Sex differences in temporal trends in main and secondary pulmonary embolism diagnosis and case fatality rates: 2003-2019.

Aims: There is controversy regarding the incidence and outcomes of pulmonary embolism (PE) according to sex. Our aim was to address sex differences in temporal trends in main and secondary hospital PE diagnoses, management and case fatality rates (CFR).

Methods And Results: Retrospective analysis of Spain´s National Healthcare System hospital database, years 2003-2019, for patients ≥18 years with main or secondary PE diagnosis.

Multicentric Standardization of Protocols for the Diagnosis of Human Mitochondrial Respiratory Chain Defects.

The quantification of mitochondrial respiratory chain (MRC) enzymatic activities is essential for diagnosis of a wide range of mitochondrial diseases, ranging from inherited defects to secondary dysfunctions. MRC lesion is frequently linked to extended cell damage through the generation of proton leak or oxidative stress, threatening organ viability and patient health. However, the intrinsic challenge of a methodological setup and the high variability in measuring MRC enzymatic activities represents a major obstacle for comparative analysis amongst institutions.

Circadian rhythms in thrombosis and atherothrombotic events.

Biological circadian rhythms in living organisms are regulated by molecular clocks. Several of these clocks are present in blood vessels, peripheral tissues, and immune cells. There is strong evidence linking dysregulation of circadian rhythms to the development of cardiovascular disease.

Acute Heart Failure in the 2021 ESC Heart Failure Guidelines: a scientific statement from the Association for Acute CardioVascular Care (ACVC) of the European Society of Cardiology.

The current European Society of Cardiology (ESC) Heart Failure Guidelines are the most comprehensive ESC document covering heart failure to date; however, the section focused on acute heart failure remains relatively too concise. Although several topics are more extensively covered than in previous versions, including some specific therapies, monitoring and disposition in the hospital, and the management of cardiogenic shock, the lack of high-quality evidence in acute, emergency, and critical care scenarios, poses a challenge for providing evidence-based recommendations, in particular when by comparison the data for chronic heart failure is so extensive. The paucity of evidence and specific recommendations for the general approach and management of acute heart failure in the emergency department is particularly relevant, because this is the setting where most acute heart failure patients are initially diagnosed and stabilized.

Metformin reduces macrophage HIF1α-dependent proinflammatory signaling to restore brown adipocyte function in vitro.

Therapeutic potential of metformin in obese/diabetic patients has been associated to its ability to combat insulin resistance. However, it remains largely unknown the signaling pathways involved and whether some cell types are particularly relevant for its beneficial effects. M1-activation of macrophages by bacterial lipopolysaccharide (LPS) promotes a paracrine activation of hypoxia-inducible factor-1α (HIF1α) in brown adipocytes which reduces insulin signaling and glucose uptake, as well as β-adrenergic sensitivity.

Diabetes Mellitus and Its Implications in Aortic Stenosis Patients.

Aortic stenosis (AS) and diabetes mellitus (DM) are both progressive diseases that if left untreated, result in significant morbidity and mortality. Several studies revealed that the prevalence of DM is substantially higher in patients with AS and, thus, the progression from mild to severe AS is greater in those patients with DM. DM and common comorbidities associated with both diseases, DM and AS, increase patient management complexity and make aortic valve replacement the only effective treatment.

Glycated Hemoglobin and Subclinical Atherosclerosis in People Without Diabetes.

Background: The metabolic injury caused by protein glycation, monitored as the level of glycated hemoglobin (HbA1c), is not represented in most risk scores (i.e., Systematic Coronary Risk Estimation or atherosclerotic cardiovascular disease risk scale).

Composition, structure, and function of heart teams: a joint position paper of the ACVC, EAPCI, EACTS, and EACTA focused on the management of patients with complex coronary artery disease requiring myocardial revascularization.

Contemporary cardiovascular medicine is complex, dynamic, and interactive. Therefore, multidisciplinary dialogue between different specialists is required to deliver optimal and patient-centred care. This has led to the concept of explicit collaborations of different specialists caring for patients with complex cardiovascular diseases-that is 'heart teams'.

Contemporary economic burden in a real-world heart failure population with Commercial and Medicare supplemental plans.

Background: Limited real-world data exist on healthcare resource utilization (HCRU) and associated costs of patients with heart failure (HF) with reduced ejection fraction (HFrEF) and preserved EF (HFpEF), including urgent HF visits, which are assumed to be less burdensome than HF hospitalizations (hHFs) HYPOTHESIS: This study aimed to quantify the economic burden of HFrEF and HFpEF, via a retrospective, longitudinal cohort study, using IBM® linked claims/electronic health records (Commercial and Medicare Supplemental data only).

Methods: Adult patients, indexed on HF diagnosis (ICD-10-CM: I50.x) from July 2012 through June 2018, with 6-month minimum baseline period and varying follow-up, were classified as HFrEF (I50.

Venous lactate improves the prediction of in-hospital adverse outcomes in normotensive pulmonary embolism.

Background: Arterial lactate is an established risk marker in patients with pulmonary embolism (PE). However, its clinical applicability is limited by the need of an arterial puncture. In contrast, venous lactate can easily be measured from blood samples obtained via routine peripheral venepuncture.

2020 Update of the quality indicators for acute myocardial infarction: a position paper of the Association for Acute Cardiovascular Care: the study group for quality indicators from the ACVC and the NSTE-ACS guideline group.

Aims: Quality indicators (QIs) are tools to improve the delivery of evidence-base medicine. In 2017, the European Society of Cardiology (ESC) Association for Acute Cardiovascular Care (ACVC) developed a set of QIs for acute myocardial infarction (AMI), which have been evaluated at national and international levels and across different populations. However, an update of these QIs is needed in light of the accumulated experience and the changes in the supporting evidence.

Number of Antithrombotic Drugs Used Early and In-hospital Outcomes in Acute Coronary Syndromes.

Antithrombotic drug use for acute coronary syndromes (ACS) varies considerably. The number of antithrombotic drugs (excluding oral anticoagulants) used pre- and in-hospital was recorded in ACS survivors enrolled at hospital discharge in the long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients (EPICOR) registry ( NCT01171404 ), a prospective cohort study. Among 10,568 patients, the number of antithrombotic drugs used early/patient ranged from 0 to 8 (interquartile range = 3-4).

Diagnosis, prevention, and management of delirium in the intensive cardiac care unit.

Delirium is a frequent complication in patients admitted to intensive cardiac care units (ICCU) with potentially severe consequences including increased risks of mortality, cognitive impairment and dependence at discharge, and longer times on mechanical ventilation and hospital stay. Delirium has been widely documented and studied in general intensive care units and in patients after cardiac surgery, but it has barely been studied in acute nonsurgical cardiac patients. Moreover, delirium (especially in its hypoactive form) is commonly misdiagnosed.

Patient Management in Aortic Stenosis: Towards Precision Medicine Through Protein Analysis, Imaging and Diagnostic Tests.

Aortic stenosis is the most frequent valvular disease in developed countries. It progresses from mild fibrocalcific leaflet changes to a more severe leaflet calcification at the end stages of the disease. Unfortunately, symptoms of aortic stenosis are unspecific and only appear when it is too late, complicating patients' management.

Diagnosis and risk stratification of chest pain patients in the emergency department: focus on acute coronary syndromes. A position paper of the Acute Cardiovascular Care Association.

This paper provides an update on the European Society of Cardiology task force report on the management of chest pain. Its main purpose is to provide an update on the decision algorithms and diagnostic pathways to be used in the emergency department for the assessment and triage of patients with chest pain symptoms suggestive of acute coronary syndromes.

Reboxetine Treatment Reduces Neuroinflammation and Neurodegeneration in the 5xFAD Mouse Model of Alzheimer's Disease: Role of CCL2.

The reduction of brain noradrenaline levels is associated to the initiation of Alzheimer's disease and contributes to its progression. This seems to be due mainly to the anti-neuroinflammatory actions of noradrenaline. The analysis of noradrenaline effects on brain cells demonstrates that it also regulates the production of the chemokine CCL2.

Vascular Inflammation in Subclinical Atherosclerosis Detected by Hybrid PET/MRI.

Background: Atherosclerosis is a chronic inflammatory disease, but data on arterial inflammation at early stages is limited.

Objectives: The purpose of this study was to characterize vascular inflammation by hybrid F-fluorodeoxyglucose (F-FDG) positron emission tomography/magnetic resonance imaging (PET/MRI).

Methods: Carotid, aortic, and ilio-femoral F-FDG PET/MRI was performed in 755 individuals (age 40 to 54 years; 83.

Alternative Method to Detect Neuronal Degeneration and Amyloid β Accumulation in Free-Floating Brain Sections With Fluoro-Jade.

Fluoro-Jade is a fluorescein-derived fluorochrome which specifically binds to damaged neurons. Due to this characteristic, it is commonly used for the histochemical detection and quantification of neurodegeneration in mounted brain sections. Here, we describe an alternative and simpler histochemistry protocol based on the use of free-floating brain sections.
