Abstract
Abstract
Introduction
The congenital Long QT Syndrome (cLQTS) is associated with an increased risk of sudden cardiac death (SCD). Thus, cLQTS patients are susceptible to develop depression or anxiety, both of which have been associated with poor outcomes including risk of mortality.
Aim
We examined if a cLQTS diagnosis and the severity of cLQTS disease onset was associated with an increased risk of depression, anxiety, and all-cause mortality compared with a matched control population.
Methods
Using Danish nationwide registries and inherited cardiac disease clinics, we identified all patients with known cLQTS (1994–2016) who were ≥18 years at the time of diagnosis. The disease onset for cLQTS was identified as asymptomatic, ventricular tachycardia [VT]/ syncope, aborted SCD [aSCD], or unknown (i.e. no available information). After cLQTS diagnosis, we determined the risk of depression (i.e. depression diagnosis or prescription of antidepressants), anxiety (i.e. anxiety diagnosis or prescription of anxiolytics), and mortality using multivariable Cox proportional hazards regression. Patients were followed for three years. An age and gender matched control population was identified (matching 1:4). Competing risk analysis with death as competing risk was used to generate cumulative incidence plots.
Results
Overall, 428 cLQTS patients were identified of which 107/428 (25%) developed depression or anxiety after being diagnosed with cLQTS compared with 285/1712 (16.6%) from the control population (p<0.001). The severity of disease onset was identified for 229/428 (55%) cLQTS patients; 104 (24%) were asymptomatic, 89 (21%) had VT/ syncope, and 36 (8.4%) had aSCD. A graded relationship between the severity of cLQTS disease onset and risk of depression or anxiety was identified (Figure 1). In multivariable models, patients with aSCD as disease onset had a higher risk of developing depression or anxiety compared with asymptomatic cLQTS patients (HR=2.34, CI: 1.03–5.32). Furthermore, previous depression (HR=6.38, CI: 4.80–8.48) and anxiety (HR=4.20, CI: 3.15–5.59) was found as associated risk factors. However, no risk was associated with concurrent treatment with beta-blockers (HR=1.23, CI: 0.90–1.69). During follow-up, 8 cLQTS patients died of which 4 had developed depression or anxiety (50%). No significant association between all-cause mortality and depression or anxiety was found, although numbers were low (P=0.22).
Conclusion
The prevalence of depression and anxiety was high among cLQTS patients after diagnosis. Moreover, a graded relationship between severity of disease onset and risk of depression or anxiety was identified. These findings highlight a need for increased awareness following a cLQTS diagnosis in order to reduce the risk of adverse outcomes.

Abstract
Abstract
Background
Syncope is a common condition in the general population causing frequent hospitalisation and visits to the emergency department. Family aggregation and twin studies have previously indicated that syncope and collapse has a heritable component.
Purpose
We investigated whether common genetic variants predispose to syncope and collapse.
Methods
We used genome-wide association data on syncope and collapse for 408,961 individuals with European ancestry from the UK Biobank study. In a replication study, the Integrative Psychiatric Research Consortium (iPSYCH) cohort (n=86,189) was used to investigate the risk of incident syncope stratified by genotype carrier status.
Results
We report on a genome-wide significant locus on chromosome 2q32.1 with the lead SNP rs12465214 (odds ratio [OR] = 1.13, 95% confidence interval [CI] = 1.10–1.17, P=5.8x10–15; Figure 1a). This association was replicated in the iPSYCH cohort, where homozygous carriers of the C allele conferred an increased hazard ratio (HR=1.30, CI: 1.15–1.46, P=1.68x10–5; Figure 1b). LD score regression demonstrated a significant genetic correlation (rg) with coronary artery disease (rg=0.41, P=6.99x10–15) and related phenotypes such as angina and hypertension (Figure 1c). Analyses of eQTL (P=4x10–8) and epigenetic chromatin states revealed that variation in this locus likely affects expression of the gene ZNF804A, which resides in its proximity (Figure 1d). A qPCR analysis showed that ZNF804A was mostly expressed in the brain. A lower level of ZNF804A expression was also detected in the cerebral arteries. ZNF804A was not expressed in heart tissue.
Figure 1
Conclusion
rs12465214 is associated with syncope and collapse. Variation in this locus likely modulates the expression of the nearby gene ZNF804A through eQTLs and chromatin interactions. ZNF804A is mainly expressed in the brain and cerebral arteries. However, the precise function of ZNF804A is unknown. Furthermore, syncope and collapse is a polygenetic trait and share a significant genetic overlap with coronary artery disease, angina and hypertension.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Influenza virus infection causes worldwide seasonal epidemics. Although influenza is usually a mild disease, a minority of patients experience very severe fulminating disease courses. Previous studies have demonstrated a role for type I interferon (IFN) in anti-viral responses during influenza. So far, however, IFN regulatory factor (IRF)7 deficiency is the only genetic cause of severe influenza described in humans. In this study we present a patient with severe influenza A virus (IAV) H1N1 infection during the 2009 swine flu pandemic. By whole exome sequencing we identified two variants, p.R71H and p.P885S, located in the caspase activation and recruitment domain (CARD) and RNA binding domains, respectively, of DExD/H-box helicase 58 (DDX58) encoding the RNA sensor retinoic acid inducible gene 1 (RIG-I). These variants significantly impair the signalling activity of RIG-I. Similarly, patient cells demonstrate decreased antiviral responses to RIG-I ligands as well as increased proinflammatory responses to IAV, suggesting dysregulation of the innate immune response with increased immunopathology. We suggest that these RIG-I variants may have contributed to severe influenza in this patient and advocate that RIG-I variants should be sought in future studies of genetic factors influencing single-stranded RNA virus infections.

Abstract
OBJECTIVES Discrimination between HIV-1 and HIV-2 is important to ensure appropriate antiretroviral treatment (ART) and epidemiological surveillance. However, serological tests have shown frequent mistyping when applied in the field. We evaluated two confirmatory tests, INNO-LIA HIV I/II Score and ImmunoComb HIV 1/2 BiSpot, for HIV type discriminatory capacity. METHODS Samples from 239 ART-naïve HIV-infected patients from the Bissau HIV Cohort in Guinea-Bissau were selected retrospectively based on the initial HIV typing performed in Bissau, ensuring a broad representation of HIV types. INNO-LIA results were interpreted by the newest software algorithm, and three independent observers read the ImmunoComb results. HIV-1/HIV-2 RNA and DNA were measured for confirmation. RESULTS INNO-LIA results showed 123 HIV-1 positive samples, 69 HIV-2 positive and 47 HIV-1/2 dually reactive. There was agreement between INNO-LIA and HIV-1/HIV-2 RNA and DNA detection, although not all HIV-1/2 dually reactive samples could be confirmed by the nucleic acid results. Overall, the observers found that the ImmunoComb results differed from the INNO-LIA results, with agreements of 90.4, 91.2 and 92.5%, respectively, for HIV-1, HIV-2 and HIV-1/2. The combined kappa-score for agreement between the three observers was 0.955 (z-score 35.1; P < 0.01). Of the HIV-2 mono-reactive samples (INNO-LIA), the three observers interpreted 24.6-31.9% as HIV-1/2 dually infected by ImmunoComb. None of these samples had detectable HIV-1 RNA or DNA. CONCLUSIONS There was accordance between INNO-LIA calls and nucleic acid results, whereas ImmunoComb overestimated the number of HIV-1/2 dually infected patients. Confirmatory typing is needed for patients diagnosed with HIV-1/2 dual infection by ImmunoComb.

Abstract
This study ascertains the ability of bodyweight blood flow-restricted (BFR) exercise training to promote skeletal muscle adaptations of significance for muscle accretion and metabolism. Six healthy young individuals (three males and three females) performed six weeks of bodyweight BFR training. Each session consisted of five sets of sit-to-stand BFR exercise to volitional failure with 30-second inter-set recovery. Prior to, and at least 72 h after training, muscle biopsies were taken from m. vastus lateralis to assess changes in fibre type-specific cross-sectional area (CSA), satellite cell (SC) and myonuclei content and capillarization, as well as mitochondrial protein expression. Furthermore, magnetic resonance imaging was used to assess changes in whole thigh muscle CSA. Finally, isometric knee extensor muscle strength was evaluated. An increase in knee extensor whole muscle CSA was observed at middle and distal localizations after training (3·2% and 3·5%, respectively) (P<0·05), and a trend was observed towards an increase in type I fibre CSA, whereas muscle strength did not increase. Additionally, the number of SCs and myonuclei associated with type I fibres increased by 65·7% and 20%, respectively (P<0·05). No significant changes were observed in measures of muscle capillarization and mitochondrial proteins. In conclusion, six weeks of bodyweight-based BFR exercise promoted myocellular adaptations related to muscle accretion, but not metabolic properties. Moreover, the study revealed that an appropriate total training volume needs further investigation before recommending bodyweight BFR to patient populations.

Abstract
During evolution, mitochondrial DNA haplogroups of arctic populations may have been selected for lower coupling of mitochondrial respiration to ATP production in favor of higher heat production. We show that mitochondrial coupling in skeletal muscle of traditional and westernized Inuit habituating northern Greenland is identical to Danes of western Europe haplogroups. Biochemical coupling efficiency was preserved across variations in diet, muscle fiber type, and uncoupling protein-3 content. Mitochondrial phenotype displayed plasticity in relation to lifestyle and environment. Untrained Inuit and Danes had identical capacities to oxidize fat substrate in arm muscle, which increased in Danes during the 42 days of acclimation to exercise, approaching the higher level of the Inuit hunters. A common pattern emerges of mitochondrial acclimatization and evolutionary adaptation in humans at high latitude and high altitude where economy of locomotion may be optimized by preservation of biochemical coupling efficiency at modest mitochondrial density, when submaximum performance is uncoupled from VO2max and maximum capacities of oxidative phosphorylation.

Abstract
AIM MicroRNAs (miRNAs) have regulatory functions in organs critical in resuscitation from sudden cardiac arrest due to ventricular fibrillation (VF-SCA); therefore, circulating miRNAs may be markers of VF-SCA outcome. METHODS We measured candidate miRNAs (N=45) in plasma using qRT-PCR among participants of a population-based VF-SCA study. Participants were randomly selected cases who died in the field (DF, n=15), died in hospital (DH, n=15), or survived to discharge (DC, n=15), and, age-, sex-, and race-matched controls (n=15). MiRNA levels were compared using ANOVA, t-tests, and fold-changes. RESULTS Mean age of groups ranged from 66.9 to 69.7. Most participants were male (53-67%) and white (67%). Comparing cases to controls, plasma levels of 17 miRNAs expressed in heart, brain, liver, and other tissues (including miR-29c, -34a, -122, -145, -200a, -210, -499-5p, and -663b) were higher and three non-specific miRNAs lower (miR-221, -330-3p, and -9-5p). Among DH or DC compared with DF cases, levels of two miRNAs (liver-specific miR-122 and non-specific miR-205) were higher and two heart-specific miRNAs (miR-208b and -499-5p) lower. Among DC vs. DF cases, levels of three miRNAs (miR-122, and non-specific miR-200a and -205) were higher and four heart-specific miRNAs (miR-133a, -133b, -208b, and -499-5p) lower. Among DC vs. DH cases, levels of two non-specific miRNAs (miR-135a and -9-3p) were lower. CONCLUSIONS Circulating miRNAs expressed in heart, brain, and other tissues differ between VF-SCA cases and controls and are related to resuscitation outcomes. Measurement of miRNAs may clarify mechanisms underlying resuscitation, improve prognostication, and guide development of therapies. Results require replication.

Abstract
Herpes simplex encephalitis (HSE) in children has previously been linked to defects in type I interferon production downstream of Toll-like receptor (TLR)3. In the present study, we used whole-exome sequencing to investigate the genetic profile of 16 adult patients with a history of HSE. We identified novel mutations in IRF3, TYK2 and MAVS, molecules involved in generating innate antiviral immune responses, which have not previously been associated with HSE. Moreover, data revealed mutations in TLR3, TRIF, TBK1 and STAT1 known to be associated with HSE in children but not previously described in adults. All discovered mutations were heterozygous missense mutations, the majority of which were associated with significantly decreased antiviral responses to HSV-1 infection and/or the TLR3 agonist poly(I:C) in patient peripheral blood mononuclear cells compared with controls. Altogether, this study demonstrates novel mutations in the TLR3 signaling pathway in molecules previously identified in children, suggesting that impaired innate immunity to HSV-1 may also increase susceptibility to HSE in adults. Importantly, the identification of mutations in innate signaling molecules not directly involved in TLR3 signaling suggests the existence of innate immunodeficiencies predisposing to HSE beyond the TLR3 pathway.

Abstract
OBJECTIVES Lipid-based nutrient supplements (LNSs) are increasingly used in HIV programmes in resource-limited settings. However, the possible effects of LNSs on the plasma concentrations of antiretroviral drugs have not been assessed. Here, we aimed to assess the effects of LNSs on plasma efavirenz and nevirapine trough concentrations in Ethiopian adult HIV-infected patients. METHODS The effects of LNSs were studied in adults initiating antiretroviral therapy (ART) in a randomized trial. Patients with body mass index (BMI) > 17 kg/m(2) (n = 282) received daily supplementation of an LNS containing whey (LNS/w), an LNS containing soy (LNS/s) or no LNS. Trough plasma concentrations of efavirenz and nevirapine were measured at 1 and 2 months. Genotyping for 516 G>T and 983 T>C polymorphisms of the cytochrome P450 (CYP) 2B6 locus was performed. Multilevel linear mixed-effects models were used to assess the associations between LNS and plasma efavirenz and nevirapine concentrations. RESULTS In patients with BMI > 17 kg/m(2), nevirapine concentrations were lower in the LNS/w and LNS/s groups by a median of -2.3 μg/mL [interquartile range (IQR) -3.9; -0.9 μg/mL; P = 0.002] and -2.1 μg/mL (IQR -3.9; -0.9 μg/mL; P = 0.01), respectively, compared with the group not receiving supplements. There were no differences between groups with respect to efavirenz plasma concentrations. The CYP2B6 516 G>T polymorphism was associated with a 5 μg/mL higher plasma efavirenz concentration compared with the wild type (P < 0.0001), while it was not associated with plasma nevirapine concentrations. CONCLUSIONS Intake of an LNS was associated with lower plasma nevirapine trough concentrations, indicating possible drug-LNS interactions. The clinical relevance of such reductions in nevirapine exposure is not clear. Plasma efavirenz concentration was not affected by the LNS.

Abstract
Recent efforts to develop reliable and efficient early pregnancy screening programmes for pre-eclampsia have focused on combining clinical, biochemical and biophysical markers. The same model has been used for first-trimester screening for fetal aneuploidies i.e. prenatal diagnosis (PD), which is routinely offered to all pregnant women in many developed countries. Some studies suggest combining PD and pre-eclampsia screening, so women can be offered testing for a number of conditions at the same clinical visit. A combination of these tests may be practical in terms of saving time and resources; however, the combination raises ethical issues. First-trimester PD and pre-eclampsia screening entail qualitative differences which alter the requirements for disclosure, non-directedness and consent with regard to the informed consent process. This article explores the differences related to the ethical issues raised by PD and pre-eclampsia in order to elucidate which factors are relevant to deciding the type of information and consent required in each context from the perspective of the ethical principles of beneficence and autonomy. Furthermore, it argues that ensuring respect for patient autonomy is context dependent and, consequently, pre-eclampsia screening and PD should be performed independently of one another.

Abstract
OBJECTIVE To study the risk of adverse pregnancy outcomes in women with polycystic ovary syndrome (PCOS), and to examine the role of hyperandrogenaemia. DESIGN Cohort study. SETTING Singleton pregnancies in women with PCOS identified at a private fertility clinic during 1997-2010 and a background population including all singleton deliveries at Hvidovre Hospital, Denmark, in 2005. POPULATION A cohort of 459 women with PCOS and a background population of 5409 women. METHODS Obstetric outcomes were extracted from national Danish registries and odds ratios (ORs) were calculated by multiple logistic regression analysis, adjusting for age, parity, and body mass index. MAIN OUTCOME MEASURES Risk of pre-eclampsia, preterm delivery, and small for gestational age offspring in the entire PCOS population and in a subsample with hyperandrogenaemia. RESULTS Women with PCOS had an increased risk of preterm delivery <37 weeks of gestation (OR 2.28; 95% confidence interval, 95% CI, 1.51-3.45; P < 0.0001). The elevated risk was confined to hyperandrogenic women with PCOS: preterm delivery before 37 weeks of gestation (OR 2.78; 95% CI 1.62-4.77; P < 0.0001), and was not seen in normoandrogenic women with PCOS (OR 1.35; 95% CI 0.54-3.39; P = 0.52). The overall risk of pre-eclampsia was not elevated (OR 1.69; 95% CI 0.99-2.88; P = 0.05) compared with the background population, but was significantly increased in the hyperandrogenic subsample (OR 2.41; 95% CI 1.26-4.58; P < 0.001). The risk of small for gestational age offspring was similar in all groups. CONCLUSION Women with PCOS had an increased risk of preterm delivery compared with the background population. The increased risk was confined to hyperandrogenic women with PCOS who had a two-fold increased risk of preterm delivery and pre-eclampsia.

Abstract
Pregnancy-associated plasma protein-A (PAPP-A) and PAPP-A2, two homologous metzincin metalloproteases, are both tightly linked to regulation within the insulin-like growth factor (IGF) system because of their specific cleavage of IGF binding proteins. Recent studies suggest that PAPP-A may be involved in clinical conditions related to unwanted cellular growth, and the circulating levels of PAPP-A is an established biomarker in prenatal screening for chromosomal abnormalities. Microarray data indicate that PAPP-A2 has potential as a biomarker for pre-eclampsia. However, well-characterized immunological methods of quantification are not available. We therefore developed monoclonal antibodies against recombinant PAPP-A2. The antibodies were epitope mapped against recombinantly expressed chimeras between PAPP-A2 and PAPP-A. Furthermore, circulating PAPP-A2 was immunoaffinity purified and characterized by sequence analysis and mass spectrometry. Unlike PAPP-A, PAPP-A2 is a noncovalent dimer in which each subunit of 1558 amino acids originates from all of the 22 predicted coding exons. A previously hypothesized variant (PAPP-E) does not exist, but low amounts of a C-terminally truncated PAPP-A2 variant was detected. A sensitive and robust ELISA for full-length PAPP-A2 was developed and used to establish normal ranges of PAPP-A2 through pregnancy. The functional sensitivity of this ELISA at 20% CV was 0.08 ng/ml, and the serum concentration of PAPP-A2 was found to increase during pregnancy in agreement with placental synthesis. The existence of this assay will enable an assessment of the biomarker potential of PAPP-A2 in pre-eclampsia as well as other clinical conditions.

Abstract
Prospective surveillance of Creutzfeldt–Jakob disease (CJD) was initiated in Denmark in 1997, following the observation of variant CJD in the United Kingdom. Demographic, clinical and diagnostic information was collected for each patient with clinical suspicion of CJD. Here we describe the methods for surveillance and the observed outcomes between 1 January 1997 and 31 December 2008. A total of 83 patients were classified as sporadic CJD, 47 were definite diagnoses, 34 probable and two possible. This resulted in a mean incidence of 1.26 patients with probable and definite sporadic CJD per million inhabitants. Two sporadic CJD patients were found to have a genetic variant of unknown significance: Thr201Ser and Glu200Asp. One patient was diagnosed with Gerstmann-Sträussler-Scheinker syndrome. No patients were classified as having variant, iatrogenic or familial CJD. The Danish surveillance system, like those in other countries, has a multidisciplinary approach, which is labour-intensive and time-consuming but ensures the most complete set of information possible. With this approach we think that patients with variant CJD would have been detected had they occurred in Denmark. Certain aspects of CJD surveillance need further discussion at European level and beyond, in order to find a balance between efficiency of the systems and accuracy of surveillance data.

Abstract
BACKGROUND The etiology of postoperative cognitive dysfunction (POCD) remains unclear but toxicity of anesthetic drugs and their metabolites could be important. We aimed to assess the possible association between POCD after propofol anesthesia and various phenotypes owing to polymorphisms in cytochrome P450 encoding genes. METHODS We included patients who underwent non-cardiac surgery under total intravenous anesthesia with propofol. POCD was identified using a neuropsychological test-battery administered preoperatively, one week, and three months after surgery. Genotyping of CYP2C19*2, *3, CYP2D6*3, *4, *5 and *6 was performed using pyrosequencing, and patients were characterized according to their phenotype as ultra, extensive, intermediate, or poor metabolizers. RESULTS In total, 337 patients with a median age of 67 years were included. 30 (9.4%) out of the 319 patients who underwent neuropsychological testing at one week had POCD, and 24 out of 307 (7.8%) had POCD at three months. None of the examined CYP2C19, 2D6 alleles, or various phenotypes were significantly associated with POCD. CONCLUSION Polymorphisms in CYP2C19, or 2D6 genes do not seem to be related to the occurrence of cognitive dysfunction after non-cardiac surgery in patients anesthetised with propofol.

Abstract
Background: Tau protein has been proposed as biomarker of axonal damage leading to irreversible neurological impairment in MS. CSF concentrations may be useful when determining risk of progression from ON to MS. Objective: To investigate the association between tau protein concentration and 14-3-3 protein in the cerebrospinal fluid (CSF) of patients with monosymptomatic optic neuritis (ON) versus patients with monosymptomatic onset who progressed to multiple sclerosis (MS). To evaluate results against data found in a complete literature review. Methods: A total of 66 patients with MS and/or ON from the Department of Neurology of Glostrup Hospital, University of Copenhagen, Denmark, were included. CSF samples were analysed for tau protein and 14-3-3 protein, and clinical and paraclinical information was obtained from medical records. Results: The study shows a significantly increased concentration of tau protein in CSF from patients with relapsing–remitting MS and patients monosymptomatic at onset who progressed to MS, but interestingly no increased tau protein concentration in monosymptomatic ON. The concentration of tau protein was significantly correlated to Expanded Disability Status Scale score. No 14-3-3 protein was detected in any CSF sample. Conclusions: The results of this study invite further exploration of the possible role of tau protein as a prognostic factor to predict progression from ON to MS in future studies.

Abstract
BACKGROUND Familial hypertrophic cardiomyopathy (HCM) has been described previously in British Shorthair cats (BSH), but until now, no reports have been published describing the prevalence of the disease within this breed. OBJECTIVES The aim of this study was to assess the prevalence of HCM in a large cohort of BSH and to evaluate the effect of sex, weight, and increasing age as potential risk factors for this disease. ANIMALS Three hundred and twenty-nine BSH presented for routine HCM screening during a 4-year period. METHODS Prospective cross-sectional study in which all cats were screened for HCM by conventional echocardiography. RESULTS A total of 329 cats were examined, 214 females and 115 males, with a median age of 2.3 years (range, 0.8-14.1). Twenty-eight cats (8.5%) were classified as HCM-positive, 14 (4.3%) as equivocal, 282 (85.7%) as HCM-negative, and 5 (2.1%) were diagnosed with other cardiac diseases. The median age for diagnosis of HCM was 2.7 years (range, 0.9-14.1). Male cats had a significantly higher occurrence of HCM (20.4%) compared with the females (2.1%) corresponding to an odds ratio of 7.89 (95 % CI, 2.54-28.08) for males versus females adjusted for age and weight (P < .001). CONCLUSION The BSH in our cohort had a high prevalence of HCM, often of early onset and with a significant male sex predisposition. We strongly recommend echocardiographic screening in this breed, especially cats used for breeding.

Abstract
OBJECTIVE To investigate if maternal levels of human placental lactogen (hPL), placental growth hormone (PGH) and insulin-like growth factor-1 (IGF-1) are associated with growth rate of the biparietal diameter (BPD) in the first half of pregnancy. METHODS Data on 8215 singleton fetuses from the Copenhagen First Trimester Study with measurements of BPD from ultrasound scans performed at weeks 11-14 and 17-21 of pregnancy were analyzed. Growth rate was defined as millimeters of growth/day of BPD between the two scans. Fetuses with growth rate below the 2.5(th) centile (low growth rate, n = 203) and above the 97.5(th) centile (high growth rate, n = 203) were identified. As a reference group 212 fetuses with growth rate around the median were identified (intermediate growth rate). Out of the 618 selected cases in the three growth rate groups a total of 463 cases had a blood sample taken at the time of first-trimester ultrasound (5.6% of the original sample size of 8215 pregnancies). The maternal blood serum concentrations of hPL, PGH and IGF-1 were determined in the three different growth-rate groups. Linear regression analysis without adjustment and with adjustment for known and potential confounders was used to compare serum levels between the groups. RESULTS Simple linear regression showed a difference in serum level of log(10) PGH between the high and intermediate growth-rate groups (P = 0.037). When adjusted for maternal weight and crown-rump length, multiple linear regression analysis confirmed this difference, as fetuses with high growth rates had a 12% (95% confidence interval, 2-20%; P = 0.009) higher maternal serum level of PGH than those with intermediate growth rates. No differences in hPL and IGF-1 levels between the three different growth-rate groups were found after simple and multiple linear regression analysis. CONCLUSION Maternal PGH levels are higher in women carrying fetuses with high first-trimester growth rates than in controls, both in a simple unadjusted analysis and in analyses adjusted for known and potential confounders. Thus, PGH may be involved in fetal growth regulation as early as in the first trimester of pregnancy.

Abstract
OBJECTIVE First trimester screening for fetal chromosomal disease is now possible using the maternal serological markers pregnancy-associated plasma protein-A (PAPP-A) and the free ss-form of human chorionic gonadotrophin (sshCG) in combination with the ultrasound marker nuchal translucency (NT) thickness. The availability of well-defined analytical methods and reference ranges for the involved parameters, and knowledge of the correlation between markers and clinical parameters, e.g. maternal weight, parity and age, are important for the design of efficient screening programs. MATERIAL AND METHODS Women (n = 2702), with singleton pregnancies, participating in the Copenhagen First Trimester Screening Study had PAPP-A and sshCG values determined and NT measured at a gestational age of 11 to 14 weeks, as determined from crown rump length (CRL). The distribution of gestational age-independent multiples of the median (MoM) of the parameters was defined and reference intervals established. Three methods for determination of PAPP-A, one manual in-house poly-monoclonal ELISA and two commercial semi-automatic double-monoclonal methods, i.e. PAPP-A for the AutoDelfia platform and PAPP-A for the Kryptor platform, were compared in 260 women. RESULTS All markers had log-normally distributed MoMs. Gestational age independent reference intervals were established. Maternal weight should be included in risk algorithms. The semi-automated PAPP-A assays (AutoDelfia and Kryptor) gave similar values, mean difference 10.5 %, whereas the manual assay gave higher values, mean differences 50.4 % and 41.0 %, respectively, CONCLUSIONS This calls for better standardization and a uniform quality control scheme that is focused on discriminatory ability rather than adherence to mean values from a large number of laboratories.

Abstract
OBJECTIVE Tetranectin (TN) is a glycoprotein and C-type lectin thought to play a prominent role in tissue remodelling. The aim of this study was to determine the TN serum and cerebrospinal fluid (CSF) concentration in patients with multiple sclerosis (MS) and controls. MATERIAL AND METHODS Two-hundred-and-four patients, divided into four diagnostic groups, i.e. definite MS (n = 76), possible onset symptoms of MS (n = 48), other non-inflammatory neurological diseases (n = 61) and other inflammatory neurological diseases (n = 19) and 47 controls with no history of neurological disease were analysed for TN in serum and CSF using a polyclonal sandwich ELISA. RESULTS All tested groups, e.g. definite MS, possible onset symptoms of MS, other neurological disease, both inflammatory and non-inflammatory, had decreased concentrations of TN in the CSF compared to the concentrations in controls. The quotient of TN in CSF divided by the concentration in serum (QTN) correlated significantly with the same quotient of albumin (QALB), was significantly correlated with the same quotient of albumin QALB. To account for differences in blood brain barrier permeability, we calculated a TN-index defined as: TN-index = QTN/QALB. QTN was significantly decreased in all groups compared to that in controls. However, in definite MS and patients with first attack of MS, the TN-index was not significantly different from that of controls. In contrast, other neurological diseases, both inflammatory and non-inflammatory, were associated with a decreased TN-index. CONCLUSION These results indicate that TN may play a role in neurological diseases and may serve as a diagnostic aid in MS.

Abstract
Pregnancy-associated plasma protein A (PAPP-A) is a maternal serum marker of fetal chromosomal disease and a risk marker for adverse outcome. PAPP-A in the circulation exists both as a 2:2 complex (PAPP-A/proMBP) with the proform of eosinophil major basic protein (proMBP) and as dimeric PAPP-A. Non-PAPP-A containing proMBP complexes constitute the bulk of proMBP in maternal serum. We developed and characterized a sandwich enzyme immunoassay for PAPP-A using a polyclonal rabbit anti-PAPP-A/proMBP antibody (SSI 6823) and a monoclonal murine anti-PAPP-A/proMBP antibody (HYB 234-3), reactive with the PAPP-A part of PAPP-A/proMBP. The assay range was 2 mIU/L-500 mIU/L, intra- and inter-assay coefficients of variation <10%. The immunoreactivity eluted ahead of thyroglobulin, Mr 669 kDa, in gel filtration and bound to a heparin column. Serum concentrations of PAPP-A were determined in gestational weeks 5-13 in 167 pregnant women with normal fetuses and 39 women with Down's syndrome (DS) fetuses. The median PAPP-A MoM (multiples of the median in normal controls) in DS pregnancies was 0.30 (quartile range: 0.17-0.54). The PAPP-A logMoMs in DS pregnancies were normally distributed with a mean of -0.5927 and SD of 0.3639. When simulating the performance of PAPP-A and age as markers for DS in population screening a detection rate (DR) of 62% was found for a screen positive rate (SPR) of 5%. Together with beta-HCG and nuchal translucency, two other first trimester markers for fetal DS, a DR 90% could be obtained for an SPR of 5%.

Abstract
Gc globulin, also called vitamin D-binding protein, is a plasma protein involved in the actin-scavenger system. In this study, the total Gc globulin concentration in serum or plasma samples was determined using a new, fast, solid-phase inhibition assay. Included in the study were 228 healthy volunteers (131 M, 97 F), 22 pregnant women, 90 cancer patients and 9 patients with chronic liver disease. Moreover, the degree of complexing with actin was determined in selected samples using crossed immunoelectrophoresis. The Gc globulin level in healthy controls was in the range 176-623 mg/L, showing no age dependency. The median level was found to be significantly higher in women than in men. Gc globulin concentrations were raised during pregnancy, showing a median value of 541 mg/L in the first trimester, and slightly raised to 574 mg/L in the second trimester. Cancer patients showed no changes in Gc globulin level, and there was no sign of increased amounts of complexing with actin. Chronic liver patients showed increased levels of Gc globulin following transplantation, but no signs of complexing with actin. This new solid-phase inhibition assay is fast, it is a good complement to the existing quantification methods, and it is especially suitable for determination of the Gc globulin status in acute liver patients before and during treatment.

Abstract
BACKGROUND Trauma has previously been shown to influence interleukin (IL)-6 and IL-10 levels, but the association of injury severity and mortality with IL-6 and IL-10 responses in the early phase of accidental trauma remains to be investigated. We wished to describe serum levels of IL-6 and IL-10 in the first 24 h after trauma and to assess the relationship with severity of injury and mortality. METHODS Prospective, descriptive cohort study in a Level 1 trauma centre, Copenhagen, Denmark. We included 265 consecutive adult trauma patients admitted directly from the accident scene during an 18-month period. Serum levels of IL-6 and IL-10 were measured upon arrival and at 6, 12, and 24 h after admittance using an enzyme-linked immunosorbent assay. Correlation analysis was used to assess the relationship between Injury Severity Score (ISS) and levels of IL-6 and IL-10. Analysis of variance was used to describe the IL-6 and IL-10 concentrations in relation to 30-day mortality in a mixed-effect model repeated measures analysis. RESULTS Mortality was 10.9% (29/265) at 30 days. A significant increase of both IL-6 and IL-10 concentrations was found over time, and a significant correlation was found between ISS and the levels of both IL-6 and IL-10 at all sampling points. Serum concentrations of IL-6 and IL-10 were significantly higher in patients not surviving 30 days (P<0.0001). CONCLUSION The early systemic inflammatory response measured as IL-6 and IL-10 in serum is correlated with injury severity and 30-day mortality following trauma.
