Effect of Plasma Unit Weight and Donor Sex on Post-Donation Citrate Level: An Experimental Study on Plasmapheresis Donors.

Introduction: Plasmapheresis donation is considered safe and well tolerated, although long-term effects need to be clarified. The volumes of anticoagulant (ACD-A) used are variable and depend primarily on hematocrit (HCT), total blood processed, amount of plasma collected, and donor characteristics. To elucidate the effect of the plasma unit weight setting on plasmapheresis efficiency and ACD-A distribution, we enrolled male donors undergoing a controlled apheresis process donating 700 g and 720 g in two different sessions. In parallel, we investigated a possible effect of sex, recruiting women donating 700 g of plasma. Methods: The study was conducted on men donating 720 g and (12 months later) 700 g of plasma, and on women donating 700 g of plasma. The main outcomes were pre-/post-donation delta (Δ) citrate concentration in donor plasma and ACD-A reinfused to the donor. Information concerning the annual check-up and the procedure was also collected. Intergroup comparisons (men donating 720 g vs. men donating 700 g and men vs. women both donating 700 g) and intragroup associations with donor and procedural characteristics were reported. Results: With the procedure set at 720 g, the machine processed around 44 mL more whole blood to collect 20 g more plasma, and 720 g donors received around 12 mL more anticoagulant than 700 g donors. Accordingly, Δ citrate concentration was 1.5 times higher (12 µm), with a greater variability observed for 720 g donations. Citrate concentration in the plasma unit was lower in the 720 g group, although not significantly. Comparing outcomes between women and men donating 700 g, we observed higher (and highly variable) Δ citrate and reinfused ACD-A in women, accompanied by lower anticoagulant levels in the unit. Increased Δ citrate is inversely associated with HCT and age in men and with HCT and triglycerides in women. Reinfused ACD-A correlates with HCT in women but not in men. Conclusion: Unit weight setting and sex influence an ACD-A shift from the estimated values toward an increased reinfusion to donor. In parallel, we observed an impact of age and sex on post-donation citrate metabolism. Altogether, these elements should be taken into account for the development of tailored approaches aimed at maintaining similar safety profiles for all donors using different plasmapheresis settings.

The Italian Society of Cardiology and Working Group on Telecardiology and Informatics 2023 updated position paper on telemedicine and artificial intelligence in cardiovascular disease.

In 2015, the Italian Society of Cardiology and its Working Group on Telemedicine and Informatics issued a position paper on Telecardiology, resuming the most eminent evidence supporting the use of information and communication technology in principal areas of cardiovascular care, ranked by level of evidence. More than 5 years later and after the global shock inflicted by the SARS-CoV-2 pandemic, an update on the topic is warranted. Recent evidence and studies on principal areas of cardiovascular disease will be therefore reported and discussed, with particular focus on telemedicine for cardiovascular care in the COVID-19 context. Novel perspectives and opportunities disclosed by artificial intelligence and its applications in cardiovascular disease will also be discussed. Finally, modalities by which machine learning have realized remote patient monitoring and long-term care in recent years, mainly filtering critical clinical data requiring selective hospital admission, will be provided.

The impact of COVID-19 outbreak on the Transfusion Medicine Unit of a Northern Italy Hospital and Cancer Centre.

BACKGROUND AND OBJECTIVES: The first wave of coronavirus disease-2019 (COVID-19) dramatically affected the Transfusion Medicine Unit of the Azienda Unità Sanitari Locale - Istituto di Ricovero e Cura a Carattere Scientifico (AUSL-IRCCS) di Reggio Emilia, which faced a total rearrangement of the procedures for donors and patients. This study aims to assess the major implications of COVID-19 on our department, focusing on the blood transfusion chain and therapies, in order to support transfusion specialists in seeking efficient ways to face similar future emergencies. MATERIALS AND METHODS: This retrospective study compares our Transfusion Medicine Unit data collected between February and May 2020 with the same period in 2017-2019. Data on red blood cells and platelets donations, transfusions and clinical procedures were collected as aggregates from our internal electronic database. RESULTS: During the lockdown, donor centres were re-organized to reduce the risk of contagion and avoid unnecessary blood collection. Blood donations were re-scheduled to meet the decrease in elective surgery; consequently, plateletapheresis was implemented to supply the reduction of buffycoat-derived platelets. Transfusions significantly decreased together with orthopaedic and vascular surgery, while they were only marginally diminished for both cancer and onco-haematological patients. Reduced procedures for inpatients and outpatients were matched by remote medicine, addressing the need of a constant healthcare support for patients with chronic diseases. CONCLUSIONS: The described measures were adopted to avoid excessive blood collection and expiration, guarantee the safety of our ward (for both patients and staff) and supply the necessary transfusion therapies. These measures may support the development of appropriate risk management plans and safety procedures for other hospitals and transfusion services that have to face similar events.

[Italian Society of Cardiology (SIC) Position paper: Technical, instrumental and standards of interpretation for electrocardiography, ambulatory electrocardiographic and blood pressure monitoring in telemedicine]. / Position paper della Società Italiana di Cardiologia (SIC): Requisiti tecnici, strumentali e di refertazione per elettrocardiografia a riposo, monitoraggio elettrocardiografico ambulatoriale secondo Holter, monitoraggio ambulatoriale della pressione arteriosa in telemedicina.

The current COVID-19 pandemic has renewed interest in providing healthcare services based on the implementation of innovative technologies. Such strategy capillarizes the therapeutic opportunities for larger urban areas, mostly when people are living under extraordinarily difficult circumstances. Improving care delivery in cardiovascular diseases appears particularly feasible when telemedicine is pursued, especially with regard to baseline standard 12-lead electrocardiography, ambulatory electrocardiographic monitoring, and 24-hour ambulatory blood pressure monitoring. Nowadays, these first-line cardiovascular examinations are also available in health centers and pharmacies, and in recent months, there has been an increasing demand of such local services in the absence of specific rules and regulations regarding technical requirements and standards of interpretation that ensure a high quality clinical consultation.The purpose of this position paper is to provide critical requirements for the type/model of devices to be used, training dedicated to healthcare personnel, ensuring security of sensitive data, highlighting type of platforms to be used, as well as for maintaining high reporting quality and standards.

Comparison of Two Alternative Procedures to Obtain Packed Red Blood Cells for ß-Thalassemia Major Transfusion Therapy.

ß-thalassemia major (ßTM) patients require frequent blood transfusions, with consequences that span from allogenic reactions to iron overload. To minimize these effects, ßTM patients periodically receive leucodepleted packed red blood cells (P-RBCs) stored for maximum 14 days. The aim of this study was to compare two alternative routine procedures to prepare the optimal P-RBCs product, in order to identify differences in their content that may somehow affect patients' health and quality of life (QoL). In method 1, blood was leucodepleted and then separated to obtain P-RBCs, while in method 2 blood was separated and leucodepleted after removal of plasma and buffycoat. Forty blood donors were enrolled in two independent centers; couples of phenotypically matched whole blood units were pooled, divided in two identical bags and processed in parallel following the two methods. Biochemical properties, electrolytes and metabolic composition were tested after 2, 7 and 14 days of storage. Units prepared with both methods were confirmed to have all the requirements necessary for ßTM transfusion therapy. Nevertheless, RBCs count and Hb content were found to be higher in method-1, while P-RBCs obtained with method 2 contained less K+, iron and storage lesions markers. Based on these results, both methods should be tested in a clinical perspective study to determine a possible reduction of transfusion-related complications, improving the QoL of ßTM patients, which often need transfusions for the entire lifespan.

Impact of 2020 SARS-CoV-2 outbreak on telemedicine management of cardiovascular disease in Italy.

The Covid-19 pandemic affected large part of Italy since February 2020; we, therefore, aimed to assess the impact of 2020 SARS-CoV-2 outbreak on telemedicine management of cardiovascular disease (CVD) in Italy. We analyzed data from three telemedicine dispatch centers, one located in Genoa, serving private clients (pharmacies, general practitioners), one in Brescia, serving pharmacies, and one in Bari, serving regional public STEMI network and emergency medical service in Apulia (4 million inhabitants). Demographic data and principal electrocardiogram diagnosis were collected and analyzed. Records from the time interval March 1, 2020 and April 1, 2020 were compared with the corresponding period in 2019. The comparative analysis of data shows a 54% reduction of telemedicine electrocardiogram transmission in Genoa telemedicine center (from 364 to 166), 68% in Brescia (from 5.745 to 1.905), 24% in Bari (from 15.825 to 11.716); relative reduction according to electrocardiogram diagnosis was 38% for acute coronary syndrome, 40% for other acute CVD in Genoa center, 24% for acute coronary syndrome, and 38% for other acute CVD in Bari. Male/female ratio remained substantially unchanged. A dramatic reduction of telemedicine access for CVD was observed during Covid-19 outbreak in March 2020 in Italy. The reduction was substantially consistent for all electrocardiogram findings, ACS, other acute CVD and normal.

2019 Italian Society of Cardiology Census on telemedicine in cardiovascular disease: a report from the working group on telecardiology and informatics.

Background: The aim of this study was to assess by a census supported by the Italian Society of Cardiology (Società Italiana di Cardiologia, SIC) the present implementation of telemedicine in the field of cardiovascular disease in Italy. Methods: A dedicated questionnaire was sent by email to all the members of the SIC: data on telemedicine providers, service provided, reimbursement, funding and organisational solutions were collected and analysed. Results: Reported telemedicine activities were mostly stable and public hospital based, focused on acute cardiovascular disease and prehospital triage of suspected acute myocardial infarction (prehospital ECG, always interpreted by a cardiologist and not automatically reported by computerised algorithms). Private companies delivering telemedicine services in cardiology (ECGs, ambulatory ECG monitoring) were also present. In 16% of cases, ECGs were also delivered through pharmacies or general practitioners. ICD/CRT-D remote control was performed in 42% of cases, heart failure patient remote monitoring in 37% (21% vital parameters monitoring, 32% nurse telephone monitoring). Telemedicine service was public in 74% of cases, paid by the patient in 26%. About half of telemedicine service received no funding, 17% received State and/or European Union funding. Conclusions: Several telemedicine activities have been reported for the management of acute and chronic cardiovascular disease in Italy. The whole continuum of cardiovascular disease is covered by telemedicine solutions. A periodic census may be useful to assess the implementation of guidelines recommendations on telemedicine.

Telecardiology and its settings of application: An update.

Among the wide range of medical specialties in which telemedicine has been successfully applied, cardiology can be considered as one of the most important fields of application. Through the transmission of clinical data and the electrocardiogram, telecardiology allows access to a real-time assessment (teleconsultation) without any need to travel for both patient and cardiologist. This review discusses the impact of telecardiology in different clinical settings of application. Pre-hospital telecardiology has proved to be useful either in the clinical management of remote patients with acute coronary syndrome or in supporting the decision-making process of general practitioners. In the setting of in-hospital telecardiology, most of the applications refer to real-time echocardiography transmissions between rural small hospitals and tertiary care centres, particularly for the diagnosis or exclusion of congenital heart disease in newborns. Finally, many trials show that post-hospital telecardiology improves outcomes and reduces re-admissions or outpatient contacts in patients with heart failure, arrhythmias or implantable devices.

Electrocardiograms of Children and Adolescents Practicing Non-competitive Sports: Normal Limits and Abnormal Findings in a Large European Cohort Evaluated by Telecardiology.

OBJECTIVE: The objective of this study was to derive normal electrocardiographic values and to report the abnormal findings in a large contemporary European cohort of physically active children and young adolescents. METHODS: In a 3-month period, data derived from subjects aged between 3 and 14 years and referred to the Telecardiology Centre (Genoa, Italy) for electrocardiogram (ECG) evaluation as pre-participation screening for non-competitive sports were analyzed. RESULTS: A total of 2060 ECGs were recorded. Of those, 1962 did not show any morphological abnormality and were used to derive normality ranges for heart rate, PR interval, QRS duration, corrected QT interval, and voltage of R wave as measured in V1 according to age and sex. Findings and clinical implications of the 98 ECGs with abnormal findings were also reported. Abnormal ECG findings were not as uncommon as expected in this population, being manifest in about 5 % of subjects. However, major ECG anomalies (diffuse negative T-waves, pre-excitation) were present in just ten subjects (0.5 %). Lower mean heart rate values (from 90-100 bpm at 3 years of age to 80-85 bpm at 14 years of age) and lower rates of the prevalence of negative T-waves in the V3 lead (from 55-60 % at 3 years of age to 8-10 % at 14 years of age) were observed with increasing age. CONCLUSIONS: This is the first work reporting derived normal limits and abnormal ECG findings in a large contemporary European cohort of children and adolescents aged 3-14 years practicing non-competitive sports. Clear pathological alterations are extremely uncommon, deserving, when encountered, additional examinations. Even in a physically active population, the common features of an adult athlete's ECG are absent.

Innovations in telemedicine for cardiovascular care.

Cardiovascular disease is one of the main fields of application for telemedicine, with benefits in almost all areas in the continuum of cardiovascular disease. The greatest impact has been shown in the early diagnosis of cardiovascular disease, in second consultation, between non-cardiologist and cardiologist and between cardiologists, and in follow-up and secondary prevention of cardiovascular disease. At present, the main area of implementation for telemedicine in cardiovascular disease is represented by pre-hospital triage, with telemedicine electrocardiogram in acute myocardial infarction. Significant results have also been achieved in the second opinion consultation of pediatric subjects with congenital cardiovascular disease, home-monitoring and the management of patients affected by chronic heart failure or with an implanted device. However, there is significant room for further improvement in delivering telemedicine assistance even in 'very-remote' populations, such as detainees, patients in developing countries or in underdeveloped areas of developed countries.

Telemedicine for cardiovascular disease continuum: A position paper from the Italian Society of Cardiology Working Group on Telecardiology and Informatics.

Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. First data on implementation of telemedicine for the diagnosis and treatment of acute myocardial infarction date from more than 10 years ago. Telemedicine has a potential broad application to the cardiovascular disease continuum and in many branches of cardiology, at least including heart failure, ischemic heart disease and arrhythmias. Telemedicine might have an important role as part of a strategy for the delivery of effective health care for patients with cardiovascular disease. In this document the Working Group on Telecardiology and Informatics of the Italian Society of Cardiology intends to remark some key-points regarding potential benefit achievable with the implementation of telemedicine support in the continuum of cardiovascular disease.

Cardiac magnetic resonance imaging detects subclinical right ventricular impairment in systemic sclerosis.

OBJECTIVE: To assess myocardial involvement in patients with systemic sclerosis (SSc) with no signs or symptoms of cardiac impairment (New York Heart Association functional class I). METHODS: Fifty patients (45 women, 5 men, age 53.3 +/- 12.9 yrs) who did not complain of serious diseases other than SSc were recruited out of 119 consecutive patients with SSc. Thirty-three were found to have limited cutaneous SSc (lSSc) and 17 diffuse SSc (dSSc). All underwent cardiovascular magnetic resonance imaging (MRI) to determine right and left systolic and diastolic volumes and ventricular ejection fractions (RVEF and LVEF). Thirty-one healthy subjects matched for sex, age, and body surface area (BSA) were studied as controls. Diffusion lung capacity test (DLCO) and high resolution computed tomography were performed to evaluate lung involvement. RESULTS: Disease duration between patients with lSSc (14.1 +/- 11.4 yrs) and those with dSSc (6.9 +/-4.4yrs) was found to be significantly different (p < 0.003). lSSc patients were older than those with dSSc (54.8 +/- 13.7 yrs vs 50.4 +/- 9.9 yrs, respectively; p < 0.04). Anticentromere antibodies and Scl-70 were positive in 23 (46%) and 17 patients (34%). Except for the left and right systolic volumes, all unadjusted cardiac MRI measures were significantly reduced in SSc compared to the controls (p < 0.001 and p < 0.009). These differences persisted after adjustment for subjects' height and BSA. Raw RVEF data and RVEF data matched for height and BSA were significantly reduced in dSSc patients in comparison to lSSc (p < 0.03). CONCLUSION: Compromised RVF was found in patients with asymptomatic SSc. Unlike standard diagnostic techniques, cardiac MRI appears to be a rapid and noninvasive means of determining subclinical right myocardial involvement that is otherwise undetected in patients with SSc.

Diagnostic work up of arrhythmogenic right ventricular cardiomyopathy by cardiovascular magnetic resonance (CMR). Consensus statement.

Cardiovascular Magnetic Resonance (CMR) has become a widespread diagnostic tool. Since its introduction CMR has been used to image patients with known or suspected arrhythmogenic right ventricular cardiomyopathy (ARVC). Several abnormalities have been found and described by CMR and at present this diagnostic tool is considered very important for the diagnosis. However, the diagnosis of ARVC relies upon the fulfillment of both clinical and functional criteria and CMR can provide several but not all the information useful for the diagnosis. Furthermore, some findings such as evidence of right ventricular epicardial fat once considered a peculiar marker of ARVC, have been shown to possess a low specificity. This document was prepared by representatives of the three Italian official Organizations involved in CMR. Its main scope is to highlight the problems encountered when studying patients with suspected ARVC by CMR, to indicate the basic technical equipment needed, to recommend a proper imaging protocol and to offer a consensus on the main diagnostic features relevant for the diagnosis.

[Can anxiety and depression influence the six-minute walking test performance in post-surgical heart valve patients? A pilot study]. / Ansia e tono dell'umore possono avere influenza sulla prestazione al test del cammino dei 6 minuti in pazienti sottoposti a intervento di chirurgia valvolare? Uno studio pilota.

UNLABELLED: Various functional indicators are utilized to measure outcome in cardiac rehabilitation. Little information exists regarding the role played by psychological variables during the rehabilitative period, after cardiac valve surgery. The present study aims at exploring the relationship existing between different levels of functional capacity measured by six-minute walking test, (6MWT) and emotional aspects such as anxiety and depression. MATERIALS AND METHODS: 126 post-surgical heart valve patients underwent at the beginning and at the end of the rehabilitative programme: 1) 6MWT; 2) assessment of anxiety and depression (A-D Questionnaire according to the CBA-2.0 Primary Scale). RESULTS: Cardiac rehabilitation was associated with a general and significant improvement in the 6MWT (273 +/- 98 metres versus 363 +/- 96; p < 0.001) and the functional performance parameters (diastolic blood pressure; p < 0.001 and fatigue p < 0.001). Simultaneously there was a significant improvement of patient-reported quality of life, revealed by the A-D questionnaire in both male and female patients. The Depression Questionnaire score is predictive of functional capacity. It was demonstrated that no matter what the clinical condition of the patient, the depression score influences the patient's performance during the 6MWT, not only regards the distance covered (p = .008), but also fatigue expressed by the Borg RPE index (p = .044). CONCLUSION: Depression, an emotional variable, self-evaluated by the standardized questionnaire can, even if only partially, influence the 6MWT, a functional indicator of exercise tolerance, widely utilized in cardiac rehabilitation.
