Abstract
Objective To screen a general pediatric population for type 1 diabetes (T1D), celiac disease (CD), and autoimmune thyroid disease (AITD) after home capillary sampling. Methods Swedish schoolchildren between 6-9 years and 13-16 years of age were invited to screening by taking a capillary sample at home. Samples were returned by mail and assessed for autoantibodies associated with T1D, CD, and AITD. Persistently autoantibody-positive children were referred for clinical follow-up. Results Of 19,593 invited, 3,527 (18.0%) consented to participate and 2,315/3,527 (65.6%) returned a blood sample of sufficient volume. Hemolysis occurred in 830/2,301 (36.1%) samples. After exclusion of 42 children with previously known T1D, CD, or AITD, and two autoantibody-positive children who declined a confirmatory sample, 2,271/19,593 (11.6%) were included. 211/2,271 (9.3%) had persistent autoantibodies: 60/2,271 (2.6%) with T1D autoantibodies, 61/2,271 (2.7%) with CD autoantibodies, and 99/2,271 (4.4%) with AITD autoantibodies; 9/2,271 (0.4%) were autoantibody positive for ≥1 disease. After clinical follow-up, 3/2,271 (0.1%) were diagnosed with T1D, 26/2,271 (1.1%) with CD, and 6/2,271 (0.3%) with AITD. Children with a first-degree relative (FDR) with T1D, CD, and/or AITD, had higher occurrence of autoantibodies compared to children without an FDR (63/344, 18.3%, vs. 148/1,810, 8.2%) (p < 0.0001, OR 2.52, 95% CI 1.83-3.47), and higher occurrence of screening-detected diagnosis (14/344, 4.1%, vs. 21/1,810, 1.2%) (p < 0.0001, OR 3.61, 95% CI 1.82-7.18). Half of these children screened positive for another disease than the FDR. Conclusion Screening for T1D, CD, and AITD by home capillary sampling in a Swedish general pediatric population detected autoimmunity in 9.3% and undiagnosed disease in 1.5%.

Abstract
BACKGROUND A minimal approach, using local anaesthesia alone, has been advocated to promote faster transcatheter aortic valve replacement (TAVR) procedures in intermediate-risk patients. Pre- and periprocedural anxiety and pain remain a concern. Virtual reality (VR) is a form of non-pharmacological distraction that can potentially modulate pain and anxiety. This randomised study explored whether VR reduces pain and anxiety during TAVR without sedation and compared the effects of VR with those of standard care. METHODS AND RESULTS Between June 2022 and March 2023, 207 patients underwent transfemoral TAVR (TF-TAVR). Of these, 117 (56.5%) patients were willing to participate in the study and met the educational background and mental status criteria for assessment. Fifty-nine patients underwent TF-TAVR with VR glasses (VR group). Fifty-eight patients underwent standard TF-TAVR without VR (control group; CG). Post-interventional anxiety scores (STAI-S) (31.5 ± 13.4 vs. 38.5 ± 19.2, p = 0.02) and the perceived duration of the procedure (60.1 ± 32.3 vs. 73.0 ± 32.4, p = 0.04) were lower in the VR than in the CG. Procedure time, pain, and anxiety scores (visual analogue scale) were similar between the groups. The complication rate was low and not associated with VR. Post-interventional delirium occurred in nine patients, and was similar between the groups (VR: 4 [6.8%] vs. CG: 5 [8.6%], p = 0.71). No periprocedural strokes were observed. CONCLUSION VR for TAVR is feasible and safe and expands the non-drug spectrum of therapy for anxiety and pain in patients undergoing TAVR with a minimalistic approach.

Abstract
Autoimmune thyroid disease (AITD) may be detected prior to clinical symptoms through the presence of autoantibodies against thyroid peroxidase (TPOab), thyroglobulin (TGab), or both.The present study aimed to develop a novel radiobinding assay (RBA) for TPOab and to determine the prevalence of TPOab and TGab in the Swedish population.Patient samples from 27 newly diagnosed Graves' disease patients in longitudinal follow-up and 124 AITD autoantibody-positive children in prospective follow-up for increased risk of type 1 diabetes were included to validate the novel RBA for TPO. The results of RBA were compared with those obtained by commercial radioimmunoassay (RIA) and electrochemiluminescence (ECL). Furthermore, 476 serum samples from adult blood donors and 297 from 13-year-old school children were analyzed for the presence of TPOab and TGab.Receiver operating characteristics analysis for the novel TPOab resulted in an area under curve (AUC) value of 0.82 (p<0.0001), a sensitivity of 77.8%, and a specificity of 91.9% in adult blood donors, and an AUC value of 0.70 (p<0.0001), a sensitivity of 53.2% and a specificity of 95.3% in the 13-year-old school children, respectively. TPOab levels in RBA correlated with both ECL (r=0.8950, p<0.0001) and RIA (r=0.9295, p<0.0001). The prevalence of TPOab and TGab was 6.3% and 7.6% in adult blood donors and 2.9 and 3.7% in 13-year-old school children.In conclusion, a novel RBA for the determination of TPOab was developed and validated with current methodologies. This study also reports an increasing prevalence of thyroid autoantibodies from adolescence to adulthood.

Abstract
Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and hyper-spectral imaging. Among the available spectroscopic approaches, GHz MIR dual-comb absorption spectrometers have the potential to simultaneously combine the high-speed, high spectral resolution, and broad optical bandwidth needed to accurately study complex, transient events in chemistry, combustion, and microscopy. However, such a spectrometer has not yet been demonstrated due to the lack of GHz MIR frequency combs with broad and full spectral coverage. Here, we introduce the first broadband MIR frequency comb laser platform at 1 GHz repetition rate that achieves spectral coverage from 3 to 13 µm. This frequency comb is based on a commercially available 1.56 µm mode-locked laser, robust all-fiber Er amplifiers and intra-pulse difference frequency generation (IP-DFG) of few-cycle pulses in χ(2) nonlinear crystals. When used in a dual comb spectroscopy (DCS) configuration, this source will simultaneously enable measurements with μs time resolution, 1 GHz (0.03 cm-1) spectral point spacing and a full bandwidth of >5 THz (>166 cm-1) anywhere within the MIR atmospheric windows. This represents a unique spectroscopic resource for characterizing fast and non-repetitive events that are currently inaccessible with other sources.

Abstract
Multiple sclerosis (MS) is a chronic neurological disease believed to be caused by autoimmune pathogenesis. The aetiology is likely explained by a complex interplay between inherited and environmental factors. Genetic investigations into MS have been conducted for over 50 years, yielding >100 associations to date. Globally, the strongest linkage is with the human leukocyte antigen (HLA) HLA-DRB5*01:01:01-DRB1*15:01:01-DQA1*01:02:01-DQB1*06:02:01 haplotype. Here, high-resolution sequencing of HLA was used to determine the alleles of DRB3, DRB4, DRB5, DRB1, DQA1, DQB1, DPA1 and DPB1 as well as their extended haplotypes and genotypes in 100 Swedish MS patients. Results were compared to 636 population controls. The heterogeneity in HLA associations with MS was demonstrated; among 100 patients, 69 extended HLA-DR-DQ genotypes were found. Three extended HLA-DR-DQ genotypes were found to be correlated to MS; HLA-DRB5*01:01:01-DRB1*15:01:01-DQA1*01:02:01-DQB1*06:02:01 haplotype together with (A) HLA-DRB4*01:01:01//DRB4*01:01:01:01-DRB1*07:01:01-DQA1*02:01//02:01:01-DQB1*02:02:01, (B) HLA-DRBX*null-DRB1*08:01:01-DQA1*04:01:01-DQB1*04:02:01, and (C) HLA-DRB3*01:01:02-DRB1*03:01:01-DQA1*05:01:01-DQB1*02:01:01. At the allelic level, HLA-DRB3*01:01:02 was considered protective against MS. However, when combined with HLA-DRB3*01:01:02-DRB1*03:01:01-DQA1*05:01:01-DQB1*02:01:01, this extended haplotype was considered a predisposing risk factor. This highlights the limitations as included with investigations of single alleles relative to those of extended haplotypes/genotypes. In conclusion, with 69 genotypes presented among 100 patients, high-resolution sequencing was conducted to underscore the wide polymorphisms present among MS patients. Additional studies in larger cohorts will be of importance to define MS among the patient group not associated with HLA-DRB5*01:01:01-DRB1*15:01:01-DQA1*01:02:01-DQB1*06:02:01.

Abstract
Background: The left subclavian artery (LSA) is an infrequently used alternative access route for patients with severe peripheral artery disease (PAD) in patients who underwent transcatheter aortic valve replacement (TAVR). We report a new endovascular approach for TAVR combining an axillary prosthetic conduit-based access technique with new-generation balloon-expandable TAVR prostheses. Methods and Results: Between January 2020 and December 2020, 251 patients underwent TAVR at the West German Heart and Vascular Center. Of these, 10 patients (3.9%) were deemed to be treated optimally by direct surgical exposure of the left or right axillary artery via a surgically adapted prosthetic conduit. All procedures were performed under general anesthesia. One procedural stroke occurred due to severe calcification of the aortic arch. No specific complications of the subclavian access site (vessel rupture, vertebral, or internal mammary ischemia) were reported. Two minor bleedings from the access site could be treated conservatively. No surgical revision was necessary. Conclusion: The axillary prosthetic conduit-based access technique using new-generation balloon-expandable valves allows safe and successful TAVR in a subgroup of patients with a high risk of procedural complications due to severe peripheral vascular disease. Considering the increasing number of patients referred for TAVR, this approach could represent an alternative for patients with limited access sites.

Abstract
BACKGROUND We aimed to evaluate the outcomes of transapical and transaortic transcatheter aortic valve replacement (TAVR) in high-risk patients who were not suitable for transfemoral access and had a logistic EuroSCORE-I ≥ 25% and Society of Thoracic Surgeons (STS) score >6%. 'STS/ACC TAVR In-Hospital Mortality Risk App' was evaluated. MATERIAL AND METHODS Between January 2016 and May 2020, 126 patients at very high risk for aortic valve replacement underwent transapical (n = 121) or transaortic (n = 5) transcatheter aortic valve replacement. TAVR was performed using SAPIEN 3™ or ACURATE TA™ prosthesis. RESULTS The logistic EuroSCORE-I was 40.6 ± 14.0%, the STS-score 7.9 ± 4.6%, and STS/ACC-score 8.4 ± 3.4%. Valve implantation was successful in all patients. Operative, in-hospital and 30-days mortality, were 0, 7.9, and 13.5%, respectively. Survival was 72% at one year and 48% at four years. Expected/observed in-hospital mortality was 1.0 for the STS-score and 1.06 for the STS/ACC-score. Renal failure, low ejection fraction, and postoperative acute kidney injury, hemorrhage, and vascular complications were identified as independent predictors for 30-day mortality. CONCLUSIONS Transapical and transaortic TAVR in high-risk patients unsuitable for transfemoral access is still a reasonable alternative in these patients. STS and STS/ACC-score appear to be highly accurate in predicting in-hospital mortality in high-risk patients undergoing TAVR.

Abstract
Background and Objectives: Permanent pacemaker implantation (PPI) is frequently required following transcatheter aortic valve replacement (TAVR). Dual antiplatelet therapy (DAPT) or oral anticoagulation therapy (OAK) is often necessary in these patients since they are at higher risk of thromboembolic events due to TAVR implantation, high incidence of coronary artery diseases (CAD) with the necessity of coronary intervention, and high rate of atrial fibrillation with the need of stroke prevention. We sought to evaluate the safety, efficiency, and clinical outcomes of early PPI following TAVR using the PlasmaBlade™ (Medtronic Inc., Minneapolis, MN, USA) pulsed electron avalanche knife (PEAK) for bleeding control in patients under DAPT or OAK. Materials and Methods: This retrospective single-center study included patients who underwent PPI after transfemoral TAVR (TF) at our center between December 2015 and May 2020. All PPI were performed using the PlasmaBlade™ Device. Results: The overall PPI rate was 14.1% (83 of 587 patients; 82.5 ± 4.6 years; 45.8% male). The PPI procedures were used to treat high-grade atrioventricular block (81.9%), severe sinus node dysfunction (13.3%), and alternating bundle branch block (4.8%). At the time of the procedure, 35 (42.2%) patients received DAPT, and 48 (57.8%) patients received OAK (50% with vitamin K antagonist (VKA) and 50% with novel oral anticoagulants (NOAK)). One device-pocket hematoma treated conservatively occurred in a patient (1.2%) receiving NOAK. Two re-operations were necessary in patients due to immediate lead dislocation (2.4%). Conclusions: The results of this study illustrate that the use of PlasmaBlade™ for PPI in patients after a TAVR who require antithrombotic treatment is feasible and might result into lower rates of severe bleeding complications compared to rates reported in the literature. Use of the PlasmaBlade device may be considered in this specific group of patients because of their high risk of bleeding.

Abstract
Background We sought to evaluate the outcomes of transapical transcatheter mitral valve replacement in patients with degenerated mitral bioprostheses or failed mitral ring annuloplasty and high surgical risk for redo mitral valve procedure. Methods Between August 2012 and December 2020, 41 consecutive high-risk patients underwent transcatheter mitral 'valve-in-valve' (TM-ViV, n=25) or 'valve-in-ring' (TM-ViR, n=16) implantation at our institution. All procedures were performed in a hybrid operating theater using the SAPIEN XT/3™ or the DIRECT FLOW MEDICAL™ prostheses. Data was collected prospectively according to MVARC criteria. Results The logistic EuroSCORE-I was 42.3%±20.5% (mean ± SD), the Society of Thoracic Surgeons (STS) score was 11.9%±10.8%, and the STS/ACC-score was 7.6%±4.2%. Transcatheter mitral valve implantations were successful in all patients (100%). Early echocardiographic examinations showed no obstruction of the left ventricular outflow tract (LVOT), no paravalvular leakage, and only trace transvalvular leakage in eight patients. There was no operative mortality; thirty-day mortality was 9.8%. Survival was 72% at one year and 63% at three years. At two-year follow-up, transvalvular mean pressure gradients were 4.6±1.4 mmHg. Conclusions Transapical transcatheter mitral valve-in-valve or valve-in-ring implantation represents a true minimally invasive alternative to surgical redo procedures, especially in high-risk patients with failed bioprosthetic mitral valves or annuloplasty and favorable anatomy.

Abstract
BACKGROUND Prognostic markers for disease severity and identification of therapeutic targets in COVID-19 are urgently needed. We have studied innate and adaptive immunity on protein and transcriptomic level in COVID-19 patients with different disease severity at admission and longitudinally during hospitalization. METHODS Peripheral blood mononuclear cells (PBMCs) were collected at three time points from 31 patients included in the Norwegian SARS-CoV-2 cohort study and analysed by flow cytometry and RNA sequencing. Patients were grouped as either mild/moderate (n = 14), severe (n = 11) or critical (n = 6) disease in accordance with WHO guidelines and compared with patients with SARS-CoV-2-negative bacterial sepsis (n = 5) and healthy controls (n = 10). RESULTS COVID-19 severity was characterized by decreased interleukin 7 receptor alpha chain (CD127) expression in naïve CD4 and CD8 T cells. Activation (CD25 and HLA-DR) and exhaustion (PD-1) markers on T cells were increased compared with controls, but comparable between COVID-19 severity groups. Non-classical monocytes and monocytic HLA-DR expression decreased whereas monocytic PD-L1 and CD142 expression increased with COVID-19 severity. RNA sequencing exhibited increased plasma B-cell activity in critical COVID-19 and yet predominantly reduced transcripts related to immune response pathways compared with milder disease. CONCLUSION Critical COVID-19 seems to be characterized by an immune profile of activated and exhausted T cells and monocytes. This immune phenotype may influence the capacity to mount an efficient T-cell immune response. Plasma B-cell activity and calprotectin were higher in critical COVID-19 while most transcripts related to immune functions were reduced, in particular affecting B cells. The potential of these cells as therapeutic targets in COVID-19 should be further explored.

Abstract
Background Transcatheter methods have been rapidly evolving to provide an alternative less invasive therapeutic option, mainly because redo patients often present with multiple comorbidities and high operative risk. We sought to evaluate and compare our experience with transapical transcatheter mitral valve replacement (TA-TMVR) to conventional redo mitral valve replacement in patients presenting with degenerated biological mitral valve prostheses or failed valve annuloplasty. Methods and material Between March 2012 and November 2020, 74 consecutive high-risk patients underwent surgical redo mitral valve replacement (n = 33) or TA-TMVR (n = 41) at our institution. All patients presented with a history of a surgical mitral valve procedure. All transcatheter procedures were performed using the SAPIEN XT/3™ prostheses. Data collection was prospectively according to MVARC criteria. Results The mean logistic EuroSCORE-II of the whole cohort was 19.9±16.7%, and the median STS-score was 11.1±12.5%. The mean age in the SMVR group was 63.7±12.8 years and in the TMVR group 73.6±9.7 years. Patients undergoing TA-TMVR presented with significantly higher risk scores. Echocardiography at follow up showed no obstruction of the left ventricular outflow tract, no paravalvular leakage and excellent transvalvular gradients in both groups (3.9±1.2 mmHg and 4.2±0.8 mmHg in the surgical and transcatheter arm respectively). There was no difference in postoperative major adverse events between the groups with no strokes in the whole cohort. Both methods showed similar survival rates at one year and a 30-day mortality of 15.2% and 9.8% in SAVR and TMVR group, respectively. Despite using contrast dye in the transcatheter group, the rate of postoperative acute kidney failure was similar between the groups. Conclusion Despite several contraindications for surgery, we showed the non-inferiority of TA-TMVR compared to conventional surgical redo procedures in high-risk patients. With its excellent hemodynamic and similar survival rate, TA-TMVR offers a feasible alternative to the conventional surgical redo procedure in selected patients.

Abstract
BACKGROUND A high proportion of COVID-19 patients have cardiac involvement, even those without known cardiac disease. Downregulation of angiotensin converting enzyme 2 (ACE2), a receptor for SARS-CoV-2 and the renin-angiotensin system, as well as inflammatory mechanisms have been suggested to play a role. ACE2 is abundant in the gut and associated with gut microbiota composition. We hypothesized that gut leakage of microbial products, and subsequent inflammasome activation could contribute to cardiac involvement in COVID-19 patients. METHODS Plasma levels of a gut leakage marker (LPS-binding protein, LBP), a marker of enterocyte damage (intestinal fatty acid binding protein, IFABP), a gut homing marker (CCL25, ligand for chemokine receptor CCR9) and markers of inflammasome activation (IL-1β, IL-18 and their regulatory proteins) were measured at three time points (day 1, 3-5 and 7-10) in 39 hospitalized COVID-19 patients and related to cardiac involvement. RESULTS Compared to controls, COVID-19 patients had elevated plasma levels of LBP and CCL25 but not IFABP, suggesting impaired gut barrier function and accentuated gut homing of T cells without excessive enterocyte damage. Levels of LBP were twice as high at baseline in patients with elevated cardiac markers compared with those without and remained elevated during hospitalization. Also, markers of inflammasome activation were moderately elevated in patients with cardiac involvement. LBP was associated with higher NT-pro-BNP levels, whereas IL-18, IL-18BP and IL-1Ra were associated with higher troponin levels. CONCLUSION Patients with cardiac involvement had elevated markers of gut leakage and inflammasome activation, suggestive of a potential gut-heart axis in COVID-19.

Abstract
An increased incidence of narcolepsy type 1 (NT1) was observed in Scandinavia following the 2009-2010 influenza Pandemrix vaccination. The association between NT1 and HLA-DQB1*06:02:01 supported the view of the vaccine as an etiological agent. A/H1N1 hemagglutinin (HA) is the main antigenic determinant of the host neutralization antibody response. Using two different immunoassays, the Luciferase Immunoprecipitation System (LIPS) and Radiobinding Assay (RBA), we investigated HA antibody levels and affinity in an exploratory and in a confirmatory cohort of Swedish NT1 patients and healthy controls vaccinated with Pandemrix. HA antibodies were increased in NT1 patients compared to controls in the exploratory (LIPS p = 0.0295, RBA p = 0.0369) but not in the confirmatory cohort (LIPS p = 0.55, RBA p = 0.625). HA antibody affinity, assessed by competition with Pandemrix vaccine, was comparable between patients and controls (LIPS: 48 vs. 39 ng/ml, p = 0.81; RBA: 472 vs. 491 ng/ml, p = 0.65). The LIPS assay also detected higher HA antibody titres as associated with HLA-DQB1*06:02:01 (p = 0.02). Our study shows that following Pandemrix vaccination, HA antibodies levels and affinity were comparable NT1 patients and controls and suggests that HA antibodies are unlikely to play a role in NT1 pathogenesis.

Abstract
INTRODUCTION Transcatheter aortic valve implantation (TAVI) techniques are increasingly being adopted into clinical routine for various risk groups. Coronary artery disease (CAD) is seen in up to 75% of patients with severe aortic valve stenosis (AS) presenting with typical angina pectoris. Due to high mortality rates and procedural complications in these patients, a hybrid concept of simultaneous transaortic TAVI and off-pump coronary artery bypass (OPCAB) can be a feasible treatment option. METHODS Between April 2014 and July 2020, 10 consecutive high-risk patients underwent concomitant transaortic TAVI and OPCAB at our institution. All indications were discussed in Heart Team and decisions were made based on patients' comorbidities and complexity of CAD. The study endpoints were 30-day mortality, device success, and development of postoperative adverse events defined by the Valve Academic Research Consorium. RESULTS The mean age of the patients was 77.9 ± 7.1 years old. All patients presented with multiple comorbidities (mean logistic EuroSCORE 26.5 ± 12.3%, median EuroSCORE II 5.13% [interquartile range 4.2-9.5], mean STS-Score 6.04 ± 1.6%). Five patients (50%) presented with porcelain aorta. No conversion to conventional procedures was needed. 30-day mortality occurred in one patient (10%). Complete revascularization was achieved in seven (70%) of the patients. Device success rate was 100%. No paravalvular leakage was detected. No stroke, myocardial infarction or vascular complications were observed. CONCLUSIONS A hybrid approach combining transaortic TAVI and OPCAB might be a safe and feasible method of treatment in high-risk patients presenting with severe AS and CAD who are not eligible for conventional surgical or interventional solutions.

Abstract
Background Patients with severe aortic stenosis (AS) often present with multiple comorbidities and suffer from critical coronary artery disease (CAD). Transcatheter aortic valve replacement (TAVR) has become the therapy of choice for moderate to high-risk patients. Venoarterial extracorporeal membrane oxygenation (v-a-ECMO) offers the possibility of temporary cardiac support to manage life-threatening critical situations. Case summary Here, we describe the management of a patient with severe AS and CAD with impaired left ventricular ejection fraction (LVEF). We used v-a-ECMO as an emergency strategy in cardiogenic shock during a high-risk coronary intervention to stabilize the patient, and as a further bridge to TAVR. Discussion Very high-risk patients with severe AS are unlikely to tolerate the added risk of surgical aortic valve replacement. Using ECMO may help them to benefit from TAVR as the only treatment option available.

Abstract
BACKGROUND Patients with atrial fibrillation (AF) are at high risk of thromboembolism, with most thrombi forming in the left atrial (LA) appendage. LA appendage closure is an alternative therapy to oral anticoagulation for stroke prevention in AF patients with contraindication to oral anticoagulation. LA function is critical for cardiovascular function, and recent studies suggested a direct relationship between LA function and AF recurrence. Deformation imaging characterizes and quantifies myocardial function. AIM This study aims to investigate the impact of LA appendage closure on LA function in patients with paroxysmal AF. METHODS We studied patients with paroxysmal AF who underwent LA appendage closure in a single-center, retrospective study. Twelve patients (CHA2DS2-VASc score, 4.12 ± 1.1; age, 75.9 ± 6.9 years; 7 men and 5 women) were eligible. Echocardiography-derived LA global longitudinal strain analysis, LA diameter, and LA volume index were determined before and after a 6-month follow-up. All patients were in sinus rhythm during echocardiography. The LA global longitudinal strain was unchanged after LA appendage closure (from -18.9 ± 2.8% to -19.6 ± 2.6%; P=.66). No changes were observed for LA size (from 49.1 ± 6.1 mm to 50.5 ± 5.2 mm; P=.45) or for LA volume index (from 51.6 ± 4.6 mL/m² to 52.1 ± 4.1 mL/m²; P=.49), corroborating unaltered LA function after LA appendage closure. CONCLUSION LA function is crucial for cardiovascular function and recurrence of AF. Our study provides evidence that LA appendage closure preserves LA function, determined by strain imaging in patients with paroxysmal AF and sinus rhythm during echocardiography.

Abstract
Background The use of transcatheter aortic valve replacement (TAVR) in cancer survivors and patients with active cancer (AC) in cancer survivors and patients with active cancer (AC) is expanding, suggesting a need to adjust the indications and risk assessment pre-TAVR. Objectives The purpose of this study was to determine the impact of cancer on peri-procedural complications and survival in a long-term, single-center cohort of patients treated with TAVR. Methods Patients treated with TAVR between January 2006 and December 2018 were grouped as follows: controls (patients without cancer), stable cancer (SC), and AC. The primary endpoints were peri-procedural complications and 30-day survival. A secondary endpoint was 10-year survival. Results A total of 1,088 patients (age 81 ± 5 years, 46.6% men) treated with transfemoral TAVR were selected: 839 controls, 196 SC, and 53 AC. Predominant malignancies were breast, gastrointestinal, and prostate cancer. No differences were observed between patients with cancer and controls regarding peri-procedural complications. Patients with AC had similar 30-day survival compared with controls and SC (94.3% vs. 93.3% vs. 96.9%, p = 0.161), but as expected, reduced 10-year survival. AC was associated with a 1.47 (95% CI 1.16 to 1.87) fold increased risk of all-cause 10-year mortality in multivariable adjusted models. Conclusions TAVR should be performed in patients with cancer when indicated, considering that patients with cancer have similar periprocedural complications and short-term survival compared with control patients. However, patients with AC have worse 10-year survival. Future studies are needed to define cancer-specific determinants of worse long-term survival.

Abstract
Background: The avoidance of prolonged hospital stay is a major goal in the management of transcatheter aortic valve implantation (TAVI) - medically and economically. Materials & methods: We compared the time range of the preprocedural length of stay in 2014/2015 with 2016/2017, after the implementation of the TAVI coordinator in 2016. This included restructured pathways for screening and pre-interventional diagnosis, performed examinations during the inpatient stay and major outcome variables. Results: After 2016, we observed a significant reduction in preprocedural length of stay (admission to procedure) compared with 2014/2015 (11.3 ± 7.9 vs 7.5 ± 5.6 days, p = 0.001). There was no difference in other major outcome variables. Conclusion: The introduction of the TAVI coordinator caused a shortening of preprocedural length of stay.

Abstract
Increased incidence of narcolepsy type 1 (NT1) was observed following Pandemrix®-vaccination, initiated as a preventive measure against the 2009 Influenza pandemic. Here, single cell analysis was conducted to suggest a lower number of CD8+ CD27+ T cells among these patients. These findings provide understanding into the autoimmune pathogenesis of NT1.

Abstract
Background Parameters that mark the timing of left ventricular (LV) reverse remodeling following transcatheter aortic valve replacement (TAVR) are incompletely defined. This study aims to identify the dynamics of LV strain derived from speckle tracking echocardiography in a cohort of patients with severe aortic stenosis (AS) who underwent TAVR and its correlation with postprocedural outcomes. Methods We selected 150 consecutive patients (82 ± 4 years old, STS score 6.4 ± 6.2) who underwent transfemoral TAVR between 07/2016 and 12/2017 at our tertiary care center. All patients were evaluated at baseline, 1 week after TAVR, and 3 months following TAVR. Results The global longitudinal strain (GLS) 1 week following TAVR was comparable to that at baseline (− 15,9 ± 4.3 vs − 16.8 ± 4.1; p = NS) but significantly improved at 3 months following TAVR (− 15.9 ± 4.3% vs. -19.5 ± 3.5%; p < 0.001). No significant changes in global circumferential strain (GCS) and global radial strain (GRS) were detectable. The ejection fraction was significantly improved 1 week after the TAVR procedure. The baseline GLS correlated directly with the complication rate (R = 0.36, p = 0.005). The linear regression analysis showed that the main predictors of the improvement in the GLS at 3 months in our cohort were baseline GRS and GCS. Conclusion GLS improves at 3 months after TAVR, while LV ejection fraction does not show a substantial change, signaling an early recovery of LV longitudinal function after the intervention. Additionally, GLS has a direct correlation with the postprocedural outcomes. GLS improvement might emerge as a valuable parameter for a tailored follow-up in TAVR patients.

Abstract
The outcome of transfemoral transcatheter aortic valve implantation (TF-TAVI) with a self-expanding (SEP) versus a balloon-expandable prosthesis (BEP) in patients with a reduced ejection fraction (rEF, ≤40%) has not been previously investigated. Patients with rEF have an increased risk of death after TF-TAVI compared to patients with a preserved ejection fraction (pEF), and prosthesis choice might influence the outcome of these patients. We, therefore, sought to compare all-cause mortality of patients with rEF using a SEP versus a BEP. We retrospectively analyzed data of 679 single-center TF-TAVI patients. Patients were censored at death or completion of 1-year follow-up, whichever occurred first. Patients with rEF (n = 141, 21%) had an increased 1-year mortality compared to patients with pEF (28% vs 19%, p = 0.007). SEP were implanted in 149 patients (49 with rEF, 33%), while BEP were implanted in 530 patients (92 with rEF, 17%). In patients with pEF, 1-year mortality was similar after SEP- and BEP-implantation (16% vs 19%, p = 0.516). In patients with rEF, however, 1-year mortality was higher after SEP- than after BEP-implantation (43% vs 21%, p = 0.004). These patients had a higher incidence of new permanent pacemaker implantation (26.5% vs 13%, p = 0.046) and paravalvular leak ≥II° (21% vs 10%, p = 0.07), but both factors could not explain the excess mortality after SEP-implantation in the multivariate analysis. In patients with rEF, the use of a SEP was an independent predictor of 1-year mortality (HR 2.44, 95% CI 1.27 to 4.27, p = 0.007). In conclusion, patients with rEF had a higher 1-year mortality after TF-TAVI when a SEP instead of a BEP was used.

Abstract
Narcolepsy type 1 (NT1) is a chronic sleep disorder caused by a specific loss of hypocretin-producing neurons. The incidence of NT1 increased in Sweden, Finland and Norway following Pandemrix®-vaccination, initiated to prevent the 2009 influenza pandemic. The pathogenesis of NT1 is poorly understood, and causal links to vaccination are yet to be clarified. The strong association with Human leukocyte antigen (HLA) DQB1*06:02 suggests an autoimmune pathogenesis, but proposed autoantigens remain controversial. We used a two-step approach to identify autoantigens in patients that acquired NT1 after Pandemrix®-vaccination. Using arrays of more than 9000 full-length human proteins, we screened the sera of 10 patients and 24 healthy subjects for autoantibodies. Identified candidate antigens were expressed in vitro to enable validation studies with radiobinding assays (RBA). The validation cohort included NT1 patients (n = 39), their first-degree relatives (FDR) (n = 66), population controls (n = 188), and disease controls representing multiple sclerosis (n = 100) and FDR to type 1 diabetes patients (n = 41). Reactivity towards previously suggested NT1 autoantigen candidates including Tribbles homolog 2, Prostaglandin D2 receptor, Hypocretin receptor 2 and α-MSH/proopiomelanocortin was not replicated in the protein array screen. By comparing case to control signals, three novel candidate autoantigens were identified in the protein array screen; LOC401464, PARP3 and FAM63B. However, the RBA did not confirm elevated reactivity towards either of these proteins. In summary, three putative autoantigens in NT1 were identified by protein array screening. Autoantibodies against these candidates could not be verified with independent methods. Further studies are warranted to identify hypothetical autoantigens related to the pathogenesis of Pandemrix®-induced NT1.

Abstract
BACKGROUND Patients with severe coronary artery disease (CAD), comorbidities, or impaired hemodynamics are at risk during percutaneous coronary interventions. The aim of the study was to investigate the safety and efficacy of a novel risk-stratification algorithm for high-risk coronary procedures. METHODS AND RESULTS We prospectively screened 1189 patients with CAD requiring revascularization (period 07/2017-06/2018). The algorithm was designed to select high-risk procedures. Patients with elevated risk (n = 150) were classified into 3 risk groups (high-risk intervention [HRI] I-III) and procedural management was adjusted according to HRI group. Overall, 55 patients were categorized as HRI I, 52 as HRI II, and 43 as HRI III. With increasing HRI-level, SYNTAX score increased (HRI I:15 ± 5% vs. HRI II:24 ± 8% vs. HRI III:34 ± 7%; p < 0.001), and ejection-fraction decreased (HRI I:48 ± 10% vs. HRI II:49 ± 10% vs. HRI III:40 ± 11%; p < 0.001). The primary endpoint (hemodynamic compromise requiring mechanical circulatory support [MCS] [HRI I/II], unsuccessful weaning from MCS in the catheterization laboratory[HRI III], or periprocedural death[HRI I-III]) occurred in no case. The secondary endpoint of hemodynamic deterioration occurred in 26% (n = 39) but did not result in hemodynamic instability due to the risk-adjusted procedural management. The composite endpoint of in-hospital major adverse cardiac and cerebrovascular events (death, new myocardial infarction, cerebrovascular accident) occurred in 4 patients (3%). CONCLUSIONS The novel algorithm is a safe team-based stratification method for the identification and management of patients undergoing high-risk coronary interventions.

Abstract
The incidence of narcolepsy type 1 (NT1) increased in Sweden following the 2009–2010 mass-vaccination with the influenza Pandemrix-vaccine. NT1 has been associated with Human leukocyte antigen (HLA) DQB1*06:02 but full high-resolution HLA-typing of all loci in vaccine-induced NT1 remains to be done. Therefore, here we performed HLA typing by sequencing HLA-DRB3, DRB4, DRB5, DRB1, DQA1, DQB1, DPA1 and DPB1 in 31 vaccine-associated NT1 patients and 66 of their first-degree relatives (FDR), and compared these data to 636 Swedish general population controls (GP). Previously reported disease-related alleles in the HLA-DRB5*01:01:01-DRB1*15:01:01-DQA1*01:02:01-DQB1*06:02:01extended haplotype were increased in NT1 patients (34/62 haplotypes, 54.8%) compared to GP (194/1272 haplotypes, 15.3%, p = 6.17E-16). Indeed, this extended haplotype was found in 30/31 patients (96.8%) and 178/636 GP (28.0%). In total, 15 alleles, four extended haplotypes, and six genotypes were found to be increased or decreased in frequency among NT1 patients compared to GP. Among subjects with the HLA-DRB5*01:01:01-DRB1*15:01:01-DQA1*01:02-DQB1*06:02 haplotype, a second DRB4*01:03:01-DRB1*04:01:01-DQA1*03:02//*03:03:01-DQB1*03:01:01 haplotype (p = 2.02E-2), but not homozygosity for DRB1*15:01:01-DQB1*06:02:01 (p = 7.49E-1) conferred association to NT1. Alleles with increased frequency in DQA1*01:02:01 (p = 1.07E-2) and DQA1*03:02//*03:03:01 (p = 3.26E-2), as well as with decreased frequency in DRB3*01:01:02 (p = 8.09E-3), DRB1*03:01:01 (p = 1.40E-2), and DQB1*02:01:01 (p = 1.40E-2) were found among patients compared to their FDR. High-resolution HLA sequencing in Pandemrix-associated NT1 confirmed the strong association with the DQB1*06:02:01-containing haplotype but also revealed an increased association to the not previously reported extended HLA-DRB4*01:03:01-DRB1*04:01:01-DQA1*03:02//*03:03:01-DQB1*03:01:01 haplotype. High-resolution HLA typing should prove useful in dissecting the immunological mechanisms of vaccination-associated NT1.

Abstract
Abstract
Background
Outcomes of transfemoral transcatheter aortic valve implantation (TF-TAVI) with a self-expanding (SEP) and a balloon-expandable prosthesis (BEP) seem to be comparable, though head-to-head comparisons, especially in certain patient subsets, are sparse. In addition, patients with a reduced left-ventricular ejection fraction (rEF, ≤40%) appear to be at higher risk for an increased mortality after TF-TAVI than patients with a preserved left-ventricular ejection fraction (pEF). As it remains unclear, whether outcomes of patients with rEF differ between TF-TAVI using SEP and BEP, we sought to compare all-cause mortality of patients with rEF using a SEP or a BEP.
Methods
We retrospectively analyzed data of 679 single-center TF-TAVI patients, which were stratified by baseline ejection fraction (rEF versus pEF) and type of implanted prosthesis (SEP versus BEP). Patients were censored at death or completion of 1-year follow-up, whichever occurred first.
Results
Twenty-one percent of patients had rEF, and these patients had a higher 1-year mortality compared to patients with pEF (28% vs. 19%, p=0.007). SEP were implanted in 149 patients (49 patients with rEF), while BEP were implanted in 538 patients (92 patients with rEF). All-cause 1-year mortality was similar after SEP- and BEP-implantation (16% vs 19%, p=0.516) in patients with pEF. In patients with rEF, however, 1-year mortality was higher after SEP- than after BEP-implantation (43% vs. 21%, p=0.004, see figure). Patients with rEF had a higher incidence of new permanent pacemaker implantation (26.5% vs. 13%, p=0.046) and paravalvular leak ≥2 (21% vs. 10%, p=0.07) after SEP- than after BEP-implantation, but both factors could not explain the excess mortality after SEP-implantation in multivariate analysis.
Conclusion
Patients with rEF had a higher 30-day and 1-year mortality after TF-TAVI when a SEP instead of a BEP was used. Further studies are needed to confirm and explain this finding.

Abstract
Abstract
Background
Distal stent graft induced new entry (dSINE) is a rare complication occurring in acute and chronic dissections after thoracic endovascular aortic repair (TEVAR) and is linked to a high reintervention rate. We analyzed potential predicting risk factors for dSINE and analyzed the long-term outcome in patients after reintervention.
Methods
In this single-center, retrospective study we evaluated patients after TEVAR and investigated possible predictors for dSINE development. Therefore, we used a multivariate analysis to test important interventional parameters such as distal oversizing (dOS), taper ratio (TR), angle between distal stent graft and aorta, acute dissection and stent graft length. Reinterventional characteristics were analyzed and further long-term follow-ups after reintervention evaluated.
Results
We analyzed 185 patients with acute (n=77) and chronic (n=108) dissections after TEVAR with a follow-up of 68.9±32.5 months. Within the follow-up period, 12 (6.5%) patients developed dSINE after a median time of 22.2±20.7 months. We identified acute dissection as a major predicting factor for dSINE development with a 15.8 times higher odds, followed by an increased dOS and TR. The reintervention rate was higher in the dSINE group (83% vs. 20%, p=0.001), but reinterventional results were mostly satisfying, including further freedom from reintervention and/or new endoleak development up to a mean follow-up of 60.7±54.8 months. No dSINE was seen in association to tapered stent grafts.
Conclusion
We found acute aortic dissection as a major predicting factor for dSINE development, followed by increased dOS and TR. The use of tapered stent grafts might be beneficial in cases with expected high dOS and TR. In rare cases with dSINE occurrence, reintervention is often required, but has a good prognosis even after years.

Abstract
Study objectives: Narcolepsy type 1 (NT1) is a chronic sleep disorder characterized by loss of hypocretin-producing neurons. Increased NT1 incidence was observed in Sweden following mass-vaccination with Pandemrix®. Genetic association to HLA DQB1*06:02 implies an autoimmune origin, but target autoantigen remains unknown. Candidate autoantigens for NT1 have previously been identified in solid-phase immunoassays, while autoantibodies against conformation-dependent epitopes are better detected in radiobinding assays. The aims are to determine autoantibody levels against nine candidate autoantigens representing (1) proteins of the hypocretin transmitter system; Preprohypocretin (ppHypocretin), Hypocretin peptides 1 and 2 (HCRT1 and HCRT2) and Hypocretin receptor 2 (HCRTR2); (2) proteins previously associated with NT1; Tribbles homologue 2 (TRIB2), Pro-opiomelanocortin/alpha-melanocyte-stimulating-hormone (POMC/α-MSH) and Prostaglandin D2 Receptor DP1 (DP1); (3) proteins suggested as autoantigens for multiple sclerosis (another HLA DQB1*06:02-associated neurological disease); ATP-dependent Inwardly Rectifying Potassium Channel Kir4.1 (KIR4.1) and Calcium-activated chloride channel Anoctamin 2 (ANO2). Methods: Serum from post-Pandemrix® NT1 patients (n = 31) and their healthy first-degree relatives (n = 66) were tested for autoantibody levels in radiobinding assays separating autoantibody bound from free labelled antigen with Protein A-Sepharose. 125I-labelled HCRT1 and HCRT2 were commercially available while 35S-methionine-labelled ppHypocretin, HCRTR2, TRIB2, α-MSH/POMC, DP1, KIR4.1 or ANO2 was prepared by in vitro transcription translation of respective cDNA. In-house standards were used to express data in arbitrary Units/ml (U/ml). Results: All radiolabelled autoantigens were detected in a concentration-dependent manner by respective standard sera. Levels of autoantibodies in the NT1 patients did not differ from healthy first-degree relatives in any of the nine candidate autoantigens. Conclusions: None of the nine labelled proteins proposed to be autoantigens were detected in the radiobinding assays for conformation-dependent autoantibodies. The results emphasise the need of further studies to identify autoantigen(s) and clarify the mechanisms in Pandemrix®-induced NT1.

Abstract
OBJECTIVES To evaluate the impact of baseline left ventricular ejection fraction (LVEF) and its interaction with low-gradient aortic stenosis (LGAS) on all-cause mortality after transfemoral aortic valve implantation (TF-TAVI). METHODS We reviewed mortality data of 624 consecutive single center TF-TAVI patients and categorized LVEF according to current ASE/EACVI recommendations (normal, mildly-, moderately-, and severely abnormal). RESULTS Baseline LVEF was normal in 336 (53.8%), mildly abnormal in 160 (25.6%), moderately abnormal in 91 (14.6%), and severely abnormal in 37 (5.9%) patients, and 1-year mortality was 19%, 17%, 23%, and 43% (P = 0.002), respectively. Patients with LGAS had a similar 1-year mortality compared to those without LGAS in groups with normal (19% vs 19%, P = 0.899) and mildly abnormal LVEF (16% vs 17%, P = 0.898). One-year mortality of patients with LGAS was significantly greater than in those without LGAS in presence of moderately abnormal LVEF (31% vs 11%, P = 0.022), and it was numerically greater than in those without LGAS in presence of severely abnormal LVEF (48% vs 25%, P = 0.219). In multivariate analysis, only the combination of moderately/severely abnormal LVEF and LGAS predicted increased 1-year mortality (HR: 2.12, 95% CI: 1.4-3.2, P < 0.001). Other variables, including EuroSCORE I did not affect this result. CONCLUSIONS Moderately/severely abnormal LVEF (≤40%) at baseline is associated with increased mortality after TF-TAVI, especially when the mean transvalvular aortic gradient is <40 mm Hg (LGAS), while outcomes in patients with normal and mildly abnormal LVEF are comparable regardless of the pressure gradient across the native aortic valve.

Abstract
Background Transcatheter aortic valve implantation (TAVI) is the standard therapy for high-risk patients with aortic stenosis (AS). TAVI-outcomes are widely investigated in comparison to surgical aortic valve replacement (SAVR), but less is known about infectious complications after TAVI. We aimed to compare early and mid-term infectious outcomes of patients undergoing TAVI or SAVR. Methods The present study is a prospective single-centre study including 200 consecutive patients between 06/2014-03/2015 undergoing TAVI (either transfemoral or transapical and transaortic, n=47+53=100) or SAVR (either isolated or concomitant with CABG, n=52+48=100). The mean age and log. EuroSCORE were significantly different between both groups (81±6 versus 69±11 years, P<0.001 and 23.1%±13.8% versus 8.7%±9.5%, P<0.001). Primary endpoints included wound healing disorders, respiratory and urinary tract infections and incidence of endocarditis or sepsis within hospital stay. Secondary endpoints included infectious parameters, infectious related rehospitalisation and 2-year mortality. Results Primary endpoints showed no difference in overall TAVI- versus SAVR-groups regarding respiratory- (14% versus 19%, P=0.45), urinary-tract (7% versus 4%, P=0.54) infections, sepsis (5% versus 6%, P=1.0), endocarditis (0% versus 1%, P=1.0) or 30-day mortality (10% versus 4%, P=0.09), except for wound disorders, which were significantly lower in the TAVI-group (1% versus 8%, P=0.035), respectively. Secondary endpoints reported no difference regarding infectious related rehospitalisation (4% versus 4%, P=1.0), but significantly higher 2-year mortality (28% versus 16%, P=0.048) in the TAVI-group. Conclusions So far, little has been studied about infectious complications after TAVI. This study reports no difference between the overall TAVI and SAVR groups regarding infectious complications. However, SAVR group show more wound healing disorders but less mortality than TAVI group.

Abstract
Background Precise stent graft sizing in Thoracic endovascular aortic repair (TEVAR) is crucial to receive optimal long-term results. Computed tomography (CT), as the current standard in assessing aortic diameters (ADs), is often performed at initial diagnosis. Since several acute aortic diseases are associated with blood loss and/or volume re-distribution, assessed AD might be influenced by impaired hemodynamic conditions. Intravascular ultrasound (IVUS) offers real-time assessment, especially after hemodynamic restoration, and might help for stent graft choice. Methods We investigated the correlation between CT and later IVUS measurements in elective (n=83) and emergency patients (n=32) at the level distal to the left subclavian artery (LSA), a frequent proximal landing zone in TEVAR. Patients were grouped depending on their shock index (heart rate/systolic blood pressure): emergency patients with diagnosis of acute aortic syndrome, urgently required treatment after admission and had a shock index >1, otherwise were grouped as elective. Basic hemodynamics were assessed for both groups at admission and at definite IVUS-procedure. Results At time of admission the emergency group showed lower blood pressure (99±19.8 vs. 141±24 mmHg; P=0.001) and higher heart rate (98±13 vs. 70±12 bpm; P=0.001) compared to elective patients. By hemodynamic stabilization comparable blood pressure and heart rate were achieved in both groups at time of IVUS. In the emergency group, we found a significantly increase in AD after hemodynamic stabilization, whereas the diameters did not change in the elective group (IVUSmeanvs. CTmean: 5.1±1.0 vs. 0.4±2.2 mm; P=0.001 and IVUSminvs. CTmean: 3.9±1.3 vs. -0.3±2.2 mm; P=0.011). Conclusions IVUS for stent graft sizing is a valuable approach during TEVAR, especially in the light of emergency treatment by offering real-time assistance. Impaired hemodynamic conditions might lead to relevant changes in AD and may strongly influence stent graft choice. In these cases, careful stent graft selection might contribute to avoidance of stent graft related complication.

Abstract
BACKGROUND Autoimmune (type 1) diabetes (T1D) is a frequent chronic disease in children and adolescents globally. Gestational enterovirus (EV) infections have been associated with an increased risk for T1D in the offspring. We test the hypothesis that EV infections during the first trimester were associated with beta cell autoantibodies in mothers of children who developed islet autoantibodies before 7 years of age. MATERIALS AND METHODS Local registries were used to identify mothers to children born 2000-2007 who developed either beta cell autoantibodies or T1D during follow up. Serum samples from the first trimester were located in the Biobank. A total of 448 index mothers were identified and compared to 891 matched control mothers. EV-IgM was determined in a capture enzyme immunoassay. Beta cell autoantibodies were analyzed in standard radio binding assays. RESULTS The frequency of EV-IgM in index mothers was 20% (89/448), which did not differ from the control mothers 20% (175/891) (p = 0.922). Index mothers had multiple beta cell autoantibodies more often than control mothers (p = 0.037). Beta cell autoantibodies were increased during the November-April winter months in index compared to control mothers (p = 0.022). The observed difference was possibly explained by the months of February-April (p = 0.014). Concomitant EV-IgM and beta cell autoantibodies tended to be more common among index compared to control mothers (p = 0.039). CONCLUSION EV-IgM during the first trimester may be associated with beta cell autoantibodies in mothers to children who developed either beta cell autoantibodies or T1D before 7 years of age.

Abstract
Transcatheter aortic valve implantation (TAVI) has evolved to a treatment of choice in high-risk patients and is therefore ideal for patients with advanced chronic kidney disease, as patients with end-stage renal disease and kidney transplant recipients. Especially, outcome of this special patient group is very important. 22 patients with chronic kidney disease stage 5 undergoing intermittent hemodialysis treatment (CKD 5D) and 8 kidney transplant recipients (KT) with severe aortic valve stenosis underwent transfemoral TAVI. TAVI was successfully performed in all patients. Postinterventional acute kidney injury (AKI) occurred in four kidney transplant recipients (KDIGO grade 1: n = 3, grade 3: n = 1) but creatinine/eGFR returned to baseline values in all patients. Short-term (30-day) mortality was 3% (1 patient in CKD 5D group). KT had a higher 2-year mortality than CKD5D patients (31% vs. 53%; p = 0.309), and cause of death was non-cardiac because of sepsis in all cases. The amount of contrast medium during TAVI was not associated with the development of acute kidney injury. TAVI is feasible in patients with CKD5D and in KT. Postinterventional AKI in these patients is often mild and does not impact renal function at day 30, while infection/ sepsis is the leading cause of mid-term mortality.

Abstract
Infective endocarditis is an endovascular infection usually caused by bacteria. Mortality rate is still approximately 20 %. To improve patients' prognosis by implementation of current diagnostic and therapeutic evidence, the European Society of Cardiology published an updated version of the guidelines for management of infective endocarditis in 2015. It strengthens the role of imaging modalities like PET/CT for detection of infectious foci when echocardiography remains negative and highlights the use of modern tests for identification of possible pathogens. New diagnostic criteria were introduced to integrate these methods for improved diagnostic sensitivity. Complicated cases should be treated in reference centers with on-site cardiac surgery. The antibiotic and early surgical management should be discussed in a multidisciplinary endocarditis team. A few years ago, the indication for endocarditis prophylaxis was limited to high-risk patients. These recommendations were confirmed in current guidelines.

Abstract
Increased narcolepsy incidence was observed in Sweden following the 2009 influenza vaccination with Pandemrix®. A substitution of the 2009 nucleoprotein for the 1934 variant has been implicated in narcolepsy development. The aims were to determine (a) antibody levels toward wild-type A/H1N1-2009[A/California/04/2009(H1N1)] (NP-CA2009) and Pandemrix-[A/Puerto Rico/8/1934(H1N1)] (NP-PR1934) nucleoproteins in 43 patients and 64 age-matched controls; (b) antibody affinity in reciprocal competitive assays in 11 childhood narcolepsy patients compared with 21 age-matched controls; and (c) antibody levels toward wild-type A/H1N1-2009[A/California/04/2009(H1N1)] (H1N1 NS1), not a component of the Pandemrix vaccine. In vitro transcribed and translated 35S-methionine-labeled H1N1 influenza A virus proteins were used in radiobinding reciprocal competition assays to estimate antibody levels and affinity (Kd). Childhood patients had higher NP-CA2009 (p = 0.0339) and NP-PR1934 (p = 0.0246) antibody levels compared with age-matched controls. These childhood controls had lower NP-CA2009 (p = 0.0221) and NP-PR1934 (p = 0.00619) antibodies compared with controls 13 years or older. In contrast, in patients 13 years or older, the levels of NP-PR1934 (p = 0.279) and NP-CA2009 (p = 0.0644) antibodies did not differ from the older controls. Childhood antibody affinity (Kd) against NP-CA2009 was comparable between controls (68 ng/mL) and patients (74 ng/mL; p = 0.21) with NP-CA2009 and NP-PR1934 displacement (controls: 165 ng/mL; patients: 199 ng/mL; p = 0.48). In contrast, antibody affinity against NP-PR1934 was higher in controls with either NP-PR1934 (controls: 9 ng/mL; patients: 20 ng/mL; p = 0.0031) or NP-CA2009 (controls: 14 ng/mL; patients: 23 ng/mL; p = 0.0048). A/H1N1-NS1 antibodies were detected in 0/43 of the narcolepsy patients compared with 3/64 (4.7%) controls (p = 0.272). Similarly, none (0/11) of the childhood patients and 1/21 (4.8%) of the childhood controls had A/H1N1-NS1 antibodies. The higher antibody affinities against NP-PR1934 in controls suggest better protection against wild-type virus. In contrast, the reduced NP-PR1934 antibody affinities among childhood narcolepsy patients suggest poor protection from the wild-type A/H1N1 virus and possibly increased risk for viral damage.

Abstract
N-terminally truncated (96-585) GAD65 (tGAD65) autoantibodies may better delineate type 1 diabetes than full-length GAD65 (fGAD65) autoantibodies. We aimed to compare the diagnostic sensitivity and specificity between fGAD65 and tGAD65 autoantibodies for type 1 diabetes in relation to HLA-DQ. Sera from children and adolescents with newly diagnosed type 1 diabetes (n = 654) and healthy control subjects (n = 605) were analyzed in radiobinding assays for fGAD65 (fGADA), tGAD65 (tGADA), and commercial 125I-GAD65 (RSRGADA) autoantibodies. The diagnostic sensitivity and specificity in the receiver operating characteristic curve did not differ between fGADA and tGADA. At the optimal cutoff, the diagnostic sensitivity for fGADA was lower than tGADA at similar diagnostic specificities. In 619 patients, 64% were positive for RSRGADA compared with 68% for fGADA and 74% for tGADA. Using non-DQ2/non-DQ8 patients as reference, the risk of being diagnosed with fGADA and tGADA was increased in patients with DQ2/2 and DQ2/8. Notably, logistic regression analysis suggested that DQ8/8 patients had an increased risk to be diagnosed with tGADA (P = 0.003) compared with fGADA (P = 0.09). tGADA had a higher diagnostic sensitivity for type 1 diabetes than both fGADA and RSRGADA. As DQ8/8 patients represent 10-11% of patients with newly diagnosed type 1 diabetes <18 years of age, tGADA analysis should prove useful for disease classification.

Abstract
UNLABELLED It is unclear what the predictive value of very early development of gestures and language is on later language ability in prematurely born very-low-birth-weight (VLBW; birth weight ≤1500g) children. The aim of the present study was to analyse the predictive value of early gestures and a receptive lexicon measured between the ages of 0;9 and 1;3, as well as the predictive value of receptive and expressive language ability at 2;0 for language skills at 5;0 in VLBW children. The subjects were 29 VLBW children and 28 full-term children whose language development has been followed intensively between the ages of 0;9 and 2;0 using the Finnish version of the MacArthur Developmental Inventory and the Reynell Developmental Language Scales (RDLS III). At 5;0, five selected verbal subtests of the Nepsy II test and the Boston Naming Test (BNT) were used to assess children's language skills. For the first time in VLBW children, the development of gestures measured between the ages of 0;9 and 1;3 was shown to correlate significantly and positively with language skills at 5;0. In addition, both receptive and expressive language ability measured at 2;0 correlated significantly and positively with later language skills in both groups. Moreover, according to the hierarchical regression analysis, the receptive language score of the RDLS III at 2;0 was a clear and significant predictor for language skills at 5;0 in both groups. The findings particularly underline the role of early receptive language as a significant predictor for later language ability in VLBW children. The results provide evidence for a continuity between early language development and later language skills. LEARNING OUTCOMES After reading this article, readers will understand the associations between the very early (≤2 years of age) development of gestures and language (i.e. early receptive lexicon, expressive lexicon at 2;0, receptive and expressive language ability at 2;0) and the language skills at 5;0 in prematurely born very-low-birth-weight (VLBW) children. In addition, readers will understand the heterogeneity of the group of VLBW children. The information presented in this article is informative for those who work in a clinical context and who want to be able to identify those VLBW children who need support for their language development at an early age.

Abstract
BACKGROUND AND AIM OF THE STUDY The aim of this prospective study was to determine the impact of plasma B-type natriuretic peptide (BNP) on long-term outcome in patients undergoing transcatheter aortic valve implantation (TAVI). METHODS TAVI was performed either transfemorally or transaxillary using either the CoreValve prosthesis or Edwards SAPIEN prosthesis in 226 patients with symptomatic severe aortic valve stenosis and at high surgical risk. The examinations included measurements of plasma BNP and echocardiography before and at 30 days after TAVI. The primary study end-point was death from any cause after TAVI; the secondary end-point was defined as cardiovascular death. RESULTS During a mean follow up of 728 ± 549 days, 72 patients died; 52 deaths were cardiovascular-related. Those patients who died had higher preprocedural plasma BNP levels compared to those who survived (1,305 ± 1,238 pg/ml versus 716 ± 954 pg/ml; p < 0.001). Plasma BNP was the strongest independent predictor of all-cause mortality (BNP > 475 pg/ml, hazard risk [HR] 3.049; 95% confidence interval [CI] 1.804-5.151; p < 0.001) and cardiovascular mortality (BNP > 475 pg/ml, HR 3.479; 95% CI 1.817-6.662; p < 0.001). In surviving patients, plasma BNP levels were decreased by 30 days after TAVI (pre-TAVI 874 ± 1,122 pg/ml; post TAVI 471 ± 569 pg/ml; p < 0.001). A plasma BNP level > 328 pg/ml at 30 days postoperatively was also associated with all-cause mortality (HR 8.125; 95% CI 3.097-21.318; p < 0.001). CONCLUSION In patients undergoing TAVI, plasma BNP is the strongest independent predictor of all-cause mortality and cardiovascular mortality. Plasma BNP levels at 30 days after TAVI may provide prognostic information that should, potentially, lead to a more intensive therapy of these patients.

Abstract
There is little known about the long-term results of the CoreValve prosthesis. The aim of this study was to assess the 3-year clinical and hemodynamic outcomes of the CoreValve prosthesis. One hundred fifty consecutive patients with severe aortic stenosis successfully underwent transcatheter aortic valve implantation (TAVI) with the CoreValve prosthesis. The primary study end point was death from any cause after TAVI. The secondary end points were defined as (1) cardiovascular death and (2) prosthesis-related mortality and morbidity. At 1 to 3 years, all-cause mortality rates were 25%, 32%, and 41%, respectively, and cardiovascular mortality rates were 14%, 21%, and 27%, respectively. Before TAVI, 95% of patients were in New York Heart Association class III or IV. Of the surviving patients, rates of New York Heart Association class III or IV at 1 to 3 years were 33%, 39%, and 38%, respectively. There was an annual decrease of the valve area of approximately 0.1 cm². Aortic restenosis occurred in 2 patients. Moderate or severe aortic regurgitation (AR) occurred in 15% of patients immediately after TAVI. Twenty patients (13%) had a slight worsening of AR within 3 years. New severe AR did not occur. The incidence of prosthesis-related endocarditis was 0.66% per year. Overall, 7 patients (incidence of 1.5% per year) had a clinically relevant problem of the prosthesis. In conclusion, TAVI with the CoreValve prosthesis had favorable effects on symptoms and outcomes even after 3 years. These results are clouded by side effects, such as AR and prosthesis-related mortality and morbidity.

Abstract
Narcolepsy is a lifelong sleep disorder related to hypocretin deficiency resulting from a specific loss of hypocretin-producing neurons in the lateral hypothalamic area. The disease is thought to be autoimmune due to a strong association with HLA-DQB1*06:02. In 2009 the World Health Organization (WHO) declared the H1N1 2009 flu pandemic (A/H1N1PDM09). In response to this, the Swedish vaccination campaign began in October of the same year, using the influenza vaccine Pandemrix(®). A few months later an excess of narcolepsy cases was observed. It is still unclear to what extent the vaccination campaign affected humoral autoimmunity associated with narcolepsy. We studied 47 patients with narcolepsy (6-69 years of age) and 80 healthy controls (3-61 years of age) selected after the Pandemrix vaccination campaign. The first aim was to determine antibodies against A/H1N1 and autoantibodies to Tribbles homolog 2 (TRIB2), a narcolepsy autoantigen candidate as well as to GAD65 and IA-2 as disease specificity controls. The second aim was to test if levels and frequencies of these antibodies and autoantibodies were associated with HLA-DQB1*06:02. In vitro transcribed and translated [(35)S]-methionine and -cysteine-labeled influenza A virus (A/California/04/2009/(H1N1)) segment 4 hemagglutinin was used to detect antibodies in a radiobinding assay. Autoantibodies to TRIB2, GAD65 and IA-2 were similarly detected in standard radiobinding assays. The narcolepsy patients had higher median levels of A/H1N1 antibodies than the controls (p = 0.006). A/H1N1 antibody levels were higher among the <13 years old (n = 12) compared to patients who were older than 30 years (n = 12, p = 0.014). Being HLA-DQB1*06:02 positive was associated with higher A/H1N1 antibody levels in both patients and controls (p = 0.026). Serum autoantibody levels to TRIB2 were low overall and high binders did not differ between patients and controls. We observed an association between levels of A/H1N1 antibodies and TRIB2 autoantibody levels particularly among the youngest narcolepsy patients (r = 0.819, p < 0.001). In conclusion, following the 2009 influenza pandemic vaccination, A/H1N1 antibody levels were associated with young age-at-onset narcolepsy patients positive for HLA-DQB1*06:02. The possibility that TRIB2 is an autoantigen in narcolepsy remains to be clarified. We could verify autoantibody responses against TRIB2 which needs to be determined in larger patient cohorts and control populations.

Abstract
Background Patients with human immunodeficiency virus (HIV) infection have an increased risk of cardiovascular diseases. Previous publications described pericardial effusion as one of the most common HlV-associated cardiac affiliations. The aim of the current study was to investigate if pericardial effusion still has a relevant meaning of HIV-infected patients in the era of antiretroviral therapy. Methods The HIV-HEART (HIV-infection and HEART disease) study is a cardiology driven, prospective and multicenter cohort study. Outpatients with a known HIV-infection were recruited during a 20 month period in a consecutive manner from September 2004 to May 2006. The study comprehends classic parameters of HIV-infection, comprising CD4-cell count (cluster of differentiation) and virus load, as well as non-invasive tests of cardiac diseases, including a thorough transthoracic echocardiography. Results 802 HIV-infected patients (female: 16.6%) with a mean age of 44.2 ± 10.3 years, were included. Duration of HIV-infection since initial diagnosis was 7.6 ± 5.8 years. Of all participants, 85.2% received antiretroviral therapy. Virus load was detectable in 34.4% and CD4 - cell count was in 12.4% less than 200 cells/μL. Pericardial effusions were present in only two patients of the analysed population. None of the participants had signs of a relevant cardiovascular impairment by pericardial effusion. Conclusions Our results demonstrate that the era of antiretroviral therapy goes along with low rates of pericardial effusions in HIV-infected outpatients. Our findings are in contrast to the results of publications, performed before the common use of antiretroviral therapy.

Abstract
AIM To assess the long-term developmental outcome of very low birth weight children with postnatally developing caudothalamic cysts. METHODS Five very low birth weight children with postnatal caudothalamic cysts were examined using cranial ultrasound and brain Magnetic Resonance Imaging as neonates, the Bayley Scales of Infant Development, 2nd edition, and the Hammersmith Infant Neurological Examination at 2 years of corrected age, and with the Wechsler Preschool and Primary Scale of Intelligence-Revised and the standardization version of NEPSY II at 5 years of age. The Magnetic Resonance Imaging of the brain was repeated at 5 years of age. The developmental outcome at 5 years of age was compared with that of 23 very low birth weight children with normal brain structure. RESULTS A cognitive level below normal and/or neuropsychological impairments was seen in all the children with caudothalamic cysts as well as in those with normal brain structure. CONCLUSION Very low birth weight children with postnatally developing caudothalamic cysts had cognitive and neuropsychological impairments similar to very low birth weight children without such cysts.
