Higher Incidence of Cancer Therapy-Related Cardiac Dysfunction in the COVID-19 Era: A Single Cardio-Oncology Center Experience
2023
Aim: COVID-19 pandemic had a big impact on our life, it has revolutionized the practice of cardiology and the organization of hospital and outpatient activities. Thus the aim of our study was to assess the impact of the COVID-19 pandemic on the development of cancer therapy-related cardiac dysfunction (CTRCD). Methods and results: A single center retrospective study was carried out evaluating 96 cancer patients treated with anthracyclines and admitted to our Cardio-Oncology unit from June to August 2019 and 60 patients from June to August 2021. The incidence of CTRCD was assessed performing an echocardiogram at the time of the enrollment. We found a significantly higher incidence of CTRCD i…
Machine learning classification for COVID19 patients performed on small datasets of CT scans.
2022
In this work we evaluated the possibility of carrying out classifications of the outcome of patients with COVID19 disease through machine learning (ML) techniques working on small datasets of computed tomography (CT) images. In fact, one of the most common problems for medical artificial intelligence (AI) applications is the limited availability of annotated clinical data for model training. In the framework of the artificial intelligence in medicine (AIM) project funded by INFN, we analyzed datasets of CT scans of 79 subjects combined with clinical data containing information relating to positive outcome (no need for intensive care) or poor prognosis (admission into intensive care unit and…

Evaluation of Cardiac Volumetric and Functional Parameters
2012
The milestone definition of “Cardiac Function” has to be attributed to William Harvey, the discoverer of the circulation, who in 1628 stated: “The movement of the blood is constantly in a circle, and is brought about by the beat of the heart” [1, 2]. From a modern point of view, the main function of the heart is the delivery of oxygen to metabolizing tissues. Since oxygen delivery is dependent on (1) the oxygen-carrying capacity of blood, (2) the flow output from the heart, and (3) regional distribution of flow, then the heart is nowadays regarded as a pump with the function of supplying flow in blood vessels [2].
Integrated non-invasive approach to atherosclerosis with cardiac CT and carotid ultrasound in patients with suspected coronary artery disease
2017
The aim of the study was to compare the atherosclerotic disease in the coronary and carotid arteries in patients who underwent non-invasive imaging for suspected stable coronary artery disease (CAD). 107 patients (64 men, age 59 ± 12) with atypical chest pain underwent cardiac CT (CCT) and carotid ultrasound (US) on the same day. Severity (obstructive or not-obstructive disease), location, shape, and composition of atherosclerotic plaques in the two districts were evaluated. Patients presented normal coronary arteries in 36 % (n = 38), not-obstructive CAD in 36 % (n = 39), and obstructive CAD in 28 % (n = 30), while had normal carotid arteries in 53 % (n = 57), not-obstructive disease in 44…
Minimization of childhood maltreatment is common and consequential: results from a large, multinational sample using the childhood trauma questionnai…
2016
Childhood maltreatment has diverse, lifelong impact on morbidity and mortality. The Childhood Trauma Questionnaire (CTQ) is one of the most commonly used scales to assess and quantify these experiences and their impact. Curiously, despite very widespread use of the CTQ, scores on its Minimization-Denial (MD) subscale-originally designed to assess a positive response bias-are rarely reported. Hence, little is known about this measure. If response biases are either common or consequential, current practices of ignoring the MD scale deserve revision. Therewith, we designed a study to investigate 3 aspects of minimization, as defined by the CTQ's MD scale: 1) its prevalence; 2) its latent struc…
Preliminary investigations on the occurrence of Citrus Tristeza Virus (CTV)in central-western Sicilian orchards and on the mycorrhizal status in citr…
2013
In the last decade, since the first outbreak of Citrus tristeza virus (CTV) in the province of Catania (2002), several new CTV foci were found in Sicily. In order to determine CTV occurrence in centra-lwestern Sicily, identify and characterize viral strains and verify the mycorrhizal status of citrange [Citrus sinensis (L.) Osb. × Poncirus trifoliate (L.) Raf.]. one of the most utilized tollerant rootstock, an epidemiological survey was carried out in 2011. Symptomless samples from citrus groves from different Sicilian provinces (Agrigento, Palermo, Trapani, Caltanissetta) were collected and submitted to serological assay. Only samples from Agrigento and Palermo provinces were ELISA-positiv…
