Introduction: The prediction of ventricular tachyarrhythmias among patients with implantable cardioverter defibrillators is difficult with available clinical tools. We sought to assess whether in patients with heart failure (HF) and reduced ejection fraction with defibrillators, physiological sensor-based HF status, as summarized by the HeartLogic index, could predict appropriate device therapies., Methods: Five hundred and sixty-eight consecutive HF patients with defibrillators (n = 158, 28%) or cardiac resynchronization therapy-defibrillators (n = 410, 72%) were included in this prospective observational multicenter analysis. The association of both HeartLogic index and its physiological components with defibrillator shocks and overall appropriate therapies was assessed in regression and time-dependent Cox models., Results: Over a follow-up of 25 (15-35) months, 122 (21%) patients received an appropriate device therapy (shock, n = 74, 13%), while the HeartLogic index crossed the threshold value (alert, HeartLogic ≥ 16) 1200 times (0.71 alerts/patient-year) in 370 (65%) subjects. The occurrence of ≥1 HeartLogic alert was significantly associated with both appropriate shocks (Hazard ratios [HR]: 2.44, 95% confidence interval [CI]: 1.49-3.97, p = .003), and any appropriate defibrillator therapies. In multivariable time-dependent Cox models, weekly IN-alert state was the strongest predictor of appropriate defibrillator shocks (HR: 2.94, 95% CI: 1.73-5.01, p < .001) and overall therapies. Compared with stable patients, patients with appropriate shocks had significantly higher values of HeartLogic index, third heart sound amplitude, and resting heart rate 30-60 days before device therapy., Conclusion: The HeartLogic index is an independent dynamic predictor of appropriate defibrillator therapies. The combined index and its individual physiological components change before the arrhythmic event occurs., (© 2023 The Authors.

Aims: To investigate the use of guideline-directed medical therapies (GDMT) and associated outcomes in obese (body mass index ≥30 kg/m 2 ) versus non-obese patients with heart failure (HF) with reduced ejection fraction (HFrEF)., Methods and Results: Patients with HFrEF from the Swedish HF Registry were included. Of 16 116 patients, 24% were obese. In obese versus non-obese patients, use of treatments was 91% versus 86% for renin-angiotensin system inhibitors (RASi)/angiotensin receptor-neprilysin inhibitors (ARNi), 94% versus 91% for beta-blockers, 53% versus 43% for mineralocorticoid receptor antagonists. Obesity was shown to be independently associated with more likely use of each treatment, triple combination therapy, and the achievement of target dose by multivariable logistic regressions. Multivariable Cox regressions showed use of RASi/ARNi and beta-blockers being independently associated with lower risk of all-cause/cardiovascular death regardless of obesity, although, when considering competing risks, a lower risk of cardiovascular death with RASi/ARNi in obese versus non-obese patients was observed. RASi/ARNi were associated with lower risk of HF hospitalization in obese but not in non-obese patients, whereas beta-blockers were not associated with the risk of HF hospitalization regardless of obesity. At the competing risk analysis, RASi/ARNi use was associated with higher risk of HF hospitalization regardless of obesity., Conclusion: Obese patients were more likely to receive optimal treatments after adjustment for factors affecting tolerability, suggesting that perceived beyond actual tolerance issues limit GDMT implementation. RASi/ARNi and beta-blockers were associated with lower mortality regardless of obesity, with a greater association between RASi/ARNi and lower cardiovascular death in obese versus non-obese patients when considering competing risk., (© 2023 The Authors.

Non-invasive prenatal screening (NIPS) in twin gestations has been shown to have high detection rates and low false-positive rates for trisomy 21, as seen in singleton pregnancies, although there have been few large cohort twin studies, genome-wide studies in particular, to date. In this study, we looked at the performance of genome-wide NIPT in a large cohort consisting of 1244 twin pregnancy samples collected over a two-year period in a single laboratory in Italy. All samples underwent an NIPS for common trisomies, with 61.5% of study participants choosing to undergo genome-wide NIPS for additional fetal anomalies (namely, rare autosomal aneuploidies and CNVs). There were nine initial no-call results, all of which were resolved upon retest. Based on our NIPS results, 17 samples were at high risk for trisomy 21, one for trisomy 18, six for a rare autosomal aneuploidy, and four for a CNV. Clinical follow-up was available for 27 out of 29 high-risk cases; a sensitivity of 100%, a specificity of 99.9%, and a PPV of 94.4% were noted for trisomy 21. Clinical follow-up was also available for 1110 (96.6%) of the low-risk cases, all of which were true negatives. In conclusion, we found that NIPS was a reliable screening approach for trisomy 21 in twin pregnancies.

Aims: Patients with atrial fibrillation frequently experience sleep disorder breathing, and both conditions are highly prevalent in presence of heart failure (HF). We explored the association between the combination of an HF and a sleep apnoea (SA) index and the incidence of atrial high-rate events (AHRE) in patients with implantable defibrillators (ICDs)., Methods and Results: Data were prospectively collected from 411 consecutive HF patients with ICD. The IN-alert HF state was measured by the multi-sensor HeartLogic Index (>16), and the ICD-measured Respiratory Disturbance Index (RDI) was computed to identify severe SA. The endpoints were as follows: daily AHRE burden of ≥5 min, ≥6 h, and ≥23 h. During a median follow-up of 26 months, the time IN-alert HF state was 13% of the total observation period. The RDI value was ≥30 episodes/h (severe SA) during 58% of the observation period. An AHRE burden of ≥5 min/day was documented in 139 (34%) patients, ≥6 h/day in 89 (22%) patients, and ≥23 h/day in 68 (17%) patients. The IN-alert HF state was independently associated with AHRE regardless of the daily burden threshold: hazard ratios from 2.17 for ≥5 min/day to 3.43 for ≥23 h/day (P < 0.01). An RDI ≥ 30 episodes/h was associated only with AHRE burden ≥5 min/day [hazard ratio 1.55 (95% confidence interval: 1.11-2.16), P = 0.001]. The combination of IN-alert HF state and RDI ≥ 30 episodes/h accounted for only 6% of the follow-up period and was associated with high rates of AHRE occurrence (from 28 events/100 patient-years for AHRE burden ≥5 min/day to 22 events/100 patient-years for AHRE burden ≥23 h/day)., Conclusions: In HF patients, the occurrence of AHRE is independently associated with the ICD-measured IN-alert HF state and RDI ≥ 30 episodes/h. The coexistence of these two conditions occurs rarely but is associated with a very high rate of AHRE occurrence., Clinical Trial Registration: URL: http://clinicaltrials.gov/Identifier: NCT02275637., Competing Interests: Conflict of interest: M.

Aims: There is considerable variability in the effect of intravenous iron on hard cardiovascular (CV)-related outcomes in patients with heart failure (HF) in randomized controlled trials (RCTs). We use a meta-analytic approach to analyse data from existing RCTs to derive a more robust estimate of the effect size of intravenous iron infusion on CV-related outcomes in patients with HF., Method and Results: PubMed/Medline was searched using the following terms: ('intravenous' and 'iron' and 'heart failure') from inception till 6 November 2022 for RCTs comparing intravenous iron infusion with placebo or standard of care in patients with HF and iron deficiency. Outcomes were the composite of CV mortality and first hospitalization for HF; all-cause mortality; CV mortality; first hospitalization for HF; and total hospitalizations for HF. Random effects risk ratio (RR) with 95% confidence intervals (CIs) were calculated. Ten RCTs with a total of 3438 patients were included. Intravenous iron resulted in a significant reduction in the composite of CV mortality and first hospitalization for HF [RR 0.0.85; 95% CI (0.77, 0.95)], first hospitalization for HF [RR 0.82; 95% CI (0.67, 0.99)], and total hospitalizations for HF [RR 0.74; 95% CI (0.60, 0.91)] but no statistically significant difference in all-cause mortality [RR 0.95; 95% CI. (0.83, 1.09)] or CV mortality [OR 0.89; 95% CI (0.75, 1.05)]., Conclusions: Intravenous iron infusion in patients with HF reduces the composite risk of first hospitalization for HF and CV mortality as well as the risks of first and recurrent hospitalizations for HF, with no effect on all-cause mortality or CV mortality alone., (© 2023 The Authors.

Most primary cutaneous lymphomas consist of T-cell lymphomas or small cell lymphomas; however, the skin may also be affected by lymphomas with large cell morphology, as a primary or secondary localization. A minority of cases consist of primary cutaneous B-cell lymphomas (PCBCLs). PCBCLs are a heterogeneous group of rare neoplasms with an overlapping morphological and immunohistochemical picture of the different subtypes. Nevertheless, differential diagnosis in the setting of this group of neoplasms is mandatory to identify the correct therapy and prognosis, but it may be challenging since, due to the rarity of these neoplasms, they may not always be familiar to pathologists. Indeed, immunohistochemistry may not be enough to distinguish the different histotypes, which overlap in immunohistochemical features. Furthermore, the ever-increasing knowledge of the molecular features of systemic B-cell lymphomas, such as gene rearrangements with clinical significance, has led in recent years to further investigation into the molecular landscape of PCBCLs with large cell morphology. This work aimed to provide a practical diagnostic guide for pathologists dealing with primary cutaneous large B-cell lymphomas.

Some cancer patients display a less aggressive form of metastatic disease, characterized by a low tumor burden and involving a smaller number of sites, which is referred to as "oligometastatic disease" (OMD). This review discusses new biomarkers, as well as methodological challenges and perspectives characterizing OMD. Recent studies have revealed that specific microRNA profiles, chromosome patterns, driver gene mutations ( ERBB2 , PBRM1 , SETD2 , KRAS , PIK3CA , SMAD4 ), polymorphisms ( TCF7L2 ), and levels of immune cell infiltration into metastases, depending on the tumor type, are associated with an oligometastatic behavior. This suggests that OMD could be a distinct disease with specific biological and molecular characteristics. Therefore, the heterogeneity of initial tumor burden and inclusion of OMD patients in clinical trials pose a crucial methodological question that requires responses in the near future. Additionally, a solid understanding of the molecular and biological features of OMD will be necessary to support and complete the clinical staging systems, enabling a better distinction of metastatic behavior and tailored treatments.

Heart failure (HF) is a complex syndrome that affects mortality/morbidity and acts at different levels in the patient's life, resulting in a drastic impairment in multiple aspects of daily activities (e.g. physical, mental/emotional, and social) and leading to a reduction in quality of life. The definition of disease status and symptom severity has been traditionally based on the physician assessment, while the patient's experience of disease has been long overlooked. The active participation of patients in their own care is necessary to better understand the perception of disease and the multiple aspects of life affected, and to improve adherence to treatments. Patient-reported outcomes (PROs) aim to switch traditional care to a more patient-centred approach. Although PROs demonstrated precision in the evaluation of disease status and have a good association with prognosis in several randomized controlled trials, their implementation into clinical practice is limited. This review discusses the modalities of use of PROs in HF, summarizes the most largely adopted PROs in HF care, and provides an overview on the application of PROs in trials and the potential for their transition to clinical practice. By discussing the advantages and the disadvantages of their use, the reasons limiting their application in daily clinical routine, and the strategies that may promote their implementation, this review aims to foster the systematic integration of the patient's standpoint in HF care., (© 2023 The Authors.

Introduction: We studied the predictive and prognostic influences of hypertension (HT), type 2 diabetes (T2D), weight, and p53 mutations in metastatic colorectal cancer (CRC) patients., Patients and Methods: T2D was diagnosed according to the ADA criteria. HT was classified according to the ACC/AHA guidelines. BMI (body-mass index) was calculated and classified according to the WHO criteria. TruSigt™Oncology 500 kit was applied to construct the genomic libraries for Next Generation Sequencing (NGS) analysis. The Illumina NovaSeq 6000 technological platform and the Illumina TruSight Oncology 500 bioinformatics pipeline were applied to analyze results. Overall survival (OS) was calculated through Kaplan-Meier curves. Univariate and multivariate analyses were performed to assess the relationships between clinical and/or molecular covariates. Associations between HT, T2D, BMI, p53, and clinical variables were evaluated by the χ2 test. P < 0.05 were considered statistically significant., Results: Two-hundred-forty-four patients were enrolled. One-hundred-twenty (49.2%), 110 (45.1%), and 50 (20.5%) patients were affected by overweight, HT, and T2D, respectively. DC (disease control) was achieved more frequently in patients without T2D (83.1%) compared to the diabetic ones (16.9%) ( P = 0.0246). DC, KRAS mutational status, T2D, BMI, and concomitant presence of T2D, BMI, and HT associated with survival ( P < 0.05). At multivariate analysis, age (≥65 vs. <65 years), response to first-line chemotherapy (DC vs. no DC), and concomitant presence of T2D, BMI, and HT (HR: 4.56; 95% CI: 2.40-8.67; P = 0.0217) emerged as independent prognostic variables. P53 was mutated in 31/53 analyzed cases (60.4%). The most frequent gene variants were p.Arg175His and p.Cys135Tyr. High BMI (>25 kg/m 2 ) associated with occurrence of p53 mutations ( P < 0.0001). P53 mutated patients presented a worse prognosis compared to the wild-type ones (HR: 3.21; 95% CI: 1.43-7.23; P = 0.0047)., Conclusion: Diabetic, hypertensive and overweight metastatic CRC patients are a negative prognostic subgroup deserving specific therapeutic strategies. P53 mutations associate with prognosis and BMI unrevealing complex and unexplored connections between metabolism and cancer occurrence., Competing Interests: LC, GS, MI, MCasi, and NP are employed by AMES, Centro Polidiagnostico Strumentale srl, Naples, Italy.

Heart Failure (HF) is a multi-faceted and life-threatening syndrome characterized by significant morbidity and mortality, poor functional capacity and quality of life, and high costs. HF affects more than 64 million people worldwide. Therefore, attempts to decrease its social and economic burden have become a major global public health priority. While the incidence of HF has stabilized and seems to be declining in industrialized countries, the prevalence is increasing due to the ageing of the population, improved treatment of and survival with ischaemic heart disease, and the availability of effective evidence-based therapies prolonging life in patients with HF. There are geographical variations in HF epidemiology. There is substantial lack of data from developing countries, where HF exhibits different features compared with that observed in the Western world. In this review, we provide a contemporary overview on the global burden of HF, providing updated estimates on prevalence, incidence, outcomes, and costs worldwide., Competing Interests: Conflict of interest: A.C. declares no conflicts related to this work.

Background: We aimed to evaluate patient preferences towards three oral antihyperglycaemic therapies using conjoint analysis to determine which attributes may influence use., Methods: We used an online survey, completed by 553 US respondents with type 2 diabetes mellitus (T2DM; mean age 64 ± 9 years; 55% had cardiovascular [CV] risk; 27% had CV disease), to present hypothetical, blinded, pairwise, drug profile comparison choices, between different benefit/risk attributes and effect ranges. Attributes were derived from phase 3 trials for empagliflozin 25 mg (SGLT2 inhibitor), oral semaglutide 14 mg (GLP-1 receptor agonist) and sitagliptin 100 mg (DPP-4 inhibitor). Predicted therapy preference outcomes and relative importance of each attribute were calculated (presented as a percentage)., Results: Preference score was highest for the profile matching empagliflozin (56%), versus sitagliptin (38%; z-test, P < 0.001) and oral semaglutide (6%, z-test, P < 0.001). Results were overall consistent in subgroup analyses. Genital infection risk was the most important attribute (relative score: 19% [z-test, P = 0.077]). Other important attributes were fasting requirements (15%), weight reduction (15%), risk of vomiting (14%), CV benefit (12%), and risk of nausea (11%). HbA1c reduction (8%) and ability to take medication with other drugs (6%) were considered less important. While blinded to drug name/dose, respondents chose a drug profile similar to empagliflozin (41%) versus sitagliptin (31%), oral semaglutide (11%), or 'none of the options' (17%)., Conclusion: While the drug profile comparable to empagliflozin was preferred, CV benefit was not the top patient priority. A shared physician-patient decision model and increased patient education are needed to ensure optimal use of guideline-directed T2DM therapies., (Copyright © 2022 The Author(s).

Endothelial dysfunction (ED) causes worse prognoses in heart failure (HF) patients treated with cardiac resynchronization therapy (CRTd). ED triggers the downregulation of microRNA-130 (miR-130a-5p), which targets endothelin-1 (ET-1). Thus, we evaluated ED and the response to CRTd by assessing miR-130a-5p and ET-1 serum levels. We designed a prospective multi-center study with a 1-year follow-up to evaluate ED, ET-1, and miR-130a-5p in CRTd patients with ED (ED-CRTd) vs. patients without ED (NED-CRTd). Clinical outcomes were CRTd response, HF hospitalization, cardiac death, and all-cause death. At 1-year follow-up, NED-CRTd (n = 541) vs. ED-CRTd (n = 326) patients showed better clinical statuses, lower serum values of B type natriuretic peptide (BNP: 266.25 ± 10.8 vs. 297.43 ± 16.22 pg/mL; p < 0.05) and ET-1 (4.57 ± 0.17 vs. 5.41 ± 0.24 pmol/L; p < 0.05), and higher values of miR-130a-5p (0.51 ± 0.029 vs. 0.41 ± 0.034 A.U; p < 0.05). Compared with NED-CRTd patients, ED-CRTd patients were less likely to be CRTd responders (189 (58%) vs. 380 (70.2%); p < 0.05) and had higher rates of HF hospitalization (115 (35.3%) vs. 154 (28.5%); p < 0.05) and cardiac deaths (30 (9.2%) vs. 21 (3.9%); p < 0.05). Higher miR-130a-5p levels (HR 1.490, CI 95% [1.014−2.188]) significantly predicted CRTd response; the presence of hypertension (HR 0.818, CI 95% [0.669−0.999]), and displaying higher levels of ET-1 (HR 0.859, CI 98% [0.839−0.979]), lymphocytes (HR 0.820, CI 95% [0.758−0.987]), LVEF (HR 0.876, CI 95% [0.760−0.992]), and ED (HR 0.751, CI 95% [0.624−0.905]) predicted CRTd non-response. Higher serum miR-130a-5p levels (HR 0.332, CI 95% [0.347−0.804]) and use of ARNI (HR 0.319, CI 95% [0.310−0.572]) predicted lower risk of HF hospitalization, whereas hypertension (HR 1.818, CI 95% [1.720−2.907]), higher BNP levels (HR 1.210, CI 95% [1.000−1.401]), and presence of ED (HR 1.905, CI 95% [1.238−2.241]) predicted a higher risk of HF hospitalization. Hence, serum miR-130a-5p could identify different stages of ED and independently predict CRTd response, therefore representing a novel prognostic HF biomarker.

Background: Guidelines recommend early initiation of multiple guideline-directed medical therapies (GDMTs) to reduce mortality/rehospitalization in patients with heart failure and reduced ejection fraction. Understanding GDMT use is critical to improving clinical practice., Objectives: This study sought to describe GDMT use in Japan, Sweden, and the United States in contemporary real-world settings., Methods: EVOLUTION HF (Utilization of Dapagliflozin and Other Guideline Directed Medical Therapies in Heart Failure Patients: A Multinational Observational Study Based on Secondary Data) is an observational cohort study using routine-care databases. Patients initiating any GDMT within 12 months of a hospitalization for heart failure (hHF) discharge were included. Dapagliflozin (the only sodium-glucose cotransporter-2 inhibitor approved at study onset), sacubitril/valsartan, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, and mineralocorticoid receptor antagonists (MRAs) were considered separately. Doses and discontinuation were assessed in the 12 months following initiation. Target dose was defined as ≥100% of the guideline-recommended dose., Results: Overall, 266,589 patients were included. Mean times from hHF to GDMT initiation were longer for novel GDMTs (dapagliflozin or sacubitril/valsartan) than for other GDMTs: 39 and 44 vs 12 to 13 days (Japan), 44 and 33 vs 22 to 31 days (Sweden), and 33 and 19 vs 18 to 24 days (United States). Pooled across countries, proportions of patients who discontinued therapy (not including switches from ACE inhibitor or ARB to sacubitril/valsartan) within 12 months were 23.5% (dapagliflozin), 26.4% (sacubitril/valsartan), 38.4% (ACE inhibitors), 33.4% (ARBs), 25.2% (beta-blockers), and 42.2% (MRAs). Corresponding target dose achievements were 75.7%, 28.2%, 20.1%, 6.7%, 7.2%, and 5.1%, respectively., Conclusions: Initiation of novel GDMTs is delayed compared with other GDMTs. Few patients received target doses of GDMTs requiring uptitration. Persistence was higher for dapagliflozin than other GDMTs., Competing Interests: Funding Support and Author Disclosures EVOLUTION HF is funded by AstraZeneca.

Iron deficiency (ID) is common in patients with cardiovascular disease. Up to 60% of patients with coronary artery disease, and an even higher proportion of those with heart failure (HF) or pulmonary hypertension have ID; the evidence for cerebrovascular disease, aortic stenosis and atrial fibrillation is less robust. The prevalence of ID increases with the severity of cardiac and renal dysfunction and is probably more common amongst women. Insufficient dietary iron, reduced iron absorption due to increases in hepcidin secondary to the low-grade inflammation associated with atherosclerosis and congestion or reduced gastric acidity, and increased blood loss due to anti-thrombotic therapy or gastro-intestinal or renal disease may all cause ID. For older people in the general population and patients with HF with reduced ejection fraction (HFrEF), both anaemia and ID are associated with a poor prognosis; each may confer independent risk. There is growing evidence that ID is an important therapeutic target for patients with HFrEF, even if they do not have anaemia. Whether this is also true for other HF phenotypes or patients with cardiovascular disease in general is currently unknown. Randomized trials showed that intravenous ferric carboxymaltose improved symptoms, health-related quality of life and exercise capacity and reduced hospitalizations for worsening HF in patients with HFrEF and mildly reduced ejection fraction (<50%). Since ID is easy to treat and is effective for patients with HFrEF, such patients should be investigated for possible ID. This recommendation may extend to other populations in the light of evidence from future trials., Competing Interests: Conflict of interest: G.S. reports grants and personal fees from Vifor and AstraZeneca, grants and non-financial support from Boehringer Ingelheim; personal fees from Società Prodotti Antibiotici, Roche, Servier, GENESIS, Cytokinetics, and Medtronic; grants from Novartis, Boston Scientific, PHARMACOSMOS, Merck, and Bayer, outside the submitted work.

Background: Play is among the most frequently observed distorted behaviors in victims of Adverse Childhood Experiences (ACEs). Terr's (1981) studies helped to describe this behavioral distortion as post-traumatic child's play (PTCP). This study aimed to evaluate whether child victims of Adverse Childhood Experiences (ACEs) engaging in semi-structured play present the markers of post-traumatic child's play (PTCP) during the administration of the Manchester Child Attachment Story Task (MCAST), whose playful stories activate the attachment system. Methods: The sample comprised 17 child victims of ACEs (mean age = 6.76). Children were evaluated using the Manchester Child Attachment Story Task. Results: The analysis of the play clearly revealed the presence of markers associated with the characteristics of the post-traumatic play described by Terr (1981), namely, repetition, revisiting, hyperarousal, and danger. In particular, the intrusiveness dimension was observed, which can be identified in the post-traumatic play by the presence of recurrent memories, dreams, and dissociative symptoms. Conclusions: Post-traumatic play is characterized by repetition, containing aspects, scenes, or sequences of the traumatic event, expressed explicitly or symbolically.

Aims: Type 2 diabetes (T2DM) in patients with coronavirus disease-19 (COVID-19) is associated with a worse prognosis. We separately investigated the associations between the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and dipeptidyl peptidase-4 inhibitors (DPP-4i), and the risk of COVID-19 hospitalization and death., Methods and Results: Patients with T2DM registered in the Swedish National Patient Registry and alive on 1 February 2020 were included. 'Incident severe COVID-19' was defined as the first hospitalization and/or death from COVID-19. A modified Poisson regression approach was applied to a 1:1 propensity score-matched population receiving vs. not receiving SGLT2i, GLP-1 RA, and DPP-4i to analyse the associations between their use and (I) incident severe COVID-19 and (II) risk of 30-day mortality in patients hospitalized for COVID-19.Among 344 413 patients, 39 172 (11%) were treated with SGLT2i, 34 290 (10%) with GLP-1 RA, and 53 044 (15%) with DPP-4i; 9538 (2.8%) had incident severe COVID-19 by 15 May 2021. SGLT2i and DPP-4i were associated with a 10% and 11% higher risk of incident severe COVID-19, respectively, whereas there was no association for GLP-1 RA. DPP-4i was also associated with a 10% higher 30-day mortality in patients hospitalized for COVID-19, whereas there was no association for SGLT2i and GLP-1 RA., Conclusion: SGLT2i and DPP-4i use were associated with a higher risk of incident severe COVID-19. DPP-4i use was associated with higher 30-day mortality in patients with COVID-19, whereas SGLT2i use was not. No increased risk for any outcome was observed with GLP-1 RA., (© The Author(s) 2022.

Aims: Digoxin is included in some heart failure (HF) guidelines but controversy persists about the true role for and impact of treatment with this drug, particularly in the absence of atrial fibrillation (AF). The aim of this study was to assess the association between clinical characteristics and digoxin use and between digoxin use and mortality/morbidity in a large, contemporary cohort of patients with HF with reduced ejection fraction (HFrEF) stratified by history of AF., Methods and Results: Patients with HFrEF (EF < 40%) enrolled in the Swedish HF registry between 2005 and 2018 were analysed. The independent association between digoxin use and patient characteristics was assessed by logistic regression, and between digoxin use and outcomes [composite of all-cause mortality or HF hospitalization (HFH), all-cause mortality, and HFH] by Cox regressions in a 1:1 propensity score matched population. Digoxin use was analysed at baseline and as a time-dependent variable. Of 42 456 patients with HFrEF, 16% received digoxin, 29% in the AF group and 2.8% in the non-AF group. The main independent predictors of use were advanced HF, higher heart rate, history of AF, preserved renal function, and concomitant use of beta blockers. Digoxin use was associated with lower risk of all-cause death/HFH [hazard ratio (HR): 0.95; 95% confidence interval (CI): 0.91-0.99] in AF, but with higher risk in non-AF (HR: 1.24; 95% CI: 1.09-1.43). Consistent results were observed when digoxin use was analysed as a time-dependent variable., Conclusion: The great majority of digoxin users had a history of AF. Digoxin use was associated with lower mortality/morbidity in patients with AF, but with higher mortality/morbidity in patients without AF., (© The Author(s) 2021.

Aims: Pre-clinical congestion markers of worsening heart failure (HF) can be monitored by devices and may support the management of patients with HF. We aimed to assess whether congestion-guided HF management according to device-based remote monitoring strategies is more effective than standard therapy., Methods and Results: A comprehensive literature research for randomized controlled trials (RCTs) comparing device-based remote monitoring strategies for congestion-guided HF management versus standard therapy was performed on PubMed, Embase, and CENTRAL databases. Incidence rate ratios (IRRs) and associated 95% confidence intervals (CIs) were calculated using the Poisson regression model with random study effects. The primary outcome was a composite of all-cause death and HF hospitalizations. Secondary endpoints included the individual components of the primary outcome. A total of 4347 patients from eight RCTs were included. Findings varied according to the type of parameters monitored. Compared with standard therapy, haemodynamic-guided strategy (4 trials, 2224 patients, 12-month follow-up) reduced the risk of the primary composite outcome (IRR 0.79, 95% CI 0.70-0.89) and HF hospitalizations (IRR 0.76, 95% CI 0.67-0.86), without a significant impact on all-cause death (IRR 0.93, 95% CI 0.72-1.21). In contrast, impedance-guided strategy (4 trials, 2123 patients, 19-month follow-up) did not provide significant benefits., Conclusion: Haemodynamic-guided HF management is associated with better clinical outcomes as compared to standard clinical care., (© 2022 The Authors.

Background: Several studies have investigated the topic of emotion regulation and self-perception in women during pregnancy, which turns out to be a critical event for the woman approaching psycho-physical changes. The objectives of the study were the evaluation and monitoring, during pregnancy, of emotional states and levels of self-efficacy and the analysis of the representations of self and the child., Methods: Twenty women (M = 34.60; SD = 4.60) in the 28-week gestation period participated in the research. We performed three administrations (T0-1-2) of an ad hoc questionnaire containing: personal data; Maternal Representations in Pregnancy Interview-IRMAG; Multidimensional Emotion Questionnaire-MEQ; Perceived Self-Efficacy in Complex Situations Scale., Results: Both qualitative and quantitative analyses show that the future mother's strategies and functional resources focus on perceiving herself as effective in the acquired role, despite the pregnancy itself being a highly stressful critical event. Positive emotions tend to increase, just as the frequency, intensity, persistence and regulation of emotion undergo a linear and constant increase with respect to the first and second administration., Conclusions: Qualitative research has produced significant results with regard to the representations of mothers-to-be as they attempt to cope with states of change during pregnancy with their own personal adaptive resources.

Background Heart failure (HF) has a dramatic impact on worldwide health care systems that is determined by the growing prevalence of and the high exposure to cardiovascular and noncardiovascular events. Prognosis remains poor. We sought to compare a large population with HF across the ejection fraction (EF) spectrum with a population without HF for patient characteristics, and HF, cardiovascular, and noncardiovascular outcomes. Methods and Results Patients with HF registered in the Swedish HF registry in 2005 to 2018 were compared 1:3 with a sex-, age-, and county-matched population without HF. Outcomes were cardiovascular and noncardiovascular mortality and hospitalizations. Of 76 453 patients with HF, 53% had reduced EF, 23% mildly reduced EF, and 24% preserved EF. Compared with those without HF, patients with HF had more cardiovascular and noncardiovascular comorbidities and worse socioeconomic status. Incidence of cardiovascular and noncardiovascular events was higher in people with HF versus non-HF, with increased risk of all-cause (hazard ratio [HR], 2.53 [95% CI, 2.50-2.56]), cardiovascular (HR, 4.67 [95% CI, 4.59-4.76]), and noncardiovascular (HR, 1.49 [95% CI, 1.46-1.52]) mortality, 2- to 5-fold higher risk of first/repeated cardiovascular and noncardiovascular hospitalizations, and ~4 times longer in-hospital length of stay for any cause. Patients with HF with reduced EF had higher risk of HF hospitalizations, whereas those with HF with preserved EF had higher risk of all-cause and noncardiovascular hospitalization and mortality. Conclusions Patients with HF exert a high health care burden, with a much higher risk of cardiovascular, all-cause, and noncardiovascular events, and nearly 4 times as many days spent in hospital compared with those without HF. These epidemiological data may enable strategies for optimal resource allocation and HF trial design.

Purpose: To assess the qualitative relationship between liquid biopsy and conventional tissue biopsy. As a secondary target, we evaluated the relationship between the liquid biopsy results and the T stage, N stage, M stage, and compared to grading. Methods: The Local Ethics Committee of the “Università degli Studi della Campania Luigi Vanvitelli”, with the internal resolution number 24997/2020 of 12.11.2020, approved this spontaneous prospective study. According to the approved protocol, patients with lung cancer who underwent Fine-Needle Aspiration Cytology (FNAC), CT-guided biopsy, and liquid biopsy were enrolled. A Yates chi-square test was employed to analyze differences in percentage values of categorical variables. A p-value < 0.05 was considered statistically significant. Data analysis was performed using the Matlab Statistic Toolbox (The MathWorks, Inc., Natick, MA, USA). Results: When a genetic mutation is present on the pathological examination, this was also detected on the liquid biopsy. ROS1 and PDL1 mutations were found in 2/29 patients, while EGFR Exon 21 was identified in a single patient. At liquid biopsy, 26 mutations were identified in the analyzed samples. The mutations with the highest prevalence rate in the study populations were: ALK (Ile1461Val), found in 28/29 patients (96.6%), EML4 (Lys398Arg), identified in 16/29 (55.2%) patients, ALK (Asp1529Glu), found in 14/29 (48.3%) patients, EGFR (Arg521Lys), found in 12/29 (41.4%) patients, ROS (Lys2228Gln), identified in 11/29 (37.9%) patients, ROS (Arg167Gln) and ROS (Ser2229Cys), identified in 10/29 (34.5%) patients, ALK (Lys1491Arg) and PIK3CA (Ile391Met), identified in 8/29 (27.6%) patients, ROS (Thr145Pro), identified in 6/29 (20.7%) patients, and ROS (Ser1109Leu), identified in 4/29 (13.8%) patients. No statistically significant differences can be observed in the mutation rate between the adenocarcinoma population and the squamous carcinoma population (p > 0.05, Yates chi-square test). Conclusions: We showed that, when a genetic mutation was detected in pathological examination, this was always detected by liquid biopsy, demonstrating a very high concordance rate of genomic testing between tissues and their corresponding mutations obtained by liquid biopsy, without cases of false-negative results. In addition, in our study, liquid biopsy highlighted 26 mutations, with the prevalence of ALK mutation in 96.6% of patients, supporting the idea that this approach could be an effective tool in cases with insufficient tumor tissue specimens or in cases where tissue specimens are not obtainable.

A 34 year-old young man came to our attention after an occasional finding of complete AV block. We made the diagnosis of systemic sarcoidosis with cardiac involvement through an FDG-PET even with a normal CMR. We started corticosteroid therapy and we decided to follow-up the patient through an implantable loop recorder (ILR). Beyond an initial regression of the AV block, after 8 months the ILR revealed AV block and pauses more than 3 s during the day; a new FDG-PET evidenced FDG uptake in new areas of left ventricle. Hence we started infliximab and implanted a dual chamber ICD.

Aims: To evaluate the quality of heart failure (HF) care using the European Society of Cardiology (ESC) quality indicators (QIs) for HF and to assess whether better quality of care is associated with improved outcomes., Methods and Results: We performed a nationwide cohort study using the Swedish HF registry, consisting of patients with any type of HF at their first outpatient visit or hospitalization. Independent participant data for quality of HF care was evaluated against the ESC QIs for HF, and association with mortality estimated using multivariable Cox regression. In total, 43 704 patients from 80 hospitals across Sweden enrolled between 2013-2019 were included, with median follow-up 23.6 months. Of the 16 QIs for HF, 13 could be measured and 5 were inversely associated with all-cause mortality during follow-up. Higher attainment (≥50% vs. <50% attainment) of the composite opportunity-based score (combination of QIs into a single score) for patients with reduced ejection fraction was associated with lower all-cause mortality (adjusted hazard ratio 0.81; 95% confidence interval 0.72-0.91). Attainment of the composite score was less in the outpatient than inpatient setting (adjusted odds ratio 0.85; 95% confidence interval 0.72-0.99). Quality of care varied across hospitals, with assessment of health-related quality of life being the indicator with the widest variation in attainment (interquartile range 61.7%)., Conclusion: Quality of HF care may be measured using the ESC HF QIs. In Sweden, attainment of HF care evaluated using the QIs demonstrated between and within hospital variation, and many QIs were inversely associated with mortality., (© 2022 The Authors.

Aim: Half of heart failure (HF) patients have chronic kidney disease (CKD) complicating their pharmacological management. We evaluated physicians' and patients' patterns of use of evidence-based medical therapies in HF across CKD stages., Methods and Results: We studied HF patients with reduced (HFrEF) and mildly reduced (HFmrEF) ejection fraction enrolled in the Swedish Heart Failure Registry in 2009-2018. We investigated the likelihood of physicians to prescribe guideline-recommended therapies to patients with CKD, and of patients to fill the prescriptions within 90 days of incident HF (initiating therapy), to adhere (proportion of days covered ≥80%) and persist (continued use) on these treatments during the first year of therapy. We identified 31 668 patients with HFrEF (median age 74 years, 46% CKD). The proportions receiving a prescription for angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (ACEi/ARB/ARNi) were 96%, 92%, 86%, and 68%, for estimated glomerular filtration rate (eGFR) ≥60, 45-59, 30-44, and <30 ml/min/1.73 m 2 , respectively; for beta-blockers 94%, 93%, 92%, and 92%, for mineralocorticoid receptor antagonists (MRAs) 45%, 44%, 37%, 24%; and for triple therapy (combination of ACEi/ARB/ARNi + beta-blockers + MRA) 38%, 35%, 28%, and 15%. Patients with CKD were less likely to initiate these medications, and less likely to adhere to and persist on ACEi/ARB/ARNi, MRA, and triple therapy. Among stoppers, CKD patients were less likely to restart these medications. Results were consistent after multivariable adjustment and in patients with HFmrEF (n = 15 114)., Conclusions: Patients with HF and CKD are less likely to be prescribed and to fill prescriptions for evidence-based therapies, showing lower adherence and persistence, even at eGFR categories where these therapies are recommended and have shown efficacy in clinical trials., (© 2022 The Authors.

Aims: To investigate incidence, predictors and prognostic implications of longitudinal New York Heart Association (NYHA) class changes (i.e. improving or worsening vs. stable NYHA class) in heart failure (HF) across the ejection fraction (EF) spectrum., Methods and Results: From the Swedish HF Registry, 13 535 patients with EF and ≥2 NYHA class assessments were considered. Multivariable multinomial regressions were fitted to identify the independent predictors of NYHA change. Over a 1-year follow-up, 69% of patients had stable, 17% improved, and 14% worsened NYHA class. Follow-up in specialty care predicted improving NYHA class, whereas an in-hospital patient registration, lower EF, renal disease, lower mean arterial pressure, older age, and longer HF duration predicted worsening. The association between NYHA change and subsequent outcomes was assessed with multivariable Cox models. When adjusting for the NYHA class at baseline, improving NYHA class was independently associated with lower while worsening with higher risk of all-cause and cardiovascular mortality, and first HF hospitalization. After adjustment for the NYHA class at follow-up, NYHA class change did not predict morbidity/mortality. NYHA class assessment at baseline and follow-up predicted morbidity/mortality on top of the changes. Results were consistent across the EF spectrum., Conclusion: In a large real-world HF population, NYHA class trajectories predicted morbidity/mortality after extensive adjustments. However, the prognostic role was entirely explained by the resulting NYHA class, i.e. the follow-up value. Our results highlight that considering one-time NYHA class assessment, rather than trajectories, might be the preferable approach in clinical practice and for clinical trial design., (© 2022 The Authors.

Background: Heart failure (HF) trials have stringent inclusion and exclusion criteria, but limited data exist regarding generalizability of trials. We compared patient characteristics and outcomes between patients with HF and reduced ejection fraction (HFrEF) in trials and observational registries., Methods and Results: Individual patient data for 16 922 patients from five randomized clinical trials and 46 914 patients from two HF registries were included. The registry patients were categorized into trial-eligible and non-eligible groups using the most commonly used inclusion and exclusion criteria. A total of 26 104 (56%) registry patients fulfilled the eligibility criteria. Unadjusted all-cause mortality rates at 1 year were lowest in the trial population (7%), followed by trial-eligible patients (12%) and trial-non-eligible registry patients (26%). After adjustment for age and sex, all-cause mortality rates were similar between trial participants and trial-eligible registry patients [standardized mortality ratio (SMR) 0.97; 95% confidence interval (CI) 0.92-1.03] but cardiovascular mortality was higher in trial participants (SMR 1.19; 1.12-1.27). After full case-mix adjustment, the SMR for cardiovascular mortality remained higher in the trials at 1.28 (1.20-1.37) compared to RCT-eligible registry patients., Conclusion: In contemporary HF registries, over half of HFrEF patients would have been eligible for trial enrolment. Crude clinical event rates were lower in the trials, but, after adjustment for case-mix, trial participants had similar rates of survival as registries. Despite this, they had about 30% higher cardiovascular mortality rates. Age and sex were the main drivers of differences in clinical outcomes between HF trials and observational HF registries., (© The Author(s) 2021.

Aims: Exercise stress testing can stratify specific populations of heart failure patients for mortality risk, but is not universally applied. The aim of the present study was to investigate the prognostic capabilities of invasive exercise testing in a real-world cohort of suspected heart failure patients in whom non-cardiac causes of dyspnea were excluded. Methods: We retrospectively analyzed the survival of 682 patients who underwent right heart catheterization at rest and during exercise between 2007 and 2017 for dyspnea and expected heart failure. Pulmonary capillary wedge pressure (PCWP) at rest and the PCWP response to exercise, expressed as the ratio of PCWP at peak exercise to workload normalized to body weight (PCWL (mmHg/W/kg)), were determined. Mortality data were retrieved from the official German death registry. Results: Over a median follow-up period of 8.5 years, PCWL is a stronger predictor of all-cause mortality than PCWP. Patients featuring a reduced left ventricular ejection fraction (LVEF; <50%), but favorable response to exercise (PCWL <34.7 mmHg/W/kg), have a similar mortality risk to patients with a normal LVEF and low PCWL (hazard ratio (HR) 1.180, 95% CI 0.48−2.91, p = 0.719). Irrespective of LVEF, an increased PCWL during exercise was associated with a significantly increased mortality (HR 1.950 with preserved LVEF, 95% CI 1.12−3.34, p = 0.018; and HR 3.212 with impaired LVEF, 95% CI 1.75−5.70, p < 0.001). Conclusions: In patients with clinical heart failure, invasive exercise testing improves the prediction of mortality. Subjects with a favorable response to exercise have a relatively low mortality irrespective of left ventricular systolic function.

Sodium-glucose cotransporter 2 inhibitors were first discovered as glucose-lowering drugs because of their glycosuric action and good safety profile. Subsequently, they were studied in cardiovascular outcome trials in people with type 2 diabetes, and their cardiovascular benefit was consistently observed as regards heart failure hospitalizations and cardiovascular death. Investigation of the underlying mechanisms granting such benefit is continuously engaging researchers all over the world. The findings described in this article paved the way to a larger use of these drugs in patients with heart failure, with the aim of improving their clinical outcomes and quality of life., Competing Interests: Disclosure The authors have no conflict of interest to disclose in relation to this present work.

Congestion is a cardinal sign of heart failure (HF). In the past, it was seen as a homogeneous epiphenomenon that identified patients with advanced HF. However, current evidence shows that congestion in HF varies in quantity and distribution. This updated view advocates for a congestive-driven classification of HF according to onset (acute vs. chronic), regional distribution (systemic vs. pulmonary), compartment of distribution (intravascular vs. extravascular), and clinical vs. subclinical. Thus, this review will focus on the utility of circulating biomarkers for assessing and managing the different fluid overload phenotypes. This discussion focused on the clinical utility of the natriuretic peptides, carbohydrate antigen 125 (also called mucin 16), bio-adrenomedullin and mid-regional pro-adrenomedullin, ST2 (also known as interleukin-1 receptor-like 1), cluster of differentiation 146, troponin, C-terminal pro-endothelin-1, and parameters of haemoconcentration. The utility of circulation biomarkers on top of clinical evaluation, haemodynamics, and imaging needs to be better determined by dedicated studies. Some multiparametric frameworks in which these tools contribute to management are proposed., (© 2022 European Society of Cardiology.)

Heart failure (HF) is a long-term clinical syndrome, with increasing prevalence and considerable healthcare costs that are further expected to increase dramatically. Despite significant advances in therapy and prevention, mortality and morbidity remain high and quality of life poor. Epidemiological data, that is, prevalence, incidence, mortality, and morbidity, show geographical variations across the European countries, depending on differences in aetiology, clinical characteristics, and treatment. However, data on the prevalence of the disease are scarce, as are those on quality of life. For these reasons, the ESC-HFA has developed a position paper to comprehensively assess our understanding of the burden of HF in Europe, in order to guide future policies for this syndrome. This manuscript will discuss the available epidemiological data on HF prevalence, outcomes, and human costs-in terms of quality of life-in European countries., (© 2022 The Authors.

Background: Differences in clinically important thresholds in patient-reported outcomes measures such as the Kansas City Cardiomyopathy Questionnaire (KCCQ) remain less well-established in patients with heart failure with preserved ejection fraction (HFpEF) versus heart failure with reduced ejection fraction (HFrEF)., Objectives: The purpose of this study was to estimate meaningful thresholds for improvement or deterioration in the KCCQ-Total Symptom Score (TSS) in patients with HFrEF versus HFpEF., Methods: This secondary analysis of EMPERIAL program used anchor- and distribution-based approaches to estimate thresholds for improvement or deterioration in the KCCQ-TSS using Patient Global Impression of Severity (PGIS) as the primary anchor. Mean change in KCCQ-TSS from baseline to week 12 was calculated for each PGIS., Results: A total of 312 HFrEF and 315 HFpEF patients were enrolled. At week 12, mean changes in KCCQ-TSS corresponding to PGIS changes of "any improvement," "1-category improvement," and "1-category deterioration" were 13 ± 17, 12 ± 17, -3 ± 16 points in HFrEF, and 15 ± 18, 13 ± 17, -7 ± 18 points in HFpEF. Threshold for meaningful within-patient change in KCCQ-TSS was ≥9 points in HFrEF and ≥7 points in HFpEF patients. Sensitivity and specificity of ≥9 points/≥7 points change was 0.65 and 0.70 for HFrEF and 0.64 and 0.66 for HFpEF. Cumulative distribution function curves of KCCQ-TSS change from baseline to week 12 showed a shift to higher scores in both HFrEF and HFpEF patients., Conclusions: In the EMPERIAL program, a change in KCCQ-TSS of ≥9 points in HFrEF and ≥7 points in HFpEF represents the minimal clinically important difference for improvement, confirming the broad range of 5-10 points as meaningful thresholds., Competing Interests: Funding Support and Author Disclosures The EMPERIAL trials were sponsored by Boehringer Ingelheim.

Aims: To investigate the association between catheter ablation for atrial fibrillation (AF) and mortality as well as hospitalization for heart failure (HF) in patients with HF across the ejection fraction (EF) spectrum., Methods and Results: Patients with first-time catheter ablation for AF (ablation group) compared to only medical treated AF patients (no ablation group) were identified from the Swedish Heart Failure Registry between 2005 and 2019. The primary outcome (all-cause mortality/first HF hospitalization) was assessed by Cox regression models in a 1:2 propensity score (PS) matched cohort and pre-specified EF subgroups (preserved EF [≥50%], mildly reduced EF [40-49%], reduced EF [&lt;40%]) of this cohort. A total of 452 patients in the ablation group and 43 766 patients in the no ablation group were identified. After PS matching, 434 patients in the ablation group were compared to 868 patients in the no ablation group. Over a median follow-up of 2.6 years (0.0-14.1 years), catheter ablation was associated with a lower risk of the primary outcome (all-cause mortality/first HF hospitalization) (hazard ratio [HR] 0.78, 95% confidence interval [CI] 0.65-0.94). Results were consistent across all EF subgroups. In HF with preserved EF (HFpEF), catheter ablation was also associated with a lower risk of recurrent HF hospitalization (incidence rate ratio 0.17, 95% CI 0.07-0.42)., Conclusion: In HF patients across the EF spectrum, catheter ablation for AF was associated with lower risk of the primary outcome (all-cause mortality/first HF hospitalization). This study supports catheter ablation as a treatment option for AF in HF patients, including those with HFpEF., (© 2022 European Society of Cardiology.)

The historical classification of heart failure (HF) has considered two distinct subgroups, HF with reduced ejection fraction (HFrEF), generally classified as EF below 40%, and HF with preserved ejection fraction (HFpEF) variably classified as EF above 40%, 45% or 50%. One of the principal reasons behind this distinction was related to presence of effective therapy in HFrEF, but not in HFpEF. Recently the expanding knowledge in the specific subgroup of patient with a LVEF between 41% and 49% and the potential benefit of new therapies and of those used in patients with LVEF below 40%, has led to rename this group as HF with mildly reduced EF (HFmrEF). In this review we discuss the reasons behind this modification, we summarize the main characteristics of HFmrEF the similarities and differences with the two other EF categories, and finally we provide a comprehensive overview of the current available evidence supporting the treatment of patients with HFmrEF., (Copyright © 2022.

Sudden death is a devastating complication of heart failure (HF). Current guidelines recommend an implantable cardioverter-defibrillator (ICD) for prevention of sudden death in patients with HF and reduced ejection fraction (HFrEF) specifically those with a left ventricular ejection fraction ≤35% after at least 3 months of optimized HF treatment. The benefit of ICD in patients with symptomatic HFrEF caused by coronary artery disease has been well documented; however, the evidence for a benefit of prophylactic ICD implantation in patients with HFrEF of non-ischaemic aetiology is less strong. Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, beta-blockers (BB), and mineralocorticoid receptor antagonists (MRA) block the deleterious actions of angiotensin II, norepinephrine, and aldosterone, respectively. Neprilysin inhibition potentiates the actions of endogenous natriuretic peptides that mitigate adverse ventricular remodelling. BB, MRA, angiotensin receptor-neprilysin inhibitor (ARNI) have a favourable effect on reduction of sudden cardiac death in HFrEF. Recent data suggest a beneficial effect of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in reducing serious ventricular arrhythmias and sudden cardiac death in patients with HFrEF. So, in the current era of new drugs for HFrEF and with the optimal use of disease-modifying therapies (BB, MRA, ARNI and SGLT2i), we might need to reconsider the need and timing for use of ICD as primary prevention of sudden death, especially in HF of non-ischaemic aetiology., (© 2022 European Society of Cardiology.)

Background: Following the availability of new drugs for chronic heart failure (HF) with reduced ejection fraction (HFrEF), we sought to provide an updated and comparative synthesis of the evidence on HFrEF pharmacotherapy efficacy., Methods: We performed a Bayesian network meta-analysis of phase 2 and 3 randomized controlled trials (RCTs) of medical therapy in HFrEF patient cohorts with more than 90% of the participants with left ventricular ejection fraction less than 45% and all-cause mortality reported., Results: Sixty-nine RCTs, accounting for 91,741 subjects, were evaluated. The step-wise introduction of new drugs progressively decreased the risk of all-cause death, up to reaching a random-effects hazard ratio (HR) of 0.43 (95% credible intervals [CrI] 0.27-0.63) with beta blockers (BB), angiotensin-converting enzyme inhibitors (ACEi), and mineralocorticoid receptor antagonist (MRA) versus placebo. The risk was further reduced by adding sodium-glucose cotransporter-2 inhibitors (SGLT2i; HR 0.38, 95% CrI 0.22-0.60), ivabradine (HR 0.39, 95% CrI 0.21-0.64), or vericiguat (HR 0.40, 95% CrI 0.22-0.65) to neurohormonal inhibitors, and by angiotensin receptor-neprilysin inhibitor (ARNI), BB, and MRA (HR 0.36, 95% CrI 0.20-0.60). In a sensitivity analysis considering the ARNI and non-ARNI subgroups of SGLT2i RCTs, the combination SGLT2i + ARNI + BB + MRA was associated with the lowest HR (0.28, 95% CrI 0.16-0.45 vs. 0.40, 95% CrI 0.24-0.60 for SGLT2i + BB + ACEi + MRA). Consistent results were obtained in sensitivity analyses and by calculating surface under the cumulative ranking area, as well as for cardiovascular mortality (information available for 56 RCTs), HF hospitalization (45 RCTs), and all-cause hospitalization (26 RCTs)., Conclusions: Combination medical therapy including neurohormonal inhibitors and newer drugs, especially ARNI and SGLT2i, confers the maximum benefit with regard to HFrEF prognosis., (© 2022 The Authors.

Background: Patients hospitalized for acute heart failure (AHF) may receive different care depending on type of ward. We describe temporal changes in triage of HF patients with preserved, mildly reduced, and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF) hospitalized for AHF to cardiology versus noncardiology wards in Sweden., Methods: We analyzed temporal changes in ward type for AHF for HFrEF versus HFmrEF versus HFpEF between 2000 and 2016., Results: Among 37 918 patients with AHF, 19 777 (52%) had HFrEF, 7712 (20%) had HFmrEF, and 10 429 (28%) had HFpEF. Overall, 19 646 (52%) were hospitalized in cardiology and 18 272 (48%) in noncardiology. The proportions hospitalized in noncardiology in 2000 to 2004 versus in 2013 to 2016 were for HFrEF: 45 versus 47%, for HFmrEF: 52 versus 56%, and for HFpEF: 46 versus 64%, respectively. The overall proportion of HFrEF in 2000 to 2004 versus in 2013 to 2016 decreased (60% versus 49%) especially in noncardiology (58% versus 41%), whereas the overall proportion of HFpEF increased (20% versus 30%) especially in noncardiology (21% versus 37%). The average age and prevalence of comorbidities also increased over time, with older patients with multiple comorbidities being more frequently admitted to noncardiology wards., Conclusions: Over time, AHF hospitalization for HFpEF occurred increasingly in noncardiology, whereas for HFrEF and HFmrEF the proportions of patients treated in cardiology versus noncardiology were substantially unchanged over time. This may have implications for implementation of emerging HFpEF therapy.

Aims: No biomarker has achieved widespread acceptance as a surrogate endpoint for early-phase heart failure (HF) trials. We assessed whether changes over time in a panel of plasma biomarkers were associated with subsequent morbidity/mortality in HF with reduced ejection fraction (HFrEF)., Methods and Results: In 1040 patients with HFrEF from the BIOSTAT-CHF cohort, we investigated the associations between changes in the plasma concentrations of 30 biomarkers, before (baseline) and after (9 months) attempted optimization of guideline-recommended therapy, on top of the BIOSTAT risk score and the subsequent risk of HF hospitalization/all-cause mortality using Cox regression models. C-statistics were calculated to assess discriminatory power of biomarker changes/month-nine assessment. Changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and WAP four-disulphide core domain protein HE4 (WAP-4C) were the only independent predictors of the outcome after adjusting for their baseline plasma concentration, 28 other biomarkers (both baseline and changes), and BIOSTAT risk score at baseline. When adjusting for month-nine rather than baseline biomarkers concentrations, only changes in NT-proBNP were independently associated with the outcome. The C-statistic of the model including the BIOSTAT risk score and NT-proBNP increased by 4% when changes were considered on top of baseline concentrations and by 1% when changes in NT-proBNP were considered on top of its month-nine concentrations and the BIOSTAT risk score., Conclusions: Among 30 relevant biomarkers, a change over time was significantly and independently associated with HF hospitalization/all-cause death only for NT-proBNP. Changes over time were modestly more prognostic than baseline or end-values alone. Changes in biomarkers should be further explored as potential surrogate endpoints in early phase HF trials., (© 2022 The Authors.

Type 2 diabetes mellitus (T2DM) is highly prevalent and associated with a two-fold increased mortality, mostly explained by cardiovascular diseases. Trial evidence on older glucose-lowering agents such as metformin and sulfonylureas is limited in terms of cardiovascular efficacy. Since 2008, after rosiglitazone was observed to increase the risk of myocardial infarction and heart failure (HF), cardiovascular outcome trials (CVOTs) have been required by regulators for licensing new glucose-lowering agents. In the following CVOTs, dipeptidyl peptidase 4 inhibitors (DPP4i) have been shown to be safe but not to improve mortality/morbidity, except for saxagliptin which increased the risk of HF. Several glucagon-like peptide-1 receptor agonists (GLP1-Ra) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been demonstrated to reduce the risk of cardiovascular mortality and morbidity. SGLT2i have shown a class effect for the reduction in risk of HF events in patients with T2DM, leading to trials testing their efficacy/safety in HF regardless of T2DM. In the DAPA-HF and the EMPEROR-Reduced trials dapagliflozin and empagliflozin, respectively, improved cardiovascular mortality/morbidity in patients with HF with reduced ejection fraction (HFrEF), with and without T2DM. Therefore, these drugs are now key part of HFrEF pharmacotherapy. In the SOLOIST-WHF, sotagliflozin reduced cardiovascular mortality/morbidity in patients with T2DM and a recent acute episode of HF regardless of ejection fraction (EF). In the EMPEROR-Preserved, empagliflozin reduced CV mortality/morbidity in patients with heart failure with mildly reduced (HFmrEF) and preserved (HFpEF) EF regardless of comorbid T2DM. The DELIVER is currently testing dapagliflozin in patients with HFmrEF and HFrEF. A strong renal protective role of SGLT2i has also emerged in trials enrolling patients with and without T2DM., (Published on behalf of the European Society of Cardiology.

Background: We previously reported rare regressive genetic trajectories of KRAS pathogenic mutations as a specific hallmark of the genuine oligometastatic status in colorectal cancer (CRC)., Methods: Survival and prognostic impact of disease extent in 140 metastatic CRC patients were evaluated through the Kaplan-Meyer curves and the Log-Rank test. KRAS mutations were assessed through the Illumina NovaSeq 6000 platform and TruSight™ Oncology 500 kit. HLA typing was carried out by PCR with sequence-specific oligonucleotides. Lymphocyte densities in tumors were expressed as cells per square millimeter. NKs isolated and CD8 + from NK-depleted PBMCs were characterized through flow cytometry. CD107a externalization was evaluated as NKs/CD8 cytotoxicity toward human colon cancer cells HT29, SW620, HCT116, and LS174T carrying different KRAS mutations., Results: The oligometastatic status was a strong and independent variable for survival (HR: 0.08 vs. polymetastatic disease; 95% CI: 0.02-0.26; p  < 0.001). Eighteen oligometastatic patients were selected. Twelve were alive at the last follow-up, and 9 were characterized. Genetic regression of KRAS was observed in 3 patients: patient (PAT)2, PAT5, and PAT8. PAT2 and PAT5 presented the highest levels of GrzB + lymphocytes in the tumor cores of the metastases (120 ± 11.2 and 132 ± 12.2 cells/mm 2 , respectively). Six out of 9 patients (67%), including PAT2 and PAT5, expressed HLA-C7. Twopatients (PAT2 and PAT5) presented high CD3 + /CD8 + -dependent cytotoxicity against HLA-C7+ SW620 cells (p.G12V-mutated cells), which was consistent with their observed mutational regression (p.G12V/p.G13D in primary→p.G13D in metastatic tumor)., Conclusions: We provide evidence that CD3 + /CD8 + lymphocytes from oligometastatic CRC patients display differential cytotoxicity against human colon cancer cells carrying KRAS mutations. This could provide an interesting basis for monitoring oligometastatic disease and developing future adoptive immunotherapies., Competing Interests: GSa, MI, MaC, and NP are employed by AMES, Centro Polidiagnostico Strumentale srl, Naples, Italy.

Background: This study explores the implicit theories by which primary caregivers (PC) of patients diagnosed with anorexia nervosa (AN) understand the eating disorder and interpret their role in treating and managing the problem., Methodology: In-depth, semi-structured, and open interview questions were used to achieve the study's goals. In total, 19 caregivers, 16 mothers, and three fathers (mean age: 50.74; SD: 5.248) from a public service for the treatment of behavioral disorders in southern Italy were interviewed. A lexical correspondence analysis (LCA) was applied to the verbatim transcripts to identify the main factorial dimensions, which organize similarity and dissimilarity in the collected discourses., Results: The first dimension represents the dialectic between two different models of explanation of the problem, and the second dimension represents the dialectic between two different perspectives on the attribution of responsibility. Overall, the analyses show the difficulties of PC in exploring the emotional dynamics of the problem and the tendency to take out of the family context every possible representation of the role that it can play in the maintenance and evolution of the disorder., Conclusions: The strategies to prevent and treat AN may benefit from knowledge of the meaning's lenses adopted by the primary caregivers to explain and cope with their daughters' illness.

Aims: Use of implantable cardioverter-defibrillators (ICD) for primary prevention of sudden cardiac death (SCD) in heart failure with reduced ejection fraction (HFrEF) is limited. We aimed to investigate barriers to ICD use in HFrEF while considering the predicted risk of mortality and SCD., Method and Results: Patients from the SwedeHF registered in 2011-2018 and with an indication for primary prevention ICD were analysed. The Seattle Proportional Risk and Seattle Heart Failure Models were used to predict the proportional SCD and all-cause mortality risk, respectively. A multivariable logistic regression model was fitted to identify independent predictors of ICD use/non-use; Cox regression models to evaluate the interaction between predicted SCD/mortality risk and ICD use for mortality. Of 13 475 patients, only 15.5% had an ICD. Those with higher predicted proportional SCD risk (>45%) had an ∼80% higher likelihood to have an ICD. Other predictors of non-use were follow-up in primary versus specialty care, higher comorbidity burden and lower socioeconomic status. ICD use was associated with lower mortality only in patients with higher predicted SCD and lower mortality risk (34% and 37% relative risk reduction for 3-year all-cause and cardiovascular mortality, respectively). In this subgroup of patients, underuse of ICD was 81.8%., Conclusion: In a contemporary registry, only 15.5% of patients with an indication for primary prevention ICD received the device. While a high predicted proportional SCD risk was appropriately linked to ICD use, the lack of specialized follow-up, higher comorbidity burden, and lower socioeconomic status were major unjustified impediments to implementation. Our findings suggest areas for improving ICD use for primary prevention of SCD in clinical practice., (© 2022 The Authors.
