332 Clinical and prognostic significance of junctional late gadolinium enhancement in patients with non-ischaemic cardiomyopathy
Abstract
Aims
Pulmonary hypertension (PH) carries a poor prognosis in patients with non-ischaemic dilated cardiomyopathy (NIDC). Cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) evaluation can identify myocardial abnormalities. In particular, junctional LGE is already an established marker of adverse right ventricular (RV) remodelling in patients with pre-capillary PH. This study sought to assess the prevalence of junctional LGE by CMR in NIDC, its relationship with hemodynamic parameters and, moreover, its prognostic significance.
Methods and results
Patients with NIDC who underwent right heart catheterization (RHC) and CMR within 3 months in a tertiary hospital were enrolled. Patients with acute heart failure were excluded. Among others, RV and left ventricular (LV) volumes, junctional LGE at CMR, pulmonary artery pressure (PAP) and pulmonary capillary wedge pressure (PCWP) at RHC were tabulated. Pulmonary hypertension was defined accordingly to current Guidelines (median PAP at RHC ≥ 25 mmHg). The primary endpoint consisted of heart failure (HF) hospitalization during follow-up. A total of 188 patients [median age 49 (SD 15), 71% males] were evaluated. At morpho-functional CMR evaluation, most subjects (76%) had important systolic dysfunction (LV EF ≤ 35%). Junctional LGE was observed in 83 (44%) patients. Among patients with junctional LGE, 21 had LGE confined only to the junctional region, while 61 had also mid-wall interventricular septal stria and 21 a mid-wall stria in the lateral free LV wall. Patients with junctional LGE had lower RV EF (49% vs. 56%, P < 0.001) and LV EF (27% vs. 30%, P = 0.012) when compared to those without junctional LGE although no differences in LV and RV dimensions were found. RHC showed PH in 83 patients (44%). Patients with junctional LGE showed a worse hemodynamic profile in terms of PH (55% vs. 36%; P = 0.011) and increase in PCWP (PCWP > 15 mmHg in 60% vs. 42%; P = 0.015) compared to subjects without junctional LGE. Among 79 patients with PH and PCWP > 15 mmHg, 75 (95%) had a combined post capillary and pre-capillary PH (diastolic pressure gradient ≥7 mmHg). Univariate analysis showed that junctional LGE was associated with a worse hemodynamic profile; on multivariable model, RV EF was significantly associated with the presence of junctional LGE (OR: 0.91; 95% CI: 0.87–0.96, P < 0.001). During a median follow-up of 58 months, 33 patients (18%) died or underwent heart transplantation/ventricular assist device implantation, 17% in the junctional LGE group vs. 18% among those without junctional LGE. Thirty-eight patients (20%) had at least one episode of HF, 22 among junctional LGE group and 16 in control group (27% vs. 15%, P = 0.056). When adjusted for age, junctional LGE resulted a significant determinant of HF hospitalization (OR: 2.13, 95% CI: 1.02–4.44, P = 0.044).
Conclusions
Junctional LGE is detectable in almost half of NIDC patients and it is related to a worse haemodynamic profile, characterized by PH and elevated PCWP. Moreover, after adjustment for age, it was a significant determinant of HF hospitalization during follow-up in our population. Junctional LGE can therefore represent a useful prognostic tool, as marker of adverse ventricular remodelling likely related to ventricular interdependence
Overcoming barriers to oral contraception in Italy an expert opinion to empower women
Oral contraceptives are among the most commonly used contraceptive methods. However, Italian women underused reliable hormonal contraceptives as compared with other European women. There is a need to streamline access to oral contraception, with expected benefits on emotional well-being of women and potential savings for health system in Italy. Indeed, women can only access to oral contraceptives through mandatory medical prescription. This is one of the most important barrier experienced by women. We hereby provide an expert opinion on the potential reclassification, extending pharmacy services to include responsible and appropriate use of POP, as an opportunity also in Italy to increase the use of safe and effective contraceptive methods

CD56 and PGP expression in acute myeloid leukemia: impact on clinical outcome
Overexpression of P-glycoprotein (PGP), a multidrug-related (MDR) protein, is one of the most important factors responsible for reduced drug sensitivity in acute myeloid leukemia (AML). Recently, we demonstrated that the presence of CD56 antigen, an isoform of the neural adhesion molecule, in AML cells is a negative independent prognostic factor for the achievement of complete remission (CR) and correlates with shorter survival. Since in our previous report we observed a more frequent PGP expression in CD56+ patients, we hypothesized that the reduced response to chemotherapy in this group of patients was due to increased PGP-mediated drug efflux. To confirm this hypothesis in this study PGP and CD56 expression on AML cells was correlated with other clinical and biological features and treatment response
Cardiac magnetic resonance imaging of arrhythmogenic cardiomyopathy: evolving diagnostic perspectives
Arrhythmogenic cardiomyopathy (ACM) is a genetically determined heart muscle disease characterized by fibro-fatty myocardial replacement, clinically associated with malignant ventricular arrhythmias and sudden cardiac death. Originally described a disease with a prevalent right ventricular (RV) involvement, subsequently two other phenotypes have been recognized, such as the left dominant and the biventricular phenotypes, for which a recent International Expert consensus document provided upgrade diagnostic criteria (the 2020 "Padua Criteria"). In this novel workup for the diagnosis of the entire spectrum of phenotypic variants of ACM, including left ventricular (LV) variants, cardiac magnetic resonance (CMR) has emerged as the cardiac imaging technique of choice, due to its capability of detailed morpho-functional and tissue characterization evaluation of both RV and LV. In this review, the key role of CMR in the diagnosis of ACM is outlined, including the supplemental value for the characterization of the disease variants. An ACM-specific CMR study protocol, as well as strengths and weaknesses of each imaging technique, is also provided. KEY POINTS: • Arrhythmogenic cardiomyopathy includes three different phenotypes: dominant right, biventricular, and dominant left. • In 2020, diagnostic criteria have been updated and cardiac magnetic resonance has emerged as the cardiac imaging technique of choice. • This aim of this review is to provide an update of the current state of art regarding the use of CMR in ACM, with a particular focus on novel diagnostic criteria, CMR protocols, and prognostic significance of CMR findings in ACM
Executive summary: Italian guidelines for diagnosis, risk stratification, and care continuity of fragility fractures 2021
Background: Fragility fractures are a major public health concern owing to their worrying and growing burden and their onerous burden upon health systems. There is now a substantial body of evidence that individuals who have already suffered a fragility fracture are at a greater risk for further fractures, thus suggesting the potential for secondary prevention in this field. Purpose: This guideline aims to provide evidence-based recommendations for recognizing, stratifying the risk, treating, and managing patients with fragility fracture. This is a summary version of the full Italian guideline. Methods: The Italian Fragility Fracture Team appointed by the Italian National Health Institute was employed from January 2020 to February 2021 to (i) identify previously published systematic reviews and guidelines on the field, (ii) formulate relevant clinical questions, (iii) systematically review literature and summarize evidence, (iv) draft the Evidence to Decision Framework, and (v) formulate recommendations. Results: Overall, 351 original papers were included in our systematic review to answer six clinical questions. Recommendations were categorized into issues concerning (i) frailty recognition as the cause of bone fracture, (ii) (re)fracture risk assessment, for prioritizing interventions, and (iii) treatment and management of patients experiencing fragility fractures. Six recommendations were overall developed, of which one, four, and one were of high, moderate, and low quality, respectively. Conclusions: The current guidelines provide guidance to support individualized management of patients experiencing non-traumatic bone fracture to benefit from secondary prevention of (re)fracture. Although our recommendations are based on the best available evidence, questionable quality evidence is still available for some relevant clinical questions, so future research has the potential to reduce uncertainty about the effects of intervention and the reasons for doing so at a reasonable cost
