    Abstract Von Willebrand factor (VWF) is a multimeric plasma glycoprotein that plays a central role in the initiation of blood coagulation. Through interactions between its specific functional domains, the vascular wall, coagulation factor VIII, and platelet receptors, VWF maintains hemostasis by binding to platelets and delivering factor VIII to the sites of vascular injury. In the healthy human population, plasma VWF levels vary widely. The important role of VWF is illustrated by individuals at the extremes of the normal distribution of plasma VWF concentrations where individuals with low VWF levels are more likely to present with mucocutaneous bleeding. Conversely, people with high VWF levels are at higher risk for venous thromboembolic disease, stroke, and coronary artery disease. This report will summarize recent advances in our understanding of environmental influences and the genetic control of VWF plasma variation in healthy and symptomatic populations and will also highlight the unanswered questions that are currently driving this field of study.

    Abstract Purpose of review: New DNA genotyping and sequencing technologies have facilitated the rapid advancement in our knowledge of human genomic variation and a search for the heritable determinants of complex genetic traits. This review highlights findings from recent genetic studies of complex traits primarily related to venous thromboembolism and provides tools to understand and interpret genome-wide association studies and next-generation sequencing studies.
    Recent findings: Genome-wide studies of venous thromboembolic disease and the variation of the protein components of the hemostatic system have been reported. The results of these studies have suggested that variants in a diverse set of known and new genes contribute to the heritability of these traits, but that many of the genetic determinants of these traits still remain undiscovered.
    Summary: Next-generation sequencing studies and functional studies of the gene loci that contribute to hemostatic traits are currently underway. Future studies that explore the role of rare genetic variants, regulatory elements of the genome and gene-gene interactions will be required for a more complete understanding of the genetic control of the hemostatic system and for the application of this knowledge to the care of patients with disorders of thrombosis and hemostasis.

    Abstract Background: Glucagon-like peptide-1 (GLP-1) is a gut-derived peptide secreted in response to nutritional and inflammatory stimuli. Elevated GLP-1 levels predict adverse outcome in patients with acute myocardial infarction or sepsis. GLP-1 holds cardioprotective effects and GLP-1 receptor agonists reduce cardiovascular events in high-risk patients with diabetes. In this study, we aimed to investigate the capacity of GLP-1 to predict outcome in patients with cardiogenic shock (CS) complicating myocardial infarction.
    Methods: Circulating GLP-1 levels were serially assessed in 172 individuals during index PCI and day 2 in a prospectively planned biomarker substudy of the IABP-SHOCK II trial. All-cause mortality at short- (30 days), intermediate- (1 year), and long-term (6 years) follow-up was used for outcome assessment.
    Results: Patients with fatal short-term outcome (n = 70) exhibited higher GLP-1 levels [86 (interquartile range 45-130) pM] at ICU admission in comparison to patients with 30-day survival [48 (interquartile range 33-78) pM; p < 0.001] (n = 102). Repeated measures ANOVA revealed a significant interaction of GLP-1 dynamics from baseline to day 2 between survivors and non-survivors (p = 0.04). GLP-1 levels above vs. below the median proved to be predictive for short- [hazard ratio (HR) 2.43; 95% confidence interval (CI) 1.50-3.94; p < 0.001], intermediate- [HR 2.46; 95% CI 1.62-3.76; p < 0.001] and long-term [HR 2.12; 95% CI 1.44-3.11; p < 0.001] outcome by multivariate Cox-regression analysis.
    Conclusion: Elevated plasma levels of GLP-1 are an independent predictor for impaired prognosis in patients with myocardial infarction complicated by CS. The functional relevance of GLP-1 in this context is currently unknown and needs further investigations.

    Abstract Purpose/background: Glycine transporter-1 inhibitors may ameliorate cognitive deficits in schizophrenia. This study evaluated potential drug-drug interactions with the glycine transporter-1 inhibitor BI 425809.
    Methods/procedures: Interactions with cytochromes P450 (CYP) and P-glycoprotein (P-gp) were assessed in in vitro assays using human hepatocytes and Caco-2 cells, respectively. Pharmacokinetic characteristics of probe drugs were subsequently assessed in a Phase I, open-label, single-sequence crossover study in healthy male participants. Participants received a probe-drug cocktail containing midazolam (CYP3A4), warfarin (CYP2C9), and omeprazole (CYP2C19) and a separate dose of digoxin (P-gp), alone and on a background of steady-state BI 425809 25 mg once daily in 2 treatment periods. Adverse events were monitored.
    Findings/results: In vitro assays revealed concentration-dependent induction of CYP3A4 and inhibition of P-gp by BI 425809. In the clinical study, 12 of 13 participants completed both periods. With BI 425809, area under the plasma concentration curve from administration to the last measurement (AUC 0-tz ) and maximum plasma concentration ( Cmax ) for midazolam were lower than when administered alone. Adjusted geometric mean ratios (90% confidence interval) were 70.6% (63.9%-78.1%) for AUC 0-tz and 77.6% (67.3%-89.4%) for Cmax . For warfarin and digoxin, AUC 0-tz and Cmax were similar with and without BI 425809. For omeprazole, BI 425809 slightly reduced AUC 0-tz but not Cmax versus omeprazole alone. No new safety signals were identified.
    Implications/conclusions: These findings indicate induction of CYP3A4 by once-daily BI 425809 25 mg (the assumed highest therapeutic dose) and no meaningful effects on CYP2C9, CYP2C19, or P-gp in vivo.

    Abstract Background: Recent trials support the efficacy of renal sympathetic denervation (RDN) to reduce blood pressure (BP). Nevertheless, about one third of patients are considered non-responders to RDN. Previous retrospective analyses suggest arterial stiffness could predict BP response to RDN.
    Aims: We prospectively assessed the potential of invasive pulse wave velocity (iPWV) to predict BP response to RDN. Additionally, we aimed to establish non-invasive models based on arterial stiffness to predict BP response to RDN.
    Methods:  iPWV, magnetic resonance imaging-based markers of arterial stiffness and the carotid-femoral pulse wave velocity were recorded prior to RDN in patients with treatment resistant hypertension. Changes in daytime BP after 3 months were analysed according to the prespecified iPWV cut-off (14.4 m/s). Regression analyses were used to establish models for non-invasive prediction of BP response. Results were compared to iPWV as reference and were then validated in an external patient cohort.
    Results: Eighty patients underwent stiffness assessment before RDN. After 3 months, systolic 24h and daytime BP were reduced by 13.6±9.8 mmHg and 14.7±10.6 mmHg in patients with low iPWV, versus 6.2±13.3 mmHg and 6.3±12.8 mmHg in those with high iPWV (p<0.001 for both). Upon regression analysis, logarithmic ascending aortic distensibility and systolic baseline BP independently predicted BP change at follow-up. Both were confirmed in the validation cohort.
    Conclusions:  iPWV is an independent predictor for BP response after RDN. In addition, BP change prediction following RDN using non-invasive measures is feasible. This could facilitate patient selection for RDN treatment.

    Abstract This year's Congress of the International Society of Thrombosis and Haemostasis (ISTH) took place in person in Montréal, Canada, from June 24-28, 2023. The conference, held annually, highlighted cutting-edge advances in basic, translational, population and clinical sciences relevant to the Society. As for all ISTH congresses, we offered a special, congress-specific scientific theme; this year, the special theme was immunothrombosis. Certainly, over the last few years, COVID-19 infection and its related thrombotic and other complications have renewed interest in the concepts of thromboinflammation and immunothrombosis; namely, the relationship between inflammation, infection and clotting. Other main scientific themes of the Congress included Arterial Thromboembolism, Coagulation and Natural Anticoagulants, Diagnostics and Omics, Fibrinolysis and Proteolysis, Hemophilia and Rare Bleeding Disorders, Hemostatic System in Cancer, Inflammation and Immunity, Pediatrics, Platelet Disorders, von Willebrand Disease and Thrombotic Microangiopathies, Platelets and Megakaryocytes, Vascular Biology, Venous Thromboembolism and Women's Health. Among other sessions, the program included 28 State-of-the-Art (SOA) sessions with a total of 84 talks given by internationally recognized leaders in the field. SOA speakers were invited to prepare brief illustrated reviews of their talks that were peer reviewed and are included in this article. These illustrated capsules highlight the major scientific advances with potential to impact clinical practice. Readers are invited to take advantage of the excellent educational resource provided by these illustrated capsules. They are also encouraged to use the image in social media to draw attention to the high quality and impact of the science presented at the Congress.
