Evaluating the predictive role of endothelial dysfunction in the development of vasculopathy-mediated complications in patients with limited cutaneous systemic sclerosis (lcSSc). 38 patients with lcSSc who were naïve for vasculopathy-mediated complications, defined as absent pre-existing digital ulcers (DU), pulmonary hypertension (PH) and symptomatic atherosclerotic cardiovascular diseases, were prospectively observed during a 3-years follow-up period. At study enrolment, functional and laboratory parameters of endothelial dysfunction were assessed.

Critical limb threatening ischemia (CLTI) is associated with a one-year mortality rate of up to 25% making prompt diagnosis essentially. This study aims to investigate if cardiac biomarkers may serve as an effective tool for risk stratification in patients with lower extremity artery disease (LEAD). For this cross-sectional retrospective analysis, 21712 patients with LEAD were screened for eligibility from 2004 to 2020.

Article Synopsis
  • - The study examined the potential impact of lipoprotein (a) [Lp(a)] on the severity of venous thromboembolic events in pulmonary embolism (PE) by analyzing 90 patients and their Lp(a) levels.
  • - Results indicated that Lp(a) levels did not correlate with the thrombus load or location in PE, suggesting it may not significantly influence the extent of venous thromboembolism.
  • - The study found a strong correlation between thrombus load and D-dimer levels, as well as the right to left ventricular diameter ratio, implying these factors might be more relevant in assessing PE severity.

Purpose Of Review: This review aims to summarize the current state of the art and future directions in optimal long-term anticoagulation following acute pulmonary embolism (PE).

Recent Findings: Actual studies and guidelines underscore the preference for direct oral anticoagulants (DOAC) in standard therapeutic doses for maintenance therapy post-PE, while considering patient-specific factors and dose-reduction criteria. Risk stratification should always include the assessment of concomitant trigger- or risk factors regarding their strength and persistence.

People with diabetes have an increased risk of experiencing adverse COVID-19 outcomes. COVID-19 vaccination is, therefore, highly recommended. However, people with diabetes have an inherently elevated risk of thrombotic events and the impact of the vaccination on the coagulation system in this patient population remains to be elucidated.

Background: The aim of this single-center combined prospective/retrospective cohort study was to analyze Gadolinium (Gd)-enhanced MRA (magnetic resonance angiography) and MRV (MR venography) for the diagnosis of pulmonary artery embolism and deep venous thrombosis. The gold standard methods result in major exposure to radiation and a high amount of nephrotoxic iodinated contrast media. This is the first larger contrast-enhanced MR imaging study of acute and chronic venous thromboembolic disease of various stages.

Article Synopsis
  • COVID-19 vaccines were rapidly developed following the pandemic's onset, with cases of unusual thrombotic complications appearing soon after, particularly with adenoviral vector vaccines like those from AstraZeneca and Johnson & Johnson.
  • These complications, known as vaccine-induced thrombotic thrombocytopenia (VITT), involve rare thrombotic events paired with low platelet counts and share similarities with heparin-induced thrombocytopenia (HIT).
  • The review focuses on providing an overview of how to diagnose and treat these complications, noting that standard treatment for other thrombotic events may be harmful in these cases.

Article Synopsis
  • The study aimed to explore the relationship between the severity of pulmonary embolism (PE) and levels of lipoprotein (a) [Lp(a)] in patients at the University Hospital Graz, Austria.
  • A retrospective analysis of 811 PE patients was conducted, categorizing them into four risk groups based on the 2019 ESC guidelines: low risk, intermediate low risk, intermediate high risk, and high risk.
  • The research found no significant correlation between PE severity and Lp(a) levels, as similar median Lp(a) concentrations were observed across all risk groups.

Rising data suggest that COVID-19 affects vascular endothelium while the underlying mechanisms promoting COVID-19-associated endothelial dysfunction and inflammatory vasculopathy are largely unknown. The aim was to evaluate the contribution of COVID-19 to persisting vascular injury and to identify parameters linked to COVID-19-associated endothelial dysfunction and inflammatory vasculopathy. In a cross-sectional design, flow-mediated dilation (FMD), nitroglycerine-related dilation (NMD), pulse-wave velocity (PWV), augmentation index, intima-media thickness (IMT), compounds of the arginine and kynurenine metabolism, homocysteine, von Willebrand factor (vWF), endothelial microparticles (EMP), antiendothelial cell antibodies, inflammatory, and immunological parameters, as well as nailfold capillary morphology were measured in post-COVID-19 patients, patients with atherosclerotic cardiovascular diseases (ASCVD) and healthy controls without prior or recent SARS-CoV-2 infection.

Soluble urokinase plasminogen activator receptor (suPAR) is an inflammatory biomarker and risk factor for kidney diseases, with a potential prognostic value in critically ill patients. In this monocentric prospective study, we measured plasma suPAR levels immediately after ICU admission in unselected 237 consecutive patients using a turbidimetric assay. Primary objective was the prognostic value for ICU- and 28-day mortality.

Unlabelled: Background: The white blood cell count to mean platelet volume ratio (WMR) is increasingly gaining importance as a promising prognostic marker in atherosclerotic disease, but data on lower extremity artery disease (LEAD) are not yet available. The principle aim of this study was to assess the association of the WMR with the occurrence of CLTI (chronic limb-threatening ischemia) as the most advanced stage of disease.

Methods: This study was performed as a retrospective analysis on 2121 patients with a diagnosis of LEAD.

Objectives: Early diagnosis of invasive aspergillosis (IA) remains challenging, with available diagnostics being limited by inadequate sensitivities and specificities. Triacetylfusarinine C, a fungal siderophore that has been shown to accumulate in urine in animal models, is a potential new biomarker for diagnosis of IA.

Methods: We developed a method allowing absolute and matrix-independent mass spectrometric quantification of TAFC.

Mean platelet volume (MPV) was recently published as a possible marker of coronary artery disease in patients at high risk for major adverse cardiac events. Because platelets play an important role in atherosclerosis, we examined the relationship between critical limb ischemia (CLI) and MPV in patients with peripheral arterial occlusive disease (PAOD). Our study comprised 2124 PAOD patients.

Nearly 20% of patients will need non-cardiac surgery within 1 year of coronary stenting and their management is complicated by concomitant antiplatelet therapy. Platelet function testing may optimize the timing of surgery in these patients. In this prospective observational study, we explored the association between platelet reactivity and bleeding in patients undergoing non-cardiac surgery treated with clopidogrel with or without aspirin within 7 days before surgery.
