Abstract
Abstract
Background
Coronary microvascular disease (CMD) is a major contributor to e.g. heart failure and angina pectoris, as well as being associated with an increased risk of adverse events. CMD is diagnosed by reduced myocardial blood flow reserve (MBFR), preferably by Positron emission tomography myocardial perfusion CT (PET-CT).
Purpose
We aim to determine whether reduced MBFR is associated with an increased hazard of all-cause mortality independently of the extent of perfusion defects in patients suspected of obstructive coronary artery disease.
Method
We conducted a multicenter study of all patients referred for 82Rubidium PET-CT imaging between January 2018 and August 2020. Rest and stress examinations were performed using standard imaging protocols. Percentage of perfusion defects were calculated based on summed rest- and difference score. CMD was defined as MBFR ≤2. Patients were followed for all-cause mortality through national registries with no loss to follow-up.
Results
Among the 7156 patients studied, 61.8% were men, median age was 69 [61–76 IQR] years, 14.1% had LVEF ≤40%, 58.4% had a previous diagnosis of ischemic heart disease (IHD), 20.1% had atrial fibrillation and 38.9% had MBFR ≤2.
A total of 571 (7.8) deaths were observed, more frequently in MBFR ≤2 compared to MBFR >2 (4.2% vs 13.2%, p<0.001). MBFR was significantly associated with reversible hypoperfusion (r2=−0.33, p<0.0001). In Kaplan-Meier estimation MBFR ≤2 was significantly associated to all-cause mortality in the overall population as well as in clinically relevant subgroups defined by the extent of reversible and/or irreversible perfusion defects (p<0.05 for all, fig. 1). In multivariate Cox-analysis adjusting for age, sex, Charlson's Co-morbidity index, eGFR, LVEF and LVEF-reserve and stratifying by diabetes, MBFR ≤2 remained a robust predictor of all-cause mortality with a HR 1.73, 95% CI: 1.62–2.19, p<0.0001 (fig. 2). No interaction was found between MBFR and reversible hypoperfusion. In subgroup analysis including only patients with no reversible perfusion defects (n=3095), MBFR ≤2 was still strongly associated with a HR of 2.00, 95% CI: 1.29–3.11, p<0.001 for all-cause mortality.
Conclusion
MBFR ≤2 is a robust predictor of all-cause mortality independently of the extent of reversible- and/or irreversible perfusion defects. Information of MBFR should be incorporated in the clinical risk stratification of patients being investigated for ischemia.

Abstract
Abstract
Introduction
Guidelines recommend secondary ischemia assessment following a coronary computed tomography angiography (CTA) with suspected obstructive coronary artery disease (CAD). Coronary CTA-derived quantitative flow ratio (CT-QFR) is an on-site technique performed on acquired CTA images that estimates the functional severity of a coronary stenosis. However, CT-QFR measurements are available throughout the coronary vessel with no clear recommendations as to which specific values should be used for identifying obstructive CAD, e.g. most distal or lesion-specific values.
Purpose
First, to investigate the feasibility of CT-QFR and the correlation and agreement with invasive fractional flow reserve (FFR). Secondly, to compare the diagnostic performance of distal versus lesion-specific CT-QFR for identifying obstructive CAD defined by invasive coronary angiography (ICA) with FFR.
Methods
A total of 1732 prospectively included patients with symptoms suggestive of CAD referred for CTA were included. All patients with ≥50% diameter stenosis (DS) on CTA were subsequently referred for ICA with conditional FFR in lesions with 30–89%DS. Obstructive CAD was defined by ICA as FFR ≤0.80 or high-grade stenosis by visual assessment (≥90%DS). A blinded analysis of CT-QFR was performed in patients referred to ICA with measurements at the distal end of a vessel (distal CT-QFR) and 1 cm distal to stenotic lesions on CTA (lesion-specific). CT-QFR ≤0.80 was defined as abnormal. For correlation analyses to invasive FFR, CT-QFR was assessed corresponding to the position of the invasive pressure sensor.
Results
In total, 445/1732 (25%) patients had suspected obstructive CAD at CTA and underwent subsequent ICA. CT-QFR analysis was feasible in 423/445 (95%) patients. CT-QFR correlated (Pearson's rho 0.54, p<0.001) and agreed (mean difference –0.02±0.09) to FFR with CT-QFR overestimating FFR (Fig. 1). Obstructive CAD was identified in 190/423 (44%) patients by ICA. Distal and lesion-specific CT-QFR classified 196 (46%) and 171 (40%) patients as abnormal, respectively. Areas under the receiver-operating characteristic curves for distal versus lesion-specific CT-QFR were similar (0.86 (95% CI: 0.82–0.89) vs. 0.86 (0.82–0.90), p=0.80). Sensitivities for distal and lesion-specific CT-QFR were 78% (95% CI: 71–84) vs. 74% (67–80), p=0.01, respectively, and specificities 79% (95% CI: 74–84) vs. 87% (82–91), p<0.01, respectively. Distal and lesion-specific CT-QFR had similar diagnostic accuracy (79 (95% CI: 75–83), vs. 81 (77–85), p=0.07) (Fig. 2).
Conclusion
In patients with suspected obstructive CAD on CTA, non-invasive estimation of FFR using CT-QFR is feasible with moderate correlation and good agreement with invasive FFR. Overall diagnostic performance of distal and lesion-specific values for discriminating obstructive CAD by invasive FFR are similar. The use of CT-QFR could therefore potentially reduce the need for referral to invasive angiography after CTA.

Abstract
Abstract
Introduction
In patients with suspected obstructive coronary artery disease (CAD) on coronary computed tomography (CTA), guidelines endorse second-line selective testing for hemodynamic evaluation of suspected CAD. A variety of non-invasive modalities are available, and myocardial perfusion imaging with Rubidium-82 positron emission tomography (PET) is an established method with high diagnostic performance. Recently, an on-site method estimating computed tomography-derived quantitative flow ratio (CT-QFR) showed promising results for discriminating obstructive CAD. However, no study has compared the diagnostic performances of PET and CT-QFR.
Purpose
To assess a possible non-inferiority of CT-QFR compared to PET in patients with suspected obstructive CAD at CTA using invasive coronary angiography (ICA) with fractional flow reserve (FFR) as reference.
Methods
Patients (n=1732, 57% males, age 59±9.5) referred on a clinical indication with symptoms suggestive of obstructive CAD underwent routine CTA. Patients with ≥50% diameter stenosis (DS) on CTA were referred for PET and subsequent ICA with FFR. CT-QFR was analyzed post-hoc blinded to PET and ICA results.
Abnormal CT-QFR was defined as CT-QFR ≤0.80 in any vessel with a diameter ≥1.5mm. An independent core-lab evaluated PET scans as abnormal/normal with optional analyst-dependent application of pre-specified criteria; summed stress score of ≥4 in ≥2 contiguous segments, vessel-specific myocardial blood flow (MBF) <2.00 ml/g/min, global myocardial blood flow reserve ≤1.8, and/or transient ischemic dilatation ratio >1.13. Obstructive CAD was defined as ICA with FFR ≤0.80 or high-grade stenosis (≥90% DS).
Results
In total, 445/1732 patients (25%) had suspected obstructive CAD on CTA of whom 400/445 patients (90%) underwent subsequent PET and ICA. CT-QFR was successfully analysed in 383/400 (96%) patients classifying 174/383 (45%) patients as having disease. In comparison, PET classified 130/383 (34%) patients as having disease. In total, obstructive CAD by ICA with FFR was identified in 162 (42%) patients.
There was no significant difference in area under the receiver-operating characteristic curves for CT-QFR compared to the best performing PET metric (lowest vessel-specific MBF); 0.84 (95% CI 0.80–0.89) vs. 0.81 (0.77–0.85), p=0.19)) (Fig. 1). Overall diagnostic accuracy of CT-QFR versus PET was similar (78% (95% CI 74–82) vs. 77% (72–81), p=0.70. Sensitivities for CT-QFR and PET were 78% (71–84) and 63% (55–70), p<0.01, respectively, and specificities 78% (72–84) and 87% (82–91), p=0.01, respectively (Fig. 2). Three-vessel or left main disease on ICA was correctly identified in 30/31 patients by both CT-QFR and PET.
Conclusion
In patients with suspected obstructive CAD by CTA, second-line CT-QFR was non-inferior to PET for discriminating obstructive CAD by invasive FFR; Although diagnostic accuracy was similar, CT-QFR demonstrated higher sensitivity while PET showed higher specificity

Abstract
Abstract
Background
Coronary microvascular dysfunction (CMD) may be linked to small-vessel disease in other vascular beds as a part of multisystem disorder. However, there are limited data in support of this.
Purpose
We aim to determine whether reduced myocardial blood flow reserve (MBFR) is associated with an increased hazard of small-vessel disease in the kidneys and brain.
Method
We conducted a multicenter study of all patients consecutively referred for 82Rubidium-Positron emission tomography (82Rb-PET) myocardial perfusion CT imaging between January 2018 and August 2020. CMD was defined as MBFR ≤2. Patients were followed through national registries using ICD-10 codes with no loss to follow-up for microvascular events (ME) defined as chronic kidney disease, stroke, affective disorders, and dementia. Despite the heterogeneity of outcomes, they all play a crucial role in ME, with vascular dementia, affective disorders, and both ischemic and hemorrhagic strokes being major contributors to cerebral ME.
Results
Among the 7156 patients studied, 61.8% were men, median age was 69 [61–76 IQR] years, 14.1% had LVEF ≤40%, 58.4% had a previous diagnosis of ischemic heart disease (IHD) and 20.1% had atrial fibrillation. 38.9% had MBFR ≤2. MBFR was significantly associated with eGFR at baseline (r2=0.22, p<0.0001). After multivariable adjustment for demographics, cardiovascular risk factors, LVEF and reversible perfusion defects, MBFR remained significantly associated with eGFR, also in patients with no perfusion defects (β=0.039, 95% Cl 0.03–0.05, p<0.001 in all patients and β=0.039, 95% Cl 0.02–0.05, p<0.001, in patients with ≤5% reversible- and ≤5% irreversible hypoperfusion). During follow-up, a total of 677 (9.5%) ME were observed (480 (6.7%) cerebral ME and 197 (2.7%) renal ME). ME was more frequent in patients with MBFR ≤2 compared to MBFR >2 (11.2% vs. 5.5%, p<0.001).
In crude analysis MBFR ≤2 was significantly associated with ME (p<0.0001, Fig. 1) as well as renal- and cerebral ME (both p<0.001). Similar results were found in subgroup analysis of patients with diabetes, normal kidney function (eGFR ≥60) or no perfusion defects, respectively (Fig. 1). After multivariate adjusting for demographics, IHD, cardiovascular risk factors, Charlson's Comorbidity index, atrial fibrillation and stratifying by chronic kidney disease stages, MBFR remained a significant predictor of ME (HR 1.43, 95% CI 1.15–1.78, p<0.001, fig. 2). In subgroup analysis including only patients with no reversible perfusion defects, MBFR ≤2 was associated with a HR of 2.04, 95% CI 1.43–2.91, p<0.0001 for ME.
Conclusion
This is the first larger cohort study relating CMD to microvascular outcome in the kidneys and brain. We conclude that CMD is an independent predictor of cerebral and renal ME. Data support the hypothesis that CMD is part of a systemic vascular disorder.

Abstract
Introduction
Definitions used for suicide attempts and self-harm have been discussed for many years and is used differently in European countries, sometimes even interchangeably. Therefore, it is difficult to compare relevant rates across nations.
Objectives
This study aims at estimating the rate of suicide attempts and self-harm in chosen European countries in the more recent years when distinguishing between applied definitions.
Methods
A systematic search for relevant articles published between 2010-2020 will be performed in databases such as PubMed, Embase, PsycINFO, and Web of Science. Only articles in English or Danish will be included. Data will be collected for all age groups above 15 years of age. The prevalence of suicide attempts and self-harm will be calculated by a random effect model. Subgroup analyses will be performed to compare the rates according to age.
Results
from the performed systematic review and meta-study will be presented at the conference.
Conclusions
The conclusion will be presented when results have been analysed.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
Extragastric leiomyoblastomas are extremely rare. This is the sixth reported case of leiomyoblastoma of the greater omentum, and the only one with acute major bleeding which required an emergency operation. Leiomyoblastomas are low-grade malignant tumors, and especially the gastric ones have an excellent prognosis after surgical removal. Extragastric leiomyoblastomas have a higher rate of dissemination. However, none of the previously reported omental leiomyoblastomas showed signs of metastatic spread at the time of operation. The present patient is alive and well 18 months postoperatively.

Abstract
A formalism has been proposed for small and non-standard photon fields in which [Formula: see text] correction factors are used to correct dosimeter response in small fields (indiviual or composite) relative to that in a larger machine-specific reference (MSR) field. For clinical plans consisting of several fields, a plan-class specific reference (PCSR) plan can also be defined, serving as an intermediate calibration field between the MSR and clinical plans within a certain plan-class. In this work, the formalism was applied in the calculation of [Formula: see text] for 21 clinical plans delivered by the [Formula: see text] radiosurgery system, each plan employing one or two of the smallest diameter collimators: 5 mm, 7.5 mm, and 10 mm. Three detectors were considered: the Exradin A16 and A26 micro chambers, and the W1 plastic scintillator. The clinical plans were grouped into 7 plan-classes according to commonly shared characteristics. The suitability of using a PCSR plan to represent the detector response of each plan within the plan-class was investigated. Total and intermediate correction factors were calculated using the [Formula: see text] Monte Carlo user code. The corrections for the micro chambers were large, primarily due to the presence of the low-density air cavity and the volume averaging effect. The correction for the scintillator was found to be close to unity for most plans, indicating that this detector may be used to measure small clinical plan correction factors in any plan except for those using the 5 mm collimator. The PCSR plan was shown to be applicable to plan-classes comprising isocentric plans only, with plan-classes divided according to collimator size. For non-isocentric plans, the variation of [Formula: see text] as a function of the point of measurement within a single plan, as well as the high inter-plan-class variability of the correction factor, precludes the use of a PCSR plan.

Abstract
Monogenean parasite infestations are common in captive marine teleosts, and are generally found on the skin and gills. This report describes an unusual pathological presentation of exuberant granulation tissue of the gills, suspected to be related to Neobenedenia infestation in two cobia housed together at a North Carolina aquarium.

Abstract
AIMS To investigate the effect of glucagon-like peptide 1 receptor agonist liraglutide on the counter-regulatory hormone response to hypoglycaemia in type 1 diabetes. METHODS We conducted a randomized, double-blind, placebo-controlled, single-centre trial, in which a total of 45 adults with type 1 diabetes [mean ± standard deviation age 34.5 ± 11.2 years, BMI 23.9 ± 2.4 kg/m(2) , glycated haemoglobin (HbA1c) 7.6 ± 0.8%, diabetes duration 16.6 ± 9.4 years] underwent a hypoglycaemic clamp after 4 weeks' crossover treatment with once-daily liraglutide/placebo added to insulin in one of three liraglutide dose groups: 0.6 mg (n = 15); 1.2 mg (n = 14); and 1.8 mg (n = 16). The main outcome measure was glucagon concentration at nadir plasma glucose (2.5 mmol/l). Clinical outcomes were also evaluated. Five participants were withdrawn from the trial; three because of adverse events. All participants were included in the analysis. RESULTS Glucagon concentration at nadir plasma glucose was modest, trending towards lower concentrations at increasing liraglutide dose versus placebo: 34.7 versus 38.1 pg/ml, p = 0.555 (0.6 mg); 28.8 versus 37.2 pg/ml, p = 0.126 (1.2 mg); and 28.4 versus 37.5 pg/ml, p = 0.092 (1.8 mg). There was no difference, however, between liraglutide and placebo in incremental change in glucagon during hypoglycaemia. Other counter-regulatory hormone levels increased during hypoglycaemia with no systematic differences between groups. Glucose infusion rates were significantly lower with liraglutide versus placebo during the clamp. After 4 weeks' treatment, HbA1c remained unchanged in the liraglutide and placebo groups. Greater reductions in insulin dose and body weight were seen with liraglutide versus placebo. CONCLUSIONS Liraglutide did not compromise hypoglycaemic responses in type 1 diabetes after 4 weeks' treatment.

Abstract
Activation of the G protein-coupled free fatty acid receptor 1 (FFA1; formerly known as GPR40) leads to an enhancement of glucose-stimulated insulin secretion from pancreatic β-cells. TUG-469 has previously been reported as a potent FFA1 agonist. This study was performed to confirm the higher in vitro potency of TUG-469 compared to the reference FFA1 agonist GW9508 and to prove in vivo activity in a pre-diabetic mouse model. The in vitro pharmacology of TUG-469 was studied using Ca(2+)-, cAMP-, and impedance-based assays at recombinant FFA1 and free fatty acid receptor 4, formerly known as GPR120 (FFA4) expressing 1321N1 cells and the rat insulinoma cell line INS-1. Furthermore, we investigated the systemic effect of TUG-469 on glucose tolerance in pre-diabetic New Zealand obese (NZO) mice performing a glucose tolerance test after intraperitoneal administration of 5 mg/kg TUG-469. In comparison to GW9508, TUG-469 showed a 1.7- to 3.0-times higher potency in vitro at 1321N1 cells recombinantly expressing FFA1. Both compounds increased insulin secretion from rat insulinoma INS-1 cells. TUG-469 is > 200-fold selective for FFA1 over FFA4. Finally, a single dose of 5 mg/kg TUG-469 significantly improved glucose tolerance in pre-diabetic NZO mice. TUG-469 turned out as a promising candidate for further drug development of FFA1 agonists for treatment of type 2 diabetes mellitus.

Abstract
BACKGROUND There is a lack of specific knowledge about the dose-response effect of multiple parental risk factors for suicide attempts among children and adolescents. The aim of this study was to determine the dose-response effect of multiple parental risk factors on an offspring's risk for suicide attempt. METHOD We designed a population-based two-generation nested case-control study and used Danish register data. A population of 403 431 individuals born between 1983 and 1989 was sampled. Among these, 3465 (0.8%) were registered as having had a suicide attempt. Twenty controls were matched to each case and a link to the offspring's biological parents was established. RESULTS There was a dose-response relationship between the number of exposures and the risk of suicide attempts, with the increased risk seeming to be a multiplicative effect. Parental suicide, suicide attempt, psychiatric illness and low level of income were all significant independent risk factors for offspring's suicide attempts. CONCLUSIONS Knowledge of the effect of multiple risk factors on the likelihood of suicide attempts in children and adolescents is important for risk assessment. Dose-response effects of multiple parental risk factors are multiplicative, but it is rare for children and adolescents to be exposed to multiple parental risk factors simultaneously. Nevertheless, they should be considered along with the offspring's own multiple risk factors in determining the overall risk of a suicide attempt. Further research incorporating both parental and offspring's risk factors is indicated to determine the overall dose-response effect of multiple risk factors.

Abstract
BACKGROUND A range of studies have found an association between some somatic diseases and increased risk of suicide and attempted suicide. These studies are mostly analyses of adult populations and illnesses related to adulthood. OBJECTIVES To study the risk of attempted suicide in children and youths with a somatic diagnosis, and to assess a possible association from a somatic perspective. METHODS From a cohort of 403 431 individuals (born 1983-89), 3465 children and youths who had attempted suicide were identified. Each case was matched with 20 population controls. 72 765 children and youths constituted the case-control population. All data were obtained from national population registers and analysed in a nested case-control design. RESULTS Contact of children and youths with a somatic hospital is correlated with increased risk of attempted suicide; the risk peaks in the time immediately after contact. Risk factors were treatment for injury caused by violence, epilepsy, asthma and malformation for males; and spontaneous and medical abortions, treatment for injury caused by violence, epilepsy, asthma, insulin dependent diabetes mellitus and malformation for females. Not all the mentioned diagnoses were significant in the adjusted model. CONCLUSIONS Based on the results of the study a strategy to minimise the risk of attempted suicide among children and youths must be implemented. The strategy should mainly focus on children at high risk-that is, children from families with low socioeconomic status, and children with a psychiatric history, a history of previous suicide attempts and with an unstable somatic disease subsequently causing many admissions.

Abstract
BACKGROUND Fluid management during orthotopic liver transplantation poses unique challenges for the anesthesiologist. Maintenance of hypovolemia as indicated by low central venous pressure has been associated with reduced blood loss and improved outcomes in some studies, but with higher 30-day mortality and increased incidence of renal dysfunction in others. The primary aim was to evaluate the association of central venous pressure management after liver allograft reperfusion with immediate postoperative patient outcomes. METHODS This was a retrospective investigation evaluating the intraoperative and postoperative records of 144 consecutive patients who underwent orthotopic liver transplantation at a single institution. RESULTS We did not find any important association between central venous pressure management after graft reperfusion and postoperative patient outcomes. Specifically, these data do not support the hypothesis that maintenance of lower central venous pressure during the post-anhepatic phase of orthotopic liver transplantation is associated with improved immediate postoperative allograft function (except for a steeper decrease in post operative days 1-3 in 2 of the 3 liver function test: alanine aminotransferase and bilirubin) or overall patient survival, graft survival, composite graft/patient survival, intensive care length of stay, hospital length of stay or the occurrence of infections. CONCLUSION Maintaining a lower central venous pressure during the post-anhepatic phase during orthotopic liver transplantation is not associated with any benefit in terms of immediate postoperative allograft function, graft survival or patient survival.

Abstract
The Kveim reaction was studied in vivo in 50 patients with sarcoidosis. Commonwealth Serum Laboratories Kveim material and a new Danish Kveim material gave 14 and 8 positive reactions respectively, as well as 6 and 8 equivocal reactions. Forty-six of the patients were also tested in vitro for cell mediated immunity to the Danish Kveim material, using both the leucocyte migration agarose technique and the capillary technique. No significant migration inhibition or stimulation were found. A tuberculin skin test was performed in 49 of the patients, and in 45 a dinitrochlorobenzene sensitivity titer was determined. Both tests revealed a depression of the cell mediated immunity. The serum levels of immunoglobulins IgG, IgA, IgM, IgD, and IgE were determined. The serum of each patient was also examined to determine if organ-non-specific and granulocyte-specific antinuclear factors of IgG class, antibodies against native DNA, rheumatoid factor, mitochondrial antibodies, antibodies against thyroid cytoplasm, and parietal cell antibodies were present. IgG levels were above normal in 28 patients; IgE was above normal in 10 patients, 4 of whom were atopics or had an atopic disposition. Organ-non-specific antinuclear factors were present in 17 patients.

Abstract
Antibodies against double-stranded (ds) DNA were demonstrated by an immunofluorescence technique using Crithidia luciliae kinetoplast as antigen, and by means of the Farr technique. Both techniques were used simultaneously in 172 sera from patients with systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), juvenile rheumatoid arthritis (JRA), temporal arteritis (TA) and from healthy controls. Comparable results were obtained with the two techniques. SLE patients with active disease had higher titres of IgA antibodies than patients with inactive disease. Of the patients with RA and JRA, 10% had significant titres of dsDNA antibodies. Patients with TA and normal controls had either no dsDNA antibodies in their sera or very low titres without complement-fixing properties.

Abstract
Mucinous cystadenomas of the appendix are rare, with significant malignant potential [Lo and Sarr in Hepatogastroenterology 50(50):432-437, 2003]. Carcinoid tumours are similarly uncommon, rarely occurring in Meckel's diverticula but are still the commonest tumour of Meckel's diverticulae [Nies et al. in Dis Colon Rectum 35(6):589-596, 1992; Modlin and Lye in Cancer 97(4):934-959, 2003; Sutter et al. in Schweiz Med Wochenschr Suppl 89:20S-24S, 1997; Weber and McFadden DW in J Clin Gastroenterol 11(6):682-686, 1989]. A 77-year-old woman presented to our clinic with a 6-week history of non-specific lower abdominal pain. A pelvic ultrasound showed an 8 × 3 × 2.5 cm mass in the right iliac fossa. Colonoscopy and CT confirmed this mass and also revealed a left colonic tumor. At laparotomy, three tumours were identified; in the appendix, a Meckel's diverticulum, and the descending colon. A subtotal colectomy and diverticulectomy were performed. Histology confirmed a T3N0 Dukes B colonic adenocarcinoma, a carcinoid of Meckel's diverticulum and a mucinous adenoma of the appendix. The patient is tumor free to date, 5 years after presentation. The presence of three synchronous tumours of different histological origin in the gastrointestinal tract has not previously been described in the literature.

Abstract
BACKGROUND Epidemiological studies of mental health problems in the first years of life are few. This study aims to investigate infancy predictors of psychopathology in the second year of life. METHODS A random general population sample of 210 children from the Copenhagen Child Birth Cohort CCC 2000 was investigated by data from National Danish registers and data collected prospectively from birth in a general child health surveillance programme. Mental health outcome at 1(1/2) years was assessed by clinical and standardised measures including the Child Behavior Check List 1(1/2)-5 (CBCL 1(1/2)-5), Infant Toddler Symptom Check List (ITSCL), Checklist for Autism in Toddlers (CHAT), Bayley Scales of Infant Development (BSID II), Mannheim Eltern Interview (MEI), Parent Child Early Relational Assessment (PC ERA) and Parent Infant Relationship Global Assessment Scale (PIR-GAS), and disordered children were diagnosed according to the International Classification of Diseases (ICD-10) and Diagnostic Classification Zero to Three (DC: 0-3). RESULTS Deviant language development in the first 10 months of life predicted the child having any disorder at 1(1/2) years, OR 3.3 (1.4-8.0). Neuro-developmental disorders were predicted by deviant neuro-cognitive functioning, OR 6.8 (2.2-21.4), deviant language development, OR 5.9 (1.9-18.7) and impaired social interaction and communication, OR 3.8 (1.3-11.4). Unwanted pregnancy and parents' negative expectations of the child recorded in the first months of the child's life were significant predictors of relationship disturbances at 1(1/2) years. CONCLUSIONS Predictors of neuro-developmental disorders and parent-child relationship disturbances can be identified in the first 10 months of life in children from the general population.

Abstract
The etiology of exercise-induced rib stress fractures (RSFs) in elite rowers is unclear. The purpose of the study was to investigate thoracic muscle activity, movement patterns and muscle strength in elite rowers. Electromyographic (EMG) and 2-D video analysis were performed during ergometer rowing, and isokinetic muscle strength was measured in seven national team rowers with a history of RSF and seven matched controls (C). RSF displayed a higher velocity of the seat in the initial drive phase (RSF: 0.25+/-0.03, 0.25 (0.15-0.33) m/s vs C: 0.15+/-0.06, 0.18 (-0.11-0.29) m/s P=0.028) (Mean+/-SEM, median and range). Further, RSF had greater co-contraction of m. serratus anterior and m. trapezius in the mid-drive phase (RSF: 47.5+/-3.4, 48.5 (35.8-60.2)% EMG signal overlap vs C: 30.8+/-6.5, 27.0 (11.2-61.6)%P=0.043). In addition, the RSF subjects showed a lower knee-extension to elbow-flexion strength ratio (RSF: 4.2+/-0.22, 4.3 (3.5-5.1) vs C: 4.8+/-0.16, 5.0 (4.2-5.3) P=0.043), indicating stronger arms relative to legs compared with controls. In conclusion, increased thoracic muscle co-contraction, altered movement patterns and reduced leg/arm strength ratio were observed in the RSF subjects, which may all predispose toward an increased risk of RSF.

Abstract
The research of psychopathology in children 0-3 years of age is dominated by clinical case studies and theoretical reflections, and epidemiological studies are few. This paper reviews methods to assess and classify psychopathology in children 0-3 years old in an epidemiological context. Diagnostic assessments of children 0-3 years of age are based on information from different sources and investigation of several domains of mental functioning, and the rapid developmental changes and the relationship context are taken into account. The reviewed literature shows a range of methods to assess and classify psychopathology in children 0-3 years of age: screening instruments with established psychometric properties, such as the Child Behaviour Checklist (CBCL) and the Checklist for Autism in Toddlers (CHAT), and methods of in-depth assessment known from both clinical practice and research: developmental tests, such as the Bayley Scales, and relationship assessments, such as the Early Relational Assessment (ERA). The classification of psychopathology in young children can be approved by the Diagnostic Classification 0-3. The reliability and validity of DC 0-3 have not yet been established, but preliminary results seem promising. The demands made on diagnostic assessment procedures in epidemiological research of children 0-3 years of age can be met by a combination of well-established research instruments, such as the CBCL, with in-depth clinical assessment procedures, such as the Bayley Scales and the ERA, and diagnostic classification by DC 0-3.

Abstract
BACKGROUND Experimental difficulties have so far restricted knowledge of the effects of energy imbalance on change in body weight. Direct measurement requires that the subjects are kept under dietary supervision for several months while the activity is being measured. MATERIALS AND METHODS The effects of energy balance can be calculated using a combination of fundamental principles and directly measurable data: the law of energy conservation (increase in combustible energy equals the difference between energy intake and energy expenditure); data on energy expenditure of fat and lean tissues; and data on the composition of added/removed tissue during weight change. RESULTS AND CONCLUSIONS We obtained an explicit differential equation describing the development of body weight over time, with energy intake and energy expenditure as control variables. Using this model it is possible to isolate and analyse the measured effects of parameters not included in the model, such as age or 'adaptivity' of the body.

Abstract
Blunted insulin-stimulated endothelial function may be a mechanism for the development of atherothrombotic disease in type 2 diabetes, but it is unknown whether hypoglycemic drug therapy can modulate this abnormality. We studied patients with type 2 diabetes and stable ischemic heart disease (n = 28) and lean, healthy control subjects (n = 31). Forearm blood flow was measured by venous occlusion plethysmography during dose-response studies of acetylcholine (ACh) and sodium nitroprusside (SNP) infused into the brachial artery. In the patients and 10 healthy control subjects, ACh was repeated after intrabrachial infusion of insulin. Patients were restudied after 2 months of insulin therapy with four daily subcutaneous injections (treatment group, n = 19) or without hypoglycemic drug therapy (time control group, n = 9). Insulin infusion raised venous serum insulin in the forearm to high physiological levels (133 +/- 14.6 mU/l in patients) with a minor increase in systemic venous serum insulin. This increased the ACh response by 149 +/- 47, 110 +/- 33, 100 +/- 45, and 106 +/- 44% during the four ACh doses in healthy control subjects (P < 0.0001) but had no effect in patients (P = 0.3). After 2 months, HbA(1c) in the treatment group had decreased from 10.0 +/- 0.4 to 7.5 +/- 0.2%. Although neither the ACh response (P = 0.09) nor the SNP response (P = 0.4) had changed significantly, insulin stimulation had a significant effect, as the ACh response increased by 58 +/- 25, 84 +/- 66, 120 +/- 93, and 69 +/- 36% (P = 0.0002). In the time control group, insulin stimulation remained without effect after 8 weeks (P = 0.7). In conclusion, insulin therapy partly restores insulin-stimulated endothelial function in patients with type 2 diabetes and ischemic heart disease.

The photoaffinity phosphate analogue 4-azido-2 nitrophenyl phosphate (ANPP) was shown previously (Pougeois, R., Lauquin, G. J.-M., and Vignais, P. V. (1983) Biochemistry 22, 1241-1245) to bind covalently and specifically to a single catalytic site on one of the three beta-subunits of the isolated chloroplast coupling factor 1 (CF(1)). Modification by ANPP strongly inhibited ATP hydrolysis activity. In this study, we examined labeling of membrane-bound CF(1) by ANPP by exposing thylakoid membranes to increasing concentrations of the reagent. ANPP exhibited saturable binding to two sites on CF(1), one on the beta-subunit and one on the alpha-subunit. Labeling by ANPP resulted in the complete inhibition of both ATP synthesis and ATP hydrolysis by the membrane-bound enzyme. Labeling of both sites by ANPP was reduced by more than 80% in the presence of P(i) (> or = 10 mM) and ATP (> or = 0.5 mM). ADP was less effective in competing with ANPP for binding, giving a maximum of approximately 35% inhibition at concentrations > or = 2 mM. ANPP-labeled tryptic peptides of the alpha-subunit were isolated and sequenced. The majority of the probe was contained in three peptides corresponding to residues Gln(173) to Arg(216), Gly(217) to Arg(253), and His(256) to Arg(272) of the alpha-subunit. In the mitochondrial F(1) (Abrahams, J. P., Leslie, A. G. W., Lutter, R., and Walker, J. E. (1994) Nature 370, 621-628), all three analogous peptides are located within the nucleotide binding pocket and within close proximity to the gamma-phosphate binding site. The data indicate, however, that the azidophenyl group of bound ANPP is oriented at approximately 180 degrees in the opposite direction to the adenine binding site with reference to the phosphate binding site on the alpha-subunit. The study has confirmed that ANPP is a bona fide phosphate analogue and suggests that it specifically targets the gamma-phosphate binding site within the nucleotide binding pockets on the alpha- and beta-subunits of CF(1). The study also indicates that in the resting state of the chloroplast F(1)-F(0) complex both the alpha- and beta-subunits are structurally asymmetric.

Abstract
The long-term efficacy and safety of oral Viagra (sildenafil citrate), a selective phosphodiesterase 5 inhibitor, and the effect of withdrawing treatment were evaluated in men with erectile dysfunction (ED). In 233 men with ED of psychogenic or mixed organic/psychogenic aetiology, 16 weeks of open-label, flexible-dose sildenafil treatment (10-100 mg) was followed by eight weeks of double-blind, fixed-dose, randomised withdrawal to placebo or continued treatment with sildenafil. Sildenafil was taken as needed (not more than once daily) approximately 1 h prior to sexual activity. The main outcome measures were a global efficacy question, a sexual function questionnaire, an event log of erections, and adverse event recording. In the open-label phase, 200 of 216 patients (93%) reported improved erections with sildenafil; 28 patients (12%) discontinued treatment. In the double-blind phase, the significant improvements in the frequency and duration of erections were maintained in the sildenafil group but returned to pre-treatment values in patients on placebo (P values < 0.0001 versus placebo). The most frequent adverse events in the sildenafil group during the double-blind phase were flushing (7%), headache (6%), and dyspepsia (5%). Of the 192 patients enrolled in the 1-y extension, 90% completed the study; only two patients (1%) were withdrawn due to lack of efficacy. In men with ED of psychogenic or mixed aetiology, oral sildenafil is effective and well-tolerated both at the initiation of therapy and during long-term treatment. For most patients, sildenafil treatment must be continued for improvements in erectile function to be maintained.

Abstract
OBJECTIVE The most accurate way to measure urinary iodine excretion in epidemiological surveys is still debated. We propose a new principle of estimating iodine excretion based on casual urine samples. MATERIAL AND METHODS A total of 123 24 h urine samples and corresponding casual urine samples were collected from 31 subjects. Iodine excretion was expressed as 24 h iodine excretion and three different estimates: iodine concentration in the casual sample, iodine/gram creatinine in the casual sample, and the new principle-iodine/creatinine ratio in the casual sample, adjusted for expected creatinine excretion of the individual. RESULTS All three estimates based on casual urine samples correlated significantly to 24 h values with a r (Pearson) of 0.37 for iodine concentration, 0. 61 for iodine/creatinine ratio and 0.62 for the age- and sex-adjusted iodine/creatinine ratio. The median iodine excretion in the entire group was 143 microg/day in 24 h samples, 87 microg/l as iodine concentration, 77 microg/g creatinine as iodine/creatinine ratio and 126 microg/day as age- and sex-adjusted iodine/creatinine ratio. CONCLUSION Age- and sex-adjusted iodine/creatinine ratio is a more accurate and unbiased estimate of iodine excretion in epidemiological surveys of adults than the two most frequently used estimated: iodine concentration and iodine/gram creatinine, as these two estimates may introduce a bias depending on the composition of the investigated group. The adjusted iodine/creatinine ratio is superior to the other estimates, especially when individual estimates of 24 h iodine excretion is required or cohorts of selected groups are investigated.
