- Abstract
The prolongation of the QTc interval on the electrocardiogram is known to be associated with an increased risk of developing life–threatening ventricular arrhythmias such as torsades de pointes (TdP). QTc values exceeding 500 ms can double or even triple the risk of TdP. Many drugs, including amiodarone and some SSRI antidepressants like paroxetine, can prolong the QTc interval. A 57–year–old patient experienced cardiac arrest during an overnight Holter recording prescribed to exclude brady–tachy syndrome in the presence of persistent atrial fibrillation. ECG ambulatory monitoring revealed significant bradycardia with the onset of idioventricular rhythm, followed by TdP triggered by premature ventricular contractions, subsequently degenerating into ventricular fibrillation. The patient was resuscitated by family members and later by emergency medical personnel using 3 DC shocks, leading to the restoration of spontaneous circulation. The patient was transferred to the cardiology intensive care unit where a coronary angiography showed normal results. Blood tests indicated low potassium levels (3.3 mEq/L), with a moderately reduced left ventricular ejection fraction at 45%. The patient was discharged after ICD implantation and during the diagnostic follow–up the genetic testings for long QT syndrome were negative, but showed a mutation of the LMNA lamin A/C gene. During the two months previous to hospital admission, the patient had complained of fatigue in the presence of atrial fibrillation with a low ventricular response. Nonetheless, she had been prescribed oral amiodarone to optimize the chances of successful electrical cardioversion, in combination with paroxetine that the patient was already taking at home. The combination of these two drugs and the patient‘s idiopathic bradycardia contributed to a marked prolongation of the QT interval, leading to TdP degenerated into ventricular fibrillation. This case, notable for the prolonged recording of ventricular fibrillation and subsequent resuscitation chest compressions during a Holter monitoring, suggests caution in the use of antiarrhythmic drugs unless strongly indicated in the presence of potentially ominous drug interactions. It is encouraging to note how the widespread adoption of cardiopulmonary resuscitation culture has enabled individuals who might not have otherwise received medical attention to be effectively resuscitated.

- Abstract
We describe the case of a 68–year–old patient who presented to the Emergency Department following an unwitnessed syncopal episode with slow recovery of consciousness. On admission, the patient had dyspnoea together with physical signs of pulmonary congestion. Cardiac ultrasound showed severe left ventricular dysfunction with an ejection fraction of 30%, and apical and paraapical akinesis. The admission electrocardiogram showed sinus tachycardia and diffuse repolarization abnormalities, hs TnI was elevated and BNP vl blood gas analysis were unremarkable. During observation in the Emergency Department, the patient experienced epileptic seizure, promptly resolved by intravenous Midazolam. Contrast–enhanced chest CT ruled out aortic dissection disclosing a clinically irrelevant subsegmental pulmonary embolism. A non–contrast CT scan of the brain yielded negative results. In consideration of the atypical clinical presentation and scattered evidence of an acute coronary syndrome, the patient was admitted to our Cardiac Intensive Care Unit (CICU) for additional diagnostic workup delaying coronary angiography in the presence of stable TnI elevation. Three hours after admission the patient continued showing altered consciousness and a subsequent brain CT was performed, demonstrating an intraparenchymal hemorrhagic spreading. Repeat ECGs showed precordial T wave inversion and prolongation of the QT interval. These data, together with LV apical dysfunction, raised the suspicion of Takotsubo syndrome secondary to an acute cerebrovascular event. During the hospital stay, recovery of consciousness, spontaneous absorption of the cerebral hemorrhagic spread and complete recovery of left ventricular function at repeat cardiac ultrasound examinations were observed, confirming the almost unequivocal diagnosis of Takotsubo syndrome. The patient was discharged uneventfully and was scheduled for an outpatient coronary CT scan. This case underscores the crucial importance of a thorough clinical assessment in the management of complex patients in the presence of nonunivocal clinical signs and misleading blood test and imaging data. Moreover, Takotsubo syndrome is a protean clinical entity that can precede the index event as in our patient, i.e. cerebral hemorrhage. Misclassification of these patients as having an acute coronary syndrome could have led to the initiation of antithrombotic therapy, with potential fatal outcomes for the patient.

- Abstract
OBJECTIVE: To understand whether patients with post-ischemic dilated cardiomyopathy and myocardial viability (MV) could benefit from cardiac resynchronization therapy (CRT) in terms of clinical, echocardiographic and neuro- hormonal parameters compared to patients without MV. METHODS: One hundred and four consecutive patients were enrolled in a prospective observational cohort study. Using dobutamine stress echocardiography, 2 groups were identified: group A of 51 patients with MV and group B of 53 patients without MV. All patients were implanted with biventricular pacing devices combined with an internal cardioverter-defibrillator. Clinical, echocardiographic and neuro-hormonal parameters were evaluated at baseline and at six month follow-up. Analysis of variance for repeated measures on each variable suggestive of remodeling was performed. We considered responder every patient with: decrease of > 15% in left ventricular volumes and/or improvement in left ventricular ejection fraction of > 5% in addition to NYHA class improvement. RESULTS: All the variables improved in both groups (time effect). Comparing the two groups (group effect), the following variables were significantly better in group A: N-terminal pro-B-type natriuretic peptide (p=0.02), NYHA class (p=0.003), reverse remodeling (RR) (p=0.007), dP/dt (p=0.005), left ventricular ejection fraction (p=0.009), 3rd sound (p=0.01), and left ventricular end-systolic volume after the first week (p=0.035). RR occurred at the first week after CRT only in Group A and was maintained for all the time of this study. The maximum difference of the decrease of left ventricular volumes between the two groups occurred after the first week (p<0.001). CONCLUSION: Patients with MV responded better than patients without MV with a significant improvement after the first week from CRT. [ABSTRACT FROM AUTHOR]

- Abstract
The products of c-fos and c-jun proto-oncogenes form the heterodimeric complex AP-1 (activator protein 1), which play an important part in the control of bone cell proliferation and differentiation and in the development of bone tumours. We examined the expression of c-fos and c-jun in a series of 52 primary skeletal neoplasms, using an immunohistochemical method on formalin-fixed, paraffin-embedded sections. The expression of c-fos and c-jun was restricted to bone-forming lesions, while cartilaginous tumours were devoid of immunoreactivity. In benign osteoblastic lesions moderate c-fos and c-jun expression was found in 2 cases (18.1%). The highest levels of c-fos and c-jun expression were detected in high-grade central osteosarcomas (7 of 15 cases with moderate/diffuse expression) while 1 telangiectatic osteosarcoma, 2 low-grade central osteosarcomas, 1 low-grade periosteal osteosarcoma and 7 low-grade parosteal osteosarcomas were either negative or had low expression. The high-grade component of a dedifferentiated parosteal osteosarcoma showed diffuse immunoreactivity for both oncoproteins. Comparison of c-fos and c-jun expression by histological grade showed that high-grade osteosarcomas had a significantly higher expression of both oncoproteins than did low-grade osteosarcomas (P = 0.01, Fisher's exact test). Thus, c-fos and c-jun overexpression may be implicated in the development of high-grade osteosarcomas, but they appear to have little or no relevance for the development of low-grade osteosarcomas and cartilaginous skeletal neoplasms.

- Abstract
Idiopathic dilatation of the pulmonary artery (IDPA) is an uncommon anomaly occurring in 0.6% of patients with congenital heart disease. IDPA is characterized by the enlargement of the main pulmonary artery with or without dilatation of the right and left pulmonary arteries. We describe 2D and Real-Time 3D Echocardiography findings in a young adult with IDPA. To the best of our knowledge this is the first case reporting all echocardiographic findings diagnostic for IDPA.

The product of the human retinoblastoma gene (pRb) is a nuclear phosphoprotein that is thought to function as a tumor suppressor. Heterogeneous expression of the Rb gene product contributes to the genesis of a diverse group of human neoplasma such as breast, prostate, small cell lung, bladder carcinomas and leukemia. The clinical importance of Rb function demands a reproducible Rb immunohistochemical assay to distinguish Rb+ from Rb- tumor cells. We report an immunohistochemical study to detect Rb protein in a series of 50 invasive breast cancers. Our results support the hypothesis that the Rb gene functions as both a cell growth factor and a tumor suppressor.

Cingulin is a 140-kd protein localized on the cytoplasmic face of avian tight junctions. The expression of cingulin in human normal and neoplastic colonic tissue has been investigated with an antiserum against chicken cingulin. Human cingulin shares its apparent molecular mass and localization with avian cingulin. In normal colonic epithelium, villous adenomas, and differentiated adenocarcinomas, cingulin staining is observed in the junctional region of the polarized cells lining the surface, the crypts, and the glandular lumina. In poorly differentiated adenocarcinomas, labeling also is observed at the interface between cancer tissue and stroma, or in clumps of malignant cells, forming a pattern that highlights the presence of small, compressed lumina. The cingulin content of four adenocarcinomas, estimated by immunoblotting and densitometry, was higher than that of the normal tissue (150% to 230%). Cingulin was detected in a metastasis from a colon adenocarcinoma but not in nonepithelial tissues and neoplasias, suggesting that cingulin may be a useful marker in the characterization of colonic and probably other epithelial neoplasias.

Abstract Background Cardiac allograft vasculopathy (CAV) is a major late complication in cardiac transplant recipients and has a relevant impact on outcome of these patients. Aims of this study: to compare, in cardiac transplant recipients patients, the diagnostic value of pressure/volume relationship (ESPVR) during dobutamine stress echocardiography (DSE) for coronary artery disease, assessed by Multislice Computed Tomography (MSCT), and by coronary angiography (CA). We also analyzed any possible relationship between ESPVR and the Health Related Quality of Life of the patients (HRQoL), evaluated by SF–36 questionnaire. Methods 25 consecutive patients underwent DSE within 24 hours after MSCT coronary angiogram and then they underwent CA. The HRQoL questionnaire was administered to the patients in the settings of DSE. They were followed-up for 6 months. Results DSE has a sensitivity in detecting CAV of 67%, specificity of 95%, positive predictive value of 67% and negative predictive value of 95%; DSE with ESPVR has a sensitivity of 100%, specificity of 95%, positive predictive value of 75%, negative predictive value of 100%; MSCT has a sensitivity of 100%; specificity of 82%; positive predictive value of 43%; negative predictive value of 100%. Htx recipients with a flat-biphasic ESPVR, although asymptomatic, perceived a worst HRQoL compared with the up-sloping ESPVR population, and this is statistically significant for the general health (p 0.0004), the vitality (p 0.0013) and the mental health (p 0.021) SF-36 subscale. Conclusions Evaluation with DSE and ESPVR is accurate in the clinical control of heart transplant recipients reserving invasive evaluation only for patients with abnormal contractility indexes.

Abstract Objectives This study was designed to describe Doppler-echocardiography values of Carpentier-Edwards Perimount Standard (CEPS) and Carpentier-Edwards Perimount Magna (CEPM) aortic prosthetic valves, evaluated by a single, experienced echo-laboratory, early in the postoperative phase. Methods Three-hundred-seventy-seven consecutive patients, who had had a CEPS or a CEPM implanted in our Hospital due to aortic stenosis and/or insufficiency, underwent baseline Doppler echocardiography evaluation within 7 days after surgery. Hemodynamic performances of CEPS and CEPM were accurately described, evaluating flow-dependent (transprosthetic velocities and gradients) and flow-independent (effective orifice area, indexed effective orifice area and Doppler velocity index) Doppler-echocardiography parameters. Results Out of the 377 patients 48.8% were men (n = 184), mean age was 74.63 ± 6.77 years, mean BSA was 1.78 ± 0.18 m2, mean ejection fraction was 57.78 ± 8%. Two-hundred and sixty two CEPS and 115 CEPM were implanted. Comparing size-by-size CEPS with CEPM, both prostheses showed a good hemodynamic profile, with fairly similar values of pressure gradients (PGmax and mean, in mmHg, = 37,18 ± 11.57 and 20.81 ± 7.44 in CEPS n°19 compared to 32,47 ± 7,76 and 17,67 ± 4.63 in CEPM n°19 and progressively lower in higher sized prostheses, having PGmax and mean 15 ± 3,16 and 9.15 ± 1,29 in CEPS n°29 compared to 15,67 ± 1,53 and 9 ± 1 in CEPM n°29) and EOAi (being 0,65 ± 0,33 cm²/m² in CEPS n°19 compared to 0,77 ± 0,29 cm²/m² in CEPM n°19 and progressively higher in higher sized prostheses, being 1,28 ± 0,59 cm²/m² in CEPS n°29 compared to 1,07 ± 0,18 cm²/m² in CEPM n°29), the latter resulting, however, basically less flow obstructive. Conclusions Our data confirm the good hemodynamic performance of both aortic bioprostheses and the more favourable hemodynamic profile of CEPM compared to CEPS, pointing out the need to perform routinely an accurate baseline Doppler-echocardiography evaluation early after surgery to allow an adequate interpretation of data at follow-up.

- Abstract
In a 72-year-old male patient an acute coronary syndrome (ACS) was complicated by left ventricular aneurysm and severe mitral regurgitation. Two-dimensional echocardiography failed in detecting mechanism of mitral regurgitation. Transthoracic three dimensional echocardiography allowed us to obtain a better visualization of the relationship between papillary muscles, ventricular walls and mitral leaflets and dynamic systolic displacement of the posterior papillary muscle associated with restriction of both leaflets with greater apical tethering of anterior leaflet (A3-A2 scallops). Echocardiography performed after cardiac surgery revealed that ventricular reshaping after posterior papillary muscle realignment allowed the mitral regurgitation resolution. [ABSTRACT FROM AUTHOR]

- Abstract
Extracellular vesicles (EVs) are membrane-enclosed bio-nanoparticles secreted by cells and naturally evolved to transport various bioactive molecules between cells and even organisms. These cellular objects are considered one of the most promising bio-nanovehicles for the delivery of native and exogenous molecular cargo. However, many challenges with state-of-the-art EV-based candidates as drug carriers still exist, including issues with scalability, batch-to-batch reproducibility, and cost-sustainability of the final therapeutic formulation. Microalgal extracellular vesicles, which we named nanoalgosomes, are naturally released by various microalgal species. Here, we evaluate the innate biological properties of nanoalgosomes derived from cultures of the marine microalgae Tetraselmis chuii, using an optimized manufacturing protocol. Our investigation of nanoalgosome biocompatibility in preclinical models includes toxicological analyses, using the invertebrate model organism Caenorhabditis elegans, hematological and immunological evaluations ex vivo and in mice. We evaluate nanoalgosome cellular uptake mechanisms in C. elegans at cellular and subcellular levels, and study their biodistribution in mice with accurate space-time resolution. Further examination highlights the antioxidant and anti-inflammatory bioactivities of nanoalgosomes. This holistic approach to nanoalgosome functional characterization demonstrates that they are biocompatible and innate bioactive effectors with unique bone tropism. These findings suggest that nanoalgosomes have significant potential for future therapeutic applications., (© 2024. The Author(s).)

- Abstract
Wilson disease (WD) is caused by mutations in the ATP7B gene that encodes a copper (Cu) transporting ATPase whose trafficking from the Golgi to endo-lysosomal compartments drives sequestration of excess Cu and its further excretion from hepatocytes into the bile. Loss of ATP7B function leads to toxic Cu overload in the liver and subsequently in the brain, causing fatal hepatic and neurological abnormalities. The limitations of existing WD therapies call for the development of new therapeutic approaches, which require an amenable animal model system for screening and validation of drugs and molecular targets. To achieve this objective, we generated a mutant Caenorhabditis elegans strain with a substitution of a conserved histidine (H828Q) in the ATP7B ortholog cua-1 corresponding to the most common ATP7B variant (H1069Q) that causes WD. cua-1 mutant animals exhibited very poor resistance to Cu compared to the wild-type strain. This manifested in a strong delay in larval development, a shorter lifespan, impaired motility, oxidative stress pathway activation, and mitochondrial damage. In addition, morphological analysis revealed several neuronal abnormalities in cua-1 mutant animals exposed to Cu. Further investigation suggested that mutant CUA-1 is retained and degraded in the endoplasmic reticulum, similarly to human ATP7B-H1069Q. As a consequence, the mutant protein does not allow animals to counteract Cu toxicity. Notably, pharmacological correctors of ATP7B-H1069Q reduced Cu toxicity in cua-1 mutants indicating that similar pathogenic molecular pathways might be activated by the H/Q substitution and, therefore, targeted for rescue of ATP7B/CUA-1 function. Taken together, our findings suggest that the newly generated cua-1 mutant strain represents an excellent model for Cu toxicity studies in WD., (© 2023 The Authors.

- Abstract
According to the amyloid hypothesis, in the early phases of Alzheimer's disease (AD), small soluble prefibrillar aggregates of the amyloid β-peptide (Aβ) interact with neuronal membranes, causing neural impairment. Such highly reactive and toxic species form spontaneously and transiently in the amyloid building pathway. A therapeutic strategy consists of the recruitment of these intermediates, thus preventing aberrant interaction with membrane components (lipids and receptors), which in turn may trigger a cascade of cellular disequilibria. Milk α
s1 -Casein is an intrinsically disordered protein that is able to inhibit Aβ amyloid aggregation in vitro , by sequestering transient species. In order to test αs1 -Casein as an inhibitor for the treatment of AD, it needs to be delivered in the place of action. Here, we demonstrate the use of large unilamellar vesicles (LUVs) as suitable nanocarriers for αs1 -Casein. Proteo-LUVs were prepared and characterized by different biophysical techniques, such as multiangle light scattering, atomic force imaging, and small-angle X-ray scattering; αs1 -Casein loading was quantified by a fluorescence assay. We demonstrated on a C. elegans AD model the effectiveness of the proposed delivery strategy in vivo . Proteo-LUVs allow efficient administration of the protein, exerting a positive functional readout at very low doses while avoiding the intrinsic toxicity of αs1 -Casein. Proteo-LUVs of αs1 -Casein represent an effective proof of concept for the exploitation of partially disordered proteins as a therapeutic strategy in mild AD conditions.- Published

- Abstract
Background: The Italian Society of Echography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand the volumes of activity, modalities and stressors used during stress echocardiography (SE) in Italy., Methods: We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved through an electronic survey based on a structured questionnaire, uploaded on the SIECVI website., Results: Data were obtained from 228 echocardiographic laboratories, and SE examinations were performed in 179 centers (80.6%): 87 centers (47.5%) were in the northern regions of Italy, 33 centers (18.4%) were in the central regions, and 61 (34.1%) in the southern regions. We annotated a total of 4057 SE. We divided the SE centers into three groups, according to the numbers of SE performed: <10 SE (low-volume activity, 40 centers), between 10 and 39 SE (moderate volume activity, 102 centers) and ≥40 SE (high volume activity, 37 centers). Dipyridamole was used in 139 centers (77.6%); exercise in 120 centers (67.0%); dobutamine in 153 centers (85.4%); pacing in 37 centers (21.1%); and adenosine in 7 centers (4.0%). We found a significant difference between the stressors used and volume of activity of the centers, with a progressive increase in the prevalence of number of stressors from low to high volume activity ( P = 0.033). The traditional evaluation of regional wall motion of the left ventricle was performed in all centers, with combined assessment of coronary flow velocity reserve (CFVR) in 90 centers (50.3%): there was a significant difference in the centers with different volume of SE activity: the incidence of analysis of CFVR was significantly higher in high volume centers compared to low - moderate - volume (32.5%, 41.0% and 73.0%, respectively, P < 0.001). The lung ultrasound (LUS) was assessed in 67 centers (37.4%). Furthermore for LUS, we found a significant difference in the centers with different volume of SE activity: significantly higher in high volume centers compared to low - moderate - volume (25.0%, 35.3% and 56.8%, respectively, P < 0.001)., Conclusions: This nationwide survey demonstrated that SE was significantly widespread and practiced throughout Italy. In addition to the traditional indication to coronary artery disease based on regional wall motion analysis, other indications are emerging with an increase in the use of LUS and CFVR, especially in high-volume centers., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Cardiovascular Echography.)

- Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) have gained increasing interest in nanomedicine, but most of those that have entered the clinical trials have been withdrawn due to toxicity concerns. Therefore, there is an urgent need to design low-risk and biocompatible SPION formulations. In this work, we present an original safe-by-design nanoplatform made of silica nanoparticles loaded with SPIONs and decorated with polydopamine (SPIONs@SiO2-PDA) and the study of its biocompatibility performance by an ad hoc thorough in vitro to in vivo nanotoxicological methodology. The results indicate that the SPIONs@SiO
2 -PDA have excellent colloidal stability in serum-supplemented culture media, even after long-term (24 h) exposure, showing no cytotoxic or genotoxic effects in vitro and ex vivo. Physiological responses, evaluated in vivo using Caenorhabditis elegans as the animal model, showed no impact on fertility and embryonic viability, induction of an oxidative stress response, and a mild impact on animal locomotion. These tests indicate that the synergistic combination of the silica matrix and PDA coating we developed effectively protects the SPIONs, providing enhanced colloidal stability and excellent biocompatibility.- Published

- Abstract
Background: The Italian Society of Echocardiography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand better how different echocardiographic modalities are used and accessed in Italy., Methods: We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved via an electronic survey based on a structured questionnaire, uploaded on the SIECVI website., Results: Data were obtained from 228 echocardiographic laboratories: 112 centers (49%) in the northern, 43 centers (19%) in the central, and 73 (32%) in the southern regions. During the month of observation, we collected 101,050 transthoracic echocardiography (TTE) examinations performed in all centers. As concern other modalities there were performed 5497 transesophageal echocardiography (TEE) examinations in 161/228 centers (71%); 4057 stress echocardiography (SE) examinations in 179/228 centers (79%); and examinations with ultrasound contrast agents (UCAs) in 151/228 centers (66%). We did not find significant regional variations between the different modalities. The usage of picture archiving and communication system (PACS) was significantly higher in the northern (84%) versus central (49%) and southern (45%) centers ( P < 0.001). Lung ultrasound (LUS) was performed in 154 centers (66%), without difference between cardiology and noncardiology centers. The evaluation of left ventricular (LV) ejection fraction was evaluated mainly using the qualitative method in 223 centers (94%), occasionally with the Simpson method in 193 centers (85%), and with selective use of the three-dimensional (3D) method in only 23 centers (10%). 3D TTE was present in 137 centers (70%), and 3D TEE in all centers where TEE was done (71%). The assessment of LV diastolic function was done routinely in 80% of the centers. Right ventricular function was evaluated using tricuspid annular plane systolic excursion in all centers, using tricuspid valve annular systolic velocity by tissue Doppler imaging in 53% of the centers, and using fractional area change in 33% of the centers. When we divided into cardiology (179, 78%) and noncardiology (49, 22%) centers, we found significant differences in the SE (93% vs. 26%, P < 0.001), TEE (85% vs. 18%), UCA (67% vs. 43%, P < 0001), and STE (87% vs. 20%, P < 0.001). The incidence of LUS evaluation was similar between the cardiology and noncardiology centers (69% vs. 61%, P = NS)., Conclusions: This nationwide survey demonstrated that digital infrastructures and advanced echocardiography modalities, such as 3D and STE, are widely available in Italy with a notable diffuse uptake of LUS in the core TTE examination, a suboptimal diffusion of PACS recording, and conservative use of UCA, 3D, and strain. There are significant differences between northern and central-southern regions and echocardiographic laboratories that pertain to the cardiac unit. This inhomogeneous distribution of technology represents one of the main issues that must be solved to standardize the practice of echocardiography., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Cardiovascular Echography.)

- Abstract
Background: The pharmacological effects of cocaine have been associated with different types of cardiac dysrhythmias and with Brugada pattern on the ECG, but currently only type 1 pattern has been described. We report a case of a transient Brugada type 2 pattern in a young cocaine abuser., Method: We report the clinical presentation of a 32-year-old male with a history of cocaine abuse., Result: The treatment and the resolution of the acute phase have been described; moreover we discuss the pathophysiology of the Brugada phenocopy in this specificclinical setting., Conclusion: The clinical impact of our case report underscores the necessity of prompt physician awareness of any ECG abnormality besides myocardial infarction in patients with cocaine abuse, such as any Brugada pattern, which could lead to ominous ventricular arrhythmias., Competing Interests: None., (AJCD Copyright © 2020.)
