Effect of age and treatment on predictive value of measurable residual disease: implications for clinical management of adult patients with acute myeloid leukemia.

Measurable residual disease (MRD) is a powerful predictor of outcome in acute myeloid leukemia. In the early phases of treatment, MRD refines initial disease risk stratification and is used for the allocation to allogeneic transplant. Despite its well-established role, a relatively high fraction of patients eventually relapses albeit achieving MRDneg status. The aim of this work was to assess specifically the influence of baseline features and treatment intensity on the predictive value of an MRDneg status, particularly focusing on MRD2, measured after two consecutive chemotherapy cycles. Among baseline features, younger MRD2neg patients (<55 years) had a significantly longer disease-free survival (median not reached) compared to their older counterparts (median 25.0 months, P=0.013, hazard ratio=2.08). Treatment intensity, specifically the delivery of a high dose of cytarabine in induction or first consolidation, apparently had a pejorative effect on the outcome of MRD2neg patients compared to standard dose (P=0.048, hazard ratio=1.80), a finding also confirmed by the analysis of data extracted from the literature. The combination of age and treatment intensity allowed us to identify categories of patients, among those who reached a MRD2neg status, characterized by significantly different disease-free survival rate. Our data showed that variables such as age and intensity of treatment administered can influence the predictive value of MRD in patients with acute myeloid leukemia. In addition to underscoring the need for further improvement of MRD analysis, these findings call for a reasoned application of MRD data, as currently available, to modulate consolidation therapy on adequately estimated relapse rates.

[ANMCO Position paper: Ionizing radiation exposure and radioprotection in the cath-lab]. / Position paper ANMCO: Radioesposizione e radioprotezione nei laboratori di cardiologia interventistica.

In the last decades, because of the improvements in the percutaneous treatment of coronary heart disease, valvular heart disease, congenital heart defects, and the increasing number of cardiac resynchronization therapy and cardioverter-defibrillator implantations, the interventional cardiologists' radio-exposure has importantly risen, causing concerns for ionizing radiation-associated diseases such as cancer and neurodegenerative disorders. Consequently, the radiation exposure issue importantly affects operators' safety. However, our knowledge of this field is poor and most operators are unaware to be at risk, especially because of the absence of effective preventive measures. The aim of this ANMCO position paper is to improve the awareness of operators and identify new ways of reducing operator ionizing radiation dose and minimizing the risk.

Care of patients with ST-elevation myocardial infarction: an international analysis of quality indicators in the acute coronary syndrome STEMI Registry of the EURObservational Research Programme and ACVC and EAPCI Associations of the European Society of Cardiology in 11 462 patients.

AIMS: To use quality indicators to study the management of ST-segment elevation myocardial infarction (STEMI) in different regions. METHODS AND RESULTS: Prospective cohort study of STEMI within 24 h of symptom onset (11 462 patients, 196 centres, 26 European Society of Cardiology members, and 3 affiliated countries). The median delay between arrival at a percutaneous cardiovascular intervention (PCI) centre and primary PCI was 40 min (interquartile range 20-74) with 65.8% receiving PCI within guideline recommendation of 60 min. A third of patients (33.2%) required transfer from their initial hospital to one that could perform emergency PCI for whom only 27.2% were treated within the quality indicator recommendation of 120 min. Radial access was used in 56.6% of all primary PCI, but with large geographic variation, from 76.4 to 9.1%. Statins were prescribed at discharge to 98.7% of patients, with little geographic variation. Of patients with a history of heart failure or a documented left ventricular ejection fraction ≤40%, 84.0% were discharged on an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker and 88.7% were discharged on beta-blockers. CONCLUSION: Care for STEMI shows wide geographic variation in the receipt of timely primary PCI, and is in contrast with the more uniform delivery of guideline-recommended pharmacotherapies at time of hospital discharge.

Rapid evaluation of T cell clonality in the diagnostic work-up of mature T cell neoplasms: TRBC1-based flow cytometric assay experience.

The identification of mature T cell neoplasms by flow cytometry is often challenging, due to overlapping features with reactive T cells and limitations of currently available T cell clonality assays. The description of an antibody specific for one of two mutually exclusive T cell receptor (TCR) ß-chain constant regions (TRBC1) provides an opportunity to facilitate the detection of clonal TCRαß+ T cells based on TRBC-restriction. Here we prospectively analyzed 14 healthy controls and 63 patients with the flow cytometry protocol currently used for suspected T cell neoplasm implemented with immunostaining targeting TRBC1. Specimens were firstly classified in 3 groups based on clinical records data, laboratory findings and immunophenotypic features. T cell clonality was assessed by TCR Vß repertoire analysis and the new rapid TRBC1 assay. Results showed that TRBC1 unimodal expression was unequivocally associated with samples presenting with immunophenotypic aberrancies. Moreover, we demonstrated that the use of TRBC1 is useful in solving uncertain cases and confirmed the high sensitivity of the method in identifying small T cell clones of uncertain significance (T-CUS). Finally, we found a high degree of concordance (97%) comparing the currently available clonality assessment methods with the proposed new method. In conclusion, our results provided real-life evidence of the utility of TRBC1 introduction in the flow cytometric clonality evaluation for the routine diagnostic work-up of T cell neoplasms.

Clinical and Immunological Features of SARS-CoV-2 Breakthrough Infections in Vaccinated Individuals Requiring Hospitalization.

BACKGROUND AND PURPOSE: Waning immunity and the surge of SARS-CoV-2 variants are responsible for breakthrough infections, i.e., infections in fully vaccinated individuals. Although the majority of vaccinated infected subjects report mild or no symptoms, some others require hospitalization. The clinical and immunological features of vaccinated hospitalized COVID-19 patients are currently unknown. METHODS: Twenty-nine unvaccinated and 36 vaccinated hospitalized COVID-19 patients were prospectively enrolled and clinical and laboratory data were gathered. Immunophenotyping of leukocytes' subsets, T and B cell SARS-CoV-2-specific responses were evaluated via flow cytometry. Anti-IFN-α autoantibodies were measured via ELISA. RESULTS: Despite vaccinated patients were older and with more comorbidities, unvaccinated subjects showed higher levels of pro-inflammatory markers, more severe disease, and increased mortality rate. Accordingly, they presented significant alterations in the circulating leukocyte composition, typical of severe COVID-19. Vaccinated patients displayed higher levels of anti-Spike IgGs and Spike-specific B cells. Of all participants, survivors showed higher levels of anti-Spike IgGs and Spike-specific CD4+ T cells than non-survivors. At hospital admission, 6 out of 65 patients (9.2%) displayed high serum concentrations of autoantibodies targeting IFN-α. Remarkably, 3 were unvaccinated and eventually died, while the other 3 were vaccinated and survived. CONCLUSION: Despite more severe pre-existing clinical conditions, vaccinated patients have good outcome. A rapid activation of anti-SARS-CoV-2-specific immunity is fundamental for the resolution of the infection. Therefore, prior immunization through vaccination provides a significant contribution to prevention of disease worsening and can even overcome the presence of high-risk factors (i.e., older age, comorbidities, anti-IFN-α autoantibodies).

Integration of multiparameter flow cytometry score improves prognostic stratification provided by standard models in primary myelofibrosis.

Prognostic modeling in myelofibrosis (MF) has classically pursued the integration of informative clinical and hematological parameters to separate patients' categories with different outcomes. Modern stratification includes also genetic data from karyotype and mutations. However, some poorly standardized variables, as peripheral blood (PB) blast count by morphology, are still included. In this study, we used multiparameter flow cytometry (MFC) with the aim of improving performance of existing scores. We studied 363 MF patients with available MFC files for PB CD34+ cells count determination at diagnosis. We adapted Ogata score to MF context including 2 parameters: absolute CD34+ cells count (/µL) and granulocytes to lymphocytes SSC ratio. A score of 1 was attributed to above-threshold values of each parameter. Accordingly, patients were categorized as MFClow (score = 0, 62.0%), MFCint (score = 1, 29.5%), and MFChigh (score = 2, 8.5%). MFClow had significantly longer median OS (not reached) compared to MFCint (55 months) and MFChigh (19 months). We integrated MFC into established models as a substitute of morphological PB blasts count. Patients were reclassified according to MFC-enhanced scores, and concordance (C-) indexes were compared. As regards IPSS, C-indexes were 0.67 and 0.74 for standard and MFC-enhanced model, respectively (Z score - 3.82; p = 0.0001). MFC-enhanced MIPSS70+ model in PMF patients yielded a C-index of 0.78, outperforming its standard counterpart (C-index 0.73; Z score - 2.88, p = 0.004). Our data suggest that the incorporation of MFC-derived parameters, easily attainable from standard assay used for CD34+ cells determination, might help to refine the current prognostic stratification models in myelofibrosis.

Reperfusion therapies and in-hospital outcomes for ST-elevation myocardial infarction in Europe: the ACVC-EAPCI EORP STEMI Registry of the European Society of Cardiology.

AIMS: The aim of this study was to determine the contemporary use of reperfusion therapy in the European Society of Cardiology (ESC) member and affiliated countries and adherence to ESC clinical practice guidelines in patients with ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: Prospective cohort (EURObservational Research Programme STEMI Registry) of hospitalized STEMI patients with symptom onset <24 h in 196 centres across 29 countries. A total of 11 462 patients were enrolled, for whom primary percutaneous coronary intervention (PCI) (total cohort frequency: 72.2%, country frequency range 0-100%), fibrinolysis (18.8%; 0-100%), and no reperfusion therapy (9.0%; 0-75%) were performed. Corresponding in-hospital mortality rates from any cause were 3.1%, 4.4%, and 14.1% and overall mortality was 4.4% (country range 2.5-5.9%). Achievement of quality indicators for reperfusion was reported for 92.7% (region range 84.8-97.5%) for the performance of reperfusion therapy of all patients with STEMI <12 h and 54.4% (region range 37.1-70.1%) for timely reperfusion. CONCLUSIONS: The use of reperfusion therapy for STEMI in the ESC member and affiliated countries was high. Primary PCI was the most frequently used treatment and associated total in-hospital mortality was below 5%. However, there was geographic variation in the use of primary PCI, which was associated with differences in in-hospital mortality.

AMELIORATE: early intensification in FLT3-mutated acute myeloid leukemia based on peripheral blast clearance - MYNERVA-GIMEMA AML1919 trial.

AMELIORATE is a Phase III, randomized trial aiming to personalize treatment intensity in FLT3-mutated acute myeloid leukemia. The current study provides an early appraisal of chemosensitivity based on peripheral blasts clearance, as assessed by multiparameter flow cytometry, from baseline to day 4 of induction. This biomarker was previously demonstrated to predict complete remission achievement and measurable residual disease status. For patients experiencing low peripheral blast cells (i.e., ≤2.0 logs), two major adjustments of treatment as compared with current standard of care are envisioned in the experimental arm: the immediate switch to intensified induction with high-doses cytarabine (1500 mg/m2 b.i.d. on days 5-7 of induction); and the early allocation of the patient to high-risk disease category, to be further refined later based on postinduction measurable residual disease status.

Lay abstract The initial treatment of acute myeloid leukemia is called induction and aims to reduce significantly the number of leukemic cells in the bone marrow. In young adults, this phase comprises several agents, including conventional chemotherapy, monoclonal antibodies, and targeted drugs. Conventionally, induction is delivered as a single block of therapy, the response to which can be appreciated 3­4 weeks after its completion. The authors previously showed that the response to induction can be anticipated by the speed of disappearance of leukemic cells from peripheral blood after four days of therapy. In the AMELIORATE study, the authors aim to personalize the intensity of treatment based on this biomarker, by early intensification of treatment in patients who are predicted to have a poor response.

Venetoclax-Based Regimens for Relapsed/Refractory Acute Myeloid Leukemia in a Real-Life Setting: A Retrospective Single-Center Experience.

Relapsed/refractory (R/R) acute myeloid leukemia (AML) is a largely unmet medical need, owing to the lack of standardized, effective treatment approaches, resulting in an overall dismal outcome. The only curative option for R/R AML patients is allogeneic hematopoietic stem cell transplantation (HSCT) which is only applicable in a fraction of patients due to the scarce efficacy and high toxicity of salvage regimens. Recently, a number of targeted agents with relatively favorable toxicity profiles have been explored in clinical trials for R/R AML patients. The Bcl-2 inhibitor venetoclax, in combination with hypomethylating agents or low dose cytarabine, has produced impressive results for newly diagnosed AML, while its role in R/R disease is not well defined yet. We retrospectively analyzed the clinical outcomes of 47 R/R AML patients treated with venetoclax-based regimens between March 2018 and December 2020 at our institution. Overall, we report a composite complete response rate of 55% with an overall acceptable toxicity profile. Outcomes were particularly favorable for NPM1 mutated patients, unlike for FLT3-ITD positive patients irrespective of NPM1 status. For patients treated with intention to transplant, the procedure could be finally performed in 54%. These findings suggest a role for venetoclax-based regimens in R/R AML patients and support the design of prospective studies.

TCR Vß Evaluation by Flow Cytometry.

T-cell receptor (TCR)-Vß repertoire analysis is a sensitive method for detection of T-cell clonality. This type of analysis has been used for studying selective T-cell responses in autoimmune disease, alloreactivity in transplantation, and protective immunity against microbial and tumor antigens and in neoplastic T cells. Here, we describe the flow cytometric methods to perform this analysis.

Multilineage Dysplasia as Assessed by Immunophenotype in Acute Myeloid Leukemia: A Prognostic Tool in a Genetically Undefined Category.

Acute myeloid leukemia (AML) "with myelodysplasia-related changes (MRC)" is considered a separate entity by the World Health Organization (WHO) classification of myeloid neoplasms. While anamnestic and cytogenetic criteria provide objective attribution to this subset, with clear unfavorable prognostic significance, the actual role of multi-lineage dysplasia (MLD) as assessed by morphology is debated. The aim of our work was to study MLD by a technique alternative to morphology, which is multiparameter flow cytometry (MFC), in a large series of 302 AML patients intensively treated at our Center. The correlation with morphology we observed in the unselected analysis reiterated the capability of the MFC-based approach at highlighting dysplasia. MLD data, estimated through an immune-phenotypic score (IPS), provided no insight into prognosis when considered overall nor within well-defined genetic categories. Of interest, IPS-related dysplasia conveyed significant prognostic information when we focused on genetically undefined patients, triple-negative for NPM1, FLT3 and CEBPA (TN-AML). In this context, the lack of dysplastic features (IPS_0) correlated with a significantly higher CR rate and longer survival compared to patients showing dysplasia in one or both (neutrophil and erythroid) cell lineages. The impact of IPS category maintained its validity after censoring at allogeneic HSCT and in a multivariate analysis including baseline and treatment-related covariates. In a subgroup featured by the lack of genetic determinants, our data could help address the relative unmet needs in terms of risk assessment and treatment strategy, and provide insight into prediction of response in the rapidly evolving therapeutic scenario of AML.

Downstream or upstream administration of P2Y12 receptor blockers in non-ST elevated acute coronary syndromes: study protocol for a randomized controlled trial.

BACKGROUND: The optimal timing to administer a P2Y12 inhibitor in patients presenting with a non-ST elevation acute coronary syndrome remains a topic of debate. Pretreatment with ticagrelor before coronary anatomy is known as a widely adopted strategy. However, there is poor evidence on how this compares with administration of a P2Y12 inhibitor after defining coronary anatomy (i.e., downstream administration). Moreover, there are limited head-to-head comparisons of the two P2Y12 inhibitors-ticagrelor and prasugrel-currently recommended by the guidelines. STUDY DESIGN: DUBIUS is a phase 4, multicenter, parallel-group, double randomized study conducted in NSTE-ACS patients designed to compare a pretreatment strategy (including only ticagrelor) versus a downstream strategy (including prasugrel or ticagrelor) and to compare downstream prasugrel with downstream ticagrelor. A total of 2520 patients will be randomly assigned to pretreatment with ticagrelor or to no pretreatment. The PCI group of the downstream arm will be further randomized to receive prasugrel or ticagrelor. The two primary hypotheses are that the downstream strategy is superior to the upstream strategy and that downstream ticagrelor is non-inferior to downstream prasugrel, both measured by the incidence of a composite efficacy and safety endpoint of death from vascular causes, non-fatal MI, or non-fatal stroke, and Bleeding Academic Research Consortium (BARC) type 3, 4, and 5 bleedings. CONCLUSIONS: The DUBIUS study will provide important evidence related to the benefits and risks of pretreatment with ticagrelor compared with a strategy of no pretreatment. Moreover, the clinical impact of using downstream ticagrelor compared with downstream prasugrel will be assessed. TRIAL REGISTRATION: ClinicalTrials.gov NCT02618837 . Registered on 1 December 2015.

Insulin resistance and obesity affect monocyte-derived dendritic cell phenotype and function.

AIM: Cardiovascular disease (CVD) is prevalent in women after menopause, which may be associated with obesity, insulin resistance and metaflammation. Despite the recognized role of immunological mechanisms in vascular remodeling, the role of dendritic cells (DCs) is still unclear. The aim was to characterize monocyte-derived DCs (Mo-DC) in post-menopausal patients with type 2 diabetes (T2DM) and obese woman, without clinical manifestations of atherosclerosis. METHODS: Obese post-menopausal women with or without T2DM were enrolled and were compared to age-matched healthy women. DCs obtained from patients were phenotypically and functionally characterized by flow cytometry and mixed lymphocyte reaction. MRNA integrins expression was assessed by real time RT-PCR; circulating fetuin-A and adiponectin levels were measured by ELISA. RESULTS: Phenotypic dysregulation of Mo-DC reported was related to a defective allogenic lymphocyte stimulation and to an increased mRNA of CD11c, CD18 and DC-SIGN/CD209 which regulate their adhesion to vascular wall cells. Fetuin-A and adiponectin levels were significantly altered and negatively correlated. Hyperglycaemia significantly impaired CD14+ transdifferentiation into Mo-DC. CONCLUSIONS: These data show a dysfunction of Mo-DCs obtained from precursors isolated from T2DM obese post-menopausal woman without any documented clinical CV event. Association of obesity to diabetes seems to worsen DC's phenotype and function and increase vascular inflammation.

Timing of Oral P2Y12 Inhibitor Administration in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome.

BACKGROUND: Although oral P2Y12 inhibitors are key in the management of patients with non-ST-segment elevation acute coronary syndrome, the optimal timing of their administration is not well defined. OBJECTIVES: The purpose of this study was to compare downstream and upstream oral P2Y12 inhibitors administration strategies in patients with non-ST-segment elevation acute coronary syndrome undergoing invasive treatment. METHODS: We performed a randomized, adaptive, open-label, multicenter clinical trial. Patients were randomly assigned to receive pre-treatment with ticagrelor before angiography (upstream group) or no pre-treatment (downstream group). Patients in the downstream group undergoing percutaneous coronary intervention were further randomized to receive ticagrelor or prasugrel. The primary hypothesis was the superiority of the downstream versus the upstream strategy on the combination of efficacy and safety events (net clinical benefit). RESULTS: We randomized 1,449 patients to downstream or upstream oral P2Y12 inhibitor administration. A pre-specified stopping rule for futility at interim analysis led the trial to be stopped. The rate of the primary endpoint, a composite of death due to vascular causes; nonfatal myocardial infarction or nonfatal stroke; and Bleeding Academic Research Consortium type 3, 4, and 5 bleeding through day 30, did not differ significantly between the downstream and upstream groups (percent absolute risk reduction: -0.46; 95% repeated confidence interval: -2.90 to 1.90). These results were confirmed among patients undergoing percutaneous coronary intervention (72% of population) and regardless of the timing of coronary angiography (within or after 24 h from enrollment). CONCLUSIONS: Downstream and upstream oral P2Y12 inhibitor administration strategies were associated with low incidence of ischemic and bleeding events and minimal numeric difference of event rates between treatment groups. These findings led to premature interruption of the trial and suggest the unlikelihood of enhanced efficacy of 1 strategy over the other. (Downstream Versus Upstream Strategy for the Administration of P2Y12 Receptor Blockers In Non-ST Elevated Acute Coronary Syndromes With Initial Invasive Indication [DUBIUS]; NCT02618837).

Quantitative and qualitative alterations of circulating myeloid cells and plasmacytoid DC in SARS-CoV-2 infection.

SARS-CoV-2 is responsible for a new infectious disease (COVID-19) in which individuals can either remain asymptomatic or progress from mild to severe clinical conditions including acute respiratory distress syndrome and multiple organ failure. The immune mechanisms that potentially orchestrate the pathology in SARS-CoV-2 infection are complex and only partially understood. There is still paucity of data on the features of myeloid cells involved in this viral infection. For this reason, we investigated the different activation status profiles and the subset distribution of myeloid cells and their correlation with disease progression in 40 COVID-19 patients at different stages of disease. COVID-19 patients showed a decrease in the absolute number of plasmacytoid and myeloid dendritic cells, different subset distribution of monocytes and different activation patterns of both monocytes and neutrophils, coupled to a significant reduction of HLA-DR monocyte levels. We found that some of these alterations are typical of all COVID-19 patients, while some others vary at different stages of the disease and correlate with biochemical parameters of inflammation. Collectively, these data suggest that not only the lymphoid, but also the myeloid compartment, is severely affected by SARS-CoV-2 infection.

In Vitro Comparison of the Effects of Imatinib and Ponatinib on Chronic Myeloid Leukemia Progenitor/Stem Cell Features.

BACKGROUND: The development of molecularly tailored therapeutic agents such as the BCR/ABL-active tyrosine kinase inhibitors (TKi) resulted in an excellent treatment option for chronic myeloid leukemia (CML) patients. However, following TKi discontinuation, disease relapses in 40-60% of patients, an occurrence very likely due to the persistence of leukemic stem cells that are scarcely sensitive to TKi. Nevertheless, TKi are still the only current treatment option for CML patients. OBJECTIVE: The aim of this study was to compare the effects of TKi belonging to different generations, imatinib and ponatinib (first and third generation, respectively), on progenitor/stem cell expansion potential and markers. PATIENTS AND METHODS: We used stabilized CML cell lines (KCL22, K562 and LAMA-84 cells), taking advantage of the previous demonstration of ours that cell lines contain cell subsets endowed with progenitor/stem cell properties. Primary cells explanted from CML patients were also used. The effects of TKi on the expression of stem cell related genes were compared by quantitative PCR. Flow cytometry was performed to evaluate aldehyde-dehydrogenase (ALDH) activity and the expression of cluster of differentiation (CD) cell surface hematopoietic stem cell markers. Progenitor/stem cell potential was estimated by serial colony formation ability (CFA) assay. RESULTS: Ponatinib was more effective than imatinib for the reduction of cells with ALDH activity and progenitor/stem cell potential of CML patient-derived cells and cell lines. Furthermore, ponatinib was more effective than imatinib in reducing the percentage of CD26-expressing cells in primary CML cells, whereas imatinib and ponatinib showed similar efficacy on KCL22 cells. Both drugs strongly upregulated NANOG and SOX2 in CML cell lines, but in KCL22 cells this upregulation was significantly lower with ponatinib than with imatinib, an outcome compatible with a lower level of enrichment of the stem cell compartment upon ponatinib treatment. CONCLUSION: Ponatinib seems to target CML progenitor/stem cells better than imatinib.

Impaired immune cell cytotoxicity in severe COVID-19 is IL-6 dependent.

BACKGROUNDCoronavirus disease 19 (COVID-19) is an emerging infectious disease caused by SARS-CoV-2. Antiviral immune response is crucial to achieve pathogen clearance; however, in some patients an excessive and aberrant host immune response can lead to an acute respiratory distress syndrome. The comprehension of the mechanisms that regulate pathogen elimination, immunity, and pathology is essential to better characterize disease progression and widen the spectrum of therapeutic options.METHODSWe performed a flow cytometric characterization of immune cell subsets from 30 patients with COVID-19 and correlated these data with clinical outcomes.RESULTSPatients with COVID-19 showed decreased numbers of circulating T, B, and NK cells and exhibited a skewing of CD8+ T cells toward a terminally differentiated/senescent phenotype. In agreement, CD4+ T and CD8+ T, but also NK cells, displayed reduced antiviral cytokine production capability. Moreover, a reduced cytotoxic potential was identified in patients with COVID-19, particularly in those who required intensive care. The latter group of patients also showed increased serum IL-6 levels that inversely correlated to the frequency of granzyme A-expressing NK cells. Off-label treatment with tocilizumab restored the cytotoxic potential of NK cells.CONCLUSIONThe association between IL-6 serum levels and the impairment of cytotoxic activity suggests the possibility that targeting this cytokine may restore antiviral mechanisms.FUNDINGThis study was supported by funds from the Department of Experimental and Clinical Medicine of University of Florence (the ex-60% fund and the "Excellence Departments 2018-2022 Project") derived from Ministero dell'Istruzione, dell'Università e della Ricerca (Italy).

[ANMCO/SIC/GISE/ARCA/SIRM Consensus document: Description of coronary atherosclerosis for diagnostic, prognostic and therapeutic purposes]. / Documento di consenso intersocietario ANMCO/SIC/GISE/ARCA/SIRM: Descrizione dell'aterosclerosi coronarica ai fini diagnostici, prognostici e terapeutici.

Both conventional coronary angiography and cardiac computed tomography have greatly improved our diagnostic and prognostic evaluation of patients with either suspected or confirmed coronary artery disease. Although several other tools can provide information about coronary anatomy or function, invasive coronary angiography and, more recently, coronary computed tomography angiography (CCTA) are the most commonly used imaging modalities. Coronary atherosclerosis is the most common disease of the coronary arteries and its presence identifies patients at increased risk of events. As a matter of fact, coronary atherosclerosis represents the major determinant for the occurrence of events and the development of ischemic heart disease. Coronary atherosclerosis can translate into plaques that may eventually progress to critical stenosis causing myocardial ischemia. More commonly, atherosclerotic lesions are non-obstructive. Their presence, number and extent negatively affect prognosis independently of other mechanisms. In order to improve prognosis, optimal medical therapy should be initiated to halt disease progression and/or to stabilize atherosclerotic plaques. It is therefore of paramount importance to describe the presence of atherosclerotic lesions well beyond those lesions potentially or undoubtedly capable of inducing myocardial ischemia. These latter lesions may in fact benefit from an interventional or surgical treatment. However, most events are caused by non-obstructive lesions that may often be missed.In common practice, the description of coronary anatomy is not structured in a universal model and each Center applies its own (albeit arbitrary) rules. This consensus document is a collaborative work of some of the major Italian Scientific Societies to offer scientific support to those healthcare professionals who, at different levels, report on coronary anatomy or receive the description of coronary anatomy of patients. After a brief description of the available techniques used to explore the coronary anatomy, the best available evidence in support of a detailed description of coronary atherosclerosis is summarized. In order to promote a useful translation of the information into practice, several recommendations for the correct reporting of coronary anatomy and the suggested treatment for the different clinical scenarios are provided. The aim of this consensus document is to refine the description of coronary anatomy as offered by both invasive coronary angiography and CCTA to improve risk stratification of patients undergoing coronary imaging in clinical practice and to select the most appropriate treatment for improving cardiovascular outcomes.

[ANMCO/FADOI/SIAARTI/SIC/SIMG/SIMI/SIMEU consensus document: The clinical care pathway of acute heart failure patients from symptom onset to discharge from the emergency department]. / Documento di consenso ANMCO/FADOI/SIAARTI/SIC/SIMG/SIMI/SIMEU: Il percorso clinico-diagnostico e terapeutico del paziente con scompenso cardiaco acuto dal domicilio alla dimissione dal Pronto Soccorso/ Dipartimento di Emergenza-Accettazione.

Acute heart failure (AHF) represents a relevant burden for emergency departments worldwide. AHF patients have markedly worse long-term outcomes than patients with other acute cardiac diseases (e.g. acute coronary syndromes); mortality or readmissions rates at 3 months approximate 33%, whereas 1-year mortality from index discharge ranges from 25% to 50%.The multiplicity of healthcare professionals acting across the care pathway of AHF patients represents a critical factor, which generates the need for integrating the different expertise and competence of general practitioners, emergency physicians, cardiologists, internists, and intensive care physicians to focus on care goals able to improve clinical outcomes.This consensus document results from the cooperation of the scientific societies representing the different healthcare professionals involved in the care of AHF patients and describes shared strategies and pathways aimed at ensuring both high quality care and better outcomes. The document describes the patient journey from symptom onset to the clinical suspicion of AHF and home management or referral to emergency care and transportation to the hospital, through the clinical diagnostic pathway in the emergency department, acute treatment, risk stratification and discharge from the emergency department to ordinary wards or home. The document analyzes the potential role of a cardiology fast-track and Observation Units and the transition to outpatient care by general practitioners and specialist heart failure clinics.The increasing care burden and complex problems generated by AHF are unlikely to be solved without an integrated multidisciplinary approach. Efficient networking among emergency departments, intensive care units, ordinary wards and primary care settings is crucial to achieve better outcomes. Thanks to the joint effort of qualified scientific societies, this document aims to achieve this goal through an integrated, shared and applicable pathway that will contribute to a homogeneous care management of AHF patients across the country.
