 (p-value=0.0022). The efficacy of anakinra was further demonstrated by superiority to placebo in ACR50/70/90 responses with absence of fever at Week 2. All placebo patients discontinued the study within 6 weeks, 2 due to progressive disease, 2 due to lack of efficacy and 1 due to withdrawal by patient. There was a numerically higher proportion with early onset of efficacy (Week 1) in the anakinra group compared to placebo. The ACR30/50/70/90 responses in the anakinra group were sustained throughout the study period. Patients in the anakinra group had a prompt and persistent decrease in CRP and ferritin levels at Week 1, which was not observed in the placebo group. There were no unexpected safety findings. All anakinra patients developed anti-drug antibodies (ADAs) at some timepoint during the study. ADAs were persistent throughout the treatment period, except in one patient. Titers were low to moderate. One placebo patient had low ADA titers at one occasion. No neutralizing antibodies were observed and the ADAs did not appear to impact clinical efficacy or safety.Conclusion:Anakinra is superior to placebo in the treatment of Still’s disease. ADAs occur frequently but do not appear to adversely impact efficacy or safety. These results confirm the benefits of anakinra treatment in patients with active, newly diagnosed Still´s disease across ages.Disclosure of Interests:Laura Schanberg Grant/research support from: Sobi, BMS, Consultant of: Aurinia, UCB, Sanofi, Peter Nigrovic Grant/research support from: Novartis, BMS, Pfizer, Consultant of: Novartis, BMS, Pfizer, Sobi, Miach Orthopedics, Simcere, XBiotech, Quench Bio, Ashley Cooper: None declared, Winn Chatham Grant/research support from: Sobi, Consultant of: Sobi, Shoghik Akoghlanian: None declared, Namrata Singh: None declared, Egla Rabinovich Grant/research support from: AbbVie, UCB Pharma, Janssen Research & Development, Akaluck Thatayatikom: None declared, Alysha Taxter: None declared, Jonathan Hausmann Consultant of: Novartis, Milan Zdravkovic Shareholder of: Sobi, Employee of: Sobi, Sven Ohlman Shareholder of: Sobi, Employee of: Former employee of Sobi, Henrik Andersson Employee of: Sobi, Susanna Cederholm Shareholder of: Sobi, Employee of: Sobi, Margareta Wikén Shareholder of: Sobi, Employee of: Former employee of Sobi, Rayfel Schneider Grant/research support from: Roche, Novartis, Sobi, Pfizer, Consultant of: Sobi, Novartis, Novimmune, Fabrizio De Benedetti Grant/research support from: AbbVie, Pfizer, Novartis, Novimmune, Sobi, Sanofi, Roche, Speakers bureau: AbbVie, Novartis, Roche, Sobi

Abstract
Abstract
Background
Patients with suspected ST-elevation myocardial infarction (STEMI) and normal coronary arteries comprise a heterogeneous group with various underlying causes of disease.
Purpose
To study pathophysiology and underlying diagnoses in patients with suspected STEMI and normal coronary arteries using multimodal cardiac imaging.
Methods
We consecutively included patients with suspected STEMI, normal coronary arteries on acute coronary angiography, and elevated troponin T levels at a tertiary heart center (2012–14). Patients were examined with echocardiography, cardiac magnetic resonance imaging, and 13NH3/82Rb and 18F-FDG positron emission tomography within one week from symptom onset.
Results
We included 42 patients (60% male, median age 58 (IQR 50–65) years. Median troponin T levels were 783 (IQR 566–1208) ng/l. Multimodal cardiac imaging findings are presented in Table 1. Multimodal cardiac imaging showed signs of cardiac involvement in all but one patient (98%). Underlying diagnoses were acute myocardial infarction (36%), Takotsubo cardiomyopathy (29%), perimyocarditis (10%), and cardiomyopathy (7%). The diagnosis was unclear in 19% of patients.
Echocardiography Left ventricular ejection fraction <40%, n (%) 12 (29) Moderate to severe left ventricular hypertrophy, n (%) 3 (7) Moderate to severe valvular disease, n (%) 3 (7) Pericardial effusion, n (%) 5 (12) Apical thrombus, n (%) 1 (2) Magnetic resonance imaging Left ventricular end diastolic volume, ml (IQR) 157 (125–185) Left ventricular end systolic volume, ml (IQR) 75 (63–88) Left ventricular stroke volume, ml (IQR) 73 (57–93) Edema, n (%) 38 (91) Late gadolinium enhancement, n (%) 22 (52) 13NH3/82Rb and 18F-FDG positron emission computer tomography Myocardial perfusion defect, n (%) 29 (69) Myocardial perfusion-metabolism mismatch, n (%) 12/30 (40) Reduced myocardial viability, n (%) 6/30 (20)
Conclusion
The majority of patients with suspected STEMI and normal coronary arteries had signs of cardiac involvement by multimodal cardiac imaging and were diagnosed with cardiac disease.

Abstract
Abstract
Background
Patients with suspected ST-elevation myocardial infarction (STEMI) and no obstructive coronary artery disease (CAD) comprise a heterogeneous group with varying prognoses.
Purpose
To evaluate the prognostic value of cardiac troponin T (cTnT) in patients with suspected STEMI and no obstructive CAD.
Methods
Patients with suspected STEMI and no obstructive (<50% diameter stenosis) CAD were consecutively included from 2009–2014. Patients were classified as having normal cTnT, dynamic cTnT elevation, or stationary cTnT elevation. All patients were followed with respect to major adverse cardiovascular events (MACE), cardiovascular readmission, and repeat coronary procedures, until 1 year after discharge.
Results
The study included 502 patients with suspected STEMI and no obstructive CAD: 165 (33%) had normal cTnT, 293 (58%) had dynamic cTnT elevation and 44 (9%) had stationary cTnT elevation. Within one year after admission, 40 (8%) had MACE, 81 (16%) had cardiovascular readmission, and 8 (2%) underwent repeat coronary procedures. The risk of MACE was elevated in patients with stationary cTnT elevation compared with normal cTnT (OR 13.6, 95% CI 2.3–80.2, p=0.004). There was no statistically significant difference between those with dynamic cTnT elevation and normal cTnT (OR 2.9, 95% CI 0.6–14.0, p=0.189). Adding cTnT pattern to a conventional risk model, area under the receiver operating curve for predicting the 1-year risk of MACE improved significantly (80% vs. 85%, p=0.004, Figure 1).
Figure 1
Conclusion
In patients with suspected STEMI and no obstructive CAD, cTnT pattern during acute hospitalization is associated with the 1-year risk of MACE and improves risk prediction for the individual patient.

Abstract
The promotion of students’ engagement with school is an internationally acknowledged challenge in education. There is a need to examine the structure of the concept of student engagement and to discover the best practices for fostering it across societies. That is why the cross-cultural invariance testing of students’ engagement measures is highly needed. This study aimed, first, to find the reduced set of theoretically valid items to represent students’ affective and cognitive engagement forming the Brief-SEI (brief version of the Student Engagement Instrument; SEI). The second aim was to test the measurement invariance of the Brief-SEI across three countries (Denmark, Finland, and Portugal). A total of 4,437 seventh-grade students completed the SEI questionnaires in the three countries. The analyses revealed that of the total 33 original instrument items, 15 items indicated acceptable psychometric properties of the Brief-SEI. With these 15 items, cross-national factorial validity and invariances across genders and students with different levels of academic performance (samples from Finland and Portugal) were demonstrated. This article discusses the utility of the Brief-SEI in cross-cultural research and its applicability in different national school contexts.

Abstract
This is the first trial to investigate the outcome of tailored and ACT-influenced, cognitive behavioral Internet treatment for eating disorder psychopathology, and the relation between knowledge acquisition and outcome. This study utilized a randomized controlled design, with computer-based allocation to treatment or waiting list control group. Participants were recruited via advertisements in social media and newspapers in Sweden. Participants fulfilling the criteria for bulimia nervosa (BN), or Eating Disorder Not Otherwise Specified (EDNOS), with a BMI above 17.5, were enrolled in the study (N = 92). The treatment group received an Internet-based, ACT-influenced CBT intervention, developed by the authors, for eating disorders. The treatment lasted 8 weeks, and was adapted to the participant's individual needs. A clinician provided support. The main outcome measures were eating disorder symptoms and body shape dissatisfaction. Intent-to-treat analysis showed that the treatment group (n = 46) improved significantly on eating disorder symptoms and body dissatisfaction, compared with the waiting list control group (n = 46), with small to moderate effect sizes (between group effects, d = 0.35-0.64). More than a third of the participants in the treatment group (36.6%), compared to 7.1% in the waiting list control condition, made clinically significant improvements. Results showed a significant increase in knowledge in the treatment group compared to the waiting list control group (between group effect, d = 1.12), but we found no significant correlations between knowledge acquisition and outcome (r= -0.27 to -r = 0.23). The results provide preliminary support for Internet-based, tailored, and ACT-influenced treatment, based on CBT for participants with eating disorder psychopathology.

Abstract
BACKGROUND We previously reported that exposure to a farming environment is allergy-protective, while high proportions of neonatal immature/naïve CD5+ B cells and putative regulatory T cells (Tregs) are risk factors for development of allergic disease and sensitization up to 3 years of age. OBJECTIVE To examine if B and T cell maturation are associated with allergic disease and farming environment over the first 8 years in life. METHODS In the prospective FARMFLORA study, including both farming and non-farming families, 48 of 65 children took part in the 8-year follow-up study. Various B and T cell maturation variables were examined in blood samples obtained at several occasions from birth to 8 years of age and related to doctors' diagnosed allergic disease and sensitization, and to farming environment. RESULTS We found that the incidence of allergic disease was lower among farmers' compared to non-farmers' children during the 8-year follow-up period, and that farmers' children had higher proportions of memory B cells at 8 years of age. Moreover, a high proportion of neonatal CD5+ B cells was a risk factor for and may predict development of allergic disease at 8 years of age. A high proportion of Tregs was not protective against development of these conditions. CONCLUSION AND CLINICAL RELEVANCE High proportions of neonatal naïve B cells remained as a risk factor for allergic disease in school-aged children. Thus, the accelerated B cell maturation observed among farmers' children may be crucial for the allergy-protective effect of a farming environment.

Abstract
The aim of this study was to examine the effect of carbohydrate mouth rinse on 30-min arm cranking performance. Twelve healthy, active males (age 21.6, standard deviation (SD)=3.1 years; mass 76.2, SD=12.2 kg) volunteered in a single-blind, randomised crossover design. Firstly they completed an incremental exercise test to exhaustion (VO2max test) on an arm crank (50W for 2 min, increasing by 10W every min). During visit 2 and 3 they arm cranked for maximal distance over 30 min at a resistance equivalent to 50% of their peak power, mouth rinsing for 5 s with either 25 ml of a tasteless 6.4% maltodextrin solution (CHO) or 25 ml of water (placebo) every 6 min. A letter cancellation test was performed pre and post exercise to measure cognitive function. The result showed that cognitive function was not significantly different between trials (P=0.874). There was no significant difference in distance arm cranked between trials (P=0.164) even though 9 out of 12 participants had improved performance on the CHO trial. In conclusion, further research is needed to determine the ergogenic effect of CHO mouth rinsing on upper body exercise performance.

Abstract
BACKGROUND Methicillin-resistant Staphylococcus aureus is a resistant variant of S. aureus and can cause pneumonia, septicaemia and, in some cases, death. Caring for patients with antibiotic resistant bacteria is a challenge for healthcare personnel. There is a risk of spreading the bacteria among patients and of healthcare personnel being infected themselves. AIM To describe nursing staffs' experiences of caring for patients with methicillin-resistant S. aureus in Sweden. METHOD A descriptive qualitative approach was used and 15 nurses from different hospitals and care units, including emergency and geriatric wards and nursing homes in Stockholm, were interviewed. All nurses had been involved in the care of patients with methicillin-resistant S. aureus, but not on a regular basis. The interviews were analysed using qualitative content analysis. FINDINGS Three themes emerged from the data: feeling ignorant, afraid and insecure, feeling competent and secure and feeling stressed and overworked. The more knowledge the nurses acquired about methicillin-resistant S. aureus, the more positive was their attitude to caring for these patients. DISCUSSION AND CONCLUSION Caring for patients with methicillin-resistant S. aureus without adequate knowledge of how to protect oneself and other patients against transmission may provoke anxiety among personnel. Guidelines, memos and adequate information at the right time are of central importance. Healthcare personnel must feel safe in their role as caregivers. All patients have the right to have the same quality of care regardless of the diagnosis and a lack of knowledge influences the level of care given. IMPLICATIONS FOR NURSING AND HEALTH POLICY This study demonstrates the importance of education when caring for patients with infectious diseases. Hopefully, knowledge gained from our study can provide guidance for future health care when new diseases and infections occur.

Abstract
AIMS Takotsubo cardiomyopathy (TTC) is characterized by acute completely reversible regional left ventricle (LV) akinesia and decreased tracer uptake in the akinetic region on semi-quantitative perfusion imaging. The latter may be due to normoperfusion of the akinetic mid/apical area and basal hyperperfusion. Our aim was to examine abnormalities of perfusion in TTC, and we hypothesized that basal hyperperfusion is the primary perfusion abnormality in the acute state. METHOD AND RESULTS Twenty-five patients were diagnosed with TTC due to (i) acute onset of symptoms, (ii) typical apical ballooning, (iii) absence of significant coronary disease, and (iv) complete remission on 4-month follow-up. The patients underwent coronary angiography (CAG), echocardiography, cardiac magnetic resonance imaging (CMR), and (13)NH3/(82)Rb positron emission tomography (PET) in the acute state and-except CAG-on follow-up. Patients initially had severe heart failure, mid/apical oedema but no infarction, and a rise in cardiac biomarkers. On initial perfusion PET imaging, eight patients appeared to have normal, whereas 17 patients had impaired LV perfusion. In the latter, flow in the basal region was increased in the acute state (1.5 ± 0.1 vs. 1.2 ± 0.1 mL/g/minRPP-corrected, P < 0.01), whereas midventricular (1.7 ± 0.1 vs. 1.6 ± 0.1 mL/g/minRPP-corrected, P = 0.21) and apical (1.4 ± 0.1 vs. 1.5 ± 0.1 mL/g/minRPP-corrected, P = 0.36) flow was unchanged between acute and follow-up, and within normal range. CONCLUSION Our results suggest an abnormal LV perfusion distribution in the acute state of TTC with basal hyperperfusion and a normoperfused akinetic region. The proportion of patients without visualized perfusion abnormalities in the acute state may represent a subgroup with fast remission.

Abstract
AIMS Takotsubo cardiomyopathy (TTC) is an entity mimicking acute myocardial infarction, characterized by transient severe systolic heart failure. Echocardiographic studies suggest that diastolic dysfunction is present in TTC at presentation; however, no reports exist regarding the time course of left ventricular (LV) recovery. This study describes the recovery of LV systolic and diastolic function in TTC. We hypothesized that, in TTC, there is diastolic dysfunction at admission, and that recovery is delayed compared with systolic function. METHODS AND RESULTS We enrolled (consecutively 2010-12) 16 patients (mean age 66, range 39-84 years) diagnosed with TTC and 20 healthy matched controls. We performed cardiac magnetic resonance imaging (CMR) at admission, pre-discharge, and 3-month follow-up. Diastolic function was assessed by LV peak filling rate (LVPFR) and left atrial (LA) emptying volumes. At admission, LV ejection fraction was low, increased at pre-discharge (37 ± 6 vs. 58 ± 6%, P < 0.001), and normalized at follow-up (to 65 ± 5%, P = 0.01). LVPFR did not increase during hospitalization (80 ± 3 vs. 89 ± 4 mL/s/m(2), P = 0.21), but was normalized at follow-up (to 206 ± 19, P < 0.001; controls, 214 ± 13, P = 0.23). During hospitalization, LA passive emptying volume remained low (6 ± 2 vs. 8 ± 3 mL/m(2), P = 0.05) and LA active emptying volume remained high (17 ± 3 vs. 16 ± 3 mL/m(2), P = 0.71), whereas LA conduit volume increased (7 ± 3 vs. 23 ± 4 mL/m(2), P < 0.001). T2-weighted imaging demonstrated non-coronary distributed apical oedema without contrast enhancement. CONCLUSION Patients with TTC undergo fast systolic recovery. However, at discharge, profound diastolic dysfunction is demonstrated by CMR. At follow-up, both LV systolic and diastolic function is normalized in patients with recovered TTC.

Abstract
The resistance of inkjet printed lines using a silver nanoparticle based ink can be very dependent on the substrate. A very large difference in resistivity was observed for tracks printed on paper substrates with aluminum oxide based coatings compared to silica based coatings. Silica based coatings are often cationized with polymers using chloride as a counter ion. It is suggested that the precipitation of silver salts is the cause of the high resistivity, since papers pretreated with salt solutions containing ions that precipitate silver salts gave a high resistance. Silver nitrate has a high solubility and paper pretreated with nitrate ions gave a low resistivity without sintering. The results obtained show that, by choosing the correct type of paper substrate, it is possible to manufacture printed structures, such as interconnects on paper, without the need for, or at least to reduce the need for, post-print sintering. This phenomenon is, of course, ink specific. Inks without or with a low silver ion content are not expected to behave in this manner. In some sensor applications, a high resistivity is desired and, by using the correct combination of ink and paper, these types of sensors can be facilitated.

Abstract
In an open-label, multicenter trial, de novo kidney transplant recipients at low to medium immunological risk were randomized at week 7 posttransplant to remain on CsA (n = 100, controls) or convert to everolimus (n = 102), both with enteric-coated mycophenolate sodium and corticosteroids. The primary endpoint, change in measured GFR (mGFR) from week 7 to month 12, was significantly greater with everolimus than controls: 4.9 (11.8) mL/min versus 0.0 (12.9) mL/min (p = 0.012; analysis of covariance [ANCOVA]). Per protocol analysis demonstrated a more marked difference: an increase of 8.7 (11.2) mL/min with everolimus versus a decrease of 0.4 (12.0) mL/min in controls (p < 0.001; ANCOVA). There were no differences in graft or patient survival. The 12-month incidence of biopsy-proven acute rejection (BPAR) was 27.5% (n = 28) with everolimus and 11.0% (n = 11) in controls (p = 0.004). All but two episodes of BPAR in each group were mild. Adverse events occurred in 95.1% of everolimus patients and 90.0% controls (p = 0.19), with serious adverse events in 53.9% and 38.0%, respectively (p = 0.025). Discontinuation because of adverse events was more frequent with everolimus (25.5%) than controls (3.0%; p = 0.030). In conclusion, conversion from CsA to everolimus at week 7 after kidney transplantation was associated with a greater improvement in mGFR at month 12 versus CNI-treated controls but discontinuations and BPAR were more frequent.

Abstract
The fate of islets in clinical transplantation is unclear. To elude on this positron emission tomography combined with computed tomography (PET/CT) was performed for 60 min during islet transplantation in five patients receiving six transplants. A fraction of the islets (23%) were labeled with 18F-fluorodeoxyglucose ([(18)F]FDG) and carefully mixed with unlabeled islets just prior to intraportal transplantation. The peak radioactivity concentration in the liver was found at 19 min after start of islet infusion and corresponded to only 75% of what was expected, indicating that islets are lost during the transplantation procedure. No accumulation of radioactivity was found in the lungs. A nonphysiological peak of C-peptide was found in plasma during and immediately after transplantation in all subjects. Distribution in the liver was heterogeneous with wide variations in location and concentration. Islets found in areas with concentrations of >400 IEQ/cc liver tissue varied between 1% and 32% of the graft in different subjects. No side effects attributed to the PET/CT procedure were found. Clinical outcome in all patients was comparable to that previously observed indicating that the [(18)F]FDG labeling procedure did not harm the islets. The technique has potential to be used to assess approaches to enhance islet survival and engraftment in clinical transplantation.
