Uremic toxins activate CREB/ATF1 in endothelial cells related to chronic kidney disease.

Uremic toxins, such as p-cresyl sulfate (PCS) and indoxyl sulfate (IS), contribute to endothelial dysfunction in chronic kidney disease (CKD). This process is mediated by several cellular pathways, but it is unclear whether cAMP-responsive element-binding protein (CREB) and activating transcription factor 1 (ATF1) participate in endothelial dysfunction in uremic conditions despite playing roles in inflammatory modulation. This study aimed to evaluate the expression, activation, and transcriptional activity of CREB/ATF1 in endothelial cells exposed to PCS, IS, and uremic serum (US).

Uremic endothelial-derived extracellular vesicles: Mechanisms of formation and their role in cell adhesion, cell migration, inflammation, and oxidative stress.

p-Cresyl sulfate (PCS), indoxyl sulfate (IS), and inorganic phosphate (Pi) are uremic toxins found in chronic kidney disease (CKD) that are closely related to endothelial extracellular vesicles (EVs) formation. The present study aimed to understand the role of EVs and their role in cell adhesion and migration, inflammation, and oxidative stress. Human endothelial cells were treated with PCS, IS, and Pi in pre-established uremic and kinetic recommendations.

Endothelial Microparticles in Uremia: Biomarkers and Potential Therapeutic Targets.

Endothelial microparticles (EMPs) are vesicles derived from cell membranes, which contain outsourced phosphatidylserine and express adhesion molecules, such as cadherin, intercellular cell adhesion molecule-1 (ICAM-1), E-selectin, and integrins. EMPs are expressed under physiological conditions and continue circulating in the plasma. However, in pathologic conditions their levels increase, and they assume a pro-inflammatory and pro-coagulant role via interactions with monocytes; these effects are related to the development of atherosclerosis.

Cardiac Prevention and Rehabilitation "3.0": From acute to chronic phase. Position Paper of the ltalian Association for Cardiovascular Prevention and Rehabilitation (GICR-IACPR).

Cardiac rehabilitation (CR) is the subspecialty of clinical cardiology dedicated to the treatment of cardiac patients, early and in the long term after an acute event. The aim of CR is to improve both quality of life and prognosis through prognostic stratification, clinical stabilization and optimization of therapy (pharmacological and non), management of comorbidities, treatment of disability, as well as through the provision and reinforcement of secondary prevention interventions and maintenaince of adherence to treatment. The mission of CR has changed over time.

[Treatment adherence in cardiovascular prevention].

Treatment adherence is a key element for (i) improving prognosis in cardiovascular and/or high-risk patients, (ii) reducing the burden of morbidity and mortality associated with cardiovascular disease at a population level, and (iii) decreasing costs due to rehospitalizations.Promotion of adherence should embrace all pharmacological and non-pharmacological interventions in cardiovascular prevention, including lifestyle and behavioral changes. In this perspective, cardiac prevention and rehabilitation programs are the most appropriate and cost-effective setting for delivering structured and multi-component interventions on patient's adherence.

[Cardiac rehabilitation "3.0": from the acute to the chronic stage. A position paper from the Italian Association for Cardiovascular Prevention and Rehabilitation (GICR-IACPR)].

Cardiac rehabilitation (CR) represents a cardiology subspecialty that is devoted to the care of cardiac patients, early and long term after an acute event. CR aims at improving both quality of life and prognosis through risk and prognostic stratification, clinical stabilization and optimization of therapy, management of comorbidities, treatment of disability, and the provision of sustained long-term preventive and rehabilitative services.The mission of CR has changed over time.

Sevelamer reduces endothelial inflammatory response to advanced glycation end products.

Background: Advanced glycation end products (AGEs) have been related to the pathogenesis of cardiovascular diseases (CVD), chronic kidney disease (CKD) and diabetes mellitus. We sought to investigate the binding capacity of sevelamer to both AGEs and uremic serum and then test this pharmaceutical effect as a potential vascular anti-inflammatory strategy.

Methods: AGEs were prepared by albumin glycation and characterized by absorbance and electrophoresis.

Prevalence and management of familial hypercholesterolemia in patients with coronary artery disease: The heredity survey.

Background And Aims: Familial hypercholesterolemia (FH) is a genetic disorder characterized by high levels of low density lipoprotein cholesterol (LDL-C) predisposing to premature cardiovascular disease. Its prevalence varies and has been estimated around 1 in 200-500. The Heredity survey evaluated the prevalence of potential FH and the therapeutic approaches among patients with established coronary artery disease (CAD) or peripheral artery disease (PAD) in which it is less well documented.

ANMCO Position Paper: long-term follow-up of patients with pulmonary thromboembolism.

Venous thromboembolism (VTE), including pulmonary embolism and deep venous thrombosis, is the third most common cause of cardiovascular death. The management of the acute phase of VTE has already been described in several guidelines. However, the management of the follow-up (FU) of these patients has been poorly defined.

[Heart rate as a therapeutic target after acute coronary syndrome and in chronic coronary heart disease].

For patients with stable coronary artery disease (SCAD), either after hospitalization for acute cardiac events or in the chronic phase, comprehensive treatment programs should be devoted to: (i) reducing mortality and major adverse cardiovascular events, (ii) reducing the ischemic burden and related symptoms, and (iii) increasing exercise capacity and quality of life.Heart rate (HR) has demonstrated to have prognostic value and patients beyond the limit of 70 bpm display increased risk of all the above adverse outcomes, even after adjustment for parameters such as the extension of myocardial infarction and the presence of heart failure. It is well known that a sustained HR elevation may contribute to the pathogenesis of SCAD, being the likelihood of developing ischemia, plaque instability, trigger for arrhythmias, increased vascular oxidative stress, and endothelial dysfunction the mechanisms resulting in this effect.

Role of Organic Anion Transporters in the Uptake of Protein-Bound Uremic Toxins by Human Endothelial Cells and Monocyte Chemoattractant Protein-1 Expression.

Organic anion transporters (OATs) are involved in the uptake of uremic toxins such as p-cresyl sulfate (PCS) and indoxyl sulfate (IS), which play a role in endothelial dysfunction in patients with chronic kidney diseases (CKD). In this study, we investigated the role of OAT1 and OAT3 in the uptake of PCS and IS into human endothelial cells. PCS was synthesized via p-cresol sulfation and characterized using analytical methods.

[A rare cardiomegaly].

We present the case of a patient who came to our attention for enlargement of the cardiac silhouette on chest X-ray. Echocardiography showed moderate diastolic overload of both ventricles with enhanced cardiac output without valvular disease or cardiac shunt that could account for this cardiomegaly. A subsequent abdominal echocardiographic exploration showed an angiomatous transformation of the liver due to diffuse lacunar enlargement of hepatic portal vein branches and arterial-venous shunts.

[ANMCO Position paper: Recommendations for the follow-up of patients with pulmonary thromboembolism].

Venous thromboembolism (VTE), including deep venous thrombosis and pulmonary embolism, is the third most common cause of cardiovascular death. The management of the acute phase of VTE is well described in several papers and guidelines, whereas the management of the follow-up of the patients affected from VTE is less defined. This position paper of the Italian Association of Hospital Cardiologists (ANMCO) tries to fill the gap using currently available evidence and the opinion of the experts to suggest the most useful way to manage patients in the chronic phase.

[The Italian Survey on Cardiac Rehabilitation - 2013 (ISYDE.13-Directory): national availability and organization of cardiac rehabilitation facilities].

Background: The Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (GICR-IACPR) and the Italian Society of Cardiologists of Accredited Hospitals (SICOA) developed the ISYDE.13 survey with the purpose to take a detailed snapshot of number, distribution, facilities, staffing levels, organization, and program details of cardiac rehabilitation (CR) units in Italy.

Depression is associated with increased vagal withdrawal during unpleasant emotional imagery after cardiac surgery.

Background: The aim of this study was to examine the influence of depression on heart rate and heart rate variability (HRV) during emotional imagery in patients after cardiac surgery.

Methods: Based on the scores of the Center for Epidemiological Studies of Depression (CES-D) scale, 28 patients after cardiac surgery were assigned either to the group with depression (CES-D scores ≥ 16; N = 14) or the one without depression (CES-D scores<16; N = 14). Each patient completed a rest period and an emotional imagery including pleasant, neutral and unpleasant scripts.

[Diagnosis and therapy of pulmonary arterial hypertension in Italy: results of the INCIPIT2 survey].

Background: Pulmonary arterial hypertension (PAH) is a rare clinical condition characterized by increased pulmonary vascular resistance and premature death. It is necessary to activate a pathway from the screening of pulmonary hypertension to the diagnosis of PAH, so as to use the drugs able to improve the outcome. Nowadays, in Italy, there are no data about the management of PAH in peripheral centers and about the integration of peripheral centers with those of excellence.

[Unexpected early obstruction of a biological aortic valve prosthesis].

A 64 years old male was submitted to the surgical substitution of a deteriorated biological aortic valve prosthesis with a new Hancock II biological prosthesis. The implantation was not followed by an anticoagulation or antiaggregation therapy. Two months later he was checked at our Institution because he complained symptoms and developed echocardiographic indexes suggestive of an aortic prosthesis obstruction by a clot.

Role of Cardiovascular Ultrasound in the Evaluation of Obese Subjects.

Obesity represents a worldwide increasing health problem. Obesity, through complex and not fully understood pathogenetic mechanisms, induces different structural and functional changes of left heart chambers, right heart chambers, and arteries. Ultrasound techniques are the first choice for a comprehensive assessment of the cardiovascular adaptation to obesity.

Lower extremities peripheral arterial disease among patients admitted to cardiac rehabilitation: the THINKPAD registry.

Background/objectives: Lower extremities peripheral arterial disease (LE-PAD) across the wide range of conditions for Cardiac Rehabilitation (CR) is poorly understood. The "ATHerosclerosis of the lower extremIties as a liNKed comorbidity in Patients Admitted for carDiac rehabilitation" (THINKPAD) registry explored LE-PAD in CR patients in terms of prevalence and interventions delivered.

Methods: Multicenter, consecutive case series of 1506 patients discharged from 16 CR Units in Italy from May 1 to June 30, 2012.

Depression and reduced heart rate variability after cardiac surgery: the mediating role of emotion regulation.

Background: Heart rate variability (HRV), as an index of autonomic nervous system (ANS) functioning, is reduced by depression after cardiac surgery, but the underlying mechanisms of this relationship are poorly understood. Poor emotion regulation as a core symptom of depression has also been associated with altered ANS functioning. The present study aimed to examine whether emotion dysregulation could be a mediator of the depression-reduced HRV relationship observed after cardiac surgery.

[Standards and outcome measures in cardiovascular rehabilitation. Position paper GICR/IACPR].

Despite major improvements in diagnostics and interventional therapies, cardiovascular diseases remain a major health care and socio-economic problem in Italy. Costs and resources required are increasing in close correlation to both the improved quality of care and to the population ageing. There is an overwhelming evidence of the efficacy of cardiac rehabilitation (CR) in terms of reduction in morbidity and mortality after acute cardiac events.

[Atherosclerosis of the lower extremities as a linked comorbidity in Patients Admitted for cardiac rehabilitation (THINKPAD): rationale, design, and study group].

Peripheral arterial disease (PAD) is a frequent comorbidity among patients entering cardiac rehabilitation (CR) programmes and an important source of disability and impaired prognosis. The prevalence of PAD across the wide range of conditions for CR is poorly understood, as far as its impact on drug optimization and intervention delivered. The "ATHerosclerosis of the lower extremities as a liNKed comorbidity in Patients Admitted for carDiac rehabilitation" (THINKPAD) study was carried out by the Italian Association for Cardiovascular Prevention, Rehabilitation and Epidemiology (GICR-IACPR) in order to explore PAD both as a comorbidity and a primary indication at the entry of CR.

Clinical features and short term outcomes of patients with acute pulmonary embolism. The Italian Pulmonary Embolism Registry (IPER).

Background: Registries are essential to obtain information on the whole spectrum of patients with pulmonary embolism (PE). The aim of the Italian Pulmonary Embolism Registry (IPER) is to report on demographics, clinical features, management, and outcomes of patients diagnosed with PE in everyday clinical practice.

Methods: Patients with confirmed acute PE were enrolled in a web-based registry, in Cardiology, Emergency or Internal Medicine Departments in 47 hospitals in Italy.

Biofeedback assisted control of respiratory sinus arrhythmia as a biobehavioral intervention for depressive symptoms in patients after cardiac surgery: a preliminary study.

The current study investigated whether biofeedback training aimed at increasing respiratory sinus arrhythmia (RSA), a measure of cardiac vagal modulation, can reduce depressive symptoms in patients after cardiac surgery. This randomized controlled study enrolled 26 patients after first-time cardiac surgery. The patients were randomly assigned to an RSA-biofeedback group (N = 13) or to a treatment as usual group (N = 13).
