[ANMCO/GISE/SICOA Consensus document: Role of coronary computed tomography angiography in chronic coronary syndromes].

Chronic coronary syndromes (CCS) are the most common clinical manifestation of coronary atherosclerosis. Coronary computed tomography angiography (CCTA) is a recent innovation in non-invasive cardiac imaging. It is the only anatomical imaging method that allows direct visualization of the coronary lumen, vessel walls, and atherosclerotic plaques, offering high sensitivity and a strong negative predictive value.

[SICI-GISE/SICOA Consensus document: Clinical follow-up of patients after acute coronary syndrome or percutaneous coronary intervention].

In the last decades, advances in percutaneous coronary intervention (PCI) strategies have significantly reduced the risk of procedural complications and in-hospital mortality of patients with acute coronary syndromes (ACS), thus increasing the population of stable post-ACS patients. This novel epidemiological scenario emphasizes the importance of implementing secondary preventive and follow-up strategies. The follow-up of patients after ACS or elective PCI should be based on common pathways and on the close collaboration between hospital cardiologists and primary care physicians.

Accurate Identification of Mucinous Pancreatic Cystic Lesions Using Small-Volume Analytes.

Introduction: The accurate identification of mucinous pancreatic cystic lesions (PCLs) is paramount for cancer risk stratification. Cyst fluid carcinoembryonic antigen (CEA), the only routinely used test, requires high volumes and has low sensitivity. We aimed to compare the performance of two investigational small-volume biomarkers, glucose and the protease gastricsin, to CEA for PCL classification.

Current Use of Oral Anticoagulation Therapy in Elderly Patients with Atrial Fibrillation: Results from an Italian Multicenter Prospective Study-The ISNEP Study.

Background: Atrial fibrillation (AF) is the most common heart arrhythmia, and its prevalence increases with age. Oral Anticoagulant Therapy (OAT) with non-vitamin K antagonist oral anticoagulants (NOACs) or vitamin K antagonists (VKAs) is essential to avoid thromboembolic events in AF. However, this treatment is associated with a high risk of bleeding and low adherence in elderly patients.

Translation of a Protease Turnover Assay for Clinical Discrimination of Mucinous Pancreatic Cysts.

The classification of pancreatic cyst fluids can provide a basis for the early detection of pancreatic cancer while eliminating unnecessary procedures. A candidate biomarker, gastricsin (pepsin C), was found to be present in potentially malignant mucinous pancreatic cyst fluids. A gastricsin activity assay using a magnetic bead-based platform has been developed using immobilized peptide substrates selective for gastricsin bearing a dimeric rhodamine dye.

[HCF-ANMCO/AICPR/GIEC/ITAHFA/SICOA/SICP/SIMG/SIT Cardiological Societies Council Consensus document: Anticoagulant therapy in venous thromboembolism and atrial fibrillation of the patient with cancer. Current knowledge and new evidence].

Venous thromboembolism (VTE), including pulmonary embolism and deep venous thrombosis, either symptomatic or incidental, is a common complication in the history of cancer disease. The risk of VTE is 4-7-fold higher in oncology patients, and it represents the second leading cause of death, after cancer itself. In cancer patients, compared with the general population, VTE therapy is associated with higher rates of recurrent thrombosis and/or major bleeding.

KH-Type Splicing Regulatory Protein Controls Colorectal Cancer Cell Growth and Modulates the Tumor Microenvironment.

KH-type splicing regulatory protein (KHSRP) is a multifunctional nucleic acid binding protein implicated in key aspects of cancer cell biology: inflammation and cell-fate determination. However, the role KHSRP plays in colorectal cancer (CRC) tumorigenesis remains largely unknown. Using a combination of in silico analysis of large data sets, ex vivo analysis of protein expression in patients, and mechanistic studies using in vitro models of CRC, we investigated the oncogenic role of KHSRP.

The lysosomal aminopeptidase tripeptidyl peptidase 1 displays increased activity in malignant pancreatic cysts.

Incidental detection of pancreatic cysts has increased dramatically over the last decade, but risk stratification and clinical management remain a challenge. Mucinous cysts are precursor lesions to pancreatic cancer, however, the majority are indolent. Current diagnostics cannot identify mucinous cysts that harbor cancer or reliably differentiate these lesions from nonmucinous cysts, which present minimal risk of malignant progression.

Depleted polymorphonuclear leukocytes in human metastatic liver reflect an altered immune microenvironment associated with recurrent metastasis.

Background: Hepatic immunity, normally protective against neoplasia, is subverted in colorectal liver metastasis (CRLM). Here, we compare the inflammatory microenvironment of CRLM-bearing liver tissue to donor liver.

Methods: Twenty-five patients undergoing resection for CRLM were recruited, 13 of whom developed intrahepatic recurrence within 18 months.

Immunoproteasome functions explained by divergence in cleavage specificity and regulation.

The immunoproteasome (iP) has been proposed to perform specialized roles in MHC class I antigen presentation, cytokine modulation, and T cell differentiation and has emerged as a promising therapeutic target for autoimmune disorders and cancer. However, divergence in function between the iP and the constitutive proteasome (cP) has been unclear. A global peptide library-based screening strategy revealed that the proteasomes have overlapping but distinct substrate specificities.

[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.

Methods: The study was carried out using a web-based questionnaire running on the GICR-IACPR website for 4 weeks from September 2 to 29, 2013.

Preclinical evaluation of the AR inhibitor enzalutamide in triple-negative breast cancer cells.

The androgen receptor (AR) is present in approximately 80% of invasive breast cancer patients and in up to 30% of patients with triple-negative breast cancer (TNBC). Therefore, our aim was to investigate the targeting of AR as a possible hormonal approach to the treatment of TNBC. Analysis of 2091 patients revealed an association between AR expression and poor overall survival, selectively in patients with the basal subtype of breast cancer, the vast majority of which are TNBC.

Incidence and clinical presentation of myocardial ischemia in patients with chronic CAD in Italy: the ISPICA survey study.

Aim: This survey study was performed to provide an overall picture on the incidence of symptoms, with or without typical angina, in the real-life clinical practice and to identify clinical factors associated with atypical presentations in an unselected population of consecutive outpatients with chronic coronary artery disease (CAD).

Methods: Thirty-six cardiology units located in different geographic areas of Italy enrolled a total of 1475 outpatients (73.6% men and 26.

Targeting EGFR in metastatic colorectal cancer beyond the limitations of KRAS status: alternative biomarkers and therapeutic strategies.

Patients with metastatic colorectal cancer have a very poor prognosis. Incorporation of targeted molecular therapies, such as the anti-EGFR receptor monoclonal antibodies cetuximab and panitumumab, into treatment regimens has improved outcomes for patients with wild-type RAS tumors. Yet, response rates remain low and overall survival times are short.

Estrogen receptors and their implications in colorectal carcinogenesis.

Upon binding their cognate receptors, ERα (ESR1) and ERβ (ESR2), estrogens activate intracellular signaling cascades that have important consequences for cellular behavior. Historically linked to carcinogenesis in reproductive organs, estrogens have also been implicated in the pathogenesis of different cancer types of non-reproductive tissues including the colon. ERβ is the predominant estrogen receptor expressed in both normal and malignant colonic epithelium.

Oocyte maturation: a story of arrest and release.

The release of a mature healthy egg for fertilization is the center of the entire reproductive process. From the time of embryonic development till fertilization, the oocyte undergoes several stop-and-go periods. In most animals, oocytes are held in meiotic arrest in prophase I prior to ovulation.

Cytosolic phospholipase A2 activation correlates with HER2 overexpression and mediates estrogen-dependent breast cancer cell growth.

Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) catalyzes the hydrolysis of membrane glycerol-phospholipids to release arachidonic acid as the first step of the eicosanoid signaling pathway. This pathway contributes to proliferation in breast cancer, and numerous studies have demonstrated a crucial role of cyclooxygenase 2 and prostaglandin E(2) release in breast cancer progression. The role of cPLA(2)alpha activation is less clear, and we recently showed that 17beta-estradiol (E2) can rapidly activate cPLA(2)alpha in MCF-7 breast cancer cells.

Estrogen, phospholipase A and breast cancer.

The development of breast cancer is promoted by diverse factors that impact on intracellular signaling to promote proliferation and cell survival. The role of eicosanoid signaling through prostaglandin release and the up-regulation of cyclooxygenase-2 (COX-2) is established, however, the impact of phospholipase A (PLA) activity and over-expression is less certain. Here we review current literature concerning the role of PLA in breast cancer and describe how eicosanoid signaling may be a facet of estrogen-stimulated breast cancer etiology and progression.

17Beta-estradiol induces ERbeta up-regulation via p38/MAPK activation in colon cancer cells.

Estrogen receptors (ERalpha and ERbeta) mediate opposite functions on cancer growth induced by 17beta-estradiol (E2). E2 binding to ERalpha induces a cancer promoting response, whereas E2 binding to ERbeta exerts a protective action against cancer growth. Moreover, E2 can diversely modulate the ERalpha and ERbeta levels intensifying or decreasing their actions in target tissues.

Role of ERbeta palmitoylation in the inhibition of human colon cancer cell proliferation.

The cellular functions regulated by 17beta-estradiol (E2) start after the hormone binds to its receptors (i.e., ERalpha and ERbeta).
