Data on iron overload status and change thresholds that can predict mortality in patients with transfusion-dependent β-thalassemia (TDT) are limited. This was a retrospective cohort study of 912 TDT patients followed for up to 10 years at treatment centers in Italy (median age 32 years, 51.6% female). The crude mortality rate was 2.9%. Following best-predictive threshold identification through receiver operating characteristic curve analyses, data from multivariate Cox-regression models showed that patients with Period Average Serum Ferritin (SF) > 2145 vs ≤ 2145 ng/mL were 7.1-fold (P < 0.001) or with Absolute Change SF > 1330 vs ≤ 1330 ng/mL increase were 21.5-fold (P < 0.001) more likely to die from any cause. Patients with Period Average Liver Iron Concentration (LIC) > 8 vs ≤ 8 mg/g were 20.2-fold (P < 0.001) or with Absolute Change LIC > 1.4 vs ≤ 1.4 mg/g increase were 27.6-fold (P < 0.001) more likely to die from any cause. Patients with Index (first) cardiac T2* (cT2*) < 27 vs ≥ 27 ms were 8.6-fold (P < 0.001) more likely to die from any cause. Similarly, results at varying thresholds were identified for death from cardiovascular disease. These findings should support decisions on iron chelation therapy by establishing treatment targets, including safe iron levels and clinically meaningful changes over time. [ABSTRACT FROM AUTHOR]

Objective The main aim of this study was to define the best treatment option for multisystem inflammatory syndrome in children (MIS-C) and to analyse the role of anakinra. Methods This is a multicentre retrospective cohort study. Patients were treated according to the attending physician's decision. The patients were divided into four groups on the basis of the first treatment at time of admittance: (i) IVIG, (ii) IVIG and methylprednisolone (≤2 mg/kg/day), (iii) IVIG with high-dose methylprednisolone (>2 mg/kg/day) and (iv) anakinra with or without IVIG and/or methylprednisolone. Primary outcomes were defined as the presence of at least one of the following features: death, the failure of initial treatment, meaning the need for additional treatment for clinical worsening and cardiac involvement at the end of follow-up. Results Two hundred thirty-nine patients were recruited. At univariate analysis, persistent heart involvement at discharge was more frequent in those not receiving anakinra as initial treatment (3/21 vs 66/189; P  = 0.047). After comparisons between the four treatment regimens, adjusting for the propensity score, we observed that early treatment with anakinra was associated with a lower probability of developing persistent heart disease at the end of follow-up (odds ratio: 0.6; 95% CI: 0.4–1.0). Conclusion We report that early treatment with anakinra is safe and very effective in patients with severe MIS-C. In addition, our study suggests that early treatment with anakinra is the most favourable option for patients with a higher risk of developing a severe disease outcome. [ABSTRACT FROM AUTHOR]

Simple Summary: Porcupine quill injuries are common in dogs; however, intracardiac quill migration is rare. Considering the high rate of complications secondary to quill penetration and migration, veterinarians should be aware of risks associated with long-standing foreign bodies even when no clinical signs are evident. A dog was referred for three episodes of recurrent fever that resolved with antibiotic therapy. Ultrasonography and computed tomography revealed a single linear hyperechoic structure traversing the interventricular septum from the heart base to the cardiac apex. A median sternotomy was performed, and a porcupine quill was removed under a direct ultrasound guide. The dog recovered uneventfully. Dogs without evidence of severe cardiac injury secondary to a single intracardiac quill may have a good prognosis. The porcupine is a nocturnal quill-bearing rodent common throughout Italy. When threatened, it defends itself by erecting its quills, rattling its tail, and running sideways or backyard into predators. The quills are released upon contact with assailants and tend to migrate into several body tissues or cavities due to the unique inverted cuticles (crenate) directed downwards to the quill base (a sort of "harpoon effect"). Intracardiac migration of porcupine quills has been reported in a few dogs with severe clinical signs. This case report describes a single porcupine quill [Hystrix cristata, (HC)] migration through the heart in a dog and the use of multimodality imaging for the diagnosis and surgical approach. A 4-year-old 25 kg female mixed-breed dog was presented for evaluation of recurrent fever. Transthoracic echocardiographic examination showed a linear, hyperechoic foreign body traversing the interventricular septum from the heart base to the cardiac apex. Computed tomography and transesophageal echocardiography confirmed the presence of a single structure resembling a quill; a later esophageal endoscopy showed no anatomical alterations or mucosal injuries. Following median sternotomy and after accurate localization by intraoperative ultrasound, the quill was successfully removed. The dog had a good recovery without evidence of severe cardiac injury secondary to an intracardiac quill. To the best of the authors' knowledge, the identification of an intracardiac HC quill by ultrasonography and CT and its successful removal by ultrasound guide has not been previously reported.

Background: Multisystem inflammatory syndrome in children (MIS-C) is a novel condition temporally associated with SARS-CoV2 infection. Cardiovascular involvement is mainly evident as acute myocardial dysfunction in MIS-C. The aim of this study was to describe the cardiac dysfunction in patients with MIS-C, defining the role of severity in the clinical presentations and outcomes in a single cohort of pediatric patients. Methods: A single-center retrospective study on patients diagnosed with MIS-C, according to the Center for Disease Control and Prevention (CDC) definition, and referred to Vittore Buzzi Children's Hospital in Milan from November 2020 to February 2021. Patients were managed according to a local approved protocol. According to the admission cardiac left ventricular ejection fraction (LVEF), the patients were divided into group A (LVEF < 45%) and group B (LVEF ≥45%). Pre-existing, clinical, and laboratory factors were assessed for evaluating outcomes at discharge. Results: Thirty-two patients were considered. Cardiac manifestations of MIS-C were reported in 26 patients (81%). Group A included 10 patients (9 M/1F, aged 13 years [IQR 5–15]), and group B included 22 patients (15 M/7 M, aged 9 years [IQR 7–13]). Significant differences were noted among clinical presentations (shock, diarrhea, intensive care unit admission), laboratory markers (leucocytes, neutrophils, and protein C-reactive), and cardiac markers (troponin T and N-terminal pro B-type Natriuretic Peptide) between the groups, with higher compromission in Group A. We found electrocardiogram anomalies in 14 patients (44%) and rhythm alterations in 3 patients (9%), without differences between groups. Mitral regurgitation and coronary involvement were more prevalent in group A. Total length of hospital stay and cardiac recovery time were not statistically different between groups. A recovery of cardiac functioning was reached in all patients. Conclusion: Despite significant differences in clinical presentations and need for intensive care, all of the MIS-C patients with significant cardiac involvement in this study completely recovered. This suggests that the heart is an involved organ and did not influence prognosis if properly treated and supported in the acute phase. [ABSTRACT FROM AUTHOR]

Background: Rare diseases are chronic and life-threatening disorders affecting < 1 person every 2,000. For most of them, clinical symptoms and signs can be observed at birth or childhood. Approximately 80% of all rare diseases have a genetic background and most of them are monogenic conditions. In addition, while the majority of these diseases is still incurable, early diagnosis and specific treatment can improve patients' quality of life. Transplantation is among the therapeutic options and represents the definitive treatment for end-stage organ failure, both in children and adults. The aim of this paper was to analyze, in a large cohort of Italian patients, the main rare genetic diseases that led to organ transplantation, specifically pointing the attention on the pediatric cohort. Results: To the purpose of our analysis, we considered heart, lung, liver and kidney transplants included in the Transplant Registry (TR) of the Italian National Transplantation Center in the 2002–2019 timeframe. Overall, 49,404 recipients were enrolled in the cohort, 5.1% of whom in the pediatric age. For 40,909 (82.8%) transplant recipients, a disease diagnosis was available, of which 38,615 in the adult cohort, while 8,495 patients (17.2%) were undiagnosed. There were 128 disease categories, and of these, 117 were listed in the main rare disease databases. In the pediatric cohort, 2,294 (5.6%) patients had a disease diagnosis: of the 2,126 (92.7%) patients affected by a rare disease, 1,402 (61.1%) presented with a monogenic condition. As expected, the frequencies of pathologies leading to organ failure were different between the pediatric and the adult cohort. Moreover, the pediatric group was characterized, compared to the adult one, by an overall better survival of the graft at ten years after transplant, with the only exception of lung transplants. When comparing survival considering rare vs non-rare diseases or rare and monogenic vs rare non-monogenic conditions, no differences were highlighted for kidney and lung transplants, while rare diseases had a better survival in liver as opposed to heart transplants. Conclusions: This work represents the first national survey analyzing the main genetic causes and frequencies of rare and/or monogenic diseases leading to organ failure and requiring transplantation both in adults and children.

Rationale: About 50% of hospitalized coronavirus disease 2019 (COVID-19) patients with diabetes mellitus (DM) developed myocardial damage. The mechanisms of direct SARS-CoV-2 cardiomyocyte infection include viral invasion via ACE2-Spike glycoprotein-binding. In DM patients, the impact of glycation of ACE2 on cardiomyocyte invasion by SARS-CoV-2 can be of high importance. Objective: To evaluate the presence of SARS-CoV-2 in cardiomyocytes from heart autopsy of DM cases compared to Non-DM; to investigate the role of DM in SARS-COV-2 entry in cardiomyocytes. Methods and results: We evaluated consecutive autopsy cases, deceased for COVID-19, from Italy between Apr 30, 2020 and Jan 18, 2021. We evaluated SARS-CoV-2 in cardiomyocytes, expression of ACE2 (total and glycosylated form), and transmembrane protease serine protease-2 (TMPRSS2) protein. In order to study the role of diabetes on cardiomyocyte alterations, independently of COVID-19, we investigated ACE2, glycosylated ACE2, and TMPRSS2 proteins in cardiomyocytes from DM and Non-DM explanted-hearts. Finally, to investigate the effects of DM on ACE2 protein modification, an in vitro glycation study of recombinant human ACE2 (hACE2) was performed to evaluate the effects on binding to SARS-CoV-2 Spike protein. The authors included cardiac tissue from 97 autopsies. DM was diagnosed in 37 patients (38%). Fourth-seven out of 97 autopsies (48%) had SARS-CoV-2 RNA in cardiomyocytes. Thirty out of 37 DM autopsy cases (81%) and 17 out of 60 Non-DM autopsy cases (28%) had SARS-CoV-2 RNA in cardiomyocytes. Total ACE2, glycosylated ACE2, and TMPRSS2 protein expressions were higher in cardiomyocytes from autopsied and explanted hearts of DM than Non-DM. In vitro exposure of monomeric hACE2 to 120 mM glucose for 12 days led to non-enzymatic glycation of four lysine residues in the neck domain affecting the protein oligomerization. Conclusions: The upregulation of ACE2 expression (total and glycosylated forms) in DM cardiomyocytes, along with non-enzymatic glycation, could increase the susceptibility to COVID-19 infection in DM patients by favouring the cellular entry of SARS-CoV2.

We prospectively evaluated changes in cardiac and hepatic iron overload (IO) and in morpho-functional cardiac parameters and myocardial fibrosis by magnetic resonance imaging (MRI) in patients with low-risk and intermediate-1-risk myelodysplastic syndromes (MDS). Fifty patients enrolled in the Myocardial Iron Overload in MyElodysplastic Diseases (MIOMED) study were followed for 12 months. IO was quantified by the T2* technique and biventricular function parameters by cine images. Macroscopic myocardial fibrosis was detected by late gadolinium enhancement technique. Twenty-eight patients (71.89±8.46 years; 8 females) performed baseline and follow-up MRIs. Thirteen patients had baseline hepatic IO, with a higher frequency among transfusion-dependent patients. Out of the 15 patients with a baseline MRI liver iron concentration <3 mg/g/dw, two (non-chelated) developed hepatic IO. Thirteen (46.4%) patients had an abnormal T2* value in at least one myocardial segment. One patient without hepatic IO and non-transfused had baseline global T2* <20 ms. Among the 15 patients with no baseline myocardial IO (MIO), 2 worsened. There was a significant increase in both left and right ventricular end-diastolic volume indexes. Thirty-six percent of patients showed myocardial fibrosis correlating with aging. Two new occurrences were detected at the follow-up. In conclusion, by a more sensitive segmental approach, MIO is quite frequent in MDS patients and it can be present also in non-transfused patients and in absence of detectable hepatic iron. The incidence of cardiac and hepatic IO and of myocardial fibrosis and the increase in biventricular volumes after a 12-month interval suggest performing periodic MRI scans to better manage MDS patients.

The effect of post-conditioning with reduced glutathione (GSH, hepaval Italy/Ukraine) on myocardial contractility, oxygen cost, and mitochondrial factor release as a marker of mitochondrial permeability transition pore (MPTP) opening was studied in ischemia-reperfusion model at Langendorffisolated rat heart. It was found that reperfusion with Krebs- Henseleit solution containing GSH (10 mg / l) provided more complete restoration of the left ventricle developed pressure (70.2 and 56% at 5th and 40th min of reperfusion against 23.6 and 30.9% in control, P < 0.05 for both), reduced oxygen cost of myocardial work (184 and 157% at 5th and 40th min of reperfusion against 413 and 216% in control, P < 0.05 for both), and decreased the value of mitochondrial factor by 3 times, indicating inhibition of MPTP. It was shown that the level of GSH in cardiac tissues was significantly increased by 1.5 times 30 min after administration of hepaval (52 mg/kg) intraperitoneally, indicating accumulation of GSH from the bloodstream. Thus, we have shown that post-conditioning with GSH had cardioprotective effect, inhibited the formation of MPTP and can be used as a tool for correction of post-ischemic disturbances of heart function.

Background: Myocardial injury is frequent among patients hospitalized with coronavirus disease-2019 (COVID-19) and is associated with a poor prognosis. However, the mechanisms of myocardial injury remain unclear and prior studies have not reported cardiovascular imaging data.Objectives: This study sought to characterize the echocardiographic abnormalities associated with myocardial injury and their prognostic impact in patients with COVID-19.Methods: We conducted an international, multicenter cohort study including 7 hospitals in New York City and Milan of hospitalized patients with laboratory-confirmed COVID-19 who had undergone transthoracic echocardiographic (TTE) and electrocardiographic evaluation during their index hospitalization. Myocardial injury was defined as any elevation in cardiac troponin at the time of clinical presentation or during the hospitalization.Results: A total of 305 patients were included. Mean age was 63 years and 205 patients (67.2%) were male. Overall, myocardial injury was observed in 190 patients (62.3%). Compared with patients without myocardial injury, those with myocardial injury had more electrocardiographic abnormalities, higher inflammatory biomarkers and an increased prevalence of major echocardiographic abnormalities that included left ventricular wall motion abnormalities, global left ventricular dysfunction, left ventricular diastolic dysfunction grade II or III, right ventricular dysfunction and pericardial effusions. Rates of in-hospital mortality were 5.2%, 18.6%, and 31.7% in patients without myocardial injury, with myocardial injury without TTE abnormalities, and with myocardial injury and TTE abnormalities. Following multivariable adjustment, myocardial injury with TTE abnormalities was associated with higher risk of death but not myocardial injury without TTE abnormalities.Conclusions: Among patients with COVID-19 who underwent TTE, cardiac structural abnormalities were present in nearly two-thirds of patients with myocardial injury. Myocardial injury was associated with increased in-hospital mortality particularly if echocardiographic abnormalities were present. [ABSTRACT FROM AUTHOR]

• Human errors in Isotope Separation On-Line (ISOL) facility is performed. • Integrated approach of Hierarchical Task Analysis and Human Reliability Analysis is used. • A modified HEART approach is proposed. • HEART, SPAR-H, and CREAM are compared to each other. SPES (Selective Production of Exotic Species) is a second-generation Isotope Separation On-Line (ISOL) facility for advanced nuclear physics applications, currently under construction at INFN (National Institute of Nuclear Physics) of Legnaro, Italy. Despite the potentially important safety implications of human errors for ISOL facilities, only a limited number of studies addressing this issue have been performed worldwide. This paper tries to address this need by means of an integrated approach of Hierarchical Task Analysis (HTA) and three human error quantification methods: HEART (in an enhanced version), SPAR-H, and CREAM. The application of multiple Human Reliability Analysis (HRA) methods adds credibility to the analysis results and, for the present paper, this is required because the methods are applied to different performance conditions than typical, i.e. for operators in a nuclear power plant control room. The study emphasizes the potential range of task failure probabilities obtained in the analyses, rather than best-estimate values. Since the facility is being constructed, with elements such as the human-machine interface still undergoing design, some of the inputs typically required by HRA methods were not available; consequently, the produced HEP estimates may not fully represent future performance. The obtained results allowed informing some safety-enhancing recommendations that, coming at early stage, could be considered for implementation by the facility designers and managers.

This paper explores the political-administrative genesis of one of the major Italian public infrastructures of the twentieth century: Naples metro Line 1. It is highlighted in the period of time, the project has suffered, and at the same time, the choices of the different "political seasons" that the third city of Italy has undergone. From the beginning of the national railway system, which has become the best practice in terms of public transport, Line 1 has become, year after year, the heart of the Neapolitan and regional transport system, gaining international notoriety thanks to the so-called "Art Stations" and arriving today to transport over 45 million passengers / year.

Background and Aims: There are concerns that incretin-based antidiabetic drugs - including dipeptidyl peptidase 4 (DPP-4) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists - increase the risk of hospitalization for heart failure (HF). To further analyse this issue, we conducted a nested case-control study within a cohort of antidiabetic users in a real world setting.Methods and Results: Within a cohort of 133,639 subjects with a first prescription of an antidiabetic drug (new-users) between 2010 and 2016 in Lombardy, Italy, and were followed-up to 2016, we identified 4057 subjects with a first hospitalization for HF and 80,450 controls matched on sex, age, and date of cohort-entry. The multivariate odds ratios (ORs) of HF in relation to current use of incretin-based drugs as compared to current use of two or more oral antidiabetics was 1.06 (95% confidence interval, CI, 0.83-1.35), with no evidence of a trend in risk with increasing duration of use. The corresponding ORs were 1.10 (95% CI 0.85-1.41) for DPP-4 inhibitors and 0.84 (95% CI 0.48-1.47) for GLP-1 receptor agonists. Estimates were consistent in various sensitivity analyses.Conclusions: This study indicates that incretin-based drugs are not associated with an increased risk of hospitalization for HF, thus providing further reassurance on the cardiovascular safety of these antidiabetic drugs in the clinical practice.

Background: The hypoglossal canal is a dual bone canal at the cranial base near the occipital condyles. The filaments of the hypoglossal nerve pass through the canal. It also transmits the meningeal branch of the ascending pharyngeal artery, the venous plexus and meningeal branches of the hypoglossal nerve. The hypoglossal nerve innervates all the intrinsic and extrinsic muscles of the tongue except the palatoglossal and is fundamental in physiological functions as phonation and deglutition. A surgical approach to the canal requires knowledge of the main morphometric data by neurosurgeons., Methods: The present study was carried out on 50 adult dried skulls: 31 males: age range 18-85 years; 19 females: age range 26-79 years. The skulls came from the ''Leonetto Comparini'' Anatomical Museum. The skulls belonged to people from Siena (Italy) and its surroundings (1882-1932) and, therefore, of European ethnicity. The present study reports (a) the osteological variations in hypoglossal canal (b) the morphometry of hypoglossal canal and its relationship with occipital condyles. One skull had both the right and left hypoglossal canals occluded and, therefore, could not be evaluated. None of the skulls had undergone surgery., Results: We found a double canal in 16% of cases, unilaterally and bilaterally in 2% of cases. The mean length of the right and left hypoglossal canals was 8.46 mm. The mean diameter of the intracranial orifice and extracranial orifice of the right and left hypoglossal canals was 6.12 ± 1426 mm, and 6.39 ± 1495 mm. The mean distance from the intracranial end of the hypoglossal canal to the anterior and posterior ends of occipital condyles was 10,76 mm and 10,81 mm. The mean distance from the intracranial end of the hypoglossal canal to the inferior end of the occipital condyles was 7,65 mm., Conclusions: The study on the hypoglossal canal adds new osteological and morphometric data to the previous literature, mostly based on studies conducted on different ethnic groups.The data presented is compatible with neuroradiological studies and it can be useful for radiologists and neurosurgeons in planning procedures such as transcondilar surgery. The last purpose of the study is to build an Italian anatomical data base of the dimensions of the hypoglossal canal in dried skulls.., (© 2023. The Author(s).)

Endocrine complications of haemochromatosis and heart failure mostly affect morbidity and mortality in polytransfused patients. This study analyzes endocrine dysfunctions and the impact of GH-IGF-1 axis alteration on cardiac performance in a population of 31 patients. A retrospective study on 31 Caucasian polytransfused outpatients, 27 adults and 4 pediatric, residing in Apulia, Italy, followed from 2005 to 2016, was conducted. Patients underwent basal and dynamic hormonal evaluation. GHRH plus arginine test was performed in 21 patients (19 adults and 2 children). Among them, 9 patients were affected by left ventricle diastolic dysfunction and/or atrial or ventricular dilatation (HD group) and 12 patients did not have cardiovascular disease (non-HD group). Twenty-nine out of 31 patients (94%) had at least one endocrinopathy. We found severe or mild GH deficit (GHD) in all HD patients versus 3 patients in the non-HD group (p=0.001). Mean IGF-1 levels were significantly lower in the HD group than in non-HD subjects (53±30 versus 122±91 μg/L, p=0.04). Our study confirms the need to perform a dynamic evaluation of the GH-IGF1 axis in polytransfused patients, especially when heart dysfunction emerges. An intervention study with GH replacement therapy in a larger randomized adult population will clarify the role of GH/IGF axis on cardiovascular outcomes in this patient population.

The study aim was to assess predictors of negative antibody response (AbR) in solid organ transplant (SOT) recipients after the first booster of SARS-CoV-2 vaccination. Solid organ transplant recipients receiving SARS-CoV-2 vaccination were prospectively enrolled (March 2021–January 2022) at six hospitals in Italy and Spain. AbR was assessed at first dose (t 0), second dose (t 1), 3 ± 1 month (t 2), and 1 month after third dose (t 3). Negative AbR at t 3 was defined as an anti-receptor binding domain titre <45 BAU/mL. Machine learning models were developed to predict the individual risk of negative (vs. positive) AbR using age, type of transplant, time between transplant and vaccination, immunosuppressive drugs, type of vaccine, and graft function as covariates, subsequently assessed using a validation cohort. Overall, 1615 SOT recipients (1072 [66.3%] males; mean age±standard deviation [SD], 57.85 ± 13.77) were enrolled, and 1211 received three vaccination doses. Negative AbR rate decreased from 93.66% (886/946) to 21.90% (202/923) from t 0 to t 3. Univariate analysis showed that older patients (mean age, 60.21 ± 11.51 vs. 58.11 ± 13.08), anti-metabolites (57.9% vs. 35.1%), steroids (52.9% vs. 38.5%), recent transplantation (<3 years) (17.8% vs. 2.3%), and kidney, heart, or lung compared with liver transplantation (25%, 31.8%, 30.4% vs. 5.5%) had a higher likelihood of negative AbR. Machine learning (ML) algorithms showing best prediction performance were logistic regression (precision-recall curve-PRAUC mean 0.37 [95%CI 0.36–0.39]) and k-Nearest Neighbours (PRAUC 0.36 [0.35–0.37]). Almost a quarter of SOT recipients showed negative AbR after first booster dosage. Unfortunately, clinical information cannot efficiently predict negative AbR even with ML algorithms.

Background: The availability of ultra-miniaturized pocket ultrasound devices (PUD) adds diagnostic power to the clinical examination. Information on accuracy of ultrasound with handheld units in immediate differential diagnosis in emergency department (ED) is poor. The aim of this study is to test the usefulness and accuracy of lung ultrasound (LUS) alone or combined with ultrasound of the heart and inferior vena cava (IVC) using a PUD for the differential diagnosis of acute dyspnea (AD).Methods: We included 68 patients presenting to the ED of "Maurizio Bufalini" Hospital in Cesena (Italy) for AD. All patients underwent integrated ultrasound examination (IUE) of lung-heart-IVC, using PUD. The series was divided into patients with dyspnea of cardiac or non-cardiac origin. We used 2 × 2 contingency tables to analyze sensitivity, specificity, positive predictive value and negative predictive value of the three ultrasonic methods and their various combinations for the diagnosis of cardiogenic dyspnea (CD), comparing with the final diagnosis made by an independent emergency physician.Results: LUS alone exhibited a good sensitivity (92.6%) and specificity (80.5%). The highest accuracy (90%) for the diagnosis of CD was obtained with the combination of LUS and one of the other two methods (heart or IVC).Conclusions: The IUE with PUD is a useful extension of the clinical examination, can be readily available at the bedside or in ambulance, requires few minutes and has a reliable diagnostic discriminant ability in the setting of AD.

In recent decades, Heart of Darkness has become more and more influential across a great variety of media and cultures. Like Robinson Crusoe, Conrad's work has achieved the status of a modern myth, spawning countless adaptations. In Italy, Sergio Bonelli Editore, an Italian comic book publisher, has produced several graphic rewritings of Conrad's novella, which have appeared in the series Mr. No, Nathan Never, and Lilith. Taking their cue from Apocalypse Now, these works have adapted Heart of Darkness to new contexts while also acknowledging its continuing relevance. They have highlighted, with increasing emphasis, its importance as a document of the colonial exploitation. By making a didactic use of Heart of Darkness, moreover, Bonelli comic books have promoted the diffusion and canonization of Conrad in Italy. [ABSTRACT FROM AUTHOR]

Objectives: Myocardial dysfunction is a frequent complication in patients with severe sepsis and can worsen the prognosis. We investigated whether circulating biomarkers related to myocardial function and injury predicted outcome and were associated with albumin replacement.Design: A multicenter, randomized clinical trial about albumin replacement in severe sepsis or septic shock (the Albumin Italian Outcome Sepsis trial).Setting: Forty ICUs in Italy.Patients: Nine hundred and ninety-five patients with severe sepsis or septic shock.Interventions: Randomization to albumin and crystalloid solutions or crystalloid solutions alone.Measurements and Main Results: Plasma concentrations of N- terminal pro-B-type natriuretic peptide and high-sensitivity cardiac troponin T were measured 1, 2, and 7 days after enrollment. We tested the relationship of single marker measurements or changes over time with clinical events, organ dysfunctions, albumin replacement, and ICU or 90-day mortality in the overall population and after stratification by shock. N-terminal pro-B-type natriuretic peptide levels were abnormal in 97.4% of the patients and high-sensitivity cardiac troponin T in 84.5%, with higher concentrations in those with shock. After extensive adjustments, N-terminal pro-B-type natriuretic peptide concentrations predicted ICU or 90-day mortality, better than high-sensitivity cardiac troponin T. Early changes in N-terminal pro-B-type natriuretic peptide or high-sensitivity cardiac troponin T concentrations were independently associated with subsequent mortality in patients with shock. Patients given albumin had significantly higher N-terminal pro-B-type natriuretic peptide levels; in addition, early rise in N-terminal pro-B-type natriuretic peptide was associated with a better outcome in this subgroup.Conclusions: Circulating N-terminal pro-B-type natriuretic peptide and high-sensitivity cardiac troponin T are frequently elevated in severe sepsis or septic shock and have relevant prognostic value, which may be important in monitoring the clinical efficacy of supporting therapy.

Fingolimod is the first oral disease-modifying therapy approved for multiple sclerosis (MS). The risks associated with the use of fingolimod include cardiovascular adverse events (AEs). First-dose observation (FDO) is required for all patients for at least 6 hours. We describe FDO data and long-term cardiac tolerability in a cohort of fingolimod-treated relapsing MS patients. Two hundred and twelve patients started fingolimod 0.5 mg once daily. Before the first administration, all subjects had an electrocardiogram (ECG) with cardiologist interpretation. Following administration they were monitored for 6 hours and underwent a cardiac monitoring every 3 months. In this cohort, there was a heart rate reduction at the VI hour of 9.6 ± 8 beats per minute ( P < .001). Fifty-four individuals (25.5%) presented an abnormal ECG during the 6 hours. We experienced 1 case (0.22%) of symptomatic second-degree atrioventricular block. The mean follow-up period was 1.5 ± 0.7 years. During this period, 1 patient showed atrial fibrillation that needed to be treated. We also observed 5 cases of persistent increase in blood pressure. This postmarketing study shows that fingolimod is well tolerated and tha tcardiologic AEs are generally self-limited in the long term. [ABSTRACT FROM AUTHOR]

Background Obese adolescents with high proportion of visceral fat are at higher risk of developing the metabolic syndrome. Objectives The study aims to investigate if echocardiographic epicardial fat thickness ( EF) could be predictive of visceral obesity ( VO) early in life and to provide EF threshold values specific for male adolescents. Further aim was to investigate the association between EF, lifestyle and metabolic disease familiarity. Methods Anthropometric data were collected from 102 normal weight and overweight, healthy male adolescents (mean age: 14.91 ± 1.98 years); bioelectrical impedance analysis and transthoracic echocardiogram were performed in the same sample. Each participant fulfilled a validated self-administered lifestyle questionnaire. Results We found higher EF values in sedentary adolescents ( P < 0.05), in those who never eat fruit and vegetables ( P < 0.05), and in those with overweight mothers ( P < 0.05). The strongest independent predictor of EF was waist circumference ( P < 0.0001). Using the waist to height ratio as a marker of VO, logistic regression analysis revealed that 1 mm EF gain is responsible for seven times higher VO risk ( P < 0.0001). Receiver Operating Characteristic ( ROC) analysis showed that the optimal cut-off for EF thickness associated to youth VO is 3.2 mm. Conclusion Ultrasonography EF measurement might be a second-level assessment tool, useful to detect early cardiometabolic damage stage. [ABSTRACT FROM AUTHOR]

Background: Breast cancer in the elderly is associated with high recurrence and death rates, due mostly to undertreatment. Human epidermal growth factor receptor type 2 (HER2) overexpression is infrequent in older patients. Trastuzumab-based chemotherapy is often withheld from elderly patients because of its cardiotoxicity. Patients and Methods: Medical records of consecutive HER2-positive breast cancer patients aged ≥70 years old treated between 2005 and 2010 in the participating centers were retrospectively reviewed. All patients underwent multidimensional geriatric assessment (MGA). Results: Among 59 patients identified, 51 patients were evaluable (median age 76 years). The rate of any adverse event was 20% (10/51). The most relevant cardiac adverse event consisted of symptomatic congestive heart failure (CHF; n = 1, 2%) followed by asymptomatic decreases of left ventricular ejection fraction (LVEF; n = 6, 12%). Other toxicities included moderate hypersensitivity reactions during trastuzumab infusions (n = 3, 6%). Hypertension, obesity, prior anthracyclines exposure and concurrent chemotherapy were associated with a higher incidence of toxic events. Previous radiotherapy, concurrent endocrine therapy and different trastuzumab-based regimens did not seem to influence toxicity. Conclusions: Our data suggest that trastuzumab has a good safety profile in nonfrail women aged 70 years and older. These favorable findings may be related to a limited number of anthracycline pretreatments, patient selection and a close cardiologic monitoring. © 2013 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

OBJECTIVES Redo cardiac surgery has an increased risk of morbidity and mortality when compared with the initial operation. The aim of this study was to assess the impact of previous cardiac operations on patients undergoing transapical aortic valve implantation (TA-TAVI). METHODS We analysed data from 566 patients included in the Italian Registry of Transapical Aortic Valve Implantation who underwent TA-TAVI implantation with the Sapien valve (Edwards Lifesciences, Irvine, CA, USA) from April 2008 through May 2011. Of these, 110 patients (19.4%) had already undergone at least one previous cardiac operation with opening of the pericardium (group R) while for 456 patients (80.6%) TA-TAVI was the first cardiac procedure (group F). Data were prospectively collected at each of the 20 participating centres and then sent to a central database for storage and analysis. RESULTS Preoperative logistic EuroSCORE was higher in group R (35 ± 18.6 vs. 23.5 ± 11.9%; P < 0.001). Hospital mortality occurred in eight (7.2%) and 36 (7.9%) patients in groups R and F, respectively (P = 0.8). Mean follow-up was 10.4 ± 7.9 months (range: 1–34). Overall 2-year Kaplan–Meier survival was 64.2 ± 9.8 and 75.4 ± 3.5% in groups R and F, respectively (P = 0.69). Incidence of operative complications, postoperative bleeding, pacemaker implantation, myocardial infarction and stroke did not show statistically significant differences between groups. The univariate analysis showed that arterial hypertension, logistic EuroSCORE, porcelain aorta, left ventricular ejection fraction and previous percutaneous coronary interventions were significantly associated with 30-day mortality in group R. CONCLUSIONS According to our data, patients undergoing TAVI with previous cardiac operations have a higher preoperative risk profile but have similar outcomes when compared with patients undergoing a first operation. In these subset of patients, TAVI is a promising therapeutic option. [ABSTRACT FROM AUTHOR]

Background: The aim of the study was to assess the main determinant of the fall in blood pressure (BP) responsible for the head-up tilt testing-induced syncope. Methods and results: The study involved 200 patients (mean age 42 ± 3; 81 male) with syncope of unknown origin after the first evaluation. According to the response to the diagnostic tilt test, the population study was divided into four groups: Group I with mixed vasovagal syncope; Group II with cardioinhibitory syncope; Group III with vasodepressive syncope; Group IV: 40 patients with clinical syncope but no tilt-induced syncope. Finger arterial BP (Portapres, TNO, Amsterdam, the Netherlands) was recorded during tilt testing. Left ventricular stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) were computed from the pressure pulsations (Modelflow, TNO, Amsterdam, the Netherlands). During syncopal phase, the TPR decreased significantly in Group III, and increased in Group I and in Group II. CO decreased in Group I and in Group II and did not change significantly in Group III. SV decreased significantly in all groups. Conclusions: Our data showed that the arterial system appears to be the main determinant of the BP fall in vasodepressive vasovagal syncope; while the impaired constrictive response of the venous system, leading to reduced venous return to the heart, appears to be the main determinant of BP fall in mixed and cardioinhibitory vasovagal syncope.

Like many other serious acute cardiovascular and cerebrovascular events, acute myocardial infarction (AMI) shows seasonal variation, being most frequent in the winter. We sought to investigate whether age, gender, and hypertension influence this pattern. We studied 4014 (2259 male and 1755 female) consecutive patients with AMI presenting to St. Anna Hospital of Ferrara, Italy between January 1998 and December 2004. Some 1131 (28.2%) of the AMI occurred in persons vs. 56.6% in the ≥65 yr group (χ 2 =13.99; p [ABSTRACT FROM AUTHOR]

Background: Cardiac injury is common in patients who are hospitalized with coronavirus disease 2019 (COVID-19) and portends poorer prognosis. However, the mechanism and the type of myocardial damage associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain uncertain., Methods: We conducted a systematic pathological analysis of 40 hearts from hospitalized patients dying of COVID-19 in Bergamo, Italy, to determine the pathological mechanisms of cardiac injury. We divided the hearts according to presence or absence of acute myocyte necrosis and then determined the underlying mechanisms of cardiac injury., Results: Of the 40 hearts examined, 14 (35%) had evidence of myocyte necrosis, predominantly of the left ventricle. Compared with subjects without necrosis, subjects with necrosis tended to be female, have chronic kidney disease, and have shorter symptom onset to admission. The incidence of severe coronary artery disease (ie, >75% cross-sectional narrowing) was not significantly different between those with and without necrosis. Three of 14 (21.4%) subjects with myocyte necrosis showed evidence of acute myocardial infarction, defined as ≥1 cm 2 area of necrosis, whereas 11 of 14 (78.6%) showed evidence of focal (>20 necrotic myocytes with an area of ≥0.05 mm 2 but <1 cm 2 ) myocyte necrosis. Cardiac thrombi were present in 11 of 14 (78.6%) cases with necrosis, with 2 of 14 (14.2%) having epicardial coronary artery thrombi, whereas 9 of 14 (64.3%) had microthrombi in myocardial capillaries, arterioles, and small muscular arteries. We compared cardiac microthrombi from COVID-19-positive autopsy cases to intramyocardial thromboemboli from COVID-19 cases as well as to aspirated thrombi obtained during primary percutaneous coronary intervention from uninfected and COVID-19-infected patients presenting with ST-segment-elevation myocardial infarction. Microthrombi had significantly greater fibrin and terminal complement C5b-9 immunostaining compared with intramyocardial thromboemboli from COVID-19-negative subjects and with aspirated thrombi. There were no significant differences between the constituents of thrombi aspirated from COVID-19-positive and -negative patients with ST-segment-elevation myocardial infarction., Conclusions: The most common pathological cause of myocyte necrosis was microthrombi. Microthrombi were different in composition from intramyocardial thromboemboli from COVID-19-negative subjects and from coronary thrombi retrieved from COVID-19-positive and -negative patients with ST-segment-elevation myocardial infarction. Tailored antithrombotic strategies may be useful to counteract the cardiac effects of COVID-19 infection.

Since its outbreak in China at the end of 2019, the new coronavirus disease (COVID-19) was characterized by both easy spreading and high mortality. The latter proved to be way more elevated in the North of Italy -with a peak of 18.4% in region Lombardia and even 31% in the city of Bergamo and surrounding county- than in the rest of the world. In an attempt to conceptualize the reasons for such a dramatic situation, four key elements have been identified: COVID-19 itself, old age, lung disease, and heart failure. Their harmful combination has been named "The deadly quartet". The underlying risk factors, among which a lot of them are distinctive features of the population in northern Italy, have been summarized as "unmodifiable", "partially modifiable", and "modifiable", for the sake of clarity. Up-to-date scientific evidence in this field has been described in the form of a narrative and easy-to-read review., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Purpose: Vertebral fractures (VFs) were described in elderly patients with heart failure (HF) whereas their prevalence and determinants in younger HF patients are still unknown. This study aimed at assessing whether secondary hyperparathyroidism (SHPT) may influence the risk of VFs in middle-aged patients with HF., Methods: 84 patients (44 males, median age 48.5 years, range 43-65) with HF were prospectively evaluated at the baseline and after 36-month follow-up for bone mineral density (BMD) and VFs by quantitative morphometry on chest X-rays. Serum PTH, calcium, 25-hydroxyvitamin D and 24-h-urinary calcium were evaluated at the baseline and every 6-12 months during the study period., Results: At baseline, SHPT, hypovitaminosis D and VFs were found in 43 patients (51.2%), 73 patients (86.9%) and 29 patients (34.5%), respectively. SHPT was associated with VFs at baseline [inverse probability-weighted (ipw) odds ratio (OR) 12.2, p < 0.001]. Patients were treated with vitamin D3 alone (56%), vitamin D3 plus calcium carbonate (21.4%), calcitriol alone (4.8%), bisphosphonates plus vitamin D3 (8.3%) or a combination of bisphosphonates, vitamin D3 and calcium carbonate (9.5%). At the end of follow-up, hypovitaminosis D was corrected in all patients, whereas 19/84 patients (22.6%) had persistent SHPT. During the follow-up, 16 patients developed incident VFs which resulted to be associated with baseline SHPT (ipw OR 55.7, p < 0.001), even after adjusting from BMD change from baseline to follow-up (ipw OR 46.4, p < 0.001)., Conclusions: This study provides a first evidence that SHPT may be a risk factor for VFs in middle-aged patients with HF.

Background: . The electrocardiographic (ECG) changes which may occur during hospitalization for COVID-19 have not yet been comprehensively assessed., Patients and Methods: . We examined 50 patients admitted to hospital with proven COVID-19 pneumonia. At entry, all patients underwent a detailed clinical examination, 12-lead ECG, laboratory tests and arterial blood gas test. ECG was also recorded at discharge and in case of worsening clinical conditions., Results: . Mean age of patients was 64 years and 72% were men. At baseline, 30% of patients had ST-T abnormalities, and 33% had left ventricular hypertrophy. During hospitalization, 26% of patients developed new ECG abnormalities which included atrial fibrillation, ST-T changes, tachy-brady syndrome, and changes consistent with acute pericarditis. One patient was transferred to intensive care unit for massive pulmonary embolism with right bundle branch block, and another for non-ST segment elevation myocardial infarction. Patients free of ECG changes during hospitalization were more likely to be treated with antiretrovirals (68% vs 15%, p = 0.001) and hydroxychloroquine (89% vs 62%, p = 0.026) versus those who developed ECG abnormalities after admission. Most measurable ECG features at discharge did not show significant changes from baseline (all p>0.05) except for a slightly decrease in Cornell voltages (13±6 vs 11±5 mm; p = 0.0001) and a modest increase in the PR interval. The majority (54%) of patients with ECG abnormalities had 2 prior consecutive negative nasopharyngeal swabs. ECG abnormalities were first detected after an average of about 30 days from symptoms' onset (range 12-51 days)., Conclusions: . ECG abnormalities during hospitalization for COVID-19 pneumonia reflect a wide spectrum of cardiovascular complications, exhibit a late onset, do not progress in parallel with pulmonary abnormalities and may occur after negative nasopharyngeal swabs., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 European Federation of Internal Medicine.
